                            MuniHoldings Fund, Inc.
                   Auction Market Preferred Stock ("AMPS")

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

      MuniHoldings Fund, Inc. is a non-diversified, closed-end fund. The
investment objective of the Fund is to provide shareholders with current
income exempt from Federal income taxes. The Fund seeks to achieve its
investment objective by investing, as a fundamental policy, at least 80% of an
aggregate of the Fund's net assets (including proceeds from the issuance of
preferred stock) and the proceeds of any borrowings for investment purposes,
in a portfolio of municipal obligations the interest on which, in the opinion
of bond counsel to the issuer, is excludable from gross income for Federal
income tax purposes (except that the interest may be includable in taxable
income for purposes of the Federal alternative minimum tax). Under normal
market conditions, the Fund expects to invest at least 75% of its total assets
in municipal obligations that are rated investment grade or, if unrated, are
considered by the Fund's investment adviser to be of comparable quality. The
Fund may invest up to 25% of its total assets in municipal obligations that
are rated below investment grade (commonly known as "junk" bonds) or, if
unrated, are considered by the Fund's investment adviser to possess similar
credit characteristics. The Fund invests primarily in long term municipal
obligations. The Fund may invest in certain tax exempt securities classified
as "private activity bonds," as discussed within, that may subject certain
investors in the Fund to an alternative minimum tax. There can be no assurance
that the Fund's investment objective will be realized.

                                                (continued on following page)

                              PROSPECTUS SUMMARY

      This summary is qualified in its entirety by reference to the detailed
information included in this prospectus and the statement of additional
information.

<TABLE>
<CAPTION>
<S>                         <C>
The Fund                    MuniHoldings Fund, Inc. is a non-diversified, closed-end management investment
                            company.

The Offering                The Fund is offering a total of 600 shares of Auction Market Preferred Stock,
                            Series C, at a purchase price of $25,000 per share plus accumulated dividends, if
                            any, from the date the shares are first issued. The shares of Series C AMPS are
                            being offered by Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill
                            Lynch"), as underwriter.

                            The Series C AMPS will be shares of preferred stock of the Fund that entitle their
                            holders to receive cash dividends at an annual rate that may vary for the
                            successive dividend periods. In general, except as described below, each dividend
                            period following the initial dividend period will be seven days. The applicable
                            dividend for a particular dividend period will be determined by an auction
                            conducted on the business day next preceding the start of that dividend period.

                            Investors and potential investors in shares of Series C AMPS may participate in
                            auctions for the AMPS through their broker-dealers.

                            Generally, AMPS investors will not receive certificates evidencing ownership of
                            their shares. Ownership of AMPS will be maintained in book-entry form by the
                            securities depository (The Depository Trust Company) or its nominee for the
                            account of the investor's agent member (generally the investor's broker-dealer).
                            The investor's agent member, in turn, will maintain records of such investor's
                            beneficial ownership of AMPS.

Investment Objective        The investment objective of the Fund is to provide shareholders with current
and Policies                income exempt from Federal income taxes. The Fund seeks to achieve its investment
                            objective by investing, as a fundamental policy, at least 80% of an aggregate of
                            the Fund's net assets (including proceeds from the issuance of any preferred
                            stock) and the proceeds of any borrowings for investment purposes, in a portfolio
                            of municipal obligations issued by or on behalf of states, territories and
                            possessions of the United States and their political subdivisions, agencies or
                            instrumentalities, each of which pays interest that, in the opinion of bond
                            counsel to the issuer, is excludable from gross income for Federal income tax
                            purposes ("Municipal Bonds"). In general, the Fund does not intend for its
                            investments to earn a large amount of interest income that is not exempt from
                            Federal income tax, except that the interest may be includable in taxable income
                            for purposes of the Federal alternative minimum tax. There can be no assurance
                            that the Fund's investment objective will be realized.

                            Maturity. The average maturity of the Fund's portfolio securities varies from time
                            to time based upon an assessment of economic and market conditions by Fund Asset
                            Management, L.P., the Fund's investment adviser (the "Investment Adviser"). The
                            Fund intends to invest primarily in long term Municipal Bonds (that is, Municipal
                            Bonds with maturities of more than ten years). However, the Fund also may invest
                            in intermediate term Municipal Bonds with remaining maturities of between three
                            years and ten years. The Fund also may invest from time to time in short term
                            Municipal Bonds with remaining maturities of less than three years.

                            Investment Grade Municipal Bonds. Under normal market conditions, the Fund invests
                            at least 75% of its total assets in a portfolio of Municipal Bonds that are rated
                            investment grade by one or more nationally recognized statistical rating
                            organizations ("NRSROs")

                            (Baa or higher by Moody's Investors Service, Inc. ("Moody's") or BBB or higher by
                            Standard & Poor's ("S&P") or Fitch Ratings ("Fitch")) or in unrated bonds
                            considered by the Investment Adviser, to be of comparable quality. In assessing
                            the quality of Municipal Bonds, the Investment Adviser takes into account any
                            letters of credit or similar credit enhancement to which particular Municipal
                            Bonds are entitled and the creditworthiness of the financial institution that
                            provided such credit enhancement.

                            "High Yield" or "Junk" Bonds. The Fund may invest up to 25% of its total assets in
                            high yield Municipal Bonds (commonly known as "junk" bonds) that are rated below
                            investment grade by the NRSROs (Ba or lower by Moody's or BB or lower by S&P or
                            Fitch) or are unrated securities that are considered by the Investment Adviser to
                            possess similar credit characteristics. Although junk bonds generally pay higher
                            rates of interest than investment grade bonds, they are high risk investments that
                            may cause income and principal losses for the Fund. Junk bonds generally are less
                            liquid and experience more price volatility than higher rated debt securities. The
                            issuers of junk bonds may have a larger amount of outstanding debt relative to
                            their assets than issuers of investment grade bonds. In the event of an issuer's
                            bankruptcy, claims of other creditors may have priority over the claims of junk
                            bond holders, leaving few or no assets available to repay junk bond holders. Junk
                            bonds may be subject to greater call and redemption risk than higher rated debt
                            securities.

                            Indexed and Inverse Floating Rate Securities. The Fund may invest in securities
                            whose potential returns are directly related to changes in an underlying index or
                            interest rate, known as indexed securities. The return on indexed securities will
                            rise when the underlying index or interest rate rises and fall when the index or
                            interest rate falls. The Fund may also invest in securities whose return is
                            inversely related to changes in an interest rate (inverse floaters). In general,
                            income on inverse floaters will decrease when short term interest rates increase
                            and increase when short term interest rates decrease. Investments in inverse
                            floaters may subject the Fund to the risks of reduced or eliminated interest
                            payments and loss of principal. In addition, certain indexed securities and
                            inverse floaters may increase or decrease in value at a greater rate than the
                            underlying interest rate, which effectively leverages the Fund's investment. As a
                            result, the market value of such securities will generally be more volatile than
                            that of fixed rate, tax exempt securities. Both indexed securities and inverse
                            floaters are derivative securities and can be considered speculative.

                            Hedging Transactions. The Fund may seek to hedge its portfolio against changes in
                            interest rates using options and financial futures contracts or swap transactions.
                            The Fund's hedging transactions are designed to reduce volatility, but come at
                            some cost. For example, the Fund may try to limit its risk of loss from a decline
                            in price of a portfolio security by purchasing a put option. However, the Fund
                            must pay for the option, and the price of the security may not in fact drop. In
                            large part, the success of the Fund's hedging activities depends on its ability to
                            forecast movements in securities prices and interest rates. The Fund is not
                            required to hedge its portfolio and may choose not to do so. The Fund cannot
                            guarantee that any hedging strategies it uses will work.

                            Swap Agreements. The Fund is authorized to enter into swap agreements, which are
                            over-the-counter contracts in which one party agrees to make periodic payments
                            based on the change in the market value of a specific bond, basket of bonds or
                            index in return for periodic payments based on a fixed or variable interest rate
                            or the change in market value of a different bond, basket of bonds or index. Swap
                            agreements may be used to obtain exposure to a bond or market without owning or
                            taking physical custody of securities.

                            Tax Considerations. While exempt-interest dividends are excluded from gross income
                            for Federal income tax purposes, they may be subject to the Federal alternative
                            minimum tax in certain circumstances. Distributions of any capital gain or other
                            taxable income

                            will be taxable to stockholders. The Fund may not be a suitable investment for
                            investors subject to the Federal alternative minimum tax or who would become
                            subject to such tax by investing in the Fund. See "Taxes."

Risk Factors                Set forth below is a summary of the main risks of investing in the Fund's Series C
                            AMPS. For a more detailed description of the main risks as well as certain other
                            risks associated with investing in the Fund's Series C AMPS, see "Risk Factors and
                            Special Considerations."

                            o  The credit ratings of the AMPS could be reduced or terminated while an investor
                               holds the AMPS, which could affect liquidity.

                            o  Neither broker-dealers nor the Fund are obligated to purchase shares of AMPS in
                               an auction or otherwise, nor is the Fund required to redeem shares of AMPS in
                               the event of a failed auction.

                            o  If sufficient bids do not exist in an auction, the applicable dividend rate
                               will be the maximum applicable dividend rate, and in such event, owners of AMPS
                               wishing to sell will not be able to sell all, and may not be able to sell any,
                               AMPS in the auction. As a result, investors may not have liquidity of
                               investment.

                            o  As a result of bidding by broker-dealers in an auction for their own account,
                               the dividend rate that would apply at the auction may be higher or lower than
                               the rate that would have prevailed had the broker-dealer not bid.

                            o  A broker-dealer may bid in an auction in order to prevent what would otherwise
                               be (i) a failed auction, (ii) an "all-hold" auction, or (iii) an applicable
                               dividend rate that the broker-dealer believes, in its sole discretion, does not
                               reflect the market for the AMPS at the time of the auction.

                            o  The relative buying and selling interest of market participants in AMPS and in
                               the auction rate securities market as a whole will vary over time, and such
                               variations may be affected by, among other things, news relating to the issuer,
                               the attractiveness of alternative investments, the perceived risk of owning the
                               security (whether related to credit, liquidity or any other risk), the tax
                               treatment accorded the instruments, the accounting treatment accorded auction
                               rate securities, including recent clarifications of U.S. generally accepted
                               principles relating to the treatment of auction rate securities, reactions to
                               regulatory actions or press reports, financial reporting cycles and market
                               sentiment generally. Shifts of demand in response to any one or simultaneous
                               particular events cannot be predicted and may be short-lived or exist for
                               longer periods.

                            o  Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") has
                               advised the Fund that it and various other broker-dealers and other firms that
                               participate in the auction rate securities market received letters from the
                               staff of the Securities and Exchange Commission last spring. The letters
                               requested that each of these firms voluntarily conduct an investigation
                               regarding its respective practices and procedures in that market. Pursuant to
                               this request, Merrill Lynch conducted its own voluntary review and reported its
                               findings to the Securities and Exchange Commission staff. At the Securities and
                               Exchange Commission staff's request, Merrill Lynch, together with certain other
                               broker-dealers and other firms that participate in the auction rate securities
                               market, is engaging in discussions with the Securities and Exchange Commission
                               staff concerning its inquiry. Neither Merrill Lynch nor the Fund can predict
                               the ultimate outcome of the inquiry or how that outcome will affect the market
                               for the AMPS or the auctions.



                                                      7

                            o  Broker-dealers have no obligation to maintain a secondary trading market in the
                               AMPS outside of auctions and there can be no assurance that a secondary market
                               for the AMPS will develop or, if it does develop, that it will provide holders
                               with a liquid trading market. An increase in the level of interest rates likely
                               will have an adverse effect on the secondary market price of the AMPS, and a
                               selling stockholder may have to sell AMPS between auctions at a price per share
                               of less than $25,000.

                            o  The Fund will issue the AMPS only if the AMPS have received a rating of Aaa
                               from Moody's and AAA from S&P. Under certain circumstances, the Fund may
                               voluntarily terminate compliance with Moody's or S&P guidelines, or both, in
                               which case the AMPS may no longer be rated by Moody's or S&P, as applicable,
                               but will be rated by at least one rating agency.

                            o  The Fund issues shares of AMPS, which generally pay dividends based on short
                               term interest rates. The Fund generally will purchase Municipal Bonds that pay
                               interest at fixed or adjustable rates. If market interest rates rise, this
                               could negatively impact the value of the Fund's investment portfolio, reducing
                               the amount of assets serving as asset coverage for the AMPS. If the asset
                               coverage becomes too low, the Fund may be required to redeem some or all of the
                               shares of AMPS.

                            o  The Fund is registered as a "non-diversified" investment company, the Fund may
                               invest a greater percentage of its assets in a single issuer than a diversified
                               investment company. Since the Fund may invest a relatively high percentage of
                               its assets in a limited number of issuers, the Fund may be more exposed to any
                               single economic, political or regulatory occurrence than a more widely
                               diversified fund.

                            o  The amount of public information available about 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 the Investment Adviser than the performance of a stock
                               fund or taxable bond fund.

                            o  The Fund's investments in Municipal Bonds are subject to interest rate and
                               credit risk. Interest rate risk is the risk that prices of Municipal Bonds
                               generally increase when interest rates decline and decrease when interest rates
                               increase. Prices of the longer term securities in which the Fund primarily
                               invests generally change more in response to changes in interest rates than
                               prices of shorter term securities. Credit risk is the risk that the issuer will
                               be unable to pay the interest or principal when due. Changes in an issuer's
                               credit rating or the market's perception of an issuer's creditworthiness may
                               affect the value of the Fund's investment in that issuer.

                            o  Investments in junk bonds entail a higher level of credit risk (loss of income
                               and/or principal) and a corresponding greater risk of loss than investments in
                               investment grade Municipal Bonds. Municipal Bonds rated in the lower rating
                               categories are considered to be predominantly speculative with respect to
                               capacity to pay interest and dividend income and repay principal.

Investment Adviser          The Investment Adviser provides investment advisory and administrative services to
                            the Fund. For its services, the Fund pays the Investment Adviser a monthly fee at
                            the annual rate of 0.55% of the Fund's average weekly net assets (including any
                            proceeds from the issuance of preferred stock).

Dividends and               Dividends on the Series C AMPS will be cumulative from the date the shares are
Dividend Periods            first issued and payable at the annualized cash dividend rate for the initial
                            dividend period on the initial dividend payment date as follows:

                            After the initial dividend period, each dividend period for the Series C AMPS will
                            generally consist of seven days; provided however, that, before any auction, the
                            Fund may decide, subject to certain limitations and only if it gives notice to
                            holders, to declare a special dividend period of up to five years.

                            After the initial dividend period, in the case of dividend periods that are not
                            special dividend periods, dividends generally will be payable on each succeeding [
                            ] in the case of the Series C AMPS.

                            Dividends for the Series C AMPS will be paid through the securities depository
                            (The Depository Trust Company) on each dividend payment date for the AMPS.

                            For each subsequent dividend period, the auction agent (The Bank of New York) will
                            hold an auction to determine the cash dividend rate on the shares of Series C
                            AMPS.

Determination of            Generally, the applicable dividend rate for any dividend period for the Series C
Maximum Dividend            AMPS will not be more than the maximum applicable rate attributable to such shares.
Rates                       The maximum applicable rate will be the higher of (A) the applicable percentage of
                            the reference rate on the auction date or (B) the applicable spread plus the
                            reference rate on the auction date. The reference rate is (A) the higher of the
                            applicable LIBOR Rate (as defined in the Glossary) and the Taxable Equivalent of
                            the Short Term Municipal Bond Rate (as defined in the Glossary) (for a dividend
                            period or special dividend period of 364 or fewer days), or (B) the applicable
                            Treasury Index Rate (as defined in the Glossary) (for a special dividend period of
                            365 days or more). The maximum applicable rate for the Series C AMPS will depend
                            on the credit rating assigned to the shares, the length of the dividend period and
                            whether or not the Fund has given notification prior to the auction for the
                            dividend period that any taxable income will be included in the dividend on the
                            AMPS for that dividend period. The applicable percentage and applicable spread are
                            as follows:

                            There is no minimum applicable dividend rate for any dividend period.

Other AMPS                  The Fund has outstanding 4,400 shares of two other series of Auction Market
                            Preferred Stock, each with a liquidation preference of $25,000 per share, plus
                            accumulated but unpaid dividends, for an aggregate initial liquidation preference
                            of $110,000,000 (the "Other AMPS"). The Other AMPS are as follows: 2,200 shares of
                            Auction Market Preferred Stock, Series A and 2,200 shares of Auction Market
                            Preferred Stock, Series B. The Series C AMPS offered hereby rank on a parity with
                            the Other AMPS with respect to dividends and liquidation preference.

Asset Maintenance           Under the Fund's Articles Supplementary creating the Series C AMPS (the "Articles
                            Supplementary"), the Fund must maintain:

                            o  asset coverage of the AMPS and Other AMPS as required by the rating agencies
                               rating the AMPS, and

                            o  asset coverage of the AMPS and Other AMPS of at least 200% as required by the
                               Investment Company Act of 1940 (the "1940 Act").

                            The Fund estimates that, based on the composition of its portfolio at April 30,
                            2005, asset coverage of the AMPS and Other AMPS as required by the 1940 Act would
                            be approximately 280% immediately after the Fund issues the shares of AMPS offered
                            by this prospectus representing approximately 36% of the Fund's capital, or
                            approximately 56% of the Fund's common stock equity, immediately after the
                            issuance of such AMPS.

Mandatory                   If the required asset coverage is not maintained or, when necessary, restored, the
Redemption                  Fund must redeem shares of Series C AMPS at the price of $25,000 per share plus
                            accumulated but unpaid dividends thereon (whether or not earned or declared). The
                            provisions of the 1940 Act may restrict the Fund's ability to make such a
                            mandatory redemption.

Optional Redemption         The Fund may, at its option, choose to redeem all or some of the shares of AMPS on
                            any dividend payment date at the price of $25,000 per share, plus accumulated but
                            unpaid dividends thereon (whether or not earned or declared), plus any applicable
                            premium.

Liquidation Preference      The liquidation preference (that is, the amount the Fund must pay to holders of
                            AMPS if the Fund is liquidated) of each share of AMPS will be $25,000, plus an
                            amount equal to accumulated but unpaid dividends (whether or not earned or
                            declared).

Ratings                     The Series C AMPS will be issued with a rating of Aaa from Moody's and AAA from
                            S&P.

Voting Rights               The 1940 Act requires that the holders of AMPS and any other preferred stock,
                            including the Other AMPS, voting as a separate class, have the right to elect at
                            least two directors at all times and to elect a majority of the directors at any
                            time when dividends on the AMPS or any other preferred stock, including the Other
                            AMPS, are unpaid for two full years. The Fund's Charter, the 1940 Act and the
                            General Corporation Laws of the State of Maryland require holders of AMPS and any
                            other preferred stock, including the Other AMPS, to vote as a separate class on
                            certain other matters.

                   RISK FACTORS AND SPECIAL CONSIDERATIONS

      An investment in the Fund's AMPS should not constitute a complete
investment program.

      Set forth below are the main risks of investing in the Fund's AMPS.

      Investment Considerations. Investors in Series C AMPS should consider
the following factors:

      o   The credit ratings of the AMPS could be reduced or terminated while
          an investor holds the AMPS, which could affect liquidity.

      o   Neither broker-dealers nor the Fund are obligated to purchase shares
          of AMPS in an auction or otherwise, nor is the Fund required to
          redeem shares of AMPS in the event of a failed auction.

      o   If sufficient bids do not exist in an auction, the applicable
          dividend rate will be the maximum applicable dividend rate, and in
          such event, owners of AMPS wishing to sell will not be able to sell
          all, and may not be able to sell any, AMPS in the auction. As a
          result, investors may not have liquidity of investment.

      o   Broker-dealers may submit orders in auctions for the AMPS for their
          own account. If a broker-dealer submits an order for its own account
          in any auction, it may have knowledge of orders placed through it in
          that auction and therefore have an advantage over other bidders, but
          such broker-dealer would not have knowledge of orders submitted by
          other broker-dealers in that auction. As a result of bidding by a
          broker-dealer in an auction, the dividend rate that would apply at
          the auction may be higher or lower than the rate that would have
          prevailed had the broker-dealer not bid.

      o   A broker-dealer may bid in an auction in order to prevent what would
          otherwise be (i) a failed auction, (ii) an "all-hold" auction, or
          (iii) an applicable dividend rate that the broker-dealer believes,
          in its sole discretion, does not reflect the market for the AMPS at
          the time of the auction. A broker-dealer may, but is not obligated
          to, advise owners of AMPS that the dividend rate that would apply in
          an "all-hold" auction may be lower than would apply if owners submit
          bids and such advice, if given, may facilitate the submission of
          bids by owners that would avoid the occurrence of an "all-hold"
          auction.

      o   The relative buying and selling interest of market participants in
          AMPS and in the auction rate securities market as a whole will vary
          over time, and such variations may be affected by, among other
          things, news relating to the issuer, the attractiveness of
          alternative investments, the perceived risk of owning the security
          (whether related to credit, liquidity or any other risk), the tax
          treatment accorded the instruments, the accounting treatment
          accorded auction rate securities, including recent clarifications of
          U.S. generally accepted principles relating to the treatment of
          auction rate securities, reactions to regulatory actions or press
          reports, financial reporting cycles and market sentiment generally.
          Shifts of demand in response to any one or simultaneous particular
          events cannot be predicted and may be short-lived or exist for
          longer periods.

      o   Merrill Lynch has advised the Fund that it and various other
          broker-dealers and other firms that participate in the auction rate
          securities market received letters from the staff of the Securities
          and Exchange Commission last spring. The letters requested that each
          of these firms voluntarily conduct an investigation regarding its
          respective practices and procedures in that market. Pursuant to this
          request, Merrill Lynch conducted its own voluntary review and
          reported its findings to the Securities and Exchange Commission
          staff. At the Securities and Exchange Commission staff's request,
          Merrill Lynch, together with certain other broker-dealers and other
          firms that participate in the auction rate securities market, is
          engaging in discussions with the Securities and Exchange Commission
          staff concerning its inquiry. Neither Merrill Lynch nor the Fund can
          predict the ultimate outcome of the inquiry or how that outcome will
          affect the market for the AMPS or the auctions.



                                      11
<PAGE>

      Secondary Market. Broker-dealers have no obligation to maintain a
secondary trading market in the AMPS outside of auctions and there can be no
assurance that a secondary market for the AMPS will develop or, if it does
develop, that it will provide holders with a liquid trading market. The AMPS
will not be registered on any stock exchange or on any automated quotation
system. An increase in the level of interest rates likely will have an adverse
effect on the secondary market price of the AMPS, and a selling stockholder
may have to sell AMPS between auctions at a price per share of less than
$25,000.

      Rating Agencies. The Fund will issue the AMPS only if the AMPS have
received a rating of Aaa from Moody's and AAA from S&P. As a result of such
ratings, the Fund will be subject to guidelines of Moody's, S&P or another
substitute NRSRO that may issue ratings for its preferred stock. These
guidelines may impose asset coverage or portfolio composition requirements
that are more stringent than those imposed by the 1940 Act and may prohibit or
limit the use by the Fund of certain portfolio management techniques or
investments. The Fund does not expect these guidelines to prevent the
Investment Adviser from managing the Fund's portfolio in accordance with the
Fund's investment objective and policies. Also, under certain circumstances,
the Fund may voluntarily terminate compliance with Moody's or S&P's
guidelines, or both, in which case the AMPS may no longer be rated by Moody's
or S&P, as applicable, but will be rated by at least one rating agency.

      Interest Rate Risk and AMPS. The Fund issues shares of AMPS, which
generally pay dividends based on short term interest rates. The Fund generally
will purchase Municipal Bonds that pay interest at fixed or adjustable rates.
If short term interest rates rise, dividend rates on the shares of AMPS may
rise so that the amount of dividends paid to the holders of shares of AMPS
exceeds the income from the Fund's portfolio securities. Because income from
the Fund's entire investment portfolio (not just the portion of the portfolio
purchased with the proceeds of the AMPS offering) is available to pay
dividends on the shares of AMPS, dividend rates on the shares of AMPS would
need to greatly exceed the Fund's net portfolio income before the Fund's
ability to pay dividends on the shares of AMPS would be jeopardized. If market
interest rates rise, this could negatively impact the value of the Fund's
investment portfolio, reducing the amount of assets serving as asset coverage
for the AMPS. If the asset coverage becomes too low, the Fund may be required
to redeem some or all of the shares of AMPS.

      Non-Diversification. The Fund is registered as a "non-diversified"
investment company. This means that the Fund may invest a greater percentage
of its assets in a single issuer than a diversified investment company. Since
the Fund may invest a relatively high percentage of its assets in a limited
number of issuers, the Fund may be more exposed to any single economic,
political or regulatory occurrence than a more widely diversified fund. Even
as a non-diversified fund, the Fund must still meet the diversification
requirements applicable to regulated investment companies under the Federal
income tax laws.

      Market Risk and Selection Risk. Market risk is the risk that the bond
market will go down in value, including the possibility that the market will
go down sharply and unpredictably. Selection risk is the risk that the
securities that Fund management selects will underperform the bond market, the
relevant indices, or other funds with similar investment objectives and
investment strategies.

      Tax Exempt Securities Market Risk. The amount of public information
available about 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 the
Investment Adviser than the performance of a stock fund or taxable bond fund.

      Interest Rate and Credit Risk. The Fund invests in Municipal Bonds,
which are subject to interest rate and credit risk. Interest rate risk is the
risk that prices of Municipal Bonds generally increase when interest rates
decline and decrease when interest rates increase. Prices of the longer term
securities in which the Fund primarily invests generally change more in
response to interest rate changes than prices of shorter term securities. The
Fund's use of leverage by the issuance of preferred stock and its investment
in inverse floating obligations, as discussed below, may increase interest
rate risk. Because market interest rates are currently near their lowest
levels in many years, there is a greater risk that the Fund's portfolio
securities will decline in value if interest rates increase in the future.
Credit risk is the risk that the issuer will be unable to pay the interest or
principal when due. Changes in an issuer's credit rating or the market's
perception of an issuer's creditworthiness may affect the value of the Fund's
investment in that issuer. The degree of credit risk depends on both the
financial condition of the issuer and the terms of the obligation.



                                      12
<PAGE>

      Risks Associated with Non-Investment Grade Securities. Under normal
market conditions, the Fund expects to invest at least 75% of its total assets
in Municipal Bonds that are rated investment grade by Moody's, S&P or Fitch,
or in unrated Municipal Bonds that are considered by the Investment Adviser to
possess similar credit characteristics. Obligations rated in the lowest
investment grade category may have certain speculative characteristics. The
Fund may invest up to 25% of its total assets in high yield Municipal Bonds
that are rated below investment grade or are unrated securities that are
considered by the Investment Adviser to possess similar credit
characteristics. Securities rated below investment grade, also known as junk
bonds, generally entail greater interest rate and credit risks than investment
grade securities. For example, their prices are more volatile, economic
downturns and financial setbacks may affect their prices more negatively, and
their trading market may be more limited.

      Set forth below are certain other risks associated with investing in the
Fund's AMPS.

      Call and Redemption Risk. A Municipal Bond's issuer may call the bond
for redemption before it matures. If this happens to a Municipal Bond that the
Fund holds, the Fund may lose income and may have to invest the proceeds in
Municipal Bonds with lower yields.

      Rating Categories. The Fund intends to invest in Municipal Bonds that
are rated investment grade by S&P, Moody's or Fitch, or in unrated Municipal
Bonds that are considered by the Investment Adviser to possess similar credit
characteristics. Obligations rated in the lowest investment grade category may
have certain speculative characteristics. For example, their prices are more
volatile, economic downturns and financial setbacks may affect their prices
more negatively, and their trading market may be more limited.

      Reinvestment Risk. Reinvestment risk is the risk that income from the
Fund's Municipal 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
negatively affect the Fund's yield, return or the market price of the common
stock.

      Private Activity Bonds. The Fund may invest in certain tax exempt
securities classified as "private activity bonds." These bonds may subject
certain investors in the Fund to the Federal alternative minimum tax.

      Liquidity of Investments. Certain Municipal Bonds in which the Fund
invests may lack an established secondary trading market or may be otherwise
considered illiquid. Liquidity of a security relates to the ability to easily
dispose of the security and the price to be obtained and does not generally
relate to the credit risk or likelihood of receipt of cash at maturity.
Illiquid securities may trade at a discount from comparable, more liquid
investments.

      Portfolio Strategies. The Fund may engage in various portfolio
strategies both to seek to increase the return of the Fund and to seek to
hedge its portfolio against adverse effects from movements in interest rates
and in the securities markets. These portfolio strategies include the use of
derivatives, such as indexed securities, inverse floating rate securities,
options, futures, options on futures, interest rate swap transactions and
credit default swaps. Such strategies subject the Fund to the risk that, if
the Investment Adviser incorrectly forecasts market values, interest rates or
other applicable factors, the Fund's performance could suffer. Certain of
these strategies, such as investments in inverse floating rate securities and
credit default swaps, may provide investment leverage to the Fund's portfolio.
The Fund is not required to use derivatives or other portfolio strategies to
seek to increase return or to seek to hedge its portfolio and may choose not
to do so. There can be no assurance that the Fund's portfolio strategies will
be effective. Some of the derivative strategies that the Fund may use to seek
to increase its return are riskier than its hedging transactions and have
speculative characteristics. Such strategies do not attempt to limit the
Fund's risk of loss.

      General Risks Related to Derivatives. Derivatives are financial
contracts or instruments whose value depends on, or is derived from, the value
of an underlying asset, reference rate or index (or relationship between two
indices). The Fund may invest in a variety of derivative instruments for
investment purposes, hedging purposes or to seek to increase its return, such
as options, futures contracts and swap agreements. The Fund may use
derivatives as a substitute for taking a position in an underlying security or
other asset and/or as part of a strategy designed to reduce exposure to other
risks, such as interest rate risk. The Fund also may use derivatives to add
leverage to the portfolio and/or to hedge against increases in the Fund's
costs associated with the dividend payments on the



                                      13
<PAGE>

preferred stock, including the AMPS. The Fund also may invest in certain
derivative products that pay tax exempt income interest via a trust or
partnership through which the Fund holds interests in one or more underlying
long term municipal securities. The Fund's use of derivative instruments
involves risks different from, and possibly greater than, the risks associated
with investing directly in securities and other traditional investments.
Derivatives are subject to a number of risks such as liquidity risk, interest
rate risk, credit risk, leverage risk and management risk. They also involve
the risk of mispricing or improper valuation and correlation risk (i.e., the
risk that changes in the value of the derivative may not correlate perfectly
with the underlying asset, rate or index). If the Fund invests in a derivative
instrument it could lose more than the principal amount invested. Moreover,
derivatives raise certain tax, legal, regulatory and accounting issues that
may not be presented by investments in Municipal Bonds, and there is some risk
that certain issues could be resolved in a manner that could adversely impact
the performance of the Fund and/or the tax exempt nature of the dividends paid
by the Fund.

      Also, suitable derivative transactions may not be available in all
circumstances and there can be no assurance that the Fund will engage in these
transactions to reduce exposure to other risks when that would be beneficial.

      Swaps. Swap agreements are types of derivatives. In order to seek to
hedge the value of the Fund's portfolio, to hedge against increases in the
Fund's cost associated with the dividend payments on its outstanding preferred
stock, including the AMPS, or to seek to increase the Fund's return, the Fund
may enter into interest rate or credit default swap transactions. In interest
rate swap transactions, there is a risk that yields will move in the direction
opposite of the direction anticipated by the Fund, which would cause the Fund
to make payments to its counterparty in the transaction that could adversely
affect Fund performance. In addition to the risks applicable to swaps
generally, credit default swap transactions involve special risks because they
are difficult to value, are highly susceptible to liquidity and credit risk,
and generally pay a return to the party that has paid the premium only in the
event of an actual default by the issuer of the underlying obligation (as
opposed to a credit downgrade or other indication of financial difficulty).
The Fund is not required to enter into interest rate or credit default swap
transactions for hedging purposes or to enhance its return and may choose not
to do so.

      Federal Taxability Risk. The Fund intends to minimize the payment of
taxable income to stockholders by investing in Municipal Bonds and other tax
exempt securities in reliance on an opinion of bond counsel to the issuer that
the interest paid on those securities will be excludable from gross income for
Federal income tax purposes. Such securities, however, may be determined for
Federal income tax purpose to pay, or to have paid, taxable income subsequent
to the Fund's acquisition of the securities. In that event, the Internal
Revenue Service may demand that the Fund pay taxes on the affected interest
income, and, if the Fund agrees to do so, the Fund's yield on its common stock
could be adversely affected. A determination that interest on a security held
by the Fund is includable in gross income for Federal income tax purposes
retroactively to its date of issue may, likewise, cause a portion of prior
distributions received by stockholders, including holders of AMPS, to be
taxable to those stockholders in the year of receipt. The Fund will not pay an
Additional Dividend (as defined herein) to a holder of AMPS under these
circumstances.

      Antitakeover Provisions. The Fund's Charter, By-laws and the General
Corporation Law of the State of Maryland include provisions that could limit
the ability of other entities or persons to acquire control of the Fund or to
change the composition of its Board of Directors. Such provisions could limit
the ability of stockholders to sell their shares at a premium over prevailing
market prices by discouraging a third party from seeking to obtain control of
the Fund. See "Description of Capital Stock--Certain Provisions of the Charter
and By-laws."

      Market Disruption. The terrorist attacks in the United States on
September 11, 2001 had a disruptive effect on the securities markets, some of
which were closed for a four-day period. The continued threat of similar
attacks, and related events, including U.S. military actions in Iraq and
continued unrest in the Middle East, have led to increased short term market
volatility and may have long term effects on U.S. and world economies and
markets. Similar disruptions of the financial markets could adversely affect
the market prices of the Fund's portfolio securities, interest rates,
auctions, secondary trading, ratings, credit risk, inflation and other factors
relating to the Fund's AMPS. Non-investment grade securities tend to be more
volatile than investment grade fixed income securities so that these events
and other market disruptions may have a greater impact on the prices and
volatility of non-investment grade securities than on investment grade fixed
income securities. There can be no assurance that



                                      14
<PAGE>

these events and other market disruptions will not have other material and
adverse implications for the non-investment grade securities markets.

                             FINANCIAL HIGHLIGHTS

      The following Financial Highlights table is intended to help you
understand the Fund's financial performance for the years shown. Certain
information reflects financial results for a single share of common stock or
preferred stock of the Fund. The total returns in the table represent the rate
an investor would have earned or lost on an investment in shares of common
stock of the Fund (assuming reinvestment of all dividends). The information
with respect to the fiscal years ended April 30, 1998 to April 30, 2005 has
been audited by , whose report for the fiscal year ended April 30, 2005, along

                       INVESTMENT OBJECTIVE AND POLICIES

      The Fund's investment objective is to provide shareholders with current
income exempt from Federal income taxes. The Fund seeks to achieve its
investment objective by investing, as a fundamental policy, at least 80% of an
aggregate of the Fund's net assets (including proceeds from the issuance of
preferred stock) and the proceeds of any borrowings for investment purposes,
in a portfolio of municipal obligations issued by or on behalf of states,
territories and possessions of the United States and their political
subdivisions, agencies or instrumentalities, each of which pays interest that,
in the opinion of bond counsel to the issuer, is excludable from gross income
for Federal income tax purposes (except that the interest may be includable in
taxable income for purposes of the Federal alternative minimum tax)
("Municipal Bonds"). The Fund's investment objective and its policy of
investing at least 80% of an aggregate of the Fund's net assets (including
proceeds from the issuance of preferred stock) and the proceeds of any
borrowings for investment purposes, in Municipal Bonds are fundamental
policies that may not be changed without the approval of a majority of the
outstanding voting securities of the Fund (as defined in the 1940 Act). There
can be no assurance that the Fund's investment objective will be realized.

      The Fund may invest in certain tax exempt securities classified as
"private activity bonds" (or industrial development bonds, under pre-1986 law)
("PABs") (in general, bonds that benefit non-governmental entities) that may
subject certain investors in the Fund to an alternative minimum tax. See
"Taxes." The percentage of the Fund's total assets invested in PABs will vary
from time to time. The Fund also will not invest more than 25% of its total
assets (taken at market value at the time of each investment) in Municipal
Bonds whose issuers are located in the same state.

      Under normal market conditions, the Fund expects to invest at least 75%
of its total assets in a portfolio of Municipal Bonds that are commonly
referred to as "investment grade" securities, which are obligations rated at
the time of purchase within the four highest quality ratings as determined by
either Moody's Investors Service, Inc. ("Moody's") (currently Aaa, Aa, A and
Baa), Standard & Poor's ("S&P") (currently AAA, AA, A and BBB) or Fitch
Ratings ("Fitch") (currently AAA, AA, A and BBB). In the case of short term
notes, the investment grade rating categories are SP-1+ through SP-2 for S&P,
MIG-1 through MIG-3 for Moody's and F-1+ through F-3 for Fitch. In the case of
tax exempt commercial paper, the investment grade rating categories are A-1+
through A-3 for S&P, Prime-1 through Prime-3 for Moody's and F-1+ through F-3
for Fitch. Obligations ranked in the lowest



                                      18
<PAGE>

investment grade rating category (BBB, SP-2 and A-3 for S&P; Baa, MIG-3 and
Prime-3 for Moody's and BBB and F-3 for Fitch), while considered "investment
grade," may have certain speculative characteristics. There may be
sub-categories or gradations indicating relative standing within the rating
categories set forth above. In assessing the quality of Municipal Bonds with
respect to the foregoing requirements, the Investment Adviser takes into
account the nature of any letters of credit or similar credit enhancement to
which particular Municipal Bonds are entitled and the creditworthiness of the
financial institution that provided such credit enhancement. See Appendix
A--"Description of Municipal Bond Ratings" to the statement of additional
information. If unrated, such securities will possess creditworthiness
comparable, in the opinion of the Investment Adviser, to other obligations in
which the Fund may invest.

      The Fund also may invest up to 25% of its total assets in Municipal
Bonds that are rated below Baa by Moody's or below BBB by S&P or Fitch or, if
unrated, are considered by the Investment Adviser to possess similar credit
characteristics. Such securities, sometimes referred to as "high yield" or
"junk" bonds, are predominantly speculative with respect to the capacity to
pay interest and repay principal in accordance with the terms of the security
and generally involve a greater volatility of price than securities in higher
rating categories. The Fund does not intend to purchase Municipal Bonds that
are in default or which the Investment Adviser believes will soon be in
default. Below investment grade securities and comparable unrated securities
involve substantial risk of loss, are considered speculative with respect to
the issuer's ability to pay interest and any required redemption or principal
payments and are susceptible to default or decline in market value due to
adverse economic and business developments.

      All percentage and ratings limitations on securities in which the Fund
may invest apply at the time of making an investment and shall not be
considered violated if an investment rating is subsequently downgraded to a
rating that would have precluded the Fund's initial investment in such
security. In the event that the Fund disposes of a portfolio security
subsequent to its being downgraded, the Fund may experience a greater risk of
loss than if such security had been sold prior to such downgrade.

      The net asset value of the shares of common stock of a closed-end
investment company, such as the Fund, which invests primarily in fixed income
securities, changes as the general levels of interest rates fluctuate. When
interest rates decline, the value of a fixed income portfolio can be expected
to rise. Conversely, when interest rates rise, the value of a fixed income
portfolio can be expected to decline. Prices of longer term securities in
which the Fund primarily invests generally fluctuate more in response to
interest rate changes than do shorter term securities. These changes in net
asset value are likely to be greater in the case of a fund having a leveraged
capital structure, such as the Fund.

      The Fund intends to invest primarily in long term Municipal Bonds with
maturities of more than ten years. However, the Fund also may invest in
intermediate term Municipal Bonds with maturities of between three years and
ten years. The Fund also may invest from time to time in short term Municipal
Bonds with maturities of less than three years. The average maturity of the
Fund's portfolio securities will vary based upon the Investment Adviser's
assessment of economic and market conditions. As of April 30, 2005, the
weighted average maturity of the Fund's portfolio was approximately 19.87
years.

      For temporary periods or to provide liquidity, the Fund has the
authority to invest as much as 20% of its total assets in tax exempt and
taxable money market obligations with a maturity of one year or less (such
short term obligations being referred to herein as "Temporary Investments").
In addition, the Fund reserves the right as a defensive measure to invest
temporarily a greater portion of its assets in Temporary Investments, when, in
the opinion of the Investment Adviser, prevailing market or financial
conditions warrant. Taxable money market obligations will yield taxable
income. The Fund also may invest in variable rate demand obligations ("VRDOs")
and VRDOs in the form of participation interests ("Participating VRDOs") in
variable rate tax exempt obligations held by a financial institution. See
"Other Investment Policies--Temporary Investments." The Fund's hedging
strategies, which are described in more detail under "Hedging
Transactions--Financial Futures Transactions and Options," are not fundamental
policies and may be modified by the Board of Directors of the Fund without the
approval of the Fund's stockholders. The Fund is also authorized to invest in
indexed and inverse floating rate obligations for hedging purposes and to seek
to enhance return.



