PROSPECTUS

PIMCO High Income Fund

Auction Rate Cumulative Preferred Shares 7,200 Shares, Series M 7,200 Shares, Series T 7,200 Shares, Series W 7,200 Shares, Series TH 7,200 Shares, Series F Liquidation Preference $25,000 per Share


PIMCO High Income Fund, or the Fund, is offering 7,200 Series M, 7,200 Series T, 7,200 Series W, 7,200 Series TH and 7,200 Series F Auction Rate Cumulative Preferred Shares (collectively, "Preferred Shares"). The Fund is a recently organized, diversified, closed-end management investment company.

Investment Objectives. The Fund's primary investment objective is to seek high current income. Capital appreciation is a secondary objective.

Portfolio Management Strategies. The Fund is managed according to a dynamic asset allocation strategy that focuses on credit quality analysis, duration management, broad diversification among issuers, industries and sectors, and other risk management techniques. The portfolio manager attempts to identify investments that provide high current income and/or opportunities for capital appreciation through fundamental research, driven by independent credit analysis and proprietary analytical tools, and also uses a variety of techniques designed to control risk and minimize exposure to issues that the portfolio manager believes are more likely to default or otherwise depreciate in value over time. The Fund will normally invest at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are, at the time of purchase, rated below investment grade (below Baa by Moody's Investors Service, Inc. ("Moody's"), below BBB by either Standard & Poor's ("S&P") or Fitch, Inc. ("Fitch Ratings"), or below a comparable rating by Dominion Bond Rating Service Limited ("Dominion")) or unrated but judged by the portfolio manager to be of comparable quality. Debt securities of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as "junk bonds." Because of the risks involved in investing in junk bonds, an investment in the Fund should be considered speculative. While the Fund's relative emphasis on different credit quality segments of the

Investing in Preferred Shares involves risks. You should read the discussion of the material risks of investing in the Fund in "Risks" beginning on page 32. Certain of these risks are summarized in "Special Risk Considerations," beginning on page 6.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or determined if this prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The public offering price per share will be increased by the amount of dividends, if any, that have accumulated from the date the Preferred Shares are first issued.

The Underwriters are offering the Preferred Shares subject to the condition that the Preferred Shares be rated "Aaa" by Moody's and "AAA" by Fitch Ratings as of the time of delivery of the Preferred Shares to the broker-dealers and subject to certain other conditions. The Underwriters expect to deliver the Preferred Shares to an investor's broker-dealer, in book-entry form through The Depository Trust Company, on or about June 26, 2003.

below investment grade credit spectrum may vary over time, the portfolio manager believes that under current market conditions certain securities in the upper tier of the below investment grade credit spectrum offer opportunities for attractive yield relative to associated risk. Accordingly, the Fund will, under current market conditions, tend to focus on securities that are rated BB/Ba or B by one or more rating agencies or unrated but judged by the portfolio manager to be of comparable quality. The Fund will not invest more than 10% of its total assets in securities that are, at the time of purchase, rated CCC/Caa or lower by each agency rating the security or unrated but judged by the portfolio manager to be of comparable quality.

Portfolio Contents. Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are, at the time of purchase, rated below investment grade (below Baa by Moody's, below BBB by either S&P or Fitch Ratings, or below a comparable rating by Dominion) or unrated but judged by the portfolio manager to be of comparable quality. Within this area of the credit spectrum, the Fund will invest in a diversified portfolio of U.S. dollar-denominated debt obligations of varying maturities and other income-producing securities. These may include bonds, debentures, notes and similar types of debt instruments, including mortgage- and asset-backed securities. The rate of interest on an income-producing security may be fixed, floating or variable. While the Fund emphasizes below investment grade debt securities, it may also invest in investment grade debt securities, including U.S. Government securities. The Fund may make use of credit default swaps and other derivative instruments. The Fund cannot assure you that it will achieve its investment objectives.

It is expected that the Fund normally will have an intermediate average portfolio duration (i.e., within a four-to-eight-year time frame), although it may be shorter or longer at any time or from time to time, depending on market conditions. The portfolio manager believes that this duration range offers the opportunity for above-average returns while limiting exposure to interest rate risk.

Certain capitalized terms used in this prospectus are defined in the Glossary that appears at the end of this prospectus.

Investors in Preferred Shares will be entitled to receive cash dividends at an annual rate that may vary for the successive dividend periods for such shares. The dividend rate on the Series M Preferred Shares for the initial period from and including the date of issue through July 7, 2003, will be % per year. The dividend rate on the Series T Preferred Shares for the initial period from and including the date of issue through July 8, 2003, will be % per year. The dividend rate on the Series W Preferred Shares for the initial period from and including the date of issue through July 9, 2003, will be % per year. The dividend rate on the Series TH Preferred Shares for the initial period from and including the date of issue through July 10, 2003, will be % per year. The dividend rate on the Series F Preferred Shares for the initial period from and including the date of issue through July 11, 2003, will be % per year. For each subsequent period, the auction agent will determine the dividend rate for a particular period by an auction conducted in accordance with the procedures described in this prospectus and, in further detail, in Appendix A to the Statement of Additional Information (each an "Auction").

The Preferred Shares, which have no history of public trading, will not be listed on an exchange or automated quotation system. Broker-Dealers may maintain a secondary trading market in the Preferred Shares outside of Auctions; however, they have no obligation to do so, and there can be no assurance that a secondary market for the Preferred Shares will develop or, if it does develop, that it will provide holders with a liquid trading market (i.e., trading will depend on the presence of willing buyers and sellers and the trading price will be subject to variables to be determined at the time of the trade by such Broker-Dealers). A general increase in the level of interest rates may have an adverse effect on the secondary market price of the Preferred Shares, and a selling shareholder that sells Preferred Shares between Auctions may receive a price per share of less than $25,000. The Fund may redeem Preferred Shares as described under "Description of Preferred Shares--Redemption."

The Preferred Shares will be senior in liquidation and distribution rights to the Fund's outstanding common shares. The Fund's common shares are traded on the New York Stock Exchange under the symbol "PHK." This offering is conditioned upon the Preferred Shares' receiving a rating of "Aaa" from Moody's and "AAA" from Fitch Ratings.

You should read this prospectus, which contains important information about the Fund, before deciding whether to invest and retain it for future reference. A Statement of Additional Information, dated June 23, 2003, containing additional information about the Fund, has been filed with the Securities and Exchange Commission and is incorporated by reference in its entirety into this prospectus, which means that it is part of the prospectus for legal purposes.

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. The Fund has not, and the Underwriters have not, authorized anyone to provide you with different information.

SUMMARY

This is only a summary. You should review the more detailed information contained in this prospectus and in the Statement of Additional Information. Certain capitalized terms used in this prospectus are defined in the Glossary that appears at the end of this prospectus.

The Fund....................  PIMCO High Income Fund (the "Fund") is a recently
                              organized, diversified, closed-end management
                              investment company. See "The Fund." The Fund's
                              Common Shares are traded on the New York Stock
                              Exchange under the symbol "PHK." See "Description
                              of Capital Structure." As of June 11, 2003, the
                              Fund had 113,906,981 Common Shares outstanding.

The Offering................  The Fund is offering an aggregate of 7,200 Series
                              M Preferred Shares, 7,200 Series T Preferred
                              Shares, 7,200 Series W Preferred Shares, 7,200
                              Series TH Preferred Shares and 7,200 Series F
                              Preferred Shares, each at a purchase price of
                              $25,000 per share plus accumulated dividends, if
                              any, from the Date of Original Issue. The
                              Preferred Shares are being offered through
                              Citigroup Global Markets Inc., Merrill Lynch,
                              Pierce, Fenner and Smith Incorporated and UBS
                              Securities LLC (together, the "Underwriters").

See "Underwriting." It is a condition to their issuance that the Preferred Shares be issued with a credit quality rating of "Aaa" from Moody's and "AAA" from Fitch Ratings. The Fund will invest the net proceeds of the offering in accordance with the Fund's investment objectives and policies as stated under "The Fund's Investment Objectives and Policies." It is presently anticipated that the Fund will be able to invest substantially all of the net proceeds in U.S. dollar-denominated debt obligations and other investments that meet its investment objectives and policies within three months after the completion of the offering. Pending such investment, it is anticipated that the proceeds will be invested in high quality, short-term securities.

The Preferred Shares will entitle their holders to receive cash dividends at an annual rate that may vary for successive Dividend Periods. In general, except as described under "Description of Preferred Shares--Dividends," each Dividend Period will be seven days. The Auction Agent will determine the Applicable Rate for a particular period by an Auction conducted on the Business Day immediately prior to the start of that Dividend Period.

The Preferred Shares are not listed on an exchange. Instead, investors may buy or sell Preferred Shares at an auction that normally is held weekly, by submitting orders to Broker-Dealers that have entered into an agreement with the Auction Agent and the Fund or to certain other Broker-Dealers. Deutsche Bank Trust Company Americas, the Auction Agent, reviews orders from Broker-Dealers on behalf of Existing Holders that wish to sell, or hold at the auction rate, or hold only at a specified Applicable Rate, and on behalf of Potential Holders that wish to buy, Preferred Shares. The Auction Agent then determines the lowest Applicable Rate that will result in all of the

outstanding Preferred Shares' continuing to be held. The tables below show the dividend rate for, the beginning date of accumulation of and the number of days in the Initial Dividend Period, the first Auction Date for each series of Preferred Shares, the Initial Dividend Payment Date and the day on which each subsequent auction will generally be held for each series of Preferred Shares (unless the then current Dividend Period is a Long-Term Dividend Period, the day that normally would be the Auction Date is not a Business Day or unforeseen events preclude the holding of an Auction).

Investment Objectives and

  Strategies................  Investment Objectives.  The Fund's primary
                              investment objective is to seek high current
                              income. Capital appreciation is a secondary
                              objective. The Fund attempts to achieve these
                              objectives by investing in a diversified
                              portfolio of U.S. dollar-denominated debt
                              obligations and other income-producing securities
                              that are primarily rated below investment grade
                              (or are unrated securities judged by the
                              portfolio manager to be of comparable quality) as
                              described under "--Portfolio Contents" below. The
                              Fund cannot assure you that it will achieve its
                              investment objectives.

                              Portfolio Management Strategies.  In selecting
                              investments for the Fund, Pacific Investment
                              Management Company LLC ("PIMCO"), the Fund's
                              portfolio manager, attempts to identify, through
                              fundamental research, driven by independent
                              credit analysis and proprietary analytical tools,
                              debt obligations and other instruments that
                              provide high current income and/or opportunities
                              for capital appreciation. Investment decisions
                              are based primarily on PIMCO's assessment of the
                              issuer's credit characteristics and the position
                              of the security in the issuer's capital structure
                              in light of PIMCO's outlook for particular
                              industries, the economy and the bond market
                              generally. At the same time, PIMCO uses a variety
                              of techniques, such as credit default swaps,
                              designed to control risk and minimize the Fund's
                              exposure to issues that PIMCO believes are more
                              likely to default or otherwise depreciate in
                              value over time and detract from the Fund's

                                      2

                              overall return to investors. The Fund also
                              attempts to identify investments that may
                              appreciate in value based on PIMCO's assessment
                              of the issuer's credit characteristics, PIMCO's
                              forecast for interest rates and other economic
                              factors. Subject to the guidelines under
                              "--Credit Quality" below, the Fund also has the
                              flexibility to invest in debt obligations of any
                              credit quality based on its assessment of the
                              particular issuer.

                              Dynamic Asset Allocation Strategy.  The Fund does
                              not invest its assets according to predetermined
                              weightings in particular issuers, industries or
                              sectors. Instead, PIMCO attempts to identify
                              quality investments in any industry or sector
                              through fundamental research, driven by
                              independent credit analysis and proprietary
                              analytical tools.

                              Credit Quality.  Under normal market conditions,
                              the Fund seeks to achieve its investment
                              objectives by investing at least 80% of its net
                              assets (plus any borrowings for investment
                              purposes) in debt securities that are, at the
                              time of purchase, rated below investment grade
                              (below Baa by Moody's, below BBB by either S&P or
                              Fitch Ratings, or below a comparable rating by
                              Dominion) or unrated but judged by PIMCO to be of
                              comparable quality. While the Fund's relative
                              emphasis on different credit quality segments of
                              the below investment grade credit spectrum may
                              vary over time, PIMCO believes that under current
                              market conditions certain securities in the upper
                              tier of the below investment grade credit
                              spectrum offer opportunities for attractive yield
                              relative to associated risk. Accordingly, the
                              Fund will, under current market conditions, tend
                              to focus on securities that are rated BB/Ba or B
                              by one or more rating agencies or unrated but
                              judged by PIMCO to be of comparable quality. The
                              Fund will not invest more than 10% of its total
                              assets in securities that are, at the time of
                              purchase, rated CCC/Caa or lower by each agency
                              rating the security or unrated but judged by
                              PIMCO to be of comparable quality. Debt
                              securities of below investment grade quality are
                              regarded as having predominantly speculative
                              characteristics with respect to capacity to pay
                              interest and repay principal, and are commonly
                              referred to as "junk bonds." The Fund may, for
                              hedging or leveraging purposes, make use of
                              credit default swaps, which are contracts whereby
                              one party makes periodic payments to a
                              counterparty in exchange for the right to receive
                              from the counterparty a payment equal to the par
                              (or other agreed-upon) value of a referenced debt
                              obligation in the event of a default by the
                              issuer of the debt obligation. The Fund's use of
                              credit default swaps and certain other derivative
                              instruments will be limited by the Fund's
                              limitations on illiquid investments to the extent
                              they are determined to be illiquid. See "The
                              Fund's Investment Objectives and
                              Strategies--Portfolio Contents and Other
                              Information" for a description of how the Fund
                              treats certain investments for liquidity purposes.

                              Independent Credit Analysis.  PIMCO relies
                              heavily on its own analysis of the credit quality
                              and risks associated with individual debt
                              obligations considered for the Fund, rather than
                              relying exclusively on rating agencies or
                              third-party research. The individuals managing
                              the Fund utilize this information in an attempt
                              to minimize credit risk and identify issuers,
                              industries or sectors that are undervalued or that

                              offer attractive yields relative to PIMCO's
                              assessment of their credit characteristics. This
                              aspect of PIMCO's capabilities will be
                              particularly important because of the Fund's
                              emphasis on below investment grade debt
                              securities.

                              Duration Management.  The average portfolio
                              duration of the Fund will normally be within an
                              intermediate range (i.e., a four-to-eight-year
                              time frame) based on PIMCO's forecast for
                              interest rates, although it may be shorter or
                              longer at any time or from time to time,
                              depending on market conditions. Duration is a
                              measure of the expected life of a debt security
                              that is used to determine the sensitivity of the
                              security's price to changes in interest rates.
                              PIMCO believes that maintaining duration at a
                              fairly stable level within this intermediate
                              range offers the opportunity for above-average
                              returns while limiting exposure to interest rate
                              volatility and related risk. The Fund may utilize
                              certain strategies, including investments in
                              structured notes or interest rate swap or cap
                              transactions, for the purpose of reducing the
                              interest rate sensitivity of the portfolio,
                              although there is no assurance that it will do so
                              or that such strategies will be successful.

                              Diversification.  Subject to the availability of
                              suitable investment opportunities, PIMCO will
                              attempt to diversify the Fund's investments
                              broadly in an attempt to minimize the portfolio's
                              sensitivity to credit and other risks associated
                              with a particular issuer, industry or sector, or
                              to the impact of a single economic, political or
                              regulatory occurrence.

                              Portfolio Contents.  Under normal market
                              conditions, the Fund seeks to achieve its
                              investment objectives by investing at least 80%
                              of its net assets (plus any borrowings for
                              investment purposes) in debt securities that are,
                              at the time of purchase, rated below investment
                              grade (below Baa by Moody's, below BBB by either
                              S&P or Fitch Ratings, or below a comparable
                              rating by Dominion) or unrated but judged by
                              PIMCO to be of comparable quality. Within this
                              area of the credit spectrum, the Fund will invest
                              in a diversified portfolio of U.S.
                              dollar-denominated debt obligations of varying
                              maturities and other income-producing securities.
                              These may include bonds, debentures, notes and
                              other similar types of debt instruments, such as
                              asset-backed securities, as well as preferred
                              shares, bank loans and loan participations,
                              commercial mortgage securities, payment-in-kind
                              securities, zero-coupon bonds, bank certificates
                              of deposit, fixed time deposits and bankers'
                              acceptances, structured notes and other hybrid
                              instruments, municipal securities,
                              mortgage-backed securities and other types of
                              asset-backed securities issued on a public or
                              private basis, and real estate investment trusts.
                              The Fund will not invest in interest-only or
                              principal-only securities or inverse floating
                              rate securities. Certain debt instruments, such
                              as convertible bonds, also may include the right
                              to participate in equity appreciation, and PIMCO
                              will generally evaluate those instruments based
                              primarily on their debt characteristics. The Fund
                              may invest in securities of companies with small
                              market capitalizations. The rate of interest on

                                      4

                              an income-producing security may be fixed,
                              floating or variable. U.S. dollar-denominated
                              debt securities may include those issued by
                              foreign corporations or supra-national government
                              agencies. The Fund may also invest in investment
                              grade debt securities, including U.S. Government
                              securities. The Fund may make use of credit
                              default swaps and other derivative instruments.
                              As a diversified fund, the Fund generally may
                              not, with respect to 75% of its total assets,
                              purchase the securities of any issuer, except
                              securities issued or guaranteed by the U.S.
                              Government or any of its agencies or
                              instrumentalities or securities of other
                              investment companies, if, as a result, (i) more
                              than 5% of the Fund's total assets would be
                              invested in the securities of that issuer, or
                              (ii) the Fund would hold more than 10% of the
                              outstanding voting securities of that issuer. The
                              Fund will not concentrate its investments in a
                              particular industry by investing more than 25% of
                              its total assets in that industry. The Fund's
                              industry concentration policy does not preclude
                              it from focusing investments in issuers in a
                              group of related industrial sectors (such as
                              different types of utilities).

Investment Manager..........  PIMCO Advisors Fund Management LLC (the
                              "Manager") serves as the investment manager of
                              the Fund. Subject to the supervision of the Board
                              of Trustees, the Manager is responsible for
                              managing, either directly or through others
                              selected by it, the investment activities of the
                              Fund and the Fund's business affairs and other
                              administrative matters. The Manager receives an
                              annual fee, payable monthly, in an amount equal
                              to 0.70% of the Fund's average daily net assets
                              (including assets attributable to any Preferred
                              Shares that may be outstanding). The Manager is
                              located at 1345 Avenue of the Americas, New York,
                              New York 10105. Organized in 2000 as a subsidiary
                              successor in the restructuring of a business
                              originally organized in 1987, the Manager
                              provides investment management and advisory
                              services to several closed-end and open-end
                              investment company clients. As of March 31, 2003,
                              the Manager had approximately $17.7 billion in
                              assets under management. Allianz Dresdner Asset
                              Management of America L.P. is the direct parent
                              company of PIMCO Advisors Retail Holdings LLC
                              (formerly PIMCO Advisory Services Holdings LLC),
                              of which the Manager is a wholly owned
                              subsidiary. As of March 31, 2003, Allianz
                              Dresdner Asset Management of America L.P. and its
                              subsidiary partnerships, including PIMCO, had
                              approximately $390 billion in assets under
                              management.

                              The Manager has retained its affiliate, PIMCO, as
                              a sub-adviser to manage the Fund's portfolio
                              investments. See "--Portfolio Manager" below.

Portfolio Manager...........  PIMCO serves as the Fund's sub-adviser
                              responsible for managing the Fund's portfolio
                              investments, and is sometimes referred to herein
                              as the "portfolio manager." Subject to the
                              supervision of the Manager, PIMCO has full
                              investment discretion and makes all
                              determinations with respect to the investment of
                              the Fund's assets.

                              PIMCO is located at 840 Newport Center Drive,
                              Newport Beach, California 92660. Organized in
                              1971, PIMCO provides investment management and
                              advisory services to private accounts of
                              institutional and individual clients and to
                              mutual funds. As of March 31, 2003, PIMCO had
                              approximately $323 billion in assets under
                              management.

                              The Manager (and not the Fund) will pay a portion
                              of the fees it receives to PIMCO in return for
                              PIMCO's services.

Leverage....................  After completion of the offering of Preferred
                              Shares, the Fund anticipates its total leverage
                              from the issuance of Preferred Shares will be
                              approximately 35%. Although the Fund may in the
                              future offer other preferred shares, the Fund
                              does not currently intend to offer preferred
                              shares other than Series M Preferred Shares,
                              Series T Preferred Shares, Series W Preferred
                              Shares, Series TH Preferred Shares and Series F
                              Preferred Shares. The Fund may also use a variety
                              of additional strategies to add leverage to the
                              portfolio, including the use of reverse
                              repurchase agreements, loans of portfolio
                              securities, credit default swap contracts and
                              other derivatives, as well as when-issued,
                              delayed delivery or forward commitment
                              transactions, each of which will amplify the
                              effects of leverage in the Fund's portfolio. The
                              Fund will segregate liquid assets against or
                              otherwise cover its future obligations under such
                              transactions to the extent that, immediately
                              after entering into such a transaction, the
                              Fund's future commitments that it has not
                              segregated liquid assets against or otherwise
                              covered, together with any outstanding Preferred
                              Shares, would exceed 38% of the Fund's total
                              assets.

                              The Fund generally will not utilize leverage if
                              it anticipates that it would result in a lower
                              return to Common Shareholders over time. Use of
                              financial leverage creates an opportunity for
                              increased income for Common Shareholders, but, at
                              the same time, creates the possibility for
                              greater loss (including the likelihood of greater
                              volatility of net asset value and market price of
                              the Common Shares and of dividends), and there
                              can be no assurance that a leveraging strategy
                              will be used or that it will be successful during
                              any period in which it is employed. Because the
                              fees received by the Manager are based on the
                              total net assets of the Fund, the fees will be
                              higher when leverage is utilized through the
                              issuance of Preferred Shares, giving the Manager
                              an incentive to utilize such leverage. See
                              "Risks--Leverage Risk."

Special Risk Considerations. The following describes various principal risks of investing in the Fund. A more detailed description of these and other risks of investing in the Fund is included in the prospectus under the heading "Risks" and in the Statement of Additional Information under the heading "Investment Objectives and Policies."

Risks of investing in Preferred Shares include:

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. As a
                            result, your investment in Preferred Shares may
                            be illiquid. Neither the Broker-Dealers nor the
                            Fund is obligated to purchase Preferred Shares in
                            an Auction or otherwise, nor is the Fund required
                            to redeem Preferred Shares in the event of a
                            failed Auction.

Ratings and Asset Coverage
 Risk...................    A Rating Agency could downgrade the Preferred
                            Shares, which could affect their liquidity and
                            value. In addition, the Fund may be forced to
                            redeem your Preferred Shares to meet regulatory
                            or Rating Agency asset coverage requirements. The
                            Fund may also voluntarily redeem Preferred Shares
                            under certain circumstances. The Fund may not
                            redeem Preferred Shares if such a redemption
                            would cause the Fund to fail to meet regulatory
                            or Rating Agency asset coverage requirements, and
                            the Fund may not declare, pay or set apart for
                            payment any dividend or other distribution if
                            immediately thereafter the Fund would fail to
                            meet regulatory asset coverage requirements.

Secondary Market Risk...    You could receive less than the price you paid
                            for your Preferred Shares if you sell them
                            outside of an Auction, especially when market
                            interest rates are rising. Although the
                            Broker-Dealers may maintain a secondary trading
                            market in the Preferred Shares outside of
                            Auctions, they are not obligated to do so, and no
                            secondary market may develop or exist at any time
                            for the Preferred Shares.

General risks of investing in the Fund include:

Limited Operating History   The Fund is a recently organized, diversified,
                            closed-end management investment company which
                            has been operational for less than two months.

Credit Risk/High Yield Risk Credit risk is the risk that one or more debt obligations in the Fund's portfolio will decline in price, or fail to pay interest or principal when due, because the issuer of the obligation experiences an actual or perceived decline in its financial status. The Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are, at the time of purchase, rated below investment grade (below Baa by Moody's, below BBB by either S&P or Fitch Ratings, or below a comparable rating by Dominion) or unrated but judged by PIMCO to be of comparable quality, including debt securities that are in default or the issuers of which are in bankruptcy. Debt obligations of below investment grade quality (commonly referred to as "junk bonds") are predominantly speculative with respect to the issuer's capacity to pay interest and repay principal when due, and therefore involve a greater risk of default. The prices of these lower grade obligations are generally

7

                            more volatile and sensitive to actual or
                            perceived negative developments, such as a
                            decline in the issuer's revenues or a general
                            economic downturn, than are the prices of higher
                            grade securities. Because of the Fund's emphasis
                            on below investment grade debt securities,
                            PIMCO's capabilities in this area will be
                            particularly important. See "The Fund's
                            Investment Objectives and Strategies--High Yield
                            Securities ("Junk Bonds")" and "Risks--High Yield
                            Risk" for additional information. Because of the
                            risks involved in investing in junk bonds, an
                            investment in the Fund should be considered
                            speculative.

Interest Rate Risk......    Generally, when market interest rates fall, the
                            prices of debt obligations rise, and vice versa.
                            Interest rate risk is the risk that the debt
                            obligations in the Fund's portfolio will decline
                            in value because of increases in market interest
                            rates. Because market interest rates are
                            currently near their lowest levels in many years,
                            there is a great risk that the Fund's portfolio
                            will decline in value. The prices of long-term
                            debt obligations generally fluctuate more than
                            prices of short-term debt obligations as interest
                            rates change. Because the Fund will normally have
                            an intermediate portfolio duration (i.e., a
                            four-to -eight-year time frame), the Fund's net
                            asset value will tend to fluctuate more in
                            response to changes in market interest rates than
                            if the Fund invested mainly in short-term debt
                            securities. The Fund may utilize certain
                            strategies, including investments in structured
                            notes or interest rate swap or cap transactions,
                            for the purpose of reducing the interest rate
                            sensitivity of the portfolio and decreasing the
                            Fund's exposure to interest rate risk, although
                            there is no assurance that it will do so or that
                            such strategies will be successful. If long-term
                            rates rise, the value of the Fund's investment
                            may decline, reducing asset coverage on the
                            Preferred Shares. The Fund's use of leverage, as
                            described below, will tend to increase interest
                            rate risk. See "Risks--Interest Rate Risk" for
                            additional information.

Leverage Risk...........    The Fund utilizes financial leverage for
                            investment purposes. Leverage risk includes the
                            risk associated with the issuance of Preferred
                            Shares to leverage the Fund's Common Shares. The
                            Fund may also invest in reverse repurchase
                            agreements, loans of portfolio securities, credit
                            default swap contracts and other derivatives, as
                            well as when-issued, delayed delivery or forward
                            commitment transactions, which will amplify the
                            effects of leverage. If the dividend rate on the
                            Preferred Shares exceeds the net rate of return
                            on the Fund's portfolio, the leverage will result
                            in a lower net asset value than if the Fund were
                            not leveraged, and the Fund's ability to pay
                            dividends and to meet its asset coverage
                            requirements on the Preferred Shares would be
                            reduced. In addition, to the extent that any
                            forms of leverage utilized by the Fund are senior
                            to the Preferred Shares, payments to holders of
                            Preferred Shares in liquidation or otherwise will
                            be subject to the prior payment of obligations
                            relating to such other forms of leverage.

                            Because the fees received by the Manager are
                            based on the total net assets of the Fund, the
                            fees will be higher when leverage is utilized

                                    8

                            through the issuance of Preferred Shares, giving
                            the Manager an incentive to utilize such leverage.

Issuer Risk.............    The value of income-producing securities may
                            decline for a number of reasons which directly
                            relate to the issuer, such as management
                            performance, financial leverage and reduced
                            demand for the issuer's goods and services.

Management Risk.........    The Fund is subject to management risk because it
                            is an actively managed portfolio. PIMCO and the
                            individual portfolio managers will apply
                            investment techniques and risk analyses in making
                            investment decisions for the Fund, but there can
                            be no guarantee that these will produce the
                            desired results.

Foreign
(Non-U.S.) Investment Risk The Fund's investments in foreign issuers and in

                            securities denominated in foreign currencies
                            involve special risks. For example, the value of
                            these investments may decline in response to
                            unfavorable political and legal developments,
                            unreliable or untimely information, or economic
                            and financial instability. The value of
                            securities denominated in foreign currencies may
                            fluctuate based on changes in the value of those
                            currencies relative to the U.S. dollar, and a
                            decline in applicable foreign exchange rates
                            could reduce the value of such securities held by
                            the Fund. Foreign settlement procedures also may
                            involve additional risks.

Emerging Markets Risk...    Foreign investment risk may be particularly high
                            to the extent that the Fund invests in securities
                            of issuers based in or securities denominated in
                            the currencies of developing or "emerging market"
                            countries. Investing in securities of issuers
                            based in underdeveloped emerging markets entails
                            all of the risks of investing in securities of
                            foreign issuers to a heightened degree. These
                            heightened risks include: (i) greater risks of
                            expropriation, confiscatory taxation,
                            nationalization, and less social, political and
                            economic stability; (ii) the smaller size of the
                            market for such securities and a lower volume of
                            trading, resulting in lack of liquidity and in
                            price volatility; and (iii) certain national
                            policies which may restrict the Fund's investment
                            opportunities, including restrictions on
                            investing in issuers or industries deemed
                            sensitive to relevant national interests.

Derivatives Risk........    The Fund may utilize a variety of derivative
                            instruments for hedging or risk management
                            purposes or as part of its leveraging or
                            investment strategies, such as options contracts
                            (including options on futures contracts), futures
                            contracts, swap agreements (including credit
                            default swaps) and short sales. Derivatives are
                            subject to a number of risks described elsewhere
                            in this prospectus, such as liquidity risk,
                            interest rate risk, credit risk, leveraging risk
                            and management risk. They also involve the risk
                            of mispricing or improper valuation, the risk of
                            ambiguous documentation, and the risk that
                            changes in the value of a derivative may not
                            correlate perfectly with an underlying asset,
                            interest rate or index. Suitable derivative
                            transactions may not be available in all
                            circumstances, and

                                    9

                            there can be no assurance that the Fund will
                            engage in these transactions to reduce exposure
                            to other risks when that would be beneficial.

Counterparty Risk.......    The Fund will be subject to credit risk with
                            respect to the counterparties to the derivative
                            contracts purchased by the Fund. If a
                            counterparty becomes bankrupt or otherwise fails
                            to perform its obligations under a derivative
                            contract because of financial difficulties, the
                            Fund may experience significant delays in
                            obtaining any recovery under the derivative
                            contract in a bankruptcy or other reorganization
                            proceeding. The Fund may obtain only a limited
                            recovery or may obtain no recovery in such
                            circumstances.

Mortgage-Related Risk...    The Fund may invest in a variety of
                            mortgage-related securities, including commercial
                            mortgage securities and other mortgage-backed
                            instruments. Rising interest rates tend to extend
                            the duration of mortgage-related securities,
                            making them more sensitive to changes in interest
                            rates, and may reduce the market value of the
                            securities. In addition, mortgage-related
                            securities are subject to prepayment risk--the
                            risk that borrowers may pay off their mortgages
                            sooner than expected, particularly when interest
                            rates decline. This can reduce the Fund's returns
                            because the Fund may have to reinvest that money
                            at lower prevailing interest rates. The Fund's
                            investments in other asset-backed securities are
                            subject to risks similar to those associated with
                            mortgage-backed securities, as well as additional
                            risks associated with the nature of the assets
                            and the servicing of those assets.

Smaller Company Risk....    The general risks associated with
                            income-producing securities are particularly
                            pronounced for securities issued by companies
                            with smaller market capitalizations. These
                            companies may have limited product lines, markets
                            or financial resources or may depend on a few key
                            employees. As a result, they may be subject to
                            greater levels of credit, market and issuer risk.

Reinvestment Risk.......    Income from the Fund's portfolio will decline if
                            and when the Fund invests the proceeds from
                            matured, traded or called debt obligations at
                            market interest rates that are below the
                            portfolio's current earnings rate.

Inflation Risk..........    Inflation risk is the risk that the value of
                            assets or income from the Fund's investments will
                            be worth less in the future as inflation
                            decreases the value of money. As inflation
                            increases, the real, or inflation-adjusted, value
                            of the Preferred Shares and distributions can
                            decline. However, during any periods of rising
                            inflation, dividend payments on Preferred Shares
                            may increase, which would tend to offset this
                            risk.

Liquidity Risk..........    The Fund may invest up to 15% of its total assets
                            in illiquid securities (i.e., securities that
                            cannot be disposed of within seven days in the
                            ordinary course of business at approximately the
                            value at which the Fund has valued the
                            securities). For these purposes, bank loans that
                            are part of an issue of at least $250 million in
                            par value will not be

                                    10

                            considered illiquid, although the Fund's
                            investments in such bank loans, together with its
                            investments in illiquid securities, will not
                            exceed 20% of its total assets. Illiquid
                            securities may trade at a discount from
                            comparable, more liquid investments, and may be
                            subject to wide fluctuations in market value.
                            Also, the Fund may not be able to dispose of
                            illiquid securities when that would be beneficial
                            at a favorable time or price. Below investment
                            grade debt securities tend to be less liquid than
                            higher-rated securities.

Market Disruption and
 Geopolitical Risk......    The war with Iraq, its aftermath and the
                            continuing occupation of Iraq are likely to have
                            a substantial impact on the U.S. and world
                            economies and securities markets. The nature,
                            scope and duration of the war and occupation
                            cannot be predicted with any certainty. Terrorist
                            attacks on the World Trade Center and the
                            Pentagon on September 11, 2001 closed some of the
                            U.S. securities markets for a four-day period,
                            and similar events cannot be ruled out. The war
                            and occupation, terrorism and related
                            geopolitical risks have led, and may in the
                            future lead to, increased short-term market
                            volatility and may have adverse long-term effects
                            on U.S. and world economies and markets
                            generally. Those events could also have an acute
                            effect on individual issuers or related groups of
                            issuers. These risks could also adversely affect
                            individual issuers and securities markets,
                            interest rates, auctions, secondary trading,
                            ratings, credit risk, inflation and other factors
                            relating to the Preferred Shares.

Anti-Takeover Provisions    The Fund's Amended and Restated Agreement and
                            Declaration of Trust dated February 18, 2003 (the
                            "Declaration") includes provisions that could
                            limit the ability of other entities or persons to
                            acquire control of the Fund or convert the Fund
                            to open-end status. See "Anti-Takeover and Other
                            Provisions in the Declaration of Trust."

Dividends on Preferred Shares The Preferred Shares will entitle their holders to receive cash dividends at a rate per annum that may vary for the successive Dividend Periods for such shares. In general, except as described below, each Dividend Period for each series of Preferred Shares subsequent to the Initial Dividend Period will be seven days in length. The Applicable Rate for a particular Dividend Period will be determined by an Auction conducted on the Business Day next preceding the start of such Dividend Period.

Through their Broker-Dealers, Beneficial Owners and Potential Beneficial Owners of Preferred Shares may participate in Auctions, although, except in the case of Special Dividend Periods of longer than 28 days, Beneficial Owners desiring to continue to hold all of their Preferred Shares regardless of the Applicable Rate resulting from Auctions need not participate. For an explanation of Auctions and the method of determining the Applicable Rate, see "Description of Preferred Shares--The Auction."

Except as described herein, investors in Preferred Shares will not receive certificates representing ownership of their shares. Ownership

11

of Preferred Shares will be maintained in book-entry form by the Securities Depository or its nominee for the account of the investor's Agent Member. The investor's Agent Member, in turn, will maintain records of such investor's beneficial ownership of Preferred Shares. Accordingly, references herein to an investor's investment in or purchase, sale or ownership of Preferred Shares are to purchases, sales or ownership of those shares by Beneficial Owners.

After the Initial Dividend Period, each Subsequent Dividend Period for each series of Preferred Shares will generally consist of seven days (a "7-Day Dividend Period"); provided, however, that prior to any Auction, the Fund may elect, subject to certain limitations described herein, upon giving notice to holders thereof, a Special Dividend Period for any or all series. A "Special Dividend Period" is a Dividend Period consisting of a specified number of days, evenly divisible by seven and not fewer than fourteen nor more than 364 (a "Short Term Dividend Period"), or a Dividend Period consisting of a specified period of one whole year or more but not greater than five years (a "Long Term Dividend Period"). Dividends on the Preferred Shares offered hereby are cumulative from the Date of Original Issue and are payable when, as and if declared by the Board of Trustees, out of funds legally available therefor, commencing on the Initial Dividend Payment Date. In the case of Dividend Periods that are not Special Dividend Periods, dividends will be payable generally on each succeeding Tuesday for Series M Preferred Shares, on each succeeding Wednesday for Series T Preferred Shares, on each succeeding Thursday for Series W Preferred Shares, on each succeeding Friday for Series TH Preferred Shares and on each succeeding Monday for Series F Preferred Shares, subject to certain exceptions.

Dividends for the Preferred Shares will be paid through the Securities Depository on each Dividend Payment Date. The Securities Depository's normal procedures provide for it to distribute dividends in same-day funds to Agent Members, who are in turn expected to distribute such dividends to the person for whom they are acting as agent in accordance with the instructions of such person. See "Description of Preferred Shares--Dividends."

For each Subsequent Dividend Period, the cash dividend rate on each series of Preferred Shares will be the Applicable Rate that the Auction Agent advises the Fund has resulted from an Auction. See "Description of Preferred Shares--Dividends." The first Auction for each series of the Preferred Shares is scheduled to be held on the ending date for the Initial Dividend Period as set forth in "--The Offering" above.

The Amended Bylaws provide that, until the Fund gives a Request for Special Dividend Period and the related Notice of Special Dividend Period, only 7-Day Dividend Periods will be applicable to each series of Preferred Shares. While the Fund does not currently intend to give a Request for Special Dividend Period with respect to any series of

12

Preferred Shares, it may so elect in the future, subject to, and on, the conditions discussed under "Description of Preferred Shares--Dividends--Notification of Dividend Period."

A Special Dividend Period will not be effective for a series of Preferred Shares unless Sufficient Clearing Bids exist at the Auction in respect of such Special Dividend Period. If Sufficient Clearing Bids do not exist at such Auction, the Dividend Period commencing on the Business Day succeeding such Auction will be a 7-Day Dividend Period, and the holders of the Preferred Shares outstanding immediately prior to such Auction will be required to continue to hold some or all of such shares for such Dividend Period. In addition, the Fund may not give a Notice of Special Dividend Period with respect to the Preferred Shares, or if the Fund has given a Notice of Special Dividend Period for the Preferred Shares, the Fund will be required to give a Notice of Revocation in respect thereof, if either (i) the 1940 Act Preferred Shares Asset Coverage is not satisfied or the Fund fails to maintain Moody's Eligible Assets and Fitch Eligible Assets each with an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount, in each case on each of the two Valuation Dates immediately preceding the Business Day prior to the related Auction Date for the Preferred Shares, or (ii) sufficient funds for the payment of dividends payable on the immediately succeeding Dividend Payment Date have not been irrevocably deposited with the Auction Agent by the close of business on the third Business Day preceding the related Auction Date. In either of such events, the next succeeding Dividend Period will be a 7-Day Dividend Period.

Determination of Maximum

 Applicable Rates..........  Except during a Non-Payment Period, the
                             Applicable Rate for any Dividend Period for
                             Preferred Shares will not be more than the
                             Maximum Applicable Rate applicable to such
                             shares. The Maximum Applicable Rate for each
                             series of Preferred Shares will depend on the
                             credit rating assigned to such shares and on the
                             duration of the Dividend Period. The Maximum
                             Applicable Rate will be the Applicable Percentage
                             of the Reference Rate. The Reference Rate is the
                             applicable "AA" Financial Composite Commercial
                             Paper Rate (for a Dividend Period of fewer than
                             184 days) or the applicable Treasury Index Rate
                             (for a Dividend Period of 184 days or more). The
                             Applicable Percentage will be determined based on
                             the lower of the credit ratings assigned on such
                             date to the Preferred Shares by Moody's and Fitch
                             Ratings, such Applicable Percentage as so
                             determined further subject to upward but not
                             downward adjustment in the discretion of the
                             Board of Trustees after consultation with the
                             Broker-Dealers, as follows:

                           Fitch Ratings  Credit
 Moody's Credit Rating             Rating            Applicable Percentage
------------------------  ------------------------  ------------------------
      Aa3 or above              AA- or above                  150%
        A3 to A1                  A- to A+                    160%
      Baa3 to Baa1              BBB- to BBB+                  250%
       Below Baa3                Below BBB-                   275%

13

                              There is no minimum Applicable Rate in respect of
                              any Dividend Period. The Applicable Rate for any
                              Dividend Period commencing during any Non-Payment
                              Period, and the rate used to calculate the late
                              charge described under "Description of Preferred
                              Shares--Dividends--Non-Payment Period; Late
                              Charge," initially will be 300% of the Reference
                              Rate.

Auction Procedures..........  Separate Auctions will be conducted for each
                              series of Preferred Shares. Unless otherwise
                              permitted by the Fund, Beneficial Owners and
                              Potential Beneficial Owners of Preferred Shares
                              may participate in Auctions only through their
                              Broker-Dealers. Broker-Dealers will submit the
                              Orders of their respective customers who are
                              Beneficial Owners and Potential Beneficial Owners
                              to the Auction Agent, designating themselves as
                              Existing Holders in respect of shares subject to
                              Orders submitted or deemed submitted to them by
                              Beneficial Owners and as Potential Holders in
                              respect of shares subject to Orders submitted to
                              them by Potential Beneficial Owners. On or prior
                              to each Auction Date for the Preferred Shares
                              (usually the Business Day next preceding the
                              first day of each Dividend Period), each
                              Beneficial Owner may submit Orders to its
                              Broker-Dealer as follows:

                                .  Hold Order--indicating its desire to hold
                                   the Preferred Shares without regard to the
                                   Applicable Rate for the next Dividend Period
                                   for such shares.

                                .  Bid--indicating its desire to hold the
                                   Preferred Shares, provided that the
                                   Applicable Rate for the next Dividend Period
                                   for such shares is not less than the rate
                                   per annum specified in such Bid.

                                .  Sell Order--indicating its desire to sell
                                   the Preferred Shares without regard to the
                                   Applicable Rate for the next Dividend Period
                                   for such shares.

                              A Beneficial Owner may submit different types of
                              Orders to its Broker-Dealer with respect to the
                              Preferred Shares then held by such Beneficial
                              Owner, provided that the total number of
                              Preferred Shares covered by such Orders does not
                              exceed the number of Preferred Shares held by
                              such Beneficial Owner. If, however, a Beneficial
                              Owner offers through its Broker-Dealer to
                              purchase additional Preferred Shares in such
                              Auction, such Beneficial Owner, for purposes of
                              such offer to purchase additional shares, will be
                              treated as a Potential Beneficial Owner as
                              described below. Bids by Beneficial Owners
                              through their Broker-Dealers with rates per annum
                              higher than the Maximum Applicable Rate will be
                              treated as Sell Orders. A Hold Order (in the case
                              of an Auction relating to a Dividend Period of 28
                              days or less) or a Sell Order (in the case of an
                              Auction relating to a Special Dividend Period of
                              longer than 28 days) shall be deemed to have been
                              submitted on behalf of a Beneficial Owner if an
                              Order with respect to the Preferred Shares then
                              held by such Beneficial Owner is not submitted on
                              behalf of such Beneficial Owner for any reason,
                              including the failure of a Broker-Dealer to
                              submit such Beneficial Owner's Order to the
                              Auction Agent.

                              Potential Beneficial Owners of Preferred Shares
                              may submit Bids through their Broker-Dealers in
                              which they offer to purchase Preferred Shares if
                              the Applicable Rate for the next Dividend Period
                              for such shares is not less than the rate per
                              annum specified in such Bid. A Bid by a Potential
                              Beneficial Owner with a rate per annum higher
                              than the Maximum Applicable Rate will not be
                              considered.

                              Neither the Fund nor the Auction Agent will be
                              responsible for a Broker-Dealer's failure to act
                              in accordance with the instructions of Beneficial
                              Owners or Potential Beneficial Owners or failure
                              to comply with any of the foregoing.

                              A Broker-Dealer also may hold Preferred Shares
                              for its own account as a Beneficial Owner. A
                              Broker-Dealer thus may submit Orders to the
                              Auction Agent as a Beneficial Owner or a
                              Potential Beneficial Owner and therefore
                              participate in an Auction as an Existing Holder
                              or Potential Holder on behalf of both itself and
                              its customers. Any Order placed with the Auction
                              Agent by a Broker-Dealer as or on behalf of a
                              Beneficial Owner or a Potential Beneficial Owner
                              will be treated in the same manner as an Order
                              placed with a Broker-Dealer by a Beneficial Owner
                              or a Potential Beneficial Owner. Similarly, any
                              failure by a Broker-Dealer to submit to the
                              Auction Agent an Order in respect of any
                              Preferred Shares held by it or its customers who
                              are Beneficial Owners will be treated in the same
                              manner as a Beneficial Owner's failure to submit
                              to its Broker-Dealer an Order in respect of
                              Preferred Shares held by it, as described above.
                              Inasmuch as a Broker-Dealer participates in an
                              Auction as an Existing Holder or a Potential
                              Holder only to represent the interests of a
                              Beneficial Owner or Potential Beneficial Owner,
                              whether it be a customer or itself, all
                              discussion herein relating to the consequences of
                              an Auction for Existing Holders and Potential
                              Holders also applies to the underlying beneficial
                              ownership interests represented thereby.

                              If Sufficient Clearing Bids exist in an Auction
                              for a series of Preferred Shares (that is, in
                              general, the number of Preferred Shares subject
                              to Bids by Potential Holders with rates equal to
                              or lower than the Maximum Applicable Rate is at
                              least equal to the number of Preferred Shares
                              subject to Sell Orders by Existing Holders), the
                              Applicable Rate will be the lowest rate per annum
                              specified in the Submitted Bids which, taking
                              into account such rate per annum and all lower
                              rates per annum bid by Existing Holders and
                              Potential Holders, would result in Existing
                              Holders, and Potential Holders, owning all of the
                              Preferred Shares available for purchase in the
                              Auction. If Sufficient Clearing Bids do not
                              exist, the Dividend Period next following the
                              Auction automatically will be a 7-Day Dividend
                              Period and the Applicable Rate will be the
                              Maximum Applicable Rate, and in such event,
                              Existing Holders that have submitted Sell Orders
                              will not be able to sell in the Auction all, and
                              may not be able to sell any, Preferred Shares
                              subject to such Sell Orders. Thus, in certain
                              circumstances, Existing Holders and, thus, the
                              Beneficial Owners they represent may not have
                              liquidity of investment. If all Existing Holders
                              submit (or are deemed to have submitted) Hold

                                      15

                              Orders in an Auction, the Dividend Period next
                              following the Auction automatically shall be the
                              same length as the immediately preceding Dividend
                              Period, and the Applicable Rate will be 80% of
                              the Reference Rate.

                              The Auction Procedures include a pro rata
                              allocation of shares for purchase and sale, which
                              may result in an Existing Holder selling or
                              holding, or a Potential Holder purchasing, a
                              number of Preferred Shares that is less than the
                              number of Preferred Shares specified in its
                              Order. To the extent the allocation has this
                              result, a Broker-Dealer will be required to make
                              appropriate pro rata allocations among its
                              customers and itself.

                              A Sell Order by an Existing Holder will
                              constitute an irrevocable offer to sell the
                              Preferred Shares subject thereto, and a Bid
                              placed by an Existing Holder also will constitute
                              an irrevocable offer to sell the Preferred Shares
                              subject thereto if the rate per annum specified
                              in the Bid is higher than the Applicable Rate
                              determined in the Auction, in each case at a
                              price per share equal to $25,000. A Bid placed by
                              a Potential Holder will constitute an irrevocable
                              offer to purchase the Preferred Shares subject
                              thereto at a price per share equal to $25,000 if
                              the rate per annum specified in such Bid is less
                              than or equal to the Applicable Rate determined
                              in the Auction. Settlement of purchases and sales
                              will be made on the next Business Day (also a
                              Dividend Payment Date) after the Auction Date
                              through the Securities Depository. Purchasers
                              will make payment through their Agent Members in
                              same-day funds to the Securities Depository
                              against delivery by book-entry to their Agent
                              Members. The Securities Depository will make
                              payment to the sellers' Agent Members in
                              accordance with the Securities Depository's
                              normal procedures, which provide for payment in
                              same-day funds. See "Description of Preferred
                              Shares--The Auction."

Asset Maintenance...........  Under the Amended Bylaws, the Fund must maintain
                              (i) Moody's Eligible Assets and Fitch Eligible
                              Assets each having in the aggregate a Discounted
                              Value at least equal to the Preferred Shares
                              Basic Maintenance Amount and (ii) 1940 Act
                              Preferred Shares Asset Coverage of at least 200%.

See "Description of Preferred Shares--Asset Maintenance."

The Fund estimates that, based on the composition of its portfolio at June 11, 2003, 1940 Act Preferred Shares Asset Coverage would be approximately 286% immediately after the issuance of the Preferred Shares offered hereby in an amount representing approximately 35% of the Fund's capital (including the capital attributable to the Preferred Shares).

The Discount Factors and guidelines for calculating the Discounted Value of the Fund's portfolio for purposes of determining whether the Preferred Shares Basic Maintenance Amount has been satisfied have been established by Moody's and Fitch Ratings in connection with the Fund's receipt of a rating of "Aaa" and "AAA," respectively, on

                              the Preferred Shares on their Date of Original
                              Issue. See "Rating Agency Guidelines."

Mandatory Redemption........  If the Preferred Shares Basic Maintenance Amount
                              or the 1940 Act Preferred Shares Asset Coverage
                              is not maintained or restored as specified
                              herein, the Preferred Shares will be subject to
                              mandatory redemption, out of funds legally
                              available therefor, at the Mandatory Redemption
                              Price of $25,000 per share plus an amount equal
                              to dividends thereon (whether or not earned or
                              declared) accumulated but unpaid to the date
                              fixed for redemption. Any such redemption will be
                              limited to the minimum number of Preferred Shares
                              necessary to restore the Preferred Shares Basic
                              Maintenance Amount or the 1940 Act Preferred
                              Shares Asset Coverage, as the case may be. The
                              Fund's ability to make such a mandatory
                              redemption may be restricted by the provisions of
                              the Investment Company Act of 1940, as amended,
                              and the rules and regulations thereunder (the
                              "1940 Act"). See "Description of Preferred
                              Shares--Redemption--Mandatory Redemption."

Optional Redemption.........  The Preferred Shares are redeemable at the option
                              of the Fund, as a whole or in part, on any
                              Dividend Payment Date (except during the Initial
                              Dividend Period or a Non-Call Period) at the
                              Optional Redemption Price of $25,000 per share,
                              plus an amount equal to dividends thereon
                              (whether or not earned or declared) accumulated
                              but unpaid to the date fixed for redemption plus
                              the premium, if any, resulting from the
                              designation of a Premium Call Period. See
                              "Description of Preferred
                              Shares--Redemption--Optional Redemption."

Liquidation Preference......  The liquidation preference of the Preferred
                              Shares will be $25,000 per share, plus an amount
                              equal to accumulated but unpaid dividends
                              (whether or not earned or declared). See
                              "Description of Preferred Shares--Liquidation
                              Rights."

Rating......................  It is a condition to their issuance that the
                              Preferred Shares be issued with a credit quality
                              rating of "Aaa" from Moody's and "AAA" from Fitch
                              Ratings. The Fund may at some future time seek to
                              have the Preferred Shares rated by a Substitute
                              Rating Agency. See "Rating Agency Guidelines."

Voting Rights...............  The 1940 Act requires that the holders of
                              Preferred Shares and any other preferred shares,
                              voting as a class, have the right to elect at
                              least two trustees at all times and to elect a
                              majority of the trustees at any time when two
                              years' dividends on the Preferred Shares or any
                              other preferred shares are unpaid. The holders of
                              Preferred Shares and any other preferred shares
                              will vote as a separate class (and, in certain
                              circumstances, the holders of each series of
                              Preferred Shares will vote as a separate class)
                              on certain other matters as required under the
                              Declaration and Amended Bylaws and under the 1940
                              Act. See "Description of Preferred Shares--Voting
                              Rights," "Description of Capital Structure" and
                              "Anti-Takeover and Other Provisions in the

Federal Income Taxation.....  The distributions with respect to Preferred
                              Shares (other than distributions in redemption of
                              Preferred Shares subject to Section 302(b) of the
                              Internal Revenue Code of 1986, as amended (the
                              "Code")) will 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. For
                              taxable years beginning on or before December 31,
                              2008, provided holding period and other
                              requirements are met, the Fund may designate
                              distributions of investment income derived from
                              dividends of U.S. corporations and some foreign
                              corporations as "qualified dividend income."
                              Qualified dividend income will be taxed in the
                              hands of individuals at the rates applicable to
                              long-term capital gain, provided these same
                              holding period and other requirements are met by
                              the shareholder. The Fund does not expect a
                              significant portion of Fund distributions to be
                              derived from qualified dividend income.
                              Distributions of net capital gain that are
                              designated by the Fund as capital gain dividends
                              will be treated as long-term capital gains in the
                              hands of holders receiving such distributions.
                              The Internal Revenue Service ("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) based upon the percentage of total
                              dividends distributed to each class for the tax
                              year. Accordingly, the Fund intends each year to
                              allocate capital gain dividends between and among
                              its Common Shares, Series M Preferred Shares,
                              Series T Preferred Shares, Series W Preferred
                              Shares, Series TH Preferred Shares and Series F
                              Preferred Shares in proportion to the total
                              dividends paid to each class during or with
                              respect to such year. Dividends qualifying and
                              not qualifying for (a) treatment as qualified
                              dividend income and (b) the dividends received
                              deduction, if any, will similarly be allocated
                              between and among any such classes. See "Tax

FINANCIAL HIGHLIGHTS (UNAUDITED)

The financial highlights table set forth below is intended to help you understand the Fund's recent financial performance. Information contained in the table below under the headings "Per Share Operating Performance" and "Ratios/Supplemental Data" shows the unaudited operating performance of the Fund from the commencement of the Fund's investment operations on April 30, 2003 through June 1, 2003. Because the Fund is recently organized and commenced investment operations on April 30, 2003, the table covers approximately five weeks 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 operating performance.

THE FUND

The Fund is a recently organized, diversified, closed-end management investment company registered under the 1940 Act. The Fund was organized as a Massachusetts business trust on February 18, 2003, pursuant to the Declaration, which is governed by the laws of The Commonwealth of Massachusetts. The Fund's principal office is located at 1345 Avenue of the Americas, New York, New York 10105, and its telephone number is (800) 331-1710.

The Fund commenced operations on April 30, 2003, upon the closing of an initial public offering of 105,000,000 of its Common Shares. The proceeds of such offering were approximately $1,502,550,000 after the payment of organizational and offering expenses. In connection with the initial public offering of the Fund's Common Shares, the underwriters of those shares were granted an option to purchase up to an additional 10,000,000 Common Shares to cover over-allotments. On May 19, 2003, May 30, 2003, and June 11, 2003, respectively, the underwriters purchased, at a price of $15.00 per Common Share (less an underwriting discount of $0.675 per share), an additional 5,000,000, 2,000,000, and 1,900,000 Common Shares of the Fund, pursuant to the over-allotment option.

USE OF PROCEEDS

The net proceeds of the offering of Preferred Shares will be approximately $890,400,000 after payment of the estimated offering costs (not expected to exceed $600,000). The Fund will invest the net proceeds of the offering in accordance with the Fund's investment objectives and policies as stated below. It is presently anticipated that the Fund will be able to invest substantially all of the net proceeds in U.S. dollar-denominated debt obligations and other investments that meet its investment objectives and policies within three months after the completion of the offering. Pending such investment, it is anticipated that the proceeds will be invested in high quality, short-term securities.

THE FUND'S INVESTMENT OBJECTIVES AND STRATEGIES

Investment Objectives

The Fund's primary investment objective is to seek high current income. Capital appreciation is a secondary objective. Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are, at the time of purchase, rated below investment grade (below Baa by Moody's, below BBB by either S&P or Fitch Ratings, or below a comparable rating by Dominion) or unrated but judged by PIMCO to be of comparable quality. Within this area of the credit spectrum, the Fund will invest in a diversified portfolio of U.S. dollar-denominated debt obligations of varying maturities and other income-producing securities described under "--Portfolio Contents and Other Information" below. The Fund cannot assure you that it will achieve its investment objectives.

Portfolio Management Strategies

In selecting investments for the Fund, PIMCO attempts to identify, through fundamental research, driven by independent credit analysis and proprietary analytical tools, debt obligations and other instruments that provide high current income and/or opportunities for capital appreciation. Investment decisions are based primarily on PIMCO's assessment of the issuer's credit characteristics and the position of the particular security in the issuer's capital structure, in light of PIMCO's outlook for particular industries, the economy and the bond market generally. At the same time, PIMCO uses a variety of techniques, such as credit default swaps, designed to control risk and minimize the Fund's exposure to issues that PIMCO believes are more likely to default or otherwise depreciate in value over time and detract from the Fund's overall return to investors. The Fund cannot assure you that such securities will ultimately continue to pay current income or be paid in full at maturity.

Credit Quality. Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are, at the time of purchase, rated below investment grade (below Baa by Moody's, below BBB by either S&P or Fitch Ratings, or below a comparable rating by Dominion) or unrated but judged by PIMCO to be of comparable quality. While the Fund's relative emphasis on different credit quality segments of the below investment grade credit spectrum may vary over time, PIMCO believes that under current market conditions certain securities in the upper tier of the below investment grade credit spectrum offer opportunities for attractive yield relative to associated risk. Accordingly, the Fund will, under current market conditions, tend to focus on securities that are rated BB/Ba or B by one or more rating agencies or unrated but judged by PIMCO to be of comparable quality. The Fund will not invest more than 10% of its total assets in securities that are, at the time of purchase, rated CCC/Caa or lower by each agency rating the security or unrated but judged by PIMCO to be of comparable quality. The Fund may invest in issuers of any credit quality (including bonds in the lowest ratings categories) if PIMCO determines that the particular obligation is undervalued or offers an attractive yield relative to its risk profile. As described under "--High Yield Securities ("Junk Bonds")" below, debt securities of below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as "junk bonds." The Fund's credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a rating agency or PIMCO downgrades its assessment of the credit characteristics of a particular issue.

The Fund may make use of credit default swaps, although the use of credit default swaps may be limited by the Fund's limitations on illiquid investments. In using a credit default swap contract to hedge exposure to specific issuers, the Fund would pay to a counterparty a periodic stream of payments over the term of the contract, provided that no event of default on a referenced debt obligation of such an issuer, such as a U.S. or foreign issuer, has occurred, and in return, upon any event of default on such debt obligation, the Fund would receive from the counterparty a payment equal to the par (or other agreed-upon) value of such debt obligation.

21

Independent Credit Analysis. PIMCO relies heavily on its own analysis of the credit quality and risks associated with individual debt obligations considered for the Fund, rather than relying exclusively on rating agencies or third-party research. PIMCO has a devoted team of professionals that conducts fundamental credit research and analyses of individual issuers, industries and sectors and uses proprietary analytical tools (such as computer databases and Web-based applications) to assess and monitor credit risk. The individuals managing the Fund utilize this information in an attempt to minimize credit risk and identify issuers, industries or sectors that are undervalued or that offer attractive yields relative to PIMCO's assessment of their credit characteristics. This aspect of PIMCO's capabilities will be particularly important because of the Fund's emphasis on below investment grade securities.

Duration Management. The average portfolio duration of the Fund will normally be within an intermediate range (i.e., a four- to-eight-year time frame) based on PIMCO's forecast for interest rates, although it may be shorter or longer at any time or from time to time depending on market conditions. PIMCO believes that maintaining duration at a fairly stable level within this intermediate range offers the opportunity for above-average returns while limiting exposure to interest rate volatility and related risk.

Duration is a measure of the expected life of a debt security that is used to determine the sensitivity of the security's price to changes in interest rates. The longer a security's duration, the more sensitive it will be to changes in interest rates. For example, the market price of a bond with a duration of two years would be expected to decline 2% if interest rates were to rise 1%. Conversely, the market price of the same bond would be expected to increase 2% if interest rates were to fall 1%. The market price of a bond with a duration of four years would be expected to increase or decline twice as much as the market price of a bond with a two-year duration. The maturity of a security, another commonly used measure of price sensitivity, measures only the time until final payment is due, whereas duration takes into account the pattern of all payments of interest and principal on a security over time, including how these payments are affected by prepayments and by changes in interest rates. The Fund may utilize certain strategies, including investments in structured notes or interest rate swap or cap transactions, for the purpose of reducing the interest rate sensitivity of the portfolio, although there is no assurance that it will do so or that such strategies will be successful.

Portfolio Contents and Other Information

Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are, at the time of purchase, rated below investment grade (below Baa by Moody's, below BBB by either S&P or Fitch Ratings, or below a comparable rating by Dominion) or unrated but judged by PIMCO to be of comparable quality. Within this area of the credit spectrum, the Fund will invest in a diversified portfolio of U.S. dollar-denominated debt obligations of varying maturities and other income-producing securities. These may include bonds, debentures, notes and other similar types of debt instruments, such as asset-backed securities, as well as preferred shares, bank loans and loan participations, commercial mortgage securities, payment-in-kind securities, zero-coupon bonds, bank certificates of deposit, fixed time deposits and bankers' acceptances, structured notes and other hybrid instruments, municipal securities, mortgage-backed securities and other types of asset-backed securities issued on a public or private basis, and real estate investment trusts. The Fund will not invest in interest-only or principal-only securities or inverse floating rate securities. Certain debt instruments, such as convertible bonds, also may include the right to participate in equity appreciation, and PIMCO will generally evaluate those instruments based primarily on their debt characteristics. The Fund may invest in securities of companies with small market capitalizations. The rate of interest on an income-producing security may be fixed, floating or variable. U.S. dollar-denominated debt securities may include those issued by foreign corporations or supra-national government agencies. The principal and/or interest rate on some debt instruments may be determined by reference to the performance of a benchmark asset or market, such as an index of securities, or the differential performance of two assets or markets, such as the level of exchange rates between the U.S. dollar and a foreign currency or currencies.

22

The Fund may also invest in investment grade debt securities, including U.S. Government securities. The Fund may invest up to 15% of its total assets in debt instruments denominated in foreign currencies (of both developed and "emerging market" countries), including obligations of non-U.S. governments and their respective sub-divisions, agencies and government-sponsored enterprises. The Fund may invest without limit in U.S. dollar-denominated securities of issuers located in developed countries, and may invest up to 7.5% of its total assets in securities (regardless of the currency in which such securities are denominated) of issuers located in "emerging market" countries. The Fund also may utilize a variety of derivative instruments for hedging, investment and risk management purposes, such as options contracts (including options on futures contracts), futures contracts, swap agreements (including credit default swaps) and short sales, and may seek to obtain market exposure to the securities in which it primarily invests by entering into a series of purchase and sales contracts. The Fund may invest up to 15% of its total assets in illiquid securities (i.e., securities that cannot be disposed of within seven days in the ordinary course of business at approximately the value at which the Fund has valued the securities). For these purposes, bank loans that are part of an issue of at least $250 million in par value will not be considered illiquid, although the Fund's investments in such bank loans, together with its investments in illiquid securities, will not exceed 20% of its total assets. Given the current structure of the markets for Rule 144A securities, the Fund expects to treat these securities as illiquid, although they may be deemed liquid by PIMCO. Although structured notes are not necessarily illiquid, the Manager believes that currently most structured notes are illiquid. The Manager currently considers credit default swaps to be illiquid and treats the market value of the contract as illiquid for purposes of determining compliance with the Fund's limitations on illiquid investments.

The Fund cannot change its investment objectives without the approval of the holders of a "majority of the outstanding" Common Shares and any Preferred Shares voting together as a single class, and of the holders of a "majority of the outstanding" Preferred Shares voting as a separate class. A "majority of the outstanding" shares (whether voting together as a single class or voting as a separate class) means (i) 67% or more of such shares present at a meeting, if the holders of more than 50% of those shares are present or represented by proxy, or (ii) more than 50% of such shares, whichever is less. See "Description of Preferred Shares--Voting Rights" for additional information with respect to the voting rights of holders of Preferred Shares.

In addition to the issuance of Preferred Shares, the Fund may use a variety of additional strategies to add leverage to the portfolio. These include the use of reverse repurchase agreements, loans of portfolio securities, credit default swap contracts and other derivatives, as well as when-issued, delayed delivery or forward commitment transactions. The Fund will segregate liquid assets against or otherwise cover its future obligations under such transactions to the extent that, immediately after entering into such a transaction, the Fund's future commitments that it has not segregated liquid assets against or otherwise covered, together with any outstanding Preferred Shares, would exceed 38% of the Fund's total assets. The Fund's use of these transactions may also be limited by the Fund's limitations on illiquid investments to the extent they are determined to be illiquid. See "--Derivatives."

Upon PIMCO's recommendation, for temporary defensive purposes and in order to keep the Fund's cash fully invested, including during the period in which the net proceeds of this offering are being invested, the Fund may deviate from its investment objectives and policies and invest some or all of its total assets in investment grade debt securities, including high quality, short-term debt securities. The Fund may not achieve its investment objectives when it does so.

The following provides additional information regarding the types of securities and other instruments in which the Fund will ordinarily invest. A more detailed discussion of these and other instruments and investment techniques that may be used by the Fund is provided under "Investment Objectives and Policies" in the Statement of Additional Information. The ability of the Fund to use some of the strategies discussed below and in the Statement of Additional Information, such as derivatives, is limited by the Rating Agency guidelines.

High Yield Securities ("Junk Bonds")

As noted above, the Fund normally invests at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are, at the time of purchase, rated below investment grade (below Baa by Moody's, below BBB by either S&P or Fitch Ratings, or below a comparable rating by Dominion) or unrated but judged by PIMCO to be of comparable quality. These securities are sometimes referred to as "high yield" securities or "junk bonds." Investing in high yield securities involves greater risks (in particular, greater risk of default) and special risks in addition to the risks associated with investments in investment grade debt obligations. While offering a greater potential opportunity for capital appreciation and higher yields, high yield securities typically entail greater potential price volatility and may be less liquid than higher-rated securities. High yield securities may be regarded as predominantly speculative with respect to the issuer's continuing ability to meet principal and interest payments. They also may be more susceptible to real or perceived adverse economic and competitive industry conditions than higher-rated securities. Debt securities in the lowest investment grade category also may be considered to possess some speculative characteristics.

The market values of high yield securities tend to reflect individual developments of the issuer to a greater extent than do higher-quality securities, which tend to react mainly to fluctuations in the general level of interest rates. In addition, lower-quality debt securities tend to be more sensitive to economic conditions. Certain "emerging market" governments that issue high yield securities are among the largest debtors to commercial banks, foreign governments and supra-national organizations such as the World Bank, and may not be able or willing to make principal and/or interest payments as they come due.

Credit Ratings and Unrated Securities. Rating agencies are private services that provide ratings of the credit quality of debt obligations, including convertible securities. Appendix A to this prospectus describes the various ratings assigned to debt obligations by Moody's, S&P and Fitch Ratings. Ratings assigned by a rating agency are not absolute standards of credit quality and do not evaluate market risks. Rating agencies may fail to make timely changes in credit ratings, and an issuer's current financial condition may be better or worse than a rating indicates. The Fund will not necessarily sell a security when its rating is reduced below its rating at the time of purchase. As described above under "--Portfolio Management Strategies--Independent Credit Analysis," PIMCO does not rely solely on credit ratings, and develops its own analysis of issuer credit quality. The ratings of a debt security may change over time. Moody's, Fitch Ratings, S&P and Dominion monitor and evaluate the ratings assigned to securities on an ongoing basis. As a result, debt instruments held by the Fund could receive a higher rating (which would tend to increase their value) or a lower rating (which would tend to decrease their value) during the period in which they are held.

The Fund may purchase unrated securities (which are not rated by a rating agency) if PIMCO determines that the securities are of comparable quality to rated securities that the Fund may purchase. Unrated securities may be less liquid than comparable rated securities and involve the risk that PIMCO may not accurately evaluate the security's comparative credit rating. Analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher-quality debt obligations. The Fund's success in achieving its investment objectives may depend more heavily on PIMCO's credit analysis than if the Fund invested primarily in higher-quality and rated securities.

Corporate Bonds

The Fund expects to invest in a wide variety of bonds of varying maturities issued by U.S. and foreign corporations and other business entities. Bonds are fixed or variable rate debt obligations, including bills, notes, debentures, money market instruments and similar instruments and securities. Bonds generally are used by corporations as well as governments and other issuers to borrow money from investors. The issuer pays the investor a fixed or variable rate of interest and normally must repay the amount borrowed on or before maturity. Certain bonds are "perpetual" in that they have no maturity date.

24

Credit Default Swaps

The Fund may enter into credit default swap contracts for hedging purposes or to add leverage to the portfolio. When used for hedging purposes, the Fund would be the buyer of a credit default swap contract. In that case, the Fund would be entitled to receive the par (or other agreed-upon) value of a referenced debt obligation from the counterparty to the contract in the event of a default by a third party, such as a U.S. or foreign issuer, on the debt obligation. In return, the Fund would pay to the counterparty a periodic stream of payments over the term of the contract, provided that no event of default has occurred. If no default occurs, the Fund would have spent the stream of payments and received no benefit from the contract. When the Fund is the seller of a credit default swap contract, it receives the stream of payments but is obligated to pay upon default of the referenced debt obligation. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total assets, the Fund would be subject to investment exposure on the notional amount of the swap. The Manager currently considers credit default swaps to be illiquid and treats the market value of the contract as illiquid for purposes of determining compliance with the Fund's limitations on illiquid investments.

Commercial Paper

Commercial paper represents short-term unsecured promissory notes issued in bearer form by corporations such as banks or bank holding companies and finance companies. The rate of return on commercial paper may be linked or indexed to the level of exchange rates between the U.S. dollar and a foreign currency or currencies.

Preferred Stocks

Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stocks, dividends and a fixed share of the proceeds resulting from liquidation of the company. Some preferred stocks also entitle their holders to receive additional liquidation proceeds on the same basis as holders of a company's common stock, and thus also represent an ownership interest in the company. Some preferred stocks offer a fixed rate of return with no maturity date. Because they never mature, these preferred stocks act like long-term bonds, can be more volatile than other types of preferred stocks and may have heightened sensitivity to changes in interest rates. Other preferred stocks have a variable dividend, generally determined on a quarterly or other periodic basis, either according to a formula based upon a specified premium or discount to the yield on particular U.S. Treasury securities or based on an auction process, involving bids submitted by holders and prospective purchasers of such stocks. Because preferred stocks represent an equity ownership interest in a company, their value usually will react more strongly than bonds and other debt instruments to actual or perceived changes in a company's financial condition or prospects, or to fluctuations in the equity markets.

Convertible Securities and Synthetic Convertible Securities

The Fund may invest in convertible securities, which are debt securities that may be converted at either a stated price or a stated rate into underlying shares of common stock. Convertible securities have general characteristics similar to both debt securities and equity securities. PIMCO will generally evaluate these instruments based primarily on their debt characteristics. Although to a lesser extent than with debt obligations, the market value of convertible securities tends to decline as interest rates increase and, conversely, tends to increase as interest rates decline. In addition, because of the conversion feature, the market value of convertible securities tends to vary with fluctuations in the market value of the underlying common stocks and, therefore, also will react to variations in the general market for equity securities.

Convertible securities are investments that provide for a stable stream of income with generally higher yields than common stocks. There can be no assurance of current income because the issuers of the convertible securities may default on their obligations. Convertible securities, however, generally offer lower interest or dividend yields than non-convertible securities of similar credit quality because of the potential for capital

25

appreciation. A convertible security, in addition to providing current income, offers the potential for capital appreciation through the conversion feature, which enables the holder to benefit from increases in the market price of the underlying common stock.

Synthetic convertible securities differ from convertible securities in certain respects. Unlike a true convertible security, which is a single security having a unitary market value, a synthetic convertible comprises two or more separate securities, each with its own market value. Therefore, the "market value" of a synthetic convertible security is the sum of the values of its debt component and its convertibility component. For this reason, the values of a synthetic convertible and a true convertible security may respond differently to market fluctuations.

Bank Obligations

The Fund may invest in certain bank obligations, including certificates of deposit, bankers' acceptances, and fixed time deposits. Certificates of deposit are negotiable certificates issued against funds deposited in a commercial bank for a definite period of time and earning a specified return. Bankers' acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are "accepted" by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties which vary depending upon market conditions and the remaining maturity of the obligation.

Loan Participations and Assignments

The Fund may invest in fixed- and floating-rate loans issued by banks and other corporations, which investments generally will be in the form of loan participations and assignments of portions of such loans. Participations and assignments involve credit risk, interest rate risk, liquidity risk, and the risks of being a lender. If the Fund purchases a participation, it may only be able to enforce its rights through the lender, and may assume the credit risk of both the lender and the borrower. Given the current structure of the markets for loan participations and assignments, the Fund expects to treat these securities as illiquid.

Zero-Coupon Bonds, Step-Ups and Payment-In-Kind Securities

Zero-coupon bonds pay interest only at maturity rather than at intervals during the life of the security. Like zero-coupon bonds, "step up" bonds pay no interest initially but eventually begin to pay a coupon rate prior to maturity, which rate may increase at stated intervals during the life of the security. Payment-in-kind securities ("PIKs") are debt obligations that pay "interest" in the form of other debt obligations, instead of in cash. Each of these instruments is normally issued and traded at a deep discount from face value. Zero-coupon bonds, step-ups and PIKs allow an issuer to avoid or delay the need to generate cash to meet current interest payments and, as a result, may involve greater credit risk than bonds that pay interest currently or in cash. The Fund would be required to distribute the income on these instruments as it accrues, even though the Fund will not receive the income on a current basis or in cash. Thus, the Fund may have to sell other investments, including when it may not be advisable to do so, to make income distributions to its shareholders.

Foreign (Non-U.S.) Investments and Currencies

The Fund may invest some or all of its assets in U.S. dollar-denominated debt obligations of foreign issuers and of supra-national government entities. Supra-national entities include international organizations that are organized or supported by one or more government entities to promote economic reconstruction or development and by international banking institutions and related governmental agencies. The Fund also may invest up to 15% of its total assets in debt instruments denominated in foreign currencies (of both developed and "emerging

26

market" countries), including obligations of non-U.S. governments and their respective sub-divisions, agencies and government-sponsored enterprises. The Fund may invest up to 7.5% of its total assets in securities (regardless of the currency in which such securities are denominated) of issuers located in "emerging market" countries. Investing in foreign securities involves special risks and considerations not typically associated with investing in U.S. securities. See "Risks--Foreign (Non-U.S.) Investment Risk."

