                                           Shares
                      Muni Intermediate Duration Fund, Inc.
                                  Common Stock

                                   ----------

      Muni Intermediate Duration Fund, Inc. is a newly organized,
non-diversified, closed-end fund. The investment objective of the Fund is to
provide stockholders with high current income exempt from Federal income taxes.
The Fund seeks to achieve its objective by investing, as a fundamental policy,
at least 80% of its net assets (including assets acquired from the sale of
preferred stock), plus the amount 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 exempt from Federal income taxes. 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. Under normal market conditions and after the initial investment
period following this offering (expected to be approximately three months), the
Fund will invest, as a non-fundamental policy, at least 80% of its net assets
(including assets acquired from the sale of preferred stock), plus the amount of
any borrowings for investment purposes, in municipal obligations with an
option-adjusted duration, as calculated by the Fund's investment adviser, of
three to ten years. The Fund expects to maintain, under normal market
conditions, a dollar-weighted average portfolio option-adjusted duration, as
calculated by the Fund's investment adviser, of three to ten years, including
after giving effect to leverage. There can be no assurance that the Fund's
investment objective will be realized.

      Investing in the Fund's common stock involves certain risks that are

(1)   To the extent that the Fund's offering costs otherwise do not exceed $.03
      per share of common stock, the Fund has agreed to pay the underwriters up
      to $.005 per share of common stock as a partial reimbursement of expenses
      incurred in connection with the offering. However, in no event will the
      Fund pay offering costs (other than the underwriting discount, but
      including the partial reimbursement to the underwriters) in excess of $.03
      per share of common stock. See "Underwriting."

(2)   The Fund's investment adviser has agreed to pay all organizational
      expenses of the Fund. The investment adviser or an affiliate will pay the
      amount by which the offering costs of the Fund (other than the
      underwriting discount and the $.005 per share partial reimbursement of
      expenses to the underwriters) exceeds $.03 per share of common stock. The
      estimated offering expenses to be incurred by the Fund are $ .


      The underwriters may also purchase up to an additional shares at the
public offering price, less the underwriting discount, within 45 days from the
date of this prospectus to cover overallotments.

                 The date of this prospectus is August , 2003.




(continued from previous page)

      Because the Fund is newly organized, its shares have no history of public
trading. Shares of closed-end investment companies frequently trade at a price
lower than their net asset value. This is commonly referred to as "trading at a
discount." The risk may be greater for investors expecting to sell their shares
in a relatively short period after completion of the public offering. The Fund
plans to apply to list its shares on the New York Stock Exchange or another
national securities exchange under the symbol "MUI."

      The Fund may leverage through borrowings or the issuance of preferred
stock or debt securities. Within approximately three months after completion of
this offering of common stock, the Fund intends to offer shares of preferred
stock representing approximately 35% of the Fund's capital, or approximately 54%
of the Fund's common stock equity, immediately after the issuance of such
preferred stock. There can be no assurance, however, that preferred stock
representing such percentage of the Fund's capital will actually be issued. The
use of preferred stock to leverage the common stock can create special risks.
There can be no assurance that a leveraging strategy will be successful during
any period in which it is employed.

                               PROSPECTUS SUMMARY

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

The Fund                   Muni Intermediate Duration Fund, Inc. is a newly
                           organized, non-diversified, closed-end fund.

The Offering               The Fund is offering     shares of common stock at an
                           initial offering price of $15.00 per share through a
                           group of underwriters led by Merrill Lynch, Pierce,
                           Fenner & Smith Incorporated ("Merrill Lynch"). You
                           must purchase at least 100 shares of common stock to
                           participate in this offering. The underwriters may
                           purchase up to an additional       shares of common
                           stock within 45 days of the date of this prospectus
                           to cover overallotments, if any.

Investment Objective       The investment objective of the Fund is to provide
and Policies               stockholders with high current income exempt from
                           Federal income taxes. The Fund seeks to achieve its
                           objective by investing, as a fundamental policy, at
                           least 80% of its net assets (including assets
                           acquired from the sale of preferred stock), plus the
                           amount 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 exempt from Federal income tax ("Municipal
                           Bonds"). There can be no assurance that the Fund's
                           investment objective will be realized.

                           Under normal market conditions, and after the initial
                           investment period following this offering (expected
                           to be approximately three months), the Fund will
                           invest, as a non-fundamental policy, at least 80% of
                           net assets (including assets acquired from the sale
                           of preferred stock), plus the amount of any
                           borrowings for investment purposes, in Municipal
                           Bonds with an option-adjusted duration, as calculated
                           by Fund Asset Management, L.P. (the "Investment
                           Adviser"), of three to ten years. The Fund expects to
                           maintain under normal market conditions a
                           dollar-weighted average portfolio option-adjusted
                           duration, as calculated by the Investment Adviser, of
                           three to ten years, including after giving effect to
                           leverage. There is no limit on the remaining maturity
                           of each individual Municipal Bond investment by the
                           Fund. In general, the Fund does not intend its
                           investments to earn a large amount of interest income
                           that is not exempt from Federal income taxes.

                           Investment Grade Municipal Bonds. 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 one or more nationally recognized
                           statistical rating agencies or in unrated bonds
                           considered by the Investment Adviser to be of
                           comparable quality.

                           Junk Bonds. The Fund may invest up to 25% of its
                           total assets in junk 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. 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
--------------------------------------------------------------------------------


                                       5


--------------------------------------------------------------------------------
                           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 income 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

Use of Leverage by         Issuance of Preferred Stock. The Fund intends to
the Fund                   offer shares of preferred stock within approximately
                           three months after completion of this offering. Under
                           current market conditions it is anticipated that the
                           preferred stock will represent approximately 35% of
                           the Fund's capital, including the capital raised by
                           issuing the preferred stock, or approximately 54% of
                           the Fund's common stock equity. There can be no
                           assurance, however, that preferred stock will
                           actually be issued or, if issued, what percentage of
                           the Fund's capital it will represent. Issuing
                           preferred stock will result in the leveraging of the
                           Fund's common stock. Although the Board of Directors
                           has not yet determined the terms of the preferred
                           stock offering, the Fund expects that the preferred
                           stock will pay dividends that will be adjusted over
                           either relatively short term periods (generally 7 to
                           28 days) or medium term periods (up to five years)
                           and that the preferred stock dividend rate will be
                           based upon prevailing interest rates for debt
                           obligations of comparable maturity. The proceeds of
                           the preferred stock offering will be invested in
                           accordance with the Fund's investment objective. The
                           expenses of the preferred stock, which will be borne
                           by the Fund, will reduce the net asset value of the
                           Fund's common stock. During periods when the Fund has
                           preferred stock outstanding, the Fund will pay fees
                           to the Investment Adviser for its services that are
                           higher than if the Fund did not issue preferred stock
                           because the fees will be calculated on the basis of
                           the Fund's average daily net assets (including any
                           proceeds from the issuance of preferred stock), plus
                           the proceeds of any outstanding borrowings used for
                           leverage.

                           Potential Benefits of Leverage. Under normal market
                           conditions, the income earned on the Fund's portfolio
                           should exceed the dividend rate the Fund must pay to
                           the preferred stockholders. Thus, the Fund's use of
                           preferred stock should provide common stockholders
                           with a higher yield than they would receive if the
                           Fund were not leveraged, although no assurance can be
                           given that the issuance of preferred stock will
                           result in a higher yield or return to common
                           stockholders.

                           Risks of Leverage. The use of leverage creates
                           certain risks for common stockholders, including the
                           greater likelihood of higher volatility of the Fund's
                           yield, its net asset value and the market price of
                           its common stock. Changes in short term, medium term
                           and long term rates, and their relationship to each
                           other, could negatively impact the Fund's yield, net
                           asset value and market price of the common stock.
                           Furthermore, since any decline in the value of the
                           Fund's investments will affect only the common
                           stockholders, in a declining market the use of
                           leverage will cause the Fund's net asset value to
                           decrease more than it would if the Fund were not
                           leveraged. This decrease in net asset value will
                           likely also cause a decline in the market price for
                           shares of common stock. There can be no assurance
                           that the Fund will earn a higher yield or return on
                           its investment portfolio than the then current
                           dividend rate (and any additional distribution) it
                           pays on the preferred stock. Under certain
                           circumstances, when the Fund is required to allocate
                           taxable income to holders of preferred stock, the
                           Fund anticipates that the terms of the preferred
                           stock will require the Fund to make an additional
                           distribution to such holders in an amount
                           approximately equal to the tax liability resulting
                           from such allocation. Under certain conditions, the
                           benefits of leverage to common stockholders will be
                           reduced or eliminated, and the Fund's leveraged
                           capital structure could result in a lower yield or
                           return to common stockholders than if the Fund were
                           not leveraged.

                           In particular, during times of rising interest rates,
                           the market value of the Fund's portfolio investments
                           and, consequently, the net asset value of its shares
                           may decline. The Fund's leveraging of its portfolio
                           by issuing preferred stock may accentuate the
                           potential decline, since both the cost of issuing the
                           preferred stock and any decline in the value of the
                           portfolio investments (including investments
                           purchased with the proceeds of the preferred stock)
                           will be borne entirely by the holders of the common
                           stock. The Fund also may invest in inverse floating
                           obligations and similar securities that create
                           investment leverage, which may further accentuate any
                           decline. Any investor who purchases shares with
                           borrowed funds may experience an even greater
                           decline.

                           Distributions. When the Fund issues preferred stock,
                           common stockholders will receive all of the Fund's
                           net income that remains after it pays dividends (and
                           any additional distribution) on the preferred stock
                           and generally will be entitled to a pro rata share of
                           net realized capital gains. If the Fund is
                           liquidated, preferred stockholders will be entitled
                           to receive liquidating distributions before any
                           distribution is made to common stockholders. These
                           liquidating distributions are expected to equal the
                           original purchase price per share of the preferred
                           stock plus any accumulated and unpaid dividends and
                           additional distributions.

                           Redemption of Preferred Stock. The Fund may redeem
                           the preferred stock for any reason. For example, the
                           Fund may redeem all or part of the preferred stock if
                           the asset coverage for the preferred stock declines
                           below 200% or in order to maintain the asset coverage
                           guidelines established by a nationally recognized
                           statistical ratings organization that rates the
                           preferred stock.

                           Voting Rights. Preferred stockholders, voting as a
                           separate class, will be entitled to elect two of the
                           Fund's Directors. Common and preferred stockholders,
                           voting together as a single class, will be entitled
                           to elect the remaining Directors. If the Fund fails
                           to pay dividends to the preferred stockholders for
                           two full years, the holders of all outstanding shares
                           of preferred stock, voting as a separate class, would
                           then be entitled to elect a majority of the Fund's
                           Directors. The preferred stockholders also will vote
                           separately on certain other matters as required under
                           the Fund's Articles of Incorporation, as amended and
                           supplemented (the "Charter"), the Investment Company
                           Act of 1940, as amended (the "1940 Act"), and the
                           General Corporation Law of the State of Maryland.
                           Otherwise, common and preferred stockholders will
                           have equal voting rights (one vote per share) and
                           will vote together as a single class.

