     Calamos Convertible Opportunities and Income Fund (the "Fund") is a
recently organized, diversified, closed-end management investment company. The
Fund's investment objective is to provide total return, through a combination of
capital appreciation and current income. Under normal circumstances, the Fund
will invest at least 80% of its managed assets in a diversified portfolio of
convertible securities and non-convertible income securities. The portion of the
Fund's assets invested in convertible securities and non-convertible income
securities will vary from time to time consistent with the Fund's investment
objective, changes in equity prices and changes in interest rates and other
economic and market factors, although, under normal circumstances, the Fund will
invest at least 50% of its managed assets in convertible securities. "Managed
assets" means the total assets of the Fund (including any assets attributable to
any leverage that may be outstanding) minus the sum of accrued liabilities
(other than debt representing financial leverage). A substantial portion of the
Fund's assets may be invested in below investment grade (high yield, high risk)
securities. Below investment grade (high yield, high risk) securities are rated
Ba or lower by Moody's Investors Service, Inc. ("Moody's") or BB or lower by
Standard & Poor's Ratings Group, a division of The McGraw Hill Companies
("Standard & Poor's") or are unrated securities of comparable quality as
determined by the Fund's investment adviser. Below investment grade securities
are commonly referred to as "junk bonds" and are considered speculative with
respect to the issuer's capacity to pay interest and repay principal. They
involve greater risk of loss, are subject to greater price volatility and are
less liquid, especially during periods of economic uncertainty or change, than
higher rated debt securities. There can be no assurance that the Fund will
achieve its investment objective.

     INVESTING IN THE FUND'S PREFERRED SHARES INVOLVES RISKS THAT ARE DESCRIBED
IN "RISK FACTORS" BEGINNING ON PAGE    OF THIS PROSPECTUS. THE MINIMUM PURCHASE
AMOUNT OF THE PREFERRED SHARES IS $25,000.

THE OFFERING..................   We are offering      Series           Preferred
                                 Shares,      Series           Preferred Shares,
                                      Series           Preferred Shares,
                                 Series           Preferred Shares and
                                 Series           Preferred Shares, each at a
                                 purchase price of $25,000 per share. The
                                 Preferred Shares are offered through a group of
                                 underwriters led by           .

                                 The Preferred Shares entitle their holders to
                                 receive cash dividends at an annual rate that
                                 may vary for the successive dividend periods
                                 for the Preferred Shares. In general, except as
                                 described under "-- Dividends and Dividend
                                 Periods" below and "Description of Preferred
                                 Shares -- Dividends and Dividend Periods," the
                                 dividend period for the Series
                                 Preferred Shares will be seven days and Series
                                           Preferred Shares will be 28 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 rate period. See "The Auction."

                                 The Preferred Shares are not listed on an
                                 exchange. Instead, investors may buy or sell
                                 Preferred Shares in an auction by submitting
                                 orders to broker-dealers that have entered into
                                 an agreement with the auction agent and the
                                 Fund.

                                 Generally, investors in 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
                                 broker-dealer will maintain record ownership of
                                 Preferred Shares in book-entry form. An
                                 investor's broker-dealer, in turn, will
                                 maintain records of that investor's beneficial
                                 ownership of Preferred Shares.

                                 An investor should consider whether to invest
                                 in a particular series based on the series'
                                 rate of return, the investor's time horizon for

                                 28 day dividend period. The Series           ,
                                 a 28 day tranche, may be suited for investors
                                 with a longer investment horizon.

INVESTMENT OBJECTIVE..........   The Fund's investment objective is to provide
                                 total return, through a combination of capital
                                 appreciation and current income. There can be
                                 no assurance that the Fund will achieve its
                                 investment objective. See "Investment Objective
                                 and Principal Investment
                                 Strategies -- Investment Objective."

INVESTMENT POLICIES...........   Primary Investments.  Under normal
                                 circumstances, the Fund invests at least 80% of
                                 its managed assets in a diversified portfolio
                                 of convertible securities and non-convertible
                                 income securities. The portion of the Fund's
                                 assets invested in convertible securities and
                                 non-convertible income securities will vary
                                 from time to time consistent with the Fund's
                                 investment objective, changes in equity prices
                                 and changes in interest rates and other
                                 economic and market factors, although, under
                                 normal circumstances, the Fund will invest at
                                 least 50% of its managed assets in convertible
                                 securities. "Managed assets" means the total
                                 assets of the Fund (including any assets
                                 attributable to any leverage that may be
                                 outstanding) minus the sum of accrued
                                 liabilities (other than debt representing
                                 financial leverage). For this purpose, the
                                 liquidation preference on any preferred shares
                                 will not constitute a liability. The Fund
                                 invests in securities with a broad range of
                                 maturities. The average term to maturity of the
                                 Fund's securities will typically range from
                                 five to ten years. See "Investment Objective
                                 and Principal Investment
                                 Strategies -- Principal Investment Strategies."

                                 Convertible Securities.  The Fund is not
                                 limited in the percentage of its assets
                                 invested in convertible securities and
                                 investment in convertible securities forms an
                                 important part of the Fund's investment
                                 strategies. Under normal circumstances, the
                                 Fund will invest at least 50% of its managed
                                 assets in convertible securities. A convertible
                                 security is a debt security or preferred stock
                                 that is exchangeable for an equity security of
                                 the issuer at a predetermined price (the
                                 "conversion price"). Depending upon the
                                 relationship of the conversion price to the
                                 market value of the underlying security, a
                                 convertible security may trade more like an
                                 equity security than a debt instrument. See
                                 "Investment Objective and Principal Investment
                                 Strategies -- Principal Investment
                                 Strategies -- Convertible Securities."

                                 Synthetic Convertible Securities.  Calamos may
                                 also create a "synthetic" convertible security
                                 by combining separate securities that possess
                                 the two principal characteristics of a true
                                 convertible security, i.e., a fixed-income
                                 security ("fixed-income component") and the
                                 right to acquire an equity security
                                 ("convertible component"). The fixed-income
                                 component is achieved by investing in
                                 non-convertible, fixed-income securities such
                                 as bonds, preferred stocks and money market
                                 instruments. The convertible component is
                                 achieved by investing in warrants or options to
                                 buy common stock at a certain exercise price,
                                 or

                                        2


                                 options on a stock index. The Fund may also
                                 purchase synthetic securities created by other
                                 parties, typically investment banks, including
                                 convertible structured notes. Different
                                 companies may issue the fixed-income and
                                 convertible components which may be purchased
                                 separately, and at different times. The Fund's
                                 holdings of synthetic convertible securities
                                 are considered convertible securities for
                                 purposes of the Fund's policy to invest at
                                 least 50% of its managed assets in convertible
                                 securities and 80% of its managed assets in a
                                 diversified portfolio of convertible securities
                                 and non-convertible income securities. See
                                 "Investment Objective and Principal Investment

                                 Non-Convertible Income Securities.  The Fund
                                 will also invest in non-convertible income
                                 securities. The Fund's investments in non-
                                 convertible income securities may have fixed or
                                 variable principal payments and all types of
                                 interest rate and dividend payment and reset

                                 High Yield Securities.  A substantial portion
                                 of the Fund's assets may be invested in below
                                 investment grade (high yield, high risk)
                                 securities. These securities are rated Ba or
                                 lower by Moody's or BB or lower by Standard &
                                 Poor's or are unrated securities of comparable
                                 quality as determined by Calamos, the Fund's
                                 investment adviser. The Fund may invest in high
                                 yield securities of any rating. Debt securities
                                 rated below investment grade are commonly
                                 referred to as "junk bonds" and are considered
                                 speculative with respect to the issuer's
                                 capacity to pay interest and repay principal.
                                 They involve greater risk of loss, are subject
                                 to greater price volatility and are less
                                 liquid, especially during periods of economic
                                 uncertainty or change, than higher rated debt

                                 Foreign Issuers.  While the Fund primarily
                                 invests in securities of U.S. issuers, the Fund
                                 may invest up to 25% of its net assets in
                                 securities of foreign issuers, including debt
                                 and equity securities of corporate issuers and
                                 debt securities of government issuers in
                                 developed and emerging markets. A foreign
                                 issuer is a company organized under the laws of
                                 a foreign country that is principally traded in
                                 the financial markets of a foreign country. For
                                 purposes of the 25% limitation, foreign
                                 securities do not include securities
                                 represented by American Depository Receipts
                                 ("ADRs") or securities guaranteed by a U.S.

                                 Rule 144A Securities.  The Fund may invest
                                 without limit in securities that have not been
                                 registered for public sale, but that

                                 Other Securities.  Normally, the Fund invests
                                 substantially all of its assets to meet its
                                 investment objective. The Fund may invest the
                                 remainder of its assets in other securities of
                                 various types. For temporary defensive
                                 purposes, the Fund may depart from its
                                 principal investment strategies and invest part
                                 or all of its assets in securities with
                                 remaining maturities of less than one year,
                                 cash equivalents, or may hold cash. During such
                                 periods, the Fund may not be able to achieve
                                 its investment objective. See "Investment
                                 Objective and Principal Investment

USE OF LEVERAGE BY THE FUND...   The Fund may, but is not required to, use
                                 financial leverage for investment purposes. In
                                 addition to issuing Preferred Shares, the Fund
                                 may borrow money or issue debt securities such
                                 as commercial paper or notes. Throughout the
                                 prospectus, borrowing money and issuing debt
                                 securities sometimes may be collectively
                                 referred to as "Borrowings." Any Borrowings
                                 will have seniority over Preferred Shares and
                                 payments to holders of Preferred Shares in
                                 liquidation or otherwise will be subject to the
                                 prior payment of any Borrowings. As a
                                 non-fundamental policy, financial leverage (the
                                 total of Preferred Shares or other preferred
                                 shares and any Borrowings) may not exceed
                                 33 1/3% of the Fund's total assets. Since
                                 Calamos's fee is based upon a percentage of the
                                 Fund's managed assets, which include assets
                                 attributable to any outstanding leverage, the
                                 investment management fee will be higher if the
                                 Fund is leveraged and Calamos will have an
                                 incentive to be more aggressive and leverage
                                 the Fund. Calamos intends only to leverage the
                                 Fund when it believes that the potential return
                                 on such additional investments is likely to
                                 exceed the costs incurred in connection with
                                 the borrowing. See "Leverage."

RISK FACTORS SUMMARY..........   Risk is inherent in all investing. Therefore,
                                 before investing in the Preferred Shares you
                                 should consider certain risks carefully. The
                                 primary risks of investing in the Preferred
                                 Shares are:

                                 - the Fund will not be permitted to declare
                                   dividends or other distributions with respect
                                   to your Preferred Shares or redeem your
                                   Preferred Shares unless the Fund meets
                                   certain asset coverage requirements;

                                 - if you try to sell your Preferred Shares
                                   between auctions you may not be able to sell
                                   any or all of your shares or you may not be
                                   able to sell them for $25,000 per share or
                                   $25,000 per share plus accumulated dividends.
                                   If the Fund has designated a special rate
                                   period, changes in interest rates could
                                   affect the price you would receive if you
                                   sold your shares in the secondary market. You
                                   may transfer shares outside of auction only
                                   to or through a broker-dealer that has
                                   entered into an agreement with the auction
                                   agent and the Fund or other person as the
                                   Fund permits.

                                 - if an auction fails you may not be able to
                                   sell some or all of your shares;

                                 - because of the nature of the market for
                                   Preferred Shares, you may receive less than
                                   the price you paid for your shares if you
                                   sell them outside of the auction, especially
                                   when market interest rates are rising;

                                 - a rating agency could downgrade the rating
                                   assigned to the Preferred Shares, which could
                                   affect liquidity;

                                 - the Fund may be forced to redeem your shares
                                   to meet regulatory or rating agency
                                   requirements or may voluntarily redeem your
                                   shares in certain circumstances;

                                 - in extraordinary circumstances, the Fund may
                                   not earn sufficient income from its
                                   investments to pay dividends;

                                 - the Preferred Shares will be junior to any
                                   Borrowings;

                                 - any Borrowing may constitute a substantial
                                   lien and burden on the Preferred Shares by
                                   reason of its priority claim against the
                                   income of the Fund and against the net assets
                                   of the Fund in liquidation;

                                 - if the Fund leverages through Borrowings, the
                                   Fund may not be permitted to declare
                                   dividends or other distributions with respect
                                   to the Preferred Shares or purchase Preferred
                                   Shares unless at the time thereof the Fund
                                   meets certain asset coverage requirements and
                                   the payments of principal and of interest on
                                   any such Borrowings are not in default.

                                 - the value of the Fund's investment portfolio
                                   may decline, reducing the asset coverage for
                                   the Preferred Shares. See "Risk
                                   Factors -- General Risks of Investing in the
                                   Funds" below for a discussion of the general
                                   risks of the Fund's investment portfolio.

                                        5


                                 - as a result of the terrorist attacks on the
                                   World Trade Center and the Pentagon on
                                   September 11, 2001, some of the U.S.
                                   securities markets were closed for a four-day
                                   period. These terrorist attacks and related
                                   events have led to increased short-term
                                   market volatility and may have long-term
                                   effects on U.S. and world economies and
                                   markets. A similar disruption of the
                                   financial markets could impact interest
                                   rates, auctions, secondary trading, ratings,
                                   credit risk, inflation and other factors
                                   relating to securities or other financial
                                   interests.

                                 For additional information about the risks of
                                 investing in Preferred Shares and in the Fund,
                                 see "Risk Factors."

TRADING MARKET................   The Preferred Shares will not be listed on an
                                 exchange. Instead, you may buy or sell the
                                 Preferred Shares at an auction that normally is
                                 held every seven days for the Series
                                           ,           ,           and
                                           and every 28 days for the Series
                                           , by submitting orders to a
                                 broker-dealer that has entered into an
                                 agreement with the auction agent and the Trust
                                 (a "Broker-Dealer"), or to a broker-dealer that
                                 has entered into a separate agreement with a
                                 Broker-Dealer. In addition to the auctions,
                                 Broker-Dealers and other broker-dealers may
                                 maintain a secondary trading market in
                                 Preferred Shares outside of auctions, but may
                                 discontinue this activity at any time. There is
                                 no assurance that a secondary market will
                                 provide shareholders with liquidity. You may
                                 transfer shares outside of auctions only to or
                                 through a Broker-Dealer or a broker-dealer that
                                 has entered into a separate agreement with a
                                 Broker-Dealer.

                                 The table below shows the first auction date
                                 for each series of Preferred Shares and the day
                                 on which each subsequent auction will normally
                                 be held for each series of Preferred Shares.
                                 The first auction date for each series of
                                 Preferred Shares will be the business day
                                 before the dividend payment date for the
                                 initial rate period for that series of
                                 Preferred Shares. The start date for subsequent
                                 rate periods will normally be the business day
                                 following the auction date unless the
                                 then-current rate period is a special rate
                                 period or the first day of the subsequent rate
                                 period is not a business day.

DIVIDENDS AND RATE PERIODS....   The table below shows the dividend rates, the
                                 dividend payment dates and number of days for
                                 the initial rate periods on each series of
                                 Preferred Shares offered in this prospectus.
                                 For subsequent rate periods, each series of
                                 Preferred Shares will pay dividends based on a
                                 rate set at auctions, normally held every seven
                                 days in the case of Series           ,
                                           ,           and           and every
                                 28 days in the case of Series           . In
                                 most instances, dividends are payable on the
                                 first business day following the end of the
                                 rate period. The rate set at auction will not

                                 designate special rate periods of more than
                                 seven or 28 days. A requested special rate
                                 period will not be effective unless sufficient

                                 payable prior to such date must be paid in

                                 substitute rating agency that the proposed

                                 Preferred Shares. The dividend payment date for
                                 special rate periods will be set out in the

                                 Periods" and "The Auction."

RATINGS.......................   The Fund will issue Preferred Shares only if
                                 such shares have received a credit quality
                                 rating of "          " from Fitch and
                                 "          " from Moody's. These ratings are an
                                 assessment of the capacity and willingness of
                                 an issuer to pay preferred stock obligations.
                                 The ratings are not a recommendation to
                                 purchase, hold or sell those shares inasmuch as
                                 the rating does not comment as to market price
                                 or suitability for a particular investor. The
                                 ratings described above also do not address the
                                 likelihood that an owner of Preferred Shares
                                 will be able to sell such shares in an auction
                                 or otherwise. The ratings are based on current
                                 information furnished to Fitch and Moody's by
                                 the Fund and Calamos and information obtained
                                 from other sources. The ratings may be changed,
                                 suspended or withdrawn in the rating agencies'
                                 discretion as a result of changes in, or the
                                 unavailability of, such information. See
                                 "Description of Preferred Shares -- Rate Agency
                                 Guidelines and Asset Coverage."

ASSET MAINTENANCE.............   Under the Fund's Statement of Preferences for
                                 Preferred Shares (the "Statement"), which
                                 establishes and fixes the rights and
                                 preferences of the shares of each series of
                                 Preferred Shares, the Fund must maintain:

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

                                 - asset coverage of at least 200% with respect
                                   to senior securities that are stock,
                                   including the Preferred Shares.

                                 In the event that the Fund does not maintain or
                                 cure these coverage tests, some or all of the
                                 Preferred Shares will be subject to mandatory
                                 redemption. See "Description of Preferred
                                 Shares -- Redemption."

                                 Based on the composition of the Fund's
                                 portfolio as of           , 2002, the asset
                                 coverage of the Preferred Shares as measured
                                 pursuant to the 1940 Act would be approximately
                                   % if the Fund were to issue all of the
                                 Preferred Shares offered in this
                                        7


                                 Prospectus, representing approximately   % of
                                 the Fund's managed assets.

RESTRICTIONS ON DIVIDENDS,
REDEMPTION AND OTHER
  PAYMENTS....................   If the Fund issues any Borrowings that
                                 constitute senior securities representing
                                 indebtedness (as defined in the 1940 Act),
                                 under the 1940 Act, the Fund would not be
                                 permitted to declare any dividend on Preferred
                                 Shares unless, after giving effect to such
                                 dividend, asset coverage with respect to the
                                 Fund's Borrowings that constitute senior
                                 securities representing indebtedness, if any,
                                 is at least 200%. In addition, the Fund would
                                 not be permitted to declare any distribution on
                                 or purchase or redeem Preferred Shares unless,
                                 after giving effect to such distribution,
                                 purchase or redemption, asset coverage with
                                 respect to the Fund's Borrowings that
                                 constitute senior securities representing
                                 indebtedness, if any, is at least 300%.
                                 Dividends or other distributions on or
                                 redemptions or purchases of Preferred Shares
                                 would also be prohibited at any time that an
                                 event of default under the Borrowings, if any,
                                 has occurred and is continuing. See
                                 "Description of Preferred Shares --
                                 Restrictions on Dividend, Redemption and Other
                                 Payments."

REDEMPTION....................   The Fund may be required to redeem shares if,
                                 for example, the Fund does not meet an asset
                                 coverage ratio required by law or to correct a
                                 failure to meet a rating agency guideline in a
                                 timely manner. The Fund voluntarily may redeem
                                 Preferred Shares under certain conditions. See
                                 "Description of Preferred Shares -- Redemption"
                                 and "Description of Preferred Shares  -- Rating
                                 Agency Guidelines and Asset Coverage."

LIQUIDATION PREFERENCE........   The liquidation preference for shares of each
                                 series of Preferred Shares will be $25,000 per
                                 share plus accumulated but unpaid dividends, if
                                 any, whether or not declared. See "Description
                                 of Preferred Shares -- Liquidation."

VOTING RIGHTS.................   The holders of preferred shares, including
                                 Preferred Shares, voting as a separate class,
                                 have the right to elect at least two trustees
                                 of the Fund at all times. The Board of Trustees
                                 will determine to which class or classes the
                                 Trustees elected by the holders of Preferred
                                 Shares will be assigned, and the holders of the
                                 Preferred Shares will only be entitled to elect
                                 the Trustees so designated as being elected by
                                 the holders of the Preferred Shares, when their
                                 term will have expired and such Trustees
                                 appointed by the holders of Preferred Shares
                                 will be allocated as evenly as possible among
                                 the classes of Trustees. Holders of Preferred
                                 Shares also have the right to elect a majority
                                 of the trustees in the event that two years'
                                 dividends on the preferred shares are unpaid.
                                 In each case, the remaining trustees will be
                                 elected by holders of common shares and
                                 preferred shares, including Preferred Shares,
                                 voting together as a single class. The holders
                                 of preferred shares, including Preferred
                                 Shares, will vote as a separate class or
                                 classes on certain other matters as required
                                 under the Fund's Agreement and Declaration of
                                 Trust, the Investment Company Act of 1940 (the
                                 "Investment Company Act") and Delaware law. See
                                 "Description of Preferred Shares -- Voting
                                 Rights," and "Certain Provisions in the
                                 Agreement and Declaration of Trust."

FEDERAL INCOME TAXES..........   Distributions with respect to the Preferred
                                 Shares will generally be subject to U.S.
                                 federal income taxation. Because the Fund's

                                        8


                                 portfolio income will consist principally of
                                 (i) income from securities that are not
                                 eligible for a dividends received deduction,
                                 (ii) capital gain and (iii) interest income,
                                 corporate investors in the Preferred Shares may
                                 only be entitled to the 70% dividends received
                                 deduction on a portion of the Fund's qualifying
                                 distributions. The Internal Revenue Service
                                 ("IRS") currently requires that a regulated
                                 investment company, which has two or more
                                 classes of stock, allocate to each such class
                                 proportionate amounts of each type of its
                                 income (such as ordinary income and capital
                                 gain) based upon the percentage of total
                                 dividends distributed to each class for the tax
                                 year. Accordingly, the Fund intends each year
                                 to allocate ordinary income dividends and
                                 capital gain dividends between its Common
                                 Shares and the Preferred Shares in proportion
                                 to the total dividends paid to each class
                                 during or with respect to such year. See "Tax
                                 Matters."

performance of the Fund from the commencement of the Fund's investment

                                USE OF PROCEEDS

     The Fund estimates the net proceeds of the offering of Preferred Shares
after payment of sales load and offering expenses, will be $          . The Fund
will invest the net proceeds of the offering in accordance with the Fund's
investment objective and policies as stated below. It is presently anticipated
that the Fund will be able to invest substantially all of the net proceeds in
securities that meet these investment objectives and policies within      months
after completion of this offering. Pending such investment, the Fund anticipates
that all or a portion of the proceeds will be invested in U.S. government
securities or high grade, short-term money market instruments. If necessary, the
Fund may also purchase, as temporary investments, securities of other open- or

                             THE FUND'S INVESTMENTS

INVESTMENT OBJECTIVE

     The Fund's investment objective is to provide total return, through a
combination of capital appreciation and current income. The Fund makes no
assurance that it will realize its objective. See "Risk Factors."

PRINCIPAL INVESTMENT STRATEGIES

     Under normal circumstances, the Fund will invest at least 80% of its
managed assets in a diversified portfolio of convertible securities and
non-convertible income securities. This is a non-fundamental policy and may be
changed by the Board of Trustees of the Fund provided that shareholders are
provided with at least 60 days' prior written notice of any change as required
by the rules under the 1940 Act. The portion of the Fund's assets invested in
convertible securities and non-convertible income securities will vary from time
to time consistent with the Fund's investment objective, changes in equity
prices and changes in interest rates and other economic and market factors,
although, under normal circumstances, the Fund will invest at least 50% of its
managed assets in convertible securities. The Fund invests in securities with a
broad range of maturities. The average term to maturity of the Fund's securities
typically will range from five to ten years.

     Convertible Securities.  The Fund is not limited in the percentage of its
assets invested in convertible securities, and investment in convertible
securities forms an important part of the Fund's investment strategies. A
convertible security is a debt security or preferred stock that is exchangeable
for an equity security of the issuer at a predetermined price. Depending upon
the relationship of the conversion price to the market value of the underlying
security, a convertible security may trade more like an equity security than a
debt instrument.

                                        13


     Calamos typically applies a four-step approach when buying and selling
convertible securities for the Fund, which includes:

          1. Evaluating the default risk of the convertible security using
     traditional credit analysis;

          2. Analyzing the convertible's underlying common stock to determine
     its capital appreciation potential;

          3. Assessing the risk/return potential of the convertible security;
     and

          4. Evaluating the convertible security's impact on the overall
     composition of the Fund and its diversification strategy.

     In analyzing the appreciation potential of the underlying common stock and
the default risk of the convertible security, Calamos generally considers the
issuer's:

     - financial soundness;

     - ability to make interest and dividend payments;

     - earnings and cash-flow forecast; and

     - quality of management.

     Synthetic Convertible Securities.  Calamos may also create a "synthetic"
convertible security by combining separate securities that possess the two
principal characteristics of a true convertible security, i.e., a fixed-income
security ("fixed-income component") and the right to acquire an equity security
("convertible component"). The fixed-income component is achieved by investing
in non-convertible, fixed-income securities such as bonds, preferred stocks and
money market instruments. The convertible component is achieved by investing in
warrants or options to buy common stock at a certain exercise price, or options
on a stock index. The Fund may also purchase synthetic securities created by
other parties, typically investment banks, including convertible structured
notes. Different companies may issue the fixed-income and convertible
components, which may be purchased separately and at different times. The Fund's
holdings of synthetic convertible securities are considered convertible
securities for purposes of the Fund's policy to invest at least 50% of its
managed assets in convertible securities and 80% of its managed assets in a
diversified portfolio of convertible securities and non-convertible income
securities.

     Non-Convertible Income Securities.  The Fund will also invest in
non-convertible income securities. The Fund's investments in non-convertible
income securities may have fixed or variable principal payments and all types of
interest rate and dividend payment and reset terms, including fixed rate,
adjustable rate, zero coupon, contingent, deferred, payment in kind and auction
rate features.

     High Yield Securities.  A substantial portion of the Fund's assets may be
invested in below investment grade (high yield, high risk) securities. The high
yield securities in which the Fund invests are rated Ba or lower by Moody's or
BB or lower by Standard & Poor's or are unrated but determined by Calamos to be
of comparable quality. The Fund may, but currently does not intend to, purchase
distressed securities that are in default or the issuers of which are in
bankruptcy. Debt securities rated below investment grade are commonly referred
to as "junk bonds" and are considered speculative with respect to the issuer's
capacity to pay interest and repay principal. Below investment grade debt
securities involve greater risk of loss, are subject to greater price volatility
and are less liquid, especially during periods of economic uncertainty or
change, than higher rated debt securities.

     Preferred Shares.  The Fund may invest in preferred shares. The preferred
shares in which the Fund typically will invest will be convertible securities.
Preferred shares are equity securities, but they have many characteristics of
fixed income securities, such as a fixed dividend payment rate and/or a
liquidity preference over the issuer's common shares. However, because preferred
shares are equity securities, they may be more susceptible to risks
traditionally associated with equity investments than the Fund's fixed income
securities.

                                        14


     Foreign Securities.  While the Fund primarily invests in securities of U.S.
issuers, the Fund may invest up to 25% of its net assets in securities of
foreign issuers, including debt and equity securities of corporate issuers and
debt securities of government issuers in developed and emerging markets. A
foreign issuer is a company organized under the laws of a foreign country that
is principally traded in the financial markets of a foreign country. For
purposes of the 25% limitation, foreign securities do not include securities
represented by American Depository Receipts ("ADRs") or securities guaranteed by
a U.S. person.

     Rule 144A Securities.  The Fund may invest without limit in securities that
have not been registered for public sale, but that are eligible for purchase and
sale by certain qualified institutional buyers ("Rule 144A Securities").

     REITs.  The Fund may invest in real estate investment trusts ("REITs").
REITs primarily invest in income producing real estate or real estate related
loans or interests. REITs are generally classified as equity REITs, mortgage
REITs or a combination of equity and mortgage REITs. Equity REITs invest the
majority of their assets directly in real property and derive income primarily
from the collection of rents. Equity REITs can also realize capital gains by
selling properties that have appreciated in value. Mortgage REITs invest the
majority of their assets in real estate mortgages and derive income from the
collection of interest payments. REITs are not taxed on income distributed to
shareholders provided they comply with the applicable requirements of the
Internal Revenue Code of 1986, as amended (the "Code"). The Fund will indirectly
bear its proportionate share of any management and other expenses paid by REITs
in which it invests in addition to the expenses paid by the Fund. Debt
securities issued by REITs are, for the most part, general and unsecured
obligations and are subject to risks associated with REITs.

     U.S. Government Securities.  U.S. government securities in which the Fund
invests include debt obligations of varying maturities issued by the U.S.
Treasury or issued or guaranteed by an agency or instrumentality of the U.S.
government, including the Federal Housing Administration, Federal Financing
Bank, Farmers Home Administration, Export-Import Bank of the United States,
Small Business Administration, Government National Mortgage Association
("GNMA"), General Services Administration, Central Bank for Cooperatives,
Federal Farm Credit Banks, Federal Home Loan Banks, Federal Home Loan Mortgage
Corporation ("FHLMC"), Federal National Mortgage Association ("FNMA"), Maritime
Administration, Tennessee Valley Authority, District of Columbia Armory Board,
Student Loan Marketing Association, Resolution Fund Corporation and various
institutions that previously were or currently are part of the Farm Credit
System (which has been undergoing reorganization since 1987). Some U.S.
government securities, such as U.S. Treasury bills, Treasury notes and Treasury
bonds, which differ only in their interest rates, maturities and times of
issuance, are supported by the full faith and credit of the United States.
Others are supported by: (i) the right of the issuer to borrow from the U.S.
Treasury, such as securities of the Federal Home Loan Banks; (ii) the
discretionary authority of the U.S. government to purchase the agency's
obligations, such as securities of the FNMA; or (iii) only the credit of the
issuer. No assurance can be given that the U.S. government will provide
financial support in the future to U.S. government agencies, authorities or
instrumentalities that are not supported by the full faith and credit of the
United States. Securities guaranteed as to principal and interest by the U.S.
government, its agencies, authorities or instrumentalities include: (i)
securities for which the payment of principal and interest is backed by an
irrevocable letter of credit issued by the U.S. government or any of its
agencies, authorities or instrumentalities; and (ii) participations in loans
made to non-U.S. governments or other entities that are so guaranteed. The
secondary market for certain of these participations is limited and, therefore,
may be regarded as illiquid.

     Zero Coupon Securities.  The securities in which the Fund invests may
include zero coupon securities, which are debt obligations that are issued or
purchased at a significant discount from face value. The discount approximates
the total amount of interest the security will accrue and compound over the
period until maturity or the particular interest payment date at a rate of
interest reflecting the market rate of the security at the time of issuance.
Zero coupon securities do not require the periodic payment of interest. These
investments benefit the issuer by mitigating its need for cash to meet debt
service, but generally require a higher rate of return to attract investors who
are willing to defer receipt of cash. These
                                        15


investments may experience greater volatility in market value than U.S.
government securities that make regular payments of interest. The Fund accrues
income on these investments for tax and accounting purposes, which is
distributable to shareholders and which, because no cash is received at the time
of accrual, may require the liquidation of other portfolio securities to satisfy
the Fund's distribution obligations, in which case the Fund will forgo the
purchase of additional income producing assets with these funds. Zero coupon
U.S. government securities include STRIPS and CUBES, which are issued by the
U.S. Treasury as component parts of U.S. Treasury bonds and represent scheduled
interest and principal payments on the bonds.

     Investments in Equity Securities.  Consistent with its objective, the Fund
may invest in equity securities. Equity securities, such as common stock,
generally represent an ownership interest in a company. While equity securities
have historically generated higher average returns than fixed income securities,
equity securities have also experienced significantly more volatility in those
returns. An adverse event, such as an unfavorable earnings report, may depress
the value of a particular equity security held by the Fund. Also, the price of
equity securities, particularly common stocks, are sensitive to general
movements in the stock market. A drop in the stock market may depress the price
of equity securities held by the Fund.

     Other Investment Companies.  The Fund may invest in the securities of other
investment companies to the extent that such investments are consistent with the
Fund's investment objective and policies and permissible under the 1940 Act.
Under the 1940 Act, the Fund may not acquire the securities of other domestic or
non-U.S. investment companies if, as a result, (1) more than 10% of the Fund's
total assets would be invested in securities of other investment companies, (2)
such purchase would result in more than 3% of the total outstanding voting
securities of any one investment company being held by the Fund, or (3) more
than 5% of the Fund's total assets would be invested in any one investment
company. These limitations do not apply to the purchase of shares of any
investment company in connection with a merger, consolidation, reorganization or
acquisition of substantially all the assets of another investment company.

     The Fund, as a holder of the securities of other investment companies, will
bear its pro rata portion of the other investment companies' expenses, including
advisory fees. These expenses are in addition to the direct expenses of the
Fund's own operations.

     Defensive and Temporary Investments.  Under unusual market or economic
conditions or for temporary defensive purposes, the Fund may invest up to 100%
of its total assets in securities issued or guaranteed by the U.S. government or
its instrumentalities or agencies, certificates of deposit, bankers' acceptances
and other bank obligations, commercial paper rated in the highest category by a
nationally recognized statistical rating organization or other fixed income
securities deemed by Calamos to be consistent with a defensive posture, or may
hold cash. The yield on such securities may be lower than the yield on lower
rated fixed income securities.

     Repurchase Agreements.  The Fund may enter into repurchase agreements with
broker-dealers, member banks of the Federal Reserve System and other financial
institutions. Repurchase agreements are arrangements under which the Fund
purchases securities and the seller agrees to repurchase the securities within a
specific time and at a specific price. The repurchase price is generally higher
than the Fund's purchase price, with the difference being income to the Fund.
The counterparty's obligations under the repurchase agreement are collateralized
with U.S. Treasury and/or agency obligations with a market value of not less
than 100% of the obligations, valued daily. Collateral is held by the Fund's
custodian in a segregated, safekeeping account for the benefit of the Fund.
Repurchase agreements afford the Fund an opportunity to earn income on
temporarily available cash at low risk. In the event of commencement of
bankruptcy or insolvency proceedings with respect to the seller of the security
before repurchase of the security under a repurchase agreement, the Fund may
encounter delay and incur costs before being able to sell the security. Such a
delay may involve loss of interest or a decline in price of the security. If the
court characterizes the transaction as a loan and the Fund has not perfected a
security interest in the security, the Fund may be required to return the
security to the seller's estate and be treated as an unsecured

                                        16


creditor of the seller. As an unsecured creditor, the Fund would be at risk of
losing some or all of the principal and interest involved in the transaction.

     Lending of Portfolio Securities.  The Fund may lend portfolio securities to
registered broker-dealers or other institutional investors deemed by Calamos to
be of good standing under agreements which require that the loans be secured
continuously by collateral in cash, cash equivalents or U.S. Treasury bills
maintained on a current basis at an amount at least equal to the market value of
the securities loaned. The Fund continues to receive the equivalent of the
interest or dividends paid by the issuer on the securities loaned as well as the
benefit of an increase and the detriment of any decrease in the market value of
the securities loaned and would also receive compensation based on investment of
the collateral. The Fund would not, however, have the right to vote any
securities having voting rights during the existence of the loan, but would call
the loan in anticipation of an important vote to be taken among holders of the
securities or of the giving or withholding of consent on a material matter
affecting the investment.

