  MuniHoldings Florida Insured Fund IV (the "Fund") is a recently 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 whose value 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.

                                OFFERING SUMMARY
 
  This summary is qualified in its entirety by reference to the detailed
information included in this prospectus and the statement of additional
information.
 
THE OFFERING    The Fund is offering a total of     Series A AMPS and     Se-
                ries B AMPS, each at a purchase price of $25,000 per share plus
                accumulated dividends, if any, from the date the shares are
                first issued. The AMPS are being offered by Merrill Lynch,
                Pierce, Fenner & Smith Incorporated, as underwriter.
 
                The AMPS of each series will be preferred shares of the Fund
                that entitle their holders to receive cash dividends at an an-
                nual rate that may vary for the successive dividend periods for
                each series. In general, except as described below, each divi-
                dend period for each series of AMPS following the initial divi-
                dend period will be seven days. The applicable dividend for a
                particular dividend period will be determined by an auction
                conducted on the business day next preceding the start of that
                dividend period.
 
                Investors and potential investors in AMPS of each series may
                participate in auctions for the AMPS through their broker-deal-
                ers.
 
                Generally, AMPS investors will not receive certificates repre-
                senting ownership of their shares. Ownership of AMPS will be
                maintained in book-entry form by the securities depository (The
                Depository Trust Company) or its nominee for the account of the
                investor's agent member (generally the investor's broker-deal-
                er). The investor's agent member, in turn, will maintain rec-
                ords of such investor's beneficial ownership of AMPS.
 
DIVIDENDS AND   Dividends on the Series A AMPS and Series B AMPS will be cumu-
DIVIDEND        lative from the date the shares are first issued and payable
PERIODS         beginning on       , 1999 in the case of Series A AMPS and
                 , 1999 in the case of Series B AMPS. Thereafter, in the case
                of dividend periods that are not special dividend periods, div-
                idends generally will be payable on each succeeding      in the
                case of Series A AMPS and each succeeding      in the case of
                Series B AMPS. After the initial dividend period, each dividend
                period for each series of AMPS will generally consist of seven
                days; provided, however, that before any auction, the Fund may
                decide, subject to certain limitations and only if it gives no-
                tice to holders, to declare a special dividend period of up to
                five years.
 
                Dividends for each series of AMPS will be paid through the se-
                curities depository (The Depository Trust Company) on each div-
                idend payment date for each series.
 
                The cash dividend rate on the Series A AMPS for the initial
                dividend period ending       , 1999 will be  % per year and the
                cash dividend rate on the Series B AMPS for the initial divi-
                dend period ending       , 1999 will be  % per year. For each
                subsequent dividend period, the auction agent (IBJ Whitehall
                Bank & Trust Company) will hold an auction to determine the
                cash dividend rate on the shares of each series of AMPS.
 
DETERMINATION   Generally, the applicable dividend rate for any dividend period
OF MAXIMUM      for AMPS of each series will be subject to a maximum applicable
DIVIDEND        rate. The maximum applicable rate for AMPS will depend on the
RATES           credit rating assigned to the shares and on the length of the
                dividend period. There is no minimum applicable dividend rate
                for any dividend period.

ASSET           Under the Fund's Certificate of Designation creating the AMPS,
MAINTENANCE     the Fund must maintain
 
                . asset coverage of the AMPS as required by the rating agencies
                  rating the AMPS, and
 
                . asset coverage of the AMPS of at least 200% as required by
                  the Investment Company Act of 1940.
 
                The Fund estimates that, based on the composition of its port-
                folio at       , 1999, asset coverage of the AMPS as required
                by the Investment Company Act of 1940 would be approximately  %
                immediately after the Fund issues the AMPS offered by this pro-
                spectus representing approximately  % of the Fund's capital.
 
MANDATORY
REDEMPTION      If the required asset coverage is not maintained or, when
                necessary, restored, the Fund must redeem AMPS at the price of
                $25,000 per share plus accumulated but unpaid dividends thereon
                (whether or not earned or declared). The provisions of the
                Investment Company Act of 1940 may restrict the Fund's ability
                to make such a mandatory redemption.
 
OPTIONAL        The Fund may, at its option, choose to redeem all or a portion
REDEMPTION      of the AMPS of each series on any dividend payment date at the
                price of $25,000 per share, plus accumulated but unpaid
                dividends thereon (whether or not earned or declared) plus any
                applicable premium.
 
LIQUIDATION
PREFERENCE      The liquidation preference (that is, the amount the Fund must
                pay to AMPS shareholders if the Fund is liquidated) of each
                share of AMPS will be $25,000, plus an amount equal to accumu-
                lated but unpaid dividends (whether or not earned or declared).
 
RATINGS         The AMPS will be issued with a rating of "aaa" from Moody's In-
                vestors Service, Inc. and AAA from Standard & Poor's.
 
VOTING RIGHTS
                The Investment Company Act of 1940 requires that the holders of
                AMPS and any other preferred shares, voting as a separate
                class, have the right to elect at least two trustees at all
                times and to elect a majority of the trustees at any time when
                dividends on the AMPS or any other preferred shares are unpaid
                for two full years. The Fund's Declaration of Trust and the In-
                vestment Company Act of 1940 require holders of AMPS and any
                other preferred shares to vote as a separate class on certain
                other matters.

                    RISK FACTORS AND SPECIAL CONSIDERATIONS
 
  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 income 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 to any single economic, political or regulatory occurrence than a more
widely-diversified fund.
 
  Rating Categories. The Fund intends to invest in municipal bonds that are
rated investment grade by Standard & Poor's, Moody's Investors Service, Inc. or
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 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.
 
  Portfolio Insurance. The Fund will be subject to certain restrictions on
investments imposed by guidelines of the insurance companies issuing the
portfolio insurance. The Fund does not expect these guidelines to prevent the
Fund's investment adviser from managing the Fund's portfolio in accordance with
the Fund's investment objective and policies.
 
  Indexed and Inverse Floating Rate Securities. The Fund may invest in
securities whose potential returns are directly related to changes in an
underlying index or interest rate, known as indexed securities. The return on
indexed securities will rise when the underlying index or interest rate rises
and fall when the index or interest rate falls. The Fund may also invest in
securities whose return is inversely related to changes in an interest rate
(inverse floaters). In general, income on inverse floaters will decrease when
short term interest rates increase and increase when short term interest rates
decrease. Investments in inverse floaters may subject the Fund to the risks of
reduced or eliminated interest payments and 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 the 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, intend to enter into options and futures
transactions for speculative purposes. The Fund is not required to hedge its
portfolio 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 discourage a third party from seeking to obtain control of the Fund.
 
                                       5
<PAGE>
 
 
  Investment Considerations. Investors in AMPS should consider the following
factors:
 
  . The credit ratings of the AMPS could be reduced while an investor holds
    the AMPS.
 
  . Neither broker-dealers nor the Fund are obligated to purchase AMPS in an
    auction or otherwise nor is the Fund required to redeem shares of AMPS in
    the event of a failed auction.
 
  . If sufficient bids do not exist in an auction, the applicable dividend
    rate will be the maximum applicable dividend rate, and in such event,
    owners of AMPS wishing to sell will not be able to sell all, and may not
    be able to sell any, AMPS in the auction. As a result, investors may not
    have liquidity of investment.
 
  Secondary Market. The broker-dealers intend to maintain a secondary trading
market in the AMPS outside of auctions; however, they have no obligation to do
so and there can be no assurance that a secondary market for the AMPS will
develop or, if it does develop, that it will provide holders with a liquid
trading market. The AMPS will not be registered on any stock exchange or on any
automated quotation system. An increase in the level of interest rates likely
will have an adverse effect on the secondary market price of the AMPS, and a
selling shareholder may have to sell AMPS between auctions at a price per share
of less than $25,000.

                                   THE FUND
 
  MuniHoldings Florida Insured Fund IV (the "Fund") is a recently 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 commenced operations on January   , 1999 upon the closing of an
initial public offering of its Common Shares. The proceeds of such offering
were approximately $   after the payment of organizational and offering
expenses.
 
                                USE OF PROCEEDS
 
  The estimated net proceeds of this offering will be $   after the payment of
offering expenses (estimated to be $  ) and the sales load and the payment to
the Fund by Merrill Lynch, Pierce Fenner & Smith, Incorporated ("Merrill
Lynch" or the "Underwriter") to cover certain expenses. See "Underwriting."
 
  The net proceeds of the offering will be invested in accordance with the
Fund's investment objective and policies during a period estimated not to
exceed three months from the offer and sale of such shares of AMPS 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 and income tax and the opportunity to own shares
whose value is exempt from Florida intangible personal property tax. The Fund
seeks to achieve its investment 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 which, in
the opinion of bond counsel to the issuer, is exempt from Federal income tax
and which enables shares of the Fund to be exempt from Florida intangible
personal property tax ("Florida Municipal Bonds"). The Fund intends to invest
substantially all (at least 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 that are exempt from
Federal income taxes but whose value 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,
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 in the statement of additional information 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 options and futures transactions to reduce volatility in
the net asset value of its shares of 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
 
                                       8
<PAGE>
 
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.
 
  The investment grade Florida Municipal Bonds and Municipal Bonds in which
the Fund will primarily invest are those Florida Municipal Bonds and Municipal
Bonds that are rated at the date of purchase in the four highest rating
categories of S&P, 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-l+
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-l+ through F-3 for Fitch. Obligations ranked in the lowest investment
grade 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. Appendix B to the statement of additional information contains a
description of S&P's, Moody's and Fitch's ratings of Florida Municipal Bonds
and Municipal Bonds. In assessing the 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 enhancement to which particular
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, such as that used by the Fund.
 
                                       9
<PAGE>
 
  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 have significant
assets subject to Florida intangible personal property tax. For a more
complete description of Florida Municipal Bonds and Municipal Bonds, see
"Investment Objective and Policies" in the statement of additional
information.
 
  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" herein and in the statement of additional
information. 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 obligations 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 available.
See Appendix C to the statement of additional information 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 or 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 or
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.
 
                                      10
<PAGE>
 
  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.
 
  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. 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 which are not in default. In certain circumstances, however, the
Investment Adviser may determine that an alternative 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 will be unable to
manage the portfolio to the extent it holds defaulted securities, which may
limit its ability in certain circumstances to purchase other Florida Municipal
Bonds and Municipal Bonds. See "Net Asset Value" in the statement of
additional information 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 may 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 the
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).
 
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
 
                                      11
<PAGE>
 
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, 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. According to the Florida General
Purposes Financial Statements for the fiscal year ended 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. For a discussion of economic and other conditions in the
State of Florida, see Appendix A, "Economic and Other Conditions in Florida"
to the statement of additional information.
 
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 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 in the secondary market
synthetically-created inverse floating rate bonds evidenced by custodial or
trust receipts. Generally, income on inverse floating rate bonds will decrease
when short-term interest rates increase, and will increase when short-term
interest rates decrease. Such securities have the effect of providing a degree
of investment leverage, since they may increase or decrease in value in
response to changes, as an illustration, in market interest rates at a rate
that is a multiple (typically two) of the rate at which fixed-rate, long-term,
tax-exempt securities increase or decrease in response
 
                                      12
<PAGE>
 
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 Florida Municipal Bonds,
Municipal Bonds and U.S. Government 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.
 
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 and options thereon. 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. For so long as the AMPS are rated by Moody's and S&P, the Fund's
use of options and financial futures contracts will be subject to the
limitations described under "Rating Agency Guidelines" herein and in the
statement of additional information. Furthermore, the Fund 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. The Fund has no
obligation to enter into hedging transactions and may not do so.
 
  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 the statement of
additional information. In addition, in order to obtain ratings of the
preferred shares from one or more nationally recognized statistical rating
organizations ("NRSROs"), the Fund may be required to limit its use of hedging
techniques in accordance with the specified guidelines of such rating
organizations.
 
  For 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, see "Investment Objective and Policies--
Options and Futures Transactions" in the statement of additional information.
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.

                              DESCRIPTION OF AMPS
 
GENERAL
 
  Certain of the capitalized terms used herein are defined in the Glossary
that appears at the back of this prospectus.
 
  The AMPS of each series will be preferred shares that entitle their holders
to receive dividends when, as and if declared by the Board of Trustees, out of
funds legally available therefor, at a rate per annum that may vary for the
successive Dividend Periods for each such series. After the Initial Dividend
Period, each Subsequent Dividend Period for each series of AMPS generally will
be a 7-Day Dividend Period; provided, however, that prior to any Auction, the
Fund may elect, subject to certain limitations described herein, upon giving
notice to holders thereof, a Special Dividend Period. The Applicable Rate for
a particular Dividend Period will be determined by an Auction conducted on the
Business Day before the start of such Dividend Period. Beneficial Owners and
Potential Beneficial Owners of AMPS may participate in Auctions therefor,
although, except in the case of a Special Dividend Period, Beneficial Owners
desiring to continue to hold all of their AMPS regardless of the Applicable
Rate resulting from Auctions need not participate. For an explanation of
Auctions and the method of determining the Applicable Rate, see "The Auction"
herein and in the statement of additional information.
 
  The following is a brief description of the terms of the AMPS. This
description does not purport to be complete and is subject to and qualified in
its entirety by reference to the Fund's Declaration of Trust and Certificate
of Designation, including the provisions thereof establishing the AMPS. The
Fund's Declaration of Trust and the form of Certificate of Designation
establishing the terms of the AMPS have been filed as exhibits to the
Registration Statement of which this prospectus is a part.
 
DIVIDENDS
 
  General. The holders of shares of each series of AMPS will be entitled to
receive, when, as and if declared by the Board of Trustees of the Fund, out of
funds legally available therefor, cumulative cash dividends on their shares,
at the Applicable Rate determined as set forth below under "Determination of
Dividend Rate," payable on the respective dates set forth below. Dividends on
the AMPS so declared and payable shall be paid (i) in preference to and in
priority over any dividends so declared and payable on the Common Shares, and
(ii) to the extent permitted under the Code and to the extent available, out
of net tax-exempt income earned on the Fund's investments. Generally,
dividends on AMPS, to the extent that they are derived from interest paid on
Municipal Bonds, will be exempt from Federal income taxes, subject to possible
application of the alternative minimum tax. See "Taxes" in the statement of
additional information.
 
  Dividends on the AMPS will accumulate from the date on which the Fund
originally issues the shares of AMPS (the "Date of Original Issue") and will
be payable on each series of AMPS on the dates described below. Dividends on
shares of each series of AMPS with respect to the Initial Dividend Period
shall be payable on the Initial Dividend Payment Date with respect to each
series of AMPS. Following the Initial Dividend Payment Date for each series of
AMPS, dividends on each series of AMPS will be payable, at the option of the
Fund, either (i) with respect to any 7-Day Dividend Period and any Short Term
Dividend Period of 35 or fewer days, on the day next succeeding the last day
thereof or (ii) with respect to any Short Term Dividend Period of more than 35
days and with respect to any Long Term Dividend Period, monthly on the first
Business Day of each calendar month during such Short Term Dividend Period or
Long Term Dividend Period and on the day next succeeding the last day thereof
(each such date referred to in clause (i) or (ii) being referred to herein as
a "Normal Dividend Payment Date"), except that if such Normal Dividend Payment
Date is not a Business Day, the Dividend Payment Date shall be the first
Business Day next succeeding such Normal Dividend Payment Date. Thus,
following the Initial Dividend Payment Date for each series of AMPS, dividends
generally will be payable (in the case of Dividend Periods which are not
Special Dividend Periods) on each succeeding      in the case of Series A AMPS
and on each succeeding      in the case of Series B AMPS. Although any
 
                                      14
<PAGE>
 
particular Dividend Payment Date may not occur on the originally scheduled
date because of the exceptions discussed above, the next succeeding Dividend
Payment Date, subject to such exceptions, will occur on the next following
originally scheduled date. If for any reason a Dividend Payment Date cannot be
fixed as described above, then the Board of Trustees shall fix the Dividend
Payment Date. The Board of Trustees by resolution prior to authorization of a
dividend by the Board of Trustees may change a Dividend Payment Date if such
change does not adversely affect the contract rights of the holders of AMPS
set forth in the Declaration of Trust. The Initial Dividend Period, 7-Day
Dividend Periods and Special Dividend Periods are hereinafter sometimes
referred to as "Dividend Periods." Each dividend payment date determined as
provided above is hereinafter referred to as a "Dividend Payment Date."
 
  Prior to each Dividend Payment Date, the Fund is required to deposit with
the Auction Agent sufficient funds for the payment of declared dividends. The
Fund does not intend to establish any reserves for the payment of dividends.
 
  Each dividend will be paid to the record holder of the AMPS, which holder is
expected to be the nominee of the Securities Depository. See "The Auction--
Securities Depository." The Securities Depository will credit the accounts of
the Agent Members of the Existing Holders in accordance with the Securities
Depository's normal procedures which provide for payment in same-day funds.
The Agent Member of an Existing Holder will be responsible for holding or
disbursing such payments on the applicable Dividend Payment Date to such
Existing Holder in accordance with the instructions of such Existing Holder.
Dividends in arrears for any past Dividend Period may be declared and paid at
any time, without reference to any regular Dividend Payment Date, to the
nominee of the Securities Depository. Any dividend payment made on AMPS first
shall be credited against the earliest declared but unpaid dividends
accumulated with respect to such series.
 
  Holders of AMPS will not be entitled to any dividends, whether payable in
cash, property or stock, in excess of full cumulative dividends except as
described under "Additional Dividends" and "Non-Payment Period; Late Charge."
No interest will be payable in respect of any dividend payment or payments on
the shares of AMPS which may be in arrears.
 
  The amount of cash dividends per share of any series of AMPS payable (if
declared) on the Initial Dividend Payment Date, each 7-Day Dividend Period and
each Dividend Payment Date of each Short Term Dividend Period shall be
computed by multiplying the Applicable Rate for such Dividend Period by a
fraction, the numerator of which will be the number of days in such Dividend
Period or part thereof that such share was outstanding and for which dividends
are payable on such Dividend Payment Date and the denominator of which will be
365, multiplying the amount so obtained by $25,000, and rounding the amount so
obtained to the nearest cent. During any Long Term Dividend Period, the amount
of cash dividends per share of AMPS payable (if declared) on any Dividend
Payment Date shall be computed by multiplying the Applicable Rate for such
Dividend Period by a fraction, the numerator of which will be such number of
days in such part of such Dividend Period that such share was outstanding and
for which dividends are payable on such Dividend Payment Date and the
denominator of which will be 360, multiplying the amount so obtained by
$25,000, and rounding the amount so obtained to the nearest cent.
 
  Notification of Dividend Period. With respect to each Dividend Period that
is a Special Dividend Period, the Fund, at its sole option and to the extent
permitted by law, by telephonic and written notice (a "Request for Special
Dividend Period") to the Auction Agent and to each Broker-Dealer, may request
that the next succeeding Dividend Period for a series of AMPS will be a number
of days (other than seven), evenly divisible by seven, and not fewer than
seven nor more than 364 in the case of a Short Term Dividend Period or one
whole year or more but not greater than five years in the case of a Long Term
Dividend Period, specified in such notice, provided that the Fund may not give
a Request for Special Dividend Period (and any such request shall be null and
void) unless, for any Auction occurring after the initial Auction, Sufficient
Clearing Bids were made in the last occurring Auction and unless full
cumulative dividends, any amounts due with respect to redemptions, and any
Additional Dividends payable prior to such date have been paid in full. Such
Request for Special Dividend Period, in the case of a Short Term Dividend
Period, shall be given on or prior to the second Business Day but
 
                                      15
<PAGE>
 
not more than seven Business Days prior to an Auction Date for the AMPS and,
in the case of a Long Term Dividend Period, shall be given on or prior to the
second Business Day but not more than 28 days prior to an Auction Date for the
AMPS. Upon receiving such Request for Special Dividend Period, the Broker-
Dealers jointly shall determine whether, given the factors set forth below, it
is advisable that the Fund issue a Notice of Special Dividend Period for a
series of AMPS as contemplated by such Request for Special Dividend Period and
the Optional Redemption Price of the AMPS during such Special Dividend Period
and the Specific Redemption Provisions and shall give the Fund and the Auction
Agent written notice (a "Response") of such determination by no later than the
second Business Day prior to such Auction Date. In the event the Response
indicates that it is advisable that the Fund give a notice of a Special
Dividend Period for the AMPS, the Fund, by no later than the second Business
Day prior to such Auction Date may give a notice (a "Notice of Special
Dividend Period") to the Auction Agent, the Securities Depository and each
Broker-Dealer. See "Description of AMPS--Dividends-- Notification of Dividend
Period" in the statement of additional information for a detailed description
of these procedures.
 
  Determination of Dividend Rate. The dividend rate on shares of each series
of AMPS during the period from and including the Date of Original Issue for
each series of AMPS to but excluding the Initial Dividend Payment Date for
each series of AMPS (the "Initial Dividend Period") will be the rate per annum
set forth above under "Offering Summary." Commencing on the Initial Dividend
Payment Date for each series of AMPS, the Applicable Rate on the shares of
such series of AMPS for each Subsequent Dividend Period, which Subsequent
Dividend Period shall be a period commencing on and including a Dividend
Payment Date and ending on and including the calendar day prior to the next
Dividend Payment Date (or last Dividend Payment Date in a Dividend Period if
there is more than one Dividend Payment Date), shall be equal to the rate per
annum that results from the Auction with respect to such Subsequent Dividend
Period. The Initial Dividend Period and Subsequent Dividend Period for each
series of AMPS is referred to herein as a "Dividend Period." Cash dividends
shall be calculated as set forth above under "Dividends--General."
 
  Restrictions on Dividends and Other Payments. Under the 1940 Act, the Fund
may not declare dividends or make other distributions on Common Shares or
purchase any such shares if, at the time of the declaration, distribution or
purchase, as applicable (and after giving effect thereto), asset coverage (as
defined in the 1940 Act) with respect to the outstanding AMPS would be less
than 200% (or such other percentage as in the future may be required by law).
The Fund estimates that, based on the composition of its portfolio at       ,
1999, asset coverage with respect to AMPS would be approximately 250%
immediately after the issuance of the AMPS offered hereby. Under the Code, the
Fund, among other things, must distribute at least 90% of its investment
company taxable income each year in order to maintain its qualification for
tax treatment as a regulated investment company. The foregoing limitations on
dividends, distributions and purchases under certain circumstances may impair
the Fund's ability to maintain such qualification. See "Taxes" in the
statement of additional information.
 
  Upon any failure to pay dividends on AMPS for two years or more, the holders
of the AMPS will acquire certain additional voting rights. See "Voting Rights"
below. Such rights shall be the exclusive remedy of the holders of AMPS upon
any failure to pay dividends on shares of the Fund.
 
  Additional Dividends. If the Fund retroactively allocates any net capital
gains or other income subject to regular Federal income taxes to shares of
AMPS without having given advance notice thereof to the Auction Agent as
described under "The Auction--Auction Date; Advance Notice of Allocation of
Taxable Income; Inclusion of Taxable Income in Dividends" below, which may
only happen when such allocation is made as a result of the redemption of all
or a portion of the outstanding AMPS or the liquidation of the Fund (the
amount of such allocation referred to herein as a "Retroactive Taxable
Allocation"), the Fund, within 90 days (and generally within 60 days) after
the end of the Fund's fiscal year for which a Retroactive Taxable Allocation
is made, will provide notice thereof to the Auction Agent and to each holder
of shares (initially Cede as nominee of the Securities Depository) during such
fiscal year at such holder's address as the same appears or last appeared
 
                                      16
<PAGE>
 
on the stock books of the Fund. The Fund, within 30 days after such notice is
given to the Auction Agent, will pay to the Auction Agent (who then will
distribute to such holders of AMPS), out of funds legally available therefor,
an amount equal to the aggregate Additional Dividend (as defined below) with
respect to all Retroactive Taxable Allocations made to such holders during the
fiscal year in question. See "Taxes" in the statement of additional
information.
 
  An "Additional Dividend" means payment to a present or former holder of
shares of AMPS of an amount which, when taken together with the aggregate
amount of Retroactive Taxable Allocations made to such holder with respect to
the fiscal year in question, would cause such holder's dividends in dollars
(after Federal income tax consequences) from the aggregate of both the
Retroactive Taxable Allocations and the Additional Dividend to be equal to the
dollar amount of the dividends which would have been received by such holder
if the amount of the aggregate Retroactive Taxable Allocations had been
excludable from the gross income of such holder. Such Additional Dividend
shall be calculated (i) without consideration being given to the time value of
money; (ii) assuming that no holder of AMPS is subject to the Federal
alternative minimum tax with respect to dividends received from the Fund; and
(iii) assuming that each Retroactive Taxable Allocation would be taxable in
the hands of each holder of AMPS at the greater of: (a) the maximum combined
marginal regular Federal individual income tax rate applicable to ordinary
income or capital gains depending on the taxable character of the distribution
(including any surtax); or (b) the maximum combined marginal regular Federal
and Florida corporate income tax rate applicable to ordinary income or capital
gains depending on the taxable character of the distribution (taking into
account in both (a) and (b) the Federal income tax deductibility of state
taxes paid or incurred but not any phase out of, or provision limiting,
personal exemptions, itemized deductions, or the benefit of lower tax brackets
and assuming the taxability of Federally tax-exempt dividends for corporations
for Florida state franchise tax purposes). Although the Fund generally intends
to designate any Additional Dividend as an exempt-interest dividend to the
extent permitted by applicable law, it is possible that all or a portion of
any Additional Dividend will be taxable to the recipient thereof. See "Taxes--
Tax Treatment of Additional Dividends" in the statement of additional
information. The Fund will not pay a further Additional Dividend with respect
to any taxable portion of an Additional Dividend.
 
  If the Fund does not give advance notice of the amount of taxable income to
be included in a dividend on AMPS in the related Auction, the Fund may include
such taxable income in a dividend on shares of AMPS if it increases the
dividend by an additional amount calculated as if such income were a
Retroactive Taxable Allocation and the additional amount were an Additional
Dividend and notifies the Auction Agent of such inclusion at least five days
prior to the applicable Dividend Payment Date. See "The Auction--Auction
Procedures--Auction Date; Advance Notice of Allocation of Taxable Income;
Inclusion of Taxable Income in Dividends" below.
 
ASSET MAINTENANCE
 
  The Fund will be required to satisfy two separate asset maintenance
requirements under the terms of the Certificate of Designation. These
requirements are summarized below.
 
  1940 Act AMPS Asset Coverage. The Fund will be required under the
Certificate of Designation to maintain, with respect to AMPS, as of the last
Business Day of each month in which any AMPS are outstanding, asset coverage
of at least 200% with respect to senior securities which are stock, including
the AMPS (or such other asset coverage as in the future may be specified in or
under the 1940 Act as the minimum asset coverage for senior securities which
are stock of a closed-end investment company as a condition of paying
dividends on its common stock) ("1940 Act AMPS Asset Coverage"). If the Fund
fails to maintain 1940 Act AMPS Asset Coverage and such failure is not cured
as of the last Business Day of the following month (the "1940 Act Cure Date"),
the Fund will be required under certain circumstances to redeem certain of the
AMPS. See "Redemption" below.
 
                                      17

  The 1940 Act AMPS Asset Coverage immediately following the issuance of AMPS
offered hereby (after giving effect to the deduction of the sales load and
offering expenses for the AMPS) will be computed as follows:

AMPS Basic Maintenance Amount. The AMPS Basic Maintenance Amount includes the
sum of (i) the aggregate liquidation value of AMPS then outstanding and (ii)
certain accrued and projected payment obligations of the Fund. See
"Description of AMPS--Asset Maintenance--AMPS Basic Maintenance Amount" in the
statement of additional information. If the Fund fails to meet such
requirement as of any Valuation Date and such failure is not cured on or
before the sixth Business Day after such Valuation Date (the "AMPS Basic
Maintenance Cure Date"), the Fund will be required under certain circumstances
to redeem certain of the AMPS. Upon any failure to maintain the required
Discounted Value, the Fund will use its best efforts to alter the composition
of its portfolio to reattain a Discounted Value at least equal to the AMPS
Basic Maintenance Amount on or prior to the AMPS Basic Maintenance Cure Date.
See "Redemption" herein and in the statement of additional information.
 
REDEMPTION
 
  Optional Redemption. To the extent permitted under the 1940 Act and under
Maryland law, upon giving a Notice of Redemption, as provided in the statement
of additional information, the Fund, at its option, may redeem AMPS of any
series, in whole or in part, out of funds legally available therefor, at the
Optional Redemption Price per share on any Dividend Payment Date; provided
that no share of AMPS may be redeemed at the option of the Fund during (a) the
Initial Dividend Period with respect to a series of shares or (b) a Non-Call
Period to which such share is subject. "Optional Redemption Price" means
$25,000 per share of AMPS plus an amount equal to accumulated but unpaid
dividends (whether or not earned or declared) to the date fixed for redemption
plus any applicable redemption premium, if any, attributable to the
designation of a Premium Call Period. In addition, holders of AMPS may be
entitled to receive Additional Dividends in the event of redemption of such
AMPS to the extent provided herein. See "Dividends--Additional Dividends"
above. The Fund has the authority to redeem the AMPS for any reason and may
redeem all or part of the outstanding AMPS if it anticipates that the Fund's
leveraged capital structure will result in a lower rate of return to holders
of common shares for any significant period of time than that obtainable if
the common shares were unleveraged.
 
  Mandatory Redemption. The Fund will be required to redeem, out of funds
legally available therefor, at the Mandatory Redemption Price per share, AMPS
to the extent permitted under the 1940 Act and Maryland law, on a date fixed
by the Board of Trustees, if the Fund fails to maintain S&P Eligible Assets
and Moody's Eligible Assets each with an aggregate Discounted Value equal to
or greater than the AMPS Basic Maintenance Amount or to satisfy the 1940 Act
AMPS Asset Coverage and such failure is not cured on or before the AMPS Basic
Maintenance Cure Date or the 1940 Act Cure Date (herein collectively referred
to as a "Cure Date"), as the case may be. "Mandatory Redemption Price" means
$25,000 per share of AMPS plus an amount equal to accumulated but unpaid
dividends (whether or not earned or declared) to the date fixed for
redemption. In addition, holders of AMPS may be entitled to receive Additional
Dividends in the event of redemption of such AMPS to the extent provided
herein. See "Dividends--Additional Dividends" above.

  For a discussion of the allocation procedures to be used if fewer than all
of the outstanding AMPS of either series are to be redeemed and for a
discussion of other redemption procedures, see "Description of AMPS--
Redemption" in the statement of additional information.
 
LIQUIDATION RIGHTS
 
  Upon any liquidation, dissolution or winding up of the Fund, whether
voluntary or involuntary, the holders of all series of AMPS will be entitled
to receive, out of the assets of the Fund available for distribution to
shareholders, before any distribution or payment is made upon any common
shares or any other capital shares of the Fund ranking junior in right of
payment upon liquidation of AMPS, $25,000 per share together with the amount
of any dividends accumulated but unpaid (whether or not earned or declared)
thereon to the date of distribution, and after such payment the holders of
AMPS will be entitled to no other payments except for any Additional
Dividends. If such assets of the Fund shall be insufficient to make the full
liquidation payment on each outstanding series of AMPS and liquidation
payments on any other outstanding class or series of preferred shares of the
Fund ranking on a parity with the AMPS as to payment upon liquidation, then
such assets will be distributed among the holders of each such series of AMPS
and the holders of such other class or series ratably in proportion to the
respective preferential amounts to which they are entitled. After payment of
the full amount of liquidation distribution to which they are entitled, the
holders of AMPS will not be entitled to any further participation in any
distribution of assets by the Fund except for any Additional Dividends. A
consolidation, merger or share exchange of the Fund with or into any other
entity or entities or a sale, whether for cash, shares of stock, securities or
properties, of all or substantially all or any part of the assets of the Fund
shall not be deemed or construed to be a liquidation, dissolution or winding
up of the Fund.
 
VOTING RIGHTS
 
  Except as otherwise indicated in this prospectus and the statement of
additional information and except as otherwise required by applicable law,
holders of AMPS will be entitled to one vote per share on each matter
submitted to a vote of shareholders and will vote together with holders of
common shares as a single class.
 
  The 1940 Act and the Certificate of Designation require that the holders of
preferred shares, including the AMPS, voting as a separate class, have the
rights to elect two of the Fund's Trustees at all times and to elect a
majority of the Trustees at any time that two full years' dividends on the
AMPS are unpaid. The holders of AMPS will vote as a separate class or classes
on certain other matters as required under the Certificate of Designation, the
1940 Act and Maryland law. In addition, each series of AMPS may vote as a
separate series under certain circumstances. See "Description of AMPS--Voting
Rights" in the statement of additional information.
 
                                  THE AUCTION
 
GENERAL
 
  Holders of the AMPS of each series will be entitled to receive cumulative
cash dividends on their shares when, as and if declared by the Board of
Trustees of the Fund, out of funds legally available therefor, on the Initial
Dividend Payment Date with respect to the Initial Dividend Period and,
thereafter, on each Dividend Payment Date with respect to a Subsequent
Dividend Period (generally a period of seven days subject to certain
exceptions set forth under "Description of AMPS--Dividends--General") at the
rate per annum equal to the Applicable Rate for each such Dividend Period.
 
  The provisions of the Certificate of Designation establishing the terms of
the AMPS offered hereby will provide that the Applicable Rate for each series
of AMPS for each Dividend Period after the Initial Dividend Period therefor
will be equal to the rate per annum that the Auction Agent advises has
resulted on the Business Day preceding the first day of such Dividend Period
due to implementation of the auction procedures set forth in the Certificate
of Designation (the "Auction Procedures") in which persons determine to hold
or offer to purchase or sell AMPS of such series. The Auction Procedures are
attached as Appendix E to the statement of additional information.
 
                                      19
<PAGE>
 
  Each periodic operation of such procedures with respect to the AMPS is
referred to hereinafter as an "Auction." If, however, the Fund should fail to
pay or duly provide for the full amount of any dividend on AMPS of any series
or the redemption price of AMPS of such series called for redemption, the
Applicable Rate for AMPS will be determined as set forth under "Description of
AMPS--Dividends--Non-Payment Period; Late Charge" in the statement of
additional information.
 
  Auction Agent Agreement. The Fund will enter into an agreement (the "Auction
Agent Agreement") with IBJ Whitehall Bank & Trust Company (together with any
successor bank or trust company or other entity entering into a similar
agreement with this Fund, the "Auction Agent"), which provides, among other
things, that the Auction Agent will follow the Auction Procedures for the
purpose of determining the Applicable Rate for the AMPS. The Fund will pay the
Auction Agent compensation for its services under the Auction Agent Agreement.
 
  Broker-Dealer Agreements. The Auction Agent will enter into agreements with
Merrill Lynch, Goldman, Sachs & Co., Lehman Government Securities Incorporated
and Salomon Smith Barney Inc. and may enter into similar agreements
(collectively, the "Broker-Dealer Agreements") with one or more other broker-
dealers (collectively, the "Broker-Dealers") selected by the Fund, which
provide for the participation of such Broker-Dealers in Auctions. Merrill
Lynch is an affiliate of the Investment Adviser in that they share a common
parent, ML & Co.
 
  Securities Depository. The Depository Trust Company initially will act as
the Securities Depository for the Agent Members with respect to the AMPS of
each series. One or more registered certificates for all of the shares of each
series of AMPS initially will be registered in the name of Cede, as nominee of
the Securities Depository. The certificate will bear a legend to the effect
that such certificate is issued subject to the provisions restricting
transfers of AMPS of the series to which it relates contained in the
Certificate of Designation. Cede initially will be the holder of record of all
AMPS, and Beneficial Owners will not be entitled to receive certificates
representing their ownership interest in such shares. The Securities
Depository will maintain lists of its participants and will maintain the
positions (ownership interests) of AMPS held by each Agent Member, whether as
the Beneficial Owner thereof for its own account or as nominee for the
Beneficial Owner thereof. Payments made by the Fund to holders of AMPS will be
duly made by making payments to the nominee of the Securities Depository.
 
AUCTION PROCEDURES
 
  The following is a brief discussion of the procedures to be used in
conducting Auctions. Separate auctions will be conducted for each series of
AMPS. This summary is qualified by reference to the Auction Procedures set
forth in Appendix E to the statement of additional information. The Settlement
Procedures to be used with respect to Auctions are set forth in Appendix D to
the statement of additional information.
 
  Auction Date; Advance Notice of Allocation of Taxable Income; Inclusion of
Taxable Income in Dividends. An Auction to determine the Applicable Rate for
each series of AMPS offered hereby for each Dividend Period for such series
(other than the Initial Dividend Period therefor) will be held on the first
Business Day (as hereinafter defined) preceding the first day of such Dividend
Period, which first day is also the Dividend Payment Date for the preceding
Dividend Period (the date of each Auction being referred to herein as an
"Auction Date"). "Business Day" means a day on which the New York Stock
Exchange is open for trading and which is not a Saturday, Sunday or other day
on which banks in the City of New York are authorized or obligated by law to
close. Auctions for Series A AMPS for Dividend Periods after the Initial
Dividend Period normally will be held every     after the preceding Dividend
Payment Date, and each subsequent Dividend Period normally will begin on the
following     (also a Dividend Payment Date). Auctions for Series B AMPS for
Dividend Periods after the Initial Dividend Period normally will be held every
    after the
 
                                      20
<PAGE>
 
preceding Dividend Payment Date, and each subsequent Dividend Period normally
will begin on the following     (also a Dividend Payment Date). The Auction
Date and the first day of the related Dividend Period (both of which must be
Business Days) need not be consecutive calendar days. For example, in most
cases, if the     that normally would be an Auction Date for Series A AMPS is
not a Business Day, then such Auction Date will be the preceding     and the
first day of the related Dividend Period will continue to be the following
   . See "Description of AMPS--Dividends" for information concerning the
circumstances under which a Dividend Payment Date may fall on a date other
than the days specified above, which may affect the Auction Date.
 
  Except as noted below, whenever the Fund intends to include any net capital
gains or other income subject to regular Federal income taxes in any dividend
on AMPS, the Fund will notify the Auction Agent of the amount to be so
included at least five Business Days prior to the Auction Date on which the
Applicable Rate for such dividend is to be established. Whenever the Auction
Agent receives such notice from the Fund, in turn it will notify each Broker-
Dealer, who, on or prior to such Auction Date, in accordance with its Broker-
Dealer Agreement, will notify its customers who are Beneficial Owners and
Potential Beneficial Owners believed to be interested in submitting an Order
in the Auction to be held on such Auction Date. The Fund also may include such
income in a dividend on AMPS without giving advance notice thereof if it
increases the dividend by an additional amount calculated as if such income
were a Retroactive Taxable Allocation and the additional amount were an
Additional Dividend; provided that the Fund will notify the Auction Agent of
the additional amounts to be included in such dividend at least five Business
Days prior to the applicable Dividend Payment Date. See "Description of AMPS--
Dividends--Additional Dividends" above.
 
  Orders by Beneficial Owners, Potential Beneficial Owners, Existing Holders
and Potential Holders. On or prior to each Auction Date:
 
    (a) each Beneficial Owner may submit to its Broker-Dealer by telephone a:
 
      (i) Hold Order--indicating the number of outstanding AMPS, if any,
    that such Beneficial Owner desires to continue to hold without regard
    to the Applicable Rate for the next Dividend Period for such shares;
 
      (ii) Bid--indicating the number of outstanding AMPS, if any, that
    such Beneficial Owner desires to continue to hold, provided that the
    Applicable Rate for the next Dividend Period for such shares is not
    less than the rate per annum then specified by such Beneficial Owner;
    and/or
 
      (iii) Sell Order--indicating the number of outstanding AMPS, if any,
    that such Beneficial Owner offers to sell without regard to the
    Applicable Rate for the next Dividend Period for such shares; and
 
    (b) Broker-Dealers will contact customers who are Potential Beneficial
  Owners of AMPS to determine whether such Potential Beneficial Owners desire
  to submit Bids indicating the number of AMPS which they offer to purchase
  provided that the Applicable Rate for the next Dividend Period for such
  shares is not less than the rates per annum specified in such Bids.
 
  The communication by a Beneficial Owner or Potential Beneficial Owner to a
Broker-Dealer and the communication by a Broker-Dealer, whether or not acting
for its own account, to the Auction Agent of the foregoing information is
hereinafter referred to as an "Order" and collectively as "Orders." A
Beneficial Owner or a Potential Beneficial Owner placing an Order, including a
Broker-Dealer acting in such capacity for its own account, is hereinafter
referred to as a "Bidder" and collectively as "Bidders." Any Order submitted
by a Beneficial Owner or a Potential Beneficial Owner to its Broker-Dealer, or
by a Broker-Dealer to the Auction Agent, prior to the Submission Deadline on
any Auction Date shall be irrevocable.
 
  In an Auction, a Beneficial Owner may submit different types of Orders with
respect to AMPS then held by such Beneficial Owner, as well as Bids for
additional AMPS. For information concerning the priority given to different
types of Orders placed by Beneficial Owners, see "Submission of Orders by
Broker-Dealers to Auction Agent" below.
 