                                      19
<PAGE>

      The Fund may invest in securities not issued by or on behalf of a state
or territory or by an agency or instrumentality thereof, if the Fund receives
an opinion of counsel to the issuer that such securities pay interest that is
excludable from gross income for Federal income tax purposes ("Non-Municipal
Tax Exempt Securities"). Non-Municipal Tax Exempt Securities could include
trust certificates, partnership interests or other instruments evidencing
interest in one or more long term municipal securities. Non-Municipal Tax
Exempt Securities also may include securities issued by other investment
companies that invest in Municipal Bonds, to the extent such investments are
permitted by the Fund's investment restrictions and applicable law.
Non-Municipal Tax Exempt Securities are subject to the same risks associated
with an investment in Municipal Bonds as well as many of the risks associated
with investments in derivatives. While the Fund receives opinions of legal
counsel to the effect that the income from the Non-Municipal Tax Exempt
Securities in which the Fund invests is excludable from gross income for
Federal income tax purposes to the same extent as the underlying municipal
securities, the Internal Revenue Service ("IRS") has not issued a ruling on
this subject. Were the IRS to issue an adverse ruling or take an adverse
position with respect to the taxation of these types of securities, there is a
risk that the interest paid on such securities would be deemed taxable at the
Federal level.

      The Fund ordinarily does not intend to realize significant investment
income not exempt from Federal income tax. From time to time, the Fund may
realize taxable capital gains.

      Federal tax legislation has limited the types and volume of bonds the
interest on which qualifies for a Federal income tax exemption. As a result,
this legislation and legislation that may be enacted in the future may affect
the availability of Municipal Bonds for investment by the Fund.

Risk Factors and Special Considerations Relating to Municipal Bonds

      The risks and special considerations involved in investment in Municipal
Bonds vary with the types of instruments being acquired. Investments in
Non-Municipal Tax Exempt Securities may present similar risks, depending on
the particular product. Certain instruments in which the Fund may invest may
be characterized as derivative instruments. See "--Description of Municipal
Bonds" and "--Hedging Transactions--Financial Futures Transactions and
Options."

      The value of Municipal Bonds generally may be affected by uncertainties
in the municipal markets as a result of legislation or litigation, including
legislation or litigation that changes the taxation of Municipal Bonds or the
rights of Municipal Bond holders in the event of a bankruptcy. Municipal
bankruptcies are rare, and certain provisions of the U.S. Bankruptcy Code
governing such bankruptcies are unclear. Further, the application of state law
to Municipal Bond issuers could produce varying results among the states or
among Municipal Bond issuers within a state. These uncertainties could have a
significant impact on the prices of the Municipal Bonds in which the Fund
invests.

Description of Municipal Bonds

      Set forth below is a detailed description of the Municipal Bonds and
Temporary Investments in which the Fund may invest. Information with respect
to ratings assigned to tax exempt obligations that the Fund may purchase is
set forth in Appendix A--"Description of Municipal Bond Ratings" to the
statement of additional information. Obligations are included within the term
Municipal Bonds if the interest paid thereon is excluded from gross income for
Federal income tax purposes in the opinion of bond counsel to the issuer.

      Municipal Bonds include debt obligations issued to obtain funds for
various public purposes, including the construction of a wide range of public
facilities, refunding of outstanding obligations and obtaining funds for
general operating expenses and loans to other public institutions and
facilities. In addition, certain types of bonds are issued by or on behalf of
public authorities to finance various privately owned or operated facilities,
including certain facilities for the local furnishing of electric energy or
gas, sewage facilities, solid waste disposal facilities and other specialized
facilities. Other types of PABs, the proceeds of which are used for the
construction, equipment or improvement of privately operated industrial or
commercial facilities, may constitute Municipal Bonds, although the current
Federal tax laws place substantial limitations on the size of such issues. The
interest on Municipal Bonds may bear a fixed rate or be payable at a variable
or floating rate. The two principal classifications of Municipal Bonds are
"general obligation" and "revenue" bonds, which latter category includes PABs.



                                      20
<PAGE>

      The Fund has not established any limit on the percentage of its
portfolio that may be invested in PABs. The Fund may not be a suitable
investment for investors who are already subject to the Federal alternative
minimum tax or who would become subject to the Federal alternative minimum tax
as a result of an investment in the Fund's common stock. See "Taxes."

      General Obligation Bonds. General obligation bonds are secured by the
issuer's pledge of its faith, credit and taxing power for the payment of
principal and interest. The taxing power of any governmental entity may be
limited, however, by provisions of its state constitution or laws, and an
entity's creditworthiness will depend on many factors, including potential
erosion of its tax base due to population declines, natural disasters,
declines in the state's industrial base or inability to attract new
industries, economic limits on the ability to tax without eroding the tax
base, state legislative proposals or voter initiatives to limit ad valorem
real property taxes and the extent to which the entity relies on Federal or
state aid, access to capital markets or other factors beyond the state's or
entity's control. Accordingly, the capacity of the issuer of a general
obligation bond as to the timely payment of interest and the repayment of
principal when due is affected by the issuer's maintenance of its tax base.

      Revenue Bonds. Revenue bonds are payable only from the revenues derived
from a particular facility or class of facilities or, in some cases, from the
proceeds of a special excise tax or other specific revenue sources such as
payments from the user of the facility being financed. Accordingly, the timely
payment of interest and the repayment of principal in accordance with the
terms of the revenue or special obligation bond is a function of the economic
viability of such facility or such revenue source.

      PABs. The Fund may purchase PABs. PABs are, in most cases, tax exempt
securities issued by states, municipalities or public authorities to provide
funds, usually through a loan or lease arrangement, to a private entity for
the purpose of financing construction or improvement of a facility to be used
by the entity. Such bonds are secured primarily by revenues derived from loan
repayments or lease payments due from the entity which may or may not be
guaranteed by a parent company or otherwise secured. PABs generally are not
secured by a pledge of the taxing power of the issuer of such bonds.
Therefore, an investor should be aware that repayment of such bonds generally
depends on the revenues of a private entity and be aware of the risks that
such an investment may entail. Continued ability of an entity to generate
sufficient revenues for the payment of principal and interest on such bonds
will be affected by many factors including the size of the entity, capital
structure, demand for its products or services, competition, general economic
conditions, government regulation and the entity's dependence on revenues for
the operation of the particular facility being financed.

      Moral Obligation Bonds. The Fund also may invest in "moral obligation"
bonds, which are normally issued by special purpose public authorities. If an
issuer of moral obligation bonds is unable to meet its obligations, the
repayment of such bonds becomes a moral commitment but not a legal obligation
of the state or municipality in question.

      Municipal Lease Obligations. Also included within the general category
of Municipal Bonds are certificates of participation ("COPs") issued by
government authorities or entities to finance the acquisition or construction
of equipment, land and/or facilities. COPs represent participations in a
lease, an installment purchase contract or a conditional sales contract
(hereinafter collectively called "lease obligations") relating to such
equipment, land or facilities. Although lease obligations do not constitute
general obligations of the issuer for which the issuer's unlimited taxing
power is pledged, a lease obligation is frequently backed by the issuer's
covenant to budget for, appropriate and make the payments due under the lease
obligation. However, certain lease obligations contain "non-appropriation"
clauses which provide that the issuer has no obligation to make lease or
installment purchase payments in future years unless money is appropriated for
such purpose on a yearly basis. Although "non-appropriation" lease obligations
are secured by the leased property, disposition of the property in the event
of foreclosure might prove difficult and the value of the property may be
insufficient to issue lease obligations. Certain investments in lease
obligations may be illiquid.

      Indexed and Inverse Floating Rate Securities. The Fund may invest in
Municipal Bonds (and Non- Municipal Tax Exempt Securities) that yield a return
based on a particular index of value or interest rates. For example, the Fund
may invest in Municipal Bonds that pay interest based on an index of Municipal
Bond interest rates. The principal amount payable upon maturity of certain
Municipal Bonds also may be based on the value of the index. To the extent the
Fund invests in these types of Municipal Bonds, the Fund's return on such
Municipal



                                      21
<PAGE>

Bonds will be subject to risk with respect to the value of the particular
index. Interest and principal payable on the Municipal Bonds may also be based
on relative changes among particular indices. Also, the Fund may invest in
so-called "inverse floating obligations" or "residual interest bonds" on which
the interest rates vary inversely with a short term floating rate (which may
be reset periodically by a dutch auction, a remarketing agent, or by reference
to a short term tax exempt interest rate index). The Fund may purchase
synthetically created inverse floating rate bonds evidenced by custodial or
trust receipts. Generally, income on inverse floating rate bonds will decrease
when short term interest rates increase, and will increase when short term
interest rates decrease. Such securities have the effect of providing a degree
of investment leverage, since they may increase or decrease in value in
response to changes, as an illustration, in market interest rates at a rate
which is a multiple (typically two) of the rate at which fixed rate long term
tax exempt securities increase or decrease in response to such changes. As a
result, the market values of such securities will generally be more volatile
than the market values of fixed rate tax exempt securities. To seek to limit
the volatility of these securities, the Fund may purchase inverse floating
obligations with shorter-term maturities or which contain limitations on the
extent to which the interest rate may vary. Certain investments in such
obligations may be illiquid.

      When Issued Securities, Delayed Delivery Securities and Forward
Commitments. The Fund may purchase or sell securities that it is entitled to
receive on a when issued basis. The Fund may also purchase or sell securities
on a delayed delivery basis. The Fund may also purchase or sell securities
through a forward commitment. These transactions involve the purchase or sale
of securities by the Fund at an established price with payment and delivery
taking place in the future. The purchase will be recorded on the date the Fund
enters into the commitment and the value of the securities will thereafter be
reflected in the Fund's net asset value. The Fund enters into these
transactions to obtain what is considered an advantageous price to the Fund at
the time of entering into the transaction. The Fund has not established any
limit on the percentage of its assets that may be committed in connection with
these transactions. When the Fund purchases securities in these transactions,
the Fund segregates liquid securities in an amount equal to the amount of its
purchase commitments.

      There can be no assurance that a security purchased on a when issued
basis will be issued or that a security purchased or sold through a forward
commitment will be delivered. A default by a counterparty may result in the
Fund missing the opportunity of obtaining a price considered to be
advantageous. The value of securities in these transactions on the delivery
date may be more or less than the Fund's purchase price. The Fund may bear the
risk of a decline in the value of the security in these transactions and may
not benefit from an appreciation in the value of the security during the
commitment period.

      Call Rights. The Fund may purchase a Municipal Bond issuer's right to
call all or a portion of such Municipal Bond for mandatory tender for purchase
(a "Call Right"). A holder of a Call Right may exercise such right to require
a mandatory tender for the purchase of related Municipal Bonds, subject to
certain conditions. A Call Right that is not exercised prior to maturity of
the related Municipal Bond will expire without value. The economic effect of
holding both the Call Right and the related Municipal Bond is identical to
holding a Municipal Bond as a non-callable security. Certain investments in
such obligations may be illiquid.

      "High Yield" or "Junk" Bonds. The Fund may invest up to 25% of its total
assets in high yield Municipal Bonds that are rated below Baa by Moody's or
below BBB by S&P or Fitch or are unrated securities that are considered by the
Investment Adviser to possess similar credit characteristics. See Appendix A
"Description of Municipal Bond Ratings" to the statement of additional
information for additional information regarding ratings of Municipal Bonds.
Junk bonds are debt securities that are rated below investment grade by the
major rating agencies or are unrated securities that are considered by the
Investment Adviser to possess similar credit characteristics. Although junk
bonds generally pay higher rates of interest than investment grade bonds, they
are high risk investments that may cause income and principal losses for the
Fund. The major risks in junk bond investments include the following:

o   Junk bonds may be issued by less creditworthy issuers. These securities are
    vulnerable to adverse changes in the issuer's industry and to general
    economic conditions. Issuers of junk bonds may be unable to meet their
    interest or principal payment obligations because of an economic downturn,
    specific issuer developments or the unavailability of additional financing.



                                      22
<PAGE>

o   The issuers of junk bonds may have a larger amount of outstanding debt
    relative to their assets than issuers of investment grade bonds. If the
    issuer experiences financial difficulties, it may be unable to meet its
    debt obligations. The issuer's ability to pay its debt obligations also
    may be lessened by specific issuer developments, or the unavailability of
    additional financing.

o   Junk bonds are frequently ranked junior to claims by other creditors. If
    the issuer cannot meet its obligations, the senior obligations are
    generally paid off before the junior obligations.

o   Junk bonds frequently have call or redemption features that permit an
    issuer to repurchase the security from the Fund before it matures. If an
    issuer redeems the junk bonds, the Fund may have to invest the proceeds in
    bonds with lower yields and may lose income.

o   Prices of junk bonds are subject to extreme price fluctuations. Negative
    economic developments may have a greater impact on the prices of junk
    bonds than on other higher rated fixed income securities.

o   Junk bonds may be less liquid than higher rated fixed income securities
    even under normal economic conditions. There are fewer dealers in the junk
    bond market, and there may be significant differences in the prices quoted
    for junk bonds by the dealers. Because they are less liquid, judgment may
    play a greater role in valuing certain of the Fund's portfolio securities
    than in the case of securities trading in a more liquid market.

      The Fund may incur expenses to the extent necessary to seek recovery
upon default or to negotiate new terms with a defaulting issuer.

      Yields. Yields on Municipal Bonds are dependent on a variety of factors,
including the general condition of the money market and of the municipal bond
market, the size of a particular offering, the financial condition of the
issuer, the maturity of the obligation and the rating of the issue. The
ability of the Fund to achieve its investment objective is also dependent on
the continuing ability of the issuers of the securities in which the Fund
invests to meet their obligations for the payment of interest and principal
when due. There are variations in the risks involved in holding Municipal
Bonds, both within a particular classification and between classifications,
depending on numerous factors. Furthermore, the rights of owners of Municipal
Bonds and the obligations of the issuer of such Municipal Bonds may be subject
to applicable bankruptcy, insolvency and similar laws and court decisions
affecting the rights of creditors generally and to general equitable
principles, which may limit the enforcement of certain remedies.

Hedging Transactions

      The Fund may hedge all or a portion of its portfolio investments against
fluctuations in interest rates through the use of options and certain
financial futures contracts and options thereon. While the Fund's use of
hedging strategies is intended to reduce the volatility of the net asset value
of the Fund's shares of common stock, the net asset value of the Fund's shares
of common stock will fluctuate. No assurance can be given that the Fund's
hedging transactions will be effective. The Fund only may engage in hedging
activities from time to time and may not necessarily be engaging in hedging
activities when movements in interest rates occur. The Fund has no obligation
to enter into hedging transactions and may choose not to do so. Furthermore,
for so long as the AMPS are rated by Moody's and S&P, the Fund's use of
options and certain financial futures and options thereon will be subject to
the limitations described under "Rating Agency Guidelines."

      Financial Futures Transactions and Options. The Fund is authorized to
purchase and sell certain exchange traded financial futures contracts
("financial futures contracts") in order to hedge its investments in Municipal
Bonds against declines in value, and to hedge against increases in the cost of
securities it intends to purchase or to seek to enhance the Fund's return.
However, any transactions involving financial futures or options (including
puts and calls associated therewith) will be in accordance with the Fund's
investment policies and limitations. A financial futures contract obligates
the seller of a contract to deliver and the purchaser of a contract to take
delivery of the type of financial instrument covered by the contract, or in
the case of index-based futures contracts to make and accept a cash
settlement, at a specific future time for a specified price. To hedge its
portfolio, the Fund may take an investment position in a futures contract
which will move in the opposite direction from the portfolio position being



                                      23
<PAGE>

hedged. A sale of financial futures contracts may provide a hedge against a
decline in the value of portfolio securities because such depreciation may be
offset, in whole or in part, by an increase in the value of the position in
the financial futures contracts. A purchase of financial futures contracts may
provide a hedge against an increase in the cost of securities intended to be
purchased because such appreciation may be offset, in whole or in part, by an
increase in the value of the position in the futures contracts.

      Distributions, if any, of net long term capital gains from certain
transactions in futures or options are taxable at long term capital gains
rates for Federal income tax purposes. See "Taxes."

      Futures Contracts. A futures contract is an agreement between two
parties to buy and sell a security or, in the case of an index-based futures
contract, to make and accept a cash settlement for a set price on a future
date. A majority of transactions in futures contracts, however, do not result
in the actual delivery of the underlying instrument or cash settlement, but
are settled through liquidation, i.e., by entering into an offsetting
transaction. Futures contracts have been designed by boards of trade which
have been designated "contracts markets" by the Commodity Futures Trading
Commission ("CFTC").

      The purchase or sale of a futures contract differs from the purchase or
sale of a security in that no price or premium is paid or received. Instead,
an amount of cash or securities acceptable to the broker and the relevant
contract market, which varies, but is generally about 5% of the contract
amount, must be deposited with the broker. This amount is known as "initial
margin" and represents a "good faith" deposit assuring the performance of both
the purchaser and seller under the futures contract. Subsequent payments to
and from the broker, called "variation margin," are required to be made on a
daily basis as the price of the futures contract fluctuates making the long
and short positions in the futures contract more or less valuable, a process
known as "marking to the market." At any time prior to the settlement date of
the futures contract, the position may be closed out by taking an opposite
position that will operate to terminate the position in the futures contract.
A final determination of variation margin is then made, additional cash is
required to be paid to or released by the broker and the purchaser realizes a
loss or gain. In addition, a nominal commission is paid on each completed sale
transaction.

      The Fund deals in financial futures contracts based on a long term
municipal bond index developed by the Chicago Board of Trade ("CBT") and The
Bond Buyer (the "Municipal Bond Index"). The Municipal Bond Index is comprised
of 40 tax exempt municipal revenue and general obligation bonds. Each bond
included in the Municipal Bond Index must be rated A or higher by Moody's or
S&P and must have a remaining maturity of 19 years or more. Twice a month new
issues satisfying the eligibility requirements are added to, and an equal
number of old issues are deleted from, the Municipal Bond Index. The value of
the Municipal Bond Index is computed daily according to a formula based on the
price of each bond in the Municipal Bond Index, as evaluated by six
dealer-to-dealer brokers.

      The Municipal Bond Index futures contract is traded only on the CBT.
Like other contract markets, the CBT assures performance under futures
contracts through a clearing corporation, a nonprofit organization managed by
the exchange membership which is also responsible for handling daily
accounting of deposits or withdrawals of margin.

      The Fund may also purchase and sell financial futures contracts on U.S.
Government securities as a hedge against adverse changes in interest rates as
described below. With respect to U.S. Government securities, currently there
are financial futures contracts based on long term U.S. Treasury bonds, U.S.
Treasury notes, Government National Mortgage Association ("GNMA") Certificates
and three-month U.S. Treasury bills. The Fund may purchase and write call and
put options on futures contracts on U.S. Government securities and purchase
and sell Municipal Bond Index futures contracts in connection with its hedging
strategies.

      The Fund also may engage in other futures contracts transactions such as
futures contracts on other municipal bond indices that may become available if
the Investment Adviser should determine that there is normally a sufficient
correlation between the prices of such futures contracts and the Municipal
Bonds in which the Fund invests to make such hedging appropriate.

      Futures Strategies. The Fund may sell a financial futures contract
(i.e., assume a short position) in anticipation of a decline in the value of
its investments in Municipal Bonds resulting from an increase in interest



                                      24
<PAGE>

rates or otherwise. The risk of decline could be reduced without employing
futures as a hedge by selling such Municipal Bonds and either reinvesting the
proceeds in securities with shorter maturities or by holding assets in cash.
This strategy, however, entails increased transaction costs in the form of
dealer spreads and typically would reduce the average yield of the Fund's
portfolio securities as a result of the shortening of maturities. The sale of
futures contracts provides an alternative means of hedging against declines in
the value of its investments in Municipal Bonds. As such values decline, the
value of the Fund's positions in the futures contracts will tend to increase,
thus offsetting all or a portion of the depreciation in the market value of
the Fund's Municipal Bond investments that are being hedged. While the Fund
will incur commission expenses in selling and closing out futures positions,
commissions on futures transactions are lower than transaction costs incurred
in the purchase and sale of Municipal Bonds. In addition, the ability of the
Fund to trade in the standardized contracts available in the futures markets
may offer a more effective defensive position than a program to reduce the
average maturity of the portfolio securities due to the unique and varied
credit and technical characteristics of the municipal debt instruments
available to the Fund. Employing futures as a hedge also may permit the Fund
to assume a defensive posture without reducing the yield on its investments
beyond any amounts required to engage in futures trading.

      When the Fund intends to purchase Municipal Bonds, the Fund may purchase
futures contracts as a hedge against any increase in the cost of such
Municipal Bonds resulting from a decrease in interest rates or otherwise, that
may occur before such purchases can be effected. Subject to the degree of
correlation between the Municipal Bonds and the futures contracts, subsequent
increases in the cost of Municipal Bonds should be reflected in the value of
the futures held by the Fund. As such purchases are made, an equivalent amount
of futures contracts will be closed out. Due to changing market conditions and
interest rate forecasts, however, a futures position may be terminated without
a corresponding purchase of portfolio securities.

      Call Options on Futures Contracts. The Fund may also purchase and sell
exchange traded call and put options on financial futures contracts. The
purchase of a call option on a futures contract is analogous to the purchase
of a call option on an individual security. Depending on the pricing of the
option compared to either the futures contract upon which it is based or the
price of the underlying debt securities, it may or may not be less risky than
ownership of the futures contract or underlying debt securities. Like the
purchase of a futures contract, the Fund will purchase a call option on a
futures contract to hedge against a market advance when the Fund is not fully
invested.

      The writing of a call option on a futures contract constitutes a partial
hedge against declining prices of the securities which are deliverable upon
exercise of the futures contract. If the futures price at expiration is below
the exercise price, the Fund will retain the full amount of the option premium
which provides a partial hedge against any decline that may have occurred in
the Fund's portfolio holdings.

      Put Options on Futures Contracts. The purchase of a put option on a
futures contract is analogous to the purchase of a protective put option on
portfolio securities. The Fund will purchase a put option on a futures
contract to hedge the Fund's portfolio against the risk of rising interest
rates.

      The writing of a put option on a futures contract constitutes a partial
hedge against increasing prices of the securities which are deliverable upon
exercise of the futures contract. If the futures price at expiration is higher
than the exercise price, the Fund will retain the full amount of the option
premium which provides a partial hedge against any increase in the price of
Municipal Bonds which the Fund intends to purchase.

      The writer of an option on a futures contract is required to deposit
initial and variation margin pursuant to requirements similar to those
applicable to futures contracts. Premiums received from the writing of an
option will be included in initial margin. The writing of an option on a
futures contract involves risks similar to those relating to futures
contracts.

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

      Under regulations of the CFTC, the futures trading activity described
herein will not result in the Fund being deemed a "commodity pool" and the
Fund need not be operated by a person registered with the CFTC as a "commodity
pool operator."



                                      25
<PAGE>

      When the Fund purchases a futures contract, or writes a put option or
purchases a call option thereon, an amount of cash, cash equivalents (e.g.,
high grade commercial paper and daily tender adjustable notes) or liquid
securities will be segregated so that the amount so segregated, plus the
amount of initial and variation margin held in the account of its broker,
equals the market value of the futures contracts, thereby ensuring that the
use of such futures contract is unleveraged. It is not anticipated that
transactions in futures contracts will have the effect of increasing portfolio
turnover.

      Risk Factors in Futures Transactions and Options. Investment in futures
contracts involves the risk of imperfect correlation between movements in the
price of the futures contract and the price of the security being hedged. The
hedge will not be fully effective when there is imperfect correlation between
the movements in the prices of two financial instruments. For example, if the
price of the futures contract moves more or less than the price of the hedged
security, the Fund will experience either a loss or gain on the futures
contract which is not completely offset by movements in the price of the
hedged securities. To compensate for imperfect correlations, the Fund may
purchase or sell futures contracts in a greater dollar amount than the hedged
securities if the volatility of the hedged securities is historically greater
than the volatility of the futures contracts. Conversely, the Fund may
purchase or sell fewer futures contracts if the volatility of the price of the
hedged securities is historically less than that of the futures contracts.

      The particular municipal bonds comprising the index underlying the
Municipal Bond Index financial futures contract may vary from the bonds held
by the Fund. As a result, the Fund's ability to hedge effectively all or a
portion of the value of its Municipal Bonds through the use of such financial
futures contracts will depend in part on the degree to which price movements
in the index underlying the financial futures contract correlate with the
price movements of the Municipal Bonds held by the Fund. The correlation may
be affected by disparities in the average maturity, ratings, geographical mix
or structure of the Fund's investments as compared to those comprising the
Municipal Bond Index and general economic or political factors. In addition,
the correlation between movements in the value of the Municipal Bond Index may
be subject to change over time as additions to and deletions from the
Municipal Bond Index alter its structure. The correlation between futures
contracts on U.S. Government securities and the Municipal Bonds held by the
Fund may be adversely affected by similar factors and the risk of imperfect
correlation between movements in the prices of such futures contracts and the
prices of Municipal Bonds held by the Fund may be greater. Municipal Bond
Index futures contracts were approved for trading in 1986. Trading in such
futures contracts may tend to be less liquid than trading in other futures
contracts. The trading of futures contracts also is subject to certain market
risks, such as inadequate trading activity, which could at times make it
difficult or impossible to liquidate existing positions.

      The Fund expects to liquidate a majority of the futures contracts it
enters into through offsetting transactions on the applicable contract market.
There can be no assurance, however, that a liquid secondary market will exist
for any particular futures contract at any specific time. Thus, it may not be
possible to close out a futures position. In the event of adverse price
movements, the Fund would continue to be required to make daily cash payments
of variation margin. In such situations, if the Fund has insufficient cash, it
may be required to sell portfolio securities to meet daily variation margin
requirements at a time when it may be disadvantageous to do so. The inability
to close out futures positions also could have an adverse impact on the Fund's
ability to hedge effectively its investments in Municipal Bonds. The liquidity
of a secondary market in a futures contract may be adversely affected by
"daily price fluctuation limits" established by commodity exchanges which
limit the amount of fluctuation in a futures contract price during a single
trading day. Once the daily limit has been reached in the contract, no trades
may be entered into at a price beyond the limit, thus preventing the
liquidation of open futures positions. Prices have in the past moved beyond
the daily limit on a number of consecutive trading days. The Fund will enter
into a futures position only if, in the judgment of the Investment Adviser,
there appears to be an actively traded secondary market for such futures
contracts.

      The successful use of transactions in futures and related options also
depends on the ability of the Investment Adviser to forecast correctly the
direction and extent of interest rate movements within a given time frame. To
the extent interest rates remain stable during the period in which a futures
contract or option is held by the Fund or such rates move in a direction
opposite to that anticipated, the Fund may realize a loss on the hedging
transaction which is not fully or partially offset by an increase in the value
of portfolio securities. As a result, the Fund's total return for such period
may be less than if it had not engaged in the hedging transaction.



                                      26
<PAGE>

      Because of low initial margin deposits made upon the opening of a
futures position, futures transactions involve substantial leverage. As a
result, relatively small movements in the price of the futures contracts can
result in substantial unrealized gains or losses. There is also the risk of
loss by the Fund of margin deposits in the event of bankruptcy of a broker
with whom the Fund has an open position in a financial futures contract.
Because the Fund will engage in the purchase and sale of futures contracts for
hedging purposes or to seek to enhance the Fund's return, any losses incurred
in connection therewith should, if the hedging strategy is successful, be
offset in whole or in part by increases in the value of securities held by the
Fund or decreases in the price of securities the Fund intends to acquire.

      The amount of risk the Fund assumes when it purchases an option on a
futures contract is the premium paid for the option plus related transaction
costs. In addition to the correlation risks discussed above, the purchase of
an option on a futures contract also entails the risk that changes in the
value of the underlying futures contract will not be fully reflected in the
value of the option purchased.

                           OTHER INVESTMENT POLICIES

      The Fund has adopted certain other policies as set forth below.

Temporary Investments

      The Fund may invest in short term tax exempt and taxable securities
subject to the limitations set forth above. The tax exempt money market
securities may include municipal notes, municipal commercial paper, municipal
bonds with a remaining maturity of less than one year, variable rate demand
notes and participations therein. Municipal notes include tax anticipation
notes, bond anticipation notes, revenue anticipation notes and grant
anticipation notes. Anticipation notes are sold as interim financing in
anticipation of tax collection, bond sales, government grants or revenue
receipts. Municipal commercial paper refers to short term unsecured promissory
notes generally issued to finance short term credit needs. The taxable money
market securities in which the Fund may invest as Temporary Investments
consist of U.S. Government securities, U.S. Government agency securities,
domestic bank or savings institution certificates of deposit and bankers'
acceptances, short term corporate debt securities such as commercial paper and
repurchase agreements. These Temporary Investments must have a stated maturity
not in excess of one year from the date of purchase. The Fund may not invest
in any security issued by a commercial bank or a savings institution unless
the bank or institution is organized and operating in the United States, has
total assets of at least one billion dollars and is a member of the Federal
Deposit Insurance Corporation ("FDIC"), except that up to 10% of total assets
may be invested in certificates of deposit of smaller institutions if such
certificates are fully insured by the FDIC.

Interest Rate Swap Transactions

      In order to seek to hedge the value of the Fund against interest rate
fluctuations, to hedge against increases in the Fund's costs associated with
the dividend payments on any preferred stock, including the AMPS, or to seek
to increase the Fund's return, the Fund may enter into interest rate swap
transactions such as Municipal Market Data AAA Cash Curve swaps ("MMD Swaps")
or Bond Market Association Municipal Swap Index swaps ("BMA Swaps"). To the
extent that the Fund enters into these transactions, the Fund expects to do so
primarily to preserve a return or spread on a particular investment or portion
of its portfolio as a duration management technique or to protect against any
increase in the price of securities the Fund anticipates purchasing at a later
date. The Fund may enter into these transactions primarily as a hedge or for
duration or risk management rather than as a speculative investment. However,
the Fund also may invest in MMD Swaps and BMA Swaps to seek to enhance return
or gain or to increase the Fund's yield, for example, during periods of steep
interest rate yield curves (i.e., wide differences between short term and long
term interest rates).

      The Fund may purchase and sell BMA Swaps in the BMA swap market. In a
BMA Swap, the Fund exchanges with another party their respective commitments
to pay or receive interest (e.g., an exchange of fixed rate payments for
floating rate payments linked to the Bond Market Association Municipal Swap
Index). Because the underlying index is a tax exempt index, BMA Swaps may
reduce cross-market risks incurred by the Fund and increase the Fund's ability
to hedge effectively. BMA Swaps are typically quoted for the entire yield
curve, beginning with a seven day floating rate index out to 30 years. The
duration of a BMA Swap is approximately equal



                                      27
<PAGE>

to the duration of a fixed rate Municipal Bond with the same attributes as the
swap (e.g., coupon, maturity, call feature).

      The Fund also may purchase and sell MMD Swaps, also known as MMD rate
locks. An MMD Swap permits the Fund to lock in a specified municipal interest
rate for a portion of its portfolio to preserve a return on a particular
investment or a portion of its portfolio as a duration management technique or
to protect against any increase in the price of securities to be purchased at
a later date. By using an MMD Swap, the Fund can create a synthetic long or
short position, allowing the Fund to select the most attractive part of the
yield curve. An MMD Swap is a contract between the Fund and an MMD Swap
provider pursuant to which the parties agree to make payments to each other on
a notional amount, contingent upon whether the Municipal Market Data AAA
General Obligation Scale is above or below a specified level on the expiration
date of the contract. For example, if the Fund buys an MMD Swap and the
Municipal Market Data AAA General Obligation Scale is below the specified
level on the expiration date, the counterparty to the contract will make a
payment to the Fund equal to the specified level minus the actual level,
multiplied by the notional amount of the contract. If the Municipal Market
Data AAA General Obligation Scale is above the specified level on the
expiration date, the Fund will make a payment to the counterparty equal to the
actual level minus the specified level, multiplied by the notional amount of
the contract.

      In connection with investments in BMA and MMD Swaps, there is a risk
that municipal yields will move in the opposite direction than anticipated by
the Fund, which would cause the Fund to make payments to its counterparty in
the transaction that could adversely affect the Fund's performance.

      The Fund has no obligation to enter into BMA or MMD Swaps and may not do
so. The net amount of the excess, if any, of the Fund's obligations over its
entitlements with respect to each interest rate swap will be accrued on a
daily basis, and the Fund will segregate liquid securities having an aggregate
net asset value at least equal to the accrued excess.

Credit Default Swap Agreements

      The Fund may enter into credit default swap agreements for hedging
purposes or to seek to increase its return. The credit default swap agreement
may have as reference obligations one or more securities that are not
currently held by the Fund. The protection "buyer" in a credit default
contract may be obligated to pay the protection "seller" an upfront or a
periodic stream of payments over the term of the contract provided that no
credit event on a reference obligation has occurred. If a credit event occurs,
the seller generally must pay the buyer the "par value" (full notional value)
of the swap in exchange for an equal face amount of deliverable obligations of
the reference entity described in the swap, or the seller may be required to
deliver the related net cash amount, if the swap is cash settled. The Fund may
be either the buyer or seller in the transaction. If the Fund is a buyer and
no credit event occurs, the Fund may recover nothing if the swap is held
through its termination date. However, if a credit event occurs, the buyer
generally may elect to receive the full notional value of the swap in exchange
for an equal face amount of deliverable obligations of the reference entity
whose value may have significantly decreased. As a seller, the Fund generally
receives an upfront payment or a fixed rate of income throughout the term of
the swap, which typically is between six months and three years, provided that
there is no credit event. If a credit event occurs, generally the seller must
pay the buyer the full notional value of the swap in exchange for an equal
face amount of deliverable obligations of the reference entity whose value may
have significantly decreased. As the seller, the Fund would effectively add
leverage to its portfolio because, in addition to its total net assets, the
Fund would be subject to investment exposure on the notional amount of the
swap.

      Credit default swap agreements involve greater risks than if the Fund
had invested in the reference obligation directly since, in addition to
general market risks, credit default swaps are subject to illiquidity risk,
counterparty risk and credit risks. The Fund will enter into credit default
swap agreements only with counterparties who are rated investment grade
quality by at least one nationally recognized statistical rating organization
at the time of entering into such transaction or whose creditworthiness is
believed by the Investment Adviser to be equivalent to such rating. A buyer
generally also will lose its investment and recover nothing should no credit
event occur and the swap is held to its termination date. If a credit event
were to occur, the value of any deliverable obligation received by the seller,
coupled with the upfront or periodic payments previously received, may be less
than the full notional value it pays to the buyer, resulting in a loss of
value to the seller. The Fund's obligations under a credit default swap
agreement will be accrued daily (offset against any amounts owing to the
Fund). The Fund will at all times



                                      28
<PAGE>

segregate with its custodian in connection with each such transaction liquid
securities or cash with a value at least equal to the Fund's exposure (any
accrued but unpaid net amounts owed by the Fund to any counterparty), on a
marked-to-market basis (as calculated pursuant to requirements of the
Securities and Exchange Commission). Such segregation will ensure that the
Fund has assets available to satisfy its obligations with respect to the
transaction and will avoid any potential leveraging of the Fund's portfolio.
Such segregation will not limit the Fund's exposure to loss.

VRDOs and Participating VRDOs

      VRDOs are tax exempt obligations that contain a floating or variable
interest rate adjustment formula and right of demand on the part of the holder
thereof to receive payment of the unpaid principal balance plus accrued
interest upon a short notice period not to exceed seven days. There is,
however, the possibility that because of default or insolvency the demand
feature of VRDOs and Participating VRDOs may not be honored. The interest
rates are adjustable at intervals (ranging from daily to up to one year) to
some prevailing market rate for similar investments, such adjustment formula
being calculated to maintain the market value of the VRDOs, at approximately
the par value of the VRDOs on the adjustment date. The adjustments typically
are based upon the Public Securities Association Index or some other
appropriate interest rate adjustment index. The Fund may invest in all types
of tax exempt instruments currently outstanding or to be issued in the future
which satisfy its short term maturity and quality standards.

      Participating VRDOs provide the Fund with a specified undivided interest
(up to 100%) of the underlying obligation and the right to demand payment of
the unpaid principal balance plus accrued interest on the Participating VRDOs
from the financial institution upon a specified number of days' notice, not to
exceed seven days. In addition, the Participating VRDO is backed by an
irrevocable letter of credit or guaranty of the financial institution. The
Fund would have an undivided interest in the underlying obligation and thus
participate on the same basis as the financial institution in such obligation
except that the financial institution typically retains fees out of the
interest paid on the obligation for servicing the obligation, providing the
letter of credit and issuing the repurchase commitment. The Fund has been
advised by its counsel that the Fund should be entitled to treat the income
received on Participating VRDOs as interest from tax exempt obligations as
long as the Fund does not invest more than 20% of its total assets in such
investments and certain other conditions are met. It is contemplated that the
Fund will not invest more than 20% of its assets in Participating VRDOs.

      VRDOs that contain an unconditional right of demand to receive payment
of the unpaid principal balance plus accrued interest on a notice period
exceeding seven days may be deemed to be illiquid securities. The Directors
may adopt guidelines and delegate to the Investment Adviser the daily function
of determining and monitoring liquidity of such VRDOs. The Directors, however,
will retain sufficient oversight and will be ultimately responsible for such
determinations.

      The Temporary Investments, VRDOs and Participating VRDOs in which the
Fund may invest will be in the following rating categories at the time of
purchase: MIG-1/VMIG-1 through MIG-3/VMIG-3 for notes and VRDOs and Prime-1
through Prime-3 for commercial paper (as determined by Moody's), SP-1 through
SP-2 for notes and A-1 through A-3 for VRDOs and commercial paper (as
determined by S&P), or F-1 through F-3 for notes, VRDOs and commercial paper
(as determined by Fitch). Temporary Investments, if not rated, must be of
comparable quality in the opinion of the Investment Adviser. In addition, the
Fund reserves the right to invest temporarily a greater portion of its assets
in Temporary Investments for defensive purposes, when, in the judgment of the
Investment Adviser, market conditions warrant.

Repurchase Agreements

      The Fund may invest in securities pursuant to repurchase agreements.
Repurchase agreements may be entered into only with a member bank of the
Federal Reserve System or a primary dealer or an affiliate thereof, in U.S.
Government securities. Under such agreements, the bank or primary dealer or an
affiliate thereof agrees, upon entering into the contract, to repurchase the
security at a mutually agreed upon time and price, thereby determining the
yield during the term of the agreement. This results in a fixed rate of return
insulated from market fluctuations during such period. In repurchase
agreements, the prices at which the trades are conducted do not reflect
accrued interest on the underlying obligations. Such agreements usually cover
short periods, such as under one week.



                                      29
<PAGE>

Repurchase agreements may be construed to be collateralized loans by the
purchaser to the seller secured by the securities transferred to the
purchaser. In a repurchase agreement, the Fund will require the seller to
provide additional collateral if the market value of the securities falls
below the repurchase price at any time during the term of the repurchase
agreement. In the event of default by the seller under a repurchase agreement
construed to be a collateralized loan, the underlying securities are not owned
by the Fund but only constitute collateral for the seller's obligation to pay
the repurchase price. Therefore, the Fund may suffer time delays and incur
costs or possible losses in connection with the disposition of the collateral.
In the event of a default under such a repurchase agreement, instead of the
contractual fixed rate of return, the rate of return to the Fund shall be
dependent upon intervening fluctuations of the market value of such security
and the accrued interest on the security. In such event, the Fund would have
rights against the seller for breach of contract with respect to any losses
arising from market fluctuations following the failure of the seller to
perform.

      In general, for Federal income tax purposes, repurchase agreements are
treated as collateralized loans secured by the securities "sold." Therefore,
amounts earned under such agreements will not be considered tax exempt
interest. The treatment of purchase and sales contracts is less certain.

Borrowings

      The Fund is authorized to borrow money in amounts of up to 5% of the
value of its total assets at the time of such borrowings; provided, however,
that the Fund is authorized to borrow moneys in amounts of up to 33?% of the
value of its total assets at the time of such borrowings to finance the
repurchase of its own common stock pursuant to tender offers or otherwise to
redeem or repurchase shares of preferred stock. Borrowings by the Fund
(commonly known, as with the issuance of preferred stock, as "leveraging")
create an opportunity for greater total return since, for example, the Fund
will not be required to sell portfolio securities to repurchase or redeem
shares but, at the same time, increase exposure to capital risk. In addition,
borrowed funds are subject to interest costs that may offset or exceed the
return earned on the borrowed funds.

                              DESCRIPTION OF AMPS

      Certain of the capitalized terms used herein not otherwise defined in
this prospectus have the meaning provided in the Glossary at the back of this
prospectus.