                           Ratings. Before it offers the preferred stock, the
                           Fund intends to apply to one or more nationally
                           recognized statistical ratings organizations for
                           ratings on the preferred stock. The Fund believes
                           that a rating for the preferred stock will make it
                           easier to market the stock, which should reduce the
                           dividend rate.

Listing                    Currently, there is no public market for the Fund's
                           common stock. However, the Fund plans to apply to
                           list the Fund's shares of common stock on the New
                           York Stock Exchange or another national securities
                           exchange under the symbol "MUI."

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 daily net assets (including any proceeds from
                           the issuance of preferred stock), plus the proceeds
                           of any outstanding borrowings used for leverage. The
                           Investment Adviser has contractually agreed to waive
                           a portion of its fee during the first seven years of
                           the Fund's operations ending July , 2010, as follows:

                                                              a percentage of
                                                               average daily
                                                                net assets)
                                                              ---------------

Dividends                  The Fund intends to distribute dividends from its net
and Distributions          investment income monthly, and net realized capital
                           gains, if any, at least annually. The Fund expects
                           that it will commence paying dividends within 90 days
                           of the date of this prospectus. Once the Fund issues
                           preferred stock, the monthly dividends to common
                           stockholders will consist of net investment income
                           that remains after the Fund pays dividends on the
                           preferred stock. Currently, in order to maintain a
                           more stable level of monthly dividend distributions
                           to common stockholders, the Fund intends to pay out
                           less than all of its net investment income or pay out
                           accumulated undistributed income in addition to
                           current net investment income. The Fund will
                           distribute net capital gains, if any, at least
                           annually to common stockholders and, after it issues
                           the preferred stock, on a pro rata basis to common
                           and preferred stockholders. The Fund may not declare
                           any cash dividend or other distribution on its common
                           stock unless the preferred stock has asset coverage
                           of at least 200%. If the Fund issues preferred stock
                           representing 35% of its total capital, the preferred
                           stock's asset coverage will be approximately 286%. If
                           the Fund's ability to make distributions on its
                           common stock is limited, the Fund may not be able to
                           qualify for taxation as a regulated investment
                           company. This would have adverse tax consequences for
                           stockholders.

Yield Considerations       The yield on the Fund's common stock will vary from
                           period to period depending on factors including, but
                           not limited to, the length of the initial investment
                           period, market conditions, the timing of the Fund's
                           investment in portfolio securities, the securities
                           comprising the Fund's portfolio, the ability of the
                           issuers of the portfolio securities to pay interest
                           on such securities, changes in tax exempt interest
                           rates (which may not change to the same extent or in
                           the same direction as taxable rates) including
                           changes in the relationship between short term rates
                           and long term rates, the amount and timing of the
                           issuance of the Fund's preferred stock, the effects
                           of preferred stock leverage on the common stock
                           discussed above under "Use of Leverage by the Fund,"
                           the timing of the investment of preferred stock
                           proceeds in portfolio securities, the Fund's net
                           assets and its operating expenses. Consequently, the
                           Fund cannot guarantee any particular yield on its

                     RISK FACTORS AND SPECIAL CONSIDERATIONS

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

      Liquidity and Market Price of Shares. The Fund is newly organized and has
no operating history or history of public trading.

      Shares of closed-end funds that trade in a secondary market frequently
trade at a market price that is below their net asset value. This is commonly
referred to as "trading at a discount." The risk may be greater for investors
expecting to sell their shares in a relatively short period after completion of
the public offering. Accordingly, the Fund is designed primarily for long term
investors and should not be considered a vehicle for trading purposes. Net asset
value will be reduced following the offering by the underwriting discount and
the amount of offering expenses paid by the Fund.

      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 market
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 that 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 longer term securities
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 will decline in value. Credit risk is the risk that the issuer will be
unable to pay the interest or principal when due. The degree of credit risk
depends on both the financial condition of the issuer and the terms of the
obligation.

      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.

      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 Standard & Poor's, Moody's
Investors Service, Inc. or Fitch Ratings, 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 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
--------------------------------------------------------------------------------


                                       11


--------------------------------------------------------------------------------
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.

      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.


      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.


      Leverage. The Fund currently plans to issue preferred stock within
approximately three months after the completion of this offering. Under normal
market conditions it is anticipated that the preferred stock will represent
approximately 35% of the Fund's capital, including capital raised by issuing the
preferred stock. There can be no assurance, however, that preferred stock will
actually be issued, or if issued what percentage of the Fund's capital it will
represent. Leverage creates certain risks for common stockholders, including the
greater likelihood of higher volatility of the Fund's yield, the net asset value
and the market price of the common stock. Leverage also creates the risk that
the yield or return on shares of the Fund's common stock will be reduced or
eliminated to the extent the dividends paid on preferred stock and other
expenses of the preferred stock exceed the yield or return earned by the Fund on
its investments. Since both the cost of issuing the preferred stock and any
decline in the value of the Fund's portfolio investments (including investments
purchased with the proceeds of the preferred stock) will be borne entirely by
the holders of common stock. The effect of leverage in a declining market would
result in a greater decrease in the Fund's net asset value, and possibly the
market price of the common stock, than if the Fund was not leveraged. If the
Fund is liquidated, preferred stockholders will be entitled to receive
liquidating distributions before any distribution is made to common
stockholders.

      Sector Risk. The Fund may invest 25% or more of its total assets in tax
exempt securities of issuers in the industries comprising the same economic
sector, such as hospitals or life care facilities and transportation-related
issuers. However, the Fund will not invest 25% or more of its total assets in
any one of the industries comprising an economic sector. In addition, a
substantial part of the Fund's portfolio may be comprised of securities credit
enhanced by banks, insurance companies or companies with similar
characteristics. Emphasis on these sectors may subject the Fund to certain
risks.

      Rating Agencies. The Fund may be subject to guidelines of one or more
nationally recognized statistical ratings organizations 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.

      Liquidity of Investments. Certain Municipal Bonds in which the Fund
invests may lack an established secondary trading market or are 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 enhance 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 securities, options, futures, options on
futures, interest rate transactions, credit default swaps, and the use of short
sales. Such strategies
--------------------------------------------------------------------------------


                                       12


--------------------------------------------------------------------------------
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 inverse
securities, credit default swaps and short sales may provide investment leverage
to the Fund's portfolio and result in many of the same risks of leverage to the
holders of the Fund's common stock as discussed above under "Leverage." The Fund
is not required to use derivatives or other portfolio strategies to seek to
enhance return or to seek to hedge its portfolio and may not 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 enhance 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.

      Derivatives Risk. 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 hedging purposes or to seek to
enhance its return, such as options, futures contracts and swap agreements, and
may engage in short sales. 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. 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, the risk of
ambiguous documentation and management risk. They also involve the risk of
mispricing or improper valuation and 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. The use of derivatives also may increase the amount
of taxes payable by stockholders. 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.

      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.

      Suitability. The economic benefit of an investment in the Fund depends
upon many factors beyond the control of the Fund, the Investment Adviser and its
affiliates. Because of its emphasis on intermediate duration Municipal Bonds,
the Fund should be considered a vehicle for diversification and not as a
balanced investment program. The suitability for any particular investor of a
purchase of shares of the Fund will depend upon, among other things, such
investor's investment objectives and such investor's ability to accept the risks
of investing in such securities, including the loss of principal.

      Market Disruption. The terrorist attacks in the United States on September
11, 2001 have had a disruptive effect on the securities markets, some of which
were closed for a four-day period. These terrorist attacks and related events,
including recent U.S. military actions overseas, 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 impact
interest rates, auctions, secondary trading, ratings, credit risk, inflation and
other factors relating to the Fund's common stock. 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 these
events and other market disruptions will not have other material and adverse
implications for the non-investment grade securities markets.

----------

(a)   The Investment Adviser has agreed to pay all of the Fund's organizational
      expenses. Offering costs will be paid by the Fund up to $.03 per share.
      The Investment Adviser or an affiliate has agreed to pay the amount by
      which the offering costs (other than the sales load and the $.005 per
      share partial reimbursement of expenses to the underwriters) exceeds $.03
      per share of common stock (0.20% of the offering price). To the extent
      that the offering costs do not exceed $.03 per share of common stock, the
      Fund will pay the underwriters up to $.005 per share of common stock as a
      partial reimbursement of expenses incurred in connection with the
      offering. However, in no event will the Fund pay offering costs (other
      than the sales load, but including the partial reimbursement to the
      underwriters) in excess of $.03 per share of common stock. The offering
      costs to be paid by the Fund are not included in the annual expenses shown
      in the table. Offering costs borne by common stockholders will result in a
      reduction of capital of the Fund attributable to common stock. If the Fund
      offers preferred stock in an amount equal to approximately 35% of the
      Fund's capital, the costs of that offering, estimated to be approximately
      1.22% of the total dollar amount of the preferred stock offering, will be
      effectively borne by the common stockholders and result in a reduction of
      the net asset value of the shares of common stock. These preferred stock
      offering costs are estimated to be approximately $.10 per share of common
      stock (0.67% of the offering price).
(b)   See "Investment Advisory and Management Arrangements" -- page 39.
(c)   Assumes leverage by issuing preferred stock in an amount equal to
      approximately 35% of the Fund's capital at a dividend rate of 0.80%. If
      the Fund does not use leverage, it is estimated that, as a percentage of
      net assets attributable to common stock, the Investment Advisory Fee would
      be 0.55%, Interest Payments on Borrowed Funds would be None, Other
      Expenses would be 0.16%, Total Annual Expenses would be 0.71%, Fee and
      Expense Reimbursement would be 0.15% and Total Net Annual Expenses would
      be 0.56%.
(d)   The Investment Adviser has contractually agreed to waive its fee in the
      amount of 0.15% of average daily net assets for the first five full years
      of the Fund's operations, 0.10% of average daily net assets for year six
      and 0.05% of average daily net assets for year seven. The Total Net Annual
      Expenses reflect expenses estimated for the first fiscal year restated to
      reflect this agreement.

An investor would pay the following

$45, estimated offering expenses of this
offering of $1.90 and the estimated
preferred stock offering costs assuming
the Fund offers preferred stock in an
amount equal to approximately 35% of the
Fund's capital (after issuance) of
$6.70) on a $1,000 investment, assuming
total annual expenses of 0.93% for years
1-5, 1.01% for year 6, 1.08% for year 7

annual return throughout the periods .......  $63       $82      $102     $173

      The Fee Table is intended to assist investors in understanding the costs
and expenses that a stockholder in the Fund will bear directly or indirectly.
The expenses set forth under "Other Expenses" are based on estimated amounts
through the end of the Fund's first fiscal year and assume that the Fund issues
approximately 13,400,000 shares of common stock. If the Fund issues fewer shares
of common stock, all other things being equal, these expenses would increase.
The Example set forth above assumes reinvestment of all dividends and
distributions and uses a 5% annual rate of return as mandated by the Securities
and Exchange Commission (the "Commission") regulations. The Example should not
be considered a representation of future expenses or annual rates of return, and
actual expenses or annual rates of return may be more or less than those assumed
for purposes of the Example.