                                      21
<PAGE>
 
  The Maximum Applicable Rate for AMPS will be the Applicable Percentage of
the Reference Rate. The Auction Agent will round each applicable Maximum
Applicable Rate to the nearest one-thousandth (0.001) of one percent per
annum, with any such number ending in five ten-thousandths of one percent
being rounded upwards to the nearest one-thousandth (0.001) of one percent.
The Auction Agent will not round the applicable Reference Rate as part of its
calculation of the Maximum Applicable Rate.
 
  The Maximum Applicable Rate for AMPS will depend on the credit rating or
ratings assigned to such shares. The Applicable Percentage will be determined
based on (i) the lower of the credit rating or ratings assigned on such date
to such shares by Moody's and S&P (or if Moody's or S&P or both shall not make
such rating available, the equivalent of either or both of such ratings by a
Substitute Rating Agency or two Substitute Rating Agencies or, in the event
that only one such rating shall be available, such rating) and (ii) whether
the Fund has provided notification to the Auction Agent prior to the Auction
establishing the Applicable Rate for any dividend that net capital gains or
other taxable income will be included in such dividend on shares of AMPS as
follows:

</TABLE>
 
  There is no minimum Applicable Rate in respect of any Dividend Period.
 
  The Fund will take all reasonable action necessary to enable S&P and Moody's
to provide a rating for the AMPS. If either S&P or Moody's, or both, shall not
make such a rating available, the Underwriter or its affiliates and
successors, after consultation with the Fund, will select another nationally
recognized statistical rating organization (a "Substitute Rating Agency") or
two other nationally recognized statistical rating organizations ("Substitute
Rating Agencies") to act as a Substitute Rating Agency or Substitute Rating
Agencies, as the case may be.
 
  Any Bid by a Beneficial Owner specifying a rate per annum higher than the
Maximum Applicable Rate will be treated as a Sell Order, and any Bid by a
Potential Beneficial Owner specifying a rate per annum higher than the Maximum
Applicable Rate will not be considered. See "Determination of Sufficient
Clearing Bids, Winning Bid Rate and Applicable Rate" and "Acceptance and
Rejection of Submitted Bids and Submitted Sell Orders and Allocation of
Shares."
 
  Neither the Fund nor the Auction Agent will be responsible for a Broker-
Dealer's failure to comply with the foregoing.
 
  A Broker-Dealer also may hold AMPS in its own account as a Beneficial Owner.
A Broker-Dealer thus may submit Orders to the Auction Agent as a Beneficial
Owner or a Potential Beneficial Owner and therefore participate in an Auction
as an Existing Holder or Potential Holder on behalf of both itself and its
customers. Any Order placed with the Auction Agent by a Broker-Dealer as or on
behalf of a Beneficial Owner or a Potential Beneficial Owner will be treated
in the same manner as an Order placed with a Broker-Dealer by a Beneficial
Owner or a Potential Beneficial Owner. Similarly, any failure by a Broker-
Dealer to submit to the Auction Agent an Order in respect of any AMPS held by
it or its customers who are Beneficial Owners will be treated in the same
manner as a Beneficial Owner's failure to submit to its Broker-Dealer an Order
in respect of AMPS held by it, as described in the next paragraph. Inasmuch as
a Broker-Dealer participates in an Auction as an Existing Holder or a
Potential Holder only to represent the interests of a Beneficial Owner or
Potential Beneficial Owner, whether it be its customers or itself, all
discussion herein relating to the consequences of an Auction for Existing
Holders and Potential Holders also applies to the underlying beneficial
ownership interests
 
                                      22
<PAGE>
 
represented thereby. For information concerning the priority given to
different types of Orders placed by Existing Holders, see "Submission of
Orders by Broker-Dealers to Auction Agent." Each purchase or sale in an
Auction will be settled on the Business Day next succeeding the Auction Date
at a price per share equal to $25,000. See "Notification of Results;
Settlement" below.
 
  If one or more Orders covering in the aggregate all of the outstanding AMPS
held by a Beneficial Owner are not submitted to the Auction Agent prior to the
Submission Deadline, either because a Broker-Dealer failed to contact such
Beneficial Owner or otherwise, the Auction Agent shall deem a Hold Order (in
the case of an Auction relating to a Dividend Period which is not a Special
Dividend Period of 28 days or more) and a Sell Order (in the case of an
Auction relating to a Special Dividend Period of 28 days or more) to have been
submitted on behalf of such Beneficial Owner covering the number of
outstanding AMPS held by such Beneficial Owner and not subject to Orders
submitted to the Auction Agent.
 
  If all of the outstanding AMPS are subject to Submitted Hold Orders, the
Dividend Period next succeeding the Auction automatically shall be the same
length as the immediately preceding Dividend Period, and the Applicable Rate
for the next Dividend Period for all AMPS will be 40% of the Reference Rate on
the date of the applicable Auction (or 60% of such rate if the Fund has
provided notification to the Auction Agent prior to the Auction establishing
the Applicable Rate for any dividend that net capital gains or other taxable
income will be included in such dividend on AMPS).
 
  For the purposes of an Auction, AMPS for which the Fund shall have given
notice of redemption and deposited moneys therefor with the Auction Agent in
trust or segregated in an account at the Fund's custodian bank for the benefit
of the Auction Agent, as set forth under "Description of AMPS--Redemption" in
the statement of additional information, will not be considered as outstanding
and will not be included in such Auction. Pursuant to the Certificate of
Designation of the Fund, the Fund will be prohibited from reissuing and its
affiliates (other than the Underwriter) will be prohibited from transferring
(other than to the Fund) any shares of AMPS they may acquire. Neither the Fund
nor any affiliate of the Fund (other than the Underwriter) may submit an Order
in any Auction, except that an affiliate of the Fund that is a Broker-Dealer
may submit an Order.
 
  Submission of Orders by Broker-Dealers to Auction Agent. Prior to 1:00 p.m.,
Eastern time, on each Auction Date, or such other time on the Auction Date as
may be specified by the Auction Agent (the "Submission Deadline"), each
Broker-Dealer will submit to the Auction Agent in writing all Orders obtained
by it for the Auction to be conducted on such Auction Date, designating itself
(unless otherwise permitted by the Fund) as the Existing Holder or Potential
Holder in respect of the AMPS subject to such Orders. Any Order submitted by a
Beneficial Owner or a Potential Beneficial Owner to its Broker-Dealer, or by a
Broker-Dealer to the Auction Agent, prior to the Submission Deadline on any
Auction Date, shall be irrevocable.
 
  If the rate per annum specified in any Bid contains more than three figures
to the right of the decimal point, the Auction Agent will round such rate per
annum up to the next highest one-thousandth (.001) of 1%.
 
  If one or more Orders of an Existing Holder are submitted to the Auction
Agent and such Orders cover in the aggregate more than the number of
outstanding AMPS held by such Existing Holder, such Orders will be considered
valid in the following order of priority:
 
    (i) any Hold Order will be considered valid up to and including the
  number of outstanding AMPS held by such Existing Holder, provided that if
  more than one Hold Order is submitted by such Existing Holder and the
  number of AMPS subject to such Hold Orders exceeds the number of
  outstanding AMPS held by such Existing Holder, the number of AMPS subject
  to each of such Hold Orders will be reduced pro rata so that such Hold
  Orders, in the aggregate, will cover exactly the number of outstanding AMPS
  held by such Existing Holder;
 
    (ii) any Bids will be considered valid, in the ascending order of their
  respective rates per annum if more than one Bid is submitted by such
  Existing Holder, up to and including the excess of the number of
  outstanding AMPS held by such Existing Holder over the number of
  outstanding AMPS subject to any Hold
 
                                      23
<PAGE>
 
  Order referred to in clause (i) above (and if more than one Bid submitted
  by such Existing Holder specifies the same rate per annum and together they
  cover more than the remaining number of shares that can be the subject of
  valid Bids after application of clause (i) above and of the foregoing
  portion of this clause (ii) to any Bid or Bids specifying a lower rate or
  rates per annum, the number of shares subject to each of such Bids will be
  reduced pro rata so that such Bids, in the aggregate, cover exactly such
  remaining number of outstanding shares); and the number of outstanding
  shares, if any, subject to Bids not valid under this clause (ii) shall be
  treated as the subject of a Bid by a Potential Holder; and
 
    (iii) any Sell Order will be considered valid up to and including the
  excess of the number of outstanding AMPS held by such Existing Holder over
  the sum of the number of shares of AMPS subject to Hold Orders referred to
  in clause (i) above and the number of AMPS subject to valid Bids by such
  Existing Holder referred to in clause (ii) above; provided that, if more
  than one Sell Order is submitted by any Existing Holder and the number of
  AMPS subject to such Sell Orders is greater than such excess, the number of
  AMPS subject to each of such Sell Orders will be reduced pro rata so that
  such Sell Orders, in the aggregate, will cover exactly the number of AMPS
  equal to such excess.
 
  If more than one Bid of any Potential Holder is submitted in any Auction,
each Bid submitted in such Auction will be considered a separate Bid with the
rate per annum and number of AMPS therein specified.
 
  Determination of Sufficient Clearing Bids, Winning Bid Rate and Applicable
Rate. Not earlier than the Submission Deadline for each Auction, the Auction
Agent will assemble all Orders submitted or deemed submitted to it by the
Broker-Dealers (each such "Hold Order," "Bid" or "Sell Order" as submitted or
deemed submitted by a Broker-Dealer hereinafter being referred to as a
"Submitted Hold Order," a "Submitted Bid" or a "Submitted Sell Order," as the
case may be, or as a "Submitted Order") and will determine the excess of the
number of outstanding shares of AMPS over the number of outstanding AMPS
subject to Submitted Hold Orders (such excess being referred to as the
"Available AMPS") and whether Sufficient Clearing Bids have been made in such
Auction. Sufficient Clearing Bids will have been made if the number of
outstanding AMPS that are the subject of Submitted Bids of Potential Holders
with rates per annum not higher than the Maximum Applicable Rate equals or
exceeds the number of outstanding shares that are the subject of Submitted
Sell Orders (including the number of shares subject to Bids of Existing
Holders specifying rates per annum higher than the Maximum Applicable Rate).
 
  If Sufficient Clearing Bids have been made, the Auction Agent will determine
the lowest rate per annum specified in the Submitted Bids (the "Winning Bid
Rate") which would result in the number of shares subject to Submitted Bids
specifying such rate per annum or a lower rate per annum being at least equal
to the Available AMPS. If Sufficient Clearing Bids have been made, the Winning
Bid Rate will be the Applicable Rate for the next Dividend Period for all AMPS
then outstanding.
 
  If Sufficient Clearing Bids have not been made (other than because all
outstanding shares of AMPS are the subject of Submitted Hold Orders), the
Dividend Period next following the Auction automatically will be a 7-Day
Dividend Period, and the Applicable Rate for such Dividend Period will be
equal to the Maximum Applicable Rate. If Sufficient Clearing Bids have not
been made, Beneficial Owners that have Submitted Sell Orders will not be able
to sell in the Auction all, and may not be able to sell any, AMPS subject to
such Submitted Sell Orders. See "Acceptance and Rejection of Submitted Bids
and Submitted Sell Orders and Allocation of Shares." Thus, under some
circumstances, Beneficial Owners may not have liquidity of investment.
 
  Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and
Allocation of Shares. Based on the determinations described under
"Determination of Sufficient Clearing Bids, Winning Bid Rate and Applicable
Rate" and subject to the discretion of the Auction Agent to round as described
below, Submitted Bids and Submitted Sell Orders will be accepted or rejected
in the order of priority set forth in the Auction Procedures with the result
that Existing Holders and Potential Holders of AMPS will sell, continue to
hold and/or
 
                                      24
<PAGE>
 
purchase AMPS as set forth below. Existing Holders that submit or are deemed
to have submitted Hold Orders will continue to hold the AMPS subject to such
Hold Orders.
 
  If Sufficient Clearing Bids have been made:
 
    (a) each Existing Holder that placed a Submitted Bid specifying a rate
  per annum higher than the Winning Bid Rate or a Submitted Sell Order will
  sell the outstanding AMPS subject to such Submitted Bid or Submitted Sell
  Order;
 
    (b) each Existing Holder that placed a Submitted Bid specifying a rate
  per annum lower than the Winning Bid Rate will continue to hold the
  outstanding AMPS subject to such Submitted Bid;
 
    (c) each Potential Holder that placed a Submitted Bid specifying a rate
  per annum lower than the Winning Bid Rate will purchase the number of AMPS
  subject to such Submitted Bid;
 
    (d) each Existing Holder that placed a Submitted Bid specifying a rate
  per annum equal to the Winning Bid Rate will continue to hold the
  outstanding AMPS subject to such Submitted Bids, unless the number of
  outstanding AMPS subject to all such Submitted Bids of Existing Holders is
  greater than the excess of the Available AMPS over the number of AMPS
  accounted for in clauses (b) and (c) above, in which event each Existing
  Holder with such a Submitted Bid will sell a number of outstanding AMPS
  determined on a pro rata basis based on the number of outstanding AMPS
  subject to all such Submitted Bids of such Existing Holders; and
 
    (e) each Potential Holder that placed a Submitted Bid specifying a rate
  per annum equal to the Winning Bid Rate will purchase any Available AMPS
  not accounted for in clause (b), (c) or (d) above on a pro rata basis based
  on the AMPS subject to all such Submitted Bids of Potential Holders.
 
  If Sufficient Clearing Bids have not been made (other than because all
outstanding shares of AMPS are the subject of Submitted Hold Orders):
 
    (a) each Existing Holder that placed a Submitted Bid specifying a rate
  per annum equal to or lower than the Maximum Applicable Rate will continue
  to hold the outstanding AMPS subject to such Submitted Bid;
 
    (b) each Potential Holder that placed a Submitted Bid specifying a rate
  per annum equal to or lower than the Maximum Applicable Rate will purchase
  the number of AMPS subject to such Submitted Bid; and
 
    (c) each Existing Holder that placed a Submitted Bid specifying a rate
  per annum higher than the Maximum Applicable Rate or a Submitted Sell Order
  will sell a number of outstanding AMPS determined on a pro rata basis based
  on the outstanding AMPS subject to all such Submitted Bids and Submitted
  Sell Orders.
 
  If as a result of the Auction Procedures described above any Existing Holder
would be entitled or required to sell, or any Potential Holder would be
entitled or required to purchase, a fraction of a share of AMPS, the Auction
Agent, in such manner as, in its sole discretion, it shall determine, will
round up or down the number of AMPS being sold or purchased on such Auction
Date so that each share sold or purchased by each Existing Holder or Potential
Holder will be a whole share of AMPS. If any Potential Holder would be
entitled or required to purchase less than a whole share of AMPS, the Auction
Agent, in such manner as, in its sole discretion, it shall determine, will
allocate AMPS for purchase among Potential Holders so that only whole shares
of AMPS are purchased by any such Potential Holder, even if such allocation
results in one or more of such Potential Holders not purchasing any AMPS.
 
  Notification of Results; Settlement. The Auction Agent will advise each
Broker-Dealer who submitted a Bid or Sell Order in an Auction whether such Bid
or Sell Order was accepted or rejected in whole or in part and of the
Applicable Rate for the next Dividend Period for the related AMPS by telephone
at approximately 3:00 P.M., Eastern time, on the Auction Date for such
Auction. Each such Broker-Dealer that submitted an Order for the account of a
customer then will advise such customer whether such Bid or Sell Order was
accepted or rejected, will confirm purchases and sales with each customer
purchasing or selling AMPS as a result of the
 
                                      25
<PAGE>
 
Auction and will advise each customer purchasing or selling AMPS to give
instructions to its Agent Member of the Securities Depository to pay the
purchase price against delivery of such shares or to deliver such shares
against payment therefor as appropriate. If a customer selling AMPS as a
result of an Auction shall fail to instruct its Agent Member to deliver such
shares, the Broker-Dealer that submitted such customer's Bid or Sell Order
will instruct such Agent Member to deliver such shares against payment
therefor. Each Broker-Dealer that submitted a Hold Order in an Auction on
behalf of a customer also will advise such customer of the Applicable Rate for
the next Dividend Period for the AMPS. The Auction Agent will record each
transfer of AMPS on the record book of Existing Holders to be maintained by
the Auction Agent.
 
  In accordance with the Securities Depository's normal procedures, on the day
after each Auction Date, the transactions described above will be executed
through the Securities Depository, and the accounts of the respective Agent
Members at the Securities Depository will be debited and credited as necessary
to effect the purchases and sales of AMPS as determined in such Auction.
Purchasers will make payment through their Agent Members in same-day funds to
the Securities Depository against delivery through their Agent Members; the
Securities Depository will make payment in accordance with its normal
procedures, which now provide for payment in same-day funds. If the procedures
of the Securities Depository applicable to AMPS shall be changed to provide
for payment in next-day funds, then purchasers may be required to make payment
in next-day funds. If the certificates for AMPS are not held by the Securities
Depository or its nominee, payment will be made in same-day funds to the
Auction Agent against delivery of such certificates.
 
  If any Existing Holder selling AMPS in an Auction fails to deliver such
shares, the Broker-Dealer of any person that was to have purchased AMPS in
such Auction may deliver to such person a number of whole AMPS that is less
than the number of shares that otherwise was to be purchased by such person.
In such event, the number of AMPS to be so delivered will be determined by
such Broker-Dealer. Delivery of such lesser number of shares will constitute
good delivery. Each Broker-Dealer Agreement also will provide that neither the
Fund nor the Auction Agent will have responsibility or liability with respect
to the failure of a Potential Beneficial Owner, Beneficial Owner or their
respective Agent Members to deliver AMPS or to pay for AMPS purchased or sold
pursuant to an Auction or otherwise.
 
BROKER-DEALERS
 
  General. The Broker-Dealer Agreements provide that a Broker-Dealer may
submit Orders in Auctions for its own account, unless the Fund notifies all
Broker-Dealers that they no longer may do so; provided that Broker-Dealers may
continue to submit Hold Orders and Sell Orders. If a Broker-Dealer submits an
Order for its own account in any Auction of any series of AMPS, it may have
knowledge of Orders placed through it in that Auction and therefore have an
advantage over other Bidders, but such Broker-Dealer would not have knowledge
of Orders submitted by other Broker-Dealers in that Auction.
 
  Fees. The Auction Agent after each Auction will pay a service charge from
funds provided by the Fund to each Broker-Dealer on the basis of the purchase
price of AMPS placed by such Broker-Dealer at such Auction. The service charge
(i) for any 7-Day Dividend Period shall be payable at the annual rate of 0.25%
of the purchase price of the AMPS placed by such Broker-Dealer in any such
Auction and (ii) for any Special Dividend Period shall be determined by mutual
consent of the Fund and any such Broker-Dealer or Broker-Dealers and shall be
based upon a selling concession that would be applicable to an underwriting of
fixed or variable rate preferred shares with a similar final maturity or
variable rate dividend period, respectively, at the commencement of the
Dividend Period with respect to such Auction. For the purposes of the
preceding sentence, AMPS will be placed by a Broker-Dealer if such shares were
(i) the subject of Hold Orders deemed to have been made by Beneficial Owners
that were acquired by such Beneficial Owners through such Broker-Dealer or
(ii) the subject of the following Orders submitted by such Broker-Dealer: (A)
a Submitted Bid of a Beneficial Owner that resulted in such Beneficial Owner
continuing to hold such shares as a result of the Auction, (B) a Submitted Bid
of a Potential Beneficial Owner that resulted in such Potential Beneficial
Owner purchasing such shares as a result of the Auction or (C) a Submitted
Hold Order.

  Secondary Trading Market. The Broker-Dealers intend to maintain a secondary
trading market in the AMPS outside of Auctions; however, they have no
obligation to do so and there can be no assurance that a secondary market for
the AMPS will develop or, if it does develop, that it will provide holders
with a liquid trading market (i.e., trading will depend on the presence of
willing buyers and sellers and the trading price is subject to variables to be
determined at the time of the trade by the Broker-Dealers). The AMPS will not
be registered on any stock exchange or on any automated quotation system. An
increase in the level of interest rates, particularly during any Long-Term
Dividend Period, likely will have an adverse effect on the secondary market
price of the AMPS, and a selling shareholder may sell AMPS between Auctions at
a price per share of less than $25,000.
 
                           RATING AGENCY GUIDELINES
 
  Certain of the capitalized terms used herein are defined in the Glossary
that appears at the end of this prospectus.
 
  The Fund intends that, so long as AMPS are outstanding, the composition of
its portfolio will reflect guidelines established by Moody's and S&P in
connection with the Fund's receipt of a rating for such shares on or prior to
their Date of Original Issue of at least "aaa" from Moody's and AAA from S&P.
Moody's and S&P, which are NRSROs, issue ratings for various securities
reflecting the perceived creditworthiness of such securities. The guidelines
described below have been developed by Moody's and S&P in connection with
issuances of asset-backed and similar securities, including debt obligations
and variable rate preferred stock, generally on a case-by-case basis through
discussions with the issuers of these securities. The guidelines are designed
to ensure that assets underlying outstanding debt or preferred stock will be
varied sufficiently and will be of sufficient quality and amount to justify
investment-grade ratings. The guidelines do not have the force of law but have
been adopted by the Fund in order to satisfy current requirements necessary
for Moody's and S&P to issue the above-described ratings for AMPS, which
ratings generally are relied upon by institutional investors in purchasing
such securities. The guidelines provide a set of tests for portfolio
composition and asset coverage that supplement (and in some cases are more
restrictive than) the applicable requirements under the 1940 Act. See
"Description of AMPS--Asset Maintenance" herein and in the statement of
additional information.
 
  The Fund intends to maintain a Discounted Value for its portfolio at least
equal to the AMPS Basic Maintenance Amount. Moody's and S&P each has
established separate guidelines for determining Discounted Value. To the
extent any particular portfolio holding does not satisfy the applicable rating
agency's guidelines, all or a portion of such holding's value will not be
included in the calculation of Discounted Value (as defined by such rating
agency). The Moody's and S&P guidelines do not impose any limitations on the
percentage of Fund assets that may be invested in holdings not eligible for
inclusion in the calculation of the Discounted Value of the Fund's portfolio.
 
  Upon any failure to maintain the required Discounted Value, the Fund will
seek to alter the composition of its portfolio to reattain a Discounted Value
at least equal to the AMPS Basic Maintenance Amount on or prior to the AMPS
Basic Maintenance Cure Date, thereby incurring additional transaction costs
and possible losses and/or gains on dispositions of portfolio securities. To
the extent any such failure is not cured in a timely manner, AMPS will be
subject to redemption. See "Description of AMPS--Asset Maintenance" and
"Description of AMPS--Redemption" herein and in the statement of additional
information.
 
  The Fund may, but is not required to, adopt any modifications to these
guidelines that hereafter may be established by Moody's or S&P. Failure to
adopt any such modifications, however, may result in a change in the ratings
described above or a withdrawal of ratings altogether. In addition, any rating
agency providing a rating for the AMPS, at any time, may change or withdraw
any such rating. As set forth in the Certificate of Designation, the Board of
Trustees, without shareholder approval, may modify certain definitions or
restrictions that have been adopted by the Fund pursuant to the rating agency
guidelines, provided the Board of Trustees has obtained written confirmation
from Moody's and S&P that any such change would not impair the ratings then
assigned by Moody's and S&P to the AMPS.
 
 
                                      27
<PAGE>
 
  As described by Moody's and S&P, a preferred stock rating is an assessment
of the capacity and willingness of an issuer to pay preferred stock
obligations. The ratings on the AMPS are not recommendations to purchase, hold
or sell AMPS, inasmuch as the ratings do not comment as to market price or
suitability for a particular investor, nor do the rating agency guidelines
described above address the likelihood that a holder of AMPS will be able to
sell such shares in an Auction. The ratings are based on current information
furnished to Moody's and S&P by the Fund and the Investment Adviser and
information obtained from other sources. The ratings may be changed, suspended
or withdrawn as a result of changes in, or the unavailability of, such
information. The Common Shares have not been rated by a nationally recognized
statistical rating organization.
 
  For additional information concerning the Moody's and S&P ratings
guidelines, see "Rating Agency Guidelines" in the statement of additional
information.
 
                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 other registered investment companies and
offers investment advisory services to individuals and institutional accounts.
As of      1998, the Merrill Lynch Asset Management Group had a total of
approximately $   billion in investment company and other portfolio assets
under management (approximately $   billion of which were 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. 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 supervision
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. Robert D. Sneeden, Jr.
and Robert A. DiMella 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 0.55
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,
 
                                      28
<PAGE>
 
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-interested 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.
 
                                     TAXES
 
  In general, dividends on the AMPS will be exempt from Federal income tax in
the hands of holders of such AMPS, subject to the possible application of the
Federal alternative minimum tax. However, the Fund is required to allocate net
capital gains and other taxable income, if any, proportionately among the
common shares and each series of AMPS in accordance with the current position
of the Internal Revenue Service ("IRS") described under the heading "Taxes" in
the statement of additional information. The Fund may notify the Auction Agent
of the amount of any net capital gains or other anticipated taxable income to
be included in any dividend on the AMPS prior to the Auction establishing the
Applicable Dividend Rate for such dividend. The Auction Agent will in turn
notify holders of the AMPS and prospective purchasers. The amount of taxable
income allocable to each series of AMPS will depend upon the amount of such
income realized by the Fund and cannot be determined with certainty prior to
the end of the Fund's fiscal year, but it is not generally expected to be
significant.
 
  In general, shares of the Fund will be exempt from Florida intangible
personal property tax for Florida resident shareholders. Dividends paid to
individual Florida residents are not subject to personal income taxation by
Florida, because Florida does not impose a personal income tax. 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.
 
  Generally, within 60 days after the end of the Fund's taxable year, the Fund
will tell you the amount of exempt-interest dividends, ordinary income
dividends or capital gain dividends you received that year. Capital gain
dividends are taxable as long-term capital gains to you regardless of how long
you have held your shares. The tax treatment of distributions from the Fund is
the same whether you choose to receive distributions in cash or to have them
reinvested in shares of the Fund.
 
  If the Fund makes a Retroactive Taxable Allocation, it will pay Additional
Dividends to holders of AMPS who are subject to the Retroactive Taxable
Allocation. See "Description of AMPS--Dividends--Additional Dividends." The
Federal income tax consequences of Additional Dividends under existing law are
uncertain. The Fund intends to treat a holder as receiving a dividend
distribution in the amount of any Additional Dividend only as and when such
Additional Dividend is paid. An Additional Dividend generally will be
designated by the Fund as an exempt-interest dividend except as otherwise
required by applicable law. However, the IRS may assert that all or part of an
Additional Dividend is a taxable dividend either in the taxable year for which
the Retroactive Taxable Allocation is made or in the taxable year in which the
Additional Dividend is paid.
 
  Because the Fund may from time to time invest a substantial portion of its
portfolio in municipal securities bearing income that is taxable under the
Federal alternative minimum tax, the Fund would not ordinarily be a suitable
investment for investors who are subject to the alternative minimum tax.
 
  If at any time when AMPS are outstanding the Fund does not meet the asset
coverage requirements of the 1940 Act, the Fund will be required to suspend
distributions to holders of Common Shares until the asset coverage is
restored. See "Description of AMPS--Restrictions on Dividends and Other
Payments." This may prevent the Fund from meeting certain distribution
requirements for qualification as a regulated investment company ("RIC"). Upon
any failure to meet the asset coverage requirements of the 1940 Act, the Fund,
in its sole discretion, may, and under certain circumstances will be required
to, redeem AMPS in order to maintain or
 
                                      29
<PAGE>
 
restore the requisite asset coverage and avoid the adverse consequences to the
Fund and its shareholders of failing to qualify as a RIC. See "Description of
AMPS--Redemption." There can be no assurance, however, that any such action
would achieve such objectives.
 
  By law, the Fund must withhold 31% of your distributions and proceeds if you
have not provided a taxpayer identification number or social security number.
For more information regarding the tax treatment of an investment in AMPS, see
"Taxes" in the statement of additional information.
 
  Shareholders are urged to consult their tax advisers regarding the
availability of any exemptions from state or local taxes and with specific
questions as to Federal, foreign, state or local taxes.
 
                         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. In connection with the offering
described herein, the Trustees of the Fund have authorized the issuance of
AMPS. For a description of the AMPS, see "Description of AMPS" herein and in
the statement of additional information.
 
  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 or 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.
 
  The following table shows the amount of (i) capital shares authorized, (ii)
capital shares held by the Fund for its own account and (iii) capital shares
outstanding for each class of authorized securities of the Fund as of        ,
1999.

COMMON SHARES
 
  Holders of common shares are entitled to share equally in dividends declared
by the Board of Trustees payable to holders of common shares and in the net
assets of the Fund available for distribution to holders of common shares
after payment of the preferential amounts payable to holders of any
outstanding preferred shares. Neither holders of common shares nor holders of
preferred shares have pre-emptive or conversion rights and shares of common
shares are not redeemable. The outstanding shares of common shares are fully
paid and non-assessable.
 
  Holders of common shares are entitled to one vote for each share held and
will vote with the holders of any outstanding AMPS or other preferred shares
on each matter submitted to a vote of holders of common shares, except as
described under "Description of AMPS--Voting Rights" herein and in the
statement of additional information.
 
  Shareholders are entitled to one vote for each share held. The common
shares, AMPS and any other preferred shares do not have cumulative voting
rights, which means that the holders of more than 50% of the common shares,
AMPS and any other preferred shares voting for the election of Trustees can
elect all of the Trustees standing for election by such holders, and, in such
event, the holders of the remaining common shares, AMPS and any other
preferred shares will not be able to elect any of such Trustees.
 
  So long as any AMPS or any other preferred shares are outstanding, holders
of common shares will not be entitled to receive any dividends of or other
distributions from the Fund unless all accumulated dividends on outstanding
AMPS and any other preferred shares have been paid, and unless asset coverage
(as defined in the 1940 Act) with respect to such AMPS and any other preferred
shares would be at least 200% after giving effect to such distributions. See
"Description of AMPS--Restrictions on Dividends and Other Payments" herein and
in the statement of additional information.
 
  The Fund will send unaudited reports at least semi-annually and audited
financial statements annually to all of its shareholders.
 
  The common shares commenced trading on the NYSE on       , 1999. At       ,
1999, the net asset value per common share was $  , and the closing price per
common share on the NYSE was $  .
 
PREFERRED SHARES
 
  Under the Certificate of Designation, the Fund is authorized to issue an
aggregate of     AMPS. See "Description of AMPS." Under the 1940 Act, the Fund
is permitted to have outstanding more than one series of preferred shares as
long as no single series has priority over another series as to the
distribution of assets of the Fund or the payment of dividends. Neither
holders of common shares nor holders of preferred shares have pre-emptive
rights to purchase any AMPS or any other preferred shares that might be
issued. It is anticipated that the net asset value per share of the AMPS will
equal its original purchase price per share plus accumulated dividends per
share.
 
CERTAIN PROVISIONS OF THE 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 of the holders of capital shares may be removed only by action of such
holders, and a Trustee elected by the holders of AMPS and any other preferred
shares may be removed only by action of AMPS and any other preferred shares.
 
                                      31
<PAGE>
 
  In addition, the Declaration of Trust requires the favorable vote of the
holders of at least 66 2/3% of the Fund's outstanding 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
    any other corporation,
 
  . 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 at least 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 all of the votes entitled to be cast by shareholders of the Fund, voting as
a single class, is required. Such approval, adoption or authorization of the
foregoing would also require the favorable vote of at least a majority of the
Fund's preferred shares then entitled to be voted, including the AMPS, 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 least 66 2/3% of the Fund's outstanding capital shares
(including the AMPS and any other 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 at least two-
thirds of the total number of Trustees fixed in accordance with the by-laws),
and, the affirmative vote of at least a majority of outstanding preferred
shares of the Fund (including the AMPS), voting as a separate class. Such a
vote also would satisfy a separate requirement in the 1940 Act that the change
be approved by the 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. Conversion
to an open-end investment company would also require redemption of all
outstanding preferred shares (including the AMPS) and would require changes in
certain of the Fund's investment policies and restrictions, such as those
relating to the issuance of senior securities, the borrowing of money and the
purchase of illiquid securities.
 
  The 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 Commission

                               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"). 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 before
January 1, 2000. The Investment Adviser expects to have addressed this problem
before then, and does not anticipate that the services it provides will be
adversely affected. The Fund's other service providers have told the
Investment Adviser that they also expect to resolve the Year 2000 Problem, and
the Investment Adviser will continue to monitor the situation as the Year 2000
approaches. However, if the problem has not been fully addressed, the Fund
could be negatively affected. The Year 2000 Problem could also have a negative
impact on the issuers of securities in which the Fund invests, and this could
hurt the Fund's investment returns.

  MuniHoldings Florida Insured Fund IV (the "Fund") is a recently 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 whose value 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 enables 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. There can be no assurance that the Fund's investment objective
will be realized. For more information on the Fund's investment objective and
policies, 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 whose
value is exempt from Florida intangible personal property tax. The Fund seeks
to achieve its investment 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 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 ("Florida Municipal Bonds"). The Fund intends to invest
substantially all (at least 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 that are exempt from
Federal income taxes but whose value 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,
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 options and futures
transactions 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 the 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.
 
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
("IDBs") are issued by or on behalf of public authorities to finance various
privately operated facilities, including certain local facilities for water
supply, gas, electricity, sewage or solid waste disposal. For purposes of this
statement of additional information, such obligations are considered Municipal
Bonds if the interest paid thereon is exempt from Federal income tax and as
Florida Municipal Bonds if the interest thereon is exempt from Federal income
tax and the obligations are exempt from Florida intangible personal property
tax, even though such bonds may be IDBs or "private activity bonds" as
discussed below. Also, for purposes of this statement of additional
information, Non-Municipal Tax-Exempt securities as discussed above will be
considered Florida Municipal Bonds or Municipal Bonds.
 
 
                                       3
<PAGE>
 
  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 (other than those of the State of
Florida, which has limited taxing powers) 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.
 
OPTIONS AND FUTURES TRANSACTIONS
 
  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.
 
 
                                       4
<PAGE>
 
  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.
 
  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 hedging 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 financial 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 financial futures contracts.
 
  The purchase or sale of a financial 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 which 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.
 
 
                                       5
<PAGE>
 
  Over-The-Counter Options.  The Fund may engage in options and futures
transactions on exchanges and in the over-the-counter markets. 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. Over-the-counter options
transactions ("OTC options") 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 which have a disparate impact on
the respective markets for such securities.
 
  Under regulations of the Commodity Futures Trading Commission (the "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.
 
 
                                       6
<PAGE>
 
  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.
 
  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 reached or exceeded 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 engaging in hedging transactions
when movements in interest rates occur. The Fund is not required to enter into
hedging transactions and may not do so.
 
                            INVESTMENT RESTRICTIONS
 
  The following are fundamental investment restrictions of the Fund and may
not be changed without the approval of the holders of a majority of the Fund's
outstanding common shares and outstanding AMPS and any other preferred shares,
voting as a single class, and the majority of the outstanding AMPS and any
other preferred shares, voting as a separate class (which for this purpose and
under the 1940 Act means the lesser of (i) 67% of the shares of each class of
capital shares represented at a meeting at which more than 50% of the
outstanding shares of each class of capital shares are represented or (ii)
more than 50% of the outstanding shares of each class of capital shares). 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 is investment objective, policies
  and limitations.
 
    6. Invest more than 25% of its total assets (taken at market value at the
  time of each investment) in securities of issuers in a single industry;
  provided that, for purposes of this restriction, states, municipalities and
  their political subdivisions are not considered to be part of any industry.

  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 other
  investment companies except if immediately thereafter not more than (i) 3%
  of the total outstanding voting stock of such company is owned by the Fund,
  (ii) 5% of the Fund's total assets, taken at market value, would be
  invested in any one such company, (iii) 10% of the Fund's total assets,
  taken at market value, would be invested in such securities, and (iv) the
  Fund, together with other investment companies having the same investment
  adviser and companies controlled by such companies, owns not more than 10%
  of the total outstanding stock of any one closed-end investment company.
 
    b. Mortgage, pledge, hypothecate or in any manner transfer, as security
  for indebtedness, any securities owned or held by the Fund except as may be
  necessary in connection with borrowings mentioned in investment restriction
  (3) above or except as may be necessary in connection with transactions in
  financial futures contracts and options thereon.
 
    c. Purchase any securities on margin, except that the Fund may obtain
  such short-term credit as may be necessary for the clearance of purchases
  and sales of portfolio securities (the deposit or payment by the Fund of
  initial or variation margin in connection with financial futures contracts
  and options thereon is not considered the purchase of a security on
  margin).
 
    d. Make short sales of securities or maintain a short position or invest
  in put, call, straddle or spread options, except that the Fund may write,
  purchase and sell options and futures on 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 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.
 
  For so long as AMPS are rated by Moody's, the Fund will not change these
additional investment restrictions unless it receives written confirmation
from Moody's that engaging in such transactions would not impair the rating
then assigned to the AMPS by Moody's.
 
  The Fund has no intention to file a voluntary application for relief under
Federal bankruptcy law or any similar application under state law for so long
as the Fund is solvent and does not foresee becoming insolvent.
 
  The Investment Adviser of the Fund and 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.

                              DESCRIPTION OF AMPS
 
  Certain of the capitalized terms used herein are defined in the Glossary
that appears at the back of the prospectus.
 
  The AMPS of each series will be preferred shares that entitle their holders
to receive dividends when, as and if declared by the Board of Trustees, out of
funds legally available therefor, at a rate per year that may vary for the
successive Dividend Periods for each such series. After the Initial Dividend
Period, each Subsequent Dividend Period for each series of AMPS generally will
be a 7-Day Dividend Period; provided, however, that prior to any Auction, the
Fund may elect, subject to certain limitations described herein, upon giving
notice to holders thereof, a Special Dividend Period. The Applicable Rate for
a particular Dividend Period will be determined by an Auction conducted on the
Business Day before the start of such Dividend Period. Beneficial Owners and
Potential Beneficial Owners of AMPS may participate in Auctions therefor,
although, except in the case of a Special Dividend Period, Beneficial Owners
desiring to continue to hold all of their AMPS regardless of the Applicable
Rate resulting from Auctions need not participate. For an explanation of
Auctions and the method of determining the Applicable Rate, see Appendix E--
"Auction Procedures."
 
  Except as otherwise required by law or unless there is no Securities
Depository, all outstanding AMPS of each series will be represented by one or
more certificates registered in the name of the nominee of the Securities
Depository (initially expected to be Cede), and no person acquiring AMPS will
be entitled to receive a certificate representing such shares. See Appendix
E--"Auction Procedures." As a result, the nominee of the Securities Depository
is expected to be the sole holder of record of the AMPS. Accordingly, each
purchaser of AMPS must rely on (i) the procedures of the Securities Depository
and, if such purchaser is not a member of the Securities Depository, such
purchaser's Agent Member, to receive dividends, distributions and notices and
to exercise voting rights (if and when applicable) and (ii) the records of the
Securities Depository and, if such purchaser is not a member of the Securities
Depository, such purchaser's Agent Member, to evidence its beneficial
ownership of AMPS.
 
  When issued and sold, the AMPS will have a liquidation preference of $25,000
per share plus an amount equal to accumulated but unpaid dividends (whether or
not earned or declared) and will be fully paid and non-assessable. See
"Description of AMPS--Liquidation Rights" in the prospectus. The AMPS will not
be convertible into common shares or other capital shares of the Fund, and the
holders thereof will have no preemptive rights. The AMPS of each series will
not be subject to any sinking fund but will be subject to redemption at the
option of the Fund at the Optional Redemption Price on any Dividend Payment
Date for such series (except during the Initial Dividend Period and during a
Non-Call Period) and, under certain circumstances, will be subject to
mandatory redemption by the Fund at the Mandatory Redemption Price stated in
the prospectus. See "Description of AMPS--Redemption" in the prospectus.
 
  In addition to serving as the Auction Agent in connection with the Auction
Procedures described in the prospectus, IBJ Whitehall Bank & Trust Company
will be the transfer agent, registrar, dividend disbursing agent and
redemption agent for the AMPS. The Auction Agent, however, will serve merely
as the agent of the Fund, acting in accordance with the Fund's instructions,
and will not be responsible for any evaluation or verification of any matters
certified to it.
 
  Except in an Auction, the Fund will have the right (to the extent permitted
by applicable law) to purchase or otherwise acquire any AMPS so long as the
Fund is current in the payment of dividends on AMPS and on any other capital
shares of the Fund ranking on a parity with the AMPS with respect to the
payment of dividends or upon liquidation.
 
  The following supplements the description of the terms of the AMPS set forth
in the prospectus. This description does not purport to be complete and is
subject to and qualified in its entirety by reference to the Fund's Charter
and Certificate of Designation, including the provisions thereof establishing
the AMPS. The
 
                                       9
<PAGE>
 
Fund's Charter and the form of Certificate of Designation establishing the
terms of the AMPS have been filed as exhibits to the Registration Statement of
which this statement of additional information is a part.
 
