                                 COMMON SHARES
 
                                 -------------
  MuniHoldings Florida Insured Fund IV (the "Fund") is a newly organized, non-
diversified, closed-end management investment company that seeks to provide
shareholders with current income exempt from Federal income tax and the
opportunity to own shares having a value that is exempt from Florida intangible
personal property tax. The Fund seeks to achieve its objective by investing
primarily in a portfolio of long-term, investment grade municipal obligations
the interest on which, in the opinion of bond counsel to the issuer, is exempt
from Federal income tax and which enable shares of the Fund to be exempt from
Florida intangible personal property tax. The Fund intends to invest in
municipal obligations that are rated investment grade, or if unrated, are
considered by the Fund's investment adviser to be of comparable quality. Under
normal circumstances, at least 80% of the Fund's assets will be invested in
municipal obligations with remaining maturities of one year or more that are
covered by insurance guaranteeing the timely payment of principal at maturity
and interest.
 
  Because the Fund is newly organized, its shares have no history of public
trading. Shares of closed-end investment companies frequently trade at a
discount from their net asset value. This risk may be greater for investors
expecting to sell their shares in a relatively short period after completion of
the public offering. The Fund plans to apply to list its shares on the New York
Stock Exchange under the symbol "MFR." Trading of the Fund's common shares on
the exchange is expected to begin within two weeks of the date of this
prospectus. Before it begins trading, the underwriter does not intend to make a
market in the Fund's shares. Thus, investors may not be able to buy and sell
shares of the Fund during that time.
 
  Within approximately three months after completion of this offering of common
shares, the Fund intends to offer preferred shares representing approximately
40% of the Fund's capital immediately after the issuance of such preferred
shares. There can be no assurance, however, that preferred shares representing
such percentage of the Fund's capital will actually be issued. The use of
preferred shares to leverage the common shares can create special risks.
 
                                 -------------
  This prospectus contains information you should know before investing,
including information about risks. Please read it before you invest and keep it

THIS PROSPECTUS.

                               PROSPECTUS SUMMARY
 
  This summary is qualified in its entirety by reference to the detailed
information included in this prospectus.
 
THE FUND    MuniHoldings Florida Insured Fund IV (the "Fund") is a newly
            organized, non-diversified, closed-end management investment
            company.
 
THE         The Fund is offering     common shares at an initial offering price
OFFERING    of $   per share. The common shares are being offered by Merrill
            Lynch, Pierce, Fenner & Smith Incorporated, as underwriter. The
            underwriter may also purchase up to an additional      common
            shares within 45 days of the date of this prospectus to cover over-
            allotments.
 
INVESTMENT  The investment objective of the Fund is to provide shareholders
OBJECTIVE   with current income exempt from Federal income tax and the
AND         opportunity to own shares having a value that is exempt from
POLICIES    Florida intangible personal property tax. The Fund seeks to achieve
            its objective by investing primarily in a portfolio of long-term,
            investment grade municipal obligations the interest on which, in
            the opinion of bond counsel to the issuer, is exempt from Federal
            income tax and which enable shares of the Fund to be exempt from
            Florida intangible personal property tax.
 
            Investment Grade Municipal Bonds. The Fund intends to invest in
            municipal bonds that are rated investment grade by one or more
            nationally recognized statistical rating agencies or, if unrated,
            are considered by the investment adviser to be of comparable
            quality.
 
            Florida Municipal Bonds. The Fund will generally invest
            substantially all (at least 80%) of its assets in Florida municipal
            bonds. However, when the Fund's investment adviser believes that
            investment grade Florida municipal bonds are not available in
            sufficient amounts at an appropriate price, the Fund may invest a
            lesser amount of its assets in these securities. At all times,
            except during periods when the Fund is in the process of investing
            its proceeds from a public offering or during temporary defensive
            periods, the Fund intends to invest at least 65% of its assets in
            Florida municipal bonds and at least 80% of its assets in Florida
            municipal bonds and other long-term municipal bonds. These other
            long-term municipal bonds that the Fund may buy will be exempt from
            Federal income tax but their value will not be exempt from Florida
            intangible personal property tax.
 
            The Fund will normally invest at least 80% of its assets in insured
            municipal obligations with remaining maturities of one year or
            more. Insured municipal obligations are covered by insurance that
            guarantees timely interest payments and the repayment of principal
            on maturity.
 
            In general, the Fund does not intend its investments to earn a
            large amount of income that is not exempt from Federal income tax
            or to hold substantial assets which would subject shares of the
            Fund to Florida intangible personal property tax.
 
            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
 
                                       3
<PAGE>
 
            securities whose return is inversely related to changes in an
            interest rate (inverse floaters). In general, inverse floaters
            change in value in a manner that is opposite to most bonds -- that
            is, interest rates on inverse floaters will decrease when short
            term rates increase and increase when short term rates decrease.
            Investments in inverse floaters may subject the Fund to the risks
            of reduced or eliminated interest payments and losses 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.
 
            Options and Futures Transactions. The Fund may seek to hedge its
            portfolio against changes in interest rates using options and
            financial futures contracts. 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 does not, however,
            enter options and futures transactions for speculative purposes.
            The Fund is not required to hedge its portfolio and may not do so.
 
LEVERAGE    Issuance of Preferred Shares. The Fund intends to offer preferred
            shares within three months after completion of this offering. The
            preferred shares will represent approximately 40% of the Fund's
            capital, including the capital raised by issuing the preferred
            shares. There can be no assurance, however, that preferred shares
            will actually be issued. Issuing preferred shares will result in
            the leveraging of the common shares. Although the Board of Trustees
            has not yet determined the terms of the preferred shares offering,
            the Fund expects that the preferred shares will pay dividends that
            will be adjusted over either relatively short-term periods
            (generally seven to 28 days) or medium-term periods (up to five
            years). The preferred shares dividend rate will be based upon
            prevailing interest rates for debt obligations of comparable
            maturity. The money raised by the preferred shares offering will be
            invested in longer-term obligations in accordance with the Fund's
            investment objective. The expenses of the preferred shares, which
            will be borne by the Fund, will reduce the net asset value of the
            common shares. In addition, at times when the Fund is required to
            allocate taxable income to preferred shareholders, the terms of the
            preferred shares require the Fund to make an additional
            distribution to them. The amount of this additional distribution
            approximately equals the tax liability resulting from the
            allocation and the additional distribution (an "Additional
            Distribution"). During periods when the Fund has preferred shares
            outstanding, the Fund will pay fees to the investment adviser for
            its services that are higher than if the Fund did not issue
            preferred shares because the fees will be calculated on the basis
            of the Fund's average weekly net assets, including proceeds from
            the sale of preferred shares.
 
            Potential Benefits of Leverage. Under normal market conditions,
            longer term obligations produce higher yields than short and medium
            term obligations. The Fund's investment adviser
 
                                       4
<PAGE>
 
            believes that the interest income the Fund receives from its long
            term investments will exceed the amount of interest the Fund must
            pay to the preferred shareholders. Thus, the Fund's use of
            preferred shares should provide common shareholders with a higher
            yield than they would receive if the Fund were not leveraged.
 
            Risks. The use of leverage creates certain risks for common
            shareholders, including higher volatility of both the net asset
            value and the market value of the common shares. Since any decline
            in the value of the Fund's investments will affect only the common
            shareholders, 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 common shares.
            In addition, fluctuations in the dividend rates paid on, and the
            amount of taxable income allocable to, the preferred shares will
            affect the yield to common shareholders. There can be no assurance
            that the Fund will earn a higher net return on its investments than
            the then current dividend rate (and any Additional Distribution) it
            pays on the preferred shares. Under certain conditions, the benefit
            of leverage to common shareholders will be reduced, and the Fund's
            leveraged capital structure could result in a lower rate of return
            to common shareholders than if the Fund were not leveraged.
 
            Distributions. When the Fund issues preferred shares, common
            shareholders will receive all of the Fund's net income that remains
            after it pays dividends (and any Additional Distribution) on the
            preferred shares and generally will be entitled to a pro rata share
            of net realized capital gains. If the Fund is liquidated, preferred
            shareholders will be entitled to receive liquidating distributions
            before any distribution is made to common shareholders. These
            liquidating distributions are expected to equal the original
            purchase price per share of preferred shares plus any accumulated
            and unpaid dividends and Additional Distributions.
 
            Redemption of Preferred Shares. The Fund may redeem the preferred
            shares for any reason. The Fund may redeem all or part of the
            preferred shares if it believes that the Fund's leveraged capital
            structure will cause common shareholders to obtain a lower return
            than they would if the common shares were unleveraged for any
            significant amount of time.
 
            Voting Rights. Preferred shareholders, voting as a separate class,
            will be entitled to elect two of the Fund's Trustees. Common and
            preferred shareholders, voting together as a single class, will be
            entitled to elect the remaining Trustees. If the Fund fails to pay
            dividends to the preferred shareholders for two full years, the
            holders of all outstanding shares of preferred shares, voting as a
            separate class, would then be entitled to elect a majority of the
            Fund's Trustees. The preferred shareholders also will vote
            separately on certain other matters as required under the Fund's
            Declaration of Trust, the Investment Company Act of 1940, as
            amended, and Massachusetts law. Otherwise, common and preferred
            shareholders will have equal voting rights (one vote per share) and
            will vote together as a single class.
 
            Ratings. Before it offers the preferred shares, the Fund intends to
            apply to one or more nationally recognized statistical ratings
            organizations for ratings on the preferred shares. The
 
                                       5
<PAGE>
 
               Fund believes that a rating for the preferred shares will make it
               easier to market the shares, which should reduce its dividend
               rate.
  
LISTING        Currently, there is no public market for the Fund's common
               shares. However, the Fund plans to apply to list the Fund's
               common shares on the New York Stock Exchange. Trading of the
               Fund's common shares is expected to begin within two weeks of the
               date of this prospectus. Before it begins trading, the
               underwriter does not intend to make a market in the Fund's common
               shares. Thus, investors may not be able to buy and sell shares of
               the Fund during that period.
 
INVESTMENT     Fund Asset Management, L.P. is the Fund's investment adviser and
ADVISER        provides investment advisory and management services to the Fund.
               For its services, the Fund pays the investment adviser a fee at
               the annual rate of % of the Fund's average weekly net assets,
               including assets acquired from the sale of preferred shares.
 
              
              
              
DIVIDENDS      The Fund intends to distribute dividends equal to substantially
AND            all of its net investment income to common shareholders each
DISTRIBUTIONS  month. Once the Fund issues preferred shares, the monthly
               distributions to common shareholders will consist of
               substantially all net investment income that remains after the
               Fund pays dividends (and any Additional Distribution) on the
               preferred shares. The Fund expects to begin paying dividends to
               common shareholders within approximately 90 days from the date of
               this prospectus. The Fund will distribute net capital gains, if
               any, at least annually to common shareholders and, after it
               issues the preferred shares, on a pro rata basis to common and
               preferred shareholders. When the Fund allocates capital gains or
               other taxable income to preferred shareholders, under certain
               circumstances, the terms of the preferred shares may require the
               Fund to make an Additional Distribution. The Fund may not declare
               any cash dividend or other distribution on its common shares
               unless the preferred shares has asset coverage of at least 200%.
               If the Fund issues preferred shares representing 40% of its total
               capital, the preferred share's asset coverage will be
               approximately 250%. If the Fund's ability to make distributions
               on its common shares is limited, the Fund may not be able to
               qualify for taxation as a regulated investment company. This
               would have adverse tax consequences for common shareholders.
 
AUTOMATIC      Dividend and capital gains distributions generally are used to
DIVIDEND       purchase additional common shares. However, an investor can
REINVESTMENT   choose to receive distributions in cash. Since not all investors
PLAN           can participate in the automatic dividend reinvestment plan, you
               should call your broker or nominee to confirm that you are
               eligible to participate in the plan.
 
MUTUAL         Investors who purchase shares in this offering through the
FUND           underwriter and later sell their shares have the option, subject
INVESTMENT     to certain conditions, to purchase Class D shares of certain
OPTION         Merrill Lynch funds with the proceeds from the sale.

                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
  Liquidity and Market Price of Shares. The Fund is newly organized and has no
operating history or history of public trading. Before the Fund's common shares
are listed on the New York Stock Exchange, an investment in the Fund may be
illiquid.
 
  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." Investors who sell their shares within
a relatively short period after completion of the public offering are more
likely to be exposed to this risk. The Fund is designed primarily for long-term
investors and should not be considered a vehicle for trading purposes.
 
  Florida Municipal Bonds. The Fund intends to invest the majority of its
portfolio in Florida municipal bonds. As a result, the Fund is more exposed to
risks affecting issuers of Florida municipal bonds than is a municipal bond
fund that invests more widely.
 
  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. Even as a non-
diversified fund, the Fund must still meet the diversification requirements of
applicable Federal tax laws. Since the Fund may invest a relatively high
percentage of its assets in a limited number of issuers, the Fund may be more
exposed than a more widely-diversified fund to any single economic, political
or regulatory occurrence.
 
  Rating Categories. The Fund intends to invest in municipal bonds that are
rated investment grade by Standard & Poor's, Moody's Investors Service, Inc.
and Fitch IBCA, Inc. It may also invest in unrated municipal bonds that the
Fund's investment adviser believes are of comparable quality. Obligations rated
in the lowest investment grade category may have certain speculative
characteristics.
 
  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 alternative minimum tax. See "Taxes--General."
 
  Taxes. It is possible that the Fund may not be able to fully dispose of all
of its assets subject to Florida intangible personal property tax by the last
business day of the calendar year. This would subject shares of the Fund to
Florida intangible personal property tax.
 
  Portfolio Insurance and Rating Agencies. The Fund will be subject to certain
investment restrictions imposed by guidelines of the insurance companies that
issue portfolio insurance and to guidelines of one or more nationally
recognized statistical ratings organizations that may issue ratings for the
preferred shares. These guidelines may impose asset coverage or portfolio
composition requirements that are more stringent than those imposed by the
Investment Company Act of 1940, as amended. The Fund does not expect these
requirements or guidelines to prevent the investment adviser from managing the
Fund's portfolio in accordance with the Fund's investment objective and
policies.
 
 
                                       7
<PAGE>
 
  Leverage. The Fund plans to offer preferred shares. The preferred stock will
represent approximately 40% of the Fund's capital including capital raised by
issuing the preferred shares. Leverage creates certain risks for common
shareholders, including higher volatility of both the net asset value and the
market value of the common shares. Leverage also creates the risk that the
investment return on the Fund's common shares will be reduced to the extent the
dividends paid on preferred shares and other expenses of the preferred shares
exceed the income earned by the Fund on its investments. If the Fund is
liquidated, preferred shareholders will be entitled to receive liquidating
distributions before any distribution is made to common shareholders.
 
  Inverse Floating Obligations. The Fund's investments in "inverse floating
obligations" or "residual interest bonds" provide investment leverage because
their market value increases or decreases in response to a market change at a
greater rate than fixed rate, long term tax exempt securities. The market
values of such securities are more volatile than the market values of fixed
rate, tax exempt securities.
 
  Options and Futures Transactions. The Fund may engage in certain options and
futures transactions to reduce its exposure to interest rate movements. If the
Fund incorrectly forecasts market values, interest rates or other factors, the
Fund's performance could suffer. The Fund also may suffer a loss if the other
party to the transaction fails to meet its obligations. The Fund is not
required to use hedging and may not do so.
 
  Antitakeover Provisions. The Fund's Declaration of Trust includes 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 Trustees. Such provisions
could limit the ability of shareholders to sell their shares at a premium over
prevailing market prices by discouraging a third party from seeking to obtain
control of the Fund.

                                   THE FUND
 
  MuniHoldings Florida Insured Fund IV (the "Fund") is a newly organized, non-
diversified, closed-end management investment company. The Fund was organized
under the laws of The Commonwealth of Massachusetts on November 25, 1998, and
has registered under 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 has been 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
generally make a continuous offering of their shares or redeem their
securities at the option of the shareholder, whereas open-end companies issue
securities redeemable at net asset value at any time at the option of the
shareholder 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. Shares of
closed-end investment companies, however, frequently trade at a discount from
their net asset value. This risk may be greater for investors expecting to
sell their shares in a relatively short period after completion of the public
offering.
 
                                USE OF PROCEEDS
 
  The net proceeds of this offering will be approximately $     (or
approximately $     assuming the Underwriter exercises the over-allotment
option in full) after payment of organizational and offering expenses
estimated to be approximately $    .
 
  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 shares, 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 shareholders with current
income exempt from Federal income tax and the opportunity to own shares having
a value that is exempt from Florida intangible personal property tax. The Fund
will seek to achieve its objective by investing primarily in a portfolio of
long-term, investment grade municipal obligations issued by or on behalf of
the State of Florida, its political subdivisions, agencies and
instrumentalities and by other qualifying issuers that pay interest that, in
the opinion of bond counsel to the issuer, is exempt from Federal income tax
and which enable shares of the Fund to be exempt from Florida intangible
personal property tax ("Florida Municipal Bonds"). The Fund intends to invest
substantially all (a minimum of 80%) of its assets in Florida Municipal Bonds,
except at times when the Fund's investment adviser, Fund Asset Management,
L.P. (the "Investment Adviser"), considers that Florida Municipal Bonds of
sufficient quality and quantity are unavailable for investment at suitable
prices by the Fund. To the extent the Investment Adviser considers that
suitable Florida Municipal Bonds are not available for investment, the Fund
may purchase other long-term municipal obligations the interest on which is
exempt from Federal income taxes but the value of which is not exempt from
Florida intangible personal property taxes ("Municipal Bonds"). The Fund will
maintain at least 65% of its assets in Florida Municipal Bonds and at least
80% of its assets in Florida Municipal Bonds and Municipal Bonds, except
during interim periods pending investment of the net proceeds of public
offerings of the Fund's securities and during temporary defensive periods.
Under normal circumstances,
 
                                      10
<PAGE>
 
at least 80% of the Fund's assets will be invested in municipal obligations
with remaining maturities of one year or more that are covered by insurance
guaranteeing the timely payment of principal at maturity and interest. The
Fund's investment objective is a fundamental policy that may not be changed
without a vote of a majority of the Fund's outstanding voting securities, as
defined below under "Investment Restrictions." There can be no assurance that
the investment objective of the Fund will be realized. At times the Fund may
seek to hedge its portfolio through the use of futures transactions and
options to reduce volatility in the net asset value of its common shares.
 
  The Fund ordinarily does not intend to realize significant investment income
that is subject to Federal income tax or have significant assets subject to
Florida intangible personal property tax. The Fund may invest all or a portion
of its assets in certain tax-exempt securities classified as "private activity
bonds" (in general, bonds that benefit non-governmental entities) that may
subject certain investors in the Fund to an alternative minimum tax.
 
  The Fund also 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
nevertheless believes such securities pay interest or distributions that are
exempt from Federal income taxation ("Non-Municipal Tax-Exempt Securities").
Non-Municipal Tax-Exempt Securities may include securities issued by other
investment companies that invest in Florida Municipal Bonds and Municipal
Bonds, to the extent such investments are permitted by the Investment Company
Act of 1940, as amended (the "1940 Act"). Other Non-Municipal Tax-Exempt
Securities could include trust certificates or other instruments evidencing
interests in one or more long-term Florida Municipal Bonds or Municipal Bonds.
Certain Non-Municipal Tax-Exempt Securities may be characterized as derivative
instruments. Non-Municipal Tax-Exempt Securities are considered "Florida
Municipal Bonds" or "Municipal Bonds" for purposes of the Fund's investment
objective and policies.
 
  Investment in common shares of the Fund offers several potential benefits.
The Fund offers investors the opportunity to receive income exempt from
Federal income tax and to hold Fund shares exempt from Florida intangible
personal property tax by investing in a professionally managed portfolio
comprised primarily of investment grade insured Florida Municipal Bonds.
Investment in the Fund also relieves the investor of the burdensome
administrative details involved in managing a portfolio of Florida Municipal
Bonds. Additionally, the Investment Adviser will seek to enhance the yield on
the common shares by leveraging the Fund's capital structure through the
issuance of preferred shares. The benefits are at least partially offset by
the expenses involved in operating an investment company. Such expenses
primarily consist of the advisory fee and operational costs. Additionally, the
use of leverage involves certain expenses and special risk considerations. See
"Risks and Special Considerations of Leverage."
 