The U.S. dollar-denominated foreign securities in which the Fund may invest include Eurodollar obligations and "Yankee Dollar" obligations. Eurodollar obligations are U.S. dollar-denominated certificates of deposit and time deposits issued outside the U.S. capital markets by foreign branches of U.S. banks and by foreign banks. Yankee Dollar obligations are U.S. dollar-denominated obligations issued in the U.S. capital markets by foreign banks. Eurodollar and Yankee Dollar obligations are generally subject to the same risks that apply to domestic debt issues, notably credit risk, market risk and liquidity risk. Additionally, Eurodollar (and to a limited extent, Yankee Dollar) obligations are subject to certain sovereign risks. One such risk is the possibility that a sovereign country might prevent capital, in the form of U.S. dollars, from flowing across its borders. Other risks include adverse political and economic developments; the extent and quality of government regulation of financial markets and institutions; the imposition of foreign withholding taxes; and the expropriation or nationalization of foreign issuers.

The Fund also may invest in sovereign debt issued by foreign governments, their agencies or instrumentalities, or other government-related entities, including debt of developing or "emerging market" issuers. As a holder of sovereign debt, the Fund may be requested to participate in the rescheduling of such debt and to extend further loans to governmental entities. In addition, there are generally no bankruptcy proceedings similar to those in the United States by which defaulted sovereign debt may be collected. The Fund also may invest in Brady Bonds, which are securities created through the exchange of existing commercial bank loans to sovereign entities for new obligations in connection with a debt restructuring. Investments in Brady Bonds may be viewed as speculative. Brady Bonds acquired by the Fund may be subject to restructuring arrangements or to requests for new credit, which may cause the Fund to realize a loss of interest or principal on any of its portfolio holdings.

Foreign Currencies and Related Transactions. The Fund's investments in securities that trade in, or receive revenues in, foreign currencies will be subject to currency risk, which is the risk that fluctuations in the exchange rates between the U.S. dollar and foreign currencies may negatively affect any investment. The Fund may engage in a variety of transactions involving foreign currencies in order to hedge against foreign currency risk, to increase exposure to a foreign currency, or to shift exposure to foreign currency fluctuations from one currency to another. For instance, the Fund may purchase foreign currencies on a spot (cash) basis and enter into forward foreign currency exchange contracts, foreign currency futures contracts and options on foreign currencies and futures. The Fund normally will seek to hedge at least 75% of its exposure to foreign currencies in order to reduce the risk of loss due to fluctuations in currency exchange rates. Suitable hedging transactions may not be available in all circumstances, and there can be no assurance that the Fund will engage in such transactions at any given time or from time to time. Also, these transactions may not be successful and may eliminate any chance for the Fund to benefit from favorable fluctuations in relevant foreign currencies.

Please see "Investment Objectives and Policies--Foreign (Non-U.S.) Securities," "Investment Objectives and Policies--Foreign Currency Transactions" and "Investment Objectives and Policies--Foreign Currency Exchange-Related Securities" in the Statement of Additional Information for a more detailed description of the types of foreign investments and foreign currency transactions in which the Fund may invest and their related risks.

Derivatives

The Fund may, but is not required to, use a variety of derivative instruments for hedging or risk management purposes or as part of its investment strategies. The Fund may invest in derivatives without limit for

27

hedging purposes, and may invest up to 25% (10% within 90 days of the date of the prospectus for the Common Shares, which was April 24, 2003) of its total assets in derivatives for non-hedging purposes. For these purposes, "hedging purposes" include the use of a derivative instrument to cause the Fund to more closely resemble the Merrill Lynch U.S. High Yield BB-B Rated Index with respect to credit quality, average portfolio duration, and/or average portfolio yield-to-maturity. Generally, derivatives are financial contracts whose value depends upon, or is derived from, the value of an underlying asset, reference rate or index, and may relate to individual debt instruments, interest rates, currencies or currency exchange rates, commodities, and related indexes. Examples of derivative instruments that the Fund may use include options contracts, futures contracts, options on futures contracts and swap agreements. The Fund's use of derivative instruments involves risks different from, or possibly greater than, the risks associated with investment directly in securities and other more traditional investments. See "Risks--Derivatives Risk." Certain types of derivative instruments that the Fund may utilize with some frequency are described elsewhere in this section, including those described under "--Certain Interest Rate Transactions," "--Structured Notes and Related Instruments" and "--Credit Default Swaps." Please see "Investment Objectives and Policies--Derivative Instruments" in the Statement of Additional Information for additional information about these and other derivative instruments that the Fund may use and the risks associated with such instruments. There is no assurance that these derivative strategies will be available at any time or that PIMCO will determine to use them for the Fund or, if used, that the strategies will be successful. In addition, the Fund may be subject to certain restrictions on its use of derivative strategies imposed by guidelines of one or more rating agencies that may issue ratings for Preferred Shares issued by the Fund.

Commercial and Other Mortgage-Related and Asset-Backed Securities

Mortgage-related securities are debt instruments which provide periodic payments consisting of interest and/or principal that are derived from or related to payments of interest and/or principal on underlying mortgages. Additional payments on mortgage-related securities may be made out of unscheduled prepayments of principal resulting from the sale of the underlying property or from refinancing or foreclosure, net of fees or costs that may be incurred.

The Fund may invest significantly in commercial mortgage-related securities issued by corporations. These are securities that represent an interest in, or are secured by, mortgage loans secured by commercial property, such as industrial and warehouse properties, office buildings, retail space and shopping malls, multifamily properties and cooperative apartments, hotels and motels, nursing homes, hospitals, and senior living centers. They may pay fixed or adjustable rates of interest. The commercial mortgage loans that underlie commercial mortgage-related securities have certain distinct risk characteristics. Commercial mortgage loans generally lack standardized terms, which may complicate their structure. Commercial properties themselves tend to be unique and difficult to value. Commercial mortgage loans tend to have shorter maturities than residential mortgage loans, and may not be fully amortizing, meaning that they may have a significant principal balance, or "balloon" payment, due on maturity. In addition, commercial properties, particularly industrial and warehouse properties, are subject to environmental risks and the burdens and costs of compliance with environmental laws and regulations.

Other mortgage-related securities in which the Fund may invest include mortgage pass-through securities, collateralized mortgage obligations ("CMOs"), mortgage dollar rolls and other securities that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property.

The Fund may invest in other types of asset-backed securities that are offered in the marketplace, including Enhanced Equipment Trust Certificates ("EETCs") and collateralized debt obligations ("CDOs"). Although any entity may issue EETCs, to date, U.S. airlines are the primary issuers. An airline EETC is an obligation secured directly by aircraft or aircraft engines as collateral. EETCs tend to be less liquid than bonds. CDOs include collateralized bond obligations ("CBOs"), collateralized loan obligations ("CLOs") and other similarly structured securities. A CBO is a trust typically backed by a diversified pool of high-risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others,

28

domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans. While the trusts that issue CDOs may themselves be leveraged and may invest in credits that are lower than what the Fund can invest in directly, the Fund will generally purchase only senior CDOs, will not purchase residual CDOs and will only purchase CDOs that meet the Fund's credit policies.

Other asset-backed securities may be collateralized by the fees earned by service providers. The value of asset-backed securities may be substantially dependent on the servicing of the underlying asset pools and are therefore subject to risks associated with the negligence of, or defalcation by, their servicers. In certain circumstances, the mishandling of related documentation may also affect the rights of the security holders in and to the underlying collateral. The insolvency of entities that generate receivables or that utilize the assets may result in added costs and delays in addition to losses associated with a decline in the value of the underlying assets. The issuers of certain asset-backed securities bear various expenses, including, without limitation, servicing and advisory fees.

Please see "Investment Objectives and Policies--Mortgage-Related and Other Asset-Backed Securities" in the Statement of Additional Information and "Risks--Mortgage-Related Risk" in this prospectus for a more detailed description of the types of mortgage-related and other asset-backed securities in which the Fund may invest and their related risks.

Variable and Floating Rate Securities

Variable and floating rate securities provide for a periodic adjustment in the interest rate paid on the obligations. The Fund may invest in floating rate debt instruments ("floaters") and engage in credit spread trades. While floaters provide a certain degree of protection against rising interest rates, the Fund will participate in any decline in interest rates as well. A credit spread trade is an investment position relating to a difference in the prices or interest rates of two bonds or other securities, where the value of the investment position is determined by changes in the difference between such prices or interest rates, as the case may be, of the respective securities.

Delayed Funding Loans and Revolving Credit Facilities

The Fund may enter into, or acquire participations in, delayed funding loans and revolving credit facilities, in which a lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. These commitments may have the effect of requiring the Fund to increase its investment in a company at a time when it might not be desirable to do so (including at a time when the company's financial condition makes it unlikely that such amounts will be repaid). Delayed funding loans and revolving credit facilities are subject to credit, interest rate and liquidity risk and the risks of being a lender.

Certain Interest Rate Transactions

In order to reduce the interest rate risk inherent in the Fund's underlying investments and capital structure, the Fund may 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's paying the Fund a variable rate payment that is intended to approximate the Fund's variable rate payment obligation on Preferred Shares. The payment obligation would be based on the notional amount of the swap. The Fund may use an interest rate cap, which would require the Fund to pay a premium to the cap counterparty and would entitle the Fund, 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 may use interest rate swaps or caps with the intent to reduce or eliminate the risk that an increase in short-term interest rates could pose for the performance of the Common Shares as a result of leverage, and also may use these instruments for other hedging or investment purposes. The Fund may choose or be required to redeem some or all of the Preferred Shares. This redemption would likely result in the Fund's seeking to terminate early all or a portion of any swap or cap

29

transaction. Such early termination of a swap could result in a termination payment by or to the Fund. Any termination of a cap could result in a termination payment to the Fund.

Structured Notes and Related Instruments

The Fund may invest in "structured" notes and other related instruments, which are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate (an "embedded index"), such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets, such as indexes reflecting bonds. Structured instruments may be issued by corporations, including banks, as well as by governmental agencies. Structured instruments frequently are assembled in the form of medium-term notes, but a variety of forms are available and may be used in particular circumstances. The terms of such structured instruments normally provide that their principal and/or interest payments are to be adjusted upwards or downwards (but ordinarily not below zero) to reflect changes in the embedded index while the structured instruments are outstanding. As a result, the interest and/or principal payments that may be made on a structured product may vary widely, depending on a variety of factors, including the volatility of the embedded index and the effect of changes in the embedded index on principal and/or interest payments. The rate of return on structured notes may be determined by the application of a multiplier to the performance or differential performance of the referenced index(es) or other asset(s). Application of a multiplier involves leverage that will serve to magnify the potential for gain and the risk of loss.

PIMCO may utilize structured instruments for investment purposes and also for risk management purposes, such as to reduce the duration and interest rate sensitivity of the Fund's portfolio. While structured instruments may offer the potential for a favorable rate of return from time to time, they also entail certain risks. Structured instruments may be less liquid than other debt securities, and the price of structured instruments may be more volatile. In some cases, depending on the terms of the embedded index, a structured instrument may provide that the principal and/or interest payments may be adjusted below zero. Structured instruments also may involve significant credit risk and risk of default by the counterparty. Although structured instruments are not necessarily illiquid, the Manager believes that currently most structured instruments are illiquid. Like other sophisticated strategies, the Fund's use of structured instruments may not work as intended. If the value of the embedded index changes in a manner other than that expected by PIMCO, principal and/or interest payments received on the structured instrument may be substantially less than expected. Also, if PIMCO uses structured instruments to reduce the duration of the Fund's portfolio, this may limit the Fund's return when having a longer duration would be beneficial (for instance, when interest rates decline).

Reverse Repurchase Agreements

The Fund may utilize reverse repurchase agreements in order to add leverage to the portfolio. In a reverse repurchase agreement, the Fund sells securities to a bank or broker-dealer and agrees to repurchase the securities at a mutually agreed date and price. Generally, the effect of such a transaction is that the Fund can recover and reinvest all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement and still be entitled to the returns associated with those portfolio securities. Such transactions are advantageous if the interest cost to the Fund of the reverse repurchase transaction is less than the returns it obtains on investments purchased with the cash.

Unless the Fund covers its positions in reverse repurchase agreements (by segregating liquid assets at least equal in amount to the forward purchase commitment), its obligations under the agreements will be subject to the Fund's limitations on borrowings. Reverse repurchase agreements involve leverage risk and also the risk that the market value of the securities that the Fund is obligated to repurchase under the agreement may decline below the repurchase price. In the event the buyer of securities under a reverse repurchase agreement files for bankruptcy or becomes insolvent, the Fund's use of the proceeds of the agreement may be restricted pending a determination by the other party, or its trustee or receiver, whether to enforce the Fund's obligation to repurchase the securities.

30

Repurchase Agreements

The Fund may enter into repurchase agreements, in which the Fund purchases a security from a bank or broker-dealer and the bank or broker-dealer agrees to repurchase the security at the Fund's cost plus interest within a specified time. If the party agreeing to repurchase should default, the Fund will seek to sell the securities which it holds. This could involve transaction costs or delays in addition to a loss on the securities if their value should fall below their repurchase price. Repurchase agreements maturing in more than seven days are considered to be illiquid securities.

U.S. Government Securities

The Fund may invest in U.S. Government securities, which are obligations of, or guaranteed by, the U.S. Government, its agencies or government-sponsored enterprises. U.S. Government securities include a variety of securities that differ in their interest rates, maturities and dates of issue. Securities issued or guaranteed by agencies or instrumentalities of the U.S. Government may or may not be supported by the full faith and credit of the United States or by the right of the issuer to borrow from the U.S. Treasury.

Municipal Bonds

Municipal bonds are generally issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities. Like other debt obligations, municipal bonds are subject to interest rate, credit and market risk. The ability of a municipal issuer to make payments could be affected by litigation, legislation or other political events or the bankruptcy of the issuer. The types of municipal bonds in which the Fund may invest include municipal lease obligations. The Fund also may invest in securities issued by entities whose underlying assets are municipal bonds.

When Issued, Delayed Delivery and Forward Commitment Transactions

The Fund may purchase securities which it is eligible to purchase on a when-issued basis, may purchase and sell such securities for delayed delivery and may make contracts to purchase such securities for a fixed price at a future date beyond normal settlement time (forward commitments). When-issued transactions, delayed delivery purchases and forward commitments involve a risk of loss if the value of the securities declines prior to the settlement date. This risk is in addition to the risk that the Fund's other assets will decline in value. Therefore, these transactions may result in a form of leverage and increase the Fund's overall investment exposure. Typically, no income accrues on securities the Fund has committed to purchase prior to the time delivery of the securities is made, although the Fund may earn income on securities it has segregated to cover these positions.

Short Sales

A short sale is a transaction in which the Fund sells an instrument that it does not own in anticipation that the market price will decline. The Fund may use short sales for investment and risk management purposes. When the Fund engages in a short sale, it must borrow the security sold short and deliver it to the counterparty. The Fund may have to pay a fee to borrow particular securities and would often be obligated to pay over any payments received on such borrowed securities. The Fund's obligation to replace the borrowed security will be secured by collateral deposited with the lender, which is usually a broker-dealer, and/or with the Fund's custodian. The Fund may not receive any payments (including interest) on its collateral. Short sales expose the Fund to the risk that it will be required to cover its short position at a time when the securities have appreciated in value, thus resulting in a loss to the Fund. The Fund may engage in so-called "naked" short sales where it does not own or have the immediate right to acquire the security sold short at no additional cost, in which case the Fund's losses could theoretically be unlimited, provided that the Fund will not engage in such naked short sales in excess of 5% of the Fund's total assets and that the Fund will not engage in any such naked short sales within 90 days from the date of the prospectus for the Common Shares, which was April 24, 2003.

RISKS

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 even that you may lose part or all of your investment. Therefore, before purchasing Preferred Shares, you should consider carefully the following risks that you assume when you invest in the Fund.

Risks of Investing in Preferred Shares

Auction Risk

You may not be able to sell your Preferred Shares at an Auction if the Auction fails; that is, if there are more Preferred Shares offered for sale than there are buyers for those shares. If Sufficient Clearing Bids do not exist in an Auction, the Applicable Rate will be the Maximum Applicable Rate, and in such event, owners of Preferred Shares wishing to sell will not be able to sell all, and may not be able to sell any, of such shares in the Auction. As a result, your investment in Preferred Shares may be illiquid. Neither the Broker-Dealers nor the Fund is obligated to purchase Preferred Shares in an Auction or otherwise, nor is the Fund required to redeem Preferred Shares in the event of a failed Auction. Also, if you place bid orders (orders to retain Preferred Shares) at an Auction only at a specified rate, and that bid rate exceeds the Applicable Rate set at the Auction, you will not retain your Preferred Shares. Finally, if you elect to retain Preferred Shares without specifying a rate below which you would not wish to continue to hold those Preferred Shares, and the Auction sets a below-market rate, you may receive a lower rate of return on your Preferred Shares than the market rate. See "Description of Preferred Shares--The Auction" and "Description of Preferred Shares--Auction Procedures."

Ratings and Asset Coverage Risk

While Moody's is expected to assign a rating of "Aaa" to the Preferred Shares and Fitch Ratings is expected to assign a rating of "AAA" to the Preferred Shares, the ratings will not eliminate or necessarily mitigate the risks of investing in the Preferred Shares. A Rating Agency could downgrade the Preferred Shares, which may make your shares less liquid at an Auction or in the secondary market. In addition, the Fund may be forced to redeem your Preferred Shares to meet regulatory or Rating Agency requirements. The Fund may also voluntarily redeem Preferred Shares under certain circumstances. See "Description of Preferred Shares--Redemption." The Fund may not redeem Preferred Shares if such a redemption would cause the Fund to fail to meet regulatory or Rating Agency asset coverage requirements, and the Fund may not declare, pay or set apart for payment any dividend or other distribution if immediately thereafter the Fund would fail to meet regulatory asset coverage requirements. A material decline in the Fund's net asset value may impair the Fund's ability to maintain its required levels of asset coverage on the Preferred Shares, or, in an extreme case, to pay dividends on Preferred Shares. In addition, as a condition to its receipt of "Aaa" and "AAA" ratings on the Preferred Shares, the Fund has agreed to certain investment limitations, which may restrict the Fund from making investments that PIMCO believes would benefit the Fund. See "Rating Agency Guidelines" for descriptions of the significance and limitations of the ratings on the Preferred Shares and of the asset maintenance and other tests the Fund must meet.

Secondary Market Risk

The Broker-Dealers may maintain a secondary trading market in the Preferred Shares outside of Auctions; however, they have no obligation to do so, and there can be no assurance that a secondary market for the Preferred Shares will develop or, if it does develop, that it will provide holders with a liquid trading market (i.e., trading will depend on the presence of willing buyers and sellers, and the trading price is subject to variables to

32

be determined at the time of the trade by the Broker-Dealers). The Preferred Shares will not be registered on any stock exchange or on any automated quotation system. 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 receive a purchase price of less than $25,000 per share. An increase in the level of interest rates, particularly during any Long Term Dividend Period, likely will have an adverse effect on the secondary market price of the Preferred Shares.

General Risks of Investing in the Fund

Limited Operating History

The Fund is a recently organized, diversified, closed-end management investment company which has been operational for less than two months.

High Yield Risk

In general, lower rated debt securities carry a greater degree of risk that the issuer will lose its ability to make interest and principal payments, which could have a negative impact on the Fund's net asset value or dividends. Under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (plus any borrowings for investment purposes) in debt securities that are, at the time of purchase, rated below investment grade (below Baa by Moody's, below BBB by either S&P or Fitch Ratings or below a comparable rating by Dominion) or unrated but judged by PIMCO to be of comparable quality, including debt securities that are in default or the issuers of which are in bankruptcy. Debt securities rated below investment grade quality are regarded as having predominantly speculative characteristics with respect to capacity to pay interest and repay principal, and are commonly referred to as "junk bonds." The prices of these lower grade bonds are generally more volatile and sensitive to actual or perceived negative developments, such as a decline in the issuer's revenues or a general economic downturn, than are the prices of higher grade securities. In addition, the secondary market on which high yield securities are traded may be less liquid than the market for investment grade securities, meaning these securities are subject to greater liquidity risk than investment grade securities. Bonds in the lowest investment grade category also may be considered by certain rating agencies to possess some speculative characteristics. Because of the Fund's emphasis on below investment grade debt obligations, PIMCO's capabilities in this area will be particularly important.

High yield securities may be more susceptible to real or perceived adverse economic and competitive industry conditions than investment grade securities. A projection of an economic downturn or of a period of rising interest rates, for example, could cause a decline in high yield security prices because the advent of a recession could lessen the ability of an issuer to make principal and interest payments on its debt obligations. If an issuer of high yield securities defaults, in addition to risking non-payment of all or a portion of interest and principal, the Fund may incur additional expenses to seek recovery. The market prices of high yield securities structured as zero-coupon, step-up or payment-in-kind securities will normally be affected to a greater extent by interest rate changes, and therefore tend to be more volatile than the prices of securities that pay interest currently and in cash. PIMCO seeks to reduce these risks through diversification, credit analyses and attention to current developments and trends in both the economy and financial markets.

The Fund's credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a rating agency or PIMCO downgrades its assessment of the credit characteristics of a particular issue. In determining whether to retain or sell such a security, PIMCO may consider such factors as PIMCO's assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. Analysis of creditworthiness may be more complex for issuers of high yield securities than for issuers of higher quality debt securities.

Credit Risk

The Fund could lose money if the issuer of a debt obligation, or the counterparty to a derivatives contract, repurchase agreement, loan of portfolio securities or other obligation, is, or is perceived to be, unable or unwilling to make timely principal and/or interest payments, or to otherwise honor its obligations. The downgrade of a security may further decrease its value.

Interest Rate Risk

Interest rate risk is the risk that debt obligations (and the Fund's total assets) will decline in value because of changes in interest rates. Generally, debt securities will decrease in value when interest rates rise and increase in value when interest rates decline. This means that the Fund's net asset value will fluctuate with interest rate changes and the corresponding changes in the value of the Fund's holdings. Because market interest rates are currently near their lowest levels in many years, there is a great risk that the Fund's portfolio will decline in value. The prices of long-term debt obligations generally fluctuate more than prices of short-term debt obligations as interest rates change. Because the Fund will normally have an intermediate portfolio duration (i.e., a four- to -eight-year time frame), the Fund's net asset value will tend to fluctuate more in response to changes in market interest rates than if the Fund invested mainly in short-term debt securities. The Fund may utilize certain strategies, including investments in structured notes and interest rate swaps and caps, for the purpose of reducing the interest rate sensitivity of the portfolio and decreasing the Fund's exposure to interest rate risk, although there is no assurance that it will do so or that such strategies will be successful. The Fund's use of leverage, as described below, will tend to increase interest rate risk. If long-term rates rise, the value of the Fund's investment portfolio may decline, reducing asset coverage on the Preferred Shares. See "How the Fund Manages Risk--Hedging and Related Strategies."

Leverage Risk

The Fund utilizes leverage on an ongoing basis for investment purposes. Leverage risk includes the risk associated with the issuance of the Preferred Shares or the use of reverse repurchase agreements, loans of portfolio securities, credit default swap contracts and other derivatives, as well as when-issued, delayed delivery or forward commitment transactions, in order to leverage the Common Shares. If the dividend rate on the Preferred Shares exceeds the net rate of return on the Fund's portfolio, the leverage will result in a lower net asset value than if the Fund were not leveraged, and the Fund's ability to pay dividends and meet its asset coverage requirements on the Preferred Shares would be reduced. Because the longer-term bonds included in the Fund's portfolio will typically pay fixed rates of interest while the dividend rate on the Preferred Shares will be adjusted periodically, this could occur even when both long-term and short-term interest rates rise. Similarly, any decline in the net asset value of the Fund's investments could result in the Fund being in danger of failing to meet its asset coverage requirements or of losing its expected "Aaa" and "AAA" ratings on the Preferred Shares or, in an extreme case, the Fund's current investment income might not be sufficient to meet the dividend requirements on the Preferred Shares. In order to counteract such an event, the Fund might need to liquidate investments in order to fund a redemption of some or all of the Preferred Shares. In addition, to the extent that any forms of leverage utilized by the Fund are senior to the Preferred Shares, payments to holders of Preferred Shares in liquidation or otherwise will be subject to the prior payment of obligations relating to such other forms of leverage.

While the Fund may from time to time consider reducing leverage in response to actual or anticipated changes in interest rates in an effort to mitigate the increased volatility of current income and net asset value associated with leverage, there can be no assurance that the Fund will actually reduce leverage in the future or that any reduction, if undertaken, will be effective. Changes in the future direction of interest rates are very difficult to predict accurately. If the Fund were to reduce leverage based on a prediction about future changes to interest rates, and that prediction turned out to be incorrect, the reduction in leverage would likely operate to reduce the Fund's net asset value relative to the circumstance where the Fund had not reduced leverage. The

34

Fund may decide that this risk outweighs the likelihood of achieving the desired reduction to volatility in income and net asset value if the prediction were to turn out to be correct, and determine not to reduce leverage as described above.

Because the fees received by the Manager are based on the total net assets of the Fund, the fees will be higher when leverage is utilized through the issuance of Preferred Shares, giving the Manager and PIMCO an incentive to utilize such leverage.

Issuer Risk

The value of income-producing securities may decline for a number of reasons which directly relate to the issuer, such as management performance, financial leverage and reduced demand for the issuer's goods and services.

Management Risk

The Fund is subject to management risk because it is an actively managed investment portfolio. PIMCO and the individual portfolio managers will apply investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these will produce the desired results.

Foreign (Non-U.S.) Investment Risk

The Fund may invest some or all of its assets in U.S. dollar-denominated debt obligations of foreign issuers or supra-national government agencies. The Fund also may invest up to 15% of its total assets in debt instruments denominated in foreign currencies (of both developed and "emerging market" countries), including obligations of non-U.S. governments and their respective sub-divisions, agencies and government-sponsored enterprises. The Fund may invest up to 7.5% of its total assets in securities (regardless of the currency in which such securities are denominated) of issuers located in "emerging market" countries. The Fund's investments in foreign issuers and in securities denominated in foreign currencies involve special risks. There may be less information publicly available about a foreign issuer than about a U.S. issuer, and foreign issuers are not generally subject to accounting, auditing and financial reporting standards and practices comparable to those in the United States. The securities of some foreign issuers are less liquid and at times more volatile than securities of comparable U.S. issuers. Foreign brokerage costs, custodial expenses and other fees are also generally higher than for securities traded in the United States. With respect to certain foreign countries, there is also a possibility of expropriation of assets, confiscatory taxation, political or financial instability and diplomatic developments which could affect the value of investments in those countries. In addition, income received by the Fund from sources within foreign countries may be reduced by withholding and other taxes imposed by such countries.

The value of securities denominated in foreign currencies may fluctuate based on changes in the value of those currencies relative to the U.S. dollar, and a decline in applicable foreign exchange rates could reduce the value of such securities held by the Fund. The values of foreign investments and the investment income derived from them also may be affected unfavorably by changes in currency exchange control regulations. In addition, although a portion of the Fund's investment income may be received or realized in foreign currencies, the Fund will be required to compute and distribute its income in U.S. dollars. Therefore, if the exchange rate for any such currency declines after the Fund's income has been earned and translated into U.S. dollars but before payment, the Fund could be required to liquidate portfolio securities to make such distributions.

Emerging Markets Risk

The Fund may invest up to 7.5% of its total assets in securities (regardless of the currency in which such securities are denominated) of issuers located in "emerging market" countries. Investing in securities of issuers based in underdeveloped emerging markets entails all of the risks of investing in securities of foreign issuers to a

35

heightened degree. These heightened risks include: (i) greater risks of expropriation, confiscatory taxation, nationalization, and less social, political and economic stability; (ii) the smaller size of the market for such securities and a lower volume of trading, resulting in lack of liquidity and in price volatility; and (iii) certain national policies which may restrict the Fund's investment opportunities, including restrictions on investing in issuers or industries deemed sensitive to relevant national interests.

Derivatives Risk

The Fund may use a variety of derivative instruments for hedging or risk management purposes or as part of its leveraging or investment strategies. The Fund may invest in derivatives without limit for hedging purposes, and may invest up to 25% (10% within 90 days of the date of the prospectus for the Common Shares, which was April 24, 2003) of its total assets in derivatives for non-hedging purposes. For these purposes, "hedging purposes" include the use of a derivative instrument to cause the Fund to more closely resemble the Merrill Lynch U.S. High Yield BB-B Rated Index with respect to credit quality, average portfolio duration, and/or average portfolio yield-to-maturity. Derivatives are financial contracts whose value depends on, or is derived from, the value of an underlying asset, reference rate or index (or relationship between two indexes). The Fund may invest in a variety of derivative instruments, for hedging or risk management purposes or as part of its investment strategies, such as options contracts (including options on futures contracts), futures contracts, swap agreements (including credit default swaps) and short sales. The Fund may use derivatives as a substitute for taking a position in an underlying debt instrument or other asset and/or as part of a strategy designed to reduce exposure to other risks, such as interest rate or currency risk. The Fund also may use derivatives to add leverage to the portfolio. The Fund's use of derivative instruments involves risks different from, and possibly greater than, the risks associated with investing directly in securities and other traditional investments. Derivatives are subject to a number of risks described elsewhere in this prospectus, such as liquidity risk, interest rate risk, credit risk, leveraging risk and management risk. They also involve the risk of mispricing or improper valuation, the risk of ambiguous documentation and the risk that changes in the value of the derivative may not correlate perfectly with the underlying asset, rate or index. If the Fund invests in a derivative instrument, it could lose more than the principal amount invested. Also, suitable derivative transactions may not be available in all circumstances, and there can be no assurance that the Fund will engage in these transactions to reduce exposure to other risks when that would be beneficial. In addition, the Fund may be subject to certain restrictions on its use of derivative strategies imposed by guidelines of one or more Rating Agencies. The use of derivatives also may increase the amount of taxes payable by shareholders. In addition to the risks applicable to derivatives generally, credit default swaps involve special risks because they are difficult to value, are highly susceptible to liquidity and credit risk, and generally pay a return to the party that has paid the premium only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial difficulty).

Counterparty Risk

The Fund will be subject to credit risk with respect to the counterparties to the derivative contracts purchased by the Fund. If a counterparty becomes bankrupt or otherwise fails to perform its obligations under a derivative contract because of financial difficulties, the Fund may experience significant delays in obtaining any recovery under the derivative contract in a bankruptcy or other reorganization proceeding. The Fund may obtain only a limited recovery or may obtain no recovery in such circumstances.

Mortgage-Related Risk

The Fund may invest in a variety of mortgage-related securities, including commercial mortgage securities and other mortgage-backed instruments. Rising interest rates tend to extend the duration of mortgage-related securities, making them more sensitive to changes in interest rates. As a result, in a period of rising interest rates, mortgage-related securities held by the Fund may exhibit additional volatility. This is known as extension risk. In addition, mortgage-related securities are subject to prepayment risk--the risk that borrowers may pay off their

36

mortgages sooner than expected, particularly when interest rates decline. This can reduce the Fund's returns because the Fund may have to reinvest that money at lower prevailing interest rates. The Fund's investments in other asset-backed securities are subject to risks similar to those associated with mortgage-related securities, as well as additional risks associated with the nature of the assets and the servicing of those assets.

Smaller Company Risk

Although under current market conditions the Fund does not at present intend to invest a significant portion of its assets in smaller companies, as market conditions change over time, the Fund may invest more of its assets in such companies. The general risks associated with income-producing securities are particularly pronounced for securities issued by companies with smaller market capitalizations. These companies may have limited product lines, markets or financial resources or may depend on a few key employees. As a result, they may be subject to greater levels of credit, market and issuer risk. Securities of smaller companies may trade less frequently and in lesser volume than more widely held securities, and their values may fluctuate more sharply than those of other securities. Companies with medium-sized market capitalizations may have risks similar to those of smaller companies.

Reinvestment Risk

Reinvestment risk is the risk that income from the Fund's portfolio will decline if and when the Fund invests the proceeds from matured, traded or called debt obligations at market interest rates that are below the portfolio's current earnings rate.

Inflation Risk

Inflation risk is the risk that the value of assets or income from the Fund's investments will be worth less in the future as inflation decreases the value of money. As inflation increases, the real, or inflation-adjusted, value of the Preferred Shares and distributions can decline. However, during any periods of rising inflation, dividend payments on Preferred Shares may increase, which would tend to offset this risk.

Liquidity Risk

The Fund may invest up to 15% of its total assets in illiquid securities (i.e., securities that cannot be disposed of within seven days in the ordinary course of business at approximately the value at which the Fund has valued the securities). For these purposes, bank loans that are part of an issue of at least $250 million in par value will not be considered illiquid, although the Fund's investments in such bank loans, together with its investments in illiquid securities, will not exceed 20% of its total assets. Illiquid securities may be subject to wide fluctuations in market value. The Fund may be subject to significant delays in disposing of illiquid securities. Accordingly, the Fund may be forced to sell these securities at less than fair market value or may not be able to sell them when PIMCO believes it is desirable to do so. Illiquid securities also may entail registration expenses and other transaction costs that are higher than those for liquid securities. Restricted securities,
i.e., securities subject to legal or contractual restrictions on resale, may also be illiquid. However, some restricted securities (such as securities issued pursuant to Rule 144A under the Securities Act of 1933 and certain commercial paper) may be treated as liquid for these purposes. In addition, below investment grade debt securities tend to be less liquid than higher-rated securities.

Market Disruption and Geopolitical Risk

The war with Iraq, its aftermath and the continuing occupation of Iraq are likely to have a substantial impact on the U.S. and world economies and securities markets. The nature, scope and duration of the war and occupation cannot be predicted with any certainty. Terrorist attacks on the World Trade Center and the Pentagon on September 11, 2001 closed some of the U.S. securities markets for a four-day period, and similar events

37

cannot be ruled out. The war and occupation, terrorism and related geopolitical risks have led, and may in the future lead, to increased short-term market volatility and may have adverse long-term effects on U.S. and world economies and markets generally. Those events could also have an acute effect on individual issuers or related groups of issuers. These risks could also adversely affect individual issuers and securities markets, interest rates, auctions, secondary trading, ratings, credit risk, inflation and other factors relating to the Preferred Shares.

Anti-Takeover Provisions

The Declaration and Amended Bylaws include provisions that could limit the ability of other entities or persons to acquire control of the Fund, convert the Fund to open-end status or change the composition of the Board of Trustees. See "Anti-Takeover and Other Provisions in the Declaration of Trust."

Certain Affiliations

Certain broker-dealers may be considered to be affiliated persons of the Fund, the Manager and/or PIMCO because of their possible affiliations with Allianz AG, the ultimate parent of the Manager and PIMCO. Absent an exemption from the Securities and Exchange Commission or other regulatory relief, the Fund is generally precluded from effecting certain principal transactions with affiliated brokers, and its ability to purchase securities being underwritten by an affiliated broker or a syndicate including an affiliated broker, or to utilize affiliated brokers for agency transactions, is subject to restrictions. This could limit the Fund's ability to engage in securities transactions and take advantage of market opportunities. In addition, unless and until the underwriting syndicate is broken in connection with the offering of the Preferred Shares, the Fund will be precluded from effecting principal transactions with brokers who are members of the syndicate.

HOW THE FUND MANAGES RISK

Investment Limitations

The Fund has adopted certain investment limitations designed to limit investment risk and maintain portfolio diversification. These limitations (two of which are listed below) are fundamental and may not be changed without the approval of the holders of a majority of the outstanding Common Shares and any preferred shares (including the Preferred Shares) voting together as a single class, and the approval of the holders of a majority of any preferred shares (including the Preferred Shares) voting as a separate class. The Fund may not:

. Concentrate its investments in a particular "industry," as that term is used in the 1940 Act and as interpreted, modified, or otherwise permitted by regulatory authority having jurisdiction, from time to time; and

. With respect to 75% of the Fund's total assets, purchase the securities of any issuer, except securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities or securities of other investment companies, if as a result, (i) more than 5% of the Fund's total assets would be invested in the securities of that issuer, or (ii) the Fund would hold more than 10% of the outstanding voting securities of that issuer. For the purpose of this restriction, each state and each separate political subdivision, agency, authority or instrumentality of such state, each multi-state agency or authority, and each obligor, if any, is treated as a separate issuer of municipal bonds.

The Fund would be deemed to "concentrate" its investments in a particular industry if it invested more than 25% of its total assets in that industry. The Fund's industry concentration policy does not preclude it from focusing investments in issuers in a group of related industrial sectors (such as different types of utilities).

The Fund is subject to guidelines which are more limiting than the investment restrictions set forth above and to other restrictions set forth in the Statement of Additional Information in order to obtain and maintain

38

ratings on the Preferred Shares of "Aaa" from Moody's and "AAA" from Fitch Ratings, and may become subject to additional guidelines in the future. See "Rating Agency Guidelines." The Fund does not anticipate that such guidelines will have a material adverse effect on the Fund's ability to achieve its investment objectives. See "Rating Agency Guidelines," "Investment Objectives and Policies" and "Investment Restrictions" in the Statement of Additional Information for information about these guidelines and a complete list of the fundamental investment policies of the Fund.

Management of Investment Portfolio and Capital Structure to Limit Leverage Risk

The Fund may take certain actions if short-term interest rates increase or market conditions otherwise change (or the Fund anticipates such an increase or change) and the Fund's leverage begins (or is expected) to adversely affect Common Shareholders. In order to attempt to offset such a negative impact of leverage on Common Shareholders, the Fund may shorten the average maturity or duration of its investment portfolio (by investing in short-term, high quality securities or implementing certain hedging strategies) or may extend the maturity of outstanding preferred shares (including the Preferred Shares). The Fund also may attempt to reduce leverage by redeeming or otherwise purchasing Preferred Shares (subject to any restrictions discussed under "Description of Preferred Shares--Redemption") or by reducing any holdings in other instruments that create leverage. The success of any such attempt to limit leverage risk depends on PIMCO's ability to accurately predict interest rate or other market changes. Because of the difficulty of making such predictions, the Fund may not be successful in managing its interest rate exposure in the manner described above.

If market conditions suggest that additional leverage would be beneficial, the Fund may issue additional preferred shares or sell Preferred Shares that the Fund issues but later repurchases, or utilize other forms of leverage, such as credit default swaps and other derivative instruments. In addition, the Fund's use of credit default swaps and certain other derivative instruments may be limited by the Fund's limitations on illiquid investments to the extent they are determined to be illiquid. See "The Fund's Investment Objectives and Strategies--Portfolio Contents and Other Information" and "Risks--Liquidity Risk."

Hedging and Related Strategies

Subject to the restrictions described under "Rating Agency Guidelines" below, the Fund may use various investment strategies designed to limit the risk of price fluctuations of its portfolio securities and to preserve capital. For instance, the Fund may purchase credit default swap contracts for the purpose of hedging the Fund's exposure to certain issuers and, thereby, decreasing its exposure to credit risk, and it may invest in structured notes or interest rate swap or cap transactions for the purpose of reducing the interest rate sensitivity of the Fund's portfolio and, thereby, decreasing the Fund's exposure to interest rate risk. See "The Fund's Investment Objectives and Strategies--Credit Default Swaps," "The Fund's Investment Objectives and Strategies--Structured Notes and Related Instruments" and "The Fund's Investment Objectives and Strategies--Certain Interest Rate Transactions" in this prospectus. Other hedging strategies that the Fund may use include:
financial futures contracts; short sales; other types of swap agreements or options thereon; options on financial futures; and options based on either an index or individual debt securities whose prices PIMCO believes correlate with the prices of the Fund's investments. Income earned by the Fund from many hedging activities will be treated as capital gain and, if not offset by net realized capital loss, will be distributed to shareholders in taxable distributions. If effectively used, hedging strategies will offset in varying percentages losses incurred on the Fund's investments due to adverse interest rate changes. There is no assurance that these hedging strategies will be available at any time or that PIMCO will determine to use them for the Fund or, if used, that the strategies will be successful. In addition, in accordance with the Rating Agency guidelines described below, the Fund's use of hedging transactions is limited to the types of transactions listed under the definitions of "Fitch Hedging Transactions" and "Moody's Hedging Transactions" in the Glossary.

39

RATING AGENCY GUIDELINES

The Fund is required under Rating Agency guidelines to maintain Moody's Eligible Assets and Fitch Eligible Assets each having in the aggregate a Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount. Moody's and Fitch Ratings have each established separate guidelines for determining Discounted Value. To the extent any particular portfolio holding of the Fund does not satisfy a Rating Agency's guidelines, all or a portion of such holding's value will not be included in the calculation of Discounted Value for purposes of that Rating Agency. The amount of such assets included in the Fund's portfolio at any time may vary depending upon the rating, diversification and other characteristics of the eligible assets included in the portfolio. The Rating Agency guidelines also impose limitations on the Fund's investments.

The Fund is also required under the 1940 Act and Rating Agency guidelines to maintain, with respect to Preferred Shares, asset coverage of at least 200% with respect to senior securities that are stock (as that term is used in the 1940 Act), 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 stock (as used in the 1940 Act) of a closed-end investment company as a condition of declaring dividends on its common shares) ("1940 Act Preferred Shares Asset Coverage").

In the event the Fund does not timely cure a failure to maintain (a) a Discounted Value of its portfolio equal to the Preferred Shares Basic Maintenance Amount or (b) 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 by the Amended Bylaws to redeem Preferred Shares as described under "Description of Preferred Shares--Redemption--Mandatory Redemption."

The Rating Agency guidelines restrict the Fund's use of some types of investment strategies. For example, the guidelines limit the Fund's use of futures, options and other derivative transactions for hedging or investment purposes, prevent the Fund from entering into hedging transactions other than Fitch Hedging Transactions and Moody's Hedging Transactions, restrict the use of forward commitments and similar transactions, and limit the percentage of the Fund's assets that may be invested in any one issuer or type or class of issuer.

The Rating Agency guidelines also prohibit the Fund from taking some types of actions unless it has received written confirmation from the Rating Agencies that such actions would not impair the ratings then assigned to the Preferred Shares. These include restrictions on borrowing money, engaging in short sales, lending portfolio securities, issuing any class or series of shares ranking prior to or on a parity with the Preferred Shares with respect to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up of the Fund or merging or consolidating into or with any other entity.

The restrictions in the Rating Agency guidelines may limit the Fund's ability to make investments that PIMCO believes would benefit the Fund. The descriptions of the Rating Agency guidelines in this section and in "Description of Preferred Shares--Asset Maintenance" are summaries only and are not complete. The Rating Agency guidelines are set forth in their entirety in the Amended Bylaws, the form of which has been filed as an exhibit to the Registration Statement of which this prospectus is a part.

The Fund may, but is not required to, adopt any modifications to the guidelines that may hereafter be established by any Rating Agency. Failure to adopt any such modifications, however, may result in a change in the ratings described above or a withdrawal of ratings altogether. In addition, any Rating Agency may, at any time, change or withdraw any such rating. The Board may, without shareholder approval, amend, alter or repeal certain of the definitions and related provisions which have been adopted by the Fund pursuant to the Rating Agency guidelines only in the event the Fund receives written confirmation from the Rating Agency or Agencies that any such amendment, alteration or repeal would not impair the ratings then assigned to the Preferred Shares.

40

As described by Moody's and Fitch Ratings, a preferred stock rating is an assessment of the capacity and willingness of an issuer to pay preferred stock obligations. The ratings on the Preferred Shares are not recommendations 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 Rating Agency guidelines 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 Moody's and Fitch Ratings by the Fund and/or the Manager and its affiliates and information obtained from other sources. The ratings may be changed, suspended or withdrawn as a result of changes in, or the unavailability of, such information. The Common Shares have not been rated by any rating agency.

A Rating Agency's guidelines will apply to the Preferred Shares only so long as such Rating Agency is rating such shares. The Fund will pay certain fees to Moody's and Fitch Ratings for rating the Preferred Shares. The Fund may at some future time seek to have the Preferred Shares rated by an additional or Substitute Rating Agency.

DESCRIPTION OF PREFERRED SHARES

The following is a brief description of the terms of the Preferred Shares. This description does not purport to be complete and is subject to and qualified in its entirety by reference to the Declaration and Amended Bylaws, including the provisions thereof establishing the Preferred Shares. The Declaration and the form of Amended Bylaws establishing the terms of the Preferred Shares have been filed as exhibits to the Registration Statement of which this prospectus is a part.

Each series of Preferred Shares will be preferred shares of beneficial interest of the Fund that entitle their holders to receive dividends when, as and if declared by the Board of Trustees, out of funds legally available therefor, at a rate per annum that may vary for the successive Dividend Periods for each such series. After the Initial Dividend Period, each Subsequent Dividend Period for each series of Preferred Shares generally will be a 7-Day Dividend Period; provided, however, that prior to any Auction, the Fund may elect to request, subject to certain limitations described herein, upon giving notice to holders thereof, a Special Dividend Period. The Applicable Rate for a particular Dividend Period for a series of Preferred Shares will be determined by an Auction conducted on the Business Day before the start of such Dividend Period. Beneficial Owners and Potential Beneficial Owners of Preferred Shares may participate in Auctions therefor, although, except in the case of Special Dividend Periods of longer than 28 days, Beneficial Owners desiring to continue to hold all of their Preferred Shares regardless of the Applicable Rate resulting from Auctions need not participate. For an explanation of Auctions and the method of determining the Applicable Rate, see "--The Auction."

The nominee of the Securities Depository is expected to be the sole holder of record of each series of Preferred Shares. Accordingly, each purchaser of Preferred Shares must rely on (i) the procedures of the Securities Depository and, if such purchaser is not a member of the Securities Depository, such purchaser's Agent Member, to receive dividends, distributions and notices and to exercise voting rights (if and when applicable) and (ii) the records of the Securities Depository and, if such purchaser is not a member of the Securities Depository, such purchaser's Agent Member, to evidence its beneficial ownership of the Preferred Shares.

When issued and sold, the Preferred Shares of each series will have a liquidation preference of $25,000 per share plus an amount equal to accumulated but unpaid dividends (whether or not earned or declared) and will be fully paid and, except as discussed under "Anti-Takeover and Other Provisions in the Declaration of Trust" below, non-assessable. See "--Liquidation Rights." The Preferred Shares will not be convertible into Common Shares or other shares of beneficial interest of the Fund, and the holders thereof will have no preemptive rights. The Preferred Shares will not be subject to any sinking fund but will be subject to redemption at the option of the Fund at the Optional Redemption Price on any Dividend Payment Date for such series (except during the Initial

41

Dividend Period and during a Non-Call Period) and, in certain circumstances, will be subject to mandatory redemption by the Fund at the Mandatory Redemption Price stated herein. See "--Redemption."

In addition to serving as the Auction Agent in connection with the Auction Procedures described below, Deutsche Bank Trust Company Americas will be the transfer agent, registrar, dividend paying agent and redemption agent for each series of Preferred Shares. The Auction Agent, however, will serve merely as the agent of the Fund, acting in accordance with the Fund's instructions, and will not be responsible for any evaluation or verification of any matters certified to it.

Except in an Auction, the Fund will have the right (to the extent permitted by applicable law) to purchase or otherwise acquire any Preferred Shares so long as the Fund is current in the payment of dividends on Preferred Shares and on any other shares of beneficial interest of the Fund ranking on a parity with the Preferred Shares with respect to the payment of dividends or upon liquidation.

The Auction

General

Holders of the Preferred Shares of each series will be entitled to receive cumulative cash dividends on their shares when, as and if declared by the Board of Trustees, out of the funds legally available therefor, on the Initial Dividend Payment Date with respect to the Initial Dividend Period for each series and, thereafter, on each Dividend Payment Date with respect to a Subsequent Dividend Period for each series (generally a period of seven days, subject to certain exceptions set forth under "--Dividends--General") at the rate per annum equal to the Applicable Rate for each such Dividend Period.

The provisions of the Amended Bylaws establishing the terms of the Preferred Shares offered hereby will provide that the Applicable Rate for each Dividend Period after the Initial Dividend Period for each series will be equal to the rate per annum that the Auction Agent advises has resulted on the Business Day preceding the first day of such Dividend Period due to implementation of the Auction Procedures set forth in the Amended Bylaws in which persons determine to hold or offer to purchase or sell the Preferred Shares. The Auction Procedures are attached as Appendix A to the Statement of Additional Information. Each periodic operation of such procedures with respect to the Preferred Shares is referred to herein as an "Auction." If, however, the Fund should fail to pay or duly provide for the full amount of any dividend on the Preferred Shares or the redemption price of any Preferred Shares called for redemption, the Applicable Rate for the Preferred Shares will be determined as set forth under "--Dividends--Non-Payment Period; Late Charge."

Auction Agency Agreement

The Fund will enter into the Auction Agency Agreement with the Auction Agent, which provides, among other things, that the Auction Agent will follow the Auction Procedures for the purpose of determining the Applicable Rate for each series of Preferred Shares. The Fund will pay the Auction Agent compensation for its services under the Auction Agency Agreement.

The Auction Agent will act as agent for the Fund in connection with Auctions. In the absence of bad faith or negligence on its part, the Auction Agent will not be liable for any action taken, suffered or omitted, or for any error of judgment made, by it in the performance of its duties under the Auction Agency Agreement, and will not be liable for any error of judgment made in good faith unless the Auction Agent shall have been negligent in ascertaining the pertinent facts. Pursuant to the Auction Agency Agreement, the Fund is required to indemnify the Auction Agent for certain losses and liabilities incurred by the Auction Agent without negligence or bad faith on its part in connection with the performance of its duties under such agreement.

42

The Auction Agent may terminate the Auction Agency Agreement upon notice to the Fund, which termination may be no earlier than 60 days following delivery of such notice. If the Auction Agent resigns, the Fund will use its best efforts to enter into an agreement with a successor Auction Agent containing substantially the same terms and conditions as the Auction Agency Agreement. The Fund may terminate the Auction Agency Agreement, provided that prior to such termination the Fund shall have entered into such an agreement with respect thereto with a successor Auction Agent.

Broker-Dealer Agreements

The Auctions require the participation of one or more broker-dealers. The Auction Agent will enter into agreements (collectively, the "Broker-Dealer Agreements") with one or more broker-dealers, or other entities permitted by law to perform the functions required of a Broker-Dealer in the Auction Procedures (collectively, the "Broker-Dealers"), selected by the Fund, which provide for the participation of such Broker-Dealers in Auctions and pursuant to which such Broker-Dealers agree to follow the Auction Procedures. A Broker-Dealer Agreement may be terminated by the Auction Agent or a Broker-Dealer on five days' notice to the other party, provided that the Broker-Dealer Agreement with Citigroup Global Markets Inc. may be terminated only on 60 days' notice to the other party and the Fund.

Securities Depository

The Depository Trust Company initially will act as the Securities Depository for the Agent Members with respect to the Preferred Shares. All of the shares of each series of Preferred Shares initially will be registered in the name of Cede & Co., as nominee of the Securities Depository. Such shares will be subject to the provisions restricting transfers of the Preferred Shares contained in the Amended Bylaws. Cede & Co. initially will be the holder of record of all Preferred Shares, and Beneficial Owners will not be entitled to receive certificates representing their ownership interest in such shares. See Appendix A (Auction Procedures) to the Statement of Additional Information. The Securities Depository will maintain lists of its participants and will maintain the positions (ownership interests) of the Preferred Shares held by each Agent Member, whether as the Beneficial Owner thereof for its own account or as nominee for the Beneficial Owner thereof. Payments made by the Fund to holders of Preferred Shares will be duly made by making payments to the nominee of the Securities Depository.

Auction Procedures

The following is a brief summary of the procedures to be used in conducting Auctions. This summary is qualified in its entirety by reference to the Auction Procedures set forth in Appendix A to the Statement of Additional Information. The Settlement Procedures to be used with respect to Auctions are set forth in Appendix B to the Statement of Additional Information.

Auction Date

An Auction to determine the Applicable Rate for the Preferred Shares offered hereby for each Dividend Period for such shares (other than the Initial Dividend Period therefor) generally will be held on the last Business Day preceding the first day of such Dividend Period, which first day is also the Dividend Payment Date for the preceding Dividend Period (the date of each Auction being referred to herein as an "Auction Date"). The initial Auction Date will be July 7, 2003, for Series M Preferred Shares, July 8, 2003, for Series T Preferred Shares, July 9, 2003, for Series W Preferred Shares, July 10, 2003, for Series TH Preferred Shares and July 11, 2003, for Series F Preferred Shares. Auctions for the Preferred Shares for Dividend Periods after the Initial Dividend Period normally will be held every Monday for Series M Preferred Shares, every Tuesday for Series T Preferred Shares, every Wednesday for Series W Preferred Shares, every Thursday for Series TH Preferred Shares and every Friday for Series F Preferred Shares; and each subsequent Dividend Period normally will begin on the following Tuesday for Series M Preferred Shares, on the following Wednesday for Series T Preferred Shares, on

43

the following Thursday for Series W Preferred Shares, on the following Friday for Series TH Preferred Shares and on the following Monday for Series F Preferred Shares (each also being a Dividend Payment Date). The Auction Date and the first day of the related Dividend Period for a series of Preferred Shares (both of which must be Business Days) need not be consecutive calendar days. See "--Dividends" for information concerning the circumstances under which a Dividend Payment Date may fall on a date other than the days specified above, which may affect the Auction Date.

Orders by Beneficial Owners, Potential Beneficial Owners, Existing Holders and Potential Holders

On or prior to the Submission Deadline on each Auction Date for a series of Preferred Shares:

(a) each Beneficial Owner may submit to its Broker-Dealer by telephone a:

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

(ii) "Bid"--indicating the number of outstanding Preferred Shares, if any, that Beneficial Owner desires to continue to hold, provided that the Applicable Rate for the next succeeding Dividend Period for such shares is not less than the rate per annum then specified by such Beneficial Owner; and/or

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

(b) Broker-Dealers will contact customers who are Potential Beneficial Owners of Preferred Shares to determine whether such Potential Beneficial Owners desire to submit Bids indicating the number of Preferred Shares which they offer to purchase if the Applicable Rate for the next succeeding Dividend Period is not less than the rates per annum specified in such Bids.

The communication by a Beneficial Owner or Potential Beneficial Owner to a Broker-Dealer and the communication by a Broker-Dealer, whether or not acting for its own account, to the Auction Agent of the foregoing information is hereinafter referred to as an "Order" and collectively as "Orders." A Beneficial Owner or a Potential Beneficial Owner placing an Order, including a Broker-Dealer acting in such capacity for its own account, is hereinafter referred to as a "Bidder" and collectively as "Bidders." Any Order submitted by a Beneficial Owner or a Potential Beneficial Owner to its Broker-Dealer, or by a Broker-Dealer to the Auction Agent, prior to the Submission Deadline on any Auction Date shall be irrevocable.

In an Auction, a Beneficial Owner may submit different types of Orders with respect to Preferred Shares then held by such Beneficial Owner, as well as Bids for additional Preferred Shares. If, however, a Beneficial Owner offers through its Broker-Dealer to purchase additional Preferred Shares in such Auction, such Beneficial Owner, for purposes of such offer to purchase additional shares, will be treated as a Potential Beneficial Owner as described below. For information concerning the priority given to different types of Orders placed by Beneficial Owners, see "--Submission of Orders by Broker-Dealers to Auction Agent" below.

The "Maximum Applicable Rate," on any date on which the Applicable Rate is determined for a series of Preferred Shares, will be the Applicable Percentage of the Reference Rate, subject to upward but not downward adjustment in the discretion of the Board of Trustees after consultation with the Broker-Dealers, provided that immediately following any such increase the Fund would be in compliance with the Preferred Shares Basic Maintenance Amount. The Auction Agent will round each applicable Maximum Applicable Rate to the nearest one-thousandth (0.001) of one percent per annum, with any such number ending in five ten-thousandths of one percent being rounded upwards to the nearest one-thousandth (0.001) of one percent. The Auction Agent will not round the applicable Reference Rate as part of its calculation of the Maximum Applicable Rate.

44

The Maximum Applicable Rate for a series of Preferred Shares will depend on the credit rating assigned to such series. The "Applicable Percentage" will be determined based on the lower of the credit ratings assigned on such date to such shares by Moody's and Fitch Ratings, such Applicable Percentage as so determined further subject to adjustment by the Board of Trustees as described in the preceding paragraph, as follows:

    Moody's   Fitch Ratings     Applicable
Credit Rating Credit Rating     Percentage
------------- -------------     ----------
Aa3 or above       AA- or above    150%
  A3 to A1           A- to A+      160%
Baa3 to Baa1       BBB- to BBB+    250%
 Below Baa3         Below BBB-     275%

There is no minimum Applicable Rate in respect of any Dividend Period.

The Fund will take all reasonable action necessary to enable Moody's and Fitch Ratings to provide ratings for each series of Preferred Shares. If such ratings are not made available by Moody's and/or Fitch Ratings, the Underwriters or their affiliates and successors, after consultation with the Fund, will select one or more other rating agencies to act as Substitute Rating Agencies.

Any Bid by a Beneficial Owner specifying a rate per annum higher than the Maximum Applicable Rate will be treated as a Sell Order, and any Bid by a Potential Beneficial Owner specifying a rate per annum higher than the Maximum Applicable Rate will not be considered. See "--Determination of Sufficient Clearing Bids, Winning Bid Rate and Applicable Rate" and "--Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares."

A Broker-Dealer also may hold Preferred Shares in its own account as a Beneficial Owner. A Broker-Dealer thus may submit Orders to the Auction Agent as a Beneficial Owner or a Potential Beneficial Owner and therefore participate in an Auction as an Existing Holder or Potential Holder on behalf of both itself and its customers. Any Order placed with the Auction Agent by a Broker-Dealer as or on behalf of a Beneficial Owner or a Potential Beneficial Owner will be treated in the same manner as an Order placed with a Broker-Dealer by a Beneficial Owner or a Potential Beneficial Owner. Similarly, any failure by a Broker-Dealer to submit to the Auction Agent an Order in respect of any Preferred Shares held by it or its customers who are Beneficial Owners will be treated in the same manner as a Beneficial Owner's failure to submit to its Broker-Dealer an Order in respect of Preferred Shares held by it, as described in the next paragraph. If a Broker-Dealer participates in an Auction as an Existing Holder or a Potential Holder only to represent the interests of a Beneficial Owner or Potential Beneficial Owner, whether it be its customers or itself, all discussion herein relating to the consequences of an Auction for Existing Holders and Potential Holders also applies to the underlying beneficial ownership interests represented thereby. For information concerning the priority given to different types of Orders placed by Existing Holders, see "--Submission of Orders by Broker-Dealers to Auction Agent." Each purchase or sale in an Auction will be settled on the Business Day next succeeding the Auction Date at a price per share equal to $25,000. See "--Notification of Results; Settlement."

If one or more Orders covering in the aggregate all of the outstanding Preferred Shares held by a Beneficial Owner are not submitted to the Auction Agent prior to the Submission Deadline, either because a Broker-Dealer failed to contact such Beneficial Owner or otherwise, the Auction Agent will deem a Hold Order (in the case of an Auction relating to a 7-Day Dividend Period or a Special Dividend Period of 28 days or less) or a Sell Order (in the case of an Auction relating to a Special Dividend Period of longer than 28 days) to have been submitted on behalf of such Beneficial Owner covering the number of outstanding Preferred Shares held by such Beneficial Owner and not subject to Orders submitted to the Auction Agent.

If all of the outstanding Preferred Shares are subject to Submitted Hold Orders, the Dividend Period next succeeding the Auction automatically will be the same length as the immediately preceding Dividend Period, and

45

the Applicable Rate for the next Dividend Period for all of the Preferred Shares will be 80% of the Reference Rate on the date of the applicable Auction.

For the purposes of an Auction, the Preferred Shares for which the Fund shall have given notice of redemption and deposited moneys therefor with the Auction Agent in trust or segregated in an account at the Fund's custodian bank for the benefit of the Auction Agent, as set forth under "--Redemption," will not be considered outstanding and will not be included in such Auction. The Fund may not submit an Order in any Auction.

Neither the Fund nor the Auction Agent will be responsible for a Broker-Dealer's failure to act in accordance with the instructions of Beneficial Owners or Potential Beneficial Owners or failure to comply with the foregoing.

Submission of Orders by Broker-Dealers to Auction Agent

Prior to 1:00 p.m., New York City time, on each Auction Date, or such other time on the Auction Date as may be specified by the Auction Agent (the "Submission Deadline"), each Broker-Dealer will submit to the Auction Agent in writing or through the Auction Agent's auction processing system all Orders obtained by it for the Auction for a series of Preferred Shares to be conducted on such Auction Date, designating itself (unless otherwise permitted by the Fund) the Existing Holder or Potential Holder in respect of the Preferred Shares subject to such Orders. Any Order submitted by a Beneficial Owner or a Potential Beneficial Owner to its Broker-Dealer, or by a Broker-Dealer to the Auction Agent, prior to the Submission Deadline for any Auction Date, shall be irrevocable.

If the rate per annum specified in any Bid contains more than three figures to the right of the decimal point, the Auction Agent will round such rate per annum up to the next highest one-thousandth (0.001) of one percent. If one or more Orders of an Existing Holder are submitted to the Auction Agent and such Orders cover in the aggregate more than the number of outstanding Preferred Shares held by such Existing Holder, such Orders will be considered valid in the following order of priority:

(i) any Hold Order will be considered valid up to and including the number of outstanding Preferred Shares held by such Existing Holder, provided that if more than one Hold Order is submitted by such Existing Holder and the number of Preferred Shares subject to such Hold Orders exceeds the number of outstanding Preferred Shares held by such Existing Holder, the number of Preferred Shares subject to each of such Hold Orders will be reduced pro rata so that such Hold Orders, in the aggregate, will cover exactly the number of outstanding Preferred Shares held by such Existing Holder;

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

(iii) any Sell Order will be considered valid up to and including the excess of the number of outstanding Preferred Shares held by such Existing Holder over the sum of the number of Preferred Shares subject to Hold Orders referred to in clause (i) above and the number of Preferred Shares subject to valid Bids by such Existing Holder referred to in clause (ii) above; provided that, if more than one Sell Order is

46

submitted by any Existing Holder and the number of Preferred Shares subject to such Sell Orders is greater than such excess, the number of Preferred Shares subject to each of such Sell Orders will be reduced pro rata so that such Sell Orders, in the aggregate, will cover exactly the number of Preferred Shares equal to such excess.

If more than one Bid of any Potential Holder is submitted in any Auction, each Bid submitted in such Auction will be considered a separate Bid with the rate per annum and number of Preferred Shares therein specified.

Determination of Sufficient Clearing Bids, Winning Bid Rate and Applicable Rate

Not earlier than the Submission Deadline for each Auction, the Auction Agent will assemble all Orders submitted or deemed submitted to it by the Broker-Dealers (each such "Hold Order," "Bid" or "Sell Order" as submitted or deemed submitted by a Broker-Dealer hereinafter being referred to as a "Submitted Hold Order," a "Submitted Bid" or a "Submitted Sell Order," as the case may be, or as a "Submitted Order") and will determine the excess of the number of outstanding Preferred Shares over the number of outstanding Preferred Shares subject to Submitted Hold Orders (such excess being referred to as the "Available Preferred Shares") and whether Sufficient Clearing Bids have been made in such Auction. Sufficient Clearing Bids will have been made if the number of outstanding Preferred Shares that are the subject of Submitted Bids of Potential Holders with rates per annum not higher than the Maximum Applicable Rate equals or exceeds the number of outstanding shares that are the subject of Submitted Sell Orders (including the number of shares subject to Bids of Existing Holders specifying rates per annum higher than the Maximum Applicable Rate). If Sufficient Clearing Bids have been made, the Auction Agent will determine the lowest rate per annum specified in the Submitted Bids (the "Winning Bid Rate") which would result in the number of shares subject to Submitted Bids specifying such rate per annum or a lower rate per annum being at least equal to the Available Preferred Shares. If Sufficient Clearing Bids have been made, the Winning Bid Rate will be the Applicable Rate for the next Dividend Period for the Preferred Shares then outstanding. If Sufficient Clearing Bids have not been made (other than because all outstanding Preferred Shares are the subject of Submitted Hold Orders), the Dividend Period next following the Auction automatically will be a 7-Day Dividend Period, and the Applicable Rate for such Dividend Period will be equal to the Maximum Applicable Rate.

If Sufficient Clearing Bids have not been made, Beneficial Owners that have Submitted Sell Orders will not be able to sell in the Auction all, and may not be able to sell any, of their Preferred Shares subject to such Submitted Sell Orders. See "--Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares." Thus, under some circumstances, Beneficial Owners may not have liquidity of investment.

Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares

Based on the determinations described under "--Determination of Sufficient Clearing Bids, Winning Bid Rate and Applicable Rate" and subject to the discretion of the Auction Agent to round as described below, Submitted Bids and Submitted Sell Orders will be accepted or rejected in the order of priority set forth in the Auction Procedures with the result that Existing Holders and Potential Holders of a series of Preferred Shares will sell, continue to hold and/or purchase Preferred Shares as set forth below. Existing Holders that submit or are deemed to have submitted Hold Orders will continue to hold the Preferred Shares subject to such Hold Orders.

If Sufficient Clearing Bids have been made:

(a) each Existing Holder that placed a Submitted Bid specifying a rate per annum higher than the Winning Bid Rate or a Submitted Sell Order will sell the outstanding Preferred Shares subject to such Submitted Bid or Submitted Sell Order;

47

(b) each Existing Holder that placed a Submitted Bid specifying a rate per annum lower than the Winning Bid Rate will continue to hold the outstanding Preferred Shares subject to such Submitted Bid;

(c) each Potential Holder that placed a Submitted Bid specifying a rate per annum lower than the Winning Bid Rate will purchase the number of Preferred Shares subject to such Submitted Bid;

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

(e) each Potential Holder that placed a Submitted Bid specifying a rate per annum equal to the Winning Bid Rate will purchase any Available Preferred Shares not accounted for in clause (b), (c) or (d) above on a pro rata basis based on the Preferred Shares subject to all such Submitted Bids of Potential Holders.

If Sufficient Clearing Bids have not been made (other than because all outstanding Preferred Shares are the subject of Submitted Hold Orders):

(a) each Existing Holder that placed a Submitted Bid specifying a rate per annum equal to or lower than the Maximum Applicable Rate will continue to hold the outstanding Preferred Shares subject to such Submitted Bid;

(b) each Potential Holder that placed a Submitted Bid specifying a rate per annum equal to or lower than the Maximum Applicable Rate will purchase the number of Preferred Shares subject to such Submitted Bid; and

(c) each Existing Holder that placed a Submitted Bid specifying a rate per annum higher than the Maximum Applicable Rate or a Submitted Sell Order will sell a number of outstanding Preferred Shares determined on a pro rata basis based on the outstanding Preferred Shares subject to all such Submitted Bids and Submitted Sell Orders.

If as a result of the Auction Procedures described above any Existing Holder would be entitled or required to sell, or any Potential Holder would be entitled or required to purchase, a fraction of a Preferred Share, the Auction Agent, in such manner as, in its sole discretion, it shall determine, will round up or down the number of Preferred Shares being sold or purchased on such Auction Date so that each share sold or purchased by each Existing Holder or Potential Holder will be a whole Preferred Share. If any Potential Holder would be entitled or required to purchase less than a whole Preferred Share, the Auction Agent, in such manner as, in its sole discretion, it shall determine, will allocate Preferred Shares for purchase among Potential Holders so that only whole Preferred Shares are purchased by any such Potential Holder, even if such allocation results in one or more of such Potential Holders not purchasing any Preferred Shares.

Notification of Results; Settlement

The Auction Agent will advise each Broker-Dealer who submitted a Bid or Sell Order in an Auction whether such Bid or Sell Order was accepted or rejected in whole or in part and of the Applicable Rate for the next Dividend Period for the related Preferred Shares by telephone or through the Auction Agent's auction processing system at approximately 3:00 p.m., New York City time, on the Auction Date for such Auction. Each such Broker-Dealer that submitted an Order for the account of a customer then will advise such customer whether such Bid or Sell Order was accepted or rejected, will confirm purchases and sales with each customer purchasing or selling Preferred Shares as a result of the Auction and will advise each customer purchasing or

48

selling Preferred Shares to give instructions to its Agent Member of the Securities Depository to pay the purchase price against delivery of such shares or to deliver such shares against payment therefor as appropriate. If a customer selling Preferred Shares as a result of an Auction fails to instruct its Agent Member to deliver such shares, the Broker-Dealer that submitted such customer's Bid or Sell Order will instruct such Agent Member to deliver such shares against payment therefor. Each Broker-Dealer that submitted a Hold Order in an Auction on behalf of a customer also will advise such customer of the Applicable Rate for the next Dividend Period for the Preferred Shares. The Auction Agent will record each transfer of Preferred Shares on the record book of Existing Holders to be maintained by the Auction Agent.

In accordance with the Securities Depository's normal procedures, on the day after each Auction Date, the transactions described above will be executed through the Securities Depository, and the accounts of the respective Agent Members at the Securities Depository will be debited and credited as necessary to effect the purchases and sales of Preferred Shares as determined in such Auction. Purchasers will make payment through their Agent Members in same-day funds to the Securities Depository against delivery through their Agent Members; the Securities Depository will make payment in accordance with its normal procedures, which now provide for payment in same-day funds. If the procedures of the Securities Depository applicable to Preferred Shares shall be changed to provide for payment in next-day funds, then purchasers may be required to make payment in next-day funds. If the certificates for the Preferred Shares are not held by the Securities Depository or its nominee, payment will be made in same-day funds to the Auction Agent against delivery of such certificates.

If any Existing Holder selling Preferred Shares in an Auction fails to deliver such shares, the Broker-Dealer of any person that was to have purchased Preferred Shares in such Auction may deliver to such person a number of whole Preferred Shares that is less than the number of shares that otherwise was to be purchased by such person. In such event, the number of Preferred Shares to be so delivered will be determined by such Broker-Dealer. Delivery of such lesser number of shares will constitute good delivery. Each Broker-Dealer Agreement also will provide that neither the Fund nor the Auction Agent will have responsibility or liability with respect to the failure of a Beneficial Owner or Potential Beneficial Owner or their respective Agent Members to deliver Preferred Shares or to pay for Preferred Shares purchased or sold pursuant to an Auction or otherwise.

Broker-Dealers

General

The Auction Agent after each Auction will pay a service charge from funds provided by the Fund to each Broker-Dealer on the basis of the purchase price of Preferred Shares placed by such Broker-Dealer at such Auction. The service charge (i) for any 7-Day Dividend Period shall be payable at the annual rate of 0.25% of the purchase price of the Preferred Shares placed by such Broker-Dealer in any such Auction and (ii) for any Special Dividend Period shall be determined by mutual consent of the Fund and any such Broker-Dealer or Broker-Dealers and shall be based upon a selling concession that would be applicable to an underwriting of fixed or variable rate preferred shares with a similar final maturity or variable rate dividend period, respectively, at the commencement of the Dividend Period with respect to such Auction. For the purposes of the preceding sentence, the Preferred Shares will be placed by a Broker-Dealer if such shares were (i) the subject of Hold Orders deemed to have been made by Beneficial Owners that were acquired by such Beneficial Owners through such Broker-Dealer or (ii) the subject of any of the following Orders submitted by such Broker-Dealer: (A) a Submitted Bid of a Beneficial Owner that resulted in such Beneficial Owner's continuing to hold such shares as a result of the Auction, (B) a Submitted Bid of a Potential Beneficial Owner that resulted in such Potential Beneficial Owner's purchasing such shares as a result of the Auction or (C) a Submitted Hold Order.

The Broker-Dealer Agreements provide that a Broker-Dealer may submit Orders in Auctions for its own account, unless the Fund notifies all Broker-Dealers that they no longer may do so; provided that Broker-Dealers may continue to submit Hold Orders and Sell Orders. If a Broker-Dealer submits an Order for its own account in any Auction of Preferred Shares, it may have knowledge of Orders placed through it in that Auction and

49

therefore have an advantage over other Bidders, but such Broker-Dealer would not have knowledge of Orders submitted by other Broker-Dealers in that Auction.

Secondary Market Trading and Transfers of Preferred Shares

The Broker-Dealers may maintain a secondary trading market in the Preferred Shares outside of Auctions; however, they have no obligation to do so, and may discontinue such activity at any time. There can be no assurance that a secondary market for the Preferred Shares will develop or, if it does develop, that it will provide holders with a liquid trading market (i.e., trading will depend on the presence of willing buyers and sellers, and the trading price is subject to variables to be determined at the time of the trade by the Broker-Dealers). The Preferred Shares will not be registered on any stock exchange or on any automated quotation system. An increase in the level of interest rates, particularly during any Long Term Dividend Period for a series of Preferred Shares, likely will have an adverse effect on the secondary market price of such Preferred Shares, and a selling shareholder may sell Preferred Shares between Auctions at a price per share of less than $25,000.

A Beneficial Owner or an Existing Holder may sell, transfer or otherwise dispose of Preferred Shares only in whole shares and only (1) pursuant to a Bid or Sell Order placed with the Auction Agent in accordance with the Auction Procedures, (2) to a Broker-Dealer or (3) to such other persons as may be permitted by the Fund; provided, however, that (a) a sale, transfer or other disposition of 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 the foregoing 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, such Beneficial Owner or Existing Holder, its Broker-Dealer, if applicable, or its Agent Member advises the Auction Agent of such transfer.

Dividends

General

The holders of Preferred Shares of each series will 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 below under "--Determination of Dividend Rate," payable on the dates set forth below. Dividends on the Preferred Shares so declared and payable will be paid in preference to and in priority over any dividends so declared and payable on the Common Shares.

Dividends on each series of Preferred Shares will accumulate from the date on which the Fund originally issues the Preferred Shares (the "Date of Original Issue") and will be payable on the Preferred Shares on the dates described below. Dividends on a series of Preferred Shares with respect to the Initial Dividend Period shall be payable on the Initial Dividend Payment Date for that series. Following the Initial Dividend Payment Date, dividends on each series of Preferred Shares will be payable, at the option of the Fund, either (i) with respect to any 7-Day Dividend Period and any Short Term Dividend Period of 35 or fewer days, on the day next succeeding the last day thereof or (ii) with respect to any Short Term Dividend Period of more than 35 days and with respect to any Long Term Dividend Period, monthly on the first Business Day of each calendar month during such Short Term Dividend Period or Long Term Dividend Period and on the day next succeeding the last day thereof (each such date referred to in clause (i) or (ii) being referred to herein as a "Normal Dividend Payment Date"), except that if such Normal Dividend Payment Date is not a Business Day, the Dividend Payment Date will be the first Business Day next succeeding such Normal Dividend Payment Date. Although any particular Dividend Payment Date may not occur on the originally scheduled date because of the exceptions discussed above, the next succeeding Dividend Payment Date, subject to such exceptions, will nonetheless occur on the next following originally scheduled date. If for any reason a Dividend Period for a series of Preferred Shares is scheduled to begin on the same day and end on the same day as a Dividend Period for another series of Preferred Shares, then

50

the last day of the Dividend Period for such other series of Preferred Shares shall be the second Business Day next succeeding such scheduled day unless the Fund obtains the opinion of tax counsel referred to below. Subject to the limitation in the next sentence, if for any reason a Dividend Payment Date cannot be fixed as described above, then the Board of Trustees will fix the Dividend Payment Date. However, no Dividend Period of any series of Preferred Shares shall be co-extensive with any Dividend Period of any other series of Preferred Shares unless the Fund has received an opinion of tax counsel that having such co-extensive periods will not affect the deductibility, for federal income tax purposes, of dividends paid on the different series of Preferred Shares. The Board of Trustees before authorization of a dividend may change a Dividend Payment Date if such change does not adversely affect the contract rights of the holders of Preferred Shares set forth in the Declaration or Amended Bylaws. The Initial Dividend Period, 7-Day Dividend Periods and Special Dividend Periods with respect to a series of Preferred Shares are hereinafter sometimes referred to as "Dividend Periods." Each dividend payment date determined as provided above is hereinafter referred to as a "Dividend Payment Date."