DIVIDENDS
 
  General. The holders of shares of each series of AMPS will be entitled to
receive, when, as and if declared by the Board of Trustees of the Fund, out of
funds legally available therefor, cumulative cash dividends on their shares,
at the Applicable Rate determined as set forth below under "Determination of
Dividend Rate," payable on the respective dates set forth below. Dividends on
the AMPS so declared and payable shall be paid (i) in preference to and in
priority over any dividends so declared and payable on the common shares, and
(ii) to the extent permitted under the Code and to the extent available, out
of net tax-exempt income earned on the Fund's investments. Generally,
dividends on AMPS, to the extent that they are derived from interest paid on
Municipal Bonds, will be exempt from Federal income taxes, subject to possible
application of the alternative minimum tax. See "Taxes."
 
  Notification of Dividend Period. In determining whether the Fund should
issue a Notice of Special Dividend for a series of AMPS, the Broker-Dealers
will consider (i) existing short-term and long-term market rates and indices
of such short-term and long-term rates, (ii) existing market supply and demand
for short-term and long-term securities, (iii) existing yield curves for
short-term and long-term securities comparable to the AMPS, (iv) industry and
financial conditions which may affect the AMPS, (v) the investment objective
of the Fund and (vi) the Dividend Periods and dividend rates at which current
and potential beneficial holders of the AMPS would remain or become beneficial
holders. If the Broker-Dealers shall not give the Fund and the Auction Agent a
Response by such second Business Day or if the Response states that given the
factors set forth above it is not advisable that the Fund give a Notice of
Special Dividend Period for the AMPS, the Fund may not give a Notice of
Special Dividend Period in respect of such Request for Special Dividend
Period. In the event the Response indicates that it is advisable that the Fund
give a Notice of Special Dividend Period for the AMPS, the Fund, by no later
than the second Business Day prior to such Auction Date, may give a notice (a
"Notice of Special Dividend Period") to the Auction Agent, the Securities
Depository and each Broker-Dealer, which notice will specify (i) the duration
of the Special Dividend Period, (ii) the Optional Redemption Price as
specified in the related Response and (iii) the Specific Redemption
Provisions, if any, as specified in the related Response. The Fund also shall
provide a copy of such Notice of Special Dividend Period to Moody's and S&P.
The Fund shall not give a Notice of Special Dividend Period, and, if such
Notice of Special Dividend Period shall have been given already, shall give
telephonic and written notice of its revocation (a "Notice of Revocation") to
the Auction Agent, each Broker-Dealer, and the Securities Depository on or
prior to the Business Day prior to the relevant Auction Date if (x) either the
1940 Act AMPS Asset Coverage is not satisfied or the Fund shall fail to
maintain S&P Eligible Assets and Moody's Eligible Assets each with an
aggregate Discounted Value at least equal to the AMPS Basic Maintenance
Amount, in each case on each of the two Valuation Dates immediately preceding
the Business Day prior to the relevant Auction Date on an actual basis and on
a pro forma basis giving effect to the proposed Special Dividend Period (using
as a pro forma dividend rate with respect to such Special Dividend Period the
dividend rate which the Broker-Dealers shall advise the Fund is an
approximately equal rate for securities similar to the AMPS with an equal
dividend period), provided that, in calculating the aggregate Discounted Value
of Moody's Eligible Assets for this purpose, the Moody's Exposure Period shall
be deemed to be one week longer, (y) sufficient funds for the payment of
dividends payable on the immediately succeeding Dividend Payment Date have not
been irrevocably deposited with the Auction Agent by the close of business on
the third Business Day preceding the related Auction Date or (z) the Broker-
Dealers jointly advise the Fund that, after consideration of the factors
listed above, they have concluded that it is advisable to give a Notice of
Revocation. The Fund also shall provide a copy of such Notice of Revocation to
Moody's and S&P. If the Fund is prohibited from giving a Notice of Special
Dividend Period as a result of the factors enumerated in clause (x), (y) or
(z) above or if the Fund gives a Notice of Revocation with respect to a Notice
of Special Dividend Period, the next succeeding Dividend Period for that
series will be a 7-Day Dividend Period. In addition, in the event Sufficient
Clearing Bids are not made in any Auction or an Auction is not held for any
reason, the next succeeding Dividend Period will be a 7-Day Dividend Period,
and the Fund may not again give a Notice of
 
                                      10
<PAGE>
 
Special Dividend Period (and any such attempted notice shall be null and void)
until Sufficient Clearing Bids have been made in an Auction with respect to a
7-Day Dividend Period.
 
  Non-Payment Period; Late Charge. A Non-Payment Period will commence if the
Fund fails to (i) declare, prior to the close of business on the second
Business Day preceding any Dividend Payment Date, for payment on or (to the
extent permitted as described below) within three Business Days after such
Dividend Payment Date to the persons who held such shares as of 12:00 noon,
Eastern time, on the Business Day preceding such Dividend Payment Date, the
full amount of any dividend on shares of AMPS payable on such Dividend Payment
Date or (ii) deposit, irrevocably in trust, in same-day funds, with the
Auction Agent by 12:00 noon, Eastern time, (A) on such Dividend Payment Date
the full amount of any cash dividend on such shares (if declared) payable on
such Dividend Payment Date or (B) on any redemption date for AMPS called for
redemption, the Mandatory Redemption Price per share of such AMPS or, in the
case of an optional redemption, the Optional Redemption Price per share. Such
Non-Payment Period will consist of the period commencing on and including the
aforementioned Dividend Payment Date or redemption date, as the case may be,
and ending on and including the Business Day on which, by 12:00 noon, Eastern
time, all unpaid cash dividends and unpaid redemption prices shall have been
so deposited or otherwise shall have been made available to the applicable
holders in same-day funds, provided that a Non-Payment Period for any series
of AMPS will not end unless the Fund shall have given at least five days' but
no more than 30 days' written notice of such deposit or availability to the
Auction Agent, the Securities Depository and all holders of AMPS of such
series. Notwithstanding the foregoing, the failure by the Fund to deposit
funds as provided for by clauses (ii) (A) or (ii) (B) above within three
Business Days after any Dividend Payment Date or redemption date, as the case
may be, in each case to the extent contemplated below, shall not constitute a
"Non-Payment Period."
 
  The Applicable Rate for each Dividend Period for AMPS of any series,
commencing during a Non-Payment Period, will be equal to the Non-Payment
Period Rate; and each Dividend Period commencing after the first day of, and
during, a Non-Payment Period shall be a 7-Day Dividend Period. Any dividend on
AMPS due on any Dividend Payment Date for such shares (if, prior to the close
of business on the second Business Day preceding such Dividend Payment Date,
the Fund has declared such dividend payable on such Dividend Payment Date to
the persons who held such shares as of 12:00 noon, Eastern time, on the
Business Day preceding such Dividend Payment Date) or redemption price with
respect to such shares not paid to such persons when due may be paid to such
persons in the same form of funds by 12:00 noon, Eastern time, on any of the
first three Business Days after such Dividend Payment Date or due date, as the
case may be, provided that such amount is accompanied by a late charge
calculated for such period of non-payment at the Non-Payment Period Rate
applied to the amount of such non-payment based on the actual number of days
comprising such period divided by 365. In the case of a willful failure of the
Fund to pay a dividend on a Dividend Payment Date or to redeem any AMPS on the
date set for such redemption, the preceding sentence shall not apply and the
Applicable Rate for the Dividend Period commencing during the Non-Payment
Period resulting from such failure shall be the Non-Payment Period Rate. For
the purposes of the foregoing, payment to a person in same-day funds on any
Business Day at any time will be considered equivalent to payment to that
person in New York Clearing House (next-day) funds at the same time on the
preceding Business Day, and any payment made after 12:00 noon, Eastern time,
on any Business Day shall be considered to have been made instead in the same
form of funds and to the same person before 12:00 noon, Eastern time, on the
next Business Day.
 
  The Non-Payment Period Rate initially will be 200% of the applicable
Reference Rate (or 275% of such rate if the Fund has provided notification to
the Auction Agent prior to the Auction establishing the Applicable Rate for
any dividend that net capital gains or other taxable income will be included
in such dividend on AMPS), provided that the Board of Trustees of the Fund
shall have the authority to adjust, modify, alter or change from time to time
the initial Non-Payment Period Rate if the Board of Trustees of the Fund
determines and Moody's and S&P (and any Substitute Rating Agency in lieu of
Moody's or S&P in the event either of such parties shall not rate the AMPS)
advise the Fund in writing that such adjustment, modification, alteration or
change will not adversely affect their then-current ratings on the AMPS.
 
 
                                      11
<PAGE>
 
  Restrictions on Dividends and Other Payments. For so long as any AMPS are
outstanding, the Fund will not declare, pay or set apart for payment any
dividend or other distribution (other than a dividend or distribution paid in
shares of, or options, warrants or rights to subscribe for or purchase, common
shares or other shares, if any, ranking junior to AMPS as to dividends or upon
liquidation) in respect of common shares or any other shares of the Fund
ranking junior to or on a parity with AMPS as to dividends or upon
liquidation, or call for redemption, redeem, purchase or otherwise acquire for
consideration any common shares or any other such junior shares (except by
conversion into or exchange for shares of the Fund ranking junior to AMPS as
to dividends and upon liquidation) or any such parity shares (except by
conversion into or exchange for shares of the Fund ranking junior to or on a
parity with AMPS as to dividends and upon liquidation), unless (A) immediately
after such transaction, the Fund would have S&P Eligible Assets and Moody's
Eligible Assets each with an aggregate Discounted Value equal to or greater
than the AMPS Basic Maintenance Amount, and the 1940 Act AMPS Asset Coverage
(see "Asset Maintenance" and "Redemption" below) would be satisfied, (B) full
cumulative dividends on AMPS due on or prior to the date of the transaction
have been declared and paid or shall have been declared and sufficient funds
for the payment thereof deposited with the Auction Agent, (C) any Additional
Dividend required to be paid on or before the date of such declaration or
payment has been paid and (D) the Fund has redeemed the full number of AMPS
required to be redeemed by any provision for mandatory redemption contained in
the Certificate of Designation.
 
ASSET MAINTENANCE
 
  1940 Act AMPS Asset Coverage. The Fund will be required under the
Certificate of Designation to maintain, with respect to AMPS, as of the last
Business Day of each month in which any AMPS are outstanding, asset coverage
of at least 200% with respect to senior securities which are shares, including
the AMPS (or such other asset coverage as in the future may be specified in or
under the 1940 Act as the minimum asset coverage for senior securities which
are stock of a closed-end investment company as a condition of paying
dividends on its common stock) ("1940 Act AMPS Asset Coverage"). If the Fund
fails to maintain 1940 Act AMPS Asset Coverage and such failure is not cured
as of the last Business Day of the following month (the "1940 Act Cure Date"),
the Fund will be required under certain circumstances to redeem certain of the
AMPS. See "Redemption" in the prospectus and below.
 
  AMPS Basic Maintenance Amount.  So long as AMPS are outstanding, the Fund
will be required under the Certificate of Designation to maintain as of each
Business Day (a "Valuation Date") S&P Eligible Assets and Moody's Eligible
Assets each having in the aggregate a Discounted Value at least equal to the
AMPS Basic Maintenance Amount. If the Fund fails to meet such requirement as
of any Valuation Date and such failure is not cured on or before the sixth
Business Day after such Valuation Date (the "AMPS Basic Maintenance Cure
Date"), the Fund will be required under certain circumstances to redeem
certain of the AMPS. Upon any failure to maintain the required Discounted
Value, the Fund will use its best efforts to alter the composition of its
portfolio to reattain a Discounted Value at least equal to the AMPS Basic
Maintenance Amount on or prior to the AMPS Basic Maintenance Cure Date. See
"Redemption" in the prospectus and below.
 
  The AMPS Basic Maintenance Amount as of any Valuation Date is defined as the
dollar amount equal to (i) the sum of (A) the product of the number of AMPS
outstanding on such Valuation Date multiplied by the sum of $25,000 and any
applicable redemption premium attributable to the designation of a Premium
Call Period; (B) the aggregate amount of cash dividends (whether or not earned
or declared) that will have accumulated for each share of AMPS outstanding to
(but not including) the end of the current Dividend Period that follows such
Valuation Date in the event the then-current Dividend Period will end within
49 calendar days of such Valuation Date or through the 49th day after such
Valuation Date in the event the then-current Dividend Period for each series
of AMPS will not end within 49 calendar days of such Valuation Date; (C) in
the event the then-current Dividend Period will end within 49 calendar days of
such Valuation Date, the aggregate amount of cash dividends that would
accumulate at the Maximum Applicable Rate applicable to a Dividend Period of
28 or fewer days on any AMPS outstanding from the end of such Dividend Period
through the 49th day after such Valuation Date, multiplied by the larger of
the Moody's Volatility Factor and the S&P Volatility Factor determined from
time to time by Moody's and S&P, respectively (except that if such Valuation
Date
 
                                      12
<PAGE>
 
occurs during a Non-Payment Period, the cash dividend for purposes of
calculation would accumulate at the then-current Non-Payment Period Rate); (D)
the amount of anticipated Fund expenses for the 90 days subsequent to such
Valuation Date (including any premiums payable with respect to a Policy); (E)
the amount of the Fund's Maximum Potential Additional Dividend Liability as of
such Valuation Date; and (F) any current liabilities as of such Valuation Date
to the extent not reflected in any of (i) (A) through (i) (E) (including,
without limitation, and immediately upon determination, any amounts due and
payable by the Fund pursuant to repurchase agreements, any amounts payable for
Florida Municipal Bonds or Municipal Bonds purchased as of such Valuation
Date) less (ii) either (A) the Discounted Value of any Fund assets, or (B) the
face value of any of the Fund's assets if such assets mature prior to or on
the date of redemption of AMPS or payment of a liability and are either
securities issued or guaranteed by the United States Government or Deposit
Securities, in both cases irrevocably deposited by the Fund for the payment of
the amount needed to redeem AMPS subject to redemption or to satisfy any of
(i) (B) through (i) (F). For Moody's and S&P the Fund shall include as a
liability an amount calculated semi-annually equal to 150% of the estimated
cost of obtaining other insurance guaranteeing the timely payment of interest
on a Moody's Eligible Asset or S&P Eligible Asset and principal thereof to
maturity with respect to Moody's Eligible Assets and S&P Eligible Assets that
(i) are covered by a Policy which provides the Fund with the option to obtain
such other insurance and (ii) are discounted by a Moody's Discount Factor or
S&P Discount Factor, as the case may be, determined by reference to the
insurance claims-paying ability rating of the issuer of such Policy. For
purposes of the foregoing, "Maximum Potential Additional Dividend Liability,"
as of any Valuation Date, means the aggregate amount of Additional Dividends
that would be due if the Fund were to make Retroactive Taxable Allocations,
with respect to any fiscal year, estimated based upon dividends paid and the
amount of undistributed realized net capital gains and other taxable income
earned by the Fund, as of the end of the calendar month immediately preceding
such Valuation Date and assuming such Additional Dividends are fully taxable.
 
  The Discount Factors and guidelines for determining the market value of the
Fund's portfolio holdings have been based on criteria established in
connection with rating the AMPS. These factors include, but are not limited
to, the sensitivity of the market value of the relevant asset to changes in
interest rates, the liquidity and depth of the market for the relevant asset,
the credit quality of the relevant asset (for example, the lower the rating of
a debt obligation, the higher the related discount factor) and the frequency
with which the relevant asset is marked to market. In no event shall the
Discounted Value of any asset of the Fund exceed its unpaid principal balance
or face amount as of the date of calculation. The Discount Factor relating to
any asset of the Fund and the AMPS Basic Maintenance Amount, the assets
eligible for inclusion in the calculation of the Discounted Value of the
Fund's portfolio and certain definitions and methods of calculation relating
thereto may be changed from time to time by the Fund, without shareholder
approval, but only in the event the Fund receives written confirmation from
S&P, Moody's and any Substitute Rating Agency that any such changes would not
impair the ratings then assigned to the AMPS by S&P or Moody's or any
Substitute Rating Agency.
 
  On or before the third Business Day after a Valuation Date on which the Fund
fails to maintain S&P Eligible Assets and Moody's Eligible Assets each with an
aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance
Amount, the Fund is required to deliver to the Auction Agent, Moody's and S&P
a report with respect to the calculation of the AMPS Basic Maintenance Amount
and the value of its portfolio holdings as of the date of such failure (an
"AMPS Basic Maintenance Report"). Additionally, on or before the third
Business Day after the first day of a Special Dividend Period, the Fund will
deliver an AMPS Basic Maintenance Report to S&P and the Auction Agent. The
Fund also will deliver an AMPS Basic Maintenance Report as of the twenty-first
day of the last month of each fiscal quarter of the Fund (or, if such day is
not a Business Day, the next succeeding Business Day) on or before the third
Business Day after such day. Within ten Business Days after delivery of such
report relating to the twenty-first day of the last month of each fiscal
quarter of the Fund, the Fund will deliver a letter prepared by the Fund's
independent accountants regarding the accuracy of the calculations made by the
Fund in its most recent AMPS Basic Maintenance Report. Also, on or before 5:00
p.m., Eastern time, on the first Business Day after common shares are
repurchased by the Fund, the Fund will complete and deliver to S&P and Moody's
an AMPS Basic Maintenance Report as of the close of business on such date that
common shares are repurchased. If any such letter prepared by the Fund's
independent accountants
 
                                      13
<PAGE>
 
shows that an error was made in the most recent AMPS Basic Maintenance Report,
the calculation or determination made by the Fund's independent accountants
will be conclusive and binding on the Fund.
 
REDEMPTION
 
  Mandatory Redemption. The number of AMPS to be redeemed will be equal to the
lesser of (a) the minimum number of AMPS the redemption of which, if deemed to
have occurred immediately prior to the opening of business on the Cure Date,
together with all other preferred shares subject to redemption or retirement,
would result in the Fund having S&P Eligible Assets and Moody's Eligible
Assets each with an aggregate Discounted Value equal to or greater than the
AMPS Basic Maintenance Amount or satisfaction of the 1940 Act AMPS Asset
Coverage, as the case may be, on such Cure Date (provided that, if there is no
such minimum number of shares the redemption of which would have such result,
all AMPS then outstanding will be redeemed), and (b) the maximum number of
AMPS, together with all other preferred shares subject to redemption or
retirement, that can be redeemed out of funds expected to be legally available
therefor on such redemption date. In determining the number of AMPS required
to be redeemed in accordance with the foregoing, the Fund shall allocate the
number required to be redeemed which would result in the Fund having S&P
Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted
Value equal to or greater than the AMPS Basic Maintenance Amount or
satisfaction of the 1940 Act AMPS Asset Coverage, as the case may be, pro rata
among AMPS and other preferred shares subject to redemption pursuant to
provisions similar to those set forth below; provided that, AMPS which may not
be redeemed at the option of the Fund due to the designation of a Non-Call
Period applicable to such shares (A) will be subject to mandatory redemption
only to the extent that other shares are not available to satisfy the number
of shares required to be redeemed and (B) will be selected for redemption in
an ascending order of outstanding number of days in the Non-Call Period (with
shares with the lowest number of days to be redeemed first) and by lot in the
event of shares having an equal number of days in such Non-Call Period. The
Fund is required to effect such a mandatory redemption not later than 35 days
after such Cure Date, except that if the Fund does not have funds legally
available for the redemption of all of the required number of AMPS which are
subject to mandatory redemption or the Fund otherwise is unable to effect such
redemption on or prior to 35 days after such Cure Date, the Fund will redeem
those AMPS which it was unable to redeem on the earliest practicable date on
which it is able to effect such redemption.
 
  Notice of Redemption. If AMPS of any series are to be redeemed, a notice of
redemption will be mailed to each record holder of such AMPS (initially Cede
as nominee of the Securities Depository) and to the Auction Agent not less
than 17 nor more than 30 days prior to the date fixed for the redemption
thereof. Each notice of redemption will include a statement setting forth: (i)
the redemption date, (ii) the aggregate number of AMPS of such series to be
redeemed, (iii) the redemption price, (iv) the place or places where AMPS of
such series are to be surrendered for payment of the redemption price, (v) a
statement that dividends on the shares to be redeemed will cease to accumulate
on such redemption date (except that holders may be entitled to Additional
Dividends) and (vi) the provision of the Certificate of Designation pursuant
to which such shares are being redeemed. The notice also will be published in
The Wall Street Journal. No defect in the notice of redemption or in the
mailing or publication thereof will affect the validity of the redemption
proceedings, except as required by applicable law.
 
  In the event that less than all of the outstanding shares of any series of
AMPS are to be redeemed, the shares to be redeemed will be selected by lot or
such other method as the Fund shall deem fair and equitable, and the results
thereof will be communicated to the Auction Agent. The Auction Agent will give
notice to the Securities Depository, whose nominee will be the record holder
of all AMPS, and the Securities Depository will determine the number of shares
to be redeemed from the account of the Agent Member of each Existing Holder.
Each Agent Member will determine the number of shares to be redeemed from the
account of each Existing Holder for which it acts as agent. An Agent Member
may select for redemption shares from the accounts of some Existing Holders
without selecting for redemption any shares from the accounts of other
Existing Holders. Notwithstanding the foregoing, if neither the Securities
Depository nor its nominee is the record holder of all of the shares of such
series, the particular shares to be redeemed shall be selected by the Fund by
lot or by such other method as the Fund shall deem fair and equitable.

  If the Fund gives notice of redemption, and concurrently or thereafter
deposits in trust with the Auction Agent, or segregates in an account at the
Fund's custodian bank for the benefit of the Auction Agent, Deposit
Securities(with a right of substitution) having an aggregate Discounted Value
(utilizing in the case of S&P and S&P Exposure Period of 22 Business Days)
equal to the redemption payment for the AMPS as to which notice of redemption
has been given, with irrevocable instructions and authority to pay the
redemption price to the record holders thereof, then upon the date of such
deposit or, if no such deposit is made, upon such date fixed for redemption
(unless the Fund shall default in making payment of the redemption price), all
rights of the holders of such shares called for redemption will cease and
terminate, except the right of such holders to receive the redemption price
thereof and any Additional Dividends, but without interest, and such shares no
longer will be deemed to be outstanding. The Fund will be entitled to receive,
from time to time, the interest, if any, earned on such Deposit Securities
deposited with the Auction Agent, and the holders of any shares so redeemed
will have no claim to any such interest. Any funds so deposited which are
unclaimed at the end of one year from such redemption date will be repaid,
upon demand, to the Fund, after which the holders of the AMPS of such series
so called for redemption may look only to the Fund for payment thereof.
 
  So long as any AMPS are held of record by the nominee of the Securities
Depository (initially Cede), the redemption price for such shares will be paid
on the redemption date to the nominee of the Securities Depository. The
Securities Depository's normal procedures now provide for it to distribute the
amount of the redemption price to Agent Members who, in turn, are expected to
distribute such funds to the persons for whom they are acting as agent.
 
  Notwithstanding the provisions for redemption described above, no AMPS shall
be subject to optional redemption (i) unless all dividends in arrears on the
outstanding AMPS, and all capital shares of the Fund ranking on a parity with
the AMPS with respect to the payment of dividends or upon liquidation, have
been or are being contemporaneously paid or declared and set aside for payment
and (ii) if redemption thereof would result in the Fund's failure to maintain
Moody's Eligible Assets or S&P Eligible Assets with an aggregate Discounted
Value equal to or greater than the AMPS Basic Maintenance Amount.
 
VOTING RIGHTS
 
  In connection with the election of the Fund's Trustees, holders of AMPS and
any other preferred shares, voting as a separate class, shall be entitled at
all times to elect two of the Fund's Trustees, and the remaining Trustees will
be elected by holders of common shares and AMPS and any other preferred
shares, voting together as a single class. In addition, if at any time
dividends on outstanding AMPS shall be unpaid in an amount equal to at least
two full years' dividends thereon or if at any time holders of any preferred
shares are entitled, together with the holders of AMPS, to elect a majority of
the Trustees of the Fund under the 1940 Act, then the number of Trustees
constituting the Board of Trustees automatically shall be increased by the
smallest number that, when added to the two Trustees elected exclusively by
the holders of AMPS and any other preferred shares as described above, would
constitute a majority of the Board of Trustees as so increased by such
smallest number, and at a special meeting of shareholders which will be called
and held as soon as practicable, and at all subsequent meetings at which
Trustees are to be elected, the holders of AMPS and any other preferred
shares, voting as a separate class, will be entitled to elect the smallest
number of additional Trustees that, together with the two Trustees which such
holders in any event will be entitled to elect, constitutes a majority of the
total number of Trustees of the Fund as so increased. The terms of office of
the persons who are Trustees at the time of that election will continue. If
the Fund thereafter shall pay, or declare and set apart for payment in full,
all dividends payable on all outstanding AMPS and any other preferred shares
for all past Dividend Periods, the additional voting rights of the holders of
AMPS and any other preferred shares as described above shall cease, and the
terms of office of all of the additional Trustees elected by the holders of
AMPS and any other preferred shares (but not of the Trustees with respect to
whose election the holders of common shares were entitled to vote or the two
Trustees the holders of AMPS and any other preferred shares have the right to
elect in any event) will terminate automatically.
 
 
                                      15
<PAGE>
 
  The affirmative vote of a majority of the votes entitled to be cast by
holders of outstanding AMPS and any other 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 the AMPS or any other series of preferred
shares with respect to the payment of dividends or the distribution of assets
on liquidation, or (ii) amend, alter or repeal the provisions of the
Declaration of Trust, whether by merger, consolidation or otherwise, so as to
adversely affect any of the contract rights expressly set forth in the
Declaration of Trust of holders of AMPS or any other preferred shares. To the
extent permitted under the 1940 Act, in the event shares of more than one
series of AMPS are outstanding, the Fund shall not approve any of the actions
set forth in clause (i) or (ii) which adversely affects the contract rights
expressly set forth in the Declaration of Trust of a holder of shares of a
series of AMPS differently than those of a holder of shares of any other
series of AMPS without the affirmative vote of at least a majority of votes
entitled to be cast by holders of the AMPS of each series adversely affected
and outstanding at such time (each such adversely affected series voting
separately as a class). The Board of Trustees, however, without shareholder
approval, may amend, alter or repeal any or all of the various rating agency
guidelines described herein in the event the Fund receives confirmation from
the rating agencies that any such amendment, alteration or repeal would not
impair the ratings then assigned to AMPS. Unless a higher percentage is
provided for under "Description of Capital Shares--Certain Provisions of the
Declaration of Trust" in the prospectus, the affirmative vote of a majority of
the votes entitled to be cast by holders of outstanding AMPS and any other
preferred shares, voting as a separate class, will be required to approve any
plan of reorganization (including bankruptcy proceedings) adversely affecting
such shares or any action requiring a vote of security holders under Section
13(a) of the 1940 Act including, among other things, changes in the Fund's
investment objective or changes in the investment restrictions described as
fundamental policies under "Investment Objective and Policies." The class vote
of holders of AMPS and any other preferred shares described above in each case
will be in addition to a separate vote of the requisite percentage of shares
of common shares and shares of AMPS and any other preferred shares, voting
together as a single class, necessary to authorize the action in question.
 
  The foregoing voting provisions will not apply to any series of AMPS if, at
or prior to the time when the act with respect to which such vote otherwise
would be required shall be effected, such shares shall have been (i) redeemed
or (ii) called for redemption and sufficient funds shall have been deposited
in trust to effect such redemption.
 
                                  THE AUCTION
 
AUCTION AGENT AGREEMENT
 
  The Auction Agent will act as agent for the Fund in connection with
Auctions. In the absence of bad faith or negligence on its part, the Auction
Agent will not be liable for any action taken, suffered or omitted, or for any
error of judgment made, by it in the performance of its duties under the
Auction Agent Agreement, and will not be liable for any error of judgment made
in good faith unless the Auction Agent shall have been negligent in
ascertaining the pertinent facts. Pursuant to the Auction Agent Agreement, the
Fund is required to indemnify the Auction Agent for certain losses and
liabilities incurred by the Auction Agent without negligence or bad faith on
its part in connection with the performance of its duties under such
agreement.
 
  The Auction Agent may terminate the Auction Agent Agreement upon notice to
the Fund, which termination may be no earlier than 60 days following delivery
of such notice. If the Auction Agent resigns, the Fund will use its best
efforts to enter into an agreement with a successor Auction Agent containing
substantially the same terms and conditions as the Auction Agent Agreement.
The Fund may terminate the Auction Agent Agreement, provided that prior to
such termination the Fund shall have entered into such an agreement with
respect thereto with a successor Auction Agent.
 
BROKER-DEALER AGREEMENTS
 
  The Auctions require the participation of one or more broker-dealers. A
Broker-Dealer Agreement may be terminated by the Auction Agent or a Broker-
Dealer on five days' notice to the other party, provided that the Broker-
Dealer Agreement with Merrill Lynch may not be terminated without the prior
written consent of the Fund, which consent may not be unreasonably withheld.

AUCTION PROCEDURES
 
  Separate auctions will be conducted for each series of AMPS. The Auction
Procedures are set forth in Appendix E to this statement of additional
information. The Settlement Procedures to be used with respect to Auctions are
set forth in Appendix D to this statement of additional information.
 
                           RATING AGENCY GUIDELINES
 
S&P AAA RATING GUIDELINES
 
  The Discounted Value of the Fund's S&P Eligible Assets is calculated on each
Valuation Date. See "Description of AMPS--Asset Maintenance--AMPS Basic
Maintenance Amount." S&P Eligible Assets include cash, Receivables for Florida
Municipal Bonds Sold (as defined below) and Florida Municipal Bonds or
Municipal Bonds eligible for consideration under S&P's current guidelines. For
purposes of calculating the Discounted Value of the Fund's portfolio under
current S&P guidelines, the fair market value of Florida Municipal Bonds or
Municipal Bonds eligible for consideration under such guidelines must be
discounted by the applicable S&P Discount Factor set forth in the table below.
The Discounted Value of a Florida Municipal Bond or Municipal Bond eligible
for consideration under S&P guidelines is the fair market value thereof
divided by the S&P Discount Factor. The S&P Discount Factor used to discount a
particular Florida Municipal Bond or Municipal Bond will be determined by
reference to (a)(i) the rating by S&P, Moody's or Fitch on such Bond or (ii)
in the event the Florida Municipal Bond is insured under a Policy and the
terms of the Policy permit the Fund, at its option, to obtain other permanent
insurance guaranteeing the timely payment of interest on such Florida
Municipal Bond and principal thereof to maturity, the S&P insurance claims-
paying ability rating of the issuer of the Policy or (iii) in the event the
Florida Municipal Bond is insured under an insurance policy which guarantees
the timely payment of interest on such Florida Municipal Bond and principal
thereof to maturity, the S&P insurance claims-paying ability rating of the
issuer of the insurance policy and (b) the S&P Exposure Period. The S&P
Exposure Period is the maximum period of time following a Valuation Date,
including the Valuation Date and the AMPS Basic Maintenance Cure Date, that
the Fund has to cure any failure to maintain, as of such Valuation Date, a
Discounted Value for its portfolio at least equal to the AMPS Basic
Maintenance Amount.
 
  S&P Discount Factors applicable to Florida Municipal Bonds for a range of
S&P Exposure Periods are set forth below:

  Since the S&P Exposure Period currently applicable to the Fund is seven
Business Days, the S&P Discount Factors currently applicable to Municipal
Bonds eligible for consideration under S&P guidelines will be determined by
reference to the factors set forth opposite the exposure period line entitled
"7 Business Days." Notwithstanding the foregoing, (i) the S&P Discount Factor
for short-term Florida Municipal Bonds will be 115%, so long as such Florida
Municipal Bonds are rated A-1+ or SP-1+ by S&P and mature or have a demand
feature exercisable in 30 days or less, or 120% so long as such Florida
Municipal Bonds are rated A-1 or SP-1 by S&P and mature or have a demand
feature exercisable in 30 days or less, or 125% if such Florida Municipal
Bonds are not rated by S&P but are rated VMIG-1, P-1 or MIG-1 by Moody's or F-
1+ by Fitch; provided, however, such short-term Florida Municipal Bonds rated
by Moody's or Fitch but not rated by S&P having a demand feature exercisable
in 30 days or less must be backed by a letter of credit, liquidity facility or
guarantee from a bank or other financial institution having a short-term
rating of at least A-1+ from S&P; and further
 
                                      17
<PAGE>
 
provided that such short-term Florida Municipal Bonds rated by Moody's or
Fitch but not rated by S&P may comprise no more than 50% of short-term Florida
Municipal Bonds that qualify as S&P Eligible Assets, (ii) the S&P Discount
Factor for Receivables for Florida Municipal Bonds Sold that are due in more
than five Business Days from such Valuation Date will be the S&P Discount
Factor applicable to the Florida Municipal Bonds sold, and (iii) no S&P
Discount Factor will be applied to cash or to Receivables for Florida
Municipal Bonds Sold if such receivables are due within five Business Days of
such Valuation Date. "Receivables for Florida Municipal Bonds Sold," for
purposes of calculating S&P Eligible Assets as of any Valuation Date, means
the book value of receivables for Florida Municipal Bonds sold as of or prior
to such Valuation Date. The Fund may adopt S&P Discount Factors for Municipal
Bonds other than Florida Municipal Bonds provided that S&P advises the Fund in
writing that such action will not adversely affect its then current rating on
the AMPS. For purposes of the foregoing, Anticipation Notes rated SP-1 or, if
not rated by S&P, rated VMIG-1 by Moody's or F-1+ by Fitch, which do not
mature or have a demand feature exercisable in 30 days and which do not have a
long-term rating, shall be considered to be short-term Florida Municipal
Bonds.
 
  The S&P guidelines require certain minimum issue size and geographical
diversification and impose other requirements for purposes of determining S&P
Eligible Assets. In order to be considered S&P Eligible Assets, Municipal
Bonds must:
 
    (i) be interest bearing and pay interest at least semi-annually;
 
    (ii) be payable with respect to principal and interest in U.S. dollars;
 
    (iii) be publicly rated BBB or higher by S&P or, except in the case of
  Anticipation Notes that are grant anticipation notes or bond anticipation
  notes, which must be rated by S&P to be included in S&P Eligible Assets, if
  not rated by S&P but rated by Moody's or Fitch, be rated at least A by
  Moody's or Fitch (provided that such Moody's-rated or Fitch-rated Florida
  Municipal Bonds will be included in S&P Eligible Assets only to the extent
  the fair market value of such Florida Municipal Bonds does not exceed 50%
  of the aggregate fair market value of the S&P Eligible Assets. For purposes
  of determining the S&P Discount Factors applicable to any such Moody's-
  rated or Fitch-rated Municipal Bonds, such Florida Municipal Bonds will be
  deemed to have an S&P rating that is one full rating category lower than
  its Moody's rating or Fitch rating);
 
    (iv) not be subject to a covered call or covered put option written by
  the Fund;
 
    (v) except for inverse floating obligations, not be part of a private
  placement of Municipal Bonds; and
 
    (vi) except for inverse floating obligations, be part of an issue with an
  original issue size of at least $10 million or, if of an issue with an
  original issue size below $10 million (but in no event below $5 million),
  be either (a) issued by an issuer with a total of at least $25 million of
  securities outstanding or (b) rated at least A by S&P with all such Florida
  Municipal Bonds not constituting more than 20% of the aggregate market
  value of S&P Eligible Assets.
 
  Notwithstanding the foregoing:
 
    (i) Florida Municipal Bonds of any one issuer or guarantor (excluding
  bond insurers) will be considered S&P Eligible Assets only to the extent
  the fair market value of such Bonds does not exceed 10% of the aggregate
  fair market value of the S&P Eligible Assets, provided that 2% is added to
  the applicable S&P Discount Factor for every 1% by which the fair market
  value of such Florida Municipal Bonds exceeds 5% of the aggregate fair
  market value of the S&P Eligible Assets;
 
    (ii) Florida Municipal Bonds of any one issue type category (as described
  below) will be considered S&P Eligible Assets only to the extent the market
  value of such Florida Municipal Bonds does not exceed 25% of the aggregate
  market value of S&P Eligible Assets, except that Florida Municipal Bonds
  falling within the utility issue type category will be broken down into
  three sub-categories (as described below) and such Florida Municipal Bonds
  will be considered S&P Eligible Assets to the extent the market value of
  such Florida Municipal Bonds in each such sub-category does not exceed 25%
  of the aggregate market value of S&P Eligible Assets, except that Florida
  Municipal Bonds falling within the transportation issue type category will
  be broken down into two sub-categories (as described below) and such
  Florida Municipal
 
                                      18
<PAGE>
 
  Bonds will be considered S&P Eligible Assets to the extent the market value
  of such Bonds in both sub-categories combined (as described below) does not
  exceed 40% of the aggregate market value of S&P Eligible Assets and except
  that Florida Municipal Bonds falling within the general obligation issue
  type category will be considered S&P Eligible Assets to the extent the
  market value of such Florida Municipal Bonds does not exceed 50% of the
  aggregate market value of S&P Eligible Assets. For purposes of the issue
  type category requirement described above, Florida Municipal Bonds will be
  classified within one of the following categories: health care issues,
  housing issues, educational facilities issues, student loan issues,
  transportation issues, industrial development bond issues, utility issues,
  general obligation issues, lease obligations, escrowed bonds and other
  issues not falling within one of the aforementioned categories. The general
  obligation issue type category includes any issuer that is directly or
  indirectly guaranteed by the State of Florida or its political
  subdivisions. Utility issuers are included in the general obligation issue
  type category if the issuer is directly or indirectly guaranteed by the
  State of Florida or its political subdivisions. For purposes of the issue
  type category requirement described above, Florida Municipal Bonds in the
  utility issue type category will be classified within one of the three
  following sub-categories: (1) electric, gas and combination issues (if the
  combination issue includes an electric issue), (2) water and sewer
  utilities and combination issues (if the combination issue does not include
  an electric issue), and (3) irrigation, resource recovery, solid waste and
  other utilities, provided that Florida Municipal Bonds included in this
  sub-category (iii) must be rated by S&P in order to be included in S&P
  Eligible Assets. For purposes of the issue type category requirement
  described above, Florida Municipal Bonds in the transportation issue type
  category will be classified within one of the two following sub-categories:
  (i) streets and highways, toll roads, bridges and tunnels, airports and
  multi-purpose port authorities (multiple revenue streams generated by toll
  roads, airports, real estate, bridges), (ii) mass transit, parking,
  seaports and others. Exposure to transportation sub-category (1) in the
  preceding sentence is limited to 25% of the aggregate market value of S&P
  Eligible Assets, provided, however, exposure to transportation sub-category
  (2) in the preceding sentence can exceed the 25% limit to the extent that
  exposure to transportation sub-category (2) is reduced, for a total
  exposure up to and not exceeding 40% of the aggregate market value of S&P
  Eligible Assets for the transportation issue type category; and
 
    (iii) Florida Municipal Bonds which are escrow bonds or defeased bonds
  may compose up to 100% of the aggregate market value of S&P Eligible Assets
  if such Florida Municipal Bonds initially are assigned a rating by S&P in
  accordance with S&P's legal defeasance criteria or rerated by S&P as
  economic defeased escrow bonds and assigned an AAA rating. Florida
  Municipal Bonds may be rated as escrow bonds by another nationally
  recognized rating agency or rerated as an escrow bond and assigned the
  equivalent of an S&P AAA rating, provided that such equivalent rated
  Florida Municipal Bonds are limited to 50% of the aggregate market value of
  S&P Eligible Assets and are deemed to have an AA S&P rating for purposes of
  determining the S&P Discount Factor applicable to such Florida Municipal
  Bonds. The limitations on Florida Municipal Bonds of any one issuer in
  clause (i) above is not applicable to escrow bonds, however, economically
  defeased bonds that are either initially rated or rerated by S&P or another
  nationally recognized rating agency and assigned the same rating level as
  the issuer of the Florida Municipal Bonds will remain in its original issue
  type category set forth in clause (ii) above. Florida Municipal Bonds that
  are legally defeased and secured by securities issued or guaranteed by the
  United States Government are not required to meet the minimum issuance size
  requirement set forth above.
 
  The Fund may include Municipal Bonds other than Florida Municipal Bonds as
S&P Eligible Assets pursuant to guidelines and restrictions to be established
by S&P, provided that S&P advises the Fund in writing that such action will
not adversely affect its then-current rating on the AMPS.
 