  The investment grade Florida Municipal Bonds and Municipal Bonds in which
the Fund will primarily invest are those Florida Municipal Bonds and Municipal
Bonds rated at the date of purchase in the four highest rating categories of
Standard & Poor's ("S&P"), Moody's Investors Services, Inc. ("Moody's") or
Fitch IBCA, Inc. ("Fitch"), or, if unrated, are considered to be of comparable
quality by the Investment Adviser. In the case of long-term debt, the
investment grade rating categories are AAA through BBB for S&P, Aaa through
Baa for Moody's and AAA through BBB for Fitch. In the case of short-term
notes, the investment grade rating categories are SP-1+ through SP-3 for S&P,
MIG-1 through MIG-3 for Moody's and F-1+ through F-3 for Fitch. In the case of
tax-exempt commercial paper, the investment grade rating categories are A-1+
through A-3 for S&P, Prime-1 through Prime-3 for Moody's and F-1+ through F-3
for Fitch. Obligations ranked in the fourth highest rating category (BBB, SP-3
and A-3 for S&P; Baa, MIG-3 and Prime-3 for Moody's; and BBB and F-3 for
Fitch), while considered "investment grade," may have certain speculative
characteristics. There may be sub-categories or gradations indicating relative
standing within the rating categories set forth above. See Appendix II to this
Prospectus for a description of S&P's, Moody's and Fitch's ratings of
Municipal Bonds. In assessing the
 
                                      11
<PAGE>
 
quality of Florida Municipal Bonds and Municipal Bonds with respect to the
foregoing requirements, the Investment Adviser will take into account the
portfolio insurance as well as the nature of any letters of credit or similar
credit enhancements to which particular Florida Municipal Bonds and Municipal
Bonds are entitled and the creditworthiness of the insurance company or
financial institution that provided such insurance or credit enhancement.
Consequently, if Florida Municipal Bonds or Municipal Bonds are covered by
insurance policies issued by insurers whose claims-paying ability is rated AAA
by S&P or Fitch or Aaa by Moody's, the Investment Adviser may consider such
municipal obligations to be equivalent to AAA- or Aaa- rated securities, as
the case may be, even though such Florida Municipal Bonds or Municipal Bonds
would generally be assigned a lower rating if the rating were based primarily
upon the credit characteristics of the issuers without regard to the insurance
feature. The insured Florida Municipal Bonds and Municipal Bonds must also
comply with the standards applied by the insurance carriers in determining
eligibility for portfolio insurance.
 
  The Fund's investments may also include 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, typically a commercial bank. The VRDOs in which the Fund will
invest are tax-exempt obligations, in the opinion of counsel to the issuer,
that contain a floating or variable interest rate adjustment formula and an
unconditional right of demand on the part of the holder thereof to receive
payment of the unpaid principal balance plus accrued interest on a short
notice period not to exceed seven days. Participating VRDOs provide the Fund
with a specified undivided interest (up to 100%) in 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 on a
specified number of days' notice, not to exceed seven days. There is, however,
the possibility that because of default or insolvency, the demand feature of
VRDOs or Participating VRDOs may not be honored. 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.
 
  The average maturity of the Fund's portfolio securities will vary based upon
the Investment Adviser's assessment of economic and market conditions. The net
asset value of the common shares of a closed-end investment company, such as
the Fund, which invests primarily in fixed-income securities, changes as the
general levels of interest rates fluctuate. When interest rates decline, the
value of a fixed-income portfolio can be expected to rise. Conversely, when
interest rates rise, the value of a fixed-income portfolio can be expected to
decline. Prices of longer-term securities generally fluctuate more in response
to interest rate changes than do short-term or medium-term securities. These
changes in net asset value are likely to be greater in the case of a fund
having a leveraged capital structure, as proposed for the Fund. See "Risks and
Special Considerations of Leverage."
 
  The Fund intends to invest primarily in long-term Florida Municipal Bonds
and Municipal Bonds with a maturity of more than ten years. Also, the Fund may
invest in intermediate-term Florida Municipal Bonds and Municipal Bonds with a
maturity of between three years and ten years. The Fund may invest in short-
term, tax-exempt securities, short-term U.S. Government securities, repurchase
agreements or cash. Such short-term securities or cash will not exceed 20% of
its total assets except during interim periods pending investment of the net
proceeds of public offerings of the Fund's securities or in anticipation of
the repurchase or redemption of the Fund's securities and temporary periods
when, in the opinion of the Investment Adviser, prevailing market or economic
conditions warrant. The Fund does not ordinarily intend to realize significant
interest income that is subject to Federal income tax or to hold assets which
would subject Fund shares to Florida intangible personal property taxes.
 
 
                                      12
<PAGE>
 
  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.
However, the Fund's investments will be limited so as to qualify the Fund for
special tax treatment afforded regulated investment companies under the
Federal tax laws. See "Taxes." To qualify, among other requirements, the Fund
will limit 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 (other than U.S. Government
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 (other than U.S. Government
securities) of a single issuer. A fund that elects to be classified as
"diversified" under the 1940 Act must satisfy the foregoing 5% requirement
with respect to 75% of its total assets. To the extent that the Fund assumes
large positions in the securities of a small number of issuers, the Fund's
yield may fluctuate to a greater extent than that of a diversified company as
a result of changes in the financial condition or in the market's assessment
of the issuers.
 
PORTFOLIO INSURANCE
 
  Under normal circumstances, at least 80% of the Fund's assets will be
invested in Florida Municipal Bonds and Municipal Bonds either (i) insured
under an insurance policy purchased by the Fund or (ii) insured under an
insurance policy obtained by the issuer thereof or any other party. The Fund
will seek to limit its investments to municipal bonds insured under insurance
policies issued by insurance carriers that have total admitted assets
(unaudited) of at least $75,000,000 and capital and surplus (unaudited) of at
least $50,000,000 and insurance claims-paying ability ratings of AAA from S&P
or Fitch or Aaa from Moody's. There can be no assurance that insurance from
insurance carriers meeting these criteria will be at all times available. See
Appendix III to this Prospectus for a brief description of S&P's, Fitch's and
Moody's insurance claims-paying ability ratings. Currently, it is anticipated
that a majority of the insured Florida Municipal Bonds and Municipal Bonds in
the Fund's portfolio will be insured by the following insurance companies that
satisfy the foregoing criteria: AMBAC Indemnity Corporation, Financial
Guaranty Insurance Company, Financial Security Assurance and Municipal Bond
Investors Assurance Corporation. The Fund also may purchase Florida Municipal
Bonds and Municipal Bonds covered by insurance issued by any other insurance
company that satisfies the foregoing criteria. It is anticipated that
initially a majority of insured Florida Municipal Bonds and Municipal Bonds
held by the Fund will be insured under policies obtained by parties other than
the Fund.
 
  The Fund may purchase, but has no obligation to purchase, separate insurance
policies (the "Policies") from insurance companies meeting the criteria set
forth above that guarantee the payment of principal and interest on specified
eligible Florida Municipal Bonds and Municipal Bonds purchased by the Fund. A
Florida Municipal Bond and a Municipal Bond will be eligible for coverage if
it meets certain requirements of the insurance company set forth in a Policy.
In the event interest or principal on an insured Florida Municipal Bond and
Municipal Bond is not paid when due, the insurer will be obligated under its
Policy to make such payment not later than 30 days after it has been notified
by, and provided with documentation from, the Fund that such nonpayment has
occurred.
 
  The Policies will be effective only as to insured Florida Municipal Bonds
and Municipal Bonds beneficially owned by the Fund. In the event of a sale of
any Florida Municipal Bonds and Municipal Bonds held by the Fund, the issuer
of the relevant Policy will be liable only for those payments of interest and
principal that are then due and owing. The Policies will not guarantee the
market value of the insured Florida Municipal Bonds and Municipal Bonds or the
value of the shares of the Fund.
 
                                      13
<PAGE>
 
  The insurer will not have the right to withdraw coverage on securities
insured by their Policies and held by the Fund so long as such securities
remain in the Fund's portfolio. In addition, the insurer may not cancel its
Policies for any reason except failure to pay premiums when due. The Board of
Trustees of the Fund will reserve the right to terminate any of the Policies
if it determines that the benefits to the Fund of having its portfolio insured
under such policy are not justified by the expense involved.
 
  The premiums for the Policies are paid by the Fund and the yield on the
Fund's portfolio is reduced thereby. The Investment Adviser estimates that the
cost of the annual premiums for the Policies currently ranges from
approximately .02 of 1% to .15 of 1% of the principal amount of the Florida
Municipal Bonds and Municipal Bonds covered by such Policies. The estimate is
based on the expected composition of the Fund's portfolio of Florida Municipal
Bonds and Municipal Bonds. Additional information regarding the Policies is
set forth in Appendix III to this Prospectus. In instances in which the Fund
purchases Florida Municipal Bonds and Municipal Bonds insured under policies
obtained by parties other than the Fund, the Fund does not pay the premiums
for such policies; rather, the cost of such policies may be reflected in the
purchase price of the Florida Municipal Bonds and Municipal Bonds.
 
  It is the intention of the Investment Adviser to retain any insured
securities that are in default or in significant risk of default and to place
a value on the insurance, which ordinarily will be the difference between the
market value of the defaulted security and the market value of similar
securities that are not in default. In certain circumstances, however, the
Investment Adviser may determine that an alternate value for the insurance,
such as the difference between the market value of the defaulted security and
its par value, is more appropriate. The Investment Adviser's ability to manage
the portfolio may be limited to the extent the Fund holds defaulted
securities, which may limit its ability in certain circumstances to purchase
other Florida Municipal Bonds and Municipal Bonds. See "Net Asset Value" below
for a more complete description of the Fund's method of valuing defaulted
securities and securities that have a significant risk of default.
 
  There can be no assurance that insurance with the terms and issued by
insurance carriers meeting the criteria described above will continue to be
available to the Fund. In the event the Board of Trustees determines that such
insurance is unavailable or that the cost of such insurance outweighs the
benefits to the Fund, the Fund may modify the criteria for insurance carriers
or the terms of the insurance, or discontinue its policy of maintaining
insurance for all or any of the Florida Municipal Bonds and Municipal Bonds
held in the Fund's portfolio. Although the Investment Adviser periodically
reviews the financial condition of each insurer, there can be no assurance
that the insurers will be able to honor their obligations under all
circumstances.
 
  The portfolio insurance reduces financial or credit risk (i.e., the
possibility that the owners of the insured Florida Municipal Bonds or
Municipal Bonds will not receive timely scheduled payments of principal or
interest). However, the insured Florida Municipal Bonds or Municipal Bonds are
subject to market risk (i.e., fluctuations in market value as a result of
changes in prevailing interest rates).
 
DESCRIPTION OF FLORIDA MUNICIPAL BONDS AND MUNICIPAL BONDS
 
  Florida Municipal Bonds and Municipal Bonds include debt obligations issued
to obtain funds for various public purposes, including 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 industrial development bonds are
issued by or on behalf of public authorities to finance
 
                                      14
<PAGE>
 
various privately operated facilities, including certain local facilities for
water supply, gas, electricity, sewage or solid waste disposal. For purposes
of this prospectus, such obligations are Municipal Bonds if the interest paid
thereon is exempt from Federal income tax and are Florida Municipal Bonds if
the interest thereon is exempt from Federal income tax and the obligation is
exempt from Florida intangible personal property tax, even though such bonds
may be industrial development bonds ("IDBs") or "private activity bonds" as
discussed below. Also, for purposes of this prospectus, Non-Municipal Tax-
Exempt securities as discussed above will be considered Florida Municipal
Bonds or Municipal Bonds.
 
  The two principal classifications of Florida Municipal Bonds and Municipal
Bonds are "general obligation" bonds and "revenue" bonds, which latter
category includes IDBs and, for bonds issued after August 15, 1986, private
activity bonds. General obligation bonds are secured by the issuer's pledge of
faith, credit and taxing power for the repayment of principal and the payment
of interest. Revenue or special obligation 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
source such as from the user of the facility being financed. IDBs are in most
cases revenue bonds and do not generally constitute the pledge of the credit
or taxing power of the issuer of such bonds. The repayment of principal and
the payment of interest on such industrial development bonds depends solely on
the ability of the user of the facility financed by the bonds to meet its
financial obligations and the pledge, if any, of real and personal property so
financed as security for such payment. Florida Municipal Bonds and Municipal
Bonds may also include "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.
 
  The Fund may purchase Florida Municipal Bonds and Municipal Bonds classified
as "private activity bonds" (in general, bonds that benefit non-governmental
entities). Interest received on certain tax-exempt securities that are
classified as "private activity bonds" may subject certain investors in the
Fund to an alternative minimum tax. There is no limitation on the percentage
of the Fund's assets that may be invested in Florida Municipal Bonds and
Municipal Bonds that may subject certain investors to an alternative minimum
tax. See "Taxes--General." Also included within the general category of
Florida Municipal Bonds and Municipal Bonds are participation certificates
issued by government authorities or entities to finance the acquisition or
construction of equipment, land and/or facilities. The certificates represent
participations in a lease, an installment purchase contract or a conditional
sales contract (hereinafter collectively referred to as "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 frequently is 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 lease property, disposition of the
property in the event of foreclosure might prove difficult. These securities
represent a relatively new type of financing that has not yet developed the
depth of marketability associated with more conventional securities.
 
  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 Florida Municipal Bonds and Municipal Bonds for investment
by the Fund.

SPECIAL CONSIDERATIONS RELATING TO FLORIDA MUNICIPAL BONDS
 
  The Fund ordinarily will invest at least 80% of its total assets in Florida
Municipal Bonds, and therefore it is more susceptible to factors adversely
affecting issuers of Florida Municipal Bonds than is a municipal bond mutual
fund that is not concentrated in issuers of Florida Municipal Bonds to this
degree. Many different social, environmental and economic factors may affect
the financial condition of Florida and its political subdivisions. From time
to time Florida and its political subdivisions have encountered financial
difficulties. Florida is highly dependent upon sales and uses taxes, which
account for the majority of its General Fund revenues. The Florida
Constitution does not permit a state or local personal income tax. The
structure of personal income in Florida is also different from the rest of the
nation in that the State has a proportionally greater retirement age
population that is dependent upon transfer payments (social security, pension
benefits, etc.). Such transfer payments can be affected by Federal
legislation. Florida's economic growth is also highly dependent upon other
factors such as changes in population growth, tourism, interest rates and
hurricane activity. In combination, the two amendments to the Florida
Constitution may limit the State's ability to raise revenues and may have an
adverse effect on the finances of Florida and its political subdivisions. The
Investment Adviser does not believe that the current economic conditions in
Florida will have a significant adverse effect on the Fund's ability to invest
in investment grade Florida Municipal Bonds. For a discussion of economic and
other conditions in the State of Florida, see Appendix I, "Economic and Other
Conditions in Florida."
 
OTHER INVESTMENT POLICIES
 
  The Fund has adopted certain other policies as set forth below:
 
  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 shares pursuant to tender offers or
otherwise to redeem or repurchase preferred shares or for temporary,
extraordinary or emergency purposes. Borrowings by the Fund (commonly known,
as with the issuance of preferred shares, as "leveraging") create an
opportunity for greater total return since the Fund will not be required to
sell portfolio securities to repurchase or redeem shares but, at the same
time, increase exposure to capital risk. In addition, borrowed funds are
subject to interest costs that may offset or exceed the return earned on the
borrowed funds.
 
  When-Issued Securities and Delayed Delivery Transactions. The Fund may
purchase or sell Florida Municipal Bonds and Municipal Bonds on a delayed
delivery basis or on a when-issued basis at fixed purchase or sale terms.
These transactions arise when securities are purchased or sold by the Fund
with payment and delivery taking place in the future. The purchase will be
recorded on the date the Fund enters into the commitment, and the value of the
obligation will thereafter be reflected in the calculation of the Fund's net
asset value. The value of the obligation on the delivery day may be more or
less than its purchase price. A separate account of the Fund will be
established with its custodian consisting of cash, cash equivalents or liquid
securities having a market value at all times at least equal to the amount of
the commitment.
 
  Indexed and Inverse Floating Obligations. The Fund may invest in Florida
Municipal Bonds and Municipal Bonds yielding a return based on a particular
index of value or interest rates. For example, the Fund may invest in Florida
Municipal Bonds and Municipal Bonds that pay interest based on an index of
Municipal Bond interest rates. The principal amount payable upon maturity of
certain Florida Municipal Bonds and
 
                                      16
<PAGE>
 
Municipal Bonds also may be based on the value of an index. To the extent the
Fund invests in these types of Municipal Bonds, the Fund's return on such
Florida Municipal Bonds and Municipal Bonds will be subject to risk with
respect to the value of the particular index. Also, the Fund may invest in so-
called "inverse floating obligations" or "residual interest bonds" on which
the interest rates typically vary inversely with a short-term floating rate
(which may be reset periodically by a dutch auction, a remarketing agent, or
by reference to a short-term tax-exempt interest rate index). The Fund may
purchase synthetically-created inverse floating rate bonds evidenced by
custodial or trust receipts. Generally, interest rates on inverse floating
rate bonds will decrease when short-term rates increase, and will increase
when short-term 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 in market interest rates at a rate that 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 generally will 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 limitations on the extent to which
the interest rate may vary. The Investment Adviser believes that indexed and
inverse floating obligations represent a flexible portfolio management
instrument for the Fund that allows the Investment Adviser to vary the degree
of investment leverage relatively efficiently under different market
conditions.
 
  Call Rights. The Fund may purchase a Florida Municipal Bond or Municipal
Bond issuer's right to call all or a portion of such Florida Municipal Bond or
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 Florida Municipal Bonds or Municipal Bonds, subject to
certain conditions. A Call Right that is not exercised prior to the maturity
of the related Florida Municipal Bond or Municipal Bond will expire without
value. The economic effect of holding both the Call Right and the related
Florida Municipal Bond or Municipal Bond is identical to holding a Florida
Municipal Bond or Municipal Bond as a non-callable security.
 
  Repurchase Agreements. The Fund may invest in securities pursuant to
repurchase agreements. Repurchase agreements may be entered into only with a
member bank of the Federal Reserve System or a primary dealer in U.S.
Government securities or an affiliate thereof. Under such agreements, the
seller 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. The Fund may not invest in repurchase agreements
maturing in more than seven days if such investments, together with all other
illiquid investments, would exceed 15% of the Fund's net assets. In the event
of default by the seller under a repurchase agreement, the Fund may suffer
time delays and incur costs or possible losses in connection with the
disposition of the underlying securities.
 
  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.
 
OPTIONS AND FUTURES 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 ("financial futures contracts") and options
thereon.
 
                                      17
<PAGE>
 
While the Fund's use of hedging strategies is intended to reduce the
volatility of the net asset value of the common shares, the net asset value of
the common shares will fluctuate. There can be no assurance that the Fund's
hedging transactions will be effective. In addition, because of the
anticipated leveraged nature of the common shares, hedging transactions will
result in a larger impact on the net asset value of the common shares than
would be the case if the common shares were not leveraged. Furthermore, the
Fund has no obligation to enter into hedging transactions and may only engage
in hedging activities from time to time and may not necessarily be engaging in
hedging activities when movements in interest rates occur.
 
  Certain Federal income tax requirements may limit the Fund's ability to
engage in hedging transactions. Gains from transactions in options and futures
contracts distributed to shareholders will be taxable as ordinary income or,
in certain circumstances, as long-term capital gains to shareholders. See
"Taxes--Tax Treatment of Options and Futures Transactions." In addition, in
order to obtain ratings of the preferred shares from one or more nationally
recognized statistical ratings organizations ("NRSROs"), the Fund may be
required to limit its use of hedging techniques in accordance with the
specified guidelines of such organizations.
 
  The following is a description of the options and futures transactions in
which the Fund may engage, limitations on the Fund's use of such transactions
and risks associated with these transactions. The investment policies with
respect to the hedging transactions of the Fund are not fundamental policies
and may be modified by the Board of Trustees of the Fund without the approval
of the Fund's shareholders.
 
  Writing Covered Call Options. The Fund may write (i.e., sell) covered call
options with respect to Florida Municipal Bonds and Municipal Bonds it owns,
thereby giving the holder of the option the right to buy the underlying
security covered by the option from the Fund at the stated exercise price
until the option expires. The Fund writes only covered call options, which
means that so long as the Fund is obligated as the writer of a call option, it
will own the underlying securities subject to the option. The Fund may not
write covered call options on underlying securities in an amount exceeding 15%
of the market value of its total assets.
 
  The Fund will receive a premium from writing a call option, which increases
the Fund's return on the underlying security in the event the option expires
unexercised or is closed out at a profit. By writing a call, the Fund limits
its opportunity to profit from an increase in the market value of the
underlying security above the exercise price of the option for as long as the
Fund's obligation as a writer continues. Covered call options may serve as a
partial hedge against a decline in the price of the underlying security. The
Fund may engage in closing transactions in order to terminate outstanding
options that it has written.
 
  Purchase of Options. The Fund may purchase put options in connection with
its hedging activities. By buying a put the Fund has a right to sell the
underlying security at the exercise price, thus limiting the Fund's risk of
loss through a decline in the market value of the security until the put
expires. The amount of any appreciation in the value of the underlying
security will be partially offset by the amount of the premium paid for the
put option and any related transaction costs. Prior to its expiration, a put
option may be sold in a closing sale transaction; profit or loss from the sale
will depend on whether the amount received is more or less than the premium
paid for the put option plus the related transaction costs. A closing sale
transaction cancels out the Fund's position as the purchaser of an option by
means of an offsetting sale of an identical option prior to the expiration of
the option it has purchased. In certain circumstances, the Fund may purchase
call options on securities held in its portfolio on which it has written call
options or on securities that it intends to purchase. The Fund will not
purchase options on securities if, as a result of such purchase, the aggregate
cost of all outstanding options on securities held by the Fund would exceed 5%
of the market value of the Fund's total assets.
 
                                      18
<PAGE>
 
  Financial Futures Contracts and Options. The Fund is authorized to purchase
and sell certain financial futures contracts and options thereon solely for
the purpose of hedging its investments in Florida Municipal Bonds and
Municipal Bonds against declines in value and to hedge against increases in
the cost of securities it intends to purchase. A financial futures contract
obligates the seller of a contract to deliver and the purchaser of a contract
to take delivery of the type of financial instrument covered by the contract
or, in the case of index-based futures contracts, to make and accept a cash
settlement, at a specific future time for a specified price. 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.
 
