                SUBJECT TO COMPLETION, DATED SEPTEMBER 20, 1999


PROSPECTUS

                                  $70,000,000

                    KEMPER STRATEGIC MUNICIPAL INCOME TRUST
   MUNICIPAL AUCTION RATE CUMULATIVE PREFERRED ("MUNICIPAL PREFERRED") SHARES
                             2,800 SHARES, SERIES T
                    LIQUIDATION PREFERENCE $25,000 PER SHARE


     Kemper Strategic Municipal Income Trust (the "Fund") is selling 2,800
Series T Municipal Auction Rate Cumulative Preferred Shares. The Fund is a
closed-end, non-diversified management investment company. The Fund's investment
adviser is Scudder Kemper Investments, Inc. ("Scudder Kemper" or the "Adviser").
The Fund's investment objective is to provide a high level of current income
exempt from federal income tax. The Fund seeks to achieve this objective by
investing in a portfolio of tax-exempt municipal securities. The Fund invests at
least 50% of its total assets in investment grade municipal securities or
unrated municipal securities of comparable quality and may invest up to 50% of
its total assets in high-yield municipal securities that are rated below
investment grade and involve certain risks. Securities rated below investment
grade are commonly known as "junk bonds." The Fund generally emphasizes
investments in municipal securities with longer term maturities, but the degree
of such emphasis depends upon market conditions, as perceived by Scudder Kemper,
at the time of investment, including the relative yields available on securities
of different maturities and expectations of future changes in interest rates.
There is no assurance that the Fund will achieve its investment objective. An
investment in the Fund is not appropriate for all investors.


     Investors in Municipal Preferred shares will be entitled to receive cash
dividends at an annual rate that may vary for the successive dividend periods
for such shares. The dividend rate on the Municipal Preferred shares for the
initial period from and including the date of issue to but excluding
  , 1999 will be      % per year. For each subsequent period, the auction agent
will determine the dividend rate for a particular period by an auction conducted
on the business day prior to that period. Investors in shares of Municipal
Preferred may participate in auctions through their broker-dealers in accordance
with the procedures specified herein. The Fund may redeem shares of Municipal
Preferred as described under "Description of Municipal Preferred -- Redemption."


     This Prospectus sets forth concisely the information you should know before
investing, including information about risks. You should read this Prospectus
before you invest and keep it for future reference. The Fund's Statement of
Additional Information ("SAI"), dated September ____, 1999, contains additional
information about the Fund and is incorporated by reference into (which means it
is considered to be a part of) this Prospectus. You may obtain a free copy of
the SAI by calling 1-800-621-1048 or by writing to the Fund at 222 South
Riverside Plaza, Chicago, Illinois 60606. A table of contents to the SAI is

Fund-related materials at the Securities and Exchange Commission's internet web
site (http://www.sec.gov).

THE OFFERING..................   The Fund is offering a total of 2,800 shares of
                                 Series T Municipal Preferred at a purchase
                                 price of $25,000 per share plus dividends, if
                                 any, that have accumulated from the date the
                                 Fund first issues the shares. Salomon Smith
                                 Barney Inc. is offering the shares as
                                 underwriter.

                                 The Municipal Preferred shares will be
                                 preferred shares of the Fund that entitle their
                                 holders to receive cash dividends at an annual
                                 rate that may vary for the successive dividend
                                 periods for such shares. In general, except as
                                 described under "-- Dividends and Dividend
                                 Periods" and "Description of Municipal

                                 each dividend period will be seven days. The
                                 auction agent will determine the dividend rate
                                 for a particular period by an auction conducted
                                 on the business day immediately prior to the
                                 start of that dividend period.

                                 Investors and potential investors in the
                                 Municipal Preferred shares may participate in
                                 auctions for the Municipal Preferred shares
                                 through their broker-dealers.

                                 Generally, investors in Municipal Preferred
                                 shares will not receive certificates
                                 representing ownership of their shares. The
                                 securities depository (The Depository Trust
                                 Company or any successor) or its nominee for
                                 the account of the investor's agent member
                                 (generally the investor's broker-dealer) will
                                 maintain record ownership of the Municipal
                                 Preferred shares in book-entry form. An
                                 investor's agent member, in turn, will maintain
                                 records of that investor's beneficial ownership
                                 of Municipal Preferred shares.

INVESTMENT OBJECTIVE AND
POLICIES......................   The Fund's investment objective is to provide a
                                 high level of current income exempt from
                                 federal income tax. An investment in Municipal
                                 Preferred shares may not be appropriate for
                                 certain investors (e.g., most retirement plans)
                                 and there is no assurance that the Fund will
                                 achieve its investment objective.


                                 The Fund seeks to achieve its objective by
                                 investing in a portfolio of tax-exempt
                                 municipal securities. During normal market
                                 conditions, at least 80% of the Fund's net
                                 assets will be invested in municipal
                                 securities. The Fund invests at least 50% of
                                 its total assets in municipal securities rated
                                 at the time of purchase within the four highest
                                 grades by Standard & Poor's Ratings Services
                                 ("S&P") or Moody's Investors Service, Inc.
                                 ("Moody's") and unrated municipal securities
                                 which, in the opinion of Scudder Kemper, have
                                 equivalent credit characteristics and are of
                                 comparable quality. The Fund may invest up to
                                 50% of its total assets in high-yield municipal
                                 securities rated BB or lower by S&P or Ba or
                                 lower by Moody's or unrated municipal
                                 securities which, in the opinion of Scudder
                                 Kemper, have equivalent credit characteristics
                                 and are of comparable quality. Securities rated
                                 BB or lower by S&P and Ba or lower by Moody's
                                 are below investment grade and are regarded by
                                 S&P and Moody's, on balance, as predominantly
                                 speculative with respect to the issuer's
                                 capacity to pay interest and repay principal in
                                 accordance with the terms of the obligation.
                                 The Fund will not purchase municipal securities
                                 rated lower than B- by S&P or B by Moody's or
                                 unrated municipal securities that Scudder
                                 Kemper considers comparable. The Fund generally
                                 emphasizes investments in municipal securities
                                 with longer term maturities, but the degree of
                                 such emphasis depends upon market conditions,
                                 as perceived by Scudder Kemper, at the time of
                                 investment, including the relative yields
                                 available on securities of different maturities
                                 and expectations of future changes in interest
                                 rates. The Fund may also employ certain trading
                                 strategies such as purchasing and selling
                                 securities on a "when issued" or "forward
                                 delivery" basis and engaging in certain hedging
                                 techniques, including financial futures and
                                 options transactions.



PRINCIPAL INVESTMENT RISKS....   Investment in municipal securities of below
                                 investment grade quality involves special risks
                                 as compared with investment in higher grade
                                 municipal securities. These risks include
                                 greater sensitivity to general market price
                                 volatility and less secondary market trading.
                                 Securities rated below investment grade are
                                 commonly known as "junk bonds." Such securities
                                 are regarded, on balance, as predominantly
                                 speculative with respect to the issuer's
                                 ability to pay interest and repay principal
                                 owed. If interest rates fall, the Fund may have
                                 less income available to make interest payments
                                 on the Municipal Preferred. In addition, in
                                 such an interest rate environment, issuers of
                                 callable bonds may "call" or prepay the bonds,
                                 possibly requiring the Fund to reinvest the
                                 proceeds in a lower yielding security.
                                 Securities that have longer maturities tend to
                                 fluctuate more in price in response to changes
                                 in market interest rates than do securities
                                 with shorter maturities. The Fund and its
                                 returns are further subject


                                        2

                                 to inflation risk, risks arising due to the
                                 Fund's non-diversified status and portfolio
                                 composition, which includes securities that are
                                 not widely held. The Fund is also subject to
                                 ratings and asset coverage risk, which could
                                 require the Fund to alter its portfolio or
                                 redeem Municipal Preferred shares. Shares of
                                 Municipal Preferred may not be transferable at
                                 an auction if the auction fails and may not be
                                 able to be sold in the secondary market. The
                                 Fund could be adversely affected if computer
                                 systems on which the Fund relies are unable to
                                 correctly process date-related information on
                                 and after January 1, 2000.


INVESTMENT ADVISER............   The Fund's investment adviser is Scudder Kemper
                                 Investments, Inc. The Adviser, including
                                 certain of its predecessors, has been engaged
                                 in the management of investment companies for
                                 more than 50 years and is among the nation's
                                 largest asset management companies. As of June
                                 30, 1999, total assets under management by the
                                 Adviser were more than $290 billion for
                                 investment company, corporate, pension,
                                 profit-sharing and other accounts. The Adviser
                                 receives an annualized fee, calculated and paid
                                 monthly, in the amount of 0.60% of the Fund's
                                 average weekly net assets. The Adviser will
                                 benefit from an increase in the Fund's assets
                                 resulting from the offering.

DIVIDENDS AND DIVIDEND
PERIODS.......................   Dividends on Municipal Preferred shares are
                                 cumulative from the date the shares are first
                                 issued. The Fund will pay dividends on the
                                 shares of Municipal Preferred, out of legally
                                 available funds and when declared by the Board
                                 of Trustees, beginning on             , 1999.

                                 After the initial dividend period, each
                                 dividend period for the shares of Municipal
                                 Preferred will generally consist of seven days;
                                 provided, however, that before any auction, the
                                 Fund may decide, subject to limitations and
                                 only if it gives the required notices, to
                                 declare a special dividend period of up to five
                                 years. Accordingly, in the case of dividend
                                 periods that are not special dividend periods,
                                 dividends generally will be payable on each
                                 succeeding Wednesday. The Fund may specify
                                 different dividend payment dates for special
                                 dividend periods.

                                 The Fund will pay dividends through the
                                 securities depository (The Depository Trust
                                 Company) on each dividend payment date.

                                 The dividend rate on the shares of Municipal
                                 Preferred for the period from and including the
                                 date of issue to but excluding             ,
                                 1999 will be      % per year. For each
                                 subsequent dividend period, the auction agent
                                 (Bankers Trust Company) will determine the
                                 dividend rate on Municipal Preferred shares
                                 through an auction.

MAXIMUM DIVIDEND RATE.........   Generally, the rate at which the Fund pays
                                 dividends on shares of Municipal Preferred may
                                 not exceed the maximum dividend rate. The
                                 maximum dividend rate may vary for different
                                 dividend periods. The maximum dividend rate is
                                 based upon the current credit rating assigned
                                 to the shares of Municipal Preferred and an
                                 independent reference rate that may vary over
                                 time.

                                        3
<PAGE>   8


                                 If the number of shares of Municipal Preferred
                                 available during an auction exceeds the total
                                 number of shares subject to bids for that
                                 auction at less than or equal to the maximum
                                 dividend rate, then the dividend rate for a
                                 subsequent dividend period will be the maximum
                                 dividend rate.



                                 In addition, if the Fund fails to pay a
                                 dividend on shares of Municipal Preferred, or
                                 if the Fund fails to pay the full redemption
                                 price for shares of Municipal Preferred when
                                 due, then the dividend rate for the subsequent
                                 dividend period will be, in this instance, the
                                 maximum dividend rate. If, however, the Fund
                                 cures its failure to pay a dividend or to pay
                                 the full redemption price, then the maximum
                                 dividend rate will not automatically apply.


ASSET MAINTENANCE.............   Under the Fund's Certificate of Designation for
                                 Preferred Shares (the "Certificate"), which
                                 establishes and fixes the rights and
                                 preferences of the shares of Municipal
                                 Preferred, the Fund must maintain

                                      - asset coverage of the Municipal
                                        Preferred shares as required by the
                                        rating agency or agencies rating the
                                        Municipal Preferred shares, and

                                      - asset coverage of the Municipal
                                        Preferred shares of at least 200% as
                                        required by the 1940 Act.


                                 Based on the composition of the Fund's
                                 portfolio and market conditions as of August
                                 31, 1999, the asset coverage of the Municipal
                                 Preferred shares as measured pursuant to the
                                 1940 Act would be approximately 277% if the
                                 Fund were to issue all Municipal Preferred
                                 shares offered in this Prospectus, representing
                                 approximately 36% of the Fund's capital.


MANDATORY REDEMPTION..........   If the Fund does not maintain its required
                                 asset coverage, it must redeem shares of
                                 Municipal Preferred at $25,000 per share plus
                                 any dividends that accumulate and remain unpaid
                                 up to the date fixed for redemption. The Fund
                                 will limit redemption to the number of
                                 Municipal Preferred shares, together with all
                                 other preferred shares of the Fund, if any,
                                 necessary to restore the required asset
                                 coverage. As of the date of this offering,
                                 there are no other preferred shares
                                 outstanding. The Fund may avoid mandatory
                                 redemption by restoring its required asset
                                 coverage pursuant to rating agency guidelines.
                                 The provisions of the 1940 Act may restrict the
                                 Fund's ability to make a mandatory redemption
                                 in connection with a failure to comply with the
                                 rating agencies' asset coverage requirements.

OPTIONAL REDEMPTION...........   The Fund, at its option and subject to various
                                 conditions, may choose to redeem all or a
                                 portion of the shares of Municipal Preferred
                                 generally on the second business day preceding
                                 any dividend payment date at the price of
                                 $25,000 per share plus accumulated but unpaid
                                 dividends, if any, whether or not earned or
                                 declared to (but not including) the date fixed
                                 for redemption, and, during some special rate
                                 periods, any applicable premium.

LIQUIDATION PREFERENCE........   The liquidation preference (that is, the amount
                                 the Fund must pay to Municipal Preferred
                                 shareholders if the Fund is liqui-

                                 be $25,000 per share plus accumulated but
                                 unpaid dividends, if any, whether or not earned
                                 or declared.

VOTING RIGHTS.................   The 1940 Act requires that the holders of
                                 Municipal Preferred shares, and the holders of
                                 any other preferred shares of the Fund, voting
                                 as a separate class, have the right to

                                      - elect at least two trustees at all
                                        times, and

                                      - elect a majority of the trustees at any
                                        time when dividends on the Municipal
                                        Preferred shares, or any other preferred
                                        shares of the Fund, are unpaid for two
                                        full years.


                                 In each case, the holders of common shares,
                                 Municipal Preferred shares, and any other
                                 preferred shares of the Fund, voting together
                                 as a single class, will elect the remaining
                                 trustees. The holders of Municipal Preferred
                                 shares, and the holders of any other preferred
                                 shares of the Fund, will vote as a separate
                                 class or classes on other matters as required
                                 under the Fund's Amended and Restated Agreement
                                 and Declaration of Trust (the "Declaration of
                                 Trust"), the 1940 Act and Massachusetts law.
                                 Each common share, each Municipal Preferred
                                 share, and each share of any other class of
                                 preferred shares of the Fund is entitled to one
                                 vote per share.


TAXATION......................   Dividends on shares of Municipal Preferred will
                                 be exempt from regular federal income tax in
                                 the hands of owners of such shares to the
                                 extent such dividends are payable from
                                 tax-exempt income earned on the Fund's
                                 investments. All or a portion of the Fund's
                                 dividends may be subject to the federal
                                 alternative minimum tax. The Fund is currently
                                 required to allocate net capital gain and other
                                 income taxable for federal income tax purposes,
                                 if any, proportionately between common shares
                                 of beneficial interest and shares of Municipal
                                 Preferred. The Fund shall, in the case of a
                                 seven-day dividend period or a special dividend
                                 period of 28 days or fewer for the shares of
                                 Municipal Preferred, and may, in the case of
                                 any other special dividend period for such
                                 shares, give notice of the amount of any income
                                 taxable for federal income tax purposes to be
                                 included in a dividend on shares of Municipal
                                 Preferred in advance of the related auction.
                                 The amount of taxable income allocable to
                                 shares of Municipal Preferred will depend upon
                                 the amount of such income realized by the Fund,
                                 but is not generally expected to be
                                 significant.

SECONDARY MARKET TRADING......   Broker-dealers may, but are not obligated to,
                                 maintain a secondary market in shares of
                                 Municipal Preferred outside of auctions. There
                                 can be no assurance that a secondary market
                                 will develop or, if it does develop, that it
                                 will provide owners with liquidity of
                                 investment. Shares of Municipal Preferred may
                                 be transferred outside of auctions only to a
                                 broker-dealer or such other persons who may be
                                 permitted by the Fund.


RATINGS.......................   The Fund will not issue shares of Municipal
                                 Preferred unless such shares have a rating of
                                 aaa from Moody's and AAA from S&P.

      asset value during the year. Total return based on market value reflects
      changes in market value. Each figure includes reinvestment of dividends.
      These figures will differ depending upon the level of any discount from or
      premium to net asset value at which the Fund's shares trade during the

                                    THE FUND

     Kemper Strategic Municipal Income Trust is a closed-end, non-diversified
management investment company. The Fund was organized as a Massachusetts
business trust on August 3, 1988, and is registered under the 1940 Act. The Fund
commenced investment operations on March 22, 1989 upon the closing of an initial
public offering of its common shares. As of August 31, 1999, the Fund had net
assets of approximately $125 million. On August 31, 1999, the Fund had
outstanding approximately 10,742,480 common shares. The Fund's principal office
is located at 222 South Riverside Plaza, Chicago, Illinois 60606, and its
telephone number is 1-800-621-1048.

                                USE OF PROCEEDS


     The net proceeds of this offering will be approximately $          , after
the payment of the underwriting commission to Salomon Smith Barney Inc. (the
"underwriter") and estimated offering costs. The net proceeds of the offering
will be invested in accordance with the Fund's investment objective and
policies. It is presently anticipated that this may take up to three months from
the offer and sale of the Municipal Preferred shares, depending on market
conditions and the availability of appropriate securities. Pending such
investment, it is anticipated that the proceeds will be invested in short-term
tax-exempt securities.

+ The ratings of S&P and Moody's represent their opinions as to the quality of
  securities that they undertake to rate. The percentage shown reflects the
  higher of Moody's or S&P's ratings. Ratings are relative and subjective and
  not absolute standards of quality. S&P's rating categories may be modified
  further by a plus (+) or minus (-) in AA, A, BBB, BB, B and C ratings. Moody's
  ratings categories may be modified further by a 1, 2 or 3 in Aa, A, Baa, Ba

* Securities that are not rated by S&P or Moody's may be rated by nationally
  recognized statistical rating organizations other than S&P or Moody's, or may
  not be rated by any such organization. With respect to the percentage of the
  Fund's assets invested in such securities, the Adviser believes that these are
  of comparable quality to rated municipal securities. This determination is
  based on the Adviser's own internal evaluation and does not necessarily
  reflect how such securities would be rated by S&P or Moody's if either were to
  rate the securities. The Adviser's determination of the equivalent quality of

                    INVESTMENT OBJECTIVE, POLICIES AND RISKS

INVESTMENT OBJECTIVE

     The Fund's investment objective is to provide a high level of current
income exempt from federal income tax. The Fund seeks to achieve this objective
by investing in a portfolio of tax-exempt municipal securities. The Fund would
not ordinarily be a suitable investment for tax-exempt retirement plans or other
investors unable to benefit from tax-exempt income. The Fund has not established
any limit on the percentage of its portfolio that may be invested in municipal
securities subject to the alternative minimum tax provisions of federal tax law,
and a substantial portion of the income produced by the Fund may be taxable
under the alternative minimum tax. The Fund therefore would not ordinarily be a
suitable investment for investors who are subject to the alternative minimum
tax. The suitability of the Fund for these investors will depend upon a
comparison of the yield likely to be provided from the Fund with the yield from
comparable tax-exempt investments not subject to the alternative minimum tax and
with the yield from comparable fully taxable investments in light of each such
investor's tax position. See "Taxes."

INVESTMENT POLICIES


     General Composition of the Fund.  During normal market conditions, at least
80% of the Fund's net assets will be invested in municipal securities. The Fund
invests at least 50% of its total assets in tax-exempt municipal securities
rated at the time of purchase within the four highest grades (Baa or BBB or
better) by Moody's or S&P, which are considered "investment grade" securities,
and unrated municipal securities which, in the opinion of Scudder Kemper, have
equivalent credit characteristics and are of comparable quality. Municipal
securities rated Baa by Moody's are considered medium grade obligations which
lack outstanding investment characteristics and in fact have speculative
characteristics as well, while municipal securities rated BBB by S&P are
regarded as having an adequate capacity to pay principal and interest, although
adverse economic conditions or changing circumstances may lead to a weakened
capacity of the issuer to meet its financial commitment to the obligation. The
Fund may invest up to 50% of its total assets in high-yield municipal securities
rated BB or lower by S&P or Ba or lower by Moody's or unrated municipal
securities which, in the opinion of Scudder Kemper, have equivalent credit
characteristics and are of comparable quality. Securities rated BB or lower by
S&P or Ba or lower by Moody's are below investment grade and are regarded by S&P
and Moody's, on balance, as predominantly speculative with respect to capacity
to pay interest and repay principal in accordance with the terms of the
obligation. Securities rated below investment grade are commonly known as "junk
bonds." The lowest quality municipal securities in which the Fund may invest are
those rated B- by S&P or B by Moody's or unrated municipal securities which, in
the opinion of Scudder Kemper, have credit characteristics equivalent to, and
will be of comparable quality to, such B- or B rated municipal securities. A
general description of Moody's and S&P's ratings of municipal securities is set
forth in Appendix A to the SAI. The ratio of investment grade municipal
securities to higher yielding, lower quality municipal securities in the Fund's
portfolio will be adjusted by Scudder Kemper for both income potential and risk
in order to seek to achieve the Fund's investment objective. An investment in
the Fund may not be appropriate for all investors and there is no assurance that
the Fund will achieve its investment objective. The Fund generally emphasizes
investments in municipal securities with longer term maturities (i.e., 10 or
more years to maturity at the time of purchase), but the degree of such emphasis
depends upon market conditions, as perceived by Scudder Kemper, at the time of
investment, including the relative yields available on securities of different
maturities and expectations of future changes in interest rates. The Fund will
also engage in hedging practices to the extent deemed appropriate by Scudder
Kemper. The Fund may also invest in zero-coupon bonds and inverse floaters. See
"-- Additional Investment Practices."


     The foregoing policies as to ratings of portfolio investments apply only at
the time of the purchase of a security, and the Fund is not required to dispose
of a security in the event Moody's or S&P subsequently downgrades its assessment
of the credit characteristics of a particular issuer.

     During temporary defensive periods (e.g., times when, in the opinion of
Scudder Kemper, temporary imbalances of supply and demand or other temporary
dislocations in the tax-exempt bond market adversely
                                        9
<PAGE>   14

affect the price at which municipal securities are available), the Fund may
invest any percentage of its net assets in taxable temporary investments. The
Fund will invest only in temporary investments which are U.S. Government
securities and other securities rated within the two highest grades by Moody's
or S&P, and which mature within one year from the date of purchase. Temporary
investments of the Fund may also include repurchase agreements. See
"-- Additional Investment Practices." To the extent the Fund invests during
temporary defensive periods in taxable investments, the Fund will not at such
times be in a position to achieve its investment objective of tax-exempt income.

     The Fund's objective, and certain fundamental investment restrictions set
forth in the SAI, may not be changed without a vote of holders of common shares
and Municipal Preferred shares voting together as a single class and the holders
of Municipal Preferred shares voting as a separate class. See "Description of
Municipal Preferred -- Voting Rights." Except for its investment objective and
fundamental investment restrictions, the policies of the Fund may be changed by
the Board of Trustees without action by holders of common shares and Municipal
Preferred shares.

     Municipal Securities.  Municipal securities include debt obligations issued
by states, cities, local authorities, and possessions and certain territories of
the United States to obtain funds for various public purposes, including the
construction of such public facilities as airports, bridges, highways, housing,
hospitals, mass transportation, schools, streets and water and sewer works.
Other public purposes for which municipal securities may be issued include the
refinancing of outstanding obligations, the obtaining of funds for general
operating expenses and for loans to other public institutions and facilities. In
addition, certain industrial development, private activity and pollution control
bonds may be included within the term municipal securities if the interest paid
thereon qualifies as exempt from federal income tax. Municipal securities in
which the Fund invests, except for temporary investments, bear interest that, in
the opinion of bond counsel to the issuer of a given municipal security, is
exempt from federal income tax, although such interest may be subject to the
alternative minimum tax. The Fund will not typically make an independent
determination as to whether a bond produces income exempt from federal income
tax.

     The two principal classifications of municipal securities are "general
obligation" and "revenue" bonds. General obligation bonds are secured by the
issuer's pledge of its full faith, credit and taxing power for the payment of
principal and interest. Revenue bonds are payable only from the revenues derived
from a particular facility or class of facilities or, in some cases, from the
proceeds of a special excise or other specific revenue source. Industrial
development, private activity and pollution control bonds 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. There are, of course, variations in the level
of security of municipal securities, both within a particular classification and
between classifications, depending on numerous factors.

     Also included within the general category of municipal securities are
participations in lease obligations or installment purchase contract obligations
(hereinafter collectively called "lease obligations") of municipal authorities
or entities. Although lease obligations do not constitute general obligations of
the municipality for which the municipality's taxing power is pledged, a lease
obligation is ordinarily backed by the municipality'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 municipality has no obligation to make lease or installment purchase
payments in future years unless money is appropriated for such purpose on a
yearly basis. In addition to the "non-appropriation" risk, these securities
represent a relatively new type of financing that has not yet developed the
depth of marketability associated with more conventional bonds. Although
"non-appropriation" lease obligations are secured by the leased property,
disposition of the property in the event of foreclosure might prove difficult.
The Fund seeks to minimize these risks by not investing more than 10% of its
total assets in lease obligations that contain "non-appropriation" clauses, and
by only investing in those "non-appropriation" lease obligations where (1) the
nature of the leased equipment or property is such that its ownership or use is
essential to a governmental function of the municipality, (2) the lease payments
will commence amortization of principal at an early date resulting in an average
life of seven years or less for the lease obligation, (3) appropriate covenants
will be obtained from the municipal obligor prohibiting the substitution or
purchase of similar equipment if lease payments are not appropriated, (4) the
investment is of a size that
                                       10
<PAGE>   15

will be attractive to institutional investors, and (5) the underlying leased
equipment has elements of portability and/or use that enhance its marketability
in the event foreclosure on the underlying equipment was ever required.

     Certain municipal securities may carry variable or floating rates of
interest whereby the rate of interest is not fixed but varies with changes in
specified market rates or indexes, such as a bank prime or a tax-exempt money
market index. As used in this Prospectus, the term municipal securities also
includes tax-exempt notes, municipal commercial paper and municipal lease
obligations having shorter term maturities, although, as noted above, the Fund
intends to emphasize investments in municipal securities with longer term
maturities.

     The yields on municipal securities are dependent on a variety of factors,
including the condition of the general money market and the municipal securities
market, the size of a particular offering, the maturity of the obligation and
the rating of the issue. The ratings of Moody's and S&P represent their opinions
as to the quality of those municipal securities that they rate. It should be
emphasized, however, that ratings are general and are not absolute standards of
quality. Consequently, municipal securities with the same maturity, coupon and
rating may have different yields while obligations of the same maturity and
coupon with different ratings may have the same yield. The market value of
outstanding municipal securities will vary with changes in prevailing interest
rate levels and as a result of changing evaluations of the ability of their
issuers to meet interest and principal payments.

     Obligations of issuers of municipal securities are subject to the
provisions of bankruptcy, insolvency and other laws affecting the rights and
remedies of creditors, such as the U.S. Bankruptcy Code. In addition, the
obligations of such issuers may become subject to the laws enacted in the future
by Congress, state legislatures or referenda extending the time for payment of
principal and/or interest, or imposing other constraints upon enforcement of
such obligations or upon municipalities to levy taxes. There is also the
possibility that, as a result of legislation or other conditions, the power or
ability of any issuer to pay, when due, the principal of and interest on its
municipal securities may be materially affected.

     High Yield Municipal Securities.  Investors should carefully consider their
ability to assume the risks of owning shares of an investment company which
invests in lower-rated securities before making an investment in the Fund. The
lower rating of certain securities held by the Fund reflects a greater
possibility that the financial condition of the issuer, or adverse changes in
general economic conditions, or both, may impair the ability of the issuer to
make payments of income and principal. In addition, these medium and lower rated
or unrated municipal securities are frequently traded only in markets where the
number of potential purchasers and sellers, if any, is very limited. This
consideration may have the effect of limiting the Fund's ability to purchase
such securities and may also have the effect of limiting the ability of the Fund
to sell such securities at their fair value in order to respond to changes in
the economy or the financial markets.

     Like those of other fixed-income securities, the values of such lower-rated
securities fluctuate in response to changes in interest rates. In addition, the
values of certain of such securities are also affected by general economic
conditions and business conditions affecting the specific industries of the
issuers. Changes by recognized rating services in their ratings of any
fixed-income securities and in the ability of an issuer to make payments of
interest and principal may also affect the value of these investments. Changes
in the value of portfolio securities generally will not affect cash income
derived from such securities, but will affect the Fund's net asset value.

     Scudder Kemper seeks to minimize the risks involved in investing in
lower-rated municipal securities through careful investment analysis. It should
be noted, however, that the amount of information about the financial condition
of an issuer of municipal securities may not be as extensive as that which is
made available by corporations whose securities are publicly traded. Because the
Fund may invest up to 50% of its total assets in municipal securities in the
lower rating categories, the achievement of the Fund's goals is more dependent
on Scudder Kemper's investment analysis than would be the case if the Fund were
investing exclusively in securities in the higher rating categories.

                                       11
<PAGE>   16

     Scudder Kemper will buy and sell securities for the Fund's portfolio with a
view to seek a high level of current income exempt from federal income tax and
select securities which Scudder Kemper believes do not involve undue risk to
income or principal considered in relation to the particular investment policies
of the Fund. As a result, the Fund does not necessarily invest in the highest
yielding tax-exempt municipal securities permitted by its investment policies if
Scudder Kemper determines that market risks or credit risks associated with such
investments would subject the Fund's portfolio to excessive risk. The potential
for realization of capital gains resulting from possible changes in interest
rates is a consideration. Scudder Kemper will be free to take full advantage of
the entire range of maturities offered by municipal securities and may adjust
the average maturity of the Fund's portfolio from time to time, depending on its
assessment of the relative yields available on securities of different
maturities and its expectations of future changes in interest rates.

ADDITIONAL INVESTMENT PRACTICES

     In connection with the investment objectives and policies described above,
the Fund may: purchase and sell options on municipal securities and on indices
based on municipal securities; engage in interest rate and other hedging
transactions; purchase and sell municipal securities on a "when issued" or
"forward delivery" basis; enter into repurchase agreements; invest in
zero-coupon bonds; and invest in inverse floaters. These investment practices,
which are described below and in the SAI, entail risks and may be changed
without shareholder approval. However, these practices may be limited by certain
conditions imposed in connection with the rating of the Municipal Preferred
shares.

     Securities Options Transactions.  At times, the Fund may engage in any of
the following strategies for hedging purposes with the goal of preserving
capital rather than as a means of enhancing income.


     The Fund may engage in options transactions on municipal securities, which
may be listed for trading on a national securities exchange or traded
over-the-counter. The Fund may write (sell) covered call options and secured put
options on up to 25% of its net assets and may purchase put and call options
provided that no more than 5% of its net assets may be invested in premiums on
such options. The Securities and Exchange Commission requires that obligations
of investment companies such as the Fund, in connection with option sale
positions, must comply with certain segregation or cover requirements mandated
by the SEC.


     A call option gives the purchaser the right to buy, and the writer the
obligation to sell, the underlying security at the agreed upon exercise (or
"strike") price during the option period. A put option gives the purchaser the
right to sell, and the writer the obligation to buy, the underlying security at
the strike price during the option period. Purchasers of options pay an amount,
known as a premium, to the option writer in exchange for the right under the
option contract.

     The Fund may purchase put and call options in hedging transactions to
protect against a decline in the market value of municipal securities in the
Fund's portfolio (e.g., by the purchase of a put option) and to protect against
an increase in the cost of municipal securities that the Fund may seek to
purchase in the future (e.g., by the purchase of a call option). In the event
the Fund purchases put and call options, paying premiums therefor, and price
movements in the underlying securities are such that exercise of the options
would not be profitable for the Fund to the extent such underlying securities
correlate in value to the Fund's portfolio securities, losses of the premiums
paid may be offset by an increase in the value of the Fund's portfolio
securities (in the case of a purchase of put options) or by a decrease in the
cost of acquisition of securities by the Fund (in the case of a purchase of call
options).

     Over-the-counter options ("OTC options") differ from exchange-traded
options in several respects. They are transacted directly with dealers and not
with a clearing corporation, and there is a risk of non-performance by the
dealer. OTC options are available for a greater variety of securities and for a
wider range of expiration dates and exercise prices than for exchange-traded
options. Because OTC options are not traded on an exchange, pricing is normally
done by reference to information from a market maker, which information will be
carefully monitored by Scudder Kemper and verified in appropriate cases.

                                       12
<PAGE>   17

     It will generally be the Fund's policy, in order to avoid the exercise of
an option sold by it, to cancel its obligation under the option by entering into
a closing purchase transaction, if available, unless it is determined to be in
the Fund's interest to sell (in the case of a call option) or to purchase (in
the case of a put option) the underlying securities. A closing purchase
transaction consists of the Fund purchasing an option having the same terms as
the option sold by the Fund and has the effect of canceling the Fund's position
as a seller. The premium which the Fund will pay in executing a closing purchase
transaction may be higher than the premium received when the option was sold,
depending in large part upon the relative price of the underlying security at
the time of each transaction. To the extent options sold by the Fund are
exercised and the Fund either delivers portfolio securities to the holder of a
call option or liquidates securities in its portfolio as a source of funds to
purchase securities put to the Fund, the Fund's portfolio turnover rate may
increase, resulting in a possible increase in short term capital gains and a
possible decrease in long term capital gains.

     During the option period the Fund, as a covered call writer, gives up the
potential appreciation above the exercise price should the underlying security
rise in value, and the Fund, as a secured put writer, retains the risk of loss
should the underlying security decline in value. For the covered call writer,
substantial appreciation in the value of the underlying security would result in
the security being "called away" at the strike price of the option which may be
substantially below the fair market value of such security. For the secured put
writer, substantial depreciation in the value of the underlying security would
result in the security being "put to" the writer at the strike price of the
option which may be substantially in excess of the fair market value of such
security. If a covered call option or a secured put option expires unexercised,
the writer realizes a gain, and the buyer a loss, in the amount of the premium.

     As part of its options transactions the Fund may also use index options,
subject to the limitation that the Fund may write (sell) options on up to 25% of
its net assets and may purchase put and call options without regard to any
percentage limitation. Indices on which the Fund may purchase and sell options
include indices on municipal securities. Through the writing or purchase of
index options the Fund can achieve many of the same objectives as through the
use of options on individual securities. Options on securities indices are
similar to options on securities except that, rather than the right to take or
make delivery of a security at a specified price, an option on a securities
index gives the holder the right to receive, upon exercise of the option, an
amount of cash if the closing level of the securities index upon which the
option is based is greater than, in the case of a call, or less than, in the
case of a put, the strike price of the option. If no active secondary market
exists for any index with respect to which the Fund purchases or sell options,
such options will be treated as illiquid securities for purposes of the Fund's
investment restrictions.

     Price movements in securities which the Fund owns or intends to purchase
will not correlate perfectly with movements in the level of an index and,
therefore, the Fund bears the risk of a loss on an index option which is not
completely offset by movements in the price of such securities. Because index
options are settled in cash, a call writer cannot determine the amount of its
settlement obligations in advance and, unlike call writing on specific
securities, cannot provide in advance for, or cover, its potential settlement
obligations by acquiring and holding the underlying securities.

     Interest Rate and Other Hedging Transactions.  In order to protect the
value of its portfolio securities against declines resulting from changes in
interest rates or other market changes, the Fund may enter into various hedging
transactions, such as financial futures contracts and related options contracts.

     The Fund may enter into various interest rate hedging transactions using
financial instruments with a high degree of correlation to the fixed income
securities which the Fund may purchase for its portfolio, including interest
rate futures contracts in such financial instruments (e.g., futures contracts in
U.S. Treasury securities) and interest rate related indices (municipal bond
indices), put and call options on such futures contracts and on such financial
instruments. The Fund expects to enter into these transactions to "lock in" a
return or spread on a particular investment or portion of its portfolio, to
protect against any increase in the price of securities the Fund anticipates
purchasing at a later date, or for other risk management strategies.

                                       13
<PAGE>   18


     The Fund will not engage in the foregoing transactions for speculative
purposes, but only as a means to hedge risks associated with management of the
Fund's portfolio. These risks include the Fund's relative overall interest rate
risk exposure based on the Fund's current average dollar-weighted maturity and
expectations of Scudder Kemper as to the future direction of changes in interest
rates. Typically, investment in these contracts requires the Fund to deposit
with the applicable exchange or other specified financial intermediary as a good
faith deposit for its obligations an amount of cash or liquid portfolio
securities which initially is 1-3% of the face amount of the contract and which
thereafter fluctuates on a periodic basis as the value of the contract
fluctuates. Thereafter, the Fund must make additional deposits equal to any net
losses due to unfavorable price movements of the contract, and will be credited
with an amount equal to any net gains due to favorable price movements. These
additional deposits or credits are calculated and required daily and are known
as "variation margin."


     The SEC generally requires that when investment companies, such as the
Fund, effect transactions of the foregoing nature, such investment companies
must either segregate cash or liquid portfolio securities in the amount of their
obligations under the foregoing transactions, or cover such obligations by
maintaining positions in portfolio securities, futures contracts or options that
would serve to satisfy or offset the risk of such obligations. When effecting
transactions of the foregoing nature, the Fund will comply with such segregation
or asset cover requirements. There is no limitation as to the percentage of the
Fund's assets which may be invested in such transactions.


     The Fund will typically enter into a futures contract or related option
only if it constitutes a bona fide hedging position under applicable
regulations. Otherwise the Fund will limit its investments in futures contracts
and related options so that, immediately after such investment, the sum of the
amount of its initial margin deposits on open futures contracts and its premiums
on open options contracts will not exceed 5% of the Fund's total assets at
current value.


     All of the foregoing transactions present certain risks. In particular, the
variable degree of correlation between price movements of futures contracts and
price movements in the security being hedged creates the possibility that losses
on the hedge may be greater than gains in the value of the Fund's securities. In
addition, these instruments may not be liquid in all circumstances and are
generally closed out by entering into offsetting transactions rather than by
disposing of the obligations. As a result, in volatile markets, the Fund may not
be able to close out a transaction without incurring losses. Although the
contemplated use of these contracts should tend to reduce the risk of loss due
to a decline in the value of the hedged security, at the same time the use of
these contracts could tend to limit any potential gain which might result from
an increase in the value of such security. Finally, the daily deposit
requirements in futures contracts create an ongoing greater potential financial
risk than do option purchase transactions, where the exposure is limited to the
cost of the premium for the option.

     Successful use of futures contracts and options thereon by the Fund is
subject to the ability of Scudder Kemper to predict correctly movements in the
direction of interest rates and other factors affecting markets for securities.
If the expectations of Scudder Kemper are not met, the Fund would be in a worse
position than if a hedging strategy had not been pursued. For example, if the
Fund has hedged against the possibility of an increase in interest rates which
would adversely affect the price of securities in its portfolio and the price of
such securities increases instead, the Fund will lose part or all of the benefit
of the increased value of its securities because it will have offsetting losses
in its futures position. In addition, in such situations, if the Fund has
insufficient cash to meet daily variation margin requirements, it may have to
sell securities to meet such requirements. Such sales of securities may be, but
will not necessarily be, at increased prices which reflect the rising market.
The Fund may have to sell securities at a time when it is disadvantageous to do
so.

     In addition to engaging in transactions utilizing options on futures
contracts, the Fund may purchase put and call options on securities and, as
developed from time to time, on interest indices and other instruments.
Purchasing options may increase investment flexibility and improve total return,
but also risk loss of the option premium if an asset the Fund has the option to
buy declines in value or if an asset the Fund has the option to sell increases
in value.

                                       14
<PAGE>   19

     New options and futures contracts and various combinations thereof continue
to be developed and the Fund may invest in any such options and contracts as may
be developed to the extent consistent with its investment objective and
regulatory requirements applicable to investment companies.