  As discussed in the prospectus, the Fund may engage in options or futures
transactions. For so long as any AMPS are rated by S&P, the Fund will not
purchase or sell financial futures contracts, write, purchase or sell options
on financial futures contracts or write put options (except covered put
options) or call options (except covered call options) on portfolio securities
unless it receives written confirmation from S&P that engaging in such
transactions will not impair the ratings then assigned to the AMPS by S&P,
except that the Fund may purchase or sell financial futures contracts based on
the Bond Buyer Municipal Bond Index (the "Municipal
 
                                      19
<PAGE>
 
Index") or United States Treasury Bonds or Notes ("Treasury Bonds") and write,
purchase or sell put and call options on such contracts (collectively "S&P
Hedging Transactions"), subject to the following limitations:
 
    (i) the Fund will not engage in any S&P Hedging Transaction based on the
  Municipal Index (other than transactions that terminate a financial futures
  contract or option held by the Fund by the Fund's taking an opposite
  position thereto ("Closing Transactions")), that would cause the Fund at
  the time of such transaction to own or have sold the least of (A) more than
  1,000 outstanding financial futures contracts based on the Municipal Index,
  (B) outstanding financial futures contracts based on the Municipal Index
  exceeding in number 25% of the quotient of the fair market value of the
  Fund's total assets divided by $1,000 or (C) outstanding financial futures
  contracts based on the Municipal Index exceeding in number 10% of the
  average number of daily traded financial futures contracts based on the
  Municipal Index in the 30 days preceding the time of effecting such
  transaction as reported by The Wall Street Journal;
 
    (ii) the Fund will not engage in any S&P Hedging Transaction based on
  Treasury Bonds (other than Closing Transactions) that would cause the Fund
  at the time of such transaction to own or have sold the lesser of (A)
  outstanding financial futures contracts based on Treasury Bonds and on the
  Municipal Index exceeding in number 25% of the quotient of the fair market
  value of the Fund's total assets divided by $100,000 ($200,000 in the case
  of the two-year United States Treasury Note) or (B) outstanding financial
  futures contracts based on Treasury Bonds exceeding in number 10% of the
  average number of daily traded financial futures contracts based on
  Treasury Bonds in the 30 days preceding the time of effecting such
  transaction as reported by The Wall Street Journal;
 
    (iii) the Fund will engage in Closing Transactions to close out any
  outstanding financial futures contract that the Fund owns or has sold or
  any outstanding option thereon owned by the Fund in the event (A) the Fund
  does not have S&P Eligible Assets with an aggregate Discounted Value equal
  to or greater than the AMPS Basic Maintenance Amount on two consecutive
  Valuation Dates and (B) the Fund is required to pay Variation Margin on the
  second such Valuation Date;
 
    (iv) the Fund will engage in a Closing Transaction to close out any
  outstanding financial futures contract or option thereon in the month prior
  to the delivery month under the terms of such financial futures contract or
  option thereon unless the Fund holds the securities deliverable under such
  terms; and
 
    (v) when the Fund writes a financial futures contract or an option
  thereon, it will either maintain an amount of cash, cash equivalents or
  high grade (rated A or better by S&P) fixed-income securities in a
  segregated account with the Fund's custodian, so that the amount so
  segregated plus the amount of Initial Margin and Variation Margin held in
  the account of or on behalf of the Fund's broker with respect to such
  financial futures contract or option equals the fair market value of the
  financial futures contract or option, or, in the event the Fund writes a
  financial futures contract or option thereon that requires delivery of an
  underlying security, it shall hold such underlying security in its
  portfolio.
 
  For purposes of determining whether the Fund has S&P Eligible Assets with a
Discounted Value that equals or exceeds the AMPS Basic Maintenance Amount, the
Discounted Value of cash or securities held for the payment of Initial Margin
or Variation Margin shall be zero and the aggregate Discounted Value of S&P
Eligible Assets shall be reduced by an amount equal to (i) 30% of the
aggregate settlement value, as marked to market, of any outstanding financial
futures contracts based on the Municipal Index that are owned by the Fund plus
(ii) 25% of the aggregate settlement value, as marked to market, of any
outstanding financial futures contracts based on Treasury Bonds which
contracts are owned by the Fund.
 
MOODY'S "aaa" RATING GUIDELINES
 
  The Discounted Value of the Fund's Moody's Eligible Assets is calculated on
each Valuation Date. See "Description of AMPS--Asset Maintenance--AMPS Basic
Maintenance Amount" herein. Moody's Eligible Assets include cash, Receivables
for Florida Municipal Bonds or Municipal Bonds (as defined below), and Florida
Municipal Bonds or Municipal Bonds eligible for consideration under Moody's
guidelines. For purposes of calculating the Discounted Value of the Fund's
portfolio under current Moody's guidelines, the fair market
 
                                      20
<PAGE>
 
value of Municipal Bonds eligible for consideration under such guidelines must
be discounted by the applicable Moody's Discount Factor set forth in the table
below. The Discounted Value of a Municipal Bond eligible for consideration
under Moody's guidelines is the lower of par and the quotient of the fair
market value thereof divided by the Moody's Discount Factor. The Moody's
Discount Factor used to discount a particular Florida Municipal Bond or
Municipal Bond will be determined by reference to (a) (i) the rating by
Moody's or S&P on such Bond or (ii) in the event the Moody's Eligible Asset is
insured under a Policy and the terms of the Policy permit the Fund, at its
option, to obtain other insurance guaranteeing the timely payment of interest
on such Moody's Eligible Asset and principal thereof to maturity, the Moody's
insurance claims-paying ability rating of the issuer of the Policy or (iii) in
the event the Moody's Eligible Asset is insured under an insurance policy
which guarantees the timely payment of interest on such Moody's Eligible Asset
and principal thereof to maturity, the Moody's insurance claims-paying ability
rating of the issuer of the insurance policy (provided that for purposes of
clauses (ii) and (iii) if the insurance claims-paying ability of an issuer of
a Policy or insurance policy is not rated by Moody's but is rated by S&P, such
issuer shall be deemed to have a Moody's insurance claims-paying ability
rating which is two full categories lower than the S&P insurance claims-paying
ability rating) and (b) the Moody's Exposure Period. Moody's Discount Factors

(1) Moody's rating.
(2) Florida Municipal Bonds and Municipal Bonds not rated by Moody's but rated
    BBB or BBB+ by S&P.
(3) Florida Municipal Bonds and Municipal Bonds rated MIG-1, VMIG-1 or P-1 or,
    if not rated by Moody's, rated SP-1+ or A-1+ by S&P which do not mature or
    have a demand feature at par exercisable within the Moody's Exposure
    Period and which do not have a long-term rating. For the purposes of the
    definition of Moody's Eligible Assets, these securities will have an
    assumed rating of A by Moody's.
 
provided, however, in the event a Moody's Discount Factor applicable to a
Moody's Eligible Asset is determined by reference to an insurance claims-
paying ability rating in accordance with clause (a)(ii) or (a)(iii), such
Moody's Discount Factor shall be increased by an amount equal to 50% of the
difference between (a) the percentage set forth in the foregoing table under
the applicable rating category and (b) the percentage set forth in the
foregoing table under the rating category which is one category lower than the
applicable rating category.
 
  Since the Moody's Exposure Period currently is 49 days, the Moody's Discount
Factors currently applicable to Municipal Bonds eligible for consideration
under Moody's guidelines will be determined by reference to the factors set
forth opposite the exposure period line entitled "7 weeks or less."
Notwithstanding the foregoing, (i) no Moody's Discount Factor will be applied
to short-term Florida Municipal Bonds and short-term Municipal Bonds, so long
as such Florida Municipal Bonds and Municipal Bonds are rated at least MIG-1,
VMIG-1 or P-1 by Moody's and mature or have a demand feature at par
exercisable within the Moody's Exposure Period, and the Moody's Discount
Factor for such Bonds will be 125% if such Bonds are not rated by Moody's but
are rated A-1+, SP-1+ or AA by S&P and mature or have a demand feature at par
exercisable within the Moody's Exposure Period, and (ii) no Moody's Discount
Factor will be applied to cash or to Receivables for Florida Municipal Bonds
or Municipal Bonds Sold. "Receivables for Florida Municipal Bonds or Municipal
Bonds Sold," for purposes of calculating Moody's Eligible Assets as of any
Valuation Date, means no more than the aggregate of the following: (i) the
book value of receivables for Florida Municipal Bonds or Municipal Bonds sold
as of or prior to such Valuation Date if such receivables are due within five
Business Days of such Valuation Date, and if the trades which generated such
receivables are (A) settled through clearing house firms with respect to which
the Fund has received prior written authorization from Moody's or (B) with
counterparties having a
 
                                      21
<PAGE>
 
Moody's long-term debt rating of at least Baa3; and (ii) the Moody's
Discounted Value of Florida Municipal Bonds or Municipal Bonds sold as of or
prior to such Valuation Date that generated receivables, if such receivables
are due within five Business Days of such Valuation Date but do not comply
with either of conditions (A) or (B) of the preceding clause (i).
 
  The Moody's guidelines impose certain requirements as to minimum issue size,
issuer diversification and geographical concentration, as well as other
requirements for purposes of determining whether Florida Municipal Bonds or
Municipal Bonds constitute Moody's Eligible Assets, as set forth in the table
below:

(1) The referenced percentages represent maximum cumulative totals for the
    related rating category and each lower rating category.
(2) Florida Municipal Bonds and Municipal Bonds not rated by Moody's but rated
    BBB or BBB+ by S&P.
(3) Does not apply to general obligation bonds.
(4) Applicable to general obligation bonds only.
(5) Does not apply to Florida Municipal Bonds. Territorial bonds (other than
    those issued by Puerto Rico and counted collectively) are each limited to
    10% of Moody's Eligible Assets. For diversification purposes, Puerto Rico
    will be treated as a state.
 
  For purposes of the maximum underlying obligor requirement described above,
any Florida Municipal Bond or Municipal Bond backed by the guaranty, letter of
credit or insurance issued by a third party will be deemed to be issued by
such third party if the issuance of such third party credit is the sole
determinant of the rating on such Bond. For purposes of the issue type
concentration requirement described above, Florida Municipal Bonds and
Municipal Bonds will be classified within one of the following categories:
health care issues (teaching and non-teaching hospitals, public and private),
housing issues (single-and multi-family), educational facilities issues
(public and private schools), student loan issues, resource recovery issues,
transportation issues (mass transit, airport and highway bonds), industrial
revenue/pollution control bond issues, utility issues (including water, sewer
and electricity), general obligation issues, lease obligations/certificates of
participation, escrowed bonds and other issues ("Other Issues") not falling
within one of the aforementioned categories (includes special obligations to
crossover, excise and sales tax revenue, recreation revenue, special
assessment and telephone revenue bonds). In no event shall (a) more than 10%
of Moody's Eligible Assets consist of student loan issues, (b) more than 10%
of Moody's Eligible Assets consist of recovery issues or (c) more than 10% of
Moody's Eligible Assets consist of Other Issues.
 
  Current Moody's guidelines also require that Florida Municipal Bonds or
Municipal Bonds constituting Moody's Eligible Assets pay interest in cash, be
publicly rated Baa or higher by Moody's or, if not rated by Moody's but rated
by S&P, that they be rated at least BBB by S&P, not have suspended ratings by
Moody's and be part of an issue of Florida Municipal Bonds or Municipal Bonds
of at least $10,000,000. For purposes of determining the Moody's Discount
Factors applicable to any such S&P-rated Florida Municipal Bonds or S&P-rated
Municipal Bonds, such Florida Municipal Bonds or Municipal Bonds (excluding
any short-term Municipal Bonds) will be deemed to have a Moody's rating that
is one full rating category lower than its S&P rating. When the Fund sells a
Florida Municipal Bond or Municipal Bond and agrees to repurchase it at a
future date, the Discounted Value of such Municipal Bond will constitute a
Moody's Eligible Asset and the amount the Fund is required to pay upon
repurchase of such bond will count as a liability for purposes of calculating
the AMPS Basic Maintenance Amount. When the Fund purchases a Florida Municipal
Bond or Municipal Bond and agrees
 
                                      22
<PAGE>
 
to sell it at a future date to another party, cash receivable by the Fund
thereby will constitute a Moody's Eligible Asset if the long-term debt of such
other party is rated at least A2 by Moody's and such agreement has a term of
30 days or less; otherwise the Discounted Value of such Bond will constitute a
Moody's Eligible Asset.
 
  Notwithstanding the foregoing, an asset will not be considered a Moody's
Eligible Asset if it is (i) held in a margin account, (ii) subject to any
material lien, mortgage, pledge, security interest or security agreement of
any kind, (iii) held for the purchase of a security pursuant to a Forward
Commitment or (iv) irrevocably deposited by the Fund for the payment of
dividends or redemption.
 
  For so long as AMPS are rated by Moody's, in managing the Fund's portfolio,
the Investment Adviser will not alter the composition of the Fund's portfolio
if, in the reasonable belief of the Investment Adviser, the effect of any such
alteration would be to cause the Fund to have Moody's Eligible Assets with an
aggregate Discounted Value, as of the immediately preceding Valuation Date,
less than the AMPS Basic Maintenance Amount as of such Valuation Date;
provided, however, that in the event that, as of the immediately preceding
Valuation Date, the aggregate Discounted Value of Moody's Eligible Assets
exceeded the AMPS Basic Maintenance Amount by five percent or less, the
Investment Adviser will not alter the composition of the Fund's portfolio in a
manner reasonably expected to reduce the aggregate Discounted Value of Moody's
Eligible Assets unless the Fund shall have confirmed that, after giving effect
to such alteration, the aggregate Discounted Value of Moody's Eligible Assets
would exceed the AMPS Basic Maintenance Amount.
 
  For so long as any AMPS are rated by Moody's, the Fund will not buy or sell
financial futures contracts, write, purchase or sell call options on financial
futures contracts or purchase put options on financial futures contracts or
write call options (except covered call options) on portfolio securities
unless it receives written confirmation from Moody's that engaging in such
transactions would not impair the ratings then assigned to the AMPS by
Moody's, except that the Fund may purchase or sell exchange-traded financial
futures contracts based on the Municipal Index or Treasury Bonds, and
purchase, write or sell exchange-traded put options on such financial futures
contracts, and purchase, write or sell exchange-traded call options on such
financial futures contracts (collectively "Moody's Hedging Transactions"),
subject to the following limitations:
 
    (i) the Fund will not engage in any Moody's Hedging Transaction based on
  the Municipal Index (other than Closing Transactions) that would cause the
  Fund at the time of such transaction to own or have sold (A) outstanding
  financial futures contracts based on the Municipal Index exceeding in
  number 10% of the average number of daily traded financial futures
  contracts based on the Municipal Index in the 30 days preceding the time of
  effecting such transaction as reported by The Wall Street Journal or (B)
  outstanding financial futures contracts based on the Municipal Index having
  a Market Value exceeding 50% of the Market Value of all Municipal Bonds
  constituting Moody's Eligible Assets owned by the Fund (other than Moody's
  Eligible Assets already subject to a Moody's Hedging Transaction);
 
    (ii) the Fund will not engage in any Moody's Hedging Transaction based on
  Treasury Bonds (other than Closing Transactions) that would cause the Fund
  at the time of such transaction to own or have sold (A) outstanding
  financial futures contracts based on Treasury Bonds having an aggregate
  Market Value exceeding 20% of the aggregate Market Value of Moody's
  Eligible Assets owned by the Fund and rated Aa by Moody's (or, if not rated
  by Moody's but rated by S&P, rated AAA by S&P) or (B) outstanding financial
  futures contracts based on Treasury Bonds having an aggregate fair market
  value exceeding 40% of the aggregate fair market value of all Municipal
  Bonds constituting Moody's Eligible Assets owned by the Fund (other than
  Moody's Eligible Assets already subject to a Moody's Hedging Transaction)
  and rated Baa or A by Moody's (or, if not rated by Moody's but rated by
  S&P, rated A or AA by S&P) (for purposes of the foregoing clauses (i) and
  (ii), the Fund shall be deemed to own the number of financial futures
  contracts that underlie any outstanding options written by the Fund);
 
    (iii) the Fund will engage in Closing Transactions to close out any
  outstanding financial futures contract based on the Municipal Index if the
  amount of open interest in the Municipal Index as reported by The Wall
  Street Journal is less than 5,000;
 
                                      23
<PAGE>
 
    (iv) the Fund will engage in a Closing Transaction to close out any
  outstanding financial futures contract by no later than the fifth Business
  Day of the month in which such contract expires and will engage in a
  Closing Transaction to close out any outstanding option on a financial
  futures contract by no later than the first Business Day of the month in
  which such option expires; (v) the Fund will engage in Moody's Hedging
  Transactions only with respect to financial futures contracts or options
  thereon having the next settlement date or the settlement date immediately
  thereafter;
 
    (v) the Fund will not engage in options and futures transactions for
  leveraging or speculative purposes and will not write any call options or
  sell any financial futures contracts for the purpose of hedging the
  anticipated purchase of an asset prior to completion of such purchase; and
 
    (vi) the Fund will not enter into an option or futures transaction
  unless, after giving effect thereto, the Fund would continue to have
  Moody's Eligible Assets with an aggregate Discounted Value equal to or
  greater than the AMPS Basic Maintenance Amount.
 
  For purposes of determining whether the Fund has Moody's Eligible Assets
with an aggregate Discounted Value that equals or exceeds the AMPS Basic
Maintenance Amount, the Discounted Value of Moody's Eligible Assets that the
Fund is obligated to deliver or receive pursuant to an outstanding futures
contract or option shall be as follows: (i) assets subject to call options
written by the Fund that are either exchange-traded and "readily reversible"
or that expire within 49 days after the date as of which such valuation is
made shall be valued at the lesser of (A) Discounted Value and (B) the
exercise price of the call option written by the Fund; (ii) assets subject to
call options written by the Fund not meeting the requirements of clause (i) of
this sentence shall have no value; (iii) assets subject to put options written
by the Fund shall be valued at the lesser of (A) the exercise price and (B)
the Discounted Value of the subject security; (iv) futures contracts shall be
valued at the lesser of (A) settlement price and (B) the Discounted Value of
the subject security, provided that, if a contract matures within 49 days
after the date as of which such valuation is made, where the Fund is the
seller the contract may be valued at the settlement price and where the Fund
is the buyer the contract may be valued at the Discounted Value of the subject
securities; and (v) where delivery may be made to the Fund with any security
of a class of securities, the Fund shall assume that it will take delivery of
the security with the lowest Discounted Value.
 
  For purposes of determining whether the Fund has Moody's Eligible Assets
with an aggregate Discounted Value that equals or exceeds the AMPS Basic
Maintenance Amount, the following amounts shall be subtracted from the
aggregate Discounted Value of the Moody's Eligible Assets held by the Fund:
10% of the exercise price of a written call option; (ii) the exercise price of
any written put option; (iii) where the Fund is the seller under a financial
futures contract, 10% of the settlement price of the financial futures
contract; (iv) where the Fund is the purchaser under a financial futures
contract, the settlement price of assets purchased under such financial
futures contract; (v) the settlement price of the underlying financial futures
contract if the Fund writes put options on a financial futures contract; and
(vi) 105% of the fair market value of the underlying financial futures
contracts if the Fund writes call options on a financial futures contract and
does not own the underlying contract.
 
  For so long as any shares of AMPS are rated by Moody's, the Fund will not
enter into any contract to purchase securities for a fixed price at a future
date beyond customary settlement time (other than such contracts that
constitute Moody's Hedging Transactions), except that the Fund may enter into
such contracts to purchase newly-issued securities on the date such securities
are issued ("Forward Commitments"), subject to the following limitations:
 
    (i) the Fund will maintain in a segregated account with its custodian
  cash, cash equivalents or short term, fixed-income securities rated P-1,
  MIG-1 or VMIG-1 by Moody's and maturing prior to the date of the Forward
  Commitment with a fair market value that equals or exceeds the amount of
  the Fund's obligations under any Forward Commitments to which it is from
  time to time a party or long-term, fixed income securities with a
  Discounted Value that equals or exceeds the amount of the Fund's
  obligations under any Forward Commitment to which it is from time to time a
  party, and
 
                                      24
<PAGE>
 
    (ii) the Fund will not enter into a Forward Commitment unless, after
  giving effect thereto, the Fund would continue to have Moody's Eligible
  Assets with an aggregate Discounted Value equal to or greater than the AMPS
  Basic Maintenance Amount.
 
  For purposes of determining whether the Fund has Moody's Eligible Assets
with an aggregate Discounted Value that equals or exceeds the AMPS Basic
Maintenance Amount, the Discounted Value of all Forward Commitments to which
the Fund is a party and of all securities deliverable to the Fund pursuant to
such Forward Commitments shall be zero.
 
  For so long as AMPS are rated by S&P or Moody's, the Fund, unless it has
received written confirmation from S&P and/or Moody's, as the case may be,
that such action would not impair the ratings then assigned to the AMPS by S&P
and/or Moody's, as the case may be, will not (i) borrow money except for the
purpose of clearing transactions in portfolio securities (which borrowings
under any circumstances shall be limited to the lesser of $10 million and an
amount equal to 5% of the fair market value of the Fund's assets at the time
of such borrowings and which borrowings shall be repaid within 60 days and not
be extended or renewed and shall not cause the aggregate Discounted Value of
Moody's Eligible Assets and S&P Eligible Assets to be less than the AMPS Basic
Maintenance Amount), (ii) engage in short sales of securities, (iii) lend any
securities, (iv) issue any class or series of shares ranking prior to or on a
parity with the AMPS with respect to the payment of dividends or the
distribution of assets upon dissolution, liquidation or winding up of the
Fund, (v) reissue any AMPS previously purchased or redeemed by the Fund, (vi)
merge or consolidate into or with any other corporation or entity, (vii)
change the Fund's pricing service or (viii) engage in reverse repurchase
agreements.

COMPENSATION OF TRUSTEES
 
  Pursuant to an Investment Advisory Agreement with the Fund, the Investment
Adviser pays all compensation of officers and employees of the Fund as well as
the fees of all Trustees who are affiliated persons of ML & Co. or its
subsidiaries.
 
  The Fund pays each Trustee not affiliated with the Investment Adviser (each
a "non-affiliated Trustee") a fee of $2,000 per year plus $200 per meeting
attended, and pays all Trustees' out-of-pocket expenses relating to attendance
at meetings. The Fund also pays members of the Board's audit and nominating
committee (the
 
                                      26
<PAGE>
 
"Committee"), which consists of all the non-affiliated Trustees, an annual fee
of $800. The Chairman of the Committee receives an additional annual fee of
$1,000.
 
  The following table sets forth compensation to be paid by the Fund to the
non-affiliated Trustees projected through the end of the Fund's first full

(1) The Trustees serve on the boards of MLAM/FAM Advised Funds as follows: Mr.
    Forbes (35 registered investment companies consisting of 48 portfolios);
    Ms. Montgomery (35 registered investment companies consisting of 48
    portfolios); Mr. Reilly (54 registered investment companies consisting of
    67 portfolios); Mr. Ryan (35 registered investment companies consisting of
    46 portfolios); and Mr. West (56 registered investment companies
    consisting of 81 portfolios).
 
                INVESTMENT ADVISORY AND MANAGEMENT ARRANGEMENTS
 
  The Fund has entered into an Investment Advisory Agreement with the
Investment Adviser. The Fund pays the Investment Adviser a monthly fee at an
annual rate of 0.55 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).
 
  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-interested 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.
 
  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
 
                                      27
<PAGE>
 
are selling the same security. If purchases or sales of securities by the
Investment Adviser for the Fund or other funds for which it acts as investment
adviser or for other advisory clients arise for consideration at or about the
same time, transactions in such securities will be made, insofar as feasible,
for the respective funds and clients in a manner deemed equitable to all.
Transactions effected by the Investment Adviser (or its affiliates) on behalf
of more than one of its clients during the same period may increase the demand
for securities being purchased or the supply of securities being sold, causing
an adverse effect on price.
 
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.
 
  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 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 service performed by the Investment Adviser and the expenses of the
Investment Adviser will not necessarily 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 the
Underwriter in high quality, short-term, tax-exempt securities. See
"Investment Restrictions." However, affiliated persons of the Fund, including
Merrill Lynch, may serve as its brokers in certain over-the-counter
transactions conducted on an agency basis.
 
                                      28
<PAGE>
 
  The Fund also may purchase tax-exempt debt instruments in individually
negotiated transactions with the issuer. 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, 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 has certain tax consequences and
results in greater transaction costs, which are borne directly by the Fund.
 
                                     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 Internal Revenue Service (the "IRS"), in a revenue ruling, held that
certain auction rate preferred stock would be treated as stock for Federal
income tax purposes. The terms of the AMPS are substantially similar, but not
identical, to the auction rate preferred stock discussed in the revenue
ruling, and in the opinion of Brown & Wood LLP, counsel to the Fund, the AMPS
will constitute stock of the Fund and distributions with respect to AMPS
(other than distributions in redemption of AMPS subject to Section 302(b) of
the Code) will constitute dividends to the extent of the Fund's current and
accumulated earnings and profits as calculated for Federal income tax
purposes. Nevertheless, it is possible that the IRS might take a contrary
position, asserting, for example, that the AMPS constitute debt of the Fund.
If this position were upheld, the discussion of the treatment of distributions
below would not apply. Instead, distributions by the Fund to holders of AMPS
would constitute interest, whether or not they exceeded the earnings and
profits of the Fund, would be included in full in the income of the recipient
and would be taxed as ordinary income. Counsel believes that such a position,
if asserted by the IRS, would be unlikely to prevail.
 
  The Fund 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 which
are attributable to interest on tax-exempt obligations and designated by the
Fund as exempt-
 
                                      29
<PAGE>
 
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 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
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 are
considered 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
 
                                      30
<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-interest 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 which 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 IRS has taken the position in a revenue ruling that if a RIC has two or
more classes of shares, it may designate distributions made to each class in
any year as consisting of no more than such class's proportionate share of
particular types of income, including exempt interest and net long-term
capital gains. A class's proportionate share of a particular type of income is
determined according to the percentage of total dividends paid by the RIC
during such year that was paid to such class. Thus, the Fund is required to
allocate a portion of its net capital gains and other taxable income to the
AMPS of each series. The Fund generally will notify the Auction Agent of the
amount of any net capital gains and other taxable income to be included in any
dividend on AMPS prior to the Auction establishing the Applicable Rate for
such dividend. Except for the portion of any dividend that it informs the
Auction Agent will be treated as capital gains or other taxable income, the
Fund anticipates that the dividends paid on the AMPS will constitute exempt-
interest dividends. The amount of net capital gains and ordinary income
allocable to AMPS (the "taxable distribution") will depend upon the amount of
such gains and income realized by the Fund and the total dividends paid by the
Fund on common shares and shares of the two series of AMPS during a taxable
year, but the taxable distribution generally is not expected to be
significant.
 
  In the opinion of Brown & Wood LLP, counsel to the Fund, under current law
the manner in which the Fund intends to allocate items of tax-exempt income,
net capital gains and other taxable income, if any, among common shares and
shares of the two series of AMPS will be respected for Federal income tax
purposes. However, the tax treatment of Additional Dividends may affect the
Fund's calculation of each class' allocable share of capital gains and other
taxable income. See "Tax Treatment of Additional Dividends." In addition,
there is currently no direct guidance from the IRS or other sources
specifically addressing whether the Fund's method for allocating tax-exempt
income, net capital gains and other taxable income among common shares and
shares of the two series of AMPS will be respected for Federal income tax
purposes, and it is possible that the IRS could disagree with counsel's
opinion and attempt to reallocate the Fund's net capital gains or other
taxable income. In the event of a reallocation, some of the dividends
identified by the Fund as exempt-interest dividends to holders of AMPS may be
recharacterized as additional capital gains or other taxable income. In the
event of such recharacterization, the Fund would not be required to make
payments to such shareholders to offset the tax effect of such reallocation.
In addition, a reallocation may cause the Fund to be liable for income tax and
excise tax on any reallocated taxable income. Brown & Wood LLP has advised the
Fund that, in its opinion, if the IRS were to challenge in court the Fund's
allocations of income and gain, the IRS would be unlikely to prevail. A holder
should be aware, however, that the opinion of Brown & Wood LLP represents only
its best legal judgment and is not binding on the IRS or the courts.
 
                                      31
<PAGE>
 
  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 "private activity bonds" issued after August 7,
1986. Private activity bonds are bonds which, although tax-exempt, are used
for purposes other than those generally performed by governmental units and
which benefit non-governmental entities (e.g., bonds used for industrial
development or housing purposes). Income received on such bonds is classified
as an item of "tax preference" which could subject certain investors in such
bonds, including shareholders of the Fund, to an 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 which constitutes an item of tax preference
for alternative minimum tax purposes. The Code further provides that
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 AMPS are outstanding the Fund does not meet the asset
coverage requirements of the 1940 Act, the Fund will be required to suspend
distributions to holders of common shares until the asset coverage is
restored. See "Description of AMPS--Dividends--Restrictions on Dividends and
Other Payments." This may prevent the Fund from distributing at least 90% of
its net income, and may, therefore, jeopardize the Fund's qualification for
taxation as a RIC. Upon any failure to meet the asset coverage requirements of
the 1940 Act, the Fund, in its sole discretion, may, and under certain
circumstances will be required to, redeem shares of AMPS in order to maintain
or restore the requisite asset coverage and avoid the adverse consequences to
the Fund and its shareholders of failing to qualify as a RIC. See "Description
of AMPS--Redemption." 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 IRS 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 IRS would agree that dividends on the
preferred shares are not preferential. If the IRS successfully disallowed the
dividends paid deduction for dividends on the preferred shares, the Fund could
lose the benefit of the special treatment afforded RICs under the Code. In
this case, dividends paid by the Fund would not be exempt from Federal income
taxes. Additionally, the Fund would be subject to the alternative minimum tax.
 
  Under certain Code provisions, some taxpayers may be subject to a 31%
withholding tax on certain ordinary income dividends and on capital gain
dividends and redemption payments ("backup withholding"). Generally,
shareholders subject to backup withholding will be those for whom no certified
taxpayer identification number is on file with the Fund or who, to the Fund's
knowledge, have furnished an incorrect number. When establishing an account,
an investor must certify under penalty of perjury that such number is correct
and that such investor is not otherwise subject to backup withholding.
 
  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 individuals and entities
unless a reduced rate of withholding or a withholding exemption is provided
under
 
                                      32
<PAGE>
 
applicable treaty law. Nonresident shareholders are urged to consult their own
tax advisers concerning the applicability of the United States withholding
tax.
 
  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 ADDITIONAL DIVIDENDS
 
  If the Fund makes a Retroactive Taxable Allocation, it will pay Additional
Dividends to holders of AMPS who are subject to the Retroactive Taxable
Allocation. See "Description of AMPS--Dividends--Additional Dividends" in the
prospectus. The Federal income tax consequences of Additional Dividends under
existing law are uncertain. The Fund intends to treat a holder as receiving a
dividend distribution in the amount of any Additional Dividend only as and
when such Additional Dividend is paid. An Additional Dividend generally will
be designated by the Fund as an exempt-interest divided except as otherwise
required by applicable law. However, the IRS may assert that all or part of an
Additional Dividend is a taxable dividend either in the taxable year for which
the Retroactive Taxable Allocation is made or in the taxable year in which the
Additional Dividend is paid.
 
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.
 
                               ----------------
 
  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, foreign, state or local taxes.
 
                                NET ASSET VALUE
 
  Net asset value per common share is determined as of 15 minutes after the
close of business on the New York Stock Exchange (the "NYSE") (generally, the
NYSE closes at 4:00 p.m. Eastern time) on the last Business Day of 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 AMPS
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

             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 common
shares for $100,005 on January  , 1999. The General Partner of the Investment
Adviser is an indirect 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 (start of the Fund's new fiscal year) will be charged
to expense at that date. At the present time, management believes this charge
will not have any material impact to 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 for advisory services, at an annual rate equal to 0.55 of 1% of
the average weekly net assets of the Fund, 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   % 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

                   NOTES TO FINANCIAL STATEMENTS (UNAUDITED)
 
1. SIGNIFICANT ACCOUNTING POLICIES:
 
  MuniHoldings Florida Insured Fund IV (the "Fund") is registered under the
Investment Company Act of 1940 as a non-diversified, closed-end management
investment company. Prior to commencement of operations on January  , 1999 the
Fund had no operations other than those relating to organizational matters and
the sale of 6,667 common shares on January  , 1999, to Fund Asset Management,
L.P. for $100,005. The Fund determines and makes available for publication the
net asset value of its common shares on a weekly basis. The Fund's common
shares are listed on the New York Stock Exchange under the symbol MFR. The
following is a summary of significant accounting policies followed by the
Fund.
 
  (a) Valuation of investments--Municipal bonds are traded primarily in the
over-the-counter markets and are valued at the most recent bid price or yield
equivalent as obtained by the Fund's pricing service from dealers that make
markets in such securities. Financial futures contracts and options thereon,
which are traded on exchanges, are valued at their closing prices as of the
close of such exchanges. Options, which are traded on exchanges, are valued at
their last sale price as of the close of such exchanges or, lacking any sales,
at the last available bid price. Securities with remaining maturities of sixty
days or less are valued at amortized cost, which approximates market value.
Securities and assets for which market quotations are not readily available
are valued at fair value as determined in good faith by or under the direction
of the Board of Trustees of the Fund, including valuations furnished by a
pricing service retained by the Fund, which may utilize a matrix system for
valuations. The procedures of the pricing service and its valuations are
reviewed by the officers of the Fund under the general supervision of the
Board of Trustees.
 
  (b) Derivative financial instruments--The Fund may engage in various
portfolio strategies to seek to increase its return by hedging its portfolio
against adverse movements in the debt markets. Losses may arise due to changes
in the value of the contract or if the counterparty does not perform under the
contract.
 
  . Financial futures contracts--The Fund may purchase or sell financial
    futures contracts and options on such futures contracts for the purpose
    of hedging the market risk on existing securities or the intended
    purchase of securities. Futures contracts are contracts for delayed
    delivery of securities at a specific future date and at a specific price
    or yield. Upon entering into a contract, the Fund deposits and maintains
    as collateral such initial margin as required by the exchange on which
    the transaction is effected. Pursuant to the contract, the Fund agrees to
    receive from or pay to the broker an amount of cash equal to the daily
    fluctuation in value of the contract. Such receipts or payments are known
    as variation margin and are recorded by the Fund as unrealized gains or
    losses. When the contract is closed, the Fund records a realized gain or
    loss equal to the difference between the value of the contract at the
    time it was opened and the value at the time it was closed.
 
  . Options--The Fund is authorized to write covered call options and
    purchase call and put options. When the Fund writes an option, an amount
    equal to the premium received by the Fund is reflected as an asset and an
    equivalent liability. The amount of the liability is subsequently marked
    to market to reflect the current market value of the option written. When
    a security is purchased or sold through an exercise of an option, the
    related premium paid (or received) is added to (or deducted from) the
    basis of the security acquired or deducted from (or added to) the
    proceeds of the security sold. When an option expires (or the Fund enters
    into a closing transaction), the Fund realizes a gain or loss on the
    option to the extent of the premiums received or paid (or gain or loss to
    the extent the cost of the closing transaction exceeds the premium paid
    or received).
 
  Written and purchased options are non-income producing investments.
 
  (c) Income taxes--It is the Fund's policy to comply with the requirements of
the Internal Revenue Code applicable to regulated investment companies and to
distribute substantially all of its taxable income to its shareholders.
Therefore, no Federal income tax provision is required.

            NOTES TO FINANCIAL STATEMENTS (UNAUDITED)--(CONTINUED)
 
 
  (d) Security transactions and investment income--Security transactions are
recorded on the dates the transactions are entered into (the trade dates).
Interest income is recognized on the accrual basis. Discounts and market
premiums are amortized into interest income. Realized gains and losses on
security transactions are determined on the identified cost basis.
 
  (e) Deferred organization and offering expenses--Deferred organization
expenses are amortized on a straight-line basis over a period not exceeding
five years. In accordance with Statement of Position 98-5, any unamortized
organization expenses will be expensed on the first day of the next fiscal
year beginning after December 15, 1998. This charge will not have any material
impact on the operations of the Fund. Direct expenses relating to the public
offering of the Fund's common shares were charged to capital at the time of
issuance of the shares.
 
  (f) Dividends and distributions--Dividends from net investment income are
declared and paid monthly. Distributions of capital gains are recorded on the
ex-dividend dates.
 
2. INVESTMENT ADVISORY AGREEMENT AND TRANSACTIONS WITH AFFILIATES:
 
  The Fund has entered into an Investment Advisory Agreement with Fund Asset
Management, L.P. ("FAM"). The general partner of FAM is Princeton Services,
Inc. ("PSI"), an indirect wholly-owned subsidiary of Merrill Lynch & Co., Inc.
("ML & Co."), which is the limited partner.
 
  FAM is responsible for the management of the Fund's portfolio and provides
the necessary personnel, facilities, equipment and certain other services
necessary to the operations of the Fund. For such services, the Fund pays a
monthly fee at an annual rate of 0.55% of the Fund's average weekly net
assets, including proceeds from the issuance of preferred shares. For the
period ended       1999, FAM earned fees of $    , all of which was
voluntarily waived. FAM also reimbursed the Fund additional expenses of $    .
 
  Accounting services are provided to the Fund by FAM at cost.
 
  Certain officers and/or Trustees of the Fund are officers and/or directors
of FAM, PSI, and/or ML & Co.
 
3. INVESTMENTS:
 
  Purchases of investments, excluding short-term securities, for the period
ended       , 1999 were $   . There were no long-term sales.

4. CAPITAL SHARE TRANSACTIONS:
 
  The Fund is authorized to issue an unlimited number of shares of beneficial
interest, including preferred shares, par value $.10 per share, all of which
were initially classified as common shares. The Board of Trustees is
authorized, however, to reclassify any unissued shares of capital without
approval of holders of common shares.
 
  Shares issued and outstanding increased by      as a result of the initial
offering during the period ended       , 1999.
 
5. GENERAL:
 
  As of       , 1999, the Fund had only    days of investment operations and
had not yet declared dividends (whereas it will ordinarily do so on a monthly
basis). As a result, the Fund believes that more extensive interim financial
statements would not be indicative of the Fund's current and ongoing
operations. The Fund believes that such financial statements may be misleading
to potential investors and, accordingly, believes that inclusion of such
financial statements would be inappropriate. For the period ended       ,
1999, the Fund had net investment income of $   . FAM voluntarily waived all
expenses.

                                  APPENDIX A
 
                   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
 
                                      A-1
<PAGE>
 
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 in State personal income over the most recent twenty quarters times the

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 considerably less damage than in 1992 and 1995. During the
1998 hurricane season, which ended November 30, two hurricanes 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 the
fiscal year ended 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: These 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,
Al, Baal, Bal 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-l repayment capacity
will often be evidenced by the following characteristics: leading market
positions in well established industries; high rates of return on funds
employed; conservative capitalization structures with moderate reliance on
debt and ample asset protection; broad margins in earning coverage of fixed
financial charges and high internal cash generation; and with 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, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be
more affected by external conditions. Ample alternate liquidity is maintained.
 
  Issuers rated Prime-3 (or supporting institutions) have an acceptable
ability for repayment of 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 the requirement for relatively high
financial leverage. Adequate alternate liquidity is maintained.
 
  Issuers rated Not Prime do not fall within any of the Prime rating
categories.
 
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 assessment 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 issuer or
obtained by Standard & Poor's from other sources Standard & Poor's considers
reliable. Standard & Poor's does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information. The
ratings may be changed, suspended or withdrawn as a result of changes in, or
unavailability of, such information, or based on other circumstances.
 
  The ratings are based, in varying degrees, on the following considerations:
 
    I. Likelihood of default--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 of the obligor 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.
 
                                      B-2
<PAGE>
 
  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 characteristics, C 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-l"
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 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 such 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.
 
                                      B-3
<PAGE>
 
  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.
 
  Bonds that have 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.
 
                                      B-4
<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 "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 three to 12 months.
 
Ratings       An outlook is used to describe the most likely direction of any
Outlook       rating change over thentermediate 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.
 
                                      B-5
<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.

                              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 its 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 aversely affected by either of the above described events. In
addition to the payment of premium, 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 Fund will seek to utilize insurance companies that 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 ("Moody's"). There
can be no assurance however, that insurance from insurance carriers meeting
these criteria will be at all times available.
 
  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.
Capacity to honor insurance contracts is considered by S&P to be extremely
strong and highly likely to remain so over a long period of time. 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
liquidity are all at very secure levels and are unlikely to be affected by
potential adverse underwriting, investment or cyclical events. 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.
 
  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
 
                                      C-1
<PAGE>
 
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.

                             SETTLEMENT PROCEDURES
 
  The following summary of Settlement Procedures sets forth the procedures
expected to be followed in connection with the settlement of each Auction and
will be incorporated by reference in the Auction Agent Agreement and each
Broker-Dealer Agreement. Nothing contained in this Appendix D constitutes a
representation by the Fund that in each Auction each party referred to herein
actually will perform the procedures described herein to be performed by such
party. Capitalized terms used herein shall have the respective meanings
specified in the glossary of this Prospectus or Appendix E hereto, as the case
may be.
 
