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 primarily in common and preferred stocks, convertible securities and income producing securities such as investment grade and below investment grade (high yield/high risk) debt securities. The Fund, under normal circumstances, will invest at least 50% of its managed assets in equity securities (including securities that are convertible into equity securities). The Fund may invest up to 35% of its managed 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. The Fund may invest up to 15% of its managed assets in securities of foreign issuers in emerging markets. "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. 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 Corporation, a division of The McGraw-Hill Companies ("S&P") 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 securities. There can be no assurance that the Fund will achieve its investment objective. ------------------ INVESTING IN THE FUND'S PREFERRED SHARES INVOLVES RISKS.

The Fund is offering 7,040 shares of Series M Preferred Shares, 7,040 shares of Series TU Preferred Shares, 7,040 shares of Series W Preferred Shares, 7,040 shares of Series TH Preferred Shares, 7,040 shares of Series F Preferred Shares, 4,000 shares of Series A Preferred Shares and 4,000 shares of Series B Preferred Shares. The shares are referred to in this prospectus as "Preferred Shares." The Preferred Shares have a liquidation preference of $25,000 per share, plus any accumulated, unpaid dividends. The Preferred Shares also have priority over the Fund's common shares as to distribution of assets as described in this prospectus. It is a condition of closing this offering that the Preferred Shares be offered with a rating of "AAA" from Fitch and "AAA" from S&P. The dividend rate for the initial dividend period will be 1.15% for Series M, 1.15% for Series TU, 1.15% for Series W, 1.15% for Series TH, 1.15% for Series F, 1.15% for Series A, and 1.15% for Series B. The initial dividend period is from the date of issuance through May 17, 2004 for Series M, May 18, 2004 for Series TU, May 19, 2004 for Series W, May 13, 2004 for Series TH, May 16, 2004 for Series F, June 2, 2004 for Series A and June 3, 2004 for Series B. Series M, TU, W, TH and F will have initial dividend periods of 11, 12, 13, 7 and 10 days, respectively. Series A and B will have initial dividend periods of 27 and 28 days, respectively. For subsequent dividend periods, Preferred Shares pay dividends based on a rate set at auction, usually held weekly in the case of Series M, TU, W, TH and F or every 28 days in the case of Series A and B. Dividends on the Preferred Shares will be cumulative. Prospective purchasers should carefully review the auction procedures described in this prospectus and should note: (1) a buy order (called a "bid order") or sell order is a commitment to buy or sell Preferred Shares based on the results of an auction; (2) auctions will be conducted by telephone; and (3) purchases and sales will be settled on the next business day after the auction. The Preferred Shares are redeemable, in whole or in part, at the option of the Fund on the second business day prior to any date dividends are paid on the Preferred Shares, and will be subject to mandatory redemption in certain circumstances at a redemption price of $25,000 per share, plus accumulated, unpaid dividends to the date of redemption, plus a premium in certain circumstances. The Preferred Shares will not be listed on an exchange. You may only buy or sell Preferred Shares through an order placed at an auction with or through a broker-dealer that has entered into an agreement with the auction agent and the Trust or in a secondary market maintained by certain broker-dealers. These broker-dealers are not required to maintain this market, and it may not provide you with liquidity. The Preferred Shares do not represent a deposit or obligation of, and are not guaranteed or endorsed by, any bank or other insured depository institution and are not federally insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board or any other government agency. YOU SHOULD RELY ONLY ON THE INFORMATION CONTAINED OR INCORPORATED BY REFERENCE IN THIS PROSPECTUS.

This summary may not contain all of the information that you should consider before investing in the Fund's Preferred Shares. You should review the more detailed information contained in this prospectus and in the Statement of Additional Information, especially the information set forth under the heading "Risk Factors." The Fund...................... Calamos Strategic Total Return Fund is a recently organized, diversified, closed-end management investment company. Throughout the prospectus, we refer to Calamos Strategic Total Return Fund as the "Fund" or as "we," "us," or "our." See "The Fund." The Fund's common shares are traded on the New York Stock Exchange under the symbol "CSQ." As of April 26, 2004, the Fund had 154,514,000 common shares outstanding and net assets of $2,198,800,041. The Fund's principal offices are located at 1111 East Warrenville Road, Naperville, Illinois 60563. The Offering.................. We are offering 7,040 Series M Preferred Shares, 7,040 Series TU Preferred Shares, 7,040 Series W Preferred Shares, 7,040 Series TH Preferred Shares, 7,040 Series F Preferred Shares, 4,000 Series A Preferred Shares and 4,000 Series B Preferred Shares, each at a purchase price of $25,000 per share. The Preferred Shares are offered through a group of underwriters led by Citigroup Global Markets Inc. 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 M, TU, W, TH and F Preferred Shares will each be seven days and for the Series A and B Preferred Shares the dividend period 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 dividend period. See "The Auction." 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 investment, and the investor's liquidity preference. Investors can choose between seven tranches. 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 "The Fund's Investments -- Investment Objective." 1 Investment Policies........... PRIMARY INVESTMENTS. Under normal circumstances, the Fund will invest primarily in common and preferred stocks, convertible securities and income producing securities such as investment grade and below investment grade (high yield/high risk) debt securities. The Fund, under normal circumstances, will invest at least 50% of its managed assets in equity securities (including securities that are convertible into equity securities). The Fund may invest up to 35% of its managed 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. The Fund may invest up to 15% of its managed assets in securities of foreign issuers in emerging markets. "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. See "The Fund's Investments -- Principal Investment Strategies." Calamos will dynamically allocate the Fund's investments among multiple asset classes (rather than maintaining a fixed or static allocation), seeking to obtain an appropriate balance of risk and reward through all market cycles using multiple strategies and combining them to seek to achieve favorable risk adjusted returns. See "The Fund's Investments -- Principal Investment Strategies." EQUITY SECURITIES. Equity securities include common and preferred stocks, warrants, rights, and depository receipts. Under normal circumstances, the Fund will invest at least 50% of its managed assets in equity securities (including securities that are convertible into equity securities). The Fund may invest in preferred stock and convertible securities of any rating, including below investment grade. See "High Yield Securities" below. An investment in the equity securities of a company represents a proportionate ownership interest in that company. Therefore, the Fund participates in the financial success or failure of any company in which it has an equity interest. See "The Fund's Investments -- Principal Investment Strategies -- Equity Securities." HIGH YIELD SECURITIES. The Fund may invest in high yield securities for either current income or capital appreciation or both. These securities are rated Ba or lower by Moody's or BB or lower by S&P or are unrated securities of comparable quality as determined by Calamos Asset Management, Inc. ("Calamos"), the Fund's investment adviser. The Fund may invest in high yield securities of any rating. Non-convertible 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 securities. See "The Fund's Investments -- Principal Investment Strategies -- High Yield Securities." 2 FOREIGN ISSUERS. Although the Fund primarily invests in securities of U.S. issuers, the Fund may invest up to 35% of its managed 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. The Fund may invest up to 15% of its managed assets in securities of foreign issuers in 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 these percentage limitations, foreign securities do not include securities represented by American Depository Receipts ("ADRs") or securities guaranteed by a U.S. person. See "The Fund's Investments -- Principal Investment Strategies -- Foreign Securities." CONVERTIBLE SECURITIES. The Fund may invest in convertible securities. A convertible security is a debt security or preferred stock that is exchangeable for an equity security (typically of the same 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. The Fund may invest in convertible securities of any rating. Securities that are convertible into equity securities are considered equity securities for purposes of the Fund's policy to invest at least 50% of its managed assets in equity securities. See "The Fund's Investments -- 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 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 equity securities for purposes of the Fund's policy to invest at least 50% of its managed assets in equity securities. See "The Fund's Investments -- Principal Investment Strategies -- Synthetic Convertible Securities." 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"). Calamos, under the supervision of the Board of Trustees, will determine whether 3 securities purchased under Rule 144A are illiquid (that is, not readily marketable) and thus subject to the Fund's limit on investing no more than 15% of its managed assets in illiquid securities. See "The Fund's Investments -- Principal Investment Strategies -- Rule 144A Securities." 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 investments may experience greater volatility in market value than U.S. government or other 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 opportunity to purchase additional income producing assets with the liquidation proceeds. 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. See "The Fund's Investments -- Principal Investment Strategies -- Zero Coupon Securities." OTHER SECURITIES. The Fund may invest in other securities of various types. Normally, the Fund invests substantially all of its assets to meet its investment objective. 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 "The Fund's Investments -- Principal Investment Strategies." 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 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 38% of the Fund's total assets. However, the Board of Trustees reserves 4 the right to issue preferred shares and Borrowings to the extent permitted by the Investment Company Act of 1940 (the "1940 Act"). 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." Interest Rate Transactions.... In order to seek to reduce the interest rate risk inherent in the Fund's underlying investments and capital structure, the Fund, if market conditions are deemed favorable, likely will enter into interest rate swap or cap transactions to attempt to protect itself from increasing dividend or interest expenses on its leverage. The use of interest rate swaps and caps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. In an interest rate swap, the Fund would agree to pay to the other party to the interest rate swap (which is known as the "counterparty") a fixed rate payment in exchange for the counterparty agreeing to pay to the Fund a payment at a variable rate that is expected to approximate the rate on any variable rate payment obligations on the Fund's leverage. The payment obligations would be based on the notional amount of the swap. The Fund's payment obligations under the swap are general unsecured obligations of the Fund and are ranked senior to distributions applicable to the common shares and the Preferred Shares. In an interest rate cap, the Fund would pay a premium to the counterparty to the interest rate cap and, to the extent that a specified variable rate index exceeds a predetermined fixed rate, would receive from the counterparty payments of the difference based on the notional amount of such cap. If the counterparty to an interest rate swap or cap defaults, the Fund would be obligated to make the payments that it had intended to avoid. Depending on the state of interest rates in general, this default could negatively impact the Fund's ability to make dividend payments on the Preferred Shares. In addition, at the time an interest rate swap or cap transaction reaches its scheduled termination date, there is a risk that the Fund would not be able to obtain a replacement transaction or that the terms of the replacement would not be as favorable as on the expiring transaction. If this occurs, it could have a negative impact on the Fund's ability to make dividend payments on the Preferred Shares or interest payments on Borrowings. If the Fund fails to meet an asset coverage ratio required by law or if the Fund does not meet a rating agency guideline in a timely manner, the Fund may be required to redeem some or all of the Preferred Shares. See "Redemption" below. Similarly, the Fund 5 could be required to prepay the principal amount of Borrowings, if any. Such redemption or prepayment would likely result in the Fund seeking to terminate early all or a portion of any swap or cap transaction. Early termination of a swap could result in a termination payment by or to the Fund. A termination payment by the Fund would result in a reduction in common share net earnings. Early termination of a cap could result in a termination payment to the Fund. The Fund intends to maintain in a segregated account with its custodian, cash or liquid securities having a value at least equal to the Fund's net payment obligations under any swap transaction, marked-to-market daily. Under certain circumstances, the Fund may be required to pledge the assets in such segregated account to the counter-party. The Fund will not enter into interest rate swap or cap transactions having a notional amount that exceeds the outstanding amount of the Fund's leverage. See "Interest Rate Transactions" for additional information. Investment Adviser............ Calamos is the Fund's investment adviser. Calamos is responsible on a day-to-day basis for investment of the Fund's portfolio in accordance with its investment objective and policies. Calamos makes all investment decisions for the Fund and places purchase and sale orders for the Fund's portfolio securities. As of March 31, 2004, Calamos managed approximately $29 billion in assets of individuals and institutions. Calamos is a wholly-owned subsidiary of Calamos Holdings, Inc. ("Holdings"). Holdings is controlled by John P. Calamos, who has been engaged in the investment advisory business since 1977. Portfolio Manager............. John P. Calamos, Nick P. Calamos and John P. Calamos, Jr. are responsible for managing the portfolio of the Fund. During the past five years, John P. Calamos has been a Chairman, CEO and Co-Chief Investment Officer of Calamos; Nick P. Calamos has been a Senior Executive Vice President and Co-Chief Investment Officer of Calamos; and John P. Calamos, Jr. has been an Executive Vice President of Calamos. Fund Accountant............... State Street Bank and Trust Company ("State Street"), will provide fund accounting and financial accounting services to the Fund. 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 dividend 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 an 6 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 at a time when it is not advantageous; - in certain 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 Fund" for a discussion of the general risks of the Fund's investment portfolio; and - certain events, such as terrorist attacks (including the terrorist attacks in the United States on September 11, 2001), war and other geopolitical events have led to increased short-term market volatility and may have long-term effects on U.S. and world economies and markets. The Fund cannot predict the effects of similar events in the future on the U.S. economy or other economies. Similar disruptions 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." In addition to the risks associated with investing in the Preferred Shares, an investor in the Preferred Shares will also be subject to the general risks associated with the Fund's investment policies, including the risks associated with equity securities, convertible 7 securities, high yield securities and foreign securities. These and other general risks of the Fund are described in more detail in "Risk Factors -- General Risks of Investing in the Fund." 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 M, TU, W, TH and F and every 28 days for the Series A and B 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 be created or, if created, that it will provide shareholders with liquidity or that the trading price in any secondary market would be $25,000. 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 of the week on which each subsequent auction, if any, 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 dividend period for that series of Preferred Shares. The start date for subsequent dividend periods will normally be the business day following the auction date unless the then-current dividend period is a special dividend period or the first day of the subsequent dividend period is not a business day. SUBSEQUENT SERIES FIRST AUCTION DATE* AUCTION DAY ------ ------------------- --------------------------------- M.... May 17 Monday TU... May 18 Tuesday W.... May 19 Wednesday TH... May 13 Thursday F.... May 14 Friday A.... June 2 Every fourth Wednesday thereafter B....

The table below shows the initial dividend rates, the dividend payment dates and the day of the week upon which subsequent dividends, if any, will be paid for each series and the number of days for the initial dividend periods on each series of Preferred Shares offered in this prospectus. For subsequent dividend 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 M, TU, W, TH and F and every 28 days in the case of Series A and B. In most instances, dividends are payable on the first business day following the end of the dividend period. The rate set at auctions will not exceed the maximum rate. See "Description of Preferred Shares -- Dividends and Dividend Periods." 8 INITIAL DATE OF NUMBER OF DAYS DIVIDEND ACCUMULATION DIVIDEND PAYMENT DAY FOR OF INITIAL SERIES RATE AT INITIAL RATE* INITIAL DIVIDEND PERIOD* SUBSEQUENT DIVIDEND PAYMENT DATE DIVIDEND PERIOD ------ -------- ---------------- ---------------------------- -------------------------------- --------------- M.... 1.15% May 7 May 18 Tuesday 11 TU... 1.15 May 7 May 19 Wednesday 12 W.... 1.15 May 7 May 20 Thursday 13 TH... 1.15 May 7 May 14 Friday 7 F.... 1.15 May 7 May 17 Monday 10 A.... 1.15 May 7 June 3 Every fourth Thursday thereafter 27 B.... 1.15 May 7 June 4 Every fourth Friday thereafter 28 ------------------- * All dates are 2004. Dividends on the Preferred Shares will be cumulative from the date the shares are first issued and will be paid out of legally available funds. The Fund may, subject to certain conditions, designate special dividend periods of more than seven or 28 days. A requested special dividend period will not be effective unless sufficient clearing bids were made in the auction immediately preceding the special dividend period. 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. In addition, the Fund does not intend to designate a special dividend period if such designation would adversely affect Fitch or S&P or any substitute rating agency's then-current rating on the Preferred Shares. The dividend payment date for special dividend periods will be set out in the notice designating a special dividend period. See "Description of Preferred Shares -- Dividends and Dividend Periods -- Designation of Special Dividend Periods" and "The Auction." Determination of Maximum Rate.......................... Except during a default period, the applicable rate for any dividend period for Preferred Shares will not be more than the maximum rate. The maximum rate for the Preferred Shares will depend on the credit rating assigned to such Preferred Shares and on the duration of the dividend period. The maximum rate will be the applicable percentage of the reference rate. The reference rate is the applicable LIBOR rate (for a dividend period of fewer than 365 days) or the applicable Treasury index rate (for a dividend period of 365 days or more). The applicable percentage is further subject to upward but not downward adjustment at the discretion of the Board of Trustees after consultation with the Broker-Dealers. There is no minimum rate in respect of any dividend period. See "Description of Preferred Shares -- Dividends and Dividend Periods." Ratings....................... The Fund will issue Preferred Shares only if such shares have received a credit quality rating of "AAA" from Fitch and "AAA" from S&P. 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 ratings do 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 9 S&P 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 -- Rating Agency Guidelines." 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 April 26, 2004, the asset coverage of the Preferred Shares as measured pursuant to the 1940 Act would be approximately 303% if the Fund were to issue all of the Preferred Shares offered in this Prospectus, representing approximately 33% 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 may also 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 distribution or redemption, the Fund would not have eligible portfolio holdings with an aggregated discounted value at least equal to any asset coverage requirements associated under 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. 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 does not 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 10 Shares -- Redemption" and "Description of Preferred Shares -- Rating Agency Guidelines." 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................. Except as otherwise indicated, holders of Preferred Shares have one vote per share. 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, including 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 1940 Act and Delaware law. See "Description of Preferred Shares -- Voting Rights," and "Certain Provisions in the Agreement and Declaration of Trust and By-Laws." Federal Income Taxes.......... Distributions with respect to the Preferred Shares will generally be subject to U.S. federal income taxation. A portion of such distributions may qualify for the dividends received deduction available to corporate holders or for treatment as "qualified dividend income" available to individual and other noncorporate holders. 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, capital gain dividends, dividends qualifying for the dividends received deduction and "qualified dividend income," if any, 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 "U.S. Federal Income Tax Matters." Custodian, Auction Agent, Transfer Agent, Dividend Paying Agent and Registrar.... The Bank of New York serves as custodian of the Fund's securities and cash. The Bank of New York also serves as auction agent with respect to the Preferred Shares, and transfer agent, dividend paying agent and registrar for the Fund's common shares and Preferred Shares. 11 FINANCIAL HIGHLIGHTS (UNAUDITED) Information contained in the table below shows the unaudited operating performance of the Fund from the commencement of the Fund's operations on March 26, 2004 through April 14, 2004. Since the Fund was recently organized and commenced operations on March 26, 2004, the table covers less than one month of operations, during which a substantial portion of the Fund's portfolio was held in temporary investments pending investment in securities that meet the Fund's investment objectives and policies. Accordingly, the information presented may not provide a meaningful picture of the Fund's future operating performance.