  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 equal to approximately
5% of the contract amount must be deposited with the broker. This amount is
known as initial margin. Subsequent payments to and from the broker, called
variation margin, are made on a daily basis as the price of the financial
futures contract fluctuates making the long and short positions in the
financial futures contract more or less valuable.
 
  The Fund may purchase and sell financial futures contracts based on The Bond
Buyer Municipal Bond Index, a price-weighted measure of the market value of 40
large tax-exempt issues, and purchase and sell put and call options on such
financial futures contracts for the purpose of hedging Florida Municipal Bonds
and Municipal Bonds that the Fund holds or anticipates purchasing against
adverse changes in interest rates. The Fund also may purchase and sell
financial futures contracts on U.S. Government securities and purchase and
sell put and call options on such financial futures contracts for such hedging
purposes. With respect to U.S. Government securities, currently there are
financial futures contracts based on long-term U.S. Treasury bonds, U.S.
Treasury notes, GNMA Certificates and three-month U.S. Treasury bills.
 
  Subject to policies adopted by the Board of Trustees, the Fund also may
engage in transactions in other financial futures contracts, such as financial
futures contracts on other municipal bond indices that may become available,
if the Investment Adviser should determine that there is normally sufficient
correlation between the prices of such financial futures contracts and the
Florida Municipal Bonds and Municipal Bonds in which the Fund invests to make
such hedging appropriate.
 
  Over-The-Counter Options. The Fund may engage in options and futures
transactions on exchanges and in the over-the-counter markets ("OTC options").
In general, exchange-traded contracts are third-party contracts (i.e.,
performance of the parties' obligations is guaranteed by an exchange or
clearing corporation) with standardized strike prices and expiration dates.
OTC options transactions are two-party contracts with prices and terms
negotiated by the buyer and seller. See "Restrictions on OTC Options" below
for information as to restrictions on the use of OTC options.
 
  Restrictions on OTC Options. The Fund will engage in transactions in OTC
options only with banks or dealers that have capital of at least $50 million
or whose obligations are guaranteed by an entity having capital of at least
$50 million. Certain OTC options and assets used to cover OTC options written
by the Fund may be considered to be illiquid. The illiquidity of such options
or assets may prevent a successful sale of such options or assets, result in a
delay of sale, or reduce the amount of proceeds that might otherwise be
realized.

  Risk Factors in Options and Futures Transactions. Utilization of futures
transactions involves the risk of imperfect correlation in movements in the
price of financial futures contracts and movements in the price of the
security that is the subject of the hedge. If the price of the financial
futures contract moves more or less than the price of the security that is the
subject of the hedge, the Fund will experience a gain or loss that will not be
completely offset by movements in the price of such security. There is a risk
of imperfect correlation where the securities underlying financial futures
contracts have different maturities, ratings, geographic compositions or other
characteristics than the security being hedged. In addition, the correlation
may be affected by additions to or deletions from the index that serves as a
basis for a financial futures contract. Finally, in the case of financial
futures contracts on U.S. Government securities and options on such financial
futures contracts, the anticipated correlation of price movements between the
U.S. Government securities underlying the futures or options and Florida
Municipal Bonds and Municipal Bonds may be adversely affected by economic,
political, legislative or other developments that have a disparate impact on
the respective markets for such securities.
 
  Under regulations of the Commodity Futures Trading Commission ("CFTC"), the
futures trading activities described herein will not result in the Fund being
deemed a "commodity pool," as defined under such regulations, provided that
the Fund adheres to certain restrictions. In particular, the Fund may purchase
and sell financial futures contracts and options thereon (i) for bona fide
hedging purposes, without regard to the percentage of the Fund's assets
committed to margin and option premiums, and (ii) for non-hedging purposes if,
immediately thereafter, the sum of the amount of initial margin deposits on
the Fund's existing futures positions and option premiums entered into for
non-hedging purposes does not exceed 5% of the market value of the liquidation
value of the Fund's portfolio, after taking into account unrealized profits
and unrealized losses on any such transactions. Margin deposits may consist of
cash or securities acceptable to the broker and the relevant contract market.
 
  When the Fund purchases a financial futures contract, or writes a put option
or purchases a call option thereon, it will maintain an amount of cash, cash
equivalents (e.g., 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 financial futures
contract, thereby ensuring that the use of such financial futures contract is
unleveraged.
 
  Certain risks are involved in options and futures transactions. The
Investment Adviser believes, however, that, because the Fund will engage in
options and futures transactions only for hedging purposes, the Fund's options
and futures portfolio strategies will not subject the Fund to those risks
associated with speculation in options and futures transactions.
 
  The volume of trading in the exchange markets with respect to Florida
Municipal Bond or Municipal Bond options may be limited, and it is impossible
to predict the amount of trading interest that may exist in such options. In
addition, there can be no assurance that viable exchange markets will continue
to be available.
 
  The Fund intends to enter into options and futures transactions, on an
exchange or in the over-the-counter market, only if there appears to be a
liquid secondary market for such options or futures. There can be no
assurance, however, that a liquid secondary market will exist at any specific
time. Thus, it may not be possible to close an options or futures transaction.
The inability to close options and futures positions also could have an
adverse impact on the Fund's ability to effectively hedge its portfolio. There
is also the risk of loss by the Fund of margin deposits or collateral in the
event of bankruptcy of a broker with which the Fund has an open position in an
option or financial futures contract.
 
                                      20
<PAGE>
 
  The liquidity of a secondary market in a financial futures contract may be
adversely affected by "daily price fluctuation limits" established by
commodity exchanges that limit the amount of fluctuation in a financial
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.
 
  If it is not possible to close a financial futures position entered into by
the Fund, the Fund would continue to be required to make daily cash payments
of variation margin in the event of adverse price movements. In such a
situation, if the Fund has insufficient cash, it may have to sell portfolio
securities to meet daily variation margin requirements at a time when it may
be disadvantageous to do so.
 
  The successful use of these transactions 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 these rates remain
stable during the period in which a financial futures contract is held by the
Fund or move in a direction opposite to that anticipated, the Fund may realize
a loss on the hedging transaction that 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. Furthermore, the Fund will only engage in hedging transactions
from time to time and may not necessarily be engaged in hedging transactions
when movements in interest rates occur.
 
                 RISKS AND SPECIAL CONSIDERATIONS OF LEVERAGE
 
EFFECTS OF LEVERAGE
 
  Within approximately three months after the completion of this offering, the
Fund intends to offer shares of preferred shares representing approximately
40% of the Fund's capital immediately after the issuance of such preferred
shares. There can be no assurance, however, that preferred shares representing
such percentage of the Fund's capital will actually be issued. Issuing the
preferred shares will result in the leveraging of the common shares. Although
the Fund's Board of Trustees has not yet determined the terms of the preferred
shares offering, the Fund anticipates that the preferred shares will pay
dividends that will be adjusted over either relatively short-term periods
(generally seven 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 shares
offering will be invested in longer-term obligations in accordance with the
Fund's investment objective. The expenses of the preferred shares, which will
be borne by the Fund, will reduce the net asset value of the common shares.
Additionally, under certain circumstances, when the Fund is required to
allocate taxable income to holders of preferred shares, the Fund anticipates
that the terms of the preferred shares 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 and such additional
distribution (an "Additional Distribution"). Because under normal market
conditions, obligations with longer maturities produce higher yields than
short-term and medium-term obligations, the Investment Adviser believes that
the 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 shares and the longer-term rates received by the Fund may provide
holders of common shares with a potentially higher yield.
 
  The use of leverage, however, involves certain risks to the holders of
common shares. For example, issuance of the preferred shares may result in
higher volatility of the net asset value of the common shares and potentially
 
                                      21
<PAGE>
 
more volatility in the market value of the common shares. In addition, changes
in the short-term and medium-term dividend rates on, and the amount of taxable
income allocable to, the preferred shares will affect the yield to holders of
common shares. Leverage will allow holders of common shares to realize a
higher current rate of return than if the Fund were not leveraged as long as
the Fund, while accounting for its costs and operating expenses, is able to
realize a higher net return on its investment portfolio than the then current
dividend rate (and any Additional Distribution) of the preferred shares.
Similarly, since a pro rata portion of the Fund's net realized capital gains
are generally payable to holders of common shares, the effect of leverage will
be to increase the amount of such gains distributed to holders of common
shares. 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. To the extent that the current dividend rate (and any Additional
Distribution) on the preferred shares approaches the net return on the Fund's
investment portfolio, the benefit of leverage to holders of common shares will
be decreased. If the current dividend rate (and any Additional Distribution)
on the preferred shares were to exceed the net return on the Fund's portfolio,
holders of common shares would receive a lower rate of return than if the Fund
were not leveraged. Similarly, since both the cost of issuing the preferred
shares and any decline in the value of the Fund's investments (including
investments purchased with the proceeds from any preferred share offering)
will be borne entirely by holders of common shares, the effect of leverage in
a declining market would result in a greater decrease in net asset value to
holders of common shares than if the Fund were not leveraged. If the Fund is
liquidated, holders of preferred shares will be entitled to receive
liquidating distributions before any distribution is made to holders of common
shares.
 
  In an extreme case, a decline in net asset value could affect the Fund's
ability to pay dividends on the common shares. Failure to make such dividend
payments could adversely affect the Fund's qualification as a regulated
investment company under Federal tax laws. See "Taxes." However, the Fund
intends to take all measures necessary to make common shares dividend
payments. If the Fund's current investment income is ever insufficient to meet
dividend payments on either the common shares or the preferred shares, the
Fund may have to liquidate certain of its investments. In addition, the Fund
will have the authority to redeem the preferred shares for any reason and may
redeem all or part of the preferred shares under the following circumstances:
 
  . if the Fund anticipates that the leveraged capital structure will result
    in a lower rate of return for any significant amount of time to holders
    of the common shares than that obtainable if the common shares were not
    leveraged,
 
  . if the asset coverage for the preferred shares declines below 200% either
    as a result of a decline in the value of the Fund's portfolio investments
    or as a result of the repurchase of common shares in tender offers, or
 
  . in order to maintain the asset coverage guidelines established by the
    NRSROs that have rated the preferred shares.
 
Redemption of the preferred shares or insufficient investment income to make
dividend payments, may reduce the net asset value of the common shares and
require the Fund to liquidate a portion of its investments at a time when it
may be disadvantageous, in the absence of such extraordinary circumstances, to
do so.
 
  As discussed under "Investment Advisory and Management Arrangements," during
periods when the Fund has preferred shares outstanding, the fees paid the
Investment Adviser for investment advisory and management
 
                                      22
<PAGE>
 
services will be higher than if the Fund did not issue preferred shares
because the fees paid will be calculated on the basis of the Fund's average
weekly net assets, including proceeds from the sale of preferred shares.
 
  Assuming the use of leverage by issuing preferred shares (paying dividends
at a rate that generally will be adjusted every 28 days) in an amount
representing approximately 40% of the Fund's capital at an annual dividend
rate of     % payable on such preferred shares 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
    %.
 
  The following table is designed to illustrate the effect on the return to a
holder of the Fund's common shares of the leverage obtained by the issuance of
preferred shares representing approximately 40% 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
shareholders 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.

  Leveraging the common shares cannot be fully achieved until preferred shares
are issued and the proceeds of such offering have been invested in long-term
Florida Municipal Bonds and Municipal Bonds.
 
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 shares as noted above (or in anticipation of such changes),
the Fund may attempt to shorten the average maturity 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 shares pursuant to the Fund's Certificate of Designation, which
establishes the rights and preferences of the preferred shares, or otherwise
by purchasing preferred shares. Purchases and redemptions of preferred shares,
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 shareholders to redeem or repurchase
outstanding preferred shares, the Trustees will take into account a variety of
factors, including the following:
 
  . market conditions,
 
  . the ratio of preferred shares to common shares, and
 
  . the expenses associated with such redemption or repurchase.
 
If market conditions subsequently change, the Fund may sell previously
unissued preferred shares or preferred shares that the Fund had issued but
later repurchased or redeemed.
 
  The Fund intends to apply for ratings of the preferred shares from one or
more NRSROs. 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
 
                                      23
<PAGE>
 
from managing the Fund's portfolio in accordance with the Fund's investment
objective and policies. Ratings on the preferred shares 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 preferred shares
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 shares (expected to equal the original purchase price of the
outstanding preferred shares 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 shares 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 such liquidation value. Under the Fund's
proposed capital structure, assuming the sale of preferred shares representing
approximately 40% of the Fund's capital, the net asset value of the Fund's
portfolio is expected to be approximately 250% of the liquidation value of the
Fund's preferred shares. To the extent possible, the Fund intends to purchase
or redeem preferred shares from time to time to maintain coverage of preferred
shares of at least 200%.
 
                            INVESTMENT RESTRICTIONS
 
  The following are fundamental investment restrictions of the Fund and, prior
to issuance of the preferred shares, may not be changed without the approval
of the holders of a majority of the Fund's outstanding common shares (which
for this purpose and under the 1940 Act means the lesser of (i) 67% of the
common shares represented at a meeting at which more than 50% of the
outstanding common shares are represented or (ii) more than 50% of the
outstanding shares). Subsequent to the issuance of the preferred shares, the
following investment restrictions may not be changed without the approval of a
majority of the outstanding common shares and of the outstanding preferred
shares, voting together as a class, and the approval of a majority of the
outstanding preferred shares, 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;
  provided that the Fund may invest in securities secured by real estate or
  interests therein or issued by entities that invest in real estate or
  interest therein, and the Fund may purchase and sell financial futures
  contracts and options thereon.
 
    3. Issue senior securities or borrow money except as permitted by Section
  18 of the 1940 Act.
 
    4. Underwrite securities of other issuers except insofar as the Fund may
  be deemed an underwriter under the Securities Act of 1933, as amended, in
  selling portfolio securities.
 
    5. Make loans to other persons, except that the Fund may purchase Florida
  Municipal Bonds, Municipal Bonds and other debt securities and enter into
  repurchase agreements in accordance with its investment objective, policies
  and limitations.
 
    6. Invest more than 25% of its total assets (taken at market value at the
  time of each investment) in securities of issuers in a single industry;
  provided that, for purposes of this restriction, states, municipalities and
  their political subdivisions are not considered to be part of any industry.
 
  Additional investment restrictions adopted by the Fund, which may be changed
by the Board of Trustees without shareholder 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
 
                                      24
<PAGE>
 
  other investment companies except if immediately thereafter not more than
  (i) 3% of the total outstanding voting shares of such company is owned by
  the Fund, (ii) 5% of the Fund's total assets, taken at market value, would
  be invested in any one such company, (iii) 10% of the Fund's total assets,
  taken at market value, would be invested in such securities, and (iv) the
  Fund, together with other investment companies having the same investment
  adviser and companies controlled by such companies, owns not more than 10%
  of the total outstanding shares of any one closed-end investment company.
 
    b. Mortgage, pledge, hypothecate or in any manner transfer, as security
  for indebtedness, any securities owned or held by the Fund except as may be
  necessary in connection with borrowings mentioned in investment restriction
  (3) above or except as may be necessary in connection with transactions in
  financial futures contracts and options thereon.
 
    c. Purchase any securities on margin, except that the Fund may obtain
  such short-term credit as may be necessary for the clearance of purchases
  and sales of portfolio securities (the deposit or payment by the Fund of
  initial or variation margin in connection with financial futures contracts
  and options thereon is not considered the purchase of a security on
  margin).
 
    d. Make short sales of securities or maintain a short position or invest
  in put, call, straddle or spread options, except that the Fund may write,
  purchase and sell options and futures on Florida Municipal Bonds, Municipal
  Bonds, U.S. Government obligations and related indices or otherwise in
  connection with bona fide hedging activities and may purchase and sell Call
  Rights to require mandatory tender for the purchase of related Florida
  Municipal Bonds and Municipal Bonds.
 
  If a percentage restriction on investment policies or the investment or use
of assets set forth above is adhered to at the time a transaction is effected,
later changes in percentages resulting from changing values will not be
considered a violation.
 
  The Investment Adviser of the Fund and Merrill Lynch, Pierce, Fenner & Smith
Incorporated ("Merrill Lynch") are owned and controlled by Merrill Lynch & Co.
("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. An exemptive order has been obtained that permits the Fund to
effect principal transactions with Merrill Lynch in high quality, short-term,
tax-exempt securities subject to conditions set forth in such order. The Fund
may consider in the future requesting an order permitting other principal
transactions with Merrill Lynch, but there can be no assurance that such
application will be made and, if made, that such order would be granted.

                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 management services. The Merrill Lynch
Asset Management Group (which includes 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
     1998, the Asset Management Group had a total of approximately $
billion in investment company and other portfolio assets under management
(approximately $   billion of which was invested in municipal securities).
This amount includes assets managed for certain affiliates of the Investment
Adviser. The Investment Adviser is a limited partnership, the partners of
which are ML & Co. and Princeton Services, Inc. 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 Board of Trustees of the Fund, 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 Trustees.
 
  The Investment Adviser provides the portfolio management for the Fund. Such
portfolio management will consider analyses from various sources (including
brokerage firms with which the Fund does business), make the necessary
investment decisions, and place orders for transactions accordingly. The
Investment Adviser will also be responsible for the performance of certain
administrative and management services for the Fund.         and        are
the portfolio managers of the Fund and are primarily responsible for the
Fund's day-to-day management.
 
  For the services provided by the Investment Adviser under the Investment
Advisory Agreement, the Fund will pay a monthly fee at an annual rate of 1% of
the Fund's average weekly net assets (i.e., the average weekly value of the
total assets of the Fund, including proceeds from the issuance of preferred
shares, minus the sum of accrued liabilities of the Fund and accumulated
dividends on the preferred shares). For purposes of this calculation, average
weekly net assets are determined at the end of each month on the basis of the
average net assets of the Fund for each week during the month. The assets for
each weekly period are determined by averaging the net assets at the last
business day of a week with the net assets at the last business day of the
prior week.
 
  The 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 Trustees 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
printing proxies, listing fees, if any, share certificates and shareholder
reports, charges of the custodian and the transfer and dividend disbursing
agent and registrar, fees and expenses with respect to the issuance of
preferred shares, Securities and Exchange Commission fees, fees and expenses
of non-affiliated Trustees, 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. Accounting services
are provided to the Fund by the Investment Adviser, and the Fund reimburses
the Investment Adviser for its costs in connection with such services.
 
                                      28

  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 Trustees of the Fund or by a majority of the
outstanding shares of the Fund and (b) by a majority of the Trustees 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 shareholders of the Fund.
 
  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
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 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.
 
CODE OF ETHICS
 
  The Board of Trustees of the Fund has adopted a Code of Ethics pursuant to
Rule 17j-1 under the 1940 Act that incorporates the Code of Ethics of the
Investment Adviser (together, the "Codes"). The Codes significantly restrict
the personal investing activities of all employees of the Investment Adviser
and, as described below, impose additional, more onerous, restrictions on Fund
investment personnel.
 
  The Codes require that all employees of the Investment Adviser preclear any
personal securities investment (with limited exceptions, such as U.S.
Government securities). The preclearance requirement and associated procedures
are designed to identify any substantive prohibition or limitation applicable
to the proposed investment. The substantive restrictions applicable to all
employees of the Investment Adviser include a ban on acquiring any securities
in a "hot" initial public offering and a prohibition from profiting on short-
term trading securities. In addition, no employee may purchase or sell any
security that at the time is being purchased or sold (as the case may be), or
to the knowledge of the employee is being considered for purchase or sale, by
any fund advised by the Investment Adviser. Furthermore, the Codes provide for
trading "blackout periods" that prohibit trading by investment personnel of
the Fund within periods of trading by the Fund in the same (or equivalent)
security (15 or 30 days depending upon the transaction).
 
                            PORTFOLIO TRANSACTIONS
 
  Subject to policies established by the Board of Trustees of the Fund, the
Investment Adviser is primarily responsible for the execution of the Fund's
portfolio transactions. In executing such transactions, the Investment Adviser
seeks to obtain the best results for the Fund, taking into account such
factors as price (including the applicable brokerage commission or dealer
spread), size of order, difficulty of execution and operational facilities of
the firm involved and the firm's risk in positioning a block of securities.
While the Investment Adviser generally seeks reasonably competitive commission
rates, the Fund does not necessarily pay the lowest commission or spread
available.
 
                                      29
<PAGE>
 
  The Fund has no obligation to deal with any broker or dealer in the
execution of transactions in portfolio securities. Subject to providing the
best price and execution, securities firms that provide supplemental
investment research to the Investment Adviser, including Merrill Lynch, may
receive orders for transactions by the Fund. Research information provided to
the Investment Adviser by securities firms is supplemental. It does not
replace or reduce the level of services performed by the Investment Adviser
and the expenses of the Investment Adviser will not be reduced because it
receives supplemental research information.
 
  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 prices and
execution are 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 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, serve as its brokers in certain over-the-counter transactions
conducted on an agency basis.
 
  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.
 
PORTFOLIO TURNOVER
 
  The Fund may dispose of securities without regard to the time they have been
held when such action, for defensive or other reasons, if it appears advisable
to the Investment Adviser. While it is not possible to predict turnover rates
with any certainty, presently it is anticipated that the Fund's annual
portfolio turnover rate, under normal circumstances, should be less than 100%.
(The portfolio turnover rate is calculated by dividing the lesser of purchases
or sales of portfolio securities for the particular fiscal year by the monthly
average of the value of the portfolio securities owned by the Fund during the
particular fiscal year. For purposes of determining this rate, all securities
whose maturities at the time of acquisition are one year or less are
excluded.) A high portfolio turnover rate bears certain tax consequences and
results in greater transaction costs, which are borne directly by the Fund.
 