General

      The Series C AMPS will be shares of preferred stock that entitle their
holders to receive dividends when, as and if declared by the Board of
Directors, out of funds legally available therefor, at a rate per annum that
may vary for the successive Dividend Periods. After the Initial Dividend
Period, each Subsequent Dividend Period for the Series C AMPS generally will
be a 7-Day Dividend Period; provided however, that, prior to any Auction, the
Fund may elect, subject to certain limitations described herein, upon giving
notice to holders thereof, a special dividend period of up to five years (a
"Special Dividend Period"). The Applicable Rate for a particular Dividend
Period will be determined by an Auction conducted on the Business Day before
the start of such Dividend Period. Beneficial Owners and Potential Beneficial
Owners of shares of AMPS may participate in Auctions therefor, although,
except in the case of a Special Dividend Period of more than 28 days,
Beneficial Owners desiring to continue to hold all of their shares of AMPS
regardless of the Applicable Rate resulting from Auctions need not
participate. For an explanation of Auctions and the method of determining the
Applicable Rate, see "The Auction" herein and in the statement of additional
information.

      The Fund has outstanding 4,400 shares of two other series of Auction
Market Preferred Stock, each with a liquidation preference of $25,000 per
share, plus accumulated but unpaid dividends, for an aggregate initial
liquidation preference of $110,000,000 (the "Other AMPS"). The Other AMPS are
as follows: 2,200 shares of Auction Market Preferred Stock, Series A and 2,200
shares of Auction Market Preferred Stock, Series B. The Series C AMPS offered
hereby rank on a parity with the Other AMPS with respect to dividends and
liquidation preference. The terms of the shares of Other AMPS are
substantially the same as the terms of the shares of AMPS described below.



                                      30
<PAGE>

      The following is a brief description of the terms of the shares of AMPS.
This description does not purport to be complete and is subject to and
qualified in its entirety by reference to the Fund's Charter and Articles
Supplementary of the AMPS, including the provisions thereof establishing the
AMPS. The Fund's Charter and the form of Articles Supplementary of the AMPS
establishing the terms of the AMPS have been filed as exhibits to the
Registration Statement of which this prospectus is a part.

Dividends

      General. The holders of shares of AMPS will be entitled to receive,
when, as and if declared by the Board of Directors of the Fund, out of funds
legally available therefor, cumulative cash dividends on their shares, at the
Applicable Rate determined as set forth below under "Determination of Dividend
Rate," payable on the respective dates set forth below. Dividends on the
shares of AMPS so declared and payable shall be paid (i) in preference to and
in priority over any dividends so declared and payable on the Fund's common
stock, and (ii) to the extent permitted under the Code, and to the extent
available, out of net tax exempt income earned on the Fund's investments.
Generally, dividends on shares of AMPS, to the extent that they are derived
from interest paid on Municipal Bonds, will be exempt from Federal income
taxes, subject to possible application of the alternative minimum tax. See
"Taxes."

      Dividends on the shares of AMPS will accumulate from the date on which
the Fund originally issues the shares of AMPS (the "Date of Original Issue")
and will be payable on the dates described below. Dividends on shares of AMPS
with respect to the Initial Dividend Period shall be payable on the Initial
Dividend Payment Date. Following the Initial Dividend Payment Date for the
AMPS, dividends on the AMPS will be payable, at the option of the Fund, either
(i) with respect to any 7-Day Dividend Period and any Short Term Dividend
Period of 35 or fewer days, on the day next succeeding the last day thereof or
(ii) with respect to any Short Term Dividend Period of more than 35 days and
with respect to any Long Term Dividend Period, monthly on the first Business
Day of each calendar month during such Short Term Dividend Period or Long Term
Dividend Period and on the day next succeeding the last day thereof (each such
date referred to in clause (i) or (ii) being referred to herein as a "Normal
Dividend Payment Date"), except that if such Normal Dividend Payment Date is
not a Business Day, the Dividend Payment Date shall be the first Business Day
next succeeding such Normal Dividend Payment Date. Thus, following the Initial
Dividend Payment Date for AMPS, dividends generally will be payable (in the
case of Dividend Periods which are not Special Dividend Periods) on each
succeeding [ ] in the case of the Series C AMPS. Although any particular
Dividend Payment Date may not occur on the originally scheduled date because
of the exceptions discussed above, the next succeeding Dividend Payment Date,
subject to such exceptions, will occur on the next following originally
scheduled date. If for any reason a Dividend Payment Date cannot be fixed as
described above, then the Board of Directors shall fix the Dividend Payment
Date. The Board of Directors by resolution prior to authorization of a
dividend by the Board of Directors may change a Dividend Payment Date if such
change does not adversely affect the contract rights of the holders of shares
of AMPS set forth in the Charter. The Initial Dividend Period, 7-Day Dividend
Periods and Special Dividend Periods are hereinafter sometimes referred to as
"Dividend Periods." Each dividend payment date determined as provided above is
hereinafter referred to as a "Dividend Payment Date."

      Prior to each Dividend Payment Date, the Fund is required to deposit
with the Auction Agent sufficient funds for the payment of declared dividends.
The Fund does not intend to establish any reserves for the payment of
dividends.

      Each dividend will be paid to the record holder of the AMPS, which
holder is expected to be the nominee of the Securities Depository. See "The
Auction--Securities Depository." The Securities Depository will credit the
accounts of the Agent Members of the Existing Holders in accordance with the
Securities Depository's normal procedures which provide for payment in
same-day funds. The Agent Member of an Existing Holder will be responsible for
holding or disbursing such payments on the applicable Dividend Payment Date to
such Existing Holder in accordance with the instructions of such Existing
Holder. Dividends in arrears for any past Dividend Period may be declared and
paid at any time, without reference to any regular Dividend Payment Date, to
the nominee of the Securities Depository. Any dividend payment made on shares
of AMPS first shall be credited against the earliest declared but unpaid
dividends accumulated with respect to such shares.



                                      31
<PAGE>

      Holders of shares of AMPS will not be entitled to any dividends, whether
payable in cash, property or stock, in excess of full cumulative dividends
except as described below under "--Additional Dividends" in this prospectus
and under "Description of AMPS--Dividends--Non-Payment Period; Late Charge" in
the statement of additional information. No interest will be payable in
respect of any dividend payment or payments on the shares of AMPS that may be
in arrears.

      The amount of cash dividends per share of the AMPS payable (if declared)
on the Initial Dividend Payment Date, and on each Dividend Payment Date of
each 7-Day Dividend Period and each Short Term Dividend Period, shall be
computed by multiplying the Applicable Rate for such Dividend Period by a
fraction, the numerator of which will be the number of days in such Dividend
Period or part thereof that such share was outstanding and for which dividends
are payable on such Dividend Payment Date and the denominator of which will be
365, multiplying the amount so obtained by $25,000, and rounding the amount so
obtained to the nearest cent. During any Long Term Dividend Period, the amount
of cash dividends per share of AMPS payable (if declared) on any Dividend
Payment Date shall be computed by multiplying the Applicable Rate for such
Dividend Period by a fraction, the numerator of which will be such number of
days in such part of such Dividend Period that such share was outstanding and
for which dividends are payable on such Dividend Payment Date and the
denominator of which will be 360, multiplying the amount so obtained by
$25,000, and rounding the amount so obtained to the nearest cent.

      Notification of Dividend Period. With respect to each Dividend Period
that is a Special Dividend Period, the Fund, at its sole option and to the
extent permitted by law, by telephonic and written notice (a "Request for
Special Dividend Period") to the Auction Agent and to each Broker-Dealer, may
request that the next succeeding Dividend Period for the AMPS will be a number
of days (other than seven), evenly divisible by seven, and not fewer than
seven nor more than 364 in the case of a Short Term Dividend Period or one
whole year or more but not greater than five years in the case of a Long Term
Dividend Period, specified in such notice, provided that the Fund may not give
a Request for Special Dividend Period (and any such request shall be null and
void) unless, for any Auction occurring after the initial Auction, Sufficient
Clearing Bids were made in the last occurring Auction and unless full
cumulative dividends and any amounts due with respect to redemptions, and any
Additional Dividends payable prior to such date have been paid in full. Such
Request for Special Dividend Period, in the case of a Short Term Dividend
Period, shall be given on or prior to the second Business Day but not more
than seven Business Days prior to an Auction Date for the AMPS and, in the
case of a Long Term Dividend Period, shall be given on or prior to the second
Business Day but not more than 28 days prior to an Auction Date for the AMPS.
Upon receiving such Request for Special Dividend Period, the Broker-Dealers
jointly shall determine whether, given the factors set forth below, it is
advisable that the Fund issue a Notice of Special Dividend Period for the AMPS
as contemplated by such Request for Special Dividend Period and the Optional
Redemption Price of the AMPS during such Special Dividend Period and the
Specific Redemption Provisions and shall give the Fund written notice (a
"Response") of such determination by no later than the second Business Day
prior to such Auction Date. In the event the Response indicates that it is
advisable that the Fund give a notice of a Special Dividend Period for the
AMPS, the Fund, by no later than the second Business Day prior to such Auction
Date may give a notice (a "Notice of Special Dividend Period") to the Auction
Agent, the Securities Depository and each Broker-Dealer. See "Description of
AMPS--Dividends--Notification of Dividend Period" in the statement of
additional information for a detailed description of these procedures.

      Determination of Dividend Rate. The dividend rate on shares of the AMPS
during the period from and including the Date of Original Issue for the Series
C AMPS to but excluding the Initial Dividend Payment Date (the "Initial
Dividend Period") with respect to the Series C AMPS will be the rate per annum
set forth above under "Prospectus Summary--Dividends and Dividend Periods."
Commencing on the Initial Dividend Payment Date for the Series C AMPS, the
Applicable Rate on the Series C AMPS for each Subsequent Dividend Period,
which Subsequent Dividend Period shall be a period commencing on and including
a Dividend Payment Date and ending on and including the calendar day prior to
the next Dividend Payment Date (or calendar day prior to the last Dividend
Payment Date in a Dividend Period if there is more than one Dividend Payment
Date), shall be equal to the rate per annum that results from the Auction with
respect to such Subsequent Dividend Period. The Initial Dividend Period and
Subsequent Dividend Period for the AMPS is referred to herein as a "Dividend
Period." Cash dividends shall be calculated as set forth above under
"Dividends--General."

      Restrictions on Dividends and Other Payments. Under the 1940 Act, the
Fund may not declare dividends or make other distributions on shares of common
stock or purchase any such shares if, at the time of the declaration,



                                      32
<PAGE>

distribution or purchase, as applicable (and after giving effect thereto),
asset coverage (as defined in the 1940 Act) with respect to the outstanding
shares of AMPS (and Other AMPS) would be less than 200% (or such other
percentage as in the future may be required by law). The Fund estimates that,
based on the composition of its portfolio at April 30, 2005, asset coverage
with respect to shares of AMPS would be approximately 280% representing
approximately 36% of the Fund's capital and 56% of the Fund's common stock
equity immediately after the issuance of the shares of AMPS offered hereby.
Under the Code, the Fund, among other things, must distribute at least 90% of
its investment company taxable income each year in order to maintain its
qualification for tax treatment as a regulated investment company. The
foregoing limitations on dividends, distributions and purchases under certain
circumstances may impair the Fund's ability to maintain such qualification.
See "Taxes" in the statement of additional information.

      Upon any failure to pay dividends on shares of AMPS for two years or
more, the holders of the shares of AMPS will acquire certain additional voting
rights. See "Voting Rights" below. Such rights shall be the exclusive remedy
of the holders of shares of AMPS upon any failure to pay dividends on shares
of the Fund.

      Additional Dividends. If the Fund retroactively allocates any net
capital gain or other income subject to regular Federal income taxes to shares
of AMPS without having given advance notice thereof to the Auction Agent as
described under "The Auction--Auction Procedures--Auction Date; Advance Notice
of Allocation of Taxable Income; Inclusion of Taxable Income in Dividends"
below, which may only happen when such allocation is made as a result of the
redemption of all or a portion of the outstanding shares of AMPS or the
liquidation of the Fund (the amount of such allocation referred to herein as a
"Retroactive Taxable Allocation"), the Fund, within 90 days (and generally
within 60 days) after the end of the Fund's fiscal year for which a
Retroactive Taxable Allocation is made, will provide notice thereof to the
Auction Agent and to each holder of shares (initially Cede as nominee of the
Securities Depository) during such fiscal year at such holder's address as the
same appears or last appeared on the stock books of the Fund. The Fund, within
30 days after such notice is given to the Auction Agent, will pay to the
Auction Agent (who then will distribute to such holders of shares of AMPS),
out of funds legally available therefor, an amount equal to the aggregate
Additional Dividend (as defined below) with respect to all Retroactive Taxable
Allocations made to such holders during the fiscal year in question.

      An "Additional Dividend" means payment to a present or former holder of
shares of AMPS of an amount which, when taken together with the aggregate
amount of Retroactive Taxable Allocations made to such holder with respect to
the fiscal year in question, would cause such holder's dividends in dollars
(after Federal income tax consequences) from the aggregate of both the
Retroactive Taxable Allocations and the Additional Dividend to be equal to the
dollar amount of the dividends which would have been received by such holder
if the amount of the aggregate Retroactive Taxable Allocations had been
excludable from the gross income of such holder. Such Additional Dividend
shall be calculated (i) without consideration being given to the time value of
money; (ii) assuming that no holder of shares of AMPS is subject to the
Federal alternative minimum tax with respect to dividends received from the
Fund; and (iii) assuming that each Retroactive Taxable Allocation would be
taxable in the hands of each holder of shares of AMPS at the greater of: (a)
the maximum marginal regular Federal individual income tax rate applicable to
ordinary income or capital gains depending on the taxable character of the
distribution (including any surtax); or (b) the maximum marginal regular
Federal corporate income tax rate applicable to ordinary income or capital
gains depending on the taxable character of the distribution (disregarding in
both (a) and (b) the effect of any state or local taxes and the phase out of,
or provision limiting, personal exemptions, itemized deductions, or the
benefit of lower tax brackets). Although the Fund generally intends to
designate any Additional Dividend as an exempt-interest dividend to the extent
permitted by applicable law, it is possible that all or a portion of any
Additional Dividend will be taxable to the recipient thereof. See "Taxes" in
the statement of additional information. The Fund will not pay a further
Additional Dividend with respect to any taxable portion of an Additional
Dividend.

      If the Fund does not give advance notice of the amount of taxable income
to be included in a dividend on shares of AMPS in the related Auction, the
Fund may include such taxable income in a dividend on shares of AMPS if it
increases the dividend by an additional amount calculated as if such income
were a Retroactive Taxable Allocation and the additional amount were an
Additional Dividend and notifies the Auction Agent of such inclusion at least
five Business Days prior to the applicable Dividend Payment Date. See "The
Auction-- Auction Procedures--Auction Date; Advance Notice of Allocation of
Taxable Income; Inclusion of Taxable Income in Dividends" below.



                                      33

Asset Maintenance

      The Fund will be required to satisfy two separate asset maintenance
requirements under the terms of the Articles Supplementary. These requirements
are summarized below.

      1940 Act AMPS Asset Coverage. The Fund will be required under the
Articles Supplementary to maintain, with respect to shares of AMPS, as of the
last Business Day of each month in which any shares of AMPS are outstanding,
asset coverage of at least 200% with respect to senior securities that are
stock, including the shares of AMPS and Other AMPS (or such other asset
coverage as in the future may be specified in or under the 1940 Act as the
minimum asset coverage for senior securities that are stock of a closed-end
investment company as a condition of paying dividends on its common stock)
("1940 Act AMPS Asset Coverage"). If the Fund fails to maintain 1940 Act AMPS
Asset Coverage and such failure is not cured as of the last Business Day of
the following month (the "1940 Act Cure Date"), the Fund will be required
under certain circumstances to redeem certain of the shares of AMPS. See
"Redemption" below.

      Based upon the composition of the Fund's portfolio at April 30, 2005,
the 1940 Act AMPS Asset Coverage immediately following the issuance of AMPS
offered hereby (after giving effect to the deduction of the underwriting
discount and offering expenses for the shares of AMPS) will be computed as
follows:

           Value of Fund assets less
          liabilities not constituting
               senior securities               =     $349,933,260    =      280%
     --------------------------------------        ----------------
         Senior securities representing              $125,000,000
         indebtedness plus liquidation
          value of the shares of AMPS

      AMPS Basic Maintenance Amount. So long as shares of AMPS are
outstanding, the Fund will be required under the Articles Supplementary to
maintain as of the last Business Day of each week (a "Valuation Date") Moody's
Eligible Assets and S&P Eligible Assets each having in the aggregate a
Discounted Value at least equal to the AMPS Basic Maintenance Amount. The AMPS
Basic Maintenance Amount includes the sum of (i) the aggregate liquidation
value of AMPS and Other AMPS then outstanding and (ii) certain accrued and
projected payment obligations of the Fund. See "Description of AMPS--Asset
Maintenance--AMPS Basic Maintenance Amount" in the statement of additional
information. If the Fund fails to meet such requirement as of any Valuation
Date and such failure is not cured on or before the sixth Business Day after
such Valuation Date (the "AMPS Basic Maintenance Cure Date"), the Fund will be
required under certain circumstances to redeem certain of the shares of AMPS.
Upon any failure to maintain the required Discounted Value, the Fund will use
its best efforts to alter the composition of its portfolio to reattain a
Discounted Value at least equal to the AMPS Basic Maintenance Amount on or
prior to the AMPS Basic Maintenance Cure Date. See "Redemption" herein and in
the statement of additional information.

Redemption

      Optional Redemption. To the extent permitted under the 1940 Act and
under Maryland law, upon giving a Notice of Redemption, as provided in the
statement of additional information, the Fund, at its option, may redeem
shares of AMPS, in whole or in part, out of funds legally available therefor,
at the Optional Redemption Price per share on any Dividend Payment Date;
provided that no share of AMPS may be redeemed at the option of the Fund
during (a) the Initial Dividend Period with respect to such share or (b) a
Non-Call Period to which such share is subject. "Optional Redemption Price"
means $25,000 per share of AMPS plus an amount equal to accumulated but unpaid
dividends (whether or not earned or declared) to the date fixed for redemption
plus any applicable redemption premium, if any, attributable to the
designation of a Premium Call Period. In addition, holders of AMPS may be
entitled to receive Additional Dividends in the event of redemption of such
AMPS to the extent provided herein. See "Dividends--Additional Dividends." The
Fund has the authority to redeem the AMPS for any reason and may redeem all or
part of the outstanding shares of AMPS if it anticipates that the Fund's
leveraged capital structure will result in a lower rate of return to holders
of common stock for any significant period of time than that obtainable if the
common stock were unleveraged.



                                      34
<PAGE>

      Mandatory Redemption. The Fund will be required to redeem, out of funds
legally available therefor, at the Mandatory Redemption Price per share,
shares of AMPS to the extent permitted under the 1940 Act and Maryland law, on
a date fixed by the Board of Directors, if the Fund fails to maintain Moody's
Eligible Assets and S&P Eligible Assets each with an aggregate Discounted
Value equal to or greater than the AMPS Basic Maintenance Amount or to satisfy
the 1940 Act AMPS Asset Coverage and such failure is not cured on or before
the AMPS Basic Maintenance Cure Date or the 1940 Act Cure Date (herein
collectively referred to as a "Cure Date"), as the case may be. "Mandatory
Redemption Price" means $25,000 per share of AMPS plus an amount equal to
accumulated but unpaid dividends (whether or not earned or declared) to the
date fixed for redemption. In addition, holders of AMPS may be entitled to
receive Additional Dividends in the event of redemption of such AMPS to the
extent provided herein. See "Dividends--Additional Dividends."

      For a discussion of the allocation procedures to be used if fewer than
all of the outstanding shares of AMPS are to be redeemed and for a discussion
of other redemption procedures, see "Description of AMPS-- Redemption" in the
statement of additional information.

Liquidation Rights

      Upon any liquidation, dissolution or winding up of the Fund, whether
voluntary or involuntary, the holders of shares of AMPS will be entitled to
receive, out of the assets of the Fund available for distribution to
stockholders, before any distribution or payment is made upon any shares of
common stock or any other capital stock of the Fund ranking junior in right of
payment upon liquidation of AMPS, $25,000 per share together with the amount
of any dividends accumulated but unpaid (whether or not earned or declared)
thereon to the date of distribution, and after such payment the holders of
AMPS will be entitled to no other payments except for Additional Dividends. If
such assets of the Fund shall be insufficient to make the full liquidation
payment on the outstanding shares of AMPS and liquidation payments on any
other outstanding class or series of preferred stock of the Fund ranking on a
parity with the AMPS as to payment upon liquidation, including the Other AMPS,
then such assets will be distributed among the holders of such shares of AMPS
and the holders of shares of such other class or series, including the Other
AMPS, ratably in proportion to the respective preferential amounts to which
they are entitled. After payment of the full amount of liquidation
distribution to which they are entitled, the holders of AMPS will not be
entitled to any further participation in any distribution of assets by the
Fund. A consolidation, merger or share exchange of the Fund with or into any
other entity or entities or a sale, whether for cash, shares of stock,
securities or properties, of all or substantially all or any part of the
assets of the Fund shall not be deemed or construed to be a liquidation,
dissolution or winding up of the Fund.

Voting Rights

      Except as otherwise indicated in this prospectus and the statement of
additional information and except as otherwise required by applicable law,
holders of shares of AMPS will be entitled to one vote per share on each
matter submitted to a vote of stockholders of the Fund and will vote together
with holders of shares of Other AMPS and holders of shares of common stock as
a single class.

      The 1940 Act and the Articles Supplementary require that the holders of
preferred stock, including the AMPS and Other AMPS, voting as a separate
class, have the rights to elect two of the Fund's Directors at all times and
to elect a majority of the Directors at any time that two full years'
dividends on the AMPS (and Other AMPS) are unpaid. The holders of AMPS (and
Other AMPS) will vote as a separate class or classes on certain other matters
as required under the Articles Supplementary, the 1940 Act and Maryland law.
In addition, the Series C AMPS (and Other AMPS) may vote as a separate series
under certain circumstances. See "Description of AMPS--Voting Rights" in the
statement of additional information.

                                  THE AUCTION

      Certain of the capitalized terms used herein not otherwise defined in
this prospectus have the meaning provided in the Glossary at the back of this
prospectus.



                                      35

General

      Holders of the shares of the Series C AMPS will be entitled to receive
cumulative cash dividends on their shares when, as and if declared by the
Board of Directors of the Fund, out of funds legally available therefor, on
the Initial Dividend Payment Date with respect to the Initial Dividend Period
and, thereafter, on each Dividend Payment Date with respect to a Subsequent
Dividend Period (generally a period of seven days, subject to certain
exceptions set forth under "Description of AMPS--Dividends--General") at the
rate per annum equal to the Applicable Rate for each such Dividend Period.

      The provisions of the Articles Supplementary establishing the terms of
the Series C AMPS offered hereby will provide that the Applicable Rate for the
shares of AMPS for each Dividend Period after the Initial Dividend Period
therefor will be equal to the rate per annum that the Auction Agent advises
has resulted on the Business Day preceding the first day of such Dividend
Period due to implementation of the auction procedures set forth in the
Articles Supplementary (the "Auction Procedures") in which persons determine
to hold or offer to purchase or sell shares of AMPS. The Auction Procedures
are attached as Appendix C to the statement of additional information.

      Each periodic operation of such procedures with respect to the shares of
AMPS is referred to hereinafter as an "Auction." If, however, the Fund should
fail to pay or duly provide for the full amount of any dividend on shares of
AMPS or the redemption price of shares of AMPS called for redemption, the
Applicable Rate for shares of AMPS will be determined as set forth under
"Description of AMPS--Dividends--Non-Payment Period; Late Charge" in the
statement of additional information.

      Auction Agent Agreement. The Fund has entered into an agreement with The
Bank of New York (together with any successor bank or trust company or other
entity entering into a similar agreement with this Fund, the "Auction Agent")
(the "Auction Agent Agreement"), which provides, among other things, that the
Auction Agent will follow the Auction Procedures for the purpose of
determining the Applicable Rate for the AMPS. The Fund will pay the Auction
Agent compensation for its services under the Auction Agent Agreement.

      Broker-Dealer Agreements. The Auction Agent has entered into agreements
with Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") and
more than [ ] other broker-dealers and may enter into similar agreements
(collectively, the "Broker-Dealer Agreements") with one or more other
broker-dealers (collectively, the "Broker-Dealers") selected by the Fund,
which provide for the participation of such Broker-Dealers in Auctions.
Merrill Lynch is an affiliate of the Investment Adviser in that they share a
common parent, Merrill Lynch & Co., Inc.

      Securities Depository. The Depository Trust Company initially will act
as the Securities Depository for the Agent Members with respect to the shares
of Series C AMPS. One or more registered certificates for all of the shares of
the Series C AMPS initially will be registered in the name of Cede, as nominee
of the Securities Depository. The certificate will bear a legend to the effect
that such certificate is issued subject to the provisions restricting
transfers of shares of AMPS to which it relates contained in the Articles
Supplementary. Cede initially will be the holder of record of all shares of
AMPS, and Beneficial Owners will not be entitled to receive certificates
representing their ownership interest in such shares. The Securities
Depository will maintain lists of its participants and will maintain the
positions (ownership interests) of shares of AMPS held by each Agent Member,
whether as the Beneficial Owner thereof for its own account or as nominee for
the Beneficial Owner thereof. Payments made by the Fund to holders of AMPS
will be duly made by making payments to the nominee of the Securities
Depository.

Auction Procedures

      The following is a brief discussion of the procedures to be used in
conducting Auctions. This summary is qualified by reference to the Auction
Procedures set forth in Appendix C to the statement of additional information.
The Settlement Procedures to be used with respect to Auctions are set forth in
Appendix B to the statement of additional information.

      Auction Date; Advance Notice of Allocation of Taxable Income; Inclusion
of Taxable Income in Dividends. An Auction to determine the Applicable Rate
for the shares of the Series C AMPS offered hereby for each Dividend



                                      36
<PAGE>

Period (other than the Initial Dividend Period therefor) will be held on the
first Business Day (as hereinafter defined) preceding the first day of such
Dividend Period, which first day is also a Dividend Payment Date for the
preceding Dividend Period (the date of each Auction being referred to herein
as an "Auction Date"). "Business Day" means a day on which The New York Stock
Exchange (the "NYSE") is open for trading and which is not a Saturday, Sunday
or other day on which banks in the City of New York are authorized or
obligated by law to close. Auctions for shares of the Series C AMPS for
Dividend Periods after the Initial Dividend Period normally will be held every
[    ] after the preceding Dividend Payment Date, and each subsequent Dividend
Period normally will begin on the following [    ] (also a Dividend Payment
Date). The Auction Date and the first day of the related Dividend Period (both
of which must be Business Days) need not be consecutive calendar days. For
example, in most cases, if the [    ] that normally would be an Auction Date for
the Series C AMPS is not a Business Day, then such Auction Date will be the
preceding [    ] and the first day of the related Dividend Period will continue
to be the following [    ]. See "Description of AMPS--Dividends" for information
concerning the circumstances under which a Dividend Payment Date may fall on a
date other than the days specified above, which may affect the Auction Date.

      Except as noted below, whenever the Fund intends to include any net
capital gain or other income subject to regular Federal income taxes in any
dividend on shares of AMPS, the Fund will notify the Auction Agent of the
amount to be so included at least five Business Days prior to the Auction Date
on which the Applicable Rate for such dividend is to be established. Whenever
the Auction Agent receives such notice from the Fund, in turn it will notify
each Broker-Dealer, who, on or prior to such Auction Date, in accordance with
its Broker-Dealer Agreement, will notify its customers who are Beneficial
Owners and Potential Beneficial Owners believed to be interested in submitting
an Order in the Auction to be held on such Auction Date. The Fund also may
include such income in a dividend on shares of AMPS without giving advance
notice thereof if it increases the dividend by an additional amount calculated
as if such income were a Retroactive Taxable Allocation and the additional
amount were an Additional Dividend; provided that the Fund will notify the
Auction Agent of the additional amounts to be included in such dividend at
least five Business Days prior to the applicable Dividend Payment Date. See
"Description of AMPS--Dividends--Additional Dividends" above.

      Orders by Beneficial Owners, Potential Beneficial Owners, Existing
Holders and Potential Holders. On or prior to each Auction Date:

            (a) each Beneficial Owner may submit to its Broker-Dealer by
      telephone a:

                  (i) Hold Order--indicating the number of outstanding shares,
            if any, of AMPS that such Beneficial Owner desires to continue to
            hold without regard to the Applicable Rate for the next Dividend
            Period for such shares;

                  (ii) Bid--indicating the number of outstanding shares, if
            any, of AMPS that such Beneficial Owner desires to continue to
            hold, provided that the Applicable Rate for the next Dividend
            Period for such shares is not less than the rate per annum then
            specified by such Beneficial Owner; and/or

                  (iii) Sell Order--indicating the number of outstanding
            shares, if any, of AMPS that such Beneficial Owner offers to sell
            without regard to the Applicable Rate for the next Dividend Period
            for such shares; and

            (b) Broker-Dealers will contact customers who are Potential
      Beneficial Owners of shares of AMPS to determine whether such Potential
      Beneficial Owners desire to submit Bids indicating the number of shares
      of AMPS which they offer to purchase provided that the Applicable Rate
      for the next Dividend Period for such shares is not less than the rates
      per annum specified in such Bids.

      The communication by a Beneficial Owner or Potential Beneficial Owner to
a Broker-Dealer and the communication by a Broker-Dealer, whether or not
acting for its own account, to the Auction Agent of the foregoing information
is hereinafter referred to as an "Order" and collectively as "Orders." A
Beneficial Owner or a Potential Beneficial Owner placing an Order, including a
Broker-Dealer acting in such capacity for its own account, is hereinafter
referred to as a "Bidder" and collectively as "Bidders." Any Order submitted
by a Beneficial Owner or a



                                      37
<PAGE>

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

      In an Auction, a Beneficial Owner may submit different types of Orders
with respect to shares of AMPS then held by such Beneficial Owner, as well as
Bids for additional shares of AMPS. For information concerning the priority
given to different types of Orders placed by Beneficial Owners, see
"Submission of Orders by Broker-Dealers to Auction Agent" below.

      The Maximum Applicable Rate for shares of AMPS will be the higher of (A)
the Applicable Percentage of the Reference Rate or (B) the Applicable Spread
plus the Reference Rate. The Auction Agent will round each applicable Maximum
Applicable Rate to the nearest one-thousandth (0.001) of one percent per
annum, with any such number ending in five ten-thousandths of one percent
being rounded upwards to the nearest one-thousandth (0.001) of one percent.
The Auction Agent will not round the applicable Reference Rate as part of its
calculation of the Maximum Applicable Rate.

      The Maximum Applicable Rate for shares of AMPS will depend on the credit
rating or ratings assigned to such shares. The Applicable Percentage and the
Applicable Spread will be determined based on (i) the lower of the credit
rating or ratings assigned on such date to such shares by Moody's and S&P (or
if Moody's or S&P or both shall not make such rating available, the equivalent
of either or both of such ratings by a Substitute Rating Agency or two
Substitute Rating Agencies or, in the event that only one such rating shall be
available, such rating) and (ii) whether the Fund has provided notification to
the Auction Agent prior to the Auction establishing the Applicable Rate for
any dividend that net capital gain or other taxable income will be included in
such dividend on shares of AMPS as follows:

</TABLE>

      There is no minimum Applicable Rate in respect of any Dividend Period.

      The Applicable Percentage and the Applicable Spread as so determined may
be further subject to upward but not downward adjustment in the discretion of
the Board of Directors of the Fund after consultation with the Broker-Dealers,
provided that immediately following any such increase, the Fund would be in
compliance with the AMPS Basic Maintenance Amount. The Fund will take all
reasonable action necessary to enable either S&P or Moody's, or both to
provide a rating for the AMPS, subject to the Fund's ability to terminate
compliance with the rating agency guidelines as discussed under "Rating Agency
Guidelines." If either S&P or Moody's, or both, shall not make such a rating
available, and subject to the Fund's ability to terminate compliance with the
rating agency guidelines discussed under "Rating Agency Guidelines," Merrill
Lynch or its affiliates and successors, after obtaining the Fund's approval,
will select another NRSRO (a "Substitute Rating Agency") or two other NRSROs
("Substitute Rating Agencies") to act as a Substitute Rating Agency or
Substitute Rating Agencies, as the case may be.

      Any Bid by a Beneficial Owner specifying a rate per annum higher than
the Maximum Applicable Rate will be treated as a Sell Order, and any Bid by a
Potential Beneficial Owner specifying a rate per annum higher than the Maximum
Applicable Rate will not be considered. See "Determination of Sufficient
Clearing Bids, Winning Bid Rate and Applicable Rate" and "Acceptance and
Rejection of Submitted Bids and Submitted Sell Orders and Allocation of
Shares."

      Neither the Fund nor the Auction Agent will be responsible for a
Broker-Dealer's failure to comply with the foregoing.



                                      38

      A Broker-Dealer also may hold AMPS in its own account as a Beneficial
Owner. A Broker-Dealer thus may submit Orders to the Auction Agent as a
Beneficial Owner or a Potential Beneficial Owner and therefore participate in
an Auction as an Existing Holder or Potential Holder on behalf of both itself
and its customers. Any Order placed with the Auction Agent by a Broker-Dealer
as or on behalf of a Beneficial Owner or a Potential Beneficial Owner will be
treated in the same manner as an Order placed with a Broker-Dealer by a
Beneficial Owner or a Potential Beneficial Owner. Similarly, any failure by a
Broker-Dealer to submit to the Auction Agent an Order in respect of any AMPS
held by it or its customers who are Beneficial Owners will be treated in the
same manner as a Beneficial Owner's failure to submit to its Broker-Dealer an
Order in respect of AMPS held by it, as described in the next paragraph.
Inasmuch as a Broker-Dealer participates in an Auction as an Existing Holder
or a Potential Holder only to represent the interests of a Beneficial Owner or
Potential Beneficial Owner, whether it be its customers or itself, all
discussion herein relating to the consequences of an Auction for Existing
Holders and Potential Holders also applies to the underlying beneficial
ownership interests represented thereby. For information concerning the
priority given to different types of Orders placed by Existing Holders, see
"Submission of Orders by Broker-Dealers to Auction Agent." Each purchase or
sale in an Auction will be settled on the Business Day next succeeding the
Auction Date at a price per share equal to $25,000. See "Notification of
Results; Settlement" below.

      If one or more Orders covering in the aggregate all of the outstanding
shares of AMPS held by a Beneficial Owner are not submitted to the Auction
Agent prior to the Submission Deadline, either because a Broker-Dealer failed
to contact such Beneficial Owner or otherwise, the Auction Agent shall deem a
Hold Order (in the case of an Auction relating to a Dividend Period which is
not a Special Dividend Period of more than 28 days) and a Sell Order (in the
case of an Auction relating to a Special Dividend Period of more than 28 days)
to have been submitted on behalf of such Beneficial Owner covering the number
of outstanding shares of AMPS held by such Beneficial Owner and not subject to
Orders submitted to the Auction Agent.

      If all of the outstanding shares of AMPS are subject to Submitted Hold
Orders, the Dividend Period next succeeding the Auction automatically shall be
the same length as the immediately preceding Dividend Period, and the
Applicable Rate for the next Dividend Period for all shares of AMPS will be
60% of the Reference Rate on the date of the applicable Auction (or 90% of
such rate if the Fund has provided notification to the Auction Agent prior to
the Auction establishing the Applicable Rate for any dividend that net capital
gain or other taxable income will be included in such dividend on shares of
AMPS).

      For the purposes of an Auction, shares of AMPS for which the Fund shall
have given notice of redemption and deposited moneys therefor with the Auction
Agent in trust or segregated in an account at the Fund's custodian bank for
the benefit of holders of AMPS to be redeemed and for payment to the Auction
Agent, as set forth under "Description of AMPS--Redemption" in the statement
of additional information, will not be considered as outstanding and will not
be included in such Auction. Pursuant to the Articles Supplementary of the
Fund, the Fund will be prohibited from reissuing and its affiliates (other
than Merrill Lynch) will be prohibited from transferring (other than to the
Fund) any shares of AMPS they may acquire. Neither the Fund nor any affiliate
of the Fund may submit an Order in any Auction, except that an affiliate of
the Fund that is a Broker-Dealer (i.e., Merrill Lynch) may submit an Order.

      Submission of Orders by Broker-Dealers to Auction Agent. Prior to 1:00
p.m., Eastern time, on each Auction Date, or such other time on the Auction
Date as may be specified by the Auction Agent (the "Submission Deadline"),
each Broker-Dealer will submit to the Auction Agent in writing or through a
mutually acceptable electronic means all Orders obtained by it for the Auction
to be conducted on such Auction Date, designating itself (unless otherwise
permitted by the Fund) as the Existing Holder or Potential Holder in respect
of the shares of AMPS subject to such Orders. Any Order submitted by a
Beneficial Owner or a Potential Beneficial Owner to its Broker-Dealer, or by a
Broker-Dealer to the Auction Agent, prior to the Submission Deadline on any
Auction Date, shall be irrevocable.

      If the rate per annum specified in any Bid contains more than three
figures to the right of the decimal point, the Auction Agent will round such
rate per annum up to the next highest one-thousandth (.001) of 1%.

      If one or more Orders of an Existing Holder are submitted to the Auction
Agent and such Orders cover in the aggregate more than the number of
outstanding shares of AMPS held by such Existing Holder, such Orders will be
considered valid in the following order of priority:



                                      39
<PAGE>

            (a) any Hold Order will be considered valid up to and including
      the number of outstanding shares of AMPS held by such Existing Holder,
      provided that if more than one Hold Order is submitted by such Existing
      Holder and the number of shares of AMPS subject to such Hold Orders
      exceeds the number of outstanding shares of AMPS held by such Existing
      Holder, the number of shares of AMPS subject to each of such Hold Orders
      will be reduced pro rata so that such Hold Orders, in the aggregate,
      will cover exactly the number of outstanding shares of AMPS held by such
      Existing Holder;

            (b) any Bids will be considered valid, in the ascending order of
      their respective rates per annum if more than one Bid is submitted by
      such Existing Holder, up to and including the excess of the number of
      outstanding shares of AMPS held by such Existing Holder over the number
      of outstanding shares of AMPS subject to any Hold Order referred to in
      clause (a) above (and if more than one Bid submitted by such Existing
      Holder specifies the same rate per annum and together they cover more
      than the remaining number of shares that can be the subject of valid
      Bids after application of clause (a) above and of the foregoing portion
      of this clause (b) to any Bid or Bids specifying a lower rate or rates
      per annum, the number of shares subject to each of such Bids will be
      reduced pro rata so that such Bids, in the aggregate, cover exactly such
      remaining number of outstanding shares); and the number of outstanding
      shares, if any, subject to Bids not valid under this clause (b) shall be
      treated as the subject of a Bid by a Potential Holder; and

            (c) any Sell Order will be considered valid up to and including
      the excess of the number of outstanding shares of AMPS held by such
      Existing Holder over the sum of the number of shares of AMPS subject to
      Hold Orders referred to in clause (a) above and the number of shares of
      AMPS subject to valid Bids by such Existing Holder referred to in clause
      (b) above; provided that, if more than one Sell Order is submitted by
      any Existing Holder and the number of shares of AMPS subject to such
      Sell Orders is greater than such excess, the number of shares of AMPS
      subject to each of such Sell Orders will be reduced pro rata so that
      such Sell Orders, in the aggregate, will cover exactly the number of
      shares of AMPS equal to such excess.

      If more than one Bid of any Potential Holder is submitted in any
Auction, each Bid submitted in such Auction will be considered a separate Bid
with the rate per annum and number of shares of AMPS therein specified.

      Determination of Sufficient Clearing Bids, Winning Bid Rate and
Applicable Rate. Not earlier than the Submission Deadline for each Auction,
the Auction Agent will assemble all Orders submitted or deemed submitted to it
by the Broker-Dealers (each such "Hold Order," "Bid" or "Sell Order" as
submitted or deemed submitted by a Broker-Dealer hereinafter being referred to
as a "Submitted Hold Order," a "Submitted Bid" or a "Submitted Sell Order," as
the case may be, or as a "Submitted Order") and will determine the excess of
the number of outstanding shares of AMPS over the number of outstanding shares
of AMPS subject to Submitted Hold Orders (such excess being referred to as the
"Available AMPS") and whether Sufficient Clearing Bids have been made in such
Auction. Sufficient Clearing Bids will have been made if the number of
outstanding shares of AMPS that are the subject of Submitted Bids of Potential
Holders with rates per annum not higher than the Maximum Applicable Rate
equals or exceeds the number of outstanding shares that are the subject of
Submitted Sell Orders (including the number of shares subject to Bids of
Existing Holders specifying rates per annum higher than the Maximum Applicable
Rate).