                                    THE FUND

      Muni Intermediate Duration Fund, Inc. (the "Fund") is a newly organized,
non-diversified, closed-end fund. The Fund was incorporated under the laws of
the State of Maryland on May 15, 2003, and has registered under the Investment
Company Act of 1940, as amended (the "1940 Act"). The Fund's principal office is
located at 800 Scudders Mill Road, Plainsboro, New Jersey 08536, and its
telephone number is (609) 282-2800.

      The Fund is organized as a closed-end investment company. Closed-end
investment companies differ from open-end investment companies (commonly
referred to as mutual funds) in that closed-end investment companies do not
redeem their securities at the option of the stockholder, whereas open-end
companies issue securities redeemable at net asset value at any time at the
option of the stockholder and typically engage in a continuous offering of their
shares. Accordingly, open-end investment companies are subject to continuous
asset in-flows and out-flows that can complicate portfolio management. However,
shares of closed-end investment companies frequently trade at a discount to net
asset value. They may also, at times, trade at a premium to net asset value. The
risk that shares will trade at a discount may be greater for investors expecting
to sell their shares in a relatively short period after completion of the public
offering.

      The Board of Directors of the Fund may at any time consider a merger,
consolidation or other form of reorganization of the Fund with one or more other
investment companies advised by the Fund's Investment Adviser with similar
investment objectives and policies as the Fund. Any such merger, consolidation
or other form of reorganization would require the prior approval of the Board of
Directors and the stockholders of the Fund. See "Description of Capital
Stock--Certain Provisions of the Charter and By-laws."

                                 USE OF PROCEEDS


      The net proceeds of this offering will be approximately $      million (or
approximately $           million assuming the underwriters exercise the
overallotment option in full) after payment of offering expenses estimated to be
approximately $       million and the deduction of the underwriting discount.
 To the extent that the Fund's offering costs otherwise do not exceed $.03 per
share of common stock, the Fund has agreed to pay the underwriters up to $.005
per share of common stock as a partial reimbursement of expenses incurred in
connection with the offering. However, in no event will the Fund pay offering
costs (other than the underwriting discount, but including the partial
reimbursement to the underwriters) in excess of $.03 per share of common stock.
The Investment Adviser or an affiliate will pay the amount by which the offering
costs (other than the underwriting discount and the $.005 per share partial
reimbursement of expenses to the underwriters) exceeds $.03 per share of common
stock. The Investment Adviser has agreed to pay all the Fund's organizational
expenses.


      The net proceeds of the offering will be invested in accordance with the
Fund's investment objective and policies within approximately three months after
completion of the offering of common stock, depending on market conditions and
the availability of appropriate securities. Pending such investment, it is
anticipated that the proceeds will be invested in short term, tax exempt
securities. See "Investment Objective and Policies."

                        INVESTMENT OBJECTIVE AND POLICIES

      The Fund's investment objective is to provide stockholders with high
current income exempt from Federal income taxes. The Fund seeks to achieve its
objective by investing at least 80% of its net assets (including assets acquired
from the sale of preferred stock), plus the amount 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 exempt from
Federal income tax ("Municipal Bonds"). The Fund's investment objective and its
policy of investing at least 80% of its net assets (including assets acquired
from the


                                       15


sale of preferred stock), plus the amount of any outstanding 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). Under normal market conditions, and
after the initial investment period following this offering (expected to be
approximately three months), the Fund will invest at least 80% of its net assets
(including assets acquired from the sale of preferred stock), plus the amount of
any borrowings for investment purposes, in Municipal Bonds with an
option-adjusted duration, as calculated by Fund Asset Management, L.P. (the
"Investment Adviser"), of three to ten years. This is a non-fundamental policy
and may be changed by the Fund's Board of Directors provided that stockholders
are provided with at least 60 days' prior notice of any change as required by
the 1940 Act. The Fund expects to maintain, under normal market conditions, a
dollar-weighted average portfolio duration of three to ten years. There is no
limit on the remaining maturity of each individual Municipal Bond investment by
the Fund. There can be no assurance that the Fund's investment objective will be
realized.

      Under normal market conditions, the Fund expects to invest at least 75% of
its total assets in 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). If unrated, such securities will possess creditworthiness
comparable, in the opinion of the Investment Adviser, to other obligations in
which the Fund may invest. Securities rated in the lowest investment grade
category may be considered to have speculative characteristics.

      The Fund 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. See
"Description of Municipal Bonds --`High Yield' or `Junk' Bonds." The Fund does
not intend to purchase debt securities that are in default or which the
Investment Adviser believes will soon be in default.

      The Fund may invest 25% or more of its total assets in tax exempt
securities of issuers in the industries comprising the same economic sector,
such as hospitals or life care facilities and transportation-related issuers.
However, the Fund will not invest 25% or more of its total assets in any one of
the industries comprising an economic sector. In addition, a substantial part of
the Fund's portfolio may be comprised of securities credit enhanced by banks,
insurance companies or companies with similar characteristics. Emphasis on these
sectors may subject the Fund to certain risks.

      The value of bonds and other fixed income obligations may fall when
interest rates rise and rise when interest rates fall. In general, bonds and
other fixed income obligations with longer maturities will be subject to greater
volatility resulting from interest rate fluctuations than will similar
obligations with shorter maturities. Under normal market conditions, the Fund
expects to maintain a dollar-weighted average portfolio duration of three to ten
years, including after giving effect to leverage. "Duration" measures the
sensitivity of a security's price to changes in interest rates. The greater a
portfolio's duration, the greater the change in the portfolio's value in
response to changes in interest rates. The Investment Adviser increases or
reduces the Fund's portfolio duration based on its interest rate outlook. When
the Investment Adviser expects interest rates to fall, it attempts to maintain a
longer portfolio duration. When the Investment Adviser expects interest rates to
increase, it attempts to shorten the portfolio's duration. Generally, as is the
case with any investment grade fixed income obligations, Municipal Bonds with
longer maturities tend to produce higher yields. Under normal market conditions,
however, such yield-to-maturity increases tend to decline in the longer
maturities (i.e., the slope of


                                       16


the yield curve flattens). At the same time, due to their longer exposure to
interest rate risk, prices of longer term obligations are subject to greater
market fluctuations as a result of changes in interest rates. Based on the
foregoing premises, the Investment Adviser believes that the yield and price
volatility characteristics of an intermediate duration portfolio generally offer
an attractive trade-off between return and risk. There may be market conditions,
however, where an intermediate duration portfolio may be less attractive due to
the fact that the Municipal Bond yield curve changes from time to time depending
on supply and demand forces, monetary and tax policies and investor
expectations. As a result, there may be situations where investments in
individual Municipal Bonds with longer durations may be more attractive than
individual intermediate duration Municipal Bonds.

      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. These
investments will yield taxable income. From time to time, the Fund may also
realize taxable capital gains.

      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 obligations for hedging purposes and to seek to enhance return.

      Certain Municipal Bonds may be entitled to the benefits of letters of
credit or similar credit enhancements issued by financial institutions. In such
instances, the Board of Directors of the Fund and the Investment Adviser will
take into account, in assessing the quality of such bonds, both the
creditworthiness of the issuer of such bonds and the creditworthiness of the
financial institution that provides the credit enhancement.

      The Fund ordinarily does not intend to realize investment income not
exempt from Federal income tax. 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 believes such securities to be exempt from Federal income taxation
("Non-Municipal Tax Exempt Securities"). Non-Municipal Tax Exempt Securities
could include trust certificates 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 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. Interest received on certain otherwise tax
exempt securities that are classified as "private activity bonds" (in general,
bonds that benefit non-governmental entities) may be subject to a Federal
alternative minimum tax. See "Taxes." The percentage of the Fund's total assets
invested in "private activity bonds" will vary from time to time. 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.


                                       17


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 "Investment Objective and Policies
-- 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 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 to this prospectus. Obligations are included within the term
Municipal Bonds if the interest paid thereon is excluded from gross income for
Federal income tax purposes.

      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 industrial development bonds or private activity bonds, 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 industrial development bonds ("IDBs") and, for bonds issued
after August 15, 1986, private activity bonds ("PABs").

      The Fund has not established any limit on the percentage of its portfolio
that may be invested in IDBs or PABs. The Fund's common stock 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.


                                       18


      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.

      IDBs and PABs. The Fund may purchase IDBs and PABs. IDBs and 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. IDBs and 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 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


                                       19


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 received 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 counter party 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 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 "Ratings of
Municipal Bonds" for additional information regarding ratings of debt
securities. 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.


                                       20


      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 stress, 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, the net asset value of the Fund's shares will fluctuate. There
can be no assurance that the Fund's hedging transactions will be effective. The
Fund has no obligation to enter into hedging transactions and may choose not to
do so.

      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, 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


                                       21


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 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.


                                       22


      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, 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 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.


                                       23


      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.

      Restrictions on Use of Futures Transactions. Regulations of the CFTC
applicable to the Fund require that all of the Fund's futures transactions
constitute bona fide hedging transactions and that the Fund purchase and sell
futures contracts and options thereon (i) for bona fide hedging purposes, and
(ii) for non-hedging purposes, if the aggregate initial margin and premiums
required to establish positions in such contracts and options does not exceed 5%
of the liquidation value of the Fund's portfolio assets after taking into
account unrealized profits and unrealized losses on any such contracts and
options. However, the Fund may to engage in options and futures transactions for
hedging purposes or to seek to enhance the Fund's return. Margin deposits may
consist of cash or securities acceptable to the broker and the relevant contract
market.

      When the Fund purchases a futures contract, or writes a put option or
purchases a call option thereon, it will maintain an amount of cash, cash
equivalents (e.g., high grade commercial paper and daily tender adjustable
notes) or liquid securities in a segregated account with the Fund's custodian,
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 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.


                                       24


      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.

      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.


                                       25


      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 a Fund against interest rate
fluctuations or to seek to enhance 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 to use 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


                                       26


curve, beginning with a seven day floating rate index out to 30 years. The
duration of a BMA Swap is approximately equal 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 enhance 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 that may have little or no
value. 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


                                       27


exchange for an equal face amount of deliverable obligations of the reference
entity that may have little or no value. 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 segregate
with its custodian in connection with each such transaction unencumbered 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
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.


                                       28


      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 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. 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.

Short Sales

      The Fund may make short sales of securities. A short sale is a transaction
in which the Fund sells a security it does not own in anticipation that the
market price of that security will decline. The Fund may make short sales both
as a form of hedging to offset potential declines in long positions in similar
securities and in order to seek to enhance return.


                                       29


      When the Fund makes a short sale, it must borrow the security sold short
and deliver collateral to the broker-dealer through which it made the short sale
to cover its obligation to deliver the security upon conclusion of the sale. The
Fund may have to pay a fee to borrow particular securities and is often
obligated to pay over any payments received on such borrowed securities.