  (a) On each Auction Date, the Auction Agent shall notify by telephone or
through the Auction Agent's Processing System the Broker-Dealers that
participated in the Auction held on such Auction Date and submitted an Order
on behalf of any Beneficial Owner or Potential Beneficial Owner of:
 
    (i) the Applicable Rate fixed for the next succeeding Dividend Period;
 
    (ii) whether Sufficient Clearing Bids existed for the determination of
  the Applicable Rate;
 
    (iii) if such Broker-Dealer (a "Seller's Broker-Dealer") submitted a Bid
  or a Sell Order on behalf of a Beneficial Owner, the number, if any, of
  AMPS to be sold by such Beneficial Owner;

  behalf of a Potential Beneficial Owner, the number, if any, of AMPS to be
  purchased by such Potential Beneficial Owner;
 
    (v) if the aggregate number of AMPS to be sold by all Beneficial Owners
  on whose behalf such Broker-Dealer submitted a Bid or a Sell Order exceeds
  the aggregate number of AMPS to be purchased by all Potential Beneficial
  Owners on whose behalf such Broker-Dealer submitted a Bid, the name or
  names of one or more Buyer's Broker-Dealers (and the name of the Agent
  Member, if any, of each such Buyer's Broker-Dealer) acting for one or more
  purchasers of such excess number of AMPS and the number of such shares to
  be purchased from one or more Beneficial Owners on whose behalf such
  Broker-Dealer acted by one or more Potential Beneficial Owners on whose
  behalf each of such Buyer's Broker-Dealers acted;
 
    (vi) if the aggregate number of AMPS to be purchased by all Potential
  Beneficial Owners on whose behalf such Broker-Dealer submitted a Bid
  exceeds the aggregate number of AMPS to be sold by all Beneficial Owners on
  whose behalf such Broker-Dealer submitted a Bid or a Sell Order, the name
  or names of one or more Seller's Broker-Dealers (and the name of the Agent
  Member, if any, of each such Seller's Broker-Dealer) acting for one or more
  sellers of such excess number of AMPS and the number of such shares to be
  sold to one or more Potential Beneficial Owners on whose behalf such
  Broker-Dealer acted by one or more Beneficial Owners on whose behalf each
  of such Seller's Broker-Dealers acted; and
 
    (vii) the Auction Date of the next succeeding Auction with respect to the
  AMPS.
 
  (b) On each Auction Date, each Broker-Dealer that submitted an Order on
behalf of any Beneficial Owner or Potential Beneficial Owner shall:
 
    (i) in the case of a Broker-Dealer that is a Buyer's Broker-Dealer,
  instruct each Potential Beneficial Owner on whose behalf such Broker-Dealer
  submitted a Bid that was accepted, in whole or in part, to instruct such
  Potential Beneficial Owner's Agent Member to pay to such Broker-Dealer (or
  its Agent Member) through the Securities Depository the amount necessary to
  purchase the number of AMPS to be purchased pursuant to such Bid against
  receipt of such shares and advise such Potential Beneficial Owner of the
  Applicable Rate for the next succeeding Dividend Period;
 
    (ii) in the case of a Broker-Dealer that is a Seller's Broker-Dealer,
  instruct each Beneficial Owner on whose behalf such Broker-Dealer submitted
  a Sell Order that was accepted, in whole or in part, or a Bid that was
  accepted, in whole or in part, to instruct such Beneficial Owner's Agent
  Member to deliver to such Broker-Dealer (or its Agent Member) through the
  Securities Depository the number of AMPS to be sold pursuant to such Order
  against payment therefor and advise any such Beneficial Owner that will
  continue to hold AMPS of the Applicable Rate for the next succeeding
  Dividend Period;
 
                                      D-1
<PAGE>
 
    (iii) advise each Beneficial Owner on whose behalf such Broker-Dealer
  submitted a Hold Order of the Applicable Rate for the next succeeding
  Dividend Period;
 
    (iv) advise each Beneficial Owner on whose behalf such Broker-Dealer
  submitted an Order of the Auction Date for the next succeeding Auction; and
 
    (v) advise each Potential Beneficial Owner on whose behalf such Broker-
  Dealer submitted a Bid that was accepted, in whole or in part, of the
  Auction Date for the next succeeding Auction.
 
  (c) On the basis of the information provided to it pursuant to (a) above,
each Broker-Dealer that submitted a Bid or a Sell Order on behalf of a
Potential Beneficial Owner or a Beneficial Owner shall, in such manner and at
such time or times as in its sole discretion it may determine, allocate any
funds received by it pursuant to (b)(i) above and any AMPS received by it
pursuant to (b)(ii) above among the Potential Beneficial Owners, if any, on
whose behalf such Broker-Dealer submitted Bids, the Beneficial Owners, if any,
on whose behalf such Broker-Dealer submitted Bids that were accepted or Sell
Orders, and any Broker-Dealer or Broker-Dealers identified to it by the
Auction Agent pursuant to (a)(v) or (a)(vi) above.
 
  (d) On each Auction Date:
 
    (i) each Potential Beneficial Owner and Beneficial Owner shall instruct
  its Agent Member as provided in (b)(i) or (ii) above, as the case may be;
 
    (ii) each Seller's Broker-Dealer which is not an Agent Member of the
  Securities Depository shall instruct its Agent Member to (A) pay through
  the Securities Depository to the Agent Member of the Beneficial Owner
  delivering shares to such Broker-Dealer pursuant to (b)(ii) above the
  amount necessary to purchase such shares against receipt of such shares,
  and (B) deliver such shares through the Securities Depository to a Buyer's
  Broker-Dealer (or its Agent Member) identified to such Seller's Broker-
  Dealer pursuant to (a)(v) above against payment therefor; and
 
    (iii) each Buyer's Broker-Dealer which is not an Agent Member of the
  Securities Depository shall instruct its Agent Member to (A) pay through
  the Securities Depository to a Seller's Broker-Dealer (or its Agent Member)
  identified pursuant to (a)(vi) above the amount necessary to purchase the
  shares to be purchased pursuant to (b)(i) above against receipt of such
  shares, and (B) deliver such shares through the Securities Depository to
  the Agent Member of the purchaser thereof against payment therefor.
 
  (e) On the day after the Auction Date:
 
    (i) each Bidder's Agent Member referred to in (d)(i) above shall instruct
  the Securities Depository to execute the transactions described in (b)(i)
  or (ii) above, and the Securities Depository shall execute such
  transactions;
 
    (ii) each Seller's Broker-Dealer or its Agent Member shall instruct the
  Securities Depository to execute the transactions described in (d)(ii)
  above, and the Securities Depository shall execute such transactions; and
 
    (iii) each Buyer's Broker-Dealer or its Agent Member shall instruct the
  Securities Depository to execute the transactions described in (d)(iii)
  above, and the Securities Depository shall execute such transactions.
 
    (f) If a Beneficial Owner selling AMPS in an Auction fails to deliver
  such shares (by authorized book-entry), a Broker-Dealer may deliver to the
  Potential Beneficial Owner on behalf of which it submitted a Bid that was
  accepted a number of whole AMPS that is less than the number of shares that
  otherwise was to be purchased by such Potential Beneficial Owner. In such
  event, the number of AMPS to be so delivered shall be determined solely by
  such Broker-Dealer. Delivery of such lesser number of shares shall
  constitute good delivery. Notwithstanding the foregoing terms of this
  paragraph (f), any delivery or non-delivery of shares which shall represent
  any departure from the results of an Auction, as determined by the Auction
  Agent, shall be of no effect unless and until the Auction Agent shall have
  been notified of such delivery or non-delivery in accordance with the
  provisions of the Auction Agent Agreement and the Broker-Dealer Agreements.

  The following procedures will be set forth in provisions of the Certificate
of Designation relating to the AMPS, and will be incorporated by reference in
the Auction Agent Agreement and each Broker-Dealer Agreement. The terms not
defined below are defined in the forepart of this Prospectus. Nothing

each Auction each party referred to herein actually will perform the
procedures described herein to be performed by such party.
 
PARAGRAPH 10(A) CERTAIN DEFINITIONS.
 
  As used in this Paragraph 10, the following terms shall have the following
meanings, unless the context otherwise requires:
 
    (i) "AMPS" shall mean the shares of AMPS being auctioned pursuant to this
  Paragraph 10.
 
    (ii) "Auction Date" shall mean the first Business Day preceding the first
  day of a Dividend Period.

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

  The Fund shall take all reasonable action necessary to enable S&P and
Moody's to provide a rating for the AMPS. If either S&P or Moody's shall not
make such a rating available, or if neither S&P nor Moody's shall make such a
rating available, Merrill Lynch, Pierce, Fenner & Smith Incorporated or its
affiliates and successors, after consultation with the Fund, shall select a
nationally recognized statistical rating organization or two nationally
recognized statistical rating organizations to act as a Substitute Rating
Agency or Substitute Rating Agencies, as the case may be.

  below.
 
    (ix) "Sell Order" shall have the meaning specified in Paragraph 10(b)(i)
  below.
 
    (x) "Submission Deadline" shall mean 1:00 p.m., Eastern time, on any
  Auction Date or such other time on any Auction Date as may be specified by
  the Auction Agent from time to time as the time by which each Broker-Dealer
  must submit to the Auction Agent in writing all Orders obtained by it for
  the Auction to be conducted on such Auction Date.

  Paragraph 10(d)(i) below.
 
    (xvi) (xvi) "Winning Bid Rate" shall have the meaning specified in
  Paragraph 10(d)(i) below.
 
PARAGRAPH 10(B) ORDERS BY BENEFICIAL OWNERS, POTENTIAL BENEFICIAL OWNERS,
EXISTING HOLDERS AND POTENTIAL HOLDERS.
 
  (i) Unless otherwise permitted by the Fund, Beneficial Owners and Potential
Beneficial Owners may only participate in Auctions through their Broker-
Dealers. Broker-Dealers will submit the Orders of their respective customers
who are Beneficial Owners and Potential Beneficial Owners to the Auction
Agent, designating themselves as Existing Holders in respect of shares subject
to Orders submitted or deemed submitted to them by Beneficial Owners and as
Potential Holders in respect of shares subject to Orders submitted to them by
Potential Beneficial Owners. A Broker-Dealer may also hold AMPS in its own
account as a Beneficial Owner. A Broker-Dealer may thus submit Orders to the
Auction Agent as a Beneficial Owner or a Potential Beneficial Owner and
therefore participate in an Auction as an Existing Holder or Potential Holder
on behalf of both itself and its customers. On or prior to the Submission
Deadline on each Auction Date:
 
    (A) each Beneficial Owner may submit to its Broker-Dealer information as
  to:
 
      (1) the number of outstanding AMPS, if any, held by such Beneficial
    Owner which such Beneficial Owner desires to continue to hold without
    regard to the Applicable Rate for the next succeeding Dividend Period;
 
      (2) the number of outstanding AMPS, if any, held by such Beneficial
    Owner which such Beneficial Owner desires to continue to hold, provided
    that the Applicable Rate for the next succeeding Dividend Period shall
    not be less than the rate per annum specified by such Beneficial Owner,
    and/or
 
      (3) the number of outstanding AMPS, if any, held by such Beneficial
    Owner which such Beneficial Owner offers to sell without regard to the
    Applicable Rate for the next succeeding Dividend Period; and
 
    (B) each Broker-Dealer, using a list of Potential Beneficial Owners that
  shall be maintained in good faith for the purpose of conducting a
  competitive Auction, shall contact Potential Beneficial Owners, including
  Persons that are not Beneficial Owners, on such list to determine the
  number of outstanding AMPS, if any, which each such Potential Beneficial
  Owner offers to purchase, provided that the Applicable Rate for the next
  succeeding Dividend Period shall not be less than the rate per annum
  specified by such Potential Beneficial Owner.
 
  For the purposes hereof, the communication by a Beneficial Owner or
Potential Beneficial Owner to a Broker-Dealer, or the communication by a
Broker-Dealer acting for its own account to the Auction Agent, of information
referred to in clause (A) or (B) of this Paragraph 10(b)(i) is hereinafter
referred to as an "Order" and each Beneficial Owner and each Potential
Beneficial Owner placing an Order, including a Broker-Dealer acting in such
capacity for its own account, is hereinafter referred to as a "Bidder"; an
Order containing the information referred to in clause (A)(1) of this
Paragraph 10(b)(i) is hereinafter referred to as a "Hold Order"; an Order
containing the information referred to in clause (A)(2) or (B) of this
Paragraph 10(b)(i) is hereinafter referred to as a "Bid"; and an Order
containing the information referred to in clause (A)(3) of this Paragraph
10(b)(i) is hereinafter referred to as a "Sell Order." Inasmuch as a Broker-
Dealer participates in an Auction as an Existing Holder or a Potential Holder
only to represent the interests of a Beneficial Owner or Potential Beneficial
Owner, whether it be its customers or itself, all discussion herein relating
to the consequences of an Auction for Existing Holders and Potential Holders
also applies to the underlying beneficial ownership interests represented.
 
                                      E-2
<PAGE>
 
  (ii) (A) A Bid by an Existing Holder shall constitute an irrevocable offer
to sell:
 
    (1) the number of outstanding AMPS specified in such Bid if the
  Applicable Rate determined on such Auction Date shall be less than the rate
  per annum specified in such Bid; or
 
    (2) such number or a lesser number of outstanding AMPS to be determined
  as set forth in Paragraph 10(e)(i)(D) if the Applicable Rate determined on
  such Auction Date shall be equal to the rate per annum specified therein;
  or
 
    (3) a lesser number of outstanding AMPS to be determined as set forth in
  Paragraph 10(e)(ii)(C) if such specified rate per annum shall be higher
  than the Maximum Applicable Rate and Sufficient Clearing Bids do not exist.
 
  (B) A Sell Order by an Existing Holder shall constitute an irrevocable offer
to sell:
 
    (1) the number of outstanding AMPS specified in such Sell Order, or
 
    (2) such number or a lesser number of outstanding AMPS to be determined
  as set forth in Paragraph 10(e)(ii)(C) if Sufficient Clearing Bids do not
  exist.
 
  (C) A Bid by a Potential Holder shall constitute an irrevocable offer to
purchase:
 
    (1) the number of outstanding AMPS specified in such Bid if the
  Applicable Rate determined on such Auction Date shall be higher than the
  rate per annum specified in such Bid; or
 
    (2) such number or a lesser number of outstanding AMPS to be determined
  as set forth in Paragraph 10(e)(i)(E) if the Applicable Rate determined on
  such Auction Date shall be equal to the rate per annum specified therein.
 
PARAGRAPH 10(C) SUBMISSION OF ORDERS BY BROKER-DEALERS TO AUCTION AGENT.
 
  (i) Each Broker-Dealer shall submit in writing or through the Auction
Agent's Auction Processing System to the Auction Agent prior to the Submission
Deadline on each Auction Date all Orders obtained by such Broker-Dealer,
designating itself (unless otherwise permitted by the Fund) as an Existing
Holder in respect of shares subject to Orders submitted or deemed submitted to
it by Beneficial Owners and as a Potential Holder in respect of shares subject
to Orders submitted to it by Potential Beneficial Owners, and specifying with
respect to each Order:
 
    (A) the name of the Bidder placing such Order (which shall be the
    Broker-Dealer unless otherwise permitted by the Fund);
 
    (B) the aggregate number of outstanding AMPS that are the subject of
    such Order;
 
    (C) to the extent that such Bidder is an Existing Holder
 
      (1) the number of outstanding AMPS, if any, subject to any Hold Order
    placed by such Existing Holder;
 
      (2) the number of outstanding AMPS, if any, subject to any Bid placed
    by such Existing Holder and the rate per annum specified in such Bid;
    and
 
      (3) the number of outstanding AMPS, if any, subject to any Sell Order
    placed by such Existing Holder; and
 
    (D) to the extent such Bidder is a Potential Holder, the rate per annum
    specified in such Potential Holder's Bid.
 
  (ii) If any rate per annum specified in any Bid contains more than three
figures to the right of the decimal point, the Auction Agent shall round such
rate up to the next highest one-thousandth (.001) of 1%.
 
  (iii) If an Order or Orders covering all of the outstanding AMPS held by an
Existing Holder are not submitted to the Auction Agent prior to the Submission
Deadline, the Auction Agent shall deem a Hold Order
 
                                      E-3
<PAGE>
 
(in the case of an Auction relating to a Dividend Period which is not a
Special Dividend Period of 28 days or more) and a Sell Order (in the case of
an Auction relating to a Special Dividend Period of 28 days or more) to have
been submitted on behalf of such Existing Holder covering the number of
outstanding AMPS held by such Existing Holder and not subject to Orders
submitted to the Auction Agent.
 
  (iv) If one or more Orders on behalf of an Existing Holder covering in the
aggregate more than the number of outstanding AMPS held by such Existing
Holder are submitted to the Auction Agent, such Orders shall be considered
valid as follows and in the following order of priority:
 
    (A) any Hold Order submitted on behalf of such Existing Holder shall be
  considered valid up to and including the number of outstanding AMPS held by
  such Existing Holder; provided that if more than one Hold Order is
  submitted on behalf of such Existing Holder and the number of AMPS subject
  to such Hold Orders exceeds the number of outstanding AMPS held by such
  Existing Holder, the number of AMPS subject to each of such Hold Orders
  shall be reduced pro rata so that such Hold Orders, in the aggregate, cover
  exactly the number of outstanding AMPS held by such Existing Holder;
 
    (B) any Bids submitted on behalf of such Existing Holder shall be
  considered valid, in the ascending order of their respective rates per
  annum if more than one Bid is submitted on behalf of such Existing Holder,
  up to and including the excess of the number of outstanding AMPS held by
  such Existing Holder over the number of AMPS subject to any Hold Order
  referred to in Paragraph 10(c)(iv)(A) above (and if more than one Bid
  submitted on behalf of such Existing Holder specifies the same rate per
  annum and together they cover more than the remaining number of shares that
  can be the subject of valid Bids after application of Paragraph
  10(c)(iv)(A) above and of the foregoing portion of this Paragraph
  10(c)(iv)(B) to any Bid or Bids specifying a lower rate or rates per annum,
  the number of shares subject to each of such Bids shall be reduced pro rata
  so that such Bids, in the aggregate, cover exactly such remaining number of
  shares); and the number of shares, if any, subject to Bids not valid under
  this Paragraph 10(c)(iv)(B) shall be treated as the subject of a Bid by a
  Potential Holder; and
 
    (C) any Sell Order shall be considered valid up to and including the
  excess of the number of outstanding AMPS held by such Existing Holder over
  the number of AMPS subject to Hold Orders referred to in Paragraph
  10(c)(iv)(A) and Bids referred to in Paragraph 10(c)(iv)(B); provided that
  if more than one Sell Order is submitted on behalf of any Existing Holder
  and the number of AMPS subject to such Sell Orders is greater than such
  excess, the number of AMPS subject to each of such Sell Orders shall be
  reduced pro rata so that such Sell Orders, in the aggregate, cover exactly
  the number of AMPS equal to such excess.
 
  (v) If more than one Bid is submitted on behalf of any Potential Holder,
each Bid submitted shall be a separate Bid with the rate per annum and number
of AMPS therein specified.
  (vi) Any Order submitted by a Beneficial Owner or a Potential Beneficial
Owner to its Broker-Dealer, or by a Broker-Dealer to the Auction Agent, prior
to the Submission Deadline on any Auction Date shall be irrevocable.
 
PARAGRAPH 10(D) DETERMINATION OF SUFFICIENT CLEARING BIDS, WINNING BID RATE
AND APPLICABLE RATE.
 
  (i) Not earlier than the Submission Deadline on each Auction Date, the
Auction Agent shall assemble all Orders submitted or deemed submitted to it by
the Broker-Dealers (each such Order as submitted or deemed submitted by a
Broker-Dealer being hereinafter referred to individually as a "Submitted Hold
Order," a "Submitted Bid" or a "Submitted Sell Order," as the case may be, or
as a "Submitted Order") and shall determine:
 
    (A) the excess of the total number of outstanding shares of AMPS over the
  number of outstanding AMPS that are the subject of Submitted Hold Orders
  (such excess being hereinafter referred to as the "Available AMPS");
 
                                      E-4
<PAGE>
 
    (B) from the Submitted Orders whether the number of outstanding AMPS that
  are the subject of Submitted Bids by Potential Holders specifying one or
  more rates per annum equal to or lower than the Maximum Applicable Rate
  exceeds or is equal to the sum of:
 
      (1) the number of outstanding AMPS that are the subject of Submitted
    Bids by Existing Holders specifying one or more rates per annum higher
    than the Maximum Applicable Rate, and
 
      (2) the number of outstanding AMPS that are subject to Submitted Sell
    Orders (if such excess or such equality exists (other than because the
    number of outstanding AMPS in clauses (1) and (2) above are each zero
    because all of the outstanding AMPS are the subject of Submitted Hold
    Orders), such Submitted Bids by Potential Holders hereinafter being
    referred to collectively as "Sufficient Clearing Bids"); and
 
    (C) if Sufficient Clearing Bids exist, the lowest rate per annum
  specified in the Submitted Bids (the "Winning Bid Rate") that if:
 
      (1) each Submitted Bid from Existing Holders specifying the Winning
    Bid Rate and all other submitted Bids from Existing Holders specifying
    lower rates per annum were rejected, thus entitling such Existing
    Holders to continue to hold the AMPS that are the subject of such
    Submitted Bids, and
 
      (2) each Submitted Bid from Potential Holders specifying the Winning
    Bid Rate and all other Submitted Bids from Potential Holders specifying
    lower rates per annum were accepted, thus entitling the Potential
    Holders to purchase the AMPS that are the subject of such Submitted
    Bids, would result in the number of shares subject to all Submitted
    Bids specifying the Winning Bid Rate or a lower rate per annum being at
    least equal to the Available AMPS.
 
  (ii) Promptly after the Auction Agent has made the determinations pursuant
to Paragraph 10(d)(i), the Auction Agent shall advise the Fund of the Maximum
Applicable Rate and, based on such determinations, the Applicable Rate for the
next succeeding Dividend Period as follows:
 
    (A) if Sufficient Clearing Bids exist, that the Applicable Rate for the
  next succeeding Dividend Period shall be equal to the Winning Bid Rate;
 
    (B) if Sufficient Clearing Bids do not exist (other than because all of
  the outstanding AMPS are the subject of Submitted Hold Orders), that the
  Applicable Rate for the next succeeding Dividend Period shall be equal to
  the Maximum Applicable Rate; or
 
    (C) if all of the outstanding AMPS are the subject of Submitted Hold
  Orders, that the Dividend Period next succeeding the Auction automatically
  shall be the same length as the immediately preceding Dividend Period and
  the Applicable Rate for the next succeeding Dividend Period shall be equal
  to 40% of the Reference Rate (or 60% of such rate if the Fund has provided
  notification to the Auction Agent prior to the Auction establishing the
  Applicable Rate for any dividend that net capital gains or other taxable
  income will be included in such dividend on the AMPS) on the date of the
  Auction.
 
PARAGRAPH 10(E) ACCEPTANCE AND REJECTION OF SUBMITTED BIDS AND SUBMITTED SELL
ORDERS AND ALLOCATION OF SHARES.
 
  Based on the determinations made pursuant to Paragraph 10(d)(i), the
Submitted Bids and Submitted Sell Orders shall be accepted or rejected and the
Auction Agent shall take such other action as set forth below:
 
    (i) If Sufficient Clearing Bids have been made, subject to the provisions
  of Paragraph 10(e)(iii) and Paragraph 10(e)(iv), Submitted Bids and
  Submitted Sell Orders shall be accepted or rejected in the following order
  of priority and all other Submitted Bids shall be rejected:
 
      (A) the Submitted Sell Orders of Existing Holders shall be accepted
    and the Submitted Bid of each of the Existing Holders specifying any
    rate per annum that is higher than the Winning Bid Rate shall be
    accepted, thus requiring each such Existing Holder to sell the
    outstanding AMPS that are the subject of such Submitted Sell Order or
    Submitted Bid;
 
                                      E-5
<PAGE>
 
      (B) the Submitted Bid of each of the Existing Holder specifying any
    rate per annum that is lower than the Winning Bid Rate shall be
    rejected, thus entitling each such Existing Holder to continue to hold
    the outstanding AMPS that are the subject of such Submitted Bid;
 
      (C) the Submitted Bid of each of the Potential Holders specifying any
    rate per annum that is lower than the Winning Bid Rate shall be
    accepted;
 
      (D) the Submitted Bid of each of the Existing Holders specifying a
    rate per annum that is equal to the Winning Bid Rate shall be rejected,
    thus entitling each such Existing Holder to continue to hold the
    outstanding AMPS that are the subject of such Submitted Bid, unless the
    number of outstanding AMPS subject to all such Submitted Bids shall be
    greater than the number of outstanding AMPS ("Remaining Shares") equal
    to the excess of the Available AMPS over the number of outstanding AMPS
    subject to Submitted Bids described in Paragraph 10(e)(i)(B) and
    Paragraph 10(e)(i)(C), in which event the Submitted Bids of each such
    Existing Holder shall be accepted, and each such Existing Holder shall
    be required to sell outstanding AMPS, but only in an amount equal to
    the difference between (1) the number of outstanding AMPS then held by
    such Existing Holder subject to such Submitted Bid and (2) the number
    of AMPS obtained by multiplying (x) the number of Remaining Shares by
    (y) a fraction the numerator of which shall be the number of
    outstanding shares of AMPS held by such Existing Holder subject to such
    Submitted Bid and the denominator of which shall be the sum of the
    numbers of outstanding AMPS subject to such Submitted Bids made by all
    such Existing Holders that specified a rate per annum equal to the
    Winning Bid Rate; and
 
      (E) the Submitted Bid of each of the Potential Holders specifying a
    rate per annum that is equal to the Winning Bid Rate shall be accepted
    but only in an amount equal to the number of outstanding AMPS obtained
    by multiplying (x) the difference between the Available AMPS and the
    number of outstanding AMPS subject to Submitted Bids described in
    Paragraph 10(e)(i)(B), Paragraph 10(e)(i)(C) and Paragraph 10(e)(i)(D)
    by (y) a fraction the numerator of which shall be the number of
    outstanding AMPS subject to such Submitted Bid and the denominator of
    which shall be the sum of the number of outstanding AMPS subject to
    such Submitted Bids made by all such Potential Holders that specified
    rates per annum equal to the Winning Bid Rate.
 
    (ii) If Sufficient Clearing Bids have not been made (other than because
  all of the outstanding AMPS are subject to Submitted Hold Orders), subject
  to the provisions of Paragraph 10(e)(iii), Submitted Orders shall be
  accepted or rejected as follows in the following order of priority and all
  other Submitted Bids shall be rejected:
 
      (A) the Submitted Bid of each Existing Holder specifying any rate per
    annum that is equal to or lower than the Maximum Applicable Rate shall
    be rejected, thus entitling such Existing Holder to continue to hold
    the outstanding AMPS that are the subject of such Submitted Bid;
 
      (B) the Submitted Bid of each Potential Holder specifying any rate
    per annum that is equal to or lower than the Maximum Applicable Rate
    shall be accepted, thus requiring such Potential Holder to purchase the
    outstanding AMPS that are the subject of such Submitted Bid; and
 
      (C) the Submitted Bids of each Existing Holder specifying any rate
    per annum that is higher than the Maximum Applicable Rate shall be
    accepted and the Submitted Sell Orders of each Existing Holder shall be
    accepted, in both cases only in an amount equal to the difference
    between (1) the number of outstanding AMPS then held by such Existing
    Holder subject to such Submitted Bid or Submitted Sell Order and (2)
    the number of AMPS obtained by multiplying (x) the difference between
    the Available AMPS and the aggregate number of outstanding AMPS subject
    to Submitted Bids described in Paragraph 10(e)(ii)(A) and Paragraph
    10(e)(ii)(B) by (y) a fraction the numerator of which shall be the
    number of outstanding AMPS held by such Existing Holder subject to such
    Submitted Bid or Submitted Sell Order and the denominator of which
    shall be the number of outstanding AMPS subject to all such Submitted
    Bids and Submitted Sell Orders.
 
    (iii) If, as a result of the procedures described in Paragraph 10(e)(i)
  or Paragraph 10(e)(ii), any Existing Holder would be entitled or required
  to sell, or any Potential Holder would be entitled or required to
 
                                      E-6
<PAGE>
 
  purchase, a fraction of a share of AMPS on any Auction Date, the Auction
  Agent shall, in such manner as in its sole discretion it shall determine,
  round up or down the number of shares of AMPS to be purchased or sold by
  any Existing Holder or Potential Holder on such Auction Date so that each
  outstanding AMPS purchased or sold by each Existing Holder or Potential
  Holder on such Auction Date shall be a whole share of AMPS.
 
    (iv) If, as a result of the procedures described in Paragraph 10(e)(i),
  any Potential Holder would be entitled or required to purchase less than a
  whole share of AMPS on any Auction Date, the Auction Agent, in such manner
  as in its sole discretion it shall determine, shall allocate shares of AMPS
  for purchase among Potential Holders so that only whole shares of AMPS are
  purchased on such Auction Date by any Potential Holder, even if such
  allocation results in one or more of such Potential Holders not purchasing
  any AMPS on such Auction Date.
 
    (v) Based on the results of each Auction, the Auction Agent shall
  determine, with respect to each Broker-Dealer that submitted Bids or Sell
  Orders on behalf of Existing Holders or Potential Holders, the aggregate
  number of the outstanding AMPS to be purchased and the aggregate number of
  outstanding AMPS to be sold by such Potential Holders and Existing Holders
  and, to the extent that such aggregate number of outstanding shares to be
  purchased and such aggregate number of outstanding shares to be sold
  differ, the Auction Agent shall determine to which other Broker-Dealer or
  Broker-Dealers acting for one or more purchasers such Broker-Dealer shall
  deliver, or from which other Broker-Dealer or Broker-Dealers acting for one
  or more sellers such Broker-Dealer shall receive, as the case may be,
  outstanding AMPS.
 
PARAGRAPH 10(F) MISCELLANEOUS.
 
  The Fund may interpret the provisions of this Paragraph 10 to resolve any
inconsistency or ambiguity, remedy any formal defect or make any other change
or modification that does not substantially adversely affect the rights of
Beneficial Owners of AMPS. A Beneficial Owner or an Existing Holder (A) may
sell, transfer or otherwise dispose of AMPS only pursuant to a Bid or Sell
Order in accordance with the procedures described in this Paragraph 10 or to
or through a Broker-Dealer, provided that in the case of all transfers other
than pursuant to Auctions such Beneficial Owner or Existing Holder, its
Broker-Dealer, if applicable, or its Agent Member advises the Auction Agent of
such transfer and (B) except as otherwise required by law, shall have the
ownership of the AMPS held by it maintained in book entry form by the
Securities Depository in the account of its Agent Member, which in turn will
maintain records of such Beneficial Owner's beneficial ownership. Neither the
Fund nor any Affiliate (other than Merrill Lynch, Pierce, Fenner & Smith
Incorporated) shall submit an Order in any Auction. Any Beneficial Owner that
is an Affiliate (other than Merrill Lynch, Pierce, Fenner & Smith
Incorporated) shall not sell, transfer or otherwise dispose of AMPS to any
Person other than the Fund. All of the outstanding AMPS of a Series shall be
represented by a single certificate registered in the name of the nominee of
the Securities Depository unless otherwise required by law or unless there is
no Securities Depository. If there is no Securities Depository, at the Fund's
option and upon its receipt of such documents as it deems appropriate, any
AMPS may be registered in the Stock Register in the name of the Beneficial
Owner thereof and such Beneficial Owner thereupon will be entitled to receive
certificates therefor and required to deliver certificates thereof or upon
transfer or exchange thereof.

ITEM 29. INDEMNIFICATION.
 
 
  Section 5.3 of the Registrant's Declaration of Trust provides as follows:
 
    "The Trust shall indemnify each of its Trustees, officers, employees, and
  agents (including persons who serve at its request 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 5.1 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."
 
                                      C-2
<PAGE>
 
  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.

days, such rate shall be the Interest Equivalent of the 120-day rate on such

Series A; or the Auction Market Preferred Shares, Series B.

     "AMPS Basic Maintenance Amount," as of any Valuation Date, means the dollar
amount equal to (i) the sum of (A) the product of the number of AMPS of each
series and Other AMPS Outstanding on such Valuation Date multiplied by the sum
of (a) $25,000 and (b) any applicable redemption premium attributable to the
designation of a Premium Call Period; (B) the aggregate amount of cash dividends
(whether or not earned or declared) that will have accumulated for each share of
AMPS and Other AMPS Outstanding, in each case, to (but not including) the end of
the current Dividend Period for each series of AMPS that follows such Valuation
Date in the event the then current Dividend Period will end within 49 calendar
days of such Valuation Date or through the 49th day after such Valuation Date in
the event the then current Dividend Period for each series of AMPS will not end
within 49 calendar days of such Valuation Date; (C) in the event the then
current Dividend Period will end within 49 calendar days of such Valuation Date,
the aggregate amount of cash dividends that would accumulate at the Maximum
Applicable Rate applicable to a Dividend Period of 28 or fewer days on any AMPS

day after such Valuation Date, multiplied by the larger of the Moody's
Volatility Factor and the S&P Volatility Factor, determined from time to time by
Moody's and S&P, respectively (except that if such Valuation Date occurs during
a Non-Payment Period, the cash dividend for purposes of calculation would
accumulate at the then current Non-Payment Period Rate); (D) the amount of
anticipated expenses of the Trust for the 90 days subsequent to such Valuation
Date (including any premiums payable with respect to a Policy); (E) the amount
of the Trust's Maximum Potential Additional Dividend Liability as of such
Valuation Date; and (F) any current liabilities as of such Valuation Date to the
extent not reflected in any of (i)(A) through (i)(E) (including, without
limitation, and immediately upon determination, any amounts due and payable by
the Trust pursuant to repurchase agreements and any amounts payable for Florida
Municipal Bonds or Municipal Bonds purchased as of such Valuation Date) less
(ii) either (A) the Discounted Value of any of the Trust's assets, or (B) the
face value of any of the Trust's assets if such assets mature prior to or on the
date of redemption of AMPS or payment of a liability and are either securities
issued or guaranteed by the United States Government or Deposit Securities, in

For purposes of the maximum underlying obligor requirement described above, any
Florida Municipal Bond or Municipal Bond backed by the guaranty, letter of
credit or insurance issued by a third party will be deemed to be issued by such
third party if the issuance of such third party credit is the sole determinant
of the rating on such Bond.  For purposes of the issue type concentration
requirement described above, Florida Municipal Bonds and Municipal Bonds will be
classified within one of the following categories:  health care issues (teaching
and non-teaching hospitals, public and private), housing issues (single- and
multi-family), educational facilities issues (public and private schools),
student loan issues, resource recovery issues, transportation issues (mass
transit, airport and highway bonds), industrial revenue/pollution control bond

calculating the AMPS Basic Maintenance Amount.  When the Trust purchases a
Florida Municipal Bond or Municipal Bond and agrees to sell it at a future date
to another party, cash receivable by the Trust thereby will constitute a Moody's
Eligible Asset if the long-term debt of such other party is rated at least A2 by
Moody's and such agreement has a term of 30 days or less; otherwise the
Discounted Value of such Bond will constitute a Moody's Eligible Asset.

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

in 30 days or less, or 120% so long as such Florida Municipal Bonds are rated A-
1 or SP-1 by S&P and mature or have a demand feature exercisable in 30 days or
less, or 125% if such Florida Municipal Bonds are not rated by S&P but are rated
VMIG-1, P-1 or MIG-1 by Moody's or F-1 + by Fitch; provided, however, such
short-term Florida Municipal Bonds rated by Moody's or Fitch but not rated by
S&P having a demand feature exercisable in 30 days or less must be backed by a
letter of credit, liquidity facility or guarantee from a bank or other financial

"Receivables for Florida Municipal Bonds Sold," for purposes of calculating S&P
Eligible Assets as of any Valuation Date, means the book value of receivables
for Florida Municipal Bonds sold as of or prior to such Valuation Date. The

will not adversely affect its then current rating on the AMPS. For purposes of
the foregoing, Anticipation Notes rated SP-1 or, if not rated by S&P, rated

Florida Municipal Bonds will be included in S&P Eligible Assets only to the
extent the Market Value of such Florida Municipal Bonds does not exceed 50% of
the aggregate Market Value of the S&P Eligible Assets; and further provided
that, for purposes of determining the S&P Discount Factor applicable to any such
Moody's-rated or Fitch-rated Florida Municipal Bond, such Florida Municipal Bond
will be deemed to have an S&P rating which is one full rating category lower
than its Moody's rating or Fitch rating); (iv) is not subject to a covered call
or covered put option written by the Trust; (v) except for Inverse Floaters, is
not part of a private placement of Florida Municipal Bonds; and (vi) except for
Inverse Floaters, is part of an issue of Florida Municipal Bonds with an
original issue size of at least $10 million or, if of an issue with an original

     bond insurers) will be considered S&P Eligible Assets only to the extent
     the Market Value of such Florida Municipal Bonds does not exceed 10% of the
     aggregate Market Value of the S&P Eligible Assets, provided that 2% is
     added to the applicable S&P Discount Factor for every 1% by which the
     Market Value of such Florida Municipal Bonds exceeds 5% of the aggregate
     Market Value of the S&P Eligible Assets;

          (2) Florida Municipal Bonds of any one issue type category (as
     described below) will be considered S&P Eligible Assets only to the extent
     the Market Value of such Bonds does not exceed 25% of the aggregate Market
     Value of S&P Eligible Assets, except that Florida Municipal Bonds falling
     within the utility issue type category will be broken down into three sub-
     categories (as described below) and such Florida Municipal Bonds will be
     considered S&P Eligible Assets to the extent the Market Value of such Bonds
     in each such sub-category does not exceed 25% of the aggregate Market Value
     of S&P Eligible Assets, except that Florida Municipal Bonds falling within
     the transportation issue type category will be broken down into two sub-

     of the aggregate Market Value of S&P Eligible Assets and except that
     Florida Municipal Bonds falling within the general obligation issue type
     category will be considered S&P Eligible Assets to the extent the Market
     Value of such Bonds does not exceed 50% of the aggregate Market Value of
     S&P Eligible Assets. For purposes of the issue type category requirement
     described above, Florida Municipal Bonds will be classified within one of
     the following categories: health care issues, housing issues, educational
     facilities issues, student loan issues, transportation issues, industrial
     development bond issues, utility issues, general obligation issues, lease
     obligations, escrowed bonds and other issues not falling within one of the
     aforementioned categories. The general obligation issue type category
     includes any issuer that is directly or indirectly guaranteed by the State
     of Florida or its political subdivisions. Utility issuers are included in
     the general obligation issue type category if the issuer is directly or
     indirectly guaranteed by the State of Florida or its political
     subdivisions. For purposes of the issue type 

                                       20
<PAGE>
 
     category requirement described above, Florida Municipal Bonds in the
     utility issue type category will be classified within one of the three
     following sub-categories: (i) electric, gas and combination issues (if the
     combination issue includes an electric issue), (ii) water and sewer
     utilities and combination issues (if the combination issue does not include
     an electric issue), and (iii) irrigation, resource recovery, solid waste
     and other utilities, provided that Florida Municipal Bonds included in this
     sub-category (iii) must be rated by S&P in order to be included in S&P
     Eligible Assets. For purposes of the issue type category requirement
     described above, Florida Municipal Bonds in the transportation issue type
     category will be classified within one of the two following sub-categories:
     (i) streets and highways, toll roads, bridges and tunnels, airports and
     multi-purpose port authorities (multiple revenue streams generated by toll
     roads, airports, real estate, bridges), (ii) mass transit, parking,
     seaports and others. Exposure to transportation sub-category (i) in the
     preceding sentence is limited to 25% of the aggregate Market Value of S&P
     Eligible Assets, provided, however, exposure to transportation sub-category
     (ii) in the preceding sentence can exceed the 25% limit to the extent that
     exposure to transportation sub-category (ii) is reduced, for a total
     exposure up to and not exceeding 40% of the aggregate Market Value of S&P
     Eligible Assets for the transportation issue type category; and

          (3) Florida Municipal Bonds which are escrow bonds or defeased bonds
     may compose up to 100% of the aggregate Market Value of S&P Eligible Assets
     if such Bonds initially are assigned a rating by S&P in accordance with
     S&P's legal defeasance criteria or rerated by S&P as economic defeased
     escrow bonds and assigned an AAA rating. Florida Municipal Bonds may be
     rated as escrow bonds by another nationally recognized rating agency or
     rerated as an escrow bond and assigned the equivalent of an S&P AAA rating,
     provided that such equivalent rated Bonds are limited to 50% of the
     aggregate Market Value of S&P Eligible Assets and are deemed to have an AA
     S&P rating for purposes of determining the S&P Discount Factor applicable
     to such Florida Municipal Bonds. The limitations on Florida Municipal Bonds
     of any one issuer in clause (1) above are not applicable to escrow bonds,
     however, economically defeased bonds that are either initially rated or
     rerated by S&P or another nationally recognized

     will remain in its original issue type category set forth in clause (2)
     above. Florida Municipal Bonds that are legally defeased and secured by
     securities issued or guaranteed by the United States Government are not
     required to meet the minimum issuance size requirement set forth above.

     The Trust may include Municipal Bonds other than Florida Municipal Bonds as

S&P provided that S&P advises the Trust in writing that such action will not
adversely affect its then current rating on the AMPS.