      If Sufficient Clearing Bids have been made, the Auction Agent will
determine the lowest rate per annum specified in the Submitted Bids (the
"Winning Bid Rate") which would result in the number of shares subject to
Submitted Bids specifying such rate per annum or a lower rate per annum being
at least equal to the Available AMPS. If Sufficient Clearing Bids have been
made, the Winning Bid Rate will be the Applicable Rate for the next Dividend
Period for all shares of AMPS then outstanding.

      If Sufficient Clearing Bids have not been made (other than because all
outstanding shares of AMPS are the subject of Submitted Hold Orders), the
Dividend Period next following the Auction automatically will be a 7-Day
Dividend Period in the case of the Series C AMPS, and the Applicable Rate for
such Dividend Period will be equal to the Maximum Applicable Rate.

      If Sufficient Clearing Bids have not been made, Beneficial Owners that
have Submitted Sell Orders will not be able to sell in the Auction all, and
may not be able to sell any, shares of AMPS subject to such Submitted Sell



                                      40
<PAGE>

Orders. See "Acceptance and Rejection of Submitted Bids and Submitted Sell
Orders and Allocation of Shares." Thus, under some circumstances, Beneficial
Owners may not have liquidity of investment.

      Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and
Allocation of Shares. Based on the determinations described under
"Determination of Sufficient Clearing Bids, Winning Bid Rate and Applicable
Rate" and subject to the discretion of the Auction Agent to round as described
below, Submitted Bids and Submitted Sell Orders will be accepted or rejected
in the order of priority set forth in the Auction Procedures with the result
that Existing Holders and Potential Holders of AMPS will sell, continue to
hold and/or purchase shares of AMPS as set forth below. Existing Holders that
submit or are deemed to have submitted Hold Orders will continue to hold the
shares of AMPS subject to such Hold Orders.

      If Sufficient Clearing Bids have been made:

            (a) each Existing Holder that placed a Submitted Bid specifying a
      rate per annum higher than the Winning Bid Rate or a Submitted Sell
      Order will sell the outstanding shares of AMPS subject to such Submitted
      Bid or Submitted Sell Order;

            (b) each Existing Holder that placed a Submitted Bid specifying a
      rate per annum lower than the Winning Bid Rate will continue to hold the
      outstanding shares of AMPS subject to such Submitted Bid;

            (c) each Potential Holder that placed a Submitted Bid specifying a
      rate per annum lower than the Winning Bid Rate will purchase the number
      of shares of AMPS subject to such Submitted Bid;

            (d) each Existing Holder that placed a Submitted Bid specifying a
      rate per annum equal to the Winning Bid Rate will continue to hold the
      outstanding shares of AMPS subject to such Submitted Bids, unless the
      number of outstanding shares of AMPS subject to all such Submitted Bids
      of Existing Holders is greater than the excess of the Available AMPS
      over the number of shares of AMPS accounted for in clauses (b) and (c)
      above, in which event each Existing Holder with such a Submitted Bid
      will sell a number of outstanding shares of AMPS determined on a pro
      rata basis based on the number of outstanding shares of AMPS subject to
      all such Submitted Bids of such Existing Holders; and

            (e) each Potential Holder that placed a Submitted Bid specifying a
      rate per annum equal to the Winning Bid Rate will purchase any Available
      AMPS not accounted for in clause (b), (c) or (d) above on a pro rata
      basis based on the shares of AMPS subject to all such Submitted Bids of
      Potential Holders.

      If Sufficient Clearing Bids have not been made (other than because all
outstanding shares of AMPS are the subject of Submitted Hold Orders):

            (a) each Existing Holder that placed a Submitted Bid specifying a
      rate per annum equal to or lower than the Maximum Applicable Rate will
      continue to hold the outstanding shares of AMPS subject to such
      Submitted Bid;

            (b) each Potential Holder that placed a Submitted Bid specifying a
      rate per annum equal to or lower than the Maximum Applicable Rate will
      purchase the number of shares of AMPS subject to such Submitted Bid; and

            (c) each Existing Holder that placed a Submitted Bid specifying a
      rate per annum higher than the Maximum Applicable Rate or a Submitted
      Sell Order will sell a number of outstanding shares of AMPS determined
      on a pro rata basis based on the outstanding shares of AMPS subject to
      all such Submitted Bids and Submitted Sell Orders.

      If as a result of the Auction Procedures described above any Existing
Holder would be entitled or required to sell, or any Potential Holder would be
entitled or required to purchase, a fraction of a share of AMPS, the Auction
Agent, in such manner as, in its sole discretion, it shall determine, will
round up or down the number of shares of AMPS being sold or purchased on such
Auction Date so that each share sold or purchased by each Existing Holder



                                      41
<PAGE>

or Potential Holder will be a whole share of AMPS. If any Potential Holder
would be entitled or required to purchase less than a whole share of AMPS, the
Auction Agent, in such manner as, in its sole discretion, it shall determine,
will allocate shares of AMPS for purchase among Potential Holders so that only
whole shares of AMPS are purchased by any such Potential Holder, even if such
allocation results in one or more of such Potential Holders not purchasing any
shares of AMPS.

      Notification of Results; Settlement. The Auction Agent will advise each
Broker-Dealer who submitted a Bid or Sell Order in an Auction whether such Bid
or Sell Order was accepted or rejected in whole or in part and of the
Applicable Rate for the next Dividend Period for the related shares of AMPS by
telephone at approximately 3:00 p.m., Eastern time, on the Auction Date for
such Auction. Each such Broker-Dealer that submitted an Order for the account
of a customer then will advise such customer whether such Bid or Sell Order
was accepted or rejected, will confirm purchases and sales with each customer
purchasing or selling shares of AMPS as a result of the Auction and will
advise each customer purchasing or selling shares of AMPS to give instructions
to its Agent Member of the Securities Depository to pay the purchase price
against delivery of such shares or to deliver such shares against payment
therefor as appropriate. If a customer selling shares of AMPS as a result of
an Auction shall fail to instruct its Agent Member to deliver such shares, the
Broker-Dealer that submitted such customer's Bid or Sell Order will instruct
such Agent Member to deliver such shares against payment therefor. Each
Broker-Dealer that submitted a Hold Order in an Auction on behalf of a
customer also will advise such customer of the Applicable Rate for the next
Dividend Period for the AMPS. The Auction Agent will record each transfer of
shares of AMPS on the record book of Existing Holders to be maintained by the
Auction Agent. In accordance with the Securities Depository's normal
procedures, on the day after each Auction Date, the transactions described
above will be executed through the Securities Depository, and the accounts of
the respective Agent Members at the Securities Depository will be debited and
credited as necessary to effect the purchases and sales of shares of AMPS as
determined in such Auction. Purchasers will make payment through their Agent
Members in same-day funds to the Securities Depository against delivery
through their Agent Members; the Securities Depository will make payment in
accordance with its normal procedures, which now provide for payment in
same-day funds. If the procedures of the Securities Depository applicable to
AMPS shall be changed to provide for payment in next-day funds, then
purchasers may be required to make payment in next day funds. If any Existing
Holder selling shares of AMPS in an Auction fails to deliver such shares, the
Broker-Dealer of any person that was to have purchased shares of AMPS in such
Auction may deliver to such person a number of whole shares of AMPS that is
less than the number of shares that otherwise was to be purchased by such
person. In such event, the number of shares of AMPS to be so delivered will be
determined by such Broker-Dealer. Delivery of such lesser number of shares
will constitute good delivery. Each Broker-Dealer Agreement also will provide
that neither the Fund nor the Auction Agent will have responsibility or
liability with respect to the failure of a Potential Beneficial Owner,
Beneficial Owner or their respective Agent Members to deliver shares of AMPS
or to pay for shares of AMPS purchased or sold pursuant to an Auction or
otherwise.

Broker-Dealers

      General. The Broker-Dealer Agreements provide that a Broker-Dealer may
submit Orders in Auctions for its own account, unless the Fund notifies all
Broker-Dealers that they no longer may do so; provided that Broker-Dealers may
continue to submit Hold Orders and Sell Orders. If a Broker-Dealer submits an
Order for its own account in any Auction of the AMPS, it may have knowledge of
Orders placed through it in that Auction and therefore have an advantage over
other Bidders, but such Broker-Dealer would not have knowledge of Orders
submitted by other Broker-Dealers in that Auction. As a result of bidding by a
Broker-Dealer in an Auction, the Applicable Rate may be higher or lower than
the rate that would have prevailed had the Broker-Dealer not Bid.

      A Broker-Dealer may also Bid in an Auction in order to prevent what
would otherwise be (i) a failed Auction, (ii) an "all-hold" Auction, or (iii)
an Applicable Rate that the Broker-Dealer believes, in its sole discretion,
does not reflect the market for the AMPS at the time of the Auction. A
Broker-Dealer may, but is not obligated to, advise Beneficial Owners of AMPS
that the Applicable Rate that would apply in an "all-hold" Auction (i.e., all
of the outstanding AMPS are subject to Submitted Hold Orders) may be lower
than would apply if Beneficial Owners submit Bids and such advice, if given,
may facilitate the submission of Bids by Beneficial Owners that would avoid
the occurrence of an "all-hold" Auction.



                                      42
<PAGE>

      Commission Inquiries. Merrill Lynch has advised the Fund that it and
various other broker-dealers and other firms that participate in the auction
rate securities market received letters from the staff of the Securities and
Exchange Commission last spring. The letters requested that each of these
firms voluntarily conduct an investigation regarding its respective practices
and procedures in that market. Pursuant to this request, Merrill Lynch
conducted its own voluntary review and reported its findings to the Commission
staff. At the Commission staff's request, Merrill Lynch, together with certain
other broker-dealers and other firms that participate in the auction rate
securities market, is engaging in discussions with the Commission staff
concerning its inquiry. Neither Merrill Lynch nor the Fund can predict the
ultimate outcome of the inquiry or how that outcome will affect the market for
the AMPS or the auctions.

      Fees. The Auction Agent after each Auction will pay a service charge
from funds provided by the Fund to each Broker-Dealer on the basis of the
purchase price of shares of AMPS placed by such Broker-Dealer at such Auction.
The service charge (i) for any 7-Day Dividend Period shall be payable at the
annual rate of 0.25% of the purchase price of the shares of AMPS placed by
such Broker-Dealer in any such Auction and (ii) for any Special Dividend
Period shall be determined by mutual consent of the Fund and any such
Broker-Dealer or Broker-Dealers and shall be based upon a selling concession
that would be applicable to an underwriting of fixed or variable rate
preferred shares with a similar final maturity or variable rate dividend
period, respectively, at the commencement of the Dividend Period with respect
to such Auction. For the purposes of the preceding sentence, shares of AMPS
will be placed by a Broker-Dealer if such shares were (i) the subject of Hold
Orders deemed to have been made by Beneficial Owners that were acquired by
such Beneficial Owners through such Broker-Dealer or (ii) the subject of the
following Orders submitted by such Broker-Dealer: (A) a Submitted Bid of a
Beneficial Owner that resulted in such Beneficial Owner continuing to hold
such shares as a result of the Auction, (B) a Submitted Bid of a Potential
Beneficial Owner that resulted in such Potential Beneficial Owner purchasing
such shares as a result of the Auction or (C) a Submitted Hold Order. A
Broker-Dealer may share a portion of any such fees with non-participating
broker-dealers that submit Orders to the Broker-Dealer for an Auction that are
placed by that Broker-Dealer in such Auction.

      Secondary Trading Market. Broker-Dealers have no obligation to maintain
a secondary trading market in the AMPS outside of Auctions and there can be no
assurance that a secondary market for the AMPS will develop or, if it does
develop, that it will provide holders with a liquid trading market (i.e.,
trading will depend on the presence of willing buyers and sellers and the
trading price is subject to variables to be determined at the time of the
trade by the Broker-Dealers). The AMPS will not be registered on any stock
exchange or on any automated quotation system. An increase in the level of
interest rates, particularly during any Long Term Dividend Period, likely will
have an adverse effect on the secondary market price of the AMPS, and a
selling stockholder may sell AMPS between Auctions at a price per share of
less than $25,000.

                           RATING AGENCY GUIDELINES

      Certain of the capitalized terms used herein not otherwise defined in
this prospectus have the meaning provided in the Glossary at the back of this
prospectus.

      The Fund currently intends that, so long as shares of AMPS are
outstanding and the AMPS are rated by Moody's and S&P, the composition of its
portfolio will reflect guidelines established by Moody's and S&P in connection
with the Fund's receipt of a rating for such shares on or prior to their Date
of Original Issue of at least Aaa from Moody's and AAA from S&P. Moody's and
S&P, which are NRSROs, issue ratings for various securities reflecting the
perceived creditworthiness of such securities. The Board of Directors of the
Fund, however, may determine that it is not in the best interest of the Fund
to continue to comply with the guidelines of Moody's or S&P (described below).
If the Fund voluntarily terminates compliance with Moody's or S&P guidelines,
the Fund will no longer be required to maintain a Moody's Discounted Value or
a S&P Discounted Value, as applicable, at least equal to the AMPS Basic
Maintenance Amount. If the Fund voluntarily terminates compliance with Moody's
or S&P guidelines, or both, at the time of termination, it must continue to be
rated by at least one NRSRO.

      The guidelines described below have been developed by Moody's and S&P in
connection with issuances of asset-backed and similar securities, including
debt obligations and variable rate preferred stock, generally on a
case-by-case basis through discussions with the issuers of these securities.
The guidelines are designed to ensure that assets underlying outstanding debt
or preferred stock will be varied sufficiently and will be of sufficient
quality and



                                      43
<PAGE>

amount to justify investment-grade ratings. The guidelines do not have the
force of law but have been adopted by the Fund in order to satisfy current
requirements necessary for Moody's and S&P to issue the above-described
ratings for shares of AMPS, which ratings generally are relied upon by
institutional investors in purchasing such securities. The guidelines provide
a set of tests for portfolio composition and asset coverage that supplement
(and in some cases are more restrictive than) the applicable requirements
under the 1940 Act. See "Description of AMPS--Asset Maintenance" herein and in
the statement of additional information.

      The Fund intends to maintain a Discounted Value for its portfolio at
least equal to the AMPS Basic Maintenance Amount. Moody's and S&P each has
established separate guidelines for determining Discounted Value. To the
extent any particular portfolio holding does not satisfy the applicable rating
agency's guidelines, all or a portion of such holding's value will not be
included in the calculation of Discounted Value (as defined by such rating
agency). The Moody's and S&P guidelines do not impose any limitations on the
percentage of Fund assets that may be invested in holdings not eligible for
inclusion in the calculation of the Discounted Value of the Fund's portfolio.

      Upon any failure to maintain the required Discounted Value, the Fund
will seek to alter the composition of its portfolio to reattain a Discounted
Value at least equal to the AMPS Basic Maintenance Amount on or prior to the
AMPS Basic Maintenance Cure Date, thereby incurring additional transaction
costs and possible losses and/or gains on dispositions of portfolio
securities. To the extent any such failure is not cured in a timely manner,
shares of AMPS will be subject to redemption. See "Description of AMPS--Asset
Maintenance" and "Description of AMPS--Redemption" herein and in the statement
of additional information.

      The Fund may, but is not required to, adopt any modifications to these
guidelines that hereafter may be established by Moody's or S&P. Failure to
adopt any such modifications, however, may result in a change in the ratings
described above or a withdrawal of ratings altogether. In addition, any rating
agency providing a rating for the shares of AMPS, at any time, may change or
withdraw any such rating. As set forth in the Articles Supplementary, the
Board of Directors, without stockholder approval, may modify certain
definitions or restrictions that have been adopted by the Fund pursuant to the
rating agency guidelines, provided the Board of Directors has obtained written
confirmation from Moody's and S&P that any such change would not impair the
ratings then assigned by Moody's and S&P to the AMPS.

      As described by Moody's and S&P, a preferred stock rating is an
assessment of the capacity and willingness of an issuer to pay preferred stock
obligations. The ratings on the AMPS are not recommendations to purchase, hold
or sell shares of AMPS, inasmuch as the ratings do not comment as to market
price or suitability for a particular investor, nor do the rating agency
guidelines described above address the likelihood that a holder of shares of
AMPS will be able to sell such shares in an Auction. The ratings are based on
current information furnished to Moody's and S&P by the Fund and the
Investment Adviser and information obtained from other sources. The ratings
may be changed, suspended or withdrawn as a result of changes in, or the
unavailability of, such information. The common stock has not been rated by a

               INVESTMENT ADVISORY AND MANAGEMENT ARRANGEMENTS

      The Investment Adviser, which is owned and controlled by Merrill Lynch &
Co. Inc. ("ML & Co."), a financial services holding company and the parent of
Merrill Lynch, provides the Fund with investment advisory and administrative
services. The Investment Adviser acts as the investment adviser to more than
50 registered investment companies and offers investment advisory services to
individuals and institutional accounts. As of June 30, 2005, the Investment
Adviser and its affiliates, including Merrill Lynch Investment Managers, L.P.
("MLIM"), had a total of approximately $474 billion in investment company and
other portfolio assets under management, including approximately $221 billion
in fixed income assets. This amount includes assets managed by certain
affiliates of the Investment Adviser. The Investment Adviser is a limited
partnership, the partners of which are ML & Co. and Princeton Services. The
principal business address of the Investment Adviser is 800 Scudders Mill
Road, Plainsboro, New Jersey 08536.



                                      44

      The Investment Advisory Agreement provides that, subject to the
oversight of the Fund's Board of Directors, the Investment Adviser is
responsible for the actual management of the Fund's portfolio. The
responsibility for making decisions to buy, sell or hold a particular security
rests with the Investment Adviser, subject to oversight by the Board of
Directors.

      The portfolio manager primarily responsible for the Fund's day-to-day
management is Robert A. DiMella. Mr. DiMella has been a portfolio manager with
MLIM since 1997, was a Vice President of MLIM from 1997 to 2001, was a
Director (Tax-Exempt Fund Management) of MLIM from 2002 to 2004, has been a
Managing Director of MLIM since 2004 and has 15 years of experience investing
in Municipal Bonds as a portfolio manager on behalf of registered investment
companies. He has been the portfolio manager and a Vice President of the Fund
since [ ]. The Fund's portfolio manager will consider analyses from various
sources, make the necessary investment decisions, and place orders for
transactions accordingly. The statement of additional information provides
additional information about the Fund's portfolio manager's compensation,
other accounts managed by the portfolio manager, and the portfolio manager's
ownership of securities of the Fund.

      For its services, the Fund pays the Investment Adviser a monthly fee at
the annual rate of 0.55% of the Fund's average weekly net assets ("average
weekly net assets" means the average weekly value of the total assets of the
Fund, including the proceeds from the issuance of preferred stock, minus the
sum of (i) accrued liabilities of the Fund, (ii) any accrued and unpaid
interest on outstanding borrowings and (iii) accumulated dividends on shares
of preferred stock). For purposes of this calculation, average weekly net
assets is determined at the end of each month on the basis of the average net
assets of the Fund for each week during the month. The assets for each weekly
period are determined by averaging the net assets at the last business day of
a week with the net assets at the last business day of the prior week. The
liquidation preference of any outstanding preferred stock (other than
accumulated dividends) is not considered a liability in determining the Fund's
average daily net assets.

      The Investment Advisory Agreement obligates the Investment Adviser to
provide investment advisory services and to pay all compensation of and
furnish office space for officers and employees of the Fund connected with
investment and economic research, trading and investment management of the
Fund, as well as the compensation of all Directors of the Fund who are
affiliated persons of the Investment Adviser or any of its affiliates. The
Fund pays all other expenses incurred in the operation of the Fund, including,
among other things, expenses for legal and auditing services, taxes, costs of
preparing, printing and mailing proxies, listing fees, stock certificates and
stockholder reports, charges of the custodian and the transfer agent, dividend
disbursing agent and registrar, Securities and Exchange Commission fees, fees
and expenses of non-interested Directors, accounting and pricing costs,
insurance, interest, brokerage costs, litigation and other extraordinary or
non-recurring expenses, mailing and other expenses properly payable by the
Fund. Certain accounting services are provided to the Fund by State Street
Bank and Trust Company ("State Street") pursuant to an agreement between State
Street and the Fund. The Fund will pay the costs of these services. In
addition, the Fund will reimburse the Investment Adviser for certain
additional accounting services.

      For a discussion of the basis for the Board of Directors' most recent
approval of the Fund's Investment Advisory Agreement, see the Fund's annual
shareholder report for the period ended April 30, 2005.

                                     TAXES

      To the extent derived from Municipal Bond interest income, dividends on
the AMPS will be excludable from gross income for Federal income tax purposes
in the hands of holders of such AMPS, subject to the possible application of
the Federal alternative minimum tax and any state or local income taxes.
Interest income from other investments may produce taxable dividends. The Fund
is required to allocate net capital gain and other taxable income, if any,
proportionately among the common stock and the AMPS and Other AMPS in
accordance with the current position of the IRS described under the heading
"Taxes" in the statement of additional information. The Fund may notify the
Auction Agent of the amount of any net capital gain or other anticipated
taxable income to be included in any dividend on the AMPS prior to the Auction
establishing the Applicable Dividend Rate for such dividend. The Auction Agent
will in turn notify holders of the AMPS and prospective purchasers. The Fund
also may include such income in a dividend on shares of AMPS without giving
advance notice thereof if it increases the dividend by an additional amount
calculated as if such income were a Retroactive Taxable Allocation and the
additional amount were an Additional Dividend. See "The Auction-- Auction
Procedures--Auction Date; Advance



                                      45
<PAGE>

Notice of Allocation of Taxable Income; Inclusion of Taxable Income in
Dividends." The amount of taxable income allocable to the AMPS will depend
upon the amount of such income realized by the Fund and cannot be determined
with certainty prior to the end of the Fund's fiscal year, but it is not
generally expected to be significant.

      If the Fund makes a Retroactive Taxable Allocation, it will pay
Additional Dividends to holders of AMPS who are subject to the Retroactive
Taxable Allocation. See "Description of AMPS--Dividends--Additional
Dividends." The Federal income tax consequences of Additional Dividends under
existing law are uncertain. The Fund intends to treat a holder as receiving a
dividend distribution in the amount of any Additional Dividend only as and
when such Additional Dividend is paid. An Additional Dividend generally will
be designated by the Fund as an exempt-interest dividend except as otherwise
required by applicable law. However, the IRS may assert that all or part of an
Additional Dividend is a taxable dividend either in the taxable year for which
the Retroactive Taxable Allocation is made or in the taxable year in which the
Additional Dividend is paid.

      Generally within 60 days after the end of the Fund's taxable year, the
Fund will tell you the amount of exempt-interest dividends and capital gain
dividends you received during that year. Capital gain dividends are taxable as
long-term capital gains to you regardless of how long you have held your
shares.

      The Fund will only purchase a Municipal Bond or Non-Municipal Tax Exempt
Security if it is accompanied by an opinion of counsel to the issuer, which is
delivered on the date of issuance of the security, that the interest paid on
such security is excludable from gross income for Federal income tax purposes
(i.e., "tax exempt"). To the extent that the dividends distributed by the Fund
are from interest income that is excludable from gross income for Federal
income tax purposes, they are exempt from Federal income tax. There is a
possibility that events occurring after the date of issuance of a security, or
after a Fund's acquisition of a security, may result in a determination that
the interest on that security is, in fact, includable in gross income for
Federal income tax purposes retroactively to its date of issue. Such a
determination may cause a portion of prior distributions received by
stockholders, including holders of AMPS, to be taxable to those stockholders
in the year of receipt. The Fund will not pay an Additional Dividend to a
holder of AMPS under these circumstances.

      Because the Fund may from time to time invest a substantial portion of
its portfolio in Municipal Bonds bearing income that could increase an AMPS
holder's tax liability under the Federal alternative minimum tax, the Fund
would not ordinarily be a suitable investment for investors who are subject to
the alternative minimum tax.

      If at any time when AMPS are outstanding the Fund does not meet the
asset coverage requirements of the 1940 Act, the Fund will be required to
suspend distributions to holders of common stock until the asset coverage is
restored. See "Description of AMPS--Dividends--Restrictions on Dividends and
Other Payments" herein and in the statement of additional information. This
may prevent the Fund from meeting certain distribution requirements for
qualification as a RIC. Upon any failure to meet the asset coverage
requirements of the 1940 Act, the Fund, in its sole discretion, may, and under
certain circumstances will be required to, redeem AMPS in order to maintain or
restore the requisite asset coverage and avoid the adverse consequences to the
Fund and its stockholders of failing to qualify as a RIC. See "Description of
AMPS--Redemption" herein and in the statement of additional information. There
can be no assurance, however, that any such action would achieve such
objectives.

      By law, your dividends and redemption proceeds will be subject to a
withholding tax if you have not provided a tax identification number or social
security number or if the number you have provided is incorrect.

      This section summarizes some of the consequences of an investment in the
Fund under current Federal income tax laws. It is not a substitute for
personal tax advice. Stockholders are urged to consult their tax advisers
regarding the applicability of any state or local taxes and with specific
questions regarding Federal taxes.

                         DESCRIPTION OF CAPITAL STOCK

      The Fund is authorized to issue 200,000,000 shares of capital stock, par
value $.10 per share, all of which shares initially were classified as common
stock. The Board of Directors is authorized, however, to classify and
reclassify any unissued shares of capital stock into one or more additional or
other classes or series as may be established from time to time by setting or
changing in any one or more respects the designations, preferences,



                                      46
<PAGE>

conversion or other rights, voting powers, restrictions, limitations as to
dividends, qualifications or terms or conditions of redemption of such shares
of stock and pursuant to such classification or reclassification to increase
or decrease the number of authorized shares of any existing class or series.
In this regard, the Board of Directors previously reclassified 4,400 shares of
unissued common stock as Other AMPS and reclassified 600 shares of unissued
common stock as AMPS, which are being offered hereby. See "Description of
AMPS" herein and in the statement of additional information.

      The following table shows the amount of (i) capital stock authorized,
(ii) capital stock held by the Fund for its own account and (iii) capital
stock outstanding for each class of authorized securities of the Fund as of
April 30, 2005.

      The Fund will send unaudited reports at least semi-annually and audited
annual financial statements to all of its stockholders.

Common Stock

      Holders of common stock are entitled to share equally in dividends
declared by the Board of Directors payable to holders of common stock and in
the net assets of the Fund available for distribution to holders of common
stock after payment of the preferential amounts payable to holders of any
outstanding preferred stock. Neither holders of common stock nor holders of
preferred stock have pre-emptive or conversion rights and shares of common
stock are not redeemable. The outstanding shares of common stock are fully
paid and non-assessable.

      Holders of common stock are entitled to one vote for each share held and
will vote with the holders of any outstanding shares of AMPS or other
preferred stock, including the Other AMPS, on each matter submitted to a vote
of holders of common stock, except as described under "Description of
AMPS--Voting Rights" herein and in the statement of additional information.

      Stockholders are entitled to one vote for each share held. The shares of
common stock, AMPS, Other AMPS and any other preferred stock do not have
cumulative voting rights, which means that the holders of more than 50% of the
shares of common stock, AMPS, Other AMPS and any other preferred stock voting
for the election of Directors can elect all of the Directors standing for
election by holders, and, in such event, the holders of the remaining shares
of common stock, AMPS, Other AMPS and any other preferred stock will not be
able to elect any of such Directors.

      So long as any shares of the Fund's preferred stock are outstanding,
including the AMPS and Other AMPS, holders of common stock will not be
entitled to receive any net income of or other distributions from the Fund
unless all accumulated dividends on preferred stock have been paid, and unless
asset coverage (as defined in the 1940 Act) with respect to preferred stock
would be at least 200% after giving effect to such distributions. See
"Description of AMPS--Dividends--Restrictions on Dividends and Other Payments"
herein and in the statement of additional information.

Preferred Stock

      The Fund has issued an aggregate of 4,400 shares of Other AMPS. Under
the Articles Supplementary for the AMPS, the Fund is authorized to issue an
aggregate of 600 additional shares of AMPS. The terms of the shares of Other
AMPS are substantially the same as the terms of the shares of AMPS. See
"Description of AMPS." Under the 1940 Act, the Fund is permitted to have
outstanding more than one series of preferred stock as long as no single



                                      47
<PAGE>

series has priority over another series as to the distribution of assets of
the Fund or the payment of dividends. Neither holders of common stock nor
holders of preferred stock have pre-emptive rights to purchase any shares of
AMPS, Other AMPS or any other preferred stock that might be issued. It is
anticipated that the net asset value per share of the AMPS will equal its
original purchase price per share plus accumulated dividends per share.

Certain Provisions of the Charter and By-laws

      The Fund's Charter includes provisions that could have the effect of
limiting the ability of other entities or persons to acquire control of the
Fund or to change the composition of its Board of Directors and could have the
effect of depriving common stockholders of an opportunity to sell their shares
at a premium over prevailing market prices by discouraging a third party from
seeking to obtain control of the Fund. A Director may be removed from office
with or without cause by vote of the holders of at least 66 2/3% of the shares
entitled to vote in an election to fill that directorship. A director elected
by all of the holders of capital stock may be removed only by action of such
holders, and a director elected by the holders of AMPS and any other preferred
stock may be removed only by action of the holders of AMPS and any other
preferred stock.

      In addition, the Charter requires the favorable vote of the holders of
at least 66 2/3% of the Fund's shares to approve, adopt or authorize the
following:

      o   a merger or consolidation or statutory share exchange of the Fund
          with any other corporation;

      o   a sale of all or substantially all of the Fund's assets (other than
          in the regular course of the Fund's investment activities); or

      o   a liquidation or dissolution of the Fund;

unless such action has been approved, adopted or authorized by the affirmative
vote of at least two-thirds of the total number of Directors fixed in
accordance with the By-laws, in which case the affirmative vote of a majority
of the Fund's shares of capital stock is required. The approval, adoption or
authorization of the foregoing also requires the favorable vote of a majority
of the Fund's outstanding shares (as defined in the 1940 Act) of preferred
stock, including the AMPS and Other AMPS, then entitled to be voted, voting as
a separate class.

      In addition, conversion of the Fund to an open-end investment company
would require an amendment to the Fund's Charter. The amendment would have to
be declared advisable by the Board of Directors prior to its submission to
stockholders. Such an amendment would require the favorable vote of the
holders of at least 66 2/3% of the Fund's outstanding shares of capital stock
(including the AMPS, the Other AMPS and any other preferred stock) entitled to
be voted on the matter, voting as a single class (or a majority of such shares
if the amendment was previously approved, adopted or authorized by at least
two-thirds of the total number of Directors fixed in accordance with the
By-laws), and the affirmative vote of a majority of outstanding shares (as
defined in the 1940 Act) of preferred stock of the Fund (including the AMPS
and the Other AMPS), voting as a separate class. Such a vote also would
satisfy a separate requirement in the 1940 Act that the change be approved by
the stockholders. Stockholders of an open-end investment company may require
the company to redeem their shares of common stock at any time (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 a redemption. If the Fund is converted to an open-end investment
company, it could be required to liquidate portfolio securities to meet
requests for redemption, and the common stock would no longer be listed on a
stock exchange. Conversion to an open-end investment company would also
require redemption of all outstanding shares of preferred stock (including the
AMPS and Other AMPS) and would require changes in certain of the Fund's
investment policies and restrictions, such as those relating to the issuance
of senior securities, the borrowing of money and the purchase of illiquid
securities.

     The Charter and By-laws provide that the Board of Directors has the
power, to the exclusion of stockholders, to make, alter or repeal any of the
By-laws (except for any By-law specified not to be amended or repealed by the
Board), subject to the requirements of the 1940 Act. Neither this provision of
the Charter, nor any of the foregoing provisions of the Charter requiring the
affirmative vote of 66 2/3% of shares of capital stock of the Fund can be
amended or repealed except by the vote of such required number of shares.



                                      48
<PAGE>

      The Board of Directors has determined that the 66?% voting requirements
described above, which are greater than the minimum requirements under
Maryland law or the 1940 Act, are in the best interests of stockholders
generally. Reference should be made to the Charter on file with the Securities
and Exchange Commission for the full text of these provisions.

officer's certificates and legal opinions. The Underwriter reserves the right
to withdraw, cancel or modify offers to the public and to reject orders in
whole or in part.

Commissions and Discounts

      The Underwriter has advised the Fund that it proposes initially to offer
the shares of AMPS to the public at the initial public offering price on the
cover page of this prospectus and to dealers at that price less a concession
not in excess of $137.50 per share. There is a sales charge or underwriting
discount of $250 per share, which is equal to 1% of the initial public
offering price per share. After the initial public offering, the public
offering price and concession may be changed. Investors must pay for any AMPS
purchased in the offering on or before [ ], 2005.

      The expenses of the offering, excluding underwriting discount, are
estimated at $135,000 and are payable by the Fund.

the opinion of bond counsel to the issuer, is excludable from gross income for
Federal income tax purposes (except that the interest may be includable in
taxable income for purposes of the Federal alternative minimum tax). Under
normal market conditions, the Fund expects to invest at least 75% of its total
assets in municipal obligations that are rated investment grade or, if
unrated, are considered by the Fund's investment adviser to be of comparable
quality. The Fund may invest up to 25% of its total assets in high yield
municipal obligations that are rated below investment grade (commonly known as
"junk bonds") or, if unrated, are considered by the Fund's investment adviser
to possess similar credit characteristics. The Fund invests primarily in long
term municipal obligations. The Fund may invest in certain tax exempt
securities classified as "private activity bonds," as discussed within, that
may subject certain investors in the Fund to an alternative minimum tax. There
can be no assurance that the Fund's investment objective will be realized.

                       INVESTMENT OBJECTIVE AND POLICIES

      The Fund's investment objective is to provide shareholders with current
income exempt from Federal income taxes. The Fund seeks to achieve its
investment objective by investing, as a fundamental policy, at least 80% of an
aggregate of the Fund's net assets (including proceeds from the issuance of
preferred stock) and the proceeds of any borrowings for investment purposes,
in a portfolio of municipal obligations issued by or on behalf of states,
territories and possessions of the United States and their political
subdivisions, agencies or instrumentalities, each of which pays interest that,
in the opinion of bond counsel to the issuer, is excludable from gross income
for Federal income tax purposes (except that the interest may be includable in
taxable income for purposes of the Federal alternative minimum tax)
("Municipal Bonds"). The Fund's investment objective and its policy of
investing at least 80% of an aggregate of the Fund's net assets (including
proceeds from the issuance of any preferred stock) and the proceeds of any
borrowings for investment purposes, in Municipal Bonds are fundamental
policies that may not be changed without the approval of a majority of the
outstanding voting securities of the Fund (as defined in the 1940 Act). There
can be no assurance that the Fund's investment objective will be realized.

      Reference is made to "Investment Objective and Policies" and "Other
Investment Policies" in the prospectus for information regarding other types
of securities that the Fund may invest in to achieve its objective.

                            INVESTMENT RESTRICTIONS

      The following are fundamental investment restrictions of the Fund and
may not be changed without the approval of the holders of a majority of the
Fund's outstanding shares of common stock and outstanding shares of AMPS,
Other AMPS and any other preferred stock, voting together as a single class,
and a majority of the outstanding shares of AMPS, Other AMPS and any other
preferred stock, voting as a separate class (which for this purpose and under
the 1940 Act means the lesser of (i) 67% of the shares of each class of
capital stock represented at a meeting at which more than 50% of the
outstanding shares of each class of capital stock are represented or (ii) more
than 50% of the outstanding shares of each class of capital stock). The Fund
may not:

            1. Make investments for the purpose of exercising control or
      management.

            2. Purchase or sell real estate, real estate limited partnerships,
      commodities or commodity contracts; provided that the Fund may invest in
      securities secured by real estate or interests therein or issued by
      companies that invest in real estate or interest therein, and the Fund
      may purchase and sell financial futures contracts and options thereon..

            3. Issue senior securities or borrow money except as permitted by
      Section 18 of the 1940 Act.

            4. Underwrite securities of other issuers except insofar as the
      Fund may be deemed an underwriter under the Securities Act of 1933, as
      amended, in selling portfolio securities.

            5. Make loans to other persons, except that the Fund may purchase
      Municipal Bonds and other debt securities in accordance with is
      investment objective, policies and limitations.

            6. Invest more than 25% of its total assets (taken at market value
      at the time of each investment) in securities of issuers in a single
      industry; provided that, for purposes of this restriction, states,
      municipalities and their political subdivisions are not considered to be
      part of any industry.

      For purposes of investment restriction (6) above, the exception for
states, municipalities and their political subdivisions applies only to tax
exempt securities issued by such entities.

      Additional investment restrictions adopted by the Fund, which may be
changed by the Board of Directors without shareholder approval, provide that
the Fund may not:



                                      3
<PAGE>

      a. Purchase securities of other investment companies, except to the
extent that such purchases are permitted by applicable law. Applicable law
currently generally prohibits the Fund from purchasing the securities of other
investment companies except if immediately thereafter not more than (i) 3% of
the total outstanding voting stock of such company is owned by the Fund, (ii)
5% of the Fund's total assets, taken at market value, would be invested in any
one such company, (iii) 10% of the Fund's total assets, taken at market value,
would be invested in such securities, and (iv) the Fund, together with other
investment companies having the same investment adviser and companies
controlled by such companies, owns not more than 10% of the total outstanding
stock of any one closed-end investment company.

      b. Mortgage, pledge, hypothecate or in any manner transfer, as security
for indebtedness, any securities owned or held by the Fund except as may be
necessary in connection with borrowings mentioned in investment restriction
(3) above or except as may be necessary in connection with transactions in
financial futures contracts and options thereon.

      c. Purchase any securities on margin, except that the Fund may obtain
such short-term credit as may be necessary for the clearance of purchases and
sales of portfolio securities (the deposit or payment by the Fund of initial
or variation margin in connection with financial futures contracts and options
thereon is not considered the purchase of a security on margin).

      d. Make short sales of securities or maintain a short position or invest
in put, call, straddle or spread options, except that the Fund may write,
purchase and sell options and futures on Municipal Bonds, U.S. Government
obligations and related indices or otherwise in connection with bona fide
hedging activities and may purchase and sell Call Rights to require mandatory
tender for the purchase of related Municipal Bonds.

      If a percentage restriction on investment policies or the investment or
use of assets set forth above is adhered to at the time a transaction is
effected, later changes in percentages resulting from changing values will not
be considered a violation.

      The Fund is classified as non-diversified within the meaning of the 1940
Act, which means that the Fund is not limited by the 1940 Act in the
proportion of its assets that it may invest in securities of a single issuer.
As a non-diversified fund, the Fund's investments are limited, however, in
order to allow the Fund to continue to qualify as a regulated investment
company under the Internal Revenue Code of 1986, as amended (the "Code"). See
"Taxes." To qualify, the Fund complies with certain requirements, including
limiting its investments so that at the close of each quarter of the taxable
year (i) not more than 25% of the market value of the Fund's total assets will
be invested in the securities of a single issuer or in qualified publicly
traded partnerships as defined in the Code and (ii) with respect to 50% of the
market value of its total assets, not more than 5% of the market value of its
total assets will be invested in the securities of a single issuer and the
Fund will not own more than 10% of the outstanding voting securities of a
single issuer. For purposes of this restriction, the Fund will regard each
state and each political subdivision, agency or instrumentality of such state
and each multi-state agency of which such state is a member and each public
authority which issues securities on behalf of a private entity as a separate
issuer, except that if the security is backed only by the assets and revenues
of a non-government entity then the entity with the ultimate responsibility
for the payment of interest and principal may be regarded as the sole issuer.
These tax-related limitations may be changed by the Board of Directors of the
Fund to the extent necessary to comply with changes in the Federal tax
requirements. A fund that elects to be classified as "diversified" under the
1940 Act must satisfy the foregoing 5% and 10% requirements with respect to
75% of its total assets.

      The Investment Adviser of the Fund and Merrill Lynch, Pierce, Fenner &
Smith Incorporated ("Merrill Lynch") are owned and controlled by Merrill Lynch
& Co., Inc. ("ML & Co."). Because of the affiliation of Merrill Lynch with the
Investment Adviser, the Fund is prohibited from engaging in certain
transactions involving Merrill Lynch except pursuant to an exemptive order or
otherwise in compliance with the provisions of the 1940 Act and the rules and
regulations thereunder. Included among such restricted transactions will be
purchases from or sales to Merrill Lynch of securities in transactions in
which it acts as principal. See "Portfolio Transactions" in this statement of
additional information.

                              DESCRIPTION OF AMPS

      Certain of the capitalized terms used herein not otherwise defined in
this statement of additional information have the meaning provided in the
Glossary at the back of the prospectus.