      The Fund's obligation to replace the borrowed security will be secured by
collateral deposited with the broker-dealer, usually cash or liquid securities
similar to those borrowed. The Fund also will be required to segregate similar
collateral with its custodian to the extent, if any, necessary so that the value
of both collateral amounts in the aggregate is at all times equal to at least
100% of the current market value of the security sold short. Depending on
arrangements made with the broker-dealer from which it borrowed the security
regarding payment over any payments received by the Fund on such security, the
Fund may not receive any payments (including interest) on its collateral
deposited with such broker-dealer.

      If the price of the security sold short increases between the time of the
short sale and the time the Fund replaces the borrowed security, the Fund will
incur a loss. Conversely, if the price declines, the Fund will realize a gain.
Any gain will be decreased, and any loss increased, by the transaction costs
described above. Although the Fund's gain is limited to the price at which it
sold the security short, its potential loss is theoretically unlimited.

      The Fund also may make short sales "against the box." These transactions
will involve either short sales of securities retained in the Fund's portfolio
or securities which it has the right to acquire without the payment of further
consideration.

Investment in Other Investment Companies

      The Fund may invest in other investment companies whose investment
objectives and policies are consistent with those of the Fund. In accordance
with the 1940 Act, the Fund may invest up to 10% of its total assets in
securities of other investment companies. In addition, under the 1940 Act the
Fund may not own more than 3% of the total outstanding voting stock of any
investment company and not more than 5% of the value of the Fund's total assets
may be invested in securities of any investment company. The Fund has received
an exemptive order from the Commission permitting it to invest in affiliated
registered money market funds and in an affiliated private investment company
without regard to such limitations, provided however, that in all cases the
Fund's aggregate investment of cash in shares of such investment companies shall
not exceed 25% of the Fund's total assets at any time. If the Fund acquires
shares in investment companies, stockholders would bear both their proportionate
share of expenses in the Fund (including management and advisory fees) and,
indirectly, the expenses of such investment companies (including management and
advisory fees).

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 1/3% 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, or for temporary, extraordinary or emergency
purposes, including the payment of dividends and the settlement of securities
transactions which otherwise might require untimely dispositions of portfolio
securities. 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. See "Risks and Special Considerations of Leverage." In addition,
borrowed funds are subject to interest costs that may offset or exceed the
return earned on the borrowed funds.


                                       30


                  RISKS AND SPECIAL CONSIDERATIONS OF LEVERAGE

Effects of Leverage


      The Fund currently intends to issue preferred stock within approximately
three months after the completion of this offering. Under current market
conditions it is anticipated that the preferred stock will represent
approximately 35% of the Fund's capital, including the capital raised by issuing
the preferred stock, or approximately 54% of the Fund's common stock equity.
There can be no assurance, however, that preferred stock will actually be issued
or if issued what percentage of the Fund's capital it will represent. Issuing
the preferred stock will result in the leveraging of the common stock. Although
the Fund's Board of Directors has not yet determined the terms of the preferred
stock offering, the Fund anticipates that the preferred stock will pay dividends
that will be adjusted over either relatively short term periods (generally 7 to
28 days) or medium term periods (up to five years). The dividend rate will be
based upon prevailing interest rates for debt obligations of comparable
maturity. The proceeds of the preferred stock offering will be invested in
accordance with the Fund's investment objective. The expenses of the preferred
stock, which will be borne by the Fund, will reduce the net asset value of the
common stock. Additionally, under certain circumstances, when the Fund is
required to allocate taxable income to holders of preferred stock, the Fund
anticipates that the terms of the preferred stock will require the Fund to make
an additional distribution to such holders in an amount approximately equal to
the tax liability resulting from such allocation (an "Additional Distribution").
Because under normal market conditions, obligations with longer maturities
produce higher yields than short term and medium term obligations, the yield
spread inherent in the difference between the short term and medium term rates
(and any Additional Distribution) paid by the Fund as dividends on the preferred
stock and the generally longer term rates received by the Fund on its portfolio
securities may provide holders of common stock with a potentially higher yield.


      The Fund also may borrow money as discussed under "Other Investment
Policies -- Borrowings."


      The use of leverage, however, involves certain risks to the holders of
common stock. For example, issuance of the preferred stock may result in higher
volatility of the Fund's yield, net asset value and in the market price of the
Fund's common stock. In addition, changes in short term, medium term and long
term rates and their relationship to each other, could negatively impact the
Fund's yield, net asset value and market price of the Fund's common stock.
Leverage will allow holders of common stock to realize a higher current yield or
return than if the Fund were not leveraged as long as the Fund, while accounting
for its costs and operating expenses, is able to earn higher income or return on
its investment portfolio than the then current dividend rate paid on (and any
Additional Distribution) the preferred stock. Similarly, since a pro rata
portion of the Fund's net realized capital gains are generally payable to
holders of common stock, the effect of leverage may be to increase the amount of
such gains distributed to holders of common stock. However, short term, medium
term and long term interest rates change from time to time, as do their
relationships to each other (i.e., the slope of the yield curve), depending upon
such factors as supply and demand forces, monetary and tax policies and investor
expectations. Changes in any or all of such factors could cause the relationship
between short term, medium term and long term rates to change (i.e., to flatten
or to invert the slope of the yield curve) so that short term and medium term
rates may substantially increase relative to the long term obligations in which
the Fund may be invested. If short term rates were to rise relative to long term
rates, the incremental yield pickup on the common stock as a result of leverage
will be reduced or eliminated completely. To the extent that the current
dividend rate (and any Additional Distribution) paid on the preferred stock
approaches the yield or return on the Fund's investment portfolio, the benefit
of leverage to holders of common stock will be decreased. If the current
dividend rate (and any Additional Distribution) paid on the preferred stock were
to exceed the yield or return on the Fund's portfolio, holders of common stock
would receive a lower yield or return than if the Fund were not leveraged. If
long term rates rise, the value of the Fund's investments (including assets
obtained from leverage) may decline. Since both the cost of



                                       31


issuing the preferred stock and any decline in the value of the Fund's
investments (including investments purchased with the proceeds from any
preferred stock offering) will be borne entirely by holders of common stock, the
effect of leverage in a declining market would result in a greater decrease in
the Fund's net asset value and possibly the market price of the common stock
than if the Fund were not leveraged. If the Fund is liquidated, holders of
preferred stock will be entitled to receive liquidating distributions before any
distribution is made to holders of common stock.

      In an extreme case, a decline in net asset value could affect the Fund's
ability to pay dividends on the common stock. Failure to make such dividend
payments could adversely affect the Fund's qualification as a regulated
investment company under the Federal tax laws. See "Taxes." However, the Fund
intends to take all measures necessary to make common stock dividend payments.
If the Fund's current investment income is ever insufficient to meet dividend
payments on either the common stock or the preferred stock, the Fund may have to
liquidate certain of its investments. In addition, the Fund will have the
authority to redeem the preferred stock for any reason and may redeem all or
part of the preferred stock under the following circumstances:

      o     if the asset coverage for the preferred stock declines below 200%,
            or

      o     in order to maintain the asset coverage guidelines established by
            the nationally recognized statistical rating organization(s)
            ("NRSRO(s)") that have rated the preferred stock.

      Redemption of the preferred stock or insufficient investment income to
make dividend payments may reduce the net asset value of the common stock and
require the Fund to liquidate a portion of its investments at a time when it may
be disadvantageous to do so.

      As discussed under "Investment Advisory and Management Arrangements,"
during periods when the Fund has preferred stock outstanding, the fees paid the
Investment Adviser for investment advisory and management services will be
higher than if the Fund did not issue preferred stock because the fees paid will
be calculated on the basis of the Fund's average daily net assets, (including
any proceeds from the issuance of preferred stock), plus the proceeds of any
outstanding borrowings used for leverage.

      Assuming the use of leverage by issuing preferred stock (paying dividends
at a rate that generally will be adjusted every 7 days) in an amount
representing approximately 35% of the Fund's capital at an annual dividend rate
of 0.80% payable on such preferred stock based on market rates as of the date of
this prospectus, the annual return that the Fund's portfolio must experience
(net of expenses) in order to cover such dividend payments would be 0.28%.

      The following table is designed to illustrate the effect on the return to
a holder of common stock of the leverage obtained by the issuance of preferred
stock representing approximately 35% of the Fund's capital, assuming
hypothetical annual returns on the Fund's portfolio of minus 10% to plus 10%. As
the table shows, leverage generally increases the return to stockholders when
portfolio return is positive and decreases the return when portfolio return is
negative. The figures appearing in the table are hypothetical and actual returns
may be greater or less than those appearing in the table.

Assumed Portfolio Return
  (net of expenses) ..........................  (10)%  (5)%  0%  5%  10%
Corresponding Common Stock Return ............  (16)%  (8)%  0%  7%  15%

      Leveraging the common stock cannot be fully achieved until preferred stock
is issued and the proceeds of such offering have been invested in accordance
with the Fund's investment objective and policies.


                                       32


Portfolio Management and Other Considerations

      If short term or medium term rates increase or other changes in market
conditions occur to the point where the Fund's leverage could adversely affect
holders of common stock as noted above (or in anticipation of such changes), the
Fund may attempt to shorten the average maturity or duration of its investment
portfolio in order to offset the negative impact of leverage. The Fund also may
attempt to reduce the degree to which it is leveraged by redeeming preferred
stock pursuant to the Fund's Articles Supplementary, which establish the rights
and preferences of the preferred stock, or otherwise by purchasing shares of
preferred stock. Purchases and redemptions of preferred stock, whether on the
open market or in negotiated transactions, are subject to limitations under the
1940 Act. In determining whether or not it is in the best interest of the Fund
and its stockholders to redeem or repurchase outstanding preferred stock, the
Board of Directors will take into account a variety of factors, including the
following:

      o     market conditions;

      o     the ratio of preferred stock to common stock; and

      o     the expenses associated with such redemption or repurchase.

      If market conditions subsequently change, the Fund may sell previously
unissued shares of preferred stock or shares of preferred stock that the Fund
had issued but later repurchased or redeemed. The Fund will incur additional
expenses in connection with the subsequent registration and sale of preferred
stock.

      The Fund intends to apply for ratings of the preferred stock from one or
more NRSRO(s). In order to obtain these ratings, the Fund may be required to
maintain portfolio holdings that meet the specified guidelines of such
organizations. These guidelines may impose asset coverage requirements that are
more stringent than those imposed by the 1940 Act. The Fund does not anticipate
that these guidelines will impede the Investment Adviser from managing the
Fund's portfolio in accordance with the Fund's investment objective and
policies. Ratings on preferred stock issued by the Fund should not be confused
with ratings on the obligations held by the Fund.