                          DIVIDENDS AND DISTRIBUTIONS
 
  The Fund intends to distribute all its net investment income. Dividends from
such net investment income will be declared and paid monthly to holders of
common shares. It is expected that the Fund will commence paying dividends to
holders of common shares within approximately 90 days of the date of this
prospectus. From and after issuance of the preferred shares, monthly
distributions to holders of common shares normally will consist of
substantially all net investment income remaining after the payment of
dividends (and any Additional Distribution) on the preferred shares. All net
realized capital gains, if any, will be distributed pro rata at least annually
to holders of common shares and any preferred shares. While any preferred
shares are outstanding, the Fund may not declare any cash dividend or other
distribution on its common shares, unless at the time of such declaration, (i)
all accumulated preferred share dividends, including any Additional
Distribution, have been paid,
 
                                      30
<PAGE>
 
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 shares (expected to
equal the original purchase price of the outstanding preferred shares plus any
accumulated and unpaid dividends thereon and any accumulated but unpaid
Additional Distribution). If the Fund's ability to make distributions on its
common shares 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
holders of common shares. See "Taxes."
 
  See "Automatic Dividend Reinvestment Plan" for information concerning the
manner in which dividends and distributions to holders of common shares may be
automatically reinvested in common shares of the Fund. Dividends and
distributions may be taxable to shareholders under certain circumstances as
discussed below, whether they are reinvested in shares of the Fund or received
in cash.
 
                                     TAXES
 
GENERAL
 
  The Fund intends to elect and to qualify for the special tax treatment
afforded regulated investment companies ("RICs") under the Internal Revenue
Code of 1986, as amended (the "Code"). As long as it so qualifies, in any
taxable year in which it distributes at least 90% of its taxable net income
and 90% of its tax-exempt net income (see below), the Fund (but not its
shareholders) 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 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 exempt from Federal income tax ("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 shareholders. 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
shareholders within 60 days after the close of its taxable year. To the extent
that the dividends distributed to the Fund's shareholders are derived from
interest income exempt from tax under Code Section 103(a) and are properly
designated as exempt-interest dividends, they will be excludable from a
shareholder'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 shareholder is advised to consult a tax adviser with
respect to whether exempt-interest dividends retain the exclusion under Code
Section 103(a) if such shareholder
 
                                      31
<PAGE>
 
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 "industrial development bonds" or "private activity bonds," if any, held by
the Fund.
 
  The Fund has applied for a ruling from the Florida Department of Revenue
that shares of the Fund will be exempt from Florida intangible personal
property tax in the following year, if, on the last business day of any
calendar year, the Fund's assets consist solely of assets exempt from Florida
intangible personal property tax ("asset requirement"). Although there is no
assurance that the Florida Department of Revenue will issue a favorable ruling
on this issue, the Florida Department of Revenue has previously issued similar
rulings. The Florida Department of Revenue has the authority to revoke or
modify a previously issued ruling; however, if a ruling is revoked or
modified, the revocation or modification is prospective only. Prior to receipt
of the ruling from the Florida Department of Revenue, the Fund will rely on an
opinion of Florida counsel for the Fund, Holland & Knight LLP, stating that
Fund shares will be exempt from Florida intangible personal property tax if
the asset requirement is met. This opinion is based on existing Florida law
and interpretive authority which could be changed at any time retroactively.
While the opinion represents the best judgment of Holland & Knight LLP, the
legal conclusions reached therein are not binding on the Florida Department of
Revenue, and there is no assurance that the legal conclusions will not be
challenged by the Department of Revenue or in judicial or administrative
proceedings. Thus, under Florida counsel's opinion or if a favorable ruling is
issued, and if the asset requirement is met, shares of the Fund owned by
Florida residents will be exempt from Florida intangible personal property
tax. Assets exempt from Florida intangible personal property tax include
Florida Municipal Bonds, obligations of the United States Government or its
agencies, and cash.
 
  The Fund may from time to time hold assets that are not exempt from Florida
intangible personal property tax. It is possible that the Fund may not be able
to fully dispose of all of its assets subject to Florida intangible personal
property tax by the last business day of the calendar year. This would subject
shares of the Fund to Florida intangible personal property tax. If shares of
the Fund are subject to Florida intangible personal property tax because the
asset requirement is not met, only that portion of the value of Fund shares
equal to the portion of the net asset value of the Fund that is attributable
to obligations of the United States Government will be exempt from taxation.
The Fund will attempt to monitor its portfolio so that on the last business
day of each calendar year the Fund's assets consist solely of assets exempt
from Florida intangible personal property tax.
 
  Dividends paid by the Fund to individuals who are Florida residents are not
subject to personal income taxation by Florida, because Florida does not
impose a personal income tax. Distributions of investment income and capital
gains by the Fund will be subject to Florida corporate income taxes, state
taxes in states other than Florida and local taxes in cities other than those
in Florida. Shareholders not subject to taxation by Florida do not benefit
from the fact that shares of the Fund will be exempt from the Florida
intangible personal property tax. Interest on indebtedness incurred or
continued to purchase or carry Fund shares is not deductible for Federal
income tax purposes to the extent attributable to exempt-interest dividends.
 
  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
will be 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 shareholder has owned Fund shares. Certain
 
                                      32
<PAGE>
 
categories of capital gains are taxable at different rates. Generally not
later than 60 days after the close of its taxable year, the Fund will provide
its shareholders with a written notice designating the amounts of any exempt-
interest dividends, ordinary income dividends or capital gain dividends, as
well as any amount of capital gain dividends in the different categories of
capital gain referred to above. 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 shareholders. 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). 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 shareholder. 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 shareholder.
If the Fund pays a dividend in January that was declared in the previous
October, November or December to shareholders 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 shareholders on December 31 of the
year in which such dividend was declared.
 
  The Internal Revenue Service (the "Service") has taken the position in a
revenue ruling that if a RIC has more than one class 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 shares and one or more series of
preferred shares are outstanding, the Fund intends to designate distributions
made to the classes as consisting of particular types of income in accordance
with the classes' proportionate shares 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 shares and series of
preferred shares 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 shares pursuant to the allocation rules
described above, the terms of the preferred shares 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 an alternative minimum tax. The alternative minimum tax will
apply 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 generally 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" that could subject certain investors
in such bonds, including shareholders of the Fund, to an increased alternative
minimum tax. The Fund intends to purchase such "private activity bonds" and
will report to shareholders within 60 days after calendar year-end the portion
of its dividends declared during the year that constitutes an item of tax
preference for alternative minimum tax purposes. The Code further provides
that
 
                                      33
<PAGE>
 
corporations are subject to an 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 shareholder may be required to pay an 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.
 
  If at any time when preferred shares 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 shares 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. Upon any failure to
meet the asset coverage requirements of the 1940 Act, the Fund, in its sole
discretion, may redeem preferred shares in order to maintain or restore the
requisite asset coverage and avoid the adverse consequences to the Fund and
its shareholders 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 shares that the Fund currently contemplates
issuing may raise an issue as to whether distributions on such preferred
shares are "preferential" under the Code and, therefore, not eligible for the
dividends paid deduction. The Fund intends to issue preferred shares that
counsel advises will not result in the payment of a preferential dividend and
may seek a private letter ruling from the Service to that effect. If the Fund
ultimately relies solely on a legal opinion when it issues such preferred
shares, there is no assurance that the Service would agree that dividends on
the preferred shares are not preferential. If the Service successfully
disallowed the dividends paid deduction for dividends on the preferred shares,
the Fund could be disqualified as a RIC. In this case, dividends on the common
shares would not be exempt from Federal income taxes. Additionally, the Fund
would be subject to the 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 shareholders,
including shareholders who do not participate in the dividend reinvestment
plan. Thus, shareholders 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.
 
  Ordinary income dividends paid to shareholders who are nonresident aliens or
foreign entities will be subject to a 30% United States withholding tax under
existing provisions of the Code applicable to foreign
 
                                      34
<PAGE>
 
individuals and entities unless a reduced rate of withholding or a withholding
exemption is provided under applicable treaty law. Nonresident shareholders
are urged to consult their own tax advisers concerning the applicability of
the United States withholding tax.
 
  Under certain Code provisions, some taxpayers may be subject to 31%
withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
shareholders subject to backup withholding are those for whom no certified
taxpayer identification number is on file with the Fund or who, to the Fund's
knowledge, have furnished an incorrect number. When establishing an account,
an investor must certify under penalty of perjury that such number is correct
and that such investor is not otherwise subject to backup withholding.
 
  The Code provides that every shareholder required to file a tax return must
include for information purposes on such return the amount of exempt-interest
dividends received from all sources (including the Fund) during the taxable
year.
 
TAX TREATMENT OF OPTIONS AND FUTURES TRANSACTIONS
 
  The Fund may purchase or sell municipal bond index financial futures
contracts and interest rate financial futures contracts on U.S. Government
securities. The Fund may also purchase and write call and put options on such
financial futures contracts. In general, unless an election is available to
the Fund or an exception applies, such options and financial futures contracts
that are "Section 1256 contracts" will be "marked to market" for Federal
income tax purposes at the end of each taxable year, i.e., each such option or
financial futures contract will be treated as sold for its fair market value
on the last day of the taxable year, and any gain or loss attributable to
Section 1256 contracts will be 60% long-term and 40% short-term capital gain
or loss. Application of these rules to Section 1256 contracts held by the Fund
may alter the timing and character of distributions to shareholders. The mark-
to-market rules outlined above, however, will not apply to certain
transactions entered into by the Fund solely to reduce the risk of changes in
price or interest rates with respect to its investments.
 
  Code Section 1092, which applies to certain "straddles," may affect the
taxation of the Fund's sales of securities and transactions in financial
futures contracts and related options. Under Section 1092, the Fund may be
required to postpone recognition for tax purposes of losses incurred in
certain sales of securities and certain closing transactions in financial
futures contracts or the related options.
 
FLORIDA TAXATION OF THE FUND
 
  If the Fund does not have a taxable nexus to Florida, such as through the
location within the state of the Fund's activities or those of the Investment
Adviser, under present Florida law, the Fund is not subject to Florida
corporate income taxation. Additionally, if the Fund's assets do not have a
taxable situs in Florida on January 1 of each calendar year, the Fund will not
be subject to Florida intangible personal property tax. If the Fund has a
taxable nexus to Florida or the Fund's assets have a taxable situs in Florida
on January 1 of any year, the Fund will be subject to Florida taxation.
 
                               ----------------
 
                                      35
<PAGE>
 
  The foregoing is a general and abbreviated summary of the applicable
provisions of the Code and Treasury Regulations and Florida tax laws presently
in effect. For the complete provisions, reference should be made to the
pertinent Code sections, the Treasury Regulations promulgated thereunder and
Florida tax laws. The Code and the Treasury Regulations, as well as the
Florida tax laws, are subject to change by legislative, judicial or
administrative action either prospectively or retroactively.
 
  Shareholders 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 holder of common shares otherwise elects, all dividend and capital
gains distributions will be automatically reinvested by
    , as agent for shareholders in administering the Plan (the "Plan Agent"),
in additional common shares of the Fund. Holders of common shares who elect
not to participate in the Plan will receive all distributions in cash paid by
check mailed directly to the shareholder of record (or, if the shares are held
in street or other nominee name, then to such nominee) by          , as
dividend paying agent. Such participants 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          , 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 or resumption will be effective with respect
to any subsequently declared dividend or distribution.
 
  Whenever the Fund declares an income dividend or a capital gains
distribution (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 common shares. The
shares will be acquired by the Plan Agent for the participant's account,
depending upon the circumstances described below, either (i) through receipt
of additional unissued but authorized common shares from the Fund ("newly
issued shares") or (ii) by purchase of outstanding common shares on the open
market ("open-market purchases") on the New York Stock Exchange (the "NYSE")
or elsewhere. If on the payment date for the dividend, the net asset value per
share of the common shares is equal to or less than the market price per
common shares 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 shares 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. Prior to the time the common shares commence trading on
the NYSE, participants in the Plan will receive any dividends in newly issued
shares.
 
  In the event of a market discount on the dividend payment date, the Plan
Agent will have 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.
 
                                      36
<PAGE>
 
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 common share exceeds the net asset value per share, the average per
share purchase prices 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 shareholders' accounts in the Plan and
furnishes written confirmation of all transactions in the account, including
information needed by shareholders 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 shareholder'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 shareholders such as banks, brokers or nominees that 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 shareholders as representing the total amount registered
in the record shareholder'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."
 
  Shareholders participating in the Plan may receive benefits not available to
shareholders not participating in the Plan. If the market price plus
commissions of the Fund's shares is above 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 will receive
distributions in 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. See
"Taxes" for a discussion of tax consequences of the Plan.
 
  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                 .

                         MUTUAL FUND INVESTMENT OPTION
 
  Purchasers of common shares of the Fund through Merrill Lynch 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 D
initial sales charge shares of certain Merrill Lynch-sponsored open-end mutual
funds ("Eligible Class D 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 the Original Shares must be made through Merrill
Lynch, and the net proceeds therefrom must be immediately reinvested in
Eligible Class D Shares. Second, the Original Shares must have been either
acquired in this offering or be shares representing reinvested dividends from
common shares acquired in this offering. Third, the Original Shares must have
been continuously maintained in a Merrill Lynch securities account. Fourth,
there must be a minimum purchase of $250 to be eligible for the investment
option. Class D shares of the mutual funds are subject to an account
maintenance fee at an annual rate of up to 0.25% of the average daily net
asset value of such mutual fund. The Eligible Class D Shares may be redeemed
at any time at the next determined net asset value, subject in certain cases
to a redemption fee. Prior to the time the common shares commence trading on
the NYSE, the distributor for the mutual funds will advise Merrill Lynch
Financial Consultants as to those mutual funds that offer the investment
option described above.
 
                                NET ASSET VALUE
 
  Net asset value per common share is determined as of 15 minutes after the
close of business on the NYSE (generally, the NYSE closes at 4:00 p.m.,
Eastern time) on the last business day in each week. For purposes of
determining the net asset value of a common share, 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 the outstanding preferred shares is divided by
the total number of common shares outstanding at such time. Expenses,
including the fees payable to the Investment Adviser, are accrued daily.
 
  The Florida Municipal Bonds and Municipal Bonds in which the Fund invests
are traded primarily in the over-the-counter markets. In determining net asset
value, the Fund utilizes the valuations of portfolio securities furnished by a
pricing service approved by the Board of Trustees. The pricing service
typically values portfolio securities at the bid price or the yield equivalent
when quotations are readily available. Florida Municipal Bonds and 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 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 Trustees. The Board of Trustees 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 are
valued at closing prices for such contracts established by the exchange on
which they are traded, or if market quotations are not readily available, are
valued at fair value on a consistent basis using methods determined in good
faith by the Board of Trustees.
 
  The Fund determines and makes available for publication the net asset value
of its common shares weekly. 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.

                         DESCRIPTION OF CAPITAL SHARES
 
  The Fund is authorized to issue an unlimited number of shares of beneficial
interest, par value $.10 per share. The Board of Trustees may authorize
separate classes of shares together with such designations and powers,
preferences and rights, qualifications, limitations and restrictions as may be
determined from time to time by the Trustees. Pursuant to such authority, the
Trustees have authorized the issuance of an unlimited number of common shares
together with 1,000,000 preferred shares. Within approximately three months
after completion of the offering of the common shares described herein, the
Fund intends to offer preferred shares representing approximately 40% of the
Fund's capital immediately after the issuance of such preferred shares. There
is no assurance that such preferred shares will be issued.
 
  The Fund is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of such a trust may,
under certain circumstances, be held personally liable as partners for its
obligations. However, the Declaration of Trust of the Fund contains an express
disclaimer of shareholder liability for acts or obligations of the Fund and
provides for indemnification and reimbursement of expenses out of the Fund's
property for any shareholder held personally liable for the obligations of the
Fund. Thus, the risk of a shareholder incurring financial loss on account of
shareholder liability is limited to circumstances in which the Fund itself
would be unable to meet its obligations. Given the nature of the Fund's assets
and operations, the possibility of the Fund being unable to meet its
obligations is remote and, in the opinion of Massachusetts counsel to the
Fund, the risk to Fund shareholders is remote.
 
  The Declaration of Trust further provides that no Trustee, officer, employee
or agent of the Fund is liable to the Fund or to any shareholder, nor is any
Trustee, officer, employee of agent liable to any third persons in connection
with the affairs of the Fund, except as such liability may arise from his or
her own bad faith, willful misfeasance, gross negligence, or reckless
disregard of their duties. It also provides that all third persons shall look
solely to the Fund property for satisfaction of claims arising in connection
with the affairs of the Fund. With the exceptions stated, the Declaration of
Trust provides that a Trustee, officer, employee or agent is entitled to be
indemnified against all liability in connection with the affairs of the Fund.
 
COMMON SHARES
 
  Common shares, when issued and outstanding, will be fully paid and non-
assessable. Shareholders are entitled to share pro rata in the net assets of
the Fund available for distribution to shareholders upon liquidation of the
Fund. Shareholders are entitled to one vote for each share held.
 
  So long as any shares of the Fund's preferred shares are outstanding,
holders of common shares will not be entitled to receive any net income of or
other distributions from the Fund unless all accumulated dividends on
preferred shares have been paid and unless asset coverage (as defined in the
1940 Act) with respect to preferred shares would be at least 200% after giving
effect to such distributions. See "Preferred Shares" below.
 
  The Fund will send unaudited reports at least semi-annually and audited
annual financial statements to all of its shareholders.
 
  The Investment Adviser provided the initial capital for the Fund by
purchasing 6,667 common shares of the Fund for $100,005. As of the date of
this prospectus, the Investment Adviser owned 100% of the outstanding common
shares 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.
 
                                      39

PREFERRED SHARES
 
  It is anticipated that the Fund's preferred shares will be issued in one or
more series, with rights as determined by the Board of Trustees, by action of
the Board of Trustees without the approval of the holders of common shares.
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 shares have no preemptive right to purchase any
preferred shares that might be issued. It is anticipated that the net asset
value per the preferred shares will equal its original purchase price per
share plus accumulated dividends per share.
 
  The Fund's Board of Trustees has declared its intention to authorize an
offering of preferred shares (representing approximately 40% of the Fund's
capital immediately after the issuance of such preferred shares) within
approximately three months after completion of the offering of common shares,
subject to market conditions and to the Board's continuing to believe that
leveraging the Fund's capital structure through the issuance of preferred
shares is likely to achieve the benefits to the holders of common shares
described in the prospectus. Although the terms of the preferred shares,
including its dividend rate, voting rights, liquidation preference and
redemption provisions will be determined by the Board of Trustees (subject to
applicable law and the Fund's Declaration of Trust), the initial series of
preferred shares 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 seven 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. Additionally, under certain circumstances, when the
Fund is required to allocate taxable income to holders of the preferred
shares, it is anticipated that the terms of the preferred shares will require
the Fund to make an Additional Distribution (as defined in "Risks and Special
Considerations of Leverage--Effects of Leverage") to such holders. The Board
also has indicated that it is likely that the liquidation preference, voting
rights and redemption provisions of the preferred shares will be as stated
below. The Fund's Declaration of Trust, as amended, together with any
Certificate of Designation, is referred to below as the "Charter."
 
  Liquidation Preference. In the event of any voluntary or involuntary
liquidation, dissolution or winding up of the Fund, the holders of preferred
shares 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 and any
accumulated and unpaid Additional Distribution) before any distribution of
assets is made to holders of common shares. After payment of the full amount
of the liquidating distribution to which they are entitled, the preferred
shareholders 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 preferred shares will have
equal voting rights with holders of common shares (one vote per share) and
will vote together with holders of common shares as a single class.
 
  In connection with the election of the Fund's trustees, holders of preferred
shares, voting as a separate class, will be entitled to elect two of the
Fund's trustees, and the remaining trustees will be elected by all holders of
capital shares, voting as a single class. So long as any preferred shares are
outstanding, the Fund will have not
 
                                      40
<PAGE>
 
less than five trustees. If at any time dividends on the Fund's preferred
shares shall be unpaid in an amount equal to two full years' dividends
thereon, the holders of all outstanding preferred shares, voting as a separate
class, will be entitled to elect a majority of the Fund's trustees 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
preferred shares, voting as a separate class, will be required to (i)
authorize, create or issue any class or series of shares ranking prior to any
series of preferred shares 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 shares.
 
  Redemption Provisions. It is anticipated that preferred shares 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. Preferred
shares 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
shares specified by the rating agencies that issue ratings on the preferred
shares.
 
CERTAIN PROVISIONS OF THE DECLARATION OF TRUST
 
  The Fund's Declaration of Trust 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 Trustees and could
have the effect of depriving shareholders 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 trustee may be removed
from office with or without cause, but only by vote of the holders of at least
66 2/3% of the votes entitled to be voted on the matter. A trustee elected by
all the holders of capital shares may be removed only by action of such
holders, and a trustee elected by the holders of preferred shares may be
removed only by action of such holders.
 