     Income earned or deemed to be earned, if any, by the Fund from its hedging
activities will be taxable income of the Fund.

     When Issued and Forward Delivery Securities.  Securities may be purchased
on a "when issued" or on a "forward delivery" basis, which means that the
obligations will be delivered at a future date beyond customary settlement time.
The commitment to purchase a security for which payment will be made on a future
date may be deemed a separate security. Although the Fund is not limited in the
amount of securities for which it may have commitments to purchase on such
basis, it is expected that in normal circumstances, the Fund will not commit
more than 30% of its total assets to such purchases. The Fund does not pay for
or start earning interest on the securities until they are received. In order to
invest its assets immediately, while awaiting delivery of securities purchased
on such basis, the Fund will normally invest in shorter term securities that
offer same-day settlement and earnings, but that may bear interest at a lower
rate than longer term securities.

     These transactions are subject to market fluctuation, the value of the
securities at delivery may be more or less than their purchase price, and yields
generally available on comparable securities when delivery occurs may be higher
than yields on the securities obtained pursuant to such transactions. Because
the Fund relies on the buyer or seller, as the case may be, to consummate the
transaction, failure by the other party to complete the transaction may result
in the Fund missing the opportunity of obtaining a price or yield considered to
be advantageous. The Fund makes commitments to purchase securities on such basis
only with the intention of actually acquiring these securities, but the Fund may
sell such securities prior to the settlement date if such sale is considered to
be advisable. To the extent the Fund engages in "when issued" and "forward
delivery" transactions, it will do so for the purpose of acquiring securities
for the Fund's portfolio consistent with the Fund's investment objective and
policies and not for the purpose of investment leverage.

     The SEC generally requires that when investment companies, such as the
Fund, effect transactions of the foregoing nature, such investment companies
must either segregate cash or liquid portfolio securities in the amount of their
obligations under the foregoing transactions, or cover such obligations by
maintaining positions in portfolio securities, futures contracts or options that
would serve to satisfy or offset the risk of such obligations. When effecting
transactions of the foregoing nature, the Fund will comply with such segregation
or asset cover requirements.

     Repurchase Agreements.  In general, the Fund does not engage, nor does it
intend to engage in the foreseeable future, in repurchase agreements. The Fund
has the ability, however, pursuant to its investment objective and policies, to
enter into repurchase agreements (a purchase of, and a simultaneous commitment
to resell, a financial instrument at an agreed upon price on an agreed upon
date) only with member banks of the Federal Reserve System, member firms of the
New York Stock Exchange ("NYSE") or other entities determined by the Adviser to
be creditworthy. When participating in repurchase agreements, the Fund buys
securities from a vendor, e.g., a bank or brokerage firm, with the agreement
that the vendor will repurchase the securities at a higher price at a later
date. The Fund may be subject to various delays and risks of loss if the vendor
is unable to meet its obligation to repurchase. Under the 1940 Act, repurchase
agreements are deemed to be collateralized loans of money by the Fund to the
seller. In evaluating whether to enter into a repurchase agreement, the Adviser
will consider carefully the creditworthiness of the vendor. If the member bank
or member firm that is the party to the repurchase agreement petitions for
bankruptcy or otherwise becomes subject to the U.S. Bankruptcy Code, the law
regarding the rights of the Fund to enforce the terms of the repurchase
agreement is unsettled. The securities underlying a repurchase agreement will be
marked to market every business day so that the value of the collateral is at
least equal to the value of the loan, including the accrued interest thereon,
and the Adviser will monitor the value of the collateral.

                                       15
<PAGE>   20

     Zero-Coupon Bonds.  The Fund may invest in zero-coupon bonds, whose values
are subject to greater fluctuation in response to changes in market interest
rates than bonds that pay interest currently. Zero-coupon bonds are issued at a
significant discount from face value and pay interest only at maturity rather
than at intervals during the life of the security.

     Inverse Floaters.  The Fund may invest in inverse floaters, also called
residual interest municipal bonds, whose interest rates bear an inverse
relationship to the interest rate on another security or the value of an index.
Because changes in the interest rate on the other security or index inversely
affect the residual interest paid on the inverse floater, the value of an
inverse floater is generally more volatile than that of a fixed rate bond.
Inverse floaters tend to underperform the market for fixed rate bonds in a
rising interest rate environment, but tend to outperform the market for fixed
rate bonds when interest rates decline. Although generally volatile, inverse
floaters typically offer the potential for yields exceeding the yields available
on fixed rate bonds with comparable credit quality, coupons, call provisions,
and maturities.

PRINCIPAL INVESTMENT RISKS


     Auction Risk.  Shares of Municipal Preferred may not be transferable at an
auction if the auction fails; that is if there are more shares of Municipal
Preferred offered for sale than there are buyers for those shares. Also if hold
orders are placed at an auction only at a specified rate, and that bid rate
exceeds the rate set at the auction, Municipal Preferred shares will not be
retained by the holders who placed those hold orders. Finally, if Municipal
Preferred shares are bought or elected to be retained without specifying a
minimum rate to continue to hold, and the auction sets a below-market rate, a
rate of return lower than the market rate may be received on Municipal Preferred
shares.


     Call Risk.  If interest rates fall, it is possible that issuers of callable
bonds with high interest coupons will "call" (or prepay) their bonds before
their maturity date. If a call were exercised by the issuer during a period of
declining interest rates, the Fund is likely to replace such called security
with a lower yielding security.

     Credit Risk.  Municipal securities are subject to the risk of non-payment
of scheduled interest and/or principal. Such non-payment would result in a
reduction of income to the Fund and a reduction in the value of the security
experiencing non-payment. Securities rated below investment grade or unrated
securities of comparable quality ("lower quality securities") are subject to the
risk of an issuer's inability to meet principal and interest payments on the
obligations ("credit risk") and may also be subject to price volatility due to
such factors as interest rate sensitivity, market perception of the
creditworthiness of the issuer and general market liquidity ("market risk"). The
prices of lower quality securities are also more likely to react to real or
perceived developments affecting market and credit risk than are prices of
investment grade quality securities ("higher quality securities"), which react
primarily to movements in the general level of interest rates. The investments
in the Fund's portfolio will have speculative characteristics.

     As indicated above, the Fund may invest up to 50% of its total assets in
municipal securities rated below investment grade or unrated municipal
securities which, in the opinion of Scudder Kemper, have equivalent credit
characteristics and are of comparable quality. The Fund will not purchase
municipal securities rated lower than B- by S&P or B by Moody's or unrated
municipal securities, which in the opinion of Scudder Kemper, have equivalent
credit characteristics and are of comparable quality. Such obligations are
commonly called "junk bonds" and will have speculative characteristics in
varying degrees. While such obligations may have some quality and protective
characteristics, these characteristics can be expected to be offset or
outweighed by uncertainties or major risk exposures to adverse conditions.
Scudder Kemper seeks to minimize the risks of investing in below investment
grade securities through professional investment analysis, attention to current
developments in interest rates and economic conditions, and industry and
geographic diversification (if practicable). When the Fund invests in lower
rated or unrated municipal securities, the achievement of the Fund's goals is
more dependent on Scudder Kemper's ability than would be the case if the Fund
were investing in municipal securities in the higher rating categories. In
evaluating the credit quality of a particular issue, whether rated or unrated,
Scudder Kemper will

                                       16
<PAGE>   21

normally take into consideration, among other things, the financial resources of
the issuer (or, as appropriate, of the underlying source of funds for debt
service), its sensitivity to economic conditions and trends, any operating
history of and the community support for the facility financed by the issue, the
ability of the issuer's management and regulatory matters. Scudder Kemper will
attempt to reduce the risks of investing in the lowest investment grade, below
investment grade and comparable unrated obligations through active portfolio
management, credit analysis and attention to current developments and trends in
the economy and the financial markets.

     Increases in interest rates and changes in the economy may adversely affect
the ability of issuers of lower grade municipal securities to pay interest and
to repay principal, to meet projected financial goals and to obtain additional
financing. In the event that an issuer of securities held by the Fund
experiences difficulties in the timely payment of principal or interest and such
issuer seeks to restructure the terms of its borrowings, the Fund may incur
additional expenses and may determine to invest additional assets with respect
to such issuer or the project or projects to which the Fund's portfolio
securities relate. Further, the Fund may incur additional expenses to the extent
that it is required to seek recovery upon a default in the payment of interest
or the repayment of principal on its portfolio holdings, and the Fund may be
unable to obtain full recovery thereof.

     To the extent that there is no established retail market for some of the
lower grade municipal securities in which the Fund may invest, trading in such
securities may be relatively inactive. The Adviser is responsible for
determining the net asset value of the Fund, subject to the supervision of the
Board of Trustees of the Fund. During periods of reduced market liquidity and in
the absence of readily available market quotations for lower grade municipal
securities held in the Fund's portfolio, the ability of the Adviser to value the
Fund's securities becomes more difficult and the Adviser's use of judgment may
play a greater role in the valuation of the Fund's securities due to the reduced
availability of reliable objective data. The effects of adverse publicity and
investor perceptions may be more pronounced for securities for which no
established retail market exists as compared with the effects on securities for
which such a market does exist. Further, the Fund may have more difficulty
selling such securities in a timely manner and at their stated value than would
be the case for securities for which an established retail market does exist.

     Municipal securities held by the Fund that are of below investment grade
quality but which, subsequent to the assignment of such rating, are backed by
escrow accounts containing U.S. Government obligations may be determined by
Scudder Kemper to be of investment grade quality for purposes of the Fund's
investment policies. The Fund may retain in its portfolio an obligation that
declines in quality, including defaulted obligations, if such retention is
considered desirable by Scudder Kemper. In the case of a defaulted obligation,
the Fund may incur additional expense seeking recovery of its investment.

     Changes in the credit quality of the issuers of municipal securities held
by the Fund will affect the principal value of (and possibly the income earned
on) such obligations. In addition, the value of such securities are affected by
changes in general economic conditions and business conditions affecting the
relevant economic sectors. Changes by rating agencies in their ratings of a
security and in the ability of the issuer to make payments of principal and
interest may also affect the value of the Fund's investments. The amount of
information about the financial condition of an issuer of municipal securities
may not be as extensive as that made available by corporations whose securities
are publicly traded.

     The Fund may invest in municipal leases, and participations in municipal
leases. The obligation of the issuer to meet its obligations under such leases
is often subject to the appropriation by the appropriate legislative body, on an
annual or other basis, of funds for the payment of the obligations. Investments
in municipal leases are thus subject to the risk that the legislative body will
not make the necessary appropriation and the issuer will not otherwise be
willing or able to meet its obligation.

     Income Risk.  The Fund's income is based primarily on the interest it earns
from its investments, which can vary widely over the short- and long-term. If
interest rates drop, the Fund's income available over time to make dividend
payments with respect to the Municipal Preferred shares could drop as well if

                                       17
<PAGE>   22

the Fund purchases securities with lower interest coupons. This risk is
magnified when prevailing short-term interest rates increase and the Fund holds
inverse floaters.

     Inflation Risk.  Inflation is the reduction in the purchasing power of
money resulting from the increase in the price of goods and services. Inflation
risk is the risk that the inflation adjusted (or "real") value of a Municipal
Preferred investment or the income from that investment will be worth less in
the future. As inflation occurs, the real value of the shares of Municipal
Preferred and distributions declines. In an inflationary period, however, it is
expected that, through the auction process, dividend rates on Municipal
Preferred shares would increase, tending to offset this risk.

     Interest Rate and Market Risk.  The prices of municipal securities tend to
fall as interest rates rise. Securities that have longer maturities tend to
fluctuate more in price in response to changes in market interest rates than do
securities with shorter maturities. This risk is usually greater among municipal
securities with longer maturities or durations and when inverse floaters are
held by the Fund. Although the Fund has no policy governing the maturities or
durations of its investments, the Fund expects that it will invest in a
portfolio of longer-term securities. This means that the Fund will be subject to
greater market risk (other things being equal) than a fund investing solely in
shorter-term securities. Market risk is often greater among certain types of
income securities, such as zero-coupon bonds, which do not make regular interest
payments. As interest rates change, these bonds often fluctuate in price more
than higher quality bonds that make regular interest payments. Because the Fund
may invest in these types of income securities, it may be subject to greater
market risk than a fund that invests only in current interest paying securities.

     The Fund may invest in inverse floaters. Compared to similar fixed rate
municipal bonds, the value of these bonds will fluctuate to a greater extent in
response to changes in prevailing long-term interest rates. Moreover, the income
earned on inverse floaters will fluctuate in response to changes in prevailing
short-term interest rates. Thus, when such bonds are held by the Fund, an
increase in short- or long-term market interest rates will adversely affect the
income received from such bonds.

     Non-Diversification Risk.  The Fund has registered as a "non-diversified"
investment company under the 1940 Act so that, subject to its investment
restrictions and applicable federal income tax diversification requirements,
with respect to 50% of its total assets, it will be able to invest more than 5%
(but not more than 25%) of the value of its total assets in the obligations of
any single issuer. To the extent the Fund invests a relatively high percentage
of its assets in obligations of a limited number of issuers, the Fund will be
more susceptible than a more widely diversified investment company to any single
corporate, economic, political or regulatory occurrence.


     Ratings and Asset Coverage Risk.  While Moody's and S&P assign ratings of
aaa or AAA to Municipal Preferred shares, the ratings do not eliminate or
necessarily mitigate the risks of investing in Municipal Preferred shares. A
rating agency could downgrade Municipal Preferred shares, which may make the
shares less liquid at an auction or in the secondary market, though probably
with higher resulting dividend rates. If a rating agency downgrades Municipal
Preferred shares, or if the asset coverage for Municipal Preferred shares
declines to less than 200%, the Fund is required to alter its portfolio or
redeem Municipal Preferred shares. The Fund may voluntarily redeem Municipal
Preferred shares under certain circumstances.



     Secondary Market Risk.  At times, a substantial portion of the Fund's
assets may be invested in securities that are held by a relatively limited
number of institutional investors, including the Fund and various accounts
managed by Scudder Kemper. Given the relatively limited number of holders of
such securities, under adverse market or economic conditions or in the event of
adverse changes in the financial condition of the issuer, the Fund could find it
more difficult to sell such securities when Scudder Kemper believes it advisable
to do so or may be able to sell such securities only at prices lower than if
such securities were more widely held. In such circumstances, it may also be
more difficult to determine the fair value of such securities for purposes of
computing the Fund's net asset value.


                                       18
<PAGE>   23

     If Municipal Preferred shares are attempted to be sold between auctions,
any or all of the shares may not be able to be sold, or they may not be able to
be sold for $25,000 per share or $25,000 per share plus accumulated dividends.
If the Fund has designated a special dividend period, changes in interest rates
could affect the price on shares sold in the secondary market. Broker-dealers
that maintain a secondary market for Municipal Preferred shares are not required
to maintain this market, and the Fund is not required to redeem shares either if
an auction or an attempted secondary market sale fails because of lack of
buyers. Municipal Preferred shares are not registered on a stock exchange or on
the National Association of Securities Dealers Automated Quotations System
("NASDAQ") stock market. If Municipal Preferred shares are sold to a
broker-dealer between auctions, the sale price of the shares sold may be less
than their original purchase price, especially when market interest rates have
risen since the last auction. Accrued Municipal Preferred dividends, however,
should at least partially compensate for the increased market interest rates.

     Year 2000 Risk.  Like other registered investment companies and financial
business organizations worldwide, the Fund could be adversely affected if
computer systems on which the Fund relies, which primarily include those used by
the Adviser, its affiliates or other service providers, are unable to correctly
process date-related information on and after January 1, 2000. This risk is
commonly called the Year 2000 (Y2K) Issue. Failure to successfully address the
Y2K Issue could result in interruptions to and other material adverse effects on
the Fund's business and operations. The Adviser has commenced a review of the
Y2K Issue as it may affect the Fund and is taking steps it believes are
reasonably designed to address the Y2K Issue, although there can be no
assurances that these steps will be sufficient. In addition, there can be no
assurances that the Y2K Issue will not have any adverse effect on the issuers
whose securities are held by the Fund or on global markets or economies
generally.

                        DETERMINATION OF NET ASSET VALUE

     Net asset value of the Fund will be determined as of the close of regular
trading on the NYSE (generally 4:00 p.m. Eastern time) on the last business day
of each week (generally Friday), and at such other times as the Fund may
authorize. The net asset value of the Fund equals the value of the Fund's assets
less the Fund's liabilities. Portfolio securities for which market quotations
are readily available are valued at current market value. Short-term investments
maturing in 60 days or less are valued at amortized cost when the Adviser
determines, pursuant to procedures adopted by the Board of Trustees, that such
cost approximates current market value. All other securities and assets are
valued at their fair value following procedures adopted by the Board of
Trustees.

                                  THE AUCTION

SUMMARY OF AUCTION PROCEDURES


     The following is a brief summary of the auction procedures. See the SAI for
a full description of the auction procedures. The auction determines the
applicable rate (the dividend rate) for Municipal Preferred shares, but the
applicable rate will not be higher than the maximum rate. See "Description of
Municipal Preferred -- Dividends and Dividend Periods." You also may buy or sell
shares of Municipal Preferred in the auction.



     If you own shares of Municipal Preferred, you may instruct, orally or in
writing, a broker-dealer to enter an order in the auction. Existing Municipal
Preferred shareholders can enter three kinds of orders regarding their Municipal
Preferred shares: sell, bid, and hold.



     - If you enter a sell order, you indicate that you want to sell shares of
       Municipal Preferred at $25,000 per share, no matter what the next rate
       period's applicable rate will be.



     - If you enter a bid (or "hold at a rate") order, you indicate that you
       want to sell shares of Municipal Preferred only if the next rate period's
       applicable rate is less than the rate you specify.



     - If you enter a hold order, you indicate that you want to continue to own
       shares of Municipal Preferred, no matter what the next rate period's
       applicable rate will be.



     You may enter different types of orders for your Municipal Preferred
shares, as well as orders for additional Municipal Preferred shares. All orders
must be for whole shares. All orders you submit are irrevocable. There are a
fixed number of Municipal Preferred shares, and the applicable rate likely will
vary from auction to auction depending on the number of bidders, the number of
shares the bidders seek to buy, and general economic conditions including
current interest rates. If you own Municipal Preferred shares and submit a bid
higher than the maximum rate, your bid will be treated as a sell order. If you
do not enter an order, the broker-dealer will assume that you want to continue
to hold Municipal Preferred shares, but if you fail to submit an order and the
rate period is longer than 28 days, the broker-dealer will treat your failure to
submit a bid as a sell order.



     If you do not currently own shares of Municipal Preferred, or want to buy
more shares, you may instruct a broker-dealer to enter a bid order to buy shares
in an auction at $25,000 per share at or above a specified dividend rate. If
your bid specifies a rate higher than the maximum rate, your order will not be
accepted.



     Broker-dealers will submit orders from existing and potential shareholders
to the auction agent. Neither the Fund nor the auction agent will be responsible
for a broker-dealer's failure to submit orders from existing shareholders and
potential shareholders. A broker-dealer's failure to submit orders for Municipal
Preferred shares held by it or its customers will be treated in the same manner
as a shareholder's failure to submit an order to the broker-dealer. A
broker-dealer may submit orders to the auction agent for its own account
provided it is not an affiliate of the Fund.



     The auction agent after each auction for shares of Municipal Preferred will
pay to each broker-dealer, from funds provided by the Fund, a service charge at
the annual rate of 1/4 of 1% in the case of any auction immediately preceding a
rate period of less than one year, or a percentage agreed to by the Fund and the
broker-dealers, in the case of any auction immediately preceding a rate period
of one year or longer, of the purchase price of shares of Municipal Preferred
placed by the broker-dealers at the auction.



     If the number of Municipal Preferred shares subject to bid orders with a
dividend rate equal to or lower than the maximum rate for shares of Municipal
Preferred is at least equal to the number of Municipal Preferred shares subject
to sell orders, then the applicable rate for the next rate period will be the
lowest rate submitted which, taking into account that rate and all lower rates
submitted in order from existing and potential shareholders, would result in
existing and potential shareholders owning all the Municipal Preferred shares
available for purchase in the auction.


                                       20
<PAGE>   25


     If the number of Municipal Preferred shares subject to bid orders with a
dividend rate equal to or lower than the maximum rate for shares of Municipal
Preferred is less than the number of Municipal Preferred shares subject to sell
orders, then the auction is considered to be a failed auction, and the dividend
rate will be the maximum rate. In that event, existing shareholders that have
submitted sell orders (or are treated as having submitted sell orders) may not
be able to sell any or all of the shares for which they submitted sell orders.



     The auction agent will not accept a bid above the maximum rate. The purpose
of the maximum rate is to place an upper limit on Municipal Preferred dividends
and in so doing to help protect the earnings available to pay common share
dividends, and to serve as the applicable rate in the event of a failed auction
(that is, an auction where there are more Municipal Preferred shares offered for
sale than there are buyers for those shares).



     If the Fund plans to include any net capital gains or other federal taxable
income in a Municipal Preferred dividend, it generally will notify the auction
agent of the amount to be included at least a week before the next dividend
payment date for the rate period in which taxable income will be included in the
dividend. The auction agent will notify broker-dealers, who in turn will notify
their customers.



     If broker-dealers submit or are deemed to submit hold orders for all
outstanding shares of Municipal Preferred, that is considered an "all hold"
auction and the applicable rate for the next rate period will be the all hold
order rate. The "all hold order rate" is the lesser of the S&P Kenny 30-day High
Grade Index (if the rate period is less than 183 days) or the product of:



          (1)(a) the "AA" Composite Commercial Paper Rate (the interest
     equivalent of rates applicable to AA-rated securities for time periods that
     vary depending on the applicable rate period) on the auction date for that
     rate period if the rate period is less than 183 days, (b) the Treasury Bill
     Rate (the bond equivalent yield of the current rate on a Treasury Bill with
     a remaining maturity closest to the length of the applicable rate period)
     on the auction date for that rate period if the rate period is greater than
     182 days but less than 365 days, or (c) the Treasury Note Rate (the current
     yield on a Treasury Note with a remaining maturity closest to the length of
     the applicable rate period) on the auction date for that rate period if the
     rate period is greater than 364 days; and


          (2) 1 minus the greater of the maximum marginal regular federal
     individual income tax rate applicable to ordinary income or the maximum
     marginal regular federal corporate income tax rate.


If taxable income is allocated to the Municipal Preferred shares during a
particular auction period, the interest rate may be adjusted to compensate for
the tax allocation.



     The auction procedures include a pro rata allocation of shares for purchase
and sale. This allocation process may result in an existing shareholder
continuing to hold or selling, or a potential shareholder buying, fewer shares
than the number of shares in its order. If this happens, broker-dealers will be
required to make appropriate pro rata allocations among their customers.



     Settlement of purchases and sales will be made on the next business day
(which also is a dividend payment date) after the auction date through The
Depository Trust Company. Purchasers will pay for their shares through
broker-dealers in same-day funds to The Depository Trust Company against
delivery to the broker-dealers. The Depository Trust Company will make payment
to the sellers' broker-dealers in accordance with its normal procedures, which
require broker-dealers to make payment against delivery in same-day funds.
Throughout this Prospectus, a business day is a day on which the NYSE is open
for trading, and which is neither a Saturday, Sunday nor any other day on which
banks in New York, New York are authorized by law to close.


     The first auction for shares of Municipal Preferred will be held on
Tuesday,           , 1999, the business day preceding the dividend payment date
for the initial rate period. Thereafter, except during special rate periods,
auctions will normally be held every Tuesday, and each subsequent rate period
will normally begin on the following Wednesday.

     The following is a simplified example of how a typical auction works.
Assume that the Fund has 1,000 outstanding shares of Municipal Preferred, and
three current shareholders. The three current shareholders and three potential
shareholders submit orders through broker-dealers at the auction:

</TABLE>


     The lowest dividend rate that will result in all 1,000 shares of Municipal
Preferred continuing to be held is 3.4% (the offer by D). Therefore, the
applicable rate will be 3.4%. Current shareholders B and C will continue to own
their shares. Current shareholder A will sell its shares because A's dividend
rate bid was higher than the applicable rate. Potential shareholder D will buy
200 shares and Potential shareholder E will buy 300 shares, both because their
bid rates were at or below the applicable rate. Potential shareholder F will not
buy any shares because its bid rate was above the applicable rate.


SECONDARY MARKET TRADING AND TRANSFER OF MUNICIPAL PREFERRED


     The broker-dealers (including the underwriter) expect, but are not
obligated, to maintain a secondary trading market in shares of Municipal
Preferred outside of auctions. There can be no assurance that a secondary
trading market for shares of Municipal Preferred will develop or, if it does
develop, that it will provide owners with liquidity of investment. The shares of
Municipal Preferred will not be registered on any stock exchange or on the
NASDAQ stock market. Investors who purchase shares of Municipal Preferred in an
auction for a special rate period should note that because the dividend rate on
such shares will be fixed for the length of that rate period, the value of such
shares may fluctuate in response to the changes in interest rates, and may be
more or less than their original cost if sold on the open market in advance of
the next auction thereof, depending on market conditions.



     An existing shareholder may sell, transfer, or otherwise dispose of shares
of Municipal Preferred only in whole shares and only (1) pursuant to a bid or
sell order placed with the auction agent in accordance with the auction
procedures, (2) to a broker-dealer or (3) to such other persons as may be
permitted by the Fund; provided, however, that (a) a sale, transfer or other
disposition of shares of Municipal Preferred from a customer of a broker-dealer
who is listed on the records of that broker-dealer as the holder of such shares
to that broker-dealer or another customer of that broker-dealer shall not be
deemed to be a sale, transfer or other disposition for purposes of the foregoing
if such broker-dealer remains the existing shareholder of the shares so sold,
transferred or disposed of immediately after such sale, transfer or disposition
and (b) in the case of all transfers other than pursuant to auctions, the
broker-dealer (or other person, if permitted by the Fund) to whom such transfer
is made shall advise the auction agent of such transfer.

                       DESCRIPTION OF MUNICIPAL PREFERRED

GENERAL

     The following is a brief description of the terms of the shares of
Municipal Preferred. For the complete terms of the Municipal Preferred, you may
refer to the Fund's Certificate filed as an exhibit to the Fund's registration
statement on Form N-2.


     Under the Declaration of Trust, the Fund is authorized to issue an
unlimited number of preferred shares. The Fund's Certificate authorizes the
issuance of up to 5,000 shares of Municipal Preferred. Municipal Preferred
shares will have a liquidation preference of $25,000 per share, plus an amount
equal to accumulated dividends. Municipal Preferred shares, when issued and
sold, will be fully paid and nonassessable by the Fund, will not by their terms
be convertible into or exchangeable for shares of another class and will have no
preemptive rights. Shares of Municipal Preferred will not be subject to any
sinking fund, but will be subject to mandatory redemption under the certain
circumstances described below.


DIVIDENDS AND DIVIDEND PERIODS


     General.  The following is a general description of dividends and rate
periods. See the SAI for a more detailed discussion of this topic.



     The dividend rate for the initial rate period for Municipal Preferred
shares will be the rate set out on the cover of the Prospectus. For subsequent
rate periods, Municipal Preferred shares will pay dividends based on a rate set
at the auction, normally held weekly, but the rate set at the auction will not
exceed the maximum rate. Rate periods generally will be seven days, and a rate
period will begin on the first business day after the auction. In most
instances, dividends are also paid weekly, on the day following the end of the
rate period. The Fund, subject to some limitations, may change the length of
rate periods, designating them as "special rate periods." See "-- Designation of
Special Rate Periods."


     Dividend Payments.  Except as provided below, the dividend payment date
will be the day after the rate period ends. If the Wednesday on which the
Municipal Preferred normally pays dividends is not a business day, then the
dividends will be paid on the first business day that falls after that
Wednesday. The Fund may specify different dividend payment dates in respect of
any special rate period of more than 28 rate periods days. See "-- Designation
of Special Rate Periods" for a discussion of payment dates for a special rate
period.

     Dividends on Municipal Preferred shares will be paid on the dividend
payment date to holders of record as their names appear on the Fund's record
books on the business day next preceding the dividend payment date. If dividends
are in arrears, they may be declared and paid at any time to holders of record
as their names appear on the Fund's record books on that date, not more than 15
days before the payment date, as the Fund's Board of Trustees may fix.


     The Depository Trust Company, in accordance with its current procedures, is
expected to credit on each dividend payment date dividends received from the
Fund to the accounts of broker-dealers who act on behalf of Municipal Preferred
shareholders. Such broker-dealers, in turn, are expected to distribute dividend
payments to the person for whom they are acting as agents. The initial
broker-dealer, Salomon Smith Barney Inc., however, has indicated to the Fund
that it or the broker-dealer it designates will make these dividend payments
available in same-day funds, rather than next-day funds, on each dividend
payment date to customers that use that broker-dealer. A Municipal Preferred
shareholder that does not use an initial broker-dealer, or one of its
affiliates, should contact his or her broker-dealer to determine whether it will
make dividend payments available to the shareholder in same-day or next-day
funds. If a broker-dealer does not make dividends available to Municipal
Preferred shareholders in same-day funds, these shareholders will not have funds
available until the next business day.


     Dividend Rate Set at Auction.  Municipal Preferred shares pay dividends
based on a rate set at auction. The auction usually is held weekly, but may be
held less frequently. The auction sets the dividend
                                       23
<PAGE>   28


rate, and Municipal Preferred shares may be bought and sold at the auction.
Bankers Trust Company, the auction agent, reviews orders from broker-dealers on
behalf of existing shareholders that wish to sell or hold at the auction rate,
or hold only at a specified rate, and on behalf of potential shareholders that
wish to buy Municipal Preferred shares. The auction agent then determines the
lowest dividend rate that will result in all of the outstanding Municipal
Preferred shares continuing to be held. The shares in this offering will trade
at auction starting in the week following this offering. See "The Auction."


     Determination of Dividend Rates.  The Fund computes the dividends per share
by multiplying the dividend rate determined at the auction by a fraction, the
numerator of which normally is seven and the denominator of which normally is
365. If the Fund has designated a special rate period, then the numerator is the
number of days in the rate period, and the denominator is 360. In either case,
this rate is then multiplied by $25,000 to arrive at the dividend per share. The
numerator may be different if the rate period includes a holiday.


     If an auction for any subsequent rate period of Municipal Preferred shares
is not held for any reason other than as described below, the dividend rate on
those shares will be the maximum rate on the auction date for that subsequent
rate period.



     Maximum Rate.  The dividend rate that results from an auction for Municipal
Preferred will not be greater than the maximum rate, which is:



          (a) for any auction date which is not the auction date immediately
     prior to the first day of any proposed special rate period, the product of
     (i) the reference rate on that auction date for the next rate period of
     Municipal Preferred shares and (ii) the rate multiple on that auction date,
     unless Municipal Preferred shares have or had a special rate period (other
     than a special rate period of 28 rate period days or fewer) and an auction
     at which sufficient clearing bids existed has not yet occurred after that
     special rate period for a minimum rate period (seven days) in which case
     the maximum rate will be the higher of:


             (A) the dividend rate on Municipal Preferred shares for the
        then-ending rate period, and


             (B) the product of (x) the higher of (I) the reference rate on that
        auction date for a rate period equal in length to the then-ending rate
        period of Municipal Preferred shares, if the then-ending rate period was
        364 rate period days or fewer, or the Treasury Note Rate on that auction
        date for a rate period equal in length to the then-ending rate period of
        Municipal Preferred shares, if the then-ending rate period was more than
        364 rate period days, and (II) the reference rate on that auction date
        for a rate period equal in length to that special rate period of
        Municipal Preferred shares, if that special rate period was 364 rate
        period days or fewer, or the Treasury Note Rate on that auction date for
        a rate period equal in length to that special rate period, if that
        special rate period was more than 364 rate period days and (y) the rate
        multiple on that auction date; or



          (b) for any auction date that is the auction date immediately prior to
     the first day of any proposed special rate period, the product of (i) the
     highest of (x) the reference rate on that auction date for a rate period
     equal in length to the then-ending rate period of Municipal Preferred
     shares, if the then-ending rate period was 364 rate period days or fewer,
     or the Treasury Note Rate on that auction date for a rate period equal in
     length to the then-ending rate period of Municipal Preferred shares, if the
     then-ending rate period was more than 364 rate period days, (y) the
     reference rate on that auction date for the special rate period for which
     the auction is being held if that special rate period is 364 rate period
     days or fewer or the Treasury Note Rate on that auction date for the
     special rate period for which the auction is being held if that special
     rate period is more than 364 rate period days, and (z) the reference rate
     on that auction date for minimum rate periods and (ii) the rate multiple on
     that auction date.



     The "reference rate" is (i) the higher of the Taxable Equivalent of the
Short-Term Municipal Bond Rate (the approximate taxable yield equivalent of the
yield on short-term municipal securities, derived with reference to the S&P
Kenny 30-day High Grade Index) and the "AA" Composite Commercial Paper

                                       24
<PAGE>   29

Rate in the case of minimum rate periods and special rate periods of 28 rate
period days or fewer; (ii) the "AA" Composite Commercial Paper Rate in the case
of special rate periods of more than 28 rate period days but fewer than 183 rate
period days; and (iii) the Treasury Bill Rate in the case of special rate
periods of more than 182 rate period days but fewer than 365 rate period days.


     The Taxable Equivalent of the Short-Term Municipal Bond Rate, "AA"
Composite Commercial Paper Rate, Treasury Bill Rate and Treasury Note Rate will
be the rates announced on the auction date for the business day immediately
before the auction date. The "rate multiple" will be a percentage, determined as
set out below, based on the prevailing rating of Municipal Preferred shares in
effect at the close of business on the business day immediately before the
auction date.


<TABLE>

</TABLE>


     If the Fund has notified the auction agent that it intends to allocate
federal taxable income to Municipal Preferred shares before the auction
establishing the applicable rate for those shares, the applicable percentage in
the table above will be divided by the quantity 1 minus the greater of the
maximum marginal regular federal individual income tax rate applicable to
ordinary income or the maximum marginal regular federal corporate income tax
rate. If the ratings for shares of Municipal Preferred are split between two of
the foregoing categories, the lower rating will determine the prevailing rating.
If only one rating agency is rating Municipal Preferred shares, that agency's
rating will be the prevailing rating.



     The Fund may only pay dividends when and if the Fund's Board of Trustees
declares dividends out of monies legally available for this purpose, at the
applicable rate per year for this purpose and no more (except as described under
"-- Dividends and Dividend Periods -- Gross-Up Payments") payable on the dates
determined as described below. If the Fund does not pay a dividend when the
Board of Trustees declares it, then that dividend will be added to dividends
payable on those Municipal Preferred shares in the future.



     Effect of Failure to Pay Dividends in a Timely Manner.  If the Fund fails
to pay, in a timely manner, the auction agent the full amount of any dividend
on, or the redemption price of, any Municipal Preferred shares during any rate
period (other than any special rate period of more than 364 rate period days or
any rate period succeeding any special rate period of more than 364 rate period
days during which a failure occurred that has not been cured), but the Fund
cures the failure and pays any late charge before 12:00 noon Eastern time on the
third business day following the date the failure occurred, no auction will be
held for Municipal Preferred shares for the first subsequent rate period
thereafter, and the dividend rate for Municipal Preferred shares for that
subsequent rate period will be the maximum rate on the auction date for that
subsequent rate period.



     If the Fund fails to pay, in a timely manner, the auction agent the full
amount of any dividend on, or the redemption price of, any Municipal Preferred
shares during any rate period thereof (other than any special rate period of
more than 364 rate period days or any rate period succeeding any special rate
period of more than 364 rate period days during which a failure occurred that
has not been cured), and the Fund does not cure the failure and pay any late
charge before 12:00 noon Eastern time on the third business day next succeeding
the date on which the failure occurred, no auction will be held for Municipal
Preferred shares for the first subsequent rate period thereafter (or for any
rate period thereafter, to and including the rate period during which the
failure is cured and the late charge is paid) (the late charge is to be paid
only in the event Moody's is rating the shares at the time the Fund cures the
failure), and the dividend rate for Municipal Preferred shares for each such
subsequent rate period will be an annual rate equal to the maximum rate on the
auction date for that subsequent rate period (but with the prevailing rating for
Municipal Preferred, for purposes of determining the maximum rate, being "Below
Ba3/BB-").


                                       25
<PAGE>   30


     If the Fund fails to pay, in a timely manner, the auction agent the full
amount of any dividend on, or the redemption price of, any shares of Municipal
Preferred during a special rate period of more than 364 rate period days, or
during any rate period succeeding any special rate period of more than 364 rate
period days during which a failure occurred that has not been cured, and the
Fund does not cure the failure and pay a late charge, no auction will be held
for Municipal Preferred shares for that subsequent rate period (or for any rate
period thereafter, to and including the rate period during which the failure is
cured and the late charge paid) (the late charge is to be paid only in the event
Moody's is rating Municipal Preferred shares at the time the Fund cures the
failure), and the dividend rate for Municipal Preferred shares for each
subsequent rate period will be an annual rate equal to the maximum rate on the
auction date for each subsequent rate period (but with the prevailing rating for
Municipal Preferred, for purposes of determining the maximum rate, being "Below
Ba3/BB-").



     The Fund cures a failure to pay dividends on shares of Municipal Preferred
for any rate period by paying the auction agent all accumulated and unpaid
dividends on the Municipal Preferred shares.



     Gross-Up Payments.  Holders of shares of Municipal Preferred shall be
entitled to receive, when, as and if declared by the Board of Trustees, out of
funds legally available therefor in accordance with the Declaration of Trust,
the Certificate and applicable law, dividends in an amount equal to the
aggregate Gross-up Payment in accordance with the following:


     If, in the case of any minimum rate period or any special rate period of 28
rate period days or fewer, the Fund allocates any net capital gain or other
income taxable for federal income tax purposes to a dividend paid on shares of
Municipal Preferred without having given advance notice thereof to the auction
agent as described above under "The Auction" (a "Taxable Allocation") solely by
reason of the fact that such allocation is made retroactively as a result of the
redemption of all or a portion of the outstanding shares of Municipal Preferred
or the liquidation of the Fund, the Fund will, prior to the end of the calendar
year in which such dividend was paid, provide notice thereof to the auction
agent and direct the Fund's dividend disbursing agent to send such notice with a
Gross-up Payment to each holder of shares (initially Cede & Co., as nominee of
The Depository Trust Company) that was entitled to such dividend payment with
respect to shares of Municipal Preferred during such calendar year at such
holder's address as the same appears or last appeared on the record books of the
Fund.

     If, in the case of any special rate period of more than 28 rate period
days, the Fund makes a Taxable Allocation to a dividend paid on shares of
Municipal Preferred, the Fund shall, prior to the end of the calendar year in
which such dividend was paid, provide notice thereof to the auction agent and
direct the Fund's dividend disbursing agent to send such notice with a Gross-up
Payment to each holder of such shares that was entitled to such dividend payment
during such calendar year at such holder's address as the same appears or last
appeared on the record books of the Fund.

     The Fund shall not be required to make Gross-up Payments with respect to
any net capital gain or other taxable income determined by the Internal Revenue
Service (the "IRS") to be allocable in a manner different from that allocated by
the Fund.

     A "Gross-up Payment" in respect of any dividend means payment to a holder
of shares of Municipal Preferred of an amount which, giving effect to the
Taxable Allocations made with respect to such dividend, would cause such
holder's after-tax returns (taking into account both the Taxable Allocations and
the Gross-up Payment) to be equal to the after-tax return the holder would have
received if no such Taxable Allocations had occurred. Such Gross-up Payment
shall be calculated: (i) without consideration being given to the time value of
money; (ii) assuming that no holder of shares of Municipal Preferred is subject
to the federal alternative minimum tax with respect to dividends received from
the Fund and (iii) assuming that each holder of shares of Municipal Preferred is
taxable at the maximum marginal regular federal individual income tax rate
applicable to ordinary income or net capital gain, as applicable, or the maximum
marginal regular federal corporate income tax rate applicable to ordinary income
or net capital gain, as applicable, whichever is greater, in effect at the time
such Gross-up Payment is made.