     As with other extensions of credit, there are risks of delay in recovery or
even loss of rights in the collateral should the borrower of the securities fail
financially. At no time would the value of the securities loaned exceed 33 1/3%
of the value of the Fund's total assets.

     Portfolio Turnover.  It is the policy of the Fund not to engage in trading
for short-term profits although portfolio turnover rate is not considered a
limiting factor in the execution of investment decisions for the Fund.

                                    LEVERAGE

     The Fund may issue preferred shares, including Preferred Shares, or borrow
or issue short-term debt securities to increase its assets available for
investment. The Fund is authorized to issue preferred shares, borrow or issue
debt obligations. As a non-fundamental policy, such preferred shares, including
Preferred Shares, or borrowing may not exceed 33 1/3% of the Fund's total
assets. Before issuing such preferred shares to increase its assets available
for investment, the Fund must have received confirmation from Moody's and Fitch
or any substitute rating agency that the proposed issuance will not adversely
affect such rating agency's then-current rating on the Preferred Shares. The
Fund generally will not issue preferred shares or borrow unless Calamos expects
that the Fund will achieve a greater return on such borrowed funds than the
additional costs the Fund incurs as a result of such borrowing. The Fund also
may borrow money as a temporary measure for extraordinary or emergency purposes,
including the payment of dividends and the settlement of securities transactions
which otherwise might require untimely dispositions of the Fund's holdings. When
the Fund leverages its assets, the fees paid to Calamos for investment
management services will be higher than if the Fund did not borrow because
Calamos's fees are calculated based on the Fund's managed assets, which include
the proceeds of the issuance of preferred shares or any outstanding borrowings.
Consequently, the Fund and Calamos may have differing interests in determining
whether to leverage the Fund's assets.

     The Fund's use of leverage is premised upon the expectation that the Fund's
preferred share dividends or borrowing cost will be lower than the return the
Fund achieves on its investments with the proceeds of the issuance of preferred
shares or borrowing. Such difference in return may result from the Fund's higher
credit rating or the short-term nature of its borrowing compared to the
long-term nature of its investments. Since the total assets of the Fund
(including the assets obtained from leverage) will be invested in the higher
yielding portfolio investments or portfolio investments with the potential for
capital appreciation, the holders of common shares will be the beneficiaries of
the incremental return. Should the differential between the underlying assets
and cost of leverage narrow, the incremental return "pick up" will be reduced.
Furthermore, if long-term rates rise or the Fund otherwise incurs losses on its
investments, the Fund's net asset value attributable to its common shares will
reflect the decline in the value of portfolio holdings resulting therefrom.

     To the extent the income or capital appreciation derived from securities
purchased with funds received from leverage exceeds the cost of leverage, the
Fund's return to common shareholders will be

                                        17


greater than if leverage had not been used. Conversely, if the income or capital
appreciation from the securities purchased with such funds is not sufficient to
cover the cost of leverage or if the Fund incurs capital losses, the return of
the Fund to common shareholders will be less than if leverage had not been used.
Calamos may determine to maintain the Fund's leveraged position if it expects
that the long-term benefits to the Fund's common shareholders of maintaining the
leveraged position will outweigh the current reduced return. Capital raised
through the issuance of preferred shares or borrowing will be subject to
dividend payments or interest costs that may or may not exceed the income and
appreciation on the assets purchased. The Fund also may be required to maintain
minimum average balances in connection with borrowings or to pay a commitment or
other fee to maintain a line of credit; either of these requirements will
increase the cost of borrowing over the stated interest rate.

     The Fund may be subject to certain restrictions on investments imposed by
guidelines of one or more nationally recognized rating organizations which may
issue ratings for the preferred shares or short-term debt instruments issued by
the Fund. These guidelines may impose asset coverage or portfolio composition
requirements that are more stringent than those imposed by the 1940 Act. Certain
types of borrowings may result in the Fund being subject to covenants in credit
agreements, including those relating to asset coverage, borrowing base and
portfolio composition requirements and additional covenants. The Fund may also
be required to pledge its assets to the lenders in connection with certain types
of borrowing. Calamos does not anticipate that these covenants or restrictions
will adversely affect its ability to manage the Fund's portfolio in accordance
with the Fund's investment objective and policies. Due to these covenants or
restrictions, the Fund may be forced to liquidate investments at times and at
prices that are not favorable to the Fund, or the Fund may be forced to forgo
investments that Calamos otherwise views as favorable.

     If and to the extent that the Fund employs leverage will depend on many
factors, the most important of which are investment outlook, market conditions
and interest rates.

                                        18


                                  RISK FACTORS

     Risk is inherent in all investing. Investing in any investment company
security involves risk, including the risk that you may receive little or no
return on your investment or that you may lose part or all of your investment.
Therefore, before investing you should consider carefully the following risks
that you assume when you invest in Preferred Shares.

RISKS OF INVESTING IN PREFERRED SHARES

     Interest Rate Risk.  The Fund issues Preferred Shares, which pay dividends
based on short-term interest rates. The Fund purchases convertible securities,
high yield securities and other securities that pay dividends that are based on
the performance of the issuing companies, and/or that pay interest, based on
longer term yields. These dividends and interest payments are typically,
although not always higher than short-term interest rates. Such dividends and
interest payments, as well as long-term and short-term interest rates,
fluctuate. If short-term interest rates rise, dividend rates on the Preferred
Shares may rise so that the amount of dividends paid to shareholders of
Preferred Shares exceeds the income from the portfolio securities. Because
income from the Fund's entire investment portfolio (not just the portion of the
portfolio purchased with the proceeds of the Preferred Shares offering) is
available to pay dividends on the Preferred Shares, dividend rates on the
Preferred Shares would need to greatly exceed the Fund's net portfolio income
before the Fund's ability to pay dividends on the Preferred Shares would be
jeopardized. If long-term interest rates rise, this could negatively impact the
value of the Fund's investment portfolio, reducing the amount of assets serving
as asset coverage for the Preferred Shares.

     Auction Risk.  You may not be able to sell your Preferred Shares at an
auction if the auction fails; that is, if there are more Preferred Shares
offered for sale than there are buyers for those shares. Also, if you place hold
orders (orders to retain Preferred Shares) at an auction only at a specified
rate, and that bid rate exceeds the rate set at the auction, you will not retain
your Preferred Shares. Additionally, if you buy shares or elect to retain shares
without specifying a rate below which you would not wish to continue to hold
those shares, and the auction sets a below-market rate, you may receive a lower
rate of return on your shares than the market rate. Finally, the dividend
periods for the Preferred Shares may be changed by the Fund, subject to certain
conditions with notice to the holders of Preferred Shares, which could also
affect the liquidity of your investment. See "Description of Preferred Shares"
and "The Auction -- Auction Procedures."

     Secondary Market Risk.  If you try to sell your Preferred Shares between
auctions, you may not be able to sell any or all of your shares, or you may not
be able to sell them for $25,000 per share or $25,000 per share plus accumulated
dividends. If the Fund has designated a special dividend period (a rate period
other than seven days in the case of Series           ,           ,
and           and 28 days in the case of Series           , changes in interest
rates could affect the price you would receive if you sold your shares in the
secondary market. Broker-dealers that maintain a secondary trading market for
Preferred Shares are not required to maintain that market, and the Fund is not
required to redeem shares either if an auction or an attempted secondary market
sale fails because of a lack of buyers. Preferred Shares are not listed on a
stock exchange or the NASDAQ stock market. You may transfer shares outside of
auctions only to or through a Broker-Dealer that has entered into an agreement
with the Fund's auction agent,           , and the Fund or such other persons as
the Fund permits. If you sell your Preferred Shares to a broker-dealer between
auctions, you may receive less than the price you paid for them, especially if
market interest rates have risen since the last auction. Accumulated Preferred
Shares dividends, however, should at least partially compensate for the
increased market interest rates.

     Ratings and Asset Coverage Risk.  Although it is expected that Moody's will
assign a rating of           to the Preferred Shares and Fitch will assign a
rating of           to the Preferred Shares, such ratings do not eliminate or
necessarily mitigate the risks of investing in Preferred Shares. Moody's or
Fitch could downgrade its rating of the Preferred Shares or withdraw its rating
of the Preferred Shares at any time, which may make your shares less liquid at
an auction or in the secondary market. If Moody's or Fitch downgrades the
Preferred Shares, the Fund may alter its portfolio or redeem Preferred Shares in
an

                                        19


effort to improve the rating, although there is no assurance that it will be
able to do so to the extent necessary to restore the prior rating. If the Fund
fails to satisfy the asset coverage ratios discussed under "Description of
Preferred Shares -- Rating Agency Guidelines and Asset Coverage," the Fund will
be required to redeem a sufficient number of Preferred Shares in order to return
to compliance with the asset coverage ratios. The Fund may be required to redeem
Preferred Shares at a time when it is not advantageous for the Fund to make such
redemption or to liquidate portfolio securities in order to have available cash
for such redemption. The Fund may voluntarily redeem Preferred Shares under
certain circumstances in order to meet asset maintenance tests. Although a sale
of substantially all the assets of the Fund or the merger of the Fund into
another entity would require the approval of the holders of the Preferred Shares
voting as a separate class as discussed under "Description of the Preferred
Shares -- Voting Rights," a sale of substantially all of the assets of the Fund
or the merger of the Fund with or into another entity would not be treated as a
liquidation of the Fund nor require that the Fund redeem the Preferred Shares,
in whole or in part, provided that the Fund continued to comply with the asset
coverage ratios discussed under "Description of Preferred Shares -- Rating
Agency Guidelines and Asset Coverage." See "Description of Preferred
Shares -- Rating Agency Guidelines and Asset Coverage" for a description of the
asset maintenance tests the Fund must meet.

     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 your Preferred
Shares investment or the income from that investment will be worth less in the
future. As inflation occurs, the real value of the Preferred Shares and
distributions declines. In an inflationary period, however, it is expected that,
through the auction process, Preferred Shares dividend rates would increase,
tending to offset this risk.

     Income Risk.  The Fund's income is based primarily on the income it earns
from its investments, which vary widely over the short- and long-term. If the
Fund's income drops, over time the Fund's ability to make dividend payments with
respect to the Preferred Shares may be impaired. See "-- General Risks of
Investing in the Fund" below for the general risks affecting the Fund.

     Decline in Net Asset Value Risk.  A material decline in the Fund's net
asset value may impair the Fund's ability to maintain required levels of asset
coverage. For a description of risks affecting the Fund, see "-- General Risks
of Investing in the Fund" below.

     Payment Restrictions.  The Fund is prohibited from declaring, paying or
making any dividends or distributions on Preferred Shares unless it satisfies
certain conditions. See "Description of Preferred Shares -- Restrictions on
Dividend, Redemption and Other Payments." The Fund is also prohibited from
declaring, paying or making any dividends or distributions on common shares
unless it satisfies certain conditions. These prohibitions on the payment of
dividends or distributions might impair the Fund's ability to maintain its
qualification as a regulated investment company for federal income tax purposes.
The Fund intends, however, to redeem Preferred Shares if necessary to comply
with the asset coverage requirements. There can be no assurance, however, that
such redemptions can be effected in time to permit the Fund to distribute its
income as required to maintain its qualification as a regulated investment
company under the Code. See "Tax Matters -- Federal Income Tax Treatment of the
Fund" in the statement of additional information.

     Leverage Risk.  The Fund uses financial leverage for investment purposes.
In addition to issuing Preferred Shares, the Fund may make further use of
financial leverage through borrowing, including the issuance of commercial paper
or notes. As a non-fundamental policy, financial leverage (including Preferred
Shares and Borrowings) may not exceed 33 1/3% of the Funds' total assets. The
Fund may also borrow funds (a) in connection with a loan made by a bank or other
party that is privately arranged and not intended to be publicly distributed or
(b) in an amount equal to up to 5% of its total assets for temporary purposes
only.

     If the Fund issues any senior securities representing indebtedness (as
defined in the 1940 Act), under the requirements of the 1940 Act, the value of
the Fund's total assets, less all liabilities and indebtedness of the Fund not
represented by such senior securities, must be at least equal, immediately after
any such
                                        20


senior securities representing indebtedness, to 300% of the aggregate value of
such senior securities. Upon the issuance of Preferred Shares, the value of the
Fund's total assets, less all liabilities and indebtedness of the Fund not
represented by senior securities must be at least equal, immediately after the
issuance of the Preferred Shares, to 200% of the aggregate value of any senior
securities and the Preferred Shares.

     If the Fund seeks an investment grade rating from one or more nationally
recognized statistical rating organizations for any commercial paper and notes
(which the Fund expects to do if it issues any such commercial paper or notes),
asset coverage or portfolio composition provisions in addition to and more
stringent than those required by the 1940 Act may be imposed in connection with
the issuance of such a rating. In addition, restrictions may be imposed on
certain investment practices in which the Fund may otherwise engage. Any lender
with respect to Borrowings by the Fund may require additional asset coverage and
portfolio composition provisions as well as restrictions on the Fund's
investment practices.

     The money borrowed pursuant to any Borrowings may constitute a substantial
lien and burden on the Preferred Shares by reason of their prior claim against
the income of the Fund and against the net assets of the Fund in liquidation.
The Fund may not be permitted to declare dividends or other distributions,
including with respect to Preferred Shares or purchase or redeem shares,
including Preferred Shares unless (i) at the time thereof the Fund meets certain
asset coverage requirements and (ii) there is no event of default under any
Borrowings, that is continuing. See "Description of Preferred
Shares -- Restrictions on Dividend, Redemption and Other Payments." In the event
of a default under any Borrowings, the lenders may have the right to cause a
liquidation of the collateral (i.e., sell portfolio securities) and if any such
default is not cured, the lenders may be able to control the liquidation as
well.

     The Fund reserves the right at any time, if it believes that market
conditions are appropriate, to increase its level of debt or other senior
securities to maintain or increase the Fund's current level of leverage to the
extent permitted by the 1940 Act and existing agreements between the Fund and
third parties. However, as a non-fundamental policy, financial leverage (the
total of Preferred Shares or other preferred shares and any Borrowings) may not
exceed 33 1/3% of the Fund's total assets.

     Because the fee paid to Calamos will be calculated on the basis of managed
assets, the fee will be higher when leverage is utilized, giving Calamos an
incentive to utilize leverage.

GENERAL RISKS OF INVESTING IN THE FUND

     Limited Operating History.  The Fund is a recently organized closed-end
management investment company with a limited operating history.

     Convertible Securities.  The value of a convertible security is influenced
by both the yield of non-convertible securities of comparable issuers and by the
value of the underlying common stock. The value of a convertible security viewed
without regard to its conversion feature (i.e., strictly on the basis of its
yield) is sometimes referred to as its "investment value." The investment value
of a convertible security tends to decline as prevailing interest rate levels
increase. Conversely, a convertible's investment value increases as prevailing
interest rate levels decline. However, the convertible's market value will also
be influenced by its "conversion value," which is the market value of the
underlying common stock that would be obtained if the convertible security were
converted. The conversion value of a convertible security tends to increase as
the price of the underlying common stock increases, and decrease as the price of
the underlying common stock decreases. As the market price of the underlying
common stock declines such that the conversion value is substantially below the
investment value of the convertible security, the price of the convertible
security tends to be influenced more by the yield of the convertible security.
Thus, it may not decline in price to the same extent as the underlying common
stock. If the market price of the underlying common stock increases to a point
where the conversion value approximates or exceeds the investment value, the
price of the convertible security tends to be influenced more by the market
price of the underlying common stock. In the event of a liquidation of the
issuing company, holders of convertible securities would be paid before the
company's common stock holders. Consequently, the issuer's convertible
securities entail less risk than its common stock.

                                        21


     Synthetic Convertible Securities.  The value of a synthetic convertible
security will respond differently to market fluctuations than a convertible
security because a synthetic convertible is composed of two or more separate
securities, each with its own market value. In addition, if the value of the
underlying common stock or the level of the index involved in the convertible
component falls below the exercise price of the warrant or option, the warrant
or option may lose all value.

     High Yield Securities.  Investment in high yield securities involves
substantial risk of loss. Below investment grade debt securities or comparable
unrated securities are commonly referred to as "junk bonds" and are considered
predominantly speculative with respect to the issuer's ability to pay interest
and principal and are susceptible to default or decline in market value due to
adverse economic and business developments. The market values for high yield
securities tend to be very volatile, and these securities are less liquid than
investment grade debt securities. For these reasons, your investment in the Fund
is subject to the following specific risks:

     - increased price sensitivity to changing interest rates and to a
       deteriorating economic environment;

     - greater risk of loss due to default or declining credit quality;

     - adverse company specific events are more likely to render the issuer
       unable to make interest and/or principal payments; and

     - if a negative perception of the high yield market develops, the price and
       liquidity of high yield securities may be depressed. This negative
       perception could last for a significant period of time.

     Debt securities rated below investment grade are speculative with respect
to the capacity to pay interest and repay principal in accordance with the terms
of such securities. A rating of C from Moody's means that the issue so rated can
be regarded as having extremely poor prospects of ever attaining any real
investment standing. Standard & Poor's assigns a rating of C to issues that are
currently highly vulnerable to nonpayment, and the C rating may be used to cover
a situation where a bankruptcy petition has been filed or similar action taken,
but payments on the obligation are being continued (a C rating is also assigned
to a preferred stock issue in arrears on dividends or sinking fund payments, but
that is currently paying). See the statement of additional information for a
description of Moody's and Standard & Poor's ratings.

     Adverse changes in economic conditions are more likely to lead to a
weakened capacity of a high yield issuer to make principal payments and interest
payments than an investment grade issuer. The principal amount of high yield
securities outstanding has proliferated in the past decade as an increasing
number of issuers have used high yield securities for corporate financing. An
economic downturn could severely affect the ability of highly leveraged issuers
to service their debt obligations or to repay their obligations upon maturity.
Similarly, down-turns in profitability in specific industries could adversely
affect the ability of high yield issuers in those industries to meet their
obligations. The market values of lower quality debt securities tend to reflect
individual developments of the issuer to a greater extent that do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. Factors having an adverse impact on the market value of lower
quality securities may have an adverse effect on the Fund's net asset value and
the market value of its common shares. In addition, the Fund may incur
additional expenses to the extent it is required to seek recovery upon a default
in payment of principal or interest on its portfolio holdings. In certain
circumstances, the Fund may be required to foreclose on an issuer's assets and
take possession of its property or operations. In such circumstances, the Fund
would incur additional costs in disposing of such assets and potential
liabilities from operating any business acquired.

     The secondary market for high yield securities may not be as liquid as the
secondary market for more highly rated securities, a factor which may have an
adverse effect on the Fund's ability to dispose of a particular security when
necessary to meet its liquidity needs. There are fewer dealers in the market for
high yield securities than investment grade obligations. The prices quoted by
different dealers may vary significantly and the spread between the bid and
asked price is generally much larger than for higher quality instruments. Under
adverse market or economic conditions, the secondary market for high yield
                                        22


securities could contract further, independent of any specific adverse changes
in the condition of a particular issuer, and these instruments may become
illiquid. As a result, the Fund could find it more difficult to sell these
securities or may be able to sell the securities only at prices lower than if
such securities were widely traded. Prices realized upon the sale of such lower
rated or unrated securities, under these circumstances, may be less than the
prices used in calculating the Fund's net asset value.

     Since investors generally perceive that there are greater risks associated
with lower quality debt securities of the type in which the Fund may invest a
portion of its assets, the yields and prices of such securities may tend to
fluctuate more than those for higher rated securities. In the lower quality
segments of the debt securities market, changes in perceptions of issuers'
creditworthiness tend to occur more frequently and in a more pronounced manner
than do changes in higher quality segments of the debt securities market,
resulting in greater yield and price volatility.

     If the Fund invests in high yield securities that are rated C or below, the
Fund will incur significant risk in addition to the risks associated with
investments in high yield securities and corporate loans. Distressed securities
frequently do not produce income while they are outstanding. The Fund may
purchase distressed securities that are in default or the issuers of which are
in bankruptcy. The Fund may be required to bear certain extraordinary expenses
in order to protect and recover its investment.

     Interest Rate Risk.  Fixed income securities, including high yield
securities, are subject to certain common risks, including:

     - if interest rates go up, the value of debt securities in the Fund's
       portfolio generally will decline;

     - during periods of declining interest rates, the issuer of a security may
       exercise its option to prepay principal earlier than scheduled, forcing
       the Fund to reinvest in lower yielding securities. This is known as call
       or prepayment risk. Debt securities frequently have call features that
       allow the issuer to repurchase the security prior to its stated maturity.
       An issuer may redeem an obligation if the issuer can refinance the debt
       at a lower cost due to declining interest rates or an improvement in the
       credit standing of the issuer; and

     - during periods of rising interest rates, the average life of certain
       types of securities may be extended because of slower than expected
       principal payments. This may lock in a below market interest rate,
       increase the security's duration (the estimated period until the security
       is paid in full) and reduce the value of the security. This is known as
       extension risk.

     REITS.  Investing in REITs involves certain unique risks in addition to
those risks associated with investing in the real estate industry in general. An
equity REIT may be affected by changes in the value of the underlying properties
owned by the REIT. A mortgage REIT may be affected by changes in interest rates
and the ability of the issuers of its portfolio mortgages to repay their
obligations. REITs are dependent upon the skills of their managers and are not
diversified. REITs are generally dependent upon maintaining cash flows to repay
borrowings and to make distributions to shareholders and are subject to the risk
of default by lessees or borrowers. REITs whose underlying assets are
concentrated in properties used by a particular industry, such as health care,
are also subject to risks associated with such industry.

     REITs (especially mortgage REITs) are also subject to interest rate risks.
When interest rates decline, the value of a REIT's investment in fixed rate
obligations can be expected to rise. Conversely, when interest rates rise, the
value of a REIT's investment in fixed rate obligations can be expected to
decline. If the REIT invests in adjustable rate mortgage loans the interest
rates on which are reset periodically, yields on a REIT's investments in such
loans will gradually align themselves to reflect changes in market interest
rates. This causes the value of such investments to fluctuate less dramatically
in response to interest rate fluctuations than would investments in fixed rate
obligations.

     REITs may have limited financial resources, may trade less frequently and
in a limited volume and may be subject to more abrupt or erratic price movements
than larger company securities. Historically, REITs have been more volatile in
price than the larger capitalization stocks included in Standard & Poor's 500
Stock Index.

                                        23


     Illiquid Investments.  The Fund may invest without limit in illiquid
securities. The Fund may also invest without limitation in securities that have
not been registered for public sale, but that are eligible for purchase and sale
by certain qualified institutional buyers. Although many of the Rule 144A
Securities in which the Fund invests may be, in the view of Calamos, liquid, if
qualified institutional buyers are unwilling to purchase these Rule 144A
Securities, they may be illiquid. Illiquid securities may be difficult to
dispose of at a fair price at the times when the Fund believes it is desirable
to do so. The market price of illiquid securities generally is more volatile
than that of more liquid securities, which may adversely affect the price that
the Fund pays for or recovers upon the sale of illiquid securities. Illiquid
securities are also more difficult to value and Calamos's judgment may play a
greater role in the valuation process. Investment of the Fund's assets in
illiquid securities may restrict the Fund's ability to take advantage of market
opportunities. The risks associated with illiquid securities may be particularly
acute in situations in which the Fund's operations require cash and could result
in the Fund borrowing to meet its short-term needs or incurring losses on the
sale of illiquid securities.

     Foreign Securities.  Investments in non-U.S. issuers may involve unique
risks compared to investing in securities of U.S. issuers. These risks are more
pronounced to the extent that the Fund invests a significant portion of its
non-U.S. investments in one region or in the securities of emerging market
issuers. These risks may include:

     - less information about non-U.S. issuers or markets may be available due
       to less rigorous disclosure or accounting standards or regulatory
       practices;

     - many non-U.S. markets are smaller, less liquid and more volatile. In a
       changing market, Calamos may not be able to sell the Fund's portfolio
       securities at times, in amounts and at prices it considers reasonable;

     - adverse effect of currency exchange rates or controls on the value of the
       Fund's investments;

     - the economies of non-U.S. countries may grow at slower rates than
       expected or may experience a downturn or recession;

     - economic, political and social developments may adversely affect the
       securities markets; and

     - withholding and other non-U.S. taxes may decrease the Fund's return.

     There may be less publicly available information about non-U.S. markets and
issuers than is available with respect to U.S. securities and issuers. Non-U.S.
companies generally are not subject to accounting, auditing and financial
reporting standards, practices and requirements comparable to those applicable
to U.S. companies. The trading markets for most non-U.S. securities are
generally less liquid and subject to greater price volatility than the markets
for comparable securities in the United States. The markets for securities in
certain emerging markets are in the earliest stages of their development. Even
the markets for relatively widely traded securities in certain non-U.S. markets,
including emerging market countries, may not be able to absorb, without price
disruptions, a significant increase in trading volume or trades of a size
customarily undertaken by institutional investors in the United States.
Additionally, market making and arbitrage activities are generally less
extensive in such markets, which may contribute to increased volatility and
reduced liquidity.

     Economies and social and political climate in individual countries may
differ unfavorably from the United States. Non-U.S. economies may have less
favorable rates of growth of gross domestic product, rates of inflation,
currency valuation, capital reinvestment, resource self-sufficiency and balance
of payments positions. Many countries have experienced substantial, and in some
cases extremely high, rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates have had, and may continue to have, very
negative effects on the economies and securities markets of certain emerging
countries. Unanticipated political or social developments may also affect the
values of the Fund's investments and the availability to the Fund of additional
investments in such countries.

     Currency Risk.  The value of the securities denominated or quoted in
foreign currencies may be adversely affected by fluctuations in the relative
currency exchange rates and by exchange control
                                        24


regulations. The Fund's investment performance may be negatively affected by a
devaluation of a currency in which the Fund's investments are denominated or
quoted. Further, the Fund's investment performance may be significantly
affected, either positively or negatively, by currency exchange rates because
the U.S. dollar value of securities denominated or quoted in another currency
will increase or decrease in response to changes in the value of such currency
in relation to the U.S. dollar.

     Management Risk.  Calamos' judgment about the attractiveness, relative
value or potential appreciation of a particular sector, security or investment
strategy may prove to be incorrect.

     Antitakeover Provisions.  The Fund's Agreement and Declaration of Trust and
By-laws include provisions that could limit the ability of other entities or
persons to acquire control of the Fund or to change the composition of its Board
of Trustees. Such provisions could limit the ability of shareholders to sell
their shares at a premium over prevailing market prices by discouraging a third
party from seeking to obtain control of the Fund. These provisions include
staggered terms of office for the Trustees, advance notice requirements for
shareholder proposals, and super-majority voting requirements for certain
transaction with affiliates, open-ending the Fund or a merger, asset sale or
similar transaction.

     Recent Developments.  As a result of the terrorist attacks on the World
Trade Center and the Pentagon on September 11, 2001, some of the U.S. securities
markets were closed for a four-day period. These terrorist attacks and related
events have led to increased short-term market volatility and may have long-term
effects on U.S. and world economies and markets. A similar disruption of the
financial markets could impact interest rates, auctions, secondary trading,
ratings, credit risk, inflation and other factors relating to securities or
other financial interests.

                             MANAGEMENT OF THE FUND

TRUSTEES AND OFFICERS

     The Fund's Board of Trustees provides broad supervision over the affairs of
the Fund. The officers of the Fund are responsible for the Fund's operations.
There are seven Trustees of the Fund, three of whom are "interested persons" of
the Trust (as defined in the 1940 Act) and four of whom are not "interested
persons." The names and business addresses of the trustees and officers of the
Fund and their principal occupations and other affiliations during the past five
years are set forth under "Management of the Fund" in the statement of
additional information.

INVESTMENT ADVISER

     The Fund's investments are managed by Calamos, 1111 E. Warrenville Road,
Naperville, IL. On           , 2002 Calamos managed approximately $     billion
in assets of individuals and institutions. Calamos is a wholly-owned subsidiary
of Holdings. Holdings is controlled by John P. Calamos, who has been engaged in
the investment advisory business since 1977.

INVESTMENT MANAGEMENT AGREEMENT

     Subject to the overall authority of the Board of Trustees, Calamos
regularly provides the Fund with investment research, advice and supervision and
furnishes continuously an investment program for the Fund. In addition, Calamos
furnishes for use of the Fund such office space and facilities as the Fund may
require for its reasonable needs and supervises the business and affairs of the
Fund and provides the following other services on behalf of the Fund and not
provided by persons not a party to the investment management agreement: (a)
preparing or assisting in the preparation of reports to and meeting materials
for the Trustees; (b) supervising, negotiating contractual arrangements with, to
the extent appropriate, and monitoring the performance of, accounting agents,
custodians, depositories, transfer agents and pricing agents, accountants,
attorneys, printers, underwriters, brokers and dealers, insurers and other
persons in any capacity deemed to be necessary or desirable to Fund operations;
(c) assisting in the preparation and making of filings with the Commission and
other regulatory and self-regulatory organizations, including, but not limited
to, preliminary and definitive proxy materials, amendments to the Fund's
registration statement on Form N-2 and semi-annual reports on Form N-SAR; (d)
overseeing the tabulation of proxies by the Fund's transfer agent; (e) assisting
in the preparation and filing of the Fund's federal, state and local tax
returns; (f) assisting in the preparation and filing of the Fund's federal
excise tax return pursuant to Section 4982 of the Code; (g) providing assistance
with investor and public relations matters; (h) monitoring the valuation of
portfolio securities and the calculation of net asset value; (i) monitoring the
registration of shares of beneficial interest of the Fund under applicable
federal and state securities laws; (j) maintaining or causing to be maintained
for the Fund all books, records and reports and any other information required
under the 1940 Act, to the extent that such books, records and reports and other
information are not maintained by the Fund's custodian or other agents of the
Fund; (k) assisting in establishing the accounting policies of the Fund; (l)
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 the Fund's other agents as necessary in connection therewith;
(m) reviewing the Fund's bills; (n) 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 (o)
otherwise assisting the Fund as it may reasonably request in the conduct of the
Fund's business, subject to the direction and control of the Trustees.

     Under the investment management agreement, the Fund pays to Calamos a fee
based on the average weekly managed assets that is accrued daily and paid on a
monthly basis. The fee paid by the Fund is at the annual rate of 0.80% of
managed assets. Because the fees paid to Calamos are determined on the basis

                                        26


of the Fund's managed assets, Calamos's interest in determining whether to
leverage the Fund may differ from the interests of the Fund and its common
shareholders.

     Under the terms of its investment management agreement, except for the
services and facilities provided by Calamos as set forth therein, the Fund
assumes and pays all expenses for all other Fund operations and activities and
shall reimburse Calamos for any such expenses incurred by Calamos. The expenses
borne by the Fund include, without limitation: (a) organization expenses of the
Fund (including out-of-pocket expenses, but not including Calamos' overhead or
employee costs); (b) fees payable to Calamos; (c) legal expenses; (d) auditing
and accounting expenses; (e) maintenance of books and records that are required
to be maintained by the Fund's custodian or other agents of the Fund; (f)
telephone, telex, facsimile, postage and other communications expenses; (g)
taxes and governmental fees; (h) fees, dues and expenses incurred by the Fund in
connection with membership in investment company trade organizations and the
expense of attendance at professional meetings of such organizations; (i) fees
and expenses of accounting agents, custodians, subcustodians, transfer agents,
dividend disbursing agents and registrars; (j) payment for portfolio pricing or
valuation services to pricing agents, accountants, bankers and other
specialists, if any; (k) expenses of preparing share certificates; (l) expenses
in connection with the issuance, offering, distribution, sale, redemption or
repurchase of securities issued by the Fund; (m) expenses relating to investor
and public relations provided by parties other than Calamos; (n) expenses and
fees of registering or qualifying shares of beneficial interest of the Fund for
sale; (o) interest charges, bond premiums and other insurance expenses; (p)
freight, insurance and other charges in connection with the shipment of the
Fund's portfolio securities; (q) the compensation and all expenses (specifically
including travel expenses relating to Fund business) of Trustees, officers and
employees of the Fund who are not affiliated persons of Calamos; (r) brokerage
commissions or other costs of acquiring or disposing of any portfolio securities
of the Fund; (s) expenses of printing and distributing reports, notices and
dividends to shareholders; (t) expenses of preparing and setting in type,
printing and mailing prospectuses and statements of additional information of
the Fund and supplements thereto; (u) costs of stationery; (v) any litigation
expenses; (w) indemnification of Trustees and officers of the Fund; (x) costs of
shareholders' and other meetings; (y) interest on borrowed money, if any; and
(z) the fees and other expenses of listing the Fund's shares on the New York
Stock Exchange or any other national stock exchange.

     For the first eight years of the Fund's operations, Calamos has
contractually agreed to waive its management fee in the annual amounts, and for
the time periods, set forth below:

PORTFOLIO MANAGER

     John P. Calamos and Nick P. Calamos are responsible for managing the
portfolio of the Fund. During the past five years, John P. Calamos has been
president of Calamos and Calamos Financial Services, Inc. ("CFS"), an affiliate
of Calamos, and Nick P. Calamos has been senior executive vice president of
Calamos and CFS.

                                        27


ADMINISTRATOR

     Under the terms of an administration agreement among the Fund, Calamos and
Princeton Administrators, L.P. (the "Administrator"), an affiliate of Merrill
Lynch, Pierce, Fenner & Smith Incorporated (the "Administration Agreement"), the
Administrator performs or arranges for the performance of certain administrative
services necessary for the operation of the Fund, including, but not limited to,
maintaining certain of the books and records of the Fund, preparing certain
reports and other documents required by U.S. federal securities laws and
regulations, responding to inquiries from Fund shareholders, calculating and
distributing for publication the net asset value of the Fund's shares and
providing the Fund with certain administrative office facilities. For the
services rendered and the facilities furnished, Calamos (and not the Fund) pays
the Administrator a monthly fee at the annual rate of 0.125% of the Fund's
average weekly managed assets, subject to a monthly minimum fee of $12,500. The
Administration Agreement will continue in effect until terminated by any party
upon 60 days' prior written notice.

                        DESCRIPTION OF PREFERRED SHARES

     The following is a brief description of the terms of the Preferred Shares.
For the complete terms of the Preferred Shares, please refer to the detailed
description of the Preferred Shares in the Statement of Preferences for
Preferred Shares (the "Statement") attached as Appendix A to the statement of
additional information.

GENERAL

     The Fund's Agreement and Declaration of Trust authorizes the issuance of an
unlimited number of preferred shares, no par value per share, in one or more
classes or series with rights as determined by the Board of Trustees without the
approval of common shareholders. The Statement currently authorizes the issuance
of           Preferred Shares, Series           , and           Preferred
Shares, Series           . All Preferred Shares will have a liquidation
preference of $25,000 per share, plus an amount equal to accumulated but unpaid
dividends (whether or not earned or declared).

     The Preferred Shares of each series will rank on parity with any other
series of Preferred Shares and any other series of preferred shares of the Fund
as to the payment of dividends and the distribution of assets upon liquidation.
Each Preferred Share carries one vote on matters on which Preferred Shares can
be voted. The Preferred Shares, when issued by the Fund and paid for pursuant to
the terms of this prospectus, will be fully paid and non-assessable and will
have no preemptive, exchange or conversion rights. Any Preferred Shares
repurchased or redeemed by the Fund will be classified as authorized and
unissued Preferred Shares. The Board of Trustees may by resolution classify or
reclassify any authorized and unissued Preferred Shares from time to time by
setting or changing the preferences, rights, voting powers, restrictions,
limitations as to dividends, qualifications or terms or conditions of redemption
of such shares. The Preferred Shares will not be subject to any sinking fund,
but will be subject to mandatory redemption under certain circumstances
described below.