  In addition, the Declaration of Trust requires the favorable vote of the
holders of at least 66 2/3% of the Fund's capital shares then entitled to be
voted, voting as a single class, to approve, adopt or authorize the following:
 
    . a merger or consolidation or statutory share exchange of the Fund with
  other corporations,
 
    . 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
 
    . a liquidation or dissolution of the Fund, unless such action has been
      approved, adopted or authorized by the affirmative vote of two-thirds
      of the total number of Trustees fixed in accordance with the by-laws,
      in which case the affirmative vote of a majority of the Fund's capital
      shares is required. Following the proposed issuance of the preferred
      shares, it is anticipated that the approval, adoption or authorization
      of the foregoing would also require the favorable vote of a majority of
      the Fund's preferred shares 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 Declaration of Trust. The amendment would
have to be declared advisable by the Board of Trustees prior to its submission
to shareholders. Such an amendment would require the favorable vote of the
holders of at
 
                                      41
<PAGE>
 
least 66 2/3% of the Fund's outstanding capital shares (including any
preferred shares) 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 Trustees fixed in
accordance with the by-laws), and, assuming preferred shares are issued, the
affirmative vote of a majority of outstanding preferred shares 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 shareholders.
Shareholders of an open-end investment company may require the company to
redeem their common shares 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 shares would no longer be listed
on a stock exchange.
 
  Conversion to an open-end investment company would also require redemption
of all outstanding preferred shares and would require changes in certain of
the Fund's investment policies and restrictions, such as those relating to the
issuance of senior securities, the borrowing of money and the purchase of
illiquid securities.
 
  The Board of Trustees has determined that the 66 2/3% voting requirements
described above, which are greater than the minimum requirements under
Massachusetts law or the 1940 Act, are in the best interests of shareholders
generally. Reference should be made to the Charter on file with the Securities
and Exchange Commission for the full text of these provisions.
 
                                   CUSTODIAN
 
  The Fund's securities and cash are held under a custodial agreement with
                        .
 
                                 UNDERWRITING
 
  Merrill Lynch, Pierce, Fenner & Smith Incorporated (the "Underwriter") has
agreed, subject to the terms and conditions of a Purchase Agreement with the
Fund and the Investment Adviser, to purchase           common shares from the
Fund. The Underwriter is committed to purchase all of such shares if any are
purchased.
 
  The Underwriter has advised the Fund that it proposes initially to offer the
common shares to the public at the public offering price set forth on the
cover page of this prospectus. There is no sales charge or underwriting
discount charged to investors on purchases of common shares in the offering.
The Investment Adviser or an affiliate has agreed to pay the Underwriter from
its own assets a commission in connection with the sale of common shares in
the offering in the amount of $    per share. Such payment is equal to     %
of the initial public offering price per share. The Underwriter also has
advised the Fund that from this amount the Underwriter may pay a concession to
certain dealers not in excess of $    per share on sales by such dealers.
After the initial public offering, the public offering price and other selling
terms may be changed.  Investors must pay for common shares purchased in the
offering on or before       , 1999.
 
  The Fund has granted the Underwriter an option, exercisable for 45 days
after the date hereof, to purchase up to         additional common shares to
cover over-allotments, if any, at the initial offering price.
 
 
                                      42
<PAGE>
 
  The Underwriter may engage in certain transactions that stabilize the price
of the common shares. Such transactions consist of bids or purchases for the
purpose of pegging, fixing or maintaining the price of the common shares.
 
  If the Underwriter creates a short position in the common shares in
connection with the offering, i.e., if it sells more common shares than are
set forth on the cover page of this prospectus, the Underwriter may reduce
that short position by purchasing common shares in the open market. The
Underwriter also may elect to reduce any short position by exercising all or
part of the over-allotment option described above.
 
  The Underwriter also may impose a penalty bid on certain selling group
members. This means that if the Underwriter purchases common shares in the
open market to reduce the Underwriter's short position or to stabilize the
price of the common shares, it may reclaim the amount of the selling
concession from the selling group members who sold those common shares as part
of the offering.
 
  In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher
than it might be in the absence of such purchases. The imposition of a penalty
bid might also have an effect on the price of a security to the extent that it
were to discourage resales of the security.
 
  Neither the Fund nor the Underwriter 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 of common stock. In addition,
neither the Fund nor the Underwriter makes any representation that the
Underwriter will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
 
  Prior to this offering, there has been no public market for the common
shares. The Fund plans to apply to list its common shares on the NYSE.
However, during an initial period which is not expected to exceed two weeks
from the date of this prospectus, the Fund's common shares will not be listed
on any securities exchange. Additionally, before it begins trading, the
Underwriter does not intend to make a market in the Fund's common 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 Underwriter has undertaken to
sell lots of 100 or more shares to a minimum of 2,000 beneficial owners.
 
  The Fund anticipates that the Underwriter may from time to time act as a
broker in connection with the execution of its portfolio transactions. The
Fund has obtained an exemptive order permitting it to engage in certain
principal transactions with the Underwriter involving high quality, short-
term, tax-exempt securities subject to certain conditions. See "Investment
Restrictions" and "Portfolio Transactions."
 
  The Underwriter is an affiliate of the Investment Adviser of the Fund.
 
  The Fund and the Investment Adviser have agreed to indemnify the Underwriter
against certain liabilities, including liabilities under the Securities Act of
1933.

YEAR 2000 ISSUES
 
  Many computer systems were designed using only two digits to designate
years. These systems may not be able to distinguish the Year 2000 from the
Year 1900 (commonly known as the "Year 2000 Problem"). Like other investment
companies and financial and business organizations, the Fund could be
adversely affected if the computer systems used by the Investment Adviser or
other Fund service providers do not properly address this problem prior to
January 1, 2000. The Investment Adviser has established a dedicated group to
analyze these issues and to implement any systems modifications necessary to
prepare for the Year 2000. Currently, the Investment Adviser does not
anticipate that the transition to the Year 2000 will have any material impact
on its ability to continue to service the Fund at current levels. In addition,
the Investment Adviser has sought assurances from the Fund's other service
providers that they are taking all necessary steps to ensure that their
computer systems will accurately reflect the Year 2000, and the Investment
Adviser will continue to monitor the situation. At this time, however, no
assurance can be given that the Fund's other service providers have
anticipated every step necessary to avoid any adverse effect on the Fund
attributable to the Year 2000 Problem.

                        REPORT OF INDEPENDENT AUDITORS
 
To the Board of Trustees and Shareholder of
 MuniHoldings Florida Insured Fund IV
 
We have audited the accompanying statement of assets, liabilities and capital
of MuniHoldings Florida Insured Fund IV as of       , 1999. This statement of
assets, liabilities and capital is the responsibility of the Fund's
management. Our responsibility is to express an opinion on this statement of
assets, liabilities and capital based on our audit.
 
We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the statement of assets, liabilities
and capital is free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the statement
of assets, liabilities and capital. An audit also includes assessing the
accounting principles used and significant estimates made by management, as
well as evaluating the overall statement of assets, liabilities and capital
presentation. We believe that our audit provides a reasonable basis for our
opinion.
 
In our opinion, the statement of assets, liabilities and capital referred to
above presents fairly, in all material respects, the financial position of

</TABLE>
 
             NOTES TO STATEMENT OF ASSETS, LIABILITIES AND CAPITAL
 
NOTE 1. ORGANIZATION
 
  The Fund was organized under the laws of the Commonwealth of Massachusetts
on November 25, 1998 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 6,667 shares
for $100,005 on       , 1999. The General Partner of the Investment Adviser is
an indirectly wholly owned subsidiary of Merrill Lynch & Co., Inc.
 
  Deferred organization costs will be amortized on a straight-line basis over
a period not exceeding five years beginning with the commencement of
operations of the Fund. Direct costs relating to the public offering of the
Fund's shares will be charged to capital at the time of issuance of shares. In
accordance with Statement of Position 98-5, unamortized organization costs
existing at       , 1999 (the start of the Fund's new fiscal year), will be
charged to expense at that date. At the present time, management believes that
this charge will not have any material impact on the operations of the Fund.
 
NOTE 2. MANAGEMENT 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 at an annual rate of 0.55 of 1% of the Fund's average weekly net
assets, including proceeds from the issuance of preferred shares. The
Investment Adviser or an affiliate will pay Merrill Lynch, Pierce, Fenner &
Smith Incorporated a commission in the amount of 2.00% of the price to the
public per share in connection with the initial public offering of the Fund's
Common Shares.
 
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 shareholders.

                                  APPENDIX I
 
                   ECONOMIC AND OTHER CONDITIONS IN FLORIDA
 
  The following information is a brief summary of factors affecting the
economy of the State of Florida (the "State") and does not purport to be a
complete description of such factors. Other factors will affect issuers. The
summary is based upon one or more publicly available offering statements
relating to debt offerings of the State. The Fund has not independently
verified the information.
 
  Throughout the 1980s, the State's unemployment rate has, generally, tracked
below that of the nation. In the nineties, the trend was reversed, until 1995
and 1996, when the State's unemployment rate again tracked below the national
average. The State's unemployment rate is projected to be 4.7% in 1997-98 and
5.0 in 1998-99. The average rate of unemployment for the State was 4.8% while
the nation's was 4.9%. (The projections set forth in this Appendix were
obtained from a report, prepared by the Revenue and Economic Analysis Unit of
the Executive Office of the Governor for the State of Florida, contained
within a recent official statement, dated August 18, 1998, for a State of
Florida debt offering.)
 
  Personal income in the State has grown at a strong pace and has generally
outperformed both the nation as a whole and the Southeast in particular. From
1992 through 1997, the State's per capita income expanded approximately 25.9%,
while the national per capita income increased by 24.1%. Real personal income
in Florida is estimated to increase 5.2% in 1997-98 and 3.7% in 1998-99 while
real personal income per capita is projected to grow at 3.2% in 1997-98 and
1.8% in 1998-99.
 
  The structure of Florida's income differs from that of the nation and the
southeast. Because Florida has a proportionally greater retirement age
population, property income (dividends, interest, and rent) and transfer
payments (social security and pension benefits, among other sources of income)
are a relatively more important source of income. For example, Florida's
employment income in 1997 represented 59.8% of total personal income, while
the nation's share of total personal income in the form of wages and salaries
and other labor benefits was 70.4%. Florida's income is dependent upon
transfer payments controlled by the federal government.
 
  The State's strong population growth is one fundamental reason why its
economy has typically performed better than the nation as a whole. In 1980,
the State was ranked seventh among the 50 states with a population of 9.7
million people. The State has grown dramatically since then and as of April 1,
1997 ranked fourth with an estimated population of 14.7 million. Since 1990,
the State's average annual rate of population increase has been approximately
1.8% as compared to an approximately 1.0% for the nation as a whole. While
annual growth in the State's population is expected to decline somewhat, it is
still expected to grow close to 230,000 new residents per year throughout the
1990s.
 
  Tourism is one of the State's most important industries. 47 million people
visited the State in 1997, according to the Florida Department of Commerce.
Tourism arrivals are expected to increase by 2.1% this fiscal year and 4.7%
next year. By the end of the fiscal year, 43.8 million domestic and
international tourists are expected to have visited the State. In 1998-99,
tourist arrivals should approximate 45.6 million. Florida tourism appears to
be recovering from the effects of negative publicity regarding crime against
tourists in the state. Factors such as "product maturity" of a Florida
vacation package, higher prices, and more aggressive marketing by competing
vacation destinations, could contribute to a tourism slowdown.

  Florida's dependency on the highly cyclical construction and construction-
related manufacturing sectors has declined. For example, total contract
construction employment as a share of total non-farm employment was a little
over 5.7% in 1997. Florida, nevertheless, has had a dynamic construction
industry, with single and multi-family housing starts accounting for
approximately 9.2% of total U.S. housing starts, while the State's population
was 5.5% of the nation's population. Total housing starts were 132,813 in
1997. A driving force behind Florida's construction industry is its rapid
growth in population. In Florida, single and multi-family housing starts in
1997-98 are projected to reach a combined level of 129,500, while increasing
131,300 next year. Multi-family starts have been slow to recover, but are
showing stronger growth now and should maintain a level of nearly 38,200 in
1997-98 and 37,200 in 1998-99. Total construction expenditures are forecasted
to increase 13.2% in this year and increase 6.5% next year.
 
  Financial operations of the State covering all receipts and expenditures are
maintained through the use of four funds--the General Revenue Fund, Trust
Funds, the Working Capital Fund, and beginning in fiscal year 1994-95, the
Budget Stabilization Fund. In fiscal year 1996-97, the State derived
approximately 67% of its total direct revenues to these funds from State taxes
and fees. Federal funds and other special revenues accounted for the remaining
revenues. Major sources of tax revenues to the General Revenue Fund are the
sales and use tax, corporate income tax, intangible personal property tax,
beverage tax, and estate tax which amounted to 68%, 8%, 4% and 3%,
respectively, of total General Revenue Funds available. State expenditures are
categorized for budget and appropriation purposes by type of fund and spending
unit, which are further subdivided by line item. In fiscal year 1996-97,
expenditures from the General Revenue Fund for education, health and welfare,
and public safety amounted to approximately 53%, 26% and 14%, respectively, of
total General Revenues.
 
  The Sales and Use Tax is the greatest single source of tax receipts in the
State. For the State fiscal year ended June 30, 1997, receipts from this
source were $12,089 million, an increase of 5.5% from fiscal year 1995-96. The
second largest source of State tax receipts is the Motor Fuel Tax. The
collections from this source during the fiscal year ending June 30, 1997, were
$2,012 million. Alcoholic beverage tax revenues totalled $447.2 million for
the State fiscal year ending June 30, 1997, an increase of $5.7 million from
the previous year. The receipts of corporate income tax for the fiscal year
ended June 30, 1997 were $1,362.3 million, an increase of 17.2% from fiscal
year 1995-96. Gross Receipt tax collections for fiscal year 1996-97 totalled
$575.7 million, an increase of 6.0% over the previous fiscal year. Documentary
stamp tax collections totalled $844.2 million during fiscal year 1996-97,
posting an 8.9% increase from the previous fiscal year. The intangible
personal property tax is a tax on stocks, bonds, notes, governmental
leaseholds, certain limited partnership interests, mortgages and other
obligations secured by liens on Florida realty, and other intangible personal
property. Total collections from intangible personal property taxes were
$952.4 million during the fiscal year ending June 30, 1997, a 6.3% increase
from the previous fiscal year. Severance taxes totalled $39.2 million during
fiscal year 1995-96, up 26.1% from the previous fiscal year. In November 1986,
the voters of the State approved a constitutional amendment to allow the State
to operate a lottery. Fiscal year 1996-97 produced ticket sales of $2.09
billion of which education received approximately $792.3 million.
 
  For fiscal year 1998-99 the estimated General Revenue plus Working Capital
and Budget Stabilization funds available total $19,113.2 million, a 2.6%
increase over 1997-98. The $16,887.6 million in estimated revenues represent a
7.2% increase over the analogous figure in 1997. With combined General
Revenue, Working Capital Fund and Budget Stabilization Fund appropriations at
$17,207.0 million, unencumbered reserves at the end of 1998-99 are estimated
at $1,414.8 million.

  The State Constitution does not permit a state or local personal income tax.
An amendment to the State Constitution by the electors of the State would be
required in order to impose a personal income tax in the State.
 
  Property valuations for homestead property are subject to a growth cap.
Growth in the just (market) value of property qualifying for the homestead
exemption is limited to 3% or the change in the Consumer Price Index,
whichever is less. If the property changes ownership or homestead status, it
is to be re-valued at full just value on the next tax roll. Although the
impact of the growth cap cannot be determined, it may have the effect of
causing local government units in the State to rely more on non-ad valorem tax
revenues to meet operating expenses and other requirements normally funded
with ad valorem tax revenues.
 
  An amendment to the State Constitution was approved by statewide ballot in
the November 8, 1994 general election which is commonly referred to as the
"Limitation on State Revenues Amendment." This amendment provides that State
revenues collected for any fiscal year shall be limited to State revenues
allowed under the amendment for the prior fiscal year plus an adjustment for
growth. Growth is defined as an amount equal to the average annual rate of
growth in State personal income over the most recent twenty quarters times the
State revenues allowed under the amendment for the prior fiscal year. State
revenues collected for any fiscal year in excess of this limitation are
required to be transferred to the Budget Stabilization Fund until the fund
reaches the maximum balance specified in Section 19(g) of Article III of the
State Constitution, and thereafter is required to be refunded to taxpayers as
provided by general law. The limitation on State revenues imposed by the
amendment may be increased by the Legislature, by a two-thirds vote of each
house.
 
  The term "State revenues," as used in the amendment, means taxes, fees,
licenses, and charges for services imposed by the Legislature on individuals,
businesses, or agencies outside State government. However, the term "State
revenues" does not include: (i) revenues that are necessary to meet the
requirements set forth in documents authorizing the issuance of Bonds by the
State; (ii) revenues that are used to provide matching funds for the federal
Medicaid program with the exception of the revenues used to support the Public
Medical Assistance Trust Fund or its successor program and with the exception
of State matching funds used to fund elective expansions made after July 1,
1994; (iii) proceeds from the State lottery returned as prizes; (iv) receipts
of the Florida Hurricane Catastrophe Fund; (v) balances carried forward from
prior fiscal years; (vi) taxes, licenses, fees and charges for services
imposed by local, regional, or school district governing bodies; or (vii)
revenue from taxes, licenses, fees and charges for services required to be
imposed by any amendment or revision to the State Constitution after July 1,
1994. The amendment took effect on January 1, 1995 and is applicable to State
fiscal year 1995-96.
 
  It should be noted that many of the provisions of the amendment are
ambiguous, and likely will not be clarified until State courts have ruled on
their meanings. Further, it is unclear how the Legislature will implement the
language of the amendment and whether such implementing legislation will
itself be the subject of court interpretation.
 
  The Fund cannot predict the impact of the amendment on State finances. To
the extent local governments traditionally receive revenues from the State
which are subject to, and limited by, the amendment, the future distribution
of such State revenues may be adversely affected by the amendment.
 
  Hurricanes continue to endanger the coastal and interior portions of
Florida. Substantial damage resulted from Hurricane Andrew in 1992. During the
1995 hurricane season, a record number of tropical storms and hurricanes also
caused substantial damages. The 1996 and 1997 hurricane seasons were
uneventful with
 
                                      50
<PAGE>
 
considerably less damage than in 1992 and 1995. During the 1998 hurricane
season, which ends November 30, at least two hurricanes have caused
significant damage to several coastal communities in Florida.. The Fund cannot
predict the economic impact, if any, of future hurricanes and storms.
 
  According to the Florida General Purposes Financial Statements for fiscal
year ended June 30, 1992 as of June 30, 1997, the State had a high bond rating
from Moody's Investors Service, Inc. (Aa2), Standard & Poor's (AA+) and Fitch
IBCA, Inc. (AA) on all of its general obligation bonds. Outstanding general
obligation bonds at June 30, 1997 totalled almost $7.9 billion and were issued
to finance capital outlay for educational projects of both local school
districts, community colleges and state universities, environmental protection
and highway construction. The State has issued over $1,340 billion of general
obligation bonds since July 1, 1997.
 
  Due to investments in certain derivatives, Escambia County, Florida in 1994
sustained notable losses which may in the future affect their operations. As
reported in the local press, several lawsuits have resulted regarding such
investments.
 
  In late October, 1996, the Florida Auditor General notified the Governor's
office that seventeen municipalities or special districts are in a state of
financial emergency (including the Orlando-Orange County Expressway Authority
and the Pinellas Suncoast Transit Authority) and that another twenty-five
municipalities or special districts might be in a state of financial emergency
(including the City of Miami). For these purposes, a state of emergency is
considered two consecutive years of budget deficits. Municipalities or special
districts that may be in a state of financial emergency are those that the
Auditor General was unable to conclude had sufficient revenues to cover their
deficits. The operations of all these entities mentioned in the Auditor
General's communication may be adversely affected by their financial
condition.

                          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 edge." Interest payments are protected by a large
     or by an exceptionally stable margin and principal is secure. While
     the various protective elements are likely to change, such changes as
     can be visualized are most unlikely to impair the fundamentally strong
     position of such issues.
 
Aa   Bonds which are rated Aa are judged to be of high quality by all
     standards. Together with the Aaa group they comprise what are
     generally known as high grade bonds. They are rated lower than the
     best bonds because margins of protection may not be as large as in Aaa
     securities or fluctuation of protective elements may be of greater
     amplitude or there may be other elements present which make the long-
     term risks appear somewhat larger than in Aaa securities.
 
A    Bonds which are rated A possess many favorable investment attributes
     and are to be considered as upper medium grade obligations. Factors
     giving security to principal and interest are considered adequate, but
     elements may be present which suggest a susceptibility to impairment
     sometime in the future.
 
Baa  Bonds which are rated Baa are considered as medium grade obligations,
     i.e., they are neither highly protected nor poorly secured. Interest
     payments and principal security appear adequate for the present, but
     certain protective elements may be lacking or may be
     characteristically unreliable over any great length of time. Such
     bonds lack outstanding investment characteristics and in fact have
     speculative characteristics as well.
 
Ba   Bonds which are rated Ba are judged to have speculative elements;
     their future cannot be considered as well assured. Often the
     protection of interest and principal payments may be very moderate and
     thereby not well safeguarded during both good and bad times over the
     future. Uncertainty of position characterizes bonds in this class.
 
B    Bonds which are rated B generally lack characteristics of the
     desirable investment. Assurance of interest and principal payments or
     of maintenance of other terms of the contract over any long period of
     time may be small.
 
    
Caa  Bonds which are rated Caa are of poor standing. Such issues may be in
     default or there may be present elements of danger with respect to
     principal or interest.
    
    
Ca   Bonds which are rated Ca represent obligations which are speculative
     in a high degree. Such issues are often in default or have other
     marked shortcomings.
    