                                       26
<PAGE>   31

     Restrictions on Dividends and Other Distributions.  When the Fund has any
Municipal Preferred shares outstanding, the Fund may not pay any dividend or
distribution (other than a dividend or distribution paid in shares of a series
of, or in options, warrants or rights to subscribe for or purchase, common
shares) in respect of common shares or call for redemption, redeem, purchase or
otherwise acquire for consideration any common shares (except by conversion into
or exchange for shares of the Fund ranking junior to the shares of Municipal
Preferred as to the payment of dividends and the distribution of assets upon
liquidation), unless (1) it has paid all cumulative dividends on Municipal
Preferred shares; (2) it has redeemed any Municipal Preferred shares that it has
called for mandatory redemption; and (3) after paying the dividend, the Fund
meets Moody's and S&P's asset coverage requirements described under "Rating
Agency Guidelines."

     Except as set forth in the next sentence, no dividends shall be declared or
paid or set apart for payment on any class or series of shares of beneficial
interest of the Fund ranking, as to the payment of dividends, on a parity with
shares of Municipal Preferred for any period unless full cumulative dividends
have been or contemporaneously are declared and paid on the shares of Municipal
Preferred through their most recent dividend payment date. When dividends are
not paid in full upon the shares of Municipal Preferred through their most
recent dividend payment date or upon any other class or series of shares ranking
on a parity as to the payment of dividends with shares of Municipal Preferred
through their most recent respective dividend payment dates, all dividends
declared upon shares of Municipal Preferred and any other such class or series
of shares ranking on a parity as to the payment of dividends with shares of
Municipal Preferred shall be declared pro rata so that the amount of dividends
declared per share on shares of Municipal Preferred and such other class or
series of shares shall in all cases bear to each other the same ratio that
accumulated dividends per share on the shares of Municipal Preferred and such
other class or series of shares bear to each other.

DESIGNATION OF SPECIAL RATE PERIODS

     The Fund may instruct the auction agent to hold auctions and pay dividends
less frequently than weekly. The Fund may do this if, for example, the Fund
expects that short-term rates might increase or market conditions otherwise
change, in an effort to optimize the effect of the Fund's leverage on common
shareholders. If the Fund decides to use a special rate period, the special rate
period will consist of a number of days evenly divisible by seven and not more
than 1,820 days (approximately five years), subject to adjustments. The Fund
does not currently expect to hold auctions and pay dividends less frequently
than weekly in the near future. If the Fund designates a special rate period,
changes in interest rates could affect the price received if the shares were
sold in the secondary market.

     Before the Fund designates a special rate period: (1) at least 20 (or such
lesser number of days as may be agreed to from time to time by the auction
agent) and not more than 30 days before the first day of the proposed special
rate period, the Fund must publish a notice of its intention to designate a
special rate period in a newspaper circulated to the financial community in New
York, and must mail a notice to Municipal Preferred shareholders of its intent
to designate a special rate period; (2) the Fund must inform the auction agent
by 11:00 a.m. Eastern time on the second business day before the first day of
the proposed special rate period; (3) an auction must have been held in the rate
period before the special rate period, and in that auction sufficient clearing
bids existed; and (4) the Fund must deposit the redemption price with the
auction agent for any shares it has decided to redeem.

     If the Fund has designated a special rate period of 14, 21, or 28 days,
then dividends generally will be paid on the same day of the week on which
dividends are paid in a seven-day rate period, but will be the second, third, or
fourth such day of the week, respectively, after the first day of the special
rate period. Thus, the dividend payment date for a special rate period of 14,
21, or 28 days generally will be the second, third, or fourth Wednesday,
respectively, after the first day of the special rate period. The dividend
payment date for a special rate period of more than 28 days will be set out in
the notice designating a special rate period. The dividend payment date will be
a business day, and the last dividend payment date for any special rate period
will be the business day immediately following the last day of the special rate

                                       27
<PAGE>   32


period. After any special rate period, the rate periods normally will be seven
days, and dividends on Municipal Preferred shares will generally be payable on
each succeeding regular dividend payment date.


VOTING RIGHTS

     In addition to voting rights described below under "Description of Capital
Structure" and in the SAI under "Investment Restrictions," holders of shares of
Municipal Preferred, voting as a separate class, are entitled to elect (1) two
trustees of the Fund at all times and (2) a majority of the trustees if at any
time dividends on shares of Municipal Preferred shall be unpaid in an amount
equal to two years' dividends thereon, and to continue to be so represented
until all dividends in arrears shall have been paid or otherwise provided for.
In all other cases, trustees shall be elected by holders of common shares and
preferred shares (including Municipal Preferred), voting together as a single
class.


     Subject to the voting rights described above and except as otherwise
specified under "Description of Capital Structure," the Fund may not, among
other things, without the approval of the holders of a "majority of the
outstanding" shares of Municipal Preferred, voting as a separate class, approve
any plan of reorganization adversely affecting shares of Municipal Preferred. In
addition, the Fund may not, without the affirmative vote of the holders of at
least a majority of the shares of Municipal Preferred outstanding at the time,
voting as a separate class: (a) authorize, create or issue additional shares of
Municipal Preferred or classes or series of preferred shares ranking prior to or
on a parity with shares of Municipal Preferred with respect to the payment of
dividends or the distribution of assets upon liquidation or (b) amend, alter or
repeal the provisions of the Declaration of Trust, the By-laws of the Fund or
the Certificate, whether by merger, consolidation or otherwise, so as to
materially affect any preference, right or power of such shares of Municipal
Preferred or the holders thereof; provided, however, that a division of a share
of Municipal Preferred shall be deemed to materially affect any such preference,
right or power only if the terms of such division adversely affect the holders
of shares of Municipal Preferred. The Fund may not, without the affirmative vote
of the holders of at least 66 2/3% of the shares of Municipal Preferred
outstanding at the time, voting as a separate class, 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. Notwithstanding the second sentence of this paragraph, the Fund may,
without the vote of the holders of shares of Municipal Preferred, authorize,
create or issue additional shares of Municipal Preferred or classes or series of
preferred shares ranking on a parity with shares of Municipal Preferred with
respect to the payment of dividends and the distribution of assets upon
liquidation if the Fund obtains written confirmation from Moody's (if Moody's is
then rating the shares of Municipal Preferred) and S&P (if S&P is then rating
the shares of Municipal Preferred) that the issuance of any such additional
shares or class or series of shares would not impair the rating then assigned by
such rating agency to shares of Municipal Preferred; provided, however, that if
Moody's or S&P is not then rating the shares of Municipal Preferred, the
aggregate liquidation preference of all preferred shares of the Fund outstanding
after any such issuance, exclusive of accumulated and unpaid dividends, may not
exceed $70,000,000.



     To the extent permitted by the 1940 Act, if any action set forth in the
preceding paragraph would adversely affect the rights of one or more series of
Municipal Preferred in a manner different from any other series of Municipal
Preferred, the Fund will not approve any such action without the affirmative
vote of the holders of at least a majority of the shares of each such affected
series outstanding at the time (each such affected series voting as a separate
class).


REDEMPTION


     Mandatory Redemption.  In the event the Fund does not timely cure a failure
to maintain (1) a discounted value of its portfolio equal to the Municipal
Preferred Basic Maintenance Amount (as defined below under "Rating Agency
Guidelines") or (2) the 1940 Act Municipal Preferred Asset Coverage (as defined
below under "Rating Agency Guidelines") in each case in accordance with the
requirements of the rating agency or agencies then rating the shares of
Municipal Preferred, shares of Municipal Preferred will be subject to mandatory
redemption on a date specified by the Board of Trustees, out of funds legally

                                       28
<PAGE>   33


available therefor in accordance with the Declaration of Trust, the Certificate
and applicable law, at the redemption price of $25,000 per share plus an amount
equal to accumulated but unpaid dividends thereon (whether or not earned or
declared) to (but not including) the date fixed for redemption. Any such
redemption will be limited to the number of shares of Municipal Preferred
necessary to restore the required discounted value or the 1940 Act Municipal
Preferred Asset Coverage, as the case may be.



     In determining the number of shares of Municipal Preferred required to be
redeemed in accordance with the foregoing, the Fund will allocate the number of
shares required to be redeemed to satisfy the Municipal Preferred Basic
Maintenance Amount or the 1940 Act Municipal Preferred Asset Coverage, as the
case may be, pro rata among shares of Municipal Preferred and other preferred
shares of the Fund, subject to redemption or retirement.


     Optional Redemption.  Shares of Municipal Preferred are redeemable, at the
option of the Fund:


          (i) in whole or in part, on the second business day preceding any
     dividend payment date for such shares, out of funds legally available
     therefor in accordance with the Declaration of Trust, the Certificate and
     applicable law, at the redemption price of $25,000 per share plus an amount
     equal to accumulated but unpaid dividends thereon (whether or not earned or
     declared) to (but not including) the date fixed for redemption; provided,
     however, that (1) shares of Municipal Preferred may not be redeemed in part
     if after such partial redemption fewer than 500 shares remain outstanding
     and (2) the notice establishing a special rate period of shares of
     Municipal Preferred, as delivered to the auction agent and filed with the
     Secretary of the Fund, may provide that such shares shall not be redeemable
     during the whole or any part of such special rate period (except as
     provided in (ii) below) or shall be redeemable during the whole or any part
     of such special rate period only upon payment of such redemption premium or
     premiums as shall be specified therein; and



          (ii) as a whole but not in part, out of funds legally available
     therefor in accordance with the Declaration of Trust, the Certificate and
     applicable law, on the first day following any dividend period included in
     a rate period of more than 364 rate period days if, on the date of
     determination of the applicable rate for such rate period, such applicable
     rate equaled or exceeded on such date of determination the Treasury Note
     Rate for such rate period, at a redemption price of $25,000 per share plus
     an amount equal to accumulated but unpaid dividends thereon (whether or not
     earned or declared) to (but not including) the date fixed for redemption.


     Notwithstanding the foregoing, if any dividends on shares of Municipal
Preferred (whether or not earned or declared) are in arrears, no shares of
Municipal Preferred shall be redeemed unless all outstanding shares of Municipal
Preferred are simultaneously redeemed, and the Fund shall not purchase or
otherwise acquire any shares of Municipal Preferred; provided, however, that the
foregoing shall not prevent the purchase or acquisition of all outstanding
shares of Municipal Preferred pursuant to the successful completion of an
otherwise lawful purchase or exchange offer made on the same terms to, and
accepted by, holders of all outstanding shares of Municipal Preferred.

LIQUIDATION

     Subject to the rights of holders of any series or class or classes of
shares ranking on a parity with shares of Municipal Preferred with respect to
the distribution of assets upon liquidation of the Fund, whether voluntary or
involuntary, the holders of shares of Municipal Preferred then outstanding will
be entitled to receive and to be paid out of the assets of the Fund available
for distribution to its shareholders, before any payment or distribution shall
be made on the common shares, an amount equal to the liquidation preference with
respect to such shares ($25,000 per share), plus an amount equal to all
dividends thereon (whether or not earned or declared) accumulated but unpaid to
(but not including) the date of final distribution in same-day funds, together
with any applicable Gross-up Payments in connection with the liquidation of the
Fund. After the payment to the holders of the shares of Municipal Preferred of
the full preferential amounts provided for as described herein, the holders of
the shares of Municipal Preferred as such shall have no right or claim to any of
the remaining assets of the Fund.

                                       29

     Neither the sale of all or substantially all the property or business of
the Fund, nor the merger or consolidation of the Fund into or with any
Massachusetts business trust or corporation nor the merger or consolidation of
any Massachusetts business trust or corporation into or with the Fund shall be a
liquidation, whether voluntary or involuntary, for the purposes of the foregoing
paragraph.

                            RATING AGENCY GUIDELINES

     The Fund is required under Moody's and S&P's guidelines to maintain assets
having in the aggregate a discounted value at least equal to the Municipal
Preferred Basic Maintenance Amount. Moody's and S&P have each 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's 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. The amount of such
assets included in the portfolio at any time may vary depending upon the rating,
diversification and other characteristics of the eligible assets included in the
portfolio. The Municipal Preferred Basic Maintenance Amount includes the sum of
(i) the aggregate liquidation preference of shares of Municipal Preferred then
outstanding and (ii) accrued and projected payment obligations of the Fund.

     The Fund is also required under rating agency guidelines to maintain, with
respect to the shares of Municipal Preferred, as of the last business day of
each month in which any shares of Municipal Preferred are outstanding, asset
coverage of at least 200% with respect to senior securities which are shares of
beneficial interest in the Fund, including shares of Municipal Preferred (or
such other asset coverage as may in the future be specified in or under the 1940
Act as the minimum asset coverage for senior securities which are shares of a
closed-end investment company as a condition of declaring dividends on its
common shares) ("1940 Act Municipal Preferred Asset Coverage"). Based on the
composition of the Fund's portfolio and market conditions as of August 31, 1999,
the 1940 Act Municipal Preferred Asset Coverage with respect to shares of
Municipal Preferred, assuming the issuance on the date hereof of all shares of
Municipal Preferred offered hereby would be computed as follows:

                                                          =                   =   277%

</TABLE>


     In the event the Fund does not timely cure a failure to maintain (1) a
discounted value of its portfolio equal to the Municipal Preferred Basic
Maintenance Amount or (2) the 1940 Act Municipal Preferred Asset Coverage, in
each case in accordance with the requirements of the rating agency or agencies
then rating the shares of Municipal Preferred, the Fund will be required to
redeem shares of Municipal Preferred as described above under "Description of
Municipal Preferred -- Redemption."

     The Fund may, but is not required to, adopt any modifications to the
guidelines that may hereafter be established by Moody's or S&P. Failure to adopt
any such modifications, however, may result in a change in the ratings described
above or a withdrawal of ratings altogether. In addition, any rating agency
providing a rating for the shares of Municipal Preferred may, at any time,
change or withdraw any such rating. The Board of Trustees may, without
shareholder approval, amend, alter or repeal any or all of the definitions and
related provisions which have been adopted by the Fund pursuant to the rating
agency guidelines in the event the Fund receives written confirmation from
Moody's or S&P, or both, as appropriate, that any such change would not impair
the ratings then assigned by Moody's and S&P to shares of Municipal Preferred.

     As described by Moody's and S&P, a preferred share rating is an assessment
of the capacity and willingness of an issuer to pay preferred share obligations.
The ratings on the Municipal Preferred are not recommendations to purchase, hold
or sell shares of Municipal Preferred, inasmuch as the ratings do not

                                       30
<PAGE>   35

comment as to market price or suitability for a particular investor. The rating
agency guidelines described above also do not address the likelihood that an
owner of shares of Municipal Preferred will be able to sell such shares in an
auction or otherwise. The ratings are based on current information furnished to
Moody's and S&P by the Fund and the 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.

     A rating agency's guidelines will apply to shares of Municipal Preferred
only so long as such rating agency is rating such shares. The Fund will pay fees
to Moody's or S&P, or both, for rating shares of Municipal Preferred.

                             MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

     The management of the Fund, including general supervision of the duties
performed by the Adviser under the Fund's investment advisory agreement, is the
responsibility of the Fund's Board of Trustees under the laws of the
Commonwealth of Massachusetts.

INVESTMENT ADVISER


     Scudder Kemper Investments, Inc., the global investment management business
of Zurich Financial Services, is one of the largest and most experienced
investment counsel firms in the world, managing assets for institutional and
corporate clients, retirement and pension plans, insurance companies, mutual
fund investors and individuals. Scudder Kemper offers a full range of investment
counsel and asset management capabilities, based on a combination of proprietary
research and disciplined, long-term investment strategies. Zurich Financial
Services Group is a financial services holding company incorporated in
Switzerland and owned 57% by Zurich Allied AG and 43% by Allied Zurich p.l.c.
The Adviser has served as investment adviser to the Fund since December 31,
1997, when the Adviser replaced Zurich Kemper Investments, Inc. and its
predecessors, which had served as the Fund's investment manager since the
inception of the Fund. As of June 30, 1999, the Adviser had more than $290
billion in assets under management. The Adviser's principal office is located at
345 Park Avenue, New York, New York 10154.


     Philip G. Condon is the lead portfolio manager and Rebecca L. Wilson is the
co-portfolio manager of the Fund. Both have been responsible for the day-to-day
management of the Fund since April 1999. Mr. Condon is a Managing Director of
the Adviser and has been the Director of the Municipal Bond Group since December
1997. He was the Head of Municipal Bond Research from May 1986 to December 1997.
He joined the Adviser in 1983. Mr. Condon received a B.A. and M.B.A. from the
University of Massachusetts, Amherst. Ms. Wilson is a Vice President and joined
the Adviser in 1986. During the past five years, she has been a co-portfolio
manager for several tax-exempt portfolios and has served as a trader for several
long-term municipal bond funds. Ms. Wilson received a B.A from the University of
Redlands, California.

     The Investment Management Agreement between the Fund and the Adviser (the
"Advisory Agreement") provides that the Adviser acts as investment adviser,
manages the Fund's investments, administers the Fund's business affairs,
furnishes offices, necessary facilities and equipment, provides clerical,
bookkeeping and administrative services, provides shareholder and information
services and permits any of its officers or employees to serve without
compensation as Trustees or officers of the Fund if duly elected to such
positions. Under the Advisory Agreement, the Fund agrees to assume and pay the
charges and expenses of its operations including, by way of example, the
compensation of the Trustees other than those affiliated with the Adviser,
charges and expenses of independent auditors, of legal counsel, of any transfer
or dividend disbursing agent, of any registrar of the Fund and of the custodian
(including fees for safekeeping of securities), costs of calculating net asset
value, all costs of acquiring and disposing of portfolio securities, interest,
if any, on obligations incurred by the Fund, costs of share certificates,
membership dues in the Investment Company Institute or any similar organization,
reports and notices to
                                       31
<PAGE>   36

shareholders, other like miscellaneous expenses and all taxes and fees to
federal, state or other governmental agencies.

     For services and facilities provided by the Adviser under the Advisory
Agreement, the Fund pays the Adviser an annualized fee, calculated and paid
monthly, in the amount of 0.60% of the average weekly net assets of the Fund.
Average weekly net assets, for purposes of determining the advisory fee, shall
mean the average weekly value of the total assets of the Fund, minus the sum of
accrued liabilities of the Fund (other than the liquidation value of any
preferred shares) and accumulated dividends on any Municipal Preferred shares.
Because the Adviser's fees are based on the average weekly net assets of the
Fund, the Adviser will benefit from an increase in the Fund's assets resulting
from the offering of shares of Municipal Preferred.

     The Advisory Agreement provides that the Adviser shall not be liable for
any error of judgment or of law, or for any loss suffered by the Fund in
connection with the matters to which the Advisory Agreement relates, except a
loss resulting from willful misfeasance, bad faith or gross negligence on the
part of the Adviser in the performance of its obligations and duties or by
reason of its reckless disregard of its obligations and duties under the
Advisory Agreement.

     The Advisory Agreement will continue in effect only if such continuance is
specifically approved at least annually by the Board of Trustees or by vote of a
majority of the outstanding common shares and all preferred shares voting as a
single class and, in either case, by a majority of the Trustees who are not
parties to the Advisory Agreement or interested persons of any such party. The
Advisory Agreement terminates automatically if it is assigned and may be
terminated without penalty by vote of a majority of the Fund's outstanding
voting securities or by either party on 60 days' written notice to the other
party.

                      CUSTODIAN, TRANSFER AGENT, DIVIDEND
                         DISBURSING AGENT AND REGISTRAR


     The Fund's securities and cash are held under a custodian agreement by
State Street Bank and Trust Company ("State Street"), whose principal place of
business is 225 Franklin Street, Boston, Massachusetts 02110. Investors
Fiduciary Trust Company ("IFTC"), whose principal place of business is 127 West
10th Street, Kansas City, Missouri 64105, serves as transfer agent, registrar
and dividend disbursing agent for the Fund's common shares. Pursuant to a
services agreement with IFTC, Kemper Service Company, an affiliate of the
Adviser, serves as Shareholder Service Agent for the Fund and, as such, performs
all of IFTC's duties as transfer agent and dividend-paying agent. The Depository
Trust Company ("DTC") will act as securities depository for the Municipal
Preferred shares. Bankers Trust Company will act as transfer agent, registrar,
dividend disbursing agent, and redemption agent for the Municipal Preferred
shares.


                                     TAXES

     The following information is meant as a general summary for U.S. taxpayers.
It is based on the advice of Dechert Price & Rhoads, counsel to the Fund, and
reflects provisions of the Internal Revenue Code (the "Code"), existing Treasury
regulations, rulings published by the IRS, and other applicable authority, as of
the date of this Prospectus. These authorities are subject to change by
legislative or administrative action. The following discussion is only a summary
of some of the important tax considerations generally applicable to investments
in the Fund. There may be other tax considerations applicable to particular
investors. In addition, income earned through an investment in the Fund may be
subject to foreign, state, or local taxes. Please see the SAI for additional
information. You should rely on your own tax adviser for advice about the tax
consequences to you of investing in the Fund.

     The Fund intends to elect and to qualify for the special tax treatment
afforded regulated investment companies ("RICs") under the Code. As long as the
Fund so qualifies, in any taxable year in which it distributes at least 90% of
the sum of its (x) net investment income (i.e., investment company taxable
income as that term is defined in the Code, without regard to the deduction for
dividends paid) and
                                       32
<PAGE>   37

(y) its net tax-exempt income (see below), the Fund will not be subject to
federal income tax on its net investment income and net capital gain (i.e., the
excess of net long-term capital gain over net short-term capital loss that it
distributes). The Fund intends to distribute all or substantially all of such
income and gain each year.

     Based in part on certain representations made by the Fund to Dechert Price
& Rhoads relating to the lack of any present intention to redeem or purchase
shares of Municipal Preferred at any time in the future, it is the opinion of
Dechert Price & Rhoads that the shares of Municipal Preferred will constitute
stock of the Fund and distributions with respect to shares of Municipal
Preferred (other than distributions in redemption of Municipal Preferred shares
that are treated as exchanges of stock under Section 302(b) of the Code) thus
will constitute dividends to the extent of the Fund's current and accumulated
earnings and profits as calculated for federal income tax purposes. This opinion
relies in part on a published ruling of the IRS stating that certain auction
rate preferred stock similar in many material respects to the Municipal
Preferred shares represents equity. It is possible, however, that the IRS might
take a contrary position asserting, for example, that the Municipal Preferred
shares constitute debt of the Fund. If this position were upheld, the discussion
of the treatment of distributions below would not apply. Instead, distributions
by the Fund to holders of shares of Municipal Preferred 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. In such event, the Fund would not be required to make payments
to such shareholders to offset the effect of paying federal income tax on fund
distributions so recharacterized as interest. Dechert Price & Rhoads has advised
the Fund that, should the IRS pursue in court the position that the shares of
Municipal Preferred should be treated as debt for federal income tax purposes,
the IRS would be unlikely to prevail.

     Each dividend distribution ordinarily will primarily constitute income
exempt from federal income tax (i.e., qualify as an "exempt-interest" dividend,
which is excludable from the shareholder's gross income). A portion of dividends
attributable to interest on certain municipal securities, however, may be a
preference item for alternative minimum tax purposes. In addition, for
corporations, alternative minimum taxable income is increased by a percentage of
the amount by which an alternative measure of income that includes interest on
all tax-exempt securities exceeds the amount otherwise determined to be
alternative minimum taxable income. Accordingly, the portion of the Fund's
dividends that would otherwise be tax-exempt to shareholders may cause certain
shareholders to be subject to the federal alternative minimum tax or may
increase the tax liability of a shareholder who is subject to such tax.
Investors should thus consider the possible effect of an investment in the Fund
on their federal alternative minimum tax liability. Furthermore, exempt-interest
dividends are included in determining what portion, if any, of a person's social
security and railroad retirement benefits will be includible in gross income
subject to federal income tax. Distributions of any taxable net investment
income (which term includes short-term capital gain) will be taxable as ordinary
income. Distributions of the Fund's net capital gain, if any, will be taxable to
shareholders as long-term capital gain, regardless of the length of time they
held their shares. Distributions, if any, in excess of the Fund's earnings and
profits will first reduce the adjusted tax basis of a holder's shares and, after
that basis has been reduced to zero, will constitute capital gain to the
shareholder (assuming the shares are held as a capital asset).

     Exempt-interest dividends attributable to interest received on certain
private activity bonds and certain industrial development bonds will not be
tax-exempt to any shareholders who are, within the meaning of Section 147(a) of
the Code, "substantial users" of the facilities financed by such obligations or
bonds or who are "related persons" of such substantial users.

     Dividends and other distributions declared by the Fund in October, November
or December of any year and payable to shareholders of record on a date in any
of those months will be deemed to have been paid by the Fund and received by the
shareholders on December 31 of that year if the distributions are paid by the
Fund during the following January. Accordingly, those distributions will be
taxed to shareholders for the year in which that December 31 falls.

                                       33
<PAGE>   38


     The Fund will inform shareholders of the source and tax status of all
distributions promptly after the close of each calendar year. The IRS has taken
the position that if a RIC has more than one class of shares, it may designate
distributions made to each class in any year as consisting of no more than that
class's proportionate share of particular types of income for that year,
including tax-exempt interest and net capital gain. A class's proportionate
share of a particular type of income for a year is determined according to the
percentage of total dividends paid by the RIC during that year that was paid to
the class. Thus, the Fund is required to allocate a portion of its net capital
gain and other taxable income to the Municipal Preferred shares. The Fund
generally will notify the auction agent of the amount of any net capital gain
and other taxable income to be included in any dividend on the shares of
Municipal Preferred prior to the auction establishing the applicable rate for
that dividend. Except for the portion of any dividend that it informs the
auction agent will be treated as net capital gain or other taxable income, the
Fund anticipates that the dividends paid on the Municipal Preferred shares will
constitute exempt-interest dividends. The amount of net capital gain and
ordinary income allocable to the Municipal Preferred shares (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 its common shares and the
Municipal Preferred shares during a taxable year, but taxable distributions
generally are not expected to be significant. The tax treatment of additional
dividends also may affect the Fund's calculation of each class's allocable share
of capital gain and other taxable income.


     Although the matter is not free from doubt, due to the absence of direct
regulatory or judicial authority, Dechert Price & Rhoads has advised the Fund
that under current law the manner in which the Fund intends to allocate items of
tax-exempt income, net capital gain, and other taxable income, if any, among the
Fund's common shares and the Municipal Preferred shares will be respected for
federal income tax purposes. It is possible that the IRS could disagree with
counsel's opinion and attempt to reallocate the Fund's net capital gain or other
taxable income. In the event of such a reallocation, some of the dividends
identified by the Fund as exempt-interest dividends to holders of shares of
Municipal Preferred may be recharacterized as additional net capital gain or
other taxable income. In the event of such recharacterization, however, the Fund
would not be required to make payments to such shareholders to offset the tax
effect of such reallocation.

     Interest on indebtedness incurred or continued by a shareholder to purchase
or carry Municipal Preferred shares is not deductible for federal income tax
purposes to the extent that interest relates to exempt-interest dividends
received from the Fund.


     If at any time when shares of the Municipal Preferred 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. Such a suspension may prevent the Fund from
distributing at least 90% of its net investment income and net tax-exempt
income, and may, therefore, jeopardize the Fund's qualification for taxation as
a RIC. Upon any failure to meet the asset coverage requirements of the 1940 Act,
the Fund, in its sole discretion, may redeem shares of the Municipal Preferred
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 for
treatment as a RIC. There can be no assurance, however, that any such action
would achieve that objective.


     Certain of the Fund's investment practices are subject to special Code
provisions that, among other things, may defer the use of certain losses of the
Fund and affect the holding period of securities held by the Fund and the
character of the gains or losses realized by the Fund. These provisions may also
require the Fund to recognize income or gain without receiving cash with which
to make distributions in the amounts necessary to satisfy the requirements for
maintaining RIC status and for avoiding income and excise taxes. The Fund will
monitor its transactions and may make certain tax elections in order to mitigate
the effect of these rules and to attempt to prevent disqualification of the Fund
as a RIC.

     If the Fund pays dividends in respect of Gross-up Payments, it will
generally designate such payments as exempt-interest dividends except to the
extent that net capital gain or other taxable income is allocated

                                       34
<PAGE>   39

thereto as described above. The federal income tax consequences of such
dividends under existing law are uncertain.

SALES OF MUNICIPAL PREFERRED

     The sale of Municipal Preferred shares (including transfers in connection
with a redemption or repurchase of Municipal Preferred shares) will be a taxable
transaction for federal income tax purposes. A selling shareholder generally
will recognize gain or loss equal to the difference between the holder's
adjusted tax basis in the Municipal Preferred shares and the amount received. If
the Municipal Preferred shares are held as capital assets, the gain or loss will
be a capital loss and will be long-term if the Municipal Preferred shares have
been held for more than one year. Any loss realized on a disposition of shares
of Municipal Preferred held for six months or less will be disallowed to the
extent of any exempt-interest dividends received with respect to those shares of
Municipal Preferred, and any such loss that is not disallowed will be treated as
a long-term, rather than a short-term, capital loss to the extent of any capital
gain distributions received with respect to those shares of Municipal Preferred.
A shareholder's holding period is suspended for any periods during which the
shareholder's risk of loss is diminished as a result of holding one or more
other positions in substantially similar or related property, or through certain
options or short sales. Any loss realized on a sale or exchange of Municipal
Preferred shares will be disallowed to the extent those Municipal Preferred
shares are replaced by other Municipal Preferred shares within a period of 61
days beginning 30 days before and ending 30 days after the date of disposition
of the original Municipal Preferred shares. In that event, the basis of the
replacement shares of Municipal Preferred will be adjusted to reflect the
disallowed loss.

BACKUP WITHHOLDING

     The Fund is required to withhold 31% of all taxable dividends, capital gain
dividends and repurchase proceeds payable to any individuals and certain other
non-corporate shareholders who do not provide the Fund with a correct taxpayer
identification number. Withholding at that rate from taxable dividends and
capital gain distributions is also required for such shareholders who otherwise
are subject to backup withholding.
                            ------------------------

     The foregoing briefly summarizes some of the important federal income tax
consequences of investing in shares of Municipal Preferred, reflects the federal
tax law, as of the date of this Prospectus, and does not address special tax
rules applicable to certain types of investors, such as corporate and foreign
investors. Other federal, state or local tax considerations may apply to a
particular investor, including state alternative minimum tax. Investors should
consult their tax advisers.

                        DESCRIPTION OF CAPITAL STRUCTURE


     The Fund is an unincorporated business trust established under the laws of
the Commonwealth of Massachusetts by the Declaration of Trust dated February 27,
1989. The Declaration of Trust provides that the Trustees of the Fund may
authorize separate classes of shares of beneficial interest. The Trustees have
authorized an unlimited number of shares of beneficial interest, par value $0.01
per share, all of which were initially classified as common shares. The
Declaration of Trust also authorizes the issuance of an unlimited number of
shares of beneficial interest with preference rights, including preferred
shares, having a par value of $0.01 per share, in one or more series, with
rights as determined by the Board of Trustees, by action of the Board of
Trustees without the approval of the shareholders. For a description of the
Municipal Preferred shares, see "Description of Municipal Preferred." The
following table shows the amount of (i) shares authorized, (ii) shares held by
the Fund


                                       35

for its own account and (iii) shares outstanding, for each class of authorized
securities of the Fund as of August 31, 1999.

     The common shares outstanding are fully paid and nonassessable by the Fund.
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 common shares are not redeemable. Upon
liquidation of the Fund, after paying or adequately providing for the payment of
all liabilities of the Fund and the liquidation preference with respect to any
outstanding preferred shares, and upon receipt of such releases, indemnities and
refunding agreements as they deem necessary for their protection, the Trustees
may distribute the remaining assets of the Fund among the holders of the common
shares. Under the rules of the NYSE applicable to listed companies, the Fund
will be required to hold an annual meeting of shareholders in each year. If the
Fund is converted to an open-end investment company or if for any other reason
common shares are no longer listed on the NYSE (or any other national securities
exchange the rules of which require annual meetings of shareholders), the Fund
does not intend to hold annual meetings of shareholders.


     Under Massachusetts law, shareholders could, under certain circumstances,
be held personally liable for the obligations of the Fund. However, the
Declaration of Trust disclaims shareholder liability for acts or obligations of
the Fund and requires that notice of such disclaimer be given in each agreement,
obligation or instrument entered into or executed by the Fund or the Trustees.
The Declaration of Trust provides for indemnification out of Fund property for
all loss and expense of any shareholder held personally liable for the
obligations of the Fund. Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is limited to circumstances in which
the Fund would be unable to meet its obligations.


     Holders of common shares are entitled to one vote for each share held and
will vote with the holders of any outstanding Municipal Preferred shares or
other preferred shares on each matter submitted to a vote of holders of common
shares, except as described under "Description of Municipal Preferred -- Voting
Rights."

     Shareholders are entitled to one vote for each share held. The common
shares, Municipal Preferred shares and any other preferred shares do not have
cumulative voting rights, which means that the holders of more than 50% of the
shares of common shares, Municipal Preferred shares 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 shares of common shares, Municipal Preferred shares and any other
preferred shares will not be able to elect any of such Trustees.


     The issuance of Municipal Preferred will create leverage which will affect
the amount of income available for distribution on the common shares and the net
asset value of the common shares. The applicable dividend rates on the Municipal
Preferred could exceed both the current yield on the Fund's portfolio
investments and the yield received on investments made with the proceeds of the
issuance of the offering of the shares of Municipal Preferred. Therefore, the
offering could result in a decline in the Fund's net asset value and a reduction
of net investment income available for distribution on common shares.


     So long as any Municipal Preferred shares 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 at the time of such
declaration, (1) all accrued dividends on preferred shares or accrued interest
on

                                       36
<PAGE>   41

borrowings has been paid and (2) the value of the Fund's total assets
(determined after deducting the amount of such dividend or other distribution),
less all liabilities and indebtedness of the Fund not represented by senior
securities, is at least 300% of the aggregate amount of such securities
representing indebtedness and at least 200% of the aggregate amount of
securities representing indebtedness plus the aggregate liquidation value of the
outstanding preferred shares (expected to equal the aggregate original purchase
price of the outstanding preferred shares plus redemption premium, if any,
together with any accrued and unpaid dividends thereon, whether or not earned or
declared and on a cumulative basis). In addition to the requirements of the 1940
Act, the Fund is required to comply with other asset coverage requirements as a
condition of the Fund obtaining a rating of the preferred shares from a rating
agency. These requirements include an asset coverage test more stringent than
under the 1940 Act.

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

     The Fund has no present intention of offering additional common shares
except for the issuance of common shares under the Fund's dividend reinvestment
plan, which allows holders of common shares to reinvest dividends and capital
gain distributions from the Fund, if any, in additional common shares of the
Fund. The dividend reinvestment plan is not available to holders of Municipal
Preferred. Other offerings of its common shares, if made, will require approval
of the Fund's Board of Trustees. Any additional offering will not be sold at a
price per common share below the then-current net asset value (exclusive of
underwriting discounts and commissions) except in connection with an offering to
existing holders of common shares or with the consent of a majority of the
Fund's outstanding common shares. In addition, the Fund expects that it would
commence a continuous offering of its shares in the event it converted to an
open-end investment company. See "-- Conversion to Open-End Fund."


     The Declaration of Trust further provides that obligations of the Fund are
not binding upon Trustees individually but only upon the property of the Fund
and that the Trustees will not be liable for errors of judgment or mistakes of
fact or law, but nothing in the Declaration of Trust protects a Trustee against
any liability to which he/ she would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of his/ her office.


     The common shares have traded on the NYSE since March 22, 1989. The
following table shows the ranges of the Fund's net asset value per common share

     As of August 31, 1999, the net asset value per share of common shares was
$11.64, and the closing price per share of common shares on the NYSE was
$11.375.

PREFERRED SHARES

     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 Municipal Preferred shares or any other
preferred shares that might be issued. It is anticipated that the net asset
value per share of the Municipal Preferred shares will equal its original
purchase price per share plus accumulated dividends per share.

CONVERSION TO OPEN-END FUND

     The Trustees may at any time propose conversion of the Fund to an open-end
management investment company depending upon their judgment as to the
advisability of such action in light of circumstances then prevailing. In
considering whether to submit an open-ending proposal to shareholders, the
Trustees might consider, among other factors, the differences in operating
expenses between open-end and closed-end funds (due to the expenses of
continuously selling shares and of standing ready to effect redemptions), the
potentially adverse tax consequences to non-redeeming shareholders once a fund
is open-ended, and the impact of open-ending on portfolio management policies.
Such a conversion would require the approval of both a majority of the Fund's
outstanding common shares and Municipal Preferred shares voting together as a
single class and a majority of the outstanding Municipal Preferred shares voting
as a separate class on such conversion. Conversion of the Fund to an open-end
investment company would require the redemption of all outstanding preferred
shares, including the Municipal Preferred shares, which would eliminate the
leveraged capital structure of the Fund with respect to the common shares. A
delay in conversion could result following shareholder approval due to the
Fund's inability to redeem the preferred shares. Shareholders of an open-end
investment company may require the company to redeem their shares at any time
(except in certain circumstances as authorized by or under the 1940 Act) at
their next computed net asset value less any redemption charge as might be in
effect at the time of redemption. If the Fund is converted to an open-end
management investment company, it could be required to liquidate portfolio
securities to meet requests for redemption, and its shares would no longer be
listed on the NYSE. If the Fund were to experience significant redemptions as an
open-end fund, the decrease in total assets could result in a higher expense
ratio and inefficiencies in portfolio management. In this regard, the Fund could
reserve the right to effect redemptions in-kind with portfolio securities, which
would subject redeeming shareholders to transaction costs in liquidating those
securities.

REPURCHASE OF COMMON SHARES

     Shares of closed-end management investment companies frequently trade at a
discount from net asset value but in some cases trade at a premium. In
recognition of the possibility that the Fund's shares might similarly trade at a
discount, the Fund may from time to time take action to attempt to reduce or
eliminate a market value discount from net asset value by repurchasing its
shares in the open market or by tendering for its own shares at net asset value.
The Board of Trustees, in consultation with the Adviser, reviews on a quarterly
basis the possibility of open market repurchases and/or tender offers for Fund
shares. There are no assurances that the Board of Trustees will, in fact, decide
to undertake either of these actions or, if undertaken, that such actions will
result in the Fund's shares trading at a price which is equal to or approximates
their net asset value. In addition, the Board of Trustees will not necessarily
announce when it has given consideration to these matters. Notwithstanding the
foregoing, so long as any shares of Municipal Preferred are outstanding, the
Fund may not purchase, redeem or otherwise acquire any common shares unless (1)
all accumulated dividends on the shares of Municipal Preferred have been paid or
set aside for payment through the date of such purchase, redemption or other
acquisition and (2) at the time of such purchase, redemption or acquisition the
Municipal Preferred Basic Maintenance Amount and the 1940 Act Municipal
Preferred Asset Coverage (determined after deducting the acquisition price of
the common shares) are met.


     Subject to the Fund's investment policies and restrictions with respect to
borrowings, the Fund may incur debt to finance repurchases and/or tenders. See
"Investment Objective, Policies and Risks" in this Prospectus and "Investment
Restrictions" in the SAI. Interest on any such borrowings will reduce the Fund's
net investment income.


     Although the Board of Trustees believes that share repurchases and tenders
generally would have a favorable effect on the market price of the Fund's
shares, it should be recognized that the acquisition of shares by the Fund will
decrease the total assets of the Fund and, therefore, have the effect of
increasing the Fund's expense ratio. In addition, any purchase by the Fund of
its common shares at a time when the Municipal Preferred shares are outstanding
will increase the leverage applicable to the outstanding common shares then
remaining. Such leverage would be further increased if the Fund were to borrow
                                       38
<PAGE>   43

money to finance repurchases. Under the Fund's Certificate, the Fund may not
borrow more than 5% of its total assets for temporary purposes, including share
repurchases, without the prior written permission of Moody's and S&P. Such
leverage may exaggerate changes in the net asset value and the yield on the
Fund's portfolio. Repurchases of common shares may result in the Fund being
required to redeem Municipal Preferred shares to satisfy asset coverage
requirements. Because of the nature of the Fund's investment objective and
policies and the Fund's portfolio, the Adviser does not anticipate that
repurchases and tenders should have a materially adverse effect on the Fund's
investment performance and does not anticipate any material difficulty in
disposing of portfolio securities in order to consummate share repurchases and
tenders.