      The Series C AMPS will be shares of preferred stock that entitle their
holders to receive dividends when, as and if declared by the Board of
Directors, out of funds legally available therefor, at a rate per annum that
may vary for the successive Dividend Periods. After the Initial Dividend
Period, each Subsequent Dividend Period for the Series C AMPS generally will
be a 7-Day Dividend Period; provided however, that prior to any Auction, the
Fund may elect, subject to certain limitations described herein, upon giving
notice to holders thereof, a Special Dividend Period. The Applicable Rate for
a particular Dividend Period will be determined by an Auction conducted on the
Business Day before the start of such Dividend Period. Beneficial Owners and
Potential Beneficial Owners of shares of AMPS may participate in Auctions
therefor, although, except in the case of a Special Dividend Period of more
than 28 days, Beneficial Owners desiring to continue to hold all of their
shares of AMPS regardless of the Applicable Rate resulting from Auctions need
not participate. For an explanation of Auctions and the method of determining
the Applicable Rate, see Appendix C--"Auction Procedures."

      Except as otherwise required by law or unless there is no Securities
Depository, all outstanding shares of the AMPS will be represented by one or
more certificates registered in the name of the nominee of the Securities
Depository (initially expected to be Cede), and no person acquiring shares of
AMPS will be entitled to receive a certificate representing such shares. See
Appendix C--"Auction Procedures." As a result, the nominee of the Securities
Depository is expected to be the sole holder of record of the shares of AMPS.
Accordingly, each purchaser of AMPS must rely on (i) the procedures of the
Securities Depository and, if such purchaser is not a member of the Securities
Depository, such purchaser's Agent Member, to receive dividends, distributions
and notices and to exercise voting rights (if and when applicable) and (ii)
the records of the Securities Depository and, if such purchaser is not a
member of the Securities Depository, such purchaser's Agent Member, to
evidence its beneficial ownership of shares of AMPS.

      When issued and sold, the shares of AMPS will have a liquidation
preference of $25,000 per share plus an amount equal to accumulated but unpaid
dividends (whether or not earned or declared) and will be fully paid and
non-assessable. See "Description of AMPS--Liquidation Rights" in the
prospectus. The shares of AMPS will not be convertible into shares of common
stock or other capital stock of the Fund, and the holders thereof will have no
preemptive rights. The AMPS will not be subject to any sinking fund but will
be subject to redemption at the option of the Fund at the Optional Redemption
Price on any Dividend Payment Date (except during the Initial Dividend Period
and during a Non-Call Period) and, under certain circumstances, will be
subject to mandatory redemption by the Fund at the Mandatory Redemption Price
stated in the prospectus. See "Description of AMPS--Redemption" in the
prospectus.

      The Fund also has outstanding two series of shares of Other AMPS with
terms that are substantially the same as the terms of the shares of AMPS
described herein and in the prospectus. Cede, the nominee of the Securities
Depository, 55 Water Street, New York, New York 10041-0099, is the sole holder
of record of the shares of Other AMPS. The Series C AMPS offered hereby rank
on a parity with the Other AMPS with respect to dividends and liquidation
preference.

      In addition to serving as the Auction Agent in connection with the
Auction Procedures described in the prospectus, The Bank of New York also
serves as the transfer agent, registrar, dividend disbursing agent and
redemption agent for the shares of AMPS. The Auction Agent, however, will
serve merely as the agent of the Fund, acting in accordance with the Fund's
instructions, and will not be responsible for any evaluation or verification
of any matters certified to it.

      Except in an Auction, the Fund will have the right (to the extent
permitted by applicable law) to purchase or otherwise acquire any shares of
AMPS so long as the Fund is current in the payment of dividends on AMPS and on
any other capital stock of the Fund ranking on a parity with the AMPS,
including the Other AMPS, with respect to the payment of dividends or upon
liquidation.



                                      5

      The following supplements the description of the terms of the shares of
AMPS set forth in the prospectus. This description does not purport to be
complete and is subject to and qualified in its entirety by reference to the
Fund's Charter and Articles Supplementary, including the provisions thereof
establishing the AMPS. The Fund's Charter and the form of Articles
Supplementary establishing the terms of the AMPS have been filed as exhibits
to the Registration Statement of which this statement of additional
information is a part.

Dividends

      General. The holders of shares of the Series C AMPS will be entitled to
receive, when, as and if declared by the Board of Directors of the Fund, out
of funds legally available therefor, cumulative cash dividends on their
shares, at the Applicable Rate. Dividends on the shares of AMPS so declared
and payable shall be paid (i) in preference to and in priority over any
dividends so declared and payable on the common stock, and (ii) to the extent
permitted under the Code and to the extent available, out of net tax exempt
income earned on the Fund's investments. Generally, dividends on shares of
AMPS, to the extent that they are derived from interest paid on Municipal
Bonds, will be exempt from Federal income taxes, subject to possible
application of the alternative minimum tax. See "Taxes."

      Notification of Dividend Period. In determining whether the Fund should
issue a Notice of Special Dividend for AMPS, the Broker-Dealers will consider
(i) existing short term and long term market rates and indices of such short
term and long term rates, (ii) existing market supply and demand for short
term and long term securities, (iii) existing yield curves for short term and
long term securities comparable to the AMPS, (iv) industry and financial
conditions that may affect the AMPS, (v) the investment objective of the Fund,
and (vi) the Dividend Periods and dividend rates at which current and
potential beneficial holders of the AMPS would remain or become beneficial
holders. If the Broker-Dealers shall not give the Fund a Response by such
second Business Day or if the Response states that given the factors set forth
above it is not advisable that the Fund give a Notice of Special Dividend
Period for the AMPS, the Fund may not give a Notice of Special Dividend Period
in respect of such Request for Special Dividend Period. In the event the
Response indicates that it is advisable that the Fund give a Notice of Special
Dividend Period for the AMPS, the Fund, by no later than the second Business
Day prior to such Auction Date, may give a notice (a "Notice of Special
Dividend Period") to the Auction Agent, the Securities Depository and each
Broker-Dealer, which notice will specify (i) the duration of the Special
Dividend Period, (ii) the Optional Redemption Price as specified in the
related Response, and (iii) the Specific Redemption Provisions, if any, as
specified in the related Response. The Fund also shall provide a copy of such
Notice of Special Dividend Period to Moody's and S&P. The Fund shall not give
a Notice of Special Dividend Period, and, if such Notice of Special Dividend
Period shall have been given already, shall give telephonic and written notice
of its revocation (a "Notice of Revocation") to the Auction Agent, each
Broker-Dealer, and the Securities Depository on or prior to the Business Day
prior to the relevant Auction Date if (x) either the 1940 Act AMPS Asset
Coverage is not satisfied or the Fund shall fail to maintain S&P Eligible
Assets and Moody's Eligible Assets each with an aggregate Discounted Value at
least equal to the AMPS Basic Maintenance Amount, in each case on the
Valuation Date immediately preceding the Business Day prior to the relevant
Auction Date on an actual basis and on a pro forma basis giving effect to the
proposed Special Dividend Period (using as a pro forma dividend rate with
respect to such Special Dividend Period the dividend rate which the
Broker-Dealers shall advise the Fund is an approximately equal rate for
securities similar to the AMPS with an equal dividend period), (y) sufficient
funds for the payment of dividends payable on the immediately succeeding
Dividend Payment Date have not been segregated in an account at the Fund's
custodian bank or on the books of the Fund by the close of business on the
third Business Day preceding the related Auction Date or (z) the
Broker-Dealers jointly advise the Fund that, after consideration of the
factors listed above, they have concluded that it is advisable to give a
Notice of Revocation. The Fund also shall provide a copy of such Notice of
Revocation to Moody's and S&P. If the Fund is prohibited from giving a Notice
of Special Dividend Period as a result of the factors enumerated in clause
(x), (y) or (z) above or if the Fund gives a Notice of Revocation with respect
to a Notice of Special Dividend Period, the next succeeding Dividend Period
will be a 7-Day Dividend Period. In addition, in the event Sufficient Clearing
Bids are not made in any Auction or an Auction is not held for any reason, the
next succeeding Dividend Period will be a 7-Day Dividend Period, and the Fund
may not again give a Notice of Special Dividend Period (and any such attempted
notice shall be null and void) until Sufficient Clearing Bids have been made
in an Auction with respect to a 7-Day Dividend Period.

      Non-Payment Period; Late Charge. A Non-Payment Period will commence if
the Fund fails to (i) declare, prior to the close of business on the second
Business Day preceding any Dividend Payment Date, for payment on or



                                      6
<PAGE>

(to the extent permitted as described below) within three Business Days after
such Dividend Payment Date to the persons who held such shares as of 12:00
noon, Eastern time, on the Business Day preceding such Dividend Payment Date,
the full amount of any dividend on shares of AMPS payable on such Dividend
Payment Date or (ii) deposit, irrevocably in trust, in same-day funds, with
the Auction Agent by 12:00 noon, Eastern time, (A) on such Dividend Payment
Date the full amount of any cash dividend on such shares (if declared) payable
on such Dividend Payment Date or (B) on any redemption date for shares of AMPS
called for redemption, the Mandatory Redemption Price per share of such AMPS
or, in the case of an optional redemption, the Optional Redemption Price per
share. Such Non-Payment Period will consist of the period commencing on and
including the aforementioned Dividend Payment Date or redemption date, as the
case may be, and ending on and including the Business Day on which, by 12:00
noon, Eastern time, all unpaid cash dividends and unpaid redemption prices
shall have been so deposited or otherwise shall have been made available to
the applicable holders in same-day funds, provided that a Non-Payment Period
for AMPS will not end unless the Fund shall have given at least five days' but
no more than 30 days' written notice of such deposit or availability to the
Auction Agent, the Securities Depository and all holders of shares of AMPS.
Notwithstanding the foregoing, the failure by the Fund to deposit funds as
provided for by clause (ii) (A) or (ii) (B) above within three Business Days
after any Dividend Payment Date or redemption date, as the case may be, in
each case to the extent contemplated below, shall not constitute a
"Non-Payment Period."

      The Applicable Rate for each Dividend Period for shares of AMPS,
commencing during a Non-Payment Period, will be equal to the Non-Payment
Period Rate; and each Dividend Period commencing after the first day of, and
during, a Non-Payment Period shall be a 7-Day Dividend Period. Any dividend on
shares of AMPS due on any Dividend Payment Date for such shares (if, prior to
the close of business on the second Business Day preceding such Dividend
Payment Date, the Fund has declared such dividend payable on such Dividend
Payment Date to the persons who held such shares as of 12:00 noon, Eastern
time, on the Business Day preceding such Dividend Payment Date) or redemption
price with respect to such shares not paid to such persons when due may be
paid to such persons in the same form of funds by 12:00 noon, Eastern time, on
any of the first three Business Days after such Dividend Payment Date or due
date, as the case may be, provided that such amount is accompanied by a late
charge calculated for such period of non-payment at the Non-Payment Period
Rate applied to the amount of such non-payment based on the actual number of
days comprising such period divided by 365. In the case of a willful failure
of the Fund to pay a dividend on a Dividend Payment Date or to redeem any
shares of AMPS on the date set for such redemption, the preceding sentence
shall not apply and the Applicable Rate for the Dividend Period commencing
during the Non-Payment Period resulting from such failure shall be the
Non-Payment Period Rate. For the purposes of the foregoing, payment to a
person in same-day funds on any Business Day at any time will be considered
equivalent to payment to that person in New York Clearing House (next-day)
funds at the same time on the preceding Business Day, and any payment made
after 12:00 noon, Eastern time, on any Business Day shall be considered to
have been made instead in the same form of funds and to the same person before
12:00 noon, Eastern time, on the next Business Day.

      The Non-Payment Period Rate initially will be 200% of the applicable
Reference Rate (or 300% of such rate if the Fund has provided notification to
the Auction Agent prior to the Auction establishing the Applicable Rate for
any dividend that net capital gain or other taxable income will be included in
such dividend on shares of AMPS), provided that the Board of Directors of the
Fund shall have the authority to adjust, modify, alter or change from time to
time by resolution or otherwise the initial Non-Payment Period Rate if the
Board of Directors of the Fund determines and Moody's and S&P (and any
Substitute Rating Agency or Substitute Rating Agencies, as the case may be, in
lieu of Moody's or S&P, or both, in the event either or both of such parties
shall not rate the AMPS) advise the Fund in writing that such adjustment,
modification, alteration or change will not adversely affect their then
current ratings on the AMPS.

      Restrictions on Dividends and Other Payments. For so long as any shares
of AMPS are outstanding, the Fund will not declare, pay or set apart for
payment any dividend or other distribution (other than a dividend or
distribution paid in shares of, or options, warrants or rights to subscribe
for or purchase, common stock or other stock, if any, ranking junior to shares
of AMPS as to dividends or upon liquidation) in respect of common stock or any
other stock of the Fund ranking junior to or on a parity with shares of AMPS
as to dividends or upon liquidation, or call for redemption, redeem, purchase
or otherwise acquire for consideration any shares of common stock or any other
such junior stock (except by conversion into or exchange for stock of the Fund
ranking junior to AMPS as to dividends and upon liquidation) or any such
parity stock (except by conversion into or exchange for stock of the Fund
ranking junior to or on a parity with AMPS as to dividends and upon
liquidation), unless (A) immediately after



                                      7
<PAGE>

such transaction, the Fund would have S&P Eligible Assets and Moody's Eligible
Assets each with an aggregate Discounted Value equal to or greater than the
AMPS Basic Maintenance Amount, and the 1940 Act AMPS Asset Coverage (see
"Asset Maintenance" and "Redemption" below) would be satisfied, (B) full
cumulative dividends on shares of AMPS and shares of the Other AMPS due on or
prior to the date of the transaction have been declared and paid or shall have
been declared and sufficient funds for the payment thereof deposited with the
Auction Agent, (C) any Additional Dividend required to be paid on or before
the date of such declaration or payment has been paid, and (D) the Fund has
redeemed the full number of shares of AMPS required to be redeemed by any
provision for mandatory redemption contained in the Articles Supplementary.

Asset Maintenance

      1940 Act AMPS Asset Coverage. The Fund will be required under the
Articles Supplementary to maintain, with respect to shares of AMPS, as of the
last Business Day of each month in which any shares of AMPS are outstanding,
asset coverage of at least 200% with respect to senior securities that are
stock, including the shares of AMPS and Other AMPS (or such other asset
coverage as in the future may be specified in or under the 1940 Act as the
minimum asset coverage for senior securities that are stock of a closed-end
investment company as a condition of paying dividends on its common stock)
("1940 Act AMPS Asset Coverage"). If the Fund fails to maintain 1940 Act AMPS
Asset Coverage and such failure is not cured as of the last Business Day of
the following month (the "1940 Act Cure Date"), the Fund will be required
under certain circumstances to redeem certain of the shares of AMPS. See
"Description of AMPS--Redemption" in the prospectus and "--Redemption" below.

      AMPS Basic Maintenance Amount. So long as shares of AMPS are
outstanding, the Fund will be required under the Articles Supplementary as of
the last Business Day of each week (a "Valuation Date") to maintain S&P
Eligible Assets and Moody's Eligible Assets each having in the aggregate a
Discounted Value at least equal to the AMPS Basic Maintenance Amount. If the
Fund fails to meet such requirement as of any Valuation Date and such failure
is not cured on or before the sixth Business Day after such Valuation Date
(the "AMPS Basic Maintenance Cure Date"), the Fund will be required under
certain circumstances to redeem certain of the shares of AMPS. See
"Description of AMPS--Redemption" in the prospectus and "--Redemption" below.
Upon any failure to maintain the required Discounted Value, the Fund will use
its best efforts to alter the composition of its portfolio to reattain a
Discounted Value at least equal to the AMPS Basic Maintenance Amount on or
prior to the AMPS Basic Maintenance Cure Date.

      The AMPS Basic Maintenance Amount as of any Valuation Date, means the
dollar amount equal to (i) the sum of (A) the product of the number of shares
of AMPS and Other AMPS outstanding on such Valuation Date multiplied by the
sum of $25,000 and any applicable redemption premium attributable to the
designation of a Premium Call Period; (B) the aggregate amount of cash
dividends (whether or not earned or declared) that will have accumulated for
the AMPS and Other AMPS outstanding to (but not including) the end of the
current Dividend Period for the AMPS that follows such Valuation Date in the
event the then current Dividend Period will end within 49 calendar days of
such Valuation Date or through the 49th day after such Valuation Date in the
event the then current Dividend Period will not end within 49 calendar days of
such Valuation Date; (C) in the event the then current Dividend Period will
end within 49 calendar days of such Valuation Date, the aggregate amount of
cash dividends that would accumulate at the Maximum Applicable Rate applicable
to a Dividend Period of 28 or fewer days on any shares of AMPS and Other AMPS
outstanding from the end of such Dividend Period through the 49th day after
such Valuation Date, multiplied by the larger of the Moody's Volatility Factor
and the S&P Volatility Factor, determined from time to time by Moody's and
S&P, respectively (except that if such Valuation Date occurs during a
Non-Payment Period, the cash dividend for purposes of calculation would
accumulate at the then current Non-Payment Period Rate); (D) the amount of
anticipated expenses of the Fund for the 90 days subsequent to such Valuation
Date; (E) the amount of current outstanding balances of any indebtedness that
is senior to the AMPS, plus interest actually accrued together with 30 days'
additional interest on the current outstanding balances calculated at the
current rate; (F) the amount of the Fund's maximum potential Additional
Dividend liability as of such Valuation Date; and (G) any current liabilities
as of such Valuation Date to the extent not reflected in any of (i)(A) through
(i)(F) (including, without limitation, and immediately upon determination, any
amounts due and payable by the Fund for portfolio securities purchased as of
such Valuation Date and any liabilities incurred for the purpose of clearing
securities transactions) less (ii) either (A) the Discounted Value of any of
the Fund's assets, or (B) the face value of any of the Fund's assets if such
assets mature prior to or on the date of redemption of AMPS or payment of a
liability and are either securities issued or guaranteed by the United States
Government or Deposit Securities, in



                                      8
<PAGE>

both cases irrevocably deposited by the Fund for the payment of the amount
needed to redeem shares of AMPS subject to redemption or to satisfy any of
(i)(B) through (i)(G).

      The Discount Factors and guidelines for determining the market value of
the Fund's portfolio holdings have been based on criteria established in
connection with rating the AMPS. These factors include, but are not limited
to, the sensitivity of the market value of the relevant asset to changes in
interest rates, the liquidity and depth of the market for the relevant asset,
the credit quality of the relevant asset (for example, the lower the rating of
a debt obligation, the higher the related discount factor) and the frequency
with which the relevant asset is marked to market. In no event shall the
Discounted Value of any asset of the Fund exceed its unpaid principal balance
or face amount as of the date of calculation. The Discount Factor relating to
any asset of the Fund and the AMPS Basic Maintenance Amount, the assets
eligible for inclusion in the calculation of the Discounted Value of the
Fund's portfolio and certain definitions and methods of calculation relating
thereto may be changed from time to time by the Fund, without stockholder
approval, but only in the event the Fund receives written confirmation from
S&P, Moody's and any Substitute Rating Agency that any such changes would not
impair the rating then assigned to the shares of AMPS by S&P or Moody's or any
Substitute Rating Agency.

      On or before the seventh Business Day in the case of Moody's and the
next Business Day in the case of S&P after a Valuation Date on which the Fund
fails to maintain S&P Eligible Assets and Moody's Eligible Assets each with an
aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance
Amount, the Fund is required to (i) deliver to Moody's a report with respect
to the calculation of the AMPS Basic Maintenance Amount, the value of its
portfolio holdings and the net asset value and market price of the Fund's
common stock as of the date of such failure (an "AMPS Basic Maintenance
Report") and (ii) send S&P an electronic notification of such failure. The
Fund also will deliver an AMPS Basic Maintenance Report as of the 25th day of
each month (or if such day is not a Business Day, as of the next succeeding
Business Day) or as of the last Business Day of the month in which the Fund's
fiscal year ends on or before the seventh Business Day after such day. Within
ten Business Days after delivery of such report relating to the month in which
the Fund's fiscal year ends, the Fund will deliver a letter prepared by the
Fund's independent accountants regarding the accuracy of the calculations made
by the Fund in such AMPS Basic Maintenance Report. If any such letter prepared
by the Fund's independent accountants shows that an error was made in the AMPS
Basic Maintenance Report, the calculation or determination made by the Fund's
independent accountants will be conclusive and binding on the Fund. The Fund
will also (i) provide Moody's with an AMPS Basic Maintenance Report and (ii)
send S&P an electronic notification, as of each Valuation Date on or before
the seventh Business Day in the case of Moody's and the next Business Day in
the case of S&P after such date when the Discounted Value of Moody's Eligible
Assets or S&P Eligible Assets, as the case may be, fails to exceed the AMPS
Basic Maintenance Amount by 10% or more. Also, on or before 5:00 p.m., Eastern
time, on the first Business Day after shares of common stock are repurchased
by the Fund, the Fund will complete and deliver to Moody's an AMPS Basic
Maintenance Report as of the close of business on such date that common stock
is repurchased.

Redemption

      Mandatory Redemption. The number of shares of AMPS to be redeemed will
be equal to the lesser of (a) the minimum number of shares of AMPS the
redemption of which, if deemed to have occurred immediately prior to the
opening of business on the Cure Date, together with all other shares of the
preferred stock subject to redemption or retirement, would result in the Fund
having S&P Eligible Assets and Moody's Eligible Assets each with an aggregate
Discounted Value equal to or greater than the AMPS Basic Maintenance Amount or
satisfaction of the 1940 Act AMPS Asset Coverage, as the case may be, on such
Cure Date (provided that, if there is no such minimum number of shares the
redemption of which would have such result, all shares of AMPS then
outstanding will be redeemed), and (b) the maximum number of shares of AMPS,
together with all other shares of preferred stock subject to redemption or
retirement, that can be redeemed out of funds expected to be legally available
therefor on such redemption date. In determining the number of shares of AMPS
required to be redeemed in accordance with the foregoing, the Fund shall
allocate the number required to be redeemed which would result in the Fund
having S&P Eligible Assets and Moody's Eligible Assets each with an aggregate
Discounted Value equal to or greater than the AMPS Basic Maintenance Amount or
satisfaction of the 1940 Act AMPS Asset Coverage, as the case may be, pro rata
among shares of AMPS, Other AMPS and other preferred stock subject to
redemption pursuant to provisions similar to those set forth below; provided
that, shares of AMPS which may not be redeemed at the option of the Fund due
to the designation of a Non-Call Period applicable to such shares (A) will be
subject to mandatory



                                      9
<PAGE>

redemption only to the extent that other shares are not available to satisfy
the number of shares required to be redeemed and (B) will be selected for
redemption in an ascending order of outstanding number of days in the Non-Call
Period (with shares with the lowest number of days to be redeemed first) and
by lot in the event of shares having an equal number of days in such Non-Call
Period. The Fund is required to effect such a mandatory redemption on a
Business Day which is not later than 30 days after such Cure Date, except that
if the Fund does not have funds legally available for the redemption of all of
the required number of shares of AMPS and shares of other preferred stock
which are subject to mandatory redemption or the Fund otherwise is unable to
effect such redemption on a Business Day which is on or prior to 30 days after
such Cure Date, the Fund will redeem those shares of AMPS that it was unable
to redeem on the earliest practicable date on which it is able to effect such
redemption out of funds legally available therefor.

      Notice of Redemption. If shares of AMPS are to be redeemed, a notice of
redemption will be mailed to each record holder of such shares of AMPS
(initially Cede as nominee of the Securities Depository) and to the Auction
Agent not less than 17 nor more than 60 days prior to the date fixed for the
redemption thereof. Each notice of redemption will include a statement setting
forth: (i) the redemption date, (ii) the redemption price, (iii) the aggregate
number of shares of AMPS to be redeemed, (iv) the place or places where shares
of AMPS are to be surrendered for payment of the redemption price, (v) a
statement that dividends on the shares to be redeemed will cease to accumulate
on such redemption date (except that holders may be entitled to Additional
Dividends) and (vi) the provision of the Articles Supplementary pursuant to
which such shares are being redeemed. The notice also will be published in the
eastern and national editions of The Wall Street Journal. No defect in the
notice of redemption or in the mailing or publication thereof will affect the
validity of the redemption proceedings, except as required by applicable law.

      In the event that less than all of the outstanding shares of AMPS are to
be redeemed, the shares to be redeemed will be selected by lot or such other
method as the Fund shall deem fair and equitable, and the results thereof will
be communicated to the Auction Agent. The Auction Agent will give notice to
the Securities Depository, whose nominee will be the record holder of all
shares of AMPS, and the Securities Depository will determine the number of
shares to be redeemed from the account of the Agent Member of each Existing
Holder. Each Agent Member will determine the number of shares to be redeemed
from the account of each Existing Holder for which it acts as agent. An Agent
Member may select for redemption shares from the accounts of some Existing
Holders without selecting for redemption any shares from the accounts of other
Existing Holders. Notwithstanding the foregoing, if neither the Securities
Depository nor its nominee is the record holder of all of the shares of AMPS,
the particular shares to be redeemed shall be selected by the Fund by lot or
by such other method as the Fund shall deem fair and equitable.

      If the Fund gives notice of redemption, and concurrently or thereafter
deposits in trust with the Auction Agent, or segregates in an account at the
Fund's custodian bank for the benefit of the holders of the AMPS to be
redeemed and for payment to the Auction Agent, Deposit Securities (with a
right of substitution) having an aggregate Discounted Value equal to the
redemption payment for the shares of AMPS as to which notice of redemption has
been given, with irrevocable instructions and authority to pay the redemption
price to the record holders thereof, then upon the date of such deposit or, if
no such deposit is made, upon such date fixed for redemption (unless the Fund
shall default in making payment of the redemption price), all rights of the
holders of such shares called for redemption will cease and terminate, except
the right of such holders to receive the redemption price in respect thereof
and any Additional Dividends, but without interest, and such shares no longer
will be deemed to be outstanding. The Fund will be entitled to receive, from
time to time, the interest, if any, earned on such Deposit Securities
deposited with the Auction Agent, and the holders of any shares so redeemed
will have no claim to any such interest. Any funds so deposited which are
unclaimed at the end of one year from such redemption date will be repaid,
upon demand, to the Fund, after which the holders of the shares of AMPS so
called for redemption may look only to the Fund for payment thereof.

      So long as any shares of AMPS are held of record by the nominee of the
Securities Depository (initially Cede), the redemption price for such shares
will be paid on the redemption date to the nominee of the Securities
Depository. The Securities Depository's normal procedures now provide for it
to distribute the amount of the redemption price to Agent Members who, in
turn, are expected to distribute such funds to the persons for whom they are
acting as agent. Notwithstanding the provisions for redemption described
above, no shares of AMPS shall be subject to optional redemption (i) unless
all dividends in arrears on the outstanding shares of AMPS, and all capital



                                      10
<PAGE>

stock of the Fund ranking on a parity with the AMPS with respect to the
payment of dividends or upon liquidation, including the Other AMPS, have been
or are being contemporaneously paid or declared and set aside for payment and
(ii) if redemption thereof would result in the Fund's failure to maintain
Moody's Eligible Assets or S&P Eligible Assets with an aggregate Discounted
Value equal to or greater than the AMPS Basic Maintenance Amount.

Voting Rights

      In connection with the election of the Fund's directors, holders of
shares of AMPS, Other AMPS and any other preferred stock, voting separately as
a single class, shall be entitled at all times to elect two of the Fund's
directors, and the remaining directors will be elected by holders of shares of
common stock and shares of AMPS, Other AMPS and any other preferred stock,
voting together as a single class. In addition, if at any time dividends on
outstanding shares of AMPS shall be unpaid in an amount equal to at least two
full years' dividends thereon or if at any time holders of any shares of
preferred stock, including Other AMPS, are entitled, together with the holders
of AMPS, to elect a majority of the directors of the Fund under the 1940 Act,
then the number of directors constituting the Board of Directors automatically
shall be increased by the smallest number that, when added to the two
directors elected exclusively by the holders of shares of AMPS, Other AMPS and
any other preferred stock as described above, would constitute a majority of
the Board of Directors as so increased by such smallest number, and at a
special meeting of stockholders which will be called and held as soon as
practicable, and at all subsequent meetings at which directors are to be
elected, the holders of shares of AMPS, Other AMPS and any other preferred
stock, voting as a separate class, will be entitled to elect the smallest
number of additional directors that, together with the two directors that such
holders in any event will be entitled to elect, constitutes a majority of the
total number of directors of the Fund as so increased. The terms of office of
the persons who are directors at the time of that election will continue. If
the Fund thereafter shall pay, or declare and set apart for payment in full,
all dividends payable on all outstanding shares of AMPS and any other
preferred stock, including Other AMPS, for all past Dividend Periods, the
additional voting rights of the holders of shares of AMPS and any other
preferred stock, including Other AMPS, as described above shall cease, and the
terms of office of all of the additional directors elected by the holders of
shares of AMPS, Other AMPS and any other preferred stock (but not of the
directors with respect to whose election the holders of common stock were
entitled to vote or the two directors the holders of shares of AMPS, Other
AMPS and any other preferred stock have the right to elect in any event) will
terminate automatically.

      The affirmative vote of a majority of the votes entitled to be cast by
holders of outstanding shares of AMPS and any other preferred stock, including
Other AMPS, voting as a separate class, will be required to (i) authorize,
create or issue any class or series of stock ranking prior to the AMPS or any
other series of preferred stock with respect to the payment of dividends or
the distribution of assets on dissolution, liquidation or winding up the
affairs of the Fund, or (ii) amend, alter or repeal the provisions of the
Charter, whether by merger, consolidation or otherwise, so as to adversely
affect any of the contract rights expressly set forth in the Charter of
holders of shares of AMPS or any other preferred stock. To the extent
permitted under the 1940 Act, in the event shares of more than one series of
preferred stock are outstanding, the Fund shall not approve any of the actions
set forth in clause (i) or (ii) which adversely affects the contract rights
expressly set forth in the Charter of a holder of shares of AMPS differently
than those of a holder of shares of any other series of preferred stock
without the affirmative vote of at least a majority of votes entitled to be
cast by holders of the shares of AMPS adversely affected and outstanding at
such time (voting separately as a class). The Board of Directors, however,
without stockholder approval, may amend, alter or repeal any or all of the
various rating agency guidelines described herein in the event the Fund
receives confirmation from the rating agencies that any such amendment,
alteration or repeal would not impair the ratings then assigned to shares of
AMPS. Furthermore, the Board of Directors, without stockholder approval, may
terminate compliance with the Moody's or S&P guidelines as discussed under
"Rating Agency Guidelines" in the prospectus. Unless a higher percentage is
provided for under "Description of Capital Stock--Certain Provisions of the
Charter and By-laws" in the prospectus, the affirmative vote of the holders of
a majority of the outstanding shares of preferred stock (as defined under
"Investment Restrictions"), including AMPS and Other AMPS, entitled to be
cast, voting as a separate class, will be required to approve any plan of
reorganization (including bankruptcy proceedings) adversely affecting such
shares or any action requiring a vote of security holders under Section 13(a)
of the 1940 Act including, among other things, changes in the Fund's
investment objective or changes in the investment policies and restrictions
described as fundamental policies in the prospectus and under "Investment
Restrictions." So long as any shares of AMPS are outstanding, the affirmative
vote of the holders of a majority of the outstanding shares of preferred stock
(as defined under "Investment Restrictions"), including AMPS and Other



                                      11
<PAGE>

AMPS, voting together as a single class, will be required to approve any
voluntary application by the Fund for relief under Federal bankruptcy law or
any similar application under state law for so long as the Fund is solvent and
does not foresee becoming insolvent. The class vote of holders of shares of
AMPS, Other AMPS and any other preferred stock described above in each case
will be in addition to a separate vote of the requisite percentage of shares
of common stock and shares of AMPS, Other AMPS and any other preferred stock,
voting together as a single class, necessary to authorize the action in
question. An increase in the number of authorized shares of preferred stock
pursuant to the Charter or the issuance of additional shares of any series of
preferred stock (including AMPS and Other AMPS) pursuant to the Charter shall
not in and of itself be considered to adversely affect the contract rights of
the holders of the AMPS.

      Notwithstanding the foregoing, and except as otherwise required by the
1940 Act, (i) holders of outstanding shares of the AMPS will be entitled as a
series, to the exclusion of the holders of all other securities, including
other preferred stock, common stock and other classes of capital stock of the
Fund, to vote on matters affecting the AMPS that do not materially adversely
affect any of the contract rights of holders of such other securities,
including other preferred stock, common stock and other classes of capital
stock, as expressly set forth in the Charter, and (ii) holders of outstanding
shares of AMPS will not be entitled to vote on matters affecting any other
preferred stock that do not materially adversely affect any of the contract
rights of holders of the AMPS, as expressly set forth in the Charter.

      The foregoing voting provisions will not apply to any shares of AMPS if,
at or prior to the time when the act with respect to which such vote otherwise
would be required shall be effected, such shares shall have been (i) redeemed
or (ii) called for redemption and sufficient funds shall have been deposited
in trust to effect such redemption.

                                  THE AUCTION

Auction Agent Agreement

      The Auction Agent will act as agent for the Fund in connection with
Auctions. In the absence of bad faith or negligence on its part, the Auction
Agent will not be liable for any action taken, suffered or omitted, or for any
error of judgment made, by it in the performance of its duties under the
Auction Agent Agreement, and will not be liable for any error of judgment made
in good faith unless the Auction Agent shall have been negligent in
ascertaining, or failing to ascertain, the pertinent facts. Pursuant to the
Auction Agent Agreement, the Fund is required to indemnify the Auction Agent
for certain losses and liabilities incurred by the Auction Agent without
negligence or bad faith on its part in connection with the performance of its
duties under such agreement.

      The Auction Agent may terminate the Auction Agent Agreement upon notice
to the Fund, which termination may be no earlier than 60 days following
delivery of such notice. If the Auction Agent resigns, the Fund will use its
best efforts to enter into an agreement with a successor Auction Agent
containing substantially the same terms and conditions as the Auction Agent
Agreement. The Fund may terminate the Auction Agent Agreement at any time,
provided that prior to such termination the Fund shall have entered into such
an agreement with respect thereto with a successor Auction Agent.

Broker-Dealer Agreements

      The Auctions require the participation of one or more broker-dealers. A
Broker-Dealer Agreement may be terminated by the Auction Agent or a
Broker-Dealer on five days' notice to the other party, provided that the
Broker-Dealer Agreement with Merrill Lynch may not be terminated without the
prior written consent of the Fund, which consent may not be unreasonably
withheld.

      For the fiscal years ended April 30, 2005, 2004 and 2003, Merrill Lynch,
an affiliate of the Investment Adviser, earned $168,937, $145,785 and
$175,133, respectively, pursuant to its Broker-Dealer Agreement with the Fund.

                           RATING AGENCY GUIDELINES

      S&P AAA Rating Guidelines The Discounted Value of the Fund's S&P
Eligible Assets is calculated on each Valuation Date. See "Description of
AMPS--Asset Maintenance--AMPS Basic Maintenance Amount." S&P Eligible Assets
include cash, Receivables for Municipal Bonds Sold (as defined below), Rule
2a-7 Money Market Funds and Municipal Bonds eligible for consideration under
S&P's current guidelines. For purposes of calculating the Discounted Value of
the Fund's portfolio under current S&P guidelines, the fair market value of
Municipal Bonds eligible for consideration under such guidelines must be
discounted by the applicable S&P Discount Factor set forth in the table below.
The Discounted Value of a Municipal Bond eligible for consideration under S&P
guidelines is the fair market value thereof divided by the S&P Discount
Factor. The S&P Discount Factor used to discount a particular Municipal Bond
will be determined by reference to the rating by S&P, Moody's or Fitch on such
Municipal Bond; provided, however, for purposes of determining the S&P
Discount Factor applicable to Municipal Bonds not rated by S&P, the Municipal
Bonds will carry an S&P rating one full rating category lower than the S&P
rating category that is the equivalent of the rating category in which such
Municipal Bond is placed by a NRSRO, in accordance with the table set forth
below:

*     S&P rating.

**    Not rated.

(1)   For Municipal Bonds of any one issuer rated at least BBB- by S&P, or if
      not rated by S&P, rated at least A- by another NRSRO, 2% is added to the
      applicable S&P Discount Factor for every 1% by which the fair market
      value of such Municipal Bonds exceeds 5% of the aggregate fair market
      value of the S&P Eligible Assets, but in no event greater than 10%; or
      for any percentage over 5% add 10 percentage points to the applicable
      S&P Discount Factor.

(2)   For zero coupon Municipal Bonds, the S&P Discount Factor is 441.80%.

      Notwithstanding the foregoing, (i) the S&P Discount Factor for
short-term Municipal Bonds will be 115%, so long as such Municipal Bonds are
rated A-1+ or SP-1+ by S&P and mature or have a demand feature exercisable in
30 days or less, or 120% so long as such Municipal Bonds are rated A-1 or SP-1
by S&P and mature or have a demand feature exercisable in 30 days or less, or
125% if such Municipal Bonds are not rated by S&P but are rated VMIG-1, P-1 or
MIG-1 by Moody's or F-1+ by Fitch; provided, however, such short-term
Municipal Bonds rated by Moody's or Fitch but not rated by S&P having a demand
feature exercisable in 30 days or less must be backed by a letter of credit,
liquidity facility or guarantee from a bank or other financial institution
having a short-term rating of at least A-1+ from S&P; and further provided
that such short-term Municipal Bonds rated by Moody's or Fitch but not rated
by S&P may comprise no more than 50% of short-term Municipal Bonds that
qualify as S&P Eligible Assets, (ii) the S&P Discount Factor for Rule 2a-7
Money Market Funds will be 110%, (iii) the S&P Discount Factor for Receivables
for Municipal Bonds Sold that are due in more than five Business Days from
such Valuation Date will be the S&P Discount Factor applicable to the
Municipal Bonds sold and (iv) no S&P Discount Factor will be applied to cash
or to Receivables for Municipal Bonds Sold if such receivables are due within
five Business Days of such Valuation Date. "Receivables for Municipal Bonds
Sold," for purposes of calculating S&P Eligible Assets as of any Valuation
Date, means the book value of receivables for Municipal Bonds sold as of or
prior to such Valuation Date. For purposes of the foregoing, Anticipation
Notes rated SP-1 or, if not rated by S&P, rated VMIG-1 by Moody's or F-1+ by
Fitch, which do not mature or have a demand feature exercisable in 30 days and
which do not have a long-term rating, shall be considered to be short-term
Municipal Bonds.

<PAGE>

      The S&P guidelines require certain minimum issue size and impose other
requirements for purposes of determining S&P Eligible Assets. In order to be
considered S&P Eligible Assets, Municipal Bonds must:

            (i) be issued by any of the 50 states of the United States, its
      territories and their subdivisions, counties, cities, towns, villages,
      and school districts, agencies, such as authorities and special
      districts created by the states, and certain federally sponsored
      agencies such as local housing authorities (payments made on these bonds
      are exempt from regular Federal income taxes and are generally exempt
      from state and local taxes in the state of issuance);

            (ii) except for zero coupon Municipal Bonds rated AAA by S&P that
      mature in 30 years or less, be interest bearing and pay interest at
      least semi-annually;

            (iii) be payable with respect to principal and interest in U.S.
      dollars; (a) not be subject to a covered call or covered put option
      written by the Fund; (b) except for Inverse Floaters, not be part of a
      private placement; and

            (iv) except for Inverse Floaters and legally defeased bonds that
      are secured by securities issued or guaranteed by the United States
      Government, be part of an issue with an original issue size of at least
      $10 million or, if of an issue with an original issue size below $10
      million, is rated at least AA or higher by S&P.

      Notwithstanding the foregoing:

            (i) Municipal Bonds issued by issuers in any one state or
      territory will be considered S&P Eligible Assets only to the extent the
      fair market value of such Municipal Bonds does not exceed 25% of the
      aggregate fair market value of S&P Eligible Assets;

            (ii) Municipal Bonds which are escrow bonds or defeased bonds may
      compose up to 100% of the aggregate fair market value of S&P Eligible
      Assets if such Bonds initially are assigned a rating by S&P in
      accordance with S&P's legal defeasance criteria or rerated by S&P as
      economic defeased escrow bonds and assigned an AAA rating. Municipal
      Bonds may be rated as escrow bonds by another NRSRO or rerated as an
      escrow bond and assigned the equivalent of an S&P AAA rating, provided
      that such equivalent rated Bonds are limited to 50% of the aggregate
      fair market value of S&P Eligible Assets and are deemed to have an AA
      S&P rating for purposes of determining the S&P Discount Factor
      applicable to such Municipal Bonds. The limitations on Municipal Bonds
      in clause (i) above and clauses (iii) and (iv) below are not applicable
      to escrow bonds;

            (iii) Municipal Bonds which are not rated by any NRSRO may
      comprise no more than 10% of S&P Eligible Assets;

            (iv) Municipal Bonds rated at least BBB- by S&P, or if not rated
      by S&P, rated at least A- by another NRSRO, of any one issuer or
      guarantor (excluding bond insurers) will be considered S&P Eligible
      Assets only to the extent the fair market value of such Municipal Bonds
      does not exceed 10% of the aggregate fair market value of the S&P
      Eligible Assets, High Yield Municipal Bonds of any issuer may comprise
      no more than 5% of S&P Eligible Assets, and Municipal Bonds of any one
      issuer which are not rated by any NRSRO will be considered S&P Eligible
      Assets only to the extent the fair market value of such Municipal Bonds
      does not exceed 5% of the aggregate fair market value of the S&P
      Eligible Assets. In the aggregate, the maximum issuer exposure is
      limited to 10% of the S&P Eligible Assets; and

            (v) Municipal Bonds not rated by S&P but rated by another NRSRO
      will be included in S&P Eligible Assets only to the extent the fair
      market value of such Municipal Bonds does not exceed 50% of the
      aggregate fair market value of the S&P Eligible Assets.