    
C    Bonds which are rated C are the lowest rated class of bonds and issues
     so rated can be regarded as having extremely poor prospects of ever
     attaining any real investment standing.
 
  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.

  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
repay punctually promissory obligations not having an original maturity in
excess of nine months. Moody's employs the following three designations, all
judged to be investment grade, to indicate the relative repayment capacity of
rated issuers:
 
  Issuers rated Prime-1 (or supporting institutions) have a superior ability
for repayment of short-term promissory 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 for
repayment of short-term promissory 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 short-term promissory obligations. The effects of
industry characteristics and market composition may be more pronounced.
Variability in earnings and profitability may result in changes to 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.
 
                                      53
<PAGE>
 
  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;
 
    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  Debt rated "AAA" has the highest rating assigned by Standard & Poor's.
     Capacity to meet its financial commitment on the obligation is
     extremely strong.
 
AA   Debt 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    Debt 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  Debt rated "BBB" exhibits adequate protection parameters. However,
     adverse economic conditions or changing circumstances are more likely
     to lead to a weakened capacity of the obligor to meet its financial
     commitment on the obligation.
 
BB   Debt rated "BB," "B," "CCC," "CC" and "C" are regarded as having
B    significant speculative characteristics. "BB" indicates the least
CCC  degree of speculation and "C" the highest degree of speculation. While
CC   such debt will likely have some quality and protective
C    characteristics, these may be outweighed by large uncertainties or
     major risk exposures to adverse conditions.
 
D    Debt rated "D" is in payment default. The "D" rating category is used
     when payments on an obligation are not made on the date due even if
     the applicable grace period has not expired, unless Standard & Poor's
     believes that such payments will be made during such grace period. The
     "D" rating also will be used upon the filing of a bankruptcy petition
     or the taking of similar action if payments on an obligation are
     jeopardized.
 
  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 or principal payments are not made on the date
     due, even if the applicable grace period has not expired unless
     Standard & Poor's believes that such payments will be made during such
     grace period.
 
  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.
 
SP-3 Speculative capacity to pay principal and interest.

DESCRIPTION OF FITCH IBCA, INC.'S ("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.
 
 
                                      55
<PAGE>
 
  Bonds carrying the same rating are of similar but not necessarily identical
credit quality since the rating categories do not fully reflect small
differences in the degrees of credit risk.
 
  Fitch ratings are not recommendations to buy, sell, or hold any security.
Ratings do not comment on the adequacy of market price, the suitability of any
security for a particular investor, or the tax-exempt nature or taxability of
payments made in respect of any security.
 
  Fitch ratings are based on information obtained from issuers, other
obligors, underwriters, their experts, and other sources Fitch believes to be
reliable. Fitch does not audit or verify the truth or accuracy of such
information. Ratings may be changed, suspended, or withdrawn as a result of
changes in, or the unavailability of, information or for other reasons.
 
AAA Bonds considered to be investment grade and of the highest credit
    quality. The obligor has an exceptionally strong ability to pay
    interest and repay principal, which is unlikely to be affected by
    reasonably foreseeable events.
 
AA  Bonds considered to be investment grade and of very high credit
    quality. The obligor's ability to pay interest and repay principal is
    very strong, although not quite as strong as bonds rated "AAA." Because
    bonds rated in the "AAA" and "AA" categories are not significantly
    vulnerable to foreseeable future developments, short-term debt of these
    issuers is generally rated "F-1+."
 
A   Bonds considered to be investment grade and of high credit quality. The
    obligor's ability to pay interest and repay principal is considered to
    be strong, but may be more vulnerable to adverse changes in economic
    conditions and circumstances than bonds with higher ratings.
 
BBB Bonds considered to be investment grade and of satisfactory-credit
    quality. The obligor's ability to pay interest and repay principal is
    considered to be adequate. Adverse changes in economic conditions and
    circumstances, however, are more likely to have adverse impact on these
    bonds, and therefore impair timely payment. The likelihood that the
    ratings of these bonds will fall below investment grade is higher than
    for bonds with higher ratings.
 
  Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus
and minus signs, however, are not used in the "AAA" category.
 
            
NR           Indicates that Fitch does not rate the specific issue.
            
            
Conditional  A conditional rating is premised on the successful completion of
             a project or the occurrence of a specific event.
            
            
Suspended    A rating is suspended when Fitch deems the amount of information
             available from the issuer to be inadequate for rating purposes.
            
            
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
D            of their ultimate recovery value in liquidation or reorganization
             of the obligor. "DDD" represents the highest potential for
             recovery on these bonds, and "D" represents the lowest potential
             for recovery.
 
 
                                      57
<PAGE>
 
  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.

                                 APPENDIX III
 
                              PORTFOLIO INSURANCE
 
  Set forth below is further information with respect to the insurance
policies (the "Policies") that the Fund may obtain from several insurance
companies with respect to insured Florida Municipal Bonds and Municipal Bonds
held by the Fund. The Fund has no obligation to obtain any such Policies, and
the terms of any Policies actually obtained may vary significantly from the
terms discussed below.
 
  In determining eligibility for insurance, insurance companies will apply
their own standards. These standards correspond generally to the standards
such companies normally use in establishing the insurability of new issues of
Florida Municipal Bonds and Municipal Bonds and are not necessarily the
criteria that would be used in regard to the purchase of such bonds by the
Fund. The Policies do not insure (i) municipal securities ineligible for
insurance and (ii) municipal securities no longer owned by the Fund.
 
  The Policies do not guarantee the market value of the insured Florida
Municipal Bonds and Municipal Bonds or the value of the shares of the Fund. In
addition, if the provider of an original issuance insurance policy is unable
to meet is obligations under such policy or if the rating assigned to the
insurance claims-paying ability of any such insurer deteriorates, the
insurance company will not have any obligation to insure any issue held by the
Fund that is adversely affected by either of the above described events. In
addition to the payment of premiums, the Policies may require that the Fund
notify the insurance company as to all Florida Municipal Bonds and Municipal
Bonds in the Fund's portfolio and permit the insurance company to audit their
records. The insurance premiums will be payable monthly by the Fund in
accordance with a premium schedule to be furnished by the insurance company at
the time the Policies are issued. Premiums are based upon the amounts covered
and the composition of the portfolio.
 
  The insurance companies used by the Fund will have insurance claims-paying
ability ratings of AAA from Standard & Poor's ("S&P") or Fitch IBCA, Inc.
("Fitch") or Aaa from Moody's Investors Service, Inc. ("Moody's").
 
  An S&P insurance claims-paying ability rating is an assessment of an
operating insurance company's financial capacity to meet obligations under an
insurance policy in accordance with the terms. An insurer with an insurance
claims-paying ability rating of AAA has the highest rating assigned by S&P or
Fitch. Capacity to honor insurance contracts is considered by S&P and Fitch to
be extremely strong and highly likely to remain so over a long period of time.
A Moody's insurance claims-paying ability rating is an opinion of the ability
of an insurance company to repay punctually senior policyholder obligations
and claims. An insurer with an insurance claims-paying ability rating of Aaa
is considered by Moody's to be of the best quality. In the opinion of Moody's,
the policy obligations of an insurance company with an insurance claims-paying
ability rating of Aaa carry the smallest degree of credit risk and, while the
financial strength of these companies is likely to change, such changes as can
be visualized are most unlikely to impair the company's fundamentally strong
position. A Fitch insurance claims-paying ability rating provides an
assessment of an insurance company's financial strength and, therefore, its
ability to pay policy and contract claims under the terms indicated. An
insurer with an insurance claims-paying ability rating of AAA has the highest
rating assigned by Fitch. The ability to pay claims is adjudged by Fitch to be
extremely strong for insurance companies with this highest rating. In the
opinion of Fitch, foreseeable business and economic risk factors should not
have any material adverse impact on the ability of these insurers to pay
claims. In Fitch's opinion, profitability, overall balance sheet strength,
capitalization and
 
                                      59
<PAGE>
 
liquidity are all at very secure levels and are unlikely to be affected by
potential adverse underwriting, investment or cyclical events.
 
  An insurance claims-paying ability rating of S&P, Fitch or Moody's does not
constitute an opinion on any specific contract in that such an opinion can
only be rendered upon the review of the specific insurance contract.
Furthermore, an insurance claims-paying ability rating does not take into
account deductibles, surrender or cancellation penalties or the timeliness of
payment; nor does it address the ability of a company to meet nonpolicy
obligations (i.e., debt contracts).
 
  The assignment of ratings by S&P, Fitch or Moody's to debt issues that are
fully or partially supported by insurance policies, contracts or guarantees is
a separate process from the determination of claims-paying ability ratings.
The likelihood of a timely flow of funds from the insurer to the trustee for
the bondholders is a key element in the rating determination for such debt
issues.

* Because Florida does not impose a personal income tax, this table reflects
  only the effect of exemption from Federal income tax. An investor's marginal
  tax rate 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 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

  or trustees of another organization in which it has any interest as a
  shareholder, creditor or otherwise) against all liabilities and expenses
  (including amounts paid in satisfaction of judgments, in compromise, as

  disregard of his duties; provided, however, that as to any matter disposed
  of by a compromise payment by such person, pursuant to a consent decree or
  otherwise, no indemnification either for said payment or for any other
  expenses shall be provided unless the Trust shall have received a written
  opinion from independent legal counsel approved by the Trustees to the
  effect that if either the matter of willful misfeasance, gross negligence
  or reckless disregard of duty, or the matter of good faith and reasonable
  belief as to the best interests of the Trust, had been adjudicated, it
  would have been adjudicated in favor of such person. The rights accruing to
  any person under these provisions shall not exclude any other right to
  which he may be lawfully entitled; provided that no person may satisfy any
  right of indemnity or reimbursement granted herein or in Section 5.1 or to
  which he may be otherwise entitled except out of the property of the Trust,
  and no Shareholder shall be personally liable to any person with respect to
  any claim for indemnity or reimbursement or otherwise. The Trustees may
  make advance payments in connection with indemnification under this Section
  5.3, provided that the indemnified person shall have given a written
  undertaking to reimburse the Trust in the event it is subsequently
  determined that he is not entitled to such indemnification."

  The Registrant's By-Laws provide that insofar as the conditional advancing
of indemnification moneys pursuant to Section 5.3 of the Declaration of Trust
for actions based upon the Investment Company Act of 1940 may be concerned,
such payments will be made only on the following conditions: (i) the advances
must be limited to amounts used, or to be used, for the preparation or
presentation of a defense to the action, including costs connected with the
preparation of a settlement; (ii) advances may be made only upon receipt of a
written promise by, or on behalf of, the recipient to repay that amount of the
advance which exceeds the amount to which it is ultimately determined he is
entitled to receive from the Registrant by reason of indemnification; and
(iii) (a) such promise must be secured by a surety bond, other suitable
insurance or an equivalent form of security which assures that any repayments
may be obtained by the Registrant without delay or litigation, which bond,
insurance or other form of security must be provided by the recipient of the
advance, or (b) a majority of a quorum of the Registrant's disinterested, non-
party Trustees, or an independent legal counsel in a written opinion, shall
determine, based upon a review of readily available facts, that the recipient
of the advance ultimately will be found entitled to indemnification.
 
  In Section 8 of the Distribution Agreement relating to the securities being
offered hereby, the Registrant agrees to indemnify the Distributor and each
person, if any, who controls the Distributor within the meaning of the
Securities Act of 1933 (the "1933 Act"), against certain types of civil
liabilities arising in connection with the Registration Statement or
Prospectus.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933, as amended (the "1933 Act") may be provided to trustees, officers and
controlling persons of the Fund, pursuant to the foregoing provisions or
otherwise, the Fund has been advised that in the opinion of the Securities and
Exchange Commission, such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Fund of expenses incurred or paid by a trustee, officer or controlling
person of the Fund in connection with any successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Fund will,
unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
 
  Reference is made to Section Six of the Purchase Agreement, a form of which
will be filed as Exhibit (h)(1) hereto, for provisions relating to the
indemnification of the underwriter.

                              DECLARATION OF TRUST

                                       OF

                      MUNIHOLDINGS FLORIDA INSURED FUND IV

     THE DECLARATION OF TRUST of MuniHoldings Florida Insured Fund IV is made
the 25th day of November, 1998, by the parties signatory hereto, as trustees
(such persons, so long as they shall continue in office in accordance with the
terms of this Declaration of Trust, and all other persons who at the time in
question have been duly elected or appointed as trustees in accordance with the
provisions of this Declaration of Trust and are then in office, being
hereinafter called the "Trustees").

                             W I T N E S S E T H :
                             - - - - - - - - - -  

     WHEREAS, the Trustees desire to form a trust fund under the law of
Massachusetts for the investment and reinvestment of funds contributed thereto;
and

     WHEREAS, it is proposed that the beneficial interest in the trust assets be
divided into transferable shares of beneficial interest as hereinafter provided;

     NOW, THEREFORE, the Trustees hereby declare that they will hold in trust
all money and property contributed to the trust fund to manage and dispose of
the same for the benefit of the holders from time to time of the shares of
beneficial interest issued hereunder and subject to the provisions hereof, to
wit:

                                   ARTICLE I.

     1.1  Name.  The name of the trust created hereby (the "Trust") shall be

MuniHoldings Florida Insured Fund IV and so far as may be practicable the
Trustees shall conduct the Trust's activities, execute all documents and sue or
be sued under that name, which name (and the word "Trust" wherever hereinafter
used) shall refer to the Trustees as Trustees, and not individually, and shall
not refer to the officers, agents, employees or Shareholders of the Trust.
However, should the Trustees determine that the use of such name is not
advisable, they may select such other name for the Trust as they deem proper and
the Trust may hold its property and conduct its activities under such other
name.  Any name change shall become effective upon the execution by a majority
of the then Trustees of an instrument setting forth the new name.  Any such
instrument shall have the status of an amendment to this Declaration.

     1.2  Definitions.  As used in this Declaration, the following terms shall
          -----------

                                   Trustees
                                   --------

     2.1  Number and Qualification.  The number of Trustees shall be fixed from
          ------------------------                                             
time to time by written instrument signed by a majority of the Trustees then in
office, provided, however, that the number of Trustees shall in no event be less
than three or more than fifteen (except prior to the first public offering of
Shares of the Trust).  Any vacancy created by an increase in Trustees may, to
the extent permitted by the 1940 Act, be filled by the appointment of an
individual having the qualifications described in this Article made by a written
instrument signed by a majority of the Trustees then in office.  Any such
appointment shall not become effective, however, until the individual named in
the written instrument of appointment shall have accepted in writing such
appointment and agreed in writing to be bound by the terms of this Declaration.
No reduction in the number of Trustees shall have the effect of removing any
Trustee from office prior to the expiration of this term.  Whenever a vacancy in
the number of Trustees shall occur, until such vacancy is filled as provided in
Section 2.3 hereof, the Trustees in office, regardless of their number, shall
have all the powers granted to the Trustees and shall discharge all the duties
imposed upon the Trustees by this Declaration.  A Trustee shall be an individual
at least 21 years of age who is not under legal disability.  Trustees need not

     2.2  Term of Office of Trustees.  The term of office of all of the Trustees
          --------------------------                                            
named herein, or elected or appointed prior to the first annual meeting of
Shareholders, shall expire on the date of the first annual meeting of
Shareholders or special meeting in lieu thereof.  Beginning with the Trustees
elected at the first annual meeting of Shareholders, the term of each Trustee
shall expire at the next annual meeting of Shareholders following the election
or appointment of such Trustee and upon the election and qualification of his
successor.  The Trustees shall be elected by the affirmative vote of the holders
of a majority of the Shares present in person or by proxy at an annual meeting
of Shareholders or special meeting in lieu thereof called for that purpose,
except as provided in Section 2.3 of this Article; provided, however, that the
                                                   --------  -------          
Preferred Shareholders voting as a class at an annual meeting of the
Shareholders or special meeting in lieu thereof called for such purpose, shall
elect at least two (2) Trustees at all times, and, provided, further, that the
                                                   --------  -------          
Preferred Shareholders voting as a class shall elect at least a majority of the
Trustees, which number of Trustees shall be increased appropriately in order to
effectuate such rights after giving effect to resignations of Trustees, (i) if
at any time the dividends on the Preferred Shares shall be unpaid in an amount
equal to two (2) full years' dividends on the

                                       3
<PAGE>
 
Preferred Shares, with such representation to continue until all dividends in
arrears shall have been paid or otherwise provided for, or (ii) pursuant to the
designations and powers, preferences and rights and the qualifications,
limitations and restrictions of the Preferred Shares as determined in accordance
with Section 6.1 hereof. Each Trustee elected shall hold office until his
successor shall have been elected and shall have qualified or until such time as
may otherwise be provided in the By-Laws adopted or amended pursuant to Section
2.7 hereof; except that (a) any Trustee may resign his trust (without need for
prior or subsequent accounting) by an instrument in writing signed by him or her
and delivered to the other Trustees, which shall take effect upon such delivery
or upon such later date as is specified therein; (b) any Trustee may be removed
(provided the aggregate number of Trustees after such removal shall not be less
than the number required by Section 2.1 hereof) with cause, at any time by
written instrument, signed by the remaining Trustees, specifying the date when
such removal shall become effective, provided, however, that the Trustees
                                     --------  ------- 
elected by one class of Shares shall have no power to so remove
any Trustee elected by another class of Shares; (c) any Trustee who requests in
writing to be retired or who has become incapacitated by illness or injury may
be retired by written instrument signed by a majority of the other Trustees,
specifying the date of his retirement; and (d) a Trustee may be removed at any
meeting of Shareholders by a vote of two thirds of the outstanding Shares of the
class or classes of Shares of beneficial interest that elected such Trustee.
Upon the resignation or removal of a Trustee, or his otherwise ceasing to be
Trustee, he shall execute and deliver such documents as the remaining Trustees
shall require for the purpose of conveying to the Trust or the remaining
Trustees any Trust property held in the name of the resigning or removed
Trustee. Upon the incapacity or death of any Trustee, his legal representative
shall execute and deliver on his behalf such documents as the remaining Trustees
shall require as provided in the preceding sentence.

     2.3  Resignation and Appointment of Trustees.  In case of the declination,
          ---------------------------------------                              
death, resignation, retirement, removal or inability of any of the Trustees, or
in case a vacancy shall, by reason of an increase in number, or for any other
reason, exist, the remaining Trustees or, prior to the public offering of Shares
of the Trust, if only one Trustee shall then remain in office, the remaining
Trustee, shall fill such vacancy by appointing such other person as they or he,
in their or his discretion, shall see fit.  Such appointment shall be evidenced
by a written instrument signed by a majority of the remaining Trustees or by the
remaining Trustee, as the case may be.  Any such appointment shall not become
effective, however, until the person named in the written instrument or
appointment shall have accepted in writing such appointment and agreed in
writing to be bound by the terms of the Declaration.  Within twelve months of
such appointment, the Trustees shall cause notice of such appointment to be
mailed to each Shareholder at his address as recorded on the books of the Trust.
An appointment of a Trustee may be made by the Trustees then in office and
notice thereof mailed to Shareholders aforesaid in anticipation of a vacancy to
occur by reason of retirement, resignation or increase in number of Trustees
effective at a later date, provided that said appointment shall become effective
only at or after the effective date of said retirement, resignation or increase
in number of Trustees.  The power of appointment is subject to the provisions of
section 16(a) of the 1940 Act.

     2.4  Vacancies.  The death, declination, resignation, retirement, removal
          ---------                                                           
or incapacity of the Trustees, or any one of them, shall not operate to annul
the Trust or to revoke any existing agency created pursuant to the terms of this
Declaration.  Whenever a vacancy in the number of Trustees shall occur, until
such vacancy is filled as provided in Section 2.3, the Trustees in

                                       4
<PAGE>
 
office, regardless of their number, shall have all the powers granted to the
Trustees and shall discharge all the duties imposed upon the Trustees by the
Declaration subject to the rights of the holders of the Preferred Shares to
elect a Trustee to fill such vacancy in accordance with the terms and provisions
hereof. A written instrument certifying the existence of such vacancy signed by
a majority of the Trustees shall be conclusive evidence of the existence of such
vacancy.

     2.5  Meetings.  Meetings of the Trustees shall be held from time to time
          --------                                                           
upon the call of the Chairman, if any, the President, the Secretary or any two
Trustees.  Regular meetings of the Trustees may be held without call or notice
at a time and place fixed by the By-Laws or by resolution of the Trustees.
Notice of any other meeting shall be mailed or otherwise given not less than 48
hours before the meeting but may be waived in writing by any Trustee either
before or after such meeting.  The attendance of a Trustee at a meeting shall
constitute a waiver of notice of such meeting except where a Trustee attends a
meeting for the express purpose of objecting to the transaction of any business
on the ground that the meeting has not been lawfully called or convened.  The
Trustees may act with or without a meeting.  A quorum for all meetings of the
Trustees shall be a majority of the Trustees.  Unless provided otherwise in this
Declaration, any action of the Trustees may be taken at a meeting by vote of a
majority of the Trustees present (a quorum being present) or without a meeting
by written consents of a majority of the Trustees.

     Any committee of the Trustees, including an executive committee, if any,
may act with or without a meeting.  A quorum for all meetings of any such
committee shall be a majority of the members thereof.  Unless provided otherwise
in this Declaration, any action of any such committee may be taken at a meeting
by vote of a majority of the members present (a quorum being present) or without
a meeting by written consent of a majority of the members.