     The portfolio turnover rate of the Fund may or may not be affected by the
Fund's repurchases of shares pursuant to a tender offer.

                                  UNDERWRITING


     Subject to the terms and conditions of the Underwriting Agreement between
Salomon Smith Barney Inc. (the "underwriter") and the Fund (the "Underwriting
Agreement") dated the date hereof, the underwriter has agreed to purchase, and
the Fund has agreed to sell, 2,800 shares of Series T Municipal Preferred
offered hereby.



     The Underwriting Agreement provides that the obligations of the underwriter
to purchase the shares included in this offering are subject to the approval of
certain legal matters by counsel and to certain other conditions. The
underwriter is obligated to purchase all of the shares of Municipal Preferred
offered hereby if it purchases any of the shares. In the Underwriting Agreement,
the Fund and the Adviser have agreed to indemnify the underwriter against
certain liabilities, including liabilities arising under the Securities Act of
1933, as amended, or to contribute payments the underwriter may be required to
make for any of those liabilities.



     The Fund has been advised by the underwriter that it proposes initially to
offer some of the shares of Municipal Preferred directly to the public at the
public offering price set forth on the cover page of this Prospectus and some of
the shares to selected dealers at the public offering price less a concession
not in excess of $     per share. The underwriting commission the Fund will pay
of $     per share is equal to      % of the initial offering price. The
underwriter may allow, and such dealers may reallow, a concession not in excess
of $     per share on sales to certain other dealers. After the initial public
offering, the underwriter may change the public offering price and the
concession. Investors must pay for any shares of Municipal Preferred purchased
in the initial public offering on or before             , 1999.



     The Fund anticipates that the underwriter may from time to time act as a
broker or dealer in connection with the execution of its portfolio transactions
after it has ceased to be an underwriter. The Fund anticipates that the
underwriter or one of its affiliates may from time to time act in auctions as a
broker-dealer and will receive fees as described under "The Auction" and in the
SAI. The underwriter is an active underwriter of, and dealer in, securities and
acts as a market maker in a number of such securities, and therefore can be
expected to engage in portfolio transactions with the Fund.


     The principal business address of Salomon Smith Barney Inc. is 388
Greenwich Street, New York, New York 10013.

                                 LEGAL MATTERS


     Vedder, Price, Kaufmann & Kammholz, Chicago, Illinois, serves as counsel to
the Fund and to the non-interested Trustees. Dechert Price & Rhoads, Washington,
DC, which is serving as special counsel to the Fund with respect to the offering
of Municipal Preferred shares, will pass on the legality of the shares offered
hereby. Certain legal matters will be passed on for the underwriter by Simpson
Thacher & Bartlett, New York, New York. Simpson Thacher & Bartlett will rely as
to certain matters under Massachusetts law on the opinion of Dechert Price &
Rhoads.

                              GENERAL INFORMATION

     The Fund is a closed-end, non-diversified management investment company
registered under the Investment Company Act of 1940, as amended (the "1940
Act"). The Fund's investment adviser is Scudder Kemper Investments, Inc. (the
"Adviser"). The Fund's investment objective is to provide a high level of
current income exempt from federal income tax. The Fund invests at least 50% of
its total assets in investment grade Municipal Securities or unrated Municipal
Securities of comparable quality and may invest up to 50% of its total assets in
high-yield Municipal Securities that are rated below investment grade or unrated
Municipal Securities of comparable quality. The Fund will not purchase Municipal
Securities rated lower than B- by S&P or B by Moody's or unrated Municipal
Securities of comparable quality.


     Capitalized terms used in this SAI are defined in the glossary beginning on
page 52.


                    ADDITIONAL INFORMATION ABOUT INVESTMENTS
                           AND INVESTMENT TECHNIQUES


     Some of the different types of securities in which the Fund may invest,
subject to its investment objective, policies and restrictions, are described in
the Prospectus, dated September 20, 1999 (the "Prospectus"), under "Investment
Objective, Policies and Risks." Additional information concerning certain of the
Fund's investments and investment techniques is set forth below.


     MUNICIPAL SECURITIES.  Municipal Securities are issued to obtain funds for
various public and private purposes. Municipal Securities include long-term
obligations, which are often called municipal bonds, as well as tax-exempt
commercial paper, project notes and municipal notes such as tax, revenue and
bond anticipation notes of short maturity, generally less than three years.
Market rates of interest available with respect to Municipal Securities may be
lower than those available with respect to taxable securities, although such
differences may be partially or wholly offset by the effects of federal income
tax on income derived from taxable securities. While most municipal bonds pay a
fixed rate of interest semi-annually in cash, some bonds pay no periodic cash
interest but instead make a single payment at maturity representing both
principal and interest. Municipal Securities may be issued or subsequently
offered with interest coupons materially greater or less than those then
prevailing, with price adjustments reflecting such deviation.

     In general, there are three categories of Municipal Securities the interest
on which is exempt from federal income tax and is not a tax preference item for
purposes of the federal alternative minimum tax ("AMT") ("Preference Items"):
(i) certain "public purpose" obligations (whenever issued), which include
obligations issued directly by state and local governments or their agencies to
fulfill essential governmental functions; (ii) certain obligations issued before
August 8, 1986 for the benefit of non-governmental persons or entities; and
(iii) certain "private activity bonds" issued after August 7, 1986, which
include "qualified Section 501(c)(3) bonds" or refundings of certain obligations
included in the second category. Interest on obligations in the last category is
exempt from federal income tax but is treated as a Preference Item that could
subject the recipient to, or increase the recipient's liability for, the AMT.
For corporate shareholders, the Fund's distributions derived from interest on
all Municipal Securities (whenever issued) is included in "adjusted current
earnings" for purposes of the AMT (to the extent not already included in
alternative minimum taxable income as income attributable to private activity
bonds). In assessing the federal income tax treatment of interest on any such
obligation, the Fund will rely on an opinion of the issuer's counsel (when
available) obtained by the issuer or other reliable authority and will not
undertake any independent verification thereof.

     The two principal classifications of municipal bonds are "general
obligation" and "revenue" bonds. Issuers of general obligation bonds include
states, counties, cities, towns and regional districts. The proceeds of these
obligations are used to fund a wide range of public projects including the
construction or improvement of schools, highways and roads, water and sewer
systems and a variety of other public

                                        2
<PAGE>   50

purposes. The basic security of general obligation bonds is the issuer's pledge
of its faith, credit, and taxing power for the payment of principal and
interest. The taxes that can be levied for the payment of debt service may be
limited or unlimited as to rate and amount.

     Revenue bonds are generally secured by the net revenues derived from a
particular facility or group of facilities or, in some cases, from the proceeds
of a special excise or other specific revenue source. Revenue bonds have been
issued to fund a wide variety of capital projects including: electric, gas,
water, sewer and solid waste disposal systems; highways, bridges and tunnels;
port, airport and parking facilities; transportation systems; housing
facilities, colleges and universities and hospitals. Although the principal
security behind these bonds varies widely, many provide additional security in
the form of a debt service reserve fund whose monies may be used to make
principal and interest payments on the issuer's obligations. Housing finance
authorities have a wide range of security including partially or fully insured,
rent subsidized and/or collateralized mortgages, and/or the net revenues from
housing or other public projects. In addition to a debt service reserve fund,
some authorities provide further security in the form of a state's ability
(without legal obligation) to make up deficiencies in the debt service reserve
fund. Lease rental revenue bonds issued by a state or local authority for
capital projects are normally secured by annual lease rental payments from the
state or locality to the authority sufficient to cover debt service on the
authority's obligations. Such payments are usually subject to annual
appropriations by the state or locality. Industrial development and pollution
control bonds, although normally issued by municipal authorities, are in most
cases revenue bonds and are generally not secured by the taxing power of the
municipality, but are usually secured by the revenues derived by the authority
from payments of the industrial user or users. The Fund may on occasion acquire
revenue bonds which carry warrants or similar rights covering equity securities.
Such warrants or rights may be held indefinitely, but if exercised, the Fund
anticipates that it would, under normal circumstances, dispose of any equity
securities so acquired within a reasonable period of time.

     The obligations of any person or entity to pay the principal of and
interest on a Municipal Security are subject to the provisions of bankruptcy,
insolvency and other laws affecting the rights and remedies of creditors, such
as the Federal Bankruptcy Act, and laws, if any, which may be enacted by
Congress or state legislatures extending the time for payment of principal or
interest, or both, or imposing other constraints upon enforcement of such
obligations. There is also the possibility that as a result of litigation or
other conditions the power or ability of any person or entity to pay when due
principal of and interest on a Municipal Security may be materially affected.
There have been recent instances of defaults and bankruptcies involving
Municipal Securities which were not foreseen by the financial and investment
communities. The Fund will take whatever action it considers appropriate in the
event of anticipated financial difficulties, default or bankruptcy of either the
issuer of any Municipal Security or of the underlying source of funds for debt
service. Such action may include retaining the services of various persons or
firms (including affiliates of the Adviser) to evaluate or protect any real
estate, facilities or other assets securing any such obligation or acquired by
the Fund as a result of any such event, and the Fund may also manage (or engage
other persons to manage) or otherwise deal with any real estate, facilities or
other assets so acquired. The Fund anticipates that real estate consulting and
management services may be required with respect to properties securing various
Municipal Securities in its portfolio or subsequently acquired by the Fund. The
Fund will incur additional expenditures in taking protective action with respect
to portfolio obligations in default and assets securing such obligations. To
enforce its rights in the event of a default in the payment of interest or
repayment of principal, or both, the Fund may take possession of and manage the
assets or have a receiver appointed to collect and disburse pledged revenues
securing the issuer's obligations on such securities, which may increase the
operating expenses and adversely affect the net asset value of the Fund. Any
income derived from the ownership of operation of such assets may not be
tax-exempt. In addition, the Fund's intention to qualify as a "regulated
investment company" ("RIC") under the Code may limit the extent to which the
Fund may exercise its rights by taking possession of such assets, because as a
RIC the Fund is subject to certain limitations on its investments and on the
nature of its income. See "Taxes".

                                        3

     The yields on Municipal Securities are dependent on a variety of factors,
including purposes of issue and source of funds for repayment, general money
market conditions, general conditions of the municipal bond market, size of a
particular offering, maturity of the obligation and rating of the issue. The
ratings of Moody's and S&P represent their opinions as to the quality of the
Municipal Securities which they undertake to rate. It should be emphasized,
however, that ratings are based on judgment and are not absolute standards of
quality. Consequently, Municipal Securities with the same maturity, coupon and
rating may have different yields while obligations of the same maturity and
coupon with different ratings may have the same yield. In addition, the market
price of Municipal Securities will normally fluctuate with changes in interest
rates, and therefore the net asset value of the Fund will be affected by such
changes.

     Hospital bond ratings are often based on feasibility studies which contain
projections of expenses, revenues and occupancy levels. Among the influences
affecting a hospital's gross receipts and net income available to service its
debt are demand for hospital services, the ability of the hospital to provide
the services required, management capabilities, economic developments in the
service area, efforts by insurers and government agencies to limit rates and
expenses, confidence in the hospital, service area economic developments,
competition, availability and expense of malpractice insurance, Medicaid and
Medicare funding and possible federal legislation limiting the rates of increase
of hospital charges.

     Electric utilities face problems in financing large construction programs
in an inflationary period, cost increases and delay occasioned by safety and
environmental considerations (particularly with respect to nuclear facilities),
difficulty in obtaining fuel at reasonable prices and in achieving timely and
adequate rate relief from regulatory commissions, effects of energy conservation
and limitations on the capacity of the capital market to absorb utility debt.

     Bonds to finance life care facilities are normally secured only by the
revenues of each facility and not by state or local government tax payments,
they are subject to a wide variety of risks. Primarily, the projects must
maintain adequate occupancy levels to be able to provide revenues sufficient to
meet debt service payments. Moreover, since a portion of housing, medical care
and other services may be financed by an initial deposit, it is important that
the facility maintain adequate financial reserves to secure estimated actuarial
liabilities. The ability of management to accurately forecast inflationary cost
pressures is an important factor in this process. The facilities may also be
affected adversely by regulatory cost restrictions applied to health care
delivery in general, particularly state regulations or changes in Medicare and
Medicaid payments or qualifications, or restrictions imposed by medical
insurance companies. They may also face competition from alternative health care
or conventional housing facilities in the private or public sector.

     MUNICIPAL LEASES.  The Fund may invest in municipal leases and
participations therein, which arrangements frequently involve special risks.
Municipal leases are obligations in the form of a lease or installment purchase
arrangement which is issued by state or local governments to acquire equipment
and facilities. Interest income from such obligations is generally exempt from
local and state taxes in the state of issuance. "Participations" in such leases
are undivided interests in a portion of the total obligation. Participations
entitle their holders to receive a pro rata share of all payments under the
lease. The obligation of the issuer to meet its obligations under such leases is
often subject to the appropriation by the appropriate legislative body, on an
annual or other basis, of funds for the payment of the obligations. Investments
in municipal leases are thus subject to the risk that the legislative body will
not make the necessary appropriation and the issuer will not otherwise be
willing or able to meet its obligation. Certain municipal lease obligations are
illiquid.

     WHEN-ISSUED SECURITIES.  New issues of Municipal Securities are sometimes
offered on a "when-issued" basis, that is, delivery and payment for the
securities normally take place within a specified number of days after the date
of the Fund's commitment and are subject to certain conditions such as the
issuance of satisfactory legal opinions. The Fund may also purchase securities
on a when-issued basis pursuant to refunding contracts in connection with the
refinancing of an issuer's outstanding indebtedness. Refunding contracts
generally require the issuer to sell and the Fund to buy such securities on a
settlement

                                        4
<PAGE>   52

date that could be several months or several years in the future. The Fund may
also purchase instruments that give the Fund the option to purchase a Municipal
Security when and if issued.

     The Fund will make commitments to purchase when-issued securities only with
the intention of actually acquiring the securities, but may sell such securities
before the settlement date if it is deemed advisable as a matter of investment
strategy. The payment obligation and the interest rate that will be received on
the securities are fixed at the time the Fund enters into the purchase
commitment. When the Fund commits to purchase a security on a when-issued basis
it records the transaction and reflects the value of the security in determining
its net asset value. Securities purchased on a when-issued basis and the
securities held by the Fund are subject to changes in value based upon the
perception of the creditworthiness of the issuer and changes in the level of
interest rates (i.e. appreciation when interest rates decline and depreciation
when interest rates rise). Therefore, to the extent that the Fund remains
substantially fully invested at the same time that it has purchased securities
on a when-issued basis, there will be greater fluctuations in the Fund's net
asset value than if it set aside cash to pay for when-issued securities.

     REDEMPTION, DEMAND AND PUT FEATURES AND PUT OPTIONS.  Issuers of Municipal
Securities reserve the right to call (redeem) the bond. If an issuer redeems
securities held by the Fund during a time of declining interest rates, the Fund
may not be able to reinvest the proceeds in securities providing the same
investment return as the securities redeemed. Also, some bonds may have "put" or
"demand" features that allow early redemption by the bondholder. Longer term
fixed-rate bonds may give the holder a right to request redemption at certain
times (often annually after the lapse of an intermediate term). These bonds are
more defensive than conventional long term bonds because they may protect to
some degree against a rise in interest rates.

     LIQUIDITY AND PROTECTIVE PUT OPTIONS.  The Fund may also enter into a
separate agreement with the seller of a security or some other person granting
the Fund the right to put the security to the seller thereof or the other person
at an agreed upon price. Such agreements are subject to the risk of default by
the other party, although the Fund intends to limit this type of transaction to
institutions (such as banks or securities dealers) which the Adviser believes
present minimal credit risks. The Fund would engage in this type of transaction
to facilitate portfolio liquidity or (if the seller so agrees) to hedge against
rising interest rates. There is no assurance that this kind of put option will
be available to the Fund or that selling institutions will be willing to permit
the Fund to exercise a put to hedge against rising interest rates. The Fund does
not expect to assign any value to any separate put option which may be acquired
to facilitate portfolio liquidity, inasmuch as the value (if any) of the put
will be reflected in the value assigned to the associated security; any put
acquired for hedging purposes would be valued in good faith under methods or
procedures established by the Trustees of the Fund after consideration of all
relevant factors, including its expiration date, the price volatility of the
associated security, the difference between the market price of the associated
security and the exercise price of the put, the creditworthiness of the issuer
of the put and the market prices of comparable put options. Interest income
generated by certain bonds having put or demand features may be taxable.

     ILLIQUID OBLIGATIONS.  At times, a substantial portion of the Fund's assets
may be invested in securities as to which the Fund, by itself or together with
other accounts managed by the Adviser and its affiliates, holds a major portion
or all of such securities. Under adverse market or economic conditions or in the
event of adverse changes in the financial condition of the issuer, the Fund
could find it more difficult to sell such securities when the Adviser believes
it advisable to do so or may be able to sell such securities only at prices
lower than if such securities were more widely held. Under such circumstances,
it may also be more difficult to determine the fair value of such securities for
purposes of computing the Fund's net asset value.

     The secondary market for some Municipal Securities issued within a state
(including issues which are privately placed with the Fund) is less liquid than
that for taxable debt obligations or other more widely traded Municipal
Securities. No established resale market exists for certain of the Municipal
Securities in which the Fund may invest. The market for obligations rated below
investment grade is also likely to be

                                        5
<PAGE>   53

less liquid than the market for higher rated obligations. As a result, the Fund
may be unable to dispose of these Municipal Securities at times when it would
otherwise wish to do so at the prices at which they are valued.

     ZERO-COUPON BONDS.  The Fund may invest in zero-coupon bonds, which are
issued at a significant discount from face value and pay interest only at
maturity rather than at intervals during the life of the security. The values of
zero-coupon bonds are subject to greater fluctuation in response to changes in
market interest rates than bonds that pay interest currently.

     INVERSE FLOATERS.  The Fund may invest in inverse floaters, also called
residual interest bonds, whose interest rates bear an inverse relationship to
the interest rate on another security or the value of an index. Because changes
in the interest rate on the other security or index inversely affect the
residual interest paid on the inverse floater, the value of an inverse floater
is generally more volatile than that of a fixed rate bond. Inverse floaters tend
to underperform the market for fixed rate bonds in a rising interest rate
environment, but tend to outperform the market for fixed rate bonds when
interest rates decline. Although generally volatile, inverse floaters typically
offer the potential for yields exceeding the yields available on fixed rate
bonds with comparable credit quality, coupon, call provisions, and maturity.

     FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS.  A change in the level
of interest rates may affect the value of the securities held by the Fund (or of
securities that the Fund expects to purchase). All futures contracts entered
into by the Fund are traded on exchanges or boards of trade that are licensed
and regulated by the Commodity Futures Trading Commission ("CFTC") and must be
executed through a futures commission merchant or brokerage firm which is a
member of the relevant exchange. The Fund will be required, in connection with
transactions in futures contracts, to make margin deposits, which will be held
by the Fund's custodian for the benefit of the futures commission merchant
through whom the Fund engages in such futures and options transactions.

     Some futures contracts and options thereon may become illiquid under
adverse market conditions. In addition, during periods of market volatility, a
commodity exchange may suspend or limit transactions in an exchange-traded
instrument, which may make the instrument temporarily illiquid and difficult to
price.

     Commodity exchanges may also establish daily limits on the amount that the
price of a futures contract or futures option can vary from the previous day's
settlement price. Once the daily limit is reached, no trades may be made that
day at a price beyond the limit. This may prevent the Fund from closing out
positions and limiting its losses.

     The Fund will engage in futures and related options transactions for bona
fide hedging purposes or non-hedging purposes as defined in or permitted by CFTC
regulations. The Fund will determine that the price fluctuations in the futures
contracts used for hedging purposes are substantially related to price
fluctuations in securities held by the Fund or which it expects to purchase. The
Fund will engage in transactions in futures and related options contracts only
to the extent such transactions are consistent with the requirements of the Code
for maintaining its qualification as a RIC for federal income tax purposes.

                            INVESTMENT RESTRICTIONS

     The following investment restrictions of the Fund are designated as
fundamental policies and as such cannot be changed without the approval of the
holders of a majority of the Fund's outstanding voting securities, which as used
in the Prospectus and this SAI means the lesser of (a) 67% or more of the shares
of the Fund present or represented by proxy at a meeting if the holders of more
than 50% of the outstanding shares are present or represented at the meeting or
(b) more than 50% of outstanding shares of the Fund. Except with respect to
borrowings, all percentage limitations set forth below apply immediately after a
purchase or initial investment and no subsequent change in any applicable
percentage resulting from market fluctuations require elimination of any
security from the portfolio. Subsequent to the issuance of Municipal Preferred,
the following investment restrictions may not be changed without the approval of
a majority of the outstanding Common Shares and of Municipal Preferred shares
(and any other Preferred Shares that may be issued in the future), voting
together as a class, and the approval of a majority of the outstanding shares of
Municipal Preferred (and any other Preferred Shares that may be issued in the
future), voting separately as a class. All other investment policies and
practices described in the Prospectus or in this SAI are not fundamental and may
be changed without shareholder approval. The Fund will not:


           (1) Issue senior securities, as defined in the 1940 Act, other than
     (i) preferred shares which immediately after issuance will have asset
     coverage of at least 200%, (ii) the borrowings described under subparagraph
     3 below or (iii) transactions involving futures contracts or the writing of
     options within the limits described in the registration statement;



           (2) Make short sales of securities or purchase any securities on
     margin (except for such short term credits as are necessary for the
     clearance of transactions), or write or purchase put or call options,
     except to the extent that the purchase of a stand-by commitment may be
     considered the purchase of a put, and except for transactions involving
     options within the limits described in the registration statement;


           (3) Borrow money, except for temporary or emergency purposes or for
     repurchase of its shares, and then only in an amount not exceeding
     one-third of the value of the Fund's total assets including the amount
     borrowed; however, the Fund will not purchase any securities for its
     portfolio at any time when the borrowings exceed 5% of its total assets
     (taken at value);

           (4) Underwrite any issue of securities, except to the extent that the
     purchase of municipal securities in accordance with its investment
     objective, policies and limitations may be deemed to be an underwriting;

           (5) Invest more than 25% of its total assets in securities of issuers
     in any one industry; provided, however, that such limitation shall not be
     applicable to municipal securities other than those municipal securities
     backed only by the assets and revenues of non-governmental issuers, nor
     shall it apply to municipal securities issued or guaranteed by the U.S.
     Government, its agencies or instrumentalities;

           (6) Purchase or sell real estate, but this shall not prevent the Fund
     from investing in municipal securities secured by real estate or interests
     therein;


           (7) Purchase or sell commodities or commodities contracts, except for
     transactions involving futures contracts or options on such contracts
     within the limits described in the registration statement;


           (8) Make loans, other than by entering into repurchase agreements and
     through the purchase of municipal securities or temporary investments in
     accordance with its investment objective, policies and limitations;


           (9) Invest in securities other than municipal securities and
     temporary investments as those terms are defined in the registration
     statement;


                                        7
<PAGE>   55

          (10) Invest more than 5% of its total assets in securities of any one
     issuer, except that this limitation shall not apply to securities of the
     United States government, its agencies and instrumentalities and except
     that with respect to 50% of the Fund's total assets the Fund may invest up
     to 25% of its total assets in securities of any one issuer; or

          (11) Invest more than 10% of its total assets in repurchase agreements
     maturing in more than seven days.

     For purposes of applying the limitation set forth in subparagraph (10)
above, an issuer shall be deemed a separate issuer when its assets and revenues
are separate from other governmental entities and its securities are backed only
by its assets and revenues. Similarly, in the case of a non-governmental issuer,
such as an industrial corporation or a privately owned or operated hospital, if
the security is backed only by the assets and revenues of the non-governmental
issuer then such non-governmental issuer would be deemed to be the sole issuer.
Where a security is also backed by the enforceable obligations of a superior
governmental entity, it shall be included in the computation of securities owned
that are issued by such superior governmental entity. If, however, a security is
guaranteed by a governmental entity or some other entity, as in the case of a
bank guarantee or letter of credit, such a guarantee or letter of credit would
be considered a separate security and would be treated as an issue of such
government, other entity or bank.

     Whenever an investment policy or investment restriction set forth in the
Prospectus or this SAI states a maximum percentage of assets that may be
invested in any security or other asset or describes a policy regarding quality
standards, such percentage limitation or standard shall be determined
immediately after and as a result of the Fund's acquisition of such security or
asset. Accordingly, any later increase or decrease resulting from a change in
values, assets or other circumstances will not compel the Fund to dispose of
such security or other asset. Notwithstanding the foregoing, the Fund must
always be in compliance with the borrowing policies set forth above.

investment management organizations in the world, managing more than $290
billion in assets, as of June 30, 1999, for institutional and corporate clients,

     The Advisory Agreement provides that the Adviser will provide portfolio
management services, place portfolio transactions in accordance with policies
expressed in the Fund's registration statement, pay the Fund's office rent, and
render significant administrative services on behalf of the Fund (not otherwise

filings with the SEC and other regulatory and self-regulatory organizations,
including but not limited to, preliminary and definitive proxy materials,

monitoring the registration of shares of the Fund under applicable federal and
state securities laws; maintaining or causing to be maintained for the Fund all

establishing accounting policies of the Fund; assisting in the resolution of
accounting issues that may arise with respect to the Fund's operations and
consulting with the Fund's independent accountants, legal counsel and other
agents as necessary in connection therewith; establishing and monitoring the

payment of bills that have been approved by an authorized person; assisting the
Fund in determining the amount of dividends and distributions available to be
paid by the Fund to its shareholders, preparing and arranging for the printing
of dividend notices to shareholders, and providing the transfer and dividend
paying agent, the custodian, and the accounting agent with such information as
is required for such parties to effect the payment of dividends and
distributions; and otherwise assisting the Fund in the conduct of its business,
subject to the direction and control of the Fund's Board of Trustees.


     Under the Advisory Agreement, which was last approved by the Board of
Trustees on July 17, 1998 and by the shareholders of the Fund on December 17,
1998, the Fund is responsible for other expenses, including organizational
expenses (including out-of-pocket expenses, but not including the Adviser's
overhead or employee costs); brokers' commissions or other costs of acquiring or
disposing of any portfolio securities of the Fund; legal, auditing and
accounting expenses; payment for portfolio pricing or valuation services to
pricing agents, accountants, bankers and other specialists, if any; taxes and

                                       12
<PAGE>   60

those Trustees who are not "interested persons" of the Fund (as defined in the
1940 Act); the cost of printing and distributing reports, notices and dividends
to current shareholders; and the fees and expenses of the Fund's custodians,
subcustodians, dividend disbursing agents and registrars. The Fund may arrange
to have third parties assume all or part of the expenses of sale, underwriting
and distribution of shares of the Fund. The Fund is also responsible for
expenses of shareholders' and other meetings and its expenses incurred in
connection with litigation and the legal obligation it may have to indemnify
officers and Trustees of the Fund with respect thereto. The Fund is also
responsible for the maintenance of books and records which are required to be
maintained by the Fund's custodian or other agents of the Fund; telephone,
telex, facsimile, postage and other communications expenses; any fees, dues and
expenses incurred by the Fund in connection with membership in investment
company trade organizations; expenses of printing and mailing prospectuses and

any other Fund advisors or consultants; expenses relating to investor and public
relations; interest charges, bond premiums and other insurance expense; freight,
insurance and other charges in connection with the shipment of the Fund's
portfolio securities; and other expenses.

     The Adviser is responsible for the payment of the compensation and expenses
of all Trustees, officers and executive employees of the Fund (including the
Fund's share of payroll taxes) affiliated with the Adviser and making available,
without expense to the Fund, the services of such Trustees, officers and
employees as may duly be elected officers of the Fund, subject to their
individual consent to serve and to any limitations imposed by law. The Fund is
responsible for the fees and expenses (specifically including travel expenses
relating to Fund business) of Trustees not affiliated with the Adviser
("Non-Interested Trustees"). Under the Advisory Agreement, the Adviser also pays
the Fund's share of payroll taxes. During the Fund's most recent fiscal year, no
compensation, direct or otherwise (other than through fees paid to the Adviser),
was paid or became payable by the Fund to any of its officers or Trustees who
were affiliated with the Adviser.

     In return for the services provided by the Adviser as investment manager
and the expenses it assumes under the Advisory Agreement, the Fund pays the
Adviser a management fee computed at an annual rate of 0.60% of the Fund's
average weekly net assets. The Fund paid the Adviser $789,000, $772,000 and
$759,000 under the Advisory Agreement for the fiscal periods ending November 30,
1998, 1997 and 1996, respectively.

     The Advisory Agreement further provides that the Adviser shall not be
liable for any error of judgment or mistake of law or for any loss suffered by
the Fund in connection with matters to which such agreement relates, except a
loss resulting from willful misfeasance, bad faith or gross negligence on the
part of the Adviser in the performance of its duties or from reckless disregard
by the Adviser of its obligations and duties under such agreement. The Advisory
Agreement also provides that purchase and sale opportunities, which are suitable
for more than one client of the Adviser, will be allocated by the Adviser in an
equitable manner. Lastly, the Advisory Agreement contains a provision stating
that it supersedes all prior agreements.

     The Advisory Agreement may be terminated without penalty upon sixty (60)
days' written notice by either party. The Fund may agree to terminate its
Advisory Agreement either by the vote of a majority of the outstanding voting
securities of the Fund, or by a vote of the Board. The Advisory Agreement may
also be terminated at any time without penalty by the vote of a majority of the
outstanding voting securities of the Fund or by a vote of the Board if a court
establishes that the Adviser or any of its officers or directors has taken any
action resulting in a breach of the Adviser's covenants under the Advisory
Agreement. As stated above, the Advisory Agreement automatically terminates in
the event of its assignment.

CUSTODIAN, TRANSFER AGENT, DIVIDEND DISBURSING AGENT AND REGISTRAR

     The Fund's securities and cash are held under a custodian agreement by
State Street Bank and Trust Company ("State Street"), whose principal place of
business is 225 Franklin Street, Boston,

                                       13
<PAGE>   61

Massachusetts 02110. Investors Fiduciary Trust Company ("IFTC"), whose principal
place of business is 127 West 10th Street, Kansas City, Missouri 64105, serves
as transfer agent, registrar and dividend disbursing agent for the Fund's common
shares. Pursuant to a services agreement with IFTC, Kemper Service Company, an
affiliate of the Adviser, serves as Shareholder Service Agent for the Fund and,
as such, performs all of IFTC's duties as transfer agent and dividend-paying
agent. The Depository Trust Company ("DTC") will act as Securities Depository
for the Municipal Preferred shares. Bankers Trust Company will act as transfer
agent, registrar, dividend disbursing agent, and redemption agent for the
Municipal Preferred shares.

                             PORTFOLIO TRANSACTIONS

     The Adviser is responsible for decisions to buy and sell securities and
other portfolio holdings for the Fund, the selection of brokers and dealers to
effect the transactions and the negotiation of brokerage commissions, if any.
Fixed-income securities are generally traded on a "net" basis with dealers
acting as principals for their own accounts without a stated commission,
although the price of the security will likely include a profit to the dealer.
In underwritten offerings, securities are usually purchased at a fixed price
which includes an amount of compensation to the underwriter, generally referred
to as the underwriter's concession or discount. On occasion, certain money
market instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid.

     In placing orders for portfolio securities of the Fund, the Adviser is
required to give primary consideration to obtaining the most favorable price and
efficient execution. This means that the Adviser will seek to execute each
transaction at a price and commission, if any, which provides the most favorable
total cost or proceeds reasonably attainable under the circumstances. In seeking
the most favorable price and execution, the Adviser, having in mind the Fund's
best interests, will consider all factors it deems relevant, including, by way
of illustration, price, the size of the transaction, the nature of the market
for the security, the amount of commission, the timing of the transaction taking
into account market prices and trends, the reputation, experience and financial
stability of the broker-dealer involved and the quality of service rendered by
the broker-dealer in other transactions. Though the Adviser generally seeks
reasonably competitive spreads or commissions, the Fund will not necessarily be
paying the lowest spread or commission available. Within the framework of the
policy of obtaining the most favorable price and efficient execution, the
Adviser will consider research and investment services provided by brokers and
dealers who effect or are parties to portfolio transactions with the Fund, the
Adviser or the Adviser's other clients. Such research and investment services
are those which brokerage houses customarily provide to institutional investors
and include statistical and economic data and research reports on particular
issuers and industries. Such services are used by the Adviser in connection with
all of its investment activities, and some of such services obtained in
connection with the execution of transactions for the Fund may be used in
managing other investment accounts. Conversely, brokers furnishing such services
may be selected for the execution of transactions for such other accounts, and
the services furnished by such brokers may be used by the Adviser in providing
investment management for the Fund. Commission rates are established pursuant to
negotiations based on the quality and quantity of execution services provided by
the broker or dealer in light of generally prevailing rates. The management fee
paid by the Fund will not be reduced because the Adviser and/or other clients
receive such services. The allocation of orders and the commission rates paid by
the Fund will be reviewed periodically by the Board of Trustees.

     As permitted by Section 28(e) of the Securities Exchange Act of 1934, as
amended (the "1934 Act"), the Adviser may cause the Fund to pay a broker-dealer
which provides "brokerage and research services" (as defined in the 1934 Act) to
the Adviser, an amount of disclosed commission for effecting a securities
transaction for the Fund in excess of the commission which another broker-dealer
would have charged for effecting that transaction.

     The Fund paid no brokerage commissions during the fiscal years ended
November 30, 1998, 1997 and 1996, as all portfolio transactions were effected on
a principal basis. The rates of portfolio turnover for

                                       14
<PAGE>   62

each of the fiscal years ended November 30, 1998, 1997 and 1996 were
approximately 22%, 13% and 31%, respectively.

                                NET ASSET VALUE

     Net asset value of the Fund will be determined as of the close of regular
trading on the New York Stock Exchange ("NYSE") (generally 4:00 p.m. Eastern
time) on the last Business Day of each week (generally Friday), and at such
other times as the Fund may authorize. The net asset value of the Fund equals
the value of the Fund's assets less the Fund's liabilities. Portfolio securities
for which market quotations are readily available are valued at current market
value. Short-term investments maturing in 60 days or less are valued at
amortized cost when the Adviser determines, pursuant to procedures adopted by
the Board of Trustees, that such cost approximates current market value. All
other securities and assets are valued at their fair value following procedures
adopted by the Board of Trustees.

     In determining net asset value for the Fund, the Fund's custodian utilizes
the valuations of portfolio securities furnished by a Pricing Service approved
by the Board of Trustees. The Pricing Service values portfolio securities at the
mean between the quoted bid and asked price or the yield equivalent when
quotations are readily available. The Pricing Service may employ electronic data
processing techniques or a matrix system, or both, to determine valuations.
Securities for which quotations are not readily available shall be valued at
fair value as determined by the Pricing Service using methods which include
consideration of the following: yields or prices of municipal bonds of
comparable quality, type of issue, coupon, maturity and rating; indications as
to value from dealers; and general market conditions. In the event the Pricing
Service is unable to value a security, the security shall be valued at the lower
of two dealer bids, one of which shall be in writing, obtained by the Fund from
nationally recognized market makers who are members of the National Association
of Securities Dealers, Inc. Futures contracts and options are valued at the most
recent traded price, as of the valuation time, 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 Trustees.

                                  THE AUCTION

     The Certificate of Designation for Preferred Shares of the Fund, adopted by

the Fund) that is not an Existing Holder of such shares or that is an Existing
Holder of such shares that wishes to become the Existing Holder of additional
such shares, (xi) "Rate Period" means the Initial Rate Period of such shares and
any Subsequent Rate Period, including any Special Rate Period, of such shares,
(xii) "Subsequent Rate Period" means any period from and including the first day
following the Initial Rate Period of such shares to but excluding the next
Dividend Payment Date for such shares and any period thereafter from and
including one Dividend Payment Date for such shares to but excluding the next
succeeding Dividend Payment Date for such shares; provided, however, that if any
Subsequent Rate Period is also a Special Rate Period, such term shall mean the
period commencing on the first day of such Special Rate Period and ending on the
last day of the last Dividend Period thereof, (xiii) "Minimum Rate Period" means
any Rate Period consisting of 7 Rate Period Days and (xiv) "Special Rate Period"
means any Subsequent Rate Period commencing on the date designated by the Fund,
as set forth under "Description of Municipal
Preferred -- Dividends -- Designation of Special Rate Periods," and ending on
the last day of the last Dividend Period thereof.

     AUCTION AGENCY AGREEMENT.  The Fund will enter into an agreement (the
"Auction Agency Agreement") with Bankers Trust Company (together with any
successor bank or trust company or other entity entering into a similar
agreement with the Fund, the "Auction Agent") which provides, among other
things, that the Auction Agent will follow the Auction Procedures for purposes
of determining the Applicable Rate for shares of Municipal Preferred so long as
the Applicable Rate for such shares is to be based on the results of an Auction.

     BROKER-DEALER AGREEMENTS.  Each Auction requires the participation of one
or more broker-dealers. The Auction Agent will enter into agreements with
Salomon Smith Barney, Inc. and may enter into similar agreements (collectively,
the "Broker-Dealer Agreements") with one or more additional broker-dealers
(collectively, the "Broker-Dealers") selected by the Fund, which provide for the
participation of Broker-Dealers in Auctions. See "-- Broker-Dealers" below.

     SECURITIES DEPOSITORY.  DTC (together with any successor securities
depository selected by the Fund, the "Securities Depository") will act as the
Securities Depository for the Agent Members with respect to shares of Municipal
Preferred. One certificate for the series of shares of Municipal Preferred will
be registered in the name of Cede & Co. ("Cede"), as nominee of the Securities
Depository. Each certificate will bear a legend to the effect that each
certificate is issued subject to the provisions restricting transfers of shares
of Municipal Preferred contained in the Certificate. The Fund will also issue
stop-transfer instructions to the transfer agent for shares of Municipal
Preferred. Prior to the commencement of the right of holders of Preferred Shares
to elect a majority of the Fund's Trustees, as described below under
"Description of Municipal Preferred -- Voting Rights," Cede will be the holder
of record of all shares of Municipal Preferred, and owners of shares of
Municipal Preferred will not be entitled to receive certificates representing
their ownership interest in such shares.

     DTC, a New York-chartered limited purpose trust company, performs services
for its participants (including the Agent Members), some of whom (and/or their
representatives) own DTC. DTC maintains lists of its participants and will
maintain the positions (ownership interests) held by each such participant (the
"Agent Member") in shares of Municipal Preferred, whether for its own account or
as a nominee for another person.

AUCTION DATES; ADVANCE NOTICE OF ALLOCATION OF TAXABLE INCOME


     The first Auction for shares of Series T Municipal Preferred will be held
on             , 1999, the Business Day preceding the Dividend Payment Date for
the Initial Rate Period of Series T Municipal Preferred. See "Description of
Municipal Preferred -- Dividends." Thereafter, Auctions will normally be held:
(i) every Tuesday, and each Subsequent Rate Period will normally begin on the
following Wednesday for Series T Municipal Preferred; unless the then-current
Rate Period is a Special Rate Period or, in certain circumstances, the day that
would normally be the Auction Date or the first day of such Subsequent Rate
Period is not a Business Day. The Auction Date and the first day of the related
Rate Period (also a Dividend Payment Date) must be Business Days but need not be
consecutive days. See "Description of Municipal Preferred -- Dividends" for
information concerning the circumstances under which the first day of a Rate
Period or the Auction Date, or both, may be moved to a date other than such
specified days.


     Whenever the Fund intends to include any net capital gain or other income
taxable for Federal income tax purposes in any dividend on shares of Municipal
Preferred, the Fund shall, in the case of Minimum Rate Periods or Special Rate
Periods of 28 Rate Period Days or fewer, and may, in the case of any other
Special Rate Period, notify the Auction Agent of the amount to be so included
not later than the Dividend Payment Date next preceding 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, it will be required in turn to
notify each Broker-Dealer, who, on or prior to such Auction Date, in accordance
with its Broker-Dealer Agreement, will be required to notify its customers who
are Beneficial Owners and Potential Beneficial Owners believed by it to be
interested in submitting an Order in the Auction to be held on such Auction
Date. See also "Description of Municipal Preferred -- Dividends -- Gross-up
Payments" below.