The Fund was organized under the laws of the state of Delaware on December 31, 2003, and has registered under the 1940 Act. On March 30, 2004, the Fund issued an aggregate of 140,500,000 common shares of beneficial interest, no par value, pursuant to the initial public offering and commenced its investment operations. The Fund granted the underwriters an option to purchase up to 19,800,000 additional common shares at the public offering price less the sales load. On April 20, 2004, the Fund issued an additional 14,000,000 common shares of beneficial interest in connection with a partial exercise by the underwriters of their over-allotment option. The underwriters may exercise the remaining portion of the over-allotment option through May 9, 2004, however, the underwriters do not anticipate that they will exercise any of the remaining portion of the over-allotment option. The Fund's common shares are traded on the New York Stock Exchange under the symbol "CSQ." The Fund's principal office is located at 1111 East Warrenville Road, Naperville, Illinois 60563-1493, and its telephone number is 1-800-582-6959. The following provides information about the Fund's authorized and outstanding shares as of April 20, 2004.

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 3 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 closed-end investment companies that invest primarily in the types of securities in which the Fund may invest directly.

The Fund's investment objective may be changed by the Board of Trustees without a shareholder vote, except that the Fund will give shareholders at least 60 days notice of any change to the Fund's investment objective. The Fund makes no assurance that it will realize its objective. An investment in the Fund may be speculative in that it involves a high degree of risk and should not constitute a complete investment program. See "Risk Factors." PRINCIPAL INVESTMENT STRATEGIES Under normal circumstances, the Fund will invest primarily in common and preferred stocks, convertible securities and income producing securities such as investment grade and below investment grade (high yield/high risk) debt securities. The Fund, under normal circumstances, will invest at least 50% of its managed assets in equity securities (including securities that are convertible into equity securities). The Fund may invest up to 35% of its managed 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. The Fund may invest up to 15% of its managed assets in securities of foreign issuers in emerging markets. Calamos will dynamically allocate the Fund's investments among multiple asset classes (rather than maintaining a fixed or static allocation), seeking to obtain an appropriate balance of risk and reward through all market cycles using multiple strategies and combining them to seek to achieve favorable risk adjusted returns. Calamos analyzes securities for the Fund's portfolio using an approach that focuses on assessing a total enterprise value before assessing the value of the securities issued by a company. Calamos seeks to assess the value of an issuer's total enterprise by studying its financial statements, including its balance sheet. Once enterprise value is determined, Calamos seeks to assess the value of the issuer's different types of securities, taking into account the business risk of the issuer, its competitive position and the seniority of each type of security relative to the rest of the issuer's capital structure. This approach serves as the basis for the Calamos research team's design and use of proprietary models which, along with risk management and portfolio construction techniques, assist in determining whether a given security presents an investment opportunity for the Fund. EQUITY SECURITIES. Equity securities include common and preferred stocks, warrants, rights, and depository receipts. Under normal circumstances, the Fund will invest at least 50% of its managed assets in equity securities (including securities that are convertible into equity securities). The Fund may invest in preferred stocks and convertible securities of any rating, including below investment grade. See "High Yield Securities" below. An investment in the equity securities of a company represents a proportionate ownership interest in that company. Therefore, the Fund participates in the financial success or failure of any company in which it has a equity interest. HIGH YIELD SECURITIES. The Fund may invest in high yield securities for either current income or capital appreciation or both. The high yield securities in which the Fund invests are rated Ba or lower by Moody's or BB or lower by S&Ps or are unrated but determined by Calamos to be of comparable quality. The Fund may invest in high yield securities of any rating. Non-convertible 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 non-convertible 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. OTHER INCOME SECURITIES. The Fund may also invest in investment grade income securities. The Fund's investments in investment grade 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. 15 FOREIGN SECURITIES. Although the Fund primarily invests in securities of U.S. issuers, the Fund may invest up to 35% of its managed 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. The Fund may invest up to 15% of its managed assets in securities of foreign issuers in 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 these percentage limitations, foreign securities do not include securities represented by American Depository Receipts ("ADRs") or securities guaranteed by a U.S. person. CONVERTIBLE SECURITIES. A convertible security is a debt security or preferred stock that is exchangeable for an equity security (typically of the same 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. The Fund may invest in convertible securities of any rating. Securities that are convertible into equity securities are considered equity securities for purposes of the Fund's policy to invest at least 50% of its managed assets in equity 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 options on a stock index. The Fund may also purchase synthetic securities created by other parties, typically investment banks, including convertible structured notes. Convertible structured notes are fixed income debentures linked to equity. 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. 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 equity securities for purposes of the Fund's policy to invest at least 50% of its managed assets in equity securities. 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"). Calamos, under the supervision of the Board of Trustees, will consider whether securities purchased under Rule 144A are illiquid and thus subject to the Fund's limit of investing no more than 15% of its managed assets in illiquid securities. A determination of whether a Rule 144A security is liquid or not is a question of fact. In making this determination, Calamos will consider the trading markets for the specific security, taking into account the unregistered nature of a Rule 144A security. In addition, Calamos could consider the (1) frequency of trades and quotes, (2) number of dealers and potential purchasers, (3) dealer undertakings to make a market and (4) nature of a security and of marketplace trades (e.g., the time needed to dispose of the security, the method of soliciting offers and the mechanics of transfer). The liquidity of Rule 144A securities will be monitored and, if as a result of changed conditions, it is determined that a Rule 144A security is no longer liquid, the Fund's holdings of illiquid securities would be reviewed to determine what, if any, steps are required to assure that the Fund does not invest more than 15% of its assets in illiquid securities. Investing in Rule 144A securities could have the effect of increasing the amount of the portfolio's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase such securities. 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, General Services Administration, Central 16 Bank for Cooperatives, Federal Farm Credit Banks, Federal Home Loan Banks, Federal Home Loan Mortgage Corporation, 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. 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. 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 investments may experience greater volatility in market value than U.S. government or other 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 opportunity to purchase additional income producing assets with the liquidation proceeds. 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. 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 are 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. TEMPORARY DEFENSIVE INVESTMENTS. Under unusual market or economic conditions or for other 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 17 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. During such periods, the Fund may not be able to achieve its investment objective. 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 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 could 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. 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 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 the 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. 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 money or issue debt securities. The Preferred Shares will have a liquidation preference of $25,000 per share plus an amount equal to accumulated but unpaid dividends. As a non-fundamental policy, such preferred shares, including Preferred Shares, or Borrowings may not exceed 38% of the Fund's total assets. However, the Board of Trustees reserves the right to issue preferred shares or borrow to the extent 18 permitted by the 1940 Act. Before issuing any additional preferred shares to increase its assets available for investment, the Fund must have received confirmation from Fitch and S&P 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 costs will be lower than the return the Fund achieves on its investments with the proceeds of the issuance of preferred shares or Borrowings. Such difference in return may result from the Fund's higher credit rating or the short-term nature of its borrowings compared to the long-term nature of its investments. Since the total assets of the Fund (including the assets obtained from leverage) may 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 any such 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 interest 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 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 Borrowings 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 would increase the cost of borrowing over the stated interest rate. Under the 1940 Act, the Fund is not permitted to issue preferred shares unless immediately after such issuance the net asset value of the Fund's portfolio is at least 200% of the liquidation value of the outstanding preferred shares (i.e., such liquidation value may not exceed 50% of the value of the Fund's total assets). In addition, the Fund is not permitted to declare any cash dividend or other distribution on its common shares unless, at the time of such declaration, the net asset value of the Fund's portfolio (determined after deducting the amount of such dividend or distribution) is at least 200% of such liquidation value. In the event preferred shares are issued, the Fund intends, to the extent possible, to purchase or redeem preferred shares from time to time to maintain coverage of any preferred shares of at least 200%. Under the 1940 Act, the Fund is not permitted to incur indebtedness unless immediately after such borrowing the Fund has an asset coverage of at least 300% of the aggregate outstanding principal balance of indebtedness (i.e., such indebtedness may not exceed 33 1/3% of the value of the Fund's total assets). Additionally, under the 1940 Act, the Fund may not declare any dividend or other distribution upon any class of its shares, or purchase any such shares, unless the aggregate indebtedness of the Fund has, at the time of the declaration of any such dividend or distribution or at the time of any such purchase, an asset coverage of at least 300% after deducting the amount of such dividend, distribution, or purchase price, as the case may be. 19 The Fund may be subject to certain restrictions on investments imposed by guidelines of one or more nationally recognized statistical 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. INTEREST RATE TRANSACTIONS In order to seek to reduce the interest rate risk inherent in the Fund's underlying investments and capital structure, the Fund likely will enter into interest rate swap or cap transactions. Interest rate swaps involve the Fund's agreement with the swap counterparty to pay a fixed rate payment in exchange for the counterparty agreeing to pay the Fund a variable rate payment that is expected to approximate the rate of any variable rate payment obligation on Preferred Shares or any variable rate borrowing. The payment obligations would be based on the notional amount of the swap. The Fund's payment obligations under the swap are general unsecured obligations of the Fund and are ranked senior to distributions under the common shares and Preferred Shares. The Fund may use an interest rate cap, which would require it to pay a premium to the cap counterparty and would entitle it, to the extent that a specified variable rate index exceeds a predetermined fixed rate, to receive from the counterparty payment of the difference based on the notional amount. The Fund would use interest rate swaps or caps only with the intent to reduce or eliminate the risk that an increase in short-term interest rates could have on common share net earnings as a result of leverage. The Fund will usually enter into swaps or caps on a net basis; that is, the two payment streams will be netted out in a cash settlement on the payment date or dates specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. The Fund intends to maintain in a segregated account with its custodian cash or liquid securities having a value at least equal to the Fund's net payment obligations under any swap transaction, marked-to-market daily. Under certain circumstances, the Fund may be required to pledge the assets in such segregated account to the counterparty. The use of interest rate swaps and caps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. Depending on the state of interest rates in general, the Fund's use of interest rate swaps or caps could enhance or harm the overall performance on the common shares. To the extent there is a decline in interest rates, the value of the interest rate swap or cap could decline, and could result in a decline in the net asset value of the common shares. In addition, if short-term interest rates are lower than the Fund's fixed rate of payment on the interest rate swap, the swap will reduce common share net earnings. If, on the other hand, short-term interest rates are higher than the fixed rate of payment on the interest rate swap, the swap will enhance common share net earnings. Buying interest rate caps could enhance the performance of the common shares by providing a maximum leverage expense. Buying interest rate caps could also decrease the net earnings of the common shares in the event that the premium paid by the Fund to the counterparty exceeds the additional amount the Fund would have been required to pay had it not entered into the cap agreement. The Fund has no current intention of selling an interest rate swap or 20 cap. The Fund will not enter into interest rate swap or cap transactions in an aggregate notional amount that exceeds the outstanding amount of the Fund's leverage. Interest rate swaps and caps do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that the Fund is contractually obligated to make. If the counterparty defaults, the Fund would not be able to use the anticipated net receipts under the swap or cap to offset the dividend payments on Preferred Shares or interest payments on Borrowings. Depending on whether the Fund would be entitled to receive net payments from the counterparty on the swap or cap, which in turn would depend on the general state of short-term interest rates at that point in time, such a default could negatively impact the performance of the common shares. Although this will not guarantee that the counterparty does not default, the Fund will not enter into an interest rate swap or cap transaction with any counterparty that Calamos believes does not have the financial resources to honor its obligation under the interest rate swap or cap transaction. Further, Calamos will continually monitor the financial stability of a counterparty to an interest rate swap or cap transaction in an effort to proactively protect the Fund's investments. In addition, at the time the interest rate swap or cap transaction reaches its scheduled termination date, there is a risk that the Fund will not be able to obtain a replacement transaction or that the terms of the replacement will not be as favorable as on the expiring transaction. If this occurs, it could have a negative impact on the performance of the common shares. The Fund may choose or be required to redeem some or all Preferred Shares or prepay any Borrowings. This redemption would likely result in the Fund seeking to terminate early all or a portion of any swap or cap transaction. Such early termination of a swap could result in a termination payment by or to the Fund. A termination payment by the Fund would result in a reduction in common share net earnings. An early termination of a cap could result in a termination payment to the Fund. 21 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. Market interest rates currently are at historically low levels. 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 dividend period other than 7 days in the case of Series M, TU, W, TH and F and other than 28 days in the case of Series A and B), 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 quoted on 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, The Bank of New York, 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 Fitch will assign a rating of "AAA" to the Preferred Shares and S&P will assign a rating of "AAA" to the Preferred Shares, such ratings do not eliminate or necessarily mitigate the risks of investing in Preferred Shares. Fitch or S&P 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 Fitch or S&P 22 downgrades the Preferred Shares, the Fund may alter its portfolio or redeem Preferred Shares in an 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," 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." See "Description of Preferred Shares -- Rating Agency Guidelines" 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 "U.S. Federal Income Tax Matters" below and 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 38% 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 addition to financial leverage, 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 senior securities representing indebtedness, to 300% of the aggregate value of such senior securities. Upon 23 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 38% 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. EQUITY SECURITIES. Equity investments are subject to greater fluctuations in market value than other asset classes as a result of such factors as the issuer's business performance, investor perceptions, stock market trends and general economic conditions. Equity securities are subordinated to bonds and other debt instruments in a company's capital structure in terms of priority to corporate income and liquidation payments. HIGH YIELD SECURITIES. The Fund may invest in high yield securities of any rating. Investment in high yield securities involves substantial risk of loss. Below investment grade non-convertible 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 24 - 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. 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. S&P 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 S&P 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, downturns 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 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. 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. There are fewer dealers in the market for high yield securities than for 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 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. 