Prior to each Dividend Payment Date, the Fund is required to deposit with the Auction Agent sufficient funds for the payment of declared dividends. The Fund does not intend to establish any reserves for the payment of dividends.

Each dividend will be paid to the record holder of the Preferred Shares on the Dividend Payment Date, which holder is expected to be the nominee of the Securities Depository. See "--The Auction--Securities Depository." The Securities Depository will credit the accounts of the Agent Members of the Existing Holders in accordance with the Securities Depository's normal procedures, which provide for payment in same-day funds. The Agent Member of an Existing Holder will be responsible for holding or disbursing such payments on the applicable Dividend Payment Date to such Existing Holder in accordance with the instructions of such Existing Holder. Dividends in arrears for any past Dividend Period may be declared and paid at any time, without reference to any regular Dividend Payment Date, to the nominee of the Securities Depository. Any dividend payment made on the Preferred Shares first shall be credited against the earliest declared but unpaid dividends accumulated with respect to such shares.

Holders of the Preferred Shares will not be entitled to any dividends, whether payable in cash, property or stock, in excess of full cumulative dividends except as described under "--Non-Payment Period; Late Charge" below. No interest will be payable in respect of any dividend payment or payments on the Preferred Shares which may be in arrears.

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

The Fund intends to qualify each year for taxation as a regulated investment company eligible for treatment under the provisions of Subchapter M of the Code. If the Fund so qualifies and satisfies certain distribution requirements, the Fund will not be subject to federal income tax on income distributed in a timely manner to its shareholders in the form of dividends or capital gain distributions. See "Tax Matters."

51

Notification of Dividend Period

The Fund, at its sole option and to the extent permitted by law, by telephonic and written notice (a "Request for Special Dividend Period") to the Auction Agent and to each Broker-Dealer, may request that the next succeeding Dividend Period for a series of Preferred Shares will be a number of days (other than seven), evenly divisible by seven, and not fewer than fourteen nor more than 364 in the case of a Short Term Dividend Period or one whole year or more but not greater than five years in the case of a Long Term Dividend Period, specified in such notice, provided that the Fund may not give a Request for Special Dividend Period for a Dividend Period of greater than 28 days (and any such request will be null and void) unless, for any Auction occurring after the initial Auction, Sufficient Clearing Bids were made in the last occurring Auction and unless full cumulative dividends and any amounts due with respect to redemptions payable prior to such date have been paid in full. Such Request for Special Dividend Period, in the case of a Short Term Dividend Period, shall be given on or prior to the second Business Day but not more than seven Business Days prior to an Auction Date for the Preferred Shares of that series and, in the case of a Long Term Dividend Period, shall be given on or prior to the second Business Day but not more than 28 days prior to an Auction Date for the Preferred Shares of that series. Upon receiving such Request for Special Dividend Period, the Broker-Dealers jointly shall determine the Optional Redemption Price of the Preferred Shares of that series during such Special Dividend Period and the Specific Redemption Provisions and shall give the Fund and the Auction Agent written notice (a "Response") of such determination by no later than the second Business Day prior to such Auction Date. In making such determination, the Broker-Dealers will consider (i) existing short-term and long-term market rates and indices of such short-term and long-term rates, (ii) existing market supply and demand for short-term and long-term securities,
(iii) existing yield curves for short-term and long-term securities comparable to the Preferred Shares, (iv) industry and financial conditions which may affect the Preferred Shares of that series, (v) the investment objectives of the Fund and (vi) the Dividend Periods and dividend rates at which current and potential beneficial holders of the Preferred Shares would remain or become beneficial holders.

After providing the Request for Special Dividend Period to the Auction Agent and each Broker-Dealer as set forth above, the Fund, by no later than the second Business Day prior to such Auction Date, may give a notice (a "Notice of Special Dividend Period") to the Auction Agent, the Securities Depository and each Broker-Dealer, which notice will specify (i) the duration of the Special Dividend Period, (ii) the Optional Redemption Price, if any, as specified in the related Response and (iii) the Specific Redemption Provisions, if any, as specified in the related Response. The Fund has agreed to provide a copy of such Notice of Special Dividend Period to Moody's and Fitch Ratings (and will provide such notice to any Substitute Rating Agency then rating the Preferred Shares). The Fund will not give a Notice of Special Dividend Period, and, if such Notice of Special Dividend Period has been given already, will give telephonic and written notice of its revocation (a "Notice of Revocation") to the Auction Agent, each Broker-Dealer, and the Securities Depository on or prior to the Business Day prior to the relevant Auction Date if (x) either the 1940 Act Preferred Shares Asset Coverage is not satisfied or the Fund fails to maintain Moody's Eligible Assets and Fitch Eligible Assets with an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount, on each of the two Valuation Dates immediately preceding the Business Day prior to the relevant Auction Date on an actual basis and on a pro forma basis giving effect to the proposed Special Dividend Period (using as a pro forma dividend rate with respect to such Special Dividend Period the dividend rate which the Broker-Dealers shall advise the Fund is an approximately equal rate for securities similar to the Preferred Shares with an equal dividend period) or (y) sufficient funds for the payment of dividends payable on the immediately succeeding Dividend Payment Date have not been irrevocably deposited with the Auction Agent by the close of business on the third Business Day preceding the Auction Date immediately preceding such Dividend Payment Date. The Fund also shall provide a copy of such Notice of Revocation to Moody's and Fitch Ratings (or any Substitute Rating Agency then rating the Preferred Shares). If the Fund is prohibited from giving a Notice of Special Dividend Period as a result of the factors enumerated in clause (x) or (y) above or if the Fund gives a Notice of Revocation with respect to a Notice of Special Dividend Period, the next succeeding Dividend Period for that series will be a 7-Day Dividend Period. In addition, in the event Sufficient Clearing Bids are not made in an Auction, or if an Auction is not held for any reason, the next succeeding Dividend Period will be a 7-Day Dividend Period, and the Fund may not again give a

52

Notice of Special Dividend Period (and any such attempted notice will be null and void) until Sufficient Clearing Bids have been made in an Auction with respect to a 7-Day Dividend Period. If an Auction is not held because an unforeseen event or unforeseen events cause a day that otherwise would have been a Dividend Payment Date or an Auction Date not to be a Business Day, then the length of the Dividend Period relating to such Dividend Payment Date shall be extended by seven days (or a multiple thereof if necessary because of such unforeseen event or events) (an "Extension Period"), the Applicable Rate for such Extension Period shall be the Applicable Rate for the Dividend Period so extended and the Dividend Payment Date for such Dividend Period shall be the first Business Day next succeeding the end of such Extension Period. Solely for purposes of (1) the foregoing sentence, (2) the proviso in clause (i) of the definition of "Non-Payment Period" under "--Non-Payment Period; Late Charge" below and (3) the second parenthetical in the fifth sentence of the same paragraph in which "Non-Payment Period" is defined, any day on which banks in New York City generally are closed, for any reason, while the New York Stock Exchange remains open for trading and any day which otherwise would be a Business Day as defined in the Amended Bylaws on which the Auction Agent is closed for business, for any reason, shall be considered a day which is not a Business Day.

Determination of Dividend Rate

The dividend rate on a series of Preferred Shares during the period from and including the Date of Original Issue for the Preferred Shares to but excluding the Initial Dividend Payment Date for that series of Preferred Shares (the "Initial Dividend Period") will be the rate per annum set forth on the inside of the front cover page hereof. Commencing on the Initial Dividend Payment Date for a series of Preferred Shares, the Applicable Rate on that series of Preferred Shares for each Subsequent Dividend Period, which Subsequent Dividend Period shall be a period commencing on and including a Dividend Payment Date and ending on and including the calendar day prior to the next Dividend Payment Date (or last Dividend Payment Date in a Dividend Period if there is more than one Dividend Payment Date), shall be equal to the rate per annum that results from the Auction with respect to such Subsequent Dividend Period. Cash dividends shall be calculated as set forth above under "Dividends--General."

Non-Payment Period; Late Charge

A "Non-Payment Period" for a series of Preferred Shares will commence if the Fund fails to (i) declare, prior to the close of business on the second Business Day preceding any Dividend Payment Date, for payment (to the extent permitted as described below) within three Business Days after such Dividend Payment Date to the persons who held such shares as of 12:00 noon, New York City time, on the Business Day preceding such Dividend Payment Date, the full amount of any dividend on the Preferred Shares payable on such Dividend Payment Date, provided, however, that if the Fund is not able to make such declaration in compliance with the foregoing because an unforeseen event or unforeseen events causes or cause a day that otherwise would have been a Business Day not to be a Business Day, then the Fund may make such declaration on the Business Day immediately preceding the Dividend Payment Date, if possible, or, if not possible, on the Dividend Payment Date, and in such case the Fund shall not be deemed to have failed to declare a dividend otherwise required to be declared, or (ii) deposit, irrevocably in trust, in same-day funds, with the Auction Agent by 12:00 noon, New York City time, (A) on such Dividend Payment Date the full amount of any cash dividend on such shares payable (if declared) on such Dividend Payment Date or (B) on any redemption date for any Preferred Shares called for redemption, the Mandatory Redemption Price per share of such Preferred Shares or, in the case of an optional redemption, the Optional Redemption Price per share. Such Non-Payment Period will consist of the period commencing on and including the aforementioned Dividend Payment Date or redemption date, as the case may be, and ending on and including the Business Day on which, by 12:00 noon, New York City time, all unpaid cash dividends and unpaid redemption prices shall have been so deposited or otherwise shall have been made available to the applicable holders in same-day funds, provided that a Non-Payment Period for the Preferred Shares will not end unless the Fund shall have given at least five days' but no more than 30 days' written notice of such deposit or availability to the Auction Agent, the Securities Depository and all holders of the Preferred Shares of such series. Notwithstanding the foregoing, the failure by the Fund to deposit funds as provided for by

53

clause (ii) (A) or (ii) (B) above within three Business Days after any Dividend Payment Date or redemption date, as the case may be, in each case to the extent contemplated below, shall not constitute a "Non-Payment Period." The Applicable Rate for each Dividend Period for the Preferred Shares of any series, commencing during a Non-Payment Period, will be equal to the Non-Payment Period Rate; and each Dividend Period commencing after the first day of and during, but not after the end of, a Non-Payment Period shall be a 7-Day Dividend Period. Any dividend on the Preferred Shares due on any Dividend Payment Date for such shares (if, prior to the close of business on the second Business Day preceding such Dividend Payment Date, the Fund has declared such dividend payable on such Dividend Payment Date to the persons who held such shares as of 12:00 noon, New York City time, on the Business Day preceding such Dividend Payment Date) or redemption price with respect to such shares not paid to such persons when due may be paid to such persons in the same form of funds by 12:00 noon, New York City time, on any of the first three Business Days after such Dividend Payment Date or due date, as the case may be, provided that such amount is accompanied by a late charge calculated for such period of non-payment at the Non-Payment Period Rate applied to the amount of such non-payment based on the actual number of days comprising such period (excluding any days that would have been Business Days but for the occurrence of any unforeseen event or unforeseen events that caused such days not to be Business Days) divided by 365, and in such case such period shall not constitute a Non-Payment Period; provided, however, that the Fund shall not be required to pay any late charge if it declares a dividend on the Dividend Payment Date or the Business Day immediately preceding such Dividend Payment Date in accordance with clause (i) of the definition of "Non-Payment Period" and deposits payment for such dividend as contemplated by clause (ii)(A) of the definition of "Non-Payment Period" on or before the second Business Day succeeding the day on which the dividend was declared. In the case of a willful failure of the Fund to pay a dividend on a Dividend Payment Date or to redeem any Preferred Shares on the date set for such redemption, the preceding sentence shall not apply, and the Applicable Rate for the Dividend Period commencing during the Non-Payment Period resulting from such failure shall be the Non-Payment Period Rate. For the purposes of the foregoing, payment to a person in same-day funds on any Business Day at any time will be considered equivalent to payment to that person in New York Clearing House (next-day) funds at the same time on the preceding Business Day, and any payment made after 12:00 noon, New York City time, on any Business Day shall be considered to have been made instead in the same form of funds and to the same person before 12:00 noon, New York City time, on the next Business Day. The "Non-Payment Period Rate" initially will be 300% of the applicable Reference Rate, provided that the Board of Trustees shall have the authority to adjust, modify, alter or change from time to time the initial Non-Payment Period Rate if the Board of Trustees determines and each of Moody's and Fitch Ratings (or any Substitute Rating Agency) advise the Fund in writing that such adjustment, modification, alteration or change will not adversely affect its then current rating on the Preferred Shares.

Restrictions on Dividends and Other Payments

Under the 1940 Act, the Fund may not declare dividends or make other distributions on Common Shares or purchase any such shares if, at the time of the declaration, distribution or purchase, as applicable (and after giving effect thereto), asset coverage (as defined in the 1940 Act) with respect to all senior securities, including the outstanding Preferred Shares would be less than 200% (or such other percentage as in the future may be required by law). The foregoing limitations on dividends, other distributions and purchases in certain circumstances may impair the Fund's ability to maintain its qualification as a regulated investment company under the Code. See "Tax Matters." Upon any failure to pay dividends on the Preferred Shares for two years or more, the holders of the Preferred Shares will acquire certain additional voting rights. See "--Voting Rights" below.

For so long as any Preferred Shares are outstanding, the Fund will not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or options, warrants or rights to subscribe for or purchase, Common Shares or other shares, if any, ranking junior to the Preferred Shares as to dividends or upon liquidation) in respect of Common Shares or any other shares of the Fund ranking junior to or on a parity with the Preferred Shares as to dividends or upon liquidation, or call for redemption, redeem, purchase or otherwise acquire for consideration any Common Shares or any other such junior shares (except by

54

conversion into or exchange for shares of beneficial interest of the Fund ranking junior to Preferred Shares as to dividends and upon liquidation) or any such parity shares (except by conversion into or exchange for shares of beneficial interest of the Fund ranking junior to or on a parity with Preferred Shares as to dividends and upon liquidation), unless and only if (A) immediately after such transaction, the Fund would have Moody's Eligible Assets and Fitch Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount, and the 1940 Act Preferred Shares Asset Coverage (see "--Asset Maintenance" and "--Redemption" below) would be satisfied, (B) full cumulative dividends on the Preferred Shares due on or prior to the date of the transaction have been declared and paid or shall have been declared and sufficient funds for the payment thereof deposited with the Auction Agent and (C) the Fund has redeemed the full number of Preferred Shares required to be redeemed by any provision for mandatory redemption contained in the Amended Bylaws.

Asset Maintenance

The Fund will be required to satisfy two separate asset maintenance requirements under the terms of the Amended Bylaws. These requirements are summarized below.

1940 Act Preferred Shares Asset Coverage

The Fund will be required under the Amended Bylaws to maintain, with respect to the Preferred Shares, as of the last Business Day of each month in which any Preferred Shares are outstanding, the 1940 Act Preferred Shares Asset Coverage. If the Fund fails to maintain the 1940 Act Preferred Shares Asset Coverage and such failure is not cured as of the last Business Day of the following month (the "1940 Act Cure Date"), the Fund will be required under certain circumstances to redeem certain of the Preferred Shares. See "--Redemption" below.

The 1940 Act Preferred Shares Asset Coverage immediately following the issuance of Preferred Shares offered hereby (after giving effect to the deduction of the sales load and offering expenses for the Preferred Shares), computed using the Fund's net assets as of June 11, 2003, and assuming the Preferred Shares had been issued as of such date, will be as follows:

 Value of the Fund's total assets less all liabilities
  and indebtedness not represented by senior securities     $2,572,534,640
-------------------------------------------             =   -----------    =   286%
   Senior securities representing indebtedness plus         $  900,000,000
        liquidation value of the Preferred Shares

Preferred Shares Basic Maintenance Amount

So long as the Preferred Shares are outstanding and any Rating Agency so requires, the Fund will be required under the Amended Bylaws to maintain as of the last Business Day of each week, or such other date as the Fund and the Rating Agencies may agree to for purposes of determining the Preferred Shares Basic Maintenance Amount (a "Valuation Date"), Moody's Eligible Assets and Fitch Eligible Assets each having in the aggregate a Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount. If the Fund fails to meet such requirement as of any Valuation Date and such failure is not cured on or before the sixth Business Day after such Valuation Date (the "Preferred Shares Basic Maintenance Cure Date"), the Fund will be required in certain circumstances to redeem certain of the Preferred Shares. Upon any failure to maintain the required Discounted Value, the Fund will use its best efforts to alter the composition of its portfolio to retain a Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount on or prior to the Preferred Shares Basic Maintenance Cure Date. See "--Redemption."

The "Preferred Shares Basic Maintenance Amount" as of any Valuation Date is defined as the dollar amount equal to the sum of (i)(A) the product of the number of Preferred Shares outstanding on such date multiplied by $25,000, plus any redemption premium applicable to Preferred Shares then subject to redemption; (B) the

55

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 each series of Preferred Shares outstanding 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 49th day after such Valuation Date, at the Maximum Applicable Rate (calculated as if such Valuation Date were the Auction Date for the Dividend Period commencing on such Dividend Payment Date) for a 7-Day Dividend Period of shares of such series to commence on such Dividend Payment Date, multiplied by the Volatility Factor (except that (1) if such Valuation Date occurs during a Non-Payment Period, the dividend for purposes of calculation would accumulate at the current Non-Payment Period Rate and (2) for those days during the period described in this clause (C) in respect of which the Applicable Rate in effect immediately prior to such Dividend Payment Date will remain in effect, the dividend for purposes of calculation would accumulate at such Applicable Rate in respect of those days); (D) the amount of anticipated expenses of the Fund for the 90 days subsequent to such Valuation Date; and (E) any current liabilities as of such Valuation Date to the extent not reflected in any of
(i)(A) through (i)(D) (including, without limitation, any payables for 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 securities rated MIG-1, VMIG-1 or P-1 by Moody's, 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) through (i)(E) becomes payable, otherwise the Discounted Value) of any of the Fund's assets irrevocably deposited by the Fund for the payment of any of (i)(A) through (i)(E).

For purposes of determining whether the Fund has Fitch Eligible Assets with an aggregate Discounted Value that equals or exceeds the Preferred Shares Basic Maintenance Amount, the Discounted Value of Fitch Eligible Assets that the Fund is obligated to deliver or receive pursuant to an outstanding futures contract or option shall be as follows: (i) assets subject to call options written by the Fund either that are exchange-traded and "readily reversible" or that expire within 49 days after the date as of which such valuation is made shall be valued at the lesser of (A) Discounted Value and (B) the exercise price of the call option written by the Fund; (ii) assets subject to call options written by the Fund not meeting the requirements of clause (i) of this sentence shall have no value; (iii) assets subject to put options written by the Fund shall be valued at the lesser of (A) the exercise price and (B) the Discounted Value of the assets subject to the option; and (iv) where delivery may be made to the Fund with any security of a class of securities, the Fund shall assume that it will take delivery of the security with the lowest Discounted Value.

For purposes of determining whether the Fund has Moody's Eligible Assets with an aggregate Discounted Value that equals or exceeds the Preferred Shares Basic Maintenance Amount, the Discounted Value of Moody's Eligible Assets that the Fund is obligated to deliver or receive pursuant to an outstanding futures contract or option shall be as follows: (i) assets subject to call options written by the Fund either that are exchange-traded and "readily reversible" or that expire within 49 days after the date as of which such valuation is made shall be valued at the lesser of (A) Discounted Value and (B) the exercise price of the call option written by the Fund; (ii) assets subject to call options written by the Fund not meeting the requirements of clause (i) of this sentence shall have no value; (iii) assets subject to put options written by the Fund shall be valued at the lesser of (A) the exercise price and (B) the Discounted Value of the assets subject to the option; (iv) futures contracts shall be valued at the lesser of (A) the settlement price and (B) the Discounted Value of the assets subject to the futures contract, provided that, if a contract matures within 49 days after the date as of which such valuation is made, where the Fund is the seller the contract may be valued at the settlement price and where the Fund is the buyer the contract may be valued at the Discounted Value of the assets subject to the futures contract; and (v) where delivery may be made to the Fund with any security of a class of securities, the Fund shall assume that it will take delivery of the security with the lowest Discounted Value.

In addition, for purposes of determining whether the Fund has Moody's Eligible Assets and Fitch Eligible Assets each with an aggregate Discounted Value that equals or exceeds the Preferred Shares Basic Maintenance Amount, the following amounts shall be subtracted from the aggregate Discounted Value of the Moody's

56

Eligible Assets and Fitch Eligible Assets held by the Fund to the extent the relevant asset is a Moody's Eligible Asset or Fitch Eligible Asset, as applicable: (i) 10% of the exercise price of a written call option; (ii) the exercise price of any written put option; (iii) where the Fund is the seller under a financial futures contract, 10% of the settlement price of the financial futures contract; (iv) where the Fund is the purchaser under a financial futures contract, any amounts payable by the Fund under such financial futures contract; (v) the settlement price of the underlying financial futures contract if the Fund writes put options on a financial futures contract; and (vi) 105% of the Market Value of the underlying financial futures contracts if the Fund writes call options on a financial futures contract and does not own the underlying contract. The Discounted Value of all forward commitments to which the Fund is a party and of all securities deliverable to the Fund pursuant to such forward commitments shall be zero.

The Discount Factors and guidelines for determining the market value of the Fund's portfolio holdings have been based on criteria established in connection with rating the Preferred Shares. These factors include, but are not limited to, the sensitivity of the market value of the relevant asset to changes in interest rates, the liquidity and depth of the market for the relevant asset, the credit quality of the relevant asset (for example, the lower the rating of a debt obligation, the higher the related Discount Factor) and the frequency with which the relevant asset is marked to market. In no event shall the Discounted Value of any asset of the Fund exceed its unpaid principal balance or face amount as of the date of calculation. The Discount Factor relating to any asset of the Fund and the Preferred Shares Basic Maintenance Amount, the assets eligible for inclusion in the calculation of the Discounted Value of the Fund's portfolio and certain definitions and methods of calculation relating thereto may be changed from time to time by the Fund, without shareholder approval, but only in the event the Fund receives written confirmation from Moody's and Fitch Ratings, or any Substitute Rating Agency, that any such changes would not impair the ratings then assigned to the Preferred Shares by Moody's and Fitch Ratings or any such Substitute Rating Agency.

On or before the third Business Day after a Valuation Date on which the Fund fails to maintain Moody's Eligible Assets or Fitch Eligible Assets with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount, the Fund is required to deliver to the Auction Agent and, as applicable, Moody's or Fitch Ratings a report with respect to the calculation of the Preferred Shares Basic Maintenance Amount and the value of its portfolio holdings (a "Preferred Shares Basic Maintenance Report") as of the date of such failure. Additionally, on or before the third Business Day after the first day of a Special Dividend Period, the Fund will deliver a Preferred Shares Basic Maintenance Report to the Auction Agent and each Rating Agency. The Fund also will deliver a Preferred Shares Basic Maintenance Report as of the last Business Day of the last month of each fiscal quarter of the Fund on or before the third Business Day after such day, although the Fund may agree at a later date to provide such a report to one or more of the Rating Agencies as of the last Business Day of each month, rather than on a quarterly basis. Within ten Business Days after delivery of the report relating to the last Business Day of the last fiscal quarter of each fiscal year of the Fund, the Fund will deliver a letter prepared by the Fund's independent accountants regarding the accuracy of the calculations made by the Fund in its most recent Preferred Shares Basic Maintenance Report (and in another Preferred Shares Basic Maintenance Report, randomly selected by the Fund's independent accountants, that was delivered during such fiscal quarter). Also, on or before 5:00 p.m., New York City time, on the first Business Day after any Common Shares are repurchased by the Fund, the Fund will complete and deliver to the Auction Agent and each Rating Agency a Preferred Shares Basic Maintenance Report as of the close of business on such date that Common Shares are repurchased. If any such letter prepared by the Fund's independent accountants shows that an error was made in the most recent Preferred Shares Basic Maintenance Report, the calculation or determination made by the Fund's independent accountants will be conclusive and binding on the Fund.

Redemption

Optional Redemption

To the extent permitted under the 1940 Act and under Massachusetts law, upon giving a notice of redemption, as provided below, the Fund, at its option, may redeem the Preferred Shares, in whole or in part, out

57

of funds legally available therefor, at the Optional Redemption Price per share on any Dividend Payment Date upon not less than 17 days' and not more than 30 days' prior notice; provided that no Preferred Shares may be redeemed at the option of the Fund during (a) the Initial Dividend Period with respect to the Preferred Shares or (b) a Non-Call Period to which such share is subject. "Optional Redemption Price" means $25,000 per Preferred Share plus an amount equal to accumulated but unpaid dividends (whether or not earned or declared) to the date fixed for redemption plus any applicable redemption premium, if any, attributable to the designation of a Premium Call Period. The Fund has the authority to redeem the Preferred Shares for any reason and may redeem all or part of the outstanding Preferred Shares if it anticipates that the Fund's leveraged capital structure will result in a lower rate of return to holders of Common Shares for any significant period of time than that obtainable if the Common Shares were unleveraged.

Mandatory Redemption

Under the Amended Bylaws, the Fund will be required to redeem, out of funds legally available therefor, at the Mandatory Redemption Price per share, some or all of the Preferred Shares to the extent permitted under the 1940 Act and Massachusetts law, on a date fixed by the Board of Trustees, if the Fund fails to maintain Eligible Assets with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or to satisfy the 1940 Act Preferred Shares Asset Coverage and such failure is not cured on or before the Preferred Shares Basic Maintenance Cure Date or the 1940 Act Cure Date (herein collectively referred to as a "Cure Date"), as the case may be. "Mandatory Redemption Price" for each series of Preferred Shares means $25,000 per share plus an amount equal to accumulated but unpaid dividends (whether or not earned or declared) to (but not including) the date fixed for redemption. The number of Preferred Shares to be redeemed 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 Cure Date, together with all other preferred shares of beneficial interest of the Fund subject to redemption or retirement, would result in the Fund having Moody's Eligible Assets and Fitch Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or satisfaction of the 1940 Act Preferred Shares Asset Coverage, as the case may be, on such Cure Date (provided that, if there is no such minimum number of shares the redemption of which would have such result, all Preferred Shares then outstanding will be redeemed), and (b) the maximum number of Preferred Shares, together with all other preferred shares subject to redemption or retirement, that can be redeemed out of funds expected to be legally available therefor on such redemption date. In determining the number of Preferred Shares required to be redeemed in accordance with the foregoing, the Fund shall allocate the number required to be redeemed which would result in the Fund having Moody's Eligible Assets and Fitch Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or satisfaction of the 1940 Act Preferred Shares Asset Coverage, as the case may be, pro rata among Preferred Shares and other preferred shares of beneficial interest of the Fund subject to redemption pursuant to provisions similar to those set forth below; provided that Preferred Shares that may not be redeemed at the option of the Fund because of the designation of a Non-Call Period applicable to such shares (A) will be subject to mandatory redemption only to the extent that other shares are not available to satisfy the number of shares required to be redeemed and (B) will be selected for redemption in an ascending order of outstanding number of days in the Non-Call Period (with shares with the lowest number of days to be redeemed first) and by lot in the event of shares' having an equal number of days in such Non-Call Period. The Fund is required to effect such a mandatory redemption not later than 35 days after such Cure Date, except that if the Fund does not have funds legally available for the redemption of all of the required number of Preferred Shares which are subject to mandatory redemption or the Fund otherwise is unable to effect such redemption on or prior to 35 days after such Cure Date, the Fund will redeem those Preferred Shares which it was unable to redeem on the earliest practicable date on which it is able to effect such redemption out of funds legally available therefor.

General

If the Preferred Shares are to be redeemed, a notice of redemption will be mailed to each record holder of such Preferred Shares (initially Cede & Co. as nominee of the Securities Depository) and to the Auction Agent

58

not less than 17 nor more than 30 days prior to the date fixed for the redemption thereof. Each notice of redemption will include a statement setting forth: (i) the redemption date, (ii) the aggregate number of Preferred Shares to be redeemed, (iii) the redemption price, (iv) the place or places where Preferred Shares are to be surrendered for payment of the redemption price, (v) a statement that dividends on the shares to be redeemed will cease to accumulate on such redemption date and (vi) the provision of the Amended Bylaws pursuant to which such shares are being redeemed. No defect in the notice of redemption or in the mailing or publication thereof will affect the validity of the redemption proceedings, except as required by applicable law.

If fewer than all of the outstanding Preferred Shares are to be redeemed, the shares to be redeemed will, unless otherwise required by the Fund's Amended Bylaws, be selected by lot or such other method as the Fund deems fair and equitable, and the results thereof will be communicated to the Auction Agent. The Auction Agent will give notice to the Securities Depository, whose nominee will be the record holder of all Preferred Shares, and the Securities Depository will determine the number of shares to be redeemed from the account of the Agent Member of each Existing Holder. Each Agent Member will determine the number of shares to be redeemed from the account of each Existing Holder for which it acts as agent. An Agent Member may select for redemption shares from the accounts of some Existing Holders without selecting for redemption any shares from the accounts of other Existing Holders. Notwithstanding the foregoing, if neither the Securities Depository nor its nominee is the record holder of any series of Preferred Shares to be redeemed, the particular shares in such series to be redeemed shall be selected by the Fund by lot or by such other method as the Fund deems fair and equitable.

If the Fund gives notice of redemption, and concurrently or thereafter deposits in trust with the Auction Agent, or segregates in an account at the Fund's custodian bank for the benefit of the Auction Agent, Deposit Securities (with a right of substitution) having an aggregate Discounted Value equal to the redemption payment for the Preferred Shares as to which notice of redemption has been given, with irrevocable instructions and authority to pay the redemption price to the record holders thereof, then upon the date of such deposit or, if no such deposit is made, upon such date fixed for redemption (unless the Fund defaults in making payment of the redemption price), all rights of the holders of such shares called for redemption will cease and terminate, except the right of such holders to receive the redemption price thereof, but without interest, and such shares no longer will be deemed to be outstanding. The Fund will be entitled to receive, from time to time, the interest, if any, earned on such Deposit Securities deposited with the Auction Agent, and the holders of any shares so redeemed will have no claim to any such interest. Any funds so deposited which are unclaimed at the end of one year from such redemption date will be repaid, upon demand, to the Fund, after which the holders of the Preferred Shares of such series so called for redemption may look only to the Fund for payment thereof.

So long as any Preferred Shares are held of record by the nominee of the Securities Depository (initially Cede & Co.), the redemption price for such shares will be paid on the redemption date to the nominee of the Securities Depository. The Securities Depository's normal procedures now provide for it to distribute the amount of the redemption price to Agent Members who, in turn, are expected to distribute such funds to the persons for whom they are acting as agent.

Notwithstanding the provisions for redemption described above, no Preferred Shares shall be subject to optional redemption unless (i) all dividends in arrears on the outstanding Preferred Shares, and all shares of beneficial interest of the Fund ranking on a parity with the Preferred Shares with respect to the payment of dividends or upon liquidation, have been or are being contemporaneously paid or declared and set aside for payment and (ii) redemption thereof would not result in the Fund's failure to maintain Moody's Eligible Assets and Fitch Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount.

Liquidation Rights

Upon any liquidation, dissolution or winding up of the Fund, whether voluntary or involuntary, the holders of Preferred Shares of each series will be entitled to receive, out of the assets of the Fund available for

distribution to shareholders, before any distribution or payment is made upon any Common Shares or any other shares of beneficial interest of the Fund ranking junior in right of payment upon liquidation of Preferred Shares, $25,000 per share together with the amount of any dividends accumulated but unpaid (whether or not earned or declared) thereon to the date of distribution, and after such payment the holders of Preferred Shares will be entitled to no other payments. If such assets of the Fund are insufficient to make the full liquidation payment on outstanding Preferred Shares and liquidation payments on any other outstanding class or series of preferred shares of the Fund ranking on a parity with the Preferred Shares as to payment upon liquidation, then such assets will be distributed among the holders of Preferred Shares and the holders of shares of such other class or series ratably in proportion to the respective preferential amounts to which they are entitled. After payment of the full amount of the liquidation distribution to which they are entitled, the holders of Preferred Shares will not be entitled to any further participation in any distribution of assets by the Fund. A consolidation, merger or share exchange of the Fund with or into any other entity or entities or a sale, whether for cash, shares of stock, securities or properties, of all or substantially all or any part of the assets of the Fund shall not be deemed or construed to be a liquidation, dissolution or winding up of the Fund.

Voting Rights

Except as otherwise indicated in this prospectus and except as otherwise required by the Declaration, the Amended Bylaws or applicable law, holders of Preferred Shares will be entitled to one vote per share on each matter submitted to a vote of shareholders and will vote together with holders of Common Shares and other preferred shares of beneficial interest of the Fund as a single class.

In connection with the election of the Fund's trustees, holders of the Preferred Shares and any other preferred shares, voting as a separate class, shall be entitled at all times to elect two of the Fund's trustees, and the remaining trustees will be elected by holders of Common Shares and Preferred Shares and any other preferred shares, voting together as a single class. In addition, if at any time dividends on outstanding Preferred Shares are unpaid in an amount equal to at least two full years' dividends thereon and sufficient cash or securities shall not have been deposited with the Auction Agent for the payment of such accumulated dividends, or if at any time holders of any preferred shares are entitled, together with the holders of Preferred Shares, to elect a majority of the trustees of the Fund under the 1940 Act, then the number of trustees constituting the Board of Trustees automatically shall be increased by the smallest number that, when added to the two trustees elected exclusively by the holders of Preferred Shares and any other preferred shares as described above, would constitute a majority of the Board of Trustees as so increased by such smallest number, and at a special meeting of shareholders which will be called and held as soon as practicable, and at all subsequent meetings at which trustees are to be elected until all dividends in arrears have been paid or otherwise provided for, the holders of the Preferred Shares and any other preferred shares, voting as a separate class, will be entitled to elect the smallest number of additional trustees that, together with the two trustees which such holders in any event will be entitled to elect, constitutes a majority of the total number of trustees of the Fund as so increased. The terms of office of the persons who are trustees at the time of that election will continue, unless otherwise terminated pursuant to the Declaration or the Amended Bylaws. If the Fund thereafter shall pay, or declare and set apart for payment in full, all dividends payable on all outstanding Preferred Shares and any other preferred shares for all past Dividend Periods, the additional voting rights of the holders of Preferred Shares and any other preferred shares as described above shall cease, and the terms of office of all of the additional trustees, if any, elected by the holders of Preferred Shares and any other preferred shares (but not of the trustees with respect to whose election the holders of Common Shares were entitled to vote or the two trustees the holders of Preferred Shares and any other preferred shares have the right to elect in any event) will terminate automatically.

The affirmative vote of a majority of the votes entitled to be cast by holders of outstanding Preferred Shares and any other preferred shares, voting together as one class, will be required to (i) authorize, create or issue any class or series of shares of beneficial interest ranking prior to the Preferred Shares or any other series of preferred shares with respect to the payment of dividends or the distribution of assets on liquidation; provided, however, that no vote is required to authorize the issuance of another series of Preferred Shares or another class of

60

preferred shares which are substantially identical in all respects to the Preferred Shares or (ii) amend, alter or repeal the provisions of the Declaration or the Amended Bylaws, whether by merger, consolidation or otherwise, so as to adversely affect any of the contract rights expressly set forth in the Declaration or the Amended Bylaws of holders of Preferred Shares or any other preferred shares. To the extent permitted under the 1940 Act, in the event shares of more than one series of Preferred Shares are outstanding, the Fund shall not approve any of the actions set forth in clause (i) or (ii) which adversely affects the contract rights expressly set forth in the Declaration or the Amended Bylaws of a holder of shares of a series of Preferred Shares differently from those of a holder of shares of any other series of Preferred Shares without the affirmative vote of at least a majority of votes entitled to be cast by holders of the Preferred Shares of each series adversely affected and outstanding at such time (each such adversely affected series voting separately as a class). The Board of Trustees, however, without shareholder approval, may amend, alter or repeal any or all of the various Rating Agency guidelines described herein in the event the Fund receives confirmation from Moody's and Fitch Ratings (or any applicable Substitute Rating Agency) that any such amendment, alteration or repeal would not impair the rating then assigned to the Preferred Shares by such Rating Agency. Unless a higher percentage is provided for under the Declaration or the Amended Bylaws, the affirmative vote of a majority of the votes entitled to be cast by holders of outstanding Preferred Shares and any other preferred shares, voting as a separate class, will be required to approve any plan of reorganization (including bankruptcy proceedings) adversely affecting such shares or any action requiring a vote of security holders under Section 13(a) of the 1940 Act including, among other things, changes in the investment restrictions described as fundamental policies under "Investment Restrictions" in the Statement of Additional Information. To the extent permitted under the 1940 Act, in the event shares of more than one series of Preferred Shares are outstanding, with respect to any action requiring shareholder approval pursuant to the operation of Section 2 or Section 3 of Article V of the Declaration, the affirmative vote of at least seventy-five percent of the Preferred Shares of each series outstanding at such time (each such series voting separately as a class) shall also be required. The class (and, where applicable, series) vote of holders of Preferred Shares and any other preferred shares described above in each case will be in addition to a separate vote of the requisite percentage of Common Shares and Preferred Shares and any other preferred shares, voting together as a single class, necessary to authorize the action in question. See "Anti-Takeover and Other Provisions in the Declaration of Trust."

The foregoing voting provisions will not apply to the Preferred Shares if, at or prior to the time when the act with respect to which such vote otherwise would be required shall be effected, such shares shall have been (i) redeemed or (ii) called for redemption and sufficient funds shall have been deposited in trust to effect such redemption.

MANAGEMENT OF THE FUND

Trustees and Officers

The Board of Trustees is responsible for the management of the Fund, including supervision of the duties performed by the Manager and PIMCO. There are currently three Trustees of the Fund, none of whom is currently treated by the Fund as an "interested person" (as defined in the 1940 Act). 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 Manager

Portfolio Manager

PIMCO serves as the portfolio manager for the Fund. Subject to the supervision of the Manager, PIMCO has full investment discretion and makes all determinations with respect to the investment of the Fund's assets.

PIMCO is located at 840 Newport Center Drive, Newport Beach, California 92660. Organized in 1971, PIMCO provides investment management and advisory services to private accounts of institutional and individual clients and to mutual funds. As of March 31, 2003, PIMCO had approximately $323 billion in assets under management.

The Manager (and not the Fund) will pay a portion of the fees it receives to PIMCO in return for PIMCO's services, at the annual rate of 0.3575% of the Fund's average daily net assets (including assets attributable to any Preferred Shares that may be outstanding) for the period from the commencement of Fund operations through April 31, 2008 (i.e., roughly the first five years of Fund operations) (the "Initial Period") and at the annual rate of 0.50% of such average daily net assets thereafter while the Investment Management Agreement remains in effect (the "Remaining Period"). PIMCO has also agreed to reimburse the Manager for 65% of the fees that the Manager pays to certain underwriters in connection with the offering of the Common Shares.

Bill Gross, a founder of PIMCO, serves as Managing Director and Chief Investment Officer of PIMCO.

Investment Management Agreement

Pursuant to an investment management agreement between the Manager and the Fund (the "Investment Management Agreement"), the Fund has agreed to pay the Manager an annual management fee payable on a monthly basis at the annual rate of 0.70% of the Fund's average daily net assets (including net assets attributable to Preferred Shares) for the services and facilities it provides.

In addition to the fees of the Manager, the Fund pays all other costs and expenses of its operations, including compensation of its Trustees (other than those affiliated with the Manager), custodial expenses, shareholder servicing expenses, transfer agency and dividend disbursing expenses, legal fees, expenses of independent auditors, expenses of repurchasing shares, expenses of issuing any Preferred Shares, expenses of preparing, printing and distributing prospectuses, shareholder reports, notices, proxy statements and reports to governmental agencies, and taxes, if any.

Because the fees received by the Manager are based on the total net assets of the Fund (including assets attributable to Preferred Shares and any leverage created thereby), the Manager has a financial incentive for the Fund to issue Preferred Shares, which may create a conflict of interest between the Manager and the holders of the Common Shares.

63

NET ASSET VALUE

The net asset value ("NAV") of the Fund equals the total value of the Fund's portfolio investments and other assets, less any liabilities. For purposes of calculating NAV, portfolio securities and other assets for which market quotes are available are stated at market value. Market value is generally determined on the basis of the last reported sales price (or the NASDAQ Official Closing Price for NASDAQ-reported securities) or, if no sales are reported, based on quotes obtained from a quotation reporting system, established market makers, or pricing services. Certain securities or investments for which market quotations are not readily available may be valued, pursuant to guidelines established by the Board of Trustees, with reference to other securities or indexes. For instance, a pricing service may recommend a fair market value based on prices of comparable securities. Short-term investments having a maturity of 60 days or less are generally valued at amortized cost. Exchange traded options, futures and options on futures are valued at the settlement price determined by the exchange. Other securities for which market quotes are not readily available are valued at fair value as determined in good faith by the Board of Trustees or persons acting at their direction.

The NAV of the Fund will be determined as of the close of regular trading on the New York Stock Exchange (normally 4:00 p.m., Eastern time) (the "NYSE Close") on each day the New York Stock Exchange is open. Domestic debt securities and foreign securities are normally priced using data reflecting the earlier closing of the principal markets for those securities. Information that becomes known to the Fund or its agent after the Fund's NAV has been calculated on a particular day will not be used to retroactively adjust the price of a security or the Fund's NAV determined earlier that day.

Investments initially valued in currencies other than the U.S. dollar are converted to U.S. dollars using exchange rates obtained from pricing services. As a result, the NAV of the Fund's shares may be affected by changes in the value of currencies in relation to the U.S. dollar. The value of securities traded in markets outside the United States or denominated in currencies other than the U.S. dollar may be affected significantly on a day that the New York Stock Exchange is closed.

In unusual circumstances, instead of valuing securities in the usual manner, the Fund may value securities at fair value as determined in good faith by the Board of Trustees, generally based upon recommendations provided by PIMCO. Fair valuation also may be required because of material events that occur after the close of the relevant market but prior to the NYSE Close.

TAX MATTERS

Federal Income Tax Matters

The following federal income tax discussion is based on the advice of Ropes & Gray LLP, counsel to the Fund, and reflects provisions of the Code, existing Treasury regulations, rulings published by the IRS, and other applicable authority, as of the date of this prospectus. These authorities are subject to change by legislative or administrative action, possibly with retroactive effect. The following discussion is only a summary of some of the important tax considerations generally applicable to investments in the Fund. For more detailed information regarding tax considerations, see the Statement of Additional Information. There may be other tax considerations applicable to particular investors. In addition, income earned through an investment in the Fund may be subject to state, local and foreign taxes.

The Fund intends to qualify each year for taxation as a regulated investment company eligible for treatment under the provisions of Subchapter M of the Code. If the Fund so qualifies and satisfies certain distribution requirements, the Fund will not be subject to federal income tax on income distributed in a timely manner to its shareholders in the form of dividends or capital gain distributions.

64

In order for any portion of any distributions to holders of Preferred Shares to be eligible to be treated as capital gain dividends, the Preferred Shares must be treated as equity for federal income tax purposes. Based in part on certain representations made by the Fund to Ropes & Gray LLP relating to the lack of any present intention to redeem or purchase Preferred Shares at any time in the future, it is the opinion of Ropes & Gray LLP that the Preferred Shares will constitute equity for federal income tax purposes. This opinion relies in part on a published ruling of the IRS stating that certain auction rate preferred stock similar in many material respects to the Preferred Shares represents equity. The opinion of Ropes & Gray LLP represents only its best legal judgment and is not binding on the IRS or the courts. If the IRS were to assert successfully that variable rate preferred stock such as the Preferred Shares should be treated as debt for federal income tax purposes, distributions on Preferred Shares (including distributions designated by the Fund as capital gain dividends) would be taxable as ordinary income (as opposed to capital gains). Ropes & Gray LLP has advised the Fund that, should the IRS pursue in court the position that the Preferred Shares should be treated as debt for federal income tax purposes, the IRS would be unlikely to prevail.

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) based upon the percentage of total dividends distributed to each class for the tax year. Accordingly, the Fund intends each year to allocate capital gain dividends between and among its Common Shares and any series of its Preferred Shares in proportion to the total dividends paid to each class with respect to such tax year. Dividends qualifying and not qualifying for (a) treatment as qualified dividend income and (b) the dividends received deduction, if any, will similarly be allocated between and among any such classes.

Existing authorities do not specifically address whether dividends that are paid following the close of a taxable year, but that are treated for tax purposes as derived from the income of such prior taxable year, are treated as dividends paid during such prior taxable year for purposes of determining each class's proportionate share of a particular type of income. The Fund currently intends to treat such dividends as having been paid in the prior taxable year for purposes of determining each class's proportionate share of a particular type of income with respect to such prior taxable year. Existing authorities also do not specifically address the allocation of taxable income among the dividends paid to holders of a class of shares during or with respect to a taxable year. It is possible that the IRS could disagree with the Fund's position concerning the treatment of dividends paid after the close of a taxable year or with the Fund's method of allocation, in which case the IRS could attempt to recharacterize a portion of the dividends paid to the holders of Preferred Shares. If the IRS were to prevail with respect to any such attempted recharacterization, holders of Preferred Shares could be subject to additional tax on amounts so recharacterized and the Fund could be subject to federal income and excise tax.

To satisfy the distribution requirement applicable to regulated investment companies, amounts paid as dividends by the Fund to its shareholders, including holders of Preferred Shares, must qualify for the dividends-paid deduction. In certain circumstances, the IRS could take the position that dividends paid on the Preferred Shares constitute preferential dividends under Section 562(c) of the Code, and thus do not qualify for the dividends-paid deduction. The Fund believes this position, if asserted, would be unlikely to prevail.

If at any time when Preferred Shares are outstanding the Fund does not meet applicable asset coverage requirements, it will be required to suspend distributions to Common Shareholders until the requisite asset coverage is restored. Any such suspension may cause the Fund to pay a 4% federal excise tax (imposed on regulated investment companies that fail to distribute for a given calendar year, generally, at least 98% of their net investment income and capital gain net income) and income tax on undistributed income or gains, and may, in certain circumstances, prevent the Fund from qualifying for treatment as a regulated investment company. The Fund may redeem Preferred Shares in an effort to comply with the distribution requirement applicable to regulated investment companies and to avoid income and excise taxes. The Fund may have to dispose of portfolio securities to generate cash for such redemptions, which may result in transaction expenses and gain at the Fund level and in further distributions.

65

The Fund's investments in certain debt obligations may cause the Fund to recognize taxable income in excess of the cash generated by such obligations. Thus, the Fund could be required at times to liquidate other investments in order to satisfy its distribution requirements.

For federal income tax purposes, distributions of investment income are generally taxable as ordinary income. Taxes on distributions of capital gains are determined by how long the Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares. Distributions of net capital gains from the sale of investments that the Fund owned for more than one year and that are properly designated by the Fund as capital gain dividends will be taxable as long-term capital gains. Distributions of gains from the sale of investments that the Fund owned for one year or less will be taxable as ordinary income. For taxable years beginning on or before December 31, 2008, distributions of investment income designated by the Fund as derived from qualified dividend income will be taxed in the hands of individuals at the rates applicable to long-term capital gain provided holding period and other requirements are met at both the shareholder and Fund levels. The Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

Distributions are taxable to shareholders even if they are paid from income or gains earned by the Fund before a shareholder's investment (and thus were included in the price the shareholder paid). Any gain resulting from the sale or exchange of Fund shares generally will be taxable as capital gains.

Long-term capital gain rates applicable to individuals have been temporarily reduced--in general, to 15% with lower rates applying to taxpayers in the 10% and 15% rate brackets--for taxable years beginning on or before December 31, 2008.

The Fund's investments in foreign securities may be subject to foreign withholding taxes. In that case, the Fund's yield on those securities would be decreased. Shareholders generally will not be entitled to claim a credit or deduction with respect to foreign taxes. In addition, the Fund's investments in foreign securities or foreign currencies may increase or accelerate the Fund's recognition of ordinary income and may affect the timing or amount of the Fund's distributions.

Under current law, the backup withholding tax rate is 28% for amounts paid through 2010 and will be 31% for amounts paid after December 31, 2010. The Fund may be required to apply backup withholding to taxable distributions or redemption proceeds payable to a shareholder. Please see "Tax Matters" in the Statement of Additional Information for additional information about backup withholding tax rates.

If, in connection with the designation of a Special Dividend Period, (i) the Fund provides in a Notice of Special Dividend Period that the Fund may redeem all or part of a series of Preferred Shares and that upon such redemption the holders of that series of Preferred Shares may receive a premium in addition to receipt of a redemption price per share equal to the sum of $25,000 plus an amount equal to the accumulated but unpaid dividends thereon during the whole or any part of the Special Dividend Period, (ii) based on all the facts and circumstances at the time of the designation of the Special Dividend Period the Fund is more likely than not to redeem such series of Preferred Shares during the Special Dividend Period, and (iii) the premium to be paid upon redemption during such Special Dividend Period exceeds a specified de minimis amount, it is possible that the holders of such series will be required to accrue the premium as a dividend (to the extent of the Fund's earnings and profits).

This section relates only to federal income tax consequences of investing in the Fund; the consequences under other tax laws may differ. You should consult your tax adviser as to the possible application of foreign, state and local income tax laws to Fund distributions. Please see "Tax Matters" in the Statement of Additional Information for additional information regarding the tax aspects of investing in the Fund.

DESCRIPTION OF CAPITAL STRUCTURE

The Fund is an unincorporated business trust established under the laws of The Commonwealth of Massachusetts by the Declaration. The Declaration provides that the Board of Trustees of the Fund may authorize separate classes of shares of beneficial interest. The Board of Trustees has authorized an unlimited number of common shares of beneficial interest and preferred shares of beneficial interest. Preferred shares (such as the Preferred Shares) may be issued in one or more series, with such par value and with such rights as determined by the Board of Trustees, by action of the Board of Trustees without the approval of the Common Shareholders. For a description of the Preferred Shares, see "Description of Preferred Shares." The following table shows the amount of (i) shares authorized and (ii) shares outstanding, for each class of authorized securities of the Fund as of June 11, 2003.

                   Amount     Amount

* Assumes the authorization of 36,000 Preferred Shares by the Board of Trustees prior to the issuance of the Preferred Shares.

Holders of Common Shares are entitled to share equally in dividends declared by the Board of Trustees payable to holders of Common Shares and in the net assets of the Fund available for distribution to holders of Common Shares after payment of the preferential amounts payable to holders of any outstanding preferred shares of beneficial interest. Neither holders of Common Shares nor holders of preferred shares have pre-emptive or conversion rights or give shareholders the right to cause the Fund to redeem their shares. Upon liquidation of the Fund, after paying or adequately providing for the payment of all liabilities of the Fund and the liquidation preference with respect to any outstanding preferred shares, and upon receipt of such releases, indemnities and refunding agreements as they deem necessary for their protection, the Trustees may distribute the remaining assets of the Fund among the holders of the Common Shares.

Pursuant to the Fund's Dividend Reinvestment Plan, all Common Shareholders whose shares are registered in their own names will have all dividends, including any capital gain dividends, reinvested automatically in additional Common Shares by PFPC Inc., as agent for the Common Shareholders, unless the shareholder elects to receive cash. The Fund and PFPC Inc. reserve the right to amend or terminate the Dividend Reinvestment Plan.

Holders of Common Shares are entitled to one vote for each share held and will vote with the holders of any outstanding Preferred Shares or other preferred shares on each matter submitted to a vote of holders of Common Shares, except as described under "Description of Preferred Shares--Voting Rights" and except as otherwise required by the Declaration, the Amended Bylaws or applicable law.

Preferred shareholders are entitled to one vote for each share held. Except as provided under "Description of Preferred Shares--Voting Rights" and except as otherwise required by the Declaration, the Amended Bylaws or applicable law, holders of Preferred Shares are (voting as a separate class) entitled to elect two trustees, and the remaining trustees shall be elected by holders of Common Shares and Preferred Shares, voting as a single class.

So long as any Preferred Shares or any other preferred shares are outstanding, holders of Common Shares will not be entitled to receive any dividends of or other distributions from the Fund, unless at the time of such declaration, (1) all accrued dividends on Preferred Shares or accrued interest on borrowings has been paid and (2)

67

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

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

Common Shares of the Fund commenced trading on the New York Stock Exchange on April 25, 2003. At June 11, 2003, the net asset value per share of Common Shares was $14.77, and the closing price per share of Common Shares on the New York Stock Exchange was $15.11. The Fund intends to hold annual meetings of shareholders so long as the Common Shares are listed on a national securities exchange and such meetings are required as a condition to such listing.

Other Issues Relating to Preferred Shares

Under the 1940 Act, the Fund is permitted to have outstanding more than one series of preferred shares of beneficial interest as long as no single series has priority over another series as to the distribution of assets of the Fund or the payment of dividends. Neither holders of Common Shares nor holders of preferred shares have pre-emptive rights to purchase any Preferred Shares or any other preferred shares that might be issued. It is anticipated that the net asset value per Preferred Share will equal its original purchase price per share plus accumulated dividends per share.

ANTI-TAKEOVER AND OTHER PROVISIONS IN THE DECLARATION OF TRUST

The Declaration includes provisions that could limit the ability of other entities or persons to acquire control of the Fund or to convert the Fund to open-end status. The Fund's Trustees are divided into three classes. At each annual meeting of shareholders, the term of one class will expire and each Trustee elected to that class will hold office for a term of three years. The classification of the Board of Trustees in this manner could delay for an additional year the replacement of a majority of the Board of Trustees. In addition, the Declaration provides that a Trustee may be removed only for cause and only (i) by action of at least seventy-five percent (75%) of the outstanding shares of the classes or series of shares entitled to vote for the election of such Trustee, or (ii) by at least seventy-five percent (75%) of the remaining Trustees.

As described below, the Declaration grants special approval rights with respect to certain matters to members of the Board who qualify as "Continuing Trustees," which term means a Trustee who either (i) has been a member of the Board for a period of at least thirty-six months (or since the commencement of the Fund's operations, if less than thirty-six months) or (ii) was nominated to serve as a member of the Board of Trustees by a majority of the Continuing Trustees then members of the Board.

The Declaration requires the affirmative vote or consent of at least seventy-five percent (75%) of the Board of Trustees and holders of at least seventy-five percent (75%) of the Fund's shares (including Common and Preferred Shares) to authorize certain Fund transactions not in the ordinary course of business, including a merger or consolidation, issuance or transfer by the Fund of the Fund's shares (except as may be pursuant to a public offering or the Fund's dividend reinvestment plan or upon exercise of any stock subscription rights), a

68

sale, transfer or other disposition of Fund assets, or any shareholder proposal regarding specific investment decisions, unless the transaction is authorized by both a majority of the Trustees and seventy-five percent (75%) of the Continuing Trustees (in which case no shareholder authorization would be required by the Declaration, but might be required in certain cases under the 1940 Act). The Declaration also requires the affirmative vote or consent of holders of at least seventy-five percent (75%) of each class of the Fund's shares entitled to vote on the matter to authorize a conversion of the Fund from a closed-end to an open-end investment company, unless the conversion is authorized by both a majority of the Trustees and seventy-five percent (75%) of the Continuing Trustees (in which case shareholders would have only the minimum voting rights required by the 1940 Act with respect to the conversion). Also, the Declaration provides that the Fund may be terminated at any time by vote or consent of at least seventy-five percent (75%) of the Fund's shares or, alternatively, by vote or consent of both a majority of the Trustees and seventy-five percent (75%) of the Continuing Trustees. See "Anti-Takeover and Other Provisions in the Declaration of Trust" in the Statement of Additional Information for a more detailed summary of these provisions.

The Trustees may from time to time grant other voting rights to shareholders with respect to these and other matters in the Amended Bylaws, certain of which are required by the 1940 Act. For example, the Amended Bylaws grant holders of Preferred Shares and any other preferred shares special voting rights with respect to certain matters described in the preceding paragraph. See "Description of Preferred Shares--Voting Rights."

The overall effect of these provisions is to render more difficult the accomplishment of a merger or the assumption of control of the Fund by a third party. They provide, however, 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 objectives and policies. The provisions of the Declaration described above could have the effect of discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. The Board of Trustees of the Fund has considered the foregoing anti-takeover provisions and concluded that they are in the best interests of the Fund.

The foregoing is intended only as a summary and is qualified in its entirety by reference to the full text of the Declaration and the Amended Bylaws, both of which are on file with the Securities and Exchange Commission.

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

REPURCHASE OF COMMON SHARES; CONVERSION TO OPEN-END FUND

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. Shares of a closed-end investment company may frequently trade at prices lower than net asset value. The Board of Trustees regularly monitors the relationship between the market price and net asset value of the Common Shares. If the Common Shares were to trade at a substantial discount to net asset value for an extended period of time, the Board may consider the repurchase of its Common Shares on the open market or in private transactions, the making of a tender offer for such shares, or the conversion of the Fund to an open-end investment company. The Fund cannot assure you that the Board of Trustees will decide to take or propose any of these actions.

69

If the Fund were to convert to an open-end company, it would be required to redeem all preferred shares (including the Preferred Shares) then outstanding (requiring in turn that it liquidate a portion of its investment portfolio), and the Common Shares would no longer be listed on the New York Stock Exchange. In contrast to shareholders of a closed-end investment company, shareholders of an open-end investment company may require the company to redeem their shares at any time (except in certain circumstances as authorized by or under the 1940 Act) at their net asset value, less any redemption charge that is in effect at the time of redemption.

Before deciding whether to take any action to convert the Fund to an open-end investment company, the Board of Trustees would 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. See the Statement of Additional Information under "Repurchase of Common Shares; Conversion to Open-End Fund" for a further discussion of possible action to reduce or eliminate such discount to net asset value.

The underwriting agreement provides that the obligations of the Underwriters to purchase the Preferred Shares included in this offering are subject to approval of legal matters by counsel and to other conditions. 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 dealers at the public offering price less a concession not to exceed $137.50 per Preferred Share. The sales load the Fund will pay of $250 per share is equal to 1.0% of the initial offering price. The Underwriters may allow, and such dealers may reallow, a concession not to exceed $37.50 per Preferred Share on sales to certain other dealers. After the initial public offering, the Underwriters may change the public offering price and the other selling terms. Investors must pay for any Preferred Shares purchased on or before June 26, 2003.

The Fund and the Manager have each agreed to indemnify the several Underwriters or contribute to losses arising out of certain liabilities, including liabilities under the Securities Act.

In addition, the Fund has agreed to reimburse the Underwriters for certain expenses incurred by the Underwriters in the offering.

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

70

anticipates that the Underwriters or their respective affiliates may from time to time act in auctions as Broker-Dealers and receive fees as described under "Description of Preferred Shares." The Underwriters are active underwriters of, and dealers in, securities and act as market makers in a number of such securities, and therefore, subject to certain restrictions, can be expected to engage in portfolio transactions with, and perform services for, the Fund.

                                                            Fitch Rating Category

/1/ If a security is not rated by Fitch Ratings but is rated by two other NRSROs, then the lower of the ratings on the security from the two other NRSROs 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings but is rated by only one other NRSRO, then the rating on the security from the other NRSRO 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 rating by Fitch Ratings of AAA- will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings of BB- will be used). If a security is not rated by any NRSRO, the Fund will use the percentage set forth under "Not Rated or Below BBB" in this table.

The Fitch Discount Factors presented in the immediately preceding table apply to Debt Securities that are Performing and have a Market Value determined by a Pricing Service or an Approved Price. The Fitch Discount Factor noted in the table above for a Debt Security not rated or rated below BB by Fitch Ratings shall apply to any non-Performing Debt Security with a price equal to or greater than $0.20. If a Debt Security does not have a Market Value determined by a Pricing Service or an Approved Price, a rating one rating category below the actual rating on the Debt Security will be used (e.g., where the actual rating is A-, the rating for Debt Securities rated BBB- will be used). The Fitch Discount Factor for a Debt Security issued by a limited partnership that is not a Rule 144A Security shall be the Discount Factor determined in accordance with the table set forth above multiplied by 105%.

The Fitch Discount Factors presented in the immediately preceding table will also apply to (i) interest rate swaps and caps, whereby the rating of the counterparty to the swap or cap will be the rating used to determine the Fitch Discount Factor in the table; and (ii) TRACERs and TRAINs, whereby the ratings in the table will be applied to the underlying securities and the Market Value of each underlying security will be its proportionate amount of the Market Value of the TRACER or TRAIN. The Fitch Discount Factors presented in the immediately preceding table will also apply to corporate obligations backed by a guaranty, a letter of credit or insurance issued by a third party. If the third-party credit rating is the basis for the rating on the obligation, then the rating on the third party will be used to determine the Fitch Discount Factor in the table. The Fitch Discount Factors presented in the immediately preceding table will also apply to preferred trust certificates, the rating on which will be determined by the underlying debt instruments in the trust, unless such preferred trust certificates are determined by Fitch Ratings to qualify for a traditional equity discount factor, in which case the Fitch Discount Factor shall be 370%.

(ii) Preferred shares:

Preferred Shares                                  Discount Factor

Not rated or below Investment Grade DRD Preferred       200%/1/


/1/ If a security is not rated by Fitch Ratings but is rated by two other NRSROs, then the lower of the ratings on the security from the two other NRSROs 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings but is rated by only one other NRSRO, then the rating on the security from the other NRSRO 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 rating by Fitch Rating of AAA- will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings of BB- will be used). If a security is not rated by any NRSRO, the Fund will use the percentage set forth under "Not rated or below Investment Grade DRD Preferred" in this table.

(iii) Short-term instruments: The Fitch Discount Factor applied to short-term portfolio securities, including without limitation Debt Securities with terms to maturity of one year or less, Short Term Money Market Instruments and municipal debt obligations with terms to maturity within the Fitch Exposure Period, 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 neither mature nor have a demand feature exercisable at par within the Fitch Exposure Period; and (C) 125%, so long as such portfolio securities neither mature within the Fitch Exposure Period nor have a demand feature at par. A Fitch Discount Factor of 100% will be applied to cash.

(v) Convertible Debt Securities: The Fitch Discount Factor applied to convertible debt securities will be (a) 200% for investment grade convertibles and (b) 222% for below investment grade convertibles so long as such convertible debt securities have neither (x) a conversion premium greater than 100% nor (y) a yield to maturity or yield to worst of greater than 15.00% above the corresponding Treasury curve.

The Fitch Discount Factor applied to convertible debt securities which have conversion premiums of greater than 100% will be (a) 152% for investment grade convertibles and (b) 179% for below investment grade convertibles so long as such convertible debt securities do not have a yield to maturity or yield to worst of greater than 15.00% above the corresponding Treasury curve.

77

The Fitch Discount Factor applied to convertible debt securities which have a yield to maturity or yield to worst of greater than 15.00% above the corresponding Treasury curve will be 370%.

If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of AAA will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings of BB- will be used). If a security is not rated by any rating agency, the Fund will treat the security as if it were below investment grade.

/1/ If a security is not rated by Fitch Ratings, but is rated by two other NRSROs, then the lower of the ratings on the security from the two other NRSROs 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings, but is rated by only one other NRSRO, then the rating on the security from the other NRSRO 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 rating by Fitch Ratings of AAA will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings of BB- will be used). If a security is not rated by any NRSRO, the Fund will treat the security as if it were below investment grade.

(x) Municipal debt obligations: The Fitch Discount Factor applied to municipal debt obligations will be the percentage determined by reference to the table set forth below:

Where the Fund 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 Fund 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 Fund purchases an asset and agrees to sell it to a third party in the future, cash receivable by the Fund thereby will constitute a Fitch Eligible Asset if the long-term debt of such other party is rated at least A by Fitch Ratings or the equivalent by another NRSRO and if such agreement has a term of 30 days or less; otherwise the Discounted Value of such purchased asset will constitute a Fitch Eligible Asset.

82

Notwithstanding the foregoing, an asset will not be considered a Fitch Eligible Asset to the extent that it has been irrevocably deposited for the payment of (i)(A) through (i)(E) under the definition of Preferred Shares Basic Maintenance Amount or to the extent it is subject to any Liens, except for (A) Liens which are being contested in good faith by appropriate proceedings and which Fitch Ratings has indicated to the Fund will not affect the status of such asset as a Fitch Eligible Asset, (B) Liens for taxes that are not then due and payable or that can be paid thereafter without penalty, (C) Liens to secure payment for services rendered or cash advanced to the Fund by its investment manager or portfolio manager, the Fund's custodian, transfer agent or registrar or the Auction Agent and (D) Liens arising by virtue of any repurchase agreement.

(ii) the Fund will not engage in any Fitch Hedging Transaction based on Treasury Bonds (other than Closing Transactions) that would cause the Fund at the time of such transaction to own or have sold:

(A) outstanding financial futures contracts based on Treasury Bonds with such contracts having an aggregate Market Value exceeding 20% of the aggregate Market Value of Fitch Eligible Assets owned by the Fund and rated at least AA by Fitch Ratings (or, if not rated by Fitch Ratings, rated at least Aa by Moody's or, if not rated by Moody's, rated AAA by S&P); or

(B) outstanding financial futures contracts based on Treasury Bonds with such contracts having an aggregate Market Value exceeding 40% of the aggregate Market Value of all Fitch Eligible Assets owned by the Fund (other than Fitch Eligible Assets already subject to a Fitch Hedging Transaction) and rated at least A or BBB by Fitch Ratings (or, if not rated by Fitch Ratings, rated at least Baa by Moody's or, if not rated by Moody's, rated at least A or AA by S&P)

"Fitch Loan Category" means the following four categories (and, for purposes of this categorization, the Market Value of a Fitch Eligible Asset trading at par is equal to $1.00):

(i) "Fitch Loan Category A"-- means Performing Bank Loans which have a Market Value or an Approved Price greater than or equal to $0.90.

(ii) "Fitch Loan Category B"-- means: (A) Performing Bank Loans which have a Market Value or an Approved Price greater than or equal to $0.80 but less than $0.90; and (B) non-Performing Bank Loans which have a Market Value or an Approved Price greater than or equal to $0.85.

(C) Performing Bank Loans without an Approved Price rated BB- or higher by Fitch Ratings. If a security is

84

not rated by Fitch Ratings but is rated by two other NRSROs, then the lower of the ratings on the security from the two other NRSROs 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings but is rated by only one other NRSRO, then the rating on the security from the other NRSRO 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 rating by Fitch Ratings of AAA- will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings of BB- will be used).

(iv) "Fitch Loan Category D"-- means Bank Loans not described in any of the foregoing categories.

Notwithstanding any other provision contained above, for purposes of determining whether a Fitch Eligible Asset falls within a specific Fitch Loan Category, to the extent that any Fitch Eligible Asset would fall in more than one of the Fitch Loan Categories, such Fitch Eligible Asset shall be deemed to fall into the Fitch Loan Category with the lowest applicable Fitch Discount Factor.

/1/ Unless conclusions regarding liquidity risk as well as estimates of both the probability and severity of default for the Fund's assets can be derived from other sources as well as combined with a number of sources as presented by the Fund to Moody's, securities rated below B by Moody's and unrated securities, which are securities rated by neither Moody's, S&P nor Fitch Ratings, are limited to 10% of Moody's Eligible Assets. If a corporate debt security is unrated by Moody's, S&P and Fitch Ratings, the Fund will use the percentage set forth under "Below B and Unrated" in this table. Ratings assigned by S&P or Fitch Ratings are generally accepted by Moody's at face value. However, adjustments to face value may be made to particular categories of credits for which the rating by S&P and/or Fitch Ratings does not seem to approximate a Moody's rating equivalent.

The Moody's Discount Factors presented in the immediately preceding table will also apply to Moody's Eligible Assets that are FHLB, FNMA and FFCB Debentures and to rated TRACERs and TRAINs, whereby the ratings in the table will be applied to the underlying securities and the Market Value of each underlying security

86

will be its proportionate amount of the Market Value of the TRACER or TRAIN, provided that the Moody's Discount Factors determined from the table shall be multiplied by a factor of 120% for purposes of calculating the Discounted Value of TRAINs. The Moody's Discount Factors presented in the immediately preceding table will also apply to corporate debt securities that do not pay interest in U.S. dollars or euros, provided that the Moody's Discount Factor determined from the table shall be multiplied by a factor of 110% for purposes of calculating the Discounted Value of such securities.

(ii) Preferred stock: The Moody's Discount Factor for preferred stock shall be (A) for preferred stocks issued by a utility, 155%; (B) for preferred stocks of industrial and financial issuers, 209%; and (C) for auction rate preferred stocks, 350%.

(iii) Short-term instruments: The Moody's Discount Factor applied to short-term portfolio securities, including without limitation corporate debt securities, Short Term Money Market Instruments and municipal debt obligations, will be (A) 100%, so long as such portfolio securities mature within the Moody's Exposure Period or have a demand feature at par exercisable within the Moody's Exposure Period; (B) 115%, so long as such portfolio securities do not mature or have a demand feature at par not exercisable within the Moody's Exposure Period; and (C) 125%, if such securities are not rated by Moody's, so long as such portfolio securities are rated at least A-1+/AA or SP-1+/AA by S&P and mature or have a demand feature at par exercisable within the Moody's Exposure Period. A Moody's Discount Factor of 100% will be applied to cash.

(iv) U.S. Government Securities and U.S. Treasury Strips:

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

94

result, that could be achieved by an investment, consistent with the Fund's investment objectives and policies, in a security that is not an option or futures transaction, and (B) will not write any call options or sell any financial futures contracts for the purpose of hedging the anticipated purchase of an asset prior to completion of such purchase; and

High Quality Debt Securities are those rated in one of the two highest rating categories (the highest category for commercial paper) or, if unrated, deemed comparable by PIMCO.

Investment Grade Debt Securities are those rated in one of the four highest rating categories or, if unrated, deemed comparable by PIMCO.

Below Investment Grade, High Yield Securities ("Junk Bonds") are those rated lower than Baa by Moody's or BBB by S&P and comparable securities. They are deemed predominantly speculative with respect to the issuer's ability to repay principal and interest.

Following is a description of the rating categories of Moody's, S&P and Fitch Ratings applicable to debt securities.

Moody's Investors Service, Inc.

Corporate and Municipal Bond Ratings

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

Aa: Bonds which are rated Aa are judged to be of high quality by all standards. Together with the Aaa group they comprise what are generally known as high-grade bonds. They are rated lower than the best bonds because margins of protection may not be as large as in Aaa securities or fluctuation of protective elements may be of greater amplitude or there may be other elements present that make the long-term risks appear somewhat larger than with Aaa securities.

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

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

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

B: Bonds which are rated B generally lack characteristics of a 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.

A-1

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

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

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

Moody's bond ratings, where specified, are applicable to financial contracts, senior bank obligations and insurance company senior policyholder and claims obligations with an original maturity in excess of one year. Obligations relying upon support mechanisms such as letter-of-credit and bonds of indemnity are excluded unless explicitly rated. Obligations of a branch of a bank are considered to be domiciled in the country in which the branch is located.

Unless noted as an exception, Moody's rating on a bank's ability to repay senior obligations extends only to branches located in countries which carry a Moody's Sovereign Rating for Bank Deposits. Such branch obligations are rated at the lower of the bank's rating or Moody's Sovereign Rating for the Bank Deposits for the country in which the branch is located. When the currency in which an obligation is denominated is not the same as the currency of the country in which the obligation is domiciled, Moody's ratings do not incorporate an opinion as to whether payment of the obligation will be affected by the actions of the government controlling the currency of denomination. In addition, risk associated with bilateral conflicts between an investor's home country and either the issuer's home country or the country where an issuer branch is located are not incorporated into Moody's ratings.

Moody's makes no representation that rated bank obligations or insurance company obligations are exempt from registration under the U.S. Securities Act of 1933 or issued in conformity with any other applicable law or regulation. Nor does Moody's represent any specific bank or insurance company obligation is legally enforceable or a valid senior obligation of a rated issuer.

Moody's applies numerical modifiers, 1, 2, and 3 in each generic rating classified from Aa through Caa in its corporate bond rating system. The modifier 1 indicates that the security ranks in the higher end of its generic rating category; the modifier 2 indicates a mid-range ranking; and the modifier 3 indicates that the issue ranks in the lower end of its generic rating category.

Corporate Short-Term Debt Ratings

Moody's short-term debt ratings are opinions of the ability of issuers to repay punctually senior debt obligations. These obligations have an original maturity not exceeding one year, unless explicitly noted.

Moody's employs the following three 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; and well-established access to a range of financial markets and assured sources of alternate liquidity.

PRIME-2: Issuers rated Prime-2 (or supporting institutions) have a strong ability for repayment of senior short-term debt obligations. This will normally be evidenced by many of the characteristics cited above but to a

A-2

lesser degree. Earnings trends and coverage ratios, while sound, may be more subject to variation. Capitalization characteristics, while still appropriate, may be more affected by external conditions. Ample alternate liquidity is maintained.

PRIME-3: Issuers rated Prime-3 (or supporting institutions) 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.

Short-Term Loans

MIG 1/VMIG 1: This designation denotes superior credit quality. Excellent protection is afforded by established cash flows, highly reliable liquidity support, or demonstrated broad-based access to the market for refinancing.
MIG 2/VMIG 2: This designation denotes strong credit quality. Margins of protection are ample, although not as large as in the preceding group.
MIG 3/VMIG 3: This designation denotes acceptable credit quality. Liquidity and cash-flow protection may be narrow, and market access for refinancing is likely to be less well-established. SG: This designation denotes speculative-grade credit quality. Debt instruments in this category may lack sufficient margins of protection.

Standard & Poor's Ratings Services

Issue Credit Rating Definitions

A Standard & Poor's issue credit rating is a current opinion of the creditworthiness of an obligor with respect to a specific financial obligation, a specific class of financial obligations, or a specific financial program (including ratings on medium term note programs and commercial paper programs). It takes into consideration the creditworthiness of guarantors, insurers, or other forms of credit enhancement on the obligation and takes into account the currency in which the obligation is denominated. The issue credit rating is not a recommendation to purchase, sell, or hold a financial obligation, inasmuch as it does not comment as to market price or suitability for a particular investor.

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

Issue credit ratings can be either long-term or short-term. Short-term ratings are generally assigned to those obligations considered short term in the relevant market. In the U.S., for example, that means obligations with an original maturity of no more than 365 days--including commercial paper. Short-term ratings are also used to indicate the creditworthiness of an obligor with respect to put features on long-term obligations. The result is a dual rating, in which the short-term rating addresses the put feature, in addition to the usual long-term rating. Medium-term notes are assigned long-term 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.