     "U.S. Treasury Note Rate" on any date means (i) the yield as calculated by
reference to the bid price quotation of the actively traded, current coupon
Treasury Note with a maturity most nearly comparable to the length of the
related Dividend Period, as such bid price quotation is published on the
Business Day immediately preceding such date by the Federal Reserve Bank of New
York in its Composite 3:30 P.M. Quotations for U.S. Government Securities report
for such Business Day, or (ii) if such yield as so calculated is not available,
the Alternate Treasury Note Rate on such date.  "Alternate Treasury Note Rate"
on any date means the yield as calculated by reference to the arithmetic average
of the bid price quotations of the actively traded, current coupon Treasury Note
with a maturity most nearly comparable to the length of the related Dividend
Period, as determined by the bid price quotations as of any time on the Business
Day immediately preceding such date, obtained from at least three recognized
primary U.S. Government securities dealers selected by the Auction Agent.

     "Valuation Date" means, for purposes of determining whether the Trust is
maintaining the AMPS Basic Maintenance Amount, each Business Day commencing with
the Date of Original Issue.

     "Variation Margin" means, in connection with an outstanding futures
contract owned or sold by the Trust, the amount of cash or securities paid to or
received from a broker (subsequent to the Initial Margin payment) from time to
time as the price of such futures contract fluctuates.

     (b) The foregoing definitions of Accountant's Confirmation, AMPS Basic
Maintenance Amount, AMPS Basic Maintenance Cure Date, AMPS Basic Maintenance
Report, Deposit Securities, Discounted Value, Independent Accountant, Initial
Margin, Inverse Floaters, Market Value, Maximum Potential Additional Dividend
Liability, Moody's Discount Factor, Moody's Eligible Asset, Moody's Exposure
Period, Moody's Hedging Transactions, Moody's Volatility Factor, S&P Discount
Factor, S&P Eligible Asset, S&P Exposure Period, S&P Hedging Transactions, S&P
Volatility Factor, Valuation Date and Variation Margin have been determined by
the Board of Trustees of the Trust in order to obtain a "aaa" rating from
Moody's and a AAA rating from S&P on the AMPS on their Date of Original Issue;
and the Board of Trustees of the 

                                       25
<PAGE>
 
Trust shall have the authority, without shareholder approval, to amend, alter or
repeal from time to time the foregoing definitions and the restrictions and
guidelines set forth thereunder if Moody's and S&P or any Substitute Rating
Agency advises the Trust in writing that such amendment, alteration or repeal
will not adversely affect their then current ratings on the AMPS.

     2. Dividends. (a) The Holders shall be entitled to receive, when, as and if
        ----------
declared by the Board of Trustees of the Trust, out of funds legally available
therefor, cumulative dividends each consisting of (i) cash at the Applicable
Rate, (ii) a Right to receive cash as set forth in paragraph 2(e) below, and
(iii) any additional amounts as set forth in paragraph 2(f) below, and no more,
payable on the respective dates set forth below. Dividends on the AMPS so
declared and payable shall be paid (i) in preference to and in priority over any
dividends declared and payable on the Common Shares, and (ii) to the extent
permitted under the Code and to the extent available, out of net tax-exempt
income earned on the Trust's investments. To the extent permitted under the
Code, dividends on AMPS will be designated as exempt-interest dividends. For the
purposes of this section, the term "net tax-exempt income" shall exclude capital
gains of the Trust.

     (b) (i) Cash dividends on AMPS shall accumulate from the Date of Original
Issue and shall be payable, when, as and if declared by the Board of Trustees,
out of funds legally available therefor, commencing on the Initial Dividend
Payment Date with respect to each series of AMPS. Following the Initial Dividend
Payment Date for each series of AMPS, dividends on each series of AMPS will be
payable, at the option of the Trust, either (i) with respect to any 7-Day
Dividend Period and any Short Term Dividend Period of 35 or fewer days, on the
day next succeeding the last day thereof or (ii) with respect to any Short Term
Dividend Period of more than 35 days and with respect to any Long Term Dividend
Period, monthly on the first Business Day of each calendar month during such
Short Term Dividend Period or Long Term Dividend Period and on the day next
succeeding the last day thereof (each such date referred to in clause (i) or
(ii) being herein referred to as a "Normal Dividend Payment Date"), except that
if such Normal Dividend Payment Date is not a Business Day, then the Dividend
Payment Date shall be the first Business Day next succeeding such Normal
Dividend Payment Date. Although any particular Dividend Payment Date may not
occur on the originally scheduled date because of the exceptions discussed
above, the next succeeding Dividend Payment Date, subject to such exceptions,
will occur on the next following originally scheduled date. If for any reason a

                                       26
<PAGE>
 
Dividend Payment Date cannot be fixed as described above, then the Board of
Trustees shall fix the Dividend Payment Date. The Board of Trustees by
resolution prior to authorization of a dividend by the Board of Trustees may
change a Dividend Payment Date if such change does not adversely affect the
contract rights of the Holders of AMPS set forth in the Declaration. The Initial
Dividend Period, 7-Day Dividend Periods and Special Dividend Periods are
hereinafter sometimes referred to as Dividend Periods. Each dividend payment
date determined as provided above is hereinafter referred to as a "Dividend
Payment Date."

     (ii) Each dividend shall be paid to the Holders as they appear in the Share
Register as of 12:00 noon, New York City time, on the Business Day preceding the
Dividend Payment Date. Dividends in arrears for any past Dividend Period may be
declared and paid at any time, without reference to any regular Dividend Payment
Date, to the Holders as they appear on the Share Register on a date, not
exceeding 15 days prior to the payment date therefor, as may be fixed by the
Board of Trustees of the Trust.

     (c) (i) During the period from and including the Date of Original Issue to
but excluding the Initial Dividend Payment Date for each series of AMPS (the
"Initial Dividend Period"), the Applicable Rate shall be the Initial Dividend
Rate. Commencing on the Initial Dividend Payment Date for each series of AMPS,
the Applicable Rate for each subsequent dividend period (hereinafter referred to
as a "Subsequent Dividend Period"), which Subsequent Dividend Period shall
commence on and include a Dividend Payment Date and shall end on and include the
calendar day prior to the next Dividend Payment Date (or last Dividend Payment
Date in a Dividend Period if there is more than one Dividend Payment Date),
shall be equal to the rate per annum that results from implementation of the
Auction Procedures.

     The Applicable Rate for each Dividend Period commencing during a Non-
Payment Period shall be equal to the Non-Payment Period Rate; and each Dividend
Period, commencing after the first day of, and during, a Non-Payment Period
shall be a 7-Day Dividend Period in the case of each series of AMPS.  Except in
the case of the willful failure of the Trust to pay a dividend on a Dividend
Payment Date or to redeem any AMPS on the date set for such redemption, any
amount of any dividend due on any Dividend Payment Date (if, prior to the close
of business on the second Business Day preceding such Dividend Payment Date, the
Trust has declared such dividend payable on such Dividend Payment Date to the
Holders of such 

                                       27
<PAGE>
 
AMPS as of 12:00 noon, New York City time, on the Business Day preceding such
Dividend Payment Date) or redemption price with respect to any AMPS not paid to
such Holders when due may be paid to such Holders in the same form of funds by
12:00 noon, New York City time, on any of the first three Business Days after
such Dividend Payment Date or due date, as the case may be, provided that, such
amount is accompanied by a late charge calculated for such period of non-payment
at the Non-Payment Period Rate applied to the amount of such non-payment based
on the actual number of days comprising such period divided by 365. In the case
of a willful failure of the Trust to pay a dividend on a Dividend Payment Date
or to redeem any AMPS on the date set for such redemption, the preceding
sentence shall not apply and the Applicable Rate for the Dividend Period
commencing during the Non-Payment Period resulting from such failure shall be
the Non-Payment Period Rate. For the purposes of the foregoing, payment to a
person in same-day funds on any Business Day at any time shall be considered
equivalent to payment to such person in New York Clearing House (next-day) funds
at the same time on the preceding Business Day, and any payment made after 12:00
noon, New York City time, on any Business Day shall be considered to have been
made instead in the same form of funds and to the same person before 12:00 noon,
New York City time, on the next Business Day.

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

     (iii)  With respect to each Dividend Period that is a Special Dividend
Period, the Trust may, at its sole option and to the extent permitted by law, by
telephonic and written notice (a

                                       28
<PAGE>
 
"Request for Special Dividend Period") to the Auction Agent and to each Broker-
Dealer, request that the next succeeding Dividend Period for a series of AMPS be
a number of days (other than seven), evenly divisible by seven, and not fewer
than seven nor more than 364 in the case of a Short Term Dividend Period or one
whole year or more but not greater than five years in the case of a Long Term
Dividend Period, specified in such notice, provided that the Trust may not give
a Request for Special Dividend Period of greater than 28 days (and any such
request shall be null and void) unless, for any Auction occurring after the
initial Auction, Sufficient Clearing Bids were made in the last occurring
Auction and unless full cumulative dividends, any amounts due with respect to
redemptions, and any Additional Dividends payable prior to such date have been
paid in full. Such Request for Special Dividend Period, in the case of a Short
Term Dividend Period, shall be given on or prior to the second Business Day but
not more than seven Business Days prior to an Auction Date for a series of AMPS
and, in the case of a Long Term Dividend Period, shall be given on or prior to
the second Business Day but not more than 28 days prior to an Auction Date for
the AMPS. Upon receiving such Request for Special Dividend Period, the Broker-
Dealer(s) shall jointly determine whether, given the factors set forth below, it
is advisable that the Trust issue a Notice of Special Dividend Period for the
series of AMPS as contemplated by such Request for Special Dividend Period and
the Optional Redemption Price of the AMPS during such Special Dividend Period
and the Specific Redemption Provisions and shall give the Trust and the Auction
Agent written notice (a "Response") of such determination by no later than the
second Business Day prior to such Auction Date. In making such determination the
Broker-Dealer(s) will consider (1) existing short-term and long-term market
rates and indices of such short-term and long-term rates, (2) existing market
supply and demand for short-term and long-term securities, (3) existing yield
curves for short-term and long-term securities comparable to the AMPS, (4)
industry and financ ial conditions which may affect the AMPS, (5) the investment
objective of the Trust, and (6) the Dividend Periods and dividend rates at which
current and potential beneficial holders of the AMPS would remain or become
beneficial holders. If the Broker-Dealer(s) shall not give the Trust and the
Auction Agent a Response by such second Business Day or if the Response states
that given the factors set forth above it is not advisable that the Trust give a
Notice of Special Dividend Period for the series of AMPS, the Trust may not give
a Notice of Special Dividend Period in respect of such Request for Special
Dividend Period. In the event the Response indicates that it is advisable that
the

                                       29
<PAGE>
 
Trust give a Notice of Special Dividend Period for the series of AMPS, the
Trust may by no later than the second Business Day prior to such Auction Date
give a notice (a "Notice of Special Dividend Period") to the Auction Agent, the
Securities Depository and each Broker-Dealer which notice will specify (i) the
duration of the Special Dividend Period, (ii) the Optional Redemption Price as
specified in the related Response and (iii) the Specific Redemption Provisions,
if any, as specified in the related Response. The Trust also shall provide a
copy of such Notice of Special Dividend Period to Moody's and S&P. The Trust
shall not give a Notice of Special Dividend Period and, if the Trust has given a
Notice of Special Dividend Period, the Trust is required to give telephonic and
written notice of its revocation (a "Notice of Revocation") to the Auction
Agent, each Broker-Dealer, and the Securities Depository on or prior to the
Business Day prior to the relevant Auction Date if (x) either the 1940 Act AMPS
Asset Coverage is not satisfied or the Trust shall fail to maintain S&P Eligible
Assets and Moody's Eligible Assets each with an aggregate Discounted Value at
least equal to the AMPS Basic Maintenance Amount, in each case on each of the
two Valuation Dates immediately preceding the Business Day prior to the relevant
Auction Date on an actual basis and on a pro forma basis giving effect to the
proposed Special Dividend Period (using as a pro forma dividend rate with
respect to such Special Dividend Period the dividend rate which the Broker-
Dealers shall advise the Trust is an approximately equal rate for securities
similar to the AMPS with an equal dividend period), provided that, in
calculating the aggregate Discounted Value of Moody's Eligible Assets for this
purpose, the Moody's Exposure Period shall be deemed to be one week longer, (y)
sufficient funds for the payment of dividends payable on the immediately
succeeding Dividend Payment Date have not been irrevocably deposited with the
Auction Agent by the close of business on the third Business Day preceding the
related Auction Date or (z) the Broker-Dealer(s) jointly advise the Trust that
after consideration of the factors listed above they have concluded that it is
advisable to give a Notice of Revocation. The Trust also shall provide a copy of
such Notice of Revocation to Moody's and S&P. If the Trust is prohibited from
giving a Notice of Special Dividend Period as a result of any of the factors
enumerated in clause (x), (y) or (z) above or if the Trust gives a Notice of
Revocation with respect to a Notice of Special Dividend Period for any series of
AMPS, the next succeeding Dividend Period will be a 7-Day Dividend Period in the
case of Series A AMPS and Series B AMPS. In addition, in the event Sufficient
Clearing Bids are not made in the applicable Auction or such Auction is not held
for

                                       30
<PAGE>
 
any reason, such next succeeding Dividend Period will be a 7-Day Dividend Period
(in the case of Series A AMPS and Series B AMPS) and the Trust may not again
give a Notice of Special Dividend Period for the AMPS (and any such attempted
notice shall be null and void) until Sufficient Clearing Bids have been made in
an Auction with respect to a 7-Day Dividend Period (in the case of Series A AMPS
and Series B AMPS).

     (d) (i) Holders shall not be entitled to any dividends, whether payable in
cash, property or shares, in excess of full cumulative dividends and applicable
late charges, as herein provided, on the AMPS (except for Additional Dividends
as provided in paragraph 2(e) hereof and additional payments as provided in
paragraph 2(f) hereof). Except for the late charge payable pursuant to paragraph
2(c)(i) hereof, no interest, or sum of money in lieu of interest, shall be
payable in respect of any dividend payment on the AMPS that may be in arrears.

     (ii) For so long as any share of AMPS is Outstanding, the Trust shall not
declare, pay or set apart for payment any dividend or other distribution (other
than a dividend or distribution paid in shares of, or options, warrants or
rights to subscribe for or purchase, Common Shares or other shares of beneficial
interest, if any, ranking junior to the AMPS as to dividends or upon
liquidation) in respect of the Common Shares or any other shares of the Trust
ranking junior to or on a parity with the AMPS as to dividends or upon
liquidation, or call for redemption, redeem, purchase or otherwise acquire for
consideration any shares of the Common Shares or any other such junior shares of
beneficial interest (except by conversion into or exchange for shares of the
Trust ranking junior to the AMPS as to dividends and upon liquidation) or any
other such Parity Shares (except by conversion into or exchange for shares of
the Trust ranking junior to or on a parity with the AMPS as to dividends and
upon liquidation), unless (A) immediately after such transaction, the Trust
shall have S&P Eligible Assets and Moody's Eligible Assets each with an
aggregate Discounted Value equal to or greater than the AMPS Basic Maintenance
Amount and the Trust shall maintain the 1940 Act AMPS Asset Coverage, (B) full
cumulative dividends on AMPS and shares of Other AMPS due on or prior to the
date of the transaction have been declared and paid or shall have been declared
and sufficient funds for the payment thereof deposited with the Auction Agent,
(C) any Additional Dividend required to be paid under paragraph 2(e) below on or
before the date of such declaration or payment has been paid and (D) the Trust
has redeemed the full number of AMPS required to be redeemed by any provision
for mandatory redemption contained herein.

                                       31
<PAGE>
 
     (e) Each dividend shall consist of (i) cash at the Applicable Rate, (ii) an
uncertificated right (a "Right") to receive an Additional Dividend (as defined
below), and (iii) any additional amounts as set forth in paragraph 2(f) below.
Each Right shall thereafter be independent of the AMPS on which the dividend was
paid. The Trust shall cause to be maintained a record of each Right received by
the respective Holders. A Right may not be transferred other than by operation
of law. If the Trust retroactively allocates any net capital gains or other
income subject to regular Federal income taxes to AMPS without having given
advance notice thereof to the Auction Agent as described in paragraph 2(f)
hereof solely by reason of the fact that such allocation is made as a result of
the redemption of all or a portion of the outstanding AMPS or the liquidation of
the Trust (the amount of such allocation referred to herein as a "Retroactive
Taxable Allocation"), the Trust will, within 90 days (and generally within 60
days) after the end of the Trust's fiscal year for which a Retroactive Taxable
Allocation is made, provide notice thereof to the Auction Agent and to each
holder of a Right applicable to such AMPS (initially Cede & Co. as nominee of
The Depository Trust Company) during such fiscal year at such holder's address
as the same appears or last appeared on the Share Books of the Trust. The Trust
will, within 30 days after such notice is given to the Auction Agent, pay to the
Auction Agent (who will then distribute to such holders of Rights), out of funds
legally available therefor, an amount equal to the aggregate Additional Dividend
with respect to all Retroactive Taxable Allocations made to such holders during
the fiscal year in question.

     An "Additional Dividend" means payment to a present or former holder of
AMPS of an amount which, when taken together with the aggregate amount of
Retroactive Taxable Allocations made to such holder with respect to the fiscal
year in question, would cause such holder's dividends in dollars (after Federal
and Florida income tax consequences) from the aggregate of both the Retroactive
Taxable Allocations and the Additional Dividend to be equal to the dollar amount
of the dividends which would have been received by such holder if the amount of
the aggregate Retroactive Taxable Allocations would have been excludable from
the gross income of such holder.  Such Additional Dividend shall be calculated
(i) without consideration being given to the time value of money; (ii) assuming
that no holder of AMPS is subject to the Federal alternative minimum tax with
respect to dividends received from the Trust; and (iii) assuming that each
Retroactive Taxable Allocation would be taxable in the hands of each holder of
AMPS at the greater of: (x) the maximum marginal regular Federal individual
income tax rate 

                                       32
<PAGE>
 
applicable to ordinary income or capital gains depending on the taxable
character of the distribution (including any surtax); or (y) the maximum
combined marginal regular Federal and Florida corporate income tax rate
applicable to ordinary income or capital gains depending on the taxable
character of the distribution (taking into account in both (x) and (y) the
Federal income tax deductibility of state taxes paid or incurred but not any
phase out of, or provision limiting, personal exemptions, itemized deductions,
or the benefit of lower tax brackets and assuming the taxability of Federally
tax-exempt dividends for corporations for Florida income tax purposes).

     (f) Except as provided below, whenever the Trust intends to include any net
capital gains or other income subject to regular Federal income taxes in any
dividend on AMPS, the Trust will notify the Auction Agent of the amount to be so
included at least five Business Days prior to the Auction Date on which the
Applicable Rate for such dividend is to be established. The Trust may also
include such income in a dividend on shares of a series of AMPS without giving
advance notice thereof if it increases the dividend by an additional amount
calculated as if such income was a Retroactive Taxable Allocation and the
additional amount was an Additional Dividend, provided that the Trust will
notify the Auction Agent of the additional amounts to be included in such
dividend at least five Business Days prior to the applicable Dividend Payment
Date.

     (g)  No fractional AMPS shall be issued.

     3. Liquidation Rights. Upon any liquidation, dissolution or winding up of
        ------------------
the Trust, whether voluntary or involuntary, the Holders shall be entitled to
receive, out of the assets of the Trust available for distribution to
shareholders, before any distribution or payment is made upon any Common Shares
or any other shares of beneficial interest ranking junior in right of payment
upon liquidation to the AMPS, the sum of $25,000 per share plus accumulated but
unpaid dividends (whether or not earned or declared) thereon to the date of
distribution, and after such payment the Holders will be entitled to no other
payments other than Additional Dividends as provided in paragraph 2(e) hereof.
If upon any liquidation, dissolution or winding up of the Trust, the amounts
payable with respect to the AMPS and any other Outstanding class or series of
Preferred Shares of the Trust ranking on a parity with the AMPS as to payment
upon liquidation are not paid in full, the Holders and the holders of such other
class or series will share 

                                       33
<PAGE>
 
ratably in any such distribution of assets in proportion to the respective
preferential amounts to which they are entitled. After payment of the full
amount of the liquidating distribution to which they are entitled, the Holders
will not be entitled to any further participation in any distribution of assets
by the Trust except for any Additional Dividends. A consolidation, merger or
statutory share exchange of the Trust with or into any other corporation or
entity or a sale, whether for cash, shares of stock, securities or properties,
of all or substantially all or any part of the assets of the Trust shall not be
deemed or construed to be a liquidation, dissolution or winding up of the Trust.

     4.  Redemption.  (a)   Shares of AMPS shall be redeemable by the Trust as
         ----------                                                           
provided below:

             (i) To the extent permitted under the 1940 Act and Massachusetts
     law, upon giving a Notice of Redemption, the Trust at its option may redeem
     AMPS, in whole or in part, out of funds legally available therefor, at the
     Optional Redemption Price per share, on any Dividend Payment Date; provided
     that no share of AMPS may be redeemed at the option of the Trust during (A)
     the Initial Dividend Period with respect to a series of shares or (B) a
     Non-Call Period to which such share is subject. In addition, holders of
     AMPS which are redeemed shall be entitled to receive Additional Dividends
     to the extent provided herein. The Trust may not give a Notice of
     Redemption relating to an optional redemption as described in this
     paragraph 4(a)(i) unless, at the time of giving such Notice of Redemption,
     the Trust has available Deposit Securities with maturity or tender dates
     not later than the day preceding the applicable redemption date and having
     a value not less than the amount due to Holders by reason of the redemption
     of their AMPS on such redemption date.

             (ii) The Trust shall redeem, out of funds legally available
     therefor, at the Mandatory Redemption Price per share, AMPS to the extent
     permitted under the 1940 Act, on a date fixed by the Board of Trustees, if
     the Trust fails to maintain S&P Eligible Assets and Moody's Eligible Assets
     each with an aggregate Discounted Value equal to or greater than the AMPS
     Basic Maintenance Amount as provided in paragraph 7(a) or to satisfy the
     1940 Act AMPS Asset Coverage as provided in paragraph 6 and such failure is
     not cured on or before the AMPS Basic Maintenance Cure Date or the 1940 Act
     Cure

                                       34
<PAGE>
 
     Date (herein collectively referred to as a "Cure Date"), as the case may
     be. In addition, holders of AMPS so redeemed shall be entitled to receive
     Additional Dividends to the extent provided herein. The number of AMPS to
     be redeemed shall be equal to the lesser of (i) the minimum number of AMPS
     the redemption of which, if deemed to have occurred immediately prior to
     the opening of business on the Cure Date, together with all shares of other
     Preferred Shares subject to redemption or retirement, would result in the
     Trust having S&P Eligible Assets and Moody's Eligible Assets each with an
     aggregate Discounted Value equal to or greater than the AMPS Basic
     Maintenance Amount or satisfaction of the 1940 Act AMPS Asset Coverage, as
     the case may be, on such Cure Date (provided that, if there is no such
     minimum number of AMPS and of other Preferred Shares the redemption of
     which would have such result, all AMPS and other Preferred Shares then
     Outstanding shall be redeemed), and (ii) the maximum number of AMPS,
     together with all other Preferred Shares subject to redemption or
     retirement, that can be redeemed out of funds expected to be legally
     available therefor on such redemption date. In determining the number of
     AMPS required to be redeemed in accordance with the foregoing, the Trust
     shall allocate the number required to be redeemed which would result in the
     Trust having S&P Eligible Assets and Moody's Eligible Assets each with an
     aggregate Discounted Value equal to or greater than the AMPS Basic
     Maintenance Amount or satisfaction of the 1940 Act AMPS Asset Coverage, as
     the case may be, pro rata among AMPS of all series, Other AMPS and other
     Preferred Shares subject to redemption pursuant to provisions similar to
     those contained in this paragraph 4(a)(ii); provided that, AMPS which may
     not be redeemed at the option of the Trust due to the designation of a Non-
     Call Period applicable to such shares (A) will be subject to mandatory
     redemption only to the extent that other shares are not available to
     satisfy the number of shares required to be redeemed and (B) will be
     selected for redemption in an ascending order of outstanding number of days
     in the Non-Call Period (with shares with the lowest number of days to be
     redeemed first) and by lot in the event of shares having an equal number of
     days in such Non-Call Period. The Trust shall effect such redemption on a
     Business Day which is not later than 35 days after such Cure Date, except
     that if the Trust does not have funds legally available for the redemption
     of all of the required number of AMPS and other Preferred Shares which are
     subject to mandatory redemption

                                       35
<PAGE>
 
     or the Trust otherwise is unable to effect such redemption on or prior to
     35 days after such Cure Date, the Trust shall redeem those AMPS which it is
     unable to redeem on the earliest practicable date on which it is able to
     effect such redemption out of funds legally available therefor.

     (b) Notwithstanding any other provision of this paragraph 4, no AMPS may be
redeemed pursuant to paragraph 4(a)(i) of this Certificate of Designation (i)
unless all dividends in arrears on all remaining outstanding Parity Shares shall
have been or are being contemporaneously paid or declared and set apart for
payment and (ii) if redemption thereof would result in the Trust's failure to
maintain Moody's Eligible Assets or S&P Eligible Assets with an aggregate
Discounted Value equal to or greater than the AMPS Basic Maintenance Amount. In
the event that less than all the outstanding shares of a series of AMPS are to
be redeemed and there is more than one Holder, the shares of that series of AMPS
to be redeemed shall be selected by lot or such other method as the Trust shall
deem fair and equitable.

     (c) Whenever AMPS are to be redeemed, the Trust, not less than 17 nor more
than 30 days prior to the date fixed for redemption, shall mail a notice
("Notice of Redemption") by first-class mail, postage prepaid, to each Holder of
AMPS to be redeemed and to the Auction Agent. The Trust shall cause the Notice
of Redemption to also be published in the eastern and national editions of The
                                                                           ---
Wall Street Journal. The Notice of Redemption shall set forth (i) the redemption
- -------------------
date, (ii) the amount of the redemption price, (iii) the aggregate number of
AMPS of such series to be redeemed, (iv) the place or places where AMPS of such
series are to be surrendered for payment of the redemption price, (v) a
statement that dividends on the shares to be redeemed shall cease to accumulate
on such redemption date (except that holders may be entitled to Additional
Dividends) and (vi) the provision of this Certificate of Designation pursuant to
which such shares are being redeemed. No defect in the Notice of Redemption or
in the mailing or publication thereof shall affect the validity of the
redemption proceedings, except as required by applicable law.

     If the Notice of Redemption shall have been given as aforesaid and,
concurrently or thereafter, the Trust shall have deposited in trust with the
Auction Agent, or segregated in an account at the Trust's custodian bank for the
benefit of the Auction Agent, Deposit Securities (with a right of substitution)
having an aggregate Discounted Value (utilizing in the case of S&P

                                       36

an S&P Exposure Period of 22 Business Days) equal to the redemption payment for
the AMPS as to which such Notice of Redemption has been given with irrevocable
instructions and authority to pay the redemption price to the Holders of such
shares, then upon the date of such deposit or, if no such deposit is made, then
upon such date fixed for redemption (unless the Trust shall default in making
the redemption payment), all rights of the Holders of such shares as
shareholders of the Trust by reason of the ownership of such shares will cease
and terminate (except their right to receive the redemption price in respect
thereof and any Additional Dividends, but without interest), and such shares
shall no longer be deemed outstanding. The Trust shall be entitled to receive,
from time to time, from the Auction Agent the interest, if any, on such Deposit
Securities deposited with it and the Holders of any shares so redeemed shall
have no claim to any of such interest. In case the Holder of any shares so
called for redemption shall not claim the redemption payment for his shares
within one year after the date of redemption, the Auction Agent shall, upon
demand, pay over to the Trust such amount remaining on deposit and the Auction
Agent shall thereupon be relieved of all responsibility to the Holder of such
shares called for redemption and such Holder thereafter shall look only to the
Trust for the redemption payment.

     5.   Voting Rights.  (a) General.  Except as otherwise provided in the
          -------------       -------   
Declaration or By-Laws, each Holder of AMPS shall be entitled to one vote for
each share held on each matter submitted to a vote of shareholders of the Trust,
and the holders of outstanding Preferred Shares, including AMPS, and of Common
Shares vote together as a single class; provided that, at any meeting of the
shareholders of the Trust held for the election of trustees, the holders of
outstanding Preferred Shares, including AMPS, shall be entitled, as a class, to
the exclusion of the holders of all other securities and classes of shares of
beneficial interest of the Trust, to elect two trustees of the Trust.  Subject
to paragraph 5(b) hereof, the holders of outstanding shares of beneficial
interest of the Trust, including the holders of outstanding Preferred Shares,
including AMPS, voting as a single class, shall elect the balance of the
trustees.

     (b) Right to Elect Majority of Board of Trustees. During any period in
         --------------------------------------------
which any one or more of the conditions described below shall exist (such period
being referred to herein as a "Voting Period"), the number of trustees
constituting the Board of Trustees shall be automatically increased by the
smallest number that, when added to the two trustees elected exclusively by the
holders of Preferred Shares, would constitute a majority of the Board of

                                       37
<PAGE>
 
Trustees as so increased by such smallest number; and the holders of Preferred
Shares shall be entitled, voting separately as one class (to the exclusion of
the holders of all other securities and classes of shares of beneficial interest
of the Trust), to elect such smallest number of additional trustees, together
with the two trustees that such holders are in any event entitled to elect. A
Voting Period shall commence:

          (i)  if at any time accumulated dividends (whether or not earned or
     declared, and whether or not funds are then legally available in an amount
     sufficient therefor) on the outstanding AMPS equal to at least two full
     years' dividends shall be due and unpaid and sufficient cash or specified
     securities shall not have been deposited with the Auction Agent for the
     payment of such accumulated dividends; or
          
          (ii) if at any time holders of any other Preferred Shares are entitled
     to elect a majority of the trustees of the Trust under the 1940 Act.

     Upon the termination of a Voting Period, the voting rights described in
this paragraph 5(b) shall cease, subject always, however, to the reverting of
such voting rights in the Holders upon the further occurrence of any of the
events described in this paragraph 5(b).

     (c) Right to Vote with Respect to Certain Other Matters. So long as any
         ---------------------------------------------------
AMPS are outstanding, the Trust shall not, without the affirmative vote of the
holders of a majority of the Preferred Shares Outstanding at the time, voting
separately as one class: (i) authorize, create or issue any class or series of
shares ranking prior to the AMPS or any other 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 Declaration, whether by
merger, consolidation or otherwise, so as to adversely affect any of the
contract rights expressly set forth in the Declaration of holders of AMPS or any
other Preferred Shares. To the extent permitted under the 1940 Act, in the event
shares of more than one series of AMPS are outstanding, the Trust shall not
approve any of the actions set forth in clause (i) or (ii) which adversely
affects the contract rights expressly set forth in the Declaration of a Holder
of shares of a series of AMPS differently than those of a Holder of shares of
any other series of AMPS without the affirmative vote of the holders of at least
a majority of the AMPS of each series adversely affected and outstanding at such
time (each such adversely affected series voting separately as a class). The
Trust shall notify Moody's and S&P ten Business Days prior to any such vote
described in clause

                                       38
<PAGE>
 
(i) or (ii). Unless a higher percentage is provided for under the Declaration,
the affirmative vote of the holders of a majority of the outstanding Preferred
Shares, including AMPS, voting together as a single class, will be required to
approve any plan of reorganization (including bankruptcy proceedings) adversely
affecting such shares or any action requiring a vote of security holders under
Section 13(a) of the 1940 Act. The class vote of holders of Preferred Shares,
including AMPS, described above will in each case be in addition to a separate
vote of the requisite percentage of shares of beneficial interest and Preferred
Shares, including AMPS, voting together as a single class necessary to authorize
the action in question.

     (d)   Voting Procedures.
           -----------------

     (i)    As soon as practicable after the accrual of any right of the holders
of Preferred Shares to elect additional trustees as described in paragraph 5(b)
above, the Trust shall call a special meeting of such holders and instruct the
Auction Agent to mail a notice of such special meeting to such holders, such
meeting to be held not less than 10 nor more than 20 days after the date of
mailing of such notice.  If the Trust fails to send such notice to the Auction
Agent or if the Trust does not call such a special meeting, it may be called by
any such holder on like notice.  The record date for determining the holders
entitled to notice of and to vote at such special meeting shall be the close of
business on the fifth Business Day preceding the day on which such notice is
mailed.  At any such special meeting and at each meeting held during a Voting
Period, such Holders, voting together as a class (to the exclusion of the
holders of all other securities and classes of shares of beneficial interest of
the Trust), shall be entitled to elect the number of trustees prescribed in
paragraph 5(b) above.  At any such meeting or adjournment thereof in the absence
of a quorum, a majority of such holders present in person or by proxy shall have
the power to adjourn the meeting without notice, other than by an announcement
at the meeting, to a date not more than 120 days after the original record date.

     (ii)  For purposes of determining any rights of the Holders to vote on any
matter or the number of shares required to constitute a quorum, whether such
right is created by this Certificate of Designation, by the other provisions of
the Declaration, by statute or otherwise, a share of AMPS which is not
Outstanding shall not be counted.

     (iii) The terms of office of all persons who are trustees of the Trust at
the time of a special meeting of Holders and holders of other Preferred Shares
to elect trustees shall continue,

                                       39
<PAGE>
 
notwithstanding the election at such meeting by the Holders and such other
holders of the number of trustees that they are entitled to elect, and the
persons so elected by the Holders and such other holders, together with the two
incumbent trustees elected by the Holders and such other holders of Preferred
Shares and the remaining incumbent trustees elected by the holders of the Common
Shares and Preferred Shares, shall constitute the duly elected trustees of the
Trust.

     (iv) Simultaneously with the expiration of a Voting Period, the terms of
office of the additional trustees elected by the Holders and holders of other
Preferred Shares pursuant to paragraph 5(b) above shall terminate, the remaining
trustees shall constitute the trustees of the Trust and the voting rights of the
Holders and such other holders to elect additional trustees pursuant to
paragraph 5(b) above shall cease, subject to the provisions of the last sentence
of paragraph 5(b).

     (e)  Exclusive Remedy. Unless otherwise required by law, the Holders of
          ----------------
AMPS shall not have any rights or preferences other than those specifically set
forth herein. The Holders of AMPS shall have no preemptive rights or rights to
cumulative voting. In the event that the Trust fails to pay any dividends on the
AMPS, the exclusive remedy of the Holders shall be the right to vote for
trustees pursuant to the provisions of this paragraph 5.

     (f)  Notification to S&P and Moody's. In the event a vote of Holders of
          -------------------------------
AMPS is required pursuant to the provisions of Section 13(a) of the 1940 Act,
the Trust shall, not later than ten Business Days prior to the date on which
such vote is to be taken, notify S&P and Moody's that such vote is to be taken
and the nature of the action with respect to which such vote is to be taken and,
not later than ten Business Days after the date on which such vote is taken,
notify S&P and Moody's of the result of such vote.

     6.   1940 Act AMPS Asset Coverage. The Trust shall maintain, as of the last
          ----------------------------
Business Day of each month in which any share of AMPS is outstanding, the 1940
Act AMPS Asset Coverage.

     7.   AMPS Basic Maintenance Amount. (a) The Trust shall maintain, on each
          -----------------------------
Valuation Date, and shall verify to its satisfaction that it is maintaining on
such Valuation Date, (i) S&P Eligible Assets having an aggregate Discounted
Value equal to or greater than the AMPS Basic Maintenance Amount and (ii)
Moody's Eligible Assets having an aggregate Discounted Value equal to or greater
than the AMPS Basic Maintenance Amount. Upon any

                                       40
<PAGE>
 
failure to maintain the required Discounted Value, the Trust will use its best
efforts to alter the composition of its portfolio to reattain a Discounted Value
at least equal to the AMPS Basic Maintenance Amount on or prior to the AMPS
Basic Maintenance Cure Date.

     (b) On or before 5:00 p.m., New York City time, on the third Business Day
after a Valuation Date on which the Trust fails to satisfy the AMPS Basic
Maintenance Amount, the Trust shall complete and deliver to the Auction gent,
and Moody's and S&P, as the case may be, a complete AMPS Basic Maintenance
Report as of the date of such failure, which will be deemed to have been
delivered to the Auction Agent if the Auction Agent receives a copy or telecopy,
telex or other electronic transcription thereof and on the same day the Trust
mails to the Auction Agent for delivery on the next Business Day the complete
AMPS Basic Maintenance Report. The Trust will deliver an AMPS Basic Maintenance
Report to the Auction Agent and Moody's and S&P, as the case may be, on or
before 5:00 p.m., New York City time, on the third Business Day after a
Valuation Date on which the Trust cures its failure to maintain Moody's Eligible
Assets or S&P Eligible Assets, as the case may be, with an aggregate Discounted
Value equal to or greater than the AMPS Basic Maintenance Amount or on which the
Trust fails to maintain Moody's Eligible Assets or S&P Eligible Assets, as the
case may be, with an aggregate Discounted Value which exceeds the AMPS Basic
Maintenance Amount by 5% or more. The Trust will also deliver an AMPS Basic
Maintenance Report to the Auction Agent, Moody's and S&P as of each Quarterly
Valuation Date on or before the third Business Day after such date.
Additionally, on or before 5:00 p.m., New York City time, on the third Business
Day after the first day of a Special Dividend Period, the Trust will deliver an
AMPS Basic Maintenance Report to S&P and the Auction Agent. The Trust shall also
provide Moody's and S&P with an AMPS Basic Maintenance Report when specifically
requested by either Moody's or S&P. A failure by the Trust to deliver an AMPS
Basic Maintenance Report under this paragraph 7(b) shall be deemed to be
delivery of an AMPS Basic Maintenance Report indicating the Discounted Value for
S&P Eligible Assets and Moody's Eligible Assets of the Trust is less than the
AMPS Basic Maintenance Amount, as of the relevant Valuation Date.

          (c) Within ten Business Days after the date of delivery of an AMPS
Basic Maintenance Report in accordance with paragraph 7(b) above relating to a
Quarterly Valuation Date, the Independent Accountant will confirm in writing to
the Auction Agent, S&P and Moody's (i) the mathematical accuracy of the
calculations reflected in such Report (and in any other AMPS

                                       41
<PAGE>
 
Basic Maintenance Report, randomly selected by the Independent Accountant, that
was delivered by the Trust during the quarter ending on such Quarterly Valuation
Date), (ii) that, in such Report (and in such randomly selected Report), the
Trust correctly determined the assets of the Trust which constitute S&P Eligible
Assets or Moody's Eligible Assets, as the case may be, at such Quarterly
Valuation Date in accordance with this Certificate of Designation, (iii) that,
in such Report (and in such randomly selected Report), the Trust determined
whether the Trust had, at such Quarterly Valuation Date (and at the Valuation
Date addressed in such randomly selected Report) in accordance with this
Certificate of Designation, S&P Eligible Assets of an aggregate Discounted Value
at least equal to the AMPS Basic Maintenance Amount and Moody's Eligible Assets
of an aggregate Discounted Value at least equal to the AMPS Basic Maintenance
Amount, (iv) with respect to the S&P ratings on Florida Municipal Bonds or
Municipal Bonds, the issuer name, issue size and coupon rate listed in such
Report, that the Independent Accountant has requested that S&P verify such
information and the Independent Accountant shall provide a listing in its letter
of any differences, (v) with respect to the Moody's ratings on Florida Municipal
Bonds or Municipal Bonds, the issuer name, issue size and coupon rate listed in
such Report, that such information has been verified by Moody's (in the event
such information is not verified by Moody's, the Independent Accountant will
inquire of Moody's what such information is, and provide a listing in its letter
of any differences), (vi) with respect to the bid or mean price (or such
alternative permissible factor used in calculating the Market Value) provided by
the custodian of the Trust's assets to the Trust for purposes of valuing
securities in the Trust's portfolio, the Independent Accountant has traced the
price used in such Report to the bid or mean price listed in such Report as
provided to the Trust and verified that such information agrees (in the event
such information does not agree, the Independent Accountant will provide a
listing in its letter of such differences) and (vii) with respect to such
confirmation to Moody's, that the Trust has satisfied the requirements of
paragraph 8(b) of this Certificate of Designation (such confirmation is herein
called the "Accountant's Confirmation") .

          (d) Within ten Business Days after the date of delivery to the Auction
Agent, S&P and Moody's of an AMPS Basic Maintenance Report in accordance ith
paragraph 7(b) above relating to any Valuation Date on which the Trust failed to
maintain S&P Eligible Assets with an aggregate Discounted Value and Moody's
Eligible Assets with an aggregate Discounted Value equal to or greater than the
AMPS Basic Maintenance Amount, and relating to the AMPS Basic

                                       42
<PAGE>
 
Maintenance Cure Date with respect to such failure, the Independent Accountant
will provide to the Auction Agent, S&P and Moody's an Accountant's Confirmation
as to such AMPS Basic Maintenance Report.