25 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; - 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; and - market interest rates currently are at historically low levels. DEFAULT RISK. Default risk refers to the risk that a company who issues a debt security will be unable to fulfill its obligations to repay principal and interest. The lower a debt security is rated, the greater its default risk. ILLIQUID INVESTMENTS. The Fund may invest up to 15% of its managed assets in securities that, at the time of investment, are illiquid (determined using the Commission's standard applicable to investment companies, i.e., securities that cannot be disposed of within 7 days in the ordinary course of business at approximately the value at which the Fund has valued the securities). The Fund may also 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. Calamos, under the supervision of the Board of Trustees, will determine whether securities purchased under Rule 144A are illiquid (that is, not readily marketable) and thus subject to the Fund's limit of investing no more than 15% of its managed assets in illiquid securities. Investments in Rule 144A Securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase these Rule 144A Securities. 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. Investment of the Fund's assets in illiquid securities may restrict the Fund's ability to take advantage of market opportunities. 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' 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; - the adverse effect of currency exchange rates or controls on the value of the Fund's investments; 26 - 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, including expropriation and nationalization; - the difficulty in obtaining or enforcing a court judgment in non-U.S. countries; - restrictions on foreign investments in non-U.S. jurisdictions; - difficulties in effecting the repatriation of capital invested in non-U.S. countries; 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 conditions 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 market 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 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. CONVERTIBLE SECURITIES. Convertible securities generally offer lower interest or dividend yields than non-convertible securities of similar quality. The market values of convertible securities tend to decline as interest rates increase and, conversely, to increase as interest rates decline. However, the convertible's market value tends to reflect the market price of the common stock of the issuing company when that stock price is greater than the convertible's "conversion price." The conversion price is defined as the predetermined price at which the convertible could be exchanged for the associated stock. As the market price of the underlying common stock declines, 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. In the event of a liquidation of the issuing company, holders of convertible securities would be paid before the company's common stockholders. Consequently, the issuer's convertible securities generally entail less risk than its common stock. SYNTHETIC CONVERTIBLE SECURITIES. The value of a synthetic convertible security may respond differently to market fluctuations than a convertible security because a synthetic convertible is composed of 27 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. INTEREST RATE TRANSACTIONS RISK. The Fund may enter into an interest rate swap or cap transaction to attempt to protect itself from increasing dividend or interest expenses on its preferred shares, debt securities or other borrowings resulting from increasing short-term interest rates. A decline in interest rates may result in a decline in the value of the swap or cap, which may result in a decline in the net asset value of the Fund. Depending on the state of interest rates in general, the Fund's use of interest rate swap or cap transactions could enhance or harm the overall performance of the common shares. To the extent there is a decline in interest rates, the value of the interest rate swap or cap could decline, and could result in a decline in the net asset value of the common shares. In addition, if the counterparty to an interest rate swap or cap defaults, the Fund would not be able to use the anticipated net receipts under the swap or cap to offset the dividend or interest payments on the Fund's leverage. Depending on whether the Fund would be entitled to receive net payments from the counterparty on the swap or cap, which in turn would depend on the general state of short-term interest rates at that point in time, such a default could negatively impact the performance of the common shares. In addition, at the time an interest rate swap or cap transaction reaches its scheduled termination date, there is a risk that the Fund would not be able to obtain a replacement transaction or that the terms of the replacement would not be as favorable as on the expiring transaction. If either of these events occurs, it could have a negative impact on the performance of the common shares. If the Fund fails to maintain a required 200% asset coverage of the liquidation value of the outstanding preferred shares or if the Fund loses its expected rating on its preferred shares or fails to maintain other covenants with respect to its preferred shares, the Fund may be required to redeem some or all of the preferred shares. Similarly, the Fund could be required to prepay the principal amount of any debt securities or other borrowings. Such redemption or prepayment would likely result in the Fund seeking to terminate early all or a portion of any swap or cap transaction. Early termination of a swap could result in a termination payment by or to the Fund. Early termination of a cap could result in a termination payment to the Fund. The Fund intends to maintain in a segregated account with its custodian cash or liquid securities having a value at least equal to the Fund's net payment obligations under any swap transaction, marked-to-market daily. TAX RISK. The Fund may invest in certain securities, such as certain convertible securities, for which the federal income tax treatment may not be clear or may be subject to recharacterization by the Internal Revenue Service. It could be more difficult for the Fund to comply with the tax requirements applicable to regulated investment companies if the tax characterization of the Fund's investments or the tax treatment of the income from such investments were successfully challenged by the Internal Revenue Service. See "U.S. Federal Income Tax Matters." 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 transactions with affiliates, converting the Fund to an open-end investment company or a merger, asset sale or similar transaction. Holders of preferred shares will have voting rights in addition to and separate from the voting rights of common shareholders with respect to certain of these matters. See "Description of Preferred Shares" and "Certain Provisions of the Agreement and Declaration of Trust and By-Laws." The 28 holders of preferred shares, on the one hand, and the holders of the common shares, on the other, may have interests that conflict in these situations. MARKET DISRUPTION RISK. Certain events have a disruptive effect on the securities markets, such as terrorist attacks (including the terrorist attacks in the United States on September 11, 2001), war and other geopolitical events, earthquakes, storms and other disasters. The Fund cannot predict the effects of similar events in the future on the U.S. economy or any foreign economy. 29 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. Currently, 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 March 31, 2004 Calamos managed approximately $29 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, 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 and Form N-CSR; (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 will pay 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 1.00% of managed assets. Because the fees paid to Calamos are determined 30 on the basis of the Fund's managed assets, Calamos' 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 shall assume and pay 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 shall 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, sub-custodians, 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. PORTFOLIO MANAGERS John P. Calamos, Nick P. Calamos and John P. Calamos, Jr. are responsible for managing the portfolio of the Fund. During the past five years, John P. Calamos has been a Chairman, CEO and Co-Chief Investment Officer of Calamos. Nick P. Calamos has been a Senior Executive Vice President and Co-Chief Investment Officer of Calamos. John P. Calamos, Jr. has been an Executive Vice President of Calamos. For over 20 years, the Calamos management team has managed money for their clients in convertible, high yield and global strategies. Furthermore, Calamos has extensive experience investing in foreign markets through its convertible securities and high yield securities strategies. Such experience has included investments in established as well as emerging foreign markets. FUND ACCOUNTANT Under the arrangements with State Street to provide fund accounting services, State Street provides certain administrative and accounting services to the Fund and such other funds advised by Calamos that may be part of those arrangements (the Fund and such other funds are collectively referred to as the "Calamos Funds") as described more fully in the statement of additional information. For the services rendered to the Calamos Funds, State Street receives fees based on the combined managed assets of the Calamos Funds ("Combined Assets"). Each fund of the Calamos Funds pays its pro-rata share of the fees payable to State Street described below based on relative managed assets of each fund. State Street receives a fee at the annual rate of 0.0225% for the first $3 billion of Combined Assets and 0.0150% for the Combined Assets in excess of $3 billion. 31 Calamos, rather than State Street, will provide the financial accounting services described more fully in the statement of additional information, to the Calamos Funds. For providing those services, Calamos will receive a fee at the annual rate of 0.0175% on the first $1 billion of Combined Assets; 0.0150% on the next $1 billion of Combined Assets; and 0.0110% on Combined Assets above $2 billion ("financial accounting service fee"). Each fund of the Calamos Funds will pay its pro-rata share of the financial accounting service fee to Calamos based on relative managed assets of each fund. 32 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. Where appropriate, terms used in "Description of Preferred Shares" and in "The Auction" below will have the same meanings as those terms in the Statement. GENERAL The Fund's Agreement and Declaration of Trust authorizes the issuance 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 7,040 Preferred Shares, Series M, 7,040 Preferred Shares, Series TU, 7,040 Preferred Shares, Series W, 7,040 Preferred Shares, Series TH, 7,040 Preferred Shares, Series F, 4,000 Preferred Shares, Series A, and 4,000 Preferred Shares, Series B. 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 DIVIDEND PERIODS The following is a general description of dividends and dividend periods for the Preferred Shares. DIVIDEND PERIODS. The initial dividend period and rate for each series of Preferred Shares is as set forth below: SERIES INITIAL DIVIDEND PERIOD INITIAL DIVIDEND RATE ------ ----------------------- --------------------- M............................................... 11 days 1.15% TU.............................................. 12 days 1.15 W............................................... 13 days 1.15 TH.............................................. 7 days 1.15 F............................................... 10 days 1.15 A............................................... 27 days 1.15 B............................................... 28 days 1.15 Any subsequent dividend periods of Series M, TU, W, TH and F of Preferred Shares will generally be seven or, in the case of Series A and B Preferred Shares, 28 days. The Fund, subject to certain conditions, may change the length of subsequent dividend periods by designating them as special dividend periods. See "--Designation of Special Dividend 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 33 Declaration of Trust, the Statement and applicable law. The initial dividend payment date and the day of the week upon which subsequent dividends, if any, will be paid for each series are as follows: INITIAL DIVIDEND SERIES PAYMENT DATE* SUBSEQUENT DIVIDEND PAYMENT DAY ------ ---------------- -------------------------------- M....................................... May 18 Tuesday TU...................................... May 19 Wednesday W....................................... May 20 Thursday TH...................................... May 14 Friday F....................................... May 17 Monday A....................................... June 3 Every fourth Thursday thereafter B....................................... June 4 Every fourth Friday thereafter --------------- *All dates are 2004. 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 dividend period of more than seven days in the case of Series M, T, W, TH, and F Preferred Shares and more than 28 days in the case of Series A and B Preferred Shares, provided that such dates shall be set forth in the notice of special dividend period relating to such special dividend 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 each series of Preferred Shares by multiplying the applicable rate in effect by a fraction. For each dividend period of less than one (1) year, the numerator of this fraction will normally be the number of days in the dividend period and the denominator will normally be 360. This rate is then multiplied by $25,000 to arrive at the dividends per share. For each dividend period of one (1) year or more, the dividends per share payable is computed as described above, except that it will be determined on the basis of a year consisting of twelve 30-day months. Dividends on Preferred Shares will accumulate from the date of their original issue, which is May 7, 2004. For each dividend payment period after the initial dividend 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 rate described below. Prior to each auction, Broker-Dealers will notify holders of the term of the next succeeding dividend period as soon as practicable after the Broker-Dealers have been so advised by the Fund. After each auction, on the auction date, Broker-Dealers will notify holders of the applicable rate for the next succeeding dividend period and as of the auction date of the next succeeding auction. Except during a Default Period as described below, the applicable rate resulting from an auction will not be greater than the maximum rate. The maximum rate will be the applicable percentage of the reference rate. The "Reference Rate" will be the applicable LIBOR Rate (as defined below) (for a dividend period of fewer than 365 days) or the Treasury Index Rate (as defined below) (for a dividend period of 365 days or more). The applicable percentage for any standard dividend period will generally be determined based on the credit ratings assigned to the Preferred Shares by Fitch and S&P on the auction 34 date for such period (as set forth in the table below). If Fitch and/or S&P shall not make such rating available, the rate shall be determined by reference to equivalent ratings issued by any other rating agency. FITCH AND/OR S&P CREDIT RATING APPLICABLE PERCENTAGE ------------------------------ --------------------- AA- or higher 150% A- to A+ 200% BBB- to BBB+ 250% Below BBB- 275% The "LIBOR Rate" is the applicable London Inter-Bank Offered Rate for deposits in U.S. dollars for the period most closely approximating the applicable dividend period for a series of Preferred Shares. The "Treasury Index Rate" is the average yield to maturity for certain U.S. Treasury securities having substantially the same length to maturity as the applicable dividend period for a series of Preferred Shares. The Board of Trustees may amend the maximum rate to increase the percentage amount by which the reference rate described above is multiplied to determine the maximum rate shown without the consent of the holders of Preferred Shares, including each series, or any shareholder of the Fund, but only with confirmation from each rating agency then rating the Preferred Shares that such action will not impair such agency's then-current rating of the Preferred Shares, 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 discussed below under "-- Rating Agency Guidelines." The maximum rate for the Preferred Shares will apply automatically following an auction for such Preferred Shares in which sufficient clearing bids have not been made (other than because all Preferred Shares were subject to submitted hold orders) or following the failure to hold an auction for any reason on the auction date scheduled to occur (except for circumstances in which the dividend rate is the Default Rate, as described below). Prior to each auction, Broker-Dealers will notify holders of the term of the next succeeding dividend period as soon as practicable after the Broker-Dealers have been so advised by the Fund. After each auction, on the auction date, Broker-Dealers will notify holders of the applicable rate for the next succeeding dividend period and of the auction date of the next succeeding auction. On 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 cancelation of any auction. The Fund does not intend to establish any reserves for the payment of dividends. DEFAULT PERIOD. Subject to the applicable cure provisions, a "Default Period" with respect to a particular series will commence on any date the Fund 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 applicable cure provisions, 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 described below, and each subsequent dividend period commencing after the beginning of a Default Period 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. 35 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 Fund) 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). 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 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) if, 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 common shares or rights to purchase common shares) 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 Fitch's coverage requirements, immediately after such transaction, the aggregate discounted 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 (as defined in the Prospectus under "Rating Agency Guidelines" below); 36 - In the case of S&P's coverage requirements, immediately after such transaction, the aggregate discounted value (i.e., the aggregate value of the Fund's portfolio discounted according to S&P 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 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 DIVIDEND PERIODS. The Fund may, in certain situations, declare a special dividend period. Prior to declaring a special dividend period, the Fund will give notice (a "notice of special dividend period") to the auction agent and to each Broker-Dealer. The notice of special dividend period will state that the next succeeding dividend period for the Preferred Shares will be a number of days as specified in such notice of special dividend period. The Fund may not designate a special dividend 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. In addition, the Fund does not intend to designate a special dividend period if such designation would adversely affect Fitch's or S&P's or any substitute rating 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 dividend period also will specify whether the Preferred Shares will be subject to optional redemption during such special dividend period and, if so, the redemption, premium, if any, required to be paid by the Fund in connection with such optional redemption. If the Fund 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 of special dividend period shall be (i) made by press release and (ii) communicated by the Fund by telephonic or other means to the auction agent and each Broker-Dealer and the rating agency and confirmed in writing promptly thereafter. Each such notice of special dividend period shall state (A) that the Fund proposes to exercise its option to designate a succeeding special dividend period, specifying the first and last days thereof and the maximum rate for such special dividend period and (B) that the Fund 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 37 any proposed special dividend period, the Fund shall deliver to the auction agent, who will promptly deliver to the Broker-Dealers and existing holders, either: (i) a notice of special dividend period stating (A) that the Fund 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 of special dividend period stating that the Fund has determined not to exercise its option to designate a special dividend period. If the Fund fails to deliver either such notice of special dividend period to the auction agent 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 Fund 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. In addition, the Board of Trustees may amend the dividend periods of one or more series of Preferred Shares on a permanent basis. 