DIVIDENDS AND RATE PERIODS

     The following is a general description of dividends and rate periods for
the Preferred Shares.

     Rate Periods.  The initial rate period and rate for each series of
Preferred Shares is as set forth below:



SERIES   INITIAL RATE PERIOD   INITIAL DIVIDEND RATE
------   -------------------   ---------------------
                         


     Any subsequent rate periods of a series of Preferred Shares will generally
be seven or 28 days. The Fund, subject to certain conditions, may change the
length of subsequent rate periods by designating them as special rate periods.
See "-- Designation of Special Rate Periods" below.

     Dividend Payment Dates.  Dividends on each series of Preferred Shares will
be payable, when, as and if declared by the Board of Trustees, out of legally
available funds in accordance with the Agreement and Declaration of Trust, the
Statement and applicable law. Dividends are scheduled to be paid for each series
as follows:



         INITIAL DIVIDEND   SUBSEQUENT DIVIDEND
SERIES     PAYMENT DATE        PAYMENT DATES
------   ----------------   -------------------
                      


     Dividend periods generally will begin on the first business day after an
auction. If dividends are payable on a day that is not a business day, then
dividends will generally be payable on the next day if such day is a business
day, or as otherwise specified in the Statement. In addition, the Fund may
specify different dividend payment dates for any special rate period of more
than seven days in the case of the Series           ,           ,           and
          Preferred Shares and more than 28 days in the case

                                        29


of Series           , provided that such dates shall be set forth in the notice
of special rate period relating to such special rate period.

     Dividends will be paid through the Depository Trust Company ("DTC") on each
dividend payment date. The dividend payment date will normally be the first
business day after the dividend period ends. DTC, in accordance with its current
procedures, is expected to distribute dividends received from the auction agent
in same-day funds on each dividend payment date to agent members (members of DTC
that will act on behalf of existing or potential holders of Preferred Shares).
These agent members are in turn expected to distribute such dividends to the
persons for whom they are acting as agents. However, each of the current
Broker-Dealers has indicated to the Fund that dividend payments will be
available in same-day funds on each dividend payment date to customers that use
a Broker-Dealer or a Broker-Dealer's designee as agent member.

     Calculation of Dividend Payment.  The Fund computes the dividends per share
payable on Preferred Shares by multiplying the applicable rate in effect by a
fraction. The numerator of this fraction will normally be the number of days in
the rate period and the denominator will normally be 360. This rate is then
multiplied by $25,000 to arrive at the dividends per share.

     Dividends on Preferred Shares will accumulate from the date of their
original issue, which is           , 2002. For each dividend payment period
after the initial rate period, the dividend will be the dividend rate determined
at auction. The dividend rate that results from an auction will not be greater
than the maximum applicable rate described below.

     The maximum applicable rate for any standard rate period will be the
applicable percentage (set forth in the table below) of the applicable "AA"
Composite Commercial Paper Rate. In the case of a special rate period, the
maximum applicable rate will be specified by the Fund in the notice of the
special rate period for such dividend payment period. The applicable percentage
will be determined based on the lower of the credit rating or ratings assigned
to the Preferred Shares by Fitch and Moody's. If Fitch and Moody's or both do
not make such rating available, the rate will be determined by reference to
equivalent ratings issued by a substitute rating agency.



   CREDIT RATINGS FOR PREFERRED SHARES      APPLICABLE
   ------------------------------------     PERCENTAGE:
        MOODY'S             FITCH         NO NOTIFICATION
   -----------------   ----------------   ---------------
                                    
    Aa3 or higher      AA- or higher           150%
      A3 to A1            A- to A+             200%
    Baa3 to Baa1        BBB- to BBB+           225%
     Below Baa3          Below BBB-            275%


     Prior to each dividend payment date, the Fund is required to deposit with
the auction agent sufficient funds for the payment of declared dividends. The
failure to make such deposit will not result in the cancellation of any auction.
The Fund does not intend to establish any reserves for the payment of dividends.

     Restrictions on Dividend, Redemption and Other Payments.  Under the 1940
Act, the Fund may not (i) declare any dividend with respect to the Preferred
Shares if, at the time of such declaration (and after giving effect thereto),
asset coverage with respect to the Fund's Borrowings that are senior securities
representing indebtedness (as defined in the 1940 Act), would be less than 200%
(or such other percentage as may in the future be specified in or under the 1940
Act as the minimum asset coverage for senior securities representing
indebtedness of a closed-end investment company as a condition of declaring
dividends on its preferred shares) or (ii) declare any other distribution on the
Preferred Shares or purchase or redeem Preferred Shares if at the time of the
declaration (and after giving effect thereto), asset coverage with respect to
the Fund's senior securities representing indebtedness would be less than 300%
(or such other percentage as may in the future be specified in or under the 1940
Act as the minimum asset coverage for senior securities representing
indebtedness of a closed-end investment company as a condition of declaring
distributions, purchases or redemptions of its shares of beneficial

                                        30


interest). "Senior securities representing indebtedness" generally means any
bond, debenture, note or similar obligation or instrument constituting a
security (other than shares of beneficial interest) and evidencing indebtedness
and could include the Fund's obligations under any Borrowings. For purposes of
determining asset coverage for senior securities representing indebtedness in
connection with the payment of dividends or other distributions on or purchases
or redemptions of stock, the term "senior security" does not include any
promissory note or other evidence of indebtedness issued in consideration of any
loan, extension or renewal thereof, made by a bank or other person and privately
arranged, and not intended to be publicly distributed. The term "senior
security" also does not include any such promissory note or other evidence of
indebtedness in any case where such a loan is for temporary purposes only and in
an amount not exceeding 5% of the value of the total assets of the Fund at the
time when the loan is made; a loan is presumed under the 1940 Act to be for
temporary purposes if it is repaid within 60 days and is not extended or
renewed; otherwise it is presumed not to be for temporary purposes. For purposes
of determining whether the 200% and 300% asset coverage requirements described
above apply in connection with dividends or distributions on or purchases or
redemptions of Preferred Shares, such asset coverages may be calculated on the
basis of values calculated as of a time within 48 hours (not including Sundays
or holidays) next preceding the time of the applicable determination.

     In addition, a declaration of a dividend or other distribution on or
purchase or redemption of Preferred Shares may be prohibited (i) at any time
when an event of default under any Borrowings has occurred and is continuing; or
(ii) after giving effect to such declaration, the Fund would not have eligible
portfolio holdings with an aggregated discounted value at least equal to any
asset coverage requirements associated with such Borrowings; or (iii) the Fund
has not redeemed the full amount of Borrowings, if any, required to be redeemed
by any provision for mandatory redemption.

     While any of the Preferred Shares are outstanding, the Fund generally may
not declare, pay or set apart for payment, any dividend or other distribution in
respect of its common shares (other than in additional shares of common stock or
rights to purchase common stock) or repurchase any of its common shares (except
by conversion into or exchange for shares of the Fund ranking junior to the
Preferred Shares as to the payment of dividends and the distribution of assets
upon liquidation) unless each of the following conditions has been satisfied:

     - In the case of Moody's coverage requirements, immediately after such
       transaction, the aggregate Moody's Coverage Value (i.e., the aggregate
       value of the Fund's portfolio discounted according to Moody's criteria)
       would be equal to or greater than the Preferred Shares Basic Maintenance
       Amount (i.e., the amount necessary to pay all outstanding obligations of
       the Fund with respect to the Preferred Shares, any preferred stock
       outstanding expenses for the next 90 days and any other liabilities of
       the Fund) (see "Rating Agency Guidelines" below);

     - In the case of Fitch's coverage requirements, immediately after such
       transaction, the Aggregate Fitch Value (i.e., the aggregate value of the
       Fund's portfolio discounted according to Fitch criteria) would be equal
       to or greater than the Preferred Shares Basic Maintenance Amount;

     - Immediately after such transaction, the 1940 Act Preferred Shares Asset
       Coverage (as defined in this Prospectus under "Rating Agency Guidelines"
       below) is met;

     - Full cumulative dividends on the Preferred Shares due on or prior to the
       date of the transaction have been declared and paid or have been declared
       and sufficient funds for the payment thereof deposited with the auction
       agent; and

     - The Fund has redeemed the full number of Preferred Shares required to be
       redeemed by any provision for mandatory redemption contained in the
       Statement.

     The Fund generally will not declare, pay or set apart for payment any
dividend on any shares of the Fund ranking as to the payment of dividends on a
parity with Preferred Shares unless the Fund has declared and paid or
contemporaneously declares and pays full cumulative dividends on the Preferred
Shares through its most recent dividend payment date. However, if the Fund has
not paid dividends in full on the Preferred Shares through the most recent
dividend payment date or upon any shares of the Fund
                                        31


ranking, as to the payment of dividends, on a parity with Preferred Shares
through their most recent respective dividend payment dates, the amount of
dividends declared per share on Preferred Shares and such other class or series
of shares will in all cases bear to each other the same ratio that accumulated
dividends per share on the Preferred Shares and such other class or series of
shares bear to each other.

     Designation of Special Rate Periods.  The Fund may, in certain situations,
[at its sole option,] declare a special rate period. Prior to declaring a
special rate period, the Fund will give notice (a "notice of special rate
period") to the auction agent and to each Broker-Dealer. The notice will state
that the next succeeding rate period for the Preferred Shares will be a number
of days as specified in such notice. The Fund may not designate a special rate
period unless sufficient clearing bids were made in the most recent auction. In
addition, full cumulative dividends, any amounts due with respect to mandatory
redemptions and any additional dividends payable prior to such date must be paid
in full or deposited with the auction agent. The Fund also must have received
confirmation from Fitch and Moody's or any substitute rating agency that the
proposed special rate period will not adversely affect such agency's
then-current rating on the Preferred Shares. The Fund also must have portfolio
securities with a discounted value at least equal to the Preferred Share
Maintenance Amount. A notice of special rate period also will specify whether
the Preferred Shares will be subject to optional redemption during such special
rate period and, if so, the redemption, premium, if any, required to be paid by
the Fund in connection with such optional redemption.

VOTING RIGHTS

     Except as noted below, the Fund's common shares and Preferred Shares have
equal voting rights of one vote per share and vote together as a single class.
In elections of trustees, the holders of Preferred Shares, as a separate class,
vote to elect two trustees. The Board of Trustees will determine to which class
or classes the Trustees elected by the holders of Preferred Shares will be
assigned and the holders of the Preferred Shares shall only be entitled to elect
the Trustees so designated as being elected by the holders of the Preferred
Shares, when their term shall have expired and such Trustees appointed by the
holders of Preferred Shares will be allocated as evenly as possible among the
classes of Trustees. The holders of the common shares and holders of Preferred
Shares vote together as a single class to elect the remaining trustees. In
addition, during any period ("Voting Period") in which the Fund has not paid
dividends on the Preferred Shares in an amount equal to two full years
dividends, the holders of Preferred Shares, voting as a single class, are
entitled to elect (in addition to the two trustees set forth above) the smallest
number of additional directors as is necessary to ensure that a majority of the
trustees has been elected by the holders of Preferred Shares. The holders of
Preferred Shares will continue to have these rights until all dividends in
arrears have been paid or otherwise provided for.

     In an instance when the Fund has not paid dividends as set forth in the
immediately preceding paragraph, the terms of office of all persons who are
trustees of the Fund at the time of the commencement of a Voting Period will
continue, notwithstanding the election by the holders of the Preferred Shares of
the number of trustees that such holders are entitled to elect. The persons
elected by the holders of the Preferred Shares, together with the incumbent
trustees, will constitute the duly elected trustees of the Fund. When all
dividends in arrears on the Preferred Shares have been paid or provided for, the
terms of office of the additional trustees elected by the holders of the
Preferred Shares will terminate.

     So long as any of the Preferred Shares are outstanding, the Fund will not,
without the affirmative vote of the holders of a majority of the outstanding
Preferred Shares, (i) institute any proceedings to be adjudicated bankrupt or
insolvent, or consent to the institution of bankruptcy or insolvency proceedings
against it, or file a petition seeking or consenting to reorganization or relief
under any applicable federal or state law relating to bankruptcy or insolvency,
or consent to the appointment of a receiver, liquidator, assignee, trustee,
sequestrator (or other similar official) of the Fund or a substantial part of
its property, or make any assignment for the benefit of creditors, or, except as
may be required by applicable law, admit in writing its inability to pay its
debts generally as they become due or take any corporate action in furtherance
of any such action; (ii) create, incur or suffer to exist, or agree to create,
incur or suffer to
                                        32


exist, or consent to cause or permit in the future (upon the happening of a
contingency or otherwise) the creation, incurrence or existence of any material
lien, mortgage, pledge, charge, security interest, security agreement,
conditional sale or trust receipt or other material encumbrance of any kind upon
any of the Fund's assets as a whole, except (A) liens the validity of which are
being contested in good faith by appropriate proceedings, (B) liens for taxes
that are not then due and payable or that can be paid thereafter without
penalty, (C) liens, pledges, charges, security interests, security agreements or
other encumbrances arising in connection with any indebtedness senior to the
Preferred Shares, (D) liens, pledges, charges, security interests, security
agreements or other encumbrances arising in connection with any indebtedness
permitted under clause (iii) below and (E) liens to secure payment for services
rendered including, without limitation, services rendered by the Fund's Paying
Agent and the auction agent; or (iii) create, authorize, issue, incur or suffer
to exist any indebtedness for borrowed money or any direct or indirect guarantee
of such indebtedness for borrowed money, except the Fund may borrow as may be
permitted by the Fund's investment restrictions; provided, however, that
transfers of assets by the Fund subject to an obligation to repurchase will not
be deemed to be indebtedness for purposes of this provision to the extent that
after any such transaction the Fund has eligible assets with an aggregate
discounted value at least equal to the Preferred Shares Basic Maintenance Amount
as of the immediately preceding valuation date.

     In addition, the affirmative vote of the holders of a majority, as defined
in the 1940 Act, of the outstanding Preferred Shares is required to approve any
plan of reorganization (as such term is used in the 1940 Act) adversely
affecting such shares or any action requiring a vote of security holders of the
Fund under Section 13(a) of the 1940 Act, including, among other things, changes
in the Fund's fundamental investment restrictions described under "Investment
Restrictions" in the Statement of Additional Information and changes in the
Fund's subclassification as a closed-end investment company.

     The affirmative vote of the holders of a majority, as defined in the 1940
Act, of the outstanding Preferred Shares of any series, voting separately from
any other series, shall be required with respect to any matter that materially
and adversely affects the rights, preferences, or powers of that series in a
manner different from that of other series or classes of the Fund's shares of
beneficial interest. For purposes of the foregoing, no matter will be deemed to
adversely affect any right, preference or power unless such matter (i) alters or
abolishes any preferential right of such series; (ii) creates, alters or
abolishes any right in respect of redemption of such series; or (iii) creates or
alters (other than to abolish) any restriction on transfer applicable to such
series. The vote of holders of any series described in this paragraph will in
each case be in addition to a separate vote of the requisite percentage of
common shares and/or preferred shares necessary to authorize the action in
question.

     The common shares and the Preferred Shares also will vote separately to the
extent otherwise required under Delaware law or the 1940 Act as in effect from
time to time. The class votes of holders of Preferred Shares described above
will in each case be in addition to any separate vote of the requisite
percentage of common shares and Preferred Shares, voting together as a single
class, necessary to authorize the action in question.

     For purpose of any right of the holders of Preferred Shares to vote on any
matter, whether the right is created by the Agreement and Declaration of Trust,
by statute or otherwise, a holder of a preferred share is not entitled to vote
and the Preferred Shares will not be deemed to be outstanding for the purpose of
voting or determining the number of Preferred Shares required to constitute a
quorum, if prior to or concurrently with a determination of the Preferred Shares
entitled to vote or of Preferred Shares deemed outstanding for quorum purposes,
as the case may be, a notice of redemption was given in respect of those
Preferred Shares and sufficient Deposit Securities (as defined in the Statement
of Additional Information) for the redemption of those Preferred Shares were
deposited.

RATING AGENCY GUIDELINES

     The Fund is required under Fitch and Moody's guidelines to maintain assets
having in the aggregate a discounted value at least equal to the Preferred
Shares Basic Maintenance Amount (as defined below).

                                        33


Fitch and Moody's 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 the rating agency). The Fitch and Moody's guidelines also impose
certain diversification requirements on the Fund's overall portfolio. The
"Preferred Shares Basic Maintenance Amount" includes the sum of (i) the
aggregate liquidation preference of the Preferred Shares then outstanding, (ii)
the total principal of any senior debt (plus accrued and projected dividends),
(iii) certain Fund expenses and (iv) certain other current liabilities.

     The Fund also is required under rating agency guidelines to maintain, with
respect to the Preferred Shares, as of the last business day of each month in
which Preferred Shares are outstanding, asset coverage of at least 200% with
respect to senior securities that are shares of the Fund, including the
Preferred 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
that are shares of a closed-end investment company as a condition of declaring
dividends on its Common Shares) ("1940 Act Preferred Shares Asset Coverage").
Fitch and Moody's have agreed that the auditors must certify once per quarter
the asset coverage test on a date randomly selected by the auditors. Based on
the Fund's assets and liabilities as of           , 2002, and assuming the
issuance of all Preferred Shares offered hereby and the use of the proceeds as
intended, the 1940 Act Preferred Shares Asset Coverage with respect to Preferred
Shares would be computed as follows:


                                                                         
Value of Fund assets less liabilities not constituting
  senior securities.........................................          $
                                                                =              =         %
Senior securities representing indebtedness plus liquidation
  value of the preferred shares.............................          $


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

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

     The Board of Trustees may amend the definition of Maximum Rate to increase
the percentage amount by which the Reference Rate is multiplied to determine the
Maximum Rate without the vote or consent of the holders of Preferred Shares,
including each series, or any other stockholder of the Fund, but only with
confirmation from each Rating Agency, and after consultation with the
Broker-Dealers, provided that immediately following any such increase the Fund
could meet the Preferred Shares Basic Maintenance Amount Test.

     As described by Fitch and Moody's, the Preferred Shares rating is an
assessment of the capacity and willingness of the Fund to pay Preferred Shares'
obligations. The ratings on the Preferred Shares are not recommendations to
purchase, hold or sell the Preferred Shares, inasmuch as the ratings do not
comment as to market price or suitability for a particular investor. The rating
agency guidelines also do not address the likelihood that an owner of the
Preferred Shares will be able to sell such shares in an auction or otherwise.
The ratings are based on current information furnished to Fitch and Moody's by
the Fund and Calamos 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.

                                        34


     The rating agency guidelines will apply to the Preferred Shares only so
long as such rating agency is rating these shares. The Fund will pay fees to
Fitch and Moody's for rating the Preferred Shares.

REDEMPTION

     Mandatory Redemption.  If the Fund does not timely cure a failure to (1)
maintain a discounted value of its portfolio equal to the Preferred Shares Basic
Maintenance Amount, (2) maintain the 1940 Act Preferred Shares Asset Coverage,
or (3) file a required certificate related to asset coverage on time, the
Preferred Shares will be subject to mandatory redemption out of funds legally
available therefor in accordance with the Statement 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 Preferred Shares necessary to restore the required discounted
value or the 1940 Act Preferred Shares Asset Coverage, as the case may be.

     In determining the number of Preferred Shares required to be redeemed in
accordance with the foregoing, the Fund will allocate the number of shares
required to be redeemed to satisfy the Preferred Shares Basic Maintenance Amount
or the 1940 Act Preferred Shares Asset Coverage, as the case may be, pro rata
among the Preferred Shares of the Fund and any other preferred stock of the
Fund, subject to redemption or retirement. If fewer than all outstanding shares
of any series are, as a result, to be redeemed, the Fund may redeem such shares
by lot or other method that it deems fair and equitable.

     Optional Redemption.  To the extent permitted under the 1940 Act and
Delaware law, the Fund at its option may without the consent of the holders of
Preferred Shares, redeem Preferred Shares having a dividend period of one year
or less, in whole or in part, on the business day after the last day of such
dividend period upon not less than 15 calendar days and not more than 40
calendar days prior notice. The optional redemption price per share will be
$25,000 per share, plus an amount equal to accumulated but unpaid dividends
thereon (whether or not earned or declared) to the date fixed for redemption.
Preferred Shares having a dividend period of more than one year are redeemable
at the option of the Fund, in whole or in part, prior to the end of the relevant
dividend period, subject to any specific redemption provisions, which may
include the payment of redemption premiums to the extent required under any
applicable specific redemption provisions. The Fund will not make any optional
redemption unless, after giving effect thereto, (i) the Fund has available
certain deposit securities with maturities 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 the Preferred
Shares by reason of the redemption of the Preferred Shares on such date fixed
for the redemption and (ii) the Fund has eligible assets with an aggregate
discounted value at least equal to the Preferred Shares Basic Maintenance
Amount.

     Notwithstanding the foregoing, Preferred Shares may not be redeemed at the
option of the Fund unless all dividends in arrears on the outstanding Preferred
Shares, and any other outstanding preferred shares, have been or are being
contemporaneously paid or set aside for payment. This would not prevent the
lawful purchase or exchange offer for Preferred Shares made on the same terms to
holders of all outstanding preferred shares.

LIQUIDATION

     Subject to the rights of holders of any series or class or classes of
shares ranking on a parity with Preferred Shares with respect to the
distribution of assets upon liquidation of the Fund, upon a liquidation of the
Fund, whether voluntary or involuntary, the holders of Preferred Shares 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 is 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 by the Fund, but
excluding the interest thereon) accumulated but unpaid to and including the date
of final distribution in same-day funds in connection with the liquidation of
the Fund. After the payment to the holders of Preferred Shares of the full
preferential amounts

                                        35


provided for as described herein, the holders of Preferred Shares as such will
have no right or claim to any of the remaining assets of the Fund.

     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 other
entity nor the merger or consolidation of any other entity into or with the
Fund, will be a liquidation, whether voluntary or involuntary, for the purposes
of the foregoing paragraph.

                                  THE AUCTION

GENERAL

     The Statement provides that, except as otherwise described in this
prospectus, the applicable rate for the Preferred Shares for each rate period
after the initial rate period will be the rate that results from an auction
conducted as set forth in the Statement and summarized below. In such an
auction, persons determine to hold or offer to sell or, based on dividend rates
bid by them, offer to purchase or sell Preferred Shares. See the Statement
included in the statement of additional information for a more complete
description of the auction process.

     Auction Agency Agreement.  The Fund will enter into an auction agency
agreement with the auction agent (currently,           ) which provides, among
other things, that the auction agent will follow the auction procedures to
determine the applicable rate for Preferred Shares, so long as the applicable
rate for Preferred Shares is to be based on the results of an auction.

     The auction agent may terminate the auction agency agreement upon notice to
the Fund no earlier than 60 days after the delivery of 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 has entered into such an
agreement with a successor auction agent.

     Broker-Dealer Agreements.  Each auction requires the participation of one
or more Broker-Dealers. The auction agent will enter into agreements with
several Broker-Dealers selected by the Fund, which provide for the participation
of those Broker-Dealers in auctions for Preferred Shares.

     The auction agent will pay to each Broker-Dealer after each auction from
funds provided by the Fund, a service charge at the annual rate of 1/4 of 1% of
the liquidation preference ($25,000 per share) of the Preferred Shares held by
that Broker-Dealer's customer upon settlement in an auction.

     The Fund may request that the auction agent terminate one or more
Broker-Dealer agreements at any time upon five days' notice, provided that at
least one Broker-Dealer agreement is in effect after termination of the
agreement.

AUCTION PROCEDURES

     Prior to the submission deadline on each auction date for the Preferred
Shares, each customer of a Broker-Dealer who is listed on the records of that
Broker-Dealer (or, if applicable, the auction agent) as a beneficial owner of
Preferred Shares may submit the following types of orders with respect to shares
of such series of Preferred Shares to that Broker-Dealer:

          1. Hold Order -- indicating its desire to hold Preferred Shares
     without regard to the applicable rate for the next rate period.

          2. Bid -- indicating its desire to sell shares of such series at
     $25,000 per share if the applicable rate for shares of such series for the
     next period is less than the rate or spread specified in the bid.

          3. Sell Order -- indicating its desire to sell shares of such series
     at $25,000 per share without regard to the applicable rate for shares of
     such series for the next period.

     A beneficial owner of Preferred Shares may submit different types of orders
to its Broker-Dealer with respect to Preferred Shares then held by the
beneficial owner. A beneficial owner that submits a bid to its Broker-Dealer
having a rate higher than the maximum applicable rate on the auction date will
be treated as having submitted a sell order to its Broker-Dealer. A beneficial
owner that fails to submit an order to its Broker-Dealer will ordinarily be
deemed to have submitted a hold order to its Broker-Dealer. However, if a
beneficial owner fails to submit an order for some or all of its shares to its
Broker-Dealer for an auction relating to a rate period of more than 91 days,
such beneficial owner will be deemed to have submitted a sell order for such
shares to its Broker-Dealer. A sell order constitutes an irrevocable offer to
sell the

                                        37


Preferred Shares subject to the sell order. A beneficial owner that offers to
become the beneficial owner of additional Preferred Shares is, for the purposes
of such offer, a potential holder as discussed below.

     A potential holder is either a customer of a Broker-Dealer that is not a
beneficial owner of Preferred Shares but that wishes to purchase shares of such
series or that is a beneficial owner of shares of such series that wishes to
purchase additional shares of such series. A potential holder may submit bids to
its Broker-Dealer in which it offers to purchase shares of such series at
$25,000 per share if the applicable rate for the next dividend period is not
less than the specified rate in such bid. A bid placed by a potential holder
specifying a rate higher than the maximum rate for shares of such series on the
auction date will not be accepted.

     The Broker-Dealers in turn will submit the orders of their respective
customers who are beneficial owners and potential holders to the auction agent.
They will designate themselves (unless otherwise permitted by the Fund) as
existing holders of shares subject to orders submitted or deemed submitted to
them by beneficial owners. They will designate themselves as potential holders
of shares subject to orders submitted to them by potential holders. However,
neither the Fund nor the auction agent will be responsible for a Broker-Dealer's
failure to comply with these procedures. 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 the same way as an order placed with a Broker-Dealer by a
beneficial owner or potential holder. Similarly, any failure by a Broker-Dealer
to submit to the auction agent an order for any Preferred Shares held by it or
customers who are beneficial owners will be treated as a beneficial owner's
failure to submit to its Broker-Dealer an order in respect of Preferred Shares
held by it. A Broker-Dealer may also submit orders to the auction agent for its
own account as an existing holder or potential holder, provided it is not an
affiliate of the Fund.

     There are sufficient clearing bids in an auction if the number of shares
subject to bids submitted or deemed submitted to the auction agent by
Broker-Dealers for potential holders with rates or spreads equal to or lower
than the maximum applicable rate is at least equal to the number of shares of
such series subject to sell orders and the number of shares of such series
subject to bids specifying rates or spreads higher than the maximum applicable
rate for such series submitted or deemed submitted to the auction agent by
Broker-Dealers for existing holders of such series. If there are sufficient
clearing bids, the applicable rate for shares of such series for the next
succeeding rate period thereof will be the lowest rate specified in the
submitted bids which, taking into account such rate and all lower rates bid by
Broker-Dealers as or on behalf of existing holders and potential holders, would
result in existing holders and potential holders owning the shares of such
series available for purchase in the auction.

     If there are not sufficient clearing bids for such series, the applicable
rate for the next rate period will be the maximum rate on the auction date.
However, if the Fund has declared a special rate period and there are not
sufficient clearing bids, the election of a special rate period will not be
effective and the applicable rate for the next rate period will be the same as
during the current rate period. If there are not sufficient clearing bids,
beneficial owners of Preferred Shares that have submitted or are deemed to have
submitted sell orders may not be able to sell in the auction all shares subject
to such sell orders. If all of the outstanding Preferred Shares are the subject
of submitted hold orders, then the rate period following the auction will
automatically be the same length as the preceding rate period and the applicable
rate for the next rate period will be the seven-day AA Composite Commercial
Paper Rate in the case of a standard dividend period for the Series      ,
     ,      and      Preferred Shares and the 30-day AA Composite Commercial
Paper Rate for the Series      Preferred Shares.

     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 Preferred Shares that is different
than the number of shares specified in its order. To the extent the allocation
procedures have that result, Broker-Dealers that have 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.

                                        38


     Settlement of purchases and sales will be made on the next business day
(which is also a dividend payment date) after the auction date through DTC.
Purchasers will make payment through their agent members in same-day funds to
DTC against delivery to their respective Agent Members. DTC will make payment to
the sellers' Agent Members in accordance with DTC's normal procedures, which now
provide for payment against delivery by their Agent Members in same-day funds.

     The auctions for Series      ,      ,      and      Preferred Shares will
normally be held every seven days and the auction for Series      Preferred
Shares will normally be held every 28 days. Each subsequent rate period will
normally begin on the following business day.

     If an Auction Date is not a business day because the New York Stock
Exchange is closed for business for more than three consecutive business days
due to an act of God, natural disaster, act of war, civil or military
disturbance, act of terrorism, sabotage, riots or a loss or malfunction of
utilities or communications services, or the auction agent is not able to
conduct an auction in accordance with the Auction Procedures for any reason,
then the Auction Rate for the next dividend period will be the Auction Rate
determined on the previous Auction Date.

     If a Dividend Payment Date is not a business day because the New York Stock
Exchange is closed for business for more than three consecutive business days
due to an act of God, natural disaster, act of war, civil or military
disturbance, act of terrorism, sabotage, riots or a loss or malfunction of
utilities or communications services, or the dividend payable on such date can
not be paid for any such reason, then:

     - the Dividend Payment Date for the affected dividend period will be the
       next business day on which the trust and its paying agent, if any, can
       pay the dividend;

     - the affected dividend period will end on the day it otherwise would have
       ended; and

     - the next dividend period will begin and end on the dates on which it
       otherwise would have begun and ended.

     The following is a simplified example of how a typical auction works.
Assume that the Fund has 1,000 outstanding Preferred Shares of any series, and
three current holders. The three current holders and three potential holders
submit orders through Broker-Dealers at the auction:


                                                    
Current Holder A........  Owns 500 shares, wants to sell  Bid order of 4.1% rate for all
                          all 500 shares if auction rate  500 Shares
                          is less than 4.1%
Current Holder B........  Owns 300 shares, wants to hold  Hold order -- will take the
                                                          auction rate
Current Holder C........  Owns 200 shares, wants to sell  Bid order of 3.9% rate for all
                          all 200 shares if auction rate  200 shares
                          is less than 3.9%
Potential Holder D......  Wants to buy 200 shares         Places order to buy at or
                                                          above 4.0%
Potential Holder E......  Wants to buy 300 shares         Places order to buy at or
                                                          above 3.9%
Potential Holder F......  Wants to buy 200 shares         Places order to buy at or
                                                          above 4.1%


     The lowest dividend rate that will result in all 1,000 Preferred Shares
continuing to be held is 4.0% (the offer by D). Therefore, the dividend rate
will be 4.0%. Current holders B and C will continue to own their shares. Current
holder A will sell its shares because A's dividend rate bid was higher than the
dividend rate. Potential holder D will buy 200 shares and potential holder E
will buy 300 shares because their bid rates were at or below the dividend rate.
Potential holder F will not buy any shares because its bid rate was above the
dividend rate.

                                        39


SECONDARY MARKET TRADING AND TRANSFER OF PREFERRED SHARES

     The underwriters are not required to make a market in the Preferred Shares.
The Broker-Dealers (including the underwriters) may maintain a secondary trading
market for outside of auctions, but they are not required to do so. There can be
no assurance that a secondary trading market for Preferred Shares will develop
or, if it does develop, that it will provide owners with liquidity of
investment. Preferred Shares will not be registered on any stock exchange or on
the NASDAQ market.

     Investors who purchase Preferred Shares 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 dividend 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.

     A beneficial owner or an existing holder may sell, transfer or otherwise
dispose of Preferred Shares only in whole shares and only:

     - pursuant to a bid or sell order placed with the auction agent in
       accordance with the auction procedures;

     - to a Broker-Dealer; or

     - to such other persons as may be permitted by the Fund; provided, however,
       that (x) if you hold your Preferred Shares in the name of a
       Broker-Dealer, a sale or transfer of your Preferred Shares to that
       Broker-Dealer, or to another customer of that Broker-Dealer, will not be
       considered a sale or transfer for purposes of the foregoing if that
       Broker-Dealer remains the existing holder of the Preferred Shares
       immediately after the transaction; and (y) in the case of all transfers,
       other than through an auction, the Broker-Dealer (or other person, if the
       Fund permits) receiving the transfer will advise the auction agent of the
       transfer.

     Further description of the auction procedures can be found in the
Statement.

                           DESCRIPTION OF BORROWINGS

     [The Agreement and Declaration of Trust authorizes the Fund, without prior
approval of holders of common and preferred shares, including Preferred Shares,
to borrow money.] In this connection, the Fund may issue notes or other evidence
of indebtedness (including bank borrowings or commercial paper) and may secure
any such borrowings by mortgaging, pledging or otherwise subjecting as security
the Fund's assets. In connection with such borrowing, the Fund may be required
to maintain minimum average balances with the lender or to pay a commitment or
other fee to maintain a line of credit. Any such requirements will increase the
cost of borrowing over the stated interest rate.

     Limitations.  Under the requirements of the 1940 Act, the Fund, immediately
after issuing any Borrowings that are senior securities representing
indebtedness (as defined in the 1940 Act), must have an asset coverage of at
least 300%. With respect to any such Borrowings, asset coverage means the ratio
which the value of the total assets of the Fund, less all liabilities and
indebtedness not represented by senior securities, bears to the aggregate amount
of any such Borrowings that are senior securities representing indebtedness,
issued by the Fund. Certain types of Borrowings may also result in the Fund
being subject to covenants in credit agreements relating to asset coverages or
portfolio composition or otherwise. In addition, the Fund may be subject to
certain restrictions imposed by guidelines of one or more rating agencies which
may issue ratings for commercial paper or notes issued by the Fund. Such
restrictions may be more stringent than those imposed by the 1940 Act.

     Distribution Preference.  The rights of lenders to the Fund to receive
interest on and repayment of principal of any such Borrowings will be senior to
those of the Preferred Shares shareholders, and the terms of any such Borrowings
may contain provisions which limit certain activities of the Fund, including the
payment of dividends to Preferred Shares shareholders in certain circumstances.

                                        40


     Voting Rights.  The 1940 Act does (in certain circumstances) grant to the
lenders to the Fund certain voting rights in the event of default in the payment
of interest on or repayment of principal. In the event that such provisions
would impair the Fund's status as a regulated investment company under the Code,
the Fund, subject to its ability to liquidate its relatively illiquid portfolio,
intends to repay the Borrowings. Any Borrowing will likely be ranked senior or
equal to all other existing and future borrowings of the Fund, including
Preferred Shares.