     (e) If any Accountant's Confirmation delivered pursuant to subparagraph (c)
or (d) of this paragraph 7 shows that an error was made in the AMPS Basic
Maintenance Report for a particular Valuation Date for which such Accountant's
Confirmation as required to be delivered, or shows that a lower aggregate
Discounted Value for the aggregate of all S&P Eligible Assets or Moody's
Eligible Assets, as the case may be, of the Trust was determined by the
Independent Accountant, the calculation or determination made by such
Independent Accountant shall be final and conclusive and shall be binding on the
Trust, and the Trust shall accordingly amend and deliver the AMPS Basic
Maintenance Report to the Auction Agent, S&P and Moody's promptly following
receipt by the Trust of such Accountant's Confirmation.

     (f) On or before 5:00 p.m., New York City time, on the first Business Day
after the Date of Original Issue of the AMPS, the Trust will complete and
deliver to S&P and Moody's an AMPS Basic Maintenance Report as of the close of
business on such Date of Original Issue. Within five Business Days of such Date
of Original Issue, the Independent Accountant will confirm in writing to S&P and
Moody's (i) the mathematical accuracy of the calculations reflected in such
Report and (ii) that the aggregate Discounted Value of S&P Eligible Assets and
the aggregate Discounted Value of Moody's Eligible Assets reflected thereon
equals or exceeds the AMPS Basic Maintenance Amount reflected thereon. Also, on
or before 5:00 p.m., New York City time, on the first Business Day after Common
Shares are repurchased by the Trust, the Trust will complete and deliver to S&P
and Moody's an AMPS Basic Maintenance Report as of the close of business on such
date that Common Shares are repurchased.

     (g) For so long as AMPS are rated by Moody's, in managing the Trust's
portfolio, the Adviser will not alter the composition of the Trust's portfolio
if, in the reasonable belief of the Adviser, the effect of any such alteration
would be to cause the Trust to have Moody's Eligible Assets with an aggregate
Discounted Value, as of the immediately preceding Valuation Date, less than the
AMPS Basic Maintenance Amount as of such Valuation Date; provided, however, that
in the event that, as of the immediately preceding Valuation Date, the aggregate
Discounted Value of Moody's Eligible Assets exceeded the AMPS Basic Maintenance
Amount by five

                                       43
<PAGE>
 
percent or less, the Adviser will not alter the composition of the Trust's
portfolio in a manner reasonably expected to reduce the aggregate Discounted
Value of Moody's Eligible Assets unless the Trust shall have confirmed that,
after giving effect to such alteration, the aggregate Discounted Value of
Moody's Eligible Assets would exceed the AMPS Basic Maintenance Amount.

     8.   Certain Other Restrictions and Requirements. (a) For so long as any
          ------------------------------------------- 
AMPS are rated by S&P, the Trust will not purchase or sell futures contracts,
write, purchase or sell options on futures contracts or write put options
(except covered put options) or call options (except covered call options) on
portfolio securities unless it receives written confirmation from S&P that
engaging in such transactions will not impair the ratings then assigned to the
AMPS by S&P, except that the Trust may purchase or sell futures contracts based
on the Bond Buyer Municipal Bond Index (the "Municipal Index") or United States
Treasury Bonds or Notes ("Treasury Bonds") and write, purchase or sell put and
call options on such contracts (collectively, "S&P Hedging Transactions"),
subject to the following limitations:

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

     --------------
          
          (ii)  the Trust will not engage in any S&P Hedging Transaction based
     on Treasury Bonds (other than Closing Transactions) which would cause the
     Trust at the time of such transaction to own or have sold the lesser of (A)
     outstanding futures contracts based on Treasury Bonds exceeding in number
     50% of the quotient of the Market Value of the Trust's total assets divided
     by $100,000 ($200,000 in the case of the

     Street Journal;
     ---------------

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

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

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

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

or sell futures contracts, write, purchase or sell call options on futures
contracts or purchase put options on futures contracts or write call options
(except covered call options) on portfolio securities unless it receives written
confirmation from Moody's that engaging in such transactions would not impair
the ratings then assigned to the AMPS by Moody's, except that the Trust may
purchase or sell exchange-traded futures contracts based on the Municipal Index
or Treasury Bonds and purchase, write or sell exchange-traded put options on
such futures contracts and purchase, write or sell exchange-traded call options
on such futures contracts (collectively, "Moody's Hedging Transactions"),
subject to the following limitations :

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

          (ii)  the Trust will not engage in any Moody's Hedging Transaction
     based on Treasury Bonds (other than Closing Transactions) which would cause

     Market Value exceeding 20% of the aggregate Market Value of Moody's
     Eligible Assets owned by the Trust and rated Aa by Moody's (or, if not

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

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

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

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

     For purposes of determining whether the Trust has Moody's Eligible Assets
with an aggregate Discounted Value that equals or exceeds the AMPS Basic
Maintenance Amount, the Discounted Value of Moody's Eligible Assets which the
Trust is obligated to deliver or receive pursuant to an outstanding futures
contract or option shall be as follows:  (i) assets subject to call options
written by the Trust which are either exchange-traded and "readily reversible"
or which expire within 49 days after the date as of which such valuation is made
shall be valued at the lesser of (a) Discounted Value and (b) the exercise price
of the call option written by the Trust; (ii) assets subject to call options
written by the Trust not meeting the requirements of clause

                                       47
<PAGE>
 
(i) of this sentence shall have no value; (iii) assets subject to put options
written by the Trust shall be valued at the lesser of (A) the exercise price and
(B) the Discounted Value of the subject security; (iv) futures contracts shall
be valued at the lesser of (A) settlement price and (B) the Discounted Value of
the subject security, provided that, if a contract matures within 49 days after
the date as of which such valuation is made, where the Trust is the seller the
contract may be valued at the settlement price and where the Trust is the buyer
the contract may be valued at the Discounted Value of the subject securities;
and (v) where delivery may be made to the Trust with any security of a class of
securities, the Trust shall assume that it will take delivery of the security
with the lowest Discounted Value.

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

          (c) For so long as any AMPS are rated by Moody's, the Trust will not
enter into any contract to purchase securities for a fixed price at a future
date beyond customary settlement time (other than such contracts that constitute
Moody's Hedging Transactions that are permitted under paragraph 8(b) of this
Certificate of Designation), except that the Trust may enter into such contracts
to purchase newly-issued securities on the date such securities are issued
("Forward Commitments"), subject to the following limitations :

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

                                       48
<PAGE>
 
     securities with a Discounted Value that equals or exceeds the amount of the
     Trust's obligations under any Forward Commitment to which it is from time
     to time a party; and

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

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

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

          9.    Notice. All notices or communications, unless otherwise
                ------
specified in the By-Laws of the Trust or this Certificate of Designation, shall
be sufficiently given if in writing and delivered in person or mailed by first-
class mail, postage prepaid. Notice shall be deemed given on the earlier of the
date received or the date seven days after which such notice is mailed.

          be the Applicable Percentage of the Reference Rate. The Applicable
          Percentage will be determined based on (i) the lower of the credit

          Substitute Rating Agency or two Substitute Rating Agencies or, in the
          event that only one such rating shall be available, such rating) and
          (ii) whether the Trust has provided notification to the Auction Agent

     The Trust shall take all reasonable action necessary to enable S&P and
Moody's to provide a rating for each series of the AMPS.  If either S&P or
Moody's shall not make such a rating available, or neither S&P nor Moody's shall
make such a rating available, Merrill Lynch, Pierce, Fenner & Smith Incorporated
or its affiliates and successors, after consultation with the Trust, shall
select a nationally recognized statistical rating organization or two nationally
recognized statistical rating organizations to act as a Substitute Rating Agency
or Substitute Rating Agencies, as the case may be.

     (b)  Orders by Beneficial Owners, Potential Beneficial Owners, Existing
          ------------------------------------------------------------------
Holders and Potential Holders.
- -----------------------------

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

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

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

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

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

                                       52
<PAGE>
 
          (B) each Broker-Dealer, using a list of Potential Beneficial Owners
     that shall be maintained in good faith for the purpose of conducting a
     competitive Auction, shall contact Potential Beneficial Owners, including
     Persons that are not Beneficial Owners, on such list to determine the
     number of Outstanding shares, if any, of AMPS which each such Potential
     Beneficial Owner offers to purchase, provided that the Applicable Rate for
     the next succeeding Dividend Period shall not be less than the rate per
     annum specified by such Potential Beneficial Owner.

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

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

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

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

                                       53
<PAGE>
 
                    (3) a lesser number of Outstanding AMPS to be determined as
               set forth in paragraph 10(e)(ii)(C) if such specified rate per
               annum shall be higher than the Maximum Applicable Rate and
               Sufficient Clearing Bids do not exist.

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

                    (1) the number of Outstanding AMPS specified in such Sell
               Order; or

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

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

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

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

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

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

                                       54
<PAGE>
 
          (A)   the name of the Bidder placing such Order (which shall be the
     Broker-Dealer unless otherwise permitted by the Trust);

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

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

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

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

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

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

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

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

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

                                       55
<PAGE>
 
          (A)  any Hold Order submitted on behalf of such Existing Holder shall
     be considered valid up to and including the number of Outstanding AMPS held
     by such Existing Holder; provided that if more than one Hold Order is
     submitted on behalf of such Existing Holder and the number of AMPS subject
     to such Hold Orders exceeds the number of Outstanding AMPS held by such
     Existing Holder, the number of AMPS subject to each of such Hold Orders
     shall be reduced pro rata so that such Hold Orders, in the aggregate, will
     cover exactly the number of Outstanding AMPS held by such Existing Holder;

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

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

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

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

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

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

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

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

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

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

                                       57
<PAGE>
 
          (C)  if Sufficient Clearing Bids exist, the lowest rate per annum
     specified in the Submitted Bids (the "Winning Bid Rate") that if:

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

               (2)  each Submitted Bid from Potential Holders specifying the
          Winning Bid Rate and all other Submitted Bids from Potential Holders
          specifying lower rates per annum were accepted, thus entitling the
          Potential Holders to purchase the AMPS that are the subject of such
          Submitted Bids, would result in the number of shares subject to all
          Submitted Bids specifying the Winning Bid Rate or a lower rate per
          annum being at least equal to the Available AMPS.

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

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

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

          (C)  if all of the Outstanding AMPS are the subject of Submitted Hold
     Orders, that the Dividend Period next succeeding the Auction shall
     automatically be the same length as the immediately preceding Dividend
     Period and the Applicable Rate for the next succeeding Dividend Period
     shall be equal to 40% of the Reference Rate (or 60% of such rate if the
     Trust has provided notification to the Auction Agent prior to the Auction
     establishing the Applicable Rate for any dividend pursuant to paragraph
     2(f) hereof that 

                                       58
<PAGE>
 
     net capital gains or other taxable income will be included in such dividend
     on AMPS) on the date of the Auction.

     (e) Acceptance and Rejection of Submitted Bids and Submitted Sell Orders
         --------------------------------------------------------------------
and Allocation of Shares. Based on the determinations made pursuant to paragraph
- ------------------------
10(d)(i), the Submitted Bids and Submitted Sell Orders shall be accepted or
rejected and the Auction Agent shall take such other action as set forth below:

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

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

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

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

          (D)  the Submitted Bid of each of the Existing Holders specifying a
     rate per annum that is equal to the Winning Bid Rate shall be rejected,
     thus entitling each such Existing Holder to continue to hold the
     Outstanding AMPS that are the subject of such Submitted Bid, unless the
     number of Outstanding AMPS subject to all such Submitted Bids shall be
     greater than the number of Outstanding AMPS ("Remaining Shares") equal to
     the excess of the Available AMPS over the number of Outstanding AMPS
     subject to Submitted Bids described in paragraph 10(e)(i)(B) and paragraph
     10(e)(i)(C), in which event the Submitted Bids of each such Existing Holder
     shall be accepted, and each such 

                                       59
<PAGE>
 
     Existing Holder shall be required to sell Outstanding AMPS, but only in an
     amount equal to the difference between (1) the number of Outstanding AMPS
     then held by such Existing Holder subject to such Submitted Bid and (2) the
     number of AMPS obtained by multiplying (x) the number of Remaining Shares
     by (y) a fraction the numerator of which shall be the number of Outstanding
     AMPS held by such Existing Holder subject to such Submitted Bid and the
     denominator of which shall be the sum of the number of Outstanding AMPS
     subject to such Submitted Bids made by all such Existing Holders that
     specified a rate per annum equal to the Winning Bid Rate; and

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

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

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

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

                                       60
<PAGE>
 
          (C)   the Submitted Bids of each Existing Holder specifying any rate
     per annum that is higher than the Maximum Applicable Rate shall be accepted
     and the Submitted Sell Orders of each Existing Holder shall be accepted, in
     both cases only in an amount equal to the difference between (1) the number
     of Outstanding AMPS then held by such Existing Holder subject to such
     Submitted Bid or Submitted Sell Order and (2) the number of AMPS obtained
     by multiplying (x) the difference between the Available AMPS and the
     aggregate number of Outstanding AMPS subject to Submitted Bids described in
     paragraph 10(e)(ii)(A) and paragraph 10(e)(ii)(B) by (y) a fraction the
     numerator of which shall be the number of Outstanding AMPS held by such
     Existing Holder subject to such Submitted Bid or Submitted Sell Order and
     the denominator of which shall be the number of Outstanding AMPS subject to
     all such Submitted Bids and Submitted Sell Orders.

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

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

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

                                       61
<PAGE>
 
     purchased and the aggregate number of the Outstanding AMPS to be sold by
     such Potential Holders and Existing Holders and, to the extent that such
     aggregate number of Outstanding shares to be purchased and such aggregate
     number of Outstanding shares to be sold differ, the Auction Agent shall
     determine to which other Broker-Dealer or Broker-Dealers acting for one or
     more purchasers such Broker-Dealer shall deliver, or from which other
     Broker-Dealer or Broker-Dealers acting for one or more sellers such Broker-
     Dealer shall receive, as the case may be, Outstanding AMPS.

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

     11.  Securities Depository; Share Certificates. (a) If there is a
          -----------------------------------------    
Securities Depository, one certificate for all of the AMPS of each series shall
be issued to the Securities Depository and registered in the name of the
Securities Depository or its nominee. Additional certificates may be issued as
necessary to represent AMPS. All such certificates shall bear a legend to the
effect

                                       62
<PAGE>
 
that such certificates are issued subject to the provisions restricting the
transfer of AMPS contained in this Certificate of Designation. Unless the Trust
shall have elected, during a Non-Payment Period, to waive this requirement, the
Trust will also issue stop-transfer instructions to the Auction Agent for the
AMPS. Except as provided in paragraph (b) below, the Securities Depository or
its nominee will be the Holder, and no Beneficial Owner shall receive
certificates representing its ownership interest in such shares.

     (b)  If the Applicable Rate applicable to all AMPS of a series shall be the
Non-Payment Period Rate or there is no Securities Depository, the Trust may at
its option issue one or more new certificates with respect to such shares
(without the legend referred to in paragraph 11(a)) registered in the names of
the Beneficial Owners or their nominees and rescind the stop-transfer
instructions referred to in paragraph 11(a) with respect to such shares.

     12.   Personal Liability. The Declaration of Trust establishing
           ------------------                                    
MuniHoldings Florida Insured Fund IV, dated         , 1998, a copy of which,
together with all amendments thereto, is on file in the office of the Secretary

satisfaction of any obligation or claim or otherwise in connection with the
affairs of the Trust, but the "Trust Property" only shall be liable.

     trust, loan or credit agreement, note, lease or other agreement or
     instrument to which the Fund is a party or by which it or its properties
     may be bound, or to which any of the property or assets of the Fund is
     subject (collectively, "Agreements and Instruments"), except for such
     defaults that would not result in a Material Adverse Effect; and the
     execution, delivery and performance of this Agreement, the Investment
     Advisory Agreement, the Custody Agreement, the Auction Agent Agreement and
     the Letter of Representations referred to in the Registration Statement (as
     used herein, the "Advisory Agreement", the "Custody Agreement," the
     "Auction Agreement" and the "Letter of Representations" respectively) and
     the consummation of the transactions contemplated in this Agreement and in
     the Registration Statement (including the issuance and sale of the Shares
     and the use of the proceeds from the sale of the Shares as described in the
     Prospectus under the caption "Use of Proceeds") and compliance by the Fund
     with its obligations under this Agreement have been duly authorized by all
     necessary corporate action and do not and will not, whether with or without
     the giving of notice or passage of time or both, conflict with or
     constitute a breach of, or a default or Repayment Event (as defined below)
     under, or result in the creation or imposition of any lien, charge or
     encumbrance upon any property or assets of the Fund pursuant to the
     Agreements and Instruments (except for such conflicts, breaches or defaults
     or liens, charges or encumbrances that would not result in a Material
     Adverse Effect), nor will such action result in any violation of the

     right to require the repurchase, redemption or repayment of all or a
     portion of such indebtedness by the Fund.

     Advisory Agreement and the Custody Agreement has been duly authorized,
     executed and delivered by the Fund, and each complies with all applicable
     provisions of the Investment Company Act. Each of the Auction Agreement and
     the Letter of Representations has been duly authorized for execution and
     delivery by the Fund and, when executed and delivered by the Fund, will
     constitute a valid and binding obligation of the Fund, enforceable in
     accordance with its terms, subject, as to enforcement, to bankruptcy,
     insolvency, reorganization or other laws relating to or affecting
     creditors' rights and to general equitable principles.

          (xiv)  Absence of Proceedings.  There is no action, suit, proceeding,
                 ----------------------                                      
     inquiry or investigation before or brought by any court or governmental
     agency or body, domestic or foreign, now pending, or, to the knowledge of
     the Fund, threatened against or affecting the Fund, which is required to be
     disclosed in the Registration Statement (other than as disclosed therein),
     or which might reasonably be expected to result in a Material Adverse
     Effect, or which might reasonably be expected to materially and adversely
     affect the properties or assets thereof or the consummation of the
     transactions contemplated in this Agreement or the performance by the Fund
     of its obligations hereunder; the aggregate of all pending legal or
     governmental proceedings to which the Fund is a party or of which any of
     its respective property or assets is the subject which are not described in
     the Registration Statement, including ordinary routine litigation
     incidental to the business, could not reasonably be expected to result in a
     Material Adverse Effect.

                 -----------------------                                  
     direct the investment of the proceeds of the offering described in the
     Registration Statement in such a manner as to comply with the requirements
     of Subchapter M of the Code, and intends to qualify as a regulated
     investment company under Subchapter M of the Code.

          (xvi)  Accuracy of Exhibits.  There are no contracts or documents 
                 --------------------                                       
     which are required to be described in the Registration Statement or the
     Prospectus or to be filed as exhibits thereto which have not been so
     described and filed as required.

          (xvii) Possession of Intellectual Property.  The Fund owns or 
                 -----------------------------------                    
     possesses, or can acquire on reasonable terms, adequate patents, patent
     rights, licenses, inventions, copyrights, know-how (including trade secrets
     and other unpatented and/or unpatentable proprietary or confidential
     information, systems or procedures), trademarks, service marks, trade names
     or other intellectual property (collectively, "Intellectual Property")
     necessary to carry on the business now operated by it, and the Fund has not
     received any notice or is otherwise aware of any infringement or conflict
     with asserted rights of others with respect to any Intellectual Property or
     of any facts or circumstances which would render any Intellectual Property
     invalid or inadequate to protect the interest of the Fund 

                                       6
<PAGE>
 
     therein, and which infringement or conflict (if the subject of any
     unfavorable decision, ruling or finding) or invalidity or inadequacy,
     singly or in the aggregate, would result in a Material Adverse Effect.

          (xviii) Absence of Further Requirements.  No filing with, or 
                  -------------------------------                      
     authorization, approval, consent, license, order, registration,
     qualification or decree of, any court or governmental authority or agency
     is necessary or required for the performance by the Fund of its obligations
     hereunder, in connection with the offering, issuance or sale of the Shares
     under this Agreement or the consummation of the transactions contemplated
     by this Agreement, except such as have been already obtained or as may be
     required under the 1933 Act or the 1940 Act or the Rules and Regulations
     and foreign or state securities or blue sky laws.

          (xix)   Possession of Licenses and Permits.  The Fund possesses such 
                  ----------------------------------                          
     permits, licenses, approvals, consents and other authorizations
     (collectively, "Governmental Licenses") issued by the appropriate federal,
     state, local or foreign regulatory agencies or bodies necessary to conduct
     the business now operated by it; the Fund is in compliance with the terms
     and conditions of all such Governmental Licenses, except where the failure
     so to comply would not, singly or in the aggregate, have a Material Adverse
     Effect; all of the Governmental Licenses are valid and in full force and
     effect, except when the invalidity of such Governmental Licenses or the
     failure of such Governmental Licenses to be in full force and effect would
     not have a Material Adverse Effect; and the Fund has not received any
     notice of proceedings relating to the revocation or modification of any
     such Governmental Licenses which, singly or in the aggregate, if the
     subject of an unfavorable decision, ruling or finding, would result in a
     Material Adverse Effect.

     possible moment. The Fund will promptly effect the filings necessary
     pursuant to Rule 497(c), Rule 497(j) or Rule 497(h) and will take such
     steps as it deems necessary to ascertain promptly whether the certificate
     transmitted for filing under Rule 497(j) or the form of prospectus and
     statement of additional information transmitted for filing under Rule
     497(c) or Rule 497(h) was received for filing by the Commission and, in the
     event that it was not, it will promptly file such certificate or prospectus
     and statement of additional information.

          (b)  Filing of Amendments. The Fund will give the Underwriter notice
     of its intention to file or prepare any amendment to the Registration

     the prospectus or statement of additional information included in the
     Registration Statement at the time it became effective or to the
     Prospectus, whether pursuant to the Investment Company Act, the 1933 Act,
     or otherwise, and will furnish the Underwriter with copies of any such
     documents a reasonable amount of time prior to such proposed filing or use,
     as the case may be, and will not file or use any such document to which the
     Underwriter or counsel to the Underwriter and the Fund shall object.

          (c)  Delivery of Registration Statements. The Fund has furnished or
     will deliver to the Underwriter and counsel to the Underwriter and the
     Fund, without charge, signed copies of the notification of registration on

     amendment thereto, (including exhibits filed therewith, or incorporated by
     reference therein) and signed copies of all consents and certificates of
     experts, and will also deliver to the Underwriter a conformed copy, without
     charge, of the Registration Statement as originally filed and of each
     amendment thereto (without exhibits) for the Underwriter. The copies of the

     permitted by Regulation S-T.

          (d)  Delivery of Prospectus. The Fund has delivered to the
     Underwriter, without charge, as many copies of each preliminary

                                       9
<PAGE>
 
     1933 Act. The Fund will furnish to the Underwriter, without charge, during
     the period when the Prospectus is required to be delivered under the 1933
     Act, such number of copies of the Prospectus (as amended or supplemented)
     as the Underwriter may reasonably request. The Prospectus and any

     prospectus is required by the 1933 Act to be delivered in connection with
     sales of the Shares, any event shall occur or condition shall exist as a
     result of which it is necessary, in the opinion of counsel to the
     Underwriter and the Fund, to amend the Registration Statement or amend or
     supplement any Prospectus in order that the Prospectus will not include any
     untrue statements of material fact or omit to state a material fact
     necessary in order to make the statements therein not misleading in the
     light of the circumstances existing at the time it is delivered to a
     purchaser, or if it shall be necessary, in the opinion of such counsel, at
     any such time to amend the Registration Statement or amend or supplement
     any Prospectus in order to comply with the requirements of the 1933 Act or
     the 1933 Act Regulations, the Fund will promptly prepare and file with the
     Commission, subject to Section 3(b), such amendment or supplement as may be
     necessary to correct such statement or omission or to make the Registration
     Statement or the Prospectus comply with such requirements, and the Fund
     will furnish to the Underwriter such number of copies of such amendment or
     supplement as the Underwriter may reasonably request.

          (f)  Blue Sky Qualifications.   The Fund will use its best efforts, in
     cooperation with the Underwriter, to qualify the Shares for offering and
     sale under the applicable securities laws of such states and other
     jurisdictions as the Underwriter may designate and to maintain such
     qualifications in effect for a period of not less than one year from the
     later of the effective date of the Registration Statement and any Rule
     462(b) Registration Statement; provided, however, that the Fund shall not
     be obligated to file any general consent to service of process or to
     qualify as a dealer in securities in any jurisdiction in which it is not so
     qualified or to subject itself to taxation in respect of doing business in
     any jurisdiction in which it is not otherwise so subject.  In each
     jurisdiction in which the Shares have been so qualified, the Fund will file
     such statements and reports as may be required by the laws of such
     jurisdiction to continue such qualification in effect for a period of not
     less than one year from the effective date of the Registration Statement
     and any Rule 462(b) Registration Statement.

          (g)  Rule 158. The Fund will timely file such reports pursuant to the
     Investment Company Act as are necessary in order to make generally
     available to its securityholders as soon as practicable an earnings
     statement for the purposes of, and to provide the benefits contemplated by,
     the last paragraph of Section 11(a) of the 1933 Act.

          (h)  Use of Proceeds. The Fund will use the net proceeds received by
     it from the sale of the Shares in the manner specified in the Prospectus
     under "Use of Proceeds."

                                       10

     (i)  Subchapter M.  The Fund will use its best efforts to maintain its
qualification as a regulated investment company under Subchapter M of the Code.

directly or indirectly (i) offer, pledge, sell, contract to sell, sell any

transaction that transfers, in whole or in part, directly or indirectly, the
economic consequence of ownership of senior securities, whether any such swap or
transaction described in clause (i) or (ii) above is to be settled by delivery

apply to (A) the Shares to be sold hereunder or (B) transactions as contemplated
in the Registration Statement where the Fund has segregated cash, cash
equivalents or liquid securities at the Fund's custodian having a market value
at all times at least equal to the amount of such senior securities.

     SECTION 7.   Indemnification.
                  --------------- 
     (a)  Indemnification of the Underwriter.   (1) The Fund and the Adviser
jointly and severally agree to indemnify and hold harmless the Underwriter and
each person, if any, who controls the Underwriter within the meaning of Section
15 of the 1933 Act as follows:

          (i)    against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto), including the Rule 430A Information and the
     Rule 434 Information, if applicable, or the omission or alleged omission
     therefrom of a material fact required to be stated therein or necessary to
     make the statements therein not misleading or arising out of any untrue
     statement or alleged untrue statement of a material fact included in any
     preliminary prospectus/statement or the Prospectus (or any amendment or
     supplement thereto), or the omission or alleged omission therefrom of a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

          (ii)   against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, provided that
     (subject to Section 7(d) below) any such settlement is effected with the
     written consent of the indemnifying party; and

          (iii)  against any and all expense whatsoever, as incurred (including
     the fees and disbursements of counsel chosen by the Underwriter) reasonably
     incurred in investigating, preparing or defending against any litigation,
     or any investigation or proceeding by any governmental agency or body,
     commenced or threatened, or any claim whatsoever based upon any such untrue
     statement or omission, or any such alleged untrue statement or omission, to
     the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
- --------  -------                                                            
liability, claim, damage or expense to the extent arising out of any untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished to the Fund by the
Underwriter expressly for use in the Registration Statement (or any amendment
thereto), including the Rule 430A Information and the Rule 434 Information, if
applicable, or any preliminary prospectus/statement or the Prospectus (or any
amendment or supplement thereto).

     (2)  Insofar as this indemnity agreement may permit indemnification for
liabilities under the 1933 Act of any person who is a partner of the Underwriter
or who controls the Underwriter within the meaning of Section 15 of the 1933 Act
and who, at the date of this Agreement, is a trustee or officer of the Fund or
controls the Fund within the meaning of Section 

                                       14
<PAGE>
 
15 of the 1933 Act, such indemnity agreement is subject to the undertaking of
the Fund in the Registration Statement under Item 29 thereof.

     (b)  Indemnification of Fund, Adviser, Trustees, General Partner and
Officers.   The Underwriter agrees to indemnify and hold harmless the Fund, the
Adviser, the trustees of the Fund, the general partner of the Adviser, each of
the Fund's officers who signed the Registration Statement, and each person, if
any, who controls the Fund or the Adviser within the meaning of Section 15 of
the 1933 Act, against any and all loss, liability, claim, damage and expense
described in the indemnity contained in subsection (a) of this Section, as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) including the Rule 430A Information and the Rule 434
Information, if applicable, or in any preliminary prospectus/statement or the
Prospectus (or any amendment or supplement thereto) in reliance upon and in
conformity with written information furnished to the Fund by the Underwriter
expressly for use in the Registration Statement (or any amendment thereto), or
any preliminary prospectus/statement or the Prospectus (or any amendment or
supplement thereto).

     (c)  Actions against Parties, Notification.   Each indemnified party shall
give notice as promptly as reasonably practicable to each indemnifying party of
any action commenced against it in respect of which indemnity may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying party from any liability hereunder to the extent it is not
materially prejudiced as a result thereof and in any event shall not relieve it
from any liability which it may have otherwise than on account of this indemnity
agreement. In the case of parties indemnified pursuant to Section 7(a) above,
counsel to the indemnified parties shall be selected by the Underwriter, and, in
the case of parties indemnified pursuant to Section 7(b) above, counsel to the
indemnified parties shall be selected by the Fund and the Adviser. An
indemnifying party may participate at its own expense in the defense of any such
action; provided, however, that counsel to the indemnifying party shall not
(except with the consent of the indemnified party) also be counsel to the
indemnified party. In no event shall the indemnifying parties be liable for the
fees and expenses of more than one counsel (in addition to any local counsel)
separate from their own counsel for all indemnified parties in connection with
any one action or separate but similar or related actions in the same
jurisdiction arising out of the same general allegations or circumstances. No
indemnifying party shall, without the prior written consent of the indemnified
parties, settle or compromise or consent to the entry of any judgment with
respect to any litigation, or any investigation or proceeding by any
governmental agency or body, commenced or threatened, or any claim whatsoever in
respect of which indemnification or contribution could be sought under this
Section 7 or Section 8 hereof (whether or not the indemnified parties are actual
or potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional release of each indemnified party from all liability
arising out of such litigation, investigation, proceeding or claim and (ii) does
not include a statement as to or an admission of fault, culpability or a failure
to act by or on behalf of any indemnified party.

     (d)  Settlement without Consent if Failure to Reimburse.  If at any time an
indemnified party shall have requested an indemnifying party to reimburse the
indemnified party for fees and expenses of counsel, such indemnifying party
agrees that it shall be liable for any settlement of the nature contemplated by
Section 7 (a)(ii) effected without its written consent if 

                                       15
<PAGE>
 
(i) such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
have received notice of the terms of such settlement at least 30 days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement.

     SECTION 8.   Contribution.  If the indemnification provided for in Section
                  ------------   
7 hereof is for any reason unavailable to or insufficient to hold harmless an
indemnified party in respect of any losses, liabilities, claims, damages or
expenses referred to therein, then each indemnifying party shall contribute to
the aggregate amount of such losses, liabilities, claims, damages and expenses
incurred by such indemnified party, as incurred, (i) in such proportion as is
appropriate to reflect the relative benefits received by the Fund and the
Adviser on the one hand and the Underwriter on the other hand from the offering
of the Shares pursuant to this Agreement or (ii) if the allocation provided by
clause (i) is not permitted by applicable law, in such proportion as is
appropriate to reflect not only the relative benefits referred to in clause (i)
above but also the relative fault of the Fund and the Adviser on the one hand
and of the Underwriter on the other hand in connection with the statements or
omissions which resulted in such losses, liabilities, claims, damages or
expenses, as well as any other relevant equitable considerations.

     The relative benefits received by the Fund and the Adviser on the one hand
and the Underwriter on the other hand in connection with the offering of the
Shares pursuant to this Agreement shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Shares pursuant
to this Agreement (net of underwriting discounts and commissions but before
deducting expenses) received by the Fund, and the total underwriting discount
received by the Underwriter, in each case as set forth on the cover of the
Prospectus, or, if Rule 434 is used, the corresponding location on the Term
Sheet, bear to the aggregate initial public offering price of the Shares as set
forth on such cover.

     The relative fault of the Fund and the Adviser on the one hand and the
Underwriter on the other hand shall be determined by reference to, among other
things, whether any such untrue or alleged untrue statement of a material fact
or omission or alleged omission to state a material fact relates to information
supplied by the Fund and the Adviser or by the Underwriter and the parties'
relative intent, knowledge, access to information and opportunity to correct or
prevent such statement or omission.

     The Fund, the Adviser and the Underwriter agree that it would not be just
and equitable if contribution pursuant to this Section 8 were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 8.  The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 8 shall be deemed
to include any legal or other expenses reasonably incurred by such indemnified
party in investigating, preparing or defending against any litigation, or any
investigation or proceeding by any governmental agency or body, commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 8, the Underwriter shall not
be required to contribute any amount in excess of the amount by which the total
price at which the Shares 

                                       16
<PAGE>
 
underwritten by it and distributed to the public were offered to the public
exceeds the amount of any damages which the Underwriter has otherwise been
required to pay by reason of any such untrue or alleged untrue statement or
omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 8, each person, if any, who controls the
Underwriter within the meaning of Section 15 of the 1933 Act shall have the same
rights to contribution as the Underwriter, and each director of the Fund and the
Adviser, respectively, each officer of the Fund who signed the Registration
Statement and each person, if any, who controls the Fund and the Adviser within
the meaning of Section 15 of the 1933 Act, shall have the same rights to
contribution as the Fund and the Adviser.

     SECTION 9.  Representations, Warranties and Agreements to Survive Delivery.
                 -------------------------------------------------------------- 
All representations, warranties and agreements contained in this Agreement or in
certificates of officers of the Fund or of the Adviser submitted pursuant
hereto, shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Underwriter or controlling person, or
by or on behalf of the Fund or the Adviser and shall survive delivery of the
Shares to the Underwriter.

     SECTION 10. Termination of Agreement.
                 ------------------------ 

     (a)  Termination; General.  The Underwriter may terminate this Agreement by
notice to the Fund, at any time at or prior to Closing Time (i) if there has
been, since the time of execution of this Agreement or since the respective
dates as of which information is given in the Prospectus, any material adverse
change in the condition, financial or otherwise, or in the earnings, business
affairs or business prospects of the Fund or the Adviser, whether or not arising
in the ordinary course of business, or (ii) if there has occurred any material
adverse change in the financial markets in the United States or the
international financial markets, any outbreak of hostilities or escalation
thereof or other calamity or crisis or any change or development involving a
prospective change in national or international political, financial or economic
conditions, in each case the effect of which is such as to make it, in the
judgment of the Underwriter, impracticable to market the Shares or to enforce
contracts for the sale of the Shares, or (iii) if trading in any securities of
the Fund has been suspended or materially limited by the Commission or the New
York Stock Exchange, or if trading generally on the American Stock Exchange or
the New York Stock Exchange or in the Nasdaq National Market has been suspended
or materially limited, or minimum or maximum prices for trading have been fixed,
or maximum ranges for prices for securities have been required, by any of said
exchanges or by such system or by order of the Commission, the National
Association of Securities Dealers, Inc. or any other governmental authority, or
(iv) if a banking moratorium has been declared by either Federal or New York
authorities.

     (b)  Liabilities.  If this Agreement is terminated pursuant to this
Section, such termination shall be without liability of any party to any other
party except as provided in

                                       17

binding upon the Underwriter, the Fund, the Adviser and their respective

controlling persons and officers, trustees and general partner referred to in
Sections 7 and 8 and their heirs and legal representatives, any legal or
equitable right, remedy or claim under or in respect of this Agreement or any

the Fund and the Adviser and their respective successors, and said controlling
persons and officers, trustees and general partner and their heirs and legal

                       FORM OF OPINION OF FUND'S COUNSEL
                          TO BE DELIVERED PURSUANT TO
                                 SECTION 5(b)

of the Commonwealth of Massachusetts.

     (ii)    The Fund has power and authority to own, lease and operate its
properties and to conduct its business as described in the Prospectus and to
enter into and perform its obligations under the Purchase Agreement.

     (iii)   The Fund is duly qualified to transact business and is in good
standing in each jurisdiction in which such qualification is required, whether
by reason of the ownership or leasing of property or the conduct of business,
except where the failure so to qualify or to be in good standing would not
result in a material adverse change in the condition, financial or otherwise, or
in the earnings, business affairs or business prospects of the Fund, whether or
not arising in the ordinary course of business (a "Material Adverse Effect").

     (iv)    The authorized, issued and outstanding capital shares of the Fund

been duly authorized for issuance and sale to the Underwriter pursuant to the

Purchase Agreement, will be validly issued and fully paid and non-assessable
(except for certain possible liability of shareholders described in the
Prospectus under "Description of Capital Shares") and no holder of the Shares is
or will be subject to personal liability by reason of being such a holder
(except for certain possible liability of shareholders described in the
Prospectus under "Description of Capital Shares").

     (vi)    The issuance of the Shares is not subject to the preemptive or
other similar rights of any securityholder of the Fund.

     (vii)   To the best of our knowledge, the Fund does not have any

of the certificate pursuant to

<PAGE>
 
Rule 497(j) or the Prospectus pursuant to Rule 497(c) or Rule 497(h), as the
case may be, has been made in the manner and within the time period required by
Rule 497(j), Rule 497(c) or Rule 497(h), as the case may be; and, to the best of
our knowledge, no stop order suspending the effectiveness of the Registration

material respects with all applicable statutory requirements and with any
applicable requirements of the declaration of trust and by-laws of the Fund. To
the best of our knowledge, there is not pending or threatened any action, suit,
proceeding, inquiry or investigation, to which the Fund is a party, or to which
the property of the Fund is subject, before or brought by any court or
governmental agency or body, domestic or foreign, which might reasonably be
expected to result in a Material Adverse Effect, or which might reasonably be
expected to materially and adversely affect the properties or assets thereof or
the consummation of the transactions contemplated in the Purchase Agreement or
the performance by the Fund of its obligations thereunder, other than those
disclosed in the Prospectus.

     (xii)   The information in the Prospectus under "Description of AMPS,"
"Description of Capital Shares," "Taxes" (other than information related to
Florida law or legal conclusions involving matters of Florida law as to which we
express no opinion) and in the Registration Statement under Item 29, to the
extent that it constitutes matters of law, summaries of legal matters, the
Fund's declaration of trust and bylaws or legal proceedings, or legal
conclusions, has been reviewed by us and is correct in all material respects.

     (xiii)  To the best of our knowledge, there are no statutes or regulations
that are required to be described in the Prospectus that are not described as
required.

     (xiv)   All descriptions in the Prospectus of contracts and other documents
to which the Fund is a party are accurate in all material respects; to the best
of our knowledge, there are no franchises, contracts, indentures, mortgages,
loan agreements, notes, leases or other instruments of the Fund required to be
described or referred to in the Registration Statement or to be filed as
exhibits thereto other than those described or referred to therein or filed or
incorporated by reference as exhibits thereto, and the descriptions thereof or
references thereto are correct in all material respects.

     (xv)    To the best of our knowledge, the Fund is not in violation of its
declaration of trust or by-laws and no default by the Fund exists in the due
performance or observance of any material obligation, agreement, covenant or
condition contained in any contract, indenture,

                                      A-2
<PAGE>
 
mortgage, loan agreement, note, lease or other agreement or instrument that is
described or referred to in the Registration Statement or the Prospectus or
filed or incorporated by reference as an exhibit to the Registration Statement.

     (xvi)   No filing with, or authorization, approval, consent, license,
order, registration, qualification or decree of, any court or governmental
authority or agency, domestic or foreign (other than under the 1933 Act, the
Investment Company Act and the Rules and Regulations, which have been obtained,
or as may be required under the securities or blue sky laws of the various
states, as to which we need express no opinion) is necessary or required in
connection with the due authorization, execution and delivery of the Purchase
Agreement, the Advisory Agreement, the Custody Agreement, the Auction Agreement
and the Letter of Representations or for the offering, issuance, sale or
delivery of the Shares.

     (xvii)  The Advisory Agreement and the Custody Agreement have each been
duly authorized and approved by the Fund and comply as to form in all material
respects with all applicable provisions of the Investment Company Act, and each
has been duly executed by the Fund.

     (xviii) Each of the Auction Agent Agreement and the Letter of
Representations has been duly authorized, executed and delivered by the Fund,
and each constitutes a valid and binding obligation of the Fund, enforceable in
accordance with its terms, subject, as to enforcement, to bankruptcy,
insolvency, reorganization or other laws relating to or affecting creditors'
rights and to general equitable principles.

     (xix)   The Fund is registered with the Commission under the Investment
Company Act as a closed-end, non-diversified management investment company, and
all required action has been taken by the Fund under the 1933 Act, the
Investment Company Act and the Rules and Regulations to make the public offering
and consummate the sale of the Shares pursuant to the Purchase Agreement; the
provisions of the declaration of trust and the by-laws of the Fund comply as to
form in all material respects with the requirements of the Investment Company
Act; and, to the best of their knowledge and information, no order of suspension
or revocation of such registration under the Investment Company Act, pursuant to
Section 8(e) of the Investment Company Act, has been issued or proceedings
therefor initiated or threatened by the Commission.