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 trustees 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 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 38 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, or arising in connection with any futures contracts or options thereon, interest rate swap or cap transactions, forward rate transactions, put or call options or other similar transactions, (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 for the redemption of those Preferred Shares were deposited. RATING AGENCY GUIDELINES The Fund is required under Fitch and S&P guidelines to maintain assets having in the aggregate a discounted value at least equal to the Preferred Shares Basic Maintenance Amount (as defined below). Fitch and S&P have each established separate guidelines for determining discounted value. To the extent 39 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 S&P guidelines also impose certain diversification requirements on the Fund's overall portfolio. The "Preferred Shares Basic Maintenance Amount" means as of any valuation date as the dollar amount equal to: (i) the sum of (A) the product of the number of Preferred Shares outstanding on such date multiplied by $25,000 (plus the product of the number of shares of any other series of preferred shares outstanding on such date multiplied by the liquidation preference of such shares), plus any redemption premium applicable to the Preferred Shares (or other preferred shares) then subject to redemption; (B) the aggregate amount of dividends that will have accumulated at the respective applicable rates (whether or not earned or declared) to (but not including) the first respective dividend payment dates for Preferred Shares outstanding that follow such valuation date (plus the aggregate amount of dividends, whether or not earned or declared, that will have accumulated in respect of other outstanding preferred shares to, but not including, the first respective dividend payment dates for such other shares that follow such valuation date); (C) the aggregate amount of dividends that would accumulate on shares of each series of Preferred Shares outstanding from such first respective dividend payment date therefor through the 42nd day after such valuation date, at the maximum rate (calculated as if such valuation date were the auction date for the dividend period commencing on such dividend payment date) for a standard dividend period of shares of such series to commence on such dividend payment date, assuming, solely for purposes of the foregoing, that if on such valuation date the Fund shall have delivered a notice of special dividend period to the auction agent pursuant to Section 4(b) of Part I of the Statement with respect to shares of such series, such maximum rate shall be the maximum rate for the special dividend period of shares of such series to commence on such dividend payment date (except that (1) if such valuation date occurs at a time when a failure to deposit (or, in the case of preferred shares other than Preferred Shares, a failure similar to a failure to deposit) has occurred that has not been cured, the dividend for purposes of calculation would accumulate at the current dividend rate then applicable to the shares in respect of which such failure has occurred and (2) for those days during the period described in this subparagraph (C) in respect of which the applicable rate in effect immediately prior to such dividend payment date will remain in effect (or, in the case of preferred shares other than Preferred Shares, in respect of which the dividend rate or rates in effect immediately prior to such respective dividend payment dates will remain in effect), the dividend for purposes of calculation would accumulate at such applicable rate (or other rate or rates, as the case may be in respect of those days); (D) the amount of anticipated expenses of the Fund for the 90 days subsequent to such valuation date; (E) the amount of any indebtedness or obligations of the Fund senior in right of payments to the Preferred Shares; and (F) any current liabilities as of such valuation date to the extent not reflected in any of (i)(A) through (i)(E) (including, without limitation, any payables for portfolio securities purchased as of such valuation date and any liabilities incurred for the purpose of clearing securities transactions) less (ii) the value (i.e., the face value of cash, short-term municipal obligations and short-term securities that are the direct obligation of the U.S. government, provided in each case that such securities mature on or prior to the date upon which any of (i)(A) though (i)(F) became payable, otherwise the S&P discounted value) of any of the Fund's assets irrevocably deposited by the Fund for the payment of any of (i)(A) through (i)(F). 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 S&P have agreed that the auditors must certify annually the asset coverage test on a date randomly selected by the auditors. Based on the Fund's assets and liabilities as of April 26, 2004, and assuming the issuance of all Preferred Shares offered hereby and the use of the proceeds as intended, 40 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 $3,267,465,041 ----------------------------------------------------------------------- = -------------- = 303% Senior securities representing indebtedness plus liquidation value of $1,080,000,000 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 S&P. 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 shareholder 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 or S&P, or both, as appropriate, that any such change would not impair the ratings then assigned by Fitch and S&P to the Preferred Shares. The Board of Trustees may amend the definition of standard dividend period to change the dividend period with respect to one or more series without the vote or consent of the holders of the Preferred Shares. As described by Fitch and S&P, 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 S&P 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. 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 S&P for rating the Preferred Shares. The Fund shall deliver to the auction agent and each rating agency a certificate which sets forth a determination regarding the Preferred Shares Basic Maintenance Amount (a "Preferred Shares Basic Maintenance Certificate") as of (A) within seven business days after 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 Fund'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, (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 and (G) weekly if S&P's eligible assets have an aggregate discounted value less than 1.30 times the Preferred Shares Basic Maintenance Amount. Such Preferred Shares Basic Maintenance Certificate shall be delivered in the case of (A) above on or before the seventh business day after the date of original issue and in the case of B-G above on or before the seventh business day after the relevant valuation date or asset coverage cure date. The Fund shall deliver to the auction agent and each rating agency a certificate which sets forth a determination regarding the 1940 Act Preferred Shares Asset Coverage (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 41 Asset Coverage Certificate shall be delivered in the case of clause (i) on or before the seventh business day after 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 the Statement may be combined into a single certificate. Within ten business days of the date of original issue, the Fund shall deliver to the Auction Agent and each Rating Agency a letter prepared by the Fund'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 or before the seventh business day after 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 year of the Fund, the Fund will deliver to the auction agent and each rating agency an Auditor's Certificate regarding the accuracy of the calculations made by the Fund in such certificates. In addition, the Fund will deliver to the persons specified in the preceding sentence an Auditor's Certificate regarding the accuracy of the calculations made by the Fund 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 Fund's independent auditors will be conclusive and binding on the Fund. 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, prorata among the Preferred Shares of the Fund and any other preferred shares 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 prorata, 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, on any business day 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 42 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 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. If, upon any such liquidation, dissolution or winding up of the affairs of the Fund, whether voluntary or involuntary, the assets of the Fund 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 Fund ranking junior to the Preferred Shares as to liquidation. 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, dissolution or winding up, 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 dividend period after the initial dividend 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, The Bank of New York) 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. 43 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 dividend 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 dividend 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 dividend 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 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 dividend 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 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 44 submitted to them by potential beneficial owners. However, neither the Fund nor the auction agent will be responsible for a Broker-Dealer's failure to comply with 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 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 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 dividend 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 dividend period will be the maximum rate on the auction date. However, if the Fund has declared a special dividend period and there are not sufficient clearing bids, the election of a special dividend period will not be effective and the applicable rate for the next dividend period will be the same as during the current dividend 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 dividend period following the auction will automatically be the same length as the preceding dividend period and the applicable rate for the next dividend period will be the all hold rate. The all hold rate is 80% of the applicable Reference Rate. The auction procedures include a prorata 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 prorata allocations among their respective customers. 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 M, TU, W, TH and F Preferred Shares will normally be held every seven days and the auctions for Series A and B Preferred Shares will normally be held every 28 days. Each subsequent dividend 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 applicable rate for the next dividend period will be the applicable rate determined on the previous auction date. 45 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 existing holders. The three existing holders and three potential holders submit orders through Broker-Dealers at the auction: Existing Holder A.......... Owns 500 shares, wants to Bid order of 4.1% rate for sell all 500 shares if 500 shares auction rate is less than 4.1% Existing Holder B.......... Owns 300 shares, wants to Hold order -- will take the hold auction rate Existing Holder C.......... Owns 200 shares, wants to Bid order of 3.9% rate for sell all 200 shares if 200 shares auction rate 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%. Existing holders B and C will continue to own their shares. Existing 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. 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 dividend 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. 46 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 Borrowings, 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. 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 Borrowings 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. 47 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 prorata 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 are listed on the New York Stock Exchange. U.S. FEDERAL INCOME 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 Internal Revenue Code of 1986, as amended (the "Code"), so that it will not pay U.S. federal income tax on income and capital gains timely 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 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 taxable income or "net capital gain" (i.e., 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 taxable income, net tax-exempt interest, and net capital gain. Under the Code, the Fund will generally be subject to a nondeductible 4% federal excise tax on the portion of its undistributed ordinary income and capital gains if it fails to meet certain distribution requirements with respect to each calendar year. The Fund intends to make distributions in a timely manner and accordingly does not expect to be subject to this excise tax. 48 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 in the same manner as an ordinary 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 such event, the Fund's distributions, to the extent derived from the Fund's current or accumulated earnings and profits, would generally constitute ordinary dividends, which would generally be eligible for the dividends received deduction available to corporate shareholders. Furthermore, individual and other noncorporate shareholders would generally be able to treat such distributions as "qualified dividend income" eligible for reduced rates of Federal income taxation in taxable years beginning on or before 2008. It is anticipated that Preferred Shares will constitute stock of the Fund, and thus distributions with respect to Preferred Shares (other than capital gain distributions and 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, if any, may qualify for the dividends received deduction available to corporations under Section 243 of the Code and the reduced rate of taxation that applies to "qualified dividend income" received by individual and other noncorporate shareholders under Section 1(h)(11) 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 ordinary income, capital gain distributions, dividends qualifying for the dividend's received deduction, if any, and "qualified dividend income," if any, 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 U.S. federal income 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 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 28% 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 49 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. Non-U.S. Shareholders of the Fund, including shareholders who, with respect to the United States, are nonresident alien individuals, may be subject to U.S. withholding tax on certain dividends and distributors at a rate of 30% or such lower rates as may be prescribed by an applicable treaty. 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. 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. These provisions, however, have the advantage of potentially requiring persons seeking control of the Fund to negotiate with its management regarding the price to be paid and facilitating the continuity of the Fund's investment objective and policies. The Board of Trustees of the Fund has considered these provisions and concluded that they are in the best interests 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 vote 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 outstanding 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. The Fund would be required to redeem all of its outstanding Preferred Shares prior to its conversion to an open-end investment company. 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 50 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. In addition, the Agreement and Declaration of Trust requires the affirmative vote or 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 outstanding, 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 shares 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 the purpose of such computation all assets sold, leased or exchanged in any series of similar transactions within a 12-month period. 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 Bank of New York is also the transfer agent, dividend paying agent and registrar for the Fund's common shares and the Preferred Shares. In addition, The Bank of New York is the auction agent with respect to Preferred Shares. 51 UNDERWRITING Citigroup Global Markets Inc. is acting as representative of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date hereof, 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 underwriters are obligated to purchase all the Preferred Shares if they purchase any of the Preferred Shares. The underwriters propose to 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 $137.50 per Preferred Share. The sales load the Fund will pay of $250 per Preferred Share is equal to 1.0% of the initial offering price. The underwriters may allow, and such dealers may reallow, a concession not in excess of $37.50 per Preferred Share on sales to certain other dealers. If all of the Preferred Shares are not sold at the initial offering price, the representatives may change the public offering price and other selling terms. Investors must pay for any Preferred Shares purchased on or before May 7, 2004. The Fund and Calamos have each agreed that, for a period of 180 days from the date of this prospectus, they will not, without the prior written consent of Citigroup Global Markets Inc. on behalf of the underwriters, sell, contract to sell, grant any options or warrants to purchase or otherwise dispose of, any senior securities (as defined in the 1940 Act) of the Fund other than the Preferred Shares, or any securities convertible into or exchangeable for senior securities other than the Preferred Shares. The Fund anticipates that from time to time the underwriters may act as brokers or dealers in connection with the execution of the Fund's portfolio transactions after they have ceased to be underwriters and, subject to certain restrictions, may act as brokers while they are underwriters. 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, subject to applicable law. A prospectus in electronic format may be available on the website maintained by one or more of the underwriters. The Fund anticipates that the underwriters or one of 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. Certain underwriters have performed investment banking and advisory services for Calamos and its affiliates from time to time, for which they have received customary fees and expenses. Certain underwriters may, from time to time, engage in transactions with or perform services for Calamos in the ordinary course of business. The underwriting agreement provides that it may be terminated in the absolute discretion of the representative, without liability on the part of any underwriter to the Fund or Calamos, by notice to the Fund or Calamos if, prior to the delivery of and payment for the Preferred Shares, (i) trading in the 52 Common Shares shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices for trading in securities generally shall have been established on such exchange, (ii) a banking moratorium shall have been declared by either federal or New York state authorities, or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets in the United States is such as to make it, in the representative's sole judgment, impracticable or inadvisable to proceed with the offering or delivery of the Preferred Shares as contemplated by this prospectus. The Fund and Calamos have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make because of any of those liabilities. Insofar as indemnification for liability arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Fund pursuant to the foregoing provisions, or otherwise, the Fund has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Fund of expenses incurred or paid by a director, officer or controlling person of the Fund in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Fund will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. The principal business address of Citigroup Global Markets Inc. is 388 Greenwich Street, New York, New York 10013. LEGAL OPINIONS Bell, Boyd & Lloyd LLC, Chicago, Illinois, serves as counsel to the Fund and to the non-interested Trustees. Vedder, Price, Kaufman & Kammholz, P.C. ("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 upon for the underwriters by Simpson Thacher & Bartlett LLP, New York, New York. Vedder Price and Simpson Thacher & Bartlett LLP may rely on the opinion of Morris, Nichols, Arsht & Tunnell, Wilmington, Delaware on certain matters of Delaware law. 53 AVAILABLE INFORMATION The Fund is subject to the informational requirements of the Securities Exchange Act of 1934 and the 1940 Act and is required to file reports, proxy statements and other information with the Securities and Exchange Commission.