A-3

The issue rating definitions are expressed in terms of default risk. As such, they pertain to senior obligations of an entity. Junior obligations are typically rated lower than senior obligations, to reflect the lower priority in bankruptcy, as noted above. (Such differentiation applies when an entity has both senior and subordinated obligations, secured and unsecured obligations, or operating company and holding company obligations.) Accordingly, in the case of junior debt, the rating may not conform exactly with the category definition.

Corporate and Municipal Bond Ratings

Investment Grade

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.

Speculative Grade

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

A-4

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

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.

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.

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

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. Examples include:
obligations linked or indexed to equities, currencies, or commodities; obligations exposed to severe prepayment risk--such as interest-only or principal-only mortgage securities; and obligations with unusually risky interest terms, such as inverse floaters.

The absence of an "r" symbol should not be taken as an indication that an obligation will exhibit no volatility or variability in total return.

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.

Debt obligations of issuers outside the United States and its territories are rated on the same basis as domestic corporate and municipal issues. The ratings measure the creditworthiness of the obligor but do not take into account currency exchange and related uncertainties.

Commercial Paper Rating Definitions

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

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

A-5

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.

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

Fitch Ratings

AAA

Highest credit quality. 'AAA' ratings denote the lowest expectation of credit risk. They are assigned only in case of exceptionally strong capacity for timely payment of financial commitments. This capacity is highly unlikely to be adversely affected by foreseeable events.

AA

Very high credit quality. 'AA' ratings denote a very low expectation of credit risk. They indicate very strong capacity for timely payment of financial commitments. This capacity is not significantly vulnerable to foreseeable events.

A High credit quality. 'A' ratings denote a low expectation of credit risk. The capacity for timely payment of financial commitments is considered strong. This capacity may, nevertheless, be more vulnerable to changes in circumstances or in economic conditions than is the case for higher ratings.

BBB

Good credit quality. 'BBB' ratings indicate that there is currently a low expectation of credit risk. The capacity for timely payment of financial commitments is considered adequate, but adverse changes in circumstances and in economic conditions are more likely to impair this capacity. This is the lowest investment-grade category.

BB

Speculative. 'BB' ratings indicate that there is a possibility of credit risk developing, particularly as the result of adverse economic change over time; however, business or financial alternatives may be available to allow financial commitments to be met. Securities rated in this category are not investment grade.

B Highly speculative. 'B' ratings indicate that significant credit risk is present, but a limited margin of safety remains. Financial commitments are currently being met; however, capacity for continued payment is contingent upon a sustained, favorable business and economic environment.

A-6

CCC, CC, C

High default risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon sustained, favorable business or economic developments. A 'CC' rating indicates that default of some kind appears probable. 'C' ratings signal imminent default.

DDD, DD, D

Default. The ratings of obligations in this category are based on their prospects for achieving partial or full recovery in a reorganization or liquidation of the obligor. While expected recovery values are highly speculative and cannot be estimated with any precision, the following serve as general guidelines. 'DDD' obligations have the highest potential for recovery, around 90%-100% of outstanding amounts and accrued interest. 'DD' indicates potential recoveries in the range of 50%-90% and 'D' the lowest recovery potential, i.e., below 50%.

Entities rated in this category have defaulted on some or all of their obligations. Entities rated 'DDD' have the highest prospect for resumption of performance or continued operation with or without a formal reorganization process. Entities rated 'DD' and 'D' are generally undergoing a formal reorganization or liquidation process; those rated 'DD' are likely to satisfy a higher portion of their outstanding obligations, while entities rated 'D' have a poor prospect of repaying all obligations.

Short-Term Ratings

The following ratings scale applies to foreign currency and local currency ratings. A short-term rating has a time horizon of less than 12 months for most obligations, or up to three years for U.S. public finance securities, and thus places greater emphasis on the liquidity necessary to meet financial commitments in a timely manner.

F1

Highest credit quality. Indicates the strongest capacity for timely payment of financial commitments; may have an added "+" to denote any exceptionally strong credit feature.

F2

Good credit quality. A satisfactory capacity for timely payment of financial commitments, but the margin of safety is not as great as in the case of the higher ratings.

F3

Fair credit quality. The capacity for timely payment of financial commitments is adequate; however, near-term adverse changes could result in a reduction to non-investment grade.

B Speculative. Minimal capacity for timely payment of financial commitments, plus vulnerability to near-term adverse changes in financial and economic conditions.

C High default risk. Default is a real possibility. Capacity for meeting financial commitments is solely reliant upon a sustained, favorable business and economic environment.

D Default. Denotes actual or imminent payment default.

USE OF PROCEEDS

The net proceeds of the offering of Preferred Shares of the Fund will be approximately $890,400,000 after payment of offering costs and the sales load.

Pending investment in U.S. dollar-denominated debt obligations and other securities that meet the Fund's investment objectives and policies, it is anticipated that the net proceeds of the offering will be invested in high quality, short-term securities.

INVESTMENT OBJECTIVES AND POLICIES

The investment objectives and general investment policies of the Fund are described in the Prospectus. Additional information concerning the characteristics of certain of the Fund's investments is set forth below.

High Yield Securities ("Junk Bonds")

As described under "The Fund's Investment Objectives and Strategies" in the Prospectus, under normal market conditions, the Fund seeks to achieve its investment objectives by investing at least 80% of its net assets (plus any borrowing for investment purposes) in debt securities that are, at the time of purchase, rated below investment grade (below Baa by Moody's Investors Service, Inc. ("Moody's"), below BBB by either Standard and Poor's ("S&P") or Fitch, Inc. ("Fitch Ratings"), or below a comparable rating by Dominion Bond Rating Service Limited ("Dominion")) or unrated but judged by Pacific Investment Management Company LLC ("PIMCO"), the Fund's portfolio manager, to be of comparable quality. These securities are sometimes referred to as "high yield" securities or "junk bonds." The Fund will not invest more than 10% of its total assets in securities that are, at the time of purchase, rated CCC/Caa (or a comparable rating by Dominion) or lower by each agency rating the security or unrated but judged by PIMCO to be of comparable quality.

Investments in high yield securities generally provide greater income and increased opportunity for capital appreciation than investments in higher quality securities, but they also typically entail greater price volatility and principal and income risk, including the possibility of issuer default and bankruptcy. High yield securities are regarded as predominantly speculative with respect to the issuer's continuing ability to meet principal and interest payments. Debt securities in the lowest investment grade category also may be considered to possess some speculative characteristics by certain rating agencies. In addition, analysis of the creditworthiness of issuers of high yield securities may be more complex than for issuers of higher quality securities.

High yield securities may be more susceptible to real or perceived adverse economic and competitive industry conditions than investment grade securities. A projection of an economic downturn or of a period of rising interest rates, for example, could cause a decline in high yield security prices because the advent of a recession could lessen the ability of an issuer to make principal and interest payments on its debt obligations. If an issuer of high yield securities defaults, in addition to risking non-payment of all or a portion of interest and principal, the Fund may incur additional expenses to seek recovery. The market prices of high yield securities

-3-

structured as zero-coupon, step-up or payment-in-kind securities will normally be affected to a greater extent by interest rate changes, and therefore tend to be more volatile than the prices of securities that pay interest currently and in cash. PIMCO seeks to reduce these risks through diversification, credit analysis and attention to current developments and trends in both the economy and financial markets.

The secondary market on which high yield securities are traded may be less liquid than the market for investment grade securities. Less liquidity in the secondary trading market could adversely affect the price at which the Fund could sell a high yield security, and could adversely affect the net asset value of the shares. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may decrease the values and liquidity of high yield securities, especially in a thinly-traded market. When secondary markets for high yield securities are less liquid than the market for investment grade securities, it may be more difficult to value the securities because such valuation may require more research, and elements of judgment may play a greater role in the valuation because there is less reliable, objective data available. During periods of thin trading in these markets, the spread between bid and asked prices is likely to increase significantly and the Fund may have greater difficulty selling its portfolio securities. The Fund will be more dependent on PIMCO's research and analysis when investing in high yield securities. PIMCO seeks to minimize the risks of investing through in-depth credit analysis and attention to current developments in interest rates and market conditions.

A general description of the ratings of securities by Moody's, S&P, Fitch Ratings and Dominion is set forth in Appendix A to the Prospectus. The ratings of Moody's, S&P, Fitch Ratings and Dominion represent their opinions as to the quality of the securities they rate. It should be emphasized, however, that ratings are general and are not absolute standards of quality. Consequently, debt obligations with the same maturity, coupon and rating may have different yields while obligations with the same maturity and coupon with different ratings may have the same yield. For these reasons, the use of credit ratings as the sole method of evaluating high yield securities can involve certain risks. For example, credit ratings evaluate the safety of principal and interest payments, not the market value risk of high yield securities. Also, credit rating agencies may fail to change credit ratings in a timely fashion to reflect events since the security was last rated. PIMCO does not rely solely on credit ratings when selecting securities for the Fund, and develops its own independent analysis of issuer credit quality.

The Fund's credit quality policies apply only at the time a security is purchased, and the Fund is not required to dispose of a security in the event that a rating agency or PIMCO downgrades its assessment of the credit characteristics of a particular issue. In determining whether to retain or sell such a security, PIMCO may consider such factors as PIMCO's assessment of the credit quality of the issuer of such security, the price at which such security could be sold and the rating, if any, assigned to such security by other rating agencies. However, analysis of creditworthiness may be more complex for issuers of high yield securities than for issuers of higher quality debt securities.

Corporate Bonds

The Fund may invest in a wide variety of bonds and related debt obligations of varying maturities issued by U.S. and foreign corporations and other business entities. Bonds are fixed

-4-

or variable rate debt obligations, including bills, notes, debentures, money market instruments and similar instruments and securities. Bonds generally are used by corporations and other issuers to borrow money from investors. The issuer pays the investor a fixed or variable rate of interest and normally must repay the amount borrowed on or before maturity. Certain bonds are "perpetual" in that they have no maturity date.

The Fund's investments in corporate bonds are subject to a number of risks described in the Prospectus and elaborated upon elsewhere in this section of the Statement of Additional Information, including interest rate risk, credit risk, high yield risk, issuer risk, foreign (non-U.S.) investment risk, inflation risk, liquidity risk, smaller company risk and management risk.

Credit Default Swaps

The Fund may enter into credit default swap contracts for hedging purposes or to add leverage to the portfolio. As the seller in a credit default swap contract, the Fund would be required to pay the par (or other agreed-upon) value of a referenced debt obligation to the counterparty in the event of a default by a third party, such as a U.S. or foreign issuer, on the debt obligation. In return, the Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default has occurred. If no default occurs, the Fund would keep the stream of payments and would have no payment obligations. As the seller, the Fund would effectively add leverage to its portfolio because, in addition to its total net assets, the Fund would be subject to investment exposure on the notional amount of the swap.

The Fund may also purchase credit default swap contracts in order to hedge against the risk of default of debt securities held in its portfolio, in which case the Fund would function as the counterparty referenced in the preceding paragraph. This would involve the risk that the investment may expire worthless and would generate income only in the event of an actual default by the issuer of the underlying obligation (as opposed to a credit downgrade or other indication of financial instability). It would also involve credit risk - that the seller may fail to satisfy its payment obligations to the Fund in the event of a default.

PIMCO currently considers credit default swaps to be illiquid and treats the market value of the contract as illiquid for purposes of determining compliance with the Fund's limitations on on illiquid investments.

Commercial Paper

Commercial paper represents short-term unsecured promissory notes issued in bearer form by corporations such as banks or bank holding companies and finance companies. The Fund may invest in commercial paper of any credit quality consistent with the Fund's investment objectives and policies, including unrated commercial paper for which PIMCO has made a credit quality assessment. See Appendix A to the Prospectus for a description of the ratings assigned by Moody's, S&P, Fitch Ratings and Dominion to commercial paper. The rate of return on commercial paper may be linked or indexed to the level of exchange rates between the U.S. dollar and a foreign currency or currencies.

Preferred Stock

Preferred stock represents an equity interest in a company that generally entitles the holder to receive, in preference to the holders of other stocks such as common stocks, dividends and a fixed share of the proceeds resulting from a liquidation of the company. Some preferred stocks also entitle their holders to receive additional liquidation proceeds on the same basis as holders of a company's common stock, and thus also represent an ownership interest in that company. As described below, the Fund may invest in preferred stocks that pay fixed or adjustable rates of return. The value of a company's preferred stock may fall as a result of factors relating directly to that company's products or services. A preferred stock's value may also fall because of factors affecting not just the company, but companies in the same industry or in a number of different industries, such as increases in production costs. The value of preferred stock may also be affected by changes in financial markets that are relatively unrelated to the company or its industry, such as changes in interest rates or currency exchange rates. In addition, a company's preferred stock generally pays dividends only after the company makes required payments to holders of its bonds and other debt. For this reason, the value of the preferred stock will usually react more strongly than bonds and other debt to actual or perceived changes in the company's financial condition or prospects. Preferred stocks of smaller companies may be more vulnerable to adverse developments than those of larger companies.

Fixed Rate Preferred Stocks. Some fixed rate preferred stocks in which the Fund may invest, known as perpetual preferred stocks, offer a fixed return with no maturity date. Because they never mature, perpetual preferred stocks act like long-term bonds, can be more volatile than other types of preferred stocks that have a maturity date and may have heightened sensitivity to changes in interest rates. The Fund may also invest in sinking fund preferred stocks. These preferred stocks also offer a fixed return, but have a maturity date and are retired or redeemed on a predetermined schedule. The shorter duration of sinking fund preferred stocks makes them perform somewhat like intermediate-term bonds and they typically have lower yields than perpetual preferred stocks.

Adjustable Rate and Auction Preferred Stocks. Typically, the dividend rate on an adjustable rate preferred stock is determined prospectively each quarter by applying an adjustment formula established at the time of issuance of the stock. Although adjustment formulas vary among issues, they typically involve a fixed premium or discount relative to rates on specified debt securities issued by the U.S. Treasury. Typically, an adjustment formula will provide for a fixed premium or discount adjustment relative to the highest base yield of three specified U.S. Treasury securities: the 90-day Treasury bill, the 10-year Treasury note and the 20-year Treasury bond. The premium or discount adjustment to be added to or subtracted from this highest U.S. Treasury base rate yield is fixed at the time of issue and cannot be changed without the approval of the holders of the stock. The dividend rate on other preferred stocks in which the Fund may invest, commonly known as auction preferred stocks, is adjusted at intervals that may be more frequent than quarterly, such as every 49 days, based on bids submitted by holders and prospective purchasers of such stocks and may be subject to stated maximum and minimum dividend rates. The issues of most adjustable rate and auction preferred stocks currently outstanding are perpetual, but are redeemable after a specified date at the option of the issuer. Certain issues supported by the credit of a high-rated financial institution provide for mandatory redemption prior to expiration of the credit arrangement. No redemption can occur if

-6-

full cumulative dividends are not paid. Although the dividend rates on adjustable and auction preferred stocks are generally adjusted or reset frequently, the market values of these preferred stocks may still fluctuate in response to changes in interest rates. Market values of adjustable preferred stocks also may substantially fluctuate if interest rates increase or decrease once the maximum or minimum dividend rate for a particular stock is approached.

Convertible Securities and Synthetic Convertible Securities

The Fund may invest in convertible securities, which are bonds, debentures, notes or other securities that entitle the holder to acquire common stock or other equity securities of the same or a different issuer. Convertible securities have general characteristics similar to both debt and equity securities. PIMCO will generally evaluate these instruments based on their debt characteristics.

A convertible security generally entitles the holder to receive interest paid or accrued until the convertible security matures or is redeemed, converted or exchanged. Before conversion, convertible securities have characteristics similar to non-convertible debt obligations. Convertible securities rank senior to common stock in a corporation's capital structure and, therefore, generally entail less risk than the corporation's common stock, although the extent to which such risk is reduced depends in large measure upon the degree to which the convertible security sells above its value as a debt obligation.

Because of the conversion feature, the price of the convertible security will normally fluctuate in some proportion to changes in the price of the underlying asset, and will therefore be subject to risks relating to the activities of the issuer and/or general market and economic conditions. The income component of convertible securities may tend to cushion the securities against declines in the price of the underlying asset. However, the income component of convertible securities will typically cause fluctuations based upon changes in interest rates and the credit quality of the issuer. In addition, convertible securities are often lower-rated securities. See "--High Yield Securities ("Junk Bonds") above.

A convertible security may be subject to redemption at the option of the issuer at a predetermined price. If a convertible security held by the Fund is called for redemption, the Fund would be required to permit the issuer to redeem the security and convert it to underlying common stock, or would sell the convertible security to a third party, which may have an adverse effect on the Fund's ability to achieve its investment objectives.

The Fund may invest in so-called "synthetic convertible securities," which are composed of two or more different securities whose investment characteristics, taken together, resemble those of convertible securities. For example, the Fund may purchase a non-convertible debt security and a warrant or option. The synthetic convertible security differs from the true convertible security in several respects. Unlike a true convertible security, which is a single security having a unitary market value, a synthetic convertible security comprises two or more separate securities, each with its own market value. Therefore, the "market value" of a synthetic convertible security is the sum of the values of its debt component and its convertible component. For this reason, the values of a synthetic convertible security and a true convertible security may respond differently to market fluctuations.

Bank Obligations

Bank obligations in which the Fund may invest include certificates of deposit, bankers' acceptances, and fixed time deposits. Certificates of deposit are negotiable certificates that are issued against funds deposited in a commercial bank for a definite period of time and that earn a specified return. Bankers' acceptances are negotiable drafts or bills of exchange, normally drawn by an importer or exporter to pay for specific merchandise, which are "accepted" by a bank, meaning, in effect, that the bank unconditionally agrees to pay the face value of the instrument on maturity. Fixed time deposits are bank obligations payable at a stated maturity date and bearing interest at a fixed rate. Fixed time deposits may be withdrawn on demand by the investor, but may be subject to early withdrawal penalties which vary depending upon market conditions and the remaining maturity of the obligation. There are generally no contractual restrictions on the right to transfer a beneficial interest in a fixed time deposit to a third party, although there is no market for such deposits. The Fund may also hold funds on deposit with its custodian bank in an interest-bearing account for temporary purposes.

Subject to the Fund's limitation on concentration of no more than 25% of its total assets in the securities of issuers in a particular industry, the Fund may invest without limit in U.S. dollar-denominated obligations of foreign banks and up to 15% of its total assets in foreign bank obligations denominated in foreign currencies (of both developed and "emerging market" countries). Obligations of foreign banks involve certain risks associated with investing in foreign securities described under "--Foreign (Non-U.S.) Securities" below, including the possibilities that their liquidity could be impaired because of future political and economic developments, that their obligations may be less marketable than comparable obligations of U.S. banks, that a foreign jurisdiction might impose withholding taxes on interest income payable on those obligations, that foreign deposits may be seized or nationalized, that foreign governmental restrictions such as exchange controls may be adopted which might adversely affect the payment of principal and interest on those obligations and that the selection of those obligations may be more difficult because there may be less publicly available information concerning foreign banks or the accounting, auditing and financial reporting standards, practices and requirements applicable to foreign banks may differ from those applicable to U.S. banks. Foreign banks are not generally subject to examination by any U.S. Government agency or instrumentality.

Loan Participations and Assignments

The Fund may purchase participations in commercial loans. Such indebtedness may be secured or unsecured. Loan participations typically represent direct participations in a loan to a corporate borrower, and generally are offered by banks or other financial institutions or lending syndicates. The Fund may participate in such syndications, or can buy part of a loan, becoming a part lender. When purchasing loan participations, the Fund assumes the credit risk associated with the corporate borrower and may assume the credit risk associated with an interposed bank or other financial intermediary. The participation interests in which the Fund intends to invest may not be rated by any nationally recognized rating service. Given the current structure of the markets for loan participations and assignments, the Fund expects to treat these securities as illiquid. Bank loans purchased by the Fund will typically be part of an issue of at least $250 million in par value, which PIMCO believes are generally more liquid than bank loans that are part of smaller issues.

-8-

A loan is often administered by an agent bank acting as agent for all holders. The agent bank administers the terms of the loan, as specified in the loan agreement. In addition, the agent bank is normally responsible for the collection of principal and interest payments from the corporate borrower and the apportionment of these payments to the credit of all institutions which are parties to the loan agreement. Unless, under the terms of the loan or other indebtedness, the Fund has direct recourse against the corporate borrower, the Fund may have to rely on the agent bank or other financial intermediary to apply appropriate credit remedies against a corporate borrower.

A financial institution's employment as agent bank might be terminated in the event that it fails to observe a requisite standard of care or becomes insolvent. A successor agent bank would generally be appointed to replace the terminated agent bank, and assets held by the agent bank under the loan agreement should remain available to holders of such indebtedness. However, if assets held by the agent bank for the benefit of the Fund were determined to be subject to the claims of the agent bank's general creditors, the Fund might incur certain costs and delays in realizing payment on a loan or loan participation and could suffer a loss of principal and/or interest. In situations involving other interposed financial institutions (e.g., an insurance company or government agency) similar risks may arise.

Purchasers of loans and other forms of direct indebtedness depend primarily upon the creditworthiness of the corporate borrower for payment of principal and interest. If the Fund does not receive scheduled interest or principal payments on such indebtedness, the Fund's share price and yield could be adversely affected. 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.

The Fund may invest in loan participations with credit quality comparable to that of issuers of its securities investments. Indebtedness of companies whose creditworthiness is poor involves substantially greater risks, and may be highly speculative. Some companies may never pay off their indebtedness, or may pay only a small fraction of the amount owed. Consequently, when investing in indebtedness of companies with poor credit, the Fund bears a substantial risk of losing the entire amount invested.

The Fund limits the amount of its total assets that it will invest in any one issuer or in issuers within the same industry (see "Investment Restrictions"). For purposes of these limits, the Fund generally will treat the corporate borrower as the "issuer" of indebtedness held by the Fund. In the case of loan participations where a bank or other lending institution serves as a financial intermediary between the Fund and the corporate borrower, if the participation does not shift to the Fund the direct debtor-creditor relationship with the corporate borrower, SEC interpretations require the Fund to treat both the lending bank or other lending institution and the corporate borrower as "issuers" for the purposes of determining whether the Fund has invested more than 5% of its total assets in a single issuer. Treating a financial intermediary as an issuer of indebtedness may restrict the Fund's ability to invest in indebtedness related to a single financial intermediary, or a group of intermediaries engaged in the same industry, even if the underlying borrowers represent many different companies and industries.

Loans and other types of direct indebtedness may not be readily marketable and may be subject to restrictions on resale. In some cases, negotiations involved in disposing of indebtedness may require weeks to complete. Consequently, some indebtedness may be difficult or impossible to dispose of readily at what PIMCO believes to be a fair price. In addition, valuation of illiquid indebtedness involves a greater degree of judgment in determining the Fund's net asset value than if that value were based on available market quotations, and could result in significant variations in the Fund's daily share price. At the same time, some loan interests are traded among certain financial institutions and accordingly may be deemed liquid. As the market for different types of indebtedness develops, the liquidity of these instruments is expected to improve. In addition, the Fund currently intends to treat indebtedness for which there is no readily available market as illiquid for purposes of the Fund's limitation on illiquid investments. Investments in loan participations are considered to be debt obligations for purposes of the Fund's investment restriction relating to the lending of funds or assets.

Investments in loans through a direct assignment of the financial institution's interests with respect to the loan may involve additional risks to the Fund. For example, if a loan is foreclosed, the Fund could become part owner of any collateral, and would bear the costs and liabilities associated with owning and disposing of the collateral. In addition, it is conceivable that, under emerging legal theories of lender liability, the Fund could be held liable as co-lender. It is unclear whether loans and other forms of direct indebtedness offer securities law protections against fraud and misrepresentation. In the absence of definitive regulatory guidance, the Fund relies on PIMCO's research in an attempt to avoid situations where fraud or misrepresentations could adversely affect the Fund.

Zero-Coupon Bonds, Step-Ups and Payment-In-Kind Securities

Zero-coupon securities are debt obligations that do not entitle the holder to any periodic payments of interest either for the entire life of the obligation or for an initial period after the issuance of the obligations. Like zero-coupon bonds, "step-up" bonds pay no interest initially but eventually begin to pay a coupon rate prior to maturity, which rate may increase at stated intervals during the life of the security. Payment-in-kind securities (PIKs) pay dividends or interest in the form of additional securities of the issuer, rather than in cash. Each of these instruments is typically issued and traded at a deep discount from its face amount. The amount of the discount varies depending on such factors as the time remaining until maturity of the securities, prevailing interest rates, the liquidity of the security and the perceived credit quality of the issuer. The market prices of zero-coupon bonds, step-ups and PIKs generally are more volatile than the market prices of debt instruments that pay interest currently and in cash and are likely to respond to changes in interest rates to a greater degree than do other types of securities having similar maturities and credit quality. In order to satisfy a requirement for qualification as a "regulated investment company" under the Internal Revenue Code of 1986, as amended (the "Code"), an investment company, such as the Fund, must distribute each year at least 90% of its net investment income, including the original issue discount accrued on zero-coupon bonds, step-ups and PIKs. Because the Fund will not, on a current basis, receive cash payments from the issuer of these securities in respect of any accrued original issue discount, in some years the Fund may have to distribute cash obtained from selling other portfolio holdings of the Fund. In some circumstances, such sales might be necessary in order to satisfy cash distribution requirements even though investment considerations might otherwise make it undesirable for the

-10-

Fund to sell securities at such time. Under many market conditions, investments in zero-coupon bonds, step-ups and PIKs may be illiquid, making it difficult for the Fund to dispose of them or determine their current value.

Foreign (Non-U.S.) Securities

The Fund may invest some or all of its total assets in U.S. dollar-denominated debt obligations of foreign issuers, including foreign issuers, such as foreign banks (see "--Bank Obligations" above), and obligations of foreign governments or their subdivisions, agencies and instrumentalities, international agencies and supra-national government entities. The Fund may also invest up to 15% of its total assets in debt instruments denominated in foreign currencies (of both developed and "emerging market" countries), including obligations of non-U.S. governments and their respective sub-divisions, agencies and government-sponsored enterprises. The Fund may invest without limit in U.S. dollar-denominated securities of issues located in developed countries, and may invest up to 7.5% of its total assets in securities (regardless of the currency in which such investments are denominated) of issues located in "emerging market" countries.

The U.S. dollar-denominated foreign securities in which the Fund may invest include Eurodollar obligations and "Yankee Dollar" obligations. Eurodollar obligations are U.S. dollar-denominated certificates of deposit and time deposits issued outside the U.S. capital markets by foreign branches of U.S. banks and by foreign banks. Yankee Dollar obligations are U.S. dollar-denominated obligations issued in the U.S. capital markets by foreign banks. Eurodollar and Yankee Dollar obligations are generally subject to the same risks that apply to domestic debt issues, notably credit risk, market risk and liquidity risk. Additionally, Eurodollar (and to a limited extent, Yankee Dollar) obligations are subject to certain sovereign risks. One such risk is the possibility that a sovereign country might prevent capital, in the form of U.S. dollars, from flowing across its borders. Other risks include adverse political and economic developments; the extent and quality of government regulation of financial markets and institutions; the imposition of foreign withholding taxes; and the expropriation or nationalization of foreign issuers.

The Fund may also invest in American Depository Receipts ("ADRs"), European Depository Receipts ("EDRs") or Global Depository Receipts ("GDRs"). ADRs are U.S. dollar-denominated receipts issued generally by domestic banks and represent the deposit with the bank of a security of a foreign issuer. EDRs are foreign currency-denominated receipts similar to ADRs and are issued and traded in Europe, and are publicly traded on exchanges or over-the-counter in the United States. GDRs may be offered privately in the United States and also trade in public or private markets in other countries. ADRs, EDRs and GDRs may be issued as sponsored or unsponsored programs. In sponsored programs, an issuer has made arrangements to have its securities trade in the form of ADRs, EDRs or GDRs. In unsponsored programs, the issuer may not be directly involved in the creation of the program. Although regulatory requirements with respect to sponsored and unsponsored programs are generally similar, in some cases it may be easier to obtain financial information from an issuer that has participated in the creation of a sponsored program.

The Fund also may invest in Brady Bonds. Brady Bonds are securities created through the exchange of existing commercial bank loans to sovereign entities for new obligations in

-11-

connection with debt restructurings under a debt restructuring plan introduced by former U.S. Secretary of the Treasury, Nicholas F. Brady (the "Brady Plan"). Brady Plan debt restructurings have been implemented in a number of countries, including: Argentina, Bolivia, Brazil, Bulgaria, Costa Rica, the Dominican Republic, Ecuador, Jordan, Mexico, Niger, Nigeria, Panama, Peru, the Philippines, Poland, Uruguay, and Venezuela.

Brady Bonds may be collateralized or uncollateralized, are issued in various currencies (primarily the U.S. dollar) and are actively traded in the over-the-counter secondary market. Brady Bonds are not considered to be U.S. Government securities. U.S. dollar-denominated, collateralized Brady Bonds, which may be fixed rate par bonds or floating rate discount bonds, are generally collateralized in full as to principal by U.S. Treasury zero-coupon bonds having the same maturity as the Brady Bonds. Interest payments on these Brady Bonds generally are collateralized on a one-year or longer rolling-forward basis by cash or securities in an amount that, in the case of fixed rate bonds, is equal to at least one year of interest payments or, in the case of floating rate bonds, initially is equal to at least one year's interest payments based on the applicable interest rate at that time and is adjusted at regular intervals thereafter. Certain Brady Bonds are entitled to "value recovery payments" in certain circumstances, which in effect constitute supplemental interest payments but generally are not collateralized. Brady Bonds are often viewed as having three or four valuation components: (i) the collateralized repayment of principal at final maturity; (ii) the collateralized interest payments; (iii) the uncollateralized interest payments; and (iv) any uncollateralized repayment of principal at maturity (the uncollateralized amounts constitute the "residual risk").

Most Mexican Brady Bonds issued to date have principal repayments at final maturity fully collateralized by U.S. Treasury zero-coupon bonds (or comparable collateral denominated in other currencies) and interest coupon payments collateralized on an 18-month rolling-forward basis by funds held in escrow by an agent for the bondholders. A significant portion of the Venezuelan Brady Bonds and the Argentine Brady Bonds issued to date have repayments at final maturity collateralized by U.S. Treasury zero-coupon bonds (or comparable collateral denominated in other currencies) and/or interest coupon payments collateralized on a 14-month (for Venezuela) or 12-month (for Argentina) rolling-forward basis by securities held by the Federal Reserve Bank of New York as collateral agent.

Brady Bonds involve various risk factors including residual risk and the history of defaults with respect to commercial bank loans by public and private entities of countries issuing Brady Bonds. There can be no assurance that Brady Bonds in which the Fund may invest will not be subject to restructuring arrangements or to requests for new credit, which may cause the Fund to suffer a loss of interest or principal on any of its holdings.

Investing in the securities of foreign issuers involves special risks and considerations not typically associated with investing in U.S. companies. These include: differences in accounting; auditing and financial reporting standards; generally higher commission rates on foreign portfolio transactions; the possibility of expropriation or confiscatory taxation; adverse changes in investment or exchange control regulations (which may include suspension of the ability to transfer currency from a country); political instability which can affect U.S. investments in foreign countries and potential restrictions on the flow of international capital. In addition, foreign securities and dividends and interest payable on those securities may be subject to

-12-

foreign taxes, including taxes withheld from payments on those securities. Foreign securities often trade with less frequency and volume than domestic securities and therefore may exhibit greater price volatility. Changes in foreign exchange rates will affect the value of those securities which are denominated or quoted in currencies other than the U.S. dollar.

Emerging Market Securities. The risks of investing in foreign securities are particularly high when securities of issuers based in or denominated in currencies of developing (or "emerging market") countries are involved. Investing in emerging market countries involves certain risks not typically associated with investing in U.S. securities, and imposes risks greater than, or in addition to, risks of investing in foreign, developed countries. These risks include: greater risks of nationalization or expropriation of assets or confiscatory taxation; currency devaluations and other currency exchange rate fluctuations; greater social, economic and political uncertainty and instability (including the risk of war); more substantial government involvement in the economy; less government supervision and regulation of the securities markets and participants in those markets; controls on foreign investment and limitations on repatriation of invested capital and on the Fund's ability to exchange local currencies for U.S. dollars; unavailability of currency hedging techniques in certain emerging market countries; the fact that companies in emerging market countries may be smaller, less seasoned and newly organized; the difference in, or lack of, auditing and financial reporting standards, which may result in unavailability of material information about issuers; the risk that it may be more difficult to obtain and/or enforce a judgment in a court outside the United States; and greater price volatility, substantially less liquidity and significantly smaller market capitalization of securities markets. In addition, a number of emerging market countries restrict, to various degrees, foreign investment in securities, and high rates of inflation and rapid fluctuations in inflation rates have had, and may continue to have, negative effects on the economies and securities markets of certain emerging market countries. Also, any change in the leadership or politics of emerging market countries, or the countries that exercise a significant influence over those countries, may halt the expansion of or reverse the liberalization of foreign investment policies now occurring and adversely affect existing investment opportunities.

Sovereign Debt. Investment in sovereign debt can involve a high degree of risk. The governmental entity that controls the repayment of sovereign debt may not be able or willing to repay the principal and/or interest when due in accordance with the terms of the debt. A governmental entity's willingness or ability to repay principal and interest due in a timely manner may be affected by, among other factors, its cash flow situation, the extent of its foreign reserves, the availability of sufficient foreign exchange on the date a payment is due, the relative size of the debt service burden to the economy as a whole, the governmental entity's policy toward the International Monetary Fund, and the political constraints to which a governmental entity may be subject. Governmental entities may also depend on expected disbursements from foreign governments, multilateral agencies and others to reduce principal and interest arrearages on their debt. The commitment on the part of these governments, agencies and others to make such disbursements may be conditioned on a governmental entity's implementation of economic reforms and/or economic performance and the timely service of such debtor's obligations. Failure to implement such reforms, achieve such levels of economic performance or repay principal or interest when due may result in the cancellation of such third parties' commitments to lend funds to the governmental entity, which may further impair such debtor's ability or willingness to service its debts in a timely manner. Consequently, governmental entities may

-13-

default on their sovereign debt. Holders of sovereign debt (including the Fund) may be requested to participate in the rescheduling of such debt and to extend further loans to governmental entities. There is no bankruptcy proceeding by which sovereign debt on which governmental entities have defaulted may be collected in whole or in part.

The Fund's investments in foreign currency-denominated debt obligations and hedging activities will likely produce a difference between its book income and its taxable income. This difference may cause a portion of the Fund's income distributions to constitute returns of capital for tax purposes or require the Fund to make distributions exceeding book income to qualify as a regulated investment company for federal income tax purposes.

Foreign Currency Transactions

The Fund also may purchase and sell foreign currency options and foreign currency futures contracts and related options (see "--Derivative Instruments" below), and may engage in foreign currency transactions either on a spot (cash) basis at the rate prevailing in the currency exchange market at the time or through forward foreign currency exchange contracts ("forwards") with terms generally of less than one year. The Fund may engage in these transactions in order to protect against uncertainty in the level of future foreign exchange rates in the purchase and sale of securities. The Fund may also use foreign currency options and foreign currency forward contracts to increase exposure to a foreign currency or to shift exposure to foreign currency fluctuations from one country to another. The Fund normally will seek to hedge at least 75% of its exposure to foreign currencies in order to reduce the risk of loss due to fluctuations in currency exchange rates. Suitable currency hedging transactions may not be available in all circumstances and PIMCO may decide not to use hedging transactions that are available.

A forward involves an obligation to purchase or sell a specific currency at a future date, which may be any fixed number of days from the date of the contract agreed upon by the parties, at a price set at the time of the contract. These contracts may be bought or sold to protect the Fund against a possible loss resulting from an adverse change in the relationship between foreign currencies and the U.S. dollar or to increase exposure to a particular foreign currency. Open positions in forwards used for non-hedging purposes will be covered by the segregation with the Fund's custodian of assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, and are marked to market daily. Although forwards are intended to minimize the risk of loss due to a decline in the value of the hedged currencies, at the same time, they tend to limit any potential gain which might result should the value of such currencies increase. Forwards will be used primarily to adjust the foreign exchange exposure of the Fund with a view to protecting the outlook, and the Fund might be expected to enter into such contracts under the following circumstances:

Lock In. When PIMCO desires to lock in the U.S. dollar price on the purchase or sale of a security denominated in a foreign currency.

Cross Hedge. If a particular currency is expected to decrease against another currency, the Fund may sell the currency expected to decrease and purchase a currency that is expected to

-14-

increase against the currency sold in an amount approximately equal to some or all of the Fund's portfolio holdings denominated in the currency sold.

Direct Hedge. If PIMCO wants to eliminate substantially all of the risk of owning a particular currency, and/or if PIMCO believes that the Fund can benefit from price appreciation in a given country's debt obligations but does not want to hold the currency, it may employ a direct hedge back into the U.S. dollar. In either case, the Fund would enter into a forward contract to sell the currency in which a portfolio security is denominated and purchase U.S. dollars at an exchange rate established at the time it initiated a contract. The cost of the direct hedge transaction may offset most, if not all, of the yield advantage offered by the foreign security, but the Fund would hope to benefit from an increase (if any) in the value of the debt obligation.

Proxy Hedge. PIMCO might choose to use a proxy hedge, which may be less costly than a direct hedge. In this case, the Fund, having purchased a security, will sell a currency whose value is believed to be closely linked to the currency in which the security is denominated. Interest rates prevailing in the country whose currency was sold would be expected to be close to those in the United States and lower than those of securities denominated in the currency of the original holding. This type of hedging entails greater risk than a direct hedge because it is dependent on a stable relationship between the two currencies paired as proxies and the relationships can be very unstable at times.

Costs of Hedging. When the Fund purchases a foreign bond with a higher interest rate than is available on U.S. bonds of a similar maturity, the additional yield on the foreign bond could be substantially reduced or lost if the Fund were to enter into a direct hedge by selling the foreign currency and purchasing the U.S. dollar. This is what is known as the "cost" of hedging. Proxy hedging attempts to reduce this cost through an indirect hedge back to the U.S. dollar.

It is important to note that hedging costs are treated as capital transactions and are not, therefore, deducted from the Fund's dividend distribution and are not reflected in its yield.

Tax Consequences of Hedging. Under applicable tax law, the Fund's hedging activities may result in the application of the mark-to-market and straddle provisions of the Code. Those provisions could result in an increase (or decrease) in the amount of taxable dividends paid by the Fund and could affect whether dividends paid by the Fund are classified as capital gains or ordinary income.

Foreign Currency Exchange-Related Securities

Foreign Currency Warrants. Foreign currency warrants, such as Currency Exchange Warrants(SM) ("CEWs(SM)"), are warrants that entitle their holders to receive from their issuer an amount of cash (generally, for warrants issued in the United States, in U.S. dollars) that is calculated pursuant to a predetermined formula and based on the exchange rate between a specified foreign currency and the U.S. dollar as of the exercise date of the warrant. Foreign currency warrants generally are exercisable upon their issuance and expire as of a specific date and time. Foreign currency warrants have been issued in connection with U.S. dollar-denominated debt offerings by major issuers in an attempt to reduce the foreign currency

-15-

exchange risk that, from the point of view of the prospective purchasers of the securities, is inherent in the international debt obligation marketplace. Foreign currency warrants may attempt to reduce the foreign exchange risk assumed by purchasers of a security by, for example, providing for a supplement payment in the event that the U.S. dollar depreciates against the value of a major foreign currency such as the Japanese yen. The formula used to determine the amount payable upon exercise of a foreign currency warrant may make the warrant worthless unless the applicable foreign currency exchange rate moves in a particular direction (e.g., unless the U.S. dollar appreciates or depreciates against the particular foreign currency to which the warrant is linked or indexed). Foreign currency warrants are severable from the debt obligations with which they may be offered, and may be listed on exchanges. Foreign currency warrants may be exercisable only in certain minimum amounts, and an investor wishing to exercise warrants who possesses less than the minimum number required for exercise may be required either to sell the warrants or to purchase additional warrants, thereby incurring additional transaction costs. In the case of any exercise of warrants, there may be a time delay between the time a holder of warrants gives instructions to exercise and the time the exchange rate relating to exercise is determined, during which time the exchange rate could change significantly, thereby affecting both the market and cash settlement values of the warrants being exercised. The expiration date of the warrants may be accelerated if the warrants should be delisted from an exchange or if their trading should be suspended permanently, which would result in the loss of any remaining "time values" of the warrants (i.e., the difference between the current market value and the exercise value of the warrants), and, if the warrants were "out-of-the-money," in a total loss of the purchase price of the warrants. Warrants are generally unsecured obligations of their issuers and are not standardized foreign currency options issued by the Options Clearing Corporation ("OCC"). Unlike foreign currency options issued by the OCC, the terms of foreign exchange warrants generally will not be amended in the event of government or regulatory actions affecting exchange rates or in the event of the imposition of other regulatory controls affecting the international currency markets. The initial public offering price of foreign currency warrants is generally considerably in excess of the price that a commercial user of foreign currencies might pay in the interbank market for a comparable option involving significantly larger amounts of foreign currencies. Foreign currency warrants are subject to significant foreign exchange risk, including risks arising from complex political or economic factors.

Principal Exchange Rate Linked Securities. Principal exchange rate linked securities ("PERLs(SM)") are debt obligations the principal on which is payable at maturity in an amount that may vary based on the exchange rate between the U.S. dollar and a particular foreign currency at or about that time. The return on "standard" principal exchange rate linked securities is enhanced if the foreign currency to which the security is linked appreciates against the U.S. dollar, and is adversely affected by increases in the foreign exchange value of the U.S. dollar; "reverse" principal exchange rate linked securities are like "standard" securities, except that their return is enhanced by increases in the value of the U.S. dollar and adversely impacted by increases in the value of foreign currency. Interest payments on the securities are generally made in U.S. dollars at rates that reflect the degree of foreign currency risk assumed or given up by the purchaser of the notes (i.e., at relatively higher interest rates if the purchaser has assumed some of the foreign exchange risk, or relatively lower interest rates if the issuer has assumed some of the foreign exchange risk, based on the expectations of the current market). Principal exchange rate linked securities may in limited cases be subject to acceleration of maturity (generally, not

-16-

without the consent of the holders of the securities), which may have an adverse impact on the value of the principal payment to be made at maturity.

Performance Indexed Paper. Performance indexed paper ("PIPs(SM)") is U.S. dollar-denominated commercial paper the yield of which is linked to certain foreign exchange rate movements. The yield to the investor on performance indexed paper is established at maturity as a function of spot exchange rates between the U.S. dollar and a designated currency as of or about that time (generally, the index maturity two days prior to maturity). The yield to the investor will be within a range stipulated at the time of purchase of the obligation, generally with a guaranteed minimum rate of return that is below, and a potential maximum rate of return that is above, market yields on U.S. dollar-denominated commercial paper, with both the minimum and maximum rates of return on the investment corresponding to the minimum and maximum values of the spot exchange rate two business days prior to maturity.

Derivative Instruments

In pursuing its investment objectives, the Fund may purchase and sell
(write) both put options and call options on securities, swap agreements, and securities indexes, and enter into interest rate and index futures contracts and purchase and sell options on such futures contracts ("futures options") for hedging or risk management purposes or as part of its overall investment strategy. The Fund also may enter into swap agreements with respect to interest rates, currencies, securities indexes and other assets and measures of risk or return. If other types of financial instruments, including other types of options, futures contracts or futures options are traded in the future, the Fund may also use those instruments, provided that the Trustees determine that their use is consistent with the Fund's investment objectives. The Fund may invest in derivatives without limit for hedging purposes, and may invest up to 25% (10% within 90 days of the date of the Prospectus) of its total assets in derivatives for non-hedging purposes. For these purposes, "hedging purposes" shall include the use of a derivative instrument to cause the Fund to more closely resemble the Merrill Lynch U.S. High Yield BB-B Rated Index with respect to credit quality, average portfolio duration, and/or average portfolio yield-to-maturity.

The value of some derivative instruments in which the Fund may invest may be particularly sensitive to changes in prevailing interest rates, and, like the other investments of the Fund, the ability of the Fund to successfully utilize these instruments may depend in part upon the ability of PIMCO to forecast interest rates and other economic factors correctly. If PIMCO incorrectly forecasts such factors and has taken positions in derivative instruments contrary to prevailing market trends, the Fund could be exposed to the risk of loss.

The Fund might not employ any of the strategies described below, and no assurance can be given that any strategy used will succeed. If PIMCO incorrectly forecasts interest rates, market values or other economic factors in utilizing a derivatives strategy for the Fund, the Fund might have been in a better position if it had not entered into the transaction at all. Also, suitable derivative transactions may not be available in all circumstances. The use of these strategies involves certain special risks, including a possible imperfect correlation, or even no correlation, between price movements of derivative instruments and price movements of related investments. While some strategies involving derivative instruments can reduce the risk of loss, they can also reduce the opportunity for gain or even result in losses by offsetting favorable price movements

-17-

in related investments or otherwise, due to the possible inability of the Fund to purchase or sell a portfolio security at a time that otherwise would be favorable or the possible need to sell a portfolio security at a disadvantageous time because the Fund is required to maintain asset coverage or offsetting positions in connection with transactions in derivative instruments, and the possible inability of the Fund to close out or to liquidate its derivatives positions. Income earned by the Fund from many derivative strategies will be treated as capital gain and, if not offset by net realized capital loss, will be distributed to shareholders in taxable distributions.

Options on Securities, Swap Agreements and Indexes. The Fund may purchase and sell both put and call options on securities, swap agreements or indexes in standardized contracts traded on domestic or other securities exchanges, boards of trade, or similar entities, or quoted on NASDAQ or on an over-the-counter market, and agreements, sometimes called cash puts, which may accompany the purchase of a new issue of debt obligations from a dealer.

An option on a security (or an index) is a contract that gives the holder of the option, in return for a premium, the right to buy from (in the case of a call) or sell to (in the case of a put) the writer of the option the security underlying the option (or the cash value of the index) at a specified exercise price at any time during the term of the option. The writer of an option on a security has the obligation upon exercise of the option to deliver the underlying security upon payment of the exercise price or to pay the exercise price upon delivery of the underlying security. Upon exercise, the writer of an option on an index is obligated to pay the difference between the cash value of the index and the exercise price multiplied by the specified multiplier for the index option. (An index is designed to reflect features of a particular securities market, a specific group of financial instruments or securities, or certain economic indicators.)

The Fund will write call options and put options only if they are "covered." In the case of a call option on a debt obligation or other security, the option is "covered" if the Fund owns the security underlying the call or has an absolute and immediate right to acquire that security without additional cash consideration (or, if additional cash consideration is required, cash or other assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, in such amount are segregated by its custodian) upon conversion or exchange of other securities held by the Fund. For a call option on an index, the option is covered if the Fund maintains with its custodian assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, in an amount equal to the contract value of the index. A call option is also covered if the Fund holds a call on the same security or index as the call written where the exercise price of the call held is (i) equal to or less than the exercise price of the call written, or (ii) greater than the exercise price of the call written, provided the difference is maintained by the Fund in segregated assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees. A put option on a security or an index is "covered" if the Fund segregates assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees equal to the exercise price. A put option is also covered if the Fund holds a put on the same security or index as the put written where the exercise price of the put held is (i) equal to or greater than the exercise price of the put written, or (ii) less than the exercise price of the put written, provided the difference is maintained by the Fund in segregated assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees.

-18-

If an option written by the Fund expires unexercised, the Fund realizes on the expiration date a capital gain equal to the premium the Fund received at the time the option was written. If an option purchased by the Fund expires unexercised, the Fund realizes a capital loss equal to the premium paid. Prior to the earlier of exercise or expiration, an exchange-traded option may be closed out by an offsetting purchase or sale of an option of the same series (type, exchange, underlying security or index, exercise price, and expiration). There can be no assurance, however, that a closing purchase or sale transaction can be effected when the Fund desires.

The Fund may sell put or call options it has previously purchased, which could result in a net gain or loss depending on whether the amount realized on the sale is more or less than the premium and other transaction costs paid on the put or call option which is sold. Prior to exercise or expiration, an option may be closed out by an offsetting purchase or sale of an option of the same series. 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.

The premium paid for a put or call option purchased by the Fund is an asset of the Fund. 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.

The Fund may write covered straddles consisting of a combination of a call and a put written on the same underlying security. A straddle will be covered when sufficient assets are deposited to meet the Fund's immediate obligations. The Fund may use the same liquid assets to cover both the call and put options where the exercise price of the call and put are the same, or the exercise price of the call is higher than that of the put. In such cases, the Fund will also segregate liquid assets equivalent to the amount, if any, by which the put is "in the money."

Risks Associated with Options on Securities and Indexes. There are several risks associated with transactions in options on securities and on indexes. For example, there are significant differences between the securities and options markets that could result in an imperfect correlation between 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.

During the option period, the covered call writer has, in return for the premium on the option, given up the opportunity to profit from a price increase in the underlying security above the exercise price, but, as long as its obligation as a writer continues, has retained the risk of loss should the price of the underlying security decline. The writer of an option has no control over the time when it may be required to fulfill its obligation as a writer of the option. Once an option

-19-

writer has received an exercise notice, it cannot effect a closing purchase transaction in order to terminate its obligation under the option and must deliver the underlying security at the exercise price. If a put or call option purchased by the Fund is not sold when it has remaining value, and if the market price of the underlying security remains equal to or greater than the exercise price (in the case of a put), or remains less than or equal to the exercise price (in the case of a call), the Fund will lose its entire investment in the option. Also, where a put or call option on a particular security is purchased to hedge against price movements in a related security, the price of the put or call option may move more or less than the price of the related security.

There can be no assurance that a liquid market will exist when the Fund seeks to close out an option position. If the Fund were unable to close out an option that it had purchased on a security, it would have to exercise the option in order to realize any profit or the option may expire 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 unless the option expired without exercise. As the writer of a covered call option, the Fund forgoes, 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.

If trading were suspended in an option purchased by the Fund, the Fund would not be able to close out the option. If restrictions on exercise were imposed, the Fund might be unable to exercise an option it has purchased. Except to the extent that a call option on an index written by the Fund is covered by an option on the same index purchased by the Fund, movements in the index may result in a loss to the Fund; however, such losses may be mitigated by changes in the value of the Fund's securities during the period the option was outstanding.

Foreign Currency Options. The Fund may buy or sell put and call options on foreign currencies for investment purposes or as a hedge against changes in the value of the U.S. dollar (or another currency) in relation to a foreign currency in which the Fund's securities may be denominated. The Fund may buy or sell put and call options on foreign currencies either on exchanges or in the over-the-counter market. A put option on a foreign currency gives the purchaser of the option the right to sell a foreign currency at the exercise price until the option expires. A call option on a foreign currency gives the purchaser of the option the right to purchase the currency at the exercise price until the option expires. Currency options traded on U.S. or other exchanges may be subject to position limits which may limit the ability of the Fund to reduce foreign currency risk using such options.

Futures Contracts and Options on Futures Contracts. The Fund may invest in interest rate futures contracts and options thereon ("futures options"). The Fund may also purchase and sell futures contracts on debt obligations (to the extent they are available) and U.S. Government and agency securities, as well as purchase put and call options on such futures contracts.

A futures contract provides for the future sale by one party and purchase by another party of a specified quantity of the security or other financial instrument at a specified price and time. 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 an index might be a function of the value of certain

-20-

specified securities, physical delivery of these securities is not always made. A public market exists in futures contracts covering a number of indexes as well as financial instruments, including, without limitation: U.S. Treasury bonds; U.S. Treasury notes; GNMA Certificates; three-month U.S. Treasury bills; 90-day commercial paper; bank certificates of deposit; Eurodollar certificates of deposit; the Australian dollar; the Canadian dollar; the British pound; the Japanese yen; the Swiss franc; the Mexican peso; and certain multinational currencies, such as the euro. It is expected that other futures contracts will be developed and traded in the future.

The Fund may purchase and write call and put futures options. Futures options possess many of the same characteristics as options on securities and indexes (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.

To comply with applicable rules of the Commodity Futures Trading Commission under which the Fund avoids being deemed a "commodity pool" or a "commodity pool operator," the Fund intends generally to limit its use of futures contracts and futures options to "bona fide hedging" transactions, as such term is defined in applicable regulations, interpretations and practice. For example, the Fund might use futures contracts to hedge against anticipated changes in interest rates that might adversely affect either the value of the Fund's debt obligations or the price of the debt obligations that the Fund intends to purchase. The Fund's hedging activities may include sales of futures contracts as an offset against the effect of expected increases in interest rates, and purchases of futures contracts as an offset against the effect of expected declines in interest rates. Although other techniques could be used to reduce the Fund's exposure to interest rate fluctuations, the Fund may be able to hedge its exposure more effectively and perhaps at a lower cost by using futures contracts and futures options.

The Fund may enter into futures contracts and futures options that are standardized and traded on a U.S. or other exchange, board of trade, or similar entity, or quoted on an automated quotation system, and the Fund may also enter into OTC options on futures contracts.

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 assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees ("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. The initial margin is in the nature of a performance bond or good faith deposit on the futures contract that is returned to the Fund upon termination of the contract, assuming all contractual obligations have been satisfied. The Fund expects to earn taxable 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 does not represent a borrowing or loan by the Fund but is instead a settlement between the Fund and the broker of the amount one would owe the other if the futures

-21-

contract expired. 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, generally these obligations are closed out prior to delivery by offsetting purchases or sales of matching futures contracts (involving the same exchange, underlying security or index, and delivery month). If an offsetting purchase price is less than the original sale price, the Fund 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 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.

The Fund may write covered straddles consisting of a call and a put written on the same underlying futures contract. A straddle will be covered when sufficient assets are deposited to meet the Fund's immediate obligations. The Fund may use the same liquid assets to cover both the call and put options where the exercise price of the call and put are the same, or the exercise price of the call is higher than that of the put. In such cases, the Fund will also segregate liquid assets equivalent to the amount, if any, by which the put is "in the money."

Limitations on Use of Futures and Futures Options. As noted above, the Fund generally intends to enter into positions in futures contracts and related options only for "bona fide hedging" purposes. With respect to positions in futures and related options that do not constitute bona fide hedging positions, the Fund will not enter into a futures contract or futures option contract if, immediately thereafter, the aggregate initial margin deposits relating to such positions plus premiums paid by it for open futures option positions, less the amount by which any such options are "in the money," would exceed 5% of the Fund's liquidation value, after taking into account unrealized profits and unrealized losses on any such contracts into which the Fund has entered. A call option is "in the money" if the value of the futures contract that is the subject of the option exceeds the exercise price. A put option is "in the money" if the exercise price exceeds the value of the futures contract that is the subject of the option.

When purchasing a futures contract, the Fund will maintain with its custodian (and mark to market on a daily basis) assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, that, when added to the amounts deposited with a futures commission merchant as margin, are equal to the market value of the futures contract. Alternatively, the Fund may "cover" its position by purchasing a put option on the same futures contract with a strike price as high as or higher than the price of the contract held by the Fund.

When selling a futures contract, the Fund will maintain with its custodian (and mark to market on a daily basis) assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, that are equal to the market value of the instruments underlying the contract. Alternatively, the Fund may "cover" its position by owning the

-22-

instruments underlying the contract (or, in the case of an index futures contract, a portfolio with a volatility substantially similar to that of the index on which the futures contract is based), or by holding a call option permitting the Fund to purchase the same futures contract at a price no higher than the price of the contract written by the Fund (or at a higher price if the difference is maintained in liquid assets with the Fund's custodian).

When selling a call option on a futures contract, the Fund will maintain with its custodian (and mark to market on a daily basis) assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, that, when added to the amounts deposited with a futures commission merchant as margin, equal the total market value of the futures contract underlying the call option. Alternatively, the Fund may cover its position by entering into a long position in the same futures contract at a price no higher than the strike price of the call option, by owning the instruments underlying the futures contract, or by holding a separate call option permitting the Fund to purchase the same futures contract at a price not higher than the strike price of the call option sold by the Fund.

When selling a put option on a futures contract, the Fund will maintain with its custodian (and mark to market on a daily basis) assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, that equal the purchase price of the futures contract, less any margin on deposit. Alternatively, the Fund may cover the position either by entering into a short position in the same futures contract, or by owning a separate put option permitting it to sell the same futures contract so long as the strike price of the purchased put option is the same as or higher than the strike price of the put option sold by the Fund.

To the extent that securities with maturities greater than one year are used to segregate assets to cover the Fund's obligations under futures contracts and related options, such use will not eliminate the leverage risk arising from such use, which may tend to exaggerate the effect on net asset value of any increase or decrease in the market value of the Fund's portfolio, and may require liquidation of portfolio positions when it is not advantageous to do so.

The requirements for qualification as a regulated investment company also may limit the extent to which the Fund may enter into futures, futures options or forward contracts. See "Tax Matters."

Risks Associated with Futures and Futures Options. There are several risks associated with the use of futures contracts and futures options as hedging techniques. A purchase or sale of a futures contract may result in losses in excess of the amount invested in the futures contract. There can be no guarantee that there will be a correlation between price movements in the hedging vehicle and in the Fund securities being hedged. 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 hedge not to achieve its objectives. The degree of imperfection of correlation depends on circumstances such as variations in speculative market demand for futures and futures options on securities, including technical influences in futures trading and futures options, and differences between the financial instruments being hedged and the instruments underlying the standard contracts available for trading in such respects as interest rate levels, maturities, and creditworthiness of issuers. A decision as to whether, when and how

-23-

to hedge involves the exercise of skill and judgment, and even a well-conceived hedge may be unsuccessful to some degree because of market behavior or unexpected interest rate trends.

Futures contracts on U.S. Government securities historically have reacted to an increase or decrease in interest rates in a manner similar to that in which the underlying U.S. Government securities reacted. To the extent, however, that the Fund enters into such futures contracts, the value of such futures will not vary in direct proportion to the value of the Fund's holdings of debt obligations. Thus, the anticipated spread between the price of the futures contract and the hedged security may be distorted due to differences in the nature of the markets. The spread also may be distorted by differences in initial and variation margin requirements, the liquidity of such markets and the participation of speculators in such markets.

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.

There can be no assurance that a liquid market will exist at a time when the Fund seeks to close out a futures contract or a futures option position, and the Fund would remain obligated 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.

Additional Risks of Options on Securities, Futures Contracts, Options on Futures Contracts and Forward Currency Exchange Contracts and Options thereon. Options on securities, futures contracts, options on futures contracts, and options on currencies may be traded on foreign exchanges. Such transactions may not be regulated as effectively as similar transactions in the United States, may not involve a clearing mechanism and related guarantees, and are subject to the risk of governmental actions affecting trading in, or the prices of, foreign securities. Some foreign exchanges may be principal markets so that no common clearing facility exists and a trader may look only to the broker for performance of the contract. The value of such positions also could be adversely affected by (i) other complex foreign political, legal and economic factors,
(ii) lesser availability than in the United States of data on which to make trading decisions, (iii) delays in the Fund's ability to act upon economic events occurring in foreign markets during non-business hours in the United States, (iv) the imposition of different exercise and settlement terms and procedures and margin requirements than in the United States and (v) lesser trading volume. In addition, unless the Fund hedges against fluctuations in the exchange rate between the U.S. dollar and the currencies in which trading is done on foreign exchanges, any profits that the Fund might realize in trading could be eliminated by adverse changes in the exchange rate, or the Fund could incur losses as a result of those changes. The Fund's use of such instruments may cause the Fund to realize higher amounts of short-term

-24-

capital gains (generally taxed to shareholders at ordinary income tax rates) than if the Fund had not used such instruments.

Swap Agreements. The Fund may enter into swap agreements with respect to interest rates, currencies, indexes of securities and other assets or measures of risk or return. The Fund may also enter into options on swap agreements ("swaptions"). These transactions are entered into in an attempt to obtain a particular return when it is considered desirable to do so, possibly at a lower cost to the Fund than if the Fund had invested directly in an instrument that yielded that desired return. Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a few weeks to more than one year. In a standard "swap" transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on particular predetermined investments or instruments, which may be adjusted for an interest factor. The gross returns to be exchanged or "swapped" between the parties are generally calculated with respect to a "notional amount," i.e., the return on or increase in value of a particular dollar amount invested at a particular interest rate or in a "basket" of securities representing a particular index. Forms of swap agreements include interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or "cap"; interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified rate, or "floor"; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels. The Fund may use interest rate caps, floors and collars to a substantial degree in connection with its leveraging strategies. See "--Certain Interest Rate Transactions" below and "The Fund's Investment Objectives and Strategies--Certain Interest Rate Transactions" in the Prospectus. A swaption is a contract that gives a counterparty the right (but not the obligation) to enter into a new swap agreement or to shorten, extend, cancel or otherwise modify an existing swap agreement, at some designated future time on specified terms. The Fund may write
(sell) and purchase put and call swaptions.

Most swap agreements entered into by the Fund would calculate the obligations of the parties to the agreement on a "net basis." Consequently, the Fund's current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the "net amount"). The Fund's current obligations under a swap agreement will be accrued daily (offset against any amounts owed to the Fund). The Fund may use swap agreements to add leverage to the portfolio. The Fund, except with regard to credit default swaps, as described below, may (but is not required to) cover any accrued but unpaid net amounts owed to a swap counterparty through the segregation of assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees. Obligations under swap agreements so covered will not be construed to be "senior securities" for purposes of the Fund's investment restriction concerning senior securities and borrowings.

Whether the Fund's use of swap agreements or swaptions will be successful in furthering its investment objectives will depend on PIMCO's ability to predict correctly whether certain types of investments are likely to produce greater returns than other investments. Because they are two-party contracts and because they may have terms of greater than seven days, swap agreements may be considered to be illiquid. Moreover, the Fund bears the risk of loss of the

-25-

amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. The Fund will enter into swap agreements only with counterparties that meet certain standards of creditworthiness. The swaps market is a relatively new market and is largely unregulated. It is possible that developments in the swaps market, including potential government regulation, could adversely affect the Fund's ability to terminate existing swap agreements or to realize amounts to be received under such agreements.

Depending on the terms of the particular option agreement, the Fund will generally incur a greater degree of risk when it writes a swaption than it will incur when it purchases a swaption. When the Fund purchases a swaption, it risks losing only the amount of the premium it has paid should it decide to let the option expire unexercised. However, when the Fund writes a swaption, upon exercise of the option the Fund will become obligated according to the terms of the underlying agreement.

Certain swap agreements are exempt from most provisions of the Commodity Exchange Act ("CEA") and, therefore, are not regulated as futures or commodity option transactions under the CEA.

Certain Interest Rate Transactions. As described above, the Fund may enter into interest rate swaps and caps. Interest rate swaps involve the Fund's agreement with the swap counterparty to pay a fixed rate payment in exchange for the counterparty paying the Fund a variable rate payment that may be structured so as to approximate the Fund's variable rate payment obligation on any preferred shares of beneficial interest that the Fund may issue (the "Preferred Shares") or any variable rate borrowing. The payment obligation would be based on the notional amount of the swap. The Fund may use an interest rate cap, which would require the Fund to pay a premium to the cap counterparty and would entitle the Fund, 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 may use interest rate swaps or caps with the intent to reduce or eliminate the risk that an increase in short-term interest rates could have on the performance of the Common Shares as a result of the Fund's investments and capital structure, and may also use these instruments for other hedging purposes.

Mortgage-Related and Other Asset-Backed Securities

The Fund may invest in mortgage-related securities, and in other asset-backed securities (unrelated to mortgage loans) that are offered to investors currently or in the future. Mortgage-related securities are interests in pools of residential or commercial mortgage loans, including mortgage loans made by savings and loan institutions, mortgage bankers, commercial banks and others. Pools of mortgage loans are assembled as securities for sale to investors by various governmental, government-related and private organizations. The value of some mortgage-related or asset-backed securities in which the Fund may invest may be particularly sensitive to changes in prevailing interest rates, and, like other debt obligations, the ability of the Fund to successfully utilize these instruments may depend in part upon the ability of PIMCO to forecast interest rates and other economic factors correctly. See "--Mortgage Pass-Through Securities" below. Certain debt obligations are also secured with collateral consisting of mortgage-related securities. See "--Collateralized Mortgage Obligations ("CMOs")" below.

-26-

Commercial Mortgage-Backed Securities. Commercial mortgage-backed securities include securities that reflect an interest in, and are secured by, mortgage loans on commercial real property. The market for commercial mortgage-backed securities developed more recently and in terms of total outstanding principal amount of issues is relatively small compared to the market for residential single-family mortgage-backed securities. Many of the risks of investing in commercial mortgage-backed securities reflect the risks of investing in the real estate securing the underlying mortgage loans. These risks reflect the effects of local and other economic conditions on real estate markets, the ability of tenants to make loan payments, and the ability of a property to attract and retain tenants. Commercial mortgage-backed securities may be less liquid and exhibit greater price volatility than other types of mortgage- or asset-backed securities.

Mortgage Pass-Through Securities. Mortgage pass-through securities are securities representing interests in "pools" of mortgage loans secured by residential or commercial real property. Interests in pools of mortgage-related securities differ from other forms of debt obligations, which normally provide for periodic payment of interest in fixed amounts with principal payments at maturity or specified call dates. Instead, these securities provide a monthly payment which consists of both interest and principal payments. In effect, these payments are a "pass-through" of the monthly payments made by the individual borrowers on their residential or commercial mortgage loans, net of any fees paid to the issuer or guarantor of such securities. Additional payments are caused by repayments of principal resulting from the sale of the underlying property, refinancing or foreclosure, net of fees or costs which may be incurred. Some mortgage-related securities (such as securities issued by the Government National Mortgage Association (the "GNMA")) are described as "modified pass-through." These securities entitle the holder to receive all interest and principal payments owed on the mortgage pool, net of certain fees, at the scheduled payment dates regardless of whether or not the mortgagor actually makes the payment.

The rate of prepayments on underlying mortgages will affect the price and volatility of a mortgage-related security, and may have the effect of shortening or extending the effective maturity of the security beyond what was anticipated at the time of purchase. Early repayment of principal on some mortgage-related securities (arising from prepayments of principal due to the sale of the underlying property, refinancing, or foreclosure, net of fees and costs which may be incurred) may expose the Fund to a lower rate of return upon reinvestment of principal. Also, if a security subject to prepayment has been purchased at a premium, the value of the premium would be lost in the event of prepayment. Like other debt obligations, when interest rates rise, the value of a mortgage-related security generally will decline; however, when interest rates are declining, the value of mortgage-related securities with prepayment features may not increase as much as other debt obligations. To the extent that unanticipated rates of prepayment on underlying mortgages increase the effective maturity of a mortgage-related security, the volatility of such security can be expected to increase.

Payment of principal and interest on some mortgage pass-through securities (but not the market value of the securities themselves) may be guaranteed by the full faith and credit of the U.S. Government (in the case of securities guaranteed by the GNMA) or guaranteed by agencies or instrumentalities of the U.S. Government (in the case of securities guaranteed by the Federal National Mortgage Association (the "FNMA") or the Federal Home Loan Mortgage Corporation (the "FHLMC"). The principal governmental guarantor of mortgage-related securities is the

GNMA. GNMA is a wholly-owned U.S. Government corporation within the Department of Housing and Urban Development. GNMA is authorized to guarantee, with the full faith and credit of the U.S. Government, the timely payment of principal and interest on securities issued by institutions approved by GNMA (such as savings and loan institutions, commercial banks and mortgage bankers) and backed by pools of mortgages insured by the Federal Housing Administration (the "FHA"), or guaranteed by the Department of Veterans Affairs (the "VA").

Government-related guarantors (i.e., not backed by the full faith and credit of the U.S. Government) include the FNMA and the FHLMC. FNMA is a government-sponsored corporation owned entirely by private stockholders. It is subject to general regulation by the Secretary of Housing and Urban Development. FNMA purchases conventional (i.e., not insured or guaranteed by any government agency) residential mortgages from a list of approved sellers/servicers which include state and federally chartered savings and loan associations, mutual savings banks, commercial banks, and credit unions and mortgage bankers. Pass-through securities issued by FNMA are guaranteed as to timely payment of principal and interest by FNMA but are not backed by the full faith and credit of the U.S. Government. Instead, they are supported only by the discretionary authority of the U.S. Government to purchase the agency's obligations.

FHLMC was created by Congress in 1970 for the purpose of increasing the availability of mortgage credit for residential housing. It is a government-sponsored corporation formerly owned by the twelve Federal Home Loan Banks and now owned entirely by private stockholders. FHLMC issues Participation Certificates ("PCs") which represent interests in conventional mortgages from FHLMC's national portfolio. FHLMC guarantees the timely payment of interest and ultimate collection of principal, but PCs are not backed by the full faith and credit of the U.S. Government. Instead, they are supported only by the discretionary authority of the U.S. Government to purchase the agency's obligations.

Commercial banks, savings and loan institutions, private mortgage insurance companies, mortgage bankers and other secondary market issuers also create pass-through pools of conventional residential mortgage loans. Such issuers may, in addition, be the originators and/or servicers of the underlying mortgage loans as well as the guarantors of the mortgage-related securities. Pools created by such non-governmental issuers generally offer a higher rate of interest than government and government-related pools because there are no direct or indirect government or agency guarantees of payments in such pools. However, timely payment of interest and principal of these pools may be supported by various forms of insurance or guarantees, including individual loan, title, pool and hazard insurance and letters of credit. The insurance and guarantees are issued by governmental entities, private insurers and the mortgage poolers. There can be no assurance that the private insurers or guarantors can meet their obligations under the insurance policies or guarantee arrangements. Although the market for such securities is becoming increasingly liquid, securities issued by certain private organizations may not be readily marketable. The Fund's use of these transactions will be limited by the Fund's limitations on illiquid investments to the extent they are deemed illiquid.

Mortgage-related securities that are issued or guaranteed by the U.S. Government, its agencies or instrumentalities, are not subject to the Fund's industry concentration restriction (see "Investment Restrictions") by virtue of the exclusion from that restriction available to all U.S.

Government securities. In the case of privately issued mortgage-related securities, the Fund takes the position that mortgage-related securities do not represent interests in any particular "industry" or group of industries. The assets underlying such securities may be represented by a portfolio of first lien residential mortgages (including both whole mortgage loans and mortgage participation interests) or portfolios of mortgage pass-through securities issued or guaranteed by GNMA, FNMA or FHLMC. Mortgage loans underlying a mortgage-related security may in turn be insured or guaranteed by the FHA or the VA. In the case of private issue mortgage-related securities whose underlying assets are neither U.S. Government securities nor U.S. Government-insured mortgages, to the extent that real properties securing such assets may be located in the same geographical region, the security may be subject to a greater risk of default than other comparable securities in the event of adverse economic, political or business developments that may affect such region and, ultimately, the ability of residential homeowners to make payments of principal and interest on the underlying mortgages.

Collateralized Mortgage Obligations ("CMOs"). A CMO is a hybrid between a mortgage-backed bond and a mortgage pass-through security. Similar to a bond, interest and prepaid principal is paid, in most cases, semi-annually. CMOs may be collateralized by whole mortgage loans, but are more typically collateralized by portfolios of mortgage pass-through securities guaranteed by GNMA, FHLMC, or FNMA, and their income streams.

CMOs are structured into multiple classes, each bearing a different stated maturity. Actual maturity and average life will depend upon the prepayment experience of the collateral. CMOs provide for a modified form of call protection through a de facto breakdown of the underlying pool of mortgages according to how quickly the loans are repaid. Monthly payment of principal received from the pool of underlying mortgages, including prepayments, is first returned to investors holding the shortest maturity class. Investors holding the longer maturity classes receive principal only after the first class has been retired. An investor is partially guarded against a sooner than desired return of principal because of the sequential payments.

In a typical CMO transaction, a corporation ("issuer") issues multiple series (e.g., A, B, C, Z) of CMO bonds (the "Bonds"). Proceeds of the Bond offering are used to purchase mortgages or mortgage pass-through certificates (the "Collateral"). The Collateral is pledged to a third party trustee as security for the Bonds. Principal and interest payments from the Collateral are used to pay principal on the Bonds in the order A, B, C, Z. The Series A, B and C Bonds all bear current interest. Interest on the Series Z Bond is accrued and added to principal and a like amount is paid as principal on the Series A, B or C Bond currently being paid off. When the Series A, B and C Bonds are paid in full, interest and principal on the Series Z Bond begin to be paid currently. With some CMOs, the issuer serves as a conduit to allow loan originators (primarily builders or savings and loan associations) to borrow against their loan portfolios.

CMOs that are issued or guaranteed by the U.S. Government or by any of its agencies or instrumentalities will be considered U.S. Government securities by the Fund, while other CMOs, even if collateralized by U.S. Government securities, will have the same status as other privately issued securities for purposes of applying the Fund's diversification tests.

-29-

FHLMC Collateralized Mortgage Obligations. FHLMC CMOs are debt obligations of FHLMC issued in multiple classes having different maturity dates which are secured by the pledge of a pool of conventional mortgage loans purchased by FHLMC. Unlike FHLMC PCs, payments of principal and interest on the CMOs are made semi-annually, as opposed to monthly. The amount of principal payable on each semi-annual payment date is determined in accordance with FHLMC's mandatory sinking fund schedule, which in turn, is equal to approximately 100% of FHA prepayment experience applied to the mortgage collateral pool. All sinking fund payments in the CMOs are allocated to the retirement of the individual classes of bonds in the order of their stated maturities. Payments of principal on the mortgage loans in the collateral pool in excess of the amount of FHLMC's minimum sinking fund obligation for any payment date are paid to the holders of the CMOs as additional sinking fund payments. Because of the "pass-through" nature of all principal payments received on the collateral pool in excess of FHLMC's minimum sinking fund requirement, the rate at which principal of the CMOs is actually repaid is likely to be such that each class of bonds will be retired in advance of its scheduled maturity date.

If collection of principal (including prepayments) on the mortgage loans during any semi-annual payment period is not sufficient to meet FHLMC's minimum sinking fund obligation on the next sinking fund payment date, FHLMC agrees to make up the deficiency from its general funds.

Criteria for the mortgage loans in the pool backing the FHLMC CMOs are identical to those of FHLMC PCs. FHLMC has the right to substitute collateral in the event of delinquencies and/or defaults.

Other Mortgage-Related Securities. Other mortgage-related securities include securities other than those described above that directly or indirectly represent a participation in, or are secured by and payable from, mortgage loans on real property. Other mortgage-related securities may be equity or debt securities issued by agencies or instrumentalities of the U.S. Government or by private originators of, or investors in, mortgage loans, including savings and loan associations, homebuilders, mortgage banks, commercial banks, investment banks, partnerships, trusts and special purpose entities of the foregoing.

-30-

Other Asset-Backed Securities. Similarly, PIMCO expects that other asset-backed securities (unrelated to mortgage loans) will be offered to investors in the future and may be purchased by the Fund. Several types of asset-backed securities have already been offered to investors, including Enhanced Equipment Trust Certificates ("EETCs"), Certificates for Automobile Receivables(SM) ("CARS(SM)") and Collateralized Debt Obligations ("CDOs").