      Under the 1940 Act, the Fund is not permitted to issue shares of preferred
stock unless immediately after such issuance the net asset value of the Fund's
portfolio is at least 200% of the liquidation value of the outstanding preferred
stock (expected to equal the original purchase price of the outstanding shares
of preferred stock plus any accumulated and unpaid dividends thereon and any
accumulated and unpaid Additional Distribution). In addition, the Fund is not
permitted to declare any cash dividend or other distribution on its common stock
unless, at the time of such declaration, the net asset value of the Fund's
portfolio (determined after deducting the amount of such dividend or
distribution) is at least 200% of the liquidation value of the outstanding
preferred stock. Under the Fund's proposed capital structure, assuming the sale
of shares of preferred stock representing approximately 35% of the Fund's
capital, the net asset value of the Fund's portfolio is expected to be
approximately 286% of the liquidation value of the Fund's preferred stock. To
the extent possible, the Fund intends to purchase or redeem shares of preferred
stock from time to time to maintain coverage of preferred stock of at least
200%.

      The Fund may in the future employ new or additional investment strategies
and hedging instruments if those strategies and instruments are consistent with
the Fund's investment objective and are permissible under applicable regulations
governing the Fund.

                             INVESTMENT RESTRICTIONS

      The following are fundamental investment restrictions of the Fund and,
prior to issuance of any preferred stock, may not be changed without the
approval of the holders of a majority of the Fund's outstanding shares of common
stock (which for this purpose and under the 1940 Act means the lesser of (i) 67%
of the shares of common stock represented at a meeting at which more than 50% of
the outstanding shares of common stock are represented or (ii) more than 50% of
the outstanding shares). Subsequent to the issuance of a class of preferred


                                       33


stock, the following investment restrictions may not be changed without the
approval of a majority of the outstanding shares of common stock and of
preferred stock, voting together as a class, and the approval of a majority of
the outstanding shares of preferred stock, voting separately as a class. The
Fund may not:

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

            2. Purchase or sell real estate, commodities or commodity contracts;
      except that to the extent permitted by applicable law, the Fund may invest
      in securities directly or indirectly secured by real estate or interests
      therein or issued by entities that invest in real estate or interests
      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 (i) the Fund shall not be
      deemed to be making a loan to the extent that the Fund purchases Municipal
      Bonds or other debt instruments or enters into repurchase agreements or
      any similar instruments and (ii) the Fund may lend its portfolio
      securities in an amount not in excess of 33 1/3% of its total assets,
      taken at market value, provided that such loans shall be made in
      accordance with the guidelines set forth in this prospectus.

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

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

            a. Purchase securities of other investment companies, except to the
      extent that such purchases are permitted by applicable law. Applicable law
      currently 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 provided
      that 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 described under "Other Investment Policies."

            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. Change its policy of investing, under normal market conditions,
      at least 80% of the Fund's net assets (including assets acquired from the
      sale of preferred stock), plus the amount of any borrowings for investment
      purposes, in Municipal Bonds with an option-adjusted duration, as
      calculated by the Fund's Investment Adviser, of three to ten years, unless
      the Fund provides stockholders with at least 60 days prior written notice
      of such change.


                                       34


      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 percentage 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 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 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."

                             DIRECTORS AND OFFICERS

      The Directors of the Fund consist of five individuals, four of whom are
not "interested persons" of the Fund as defined in the 1940 Act (the
"non-interested Directors"). The Directors are responsible for the overall
supervision 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 and
Nominating Committee (the "Committee"). The principal responsibilities of the
Committee are the appointment, compensation and oversight of the Fund's
independent auditors, including resolution of disagreements regarding financial
reporting between Fund management and such auditors. The Board of the Fund has
adopted a written charter for the Committee. The Committee also reviews and
nominates candidates to serve as non-interested Directors. The Committee has
retained independent legal counsel to assist them in connection with these
duties. Since the Fund was incorporated, the Committee has held one meeting.

                 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 100 registered investment
companies and offers investment advisory services to individuals and
institutional accounts. As of April 2003, the Investment Adviser and its
affiliates, including MLIM, had a total of approximately $449 billion in
investment company and other portfolio assets under management, including
approximately $257 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 direction
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 review by the Board of Directors.

      The Fund's portfolio manager will consider analyses from various sources,
make the necessary investment decisions, and place orders for transactions
accordingly. The Investment Adviser will also be responsible for the performance
of certain management services for the Fund. The Fund will be managed by a team
of investment professionals from the Investment Adviser. The portfolio manager
primarily responsible for the Fund's day-to-day management is Robert A. DiMella,
CFA.

      Robert DiMella is a Vice President of MLIM since 1997 and has 13 years of
experience investing in Municipal Bonds.

      For its services, the Fund pays the Investment Adviser a monthly fee at
the annual rate of 0.55% of the Fund's average daily net assets plus the
proceeds of any outstanding borrowings used for leverage ("average daily net
assets" means the average daily value of the total assets of the Fund, including
the amount obtained from leverage and any 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 daily net assets is determined at the end of


                                       39


each month on the basis of the average net assets of the Fund for each day
during the month. It is understood that 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 Adviser has contractually agreed to waive a portion of its
fee during the first seven years of the Fund's operations ending July , 2010, as
follows:

                                                        Fee Waiver (as
                                                        a percentage of
                                                         average daily
                                                          net assets)
                                                        ---------------
                  Years 1 through 5 ..................       0.15%
                  Year 6 .............................       0.10%
                  Year 7 .............................       0.05%

The Investment Adviser has not agreed to waive any of its fee beyond July ,
2010.

      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 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.

      Unless earlier terminated as described below, the Investment Advisory
Agreement will remain in effect for a period of two years from the date of
execution and will remain in effect from year to year thereafter if approved
annually (a) by the Board of Directors of the Fund or by a majority of the
outstanding shares of the Fund and (b) by a majority of the Directors who are
not parties to such contract or interested persons (as defined in the 1940 Act)
of any such party. Such contract is not assignable and may be terminated without
penalty on 60 days' written notice at the option of either party thereto or by
the vote of the stockholders of the Fund.

      In connection with the Board of Director's consideration of the Investment
Advisory Agreement, the Board reviewed information derived from a number of
sources and covering a range of issues relating to, among other things,
alternatives to the Investment Advisory Agreement. The Board of Directors
considered the services to be provided to the Fund by the Investment Adviser
under the Investment Advisory Agreement, as well as other services to be
provided by the Investment Adviser and its affiliates under other agreements,
and the personnel who will provide these services. In addition to the investment
advisory services to be provided to the Fund, the Investment Adviser and its
affiliates will provide administrative services, stockholder services, oversight
of fund accounting, assistance in meeting legal and regulatory requirements, and
other services necessary for the operation of the Fund. The Fund's Board of
Directors also considered the direct and indirect benefits to the Investment
Adviser from its relationship with the Fund. The benefits considered by the
Board of Directors included not only the Investment Adviser's compensation for
investment advisory services, but also compensation paid to the Investment
Adviser or its affiliates for other non-advisory services provided to the Fund.
The Board of Directors concluded that the advisory fee was reasonable in
relation to the services to be provided by the Investment Adviser to the Fund as
well as the anticipated costs and benefits to be gained by the Investment
Adviser in providing such services.


                                       40


      In reaching its conclusion, the Board of Directors focused on the
experience, resources and strengths of the Investment Adviser and its affiliates
in managing leveraged, closed-end investment companies that invest in Municipal
Bonds. The Board of Directors, based on their experience as directors of other
investment companies managed by the Investment Adviser and its affiliates, also
focused on the quality of the compliance and administrative staff at the
Investment Adviser. In connection with its consideration of the Investment
Advisory Agreement, the Board of Directors placed significant emphasis on the
Fund's advisory fee rate and anticipated expense ratios as compared to those of
comparable leveraged, closed-end funds managed by other investment advisers
("comparable funds") investing in Municipal Bonds and similar instruments as
provided by Lipper Inc. In particular, the Board of Directors reviewed the
advisory fee rate of eleven comparable leveraged, closed-end funds with
substantially similar investment objectives and policies. The Board of Directors
noted that the Fund has the lowest contractual advisory fee rate at the
estimated asset level for the Fund's among the comparable funds. Based in part
on this fee comparison, and taking into account the quality of the various
services to be provided to the Fund by the Investment Adviser and its affiliates
discussed above, the Investment Adviser's experience in managing Municipal
Bonds, and the Board of Directors' experience with the nature and quality of
portfolio management, administrative and compliance services provided by the
Investment Adviser to other investment companies, the Fund's Board of Directors
concluded that the advisory fee rate was reasonable. The Board of Directors
considered whether there should be changes in the advisory fee rate or structure
in order to enable the Fund to participate in any economies of scale that the
Investment Adviser may experience as a result of growth in the Fund's assets.
The Fund's Board of Directors also reviewed materials supplied by counsel that
were prepared for use by the Board of Directors in fulfilling its duties under
the 1940 Act.

      Based on the information reviewed and the discussions, the Board of
Directors, including a majority of the non-interested Directors, concluded that
it was satisfied with the nature and quality of the services to be provided by
the Investment Adviser to the Fund and that the advisory fee rate was reasonable
in relation to such services. The non-interested Directors were represented by
independent counsel who assisted them in their deliberations.

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.

                             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


                                       41


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, 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 Board of
Directors will reconsider this matter from time to time.

      The Fund has received an exemptive order from the Commission permitting it
to lend portfolio securities to Merrill Lynch or its affiliates. Pursuant to
that order, the Fund also has retained an affiliated entity of the Investment
Adviser as the securities lending agent for a fee, including a fee based on a
share of the returns on investment of cash collateral. That entity may, on
behalf of the Fund, invest cash collateral received by the Fund for such loans,
among other things, in a private investment company managed by that entity or in
registered money market funds advised by the Investment Adviser or its
affiliates.

      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.


                                       42


      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 market conditions, 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 also has certain tax consequences for
stockholders.

                           DIVIDENDS AND DISTRIBUTIONS

      The Fund intends to distribute dividends from its net investment income
monthly to holders of common stock. It is expected that the Fund will commence
paying dividends to holders of common stock within approximately 90 days of the
date of this prospectus. From and after issuance of the preferred stock, monthly
dividends to holders of common stock normally will consist of net investment
income remaining after the payment of dividends (and any Additional
Distributions) on the preferred stock. The Fund currently intends either to pay
out less than the entire amount of net investment income earned in any
particular period or pay out such accumulated undistributed income in addition
to net investment income earned in other periods in order to permit the Fund to
maintain a more stable level of dividend distributions. As a result, the
dividend paid by the Fund to holders of common stock for any particular period
may be more or less than the amount of net investment income earned by the Fund
during such period. The Fund is not required to attempt to maintain a more
stable level of distributions to stockholders and may choose not to do so. For
Federal tax purposes, the Fund is required to distribute substantially all of
its net investment income for each calendar year. All net realized capital
gains, if any, will be distributed pro rata at least annually to holders of
common stock and any preferred stock. While any shares of preferred stock are
outstanding, the Fund may not declare any cash dividend or other distribution on
its common stock, unless at the time of such declaration, (i) all accumulated
preferred stock dividends, including any Additional Distribution, have been
paid, and (ii) the net asset value of the Fund's portfolio (determined after
deducting the amount of such dividend or other distribution) is at least 200% of
the liquidation value of the outstanding preferred stock (expected to equal the
original purchase price of the outstanding shares of preferred stock plus any
accumulated and unpaid dividends thereon and any accumulated but unpaid
Additional


                                       43


Distribution). If the Fund's ability to make distributions on its common stock
is limited, such limitation could under certain circumstances impair the ability
of the Fund to maintain its qualification for taxation as a regulated investment
company, which would have adverse tax consequences for stockholders. See
"Taxes."