S-1 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 and in the Prospectus. 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 or investment in illiquid securities). 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 primarily in common and preferred stock, convertible securities and income producing securities such as investment grade and below investment grade debt securities. The Fund, under normal circumstances, will invest at least 50% of its managed assets in equity securities (including securities that are convertible into equity securities). The Fund may invest up to 35% of its managed 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. The Fund may invest up to 15% of its managed assets in securities of foreign issuers in emerging markets. "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. Calamos will dynamically allocate the Fund's investments among multiple asset classes, seeking to obtain an appropriate balance of risk and reward through all market cycles using multiple strategies and combining them to seek to achieve favorable risk adjusted returns. Calamos analyzes securities for the Fund's portfolio using an approach that focuses on assessing a total enterprise value before assessing the value of the securities issued by a company. Calamos seeks to assess the value of an issuer's total enterprise by studying its financial statements, including its balance sheet. Once enterprise value is determined, Calamos seeks to assess the value of the issuer's different types of securities, taking into account the business risk of the issuer, its competitive position and the seniority of each type of security relative to the rest of the issuer's capital structure. This approach serves as the basis for the Calamos research team's design and use of proprietary models which, along with risk management and portfolio construction techniques, assist in determining whether a given security presents an investment opportunity for the Fund. EQUITY SECURITIES. Equity securities include common and preferred stocks, warrants, rights, and depository receipts. Under normal circumstances, the Fund will invest at least 50% of its managed assets in equity securities (including securities that are convertible into equity securities). An investment in the equity securities of a company represents a proportionate ownership interest in that company. Therefore, the Fund participates in the financial success or failure of any company in which it has a equity interest. Equity investments are subject to greater fluctuations in market value than other asset classes as a result of such factors as a company's business performance, investor perceptions, stock market trends and general economic conditions. Equity securities are subordinated to bonds and other debt instruments in a company's capital structure in terms of priority to corporate income and liquidation payments. Preferred stocks involve credit risk, which is the risk that a preferred stock in the Fund's portfolio will decline in price or fail to make dividend payments when due because the issuer of the security experiences a decline in its financial status. In addition to credit risk, investments in preferred stocks involve certain other risks. Certain preferred stocks contain provisions that allow an issuer under certain circumstances to skip distributions (in the case of "non-cumulative" preferred stocks) or defer distributions (in the case of "cumulative" preferred stocks). If the Fund owns a preferred stock that is deferring its distributions, the Fund may be required to report income for tax purposes while it is not S-2 receiving income from that stock. In certain varying circumstances, an issuer may redeem its preferred stock prior to a specified date in the event of certain tax or legal changes or at the issuer's call. In the event of a redemption, the Fund may not be able to reinvest the proceeds at comparable rates of return. Preferred stocks typically do not provide any voting rights, except incases when dividends are in arrears for a specified number of periods. Equity securities of small company and mid cap companies historically have been subject to greater investment risk than those of large companies. The risks generally associated with small and medium-sized companies include more limited product lines, markets and financial resources, lack of management depth or experience, dependency on key personnel and vulnerability to adverse market and economic developments. Accordingly, the prices of small and medium-sized company equity securities tend to be more volatile than prices of large company stocks. Further, the prices of small and medium-sized company equity securities are often adversely affected by limited trading volumes and the lack of publicly available information. HIGH YIELD 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. Non-convertible 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 non-convertible 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. 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. S-3 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. 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 S-4 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. 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 S-5 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 35% of its managed assets in securities of foreign issuers. The Fund may invest up to 15% of its managed assets in securities of foreign issuers in emerging markets. For these purposes, 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 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. (Seediscussion 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 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 S-6 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. S-7 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 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. S-8 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 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. 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 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. S-9 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. 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' 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. The Fund may purchase agreements, sometimes called cash puts, that may accompany the purchase of a new issue of bonds from a dealer. A put option gives the purchaser of the option, upon payment of a premium, the right to sell, and the writer the obligation to buy, the underlying security, commodity, index, currency or other instrument at the exercise price. For instance, the Fund's purchase of a put option on a security might be designed to protect its holdings in the underlying instrument (or, in some cases, a similar instrument) against a S-10 substantial decline in the market value by giving the Fund the right to sell such instrument at the option exercise price. A call option, upon payment of a premium, gives the purchaser of the option the right to buy, and the seller the obligation to sell, the underlying instrument at the exercise price. The Fund's purchase of a call option on a security, financial future, index, currency or other instrument might be intended to protect a fund against an increase in the price of the underlying instrument that it intends to purchase in the future by fixing the price at which it may purchase such instrument. The Fund is authorized to purchase and sell exchange listed options and over-the-counter options ("OTC options"). Exchange listed options are issued by a regulated intermediary such as the Options Clearing Corporation ("OCC"), which guarantees the performance of the obligations of the parties to such options. The discussion below uses the OCC as an example, but is also applicable to other financial intermediaries. With certain exceptions, OCC issued and exchange listed options generally settle by physical delivery of the underlying security or currency, although in the future cash settlement may become available. Index options and Eurodollar instruments are cash settled for the net amount, if any, by which the option is "in-the-money" (i.e., where the value of the underlying instrument exceeds, in the case of a call option, or is less than, in the case of a put option, the exercise price of the option) at the time the option is exercised. Frequently, rather than taking or making delivery of the underlying instrument through the process of exercising the option, listed options are closed by entering into offsetting purchase or sale transactions that do not result in ownership of the new option. OTC options are purchased from or sold to securities dealers, financial institutions or other parties ("Counterparties") through direct bilateral agreement with the Counterparty. In contrast to exchange listed options, which generally have standardized terms and performance mechanics, all the terms of an OTC option, including such terms as method of settlement, term, exercise price, premium, guarantees and security, are set by negotiation of the parties. The Fund may sell OTC options (other than OTC currency options) that are subject to a buy-back provision permitting the Fund to require the Counterparty to sell the option back to a fund at a formula price within seven days. The Fund expects generally to enter into OTC options that have cash settlement provisions, although it is not required to do so. The staff of the Commission currently takes the position that OTC options purchased by a fund, and portfolio securities "covering" the amount of a fund's obligation pursuant to an OTC option sold by it (or the amount of assets equal to the formula price for the repurchase of the option, if any, less the amount by which the option is in the money) are illiquid, and are subject to a fund's limitation on investing no more than 15% of its net assets in illiquid securities. The Fund may also purchase and sell options on securities indices and other financial indices. Options on securities indices and other financial indices are similar to options on a security or other instrument except that, rather than settling by physical delivery of the underlying instrument, they settle by cash settlement, i.e., an option or an index gives the holder the right to receive, upon exercise of the option, an amount of cash if the closing level of the index upon which the option is based exceeds, in the case of a call, or is less than, in the case of a put, the exercise price of the option (except if, in the case of an OTC option, physical delivery is specified). This amount of cash is equal to the excess of the closing price of the index over the exercise price of the option, which also may be multiplied by a formula value. The seller of the option is obligated, in return for the premium received, to make delivery of this amount. The gain or loss on an option on an index depends on price movements in the instruments making upon the market, market segment, industry or other composite on which the underlying index is based, rather than price movements in individual securities, as is the case with respect to options on securities. The Fund will write call options and put options only if they are "covered." For example, a call option written by the Fund will require the Fund to hold the securities subject to the call (or securities S-11 convertible into the needed securities without additional consideration) or to segregate cash or liquid assets sufficient to purchase and deliver the securities if the call is exercised. A call option sold by a fund on an index will require the Fund to own portfolio securities which correlate with the index or to segregate cash or liquid assets equal to the excess of the index value over the exercise price on a current basis. A put option written by the Fund requires the Fund to segregate cash or liquid assets equal to the exercise price. OTC options entered into by the Fund and OCC issued and exchange listed index options will generally provide for cash settlement. As a result, when the Fund sells these instruments it will only segregate an amount of cash or liquid assets equal to its accrued net obligations, as there is no requirement for payment or delivery of amounts in excess of the net amount. These amounts will equal 100% of the exercise price in the case of a non cash-settled put, the same as an OCC guaranteed listed option sold by the Fund, or the in-the-money amount plus any sell-back formula amount in the case of a cash-settled put or call. In addition, when the Fund sells a call option on an index at a time when the in- the-money amount exceeds the exercise price, the Fund will segregate, until the option expires or is closed out, cash or cash equivalents equal in value to such excess. OCC issued and exchange listed options sold by the Fund other than those above generally settle with physical delivery, or with an election of either physical delivery or cash settlement and the Fund will segregate an amount of cash or liquid assets equal to the full value of the option. OTC options settling with physical delivery, or with an election of either physical delivery or cash settlement, will be treated the same as other options settling with physical delivery. 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. 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. The ability of the Fund to utilize options successfully will depend on Calamos' ability to predict pertinent market investments, which cannot be assured. The Fund's ability to close out its position as a purchaser or seller of an OCC or exchange listed put or call option is dependent, in part, upon the liquidity of the option market. Among the possible S-12 reasons for the absence of a liquid option market on an exchange are: (i) insufficient trading interest in certain options; (ii) restrictions on transactions imposed by an exchange; (iii) trading halts, suspensions or other restrictions imposed with respect to particular classes or series of options or underlying securities including reaching daily price limits; (iv) interruption of the normal operations of the OCC or an exchange; (v) inadequacy of the facilities of an exchange or OCC to handle current trading volume; or (vi) a decision by one or more exchanges to discontinue the trading of options (or a particular class or series of options), in which event the relevant market for that option on that exchange would cease to exist, although outstanding options on that exchange would generally continue to be exercisable in accordance with their terms. 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. The hours of trading for listed options may not coincide with the hours during which the underlying financial instruments are traded. To the extent that the option markets close before the markets for the underlying financial instruments, significant price and rate movements can take place in the underlying markets that cannot be reflected in the option markets. Unless the parties provide for it, there is no central clearing or guaranty function in an OTC option. As a result, if the Counterparty (as described above under "Options on Securities, Indexes and Currencies") fails to make or take delivery of the security, currency or other instrument underlying an OTC option it has entered into with a fund or fails to make a cash settlement payment due in accordance with the terms of that option, a fund will lose any premium it paid for the option as well as any anticipated benefit of the transaction. Accordingly, Calamos must assess the creditworthiness of each such Counterparty or any guarantor or credit enhancement of the Counterparty's credit to determine the likelihood that the terms of the OTC option will be satisfied. The Fund will engage in OTC option transactions only with U.S. government securities dealers recognized by the Federal Reserve Bank of New York as "primary dealers" or broker/dealers, domestic or foreign banks or other financial institutions which have received (or the guarantors of the obligation of which have received) a short-term credit rating of A-1 from S&P or P-1 from Moody's or an equivalent rating from any nationally recognized statistical rating organization ("NRSRO") or, in the case of OTC currency transactions, are determined to be of equivalent credit quality by Calamos. The Fund may purchase and sell call options on securities indices and currencies. All calls sold by the Fund must be "covered." Even though the Fund will receive the option premium to help protect it against loss, a call sold by the Fund exposes the Fund during the term of the option to possible loss of opportunity to realize appreciation in the market price of the underlying security or instrument and may require a fund to hold a security or instrument which it might otherwise have sold. The Fund may purchase and sell put options on securities indices and currencies. In selling put options, there is a risk that the Fund may be required to buy the underlying security at a disadvantageous price above the market price. 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 S-13 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 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 ------------------------- (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-14 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 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. S-15 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. The Fund has claimed an exclusion from registration as a commodity pool under the Commodity Exchange Act ("CEA") and, therefore, the Fund and its officers and trustees are not subject to the registration requirements of the CEA. The Fund reserves the right to engage in transactions involving futures and options thereon to the extent allowed by Commodity Future Trading Commission ("CFTC") regulations in effect from time to time and in accordance with the Fund's policies. 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 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 S-16 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 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 of 1986, as amended (the "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." S-17 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. INTEREST RATE TRANSACTIONS. In order to seek to reduce the interest rate rise inherent in the Fund's underlying investments and capital structure, the Fund, if market conditions are deemed favorable, likely will enter into interest rate swap or cap transactions. Interest rate swaps involve the Fund's agreement with the swap counterparty to pay a fixed rate payment in exchange for the counterparty agreeing to pay the Fund a payment at a variable rate that is expected to approximate the rate on any variable rate payment obligation on the Fund's leverage. The payment obligations would be based on the notional amount of the swap. The Fund may use an interest rate cap, which would require it to pay a premium to the cap counterparty and would entitle it, to the extent that a specified variable rate index exceeds a predetermined fixed rate, to receive from the counterparty payment of the difference based on the notional amount. The Fund would use interest rate swaps or caps only with the intent to reduce or eliminate the risk that an increase in short-term interest rates could have on common share net earnings as a result of leverage. The Fund will usually enter into swaps or caps on a net basis; that is, the two payment streams will be netted out in a cash settlement on the payment date or dates specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. The Fund intends to maintain in a segregated account with its custodian cash or liquid securities having a value at least equal to the Fund's net payment obligations under any swap transaction, marked-to-market daily. The use of interest rate swaps and caps is a highly specialized activity that involves investment techniques and risks different from those associated with ordinary portfolio security transactions. Depending on the state of interest rates in general, the Fund's use of interest rate swaps or caps could enhance or harm the overall performance on the common shares. To the extent there is a decline in interest rates, the value of the interest rate swap or cap could decline, and could result in a decline in the net asset value of the common shares. In addition, if short-term interest rates are lower than the Fund's fixed rate of payment on the interest rate swap, the swap will reduce common share net earnings. If, on the other hand, short-term interest rates are higher than the fixed rate of payment on the interest rate swap, the swap will enhance common share net earnings. Buying interest rate caps could enhance the performance of the common shares by providing a maximum leverage expense. Buying interest rate caps could also decrease the net earnings of the common shares in the event that the premium paid by the Fund to the counterparty exceeds the additional amount the Fund would have been required to pay had it not entered into the cap agreement. The Fund has no current intention of selling an interest rate swap or cap. Interest rate swaps and caps do not involve the delivery of securities or other underlying assets or principal. Accordingly, the risk of loss with respect to interest rate swaps is limited to the net amount of interest payments that the Fund is contractually obligated to make. If the counterparty defaults, the Fund would not be able to use the anticipated net receipts under the swap or cap to offset the dividend or interest payments on the Fund's leverage. Depending on whether the Fund would be entitled to receive net payments from the counterparty on the swap or cap, which in turn would depend on the general state of short-term interest rates at that point in time, such a default could negatively impact the performance of the common shares. Although this will not guarantee that the counterparty does not default, the Fund will not enter into an interest rate swap or cap transaction with any counter-party that Calamos believes does not have the financial resources to honor its obligation under the interest rate swap or cap transaction. Further, S-18 Calamos will continually monitor the financial stability of a counterparty to an interest rate swap or cap transaction in an effort to proactively protect the Fund's investments. In addition, at the time the interest rate swap or cap transaction reaches its scheduled termination date, there is a risk that the Fund would not be able to obtain a replacement transaction or that the terms of the replacement would not be as favorable as on the expiring transaction. If this occurs, it could have a negative impact on the performance of the Fund's common shares. The Fund may choose or be required to redeem some or all of the preferred shares or prepay any borrowings. This redemption would likely result in the Fund seeking to terminate early all or a portion of any swap or cap transaction. Such early termination of a swap could result in termination payment by or to the Fund. An early termination of a cap could result in a termination payment to the Fund. SWAPS, CAPS, FLOORS AND COLLARS. The Fund may enter into interest rate, currency, index and other swaps and the purchase or sale of related caps, floors and collars. The Fund expects to enter into these transactions primarily to preserve a return or spread on a particular investment or portion of its portfolio, to protect against currency fluctuations, as a duration management technique or to protect against any increase in the price of securities the Fund anticipates purchasing at a later date. The Fund will not sell interest rate caps or floors where it does not own securities or other instruments providing the income stream the Fund may be obligated to pay. Interest rate swaps involve the exchange by the Fund with another party of their respective commitments to pay or receive interest, e.g., an exchange of floating rate payments for fixed rate payments with respect to a notional amount of principal. A currency swap is an agreement to exchange cash flows on a notional amount of two or more currencies based on the relative value differential among them and an index swap is an agreement to swap cash flows on a notional amount based on changes in the values of the reference indices. The purchase of a cap entitles the purchaser to receive payments on a notional principal amount from the party selling such cap to the extent that a specified index exceeds a predetermined interest rate or amount. The purchase of a floor entitles the purchaser to receive payments on a notional principal amount from the party selling such floor to the extent that a specified index falls below a predetermined interest rate or amount. A collar is a combination of a cap and a floor that preserves a certain return within a predetermined range of interest rates or values. The Fund will usually enter into swaps on a net basis, i.e., the two payment streams are netted out in a cash settlement on the payment date or dates specified in the instrument, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. Inasmuch as the Fund will segregate assets (or enter into offsetting positions) to cover its obligations under swaps, Calamos and the Fund believe such obligations do not constitute senior securities under the Investment Company Act of 1940 (the "1940 Act") and, accordingly, will not treat them as being subject to its borrowing restrictions. The Fund will not enter into any swap, cap, floor or collar transaction unless, at the time of entering into such transaction, the unsecured long-term debt of the Counterparty, combined with any credit enhancements, is rated at least A by S&P or Moody's or has an equivalent rating from a NRSRO or is determined to be of equivalent credit quality by Calamos. If there is a default by the Counterparty, the Fund may have contractual remedies pursuant to the agreements related to the transaction. The swap market has grown substantially in recent years with a large number of banks and investment banking firms acting both as principals and as agents utilizing standardized swap documentation. As a result, the swap market has become relatively liquid, however, some swaps may be considered illiquid. Caps, floors and collars are more recent innovations for which standardized documentation has not yet been fully developed and, accordingly, they are less liquid than swaps. STRUCTURED PRODUCTS. The Fund may invest in interests in entities organized and operated for the purpose of restructuring the investment characteristics of certain other investments. This type of restructuring involves the deposit with or purchase by an entity, such as a corporation or trust, of specified instruments and the issuance by that entity of one or more classes of securities ("structured products") backed by, or representing interests in, the underlying instruments. The term "structured products" as used herein excludes synthetic convertibles and interest rate transactions. See "Investment Objective and Policies -- Synthetic Convertible Securities and Interest Rate Transactions". The cash flow on the underlying instruments may be apportioned among the newly issued structured products to create securities with different investment characteristics such as varying maturities, payment priorities and interest rate provisions, and the extent of the payments made with respect to structured products is dependent on the extent of the cash flow on the underlying instruments. The Fund may invest in structured products, which represent derived investment positions based on relationships among different markets or asset classes. The Fund may also invest in other types of structured products, including, among others, baskets of credit default swaps referencing a portfolio of high-yield securities. A structured product may be considered to be leveraged to the extent its interest rate varies by a magnitude that exceeds the magnitude of the change in the index rate. Because they are linked to their underlying markets or securities, investments in structured products generally are subject to greater volatility than an investment directly in the underlying market or security. Total return on the structured product is derived by linking return to one or more characteristics of the underlying instrument. Because certain structured products of the type in which the Fund may invest may involve no credit enhancement, the credit risk of those structured products generally would be equivalent to that of the underlying instruments. The Fund may invest in a class of structured products that is either subordinated or unsubordinated to the right of payment of another class. Subordinated structured products typically have higher yields and present greater risks than unsubordinated structured products. Although the Fund's purchase of subordinated structured products would have similar economic effect to that of borrowing against the underlying securities, the purchase will not be deemed to be leverage for purposes of the Fund's limitations related to borrowing and leverage. Certain issuers of structured products may be deemed to be "investment companies" as defined in the 1940 Act. As a result, the Fund's investments in these structured products may be limited by the restrictions contained in the 1940 Act. Structured products are typically sold in private placement transactions, and there currently may not be an active trading market for structured products. As a result, certain structured products in which the Fund invests may be deemed illiquid and subject to its limitation on illiquid investments. S-19 "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 up to 15% of its managed assets in securities that, at the time of investment, are illiquid (determined using the Commission's standard applicable to investment companies, i.e., securities that cannot be disposed of within 7 days in the ordinary course of business at approximately the value at which the Fund has valued the 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. Calamos, under the supervision of the Board of Trustees, will determine whether securities purchased under Rule 144A are illiquid (that is, not readily marketable) and thus subject to the Fund's limit on investing no more than 15% of its managed assets in illiquid securities. Investments in Rule 144A Securities could have the effect of increasing the amount of the Fund's assets invested in illiquid securities if qualified institutional buyers are unwilling to purchase these Rule 144A Securities. 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' 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. S-20 The Fund may invest 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 DEFENSIVE 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" 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. 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 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 S-21 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 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. 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 Commission thereunder. S-22 (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 Commission 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 Commission 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 Commission 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. Currently under the 1940 Act, the Fund is not permitted to issue preferred shares unless immediately after such issuance the net asset value of the Fund's portfolio is at least 200% of the liquidation value of the outstanding preferred shares (i.e., such liquidation value may not exceed 50% of the value of the Fund's total assets). In addition, currently under the 1940 Act, the Fund is not permitted to declare any cash dividend or other distribution on its common shares unless, at the time of such declaration, the net asset value of the Fund's portfolio (determined after deducting the amount of such dividend or distribution) is at least 200% of such liquidation value. Currently under the 1940 Act, the Fund is not permitted to incur indebtedness unless immediately after such borrowing the Fund has asset coverage of at least 300% of the aggregate outstanding principal balance of indebtedness (i.e., such indebtedness may not exceed 33 1/3% of the value of the Fund's total assets). Additionally, currently under the 1940 Act, the Fund may not declare any dividend or other distribution upon any class of its shares, or purchase any such shares, unless the aggregate indebtedness of the Fund has, at the time of the declaration of any such dividend or distribution or at the time of any such purchase, an asset coverage of at least 300% after deducting the amount of such dividend, distribution, or purchase price, as the case may be. Currently under the 1940 Act, the Fund is not permitted to lend money or property to any person, directly or indirectly, if such person controls or is under common control with the Fund, except for a loan from the Fund to a company which owns all of the outstanding securities of the Fund, except directors' qualifying shares. Currently, under interpretive positions of the SEC, the Fund may not have on loan at any time Securities representing more than one-third of its total assets. Currently under the 1940 Act, a "senior security" does not include any promissory note or evidence of indebtedness where such loan is for temporary purposes only and in an amount not exceeding 5% of the value of the total assets of the issuer at the time the loan is made. A loan is presumed to be for temporary purposes if it is repaid within sixty days and is not extended or renewed. S-23 Currently, the Fund would be deemed to "concentrate" in a particular industry if it invested 25% or more of its total assets in that industry. Currently under the 1940 Act, a "diversified company" means a management company which meets the following requirements: at least 75% of the value of its total assets is represented by cash and cash items (including receivables), government securities, securities of other investment companies, and other securities for the purposes of this calculation limited in respect of any one issuer to an amount not greater in value than 5% of the value of the total assets of such management company and not more than 10% of the outstanding voting securities of such issuer. 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 "Risk Factors," the net asset value and market value of leveraged shares will be 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 38% of the Fund's total assets.