     With respect to actions of the Trustees and any committee of the Trustees,
Trustees who are Interested Persons of the Trust within the meaning of Section
1.2 hereof or otherwise interested in any action to be taken may be counted for
quorum purposes under this Section and shall be entitled to vote to the extent
permitted by the 1940 Act.

     All or any one or more Trustees may participate in a meeting of the
Trustees or any committee thereof by means of a conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other and participation in a meeting pursuant to such
communication systems shall constitute presence in person at such meeting.

     2.6  Officers.  The Trustees shall annually elect a President, a Secretary
          --------                                                             
and a Treasurer and may elect a Chairman.  The Trustees may elect or appoint or
authorize the Chairman, if any, or President to appoint such other officers or
agents with such powers as the Trustees may deem to be advisable.  The Chairman
and President shall be and the Secretary and Treasurer may, but need not, be a
Trustee.

     2.7  By-Laws.  The Trustees may adopt and from time to time amend or repeal
          -------                                                               
the By-Laws for the conduct of the business of the Trust.

the Trust Property and over the business of the Trust to the same extent as if
the Trustees were the sole owners of the Trust Property and business in their
own right, but with such powers of delegation as may be permitted by this
Declaration.  The Trustees may perform such acts as in their sole discretion are
proper for conducting the business of the Trust.  The enumeration of any
specific power herein shall not be construed as limiting the aforesaid power.
Such powers of the Trustees may be exercised without order of or resort to any
court.

     3.2  Investments.  The Trustees shall have power, subject to the

     company;

     instrumentalities, or by the United States Government or its agencies or
     instrumentalities, or international instrumentalities, or by any bank,
     savings institution, corporation or other business entity organized under
     the laws of the United States and, to the extent provided in the Prospectus
     and Registration Statement and not prohibited by the Fundamental Policies,
     organized under foreign laws; and to exercise any and all rights, powers
     and privileges of ownership or interest in respect of any and all such
     investments of every kind and description, including, without limitation,
     the right to consent and otherwise act with respect thereto, with power to
     designate one or more persons, firms, associations or corporations to
     exercise any of said rights, powers and privileges in respect of any of
     said instruments; and the Trustees shall be deemed to have the foregoing
     powers with respect to any additional securities in which the Trust may
     invest should the investment policies set forth in the Prospectus and
     Registration Statement or the Fundamental Policies be amended.

     The Trustees shall not be limited to investing in obligations maturing
before the possible termination of the Trust, nor shall the Trustees be limited
by any law limiting the investments which may be made by fiduciaries.

     3.3  Legal Title.  Legal title to all the Trust Property shall be vested in
          -----------

legal title to any Trust Property to be held by or in the name of one or more of
the Trustees, or in the name of the Trust, or in the name of any other Person as
nominee, on such terms as the Trustees may determine, provided that the interest
of the Trust therein is appropriately protected.

                                       6
<PAGE>
 
     The right, title and interest of the Trustees in the Trust Property shall
vest automatically in each person who may hereafter become a Trustee upon his
due election and qualification.  Upon the resignation, removal or death of a
Trustee he shall automatically cease to have any right, title or interest in any
of the Trust Property, and the right, title and interest of such Trustee in the
Trust Property shall vest automatically in the remaining Trustees.  Such vesting
and cessation of title shall be effective whether or not conveyancing documents
have been executed and delivered.

     3.4  Issuance and Repurchase of Securities.  The Trustees shall have the
          -------------------------------------

reissue, dispose of, transfer, and otherwise deal in, Shares, including shares
in fractional denominations, and, subject to the more detailed provisions set

have power to borrow money or otherwise obtain credit and to secure the same by
mortgaging, pledging or otherwise subjecting as security the assets of the

other person, firm, association or corporation.

          ----------------------                                            
with their continuing exclusive authority over the management of the Trust and
the Trust Property, to delegate from time to time to such of their number or to
officers, employees or agents of the Trust the doing of such things and the
execution of such instruments either in the name of the Trust or the names of
the Trustees or otherwise as the Trustees may deem expedient, to the same extent
as such delegation is permitted to directors of a Massachusetts business
corporation and as permitted by the 1940 Act.

     3.7  Collection and Payment.  The Trustees shall have power to collect all
          ----------------------                                               
property due to the Trust; to pay all claims including taxes, against the Trust

          --------                                                              
which in the opinion of the Trustees are necessary or incidental to carry out
any of the purposes of this Declaration, and to pay reasonable compensation from
the funds of the Trust to themselves as Trustees. The Trustees shall fix the
compensation of all officers, employees and Trustees. The Trustees may pay
themselves such compensation for special services, including legal,
underwriting, syndicating and brokerage services, as they in good faith may deem
reasonable and reimbursement for expenses reasonably incurred by themselves on
behalf of the Trust.

     3.9  Miscellaneous Powers.  The Trustees shall have the power to: (a)
          --------------------

extent as the Trustees shall determine; (g) guarantee indebtedness or
contractual obligations of others; (h) determine and change the fiscal year of
the Trust and the method by which its accounts shall be kept; and (i) adopt a
seal for the Trust, but the absence of such seal shall not impair the validity
of any instrument executed on behalf of the Trust.

     3.10  Further Powers.  The Trustees shall have power to conduct the
           --------------                                               
business of the Trust and carry on its operations in any and all of its branches
and maintain offices both within and without the Commonwealth of Massachusetts,
in any and all states of the United States of America, in the District of
Columbia, and in any and all commonwealths, territories, dependencies, colonies,
possessions, agencies or instrumentalities of the United States of America and
of foreign governments, and to do all such other things and execute all such
instruments as they deem necessary, proper or desirable in order to promote the
interests of the Trust although such things are not herein specifically
mentioned.  Any determination as to what is in the interests of the Trust made
by the Trustees in good faith shall be conclusive.  In construing the provisions
of this Declaration, the presumption shall be in favor of a grant of power to
the Trustees.  The Trustees will not be required to obtain any court order to
deal with the Trust Property.


                                  ARTICLE IV.

                   Management and Distribution Arrangements
                   ----------------------------------------

     4.1  Management Arrangements.  Subject to a Majority Shareholder Vote, as
          -----------------------                                             
required by the 1940 Act, the Trustees may in their discretion from time to time
enter into advisory or management contracts whereby the other party to such
contract shall undertake to furnish the Trustees such advisory and management
services as the Trustees shall from time to time consider desirable and all upon
such terms and conditions as the Trustees may in their discretion determine.
Notwithstanding any provisions of this Declaration, the Trustees may authorize
any adviser or manager (subject to such general or specific instructions as the
Trustees may from time to time adopt) to effect purchases, sales, loans or
exchanges of portfolio securities of the Trust on behalf of the Trustees or may
authorize any officer, employee or Trustee to effect such purchases, sales,
loans or exchanges pursuant to recommendations of any such adviser or manager
(and all without further action by the Trustees). Any such purchases, sales,
loans and exchanges shall be deemed to have been authorized by all of the
Trustees.

     4.2  Distribution Arrangements.  The Trustees may in their discretion from
          -------------------------                                            
time to time enter into a contract, providing for the sale of the Shares of the
Trust to net the Trust not less than the par value per share, whereby the Trust
may either agree to sell the Shares to the other party to the contract or
appoint such other party its sales agent for such Shares.  In either case, the
contract shall be on such terms and conditions as the Trustees may in their
discretion determine not inconsistent with the provisions of this Article IV or
the By-Laws; and such contract may also provide for the repurchase or sale of
Shares by such other party as principal or as agent of the Trust and may provide
that such other party may enter into selected dealer agreements with registered
securities dealers to further the purpose of the distribution or repurchase of
the Shares.

     4.3  Parties to Contract.  Any contract of the character described in
          -------------------                                             
Section 4.1 and 4.2 of this Article IV or in Article VII hereof may be entered
into with any corporation, firm, trust or association, although one or more of
the Trustees or officers of the Trust may be an officer, director, Trustee,
shareholder, or member of such other party to the contract, and no such contract
shall be invalidated or rendered voidable by reason of the existence of any such
relationship, nor shall any person holding such relationship be liable merely by
reason of such relationship for any loss or expense to the Trust under or by
reason of said contract or accountable for any profit realized directly or
indirectly therefrom, provided that the contract when entered into was
reasonable and fair and not inconsistent with the provisions of this Article IV
or the By-Laws.  The same person (including a firm, corporation, trust, or
association) may be the other party to contracts entered into pursuant to
Sections 4.1 and 4.2 above or Article VII, and any individual may be financially
interested or otherwise affiliated with persons who are parties to any or all of
the contracts mentioned in this Section 4.3.

     4.4  Provisions and Amendments.  Any contract entered into pursuant to
          -------------------------                                        
Section 4.1 and 4.2 of this Article IV shall be consistent with and subject to
the requirements of Section 15 of the 1940 Act with respect to its continuance
in effect, its termination, and the method of authorization and approval of such
contract or renewal thereof, and no amendment to any contract, entered into
pursuant to Section 4.1 shall be effective unless assented to by a Majority
Shareholder Vote.


                                  ARTICLE V.

         Limitations of Liability of Shareholders Trustees and Others
         ------------------------------------------------------------

     5.1  No Personal Liability of Shareholders,  Trustees, etc.  No Shareholder
          ------------------------------------------------------                
shall be subject to any personal liability whatsoever to any Person in
connection with Trust Property or the acts, obligations or affairs of the Trust.
No Trustee, officer, employee or agent of the Trust shall be subject to any
personal liability whatsoever to any Person, other than the Trust or its
Shareholders, in connection with Trust Property or the affairs of the Trust,
save only that arising from his bad faith, willful misfeasance, gross negligence
or reckless disregard of his duty to such Person; and all such Persons shall
look solely to the Trust Property for satisfaction of claims of any nature
arising in connection with the affairs of the Trust. If any Shareholder,
Trustee, officer, employee, or agent, as such, of the Trust, is made a party to
any suit or proceeding to enforce any such liability, he shall not on account
thereof, be held to any personal liability. The Trust shall indemnify and hold
each Shareholder harmless from and against all claims and

                                       9
<PAGE>
 
liabilities, to which such Shareholder may become subject by reason of his being
or having been a Shareholder, and shall reimburse such Shareholder for all legal
and other expenses reasonably incurred by him in connection with any such claim
or liability. The rights accruing to a Shareholder under this Section 5.1 shall
not exclude any other right to which such Shareholder may be lawfully entitled,
nor shall anything herein contained restrict the right of the Trust to indemnify
or reimburse a Shareholder in any appropriate situation even though not
specifically provided herein.

     5.2  Non-Liability of Trustees, etc.  No Trustee, officer employee or agent
          -------------------------------                                       
of the Trust shall be liable to the Trust, its Shareholders, or to any
shareholder, Trustee, officer, employee, or agent thereof for any action or
failure to act (including without limitation the failure to compel in any way
any former or acting Trustee to redress any breach of trust) except for his own
bad faith, willful misfeasance, gross negligence or reckless disregard of his
duties.

     5.3  Mandatory Indemnification.  The Trust shall indemnify each of its
          -------------------------                                        
Trustees, officers, employees, and agents (including persons who serve at its
requests as directors, officers or trustees of another organization in which it
has any interest, as a shareholder, creditor or otherwise) against all
liabilities and expenses (including amounts paid in satisfaction of judgments,
in compromise, as fines and penalties, and as counsel fees) reasonably incurred
by him in connection with the defense or disposition of any action, suit or
other proceeding, whether civil or criminal, in which he may be involved or with
which he may be threatened, while in office or thereafter, by reason of his
being or having been such a Trustee, officer, employee or agent, except with
respect to any matter as to which he shall have been adjudicated to have acted
in bad faith, willful misfeasance, gross negligence or reckless disregard of his
duties; provided, however, that as to any matter disposed of by a compromise
payment by such person, pursuant to a consent decree or otherwise, no
indemnification either for said payment or for any other expenses shall be
provided unless the Trust shall have received a written opinion from independent
legal counsel approved by the Trustees to the effect that if either the matter
of willful misfeasance, gross negligence or reckless disregard of duty, or the
matter of good faith and reasonable belief as to the best interests of the
Trust, had been adjudicated, it would have been adjudicated in favor of such
person.  The rights accruing to any Person under these provisions shall not
exclude any other right to which he may be lawfully entitled; provided that no
Person may satisfy any right of indemnity or reimbursement granted herein or in
Section 5.l or to which he may be otherwise entitled except out of the property
of the Trust, and no Shareholder shall be personally liable to any Person with
respect to any claim for indemnity or reimbursement or otherwise.  The Trustees
may make advance payments in connection with indemnification under this Section
5.3, provided that the indemnified person shall have given a written undertaking
to reimburse the Trust in the event it is subsequently determined that he is not
entitled to such indemnification.

     5.4  No Bond Required of Trustees.  No Trustee shall, as such, be obligated
          ----------------------------                                          
to give any bond or surety or other security for the performance of any of his
duties hereunder.

     5.5  No Duty of Investigation; Notice in Trust Instruments, etc.  No
          ----------------------------------------------------------     
purchaser, lender, transfer agent or other person dealing with the Trustees or
any officer, employee or agent of the Trust shall be bound to make any inquiry
concerning the validity of any transaction purporting to be made by the Trustees
or by said officer, employee or agent or be liable for the application of

                                       10
<PAGE>
 
money or property paid, loaned, or delivered to or on the order of the Trustees
or of said officer, employee or agent. Every obligation, contract, instrument,
certificate, Share, other security of the Trust or undertaking, and every other
act or thing whatsoever executed in connection with the Trust shall be
conclusively taken to have been executed or done by the executors thereof only
in their capacity as Trustees under this Declaration or in their capacity as
officers, employees or agents of the Trust. Every written obligation, contract,
instrument, certificate, Share, other security of the Trust or undertaking made
or issued by the Trustees or by any officers, employees or agents of the Trust,
in their capacity as such, shall contain an appropriate recital to the effect
that the Shareholders, Trustees, officers, employees and agents of the Trust
shall not personally be bound by or liable thereunder, nor shall resort be had
to their private property for the satisfaction of any obligation or claim
thereunder and appropriate references shall be made therein to the Declaration,
and may contain any further recital which they may deem appropriate, but the
omission of such recital shall not operate to impose personal liability on any
of the Trustees, Shareholders, officers, employees or agents of the Trust. The
Trustees may maintain insurance for the protection of the Trust Property, its
Shareholders, Trustees, officers, employees and agents in such amount as the
Trustees shall deem adequate to cover possible tort liability, and such other
insurance as the Trustees in their sole judgment shall deem advisable.

     5.6  Reliance on Experts, etc.  Each Trustee and officer or employee of the
          -------------------------                              
Trust shall, in the performance of his duties, be fully and completely justified
and protected with regard to any act or any failure to act resulting from
reliance in good faith upon the books of account or other records of the Trust,
upon an opinion of counsel, or upon reports made to the Trust by any of its
officers or employees or by any investment adviser, distributor, selected
dealers, accountants, appraisers or other experts or consultants elected with
reasonable care by the Trustees, officers or employees of the Trust, regardless
of whether such counsel or expert may also be a Trustee.



                                  ARTICLE VI.

                         Shares of Beneficial Interest
                         -----------------------------

     6.1.  Beneficial Interest.  The interest of the beneficiaries hereunder
           -------------------                                              
shall be divided into transferable shares of beneficial interest of $0.10 par
value.  The Trustees of the Trust may authorize separate classes of shares
together with such designations and powers, preferences and rights,
qualifications, limitations and restrictions as may be determined from time to
time by the Trustees.  The number of such shares of beneficial interest
authorized hereunder is unlimited.  All Shares issued hereunder including,
without limitation, Shares issued in connection with a dividend in Shares or a
split in shares, shall be fully paid and nonassessable.

     Pursuant to the powers vested in the Trustees by this Section 6.1, the
Trustees hereby authorize the issuance of an unlimited number of common shares
of beneficial interest, par value $0.10 per share (the "Common Shares"),
together with [1,000,000] preferred shares of beneficial interest, par value of
$0.10 per share (the "Preferred Shares").

     The designations and powers, preferences and rights, and the
qualifications, limitations and restrictions of the Common Shares are as set
forth in this Declaration of Trust.

                                       11
<PAGE>
 
     The designations and powers, preferences and rights, and the
qualifications, limitations and restrictions of the Preferred Shares are as
follows:

     The Preferred Shares shall be issued from time to time in one or more
series with such distinctive serial designations and (i) may have such voting
powers, full or limited; (ii) may be subject to redemption at such time or times
and at such price or prices; (iii) may be entitled to receive dividends (which
may be cumulative or noncumulative) at such rate or rates, on such conditions,
and at such times, and payable in preference to, or in such relation to, the
dividends payable on any other class or classes of shares; (iv) may have such
preferences or other rights upon the dissolution of, or upon any distribution of
the assets of, the Trust; (v) may be made convertible into, or exchangeable for,
shares of any other class or classes of shares of the Trust, at such price or
prices or at such rates of exchange and with such adjustments; (vi) shall have
such other relative, participating, optional or other special rights,
qualifications, limitations or restrictions thereof, all as shall hereafter be
stated and expressed in the resolution or resolutions providing for the issue of
such Preferred Shares from time to time adopted by the Trustees pursuant to
authority so to do which is hereby expressly vested in the Board; and are as
further set out in this Declaration of Trust.  A certificate signed by the
Secretary or an Assistant Secretary of the Trust setting forth the resolution or
resolutions providing for such issuance of Preferred Shares and reciting that
such resolution was or such resolutions were duly adopted by the Trustees (the
"Certificate of Designation") shall be conclusive evidence of the action
providing for the issuance of such Preferred Shares when lodged among the
records of the Trust.

     6.2.  Rights of Shareholders.  The ownership of the Trust Property of every
           ----------------------                                               
description and the right to conduct any business hereinbefore described are
vested exclusively in the Trustees, and the Shareholders shall have no interest
therein other than the beneficial interest conferred by their Shares, and they
shall have no right to call for any partition or division of any property,
profits, rights or interests of the Trust nor can they be called upon to share
or assume any losses of the Trust or suffer an assessment of any kind by virtue
of their ownership of Shares.  The Shares shall be personal property giving only
the rights in this Declaration specifically set forth.  The Shares shall not
entitle the holder to preference, preemptive, appraisal, conversion or exchange
rights, except for rights of appraisal specified in Section 10.4 and except as
the Trustees may determine with respect to any class or series of Shares.

     6.3.  Trust Only.  It is the intention of the Trustees to create only the
           ----------                                                         
relationship of Trustee and beneficiary between the Trustees and each
Shareholder from time to time.  It is not the intention of the Trustees to
create a general partnership, limited partnership, joint stock association,
corporation, bailment or any form of legal relationship other than a trust.
Nothing in this Declaration shall be construed to make the Shareholders, either
by themselves or with the Trustees, partners or members of a joint stock
association.

     6.4.  Issuance of Shares.  The Trustees, in their discretion, may from time
           ------------------                                                   
to time without a vote of the Shareholders issue Shares, in addition to the then
issued and outstanding Shares and Shares held in the treasury, to such party or
parties and for such amount not less than par value and type of consideration,
including cash or property, at such time or times, and on such terms as the
Trustees may deem best, and may in such manner acquire other assets (including
the acquisition of assets subject to, and in connection with the assumption of,
liabilities) and businesses.  In connection with any issuance of Shares, the
Trustees may issue 

                                       12
<PAGE>
 
fractional Shares. The Trustees may from time to time divide or combine the
Shares into a greater or lesser number without thereby changing the
proportionate beneficial interests in the Trust. Contributions to the Trust may
be accepted for, and Shares shall be redeemed as, whole Shares and/or 1/1,000ths
of a Share or multiples thereof.

     6.5.  Register of Shares.  A register shall be kept at the Trust or a
           ------------------                                             
transfer agent duly appointed by the Trustees under the direction of the
Trustees which shall contain the names and addresses of the Shareholders and the
number of Shares held by them respectively and a record of all transfers
thereof.  Such register shall be conclusive as to who are the holders of the
Shares and who shall be entitled to receive dividends or distributions or
otherwise to exercise or enjoy the rights of Shareholders.  No Shareholder shall
be entitled to receive payment of any dividend or distribution, nor to have
notice given to him as herein provided, until he has given his address to a
transfer agent or such other officer or agent of the Trustees as shall keep the
said register for entry thereon.  It is not contemplated that certificates will
be issued for the Shares; however, the Trustees, in their discretion, may
authorize the issuance of share certificates and promulgate appropriate rules
and regulations as to their use.

     6.6.  Transfer Agent and Registrar.  The Trustee shall have power to employ
           ----------------------------                                         
a transfer agent or transfer agents, and a registrar or registrars.  The
transfer agent or transfer agents may keep the said register and record therein
the original issues and transfers, if any, of the said Shares.  Any such
transfer agent and registrar shall perform the duties usually performed by
transfer agents and registrars of certificates of stock in a corporation, except
as modified by the Trustees.

     6.7.  Transfer of Shares.  Shares shall be transferable on the records of
           ------------------                                                 
the Trust only by the record holder thereof or by his agent thereto duly
authorized in writing, upon delivery to the Trustees or a transfer agent of the
Trust of a duly executed instrument of transfer, together with such evidence of
the genuineness of each such execution and authorization and of other matters as
may reasonably be required.  Upon such delivery the transfer shall be recorded
on the register of the Trust.  Until such record is made, the Shareholder of
record shall be deemed to be the holder of such Shares for all purposes hereof
and neither the Trustees nor any transfer agent or registrar nor any officer,
employee or agent of the Trust shall be affected by any notice of the proposed
transfer.