      As discussed in the prospectus, the Fund may engage in options or
futures transactions. For so long as any shares of AMPS are rated by S&P, the
Fund will not purchase or sell financial futures contracts, write, purchase or



                                      14
<PAGE>

sell options on financial futures contracts or write put options (except
covered put options) or call options (except covered call options) on
portfolio securities unless it receives written confirmation from S&P that
engaging in such transactions will not impair the ratings then assigned to the
shares of AMPS by S&P, except that the Fund may purchase or sell financial
futures contracts based on the Bond Buyer Municipal Bond Index (the "Municipal
Index") or Treasury Bonds and write, purchase or sell put and call options on
such contracts (collectively, "S&P Hedging Transactions"), subject to the
following limitations:

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

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

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

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

            (v) when the Fund writes a financial futures contract or an option
      thereon, it will either maintain an amount of cash, cash equivalents or
      liquid assets in a segregated account with the Fund's custodian, so that
      the amount so segregated plus the amount of Initial Margin and Variation
      Margin held in the account of or on behalf of the Fund's broker with
      respect to such financial futures contract or option equals the fair
      market value of the financial futures contract or option, or, in the
      event the Fund writes a financial futures contract or option thereon
      that requires delivery of an underlying security, it shall hold such
      underlying security in its portfolio.

      For purposes of determining whether the Fund has S&P Eligible Assets
with a Discounted Value that equals or exceeds the AMPS Basic Maintenance
Amount, the Discounted Value of cash or securities held for the payment of
Initial Margin or Variation Margin shall be zero and the aggregate Discounted
Value of S&P Eligible Assets shall be reduced by an amount equal to (i) 30% of
the aggregate settlement value, as marked to market, of any outstanding
financial futures contracts based on the Municipal Index that are owned by the
Fund plus (ii) 25% of the aggregate settlement value, as marked to market, of
any outstanding financial futures contracts based on Treasury Bonds which
contracts are owned by the Fund.

Moody's Aaa Rating Guidelines

      The Discounted Value of the Fund's Moody's Eligible Assets is calculated
on each Valuation Date. See "Description of AMPS--Asset Maintenance--AMPS
Basic Maintenance Amount." Moody's Eligible Assets



                                      15
<PAGE>

include cash, Receivables for Municipal Bonds Sold (as defined below), Rule
2a-7 Money Market Funds and Municipal Bonds eligible for consideration under
Moody's guidelines. For purposes of calculating the Discounted Value of the
Fund's portfolio under current Moody's guidelines, the fair market value of
Municipal Bonds eligible for consideration under such guidelines must be
discounted by the applicable Moody's Discount Factor set forth in the table
below. The Discounted Value of a Municipal Bond eligible for consideration
under Moody's guidelines is the lower of par and the quotient of the fair
market value thereof divided by the Moody's Discount Factor. The Moody's
Discount Factor used to discount a particular Municipal Bond will be
determined by reference to the rating by Moody's, S&P or Fitch on such
Municipal Bond, in accordance with the tables set forth below:


                          Moody's Rating Category (1)
-------------------------------------------------------------------------------
      Aaa              Aa               A              Baa          Other (2)
----------------  --------------  -------------- -------------   --------------
      151%            159%            160%            173%            225%

----------
(1)   Ratings assigned by S&P or Fitch are generally accepted by Moody's at
      face value. However, adjustments to face value may be made to particular
      categories of credits for which the S&P and/or Fitch rating does not
      seem to approximate a Moody's rating equivalent. Split rated securities
      assigned by S&P and Fitch will be accepted at the lower of the two
      ratings.

(2)   Municipal Bonds rated Ba1 to B3 by Moody's or, if not rated by Moody's,
      rated BB+ to B- by S&P or Fitch. In addition, Municipal Bonds not
      explicitly rated by Moody's, S&P or Fitch, but rated at least the
      equivalent of B3 internally by the Investment Adviser, provided that
      Moody's reviews and achieves sufficient comfort with the Investment
      Adviser's internal credit rating processes, will be included under
      "Other" in the table. Unless conclusions regarding liquidity risk as
      well as estimates of both the probability and severity of default for
      the Fund's assets can be derived from other sources as well as combined
      with a number of sources as presented by the Fund to Moody's, unrated
      Municipal Bonds which are rated at least the equivalent of B3 by the
      Investment Adviser internally are limited to 10% of Moody's Eligible
      Assets.

                            Moody's Rating Category
------------------------------------------------------------------------------
         MIG-1, VMIG-1, P-1 (1)                  MIG-1, VMIG-1, P-1 (2)

                  100%                                    136%
----------
(1)   Moody's rated Municipal Bonds that have a maturity less than or equal to
      49 days and Municipal Bonds not rated by Moody's but rated the
      equivalent to MIG-1, VMIG-1, or P-1 by S&P or Fitch that have a maturity
      less than or equal to 49 days.

(2)   Moody's rated Municipal Bonds that have a maturity greater than 49 days
      and Municipal Bonds not rated by Moody's but rated the equivalent to
      MIG-1, VMIG-1, or P-1 by S&P or Fitch that have a maturity greater than
      49 days.

      Notwithstanding the foregoing, no Moody's Discount Factor will be
applied to cash or to Receivables for Municipal Bonds Sold that are due within
five Business Days of such Valuation Date. The Moody's Discount Factor for
Receivables for Municipal Bonds Sold that are due within six and 30 Business
Days of such Valuation Date will be the Moody's Discount Factor applicable to
the Municipal Bonds sold. "Receivables for Municipal Bonds Sold," for purposes
of calculating Moody's Eligible Assets as of any Valuation Date, means the
book value of receivables for Municipal Bonds sold as of or prior to such
Valuation Date if such receivables are due within 30 Business Days of such
Valuation Date.

      The Moody's Discount Factor for Inverse Floaters shall be the product of
(x) the percentage determined by reference to the rating on the security
underlying such Inverse Floaters multiplied by (y) 1.25.

      The Moody's Discount Factor for Rule 2a-7 Money Market Funds shall be
110%.

      The Moody's guidelines impose certain requirements as to minimum issue
size, issuer diversification and geographical concentration, as well as other
requirements for purposes of determining whether Municipal Bonds constitute
Moody's Eligible Assets, as set forth in the table on the following page:

                     Minimum Issue Size  Maximum Underlying     Maximum State
       Rating           ($ Millions)       Obligor (%) (1)   Allowed (%) (1) (3)
------------------- -------------------- ------------------  -------------------
        Aaa                   *                  100                 100
         Aa                  10                  20                  60
         A                   10                  10                  40

     Other (2)               10                   2                  12
----------
*     Not applicable.

(1)   The referenced percentages represent maximum cumulative totals for the
      related rating category and each lower rating category.

(2)   Municipal Bonds not rated by Moody's, S&P or Fitch, but rated at least
      the equivalent of B3 internally by the Investment Adviser.

(3)   Territorial bonds (other than those issued by Puerto Rico and counted
      collectively) are each limited to 10% of Moody's Eligible Assets. For
      diversification purposes, Puerto Rico will be treated as a state.

      For purposes of the maximum underlying obligor requirement described
above, any Municipal Bond backed by the guaranty, letter of credit or
insurance issued by a third party will be deemed to be issued by such third
party if the issuance of such third party credit is the sole determinant of
the rating on such Bond.

      Current Moody's guidelines also require that Municipal Bonds
constituting Moody's Eligible Assets pay interest in cash, are publicly rated
B3 or higher by Moody's or, if not rated by Moody's, but rated by S&P or
Fitch, are publicly rated at least B- by S&P or Fitch, or if not explicitly
rated by Moody's, S&P or Fitch, be rated at least the equivalent of B3
internally by the Investment Adviser, provided that Moody's reviews and
achieves sufficient comfort with the Investment Adviser's internal credit
rating processes, not have suspended ratings by Moody's, if an Inverse
Floater, be explicitly rated by Moody's, and be part of an issue of Municipal
Bonds of at least $10,000,000 (except for issues rated Aaa by Moody's, as
provided in the chart above).

      When the Fund sells a Municipal Bond and agrees to repurchase it at a
future date, the Discounted Value of such Municipal Bond will constitute a
Moody's Eligible Asset and the amount the Fund is required to pay upon
repurchase of such Bond will count as a liability for purposes of calculating
the AMPS Basic Maintenance Amount. For so long as the AMPS are rated by
Moody's, the Fund will not enter into any such reverse repurchase agreements
unless it has received written confirmation from Moody's that such
transactions would not impair the rating then assigned the AMPS by Moody's.
When the Fund purchases a Municipal Bond and agrees to sell it at a future
date to another party, cash receivable by the Fund thereby will constitute a
Moody's Eligible Asset if the long-term debt of such other party is rated at
least A2 by Moody's and such agreement has a term of 30 days or less;
otherwise the Discounted Value of such Bond will constitute a Moody's Eligible
Asset.

      High Yield Municipal Bonds may comprise no more than 20% of Moody's
Eligible Assets. Unless conclusions regarding liquidity risk as well as
estimates of both the probability and severity of default for the Fund's
assets can be derived from other sources as well as combined with a number of
sources as presented by the Fund to Moody's, unrated High Yield Municipal
Bonds which are rated at least the equivalent of B3 by the Investment Adviser
internally are limited to 10% of Moody's Eligible Assets.

      Inverse Floaters, including primary market and secondary market residual
interest bonds, may constitute no more than 10% of Moody's Eligible Assets.



                                      17
<PAGE>

      Notwithstanding the foregoing, an asset will not be considered a Moody's
Eligible Asset if it is (i) held in a margin account, (ii) subject to any
material lien, mortgage, pledge, security interest or security agreement of
any kind, (iii) held for the purchase of a security pursuant to a Forward
Commitment or (iv) irrevocably deposited by the Fund for the payment of
dividends or redemption.

      For so long as shares of AMPS are rated by Moody's, in managing the
Fund's portfolio, the Investment Adviser will not alter the composition of the
Fund's portfolio if, in the reasonable belief of the Investment Adviser, the
effect of any such alteration would be to cause the Fund to have Moody's
Eligible Assets with an aggregate Discounted Value, as of the immediately
preceding Valuation Date, less than the AMPS Basic Maintenance Amount as of
such Valuation Date; provided, however, that in the event that, as of the
immediately preceding Valuation Date, the aggregate Discounted Value of
Moody's Eligible Assets exceeded the AMPS Basic Maintenance Amount by 5% or
less, the Investment Adviser will not alter the composition of the Fund's
portfolio in a manner reasonably expected to reduce the aggregate Discounted
Value of Moody's Eligible Assets unless the Fund shall have confirmed that,
after giving effect to such alteration, the aggregate Discounted Value of
Moody's Eligible Assets would exceed the AMPS Basic Maintenance Amount.

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

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

            (ii) the Fund will not engage in any Moody's Hedging Transaction
      based on Treasury Bonds (other than Closing Transactions) that would
      cause the Fund at the time of such transaction to own or have sold (A)
      outstanding financial futures contracts based on Treasury Bonds having
      an aggregate fair market value exceeding 40% of the aggregate fair
      market value of Moody's Eligible Assets owned by the Fund and rated Aa
      by Moody's (or, if not rated by Moody's but rated by S&P, rated AAA by
      S&P) or (B) outstanding financial futures contracts based on Treasury
      Bonds having an aggregate fair market value exceeding 80% of the
      aggregate fair market value of all Municipal Bonds constituting Moody's
      Eligible Assets owned by the Fund (other than Moody's Eligible Assets
      already subject to a Moody's Hedging Transaction) and rated Baa or A by
      Moody's (or, if not rated by Moody's but rated by S&P, rated A or AA by
      S&P) (for purposes of the foregoing clauses (i) and (ii), the Fund shall
      be deemed to own the number of financial futures contracts that underlie
      any outstanding options written by the Fund);

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

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



                                      18
<PAGE>

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

            (vi) the Fund (A) will not engage in options and futures
      transactions for leveraging or speculative purposes, except that the
      Fund may engage in an option or futures transaction so long as the
      combination of the Fund's non-derivative positions, together with the
      relevant option or futures transaction, produces a synthetic investment
      position, or the same economic result, that could be achieved by an
      investment, consistent with the Fund's investment objective and
      policies, in a security that is not an option or futures transaction,
      subject to the Investment Adviser periodically demonstrating to Moody's
      that said economic results are achieved, and (B) will not write any call
      options or sell any financial futures contracts for the purpose of
      hedging the anticipated purchase of an asset prior to completion of such
      purchase;

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

            (viii) the Fund will not engage in BMA swap transactions with
      respect to more than 20% of the Fund's net assets; provided that the
      Fund's use of futures will proportionately decrease as the Fund's use of
      BMA swap transactions increases, and vice-versa.

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

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

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

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



                                      19
<PAGE>

      income securities with a Discounted Value that equals or exceeds the
      amount of the Fund's obligations under any Forward Commitment to which it
      is from time to time a party, and

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

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

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

      For so long as shares of AMPS are rated by S&P or Moody's, the Fund,
unless it has received written confirmation from S&P and/or Moody's, as the
case may be, that such action would not impair the ratings then assigned to
the AMPS by S&P and/or Moody's, as the case may be, will not (i) borrow money
except for the purpose of clearing transactions in portfolio securities (which
borrowings under any circumstances shall be limited to the lesser of $10
million and an amount equal to 5% of the fair market value of the Fund's
assets at the time of such borrowings and which borrowings shall be repaid
within 60 days and not be extended or renewed and shall not cause the
aggregate Discounted Value of Moody's Eligible Assets and S&P Eligible Assets
to be less than the AMPS Basic Maintenance Amount), (ii) engage in short sales
of securities, (iii) lend any securities, (iv) issue any class or series of
stock ranking prior to or on a parity with the AMPS with respect to the
payment of dividends or the distribution of assets upon dissolution,
liquidation or winding up of the Fund, (v) reissue any securities previously
purchased or redeemed by the Fund, (vi) merge or consolidate into or with any
other corporation or entity, (vii) change the Fund's pricing service or (viii)
engage in reverse repurchase agreements.

      For as long as the AMPS are rated by S&P, the Fund will not, unless it
has received written confirmation from S&P that such action would not impair
the rating then assigned to the shares of AMPS by S&P, engage in interest rate
swaps, caps and floors, except that the Fund may, without obtaining the
written consent described above, engage in swaps, caps and floors if: (i) the
counterparty to the swap transaction has a short-term rating of A-1 or, if the
counterparty does not have a short-term rating, the counterparty's senior
unsecured long-term debt rating is A- or higher, (ii) the original aggregate
notional amount of the interest rate swap transaction or transactions is not
to be greater than the liquidation preference of the AMPS, (iii) the interest
rate swap transaction will be marked-to-market weekly by the swap
counterparty, (iv) if the Fund fails to maintain an aggregate discounted value
at least equal to the AMPS Basic Maintenance Amount on two consecutive
Valuation Dates then the agreement shall terminate immediately, (v) for the
purpose of calculating the Discounted Value of S&P Eligible Assets, 90% of any
positive mark-to-market valuation of the Fund's rights will be S&P Eligible
Assets, 100% of any negative mark-to-market valuation of the Fund's rights
will be included in the calculation of the AMPS Basic Maintenance Amount, and
(vi) the Fund must maintain liquid assets with a value at least equal to the
net amount of the excess, if any, of the Fund's obligations over its
entitlement with respect to each swap. For caps/floors, the Fund must maintain
liquid assets with a value at least equal to the Fund's obligations with
respect to such caps or floors.

                            DIRECTORS AND OFFICERS

      The Directors of the Fund consist of seven individuals, six of whom are
not "interested persons" of the Fund as defined in the 1940 Act (the
"non-interested Directors" or "independent Directors"). The Directors are
responsible for the oversight of the operations of the Fund and perform the
various duties imposed on the directors of investment companies by the 1940
Act.

      Each non-interested Director is a member of the Fund's Audit Committee
(the "Audit Committee"). The principal responsibilities of the Audit Committee
are the appointment, compensation, retention and oversight of the Fund's
independent registered public accounting firm, including the resolution of
disagreements regarding financial reporting between Fund management and such
independent registered public accounting firm. The Audit Committee's
responsibilities include, without limitation, to (i) review with the
independent registered public accounting firm the arrangements for and scope
of annual and special audits and any other services provided by the
independent registered public accounting firm to the Fund; (ii) review with
the independent registered public accounting firm any audit problems or
difficulties encountered during or relating to the conduct of the audit; (iii)
ensure that the independent registered public accounting firm submits on a
periodic basis a formal written statement with respect to their independence,
discuss with the independent registered public accounting firm any
relationships or services that may impact the objectivity and independence of
the Fund's independent registered public accounting firm; and (iv) consider
information and comments of the independent registered public accounting firm
with respect to the Fund's accounting and financial reporting policies,
procedures and internal control over financial reporting and Fund management's
responses thereto. The Board of Directors of the Fund has adopted a written
charter for the Audit Committee. The Audit Committee has retained independent
legal counsel to assist it in connection with these duties. The Audit
Committee met four times during the Fund's fiscal year ended April 30, 2005.

      Cynthia A. Montgomery and Edward D. Zinbarg are the members of the
Fund's Nominating Committee (the "Nominating Committee"). The principal
responsibilities of the Nominating Committee are to identify individuals
qualified to serve as non-interested Directors of the Fund and to recommend
its nominees for consideration by the full Board. While the Nominating
Committee is solely responsible for the selection and nomination of the Fund's
non-interested Directors, the Nominating Committee may consider nominations
for the office of the Director made by Fund stockholders as it deems
appropriate. Fund stockholders who wish to recommend a nominee should send
nominations to the Secretary of the Fund that include biographical information
and set forth the qualifications of the proposed nominee. The Nominating
Committee met once during the Fund's fiscal year ended April 30, 2005.

Biographical Information

      Certain biographical and other information relating to the
non-interested Directors of the Fund is set forth below, including their ages,
their principal occupations for at least the last five years, the length of
time served, the total number of portfolios overseen in the complex of funds
advised by the Investment Adviser, Merrill Lynch Investment Managers, L.P.
("MLIM") or their affiliates ("MLIM/FAM-advised funds") and other public
directorships.

               INVESTMENT ADVISORY AND MANAGEMENT ARRANGEMENTS

      The Investment Adviser, which is owned and controlled by ML & Co., a
financial services holding company and the parent of Merrill Lynch, provides
the Fund with investment advisory and administrative services. The Investment
Adviser acts as the investment adviser to more than 50 registered investment
companies and offers investment advisory services to individuals and
institutional accounts. As of June 30, 2005, the Investment Adviser and its
affiliates, including MLIM, had a total of approximately $474 billion in
investment company and other portfolio assets under management, including
approximately $221 billion in fixed income assets. This amount includes assets
managed by certain affiliates of the Investment Adviser. The Investment
Adviser is a limited partnership, the partners of which are ML & Co. and
Princeton Services. The principal business address of the Investment Adviser
is 800 Scudders Mill Road, Plainsboro, New Jersey 08536.

      The Investment Advisory Agreement provides that, subject to the
oversight of the Fund's Board of Directors, the Investment Adviser is
responsible for the actual management of the Fund's portfolio. The
responsibility for making decisions to buy, sell or hold a particular security
rests with the Investment Adviser, subject to oversight by the Board of
Directors.

      The portfolio manager primarily responsible for the Fund's day to day
management is Robert A. DiMella. Mr. DiMella has been a portfolio manager with
MLIM since 1997, was a Vice President of MLIM from 1997 to 2001, was a
Director (Tax-Exempt Fund Management) of MLIM from 2002 to 2004, has been a
Managing Director of MLIM sine 2004 and has 15 years of experience investing
in Municipal Bonds as a portfolio manager on behalf of registered investment
companies.. The Fund's portfolio manager will consider analyses from various
sources, make the necessary investment decisions, and place orders for
transactions accordingly.

      For its services, the Fund pays the Investment Adviser a monthly fee at
the annual rate of 0.50% of the Fund's average weekly net assets ("average
weekly net assets" means the average weekly value of the total assets of the
Fund, including the proceeds from the issuance of preferred stock, minus the
sum of (i) accrued liabilities of the Fund, (ii) any accrued and unpaid
interest on outstanding borrowings and (iii) accumulated dividends on shares
of preferred stock). For purposes of this calculation, average weekly net
assets is determined at the end of each month on the basis of the average net
assets of the Fund for each week during the month. The assets for each weekly
period are determined by averaging the net assets at the last business day of
a week with the net assets at the last business day of the prior week. The
liquidation preference of any outstanding preferred stock (other than
accumulated dividends) is not considered a liability in determining the Fund's
average weekly net assets.

      For the fiscal years ended April 30, 2005, 2004 and 2003, the fees paid
by the Fund to the Investment Adviser pursuant to the Investment Advisory
Agreement were $1,805,447, $1,795,371 and $1,732,165, respectively.

      For the fiscal years ended April 30, 2005, 2004 and 2003, the Investment
Adviser reimbursed the Fund $1,971, $5,817 and $2,403, respectively.

      The Investment Advisory Agreement obligates the Investment Adviser to
provide investment advisory services and to pay all compensation of and
furnish office space for officers and employees of the Fund connected with
investment and economic research, trading and investment management of the
Fund, as well as the compensation of all Directors of the Fund who are
affiliated persons of the Investment Adviser or any of its affiliates. The
Fund pays all other expenses incurred in the operation of the Fund, including,
among other things, expenses for legal and auditing services, taxes, costs of
preparing, printing and mailing proxies, listing fees, stock certificates and
stockholder reports, charges of the custodian and the transfer agent, dividend
disbursing agent and registrar, Commission fees, fees and expenses of
non-interested Directors, accounting and pricing costs, insurance, interest,
brokerage costs, litigation and other extraordinary or non-recurring expenses,
mailing and other expenses properly payable by the Fund. Certain accounting
services are provided to the Fund by State Street Bank and Trust Company
("State Street") pursuant to an agreement between State Street and the Fund.
The Fund will pay the costs of these services. In addition, the Fund will
reimburse the Investment Adviser for certain additional accounting services.

      The table below shows the amounts paid by the Fund to State Street and
to the Investment Adviser for accounting services for the years indicated:

Portfolio Manager Compensation

      Portfolio Manager Compensation

      The Portfolio Manager Compensation Program of MLIM and its affiliates,
including the Investment Adviser, is critical to MLIM's ability to attract and
retain the most talented asset management professionals. This program ensures
that compensation is aligned with maximizing investment returns and it
provides a competitive pay opportunity for competitive performance.

      Compensation Program

      The elements of total compensation for MLIM and its affiliates portfolio
managers are a fixed base salary, annual performance-based cash and stock
compensation (cash and stock bonus) and other benefits. MLIM has balanced
these components of pay to provide portfolio managers with a powerful
incentive to achieve consistently superior investment performance. By design,
portfolio manager compensation levels fluctuate -- both up and down -- with
the relative investment performance of the portfolios that they manage.



                                      29
<PAGE>

      Base Salary

      Under the MLIM approach, like that of many asset management firms, base
salaries represent a relatively small portion of a portfolio manager's total
compensation. This approach serves to enhance the motivational value of the
performance-based (and therefore variable) compensation elements of the
compensation program.

      Performance-Based Compensation

      MLIM believes that the best interests of investors are served by
recruiting and retaining exceptional asset management talent and managing
their compensation within a consistent and disciplined framework that
emphasizes pay for performance in the context of an intensely competitive
market for talent. To that end, MLIM and its affiliates portfolio manager
incentive compensation is based on a formulaic compensation program. MLIM's
formulaic portfolio manager compensation program includes: investment
performance relative to a subset of general closed-end, leveraged, municipal
debt funds over 1-, 3- and 5-year performance periods and a measure of
operational efficiency. If a portfolio manager's tenure is less than 5 years,
performance periods will reflect time in position. Portfolio managers are
compensated based on products they manage. A discretionary element of
portfolio manager compensation may include consideration of: financial
results, expense control, profit margins, strategic planning and
implementation, quality of client service, market share, corporate reputation,
capital allocation, compliance and risk control, leadership, workforce
diversity, supervision, technology and innovation. MLIM and its affiliates
also consider the extent to which individuals exemplify and foster ML & Co.'s
principles of client focus, respect for the individual, teamwork, responsible
citizenship and integrity. All factors are considered collectively by MLIM
management.

      Cash Bonus

      Performance-based compensation is distributed to portfolio managers in a
combination of cash and stock. Typically, the cash bonus, when combined with
base salary, represents more than 60% of total compensation for portfolio
managers.

      Stock Bonus

      A portion of the dollar value of the total annual performance-based
bonus is paid in restricted shares of ML & Co. stock. Paying a portion of
annual bonuses in stock puts compensation earned by a portfolio manager for a
given year "at risk" based on the company's ability to sustain and improve its
performance over future periods. The ultimate value of stock bonuses is
dependent on future ML & Co. stock price performance. As such, the stock bonus
aligns each portfolio manager's financial interests with those of the ML & Co.
shareholders and encourages a balance between short-term goals and long-term
strategic objectives. Management strongly believes that providing a
significant portion of competitive performance-based compensation in stock is
in the best interests of investors and shareholders. This approach ensures
that portfolio managers participate as shareholders in both the "downside
risk" and "upside opportunity" of the company's performance. Portfolio
managers therefore have a direct incentive to protect ML & Co.'s reputation
for integrity.

      Other Compensation Programs

      Portfolio managers who meet relative investment performance and
financial management objectives during a performance year are eligible to
participate in a deferred cash program. Awards under this program are in the
form of deferred cash that may be benchmarked to a menu of MLIM mutual funds
(including their own fund) during a five-year vesting period. The deferred
cash program aligns the interests of participating portfolio managers with the
investment results of MLIM products and promotes continuity of successful
portfolio management teams.

      Other Benefits

      Portfolio managers are also eligible to participate in broad-based plans
offered generally to employees of ML & Co. and its affiliates, including
broad-based retirement, 401(k), health, and other employee benefit plans.



                                      30
<PAGE>

Potential Material Conflicts of Interest

      Real, potential or apparent conflicts of interest may arise when a
portfolio manager has day-to-day portfolio management responsibilities with
respect to more than one fund or account, including the following:

      Certain investments may be appropriate for the Fund and also for other
clients advised by the Investment. Adviser and its affiliates, including other
client accounts managed by the Fund's portfolio management team. Investment
decisions for the Fund and other clients are made with a view to achieving
their respective investment objectives and after consideration of such factors
as their current holdings, availability of cash for investment and the size of
their investments generally. Frequently, a particular security may be bought
or sold for only one client or in different amounts and at different times for
more than one but less than all clients. Likewise, because clients of the
Investment Adviser and its affiliates may have differing investment
strategies, a particular security may be bought for one or more clients when
one or more other clients are selling the security. The investment results for
the Fund may differ from the results achieved by other clients of the
Investment Adviser and its affiliates and results among clients may differ. In
addition, purchases or sales of the same security may be made for two or more
clients on the same day. In such event, such transactions will be allocated
among the clients in a manner believed by the Investment Adviser and its
affiliates to be equitable to each. The Investment Adviser will not determine
allocations based on whether it receives a performance based fee from the
client. In some cases, the allocation procedure could have an adverse effect
on the price or amount of the securities purchased or sold by the Fund.
Purchase and sale orders for the Fund may be combined with those of other
clients of the Investment Adviser and its affiliates in the interest of
achieving the most favorable net results to the Fund.

      To the extent that the Fund's portfolio management team has
responsibilities for managing accounts in addition to the Fund, a portfolio
manager will need to divide his time and attention among relevant accounts.

      In some cases, a real, potential or apparent conflict may also arise
where (i) the Investment Adviser may have an incentive, such as a performance
based fee, in managing one account and not with respect to other accounts it
manages or (ii) where a member of the Fund's portfolio management team owns an
interest in one fund or account he or she manages and not another.



Code of Ethics

      The Fund's Board of Directors approved a Code of Ethics under Rule 17j-1
of the 1940 Act that covers the Fund and the Investment Adviser. The Code of
Ethics establishes procedures for personal investing and restricts certain
transactions. Employees subject to the Code of Ethics may invest in securities
for their personal investment accounts, including securities that may be
purchased or held by the Fund.

Proxy Voting Policies and Procedures

      The Fund's Board of Directors has delegated to the Investment Adviser
authority to vote all proxies relating to the Fund's portfolio securities. The
Investment Adviser has adopted policies and procedures ("Proxy Voting
Procedures") with respect to the voting of proxies related to the portfolio
securities held in the account of one or more of its clients, including the
Fund. Pursuant to these Proxy Voting Procedures, the Investment Adviser's
primary objective when voting proxies is to make proxy voting decisions solely
in the best interests of the Fund and its stockholders, and to act in a manner
that the Investment Adviser believes is most likely to enhance the economic
value of the securities held by the Fund. The Proxy Voting Procedures are
designed to ensure that the Investment Adviser considers the interests of its
clients, including the Fund, and not the interests of the Investment Adviser,
when voting proxies and that real (or perceived) material conflicts that may
arise between the Investment Adviser's interest and those of the Investment
Adviser's clients are properly addressed and resolved.

      In order to implement the Proxy Voting Procedures, the Investment
Adviser has formed a Proxy Voting Committee (the "Proxy Committee"). The Proxy
Committee is comprised of the Investment Adviser's Chief Investment Officer
(the "CIO"), one or more other senior investment professionals appointed by
the CIO, portfolio



                                      31
<PAGE>

managers and investment analysts appointed by the CIO and any other personnel
the CIO deems appropriate. The Proxy Committee will also include two
non-voting representatives from the Investment Adviser's Legal department
appointed by the Investment Adviser's General Counsel. The Proxy Committee's
membership shall be limited to full-time employees of the Investment Adviser.
No person with any investment banking, trading, retail brokerage or research
responsibilities for the Investment Adviser's affiliates may serve as a member
of the Proxy Committee or participate in its decision making (except to the
extent such person is asked by the Proxy Committee to present information to
the Proxy Committee, on the same basis as other interested knowledgeable
parties not affiliated with the Investment Adviser might be asked to do so).
The Proxy Committee determines how to vote the proxies of all clients,
including the Fund, that have delegated proxy voting authority to the
Investment Adviser and seeks to ensure that all votes are consistent with the
best interests of those clients and are free from unwarranted and
inappropriate influences. The Proxy Committee establishes general proxy voting
policies for the Investment Adviser and is responsible for determining how
those policies are applied to specific proxy votes, in light of each issuer's
unique structure, management, strategic options and, in certain circumstances,
probable economic and other anticipated consequences of alternate actions. In
so doing, the Proxy Committee may determine to vote a particular proxy in a
manner contrary to its generally stated policies. In addition, the Proxy
Committee will be responsible for ensuring that all reporting and
recordkeeping requirements related to proxy voting are fulfilled.

      The Proxy Committee may determine that the subject matter of a recurring
proxy issue is not suitable for general voting policies and requires a
case-by-case determination. In such cases, the Proxy Committee may elect not
to adopt a specific voting policy applicable to that issue. The Investment
Adviser believes that certain proxy voting issues require investment
analysis--such as approval of mergers and other significant corporate
transactions-- akin to investment decisions, and are, therefore, not suitable
for general guidelines. The Proxy Committee may elect to adopt a common
position for the Investment Adviser on certain proxy votes that are akin to
investment decisions, or determine to permit the portfolio manager to make
individual decisions on how best to maximize economic value for the Fund
(similar to normal buy/sell investment decisions made by such portfolio
managers). While it is expected that the Investment Adviser will generally
seek to vote proxies over which the Investment Adviser exercises voting
authority in a uniform manner for all the Investment Adviser's clients, the
Proxy Committee, in conjunction with the Fund's portfolio manager, may
determine that the Fund's specific circumstances require that its proxies be
voted differently.

      To assist the Investment Adviser in voting proxies, the Proxy Committee
has retained Institutional Shareholder Services ("ISS"). ISS is an independent
adviser that specializes in providing a variety of fiduciary-level proxy
related services to institutional investment managers, plan sponsors,
custodians, consultants, and other institutional investors. The services
provided to the Investment Adviser by ISS include in-depth research, voting
recommendations (although the Investment Adviser is not obligated to follow
such recommendations), vote execution, and recordkeeping. ISS will also assist
the Fund in fulfilling its reporting and recordkeeping obligations under the
1940 Act.

      The Investment Adviser's Proxy Voting Procedures also address special
circumstances that can arise in connection with proxy voting. For instance,
under the Proxy Voting Procedures, the Investment Adviser generally will not
seek to vote proxies related to portfolio securities that are on loan,
although it may do so under circumstances. In addition, the Investment Adviser
will vote proxies related to securities of foreign issuers only on a best
efforts basis and may elect not to vote at all in certain countries where the
Proxy Committee determines that the costs associated with voting generally
outweigh the benefits. The Proxy Committee may at any time override these
general policies if it determines that such action is in the best interests of
the Fund.

      From time to time, the Investment Adviser may be required to vote
proxies in respect of an issuer where an affiliate of the Investment Adviser
(each, an "Affiliate"), or a money management or other client of the
Investment Adviser, including investment companies for which the Investment
Adviser provides investment advisory, administrative and/or other services
(each, a "Client") is involved. The Proxy Voting Procedures and the Investment
Adviser's adherence to those procedures are designed to address such conflicts
of interest. The Proxy Committee intends to strictly adhere to the Proxy
Voting Procedures in all proxy matters, including matters involving Affiliates
and Clients. If, however, an issue representing a non-routine matter that is
material to an Affiliate or a widely known Client is involved such that the
Proxy Committee does not reasonably believe it is able to follow its
guidelines (or if the particular proxy matter is not addressed by the
guidelines) and vote impartially, the Proxy Committee may, in its discretion
for the purposes of ensuring that an independent determination is reached,
retain an



                                      32
<PAGE>

independent fiduciary to advise the Proxy Committee on how to vote or to cast
votes on behalf of the Investment Adviser's clients.

      In the event that the Proxy Committee determines not to retain an
independent fiduciary, or it does not follow the advice of such an independent
fiduciary, the Proxy Committee may pass the voting power to a subcommittee,
appointed by the CIO (with advice from the Secretary of the Proxy Committee),
consisting solely of Committee members selected by the CIO. The CIO shall
appoint to the subcommittee, where appropriate, only persons whose job
responsibilities do not include contact with the Client and whose job
evaluations would not be affected by the Investment Adviser's relationship
with the Client (or failure to retain such relationship). The subcommittee
shall determine whether and how to vote all proxies on behalf of the
Investment Adviser's clients or, if the proxy matter is, in their judgment,
akin to an investment decision, to defer to the applicable portfolio managers,
provided that, if the subcommittee determines to alter the Investment
Adviser's normal voting guidelines or, on matters where the Investment
Adviser's policy is case-by-case, does not follow the voting recommendation of
any proxy voting service or other independent fiduciary that may be retained
to provide research or advice to the Investment Adviser on that matter, no
proxies relating to the Client may be voted unless the Secretary, or in the
Secretary's absence, the Assistant Secretary of the Proxy Committee concurs
that the subcommittee's determination is consistent with the Investment
Adviser's fiduciary duties.

      In addition to the general principles outlined above, the Investment
Adviser has adopted voting guidelines with respect to certain recurring proxy
issues that are not expected to involve unusual circumstances. These policies
are guidelines only, and the Investment Adviser may elect to vote differently
from the recommendation set forth in a voting guideline if the Proxy Committee
determines that it is in the Fund's best interest to do so. In addition, the
guidelines may be reviewed at any time upon the request of a Committee member
and may be amended or deleted upon the vote of a majority of Committee members
present at a Committee meeting at which there is a quorum.

      The Investment Adviser has adopted specific voting guidelines with
respect to the following proxy issues:

      o   Proposals related to the composition of the board of directors of
          issuers other than investment companies. As a general matter, the
          Proxy Committee believes that a company's board of directors (rather
          than stockholders) is most likely to have access to important,
          nonpublic information regarding a company's business and prospects,
          and is therefore best-positioned to set corporate policy and oversee
          management. The Proxy Committee, therefore, believes that the
          foundation of good corporate governance is the election of
          qualified, independent corporate directors who are likely to
          diligently represent the interests of stockholders and oversee
          management of the corporation in a manner that will seek to maximize
          stockholder value over time. In individual cases, the Proxy
          Committee may look at a nominee's number of other directorships,
          history of representing stockholder interests as a director of other
          companies or other factors, to the extent the Proxy Committee deems
          relevant.

      o   Proposals related to the selection of an issuer's independent
          auditors. As a general matter, the Proxy Committee believes that
          corporate auditors have a responsibility to represent the interests
          of stockholders and provide an independent view on the propriety of
          financial reporting decisions of corporate management. While the
          Proxy Committee will generally defer to a corporation's choice of
          auditor, in individual cases, the Proxy Committee may look at an
          auditors' history of representing stockholder interests as auditor
          of other companies, to the extent the Proxy Committee deems
          relevant.

      o   Proposals related to management compensation and employee benefits.
          As a general matter, the Proxy Committee favors disclosure of an
          issuer's compensation and benefit policies and opposes excessive
          compensation, but believes that compensation matters are normally
          best determined by an issuer's board of directors, rather than
          stockholders. Proposals to "micro-manage" an issuer's compensation
          practices or to set arbitrary restrictions on compensation or
          benefits will, therefore, generally not be supported.

      o   Proposals related to requests, principally from management, for
          approval of amendments that would alter an issuer's capital
          structure. As a general matter, the Proxy Committee will support
          requests that



                                      33
<PAGE>

          enhance the rights of common stockholders and oppose requests that
          appear to be unreasonably dilutive.

      o   Proposals related to requests for approval of amendments to an
          issuer's charter or by-laws. As a general matter, the Proxy
          Committee opposes poison pill provisions.

      o   Routine proposals related to requests regarding the formalities of
          corporate meetings.

      o   Proposals related to proxy issues associated solely with holdings of
          investment company shares. As with other types of companies, the
          Proxy Committee believes that a fund's board of directors (rather
          than its stockholders) is best-positioned to set fund policy and
          oversee management. However, the Proxy Committee opposes granting
          boards of directors authority over certain matters, such as changes
          to a fund's investment objective, that the Investment Company Act
          envisions will be approved directly by stockholders.

      o   Proposals related to limiting corporate conduct in some manner that
          relates to the stockholder's environmental or social concerns. The
          Proxy Committee generally believes that annual stockholder meetings
          are inappropriate forums for discussion of larger social issues, and
          opposes stockholder resolutions "micro-managing" corporate conduct
          or requesting release of information that would not help a
          stockholder evaluate an investment in the corporation as an economic
          matter. While the Proxy Committee is generally supportive of
          proposals to require corporate disclosure of matters that seem
          relevant and material to the economic interests of stockholders, the
          Proxy Committee is generally not supportive of proposals to require
          disclosure of corporate matters for other purposes.

      Information about how the Fund voted proxies relating to securities held
by the Fund's portfolio during he most recent 12 month period ended June 30 is

and Exchange Commission's website at www.sec.gov.


                            PORTFOLIO TRANSACTIONS

      Subject to policies established by the Board of Directors, the
Investment Adviser is primarily responsible for the execution of the Fund's
portfolio transactions and the allocation of brokerage. The Fund has no
obligation to deal with any dealer or group of dealers in the execution of
transactions in portfolio securities of the Fund. Where possible, the Fund
deals directly with the dealers who make a market in the securities involved
except in those circumstances where better prices and execution are available
elsewhere. It is the policy of the Fund to obtain the best results in
conducting portfolio transactions for the Fund, taking into account such
factors as price (including the applicable dealer spread or commission), the
size, type and difficulty of the transaction involved, the firm's general
execution and operations facilities and the firm's risk in positioning the
securities involved. The cost of portfolio securities transactions of the Fund
primarily consists of dealer or underwriter spreads and brokerage commissions.
While reasonable competitive spreads or commissions are sought, the Fund will
not necessarily be paying the lowest spread or commission available on any
particular transaction.

      Subject to obtaining the best net results, dealers who provide
supplemental investment research (such as quantitative and modeling
information assessments and statistical data and provide other similar
services) to the Investment Adviser may receive orders for transactions by the
Fund. Information so received will be in addition to and not in lieu of the
services required to be performed by the Investment Adviser under the
Investment Advisory Agreement and the expense of the Investment Adviser will
not necessarily be reduced as a result of the receipt of such supplemental
information. Supplemental investment research obtained from such dealers might
be used by the Investment Adviser in servicing all of its accounts and such
research might not be used by the Investment Adviser in connection with the
Fund.