Each officer serves until his or her successor is chosen and qualified or until his or her resignation or removal by the Board of Trustees. S-26 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. Hanauer, Neal, Rybak and Timbers each a non-interested Trustee, serve on the Audit Committee. The Audit Committee approves the selection of the independent auditors to the Trustees, approves services to be rendered by the auditors, monitors the auditors' performance, reviews the results of the Fund's audit, determines whether to recommend to the Board that the Fund's audited financial statements be included in the Fund's annual report and responds to other matters deemed appropriate by the Board of Trustees. Governance Committee. Messrs. Hanauer, Neal, Rybak and Timbers, each a non-interested Trustee, 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 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. In addition to the above committees, there is a Board of Trustee directed pricing committee comprised of officers of the Fund and employees of Calamos. 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 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. The following table sets forth certain information with respect to the compensation paid to each Trustee by the Fund and the Calamos Fund Complex as a group. Compensation from the Fund is for the current calendar year and is estimated. Total compensation from the Calamos Fund Complex as a group is for the calendar year ended December 31, 2003.

Deferred amounts are treated as though such amounts have been invested and reinvested in shares of S-27 one or more of the Calamos Funds selected by the trustee. As of December 31, 2003, the values of Mr. Neal's deferred compensation accounts was $102,377. (2) Mr. Dowen resigned effective January 1, 2004. * The Calamos Fund Complex consists of five investment companies and each applicable series thereunder including the Fund, Calamos Investment Trust, Calamos Advisors Trust, Calamos Convertible Opportunities and Income Fund and Calamos Convertible and High Income Fund. The Fund has adopted a deferred compensation plan (the "Plan"). Under the Plan, a Trustee who is not an "interested person" of Calamos and who has elected to participate in the Plan ("participating Trustees") may defer receipt of all or a portion of his compensation from Fund in order to defer payment of income taxes or for other reasons. The deferred compensation payable to the participating Trustee is credited to Trustee's deferral account as of the business day such compensation would have been paid to the Trustee. The value of a Trustee's deferred compensation account at any time is equal to what would be the value if the amounts credited to the account had instead been invested in shares of one or more of the portfolios of Calamos Investment Trust as designated by the Trustee. Thus, the value of the account increases with contributions to the account or with increases in the value of the measuring shares, and the value of the account decreases with withdrawals from the account or with declines in the value of the measuring shares. If a participating trustee retires, the Trustee may elect to receive payments under the plan in a lump sum or in equal installments over a period of five years. If a participating Trustee dies, any amount payable under the Plan will be paid to the Trustee's beneficiaries. OWNERSHIP OF SHARES OF THE FUND AND OTHER CALAMOS FUNDS. The following table indicates the value of shares that each Trustee beneficially owns in the Fund and the Calamos Fund Complex in the aggregate. The value of shares of the Calamos Funds is determined on the basis of the net asset value of the class of shares held as of December 31, 2003. The value of the shares held are stated in ranges in accordance with the requirements of the Commission. The table reflects the Trustee's beneficial ownership of shares of the Calamos Fund Complex. Beneficial ownership is determined in accordance with the rules of the Commission.

None CODE OF ETHICS. The Fund and Calamos have adopted a code of ethics under Rule 17j-1 of the 1940 Act which is applicable to officers, directors/Trustees and designated employees of Calamos and CFS. Employees of Calamos and CFS are permitted to make 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 transactions may not be made in certain securities, and requires the submission of duplicate broker confirmations and statements and quarterly reporting of securities transactions. Additional restrictions apply to portfolio managers, traders, research analysts and S-28 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. Text-only versions of the code of ethics can be viewed online or downloaded from the EDGAR Database on the Commission's internet web site at www.sec.gov. You may review and copy the code of ethics by visiting the Commission's Public Reference Room in Washington, D.C. Information on the operation of the Public Reference Room may be obtained by calling the Commission at 202-942-8090. In addition, copies of the code of ethics may be obtained, after mailing the appropriate duplicating fee, by writing to the Commission's Public Reference Section, 450 5th Street, N.W., Washington, DC 20549-0102 or by e-mail request at publicinfo@sec.gov. PROXY VOTING PROCEDURES. The Fund has delegated proxy voting responsibilities to Calamos, subject to the Board of Trustees' general oversight. The Fund expects Calamos to vote proxies related to the Fund's portfolio securities for which the Fund has voting authority consistent with the Fund's best economic interests. Calamos has adopted its own Proxy Voting Policies and Procedures ("Policies"). The Policies address, among other things, conflicts of interest that may arise between the interests of the Fund, and the interests of the adviser and its affiliates. The following is a summary of the Policies used by Calamos in voting proxies. To assist it in voting proxies, Calamos has established a Committee comprised of members of its Portfolio Management and Research Departments. The Committee and/or its members will vote proxies using the following guidelines. In general, if Calamos believes that a company's management and board have interests sufficiently aligned with the Fund's interest, Calamos will vote in favor of proposals recommended by a company's board. More specifically, Calamos seeks to ensure that the board of directors of a company is sufficiently aligned with security holders' interests and provides proper oversight of the company's management. In many cases this may be best accomplished by having a majority of independent board members. Although Calamos will examine board member elections on a case-by-case basis, it will generally vote for the election of directors that would result in a board comprised of a majority of independent directors. Because of the enormous variety and complexity of transactions that are presented to shareholders, such as mergers, acquisitions, reincorporations, adoptions of anti-take over measures (including adoption of a shareholder rights plan, requiring supermajority voting on particular issues, adoption of fair price provisions, issuance of blank check preferred stocks and the creation of a separate class of stock with unequal voting rights), changes to capital structures (including authorizing additional shares, repurchasing stock or approving a stock split), executive compensation and option plans, that occur in a variety of industries, companies and market cycles, it is extremely difficult to foresee exactly what would be in the best interests of the Fund in all circumstances. Moreover, voting on such proposals involves considerations unique to each transaction. Accordingly, Calamos will vote on a case-by-case basis on proposals presenting these transactions. Finally Calamos has established procedures to help resolve conflicts of interests that might arise when voting proxies for the Fund. These procedures provide that the Committee, along with Calamos' Legal and Compliance Departments, will examine conflicts of interests with the Fund of which Calamos is aware and seek to resolve such conflicts in the best interests of the Fund, irrespective of any such conflict. If a member of the Committee has a personal conflict of interest, that member will refrain from voting and the remainder of the Committee will determine how to vote the proxy solely on the investment merits of any proposal. The Committee will then memorialize the conflict and the procedures used to address the conflict. You may obtain a copy of Calamos' Policies by calling (800) 582-6959, by visiting the Fund's website at www.calamos.com, by writing Calamos at: Calamos Investments, Attn: Client Services, 1111 East Warrenville Road, Naperville, IL 60563, and on the Commission's website at www.sec.gov. INVESTMENT ADVISER AND INVESTMENT MANAGEMENT AGREEMENT. Subject to the overall authority of the board of trustees, Calamos 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: (i) preparing or assisting in the preparation of reports to and meeting materials for the Trustees; (ii) 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; (iii) 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 and Form N-CSR; (iv) overseeing the tabulation of proxies by the Fund's transfer agent; (v) assisting in the preparation and filing of the Fund's federal, state and local tax returns; (vi) assisting in the preparation and filing of the Fund's federal excise tax return pursuant to Section 4982 of the Code; (vii) providing assistance with investor and public relations matters; (viii) monitoring the valuation of portfolio securities and the calculation of net asset value; (ix) monitoring the registration of shares of beneficial interest of the Fund under applicable federal and state securities laws; (x) 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; (xi) assisting in establishing the accounting policies of the Fund; (xii) 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; (xiii) reviewing the Fund's bills; (xiv) 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 (xv) 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 1.00% of managed assets. Because the fees paid to Calamos are determined on the basis of the Fund's managed assets, Calamos' interest in determining whether to leverage the Fund may differ from the interests of the Fund. Under the terms of its investment management agreement with the Fund, except for the services and facilities provided by Calamos as set forth therein, the Fund shall assume and pay 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 shall include, without limitation: (a) organization expenses of the Fund (including out-of-pocket expenses, but not including the Manager's 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 S-29 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. Unless earlier terminated as described below, the investment management agreement will remain in effect until August 1, 2005. The investment management agreement continues in effect from year to year 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 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 may be continued annually beyond its initial term both by the Board of Trustees and by 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 reviewed materials furnished by Calamos, including information regarding Calamos, its affiliates and their personnel, operations and financial condition. The Independent Trustees discussed with representatives of Calamos the Fund's operations and Calamos' 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; and S-30 - the experience of the investment advisory and other personnel providing services to the Fund and the historical quality of the services provided by Calamos. The independent trustees considered the following as relevant to their recommendations: (1) the favorable history, reputation, qualification, investment process and background of Calamos, as well as the qualifications of its personnel, resources available and its financial condition; (2) the magnitude of Calamos' fees and the estimated expense ratio of the Fund in relation to the nature and quality of services expected to be provided and the fees and expense ratios of comparable 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 independent trustees deemed each of these factors to be relevant to their consideration of the Agreement, and concluded that the terms of the Agreement and the services to be provided were reasonable and appropriate, and that the Agreement was in the best interests of the Funds. 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. Under the arrangements with State Street Bank and Trust Company ("State Street") to provide fund accounting services, State Street provides certain administrative and accounting services including providing daily reconciliation of cash, trades and positions; maintaining general ledger and capital stock accounts; preparing daily trial balance; calculating net asset value; providing selected general ledger reports; preferred share compliance; calculating total returns; and providing monthly distribution analysis to the Fund and such other funds advised by Calamos that may be part of those arrangements (the Fund and such other funds are collectively referred to as the "Calamos Funds") as described more fully in the statement of additional information. For the services rendered to the Calamos Funds, State Street receives fees based on the combined managed assets of the Calamos Funds ("Combined Assets"). Each fund of the Calamos Funds pays its pro-rata share of the fees payable to State Street described below based on relative managed assets of each fund. FUND ACCOUNTANT. Calamos will provide the following financial accounting services to Calamos Funds, rather than State Street: management of expenses and expense payment processing; monitor the calculation of expense accrual amounts for any fund and make any necessary modifications; coordinate any expense reimbursement calculations and payment; calculate yields on the funds in accordance with rules and regulations of the Commission; calculate net investment income dividends and capital gains distributions; calculate track and report tax adjustments on all assets of each fund, including but not limited to contingent debt and preferred trust obligations; prepare excise tax and fiscal year distributions schedules; prepare tax information required for financial statement footnotes; prepare state and federal income tax returns; prepare specialized calculations of amortization on convertible securities; prepare year-end dividend disclosure information; monitor trustee deferred compensation plan accruals and valuations; and prepare Form 1099 information statements for Board members and service providers. For providing those financial accounting services, will receive a fee payable monthly at the annual rate of 0.0175% on the first $1 billion of Combined Assets; 0.0150% on the next $1 billion of Combined Assets; and 0.0110% on Combined Assets above $2 billion ("financial accounting service fee"). Each fund of the Calamos Funds will pay its pro-rata share of the financial accounting service fee payable to Calamos based on relative managed assets of each fund. State Street receives a fee at the annual rate of 0.0225% for the first $3 billion of Combined Assets and 0.0150% for the Combined Assets in excess of $3 billion. 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. S-31 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 ("Exchange 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 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 are valued at the last current reported sale price as of the time of valuation. Securities quoted on the NASDAQ National Market System are valued at the Nasdaq Official Closing Price ("NOCP"), as determined by S-32 Nasdaq, or lacking an NOCP, at the last current reported sale price as of the time of valuation. 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, subject to the Board of Trustees responsibility for any such valuation. 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 Trustees, 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 "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 S-33 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 other transactions permitted under the 1940 Act, the making of a tender offer for such shares, or the conversion of 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 S-34 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 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. S-35 U.S. FEDERAL INCOME 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 Internal Revenue Code of 1986, as amended (the "Code"), so that it will not pay U.S. federal income tax on investment company taxable income and net capital gains timely 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, 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 taxable income or "net capital gain" (i.e., the excess of net long-term capital gain over the sum of net short-term capital loss and any capital loss carryforward), 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 taxable 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 in the same manner as an ordinary 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 such event, the Fund's distributions, to the extent derived from the Fund's current or accumulated earnings and profits, would generally constitute ordinary dividends, which would generally be eligible for the dividends received deduction available to corporate shareholders. Furthermore, individual and other noncorporate shareholders would generally be able to treat such distributions as "qualified income" eligible for reduced rates of federal income taxation in taxable years beginning on or before 2008. 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 taxable 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. S-36 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 total 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. 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, after the adjusted basis is reduced to zero, will be treated as capital gain to a holder of Preferred Shares that holds such shares as a capital asset. 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, except as discussed below, taxable as ordinary income to the extent of the Fund's current and accumulated earnings and profits. A portion of such dividends may qualify for the dividends received deduction available to corporations under Section 243 of the Code and the reduced rate of taxation that applies to "qualified dividend income" received by individual and other noncorporate shareholders under Section 1(h)(ll) of the Code. For taxable years beginning on or before December 31, 2008, qualified dividend income received by individual and other noncorporate shareholders is taxed at rates equivalent to long-term capital gains, which reach a maximum of 15%. Qualified dividend income generally includes dividends from domestic corporations and dividends from foreign corporations that meet certain specified criteria, although dividends paid by REITs will not generally be eligible to qualify as qualified dividend income. The Fund generally can pass the tax treatment of qualified dividend income it receives through to Fund shareholders. For the Fund to receive qualified dividend income, the Fund must meet certain holding period requirements for the stock on which the otherwise qualified dividend is paid. In addition, the Fund cannot be obligated to make payments (pursuant to a short sale or otherwise) with respect to substantially similar or related property. The same provisions, including the holding period requirements, apply to each shareholder's investment in the Fund. The provisions of the Code applicable to qualified dividend income and the 15% maximum individual tax rate on long-term capital gains are currently effective through 2008. Thereafter, qualified dividend income will no longer be taxed at the rates applicable to long-term capital gains, and the maximum individual tax rate on long-term capital gains will increase to 20%, unless Congress enacts legislation providing otherwise. Distributors of net capital gain, 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. 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. S-37 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 taxes. If the Fund utilizes leverage through Borrowings, or otherwise, 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 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 investment company taxable income as is required under the Code and therefore might jeopardize the Fund's qualification for the reduced rates of taxation available to 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 investment 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 S-38 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. The Fund's income will consist of investment company taxable 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 IRS 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 (e.g., 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, qualified dividend income, and/or dividends eligible for the dividends received deduction, such dividends will be paid in proportion to the Preferred Shares proportionate share of the total distributions paid on the Preferred Shares during the year to the total distributions paid on both the Preferred 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 investment company taxable income are, except in the case of qualified dividend income, 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 investment company taxable 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 IRS 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. S-39 Sales and other dispositions of the Preferred Shares are taxable events for shareholders that are subject to U.S. 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 "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 may qualify for the dividends received deduction available to corporate shareholders, subject to certain holding period and other requirements, but generally only to the extent the Fund earned dividend income from stock investments in U.S. domestic corporations (other than REITs). In addition, certain distributions of "qualified dividend income" (as discussed above) will currently qualify for reduced rates of federal income taxation if certain holding period and other requirements under the Code are satisfied by both the Fund and such shareholder. Distributions from REITs generally will not qualify for treatment as "qualified dividend income." The Fund may invest in REITs that hold residual interests in real estate mortgage investment conduits ("REMICs"). Under Treasury regulations that have not yet been issued, but may apply retroactively, 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 are also expected to provide that excess inclusion income of a regulated investment company, such as the Fund, will be allocated to shareholders S-40 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 prorata 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. Under Treasury regulations, if a shareholder recognizes a loss with respect to shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder in any single taxable year (or a greater loss over a combination of years), the shareholder must file with the IRS a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but under current guidance, shareholders of a regulated investment company are not excepted. Future guidance may extend the current exception from this reporting requirement to shareholders of most or all regulated investment companies. The fact that a loss is reportable under these regulations does not affect the legal determination of whether the taxpayer's treatment of the loss is proper. Shareholders should consult their tax advisors to determine the applicability of these regulations in light of their individual circumstances. Federal law requires that the Fund withhold, as "backup withholding" 28% 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 requirements. 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, trusts 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 individual. With respect to such persons, the Fund must withhold U.S. federal withholding tax at the rate of 30% (or such lower rate as prescribed by an applicable tax treaty) 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 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, BEFORE MAKING AN INVESTMENT IN THE FUND.