ORDERS BY EXISTING HOLDERS AND POTENTIAL HOLDERS

     Prior to the Submission Deadline (as defined under "-- Submission of Orders
by Broker-Dealers to Auction Agent" below) on each Auction Date for shares of
Municipal Preferred:

          (a) each Beneficial Owner of such shares may submit to its
     Broker-Dealer by telephone or otherwise a:

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

             (ii) "Bid" -- indicating the number of outstanding shares of
        Municipal Preferred, if any, that such Beneficial Owner offers to sell
        if the Applicable Rate for such shares for the next succeeding Rate
        Period shall be less than the rate per annum specified by such
        Beneficial Owner in such bid; and/or

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

          (b) Broker-Dealers shall contact customers who are Potential
     Beneficial Owners by telephone or otherwise to determine whether such
     customers desire to submit Bids, in which they will indicate the number of
     shares of Municipal Preferred that they offer to purchase if the Applicable
     Rate for such shares for the next succeeding Rate Period is not less than
     the rate per annum specified in such Bids.

     The communication to a Broker-Dealer of the foregoing information is herein
referred to as an "Order" and collectively as "Orders." A Beneficial Owner or a
Potential Beneficial Owner placing an Order with its Broker-Dealer is herein
referred to as a "Bidder" and collectively as "Bidders." The submission by a
Broker-Dealer of an Order to the Auction Agent shall likewise be referred to
herein as an "Order" and collectively as "Orders," and an Existing Holder or
Potential Holder who places an Order

                                       17
<PAGE>   65

with the Auction Agent or on whose behalf an Order is placed with the Auction
Agent shall likewise be referred to herein as a "Bidder" and collectively as
"Bidders."

     A Beneficial Owner may submit different types of Orders to its
Broker-Dealer with respect to shares of Municipal Preferred then held by such
Beneficial Owner. A Bid placed by a Beneficial Owner specifying a rate higher
than the Applicable Rate determined in the Auction shall constitute an
irrevocable offer to sell the shares subject thereto. A Beneficial Owner that
submits a Bid to its Broker-Dealer having a rate higher than the Maximum Rate on
the Auction Date thereof will be treated as having submitted a Sell Order to its
Broker-Dealer. A Beneficial Owner that fails to submit to its Broker-Dealer
prior to the Submission Deadline for shares of Municipal Preferred an Order or
Orders covering all the outstanding shares of Municipal Preferred held by such
Beneficial Owner will be deemed to have submitted a Hold Order to its
Broker-Dealer covering the number of outstanding shares of Municipal Preferred
held by such Beneficial Owner and not subject to Orders submitted to its
Broker-Dealer; provided, however, that if a Beneficial Owner fails to submit to
its Broker-Dealer prior to the Submission Deadline for shares of Municipal
Preferred an Order or Orders covering all of the outstanding shares of Municipal
Preferred held by such Beneficial Owner for an Auction relating to a Special
Rate Period consisting of more than 28 Rate Period Days, such Beneficial Owner
will be deemed to have submitted a Sell Order to its Broker-Dealer covering the
number of outstanding shares of Municipal Preferred held by such Beneficial
Owner and not subject to Orders submitted to its Broker-Dealer. A Sell Order
shall constitute an irrevocable offer to sell the shares of Municipal Preferred
subject thereto at a price per share equal to $25,000. A Beneficial Owner of
shares of Municipal Preferred that offers to become the Beneficial Owner of
additional shares of Municipal Preferred is, for purposes of such offer, a
Potential Beneficial Owner.

     A Potential Beneficial Owner of shares of Municipal Preferred may submit to
its Broker-Dealer Bids in which it offers to purchase shares of Municipal
Preferred if the Applicable Rate for the next Rate Period is not less than the
rate specified in such Bid. A Bid placed by a Potential Beneficial Owner
specifying a rate not higher than the Maximum Rate shall constitute an
irrevocable offer to purchase the number of shares of Municipal Preferred
specified in such Bid if the rate determined in the Auction is equal to or
greater than the rate specified in such Bid.

     As described more fully below under "-- Submission of Orders by
Broker-Dealers to Auction Agent," the Broker-Dealers will submit the Orders of
their respective customers who are Beneficial Owners and Potential Beneficial
Owners to the Auction Agent, designating themselves (unless otherwise permitted
by the Fund) 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. However, neither the Fund nor the Auction Agent will be
responsible for a Broker-Dealer's failure to comply with the foregoing. Any
Order placed with the Auction Agent by a Broker-Dealer as or on behalf of an
Existing Holder or a Potential Holder will be treated in the same manner as an
Order placed with a Broker-Dealer by a Beneficial Owner or a Potential
Beneficial Owner, as described in the preceding paragraph. Similarly, any
failure by a Broker-Dealer to submit to the Auction Agent an Order in respect of
any shares of Municipal Preferred 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 shares of Municipal Preferred
held by it, as described in the second preceding paragraph. 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" below.

     Neither the Fund nor an affiliate may submit an Order in any Auction,
except that any Broker-Dealer that is an affiliate of the Fund may submit Orders
in an Auction, but only if such Orders are not for its own account.

     The Auction Procedures include a pro rata allocation of shares for purchase
and sale, which may result in an Existing Holder continuing to hold or selling,
or a Potential Holder purchasing, a number of shares of Municipal Preferred that
is fewer than the number of shares of Municipal Preferred specified in its
Order. See "-- Acceptance and Rejection of Submitted Bids and Submitted Sell
Orders and Allocation of Shares" below. To the extent the allocation procedures
have that result, Broker-Dealers that have

                                       18
<PAGE>   66

designated themselves as Existing Holders or Potential Holders in respect of
customer Orders will be required to make appropriate pro rata allocations among
their respective customers. Each purchase or sale shall be made for settlement
on the Business Day next succeeding the Auction Date at a price per share equal
to $25,000. See "-- Notification of Results; Settlement" below.

     As described above, any Bid specifying a rate higher than the Maximum Rate
(as defined below) will (i) be treated as a Sell Order if submitted by a
Beneficial Owner or an Existing Holder and (ii) not be accepted if submitted by
a Potential Beneficial Owner or a Potential Holder. Accordingly, the Auction
Procedures establish the Maximum Rate as a maximum rate per annum that can
result from an Auction. 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" below.

     As used herein, "Maximum Rate," when used with respect to shares of
Municipal Preferred on an Auction Date, means:

          (i) in the case of any Auction Date which is not the Auction Date
     immediately prior to the first day of any proposed Special Rate Period, the
     product of (1) the Reference Rate on such Auction Date for the next Rate
     Period and (2) the Rate Multiple on such Auction Date, unless such shares
     have or had a Special Rate Period (other than a Special Rate Period of 28
     Rate Period Days or fewer) and an Auction at which Sufficient Clearing Bids
     existed has not yet occurred for a Minimum Rate Period after such Special
     Rate Period, in which case the higher of:

             (A) the dividend rate on such shares for the then-ending Rate
        Period; and

             (B) the product of (x) the higher of (I) the Reference Rate on such
        Auction Date for a Rate Period equal in length to the then-ending Rate
        Period, if such then-ending Rate Period was 364 Rate Period Days or
        fewer, or the Treasury Note Rate on such Auction Date for a Rate Period
        equal in length to the then-ending Rate Period, if such then-ending Rate
        Period was more than 364 Rate Period Days, and (II) the Reference Rate
        on such Auction Date for a Rate Period equal in length to such Special
        Rate Period, if such Special Rate Period was 364 Rate Period Days or
        fewer, or the Treasury Note Rate on such Auction Date for a Rate Period
        equal in length to such Special Rate Period, if such Special Rate Period
        was more than 364 Rate Period Days and (y) the Rate Multiple on such
        Auction Date; or

          (ii) in the case of any Auction Date which is the Auction Date
     immediately prior to the first day of any proposed Special Rate Period, the
     product of (1) the highest of (x) the Reference Rate on such Auction Date
     for a Rate Period equal in length to the then-ending Rate Period, if such
     then-ending Rate Period was 364 Rate Period Days or fewer, or the Treasury
     Note Rate on such Auction Date for a Rate Period equal in length to the
     then-ending Rate Period, if such then-ending Rate Period was more than 364
     Rate Period Days, (y) the Reference Rate on such Auction Date for the
     Special Rate Period for which the Auction is being held if such Special
     Rate Period is 364 Rate Period Days or fewer or the Treasury Note Rate on
     such Auction Date for the Special Rate Period for which the Auction is
     being held if such Special Rate Period is more than 64 Rate Period Days,
     and (z) the Reference Rate on such Auction Date for Minimum Rate Periods
     and (2) the Rate Multiple on such Auction Date.

     As used herein, "Reference Rate" shall mean (i) the higher of the Taxable
Equivalent of the Short-Term Municipal Bond Rate and the "AA" Composite
Commercial Paper Rate in the case of Minimum Rate Periods and Special Rate
Periods of 28 Rate Period Days or fewer; (ii) the "AA" Composite Commercial
Paper Rate in the case of Special Rate Periods of more than 28 Rate Period Days
but fewer than 183 Rate Period Days; and (iii) the Treasury Bill Rate in the
case of Special Rate Periods of more than 182 Rate Period Days but fewer than
365 Rate Period Days.

     As used herein, "Taxable Equivalent of the Short-Term Municipal Bond Rate,"
on any date for any Minimum Rate Period or Special Rate Period of 28 Rate Period
Days or fewer, shall mean 90% of the quotient of (A) the per annum rate
expressed on an interest equivalent basis equal to the S&P Kenny
                                       19
<PAGE>   67

30 day High Grade Index or any successor index (the "Kenny Index") (provided,
however, that any such successor index must be approved by Moody's (if Moody's
is then rating the shares of Municipal Preferred) and S&P (if S&P is then rating
the shares of Municipal Preferred)), made available for the Business Day
immediately preceding such date but in any event not later than 8:30 A.M.,
Eastern time, on such date by S&P J.J. Kenny Evaluation Services or any
successor thereto, based upon 30-day yield evaluations at par of short-term
bonds, the interest on which is excludable for regular Federal income tax
purposes under the Code, of "high grade" component issuers selected by S&P J.J.
Kenny Evaluation Services or any such successor from time to time in its
discretion, which component issuers shall include, without limitation, issuers
of general obligation bonds but shall exclude any bonds the interest on which
constitutes an item of tax preference under Section 57(a)(5) of the Code, or
successor provisions, for purposes of the "alternative minimum tax," divided by
(B) 1.00 minus the maximum marginal regular Federal individual income tax rate
applicable to ordinary income or the maximum marginal regular Federal corporate
income tax rate applicable to ordinary income (in each case expressed as a
decimal), whichever is greater; provided, however, that if the Kenny Index is
not made so available by 8:30 A.M., Eastern time, on such date by S&P J.J. Kenny
Evaluation Services or any successor, the Taxable Equivalent of the Short-Term
Municipal Bond Rate shall mean the quotient of (A) the per annum rate expressed
on an interest equivalent basis equal to the most recent Kenny Index so made
available for any preceding Business Day, divided by (B) 1.00 minus the maximum
marginal regular Federal individual income tax rate applicable to ordinary
income or the maximum marginal regular Federal corporate income tax rate
applicable to ordinary income (in each case expressed as a decimal), whichever
is greater.

     As used herein, 'AA' Composite Commercial Paper Rate," on any date for any
Rate Period, means:

          (i)(A) in the case of any Minimum Rate Period or any Special Rate
     Period of fewer than 49 Rate Period Days, the interest equivalent of the
     30-day rate; provided, however, that if such Rate Period is a Minimum Rate
     Period and the "AA" Composite Commercial Paper Rate is being used to
     determine the Applicable Rate when all of the outstanding shares of
     Municipal Preferred are subject to Submitted Hold Orders, then the interest
     equivalent of the seven-day rate, and (B) in the case of any Special Rate
     Period of (1) 49 or more but fewer than 70 Rate Period Days, the interest
     equivalent of the 60-day rate; (2) 70 or more but fewer than 85 Rate Period
     Days, the arithmetic average of the interest equivalent of the 60-day and
     90-day rates; (3) 85 or more but fewer than 99 Rate Period Days, the
     interest equivalent of the 90-day rate; (4) 99 or more but fewer than 120
     Rate Period Days, the arithmetic average of the interest equivalent of the
     90-day and 120-day rates; (5) 120 or more but fewer than 141 Rate Period
     Days, the interest equivalent of the 120-day rate; (6) 141 or more but
     fewer than 162 Rate Period Days, the arithmetic average of the 120-day and
     180-day rates; and (7) 162 or more but fewer than 183 Rate Period Days, the
     interest equivalent of the 180-day rate, in each case on commercial paper
     placed on behalf of issuers whose corporate bonds are rated "AA" by S&P or
     the equivalent of such rating by S&P or another rating agency, as made
     available on a discount basis or otherwise by the Federal Reserve Bank of
     New York for the Business Day immediately preceding such date; or

          (ii) in the event that the Federal Reserve Bank of New York does not
     make available any such rate, then the arithmetic average of such rates, as
     quoted on a discount basis or otherwise, by the Commercial Paper Dealers to
     the Auction Agent for the close of business on the Business Day next
     preceding such date.

     If any Commercial Paper Dealer does not quote a rate required to determine
the "AA" Composite Commercial Paper Rate, the "AA" Composite Commercial Paper
Rate shall be determined on the basis of the quotation or quotations furnished
by the remaining Commercial Paper Dealer or Commercial Paper Dealers and any
Substitute Commercial Paper Dealer or Substitute Commercial Paper Dealers
selected by the Fund to provide such rate or rates not being supplied by any
Commercial Paper Dealer or Commercial Paper Dealers, as the case may be, or, if
the Fund does not select any such Substitute Commercial Paper Dealer or
Substitute Commercial Paper Dealers, by the remaining Commercial Paper Dealer or
Commercial Paper Dealers. For purposes of this definition, the "interest
equivalent" of a rate stated on a discount basis (a "discount rate") for
commercial paper of a given days' maturity shall be equal to the
                                       20
<PAGE>   68

quotient (rounded upwards to the next higher one-thousandth (0.001) of 1%) of
(A) the discount rate divided by (B) the difference between (x) 1.00 and (y) a
fraction the numerator of which shall be the product of the discount rate times
the number of days in which such commercial paper matures and the denominator of
which shall be 360. As used herein, "Commercial Paper Dealers" means Lehman
Commercial Paper Incorporated, Goldman, Sachs & Co. and Merrill Lynch, Pierce,
Fenner & Smith Incorporated and such other commercial paper dealer or dealers as
the Fund may from time to time appoint, or, in lieu of any thereof, their
respective affiliates or successors, if such entity is a commercial paper
dealer. As used herein, "Substitute Commercial Paper Dealer" means CS First
Boston and Morgan Stanley & Co. Incorporated or their respective affiliates or
successors, if such entity is a commercial paper dealer, provided that none of
such entities shall be a Commercial Paper Dealer.

     As used herein, "Treasury Bill Rate," on any date for any Rate Period,
means:

          (i) the bond equivalent yield, calculated in accordance with
     prevailing industry convention, of the rate on the most recently auctioned
     Treasury Bill with a remaining maturity closest to the length of such Rate
     Period, as quoted in The Wall Street Journal on such date for the Business
     Day next preceding such date; or

          (ii) in the event that any such rate is not published in The Wall
     Street Journal, then the bond equivalent yield, calculated in accordance
     with prevailing industry convention, as calculated by reference to the
     arithmetic average of the bid price quotations of the most recently
     auctioned Treasury Bill with a remaining maturity closest to the length of
     such Rate Period, as determined by bid price quotations as of the close of
     business on the Business Day immediately preceding such date obtained from
     the U.S. Government Securities Dealers to the Auction Agent.

     As used herein, "Treasury Note Rate," on any date for any Rate Period,
means:

          (i) the yield on the most recently auctioned Treasury Note with a
     remaining maturity closest to the length of such Rate Period, as quoted in
     The Wall Street Journal on such date for the Business Day next preceding
     such date; or

          (ii) in the event that any such rate is not published in The Wall
     Street Journal, then the yield as calculated by reference to the arithmetic
     average of the bid price quotations of the most recently auctioned Treasury
     Note with a remaining maturity closest to the length of such Rate Period,
     as determined by bid price quotations as of the close of business on the
     Business Day immediately preceding such date obtained from the U.S.
     Government Securities Dealers to the Auction Agent.

     For purposes of the foregoing, "Treasury Bill" means a direct obligation of
the U.S. government having a maturity at the time of issuance of 364 days or
less, and "Treasury Note" means a direct obligation of the U.S. government
having a maturity at the time of issuance of five years or less but more than
364 days. If any U.S. Government Securities Dealer does not quote a rate
required to determine the Treasury Bill Rate or the Treasury Note Rate, such
rate shall be determined on the basis of the quotation or quotations furnished
by the remaining U.S. Government Securities Dealer or U.S. Government Securities
Dealers and any Substitute U.S. Government Securities Dealers selected by the
Fund to provide such rate or rates not being supplied by any U.S. Government
Securities Dealer or U.S. Government Securities Dealers, as the case may be, or,
if the Fund does not select any such Substitute U.S. Government Securities
Dealer or Substitute U.S. Government Securities Dealers, by the remaining U.S.
Government Securities Dealer or U.S. Government Securities Dealers. As used
herein, "U.S. Government Securities Dealer" means Lehman Government Securities
Incorporated, Goldman, Sachs & Co., Salomon Smith Barney Inc. and Morgan
Guaranty Trust Company of New York or their respective affiliates or successors,
if such entity is a U.S. government securities dealer. As used herein,
"Substitute U.S. Government Securities Dealer" shall mean CS First Boston
Corporation and Merrill Lynch, Pierce, Fenner & Smith Incorporated or their
respective affiliates or successors, if such entity is a U.S. government
securities dealer, provided however, that none of such entities shall be a U.S.
Government Securities Dealer.

                                       21
<PAGE>   69

     The applicable "AA" Composite Commercial Paper Rates, Taxable Equivalent of
the Short-Term Municipal Bond Rates, Treasury Bill Rates and Treasury Note Rates
will be the rates announced on such Auction Date for the Business Day
immediately prior to such Auction Date.

     The "Rate Multiple" will be a percentage, determined as set forth below,
based on the prevailing rating of shares of Municipal Preferred in effect at the
close of business on the Business Day next preceding such Auction Date:

<TABLE>
<CAPTION>
PREVAILING RATING                                             PERCENTAGE

Ba3/BB-.....................................................     200%
Below Ba3/BB-...............................................     250%
</TABLE>

provided, however, that in the event the Fund has notified the Auction Agent of
its intent to allocate income taxable for Federal income tax purposes to shares
of Municipal Preferred prior to the Auction establishing the Applicable Rate for
such shares, the applicable percentage in the foregoing table shall be divided
by the quantity 1 minus the maximum marginal regular Federal individual income
tax rate applicable to ordinary income or the maximum marginal regular Federal
corporate income tax rate applicable to ordinary income, whichever is greater.
If the shares of Municipal Preferred are rated by only one rating agency, such
rating will be the prevailing rating.

     For purposes of this definition, the "prevailing rating" of shares of
Municipal Preferred shall be (i) Aa3/AA- or higher if such shares have a rating
of Aa3 or better by Moody's and AA- or better by S&P or the equivalent of such
ratings by such agencies or a substitute rating agency or substitute rating
agencies selected as provided below, (ii) if not Aa3/AA- or higher, then A3/A-
if such shares have a rating of A3 or better by Moody's and A- or better by S&P
or the equivalent of such ratings by such agencies or a substitute rating agency
or substitute rating agencies selected as provided below, (iii) if not Aa3/AA-
or higher or A3/A-, then Baa3/BBB- if such shares have a rating of Baa3 or
better by Moody's and BBB- or better by S&P or the equivalent of such ratings by
such agencies or a substitute rating agency or substitute rating agencies
selected as provided below, (iv) if not Aa3/AA- or higher, A3/A- or Baa3/BBB-,
then Ba3/BB- if such shares have a rating of Ba3 or better by Moody's and BB- or
better by S&P or the equivalent of such ratings by such agencies or a substitute
rating agency or substitute rating agencies selected as provided below, and (v)
if not Aa3/AA- or higher, A3/A-, Baa3/BBB-, or Ba3/BB-, then below Ba3/BB-;
provided, however, that if such shares are rated by only one rating agency, the
prevailing rating shall be determined without reference to the rating of any
other rating agency. The Fund will take all reasonable action necessary to
enable either S&P or Moody's to provide a rating for shares of Municipal
Preferred. If neither S&P nor Moody's shall make such a rating available,
Salomon Smith Barney Inc. or its successor shall select at least one nationally
recognized statistical rating organization (as that term is used in the rules
and regulations of the SEC under the Securities Exchange Act of 1934, as
amended) to act as a substitute rating agency in respect of the shares of
Municipal Preferred, and the Fund shall take all reasonable action to enable
such rating agency to provide a rating for such shares.

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 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, as the case may be, in respect of the shares of Municipal
Preferred 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.

                                       22
<PAGE>   70

     If any rate specified in any Bid contains more than three figures to the
right of the decimal point, the Auction Agent will round such rate to the next
highest one-thousandth (0.001) of 1%.

     If one or more Orders of an Existing Holder is submitted to the Auction
Agent covering in the aggregate more than the number of outstanding shares of
Municipal Preferred subject to an Auction held by such Existing Holder, such
Orders will be considered valid in the following order of priority:

          (a) all Hold Orders will be considered valid, but only up to and
     including in the aggregate the number of shares of Municipal Preferred held
     by such Existing Holder, and, if the number of shares subject to such Hold
     Orders exceeds the number of shares held by such Existing Holder, the
     number of shares subject to each such Hold Order shall be reduced pro rata
     to cover the number of shares held by such Existing Holder;

          (b) (i) any Bid will be considered valid up to and including the
     excess of the number of shares of Municipal Preferred held by such Existing
     Holder over the number of shares of Municipal Preferred subject to any Hold
     Orders referred to in clause (a) above;

             (ii) subject to subclause (i), if more than one Bid of an Existing
        Holder is submitted to the Auction Agent with the same rate and the
        number of shares of Municipal Preferred subject to such Bids is greater
        than such excess, such Bids will be considered valid up to and including
        the amount of such excess, and the number of shares of Municipal
        Preferred subject to each Bid with the same rate will be reduced pro
        rata to cover the number of shares of Municipal Preferred equal to such
        excess;

             (iii) subject to subclauses (i) and (ii), if more than one Bid of
        an Existing Holder is submitted to the Auction Agent with different
        rates, such Bids shall be considered valid in the ascending order of
        their respective rates up to and including the amount of such excess;
        and

             (iv) in any such event, the number, if any, of such shares subject
        to any portion of Bids considered not valid in whole or in part under
        this clause (b) will be treated as the subject of a Bid by or on behalf
        of a Potential Holder at the rate specified therein; and

          (c) all Sell Orders will be considered valid up to and including the
     excess of the number of outstanding shares of Municipal Preferred held by
     such Existing Holder over the sum of shares of Municipal Preferred subject
     to valid Hold Orders referred to in clause (a) above and valid Bids
     referred to in clause (b) above.

     If more than one Bid of a Potential Holder for shares of Municipal
Preferred is submitted to the Auction Agent by or on behalf of any Potential
Holder, each Bid submitted will be a separate Bid with the rate and number of
shares therein specified.

DETERMINATION OF SUFFICIENT CLEARING BIDS, WINNING BID RATE AND APPLICABLE RATE

     Not earlier than the Submission Deadline on each Auction Date for shares of
the series of Municipal Preferred, the Auction Agent will assemble all valid
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
being herein 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
collectively as "Submitted Hold Orders," "Submitted Bids" or "Submitted Sell
Orders," as the case may be, or as "Submitted Orders") and will determine the
excess of the number of outstanding shares of Municipal Preferred over the
number of outstanding shares of Municipal Preferred subject to Submitted Hold
Orders (such excess being herein referred to as the "Available Municipal
Preferred") and whether Sufficient Clearing Bids have been made in the Auction.
"Sufficient Clearing Bids" will have been made if the number of outstanding
shares of Municipal Preferred that are the subject of Submitted Bids of
Potential Holders specifying rates not higher than the Maximum Rate equals or
exceeds the number of outstanding shares of Municipal Preferred that are the
subject of Submitted Sell Orders (including the number of shares subject to Bids
of Existing Holders specifying rates higher than the Maximum Rate).

                                       23
<PAGE>   71

     If Sufficient Clearing Bids have been made, the Auction Agent will
determine the lowest rate specified in the Submitted Bids (the "Winning Bid
Rate") which, taking into account the rates in the Submitted Bids of Existing
Holders, would result in Existing Holders continuing to hold an aggregate number
of outstanding shares of Municipal Preferred which, when added to the number of
outstanding shares of Municipal Preferred to be purchased by Potential Holders,
based on the rates in their Submitted Bids, would equal not less than the
Available Municipal Preferred. In such event, the Winning Bid Rate will be the
Applicable Rate for the next Rate Period for all shares of Municipal Preferred.

     If Sufficient Clearing Bids have not been made (other than because all of
the outstanding shares of Municipal Preferred are subject to Submitted Hold
Orders), the Applicable Rate for the next Rate Period for all shares of
Municipal Preferred will be equal to the Maximum Rate. If Sufficient Clearing
Bids have not been made, Beneficial Owners that have submitted or that are
deemed to have submitted Sell Orders may not be able to sell in the Auction all
shares of Municipal Preferred subject to such Sell Orders but will continue to
own shares of Municipal Preferred for the next Rate Period, dividends for which
may include income taxable to such Beneficial Owners. See "-- Auction Dates;
Advance Notice of Allocation of Taxable Income" above and "-- Acceptance and
Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares"
below.

     If all of the outstanding shares of Municipal Preferred are subject to
Submitted Hold Orders, the Applicable Rate for the next Rate Period will be the
lesser of the Kenny Index (if such Rate Period consists of fewer than 183 Rate
Period Days) or the product of (i)(1) the "AA" Composite Commercial Paper Rate
on the Auction Date for such Rate Period, if such Rate Period consists of fewer
than 183 Rate Period Days; (2) the Treasury Bill Rate on such Auction Date for
such Rate Period, if such Rate Period consists of more than 182 but fewer than
365 Rate Period Days; or (3) the Treasury Note Rate on such Auction Date for
such Rate Period, if such Rate Period is more than 364 Rate Period Days (the
rate described in the foregoing clause (i)(1), (2) or (3) as applicable, being
referred to herein as the "Benchmark Rate") and (ii) 1 minus the maximum
marginal regular Federal individual income tax rate applicable to ordinary
income or the maximum marginal regular Federal corporate income tax rate
applicable to ordinary income, whichever is greater; provided, however, that if
the Fund has notified the Auction Agent of its intent to allocate to shares of
Municipal Preferred in such Rate Period any net capital gain or other income
taxable for Federal income tax purposes ("Taxable Income"), the Applicable Rate
for shares of Municipal Preferred for such Rate Period will be (A) if the
Taxable Yield Rate (as defined below) is greater than the Benchmark Rate, then
the Benchmark Rate, or (B) if the Taxable Yield Rate is less than or equal to
the Benchmark Rate, then the rate equal to the sum of (x) the lesser of the
Kenny Index (if such Rate Period consists of fewer than 183 Rate Period Days) or
the product of the Benchmark Rate multiplied by the factor set forth in the
preceding clause (ii) and (y) the product of the maximum marginal regular
Federal individual income tax rate applicable to ordinary income or the maximum
marginal regular Federal corporate income tax applicable to ordinary income,
whichever is greater, multiplied by the Taxable Yield Rate. For purposes of the
foregoing, "Taxable Yield Rate" means the rate determined by (a) dividing the
amount of Taxable Income available for distribution per share of Municipal
Preferred by the number of days in the Dividend Period in respect of which such
Taxable Income is contemplated to be distributed, (b) multiplying the amount
determined in (a) above by 365 (in the case of a Dividend Period of 7 Rate
Period Days) or 360 (in the case of any other Dividend Period), and (c) dividing
the amount determined in (b) above by $25,000. In calculating the "AA" Composite
Commercial Paper Rate, the Treasury Bill Rate and the Treasury Note Rate for
such purpose, the rates used will be the rates or yields specified in the
applicable definitions of "AA" Composite Commercial Paper Rate, Treasury Bill
Rate and Treasury Note Rate set forth under "-- Orders by Existing Holders and
Potential Holders."

ACCEPTANCE AND REJECTION OF SUBMITTED BIDS AND SUBMITTED SELL ORDERS AND
ALLOCATION OF SHARES

     Based on the determinations made under "-- Determination of Sufficient
Clearing Bids, Winning Bid Rate and Applicable Rate" above and, subject to the
discretion of the Auction Agent to round and allocate certain shares as
described below, Submitted Bids and Submitted Sell Orders will be accepted or

                                       24
<PAGE>   72

rejected in the order of priority set forth in the Auction Procedures, with the
result that Existing Holders and Potential Holders of shares of Municipal
Preferred will sell, continue to hold and/or purchase such shares as set forth
below. Existing Holders that submitted or were deemed to have submitted Hold
Orders (or on whose behalf Hold Orders were submitted or deemed to have been
submitted) will continue to hold the shares of Municipal Preferred subject to
such Hold Orders.

     If Sufficient Clearing Bids have been made:

          (a) Each Existing Holder that placed or on whose behalf was placed a
     Submitted Sell Order or Submitted Bid specifying any rate higher than the
     Winning Bid Rate will sell the outstanding shares of Municipal Preferred
     subject to such Submitted Sell Order or Submitted Bid;

          (b) Each Existing Holder that placed or on whose behalf was placed a
     Submitted Bid specifying a rate lower than the Winning Bid Rate will
     continue to hold the outstanding shares of Municipal Preferred subject to
     such Submitted Bid;

          (c) Each Potential Holder that placed or on whose behalf was placed a
     Submitted Bid specifying a rate lower than the Winning Bid Rate will
     purchase the number of outstanding shares of Municipal Preferred subject to
     such Submitted Bid;

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

          (e) Each Potential Holder that placed or on whose behalf was placed a
     Submitted Bid specifying a rate equal to the Winning Bid Rate will purchase
     any shares of Available Municipal Preferred not accounted for in clauses
     (b) through (d) above on a pro rata basis based on the outstanding shares
     of Municipal Preferred subject to all such Submitted Bids.

     If Sufficient Clearing Bids have not been made (unless this results because
all outstanding shares of Municipal Preferred are subject to Submitted Hold
Orders):

          (a) Each Existing Holder that placed or on whose behalf was placed a
     Submitted Bid specifying a rate equal to or lower than the Maximum Rate
     will continue to hold the outstanding shares of Municipal Preferred subject
     to such Submitted Bid;

          (b) Each Potential Holder that placed or on whose behalf was placed a
     Submitted Bid specifying a rate equal to or lower than the Maximum Rate
     will purchase the number of outstanding shares of Municipal Preferred
     subject to such Submitted Bid; and

          (c) Each Existing Holder that placed or on whose behalf was placed a
     Submitted Bid specifying a rate higher than the Maximum Rate or a Submitted
     Sell Order will sell a number of shares of Municipal Preferred determined
     on a pro rata basis based on the number of outstanding shares of Municipal
     Preferred subject to all such Submitted Bids and Submitted Sell Orders.

     If, as a result of the pro rata allocation described in clauses (d) or (e)
of the second preceding paragraph or clause (c) of the next preceding paragraph,
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
Municipal Preferred, the Auction Agent will, in such manner as, in its sole
discretion, it will determine, round up or down to the nearest whole share the
number of shares of Municipal Preferred being sold or purchased on such Auction
Date so that the number of shares sold or purchased by each Existing Holder or
Potential Holder will be whole shares of Municipal Preferred. If as a result of
the pro rata allocation

                                       25
<PAGE>   73

described in clause (e) of the second preceding paragraph, any Potential Holder
would be entitled or required to purchase less than a whole share of Municipal
Preferred, the Auction Agent will, in such manner as, in its sole discretion, it
will determine, allocate shares of Municipal Preferred for purchase among
Potential Holders so that only whole shares of Municipal Preferred are purchased
by any such Potential Holder, even if such allocation results in one or more of
such Potential Holders not purchasing shares of Municipal Preferred.

NOTIFICATION OF RESULTS; SETTLEMENT

     The Auction Agent will be required to advise each Broker-Dealer that
submitted an Order of the Applicable Rate for the next Rate Period and, if the
Order was a Bid or Sell Order, whether such Bid or Sell Order was accepted or
rejected, in whole or in part, by telephone by approximately 3:00 P.M., Eastern
time, on each Auction Date. Each Broker-Dealer that submitted an Order for the
account of a customer will then be required to advise such customer of the
Applicable Rate for the next Rate Period and, if such Order was a Bid or a Sell
Order, whether such Bid or Sell Order was accepted or rejected, in whole or in
part, will be required to confirm purchases and sales with each customer
purchasing or selling shares of Municipal Preferred as a result of the Auction
and will be required to advise each customer purchasing or selling shares of
Municipal Preferred as a result of the Auction 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. The Auction Agent will be required to record each transfer of
shares of Municipal Preferred on the registry of Existing Holders to be
maintained by the Auction Agent. See "-- General" above.

     In accordance with the Securities Depository's normal procedures, on the
Business Day after the 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 and
shares delivered as necessary to effect the purchases and sales of shares of
Municipal Preferred as determined in the 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 against delivery by their Agent Members in same-day funds. The
settlement procedures to be used with respect to Auctions for shares of
Municipal Preferred are set forth in Appendix C hereto.

     If any Existing Holder selling shares of Municipal Preferred in an Auction
fails to deliver such shares, the Broker-Dealer of any person that was to have
purchased shares of Municipal Preferred in such Auction may deliver to such
person a number of whole shares of Municipal Preferred 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 Municipal Preferred to be so delivered shall be
determined by such Broker-Dealer. Delivery of such lesser number of shares shall
constitute good delivery.

CONCERNING THE AUCTION AGENT

     The Auction Agent is acting 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
Agency Agreement and will not be liable for any error of judgment made in good
faith unless the Auction Agent will have been negligent in ascertaining the
pertinent facts.

     The Auction Agent may rely upon, as evidence of the identities of the
Existing Holders of shares of Municipal Preferred, a list of initial owners of
such shares provided by the Fund, the results of Auctions, notices from any
Broker-Dealer (or other Person, if permitted by the Fund) with respect to
transfers described in the Prospectus under "The Auction -- Secondary Market
Trading and Transfer of Municipal Preferred" and notices from the Fund. The
Auction Agent is not required to accept any such notice for an Auction unless it
is received by the Auction Agent by 3:00 P.M., Eastern time, on the Business Day
preceding such Auction.

                                       26
<PAGE>   74

     The Auction Agent will be the transfer agent, registrar, dividend
disbursing agent and redemption agent for shares of Municipal Preferred. The
registrar for shares of Municipal Preferred will send notices to Holders of
shares of Municipal Preferred of any special meetings at which Holders of
Municipal Preferred have the right to elect Trustees of the Fund. See
"Description of Municipal Preferred -- Voting Rights" below.

     The Auction Agent may terminate the Auction Agency Agreement upon notice to
the Fund on a date no earlier than 60 days after such notice. If the Auction
Agent should resign, 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 Agency Agreement. The Fund may remove the Auction
Agent provided that prior to such removal the Fund shall have entered into such
an agreement with a successor Auction Agent.

BROKER-DEALERS

     The Auction Agent after each Auction for shares of Municipal Preferred will
pay to each Broker-Dealer, from funds provided by the Fund, a service charge at
the annual rate of 1/4 of 1% in the case of any Auction immediately preceding a
Rate Period of less than one year, or a percentage agreed to by the Fund and the
Broker-Dealers in the case of any Auction immediately preceding a Rate Period of
one year or longer, of the purchase price of shares of Municipal Preferred
placed by such Broker-Dealer at such Auction. For the purposes of the preceding
sentence, shares of Municipal Preferred will be placed by a Broker-Dealer if
such shares were (i) the subject of Hold Orders deemed to have been submitted to
the Auction Agent by the Broker-Dealer and were acquired by such Broker-Dealer
for its own account or were acquired by such Broker-Dealer for its customers who
are Beneficial Owners or (ii) the subject of an Order submitted by such
Broker-Dealer that is (A) a Submitted Bid of an Existing Holder that resulted in
such Existing Holder continuing to hold such shares as a result of the Auction
or (B) a Submitted Bid of a Potential Holder that resulted in such Potential
Holder purchasing such shares as a result of the Auction or (C) a valid Hold
Order.

     The Fund may request the Auction Agent to terminate one or more
Broker-Dealer Agreements at any time, provided that at least one Broker-Dealer
Agreement is in effect after such termination.

     The Broker-Dealer Agreements provide that a Broker-Dealer (other than an
affiliate of the Fund) may submit Orders in Auctions for its own account, unless
the Fund notifies all Broker-Dealers that they may no longer do so, in which
case Broker-Dealers may continue to submit Hold Orders and Sell Orders for their
own accounts. Any Broker-Dealer that is an affiliate of the Fund may submit
Orders in Auctions, but only if such Orders are not for its own account. If a
Broker-Dealer submits an Order for its own account in any Auction, it might have
an advantage over other Bidders because it would have knowledge of all Orders
submitted by it in that Auction; such Broker-Dealer, however, would not have
knowledge of Orders submitted by other Broker-Dealers in that Auction.

     The Broker-Dealers expect, but are not obligated, to maintain a secondary
trading market in shares of Municipal Preferred outside of Auctions. There can
be no assurance that a secondary trading market in shares of Municipal Preferred
will develop or, if it does develop, that it will provide owners with liquidity
of investment. The shares of Municipal Preferred will not be registered on any
stock exchange or on the National Association of Securities Dealers Automated
Quotations system.

                       DESCRIPTION OF MUNICIPAL PREFERRED


     The descriptions of the shares of Municipal Preferred contained in the
Certificate and this SAI do not purport to be complete and are subject to and
qualified in their entireties by reference to the Amended and Restated Agreement
and Declaration of Trust (the "Declaration of Trust"). Copies of the Certificate
and Declaration of Trust are filed as exhibits to the Registration Statement of
which the Prospectus and this SAI are a part and may be inspected, and copies
thereof may be obtained, as described under "Further Information" in the
Prospectus.


GENERAL

     The shares of Municipal Preferred will rank on a parity with each other and
with shares of any other series of Preferred Shares as to the payment of
dividends and the distribution of assets upon dissolution, liquidation or
winding up of the affairs of the Fund.

DIVIDENDS


     GENERAL.  The Holders of shares of Municipal Preferred offered pursuant to
the Prospectus will be entitled to receive, when, as and if declared by the
Board of Trustees, out of funds legally available therefor in accordance with
the Declaration of Trust, the Certificate and applicable law, cumulative cash
dividends at the Applicable Rate thereof, determined as set forth below under
"-- Determination of Dividend Rate," and no more (except as otherwise provided
below under "Gross-up Payments"), payable on the respective dates determined as
set forth below. No interest, or sum of money in lieu of interest, will be
payable in respect of any dividend payment or payments on shares of Municipal
Preferred which may be in arrears, and, except as otherwise provided herein, no
additional sum of money will be payable in respect of any such arrearage.
Dividends on shares of Municipal Preferred shall accumulate at the Applicable
Rate from the Date of Original Issue and, except as provided below, shall be
payable on             , 1999, and thereafter on each Wednesday for the Series T
Municipal Preferred; provided, however, that (1) if the Wednesday on which
dividends would otherwise be payable as set forth above for the Series T
Municipal Preferred is not a Business Day, then dividends shall be payable
instead on the first Business Day that falls after such Wednesday and (2) the
Fund in its discretion may establish Dividend Payment Dates in respect of any
Special Rate Period of such shares consisting of more than 28 Rate Period Days
that differ from those set forth above; provided, however, that such dates shall
be set forth in the Notice of Special Rate Period relating to such Special Rate
Period, as delivered to the Auction Agent and filed with the Secretary of the
Fund; and further provided that (1) any such Dividend Payment Date shall be a
Business Day and (2) the last Dividend Payment Date in respect of such Special
Rate Period shall be the Business Day immediately following the last day
thereof, as such last day is determined as set forth below under "-- Designation
of Special Rate Periods."