      See "Automatic Dividend Reinvestment Plan" for information concerning the
manner in which dividends and distributions to holders of common stock may be
automatically reinvested in shares of common stock of the Fund. Dividends and
distributions may be taxable to stockholders under certain circumstances as
discussed below, whether they are reinvested in shares of the Fund or received
in cash.

      The yield on the Fund's common stock will vary from period to period
depending on factors including, but not limited to, the length of the initial
investment period, market conditions, the ability of the issuer of the portfolio
securities to pay interest on such securities, the timing of the Fund's
investment in portfolio securities, the securities comprising the Fund's
portfolio, changes in tax exempt interest rates (which may not change to the
same extent or in the same direction as taxable rates) including changes in the
relationship between short term rates and long term rates, the amount and timing
of the issuance of the Fund's preferred stock, the effects of preferred stock
leverage on the common stock discussed above under "Risks and Special
Considerations of Leverage," the timing of the investment of preferred stock
proceeds in portfolio securities, the Fund's net assets and its operating
expenses. Consequently, the Fund cannot guarantee any particular yield on its
shares and the yield for any given period is not an indication or representation
of future yields on Fund shares.

                                      TAXES

General

      The Fund intends to elect and to qualify for the special tax treatment
afforded regulated investment companies ("RICs") under 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.

      The Code requires a regulated investment company ("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 October 31
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 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 the interest on 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 excludable from gross income for Federal income tax
purposes under Code Section 103(a) and are properly designated as
exempt-interest dividends, they will be


                                       44


excludable from a stockholder's gross income for Federal income 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 or IDBs, if any, held by the Fund.

      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
are considered taxable ordinary income for Federal income tax purposes.
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 ("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. Distributions by the Fund,
whether from exempt-income, ordinary income or capital gains, are not eligible
for the dividends received deduction allowed to corporations under the Code.

      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 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 common stock normally will result in capital gain or
loss to the holders of common stock who hold their shares as capital assets.
Generally, a shareholders' gain or loss will be long-term capital gain or loss
if the shares have been held for more than one year.

      No loss will be allowed on the sale of common stock if the stockholder
purchases other common stock of the Fund (whether through reinvestment or
distributions or otherwise) or the stockholder acquires or enters into a
contract or an option to acquire shares that are substantially identical to
common stock of the Fund within a period of 61 days beginning 30 days before and
ending 30 days after such sale or exchange. If disallowed, the loss will be
reflected in an adjustment to the basis of the shares acquired. 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 common stock, you may not be
permitted to deduct the interest on that loan. Under Federal income tax rules,
the Fund's common stock may be treated as having been bought with borrowed money
even if the purchase of the Fund's common stock cannot be traced directly to
borrowed money. Stockholders should consult their own tax advisers regarding the
impact of an investment in common stock upon the deductibility of interest
payable by the stockholder.

      Prior to purchasing the Fund's common stock, an investor should carefully
consider the impact of dividends which are expected to be or have been declared,
but not paid. Any dividend declared shortly after a purchase of the Fund's
common stock prior to the record date will have the effect of reducing the per
share net asset value by the per share amount of the dividend. If the Fund pays
a dividend in January that was declared in the previous


                                       45


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.

      The Internal Revenue Service ("Service") 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.
Consequently, when common stock and one or more series of preferred stock are
outstanding, the Fund intends to designate distributions made to the classes as
consisting of particular types of income in accordance with each class's
proportionate share of such income. Thus, the Fund will designate dividends paid
as exempt-interest dividends in a manner that allocates such dividends among the
holders of common stock and each series of preferred stock in proportion to the
total dividends paid to each class during the taxable year, or otherwise as
required by applicable law. Capital gain dividends will similarly be allocated
among the classes in proportion to the total dividends paid to each class during
the taxable year, or otherwise as required by applicable law. When capital gain
or other taxable income is allocated to holders of preferred stock pursuant to
the allocation rules described above, the terms of the preferred stock may
require the Fund to make an additional distribution to or otherwise compensate
such holders for the tax liability resulting from such allocation.

      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 certain "private activity bonds" issued
after August 7, 1986. Private activity bonds 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 "private activity bonds" and will report
to stockholders within 60 days after calendar year-end the portion of its
dividends declared during the year that 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 swaps. The Federal income tax rules
governing the taxation of interest rate swaps are not entirely clear and may
require the Fund to treat payments received under such arrangements as ordinary
income and to amortize payments made under certain circumstances. Additionally,
because the treatment of swaps under the RIC qualification rules is not clear,
the Fund will monitor its activity in this regard in order to maintain its
qualification as a RIC. 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.


                                       46


      Certain transactions of 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 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.

      If at any time when shares of preferred stock 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 "Dividends and Distributions." This may prevent the
Fund from distributing at least 90% of its net investment 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 redeem shares of preferred stock 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. 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.
Some types of preferred stock that the Fund contemplates issuing 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 dividend. If the Fund ultimately relies solely
on a legal opinion when it issues such preferred stock, there is no assurance
that the Service would agree that dividends on the preferred stock are not
preferential. If the Service successfully disallowed the dividends paid
deduction for dividends on the preferred stock, the Fund could be disqualified
as a RIC. 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 Federal alternative minimum tax.

      The value of shares acquired pursuant to the Fund's dividend reinvestment
plan will generally be excluded from gross income to the extent that the cash
amount reinvested would be excluded from gross income. If, when the Fund's
shares are trading at a premium over net asset value, the Fund issues shares
pursuant to the dividend reinvestment plan that have a greater fair market value
than the amount of cash reinvested, it is possible that all or a portion of such
discount (which may not exceed 5% of the fair market value of the Fund's shares)
could be viewed as a taxable distribution. If the discount is viewed as a
taxable distribution, it is also possible that the taxable character of this
discount would be allocable to all of the stockholders, including stockholders
who do not participate in the dividend reinvestment plan. Thus, stockholders who
do not participate in the dividend reinvestment plan, as well as dividend
reinvestment plan participants, might be required to report as ordinary income a
portion of their distributions equal to their allocable share of the discount.

      Under certain Code provisions, some taxpayers may be subject to a
withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
stockholders subject to backup withholding are those for whom no certified
taxpayer identification number is on


                                       47


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.

      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.

                      AUTOMATIC DIVIDEND REINVESTMENT PLAN

      Pursuant to the Fund's Automatic Dividend Reinvestment Plan (the "Plan"),
unless a stockholder is ineligible or elects otherwise, all dividend and capital
gains distributions are automatically reinvested by EquiServe, L.P.
("EquiServe"), as agent for stockholders in administering the Plan (the "Plan
Agent"), in additional shares of common stock of the Fund. Stockholders whose
shares are held in the name of a broker or nominee should contact such broker or
nominee to confirm that they are eligible to participate in the Plan.
Stockholders who are ineligible or who elect not to participate in the Plan will
receive all dividends and distributions in cash paid by check mailed directly to
the stockholder of record (or, if the shares are held in street or other nominee
name, then to such nominee) by EquiServe, as dividend paying agent. Such
stockholders may elect not to participate in the Plan and to receive all
distributions of dividends and capital gains in cash by sending written
instructions to EquiServe, as dividend paying agent, at the address set forth
below. Participation in the Plan is completely voluntary and may be terminated
or resumed at any time without penalty by written notice if received by the Plan
Agent not less than ten days prior to any dividend record date; otherwise, such
termination will be effective with respect to any subsequently declared dividend
or capital gains distribution.

      Whenever the Fund declares an ordinary income dividend or a capital gain
dividend (collectively referred to as "dividends") payable either in shares or
in cash, non-participants in the Plan will receive cash, and participants in the
Plan will receive the equivalent in shares of common stock. The shares are
acquired by the


                                       48


Plan Agent for the participant's account, depending upon the circumstances
described below, either (i) through receipt of additional unissued but
authorized shares of common stock from the Fund ("newly issued shares") or (ii)
by purchase of outstanding shares of common stock on the open market
("open-market purchases") on the NYSE or elsewhere. If, on the dividend payment
date, the net asset value per share of the common stock is equal to or less than
the market price per share of the common stock plus estimated brokerage
commissions (such condition being referred to herein as "market premium"), the
Plan Agent will invest the dividend amount in newly issued shares on behalf of
the participant. The number of newly issued shares of common stock to be
credited to the participant's account will be determined by dividing the dollar
amount of the dividend by the net asset value per share on the date the shares
are issued, provided that the maximum discount from the then current market
price per share on the date of issuance may not exceed 5%. If on the dividend
payment date the net asset value per share is greater than the market value
(such condition being referred to herein as "market discount"), the Plan Agent
will invest the dividend amount in shares acquired on behalf of the participant
in open-market purchases.

      In the event of a market discount on the dividend payment date, the Plan
Agent has until the last business day before the next date on which the shares
trade on an "ex-dividend" basis or in no event more than 30 days after the
dividend payment date (the "last purchase date") to invest the dividend amount
in shares acquired in open-market purchases. It is contemplated that the Fund
will pay monthly income dividends. Therefore, the period during which
open-market purchases can be made will exist only from the payment date on the
dividend through the date before the next "ex-dividend" date, which typically
will be approximately ten days. If, before the Plan Agent has completed its
open-market purchases, the market price of a share of common stock exceeds the
net asset value per share, the average per share purchase price paid by the Plan
Agent may exceed the net asset value of the Fund's shares, resulting in the
acquisition of fewer shares than if the dividend had been paid in newly issued
shares on the dividend payment date. Because of the foregoing difficulty with
respect to open-market purchases, the Plan provides that if the Plan Agent is
unable to invest the full dividend amount in open-market purchases during the
purchase period or if the market discount shifts to a market premium during the
purchase period, the Plan Agent will cease making open-market purchases and will
invest the uninvested portion of the dividend amount in newly issued shares at
the close of business on the last purchase date.

      The Plan Agent maintains all stockholders' accounts in the Plan and
furnishes written confirmation of all transactions in the account, including
information needed by stockholders for tax records. Shares in the account of
each Plan participant will be held by the Plan Agent in non-certificated form in
the name of the participant, and each stockholder's proxy will include those
shares purchased or received pursuant to the Plan. The Plan Agent will forward
all proxy solicitation materials to participants and vote proxies for shares
held pursuant to the Plan in accordance with the instructions of the
participants.

      In the case of stockholders such as banks, brokers or nominees which hold
shares for others who are the beneficial owners, the Plan Agent will administer
the Plan on the basis of the number of shares certified from time to time by the
record stockholders as representing the total amount registered in the record
stockholder's name and held for the account of beneficial owners who are to
participate in the Plan.