      The Fund invests in securities traded in the over-the-counter markets,
and the Fund intends to deal directly with dealers who make markets in the
securities involved, except in those circumstances where better execution is
available elsewhere. Under the 1940 Act, except as permitted by exemptive
order, persons affiliated with the Fund,



                                      34
<PAGE>

including Merrill Lynch, are prohibited from dealing with the Fund as
principal in the purchase and sale of securities. Since transactions in the
over-the-counter market usually involve transactions with dealers acting as
principals for their own accounts, the Fund does not deal with Merrill Lynch
and its affiliates in connection with such principal transactions except that,
pursuant to exemptive orders obtained by the Investment Adviser, the Fund may
engage in principal transactions with Merrill Lynch in high quality, short
term, tax exempt securities. See "Investment Restrictions." However,
affiliated persons of the Fund, including Merrill Lynch, may serve as its
brokers in certain over-the-counter transactions conducted on an agency basis.
In addition, the Fund has received an exemptive order, under which it may
purchase investment grade Municipal Bonds through group orders from an
underwriting syndicate of which Merrill Lynch is a member subject to
conditions set forth in such order (the "Group Order Exemptive Order"). A
group order is an order for securities held in an underwriting syndicate for
the account of all members of the syndicate, and in proportion to their
respective participation in the syndicate.

      The Fund also may purchase tax exempt debt instruments in individually
negotiated transactions with the issuers. Because an active trading market may
not exist for such securities, the prices that the Fund may pay for these
securities or receive on their resale may be lower than that for similar
securities with a more liquid market.

      Certain court decisions have raised questions as to the extent to which
investment companies should seek exemptions under the 1940 Act in order to
seek to recapture underwriting and dealer spreads from affiliated entities.
The Fund's Board of Directors has considered all factors deemed relevant and
has made a determination not to seek such recapture at this time. The Fund's
Board of Directors will reconsider this matter from time to time.

      For the fiscal year ended April 30, 2005, the Fund paid $1,500 in
brokerage commissions to Merrill Lynch. For the fiscal years ended April 30,
2004 and 2003, the Fund paid no brokerage commissions.

      Securities held by the Fund may also be held by, or be appropriate
investments for, other funds or investment advisory clients for which the
Investment Adviser or its affiliates act as an adviser. Because of different
investment objectives or other factors, a particular security may be bought
for an advisory client when other clients are selling the same security. If
purchases or sales of securities by the Investment Adviser for the Fund or
other funds for which it acts as investment adviser or for other advisory
clients arise for consideration at or about the same time, transactions in
such securities will be made, insofar as feasible, for the respective funds
and clients in a manner deemed equitable to all. Transactions effected by the
Investment Adviser (or its affiliates) on behalf of more than one of its
clients during the same period may increase the demand for securities being
purchased or the supply of securities being sold, causing an adverse effect on
price.

      Section 11(a) of the Securities Exchange Act of 1934 generally prohibits
members of the U.S. national securities exchanges from executing exchange
transactions for their affiliates and institutional accounts that they manage
unless the member (i) has obtained prior express authorization from the
account to effect such transactions, (ii) at least annually furnishes the
account with a statement setting forth the aggregate compensation received by
the member in effecting such transactions, and (iii) complies with any rules
the Commission has prescribed with respect to the requirements of clauses (i)
and (ii). To the extent Section 11(a) would apply to Merrill Lynch acting as a
broker for the Fund in any of its portfolio transactions executed on any such
securities exchange of which it is a member, appropriate consents have been
obtained from the Fund and annual statements as to aggregate compensation will
be provided to the Fund.

Portfolio Turnover

      Generally, the Fund does not purchase securities for short term trading
profits. However, the Fund may dispose of securities without regard to the
time they have been held when such actions, for defensive or other reasons,
appear advisable to the Investment Adviser. While it is not possible to
predict turnover rates with any certainty, at present it is anticipated that
the Fund's annual portfolio turnover rate, under normal circumstances, should
be less than 100%. (The portfolio turnover rate is calculated by dividing the
lesser of purchases or sales of portfolio securities for the particular fiscal
year by the monthly average of the value of the portfolio securities owned by
the Fund during the particular fiscal year. For purposes of determining this
rate, all securities whose maturities at the time of acquisition are one year
or less are excluded.) A high portfolio turnover rate results in greater
transaction costs, which are borne directly by the Fund and may have certain
tax consequences for stockholders.



                                      35
<PAGE>

      For the fiscal years ended April 30, 2005. 2004 and 2003, the Fund's
portfolio turnover rates were 51.81%, 39.94% and 49.59%, respectively.

                                     TAXES

      The Fund has elected to qualify for the special tax treatment afforded
regulated investment companies ("RICs") under the Internal Revenue Code of
1986, as amended (the "Code"). As long as it so qualifies, in any taxable year
in which it distributes at least 90% of its taxable net income and 90% of its
tax exempt net income (see below), the Fund (but not its stockholders) will
not be subject to Federal income tax to the extent that it distributes its net
investment income and net realized capital gains. The Fund intends to
distribute substantially all of such income. If, in any taxable year, the Fund
fails to qualify as a RIC under the Code, it would be taxed in the same manner
as an ordinary corporation and all distributions from earnings and profits (as
determined under U.S. Federal income tax principles) to its stockholders would
be taxable as ordinary dividend income eligible for the maximum 15% tax rate
for non-corporate shareholders and the dividends-received deduction for
corporate shareholders. However, the Fund's distributions derived from income
on tax exempt obligations, as defined herein, would no longer qualify for
treatment as exempt interest.

      The Code requires a RIC to pay a nondeductible 4% excise tax to the
extent the RIC does not distribute, during each calendar year, 98% of its
ordinary income, determined on a calendar year basis, and 98% of its capital
gains, determined, in general, on an April 30 year-end, plus certain
undistributed amounts from previous years. The required distributions,
however, are based only on the taxable income of a RIC. The excise tax,
therefore, generally will not apply to the tax exempt income of a RIC, such as
the Fund, that pays exempt-interest dividends.

      The Internal Revenue Service (the "IRS"), in a revenue ruling, held that
certain auction rate preferred stock would be treated as stock for Federal
income tax purposes. The terms of the AMPS are substantially similar, but not
identical, to the auction rate preferred stock discussed in the revenue
ruling, and in the opinion of Sidley Austin Brown & Wood LLP, counsel to the
Fund, the shares of AMPS will constitute stock of the Fund and distributions
with respect to shares of AMPS (other than distributions in redemption of
shares of AMPS subject to Section 302(b) of the Code) will constitute
dividends to the extent of the Fund's current and accumulated earnings and
profits as calculated for Federal income tax purposes. Nevertheless, it is
possible that the IRS might take a contrary position, asserting, for example,
that the shares of AMPS constitute debt of the Fund. If this position were
upheld, the discussion of the treatment of distributions below would not
apply. Instead, distributions by the Fund to holders of shares of AMPS would
constitute taxable interest income, whether or not they exceeded the earnings
and profits of the Fund, would be included in full in the income of the
recipient and would be taxed as ordinary income. Counsel believes that such a
position, if asserted by the IRS, would be unlikely to prevail.

      The Fund will only purchase a Municipal Bond or Non-Municipal Tax-Exempt
Security if it is accompanied by an opinion of counsel to the issuer, which is
delivered on the date of issuance of the security, that the interest paid on
such security is excludable from gross income for Federal income tax purposes
(i.e., "tax-exempt"). The Fund intends to qualify to pay "exempt-interest
dividends" as defined in Section 852(b)(5) of the Code. Under such section if,
at the close of each quarter of its taxable year, at least 50% of the value of
its total assets consists of obligations that pay interest which is excludable
from gross income for Federal income tax purposes ("tax exempt obligations")
under Section 103(a) of the Code (relating generally to obligations of a state
or local governmental unit), the Fund shall be qualified to pay
exempt-interest dividends to its stockholders. Exempt-interest dividends are
dividends or any part thereof paid by the Fund that are attributable to
interest on tax exempt obligations and designated by the Fund as
exempt-interest dividends in a written notice mailed to the Fund's
stockholders within 60 days after the close of its taxable year. To the extent
that the dividends distributed to the Fund's stockholders are derived from
interest income exempt from tax under Code Section 103(a) and are properly
designated as exempt-interest dividends, they will be excludable from a
stockholder's gross income for Federal tax purposes. Exempt-interest dividends
are included, however, in determining the portion, if any, of a person's
social security and railroad retirement benefits subject to Federal income
taxes. Each stockholder is advised to consult a tax adviser with respect to
whether exempt-interest dividends retain the exclusion under Code Section
103(a) if such stockholder would be treated as a "substantial user" or
"related person" under Code Section 147(a) with respect to property financed
with the proceeds of an issue of PABs, if any, held by the Fund.



                                      36
<PAGE>

      To the extent that the Fund's distributions are derived from interest on
its taxable investments or from an excess of net short-term capital gains over
net long-term capital losses ("ordinary income dividends"), such distributions
generally are considered ordinary income for Federal income tax purposes.
Distributions by the Fund, whether from exempt-interest income, ordinary
income or capital gains, are not eligible for the dividends received deduction
allowed to corporations under the Code or the reduced tax rates available to
non-corporate shareholders. Distributions, if any, from an excess of net
long-term capital gains over net short-term capital losses derived from the
sale of securities or from certain transactions in futures, or options and
swaps ("capital gain dividends") are taxable as long-term capital gains for
Federal income tax purposes, regardless of the length of time the stockholder
has owned Fund shares. Generally not later than 60 days after the close of its
taxable year, the Fund will provide its stockholders with a written notice
designating the amounts of any exempt-interest dividends and capital gain
dividends. If the Fund pays a dividend in January which was declared in the
previous October, November or December to stockholders of record on a
specified date in one of such months, then such dividend will be treated for
tax purposes as being paid by the Fund and received by its stockholders on
December 31 of the year in which such dividend was declared.

      All or a portion of the Fund's gain from the sale or redemption of tax
exempt obligations purchased at a market discount will be treated for Federal
income tax purposes as ordinary income rather than capital gain. This rule may
increase the amount of ordinary income dividends received by stockholders.
Distributions in excess of the Fund's earnings and profits will first reduce
the adjusted tax basis of a holder's shares and, after such adjusted tax basis
is reduced to zero, will constitute capital gains to such holder (assuming the
shares are held as a capital asset). The sale or exchange of AMPS could result
in capital gain or loss to holders of AMPS who hold their shares as capital
assets. Generally, a stockholder's gain or loss will be long-term capital gain
or loss if the shares have been held for more than one year. Any loss upon the
sale or exchange of Fund shares held for six months or less will be disallowed
to the extent of any exempt-interest dividends received by the stockholder. In
addition, any such loss that is not disallowed under the rule stated above
will be treated as long-term capital loss to the extent of any capital gain
dividends received by the stockholder.

      If you borrow money to buy the Fund's AMPS, you may not be permitted to
deduct the interest on that loan. Under Federal income tax rules, the Fund's
AMPS may be treated as having been bought with borrowed money even if the
purchase cannot be traced directly to borrowed money. Stockholders should
consult their own tax advisers regarding the impact of an investment in AMPS
upon the deductibility of interest payable by the stockholder.

      The IRS has taken the position in a revenue ruling that if a RIC has two
or more classes of shares, it may designate distributions made to each class
in any year as consisting of no more than such class's proportionate share of
particular types of income, including exempt-interest income and net long-term
capital gains. A class's proportionate share of a particular type of income is
determined according to the percentage of total dividends paid by the RIC
during such year that was paid to such class. Thus, the Fund is required to
allocate a portion of its net capital gain and other taxable income to the
shares of AMPS and Other AMPS of each series. Accordingly, the Fund intends to
designate dividends paid to the Series C AMPS and Other AMPS as tax exempt
interest, capital gains or other taxable income, as applicable, in proportion
to each series' share of total dividends paid during the year. The Fund may
notify the Auction Agent of the amount of any net capital gain and other
taxable income to be included in any dividend on shares of AMPS prior to the
Auction establishing the Applicable Rate for such dividend. The Fund also may
include such income in a dividend on shares of AMPS without giving advance
notice thereof if it increases the dividend by an additional amount calculated
as if such income were a Retroactive Taxable Allocation and the additional
amount were an Additional Dividend, provided that the Fund will notify the
Auction Agent of the additional amounts to be included in such dividend prior
to the applicable Dividend Payment Date. See "The Auction--Auction
Procedures--Auction Date; Advance Notice of Allocation of Taxable Income;
Inclusion of Taxable Income in Dividends" in the prospectus. Except for the
portion of any dividend that it informs the Auction Agent will be treated as
capital gains or other taxable income, the Fund anticipates that the dividends
paid on the shares of AMPS will constitute exempt-interest dividends. The
amount of net capital gain and ordinary income allocable to shares of AMPS
(the "taxable distribution") will depend upon the amount of such gains and
income realized by the Fund and the total dividends paid by the Fund on shares
of common stock and shares of the series of AMPS during a taxable year, but
the taxable distribution generally is not expected to be significant.



                                      37
<PAGE>

      If the Fund makes a Retroactive Taxable Allocation, it will pay
Additional Dividends to holders of AMPS who are subject to the Retroactive
Taxable Allocation. See "Description of AMPS--Dividends-- Additional
Dividends" in the prospectus. The Federal income tax consequences of
Additional Dividends under existing law are uncertain. The Fund intends to
treat a holder as receiving a dividend distribution in the amount of any
Additional Dividend only as and when such Additional Dividend is paid. An
Additional Dividend generally will be designated by the Fund as an
exempt-interest dividend except as otherwise required by applicable law.
However, the IRS may assert that all or part of an Additional Dividend is a
taxable dividend either in the taxable year for which the Retroactive Taxable
Allocation is made or in the taxable year in which the Additional Dividend is
paid.

      In the opinion of Sidley Austin Brown & Wood LLP, counsel to the Fund,
under current law the manner in which the Fund intends to allocate items of
tax exempt income, net capital gain and other taxable income among shares of
common stock and shares of AMPS will be respected for Federal income tax
purposes. However, the tax treatment of Additional Dividends may affect the
Fund's calculation of each class's allocable share of capital gains and other
taxable income. In addition, there is currently no direct guidance from the
IRS or other sources specifically addressing whether the Fund's method for
allocating tax exempt income, net capital gain and other taxable income, if
any, among shares of common stock and shares of the AMPS will be respected for
Federal income tax purposes, and it is possible that the IRS could disagree
with counsel's opinion and attempt to reallocate the Fund's net capital gain
or other taxable income. In the event of a reallocation, some of the dividends
identified by the Fund as exempt-interest dividends to holders of shares of
AMPS may be recharacterized as additional capital gains or other taxable
income. In the event of such recharacterization, the Fund would not be
required to make payments to such stockholders to offset the tax effect of
such reallocation. In addition, a reallocation may cause the Fund to be liable
for income tax and excise tax on any reallocated taxable income. Sidley Austin
Brown & Wood LLP has advised the Fund that, in its opinion, if the IRS were to
challenge in court the Fund's allocations of income and gain, the IRS would be
unlikely to prevail. A holder should be aware, however, that the opinion of
Sidley Austin Brown & Wood LLP represents only its best legal judgment and is
not binding on the IRS or the courts.

      The Code subjects interest received on certain otherwise tax exempt
securities to a Federal alternative minimum tax. The Federal alternative
minimum tax applies to interest received on PABs issued after August 7, 1986.
PABs are bonds that, although tax exempt, are used for purposes other than
those performed by governmental units and that benefit non-governmental
entities (e.g., bonds used for industrial development or housing purposes).
Income received on such bonds is classified as an item of "tax preference,"
which could subject certain investors in such bonds, including stockholders of
the Fund, to an increased Federal alternative minimum tax. The Fund intends to
purchase such PABs and will report to stockholders at the close of the
calendar year-end the portion of its dividends declared during the year which
constitutes an item of tax preference for Federal alternative minimum tax
purposes. The Code further provides that corporations are subject to a Federal
alternative minimum tax based, in part, on certain differences between taxable
income as adjusted for other tax preferences and the corporation's "adjusted
current earnings," which more closely reflect a corporation's economic income.
Because an exempt-interest dividend paid by the Fund will be included in
adjusted current earnings, a corporate stockholder may be required to pay a
Federal alternative minimum tax on exempt-interest dividends paid by the Fund.

      The Fund may invest in instruments the return on which includes
nontraditional features such as indexed principal or interest payments
("nontraditional instruments"). These instruments may be subject to special
tax rules under which the Fund may be required to accrue and distribute income
before amounts due under the obligations are paid. In addition, it is possible
that all or a portion of the interest payments on such nontraditional
instruments could be recharacterized as taxable ordinary income.

      The Fund may engage in interest rate and credit default swaps. The
Federal income tax rules governing the taxation of swaps are not entirely
clear and may require the Fund to treat payments received under such
arrangements as ordinary income and to amortize payments under certain
circumstances. Because payments received by the Fund in connection with swap
transactions will be taxable rather than tax exempt, they may result in
increased taxable distributions to stockholders.

      Certain transactions entered into by the Fund are subject to complex
Federal income tax provisions that may, among other things, (a) affect the
character of gains and losses realized, (b) disallow, suspend or otherwise
limit the allowance of certain losses or deductions, and (c) accelerate the
recognition of income. Operation of these tax rules could, therefore, affect
the character, amount and timing of distributions and result in increased
taxable



                                      38
<PAGE>

distributions to stockholders. Special tax rules also will require the Fund to
mark-to-market certain types of positions in its portfolio (i.e., treat them
as sold on the last day of the taxable year), and may result in the
recognition of income without a corresponding receipt of cash. The Fund
intends to monitor its transactions, make appropriate tax elections and make
appropriate entries in its books and records to lessen the effect of these tax
rules and avoid any possible disqualification for the special treatment
afforded RICs under the Code.

      The Fund's ability to distribute dividends exempt from Federal income
tax depends on the exclusion from gross income of the interest income that it
receives on the securities in which it invests. The Fund will only purchase
Municipal Bonds and Non-Municipal Tax-Exempt Securities if they are
accompanied by an opinion of counsel to the issuer, which is delivered on the
date of issuance of that security, that interest on such securities is
excludable from gross income for Federal income tax purposes (the "tax
exemption opinion").

      Events occurring after the date of issuance of the Municipal Bonds and
Non-Municipal Tax Exempt Securities in which the Fund invests, however, may
cause the interest on such securities to be includable in gross income for
Federal income tax purposes. For example, the Code establishes certain
requirements, such as restrictions as to the investment of the proceeds of the
issue, limitations as to the use of proceeds of such issue and the property
financed by such proceeds, and the payment of certain excess earnings to the
Federal government, that must be met after the issuance of securities for
interest on such securities to remain excludable from gross income for Federal
income tax purposes. The issuers and the conduit borrowers of the Municipal
Bonds or Non-Municipal Tax Exempt Securities generally covenant to comply with
such requirements, and the tax exemption opinion generally assumes continuing
compliance with such requirements. Failure to comply with these continuing
requirements, however, may cause the interest on such securities to be
includable in gross income for Federal income tax purposes retroactive to
their date of issue.

      In addition, the IRS has an ongoing enforcement program that involves
the audit of tax exempt bonds to determine whether an issue of bonds satisfies
all of the requirements that must be met for interest on such bonds to be
excludable from gross income for Federal income tax purposes. From time to
time, some of the securities held by the Fund may be the subject of such an
audit by the IRS, and the IRS may determine that the interest on such
securities is includable in gross income for Federal income tax purposes,
either because the IRS has taken a legal position adverse to the conclusion
reached by counsel to the issuer in the tax exemption opinion or as a result
of an action taken or not taken after the date of issue of such obligation. If
a Municipal Bond or Non- Municipal Tax Exempt Security in which the Fund
invests is determined to pay taxable interest subsequent to the Fund's
acquisition of such security, the IRS may demand that the Fund pay taxes on
the affected interest income. If the Fund agrees to do so, the Fund's yield on
its common stock could be adversely affected. A determination that interest on
a security held by the Fund is includable in gross income for Federal income
tax purposes retroactively to its date of issue may, likewise, cause a portion
of prior distributions received by stockholders, including holders of AMPS, to
be taxable to those stockholders in the year of receipt. The Fund will not pay
an Additional Dividend to a holder of AMPS under these circumstances.

      If at any time when shares of AMPS are outstanding the Fund does not
meet the asset coverage requirements of the 1940 Act, the Fund will be
required to suspend distributions to holders of common stock until the asset
coverage is restored. See "Description of AMPS--Dividends--Restrictions on
Dividends and Other Payments" and in the prospectus. This may prevent the Fund
from distributing at least 90% of its net income, and may, therefore,
jeopardize the Fund's qualification for taxation as a RIC. If the Fund were to
fail to qualify as a RIC, some or all of the distributions paid by the Fund
would be fully taxable for Federal income tax purposes. Upon any failure to
meet the asset coverage requirements of the 1940 Act, the Fund, in its sole
discretion, may, and under certain circumstances will be required to, redeem
shares of AMPS in order to maintain or restore the requisite asset coverage
and avoid the adverse consequences to the Fund and its stockholders of failing
to qualify as a RIC. See "Description of AMPS--Redemption" herein and in the
prospectus. There can be no assurance, however, that any such action would
achieve such objectives.

      As noted above, the Fund must distribute annually at least 90% of its
net taxable and tax exempt interest income. A distribution will only be
counted for this purpose if it qualifies for the dividends paid deduction
under the Code. Additional preferred stock that the Fund has authority to
issue may raise an issue as to whether distributions on such preferred stock
are "preferential" under the Code and therefore not eligible for the dividends
paid deduction. The Fund intends to issue preferred stock that counsel advises
will not result in the payment of a preferential



                                      39
<PAGE>

dividend. If the Fund ultimately relies on a legal opinion with regard to such
preferred stock, there is no assurance that the IRS would agree that dividends
on the preferred stock are not preferential. If the IRS successfully
disallowed the dividends paid deduction for dividends on the preferred stock,
the Fund could lose the benefit of the special treatment afforded RICs under
the Code. In this case, dividends paid by the Fund would not be exempt from
Federal income taxes. Additionally, the Fund would be subject to Federal
income tax, including the alternative minimum tax.

      Under certain Code provisions, some stockholders may be subject to a
withholding tax on ordinary income dividends, capital gain dividends and
redemption payments ("backup withholding"). Backup withholding may also be
required on distributions paid by the Fund, unless it reasonably estimates
that at least 95% of its distributions during the taxable year are comprised
of exempt-interest dividends. Generally, stockholders subject to backup
withholding will be those for whom no certified taxpayer identification number
is on file with the Fund or who, to the Fund's knowledge, have furnished an
incorrect number. When establishing an account, an investor must certify under
penalty of perjury that such number is correct and that such investor is not
otherwise subject to backup withholding. Backup withholding is not an
additional tax. Any amount withheld generally may be allowed as a refund or a
credit against a stockholder's Federal income tax liability, provided that the
required information is timely forwarded to the IRS.

      The Fund is generally not an appropriate investment for retirement
plans, other entities that are not subject to tax and foreign stockholders.

State and Local Taxes

      The exemption from Federal income tax for exempt-interest dividends does
not necessarily result in an exemption for such dividends under the income or
other tax laws of any state or local taxing authority. Stockholders are
advised to consult their own tax advisers concerning state and local matters.

      In some states, the portion of any exempt-interest dividend that is
derived from interest received by a RIC on its holdings of that state's
securities and its political subdivisions and instrumentalities is exempt from
that state's income tax. Therefore, the Fund will report annually to its
stockholders the percentage of interest income earned by the Fund during the
preceding year on tax exempt obligations indicating, on a state-by-state
basis, the source of such income.

      The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations presently in effect. For the
complete provisions, reference should be made to the pertinent Code sections
and the Treasury Regulations promulgated thereunder. The Code and the Treasury
Regulations are subject to change by legislative, judicial or administrative
action either prospectively or retroactively.

      Stockholders are urged to consult their tax advisers regarding specific
questions as to Federal, state, local or foreign taxes.

                             CONFLICTS OF INTEREST

      The investment activities of the Investment Adviser, Merrill Lynch and
other affiliates of Merrill Lynch for their own accounts and other accounts
they manage may give rise to conflicts of interest that could disadvantage the
Fund and its stockholders. The Investment Adviser has adopted written policies
and procedures that, collectively, address investment activities of, and other
arrangements involving, the Investment Adviser that may give rise to such
conflicts of interest.

      Merrill Lynch, as a diversified global financial services firm, is
involved with a broad spectrum of financial services and asset management
activities. Certain of Merrill Lynch's affiliates that are not service
providers to the Fund engage in a broad range of activities over which the
Investment Adviser has no control or ability to exercise oversight. Although
there are no formal written policies and procedures that cover all potential
or actual conflicts of interest, Merrill Lynch has established a number of
committees and related policies and procedures that are designed to identify,
analyze and/or resolve such conflicts of interest. No assurance can be given
that Merrill Lynch will be



                                      40
<PAGE>

able to identify each conflict of interest or that each identified conflict of
interest will be resolved in favor of the Fund.

      Merrill Lynch and its affiliates, including, without limitation, the
Investment Adviser and its advisory affiliates may have proprietary interests
in, and may manage or advise with respect to, accounts or funds (including
separate accounts and other funds and collective investment vehicles) that
have investment objectives similar to those of the Fund and/or that engage in
transactions in the same types of securities and instruments as the Fund.
Merrill Lynch and its affiliates are also major participants in, among others,
the options, swaps, and equities markets, in each case both on a proprietary
basis and for the accounts of customers. As such, Merrill Lynch and its
affiliates are actively engaged in transactions in the same securities and
instruments in which the Fund invests. Such activities could affect the prices
and availability of the securities and instruments in which the Fund invests,
which could have an adverse impact on the Fund's performance. Such
transactions, particularly in respect of most proprietary accounts or customer
accounts, will be executed independently of the Fund's transactions and thus
at prices or rates that may be more or less favorable than those obtained by
the Fund.

      The results of the Fund's investment activities may differ significantly
from the results achieved by the Investment Adviser and its affiliates for its
proprietary accounts or other accounts (including investment companies or
collective investment vehicles) managed or advised by the Investment Adviser.
It is possible that the Investment Adviser and its affiliates and such other
accounts will achieve investment results that are substantially more or less
favorable than the results achieved by the Fund. Moreover, it is possible that
the Fund will sustain losses during periods in which the Investment Adviser
and its affiliates achieve significant profits on their trading for
proprietary or other accounts. The opposite result is also possible.

      From time to time, the Fund's activities may also be restricted because
of regulatory restrictions applicable to Merrill Lynch and its affiliates,
and/or their internal policies designed to comply with such restrictions. As a
result, there may be periods, for example, when the Investment Adviser, and/or
its affiliates, will not initiate or recommend certain types of transactions
in certain securities or instruments with respect to which the Investment
Adviser and/or its affiliates are performing services or when position limits
have been reached.

      In connection with its management of the Fund, the Investment Adviser
may have access to certain fundamental analysis and proprietary technical
models developed by Merrill Lynch. The Investment Adviser will not be under
any obligation, however, to effect transactions on behalf of the Fund in
accordance with such analysis and models. In addition, neither Merrill Lynch
nor any of its affiliates will have any obligation to make available any
information regarding their proprietary activities or strategies, or the
activities or strategies used for other accounts managed by them, for the
benefit of the management of the Fund and it is not anticipated that the
Investment Adviser will have access to such information for the purpose of
managing the Fund. The proprietary activities or portfolio strategies of
Merrill Lynch and its affiliates or the activities or strategies used for
accounts managed by them or other customer accounts could conflict with the
transactions and strategies employed by the Investment Adviser in managing the
Fund.

      In addition, certain principals and certain employees of the Investment
Adviser are also principals or employees of Merrill Lynch or its affiliated
entities. As a result, the performance by these principals and employees of
their obligations to such other entities may be a consideration of which
investors in the Fund should be aware.

      The Investment Adviser may enter into transactions and invest in
securities and instruments on behalf of the Fund in which customers of Merrill
Lynch (or, to the extent permitted by the SEC, Merrill Lynch) serve as the
counterparty, principal or issuer. In such cases, such party's interests in
the transaction will be adverse to the interests of the Fund, and such party
may have no incentive to assure that the Fund obtains the best possible prices
or terms in connection with the transactions. In addition, the purchase,
holding and sale of such investments by the Fund may enhance the profitability
of Merrill Lynch. Merrill Lynch and its affiliates may also create, write or
issue derivative instruments for customers of Merrill Lynch or its affiliates,
the underlying securities or instruments of which may be those in which the
Fund invests or which may be based on the performance of the Fund. The Fund
may, subject to applicable law, purchase investments that are the subject of
an underwriting or other distribution by Merrill Lynch or its affiliates and
may also enter into transactions with other clients of Merrill Lynch or its
affiliates where such other clients have interests adverse to those of the
Fund. At times, these activities may cause departments of Merrill Lynch or its
affiliates to give advice to clients that may cause these clients to take
actions



                                      41
<PAGE>

adverse to the interests of the Fund. To the extent affiliated transactions
are permitted, the Fund will deal with Merrill Lynch and its affiliates on an
arms-length basis.

      The Fund will be required to establish business relationships with its
counterparties based on the Fund's own credit standing. Neither Merrill Lynch
nor its affiliates will have any obligation to allow their credit to be used
in connection with the Fund's establishment of its business relationships, nor
is it expected that the Fund's counterparties will rely on the credit of
Merrill Lynch or any of its affiliates in evaluating the Fund's
creditworthiness.

      It is also possible that, from time to time, Merrill Lynch or any of its
affiliates, may, although they are not required to, purchase, hold or sell
shares of the Fund.

      It is possible that the Fund may invest in securities of companies with
which Merrill Lynch has or is trying to develop investment banking
relationships as well as securities of entities in which Merrill Lynch makes a
market. The Fund also may invest in securities of companies that Merrill Lynch
provides or may someday provide research coverage. Such investments could
cause conflicts between the interests of the Fund and the interests of other
Merrill Lynch clients. In providing services to the Fund, the Investment
Adviser is not permitted to obtain or use material non-public information
acquired by any division, department or affiliate of Merrill Lynch in the
course of these activities. In addition, from time to time, Merrill Lynch's
activities may limit the Fund's flexibility in purchases and sales of
securities. When Merrill Lynch is engaged in an underwriting or other
distribution of securities of an entity, the Investment Adviser may be
prohibited from purchasing or recommending the purchase of certain securities
of that entity for the Fund.

      The Investment Adviser, its affiliates, and its directors, officers and
employees, may buy and sell securities or other investments for their own
accounts, and may have conflicts of interest with respect to investments made
on behalf of the Fund. As a result of differing trading and investment
strategies or constraints, positions may be taken by directors, officers and
employees and affiliates of the Investment Adviser that are the same,
different from or made at different times than positions taken for the Fund.
To lessen the possibility that the Fund will be adversely affected by this
personal trading, each of the Fund and the Investment Adviser has adopted a
Code of Ethics in compliance with Section 17(j) of the 1940 Act that restricts
securities trading in the personal accounts of investment professionals and
others who normally come into possession of information regarding the Fund's
portfolio transactions.

      The Investment Adviser and its affiliates will not purchase securities
or other property from, or sell securities or other property to, the Fund,
except that the Fund may, in accordance with rules adopted under the 1940 Act,
engage in transactions with accounts that are affiliated with the Fund as a
result of common officers, directors, or investment advisers. These
transactions would be effected in circumstances in which the Investment
Adviser determined that it would be appropriate for the Fund to purchase and
another client to sell, or the Fund to sell and another client to purchase,
the same security or instrument on the same day.

      Present and future activities of Merrill Lynch and its affiliates,
including of the Investment Adviser, in addition to those described in this
section, may give rise to additional conflicts of interest.



                                NET ASSET VALUE

      Net asset value per share of common stock is determined Monday through
Friday as of the close of business on the NYSE (generally, the NYSE closes at
4:00 p.m., Eastern time), on each business day during which the NYSE is open
for trading. For purposes of determining the net asset value of a share of
common stock, the value of the securities held by the Fund plus any cash or
other assets (including interest accrued but not yet received) minus all
liabilities (including accrued expenses) and the aggregate liquidation value
of any outstanding shares of preferred stock is divided by the total number of
shares of common stock outstanding at such time. Expenses, including the fees
payable to the Investment Adviser, are accrued daily.



                                      42
<PAGE>

      The Municipal Bonds and other portfolio securities in which the Fund
invests are traded primarily in over-the-counter ("OTC") municipal bond and
money markets and are valued at the last available bid price for long
positions and at the last available ask price for short positions in the OTC
market or on the basis of yield equivalents as obtained from one or more
dealers or pricing services approved by the Directors. One bond is the "yield
equivalent" of another bond when, taking into account market price, maturity,
coupon rate, credit rating and ultimate return of principal, both bonds will
theoretically produce an equivalent return to the bondholder. Financial
futures contracts and options thereon, which are traded on exchanges, are
valued at their settlement prices as of the close of such exchanges.
Short-term investments with a remaining maturity of 60 days or less are valued
on an amortized cost basis, which approximates market value, unless the
Investment Adviser believes that this method no longer produces fair
valuations. Repurchase agreements will be valued at cost plus accrued
interest. The value of swaps, including interest rate swaps, caps and floors,
will be determined by obtaining dealer quotations. Repurchase agreements will
be valued at cost plus accrued interest. Securities and assets for which
market quotations are not readily available are valued at fair value as
determined in good faith by or under the direction of the Directors, including
valuations furnished by a pricing service retained by the Fund, which may use
a matrix system for valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the general
supervision of the Directors.

      The Fund makes available for publication the net asset value of its
shares of common stock determined as of the last business day each week.
Currently, the net asset values of shares of publicly traded closed-end
investment companies investing in debt securities are published in Barron's,
the Monday edition of The Wall Street Journal and the Monday and Saturday
editions of The New York Times.

                             FINANCIAL STATEMENTS

      The Fund's audited financial statements for the fiscal year ended April
30, 2005, together with the report of ____________________ thereon, are
incorporated in this statement of additional information by reference to its
2004 Annual Report. You may request a copy of the 2004 Annual Report at no

                                  APPENDIX A

                     DESCRIPTION OF MUNICIPAL BOND RATINGS

Description of Moody's Municipal Bond Ratings

Aaa      Issuers or issues rated Aaa demonstrate the strongest
         creditworthiness relative to other US municipal or tax-exempt issuers
         or issues.

Aa       Issuers or issues rated Aa demonstrate very strong creditworthiness
         relative to other US municipal or tax-exempt issuers or issues.

A        Issuers or issues rated A present above-average creditworthiness
         relative to other US municipal or tax-exempt issuers or issues.

Baa      Issuers or issues rated Baa represent average creditworthiness
         relative to other US municipal or tax- exempt issuers or issues.

Ba       Issuers or issues rated Ba demonstrate below-average creditworthiness
         relative to other US municipal or tax-exempt issuers or issues.

B        Issuers or issues rated B demonstrate weak creditworthiness relative
         to other US municipal or tax- exempt issuers or issues.

Caa      Issuers or issues rated Caa demonstrate very weak creditworthiness
         relative to other US municipal or tax-exempt issuers or issues.

Ca       Issuers or issues rated Ca demonstrate extremely weak
         creditworthiness relative to other US municipal or tax-exempt issuers
         or issues.

C        Issuers or issues rated C demonstrate the weakest creditworthiness
         relative to other US municipal or tax-exempt issuers or issues.

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.

Description of Moody's Municipal Short-Term Debt Ratings

MIG1     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.

MIG2     This designation denotes strong credit quality. Margins of
         protection are ample, although not as large as in the preceding
         group.

MIG3     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.



                                     A-1
<PAGE>

Description of Moody's U.S. Municipal Demand Obligation Ratings

      In the case of variable rate demand obligations (VRDOs), a two-component
rating is assigned; a long or short-term debt rating and a demand obligation
rating. The first element represents Moody's evaluation of the degree of risk
associated with scheduled principal and interest payments. The second element
represents Moody's evaluation of the degree of risk associated with the
ability to receive purchase price upon demand ("demand feature"), using a
variation of the MIG rating scale, the Variable Municipal Investment Grade or
VMIG rating.

      When either the long- or short-term aspect of a VRDO is not rated, that
piece is designated NR, e.g., Aaa/NR or NR/VMIG 1.

      VMIG rating expirations are a function of each issue's specific
structural or credit features.

VMIG1    This designation denotes superior credit quality. Excellent
         protection is afforded by the superior short-term credit strength of
         the liquidity provider and structural and legal protections that
         ensure the timely payment of purchase price upon demand.

VMIG2    This designation denotes strong credit quality. Good protection is
         afforded by the strong short-term credit strength of the liquidity
         provider and structural and legal protections that ensure the timely
         payment of purchase price upon demand.

VMIG3    This designation denotes acceptable credit quality. Adequate
         protection is afforded by the satisfactory short-term credit strength
         of the liquidity provider and structural and legal protections that
         ensure the timely payment of purchase price upon demand.

SG       This designation denotes speculative-grade credit quality. Demand
         features rated in this category may be supported by a liquidity
         provider that does not have an investment grade short-term rating or
         may lack the structural and/or legal protections necessary to ensure
         the timely payment of purchase price upon demand.

Description of Moody's Short-Term Ratings

      Moody's Commercial Paper ratings are opinions of the ability of issuers
to honor short-term financial obligations not having an original maturity in
excess of thirteen months. Moody's employs the following three designations,
all judged to be investment grade, to indicate the relative repayment capacity
of rated issuers:

P-1      Issuers (or supporting institutions) rated Prime-1 have a superior
         ability to repay short-term debt obligations.

P-2      Issuers (or supporting institutions) rated Prime-2 have a strong
         ability to repay short-term debt obligations.

P-3      Issuers (or supporting institutions) rated Prime-3 have an acceptable
         ability to repay short-term obligations.

NP       Issuers (or supporting institutions) rated Not Prime do not fall
         within any of the Prime rating categories.

Description of Standard & Poor's, a Division of The McGraw-Hill Companies,
Inc. ("Standard & Poor's"), Debt Ratings

      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 program.
It takes into consideration the creditworthiness of guarantors, insurers, or
other forms of credit enhancement on the obligation.



                                     A-2
<PAGE>

      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.

      The issue credit ratings are based on current information furnished by
the obligors or obtained by Standard & Poor's from other sources Standard &
Poor's considers reliable. Standard & Poor's 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.

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

      I.    Likelihood of payment--capacity and willingness of the obligor as
            to the timely payment of interest and repayment of principal in
            accordance with the terms of the obligation;

      II.   Nature of and provisions of the obligation;

      III.  Protection afforded to, 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.

Long Term Issue Credit Ratings

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

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

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 similar action if payments
         on an obligation are jeopardized.

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.



                                     A-3
<PAGE>

         This rating, however, while addressing credit quality subsequent to the
         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        This symbol is attached to the ratings of instruments with
         significant noncredit risks. It highlights risks to principal or
         volatility of expected returns which are not addressed in the credit
         rating.

N.R.     This indicates that no rating has been requested, that there is
         insufficient information on which to base a rating, or that Standard
         & Poor's does not rate a particular obligation as a matter of policy.

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.

Description of Standard & Poor's Short-Term Issue Credit Ratings

      A Standard & Poor's short-term issue credit rating is a current
assessment of the likelihood of timely payment of debt having an original
maturity of no more than three years. 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 interest payments or principal payments
         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 will also be
         used upon the filing of a bankruptcy petition or the taking of a
         similar action if payments on an obligation are jeopardized.

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



                                     A-4
<PAGE>

         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.

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.

      A short-term issue credit rating is not a recommendation to purchase or
sell a security. The ratings are based on current information furnished to
Standard & Poor's by the issuer or obtained by Standard & Poor's from other
sources it considers reliable. The ratings may be changed, suspended, or
withdrawn as a result of changes in, or unavailability of, such information.

      A Standard & Poor's note rating 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.

      --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.

Description of Fitch Ratings' ("Fitch") Investment Grade Bond Ratings

      Fitch investment grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The rating
represents Fitch's assessment of the issuer's ability to meet the obligations
of a specific debt issue or class of debt in a timely manner.

      The rating takes into consideration special features of the issue, its
relationship to other obligations of the issuer, the current and prospective
financial condition and operating performance of the issuer and any guarantor,
as well as the economic and political environment that might affect the
issuer's future financial strength and credit quality.

      Fitch ratings do not reflect any credit enhancement that may be provided
by insurance policies or financial guarantees unless otherwise indicated.



                                     A-5
<PAGE>

      Bonds carrying the same rating are of similar but not necessarily
identical credit quality since the rating categories do not fully reflect
small differences in the degrees of credit risk.

      Fitch ratings are not recommendations to buy, sell, or hold any
security. Ratings do not comment on the adequacy of market price, the
suitability of any security for a particular investor, or the tax exempt
nature or taxability of payments made in respect of any security.

      Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such
information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.

AAA      Bonds considered to be investment grade and of the highest credit
         quality. The obligor has an exceptionally strong ability to pay
         interest and repay principal, which is unlikely to be affected by
         reasonably foreseeable events.

