information in the funds' Prospectus dated June 1, 2000. The caption headings
used in this Supplement correspond with the caption headings used in the
Prospectus.

You may purchase class I shares only if you are an eligible institutional
investor, as described under the caption "Description of Share Classes" below.

1. EXPENSE SUMMARY

   EXPENSE TABLE. The "Expense Table" describes the fees and expenses that
   you may pay when you buy, redeem and hold shares of the fund. The table is
   supplemented as follows:

                                                                        CLASS I

      Other Expenses .........................    1.41%            2.92%

        Net Expenses(2) ......................    1.25%            1.25%

- -----------
(1) MFS has contractually agreed, subject to reimbursement, to bear each funds'
    expenses such that "Other Expenses" (after taking into account the expense
    offset arrangement described below), do not exceed 0.25%. These contractual
    arrangements will continue until at least June 1, 2001, unless changed with
    the consent of the board of trustees which oversees the fund.

(2) Each fund has an expense offset arrangement which reduces the fund's
    custodian fee based upon the amount of cash maintained by the fund with its
    custodian and dividend disbursing agent, and may enter into other such
    arrangements and directed brokerage arrangements (which would also have the
    effect of reducing the fund's expenses). Any such fee reductions are not
    reflected in the table. Had such fee reductions been taken into account,
    "Net Expenses" would be lower.

EXAMPLE OF EXPENSES. These expenses are intended to help you compare the cost of
investing in a fund with the cost of investing in other mutual funds. The
"Example of Expenses" table is supplemented as follows:

The examples assume that:

    o You invest $10,000 in the fund for the time periods indicated and you
      redeem your shares at the end of the time periods;

    o Your investment has a 5% return each year and dividends and other
      distributions are reinvested; and

    o The fund's operating expenses remain the same, except that the fund's
      total operating expenses are assumed to be the fund's "Net Expenses" for
      the first year, and the fund's "Total Annual Fund Operating Expenses" for
      subsequent years (see table above.

Although your actual costs may be higher or lower, under these assumptions your
costs would be:

                                           YEAR 1      YEAR 3
                                           ------      ------
      MFS JAPAN EQUITY FUND
      Class I Shares                        $127        $640


                                           YEAR 1      YEAR 3
                                           ------      ------
      MFS GLOBAL TELECOMMUNICATIONS FUND
      Class I Shares                        $127        $950

2. DESCRIPTION OF SHARE CLASSES

The "Description of Share Classes" is supplemented as follows:

If you are an eligible institutional investor (as described below), you may
purchase class I shares at net asset value without an initial sales charge or
CDSC upon redemption. Class I shares do not have annual distribution and service
fees, and do not convert to any other class of shares of a fund.

The following eligible institutional investors may purchase class I shares:

    o certain retirement plans established for the benefit of employees of MFS
      and employees of MFS' affiliates; and

    o any fund distributed by MFS, if the fund seeks to achieve its investment
      objective by investing primarily in shares of a fund and other MFS funds.

In no event will the fund, MFS, MFD or any of their affiliates pay any sales
commissions or compensation to any third party in connection with the sale of
class I shares. The payment of any such sales commission or compensation would,
under the funds' policies, disqualify the purchaser as an eligible investor in
class I shares.

3. HOW TO PURCHASE, EXCHANGE AND REDEEM SHARES

The discussion of "How to Purchase, Exchange and Redeem Shares" is supplemented
as follows:

You may purchase, redeem and exchange class I shares only through your MFD
representative or by contacting MFSC (see the back cover of the Prospectus for
address and phone number). You may exchange your class I shares for class I
shares of another MFS fund (if you are eligible to purchase them) and for shares
of the MFS Money Market Fund at net asset value.

I RISK RETURN SUMMARY
- ---------------------

1:  MFS JAPAN EQUITY FUND

o   INVESTMENT OBJECTIVE

    The fund's investment objective is capital appreciation. The fund's
    objective may be changed without shareholder approval.

    PRINCIPAL INVESTMENT POLICIES

    The fund invests, under normal market conditions, at least 65% of its
    total assets in common stocks and related securities, such as preferred
    stock, convertible securities and depositary receipts, of companies whose
    principal activities are located in Japan.

      A company's principal activities are determined to be located in Japan
    if the company (a) is organized under the laws of, and maintains a
    principal office in Japan, (b) has its principal securities trading market
    in Japan, (c) derives 50% of its total revenues from goods or services
    performed in Japan, or (d) has 50% or more of its assets in Japan.

      The fund focuses on Japanese companies of any size that its investment
    adviser, Massachusetts Financial Services Company (MFS or the adviser),
    believes have above average growth potential. The fund currently intends
    to invest at least 80% of its assets in Japanese securities but may also
    invest in securities of non-Japanese issuers. The fund's investments may
    include securities traded in the over-the-counter markets.

      In selecting securities for the fund, MFS looks particularly for
    companies which demonstrate:

    o a strong franchise, strong cash flows and a recurring revenue stream;

    o a solid industry position, where there is

        > potential for high profit margins and

        > substantial barriers to new entry in the industry;

    o a strong management team with a clearly defined strategy; and

    o a catalyst that may accelerate growth.

      MFS uses a bottom-up, as opposed to a top-down, investment style in
    managing the equity-oriented funds (such as the fund) it advises. This
    means that securities are selected based upon fundamental analysis (such
    as an analysis of earnings, cash-flows, competitive position and
    management's abilities) performed by the fund's portfolio manager and MFS'
    large group of equity research analysts.

      The fund is a non-diversified mutual fund. This means that the fund may
    invest a relatively high percentage of its assets in a small number of
    issuers.

o   PRINCIPAL RISKS

    The principal risks of investing in the fund and the circumstances
    reasonably likely to cause the value of your investment in the fund to
    decline are described below. The share price of the fund generally changes
    daily based on market conditions and other factors. Please note that there
    are many circumstances which could cause the value of your investment in
    the fund to decline, and which could prevent the fund from achieving its
    objective, that are not described here.

      The principal risks of investing in the fund are:

    o Japan Risk: Because the fund will invest a substantial amount of its
      assets in issuers located in Japan, the primary factor affecting the
      fund's performance will be the performance of the Japanese stock market.
      The Japanese stock market's performance (and thus, the fund's performance)
      will be closely tied to economic and political conditions in Japan. In
      recent years, Japan has experienced weak economic growth and high
      unemployment. The Japanese yen has experienced recent periods of
      volatility, and for the past several years, Japan's banking industry has
      been weakened by a significant amount of problem loans. Japan's political
      regime has entered a period of change, and political uncertainty may add
      to the risks of investing in Japan. Although MFS believes that the
      Japanese market has a favorable investment climate, these political,
      regulatory and economic factors may affect the fund's investments in
      issuers in Japan.

    o Geographic Concentration Risk: The fund invests a substantial amount of
      its assets in issuers located in Japan and may also invest in a limited
      number of other Asian countries. Because the fund concentrates its
      investments in this manner, it assumes the risk that economic, political
      and social conditions in those countries will have a significant impact on
      its investment performance. The fund's concentration of assets in a single
      country or region could hurt the fund's performance or may cause the fund
      to be more volatile than a more geographically diversified equity fund.

    o Market Risk: This is the risk that the price of a security held by the
      fund will fall due to changing economic, political or market conditions or
      disappointing earnings results.

    o Company Risk: Prices of securities react to the economic condition of the
      company that issued the security. The fund's equity investments in an
      issuer may rise and fall based on the issuer's actual and anticipated
      earnings, changes in management and the potential for takeovers and
      acquisitions.

    o Non-Diversified Status Risk: Because the fund may invest a higher
      percentage of its assets in a small number of issuers, the fund is more
      susceptible to any single economic, political or regulatory event
      affecting those issuers than is a diversified fund.

    o Foreign Securities Risk: Investments in foreign securities involve risks
      relating to political, social and economic developments abroad, as well as
      risks resulting from the differences between the regulations to which U.S.
      and foreign issuers and markets are subject:

        > These risks may include the seizure by the government of company
          assets, excessive taxation, withholding taxes on dividends and
          interest, limitations on the use or transfer of portfolio assets, and
          political or social instability.

        > Enforcing legal rights may be difficult, costly and slow in foreign
          countries, and there may be special problems enforcing claims against
          foreign governments.

        > Foreign companies may not be subject to accounting standards or
          governmental supervision comparable to U.S. companies, and there may
          be less public information about their operations.

        > Foreign markets may be less liquid and more volatile than U.S.
          markets.

        > Foreign securities often trade in currencies other than the U.S.
          dollar, and the fund may directly hold foreign currencies and purchase
          and sell foreign currencies through forward exchange contracts.
          Changes in currency exchange rates will affect the fund's net asset
          value, the value of dividends and interest earned, and gains and
          losses realized on the sale of securities. An increase in the strength
          of the U.S. dollar relative to these other currencies may cause the
          value of the fund to decline. Certain foreign currencies may be
          particularly volatile, and foreign governments may intervene in the
          currency markets, causing a decline in value or liquidity in the
          fund's foreign currency holdings. By entering into forward foreign
          currency exchange contracts, the fund may be required to forego the
          benefits of advantageous changes in exchange rates, and, in the case
          of forward contracts entered into for the purpose of increasing
          return, the fund may sustain losses which will reduce its gross
          income. Forward foreign currency exchange contracts involve the risk
          that the party with which the fund enters the contract may fail to
          perform its obligations to the fund.

    o Growth Companies Risk: This is the risk that the prices of growth company
      securities held by the fund will fall to a greater extent than the overall
      Japanese equity markets (e.g., as represented by the MSCI Japan Index) due
      to changing economic, political or market conditions or disappointing
      growth company earnings results.

    o Effect of IPOs: The fund may participate in the initial public offering
      ("IPO") market, and a significant portion of the fund's returns may be
      attributable to its investment in IPO's which may have a magnified
      investment performance impact during the periods when the fund has a small
      asset base. Like any past performance, there is no assurance that, as the
      fund's assets grow, it will continue to experience substantially similar
      performance by investment in IPOs.

    o Emerging Markets Risk: Emerging markets are generally defined as countries
      in the initial stages of their industrialization cycles with low per
      capita income. Investments in emerging market securities involve all of
      the risks of investments in foreign securities, and also have additional
      risks:

        > All of the risks of investing in foreign securities are heightened by
          investing in emerging markets countries.

        > The markets of emerging markets countries have been more volatile than
          the markets of developed countries with more mature economies. These
          markets often have provided higher rates of return, and significantly
          greater risks, to investors.

    o Over-the-Counter Risk: Over-the-counter (OTC) transactions involve risks
      in addition to those associated with transactions in securities traded on
      exchanges. OTC-listed companies may have limited product lines, markets or
      financial resources. Many OTC stocks trade less frequently and in smaller
      volume than exchange-listed stocks. The values of these stocks may be more
      volatile than exchange-listed stocks, and the fund may experience
      difficulty in purchasing or selling these securities at a fair price.

    o As with any mutual fund, you could lose money on your investment in the
      fund.

    An investment in the fund is not a bank deposit and is not insured or
    guaranteed by the Federal Deposit Insurance Corporation or any other
    government agency.

o   BAR CHART AND PERFORMANCE TABLE

    The bar chart and performance table are not included because the fund has
    not had a full calendar year of investment operations.

2:  MFS GLOBAL TELECOMMUNICATIONS FUND

o   INVESTMENT OBJECTIVE

    The fund's investment objective is to achieve long-term growth of capital
    consistent with the preservation of capital. The fund's objective may be
    changed without shareholder approval.

o   PRINCIPAL INVESTMENT POLICIES

    The fund invests, under normal market conditions, at least 65% of its
    total assets in common stocks and related securities, such as preferred
    stock, convertible securities and depositary receipts, of
    telecommunications companies from at least three countries, including the
    U.S. Telecommunications companies are broadly defined to include companies
    involved in the development, manufacturing, sale or servicing of
    telecommunications equipment or services. For example, telecommunications
    companies may include:

    o issuers in the telephone, wireless communications (including cellular
      telephone, microwave and satellite communications, paging and other
      emerging wireless technologies), broadcasting, cable, computer, electronic
      components, and networking industries;

    o issuers involved in the creation and distribution of content including
      media, entertainment, communications, software, publishing, information
      systems and data generation companies; and

    o issuers in other telecommunications related industries including companies
      involved in the support and development of the telecommunications
      infrastructure.

      The fund may also invest in debt securities, including lower rated
    securities (i.e. "junk bonds"), and short-term debt securities of
    governments, supranational agencies and other corporations. The fund's
    investments are not subject to any geographical limitation and may include
    securities of issuers in emerging market countries. The fund's securities
    may be traded in the over-the-counter markets.

      The fund focuses on companies of any size that the fund's investment
    adviser, MFS, believes have above average long-term growth potential or
    are undervalued in the market relative to their long term potential
    (securities with low price-to-book, price-to-sales and/or price-to-
    earnings ratios). MFS looks particularly for companies which demonstrate:

    o above average earnings growth over a sustained period of time;

    o a strong franchise, strong cash flows and a recurring revenue stream;

    o a solid industry position, where there is:

        > potential for high profit margins; and

        > substantial barriers to new entry in the industry;

    o a strong management team with a clearly defined strategy; and

    o a catalyst that may accelerate growth.

      MFS uses a bottom-up, as opposed to a top-down, investment style in
    managing the equity-oriented funds (such as the fund) it advises. This
    means that securities are selected based upon fundamental analysis (such
    as an analysis of earnings, cash-flows, competitive position and
    management's abilities) performed by the fund's portfolio manager and MFS'
    large group of equity research analysts.