These financial statements are the responsibility of the Fund's management. Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of March 15, 2004, by correspondence with the Fund's custodian. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

ORGANIZATION Calamos Strategic Total Return Fund (the "Fund") is a diversified, closed-end management investment company, organized on December 31, 2003 which has had no operations other than the sale and issuance of 14,000 shares of beneficial interest at an aggregate purchase price of $200,130 to Calamos Asset Management, Inc. (the "Investment Adviser" or "Calamos"). The Fund estimates that it will offer 170,000,000 common shares in its initial offering. The Investment Adviser has agreed to reimburse the amount by which the aggregate of all of the Fund's organizational expenses and all offering costs (other than the sales load) exceeds $0.03 per share. Accordingly, the Fund's share of offering costs will be recorded as a reduction of the proceeds from the sale of its Common Shares upon the commencement of the Fund's operations. Estimated offering costs to be borne by the Fund total $1,790,132. Estimated organizational costs of $96,729 are accrued and expensed in the accompanying financial statements. The Fund currently anticipates that it will issue Preferred Shares as soon as practicable after the closing of the initial offering of common shares. If the Fund completes an offering of Preferred Shares, the Fund will also pay, and common shareholders will effectively bear, the offering costs in connection with such offering and expenses related to the ongoing maintenance of such shares. 2. ACCOUNTING POLICIES The preparation of the financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. Actual results could differ from these estimates. 3. AGREEMENTS The Fund has entered into an Investment Advisory Agreement with Calamos, which provides for payment of a monthly fee computed at the annual rate of 1.00% of the Fund's average weekly Total Managed Assets. "Total Managed Assets" means the total assets of the Fund (including any assets attributable to leverage) minus accrued liabilities (other than liabilities representing leverage). For purposes of calculating "Total Managed Assets," the liquidation preference of any preferred shares outstanding is not considered a liability. The Fund and such other funds advised by Calamos that may be a part of these arrangements (the Fund and such other funds are collectively referred to as the "Calamos Funds") have entered into a Fund Accounting Servicing Agreement with State Street Bank & Trust Co. ("State Street"). The Calamos Funds will pay State Street a monthly fee based on combined managed assets of the Calamos Funds ("Combined Assets") at the annual rate of 0.0225% for the first $3 billion of Combined Assets and 0.0150% for the Combined Assets that exceed $3 billion. The Calamos Funds (including the Fund) have also entered into a Financial Accounting Servicing Agreement with Calamos. The Calamos Funds will pay Calamos a monthly fee based on Combined Assets at the annual rate of 0.0175% on the first $1 billion of Combined Assets; 0.0150% on the next $1 billion of Combined Assets; and 0.0110% on Combined Assets that exceed $2 billion. Each fund of the Calamos Funds will pay its pro-rata share of the fees payable to State Street and Calamos based on relative managed assets of each fund. 4. FEDERAL INCOME TAXES The Fund intends to qualify as a "regulated investment company" and as such (and by complying with the applicable provisions of the Internal Revenue Code of 1986, as amended) will not be subject to Federal income tax on taxable income (including realized capital gains) that is distributed to shareholders.

Dividends and distributions are assumed, for purposes of this calculation, to be reinvested at prices obtained under the Fund's dividend reinvestment plan. Total return is not annualized for periods less than one year. Brokerage commissions are not reflected. (d) Annualized. NOTES TO FINANCIAL STATEMENTS NOTE 1 -- ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES ORGANIZATION - CALAMOS Strategic Total Return Fund (the "Fund"), was organized as a Delaware Statutory Trust on December 30, 2003 and is registered under the Investment Company Act of 1940 as a diversified, closed-end management investment company. The Fund commenced operations on March 26, 2004. The Fund's investment objective is to provide total return, through a combination of capital appreciation and current income. PORTFOLIO VALUATION - In computing the net asset value of the Fund, securities, including options, that are traded on a national securities exchange are valued at the last reported sales price. Securities quoted on the NASDAQ National Market System are valued at the NASDAQ Official Closing Price ("NOCP"), as determined by NASDAQ, or lacking an NOCP, the last current reported sale price as of the time of valuation. Securities traded in the over-the-counter market and listed securities for which no sales were reported are valued at the mean of the most recently quoted bid and asked prices. Short-term obligations with maturities of 60 days or less are valued at amortized cost, which approximates market value. When market quotations are not readily available or when the valuation methods mentioned above are not reflective of the fair value of the security, the security is valued at a fair value following procedures approved by the Board of Trustees or a committee thereof. These procedures may utilize valuations furnished by pricing services approved by the Board of Trustees or a committee thereof, which may be based on market transactions for comparable securities and various relationships between securities that are generally recognized by institutional traders, a computerized matrix system, or appraisals derived from information concerning the securities or similar securities received from recognized dealers in those securities. Securities that are principally traded in a foreign market are valued as of the close of the appropriate exchange or other designated time. Trading in securities on European and Far Eastern securities exchanges and over-the-counter markets is normally completed at various times before the close of business on each day on which the New York Stock Exchange ("NYSE") is open. Trading of these securities may not take place on every NYSE business day. In addition, trading may take place in various foreign markets on Saturdays or on other days when the NYSE is not open and on which the Fund's net asset value is not calculated. INVESTMENT TRANSACTIONS AND INVESTMENT INCOME -- Short term investment transactions are recorded on a trade date basis. Long term investment transactions are recorded on a trade date plus one basis, except for October 31st and April 30th, which are recorded on trade date. Realized gains and losses from investment transactions are recorded on an identified cost basis. Interest income is recognized using the accrual method and includes accretion of original issue and market discount and amortization of premium. Dividend income is recognized on the ex-dividend date, except that certain dividends from foreign securities are recorded as soon as the information becomes available. FOREIGN CURRENCY TRANSLATION -- Values of investments denominated in foreign currencies are converted into U.S. dollars using the spot market rate of exchange at the time of valuation. Purchases and sales of investments and dividend and interest income are translated into U.S. dollars using the spot market rate of exchange prevailing on the respective dates of such transaction. Realized foreign exchange losses of $110,331, and unrealized foreign exchange losses of $41,923 are included as a component of net realized gain/loss on investments, options, and forward foreign currency contracts and change in net unrealized appreciation/depreciation on investments, options, and forward foreign currency contracts, respectively. FEDERAL INCOME TAXES -- No provision has been made for Federal income taxes since the Portfolio is taxed as a "regulated investment company" under Subchapter M of the Internal Revenue Code of 1986. NOTES TO FINANCIAL STATEMENTS DIVIDENDS -- Dividends payable to shareholders are recorded on the ex-dividend date. Income and capital gain dividends are determined in accordance with income tax regulations, which may differ from accounting principles generally accepted in the United States. These differences are primarily due to differing treatments for foreign currency transactions and contingent payment debt instruments. USE OF ESTIMATES -- The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates. NOTE 2 -- INVESTMENT ADVISOR AND TRANSACTIONS WITH AFFILIATES The Fund has entered into an Investment Advisory Agreement with Calamos, which provides for payment of a monthly fee computed at the annual rate of 1.00% of the Fund's average weekly Total Managed Assets. "Total Managed Assets" means the total assets of the Fund (including any assets attributable to leverage) minus accrued liabilities (other than liabilities representing leverage). For purposes of calculating "Total Managed Assets," the liquidation preference of any preferred shares outstanding is not considered a liability. The Fund and such other funds advised by Calamos that may be a part of these arrangements (the Fund and such other funds are collectively referred to as the "Calamos Funds") has entered into a Fund Accounting Servicing Agreement with State Street Bank & Trust Co. ("State Street"). The Calamos Funds will pay State Street a monthly fee based on combined managed assets of the Calamos Funds ("Combined Assets") at the annual rate of 0.0225% for the first $3 billion of Combined Assets and 0.0150% for the Combined Assets that exceed $3 billion. The Calamos Funds (including the Fund) have also entered into a Financial Accounting Servicing Agreement with Calamos. The Calamos Funds will pay Calamos a monthly fee based on Combined Assets at the annual rate of 0.0175% on the first $1 billion of Combined Assets; 0.0150% on the next $1 billion of Combined Assets; and 0.0110% on Combined Assets that exceed $2 billion. Each fund of the Calamos Funds will pay its pro-rate share of the fees payable to State Street and Calamos based on relative managed assets of each fund. Certain portfolio transactions for the Portfolio can be executed through CALAMOS FINANCIAL SERVICES, INC. ("CFS") as broker, consistent with the Portfolio's policy of obtaining best price and execution. During the period ended April 14, 2004, the Portfolio paid no brokerage commissions to CFS on purchases and sales of portfolio securities. Certain officers and trustees of the Trust are also officers and directors of CFS and CAM. All officers and affiliated trustees serve without direct compensation from the Trust. The Fund has adopted a deferred compensation plan (the "Plan"). Under the Plan, a Trustee who is not an "interested person" of CAM and has elected to participate in the Plan (a "participating trustee") may defer receipt of all or a portion of his compensation from the Portfolio. The deferred compensation payable to the participating trustee is credited to the trustee's deferral account as of the business day such compensation would have been paid to the trustee. The value of a trustee's deferred compensation account at any time is equal to what would be the value if the amounts credited to the account had instead been invested in shares of one or more of the funds of the CALAMOS INVESTMENT TRUST as designated by the trustee. Thus, the value of the account increases with contributions to the account or with increases in the value of the measuring shares, and the value of the account decreases with withdrawals from the account or with declines in the value of the measuring shares. If a participating trustee retires, the trustee may elect to receive payments under the plan in a lump sum or in equal installments over a period of five years. If a participating trustee dies, any amount payable under the Plan will be paid to the trustee's beneficiaries. NOTE 3 -- INVESTMENTS Purchases and sales of investments other than short-term obligations for the period ended April 14, 2004 were as follows: Purchases $ 1,828,281,209 Proceeds from sales - The following information is presented on an income tax basis as of April 14, 2004. Differences between amounts for financial statements and Federal income tax purposes are due to timing differences. The cost basis of investments for Federal income tax purposes at April 14, 2004 was as follows: Cost basis of investments $2,079,667,417 Gross unrealized appreciation 11,407,470 Gross unrealized depreciation (33,514,945) Net unrealized appreciation (22,107,475) NOTES TO FINANCIAL STATEMENTS NOTE 4 -- FORWARD FOREIGN CURRENCY CONTRACTS The Fund may engage in portfolio hedging with respect to change in currency exchange rates by entering into foreign currency contracts to purchase or sell currencies. A forward foreign currency contract is a commitment to purchase or sell a foreign currency at a future date at a negotiated forward rate. Risks associated with such contracts include movement in the value of the foreign currency relative to the U.S. dollar and the ability to the counterparty to perform. The net unrealized gain, if any, represents the credit risk to the Fund on a forward foreign currency contract. The contracts are valued daily at forward exchange rates and an unrealized gain or loss is recorded. The Fund realizes a gain or loss upon settlement of the contracts. There were no open forward foreign currency contracts at April 14, 2004. NOTE 5 -- INTEREST BEARING CASH DEPOSIT WITH CUSTODIANS The Fund earns interest on its average daily balance deposited with it custodian. During the period ended April 14, 2004, the fund earned $2.19. NOTE 6 -- CAPITAL Of the 140,514,000 shares of the common stock outstanding, as April 14, 2004 CAM owned 14,000 shares of the Fund. NOTE 7 -- SECURITIES LENDING The Fund may lend certain of its 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 generally would call the loan in an attempt to permit voting of the securities. 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. In an effort to reduce these risks, the investment manager will monitor the creditworthiness of the firms to which the Fund lends securities. For the period ended April 14, 2004, the Fund did not loan any of its securities to broker-dealers and banks.

As used in Part I and Part II of this Statement, capitalized terms shall have the meanings provided in Section 17 of Part I and Section 1 of Part II of this Statement. PART I: TERMS OF PREFERRED SHARES 1. Number of Shares; Ranking. (a) The initial number of authorized shares constituting the Series M Preferred Shares is 7,040 shares, Series TU Preferred Shares is 7,040 shares, Series W Preferred Shares is 7,040 shares, Series TH Preferred Shares is 7,040 shares, Series F Preferred Shares is 7,040 shares, Series A Preferred Shares is 4,000 shares and Series B Preferred Shares is 4,000 shares. No fractional shares of any Series shall be issued. A-2 (b) Shares of each Series that at any time have been redeemed or purchased by the Trust shall, after such redemption or purchase, have the status of authorized but unissued preferred shares of beneficial interest. (c) Shares of each Series shall rank on a parity with shares of any other Series of preferred shares of the Trust (including any other Preferred Shares) as to the payment of dividends to which such shares are entitled. (d) No Holder of shares of any Series shall have, solely by reason of being such a holder, any preemptive exchange, conversion or other right to acquire, purchase or subscribe for any shares of any Series, Common Shares or other securities of the Trust which it may hereafter issue or sell. The Preferred Shares shall not be subject to any sinking fund. 2. Dividends. (a) The Holders of shares of each Series shall be entitled to receive, when, as and if declared by the Board of Trustees, out of funds legally available therefor, cumulative cash dividends on their shares at the Applicable Rate, determined as set forth in paragraph (c) of this Section 2, and no more, payable on the respective dates determined as set forth in paragraph (b) of this Section 2. Dividends on the Outstanding shares of each Series issued on the Date of Original Issue shall accumulate from the Date of Original Issue. (b) (i) Dividends shall be payable when, as and if declared by the Board of Trustees following the initial Dividend Payment Date, subject to subparagraph (b)(ii) of this Section 2, on the shares of each Series, as follows: (A) with respect to any Dividend Period of one year or less, on the Business Day following the last day 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 Period. (ii) If a day for payment of dividends resulting from the application of subparagraph (b) above is not a Business Day, then the Dividend Payment Date shall be the first Business Day following 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 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 A-3 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 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 Trust has declared a Special Dividend Period and there are not Sufficient Clearing Orders, the dividend rate for the next Dividend Period will be the same as during the current Dividend Period. If as a result of an unforeseeable disruption of the financial markets, an Auction cannot be held, 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 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 A-4 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 Paying Agent, and (iii) the Trust has redeemed the full number of preferred shares required to be redeemed by any provision for mandatory 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 Statement. (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 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 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 A-5 other such series of shares of beneficial interest ranking on 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 shares of beneficial interest ranking on 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 shares of beneficial interest ranking on parity therewith bear to each other. 3. Redemption. (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 gives a notice of redemption to the Auction Agent under paragraph (b) of this Section 3. (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 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 A-6 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 Preferred 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 and (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 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 A-7 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. The Trust shall provide Fitch (if Fitch is then rating the Preferred Shares) written notice of the Trust's intent to redeem shares pursuant to Section 3(a) above. (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, and upon request, 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. (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 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 A-8 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 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 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, and senior securities representing indebtedness as defined in the 1940 Act, 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 this Statement 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 11 of Part I of this Statement. 4. Designation of Dividend Period. (a) The initial Dividend Period for each Series shall be the period from the Date of Original Issue to the initial Dividend Payment Date 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 A-9 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, and (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. (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 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 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 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-10 (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. The Board of Trustees will determine to which class or classes the trustees elected by the outstanding preferred shares will be assigned and the holders of outstanding preferred shares shall only be entitled to elect the trustees so designated as being elected by the holders of 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. 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 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 A-11 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 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, 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-12 (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, or arising in connection with any futures contracts or options thereon, interest rate swap or cap transactions, forward rate transactions, put or call options or other similar transactions, (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 any Series) that any such amendment, alteration or repeal would not adversely affect the rating then assigned by such Rating Agency. A-13 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 preferred shares, 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. A-14 The Board of Trustees may amend the definition of Standard Dividend Period to change the Dividend Period with respect to one or more Series without the vote or consent of the holders of shares of preferred, including each series, or any other shareholder of the Trust, and any such change will not be deemed to affect the preferences, rights or powers of Preferred Shares or the Holders thereof. 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. (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 A-15 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.