AA       Bonds considered to be investment grade and of very high credit
         quality. The obligor's ability to pay interest and repay principal is
         very strong, although not quite as strong as bonds rated "AAA."
         Because bonds rated in the "AAA" and "AA" categories are not
         significantly vulnerable to foreseeable future developments, short
         term debt of these issuers is generally rated "F-1+."

A        Bonds considered to be investment grade and of high credit quality.
         The obligor's ability to pay interest and repay principal is
         considered to be strong, but may be more vulnerable to adverse
         changes in economic conditions and circumstances than bonds with
         higher ratings.

BBB      Bonds considered to be investment grade and of satisfactory-credit
         quality. The obligor's ability to pay interest and repay principal is
         considered to be adequate. Adverse changes in economic conditions and
         circumstances, however, are more likely to have adverse impact on
         these bonds, and therefore impair timely payment. The likelihood that
         the ratings of these bonds will fall below investment grade is higher
         than for bonds with higher ratings.

Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus
and minus signs, however, are not used in the "AAA" category.

Description of Fitch's Speculative Grade Bond Ratings

      Fitch speculative grade bond ratings provide a guide to investors in
determining the credit risk associated with a particular security. The ratings
("BB" to "C") represent Fitch's assessment of the likelihood of timely payment
of principal and interest in accordance with the terms of obligation for bond
issues not in default. For defaulted bonds, the rating ("DDD" to "D") is an
assessment of the ultimate recovery value through reorganization or
liquidation. The rating takes into consideration special features of the
issue, its relationship to other obligations of the issuer, the current and
prospective financial condition and operating performance of the issuer and
any guarantor, as well as the economic and political environment that might
affect the issuer's future financial strength.

      Bonds that have the rating are of similar but not necessarily identical
credit quality since rating categories cannot fully reflect the differences in
degrees of credit risk.

BB       Bonds are considered speculative. The obligor's ability to pay
         interest and repay principal may be affected over time by adverse
         economic changes. However, business and financial alternatives can be
         identified which could assist the obligor in satisfying its debt
         service requirements.

B        Bonds are considered highly speculative. While bonds in this class
         are currently meeting debt service requirements, the probability of
         continued timely payment of principal and interest reflects the
         obligor's limited margin of safety and the need for reasonable
         business and economic activity throughout the life of the issue.



                                     A-6
<PAGE>

CCC      Bonds have certain identifiable characteristics which, if not
         remedied, may lead to default. The ability to meet obligations
         requires an advantageous business and economic environment.

CC       Bonds are minimally protected. Default in payment of interest and/or
         principal seems probable over time.

C        Bonds are in imminent default in payment of interest or principal.

D        Bonds are in default on interest and/or principal payments.  Such
DD       bonds are extremely speculative and should be valued on the basis of
DDD      their ultimate recovery value in liquidation or reorganization of
         the obligor.  "DDD" represents the highest potential for recovery on
         these bonds, and "D" represents the lowest potential for recovery.

Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus
and minus signs, however, are not used in the "DDD," "DD," or "D" categories.

Description of Fitch's Short Term Ratings

      Fitch's short term ratings apply to debt obligations that are payable on
demand or have original maturities of up to three years, including commercial
paper, certificates of deposit, medium-term notes, and investment notes.

      The short term rating places greater emphasis than a long term rating on
the existence of liquidity necessary to meet the issuer's obligations in a
timely manner.

      Fitch short term ratings are as follows:

F-1+         Exceptionally Strong Credit Quality.  Issues assigned this rating
             are regarded as having the strongest degree of assurance for timely
             payment.

F-1          Very Strong Credit Quality. Issues assigned this rating reflect an
             assurance of timely payment only slightly less in degree than
             issues rated "F-1+."

F-2          Good Credit Quality. Issues assigned this rating have a
             satisfactory degree of assurance for timely payment, but the
             margin of safety is not as great as for issues assigned "F-1+" and
             "F-1" ratings.

F-3          Fair Credit Quality. Issues assigned this rating have
             characteristics suggesting that the degree of assurance for timely
             payment is adequate; however, near-term adverse changes could
             cause these securities to be rated below investment grade.

F-S          Weak Credit Quality. Issues assigned this rating have
             characteristics suggesting a minimal degree of assurance for
             timely payment and are vulnerable to near-term adverse changes in
             financial and economic conditions.

D            Default. Issues assigned this rating are in actual or imminent
             payment default.

LOC          The symbol "LOC" indicates that the rating is based on a letter of
             credit issued by a commercial bank.

NR           Indicates that Fitch does not rate the specific issue.

Conditional  A conditional rating is premised on the successful completion of a
             project or the occurrence of a specific event.

Suspended    A rating is suspended when Fitch deems the amount of information
             available from the issuer to be inadequate for rating purposes.



                                     A-7
<PAGE>

Withdrawn    A rating will be withdrawn when an issue matures or is called or
             refinanced and, at Fitch's discretion, when an issuer fails to
             furnish proper and timely information.

FitchAlert   Ratings are placed on FitchAlert to notify investors of an
             occurrence that is likely to result in a rating change and the
             likely direction of such change. These are designated as
             "Positive," indicating a potential upgrade, "Negative," for
             potential downgrade, or "Evolving," where ratings may be raised or
             lowered. FitchAlert is relatively short term, and should be
             resolved within 12 months.

Ratings Outlook: An outlook is used to describe the most likely direction of
any rating change over the intermediate term. It is described as "Positive" or
"Negative." The absence of a designation indicates a stable outlook.

                                  APPENDIX B

                             SETTLEMENT PROCEDURES

      The following summary of Settlement Procedures sets forth the procedures
expected to be followed in connection with the settlement of each Auction and
will be incorporated by reference in the Auction Agent Agreement and each
Broker-Dealer Agreement. Nothing contained in this Appendix B constitutes a
representation by the Fund that in each Auction each party referred to herein
actually will perform the procedures described herein to be performed by such
party. Capitalized terms used herein shall have the respective meanings
specified in the Glossary in the prospectus or this Appendix B hereto, as the
case may be.

            (a) On each Auction Date, the Auction Agent shall notify by
      telephone or through the Auction Agent's Processing System the
      Broker-Dealers that participated in the Auction held on such Auction
      Date and submitted an Order on behalf of any Beneficial Owner or
      Potential Beneficial Owner of:

                  (i) the Applicable Rate fixed for the next succeeding
            Dividend Period;

                  (ii) whether Sufficient Clearing Bids existed for the
            determination of the Applicable Rate;

                  (iii) if such Broker-Dealer (a "Seller's Broker-Dealer")
            submitted a Bid or a Sell Order on behalf of a Beneficial Owner,
            the number of shares, if any, of AMPS to be sold by such
            Beneficial Owner;

                  (iv) if such Broker-Dealer (a "Buyer's Broker-Dealer")
            submitted a Bid on behalf of a Potential Beneficial Owner, the
            number of shares, if any, of AMPS to be purchased by such
            Potential Beneficial Owner;

                  (v) if the aggregate number of shares of AMPS to be sold by
            all Beneficial Owners on whose behalf such Broker-Dealer submitted
            a Bid or a Sell Order exceeds the aggregate number of shares of
            AMPS to be purchased by all Potential Beneficial Owners on whose
            behalf such Broker-Dealer submitted a Bid, the name or names of
            one or more Buyer's Broker-Dealers (and the name of the Agent
            Member, if any, of each such Buyer's Broker-Dealer) acting for one
            or more purchasers of such excess number of shares of AMPS and the
            number of such shares to be purchased from one or more Beneficial
            Owners on whose behalf such Broker-Dealer acted by one or more
            Potential Beneficial Owners on whose behalf each of such Buyer's
            Broker-Dealers acted;

                  (vi) if the aggregate number of shares of AMPS to be
            purchased by all Potential Beneficial Owners on whose behalf such
            Broker-Dealer submitted a Bid exceeds the aggregate number of
            shares of AMPS to be sold by all Beneficial Owners on whose behalf
            such Broker-Dealer submitted a Bid or a Sell Order, the name or
            names of one or more Seller's Broker-Dealers (and the name of the
            Agent Member, if any, of each such Seller's Broker-Dealer) acting
            for one or more sellers of such excess number of shares of AMPS
            and the number of such shares to be sold to one or more Potential
            Beneficial Owners on whose behalf such Broker-Dealer acted by one
            or more Beneficial Owners on whose behalf each of such Seller's
            Broker-Dealers acted; and

                  (vii) the Auction Date of the next succeeding Auction with
            respect to the AMPS.

            (b) On each Auction Date, each Broker-Dealer that submitted an
      Order on behalf of any Beneficial Owner or Potential Beneficial Owner
      shall:

                  (i) in the case of a Broker-Dealer that is a Buyer's
            Broker-Dealer, instruct each Potential Beneficial Owner on whose
            behalf such Broker-Dealer submitted a Bid that was accepted, in
            whole or in part, to instruct such Potential Beneficial Owner's
            Agent Member to pay to such Broker-Dealer (or its Agent Member)
            through the Securities Depository the amount

                                     B-1
<PAGE>

            necessary to purchase the number of shares of AMPS to be purchased
            pursuant to such Bid against receipt of such shares and advise
            such Potential Beneficial Owner of the Applicable Rate for the
            next succeeding Dividend Period;

                  (ii) in the case of a Broker-Dealer that is a Seller's
            Broker-Dealer, instruct each Beneficial Owner on whose behalf such
            Broker-Dealer submitted a Sell Order that was accepted, in whole
            or in part, or a Bid that was accepted, in whole or in part, to
            instruct such Beneficial Owner's Agent Member to deliver to such
            Broker-Dealer (or its Agent Member) through the Securities
            Depository the number of shares of AMPS to be sold pursuant to
            such Order against payment therefor and advise any such Beneficial
            Owner that will continue to hold shares of AMPS of the Applicable
            Rate for the next succeeding Dividend Period;

                  (iii) advise each Beneficial Owner on whose behalf such
            Broker-Dealer submitted a Hold Order of the Applicable Rate for
            the next succeeding Dividend Period;

                  (iv) advise each Beneficial Owner on whose behalf such
            Broker-Dealer submitted an Order of the Auction Date for the next
            succeeding Auction; and

                  (v) advise each Potential Beneficial Owner on whose behalf
            such Broker-Dealer submitted a Bid that was accepted, in whole or
            in part, of the Auction Date for the next succeeding Auction.

            (c) On the basis of the information provided to it pursuant to (a)
      above, each Broker-Dealer that submitted a Bid or a Sell Order on behalf
      of a Potential Beneficial Owner or a Beneficial Owner shall, in such
      manner and at such time or times as in its sole discretion it may
      determine, allocate any funds received by it pursuant to (b)(i) above
      and any shares of AMPS received by it pursuant to (b)(ii) above among
      the Potential Beneficial Owners, if any, on whose behalf such
      Broker-Dealer submitted Bids, the Beneficial Owners, if any, on whose
      behalf such Broker-Dealer submitted Bids that were accepted or Sell
      Orders, and any Broker-Dealer or Broker-Dealers identified to it by the
      Auction Agent pursuant to (a)(v) or (a)(vi) above.

            (d) On each Auction Date:

                  (i) each Potential Beneficial Owner and Beneficial Owner
            shall instruct its Agent Member as provided in (b)(i) or (ii)
            above, as the case may be;

                  (ii) each Seller's Broker-Dealer which is not an Agent
            Member of the Securities Depository shall instruct its Agent
            Member to (A) pay through the Securities Depository to the Agent
            Member of the Beneficial Owner delivering shares to such
            Broker-Dealer pursuant to (b)(ii) above the amount necessary to
            purchase such shares against receipt of such shares, and (B)
            deliver such shares through the Securities Depository to a Buyer's
            Broker-Dealer (or its Agent Member) identified to such Seller's
            Broker-Dealer pursuant to (a)(v) above against payment therefor;
            and

                  (iii) each Buyer's Broker-Dealer which is not an Agent
            Member of the Securities Depository shall instruct its Agent
            Member to (A) pay through the Securities Depository to a Seller's
            Broker-Dealer (or its Agent Member) identified pursuant to (a)(vi)
            above the amount necessary to purchase the shares to be purchased
            pursuant to (b)(i) above against receipt of such shares, and (B)
            deliver such shares through the Securities Depository to the Agent
            Member of the purchaser thereof against payment therefor.

            (e) On the day after the Auction Date:

                  (i) each Bidder's Agent Member referred to in (d)(i) above
            shall instruct the Securities Depository to execute the
            transactions described in (b)(i) or (ii) above, and the Securities
            Depository shall execute such transactions;


                                     B-2
<PAGE>

                  (ii) each Seller's Broker-Dealer or its Agent Member shall
            instruct the Securities Depository to execute the transactions
            described in (d)(ii) above, and the Securities Depository shall
            execute such transactions; and

                  (iii) each Buyer's Broker-Dealer or its Agent Member shall
            instruct the Securities Depository to execute the transactions
            described in (d)(iii) above, and the Securities Depository shall
            execute such transactions.

            (f) If a Beneficial Owner selling shares of AMPS in an Auction
      fails to deliver such shares (by authorized book-entry), a Broker-Dealer
      may deliver to the Potential Beneficial Owner on behalf of which it
      submitted a Bid that was accepted a number of whole shares of AMPS that
      is less than the number of shares that otherwise was to be purchased by
      such Potential Beneficial Owner. In such event, the number of shares of
      AMPS to be so delivered shall be determined solely by such
      Broker-Dealer. Delivery of such lesser number of shares shall constitute
      good delivery. Notwithstanding the foregoing terms of this paragraph
      (f), any delivery or non-delivery of shares which shall represent any
      departure from the results of an Auction, as determined by the Auction
      Agent, shall be of no effect unless and until the Auction Agent shall
      have been notified of such delivery or non-delivery in accordance with
      the provisions of the Auction Agent Agreement and the Broker-Dealer
      Agreements.

                                     B-3

                              AUCTION PROCEDURES

      The following procedures will be set forth in provisions of the Articles
Supplementary relating to the AMPS, and will be incorporated by reference in
the Auction Agent Agreement and each Broker-Dealer Agreement. The terms not

prospectus. Nothing contained in this Appendix C constitutes a representation
by the Fund that in each Auction each party referred to herein actually will
perform the procedures described herein to be performed by such party.

Paragraph 10(a) Certain Definitions.

      As used in this Paragraph 10, the following terms shall have the
following meanings, unless the context otherwise requires:

            (i) "AMPS" shall mean the shares of AMPS being auctioned pursuant
      to this Paragraph 10.

            (ii) "Auction Date" shall mean the first Business Day preceding
      the first day of a Dividend Period.

            (iii) "Available AMPS" shall have the meaning specified in
      Paragraph 10(d)(i) below.

            (iv) "Bid" shall have the meaning specified in Paragraph 10(b)(i)
      below.

            (vii) "Maximum Applicable Rate" for any Dividend Period will be
      the higher of the Applicable Percentage of the Reference Rate or the
      Applicable Spread plus the Reference Rate. The Applicable Percentage and
      the Applicable Spread will be determined based on (i) the lower of the
      credit rating or ratings assigned on such date to such shares by Moody's
      and S&P (or if Moody's or S&P or both shall not make such rating
      available, the equivalent of either or both of such ratings by a
      Substitute Rating Agency or two Substitute Rating Agencies or, in the
      event that only one such rating shall be available, such rating) and
      (ii) whether the Fund has provided notification to the Auction Agent
      prior to the Auction establishing the Applicable Rate for any dividend
      that net capital gains or other taxable income will be included in such
      dividend on shares of AMPS as follows:

      The Applicable Percentage and the Applicable Spread as so determined may
be further subject to upward but not downward adjustment in the discretion of
the Board of Directors of the Fund after consultation with the Broker-Dealers,
provided that immediately following any such increase the Fund would be in
compliance with the AMPS Basic Maintenance Amount. Subject to the provisions
of paragraph 12 of the Articles Supplementary entitled "Termination of Rating
Agency Provisions," the Fund shall take all reasonable action necessary to
enable S&P and Moody's to provide a rating for the AMPS. If either S&P or
Moody's shall not make such a rating available or if neither S&P nor Moody's
shall make such a rating available, subject to the provisions of paragraph 12
of the Articles Supplementary entitled "Termination of Rating Agency
Provisions," Merrill Lynch, Pierce, Fenner &

Smith Incorporated or its affiliates and successors, after obtaining the
Fund's approval, shall select a NRSRO or two NRSROs to act as a Substitute

      10(b)(i) below.

            (ix) "Sell Order" shall have the meaning specified in Paragraph

      Orders obtained by it for the Auction to be conducted on such Auction

Paragraph 10(b) Orders by Beneficial Owners, Potential Beneficial Owners,
Existing Holders And Potential Holders.

      (i) Unless otherwise permitted by the Fund, Beneficial Owners and
Potential Beneficial Owners may only participate in Auctions through their
Broker-Dealers. Broker-Dealers will submit the Orders of their respective
customers who are Beneficial Owners and Potential Beneficial Owners to the
Auction Agent, designating themselves as Existing Holders in respect of shares
subject to Orders submitted or deemed submitted to them by Beneficial Owners
and as Potential Holders in respect of shares subject to Orders submitted to
them by Potential Beneficial Owners. A Broker-Dealer may also hold shares of
AMPS in its own account as a Beneficial Owner. A Broker-Dealer may thus submit
Orders to the Auction Agent as a Beneficial Owner or a Potential Beneficial
Owner and therefore participate in an Auction as an Existing Holder or
Potential Holder on behalf of both itself and its customers. On or prior to
the Submission Deadline on each Auction Date:

            (A) each Beneficial Owner may submit to its Broker-Dealer
      information as to:

                  (1) the number of outstanding shares, if any, of AMPS held
            by such Beneficial Owner which such Beneficial Owner desires to
            continue to hold without regard to the Applicable Rate for the
            next succeeding Dividend Period;

                  (2) the number of outstanding shares, if any, of AMPS held
            by such Beneficial Owner which such Beneficial Owner desires to
            continue to hold, provided that the Applicable Rate for the next
            succeeding Dividend Period shall not be less than the rate per
            annum specified by such Beneficial Owner; and/or

                  (3) the number of outstanding shares, if any, of AMPS held
            by such Beneficial Owner which such Beneficial Owner offers to
            sell without regard to the Applicable Rate for the next succeeding
            Dividend Period; and

            (B) each Broker-Dealer, using a list of Potential Beneficial
      Owners that shall be maintained in good faith for the purpose of
      conducting a competitive Auction, shall contact Potential Beneficial
      Owners, including Persons that are not Beneficial Owners, on such list
      to determine the number of

                                     C-2

<PAGE>

      outstanding shares, if any, of AMPS which each such Potential Beneficial
      Owner offers to purchase, provided that the Applicable Rate for the next
      succeeding Dividend Period shall not be less than the rate per annum
      specified by such Potential Beneficial Owner.

      For the purposes hereof, the communication by a Beneficial Owner or
Potential Beneficial Owner to a Broker-Dealer, or the communication by a
Broker-Dealer acting for its own account to the Auction Agent, of information
referred to in clause (A) or (B) of this Paragraph 10(b)(i) is hereinafter
referred to as an "Order" and each Beneficial Owner and each Potential
Beneficial Owner placing an Order, including a Broker-Dealer acting in such
capacity for its own account, is hereinafter referred to as a "Bidder"; an
Order containing the information referred to in clause (A)(1) of this
Paragraph 10(b)(i) is hereinafter referred to as a "Hold Order"; an Order
containing the information referred to in clause (A)(2) or (B) of this
Paragraph 10(b)(i) is hereinafter referred to as a "Bid"; and an Order
containing the information referred to in clause (A)(3) of this Paragraph
10(b)(i) is hereinafter referred to as a "Sell Order." Inasmuch as a
Broker-Dealer participates in an Auction as an Existing Holder or a Potential
Holder only to represent the interests of a Beneficial Owner or Potential
Beneficial Owner, whether it be its customers or itself, all discussion herein
relating to the consequences of an Auction for Existing Holders and Potential
Holders also applies to the underlying beneficial ownership interests
represented.

      (ii) (A) A Bid by an Existing Holder shall constitute an irrevocable
offer to sell:

            (1) the number of outstanding shares of AMPS specified in such Bid
      if the Applicable Rate determined on such Auction Date shall be less
      than the rate per annum specified in such Bid; or

            (2) such number or a lesser number of outstanding shares of AMPS
      to be determined as set forth in Paragraph 10(e)(i)(D) if the Applicable
      Rate determined on such Auction Date shall be equal to the rate per
      annum specified therein; or

            (3) a lesser number of outstanding shares of AMPS to be determined
      as set forth in Paragraph 10(e)(ii)(C) if such specified rate per annum
      shall be higher than the Maximum Applicable Rate and Sufficient Clearing
      Bids do not exist.

      (B) A Sell Order by an Existing Holder shall constitute an irrevocable
offer to sell:

            (1) the number of outstanding shares of AMPS specified in such
      Sell Order, or

            (2) such number or a lesser number of outstanding shares of AMPS
      to be determined as set forth in Paragraph 10(e)(ii)(C) if Sufficient
      Clearing Bids do not exist.

      (C) A Bid by a Potential Holder shall constitute an irrevocable offer to
purchase:

            (1) the number of outstanding shares of AMPS specified in such Bid
      if the Applicable Rate determined on such Auction Date shall be higher
      than the rate per annum specified in such Bid; or

            (2) such number or a lesser number of outstanding shares of AMPS
      to be determined as set forth in Paragraph 10(e)(i)(E) if the Applicable
      Rate determined on such Auction Date shall be equal to the rate per
      annum specified therein.

Paragraph 10(c) Submission of Orders by Broker-Dealers to Auction Agent.

      (i) Each Broker-Dealer shall submit in writing or through a mutually
acceptable electronic means to the Auction Agent prior to the Submission
Deadline on each Auction Date all Orders obtained by such Broker-Dealer,
designating itself (unless otherwise permitted by the Fund) as an Existing
Holder in respect of shares subject to Orders submitted or deemed submitted to
it by Beneficial Owners and as a Potential Holder in respect of shares subject
to Orders submitted to it by Potential Beneficial Owners, and specifying with
respect to each Order:

                                     C-3

<PAGE>

            (A) the name of the Bidder placing such Order (which shall be the
      Broker-Dealer unless otherwise permitted by the Fund);

            (B) the aggregate number of outstanding shares of AMPS that are
      the subject of such Order;

            (C) to the extent that such Bidder is an Existing Holder

                  (1) the number of outstanding shares, if any, of AMPS
            subject to any Hold Order placed by such Existing Holder;

                  (2) the number of outstanding shares, if any, of AMPS
            subject to any Bid placed by such Existing Holder and the rate per
            annum specified in such Bid; and

                  (3) the number of outstanding shares, if any, of AMPS
            subject to any Sell Order placed by such Existing Holder; and

            (D) to the extent such Bidder is a Potential Holder, the rate per
      annum specified in such Potential Holder's Bid.

      (ii) If any rate per annum specified in any Bid contains more than three
figures to the right of the decimal point, the Auction Agent shall round such
rate up to the next highest one-thousandth (.001) of 1%.

      (iii) If an Order or Orders covering all of the outstanding shares of
AMPS held by an Existing Holder are not submitted to the Auction Agent prior
to the Submission Deadline, the Auction Agent shall deem a Hold Order (in the
case of an Auction relating to a Dividend Period which is not a Special
Dividend Period of more than 28 days) and a Sell Order (in the case of an
Auction relating to a Special Dividend Period of more than 28 days) to have
been submitted on behalf of such Existing Holder covering the number of
outstanding shares of AMPS held by such Existing Holder and not subject to
Orders submitted to the Auction Agent.

      (iv) If one or more Orders on behalf of an Existing Holder covering in
the aggregate more than the number of outstanding shares of AMPS held by such
Existing Holder are submitted to the Auction Agent, such Orders shall be
considered valid as follows and in the following order of priority:

            (A) any Hold Order submitted on behalf of such Existing Holder
      shall be considered valid up to and including the number of outstanding
      shares of AMPS held by such Existing Holder; provided that if more than
      one Hold Order is submitted on behalf of such Existing Holder and the
      number of shares of AMPS subject to such Hold Orders exceeds the number
      of outstanding shares of AMPS held by such Existing Holder, the number
      of shares of AMPS subject to each of such Hold Orders shall be reduced
      pro rata so that such Hold Orders, in the aggregate, cover exactly the
      number of outstanding shares of AMPS held by such Existing Holder;

            (B) any Bids submitted on behalf of such Existing Holder shall be
      considered valid, in the ascending order of their respective rates per
      annum if more than one Bid is submitted on behalf of such Existing
      Holder, up to and including the excess of the number of outstanding
      shares of AMPS held by such Existing Holder over the number of shares of
      AMPS subject to any Hold Order referred to in Paragraph 10(c)(iv)(A)
      above (and if more than one Bid submitted on behalf of such Existing
      Holder specifies the same rate per annum and together they cover more
      than the remaining number of shares that can be the subject of valid
      Bids after application of Paragraph 10(c)(iv)(A) above and of the
      foregoing portion of this Paragraph 10(c)(iv)(B) to any Bid or Bids
      specifying a lower rate or rates per annum, the number of shares subject
      to each of such Bids shall be reduced pro rata so that such Bids, in the
      aggregate, cover exactly such remaining number of shares); and the
      number of shares, if any, subject to Bids not valid under this Paragraph
      10(c)(iv)(B) shall be treated as the subject of a Bid by a Potential
      Holder; and

            (C) any Sell Order shall be considered valid up to and including
      the excess of the number of outstanding shares of AMPS held by such
      Existing Holder over the number of shares of AMPS subject to

                                     C-4

<PAGE>

      Hold Orders referred to in Paragraph 10(c)(iv)(A) and Bids referred to
      in Paragraph 10(c)(iv)(B); provided that if more than one Sell Order is
      submitted on behalf of any Existing Holder and the number of shares of
      AMPS subject to such Sell Orders is greater than such excess, the number
      of shares of AMPS subject to each of such Sell Orders shall be reduced
      pro rata so that such Sell Orders, in the aggregate, cover exactly the
      number of shares of AMPS equal to such excess.

      (v) If more than one Bid is submitted on behalf of any Potential Holder,
each Bid submitted shall be a separate Bid with the rate per annum and number
of shares of AMPS therein specified.

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

Paragraph 10(d) Determination of Sufficient Clearing Bids, Winning Bid Rate
and Applicable Rate.

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

            (A) the excess of the total number of outstanding shares of AMPS
      over the number of outstanding shares of AMPS that are the subject of
      Submitted Hold Orders (such excess being hereinafter referred to as the
      "Available AMPS");

            (B) from the Submitted Orders whether the number of outstanding
      shares of AMPS that are the subject of Submitted Bids by Potential
      Holders specifying one or more rates per annum equal to or lower than
      the Maximum Applicable Rate exceeds or is equal to the sum of:

                  (1) the number of outstanding shares of AMPS that are the
            subject of Submitted Bids by Existing Holders specifying one or
            more rates per annum higher than the Maximum Applicable Rate, and

                  (2) the number of outstanding shares of AMPS that are
            subject to Submitted Sell Orders (if such excess or such equality
            exists (other than because the number of outstanding shares of
            AMPS in clauses (1) and (2) above are each zero because all of the
            outstanding shares of AMPS are the subject of Submitted Hold
            Orders), such Submitted Bids by Potential Holders hereinafter
            being referred to collectively as "Sufficient Clearing Bids"); and

                  (C) if Sufficient Clearing Bids exist, the lowest rate per
            annum specified in the Submitted Bids (the "Winning Bid Rate")
            that if:

                  (1) each Submitted Bid from Existing Holders specifying the
            Winning Bid Rate and all other submitted Bids from Existing
            Holders specifying lower rates per annum were rejected, thus
            entitling such Existing Holders to continue to hold the shares of
            AMPS that are the subject of such Submitted Bids, and

                  (2) each Submitted Bid from Potential Holders specifying the
            Winning Bid Rate and all other Submitted Bids from Potential
            Holders specifying lower rates per annum were accepted, thus
            entitling the Potential Holders to purchase the shares of AMPS
            that are the subject of such Submitted Bids,

      would result in the number of shares subject to all Submitted Bids
      specifying the Winning Bid Rate or a lower rate per annum being at least
      equal to the Available AMPS.

                                     C-5

<PAGE>

      (ii) Promptly after the Auction Agent has made the determinations
pursuant to Paragraph 10(d)(i), the Auction Agent shall advise the Fund of the
Maximum Applicable Rate and, based on such determinations, the Applicable Rate
for the next succeeding Dividend Period as follows:

            (A) if Sufficient Clearing Bids exist, that the Applicable Rate
      for the next succeeding Dividend Period shall be equal to the Winning
      Bid Rate;

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

            (C) if all of the outstanding shares of AMPS are the subject of
      Submitted Hold Orders, the Dividend Period next succeeding the Auction
      automatically shall be the same length as the immediately preceding
      Dividend Period and the Applicable Rate for the next succeeding Dividend
      Period shall be equal to 60% of the Reference Rate (or 90% of such rate
      if the Fund has provided notification to the Auction Agent prior to
      establishing the Applicable Rate for any dividend that net capital gain
      or other taxable income will be included in such dividend on shares of
      AMPS) on the date of the Auction.

Paragraph 10(e) Acceptance and Rejection of Submitted Bids and Submitted Sell
Orders and Allocation of Shares.

      Based on the determinations made pursuant to Paragraph 10(d)(i), the
Submitted Bids and Submitted Sell Orders shall be accepted or rejected and the
Auction Agent shall take such other action as set forth below:

            (i) If Sufficient Clearing Bids have been made, subject to the
      provisions of Paragraph 10(e)(iii) and Paragraph 10(e)(iv), Submitted
      Bids and Submitted Sell Orders shall be accepted or rejected in the
      following order of priority and all other Submitted Bids shall be
      rejected:

                  (A) the Submitted Sell Orders of Existing Holders shall be
            accepted and the Submitted Bid of each of the Existing Holders
            specifying any rate per annum that is higher than the Winning Bid
            Rate shall be accepted, thus requiring each such Existing Holder
            to sell the outstanding shares of AMPS that are the subject of
            such Submitted Sell Order or Submitted Bid;

                  (B) the Submitted Bid of each of the Existing Holders
            specifying any rate per annum that is lower than the Winning Bid
            Rate shall be rejected, thus entitling each such Existing Holder
            to continue to hold the outstanding shares of AMPS that are the
            subject of such Submitted Bid;

                  (C) the Submitted Bid of each of the Potential Holders
            specifying any rate per annum that is lower than the Winning Bid
            Rate shall be accepted;

                  (D) the Submitted Bid of each of the Existing Holders
            specifying a rate per annum that is equal to the Winning Bid Rate
            shall be rejected, thus entitling each such Existing Holder to
            continue to hold the outstanding shares of AMPS that are the
            subject of such Submitted Bid, unless the number of outstanding
            shares of AMPS subject to all such Submitted Bids shall be greater
            than the number of outstanding shares of AMPS ("Remaining Shares")
            equal to the excess of the Available AMPS over the number of
            outstanding shares of AMPS subject to Submitted Bids described in
            Paragraph 10(e)(i)(B) and Paragraph 10(e)(i)(C), in which event
            the Submitted Bids of each such Existing Holder shall be accepted,
            and each such Existing Holder shall be required to sell
            outstanding shares of AMPS, but only in an amount equal to the
            difference between (1) the number of outstanding shares of AMPS
            then held by such Existing Holder subject to such Submitted Bid
            and (2) the number of shares of AMPS obtained by multiplying (x)
            the number of Remaining Shares by (y) a fraction the numerator of
            which shall be the number of outstanding shares of AMPS held by
            such Existing Holder subject to such Submitted Bid and the
            denominator of which shall be the sum of the numbers of
            outstanding shares of AMPS subject to such

                                     C-6

<PAGE>

            Submitted Bids made by all such Existing Holders that specified a
            rate per annum equal to the Winning Bid Rate; and

                  (E) the Submitted Bid of each of the Potential Holders
            specifying a rate per annum that is equal to the Winning Bid Rate
            shall be accepted but only in an amount equal to the number of
            outstanding shares of AMPS obtained by multiplying (x) the
            difference between the Available AMPS and the number of
            outstanding shares of AMPS subject to Submitted Bids described in
            Paragraph 10(e)(i)(B), Paragraph 10(e)(i)(C) and Paragraph
            10(e)(i)(D) by (y) a fraction the numerator of which shall be the
            number of outstanding shares of AMPS subject to such Submitted Bid
            and the denominator of which shall be the sum of the number of
            outstanding shares of AMPS subject to such Submitted Bids made by
            all such Potential Holders that specified rates per annum equal to
            the Winning Bid Rate.

            (ii) If Sufficient Clearing Bids have not been made (other than
      because all of the outstanding shares of AMPS are subject to Submitted
      Hold Orders), subject to the provisions of Paragraph 10(e)(iii),
      Submitted Orders shall be accepted or rejected as follows in the
      following order of priority and all other Submitted Bids shall be
      rejected:

                  (A) the Submitted Bid of each Existing Holder specifying any
            rate per annum that is equal to or lower than the Maximum
            Applicable Rate shall be rejected, thus entitling such Existing
            Holder to continue to hold the outstanding shares of AMPS that are
            the subject of such Submitted Bid;

                  (B) the Submitted Bid of each Potential Holder specifying
            any rate per annum that is equal to or lower than the Maximum
            Applicable Rate shall be accepted, thus requiring such Potential
            Holder to purchase the outstanding shares of AMPS that are the
            subject of such Submitted Bid; and

                  (C) the Submitted Bids of each Existing Holder specifying
            any rate per annum that is higher than the Maximum Applicable Rate
            shall be accepted and the Submitted Sell Orders of each Existing
            Holder shall be accepted, in both cases only in an amount equal to
            the difference between (1) the number of outstanding shares of
            AMPS then held by such Existing Holder subject to such Submitted
            Bid or Submitted Sell Order and (2) the number of shares of AMPS
            obtained by multiplying (x) the difference between the Available
            AMPS and the aggregate number of outstanding shares of AMPS
            subject to Submitted Bids described in Paragraph 10(e)(ii)(A) and
            Paragraph 10(e)(ii)(B) by (y) a fraction the numerator of which
            shall be the number of outstanding shares of AMPS held by such
            Existing Holder subject to such Submitted Bid or Submitted Sell
            Order and the denominator of which shall be the number of
            outstanding shares of AMPS subject to all such Submitted Bids and
            Submitted Sell Orders.

      (iii) If, as a result of the procedures described in Paragraph 10(e)(i)
or Paragraph 10(e)(ii), any Existing Holder would be entitled or required to
sell, or any Potential Holder would be entitled or required to purchase, a
fraction of a share of AMPS on any Auction Date, the Auction Agent shall, in
such manner as in its sole discretion it shall determine, round up or down the
number of shares of AMPS to be purchased or sold by any Existing Holder or
Potential Holder on such Auction Date so that each outstanding share of AMPS
purchased or sold by each Existing Holder or Potential Holder on such Auction
Date shall be a whole share of AMPS.

      (iv) If, as a result of the procedures described in Paragraph 10(e)(i),
any Potential Holder would be entitled or required to purchase less than a
whole share of AMPS on any Auction Date, the Auction Agent, in such manner as
in its sole discretion it shall determine, shall allocate shares of AMPS for
purchase among Potential Holders so that only whole shares of AMPS are
purchased on such Auction Date by any Potential Holder, even if such
allocation results in one or more of such Potential Holders not purchasing any
shares of AMPS on such Auction Date.

      (v) Based on the results of each Auction, the Auction Agent shall
determine, with respect to each Broker-Dealer that submitted Bids or Sell
Orders on behalf of Existing Holders or Potential Holders, the aggregate

                                     C-7

<PAGE>

number of the outstanding shares of AMPS to be purchased and the aggregate
number of outstanding shares of AMPS to be sold by such Potential Holders and
Existing Holders and, to the extent that such aggregate number of outstanding
shares to be purchased and such aggregate number of outstanding shares to be
sold differ, the Auction Agent shall determine to which other Broker-Dealer or
Broker-Dealers acting for one or more purchasers such Broker-Dealer shall
deliver, or from which other Broker-Dealer or Broker-Dealers acting for one or
more sellers such Broker-Dealer shall receive, as the case may be, outstanding
shares of AMPS.

Paragraph 10(f) Miscellaneous.

      The Fund may interpret the provisions of this Paragraph 10 to resolve
any inconsistency or ambiguity, remedy any formal defect or make any other
change or modification that does not substantially adversely affect the rights
of Beneficial Owners of AMPS. A Beneficial Owner or an Existing Holder (A) may
sell, transfer or otherwise dispose of shares of AMPS only pursuant to a Bid
or Sell Order in accordance with the procedures described in this Paragraph 10
or to or through a Broker-Dealer, provided that in the case of all transfers
other than pursuant to Auctions such Beneficial Owner or Existing Holder, its
Broker-Dealer, if applicable, or its Agent Member advises the Auction Agent of
such transfer and (B) except as otherwise required by law, shall have the
ownership of the shares of AMPS held by it maintained in book entry form by
the Securities Depository in the account of its Agent Member, which in turn
will maintain records of such Beneficial Owner's beneficial ownership. Neither
the Fund nor any affiliate (other than Merrill Lynch, Pierce, Fenner & Smith
Incorporated) shall submit an Order in any Auction. Any Beneficial Owner that
is an affiliate (other than Merrill Lynch, Pierce, Fenner & Smith
Incorporated) shall not sell, transfer or otherwise dispose of shares of AMPS
to any person other than the Fund. All of the outstanding shares of AMPS of a
series shall be represented by a single certificate registered in the name of
the nominee of the Securities Depository unless otherwise required by law or
unless there is no Securities Depository. If there is no Securities
Depository, at the Fund's option and upon its receipt of such documents as it
deems appropriate, any shares of AMPS may be registered in the Stock Register
in the name of the Beneficial Owner thereof and such Beneficial Owner
thereupon will be entitled to receive certificates therefor and required to
deliver certificates thereof or upon transfer or exchange thereof.

Item 30.  Indemnification.

      Reference is made to Section 2-418 of the General Corporation Law of the
State of Maryland, Article V of the Registrant's Articles of Incorporation,
Article VI of the Registrant's By-laws and Section 6 of the Purchase
Agreement, which provide for indemnification.

      Article VI of the By-laws provides that each officer and director of the
Registrant shall be indemnified by the Registrant to the full extent permitted
under the Maryland General Corporation Law, except that such indemnity shall
not protect any such person against any liability to the Registrant or any
stockholder thereof to which such person 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 or her office. Absent a court
determination that an officer or director seeking indemnification was not
liable on the merits or guilty of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his
or her office, the decision by the Registrant to indemnify such person must be
based upon the reasonable determination of independent legal counsel or the
vote of a majority of a quorum of non-party independent directors, after
review of the facts, that such officer or director is not guilty of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his or her office.

      Each officer and director of the Registrant claiming indemnification
within the scope of Article VI of the By-laws shall be entitled to advances
from the Registrant for payment of the reasonable expenses incurred by him or
her in connection with proceedings to which he or she is a party in the manner
and to the full extent permitted under the Maryland General Corporation Law;
provided, however, that the person seeking indemnification shall provide to
the Registrant a written affirmation of his or her good faith belief that the
standard of conduct necessary for indemnification by the Registrant has been
met and a written undertaking to repay any such advance, if it ultimately
should be determined that the standard of conduct has not been met, and
provided further that at least one of the following additional conditions is
met: (i) the person seeking indemnification shall provide a security in form
and amount acceptable to the Registrant for his or her undertaking; (ii) the
Registrant is insured against losses arising by reason of the advance; or
(iii) a majority of a quorum of non-party independent directors, or
independent legal counsel in a written opinion shall determine, based on a
review of facts readily available to the Registrant at the time the advance is
proposed to be made, that there is reason to believe that the person seeking
indemnification will ultimately be found to be entitled to indemnification.

      The Registrant may purchase insurance on behalf of an officer or
director protecting such person to the full extent permitted under the
Maryland General Corporation Law from liability arising from his or her
activities as officer or director of the Registrant. The Registrant, however,
may not purchase insurance on behalf of any officer or director of the
Registrant that protects or purports to protect such person from liability to
the Registrant or to its stockholders to which such officer or director 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
or her office.

                                     C-3

<PAGE>

      In Section 7 of the Purchase Agreement relating to the securities being
offered hereby, the Registrant agrees to indemnify Merrill Lynch and each
person, if any, who controls Merrill Lynch within the meaning of the
Securities Act of 1933 (the "1933 Act") against certain types of civil
liabilities arising in connection with the Registration Statement or
Prospectus and Statement of Additional Information.

      Insofar as indemnification for liabilities arising under the 1933 Act
may be provided to directors, officers and controlling persons of the
Registrant and Merrill Lynch, 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 1933 Act 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 connection with any
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 1933 Act and will be governed by the
final adjudication of such issue.