     The discussion above describes the Board of Trustees' present intention
with respect to a possible offering of Borrowings. If the Board of Trustees
determines to authorize any of the foregoing, the terms may be the same as, or
different from, the terms described above, subject to applicable law and the
Fund's Declaration of Trust.

                          DESCRIPTION OF COMMON SHARES

     The Fund is authorized to issue an unlimited number of common shares,
without par value. The Board of Trustees is authorized, however, to classify and
reclassify any unissued shares into one or more additional classes or series of
shares. The Board of Trustees may establish such series or class, including
preferred shares, from time to time by setting or changing in any one or more
respects the designations, preferences, conversion or other rights, voting
powers, restrictions, limitations as to dividends, qualifications or terms or
conditions of redemption of such shares and pursuant to such classification or
reclassification to increase or decrease the number of authorized shares of any
existing class or series. The Board of Trustees, without shareholder approval,
is authorized to amend the Agreement and Declaration of Trust and By-laws to
reflect the terms of any such class or series.

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

     So long as any Preferred Shares of the Fund are outstanding, holders of
common shares will not be entitled to receive any net income of or other
distributions from the Fund unless all accumulated dividends on Preferred Shares
have been paid, and unless asset coverage (as defined in the 1940 Act) with
respect to Preferred Shares would be at least 200% after giving effect to such
distributions.

     The Common shares as listed on the New York Stock Exchange.

                                  TAX MATTERS

     The following is a description of certain U.S. federal income tax
consequences to a shareholder that acquires, holds and/or disposes of Preferred
Shares of the Fund. The discussion reflects applicable tax laws of the United
States as of the date of this prospectus, which tax laws may be changed or
subject to new interpretations by the courts or the Internal Revenue Service
("IRS") retroactively or prospectively. No attempt is made to present a detailed
explanation of U.S. federal income tax concerns affecting the Fund and its
shareholders, and the discussion set forth herein does not constitute tax
advice. In addition, no attempt is made to present state, local or foreign tax
concerns or tax concerns applicable to an investor with a special tax status
such as a financial institutional or non-U.S. investors. INVESTORS ARE URGED TO
CONSULT THEIR OWN TAX ADVISORS TO DETERMINE THE TAX CONSEQUENCES TO THEM OF
INVESTING IN THE FUND.

     The Fund intends to elect to be treated, and to qualify each year, as a
"regulated investment company" under Subchapter M of the Code so that it will
not pay U.S. federal income tax on income and capital gains distributed to
shareholders. If the Fund qualifies as a regulated investment company and
distributes to its shareholders at least 90% of the sum of (i) its "investment
company taxable income" as that term is defined in the Code (which includes,
among other things, dividends, taxable interest, the excess of any net
short-term capital gains over net long-term capital losses and certain net
foreign exchange gains as reduced by certain deductible expenses) without regard
to the deduction for dividends

                                        41


paid and (ii) the excess of its gross tax-exempt interest, if any, over certain
disallowed deductions, the Fund will be relieved of U.S. federal income tax on
any income of the Fund, including long-term capital gains, distributed to
shareholders. However, if the Fund retains any investment company income or "net
capital gain" (the excess of net long-term capital gain over net short-term
capital loss), it will be subject to U.S. federal income tax at regular
corporate rates (currently at the maximum rate of 35%) on the amount retained.
The Fund intends to distribute at least annually all or substantially all of its
investment company income, net tax-exempt interest, and net capital gain.

     If for any taxable year the Fund did not qualify as a regulated investment
company for U.S. federal income tax purposes, it would be treated as a U.S.
corporation subject to U.S. federal income tax and distributions to its
shareholders would not be deducted by the Fund in computing its taxable income.
In addition, in the event of a failure to qualify as a regulated investment
company, the Fund's distributions, to the extent derived from the Fund's current
or accumulated earnings and profits, would generally constitute ordinary
dividends, which although generally eligible for the corporate dividend received
deduction, would be taxable to shareholders as ordinary income, even though such
distributions might otherwise, at least in part, have been treated as long-term
capital gains in such shareholder's hands.

     Under present law, it is anticipated that Preferred Shares will constitute
stock of the Fund, and thus distributions with respect to Preferred Shares
(other than as described below and other than distributions in redemption of
Preferred Shares subject to Section 302(b) of the Code) will generally
constitute dividends to the extent of the Fund's current or accumulated earnings
and profits, as calculated for federal income tax purposes. Such dividends
generally will be taxable as ordinary income to holders and a portion of such
dividends may qualify for the dividends received deduction available to
corporations under Section 243 of the Code. Dividends designated by the Fund as
capital gain distributions will be treated as long-term capital gains in the
hands of holders regardless of the length of time such holders have held their
shares. Distributions in excess of current and accumulated earnings and profits
of the Fund are treated first as return of capital to the extent of the
shareholder's basis in the Preferred Shares and, thereafter, as capital gain.
The IRS currently requires that a regulated investment company that has two or
more classes of stock allocate to each such class proportionate amounts of each
type of its income (such as ordinary income and capital gains). Accordingly, the
Fund intends to designate distributions made with respect to Preferred Shares as
capital gain distributions in proportion to the Preferred Shares' share of total
dividends paid during the year. See "U.S. Federal Income Tax Matters" in the
Statement of Additional Information.

     If the Fund retains any net capital gain, the Fund may designate the
retained amount as undistributed capital gains in a notice to shareholders who,
if subject to U.S. federal income tax on long-term capital gains, (i) will be
required to include in income as long-term capital gain, their proportionate
share of such undistributed amount, and (ii) will be entitled to credit their
proportionate share of the tax paid by the Fund on the undistributed amount
against their U.S. federal income tax liabilities, if any, and to claim refunds
to the extent the credit exceeds such liabilities. If such an event occurs, the
tax basis of shares owned by a shareholder of the Fund will for U.S. federal
income tax purposes, generally be increased by the difference between the amount
of undistributed net capital gain included in the shareholder's gross income and
the tax deemed to have been paid by the shareholders.

     Sales and other dispositions of the Preferred Shares are taxable events for
shareholders that are subject to federal income tax. Shareholders should consult
their own tax advisors with reference to their individual circumstances to
determine whether any particular transaction in the Preferred Shares is properly
treated as a sale for tax purposes, as the following discussion assumes, and the
tax treatment of any gains or losses recognized in such transactions. Any loss
realized by a shareholder upon the sale or other disposition of shares with a
tax holding period of six months or less will be treated as a long-term capital
loss to the extent of any amounts treated as distributions of long-term capital
gain with respect to such shares. Losses on sales or other dispositions of
shares may be disallowed under the "wash sale" rules in the event of other
investments in the Fund (including those made pursuant to reinvestment of
dividends) within a period of 61 days beginning 30 days before and ending 30
days after a sale or other

                                        42


disposition of shares. In such a case, the disallowed portion of any loss
generally would be included in the U.S. federal tax basis of the shares acquired
in the other investments.

     The Fund is required in certain circumstances to backup withhold at a rate
of 30% (for calendar years 2002 and 2003) on reportable payments including
dividends, capital gain distributions, and proceeds of sales or other
dispositions of the Preferred Shares paid to certain holders of the Preferred
Shares who do not furnish the Fund with their correct social security number or
other taxpayer identification number and certain other certifications, or who
are otherwise subject to backup withholding. Backup withholding is not an
additional tax. Any amounts withheld from payments made to a shareholder may be
refunded or credited against such shareholder's U.S. federal income tax
liability, if any, provided that the required information is furnished to the
IRS.

     THE FOREGOING IS A GENERAL AND ABBREVIATED SUMMARY OF THE PROVISIONS OF THE
CODE AND THE TREASURY REGULATIONS IN EFFECT AS THEY DIRECTLY GOVERN THE TAXATION
OF THE FUND AND ITS SHAREHOLDERS. THESE PROVISIONS ARE SUBJECT TO CHANGE BY
LEGISLATIVE OR ADMINISTRATIVE ACTION, AND ANY SUCH CHANGE MAY BE RETROACTIVE. A
MORE COMPLETE DISCUSSION OF THE TAX RULES APPLICABLE TO THE FUND CAN BE FOUND IN
THE STATEMENT OF ADDITIONAL INFORMATION WHICH IS INCORPORATED BY REFERENCE INTO
THIS PROSPECTUS. SHAREHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING
SPECIFIC QUESTIONS AS TO U.S. FEDERAL, FOREIGN, STATE, AND LOCAL INCOME OR OTHER
TAXES.

                                        43


                    CERTAIN PROVISIONS OF THE AGREEMENT AND
                        DECLARATION OF TRUST AND BY-LAWS

     The Fund's Agreement and Declaration of Trust includes provisions that
could have the effect of limiting the ability of other entities or persons to
acquire control of the Fund or to change the composition of its Board of
Trustees and could have the effect of depriving shareholders of an opportunity
to sell their shares at a premium over prevailing market prices by discouraging
a third party from seeking to obtain control of the Fund. The Board of Trustees
is divided into three classes of approximately equal size. The terms of the
Trustees of the different classes are staggered so that approximately one third
of the Board of Trustees is elected by shareholders each year. A Trustee may be
removed from office with or without cause by a vote of at least a majority of
the then Trustees if such removal is approved by the holders of at least 75% of
the shares entitled to be voted with respect to the election of such Trustee and
present in person or by proxy at a meeting of shareholders called for such
purpose.

     In addition, the Agreement and Declaration of Trust requires the
affirmative vote of at least 75% of the outstanding shares entitled to vote on
the matter for the Trust to merge or consolidate with any other corporation,
association, trust or other organization or to sell, lease or exchange all or
substantially all of the Fund's assets; unless such action has been approved,
adopted or authorized by the affirmative vote of at least 75% of the Trustees
then in office, in which case, the affirmative vote of a majority of the shares
entitled to vote on the matter is required.

     In addition, conversion of the Fund to an open-end investment company would
require an amendment to the Fund's Agreement and Declaration of Trust. Such an
amendment would require the favorable vote of a majority of the then Trustees
followed by a favorable vote of the holders of at least 75% of the shares
entitled to vote on the matter, voting as separate classes or series (or a
majority of such shares if the amendment was previously approved by 75% of the
Trustees). Such a vote also would satisfy a separate requirement in the 1940 Act
that the change be approved by the shareholders. Shareholders of an open-end
investment company may require the company to redeem their shares of common
stock at any time (except in certain circumstances as authorized by or under the
1940 Act) at their net asset value, less such redemption charge, if any, as
might be in effect at the time of a redemption. If the Fund is converted to an
open-end investment company, it could be required to liquidate portfolio
securities to meet requests for redemption, and the common shares would no
longer be listed on the New York Stock Exchange. Conversion to an open-end
investment company would also require changes in certain of the Fund's
investment policies and restrictions, such as those relating to the purchase of
illiquid securities.

     In addition, the Agreement and Declaration of Trust requires the
affirmative vote of consent of a majority of the then Trustees followed by the
affirmative vote or consent of the holders of at least 75% of the shares of each
affected class or series of the Fund, voting separately as a class or series, to
approve, adopt or authorize certain transactions with 5% or greater holders of a
class or series of shares and their associates, unless the transaction has been
approved by at least 75% of the Trustees, in which case "a majority of the
outstanding voting securities" (as defined in the 1940 Act) entitled to vote
shall be required. For purposes of these provisions, a 5% or greater holder of a
class or series of shares (a "Principal Shareholder") refers to any person who,
whether directly or indirectly and whether alone or together with its affiliates
and associates, beneficially owns 5% or more of the outstanding shares of any
class or series of shares of beneficial interest of the Fund. The 5% holder
transactions subject to these special approval requirements are:

     - the merger or consolidation of the Fund or any subsidiary of the Fund
       with or into any Principal Shareholder;

     - the issuance of any securities of the Fund to any Principal Shareholder
       for cash; or

     - the sale, lease or exchange to the Fund or any subsidiary of the Fund, in
       exchange for securities of the Fund, of any assets of any Principal
       Shareholder, except assets having an aggregate fair market value of less
       than $1,000,000, aggregating for purposes of such computation all assets
       sold, leased or exchanged in any series of similar transactions within a
       12-month period.

                                        44


     The Fund may be terminated by the affirmative vote of not less than 75% of
the Trustees then in office by written notice to the shareholders.

     The Agreement and Declaration of Trust and By-laws provide that the Board
of Trustees has the power, to the exclusion of shareholders, to make, alter or
repeal any of the By-laws (except for any by-law specified not to be amended or
repealed by the Board), subject to the requirements of the 1940 Act. Neither
this provision of the Agreement and Declaration of Trust, nor any of the
foregoing provisions thereof requiring the affirmative vote of 75% of
outstanding shares of the Fund, can be amended or repealed except by the vote of
such required number of shares.

     The Fund's By-laws generally require that advance notice be given to the
Fund in the event a shareholder desires to nominate a person for election to the
Board of Trustees or to transact any other business at an annual meeting of
shareholders. With respect to an annual meeting following the first annual
meeting of shareholders, notice of any such nomination or business must be
delivered to or received at the principal executive offices of the Fund not less
than 90 calendar days nor more than 120 calendar days prior to the anniversary
date of the prior year's annual meeting (subject to certain exceptions). In the
case of the first annual meeting of shareholders, the notice must be given no
later than the tenth calendar day following public disclosure as specified in
the By-laws of the date of the meeting. Any notice by a shareholder must be
accompanied by certain information as provided in the By-laws.

                   CUSTODIAN, AUCTION AGENT, TRANSFER AGENT,
                      DIVIDEND PAYING AGENT AND REGISTRAR

     The Fund's securities and cash are held under a custodian agreement with
The Bank of New York, One Wall Street, New York, New York 10286. The transfer
agent, dividend disbursing agent and registrar for the Fund's shares is also The

Shares and acts as transfer agent, dividend paying agent and registrar with
respect to Preferred Shares.

     Subject to the terms and conditions of the purchase agreement dated
          , 2002, each Underwriter, named below has severally agreed to
purchase, and the Fund has agreed to sell to such Underwriter, the number of
Preferred Shares set forth opposite the name of such Underwriter.

     The purchase agreement provides that the obligations of the underwriters to
purchase the shares included in this offering are subject to the approval of
certain legal matters by counsel and to certain other conditions, including
without limitation, the receipt by the Underwriters of customary closing
certificates, opinions and other documents and the receipt by the Fund of
     and      ratings on the Preferred Shares by Moody's and Fitch,
respectively, as of the time of the offering. The Underwriters are obligated to
purchase all the Preferred Shares if they purchase any of the shares. In the
purchase agreement, the Fund and Calamos have agreed to indemnify the
Underwriters against certain liabilities under the Securities Act of 1933, as
amended, or to contribute payments the Underwriters may be required to make for
any of those liabilities.

     The Underwriters propose to initially offer some of the Preferred Shares
directly to the public at the public offering price set forth on the cover page
of this prospectus and some of the Preferred Shares to certain dealers at the
public offering price less a concession not in excess of $     per share. The
sales load the Fund will pay of $     per share is equal to   % of the initial
offering price of the Preferred Shares. After the initial public offering, the
Underwriters may change the public offering price and the concession. Investors
must pay for any shares purchased in the initial public offering on or before
          , 2002.

     The Fund anticipates that the Underwriters may from time to time act as
brokers or dealers in executing the Fund's portfolio transactions after they
have ceased to be underwriters.

     The Fund anticipates that the Underwriters or their respective affiliates
may, from time to time, act in auctions as broker-dealers and receive fees as
set forth under "The Auction" and in the statement of additional information.
The Underwriters are active underwriters of, and dealers in, securities and act
as market makers in a number of such securities, and therefore can be expected
to engage in portfolio transactions with, and perform services for, the Fund.

     The principal business address of           is           .

     The settlement date for the purchase of the Preferred Shares will be
          , 2002, as agreed upon by the Underwriters, the Fund and Calamos
pursuant to Rule 15c6-1 under the Securities Exchange Act of 1934.

                                 LEGAL OPINIONS

     Bell, Boyd & Lloyd LLC, Chicago, Illinois, serves as counsel to the Fund
and to the non-interested Trustees. Vedder, Price, Kaufman & Kammholz ("Vedder
Price"), Chicago, Illinois, which is serving as special counsel to the Fund in
connection with the offering, will pass on the legality of the shares offered
hereby. Vedder Price is also counsel to Calamos. Certain matters will be passed

                                 USE OF PROCEEDS

         The Fund will invest the net proceeds of the offering in accordance
with the Fund's investment objective and policies as stated below. It is
presently anticipated that the Fund will be able to invest substantially all of
the net proceeds in securities that meet the investment objective and policies
within three months after completion of the offering. Pending such investment,
the net proceeds may be invested in U.S. government securities high grade,
short-term money market instruments. If necessary, the Fund may also purchase,
as temporary investments, securities of other open- or closed-end investment
companies that invest primarily the types of securities in which the Fund may
invest directly.

                        INVESTMENT OBJECTIVE AND POLICIES

         The prospectus presents the investment objective and the principal
investment strategies and risks of the Fund. This section supplements the
disclosure in the Fund's prospectus and provides additional information on the
Fund's investment policies or restrictions. Restrictions or policies stated as a
maximum percentage of the Fund's assets are only applied immediately after a
portfolio investment to which the policy or restriction is applicable (other
than the limitations on borrowing). Accordingly, any later increase or decrease
resulting from a change in values, net assets or other circumstances will not be
considered in determining whether the investment complies with the Fund's
restrictions and policies.

PRIMARY INVESTMENTS

         Under normal circumstances, the Fund will invest at least 80% of its
managed assets in a diversified portfolio of convertible securities and
non-convertible income securities. The Fund will provide written notice to
shareholders at least 60 days prior to any change to the requirement that it
invest at least 80% of its managed assets as described in the sentence above.
The portion of the Fund's assets invested in convertible securities and
non-convertible income securities will vary from time to time in light of the
Fund's investment objective, changes in equity prices and changes in interest
rates and other economic and market factors, although, under normal
circumstances, the Fund will invest at least 50% of its managed assets in
convertible securities. "Managed assets" means the total assets of the Fund
(including any assets attributable to any leverage that may be outstanding)
minus the sum of accrued liabilities (other than debt representing financial
leverage). For this purpose, the liquidation preference on the preferred shares
will not constitute a liability.

CONVERTIBLE SECURITIES

         Convertible securities include any corporate debt security or preferred
stock that may be converted into underlying shares of common stock. The common
stock underlying convertible securities may be issued by a different entity than
the issuer of the convertible securities. Convertible securities entitle the
holder to receive interest payments paid on corporate debt securities or the
dividend preference on a preferred stock until such time as the convertible
security matures or is redeemed or until the holder elects to exercise the
conversion privilege. As a result of the conversion feature, however, the
interest rate or dividend preference on a convertible security is generally less
than would be the case if the securities were issued in non-convertible form.

         The value of convertible securities is influenced by both the yield of
non-convertible securities of comparable issuers and by the value of the
underlying common stock. The value of a convertible security viewed without
regard to its conversion feature (i.e., strictly on the basis of its yield) is
sometimes referred to as its "investment value." The investment value of the


                                      S-2


convertible security typically will fluctuate inversely with changes in
prevailing interest rates. However, at the same time, the convertible security
will be influenced by its "conversion value," which is the market value of the
underlying common stock that would be obtained if the convertible security were
converted. Conversion value fluctuates directly with the price of the underlying
common stock.

         If, because of a low price of the common stock, the conversion value is
substantially below the investment value of the convertible security, the price
of the convertible security is governed principally by its investment value. If
the conversion value of a convertible security increases to a point that
approximates or exceeds its investment value, the value of the security will be
principally influenced by its conversion value. A convertible security will sell
at a premium over its conversion value to the extent investors place value on
the right to acquire the underlying common stock while holding a fixed income
security. Holders of convertible securities have a claim on the assets of the
issuer prior to the common stockholders, but may be subordinated to holders of
similar non-convertible securities of the same issuer.

SYNTHETIC CONVERTIBLE SECURITIES

         Calamos Asset Management, Inc. ("Calamos") may create a "synthetic"
convertible security by combining fixed income securities with the right to
acquire equity securities. More flexibility is possible in the assembly of a
synthetic convertible security than in the purchase of a convertible security.
Although synthetic convertible securities may be selected where the two
components are issued by a single issuer, thus making the synthetic convertible
security similar to the true convertible security, the character of a synthetic
convertible security allows the combination of components representing distinct
issuers, when Calamos believes that such a combination would better promote the
Fund's investment objective. A synthetic convertible security also is a more
flexible investment in that its two components may be purchased separately. For
example, the Fund may purchase a warrant for inclusion in a synthetic
convertible security but temporarily hold short-term investments while
postponing the purchase of a corresponding bond pending development of more
favorable market conditions.

         A holder of a synthetic convertible security faces the risk of a
decline in the price of the security or the level of the index involved in the
convertible component, causing a decline in the value of the call option or
warrant purchased to create the synthetic convertible security. Should the price
of the stock fall below the exercise price and remain there throughout the
exercise period, the entire amount paid for the call option or warrant would be
lost. Because a synthetic convertible security includes the fixed-income
component as well, the holder of a synthetic convertible security also faces the
risk that interest rates will rise, causing a decline in the value of the
fixed-income instrument.

         The Fund may also purchase synthetic convertible securities
manufactured by other parties, including convertible structured notes.
Convertible structured notes are fixed income debentures linked to equity, and
are typically issued by investment banks. Convertible structured notes have the
attributes of a convertible security, however, the investment bank that issued
the convertible note assumes the credit risk associated with the investment,
rather than the issuer of the underlying common stock into which the note is
convertible.

         The Fund's holdings of synthetic convertible securities are considered
convertible securities for purposes of the Fund's policy to invest at least 50%
of its assets in convertible securities and 80% of its managed assets in a
diversified portfolio of convertible and non-convertible income securities.

HIGH YIELD SECURITIES

         A substantial portion of the Fund's assets may be invested in below
investment grade (high yield, high risk) securities. The high yield securities
in which the Fund invests are rated Ba or lower by Moody's or BB or lower by
Standard & Poor's or are unrated but determined by Calamos to be of

                                      S-3


comparable quality. Debt securities rated below investment grade are commonly
referred to as "junk bonds" and are considered speculative with respect to the
issuer's capacity to pay interest and repay principal.

         INVESTMENT IN HIGH YIELD SECURITIES INVOLVES SUBSTANTIAL RISK OF LOSS.
Below investment grade debt securities or comparable unrated securities are
commonly referred to as "junk bonds" and are considered predominantly
speculative with respect to the issuer's ability to pay interest and principal
and are susceptible to default or decline in market value due to adverse
economic and business developments. The market values for high yield securities
tend to be very volatile, and these securities are less liquid than investment
grade debt securities. For these reasons, your investment in the Fund is subject
to the following specific risks:

         -    increased price sensitivity to changing interest rates and to a
              deteriorating economic environment;

         -    greater risk of loss due to default or declining credit quality;

         -    adverse company specific events are more likely to render the
              issuer unable to make interest and/or principal payments; and

         -    if a negative perception of the high yield market develops, the
              price and liquidity of high yield securities may be depressed.
              This negative perception could last for a significant period of
              time.

         Debt securities rated below investment grade are speculative with
respect to the capacity to pay interest and repay principal in accordance with
the terms of such securities. A rating of C from Moody's means that the issue so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing. Standard & Poor's assigns a rating of C to issues that
are currently highly vulnerable to nonpayment, and the C rating may be used to
cover a situation where a bankruptcy petition has been filed or similar action
taken, but payments on the obligation are being continued (a C rating is also
assigned to a preferred stock issue in arrears on dividends or sinking fund
payments, but that is currently paying). See Appendix A to this statement of
additional information for a description of Moody's and Standard & Poor's
ratings.

         Adverse changes in economic conditions are more likely to lead to a
weakened capacity of a high yield issuer to make principal payments and interest
payments than an investment grade issuer. The principal amount of high yield
securities outstanding has proliferated in the past decade as an increasing
number of issuers have used high yield securities for corporate financing. An
economic downturn could severely affect the ability of highly leveraged issuers
to service their debt obligations or to repay their obligations upon maturity.
Similarly, down-turns in profitability in specific industries could adversely
affect the ability of high yield issuers in that industry to meet their
obligations. The market values of lower quality debt securities tend to reflect
individual developments of the issuer to a greater extent than do higher quality
securities, which react primarily to fluctuations in the general level of
interest rates. Factors having an adverse impact on the market value of lower
quality securities may have an adverse effect on the Fund's net asset value and
the market value of its common shares. In addition, the Fund may incur
additional expenses to the extent it is required to seek recovery upon a default
in payment of principal or interest on its portfolio holdings. In certain
circumstances, the Fund may be required to foreclose on an issuer's assets and
take possession of its property or operations. In such circumstances, the Fund
would incur additional costs in disposing of such assets and potential
liabilities from operating any business acquired.

                                      S-4


         The secondary market for high yield securities may not be as liquid as
the secondary market for more highly rated securities, a factor which may have
an adverse effect on the Fund's ability to dispose of a particular security when
necessary to meet its liquidity needs. There are fewer dealers in the market for
high yield securities than investment grade obligations. The prices quoted by
different dealers may vary significantly and the spread between the bid and
asked price is generally much larger than higher quality instruments. Under
adverse market or economic conditions, the secondary market for high yield
securities could contract further, independent of any specific adverse changes
in the condition of a particular issuer, and these instruments may become
illiquid. As a result, the Fund could find it more difficult to sell these
securities or may be able to sell the securities only at prices lower than if
such securities were widely traded. Prices realized upon the sale of such lower
rated or unrated securities, under these circumstances, may be less than the
prices used in calculating the Fund's net asset value.

         Since investors generally perceive that there are greater risks
associated with lower quality debt securities of the type in which the Fund may
invest a portion of its assets, the yields and prices of such securities may
tend to fluctuate more than those for higher rated securities. In the lower
quality segments of the debt securities market, changes in perceptions of
issuers' creditworthiness tend to occur more frequently and in a more pronounced
manner than do changes in higher quality segments of the debt securities market,
resulting in greater yield and price volatility.

         If the Fund invests in high yield securities that are rated C or below,
the Fund will incur significant risk in addition to the risks associated with
investments in high yield securities and corporate loans. Distressed securities
frequently do not produce income while they are outstanding. The Fund may
purchase distressed securities that are in default or the issuers of which are
in bankruptcy. The Fund may be required to bear certain extraordinary expenses
in order to protect and recover its investment.

DISTRESSED SECURITIES

         The Fund may, but currently does not intend to, invest up to 5% of its
total assets in distressed securities, including corporate loans, which are the
subject of bankruptcy proceedings or otherwise in default as to the repayment of
principal and/or payment of interest at the time of acquisition by the Fund or
are rated in the lower rating categories (Ca or lower by Moody's or CC or lower
by Standard & Poor's) or which are unrated investments considered by Calamos to
be of comparable quality. Investment in distressed securities is speculative and
involves significant risk. Distressed securities frequently do not produce
income while they are outstanding and may require the Fund to bear certain
extraordinary expenses in order to protect and recover its investment.
Therefore, to the extent the Fund seeks capital appreciation through investment
in distressed securities, the Fund's ability to achieve current income for its
shareholders may be diminished. The Fund also will be subject to significant
uncertainty as to when and in what manner and for what value the obligations
evidenced by the distressed securities will eventually be satisfied (e.g.,
through a liquidation of the obligor's assets, an exchange offer or plan of
reorganization involving the distressed securities or a payment of some amount
in satisfaction of the obligation). In addition, even if an exchange offer is
made or a plan of reorganization is adopted with respect to distressed
securities held by the Fund, there can be no assurance that the securities or
other assets received by the Fund in connection with such exchange offer or plan
of reorganization will not have a lower value or income potential than may have
been anticipated when the investment was made. Moreover, any securities received
by the Fund upon completion of an exchange offer or plan of reorganization may
be restricted as to resale. As a result of the Fund's participation in
negotiations with respect to any exchange offer or plan of reorganization with
respect to an issuer of distressed securities, the Fund may be restricted from
disposing of such securities.

                                      S-5


LOANS

         The Fund may invest up to 5% of its total assets in loan participations
and other direct claims against a borrower. The corporate loans in which the
Fund invests primarily consist of direct obligations of a borrower and may
include debtor in possession financings pursuant to Chapter 11 of the U.S.
Bankruptcy Code, obligations of a borrower issued in connection with a
restructuring pursuant to Chapter 11 of the U.S. Bankruptcy Code, leveraged
buy-out loans, leveraged recapitalization loans, receivables purchase
facilities, and privately placed notes. The Fund may invest in a corporate loan
at origination as a co-lender or by acquiring in the secondary market
participations in, assignments of or novations of a corporate loan. By
purchasing a participation, the Fund acquires some or all of the interest of a
bank or other lending institution in a loan to a corporate or government
borrower. The participations typically will result in the Fund having a
contractual relationship only with the lender not the borrower. The Fund will
have the right to receive payments of principal, interest and any fees to which
it is entitled only from the lender selling the participation and only upon
receipt by the lender of the payments from the borrower. Many such loans are
secured, although some may be unsecured. Such loans may be in default at the
time of purchase. Loans that are fully secured offer the Fund more protection
than an unsecured loan in the event of non-payment of scheduled interest or
principal. However, there is no assurance that the liquidation of collateral
from a secured loan would satisfy the corporate borrower's obligation, or that
the collateral can be liquidated. Direct debt instruments may involve a risk of
loss in case of default or insolvency of the borrower and may offer less legal
protection to the Fund in the event of fraud or misrepresentation. In addition,
loan participations involve a risk of insolvency of the lending bank or other
financial intermediary. The markets in loans are not regulated by federal
securities laws or the Securities and Exchange Commission (SEC).

         As in the case of other high yield investments, such corporate loans
may be rated in the lower rating categories of the established rating services
(Ba or lower by Moody's or BB or lower by Standard & Poor's), or may be unrated
investments considered by Calamos to be of comparable quality. As in the case of
other high yield investments, such corporate loans can be expected to provide
higher yields than lower yielding, higher rated fixed income securities, but may
be subject to greater risk of loss of principal and income. There are, however,
some significant differences between corporate loans and high yield bonds.
Corporate loan obligations are frequently secured by pledges of liens and
security interests in the assets of the borrower, and the holders of corporate
loans are frequently the beneficiaries of debt service subordination provisions
imposed on the borrower's bondholders. These arrangements are designed to give
corporate loan investors preferential treatment over high yield investors in the
event of a deterioration in the credit quality of the issuer. Even when these
arrangements exist, however, there can be no assurance that the borrowers of the
corporate loans will repay principal and/or pay interest in full. Corporate
loans generally bear interest at rates set at a margin above a generally
recognized base lending rate that may fluctuate on a day-to-day basis, in the
case of the prime rate of a U.S. bank, or which may be adjusted on set dates,
typically 30 days but generally not more than one year, in the case of the
London Interbank Offered Rate. Consequently, the value of corporate loans held
by the Fund may be expected to fluctuate significantly less than the value of
other fixed rate high yield instruments as a result of changes in the interest
rate environment. On the other hand, the secondary dealer market for certain
corporate loans may not be as well developed as the secondary dealer market for
high yield bonds, and therefore presents increased market risk relating to
liquidity and pricing concerns.

FOREIGN SECURITIES

         The Fund may invest up to 25% of its net assets, in securities of
foreign issuers. For this purpose, foreign securities do not include American
Depositary Receipts ("ADRs") or securities guaranteed by a United States person,
but may include foreign securities in the form of European Depositary Receipts
("EDRs"), Global Depositary Receipts ("GDRs") or other securities representing
underlying shares of

                                      S-6


foreign issuers. Positions in those securities are not necessarily denominated
in the same currency as the common stocks into which they may be converted. ADRs
are receipts typically issued by an American bank or trust company evidencing
ownership of the underlying securities. EDRs are European receipts listed on the
Luxembourg Stock Exchange evidencing a similar arrangement. GDRs are U.S.
dollar-denominated receipts evidencing ownership of foreign securities.
Generally, ADRs, in registered form, are designed for the U.S. securities
markets and EDRs and GDRs, in bearer form, are designed for use in foreign
securities markets. The Fund may invest in sponsored or unsponsored ADRs. In the
case of an unsponsored ADR, the Fund is likely to bear its proportionate share
of the expenses of the depository and it may have greater difficulty in
receiving shareholder communications than it would have with a sponsored ADR.

         To the extent positions in portfolio securities are denominated in
foreign currencies, the Fund's investment performance is affected by the
strength or weakness of the U.S. dollar against those currencies. For example,
if the dollar falls in value relative to the Japanese yen, the dollar value of a
Japanese stock held in the portfolio will rise even though the price of the
stock remains unchanged. Conversely, if the dollar rises in value relative to
the yen, the dollar value of the Japanese stock will fall. (See discussion of
transaction hedging and portfolio hedging below under "Currency Exchange
Transactions.")

         Investors should understand and consider carefully the risks involved
in foreign investing. Investing in foreign securities, which are generally
denominated in foreign currencies, and utilization of forward foreign currency
exchange contracts involve certain considerations comprising both risks and
opportunities not typically associated with investing in U.S. securities. These
considerations include: fluctuations in exchange rates of foreign currencies;
possible imposition of exchange control regulation or currency restrictions that
would prevent cash from being brought back to the United States less public
information with respect to issuers of securities; less governmental supervision
of stock exchanges, securities brokers, and issuers of securities; lack of
uniform accounting, auditing and financial reporting standards; lack of uniform
settlement periods and trading practices; less liquidity and frequently greater
price volatility in foreign markets than in the United States; possible
imposition of foreign taxes; and sometimes less advantageous legal, operational
and financial protections applicable to foreign sub-custodial arrangements.

         Although the Fund intends to invest in companies and government
securities of countries having stable political environments, there is the
possibility of expropriation or confiscatory taxation, seizure or
nationalization of foreign bank deposits or other assets, establishment of
exchange controls, the adoption of foreign government restrictions, or other
adverse political, social or diplomatic developments that could affect
investment in these nations.

         The Fund expects that substantially all of its investments will be in
developed nations. However, the Fund may invest in the securities of emerging
countries. The securities markets of emerging countries are substantially
smaller, less developed, less liquid and more volatile than the securities
markets of the U.S. and other more developed countries. Disclosure and
regulatory standards in many respects are less stringent than in the U.S. and
other major markets. There also may be a lower level of monitoring and
regulation of emerging markets and the activities of investors in such markets,
and enforcement of existing regulations has been extremely limited. Economies in
individual emerging markets may differ favorably or unfavorably from the U.S.
economy in such respects as growth of gross domestic product, rates of
inflation, currency depreciation, capital reinvestment, resource
self-sufficiency and balance of payments positions. Many emerging market
countries have experienced high rates of inflation for many years, which has had
and may continue to have very negative effects on the economies and securities
markets of those countries.

CURRENCY EXCHANGE TRANSACTIONS

         Currency exchange transactions may be conducted either on a spot (i.e.,
cash) basis at the spot rate for purchasing or selling currency prevailing in
the foreign exchange market or through forward currency exchange contracts
("forward contracts"). Forward contracts are contractual agreements to purchase
or sell a specified currency at a specified future date (or within a specified
time period) and price set at the time of the contract. Forward contracts are
usually entered into with banks, foreign exchange dealers and broker-dealers,
are not exchange traded, and are usually for less than one year, but may be
renewed.