          Any person becoming entitled to any Shares in consequence of the
death, bankruptcy, or incompetence of any Shareholder, or otherwise by operation
of law, shall be recorded on the register of Shares as the holder of such Shares
upon production of the proper evidence thereof to the Trustees or a transfer
agent of the Trust, but until such record is made, the Shareholder of record
shall be deemed to be the holder of such Shares for all purposes hereof and
neither the Trustees nor any transfer agent or registrar nor any officer or
agent of the Trust shall be affected by any notice of such death, bankruptcy or
incompetence, or other operation of law.

     6.8.  Notices.  Any and all notices to which any Shareholder hereunder may
           -------                                                             
be entitled and any and all communications shall be deemed duly served or given
if mailed, postage prepaid, addressed to any Shareholder of record at his last
known address as recorded on the register of the Trust.

                                   Custodian
                                   ---------

     7.1.  Appointment and Duties.  The Trustees shall at all times employ
           ----------------------                                         
custodian or custodians, meeting the qualifications for custodians for portfolio
securities of investment companies contained in the 1940 Act, as custodian with
authority as its agent, but subject to such restrictions, limitations and other
requirements, if any, as may be contained in the By-Laws of the Trust and the
1940 Act:

           (1)  to hold the securities owned by the Trust and  deliver the same
     upon written order;

           (2) to receive and receipt for any moneys due to the Trust and
     deposit the same in its own banking department or elsewhere as the Trustees
     may direct;

           (3) to disburse such funds upon orders or vouchers;

           (4) if authorized by the Trustees, to keep the books and accounts of
     the Trust and furnish clerical and accounting services; and

           (5) if authorized to do so by the Trustees, to compute the net income
     of the Trust;

all upon such basis of compensation as may be agreed upon between the Trustees
and the custodian.  If so directed by a Majority Shareholder Vote, the custodian
shall deliver and pay over all property of the Trust held by it as specified in
such vote.

     The Trustees may also authorize the custodian to employ one or more sub-
custodians from time to time to perform such of the acts and services of the
custodian and upon such terms and conditions, as may be agreed upon between the
custodian and such sub-custodian and approved by the Trustees, provided that in
every case such sub-custodian shall meet the qualifications for custodians
contained in the 1940 Act.

     7.2.  Central Certificate System.  Subject to such rules, regulations and
           --------------------------                                         
orders as the Commission may adopt, the Trustees may direct the custodian to
deposit all or any part of the securities owned by the Trust in a system for the
central handling of securities established by a national securities exchange or
a national securities association registered with the Commission under the
Securities Exchange Act of 1934, or such other person as may be permitted by the
Commission, or otherwise in accordance with the 1940 Act, pursuant to which
system all securities of any particular class or series of any issuer deposited
within the system are treated as fungible and may be transferred or pledged by
bookkeeping entry without physical delivery of such securities, provided that
all such deposits shall be subject to withdrawal only upon the order of the
Trust.

                                 ARTICLE VIII.

        Determination of Net Asset Value, Net Income and Distributions
        --------------------------------------------------------------

     8.1.  Net Asset Value.  The net asset value of each outstanding Share of
           ---------------                                                   
the Trust shall be determined at such time or times on such days as the Trustees
may determine, in accordance with the 1940 Act.  The method of determination of
net asset value of Shares of each class shall be determined by the Trustees and
shall be as set forth in the Prospectus and Registration Statement with any
expenses being borne solely by a class of Shares being reflected in the net
asset value of such Shares.  The power and duty to make the daily calculations
may be delegated by the Trustees to the adviser, administrator, manager,
custodian, transfer agent or such other person as the Trustees may determine.
The Trustees may suspend the daily determination of net asset value to the
extent permitted by the 1940 Act.

     8.2.  Distributions to Shareholders.  The Trustees shall from time to time
           -----------------------------                                       
distribute ratably among the Shareholders such proportion of the net profits,
surplus (including paid-in surplus), capital, or assets held by the Trustees as
they deem proper with any expenses being borne solely by a class of Shares being
reflected in the net profits or other assets being distributed to such class.
Such distribution may be made in cash or property (including without limitation
any type of obligations of the Trust or any assets thereof), and the Trustees
may distribute ratably among the Shareholders additional Shares issuable
hereunder in such manner, at such times, and on such terms as the Trustees may
deem proper.  Such distributions may be among the Shareholders of record at the
time of declaring a distribution or among the Shareholders of record at such
later date as the Trustees shall determine.  The Trustees may always retain from
the net profits such amounts as they may deem necessary to pay the debts or
expenses of the Trust or to meet obligations of the Trust, or as they deem
desirable to use in the conduct of its affairs or to retain for future
requirements or extensions of the business.  The Trustees may adopt and offer to
Shareholders such dividend reinvestment plans, cash dividend payout plans or
related plans as the Trustees shall deem appropriate.

     Inasmuch as the computation of net income and gains for federal income tax
purposes may vary from the computation thereof on the books, the above
provisions shall be interpreted to give the Trustees the power in their
discretion to distribute for any fiscal year as ordinary dividends and as
capital gains distributions, respectively, additional amounts sufficient to
enable the Trust to avoid or reduce liability for taxes.

     8.3.  Power to Modify Foregoing Procedures.  Notwithstanding any of the
           ------------------------------------                             
foregoing provisions of this Article VIII, the Trustees may prescribe, in their
absolute discretion, such other bases and times for determining the per share
net asset value of the Trust's Shares or net income, or the declaration and
payment of dividends and distributions as they deem necessary or desirable or to
enable the Trust to comply with any provision of the 1940 Act, including any
rule or regulation adopted pursuant to the 1940 Act by the Commission or any
securities association registered under the Securities Exchange Act of 1934, all
as in effect now or hereafter amended or modified.

     9.1.  Voting Powers.  The Shareholders shall have power to vote only (i)
           -------------

of the Trust or the Shareholders, (x) with respect to such additional matters
relating to the Trust as may be required by law, the Declaration, the By-Laws or
any registration of the Trust with the Commission (or any successor agency) or
any state, or as and when the Trustees may consider necessary or desirable, and
(xi) with respect to those matters set forth in the designations and powers,
preferences and rights and the qualifications, limitations and restrictions of
the Preferred Shares, as determined in accordance with Section 6.1 hereof.  Each
whole Share shall be entitled to one vote as to any matter on which it is
entitled to vote and each fractional Share shall be entitled to a proportionate
fractional vote, except that Shares held in the treasury of the Trust as of the
record date, as determined in accordance with the By-Laws, shall not be voted.
There shall be no cumulative voting in the election of Trustees.  Until Shares
are issued, the Trustees may exercise all rights of Shareholders and may take
any action required by law, the Declaration or the By-Laws to be taken by
Shareholders.  The By-Laws may include further provisions for Shareholders'
votes and meetings and related matters.

     9.2.  Meetings of Shareholders.
           ------------------------ 

           (a) Annual Meetings.  Annual meetings of the Shareholders shall be
              ----------------                       
held at such place within or without the Commonwealth of Massachusetts on such
day and at such time as the Trustees shall designate.

           (b) Special Meetings.  Special meetings of the Shareholders may be
              -----------------
called at any time by a majority of the Trustees and shall be called by any
Trustee upon written request of Shareholders holding in the aggregate not less
than 10% of the outstanding Shares having voting rights, such request specifying
the purpose or purposes for which such meeting is to be called.  Any such
meeting shall be held within or without the Commonwealth of Massachusetts on
such day and at such time as the Trustees shall designate.

     The holders of a majority of the outstanding Shares present in person or by
proxy shall constitute a quorum at any annual or special meeting for the
transaction of any business, except as may otherwise be required by the 1940
Act, the laws of the Commonwealth of Massachusetts or other applicable law or by
this Declaration or the By-Laws of the Trust.  If a quorum is present at a
meeting, the affirmative vote of a majority of the Shares represented at the
meeting 

                                       16
<PAGE>
 
constitutes the action of the Shareholders, unless the 1940 Act, the laws of the
Commonwealth of Massachusetts or other applicable law, the Declaration or the
By-Laws of the Trust requires a greater number of affirmative votes. If the
Shares shall be divided into classes with a class having exclusive voting rights
with respect to certain matters, the aforesaid quorum and voting requirements
with respect to action to be taken by the Shareholders of the class on such
matters shall be applicable only to the Shares of such class.

     9.3.  Notice of Meetings.  Notice of all meetings of the Shareholders,
           ------------------                                              
stating the time, place and purposes of the meeting, shall be given by the
Trustees by mail to each Shareholder at his registered address, mailed at least
10 days and not more than 60 days before the meeting.  Only the business stated
in the notice of the meeting shall be considered at such meeting.  Any adjourned
meeting may be held as adjourned without further notice.

     9.4.  Record Date for Meetings.  For the purpose of determining the
           ------------------------                                     
Shareholders who are entitled to notice of and to vote at any meeting, or to
participate in any distribution, or for the purposes of any other action, the
Trustees may from time to time close the transfer books for such period, not
exceeding 30 days, as the Trustees may determine; or without closing the
transfer books the Trustees may fix a date not more than 60 days prior to the
date of any meeting of Shareholders or daily dividends or other action as a
record date for the determination of the Persons to be treated as Shareholders
of record for such purposes, except for dividend payments which shall be
governed by Section 8.2 hereof.

     9.5.  Proxies, etc.  At any meeting of Shareholders, any holder of Shares
           -------------                                                       
entitled to vote thereat may vote by proxy, provided that no proxy shall be
voted at any meeting unless it shall have been placed on file with the
Secretary, or with such other officer or agent of the Trust as the Secretary may
direct, for verification prior to the time at which such vote shall be taken.
Pursuant to a resolution of a majority of the Trustees, proxies may be solicited
in the name of one or more Trustees or one or more of the officers of the Trust.
Only Shareholders of record shall be entitled to vote.  Each full Share shall be
entitled to one vote and fractional Shares shall be entitled to a vote of such
fraction.  When any Share is held jointly by several persons, any one of them
may vote at any meeting in person or by proxy in respect of such Share, but if
more than one of them shall be present at such meeting in person by proxy, and
such joint owners or their proxies so present disagree as to any vote to be
cast, such vote shall not be received in respect of such Share.  A proxy
purporting to be executed by or on behalf of a Shareholder shall be deemed valid
unless challenged at or prior to its exercise, and the burden of proving
invalidity shall rest on the challenger.  If the holder of any such Share is a
minor or a person of unsound mind, and subject to guardianship or to the legal
control of any other person as regards the charge or management of such Share,
he may vote by his guardian or such other person appointed or having such
control, and such vote may be given in person or by proxy.

     9.6.  Reports.  The Trustees shall cause to be prepared at least annually a
           -------                                                              
report of operations containing a balance sheet and statement of income and
undistributed income of the Trust prepared in conformity with generally accepted
accounting principles and an opinion of an independent public accountant on such
financial statements. Copies of such reports shall be mailed to all Shareholders
of record within the time required by the 1940 Act, and in any event within a
reasonable period preceding the annual meeting of Shareholders. The Trustees
shall, in addition, furnish to the Shareholders at least semi-annually interim
reports containing an

                                       17
<PAGE>
 
unaudited balance sheet of the Trust as of the end of such period and an
unaudited statement of income and surplus for the period from the beginning of
the current fiscal year to the end of such period.

     9.7.  Inspection of Records.  The records of the Trust shall be open to
           ---------------------                                            
inspection by Shareholders to the same extent as is permitted shareholders of a
Massachusetts business corporation.

     9.8.  Shareholder Action by Written Consent.  Any action which may be taken
           -------------------------------------                                
by Shareholders may be taken without a meeting if a majority of Shareholders
entitled to vote on the matter (or such larger proportion thereof as shall be
required by any express provision of this Declaration) consent to the action in
writing and the written consents are filed with the records of the meetings of
Shareholders.  Such consent shall be treated for all purposes as a voice taken
at a meeting of Shareholders.

provisions of Section 10.2 hereof, the Trust created hereby shall continue
without limitation of time.

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

          (a) The Trust may be terminated by the affirmative vote of the holders

             (i) The Trust shall carry on no business except for the purpose of
     winding up its affairs.

             (ii) The Trustees shall proceed to wind up the affairs of the Trust
     and all of the powers of the Trustees under this Declaration shall continue
     until the affairs of the Trust shall have been wound up, including the
     power to fulfill or discharge the contracts of the Trust, collect its
     assets, sell, convey, assign, exchange, transfer or otherwise dispose of
     all or any part of the remaining Trust Property to one or more persons at
     public or private sale for consideration which may consist in whole or in
     part of cash, securities or other property of any kind, discharge or pay
     its liabilities, and do all other acts appropriate to liquidate its
     business.

             (iii)  After paying or adequately providing for the payment of all
     liabilities, and upon receipt of such releases, indemnities and refunding
     agreements, as they deem necessary for their protection, the Trustees may
     distribute the remaining Trust Property, in cash or in kind or partly each,
     among the Shareholders of each class, according to their respective rights
     taking into account the proper allocation of expenses being borne solely by
     any class of Shares.

all further liabilities and duties hereunder, and the rights and interests of
all Shareholders shall thereupon cease.

     10.3.  Amendment Procedure.
            ------------------- 

          (a) Except as provided in paragraph (b) of this Section 10.3, this
Declaration may be amended by a vote of a majority of the Shares at a meeting of
Shareholders, or by an instrument in writing, without a meeting signed by a
majority of the Trustees and consented to by the holders of not less than a
majority of such Shares.  The Trustees may also amend this Declaration without
the vote or consent of Shareholders  to change the name of the Trust, (ii) to
supply any omission, or cure, correct or supplement any ambiguous, defective or
inconsistent provision hereof, (iii) if they deem it necessary to conform this
Declaration to the requirements of applicable federal or state laws or
regulations or the requirements of the Internal Revenue Code, or to eliminate or
reduce any federal, state or local taxes which are or may be payable by the
Trust or the Shareholders, but the Trustees shall not be liable for failing to
do so, (iv) to make any changes deemed necessary to effectuate the designations
and powers, preferences and rights, and the qualifications, limitations and
restrictions adopted by the Trustees with respect to the Preferred Shares

adversely affect the rights of any Shareholder with respect to which the
amendment is or purports to be applicable.

          (b) No amendment may be made, under Section 10.3 (a) above, which
would change any rights with respect to any Shares of the Trust by reducing the
amount payable thereon upon liquidation of the trust or by diminishing or
eliminating any voting rights pertaining thereto, except with the vote or
consent of the holders of two-thirds of the Shares of the Trust so affected
outstanding and entitled to vote. Nothing contained in this Declaration shall
permit the amendment of this Declaration to impair the exemption from personal
liability of the Shareholders, Trustees, officers, employees and agents of the
Trust or to permit assessments upon Shareholders.

          (c) A certification in recordable form signed by a majority of the
Trustees or by the Secretary or any Assistant Secretary of the Trust setting
forth an amendment and reciting that it was duly adopted by the Shareholders or
by the Trustees as aforesaid or a copy of the Declaration, as amended, in
recordable form, and executed by a majority of the Trustees or certified by the
Secretary or any Assistant Secretary of the Trust, shall be conclusive evidence
of such amendment when lodged among the records of the Trust.

          Notwithstanding any other provision hereof, until such time as a
Registration Statement under the Securities Act of 1933, as amended, covering
the first public offering of Shares of the Trust shall have become effective,
this Declaration may be terminated or amended in any respect by the affirmative
vote of a majority of the trustees or by an instrument signed by a majority of
the Trustees.

entitled to be voted on the matter shall be required to approve, adopt or
authorize (i) a merger or consolidation or share exchange of the Trust with any

authorized by the affirmative vote of at least two-thirds of the total number of
Trustees fixed in accordance with this Declaration, in which case the
affirmative vote of the holders of a majority of the outstanding Shares of the
Trust entitled to vote thereon shall be required.  In respect of any such
merger, consolidation, sale or exchange of assets, any Shareholder shall be
entitled to rights of appraisal of his Shares to the same extent as a
Shareholder of a Massachusetts business corporation in respect of a merger,
consolidation, sale or exchange of assets of a Massachusetts business
corporation, and such right shall be his exclusive remedy in respect of his
dissent from any such action.

     10.5  Conversion to Open-End Company.  Notwithstanding any other provisions
           ------------------------------                                       
of this Declaration or the By-Laws of the Trust, a favorable vote of the holders
of two-thirds of the outstanding  Shares of the Trust entitled to be voted on
the matter shall be required to approve, adopt or authorize any amendment to
this Declaration that makes the Common Shares a "redeemable security" as that
term is defined in section 2(a)(32) the 1940 Act) unless such action has
previously been  approved, adopted or authorized by the affirmative vote of at
least two-thirds of the total number of Trustees fixed in accordance with this
Declaration, in which case the affirmative vote of the holders of a majority of
the outstanding Shares of the Trust entitled to vote thereon shall be required.

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

corporation or corporations under the laws of any jurisdiction or any other
trust, partnership, association or other organization to take over all of the
Trust Property or to carry on any business in which the Trust shall directly or
indirectly have any interest, and to sell, convey and transfer the Trust
Property to any such corporation, trust, association or organization in exchange
for the Shares or securities thereof or otherwise, and to lend money to,
subscribe for the Shares or securities of, and enter into any contracts with any
such corporation, trust, partnership, association or organization, or any
corporation, partnership, trust, association or organization in which the Trust
holds or is about to acquire shares or any other interest. The Trustees may also
cause merger or consolidation between the Trust or any successor thereto and any
such corporation, trust, partnership, association or other organization if and
to the extent permitted by law, as provided under the law then in effect.
Nothing contained herein shall be construed as requiring approval of
Shareholders for the Trustees to organize or assist in organizing one or more
corporations, trusts, partnerships, associations or other organizations and
selling, conveying or transferring a portion of the Trust Property to such
organizations or entities.

several counterparts, each of which shall be deemed to be an original, and such
counterparts, together, shall constitute one and the same instrument, which
shall be sufficiently evidenced by any such original counterpart.

     11.5  Reliance by Third Parties.  Any certificate executed by an individual
           -------------------------

     11.6  Provisions in Conflict With Law or Regulations.
           ---------------------------------------------- 

          (a) The provisions of this Declaration are severable, and if the
Trustees shall determine, with the advice of counsel, that any of such
provisions is in conflict with the 1940 Act, the regulated investment company
provisions of the Internal Revenue Code or with other applicable laws and
regulations, the conflicting provision shall be deemed never to have constituted
a part of this Declaration; provided, however, that such determination shall not
affect any of the remaining provisions of this Declaration or render invalid or
improper any action taken or omitted prior to such determination.

          (b) If any provision of this Declaration shall be held invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall
attach only to such provision in such jurisdiction and shall not in any manner
affect such provision in any other jurisdiction or any other provision of this
Declaration in any jurisdiction.

by duly executed proxy and each full share represented at the meeting shall have
one vote, all as provided in Article IX of the Declaration.  No proxy shall be
valid after eleven (11) months from the date of its execution, unless a longer
period is expressly stated in such proxy.

     Section 1.3.  Closing of Transfer Books and Fixing Record Dates.  For the
                   -------------------------------------------------          
purpose of determining the Shareholders who are entitled to notice of or to vote
or act at any meeting, including any adjournment thereof, or who are entitled to
participate in any distribution, or for the purposes of any other action, the
Trustees may from time to time close the transfer books or
<PAGE>
 
fix a record date in the manner provided in Section 9.4 of the
Declaration.  If the Trustees do not prior to any meeting of Shareholders so fix

case may be, shall be the record date.

     Section 1.4.  Inspectors of Election.  In advance of any meeting of
                   ----------------------                               
Shareholders, the Trustees may appoint Inspectors of Election to act at the
meeting or any adjournment thereof.  If Inspectors of Election are not so
appointed, the Chairman, if any, of any meeting of Shareholders may, and on the
request of any Shareholder or his proxy shall, appoint Inspectors of Election of
the meeting.  The number of Inspectors shall be either one or three.  If
appointed at the meeting on the request of one or more Shareholders or proxies,
a majority of Shares present shall determine whether one or three Inspectors are
to be appointed, but failure to allow such determination by the Shareholders
shall not affect the validity of the appointment of Inspectors of Election.  In
case any person appointed as Inspector fails to appear or fails or refuses to
act, the vacancy may be filled by appointment made by the Trustees in advance of
the convening of the meeting or at the meeting by the person acting as chairman.
The Inspectors of Election shall determine the number of Shares outstanding, the
Shares represented at the meeting, the existence of a quorum, the authenticity,
validity and effect of proxies, shall receive votes, ballots or consents, shall
hear and determine all challenges and questions in any way arising in connection
with the right to vote, shall count and tabulate all votes or consents,
determine the results, and do such other acts as may be proper to conduct the
election or vote with fairness to all Shareholders.  If there are three
Inspectors of Election, the decision, act or certificate of a majority is
effective in all respects as the decision, act or certificate of all. On request
of the Chairman, if any, of the meeting, or of any Shareholder or his proxy, the
Inspectors of Election shall make a report in
<PAGE>
 
writing of any challenge or question or matter determined by them and shall
execute a certificate of any facts found by them.

Trust, as of the record date of the meeting or the date of closing of transfer
books, as the case may be. Such list of Shareholders shall contain the name of
each Shareholder in alphabetical order and the address of and number of Shares
owned by such Shareholder. Shareholders shall have such other rights and
procedures of inspection of the books and records of the Trust as are granted to
shareholders of a Massachusetts business corporation.