      There will be no brokerage charges with respect to shares issued directly
by the Fund as a result of dividends or capital gains distributions payable
either in shares or in cash. However, each participant will pay a pro rata share
of brokerage commissions incurred with respect to the Plan Agent's open-market
purchases in connection with the reinvestment of dividends.

      The automatic reinvestment of dividends and distributions will not relieve
participants of any Federal, state or local income tax that may be payable (or
required to be withheld) on such dividends. See "Taxes."


                                       49


      Stockholders participating in the Plan may receive benefits not available
to stockholders not participating in the Plan. If the market price plus
commissions of the Fund's shares is higher than the net asset value,
participants in the Plan will receive shares of the Fund at less than they could
otherwise purchase them and will have shares with a cash value greater than the
value of any cash distribution they would have received on their shares. If the
market price plus commissions is below the net asset value, participants receive
distributions of shares with a net asset value greater than the value of any
cash distribution they would have received on their shares. However, there may
be insufficient shares available in the market to make distributions in shares
at prices below the net asset value. Also, since the Fund does not redeem its
shares, the price on resale may be more or less than the net asset value.

      Experience under the Plan may indicate that changes are desirable.
Accordingly, the Fund reserves the right to amend or terminate the Plan. There
is no direct service charge to participants in the Plan; however, the Fund
reserves the right to amend the Plan to include a service charge payable by the
participants.

      All correspondence concerning the Plan should be directed to the Plan
Agent at 150 Royall Street, Canton, Massachusetts 02021.

                          MUTUAL FUND INVESTMENT OPTION

      Purchasers of shares of common stock of the Fund in this offering will
have an investment option consisting of the right to reinvest the net proceeds
from a sale of such shares (the "Original Shares") in Class A initial sales
charge shares of certain FAM/MLIM advised open-end mutual funds ("Eligible Class
A Shares") at their net asset value, without the imposition of the initial sales
charge, if the conditions set forth below are satisfied. First, the sale of Fund
shares must be made through Merrill Lynch, or another broker-dealer or other
financial intermediary ("Selected Dealer") that maintains an arrangement with
the open-end fund's distributor for the purchase of the Eligible Class A Shares
and the net proceeds therefrom must be immediately reinvested in Eligible Class
A Shares. Second, the Fund shares must either have been acquired in the Fund's
initial public offering or represent dividends paid on shares of common stock
acquired in such offering. Third, the Fund shares must have been continuously
maintained in a securities account held at Merrill Lynch or another Selected
Dealer. Fourth, there must be a minimum purchase of $250 to be eligible for the
investment option. The Eligible Class A Shares may be redeemed at any time at
the next determined net asset value, subject in certain cases to a redemption
fee.

                                 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.

      The Municipal Bonds in which the Fund invests are traded primarily in the
over-the-counter markets. In determining net asset value, the Fund uses the
valuations of portfolio securities furnished by a pricing service approved by
the Board of Directors. The pricing service typically values portfolio
securities at the bid price or the yield equivalent when quotations are readily
available. Municipal Bonds for which quotations are not readily available are
valued at fair market value on a consistent basis as determined by the pricing
service using a matrix


                                       50


system to determine valuations. The procedures of the pricing service and its
valuations are reviewed by the officers of the Fund under the general
supervision of the Board of Directors. The Board of Directors has determined in
good faith that the use of a pricing service is a fair method of determining the
valuation of portfolio securities. Positions in futures contracts and interest
rate swaps are valued at closing prices for such contracts established by the
exchange or dealer market on which they are traded, or if market quotations are
not readily available, are valued at fair value on a consistent basis using
methods approved in good faith by the Board of 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.

      The value of interest rate swaps, caps and floors is determined in
accordance with a formula and then confirmed periodically by obtaining a bank
quotation. Positions in options are valued at the last sale price on the market
where any such option is principally traded. Positions in futures contracts are
valued at closing prices for such contracts established by the exchange on which
they are traded. Obligations with remaining maturities of 60 days or less are
valued at amortized cost unless this method no longer produces fair valuations.
Repurchase agreements are valued at cost plus accrued interest.

                          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 are 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, 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. The Fund may reclassify an
amount of unissued common stock as preferred stock and at that time offer shares
of preferred stock. See "Risks and Special Considerations of Leverage."

Common Stock

      Shares of common stock, when issued and outstanding, will be fully paid
and non-assessable. Stockholders are entitled to share pro rata in the net
assets of the Fund available for distribution to stockholders upon liquidation
of the Fund. Stockholders are entitled to one vote for each share held.

      In the event that the Fund issues preferred stock and so long as any
shares of the Fund's preferred stock are outstanding, 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
"Risks and Special Considerations of Leverage."

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


                                       51


      The Investment Adviser provided the initial capital for the Fund by
purchasing shares of common stock of the Fund for $ . As of the date of this
prospectus, the Investment Adviser owned 100% of the outstanding shares of
common stock of the Fund. The Investment Adviser may be deemed to control the
Fund until such time as it owns less than 25% of the outstanding shares of the
Fund.

Preferred Stock

      It is anticipated that the Fund's shares of preferred stock will be issued
in one or more series, with rights as determined by the Board of Directors, by
action of the Board of Directors without the approval of the holders of common
stock. Under the 1940 Act, the Fund is permitted to have outstanding more than
one series of preferred stock so long as no single series has a priority over
another series as to the distribution of assets of the Fund or the payment of
dividends. Holders of common stock have no preemptive right to purchase any
shares of preferred stock that might be issued. It is anticipated that the net
asset value per share of the preferred stock will equal its original purchase
price per share plus accumulated dividends per share.

      The Fund's Board of Directors has declared its intention to authorize an
offering of shares of preferred stock (representing approximately 35% of the
Fund's capital immediately after the issuance of such preferred stock) within
approximately three months after completion of the offering of common stock,
subject to market conditions and to the Board's continuing to believe that
leveraging the Fund's capital structure through the issuance of preferred stock
is likely to achieve the benefits to the holders of common stock described in
the prospectus. Although the terms of the preferred stock, including its
dividend rate, voting rights, liquidation preference and redemption provisions
will be determined by the Board of Directors (subject to applicable law and the
Fund's Charter), the initial series of preferred stock will be structured to
carry either a relatively short term dividend rate, in which case periodic
redetermination of the dividend rate will be made at relatively short intervals
(generally 7 or 28 days), or a medium term dividend rate, in which case periodic
redetermination of the dividend rate will be made at intervals of up to five
years. In either case, such redetermination of the dividend rate will be made
through an auction or remarketing procedure. The Board also has indicated that
it is likely that the liquidation preference, voting rights and redemption
provisions of the preferred stock will be as stated below.

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

      Voting Rights. Except as otherwise indicated in this prospectus and except
as otherwise required by applicable law, holders of shares of preferred stock
will have equal voting rights with holders of shares of common stock (one vote
per share) and will vote together with holders of common stock as a single
class.

      In connection with the election of the Fund's Directors, holders of shares
of preferred stock, voting as a separate class, will be entitled to elect two of
the Fund's Directors, and the remaining Directors will be elected by all holders
of capital stock, voting as a single class. So long as any preferred stock is
outstanding, the Fund will have not less than five Directors. If at any time
dividends on shares of the Fund's preferred stock shall be


                                       52


unpaid in an amount equal to two full years' dividends thereon, the holders of
all outstanding shares of preferred stock, voting as a separate class, will be
entitled to elect a majority of the Fund's directors until all dividends in
default have been paid or declared and set apart for payment.

      The affirmative vote of the holders of a majority of the outstanding
shares of the preferred stock, voting as a separate class, will be required to
(i) authorize, create or issue any class or series of stock ranking prior to any
series of preferred stock with respect to payment of dividends or the
distribution of assets on liquidation 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 preferred stock.

      Redemption Provisions. It is anticipated that shares of preferred stock
will generally be redeemable at the option of the Fund at a price equal to their
liquidation preference plus accumulated but unpaid dividends to the date of
redemption plus, under certain circumstances, a redemption premium. Shares of
preferred stock will also be subject to mandatory redemption at a price equal to
their liquidation preference plus accumulated but unpaid dividends to the date
of redemption upon the occurrence of certain specified events, such as the
failure of the Fund to maintain asset coverage requirements for the preferred
stock specified by the rating agencies that issue ratings on the preferred
stock.

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 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 but only by vote of the holders of at least 66 2/3% of the shares
entitled to vote in an election to fill that directorship.

      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. Following any issuance of preferred stock
by the Fund, it is anticipated that the approval, adoption or authorization of
the foregoing also would require the favorable vote of a majority of the Fund's
shares of preferred stock 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
any 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 two-thirds of the total number of Directors fixed in
accordance with the By-laws), and,


                                       53


assuming preferred stock is issued, the affirmative vote of a majority of
outstanding shares of preferred stock of the Fund, 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. All redemptions will be made in cash. 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 changes in
certain of the Fund's investment policies and restrictions, such as those
relating to 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.

      The Board of Directors has determined that the 66 2/3% 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 Commission for the full
text of these provisions.

      The Fund's By-laws generally require that advance notice be given to the
Fund in the event a stockholder desires to nominate a person for election to the
Board of Directors or to transact any other business at an annual meeting of
stockholders. With respect to an annual meeting following the first annual
meeting of stockholders, notice of any such nomination or business must be
delivered to or received at the principal executive offices of the Fund not less
than 60 calendar days nor more than 90 calendar days prior to the anniversary
date of the prior year's annual meeting (subject to certain exceptions). In the
case of the first annual meeting of stockholders, the notice must be given no
later than the tenth calendar day following the day upon which public disclosure
of the date of the meeting is first made. Any notice by a stockholder must be
accompanied by certain information as provided in the By-laws.

                                  UNDERWRITING

      The Fund intends to offer the shares through the underwriters. Merrill
Lynch, Pierce, Fenner & Smith Incorporated is acting as representative of the
underwriters named below. Subject to the terms and conditions contained in a
purchase agreement between the Fund and the Investment Adviser and the
underwriters, the Fund has agreed to sell to the underwriters, and each
underwriter listed below severally has agreed to purchase from the Fund, the
number of shares listed opposite their names below.

                                                                     Number of
                                Underwriter                            Shares
                                -----------                          ---------

                   Merrill Lynch, Pierce, Fenner & Smith
                               Incorporated ....................
                                                                   ------------



                               Total ...........................
                                                                   ============


      The underwriters have agreed to purchase all of the shares sold pursuant
to the purchase agreement if any of these shares are purchased. If an
underwriter defaults, the purchase agreement provides that the purchase
commitments of the nondefaulting underwriters may be increased or the purchase
agreement may be terminated.

      The Fund and the Investment Adviser have agreed to indemnify the
underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended, or to contribute to payments the
underwriters may be required to make in respect of those liabilities.

      The underwriters are offering the shares, subject to prior sale, when, as
and if issued to and accepted by them, subject to approval of legal matters by
their counsel, including the validity of the shares, and other conditions
contained in the purchase agreement, such as the receipt by the underwriters of
officer's certificates and legal opinions. The underwriters reserve the right to
withdraw, cancel or modify offers to the public and to reject orders in whole or
in part.