         Forward currency exchange transactions may involve currencies of the
different countries in which the Fund may invest and serve as hedges against
possible variations in the exchange rate between these currencies. Currency
exchange transactions are limited to transaction hedging and portfolio hedging
involving either specific transactions or portfolio positions, except to the
extent described below under "Synthetic Foreign Money Market Positions."
Transaction hedging is the purchase or sale of forward contracts with respect to
specific receivables or payables of the Fund accruing in connection with the
purchase and sale of its portfolio securities or the receipt of dividends or
interest thereon. Portfolio hedging is the use of forward contracts with respect
to portfolio security positions denominated or quoted in a particular foreign
currency. Portfolio hedging allows the Fund to limit or reduce its exposure in a
foreign currency by entering into a forward contract to sell such foreign
currency (or another foreign currency that acts as a proxy for that currency) at
a future date for a price payable in U.S. dollars so that the value of the
foreign denominated portfolio securities can be approximately matched by a
foreign denominated liability. The Fund may not engage in portfolio hedging with
respect to the currency of a particular country to an extent greater than the
aggregate market value (at the time of making such sale) of the securities held
in its portfolio denominated or quoted in that particular currency, except that
the Fund may hedge all or part of its foreign currency exposure through the use
of a basket of currencies or a proxy currency where such currencies or currency
act as an effective proxy for other currencies. In such a case, the Fund may
enter into a forward contract where the amount of the foreign currency to be
sold exceeds the value of the securities denominated in such currency. The use
of this basket hedging technique may be more efficient and economical than
entering into separate forward contracts for each currency held in the Fund. The
Fund may not engage in "speculative" currency exchange transactions.

         If the Fund enters into a forward contract, the Fund's custodian will
segregate liquid assets of the Fund having a value equal to the Fund's
commitment under such forward contract. At the maturity of the forward contract
to deliver a particular currency, the Fund may either sell the portfolio
security related to the contract and make delivery of the currency, or it may
retain the security and either acquire the currency on the spot market or
terminate its contractual obligation to deliver the currency by purchasing an
offsetting contract with the same currency trader obligating it to purchase on
the same maturity date the same amount of the currency. It is impossible to
forecast with absolute precision the market value of portfolio securities at the
expiration of a forward contract. Accordingly, it may be necessary for a Fund to
purchase additional currency on the spot market (and bear the expense of such
purchase) if the market value of the security is less than the amount of
currency the Fund is obligated to deliver and if a decision is made to sell the
security and make delivery of the currency. Conversely, it may be necessary to
sell on the spot market some of the currency received upon the sale of the
portfolio security if its market value exceeds the amount of currency the Fund
is obligated to deliver.

         If the Fund retains the portfolio security and engages in an offsetting
transaction, the Fund will incur a gain or a loss to the extent that there has
been movement in forward contract prices. If the Fund engages in an offsetting
transaction, it may subsequently enter into a new forward contract to sell the
currency. Should forward prices decline during the period between the Fund's
entering into a forward contract for the sale of a currency and the date it
enters into an offsetting contract for the purchase of the


                                      S-8


currency, the Fund will realize a gain to the extent the price of the currency
it has agreed to sell exceeds the price of the currency it has agreed to
purchase. Should forward prices increase, the Fund will suffer a loss to the
extent the price of the currency it has agreed to purchase exceeds the price of
the currency it has agreed to sell. A default on the contract would deprive the
Fund of unrealized profits or force the Fund to cover its commitments for
purchase or sale of currency, if any, at the current market price.

         Hedging against a decline in the value of a currency does not eliminate
fluctuations in the value of a portfolio security traded in that currency or
prevent a loss if the value of the security declines. Hedging transactions also
preclude the opportunity for gain if the value of the hedged currency should
rise. Moreover, it may not be possible for a Fund to hedge against a devaluation
that is so generally anticipated that the Fund is not able to contract to sell
the currency at a price above the devaluation level it anticipates. The cost to
the Fund of engaging in currency exchange transactions varies with such factors
as the currency involved, the length of the contract period, and prevailing
market conditions. Because currency exchange transactions are usually conducted
on a principal basis, no fees or commissions are involved.

SYNTHETIC FOREIGN MONEY MARKET POSITIONS

         The Fund may invest in money market instruments denominated in foreign
currencies. In addition to, or in lieu of, such direct investment, the Fund may
construct a synthetic foreign money market position by (a) purchasing a money
market instrument denominated in one currency, generally U.S. dollars, and (b)
concurrently entering into a forward contract to deliver a corresponding amount
of that currency in exchange for a different currency on a future date and at a
specified rate of exchange. For example, a synthetic money market position in
Japanese yen could be constructed by purchasing a U.S. dollar money market
instrument, and entering concurrently into a forward contract to deliver a
corresponding amount of U.S. dollars in exchange for Japanese yen on a specified
date and at a specified rate of exchange. Because of the availability of a
variety of highly liquid short-term U.S. dollar money market instruments, a
synthetic money market position utilizing such U.S. dollar instruments may offer
greater liquidity than direct investment in foreign currency and a concurrent
construction of a synthetic position in such foreign currency, in terms of both
income yield and gain or loss from changes in currency exchange rates, in
general should be similar, but would not be identical because the components of
the alternative investments would not be identical.

DEBT OBLIGATIONS OF NON-U.S. GOVERNMENTS

         An investment in debt obligations of non-U.S. governments and their
political subdivisions (sovereign debt) involves special risks that are not
present in corporate debt obligations. The non-U.S. issuer of the sovereign debt
or the non-U.S. governmental authorities that control the repayment of the debt
may be unable or unwilling to repay principal or interest when due, and the Fund
may have limited recourse in the event of a default. During periods of economic
uncertainty, the market prices of sovereign debt may be more volatile than
prices of debt obligations of U.S. issuers. In the past, certain non-U.S.
countries have encountered difficulties in servicing their debt obligations,
withheld payments of principal and interest and declared moratoria on the
payment of principal and interest on their sovereign debt.

         A sovereign debtor's willingness or ability to repay principal and pay
interest in a timely manner may be affected by, among other factors, its cash
flow situation, the extent of its foreign currency reserves, the availability of
sufficient non-U.S. currency, the relative size of the debt service burden, the
sovereign debtor's policy toward its principal international lenders and local
political constraints. Sovereign debtors may also be dependent on expected
disbursements from non-U.S. governments, multilateral agencies and other
entities to reduce principal and interest arrearages on their debt. The failure
of a sovereign debtor to implement economic reforms, achieve specified levels of
economic performance or repay principal or interest when due may result in the
cancellation of third-party


                                      S-9


commitments to lend funds to the sovereign debtor, which may further impair such
debtor's ability or willingness to service its debts.

         EURODOLLAR INSTRUMENTS AND SAMURAI AND YANKEE BONDS. The Fund may
invest in Eurodollar instruments and Samurai and Yankee bonds. Eurodollar
instruments are bonds of corporate and government issuers that pay interest and
principal in U.S. dollars but are issued in markets outside the United States,
primarily in Europe. Samurai bonds are yen-denominated bonds sold in Japan by
non-Japanese issuers. Yankee bonds are U.S. dollar-denominated bonds typically
issued in the U.S. by non-U.S. governments and their agencies and non-U.S. banks
and corporations. The Fund may also invest in Eurodollar Certificates of Deposit
("ECDs"), Eurodollar Time Deposits ("ETDs") and Yankee Certificates of Deposit
("Yankee CDs"). ECDs are U.S. dollar-denominated certificates of deposit issued
by non-U.S. branches of domestic banks; ETDs are U.S. dollar-denominated
deposits in a non-U.S. branch of a U.S. bank or in a non-U.S. bank; and Yankee
CDs are U.S. dollar-denominated certificates of deposit issued by a U.S. branch
of a non-U.S. bank and held in the U.S. These investments involve risks that are
different from investments in securities issued by U.S. issuers, including
potential unfavorable political and economic developments, non-U.S. withholding
or other taxes, seizure of non-U.S. deposits, currency controls, interest
limitations or other governmental restrictions which might affect payment of
principal or interest.

LENDING OF PORTFOLIO SECURITIES

         The Fund may lend its portfolio securities to broker-dealers and banks.
Any such loan must be continuously secured by collateral in cash or cash
equivalents maintained on a current basis in an amount at least equal to the
market value of the securities loaned by the Fund. The Fund would continue to
receive the equivalent of the interest or dividends paid by the issuer on the
securities loaned, and would also receive an additional return that may be in
the form of a fixed fee or a percentage of the collateral. The Fund may pay
reasonable fees to persons unaffiliated with the Fund for services in arranging
these loans. The Fund would have the right to call the loan and obtain the
securities loaned at any time on notice of not more than five business days. The
Fund would not have the right to vote the securities during the existence of the
loan but would call the loan to permit voting of the securities, if, in
Calamos's judgment, a material event requiring a shareholder vote would
otherwise occur before the loan was repaid. In the event of bankruptcy or other
default of the borrower, the Fund could experience both delays in liquidating
the loan collateral or recovering the loaned securities and losses, including
(a) possible decline in the value of the collateral or in the value of the
securities loaned during the period while the Fund seeks to enforce its rights
thereto, (b) possible subnormal levels of income and lack of access to income
during this period, and (c) expenses of enforcing its rights.

OPTIONS ON SECURITIES, INDEXES AND CURRENCIES

         The Fund may purchase and sell put options and call options on
securities, indexes or foreign currencies in standardized contracts traded on
recognized securities exchanges, boards of trade, or similar entities, or quoted
on the Nasdaq National Market System. The Fund may purchase agreements,
sometimes called cash puts, that may accompany the purchase of a new issue of
bonds from a dealer.

         An option on a security (or index) is a contract that gives the
purchaser (holder) of the option, in return for a premium, the right to buy from
(call) or sell to (put) the seller (writer) of the option the security
underlying the option (or the cash value of the index) at a specified exercise
price at any time during the term of the option (normally not exceeding nine
months). The writer of an option on an individual security or on a foreign
currency has the obligation upon exercise of the option to deliver the
underlying security or foreign currency upon payment of the exercise price or to
pay the exercise price upon delivery of the underlying security or foreign
currency. Upon exercise, the writer of an option on an index is obligated to pay
the difference between the cash value of the index and the exercise price



                                      S-10


multiplied by the specified multiplier for the index option. (An index is
designed to reflect specified facets of a particular financial or securities
market, a specific group of financial instruments or securities, or certain
economic indicators.)

         The Fund will write call options and put options only if they are
"covered." For example, in the case of a call option on a security, the option
is "covered" if the Fund owns the security underlying the call or has an
absolute and immediate right to acquire that security without additional cash
consideration (or, if additional cash consideration is required, cash or cash
equivalents in such amount are held in a segregated account by its custodian)
upon conversion or exchange of other securities held in its portfolio.

         If an option written by the Fund expires, the Fund realizes a capital
gain equal to the premium received at the time the option was written. If an
option purchased by the Fund expires, the Fund realizes a capital loss equal to
the premium paid.

         Prior to the earlier of exercise or expiration, an option may be closed
out by an offsetting purchase or sale of an option of the same series (type,
exchange, underlying security or index, exercise price and expiration). There
can be no assurance, however, that a closing purchase or sale transaction can be
effected when the Fund desires.

         The Fund will realize a capital gain from a closing purchase
transaction if the cost of the closing option is less than the premium received
from writing the option, or, if it is more, the Fund will realize a capital
loss. If the premium received from a closing sale transaction is more than the
premium paid to purchase the option, the Fund will realize a capital gain or, if
it is less, the Fund will realize a capital loss. The principal factors
affecting the market value of a put or a call option include supply and demand,
interest rates, the current market price of the underlying security or index in
relation to the exercise price of the option, the volatility of the underlying
security or index, and the time remaining until the expiration date.

         A put or call option purchased by the Fund is an asset of the Fund,
valued initially at the premium paid for the option. The premium received for an
option written by the Fund is recorded as a deferred credit. The value of an
option purchased or written is marked-to-market daily and is valued at the
closing price on the exchange on which it is traded or, if not traded on an
exchange or no closing price is available, at the mean between the last bid and
asked prices.

RISKS ASSOCIATED WITH OPTIONS

         There are several risks associated with transactions in options. For
example, there are significant differences between the securities markets, the
currency markets and the options markets that could result in an imperfect
correlation among these markets, causing a given transaction not to achieve its
objectives. A decision as to whether, when and how to use options involves the
exercise of skill and judgment, and even a well-conceived transaction may be
unsuccessful to some degree because of market behavior or unexpected events.

         There can be no assurance that a liquid market will exist when the Fund
seeks to close out an option position. If the Fund were unable to close out an
option that it has purchased on a security, it would have to exercise the option
in order to realize any profit or the option would expire and become worthless.
If the Fund were unable to close out a covered call option that it had written
on a security, it would not be able to sell the underlying security until the
option expired. As the writer of a covered call option on a security, the Fund
foregoes, during the option's life, the opportunity to profit from increases in
the market value of the security covering the call option above the sum of the
premium and the exercise price of the call. As the writer of a covered call
option on a foreign currency, the Fund foregoes, during the option's life, the
opportunity to profit from currency appreciation.

                                      S-11


         If trading were suspended in an option purchased or written by the
Fund, the Fund would not be able to close out the option. If restrictions on
exercise were imposed, the Fund might not be able to exercise an option it has
purchased.

FUTURES CONTRACTS AND OPTIONS ON FUTURES CONTRACTS

         The Fund may use interest rate futures contracts, index futures
contracts and foreign currency futures contracts. An interest rate, index or
foreign currency futures contract provides for the future sale by one party and
purchase by another party of a specified quantity of a financial instrument or
the cash value of an index(1) at a specified price and time. A public market
exists in futures contracts covering a number of indexes (including, but not
limited to: the Standard & Poor's 500 Index, the Russell 2000 Index, the Value
Line Composite Index, and the New York Stock Exchange Composite Index) as well
as financial instruments (including, but not limited to: U.S. Treasury bonds,
U.S. Treasury notes, Eurodollar certificates of deposit and foreign currencies).
Other index and financial instrument futures contracts are available and it is
expected that additional futures contracts will be developed and traded.

         The Fund may purchase and write call and put futures options. Futures
options possess many of the same characteristics as options on securities,
indexes and foreign currencies (discussed above). A futures option gives the
holder the right, in return for the premium paid, to assume a long position
(call) or short position (put) in a futures contract at a specified exercise
price at any time during the period of the option. Upon exercise of a call
option, the holder acquires a long position in the futures contract and the
writer is assigned the opposite short position. In the case of a put option, the
opposite is true. The Fund might, for example, use futures contracts to hedge
against or gain exposure to fluctuations in the general level of stock prices,
anticipated changes in interest rates or currency fluctuations that might
adversely affect either the value of the Fund's securities or the price of the
securities that the Fund intends to purchase. Although other techniques could be
used to reduce or increase the Fund's exposure to stock price, interest rate and
currency fluctuations, the Fund may be able to achieve its desired exposure more
effectively and perhaps at a lower cost by using futures contracts and futures
options.

         The Fund will only enter into futures contracts and futures options
that are standardized and traded on an exchange, board of trade or similar
entity, or quoted on an automated quotation system.

         The success of any futures transaction depends on the investment
manager correctly predicting changes in the level and direction of stock prices,
interest rates, currency exchange rates and other factors. Should those
predictions be incorrect, the Fund's return might have been better had the
transaction not been attempted; however, in the absence of the ability to use
futures contracts, the investment manager might have taken portfolio actions in
anticipation of the same market movements with similar investment results, but,
presumably, at greater transaction costs. When a purchase or sale of a futures
contract is made by the Fund, the Fund is required to deposit with its custodian
(or broker, if legally permitted) a specified amount of cash or U.S. Government
securities or other securities acceptable to the broker ("initial margin"). The
margin required for a futures contract is set by the exchange on which the
contract is traded and may be modified during the term of the contract, although
the Fund's broker may require margin deposits in excess of the minimum required
by the exchange. The initial margin is in the nature of a performance bond or
good faith deposit on the futures contract, which is returned to the Fund upon
termination of the contract, assuming all contractual obligations have been
satisfied. The Fund expects to earn interest income on its initial margin
deposits. A futures contract held by the Fund is valued daily at

------------------
(1) A futures contract on an index is an agreement pursuant to which two parties
agree to take or make delivery of an amount of cash equal to the difference
between the value of the index at the close of the last trading day of the
contract and the price at which the index contract was originally written.
Although the value of a securities index is a function of the value of certain
specified securities, no physical delivery of those securities is made.



                                      S-12




the official settlement price of the exchange on which it is traded. Each day
the Fund pays or receives cash, called "variation margin," equal to the daily
change in value of the futures contract. This process is known as
"marking-to-market." Variation margin paid or received by the Fund does not
represent a borrowing or loan by the Fund but is instead settlement between the
Fund and the broker of the amount one would owe the other if the futures
contract had expired at the close of the previous day. In computing daily net
asset value, the Fund will mark-to-market its open futures positions.

         The Fund is also required to deposit and maintain margin with respect
to put and call options on futures contracts written by it. Such margin deposits
will vary depending on the nature of the underlying futures contract (and the
related initial margin requirements), the current market value of the option and
other futures positions held by the Fund.

         Although some futures contracts call for making or taking delivery of
the underlying securities, usually these obligations are closed out prior to
delivery by offsetting purchases or sales of matching futures contracts (same
exchange, underlying security or index, and delivery month). If an offsetting
purchase price is less than the original sale price, the Fund engaging in the
transaction realizes a capital gain, or if it is more, the Fund realizes a
capital loss. Conversely, if an offsetting sale price is more than the original
purchase price, the Fund engaging in the transaction realizes a capital gain, or
if it is less, the Fund realizes a capital loss. The transaction costs must also
be included in these calculations.

RISKS ASSOCIATED WITH FUTURES

         There are several risks associated with the use of futures contracts
and futures options. A purchase or sale of a futures contract may result in
losses in excess of the amount invested in the futures contract. In trying to
increase or reduce market exposure, there can be no guarantee that there will be
a correlation between price movements in the futures contract and in the
portfolio exposure sought. In addition, there are significant differences
between the securities and futures markets that could result in an imperfect
correlation between the markets, causing a given transaction not to achieve its
objectives. The degree of imperfection of correlation depends on circumstances
such as: variations in speculative market demand for futures, futures options
and the related securities, including technical influences in futures and
futures options trading and differences between the securities markets and the
securities underlying the standard contracts available for trading. For example,
in the case of index futures contracts, the composition of the index, including
the issuers and the weighing of each issue, may differ from the composition of
the Fund's portfolio, and, in the case of interest rate futures contracts, the
interest rate levels, maturities and creditworthiness of the issues underlying
the futures contract may differ from the financial instruments held in the
Fund's portfolio. A decision as to whether, when and how to use futures
contracts involves the exercise of skill and judgment, and even a well-conceived
transaction may be unsuccessful to some degree because of market behavior or
unexpected stock price or interest rate trends.

         Futures exchanges may limit the amount of fluctuation permitted in
certain futures contract prices during a single trading day. The daily limit
establishes the maximum amount that the price of a futures contract may vary
either up or down from the previous day's settlement price at the end of the
current trading session. Once the daily limit has been reached in a futures
contract subject to the limit, no more trades may be made on that day at a price
beyond that limit. The daily limit governs only price movements during a
particular trading day and therefore does not limit potential losses because the
limit may work to prevent the liquidation of unfavorable positions. For example,
futures prices have occasionally moved to the daily limit for several
consecutive trading days with little or no trading, thereby preventing prompt
liquidation of positions and subjecting some holders of futures contracts to
substantial losses. Stock index futures contracts are not normally subject to
such daily price change limitations.

         There can be no assurance that a liquid market will exist at a time
when the Fund seeks to close out a futures or futures option position. The Fund
would be exposed to possible loss on the position


                                      S-13


during the interval of inability to close, and would continue to be required to
meet margin requirements until the position is closed. In addition, many of the
contracts discussed above are relatively new instruments without a significant
trading history. As a result, there can be no assurance that an active secondary
market will develop or continue to exist.

LIMITATIONS ON OPTIONS AND FUTURES

         If other options, futures contracts or futures options of types other
than those described herein are traded in the future, the Fund may also use
those investment vehicles, provided the Board of Trustees determines that their
use is consistent with the Fund's investment objective.

         When purchasing a futures contract or writing a put option on a futures
contract, the Fund must maintain with its custodian (or broker, if legally
permitted) cash or cash equivalents (including any margin) equal to the market
value of such contract. When writing a call option on a futures contract, the
Fund similarly will maintain with its custodian cash or cash equivalents
(including any margin) equal to the amount by which such option is in-the-money
until the option expires or is closed by the Fund.

         The Fund may not maintain open short positions in futures contracts,
call options written on futures contracts or call options written on indexes if,
in the aggregate, the market value of all such open positions exceeds the
current value of the securities in its portfolio, plus or minus unrealized gains
and losses on the open positions, adjusted for the historical relative
volatility of the relationship between the portfolio and the positions. For this
purpose, to the extent the Fund has written call options on specific securities
in its portfolio, the value of those securities will be deducted from the
current market value of the securities portfolio.

         In order to comply with Commodity Futures Trading Commission Regulation
4.5 and thereby avoid being deemed a "commodity pool operator," the Fund will
use commodity futures or commodity options contracts solely for bona fide
hedging purposes within the meaning and intent of Regulation 1.3(z), or, with
respect to positions in commodity futures and commodity options contracts that
do not come within the meaning and intent of 1.3(z), the aggregate initial
margin and premiums required to establish such positions will not exceed 5% of
the fair market value of the assets of the Fund, after taking into account
unrealized profits and unrealized losses on any such contracts it has entered
into. In the case of an option that is in-the-money at the time of purchase, the
in-the-money amount (as defined in Section 190.01(x) of the Commission
Regulations) may be excluded in computing such 5%.

WARRANTS

         The Fund may invest in warrants. A warrant is a right to purchase
common stock at a specific price (usually at a premium above the market value of
the underlying common stock at time of issuance) during a specified period of
time. A warrant may have a life ranging from less than a year to twenty years or
longer, but a warrant becomes worthless unless it is exercised or sold before
expiration. In addition, if the market price of the common stock does not exceed
the warrant's exercise price during the life of the warrant, the warrant will
expire worthless. Warrants have no voting rights, pay no dividends and have no
rights with respect to the assets of the corporation issuing them. The
percentage increase or decrease in the value of a warrant may be greater than
the percentage increase or decrease in the value of the underlying common stock.

PORTFOLIO TURNOVER

         Although the Fund does not purchase securities with a view to rapid
turnover, there are no limitations on the length of time that portfolio
securities must be held. Portfolio turnover can occur for a number of reasons,
including calls for redemption, general conditions in the securities markets,
more


                                      S-14


favorable investment opportunities in other securities, or other factors
relating to the desirability of holding or changing a portfolio investment. The
portfolio turnover rates may vary greatly from year to year. A high rate of
portfolio turnover in the Fund would result in increased transaction expense,
which must be borne by that Fund. High portfolio turnover may also result in the
realization of capital gains or losses and, to the extent net short-term capital
gains are realized, any distributions resulting from such gains will be
considered ordinary income for federal income tax purposes.

SHORT SALES

         The Fund may attempt to hedge against market risk and to enhance income
by selling short "against the box," that is: (1) entering into short sales of
securities that it currently has the right to acquire through the conversion or
exchange of other securities that it owns, or to a lesser extent, entering into
short sales of securities that it currently owns; and (2) entering into
arrangements with the broker-dealers through which such securities are sold
short to receive income with respect to the proceeds of short sales during the
period the Fund's short positions remain open. The Fund may make short sales of
securities only if at all times when a short position is open the Fund owns an
equal amount of such securities or securities convertible into or exchangeable
for, without payment of any further consideration, securities of the same issue
as, and equal in amount to, the securities sold short.

         In a short sale against the box, the Fund does not deliver from its
portfolio the securities sold and does not receive immediately the proceeds from
the short sale. Instead, the Fund borrows the securities sold short from a
broker-dealer through which the short sale is executed, and the broker-dealer
delivers such securities, on behalf of the Fund, to the purchaser of such
securities. Such broker-dealer is entitled to retain the proceeds from the short
sale until the Fund delivers to such broker-dealer the securities sold short. In
addition, the Fund is required to pay to the broker-dealer the amount of any
dividends paid on shares sold short. Finally, to secure its obligation to
deliver to such broker-dealer the securities sold short, the Fund must deposit
and continuously maintain in a separate account with the Fund's custodian an
equivalent amount of the securities sold short or securities convertible into or
exchangeable for such securities without the payment of additional
consideration. The Fund is said to have a short position in the securities sold
until it delivers to the broker-dealer the securities sold, at which time the
Fund receives the proceeds of the sale. Because the Fund ordinarily will want to
continue to hold securities in its portfolio that are sold short, the Fund will
normally close out a short position by purchasing on the open market and
delivering to the broker-dealer an equal amount of the securities sold short,
rather than by delivering portfolio securities.

         A short sale works the same way, except that the Fund places in the
segregated account cash or U.S. government securities equal in value to the
difference between (i) the market value of the securities sold short at the time
they were sold short and (ii) any cash or U.S. government securities required to
be deposited with the broker as collateral. In addition, so long as the short
position is open, the Fund must adjust daily the value of the segregated account
so that the amount deposited in it, plus any amount deposited with the broker as
collateral, will equal the current market value of the security sold short.
However, the value of the segregated account may not be reduced below the point
at which the segregated account, plus any amount deposited with the broker, is
equal to the market value of the securities sold short at the time they were
sold short.

         Short sales may protect the Fund against the risk of losses in the
value of its portfolio securities because any unrealized losses with respect to
such portfolio securities should be wholly or partially offset by a
corresponding gain in the short position. However, any potential gains in such
portfolio securities should be wholly or partially offset by a corresponding
loss in the short position. The extent to which such gains or losses are offset
will depend upon the amount of securities sold short relative to the amount


                                      S-15


the Fund owns, either directly or indirectly, and, in the case where the Fund
owns convertible securities, changes in the conversion premium.

         Short sale transactions of the Fund involve certain risks. In
particular, the imperfect correlation between the price movements of the
convertible securities and the price movements of the underlying common stock
being sold short creates the possibility that losses on the short sale hedge
position may be greater than gains in the value of the portfolio securities
being hedged. In addition, to the extent that the Fund pays a conversion premium
for a convertible security, the Fund is generally unable to protect against a
loss of such premium pursuant to a short sale hedge. In determining the number
of shares to be sold short against the Fund's position in the convertible
securities, the anticipated fluctuation in the conversion premiums is
considered. The Fund will also incur transaction costs in connection with short
sales. Certain provisions of the Internal Revenue Code (and related Treasury
Regulations thereunder) may limit the degree to which the Fund is able to enter
into short sales and other transactions with similar effects without triggering
adverse tax consequences, which limitations might impair the Fund's ability to
achieve its investment objective. See "U.S. Federal Income Tax Matters."

         In addition to enabling the Fund to hedge against market risk, short
sales may afford the Fund an opportunity to earn additional current income to
the extent the Fund is able to enter into arrangements with broker-dealers
through which the short sales are executed to receive income with respect to the
proceeds of the short sales during the period the Fund's short positions remain
open.

"WHEN-ISSUED" AND DELAYED DELIVERY SECURITIES AND REVERSE REPURCHASE AGREEMENTS

         The Fund may purchase securities on a when-issued or delayed-delivery
basis. Although the payment and interest terms of these securities are
established at the time the Fund enters into the commitment, the securities may
be delivered and paid for a month or more after the date of purchase, when their
value may have changed. The Fund makes such commitments only with the intention
of actually acquiring the securities, but may sell the securities before
settlement date if Calamos deems it advisable for investment reasons. The Fund
may utilize spot and forward foreign currency exchange transactions to reduce
the risk inherent in fluctuations in the exchange rate between one currency and
another when securities are purchased or sold on a when-issued or
delayed-delivery basis.

         The Fund may enter into reverse repurchase agreements with banks and
securities dealers. A reverse repurchase agreement is a repurchase agreement in
which the Fund is the seller of, rather than the investor in, securities and
agrees to repurchase them at an agreed-upon time and price. Use of a reverse
repurchase agreement may be preferable to a regular sale and later repurchase of
securities because it avoids certain market risks and transaction costs.

         At the time when the Fund enters into a binding obligation to purchase
securities on a when-issued basis or enters into a reverse repurchase agreement,
liquid assets (cash, U.S. Government securities or other "high-grade" debt
obligations) of the Fund having a value at least as great as the purchase price
of the securities to be purchased will be segregated on the books of the Fund
and held by the custodian throughout the period of the obligation. The use of
these investment strategies may increase net asset value fluctuation.

ILLIQUID SECURITIES

         The Fund may invest without limitation in securities that have not been
registered for public sale, but that are eligible for purchase and sale by
certain qualified institutional buyers. Although many of the Rule 144A
Securities in which the Fund invests may be, in the view of Calamos, liquid if
qualified institutional buyers are unwilling to purchase these Rule 144A
Securities, they may be illiquid. The Fund may invest without limit in illiquid
securities. Illiquid securities may be difficult to dispose of at a fair


                                      S-16


price at the times when the Fund believes it is desirable to do so. The market
price of illiquid securities generally is more volatile than that of more liquid
securities, which may adversely affect the price that the Fund pays for or
recovers upon the sale of illiquid securities. Illiquid securities are also more
difficult to value and Calamos's judgment may play a greater role in the
valuation process. Investment of the Fund's assets in illiquid securities may
restrict the Fund's ability to take advantage of market opportunities. The risks
associated with illiquid securities may be particularly acute in situations in
which the Fund's operations require cash and could result in the Fund borrowing
to meet its short-term needs or incurring losses on the sale of illiquid
securities.

         The Fund may invest without limit in bonds, corporate loans,
convertible securities, preferred stocks and other securities that lack a
secondary trading market or are otherwise considered illiquid. Liquidity of a
security relates to the ability to easily dispose of the security and the price
to be obtained upon disposition of the security, which may be less than would be
obtained for a comparable more liquid security. Such investments may affect the
Fund's ability to realize the net asset value in the event of a voluntary or
involuntary liquidation of its assets.

TEMPORARY INVESTMENTS

         The Fund may make temporary investments without limitation when Calamos
determines that a defensive position is warranted. Such investments may be in
money market instruments, consisting of obligations of, or guaranteed as to
principal and interest by, the U.S. Government or its agencies or
instrumentalities; certificates of deposit, bankers' acceptances and other
obligations of domestic banks having total assets of at least $500 million and
that are regulated by the U.S. Government, its agencies or instrumentalities;
commercial paper rated in the highest category by a recognized rating agency;
and repurchase agreements.

REPURCHASE AGREEMENTS

         As part of its strategy for the temporary investment of cash, the Fund
may enter into "repurchase agreements" pertaining to U.S. Government securities
with member banks of the Federal Reserve System or primary dealers (as
designated by the Federal Reserve Bank of New York) in such securities. A
repurchase agreement arises when the Fund purchases a security and
simultaneously agrees to resell it to the vendor at an agreed upon future date.
The resale price is greater than the purchase price, reflecting an agreed upon
market rate of return that is effective for the period of time the Fund holds
the security and that is not related to the coupon rate on the purchased
security. Such agreements generally have maturities of no more than seven days
and could be used to permit the Fund to earn interest on assets awaiting long
term investment. The Fund requires continuous maintenance by the custodian for
the Fund's account in the Federal Reserve/Treasury Book Entry System of
collateral in an amount equal to, or in excess of, the market value of the
securities that are the subject of a repurchase agreement. Repurchase agreements
maturing in more than seven days are considered illiquid securities. In the
event of a bankruptcy or other default of a seller of a repurchase agreement,
the Fund could experience both delays in liquidating the underlying security and
losses, including: (a) possible decline in the value of the underlying security
during the period while the Fund seeks to enforce its rights thereto; (b)
possible subnormal levels of income and lack of access to income during this
period; and (c) expenses of enforcing its rights.

PREFERRED SHARES

         The Fund may invest in preferred shares. The preferred shares that the
Fund will invest in will typically be convertible securities. Preferred shares
are equity securities, but they have many characteristics of fixed income
securities, such as a fixed dividend payment rate and/or a liquidity preference
over the issuer's common shares.

                                      S-17


REAL ESTATE INVESTMENT FUNDS ("REITS") AND ASSOCIATED RISK FACTORS

         REITs are pooled investment vehicles which invest primarily in income
producing real estate or real estate related loans or interests. REITs are
generally classified as equity REITs, mortgage REITs or a combination of equity
and mortgage REITs. Equity REITs invest the majority of their assets directly in
real property and derive income primarily from the collection of rents. Equity
REITs can also realize capital gains by selling properties that have appreciated
in value. Mortgage REITs invest the majority of their assets in real estate
mortgages and derive income from the collection of interest payments. REITs are
not taxed on income distributed to shareholders provided they comply with the
applicable requirements of the Internal Revenue Code of 1986, as amended (the
"Code"). The Fund will indirectly bear its proportionate share of any management
and other expenses paid by REITs in which it invests in addition to the expenses
paid by the Fund. Debt securities issued by REITs are, for the most part,
general and unsecured obligations and are subject to risks associated with
REITs.

         Investing in REITs involves certain unique risks in addition to those
risks associated with investing in the real estate industry in general. An
equity REIT may be affected by changes in the value of the underlying properties
owned by the REIT. A mortgage REIT may be affected by changes in interest rates
and the ability of the issuers of its portfolio mortgages to repay their
obligations. REITs are dependent upon the skills of their managers and are not
diversified. REITs are generally dependent upon maintaining cash flows to repay
borrowings and to make distributions to shareholders and are subject to the risk
of default by lessees or borrowers. REITs whose underlying assets are
concentrated in properties used by a particular industry, such as health care,
are also subject to risks associated with such industry.

         REITs (especially mortgage REITs) are also subject to interest rate
risks. When interest rates decline, the value of a REIT's investment in fixed
rate obligations can be expected to rise. Conversely, when interest rates rise,
the value of a REIT's investment in fixed rate obligations can be expected to
decline. If the REIT invests in adjustable rate mortgage loans the interest
rates on which are reset periodically, yields on a REIT's investments in such
loans will gradually align themselves to reflect changes in market interest
rates. This causes the value of such investments to fluctuate less dramatically
in response to interest rate fluctuations than would investments in fixed rate
obligations.

         REITs may have limited financial resources, may trade less frequently
and in a limited volume and may be subject to more abrupt or erratic price
movements than larger company securities. Historically REITs have been more
volatile in price than the larger capitalization stocks included in Standard &
Poor's 500 Stock Index.

OTHER INVESTMENT COMPANIES

         The Fund may invest in the securities of other investment companies to
the extent that such investments are consistent with the Fund's investment
objective and policies and permissible under the Investment Company Act of 1940,
as amended (the "1940 Act"). Under the 1940 Act, the Fund may not acquire the
securities of other domestic or non-U.S. investment companies if, as a result,
(i) more than 10% of the Fund's total assets would be invested in securities of
other investment companies, (ii) such purchase would result in more than 3% of
the total outstanding voting securities of any one investment company being held
by the Fund, or (iii) more than 5% of the Fund's total assets would be invested
in any one investment company. These limitations do not apply to the purchase of
shares of any investment company in connection with a merger, consolidation,
reorganization or acquisition of substantially all the assets of another
investment company.