     The amount of dividends per share payable on shares of Municipal Preferred
on any date on which dividends shall be payable on such shares shall be computed
by multiplying the Applicable Rate in effect for such Dividend Period or
Dividend Periods or part thereof for which dividends have not been paid by a
fraction, the numerator of which shall be the number of days in such Dividend
Period or Dividend Periods or part thereof and the denominator of which shall be
365 if such Dividend Period consists of 7 Rate Period Days and 360 for all other
Dividend Periods, and applying the rate obtained against $25,000. Any dividend
payment made on shares of Municipal Preferred shall first be credited against
the earliest accumulated but unpaid dividends due with respect to such shares.

     Each dividend on shares of Municipal Preferred will be paid on the Dividend
Payment Date therefor to the Holders of record as their names appear on the
record books of the Fund on the Business Day next preceding such 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 of record as their names appear on the record books of the Fund on
such date, not exceeding 15 days preceding the payment date thereof, as may be
fixed by the Board of Trustees.

                                       28
<PAGE>   76

     The Securities Depository, in accordance with its current procedures, is
expected to credit on each Dividend Payment Date dividends received from the
Fund to the accounts of the respective Agent Members in next-day funds. Each of
the initial Broker-Dealers, however, has represented to the Fund that such
Broker-Dealer (or if such Broker-Dealer does not act as Agent Member, the Agent
Member designated by such Broker-Dealer) will make such dividend payments
available in same-day funds on each Dividend Payment Date to Beneficial Owners
that use such Broker-Dealer or its designee as Agent Member. A Beneficial Owner
of shares of Municipal Preferred that does not use one of the initial Broker-
Dealers or a designee thereof as its Agent Member should contact the Agent
Member used by such Beneficial Owner to determine whether such Agent Member will
make dividend payments available to such Beneficial Owner in next-day or
same-day funds. If any Agent Member does not make such dividends available in
same-day funds to a Beneficial Owner, such Beneficial Owner who uses such Agent
Member would not have same-day funds available to it until the next Business
Day, which, in the case of a Dividend Payment Date that is a Wednesday, would be
the following Thursday if it is a Business Day.

     DETERMINATION OF DIVIDEND RATE.  The dividend rates on shares of Municipal
Preferred offered pursuant to the Prospectus during the period from and after
the Date of Original Issue thereof to and including the last day of the Initial
Rate Period therefor will be equal to the rate per annum set forth with respect
to such shares on the cover page of the Prospectus. For each Subsequent Rate
Period thereafter, the dividend rate on such shares will be equal to the rate
per annum that results from an Auction on the Auction Date next preceding such
Subsequent Rate Period; provided, however, if:

          (i) an Auction for any Subsequent Rate Period is not held for any
     reason other than as described below, the dividend rate on such shares for
     such Subsequent Rate Period will be the Maximum Rate on the Auction Date
     therefor;

          (ii) any Failure to Deposit shall have occurred with respect to shares
     of Municipal Preferred during any Rate Period thereof (other than any
     Special Rate Period of more than 364 Rate Period Days or any Rate Period
     succeeding any Special Rate Period of more than 364 Rate Period Days during
     which a Failure to Deposit occurred that has not been cured), but, prior to
     12:00 Noon, Eastern time, on the third Business Day next succeeding the
     date on which such Failure to Deposit occurred, such Failure to Deposit
     shall have been cured in accordance with the next succeeding paragraph and
     the Fund shall have paid to the Auction Agent a late charge ("Late Charge")
     equal to the sum of (1) if such Failure to Deposit consisted of the failure
     timely to pay to the Auction Agent the full amount of dividends with
     respect to any Dividend Period of such shares, an amount computed by
     multiplying (x) 200% of the Reference Rate for the Rate Period during which
     such Failure to Deposit occurs on the Dividend Payment Date for such
     Dividend Period by (y) a fraction, the numerator of which shall be the
     number of days for which such Failure to Deposit has not been cured in
     accordance with the next succeeding paragraph (including the day such
     Failure to Deposit occurs and excluding the day such Failure to Deposit is
     cured) and the denominator of which shall be 360, and applying the rate
     obtained against the aggregate Liquidation Preference of the outstanding
     shares of Municipal Preferred and (2) if such Failure to Deposit consisted
     of the failure timely to pay to the Auction Agent the Redemption Price of
     the shares of Municipal Preferred, if any, for which Notice of Redemption
     has been mailed by the Fund, an amount computed by multiplying (x) 200% of
     the Reference Rate for the Rate Period during which such Failure to Deposit
     occurs on the redemption date by (y) a fraction, the numerator of which
     shall be the number of days for which such Failure to Deposit is not cured
     in accordance with the next succeeding paragraph (including the day such
     Failure to Deposit occurs and excluding the day such Failure to Deposit is
     cured) and the denominator of which shall be 360, and applying the rate
     obtained against the aggregate Liquidation Preference of the outstanding
     shares of Municipal Preferred to be redeemed, no Auction will be held in
     respect of shares of Municipal Preferred for the Subsequent Rate Period
     thereof and the dividend rate for such Subsequent Rate Period will be the
     Maximum Rate on the Auction Date for such Subsequent Rate Period (but with

     determining such Maximum Rate, being deemed to be below Ba3/BB-);

          (iii) any Failure to Deposit shall have occurred with respect to
     shares of Municipal Preferred during any Rate Period thereof (other than
     any Special Rate Period of more than 364 Rate Period Days or any Rate
     Period succeeding any Special Rate Period of more than 364 Rate Period Days
     during which a Failure to Deposit occurred that has not been cured), and,
     prior to 12:00 Noon, Eastern time, on the third Business Day next
     succeeding the date on which such Failure to Deposit occurred, such Failure
     to Deposit shall not have been cured in accordance with the next succeeding
     paragraph or the Fund shall not have paid the applicable Late Charge to the
     Auction Agent, no Auction will be held in respect of Municipal Preferred
     for the first Subsequent Rate Period thereof thereafter (or for any Rate
     Period thereafter to and including the Rate Period during which (1) such
     Failure to Deposit is cured in accordance with the next succeeding
     paragraph and (2) the Fund pays the applicable Late Charge to the Auction
     Agent (the condition set forth in this clause (2) to apply only in the
     event Moody's is rating such shares at the time the Fund cures such Failure
     to Deposit), in each case no later than 12:00 Noon, Eastern time, on the
     fourth Business Day prior to the end of such Rate Period), and the dividend
     rate for shares of Municipal Preferred for each such Subsequent Rate Period
     will be a rate per annum equal to the Maximum Rate on the Auction Date for
     such Subsequent Rate Period (but with the prevailing rating for such
     shares, for purposes of determining such Maximum Rate, being deemed to be
     below Ba3/BB-); or

          (iv) any Failure to Deposit shall have occurred with respect to shares
     of Municipal Preferred during a Special Rate Period thereof of more than
     364 Rate Period Days, or during any Rate Period thereof succeeding any
     Special Rate Period of more than 364 Rate Period Days during which a
     Failure to Deposit occurred that has not been cured, and, prior to 12:00
     Noon, Eastern time, on the fourth Business Day preceding the Auction Date
     for the Rate Period subsequent to such Rate Period, such Failure to Deposit
     shall not have been cured in accordance with the next succeeding paragraph
     or, in the event Moody's is then rating such shares, the Fund shall not
     have paid the applicable Late Charge to the Auction Agent (such Late
     Charge, for purposes of this subparagraph (iv), to be calculated by using,
     as the Reference Rate, the Reference Rate applicable to a Rate Period (x)
     consisting of more than 182 Rate Period Days but fewer than 365 Rate Period
     Days and (y) commencing on the date on which the Rate Period during which
     Failure to Deposit occurs commenced), no Auction will be held in respect of
     shares of Municipal Preferred for such Subsequent Rate Period (or for any
     Rate Period thereafter to and including the Rate Period during which (1)
     such Failure to Deposit is cured in accordance with the next succeeding
     paragraph and (2) the Fund pays the applicable Late Charge to the Auction
     Agent (the condition set forth in this clause (2) to apply only in the
     event Moody's is rating such shares at the time the Fund cures such Failure
     to Deposit), in each case no later than 12:00 Noon, Eastern time, on the
     fourth Business Day prior to the end of such Rate Period), and the dividend
     rate for shares of Municipal Preferred for each such Subsequent Rate Period
     shall be a rate per annum equal to the Maximum Rate on the Auction Date for
     such Subsequent Rate Period (but with the prevailing rating for such
     shares, for purposes of determining such Maximum Rate, being deemed to be
     below Ba3/BB-) (the rate per annum at which dividends are payable on shares
     of Municipal Preferred for any Rate Period being herein referred to as the
     "Applicable Rate" for such shares).

     A Failure to Deposit with respect to shares of Municipal Preferred shall
have been cured (if such Failure to Deposit is not solely due to the willful
failure of the Fund to make the required payment to the Auction Agent) with
respect to any Rate Period if, within the respective time periods described
immediately above, the Fund shall have paid to the Auction Agent (i) all
accumulated and unpaid dividends on the shares of Municipal Preferred and (ii)
without duplication, the Redemption Price for the shares of Municipal Preferred,
if any, for which Notice of Redemption has been mailed; provided, however, that
the foregoing clause (ii) shall not apply to the Fund's failure to pay the
Redemption Price in respect of shares of Municipal Preferred when the related
Notice of Redemption provides that redemption of such shares is subject to one
or more conditions precedent and any such condition precedent shall not have
been satisfied at the time or times and in the manner specified in such Notice
of Redemption.

                                       30
<PAGE>   78

     The Fund shall pay to the Auction Agent, not later than 12:00 Noon, Eastern
time, on the Business Day next preceding each Dividend Payment Date for shares
of Municipal Preferred, an aggregate amount of funds available on the next
Business Day in the City of New York, New York equal to the dividends to be paid
to all Holders of such shares on such Dividend Payment Date. All moneys paid to
the Auction Agent for the payment of dividends (or for payment of any Late
Charge) shall be held in trust for the payment of such dividends (and any such
Late Charge) by the Auction Agent for the benefit of the Holders specified
above. Any moneys paid to the Auction Agent in accordance with the foregoing but
not applied by the Auction Agent to the payment of dividends (and any such Late
Charge) will, to the extent permitted by law, be repaid to the Fund at the end
of 90 days from the date on which such moneys were so to have been applied.

     GROSS-UP PAYMENTS.  Holders of shares of Municipal Preferred shall be
entitled to receive, when, as and if declared by the Board of Trustees, out of
funds legally available therefor in accordance with the Declaration, the
Certificate and applicable law, dividends in an amount equal to the aggregate
Gross-up Payment in accordance with the following:

     If, in the case of any Minimum Rate Period or any Special Rate Period of 28
Rate Period Days or fewer, the Fund allocates any net capital gain or other
income taxable for Federal income tax purposes to a dividend paid on shares of
Municipal Preferred without having given advance notice thereof to the Auction
Agent as described above under "The Auction -- Auction Dates; Advance Notice of
Allocation of Taxable Income" (such allocation is referred to herein as a
"Taxable Allocation") solely by reason of the fact that such allocation is made
retroactively as a result of the redemption of all or a portion of the
outstanding shares of Municipal Preferred or the liquidation of the Fund, the
Fund will, prior to the end of the calendar year in which such dividend was
paid, provide notice thereof to the Auction Agent and direct the Fund's dividend
disbursing agent to send such notice with a Gross-up Payment to each holder of
shares (initially Cede & Co., as nominee of the Securities Depository) that was
entitled to such dividend payment during such calendar year at such Holder's
address as the same appears or last appeared on the record books of the Fund.

     If, in the case of any Special Rate Period of more than 28 Rate Period
Days, the Fund makes a Taxable Allocation to a dividend paid on shares of
Municipal Preferred, the Fund shall, prior to the end of the calendar year in
which such dividend was paid, provide notice thereof to the Auction Agent and
direct the Fund's dividend disbursing agent to send such notice with a Gross-up
Payment to each Holder of shares that was entitled to such dividend payment
during such calendar year at such Holder's address as the same appears or last
appeared on the record books of the Fund.

     The Fund shall not be required to make Gross-up Payments with respect to
any net capital gains or other taxable income determined by the Internal Revenue
Service to be allocable in a manner different from that allocated by the Fund.

     A "Gross-up Payment" in respect of any dividend means payment to a holder
of shares of Municipal Preferred of an amount which, giving effect to the
Taxable Allocations made with respect to such dividend, would cause such
Holder's after-tax returns (taking into account both the Taxable Allocations and
the Gross-up Payment) to be equal to the after-tax return the holder would have
received if no such Taxable Allocations had occurred. Such Gross-up Payment
shall be calculated: (i) without consideration being given to the time value of
money; (ii) assuming that no holder of shares of Municipal Preferred is subject
to the Federal alternative minimum tax with respect to dividends received from
the Fund; and (iii) assuming that each holder of shares of Municipal Preferred
is taxable at the maximum marginal regular Federal individual income tax rate
applicable to ordinary income or net capital gain, as applicable, or the maximum
marginal regular Federal corporate income tax rate applicable to ordinary income
or net capital gain, as applicable, whichever is greater, in effect at the time
such Gross-up Payment is made.

     RESTRICTIONS ON DIVIDENDS AND OTHER PAYMENTS.  Under the 1940 Act, the
Board of Trustees may not declare any dividend (except a dividend payable in
Common Shares), or declare any other distribution, upon Common Shares, or
purchase Common Shares, unless in every such case the Preferred Shares,
including the shares of Municipal Preferred, have, at the time of any such
declaration or purchase (and
                                       31
<PAGE>   79

after giving effect thereto), an asset coverage (as defined in and determined
pursuant to the 1940 Act) of at least 200% (or such other asset coverage as may
in the future be specified in or under the 1940 Act as the minimum asset
coverage for senior securities which are shares or stock of a closed-end
investment company as a condition of declaring dividends on its common shares or
stock) after deducting the amount of such dividend, distribution or purchase
price, as the case may be.

     In addition, for so long as any shares of Municipal Preferred are
outstanding, except as set forth in the following paragraph or otherwise
described herein, (A) the Fund may not declare, pay or set apart for payment any
dividend or other distribution (other than a dividend or distribution paid in
shares of, or in options, warrants or rights to subscribe for or purchase,
Common Shares or other shares, if any, ranking junior to the shares of Municipal
Preferred as to the payment of dividends and the distribution of assets upon
dissolution, liquidation or winding up) in respect of Common Shares or any other
shares of the Fund ranking junior to or on a parity with the shares of Municipal
Preferred as to the payment of dividends or the distribution of assets upon
dissolution, liquidation or winding up, 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 the shares of Municipal Preferred as to the payment of
dividends and the distribution of assets upon dissolution, liquidation or
winding up), or any such parity shares (except by conversion into or exchange
for shares of the Fund ranking junior to or on a parity with the shares of
Municipal Preferred as to payment of dividends and the distribution of assets
upon dissolution, liquidation or winding up), unless (1) full cumulative
dividends on shares of Municipal Preferred through its most recently ended
Dividend Period shall have been paid or shall have been declared and sufficient
funds for the payment thereof deposited with the Auction Agent and (2) the Fund
has redeemed the full number of shares of Municipal Preferred required to be
redeemed by any provision for mandatory redemption pertaining thereto, and (B)
if either Moody's or S&P is rating the shares of Municipal Preferred, the Fund
may not declare, pay or set apart for payment any dividend or other distribution
(other than a dividend or distribution paid in shares of, or in options,
warrants or rights to subscribe for or purchase, Common Shares or other shares,
if any, ranking junior to shares of Municipal Preferred as to the payment of
dividends and the distribution of assets upon dissolution, liquidation or
winding up) in respect of Common Shares or any other shares of the Fund ranking
junior to shares of Municipal Preferred as to the payment of dividends or the
distribution of assets upon dissolution, liquidation or winding up, 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 the shares of Municipal Preferred as to
the payment of dividends or the distribution of assets upon dissolution,
liquidation or winding up), unless immediately after such transaction the
Discounted Value of Moody's Eligible Assets or S&P Eligible Assets, or both, as
the case may be, would at least equal the Municipal Preferred Basic Maintenance
Amount (see "-- Rating Agency Guidelines" and "-- Redemption").

     Except as set forth in the next sentence, no dividends shall be declared or
paid or set apart for payment on any class or series of shares of beneficial
interest of the Fund ranking, as to the payment of dividends, on a parity with
shares of Municipal Preferred for any period unless full cumulative dividends
have been or contemporaneously are declared and paid on the shares of Municipal
Preferred through their most recent Dividend Payment Date. When dividends are
not paid in full upon the shares of Municipal Preferred through their most
recent Dividend Payment Date or upon any other class or series of shares ranking
on a parity as to the payment of dividends with shares of Municipal Preferred
through their most recent respective dividend payment dates, all dividends
declared upon shares of Municipal Preferred and any other such class or series
of shares ranking on a parity as to the payment of dividends with shares of
Municipal Preferred shall be declared pro rata so that the amount of dividends
declared per share on shares of Municipal Preferred and such other class or
series of shares shall in all cases bear to each other the same ratio that
accumulated dividends per share on the shares of Municipal Preferred and such
other class or series of shares bear to each other (for purposes of this
sentence, the amount of dividends declared per share of Municipal Preferred
shall be based on the Applicable Rate for such share for the Dividend Periods
during which dividends were not paid in full).

                                       32

     Under the Code, the Fund must, among other things, distribute at least 90%
of the sum of its net investment income (including the excess, if any, of net
short-term capital gain over net long-term capital loss) and its net tax-exempt
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 may under certain circumstances impair the Fund's
ability to maintain such qualification.

     DESIGNATION OF SPECIAL RATE PERIODS.  The Fund, at its option, may
designate any succeeding Subsequent Rate Period of shares of Municipal Preferred
as a Special Rate Period consisting of a specified number of Rate Period Days
evenly divisible by seven and not more than 1,820 (approximately 5 years),
subject to adjustment as described below. A designation of a Special Rate Period
shall be effective only if (i) notice thereof shall have been given as provided
herein, (ii) an Auction for such shares shall have been held on the Auction Date
immediately preceding the first day of such proposed Special Rate Period and
Sufficient Clearing Bids for such shares shall have existed in such Auction and
(iii) if the Fund shall have mailed a Notice of Redemption with respect to any
shares of Municipal Preferred, as described under "-- Redemption -- Notice of
Redemption" below, the Redemption Price with respect to such shares shall have
been deposited with the Auction Agent. In the event the Fund wishes to designate
any succeeding Subsequent Rate Period for shares of Municipal Preferred as a
Special Rate Period consisting of more than 28 Rate Period Days, the Fund shall
notify S&P (if S&P is then rating such shares) and Moody's (if Moody's is then
rating such shares) in advance of the commencement of such Subsequent Rate
Period that the Fund wishes to designate such Subsequent Rate Period as a
Special Rate Period and shall provide S&P (if S&P is then rating such shares)
and Moody's (if Moody's is then rating such shares) with such documents as
either may reasonably request.

     In the event the Fund wishes to designate a Subsequent Rate Period as a
Special Rate Period, but the day following what would otherwise be the last day
of such a Special Rate Period is not a Wednesday that is a Business Day in the
case of shares of Series T Municipal Preferred, then the Fund shall designate
such Subsequent Rate Period as a Special Rate Period consisting of the period
commencing on the first day following the end of the immediately preceding Rate
Period and ending on the first Tuesday that is followed by a Wednesday that is a
Business Day preceding what would otherwise be such last day, in the case of
Series T Municipal Preferred.

     If the Fund proposes to designate any succeeding Subsequent Rate Period of
shares of Municipal Preferred as a Special Rate Period, not less than 20 (or
such lesser number of days as may be agreed to from time to time by the Auction
Agent) nor more than 30 days prior to the date the Fund proposes to designate as
the first day of such Special Rate Period (which shall be such day that would
otherwise be the first day of a Minimum Rate Period), notice shall be (i)
published or caused to be published by the Fund in a newspaper of general
circulation to the financial community in The City of New York, New York, which
carries financial news, and (ii) mailed by the Fund by first-class mail, postage
prepaid, to the Holders of shares of Municipal Preferred. Each such notice shall
state (A) that the Fund may exercise its option to designate a succeeding
Subsequent Rate Period of shares of Municipal Preferred as a Special Rate
Period, specifying the first day thereof and (B) that the Fund will, by 11:00
A.M., Eastern time, on the second Business Day next preceding such date (or by
such later time or date, or both, as may be agreed to by the Auction Agent),
notify the Auction Agent of either (x) its determination, subject to certain
conditions, to exercise such option, in which case the Fund shall specify the
Special Rate Period designated, or (y) its determination not to exercise such
option.

     No later than 11:00 A.M., Eastern time, on the second Business Day next
preceding the first day of any proposed Special Rate Period as to which notice
has been given as set forth in the preceding paragraph (or such later time or
date, or both, as may be agreed to by the Auction Agent), the Fund shall deliver
to the Auction Agent either:

          (i) a notice ("Notice of Special Rate Period") stating (A) that the
     Fund has determined to designate the next succeeding Rate Period of shares
     of Municipal Preferred as a Special Rate Period, specifying the same and
     the first day thereof, (B) the Auction Date immediately prior to the first
     day of such Special Rate Period, (C) that such Special Rate Period shall
     not commence if (1) an

                                       33
<PAGE>   81

     Auction for such shares shall not be held on such Auction Date for any
     reason or (2) an Auction for such shares shall be held on such Auction Date
     but Sufficient Clearing Bids for such shares shall not exist in such
     Auction, (D) the scheduled Dividend Payment Dates for such shares during
     such Special Rate Period and (E) the Special Redemption Provisions, if any,
     applicable to such shares in respect of such Special Rate Period; such
     notice to be accompanied by a Municipal Preferred Basic Maintenance Report
     showing that, as of the third Business Day next preceding such proposed
     Special Rate Period, Moody's Eligible Assets (if Moody's is then rating
     such shares) and S&P Eligible Assets (if S&P is then rating such shares)
     each have an aggregate Discounted Value at least equal to the Municipal
     Preferred Basic Maintenance Amount as of such Business Day (assuming for
     purposes of the foregoing calculation that (a) the Maximum Rate is the
     Maximum Rate on such Business Day as if such Business Day were the Auction
     Date for the proposed Special Rate Period, and (b) the Moody's Discount
     Factors applicable to Moody's Eligible Assets will be determined by
     reference to the first Moody's Exposure Period longer than the Moody's
     Exposure Period then applicable to the Fund); or

          (ii) a notice stating that the Fund has determined not to exercise its
     option to designate a Special Rate Period of shares of Municipal Preferred
     and that the next succeeding Rate Period shall be a Minimum Rate Period.

     If the Fund fails to deliver either such notice (and, in the case of the
notice described in clause (i) above, a Municipal Preferred Basic Maintenance
Report to the effect set forth in clause (i) (if either Moody's or S&P is then
rating the shares of Municipal Preferred)) with respect to any designation of
any proposed Special Rate Period to the Auction Agent by 11:00 A.M., Eastern
time, on the second Business Day next preceding the first day of such proposed
Special Rate Period (or by such later time or date, or both, as may be agreed to
by the Auction Agent), the Fund shall be deemed to have delivered a notice to
the Auction Agent with respect to such Special Rate Period to the effect set
forth in clause (ii) above. In the event the Fund delivers to the Auction Agent
a notice described in clause (i) above, it shall file a copy of such notice with
the Secretary of the Fund, and the contents of such notice shall be binding on
the Fund. In the event the Fund delivers to the Auction Agent a notice described
in clause (ii) above, the Fund will provide Moody's (if Moody's is then rating
the shares of Municipal Preferred) and S&P (if S&P is then rating the shares of
Municipal Preferred) a copy of such notice.

VOTING RIGHTS

     Holders of shares of Municipal Preferred are entitled to vote on certain
matters as described herein under "Investment Restrictions," in the Prospectus
under "Description of Municipal Preferred -- Voting Rights" and in Section 5 of
Part I of the Certificate.

     In connection with the election of the Fund's Trustees, holders of
outstanding Preferred Shares, including shares of Municipal Preferred, voting
together as one separate class, shall be entitled to elect two of the Fund's
Trustees, and the remaining Trustees will be elected by holders of Common Shares
and Preferred Shares, including shares of Municipal Preferred, voting together
as a single class. In addition, if at any time dividends (whether or not earned
or declared) on outstanding Preferred Shares, including shares of Municipal
Preferred, shall be due and unpaid in an amount equal to two full years'
dividends thereon, and sufficient cash or specified securities shall not have
been deposited with the Auction Agent for the payment of such dividends, then,
as the sole remedy of holders of outstanding Preferred Shares, including shares
of Municipal Preferred, 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, including shares of Municipal Preferred, 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 Preferred Shares, including shares of Municipal
Preferred, 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 will be in any event entitled to elect, constitutes a majority of the
total number of Trustees of the Fund as so increased. The terms of office of
                                       34
<PAGE>   82

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 Preferred Shares, including shares of
Municipal Preferred, the voting rights stated in the preceding sentence shall
cease, and the terms of office of all of the additional Trustees elected by the
holders of Preferred Shares, including shares of Municipal Preferred (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 Preferred Shares have the
right to elect in any event), will terminate automatically.

     So long as any shares of Municipal Preferred are outstanding, the Fund may
not, without the affirmative vote of the Holders of at least a majority of the
shares of Municipal Preferred outstanding at the time, voting together as one
separate class:

          (a) authorize, create or issue additional shares of Municipal
     Preferred or classes or series of Preferred Shares ranking prior to or on a
     parity with shares of Municipal Preferred with respect to the payment of
     dividends or the distribution of assets upon dissolution, liquidation or
     winding up of the affairs of the Fund (except that the Fund may, without
     the vote of the Holders of shares of Municipal Preferred, authorize, create
     or issue additional shares of Municipal Preferred or classes or series of
     Preferred Shares ranking on a parity with shares of Municipal Preferred
     with respect to the payment of dividends and the distribution of assets
     upon dissolution, liquidation or winding up of the affairs of the Fund;
     provided, however, that if Moody's or S&P is not then rating the shares of
     Municipal Preferred the aggregate liquidation preference of all Preferred
     Shares of the Fund outstanding after such issuance, exclusive of
     accumulated and unpaid dividends, may not exceed $70,000,000; provided,
     however that (i) the Fund obtains written confirmation from Moody's (if
     Moody's is then rating the shares of Municipal Preferred) and S&P (if S&P
     is then rating the shares of Municipal Preferred) that the issuance of any
     additional shares or class or series of shares would not impair the rating
     then assigned by such rating agency to shares of Municipal Preferred, and
     (ii) so long as either at least one of Moody's or S&P is rating the shares
     of Municipal Preferred, the Fund may, without the vote of the Holders of
     the shares of Municipal Preferred, authorize, create or issue additional
     shares of Municipal Preferred or classes or series of Preferred Shares
     ranking on parity with the shares of Municipal Preferred with respect to
     the payment of dividends and the distribution of assets upon dissolution,
     liquidation or winding up of the affairs of the Fund notwithstanding that,
     after giving effect thereto, the aggregate liquidation preference of all
     Preferred Shares then outstanding would exceed $70,000,000; or


          (b) amend, alter or repeal the provisions of the Certificate,
     Declaration of Trust or By-laws, whether by merger, consolidation or
     otherwise, so as to affect any preference, right or power of the shares of
     Municipal Preferred or the Holders thereof; provided, however, that (i)
     none of the actions permitted by the exception to (a) above will be deemed
     to affect such preferences, rights or powers, (ii) a division of a share of
     Municipal Preferred will be deemed to affect such preferences, rights or
     powers only if the terms of such division adversely affect the Holders of
     shares of Municipal Preferred and (iii) the authorization, creation and
     issuance of classes or series of shares ranking junior to shares of
     Municipal Preferred with respect to the payment of dividends and the
     distribution of assets upon dissolution, liquidation or winding up of the
     affairs of the Fund will be deemed to affect such preferences, rights or
     powers only if Moody's or S&P is then rating the shares of Municipal
     Preferred and such issuance would, at the time thereof, cause the Fund not
     to satisfy the 1940 Act Municipal Preferred Asset Coverage or the Municipal
     Preferred Basic Maintenance Amount. So long as any shares of Municipal
     Preferred are outstanding, the Fund may not, without the affirmative vote
     of the Holders of at least 66 2/3% of the shares of Municipal Preferred
     outstanding at the time, in person or by proxy, either in writing or at a
     meeting, voting as a separate class, 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. If any action would adversely affect the rights of one or more
     series (the "Affected Series") of Municipal Preferred in a manner different
     from any other series of Municipal Preferred, the Fund will not approve any
     such action without the affirmative vote of the Holders of at least a
     majority of the shares of each such Affected Series outstanding at


                                       35
<PAGE>   83

     the time, in person or by proxy, either in writing or at a meeting (each
     such Affected Series voting as a separate class).

     Voting provisions will not apply with respect to shares of Municipal
Preferred if, at or prior to the time when a vote is required, 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 Board of Trustees may, without shareholder approval, amend, alter or
repeal any or all of the definitions and related provisions required to be
contained in the Certificate or Declaration of Trust by the rating agencies in
the event the Fund receives written confirmation from Moody's or S&P, or both,
as appropriate, that any such amendment, alteration or repeal would not impair
the ratings then assigned by Moody's or S&P, as the case may be, to shares of
Municipal Preferred.


RATING AGENCY GUIDELINES


     The Fund intends that, so long as shares of Municipal Preferred are
outstanding, the composition of its portfolio will reflect guidelines
established by either Moody's or S&P in connection with the Fund's receipt on
the Date of Original Issue of the shares of Municipal Preferred of ratings of
aaa from Moody's or AAA from S&P. Moody's and S&P, nationally recognized
independent rating agencies, issue ratings for various securities reflecting
their perceived creditworthiness of such securities. The guidelines described
below have been developed by Moody's and S&P in connection with other issuances
of similar securities, including debt obligations and adjustable rate preferred
shares, generally on a case-by-case basis through discussions with the issuers
of those securities. The guidelines are designed to ensure that assets
underlying outstanding debt or preferred shares will be sufficiently varied 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 or S&P, or both,
to issue the above-described ratings for shares of Municipal Preferred, which
ratings are generally relied upon by investors in purchasing such securities. In
the context of a closed-end investment company such as the Fund, therefore, 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. A rating agency's guidelines will apply to
shares of Municipal Preferred only so long as such rating agency is rating such
shares. The Board of Trustees may, without shareholder approval, amend, alter or
repeal any or all of the definitions and related provisions which have been
adopted by the Fund pursuant to the rating agency guidelines in the event the
Fund receives written confirmation from Moody's or S&P, or both, as appropriate,
that any such change would not impair the ratings then assigned by Moody's or
S&P, as the case may be, to shares of Municipal Preferred.


     For so long as any shares of Municipal Preferred are outstanding and
Moody's or S&P, or both, are rating such shares, the Fund will not, unless it
has received written confirmation from Moody's or S&P, or both, as appropriate,
that any action would not impair the ratings then assigned by such rating agency
to such shares, engage in any one or more of the following transactions (as
outlined in the next paragraph): (1) futures or options transactions, except in
accordance with the then-current guidelines of such rating agencies, (2) borrow
money, except that the Fund may, without obtaining the written confirmation
described above, borrow money for the purpose of clearing securities
transactions if (i) the Municipal Preferred Basic Maintenance Amount would
continue to be satisfied after giving effect to such borrowing and (ii) such
borrowing (A) is privately arranged with a bank or other person and is evidenced
by a promissory note or other evidence of indebtedness that is not intended to
be publicly distributed or (B) is for "temporary purposes," is evidenced by a
promissory note or other evidence of indebtedness and is an amount not exceeding
5 per centum of the value of the total assets of the Fund at the time of the
borrowing; for purposes of the foregoing, "temporary purpose" means that the
borrowing is to be repaid within sixty days and is not be extended or renewed,
(3) issue additional shares of Municipal Preferred or any class or series of
shares ranking prior to shares of Municipal Preferred with respect to the
payment of dividends or the distribution of assets upon dissolution, liquidation
or winding up of the affairs of the Fund, or reissue any shares of Municipal
Preferred previously purchased or redeemed by the Fund, (4) engage in any short
sales of securities, (5) lend securities, (6) merge or consolidate into or with
any corporation,
                                       36
<PAGE>   84

(7) use a Pricing Service not approved by S&P or Moody's, or both, as applicable
or (8) enter into reverse repurchase agreements. While the Fund does not
presently intend to borrow, and while the Fund is restricted under the 1940 Act
from borrowing in excess of 33 1/3% of its total assets and is otherwise
restricted from borrowing pursuant to rating agency guidelines, under certain
circumstances and notwithstanding adverse interest rate or market conditions,
the Fund is permitted to borrow for temporary or emergency purposes (e.g., to
make required distributions or pay dividends) or to repurchase shares when such
borrowing is deemed to be in the best interest of the common shareholders. See
"Repurchase of Common Shares" herein and "Description of Capital
Structure -- Repurchase of Common Shares" in the Prospectus for the
circumstances under which the Fund may purchase Common Shares and incur
indebtedness in connection therewith. Should the Fund borrow, the Fund would be
required to pay when due the interest obligation on any debt incurred by the
Fund before it would be able to pay dividends on shares of Municipal Preferred,
and it is likely that the Fund would be required to pay the principal amount of
any such debt prior to meeting the liquidation preference of the shares of
Municipal Preferred. Because the interest expense on borrowings by the Fund will
reduce the Fund's net investment earnings available to pay dividends on shares
of Municipal Preferred, borrowing may impair the Fund's ability to pay such
dividends on shares of Municipal Preferred. This risk is heightened in the event
the Fund incurs variable rate debt, the interest rate on which may increase with
increases in prevailing market rates.

     The Fund may 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,
except that the Fund may purchase or sell futures contracts based upon the Bond
Buyer Municipal Bond Index (the "Municipal Index") or the United States Treasury
Bonds or Notes ("Treasury Bonds") and write, purchase or sell put and call
options on such contracts (collectively, "Hedging Transactions"), subject to the
following limitations: (A) the Fund will not engage in any Hedging Transaction
based on the Municipal Index (other than transactions which terminate a futures
contract or option held by the Fund by the Fund's taking an opposite position
thereto ("Closing Transactions")), which would cause the Fund at the time of
such transaction to own or have sold the least of (i) more than 1,000
outstanding futures contracts based upon the Municipal Index, (ii) outstanding
futures contracts based on the Municipal Index exceeding in number 25% of the
quotient of the Market Value of the Fund's total assets divided by $1,000 or
(iii) 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 transactions
as reported by The Wall Street Journal; (B) the Fund will not engage in any
Hedging Transaction based on Treasury Bonds (other than Closing Transactions)
which would cause the Fund at the time of such transaction to own or have sold
the lesser of (i) outstanding futures contracts based on Treasury Bonds
exceeding in number 50% of the quotient of the 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 (ii) outstanding futures contracts based on Treasury Bonds
exceeding in number 10% of the average number of daily traded futures contracts
based on Treasury Bonds in the 30 days preceding the time of effecting such
transaction as reported by The Wall Street Journal; (C) the Fund will engage in
Closing Transactions to close out any outstanding futures contracts which the
Fund owns or has sold or any outstanding option thereon owned by the Fund in the
event (i) the Fund does not have S&P Eligible Assets or Moody's Eligible Assets,
as the case may be, with an aggregate Discounted Value equal or greater than the
Municipal Preferred Basic Maintenance Amount on two consecutive Valuation Dates
and (ii) the Fund is required to pay additional margin due to fluctuation in
contract price ("Variation Margin") on the second such Valuation Date; (D) the
Fund 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 Fund hold the
securities deliverable under such terms; and (E) when the Fund 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 or Moody's, as the case
may be), fixed-income securities in a segregated account with the Fund's
custodian, so that the amount so segregated plus the amount of margin paid on
such contract ("Initial Margin") and any Variation Margin held in the account of
or on behalf of the Fund's broker with respect to such futures contract or
option equals the Market Value of the futures contract or option,

                                       37
<PAGE>   85

or, in the event the Fund 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 Fund has S&P Eligible Assets or
Moody's Eligible Assets, as the case may be, with a Discounted Value that equals
or exceeds the Municipal Preferred Basic Maintenance Amount, the Discounted
Value of cash or securities held for payment of Initial Margin or Variation
Margin shall be zero and the aggregate Discounted Value of S&P Eligible Assets
or Moody's Eligible Assets, as the case may be, 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 Fund 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 Fund.

ASSET MAINTENANCE

     1940 ACT MUNICIPAL PREFERRED ASSET COVERAGE.  The Fund will be required
under rating agency guidelines to maintain, as of the last Business Day of each
month on which any shares of Municipal Preferred are outstanding, asset coverage
of at least 200% with respect to such shares (or such other asset coverage as
may in the future be specified in or under the 1940 Act as the minimum asset
coverage for senior securities which are shares of a closed-end investment
company as a condition of declaring dividends on its common shares). If the Fund
fails to maintain such asset coverage in accordance with the requirements of the
rating agency or agencies then rating the shares of Municipal Preferred ("1940
Act Municipal Preferred Asset Coverage") and such failure is not cured as of the
last Business Day of the following month (the "1940 Act Cure Date"), the Fund
will be required under certain circumstances to redeem certain of the shares of
Municipal Preferred. See "-- Redemption" below.

     MUNICIPAL PREFERRED BASIC MAINTENANCE AMOUNT.  The Fund will be required
under rating agency guidelines to maintain, as of each Business Day (a
"Valuation Date") on which shares of Municipal Preferred are outstanding, assets
having in the aggregate a Discounted Value at least equal to the Municipal
Preferred Basic Maintenance Amount established by the rating agency or agencies
then rating the shares of Municipal Preferred. If the Fund fails to meet such
requirement on any Valuation Date and such failure is not cured on or before the
seventh Business Day after such Valuation Date (the "Municipal Preferred Basic
Maintenance Cure Date"), the Fund will be required under certain circumstances
to redeem certain of the shares of Municipal Preferred. See "-- Redemption"
below.

     The "Municipal Preferred Basic Maintenance Amount" as of any Valuation Date
is defined as the dollar amount equal to the sum of:

          (A) (i) the product of the number of shares of Municipal Preferred
     outstanding on such date multiplied by $25,000 (plus the product of the
     number of shares of any other series of Preferred Shares outstanding on
     such date multiplied by the liquidation preference of such shares), plus
     any redemption premium applicable to shares of Municipal Preferred (or
     other Preferred Shares) then subject to redemption;

             (ii) the aggregate amount of dividends that will have accumulated
        at the respective Applicable Rates (whether or not earned or declared)
        to (but not including) the first respective Dividend Payment Dates for
        shares of Municipal Preferred outstanding that follow such Valuation
        Date (plus the aggregate amount of dividends, whether or not earned or
        declared, that will have accumulated in respect of other outstanding
        Preferred Shares to, but not including, the first respective dividend
        payment dates for such other shares that follow such Valuation Date);

             (iii) the aggregate amount of dividends that would accumulate on
        shares of Municipal Preferred outstanding from such first Dividend
        Payment Date through the 49th day after such Valuation Date, at the
        Maximum Rate (calculated as if such Valuation Date were the Auction Date
        for the Rate Period commencing on such Dividend Payment Date) for a
        Minimum Rate Period of shares of such series to commence on such
        Dividend Payment Date, assuming solely for purposes of the foregoing,
        that if on such Valuation Date the Fund shall have

                                       38
<PAGE>   86

        delivered a Notice of Special Rate Period to the Auction Agent with
        respect to shares of such series, such Maximum Rate shall be the higher
        of (a) the Maximum Rate for the Special Rate Period of such shares to
        commence on such Dividend Payment Date and (b) the Maximum Rate for a
        Minimum Rate Period of shares of such series to commence on such
        Dividend Payment Date, multiplied by the larger of the Moody's
        Volatility Factor and the S&P Volatility Factor applicable to a Minimum
        Rate Period, or, in the event the Fund shall have delivered a Notice of
        Special Rate Period to the Auction Agent with respect to shares of such
        series designating a Special Rate Period consisting of 49 Rate Period
        Days or more, the larger of the Moody's Volatility Factor and the S&P
        Volatility Factor applicable to a Special Rate Period of that length
        (plus the aggregate amount of dividends that would accumulate at the
        maximum dividend rate or rates on any other Preferred Shares outstanding
        from such respective dividend payment rates through the 49th day after
        such Valuation Date, as established by or pursuant to the respective
        statements establishing and fixing the rights and preferences of such
        other Preferred Shares) (except that (1) of such Valuation Date occurs
        at a time when a Failure to Deposit (or, in the case of Preferred Shares
        other than Municipal Preferred, a failure similar to a Failure to
        Deposit) has occurred that has not been cured, the dividend for purposes
        of calculation would accumulate at the current dividend rate then
        applicable to the shares in respect of which failure has occurred and
        (2) for those days during the period described in this subparagraph
        (iii) in respect of which the Applicable Rate in effect immediately
        prior to such Dividend Payment Date will remain in effect (or, in the
        case of the Preferred Shares other than Municipal Preferred, in respect
        of which the dividend rate or rates in effect immediately prior to such
        respective dividend payment dates will remain in effect) the dividend
        for purposes of calculation would accumulate at such Applicable Rate (or
        other rate or rates, as the case may be) in respect of those days);

             (iv) the amount of anticipated Fund expenses for the 90 days
        subsequent to such Valuation Date;

             (v) the amount of the Fund's Maximum Potential Gross-up Payment
        Liability as of such Valuation Date; and

             (vi) any current liabilities as of such Valuation Date to the
        extent not reflected in any of (A)(i) through (A)(v) (including, without
        limitation, any payables for Municipal Securities purchased as of such
        Valuation Date and any liabilities incurred for the purpose of clearing
        securities transactions) less

          (B) the value of any Fund assets irrevocably deposited by the Fund for
     the payment of any of (A)(i) through (A)(vi), all as calculated in
     accordance with the requirements of the rating agency or agencies then
     rating the shares of Municipal Preferred.