      The fund is a non-diversified mutual fund. This means that the fund may
    invest a relatively high percentage of its assets in a small number of
    issuers. The fund may also invest a substantial amount of its assets (i.e.,
    more than 25% of its assets) in issuers located in a single country or a
    limited number of countries.

o   PRINCIPAL RISKS

    The principal risks of investing in the fund and the circumstances
    reasonably likely to cause the value of your investment in the fund to
    decline are described below. The share price of the fund generally changes
    daily based on market conditions and other factors. Please note that there
    are many circumstances which could cause the value of your investment in
    the fund to decline, and which could prevent the fund from achieving its
    objective, that are not described here.

      The principal risks of investing in the fund are:

    o Telecommunications Industry Risk: The value of securities of
      telecommunications companies is particularly vulnerable to rapidly
      changing technology, relatively high risks of obsolescence caused by
      technological advances, and intense competition. For these and other
      reasons, securities of telecommunications companies may be more volatile
      than the overall market. The telecommunications industry is subject to
      certain pro- competitive governmental policies and government regulation
      of rates of return and services that may be offered, and changes in these
      regulations may adversely affect the value of the telecommunications
      company securities held by the fund.

    o Sector Concentration Risk: Because the fund will invest a substantial
      amount of its assets in issuers located in a group of related industries
      (market sector), it assumes the risk that financial, regulatory, business,
      economic and political conditions affecting this market sector will have a
      significant impact on its investment performance. The fund's investment
      performance may also be more volatile because it concentrates its
      investments in a single sector.

    o Market Risk: This is the risk that the price of a security held by the
      fund will fall due to changing economic, political or market conditions or
      disappointing earnings results.

    o Company Risk: Prices of securities react to the economic condition of the
      company that issued the security. The fund's equity investments in an
      issuer may rise and fall based on the issuer's actual and anticipated
      earnings, changes in management and the potential for takeovers and
      acquisitions.

    o Non-Diversified Status Risk: Because the fund may invest a higher
      percentage of its assets in a small number of issuers, the fund is more
      susceptible to any single economic, political or regulatory event
      affecting those issuers than is a diversified fund.

    o Foreign Markets Risk: Investing in foreign securities involves risks
      relating to political, social and economic developments abroad, as well as
      risks resulting from the differences between the regulations to which U.S.
      and foreign issuers and markets are subject:

        > These risks may include the seizure by the government of company
          assets, excessive taxation, withholding taxes on dividends and
          interest, limitations on the use or transfer of portfolio assets, and
          political or social instability.

        > Enforcing legal rights may be difficult, costly and slow in foreign
          countries, and there may be special problems enforcing claims against
          foreign governments.

        > Foreign companies may not be subject to accounting standards or
          governmental supervision comparable to U.S. companies, and there may
          be less public information about their operations.

        > Foreign markets may be less liquid and more volatile than U.S.
          markets.

        > Foreign securities often trade in currencies other than the U.S.
          dollar, and the fund may directly hold foreign currencies and purchase
          and sell foreign currencies through forward exchange contracts.
          Changes in currency exchange rates will affect the fund's net asset
          value, the value of dividends and interest earned, and gains and
          losses realized on the sale of securities. An increase in the strength
          of the U.S. dollar relative to these other currencies may cause the
          value of the fund to decline. Certain foreign currencies may be
          particularly volatile, and foreign governments may intervene in the
          currency markets, causing a decline in value or liquidity in the
          fund's foreign currency holdings. By entering into forward foreign
          currency exchange contracts, the fund may be required to forego the
          benefits of advantageous changes in exchange rates and, in the case of
          forward contracts entered into for the purpose of increasing return,
          the fund may sustain losses which will reduce its gross income.
          Forward foreign currency exchange contracts involve the risk that the
          party with which the fund enters the contract may fail to perform its
          obligations to the fund.

    o Emerging Markets Risk: Emerging markets are generally defined as countries
      in the initial stages of their industrialization cycles with low per
      capita income. Investments in emerging markets securities involve all of
      the risks of investments in foreign securities, and also have additional
      risks:

        > All of the risks of investing in foreign securities are heightened by
          investing in emerging markets countries.

        > The markets of emerging markets countries have been more volatile than
          the markets of developed countries with more mature economies. These
          markets often have provided significantly higher or lower rates of
          return than developed markets, and significantly greater risks, to
          investors.

    o Geographic Concentration Risk: Because the fund may invest a substantial
      amount of its assets in issuers located in a single country or a limited
      number of countries, economic, political and social conditions in these
      countries will have a significant impact on its investment performance.

    o Growth Companies Risk: Prices of growth company securities held by the
      fund may fall to a greater extent than the overall equity markets (e.g.,
      as represented by the Standard and Poor's Composite 500 Index) due to
      changing economic, political or market conditions or disappointing growth
      company earnings results.

    o Undervalued Securities Risk: The fund may invest in securities that are
      undervalued based on its belief that the market value of these securities
      will rise due to anticipated events and investor perceptions. If these
      events do not occur or are delayed, or if investor perceptions about the
      securities do not improve, the market price of these securities may not
      rise as expected or may fall.

    o Effect of IPOs: The fund may participate in the initial public offering
      ("IPO") market, and a significant portion of the fund's returns may be
      attributable to its investment in IPO's which may have a magnified
      investment performance impact during the periods when the fund has a small
      asset base. Like any past performance, there is no assurance that, as the
      fund's assets grow, it will continue to experience substantially similar
      performance by investment in IPOs.

    o Over-the-Counter Risk: Over-the-counter (OTC) transactions involve risks
      in addition to those associated with transactions in securities traded on
      exchanges. OTC-listed companies may have limited product lines, markets or
      financial resources. Many OTC stocks and fixed income securities trade
      less frequently and in smaller volume than exchange-listed securities. The
      values of OTC stocks may be more volatile than exchange-listed stocks, and
      the fund may experience difficulty in purchasing or selling these
      securities at a fair price. OTC fixed income securities are subject to
      liquidity risk. This means that they may be harder to purchase or sell at
      a fair price. The inability to purchase or sell these fixed income
      securities at a fair price could have a negative impact on the fund's
      performance.

    o Fixed Income Securities Risk:

        > Interest Rate Risk: When interest rates rise, the prices of fixed
          income securities in the fund's portfolio will generally fall.
          Conversely, when interest rates fall, the prices of fixed income
          securities in the fund's portfolio will generally rise.

        > Maturity Risk: Interest rate risk will generally affect the price of a
          fixed income security more if the security has a longer maturity.
          Fixed income securities with longer maturities will therefore be more
          volatile than other fixed income securities with shorter maturities.
          Conversely, fixed income securities with shorter maturities will be
          less volatile but generally provide lower returns than fixed income
          securities with longer maturities. The average maturity of the fund's
          fixed income investments will affect the volatility of the fund's
          share price.

        > Credit Risk: Credit risk is the risk that the issuer of a fixed income
          security will not be able to pay principal and interest when due.
          Rating agencies assign credit ratings to certain fixed income
          securities to indicate their credit risk. The price of a fixed income
          security will generally fall if the issuer defaults on its obligation
          to pay principal or interest, the rating agencies downgrade the
          issuer's credit rating or other news affects the market's perception
          of the issuer's credit risk.

        > Liquidity Risk: The fixed income securities purchased by the fund may
          be traded in the over-the-counter market rather than on an organized
          exchange and are subject to liquidity risk. This means that they may
          be harder to purchase or sell at a fair price. The inability to
          purchase or sell these fixed income securities at a fair price could
          have a negative impact on the fund's performance.

    o Lower Rated Bonds Risk:

        > Higher Credit Risk: Junk bonds are subject to a substantially higher
          degree of credit risk than higher rated bonds. During recessions, a
          high percentage of issuers of junk bonds may default on payments of
          principal and interest. The price of a junk bond may therefore
          fluctuate drastically due to bad news about the issuer or the economy
          in general.

        > Higher Liquidity Risk: During recessions and periods of broad market
          declines, junk bonds could become less liquid, meaning that they will
          be harder to value or sell at a fair price.

    o As with any mutual fund, you could lose money on your investment in the
      fund.

      An investment in the fund is not a bank deposit and is not insured or
    guaranteed by the Federal Deposit Insurance Corporation or any other
    government agency.

    The bar chart and performance table are not included because the fund has
    not had a full calendar year of investment operations.

        Net Expenses(4) ..........................    1.25%      2.25%     2.25%

    ------
    (1) An initial sales charge will not be deducted from your purchase if you
        buy $1 million or more of class A shares, or if you are investing
        through a retirement plan and your class A purchase meets certain
        requirements. However, in this case, a contingent deferred sales
        charge (referred to as a CDSC) of 1% may be deducted from your
        redemption proceeds if you redeem your investment within 12 months.
    (2) The fund adopted a distribution plan under Rule 12b-1 that permits it
        to pay marketing and other fees to support the sale and distribution
        of class A, B and C shares and the services provided to you by your
        financial adviser (referred to as distribution and service fees).
    (3) MFS has contractually agreed, subject to reimbursement, to bear the
        fund's expenses such that "Other Expenses" (after taking into account
        the expense offset arrangement described below), do not exceed 0.25%.
        In addition, the fund's distributor, MFS Fund Distributors, Inc. has
        contractually agreed to waive the fund's class A distribution and
        service fees. These contractual arrangements will continue until at
        least June 1, 2001, unless changed with the consent of the board of
        trustees which oversees the fund.
    (4) The fund has an expense offset arrangement which reduces the fund's
        custodian fee based upon the amount of cash maintained by the fund
        with its custodian and dividend disbursing agent. The fund may enter
        into other similar arrangements and directed brokerage arrangements,
        which would also have the effect of reducing the fund's expenses. Any
        such fee reductions are not reflected in the table. Had these fee
        reductions been taken into account, "Net Expenses" would be lower.

o   EXAMPLE OF EXPENSES

    These examples are intended to help you compare the cost of investing in
    the fund with the cost of investing in other mutual funds.

    The examples assume that:

    o You invest $10,000 in the fund for the time periods indicated and you
      redeem your shares at the end of the time periods;

    o Your investment has a 5% return each year and dividends and other
      distributions are reinvested; and

    o The fund's operating expenses remain the same, except that the fund's
      total operating expenses are assumed to be the fund's "Net Expenses" for
      the first year, and the fund's "Total Annual Fund Operating Expenses" for
      subsequent years (see the table above).

    Although your actual costs may be higher or lower, under these assumptions
    your costs would be:

    SHARE CLASS                                                YEAR 1    YEAR 3

    Class A shares                                              $695     $1,247
    Class B shares(1)
      Assuming redemption at end of period                      $628     $1,240
      Assuming no redemption                                    $228     $  940
    Class C shares
      Assuming redemption at end of period                      $328     $  940
      Assuming no redemption                                    $228     $  940

    (1) Class B shares convert to class A shares approximately eight years
        after purchase; therefore, years nine and ten reflect class A expenses.

III CERTAIN INVESTMENT STRATEGIES AND RISKS
- -------------------------------------------

o   FURTHER INFORMATION ON INVESTMENT STRATEGIES AND RISKS

    Each fund may invest in various types of securities and engage in various
    investment techniques and practices which are not the principal focus of
    the fund and therefore are not described in this Prospectus. The types of
    securities and investment techniques and practices in which each fund may
    engage, including the principal investment techniques and practices
    described above, are identified in Appendix A to this Prospectus, and are
    discussed, together with their risks, in the fund's Statement of
    Additional Information (referred to as the SAI), which you may obtain by
    contacting MFS Service Center, Inc. (see back cover for address and phone
    number).

o   TEMPORARY DEFENSIVE POLICIES

    In addition, each fund may depart from its principal investment strategies
    by temporarily investing for defensive purposes when adverse market,
    economic or political conditions exist. While a fund invests defensively,
    it may not be able to pursue its investment objectives. A fund's defensive
    investment position may not be effective in protecting its value.

o   ACTIVE OR FREQUENT TRADING

    The funds may engage in active and frequent trading to achieve their
    principal investment strategies. This may result in the realization and
    distribution to shareholders of higher capital gains as compared to a fund
    with less active trading policies, which would increase your tax
    liability. Frequent trading also increases transaction costs, which could
    detract from the fund's performance.

IV MANAGEMENT OF THE FUNDS
- --------------------------

o   INVESTMENT ADVISER

    Massachusetts Financial Services Company (referred to as MFS or the
    adviser) is the fund's investment adviser. MFS is America's oldest mutual
    fund organization. MFS and its predecessor organizations have a history of
    money management dating from 1924 and the founding of the first mutual
    fund, Massachusetts Investors Trust. Net assets under the management of
    the MFS organization were approximately $      billion as of April 30,
    2000. MFS is located at 500 Boylston Street, Boston, Massachusetts 02116.

      MFS provides investment management and related administrative services
    and facilities to each fund (including portfolio management and trade
    execution). For these services, MFS is entitled to an annual management
    fee as set forth in the Expense Summary.

o   PORTFOLIO MANAGERS

    MFS JAPAN                        The fund is managed by a committee of
      EQUITY FUND --                 various equity research analysts employed
                                     by the adviser under the general
                                     oversight of David A. Antonelli, the

V DESCRIPTION OF SHARE CLASSES
- ------------------------------

    Each fund offers class A, B and C shares through this prospectus. Each
    fund also offers an additional class of shares, class I shares,
    exclusively to certain institutional investors. Class I shares are made
    available through a separate prospectus supplement provided to
    institutional investors eligible to purchase them. Class A and class I
    shares are the only classes presently available for sale.

o   SALES CHARGES

    You may be subject to an initial sales charge when you purchase, or a CDSC
    when you redeem, class A, B or C shares. These sales charges are described
    below. In certain circumstances, these sales charges are waived. These
    circumstances are described in the SAI. Special considerations concerning
    the calculation of the CDSC that apply to each of these classes of shares
    are described below under the heading "Calculation of CDSC."