Commissions and Discounts

      The underwriters have advised the Fund that they propose initially to
offer the shares 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 $        per share. The underwriters may allow, and the dealers may
reallow, a discount not in excess of $      per share to other dealers. There is
a sales charge or underwriting discount of $.675 per share, which is equal to
4.5% of the initial public offering price per share. After the initial public
offering, the public offering price, concession and discount may be changed.
Investors must pay for the shares of common stock purchased in the offering on
or before August , 2003.


                                       55


      The following table shows the public offering price, underwriting discount
and proceeds before expenses to the Fund. The information assumes either no
exercise or full exercise by the underwriters of their overallotment option.

                                         Per Share   Without Option  With Option
                                         ---------   --------------  -----------
Public offering price .................    $15.00           $             $

Underwriting discount .................     $.675           $             $

Proceeds, before expenses,
  to the Fund .........................   $14.325           $             $


      The expenses of the offering, excluding underwriting discount, are
estimated at $       and are payable by the Fund. To the extent that the Fund's
offering costs do not exceed $.03 per share of common stock, the Fund has agreed
to pay the underwriters up to $.005 per share of common stock as a partial
reimbursement of expenses incurred in connection with the offering. However, in
no event will the Fund pay offering costs (other than the underwriting discount,
but including the partial reimbursement to the underwriters) in excess of $.03
per share of common stock. The Investment Adviser or an affiliate will pay the
amount by which the offering costs (other than the underwriting discount and the
$.005 per share partial reimbursement of expenses to the underwriters) exceeds
$.03 per share of common stock. The Investment Adviser has agreed to pay all of
the Fund's organizational expenses.

Overallotment Option

      The Fund has granted the underwriters an option to purchase up to
additional shares at the public offering price less the underwriting discount.
The underwriters may exercise the option from time to time for 45 days from the
date of this prospectus solely to cover any overallotments. If the underwriters
exercise this option, each will be obligated, subject to conditions contained in
the purchase agreement, to purchase a number of additional shares proportionate
to that underwriter's initial amount reflected in the above table.

Price Stabilization, Short Positions and Penalty Bids

      Until the distribution of the shares is completed, Commission rules may
limit the underwriters and selling group members from bidding for and purchasing
the Fund's shares. However, the representatives may engage in transactions that
stabilize the price of the shares, such as bids or purchases to peg, fix or
maintain that price.

      If the underwriters create a short position in the shares in connection
with the offering, i.e., if they sell more shares than are listed on the cover
of this prospectus, the representative may reduce that short position by
purchasing shares in the open market. The representative also may elect to
reduce any short position by exercising all or part of the overallotment option
described above. Purchases of the shares to stabilize its price or to reduce a
short position may cause the price of the shares to be higher than it might be
in the absence of such purchases.

      The representative also may impose a penalty bid on underwriters and
selling group members. This means that if the representative purchases shares in
the open market to reduce the underwriters' short position or to stabilize the
price of such shares, it may reclaim the amount of the selling concession from
the underwriters and selling group members who sold those shares. The imposition
of a penalty bid also may affect the price of the shares in that it discourages
resales of those shares.

      Neither the Fund nor any of the underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the shares. In addition, neither the
Fund nor any of the underwriters makes any representation that the
representative will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.


                                       56


Stock Exchange Listing

      Prior to this offering, there has been no public market for the shares.
The Fund plans to apply to list its shares on the NYSE or another national
securities exchange under the symbol "MUI". However, during an initial period
that is not expected to exceed two weeks from the date of this prospectus, the
Fund's shares will not be listed on any securities exchange. Additionally,
before it begins trading, the underwriters do not intend to make a market in the
Fund's shares, although a limited market may develop. Thus, it is anticipated
that investors may not be able to buy and sell shares of the Fund during such
period. In order to meet the requirements for listing, the underwriters have
undertaken to sell lots of 100 or more shares to a minimum of 2,000 beneficial
owners.

Other Relationships

      The Investment Adviser (and not the Fund) also has agreed to pay a fee to
Merrill Lynch quarterly at the annual rate of 0.10% of the Fund's average daily
net assets through July , 2008 and at the annual rate of 0.15% of the Fund's
average daily net assets thereafter during the continuance of the Investment
Advisory Agreement. The maximum amount of this fee, plus the partial
reimbursement of underwriting expenses discussed above, will not exceed 4.5% of
the aggregate initial offering price of the common stock offered hereby;
provided, that in determining when the maximum amount has been paid the value of
each of the quarterly payments shall be discounted at the annual rate of 10%
back to the closing date of this offering. Merrill Lynch has agreed to provide
certain after-market services to the Investment Adviser designed to maintain the
visibility of the Fund on an ongoing basis and to provide relevant information,
studies or reports regarding the Fund and the closed-end investment company
industry.

      The Fund anticipates that Merrill Lynch and other underwriters may from
time to time act as brokers in connection with the execution of its portfolio
transactions, and after they have ceased to be underwriters, the Fund
anticipates that underwriters other than Merrill Lynch may from time to time act
as dealers in connection with the execution of portfolio transactions. See
"Portfolio Transactions." Merrill Lynch is an affiliate of the Investment
Adviser.

                  NOTES TO STATEMENT OF ASSETS AND LIABILITIES

Note 1. Organization

      The Fund was incorporated under the laws of the State of Maryland on May
15, 2003 and is registered under the Investment Company Act of 1940 as a
closed-end, non-diversified management investment company and has had no
operations other than the sale to Fund Asset Management, L.P. (the "Investment
Adviser") of an aggregate of shares for $        on July   , 2003. The General
Partner of the Investment Adviser is an indirect wholly-owned subsidiary of
Merrill Lynch & Co., Inc. Certain officers and/or directors of the Fund are
officers of the Investment Adviser.


      The Investment Adviser, on behalf of the Fund, will incur organization
costs estimated at $         . To the extent that the Fund's offering costs
otherwise do not exceed $.03 per share of common stock, the Fund has agreed to
pay the underwriters up to $.005 per share of common stock as a partial
reimbursement of expenses inccurred in connection with the offering. However, in
no event will the Fund pay offering costs (other than the underwriting discount,
but including the partial reimbursement to the underwriters) in excess of $.03
per share of common stock. The Investment Adviser or an affiliate will pay the
amount by which the offering costs of the Fund (other than the underwriting
discount, and the $.005 per share partial reimbursement of expenses to the
underwriters) exceeds $.03 per share of common stock. Direct costs relating to
the public offering of the Fund's shares will be charged to capital at the time
of issuance of shares.



                                       60


Note 2. Investment Advisory Arrangements

      The Fund has engaged the Investment Adviser to provide investment advisory
and management services to the Fund. The Investment Adviser will receive a
monthly fee for advisory and management services at an annual rate of 0.55% of
the Fund's average daily net assets (including any proceeds from the issuance of
preferred stock), plus the proceeds of any outstanding borrowings used for
leverage.

      The Investment Adviser has contractually agreed to waive a portion of its
fee during the first five full years of operations at the annual rate of 0.15%
of the average daily net assets of the Fund and at a declining rate for an
additional two years. The Investment Adviser has not agreed to waive any portion
of its fee beyond the seven year period.

Note 3. Federal Income Taxes

      The Fund intends to qualify as a "regulated investment company" and as
such (and by complying with the applicable provisions of the Internal Revenue
Code of 1986, as amended) will not be subject to Federal income tax on taxable
income (including realized capital gains) that is distributed to stockholders.

                           RATINGS OF MUNICIPAL BONDS

Description of Moody's Investors Service, Inc.'s ("Moody's") Municipal Bond
Ratings

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

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

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

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

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

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

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

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

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

      Note: Those bonds in the Aa, A, Baa, Ba and B groups which Moody's
believes possess the strongest investment attributes are designated by the
symbols Aa1, A1, Baa1, Ba1 and B1.


                                      A-1


      Short term Notes: The three ratings of Moody's for short term notes are
MIG 1/VMIG 1, MIG 2/VMIG 2, and MIG 3/VMIG 3; MIG 1/VMIG 1 denotes "best
quality, enjoying strong protection from established cash flows"; MIG 2/VMIG 2
denotes "high quality" with "ample margins of protection"; MIG 3/VMIG 3
instruments are of "favorable quality . . . but . . . lacking the undeniable
strength of the preceding grades."

Description of Moody's Commercial Paper Ratings

      Moody's Commercial Paper ratings are opinions of the ability of issuers to
honor senior financial obligations and contracts. Such obligations generally
have an original maturity not exceeding one year, unless explicitly noted.
Moody's employs the following three designations, all judged to be investment
grade, to indicate the relative repayment ability of rated issuers:

      Issuers rated Prime-1 (or supporting institutions) have a superior ability
for repayment of senior short term debt obligations. Prime-1 repayment ability
will often be evidenced by many of the following characteristics: leading market
positions in well established industries; high rates of return on funds
employed; conservative capitalization structures with moderate reliance on debt
and ample asset protection; broad margins in earning coverage of fixed financial
charges and high internal cash generation; and well established access to a
range of financial markets and assured sources of alternate liquidity.

      Issuers rated Prime-2 (or supporting institutions) have a strong ability
to repay senior short term debt obligations. This will normally be evidenced by
many of the characteristics cited above, but to a lesser degree. Earnings trends
and coverage ratios, while sound, may be more subject to variation.
Capitalization characteristics, while still appropriate, may be more affected by
external conditions. Ample alternate liquidity is maintained.

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

      Issuers 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"), Municipal Debt Ratings

      A Standard & Poor's municipal debt 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.

      The debt 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 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 circumstances.

      The 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;


                                      A-2


            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.

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

AA            An obligation rated "AA" differs from the highest rated 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.

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

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

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

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

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

C             A subordinated debt or preferred stock obligation rated "C" is
              CURRENTLY HIGHLY VULNERABLE to nonpayment. The "C" rating may be
              used to cover a situation where a bankruptcy petition has been
              filed or similar action taken, but payments on this obligation are
              being continued. A `C' also will be assigned to a preferred stock
              issue in arrears on dividends or sinking fund payments, but that
              is currently paying.

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


                                      A-3


      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 Commercial Paper Ratings

      A Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. Ratings are graded into several categories, ranging from "A-1" for the
highest-quality obligations to "D" for the lowest. These categories are as
follows:

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

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

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

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

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

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

      A commercial paper 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.


                                      A-4


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.

      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.

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.


                                      A-5


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

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.

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.

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.

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


                                      A-6


      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 municipal 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.

*     An investor's marginal tax rates may exceed the rates shown in the above
      table due to the reduction, or possible elimination, of the personal
      exemption deduction for high-income taxpayers and an overall limit on
      itemized deductions. Income also may be subject to certain state and local
      taxes. For investors who pay Federal alternative minimum tax, tax exempt
      yields may be equivalent to lower taxable yields than those shown above.
      The tax rates shown above do not apply to corporate taxpayers. The tax
      characteristics of the Fund are described more fully elsewhere in this
      prospectus. Consult your tax adviser for further details. This chart is
      for illustrative purposes only and cannot be taken as an indication of