For purposes of the foregoing, "Maximum Potential Gross-up Payment Liability,"
as of any Valuation Date, means the aggregate amount of Gross-up Payments that
would be due if the Fund were to make Taxable Allocations, with respect to any
taxable year, estimated based upon dividends paid and the amount of
undistributed realized net capital gain and other taxable income earned by the
Fund, as of the end of the calendar month immediately preceding such Valuation
Date, and assuming such Gross-up Payments are fully taxable.

     In managing the Fund's portfolio, the Adviser will not alter the
composition of the Fund's portfolio if, in the reasonable belief of the Adviser,
the effect of any such alteration would be to cause the Fund to have Eligible
Assets with an aggregate Discounted Value, as of the Business Day immediately
preceding Valuation Date, less than the Municipal Preferred Basic Maintenance
Amount as of such Valuation Date; provided, however, that in the event that, as
of the Business Day immediately preceding Valuation Date, the aggregate
Discounted Value of the Fund's Eligible Assets exceeded the Municipal Preferred
Basic Maintenance Amount by 5% or less, the Adviser will not alter the
composition of the Fund's portfolio in a manner reasonably expected to reduce
the aggregate Discounted Value of the Fund's Eligible Assets unless

                                       39
<PAGE>   87

the Fund shall have confirmed that, after giving effect to such alteration, the
aggregate Discounted Value of the Fund's Eligible Assets would exceed the
Municipal Preferred Basic Maintenance Amount.

     Upon any failure to maintain the required Discounted Value, the Fund will
seek to alter the composition of its portfolio to reattain the Municipal
Preferred Basic Maintenance Amount on or prior to the Municipal Preferred Basic
Maintenance Cure Date, thereby incurring additional transaction costs and
possible losses and/or gains on dispositions of portfolio securities.

     On or before 5:00 P.M., Eastern time, on the third Business Day after a
Valuation Date on which the Fund fails to satisfy the Municipal Preferred Basic
Maintenance Amount, and on the third Business Day after the Municipal Preferred
Basic Maintenance Cure Date with respect to such Valuation Date, the Fund shall
complete and deliver to S&P (if S&P is then rating the shares of Municipal
Preferred), Moody's (if Moody's is then rating the shares of Municipal
Preferred) a Municipal Preferred Basic Maintenance Report as of the date of such
failure or such Municipal Preferred Basic Maintenance Cure Date, as the case may
be, which will be deemed to have been delivered to the Auction Agent if the
Auction Agent receives a copy of telecopy, telex or other electronic
transcription thereof and on the same day the Fund mails to the Auction Agent
for delivery on the next Business Day the full Municipal Preferred Basic
Maintenance Report. The Fund shall also deliver a Municipal Preferred Basic
Maintenance Report to (i) the Auction Agent (if either Moody's or S&P is then
rating the shares of Municipal Preferred as of (A) the fifteenth of each month
(or, if such day is not a Business Day, the next succeeding Business Day) and
(B) the last Business Day of each month, (ii) Moody's (if Moody's is then rating
the shares of Municipal Preferred) and S&P (if S&P is then rating the shares of
Municipal Preferred) as of any Quarterly Valuation Date, in each case on or
before the third Business Day after such day, and (iii) S&P, if and when
requested for any Valuation Date, on or before the third Business Day after such
request. A failure by the Fund to deliver a Municipal Preferred Basic
Maintenance Report pursuant to the preceding sentence shall be deemed to be
delivery of a Municipal Preferred Basic Maintenance Report indicating the
Discounted Value for all assets of the Fund is less than the Municipal Preferred
Basic Maintenance Amount, as of the relevant Valuation Date. Within ten Business
Days after delivery of such report relating to the last Business Day of each of
February, May, August and November of each year, commencing November 30, 1999,
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
Municipal Preferred Basic Maintenance Report. If any such letter prepared by the
Fund's independent accountants shows that an error was made in the most recent
Municipal Preferred Basic Maintenance Report, the calculation or determination
made by the Fund's independent accountants will be conclusive and binding on the
Fund.

     The Discount Factors and guidelines for determining the market value of the
Fund's portfolio holdings, described below, have been based by the rating
agencies on criteria such as 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. The ratings
may be changed, suspended or withdrawn as a result of changes in, or the
unavailability of, such information.

     S&P AAA RATING GUIDELINES.  For purposes of calculating the Discounted
Value of the Fund's portfolio under current S&P guidelines, the fair market
value of Municipal Securities eligible for consideration under such guidelines
("S&P Eligible Assets") must be discounted by certain discount factors set forth
in the table below ("S&P Discount Factors"). The Discounted Value of a Municipal
Security under S&P guidelines is the fair market value thereof divided by the
S&P Discount Factor. The S&P Discount Factor used to discount a particular
Municipal Security will be determined by reference to

                                       40
<PAGE>   88

the "S&P Exposure Period" (currently, ten Business Days) and the S&P rating on
such Municipal Security. S&P Discount Factors for a range of exposure periods
are set forth below:

 * S&P rating

** S&P Eligible Assets not rated by S&P or rated less than BBB by S&P or not
   rated at least the equivalent of an "A" rating by another recognized credit
   rating agency.

     Since the S&P Exposure Period currently applicable to the Fund is ten
Business Days, the S&P Discount Factors currently applicable to S&P Eligible
Assets will be determined by reference to the factors set forth opposite the
line entitled "10 Business Days." Notwithstanding the foregoing, (i) the S&P
Discount Factor for short-term Municipal Securities will be 115%, so long as
such Municipal Securities are rated A-1+ or SP-1+ by S&P and mature or have a
demand feature exercisable within 30 days or less, 120% if such Municipal
Securities are rated A-1 or SP-1 by S&P and mature or have a demand feature
exercisable within 30 days or less, or 125% if such Municipal Securities are not
rated by S&P but are rated VMIG-1, P-1 or MIG-1 by Moody's; provided, however,
that any such Moody's-rated short-term Municipal Securities which have demand
features exercisable within 30 days or less must be backed by a letter of
credit, liquidity facility or guarantee from a bank or other financial
institution with a short-term rating of at least A-1+ from S&P; and further
provided that such Moody's-rated short-term Municipal Securities may comprise no
more than 50% of short-term Municipal Securities that qualify as S&P Eligible
Assets; (ii) no S&P Discount Factor will be applied to cash, options, and
similar instruments or to Receivables for Municipal Securities Sold; and (iii)
except as set forth in clause (i) above, in the case of any Municipal Security
that is not rated by S&P but qualifies as a S&P Eligible Asset pursuant to
clause (1)(c) of the following paragraph, such Municipal Security will be deemed
to have a S&P rating one full rating category lower than the S&P rating category
that is the equivalent of the rating category in which such Municipal Security
is placed by such other nationally recognized credit rating agency. For purposes
of the foregoing, Anticipation Notes rated SP-1+ or, if not rated by S&P, rated
MIG-1 or VMIG-1 by Moody's, which do not mature or have a demand feature at par
exercisable in 30 days and which do not have a long-term rating, will be
considered to be short-term Municipal Securities. An S&P Discount Factor of 426%
will be applied to Municipal Securities rated AAA by S&P which are not interest
bearing or do not pay interest at least semi-annually. "Receivables for
Municipal Securities Sold," for purposes of calculating S&P Eligible Assets as
of any Valuation Date, means the book value of receivables for Municipal
Securities sold as of or prior to such Valuation Date if such receivables are
due within five business days of such Valuation Date.

     The S&P guidelines impose certain minimum issue size, issuer, geographical
diversification and other requirements for purposes of determining S&P Eligible
Assets:

          (1) In order to be considered S&P Eligible Assets, cash (excluding any
     cash irrevocably deposited by the Fund for payment of any liabilities
     within the meaning of Municipal Preferred Basic Maintenance Amount),
     Receivables for Municipal Securities Sold, futures, options, Inverse
     Floaters and similar instruments or a Municipal Security owned by the Fund
     shall:

             (a) be interest bearing and pay interest at least semi-annually;

             (b) be payable in U.S. dollars;

                                       41
<PAGE>   89

             (c) 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 another nationally
        recognized credit rating agency, be publicly rated A or higher by such
        agency;

             (d) not be subject to a covered call or covered put option written
        by the Fund;

             (e) except in the case of Inverse Floaters, not be part of a
        private placement of Municipal Securities; and

             (f) be part of an issue with an original issue size of at least $20
        million or, if of an issue with an original issue size below $20 million
        (but in no event lower than $10 million), be issued by an issuer with a
        total of at least $50 million of securities outstanding.

          (2) Municipal Securities (excluding Escrowed 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 Municipal
     Securities does not exceed 10% of the aggregate fair market value of 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 Municipal
     Securities exceeds 5% of the aggregate fair market value of S&P Eligible
     Assets, and provided that Municipal Securities (excluding Escrowed Bonds)
     not rated by S&P or rated less than BBB by S&P (or not rated at least "A"
     by another nationally recognized credit rating agency) of any one issuer or
     guarantor (excluding bond issuers) shall constitute S&P Eligible Assets
     only to the extent the Market Value of such Municipal Securities does not
     exceed 5% of the aggregate Market Value of S&P Eligible Assets.

          (3) Municipal Securities not rated at least BBB by S&P or not rated by
     S&P or not rated at least "A" by another nationally recognized credit
     rating agency shall be considered S&P Eligible Assets only to the extent
     the Market Value of such Municipal Securities, including unrated
     securities, does not exceed 50% of the aggregate Market Value of S&P
     Eligible Assets; provided however, that if the Market Value of such
     Municipal Securities exceeds 50% of the aggregate Market Value of S&P
     Eligible Assets, a portion of such Municipal Securities (selected by the
     Fund) shall not be considered S&P Eligible Assets, so that the Market Value
     of such Municipal Securities (excluding such portion) does not exceed 50%
     of the aggregate Market Value of S&P Eligible Assets.

          (4) Long-term Municipal Securities (excluding Escrowed Bonds) issued
     by issuers in any one state or territory will be considered S&P Eligible
     Assets only to the extent the fair market value of such Municipal
     Securities does not exceed 25% of the aggregate fair market value of S&P
     Eligible Assets.

          (5) Inverse Floaters shall be considered S&P Eligible Assets if the
     ratio of the aggregate dollar amount of floating rate instruments to
     inverse floating rate instruments issued by the same issuer does not exceed
     one to one at the time of original issuance. Leveraged floaters will
     qualify as S&P Eligible Assets if the floater has only one reset remaining
     before maturity.

          (6) Municipal Securities which are not interest bearing or do not pay
     interest at least semi-annually shall be considered S&P Eligible Assets if
     rated AAA by S&P.

     MOODY'S AAA RATING GUIDELINES.  For purposes of calculating the Discounted
Value of the Fund's portfolio under current Moody's guidelines, Municipal
Securities eligible for consideration under such guidelines ("Moody's Eligible
Assets") must be discounted by certain discount factors set forth in the table
below ("Moody's Discount Factors"). The Discounted Value of a Municipal
Obligation under Moody's guidelines is, as of any Valuation Date, (i) with
respect to a Moody's Eligible Asset that is not currently callable as of such
Valuation Date at the option of the issuer thereof, the quotient of the market
value thereof divided by the applicable Moody's Discount Factor, or (ii) with
respect to a Moody's Eligible Asset that is currently callable as of such
Valuation Date at the option of the issuer thereof, the quotient of (a) the
lesser of the market value or call price thereof, including any call premium,
divided by (b) the applicable Moody's Discount Factor. The Moody's Discount
Factor used to discount a particular

                                       42
<PAGE>   90

Municipal Obligation will be determined by reference to the "Moody's Exposure
Period" (currently, the period commencing on a given Valuation Date and ending
49 days thereafter) and the Moody's rating on such Municipal Obligation. Moody's
Discount Factors for a range of exposure periods for bonds with 10 years to
maturity are set forth below:

***  Municipal Securities rated MIG-1 or VMIG-1 or, if not rated by Moody's,
     rated SP-1+ by S&P, which do not mature or have a demand feature at par

**** Municipal Securities rated less than Baa3 by Moody's or less than BBB by
     S&P or not rated by Moody's or S&P.

     Since the Moody's Exposure Period currently applicable to the Fund is 49
days, the Moody's Discount Factors currently applicable to Moody's Eligible
Assets will be determined by reference to the factors set forth opposite the
line entitled "7 weeks." Notwithstanding the foregoing, (i) the Moody's Discount
Factor for short-term Municipal Securities will be 115%, so long as such
Municipal Securities are rated at least MIG-1, VMIG-1 or P-1 by Moody's and
mature or have a demand feature at par exercisable in 30 days or less or 125% as
long as such Municipal Securities are rated at least A-1+/AA or SP-1+/AA by S&P
and mature or have a demand feature at par exercisable in 30 days or less and
(ii) no Moody's Discount Factor will be applied to cash or to Receivables for
Municipal Securities Sold or futures, options and similar instruments (to the
extent such securities are Moody's Eligible Assets); provided, however, that for
purposes of determining the Moody's Discount Factor applicable to a Municipal
Security, any Municipal Security (excluding any short-term Municipal Security)
not rated by Moody's but rated by S&P shall be deemed to have a Moody's rating
which is one full rating category lower than its S&P rating. "Receivables for
Municipal Securities 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 Municipal Securities 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 (x)
settled through clearing house firms with respect to which the Fund has received
prior written authorization from Moody's or (y) with counterparties having a
Moody's long-term debt rating of at least Baa3; and (ii) the Moody's Discounted
Value of Municipal Securities sold as of or

                                       43

prior to such Valuation Date which generated receivables, if such receivables
are due within five business days of such Valuation Date but do not comply with
either of conditions (x) or (y).

     The Moody's guidelines impose certain minimum issue size, issuer,
geographical diversification and other requirements for purposes of determining
Moody's Eligible Assets, as set forth in the table below:

** Municipal Securities rated less than Baa3 by Moody's or less than BBB by S&P
   or not rated by Moody's or S&P.

     The percentages set forth in the preceding table are based upon Moody's
Eligible Assets calculated excluding cash. Current Moody's guidelines by,
Moody's Eligible Asset shall mean that cash, Receivables for Municipal
Securities Sold, futures, options and similar instruments (other than Inverse
Floaters) or a Municipal Security that (i) pays interest in cash, (ii) does not
have its Moody's rating, if applicable, suspended by Moody's, (iii) is part of
an issue of Municipal Securities of at least $10,000,000, and (iv) is not
subject to a covered call or a covered put option written by the Fund. Municipal
Securities which are not rated by Moody's or S&P may comprise no more than 40%
of the aggregate Market Value of Moody's Eligible Assets; provided however, that
if the Market Value of such Municipal Securities exceeds 40% of the aggregate
Market Value of Moody's Eligible Assets, a portion of such Municipal Securities
(selected by the Fund) shall not be considered Moody's Eligible Assets, so that
the Market Value of such Municipal Securities (excluding such portion) does not
exceed 40% of the aggregate Market Value of Moody's Eligible Assets; provided
however, that no such unrated Municipal Security shall be considered a Moody's
Eligible Asset if such Municipal Security shall be in "default", which term
shall mean for purposes of this definition, either (a) the nonpayment by the
issuer of interest or principal when due or (b) the notification of the Fund by
the trustee under the underlying indenture or other governing instrument for
such Municipal Security that the issuer will fail to pay when due principal or
interest on such Municipal Security. For purposes of determining the Moody's
Discount Factors applicable to such S&P-rated Municipal Securities, any such
Municipal Obligation (excluding short-term Municipal Securities) will be deemed
to have a Moody's rating which is one full rating category lower than its S&P
rating. For purposes of applying the foregoing requirements, Municipal
Securities rated MIG-1, VMIG-1, or P-1, or, if not rated by Moody's, rated
A-1+/AA or SP-1+/AA by S&P, will be considered to have a long-term rating of A.

REDEMPTION

  Optional Redemption.  Except as described below,


     (i) shares of Municipal Preferred are redeemable, at the option of the
Fund, as a whole or from time to time in part, on the second Business Day
preceding any Dividend Payment Date therefor, out of funds legally available
therefor in accordance with the Declaration of Trust and the Certificate, at a
redemption price per share equal to the sum of $25,000 plus an amount equal to
accumulated but unpaid dividends thereon (whether or not earned or declared) to
(but not including) the date fixed for redemption; provided, however, that (1)
shares of Municipal Preferred may not be redeemed in part if after such partial
redemption fewer than 500 shares remain outstanding; (2) unless otherwise
provided in the Certificate, shares of the series of Municipal Preferred are
redeemable by the Fund during the Initial Rate


                                       44
<PAGE>   92

Period thereof only on the second Business Day next preceding the last Dividend
Payment Date for such Initial Rate Period; and (3) subject to the next
succeeding sentence, the Notice of Special Rate Period relating to a Special
Rate Period of shares of the series of Municipal Preferred, as delivered to the
Auction Agent and filed with the Secretary of the Fund, may provide that such
shares shall not be redeemable during the whole or any part of such Special Rate
Period (except as provided in (ii) below) or shall be redeemable during the
whole or any part of such Special Rate Period only upon payment of such
redemption premium or premiums as shall be specified therein ("Special
Redemption Provisions"); and

     (ii) shares of Municipal Preferred are redeemable, at the option of the
Fund, as a whole but not in part, out of funds legally available therefor in
accordance with the Declaration and the Certificate, on the first day following
any Dividend Period thereof included in a Rate Period consisting of more than
364 Rate Period Days if, on the date of determination of the Applicable Rate for
shares of such series for such Rate Period, such Applicable Rate equaled or
exceeded on such date of determination the Treasury Note Rate for such Rate
Period, at a redemption price of $25,000 per share plus an amount equal to
accumulated but unpaid dividends thereon (whether or not earned or declared) to
(but not including) the date fixed for redemption.

     A Notice of Special Rate Period relating to shares of Municipal Preferred
for a Special Rate Period may contain Special Redemption Provisions only if the
Board of Trustees, after consultation with the Broker-Dealer or Broker-Dealers
for such Special Rate Period of such shares, determines that such Special
Redemption Provisions are in the best interest of the Fund.

     If fewer than all of the outstanding shares of Municipal Preferred are to
be redeemed as set forth above, the number of shares to be redeemed shall be
determined by the Board of Trustees, and such shares shall be redeemed pro rata
from the Holders of record of shares of such series (initially Cede & Co. as
nominee of the Securities Depository) in proportion to the number of such shares
held by such Holders. Since the nominee of the Securities Depository is the only
record holder of shares of Municipal Preferred, the Securities Depository will
determine the number of shares to be redeemed from the accounts of the Agent
Members. The Agent Members, in turn, may determine to redeem shares from some
persons listed on their records as beneficial owners (which may include an Agent
Member holding shares for its own account) without redeeming shares from the
accounts of other persons listed on their records as beneficial owners.

     The Fund may not mail a Notice of Redemption relating to an optional
redemption as described above on any date unless on such date (a) the Fund 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 (including any applicable premium) due to Holders of shares of
Municipal Preferred by reason of the redemption of such shares on such
redemption date and (b) the Discounted Value of Moody's Eligible Assets (if
Moody's is then rating the shares of Municipal Preferred) and the Discounted
Value of S&P Eligible Assets (if S&P is then rating the shares of Municipal
Preferred) each at least equal the Municipal Preferred Basic Maintenance Amount,
and would at least equal the Municipal Preferred Basic Maintenance Amount
immediately subsequent to such redemption if such redemption were to occur on
such date. For purposes of determining in clause (b) of the preceding sentence
whether the Discounted Value of Moody's Eligible Assets at least equals the
Municipal Preferred Basic Maintenance Amount, the Moody's Discount Factors
applicable to Moody's Eligible Assets will be determined by reference to the
first Moody's Exposure Period longer than the Moody's Exposure Period then
applicable to the Fund.


     Mandatory Redemption.  The Fund will be required to redeem, at a redemption
price equal to $25,000 per share plus accumulated but unpaid dividends thereon
(whether or not earned or declared) to (but not including) the date fixed by the
Board of Trustees for redemption (such amount, together with the redemption
prices described above under "-- Optional Redemption," being herein referred to
as the "Redemption Price"), certain of the shares of Municipal Preferred to the
extent permitted under the 1940 Act, the Declaration of Trust, the Certificate
and any applicable law, if the Fund fails to maintain the Municipal Preferred
Basic Maintenance Amount or the 1940 Act Municipal Preferred Asset Coverage in


                                       45
<PAGE>   93

accordance with the requirements of the rating agency or rating agencies then
rating the shares of Municipal Preferred and such failure is not cured on or
before the Municipal Preferred Basic Maintenance Cure Date or the 1940 Act Cure
Date (herein respectively referred to as a "Cure Date"), as the case may be. The
number of shares of Municipal Preferred to be redeemed will be equal to the
lesser of (a) the minimum number of shares of Municipal Preferred, together with
all other Preferred Shares subject to redemption or retirement, the redemption
of which, if deemed to have occurred immediately prior to the opening of
business on the Cure Date, would have resulted in the satisfaction of the
Municipal Preferred Basic Maintenance Amount or the 1940 Act Municipal Preferred
Asset Coverage, as the case may be, on such Cure Date (provided, however, that,
if there is no such minimum number of shares of Municipal Preferred and other
Preferred Shares the redemption or retirement of which would have had such
result, all shares of Municipal Preferred and Preferred Shares then outstanding
will be redeemed), and (b) the maximum number of shares of Municipal Preferred,
together with all other Preferred Shares subject to redemption or retirement,
that can be redeemed out of funds expected to be legally available therefor. In
determining the shares of Municipal Preferred required to be redeemed in
accordance with the foregoing, the Fund will allocate the number of shares
required to be redeemed to satisfy the Municipal Preferred Basic Maintenance
Amount or the 1940 Act Municipal Preferred Asset Coverage, as the case may be,
pro rata among shares of Municipal Preferred and any other Preferred Shares
subject to redemption or retirement.

     The Fund is required to effect such a mandatory redemption on or prior to
30 days after such Cure Date, except that if the Fund does not have funds
legally available under the Declaration, the Certificate and applicable law for
the redemption of all of the required number of shares of Municipal Preferred
and other Preferred Shares which are subject to mandatory redemption or
retirement or the Fund otherwise is unable to effect such redemption on or prior
to 30 days after such Cure Date, the Fund will redeem those shares of Municipal
Preferred and other Preferred Shares which it was unable to redeem on the
earliest practicable date on which it is able to effect such redemption. If
fewer than all of the outstanding shares of Municipal Preferred are to be
redeemed pursuant to a mandatory redemption, the number of shares of such series
to be redeemed shall be redeemed pro rata from the Holders of such shares in
proportion to the number of such shares held by such Holders, in the same manner
as described above in respect of optional redemptions of fewer than all
outstanding shares of Municipal Preferred.

     NOTICE OF REDEMPTION.  Notice of Redemption shall be given by mailing the
same to each Holder of the shares to be redeemed (initially Cede & Co. as
nominee of the Securities Depository), not more than 30 days prior to the date
fixed for redemption thereof, to the respective addresses of such Holders as the
same shall appear on the record books of the Fund ("Notice of Redemption"). Each
such Notice of Redemption shall state (i) the redemption date; (ii) the number
of shares of Municipal Preferred to be redeemed and the series thereof; (iii)
the CUSIP number for shares of such series; (iv) the Redemption Price; (v) the
place or places where certificate(s) for such shares (properly endorsed or
assigned for transfer, if the Board of Trustees shall so require and the Notice
of Redemption shall so state) are to be surrendered for payment of the
Redemption Price; (vi) that dividends on the shares to be redeemed will cease to
accumulate on such redemption date; and (vii) the provisions of the Certificate
under which such redemption is made. If fewer than all shares of Municipal
Preferred held by any Holder are to be redeemed, the Notice of Redemption mailed
to such Holder shall also specify the number of shares of such series to be
redeemed from such Holder. The Fund may provide in any Notice of Redemption
relating to an optional redemption that such redemption is subject to one or
more conditions precedent and that the Fund shall not be required to effect such
redemption unless each such condition shall have been satisfied at the time or
times and in the manner specified in such Notice of Redemption.


     OTHER REDEMPTION PROCEDURES.  To the extent that any redemption for which
Notice of Redemption has been mailed is not made by reason of the absence of
legally available funds therefor in accordance with the Declaration of Trust,
the Certificate, and applicable law, such redemption will be made as soon as
practicable to the extent such funds become available. Failure to redeem shares
of Municipal Preferred will be deemed to exist at any time after the date
specified for redemption in a Notice of Redemption when the Fund shall have
failed, for any reason whatsoever, to deposit in trust with the Auction Agent
the


                                       46
<PAGE>   94

Redemption Price with respect to any shares for which such Notice of Redemption
has been mailed. Notwithstanding the fact that the Fund may not have redeemed
shares of Municipal Preferred for which a Notice of Redemption has been mailed,
dividends may be declared and paid on shares of Municipal Preferred and will
include those shares of Municipal Preferred for which Notice of Redemption has
been mailed. The first two sentences of this paragraph shall not apply in the
event the Fund provides in any Notice of Redemption relating to an optional
redemption that such redemption is subject to one or more conditions precedent
and any such condition precedent shall not have been satisfied at the time or
times and in the manner specified in such Notice of Redemption.

     Provided a Notice of Redemption has been mailed as described above, upon
the deposit with the Auction Agent (on the Business Day next preceding the date
fixed for redemption thereby, in funds available on the next Business Day in The
City of New York, New York) of funds sufficient to redeem the shares of
Municipal Preferred that are the subject of such notice, dividends on such
shares will cease to accumulate and such shares will no longer be deemed
outstanding for any purpose, and all rights of the Holders of the shares so
called for redemption will cease and terminate, except the right of the Holders
thereof to receive the Redemption Price, but without any interest or other
additional amount, except as otherwise provided above under
"-- Dividends -- Determination of Dividend Rate" and "-- Gross-up Payments."
Upon surrender in accordance with the Notice of Redemption of the certificates
for any shares so redeemed (properly endorsed or assigned for transfer, if the
Board of Trustees shall so require and the notice shall so state), the
Redemption Price shall be paid by the Auction Agent to the Holders of shares of
Municipal Preferred subject to redemption. In the case that fewer than all of
the shares represented by any such certificate are redeemed, a new certificate
shall be issued, representing the unredeemed shares, without cost to the Holder
thereof. The Fund will be entitled to receive from the Auction Agent, promptly
after the date fixed for redemption, any cash deposited with the Auction Agent
in excess of (i) the aggregate Redemption Price of the shares of Municipal
Preferred called for redemption on such date and (ii) all other amounts to which
Holders of shares of Municipal Preferred called for redemption may be entitled.
Any funds so deposited that are unclaimed at the end of 90 days from such
redemption date will, to the extent permitted by law, be repaid to the Fund,
after which time the Holders of shares of Municipal Preferred so called for
redemption may look only to the Fund for payment of the Redemption Price and all
other amounts to which they may be entitled. The Fund will be entitled to
receive, from time to time after the date fixed for redemption, any interest on
the funds so deposited.

     Notwithstanding the foregoing, if any dividends on shares of the series of
Municipal Preferred (whether or not earned or declared) are in arrears, no
shares of such series shall be redeemed unless all outstanding shares of such
series are simultaneously redeemed, and the Fund shall not purchase or otherwise
acquire any shares of such series; provided, however, that the foregoing shall
not prevent the purchase or acquisition of all outstanding shares of such series
pursuant to the successful completion of an otherwise lawful purchase or
exchange offer made on the same terms to, and accepted by, Holders of all
outstanding shares of such series.


     Except as described above with respect to redemptions and under "The
Auction -- Orders by Existing Holders and Potential Holders," the Declaration of
Trust and the Certificate do not prohibit the Fund or any affiliate of the Fund
from purchasing or otherwise acquiring any shares of Municipal Preferred.


     The Fund has the right to arrange for third parties to purchase from the
Holders thereof shares of Municipal Preferred which are to be redeemed as
described above.

LIQUIDATION

     Upon a dissolution, liquidation or winding up of the affairs of the Fund,
whether voluntary or involuntary, the Holders of shares of Municipal Preferred
then outstanding will be entitled to receive and to be paid out of the assets of
the Fund available for distribution to its shareholders, before any payment or
distribution shall be made on the Common Shares or on any other class of shares
of the Fund ranking junior to the Municipal Preferred upon dissolution,
liquidation or winding up, an amount equal to the liquidation preference with
respect to such shares. The liquidation preference for shares of Municipal

                                       47
<PAGE>   95

Preferred shall be $25,000 per share, plus an amount equal to all dividends
thereon (whether or not earned or declared) accumulated but unpaid to (but not
including) the date of final distribution in same-day funds, together with any
applicable Gross-up Payments in connection with the dissolution, liquidation or
winding up of the Fund. After the payment to the Holders of the shares of
Municipal Preferred of the full preferential amounts provided for as described
herein, Holders of Municipal Preferred as such shall have no right or claim to
any of the remaining assets of the Fund. In the event the assets of the Fund
available for distribution to the Holders of shares of Municipal Preferred, upon
any dissolution, liquidation or winding up of the Fund, whether voluntary or
involuntary, shall be insufficient to pay in full all amounts to which such
Holders are entitled, no such distribution shall be made on account of any other
class or series of Preferred Shares ranking on a parity with the shares of
Municipal Preferred with respect to the distribution of assets upon such
dissolution, liquidation or winding up unless proportionate distributive amounts
shall be paid on account of the shares of Municipal Preferred, ratably, in
proportion to the full distributable amounts for which holders of all such
parity shares are respectively entitled upon such dissolution, liquidation or
winding up. Subject to the rights of the holders of any series or class or
classes of shares ranking on a parity with the shares of Municipal Preferred
with respect to the distribution of assets upon dissolution, liquidation or
winding up of the Fund, after payment shall have been made in full to the
Holders of the shares of Municipal Preferred as described herein, but not prior
thereto, any other series or class or classes of shares ranking junior to the
shares of Municipal Preferred with respect to the distribution of assets upon
dissolution, liquidation or winding up shall, subject to the respective terms
and provisions (if any) applying thereto, be entitled to receive any and all
assets remaining to be paid or distributed, and the Holders of the shares of
Municipal Preferred shall not be entitled to share therein.

     Neither the sale of all or substantially all the property or business of
the Fund, nor the merger or consolidation of the Fund into or with any
Massachusetts business trust or corporation nor the merger or consolidation of
any Massachusetts business trust or corporation into or with the Fund shall be a
dissolution, liquidation or winding up, whether voluntary or involuntary, for
the purposes of the foregoing paragraph.

                          REPURCHASE OF COMMON SHARES

     The Fund is a closed-end investment company and as such its shareholders
will not have the right to cause the Fund to redeem their shares. Common Shares
trade in the open market at a price that is a function of several factors,
including net asset value and yield. Shares of closed-end management investment
companies frequently trade at a discount from net asset value but in some cases
trade at a premium. The Board of Trustees reviews, at least quarterly, the
advisability of taking action to reduce or eliminate any material discount from
net asset value in respect of Common Shares, which may include the repurchase of
such shares in the open market or in private transactions, the making of a
tender offer for such shares at net asset value, or the conversion of the Fund
to an open-end investment company. There can be no assurance, however, that the
Board of Trustees will decide to take any of these actions, or that share
repurchases or tender offers, if undertaken, will reduce market discount. In
addition, see "Description of Municipal Preferred -- Dividends -- Restrictions
on Dividends and Other Payments" for a discussion of the limitations on the
Fund's ability to engage in certain transactions.

     Although the decision to take action in response to a discount from net
asset value will be made by the Board of Trustees at the time it considers such
issue, it is the Board's present policy, which may be changed by the Board, not
to authorize repurchases of the Fund's Common Shares or a tender offer for such
shares if (1) such transactions, if consummated, would (a) result in the
delisting of the Common Shares from the NYSE, or (b) impair the Fund's status as
a regulated investment company under the Code (which would make the Fund a
taxable entity, causing the Fund's income to be taxed at the corporate level in
addition to the taxation of shareholders who receive dividends from the Fund) or
as a registered closed-end investment company under the 1940 Act; (2) the Fund
would not be able to liquidate portfolio securities in an orderly manner and
consistent with the Fund's investment objectives and policies in order to
repurchase shares; or (3) there is, in the Board's judgment, any (a) material
legal action or proceeding instituted or threatened challenging such
transactions or otherwise materially
                                       48
<PAGE>   96

adversely affecting the Fund, (b) general suspension of or limitation on prices
for trading securities on the NYSE, (c) declaration of a banking moratorium by
Federal or state authorities or any suspension of payment by United States or
New York State banks in which the Fund invests, (d) material limitation
affecting the Fund or the issuers of its portfolio securities by Federal or
state authorities on the extension of credit by lending institutions, (e)
commencement of war, armed hostilities or other international or national
calamity directly or indirectly involving the United States, or (f) other event
or condition which would have a material adverse effect (including any adverse
tax effect) on the Fund or its shareholders if shares were repurchased. The
Board of Trustees may in the future modify these conditions in light of
experience. Before deciding whether to take any action in response to a discount
from net asset value, the Board of Trustees would consider all relevant factors,
such as the extent and duration of the discount, the liquidity of the Fund's
portfolio, the impact of any action that might be taken on the Fund or its
shareholders, and market considerations. Based on these considerations, even if
the Fund's Common Shares should trade at a discount, the Board may determine
that, in the interest of the Fund and its shareholders, no action should be
taken.

                                     TAXES

     Set forth below is a discussion of certain U.S. federal income tax issues
concerning the Fund and the purchase, ownership, and disposition of Municipal
Preferred. This discussion does not purport to be complete or to deal with all
aspects of federal income taxation that may be relevant to shareholders in light
of their particular circumstances. This discussion is based upon present
provisions of the Internal Revenue Code of 1986, as amended (the "Code"), the
regulations promulgated thereunder, and judicial and administrative ruling
authorities, all of which are subject to change, which change may be
retroactive. Prospective investors should consult their own tax advisers with
regard to the federal tax consequences of the purchase, ownership, or
disposition of Fund shares, as well as the tax consequences arising under the
laws of any state, foreign country, or other taxing jurisdiction.

TAX STATUS OF THE FUND

     The Fund has elected to be, and intends to qualify for treatment each year,
as a regulated investment company under Subchapter M of the Code. Accordingly,
the Fund intends to satisfy certain requirements relating to sources of its
income and diversification of its assets and to distribute substantially all of
its net investment income and including tax-exempt income and net capital gain
in accordance with the timing requirements imposed by the Code, so as to
maintain its regulated investment company status. By doing so, the Fund will
avoid any federal income tax on any income and gain it distributes to its
shareholders. If the Fund failed to qualify for treatment as a regulated
investment company for any taxable year, it would be taxed on the full amount of
its taxable income for that year without being able to deduct the distributions
it makes to its shareholders and the shareholders would treat all distributions,
including those that otherwise would qualify as "exempt-interest dividends"
(described below), as dividends (that is, ordinary income) to the extent of the
Fund's' earnings and profits.

     Accordingly, the Fund must, among other things, (a) derive in each taxable
year at least 90% of its gross income from dividends, interest, payments with
respect to certain securities loans, and gains from the sale or other
disposition of stock, securities or foreign currencies, or other income derived
with respect to its business of investing in such stock, securities or
currencies; and (b) diversify its holdings so that, at the end of each fiscal
quarter, (i) at least 50% of the value of the Fund's total assets is represented
by cash and cash items, U.S. Government securities, the securities of other
regulated investment companies and other securities, with such other securities
limited, in respect of any one issuer, to an amount not greater than 5% of the
value of the Fund's total assets and 10% of the outstanding voting securities of
such issuer, and (ii) not more than 25% of the value of its total assets is
invested in the securities of any one issuer (other than U.S. Government
securities and the securities of other regulated investment companies).

     Amounts not distributed on a timely basis in accordance with a calendar
year distribution requirement are subject to a nondeductible 4% excise tax at
the Fund level. To avoid the tax, the Fund must distribute

                                       49
<PAGE>   97

during each calendar year an amount equal to the sum of (1) at least 98% of its
ordinary income (not taking into account any capital gains or losses) for the
calendar year, (2) at least 98% of its capital gain (net income) for a one-year
period generally ending on October 31 of the calendar year, and (3) all ordinary
income and capital gain (net income) for previous years that were not
distributed during such years. To avoid application of the excise tax, the Fund
intends to make distributions in accordance with the calendar year distribution
requirement.

DISTRIBUTIONS

     In general, distributions of net investment income and net capital gain are
taxable to a U.S. shareholder as ordinary income, whether paid in cash or
shares. See "Tax-Exempt Income" below.

     The Fund will designate distributions made to holders of Common Shares and
to holders of Preferred Shares, including the Municipal Preferred, in accordance
with each class's proportionate share of each item of Fund income (such as
tax-exempt interest, net capital gain and other taxable income).

     Shareholders will be notified annually as to the U.S. federal tax status of
distributions, and shareholders receiving distributions in the form of newly
issued shares will receive a report as to the net asset value of the shares
received.

TAX-EXEMPT INCOME


     The Fund intends to invest a sufficient amount of its assets in Municipal
Securities to qualify to distribute "exempt-interest dividends" (as defined in
the Code) to shareholders. The Fund's dividends payable from net tax-exempt
interest earned from Municipal Securities will qualify as exempt-interest
dividends if, at the close of each quarter of the Fund's taxable year, at least
50% of the value of its total assets consists of securities the interest on
which is exempt from the regular federal income tax under Code section 103.
Exempt-interest dividends distributed to shareholders are not included in
shareholders' gross income for regular federal income tax purposes, but
shareholders are nonetheless required to report tax-exempt-interest dividends on
their federal income tax returns. As noted above, the portion of exempt-
interest dividends attributable to interest on certain Municipal Securities is
treated as a preference item. The Fund will determine periodically which
distributions will be designated as exempt-interest dividends. If the Fund earns
income which is not eligible to be so designated, the Fund intends to distribute
such income. Such distributions will be subject to federal, state and local
taxes, as applicable, in the hands of shareholders.


     Interest on certain types of private activity bonds is not exempt from
federal income tax when received by "substantial users" (as defined in the
Code). A "substantial user" includes any "nonexempt person" who regularly uses
in trade or business part of a facility financed from the proceeds of private
activity bonds. The Fund may invest periodically in private activity bonds and,
therefore, may not be an appropriate investment for entities that are
substantial users of facilities financed by private activity bonds or "related
persons" of substantial users. Generally, an individual will not be a related
person of a substantial user under the Code unless he/she or his/her immediate
family owns indirectly in aggregate more than 50% of the equity value of the
substantial user.