      If you purchase your fund shares through a financial adviser (such as a
    broker or bank), the adviser may receive commissions or other concessions
    which are paid from various sources, such as from the sales charges and
    distribution and service fees, or from MFS or MFD. These commissions and
    concessions are described in the SAI.

o   CLASS A SHARES

    You may purchase class A shares at net asset value plus an initial sales
    charge (referred to as the offering price), but in some cases you may
    purchase class A shares without an initial sales charge but subject to a
    1% CDSC upon redemption within one year. Class A shares have annual
    distribution and service fees up to a maximum of 0.35% of net assets
    annually.

    PURCHASES SUBJECT TO AN INITIAL SALES CHARGE. The amount of the initial
    sales charge you pay when you buy class A shares differs depending upon
    the amount you invest, as follows:

                                                 SALES CHARGE* AS PERCENTAGE OF:
                                                 -----------------------------
                                                  Offering        Net Amount
    Amount of Purchase                              Price          Invested

    Less than $50,000                               5.75%           6.10%
    $50,000 but less than $100,000                  4.75%           4.99%
    $100,000 but less than $250,000                 4.00            4.17
    $250,000 but less than $500,000                 2.95            3.04
    $500,000 but less than $1,000,000               2.20            2.25
    $1,000,000 or more                             None**          None**

    ------
     * Because of rounding in the calculation of offering price, actual sales
       charges you pay may be more or less than those calculated using these
       percentages.
    ** A 1% CDSC will apply to such purchases, as discussed below.

    PURCHASES SUBJECT TO A CDSC (BUT NOT AN INITIAL SALES CHARGE). You pay no
    initial sales charge when you invest $1 million or more in class A shares.
    However, a CDSC of 1% will be deducted from your redemption proceeds if
    you redeem within 12 months of your purchase.

      In addition, purchases made under the following four categories are not
    subject to an initial sales charge; however, a CDSC of 1% will be deducted
    from redemption proceeds if the redemption is made within 12 months of
    purchase:

    o  Investments in class A shares by certain retirement plans subject to the
       Employee Retirement Income Security Act of 1974, as amended (referred to
       as ERISA), if, prior to July 1, 1996

        > the plan had established an account with MFSC; and

        > the sponsoring organization had demonstrated to the satisfaction of
          MFD that either;

            + the employer had at least 25 employees; or

            + the total purchases by the retirement plan of class A shares of
              the MFS Family of Funds (the MFS Funds) would be in the amount of
              at least $250,000 within a reasonable period of time, as
              determined by MFD in its sole discretion.

    o  Investments in class A shares by certain retirement plans subject to
       ERISA, if

        > the retirement plan and/or sponsoring organization participates in the
          MFS Corporate Plan Services 401(k) Program or any similar
          recordkeeping system made available by MFSC (referred to as the MFS
          participant recordkeeping system);

        > the plan establishes an account with MFSC on or after July 1, 1996;

        > the total purchases by the retirement plan (or by multiple plans
          maintained by the same plan sponsor) of class A shares of the MFS
          Funds will be in the amount of at least $500,000 within a reasonable
          period of time, as determined by MFD in its sole discretion; and

    o  Investments in class A shares by certain retirement plans subject to
       ERISA, if

        > the plan establishes an account with MFSC on or after July 1, 1996;
          and

        > the plan has, at the time of purchase, either alone or in aggregate
          with other plans maintained by the same plan sponsor, a market value
          of $500,000 or more invested in shares of any class or classes of the
          MFS Funds.

          THE RETIREMENT PLANS WILL QUALIFY UNDER THIS CATEGORY ONLY IF THE
          PLANS OR THEIR SPONSORING ORGANIZATION INFORMS MFSC PRIOR TO THE
          PURCHASES THAT THE PLANS HAVE A MARKET VALUE OF $500,000 OR MORE
          INVESTED IN SHARES OF ANY CLASS OR CLASSES OF THE MFS FUNDS; MFSC HAS
          NO OBLIGATION INDEPENDENTLY TO DETERMINE WHETHER SUCH PLANS QUALIFY
          UNDER THIS CATEGORY; AND

    o  Investments in class A shares by certain retirement plans subject to
       ERISA, if

        > the plan established an account with MFSC between July 1, 1997 and
          December 31, 1999;

        > the plan records are maintained on a pooled basis by MFSC; and

        > the sponsoring organization demonstrates to the satisfaction of MFD
          that, at the time of purchase, the employer has at least 200 eligible
          employees and the plan has aggregate assets of at least $2,000,000.

o   CLASS B SHARES

    You may purchase class B shares at net asset value without an initial
    sales charge, but if you redeem your shares within the first six years you
    may be subject to a CDSC (declining from 4.00% during the first year to 0%
    after six years). Class B shares have annual distribution and service fees
    up to a maximum of 1.00% of net assets annually.

      The CDSC is imposed according to the following schedule:

                                                           CONTINGENT DEFERRED
    YEAR OF REDEMPTION AFTER PURCHASE                         SALES CHARGE
    ----------------------------------------------------------------------------

    First                                                          4%
    Second                                                         4%
    Third                                                          3%
    Fourth                                                         3%
    Fifth                                                          2%
    Sixth                                                          1%
    Seventh and following                                          0%

      If you hold class B shares for approximately eight years, they will
    convert to class A shares of the fund. All class B shares you purchased
    through the reinvestment of dividends and distributions will be held in a
    separate sub-account. Each time any class B shares in your account convert
    to class A shares, a proportionate number of the class B shares in the
    sub-account will also convert to class A shares.

o   CLASS C SHARES

    You may purchase class C shares at net asset value without an initial
    sales charge, but if you redeem your shares within the first year you may
    be subject to a CDSC of 1.00%. Class C shares have annual distribution and
    service fees up to a maximum of 1.00% of net assets annually. Class C
    shares do not convert to any other class of shares of the fund.

o   CALCULATION OF CDSC

    As discussed above, certain investments in class A, B and C shares will be
    subject to a CDSC. Two different aging schedules apply to the calculation
    of the CDSC:

    o Purchases of class A shares made on any day during a calendar month will
      age one month on the last day of the month, and each subsequent month.

    o Purchases of class C shares, and purchases of class B shares on or after
      January 1, 1993, made on any day during a calendar month will age one year
      at the close of business on the last day of that month in the following
      calendar year, and each subsequent year.

      No CDSC is assessed on the value of your account represented by
    appreciation or additional shares acquired through the automatic
    reinvestment of dividends or capital gain distributions. Therefore, when
    you redeem your shares, only the value of the shares in excess of these
    amounts (i.e., your direct investment) is subject to a CDSC.

      The CDSC will be applied in a manner that results in the CDSC being
    imposed at the lowest possible rate, which means that the CDSC will be
    applied against the lesser of your direct investment or the total cost of
    your shares. The applicability of a CDSC will not be affected by exchanges
    or transfers of registration, except as described in the SAI.

o   DISTRIBUTION AND SERVICE FEES

    Each fund has adopted a plan under Rule 12b-1 that permits it to pay
    marketing and other fees to support the sale and distribution of class A,
    B and C shares and the services provided to you by your financial adviser.
    These annual distribution and service fees may equal up to 0.35% for class
    A shares (a 0.10% distribution fee and a 0.25% service fee) and 1.00% for
    each of class B and class C shares (a 0.75% distribution fee and a 0.25%
    service fee), and are paid out of the assets of these classes. Over time,
    these fees will increase the cost of your shares and may cost you more
    than paying other types of sales charges. MFD has waived its right to
    receive the class A service fee and the class A distribution fee as
    described under "Expense Summary."

- ----------------------------------------------
VI HOW TO PURCHASE, EXCHANGE AND REDEEM SHARES
- ----------------------------------------------

    You may purchase, exchange and redeem class A, B and C shares of each fund
    in the manner described below. In addition, you may be eligible to
    participate in certain investor services and programs to purchase,
    exchange and redeem these classes of shares, which are described in the
    next section under the caption "Investor Services and Programs."

o   HOW TO PURCHASE SHARES

    INITIAL PURCHASE. You can establish an account by having your financial
    adviser process your purchase. The minimum initial investment is $1,000.
    However, in the following circumstances the minimum initial investment is
    only $50 per account:

    o if you establish an automatic investment plan;

    o if you establish an automatic exchange plan; or

    o if you establish an account under either:

        > tax-deferred retirement programs (other than IRAs) where investments
          are made by means of group remittal statements; or

        > employer sponsored investment programs.

      The minimum initial investment for IRAs is $250 per account. The maximum
    investment in class C shares is $1,000,000 per transaction. Class C shares
    are not available for purchase by any retirement plan qualified under
    Section 401(a) or 403(b) of the Internal Revenue Code if the plan or its
    sponsor subscribes to certain recordkeeping services made available by
    MFSC, such as the MFS Corporate Plan Services 401(k) Plan.

    ADDING TO YOUR ACCOUNT. There are several easy ways you can make
    additional investments of at least $50 to your account:

    o send a check with the returnable portion of your statement;

    o ask your financial adviser to purchase shares on your behalf;

    o wire additional investments through your bank (call MFSC first for
      instructions); or

    o authorize transfers by phone between your bank account and your MFS
      account (the maximum purchase amount for this method is $100,000). You
      must elect this privilege on your account application if you wish to use
      it.

o   HOW TO EXCHANGE SHARES

    You can exchange your shares for shares of the same class of certain other
    MFS funds at net asset value by having your financial adviser process your
    exchange request or by contacting MFSC directly. The minimum exchange
    amount is generally $1,000 ($50 for exchanges made under the automatic
    exchange plan). Shares otherwise subject to a CDSC will not be charged a
    CDSC in an exchange. However, when you redeem the shares acquired through
    the exchange, the shares you redeem may be subject to a CDSC, depending
    upon when you originally purchased the shares you exchanged. For purposes
    of computing the CDSC, the length of time you have owned your shares will
    be measured from the date of original purchase and will not be affected by
    any exchange.

      Sales charges may apply to exchanges made from the MFS money market
    funds. Certain qualified retirement plans may make exchanges between the
    MFS funds and the MFS Fixed Fund, a bank collective investment fund, and
    sales charges may also apply to these exchanges. Call MFSC for information
    concerning these sales charges.

      Exchanges may be subject to certain limitations and are subject to the
    MFS funds' policies concerning excessive trading practices, which are
    policies designed to protect the funds and their shareholders from the
    harmful effect of frequent exchanges. These limitations and policies are
    described below under the captions "Right to Reject or Restrict Purchase
    and Exchange Orders" and "Excessive Trading Practices." You should read
    the prospectus of the MFS fund into which you are exchanging and consider
    the differences in objectives, policies and rules before making any
    exchange.

o   HOW TO REDEEM SHARES

    You may redeem your shares either by having your financial adviser process
    your redemption or by contacting MFSC directly. The fund sends out your
    redemption proceeds within seven days after your request is received in
    good order. "Good order" generally means that the stock power, written
    request for redemption, letter of instruction or certificate must be
    endorsed by the record owner(s) exactly as the shares are registered. In
    addition, you need to have your signature guaranteed and/or submit
    additional documentation to redeem your shares. See "Signature Guarantee/
    Additional Documentation" below, or contact MFSC for details (see back
    cover page for address and phone number).

      Under unusual circumstances such as when the New York Stock Exchange is
    closed, trading on the Exchange is restricted or if there is an emergency,
    the fund may suspend redemptions or postpone payment. If you purchased the
    shares you are redeeming by check, the fund may delay the payment of the
    redemption proceeds until the check has cleared, which may take up to 15
    days from the purchase date.

    REDEEMING DIRECTLY THROUGH MFSC

    o BY TELEPHONE. You can call MFSC to have shares redeemed from your account
      and the proceeds wired or mailed (depending on the amount redeemed)
      directly to a pre- designated bank account. MFSC will request personal or
      other information from you and will generally record the calls. MFSC will
      be responsible for losses that result from unauthorized telephone
      transactions if it does not follow reasonable procedures designed to
      verify your identity. You must elect this privilege on your account
      application if you wish to use it.

    o BY MAIL. To redeem shares by mail, you can send a letter to MFSC with the
      name of your fund, your account number, and the number of shares or dollar
      amount to be sold.

    REDEEMING THROUGH YOUR FINANCIAL ADVISER. You can call your financial
    adviser to process a redemption on your behalf. Your financial adviser
    will be responsible for furnishing all necessary documents to MFSC and may
    charge you for this service.