Although any entity may issue EETCs, to date, U.S. airlines are the primary issuers. An airline EETC is an obligation secured directly by aircraft or aircraft engines as collateral. Airline EETCs generally have credit enhancement in the form of overcollateralization and cross-subordination (i.e., multiple tranches and multiple aircraft as collateral). They also generally have a dedicated liquidity facility provided by a third-party insurer to insure that coupon payments are made on a timely basis until collateral is liquidated in the event of a default by the lessor of the collateral. Aircraft EETCs issued by registered U.S. carriers also benefit from a special section of the U.S. Bankruptcy Code, which allows the aircraft to be sold by the trust holding the collateral to repay note holders without participating in bankruptcy proceedings. EETCs tend to be less liquid than bonds.

CARS(SM) represent undivided fractional interests in a trust whose assets consist of a pool of motor vehicle retail installment sales contracts and security interests in the vehicles securing the contracts. Payments of principal and interest on CARS(SM) are passed through monthly to certificate holders, and are guaranteed up to certain amounts and for a certain time period by a letter of credit issued by a financial institution unaffiliated with the trustee or originator of the trust. An investor's return on CARS(SM) may be affected by early prepayment of principal on the underlying vehicle sales contracts. If the letter of credit is exhausted, the trust may be prevented from realizing the full amount due on a sales contract because of state law requirements and restrictions relating to foreclosure sales of vehicles and the obtaining of deficiency judgments following such sales or because of depreciation, damage or loss of a vehicle, the application of

-31-

federal and state bankruptcy and insolvency laws, or other factors. As a result, certificate holders may experience delays in payments or losses if the letter of credit is exhausted.

The Fund may invest in CDOs, which includes collateralized bond obligations ("CBOs"), collateralized loan obligations ("CLOs") and other similarly structured securities. CBOs and CLOs are types of asset-backed securities. A CBO is a trust which is backed by a diversified pool of high risk, below investment grade fixed income securities. A CLO is a trust typically collateralized by a pool of loans, which may include, among others, domestic and foreign senior secured loans, senior unsecured loans, and subordinate corporate loans, including loans that may be rated below investment grade or equivalent unrated loans.

For both CBOs and CLOs, the cashflows from the trust are split into two or more portions, called tranches, varying in risk and yield. The riskiest portion is the residual or "equity" tranche which bears the bulk of defaults from the bonds or loans in the trust and serves to protect the other, more senior tranches from default in all but the most severe circumstances. Since it is partially protected from defaults, a senior tranche from a CBO trust or CLO trust typically have higher ratings and lower yields than their underlying securities, and can be rated investment grade. Despite the protection from the equity tranche, CBO or CLO tranches can experience substantial losses due to actual defaults, increased sensitivity to defaults due to collateral default and disappearance of protecting tranches, market anticipation of defaults, as well as aversion to CBO or CLO securities as a class.

The risks of an investment in a CDO depend largely on the type of the collateral securities and the class of the CDO in which the Fund invests. Normally, CBOs, CLOs and other CDOs are privately offered and sold, and thus, are not registered under the securities laws. As a result, investments in CDOs may be characterized by the Fund as illiquid securities; however, an active dealer market may exist for CDOs allowing a CDO to qualify for Rule 144A transactions. In addition to the normal risks associated with fixed income securities discussed elsewhere in this Statement of Additional Information and the Prospectus (e.g., interest rate risk and default risk), CDOs carry additional risks including, but not limited to, (i) the possibility that distributions from collateral securities will not be adequate to make interest or other payments, (ii) the quality of the collateral may decline in value or default, (iii) the Fund may invest in CDOs that are subordinate to other classes, and (iv) the complex structure of the security may not be fully understood at the time of investment and may produce disputes with the issuer or unexpected investment results.

Consistent with the Fund's investment objectives and policies, PIMCO also may invest in other types of asset-backed securities. Other asset-backed securities may be collateralized by the fees earned by service providers. The value of asset-backed securities may be substantially dependent on the servicing of the underlying asset pools and are therefore subject to risks associated with the negligence by, or defalcation of, their servicers. In certain circumstances, the mishandling of related documentation may also affect the rights of the security holders in and to the underlying collateral. The insolvency of entities that generate receivables or that utilize the assets may result in added costs and delays in addition to losses associated with a decline in the value of the underlying assets.

-32-

Variable and Floating Rate Securities

Variable and floating rate securities provide for a periodic adjustment in the interest rate paid on the obligations. The terms of such obligations must provide that interest rates are adjusted periodically based upon an interest rate adjustment index as provided in the respective obligations. The adjustment intervals may be regular, and range from daily up to annually, or may be event based, such as based on a change in the prime rate.

The Fund may invest in floating rate debt instruments ("floaters") and engage in credit spread trades. The interest rate on a floater is a variable rate that is tied to another interest rate, such as a bond index or Treasury bill rate. The interest rate on a floater resets periodically, typically every six months. While, because of the interest rate reset feature, floaters provide the Fund with a certain degree of protection against rising interest rates, the Fund will participate in any declines in interest rates. A credit spread trade is an investment position relating to a difference in the prices or interest rates of two bonds or other securities, where the value of the investment position is determined by movements in the difference between the prices or interest rates, as the case may be, of the respective securities or currencies.

Inflation-Indexed Bonds

The Fund may invest in inflation-indexed bonds, which are debt obligations whose value is periodically adjusted according to the rate of inflation. Two structures are common. The U.S. Treasury and some other issuers utilize a structure that accrues inflation into the principal value of the bond. Most other issuers pay out the Consumer Price Index accruals as part of a semiannual coupon.

Inflation-indexed securities issued by the U.S. Treasury have maturities of approximately five, ten or thirty years, although it is possible that securities with other maturities will be issued in the future. The U.S. Treasury securities pay interest on a semi-annual basis equal to a fixed percentage of the inflation-adjusted principal amount. For example, if the Fund purchased an inflation-indexed bond with a par value of $1,000 and a 3% real rate of return coupon (payable 1.5% semi-annually), and the rate of inflation over the first six months was 1%, the mid-year par value of the bond would be $1,010 and the first semi-annual interest payment would be $15.15 ($1,010 times 1.5%). If inflation during the second half of the year resulted in the whole year's inflation equaling 3%, the end-of-year par value of the bond would be $1,030 and the second semi-annual interest payment would be $15.45 ($1,030 times 1.5%).

If the periodic adjustment rate measuring inflation falls, the principal value of inflation-indexed bonds will be adjusted downward, and consequently the interest payable on these securities (calculated with respect to a smaller principal amount) will be reduced. Repayment of the original bond principal upon maturity (as adjusted for inflation) is guaranteed in the case of U.S. Treasury inflation-indexed bonds, even during a period of deflation. However, the current market value of the bonds is not guaranteed and will fluctuate. The Fund may also invest in other inflation-related bonds which may or may not provide a similar guarantee. If a guarantee of principal is not provided, the adjusted principal value of the bond repaid at maturity may be less than the original principal amount.

-33-

The value of inflation-indexed bonds is expected to change in response to changes in real interest rates. Real interest rates in turn are tied to the relationship between nominal interest rates and the rate of inflation. Therefore, if the rate of inflation rises at a faster rate than nominal interest rates, real interest rates might decline, leading to an increase in value of inflation-indexed bonds. In contrast, if nominal interest rates increase at a faster rate than inflation, real interest rates might rise, leading to a decrease in value of inflation-indexed bonds.

While these securities are expected to be protected from long-term inflationary trends, short-term increases in inflation may lead to a decline in value. If interest rates rise due to reasons other than inflation (for example, due to changes in currency exchange rates), investors in these securities may not be protected to the extent that the increase is not reflected in the bond's inflation measure.

The periodic adjustment of U.S. inflation-indexed bonds is tied to the Consumer Price Index for Urban Consumers ("CPI-U"), which is calculated monthly by the U.S. Bureau of Labor Statistics. The CPI-U is a measurement of changes in the cost of living, made up of components such as housing, food, transportation and energy. Inflation-indexed bonds issued by a foreign government are generally adjusted to reflect a comparable inflation index calculated by that government. There can be no assurance that the CPI-U or any foreign inflation index will accurately measure the real rate of inflation in the prices of goods and services. Moreover, there can be no assurance that the rate of inflation in a foreign country will be correlated to the rate of inflation in the United States.

For federal income tax purposes, any increase in the principal amount of an inflation-indexed bond will be original issue discount which is taxable as ordinary income in the year accrued, even though investors do not receive their principal, including any increases thereto, until maturity. See "Tax Matters-- Discount Obligations and Payment-in-Kind Securities" below.

Event-Linked Bonds

The Fund may invest in "event-linked bonds." Event-linked bonds, which are sometimes referred to as "catastrophe bonds," are debt obligations for which the return of principal and payment of interest is contingent on the non-occurrence of a specific "trigger" event, such as a hurricane or an earthquake. They may be issued by government agencies, insurance companies, reinsurers, special purpose corporations or other on-shore or off-shore entities. If a trigger event causes losses exceeding a specific amount in the geographic region and time period specified in a bond, the Fund may lose a portion or all of its principal invested in the bond. If no trigger event occurs, the Fund will recover its principal plus interest. For some event-linked bonds, the trigger event or losses may be based on company-wide losses, index-portfolio losses, industry indexes or readings of scientific instruments rather than specified actual losses. Often event-linked bonds provide for extensions of maturity that are mandatory, or optional at the discretion of the issuer, in order to process and audit loss claims in those cases when a trigger event has, or possibly has, occurred. In addition to the specified trigger events, event-linked bonds may also expose the Fund to certain unanticipated risks including but not limited to issuer (credit) default, adverse regulatory or jurisdictional interpretations and adverse tax consequences.

Event-linked bonds are a relatively new type of financial instrument. As such, there is no significant trading history of these securities, and there can be no assurance that a liquid market in these instruments will develop. Lack of a liquid market may impose the risk of higher

-34-

transaction costs and the possibility that the Fund may be forced to liquidate positions when it would not be advantageous to do so. Event-linked bonds are typically rated.

Delayed Funding Loans and Revolving Credit Facilities

The Fund may also enter into, or acquire participations in, delayed funding loans and revolving credit facilities. Delayed funding loans and revolving credit facilities are borrowing arrangements in which the lender agrees to make loans up to a maximum amount upon demand by the borrower during a specified term. A revolving credit facility differs from a delayed funding loan in that as the borrower repays the loan, an amount equal to the repayment may be borrowed again during the term of the revolving credit facility. Delayed funding loans and revolving credit facilities usually provide for floating or variable rates of interest. These commitments may have the effect of requiring the Fund to increase its investment in a company at a time when it might not otherwise be desirable to do so (including a time when the company's financial condition makes it unlikely that such amounts will be repaid). To the extent that the Fund is committed to advance additional funds, it will at all times segregate assets, determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, in an amount sufficient to meet such commitments.

The Fund may invest in delayed funding loans and revolving credit facilities with credit quality comparable to that of issuers of its securities investments. Delayed funding loans and revolving credit facilities may be subject to restrictions on transfer, and only limited opportunities may exist to resell such instruments. As a result, the Fund may be unable to sell such investments at an opportune time or may have to resell them at less than fair market value. The Fund currently intends to treat delayed funding loans and revolving credit facilities for which there is no readily available market as illiquid for purposes of the Fund's limitation on illiquid investments. For a further discussion of the risks involved in investing in loan participations and other forms of direct indebtedness see "--Loan Participations and Assignments." Participation interests in revolving credit facilities will be subject to the limitations discussed in "--Loan Participations and Assignments." Delayed funding loans and revolving credit facilities are considered to be debt obligations for the purposes of the Fund's investment restriction relating to the lending of funds or assets by the Fund.

Structured Notes and Other Hybrid Instruments

The Fund may invest in "structured" notes, which are privately negotiated debt obligations where the principal and/or interest is determined by reference to the performance of a benchmark asset, market or interest rate, such as selected securities, an index of securities or specified interest rates, or the differential performance of two assets or markets, such as indexes reflecting bonds. Depending on the terms of the note, the Fund may forgo all or part of the interest and principal that would be payable on a comparable conventional note. The rate of return on structured notes may be determined by applying a multiplier to the performance or differential performance of the referenced index(es) or other asset(s). Application of a multiplier involves leverage which will serve to magnify the potential for gain and the risk of loss. The Fund may use structured notes to add leverage to the portfolio and for investment as well as risk management purposes, such as to reduce the interest rate sensitivity of the Fund's portfolio (and thereby decrease the Fund's exposure to interest rate risk). Like other sophisticated strategies,

-35-

the Fund's use of structured notes may not work as intended; for example, by reducing the duration of the Fund's portfolio, structured notes may limit the Fund's return when having a longer duration would be beneficial (for instance, when interest rates decline). Although structured instruments are not necessarily illiquid, PIMCO believes that currently most structured instruments are illiquid.

The Fund may invest in other types of "hybrid" instruments which combine the characteristics of securities, futures, and options. For example, the principal amount or interest rate of a hybrid could be tied (positively or negatively) to the price of some commodity, currency or securities index or another interest rate (each a "benchmark"). The interest rate or (unlike most debt obligations) the principal amount payable at maturity of a hybrid security may be increased or decreased, depending on changes in the value of the benchmark. Hybrids can be used as an efficient means of pursuing a variety of investment goals, including duration management and increased total return. Hybrids may not bear interest or pay dividends. The value of a hybrid or its interest rate may be a multiple of a benchmark and, as a result, may be leveraged and move (up or down) more steeply and rapidly than the benchmark. These benchmarks may be sensitive to economic and political events that cannot be readily foreseen by the purchaser of a hybrid. Under certain conditions, the redemption value of a hybrid could be zero. Thus, an investment in a hybrid may entail significant market risks that are not associated with a similar investment in a traditional, U.S. dollar-denominated bond that has a fixed principal amount and pays a fixed rate or floating rate of interest. The purchase of hybrids also exposes the Fund to the credit risk of the issuer of the hybrids. These risks may cause significant fluctuations in the net asset value of the Fund.

Certain issuers of structured products such as hybrid instruments may be deemed to be investment companies as defined in the Investment Company Act of 1940, as amended (the "1940 Act"). As a result, the Fund's investments in these products may be subject to limits applicable to investments in investment companies and may be subject to restrictions contained in the 1940 Act.

Reverse Repurchase Agreements

The Fund may enter into reverse repurchase agreements and economically similar transactions in order to add leverage to the portfolio or for hedging or cash management purposes. A reverse repurchase agreement involves the sale of a portfolio-eligible security by the Fund, coupled with its agreement to repurchase the instrument at a specified time and price. Under a reverse repurchase agreement, the Fund continues to receive any principal and interest payments on the underlying security during the term of the agreement. Reverse repurchase agreements involve leverage risk and the risk that the market value of securities retained by the Fund may decline below the repurchase price of the securities sold by the Fund which it is obligated to repurchase. The Fund may (but is not required to) segregate assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, equal (on a daily mark-to-market basis) to its obligations under reverse repurchase agreements. To the extent that positions in reverse repurchase agreements are not so covered, such transactions would be subject to the Fund's limitations on borrowings, which would, among other things, restrict the aggregate of such transactions (plus any other borrowings) to one-third of the Fund's total assets.

-36-

The Fund also may effect simultaneous purchase and sale transactions that are known as "sale-buybacks." A sale-buyback is similar to a reverse repurchase agreement, except that in a sale-buyback, the counterparty who purchases the security is entitled to receive any principal or interest payments made on the underlying security pending settlement of the Fund's repurchase of the underlying security.

Repurchase Agreements

For the purposes of maintaining liquidity and achieving income, the Fund may enter into repurchase agreements with domestic commercial banks or registered broker/dealers. A repurchase agreement is a contract under which the Fund would acquire a security for a relatively short period (usually not more than one week) subject to the obligation of the seller to repurchase and the Fund to resell such security at a fixed time and price (representing the Fund's cost plus interest). In the case of repurchase agreements with broker-dealers, the value of the underlying securities (or collateral) will be at least equal at all times to the total amount of the repurchase obligation, including the interest factor. The Fund bears a risk of loss in the event that the other party to a repurchase agreement defaults on its obligations and the Fund is delayed or prevented from exercising its rights to dispose of the collateral securities. This risk includes the risk of procedural costs or delays in addition to a loss on the securities if their value should fall below their repurchase price. PIMCO will monitor the creditworthiness of the counter parties.

U.S. Government Securities

U.S. Government securities are obligations of, or guaranteed by, the U.S. Government, its agencies or instrumentalities. The U.S. Government does not guarantee the net asset value of the Fund's shares. Some U.S. Government securities, such as Treasury bills, notes and bonds, and securities guaranteed by the GNMA, are supported by the full faith and credit of the United States; others, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Treasury; others, such as those of the FNMA, are supported by the discretionary authority of the U.S. Government to purchase the agency's obligations; and still others, such as those of the Student Loan Marketing Association, are supported only by the credit of the instrumentality. U.S. Government securities include securities that have no coupons, or have been stripped of their unmatured interest coupons, individual interest coupons from such securities that trade separately, and evidences of receipt of such securities. Such securities may pay no cash income, and are purchased at a deep discount from their value at maturity. See "--Zero-Coupon Bonds, Step-Ups and Payment-In-Kind Securities." Custodial receipts issued in connection with so-called trademark zero-coupon securities, such as CATs and TIGRs, are not issued by the U.S. Treasury, and are therefore not U.S. Government securities, although the underlying bond represented by such receipt is a debt obligation of the U.S. Treasury. Other zero-coupon Treasury securities (e.g., STRIPs and CUBEs) are direct obligations of the U.S. Government.

Municipal Bonds

The Fund may invest in municipal bonds which pay interest that, in the opinion of bond counsel to the issuer (or on the basis of other authority believed by PIMCO to be reliable), is

-37-

exempt from federal income taxes ("municipal bonds"), although dividends that the Fund pays that are attributable to such interest will not be tax-exempt to shareholders of the Fund.

Municipal bonds share the attributes of debt obligations in general, but are generally issued by states, municipalities and other political subdivisions, agencies, authorities and instrumentalities of states and multi-state agencies or authorities. The municipal bonds that the Fund may purchase include general obligation bonds and limited obligation bonds (or revenue bonds), including industrial development bonds issued pursuant to former federal tax law. General obligation bonds are obligations involving the credit of an issuer possessing taxing power and are payable from such issuer's general revenues and not from any particular source. Limited obligation bonds are payable only from the revenues derived from a particular facility or class of facilities or, in some cases, from the proceeds of a special excise or other specific revenue source. Tax-exempt private activity bonds and industrial development bonds generally are also revenue bonds and thus are not payable from the issuer's general revenues. The credit and quality of private activity bonds and industrial development bonds are usually related to the credit of the user of the facilities. Payment of interest on and repayment of principal of such bonds is the responsibility of the user (and/or any guarantor).

Municipal bonds are subject to credit and market risk. Generally, prices of higher quality issues tend to fluctuate less with changes in market interest rates than prices of lower quality issues and prices of longer maturity issues tend to fluctuate more than prices of shorter maturity issues. Prices and yields on municipal bonds are dependent on a variety of factors, including general money-market conditions, the financial condition of the issuer, general conditions of the municipal bond market, the size of a particular offering, the maturity of the obligation and the rating of the issue. A number of these factors, including the ratings of particular issues, are subject to change from time to time. Information about the financial condition of an issuer of municipal bonds may not be as extensive as that which is made available by corporations whose securities are publicly traded. Obligations of issuers of municipal bonds are subject to the provisions of bankruptcy, insolvency and other laws, such as the Federal Bankruptcy Reform Act of 1978, affecting the rights and remedies of creditors. Congress or state legislatures may seek to extend the time for payment of principal or interest, or both, or to impose other constraints upon enforcement of such obligations. There is also the possibility that as a result of litigation or other conditions, the power or ability of issuers to meet their obligations for the payment of interest and principal on their municipal bonds may be materially affected or their obligations may be found to be invalid or unenforceable.

When-Issued, Delayed Delivery and Forward Commitment Transactions

The Fund may purchase or sell securities on a when-issued, delayed delivery, or forward commitment basis. When such purchases are outstanding, the Fund will segregate until the settlement date assets determined to be liquid by PIMCO in accordance with procedures established by the Board of Trustees, in an amount sufficient to meet the purchase price. Typically, no income accrues on securities the Fund has committed to purchase prior to the time delivery of the securities is made, although the Fund may earn income on securities it has segregated.

-38-

When purchasing a security on a when-issued, delayed delivery, or forward commitment basis, the Fund assumes the rights and risks of ownership of the security, including the risk of price and yield fluctuations, and takes such fluctuations into account when determining its net asset value. Because the Fund is not required to pay for the security until the delivery date, these risks are in addition to the risks associated with the Fund's other investments. If the Fund remains substantially fully invested at a time when when-issued, delayed delivery, or forward commitment purchases are outstanding, the purchases may result in a form of leverage.

When the Fund has sold a security on a when-issued, delayed delivery, or forward commitment basis, the Fund does not participate in future gains or losses with respect to the security. If the other party to a transaction fails to deliver or pay for the securities, the Fund could miss a favorable price or yield opportunity or could suffer a loss. The Fund may dispose of or renegotiate a transaction after it is entered into, and may sell when-issued, delayed delivery or forward commitment securities before they are delivered, which may result in a capital gain or loss. There is no percentage limitation on the extent to which the Fund may purchase or sell securities on a when-issued, delayed delivery, or forward commitment basis.

Borrowing

The Fund may borrow money to the extent permitted under the 1940 Act as interpreted, modified or otherwise permitted by regulatory authority having jurisdiction, from time to time. The Fund may from time to time borrow money to add leverage to the portfolio. The Fund may also borrow money for temporary administrative purposes.

Under the 1940 Act, the Fund generally is not permitted to engage in borrowings unless immediately after a borrowing the value of the Fund's total assets less liabilities (other than the borrowing) is at least 300% of the principal amount of such borrowing (i.e., such principal amount may not exceed 33 1/3% of the Fund's total assets). In addition, the Fund is not permitted to declare any cash dividend or other distribution on Common Shares unless, at the time of such declaration, the value of the Fund's total assets, less liabilities other than borrowing, is at least 300% of such principal amount. If the Fund borrows it intends, to the extent possible, to prepay all or a portion of the principal amount of the borrowing to the extent necessary in order to maintain the required asset coverage. Failure to maintain certain asset coverage requirements could result in an event of default and entitle the holders of Preferred Shares ("Preferred Shareholders") and holders of any other senior securities of the Fund to elect a majority of the Trustees of the Fund.

As described in the Prospectus, the Fund may also enter into transactions that may give rise to a form of leverage. Such transactions may include, among others, reverse repurchase agreements, loans of portfolio securities, credit default swap contracts and other derivatives, as well as when-issued, delayed delivery or forward commitment transactions. To mitigate leverage risk from such transactions, the Fund will segregate liquid assets against or otherwise cover its future obligations under such transactions, to the extent that, immediately after entering into such a transaction, the Fund's future commitments that it has not segregated liquid assets against or otherwise covered, together with any outstanding Preferred Shares, would exceed 38% of the Fund's total assets. The Fund's use of these transactions may also be limited by the Fund's limitations on illiquid investments to the extent they are determined to be illiquid. See

-39-

"The Fund's Investment Objectives and Strategies--Portfolio Contents and Other Information," "Risks--Liquidity Risk" and "Preferred Shares and Related Leverage" in the Prospectus.

As described above, the Fund will, under certain circumstances, cover its commitment under these instruments by the segregation of assets determined to be liquid by PIMCO in accordance with procedures adopted by the Trustees, equal in value to the amount of the Fund's commitment, or by entering into offsetting transactions or owning positions covering its obligations. In such cases, the instruments will not be considered "senior securities" under the 1940 Act for purposes of the asset coverage requirements otherwise applicable to borrowings by the Fund or the Fund's issuance of Preferred Shares. Borrowing will tend to exaggerate the effect on net asset value of any increase or decrease in the market value of the Fund's portfolio. Money borrowed will be subject to interest costs which may or may not be recovered by appreciation of the securities purchased. The Fund also may be required to maintain minimum average balances in connection with such borrowing 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.

Mortgage Dollar Rolls

A "mortgage dollar roll" is similar to a reverse repurchase agreement in certain respects. In a "dollar roll" transaction, the Fund sells a mortgage-related security, such as a security issued by GNMA, to a dealer and simultaneously agrees to repurchase a similar security (but not the same security) in the future at a pre-determined price. A "dollar roll" can be viewed, like a reverse repurchase agreement, as a collateralized borrowing in which the Fund pledges a mortgage-related security to a dealer to obtain cash. However, unlike reverse repurchase agreements, the dealer with which the Fund enters into a dollar roll transaction is not obligated to return the same securities as those originally sold by the Fund, but only securities which are "substantially identical." To be considered "substantially identical," the securities returned to the Fund generally must: (1) be collateralized by the same types of underlying mortgages; (2) be issued by the same agency and be part of the same program; (3) have a similar original stated maturity; (4) have identical net coupon rates; (5) have similar market yields (and therefore price); and (6) satisfy "good delivery" requirements, meaning that the aggregate principal amounts of the securities delivered and received back must be within 2.5% of the initial amount delivered.

As with reverse repurchase agreements, to the extent that positions in dollar roll agreements are not covered by segregated liquid assets at least equal to the amount of any forward purchase commitment, such transactions would be subject to the Fund's restrictions on borrowings. Furthermore, because dollar roll transactions may be for terms ranging between one and six months, dollar roll transactions may be deemed "illiquid" and subject to the Fund's overall limitations on investments in illiquid securities.

Short Sales

The Fund may make short sales of securities as part of its overall portfolio management strategy and to offset potential declines in long positions in securities in the Fund's portfolio. A short sale is a transaction in which the Fund sells a security it does not own in anticipation that the market price of that security will decline.

-40-

When the Fund makes a short sale on a security, it must borrow the security sold short and deliver it to the broker-dealer through which it made the short sale as collateral for its obligation to deliver the security upon conclusion of the sale. The Fund may have to pay a fee to borrow particular securities and is often obligated to pay over any accrued interest and dividends on such borrowed securities.

If the price of the security sold short increases between the time of the short sale and the time the Fund replaces the borrowed security, the Fund will incur a loss; conversely, if the price declines, the Fund will realize a capital gain. Any gain will be decreased, and any loss increased, by the transaction costs described above. The successful use of short selling may be adversely affected by imperfect correlation between movements in the price of the security sold short and the securities being hedged.

To the extent that the Fund engages in short sales, it will provide collateral to the broker-dealer. A short sale is "against the box" to the extent that the Fund contemporaneously owns, or has the right to obtain at no added cost, securities identical to those sold short. The Fund may engage in so-called "naked" short sales where it does not own or have the immediate right to acquire the security sold short at no additional cost, in which case the Fund's losses could theoretically be unlimited, provided that the Fund will not engage in such naked short sales in excess of 5% of the Fund's total assets and that the Fund will not engage in any such naked short sales within 90 days from the date of the Prospectus.

Illiquid Securities

The Fund may invest up to 15% of its total assets in illiquid securities (i.e., securities that cannot be disposed of within seven days in the ordinary course of business at approximately the value at which the Fund has valued the securities). For these purposes, bank loans that are part of an issue of at least $250 million in par value will not be considered illiquid, although the Fund's investments in such bank loans, together with its investments in illiquid securities, will not exceed 20% of its total assets. Illiquid securities are considered to include, among other things, written over-the-counter options, securities or other liquid assets being used as cover for such options, repurchase agreements with maturities in excess of seven days, certain loan participation interests, fixed time deposits which are not subject to prepayment or provide for withdrawal penalties upon prepayment (other than overnight deposits), and other securities whose disposition is restricted under the federal securities laws (other than securities issued pursuant to Rule 144A under the 1933 Act and certain commercial paper that PIMCO has determined to be liquid under procedures approved by the Board of Trustees).

Illiquid securities may include privately placed securities, which are sold directly to a small number of investors, usually institutions. Unlike public offerings, such securities are not registered under the federal securities laws. Although certain of these securities may be readily sold, others may be illiquid, and their sale may involve substantial delays and additional costs.

Portfolio Trading and Turnover Rate

Portfolio trading may be undertaken to accomplish the investment objectives of the Fund in relation to actual and anticipated movements in interest rates. In addition, a security may be

-41-

sold and another of comparable quality purchased at approximately the same time to take advantage of what PIMCO believes to be a temporary price disparity between the two securities. Temporary price disparities between two comparable securities may result from supply and demand imbalances where, for example, a temporary oversupply of certain bonds may cause a temporarily low price for such bonds, as compared with other bonds of like quality and characteristics. The Fund may also engage in short-term trading consistent with its investment objectives. Securities may be sold in anticipation of a market decline (a rise in interest rates) or purchased in anticipation of a market rise (a decline in interest rates) and later sold, or to recognize a gain.

A change in the securities held by the Fund is known as "portfolio turnover." PIMCO manages the Fund without regard generally to restrictions on portfolio turnover. The use of certain derivative instruments with relatively short maturities may tend to exaggerate the portfolio turnover rate for the Fund. Trading in debt obligations does not generally involve the payment of brokerage commissions, but does involve indirect transaction costs. The use of futures contracts may involve the payment of commissions to futures commission merchants. High portfolio turnover (e.g., greater than 100%) involves correspondingly greater expenses to the Fund, including brokerage commissions or dealer mark-ups and other transaction costs on the sale of securities and reinvestments in other securities. The higher the rate of portfolio turnover of the Fund, the higher these transaction costs borne by the Fund generally will be. Transactions in the Fund's portfolio securities may result in realization of taxable capital gains (including short-term capital gains which are generally taxed to shareholders at ordinary income tax rates). The trading costs and tax effects associated with portfolio turnover may adversely affect the Fund's performance.

The portfolio turnover rate of the Fund is calculated by dividing (a) the lesser of purchases or sales of portfolio securities for the particular fiscal year by (b) the monthly average of the value of the portfolio securities owned by the Fund during the particular fiscal year. In calculating the rate of portfolio turnover, there is excluded from both (a) and (b) all securities, including options, whose maturities or expiration dates at the time of acquisition were one year or less.

Warrants to Purchase Securities

The Fund may invest in warrants to purchase debt securities. Debt obligations with warrants attached to purchase equity securities have many characteristics of convertible bonds and their prices may, to some degree, reflect the performance of the underlying stock. Debt obligations also may be issued with warrants attached to purchase additional debt securities at the same coupon rate. A decline in interest rates would permit the Fund to buy additional bonds at the favorable rate or to sell the warrants at a profit. If interest rates rise, the warrants would generally expire with no value.

Securities Loans

Subject to the Fund's "Investment Restrictions" listed below, the Fund may make secured loans of its portfolio securities to brokers, dealers and other financial institutions amounting to no more than one-third of its total assets. The risks in lending portfolio securities, as with other

-42-

extensions of credit, consist of possible delay in recovery of the securities or possible loss of rights in the collateral should the borrower fail financially. However, such loans will be made only to broker-dealers that are believed by PIMCO to be of relatively high credit standing. Securities loans are made to broker-dealers pursuant to agreements requiring that loans be continuously secured by collateral consisting of U.S. Government securities, cash or cash equivalents (negotiable certificates of deposit, bankers' acceptances or letters of credit) maintained on a daily mark-to-market basis in an amount at least equal at all times to the market value of the securities lent. The borrower pays to the Fund, as the lender, an amount equal to any dividends or interest received on the securities lent. The Fund may invest only the cash collateral received in interest-bearing, short-term securities or receive a fee from the borrower. In the case of cash collateral, the Fund typically pays a rebate to the lender. Although voting rights or rights to consent with respect to the loaned securities pass to the borrower, the Fund, as the lender, retains the right to call the loans and obtain the return of the securities loaned at any time on reasonable notice, and it will do so in order that the securities may be voted by the Fund if the holders of such securities are asked to vote upon or consent to matters materially affecting the investment. The Fund may also call such loans in order to sell the securities involved. When engaged in securities lending, the Fund's performance will continue to reflect changes in the value of the securities loaned and will also reflect the receipt of either interest, through investment of cash collateral by the Fund in permissible investments, or a fee, if the collateral is U.S. Government securities.

Participation on Creditors Committees

The Fund may from time to time participate on committees formed by creditors to negotiate with the management of financially troubled issuers of securities held by the Fund. Such participation may subject the Fund to expenses such as legal fees and may make the Fund an "insider" of the issuer for purposes of the federal securities laws, and therefore may restrict the Fund's ability to trade in or acquire additional positions in a particular security when it might otherwise desire to do so. Participation by the Fund on such committees also may expose the Fund to potential liabilities under the federal bankruptcy laws or other laws governing the rights of creditors and debtors. The Fund would participate on such committees only when PIMCO believes that such participation is necessary or desirable to enforce the Fund's rights as a creditor or to protect the value of securities held by the Fund.

Short-Term Investments / Temporary Defensive Strategies

Upon PIMCO's recommendation, for temporary defensive purposes and in order to keep the Fund's cash fully invested, including the period during which the net proceeds of the offering are being invested, the Fund may invest up to 100% of its net assets in investment grade debt securities, including high quality, short-term debt instruments. Such investments may prevent the Fund from achieving its investment objectives.

INVESTMENT RESTRICTIONS

Fundamental Investment Restrictions

Except as described below, the Fund, as a fundamental policy, may not, without the approval of the holders of a majority of the outstanding Common Shares and any outstanding preferred shares of beneficial interest of the Fund (including Preferred Shares) voting together as a single class, and of the holders of a majority of any outstanding preferred shares of beneficial interest of the Fund (including the Preferred Shares) voting as a separate class:

(1) Concentrate its investments in a particular "industry," as that term is used in the Investment Company Act of 1940, as amended, and as interpreted, modified, or otherwise permitted by regulatory authority having jurisdiction, from time to time.

(2) With respect to 75% of the Fund's total assets, purchase the securities of any issuer, except securities issued or guaranteed by the U.S. Government or any of its agencies or instrumentalities or securities issued by other investment companies, if, as a result, (i) more than 5% of the Fund's total assets would be invested in the securities of that issuer, or (ii) the Fund would hold more than 10% of the outstanding voting securities of that issuer. For the purpose of this restriction, each state and each separate political subdivision, agency, authority or instrumentality of such state, each multi-state agency or authority, and each obligor, if any, is treated as a separate issuer of municipal bonds.

(3) Purchase or sell real estate, although it may purchase securities secured by real estate or interests therein, or securities issued by companies which invest in real estate, or interests therein.

(4) Purchase or sell commodities or commodities contracts or oil, gas or mineral programs. This restriction shall not prohibit the Fund, subject to restrictions described in the Prospectus and elsewhere in this Statement of Additional Information, from purchasing, selling or entering into futures contracts, options on futures contracts, forward contracts, or any interest rate, securities-related or other hedging instrument, including swap agreements and other derivative instruments, subject to compliance with any applicable provisions of the federal securities or commodities laws.

(5) Borrow money or issue any senior security, except to the extent permitted under the Investment Company Act of 1940, as amended, and as interpreted, modified, or otherwise permitted by regulatory authority having jurisdiction, from time to time.

(6) Make loans, except to the extent permitted under the Investment Company Act of 1940, as amended, and as interpreted, modified, or otherwise permitted by regulatory authority having jurisdiction, from time to time.

(7) Act as an underwriter of securities of other issuers, except to the extent that in connection with the disposition of portfolio securities, it may be deemed to be an underwriter under the federal securities laws.

-44-

Currently, under the 1940 Act, the Fund generally is not permitted to engage in borrowings unless immediately after a borrowing the value of the Fund's total assets less liabilities (other than the borrowing) is at least 300% of the principal amount of such borrowing (i.e., such principal amount may not exceed 33 1/3% of the Fund's total assets). In addition, the Fund is not permitted to declare any cash dividend or other distribution on Common Shares unless, at the time of such declaration, the value of the Fund's total assets, less liabilities other than the borrowing, is at least 300% of such principal amount.

Currently, under the 1940 Act, the Fund may generally not 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' and qualifying shares.

For purposes of the foregoing and "Description of Shares--Preferred Shares--Voting Rights" below, "majority of the outstanding," when used with respect to particular shares of the Fund (whether voting together as a single class or voting as separate classes), means (i) 67% or more of such shares present at a meeting, if the holders of more than 50% of such shares are present or represented by proxy, or (ii) more than 50% of such shares, whichever is less.

Unless otherwise indicated, all limitations applicable to the Fund's investments (as stated above and elsewhere in this Statement of Additional Information) apply only at the time a transaction is entered into. Any subsequent change in a rating assigned by any rating service to a security (or, if unrated, deemed by PIMCO to be of comparable quality), or change in the percentage of the Fund's total assets invested in certain securities or other instruments, or change in the average maturity or duration of the Fund's investment portfolio, resulting from market fluctuations or other changes in the Fund's total assets, will not require the Fund to dispose of an investment until PIMCO determines that it is practicable to sell or close out the investment without undue market or tax consequences to the Fund. In the event that rating agencies assign different ratings to the same security, PIMCO will determine which rating it believes best reflects the security's quality and risk at that time, which may be the higher of the several assigned ratings.

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.

The Fund would be deemed to "concentrate" in a particular industry if it invested 25% or more of its total assets in that industry. The Fund's industry concentration policy does not preclude it from focusing investments in issuers in a group of related industrial sectors (such as different types of utilities).

The Fund may not change its policy to invest at least 80% of its net assets (plus any borrowing for investment purposes) in debt securities that are rated below investment grade (below Baa by Moody's, below BBB by either S&P or Fitch Ratings, or below a comparable rating by Dominion) or unrated but judged by PIMCO to be of comparable quality, unless it provides shareholders with at least 60 days' written notice of such change.

-45-

To the extent the Fund covers its commitment under a reverse repurchase agreement, credit default swap or other derivative instrument by the segregation of assets determined by PIMCO to be liquid in accordance with procedures adopted by the Trustees, equal in value to the amount of the Fund's commitment, such instrument will not be considered a "senior security" for purposes of the asset coverage requirements otherwise applicable to borrowings by the Fund or the Fund's issuance of Preferred Shares.

The Fund interprets its policies with respect to borrowing and lending to permit such activities as may be lawful for the Fund, to the full extent permitted by the 1940 Act or by exemption from the provisions therefrom pursuant to exemptive order of the SEC.

It is a condition of the issuance of the Preferred Shares that they be issued with a credit quality rating of "Aaa" from Moody's and "AAA" from Fitch Ratings. In order to obtain and maintain the required ratings, the Fund will be required to comply with investment quality, diversification and other guidelines established by Moody's and Fitch Ratings. Such guidelines will likely be more restrictive than the restrictions set forth above. The Fund does not anticipate that such guidelines would have a material adverse effect on holders of the Common Shares ("Common Shareholders") or its ability to achieve its investment objectives. Moody's and Fitch Ratings receive fees in connection with their ratings issuances.

MANAGEMENT OF THE FUND

Trustees and Officers

The business of the Fund is managed under the direction of the Fund's Board of Trustees. Subject to the provisions of the Fund's Amended and Restated Agreement and Declaration of Trust (the "Declaration"), its Bylaws and Massachusetts law, the Trustees have all powers necessary and convenient to carry out this responsibility, including the election and removal of the Fund's officers.

The Trustees and officers of the Fund, their ages, the position they hold with the Fund, their term of office and length of time served, a description of their principal occupations during the past five years, the number of portfolios in the fund complex (as defined in SEC regulations) that the Trustee oversees and any other directorships held by the Trustee are listed in the two tables immediately following. Except as shown, each Trustee's and officer's principal occupation and business experience for the last five years have been with the employer(s) indicated, although in some cases the Trustee may have held different positions with such employer(s). Unless otherwise indicated, the business address of the persons listed below is c/o PIMCO Advisors Fund Management LLC, 1345 Avenue of the Americas, New York, New York 10105.

Interested Trustees

Currently no Trustees are treated as "interested persons" (as defined in Section 2(a)(19) of the 1940 Act) of the Fund.

In accordance with the Fund's staggered board (see "Anti-Takeover and Other Provisions in the Declaration of Trust"), the Common Shareholders of the Fund will elect Trustees to fill the vacancies of Trustees whose terms expire at each annual meeting of Common Shareholders, unless any preferred shares of beneficial interest are outstanding, in which event the holders of the preferred shares, voting as a separate class, will elect two Trustees and the remaining Trustee shall be elected by Common Shareholders and the Preferred Shareholders, voting together as a single class. The holders of preferred shares will be entitled to elect a majority of the Fund's Trustees under certain circumstances.

Compensation

Messrs. Connor and Dalessandro also serve as Trustees of PIMCO Municipal Income Fund, PIMCO California Municipal Income Fund, PIMCO New York Municipal Income Fund, PIMCO Municipal Income Fund II, PIMCO California Municipal Income Fund II, PIMCO New York Municipal Income Fund II, PIMCO Municipal Income Fund III, PIMCO California Municipal Income Fund III and PIMCO New York Municipal Income Fund III (together, the "Municipal Funds"), Nicholas-Applegate Convertible & Income Fund, PIMCO Corporate Opportunity Fund and PIMCO Corporate Income Fund, twelve closed-end funds for which the Manager serves as investment manager and PIMCO or Nicholas-Applegate Capital Management LLC, each an affiliate of the Manager, serves as portfolio manager. Mr. Kertess also serves as Trustee of PIMCO Municipal Income Fund, PIMCO California Municipal Income Fund, PIMCO New York Municipal Income Fund, PIMCO Municipal Income Fund II, PIMCO California Municipal Income Fund II, PIMCO New York Municipal Income Fund II and PIMCO Corporate Income Fund. In addition to the Fund, the Municipal Funds, Nicholas-Applegate Convertible & Income Fund, PIMCO Corporate Opportunity Fund, and PIMCO Corporate Income Fund, Mr. Connor is a director or trustee, as the case may be, of one open-end investment company (comprising two separate investment

-54-

portfolios) and one closed-end investment company advised by the Manager. As indicated above, certain of the officers and Trustees of the Fund are affiliated with the Manager and/or PIMCO.

The Municipal Funds, Nicholas-Applegate Convertible & Income Fund, PIMCO Corporate Opportunity Fund, PIMCO Corporate Income Fund and the Fund (together, the "PIMCO Closed-End Funds") are expected to hold joint meetings of their Boards of Trustees whenever possible. Each Trustee, other than any Trustee who is a director, officer, partner or employee of the Manager, PIMCO or any entity controlling, controlled by or under common control with the Manager or PIMCO, receives $24,000 for each joint meeting for the first four joint meetings in each year and $12,000 for each additional joint meeting in such year if the meetings are attended in person. Trustees receive $6,000 per joint meeting if the meetings are attended telephonically. Members of the Audit Oversight Committee will receive $500 per joint meeting of the PIMCO Closed-End Funds' Audit Oversight Committees if the meeting takes place on a day other than the day of a regularly scheduled Board meeting. Trustees will also be reimbursed for meeting-related expenses.

The PIMCO Closed-End Funds will allocate the Trustees' compensation and other costs of their joint meetings pro rata based on each PIMCO Closed-End Fund's net assets, including assets attributable to any Preferred Shares.

It is estimated that the Trustees will receive the amounts set forth in the following table from the Fund for its initial fiscal year ending March 31, 2004. For the calendar year ended December 31, 2002, the Trustees received the compensation set forth in the following table for serving as trustees of other funds in the "Fund Complex." Each officer and Trustee who is a director, officer, partner or employee of the Manager, PIMCO or any entity controlling, controlled by or under common control with the Manager or PIMCO serves without any compensation from the Fund.

* Since the Fund has not completed its first full fiscal year, compensation is estimated based upon future payments to be made by the Fund during the current fiscal year and upon estimated relative net assets of the PIMCO Closed-End Funds.

** In addition to the PIMCO Closed-End Funds, during the year ended December 31, 2002, Mr. Connor served as a director or trustee of one open-end investment company (comprising two separate investment portfolios) and one closed-end investment company advised by the Manager. These investment companies are considered to be in the same "Fund Complex" as the Fund.

The Fund has no employees. Its officers are compensated by the Manager and/or PIMCO.

Codes of Ethics

The Fund, the Manager and PIMCO have each adopted a separate code of ethics governing personal trading activities of, as applicable, all Trustees and officers of the Fund, and directors, officers and employees of the Manager and PIMCO, who, in connection with their regular functions, play a role in the recommendation of any purchase or sale of a security by the Fund or obtain information pertaining to such purchase or sale or who have the power to influence the management or policies of the Fund, the Manager or PIMCO, as applicable. Such persons are prohibited from effecting certain transactions, allowed to effect certain exempt transactions (including with respect to securities that may be purchased or held by the Fund), and are required to preclear certain security transactions with the applicable compliance officer or his designee and to report certain transactions on a regular basis. The Fund, the Manager and PIMCO have each developed procedures for administration of their respective codes. Text-only versions of the codes of ethics can be viewed online or downloaded from the EDGAR Database on the SEC's internet web site at www.sec.gov. You may also review and copy those documents by visiting the SEC's Public Reference Room in Washington, DC. Information on the operation of the Public Reference Room may be obtained by calling the SEC at 202-942-8090. In addition, copies of the codes of ethics may be obtained, after mailing the appropriate duplicating fee, by writing to the SEC's Public Reference Section, 450 5th Street, N.W., Washington, DC 20549-0102 or by e-mail request at publicinfo@sec.gov.

INVESTMENT MANAGER AND PORTFOLIO MANAGER

Investment Manager

The Manager serves as investment manager to the Fund pursuant to an investment management agreement (the "Investment Management Agreement") between it and the Fund. The Manager, a Delaware limited liability company organized in 2000, is wholly-owned by PIMCO Advisors Retail Holdings LLC, a wholly-owned subsidiary of Allianz Dresdner Asset Management of America L.P. ("ADAM of America," formerly PIMCO Advisors L.P.). ADAM of America was organized as a limited partnership under Delaware law in 1987. ADAM of America's sole general partner is Allianz-Paclife Partners LLC. Allianz-Paclife Partners LLC is a Delaware limited liability company with three members, ADAM U.S. Holding LLC, a Delaware limited liability company, Pacific Asset Management LLC, a Delaware limited liability company, and Pacific Life Insurance Company ("Pacific Life"), a California stock life insurance company. Pacific Asset Management LLC is a wholly-owned subsidiary of Pacific

-56-

Life, which is a wholly-owned subsidiary of Pacific Mutual Holding Company. Pacific Life owns an indirect minority equity interest in ADAM of America. The sole member of ADAM U.S. Holding LLC is Allianz Dresdner Asset Management of America LLC. Allianz Dresdner Asset Management of America LLC has two members, Allianz of America, Inc. ("Allianz of America"), a Delaware corporation which owns a 99.9% non-managing interest, and Allianz Dresdner Asset Management of America Holding Inc., a Delaware corporation which owns a 0.01% managing interest. Allianz of America is a wholly-owned subsidiary of Allianz Aktiengesellschaft ("Allianz AG"). Allianz Dresdner Asset Management of America Holding Inc. is a wholly-owned subsidiary of ADAM GmbH, which is a wholly-owned subsidiary of Allianz AG. Allianz AG indirectly holds a controlling interest in ADAM of America. Allianz AG is a European-based, multinational insurance and financial services holding company. Allianz AG's address is Koeniginstrasse 28, D-80802, Munich, Germany. Pacific Life's address is 700 Newport Center Drive, Newport Beach, California 92660. ADAM of America's address is 888 San Clemente Drive, Suite 100, Newport Beach, California 92660.

The general partner of ADAM of America has substantially delegated its management and control of ADAM of America to an Executive Committee. The Executive Committee of ADAM of America is comprised of William S. Thompson, Jr. and David C. Flattum.

The Manager is located at 1345 Avenue of the Americas, New York, New York 10105. As of March 31, 2003, the Manager had approximately $17.7 billion in assets under management. As of March 31, 2003, ADAM of America and its subsidiary partnerships had approximately $390 billion in assets under management.

Allianz of America has entered into a put/call arrangement for the possible disposition of Pacific Life's indirect interest in ADAM of America. The put option held by Pacific Life will allow it to require Allianz of America, on the last business day of each calendar quarter following May 5, 2000, to purchase at a formula-based price all ADAM of America's units owned directly or indirectly by Pacific Life. The call option held by Allianz of America will allow it, beginning January 31, 2003 or upon a change in control of Pacific Life, to require Pacific Life to sell or cause to be sold to Allianz of America, at the same formula-based price, all of ADAM of America's units owned directly or indirectly by Pacific Life.

As of the date of this Statement of Additional Information, significant institutional shareholders of Allianz AG currently include Munchener Ruckversicherungs-Gesellschaft AG ("Munich Re") and HypoVereinsbank. Allianz AG in turn owns more than 95% of Dresdner Bank AG. Credit Lyonnais, Munich Re and HypoVereinsbank, as well as certain broker-dealers that might be controlled by or affiliated with these entities or Dresdner Bank AG, such as Dresdner Klienwort Wasserstein, Dresdner Kleinwort Benson and Grantchester Securities, Inc., may be considered to be affiliated persons of the Manager and PIMCO. (Broker-dealer affiliates of such significant institutional shareholders are sometimes referred to herein as "Affiliated Brokers.") Absent an SEC exemption or other relief, the Fund generally is precluded from effecting principal transactions with the Affiliated Brokers, and its ability to purchase securities being underwritten by an Affiliated Broker or a syndicate including an Affiliated Broker is subject to restrictions. Similarly, the Fund's ability to utilize the Affiliated Brokers for agency transactions is subject to the restrictions of Rule 17e-1 under the 1940 Act. PIMCO does not believe that the restrictions on transactions with the Affiliated Brokers described above will

-57-

materially adversely affect its ability to provide services to the Fund, the Fund's ability to take advantage of market opportunities, or the Fund's overall performance.

The Manager, subject to the supervision of the Board of Trustees, is responsible for managing, either directly or through others selected by the Manager, the investments of the Fund. The Manager also furnishes to the Board of Trustees periodic reports on the investment performance of the Fund. As more fully discussed below, the Manager has retained PIMCO to serve as the Fund's portfolio manager.

Under the terms of the Investment Management Agreement, subject to such policies as the Trustees may determine, the Manager, at its expense, furnishes continuously an investment program for the Fund and makes investment decisions on behalf of the Fund and places all orders for the purchase and sale of portfolio securities subject always to the Fund's investment objectives, policies and restrictions; provided that, so long as PIMCO serves as the portfolio manager for the Fund, the Manager's obligation under the Investment Management Agreement with respect to the Fund is, subject always to the control of the Trustees, to determine and review with PIMCO the investment policies of the Fund.

Subject to the control of the Trustees, the Manager also manages, supervises and conducts the other affairs and business of the Fund, furnishes office space and equipment, provides bookkeeping and certain clerical services (excluding determination of the net asset value of the Fund, shareholder accounting services and the accounting services for the Fund) and pays all salaries, fees and expenses of officers and Trustees of the Fund who are affiliated with the Manager. As indicated under "Portfolio Transactions--Brokerage and Research Services," the Fund's portfolio transactions may be placed with broker-dealers which furnish the Manager and PIMCO, without cost, certain research, statistical and quotation services of value to them or their respective affiliates in advising the Fund or their other clients. In so doing, the Fund may incur greater brokerage commissions and other transactions costs than it might otherwise pay.

Pursuant to the Investment Management Agreement, the Fund has agreed to pay the Manager an annual management fee, payable on a monthly basis, at the annual rate of 0.70% of the Fund's average daily net assets (including net assets attributable to Preferred Shares) for the services and facilities it provides. All fees and expenses are accrued daily and deducted before payment of dividends to investors.

Except as otherwise described in the Prospectus, the Fund pays, in addition to the investment management fee described above, all expenses not assumed by the Manager, including, without limitation, fees and expenses of Trustees who are not "interested persons" of the Manager or the Fund, interest charges, taxes, brokerage commissions, expenses of issue of shares, fees and expenses of registering and qualifying the Fund and its classes of shares for distribution under federal and state laws and regulations, charges of custodians, auditing and legal expenses, expenses of determining net asset value of the Fund, reports to shareholders, expenses of meetings of shareholders, expenses of printing and mailing prospectuses, proxy statements and proxies to existing shareholders, and its proportionate share of insurance premiums and professional association dues or assessments. The Fund is also responsible for such nonrecurring expenses as may arise, including litigation in which the Fund may be a party,

-58-

and other expenses as determined by the Trustees. The Fund may have an obligation to indemnify its officers and Trustees with respect to such litigation

Portfolio Manager

PIMCO serves as portfolio manager for the Fund pursuant to a portfolio management agreement (the "Portfolio Management Agreement") between PIMCO and the Manager. Under the Portfolio Management Agreement, subject always to the control of the Trustees and the supervision of the Manager, PIMCO's obligation is to furnish continuously an investment program for the Fund, to make investment decisions on behalf of the Fund and to place all orders for the purchase and sale of portfolio securities and all other investments for the Fund.

Under the Portfolio Management Agreement, the Manager (and not the Fund) pays a portion of the fees it receives from the Fund to PIMCO in return for PIMCO's services, at the annual rate of 0.3575% of the Fund's average daily net assets (including assets attributable to any Preferred Shares that may be outstanding) for the period from the commencement of Fund operations through April 30, 2008 (i.e., roughly the first five years of Fund operations) (the "Initial Period") and at the rate of 0.50% of such average daily net assets thereafter while the Investment Management Agreement remains in effect (the "Remaining Period").

Originally organized in 1971, reorganized as a Delaware general partnership in 1994 and reorganized as a Delaware limited liability company in 2000, PIMCO provides investment management and advisory services to private accounts of institutional and individual clients and to mutual funds. The membership interests of PIMCO as of December 1, 2002, were held 91% by ADAM of America and 9% by the managing directors of PIMCO. As of March 31, 2003, PIMCO had approximately $323 billion in assets under management. PIMCO is located at 840 Newport Center Drive, Newport Beach, California 92660.

Certain Terms of the Investment Management and Portfolio Management Agreements

The Investment Management Agreement and the Portfolio Management Agreement were each approved by the Trustees of the Fund (including all of the Trustees who are not "interested persons" of the Manager or PIMCO). The Investment Management Agreement and Portfolio Management Agreement will each continue in force with respect to the Fund for two years from their respective dates, and from year to year thereafter, but only so long as their continuance is approved at least annually by (i) vote, cast in person at a meeting called for that purpose, of a majority of those Trustees who are not "interested persons" of the Manager, PIMCO or the Fund, and (ii) the majority vote of either the full Board of Trustees or the vote of a majority of the outstanding shares of all classes of the Fund. Each of the Investment Management Agreement and Portfolio Management Agreement automatically terminates on assignment. The Investment Management Agreement may be terminated on not less than 60 days' notice by the Manager to the Fund or by the Fund to the Manager. The Portfolio Management Agreement may be terminated on not less than 60 days' notice by the Manager to PIMCO or by PIMCO to the Manager, or by the Fund at any time by notice to the Manager and PIMCO.

The Investment Management Agreement and the Portfolio Management Agreement each provide that the Manager or PIMCO, as applicable, shall not be subject to any liability in

-59-

connection with the performance of its services thereunder in the absence of willful misfeasance, bad faith, gross negligence or reckless disregard of its obligations and duties.

Basis for Approval of the Investment Management and Portfolio Management Agreements

In determining to approve the Investment Management Agreement and the Portfolio Management Agreement, the Trustees met with the relevant investment advisory personnel from the Manager and PIMCO and considered information relating to the education, experience and number of investment professionals and other personnel who would provide services under the applicable agreement. See "Management of the Fund" in the Prospectus and this Statement of Additional Information. The Trustees also took into account the time and attention to be devoted by senior management to the Fund and the other funds in the complex. The Trustees evaluated the level of skill required to manage the Fund and concluded that the human resources to be available at the Manager and PIMCO were appropriate to fulfill effectively the duties of the Manager and PIMCO on behalf of the Fund under the applicable agreement. The Trustees also considered the business reputation of the Manager and PIMCO, their financial resources and professional liability insurance coverage and concluded that they would be able to meet any reasonably foreseeable obligations under the applicable agreement.

The Trustees received information concerning the investment philosophy and investment process to be applied by PIMCO in managing the Fund. In this connection, the Trustees considered PIMCO's in-house research capabilities as well as other resources available to PIMCO's personnel, including research services available to PIMCO as a result of securities transactions effected for the Fund and other investment advisory clients. The Trustees concluded that PIMCO's investment process, research capabilities and philosophy were well suited to the Fund, given the Fund's investment objectives and policies.

The Trustees considered the scope of the services provided by the Manager and PIMCO to the Fund under the Investment Management Agreement and Portfolio Management Agreement, respectively, relative to services provided by third parties to other mutual funds. The Trustees noted that the Manager's and PIMCO's standard of care was comparable to that found in most investment company advisory agreements. See "--Certain Terms of the Investment Management and Portfolio Management Agreements" above. The Trustees concluded that the scope of the Manager's and PIMCO's services to be provided to the Fund was consistent with the Fund's operational requirements, including, in addition to its investment objectives, compliance with the Fund's investment restrictions, tax and reporting requirements and related shareholder services.

The Trustees considered the quality of the services to be provided by the Manager and PIMCO to the Fund. The Trustees also evaluated the procedures of the Manager and PIMCO designed to fulfill the their fiduciary duty to the Fund with respect to possible conflicts of interest, including their codes of ethics (regulating the personal trading of their officers and employees) (see "Management of the Fund--Code of Ethics" above), the procedures by which PIMCO allocates trades among its various investment advisory clients, the integrity of the systems in place to ensure compliance with the foregoing and the record of PIMCO in these matters. The Trustees also received information concerning standards of the Manager and

-60-

PIMCO with respect to the execution of portfolio transactions. See "Portfolio Transactions" below.

In approving the agreements, the Trustees also gave substantial consideration to the fees payable under the agreements. The Trustees reviewed information concerning fees paid to investment advisers of similar bond funds. The Trustees also considered the fees of the Fund as a percentage of assets at different asset levels and possible economies of scale to the Manager. The Trustees evaluated the Manager's profitability with respect to the Fund, concluding that such profitability was not inconsistent with levels of profitability that had been determined by courts not to be "excessive." In evaluating the Fund's advisory fees, the Trustees also took into account the complexity of investment management for the Fund relative to other types of funds.

PORTFOLIO TRANSACTIONS

Investment Decisions and Portfolio Transactions

Investment decisions for the Fund and for the other investment advisory clients of the Manager and PIMCO are made with a view to achieving their respective investment objectives. Investment decisions are the product of many factors in addition to basic suitability for the particular client involved (including the Fund). Some securities considered for investments by the Fund may also be appropriate for other clients served by the Manager and PIMCO. Thus, a particular security may be bought or sold for certain clients even though it could have been bought or sold for other clients at the same time. If a purchase or sale of securities consistent with the investment policies of the Fund and one or more of these clients served by the Manager or PIMCO is considered at or about the same time, transactions in such securities will be allocated among the Fund and clients in a manner deemed fair and reasonable by the Manager or PIMCO, as applicable. The Manager or PIMCO may aggregate orders for the Fund with simultaneous transactions entered into on behalf of its other clients so long as price and transaction expenses are averaged either for that transaction or for the day. Likewise, a particular security may be bought for one or more clients when one or more clients are selling the security. In some instances, one client may sell a particular security to another client. It also sometimes happens that two or more clients simultaneously purchase or sell the same security, in which event each day's transactions in such security are, insofar as possible, averaged as to price and allocated between such clients in a manner which the Manager or PIMCO believes is equitable to each and in accordance with the amount being purchased or sold by each. There may be circumstances when purchases or sales of portfolio securities for one or more clients will have an adverse effect on other clients.

Brokerage and Research Services

There is generally no stated commission in the case of debt securities, which are 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. Transactions on U.S. stock exchanges and other agency transactions involve the payment by the Fund of negotiated brokerage commissions. Such commissions vary among different brokers. Also, a

-61-

particular broker may charge different commissions according to such factors as the difficulty and size of the transaction.

Subject to the supervision of the Manager, PIMCO places all orders for the purchase and sale of portfolio securities, options, futures contracts and other instruments for the Fund and buys and sells such securities, options, futures contracts and other instruments for the Fund through a substantial number of brokers and dealers. In so doing, PIMCO uses its best efforts to obtain for the Fund the most favorable price and execution available, except to the extent it may be permitted to pay higher brokerage commissions as described below. In seeking the most favorable price and execution, PIMCO, having in mind the Fund's best interests, considers all factors it deems relevant, including, by way of illustration, price, the size of the transaction, the nature of the market for the security, the amount of the commission, the timing of the transaction taking into account market prices and trends, the reputation, experience and financial stability of the broker-dealer involved and the quality of service rendered by the broker-dealer in other transactions.

Subject to the supervision of the Manager, PIMCO places orders for the purchase and sale of portfolio investments for the Fund's account with brokers or dealers selected by it in its discretion. In effecting purchases and sales of portfolio securities for the account of the Fund, PIMCO will seek the best price and execution of the Fund's orders. In doing so, the Fund may pay higher commission rates than the lowest available when PIMCO believes it is reasonable to do so in light of the value of the brokerage and research services provided by the broker effecting the transaction, as discussed below.

It has for many years been a common practice in the investment advisory business for advisers of investment companies and other institutional investors to receive research services from broker-dealers which execute portfolio transactions for the clients of such advisers. Consistent with this practice, PIMCO may receive research services from many broker-dealers with which PIMCO places the Fund's portfolio transactions. PIMCO may also receive research or research credits from brokers which are generated from underwriting commissions when purchasing new issues of debt securities or other assets for the Fund. These services, which in some cases may also be purchased for cash, include such matters as general economic and security market reviews, industry and company reviews, evaluations of securities and recommendations as to the purchase and sale of securities. Some of these services are of value to PIMCO in advising various of its clients (including the Fund), although not all of these services are necessarily useful and of value in managing the Fund. Neither the management fee paid by the Fund to the Manager nor the portfolio management fee paid by the Manager to PIMCO is reduced because PIMCO and its affiliates receive such services.

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

-62-

The Fund may use broker-dealers that are affiliates (or affiliates of affiliates) of the Fund, the Manager and/or PIMCO, subject to certain restrictions discussed above under "Investment Manager and Portfolio Manager--Investment Manager."

References to PIMCO in this section would apply equally to the Manager if the Manager were to assume portfolio management responsibilities for the Fund and place orders for the purchase and sale of the Fund's portfolio investments.

DISTRIBUTIONS

See "Description of Preferred Shares--Dividends" and "Description of Capital Structure" in the prospectus for information relating to distributions to Fund shareholders.

For tax purposes, the Fund is currently required to allocate net capital gain and other taxable income, if any, among Common Shares, the Series M Preferred Shares, the Series T Preferred Shares, the Series W Preferred Shares, the Series TH Preferred Shares and the Series F Preferred Shares in proportion to total dividends paid to each class for the year in which such net capital gain or other taxable income is realized.

While any Preferred Shares are outstanding, the Fund may not declare any cash dividend or other distribution on its Common Shares unless at the time of such declaration (1) all accumulated dividends on the Preferred Shares have been paid and (2) the net asset value of the Fund's portfolio (determined after deducting the amount of such dividend or other distribution) is at least 200% of the liquidation value of any outstanding Preferred Shares. This latter limitation on the Fund's ability to make distributions on its Common Shares could cause the Fund to incur income and excise tax and, under certain circumstances, impair the ability of the Fund to maintain its qualification for taxation as a regulated investment company. See "Tax Matters."

The Board of Trustees has declared a dividend of $0.121875 per Common Share payable on July 1, 2003.

DESCRIPTION OF SHARES

Common Shares

The Fund's Declaration authorizes the issuance of an unlimited number of Common Shares. The Common Shares currently outstanding have been issued with a par value of $0.00001 per share. All Common Shares of the Fund have equal rights as to the payment of dividends and the distribution of assets upon liquidation of the Fund. The Common Shares currently outstanding have been fully paid and, subject to matters discussed in "Anti-Takeover and Other Provisions in the Declaration of Trust--Shareholder Liability" below, are non-assessable, and have no pre-emptive or conversion rights or rights to cumulative voting. At any time when the Fund's Preferred Shares are outstanding, Common Shareholders will not be entitled to receive any distributions from the Fund unless all accrued dividends on Preferred Shares have been paid, and unless asset coverage (as defined in the 1940 Act) with respect to Preferred Shares would be at least 200% after giving effect to such distributions. See "--

-63-

Preferred Shares" below. See "Description of Preferred Shares--Dividends--Restrictions on Dividends and Other Payments" and "Description of Capital Structure" in the prospectus.

The Common Shares are listed on the New York Stock Exchange. The Fund intends to hold annual meetings of shareholders so long as the Common Shares are listed on a national securities exchange and such meetings are required as a condition to such listing.

Shares of closed-end investment companies may frequently trade at prices lower than net asset value. Shares of closed-end investment companies like the Fund that invest predominantly in below investment-grade debt obligations have during some periods traded at prices higher than net asset value and during other periods traded at prices lower than net asset value. There can be no assurance that Common Shares or shares of other similar funds will trade at a price higher than net asset value in the future. Net asset value will be reduced immediately following any offering of Preferred Shares by the costs of that offering paid by the Fund. Net asset value generally increases when interest rates decline, and decreases when interest rates rise, and these changes are likely to be greater in the case of a fund, such as the Fund, having a leveraged capital structure. Whether investors realize gains or losses upon the sale of Common Shares does not depend upon the Fund's net asset value but depends entirely upon whether the market price of the Common Shares at the time of sale is above or below the original purchase price for the shares. Since the market price of the Fund's Common Shares will be determined by factors beyond the control of the Fund, the Fund cannot predict whether the Common Shares will trade at, below, or above net asset value or at, below or above the initial public offering price. Accordingly, the Common Shares are designed primarily for long-term investors, and investors in the Common Shares should not view the Fund as a vehicle for trading purposes. See "Repurchase of Common Shares; Conversion to Open End Fund."

ANTI-TAKEOVER AND OTHER PROVISIONS IN THE DECLARATION OF TRUST

Shareholder Liability

Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Fund. However, the Declaration contains an express disclaimer of shareholder liability for acts or obligations of the Fund and requires that notice of such disclaimer be given in each agreement, obligation or instrument entered into or executed by the Fund or the Trustees. The Declaration also provides for indemnification out of the Fund's property for all loss and expense of any shareholder held personally liable on account of being or having been a shareholder. Thus, the risk of a shareholder incurring financial loss on account of shareholder liability is limited to circumstances in which such disclaimer is inoperative or the Fund is unable to meet its obligations, and thus should be considered remote.

-64-

Anti-Takeover Provisions

As described below, the Declaration 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 opportunities to sell their shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund.

The Fund's Trustees are divided into three classes (Class I, Class II and Class III), having initial terms of one, two and three years, respectively. At each annual meeting of shareholders, the term of one class will expire and each Trustee elected to that class will hold office for a term of three years. The classification of the Board of Trustees in this manner could delay for an additional year the replacement of a majority of the Board of Trustees. In addition, the Declaration provides that a Trustee may be removed only for cause and only (i) by action of at least seventy-five percent (75%) of the outstanding shares of the classes or series of shares entitled to vote for the election of such Trustee, or (ii) by at least seventy-five percent (75%) of the remaining Trustees.

Except as provided in the next paragraph, the affirmative vote or consent of at least seventy-five percent (75%) of the Board of Trustees and at least seventy-five percent (75%) of the shares of the Fund outstanding and entitled to vote thereon are required to authorize any of the following transactions (each a "Material Transaction"): (1) a merger, consolidation or share exchange of the Fund or any series or class of shares of the Fund with or into any other person or company, or of any such person or company with or into the Fund or any such series or class of shares; (2) the issuance or transfer by the Fund or any series or class of shares (in one or a series of transactions in any twelve-month period) of any securities of the Fund or such series or class to any other person or entity for cash, securities or other property (or combination thereof) having an aggregate fair market value of $1,000,000 or more, excluding sales of securities of the Fund or such series or class in connection with a public offering, issuances of securities of the Fund or such series or class pursuant to a dividend reinvestment plan adopted by the Fund and issuances of securities of the Fund or such series or class upon the exercise of any stock subscription rights distributed by the Fund; or (3) a sale, lease, exchange, mortgage, pledge, transfer or other disposition by the Fund or any series or class of shares (in one or a series of transactions in any twelve-month period) to or with any person of any assets of the Fund or such series or class having an aggregate fair market value of $1,000,000 or more, except for transactions in securities effected by the Fund or such series or class in the ordinary course of its business. The same affirmative votes are required with respect to any shareholder proposal as to specific investment decisions made or to be made with respect to the Fund's assets or the assets of any series or class of shares of the Fund.

Notwithstanding the approval requirements specified in the preceding paragraph, the Declaration requires no vote or consent of the Fund's shareholders to authorize a Material Transaction if the transaction is approved by a vote of both a majority of the Board of Trustees and seventy-five percent (75%) of the Continuing Trustees (as defined below), so long as all other conditions and requirements, if any, provided for in the Fund's Bylaws and applicable law (including any shareholder voting rights under the 1940 Act) have been satisfied.

-65-

In addition, the Declaration provides that the Fund may be terminated at any time by vote or consent of at least seventy-five percent (75%) of the Fund's shares or, alternatively, by vote or consent of both a majority of the Board of Trustees and seventy-five percent (75%) of the Continuing Trustees (as defined below).

In certain circumstances, the Declaration also imposes shareholder voting requirements that are more demanding than those required under the 1940 Act in order to authorize a conversion of the Fund from a closed-end to an open-end investment company. See "Repurchase of Common Shares; Conversion to Open-End Fund" below.

As noted, the voting provisions described above could have the effect of depriving Common Shareholders of an opportunity to sell their Common Shares at a premium over prevailing market prices by discouraging a third party from seeking to obtain control of the Fund in a tender offer or similar transaction. In the view of the Fund's Board of Trustees, however, these provisions offer several possible advantages, including: (1) requiring persons seeking control of the Fund to negotiate with its management regarding the price to be paid for the amount of Common Shares required to obtain control; (2) promoting continuity and stability; and (3) enhancing the Fund's ability to pursue long-term strategies that are consistent with its investment objectives and management policies. The Board of Trustees has determined that the voting requirements described above, which are generally greater than the minimum requirements under the 1940 Act, are in the best interests of the Fund's Common Shareholders generally.

A "Continuing Trustee," as used in the discussion above, is any member of the Fund's Board of Trustees who either (i) has been a member of the Board for a period of at least thirty-six months (or since the commencement of the Fund's operations, if less than thirty-six months) or (ii) was nominated to serve as a member of the Board of Trustees by a majority of the Continuing Trustees then members of the Board.

The foregoing is intended only as a summary and is qualified in its entirety by reference to the full text of the Declaration and the Fund's Bylaws, both of which have been filed as exhibits to the Fund's registration statement on file with the SEC.

Liability of Trustees

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

REPURCHASE OF COMMON SHARES; CONVERSION TO OPEN-END FUND

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, price, dividend

-66-

stability, relative demand for and supply of such shares in the market, general market and economic conditions and other factors. Shares of a closed-end investment company may frequently trade at prices lower than net asset value. The Fund's Board of Trustees regularly monitors the relationship between the market price and net asset value of the Common Shares. If the Common Shares were to trade at a substantial discount to net asset value for an extended period of time, the Board may consider the repurchase of its Common Shares on the open market or in private transactions, or the making of a tender offer for such shares. There can be no assurance, however, that the Board of Trustees will decide to take or propose any of these actions, or that share repurchases or tender offers, if undertaken, will reduce market discount. The Fund has no present intention to repurchase its Common Shares and would do so only in the circumstances described in this section.

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 accrued dividends on Preferred Shares have been paid and (2) at the time of such purchase, redemption or acquisition, the net asset value of the Fund's portfolio (determined after deducting the acquisition price of the Common Shares) is at least 200% of the liquidation value of the outstanding Preferred Shares (expected to equal the original purchase price per share plus any accrued and unpaid dividends thereon).

Subject to its investment limitations, 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 Board of Trustees would have to comply with the Securities Exchange Act of 1934, as amended, and the 1940 Act and the rules and regulations thereunder.

The Fund's Board of Trustees may also from time to time consider submitting to the holders of the shares of beneficial interest of the Fund a proposal to convert the Fund to an open-end investment company. In determining whether to exercise its sole discretion to submit this issue to shareholders, the Board of Trustees would consider all factors then relevant, including the relationship of the market price of the Common Shares to net asset value, the extent to which the Fund's capital structure is leveraged and the possibility of re-leveraging, the spread, if any, between the yields on securities in the Fund's portfolio and interest and dividend charges on Preferred Shares issued by the Fund and general market and economic conditions.

The Declaration requires the affirmative vote or consent of holders of at least seventy-five percent (75%) of each class of the Fund's shares entitled to vote on the matter to authorize a conversion of the Fund from a closed-end to an open-end investment company, unless the conversion is authorized by both a majority of the Board of Trustees and seventy-five percent (75%) of the Continuing Trustees (as defined above under "Anti-Takeover and Other Provisions in the Declaration of Trust--Anti-Takeover Provisions"). This seventy-five percent (75%) shareholder approval requirement is higher than is required under the 1940 Act. In the event that a conversion is approved by the Trustees and the Continuing Trustees as described above, the minimum shareholder vote required under the 1940 Act would be necessary to authorize the conversion. Currently, the 1940 Act would require approval of the holders of a "majority of the outstanding" Common Shares and, if issued, Preferred Shares voting together as a single class,

-67-

and the holders of a "majority of the outstanding" Preferred Shares voting as a separate class, in order to authorize a conversion.

If the Fund converted to an open-end company, it would be required to redeem all Preferred Shares then outstanding (requiring in turn that it liquidate a portion of its investment portfolio), and the Fund's Common Shares likely would no longer be listed on the New York Stock Exchange. Shareholders of an open-end investment company may require the company to redeem their shares on any business day (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 redemption. In order to avoid maintaining large cash positions or liquidating favorable investments to meet redemptions, open-end companies typically engage in a continuous offering of their shares. Open-end companies are thus subject to periodic asset in-flows and out-flows that can complicate portfolio management.

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 tenders 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 at net asset value from time to time, or that the Fund may be converted to an open-end 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 assets. This 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. See the Prospectus under "Risks--Leverage Risk."

Before deciding whether to take any action if the Fund's Common Shares trade below net asset value, the Board of Trustees would consider all relevant factors, including the extent and duration of the discount, the liquidity of the Fund's portfolio, the impact of any action that might be taken on the Fund or its shareholders and market considerations. Based on these considerations, even if the Fund's shares should trade at a discount, the Board of Trustees may determine that, in the interest of the Fund and its shareholders, no action should be taken.

TAX MATTERS

Taxation of the Fund. The Fund intends to qualify each year as a regulated investment company under Subchapter M of the Code. In order to qualify for the special tax treatment accorded regulated investment companies and their shareholders, the Fund must, among other things:

(a) derive at least 90% of its gross income from dividends, interest, payments with respect to certain securities loans, and gains from the sale of stock, securities or foreign currencies, or other income (including but not limited to gains from options, futures, or forward contracts) derived with respect to its business of investing in such stock, securities, or currencies;

-68-

(b) distribute with respect to each taxable year at least 90% of the sum of its investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid--generally taxable ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and net tax-exempt interest income, for such year; and

(c) diversify its holdings so that, at the end of each quarter of the Fund's 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 limited in respect of any one issuer to a value not greater than 5% of the value of the Fund's total assets and not more than 10% of the outstanding voting securities of such issuer, and (ii) not more than 25% of the value of the Fund's total assets is invested in the securities (other than those of the U.S. Government or other regulated investment companies) of any one issuer or of two or more issuers which the Fund controls and which are engaged in the same, similar, or related trades or businesses.