         The Fund, as a holder of the securities of other investment companies,
will bear its pro rata portion of the other investment companies' expenses,
including advisory fees. These expenses are in addition to the direct expenses
of the Fund's own operations.

                                      S-18


                             INVESTMENT RESTRICTIONS

         The following are the Fund's fundamental investment restrictions. These
restrictions may not be changed without the approval of the holders of a
majority of the Fund's outstanding voting securities (which for this purpose and
under the 1940 Act means the lesser of (i) 67% of the common shares represented
at a meeting at which more than 50% of the outstanding common shares are
represented or (ii) more than 50% of the outstanding common shares). If the Fund
were to issue a class of preferred shares, the investment restrictions could not
be changed without the approval of a majority of the outstanding common and
preferred shares, voting together as a class, and the approval of a majority of
the outstanding preferred shares, voting separately by class.

         The Fund may not:

         (1)      Issue senior securities, except as permitted by the 1940 Act
                  and the rules and interpretive positions of the SEC
                  thereunder.

         (2)      Borrow money, except as permitted by the 1940 Act and the
                  rules and interpretive positions of the SEC thereunder.

         (3)      Invest in real estate, except that the Fund may invest in
                  securities of issuers that invest in real estate or interests
                  therein, securities that are secured by real estate or
                  interests therein, securities of real estate investment funds
                  and mortgage-backed securities.

         (4)      Make loans, except by the purchase of debt obligations, by
                  entering into repurchase agreements or through the lending of
                  portfolio securities and as otherwise permitted by the 1940
                  Act and the rules and interpretive positions of the SEC
                  thereunder.

         (5)      Invest in physical commodities or contracts relating to
                  physical commodities.

         (6)      Act as an underwriter, except as it may be deemed to be an
                  underwriter in a sale of securities held in its portfolio.

         (7)      Make any investment inconsistent with the Fund's
                  classification as a diversified investment company under the
                  1940 Act and the rules and interpretive positions of the SEC
                  thereunder.

         (8)      Concentrate its investments in securities of companies in any
                  particular industry as defined in the 1940 Act and the rules
                  and interpretive positions of the SEC thereunder.

         All other investment policies of the Fund are considered
non-fundamental and may be changed by the Board of Trustees without prior
approval of the Fund's outstanding voting shares.

         Under the 1940 Act, the Fund may invest up to 10% of its total assets
in the aggregate in shares of other investment companies and up to 5% of its
total assets in any one investment company, provided the investment does not
represent more than 3% of the voting stock of the acquired investment company at
the time such shares are purchased. As a shareholder in any investment company,
the Fund will bear its ratable share of that investment company's expenses, and
would remain subject to payment of the Fund's advisory fees and other expenses
with respect to assets so invested. Holders of common shares would therefore be
subject to duplicative expenses to the extent the Fund invests in other
investment companies. In addition, the securities of other investment companies
may also be leveraged and will therefore be subject to the same leverage risks
described herein and in the Prospectus. As described in the prospectus in the
section entitled "Risks," the net asset value and market value of leveraged
shares will be


                                      S-19


more volatile and the yield to shareholders will tend to fluctuate more than the
yield generated by unleveraged shares.

         In addition, to comply with federal income tax requirements for
qualification as a "regulated investment company," the Fund's investments will
be limited by both an income and an asset test. See "U.S. Federal Income Tax
Matters."

         As a non-fundamental policy, the Fund may not issue preferred shares,
borrow money or issue debt securities in an aggregate amount exceeding 33?% of
the Fund's total assets.

                                      S-21


------------------
* John P. Calamos and Nick P. Calamos are trustees who are "interested persons"
of the Trust as defined in the Investment Company Act of 1940 (the "1940 Act")
because of their position with Calamos. Weston W. Marsh is a trustee who is an
"interested person" of the Trust as defined in the 1940 Act because he is a
partner at a law firm that has performed work for one or more principal
underwriters. In addition, Mr. Marsh is a partner at a law firm that has
performed work for John P. Calamos, the chief executive and a controlling person
of Calamos (such work was not with respect to 1940 Act or Investment Advisers
Act of 1940 matters). Upon the advice of counsel to the Trust, the Trust does
not believe that Mr. Marsh is an "interested person" of Calamos.

         The Trustees of the Fund are also Trustees of Calamos Advisors Trust
and Calamos Investment Trust, both open-end investment companies advised by
Calamos.

         The Fund's Board of Trustees consists of seven members. The term of one
class expires each year commencing with the first annual meeting following this
public offering and no term shall continue for more than three years after the
applicable election. The terms of Joe F. Hanauer and John E. Neal expire at the
first annual meeting following this public offering, the terms of Nick P.
Calamos and Richard J. Dowen expire at the second annual meeting, and the terms
of John P. Calamos, Weston W. Marsh and William Rybak expire at the third annual
meeting. Subsequently, each class of Trustees will stand for election at the
conclusion of its respective term. Such classification may prevent replacement
of a majority of the Trustees for up to a two-year period.

         COMMITTEES OF THE BOARD OF TRUSTEES. The Fund's Board of Trustees
currently has three standing committees:

              EXECUTIVE COMMITTEE. Messrs. John Calamos and Nick Calamos are
         members of the Executive Committee, which has authority during
         intervals between meetings of the Board of Trustees to exercise the
         powers of the board, with certain exceptions.

              AUDIT COMMITTEE. Messrs. Dowen, Hanauer, Neal and Rybak serve on
         the Audit Committee. The Audit Committee recommends independent
         auditors to the trustees, monitors the auditors' performance, reviews
         the results of the Fund's audit, and responds to other matters deemed
         appropriate by the Board of Trustees.

                  GOVERNANCE COMMITTEE. Messrs. Dowen, Hanauer, Neal, Marsh and
         Rybak serve on the Governance Committee. The Governance Committee
         oversees the independence and effective functioning of the Board of
         Trustees and endeavors to be informed about good practices for fund
         boards. The members of the Governance Committee who are not interested
         persons of the Fund make recommendations to the Board of Trustees
         regarding candidates for election as non-interested Trustees. The
         Governance Committee will not consider shareholder recommendations
         regarding candidates for election as Trustees.

         The Fund's Agreement and Declaration of Trust provides that the Fund
will indemnify the Trustees and officers against liabilities and expenses
incurred in connection with any claim in which they may be involved because of
their offices with the Fund, unless it is determined in the manner specified in
the Agreement and Declaration of Trust that they have not acted in good faith in
the reasonable belief that their actions were in the best interests of the Fund
or that such indemnification would relieve any officer


                                      S-22


or Trustee of any liability to the Fund or its shareholders by reason of willful
misfeasance, bad faith, gross negligence or reckless disregard of his or her
duties.

COMPENSATION OF OFFICERS AND TRUSTEES

         The Fund pays no salaries or compensation to any of its officers or to
the Trustees who are affiliated persons of Calamos.

             OWNERSHIP OF SHARES OF THE FUND AND OTHER CALAMOS FUNDS

         The following table indicates the value of shares that each Trustee

         The Fund and Calamos have adopted a code of ethics under Rule 17j-1 of

personal securities transactions, including transactions in securities that the
Fund may purchase, sell or hold, subject to requirements and restrictions set
forth in the code of ethics of Calamos and CFS. The code of ethics contains
provisions and requirements designed to identify and address certain conflicts
of interest between personal investment activities of Calamos and CFS employees
and the interests of investment advisory clients such as the Fund. Among other
things, the code of ethics prohibits certain types of transactions absent prior
approval, imposes time periods during which personal transaction of duplicate
broker confirmations and statements and quarterly reporting of securities

research analysts and others involved in the investment advisory process.
Exceptions to these and other provisions of the code of ethics may be granted in
particular circumstances after review by appropriate personnel.

(iii) assisting in the preparation and making of filings with the Commission and

         Under the investment management agreement, the Fund pays to Calamos a
fee based on the average weekly managed assets that is accrued daily and paid on
a monthly basis. The fee paid by the Fund is at the annual rate of 0.80% of
managed assets. Because the fees paid to Calamos are determined


                                      S-24


on the basis of the Fund's managed assets, Calamos's interest in determining
whether to leverage the Fund may differ from the interests of the Fund.

         For the first eight years of the Fund's operations, Calamos has
contractually agreed to waive its management fee in the annual amounts, and for
the time periods, set forth below:

         Unless earlier terminated as described below, the investment management
agreement will remain in effect until August 1, 2003 and will continue in effect
from year to year thereafter so long as such continuation is approved at least
annually by (1) the board of trustees or the vote of a majority of the
outstanding voting securities (as defined in the 1940 Act) of the Fund, and (2)
a majority of the trustees


                                      S-25


who are not interested persons of any party to the investment management
agreement, cast in person at a meeting called for the purpose of voting on such
approval. The investment management agreement may be terminated at any time,
without penalty, by either the Fund or Calamos upon 60 days' written notice, and
is automatically terminated in the event of its assignment as defined in the
1940 Act.

         FACTORS CONSIDERED BY THE INDEPENDENT TRUSTEES IN APPROVING THE
INVESTMENT MANAGEMENT AGREEMENT. The Fund's investment management agreement is
required to be approved before it is entered into and thereafter annually both
by the Board of Trustees and a majority of the Independent Trustees voting
separately. The Independent Trustees have determined that the terms of the
Fund's investment management agreement are fair and reasonable and that the
agreement is in the Fund's best interests. The Independent Trustees believe that
the investment management agreement will enable the Fund to enjoy high quality
investment management services at a cost which they deem appropriate, reasonable
and in the best interests of the Fund. In making such determinations, the
Independent Trustees relied upon the assistance of counsel to the Independent
Trustees.

         In evaluating the investment management agreement, the Independent
Trustees considered Calamos, its affiliates and their personnel, operations and
financial condition. The Independent Trustees discussed with representatives of
Calamos the Fund's operations and Calamos's ability to provide advisory and
other services to the Fund. The Independent Trustees also reviewed, among other
things:

         -    the investment performance of other Calamos funds with similar
              investment strategies;

         -    the proposed fees to be charged by Calamos for investment
              management services;

         -    the Fund's projected total operating expenses;

         -    the investment performance, fees and total expenses of investment
              companies with similar objectives and strategies managed by other
              investment advisers;

         -    the experience of the investment advisory and other personnel
              providing services to the Fund and the historical quality of the
              services provided by Calamos; and

         The Independent Trustees considered the following as relevant to their
recommendations: (1) the favorable history, reputation, qualification and
background of Calamos, as well as the qualifications of its personnel and its
financial condition; (2) that the fee and expense ratios of the Fund are
reasonable given the quality of services expected to be provided and are
comparable to the fee and expense ratios of similar investment companies; (3)
the relative performance of other funds managed by Calamos with similar
objectives compared to the results of other comparable investment companies and
unmanaged indices; and (4) other factors that the Independent Trustees deemed
relevant.

         The use of the name "Calamos" in the name of the Fund is pursuant to
licenses granted by Calamos, and the Fund has agreed to change the names to
remove those references if Calamos ceases to act as investment adviser to the
Fund.

         Princeton Administrators, L.P., an affiliate of Merrill Lynch, Pierce,
Fenner & Smith Incorporated, will serve as administrator for the Fund. Calamos
(and not the Fund) will pay the administrator a monthly fee at an annual rate of
0.125% of the Fund's average weekly managed assets, subject to a monthly minimum
fee of $12,500.


                                      S-26

                             PORTFOLIO TRANSACTIONS

         Portfolio transactions on behalf of the Fund effected on stock
exchanges involve the payment of negotiated brokerage commissions. There is
generally no stated commission in the case of securities traded in the
over-the-counter markets, but the price paid by the Fund usually includes an
undisclosed dealer commission or mark-up. In underwritten offerings, the price
paid by the Fund includes a disclosed, fixed commission or discount retained by
the underwriter or dealer.

         In executing portfolio transactions, Calamos uses its best efforts to
obtain for the Fund the most favorable combination of price and execution
available. In seeking the most favorable combination of price and execution,
Calamos considers all factors it deems relevant, including 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 execution capability of the broker-dealer and the quality of service
rendered by the broker-dealer in other transactions.

         The Trustees have determined that portfolio transactions for the Fund
may be executed through Calamos Financial Services, Inc. ("CFS"), an affiliate
of Calamos, if, in the judgment of Calamos, the use of CFS is likely to result
in prices and execution at least as favorable to the Funds as those available
from other qualified brokers and if, in such transactions, CFS charges the Fund
commission rates consistent with those charged by CFS to comparable unaffiliated
customers in similar transactions. The Board of Trustees, including a majority
of the Trustees who are not "interested" trustees, has adopted procedures that
are reasonably designed to provide that any commissions, fees or other
remuneration paid to CFS are consistent with the foregoing standard. The Fund
will not effect principal transactions with CFS.

         Consistent with the Rules of Fair Practice of the National Association
of Securities Dealers, Inc. and subject to seeking the most favorable
combination of net price and execution available and such other policies as the
Trustees may determine, Calamos may consider sales of shares of the Fund as a
factor in the selection of broker-dealers to execute portfolio transactions for
that Fund.

         In allocating the Fund's portfolio brokerage transactions to
unaffiliated broker-dealers, Calamos may take into consideration the research,
analytical, statistical and other information and services provided by the
broker-dealer, such as general economic reports and information, reports or
analyses of particular companies or industry groups, market timing and technical
information, and the availability of the brokerage firm's analysts for
consultation. Although Calamos believes these services have substantial value,
they are considered supplemental to Calamos's own efforts in the performance of
its duties under the management agreement. As permitted by Section 28(e) of the
Securities Exchange Act of 1934 ("1934 Act"), Calamos may cause the Fund to pay
a broker-dealer that provides brokerage and research services an amount of
commission for effecting a securities transaction for the Fund in excess of the
commission that another broker-dealer would have charged for effecting that
transaction if the amount is believed by Calamos to be reasonable in relation to
the value of the overall quality of the brokerage and research services
provided. Other clients of Calamos may indirectly benefit from the provision of
these services to Calamos, and the Fund may indirectly benefit from services
provided to Calamos as a result of transactions for other clients.

                                 NET ASSET VALUE

         Net asset value per share is determined as of the close of regular
session trading on the New York Stock Exchange (usually 4:00 p.m., Eastern
time), on the last business day in each week. Net asset value is calculated by
dividing the value of all of the securities and other assets of the Fund, less
its liabilities (including accrued expenses and indebtedness) and the aggregate
liquidation value of any outstanding





                                      S-27


preferred shares, by the total number of common shares outstanding. Currently,
the net asset values of shares of publicly traded closed-end investment
companies investing in debt securities are published in Barron's, the Monday
edition of The Wall Street Journal and the Monday and Saturday editions of The
New York Times.

         The values of the securities in the Fund are based on market prices
from the primary market in which they are traded. As a general rule, equity
securities listed on a U.S. securities exchange or Nasdaq National Market are
valued at the last quoted sale priced on the day the valuation is made. Bonds
and other fixed-income securities that are traded over the counter and on an
exchange will be valued according to the broadest and most representative
market, and it is expected this will ordinarily be the over-the-counter market.
The foreign securities held by a Fund are traded on exchanges throughout the
world. Trading on these foreign securities exchanges is completed at various
times throughout the day and often does not coincide with the close of trading
on the New York Stock Exchange. The value of foreign securities is determined at
the close of trading of the exchange on which the securities are traded or at
the close of trading on the New York Stock Exchange, whichever is earlier. If
market prices are not readily available or the Fund's valuation methods do not
produce a value reflective of the fair value of the security, securities and
other assets are priced at a fair value as determined by the Board of Trustees
or a committee thereof.

       ADDITIONAL INFORMATION CONCERNING THE AUCTIONS FOR PREFERRED SHARES


GENERAL

         The Depository Trust Company ("DTC") will act as the Securities
Depository with respect to the Preferred Shares. One certificate for all of the
shares of each series will be registered in the name of Cede & Co., as nominee
of the Securities Depository. Such certificate will bear a legend to the effect
that such certificate is issued subject to the provisions restricting transfers
of shares of the Preferred Shares contained in the Statement. The Fund will also
issue stop-transfer instructions to the transfer agent for the Preferred Shares.
Prior to the commencement of the right of holders of the Preferred Shares to
elect a majority of the Fund's Directors, as described under "Description of the
Preferred Shares -- Voting Rights" in the prospectus, Cede & Co. will be the
holder of record of the Preferred Shares and owners of such shares 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, 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 in Preferred Shares, whether
for its own account or as a nominee for another person.

CONCERNING THE AUCTION AGENT

         The auction agent (the "Auction Agent") will act as agent for the Fund
in connection with the auctions of the Preferred Shares (the "Auctions"). In the
absence of willful misconduct or gross 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 between the Fund and the Auction Agent and will not be liable for any
error of judgment made in good faith unless the Auction Agent was grossly
negligent in ascertaining the pertinent facts.

         The Auction Agent may conclusively rely upon, as evidence of the
identities of the holders of the Preferred Shares, the Auction Agent's registry
of holders, and the results of Auctions and notices from any Broker-Dealer (or
other person, if permitted by the Fund) with respect to transfers described
under








                                      S-28


"The Auction -- Secondary Market Trading and Transfers of the Preferred Shares"
in the prospectus 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., New York City time, on the business day preceding such
Auction.

         The Auction Agent may terminate its auction agency agreement with the
Fund 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
has entered into such an agreement with a successor Auction Agent.

BROKER-DEALERS

         The Auction Agent after each Auction for the Preferred Shares 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 the
dividend period of less than one year, or a percentage agreed to by the Fund and
the Broker-Dealer in the case of any Auction immediately preceding a dividend
period of one year or longer, of the purchase price of the Preferred Shares
placed by such Broker-Dealer at such auction. For the purposes of the preceding
sentence, the Preferred Shares will be placed by a Broker-Dealer if such shares
were (a) 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
customers who are beneficial owners or (b) the subject of an order submitted by
such Broker-Dealer that is (i) a submitted bid of an existing holder that
resulted in the existing holder continuing to hold such shares as a result of
the Auction or (ii) a submitted bid of a potential bidder that resulted in the
potential holder purchasing such shares as a result of the auction or (iii) 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 agreement provides that a Broker-Dealer (other than
an affiliate of the Fund) may submit orders in Auctions for its own account,
unless the Trust 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.

                           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.
Instead, the Fund's common shares will trade in the open market at a price that
will be a function of several factors, including dividend levels (which are in
turn affected by expenses), net asset value, call protection, dividend
stability, relative demand for and supply of such shares in the market, general
market and economic conditions and other factors. Because shares of a closed-end
investment company may frequently trade at prices lower than net asset value,
the Fund's Board of Trustees may consider action that might be taken 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, or the
conversion of






                                      S-29



the Fund to an open-end investment company. The Board of Trustees may decide not
to take any of these actions. In addition, there can be no assurance that share
repurchases or tender offers, if undertaken, will reduce market discount.

         Notwithstanding the foregoing, at any time when the Fund's preferred
shares are outstanding, the Fund may not purchase, redeem or otherwise acquire
any of its common shares unless (1) all accumulated preferred shares dividends
have been paid and (2) at the time of such purchase, redemption or acquisition,
the net asset value of the Fund's portfolio (determined after deducting the
acquisition price of the common shares) is at least 200% of the liquidation
value of the outstanding preferred shares (expected to equal the original
purchase price per share plus any accrued and unpaid dividends thereon). Any
service fees incurred in connection with any tender offer made by the Fund will
be borne by the Fund and will not reduce the stated consideration to be paid to
tendering shareholders.

         Subject to its investment restrictions, the Fund may borrow to finance
the repurchase of shares or to make a tender offer. Interest on any borrowings
to finance share repurchase transactions or the accumulation of cash by the Fund
in anticipation of share repurchases or tenders will reduce the Fund's net
income. Any share repurchase, tender offer or borrowing that might be approved
by the Fund's Board of Trustees would have to comply with the Exchange Act, the
1940 Act and the rules and regulations thereunder.

         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 not currently anticipated that the Board of Trustees would
authorize repurchases of 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 New York Stock Exchange, 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 objective 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 adversely affecting the Fund, (b) general
suspension of or limitation on prices for trading securities on the New York
Stock Exchange, (c) declaration of a banking moratorium by federal or state
authorities or any suspension of payment by United States or New York banks, (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 or on the exchange of foreign currency, (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 repurchase by the Fund of its shares at prices below net asset
value will result in an increase in the net asset value of those shares that
remain outstanding. However, there can be no assurance that share repurchases or
tender offers at or below net asset value will result in the Fund's shares
trading at a price equal to their net asset value. Nevertheless, the fact that
the Fund's shares may be the subject of repurchase or tender offers from time to
time, or that the Fund may be converted to an open-end investment company, may
reduce any spread between market price and net asset value that might otherwise
exist.

         In addition, a purchase by the Fund of its common shares will decrease
the Fund's total managed assets which would likely have the effect of increasing
the Fund's expense ratio. Any purchase by the





                                      S-30


Fund of its common shares at a time when preferred shares are outstanding will
increase the leverage applicable to the outstanding common shares then
remaining.

         Before deciding whether to take any action if the common shares trade
below net asset value, the Fund's Board of Trustees would likely consider all
relevant factors, including 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 shares should trade at a discount, the Board
of Trustees may determine that, in the interest of the Fund and its
shareholders, no action should be taken.

                                   TAX MATTERS

         The following is a summary discussion of certain U.S. federal income
tax consequences that may be relevant to a shareholder that acquires, holds
and/or disposes of Preferred Shares of the Fund. This discussion only addresses
U.S. federal income tax consequences to U.S. shareholders who hold their shares
as capital assets and does not address all of the U.S. federal income tax
consequences that may be relevant to particular shareholders in light of their
individual circumstances. This discussion also does not address the tax
consequences to shareholders who are subject to special rules, including,
without limitation, financial institutions, insurance companies, dealers in
securities or foreign currencies, foreign holders, persons who hold their shares
as or in a hedge against currency risk, a constructive sale, or conversion
transaction, holders who are subject to the alternative minimum tax, or
tax-exempt or tax-deferred plans, accounts, or entities. In addition, the
discussion does not address any state, local, or foreign tax consequences. The
discussion reflects applicable tax laws of the United States as of the date of
this prospectus, which tax laws may be changed or subject to new interpretations
by the courts or the Internal Revenue Service ("IRS") retroactively or
prospectively. No attempt is made to present a detailed explanation of all U.S.
federal income tax concerns affecting the Fund and its shareholders, and the
discussion set forth herein does not constitute tax advice. INVESTORS ARE URGED
TO CONSULT THEIR OWN TAX ADVISERS TO DETERMINE THE SPECIFIC TAX CONSEQUENCES TO
THEM OF INVESTING IN THE FUND, INCLUDING THE APPLICABLE FEDERAL, STATE, LOCAL
AND FOREIGN TAX CONSEQUENCES TO THEM AND THE EFFECT OF POSSIBLE CHANGES IN TAX
LAWS.

         The Fund intends to elect to be treated and to qualify each year as a
"regulated investment company" under Subchapter M of the Code so that it will
not pay U.S. federal income tax on income and capital gains distributed to
shareholders. If a Fund qualifies as a regulated investment company and
distributes to its shareholders at least 90% of the sum of (i) its "investment
company taxable income" as that term is defined in the Code (which includes,
among other things, dividends, taxable interest, and the excess of any net
short-term capital gains over net long-term capital losses as reduced by certain
deductible expenses) without regard to the deduction for dividends paid and (ii)
the excess of its gross tax-exempt interest, if any, over certain disallowed
deductions, the Fund will be relieved of U.S. federal income tax on any income
of the Fund, including long-term capital gains, distributed to shareholders.
However, if the Fund retains any investment company income or "net capital gain"
(the excess of net long-term capital gain over net short-term capital loss), it
will be subject to U.S. federal income tax at regular corporate rates on the
amount retained. The Fund intends to distribute at least annually all or
substantially all of its investment company income, net tax-exempt interest, and
net capital gain. If for any taxable year the Fund does not qualify as a
regulated investment company for U.S. federal income tax purposes, it would be
treated as a U.S. corporation subject to U.S. federal income tax and
distributions to its shareholders would not be deductible by the Fund in
computing its taxable income. In addition, in the event that the Fund does not
so qualify, the Fund's distributions, to the extent derived from the Fund's
current or accumulated earnings and profits, would generally constitute ordinary
dividends, which although a portion of such dividends may be eligible for the
corporate dividends received deduction,






                                      S-31


would be taxable to shareholders as ordinary income, even though such
distributions might otherwise, at least in part, have been treated as long-term
capital gains in such shareholder's hands.

         Under the Code, the Fund will be subject to a nondeductible 4% federal
excise tax on a portion of its undistributed ordinary income and capital gains
for any year if it fails to meet certain distribution requirements with respect
to that year. The Fund intends to make distributions in a timely manner and
accordingly does not expect to be subject to this excise tax.

         In order to qualify as a regulated investment company under Subchapter
M of the Code, the Fund must, among other things, derive at least 90% of its
gross income for each taxable year from dividends, interest, payments with
respect to securities loans, gains from the sale or other disposition of stock,
securities or foreign currencies, or other income (including gains from options,
futures and forward contracts) derived with respect to its business of investing
in such stock, securities or currencies (the "90% income test"). For purposes of
the 90% income test, the character of income earned by certain entities in which
the Fund invests that are not treated as corporations (e.g., partnerships) for
U.S. federal income tax purposes will generally pass through to the Fund.
Consequently, the Fund may be required to limit its equity investments in such
entities that earn fee income, rental income or other nonqualifying income.

         In addition to the 90% income test, the Fund must also diversify its
holdings (commonly referred to as the "asset test") so that, at the end of each
quarter of its taxable year (i) at least 50% of the market value of the Fund's
assets is represented by cash and cash items, U.S. government securities,
securities of other regulated investment companies and other securities, with
such other securities of any one issuer limited for the purposes of this
calculation to an amount not greater in value than 5% of the value of the Fund's
total assets and to not more than 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 or securities of other regulated investment companies) or of two or
more issuers controlled by the Fund and engaged in the same, similar or related
trades or businesses.

         Dividends from investment company taxable income, which includes net
investment income, net short-term capital gain in excess of net long-term
capital loss and certain net foreign exchange gains, are taxable as ordinary
income to the extent of the Fund's current and accumulated earnings and profits.
Dividends from net capital gain (net long-term capital gain in excess of net
short-term capital loss), if any, are taxable as long-term capital gains for
U.S. federal income tax purposes without regard to the length of time the
shareholder has held shares of the Fund. The U.S. federal income tax status of
all distributions will be designated by the Fund and reported to the
shareholders annually. Any dividend declared by the Fund as of a record date in
October, November or December and paid during the following January will be
treated for U.S. federal income tax purposes as received by shareholders on
December 31 of the calendar year in which it is declared.


         If the Fund retains any net capital gain, the Fund may designate the
retained amount as undistributed capital gains in a notice to shareholders who,
if subject to U.S. federal income tax on long-term capital gains (i) will be
required to include in income, as long-term capital gain, their proportionate
share of such undistributed amount, and (ii) will be entitled to credit their
proportionate share of the tax paid by the Fund on the undistributed amount
against their U.S. federal income tax liabilities, if any, and to claim refunds
to the extent the credit exceeds such liabilities. For U.S. federal income tax
purposes, the tax basis of shares owned by a shareholder of the Fund will be
increased by the difference between the amount of undistributed net capital gain
included in the shareholder's gross income and the tax deemed paid by the
shareholders.






                                      S-32

         Foreign exchange gains and losses realized by the Fund in connection
with certain transactions involving foreign currency-denominated debt
securities, certain options and futures contracts relating to foreign currency,
foreign currency forward contracts, foreign currencies, or payables or
receivables denominated in a foreign currency are subject to Section 988 of the
Code, which generally causes such gains and losses to be treated as ordinary
income and losses and may affect the amount, timing and character of
distributions to shareholders.

         If the Fund acquires any equity interest (under proposed Treasury
regulations, generally including not only stock but also an option to acquire
stock such as is inherent in a convertible bond) in certain foreign corporations
that receive at least 75% of their annual gross income from passive sources
(such as interest, dividends, certain rents and royalties, or capital gains) or
that hold at least 50% of their assets in investments producing such passive
income ("passive foreign investment companies"), the Fund could be subject to
U.S. federal income tax and additional interest charges on "excess
distributions" received from such companies or on gain from the sale of stock in
such companies, even if all income or gain actually received by the Fund is
timely distributed to its shareholders. The Fund would not be able to pass
through to its shareholders any credit or deduction for such a tax. An election
may generally be available that would ameliorate these adverse tax consequences,
but any such election could require the Fund to recognize taxable income or gain
(subject to tax distribution requirements) without the concurrent receipt of
cash. These investments could also result in the treatment of associated capital
gains as ordinary income. The Fund may limit and/or manage its holdings in
passive foreign investment companies to limit its tax liability or maximize its
return from these investments.

         The Fund may invest to a significant extent in debt obligations that
are in the lowest rating categories or are unrated, including debt obligations
of issuers not currently paying interest or who are in default. Investments in
debt obligations that are at risk of or in default present special tax issues
for the Fund. Tax rules are not entirely clear about issues such as when the
Fund may cease to accrue interest, original issue discount or market discount,
when and to what extent deductions may be taken for bad debts or worthless
securities and how payments received on obligations in default should be
allocated between principal and income. These and other related issues will be
addressed by the Fund when, as and if it invests in such securities, in order to
seek to ensure that it distributes sufficient income to preserve its status as a
regulated investment company and does not become subject to U.S. federal income
or excise tax.

         If the Fund utilizes leverage through borrowing, asset coverage
limitations imposed by the 1940 Act as well as additional restrictions that may
be imposed by certain lenders on the payment of dividends






                                      S-33

or distributions potentially could limit or eliminate the Fund's ability to make
distributions on its Common Shares and/or Preferred Shares until the asset
coverage is restored. These limitations could prevent the Fund from distributing
at least 90% of its net income as is required under the Code and therefore might
jeopardize the Fund's qualification for the reduced rates of corporate tax
applicable to certain regulated investment companies and/or might subject the
Fund to the nondeductible 4% excise tax. Upon any failure to meet the asset
coverage requirements imposed by the 1940 Act, the Fund may, in its sole
discretion and to the extent permitted under the 1940 Act, purchase or redeem
Preferred Shares in order to maintain or restore the requisite asset coverage
and avoid the adverse consequences to the Fund and its shareholders of failing
to meet the distribution requirements. There can be no assurance, however, that
any such action would achieve these objectives. The Fund will endeavor to avoid
restrictions on its ability to distribute dividends.

         If the Fund invests in certain pay-in-kind securities, zero coupon
securities, deferred interest securities or, in general, any other securities
with original issue discount (or with market discount if the Fund elects to
include market discount in income currently), the Fund must accrue income on
such investments for each taxable year, which generally will be prior to the
receipt of the corresponding cash payments. However, the Fund must distribute,
at least annually, all or substantially all of its net income, including such
accrued income, to shareholders to avoid U.S. federal income and excise taxes.
Therefore, the Fund may have to dispose of its portfolio securities under
disadvantageous circumstances to generate cash, or may have to leverage itself
by borrowing the cash, to satisfy distribution requirements.

         At the time of an investor's purchase of the Preferred Shares, a
portion of the purchase price may be attributable to realized or unrealized
appreciation in the Fund's portfolio or undistributed taxable income of the
Fund. Consequently, subsequent distributions by the Fund with respect to these
shares from such appreciation or income may be taxable to such investor even if
the net asset value of the investor's shares is, as a result of the
distributions, reduced below the investor's cost for such shares and the
distributions economically represent a return of a portion of the investment.

         Under present law and based in part on the fact that there is no
express or implied agreement between or among a Broker-Dealer or any other
party, and the Fund or any owners of Preferred Shares, that the Broker-Dealer or
any other party will guarantee or otherwise arrange to ensure that an owner of
Preferred Shares will be able to sell his or her shares, it is anticipated that
the Preferred Shares will constitute stock of the Fund, and thus distributions
with respect to the Preferred Shares (other than capital gain distributions and
distributions in redemption of the Preferred Shares subject to section 302(b) of
the Code) will generally constitute dividends to the extent of the Fund's
current or accumulated earnings and profits, as calculated for U.S. federal
income tax purposes. The following discussion assumes such treatment will apply.
Distributions in excess of current and accumulated earnings and profits of the
Fund are treated first as return of capital to the extent of the shareholder's
basis in the Preferred Shares and, thereafter, as capital gain.

         The Fund's income will consist of net investment income and may also
consist of net capital gain. The character of the Fund's income will not affect
the amount of dividends to which the holders of the Preferred Shares are
entitled. Holders of the Preferred Shares are entitled to receive only the
amount of dividends as determined by periodic auctions. For U.S. federal income
tax purposes, however, the Internal Revenue Service currently requires that a
regulated investment company that has two or more classes of shares allocate to
each such class proportionate amounts of each type of its income (such as
ordinary income and net capital gain) for each tax year. Accordingly, the Fund
intends to designate distributions made with respect to the common shares and
the Preferred Shares as consisting of particular types of income (net capital
gain, and ordinary income), in accordance with each class's proportionate share
of the total dividends paid to both classes. Thus, each dividend paid with
respect to the Preferred Shares during a year will be designated as ordinary
income dividends and, if the Fund designates any dividend as a capital gains
dividend, capital gains in proportion to the Preferred Shares proportionate
share of the total dividends paid on the Preferred Shares during the year to the
total distributions paid on both the Preferred





                                      S-34


Shares and the Common Shares during the year. Each holder of the Preferred
Shares during the year will be notified of the allocation within 60 days after
the end of the year. The amount of the net capital gain realized by the Fund may
not be significant, and there is no assurance that any such income will be
realized by the Fund in any year. Distributions of the Fund's net investment
income are taxable to shareholders as ordinary income. Distributions of the
Fund's net capital gain, if any, are taxable to shareholders at rates applicable
to long-term capital gains, regardless of the length of time the Preferred
Shares have been held by holders. Distributions in excess of the Fund's earnings
and profits will first reduce a shareholder's adjusted tax basis in his or her
shares of Preferred Shares and, after the adjusted tax basis is reduced to zero,
will constitute capital gains to a holder of shares of Preferred Shares who
holds his or her shares of Preferred Shares as a capital asset.

         Although the Fund is required to distribute annually at least 90% of
its net investment income, the Fund is not required to distribute net capital
gain to the shareholders. The Fund may retain and reinvest such gains and pay
federal income taxes on such gains (the "net undistributed capital gain").
However, it is unclear whether a portion of the net undistributed capital gain
would have to be allocated to the Preferred Shares for U.S. federal income tax
purposes. Until and unless the Fund receives acceptable guidance from the
Internal Revenue Service as to the allocation of the net undistributed capital
gain between the Common Shares and the Preferred Shares, the Fund intends to
distribute its net capital gain for any year during which it has shares of
Preferred Shares outstanding. Such distribution will affect the tax character
but not the amount of dividends to which holders of shares of Preferred Shares
are entitled.