    SIGNATURE GUARANTEE/ADDITIONAL DOCUMENTATION. In order to protect against
    fraud, each fund requires that your signature be guaranteed in order to
    redeem your shares. Your signature may be guaranteed by an eligible bank,
    broker, dealer, credit union, national securities exchange, registered
    securities association, clearing agency, or savings association. MFSC may
    require additional documentation for certain types of registrations and
    transactions. Signature guarantees and this additional documentation shall
    be accepted in accordance with policies established by MFSC, and MFSC may
    make certain de minimis exceptions to these requirements.

o   OTHER CONSIDERATIONS

    RIGHT TO REJECT OR RESTRICT PURCHASE AND EXCHANGE ORDERS. Purchases and
    exchanges should be made for investment purposes only. The MFS Funds each
    reserve the right to reject or restrict any specific purchase or exchange
    request. Because an exchange request involves both a request to redeem
    shares of one fund and to purchase shares of another fund, the MFS Funds
    consider the underlying redemption and purchase requests conditioned upon
    the acceptance of each of these underlying requests. Therefore, in the
    event that the MFS Funds reject an exchange request, neither the
    redemption nor the purchase side of the exchange will be processed. When a
    fund determines that the level of exchanges on any day may be harmful to
    its remaining shareholders, the fund may delay the payment of exchange
    proceeds for up to seven days to permit cash to be raised through the
    orderly liquidation of its portfolio securities to pay the redemption
    proceeds. In this case, the purchase side of the exchange will be delayed
    until the exchange proceeds are paid by the redeeming fund.

    EXCESSIVE TRADING PRACTICES. The MFS Funds do not permit market-timing or
    other excessive trading practices. Excessive, short-term (market-timing)
    trading practices may disrupt portfolio management strategies and harm
    fund performance. As noted above, the MFS Funds reserve the right to
    reject or restrict any purchase order (including exchanges) from any
    investor. To minimize harm to the MFS Funds and their shareholders, the
    MFS Funds will exercise these rights if an investor has a history of
    excessive trading or if an investor's trading, in the judgment of the MFS
    Funds, has been or may be disruptive to a fund. In making this judgment,
    the MFS Funds may consider trading done in multiple accounts under common
    ownership or control.

    REINSTATEMENT PRIVILEGE. After you have redeemed shares, you have a one-
    time right to reinvest the proceeds within 90 days of the redemption at
    the current net asset value (without an initial sales charge). If the
    redemption involved a CDSC, your account will be credited with the
    appropriate amount of the CDSC paid; however, your new shares will be
    subject to a CDSC which will be determined from the date you originally
    purchased the shares redeemed.

    IN-KIND DISTRIBUTIONS. The MFS funds have reserved the right to pay
    redemption proceeds by a distribution in-kind of portfolio securities
    (rather than cash). In the event that a fund makes an in-kind
    distribution, you could incur the brokerage and transaction charges when
    converting the securities to cash. None of the funds expects to make in-
    kind distributions, and if a fund does, it will pay, during any 90-day
    period, your redemption proceeds in cash up to either $250,000 or 1% of
    the fund's net assets, whichever is less.

    INVOLUNTARY REDEMPTIONS/SMALL ACCOUNTS. Because it is costly to maintain
    small accounts, the MFS funds have generally reserved the right to
    automatically redeem shares and close your account when it contains less
    than $500 due to your redemptions or exchanges. Before making this
    automatic redemption, you will be notified and given 60 days to make
    additional investments to avoid having your shares redeemed.
<PAGE>

- ----------------------------------
VII INVESTOR SERVICES AND PROGRAMS
- ----------------------------------

    As a shareholder of a fund, you have available to you a number of services
    and investment programs. Some of these services and programs may not be
    available to you if your shares are held in the name of your financial
    adviser or if your investment in a fund is made through a retirement plan.

o   DISTRIBUTION OPTIONS

    The following distribution options are generally available to all accounts
    and you may change your distribution option as often as you desire by
    notifying MFSC:

    o Dividend and capital gain distributions reinvested in additional shares
      (this option will be assigned if no other option is specified);

    o Dividend distributions in cash; capital gain distributions reinvested in
      additional shares; or

    o Dividend and capital gain distributions in cash.

      Reinvestments (net of any tax withholding) will be made in additional
    full and fractional shares of the same class of shares at the net asset
    value as of the close of business on the record date. Distributions in
    amounts less than $10 will automatically be reinvested in additional
    shares of the fund. If you have elected to receive distributions in cash,
    and the postal or other delivery service is unable to deliver checks to
    your address of record, or you do not respond to mailings from MFSC with
    regard to uncashed distribution checks, your distribution option will
    automatically be converted to having all distributions reinvested in
    additional shares. Your request to change a distribution option must be
    received by MFSC by the distribution record date for a distribution in
    order to be effective for that distribution. No interest will accrue on
    amounts represented by uncashed distribution or redemption checks.

o   PURCHASE AND REDEMPTION PROGRAMS

    For your convenience, the following purchase and redemption programs are
    made available to you with respect to class A, B and C shares, without
    extra charge:

    AUTOMATIC INVESTMENT PLAN. You can make cash investments of $50 or more
    through your checking account or savings account on any day of the month.
    If you do not specify a date, the investment will automatically occur on
    the first business day of the month.

    AUTOMATIC EXCHANGE PLAN. If you have an account balance of at least $5,000
    in any MFS fund, you may participate in the automatic exchange plan, a
    dollar-cost averaging program. This plan permits you to make automatic
    monthly or quarterly exchanges from your account in an MFS fund for shares
    of the same class of shares of other MFS funds. You may make exchanges of
    at least $50 to up to six different funds under this plan. Exchanges will
    generally be made at net asset value without any sales charges. If you
    exchange shares out of the MFS Money Market Fund or MFS Government Money
    Market Fund, or if you exchange class A shares out of the MFS Cash Reserve
    Fund, into class A shares of any other MFS fund, you will pay the initial
    sales charge if you have not already paid this charge on these shares.

    REINVEST WITHOUT A SALES CHARGE. You can reinvest dividend and capital
    gain distributions into your account without a sales charge to add to your
    investment easily and automatically.

    DISTRIBUTION INVESTMENT PROGRAM. You may purchase shares of any MFS fund
    without paying an initial sales charge or a CDSC upon redemption by
    automatically reinvesting a minimum of $50 of dividend and capital gain
    distributions from the same class of another MFS fund.

    LETTER OF INTENT (LOI). If you intend to invest $50,000 or more in the MFS
    funds (including the MFS Fixed Fund) within 13 months, you may buy class A
    shares of the funds at the reduced sales charge as though the total amount
    were invested in class A shares in one lump sum. If you intend to invest
    $1 million or more under this program, the time period is extended to 36
    months. If the intended purchases are not completed within the time
    period, shares will automatically be redeemed from a special escrow
    account established with a portion of your investment at the time of
    purchase to cover the higher sales charge you would have paid had you not
    purchased your shares through this program.

    RIGHT OF ACCUMULATION. You will qualify for a lower sales charge on your
    purchases of class A shares when your new investment in class A shares,
    together with the current (offering price) value of all your holdings in
    the MFS funds (including the MFS Fixed Fund), reaches a reduced sales
    charge level.

    SYSTEMATIC WITHDRAWAL PLAN. You may elect to automatically receive (or
    designate someone else to receive) regular periodic payments of at least
    $100. Each payment under this systematic withdrawal is funded through the
    redemption of your fund shares. For class B and C shares, you can receive
    up to 10% (15% for certain IRA distributions) of the value of your account
    through these payments in any one year (measured at the time you establish
    this plan). You will incur no CDSC on class B and C shares redeemed under
    this plan. For class A shares, there is no similar percentage limitation;
    however, you may incur the CDSC (if applicable) when class A shares are
    redeemed under this plan.

VIII OTHER INFORMATION
- ----------------------

o   PRICING OF FUND SHARES

    The price of each class of each fund's shares is based on its net asset
    value. The net asset value of each class of shares is determined at the
    close of regular trading each day that the New York Stock Exchange is open
    for trading (generally, 4:00 p.m., Eastern time) (referred to as the
    valuation time). The New York Stock Exchange is closed on most national
    holidays and Good Friday. To determine net asset value, each fund values
    its assets at current market values, or at fair value as determined by the
    Adviser under the direction of the Board of Trustees that oversees the
    fund if current market values are unavailable. Fair value pricing may be
    used by each fund when current market values are unavailable or when an
    event occurs after the close of the exchange on which the fund's portfolio
    securities are principally traded that is likely to have changed the value
    of the securities. The use of fair value pricing by a fund may cause the
    net asset value of its shares to differ significantly from the net asset
    value that would be calculated using current market values.

      You will receive the net asset value next calculated, after the
    deduction of applicable sales charges and any required tax withholding, if
    your order is complete (has all required information) and MFSC receives
    your order by:

    o the valuation time, if placed directly by you (not through a financial
      adviser such as a broker or bank) to MFSC; or

    o MFSC's close of business, if placed through a financial adviser, so long
      as the financial adviser (or its authorized designee) received your order
      by the valuation time.

    Each fund invests in certain securities which are primarily listed on
    foreign exchanges that trade on weekends and other days when the fund does
    not price its shares. Therefore, the value of a fund's shares may change
    on days when you will not be able to purchase or redeem the fund's shares.

- -

    DISTRIBUTIONS

    Each fund intends to pay substantially all of its net income (including
    any realized net capital gains) to shareholders at least annually.

o   TAX CONSIDERATIONS

    The following discussion is very general. You are urged to consult your
    tax adviser regarding the effect that an investment in a fund may have on
    your particular tax situation.

    TAXABILITY OF DISTRIBUTIONS. As long as a fund qualifies for treatment as
    a regulated investment company (which each fund intends to do in its first
    and each subsequent taxable year), it pays no federal income tax on the
    earnings it distributes to shareholders.

    You will normally have to pay federal income taxes, and any state or local
    taxes, on the distributions you receive from a fund, whether you take the
    distributions in cash or reinvest them in additional shares. Distributions
    designated as capital gain dividends are taxable as long-term capital
    gains. Other distributions are generally taxable as ordinary income. Some
    dividends paid in January may be taxable as if they had been paid the
    previous December.

    The Form 1099 that is mailed to you every January details your
    distributions and how they are treated for federal tax purposes.

    Each fund's distributions will reduce that fund's net asset value per
    share. Therefore, if you buy shares shortly before the record date of a
    distribution, you may pay the full price for the shares and then
    effectively receive a portion of the purchase price back as a taxable
    distribution.

    Each fund may be eligible to elect to "pass through" to you foreign income
    taxes that it pays. If a fund makes this election, you will be required to
    include your share of those taxes in gross income as a distribution from
    that fund. You will then be allowed to claim a credit (or a deduction, if
    you itemize deductions) for such amounts on your federal income tax
    return, subject to certain limitations.

    If you are neither a citizen nor a resident of the U.S., each fund will
    withhold U.S. federal income tax at the rate of 30% on taxable dividends
    and other payments that are subject to such withholding. You may be able
    to arrange for a lower withholding rate under an applicable tax treaty if
    you supply the appropriate documentation required by that fund. Each fund
    is also required in certain circumstances to apply backup withholding at
    the rate of 31% on taxable dividends and redemption proceeds paid to any
    shareholder (including a shareholder who is neither a citizen nor a
    resident of the U.S.) who does not furnish to that fund certain
    information and certifications or who is otherwise subject to backup
    withholding. Backup withholding will not, however, be applied to payments
    that have been subject to 30% withholding. Prospective investors in a fund
    should read that fund's Account Application for additional information
    regarding backup withholding of federal income tax.

    TAXABILITY OF TRANSACTIONS. When you redeem, sell or exchange shares, it
    is generally considered a taxable event for you. Depending on the purchase
    price and the sale price of the shares you redeem, sell or exchange, you
    may have a gain or a loss on the transaction. You are responsible for any
    tax liabilities generated by your transaction.

o   UNIQUE NATURE OF FUNDS

    MFS may serve as the investment adviser to other funds which have
    investment goals and principal investment policies and risks similar to
    those of the funds, and which may be managed by a fund's portfolio
    manager(s). While each fund may have many similarities to these other
    funds, its investment performance will differ from their investment
    performance. This is due to a number of differences between the funds,
    including differences in sales charges, expense ratios and cash flows.

o   PROVISION OF ANNUAL AND SEMIANNUAL REPORTS AND PROSPECTUSES

    Each fund produces financial reports every six months and updates its
    prospectus annually. To avoid sending duplicate copies of materials to
    households, only one copy of a fund's annual and semiannual report and
    prospectus will be mailed to shareholders having the same residential
    address on the fund's records. However, any shareholder may contact MFSC
    (see back cover for address and phone number) to request that copies of
    these reports and prospectuses be sent personally to that shareholder.

      INVESTMENT TECHNIQUES, PRACTICES AND RISKS
      The investment objective and principal investment policies of each Fund
      are described in the Prospectus. In pursuing its investment objective and
      principal investment policies, each Fund may engage in a number of

      investment techniques and practices, which may be changed without
      shareholder approval unless indicated otherwise, are identified in
      Appendix A to the Prospectus, and are more fully described, together with
      their associated risks, in Part II of this SAI. The following percentage
      limitations, as a percentage of such Fund's net assets, apply to these
      investment techniques and practices:

                                                               PERCENTAGE

         Securities Lending ......................................... 30%

      INVESTMENT RESTRICTIONS
      Each Fund has adopted the following restrictions which cannot be changed
      without the approval of the holders of a majority of a Fund's shares
      (which, as used in this SAI, means the lesser of (i) more than 50% of the
      outstanding shares of the Trust or a series or class, as applicable, or
      (ii) 67% or more of the outstanding shares of the Trust or a series or
      class, as applicable, present at a meeting at which holders of more than
      50% of the outstanding shares of the Trust or a series or class, as
      applicable, are represented in person or by proxy).

      Except for Investment Restriction (1) and nonfundamental investment policy
      (1), these investment restrictions and policies are adhered to at the time
      of purchase or utilization of assets; a subsequent change in circumstances
      will not be considered to result in a violation of any of the
      restrictions. In the event of a violation of non-fundamental investment
      policy (1), each Fund will reduce the percentage of its assets invested in
      illiquid investments in due course, taking into account the best interests
      of shareholders.