If the Fund qualifies as a regulated investment company that is accorded special tax treatment, the Fund will not be subject to federal income tax on income distributed in a timely manner to its shareholders in the form of dividends (including Capital Gain Dividends, as defined below).

If the Fund failed to qualify as a regulated investment company accorded special tax treatment in any taxable year, the Fund would be subject to tax on its taxable income at corporate rates, and all distributions from earnings and profits, including any distributions of net tax-exempt income and net long-term capital gains, generally would be taxable to shareholders as ordinary income. Such distributions generally would be eligible (i) to be treated as qualified dividend income in the case of shareholders taxed as individuals, and (ii) for the dividends received deduction in the case of corporate shareholders. In addition, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest and make substantial distributions before requalifying as a regulated investment company that is accorded special tax treatment.

The Fund intends to distribute at least annually to its shareholders all or substantially all of its investment company taxable income and any net tax-exempt interest, and may distribute its net capital gain. The Fund may also retain for investment its net capital gain. If the Fund does retain any net capital gain or any investment company taxable income, it will be subject to tax at regular corporate rates on the amount retained. If the Fund retains any net capital gain, it may designate the retained amount as undistributed capital gains in a notice to its shareholders who, if subject to federal income tax on long-term capital gains, (i) will be required to include in income for federal income tax purposes, as long-term capital gain, their shares of such undistributed amount, and (ii) will be entitled to credit their proportionate shares of the tax paid by the Fund on such undistributed amount against their federal income tax liabilities, if any, and to claim refunds to the extent the credit exceeds such liabilities. For federal income tax purposes, the tax basis of shares owned by a shareholder of the Fund will be increased by an amount equal under current law to the difference between the amount of undistributed capital gains included in the shareholder's gross income and the tax deemed paid by the shareholder under clause (ii) of the preceding sentence.

-69-

Treasury regulations permit a regulated investment company, in determining its investment company taxable income and net capital gain, to elect to treat all or part of any net capital loss, any net long-term capital loss or any net foreign currency loss incurred after October 31 as if it had been incurred in the succeeding year.

If the Fund fails to distribute in a calendar year at least an amount equal to the sum of 98% of its ordinary income for such year and 98% of its capital gain net income for the one-year period ending October 31 of such year, plus any retained amount from the prior year, the Fund will be subject to a nondeductible 4% excise tax on the undistributed amounts. For these purposes, the Fund will be treated as having distributed any amount for which it is subject to income tax. A dividend paid to shareholders in January of a year generally is deemed to have been paid by the Fund on December 31 of the preceding year, if the dividend was declared and payable to shareholders of record on a date in October, November or December of that preceding year. The Fund intends generally to make distributions sufficient to avoid imposition of the 4% excise tax.

Fund Distributions. Distributions from the Fund generally will be taxable to shareholders as ordinary income to the extent derived from investment income and net short-term capital gains. Distributions of net capital gains (that is, the excess of net gains from the sale of capital assets held more than one year over net losses from the sale of capital assets held for not more than one year) properly designated as capital gain dividends ("Capital Gain Dividends") will be taxable to shareholders as long-term capital gain, regardless of how long a shareholder has held the shares in the Fund. Long-term capital gain rates applicable to individuals have been temporarily reduced--in general, to 15% with lower rates applying to taxpayers in the 10% and 15% rate brackets--for taxable years beginning on or before December 31, 2008.

For taxable years beginning on or before December 31, 2008, provided holding period and other requirements are met, the Fund may designate distributions of investment income derived from dividends of U.S. corporations and some foreign corporations as "qualified dividend income." Qualified dividend income will be taxed in the hands of individuals at the rates applicable to long-term capital gain, provided these same holding period and other requirements are met by the shareholder. The Fund does not expect a significant portion of Fund distributions to be derived from qualified dividend income.

-70-

Dividends of net investment income received by corporate shareholders of the Fund will qualify for the 70% dividends received deduction generally available to corporations to the extent of the amount of qualifying dividends received by the Fund from domestic corporations for the taxable year. It is not expected that any significant percentage of the Fund's distributions will so qualify.

The Internal Revenue Service 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) based upon the percentage of total dividends distributed to each class for the tax year. Accordingly, the Fund intends each year to allocate Capital Gain Dividends between and among its Common Shares, Series M Preferred Shares, Series T Preferred Shares, Series W Preferred Shares, Series TH Preferred Shares and Series F Preferred Shares in proportion to the total dividends paid to each class with respect to such tax year. Dividends qualifying and not qualifying for (a) treatment as qualified dividend income and (b) the dividends received deduction, if any, will similarly be allocated between and among any such classes.

-71-

Return of Capital Distributions. If the Fund makes a distribution to a shareholder in excess of the Fund's current and accumulated earnings and profits in any taxable year, the excess distribution will be treated as a return of capital to the extent of the shareholder's tax basis in his shares, and thereafter as capital gain. A return of capital is not taxable, but it reduces a shareholder's tax basis in his shares, thus reducing any loss or increasing any gain on a subsequent taxable disposition by the shareholder of his shares. Where one or more such distributions occur in any taxable year of the Fund, the available earnings and profits will be allocated, first, to the distributions made to the holders of any outstanding preferred shares of beneficial interest of the Fund (including the Preferred Shares), and only thereafter to distributions made to Common Shareholders. As a result, the holders of any outstanding preferred shares of beneficial interest of the Fund (including the Preferred Shares) will receive a disproportionate share of the distributions treated as dividends, and the Common Shareholders will receive a disproportionate share of the distributions treated as a return of capital.

Dividends and distributions on the Fund's shares are generally subject to federal income tax as described herein to the extent they do not exceed the Fund's realized income and gains, even though such dividends and distributions may economically represent a return of a particular shareholder's investment. Such distributions are likely to occur in respect of shares purchased at a time when the Fund's net asset value reflects gains that are either unrealized, or realized but not distributed. Such realized gains may be required to be distributed even when the Fund's net asset value also reflects unrealized losses. Distributions are taxable to a shareholder even if they are paid from income or gains earned by the Fund prior to the shareholder's investment (and thus included in the price paid by the shareholders).

Capital Loss Carryover. Distributions from capital gains are generally made after applying any available capital loss carryovers.

Sale or Redemption of Shares. The sale, exchange or redemption of Fund shares may give rise to a gain or loss. In general, any gain or loss realized upon a taxable disposition of shares will be treated as long-term capital gain or loss if the shares have been held for more than 12 months. Otherwise, the gain or loss on the taxable disposition of Fund shares will be treated as short-term capital gain or loss. However, any loss realized upon a taxable disposition of shares held for six months or less will be treated as long-term, rather than short-term, to the extent of any long-term capital gain distributions received (or deemed received) by the shareholder with respect to the shares. All or a portion of any loss realized upon a taxable disposition of Fund shares will be disallowed if other substantially identical shares of the Fund are purchased within 30 days before or after the disposition. In such a case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.

From time to time the Fund may make a tender offer for its Common Shares. It is expected that the terms of any such offer will require a tendering shareholder to tender all Common Shares and dispose of all Preferred Shares held, or considered under certain attribution rules of the Code to be held, by such shareholder. Shareholders who tender all Common Shares and dispose of all Preferred Shares held, or considered to be held, by them will be treated as having sold their shares and generally will realize a capital gain or loss. If a shareholder tenders fewer than all of its Common Shares, or retains a substantial portion of its Preferred Shares, such shareholder may be treated as having received a taxable dividend upon the tender of its Common

-72-

Shares. In such a case, there is a remote risk that non-tendering shareholders will be treated as having received taxable distributions from the Fund. Likewise, if the Fund redeems some but not all of the Preferred Shares held by a Preferred Shareholder and such shareholder is treated as having received a taxable dividend upon such redemption, there is a remote risk that Common Shareholders and non-redeeming Preferred Shareholders will be treated as having received taxable distributions from the Fund. To the extent that the Fund recognizes net gains on the liquidation of portfolio securities to meet such tenders of Common Shares, the Fund will be required to make additional distributions to its Common Shareholders.

Discount Obligations and Payment-in-Kind Securities. Some of the debt obligations (with a fixed maturity date of more than one year from the date of issuance) that may be acquired by the Fund may be (and all zero-coupon debt obligations acquired by the Fund will be) treated as debt obligations that are issued originally at a discount. Generally, the amount of the original issue discount ("OID") is treated as interest income and is included in taxable income (and required to be distributed) over the term of the debt security, even though payment of that amount is not received until a later time, usually when the debt security matures. In addition, payment-in-kind securities will give rise to income which is required to be distributed and is taxable even though the Fund holding the security receives no interest payment in cash on the security during the year.

Some of the debt obligations (with a fixed maturity date of more than one year from the date of issuance) that may be acquired by the Fund in the secondary market may be treated as having market discount. Generally, any gain recognized on the disposition of, and any partial payment of principal on, a debt security having market discount is treated as ordinary income to the extent the gain, or principal payment, does not exceed the "accrued market discount" on such debt security. Market discount generally accrues in equal daily installments. The Fund may make one or more of the elections applicable to debt obligations having market discount, which could affect the character and timing of recognition of income.

Some debt obligations (with a fixed maturity date of one year or less from the date of issuance) that may be acquired by the Fund may be treated as having acquisition discount, or OID in the case of certain types of debt obligations. Generally, the Fund will be required to include the acquisition discount, or OID, in income over the term of the debt security, even though payment of that amount is not received until a later time, usually when the debt security matures. The Fund may make one or more of the elections applicable to debt obligations having acquisition discount, or OID, which could affect the character and timing of recognition of income.

If the Fund holds the foregoing kinds of securities, it may be required to pay out as an income distribution each year an amount which is greater than the total amount of cash interest the Fund actually received. Such distributions may be made from the cash assets of the Fund or by liquidation of portfolio securities, if necessary. The Fund may realize gains or losses from such liquidations. In the event the Fund realizes net capital gains from such transactions, its shareholders may receive a larger capital gain distribution than they would in the absence of such transactions.

-73-

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

Issuer Deductibility of Interest. A portion of the interest paid or accrued on certain high yield discount obligations owned by the Fund may not (and interest paid on debt obligations, if any, that are considered for tax purposes to be payable in the equity of the issuer or a related party will not) be deductible to the issuer. This may affect the cash flow of the issuer. If a portion of the interest paid or accrued on certain high yield discount obligations is not deductible, that portion will be treated as a dividend for purposes of the corporate dividends received deduction. In such cases, if the issuer of the high yield discount obligations is a domestic corporation, dividend payments by the Fund may be eligible for the dividends received deduction to the extent of the deemed dividend portion of such accrued interest.

Options, Futures, Forward Contracts and Swap Agreements. The Fund's transactions in options, futures contracts, hedging transactions, forward contracts, swap agreements, straddles and foreign currencies will be subject to special tax rules (including mark-to-market, constructive sale, straddle, wash sale and short sale rules), the effect of which may be to accelerate income to the Fund, defer losses to the Fund, cause adjustments in the holding periods of the Fund's securities, convert long-term capital gains into short-term capital gains and convert short-term capital losses into long-term capital losses. These rules could therefore affect the amount, timing and character of distributions to shareholders. The Fund will monitor its transactions, will make appropriate tax elections and will make appropriate entries in its books and records in order to mitigate the effect of these rules.

Certain of the Fund's hedging activities (including its transactions, if any, in foreign currencies or foreign currency-denominated instruments) are likely to produce a difference between its book income and its taxable income. If the Fund's book income exceeds its taxable income, the distribution (if any) of such excess generally will be treated as (i) a dividend to the extent of the Fund's remaining earnings and profits (including earnings and profits arising from tax-exempt income), (ii) thereafter, as a return of capital to the extent of the recipient's basis in its shares, and (iii) thereafter, as gain from the sale or exchange of a capital asset. If the Fund's book income is less than taxable income, the Fund could be required to make distributions exceeding book income to qualify as a regulated investment company that is accorded special tax treatment.

Foreign Currency Transactions. The Fund's transactions in foreign currencies, foreign currency-denominated debt obligations and certain foreign currency options, futures contracts and forward contracts (and similar instruments) may give rise to ordinary income or loss to the

-74-

extent such income or loss results from fluctuations in the value of the foreign currency concerned.

Foreign Taxation. Income received by the Fund from sources within foreign countries may be subject to withholding and other taxes imposed by such countries. Tax conventions between certain countries and the U.S. may reduce or eliminate such taxes. Shareholders generally will not be entitled to claim a credit or deduction with respect to foreign taxes.

Shares Purchased Through Tax-Qualified Plans. Special tax rules apply to investments through defined contribution plans and other tax-qualified plans. Shareholders should consult their tax advisers to determine the suitability of shares of the Fund as an investment through such plans and the precise effect of an investment on their particular tax situation.

Non-U.S. Shareholders. Under U.S. federal tax law, dividends other than Capital Gain Dividends paid on shares beneficially held by a person who is not a U.S. person within the meaning of the Code (or a "foreign person"), are, in general, subject to withholding of U.S. federal income tax at a rate of 30% of the gross dividend, which rate may, in some cases, be reduced by an applicable tax treaty. Dividends are subject to withholding even if they are funded by income or gains (such as portfolio interest, short-term capital gains, or foreign-source dividend and interest income) that, if paid to a foreign person directly, would not be subject to withholding. However, Capital Gain Dividends will not be subject to withholding of U.S. federal income tax. If a beneficial holder who is a foreign person has a trade or business in the United States, and the dividends are effectively connected with the conduct by the beneficial holder of a trade or business in the United States, the dividend will be subject to U.S. federal net income taxation at regular income tax rates.

Under U.S. federal tax law, a beneficial holder of shares who is a foreign person is not, in general, subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on the sale of shares of the Fund or on Capital Gain Dividends unless (i) such gain or Capital Gain Dividend is effectively connected with the conduct of a trade or business carried on by such holder within the United States or (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or Capital Gain Dividend and certain other conditions are met.

If you are eligible for the benefits of a tax treaty, any effectively connected income or gain will generally be subject to U.S. federal income tax on a net basis only if it is also attributable to a permanent establishment maintained by you in the United States.

A beneficial holder of shares who is a foreign person may be subject to state and local tax and to the U.S. federal estate tax in addition to the federal tax on income referred to above.

Backup Withholding. The Fund generally is required to withhold and remit to the U.S. Treasury a percentage of the taxable distributions and redemption proceeds paid to any individual shareholder who fails to properly furnish the Fund with a correct taxpayer identification number ("TIN"), who has under-reported dividend or interest income, or who fails to certify to the Fund that he or she is not subject to such withholding. The backup withholding tax rate is

-75-

28% for amounts paid through 2010. The backup withholding tax rate will be 31% for amounts paid after December 31, 2010.

In order for a foreign investor to qualify for exemption from the backup withholding tax rates under income tax treaties, the foreign investor must comply with special certification and filing requirements. Foreign investors in the Fund should consult their tax advisers in this regard. Backup withholding is not an additional tax. Any amounts withheld may be credited against the shareholder's U.S. federal income tax liability, provided the appropriate information is furnished to the Internal Revenue Service.

Recent Tax Shelter Reporting Regulations. Under recently promulgated Treasury regulations, if a shareholder recognizes a loss on disposition of the Fund's shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder, the shareholder must file with the Internal Revenue Service 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 advisers to determine the applicability of these regulations in light of their individual circumstances.

General. The federal income tax discussion set forth above is for general information only. Prospective investors should consult their tax advisers regarding the specific federal tax consequences of purchasing, holding, and disposing of shares of the Fund, as well as the effects of state, local and foreign tax law and any proposed tax law changes.

PERFORMANCE RELATED AND COMPARATIVE INFORMATION

The Fund may quote certain performance-related information and may compare certain aspects of its portfolio and structure to other substantially similar closed-end funds as categorized by Lipper, Inc. ("Lipper"), Morningstar Inc. or other independent services. Comparison of the Fund to an alternative investment should be made with consideration of differences in features and expected performance. The Fund may obtain data from sources or reporting services, such as Bloomberg Financial ("Bloomberg") and Lipper, that the Fund believes to be generally accurate.

The Fund, in its advertisements, may refer to pending legislation from time to time and the possible impact of such legislation on investors, investment strategy and related matters. At any time in the future, yields and total return may be higher or lower than past yields and there can be no assurance that any historical results will continue.

For the period from April 30, 2003 (the commencement of the Fund's operations) through June 11, 2003, the Fund's net increase in net assets resulting from investment operations was $51,992,137.

PIMCO HIGH INCOME FUND
NOTES TO FINANCIAL STATEMENTS
June 1, 2003
(unaudited)

1. Organization and Significant Accounting Policies

PIMCO High Income Fund (the "Fund") was organized as a Massachusetts business trust on February 18, 2003. Prior to commencing operations on April 30, 2003, the Fund had no operations other than matters relating to its organization and registration as a diversified, closed-end management investment company under the Investment Company Act of 1940, as amended, and the sale and issuance of 6,981 shares of beneficial interest at an aggregate purchase price of $100,003 to Allianz Dresdner Asset Management of America, L.P. ("ADAM"). PIMCO Advisors Fund Management LLC (the "Investment Manager") serves as the Fund's investment manager and is an indirect wholly-owned subsidiary of ADAM which is an indirect, majority-owned subsidiary of Allianz AG, a publicly traded insurance and financial services company.

The Investment Manager agreed to reimburse the amount by which the aggregate of all the Fund's organizational expenses and offering costs (other than the sales load) exceeds $0.03 per share of the initial offering. There are an unlimited number of $0.00001 per share par value common stock authorized.

The Fund issued 105,000,000 common shares of beneficial interest in its initial public offering. An additional 7,000,000 shares were issued in connection with the underwriter's over-allotment option. These shares were all issued at $15.00 per share before an underwriting discount of $0.675 per share. Offering costs of $1,575,000 (representing $0.015 per share) were offset against the proceeds of the initial offering and have been charged to paid-in capital in excess of par.

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 and disclosures in the financial statements. Actual results could differ from these estimates. In the normal course of business, the Fund enters into contracts that contain a variety of representations which provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would involve future claims that may be made against the Fund that have not yet occurred. However, the Fund expects the risk of loss to be remote.

The following is a summary of significant accounting policies followed by the Fund:

(a) Valuation of Investments

Portfolio securities and other assets for which market quotations are readily available are valued each day at market value. Market value is generally determined on the basis of the last reported sales price, or if no sales are reported, based on quotes obtained from a quotation reporting system, established market makers, or independent pricing services approved by the Board of Trustees. Any security or other asset for which market quotations are not readily available is valued at fair value as determined in good faith under procedures established by the Board of

-82-

Trustees. The Fund invests substantially all of its assets in a diversified portfolio of corporate debt obligations of varying maturities and other corporate income-producing securities. Short-term debt securities having a remaining maturity of sixty days or less are valued at amortized cost or amortized value, which approximates market value.

(b) Investment Transactions and Investment Income

Investment transactions are accounted for on the trade date. Realized gains and losses on investments are determined on the identified cost basis. Interest income is recorded on an accrual basis. Discounts or premiums on debt securities purchased are accreted or amortized to interest income over the lives of the respective securities using the effective interest method. Market discount, if any, is accreted daily.

(c) Repurchase Agreements

The Fund may enter into transactions with its custodian bank or securities brokerage firms approved by the Board of Trustees whereby it purchases securities under agreements to resell at an agreed upon price and date ("repurchase agreements"). Such agreements are carried at the contract amount in the financial statements. Collateral pledged (the securities received), which consists primarily of U.S. government obligations and asset backed securities, are held by the custodian bank until maturity of the repurchase agreement. Provisions of the repurchase agreements and the procedures adopted by the Fund require that the value of the collateral, including accrued interest thereon, is sufficient in the event of default by the counterparty. If the counterparty defaults and the value of the collateral declines or if the counterparty enters an insolvency proceeding, realization of the collateral by the Fund may be delayed or limited.

(d) Swaps

The Fund may invest in interest rate and credit default swaps contracts ("swaps") for investment purposes, to manage its interest rates and credit risks and to add leverage to the Portfolio.

As a seller in the credit default swap contract, the Fund would be required to pay the par or other agreed-upon value of a referenced debt obligation to the counterparty in the event of default by a third party, such a as a U.S. or foreign corporate issuer, on the referenced debt obligation. In return, the Fund would receive from the counterparty a periodic stream of payments over the term of the contract provided that no event of default had occurred. If no default occurs, the Fund would keep the stream of payments and would have no payment obligations. Such periodic payments are accrued daily and recorded as interest income.

The Fund may also purchase credit default swap contracts in order to hedge against the risk of default of debt securities held in its portfolio, in which case the Fund would function as the counterparty referenced in the preceding paragraph. As a purchaser of a credit default swap contract, the Fund would receive the par or other agreed upon value of a referenced debt obligation from the counterparty in the event of default by a third party, such as a U.S. or foreign corporate issuer on the referenced debt obligation. In return, the Fund would make periodic payments to the counterparty over the term of the contract provided no event of default has occurred. Such periodic payments are accrued daily and charged to interest income by the Fund.

Interest rate swap agreements involve the exchange by the Fund with a counterparty of their respective commitments to pay or receive interest, e.g. an exchange of floating rate payments for

-83-

fixed rate payments with respect to a notional amount of principal. Net payments of interest on interest rate swap agreements are recorded daily as part of interest income.

Swaps are marked to market daily by the Fund's Investment Manager based upon quotations from market makers and the change in value, if any, is recorded as unrealized appreciation or depreciation in the Statement of Operations by the Fund. Payments received or made, if any, upon termination or maturity of the interest rate swaps, net of any basis in the interest rate swaps, is recorded as a realized gain or loss in the Statement of Operations by the Fund. For a credit default swap sold by the Fund, payment of the agreed upon amount made by the Fund in the event of default of the referenced debt obligation is recorded as the cost of the referenced debt obligation purchased/received. For a credit default swap purchased by the Fund, the agreed upon amount received by the Fund in the event of default of the referenced debt obligation is recorded as proceeds from sale/delivery of the referenced debt obligation and the resulting gain or loss realized on the referenced debt obligation is recorded as such by the Fund.

Entering into swaps involves, to varying degrees, elements of credit, market and documentation risk in excess of the amounts recognized on the Statement of Assets and Liabilities. Such risks involve the possibility that there will be no liquid market for these agreements, that the counterparty to the agreements may default on its obligation to perform or disagree as to the meaning of the contractual terms in the agreements, and that there may be unfavorable changes in the interest rates.

Credit default swap contracts outstanding at June 1, 2003 were as follows:

--------------------------------------------------------------------------------
                     Notional    Termination      Fixed          Unrealized

Hydromer, Inc.
3.15%, 11/15/07
--------------------------------------------------------------------------------

(e) Loan Participation

The Fund may invest in loan participations. When the Fund purchases a loan participation, the Fund typically enters into a contractual relationship with the lender or third party selling such participations ("Selling Participant"), but not the borrower. As a result, the Fund assumes the credit risk of the borrower, the Selling Participant and any other persons interposed between the Fund and the borrower. The Fund may not directly benefit from the collateral supporting the senior loan in which it has purchased the loan participation.

2. Investment Manager and Sub-Adviser

The Fund has entered into an Investment Management Agreement (the "Agreement'), with the Investment Manager to serve as investment manager to the Fund. Pursuant to the Agreement, the Fund will pay the Investment Manager an annual management fee, payable monthly, at the annual rate of 0.70% of the Fund's average daily net assets (including assets attributable to any preferred shares that may be outstanding). The Investment Manager has retained its affiliate, Pacific Investment Management Company LLC ("PIMCO"), to manage the Fund's investments. For its services, the Investment Manager (not the Fund) will pay a portion of the fees it receives as investment manager to PIMCO at the annual rate of 0.3575% of the Fund's average daily net assets (including assets attributable to any preferred shares that may be outstanding) for the period from April 30, 2003 (commencement of operations) through April 30, 2008 and at the annual rate of 0.50% of average daily net assets (including assets attributable to any preferred shares that may be outstanding) thereafter.

-84-

3. Federal Income Taxes

The Fund intends to comply with the requirements of the Internal Revenue Code of 1986, as amended, applicable to regulated investment companies. Accordingly, no provision for U.S. federal income taxes is required. In addition, by distributing substantially all of its ordinary income and long-term capital gains, if any, during each calendar year, the Fund intends not to be subject to U. S. federal excise tax.

4. Investment in Securities

For the period April 30, 2003 through June 1, 2003, purchases and sales of investments, other than short-term securities, aggregated $1,630,149,603 and $94,306,896, respectively.

5. Subsequent Event

On June 6, 2003 the underwriters purchased at a price of $15.00 per common share, an additional 1,900,000 common shares of the Fund pursuant to the over-allotment option. On June 10, 2003, a dividend of $0.121875 per share was declared to common shareholders payable July 1, 2003 to shareholder of record on June 20, 2003.

APPENDIX A

AUCTION PROCEDURES

The following procedures will be set forth in provisions of the Bylaws relating to the Preferred Shares, and will be incorporated by reference in the Auction Agency Agreement and each Broker-Dealer Agreement. The terms not defined below are defined in the Prospectus, except that the term "Trust" means the Fund. Nothing contained in this Appendix A constitutes a representation by the Fund that in each Auction each party referred to herein actually will perform the procedures described herein to be performed by such party.

ARTICLE 11

* * *

11.10 Auction Procedures. (a) Certain Definitions. As used in this Section 11.10, the following terms shall have the following meanings, unless the context otherwise requires:

(i) "Auction Date" means the first Business Day preceding the first day of a Dividend Period.

(ii) "Available Preferred Shares" has the meaning specified in
Section 11.10(d)(i)(A) below.

(iii) "Bid" has the meaning specified in Section 11.10(b)(i)(B) below.

(iv) "Bidder" has the meaning specified in Section 11.10(b)(i)(B) below.

(v) "Hold Order" has the meaning specified in Section 11.10(b)(i)(B) below.

(vi) "Maximum Applicable Rate" for any Dividend Period will be the Applicable Percentage of the Reference Rate. The Auction Agent will round each applicable Maximum Applicable Rate to the nearest one-thousandth
(0.001) of one percent per annum, with any such number ending in five ten-thousandths of one percent being rounded upwards to the nearest one-thousandth (0.001) of one percent. The Auction Agent will not round the applicable Reference Rate as part of its calculation of the Maximum Applicable Rate. The "Applicable Percentage" shall be the percentage determined based on the lower of the credit ratings assigned on such date by Moody's and Fitch Ratings as follows:

   Moody's        Fitch Applicable
Credit Rating      Credit Rating      Percentage
                   -------------      ----------
Aa3 or above       AA- or above          150%
  A3 to A1           A- to A+            160%
Baa3 to Baa1       BBB- to BBB+          250%
 Below Baa3         Below BBB-           275%

A-1

The Applicable Percentage as so determined shall be further subject to upward but not downward adjustment in the discretion of the Board of Trustees of the Trust after consultation with the Broker-Dealers, provided that the Board of Trustees has received assurance from Moody's and Fitch Ratings and from any other Rating Agency then rating the Preferred Shares that such increase will not impair such Rating Agency's rating thereof, and further provided that immediately following any such increase the Trust would be in compliance with the Preferred Shares Basic Maintenance Amount. The Trust shall take all reasonable action necessary to enable Moody's and Fitch Ratings to provide a rating for each series of Preferred Shares. If Moody's or Fitch Ratings shall not make such a rating available, Citigroup Global Markets Inc. or its affiliates and successors, after consultation with the Trust, shall select another Rating Agency to act as a Substitute Rating Agency.

(vii) "Order" has the meaning specified in Section 11.10(b)(i)(B) below.

(viii) "Preferred Shares" means the Preferred Shares being auctioned pursuant to this Section 11.10.

(ix) "Sell Order" has the meaning specified in Section 11.10(b)(i)(B) below.

(x) "Submission Deadline" means 1:00 p.m., New York City time, on any Auction Date or such other time on any Auction Date as may be specified by the Auction Agent from time to time as the time by which each Broker-Dealer must submit to the Auction Agent in writing all Orders obtained by it for the Auction to be conducted on such Auction Date.

(xi) "Submitted Bid" has the meaning specified in Section 11.10(d)(i) below.

(xii) "Submitted Hold Order" has the meaning specified in Section 11.10(d)(i) below.

(xiii) "Submitted Order" has the meaning specified in Section 11.10(d)(i) below.

(xiv) "Submitted Sell Order" has the meaning specified in Section 11.10(d)(i) below.

(xv) "Sufficient Clearing Bids" has the meaning specified in Section 11.10(d)(i) below.

(xvi) "Winning Bid Rate" has the meaning specified in Section 11.10(d)(i)(c) below.

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

(i) Unless otherwise permitted by the Trust, Beneficial Owners and Potential Beneficial Owners may only participate in Auctions through their Broker-Dealers. Broker-Dealers will submit the Orders of their respective customers who are Beneficial

A-2

Owners and Potential Beneficial Owners to the Auction Agent, designating themselves as Existing Holders in respect of shares subject to Orders submitted or deemed submitted to them by Beneficial Owners and as Potential Holders in respect of shares subject to Orders submitted to them by Potential Beneficial Owners. A Broker-Dealer may also hold Preferred Shares in its own account as a Beneficial Owner. A Broker-Dealer may thus submit Orders to the Auction Agent as a Beneficial Owner or a Potential Beneficial Owner and therefore participate in an Auction as an Existing Holder or Potential Holder on behalf of both itself and its customers. On or prior to the Submission Deadline on each Auction Date:

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

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

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

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

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

For the purposes hereof, the communication by a Beneficial Owner or Potential Beneficial Owner to a Broker-Dealer, or the communication by a Broker-Dealer acting for its own account to the Auction Agent, of information referred to in clause (A) or (B) of this Section 11.10(b)(i) is hereinafter referred to as an "Order" and each Beneficial Owner and each Potential Beneficial Owner placing an Order, including a Broker-Dealer acting in such capacity for its own account, is hereinafter referred to as a "Bidder"; an Order containing the information referred to in clause (A)(1) of this Section 11.10(b)(i) is hereinafter referred to as a "Hold Order"; an

A-3

Order containing the information referred to in clause (A)(2) or (B) of this Section 11.10(b)(i) is hereinafter referred to as a "Bid"; and an Order containing the information referred to in clause (A)(3) of this Section 11.10(b)(i) is hereinafter referred to as a "Sell Order." Inasmuch as a Broker-Dealer participates in an Auction as an Existing Holder or a Potential Holder only to represent the interests of a Beneficial Owner or Potential Beneficial Owner, whether it be its customers or itself, all discussion herein relating to the consequences of an Auction for Existing Holders and Potential Holders also applies to the underlying beneficial ownership interests represented.

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

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

(2) such number or a lesser number of Outstanding Preferred Shares to be determined as set forth in Section 11.10(e)(i)(D) if the Applicable Rate determined on such Auction Date shall be equal to the rate per annum specified therein; or

(3) a lesser number of Outstanding Preferred Shares to be determined as set forth in Section 11.10(e)(ii)(C) if such specified rate per annum shall be higher than the Maximum Applicable Rate and Sufficient Clearing Bids do not exist.

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

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

(2) such number or a lesser number of Outstanding Preferred Shares to be determined as set forth in Section 11.10(e)(ii)(C) if Sufficient Clearing Bids do not exist.

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

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

(2) such number or a lesser number of Outstanding Preferred Shares to be determined as set forth in Section 11.10(e)(i)(E) if the Applicable Rate determined on such Auction Date shall be equal to the rate per annum specified therein.

A-4

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

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

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

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

(C) to the extent that such Bidder is a Beneficial Owner or an Existing Holder:

(1) the number of Outstanding Preferred Shares, if any, subject to any Hold Order placed by such Beneficial Owner or Existing Holder;

(2) the number of Outstanding Preferred Shares, if any, subject to any Bid placed by such Beneficial Owner or Existing Holder and the rate per annum specified in such Bid; and

(3) the number of Outstanding Preferred Shares, if any, subject to any Sell Order placed by such Beneficial Owner or Existing Holder; and

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

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

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

A-5

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

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

(B) any Bids submitted on behalf of such Existing Holder shall be considered valid, in the ascending order of their respective rates per annum if more than one Bid is submitted on behalf of such Existing Holder, up to and including the excess of the number of Outstanding Preferred Shares held by such Existing Holder over the number of Preferred Shares subject to any Hold Order referred to in Section 11.10(c)(iv)(A) above (and if more than one Bid submitted on behalf of such Existing Holder specifies the same rate per annum and together they cover more than the remaining number of shares that can be the subject of valid Bids after application of Section 11.10(c)(iv)(A) above and of the foregoing portion of this Section 11.10(c)(iv)(B) to any Bid or Bids specifying a lower rate or rates per annum, the number of shares subject to each of such Bids shall be reduced pro rata so that such Bids, in the aggregate, cover exactly such remaining number of shares); and the number of shares, if any, subject to Bids not valid under this Section 11.10(c)(iv)(B) shall be treated as the subject of a Bid by a Potential Holder; and

(C) any Sell Order shall be considered valid up to and including the excess of the number of Outstanding Preferred Shares held by such Existing Holder over the number of Preferred Shares subject to Hold Orders referred to in Section 11.10(c)(iv)(A) and Bids referred to in
Section 11.10(c)(iv)(B); provided that if more than one Sell Order is submitted on behalf of any Existing Holder and the number of Preferred Shares subject to such Sell Orders is greater than such excess, the number of Preferred Shares subject to each of such Sell Orders shall be reduced pro rata so that such Sell Orders, in the aggregate, cover exactly the number of Preferred Shares equal to such excess.

A-6

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

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

(vii) The Trust shall not be responsible for a Broker-Dealer's failure to act in accordance with the instructions of Beneficial Owners or Potential Beneficial Owners or failure to comply with the provisions of this Section 11.10.

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

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

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

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

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

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

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

A-7

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

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

(ii) Promptly after the Auction Agent has made the determinations pursuant to Section 11.10(d)(i), the Auction Agent shall advise the Trust of the Maximum Applicable Rate and, based on such determinations, the Applicable Rate for the next succeeding Dividend Period as follows:

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

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

(C) if all of the Outstanding Preferred Shares are the subject of Submitted Hold Orders, that the Dividend Period next succeeding the Auction shall automatically be the same length as the immediately preceding Dividend Period and the Applicable Rate for the next succeeding Dividend Period shall be equal to 80% of the Reference Rate on the date of the Auction.

(e) Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares. Existing Holders shall continue to hold the Preferred Shares that are subject to Submitted Hold Orders, and, based on the determinations made pursuant to Section 11.10(d)(i), the Submitted Bids and Submitted Sell Orders shall be accepted or rejected and the Auction Agent shall take such other action as set forth below:

(i) If Sufficient Clearing Bids have been made, subject to the provisions of Section 11.10(e)(iii) and Section 11.10(e)(iv), Submitted Bids and Submitted Sell Orders shall be accepted or rejected in the following order of priority and all other Submitted Bids shall be rejected:

A-8

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

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

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

(D) the Submitted Bid of each of the Existing Holders specifying a rate per annum that is equal to the Winning Bid Rate shall be rejected, thus entitling each such Existing Holder to continue to hold the Outstanding Preferred Shares that are the subject of such Submitted Bid, unless the number of Outstanding Preferred Shares subject to all such Submitted Bids shall be greater than the number of Outstanding Preferred Shares ("Remaining Shares") equal to the excess of the Available Preferred Shares over the number of Outstanding Preferred Shares subject to Submitted Bids described in Section 11.10(e)(i)(B) and
Section 11.10(e)(i)(C), in which event the Submitted Bids of each such Existing Holder shall be accepted, and each such Existing Holder shall be required to sell Outstanding Preferred Shares, but only in an amount equal to the difference between (1) the number of Outstanding Preferred Shares then held by such Existing Holder subject to such Submitted Bid and (2) the number of Preferred Shares obtained by multiplying (x) the number of Remaining Shares by (y) 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 sum of the number of Outstanding Preferred Shares subject to such Submitted Bids made by all such Existing Holders that specified a rate per annum equal to the Winning Bid Rate; and

(E) the Submitted Bid of each of the Potential Holders specifying a rate per annum that is equal to the Winning Bid Rate shall be accepted but only in an amount equal to the number of Outstanding Preferred Shares obtained by multiplying (x) the difference between the Available Preferred Shares and

A-9

the number of Outstanding Preferred Shares subject to Submitted Bids described in Section 11.10(e)(i)(B), Section 11.10(e)(i)(C) and
Section 11.10(e)(i)(D) by (y) 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 number of Outstanding Preferred Shares subject to such Submitted Bids made by all such Potential Holders that specified rates per annum equal to the Winning Bid Rate.

(ii) If Sufficient Clearing Bids have not been made (other than because all of the Outstanding Preferred Shares are subject to Submitted Hold Orders), subject to the provisions of Section 11.10(e)(iii), Submitted Orders shall be accepted or rejected as follows in the following order of priority and all other Submitted Bids shall be rejected:

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

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

(C) the Submitted Bids of each Existing Holder specifying any rate per annum that is higher than the Maximum Applicable Rate shall be accepted and the Submitted Sell Orders of each Existing Holder shall be accepted, in both cases only in an amount equal to the difference between (1) the number of Outstanding Preferred Shares then held by such Existing Holder subject to such Submitted Bid or Submitted Sell Order and (2) the number of Preferred Shares obtained by multiplying (x) the difference between the Available Preferred Shares and the aggregate number of Outstanding Preferred Shares subject to Submitted Bids described in Section 11.10(e)(ii)(A) and
Section 11.10(e)(ii)(B) by (y) a fraction the numerator of which shall be the number of Outstanding Preferred Shares held by such Existing Holder subject to such Submitted Bid or Submitted Sell Order and the denominator of which shall be the number of Outstanding Preferred Shares subject to all such Submitted Bids and Submitted Sell Orders.

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.

A-10

(iii) If, as a result of the procedures described in Section 11.10(e), 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 Preferred Share on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, round up or down the number of Preferred Shares to be purchased or sold by any Existing Holder or Potential Holder on such Auction Date so that each Outstanding Preferred Share purchased or sold by each Existing Holder or Potential Holder on such Auction Date shall be a whole Preferred Share.

(iv) If, as a result of the procedures described in Section 11.10(e), any Potential Holder would be entitled or required to purchase less than a whole Preferred Share on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, allocate Preferred Shares for purchase among Potential Holders so that only whole Preferred Shares are purchased on such Auction Date by any Potential Holder, even if such allocation results in one or more of such Potential Holders not purchasing any Preferred Shares on such Auction Date.

(v) Based on the results of each Auction, the Auction Agent shall determine, with respect to each Broker-Dealer that submitted Bids or Sell Orders on behalf of Existing Holders or Potential Holders, the aggregate number of Outstanding Preferred Shares to be purchased and the aggregate number of the Outstanding Preferred Shares to be sold by such Potential Holders and Existing Holders and, to the extent that such aggregate number of Outstanding shares to be purchased and such aggregate number of Outstanding shares to be sold differ, the Auction Agent shall determine to which other Broker-Dealer or Broker-Dealers acting for one or more purchasers such Broker-Dealer shall deliver, or from which other Broker-Dealer or Broker-Dealers acting for one or more sellers such Broker-Dealer shall receive, as the case may be, Outstanding Preferred Shares.

(f) Miscellaneous.

(i) To the extent permitted by applicable law, the Trust may in its sole discretion interpret the provisions of this Section 11.10 to resolve any inconsistency or ambiguity, remedy any formal defect or make any other change or modification that does not substantially adversely affect the rights of Beneficial Owners of Preferred Shares.

(ii) Unless otherwise permitted by the Trust, a Beneficial Owner or an Existing Holder (A) may sell, transfer or otherwise dispose of Preferred Shares only pursuant to a Bid or Sell Order in accordance with the procedures described in this Section 11.10 or to or through a Broker-Dealer or to such other persons as may be permitted by the Trust, provided that in the case of all transfers other than pursuant to Auctions such Beneficial Owner or Existing Holder, its Broker-Dealer, if applicable, or its Agent Member advises the Auction Agent of such transfer and (B) except as otherwise required by law, shall have the ownership of the Preferred Shares held by it maintained in book entry form by the Securities Depository in the account of its Agent

A-11

Member, which in turn will maintain records of such Beneficial Owner's beneficial ownership. The Trust may not submit an Order in any Auction.

(iii) All of the Outstanding Preferred Shares of a series shall be registered in the name of the nominee of the Securities Depository unless otherwise required by law or unless there is no Securities Depository. If there is no Securities Depository, at the Trust's option and upon its receipt of such documents as it deems appropriate, any Preferred Shares may be registered in the Stock Register in the name of the Beneficial Owner thereof and such Beneficial Owner thereupon will be entitled to receive certificates therefor and required to deliver certificates therefor upon transfer or exchange thereof.

A-12

APPENDIX B

SETTLEMENT PROCEDURES

The following summary of Settlement Procedures sets forth the procedures expected to be followed in connection with the settlement of each Auction and will be incorporated by reference in the Auction Agency Agreement and each Broker-Dealer Agreement. Nothing contained in this Appendix B constitutes a representation by the Fund that in each Auction each party referred to herein actually will perform the procedures described herein to be performed by such party. Capitalized terms used herein shall have the respective meanings specified in the glossary of the Prospectus or Appendix A hereto, as the case may be.

(a) On each Auction Date, the Auction Agent shall notify by telephone or through the Auction Agent's auction processing system the Broker-Dealers that participated in the Auction held on such Auction Date and submitted an Order on behalf of any Beneficial Owner or Potential Beneficial Owner of:

(i) the Applicable Rate fixed for the next succeeding Dividend Period;

(ii) whether Sufficient Clearing Bids existed for the determination of the Applicable Rate;

Item 29: Indemnification

Reference is made to Article VIII, Sections 1 through 4, of the Registrant's Agreement and Declaration of Trust, which is incorporated by reference herein.

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

ARTICLE 9
Issuance of Share Certificates

9.1 Share Certificates. Except as provided in Article 11 hereof, each Shareholder shall be entitled to a certificate stating the number of Shares (as defined in the Declaration of Trust) owned by him or her, in such form as shall be prescribed from time to time by the Trustees. Such certificates shall be signed by the President or any Vice President and by the Treasurer or any Assistant Treasurer. Such signatures may be by facsimile if the certificate is signed by a transfer agent, or by a registrar, other than a Trustee, officer or employee of the Trust. In case any officer who has signed or whose facsimile signature has been placed on such certificate shall cease to be such officer before such certificate is issued, it may be issued by the Trust with the same effect as if he or she were such officer at the time of its issuance.

-4-

Notwithstanding the foregoing, in lieu of issuing certificates for Shares, the Trustees or the transfer agent may either issue receipts therefor or may keep accounts upon the books of the Trust for the record holders of such Shares, who shall in either case be deemed, for all purposes hereunder, to be the holders of certificates for such Shares as if they had accepted such certificates and shall be held to have expressly assented and agreed to the terms hereof.

9.2 Loss of Certificates. In case of the alleged loss or destruction or the mutilation of a share certificate, a duplicate certificate may be issued in place thereof, upon such terms as the Trustees shall prescribe.

9.3 Issuance of New Certificates to Pledgee. A pledgee of Shares transferred as collateral security shall be entitled to a new certificate if the instrument of transfer substantially describes the debt or duty that is intended to be secured thereby. Such new certificate shall express on its face that it is held as collateral security, and the name of pledgor shall be stated thereon, who alone shall be liable as a Shareholder and entitled to vote thereon.

9.4 Discontinuance of Issuance of Certificates. Notwithstanding anything to the contrary in this Article 9, the Trustees may at any time discontinue the issuance of share certificates and may, by written notice to each Shareholder, require the surrender of share certificates to the Trust for cancellation. Such surrender and cancellation shall not effect the ownership of Shares in the Trust.

ARTICLE 10
Shareholders' Voting Powers and Meetings

10.1 Voting Powers. The Shareholders shall have power to vote only (i) for the election or removal of Trustees as provided in Article IV, Sections 1 and 3 of the Declaration of Trust and Article 11 hereto, (ii) with respect to any Manager or sub-adviser as provided in Article IV, Section 8 of the Declaration of Trust to the extent required by the 1940 Act, (iii) with respect to certain transactions and other matters to the extent and as provided in Article V, Sections 2 and 3 of the Declaration of Trust and Article 11 hereto, (iv) with respect to any termination of this Trust to the extent and as provided in Article IX, Section 4 of the Declaration of Trust and Article 11 hereto (for the avoidance of any doubt, Shareholders shall have no separate right to vote with respect to the termination of the Trust or a series or class of Shares if the Trustees (including the Continuing Trustees) exercise their right to terminate the Trust or such series or class pursuant to clauses (ii) or (y) of Article IX,
Section 4 of the Declaration of Trust), (v) with respect to any amendment of the Declaration of Trust to the extent and as provided in Article IX, Section 7 of the Declaration of Trust and Articles 11 and 12 hereto, (vi) to the same extent as the stockholders of a Massachusetts business corporation as to whether or not a court action, proceeding or claim should or should not be brought or maintained derivatively or as a class action on behalf of the Trust or the Shareholders, and (vii) with respect to such additional matters relating to the Trust as may be required by law, the Declaration of Trust, these Bylaws or any registration of the Trust with the Securities and Exchange Commission (or any successor agency) or any state, or as the Trustees may consider necessary or desirable. Each whole Share shall be entitled to one vote as to any matter on which it is entitled to vote and each fractional Share shall be entitled to a proportionate fractional vote, except as

-5-

otherwise provided in the Declaration of Trust, these Bylaws, or required by applicable law. Except as otherwise provided in the Declaration of Trust or in respect of the terms of a class of preferred shares of beneficial interest of the Trust as reflected in these Bylaws or required by applicable law, all Shares of the Trust then entitled to vote shall be voted in the aggregate as a single class without regard to classes or series of Shares. There shall be no cumulative voting in the election of Trustees. Shares may be voted in person or by proxy. A proxy with respect to Shares held in the name of two or more persons shall be valid if executed by any one of them unless at or prior to exercise of the proxy the Trust receives a specific written notice to the contrary from any one of them. The placing of a Shareholder's name on a proxy pursuant to telephonic or electronically transmitted instructions obtained pursuant to procedures reasonably designed to verify that such instructions have been authorized by such Shareholder shall constitute execution of such proxy by or on behalf of such Shareholder. A proxy purporting to be executed by or on behalf of a Shareholder shall be deemed valid unless challenged at or prior to its exercise and the burden of proving invalidity shall rest on the challenger. Until Shares of a particular class or series are issued, the Trustees may exercise all rights of Shareholders and may take any action required by law, the Declaration of Trust or these Bylaws to be taken by Shareholders as to such class or series.

10.2 Voting Power and Meetings. Except as provided in the next sentence, regular meetings of the Shareholders for the election of Trustees and the transaction of such other business as may properly come before the meeting shall be held, so long as Common Shares are listed for trading on the New York Stock Exchange, on at least an annual basis, on such day and at such place as shall be designated by the Trustees. In the event that such a meeting is not held in any annual period if so required, whether the omission be by oversight or otherwise, a subsequent special meeting may be called by the Trustees and held in lieu of such meeting with the same effect as if held within such annual period. Special meetings of the Shareholders or any or all classes or series of Shares may also be called by the Trustees from time to time for such other purposes as may be prescribed by law, by the Declaration of Trust or by these Bylaws, or for the purpose of taking action upon any other matter deemed by a majority of the Trustees and a majority of the Continuing Trustees to be necessary or desirable. A special meeting of Shareholders may be held at any such time, day and place as is designated by the Trustees. Written notice of any meeting of Shareholders, stating the date, time, place and purpose of the meeting, shall be given or caused to be given by a majority of the Trustees and a majority of the Continuing Trustees at least seven days before such meeting to each Shareholder entitled to vote thereat by leaving such notice with the Shareholder at his or her residence or usual place of business or by mailing such notice, postage prepaid, to the Shareholder's address as it appears on the records of the Trust. Such notice may be given by the Secretary or an Assistant Secretary or by any other officer or agent designated for such purpose by the Trustees. Whenever notice of a meeting is required to be given to a Shareholder under the Declaration of Trust or these Bylaws, a written waiver thereof, executed before or after the meeting by such Shareholder or his or her attorney thereunto authorized and filed with the records of the meeting, shall be deemed equivalent to such notice. Notice of a meeting need not be given to any Shareholder who attends the meeting without protesting prior thereto or at its commencement the lack of notice to such Shareholder. No ballot shall be required for any election unless required by a Shareholder present or represented at the meeting and entitled to vote in such election. Notwithstanding anything to the contrary in this Section 10.2, no matter shall be properly before any annual or

-6-

special meeting of Shareholders and no business shall be transacted thereat unless in accordance with Section 10.6 of these Bylaws.

10.3 Quorum and Required Vote. Except when a larger quorum is required by any provision of law or the Declaration of Trust or these Bylaws, thirty percent (30%) of the Shares entitled to vote on a particular matter shall constitute a quorum for the transaction of business at a Shareholders' meeting, except that where any provision of law or the Declaration of Trust or these Bylaws permits or requires that holders of any class or series of Shares shall vote as an individual class or series, then thirty percent (30%) (unless a larger quorum is required as specified above) of Shares of that class or series entitled to vote shall be necessary to constitute a quorum for the transaction of business by that class or series. Any lesser number shall be sufficient for adjournments. Any adjourned session or sessions may be held, within a reasonable time after the date set for the original meeting, without the necessity of further notice. Except when a different vote is required by any provision of law or the Declaration of Trust or these Bylaws, a plurality of the quorum of Shares necessary for the transaction of business at a Shareholders' meeting shall decide any questions and a plurality of Shares voted shall elect a Trustee, provided that where any provision of law or of the Declaration of Trust or these Bylaws permits or requires that the holders of any class or series of Shares shall vote as an individual class or series, then a plurality of the quorum of Shares of that class or series necessary for the transaction of business by that class or series at a Shareholders' meeting shall decide that matter insofar as that class or series is concerned.

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

10.5 Record Dates. For the purpose of determining the Shareholders who are entitled to vote or act at any meeting or any adjournment thereof, or who are entitled to receive payment of any dividend or of any other distribution, the Trustees may from time to time fix a time, which shall be not more than 90 days before the date of any meeting of Shareholders or the date for the payment of any dividend or of any other distribution, as the record date for determining the Shareholders having the right to notice of and to vote at such meeting and any adjournment thereof or the right to receive such dividend or distribution, and in such case only Shareholders of record on such record date shall have the right notwithstanding any transfer of Shares on the books of the Trust after the record date; or without fixing such record date the Trustees may for any of such purposes close the register or transfer books for all or any part of such period.

10.6 Advance Notice of Shareholder Nominees for Trustees and Other Shareholder Proposals. (a) As used in this Section 10.6, the term "annual meeting" refers to any annual meeting of Shareholders as well as any special meeting held in lieu of an annual meeting as described in the first two sentences of Section 10.2 of these Bylaws, and the term "special meeting" refers to all meetings of Shareholders other than an annual meeting or a special meeting in lieu of an annual meeting.

-7-

(b) The matters to be considered and brought before any annual or special meeting of Shareholders shall be limited to only such matters, including the nomination and election of Trustees, as shall be brought properly before such meeting in compliance with the procedures set forth in this Section 10.6. Only persons who are nominated in accordance with the procedures set forth in this
Section 10.6 shall be eligible for election as Trustees, and no proposal to fix the number of Trustees shall be brought before an annual or special meeting of Shareholders or otherwise transacted unless in accordance with the procedures set forth in this Section 10.6, except as may be otherwise provided in these Bylaws with respect to the right of holders of preferred shares of beneficial interest, if any, of the Trust to nominate and elect a specified number of Trustees in certain circumstances.

(c) For any matter to be properly before any annual meeting, the matter must be (i) specified in the notice of meeting given by or at the direction of a majority of the Trustees and a majority of the Continuing Trustees pursuant to
Section 10.2 of these Bylaws, (ii) otherwise brought before the meeting by or at the direction of a majority of the Continuing Trustees (or any duly authorized committee thereof), or (iii) brought before the meeting in the manner specified in this Section 10.6(c) by a Shareholder of record entitled to vote at the meeting or by a Shareholder (a "Beneficial Owner") that holds Shares entitled to vote at the meeting through a nominee or "street name" holder of record and that can demonstrate to the Trust such indirect ownership and such Beneficial Owner's entitlement to vote such Shares, provided that the Shareholder was the Shareholder of record or the Beneficial Owner held such Shares at the time the notice provided for in this Section 10.6(c) is delivered to the Secretary.

In addition to any other requirements under applicable law and the Declaration of Trust and these Bylaws, persons nominated by Shareholders for election as Trustees and any other proposals by Shareholders may be properly brought before an annual meeting only pursuant to timely notice (the "Shareholder Notice") in writing to the Secretary. To be timely, the Shareholder Notice must be delivered to or mailed and received at the principal executive offices of the Trust not less than forty-five (45) nor more than sixty (60) days prior to the first anniversary date of the date on which the Trust first mailed its proxy materials for the prior year's annual meeting; provided, however, with respect to the annual meeting to be held in the calendar year 2003, the Shareholder Notice must be so delivered or mailed and so received on or before May 1, 2003; provided further, however, if and only if the annual meeting is not scheduled to be held within a period that commences thirty (30) days before the first anniversary date of the annual meeting for the preceding year and ends thirty (30) days after such anniversary date (an annual meeting date outside such period being referred to herein as an "Other Annual Meeting Date"), such Shareholder Notice must be given in the manner provided herein by the later of the close of business on (i) the date forty-five (45) days prior to such Other Annual Meeting Date or (ii) the tenth (10/th/) business day following the date such Other Annual Meeting Date is first publicly announced or disclosed.

Any Shareholder desiring to nominate any person or persons (as the case may be) for election as a Trustee or Trustees of the Trust shall deliver, as part of such Shareholder Notice: (i) a statement in writing setting forth (A) the name, age, date of birth, business address,

-8-

residence address and nationality of the person or persons to be nominated; (B) the class or series and number of all Shares of the Trust owned of record or beneficially by each such person or persons, as reported to such Shareholder by such nominee(s); (C) any other information regarding each such person required by paragraphs (a), (d), (e) and (f) of Item 401 of Regulation S-K or paragraph
(b) of Item 22 of Rule 14a-101 (Schedule 14A) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), adopted by the Securities and Exchange Commission (or the corresponding provisions of any regulation or rule subsequently adopted by the Securities and Exchange Commission or any successor agency applicable to the Trust); (D) any other information regarding the person or persons to be nominated that would be required to be disclosed in a proxy statement or other filings required to be made in connection with solicitation of proxies for election of Trustees or directors pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder; and (E) whether such Shareholder believes any nominee is or will be an "interested person" of the Trust (as defined in the Investment Company Act of 1940, as amended) and, if not an "interested person," information regarding each nominee that will be sufficient for the Trust to make such determination; and (ii) the written and signed consent of the person or persons to be nominated to be named as nominees and to serve as Trustees if elected. In addition, the Trustees may require any proposed nominee to furnish such other information as they may reasonably require or deem necessary to determine the eligibility of such proposed nominee to serve as a Trustee. Any Shareholder Notice required by this
Section 10.6(c) in respect of a proposal to fix the number of Trustees shall also set forth a description of and the text of the proposal, which description and text shall state a fixed number of Trustees that otherwise complies with applicable law, these Bylaws and the Declaration of Trust.

Without limiting the foregoing, any Shareholder who gives a Shareholder Notice of any matter proposed to be brought before a Shareholder meeting (whether or not involving nominees for Trustees) shall deliver, as part of such Shareholder Notice: (i) the description of and text of the proposal to be presented; (ii) a brief written statement of the reasons why such Shareholder favors the proposal; (iii) such Shareholder's name and address as they appear on the Trust's books; (iv) any other information relating to the Shareholder that would be required to be disclosed in a proxy statement or other filings required to be made in connection with the solicitation of proxies with respect to the matter(s) proposed pursuant to Section 14 of the Exchange Act and the rules and regulations promulgated thereunder; (v) the class or series and number of all Shares of the Trust owned beneficially and of record by such Shareholder; (vi) any material interest of such Shareholder in the matter proposed (other than as a Shareholder); (vii) a representation that the Shareholder intends to appear in person or by proxy at the Shareholder meeting to act on the matter(s) proposed;
(viii) if the proposal involves nominee(s) for Trustees, a description of all arrangements or understandings between the Shareholder and each proposed nominee and any other person or persons (including their names) pursuant to which the nomination(s) are to be made by the Shareholder; and (ix) in the case of a Beneficial Owner, evidence establishing such Beneficial Owner's indirect ownership of, and entitlement to vote, Shares at the meeting of Shareholders. As used in this Section 10.6, Shares "beneficially owned" shall mean all Shares which such person is deemed to beneficially own pursuant to Rules 13d-3 and 13d-5 under the Exchange Act.

-9-

(d) For any matter to be properly before any special meeting, the matter must be specified in the notice of meeting given by or at the direction of a majority of the Trustees and a majority of the Continuing Trustees pursuant to
Section 10.2 of these Bylaws. In the event the Trust calls a special meeting for the purpose of electing one or more Trustees, any Shareholder may nominate a person or persons (as the case may be) for election to such position(s) as specified in the Trust's notice of meeting if and only if the Shareholder provides a notice containing the information required in the Shareholder Notice to the Secretary required with respect to annual meetings by Section 10.6(c) hereof, and such notice is delivered to or mailed and received at the principal executive office of the Trust not later than the close of business on the tenth (10/th/) day following the day on which the date of the special meeting and of the nominees proposed by the Trustees to be elected at such meeting are publicly announced or disclosed.

(e) For purposes of this Section 10.6, a matter shall be deemed to have been "publicly announced or disclosed" if such matter is disclosed in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service, in a document publicly filed by the Trust with the Securities and Exchange Commission, or in a Web site accessible to the public maintained by the Trust or by its investment adviser or an affiliate of such investment adviser with respect to the Trust.

(f) In no event shall an adjournment or postponement (or a public announcement thereof) of a meeting of Shareholders commence a new time period (or extend any time period) for the giving of notice as provided in this Section 10.6.

(g) The person presiding at any meeting of Shareholders, in addition to making any other determinations that may be appropriate to the conduct of the meeting, shall have the power and duty to (i) determine whether a nomination or proposal of other matters to be brought before a meeting and notice thereof have been duly made and given in the manner provided in this Section 10.6 and elsewhere in these Bylaws and the Declaration of Trust and (ii) if not so made or given, to direct and declare at the meeting that such nomination and/or such other matters shall be disregarded and shall not be considered. Any determination by the person presiding shall be binding on all parties absent manifest error.

(h) Notwithstanding anything to the contrary in this Section 10.6 or otherwise in these Bylaws, unless required by federal law, no matter shall be considered at or brought before any annual or special meeting unless such matter has been approved for these purposes by a majority of the Continuing Trustees and, in particular, no Beneficial Owner shall have any rights as a Shareholder except as may be required by federal law. Furthermore, nothing in this Section 10.6 shall be construed as creating any implication or presumption as to the requirements of federal law.

/1/ If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of AAA- will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings of BB- will be used). If a security is not rated by any Rating Agency, the Trust will use the percentage set forth under "Not Rated or Below BBB" in this table.

The Fitch Discount Factors presented in the immediately preceding table apply to Debt Securities that are Performing and have a Market Value determined by a Pricing Service or an Approved Price. The Fitch Discount Factor noted in the table above for a Debt Security not rated or rated below BB by Fitch Ratings shall apply to any non-Performing Debt Security with a price equal to or greater than $0.20. If a Debt Security does not have a Market Value determined by a Pricing Service or an Approved Price, a rating one rating category below the actual rating on the Debt Security will be used (e.g., where the actual rating is A-, the rating for Debt Securities rated BBB- will be used). The Fitch Discount Factor for a Debt Security issued by a limited partnership that is not a Rule 144A Security shall be the Discount Factor determined in accordance with the table set forth above multiplied by 105%.

The Fitch Discount Factors presented in the immediately preceding table will also apply to (i) interest rate swaps and caps, whereby the rating of the counterparty to the swap or cap will be the rating used to determine the Fitch Discount Factor in the table; and (ii) TRACERs, whereby the ratings in the table will be applied to the underlying

-16-

securities and the Market Value of each underlying security will be its proportionate amount of the Market Value of the TRACER. The Fitch Discount Factors presented in the immediately preceding table will also apply to corporate obligations backed by a guaranty, a letter of credit or insurance issued by a third party. If the third-party credit rating is the basis for the rating on the obligation, then the rating on the third party will be used to determine the Fitch Discount Factor in the table. The Fitch Discount Factors presented in the immediately preceding table will also apply to preferred trust certificates, the rating on which will be determined by the underlying debt instruments in the trust, unless such preferred trust certificates are determined by Fitch Ratings to qualify for a traditional equity discount factor, in which case the Fitch Discount Factor shall be 370%.

Not rated or below Investment Grade DRD Preferred .................               200%/1/


/1/ If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings 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 rating by Fitch Rating of AAA- will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings of BB- will be used). If a security is not rated by any Rating Agency, the Fund will use the percentage set forth under "Not rated or below Investment Grade DRD Preferred" in this table.

(iii) Short-term instruments: The Fitch Discount Factor applied to short-term portfolio securities, including without limitation Debt Securities with terms to maturity of one year or less, Short Term Money Market Instruments and municipal debt obligations with terms to maturity within the Fitch Exposure Period, 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 neither mature nor have a demand feature exercisable at par within the Fitch Exposure Period; and (C) 125%, so long as such portfolio securities neither mature within the Fitch Exposure Period nor have a demand feature at par.

The Fitch Discount Factor applied to convertible securities which have conversion premiums of greater than 100% will be (a) 152% for investment grade convertible securities and (b) 179% for below investment grade convertible securities so long as such convertible securities do not have a yield to maturity or yield to worst of greater than 15.00% above the corresponding Treasury curve.

The Fitch Discount Factor applied to convertible securities which have a yield to maturity or yield to worst of greater than 15.00% above the corresponding Treasury curve will be 370%.

If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of AAA will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings 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.

If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of AAA will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings 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.

(x) Municipal debt obligations: The Fitch Discount Factor applied to municipal debt obligations will be the percentage determined by reference to the table set forth below:

                                 Fitch Rating Category

/1/ Municipal debt obligations rated by Fitch Ratings which do not mature or have a demand feature at par exercisable in 30 days and which do not have a long-term rating.
/2/ If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of AAA- will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings 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.

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 Ratings or the equivalent by another Rating Agency and such agreement has a term of 30 days or less; otherwise the Discounted Value of such purchased asset will constitute a Fitch Eligible Asset.

Notwithstanding the foregoing, an asset will not be considered a Fitch Eligible Asset to the extent that it has been irrevocably deposited for the payment of (i)(A) through (i)(E) under the definition of Preferred Shares Basic Maintenance Amount or to the extent it is subject to any Liens, except for (A) Liens which are being contested in good faith by appropriate proceedings

If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of BBB+ will be used). If a security is not rated by Fitch Ratings 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 rating by Fitch Ratings of AAA- will be used, and where the only rating on a security is a Moody's rating of Ba3, a rating by Fitch Ratings of BB- will be used).

(iv) "Fitch Loan Category D" means Bank Loans not described in any of the foregoing categories.

Securities for which quotations are not readily available shall be valued at fair value as determined by a Pricing Service using methods which include consideration of: yields or prices of securities of comparable quality, type of issue, coupon, maturity and rating; indications as to value from dealers; and general market conditions. A Pricing Service may employ electronic data processing techniques and/or a matrix system to determine valuations. In the event a Pricing Service is unable to value a security, the security shall be valued at the lower of two bid quotations obtained by the Trust from dealers who are members of the National Association of Securities Dealers, Inc. and who make a market in the security, at least one of which shall be in writing. If two bid quotations are not readily available for any securities, such securities shall be valued in good faith at fair value pursuant to procedures approved by the Board of Trustees of the Trust. Futures contracts and options are valued at the closing prices for such instruments established by the exchange or board of trade on which they are traded, or if market quotations are not readily available, are valued at fair value in good faith pursuant to procedures approved

/1/ Unless conclusions regarding liquidity risk as well as estimates of both the probability and severity of default for the Trust's assets can be derived from other sources as well as combined with a number of sources as presented by the Trust to Moody's, securities rated below B by Moody's and unrated securities, which are securities rated by neither Moody's, S&P nor Fitch Ratings, are limited to 10% of Moody's Eligible Assets. If a corporate debt security is unrated by Moody's, S&P and Fitch Ratings, the Trust will use the percentage set forth under "Below B and Unrated" in this table. Ratings assigned by S&P or Fitch Ratings are generally accepted by Moody's at face value. However, adjustments to face value may be made to particular categories of credits for which the rating by S&P and/or Fitch Ratings does not seem to approximate a Moody's rating equivalent.

The Moody's Discount Factors presented in the immediately preceding table will also apply to Moody's Eligible Assets that are FHLB, FNMA and FFCB Debentures and to rated TRACERs and TRAINs, whereby the ratings in the table will be applied to the underlying securities and the Market Value of each underlying security will be its proportionate amount of the Market Value of the TRACER or TRAIN, provided that the Moody's Discount Factors determined from the table shall be multiplied by a factor of 120% for purposes of calculating the Discounted Value of TRAINs. The Moody's

-28-

(b) The foregoing definitions of Accountant's Confirmation, Closing Transactions, Debt Securities, Deposit Securities, Discounted Value, Fitch Discount Factor, Fitch Eligible Assets, Fitch Exposure Period, Fitch Hedging Transactions, Fitch Industry Classifications, Forward Commitment, Independent Accountant, Market Value, Maximum Applicable Rate, Moody's Advance Rate, Moody's Discount Factor, Moody's Eligible Assets, Moody's Exposure Period, Moody's Hedging Transactions, Moody's Industry Classification, Moody's Loan Category, 1940 Act Cure Date, 1940 Act Preferred Shares Asset Coverage, Preferred Shares Basic Maintenance Amount, Preferred Shares Basic Maintenance Cure Date, Preferred Shares Basic Maintenance Report, Short Term Money Market Instruments, Treasury Bonds, Valuation Date and Volatility Factor (and any terms defined within such definitions) have been determined by the Board of Trustees of the Trust in order to obtain a rating of "AAA" from Fitch Ratings and a rating of "Aaa" from Moody's on the Preferred Shares on their Date of Original Issue; and the Board of Trustees of the Trust shall have the authority, without shareholder approval, to amend, alter or repeal from time to time the foregoing definitions (and any terms defined within such definitions) and the restrictions and guidelines set forth thereunder if Fitch Ratings, Moody's or any Substitute Rating Agency advises the Trust in writing that such amendment, alteration or repeal will not adversely affect its then current rating on the Preferred Shares.

11.2 Dividends. (a) The Holders of a particular series of Preferred Shares shall be entitled to receive, when, as and if declared by the Board of Trustees of the Trust, out of funds legally available therefor, cumulative dividends each consisting of cash at the Applicable Rate and no more, payable on the respective dates set forth below. Dividends on the shares of each series of Preferred Shares so declared and payable shall be paid in preference to and in priority over any dividends declared and payable on the Common Shares.

(b) (i) Cash dividends on shares of each series of Preferred Shares shall accumulate from the Date of Original Issue and shall be payable, when, as and if declared by the Board of Trustees of the Trust, out of funds legally available therefor, commencing on the Initial Dividend Payment Date. Following the Initial Dividend Payment Date for a series of Preferred Shares, dividends on that series of Preferred Shares will be payable, at the option of the Trust, either (i) with respect to any 7-Day Dividend Period and any Short Term Dividend Period of 35 or fewer days, on the day next succeeding the last day thereof, or
(ii) with respect to any Short Term

-48-

Dividend Period of more than 35 days and with respect to any Long Term Dividend Period, monthly on the first Business Day of each calendar month during such Short Term Dividend Period or Long Term Dividend Period and on the day next succeeding the last day thereof (each such date referred to in clause (i) or
(ii) being herein referred to as a "Normal Dividend Payment Date"), except that if such Normal Dividend Payment Date is not a Business Day, then the Dividend Payment Date shall be the first Business Day next succeeding such Normal Dividend Payment Date. Although any particular Dividend Payment Date may not occur on the originally scheduled date because of the exceptions discussed above, the next succeeding Dividend Payment Date, subject to such exceptions, will occur on the next following originally scheduled date. If for any reason a Dividend Period for a series of Preferred Shares is scheduled to begin on the same day and end on the same day as a Dividend Period for another series of Preferred Shares, then the last day of such Dividend Period for such other series of Preferred Shares shall be the second Business Day next succeeding such scheduled day unless the Trust obtains the opinion of tax counsel referred to in this paragraph. Subject to the limitation in the next sentence, if for any reason a Dividend Payment Date cannot be fixed as described above, then the Board of Trustees of the Trust shall fix the Dividend Payment Date. However, no Dividend Period of any series of Preferred Shares shall be co-extensive with any Dividend Period of any other series of Preferred Shares unless the Trust has received an opinion of tax counsel that having such co-extensive periods will not affect the deductibility, for federal income tax purposes, of dividends paid on the different series of Preferred Shares. The Board of Trustees of the Trust before authorizing a dividend may change a Dividend Payment Date if such change does not adversely affect the contract rights of the Holders of Preferred Shares set forth in the Declaration of Trust or the Bylaws. The Initial Dividend Period, 7-Day Dividend Periods and Special Dividend Periods with respect to a series of Preferred Shares are hereinafter sometimes referred to as "Dividend Periods." Each dividend payment date determined as provided above is hereinafter referred to as a "Dividend Payment Date."

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

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

-49-

For a series of Preferred Shares, the Applicable Rate for such series for each Dividend Period commencing during a Non-Payment Period shall be equal to the Non-Payment Period Rate; and each Dividend Period, commencing after the first day of and during, but not after the end of, a Non-Payment Period shall be a 7-Day Dividend Period. Except in the case of the willful failure of the Trust to pay a dividend on a Dividend Payment Date or to redeem any Preferred Shares on the date set for such redemption, any amount of any dividend due on any Dividend Payment Date (if, prior to the close of business on the second Business Day preceding such Dividend Payment Date, the Trust has declared such dividend payable on such Dividend Payment Date to the Holders of such Preferred Shares as of 12:00 noon, New York City time, on the Business Day preceding such Dividend Payment Date) or redemption price with respect to any Preferred Shares not paid to such Holders when due may be paid to such Holders in the same form of funds by 12:00 noon, New York City time, on any of the first three Business Days after such Dividend Payment Date or due date, as the case may be, provided that such amount is accompanied by a late charge calculated for such period of non-payment at the Non-Payment Period Rate applied to the amount of such non-payment based on the actual number of days comprising such period (excluding any days that would have been Business Days but for the occurrence of any unforeseen event or unforeseen events that caused such days not to be Business Days) divided by 365, and in such case such period shall not constitute a Non-Payment Period; provided, however, that the Trust shall not be required to pay any late charge if it declares a dividend on the Dividend Payment Date or the Business Day immediately preceding such Dividend Payment Date in accordance with clause (i) of the definition of "Non-Payment Period" and deposits payment for such dividend as contemplated by clause (ii)(A) of the definition of "Non-Payment Period" on or before the second Business Day succeeding the day on which the dividend was declared. In the case of a willful failure of the Trust to pay a dividend on a Dividend Payment Date or to redeem any Preferred Shares on the date set for such redemption, the preceding sentence shall not apply and the Applicable Rate for the Dividend Period commencing during the Non-Payment Period resulting from such failure shall be the Non-Payment Period Rate. For the purposes of the foregoing, payment to a person in same-day funds on any Business Day at any time shall be considered equivalent to payment to such person in New York Clearing House (next-day) funds at the same time on the preceding Business Day, and any payment made after 12:00 noon, New York City time, on any Business Day shall be considered to have been made instead in the same form of funds and to the same person before 12:00 noon, New York City time, on the next Business Day.

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

-50-

be 360, multiplying the amount so obtained by $25,000, and rounding the amount so obtained to the nearest cent.

(iii) The Trust may, at its sole option and to the extent permitted by law, by telephonic and written notice (a "Request for Special Dividend Period") to the Auction Agent and to each Broker-Dealer, request that the next succeeding Dividend Period for a series of Preferred Shares be a number of days (other than seven), evenly divisible by seven and not fewer than fourteen nor more than 364 in the case of a Short Term Dividend Period or one whole year or more but not greater than five years in the case of a Long Term Dividend Period, specified in such notice, provided that the Trust may not give a Request for Special Dividend Period for a Dividend Period of greater than 28 days (and any such request shall be null and void) unless, for any Auction occurring after the initial Auction, Sufficient Clearing Bids were made in the last occurring Auction and unless full cumulative dividends and any amounts due with respect to redemptions have been paid in full. Such Request for Special Dividend Period, in the case of a Short Term Dividend Period, shall be given on or prior to the second Business Day but not more than seven Business Days prior to an Auction Date for a series of Preferred Shares and, in the case of a Long Term Dividend Period, shall be given on or prior to the second Business Day but not more than 28 days prior to an Auction Date for a series of Preferred Shares. Upon receiving such Request for Special Dividend Period, the Broker-Dealer(s) shall jointly determine the Optional Redemption Price of the Preferred Shares during such Special Dividend Period and the Specific Redemption Provisions and shall give the Trust and the Auction Agent written notice (a "Response") of such determination by no later than the second Business Day prior to such Auction Date. In making such determination the Broker-Dealer(s) will consider (1) existing short-term and long-term market rates and indices of such short-term and long-term rates, (2) existing market supply and demand for short-term and long-term securities, (3) existing yield curves for short-term and long-term securities comparable to the Preferred Shares, (4) industry and financial conditions which may affect the Preferred Shares, (5) the investment objectives of the Trust, and (6) the Dividend Periods and dividend rates at which current and potential beneficial holders of the Preferred Shares would remain or become beneficial holders. After providing the Request for Special Dividend Period to the Auction Agent and each Broker-Dealer as set forth above, the Trust may by no later than the second Business Day prior to such Auction Date give a notice (a "Notice of Special Dividend Period") to the Auction Agent, the Securities Depository and each Broker-Dealer which notice will specify (i) the duration of the Special Dividend Period, (ii) the Optional Redemption Price as specified in the related Response and (iii) the Specific Redemption Provisions, if any, as specified in the related Response. The Trust also shall provide a copy of such Notice of Special Dividend Period to Fitch Ratings, Moody's and any Substitute Rating Agency. The Trust shall not give a Notice of Special Dividend Period and, if the Trust has given a Notice of Special Dividend Period, the Trust is required to give telephonic and written notice of its revocation (a "Notice of Revocation") to the Auction Agent, each Broker-Dealer, and the Securities Depository on or prior to the Business Day prior to the relevant Auction Date if (x) either the 1940 Act Preferred Shares Asset Coverage is not satisfied or the Trust shall fail to maintain Fitch Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount, on each of the two Valuation Dates immediately preceding the Business Day prior to the relevant Auction Date on an actual basis and on a pro forma basis giving effect to the proposed Special Dividend Period (using as a pro forma dividend rate with respect to such Special Dividend

-51-

Period the dividend rate which the Broker-Dealers shall advise the Trust is an approximately equal rate for securities similar to the Preferred Shares with an equal dividend period) or (y) sufficient funds for the payment of dividends payable on the immediately succeeding Dividend Payment Date have not been irrevocably deposited with the Auction Agent by the close of business on the third Business Day preceding the Auction Date immediately preceding such Dividend Payment Date. The Trust also shall provide a copy of such Notice of Revocation to Fitch Ratings, Moody's and any Substitute Rating Agency. If the Trust is prohibited from giving a Notice of Special Dividend Period as a result of any of the factors enumerated in clause (x) or (y) above or if the Trust gives a Notice of Revocation with respect to a Notice of Special Dividend Period for any series of Preferred Shares, the next succeeding Dividend Period will be a 7-Day Dividend Period. In addition, in the event Sufficient Clearing Bids are not made in an Auction, or if an Auction is not held for any reason, such next succeeding Dividend Period will be a 7-Day Dividend Period and the Trust may not again give a Notice of Special Dividend Period for the Preferred Shares (and any such attempted notice shall be null and void) until Sufficient Clearing Bids have been made in an Auction with respect to a 7-Day Dividend Period. If an Auction is not held because an unforeseen event or unforeseen events cause a day that otherwise would have been a Dividend Payment Date or an Auction Date not to be a Business Day, then the length of the Dividend Period relating to such Dividend Payment Date shall be extended by seven days (or a multiple thereof if necessary because of such unforeseen event or events) (an "Extension Period"), the Applicable Rate for such Extension Period shall be the Applicable Rate for the Dividend Period so extended and the Dividend Payment Date for such Dividend Period shall be the first Business Day next succeeding the end of such Extension Period.