         Sales and other dispositions of the Preferred Shares are taxable events
for shareholders that are subject to tax. Shareholders should consult their own
tax advisors with reference to their individual circumstances to determine
whether any particular transaction in the Preferred Shares is properly treated
as a sale for tax purposes (as the following discussion assumes) and the tax
treatment of any gains or losses recognized in such transactions. Any loss
realized by a shareholder upon the sale or other disposition of shares with a
tax holding period of six months or less will be treated as a long-term capital
loss to the extent of any amounts treated as distributions of long-term capital
gain with respect to such shares. Losses on sales or other dispositions of
shares may be disallowed under "wash sale" rules in the event of other
investments in the Fund (including those made pursuant to reinvestment of
dividends) within a period of 61 days beginning 30 days before and ending 30
days after a sale or other disposition of shares. In such a case, the disallowed
portion of any loss generally would be included in the U.S. federal tax basis of
the shares acquired in the other investments in the Fund.

         The Fund may engage in various transactions utilizing options, futures
contracts, forward contracts, hedge instruments, straddles, and other similar
transactions. Such transactions may be subject to special provisions of the Code
that, among other things, affect the character of any income realized by the
Fund from such investments, accelerate recognition of income to the Fund, defer
Fund losses, and affect the determination of whether capital gain and loss is
characterized as long-term or short-term capital gain or loss. These rules could
therefore affect the character, amount and timing of distributions to
shareholders. These provisions may also require the Fund to mark-to-market
certain types of the positions in its portfolio (i.e., treat them as if they
were closed out), which may cause the Fund to recognize income without receiving
cash with which to make distributions in amounts necessary to satisfy the
distribution requirements for avoiding U.S. federal income and excise taxes. The
Fund will monitor its transactions, will make the appropriate tax elections, and
will make the appropriate entries in its books and records when it acquires an
option, futures contract, forward contract, hedge instrument or other similar
investment in order to mitigate the effect of these rules, prevent
disqualification of the Fund as a regulated investment company and minimize the
imposition of U.S. federal income and excise taxes.

         Certain distributions by the Fund to its corporate shareholders may
qualify for the corporate dividends-received deduction subject to certain
holding period requirements and limitations on debt






                                      S-35


financings under the Code, but only to the extent the Fund earned dividend
income from stock investments in U.S. domestic corporations and certain other
requirements are satisfied. The Fund is permitted to acquire stocks of U.S.
domestic corporations, and it is therefore possible that a small portion of the
Fund's distributions, from the dividends attributable to such stocks, may
qualify for the dividend-received deduction. Such qualifying portion, if any,
may affect a corporate shareholder's liability for alternative minimum tax
and/or result in basis reductions and other consequences in certain
circumstances.

         The Fund may invest in REITs that hold residual interests in real
estate mortgage investment conduits ("REMICs"). Under Treasury regulations a
portion of the Fund's income from a REIT that is attributable to the REIT's
residual interest in a REMIC (referred to in the Code as an "excess inclusion")
will be subject to U.S. federal income tax in all events. These regulations also
provide that excess inclusion income of a regulated investment company, such as
the Fund, will be allocated to shareholders of the regulated investment company
in proportion to the dividends received by such shareholders, with the same
consequences as if the shareholders held the related REMIC residual interest
directly. In general, excess inclusion income allocated to shareholders (i)
cannot be offset by net operating losses (subject to a limited exception for
certain thrift institutions), (ii) will constitute unrelated business taxable
income to entities (including a qualified pension plan, an individual retirement
account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax
on unrelated business income, thereby potentially requiring such an entity that
is allocated excess inclusion income, and otherwise might not be required to
file a tax return, to file a tax return and pay tax on such income, and (iii) in
the case of a foreign shareholder, will not qualify for any reduction in U.S.
federal withholding tax. In addition, if at any time during any taxable year a
"disqualified organization" (as defined in the Code) is a record holder of a
share in a regulated investment company, then the regulated investment company
will be subject to a tax equal to that portion of its excess inclusion income
for the taxable year that is allocable to the disqualified organization,
multiplied by the highest federal income tax rate imposed on corporations. The
Fund does not intend to invest in REITs in which a substantial portion of the
assets will consist of residual interests in REMICs.

         The Fund may be subject to withholding and other taxes imposed by
foreign countries, including taxes on interest, dividends and capital gains with
respect to its investments in those countries, which would, if imposed, reduce
the yield on or return from those investments. Tax treaties between certain
countries and the U.S. may reduce or eliminate such taxes in some cases. The
Fund does not expect to satisfy the requirements for passing through to its
shareholders their pro rata shares of qualified foreign taxes paid by the Fund,
with the result that shareholders will not include such taxes in their gross
incomes and will not be entitled to a tax deduction or credit for such taxes on
their own tax returns.

         Federal law requires that the Fund withhold, as "backup withholding,"
30% (for calendar years 2002 and 2003) of reportable payments, including
dividends, capital gain distributions and the proceeds of sales or other
dispositions of the Preferred Shares paid to shareholders who have not complied
with IRS regulations. In order to avoid this withholding requirement,
shareholders must certify on their Account Applications, or on a separate IRS
Form W-9, that the Social Security Number or other Taxpayer Identification
Number they provide is their correct number and that they are not currently
subject to backup withholding, or that they are exempt from backup withholding.
The Fund may nevertheless be required to withhold if it receives notice from the
IRS or a broker that the number provided is incorrect or backup withholding is
applicable as a result of previous underreporting of interest or dividend
income.

         The description of certain federal tax provisions above relates only to
U.S. federal income tax consequences for shareholders who are U.S. persons,
(i.e., U.S. citizens or residents or U.S. corporations, partnerships, Funds or
estates and who are subject to U.S. federal income tax). Investors other than
U.S. persons may be subject to different U.S. tax treatment, including a
non-resident alien U.S. federal withholding






                                      S-36



tax at the rate of 30% or at a lower treaty rate on amounts treated as ordinary
dividends from the Fund and, unless an effective IRS Form W-8BEN, or other
authorized withholding certificate is on file, to backup withholding at the rate
of 30% on certain other payments from the Fund. Shareholders should consult
their own tax advisors on these matters and on any specific question of U.S.
federal, state, local, foreign and other applicable tax laws.

         2. Dividends.

                  (a) The Holders of shares of each Series shall be entitled to

                  of such Dividend Period; provided, however, if the Dividend
                  Period is more than 91 days then on the 91st, 181st and 271st
                  days within such period, if applicable, and on the Business
                  Day following the last day of such Dividend Period; and

                                    (B) with respect to any Dividend Period of
                  more than one year, on a quarterly basis on each January 1,
                  April 1, July 1 and October 1 within such Dividend Period and
                  on the Business Day following the last day of such Dividend

         such day for payment of dividends.

                           (iii) The Trust shall pay to the Paying Agent not
         later than 12:00 noon, New York City time, on each Dividend Payment
         Date for a Series, an aggregate amount of immediately available funds
         equal to the dividends to be paid to all Holders of such Series on




                                      A-2



         such Dividend Payment Date. The Trust shall not be required to
         establish any reserves for the payment of dividends.

                           (iv) All moneys paid to the Paying Agent for the
         payment of dividends shall be held in trust for the payment of such
         dividends by the Paying Agent for the benefit of the Holders specified
         in subparagraph (b)(v) of this Section 2. Any moneys paid to the Paying
         Agent in accordance with the foregoing but not applied by the Paying
         Agent to the payment of dividends will, upon request and to the extent
         permitted by law, be repaid to the Trust at the end of 90 days from the
         date on which such moneys were to have been so applied.

                           (v) Each dividend on each Series shall be paid on the
         Dividend Payment Date therefor to the Holders of that Series as their
         names appear on the share ledger or share records of the Trust on the
         Business Day next preceding such Dividend Payment Date; provided,
         however, if dividends are in arrears, they may be declared and paid at
         any time to Holders as their names appear on the share ledger or share
         records of the Trust on such date not exceeding 15 days preceding the
         payment date thereof, as may be fixed by the Board of Trustees. No
         interest will be payable in respect of any dividend payment or payments
         which may be in arrears.

                  (c) (i) The dividend rate on Outstanding shares of each Series
during the period from and after the Date of Original Issue to and including the
last day of the initial Dividend Period therefor shall be equal to the rate as
determined in the manner set forth under "Designation" above. For each
subsequent Dividend Period for each Series, the dividend rate shall be equal to
the rate per annum that results from an Auction (but the rate set at the Auction
will not exceed the Maximum Rate); provided, however, that if an Auction for any
subsequent Dividend Period of a Series is not held for any reason or if
Sufficient Clearing Orders have not been made in an Auction (other than as a
result of all shares of any Series being the subject of Submitted Hold Orders
and other than in an auction for a Special Dividend Period), then the dividend
rate on the shares of that Series For any such Dividend Period shall be the
Maximum Rate (except (i) during a Default Period when the dividend rate shall be
the Default Rate, as set forth in Section 2(c)(ii) below or (ii) after a Default
Period and prior to the beginning of the next Dividend Period when the dividend
rate shall be the Maximum Rate at the close of business on the last day of such
Default Period). If the Fund has declared a Special Dividend Period and there
are not Sufficient Clearing Orders, the dividend rate for the next rate period
will be the same as during the current rate period. If as a result of an
unforeseeable disruption of the financial markets, an Auction cannot be held for
a period of more than three business days, the dividend rate for the Subsequent
Dividend Period will be the same as the dividend rate for the current Dividend
Period.

                           (ii) Subject to the cure provisions in Section
         2(c)(iii) below, a "Default Period" with respect to a particular Series
         will commence on any date the Trust fails to deposit irrevocably in
         trust in same-day funds, with the Paying Agent by 12:00 noon, New York
         City time, (A) the full amount of any declared dividend on that Series
         payable on the Dividend Payment Date (a "Dividend Default") or (B) the
         full amount of any redemption price (the "Redemption Price") payable on
         the date fixed for redemption (the "Redemption Date") (a "Redemption
         Default") and together with a Dividend Default, hereinafter referred to
         as "Default").

         Subject to the cure provisions of Section 2(c)(iii) below, a Default
Period with respect to a Dividend Default or a Redemption Default shall end on
the Business Day on which, by 12:00 noon, New York City time, all unpaid
dividends and any unpaid Redemption Price shall have been deposited irrevocably
in trust in same-day funds with the Paying Agent. In the case of a Dividend
Default, the Applicable Rate for each Dividend Period commencing during a
Default Period will be equal to the Default Rate, and each subsequent Dividend
Period commencing after the beginning of a Default Period



                                      A-3




shall be a Standard Dividend Period; provided, however, that the commencement of
a Default Period will not by itself cause the commencement of a new Dividend
Period. No Auction shall be held during a Default Period applicable to that
Series.

                           (iii) No Default Period with respect to a Dividend
         Default or Redemption Default shall be deemed to commence if the amount
         of any dividend or any Redemption Price due (if such default is not
         solely due to the willful failure of the Trust) is deposited
         irrevocably in trust, in same-day funds with the Paying Agent by 12:00
         noon, New York City time within three Business Days after the
         applicable Dividend Payment Date or Redemption Date, together with an
         amount equal to the Default Rate applied to the amount of such
         non-payment based on the actual number of days comprising such period
         divided by 360 for each Series. The Default Rate shall be equal to the
         Reference Rate multiplied by three (3).

                           (iv) The amount of dividends per share payable (if
         declared) on each Dividend Payment Date of each Dividend Period of less
         than one (1) year (or in respect of dividends on another date in
         connection with a redemption during such Dividend Period) shall be
         computed by multiplying the Applicable Rate (or the Default Rate) for
         such Dividend Period (or a portion thereof) by a fraction, the
         numerator of which will be the number of days in such Dividend Period
         (or portion thereof) that such share was Outstanding and for which the
         Applicable Rate or the Default Rate was applicable and the denominator
         of which will be 360 for each Series, multiplying the amount so
         obtained by $25,000, and rounding the amount so obtained to the nearest
         cent. During any Dividend Period of one (1) year or more, the amount of
         dividends per share payable on any Dividend Payment Date (or in respect
         of dividends on another date in connection with a redemption during
         such Dividend Period) shall be computed as described in the preceding
         sentence, except that it will be determined on the basis of a year
         consisting of twelve 30-day months.

                  (d) Any dividend payment made on shares of any Series shall
first be credited against the earliest accumulated but unpaid dividends due with
respect to that Series.

                  (e) For so long as the Preferred Shares are Outstanding,
except as otherwise contemplated by Part I of this Statement, the Trust will not
declare, pay or set apart for payment any dividend or other distribution (other
than a dividend or distribution paid in shares of, or options, warrants or
rights to subscribe for or purchase, Common Shares or other shares ranking
junior to the Preferred Shares as to dividends or upon liquidation) with respect
to Common Shares or any other shares of beneficial interest of the Trust ranking
junior to the Preferred Shares as to dividends or upon liquidation, or call for
redemption, redeem, purchase or otherwise acquire for consideration any Common
Shares or other shares of beneficial interest ranking junior to the Preferred
Shares (except by conversion into or exchange for shares of the Trust ranking
junior to the Preferred Shares as to dividends and upon liquidation), unless (i)
immediately after such transaction, the Trust would have Eligible Assets with an
aggregate Discounted Value at least equal to the Preferred Shares Basic
Maintenance Amount and the 1940 Act Preferred Shares Asset Coverage would be
achieved, (ii) all cumulative and unpaid dividends due on or prior to the date
of the transaction have been declared and paid in full with respect to the
Trust's preferred shares, including the Preferred Shares or shall have been
declared and sufficient funds for the payment thereof deposited with the Auction
Agent, and (iii) the Trust has redeemed the full number of shares of preferred
required to be redeemed by any mandatory provision for redemption including the
Preferred Shares required to be redeemed by any provision for mandatory
redemption contained in Section 3(a)(ii) of Part I of this Supplement.

                  (f) For so long as the Preferred Shares are Outstanding,
except as set forth in the next sentence, the Trust will not declare, pay or set
apart for payment on any Series of shares of beneficial







                                      A-4


interest of the Trust ranking, as to the payment of dividends, on a parity with
the Preferred Shares for any period unless full cumulative dividends have been
or contemporaneously are declared and paid on each Series through their most
recent Dividend Payment Date. When dividends are not paid in full upon the
Preferred Shares through their most recent Dividend Payment Dates or upon any
other Series of shares of beneficial interest ranking on a parity as to the
payment of dividends with Preferred Shares through their most recent respective
Dividend Payment Dates, all dividends declared upon the Preferred Shares and any
other such Series of shares of beneficial interest ranking on a parity as to the
payment of dividends with the Preferred Shares shall be declared pro rata so
that the amount of dividends declared per share on the Preferred Shares and such
other Series of preferred shares of beneficial interest ranking on a parity
therewith shall in all cases bear to each other the same ratio that accumulated
dividends per share on the Preferred Shares and such other Series of preferred
shares of beneficial interest ranking on a parity therewith bear to each other.

         3. Redemption.

                  (a) (i) After the initial Dividend Period, subject to the
provisions of this Section 3 and to the extent permitted under the 1940 Act and
Delaware law, the Trust may, at its option, redeem in whole or in part out of
funds legally available therefor shares of any Series herein designated as (A)
having a Dividend Period of one year or less, on the Business Day after the last
day of such Dividend Period by delivering a notice of redemption not less than
15 calendar days and not more than 40 calendar days prior to the Redemption
Date, at a redemption price per share equal to $25,000, plus an amount equal to
accumulated but unpaid dividends thereon (whether or not earned or declared) to
the Redemption Date ("Redemption Price"), or (B) having a Dividend Period of
more than one year, on any Business Day prior to the end of the relevant
Dividend Period by delivering a notice of redemption not less than 15 calendar
days and not more than 40 calendar days prior to the Redemption Date, at the
Redemption Price, plus a redemption premium, if any, determined by the Board of
Trustees after consultation with the Broker-Dealers and set forth in any
applicable Specific Redemption Provisions at the time of the designation of such
Dividend Period as set forth in Section 4 of Part I of this Statement; provided,
however, that during a Dividend Period of more than one year, no shares of any
Series Will be subject to optional redemption except in accordance with any
Specific Redemption Provisions approved by the Board of Trustees after
consultation with the Broker-Dealers at the time of the designation of such
Dividend Period. Notwithstanding the foregoing, the Trust shall not give a
notice of or effect any redemption pursuant to this Section 3(a)(i) unless, on
the date on which the Trust gives such notice and on the Redemption Date, (a)
the Trust has available Deposit Securities with maturity or tender dates not
later than the day preceding the applicable Redemption Date and having a value
not less than the amount (including any applicable premium) due to Holders of
each Series by reason of the redemption of each Series on the Redemption Date
and (b) the Trust would have Eligible Assets with an aggregate Discounted Value
at least equal to the Preferred Shares Basic Maintenance Amount immediately
subsequent to such redemption, if such redemption were to occur on such date, it
being understood that the provisions of paragraph (d) of this Section 3 shall be
applicable in such circumstances in the event the Trust makes the deposit and
takes the other action required thereby.

                           (ii) If the Trust fails as of any Valuation Date to
         meet the Preferred Shares Basic Maintenance Amount Test or, as of the
         last Business Day of any month, the 1940 Act Preferred Shares Asset
         Coverage, and such failure is not cured within ten Business Days
         following the relevant Valuation Date, in the case of a failure to meet
         the Preferred Shares Basic Maintenance Amount Test, or the last
         Business Day of the following month in the case of a failure to meet
         the 1940 Act Preferred Shares Asset Coverage (each an "Asset Coverage
         Cure Date"), the Preferred Shares will be subject to mandatory
         redemption out of funds legally available therefor. The number of
         Preferred Shares to be redeemed in such circumstances will be equal to
         the lesser of (A) the minimum number of Preferred Shares the redemption
         of which, if




                                      A-5


         deemed to have occurred immediately prior to the opening of business on
         the relevant Asset Coverage Cure Date, would result in the Trust
         meeting the Preferred Shares Basic Maintenance Amount Test, and the
         1940 Act Preferred Shares Asset Coverage, as the case may be, in either
         case as of the relevant Asset Coverage Cure Date (provided that, if
         there is no such minimum number of shares the redemption of which would
         have such result, all Preferred Shares then Outstanding will be
         redeemed) and (B) the maximum number of Preferred Shares that can be
         redeemed out of funds expected to be available therefor on the
         Mandatory Redemption Date at the Mandatory Redemption Price set forth
         in subparagraph (a)(iii) of this Section 3.

                           (iii) In determining the Preferred Shares required to
         be redeemed in accordance with the foregoing Section 3(a)(ii), the
         Trust shall allocate the number of shares required to be redeemed to
         satisfy the Preferred Shares Basic Maintenance Amount Test or the 1940
         Act Preferred Shares Asset Coverage, as the case may be, pro rata or
         among the Holders of the Preferred Shares in proportion to the number
         of shares they hold and other preferred shares subject to mandatory
         redemption provisions similar to those contained in this Section 3,
         subject to the further provisions of this subparagraph (iii). The Trust
         shall effect any required mandatory redemption pursuant to: (A) the
         Preferred Shares Basic Maintenance Amount Test, as described in
         subparagraph (a)(ii) of this Section 3, no later than 30 days after the
         Trust last met the Preferred Shares Basic Maintenance Amount Test, or
         (B) the 1940 Act Preferred Shares Asset Coverage, as described in
         subparagraph (a)(ii) of this Section 3, no later than 30 days after the
         Asset Coverage Cure Date (the "Mandatory Redemption Date"), except that
         if the Trust does not have funds legally available for the redemption
         of, or is not otherwise legally permitted to redeem, the number of
         Preferred Shares which would be required to be redeemed by the Trust
         under clause (A) of subparagraph (a)(ii) of this Section 3 if
         sufficient funds were available, together with other preferred shares
         which are subject to mandatory redemption under provisions similar to
         those contained in this Section 3, or the Trust otherwise is unable to
         effect such redemption on or prior to such Mandatory Redemption Date,
         the Trust shall redeem those Preferred Shares, and other preferred
         shares which it was unable to redeem, on the earliest practicable date
         on which the Trust will have such funds available, upon notice pursuant
         to Section 3(b) to record owners of Preferred Shares to be redeemed and
         the Paying Agent. The Trust will deposit with the Paying Agent funds
         sufficient to redeem the specified number of Preferred Shares with
         respect to a redemption required under subparagraph (a)(ii) of this
         Section 3, by 1:00 P.M., New York City time, of the Business Day
         immediately preceding the Mandatory Redemption Date. If fewer than all
         of the Outstanding Preferred Shares are to be redeemed pursuant to this
         Section 3(a)(iii), the number of shares to be redeemed shall be
         redeemed pro rata from the Holders of such shares in proportion to the
         number of the Preferred Shares held by such Holders, by lot or by such
         other method as the Trust shall deem fair and equitable, subject,
         however, to the terms of any applicable Specific Redemption Provisions.
         "Mandatory Redemption Price" means the Redemption Price plus (in the
         case of a Dividend Period of one year or more only) a redemption
         premium, if any, determined by the Board of Trustees after consultation
         with the Broker-Dealers and set forth in any applicable Specific
         Redemption Provisions.

                  (b) In the event of a redemption pursuant to the foregoing
Section 3(a), the Trust will file a notice of its intention to redeem with the
Securities and Exchange Commission so as to provide at least the minimum notice
required under Rule 23c-2 under the 1940 Act or any successor provision. In
addition, the Trust shall deliver a notice of redemption to the Auction Agent
(the "Notice of Redemption") containing the information set forth below (i) in
the case of an optional redemption pursuant to Section 3(a)(i) above, one
Business Day prior to the giving of notice to the Holders, (ii) in the case of a
mandatory redemption pursuant to Section 3(a)(ii) above, on or prior to the 10th
day preceding the Mandatory Redemption Date. Only with respect to shares held by
the Securities Depository, the





                                      A-6



Auction Agent will use its reasonable efforts to provide telephonic notice to
each Holder of shares of any Series called for redemption not later than the
close of business on the Business Day immediately following the day on which the
Auction Agent determines the shares to be redeemed (or, during a Default Period
with respect to such shares, not later than the close of business on the
Business Day immediately following the day on which the Auction Agent receives
Notice of Redemption from the Trust). The Auction Agent shall confirm such
telephonic notice in writing not later than the close of business on the third
Business Day preceding the date fixed for redemption by providing the Notice of
Redemption to each Holder of shares called for redemption, the Paying Agent (if
different from the Auction Agent) and the Securities Depository. Notice of
Redemption will be addressed to the registered owners of shares of any Series at
their addresses appearing on the share records of the Trust. Such Notice of
Redemption will set forth (i) the date fixed for redemption, (ii) the number and
identity of shares of each Series To be redeemed, (iii) the redemption price
(specifying the amount of accumulated dividends to be included therein), (iv)
that dividends on the shares to be redeemed will cease to accumulate on such
date fixed for redemption, and (v) the provision under which redemption shall be
made. No defect in the Notice of Redemption or in the transmittal or mailing
thereof will affect the validity of the redemption proceedings, except as
required by applicable law. If fewer than all shares held by any Holder are to
be redeemed, the Notice of Redemption mailed to such Holder shall also specify
the number of shares to be redeemed from such Holder.

                  (c) Notwithstanding the provisions of paragraph (a) of this
Section 3, no preferred shares, including the Preferred Shares, may be redeemed
at the option of the Trust unless all dividends in arrears on the Outstanding
Preferred Shares and any other preferred shares have been or are being
contemporaneously paid or set aside for payment; provided, however, that the
foregoing shall not prevent the purchase or acquisition of outstanding preferred
shares pursuant to the successful completion of an otherwise lawful purchase or
exchange offer made on the same terms to holders of all outstanding preferred
shares.

                  (d) Upon the deposit of funds sufficient to redeem shares of
any Series with the Paying Agent and the giving of the Notice of Redemption to
the Auction Agent under paragraph (b) of this Section 3, dividends on such
shares shall cease to accumulate and such shares shall no longer be deemed to be
Outstanding for any purpose (including, without limitation, for purposes of
calculating whether the Trust has met the Preferred Shares Basic Maintenance
Amount Test or the 1940 Act Preferred Shares Asset Coverage), and all rights of
the Holders of the shares so called for redemption shall cease and terminate,
except the right of such Holder to receive the redemption price specified
herein, but without any interest or other additional amount. Such redemption
price shall be paid by the Paying Agent to the nominee of the Securities
Depository. The Trust shall be entitled to receive from the Paying Agent,
promptly after the date fixed for redemption, any cash deposited with the Paying
Agent in excess of (i) the aggregate redemption price of the shares of any
Series called for redemption on such date and (ii) such other amounts, if any,
to which Holders of shares of any Series called for redemption may be entitled.
Any funds so deposited that are unclaimed at the end of two years from such
redemption date shall, to the extent permitted by law, be paid to the Trust,
after which time the Holders of shares of each Series so called for redemption
may look only to the Trust for payment of the redemption price and all other
amounts, if any, to which they may be entitled; provided, however, that the
Paying Agent shall notify all Holders whose funds are unclaimed by placing a
notice in The Wall Street Journal concerning the availability of such funds once
each week for three consecutive weeks. The Trust shall be entitled to receive,
from time to time after the date fixed for redemption, any interest earned on
the funds so deposited.

                  (e) To the extent that any redemption for which Notice of
Redemption has been given is not made by reason of the absence of legally
available funds therefor, or is otherwise prohibited, such redemption shall be
made as soon as practicable to the extent such funds become legally available or






                                      A-7


such redemption is no longer otherwise prohibited. Failure to redeem shares of
any Series shall be deemed to exist at any time after the date specified for
redemption in a Notice of Redemption when the Trust shall have failed, for any
reason whatsoever, to deposit in trust with the Paying Agent the redemption
price with respect to any shares for which such Notice of Redemption has been
given. Notwithstanding the fact that the Trust may not have redeemed shares of
each Series for which a Notice of Redemption has been given, dividends may be
declared and paid on shares of any Series and shall include those shares of any
Series for which Notice of Redemption has been given but for which deposit of
funds has not been made.

                  (f) All moneys paid to the Paying Agent for payment of the
redemption price of shares of any Series called for redemption shall be held in
trust by the Paying Agent for the benefit of holders of shares so to be
redeemed.

                  (g) So long as any shares of any Series are held of record by
the nominee of the Securities Depository, the redemption price for such shares
will be paid on the date fixed for redemption to the nominee of the Securities
Depository for distribution to Agent Members for distribution to the persons for
whom they are acting as agent.

                  (h) Except for the provisions described above, nothing
contained in this Statement limits any right of the Trust to purchase or
otherwise acquire any shares of each Series outside of an Auction at any price,
whether higher or lower than the price that would be paid in connection with an
optional or mandatory redemption, so long as, at the time of any such purchase,
there is no arrearage in the payment of dividends on, or the mandatory or
optional redemption price with respect to, any shares of each Series For which
Notice of Redemption has been given and the Trust meets the 1940 Act Preferred
Shares Asset Coverage and the Preferred Shares Basic Maintenance Amount Test
after giving effect to such purchase or acquisition on the date thereof. Any
shares which are purchased, redeemed or otherwise acquired by the Trust shall
have no voting rights. If fewer than all the Outstanding shares of any Series
are redeemed or otherwise acquired by the Trust, the Trust shall give notice of
such transaction to the auction agent, in accordance with the procedures agreed
upon by the Board of Trustees.

                  (i) In the case of any redemption pursuant to this Section 3,
only whole shares of each Series shall be redeemed, and in the event that any
provision of the Charter would require redemption of a fractional share, the
Auction Agent shall be authorized to round up so that only whole shares are
redeemed.

                  (j) Notwithstanding anything herein to the contrary,
including, without limitation, Section 6(k) of Part I of this Statement, the
Board of Trustees, upon notification to each Rating Agency, may authorize,
create or issue other Series of preferred shares, including other Series of
Preferred Shares, Series of preferred shares ranking on a parity with the
Preferred Shares with respect to the payment of dividends or the distribution of
assets upon dissolution, liquidation or winding up of the affairs of the Trust,
to the extent permitted by the 1940 Act, if upon issuance of any such series,
either (A) the net proceeds from the sale of such shares (or such portion
thereof needed to redeem or repurchase the Outstanding Preferred Shares) are
deposited with the Paying Agent in accordance with Section 3(d) of Part I of
this Statement, Notice of Redemption as contemplated by Section 3(b) of Part I
of these Articles Supplementary has been delivered prior thereto or is sent
promptly thereafter, and such proceeds are used to redeem all Outstanding
Preferred Shares or (B) the Trust would meet the 1940 Act Preferred Shares Asset
Coverage, the Preferred Shares Basic Maintenance Amount Test and the
requirements of Section 12(b) of Part I of this Statement.


                                      A-8



         4. Designation of Dividend Period.

                  (a) The initial Dividend Period for each Series shall be as
determined in the manner set forth under "Designation" above. The Trust will
designate the duration of subsequent Dividend Periods of each Series; provided,
however, that no such designation is necessary for a Standard Dividend Period
and, provided further, that any designation of a Special Dividend Period shall
be effective only if (i) notice thereof shall have been given as provided
herein, (ii) any failure to pay in a timely manner to the Auction Agent the full
amount of any dividend on, or the redemption price of, each Series shall have
been cured as provided above, (iii) Sufficient Clearing Orders shall have
existed in an Auction held on the Auction Date immediately preceding the first
day of such proposed Special Dividend Period, (iv) if the Trust shall have
mailed a Notice of Redemption with respect to any shares, the redemption price
with respect to such shares shall have been deposited with the Paying Agent, (v)
in the case of the designation of a Special Dividend Period, the Broker-Dealers
shall have notified the Trust in writing that it believes the Auction for the
Special Dividend Period will be successful, and (vi) each Rating Agency shall
have confirmed in writing to the Trust that such designation shall not adversely
affect their respective then-current ratings of the Preferred Shares.

                  (b) If the Trust proposes to designate any Special Dividend
Period, not fewer than seven Business Days (or two Business Days in the event
the duration of the Dividend Period prior to such Special Dividend Period is
fewer than eight days) nor more than 30 Business Days prior to the first day of
such Special Dividend Period, notice shall be (i) made by press release and (ii)
communicated by the Trust by telephonic or other means to the Auction Agent and
each Broker-Dealer and confirmed in writing promptly thereafter. Each such
notice shall state (A) that the Trust proposes to exercise its option to
designate a succeeding Special Dividend Period, specifying the first and last
days thereof and the Maximum Applicable Rate for such Special Dividend Period
and (B) that the Trust will by 3:00 P.M., New York City time, on the second
Business Day next preceding the first day of such Special Dividend Period,
notify the Auction Agent, who will promptly notify the Broker-Dealers, of either
(x) its determination, subject to certain conditions, to proceed with such
Special Dividend Period, subject to the terms of any Specific Redemption
Provisions, or (y) its determination not to proceed with such Special Dividend
Period, in which latter event the succeeding Dividend Period shall be a Standard
Dividend Period. No later than 3:00 P.M., New York City time, on the second
Business Day next preceding the first day of any proposed Special Dividend
Period, the Trust shall deliver to the Auction Agent, who will promptly deliver
to the Broker-Dealers and Existing Holders, either:

                           (i) a notice stating (A) that the Trust has
         determined to designate the next succeeding Dividend Period as a
         Special Dividend Period, specifying the first and last days thereof and
         (B) the terms of any Specific Redemption Provisions; or

                           (ii) a notice stating that the Trust has determined
         not to exercise its option to designate a Special Dividend Period.

         If the Trust fails to deliver either such notice with respect to any
designation of any proposed Special Dividend Period to the Auction Agent or is
unable to make the confirmation provided in clause (v) of paragraph (a) of this
Section 4 by 3:00 P.M., New York City time, on the second Business Day next
preceding the first day of such proposed Special Dividend Period, the Trust
shall be deemed to have delivered a notice to the Auction Agent with respect to
such Dividend Period to the effect set forth in clause (ii) above, thereby
resulting in a Standard Dividend Period.

         5. Restrictions on Transfer. Shares of each Series may be transferred
only (a) pursuant to an order placed in an Auction, (b) to or through a
Broker-Dealer or (c) to the Trust or any Affiliate. Notwithstanding the
foregoing, a transfer other than pursuant to an Auction will not be effective
unless




                                      A-9


the selling Existing Holder or the Agent Member of such Existing Holder, in the
case of an Existing Holder whose shares are listed in its own name on the books
of the Auction Agent, or the Broker-Dealer or Agent Member of such
Broker-Dealer, in the case of a transfer between persons holding shares of any
Series through different Broker-Dealers, advises the Auction Agent of such
transfer. The certificates representing the shares of each Series issued to the
Securities Depository will bear legends with respect to the restrictions
described above and stop-transfer instructions will be issued to the Transfer
Agent and/or Registrar.

         6. Voting Rights.

                  (a) Except as otherwise provided in the Declaration or as
otherwise required by applicable law, (i) each Holder of shares of any Series
shall be entitled to one vote for each share of any Series held on each matter
on which the Holders of the Preferred Shares are entitled to vote, and (ii) the
holders of the Outstanding preferred shares, including each Series, and holders
of shares of Common Shares shall vote together as a single class on all matters
submitted to the shareholders; provided, however, that, with respect to the
election of trustees, the holders of the Outstanding preferred shares, including
each Series, represented in person or by proxy at a meeting for the election of
trustees, shall be entitled, as a class, to the exclusion of the holders of all
other securities and classes of shares, including the Common Shares, to elect
two trustees of the Trust, each share of preferred, including each Series,
entitling the holder thereof to one vote. The identities of the nominees of such
trusteeships may be fixed by the Board of Trustees. Subject to paragraph (b) of
this Section 6, the holders of outstanding shares of Common Shares and
outstanding preferred shares, including each Series, voting together as a single
class, shall be entitled to elect the balance of the trustees.

                  (b) If at any time dividends on the Preferred Shares shall be
unpaid in an amount equal to two full years" dividends on the Preferred Shares
(a "Voting Period"), the number of trustees constituting the Board of Trustees
shall be automatically increased by the smallest number of additional trustees
that, when added to the number of trustees then constituting the Board of
Trustees, shall (together with the two trustees elected by the holders of
preferred shares, including each Series, pursuant to paragraph (a) of this
Section 6) constitute a majority of such increased number, and the holders of
any shares of preferred shares, including each Series, shall be entitled, voting
as a single class on a one-vote-per-share basis (to the exclusion of the holders
of all other securities and classes of shares of the Trust), to elect the
smallest number of such additional trustees of the Trust that shall constitute a
majority of the total number of trustees of the Trust so increased. The Voting
Period and the voting rights so created upon the occurrence of the conditions
set forth in this paragraph (b) of Section 6 shall continue unless and until all
dividends in arrears on each Series shall have been paid or declared and
sufficient cash or specified securities are set apart for the payment of such
dividends. Upon the termination of a Voting Period, the voting rights described
in this paragraph (b) of Section 6 shall cease, subject always, however, to the
revesting of such voting rights in the holders of preferred shares, including
each Series, upon the further occurrence of any of the events described in this
paragraph (b) of Section 6.