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 Trust may remove the Auction Agent provided that prior to such removal the Trust 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, S&P 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 S&P, Fitch or any Other Rating Agency that is rating such shares so requires, the Trust will not, unless it has received written confirmation from S&P (if S&P is then rating the Preferred Shares), Fitch (if Fitch 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) issue any additional class or series of shares ranking prior to the Preferred Shares with respect to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up of the Trust; (b) issue additional shares of any Series of Preferred Shares, including any Series previously purchased or redeemed by the Trust; (c) issue senior securities representing indebtedness as defined under the 1940 Act; (d) engage in any short sales of securities; (e) lend portfolio securities; (f) merge or consolidate into or with any other entity; (g) borrow money except for the purpose of clearing transactions in portfolio securities (which borrowings shall under any circumstances be limited to the lesser of $10 million and an A-16 amount equal to 5% of the Market Value of the Trust's total assets at the time of such borrowings and which borrowings shall be repaid within 60 days and not to be extended or renewed and shall not cause the aggregate Discounted Value of the S&P Eligible Assets or the Fitch Eligible Assets to be less than the Preferred Shares Basic Maintenance Amount); (h) engage in dollar rolls and reverse repurchase agreements if, at the time the Trust enters into such agreements, such activity results in a failure to maintain the 1940 Act Preferred Shares Asset Coverage or the Preferred Shares Basic Maintenance Amount, or if any such dollar rolls and reverse repurchase agreements have a maturity of greater than 30 days. 12.

(h) The Auditor's Certificates referred to in paragraph (g) above will confirm, based upon the independent auditor's review of portfolio data provided by the Trust, (i) the mathematical accuracy of the calculations reflected in the related Preferred Shares Basic Maintenance Amount Certificates and 1940 Act Preferred Shares Asset Coverage Certificates and (ii) that, based upon such calculations, the Trust had, at such Valuation Date, met the Preferred Shares Basic Maintenance Amount Test. (i) In the event that a Preferred Shares Basic Maintenance Certificate or 1940 Act Preferred Shares Asset Coverage Certificate with respect to an applicable Valuation Date is not delivered within the time periods specified in this Section 12, the Trust shall be deemed to have failed to meet the Preferred Shares Basic Maintenance Amount Test or the 1940 Act Preferred Shares Asset Coverage, as the case may be, on such Valuation Date for purposes of Section 12(b) of Part I of this Statement.

TERM TO MATURITY OF CORPORATE DEBT SECURITY UNRATED(1) NOT RATED OR BELOW AAA AA A BBB BB BB 3 years or less (but longer than 1 year)..... 106.38% 108.11% 109.89% 111.73% 129.87% 151.52% 5 years or less (but longer than 3 years).... 111.11 112.99 114.94 116.96 134.24 151.52 7 years or less (but longer than 5 years).... 113.64 115.61 117.65 119.76 135.66 151.52 10 years or less (but longer than 7 years)... 115.61 117.65 119.76 121.95 136.74 151.52 15 years or less (but longer than 10 years).. 119.76 121.95 124.22 126.58 139.05 151.52 More than 15 years........................... 124.22 126.58 129.03 131.58 144.55 151.52 ------------------ (1) If a security is not rated by Fitch but is rated by two other Rating Agencies, then the lower of the ratings on the security from the two other Rating Agencies will be used to determine the Fitch Discount Factor (e.g., where the S&P rating is A- and the Moody's rating is Baa1, a Fitch rating of BBB+ will be used). If a security is not rated by Fitch but is rated by only one other Rating Agency, then the rating on the security from the other Rating Agency will be used to determine the Fitch Discount Factor (e.g., where the only rating on a security is an S&P rating of AAA, a Fitch rating of AAA will be used, and where the only rating on a security is a Moody's rating of Ba3, a Fitch rating of BB- will be used). If a security is not rated by any Rating Agency, the Trust will use the percentage set forth under "Unrated" in this table. (ii) Convertible securities. The Fitch Discount Factor applied to convertible securities is (A) 200% for investment grade convertibles and (B) 222% for below investment grade convertibles so long as such convertible securities have neither (x) conversion premium greater than 100% nor (y) have a yield to maturity or yield to worst of >15.00% above the relevant Treasury curve. The Fitch Discount Factor applied to convertible securities which have conversion premiums of greater than 100% is (A) 152% for investment grade convertibles and (B) 179% for below investment grade convertibles so long as such convertible securities do not have a yield to maturity or yield to worst of > 15.00% above the relevant Treasury curve. The Fitch Discount Factor applied to convertible securities which have a yield to maturity or yield to worst of > 15.00% above the relevant Treasury curve is 370%. If a security is not rated by Fitch but is rated by two other Rating Agencies, then the lower of the ratings on the security from the two other Rating Agencies will be used to determine the Fitch Discount Factor (e.g., where the S&P rating is A- and the Moody's rating is Baa1, a Fitch rating of BBB+ will be used). If a security is not rated by Fitch but is rated by only one other Rating Agency, then the rating on the security from the other Rating Agency will be used to determine the Fitch Discount Factor (e.g., where the only rating on a security is an S&P rating of AAA, a Fitch rating of AAA will be used, and where the only rating on a security is a Moody's rating of Ba3, a Fitch rating of BB- will be used). If a security is not rated by any Rating Agency, the Trust will treat the security as if it were below investment grade. (iii) Preferred securities: The percentage determined by reference to the rating of a preferred security in accordance with the table set forth below. A-22 NOT RATED PREFERRED SECURITY(1) OR BELOW AAA AA A BBB BB BB Taxable Preferred............. 130.58% 133.19% 135.91% 138.73% 153.23% 161.08% Dividend-Received Deduction 163.40% 163.40% 163.40% 163.40% 201.21% 201.21% (DRD) Preferred............ -------------------------- (1) If a security is not rated by Fitch but is rated by two other Rating Agencies, then the lower of the ratings on the security from the two other Rating Agencies will be used to determine the Fitch Discount Factor (e.g., where the S&P rating is A- and the Moody's rating is Baa1, a Fitch rating of BBB+ will be used). If a security is not rated by Fitch but is rated by only one other Rating Agency, then the rating on the security from the other Rating Agency will be used to determine the Fitch Discount Factor (e.g., where the only rating on a security is an S&P rating of AAA, a Fitch rating of AAA will be used, and where the only rating on a security is a Moody's rating of Ba3, a Fitch rating of BB- will be used). If a security is not rated by any Rating Agency, the Trust will use the percentage set forth under "Unrated" in this table. (iv) U.S. Government Securities and U.S. Treasury Strips: DISCOUNT TIME REMAINING TO MATURITY FACTOR 1 year or less............................. 100% 2 years or less (but longer than 1 year)... 103% 3 years or less (but longer than 2 years).. 105% 4 years or less (but longer than 3 years).. 107% 5 years or less (but longer than 4 years).. 109% 7 years or less (but longer than 5 years).. 112% 10 years or less (but longer than 7 years). 114% 15 years or less (but longer than 10 years) 122% 20 years or less (but longer than 15 years) 130% 25 years or less (but longer than 20 years) 146% Greater than 30 years...................... 154% (v) Short-Term Investments and Cash: The Fitch Discount Factor applied to short-term portfolio securities, including without limitation Debt Securities, Short Term Money Market Instruments and municipal debt obligations, will be (A) 100%, so long as such portfolio securities mature or have a demand feature at par exercisable within the Fitch Exposure Period; (B) 115%, so long as such portfolio securities mature or have a demand feature at par not exercisable within the Fitch Exposure Period; and (C) 125%, so long as such portfolio securities neither mature nor have a demand feature at par exercisable within the Fitch Exposure Period. A Fitch Discount Factor of 100% will be applied to cash. (vi) Rule 144A Securities: The Fitch Discount Factor applied to Rule 144A Securities will be 110% of the Fitch Discount Factor which would apply were the securities registered under the Securities Act. (vii) Foreign Bonds: The Fitch Discount Factor (A) for a Foreign Bond the principal of which (if not denominated in U.S. dollars) is subject to a currency hedging transaction will be the Fitch Discount Factor that would otherwise apply to such Foreign Bonds in accordance with this definition and (B) for (1) a Foreign Bond the principal of which (if not denominated in U.S. dollars) is not subject to a currency hedging transaction and (2) a bond issued in a currency other than U.S. dollars by a corporation, limited liability company or limited partnership domiciled in, or the government or any agency, instrumentality or political subdivision of, a nation other than an Approved Foreign Nation, will be 370%.

Foreign Bonds held by the Trust will qualify as Fitch Eligible Assets only up to a maximum of 20% of the aggregate Market Value of all assets constituting Fitch Eligible Assets. Similarly, Canadian Bonds held by the Trust will qualify as Fitch Eligible Assets only up to a maximum of 20% of the aggregate Market Value of all assets constituting Fitch Eligible Assets. Notwithstanding the limitations in the two preceding sentences, Foreign Bonds and Canadian Bonds held by the Trust will qualify as Fitch Eligible Assets only up to a maximum of 30% of the aggregate Market Value of all assets constituting Fitch Eligible Assets. In addition, bonds which are issued in connection with a reorganization under U.S. federal bankruptcy law ("Reorganization Bonds") will be considered debt securities constituting Fitch Eligible Assets if (a) they provide for periodic payment of interest in cash in U.S. dollars or euros; (b) they do not provide for conversion or exchange into equity capital at any time over their lives; (c) they have been registered under the Securities Act or are restricted as to resale under federal securities laws but are eligible for trading under Rule 144A promulgated pursuant to the Securities Act as determined by the Trust's investment manager or portfolio manager acting pursuant to procedures approved by the Board of Trustees of the Trust; (d) they were issued by a U.S. corporation, limited liability company or limited partnership; and (e) at the time of purchase at least one year had elapsed since the issuer's A-24 reorganization.

Where the Trust sells an asset and agrees to repurchase such asset in the future, the Discounted Value of such asset will constitute a Fitch Eligible Asset and the amount the Trust is required to pay upon repurchase of such asset will count as a liability for the purposes of the Preferred Shares Basic Maintenance Amount. Where the Trust purchases an asset and agrees to sell it to a third party in the future, cash receivable by the Trust thereby will constitute a Fitch Eligible Asset if the long-term debt of such other party is rated at least A-- by Fitch or the equivalent by another Rating Agency and such A-25 agreement has a term of 30 days or less; otherwise the Discounted Value of such purchased asset will constitute a Fitch Eligible Asset.

The foreign securities held by the Trust 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.

provided, however, that any such non-S&P rated short-term Municipal Obligations which have demand features exercisable within 30 days or less must be backed by a letter of credit, liquidity facility or guarantee from a bank or other financial institution with a short-term rating of at least A-l+ from S&P ; and further provided that such non-S&P rated short-term Municipal Obligations may comprise no more than 50% of short-term Municipal Obligations that qualify as S&P Eligible Assets; provided, however, that Municipal Obligations not rated by S&P but rated equivalent to BBB or lower by another nationally recognized statistical rating organization, rated BB+ or lower by S&P or non-rated (such Municipal Obligations are hereinafter referred to as "High Yield Securities") may comprise no more than 20% of the short-term Municipal Obligations that qualify as S&P Eligible Assets; (ii) the S&P Discount Factor for Receivables for Municipal Obligations Sold that are due in more than five Business Days from such Valuation Date will be the S&P Discount Factor applicable to the Municipal Obligations sold; (iii) no S&P Discount Factor will be applied to cash or to Receivables for Municipal Obligations Sold if such receivables are due within five Business Days of such Valuation Date; and (iv) except as set forth in clause (i) above, in the case of any Municipal Obligation that is not rated by S&P but qualifies as an S&P Eligible Asset pursuant to clause (iii) of that definition, such Municipal Obligation will be deemed to have an S&P rating one full rating category lower than the S&P rating category that is the equivalent of the rating category in which such Municipal Obligation is placed by a nationally recognized statistical rating organization. "Receivables for Municipal Obligations Sold," for purposes of calculating S&P Eligible Assets as of any Valuation Date, means the book value of receivables for Municipal Obligations sold as of or prior to such Valuation Date. The Trust may adopt S&P Discount Factors for Municipal Obligations other than Municipal Obligations provided that S&P advises the Trust in writing that such action will not adversely affect its then current rating on the Preferred Shares. For purposes of the foregoing, Anticipation Notes rated SP-1+ or, if not rated by S&P, equivalent to A-l+ or SP-1+ by another nationally recognized statistical rating organization, on a case by case basis, which do not mature or have a demand feature at par exercisable in 30 days and which do not have a long-term rating, shall be considered to be short-term Municipal Obligations.

No S&P Discount Factor will be applied to Money Market Funds rated AAAm by S&P with effective next day maturities. A-33 Receivables due within five business days of a valuation will be treated as cash and are valued at 100%. Receivables that are due in more than five business days of a Valuation Date qualify as an S&P Eligible Asset at a value no greater than the settlement price discounted at the applicable credit rating and/or exposure period discount factor. For purposes of determining the discount factors applicable to collateral not rated by S&P, the collateral will carry an S&P rating one full rating category lower than the equivalent S&P rating.

(E) For the purpose of calculating the Preferred Shares Basic Maintenance Amount: (i) 90% of any positive mark-to-market valuation of the Trust's rights will be S&P Eligible Assets and 100% of any negative mark-to-market valuation of the Trust's rights will be included in the calculation of the basic maintenance amount. A-40 (F) The Trust must maintain liquid assets with an aggregate value at least equal to the net amount of the excess, if any, of the Trust's obligations over its entitlement with respect to each swap.

(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-49 (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; A-50 (ii) if Sufficient Clearing Bids for shares of such Series do not exist (other than because all of the Outstanding shares of such Series are subject to Submitted Hold Orders), that the Applicable Rate for all shares of such Series for the next succeeding 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 A-51 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 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 A-52 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 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.

CALAMOS STRATEGIC TOTAL RETURN FUND By:________________________________ Name: James S. Hamman, Jr. Title: Secretary WITNESS: By:__________________________________ Name: Ian J. McPheron Title: Assistant Secretary 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. ------------------------ (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 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. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present which make the long-term risk in Aa-rated securities appear somewhat larger than those securities rated Aaa. 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. B-2 Market participants must determine whether any particular note is rated, and if so, at what rating level. 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 B-3 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 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. B-5