(d) (i) Holders shall not be entitled to any dividends, whether payable in cash, property or Preferred Shares, in excess of full cumulative dividends as herein provided. Except for the late charge payable pursuant to Section 11.2(c)(i) hereof, no interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment on the Preferred Shares that may be in arrears.

(ii) For so long as any Preferred Share is Outstanding, the Trust shall not declare, pay or set apart for payment any dividend or other distribution (other than a dividend or distribution paid in shares of, or options, warrants or rights to subscribe for or purchase, Common Shares or other shares of beneficial interest, if any, ranking junior to the Preferred Shares as to dividends or upon liquidation) in respect of the Common Shares or any other shares of beneficial interest of the Trust ranking junior to or on a parity with the Preferred Shares as to dividends or upon liquidation, or call for redemption, redeem, purchase or otherwise acquire for consideration any Common Shares or any other such junior shares (except by conversion into or exchange for shares of the Trust ranking junior to the Preferred Shares as to dividends and upon liquidation) or any other such Parity Shares (except by conversion into or exchange for stock of the Trust ranking junior to or on a parity with the Preferred Shares as to dividends and upon liquidation), unless (A) immediately after such transaction, the Trust shall have Fitch Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount and the Trust shall maintain the 1940 Act Preferred Shares Asset Coverage, (B) full cumulative dividends on Preferred Shares due on or prior to the date of the transaction have been declared and paid or shall have been declared and sufficient

-52-

funds for the payment thereof deposited with the Auction Agent and (C) the Trust has redeemed the full number of Preferred Shares required to be redeemed by any provision for mandatory redemption contained herein.

(e) Each dividend shall consist of cash at the Applicable Rate.

(f) No fractional Preferred Shares shall be issued.

(g) Solely for purposes of the proviso in clause (i) under the definition of "Non-Payment Period," the second parenthetical in the second sentence of the second paragraph of Section 11.2(c)(i) of these Bylaws and the last sentence of
Section 11.2(c)(iii) of these Bylaws, any day on which banks in New York City generally are closed, for any reason, while the New York Stock Exchange remains open for trading and any day which otherwise would be a Business Day as defined in these Bylaws on which the Auction Agent is closed for business, for any reason, shall be considered a day which is not a Business Day.

11.3 Liquidation Rights. Upon any liquidation, dissolution or winding up of the Trust, whether voluntary or involuntary, the Holders shall be entitled to receive, out of the assets of the Trust available for distribution to shareholders, before any distribution or payment is made upon any Common Shares or any other shares of beneficial interest ranking junior in right of payment upon liquidation to the Preferred Shares, the sum of $25,000 per share plus accumulated but unpaid dividends (whether or not earned or declared) thereon to the date of distribution, and after such payment the Holders will be entitled to no other payments. If upon any liquidation, dissolution or winding up of the Trust, the amounts payable with respect to the Preferred Shares and any other Outstanding class or series of preferred shares of beneficial interest of the Trust ranking on a parity with the Preferred Shares as to payment upon liquidation are not paid in full, the Holders and the holders of such other class or series will share ratably in any such distribution of assets in proportion to the respective preferential amounts to which they are entitled. After payment of the full amount of the liquidating distribution to which they are entitled, the Holders will not be entitled to any further participation in any distribution of assets by the Trust. A consolidation, merger or statutory share exchange of the Trust with or into any other Trust or entity or a sale, whether for cash, shares of stock, securities or properties, of all or substantially all or any part of the assets of the Trust shall not be deemed or construed to be a liquidation, dissolution or winding up of the Trust.

11.4 Redemption. (a) Preferred Shares shall be redeemable by the Trust as provided below:

(i) To the extent permitted under the 1940 Act and Massachusetts law, upon giving a Notice of Redemption, the Trust at its option may redeem shares of any series of Preferred Shares, in whole or in part, out of funds legally available therefor, at the Optional Redemption Price per share, on any Dividend Payment Date; provided that no Preferred Share may be redeemed at the option of the Trust during (A) the Initial Dividend Period with respect to a series of shares or (B) a Non-Call Period to which such share is subject.

-53-

(ii) The Trust shall redeem, out of funds legally available therefor, at the Mandatory Redemption Price per share, Preferred Shares to the extent permitted under the 1940 Act and Massachusetts law, on a date fixed by the Board of Trustees of the Trust, if the Trust fails to maintain Fitch Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount as provided in
Section 11.7(a) or to satisfy the 1940 Act Preferred Shares Asset Coverage as provided in Section 11.6 and such failure is not cured on or before the Preferred Shares Basic Maintenance Cure Date or the 1940 Act Cure Date (herein collectively referred to as a "Cure Date"), as the case may be. The number of Preferred Shares to be redeemed shall be equal to the lesser of (i) the minimum number of Preferred Shares the redemption of which, if deemed to have occurred immediately prior to the opening of business on the Cure Date, together with all other preferred shares of beneficial interest of the Trust subject to redemption or retirement, would result in the Trust having Fitch Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or satisfaction of the 1940 Act Preferred Shares Asset Coverage, as the case may be, on such Cure Date (provided that, if there is no such minimum number of Preferred Shares and other preferred shares of beneficial interest of the Trust the redemption of which would have such result, all Preferred Shares and other preferred shares of beneficial interest of the Trust then Outstanding shall be redeemed), and (ii) the maximum number of Preferred Shares, together with all other preferred shares of beneficial interest of the Trust subject to redemption or retirement, that can be redeemed out of funds expected to be legally available therefor on such redemption date. In determining the number of Preferred Shares required to be redeemed in accordance with the foregoing, the Trust shall allocate the number required to be redeemed which would result in the Trust having Fitch Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or satisfaction of the 1940 Act Preferred Shares Asset Coverage, as the case may be, pro rata among Preferred Shares of all series and other preferred shares of beneficial interest of the Trust subject to redemption pursuant to provisions similar to those contained in this Section 11.4(a)(ii); provided that Preferred Shares which may not be redeemed at the option of the Trust due to the designation of a Non-Call Period applicable to such shares (A) will be subject to mandatory redemption only to the extent that other shares are not available to satisfy the number of shares required to be redeemed and (B) will be selected for redemption in an ascending order of outstanding number of days remaining in the Non-Call Period (with shares with the lowest number of days to be redeemed first) and by lot in the event of shares having an equal number of days remaining in such Non-Call Period. The Trust shall effect such redemption on a Business Day which is not later than 35 days after such Cure Date, except that if the Trust does not have funds legally available for the redemption of all of the required number of Preferred Shares and other preferred shares of beneficial interest of the Trust which are subject to mandatory redemption or the Trust otherwise is unable to effect such redemption on or prior to 35 days after such Cure Date, the Trust shall redeem those Preferred Shares which it is unable to redeem on the earliest practicable date on which it is able to effect such redemption out of funds legally available therefor.

(b) Notwithstanding any other provision of this Section 11.4, no Preferred Shares may be redeemed pursuant to Section 11.4(a)(i) of these Bylaws unless (i) all dividends in arrears on all remaining outstanding Parity Shares shall have been or are being contemporaneously paid or

-54-

declared and set apart for payment, and (ii) redemption thereof would result in the Trust's failure to maintain Fitch Eligible Assets or Moody's Eligible Assets with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount. In the event that less than all the outstanding shares of a series of Preferred Shares are to be redeemed and there is more than one Holder, the shares of that series of Preferred Shares to be redeemed shall be selected by lot or such other method as the Trust shall deem fair and equitable.

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

If the Notice of Redemption shall have been given as aforesaid and, concurrently or thereafter, the Trust shall have deposited in trust with the Auction Agent, or segregated in an account at the Trust's custodian bank for the benefit of the Auction Agent, Deposit Securities (with a right of substitution) having an aggregate Discounted Value equal to the redemption payment for the Preferred Shares as to which such Notice of Redemption has been given with irrevocable instructions and authority to pay the redemption price to the Holders of such shares, then upon the date of such deposit or, if no such deposit is made, then upon such date fixed for redemption (unless the Trust shall default in making the redemption payment), all rights (including without limitation voting rights) of the Holders of such shares as shareholders of the Trust by reason of the ownership of such shares will cease and terminate (except their right to receive the redemption price in respect thereof, but without interest), and such shares shall no longer be deemed Outstanding. The Trust shall be entitled to receive, from time to time, from the Auction Agent the interest, if any, on such Deposit Securities deposited with it and the Holders of any shares so redeemed shall have no claim to any of such interest. In case the Holder of any shares so called for redemption shall not claim the redemption payment for his shares within one year after the date of redemption, the Auction Agent shall, upon demand, pay over to the Trust such amount remaining on deposit and the Auction Agent shall thereupon be relieved of all responsibility to the Holder of such shares called for redemption and such Holder thereafter shall look only to the Trust for the redemption payment.

11.5 Voting Rights. (a) General. Except as otherwise provided in the Declaration of Trust or Bylaws or as otherwise required by applicable law, each Holder of Preferred Shares shall be entitled to one vote for each share held on each matter submitted to a vote of shareholders of the Trust, and the holders of Outstanding preferred shares of beneficial interest of the Trust, including Preferred Shares, and of Common Shares shall vote together as a single class; provided that, at any meeting of the shareholders of the Trust held for the election of trustees, the holders of Outstanding preferred shares of beneficial interest of the Trust, including

-55-

Preferred Shares, shall be entitled, as a class, to the exclusion of the holders of all other securities and classes of shares of beneficial interest of the Trust, to elect two trustees of the Trust. Subject to Section 11.5(b) hereof, the holders of shares of beneficial interest of the Trust, including the holders of preferred shares of beneficial interest of the Trust, including Preferred Shares, voting as a single class, shall elect the balance of the trustees.

(b) Right to Elect Majority of Board of Trustees. Except as otherwise required by law, during any period in which any one or more of the conditions described below shall exist (such period being referred to herein as a "Voting Period"), the number of trustees constituting the Board of Trustees of the Trust shall be automatically increased by the smallest number that, when added to the two trustees elected exclusively by the holders of preferred shares of beneficial interest of the Trust, would constitute a majority of the Board of Trustees of the Trust as so increased by such smallest number; and the holders of preferred shares of beneficial interest of the Trust shall be entitled, voting separately as one class (to the exclusion of the holders of all other securities and classes of shares of beneficial interest of the Trust), to elect such smallest number of additional trustees, together with the two trustees that such holders are in any event entitled to elect.

A Voting Period shall commence:

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

(ii) if at any time holders of any preferred shares of beneficial interest of the Trust, including the holders of Preferred Shares, are entitled to elect a majority of the trustees of the Trust under the 1940 Act.

Upon the termination of a Voting Period, the voting rights described in this Section 11.5(b) shall cease, subject always, however, to the revesting of such voting rights in the Holders upon the further occurrence of any of the events described in Section 11.5(b).

(c) Right to Vote with Respect to Certain Other Matters. So long as any Preferred Shares are outstanding, the Trust shall not, without the affirmative vote of the holders of a majority of the Preferred Shares Outstanding at the time, voting separately as one class: (i) authorize, create or issue any class or series of shares of beneficial interest ranking prior to the Preferred Shares or any other series of preferred shares of beneficial interest of the Trust with respect to payment of dividends or the distribution of assets on liquidation; provided, however, that no vote is required to authorize the issuance of another series of Preferred Shares or another class of preferred shares of beneficial interest of the Trust that is substantially identical in all respects to the Preferred Shares, or (ii) amend, alter or repeal the provisions of the Declaration of Trust or Bylaws, whether by merger, consolidation or otherwise, so as to adversely affect any of the contract rights expressly set forth in the Declaration of Trust or Bylaws of holders of Preferred Shares or any other preferred shares of beneficial interest of the Trust. To the extent

-56-

permitted under the 1940 Act, in the event shares of more than one series of Preferred Shares are outstanding, the Trust shall not approve any of the actions set forth in clause (i) or (ii) which adversely affects the contract rights expressly set forth in the Declaration of Trust or Bylaws of a Holder of a series of Preferred Shares differently than those of a Holder of any other series of Preferred Shares without the affirmative vote of the holders of at least a majority of the Preferred Shares of each series adversely affected and Outstanding at such time (each such adversely affected series voting separately as a class). Unless a higher percentage is provided for under the Declaration of Trust or these Bylaws, the affirmative vote of the holders of a majority of the outstanding preferred shares of beneficial interest of the Trust, including Preferred Shares, voting together as a single class, will be required to approve any plan of reorganization (including bankruptcy proceedings) adversely affecting such shares or any action requiring a vote of security holders under
Section 13(a) of the 1940 Act. To the extent permitted under the 1940 Act, in the event shares of more than one series of Preferred Shares are outstanding, with respect to any action requiring Shareholder approval pursuant to the operation of Section 2 or Section 3 of Article V of the Declaration of Trust, the affirmative vote of at least seventy-five percent of the Preferred Shares of each series Outstanding at such time (each such series voting separately as a class) shall also be required. The class (and, where applicable, series) vote of holders of preferred shares of beneficial interest of the Trust, including Preferred Shares, described above will in each case be in addition to a separate vote of the requisite percentage of Common Shares and preferred shares of beneficial interest of the Trust, including Preferred Shares, voting together as a single class necessary to authorize the action in question.

(d) Voting Procedures.

(i) As soon as practicable after the accrual of any right of the holders of preferred shares of beneficial interest of the Trust to elect additional trustees as described in Section 11.5(b) above, the Trust shall call a special meeting of such holders and instruct the Auction Agent and any other registrar for preferred shares of beneficial interest of the Trust other than Preferred Shares to mail a notice of such special meeting to such holders, such meeting to be held not less than 10 nor more than 20 days after the date of mailing of such notice. If the Trust fails to send such notice to the Auction Agent and any other applicable registrar, or if the Trust does not call such a special meeting, it may be called by any such holder on like notice. The record date for determining the holders entitled to notice of and to vote at such special meeting shall be the close of business on the fifth Business Day preceding the day on which such notice is mailed. At any such special meeting and at each meeting held during a Voting Period 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 beneficial interest of the Trust), shall be entitled to elect the number of Trustees prescribed in Section 11.5(b) above. At any such meeting or adjournment thereof in the absence of a quorum, a majority of such holders present in person or by proxy shall have the power to adjourn the meeting without notice, other than by an announcement at the meeting, to a date not more than 120 days after the original record date.

(ii) Except as otherwise required by applicable law, for purposes of determining any rights of the Holders to vote on any matter or the number of shares required to constitute a quorum, whether such right is created by these Bylaws, by the other provisions of the

(a) So long as any Preferred Shares are outstanding and any Rating Agency so requires, the Trust shall maintain, on each Valuation Date, and shall verify to its satisfaction that it is maintaining on such Valuation Date, Fitch Eligible Assets and Moody's Eligible Assets each having an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount. Upon any failure to maintain the required Discounted Value, the Trust will use its best efforts to alter the composition of its portfolio to retain a Discounted Value of both Fitch Eligible Assets and Moody's Eligible Assets at least equal to the Preferred Shares Basic Maintenance Amount on or prior to the Preferred Shares Basic Maintenance Cure Date.

-58-

telecopy, telex or other electronic transcription thereof and on the same day the Trust mails to the recipient for delivery on the next Business Day the complete Preferred Shares Basic Maintenance Report. The Trust will deliver a Preferred Shares Basic Maintenance Report to each applicable Rating Agency on or before 5:00 p.m., New York City time, on the third Business Day after a Valuation Date on which the Trust cures its failure to maintain Eligible Assets of each applicable Rating Agency with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount or on which the Trust fails to maintain Eligible Assets of each applicable Rating Agency with an aggregate Discounted Value which exceeds the Preferred Shares Basic Maintenance Amount by 5% or more. The Trust will also deliver a Preferred Shares Basic Maintenance Report to the Auction Agent, Fitch Ratings and Moody's as of each Quarterly Valuation Date on or before the third Business Day after such date. Additionally, on or before 5:00 p.m., New York City time, on the third Business Day after the first day of a Special Dividend Period, the Trust will deliver a Preferred Shares Basic Maintenance Report to the Auction Agent, Fitch Ratings and Moody's. The Trust shall also provide Fitch Ratings or Moody's with a Preferred Shares Basic Maintenance Report when specifically requested by Fitch Ratings or Moody's, respectively.

(c) Within ten Business Days after the date of delivery of a Preferred Shares Basic Maintenance Report in accordance with Section 11.7(b) above relating to a Quarterly Valuation Date (except as described in the following sentence), the Independent Accountant will confirm in writing to the Auction Agent, Fitch Ratings and Moody's, (i) the mathematical accuracy of the calculations reflected in such Report (and in any other Preferred Shares Basic Maintenance Report, randomly selected by the Independent Accountant, that was delivered by the Trust during the quarter ending on such Quarterly Valuation Date), (ii) that, in such Report (and in such randomly selected Report), the Trust correctly determined the assets of the Trust which constitute Fitch Eligible Assets and Moody's Eligible Assets at such Quarterly Valuation Date in accordance with these Bylaws, (iii) that, in such Report (and in such randomly selected Report), the Trust determined whether the Trust had, at such Quarterly Valuation Date (and at the Valuation Date addressed in such randomly selected Report) in accordance with these Bylaws, Fitch Eligible Assets and Moody's Eligible Assets each with an aggregate Discounted Value at least equal to the Preferred Shares Basic Maintenance Amount, (iv) with respect to the S&P ratings on portfolio securities of the Trust, the issuer name, issue size and coupon rate, if any, listed in such Report, that the Independent Accountant has requested that S&P verify such information and the Independent Accountant shall provide a listing in its letter of any differences, (v) with respect to the Fitch Ratings' ratings on portfolio securities of the Trust, the issuer name, issue size and coupon rate, if any, listed in such Report, that such information has been verified by Fitch Ratings (in the event such information is not verified by Fitch Ratings, the Independent Accountant will inquire of Fitch Ratings what such information is, and provide a listing in its letter of any differences), (vi) with respect to the Moody's ratings on portfolio securities of the Trust, the issuer name, issue size and coupon rate, if any, listed in such Report, that such information has been verified by Moody's (in the event such information is not verified by Moody's, the Independent Accountant will inquire of Moody's what such information is, and provide a listing in its letter of any differences) and (vii) with respect to the bid or mean price (or such alternative permissible factor used in calculating the Market Value) provided by the custodian of the Trust's assets to the Trust for purposes of valuing securities in the Trust's portfolio, the Independent Accountant has traced the price used in such Report to the bid or mean

-59-

price listed in such Report as provided to the Trust and verified that such information agrees (in the event such information does not agree, the Independent Accountant will provide a listing in its letter of such differences) (such confirmation is herein called the "Accountant's Confirmation"). Notwithstanding the foregoing sentence, the Independent Accountant will provide the confirmation described in the foregoing sentence with respect to Preferred Shares Basic Maintenance Reports delivered pursuant to the third sentence of
Section 11.7(b) above only for such Preferred Share Basic Maintenance Reports relating to the last fiscal quarter of each fiscal year.

(d) Within ten Business Days after the date of delivery to the Auction Agent and any applicable Rating Agency of a Preferred Shares Basic Maintenance Report in accordance with Section 11.7(b) above relating to any Valuation Date on which the Trust failed to maintain Eligible Assets of such applicable Rating Agency with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount, and relating to the Preferred Shares Basic Maintenance Cure Date with respect to such failure, the Trust shall cause the Independent Accountant to provide to the Auction Agent and each applicable Rating Agency an Accountant's Confirmation as to such Preferred Shares Basic Maintenance Report.

(e) If any Accountant's Confirmation delivered pursuant to subparagraph (c) or (d) of this Section 11.7 shows that an error was made in the Preferred Shares Basic Maintenance Report for a particular Valuation Date for which such Accountant's Confirmation was required to be delivered, or shows that a lower aggregate Discounted Value for the aggregate of all Fitch Eligible Assets or Moody's Eligible Assets of the Trust was determined by the Independent Accountant, the calculation or determination made by such Independent Accountant shall be final and conclusive and shall be binding on the Trust, and the Trust shall accordingly amend and deliver the Preferred Shares Basic Maintenance Report to the Auction Agent and each applicable Rating Agency promptly following receipt by the Trust of such Accountant's Confirmation.

(f) Within five Business Day after the Date of Original Issue of the Preferred Shares, the Trust will complete and deliver to Moody's a Preferred Shares Basic Maintenance Report as of the close of business on such Date of Original Issue. Also, on or before 5:00 p.m., New York City time, on the first Business Day after Common Shares are repurchased by the Trust, the Trust will complete and deliver to Fitch Ratings and Moody's a Preferred Shares Basic Maintenance Report as of the close of business on such date that Common Shares are repurchased.

(i) the Trust will not engage in any Moody's Hedging Transaction based on any index approved by Moody's (other than transactions that terminate a futures contract or option held by the Trust by the Trust's taking the opposite position thereto ("Closing Transactions")) that would cause the Trust at the time of such transaction to own or have sold:

(A) outstanding financial futures contracts based on such index exceeding in number 10% of the average number of daily traded financial futures contracts based on such index in the 30 days preceding the time of effecting such transaction as reported by The Wall Street Journal; or

(ii) the Trust will not engage in any Moody's Hedging Transaction based on Treasury Bonds (other than Closing Transactions) that would cause the Trust at the time of such transaction to own or have sold:

(A) outstanding financial futures contracts based on Treasury Bonds with such contracts having an aggregate Market Value exceeding 20% of the aggregate Market Value of Moody's Eligible Assets owned by the Trust and rated Aa by Moody's (or, if not rated by Moody's but rated by S&P, rated AAA by S&P); or

(B) outstanding financial futures contracts based on Treasury Bonds with such contracts having an aggregate Market Value exceeding 80% of the aggregate Market Value of all portfolio securities of the Trust constituting Moody's Eligible Assets owned by the Trust (other than Moody's Eligible Assets already subject to a Moody's Hedging Transaction) and rated Baa or A by Moody's (or, if not rated by Moody's but rated by S&P, rated A or AA by S&P)

(for purposes of the foregoing clauses (i) and (ii), the Trust shall be deemed to own the number of financial futures contracts that underlie any outstanding options written by the Trust);

(iii) the Trust will engage in Closing Transactions to close out any outstanding financial futures contract based on any index approved by Moody's if the amount of open interest in such index as reported by The Wall Street Journal is less than an amount to be mutually determined by Moody's and the Trust;

(iv) the Trust will engage in a Closing Transaction to close out any outstanding financial futures contract by no later than the fifth Business Day of the month in which

-61-

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

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

(vi) the Trust (A) will not engage in options and futures transactions for leveraging or speculative purposes, except that an option or futures transaction shall not for these purposes be considered a leveraged position or speculative so long as the combination of the Trust's non-derivative positions, together with the relevant option or futures transaction, produces a synthetic investment position, or the same economic result, that could be achieved by an investment, consistent with the Trust's investment objectives and policies, in a security that is not an option or futures transaction, and (B) will not write any call options or sell any financial futures contracts for the purpose of hedging the anticipated purchase of an asset prior to completion of such purchase; and

(vii) while the Trust may use options and futures transactions for hedging and risk management purposes, it will not enter into an option or futures transaction unless, after giving effect thereto, the Trust would continue to have Moody's Eligible Assets with an aggregate Discounted Value equal to or greater than the Preferred Shares Basic Maintenance Amount.

(b) For purposes of determining whether the Trust has Moody's Eligible Assets with an aggregate Discounted Value that equals or exceeds the Preferred Shares Basic Maintenance Amount, the Discounted Value of Moody's Eligible Assets that the Trust is obligated to deliver or receive pursuant to an outstanding futures contract or option shall be as follows:

(i) assets subject to call options written by the Trust that are either exchange-traded and "readily reversible" or that expire within 49 days after the date as of which such valuation is made shall be valued at the lesser of (A) Discounted Value and (B) the exercise price of the call option written by the Trust;

(ii) assets subject to call options written by the Trust not meeting the requirements of clause (i) of this sentence shall have no value;

-62-

(v) where delivery may be made to the Trust with any security of a class of securities, the Trust shall assume that it will take delivery of the security with the lowest Discounted Value.

(c) For purposes of determining whether the Trust has Moody's Eligible Assets with an aggregate Discounted Value that equals or exceeds the Preferred Shares Basic Maintenance Amount, the following amounts shall be subtracted from the aggregate Discounted Value of the Moody's Eligible Assets held by the Trust to the extent the relevant asset is a Moody's Eligible Asset:

(i) 10% of the exercise price of a written call option;

(ii) the exercise price of any written put option;

(iii) where the Trust is the seller under a financial futures contract, 10% of the settlement price of the financial futures contract;

(d) For so long as any Preferred Shares are rated by Moody's, the Trust will not enter into any "Forward Commitment," herein defined as any contract to purchase securities for a fixed price at a future date beyond customary settlement time (other than such contracts that constitute Fitch Hedging Transactions or Moody's Hedging Transactions, as applicable), except that the Trust may enter into Forward Commitments subject to the following limitations:

(i) for each Forward Commitment, the Trust will maintain with its custodian (A) cash, cash equivalents or short-term, fixed-income securities rated P-1, MIG-1 or VMIG-1 by Moody's or A-1 by S&P and maturing in one year or less with a fair market value that equals or exceeds the amount by which the Trust's obligations under any Forward Commitments to which it is from time to time a party exceed obligations to the Trust arising from securities sales by the Trust that are scheduled to settle at a future date, or (B) long-term, fixed-income securities with a then current market value that equals or exceeds the amount by which the Trust's obligations under any Forward Commitments to which it is from time to time a party exceed obligations to the Trust arising from securities sales by the Trust that are scheduled to settle on a future date, or (C) a combination of assets described in (A) and (B) above that in the aggregate equals or exceeds the amount by which the Trust's obligations under any Forward Commitments to which it is from time to time a party exceed obligations to the Trust arising from securities sales by the Trust that are scheduled to settle on a future date; and

-63-

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

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

(e) For so long as any Preferred Shares are Outstanding and Fitch Ratings or Moody's or both is rating such shares, the Trust, unless it has received written confirmation from Fitch Ratings or Moody's or both, as applicable, that such action would not impair the rating then assigned to the Preferred Shares by Fitch Ratings or Moody's or both, as applicable, will not:

(i) borrow money except for the purpose of clearing transactions in portfolio securities (which borrowings under any circumstances shall be limited to an amount equal to 5% of the Market Value of the Trust's assets at the time of such borrowings and which borrowings shall be repaid within 60 days and not be extended or renewed and shall not cause the aggregate Discounted Value of Fitch Eligible Assets or Moody's Eligible Assets, as applicable, to be less than the Preferred Shares Basic Maintenance Amount);

(ii) engage in short sales of securities;

(iii) lend any securities;

(iv) issue any class or series of shares of beneficial interest ranking prior to or on a parity with the Preferred Shares with respect to the payment of dividends or the distribution of assets upon dissolution, liquidation or winding up of the Trust;

(i) assets subject to call options written by the Trust that are either exchange-traded and "readily reversible" or that expire within 49 days after the date as of which such valuation is made shall be valued at the lesser of (A) Discounted Value and (B) the exercise price of the call option written by the Trust;

(v) where delivery may be made to the Trust with any security of a class of securities, the Trust shall assume that it will take delivery of the security with the lowest Discounted Value.

(h) For purposes of determining whether the Trust has Fitch Eligible Assets with an aggregate Discounted Value that equals or exceeds the Preferred Shares Basic Maintenance Amount, the following amounts shall be subtracted from the aggregate Discounted Value of the Fitch Eligible Assets held by the Trust to the extent the relevant asset is a Fitch Eligible Asset:

(i) 10% of the exercise price of a written call option;

The Auction Agent will not round the applicable Reference Rate as part of its calculation of the Maximum Applicable Rate. The "Applicable Percentage" shall be the percentage determined based on the lower of the credit ratings assigned on such date by Moody's and Fitch Ratings as follows:

-67-

   Moody's                  Fitch                Applicable
Credit Rating           Credit Rating            Percentage

Baa3 to Baa1            BBB- to BBB+                250%
 Below Baa3              Below BBB-                 275%

The Applicable Percentage as so determined shall be further subject to upward but not downward adjustment in the discretion of the Board of Trustees of the Trust after consultation with the Broker-Dealers, provided that the Board of Trustees has received assurance from Moody's and Fitch Ratings and from any other Rating Agency then rating the Preferred Shares that such increase will not impair such Rating Agency's rating thereof, and further provided that immediately following any such increase the Trust would be in compliance with the Preferred Shares Basic Maintenance Amount. The Trust shall take all reasonable action necessary to enable Moody's and Fitch Ratings to provide a rating for each series of Preferred Shares. If Moody's or Fitch Ratings shall not make such a rating available, Citigroup Global Markets Inc. or its affiliates and successors, after consultation with the Trust, shall select another Rating Agency to act as a Substitute Rating Agency.

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

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

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

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

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

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

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

For the purposes hereof, the communication by a Beneficial Owner or Potential Beneficial Owner to a Broker-Dealer, or the communication by a Broker-Dealer acting for its own account to the Auction Agent, of information referred to in clause (A) or (B) of this
Section 11.10(b)(i) is hereinafter referred to as an "Order" and each Beneficial Owner and each Potential Beneficial Owner placing an Order, including a

-69-

Broker-Dealer acting in such capacity for its own account, is hereinafter referred to as a "Bidder"; an Order containing the information referred to in clause (A)(1) of this Section 11.10(b)(i) is hereinafter referred to as a "Hold Order"; an Order containing the information referred to in clause (A)(2) or (B) of this Section 11.10(b)(i) is hereinafter referred to as a "Bid"; and an Order containing the information referred to in clause (A)(3) of this
Section 11.10(b)(i) is hereinafter referred to as a "Sell Order." Inasmuch as a Broker-Dealer participates in an Auction as an Existing Holder or a Potential Holder only to represent the interests of a Beneficial Owner or Potential Beneficial Owner, whether it be its customers or itself, all discussion herein relating to the consequences of an Auction for Existing Holders and Potential Holders also applies to the underlying beneficial ownership interests represented.

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

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

(2) such number or a lesser number of Outstanding Preferred Shares to be determined as set forth in Section 11.10(e)(i)(D) if the Applicable Rate determined on such Auction Date shall be equal to the rate per annum specified therein; or

(3) a lesser number of Outstanding Preferred Shares to be determined as set forth in Section 11.10(e)(ii)(C) if such specified rate per annum shall be higher than the Maximum Applicable Rate and Sufficient Clearing Bids do not exist.

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

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

(2) such number or a lesser number of Outstanding Preferred Shares to be determined as set forth in Section 11.10(e)(ii)(C) if Sufficient Clearing Bids do not exist.

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

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

(2) such number or a lesser number of Outstanding Preferred Shares to be determined as set forth in Section 11.10(e)(i)(E) if the Applicable Rate

-70-

determined on such Auction Date shall be equal to the rate per annum specified therein.

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

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

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

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

(C) to the extent that such Bidder is a Beneficial Owner or an Existing Holder:

(1) the number of Outstanding Preferred Shares, if any, subject any Hold Order placed by such Beneficial Owner or Existing Holder;

(2) the number of Outstanding Preferred Shares, if any, subject to any Bid placed by such Beneficial Owner or Existing Holder and the rate per annum specified in such Bid; and

(3) the number of Outstanding Preferred Shares, if any, subject to any Sell Order placed by such Beneficial Owner or Existing Holder; and

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

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

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

-71-

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

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

(B) any Bids submitted on behalf of such Existing Holder shall be considered valid, in the ascending order of their respective rates per annum if more than one Bid is submitted on behalf of such Existing Holder, up to and including the excess of the number of Outstanding Preferred Shares held by such Existing Holder over the number of Preferred Shares subject to any Hold Order referred to in Section 11.10(c)(iv)(A) above (and if more than one Bid submitted on behalf of such Existing Holder specifies the same rate per annum and together they cover more than the remaining number of shares that can be the subject of valid Bids after application of Section 11.10(c)(iv)(A) above and of the foregoing portion of this Section 11.10(c)(iv)(B) to any Bid or Bids specifying a lower rate or rates per annum, the number of shares subject to each of such Bids shall be reduced pro rata so that such Bids, in the aggregate, cover exactly such remaining number of shares); and the number of shares, if any, subject to Bids not valid under this Section 11.10(c)(iv)(B) shall be treated as the subject of a Bid by a Potential Holder; and

(C) any Sell Order shall be considered valid up to and including the excess of the number of Outstanding Preferred Shares held by such Existing Holder over the number of Preferred Shares subject to Hold Orders referred to in Section 11.10(c)(iv)(A) and Bids referred to in
Section 11.10(c)(iv)(B); provided that if more than one Sell Order is submitted on behalf of any Existing Holder and the number of Preferred Shares subject to such Sell Orders is greater than such excess, the number of Preferred Shares subject to each of such Sell Orders shall be reduced pro rata so that such Sell Orders, in the aggregate, cover exactly the number of Preferred Shares equal to such excess.

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

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

-72-

(vii) The Trust shall not be responsible for a Broker-Dealer's failure to act in accordance with the instructions of Beneficial Owners or Potential Beneficial Owners or failure to comply with the provisions of this Section 11.10.

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

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

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

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

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

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

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

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

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

-73-

(ii) Promptly after the Auction Agent has made the determinations pursuant to Section 11.10(d)(i), the Auction Agent shall advise the Trust of the Maximum Applicable Rate and, based on such determinations, the Applicable Rate for the next succeeding Dividend Period as follows:

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

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

(C) if all of the Outstanding Preferred Shares are the subject of Submitted Hold Orders, that the Dividend Period next succeeding the Auction shall automatically be the same length as the immediately preceding Dividend Period and the Applicable Rate for the next succeeding Dividend Period shall be equal to 80% of the Reference Rate on the date of the Auction.

(e) Acceptance and Rejection of Submitted Bids and Submitted Sell Orders and Allocation of Shares. Existing Holders shall continue to hold the Preferred Shares that are subject to Submitted Hold Orders, and, based on the determinations made pursuant to Section 11.10(d)(i), the Submitted Bids and Submitted Sell Orders shall be accepted or rejected and the Auction Agent shall take such other action as set forth below:

(i) If Sufficient Clearing Bids have been made, subject to the provisions of Section 11.10(e)(iii) and Section 11.10(e)(iv), Submitted Bids and Submitted Sell Orders shall be accepted or rejected in the following order of priority and all other Submitted Bids shall be rejected:

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

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

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

(D) the Submitted Bid of each of the Existing Holders specifying a rate per annum that is equal to the Winning Bid Rate shall be rejected, thus entitling each such Existing Holder to continue to hold the Outstanding Preferred Shares that are the

-74-

subject of such Submitted Bid, unless the number of Outstanding Preferred Shares subject to all such Submitted Bids shall be greater than the number of Outstanding Preferred Shares ("Remaining Shares") equal to the excess of the Available Preferred Shares over the number of Outstanding Preferred Shares subject to Submitted Bids described in
Section 11.10(e)(i)(B) and Section 11.10(e)(i)(C), in which event the Submitted Bids of each such Existing Holder shall be accepted, and each such Existing Holder shall be required to sell Outstanding Preferred Shares, but only in an amount equal to the difference between (1) the number of Outstanding Preferred Shares then held by such Existing Holder subject to such Submitted Bid and (2) the number of Preferred Shares obtained by multiplying (x) the number of Remaining Shares by
(y) 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 sum of the number of Outstanding Preferred Shares subject to such Submitted Bids made by all such Existing Holders that specified a rate per annum equal to the Winning Bid Rate; and

(E) the Submitted Bid of each of the Potential Holders specifying a rate per annum that is equal to the Winning Bid Rate shall be accepted but only in an amount equal to the number of Outstanding Preferred Shares obtained by multiplying (x) the difference between the Available Preferred Shares and the number of Outstanding Preferred Shares subject to Submitted Bids described in Section 11.10(e)(i)(B), Section 11.10(e)(i)(C) and Section 11.10(e)(i)(D) by (y) 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 number of Outstanding Preferred Shares subject to such Submitted Bids made by all such Potential Holders that specified rates per annum equal to the Winning Bid Rate.

(ii) If Sufficient Clearing Bids have not been made (other than because all of the Outstanding Preferred Shares are subject to Submitted Hold Orders), subject to the provisions of Section 11.10(e)(iii), Submitted Orders shall be accepted or rejected as follows in the following order of priority and all other Submitted Bids shall be rejected:

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

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

(C) the Submitted Bids of each Existing Holder specifying any rate per annum that is higher than the Maximum Applicable Rate shall be accepted and the Submitted Sell Orders of each Existing Holder shall be accepted, in both cases only in an amount equal to the difference between (1) the number of Outstanding Preferred

-75-

Shares then held by such Existing Holder subject to such Submitted Bid or Submitted Sell Order and (2) the number of Preferred Shares obtained by multiplying (x) the difference between the Available Preferred Shares and the aggregate number of Outstanding Preferred Shares subject to Submitted Bids described in Section 11.10(e)(ii)(A) and Section 11.10(e)(ii)(B) by (y) a fraction the numerator of which shall be the number of Outstanding Preferred Shares held by such Existing Holder subject to such Submitted Bid or Submitted Sell Order and the denominator of which shall be the number of Outstanding Preferred Shares subject to all such Submitted Bids and Submitted Sell Orders.

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.

(iii) If, as a result of the procedures described in Section 11.10(e), 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 Preferred Share on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, round up or down the number of Preferred Shares to be purchased or sold by any Existing Holder or Potential Holder on such Auction Date so that each Outstanding Preferred Share purchased or sold by each Existing Holder or Potential Holder on such Auction Date shall be a whole Preferred Share.

(iv) If, as a result of the procedures described in Section 11.10(e), any Potential Holder would be entitled or required to purchase less than a whole Preferred Share on any Auction Date, the Auction Agent shall, in such manner as in its sole discretion it shall determine, allocate Preferred Shares for purchase among Potential Holders so that only whole Preferred Shares are purchased on such Auction Date by any Potential Holder, even if such allocation results in one or more of such Potential Holders not purchasing any Preferred Shares on such Auction Date.

(v) Based on the results of each Auction, the Auction Agent shall determine, with respect to each Broker-Dealer that submitted Bids or Sell Orders on behalf of Existing Holders or Potential Holders, the aggregate number of Outstanding Preferred Shares to be purchased and the aggregate number of the Outstanding Preferred Shares to be sold by such Potential Holders and Existing Holders and, to the extent that such aggregate number of Outstanding shares to be purchased and such aggregate number of Outstanding shares to be sold differ, the Auction Agent shall determine to which other Broker-Dealer or Broker-Dealers acting for one or more purchasers such Broker-Dealer shall deliver, or from which other Broker-Dealer or Broker-Dealers acting for one or more sellers such Broker-Dealer shall receive, as the case may be, Outstanding Preferred Shares.

(f) Miscellaneous.

(i) To the extent permitted by applicable law, the Trust may in its sole discretion interpret the provisions of this Section 11.10 to resolve any inconsistency or ambiguity,

-76-

remedy any formal defect or make any other change or modification that does not substantially adversely affect the rights of Beneficial Owners of Preferred Shares.

(ii) Unless otherwise permitted by the Trust, a Beneficial Owner or an Existing Holder (A) may sell, transfer or otherwise dispose of Preferred Shares only pursuant to a Bid or Sell Order in accordance with the procedures described in this Section 11.10 or to or through a Broker-Dealer or to such other persons as may be permitted by the Trust, provided that in the case of all transfers other than pursuant to Auctions such Beneficial Owner or Existing Holder, its Broker-Dealer, if applicable, or its Agent Member advises the Auction Agent of such transfer and (B) except as otherwise required by law, shall have the ownership of the Preferred Shares held by it maintained in book entry form by the Securities Depository in the account of its Agent Member, which in turn will maintain records of such Beneficial Owner's beneficial ownership. The Trust may not submit an Order in any Auction.

(iii) All of the Outstanding Preferred Shares of a series shall be registered in the name of the nominee of the Securities Depository unless otherwise required by law or unless there is no Securities Depository. If there is no Securities Depository, at the Trust's option and upon its receipt of such documents as it deems appropriate, any Preferred Shares may be registered in the Stock Register in the name of the Beneficial Owner thereof and such Beneficial Owner thereupon will be entitled to receive certificates therefor and required to deliver certificates therefor upon transfer or exchange thereof.

11.11 Securities Depository; Stock Certificates. (a) If there is a Securities Depository, all of the Preferred Shares of each series shall be issued to the Securities Depository and registered in the name of the Securities Depository or its nominee. Certificates may be issued as necessary to represent Preferred Shares. All such certificates shall bear a legend to the effect that such certificates are issued subject to the provisions restricting the transfer of Preferred Shares contained in these Bylaws. Unless the Trust shall have elected, during a Non-Payment Period, to waive this requirement, the Trust will also issue stop-transfer instructions to the Auction Agent for the Preferred Shares. Except as provided in paragraph (b) below, the Securities Depository or its nominee will be the Holder, and no Beneficial Owner shall receive certificates representing its ownership interest in such shares.

(b) If the Applicable Rate applicable to all Preferred Shares of a series shall be the Non-Payment Period Rate or there is no Securities Depository, the Trust may at its option issue one or more new certificates with respect to such shares (without the legend referred to in Section 11.11(a)) registered in the names of the Beneficial Owners or their nominees and rescind the stop-transfer instructions referred to in Section 11.11(a) with respect to such shares.

ARTICLE 12
Amendment to the Bylaws

12.1 General. Except to the extent that the Declaration of Trust or applicable law requires a vote or consent of Shareholders, these Bylaws may be amended, changed, altered or

-77-

repealed, in whole or part, only by resolution of a majority of the Trustees then in office at any meeting of the Trustees, or by one or more writings signed by such Trustees.

12.2 Article 11. Without limiting the provisions of Section 12.1, the Board of Trustees of the Trust may, by resolution duly adopted, without shareholder approval (except as otherwise required by Article 11 or required by applicable law), amend Article 11 to (a) reflect any amendments thereto which the Board of Trustees of the Trust is entitled to adopt pursuant to the terms of Article 11 without shareholder approval or (b) add additional series of Preferred Shares or additional shares of a series of Preferred Shares (and terms relating thereto) to the series and Preferred Shares described herein. Each such additional series and all such additional Preferred Shares shall be governed by the terms of Article 11.

(a) If, at the time this Agreement is executed and delivered, it is necessary for the Registration Statement or a post-effective amendment thereto to be declared effective under the 1933 Act before the offering of the Preferred Shares may commence, the Fund will use its reasonable best efforts to cause the Registration Statement or such post-effective amendment to become effective under the 1933 Act as soon as possible. If the Registration Statement has become effective and the Prospectus contained therein omits certain information at the time of effectiveness pursuant to Rule 430A of the 1933 Act Rules and Regulations, the Fund will file a prospectus including such information pursuant to Rule 497(h) of the 1933 Act Rules and Regulations, as promptly as practicable, but no later than the second business day following the earlier of the date of the determination of the offering price of the Preferred Shares or the date the Prospectus is first used after the effective date of the Registration Statement. If the Registration Statement has become effective and the Prospectus contained therein does not so omit such information, the Fund will file a Prospectus pursuant to Rule 497(c) or a certification pursuant to Rule 497(j) of the 1933 Act Rules and Regulations as promptly as practicable, but no later than the fifth business day following the date of the later of the effective date of the Registration Statement or the commencement of the public offering of the Preferred Shares after the effective date of the Registration Statement. The Fund will advise you promptly and, if requested by you, will confirm such advice in writing (i) when the Registration Statement or such post-effective amendment has become effective and (ii) when the Prospectus has been timely filed pursuant to Rule 497(c) or Rule 497(h) of the 1933 Act Rules and Regulations or the certification permitted pursuant to Rule 497(j) of the 1933 Act Rules and Regulations has been timely filed, whichever is applicable.

(b) The Fund will advise you promptly and, if requested by you, will confirm such advice in writing: (i) of any request made by the Commission, within three years after the date of this Agreement, for amendment of or a supplement to the Registration Statement, any Prepricing Prospectus or the Prospectus (or any amendment or supplement to any of the foregoing) or for additional information, (ii) of the issuance by the Commission, the National Association of Securities Dealers, Inc. (the "NASD"), any state securities commission, any national securities exchange, any arbitrator, any court or any other governmental, regulatory, self-regulatory or administrative agency or any official, within three years after the date of this Agreement, of any order suspending the effectiveness of the Registration Statement, prohibiting or suspending the use of the Prospectus, any Prepricing Prospectus or any sales material (as hereinafter defined), of any notice pursuant to Section 8(e) of the 1940 Act, of the suspension of qualification of the Preferred Shares for offering or sale in any jurisdiction, or the initiation or contemplated initiation of any proceeding for any such purposes, (iii) of receipt by the Fund, the Investment Adviser or any representative or attorney of the Fund or the Investment Adviser, within three years after the date of this Agreement, of any other material communication from the Commission, the NASD, any state securities commission, any national securities exchange, any arbitrator, any court or any other governmental, regulatory, self-regulatory or administrative agency or any official relating to the Fund, the Registration Statement, the 1940 Act Notification, the Prospectus, any Prepricing Prospectus, any sales material (as hereinafter defined) (or any amendment or

4

Securities Exchange Act of 1934, as amended (the "1934 Act"), without delivering a copy of such information, documents or reports to you prior to or concurrently with such filing.

16

agreed in writing to the employment of such counsel and the payment of such fees and expenses in connection with the defense of such action, suit or proceeding, (ii) the Fund and the Investment Adviser have failed within a reasonable period of time in light of the circumstances known to the Fund or the Investment Adviser, as the case may be, to assume the defense and employ counsel or (iii) the named parties to any such action, suit or proceeding (including any impleaded parties) include both such Underwriter or such controlling person and the Fund or the Investment Adviser and such Underwriter or such controlling person shall have been advised by its counsel that representation of such indemnified party and the Fund or the Investment Adviser by the same counsel would be inappropriate under applicable standards of professional conduct (whether or not such representation by the same counsel has been proposed) due to actual or potential differing interests between them (in which case the Fund and the Investment Adviser shall not have the right to assume the defense of such action, suit or proceeding on behalf of such Underwriter or such controlling person). It is understood, however, that the Fund and the Investment Adviser shall, in connection with any one such action, suit or proceeding or separate but substantially similar or related actions, suits or proceedings in the same jurisdiction arising out of the same general allegations or circumstances be liable for the reasonable fees and expenses of only one separate firm of attorneys (in addition to any local counsel if there is any action, suit or proceeding in more than one jurisdiction) at any time for all such Underwriters and controlling persons, which firm shall be designated in writing by Citigroup Global Markets Inc. and that, subject to the requirements of 1940 Act Release No. 11330, all such fees and expenses shall be reimbursed promptly as they are incurred. The Fund and the Investment Adviser shall not be liable for any settlement of any such action, suit or proceeding effected without the written consent of the Fund or the Investment Adviser, but if settled with such written consent or if there be a final judgment for the plaintiff in any such action, suit or proceeding, the Fund and the Investment Adviser agree to indemnify and hold harmless any Underwriter, to the extent provided in the preceding paragraph, and any such controlling person from and against any loss, liability, damage or expense by reason by such settlement or judgment.

(c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Fund and the Investment Adviser, and any of their respective trustees, directors, shareholders, partners, managers, members and officers (including any officers of the Fund who sign the Registration Statement) and any person who controls the Fund or the Investment Adviser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and the successors and assigns of the foregoing, to the same extent as the foregoing indemnity from the Fund and the Investment Adviser to each Underwriter, but only with respect to information furnished in writing by or on behalf of such Underwriter through you expressly for use in the Registration Statement, the Prospectus, any Prepricing Prospectus or any sales material (or any amendment or supplement to any of the foregoing). If any action, suit or proceeding shall be brought against the Fund or the Investment Adviser, any of their trustees, directors, partners, managers, members, shareholders, officers or any such controlling person, based on the Registration Statement, the Prospectus, any Prepricing Prospectus or any sales material (or any amendment or supplement to any of the foregoing) and in respect of which indemnity

17

may be sought against any Underwriter pursuant to this paragraph (c), such Underwriter shall have the rights and duties given to the Fund and the Investment Adviser by paragraph (b) above (except that if the Fund or the Investment Adviser shall have assumed the defense thereof such Underwriter shall not be required to do so, but may employ separate counsel therein and participate in the defense thereof, but the fees and expenses of such counsel shall be at such Underwriter's expense) and the Fund and the Investment Adviser, their trustees, directors, partners, managers, members, shareholders, officers and any such controlling person shall have the rights and duties given to the Underwriters by paragraph (b) above. The foregoing indemnity agreement shall be in addition to any liability which the Underwriters may otherwise have.

(d) If the indemnification provided for in this section 8 is unavailable to an indemnified party under paragraphs (a) or (c) hereof in respect of any losses, claims, damages, liabilities or expenses referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Fund and the Investment Adviser on the one hand (treated jointly for this purpose as one person) and the Underwriters on the other hand (treated jointly for this purpose as one person) from the offering of the Preferred Shares or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Fund and the Investment Adviser on the one hand (treated jointly for this purpose as one person) and of the Underwriters on the other hand (treated jointly for this purpose as one person) in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Fund and the Investment Adviser on the one hand (treated jointly for this purpose as one person) and the Underwriters on the other hand (treated jointly for this purpose as one person) shall be deemed to be in the same respective proportions as the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Fund as set forth in the table on the cover page of the Prospectus and the total payments received by the Underwriters with respect to the Preferred Shares as set forth in the table on the cover page of the Prospectus, bear to the aggregate public offering price of the Preferred Shares. The relative fault of the Fund and the Investment Adviser on the one hand (treated jointly for this purpose as one person) and of the Underwriters on the other hand (treated jointly for this purpose as one person) shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Fund and the Investment Adviser on the one hand (treated jointly for this purpose as one person) or by the Underwriters on the other hand (treated jointly for this purpose as one person) and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

18

(e) The Fund, the Investment Adviser and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities and expenses referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with defending any such action, suit or proceeding. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price of the Preferred Shares underwritten by it and distributed to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters' obligations to contribute pursuant to this Section 8 are several in proportion to the respective number of Preferred Shares set forth opposite their names in Schedule I (or such numbers of Preferred Shares increased as set forth in Section 10 hereof) and not joint.

(f) No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action, suit or proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability from claimants on claims that are the subject matter of such action, suit or proceeding.

(g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 8 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 8 and the representations and warranties of the Fund and the Investment Adviser set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter, the Fund, the Investment Adviser or their shareholders, trustees, directors, managers, members or officers or any person controlling the Fund or the Investment Adviser (control to be determined within the meaning of
Section 15 of the 1933 Act or Section 20 of the 1934 Act), (ii) acceptance of any Preferred Shares and payment therefor hereunder and
(iii) any termination of this Agreement. A successor to any Underwriter or to the Fund, the Investment Adviser or their shareholders, trustees, directors, managers, members or officers or any person controlling any Underwriter, the Fund or the Investment Adviser shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 8. The Fund and the Investment Adviser and each Underwriter agree promptly to notify each other of the commencement of any action, suit or proceeding against it and, in the case of the Fund or the Investment Adviser, against any of the Fund's or the Investment Adviser's

19

shareholders, partners, trustees, managers, members or officers in connection with the issuance and sale of the Preferred Shares, or in connection with the Registration Statement or Prospectus.

Notwithstanding any other provision in this Section 8, no person shall be entitled to indemnification or contribution under this Agreement against any loss, claim, damage, liability or expense arising by reason of such person's willful misfeasance, bad faith, gross negligence or reckless disregard in the performance of its duties and obligations hereunder.

9. Conditions of Underwriters' Obligations. The several obligations of the Underwriters to purchase any Preferred Shares hereunder are subject to the accuracy of and compliance with the representations, warranties and agreements of and by the Fund and the Investment Adviser contained herein on and as of the date hereof, the date on which the Registration Statement becomes or became effective, the date of the Prospectus (and of any amendment or supplement thereto), and the Closing Date; to the accuracy and completeness of all statements (subject to any applicable qualifications contained therein) made by the Fund, the Investment Adviser or any of their officers in any certificate delivered to the Underwriters or their counsel pursuant to this Agreement and to the following conditions:

(b) You shall have received on the Closing Date two opinions of Ropes & Gray, counsel for the Fund, dated the Closing Date and addressed to you, substantially in the form of Exhibits A1 and A2 to this Agreement.

(f) You shall have received letters addressed to you and dated the date hereof and the Closing Date from PricewaterhouseCoopers LLP, independent certified public accountants, substantially in the forms heretofore approved by you.

(g) (i) No order suspending the effectiveness of the registration statement or the Registration Statement or prohibiting or suspending the use of the Prospectus (or any amendment or supplement thereto) or any Prepricing Prospectus or any sales material shall have been issued and no proceedings for such purpose or for the purpose of commencing an enforcement action against the Fund, the Advisers or, with respect to the transactions contemplated by the Prospectus (or any amendment or supplement thereto) and this Agreement, any Underwriter, may be pending before or, to the knowledge of the Fund, the Advisers or any Underwriter, shall be threatened or contemplated by the Commission at or prior to the Closing Date and that any request for additional information on the part of the Commission (to be included in the Registration Statement, the Prospectus or otherwise) be complied with to the satisfaction of the Underwriters; (ii) since the date as of which information is given in the Registration Statement and the Prospectus, there shall not have been any change in the shares of beneficial interest of the Fund, other than through the issuance or purchase of common shares pursuant to any dividend reinvestment plan of the Fund relating thereto, nor any material increase in debt of the Fund from that set forth in the Prospectus and the Fund shall not have sustained any material liabilities or obligations, direct or contingent, other than those reflected in the Prospectus (and any amendment or supplement thereto); (iii) since the date of the Prospectus there shall not have been any material, adverse change in the condition (financial or other), business, properties, net assets or results of operations of the Fund or the Advisers; (iv) the Fund and the Advisers must not have sustained any material loss or interference with their business from any court or from legislative or other governmental action, order or decree or from any other occurrence not described in the Registration Statement and the Prospectus (and any amendment or supplement to either of them); and

(h) Subsequent to the effective date of this Agreement and prior to the Closing Date, there shall not have occurred (i) any change or any development involving a prospective change in or affecting the condition (financial or other), business, properties, net assets or results of operations of the Fund or the Advisers not contemplated by the Prospectus (and any amendment or supplement thereto), which would materially, adversely affect the market for the Preferred Shares or
(ii) any event or development

21

relating to or involving the Fund, the Advisers or any officer or trustee or director of the Fund or the Advisers which makes any statement of a material fact made in the Prospectus (or any amendment or supplement thereto) untrue or which requires the making of any addition to or change in the Prospectus (or any amendment or supplement thereto) in order to state a material fact required by the 1933 Act, the 1940 Act, the Rules and Regulations or any other law to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, if amending or supplementing the Prospectus (or any amendment or supplement thereto) to reflect such event or development would materially, adversely affect the market for the Preferred Shares.

(i) Neither the Fund nor the Investment Adviser shall have failed at or prior to the Closing Date to have performed or complied in all material respects with any of the agreements herein contained and required to be performed or complied with by them at or prior to the Closing Date.

22

from such officers of the Fund, there has not been any change in the shares of beneficial interest of the Fund, other than through the issuance or purchase of common shares pursuant to any dividend reinvestment plan of the Fund relating thereto, nor any material increase in the debt of the Fund from that set forth in the Prospectus and the Fund has not sustained any material liabilities or obligations, direct or contingent, other than those reflected in the Prospectus (and any amendment or supplement thereto).

(k) The Fund shall have furnished to you a report showing compliance with the asset coverage requirements of the 1940 Act and a Preferred Shares Basic Maintenance Report (as defined in the By-Laws), each dated the Closing Date and in form and substance satisfactory to you. Each such report shall assume the receipt of the net proceeds from the sale of the Preferred Shares and may use portfolio holdings and valuations as of the close of business of any day not more than six business days preceding the Closing Date, provided, however, that the Fund represents in such report that its total net assets as of the Closing Date have not declined by 5% or more from such valuation date.

(l) The Fund shall have delivered and the Underwriters shall have received evidence satisfactory to the Underwriters that each series of Preferred Shares is rated `Aaa' by Moody's and `AAA' by Fitch as of the Closing Date, and there shall not have been given any notice of any intended or potential downgrading, or of any review for a potential downgrading, in the rating accorded to the shares of each series of the Preferred Shares by either Rating Agency.

(m) The Fund, the Investment Adviser and the Subadviser shall have furnished to you such further certificates, documents and opinions of counsel as are listed in Schedule II hereto.

All such opinions, certificates, letters and other documents will be in compliance with the provisions hereof only if they are satisfactory in form and substance to you and your counsel acting in good faith.

Any certificate or document signed by any officer of the Fund or the Advisers and delivered to the Underwriters or to Underwriters' counsel shall be deemed a representation and warranty by the Fund or the Advisers, as applicable, to each Underwriter as to the statements made therein.

10. Effective Date of Agreement. This Agreement shall become effective:
(i) upon the execution and delivery hereof by the parties hereto; or (ii) if, at the time this Agreement is executed and delivered, it is necessary for the Registration Statement or a post-effective amendment thereto to be declared effective before the offering of the Preferred Shares may commence, when notification of the effectiveness of the Registration Statement or such post-effective amendment has been released by the Commission. Until such time as this Agreement shall have become effective, it may be terminated by the Fund by notifying you or by you by notifying the Fund.

23

If any one or more of the Underwriters shall fail or refuse to purchase Preferred Shares which it or they have agreed to purchase hereunder and the aggregate number of Preferred Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Preferred Shares, each non-defaulting Underwriter shall be obligated, severally, in the proportion which the aggregate number of Preferred Shares set forth opposite its name in Schedule I hereto bears to the aggregate number of Preferred Shares set forth opposite the names of all non-defaulting Underwriters or in such other proportion as you may specify in accordance with the Citigroup Global Markets Inc. Master Agreement Among Underwriters, to purchase Preferred Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase. If any Underwriter or Underwriters shall fail or refuse to purchase Preferred Shares and the aggregate number of Preferred Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Preferred Shares and arrangements satisfactory to you and the Fund for the purchase of such Preferred Shares by one or more non-defaulting Underwriters or other party or parties reasonably satisfactory to the Underwriters and the Fund are not made within 72 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Fund. In any such case which does not result in termination of this Agreement, either you or the Fund shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability to the Fund, the Investment Adviser or any non-defaulting Underwriter in respect to any such default of any such Underwriter under this Agreement. The term "Underwriter" as used in this Agreement includes, for all purposes of this Agreement, any party not listed in Schedule I hereto who, with your approval and the approval of the Fund, purchases Preferred Shares which a defaulting Underwriter agreed, but failed or refused, to purchase.

Any notice under this Section 10 may be made by telegram, telecopy or telephone but shall be subsequently confirmed by letter.

11. Termination of Agreement. This Agreement shall be subject to termination in your absolute discretion, without liability on the part of the Underwriters to the Fund or the Investment Adviser, by notice given to the Fund or the Investment Adviser prior to delivery of and payment for the Preferred Shares, if at any time prior to such time (i) trading in the Fund's common shares shall have been suspended by the Commission or the New York Stock Exchange (the "NYSE") or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices for trading in securities generally shall have been established on such Exchange, (ii) a commercial 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 your sole judgment, impracticable or inadvisable to proceed with the offering or delivery of the Preferred Shares as contemplated by the Prospectus (exclusive of any supplement thereto). Notice of such termination may be given to the Fund or the Investment Adviser by telegram, telecopy or telephone and shall be subsequently confirmed by letter.

24

12. Expenses. If the transactions contemplated by this Agreement are consummated, the Fund agrees to pay the following costs and expenses and all other costs and expenses incident to the performance by the Fund of its obligations hereunder: (a) the preparation, printing or reproduction, filing (including, without limitation, the filing fees prescribed by the 1933 Act, the 1940 Act and the Rules and Regulations) and distribution of the Registration Statement (including exhibits thereto), the Prospectus and each Prepricing Prospectus and all amendments or supplements to any of them, (b) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, the Prospectus, each Prepricing Prospectus, any sales material and all amendments or supplements to any of them as may be reasonably requested by the Underwriters for use in connection with the offering and sale of the Preferred Shares, (c) the preparation, printing, authentication, issuance and delivery of certificates for the Preferred Shares, including any stamp taxes and transfer agent and registrar fees payable in connection with the original issuance and sale of such Preferred Shares, (d) the registrations or qualifications, if necessary, of the Preferred Shares for offer and sale under the securities or Blue Sky laws of the several states as provided in Section 5(g) hereof (including the reasonable fees, expenses and disbursements of counsel for the Underwriters relating to the preparation, printing or reproduction and delivery of the preliminary and supplemental Blue Sky Memoranda and such registration and qualification), (e) the fees and expenses of the Fund's independent accountants, counsel for the Fund and of the transfer agent and the auction agent, (f) the printing (or reproduction) and delivery of this Agreement, any dealer agreements, the preliminary and supplemental Blue Sky Memoranda and all other company-authorized agreements or other documents printed (or reproduced) and delivered in connection with the offering of the Preferred Shares, (g) the filing fees and the fees and expenses of counsel for the Underwriters, if any, in connection with any filings required to be made with the NASD and incurred with respect to the review of the offering of the Preferred Shares by the NASD, and (h) the fees paid to the Rating Agencies.

Notwithstanding the foregoing, in the event that the sale of the Preferred Shares is not consummated pursuant to Section 2 hereof, (i) the Investment Adviser will pay the costs and expenses of the Fund set forth above in this
Section 12 (a) through (h), (ii) reimbursements of Underwriter expenses in connection with the offering shall be made in accordance with Section 5(k) hereof and (iii) no party will be under any liability to any other person with respect to the costs and expenses described in Section 5(k) hereof and this
Section 12 except as is described in (i) and (ii) above. (For the sake of clarity, the foregoing sentence does not relieve any defaulting Underwriter from liability to the Fund, the Investment Manager or any non-defaulting Underwriter in respect of any such default to any Underwriter under this Agreement.)

13. Information Furnished by the Underwriters. The statements set forth in the [last sentence of the front cover page in the Prospectus, as well as, under the caption "Underwriting" in the Prospectus, the names of the underwriters and numbers of Preferred Shares listed opposite such names in the first paragraph, each sentence of the third paragraph (other than the second sentence) and the seventh paragraph] constitute the only information relating to any Underwriter furnished to the Fund in writing by or on behalf of the Underwriters through you as such information is referred to herein, expressly for use in the Prospectus. The Underwriters severally confirm that these statements are correct in all material respects.

25

14. Miscellaneous. Except as otherwise provided in Sections 5, 10 and 11 hereof, notice given pursuant to any provision of this Agreement shall be in writing and shall be delivered (a) if to the Fund or the Investment Adviser, c/o PIMCO Advisors Fund Management LLC, 1345 Avenue of the Americas, New York, New York, 10105, Attention: Brian Shlissel, Treasurer or (b) if to you, at the office of Citigroup Global Markets Inc. at 388 Greenwich Street, New York, New York 10013, Attention: Manager, Investment Banking Division.

This Agreement has been and is made solely for the benefit of the several Underwriters, the Fund and the Investment Adviser, and to the extent provided in
Section 8 hereof their trustees, directors, partners, members, managers, shareholders and officers and the other controlling persons referred to in
Section 8 hereof and their respective successors and assigns to the extent provided herein and no other person shall acquire or have any right under or by virtue of this Agreement. Neither the term "successor" nor the term "successors and assigns" as used in this Agreement shall include a purchaser from any Underwriter of any of the Preferred Shares in his status as such purchaser.

A copy of the Declaration of Trust of the Fund is on file with the Secretary of State of The Commonwealth of Massachusetts. This Agreement has been executed on behalf of the Fund by the trustees of the Fund in such capacity and not individually and the obligations of this Agreement are not binding upon any officer, any of the trustees or the shareholders individually but are binding only upon the assets and property of the Fund.

15. Applicable Law; Counterparts. This Agreement shall be governed by and construed in accordance with the laws of the State of New York.

This Agreement may be signed in various counterparts which together constitute one and the same instrument. If signed in counterparts, this Agreement shall not become effective unless at least one counterpart hereof shall have been executed and delivered on behalf of each party hereto.

26

Please confirm that the foregoing correctly sets forth the agreement among the Fund and the Investment Adviser and the several Underwriters.

Very truly yours,

We have acted as counsel to PIMCO High Income Fund (the "Fund") in connection with the proposed issuance of 7,200 Auction Rate Cumulative Preferred Shares, Series M, 7,200 Auction Rate Cumulative Preferred Shares, Series T, 7,200 Auction Rate Cumulative Preferred Shares, Series W, 7,200 Auction Rate Cumulative Preferred Shares, Series TH, and 7,200 Auction Rate Cumulative Preferred Shares, Series F (together, the "Preferred Shares"). This opinion is furnished to you pursuant to Section 9(b) of the Underwriting Agreement dated as of June __, 2003 (the "Underwriting Agreement"), among the Fund, PIMCO Advisors Fund Management LLC (the "Investment Manager") and Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and UBS Securities LLC (the "Underwriters"). Capitalized terms used in this opinion, unless otherwise defined, have the meanings specified in the Underwriting Agreement.

We have examined signed copies of the registration statement of the Fund on Form N-2 (File No. 333-104915) under the Securities Act of 1933, as amended (the "Securities Act") (which also constitutes Amendment No. 5 to the Fund's Registration Statement on Form N-2 (File No. 811-21311) under the Investment Company Act of 1940, as amended (the "Investment Company Act")), including all exhibits thereto, as filed with the Securities and Exchange Commission (the "Commission") on May 1, 2003 (the "Original Registration Statement"), Pre-Effective Amendment No. 1 to the Original Registration Statement, including all exhibits thereto, as filed with the Commission on June 16, 2003 ("Pre-Effective Amendment No. 1") and Pre-Effective


Amendment No. 2 to the Original Registration Statement, including all exhibits thereto, as filed with the Commission on June __, 2003 ("Pre-Effective Amendment No. 2," and together with Pre-Effective Amendment No. 1 and the Original Registration Statement, the "Registration Statement"); the Fund's Notification of Registration on Form N-8A (File No. 811-21311) under the Investment Company Act, as filed with the Commission on February 21, 2003 (the "Notification of Registration"); the Fund's Agreement and Declaration of Trust, as amended to the date hereof (the "Declaration of Trust"), on file in the offices of the Secretary of State of The Commonwealth of Massachusetts and the Clerk of the City of Boston; the Second Amended and Restated Bylaws of the Fund, as amended to the date hereof (the "Amended Bylaws"); a copy of the Prospectus dated June __, 2003, relating to the Preferred Shares and the Statement of Additional Information of the Fund dated June __, 2003, each as filed with the Commission pursuant to Rule 497 under the Securities Act on June __, 2003 (together, the "Prospectus"); the Investment Management Agreement dated as of April 8, 2003, between the Fund and the Investment Manager (the "Investment Management Agreement"); the Portfolio Management Agreement dated as of April 8, 2003, between Pacific Investment Management Company LLC (the "Portfolio Manager") and the Investment Manager (the "Portfolio Management Agreement"), as agreed to and accepted by the Fund; the Custodian and Investment Accounting Agreement dated as of April 8, 2003, between the Fund and State Street Bank and Trust Company (the "Custodian Agreement"); the Auction Agency Agreement dated as of June __, 2003, between the Fund and Deutsche Bank Trust Company Americas (the "Auction Agency Agreement"); the Transfer Agency Services Agreement dated as of April 14, 2003, between the Fund and PFPC Inc. (the "Transfer Agency Agreement" and together with the Custodian Agreement and the Auction Agency Agreement, the "Fund Agreements"); and the Underwriting Agreement. Additionally, we have relied solely upon the oral representation of Keith O'Connell of the Commission staff to the effect that the Registration Statement became effective as of ___ p.m. on June __, 2003, and the oral representation by a member of the Commission staff on the date hereof that as of ___ a.m., no stop order suspending the effectiveness of the Registration Statement had been issued and no proceeding for any such purpose was pending or threatened.

We have also examined and relied upon the original or copies of minutes of the meetings or written consents of the shareholders and the Board of Trustees of the Fund, the documents delivered to the Underwriters by the Fund and the Investment Manager dated as of the date hereof pursuant to the Underwriting Agreement and such other documents, including certificates of officers of the Fund, as we have deemed necessary for purposes of rendering our opinions below. For purposes of paragraph 2 below, we have relied solely on (1) the certificate dated as of June __, 2003, of the Secretary of State of the State of California as to the entitlement of the Fund to transact intrastate business in the State of California, (2) a Certificate of the Secretary of State of the State of New York dated June __, 2003, certifying copies of (a) a Certificate of Designation by the Fund dated April 8, 2003, and (b) a Statement under Section 18 of the New York General Associations Law, (3) a Filing Receipt of the Department of State of the State of New York dated April 10, 2003 relating to the Fund and (4) a LEXIS search on June __, 2003 of the New York Department of State, Corporate Record, showing the "status" of the Fund as


"active" and noting that "good standing status can only be determined by performing a search in the records of both the Department of State Corporation Records and the Department of Tax and Franchise." We have assumed the genuineness of the signatures on all documents examined by us, the authenticity of all documents submitted to us as originals and the conformity to the corresponding originals of all documents submitted to us as copies. For purposes of our opinion regarding the effectiveness of the Registration Statement, we are relying solely on the oral representations of the Commission staff.

We express no opinion as to the laws of any jurisdiction other than The Commonwealth of Massachusetts and the United States of America. We call your attention to the fact that each of the Underwriting Agreement and the Auction Agency Agreement provides that it is to be governed by and construed in accordance with the laws of the State of New York, to the fact that the Transfer Agency Agreement provides that it is to be governed by and construed in accordance with the laws of the State of Delaware and to the fact that the Investment Management Agreement does not provide that it is to be governed by the laws of any particular jurisdiction. In rendering the opinion as to enforceability expressed in paragraph 6 below, we have limited the scope of our opinion to the conclusions that would be reached by a Massachusetts court that had determined that each of the Fund Agreements would be governed by, and construed in accordance with, the internal laws of The Commonwealth of Massachusetts. Further, we express no opinion as to the state securities or Blue Sky laws of any jurisdiction, including The Commonwealth of Massachusetts.

For purposes of our opinion set forth in paragraph 2 below with respect to the power and authority of the Fund to own, lease and operate its properties and conduct its business, we have relied upon certificates of officers of the Fund as to the states in which the Fund leases or owns real property or in which it conducts material operations.

Insofar as this opinion relates to factual matters, we have made inquiries to officers of the Fund, the Investment Manager and the Portfolio Manager to the extent we believe reasonable with respect to such matters and have relied inter alia upon representations made by the Fund and the Investment Manager in the Underwriting Agreement, representations made by the Portfolio Manager to the Investment Manager and representations made to us by one or more officers of the Fund, the Investment Manager or the Portfolio Manager. We have not independently verified the accuracy of such representations. Where our opinion relates to our "knowledge," that term means the conscious awareness of facts or other information by any lawyer in our firm giving substantive attention to the representation of the Fund with respect to the transactions contemplated by the Underwriting Agreement, and does not require or imply (i) any examination of this firm's, any such lawyer's or any other person's or entity's files, or (ii) that any inquiry was made of any lawyer (other than the lawyers described above). In respect of our opinions set forth in paragraphs 8, 10 and 11 below, we have not searched the dockets of any court, administrative body or other filing office in any jurisdiction.

Based upon and subject to the foregoing, we are of the opinion that:


1. The Registration Statement and all post-effective amendments filed with the Commission on or before the Closing Date, if any, are effective under the Securities Act; the filing of the Prospectus pursuant to Rule 497 under the Securities Act has been made in the manner and within the time period required by Rule 497; and based upon oral inquiries to the Commission staff on the date hereof, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceeding for any such purpose is pending or threatened by the Commission.

2. The Fund has been duly organized and is validly existing and in good standing as an unincorporated voluntary association under and by virtue of the laws of The Commonwealth of Massachusetts and has full power and authority to own or lease its properties and to conduct its business as described in the Registration Statement and the Prospectus. The Certificate of Designation relating to the Fund's conduct of business in the State of New York is on file with the Department of State of the State of New York, and the Fund is entitled to transact intrastate business in the State of California.

3. The Fund's authorized capitalization is as set forth in the Registration Statement and the Prospectus. The Preferred Shares conform in all material respects as to legal matters to the description of them under the sections entitled "Description of Preferred Shares" and "Description of Capital Structure" in the Prospectus. The Preferred Shares have been duly authorized and, when issued and delivered to the Underwriters against payment therefor in accordance with the terms of the Underwriting Agreement, will be validly issued, fully paid and, subject to the penultimate paragraph of this opinion letter, non-assessable. No person is entitled to any preemptive or other similar rights with respect to the Preferred Shares.

4. The outstanding common shares of beneficial interest of the Fund, par value $0.00001 per share, have been duly authorized and are validly issued, fully paid and, subject to the penultimate paragraph of this opinion letter, non-assessable.

5. The Fund was deemed to be registered under Section 8(a) of the Investment Company Act upon receipt by the Commission of the Notification of Registration. To our knowledge, the Commission has not issued to the Fund notice of any hearing or other proceeding to consider suspension or revocation of any such registration statement. All required action has been taken by the Fund under the Securities Act, the Investment Company Act and the rules and regulations thereunder in connection with the issuance and sale of the Preferred Shares to make the public offering and consummate the sale of the Preferred Shares pursuant to the Underwriting Agreement.

6. The Fund has, or at the relevant time had, full power and authority to enter into each of the Fund Agreements and to perform all of the terms and provisions thereof to be carried out by it. Each Fund Agreement has been duly and validly authorized, executed and delivered by the Fund. Each Fund Agreement complies in all material respects with all applicable provisions of the Investment Company Act and the Investment Advisers Act of 1940,


as amended, as the case may be, and the rules and regulations thereunder. Assuming due authorization, execution and delivery by the other parties thereto, each Fund Agreement constitutes the legal, valid and binding obligation of the Fund enforceable in accordance with its terms, subject as to enforcement to bankruptcy, insolvency, moratorium, reorganization and other laws of general applicability relating to or affecting creditors' rights and to general equity principles (regardless of whether enforceability is considered in a proceeding in equity or at law).