      Terms used below (such as Options and Futures Contracts) are defined in
      Part II of this SAI.

      Each Fund, may not:

        (1) Borrow amounts in excess of 33 1/3% of its total assets including
            amounts borrowed.

        (2) Underwrite securities issued by other persons except insofar as a
            Fund may technically be deemed an underwriter under the Securities
            Act of 1933 in selling a portfolio security.

        (3) Purchase or sell real estate (including limited partnership
            interests but excluding securities secured by real estate or
            interests therein and securities of companies, such as real estate
            investment trusts, which deal in real estate or interests therein),
            interests in oil, gas or mineral leases, commodities or commodity
            contracts (excluding Options, Options on Futures Contracts, Options
            on Stock Indices, Options on Foreign Currency and any other type of
            option, Futures Contracts, any other type of futures contract, and
            Forward Contracts) in the ordinary course of its business. Each Fund
            reserves the freedom of action to hold and to sell real estate,
            mineral leases, commodities or commodity contracts (including
            Options, Options on Futures Contracts, Options on Stock Indices,
            Options on Foreign Currency and any other type of option, Futures
            Contracts, any other type of futures contract, and Forward
            Contracts) acquired as a result of the ownership of securities.

        (4) Issue any senior securities except as permitted by the 1940 Act. For
            purposes of this restriction, collateral arrangements with respect
            to any type of option (including Options on Futures Contracts,
            Options, Options on Stock Indices and Options on Foreign
            Currencies), short sale, Forward Contracts, Futures Contracts, any
            other type of futures contract, and collateral arrangements with
            respect to initial and variation margin, are not deemed to be the
            issuance of a senior security.

        (5) Make loans to other persons; for these purposes, the purchase of
            short-term commercial paper, the purchase of a portion or all of an
            issue of debt securities, the lending of portfolio securities, or
            the investment of a Fund's assets in repurchase agreements, shall
            not be considered the making of a loan.

      In addition, each Fund has the folowing nonfundamental policies which may
      be changed without shareholder approval.

      Each Fund will not:

        (1) invest in illiquid investments, including securities subject to
            legal or contractual restrictions on resale or for which there is no
            readily available market (e.g., trading in the security is
            suspended, or, in the case of unlisted securities, where no market
            exists), if more than 15% of a Fund's net assets (taken at market
            value) would be invested in such securities. Repurchase agreements
            maturing in more than seven days will be deemed to be illiquid for
            purposes of a Fund's limitation on investment in illiquid
            securities. Securities that are not registered under the 1933 Act
            and sold in reliance on Rule 144A thereunder, but are determined to
            be liquid by the Trust's Board of Trustees (or its delegee), will
            not be subject to this 15% limitation.

        (2) Invest for the purpose of exercising control or management.

I     MANAGEMENT OF THE FUND

      TRUSTEES/OFFICERS
      BOARD OVERSIGHT -- The Board of Trustees which oversees the Fund provides
      broad supervision over the affairs of the Fund. The Adviser is responsible
      for the investment management of the Fund's assets, and the officers of
      the Trust are responsible for its operations.

      TRUSTEE RETIREMENT PLAN -- The Trust has a retirement plan for Trustees
      who are non-interested Trustees and Trustees who are not officers of the
      Trust. Under this plan, a Trustee will retire upon reaching a specified
      age (see Part I -- "Appendix B ") ("Retirement Age") and if the Trustee
      has completed at least 5 years of service, he would be entitled to annual
      payments during his lifetime of up to 50% of such Trustee's average annual
      compensation (based on the three years prior to his retirement) depending
      on his length of service. A Trustee may also retire prior to his
      Retirement Age and receive reduced payments if he has completed at least 5
      years of service. Under the plan, a Trustee (or his beneficiaries) will
      also receive benefits for a period of time in the event the Trustee is
      disabled or dies. These benefits will also be based on the Trustee's
      average annual compensation and length of service. The Fund will accrue
      its allocable portion of compensation expenses under the retirement plan
      each year to cover the current year's service and amortize past service
      cost.

      INDEMNIFICATION OF TRUSTEES AND OFFICERS -- The Declaration of Trust of
      the Trust provides that the Trust will indemnify its Trustees and officers
      against liabilities and expenses incurred in connection with litigation in
      which they may be involved because of their offices with the Trust,
      unless, as to liabilities of the Trust or its shareholders, it is
      determined that they engaged in willful misfeasance, bad faith, gross
      negligence or reckless disregard of the duties involved in their offices,
      or with respect to any matter, unless it is adjudicated that they did not
      act in good faith in the reasonable belief that their actions were in the
      best interest of the Trust. In the case of settlement, such
      indemnification will not be provided unless it has been determined
      pursuant to the Declaration of Trust, that they have not engaged in
      willful misfeasance, bad faith, gross negligence or reckless disregard of
      their duties.

      INVESTMENT ADVISER
      The Trust has retained Massachusetts Financial Services Company ("MFS" or
      the "Adviser") as the Fund's investment adviser. MFS and its predecessor
      organizations have a history of money management dating from 1924. MFS is
      a subsidiary of Sun Life of Canada (U.S.) Financial Services Holdings,
      Inc., which in turn is an indirect wholly owned subsidiary of Sun Life of
      Canada (an insurance company).

         MFS has retained, on behalf of certain MFS Funds, sub-investment
      advisers to assist MFS in the management of the Fund's assets. A
      description of these sub-advisers, the services they provide and their
      compensation is provided under the caption "Management of the Fund -- Sub-
      Adviser" in Part I of this SAI for Funds which use sub-advisers.

      INVESTMENT ADVISORY AGREEMENT -- The Adviser manages the Fund pursuant to
      an Investment Advisory Agreement (the "Advisory Agreement"). Under the
      Advisory Agreement, the Adviser provides the Fund with overall investment
      advisory services. Subject to such policies as the Trustees may determine,
      the Adviser makes investment decisions for the Fund. For these services
      and facilities, the Adviser receives an annual management fee, computed
      and paid monthly, as disclosed in the Prospectus under the heading
      "Management of the Fund[s]."

         The Adviser pays the compensation of the Trust's officers and of any
      Trustee who is an officer of the Adviser. The Adviser also furnishes at
      its own expense all necessary administrative services, including office
      space, equipment, clerical personnel, investment advisory facilities, and
      all executive and supervisory personnel necessary for managing the Fund's
      investments and effecting its portfolio transactions.

         The Trust pays the compensation of the Trustees who are not officers of
      MFS and all expenses of the Fund (other than those assumed by MFS)
      including but not limited to: advisory and administrative services;
      governmental fees; interest charges; taxes; membership dues in the
      Investment Company Institute allocable to the Fund; fees and expenses of
      independent auditors, of legal counsel, and of any transfer agent,
      registrar or dividend disbursing agent of the Fund; expenses of
      repurchasing and redeeming shares and servicing shareholder accounts;
      expenses of preparing, printing and mailing prospectuses, periodic
      reports, notices and proxy statements to shareholders and to governmental
      officers and commissions; brokerage and other expenses connected with the
      execution, recording and settlement of portfolio security transactions;
      insurance premiums; fees and expenses of State Street Bank and Trust
      Company, the Fund's custodian, for all services to the Fund, including
      safekeeping of funds and securities and maintaining required books and
      accounts; expenses of calculating the net asset value of shares of the
      Fund; and expenses of shareholder meetings. Expenses relating to the
      issuance, registration and qualification of shares of the Fund and the
      preparation, printing and mailing of prospectuses are borne by the Fund
      except that the Distribution Agreement with MFD requires MFD to pay for
      prospectuses that are to be used for sales purposes. Expenses of the Trust
      which are not attributable to a specific series are allocated between the
      series in a manner believed by management of the Trust to be fair and
      equitable.

         The Advisory Agreement has an initial two year term and continues in
      effect thereafter only if such continuance is specifically approved at
      least annually by the Board of Trustees or by vote of a majority of the
      Fund's shares (as defined in "Investment Restrictions" in Part I of this
      SAI) and, in either case, by a majority of the Trustees who are not
      parties to the Advisory Agreement or interested persons of any such party.
      The Advisory Agreement terminates automatically if it is assigned and may
      be terminated without penalty by vote of a majority of the Fund's shares
      (as defined in "Investment Restrictions" in Part I of this SAI), or by
      either party on not more than 60 days" nor less than 30 days" written
      notice. The Advisory Agreement provides that if MFS ceases to serve as the
      Adviser to the Fund, the Fund will change its name so as to delete the
      initials "MFS" and that MFS may render services to others and may permit
      other fund clients to use the initials "MFS" in their names. The Advisory
      Agreement also provides that neither the Adviser nor its personnel shall
      be liable for any error of judgment or mistake of law or for any loss
      arising out of any investment or for any act or omission in the execution
      and management of the Fund, except for willful misfeasance, bad faith or
      gross negligence in the performance of its or their duties or by reason of
      reckless disregard of its or their obligations and duties under the
      Advisory Agreement.

      ADMINISTRATOR
      MFS provides the Fund with certain financial, legal, compliance,
      shareholder communications and other administrative services pursuant to a
      Master Administrative Services Agreement. Under this Agreement, the Fund
      pays MFS an administrative fee up to 0.015% per annum of the Fund's
      average daily net assets. This fee reimburses MFS for a portion of the
      costs it incurs to provide such services.

      CUSTODIAN
      State Street Bank and Trust Company (the "Custodian") is the custodian of
      the Fund's assets. The Custodian's responsibilities include safekeeping
      and controlling the Fund's cash and securities, handling the receipt and
      delivery of securities, determining income and collecting interest and
      dividends on the Fund's investments, maintaining books of original entry
      for portfolio and fund accounting and other required books and accounts,
      and calculating the daily net asset value of each class of shares of the
      Fund. The Custodian does not determine the investment policies of the Fund
      or decide which securities the Fund will buy or sell. The Fund may,
      however, invest in securities of the Custodian and may deal with the
      Custodian as principal in securities transactions. The Custodian also acts
      as the dividend disbursing agent of the Fund.

      SHAREHOLDER SERVICING AGENT
      MFS Service Center, Inc. ("MFSC"), a wholly owned subsidiary of MFS, is
      the Fund's shareholder servicing agent, pursuant to an Amended and
      Restated Shareholder Servicing Agreement (the "Agency Agreement"). The
      Shareholder Servicing Agent's responsibilities under the Agency Agreement
      include administering and performing transfer agent functions and the
      keeping of records in connection with the issuance, transfer and
      redemption of each class of shares of the Fund. For these services, MFSC
      will receive a fee calculated as a percentage of the average daily net
      assets of the Fund at an effective annual rate of up to 0.1125%. In
      addition, MFSC will be reimbursed by the Fund for certain expenses
      incurred by MFSC on behalf of the Fund. The Custodian has contracted with
      MFSC to perform certain dividend disbursing agent functions for the Fund.

      DISTRIBUTOR
      MFS Fund Distributors, Inc. ("MFD"), a wholly owned subsidiary of MFS,
      serves as distributor for the continuous offering of shares of the Fund
      pursuant to an Amended and Restated Distribution Agreement (the
      "Distribution Agreement"). The Distribution Agreement has an initial two
      year term and continues in effect thereafter only if such continuance is
      specifically approved at least annually by the Board of Trustees or by
      vote of a majority of the Fund's shares (as defined in "Investment
      Restrictions" in Part I of this SAI) and in either case, by a majority of
      the Trustees who are not parties to the Distribution Agreement or
      interested persons of any such party. The Distribution Agreement
      terminates automatically if it is assigned and may be terminated without
      penalty by either party on not more than 60 days' nor less than 30 days'
      notice.

II    PRINCIPAL SHARE CHARACTERISTICS
      Set forth below is a description of Class A, B, C and I shares offered by
      the MFS Family of Funds. Some MFS Funds may not offer each class of shares
      -- see the Prospectus of the Fund to determine which classes of shares the
      Fund offers.

      CLASS A SHARES
      MFD acts as agent in selling Class A shares of the Fund to dealers. The
      public offering price of Class A shares of the Fund is their net asset
      value next computed after the sale plus a sales charge which varies based
      upon the quantity purchased. The public offering price of a Class A share
      of the Fund is calculated by dividing the net asset value of a Class A
      share by the difference (expressed as a decimal) between 100% and the
      sales charge percentage of offering price applicable to the purchase (see
      "How to Purchase, Exchange and Redeem Shares" in the Prospectus). The
      sales charge scale set forth in the Prospectus applies to purchases of
      Class A shares of the Fund alone or in combination with shares of all
      classes of certain other funds in the MFS Family of Funds and other funds
      (as noted under Right of Accumulation) by any person, including members of
      a family unit (e.g., husband, wife and minor children) and bona fide
      trustees, and also applies to purchases made under the Right of
      Accumulation or a Letter of Intent (see "Investment and Withdrawal
      Programs" below). A group might qualify to obtain quantity sales charge
      discounts (see "Investment and Withdrawal Programs" below). Certain
      purchases of Class A shares may be subject to a 1% CDSC instead of an
      initial sales charge, as described in the Fund's Prospectus.

      CLASS B SHARES, CLASS C SHARES AND CLASS I SHARES
      MFD acts as agent in selling Class B, Class C and Class I shares of the
      Fund. The public offering price of Class B, Class C and Class I shares is
      their net asset value next computed after the sale. Class B and C shares
      are generally subject to a CDSC, as described in the Fund's Prospectus.