                  (c) As soon as practicable after the accrual of any right of
the holders of preferred shares, including each Series, to elect additional
trustees as described in paragraph (b) of this Section 6, the Trust shall notify
the Auction Agent, and the Auction Agent shall call a special meeting of such
holders, by mailing a notice of such special meeting to such holders, such
meeting to be held not less than ten nor more than 90 days after the date of
mailing of such notice. If the Trust fails to send such notice to the Auction
Agent or if the Auction Agent does not call such a special meeting, it may be
called by any such holder on like notice. The record date for determining the
holders entitled to notice of and to vote at such special meeting shall be the
close of business on the fifth Business Day preceding the day on which such
notice is mailed. At any such special meeting and at each meeting of holders of
preferred shares, including each Series, held during a Voting Period at which
trustees are to be elected, such holders, voting





                                      A-10


together as a class (to the exclusion of the holders of all other securities and
classes of shares of the Trust), shall be entitled to elect the number of
trustees prescribed in paragraph (b) of this Section 6 on a one-vote-per-share
basis. At any such meeting or adjournment thereof in the absence of a quorum, a
majority of the holders of preferred shares, including Holders of the Preferred
Shares, present in person or by proxy shall have the power to adjourn the
meeting without notice, other than an announcement at the meeting, until a
quorum is present.

                  (d) For purposes of determining any rights of the holders of
the shares of preferred shares, including each Series, to vote on any matter,
whether such right is created by this Statement, by statute or otherwise, if
redemption of some or all of the preferred shares, including each Series, is
required, no holder of preferred shares, including each Series, shall be
entitled to vote and no preferred shares, including each Series, shall be deemed
to be "outstanding" for the purpose of voting or determining the number of
shares required to constitute a quorum, if prior to or concurrently with the
time of determination, sufficient Deposit Securities for the redemption of such
shares have been deposited in the case of Preferred Shares in trust with the
Paying Agent for that purpose and the requisite Notice of Redemption with
respect to such shares shall have been given as provided in Section 3(b) of Part
I of this Statement and in the case of other preferred shares the Trust has
otherwise met the conditions for redemption applicable to such shares.

                  (e) The terms of office of all persons who are trustees of the
Trust at the time of a special meeting of Holders of the Preferred Shares and
holders of other preferred shares to elect trustees pursuant to paragraph (b) of
this Section 6 shall continue, notwithstanding the election at such meeting by
the holders of the number of trustees that they are entitled to elect.

                  (f) Simultaneously with the termination of a Voting Period,
the terms of office of the additional trustees elected by the Holders of the
Preferred Shares and holders of other preferred shares pursuant to paragraph (b)
of this Section 6 shall terminate, the remaining trustees shall constitute the
trustees of the Trust and the voting rights of such holders to elect additional
trustees pursuant to paragraph (b) of this Section 6 shall cease, subject to the
provisions of the last sentence of paragraph (b) of this Section 6.

                  (g) Unless otherwise required by law or in the Trust's
Declaration, the Holders of Preferred Shares shall not have any relative rights
or preferences or other special rights other than those specifically set forth
herein. In the event that the Trust fails to pay any dividends on the Preferred
Shares of the Trust or fails to redeem any Preferred Shares which it is required
to redeem, or any other event occurs which requires the mandatory redemption of
Preferred Shares and the required Notice of Redemption has not been given, other
than the rights set forth in paragraph (a) of Section 3 of Part I of this
Statement, the exclusive remedy of the Holders of Preferred Shares shall be the
right to vote for trustees pursuant to the provisions of paragraph (b) of this
Section 6. In no event shall the Holders of Preferred Shares have any right to
sue for, or bring a proceeding with respect to, such dividends or redemptions or
damages for the failure to receive the same.

                  (h) For so long as any preferred shares, including each
Series, are outstanding, the Trust will not, without the affirmative vote of the
Holders of a majority of the outstanding preferred shares, (i) institute any
proceedings to be adjudicated bankrupt or insolvent, or consent to the
institution of bankruptcy or insolvency proceedings against it, or file a
petition seeking or consenting to reorganization or relief under any applicable
federal or state law relating to bankruptcy or insolvency, or consent to the
appointment of a receiver, liquidator, assignee, trustee, sequestrator (or other
similar official) of the Trust or a substantial part of its property, or make
any assignment for the benefit of creditors, or, except as may be required by
applicable law, admit in writing its inability to pay its debts generally as
they become due or take any corporate action in furtherance of any such action;
(ii) create,






                                      A-11


incur or suffer to exist, or agree to create, incur or suffer to exist, or
consent to cause or permit in the future (upon the happening of a contingency or
otherwise) the creation, incurrence or existence of any material lien, mortgage,
pledge, charge, security interest, security agreement, conditional sale or trust
receipt or other material encumbrance of any kind upon any of the Trust's assets
as a whole, except (A) liens the validity of which are being contested in good
faith by appropriate proceedings, (B) liens for taxes that are not then due and
payable or that can be paid thereafter without penalty, (C) liens, pledges,
charges, security interests, security agreements or other encumbrances arising
in connection with any indebtedness senior to the Preferred Shares, (D) liens,
pledges, charges, security interests, security agreements or other encumbrances
arising in connection with any indebtedness permitted under clause (iii) below
and (E) liens to secure payment for services rendered including, without
limitation, services rendered by the Trust's Paying Agent and the Auction Agent;
or (iii) create, authorize, issue, incur or suffer to exist any indebtedness for
borrowed money or any direct or indirect guarantee of such indebtedness for
borrowed money or any direct or indirect guarantee of such indebtedness, except
the Trust may borrow as may be permitted by the Trust's investment restrictions;
provided, however, that transfers of assets by the Trust subject to an
obligation to repurchase shall not be deemed to be indebtedness for purposes of
this provision to the extent that after any such transaction the Trust has
Eligible Assets with an aggregate Discounted Value at least equal to the
Preferred Shares Basic Maintenance Amount as of the immediately preceding
Valuation Date.

                  (i) The affirmative vote of the holders of a majority, as
defined in the 1940 Act, of the outstanding preferred shares, including each
Series, voting as a separate class, shall be required to approve any plan of
reorganization (as such term is used in the 1940 Act) adversely affecting such
shares or any action requiring a vote of security holders of the Trust under
Section 13(a) of the 1940 Act. In the event a vote of holders of preferred
shares is required pursuant to the provisions of Section 13(a) of the 1940 Act,
the Trust shall, not later than ten Business Days prior to the date on which
such vote is to be taken, notify each Rating Agency that such vote is to be
taken and the nature of the action with respect to which such vote is to be
taken and shall, not later than ten Business Days after the date on which such
vote is taken, notify each Rating Agency of the results of such vote.

                  (j) The affirmative vote of the Holders of a majority, as
defined in the 1940 Act, of the outstanding preferred shares of any series,
voting separately from any other series, shall be required with respect to any
matter that materially and adversely affects the rights, preferences, or powers
of that Series in a manner different from that of other Series or classes of the
Trust's shares of beneficial interest. For purposes of the foregoing, no matter
shall be deemed to adversely affect any rights, preference or power unless such
matter (i) alters or abolishes any preferential right of such series; (ii)
creates, alters or abolishes any right in respect of redemption of such series;
or (iii) creates or alters (other than to abolish) any restriction on transfer
applicable to such series. The vote of holders of any Series described in this
Section (j) will in each case be in addition to a separate vote of the requisite
percentage of Common Shares and/or preferred shares necessary to authorize the
action in question.

                  (k) The Board of Trustees, without the vote or consent of any
holder of preferred shares, including each Series, or any other shareholder of
the Trust, may from time to time amend, alter or repeal any or all of the
definitions contained herein, add covenants and other obligations of the Trust,
or confirm the applicability of covenants and other obligations set forth
herein, all in connection with obtaining or maintaining the rating of any Rating
Agency with respect to each Series, and any such amendment, alteration or repeal
will not be deemed to affect the preferences, rights or powers of Preferred
Shares or the Holders thereof, provided that the Board of Trustees receives
written confirmation from each relevant Rating Agency (with such confirmation in
no event being required to be obtained from a particular Rating Agency with
respect to definitions or other provisions relevant only to and adopted in
connection with another Rating Agency's rating of the any Series) that any such
amendment, alteration or repeal would not adversely affect the rating then
assigned by such Rating Agency.





                                      A-12


         In addition, subject to compliance with applicable law, the Board of
Trustees may amend the definition of Maximum Rate to increase the percentage
amount by which the Reference Rate is multiplied to determine the Maximum Rate
shown therein without the vote or consent of the holders of shares of preferred,
including each Series, or any other shareholder of the Trust, but only with
confirmation from each Rating Agency, and after consultation with the
Broker-Dealers, provided that immediately following any such increase the Trust
would meet the Preferred Shares Basic Maintenance Amount Test.

         7. Liquidation Rights.

                  (a) In the event of any liquidation, dissolution or winding up
of the affairs of the Trust, whether voluntary or involuntary, the holders of
preferred shares, including each Series, shall be entitled to receive out of the
assets of the Trust available for distribution to shareholders, after claims of
creditors but before distribution or payment shall be made in respect of the
Common Shares or to any other shares of beneficial interest of the Trust ranking
junior to the preferred shares, as to liquidation payments, a liquidation
distribution in the amount of $25,000 per share (the "Liquidation Preference"),
plus an amount equal to all unpaid dividends accrued to and including the date
fixed for such distribution or payment (whether or not declared by the Board of
Trustees, but excluding interest thereon), but such Holders shall be entitled to
no further participation in any distribution or payment in connection with any
such liquidation, dissolution or winding up. Each Series shall rank on a parity
with shares of any other Series of preferred shares of the Trust (including each
Series) as to the distribution of assets upon dissolution, liquidation or
winding up of the affairs of the Trust.

                  (b) If, upon any such liquidation, dissolution or winding up
of the affairs of the Trust, whether voluntary or involuntary, the assets of the
Trust available for distribution among the holders of all outstanding preferred
shares, including each Series, shall be insufficient to permit the payment in
full to such holders of the amounts to which they are entitled, then such
available assets shall be distributed among the holders of all outstanding
preferred shares, including each Series, ratably in any such distribution of
assets according to the respective amounts which would be payable on all such
shares if all amounts thereon were paid in full. Unless and until payment in
full has been made to the holders of all outstanding preferred shares, including
each Series, of the liquidation distributions to which they are entitled, no
dividends or distributions will be made to holders of Common Shares or any
shares of beneficial interest of the Trust ranking junior to the preferred
shares as to liquidation.

                  (c) Neither the consolidation nor merger of the Trust with or
into any other business entity, nor the sale, lease, exchange or transfer by the
Trust of all or substantially all of its property and assets, shall be deemed to
be a liquidation, dissolution or winding up of the Trust for purposes of this
Section 7.

                  (d) After the payment to Holders of Preferred Shares of the
full preferential amounts provided for in this Section 7, the Holders of the
Preferred Shares as such shall have no right or claim to any of the remaining
assets of the Trust.

                  (e) In the event the assets of the Trust or proceeds thereof
available for distribution to the Holders of Preferred Shares, upon dissolution,
liquidation or winding up of the affairs of the Trust, whether voluntary or
involuntary, shall be insufficient to pay in full all amounts to which such
Holders are entitled pursuant to paragraph (a) of this Section 7, no such
distribution shall be made on account of any shares of any other Series of
preferred shares unless proportionate distributive amounts shall be paid on
account of the Preferred Shares, ratably, in proportion to the full
distributable amounts to which holders of all preferred shares are entitled upon
such dissolution, liquidation or winding up.





                                      A-13


                  (f) Subject to the rights of the holders of other preferred
shares or after payment shall have been made in full to the Holders of Preferred
Shares as provided in paragraph (a) of this Section 7, but not prior thereto,
any other Series or class of shares ranking junior to the Preferred Shares with
respect to the distribution of assets upon dissolution, liquidation or winding
up of the affairs of the Trust shall, subject to any 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 Preferred Shares
shall not be entitled to share therein.

         8. Auction Agent. For so long as any Preferred Shares are Outstanding,
the Auction Agent, duly appointed by the Trust to so act, shall be in each case
a commercial bank, trust company or other financial institution independent of
the Trust and its Affiliates (which, however, may engage or have engaged in
business transactions with the Trust or its Affiliates) and at no time shall the
Trust 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 any Series are
Outstanding, the Trust 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.

         9. 1940 Act Preferred Shares Asset Coverage. The Trust shall maintain,
as of the last Business Day of each month in which any Preferred Shares are
Outstanding, the 1940 Act Preferred Shares Asset Coverage; provided, however,
that Section 3(a)(ii) shall be the sole remedy in the event the Trust fails to
do so.

         10. Preferred Shares Basic Maintenance Amount. So long as any Preferred
Shares are Outstanding and any Rating Agency so requires, the Trust shall
maintain, as of each Valuation Date, Moody's Eligible Assets and Fitch Eligible
Assets, as applicable, having an aggregate Discounted Value equal to or greater
than the Preferred Shares Basic Maintenance Amount; provided, however, that
Section 3(a)(ii) shall be the sole remedy in the event the Trust fails to do so.

         11. Certain Other Restrictions. So long as any Preferred Shares are
Outstanding and Fitch, Moody's or any Other Rating Agency that is rating such
shares so requires, the Trust will not, unless it has received written
confirmation from Fitch (if Fitch is then rating the Preferred Shares), Moody's
(if Moody's is then rating the Preferred Shares) and (if applicable) such Other
Rating Agency, that any such action would not impair the rating then assigned by
such Rating Agency to the Preferred Shares, engage in any one or more of the
following transactions:

                  (a) purchase or sell futures contracts or options thereon with
respect to portfolio securities or write put or call options on portfolio
securities;

                  (b) except in connection with a refinancing of the Preferred
Shares, issue additional shares of any Series of preferred shares, including any
Series or reissue any preferred shares, including any Series previously
purchased or redeemed by the Trust;

                  (c) engage in any short sales of securities;

                  (d) lend portfolio securities;

                  (e) merge or consolidate into or with any other fund;




                                      A-14


                  (f) for purposes of valuation of Moody's Eligible Assets: (A)
if the Trust writes a call option, the underlying asset will be valued as
follows: (1) if the option is exchange-traded and may be offset readily or if
the option expires before the earliest possible redemption of the Preferred
Shares, at the lower of the Discounted Value of the underlying security of the
option and the exercise price of the option or (2) otherwise, it has no value;
(B) if the Trust writes a put option, the underlying asset will be valued as
follows: the lesser of (1) exercise price and (2) the Discounted Value of the
underlying security; and (C) call or put option contracts which the Trust buys
have no value. For so long as the Preferred Shares are rated by Moody's: (A) the
Trust will not engage in options transactions for leveraging or speculative
purposes; (B) the Trust will not write or sell any anticipatory contracts
pursuant to which the Trust hedges the anticipated purchase of an asset prior to
completion of such purchase; (C) the Trust will not enter into an option
transaction with respect to portfolio securities unless, after giving effect
thereto, the Trust would continue to have Eligible Assets with an aggregate
Discounted Value equal to or greater than the Preferred Shares Basic Maintenance
Amount; (D) the Trust will not enter into an option transaction with respect to
portfolio securities unless after giving effect to such transaction the Trust
would continue to be in compliance with the provisions relating to the Preferred
Shares Basic Maintenance Amount; (E) for purposes of the Preferred Shares Basic
Maintenance Amount assets in margin accounts are not Eligible Assets; (F) the
Trust shall write only exchange-traded options on exchanges approved by Moody's
(if Moody's is then rating the Preferred Shares); (G) where delivery may be made
to the Trust with any of a class of securities, the Trust shall assume for
purposes of the Preferred Shares Basic Maintenance Amount that it takes delivery
of that security which yields it the least value; (H) the Trust will not engage
in forward contracts; and (I) there shall be a quarterly audit made of the
Trust's options transactions by the Trust's independent auditors to confirm that
the 's is in compliance with these standards; or

                  (g) For so long as any Preferred Shares are rated by Fitch,
the Trust will not purchase or sell futures contracts, write, purchase or sell
options on futures contracts or write put options (except covered put options)
or call options (except covered call options) on portfolio securities unless it
receives written confirmation from Fitch that engaging in such transactions will
not impair the ratings then assigned to the Preferred Shares by Fitch.

         12. Compliance Procedures for Asset Maintenance Tests. For so long as
any Preferred Shares are Outstanding and any Rating Agency so requires:

                  (a) As of each Valuation Date, the Trust shall determine (i)
the Market Value of each Eligible Asset owned by the Trust on that date, (ii)
the Discounted Value of each such Eligible Asset, (iii) whether the Preferred
Shares Basic Maintenance Amount Test is met as of that date, (iv) the value (as
used in the 1940 Act) of the total assets of the Trust, less all liabilities,
and (v) whether the 1940 Act Preferred Shares Asset Coverage is met as of that
date.

                  (b) Upon any failure to meet the Preferred Shares Basic
Maintenance Amount Test or 1940 Act Preferred Shares Asset Coverage on any
Valuation Date, the Trust may use reasonable commercial efforts (including,
without limitation, altering the composition of its portfolio, purchasing
Preferred Shares outside of an Auction or, in the event of a failure to file a
certificate on a timely basis, submitting the requisite certificate), to meet
(or certify in the case of a failure to file a certificate on a timely basis, as
the case may be) the Preferred Shares Basic Maintenance Amount Test or 1940 Act
Preferred Shares Asset Coverage on or prior to the Asset Coverage Cure Date.

                  (c) Compliance with the Preferred Shares Basic Maintenance
Amount and 1940 Act Asset Coverage Tests shall be determined with reference to
those Preferred Shares which are deemed to be Outstanding hereunder.


                                      A-15


              (d) In the case of the asset coverage requirements for Moody's and
Fitch, the auditors must certify once per quarter the asset coverage test on a
date randomly selected by the auditor.

              (e) The Trust shall deliver to the Auction Agent and each Rating
Agency a certificate which sets forth a determination of items (i)-(iii) of
paragraph (a) of this Section 12 (a "Preferred Shares Basic Maintenance
Certificate") as of (A) the Date of Original Issue, (B) the last Valuation Date
of each month, (C) any date requested by any Rating Agency, (D) a Business Day
on or before any Asset Coverage Cure Date relating to the Trust's cure of a
failure to meet the Preferred Shares Basic Maintenance Amount Test, (E) any day
that Common Shares or Preferred Shares are redeemed and (F) any day the Fitch
Eligible Assets have an aggregate discounted value less than or equal to 110% of
the Preferred Shares Basic Maintenance Amount. Such Preferred Shares Basic
Maintenance Certificate shall be delivered in the case of clause (i)(A) on the
Date of Original Issue and in the case of all other clauses above on or before
the seventh Business Day after the relevant Valuation Date or Asset Coverage
Cure Date.

              (f) The Trust shall deliver to the Auction Agent and each Rating
Agency a certificate which sets forth a determination of items (iv) and (v) of
paragraph (a) of this Section 12 (a "1940 Act Preferred Shares Asset Coverage
Certificate") (i) as of the Date of Original Issue, and (ii) as of (A) the last
Valuation Date of each quarter thereafter, and (B) as of a Business Day on or
before any Asset Coverage Cure Date relating to the failure to meet the 1940 Act
Preferred Shares Asset Coverage. Such 1940 Act Preferred Shares Asset Coverage
Certificate shall be delivered in the case of clause (i) on the Date of Original
Issue and in the case of clause (ii) on or before the seventh Business Day after
the relevant Valuation Date or the Asset Coverage Cure Date. The certificates
required by paragraphs (d) and (e) of this Section 12 may be combined into a
single certificate.

              (g) Within ten Business Days of the Date of Original Issue, the
Trust shall deliver to the Auction Agent and each Rating Agency a letter
prepared by the Trust's independent auditors (an "Auditor's Certificate")
regarding the accuracy of the calculations made by the Trust in the Preferred
Shares Basic Maintenance Certificate and the 1940 Act Preferred Shares Asset
Coverage Certificate required to be delivered by the Trust on the Date of
Original Issue. Within ten Business Days after delivery of the Preferred Shares
Basic Maintenance Certificate and the 1940 Act Preferred Shares Asset Coverage
Certificate relating to the last Valuation Date of each fiscal quarter of the
Trust, the Trust will deliver to the Auction Agent and each Rating Agency an
Auditor's Certificate regarding the accuracy of the calculations made by the
Trust in such Certificates and in one other Preferred Shares Basic Maintenance
Certificate randomly selected by the Trust's independent auditors during such
fiscal quarter. In addition, the Trust will deliver to the persons specified in
the preceding sentence an Auditor's Certificate regarding the accuracy of the
calculations made by the Trust on each Preferred Shares Basic Maintenance
Certificate and 1940 Act Preferred Shares Asset Coverage Certificate delivered
in relation to an Asset Coverage Cure Date within ten days after the relevant
Asset Coverage Cure Date. If an Auditor's Certificate shows that an error was
made in any such report, the calculation or determination made by the Trust's
independent auditors will be conclusive and binding on the Trust.

              (h) The Auditor's Certificates referred to in paragraph (f) above
will confirm, based upon the independent auditor's review of portfolio data

                                      A-27

                  (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

              (c) If an Order or Orders covering all of the Outstanding
Preferred Shares of a 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 Dividend
Period consisting of more than 91 Dividend Period days, the Auction Agent shall
deem a Sell Order to have been submitted by or on behalf of such Existing Holder

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

                  (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

                                      A-28


         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.

              (e) If more than one Bid for one or more shares of a Series of
Preferred Shares 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.

         4.   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 a Series of Preferred Shares, 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:

                                      A-29


                  (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 Preferred Shares" 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 all
              Dividend Periods) 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 all Dividend Periods)
              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); and

                  (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
              Preferred Shares of such series.

              (b) Promptly after the Auction Agent has made the determinations
pursuant to paragraph (a) of this Section 4, the Auction Agent shall advise the
Trust of the Maximum Rate for shares of the Series of Preferred Shares for which
an Auction is being held on the Auction Date and, based on such determination,
the Applicable Rate for shares of such Series For the next succeeding Dividend
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 Dividend 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),

                                      A-30


         that the Applicable Rate for all shares of such Series For the next
         succeeding Dividend 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 Dividend Period thereof
         shall be the All Hold Rate.

         5.   Acceptance and Rejection of Submitted Bids and Submitted Sell
Orders and Allocation. Existing Holders shall continue to hold the Preferred
Shares that are subject to Submitted Hold Orders, and, based on the
determinations made pursuant to paragraph (a) of Section 4 of this Part II, 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 a Series of
Preferred Shares 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 5, Submitted Bids with respect to shares
of such 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 Preferred Shares 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 Preferred Shares 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 Holder's 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 the Preferred Shares subject to such
         Submitted Bid, unless the number of Outstanding Preferred Shares
         subject to all such Submitted Bids shall be greater than the number of
         Preferred Shares ("remaining shares") in the excess of the Available
         Preferred Shares of such Series over the number of Preferred Shares
         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 Preferred Shares subject to such Submitted
         Bid, but only in an amount equal to the Preferred Shares of such Series
         obtained by multiplying the number of remaining shares by a fraction,
         the numerator of which shall be the number of Outstanding Preferred
         Shares held by such Existing Holder subject to such Submitted Bid and
         the denominator of which shall be the aggregate number of Outstanding
         Preferred Shares subject to such Submitted Bids made by 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 for
         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 Preferred Shares of such
         Series over the number

                                      A-31


         of Preferred Shares 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 Preferred Shares subject to
         such Submitted Bid and the denominator of which shall be the aggregate
         number of Outstanding Preferred Shares 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 a Series of
Preferred Shares 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 5, Submitted Orders for shares of
such series shall be accepted or rejected as follows in the following order of
priority and all other Submitted Bids for shares of such Series shall be
rejected:

                  (i)   Existing 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 rejected, thus entitling such
         Existing Holders to continue to hold the Preferred Shares 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

                  (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 a Series of Preferred
Shares 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 5, 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 a Series of
Preferred Shares 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
Preferred Shares 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 a Series of Preferred
Shares.

              (e) If, as a result of the procedures described in clause (v) of
paragraph (a) of this Section 5 any Potential Holder would be entitled or
required to purchase less than a whole share of a Series of Preferred Shares on
any Auction Date, the Auction Agent shall, in such manner as it shall determine
in its sole discretion, allocate Preferred Shares of such Series For purchase
among Potential Holders so that only whole Preferred Shares of such Series are
purchased on such Auction Date as a result

                                      A-32


of such procedures by any Potential Holder, even if such allocation results in
one or more Potential Holders not purchasing Preferred Shares of such Series on
such Auction Date.

              (f) Based on the results of each Auction for shares of a Series of
Preferred Shares, 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, Preferred Shares 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 a Series of Preferred Shares 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 Preferred
Shares 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 Trust 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 Preferred Shares of
any Series or to pay for Preferred Shares of any Series sold or purchased
pursuant to the Auction Procedures or otherwise.

         6.   Transfer of Preferred Shares. Unless otherwise permitted by the
Trust, a Beneficial Owner or an Existing Holder may sell, transfer or otherwise
dispose of Preferred Shares 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 Part II or to a Broker-Dealer; provided, however, that (a) a
sale, transfer or other disposition of Preferred Shares 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 6 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 Trust) to whom
such transfer is made shall advise the Auction Agent of such transfer.

                     APPENDIX B -- DESCRIPTION OF RATINGS(1)

MOODY'S PRIME RATING SYSTEM

         Moody's short-term ratings are opinions of the ability of issuers to
honor senior financial obligations and contracts. Such obligations generally
have an original maturity not exceeding one year, unless explicitly noted.

         Moody's employs the following designations, all judged to be investment
grade, to indicate the relative repayment ability of rated issuers:

         PRIME-1: Issuers rated Prime-1 (or supporting institutions) have a
superior ability for repayment of senior short-term debt obligations. Prime-1
repayment ability will often be evidenced by many of the following
characteristics:

         Leading market positions in well-established industries. High rates of
return on funds employed. Conservative capitalization structure with moderate
reliance on debt and ample asset protection. Broad margins in earnings coverage
of fixed financial charges and high internal cash generation. Well-established
access to a range of financial markets and assured sources of alternate
liquidity.

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

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

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

         In addition, in certain countries the prime rating may be modified by
the issuer's or guarantor's senior unsecured long-term debt rating.

MOODY'S DEBT RATINGS

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

         Aa: Bonds and preferred stock 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.

------------------
(1) The ratings indicated herein are believed to be the most recent ratings
available at the date of this prospectus for the securities listed. Ratings are
generally given to securities at the time of issuance. While the rating agencies
may from time to time revise such ratings, they undertake no obligation to do
so, and the ratings indicated do not necessarily represent ratings which will be
given to these securities on the date of the fund's fiscal year-end.


                                      B-1


They are rated lower than the best bonds because margins of protection may not
be as large as in Aaa securities or fluctuation of protective elements may be of
greater amplitude or there may be other elements present which make the
long-term risk appear somewhat larger than the Aaa securities.

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

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

         Ba: Bonds and preferred stock 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 and preferred stock 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 and preferred stock 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 and preferred stock 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 and preferred stock 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.

         Moody's assigns ratings to individual debt securities issued from
medium-term note (MTN) programs, in addition to indicating ratings to MTN
programs themselves. Notes issued under MTN programs with such indicated ratings
are rated at issuance at the rating applicable to all pari passu notes issued
under the same program, at the program's relevant indicated rating, provided
such notes do not exhibit any of the characteristics listed below. For notes
with any of the following characteristics, the rating of the individual note may
differ from the indicated rating of the program:

               1)   Notes containing features which link the cash flow and/or
                    market value to the credit performance of any third party or
                    parties.

               2)   Notes allowing for negative coupons, or negative principal.

               3)   Notes containing any provision which could obligate the
                    investor to make any additional payments.

         Market participants must determine whether any particular note is
rated, and if so, at what rating level.


                                      B-2


         Note: Moody's applies numerical modifiers 1, 2, and 3 in each generic
rating classification from Aa through Caa. The modifier 1 indicates that the
obligation ranks in the higher end of its generic rating category; the modifier
2 indicates a mid-range ranking; and the modifier 3 indicates a ranking in the
lower end of that generic rating category.

STANDARD & POOR'S SHORT-TERM ISSUE CREDIT RATINGS

         A-1: A short-term obligation rated A-1 is rated in the highest category
by Standard & Poor's. The obligor's capacity to meet its financial commitment on
the obligation is strong. Within this category, certain obligations are
designated with a plus sign (+). This indicates that the obligor's capacity to
meet its financial commitment on these obligations is extremely strong.

         A-2: A short-term obligation rated A-2 is somewhat more susceptible to
the adverse effects of changes in circumstances and economic conditions than
obligations in higher rating categories. However, the obligor's capacity to meet
its financial commitment on the obligation is satisfactory.

         A-3: A short-term obligation rated A-3 exhibits adequate protection
parameters. However, adverse economic conditions or changing circumstances are
more likely to lead to a weakened capacity of the obligor to meet its financial
commitment on the obligation.

         B: A short-term obligation rated B is regarded as having significant
speculative characteristics. The obligor currently has the capacity to meet its
financial commitment on the obligation; however, it faces major ongoing
uncertainties which could lead to the obligor's inadequate capacity to meet its
financial commitment on the obligation.

         C: A short-term obligation rated C is currently vulnerable to
nonpayment and is dependent upon favorable business, financial, and economic
conditions for the obligor to meet its financial commitment on the obligation.

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

STANDARD & POOR'S LONG-TERM ISSUE CREDIT RATINGS

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

         -    Likelihood of payment-capacity and willingness of the obligor to
              meet its financial commitment on an obligation in accordance with
              the terms of the obligation;

         -    Nature of and provisions of the obligation;

         -    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.

         The issue rating definitions are expressed in terms of default risk. As
such, they pertain to senior obligations of an entity. Junior obligations are
typically rated lower than senior obligations, to reflect the lower priority in
bankruptcy, as noted above. (Such differentiation applies when an entity has
both senior and subordinated obligations, secured and unsecured obligations, or
operating company and holding

                                      B-3


company obligations.) Accordingly, in the case of junior debt, the rating may
not conform exactly with the category definition.

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

         AA: An obligation rated AA differs from the highest rated obligations
only in small degree. The obligor's capacity to meet its financial commitment on
the obligation is very strong.

         A: An obligation rated A is somewhat more susceptible to the adverse
effects of changes in circumstances and economic conditions than obligations in
higher rated categories. However, the obligor's capacity to meet its financial
commitment on the obligation is still strong.

         BBB: An obligation rated BBB exhibits adequate protection parameters.
However, adverse economic conditions or changing circumstances are more likely
to lead to a weakened capacity of the obligor to meet its financial commitment
on the obligation.

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

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

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

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

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

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

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

                                      B-4


         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.

         r: This symbol is attached to the ratings of instruments with
significant noncredit risks. It highlights risks to principal or volatility of
expected returns which are not addressed in the credit rating.

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

LOCAL CURRENCY AND FOREIGN CURRENCY RISKS

         Country risk considerations are a standard part of Standard & Poor's
analysis for credit ratings on any issuer or issue. Currency of repayment is a
key factor in this analysis. An obligor's capacity to repay foreign currency
obligations may be lower than its capacity to repay obligations in its local
currency due to the sovereign government's own relatively lower capacity to
repay external versus domestic debt. These sovereign risk considerations are
incorporated in the debt ratings assigned to specific issues. Foreign currency
issuer ratings are also distinguished from local currency issuer ratings to
identify those instances where sovereign risks make them different for the same
issuer.

ITEM 29.  INDEMNIFICATION

         The Registrant's Agreement and Declaration of Trust (the
"Declaration"), dated April 17, 2002, provides that every person who is, or has
been, a Trustee or an officer, employee or agent of the Registrant (including
any individual who serves at its request as director, officer, partner,
employee, Trustee, agent or the like of another organization in which it has any
interest as a shareholder, creditor or otherwise) ("Covered Person") shall be
indemnified by the Registrant or the appropriate series of the Registrant to the
fullest extent permitted by law against liability and against all expenses
reasonably incurred or paid by him in connection with any claim, action, suit or
proceeding in which he becomes involved as a party or otherwise by virtue of his
being or having been a Covered Person and against amounts paid or incurred by
him in the settlement thereof; provided that no indemnification shall be
provided to a Covered Person (i) who shall have been adjudicated by a court or
body before which the proceeding was brought (A) to be liable to the Registrant
or its shareholders by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his
office, or (B) not to have acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the
Registrant; or (ii) in the event of a settlement, unless there has been a
determination that such Covered Person did not engage in willful misfeasance,
bad faith, gross negligence or reckless disregard of the duties involved in the
conduct of his office; (A) by the court or other body approving the settlement;
(B) by at least a majority of those Trustees who are neither Interested Persons
of the Trust nor are parties to the matter based upon a review of readily
available facts (as opposed to a full trial-type inquiry); (C) by written
opinion of independent legal counsel based upon a review of readily available
facts (as opposed to a full trial-type inquiry) or (D) by a vote of a majority
of the Outstanding Shares entitled to vote (excluding any Outstanding Shares
owned of record or beneficially by such individual).

         The Declaration also provides that if any Shareholder or former
Shareholder of any series of the Registrant shall be held personally liable
solely by reason of his being or having been a shareholder and not because of
his acts or omissions or for some other reason, the Shareholder or former
Shareholder (or his heirs, executors, administrators or other legal
representatives or in the case of any entity, its general successor) shall be
entitled out of the assets belonging to the applicable series of the Registrant
to be held harmless from and indemnified against all loss and expense arising
from such liability. The Registrant, on behalf of its affected series, shall,
upon request by such Shareholder, assume the defense of any claim made against
such Shareholder for any act or obligation of the series and satisfy any
judgment thereon from the assets of the series.

         Insofar as indemnification for liability arising under the Securities
Act of 1933, as amended (the "1933 Act"), may be available 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 SEC
such indemnification is against public policy as expressed in the 1933 Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant's 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 whether such indemnification by it is against public
policy as expressed in the 1933 Act and will be governed by the final
adjudication of such issue.

         The registrant, its trustees and officers, its investment adviser, the
other investment companies advised by the adviser and certain persons affiliated
with them are insured, within the limits and subject to the limitations of the
insurance, against certain expenses in connection with the defense of actions,
suits or proceedings, and certain liabilities that might be imposed as a result
of such actions, suits or

                                      C-3


proceedings. The insurance expressly excludes coverage for any trustee or
officer whose personal dishonesty, fraudulent breach of trust, lack of good
faith, or intention to deceive or defraud has been finally adjudicated or may be
established or who willfully fails to act prudently.

ITEM 33.  UNDERTAKINGS

         1.   The Registrant undertakes to suspend the offering of shares until
              the prospectus is amended if (1) subsequent to the effective date
              of its registration statement, the net asset value declines more
              than ten percent from its net asset value as of the effective date
              of the registration statement or (2) the net asset value increases
              to an amount greater than its net proceeds as stated in the

         2.   Not applicable.

         3.   Not applicable.

         4.   Not applicable.

         5.   (a)   For the purposes of determining any liability under the 1933
                    Act, the information omitted from the form of prospectus
                    filed as part of a registration statement in reliance upon
                    Rule 430A and contained in the form of prospectus filed by
                    the Registrant under Rule 497(h) under the 1933 Act shall be
                    deemed to be part of the Registration Statement as of the
                    time it was declared effective.

              (b)   For the purpose of determining any liability under the 1933
                    Act, each post-effective amendment that contains a form of
                    prospectus shall be deemed to be a new registration
                    statement relating to the securities offered therein, and
                    the offering of the securities at that time shall be deemed
                    to be the initial bona fide offering thereof.

         6.   The Registrant undertakes to send by first class mail or other
              means designed to ensure equally prominent delivery within two
              business days of receipt of a written or oral request the
              Registrant's statement of additional information.