7. The Fund has, or at the relevant time had, full power and authority to enter into each of the Investment Management Agreement and the Underwriting Agreement and to perform all of the terms and provisions thereof to be carried out by it. The Investment Management Agreement and the Underwriting Agreement have been duly and validly authorized, executed and delivered by the Fund.

8. None of (a) the execution and delivery by the Fund of the Investment Management Agreement, the Underwriting Agreement or any of the Fund Agreements, (b) the issue and sale by the Fund of the Preferred Shares as contemplated by the Underwriting Agreement and (c) the performance by the Fund of its obligations under the Investment Management Agreement, the Underwriting Agreement or any of the Fund Agreements or the consummation by the Fund of the other transactions contemplated by the Investment Management Agreement, the Underwriting Agreement or any of the Fund Agreements conflicts or will conflict with, or results or will result in a breach of, the Declaration of Trust or the Amended Bylaws or, to our knowledge, any agreement or instrument to which the Fund is a party or by which the Fund is bound, or violates or will violate any federal or Massachusetts statute, law or regulation or any judgment, injunction, order or decree of any federal or Massachusetts governmental agency or body that is applicable to the Fund and that is known to us, which violation would have a material adverse effect on the condition or business of the Fund.

9. To our knowledge, the Fund is not currently in breach of, or in default under, any material written agreement or instrument to which it is a party or by which it or its property is bound or affected.

10. No consent, approval, authorization or order of or registration with any court or governmental agency or body or securities exchange or securities association is required by the Fund for the consummation by the Fund of the transactions contemplated in the Investment Management Agreement, the Underwriting Agreement and the Fund Agreements, except such as (a) have been obtained under the Securities Act, the Investment Company Act or the Securities Exchange Act of 1934, as amended, and (b) may be required by the National Association of Securities Dealers, Inc. or under state securities or Blue Sky laws in connection with the purchase and distribution of the Preferred Shares by the Underwriters pursuant to the Underwriting Agreement.

11. To our knowledge, there are no legal or governmental proceedings pending or threatened against the Fund, or to which the Fund or any of its properties is subject,


that are required to be described in the Registration Statement or the Prospectus but are not described therein as required.

12. To our knowledge, there are no agreements, contracts, indentures, leases or other instruments that are required to be described in the Registration Statement or the Prospectus or to be filed as an exhibit to the Registration Statement which have not been so described or filed as an exhibit or incorporated therein by reference.

13. Each of the sections in the Prospectus entitled "Tax Matters," to the extent that it states matters of United States law or legal conclusions with respect thereto, presents a fair summary of the principal federal income tax rules currently in effect applicable to the Fund and to the purchase, ownership and disposition of the Preferred Shares.

14. The Registration Statement (except for the financial statements and schedules, the notes thereto and any schedules and other financial data contained or incorporated by reference therein or omitted therefrom, as to which we express no opinion), at the effective time set forth above, and the Prospectus (except as aforesaid), as of the date thereof, complied as to form in all material respects with the applicable requirements of the Securities Act and the Investment Company Act and the rules and regulations thereunder.

We have not independently verified the accuracy, completeness or fairness of the statements made or the information contained in the Registration Statement or the Prospectus and, except in the respects and to the extent set forth in paragraphs 3, 13 and 14 above, we are not passing upon and do not assume any responsibility therefor. In the course of the preparation by the Fund of the Registration Statement and the Prospectus, we have participated in discussions with your representatives and employees and officers of the Fund, the Investment Manager and the Portfolio Manager and in discussions with the Fund's independent accountants, in which the business and the affairs of the Fund, the Investment Manager and the Portfolio Manager and the contents of the Registration Statement and the Prospectus were discussed. There is no assurance that all material facts as to the Fund, the Investment Manager, the Portfolio Manager and their affairs were disclosed to us or that our familiarity with the Fund and the Investment Manager or any familiarity with the Portfolio Manager is such that we would have necessarily recognized the materiality of such facts as were disclosed to us, and we have to a large extent relied upon statements of representatives of the Fund, the Investment Manager and the Portfolio Manager as to the materiality of the facts disclosed to us. On the basis of information that we have gained in the course of our representation of the Fund in connection with its preparation of the Registration Statement and the Prospectus and our participation in the discussions referred to above, no facts have come to our attention that would lead us to believe that, as of the effective date of the Registration Statement, the Registration Statement contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading, or that as of the date of the Prospectus and the date hereof the Prospectus contained an untrue statement of material fact or omitted to state a material fact necessary in order to make the statements therein, in light, in each case, of the circumstances


under which they were made, not misleading (in each case, other than the financial statements and schedules, the notes thereto and any schedules and other financial data contained or incorporated by reference therein or omitted therefrom, as to which we express no opinion).

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

This letter and the opinions expressed herein are furnished by us to you and are solely for benefit of the Underwriters, except that Simpson Thacher & Bartlett LLP may rely on this letter as to all matters governed by the laws of The Commonwealth of Massachusetts in delivering its opinion to you on the date hereof.

Very truly yours,

Re: PIMCO Advisors Fund Management LLC

Ladies and Gentlemen:

I am the Chief Legal Officer of PIMCO Advisors Fund Management LLC, a Delaware limited liability company ("PIMCO Advisors"), and have counseled PIMCO Advisors in such capacity in connection with the issuance and sale to you today by PIMCO High Income Fund, a voluntary association with transferable shares organized and existing under and by virtue of the laws of The Commonwealth of Massachusetts (commonly referred to as a Massachusetts business trust) (the "Fund"), of 7,200 Auction Rate Cumulative Preferred Shares, Series M, 7,200 Auction Rate Cumulative Preferred Shares, Series T, 7,200 Auction Rate Cumulative Preferred Shares, Series W, 7,200 Auction Rate Cumulative Preferred Shares, Series TH, and 7,200 Auction Rate Cumulative Preferred Shares, Series F, of the Fund (the "Preferred Shares"), pursuant to a registration statement on Form N-2 under the Securities Act of 1933, as amended (the "Act"), and the Investment Company Act of 1940, as amended (the "Investment Company Act"), filed with the Securities and Exchange Commission (the "Commission") on May 1, 2003 (Act File No. 333-104915, and Investment Company Act File No. 811-21311), as amended by Pre-Effective Amendment No. 1 filed with the Commission on June 16, 2003, and Pre-Effective Amendment No. 2 filed with the Commission on June __, 2003 (such registration statement, as amended, referred to herein as the "Registration Statement"), and an underwriting agreement


dated June __, 2003, by and among you, the Fund and PIMCO Advisors (the "Underwriting Agreement") relating to the issuance and sale by the Fund of the Preferred Shares.

This opinion is rendered to you pursuant to Section 9(c) of the Underwriting Agreement. Capitalized terms used herein without definition have the meanings assigned to them in the Underwriting Agreement.

As such legal officer, I have examined such matters of fact and questions of law as I have considered appropriate for purposes of rendering the opinions expressed below, except where a statement is qualified as to knowledge or awareness, in which case I have made no or limited inquiry as specified below. I have examined, among other things, the following:

(a) the Underwriting Agreement;

(b) that certain Investment Management Agreement by and between the Fund and PIMCO Advisors, dated as of April 8, 2003; and

(c) that certain Portfolio Management Agreement by and between Pacific Investment Management Company LLC and PIMCO Advisors, as accepted and agreed to by the Fund, dated as of April 8, 2003.

The documents described in subsections (a)-(c) above are referred to herein collectively as the "Transaction Documents."

In my examination, I have assumed the genuineness of all signatures (other than those of officers of PIMCO Advisors on the Transaction Documents), the authenticity of all documents submitted to me as originals, and the conformity to authentic original documents of all documents submitted to me as copies.

I have been furnished with, and with your consent have relied upon, certificates of officers of PIMCO Advisors with respect to certain factual matters. In addition, I have obtained and relied upon such certificates and assurances from public officials as I have deemed necessary.

I am opining herein as to the effect of the federal laws of the United States, the internal laws of the State of New York and the internal laws of the State of Delaware, and I express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or country or as to any matters of municipal law or the laws of any other local agencies within any state or country. My opinions set forth in paragraph 4 below are based upon my consideration of only those statutes, rules and regulations which, in my experience, are normally applicable to transactions similar to those contemplated by the Transaction Documents, generally.


Whenever a statement herein is qualified by "to my knowledge" or a similar phrase, it is intended to indicate that I do not have current actual knowledge of the inaccuracy of such statement. However, except as otherwise expressly indicated, I have not undertaken any independent investigation to determine the accuracy of any such statement, and no inference that I have any knowledge of any matters pertaining to such statement should be drawn from my position as Chief Legal Officer of PIMCO Advisors.

Subject to the foregoing and the other matters set forth herein, it is my opinion that, as of the date hereof:

1. PIMCO Advisors is a limited liability company and is validly existing and in good standing under the Delaware Limited Liability Company Act (6 Del. C ss.. 18-101, et seq.) with all necessary limited liability company power and authority to enter into and deliver the Transaction Documents and perform its obligations thereunder and to carry on its business as it is now being conducted and as described in the Registration Statement. Based solely on certificates from public officials dated _______, 2003, ________, 2003, and __________, 2003, respectively, I confirm that PIMCO Advisors is qualified to do business in the following States: California, New York and Connecticut, such States being those in which its ownership or leasing of property or its conducting of business may require such qualification and where failure to so qualify would have a material adverse effect on the ability of PIMCO Advisors to perform its obligations under the Investment Management Agreement and the Portfolio Management Agreement.

2. The execution, delivery and performance of the Transaction Documents by PIMCO Advisors have been duly authorized by all necessary limited liability company action of PIMCO Advisors and no other actions on the part of PIMCO Advisors or its unitholders or any subsidiary of PIMCO Advisors or its unitholders is necessary to authorize and consummate the transactions contemplated thereby, and the Transaction Documents have been duly executed and delivered by PIMCO Advisors.

3. Each of the Investment Management Agreement and the Portfolio Management Agreement constitutes a legally valid and binding agreement of PIMCO Advisors, enforceable against PIMCO Advisors in accordance with its terms.

4. Neither the execution and delivery of the Transaction Documents by PIMCO Advisors, nor the consummation by PIMCO Advisors of transactions contemplated thereby, nor compliance by PIMCO Advisors with any of the terms and provisions thereof will:

(i) violate any provision of the Limited Liability Company Agreement of PIMCO Advisors, effective October 23, 2002, which is still in full force and effect and which has not been amended or supplemented through the date hereof,


(ii) violate any federal, Delaware or New York statute, rule or regulation applicable to PIMCO Advisors (other than federal and state securities or blue sky laws, the Investment Company Act and the Investment Advisers Act of 1940, as amended (the "Advisers Act"), as to which I express no opinion),

(iii) violate any agreement to which PIMCO Advisors is a party or by which it is bound and which is material to PIMCO Advisors' businesses taken as a whole (the "Material Agreements"),

(iv) violate any order, writ, injunction or decree, known to me and applicable to PIMCO Advisors, or

(v) to the best of my knowledge, require any consents, approvals, authorizations, registrations, declarations or filings by PIMCO Advisors under any federal or Delaware statute, rule or regulation applicable to PIMCO Advisors, except as have been obtained under the Act, the Investment Company Act or the Advisers Act and the rules and regulations thereunder.

No opinion is expressed in this paragraph 4 as to the application of
Section 548 of the federal Bankruptcy Code and comparable provisions of state or foreign law or of any antifraud, antitrust or trade regulation laws. No opinion is expressed in this paragraph 4 with respect to the operating licenses necessary for PIMCO Advisors' businesses.

5. PIMCO Advisors is duly registered as an investment adviser under the Advisers Act and is not prohibited by the Advisers Act, the Investment Company Act or the rules and regulations thereunder from acting as investment adviser for the Fund as contemplated by the Investment Management Agreement, the Registration Statement and the Prospectus.

6. The description of PIMCO Advisors and its business, and the statements attributable to PIMCO Advisors, set forth in the Registration Statement or the Prospectus under the headings "Prospectus Summary - Investment Manager", "Management of the Fund" and "Investment Manager and Portfolio Manager" do not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading.

7. There is no action, suit or proceeding before or by any court, commission, regulatory body, administrative agency or other governmental agency or body, foreign or domestic, now pending or, to my knowledge, threatened against PIMCO Advisors of a nature required to be disclosed in the Registration Statement or Prospectus or that might reasonably result in any material adverse change in the ability of PIMCO Advisors to fulfill its obligations under either the Investment Management Agreement or the Portfolio Management Agreement.


The opinions expressed in paragraph 3 above are subject to the following limitations, qualifications and exceptions:

(a) the effect of bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights or remedies of creditors generally;

(b) the effect of general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought;

(c) the unenforceability under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and

(d) the unenforceability of any provision requiring the payment of attorney's fees, except to the extent that a court determines such fees to be reasonable.

In rendering the opinions expressed in paragraph 4 insofar as they require interpretation of the Material Agreements (i) I have assumed with your permission that all courts of competent jurisdiction would enforce such agreements as written but would apply the internal laws of the State of New York without giving effect to any choice of law provisions contained therein or any choice of law principles which would result in application of the internal laws of any other state and (ii) to the extent that any questions of legality or legal construction have arisen in connection with my review, I have applied the laws of the State of New York in resolving such questions. I advise you that certain of the Material Agreements may be governed by other laws, that such laws may vary substantially from the law assumed to govern for purposes of this opinion, and that this opinion may not be relied upon as to whether or not a breach or default would occur under the law actually governing such Material Agreements.

To the extent that the obligations of PIMCO Advisors may be dependent upon such matters, I assume for purposes of this opinion that: (i) all parties to the Transaction Documents other than PIMCO Advisors are duly incorporated or organized, validly existing and in good standing under the laws of their respective jurisdictions of incorporation or organization; (ii) all parties to the Transaction Documents other than PIMCO Advisors have the requisite power and authority and, in the case of natural persons, legal capacity to execute and deliver the Transaction Documents and to perform their respective obligations under the Transaction Documents to which they are a party; and (iii) the Transaction Documents to which such parties other than PIMCO Advisors are a party have been duly authorized, executed and delivered by such parties and, other than PIMCO Advisors, constitute their legally valid and binding obligations, enforceable against them in accordance with their terms. I express no opinion as to compliance by any parties to the Transaction Documents with any state or federal laws or regulations applicable to the subject transactions because of the nature of their business and I


express no opinion as to compliance by any parties to the Transaction Documents with any foreign laws or regulations applicable to the transactions contemplated by the Transaction Documents or which may affect the Transaction Documents' enforceability.

This opinion is rendered only to you and is solely for your benefit in connection with the transactions covered hereby. This opinion may not be relied upon by you for any other purpose, or furnished to, quoted to or relied upon by any other person, firm or corporation for any purpose, without my prior written consent.

Very truly yours,

Re: Pacific Investment Management Company LLC

Ladies and Gentlemen:

I am the Chief Legal Officer of PIMCO Advisors Fund Management LLC, a Delaware limited liability company ("PIMCO Advisors"). PIMCO Advisors is an affiliate of and under common control with Pacific Investment Management Company LLC, a Delaware limited liability company ("PIMCO"). In my capacity as Chief Legal Officer of PIMCO Advisors, I am rendering this opinion on behalf of PIMCO in connection with the issuance and sale to you today by PIMCO High Income Fund, a voluntary association with transferable shares organized and existing under and by virtue of the laws of The Commonwealth of Massachusetts (commonly referred to as a Massachusetts business trust) (the "Fund"), of 7,200 Auction Rate Cumulative Preferred Shares, Series M, 7,200 Auction Rate Cumulative Preferred Shares, Series T, 7,200 Auction Rate Cumulative Preferred Shares, Series W, 7,200 Auction Rate Cumulative Preferred Shares, Series TH, and 7,200 Auction Rate Cumulative Preferred Shares, Series F, of the Fund (the "Preferred Shares"), pursuant to a registration statement on Form N-2 under the Securities Act of 1933, as amended (the "Act"), and the Investment Company Act of 1940, as amended (the "Investment Company Act"), filed with the Securities and Exchange Commission (the "Commission") on May 1, 2003 (Act File No. 333-104915, and Investment Company Act File No. 811-21311), as amended by Pre-Effective Amendment No. 1 filed with the Commission on June 16, 2003, and Pre-Effective Amendment No. 2 filed with the Commission on June __, 2003 (such registration statement, as amended, referred to herein as the "Registration Statement"), and


an underwriting agreement dated June __, 2003, by and among you, the Fund and PIMCO Advisors (the "Underwriting Agreement") relating to the issuance and sale by the Fund of the Preferred Shares.

This opinion is rendered to you pursuant to Section 9(d) of the Underwriting Agreement. Capitalized terms used herein without definition have the meanings assigned to them in the Underwriting Agreement.

As such legal officer, I have examined such matters of fact and questions of law as I have considered appropriate for purposes of rendering the opinions expressed below, except where a statement is qualified as to knowledge or awareness, in which case I have made no or limited inquiry as specified below. I have examined, among other things, that certain Portfolio Management Agreement by and between PIMCO and PIMCO Advisors, as accepted and agreed to by the Fund, dated as of April 8, 2003 (the "Portfolio Management Agreement").

In my examination, I have assumed the genuineness of all signatures (other than those of officers of PIMCO on the Portfolio Management Agreement), the authenticity of all documents submitted to me as originals, and the conformity to authentic original documents of all documents submitted to me as copies.

I have been furnished with, and with your consent have relied upon, certificates of officers of PIMCO with respect to certain factual matters. In addition, I have obtained and relied upon such certificates and assurances from public officials as I have deemed necessary.

I am opining herein as to the effect of the federal laws of the United States, the internal laws of the State of New York and the internal laws of the State of Delaware, and I express no opinion with respect to the applicability thereto, or the effect thereon, of the laws of any other jurisdiction or country or as to any matters of municipal law or the laws of any other local agencies within any state or country. My opinions set forth in paragraph 4 below are based upon my consideration of only those statutes, rules and regulations which, in my experience, are normally applicable to transactions similar to those contemplated by the Portfolio Management Agreement, generally.

Whenever a statement herein is qualified by "to my knowledge" or a similar phrase, it is intended to indicate that I do not have current actual knowledge of the inaccuracy of such statement. However, except as otherwise expressly indicated, I have not undertaken any independent investigation to determine the accuracy of any such statement, and no inference that I have any knowledge of any matters pertaining to such statement should be drawn from my position as Chief Legal Officer of PIMCO Advisors.

Subject to the foregoing and the other matters set forth herein, it is my opinion that, as of the date hereof:


1. PIMCO is a limited liability company and is validly existing and in good standing under the Delaware Limited Liability Company Act (6 Del. C ss.. 18-101, et seq.) with all necessary limited liability company power and authority to enter into and deliver the Portfolio Management Agreement and perform its obligations thereunder and to carry on its business as it is now being conducted and as described in the Registration Statement. Based solely on certificates from public officials dated ________, 2003, and ________, 2003, respectively, I confirm that PIMCO is qualified to do business in the following States: California and New York, such States being those in which its ownership or leasing of property or its conducting of business may require such qualification and where failure to so qualify would have a material adverse effect on the ability of PIMCO to perform its obligations under the Portfolio Management Agreement.

2. The execution, delivery and performance of the Portfolio Management Agreement by PIMCO have been duly authorized by all necessary limited liability company action of PIMCO and no other actions on the part of PIMCO or its unitholders or any subsidiary of PIMCO or its unitholders is necessary to authorize and consummate the transactions contemplated thereby, and the Portfolio Management Agreement has been duly executed and delivered by PIMCO.

3. The Portfolio Management Agreement constitutes a legally valid and binding agreement of PIMCO, enforceable against PIMCO in accordance with its terms.

4. Neither the execution and delivery of the Portfolio Management Agreement by PIMCO, nor the consummation by PIMCO of transactions contemplated thereby, nor compliance by PIMCO with any of the terms and provisions thereof will:

(i) violate any provision of the limited liability company agreement of PIMCO, effective May 5, 2000, which is still in full force and effect and which has not been amended or supplemented through the date hereof,

(ii) violate any federal, Delaware or New York statute, rule or regulation applicable to PIMCO (other than federal and state securities or blue sky laws, the Investment Company Act and the Investment Advisers Act of 1940, as amended (the "Advisers Act"), as to which I express no opinion),

(iii) violate any agreement to which PIMCO is a party or by which it is bound and which is material to PIMCO's businesses taken as a whole (the "Material Agreements"),

(iv) violate any order, writ, injunction or decree, known to me and applicable to PIMCO, or


(v) to the best of my knowledge, require any consents, approvals, authorizations, registrations, declarations or filings by PIMCO under any federal or Delaware statute, rule or regulation applicable to PIMCO, except as have been obtained under the Act, the Investment Company Act or the Advisers Act and the rules and regulations thereunder.

No opinion is expressed in this paragraph 4 as to the application of
Section 548 of the federal Bankruptcy Code and comparable provisions of state or foreign law or of any antifraud, antitrust or trade regulation laws. No opinion is expressed in this paragraph 4 with respect to the operating licenses necessary for PIMCO's businesses.

5. PIMCO is duly registered as an investment adviser under the Advisers Act and is not prohibited by the Advisers Act, the Investment Company Act or the rules and regulations thereunder from acting as investment sub-adviser for the Fund as contemplated by the Portfolio Management Agreement, the Registration Statement and the Prospectus.

6. The description of PIMCO and its business, and the statements attributable to PIMCO, set forth in the Registration Statement or the Prospectus under the headings "Prospectus Summary - Portfolio Manager", "Management of the Fund" and "Investment Manager and Portfolio Manager" do not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein (in the case of the Prospectus, in light of the circumstances under which they were made) not misleading.

7. There is no action, suit or proceeding before or by any court, commission, regulatory body, administrative agency or other governmental agency or body, foreign or domestic, now pending or, to my knowledge, threatened against PIMCO of a nature required to be disclosed in the Registration Statement or Prospectus or that might reasonably result in any material adverse change in the ability of PIMCO to fulfill its obligations under the Portfolio Management Agreement.

The opinions expressed in paragraph 3 above are subject to the following limitations, qualifications and exceptions:

(a) the effect of bankruptcy, insolvency, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights or remedies of creditors generally;

(b) the effect of general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought;


(c) the unenforceability under certain circumstances under law or court decisions of provisions providing for the indemnification of or contribution to a party with respect to a liability where such indemnification or contribution is contrary to public policy; and

(d) the unenforceability of any provision requiring the payment of attorney's fees, except to the extent that a court determines such fees to be reasonable.

In rendering the opinions expressed in paragraph 4 insofar as they require interpretation of the Material Agreements (i) I have assumed with your permission that all courts of competent jurisdiction would enforce such agreements as written but would apply the internal laws of the State of New York without giving effect to any choice of law provisions contained therein or any choice of law principles which would result in application of the internal laws of any other state and (ii) to the extent that any questions of legality or legal construction have arisen in connection with my review, I have applied the laws of the State of New York in resolving such questions. I advise you that certain of the Material Agreements may be governed by other laws, that such laws may vary substantially from the law assumed to govern for purposes of this opinion, and that this opinion may not be relied upon as to whether or not a breach or default would occur under the law actually governing such Material Agreements.

To the extent that the obligations of PIMCO may be dependent upon such matters, I assume for purposes of this opinion that: (i) all parties to the Portfolio Management Agreement other than PIMCO are duly incorporated or organized, validly existing and in good standing under the laws of their respective jurisdictions of incorporation or organization; (ii) all parties to the Portfolio Management Agreement other than PIMCO have the requisite power and authority and, in the case of natural persons, legal capacity to execute and deliver the Portfolio Management Agreement and to perform their respective obligations under the Portfolio Management Agreement; and (iii) the Portfolio Management Agreement has been duly authorized, executed and delivered by such parties other than PIMCO and, other than PIMCO, constitute their legally valid and binding obligations, enforceable against them in accordance with their terms. I express no opinion as to compliance by any parties to the Portfolio Management Agreement with any state or federal laws or regulations applicable to the subject transactions because of the nature of their business and I express no opinion as to compliance by any parties to the Portfolio Management Agreement with any foreign laws or regulations applicable to the transactions contemplated by the Portfolio Management Agreement or which may affect the Portfolio Management Agreement's enforceability.

This opinion is rendered only to you and is solely for your benefit in connection with the transactions covered hereby. This opinion may not be relied upon by you for any other purpose, or furnished to, quoted to or relied upon by any other person, firm or corporation for any purpose, without my prior written consent.

Very truly yours,

II. OFFERING MATERIALS

2.1. Registered Offerings. In the case of an Offering that will be registered in whole or in part (a "Registered Offering") under the United States Securities Act of 1933, as amended (the "1933 Act"), you understand that the Issuer has filed with the Securities and Exchange Commission (the "Commission") a registration statement including a prospectus relating to the Securities. The term "Registration Statement" means such registration statement as amended or deemed to be amended to the effective date of the Underwriting Agreement and, in the event that the Issuer files an abbreviated registration statement to register additional Securities pursuant to Rule 462(b) under the 1933 Act, such abbreviated registration statement. The term "Prospectus" means the prospectus, together with the final prospectus supplement, if any, relating to the Offering first used to confirm sales of Securities and, in the case of a Registered Offering that is an International Offering, the term "Prospectus" shall mean, collectively, each prospectus or offering circular, together with each final prospectus supplement or final offering circular supplement, if any, relating to the Offering, in the respective forms first used or made available for use to confirm sales of Securities.

2.2. Unregistered Offerings. In the case of an Offering other than a Registered Offering, you understand that no registration statement has been filed with the Commission. The term "Offering Circular" means an offering circular or memorandum, if any, or any other written materials authorized by the Issuer to be used in connection with an Offering that is not a Registered Offering. The term "Preliminary Offering Circular" means any preliminary offering circular or memorandum, if any, or any other written preliminary materials authorized by the Issuer to be used in connection with such an Offering. As used herein, the terms "Offering Circular" and "Preliminary Offering Circular" shall include the material, if any, incorporated by reference therein. We will either, as soon as practicable after the later of the date of the Invitation Wire or the date made available to us by the Issuer, furnish to you (or make available for your review in our office) a copy of any Preliminary Offering Circular or any proof or draft of the Offering Circular. In any event, in any Offering involving an Offering Circular, the Manager will furnish to you, or make arrangements for you to obtain, as soon as practicable after sufficient quantities thereof are made available by the Issuer, copies of the final Offering Circular, as amended or supplemented, if applicable (but excluding for this purpose documents incorporated therein by reference).

III. MANAGER'S AUTHORITY

3.1. Authority of Manager to Determine Form of Documents, Terms of Offering, Etc. You authorize the Manager to act as lead manager of the Offering of the Securities by the Underwriters (the "Underwriters' Securities") or by the Issuer or Seller pursuant to delayed delivery contracts (the "Contract Securities"), if any, contemplated by the Underwriting Agreement. You authorize the Manager, on your behalf, (a) to determine the form of the Underwriting Agreement, (b) to execute and deliver the Underwriting Agreement to the Issuer, Guarantor or Seller, (c) to determine the form of any agreement or agreements between or among the syndicates participating in the International Offering of which the Offering is a part (each an "Intersyndicate Agreement"), and (d) to execute and deliver any such Intersyndicate Agreement. You authorize the Manager
(i) to exercise any Over-allotment Option for the purchase any of or all the Additional Securities for the accounts of the several Underwriters pursuant to the Underwriting Agreement, (ii) to agree, on your behalf and on behalf of the Co-Managers, to any addition to, change in or waiver of any provision of, or the termination of, the Underwriting Agreement or any Intersyndicate Agreement (other than an increase in the Purchase Price or in your Original Purchase Obligation to purchase Securities, in either case from that contemplated by the applicable AAU), (iii) to add or remove prospective Underwriters to or from the syndicate, (iv) to exercise, in the Manager's discretion, all the authority vested in the Manager in the Underwriting Agreement and (v) except as described below in this Section 3.1, to take any other action as may seem advisable to the Manager in respect of the Offering (including, without limitation, actions and communications with the Commission, the National Association of Securities Dealers, Inc. (the "NASD"), state blue sky or securities

4

commissions, stock exchanges and other regulatory bodies or organizations). If, in accordance with the terms of the applicable AAU, the Offering of the Securities is at varying prices based on prevailing market prices or prices related to prevailing market prices or at negotiated prices, you authorize the Manager to determine, on your behalf in the Manager's discretion, any Offering Price and the Fees and Commissions applicable to the Offering from time to time. You authorize the Manager on your behalf to arrange for any currency transactions (including forward and hedging currency transactions) as the Manager deems necessary to facilitate settlement of the purchase of the Securities, but you do not authorize the Manager on your behalf to engage in any other forward or hedging transactions in connection with the Offering unless such transactions are specified in an applicable AAU or are otherwise consented to by you. You further authorize the Manager, subject to the provisions of
Section 1.2 hereof, (i) to vary the offering terms of the Securities in effect at any time, including, if applicable, the Offering Price and Fees and Commissions set forth in the applicable AAU, (ii) to determine, on your behalf, the Purchase Price and (iii) to increase or decrease the number, amount or percentage of Securities being offered. Notwithstanding the foregoing provisions of this Section 3.1, the Manager shall notify the Underwriters, prior to the signing of the Underwriting Agreement, of any provision in the Underwriting Agreement that could result in an increase in the amount or percentage of Firm Securities set forth opposite each Underwriter's name in the Underwriting Agreement by more than 25% (or such other percentage as shall have been specified in the applicable Invitation Wire or otherwise consented to by you) as a result of the failure or refusal of another Underwriter or Underwriters to perform its or their obligations thereunder.

3.2. Offering Date. The Offering is to be made as soon after the Underwriting Agreement is entered into by the Issuer, Guarantor or Seller and the Manager as in the Manager's judgment is advisable, on the terms and conditions set forth in the Prospectus or the Offering Circular, as the case may be, and the applicable AAU. You agree not to sell any Securities prior to the time the Manager releases such Securities for sale to purchasers. The date on which such Securities are released for sale is referred to herein as the "Offering Date".

3.3. Advertising; Supplemental Offering Material. Any public advertisement of the Offering shall be made by the Manager on behalf of the Underwriters on such date as the Manager shall determine. You agree not to advertise the Offering prior to the date of the Manager's advertisement thereof without the Manager's consent. If the offering is made in whole or in part in reliance on Rule 144A (or upon another exemption from registration), you agree not to engage in any general solicitation and to abide by any other restrictions in the AAU or the Underwriting Agreement in connection therewith relating to any advertising or publicity. Any advertisement you may make of the Offering after such date will be your own responsibility and at your own expense and risk. In addition to your agreement to comply with restrictions on the Offering pursuant to Sections 10.10 and 10.11 hereof, you also agree that you will not, in connection with the offer and sale of the Securities in the Offering, without the consent of the Manager, give to any prospective purchaser of the Securities or other person not in your employ any written information concerning the Offering, the Issuer, the Guarantor or the Seller, other than information contained in any

5

Preliminary Prospectus, Prospectus, Preliminary Offering Circular or Offering Circular or in any computational materials ("Computational Materials") or other offering materials prepared by or with the consent of the Manager for use by the Underwriters in connection with the Offering and, in the case of a Registered Offering, filed with the Commission or the NASD, as applicable (the "Supplemental Offering Materials"). You further agree to cease distribution of any Computational Materials on the Offering Date.

3.4. Institutional and Retail Sales. You authorize the Manager to sell to institutions or retail purchasers such Securities purchased by you pursuant to the Underwriting Agreement as the Manager shall determine. The Selling Concession on any such sales shall be credited to the accounts of the Underwriters as the Manager shall determine.

3.5. Sales to Dealers. You authorize the Manager to sell to Dealers (as defined below) such Securities purchased by you pursuant to the Underwriting Agreement as the Manager shall determine. A "Dealer" shall be a person who is (a) a broker or dealer (as defined in the By-Laws of the NASD) actually engaged in the investment banking or securities business and (i) a member in good standing of the NASD or (ii) a foreign bank, broker, dealer or other institution not eligible for membership in the NASD that, in the case of either clause (a)(i) or (a)(ii), makes the representations and agreements applicable to such institutions contained in Section 10.6 hereof or (b) in the case of Offerings of Securities that are exempt securities under Section 3(a)(12) of the Securities Exchange Act of 1934, as amended (the "1934 Act"), and such other Securities as from time to time may be sold by a "bank" (as defined in Section 3(a)(6) of the 1934 Act (a "Bank")), a Bank that is not a member of the NASD and that makes the representations and agreements applicable to such institutions contained in Section 10.6 hereof. If the price for any such sales by the Manager to Dealers exceeds an amount equal to the Offering Price less the Selling Concession set forth in the applicable AAU, the amount of such excess, if any, shall be credited to the accounts of the Underwriters as the Manager shall determine.

3.6. Direct Sales. The Manager will advise you promptly, on the date of the Offering, as to the Securities purchased by you pursuant to the Underwriting Agreement that you shall retain for direct sale. At any time prior to the termination of the applicable AAU, any such Securities that are held by the Manager for sale but not sold, may, on your request and at the Manager's discretion, be released to you for direct sale, and Securities so released to you shall no longer be deemed held for sale by the Manager. You may allow, and Dealers may reallow, a discount on sales to Dealers in an amount not in excess of the Reallowance set forth in the applicable AAU. You may not purchase Securities from, or sell Securities to, any other Underwriter or Dealer at any discount or concession other than the Reallowance, except with the consent of the Manager.

3.7. Release of Unsold Securities. From time to time prior to the termination of the applicable AAU, on the request of the Manager, you shall advise the Manager of the amount of Securities remaining unsold which were retained by or released to you for direct sale and of the amount of Securities and Other Securities (as

6

defined below) purchased for your account remaining unsold which were delivered to you pursuant to Article V hereof or pursuant to any Intersyndicate Agreement, and, on the request of the Manager, you shall release to the Manager any such Securities and Other Securities remaining unsold (i) for sale by the Manager to institutions, Dealers or retail purchasers, (ii) for sale by the Issuer or Seller pursuant to delayed delivery contracts or (iii) if, in the Manager's opinion, such Securities or Other Securities are needed to make delivery against sales made pursuant to Article V hereof or any Intersyndicate Agreement.

3.8. International Offerings. In the case of an International Offering, you authorize the Manager (i) to make representations on your behalf as set forth in any Intersyndicate Agreement or Underwriting Agreement and (ii) to purchase or sell for your account pursuant to the Intersyndicate Agreement
(a) Securities, (b) any other securities of the same class and series, or any securities into which the Securities may be converted or for which the Securities may be exchanged or exercised and (c) any other securities designated in the applicable AAU or applicable Intersyndicate Agreement (the securities referred to in clauses (b) and (c) above being referred to collectively as the "Other Securities").

IV. DELAYED DELIVERY CONTRACTS

4.1. Arrangements for Sales. You agree that arrangements for sales of Contract Securities will be made only through the Manager acting either directly or through Dealers (including Underwriters acting as Dealers), and you authorize the Manager to act on your behalf in making such arrangements. The aggregate amount of Securities to be purchased by the several Underwriters shall be reduced by the respective amounts of Contract Securities attributed to such Underwriters as hereinafter provided. Subject to the provisions of Section 4.2, the aggregate amount of Contract Securities shall be attributed to the Underwriters as nearly as practicable in their respective Underwriting Percentages, except that, as determined by the Manager in its discretion, (i) Contract Securities directed and allocated by a purchaser to specific Underwriters shall be attributed to such Underwriters and (ii) Contract Securities for which arrangements have been made for sale through Dealers shall be attributed to each Underwriter approximately in the proportion that Securities of such Underwriter held by the Manager for sales to Dealers bear to all Securities so held. The fee with respect to Contract Securities payable to the Manager for the accounts of the Underwriters pursuant to the Underwriting Agreement shall be credited to the accounts of the respective Underwriters in proportion to the Contract Securities attributed to such Underwriters pursuant to the provisions of this Section 4.1, less, in the case of each Underwriter, the concession to Dealers on Contract Securities sold through Dealers and attributed to such Underwriter.

4.2. Excess Sales. If the amount of Contract Securities attributable to an Underwriter pursuant to Section 4.1 would exceed such Underwriter's Original Purchase Obligation reduced by the amount of Underwriters' Securities sold by or on behalf of such Underwriter, such excess shall not be attributed to such Underwriter, and such Underwriter shall be regarded as having acted only as a Dealer with respect to, and shall receive only the concession to Dealers on, such excess.

7

V. PURCHASE AND SALE OF SECURITIES; FACILITATION OF DISTRIBUTION

5.1. Purchase and Sale of Securities; Facilitation of Distribution. In order to facilitate the distribution and sale of the Securities, you authorize the Manager to buy and sell Securities and any Other Securities, in addition to Securities sold pursuant to Article III hereof, in the open market or otherwise (including, without limitation, pursuant to any Intersyndicate Agreement), for long or short account, on such terms as it shall deem advisable, and to over-allot in arranging sales. Such purchases and sales and over-allotments shall be made for the accounts of the several Underwriters as nearly as practicable in their respective Underwriting Percentages or, in the case of an International Offering, such purchases and sales shall be for such accounts as set forth in the applicable Intersyndicate Agreement. Any securities which may have been purchased by the Manager for stabilizing purposes in connection with the Offering prior to the execution of the applicable AAU shall be treated as having been purchased pursuant to this Section 5.1 for the accounts of the several Underwriters or, in the case of an International Offering, for such accounts as are set forth in the applicable Intersyndicate Agreement. Your net commitment pursuant to the foregoing authorization shall not exceed at the close of business on any day an amount equal to 20% of your Underwriting Percentage of the aggregate initial Offering Price of the Firm Securities, it being understood that, in calculating such net commitment, the initial Offering Price shall be used with respect to the Securities so purchased or sold and, in the case of all Other Securities, shall be the purchase price thereof. Your net commitment for short account (i.e., "naked short") shall be calculated by assuming that all Securities that may be purchased upon exercise of any over-allotment option then exercisable are acquired (whether or not actually acquired) and, in the case of an International Offering, after giving effect to the purchase of any Securities or Other Securities that the Manager has agreed to purchase for your account pursuant to any applicable Intersyndicate Agreement. On demand you shall take up and pay for any Securities or Other Securities so purchased for your account and any Securities released to you pursuant to Section 3.7 hereof and you shall deliver to the Manager against payment any Securities or Other Securities so sold or over-allotted for your account or released to you. The Manager agrees to notify you if it engages in any stabilization transaction requiring reports to be filed pursuant to Rule 17a-2 under the 1934 Act and to notify you of the date of termination of stabilization. You agree not to stabilize or engage in any syndicate covering transaction (as defined in Rule 100 of Regulation M under the 1934 Act ("Regulation M")) in connection with the Offering without the prior consent of the Manager. You further agree to provide to Salomon Smith Barney any reports required of you pursuant to Rule 17a-2 not later than the date specified therein and you authorize Salomon Smith Barney to file on your behalf with the Commission any reports required by such Rule.

If the limitations of Rule 101 of Regulation M ("Rule 101") do not apply to you with respect to the Securities, Other Securities or other reference securities (as defined in Rule 100 of Regulation M) because they satisfy the exception for actively-traded securities in subsection (c)(1) of Rule 101 or the exception for Rule 144A securities in

8

subsection (b)(10) of Rule 101, you agree that promptly upon notice from the Manager (or, if later, at the time stated in the notice) you will comply with Rule 101 as though such exception were not available but the other provisions of Rule 101 (as interpreted by the Commission and after giving effect to any applicable exemptions) did apply. If the securities in question are NASDAQ securities (as defined in Rule 100 of Regulation M) you may engage in passive market making in accordance with Rule 103 of Regulation M (except that the daily net purchase volume limitation will not apply and the maximum displayed bid size shall be 5,000 shares excluding transactions effected in the SOES system) unless the notice from the Manager also states that passive market making is not permitted.

5.2. Penalty With Respect to Securities Repurchased by the Manager. If pursuant to the provisions of Section 5.1 and prior to the termination of the Manager's authority to cover any short position incurred under the applicable AAU or such other date as the Manager shall specify in a Wire, either (A) the Manager purchases or contracts to purchase for the account of any Underwriter in the open market or otherwise any Securities which were retained by, or released to, you for direct sale or any Securities sold pursuant to Section 3.4 for which you received a portion of the Selling Concession set forth in the applicable AAU, or any Securities which may have been issued on transfer or in exchange for such Securities, and which Securities were therefore not effectively placed for investment or (B) if the Manager has advised you by Wire that trading in the Securities will be reported to the Manager pursuant to the "Initial Public Offering Tracking System" of The Depository Trust Company ("DTC") and the Manager determines, based on notices from DTC, that your customers sold an amount of Securities during any day that exceeds the amount previously notified to you by Wire, then you authorize the Manager either to charge your account with an amount equal to such portion of the Selling Concession set forth in the applicable AAU received by you with respect to such Securities or, in the case of clause (B), such Securities as exceed the amount specified in such Wire or to require you to repurchase such Securities or, in the case of clause (B), such Securities as exceed the amount specified in such Wire, at a price equal to the total cost of such purchase, including transfer taxes, accrued interest, dividends and commissions, if any.

5.3. Compliance with Regulation M. You represent that, at all times since you were invited to participate in the Offering, you have complied with the provisions of Regulation M applicable to such Offering, in each case as interpreted by the Commission and after giving effect to any applicable exemptions. If you have been notified in a Wire that the Underwriters may conduct passive market making in compliance with Rule 103 of Regulation M in connection with the Offering, you represent that, at all times since your receipt of such Wire, you have complied with the provisions of such Rule applicable to such Offering, as interpreted by the Commission and after giving effect to any applicable exemptions.

5.4. Standby Underwritings. You authorize the Manager in its discretion, at any time on, or from time to time prior to, the expiration of the conversion right of convertible securities identified in the applicable AAU in case of securities called for redemption, or the expiration of rights to acquire securities in the case of rights offerings, for which, in either case, standby underwriting arrangements have been

9

made: (i) to purchase convertible securities or rights to acquire Securities for your account, in the open market or otherwise, on such terms as the Manager determines and to convert convertible securities or exercise rights so purchased; and (ii) to offer and sell the underlying common stock or depositary shares for your account, in the open market or otherwise, for long or short account (for purposes of such commitment, such common stock or depositary shares being considered the equivalent of convertible securities or rights), on such terms consistent with the terms of the Offering set forth in the Prospectus or Offering Circular as the Manager determines. On demand you shall take up and pay for any securities so purchased for your account or you shall deliver to the Manager against payment any securities so sold, as the case may be. During such period you may offer and sell the underlying common stock or depositary shares, but only at prices set by the Manager from time to time, and any such sales shall be subject to the Manager's right to sell to you the underlying common stock or depositary shares as above provided and to the Manager's right to reserve your Securities purchased, received or to be received upon conversion. You agree not to bid for, purchase, attempt to induce others to purchase, or sell, directly or indirectly, any convertible securities or rights or underlying common stock or depositary shares, provided, however, that no Underwriter shall be prohibited from (a) selling underlying common stock owned beneficially by such Underwriter on the day the convertible securities were first called for redemption, (b) converting convertible securities owned beneficially by such Underwriter on such date or selling underlying common stock issued upon conversion of convertible securities so owned, (c) exercising rights owned beneficially by such Underwriter on the record date for a rights offering or selling the underlying common stock or depositary shares issued upon exercise of rights so owned or (d) purchasing or selling convertible securities or rights or underlying common stock or depositary shares as a broker pursuant to unsolicited orders.

VI. PAYMENT AND SETTLEMENT

6.1. Payment and Settlement. You shall deliver to the Manager on the date and at the place and time specified in the applicable AAU (or on such later date and at such place and time as may be specified by the Manager in a subsequent Wire) the funds specified in the applicable AAU, payable to the order of Salomon Smith Barney Inc., for (i) an amount equal to the Offering Price plus (if not included in the Offering Price) accrued interest, amortization of original issue discount or dividends, if any, specified in the Prospectus or Offering Circular, less the applicable Selling Concession in respect of the Firm Securities to be purchased by you, (ii) an amount equal to the Offering Price plus (if not included in the Offering Price) accrued interest, amortization of original issue discount or dividends, if any, specified in the Prospectus or Offering Circular, less the applicable Selling Concession in respect of such of the Firm Securities to be purchased by you as shall have been retained by or released to you for direct sale as contemplated by Section 3.6 hereof or (iii) the amount set forth or indicated in the applicable AAU, as the Manager shall advise. You shall make similar payment as the Manager may direct for Additional Securities, if any, to be purchased by you on the date specified by the Manager for such payment. The Manager will make payment to the Issuer or Seller against delivery to the Manager for your account of the Securities to be purchased by you, and the Manager will deliver to you the Securities

10

paid for by you which shall have been retained by or released to you for direct sale. If the Manager determines that transactions in the Securities are to be settled through the facilities of DTC or other clearinghouse facility, payment for and delivery of Securities purchased by you shall be made through such facilities, if you are a member, or, if you are not a member, settlement shall be made through your ordinary correspondent who is a member.

VII. EXPENSES

7.1. Management Fee. You authorize the Manager to charge your account as compensation for the Manager's and Co-Managers' services in connection with the Offering, including the purchase from the Issuer or Seller of the Securities, as the case may be, and the management of the Offering, the amount, if any, set forth as the management fee, global coordinators fee, praecipium or other similar fee in the applicable AAU. Such amount shall be divided among the Manager and any Co-Managers named in the applicable AAU as they may determine.

VIII. MANAGEMENT OF SECURITIES AND FUNDS

8.1. Advances; Loans; Pledges. You authorize the Manager to advance the Manager's own funds for your account, charging current interest rates, or to arrange loans for your account for the purpose of carrying out the provisions of the applicable AAU and any Intersyndicate Agreement and in connection therewith, to hold or pledge as security therefor all or any securities which the Manager may be holding for your account under the applicable AAU and any Intersyndicate Agreement, to execute and deliver any notes or other instruments evidencing such advances or loans and to give all instructions to the lenders with respect to any such loans and the proceeds thereof. The obligations of the Underwriters under loans arranged on their behalf shall be several in proportion to their respective Original Purchase Obligations and not joint. Any lender is authorized to accept the Manager's instructions as to the disposition of the proceeds of any such loans. In the event of any such advance or loan, repayment thereof shall, in the discretion of the Manager, be effected prior to making any remittance or delivery pursuant to Section 8.2, 8.3 or 9.2 hereof.

8.2. Return of Amount Paid for Securities. Out of payment received

The Manager may deliver to you from time to time prior to the termination of the applicable AAU pursuant to Section 9.1 hereof against payment, for carrying purposes only, any Securities or Other Securities purchased by you under the applicable AAU or any Intersyndicate Agreement which the Manager is holding for sale for your account but which are not sold and paid for. You shall redeliver to the Manager against payment any Securities or Other Securities delivered to you for carrying purposes at such times as the Manager may demand.

IX. TERMINATION; INDEMNIFICATION

9.1. Termination. Each AAU shall terminate at the close of business on the later of the date on which the Underwriters pay the Issuer or Seller for the Securities and 45 full days after the applicable Offering Date, unless sooner terminated by the Manager. The Manager may in its discretion by notice to you prior to the termination of such AAU alter any of the terms or conditions of the Offering to the extent permitted by Articles III or IV hereof, or terminate or suspend the effectiveness of Article V hereof, or any part thereof. No termination or suspension pursuant to this paragraph shall affect the Manager's authority under Section 3.1 hereof to take actions in respect of the Offering or under Article V hereof to cover any short position incurred under such AAU or in connection with covering any such short position to require you to repurchase Securities as specified in Section 5.2 hereof.

9.2. Delivery or Sale of Securities; Settlement of Accounts. Upon termination of each AAU or prior thereto at the Manager's discretion, the Manager shall deliver to you any Securities paid for by you pursuant to Section 6.1 hereof and held by the Manager for sale pursuant to Section 3.4 or 3.5 hereof but not sold and paid for and any Securities or Other Securities that are held by the Manager for your account pursuant to the provisions of Article V hereof or any Intersyndicate Agreement. Notwithstanding the foregoing, at the termination of such AAU, if the aggregate initial Offering Price of any such Securities and the aggregate purchase price of any Other Securities so held and not sold and paid for does not exceed an amount equal to 20% of the aggregate initial Offering Price of the Securities, the Manager may, in its discretion, sell such Securities and Other Securities for the accounts of the several Underwriters, at such prices, on such terms, at such times and in such manner as it may determine. Within the period specified by applicable NASD Rules or, if no period is so specified, as soon as practicable after termination of such AAU, your account shall be settled and paid. The Manager may reserve from distribution such amount as the Manager deems advisable to cover possible additional expenses. The determination by the Manager of the amount so to be paid to or by you shall be final and conclusive. Any of your funds in the Manager's hands may be held with the Manager's general funds without accountability for interest

12

Notwithstanding any provision of this Master AAU other than Section 10.12, upon termination of each AAU or prior thereto at the Manager's discretion, the Manager (i) may allocate to the accounts of the Underwriters the expenses described in Section 7.2 hereof and any losses incurred upon the sale of Securities or Other Securities pursuant to the applicable AAU or any Intersyndicate Agreement (including any losses incurred upon the sale of securities referred to in Section 5.4(ii) hereof), (ii) may deliver to the Underwriters any unsold Securities or Other Securities purchased pursuant to
Section 5.1 hereof or any Intersyndicate Agreement and (iii) may deliver to the Underwriters any unsold Securities purchased pursuant to the applicable Underwriting Agreement, in each case in the Manager's discretion. The Manager shall have full discretion to allocate expenses and Securities to the accounts of any Underwriter as the Manager decides, except that (a) no Underwriter (other than the Manager or a Co-Manager) shall bear more than its share of such expenses, losses or Securities (such share shall not exceed such Underwriter's Underwriting Percentage and shall be determined pro rata among all such Underwriters based on their Underwriting Percentages), (b) no such Underwriter shall receive Securities that, together with any Securities purchased by such Underwriter pursuant to Section 6.1 (but excluding any Securities that such Underwriter is required to repurchase pursuant to Section 5.2) exceed such Underwriter's Original Purchase Obligation and (c) no Co-Manager shall bear more than its share, as among the Manager and the other Co-Managers, of such expenses, losses or Securities (such share to be determined pro rata among the Manager and all Co-Managers based on (1) their relative Underwriting Percentages as a percentage of the total combined Underwriting Percentages of the Manager and all Co-Managers, or (2) if the Manager so determines, their relative Offering Economics (as hereinafter defined) as a percentage of the combined Offering Economics of the Manager and all Co-Managers together. The Manager's or a Co-Manager's "Offering Economics" equals the sum of its Management Fee Share, its Underwriting Fee Share and its Selling Concession Share (each as hereinafter defined). The Manager's or a Co-Manager's "Management Fee Share" is the dollar amount of its share, as agreed among the Manager and any Co-Managers, of the amount payable by all Underwriters to some or all of the Manager and any Co-Manager as a global coordinators' fee, praecipium, management fee or other fee. The Manager's or a Co-Manager's "Underwriting Fee Share" is the dollar amount of its Underwriting Percentage of the aggregate initial Offering Price of the Firm Securities less the Purchase Price thereof, less the Selling Concession thereon. The Manager's or a Co-Manager's "Selling Concession Share" is the dollar amount of any Selling Concession credited to it on sales from the institutional pot or on sales made for the account of any other Underwriter. If any Securities or Other Securities returned to you pursuant to clause (ii) or
(iii) above were not paid for by you pursuant to Section 6.1 hereof, you shall pay to the Manager an amount per security equal to the amount set forth in
Section 6.1(i), in the case of Securities returned to you pursuant to clause
(iii) above, or the purchase price of such securities, in the case of Securities or Other Securities returned to you pursuant to clause (ii) above.

9.3. Post-Settlement Expenses. Notwithstanding any settlement on the termination of the applicable AAU, you agree to pay any transfer taxes which may be assessed and paid after such settlement on account of any sales or transfers under such AAU or any Intersyndicate Agreement for your account and your Underwriting

13

Percentage of (i) all expenses incurred by the Manager in investigating, preparing to defend or defending against any action, claim or proceeding which is asserted or instituted by any party (including any governmental or regulatory body) relating to (a) the Registration Statement, any Preliminary Prospectus or Prospectus (or any amendment or supplement thereto), any Preliminary Offering Circular or Offering Circular (or any amendment or supplement thereto) or Supplemental Offering Materials, (b) the violation of any applicable restrictions on the offer, sale, resale or purchase of Securities or Other Securities imposed by United States Federal or state laws or foreign laws and the rules and regulations of any regulatory body promulgated thereunder or pursuant to the terms of such AAU, the Underwriting Agreement or any Intersyndicate Agreement or (c) any claim that the Underwriters constitute a partnership, an association or an unincorporated business or other separate entity and (ii) any liability, including attorneys' fees, incurred by the Manager in respect of any such action, claim or proceeding, whether such liability shall be the result of a judgment or arbitrator's determination or as a result of any settlement agreed to by the Manager, other than any such expense or liability as to which the Manager actually receives indemnity pursuant to
Section 9.4, contribution pursuant to Section 9.5, indemnity or contribution pursuant to the Underwriting Agreement or damages from an Underwriter for breach of its representations, warranties, agreements, or covenants contained in the applicable AAU. None of the foregoing provisions of this Section 9.3 shall relieve any defaulting or breaching Underwriter from liability for its defaults or breach.

9.4. Indemnification. You agree to indemnify and hold harmless each other Underwriter and each person, if any, who controls any such Underwriter within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, to the extent and upon the terms which you agree to indemnify and hold harmless any of the Issuer, the Guarantor, the Seller, any person controlling the Issuer, the Guarantor, the Seller, its directors and, in the case of a Registered Offering, its officers who signed the Registration Statement and, in the case of an Offering other than a Registered Offering, its officers, in each case as set forth in the Underwriting Agreement. You further agree to indemnify and hold harmless any investment banking firm identified in a Wire as the qualified independent underwriter as defined in Rule 2720 of the NASD's Conduct Rules ("QIU") for an Offering and each person, if any, who controls such QIU within the meaning of either Section 15 of the 1933 Act or Section 20 of the 1934 Act, from and against any and all losses, claims, damages and liabilities related to, arising out of or in connection with such investment banking firm's activities as QIU for the Offering. You agree with the other Underwriters to reimburse such QIU for all expenses, including fees and expenses of counsel as they are incurred, in connection with investigating, preparing for, or defending any action, claim or proceeding related to, arising out of, or in connection with such QIU's activities as a QIU for the Offering. Each Underwriter shall be responsible for its Underwriting Percentage of any amount due to such QIU on account of the foregoing indemnity. You agree that such QIU shall have no additional liability to any Underwriter or otherwise as a result of its serving as QIU in connection with the Offering. You further agree that to the extent the indemnification provided to a QIU under this Section 9.4 is unavailable to such QIU or insufficient in respect of any losses, claims, damages or liabilities (and expenses relating thereto), whether as a matter of law or public policy or as a result of the default of any Underwriter in performing its obligations under this Section 9.4, you and each other Underwriter shall

14

contribute to the amount paid or payable by such QIU as a result of such losses, claims, damages or liabilities (and expenses relating thereto) in proportion to your Underwriting Percentage.

9.5. Contribution. Notwithstanding any settlement on the termination of the applicable AAU, you agree to pay upon request of the Manager, as contribution, your Underwriting Percentage of any losses, claims, damages or liabilities, joint or several, paid or incurred by any Underwriter to any person other than an Underwriter, arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus or Prospectus (or any amendment or supplement thereto), any Preliminary Offering Circular or Offering Circular (or any amendment or supplement thereto) or Supplemental Offering Materials or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading (other than an untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with information furnished to the Company in writing by the Underwriter on whose behalf the request for contribution is being made expressly for use therein) and your Underwriting Percentage of any legal or other expenses reasonably incurred by the Underwriter (with the approval of the Manager) on whose behalf the request for contribution is being made in connection with investigating or defending any such loss, claim, damage or liability or any action in respect thereof; provided that no request shall be made on behalf of any Underwriter guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) from any Underwriter who was not guilty of such fraudulent misrepresentation. None of the foregoing provisions of this Section 9.5 shall relieve any defaulting or breaching Underwriter from liability for its defaults or breach.

9.6. Separate Counsel. If any claim is asserted or action or proceeding commenced pursuant to which the indemnity provided in Section 9.4 may apply, the Manager may take such action in connection therewith as it deems necessary or desirable, including retention of counsel for the Underwriters, and in its discretion separate counsel for any particular Underwriter or group of Underwriters, and the fees and disbursements of any counsel so retained shall be allocated among the several Underwriters as determined by the Manager. Any Underwriter may elect to retain at its own expense its own counsel and, on advice of such counsel but only with the consent of the Manager, may settle or consent to the settlement of any such claim, action or proceeding. The Manager may settle or consent to the settlement of any such claim, action or proceeding. Whenever the Manager receives notice of the assertion of any claim, action or proceeding to which the provisions of Section 9.4 would apply, it will give prompt notice thereof to each Underwriter, and whenever you receive notice of the assertion of any claim or commencement of any action or proceeding to which the provisions of Section 9.4 would apply, you will give prompt notice thereof to the Manager. The Manager also will furnish each Underwriter with periodic reports, at such times as it deems appropriate, as to the status of such claim, action or proceeding, and the action taken by it in connection therewith.

9.7. Survival of Agreements. Regardless of any termination of an AAU, your agreements contained in Article V and Sections 3.1, 9.3, 9.4, 9.5, 9.6 and

15

11.2 shall remain operative and in full force and effect regardless of (i) any termination of the Underwriting Agreement, (ii) any investigation made by or on behalf of any Underwriter or any person controlling any Underwriter or by or on behalf of the Issuer, the Guarantor, the Seller, its directors or officers or any person controlling the Issuer, the Guarantor or the Seller and (iii) acceptance of any payment for any Securities.

X. REPRESENTATIONS AND COVENANTS OF UNDERWRITERS

10.1. Knowledge of Offering. You understand that it is your responsibility to examine the Registration Statement, the Prospectus or the Offering Circular, as the case may be, relating to the Offering, any amendment or supplement thereto, any Preliminary Prospectus or Preliminary Offering Circular and the material, if any, incorporated by reference therein and any Supplemental Offering Materials and you will familiarize yourself with the terms of the Securities, any applicable Indenture and the other terms of the Offering thereof which are to be reflected in the Prospectus or the Offering Circular, as the case may be, and the applicable AAU and Underwriting Agreement. The Manager is authorized, with the advice of counsel for the Underwriters, to approve on your behalf any amendments or supplements to the Registration Statement and the Prospectus or the Offering Circular, as the case may be.

10.2. Distribution of Materials. You will keep an accurate record of the names and addresses of all persons to whom you give copies of the Registration Statement, the Prospectus, any Preliminary Prospectus (or any amendment or supplement thereto) or any Offering Circular or any Preliminary Offering Circular and, when furnished with any subsequent amendment to the Registration Statement, any subsequent Prospectus, any subsequent Offering Circular or any memorandum outlining changes in the Registration Statement or any Prospectus or Offering Circular, you will, upon request of the Manager, promptly forward copies thereof to such persons.

10.3. Accuracy of Underwriters' Information. You confirm that the information that you have given or are deemed to have given in response to the Underwriters' Questionnaire attached as Exhibit A hereto (and to any other questions addressed to you in the Invitation Wire or other Wires), which information has been furnished to the Issuer for use in the Registration Statement and the Prospectus or the Offering Circular, as the case may be, or has otherwise been relied upon in connection with the Offering, is complete and accurate. You shall notify the Manager immediately of any development before the termination of the applicable AAU which makes untrue or incomplete any information that you have given or are deemed to have given in response to the Underwriters' Questionnaire (or such other questions).

10.4. Name; Address. Unless you have promptly notified the Manager in writing otherwise, your name as it should appear in the Prospectus or the Offering Circular and any advertisement, if different, and your address are as set forth on the signature pages hereof.

16

requirements of Rule 15c3-1 under the 1934 Act or of any similar provision of any applicable rules of any securities exchange to which you are subject or, if you are a financial institution subject to regulation by the Board of Governors of the United States Federal Reserve System, the United States Comptroller of the Currency or the United States Federal Deposit Insurance Corporation, will not place you in violation of any applicable capital requirements or restrictions of such regulator or any other regulator to which you are subject.

10.6. Compliance with NASD Requirements. You represent that you are a member in good standing of the NASD, a Bank that is not a member of the NASD or a foreign bank or dealer not eligible for membership in the NASD. In making sales of Securities, if you are such a member, you agree to comply with all applicable interpretive material ("IM") and rules of the NASD, including, without limitation, IM-2110-1 (the NASD's interpretation with respect to free-riding and withholding) and Rule 2740 of the NASD's Conduct Rules, or, if you are such a foreign bank or dealer, you agree to comply, as applicable, with IM-2110-1 and Rules 2730, 2740 and 2750 of the NASD's Conduct Rules as though you were such a member and Rule 2420 of the NASD's Conduct Rules as it applies to a nonmember broker or dealer in a foreign country. If you are a Bank, you agree, to the extent required by applicable law or the Conduct Rules of the NASD, that you will not, in connection with the public offering of any Securities that do not constitute "exempted securities" within the meaning of
Section 3(a)(12) of the 1934 Act or such other Securities as from time to time may be sold by a Bank, purchase any Securities at a discount from the Offering Price from any Underwriter or dealer or otherwise accept any Fees and Commissions from any Underwriter or Dealer, and you agree to comply, as applicable, with Rule 2420 of the NASD's Conduct Rules as though you were a member.

10.7. Further State Notice. The Manager will file a Further State Notice with the Department of State of New York, if required.

10.8. Compliance with Rule 15c2-8. In the case of a Registered Offering and any other Offering to which the provisions of Rule 15c2-8 under the 1934 Act are made applicable pursuant to the AAU or otherwise, you agree to comply with such Rule in connection with the Offering. In the case of an Offering other than a Registered Offering, you agree to comply with applicable Federal and state laws and the applicable rules and regulations of any regulatory body promulgated thereunder governing the use and distribution of offering circulars by underwriters.

10.9. Discretionary Accounts. In the case of a Registered Offering of Securities issued by an Issuer that was not, immediately prior to the filing of the Registration Statement, subject to the requirements of Section 13(d) or 15(d) of the 1934 Act, you agree that you will not make sales to any account over which you exercise discretionary authority in connection with such sale except as otherwise permitted by the applicable AAU for such Offering.

10.10. Offering Restrictions. If you are a foreign bank or dealer and you are not registered as a broker-dealer under Section 15 of the 1934 Act, you agree that while you are acting as an Underwriter in respect of the Securities and in any event

17

during the term of the applicable AAU, you will not directly or indirectly effect in, or with persons who are nationals or residents of, the United States, its territories or possessions any transactions (except for the purchases provided for in the Underwriting Agreement and transactions contemplated by Articles III and V hereof) in Securities or any Other Securities.

It is understood that, except as specified in the applicable AAU, no action has been taken by the Manager, the Issuer, the Guarantor or the Seller to permit you to offer Securities in any jurisdiction other than the United States, in the case of a Registered Offering, where action would be required for such purpose.

10.11. Representations, Warranties and Agreements. You agree to make to each other Underwriter participating in an Offering the same representations, warranties and agreements, if any, made by the Underwriters to the Issuer, the Guarantor or the Seller in the applicable Underwriting Agreement or any Intersyndicate Agreement and you authorize the Manager to make such representations, warranties and agreements to the Issuer, the Guarantor or the Seller on your behalf.

10.12. Limitation on the Authority of the Manager to Purchase and Sell Securities for the Account of Certain Underwriters. Notwithstanding any provision of this AAU authorizing the Manager to purchase or sell any Securities or Other Securities (including arranging for the sale of Contract Securities) or over-allot in arranging sales of Securities for the accounts of the several Underwriters, the Manager may not, in connection with the Offering of any Securities, make any such purchases, sales and/or over-allotments for the account of any Underwriter that, not later than its acceptance of the Invitation Wire relating to such Offering, has advised the Manager that, due to its status as, or relationship to, a bank or bank holding company such purchases, sales and/or over-allotments are prohibited by applicable law. If any Underwriter so advises the Manager, the Manager may allocate any such purchases, sales and over-allotments (and the related expenses) which otherwise would have been allocated to your account based on your respective Underwriting Percentage to your account based on the ratio of your Original Purchase Obligation to the Original Purchase Obligations of all Underwriters other than the advising Underwriter or Underwriters or in such other manner as the Manager shall determine.

XI. DEFAULTING UNDERWRITERS

11.1. Effect of Termination. If the Underwriting Agreement is terminated as permitted by the terms thereof, your obligations hereunder with respect to the Offering of the Securities shall immediately terminate except (i) as set forth in Section 9.7, (ii) that you shall remain liable for your Underwriting Percentage (or such other percentage as may be specified pursuant to Section 9.2) of all expenses and for any purchases or sales which may have been made for your account pursuant to the provisions of Article V hereof or any Intersyndicate Agreement and (iii) that such termination shall not affect any obligations of any defaulting or breaching Underwriter.

18

11.2. Sharing of Liability. If any Underwriter shall default in its obligations (i) pursuant to Section 5.1, 5.2 or 5.4, (ii) to pay amounts charged to its account pursuant to Section 7.1, 7.2 or 8.1 or (iii) pursuant to Section 9.2, 9.3, 9.4, 9.5, 9.6 or 11.1, you will assume your proportionate share (determined on the basis of the respective Underwriting Percentages of the non-defaulting Underwriters) of such obligations, but no such assumption shall relieve any defaulting Underwriter from liability to the non-defaulting Underwriters, the Issuer, the Guarantor or the Seller for its default.

11.3. Arrangements for Purchases. The Manager is authorized to arrange for the purchase by others (including the Manager or any other Underwriter) of any Securities not purchased by any defaulting Underwriter in accordance with the terms of the applicable Underwriting Agreement or, if the applicable Underwriting Agreement does not provide arrangements for defaulting Underwriters, in the discretion of the Manager. If such arrangements are made, the respective amounts of Securities to be purchased by the remaining Underwriters and such other person or persons, if any, shall be taken as the basis for all rights and obligations hereunder, but this shall not relieve any defaulting Underwriter from liability for its default.

XII. MISCELLANEOUS

12.1. Obligations Several. Nothing contained in this Salomon Smith Barney Master AAU or any AAU constitutes you partners with the Manager or with the other Underwriters and the obligations of you and each of the other Underwriters are several and not joint. Each Underwriter elects to be excluded from the application of Subchapter K, Chapter 1, Subtitle A, of the United States Internal Revenue Code of 1986, as amended. Each Underwriter authorizes the Manager, on behalf of such Underwriter, to execute such evidence of such election as may be required by the United States Internal Revenue Service.

12.2. Liability of Manager. The Manager shall be under no liability to you for any act or omission except for obligations expressly assumed by the Manager in the applicable AAU.

SALOMON SMITH BARNEY INC.

In connection with each Offering covered by the Salomon Smith Barney Inc. Master Agreement Among Underwriters dated June 1, 1999, we confirm that except as set forth in a timely reply by us to the Invitation Wire:

(1) Neither we nor any of our directors, officers or partners have a material relationship (as "material" is defined in Regulation C under the 1933 Act) with the Issuer, the Guarantor or any Seller.

(2) (If the offer and sale of the Securities are to be registered under the 1933 Act pursuant to a Registration Statement on Form S-1 of Form F-1:) Neither we nor any "group" (as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")) of which we are a member is the beneficial owner (determined in accordance with Rule 13d-3 under the Exchange Act) of more than 5% of any class of voting securities of the Issuer or the Guarantor, nor do we have any knowledge that more than 5% of any class of voting securities of the Issuer or the Guarantor is held or to be held subject to any voting trust or other similar agreement.

(3) Other than as may be stated in the Salomon Smith Barney Master Agreement Among Underwriters dated June 1, 1999, the applicable AAU, the Intersyndicate Agreement or dealer agreement, if any, the Prospectus, the Registration Statement or the Offering Circular, we do not know and have no reason to believe that there is an intention to over-allot or that the price of any security may be stabilized to facilitate the offering of the Securities.

(4) Except as described in the Prospectus or Offering Circular, as the case may, be and the Invitation Wire, we do not know of any discounts or commissions to be allowed or paid to dealers, including all cash, securities, contracts or other consideration to be received by any dealer in connection with the sale of the securities.

22

(5) We have not prepared any report or memorandum for external use in connection with the Offering. (If there are any exceptions, (i) furnish four (4) copies of each report and memorandum to Salomon Smith Barney Inc., 388 Greenwich Street, New York, N.Y. 10013, Attention: Investment Banking Department/Transaction Structuring Group, (ii) identify each class of person who received such material and the number of copies distributed to each such class, and (iii) indicate when such distribution commenced and ceased.)

We understand that under Rule 2720 (except as provided in Rule 2720(b)(1)(C) thereof) two entities are "affiliates" of each other if one entity controls, is controlled by, or is under common control with, the second entity and that "control" is presumed to exist if one entity (or, in the case of an NASD member, the entity and all "persons associated with" it (as defined in the NASD By-Laws)) beneficially owns 10% or more of the second entity's outstanding voting securities or, if the second entity is a partnership, if the first entity has a partnership interest in 10% or more of the second entity's distributable profits or losses.

In that regard, we specifically confirm that we, our "parent" (as defined in Rule 2720), affiliates and "persons associated with" us (as defined in the NASD By-Laws), in the aggregate do not (i) beneficially own 10% or more of the Issuer's or the Guarantor's "common equity", "preferred equity", or "subordinated debt" (as each such term is defined in Rule 2720), or (ii) in the case of an Issuer or Guarantor which is a partnership, beneficially own a general, limited or special partnership interest in 10% or more

23

(10) (If filing with the NASD is required:) There is no association or affiliation between us and (i) any officer or director of the Issuer, the Guarantor or any Issuer Related Party, or (ii) any securityholder of five percent or more (or, in the case of an initial public offering of equity securities, any securityholder) of any class of securities of the Issuer, the Guarantor or an Issuer Related Party; it being understood that for purposes of paragraph (9) above and this paragraph (10), the term "Issuer Related Party" includes any Seller, any affiliate of the Issuer the Guarantor or a Seller and the officers or general partners, directors, employees and securityholders thereof. (If there are any exceptions, state the identity of the person with whom the association or affiliation exists and, if relevant, the number of equity securities or the face value of debt securities owned by such person, the date such securities were acquired and the price paid for such securities).

(11) (If the Securities are not issued by a real estate investment trust:) No portion of the net offering proceeds from the sale of the Securities will be paid to us or any of our affiliates or "persons associated with" us (as defined in the NASD By-Laws) or members of the immediate family of any such person.

(12) (If the Securities are debt securities and their offer and sale is to be registered under the 1933 Act:) We are not an affiliate (as defined in Rule 0-2 under the Trust Indenture Act of 1939) of the Trustee for the Securities or of its parent, if any. Neither the Trustee nor its parent, if any, nor any of their directors or executive officers is a "director, officer, partner, employee, appointee or

24

representative" of ours (as those terms are defined in the Trust Indenture Act of 1939 or in the relevant instructions to Form T-1). We and our directors, partners, and executive officers, taken as a group, did not on the date specified in the Invitation Wire, and do not, own beneficially 1% or more of the shares of any class of voting securities of the Trustee or of its parent, if any. If we are a corporation, we do not have outstanding and have not assumed or guaranteed any securities issued otherwise than in our present corporate name.

(13) (If the Issuer is a public utility:) We are not a "holding company" or a "subsidiary company" or an "affiliate" of a "holding company" or of a "public-utility company", each as defined in the Public Utility Holding Company Act of 1935.

(14) If we are, or we are affiliated with, a U.S. or non-U.S. bank, we hereby represent that our participation in the offering of the Securities on the terms contemplated in the applicable AAU and the proposed Underwriting Agreement does not contravene any U.S. or state banking law restricting the exercise of securities powers in the United States.

Capitalized terms used but not defined herein shall have the respective meanings given to them in the applicable AAU.

PIMCO High Income Fund
c/o PIMCO Advisors Fund Management LLC
1345 Avenue of the Americas
New York, New York 10105

Ladies and Gentlemen:

We have acted as counsel to PIMCO High Income Fund (the "Fund") in connection with the Registration Statement of the Fund on Form N-2 under the Securities Act of 1933 (File No. 333-104915) and the Investment Company Act of 1940 (File No. 811-21311) (the "Registration Statement"), each as amended (the "Acts"), relating to the proposed sale of an aggregate of 7,200 Auction Rate Cumulative Preferred Shares, Series M, 7,200 Auction Rate Cumulative Preferred Shares, Series T, 7,200 Auction Rate Cumulative Preferred Shares, Series W, 7,200 Auction Rate Cumulative Preferred Shares, Series TH, and 7,200 Auction Rate Cumulative Preferred Shares, Series F (together, the "Preferred Shares"). The Preferred Shares are to be sold pursuant to an Underwriting Agreement substantially in the form filed as an exhibit to the Registration Statement (the "Underwriting Agreement") among the Fund, PIMCO Advisors Fund Management LLC, Citigroup Global Markets Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated and UBS Securities LLC.

We have examined the Fund's Agreement and Declaration of Trust on file in the office of the Secretary of State of The Commonwealth of Massachusetts, as amended (the "Declaration of Trust"), and the Fund's Second Amended and Restated Bylaws, and are familiar with the actions taken by the Fund in connection with the issuance and sale of the Preferred Shares. We have also examined such other documents and records as we have deemed necessary for the purposes of this opinion.

Based upon the foregoing, we are of the opinion that:

1. The Fund is a duly organized and validly existing unincorporated voluntary association with transferable shares under and by virtue of the laws of The Commonwealth of Massachusetts.

2. The Preferred Shares have been duly authorized and, assuming the due execution and delivery of the Underwriting Agreement by an authorized officer of the Fund, when issued and paid for in accordance with the Underwriting Agreement, will be


PIMCO High Income -2- June 23, 2003

validly issued, fully paid and, except as described in the following paragraph, nonassessable by the Fund.

The Fund is an entity of the type commonly known as a "Massachusetts business trust." Under Massachusetts law, shareholders could, under certain circumstances, be held personally liable for the obligations of the Fund. However, the Declaration of Trust disclaims shareholder liability for acts or obligations of the Fund and requires that a notice of such disclaimer be given in each note, bond, contract, instrument, certificate or undertaking entered into or executed by the Fund or its Trustees. The Declaration of Trust provides for indemnification out of the property of the Fund for all loss and expense of any shareholder of the Fund held personally liable solely by reason of his being or having been a shareholder. Thus, the risk of a shareholder's incurring financial loss on account of being a shareholder is limited to circumstances in which the Fund itself would be unable to meet its obligations.

We understand that this opinion is to be used in connection with the registration of the Preferred Shares for offering and sale pursuant to the Securities Act of 1933, as amended. We consent to the filing of this opinion with and as part of the Registration Statement and to the references to our firm in the related prospectus under the captions "Tax matters" and "Legal matters" in the Prospectus contained in the Registration Statement.

Very truly yours,

/s/ Ropes & Gray LLP