      WAIVER OF SALES CHARGES
      In certain circumstances, the initial sales charge imposed upon purchases
      of Class A shares and the CDSC imposed upon redemptions of Class A, B and
      C shares are waived. These circumstances are described in Appendix A of
      this Part II. Such sales are made without a sales charge to promote good
      will with employees and others with whom MFS, MFD and/or the Fund have
      business relationships, because the sales effort, if any, involved in
      making such sales is negligible, or in the case of certain CDSC waivers,
      because the circumstances surrounding the redemption of Fund shares were
      not foreseeable or voluntary.

      DEALER COMMISSIONS AND CONCESSIONS
      MFD pays commission and provides concessions to dealers that sell Fund
      shares. These dealer commissions and concessions are described in Appendix
      B of this Part II.

      GENERAL
      Neither MFD nor dealers are permitted to delay placing orders to benefit
      themselves by a price change. On occasion, MFD may obtain brokers loans
      from various banks, including the custodian banks for the MFS Funds, to
      facilitate the settlement of sales of shares of the Fund to dealers. MFD
      may benefit from its temporary holding of funds paid to it by investment
      dealers for the purchase of Fund shares.

III   DISTRIBUTION PLAN
      The Trustees have adopted a Distribution Plan for Class A, Class B and
      Class C shares (the "Distribution Plan") pursuant to Section 12(b) of the
      1940 Act and Rule 12b-1 thereunder (the "Rule") after having concluded
      that there is a reasonable likelihood that the Distribution Plan would
      benefit the Fund and each respective class of shareholders. The provisions
      of the Distribution Plan are severable with respect to each Class of
      shares offered by the Fund. The Distribution Plan is designed to promote
      sales, thereby increasing the net assets of the Fund. Such an increase may
      reduce the expense ratio to the extent the Fund's fixed costs are spread
      over a larger net asset base. Also, an increase in net assets may lessen
      the adverse effect that could result were the Fund required to liquidate
      portfolio securities to meet redemptions. There is, however, no assurance
      that the net assets of the Fund will increase or that the other benefits
      referred to above will be realized.

         In certain circumstances, the fees described below may not be imposed,
      are being waived or do not apply to certain MFS Funds. Current
      distribution and service fees for each Fund are reflected under the
      caption "Expense Summary" in the Prospectus.

      FEATURES COMMON TO EACH CLASS OF SHARES
      There are features of the Distribution Plan that are common to each Class
      of shares, as described below.

      SERVICE FEES -- The Distribution Plan provides that the Fund may pay MFD a
      service fee of up to 0.25% of the average daily net assets attributable to
      the class of shares to which the Distribution Plan relates (i.e., Class A,
      Class B or Class C shares, as appropriate) (the "Designated Class")
      annually in order that MFD may pay expenses on behalf of the Fund relating
      to the servicing of shares of the Designated Class. The service fee is
      used by MFD to compensate dealers which enter into a sales agreement with
      MFD in consideration for all personal services and/or account maintenance
      services rendered by the dealer with respect to shares of the Designated
      Class owned by investors for whom such dealer is the dealer or holder of
      record. MFD may from time to time reduce the amount of the service fees
      paid for shares sold prior to a certain date. Service fees may be reduced
      for a dealer that is the holder or dealer of record for an investor who
      owns shares of the Fund having an aggregate net asset value at or above a
      certain dollar level. Dealers may from time to time be required to meet
      certain criteria in order to receive service fees. MFD or its affiliates
      are entitled to retain all service fees payable under the Distribution
      Plan for which there is no dealer of record or for which qualification
      standards have not been met as partial consideration for personal services
      and/or account maintenance services performed by MFD or its affiliates to
      shareholder accounts.

      DISTRIBUTION FEES -- The Distribution Plan provides that the Fund may pay
      MFD a distribution fee in addition to the service fee described above
      based on the average daily net assets attributable to the Designated Class
      as partial consideration for distribution services performed and expenses
      incurred in the performance of MFD's obligations under its distribution
      agreement with the Fund. MFD pays commissions to dealers as well as
      expenses of printing prospectuses and reports used for sales purposes,
      expenses with respect to the preparation and printing of sales literature
      and other distribution related expenses, including, without limitation,
      the cost necessary to provide distribution-related services, or personnel,
      travel, office expense and equipment. The amount of the distribution fee
      paid by the Fund with respect to each class differs under the Distribution
      Plan, as does the use by MFD of such distribution fees. Such amounts and
      uses are described below in the discussion of the provisions of the
      Distribution Plan relating to each Class of shares. While the amount of
      compensation received by MFD in the form of distribution fees during any
      year may be more or less than the expenses incurred by MFD under its
      distribution agreement with the Fund, the Fund is not liable to MFD for
      any losses MFD may incur in performing services under its distribution
      agreement with the Fund.

      OTHER COMMON FEATURES -- Fees payable under the Distribution Plan are
      charged to, and therefore reduce, income allocated to shares of the
      Designated Class. The provisions of the Distribution Plan relating to
      operating policies as well as initial approval, renewal, amendment and
      termination are substantially identical as they relate to each Class of
      shares covered by the Distribution Plan.

      The Distribution Plan remains in effect from year to year only if its
      continuance is specifically approved at least annually by vote of both the
      Trustees and a majority of the Trustees who are not "interested persons"
      or financially interested parties of such Plan ("Distribution Plan
      Qualified Trustees"). The Distribution Plan also requires that the Fund
      and MFD each shall provide the Trustees, and the Trustees shall review, at
      least quarterly, a written report of the amounts expended (and purposes
      therefor) under such Plan. The Distribution Plan may be terminated at any
      time by vote of a majority of the Distribution Plan Qualified Trustees or
      by vote of the holders of a majority of the respective class of the Fund's
      shares (as defined in "Investment Restrictions" in Part I of this SAI).
      All agreements relating to the Distribution Plan entered into between the
      Fund or MFD and other organizations must be approved by the Board of
      Trustees, including a majority of the Distribution Plan Qualified
      Trustees. Agreements under the Distribution Plan must be in writing, will
      be terminated automatically if assigned, and may be terminated at any time
      without payment of any penalty, by vote of a majority of the Distribution
      Plan Qualified Trustees or by vote of the holders of a majority of the
      respective class of the Fund's shares. The Distribution Plan may not be
      amended to increase materially the amount of permitted distribution
      expenses without the approval of a majority of the respective class of the
      Fund's shares (as defined in "Investment Restrictions" in Part I of this
      SAI) or may not be materially amended in any case without a vote of the
      Trustees and a majority of the Distribution Plan Qualified Trustees. The
      selection and nomination of Distribution Plan Qualified Trustees shall be
      committed to the discretion of the non-interested Trustees then in office.
      No Trustee who is not an "interested person" has any financial interest in
      the Distribution Plan or in any related agreement.

      FEATURES UNIQUE TO EACH CLASS OF SHARES
      There are certain features of the Distribution Plan that are unique to
      each class of shares, as described below.

      CLASS A SHARES -- Class A shares are generally offered pursuant to an
      initial sales charge, a substantial portion of which is paid to or
      retained by the dealer making the sale (the remainder of which is paid to
      MFD). In addition to the initial sales charge, the dealer also generally
      receives the ongoing 0.25% per annum service fee, as discussed above.

         No service fees will be paid: (i) to any dealer who is the holder or
      dealer or record for investors who own Class A shares having an aggregate
      net asset value less than $750,000, or such other amount as may be
      determined from time to time by MFD (MFD, however, may waive this minimum
      amount requirement from time to time); or (ii) to any insurance company
      which has entered into an agreement with the Fund and MFD that permits
      such insurance company to purchase Class A shares from the Fund at their
      net asset value in connection with annuity agreements issued in connection
      with the insurance company's separate accounts.

         The distribution fee paid to MFD under the Distribution Plan is equal,
      on an annual basis, to 0.10% of the Fund's average daily net assets
      attributable to Class A shares (0.25% per annum for certain Funds). As
      noted above, MFD may use the distribution fee to cover distribution-
      related expenses incurred by it under its distribution agreement with the
      Fund, including commissions to dealers and payments to wholesalers
      employed by MFD (e.g., MFD pays commissions to dealers with respect to
      purchases of $1 million or more and purchases by certain retirement plans
      of Class A shares which are sold at net asset value but which are subject
      to a 1% CDSC for one year after purchase). In addition, to the extent that
      the aggregate service and distribution fees paid under the Distribution
      Plan do not exceed 0.35% per annum of the average daily net assets of the
      Fund attributable to Class A shares (0.50% per annum for certain Funds),
      the Fund is permitted to pay such distribution-related expenses or other
      distribution-related expenses.

      CLASS B SHARES -- Class B shares are offered at net asset value without an
      initial sales charge but subject to a CDSC. MFD will advance to dealers
      the first year service fee described above at a rate equal to 0.25% of the
      purchase price of such shares and, as compensation therefor, MFD may
      retain the service fee paid by the Fund with respect to such shares for
      the first year after purchase. Dealers will become eligible to receive the
      ongoing 0.25% per annum service fee with respect to such shares commencing
      in the thirteenth month following purchase.

         Except in the case of the first year service fee, no service fees will
      be paid to any securities dealer who is the holder or dealer of record for
      investors who own Class B shares having an aggregate net asset value of
      less than $750,000 or such other amount as may be determined by MFD from
      time to time. MFD, however, may waive this minimum amount requirement from
      time to time.

         Under the Distribution Plan, the Fund pays MFD a distribution fee
      equal, on an annual basis, to 0.75% of the Fund's average daily net assets
      attributable to Class B shares. As noted above, this distribution fee may
      be used by MFD to cover its distribution-related expenses under its
      distribution agreement with the Fund (including the 3.75% commission it
      pays to dealers upon purchase of Class B shares).

      CLASS C SHARES -- Class C shares are offered at net asset value without an
      initial sales charge but subject to a CDSC of 1.00% upon redemption during
      the first year. MFD will pay a commission to dealers of 1.00% of the
      purchase price of Class C shares purchased through dealers at the time of
      purchase. In compensation for this 1.00% commission paid by MFD to
      dealers, MFD will retain the 1.00% per annum Class C distribution and
      service fees paid by the Fund with respect to such shares for the first
      year after purchase, and dealers will become eligible to receive from MFD
      the ongoing 1.00% per annum distribution and service fees paid by the Fund
      to MFD with respect to such shares commencing in the thirteenth month
      following purchase.

         This ongoing 1.00% fee is comprised of the 0.25% per annum service fee
      paid to MFD under the Distribution Plan (which MFD in turn pays to
      dealers), as discussed above, and a distribution fee paid to MFD (which
      MFD also in turn pays to dealers) under the Distribution Plan, equal, on
      an annual basis, to 0.75% of the Fund's average daily net assets
      attributable to Class C shares.

IV   INVESTMENT TECHNIQUES, PRACTICES AND RISKS
      Set forth in Appendix C of this Part II is a description of investment
      techniques and practices which the MFS Funds may generally use in pursuing
      their investment objectives and principal investment policies, and the
      risks associated with these investment techniques and practices. The Fund
      will engage only in certain of these investment techniques and practices,
      as identified in Part I. Investment practices and techniques that are not
      identified in Part I do not apply to the Fund.

V     NET INCOME AND DISTRIBUTIONS

      MONEY MARKET FUNDS
      The net income attributable to each MFS Fund that is a money market fund
      is determined each day during which the New York Stock Exchange is open
      for trading (see "Determination of Net Asset Value" below for a list of
      days the Exchange is closed).

         For this purpose, the net income attributable to shares of a money
      market fund (from the time of the immediately preceding determination
      thereof) shall consist of (i) all interest income accrued on the portfolio
      assets of the money market fund, (ii) less all actual and accrued expenses
      of the money market fund determined in accordance with generally accepted
      accounting principles, and (iii) plus or minus net realized gains and
      losses and net unrealized appreciation or depreciation on the assets of
      the money market fund, if any. Interest income shall include discount
      earned (including both original issue and market discount) on discount
      paper accrued ratably to the date of maturity.

         Since the net income is declared as a dividend each time the net income
      is determined, the net asset value per share (i.e., the value of the net
      assets of the money market fund divided by the number of shares
      outstanding) remains at $1.00 per share immediately after each such
      determination and dividend declaration. Any increase in the value of a
      shareholder's investment, representing the reinvestment of dividend
      income, is reflected by an increase in the number of shares in the
      shareholder's account.

         It is expected that the shares of the money market fund will have a
      positive net income at the time of each determination thereof. If for any
      reason the net income determined at any time is a negative amount, which
      could occur, for instance, upon default by an issuer of a portfolio
      security, the money market fund would first offset the negative amount
      with respect to each shareholder account from the dividends declared
      during the month with respect to each such account. If and to the extent
      that such negative amount exceeds such declared dividends at the end of
      the month (or during the month in the case of an account liquidated in its
      entirety), the money market fund could reduce the number of its
      outstanding shares by treating each shareholder of the money market fund
      as having contributed to its capital that number of full and fractional
      shares of the money market fund in the account of such shareholder which
      represents its proportion of such excess. Each shareholder of the money
      market fund will be deemed to have agreed to such contribution in these
      circumstances by its investment in the money market fund. This procedure
      would permit the net asset value per share of the money market fund to be
      maintained at a constant $1.00 per share.

      OTHER FUNDS
      Each MFS Fund other than the MFS money market funds intends to distribute
      to its shareholders dividends equal to all of its net investment income
      with such frequency as is disclosed in the Fund's prospectus. These Funds'
      net investment income consists of non-capital gain income less expenses.
      In addition, these Funds intend to distribute net realized short- and
      long-term capital gains, if any, at least annually. Shareholders will be
      informed of the tax consequences of such distributions, including whether
      any portion represents a return of capital, after the end of each calendar
      year.