     (xx)    The execution, delivery and performance of the Purchase Agreement
and the consummation of the transactions contemplated in the Purchase Agreement
and in the Registration Statement (including the issuance and sale of the
Shares, and the use of the proceeds from the sale of the Shares as described in
the Prospectus under the caption "Use of Proceeds") and compliance by the Fund
with its obligations under the Purchase Agreement do not and will not, whether
with or without the giving of notice or lapse of time or both, conflict with or
constitute a breach of, or default or Repayment Event (as defined in Section
1(a)(xi) of the Purchase Agreement) under or result in the creation or
imposition of any lien, charge or encumbrance upon any property or assets of the
Fund pursuant to any contract, indenture, mortgage, deed of trust, loan or
credit agreement, note, lease or any other agreement or instrument, known to us,
to which the Fund is a party or by which it may be bound, or to which any of the
property or assets of the Fund is subject (except for such conflicts, breaches
or 

                                      A-3
<PAGE>
 
defaults or liens, charges or encumbrances that would not have a Material
Adverse Effect), nor will such action result in any violation of the provisions
of the declaration of trust or by-laws of the Fund, or any applicable law,
statute, rule, regulation, judgment, order, writ or decree, known to us, of any
government, government instrumentality or court, domestic or foreign, having
jurisdiction over the Fund or any of its properties, assets or operations.

     Nothing has come to our attention that would lead us to believe that the
Registration Statement or any amendment thereto, including the Rule 430A
Information and Rule 434 Information (if applicable), (except for financial
statements and schedules and other financial data included or incorporated by
reference therein or omitted therefrom, as to which we need make no statement),
at the time such Registration Statement or any such amendment became effective,
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements therein
not misleading or that the Prospectus or any amendment or supplement thereto
(except for financial statements and schedules and other financial data included
or incorporated by reference therein or omitted therefrom, as to which we need
make no statement), at the time the Prospectus was issued, at the time any such
amended or supplemented prospectus was issued or at the Closing Time, included
or includes an untrue statement of a material fact or omitted or omits to state
a material fact necessary in order to make the statements therein, in the light
of the circumstances under which they were made, not misleading.

     In rendering such opinion, such counsel may rely as to matters involving
the laws of the Commonwealth of Massachusetts upon the opinion of Bingham Dana
LLP.  Bingham Dana LLP and Brown & Wood LLP may rely, as to matter of fact (but
not as to legal conclusions), to the extent they deem proper, on certificates
and written statements of responsible officers of and accountants for the Fund
and the Adviser and public officials.  Such opinion shall not state that it is
to be governed or qualified by, or that it is otherwise subject to, any
treatise, written policy or other document relating to legal opinions,
including, without limitation, the Legal Opinion Accord of the ABA Section of
Business Law (1991).

                      INVESTMENT ADVISER TO BE DELIVERED
                           PURSUANT TO SECTION 6(c)

the laws of the State of Delaware, with power and authority to conduct its
business as described in the Registration Statement and in the Prospectus.

     (ii)  The Adviser is duly registered as an investment adviser under the
Investment Advisers Act and is not prohibited by the Investment Advisers Act or
the Investment Company Act, or the rules and regulations under such Acts, from
acting under the Advisory Agreement for the Fund as contemplated by the
Prospectus.

     (iii) This Agreement and the Advisory Agreement have been duly authorized,
executed and delivered by the Adviser, and the Advisory Agreement constitutes a
valid and binding obligation of the Adviser, enforceable in accordance with its
terms, subject, as to enforcement, to bankruptcy, insolvency, reorganization or
other laws relating to or affecting creditors' rights and to general equity
principles; and, to the best of his knowledge and information, neither the
execution and delivery of this Agreement or the Advisory Agreement nor the
performance by the Adviser of its obligations hereunder or thereunder will
conflict with, or result in a breach of, any of the terms and provisions of, or
constitute, with or without the giving of notice or the lapse of time or both, a
default under, any agreement or instrument to which the Adviser is a party or by
which the Adviser is bound, or any law, order, rule or regulation applicable to
the Adviser of any jurisdiction, court, Federal or state regulatory body,
administrative agency or other governmental body, stock exchange or securities
association having jurisdiction over the Adviser or its properties or
operations.

     (iv)  To the best of his knowledge and information, the description of the
Adviser in the Registration Statement and in the Prospectus does not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading.

                          FLORIDA COUNSEL TO THE FUND

extent that it constitutes matters of Florida law or legal conclusions involving
matters of Florida law, has been reviewed by us and is correct in all material
respects.

     (ii) Nothing has come to our attention that would lead us to believe that
the information in the Registration Statement under the caption "Investment
Objective and Policies--Special Considerations Relating to Florida Municipal
Bonds and Municipal Bonds" and in Appendix I entitled "Economic and Other
Conditions in Florida", at the time such Registration Statement or any amendment
became effective, contained an untrue statement of a material fact or omitted to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or that the information under such caption and
in such appendix in the Prospectus, at the time the Prospectus was issued, at
the time any amended or supplemented prospectus was issued or at Closing Time,
included or includes an untrue statement of a material fact or omitted or omits
to state a material fact necessary in order to make the statements therein, in
the light of the circumstances under which they were made, not
misleading.

                             FORM OF ACCOUNTANTS'
                    COMFORT LETTER PURSUANT TO SECTION 6(e)

     1.   We are independent public accountants with respect to the Company
within the meaning of the 1933 Act and the 1933 Act Regulations.

     2.  In our opinion the financial statements audited by us and included in
the Registration Statement and the Prospectus comply as to form in all material
respects with the applicable accounting requirements of the 1933 Act, the
Investment Company Act and the Rules and Regulations.

     Such accountants shall also state that they have performed specified
procedures, not constituting an audit, including a reading of the latest
available interim financial statements of the Fund, a reading of the minute
books of the Fund, made inquiries of officials of the Fund responsible for
financial accounting matters and such other inquiries and procedures as may be
specified in such letter, and on the basis of such inquiries and procedures
nothing came to their attention that caused them to believe that (A) the
unaudited financial statements do not comply as to form in all material respects
with the applicable accounting requirements of the 1933 Act, the Investment
Company Act and of the Rules and Regulations applicable to unaudited interim
financial statements included in registration statements or are not in
conformity with generally accepted accounting principles applied on a basis
substantially consistent with that of the audited financial statements included
in the Registration Statement, and (B) during the period from the date of the
unaudited financial statements included in the Registration Statement to a
specified date not more than three days prior to the date of the Purchase
Agreement, there was any change in the capital shares or net assets of the Fund
(other than by reason of the issuance of Common Shares in connection with the
Fund's dividend reinvestment plan, as specified in such letter) or any increase
in the long-term debt of the Fund, as compared with amounts shown on the
unaudited financial statements included in the Registration Statement, except
for changes which the Registration Statement discloses have occurred or may
occur; and in addition, they have performed other specified procedures, not
constituting an audit, with respect to certain amounts, percentages, numerical
data, financial information and financial statements appearing in the
Registration Statement, which previously have been specified by such accountants
and which shall be specified in such letter, and have compared certain of such
items with, and have found such items to be in agreement with, the accounting
and financial records of the Fund.

II.  THE AUCTION.
     ----------- 
     2.1.  Purpose; Incorporation by Reference of Auction
           Procedures and Settlement Procedures.
           ----------------------------------------------

           (a)  The Certificate of Designation provides that the Applicable Rate
     on shares of each series of AMPS, as the case may be, for each Dividend
     Period therefor after the Initial Dividend Period shall be the rate per
     annum that a commercial bank, trust company or other financial institution
     appointed by the Fund advises results from implementation of the Auction
     Procedures. The Board of Trustees of the Fund has adopted a resolution
     appointing IBJ Schroder Bank & Trust Company as Auction Agent for purposes
     of the Auction Procedures. The Auction Agent hereby accepts such
     appointment and agrees that, on each Auction Date, it shall follow the
     procedures set forth in this Section 2 and the Auction Procedures for the
     purpose of determining the Applicable Rate for the AMPS for the next
     Dividend Period therefor. Each periodic operation of such procedures is
     hereinafter referred to as an "Auction."

           (b)  All of the provisions contained in the Auction Procedures and in
     the Settlement Procedures are incorporated herein by reference in their
     entirety and shall be deemed to be a part hereof to the same extent as if
     such provisions were set forth fully herein.

           2.2.  Preparation for Each Auction; Maintenance
                 of Registry of Existing Holders.
                 -----------------------------------------

           (a)  Pursuant to Section 2.5 hereof, the Fund shall not designate any
     Person to act as a Broker-Dealer without the prior written approval of the
     Auction Agent (which approval shall not be withheld unreasonably). As of
     the date hereof, the Fund shall provide the Auction Agent with a list of
     the Broker-Dealers previously approved by the Auction Agent and shall cause
     to be delivered to the Auction Agent for execution by the Auction Agent a
     Broker-Dealer Agreement signed by each such Broker-Dealer. The Auction
     Agent shall keep such list current and accurate and shall indicate thereon,
     or on a separate list, the identity of each Existing Holder, if any, whose
     most recent Order was submitted by a Broker-Dealer on such list and
     resulted in such Existing Holder continuing to hold or purchasing AMPS. Not
     later than five Business Days prior to any Auction Date for which any
     change in such list of Broker-Dealers is to be effective, the Fund shall
     notify the Auction Agent in writing of such change and, if any such change
     is the addition of a Broker-Dealer to such list, the Fund shall cause to be
     delivered to the Auction Agent for execution by the Auction Agent a Broker-
     Dealer Agreement signed by such Broker-Dealer. The Auction Agent shall have
     entered into a Broker-Dealer Agreement with each Broker-Dealer prior to the
     participation of any such Broker-Dealer in any Auction.

           (b)  In the event that the Auction Date for any Auction shall be
     changed after the Auction Agent shall have given the notice referred to in
     clause (vii) of Paragraph (a) of the Settlement Procedures, the Auction
     Agent, by such means as the Auction Agent 

                                       4
<PAGE>
 
     deems practicable, shall give notice of such change to the Broker-Dealers
     not later than the earlier of 9:15 A.M. on the new Auction Date or 9:15
     A.M. on the old Auction Date.

           (c)  The provisions contained in paragraph - of the Certificate of
     Designation concerning Special Dividend Periods and the notification of a
     Special Dividend Period will be followed by the Fund and, to the extent
     applicable, the Auction Agent, and the provisions contained therein are
     incorporated herein by reference in their entirety and shall be deemed to
     be a part of this Agreement to the same extent as if such provisions were
     set forth fully herein.

           (d)  (i)  Except as otherwise provided in paragraph ____ of the
Certificate of Designation, whenever the Fund intends to include any net capital
gains or other income subject to regular Federal income tax in any dividend on
AMPS, the Fund will notify the Auction Agent of the amount to be so included at
least five Business Days prior to the Auction Date on which the Applicable Rate
for such dividend is to be established. Whenever the Auction Agent receives such
notice from the Fund, in turn it will notify each Broker-Dealer, who, on or
prior to such Auction Date, in accordance with its Broker-Dealer Agreement, will
notify its Beneficial Owners and Potential Beneficial Owners believed to be
interested in submitting an Order in the Auction to be held on such Auction
Date. Whenever the Fund includes any additional amounts in a dividend as
provided in paragraph ____ of the Certificate of Designation, the Fund will
notify the Auction Agent of such additional amounts to be so included in such
dividend at least five Business Days prior to the applicable Dividend Payment
Date. Whenever the Auction Agent receives such notice from the Fund, in turn it
will notify the Securities Depository and each Broker-Dealer, who, on or prior
to the applicable Dividend Payment Date, in accordance with its Broker-Dealer
Agreement, will notify its Beneficial Owners.

          (ii)  If the Fund makes a Retroactive Taxable Allocation, the Fund,
     within 90 days (and generally within 60 days) after the end of its fiscal
     year for which a Retroactive Taxable Allocation is made, will provide
     notice thereof to the Auction Agent and to each Holder (initially the
     Securities Depository) during such fiscal year at such Holder's address as
     the same appears or last appeared on the share books of the Fund. The Fund,
     within 30 days after such notice is given to the Auction Agent, will pay to
     the Auction Agent (who then will distribute to such Holders), out of funds
     legally available therefor, a cash amount equal to the aggregate Additional
     Dividend with respect to all Retroactive Taxable Allocations made to such
     Holders during the fiscal year in question.

           (e)  (i)  On each Auction Date, the Auction Agent shall determine the
Reference Rate and the Maximum Applicable Rate. If the Reference Rate is not
quoted on an interest basis but is quoted on a discount basis, the Auction Agent
shall convert the quoted rate to an Interest Equivalent, as set forth in
paragraph __ of the Certificate of Designation; or, if the rate obtained by the
Auction Agent is not quoted on an interest or discount basis, the Auction Agent
shall convert the quoted rate to an interest rate after consultation with the
Fund as to the method of such conversion. Not later than 9:30 A.M. on each
Auction Date, the Auction Agent shall notify the Fund and the Broker-Dealers of
the Reference Rate so determined and of the Maximum Applicable Rate.

                                       5
<PAGE>
 
           (ii) If the Reference Rate is the applicable "AA" Composite
     Commercial Paper Rate and such rate is to be based on rates supplied by
     Commercial Paper Dealers and one or more of the Commercial Paper Dealers
     shall not provide a quotation for the determination of the applicable "AA"
     Composite Commercial Paper Rate, the Auction Agent immediately shall notify
     the Fund so that the Fund can determine whether to select a Substitute
     Commercial Paper Dealer or Substitute Commercial Paper Dealers to provide
     the quotation or quotations not being supplied by any Commercial Paper
     Dealer or Commercial Paper Dealers. The Fund promptly shall advise the
     Auction Agent of any such selection. If the Fund does not select any such
     Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers,
     then the rates shall be supplied by the remaining Commercial Paper Dealer
     or Commercial Paper Dealers.

           (iii)  If, after the date of this Agreement, there is any change in
the prevailing rating of AMPS by either of the rating agencies (or substitute or
successor rating agencies) referred to in the definition of the Maximum
Applicable Rate, thereby resulting in any change in the corresponding applicable
percentage for the AMPS, as set forth in said definition (the "Percentage"), the
Fund shall notify the Auction Agent in writing of such change in the Percentage
prior to 9:00 A.M. on the Auction Date for AMPS next succeeding such change. The
Percentage for the AMPS on the date of this Agreement is as specified in
paragraph _____ of the Certificate of Designation. The Auction Agent shall be
entitled to rely on the last Percentage of which it has received notice from the
Fund (or, in the absence of such notice, the Percentage set forth in the
preceding sentence) in determining the Maximum Applicable Rate as set forth in
Section 2.2(e)(i) hereof.

           (f)  (i)  The Auction Agent shall maintain a current registry of the
Existing Holders of the shares of each series of AMPS for purposes of each
Auction. The Fund shall use its best efforts to provide or cause to be provided
to the Auction Agent within ten Business Days following the date of the Closing
a list of the initial Existing Holders of each series of AMPS, and the Broker-
Dealer of each such Existing Holder through which such Existing Holder purchased
such shares. The Auction Agent may rely upon, as evidence of the identities of
the Existing Holders, such list, the results of each Auction and notices from
any Existing Holder, the Agent Member of any Existing Holder or the Broker-
Dealer of any Existing Holder with respect to such Existing Holder's transfer of
any AMPS to another Person.

           (ii) In the event of any partial redemption of any series of AMPS,
     upon notice by the Fund to the Auction Agent of such partial redemption,
     the Auction Agent promptly shall request the Securities Depository to
     notify the Auction Agent of the identities of the Agent Members (and the
     respective numbers of shares) from the accounts of which shares have been
     called for redemption and the person or department at such Agent Member to
     contact regarding such redemption, and at least two Business Days prior to
     the Auction preceding the date of redemption with respect to shares of the
     series being partially redeemed, the Auction Agent shall request each Agent
     Member so identified to disclose to the Auction Agent (upon selection by
     such Agent Member of the Existing Holders whose shares are to be redeemed)
     the number of shares of such series of AMPS of each such Existing Holder,
     if any, to be redeemed by the Fund, provided that 

                                       6
<PAGE>
 
     the Auction Agent has been furnished with the name and telephone number of
     a person or department at such Agent Member from which it is to request
     such information. In the absence of receiving any such information with
     respect to an Existing Holder, from such Existing Holder's Agent Member or
     otherwise, the Auction Agent may continue to treat such Existing Holder as
     having ownership of the number of shares of the series of AMPS shown in the
     Auction Agent's registry of Existing Holders.

           (iii)  The Auction Agent shall register a transfer of the ownership
     of shares of a series of AMPS from an Existing Holder to another Existing
     Holder, or to another Person if permitted by the Fund, only if (A) such
     transfer is made pursuant to an Auction or (B) if such transfer is made
     other than pursuant to an Auction, the Auction Agent has been notified of
     such transfer in writing in a notice substantially in the form of Exhibit C
     to the Broker-Dealer Agreements, by such Existing Holder or by the Agent
     Member of such Existing Holder. The Auction Agent is not required to accept
     any notice of transfer delivered for an Auction unless it is received by
     the Auction Agent by 3:00 P.M. on the Business Day next preceding the
     applicable Auction Date. The Auction Agent shall rescind a transfer made on
     the registry of the Existing Holders of any AMPS if the Auction Agent has
     been notified in writing, in a notice substantially in the form of Exhibit
     D to the Broker-Dealer Agreement, by the Agent Member or the Broker-Dealer
     of any Person that (i) purchased any AMPS and the seller failed to deliver
     such shares or (ii) sold any AMPS and the purchaser failed to make payment
     to such Person upon delivery to the purchaser of such shares.

           (g)    The Auction Agent may request that the Broker-Dealers, as set
     forth in Section 3.2(c) of the Broker-Dealer Agreements, provide the
     Auction Agent with a list of their respective customers that such Broker-
     Dealers believe are Beneficial Owners of AMPS. The Auction Agent shall keep
     confidential any such information and shall not disclose any such
     information so provided to any Person other than the relevant Broker-Dealer
     and the Fund, provided that the Auction Agent reserves the right to
     disclose any such information if it is advised by its counsel that its
     failure to do so would be unlawful.

     2.3.  Auction Schedule.

IV.  THE PAYING AGENT AS TRANSFER AGENT AND REGISTRAR.
     ------------------------------------------------ 

     4.1. Original Issue of Share Certificates.
          ------------------------------------ 

     On the Date of Original Issue for any AMPS, one certificate for each series

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

     Except as provided in this Section 4.2, the shares of each series of AMPS
shall be registered solely in the name of the Securities Depository or its
nominee.  If the Securities Depository shall give notice of its intention to
resign as such, and if the Fund shall not have selected a substitute Securities
Depository acceptable to the Paying Agent prior to such resignation, then upon
such resignation, the shares of each series of AMPS, at the Fund's request, may
be registered for transfer or exchange, and new certificates thereupon shall be
issued in the name of the designated transferee or transferees, upon surrender
of the old certificate in form deemed by the Paying Agent properly endorsed for
transfer with (a) all necessary endorsers' signatures guaranteed in such manner
and form as the Paying Agent may require by a guarantor reasonably believed by
the Paying Agent to be responsible, (b) such assurances as the Paying Agent
shall deem necessary or appropriate to evidence the genuineness and
effectiveness of each necessary endorsement and (c) satisfactory evidence of
compliance with all applicable laws relating to the collection of taxes in
connection with any registration of transfer or exchange or funds necessary for
the payment of such taxes.  If the certificate or certificates for AMPS are not
held by the Securities Depository or its nominee, payments upon 

                                       11

transfer of shares in an Auction shall be made in Federal Funds or similar same-
day funds to the Auction Agent against delivery of certificates therefor.

     4.3. Removal of Legend.
          ----------------- 

     Any request for removal of a legend indicating a restriction on transfer
from a certificate evidencing AMPS shall be accompanied by an opinion of counsel
stating that such legend may be removed and such shares may be transferred free
of the restriction described in such legend, said opinion to be delivered under
cover of a letter from a Fund Officer authorizing the Paying Agent to remove the
legend on the basis of said opinion.

     4.4. Lost, Stolen or Destroyed Share Certificates.
          --------------------------------------------

certificates represented to have been lost, stolen or destroyed, upon the
fulfillment of such requirements as shall be deemed appropriate by the Fund and
by the Paying Agent, subject at all times to provisions of law, the By-Laws of
the Fund governing such matters and resolutions adopted by the Fund with respect
to lost, stolen or destroyed securities.  The Paying Agent may issue new
certificates in exchange for and upon the cancellation of mutilated
certificates.  Any request by the Fund to the Paying Agent to issue a
replacement or new certificate pursuant to this Section 4.4 shall be deemed to
be a representation and warranty by the Fund to the Paying Agent that such
issuance will comply with provisions of applicable law and the By-Laws and
resolutions of the Fund.

     4.5. Disposition of Canceled Certificates; Record Retention.
          -------------------------------------------------------

     The Paying Agent shall retain share certificates which have been canceled
in transfer or in exchange and accompanying documentation in accordance with
applicable rules and regulations of the Securities and Exchange Commission for
two calendar years from the date of such cancellation.  The Paying Agent, upon
written request by the Fund, shall afford to the Fund, its agents and counsel
access at reasonable times during normal business hours to review and make
extracts or copies (at the Fund's sole cost and expense) of such certificates
and accompanying documentation.  Upon request by the Fund at any time after the
expiration of this two-year period, the Paying Agent shall deliver to the Fund
the canceled certificates and accompanying documentation.  The Fund, at its
expense, shall retain such records for a minimum additional period of four
calendar years from the date of delivery of the records to the Fund and shall
make such records available during this period at any time, or from time to
time, for reasonable periodic, special, or other examinations by representatives
of the Securities and Exchange Commission.  The Fund also shall undertake to
furnish to the Securities and Exchange Commission, upon demand, either at their
principal office or at any regional office, complete, correct and current hard
copies of any and all such records.  Thereafter, such records shall not be
destroyed by the Fund without the approval of the Paying Agent, which approval
shall not be withheld unreasonably, but will be safely stored for possible
future reference.

     4.6. Share Register.
          -------------- 

     The Paying Agent shall maintain the share register, which shall contain a
list of the Holders, the number of shares held by each Holder and the address of
each Holder.  The Paying 

                                       12
<PAGE>
 
Agent shall record in the share register any change of address of a Holder upon
notice by such Holder. In case of any written request or demand for the
inspection of the share register or any other books of the Fund in the
possession of the Paying Agent, the Paying Agent will notify the Fund and secure
instructions as to permitting or refusing such inspection. The Paying Agent
reserves the right, however, to exhibit the share register or other records to
any person in case it is advised by its counsel that its failure to do so would
(i) be unlawful or (ii) expose it to liability, unless the Fund shall have
offered indemnification satisfactory to the Paying Agent.

     4.7. Return of Funds.
          --------------- 

     Any funds deposited with the Paying Agent by the Fund for any reason under
this Agreement, including for the payment of dividends or the redemption of

shall be repaid to the Fund upon written request by the Fund.

                                 Submitted Bids and Submitted Sell Orders are
                                 accepted and rejected in whole or in part and
                                 AMPS are allocated as provided in Paragraph
                                 10(e) of the Certificate of Designation.

                                 Auction Agent gives notice of the Auction
                                 results as set forth in Section 3.4(a) hereof.

          (b) BD agrees to maintain a list of Potential Beneficial Owners and to
contact the Potential Beneficial Owners on such list on or prior to each Auction
Date for the purposes set forth in Paragraph 10 of the Certificate of
Designation.

          (c) BD shall submit Orders to the Auction Agent in writing in
substantially the form attached hereto as Exhibit B. BD shall submit separate
Orders to the Auction Agent for each Potential Beneficial Owner or Beneficial
Owner on whose behalf BD is submitting an Order and shall not net or aggregate
the Orders of Potential Beneficial Owners or Beneficial Owners on whose behalf
BD is submitting Orders.

          (d) BD shall deliver to the Auction Agent (i) a written notice,
substantially in the form attached hereto as Exhibit C, of transfers of shares
of any series of AMPS, made through BD by an Existing Holder to another Person
other than pursuant to an Auction, and (ii) a written notice, substantially in
the form attached hereto as Exhibit D, of the failure of shares of any series of
any series of AMPS to be transferred to or by any Person that purchased or sold
shares of any series of AMPS through BD pursuant to an Auction. The Auction
Agent is not required to accept any notice delivered pursuant to the terms of
the foregoing sentence with 

                                       5
<PAGE>
 
respect to an Auction unless it is received by the Auction Agent by 3:00 P.M. on
the Business Day next preceding the applicable Auction Date.

     3.4. Notice of Auction Results.
          ------------------------- 

          (a) On each Auction Date, the Auction Agent shall notify BD by
telephone as set forth in paragraph (a) of the Settlement Procedures. On the
Business Day next succeeding such Auction Date, the Auction Agent shall notify
BD in writing of the disposition of all Orders submitted by BD in the Auction
held on such Auction Date.

          (b) BD shall notify each Beneficial Owner, Potential Beneficial Owner,
Existing Holder or Potential Holder on whose behalf BD has submitted an Order as
set forth in paragraph (b) of the Settlement Procedures, and take such other
action as is required of BD pursuant to the Settlement Procedures.

     If any Beneficial Owner or Existing Holder selling AMPS in an Auction fails
to deliver such shares, the BD of any Person that was to have purchased shares
of such series of AMPS in such Auction may deliver to such Person a number of
whole shares of such series of AMPS that is less than the number of shares that
otherwise was to be purchased by such Person.  In such event, the number of
shares of such series of AMPS to be so delivered shall be determined by such BD.
Delivery of such lesser number of shares shall constitute good delivery.  Upon
the occurrence of any such failure to deliver shares, such BD shall deliver to
the Auction Agent the notice required by Section 3.3(d)(ii) hereof.
Notwithstanding the foregoing terms of this Section 3.4(b), any delivery or non-
delivery of shares of any series of AMPS which represents any departure from the
results of an Auction, as determined by the Auction Agent, shall be of no effect
unless and until the Auction Agent shall have been notified of such delivery or
non-delivery in accordance with the terms of Section 3.3(d) hereof.  The Auction
Agent shall have no duty or liability with respect to enforcement of this
Section 3.4(b).

     3.5. Service Charge to Be Paid to BD. On the Business Day next succeeding
          -------------------------------
each Auction Date, the Auction Agent shall pay to BD from moneys received from
the Fund an amount equal to: (a) in the case of any Auction Date immediately
preceding a 7-Day Dividend Period or 28-Day Dividend Period, the product of (i)
a fraction the numerator of which is the number of days in such Dividend Period
(calculated by counting the first day of such Dividend Period but excluding the
last day thereof) and the denominator of which is 360, times (ii) 1/4 of 1%,
times (iii) $25,000, times (iv) the sum of (A) the aggregate number of AMPS
placed by BD in the applicable Auction that were (x) the subject of a Submitted
Bid of a Beneficial Owner submitted by BD and continued to be held as a result
of such submission and (y) the subject of a Submitted Bid of a Potential
Beneficial Owner submitted by BD and were purchased as a result of such
submission plus (B) the aggregate number of AMPS subject to valid Hold Orders
(determined in accordance with Paragraph 10 of the Certificate of Designation)
submitted to the Auction Agent by BD plus (C) the number of AMPS deemed to be
subject to Hold Orders by Beneficial Owners pursuant to Paragraph 10 of the
Certificate of Designation that were acquired by such Beneficial Owners through
BD; and (b) in the case of any Auction Date immediately 

                                       6
<PAGE>
 
preceding a Special Dividend Period, that amount as mutually agreed upon by the
Fund and BD, based on the selling concession that would be applicable to an
underwriting of fixed or variable rate preferred shares with a similar final
maturity or variable rate dividend period, at the commencement of such Special
Dividend Period.

     For purposes of subclause (a)(iv)(C) of the foregoing sentence, if any
Beneficial Owner who acquired shares of any series of AMPS through BD transfers
those shares to another Person other than pursuant to an Auction, then the
Broker-Dealer for the shares so transferred shall continue to be BD, provided,
however, that if the transfer was effected by, or if the transferee is, a
Broker-Dealer other than BD, then such Broker-Dealer shall be the Broker-Dealer
for such shares.

                    [Issue Description, including CUSIP number]

Ladies and Gentlemen:

     This letter sets forth our understanding with respect to certain matters
relating to the above-referenced issue (the "Securities").  Trust Company will
act as transfer agent, registrar, dividend disbursing agent, and redemption
agent with respect to the Securities.  The Securities will be issued pursuant to
a prospectus, private placement memorandum, or other such document authorizing
the issuance of a Securities dated _________, 1999 (the "Document").  Merrill
Lynch & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated ["Underwriter"]
is distributing the Securities through the Depositary Trust Company ("DTC").

     To induce DTC to accept the Securities as eligible for deposit at DTC, and
to act in accordance with respect to the Securities, Issue and Trust Company
make the following representations to DTC:

     1.  Prior to closing on the Securities on _________, 1999, there shall be
deposited with DTC one Security certificate registered in the name of DTC's
nominee, Cede & Co., which represents the total 

<PAGE>
 
number of Securities issued. Said certificate shall remain in DTC's custody as
provided in the Document. If however, the aggregate principal amount of the
Securities exceed $200 million, one certificate will be issued with respect to
each $200 million of principal amount and an additional certificate will be
issued with respect to any remaining principal amount. Each Security certificate
shall bear the following legend:

          Unless this certificate is presented by an authorized representative
     of The Depository Trust Company, a California corporation ("DTC"), to
     issuer or its agent for registration of transfer, exchange, or payment, and
     any certificate issued is registered in the name of Cede & Co., or in such
     other name as is requested by an authorized representative of DTC (and any
     payment is made to Cede & Co. or to such other entity as is requested by an
     authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE
     HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGRUL inasmuch as
     the registered owner hereof, Cede & Co., has an interest therein.

     2.   Issuer:  (a) understands that DTC  has no obligation to, and will not,
communicate to its Participants or to any person having an interest in the
Securities any information contained in the Security certificate(s); and (b)
acknowledges that neither DTC's Participants  nor any person having an interest
in the Securities shall be deemed to have notice of the provisions of the
Security certificate(s) by virtue of submission of such certificate(s) to DTC.

     3.   In the event of any solicitation of consents from or voting by holders
of the Securities, Issuer shall establish a record date for such purposes (with
no provision for revocation of consents or votes by subsequent holders) and
shall send notice of such record date to DTC not less than 15 calendar days in
advance of such record date.  Notices to DTC pursuant to this Paragraph by
telecopy shall be sent to DTC's Reorganization Department at (212) 709-6896 or
(212) 709-6897, and receipt of such notices shall be confirmed by telephoning
(212) 709-6870.  Notices to DTC pursuant to this Paragraph by mail or by any
other means shall be sent to DTC's Reorganization Department as indicated in
Paragraph 5.

     4.   In the event of a full or partial redemption of the outstanding
Securities, Issuer or Trust Company shall send a notice to DTC specifying: (a)
the number of Securities to be redeemed; and (b) the date such notice is to be
distributed to Security holders or published (the "Publication Date"). Such
notice shall be sent to DTC by a secure means (e.g., legible telecopy,
registered or certified mail, overnight delivery) in a timely manner designed to
assure that such notice is in DTC's possession no later than the close of
business on the business day before or, if possible, two business days before
the Publication Date. Issuer or Trust Company shall forward such notice either
in a separate secure transmission for each CUSIP number or in a secure
transmission for multiple CUSIP numbers (if applicable) which includes a
manifest or list of each CUSIP number submitted in that transmission. (The party
sending such notice shall have a method to verify subsequently the use of such
means and the timeliness of such notice.) The Publication date shall be not less
than 30 days nor more than 60 days prior to the redemption date. Notices to DTC
pursuant to this Paragraph by telecopy shall be sent to DTC's Call Notification
Department at (516) 227-4039 or (516) 227-4190. If the party sending the notice
does not receive a telecopy receipt from DTC confirming that the notice has been
received, such party shall telephone (516) 227-4070. Notices to DTC pursuant to
this Paragraph by mail or by any other means shall be sent to:

               Manager; Call Notification Department
               The Depository Trust Company
               711 Stewart Avenue
               Garden City, NY  11530-4719

     5.   In the event of an invitation to tender the Securities (including
mandatory tenders, exchanges, and capital changes), notice by Issuer or Trust
Company to Security holder specifying the terms of the 

                                       2
<PAGE>
 
tender and the Publication Date of such notice shall be sent to DTC by a secure
means in the manner set forth in the preceding Paragraph. Notices to DTC
pursuant to this Paragraph and notices of other corporate action by telecopy
shall be sent to DTC's Reorganization Department at (212) 709-1093 or (212) 709-
1094, and receipt of such notices shall be confirmed by telephoning (212) 709-
6884. Notices to DTC pursuant to the above by mail or by any other means shall
be sent to:

               Manager; Reorganization Department
               Reorganization Window
               The Depository Trust Company
               7 Hanover Square, 23rd Street
               New York, NY  10004-2695

     6.   All notices and payment advices sent to DTC shall contain the CUSIP
number of the Securities (listed on Schedule A hereto) and the accompanying
description of such Security, which as of the date of this letter is 
"______________________".

     7.   The Document indicates that the dividend rate for the Securities may
vary from time to time.  Absent other existing arrangements with DTC, Issuer or
Trust Company shall give DTC notice of each such change in the dividend rate, on
the same day that the new rate is determined, by telephoning the Supervisor of
DTC's Dividend Announcement Section at (212) 709-1270, or by telecopy sent to
(212) 709-1723.  Such verbal or telecopy notice shall be followed by prompt
written confirmation sent by a secure means in the manner set forth in Paragraph
4 to:

                    Manager; Announcements
                    Dividend Department
                    The Depository Trust Company
                    7 Hanover Square, 22nd Floor
                    New York, NY  10004-2695

     8.   The Document indicates that each purchaser must sign a purchaser's
letter which contains provisions restricting transfer of the Securities
purchased. Issuer and Trust Company acknowledge that as long as Cede & Co. is
the sole record owner of the Securities, Cede & Co. shall be entitled to all
voting rights applicable to the Securities and to receive the full amount of all
dividends, liquidation proceeds, and redemption proceeds payable with respect to
the Securities, even if the credits of Securities to the DTC accounts of any DTC
Participant ("Participant") result from transfers or failures to transfer in
violation of the provisions of the purchaser's letter. Issuer and Trust Company
acknowledge that DTC shall treat any Participant having Securities credited to
its DTC accounts as entitled to the full benefits of ownership of such
Securities. Without limiting the generality of the preceding sentence, Issuer
and Trust Company acknowledge that DTC shall treat any Participant having
securities credited to its DTC accounts as entitled to receive dividends,
distributions, and voting rights, if any, in respect of Securities and, subject
to Paragraphs 12 and 13, to receive certificates evidencing Securities if such
certificates are to be issued in accordance with Issuer's certificate of
incorporation. (The Treatment by DTC of the effects of the crediting by it of
Securities to the accounts of Participants described in the preceding two
sentences shall not affect the rights of Issuer, participants in auctions
relating to the Securities, purchasers, sellers, or holders of Securities
against any Participant.) DTC shall not have any responsibility to ascertain
whether any transfer of Securities is made in accordance with the provisions of
the purchaser's letter.

     9.   Issuer or Trust Company shall provide a written notice of dividend
payment and distribution information to a standard announcement service
subscribed to by DTC as soon as the information is available. In the unlikely
event that no such service exists, Issuer or Trust Company shall provide this
information directly to DTC electronically, as previously arranged by Issuer or
Trust Company and DTC,

                                       3

arranged, absent any other arrangements between Issuer or Trust Company and DTC,
such information should be sent by telecopy to DTC's Dividend Department at

by telephoning (212) 709-1270. Notices to DTC pursuant to the above by mail or
by any other means shall be addressed as follows:

                    Redemption Deposit Account #066-027608

distributions, or redemption proceeds may be sent.

                                       4

     15.  In the event of a redemption acceleration, or any similar transaction
(e.g., tender made and accepted in response to Issuer's or Trust Company's
invitation) necessitating a reduction in the number of Securities outstanding,
or an advance refunding of part of the Securities outstanding DTC, in its
discretion: (a) may request Issuer or Trust Company to issue and authenticate a
new Security certificate; or (b) may make an appropriate notation on the
Security certificate indicating the date and amount of such reduction in the
number of Securities outstanding, except in the case of final redemption, in
which case the certificate the certificate will be presented to Issuer or Trust
Company prior to payment, if required.

     16.  In the event that Issuer determines that beneficial owners of
Securities shall be able to obtain certificated Securities, Issuer or Trust
company shall notify DTC of the availability of certificates.  In such event,
Issuer or Trust Company shall issue, transfer, and exchange certificates in
appropriate amounts, as required by DTC and others.

     17.  DTC may discontinue providing its services as securities depository
with respect to the Securities at any time by giving reasonable notice to Issuer
or Trust Company (at which time DTC will confirm with Issuer or Trust Company
the aggregate principal amount of Securities outstanding).  Under such
circumstances, at DTC's request Issuer and Trust Company shall cooperate fully
with DTC by taking appropriate action to make available one or more separate
certificates evidencing Securities to any DTC Participant having Securities
credited to its DTC accounts.

     18.  Issuer hereby authorized DTC to provide to Trust Company security
position listings of Participants with respect to the Securities from time to
time at the request of Trust Company.  Issuer also authorizes DTC, in the event
of a partial redemption of Securities, to provide Trust Company, upon request,
with the names of those Participants whose positions in Securities have been
selected for redemption by DTC.  DTC will use its best efforts to notify Trust
Company of those Participants whose positions in Securities have been selected
for redemption by DTC.  Issuer authorizes and instructs Trust Company to provide
DTC with such signatures, examples of signatures, and authorizations to act as
may be deemed necessary or appropriate by DTC to permit DTC to discharge its
obligations to its Participants and appropriate regulatory authorities.  Such
requests for security position listings shall be sent to DTC's Reorganization
Department in the manner set forth in Paragraph 5.

     This authorization, unless revoked by Issuer, shall continue with respect
to the Securities while any Securities are on deposit at DTC, until and unless
Trust Company shall no longer be acting.  In such event, Issuer shall provide
DTC with similar evidence, satisfactory to DTC, of the authorization of any
successor thereto so to act.

     19.  Nothing herein shall be deemed to require Trust Company to advance
funds on behalf of Issuer.

     20.  This Letter of Representations may be executed in any number of
counterparts, each of which when so executed shall be deemed to be an original,
but all such counterparts together constitute but one and the same instrument.

     21.  This Letter of Representations is governed by, and shall be construed
in accordance with, the laws of the State of California.

                     MUNIHOLDINGS FLORIDA INSURED FUND IV

                      IBJ WHITEHALL BANK & TRUST COMPANY
                             Dated          , 1999

     1.  This Rider supersedes any contradictory language set forth in the
     Letter of Representations to which it is appended.  Capitalized terms used
     and not defined herein have the meaning set forth in the Letter of
     Representations to which this Rider is appended.

     2.  The Prospectus indicates that in the event the Issuer retroactively
     allocates any net capital gains or other income subject to regular Federal
     income tax to AMPS without having given advance notice thereof to the
     Auction Agent as described in the Prospectus solely by reason of the fact
     that such allocation is made as a result of the redemption of all or a
     portion of the AMPS outstanding or the liquidation of the Issuer (the
     amount of such allocation being referred to herein as a "Retroactive
     Taxable Allocation"), the Issuer, within 90 days (and generally within 60
     days) after the end of the Issuer's fiscal year for which a Retroactive
     Taxable Allocation is made, will provide notice thereof to the Auction
     Agent and to each holder of AMPS (initially Cede & Co. as nominee of DTC)
     during such fiscal year at such holder's address as the same appears or
     last appeared on the stock books of the Issuer.  The Issuer, within 30 days
     after such notice is given to the Auction Agent, will pay to the Auction
     Agent (who then will distribute to such holders of AMPS), out of funds
     legally available therefor, an amount equal to the aggregate Additional
     Dividend with respect to all Retroactive Taxable Allocations made to such
     holders during the fiscal year in question.

     3.  The Issuer will notify DTC, at least 10 Business Days prior to the
     payment date for any Additional Dividends, of (i) the record date for
     holders of AMPS entitled to receive Additional Dividends, (ii) the amount
     of Additional Dividends payable on a per share basis to such holders and
     (iii) the CUSIP numbers set forth on the stock certificates representing
     such AMPS.

     4.  The Prospectus indicates that if the Issuer does not give advance
     notice of the amount of net capital gains or other income subject to
     regular Federal income tax to be included in a dividend on AMPS in the
     related Auction, the Issuer may include such taxable income in a dividend
     on AMPS if it increases the dividend by an additional amount calculated as
     if such income were a Retroactive Taxable Allocation and the additional
     amount were an Additional Dividend.  The Issuer or the Auction Agent will
     notify DTC, at least five Business Days prior to the applicable Dividend
     Payment Date, of the amount of such additional amount to be included in the
     dividend on a per share basis.