     Opinions relating to the tax status of interest derived from individual
Municipal Securities are rendered by bond counsel to the issuer. Although the
Fund's adviser attempts to determine that any security it contemplates
purchasing on behalf of the Fund is issued with an opinion indicating that
interest payments will be exempt from federal and (as applicable) state tax,
neither the Adviser nor the Fund's counsel makes any review of proceedings
relating to the issuance of Municipal Securities or the bases of such opinions.

     Interest on indebtedness incurred or continued by a shareholder to purchase
or carry Municipal Preferred is not deductible for federal income tax purposes
to the extent that interest relates to exempt-interest dividends received from
the Fund.

                                       50
<PAGE>   98

     From time to time, proposals have been introduced in Congress for the
purpose of restricting or eliminating the federal income tax exemption for
interest on Municipal Securities, and similar proposals may be introduced in the
future. If such a proposal were enacted, the availability of Municipal
Securities for investment by the Fund could be adversely affected. Under these
circumstances, Fund management would re-evaluate the Fund's investment
objectives and policies and would consider either changes in the structure of
the Fund or its dissolution.

BACKUP WITHHOLDING

     The Fund generally will be required to withhold federal income tax at a
rate of 31% ("backup withholding") from dividends paid (other than
exempt-interest dividends), and capital gain distributions to individuals and
certain other non-corporate shareholders if (1) the shareholder fails to furnish
the Fund with the shareholder's correct taxpayer identification number or social
security number, (2) the IRS notifies the shareholder or the Fund that the
shareholder has failed to report properly certain interest and dividend income
to the IRS and to respond to notices to that effect, or (3) when required to do
so, the shareholder fails to certify that he or she is not subject to backup
withholding. Any amounts withheld may be credited against the shareholder's
federal income tax liability.

OTHER TAXATION

     An investment in Municipal Preferred is not appropriate for non-U.S.
investors or as a retirement plan investment. Non-U.S. shareholders may be
subject to U.S. tax rules that differ significantly from those summarized above,
including the likelihood that ordinary income dividends to them would be subject
to withholding of U.S. tax at a rate of 30% (or a lower treaty rate, if
applicable).

STATE AND LOCAL TAXES

     The exemption of interest income for federal income tax purposes does not
necessarily result in exemption under the income or other tax laws of any state
or local taxing authority. Shareholders of the Fund may be exempt from state and
local taxes on distributions of tax-exempt interest income derived from
obligations of the state and/or municipalities of the state in which they are
resident, but taxable generally on income derived from obligations of other
jurisdictions. The Fund will report annually to shareholders the percentages
representing the proportionate ratio of its net tax-exempt income earned in each
state.

                             RATINGS OF INVESTMENTS

     STANDARD & POOR'S CORPORATION -- A brief description of the applicable
Standard & Poor's Corporation ("S&P") rating symbols and their meanings (as
published by S&P) follows:

LONG TERM DEBT

     An S&P corporate or municipal debt rating is a current assessment of the
creditworthiness of an obligor with respect to a specific obligation. This
assessment may take into consideration obligors such as guarantors, insurers, or
lessees.

     The debt rating is not a recommendation to purchase, sell, or hold a
security, inasmuch as it does not comment as to market price or suitability for
a particular investor.

     The ratings are based on current information furnished by the issuer or
obtained by S&P from other sources it considers reliable. S&P does not perform
an audit in connection with any rating and may, on occasion, rely on unaudited
financial information. The ratings may be changed, suspended, or withdrawn as a
result of changes in, or unavailability of, such information, or based on other
circumstances.

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

          1. 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;

          2. Nature of and provisions of the obligation;

          3. Protection afforded by, and relative position of, the obligation in
     the event of bankruptcy, reorganization, or other arrangement under the
     laws of bankruptcy and other laws affecting creditors' rights.

INVESTMENT GRADE

AAA  Debt rated 'AAA' has the highest rating assigned by S&P. Capacity to pay
     interest and repay principal is extremely strong.

AA    Debt rated 'AA' has a very strong capacity to pay interest and repay
      principal and differs from the highest rated issues only in small degree.

A      Debt rated 'A' has a strong capacity to pay interest and repay principal
       although it is somewhat more susceptible to the adverse effects of
       changes in circumstances and economic conditions than debt in higher
       rated categories.

BBB   Debt rated 'BBB' is regarded as having an adequate capacity to pay
      interest and repay principal. Whereas it normally exhibits adequate
      protection parameters, adverse economic conditions or changing
      circumstances are more likely to lead to a weakened capacity to pay
      interest and repay principal for debt in this category than in higher
      rated categories.

SPECULATIVE GRADE RATING

     Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded as having
predominantly speculative characteristics with respect to capacity to pay
interest and repay principal. 'BB' indicates the least degree of speculation and
'C' the highest. While such debt will likely have some quality and protective
characteristics, these are outweighed by major uncertainties or major exposures
to adverse conditions.

BB    Debt rated 'BB' has less near-term vulnerability to default than other
      speculative issues. However, it faces major ongoing uncertainties or
      exposure to adverse business, financial, or economic conditions which
      could lead to inadequate capacity to meet timely interest and principal
      payments.

                                       58
<PAGE>   106

      The 'BB' rating category is also used for debt subordinated to senior debt
      that is assigned an actual or implied 'BBB-' rating.

B      Debt rated 'B' has a greater vulnerability to default but currently has
       the capacity to meet interest payments and principal repayments. Adverse
       business, financial, or economic conditions will likely impair capacity
       or willingness to pay interest and repay principal. The 'B' rating
       category is also used for debt subordinated to senior debt that is
       assigned an actual or implied 'BB' or 'BB-' rating.

CCC  Debt rated 'CCC' has a currently identifiable vulnerability to default, and
     is dependent upon favorable business, financial, and economic conditions to
     meet timely payment of interest and repayment of principal. In the event of
     adverse business, financial, or economic conditions, it is not likely to
     have the capacity to pay interest and repay principal.

     The 'CCC' rating category is also used for debt subordinated to senior debt
     that is assigned an actual or implied 'B' or 'B-' rating.

CC    The rating 'CC' typically is applied to debt subordinated to senior debt
      that is assigned an actual or implied 'CCC' debt rating.

C      The rating 'C' typically is applied to debt subordinated to senior debt
       which is assigned an actual or implied 'CCC-' debt rating. The 'C' rating
       may be used to cover a situation where a bankruptcy petition has been
       filed, but debt service payments are continued.

CI     The rating 'CI' is reserved for income bonds on which no interest is
       being paid.

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 S&P 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 if debt
       service payments are jeopardized.

     PLUS (+) OR MINUS (-):  The ratings from 'AA' to 'CCC' may be modified by
the addition of a plus or minus sign to show relative standing within the major
rating categories.

c       The "c" subscript is used to provide additional information to investors
        that the bank may terminate its obligation to purchase tendered bonds if
        the long-term credit rating of the issuer is below an investment-grade
        level and/or the issuer's bonds are deemed taxable.

     PROVISIONAL RATINGS:  The letter "p" indicates that the rating is
provisional. A provisional rating assumes the successful completion of the
project financed by the debt being rated and indicates that payment of debt
service requirements is largely or entirely dependent upon the successful and
timely completion of the project. This rating, however, while addressing credit
quality subsequent to completion of the project, makes no comment on the
likelihood of, or the risk of default upon failure of, such completion. The
investor should exercise judgment with respect to such likelihood and risk.

L      The letter "L" indicates that the rating pertains to the principal amount
       of those bonds to the extent that the underlying deposit collateral is
       federally insured and interest is adequately collateralized.* In the case
       of certificates of deposit the letter 'L' indicates that the deposit,
       combined with other deposits being held in the same right and capacity,
       will be honored for principal and accrued pre-default interest up to the
       federal insurance limits within 30 days after closing of the insured
       institution or, in the event that the deposit is assumed by a successor
       insured institution, upon maturity.

*      Continuance of the rating is contingent upon S&P's receipt of an executed
       copy of the escrow agreement or closing documentation confirming
       investments and cash flow.

NR    Indicates no rating has been requested, that there is insufficient
      information on which to base a rating, or that S&P does not rate a
      particular type of obligation as a matter of policy.

                                       59
<PAGE>   107

r       The "r" highlights derivative, hybrid and certain other obligations that
        Standard & Poor's believes may experience high volatility or variability
        in expected returns as a result of noncredit risks. Examples of such
        obligations are equities, commodities or currencies; certain swaps and
        options; and interest-only and principal-only mortgage securities. The
        absence of an 'r' symbol should not be taken as an indication that an
        obligation will exhibit no volatility or variability in total return.

MUNICIPAL NOTES

     An S&P note rating reflects the liquidity concerns and market access risks
unique to notes. Notes due in 3 years or less will likely receive a note rating.
Notes maturing beyond 3 years will most likely receive a long-term debt rating.
The following criteria will be used in making that assessment:

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

     -- Source of payment (the more dependent the issue is on the market for its
        refinancing, the more likely it will be treated as a note).

NOTE RATING SYMBOLS ARE AS FOLLOWS:

SP-1  Very strong or strong capacity to pay principal and interest. Those issues
      determined to possess overwhelming safety characteristics will be given a
      plus (+) designation.

SP-2  Satisfactory capacity to pay principal and interest.

SP-3  Speculative capacity to pay principal and interest.

     A note rating is not a recommendation to purchase, sell, or hold a security
inasmuch as it does not comment as to market price or suitability for a
particular investor. The ratings are based on current information furnished to
S&P by the issuer or obtained by S&P from other sources it considers reliable.
S&P does not perform an audit in connection with any rating and may, on
occasion, rely on unaudited financial information. The ratings may be changed,
suspended, or withdrawn as a result of changes in or unavailability of such
information or based on other circumstances.

COMMERCIAL PAPER

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

A-1    This highest category 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-l."

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 S&P
       believes that such payments will be made during such grace period.

     A commercial paper rating is not a recommendation to purchase, sell, or
hold a security inasmuch as it does not comment as to market price or
suitability for a particular investor. The ratings are based on current
information furnished to S&P by the issuer or obtained by S&P from other sources
it considers reliable. S&P does not perform an audit in connection with any
rating and may, on occasion, rely on unaudited financial information. The
ratings may be changed, suspended, or withdrawn as a result of changes in or
unavailability of such information or based on other circumstances.

     MOODY'S INVESTORS SERVICE, INC. -- A brief description of the applicable
Moody's Investors Service, Inc. ("Moody's") rating symbols and their meanings
(as published by Moody's) follows:

     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 payment and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.

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

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

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

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

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

     Note -- Those bonds in the Aa, A, Baa, Ba and B categories which Moody's
believes possess the strongest credit attributes within those categories are
designated by the symbols Aa1, A1, Baa1, Ba1 and B1.

     Bonds for which the security depends upon the completion of some act or the
fulfillment of some condition are rated conditionally. These are bonds secured
by (a) earnings of projects under construction. (b) earnings of projects
unseasoned in operation experience, (c) rentals which begin when facilities are

                                       61
<PAGE>   109

completed, or (d) payments to which some other limiting condition attaches.
Parenthetical rating denotes probable credit stature upon completion of
construction or elimination of basis of condition.

     Short-term Notes -- The four ratings of Moody's for short-term notes are
MIG 1/VMIG1, MIG 2/ VMIG2, MIG 3/VMIG3 and MIG 4/VMIG4; MIG 1/VMIG1 denotes
"best quality . . . strong protection by established cash flows"; MIG 2/VMIG2
denotes "high quality" with ample margins of protection; MIG 3/VMIG3 notes are
of "favorable quality . . . but . . . lacking the undeniable strength of the
preceding grades"; MIG 4/VMIG4 notes are of "adequate quality . . . [p]rotection
commonly regarded as required of an investment security is present . . . there
is specific risk."

                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 ability of
rated issuers:

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

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

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

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

* Net amount subject to federal income tax after deductions and exemptions.

     The above indicated federal income tax brackets do not take into account
the effect of a reduction in the deductibility of itemized deductions for
individual taxpayers with adjusted gross income in excess of $126,600. The tax
brackets also do not show the effects of phaseout of personal exemptions for
single filers with adjusted gross income in excess of $126,600 and joint filers
with adjusted gross income in excess of $189,950. The effective marginal tax
rates and equivalent taxable yields of those taxpayers will be higher than those
indicated above.

     Yields shown are for illustration purposes only and are not meant to
represent the Fund's actual or expected yield. No assurance can be given that
the Fund will achieve any specific tax-exempt yield. While it is expected that
the Fund will invest principally in obligations the interest from which is
exempt from the regular federal income tax, other income received by the Fund
may be taxable. The table does not take into account state or local taxes, if
any, payable on Fund distributions. It should also be noted that the interest
earned on certain "private activity bonds", while exempt from the regular
federal income tax, is treated as a tax preference item which could subject the
recipient to the alternative minimum tax. The illustrations assume that the
alternative minimum tax is not applicable and do not take into account any tax
credits that may be available.

     The information set forth above is as of the date of this SAI. Subsequent
tax law changes could result in prospective or retroactive changes in the tax
brackets, tax rates, and tax-equivalent yields set forth above. Investors should
consult their tax adviser for additional information.

          (i) each Beneficial Owner of shares of such series may submit to its
     Broker-Dealer by telephone or otherwise information as to:

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

             (B) the number of Outstanding shares, if any, of such series held
        by such Beneficial Owner offers to sell if the Applicable Rate for
        shares of such series for the next succeeding Rate Period of shares of
        such series shall be less than the rate per annum specified by such
        Beneficial Owner; and/or

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

          (ii) one or more Broker-Dealers, using lists of Potential Beneficial
     Owners, shall in good faith for the purpose of conducting a competitive
     Auction in a commercially reasonable manner, contact Potential Beneficial
     Owners (by telephone or otherwise), including Persons that are not
     Beneficial Owners, on such lists to determine the number of shares, if any,
     of such series which each such Potential Beneficial Owner offers to
     purchase if the Applicable Rate for shares of such series for the next
     succeeding Rate Period of shares of such series shall not be less than the
     rate per annum specified by such Potential Beneficial Owner.

     For purposes hereof, the communication by a Beneficial Owner or Potential
Beneficial Owner to a Broker-Dealer, or by a Broker-Dealer to the Auction Agent,
of information referred to in clause (i)(A), (i)(B), (i)(C), or (ii) of this
paragraph (a) is hereinafter referred to as an "Order" and collectively as
"Orders" and each Beneficial Owner and each Potential Beneficial Owner placing
an Order with a Broker-Dealer, and such Broker-Dealer placing an Order with the
Auction Agent, is hereinafter referred to as a "Bidder" and collectively as
"Bidders"; an Order containing the information referred to in clause (i)(A) of
this paragraph (a) is hereinafter referred to as a "Hold Order" and collectively
as "Hold Orders"; an Order containing the information referred to in clause
(i)(B) or (ii) of this paragraph (a) is hereinafter referred to as a "Bid" and

series of Municipal Preferred subject to an Auction on any Auction Date shall
constitute an irrevocable offer to sell:

          (A) the number of Outstanding shares of such series specified in such
     Bid if the Applicable Rate for shares of such series determined on such
     Auction Date shall be less than the rate specified therein;

          (B) such number or a lesser number of Outstanding shares of such
     series to be determined as set forth in clause (iv) of paragraph (a) of

<PAGE>   114

          (C) the number of Outstanding shares of such series specified in such
     Bid if the rate specified therein shall be higher than the Maximum Rate for
     shares of such series, or such number or a lesser number of Outstanding
     shares of such series to be determined as set forth in clause (iii) of
     paragraph (b) of Section 4 of this Appendix D if the rate specified therein
     shall be higher than the Maximum Rate for shares of such series and
     Sufficient Clearing Bids for shares of such series do not exist.

     (ii) A Sell Order by a Beneficial Owner or an Existing Holder of shares of
the series of Municipal Preferred subject to an Auction on any Auction Date
shall constitute an irrevocable offer to sell:

          (A) the number of Outstanding shares of such series specified in such
     Sell Order; or

          (B) such number or a lesser number of Outstanding shares of such
     series as set forth in clause (iii) of paragraph (b) of Section 4 of this
     Appendix D if Sufficient Clearing Bids for shares of such series do not
     exist;

provided, however, that a Broker-Dealer that is an Existing Holder with respect
to shares of the series of Municipal Preferred shall not be liable to any Person
for failing to sell such shares pursuant to a Sell Order described in the
proviso to paragraph (c) of Section 2 of this Appendix D if (1) such shares were
transferred by the Beneficial Owner thereof without compliance by such
Beneficial Owner or its transferee Broker-Dealer (or other transferee person, if
permitted by the Fund) with the provisions of Section 7 of this Appendix D or
(2) such Broker-Dealer has informed the Auction Agent pursuant to the terms of
its Broker-Dealer Agreement that, according to such Broker-Dealer's records,
such Broker-Dealer believes it is not the Existing Holder of such shares.

     (iii) A Bid by a Potential Beneficial Holder or a Potential Holder of
shares of the series of Municipal Preferred subject to an Auction on any Auction
Date shall constitute an irrevocable offer to purchase:

     Auction Date shall be higher than the rate specified therein; or

          (B) such number or a lesser number of Outstanding shares of such
     series as set forth in clause (v) of paragraph (a) of Section 4 of this

     (c) No Order for any number of shares of Municipal Preferred other than

     2. SUBMISSION OF ORDERS BY BROKER-DEALERS TO AUCTION AGENT.

     (a) Each Broker-Dealer shall submit in writing to the Auction Agent prior
to the Submission Deadline on each Auction Date all Orders for shares of
Municipal Preferred of the series subject to an Auction on such Auction Date
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 shall specify with respect to each Order for such shares:

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

          (ii) the aggregate number of shares of such series that are the
     subject of such Order;

          (iii) to the extent that such Bidder is an Existing Holder of shares
     of such series:

             (A) the number of shares, if any, of such series subject to any
        Hold Order of such Existing Holder;

             (B) the number of shares, if any, of such series subject to any Bid
        of such Existing Holder and the rate specified in such Bid; and

                                       67
<PAGE>   115

             (C) the number of shares, if any, of such series subject to any
        Sell Order of such Existing Holder; and

          (iv) to the extent such Bidder is a Potential Holder of shares of such
     series, the rate and number of shares of such series specified in such
     Potential Holder's Bid.

     (b) If any rate 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%.

     (c) If an Order or Orders covering all of the Outstanding shares of
Municipal Preferred of the series held by any Existing Holder is not submitted
to the Auction Agent prior to the Submission Deadline, the Auction Agent shall
deem a Hold Order to have been submitted by or on behalf of such Existing Holder
covering the number of Outstanding shares of such series held by such Existing
Holder and not subject to Orders submitted to the Auction Agent; provided,
however, that if an Order or Orders covering all of the Outstanding shares of
such series held by any Existing Holder is not submitted to the Auction Agent
prior to the Submission Deadline for an Auction relating to a Special Rate
Period consisting of more than 28 Rate Period Days, the Auction Agent shall deem
a Sell Order to have been submitted by or on behalf of such Existing Holder
covering the number of outstanding shares of such series held by such Existing
Holder and not subject to Orders submitted to the Auction Agent.

     (d) If one or more Orders of an Existing Holder is submitted to the Auction
Agent covering in the aggregate more than the number of Outstanding shares of
Municipal Preferred of the series subject to an Auction held by such Existing
Holder, such Orders shall be considered valid in the following order of
priority:

          (i) all Hold Orders for shares of such series shall be considered
     valid, but only up to and including in the aggregate the number of
     Outstanding shares of such series held by such Existing Holder, and if the
     number of shares of such series subject to such Hold Orders exceeds the
     number of Outstanding shares of such series held by such Existing Holder,
     the number of shares subject to each such Hold Order shall be reduced pro
     rata to cover the number of Outstanding shares of such series held by such
     Existing Holder;

          (ii) (A) any Bid for shares of such series shall be considered valid
     up to and including the excess of the number of Outstanding shares of such
     series held by such Existing Holder over the number of shares of such
     series subject to any Hold Orders referred to in clause (i) above;

          (B) subject to subclause (A), if more than one Bid of an Existing
     Holder for shares of such series is submitted to the Auction Agent with the
     same rate and the number of Outstanding shares of such series subject to
     such Bids is greater than such excess, such Bids shall be considered valid
     up to and including the amount of such excess, and the number of shares of
     such series subject to each Bid with the same rate shall be reduced pro
     rata to cover the number of shares of such series equal to such excess;

          (C) subject to subclauses (A) and (B), if more than one Bid of an
     Existing Holder for shares of such series is submitted to the Auction Agent
     with different rates, such Bids shall be considered valid in the ascending
     order of their respective rates up to and including the amount of such
     excess; and

          (D) in any such event, the number, if any, of such Outstanding shares
     of such series subject to any portion of Bids considered not valid in whole
     or in part under this clause (ii) shall be treated as the subject of a Bid
     for shares of such series by or on behalf of a Potential Holder at the rate
     therein specified; and

          (iii) all Sell Orders for shares of such series shall be considered
     valid up to and including the excess of the number of Outstanding shares of
     such series held by such Existing Holder over the sum of shares of such
     series subject to valid Hold Orders referred to in clause (i) above and
     valid Bids referred to in clause (ii) above.

                                       68
<PAGE>   116

     (e) If more than one Bid for one or more shares of the series of Municipal
Preferred is submitted to the Auction Agent by or on behalf of any Potential
Holder, each such Bid submitted shall be a separate Bid with the rate and number
of shares therein specified.

     (f) 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.

     3. DETERMINATION OF SUFFICIENT CLEARING BIDS, WINNING BID RATE AND
APPLICABLE RATE.

     (a) Not earlier than the Submission Deadline on each Auction Date for
shares of the series of Municipal Preferred, the Auction Agent shall assemble
all valid Orders submitted or deemed submitted to it by the Broker-Dealers in
respect of shares of such series (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 collectively as "Submitted Hold
Orders," "Submitted Bids" or "Submitted Sell Orders," as the case may be, or as
"Submitted Orders") and shall determine for such series:

          (i) the excess of the number of Outstanding shares of such series over
     the number of Outstanding shares of such series subject to Submitted Hold
     Orders (such excess being hereinafter referred to as the "Available
     Municipal Preferred" of such series);

          (ii) from the Submitted Orders for shares of such series whether:

             (A) the number of Outstanding shares of such series subject to
        Submitted Bids of Potential Holders specifying one or more rates equal
        to or lower than the Maximum Rate for shares of such series;

          exceeds or is equal to the sum of:

             (B) the number of Outstanding shares of such series subject to
        Submitted Bids of Existing Holders specifying one or more rates higher
        than the Maximum Rate for shares of such series; and

             (C) the number of Outstanding shares of such series subject to
        Submitted Sell Orders (in the event such excess or such equality exists
        (other than because the number of shares of such series in subclauses
        (B) and (C) above is zero because all of the Outstanding shares of such
        series are subject to Submitted Hold Orders), such Submitted Bids in
        subclause (A) above being hereinafter referred to collectively as
        "Sufficient Clearing Bids" for shares of such series):

          (iii) if Sufficient Clearing Bids for shares of such series exist, the
     lowest rate specified in such Submitted Bids (the "Winning Bid Rate" for
     shares of such series) which if:

             (A) (I) each such Submitted Bid of Existing Holders specifying such
        lowest rate and (II) all other such Submitted Bids of Existing Holders
        specifying lower rates were rejected, thus entitling such Existing
        Holders to continue to hold the shares of such series that are subject
        to such Submitted Bids; and

             (B) (I) each such Submitted Bid of Potential Holders specifying
        such lowest rate and (II) all other such Submitted Bids of Potential
        Holders specifying lower rates were accepted;

would result in such Existing Holders described in subclause (A) above
continuing to hold an aggregate number of Outstanding shares of such series
which, when added to the number of Outstanding shares of such series to be
purchased by such Potential Holders described in subclause (B) above, would
equal not less than the Available Municipal Preferred of such series.

     (b) Promptly after the Auction Agent has made the determinations pursuant
to paragraph (a) of this Section 3, the Auction Agent shall advise the Fund of
the Maximum Rate for shares of the series of Municipal Preferred for which an
Auction is being held on the Auction Date and, based on such
                                       69
<PAGE>   117

determination, the Applicable Rate for shares of such series for the next
succeeding Rate Period thereof as follows:

          (i) if Sufficient Clearing Bids for shares of such series exist, that
     the Applicable Rate for all shares of such series for the next succeeding
     Rate Period thereof shall be equal to the Winning Bid Rate for shares of
     such series so determined;

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

          (iii) if all of the Outstanding shares of such series are subject to
     Submitted Hold Orders, that the Applicable Rate for all shares of such
     series for the next succeeding Rate Period thereof shall be as set forth in
     paragraph (c) of this Section 3.

     (c) For purposes of subparagraph (b)(iii) of this Section 3, the Applicable
Rate for shares of such series for the next succeeding Rate Period of shares of
such series shall be equal to the lesser of the Kenny Index (if such Rate Period
consists of fewer than 183 Rate Period Days) or the product of (A) (I) the "AA"
Composite Commercial Paper Rate on such Auction Date for such Rate Period, if
such Rate Period consists of fewer than 183 Rate Period Days; (II) the Treasury
Bill Rate on such Auction Date for such Rate Period, if such Rate Period
consists of more than 182 but fewer than 365 Rate Period Days; or (III) the
Treasury Note Rate on such Auction Date for such Rate Period, if such Rate
Period is more than 364 Rate Period Days (the rate described in the foregoing
clause (A)(I), (II) or (III), as applicable, being referred to herein as the
"Benchmark Rate") and (B) 1 minus the maximum marginal regular Federal
individual income tax rate applicable to ordinary income or the maximum marginal
regular Federal corporate income tax rate applicable to ordinary income,
whichever is greater; provided, however, that if the Fund has notified the
Auction Agent of its intent to allocate to shares of such series in such Rate
Period any net capital gains or other income taxable for Federal income tax
purposes ("Taxable Income"), the Applicable Rate for shares of such series for
such Rate Period will be (i) if the Taxable Yield Rate (as defined below) is
greater than the Benchmark Rate, then the Benchmark Rate, or (ii) if the Taxable
Yield Rate is less than or equal to the Benchmark Rate, then the rate equal to
the sum of (x) the lesser of the Kenny Index (if such Rate Period consists of
fewer than 183 Rate Period Days) or the product of the Benchmark Rate multiplied
by the factor set forth in the preceding clause (B) and (y) the product of the
maximum marginal regular Federal individual income tax rate applicable to
ordinary income or the maximum marginal regular Federal corporate income tax
applicable to ordinary income, whichever is greater, multiplied by the Taxable
Yield Rate. For purposes of the foregoing, Taxable Yield Rate means the rate
determined by (a) dividing the amount of Taxable Income available for
distribution per such share of Municipal Preferred by the number of days in the
Dividend Period in respect of which such Taxable Income is contemplated to be
distributed, (b) multiplying the amount determined in (a) above by 365 (in the
case of a Dividend Period of 7 Rate Period Days) or 360 (in the case of any
other Dividend Period), and (c) dividing the amount determined in (b) above by
$25,000.

     4. ACCEPTANCE AND REJECTION OF SUBMITTED BIDS AND SUBMITTED SELL ORDERS AND
ALLOCATION OF SHARES.  Existing Holders shall continue to hold the shares of
Municipal Preferred that are subject to Submitted Hold Orders, and, based on the
determinations made pursuant to paragraph (a)of Section 3 of this Appendix D,
the Submitted Bids and Submitted Sell Orders shall be accepted or rejected by
the Auction Agent and the Auction Agent shall take such other action as set
forth below:

          (a) If Sufficient Clearing Bids for shares of the series of Municipal
     Preferred have been made, all Submitted Sell Orders with respect to shares
     of such series shall be accepted and, subject to the provisions of
     paragraphs (d) and (e) of this Section 4, Submitted Bids with respect to
     shares of such

                                       70
<PAGE>   118

     series shall be accepted or rejected as follows in the following order of
     priority and all other Submitted Bids with respect to shares of such series
     shall be rejected:

             (i) Existing Holders' Submitted Bids for shares of such series
        specifying any rate that is higher than the Winning Bid Rate for shares
        of such series shall be accepted, thus requiring each such Existing
        Holder to sell the shares of Municipal Preferred subject to such
        Submitted Bids;

             (ii) Existing Holders' Submitted Bids for shares of such series
        specifying any rate that is lower than the Winning Bid Rate for shares
        of such series shall be rejected, thus entitling each such Existing
        Holder to continue to hold the shares of Municipal Preferred subject to
        such Submitted Bids;

             (iii) Potential Holders' Submitted Bids for shares of such series
        specifying any rate that is lower than the Winning Bid Rate for shares
        of such series shall be accepted;

             (iv) each Existing Holders' Submitted Bid for shares of such series
        specifying a rate that is equal to the Winning Bid Rate for shares of
        such series shall be rejected, thus entitling such Existing Holder to
        continue to hold shares of Municipal Preferred subject to such Submitted
        Bid, unless the number of Outstanding shares of Municipal Preferred
        subject to all such Submitted Bids shall be greater than the number of
        shares of Municipal Preferred ("remaining shares") in the excess of the
        Available Municipal Preferred of such series over the number of shares
        of Municipal Preferred subject to Submitted Bids described in clauses
        (ii) and (iii) of this paragraph (a), in which event such Submitted Bid
        of such Existing Holder shall be rejected in part, and such Existing
        Holder shall be entitled to continue to hold shares of Municipal
        Preferred subject to such Submitted Bid, but only in an amount equal to
        the number of shares of Municipal Preferred of such series obtained by
        multiplying the number of remaining shares by a fraction, the numerator
        of which shall be the number of Outstanding shares of Municipal
        Preferred held by such Existing Holder subject to such Submitted Bid and
        the denominator of which shall be the aggregate number of Outstanding
        shares of Municipal Preferred subject to such Submitted Bids may be all
        such Existing Holders that specified a rate equal to the Winning Bid
        Rate for shares of such series; and

             (v) each Potential Holder's Submitted Bid for shares of such series
        specifying a rate that is equal to the Winning Bid Rate of shares of
        such series shall be accepted but only in an amount equal to the number
        of shares of such series obtained by multiplying the number of shares in
        the excess of the Available Municipal Preferred of such series over the
        number of shares of Municipal Preferred subject to Submitted Bids
        described in clauses (ii) through (iv) of this paragraph (a) by a
        fraction, the numerator of which shall be the number of Outstanding
        shares of Municipal Preferred subject to such Submitted Bids and the
        denominator of which shall be the aggregate number of Outstanding shares
        of Municipal Preferred subject to such Submitted Bids made by all such
        Potential Holders that specified a rate equal to the Winning Bid Rate
        for shares of such series.

          (b) If Sufficient Clearing Bids for shares of the series of Municipal
     Preferred have not been made (other than because all of the Outstanding
     shares of such series are subject to Submitted Hold Orders), subject to the
     provisions of paragraph (d) of this Section 4, Submitted Orders for shares
     of such series shall be accepted or rejected as follows in the following
     orders of priority and all other Submitted Bids for shares of such series
     shall be rejected:

             (i) Existing Holder's Submitted Bids for shares of such series
        specifying any rate that is equal to or lower than the Maximum Rate for
        shares of such series shall be rejected, thus entitling such Existing
        Holders to continue to hold the shares of Municipal Preferred subject to
        such Submitted Bids;

             (ii) Potential Holders' Submitted Bids for shares of such series
        specifying any rate that is equal to or lower than the Maximum Rate for
        shares of such series shall be accepted; and

                                       71
<PAGE>   119

             (iii) Each Existing Holder's Submitted Bid for shares of such
        series specifying any rate that is higher than the Maximum Rate for
        shares of such series and the Submitted Sell Orders for shares of such
        series of each Existing Holder shall be accepted, thus entitling each
        Existing Holder that submitted or on whose behalf was submitted any such
        Submitted Bid or Submitted Sell Order to sell the shares of such series
        subject to such Submitted Bid or Submitted Sell Order, but in both cases
        only in an amount equal to the number of shares of such series obtained
        by multiplying the number of shares of such series subject to Submitted
        Bids described in clause (ii) of this paragraph (b) by a fraction, the
        numerator of which shall be the number of Outstanding shares of such
        series held by such Existing Holder subject to such Submitted Bid or
        Submitted Sell Order and the denominator of which shall be the aggregate
        number of Outstanding shares of such series subject to all such
        Submitted Bids and Submitted Sell Orders.

          (c) If all of the Outstanding shares of the series of Municipal
     Preferred are subject to Submitted Hold Orders, all Submitted Bids for
     shares of such series shall be rejected.

          (d) If, as a result of the procedures described in clause (iv) or (v)
     of paragraph (a) or clause (iii) of paragraph (b) of this Section 4, 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
     the series of Municipal Preferred on any Auction Date, the Auction Agent
     shall, in such manner as it shall determine in its sole discretion, round
     up or down the number of shares of Municipal Preferred of such series to be
     purchased or sold by any Existing Holder or Potential Holder on such
     Auction Date as a result of such procedures so that the number of shares so
     purchased or sold by each Existing Holder or Potential Holder on such
     Auction Date shall be whole shares of Municipal Preferred.

          (e) If, as a result of the procedures described in clause (v) of
     paragraph (a) of this Section 4, any Potential Holder would be entitled or
     required to purchase less than a whole share of series of Municipal
     Preferred on any Auction Date, the Auction Agent shall, in such manner as
     it shall determine in its sole discretion, allocate shares of Municipal
     Preferred of such series for purchase among Potential Holders so that only
     whole shares of Municipal Preferred of such series are purchased on such
     Auction Date as a result of such procedures by any Potential Holder, even
     if such allocation results in one or more Potential Holders not purchasing
     shares of Municipal Preferred of such series on such Auction Date.

          (f) Based on the results of each Auction for shares of the series of
     Municipal Preferred, the Auction Agent shall determine the aggregate number
     of shares of such series to be purchased and the aggregate number of shares
     of such series to be sold by Potential Holders and Existing Holders and,
     with respect to each Potential Holder and Existing Holder, to the extent
     that such aggregate number of shares to be purchased and such aggregate
     number of shares to be sold differ, determine to which other Potential
     Holder(s) or Existing Holder(s) they shall deliver, or from which other
     Potential Holder(s) or Existing Holder(s) they shall receive, as the case
     may be, shares of Municipal Preferred of such series. Notwithstanding any
     provision of the Auction Procedures or the Settlement Procedures to the
     contrary, in the event an Existing Holder or Beneficial Owner of shares of
     the series of Municipal Preferred with respect to whom a Broker-Dealer
     submitted a Bid to the Auction Agent for such shares that was accepted in
     whole or in part, or submitted or is deemed to have submitted a Sell Order
     for such shares that was accepted in whole or in part, fails to instruct
     its Agent Member to deliver such shares against payment therefor, partial
     deliveries of shares of Municipal Preferred that have been made in respect
     of Potential Holders' or Potential Beneficial Owners' Submitted Bids for
     shares of such series that have been accepted in whole or in part shall
     constitute good delivery to such Potential Holders and Potential Beneficial
     Owners.

          (g) Neither the Fund nor the Auction Agent nor any affiliate of either
     shall have any responsibility or liability with respect to the failure of
     an Existing Holder, a Potential Holder, a Beneficial Owner, a Potential
     Beneficial Owner or its respective Agent Member to deliver shares of

                                       72
<PAGE>   120

     Municipal Preferred of any series or to pay for shares of Municipal
     Preferred of any series sold or purchased pursuant to the Auction
     Procedures or otherwise.

     5. NOTIFICATION OF ALLOCATIONS.  Whenever the Fund intends to include any
net capital gain or other income taxable for Federal income tax purposes in any
dividend on shares of Municipal Preferred, the Fund shall, in the case of a
Minimum Rate Period or a Special Rate Period of 28 Rate Period Days or fewer,
and may, in the case of any other Special Rate Period, notify the Auction Agent
of the amount to be so included not later than the Dividend Payment Date next
preceding 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,
it will be required in turn to notify each Broker-Dealer, who, on or prior to
such Auction Date, in accordance with its Broker-Dealer Agreement, will be
required to notify its Beneficial Owners and Potential Beneficial Owners of
shares of Municipal Preferred believed by it to be interested in submitting an
Order in the Auction to be held on such Auction Date.

     6. AUCTION AGENT.  For so long as any shares of Municipal Preferred are
outstanding, the Auction Agent, duly appointed by the Fund to so act, shall be
in each case a commercial bank, trust company or other financial institution
independent of the Fund and its affiliates (which however, may engage or have
engaged in business transactions with the Fund or its affiliates) and at no time
shall the Fund or any of its affiliates act as the Auction Agent in connection
with the Auction Procedures. If the Auction Agent resigns or for any reason its
appointment is terminated during any period that any shares of Municipal
Preferred are outstanding, the Board of Trustees shall use its best efforts
promptly thereafter to appoint another qualified commercial bank, trust company
or financial institution to act as the Auction Agent. The Auction Agent's
registry of Existing Holders of shares of the series of Municipal Preferred
shall be conclusive and binding on the Broker-Dealers. A Broker-Dealer may
inquire of the Auction Agent between 3:00 p.m. on the Business Day preceding an
Auction for shares of the series of Municipal Preferred and 9:30 a.m. on the
Auction Date for such Auction to ascertain the number of shares of the series in
respect of which the Auction Agent has determined such Broker-Dealer to be an
Existing Holder. If such Broker-Dealer believes it is the Existing Holder of
fewer shares of such series than specified by the Auction Agent in response to
such Broker-Dealer's inquiry, such Broker-Dealer may so inform the Auction Agent
of that belief. Such Broker-Dealer shall not, in its capacity as Existing Holder
of shares of such series, submit Orders in such Auction in respect of shares of
such series covering in the aggregate more than the number of shares of such
series specified by the Auction Agent in response to such Broker-Dealer's
inquiry.

     7. TRANSFER OF SHARES OF MUNICIPAL PREFERRED.  Unless otherwise permitted
by the Fund, a Beneficial Owner or an Existing Holder may sell, transfer or
otherwise dispose of shares of Municipal Preferred only in whole shares and only
pursuant to a Bid or Sell Order placed with the Auction Agent in accordance with
the procedures described in this Appendix D or to a Broker-Dealer; provided,
however, that (a) a sale, transfer or other disposition of shares of Municipal
Preferred from a customer of a Broker-Dealer who is listed on the records of
that Broker-Dealer as the holder of such shares to that Broker-Dealer or another
customer of that Broker-Dealer shall not be deemed to be a sale, transfer or
other disposition for purposes of this Section 7 if such Broker-Dealer remains
the Existing Holder of the shares so sold, transferred or disposed of
immediately after such sale, transfer or disposition and (b) in the case of all
transfers other than pursuant to Auctions, the Broker-Dealer (or other Person,
if permitted by the Fund) to whom such transfer is made shall advise the Auction
Agent of such transfer.

     8. GLOBAL CERTIFICATE.  Prior to the commencement of a Voting Period, (i)
all of the shares of the series of Municipal Preferred outstanding from time to
time shall be represented by a global certificate registered in the name of the
Securities Depository or its nominee and (ii) no registration of transfer of
shares of the series of Municipal Preferred shall be made on the books of the
Fund to any Person other than the Securities Depository or its nominee.

ITEM 29.  INDEMNIFICATION

     Article VIII of the Registrant's Amended and Restated Agreement and
Declaration of Trust, dated February 27, 1989, provides in effect that the
Registrant will indemnify its officers and trustees under certain circumstances.
However, in accordance with Section 17(h) and 17(i) of the Investment Company
Act of 1940 and its own terms, said Article of the Amended and Restated
Agreement and Declaration of Trust does not protect any person against any
liability to the Registrant or its shareholders to which he would otherwise be
subject by reason of willful misfeasance, bad faith, gross negligence, or
reckless disregard of the duties involved in the conduct of his office.

                                * * * * * * * *

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to trustees, officers and controlling persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant has
been advised that, in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Act and is,
therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than payment by the Registrant of expenses incurred or
paid by a trustee, officer or controlling person of the Registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
trustee, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question as to whether such indemnification by itself is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