VI    TAX CONSIDERATIONS
      The following discussion is a brief summary of some of the important
      federal (and, where noted, state) income tax consequences affecting the
      Fund and its shareholders. The discussion is very general, and therefore
      prospective investors are urged to consult their tax advisors about the
      impact an investment in the Fund may have on their own tax situations.

      TAXATION OF THE FUND
      FEDERAL TAXES -- The Fund (even if it is a fund in a Trust with multiple
      series) is treated as a separate entity for federal income tax purposes
      under the Internal Revenue Code of 1986, as amended (the "Code"). The Fund
      has elected (or in the case of a new Fund, intends to elect) to be, and
      intends to qualify to be treated each year as, a "regulated investment
      company" under Subchapter M of the Code by meeting all applicable
      requirements of Subchapter M, including requirements as to the nature of
      the Fund's gross income, the amount of its distributions (as a percentage
      of both its overall income and any tax-exempt income), and the composition
      of its portfolio assets. As a regulated investment company, the Fund will
      not be subject to any federal income or excise taxes on its net investment
      income and net realized capital gains that it distributes to shareholders
      in accordance with the timing requirements imposed by the Code. The Fund's
      foreign-source income, if any, may be subject to foreign withholding
      taxes. If the Fund failed to qualify as a "regulated investment company"
      in any year, it would incur a regular federal corporate income tax on all
      of its taxable income, whether or not distributed, and Fund distributions
      would generally be taxable as ordinary dividend income to the
      shareholders.

      MASSACHUSETTS TAXES -- As long as it qualifies as a regulated investment
      company under the Code, the Fund will not be required to pay Massachusetts
      income or excise taxes.

      TAXATION OF SHAREHOLDERS
      TAX TREATMENT OF DISTRIBUTIONS -- Subject to the special rules discussed
      below for Municipal Funds, shareholders of the Fund normally will have to
      pay federal income tax and any state or local income taxes on the
      dividends and capital gain distributions they receive from the Fund. Any
      distributions from ordinary income and from net short-term capital gains
      are taxable to shareholders as ordinary income for federal income tax
      purposes whether paid in cash or reinvested in additional shares.
      Distributions of net capital gain (i.e., the excess of net long-term
      capital gain over net short-term capital loss), whether paid in cash or
      reinvested in additional shares, are taxable to shareholders as long-term
      capital gains for federal income tax purposes without regard to the length
      of time the shareholders have held their shares. Any Fund dividend that is
      declared in October, November, or December of any calendar year, payable
      to shareholders of record in such a month, and paid during the following
      January will be treated as if received by the shareholders on December 31
      of the year in which the dividend is declared. The Fund will notify
      shareholders regarding the federal tax status of its distributions after
      the end of each calendar year.

         Any Fund distribution, other than dividends that are declared by the
      Fund on a daily basis, will have the effect of reducing the per share net
      asset value of Fund shares by the amount of the distribution. Shareholders
      purchasing shares shortly before the record date of any such distribution
      (other than an exempt-interest dividend) may thus pay the full price for
      the shares and then effectively receive a portion of the purchase price
      back as a taxable distribution.

      DIVIDENDS-RECEIVED DEDUCTION -- If the Fund receives dividend income from
      U.S. corporations, a portion of the Fund's ordinary income dividends is
      normally eligible for the dividends-received deduction for corporations if
      the recipient otherwise qualifies for that deduction with respect to its
      holding of Fund shares. Availability of the deduction for particular
      corporate shareholders is subject to certain limitations, and deducted
      amounts may be subject to the alternative minimum tax or result in certain
      basis adjustments.

      DISPOSITION OF SHARES -- In general, any gain or loss realized upon a
      disposition of Fund shares by a shareholder that holds such shares as a
      capital asset will be treated as a long-term capital gain or loss if the
      shares have been held for more than twelve months and otherwise as a
      short-term capital gain or loss. However, any loss realized upon a
      disposition of Fund shares held for six months or less will be treated as
      a long-term capital loss to the extent of any distributions of net capital
      gain made with respect to those shares. Any loss realized upon a
      disposition of shares may also be disallowed under rules relating to "wash
      sales." Gain may be increased (or loss reduced) upon a redemption of Class
      A Fund shares held for 90 days or less followed by any purchase (including
      purchases by exchange or by reinvestment) without payment of an additional
      sales charge of Class A shares of the Fund or of any other shares of an
      MFS Fund generally sold subject to a sales charge.

      DISTRIBUTION/ACCOUNTING POLICIES -- The Fund's current distribution and
      accounting policies will affect the amount, timing, and character of
      distributions to shareholders and may, under certain circumstances, make
      an economic return of capital taxable to shareholders.

      U.S. TAXATION OF NON-U.S. PERSONS -- Dividends and certain other payments
      (but not including distributions of net capital gains) to persons who are
      not citizens or residents of the United States or U.S. entities ("Non-U.S.
      Persons") are generally subject to U.S. tax withholding at the rate of
      30%. The Fund intends to withhold at that rate on taxable dividends and
      other payments to Non-U.S. Persons that are subject to such withholding.
      The Fund may withhold at a lower rate permitted by an applicable treaty if
      the shareholder provides the documentation required by the Fund. Any
      amounts overwithheld may be recovered by such persons by filing a claim
      for refund with the U.S. Internal Revenue Service within the time period
      appropriate to such claims.

      BACKUP WITHHOLDING -- The Fund is also required in certain circumstances
      to apply backup withholding at the rate of 31% on taxable dividends and
      capital gain distributions (and redemption proceeds, if applicable) paid
      to any non-corporate shareholder (including a Non-U.S. Person) who does
      not furnish to the Fund certain information and certifications or who is
      otherwise subject to backup withholding. Backup withholding will not,
      however, be applied to payments that have been subject to 30% withholding.

      FOREIGN INCOME TAXATION OF NON-U.S. PERSONS -- Distributions received from
      the Fund by Non-U.S. Persons may also be subject to tax under the laws of
      their own jurisdictions.

      STATE AND LOCAL INCOME TAXES: U.S. GOVERNMENT SECURITIES -- Dividends paid
      by the Fund that are derived from interest on obligations of the U.S.
      Government and certain of its agencies and instrumentalities (but
      generally not distributions of capital gains realized upon the disposition
      of such obligations) may be exempt from state and local income taxes. The
      Fund generally intends to advise shareholders of the extent, if any, to
      which its dividends consist of such interest. Shareholders are urged to
      consult their tax advisors regarding the possible exclusion of such
      portion of their dividends for state and local income tax purposes.

      CERTAIN SPECIFIC INVESTMENTS -- Any investment in zero coupon bonds,
      deferred interest bonds, payment-in-kind bonds, certain stripped
      securities, and certain securities purchased at a market discount will
      cause the Fund to recognize income prior to the receipt of cash payments
      with respect to those securities. To distribute this income (as well as
      non-cash income described in the next two paragraphs) and avoid a tax on
      the Fund, the Fund may be required to liquidate portfolio securities that
      it might otherwise have continued to hold, potentially resulting in
      additional taxable gain or loss to the Fund. Any investment in residual
      interests of a CMO that has elected to be treated as a real estate
      mortgage investment conduit, or "REMIC," can create complex tax problems,
      especially if the Fund has state or local governments or other tax-exempt
      organizations as shareholders.

      OPTIONS, FUTURES CONTRACTS, AND FORWARD CONTRACTS -- The Fund's
      transactions in options, Futures Contracts, Forward Contracts, short sales
      "against the box," and swaps and related transactions will be subject to
      special tax rules that may affect the amount, timing, and character of
      Fund income and distributions to shareholders. For example, certain
      positions held by the Fund on the last business day of each taxable year
      will be marked to market (i.e., treated as if closed out) on that day, and
      any gain or loss associated with the positions will be treated as 60%
      long-term and 40% short-term capital gain or loss. Certain positions held
      by the Fund that substantially diminish its risk of loss with respect to
      other positions in its portfolio may constitute "straddles," and may be
      subject to special tax rules that would cause deferral of Fund losses,
      adjustments in the holding periods of Fund securities, and conversion of
      short-term into long-term capital losses. Certain tax elections exist for
      straddles that may alter the effects of these rules. The Fund will limit
      its activities in options, Futures Contracts, Forward Contracts, short
      sales "against the box" and swaps and related transactions to the extent
      necessary to meet the requirements of Subchapter M of the Code.

      FOREIGN INVESTMENTS -- Special tax considerations apply with respect to
      foreign investments by the Fund. Foreign exchange gains and losses
      realized by the Fund may be treated as ordinary income and loss. Use of
      foreign currencies for non-hedging purposes and investment by the Fund in
      certain "passive foreign investment companies" may be limited in order to
      avoid a tax on the Fund. The Fund may elect to mark to market any
      investments in "passive foreign investment companies" on the last day of
      each year. This election may cause the Fund to recognize income prior to
      the receipt of cash payments with respect to those investments; in order
      to distribute this income and avoid a tax on the Fund, the Fund may be
      required to liquidate portfolio securities that it might otherwise have
      continued to hold, potentially resulting in additional taxable gain or
      loss to the Fund.

      FOREIGN INCOME TAXES -- Investment income received by the Fund and gains
      with respect to foreign securities may be subject to foreign income taxes
      withheld at the source. The United States has entered into tax treaties
      with many foreign countries that may entitle the Fund to a reduced rate of
      tax or an exemption from tax on such income; the Fund intends to qualify
      for treaty reduced rates where available. It is not possible, however, to
      determine the Fund's effective rate of foreign tax in advance, since the
      amount of the Fund's assets to be invested within various countries is not
      known.

         If the Fund holds more than 50% of its assets in foreign stock and
      securities at the close of its taxable year, it may elect to "pass
      through" to its shareholders foreign income taxes paid by it. If the Fund
      so elects, shareholders will be required to treat their pro rata portions
      of the foreign income taxes paid by the Fund as part of the amounts
      distributed to them by it and thus includable in their gross income for
      federal income tax purposes. Shareholders who itemize deductions would
      then be allowed to claim a deduction or credit (but not both) on their
      federal income tax returns for such amounts, subject to certain
      limitations. Shareholders who do not itemize deductions would (subject to
      such limitations) be able to claim a credit but not a deduction. No
      deduction will be permitted to individuals in computing their alternative
      minimum tax liability. If the Fund is not eligible, or does not elect, to
      "pass through" to its shareholders foreign income taxes it has paid,
      shareholders will not be able to claim any deduction or credit for any
      part of the foreign taxes paid by the Fund.

      SPECIAL RULES FOR MUNICIPAL FUND DISTRIBUTIONS The following special rules
      apply to shareholders of funds whose objective is to invest primarily in
      obligations that pay interest that is exempt from federal income tax
      ("Municipal Funds").

      TAX EXEMPT DISTRIBUTIONS -- The portion of a Municipal Fund's
      distributions of net investment income that is attributable to interest
      from tax-exempt securities will be designated by the Fund as an "exempt-
      interest dividend" under the Code and will generally be exempt from
      federal income tax in the hands of shareholders so long as at least 50% of
      the total value of the Fund's assets consists of tax-exempt securities at
      the close of each quarter of the Fund's taxable year. Distributions of
      tax-exempt interest earned from certain securities may, however, be
      treated as an item of tax preference for shareholders under the federal
      alternative minimum tax, and all exempt-interest dividends may increase a
      corporate shareholder's alternative minimum tax. Except when the Fund
      provides actual monthly percentage breakdowns, the percentage of income
      designated as tax-exempt will be applied uniformly to all distributions by
      the Fund of net investment income made during each fiscal year of the Fund
      and may differ from the percentage of distributions consisting of
      tax-exempt interest in any particular month. Shareholders are required to
      report exempt-interest dividends received from the Fund on their federal
      income tax returns.

      TAXABLE DISTRIBUTIONS -- A Municipal Fund may also earn some income that
      is taxable (including interest from any obligations that lose their
      federal tax exemption) and may recognize capital gains and losses as a
      result of the disposition of securities and from certain options and
      futures transactions. Shareholders normally will have to pay federal
      income tax on the non-exempt-interest dividends and capital gain
      distributions they receive from the Fund, whether paid in cash or
      reinvested in additional shares. However, the Fund does not expect that
      the non-tax-exempt portion of its net investment income, if any, will be
      substantial. Because the Fund expects to earn primarily tax-exempt
      interest income, it is expected that no Fund dividends will qualify for
      the dividends-received deduction for corporations.

      CONSEQUENCES OF DISTRIBUTIONS BY A MUNICIPAL FUND: EFFECT OF ACCRUED TAX-
      EXEMPT INCOME -- Shareholders redeeming shares after tax-exempt income has
      been accrued but not yet declared as a dividend should be aware that a
      portion of the proceeds realized upon redemption of the shares will
      reflect the existence of such accrued tax-exempt income and that this
      portion will be subject to tax as a capital gain even though it would have
      been tax-exempt had it been declared as a dividend prior to the
      redemption. For this reason, if a shareholder wishes to redeem shares of a
      Municipal Fund that does not declare dividends on a daily basis, the
      shareholder may wish to consider whether he or she could obtain a better
      tax result by redeeming immediately after the Fund declares dividends
      representing substantially all the ordinary income (including tax-exempt
      income) accrued for that month.

      CERTAIN ADDITIONAL INFORMATION FOR MUNICIPAL FUND SHAREHOLDERS -- Interest
      on indebtedness incurred by shareholders to purchase or carry Fund shares
      will not be deductible for federal income tax purposes. Exempt-interest
      dividends are taken into account in calculating the amount of social
      security and railroad retirement benefits that may be subject to federal
      income tax. Entities or persons who are "substantial users" (or persons
      related to "substantial users") of facilities financed by private activity
      bonds should consult their tax advisors before purchasing Fund shares.

      CONSEQUENCES OF REDEMPTION OF SHARES -- Any loss realized on a redemption
      of Municipal Fund shares held for six months or less will be disallowed to
      the extent of any exempt-interest dividends received with respect to those
      shares. If not disallowed, any such loss will be treated as a long-term
      capital loss to the extent of any distributions of net capital gain made
      with respect to those shares.

      STATE AND LOCAL INCOME TAXES: MUNICIPAL OBLIGATIONS -- The exemption of
      exempt-interest dividends for federal income tax purposes does not
      necessarily result in exemption under the income tax laws of any state or
      local taxing authority. Some states do exempt from tax that portion of an
      exempt-interest dividend that represents interest received by a regulated
      investment company on its holdings of securities issued by that state and
      its political subdivisions and instrumentalities. Therefore, the Fund will
      report annually to its shareholders the percentage of interest income
      earned by it during the preceding year on Municipal Bonds and will
      indicate, on a state-by-state basis only, the source of such income.

VII   PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS
      Specific decisions to purchase or sell securities for the Fund are made by
      persons affiliated with the Adviser. Any such person may serve other
      clients of the Adviser, or any subsidiary of the Adviser in a similar
      capacity. Changes in the Fund's investments are reviewed by the Trust's
      Board of Trustees.

         The primary consideration in placing portfolio security transactions is
      execution at the most favorable prices. The Adviser has complete freedom
      as to the markets in and broker-dealers through which it seeks this
      result. In the U.S. and in some other countries debt securities are traded
      principally in the over-the-counter market on a net basis through dealers
      acting for their own account and not as brokers. In other countries both
      debt and equity securities are traded on exchanges at fixed commission
      rates. The cost of securities purchased from underwriters includes an
      underwriter's commission or concession, and the prices at which securities
      are purchased and sold from and to dealers include a dealer's mark-up or
      mark-down. The Adviser normally seeks to deal directly with the primary
      market makers or on major exchanges unless, in its opinion, better prices
      are available elsewhere. Subject to the requirement of seeking execution
      at the best available price, securities may, as authorized by the Advisory
      Agreement, be bought from or sold to dealers who have furnished
      statistical, research and other information or services to the Adviser. At
      present no arrangements for the recapture of commission payments are in
      effect.

         Consistent with the foregoing primary consideration, the Conduct Rules
      of the National Association of Securities Dealers, Inc. ("NASD") and such
      other policies as the Trustees may determine, the Adviser may consider
      sales of shares of the Fund and of the other investment company clients of
      MFD as a factor in the selection of broker-dealers to execute the Fund's
      portfolio transactions.

         Under the Advisory Agreement and as permitted by Section 28(e) of the
      Securities Exchange Act of 1934, the Adviser may cause the Fund to pay a
      broker-dealer which provides brokerage and research services to the
      Adviser, an amount of commission for effecting a securities transaction
      for the Fund in excess of the amount other broker-dealers would have
      charged for the transaction, if the Adviser determines in good faith that
      the greater commission is reasonable in relation to the value of the
      brokerage and research services provided by the executing broker-dealer
      viewed in terms of either a particular transaction or their respective
      overall responsibilities to the Fund or to their other clients. Not all of
      such services are useful or of value in advising the Fund.

         The term "brokerage and research services" includes advice as to the
      value of securities, the advisability of investing in, purchasing or
      selling securities, and the availability of securities or of purchasers or
      sellers of securities; furnishing analyses and reports concerning issues,
      industries, securities, economic factors and trends, portfolio strategy
      and the performance of accounts; and effecting securities transactions and
      performing functions incidental thereto, such as clearance and settlement.

         Although commissions paid on every transaction will, in the judgment of
      the Adviser, be reasonable in relation to the value of the brokerage
      services provided, commissions exceeding those which another broker might
      charge may be paid to broker-dealers who were selected to execute
      transactions on behalf of the Fund and the Adviser's other clients in part
      for providing advice as to the availability of securities or of purchasers
      or sellers of securities and services in effecting securities transactions
      and performing functions incidental thereto, such as clearance and
      settlement.

         Broker-dealers may be willing to furnish statistical, research and
      other factual information or services ("Research") to the Adviser for no
      consideration other than brokerage or underwriting commissions. Securities
      may be bought or sold from time to time through such broker-dealers, on
      behalf of the Fund.

         The Adviser's investment management personnel attempt to evaluate the
      quality of Research provided by brokers. The Adviser sometimes uses
      evaluations resulting from this effort as a consideration in the selection
      of brokers to execute portfolio transactions.

         The management fee of the Adviser will not be reduced as a consequence
      of the Adviser's receipt of brokerage and research service. To the extent
      the Fund's portfolio transactions are used to obtain brokerage and
      research services, the brokerage commissions paid by the Fund will exceed
      those that might otherwise be paid for such portfolio transactions, or for
      such portfolio transactions and research, by an amount which cannot be
      presently determined. Such services would be useful and of value to the
      Adviser in serving both the Fund and other clients and, conversely, such
      services obtained by the placement of brokerage business of other clients
      would be useful to the Adviser in carrying out its obligations to the
      Fund. While such services are not expected to reduce the expenses of the
      Adviser, the Adviser would, through use of the services, avoid the
      additional expenses which would be incurred if it should attempt to
      develop comparable information through its own staff.

         In certain instances there may be securities which are suitable for the
      Fund's portfolio as well as for that of one or more of the other clients
      of the Adviser or any subsidiary of the Adviser. Investment decisions for
      the Fund and for such other clients are made with a view to achieving
      their respective investment objectives. It may develop that a particular
      security is bought or sold for only one client even though it might be
      held by, or bought or sold for, other clients. Likewise, a particular
      security may be bought for one or more clients when one or more other
      clients are selling that same security. Some simultaneous transactions are
      inevitable when several clients receive investment advice from the same
      investment adviser, particularly when the same security is suitable for
      the investment objectives of more than one client. When two or more
      clients are simultaneously engaged in the purchase or sale of the same
      security, the securities are allocated among clients in a manner believed
      by the adviser to be equitable to each. It is recognized that in some
      cases this system could have a detrimental effect on the price or volume
      of the security as far as the Fund is concerned. In other cases, however,
      the Fund believes that its ability to participate in volume transactions
      will produce better executions for the Fund.

VIII  DETERMINATION OF NET ASSET VALUE
      The net asset value per share of each class of the Fund is determined each
      day during which the New York Stock Exchange is open for trading. (As of
      the date of this SAI, the Exchange is open for trading every weekday
      except for the following holidays (or the days on which they are
      observed): New Year's Day; Martin Luther King Day; Presidents' Day; Good
      Friday; Memorial Day; Independence Day; Labor Day; Thanksgiving Day and
      Christmas Day.) This determination is made once each day as of the close
      of regular trading on the Exchange by deducting the amount of the
      liabilities attributable to the class from the value of the assets
      attributable to the class and dividing the difference by the number of
      shares of the class outstanding.

      MONEY MARKET FUNDS
      Portfolio securities of each MFS Fund that is a money market fund are
      valued at amortized cost, which the Board of Trustees which oversees the
      money market fund has determined in good faith constitutes fair value for
      the purposes of complying with the 1940 Act. This valuation method will
      continue to be used until such time as the Board of Trustees determines
      that it does not constitute fair value for such purposes. Each money
      market fund will limit its portfolio to those investments in U.S.
      dollar-denominated instruments which its Board of Trustees determines
      present minimal credit risks, and which are of high quality as determined
      by any major rating service or, in the case of any instrument that is not
      so rated, of comparable quality as determined by the Board of Trustees.
      Each money market fund has also agreed to maintain a dollar-weighted
      average maturity of 90 days or less and to invest only in securities
      maturing in 13 months or less. The Board of Trustees which oversees each
      money market fund has established procedures designed to stabilize its net
      asset value per share, as computed for the purposes of sales and
      redemptions, at $1.00 per share. If the Board determines that a deviation
      from the $1.00 per share price may exist which may result in a material
      dilution or other unfair result to investors or existing shareholders, it
      will take corrective action it regards as necessary and appropriate, which
      action could include the sale of instruments prior to maturity (to realize
      capital gains or losses); shortening average portfolio maturity;
      withholding dividends; or using market quotations for valuation purposes.

      OTHER FUNDS
      The following valuation techniques apply to each MFS Fund that is not a
      money market fund.

         Equity securities in the Fund's portfolio are valued at the last sale
      price on the exchange on which they are primarily traded or on the Nasdaq
      stock market system for unlisted national market issues, or at the last
      quoted bid price for listed securities in which there were no sales during
      the day or for unlisted securities not reported on the Nasdaq stock market
      system. Bonds and other fixed income securities (other than short-term
      obligations) of U.S. issuers in the Fund's portfolio are valued on the
      basis of valuations furnished by a pricing service which utilizes both
      dealer-supplied valuations and electronic data processing techniques which
      take into account appropriate factors such as institutional-size trading
      in similar groups of securities, yield, quality, coupon rate, maturity,
      type of issue, trading characteristics and other market data without
      exclusive reliance upon quoted prices or exchange or over-the-counter
      prices, since such valuations are believed to reflect more accurately the
      fair value of such securities. Forward Contracts will be valued using a
      pricing model taking into consideration market data from an external
      pricing source. Use of the pricing services has been approved by the Board
      of Trustees.

         All other securities, futures contracts and options in the Fund's
      portfolio (other than short-term obligations) for which the principal
      market is one or more securities or commodities exchanges (whether
      domestic or foreign) will be valued at the last reported sale price or at
      the settlement price prior to the determination (or if there has been no
      current sale, at the closing bid price) on the primary exchange on which
      such securities, futures contracts or options are traded; but if a
      securities exchange is not the principal market for securities, such
      securities will, if market quotations are readily available, be valued at
      current bid prices, unless such securities are reported on the Nasdaq
      stock market system, in which case they are valued at the last sale price
      or, if no sales occurred during the day, at the last quoted bid price.
      Short-term obligations in the Fund's portfolio are valued at amortized
      cost, which constitutes fair value as determined by the Board of Trustees.
      Short-term obligations with a remaining maturity in excess of 60 days will
      be valued upon dealer supplied valuations. Portfolio investments for which
      there are no such quotations or valuations are valued at fair value as
      determined in good faith by or at the direction of the Board of Trustees.

         Generally, trading in foreign securities is substantially completed
      each day at various times prior to the close of regular trading on the
      Exchange. Occasionally, events affecting the values of such securities may
      occur between the times at which they are determined and the close of
      regular trading on the Exchange which will not be reflected in the
      computation of the Fund's net asset value unless the Trustees deem that
      such event would materially affect the net asset value in which case an
      adjustment would be made.

         All investments and assets are expressed in U.S. dollars based upon
      current currency exchange rates. A share's net asset value is effective
      for orders received by the dealer prior to its calculation and received by
      MFD prior to the close of that business day.

IX    PERFORMANCE INFORMATION

      MONEY MARKET FUNDS
      Each MFS Fund that is a money market fund will provide current annualized
      and effective annualized yield quotations based on the daily dividends of
      shares of the money market fund. These quotations may from time to time be
      used in advertisements, shareholder reports or other communications to
      shareholders.

         Any current yield quotation of a money market fund which is used in
      such a manner as to be subject to the provisions of Rule 482(d) under the
      1933 Act shall consist of an annualized historical yield, carried at least
      to the nearest hundredth of one percent based on a specific seven calendar
      day period and shall be calculated by dividing the net change in the value
      of an account having a balance of one share of that class at the beginning
      of the period by the value of the account at the beginning of the period
      and multiplying the quotient by 365/7. For this purpose the net change in
      account value would reflect the value of additional shares purchased with
      dividends declared on the original share and dividends declared on both
      the original share and any such additional shares, but would not reflect
      any realized gains or losses from the sale of securities or any unrealized
      appreciation or depreciation on portfolio securities. In addition, any
      effective yield quotation of a money market fund so used shall be
      calculated by compounding the current yield quotation for such period by
      multiplying such quotation by 7/365, adding 1 to the product, raising the
      sum to a power equal to 365/7, and subtracting 1 from the result. These
      yield quotations should not be considered as representative of the yield
      of a money market fund in the future since the yield will vary based on
      the type, quality and maturities of the securities held in its portfolio,
      fluctuations in short-term interest rates and changes in the money market
      fund's expenses.

      OTHER FUNDS
      Each MFS Fund that is not a money market fund may quote the following
      performance results.

      TOTAL RATE OF RETURN -- The Fund will calculate its total rate of return
      for each class of shares for certain periods by determining the average
      annual compounded rates of return over those periods that would cause an
      investment of $1,000 (made with all distributions reinvested and
      reflecting the CDSC or the maximum public offering price) to reach the
      value of that investment at the end of the periods. The Fund may also
      calculate (i) a total rate of return, which is not reduced by any
      applicable CDSC and therefore may result in a higher rate of return, (ii)
      a total rate of return assuming an initial account value of $1,000, which
      will result in a higher rate of return since the value of the initial
      account will not be reduced by any applicable sales charge and/or (iii)
      total rates of return which represent aggregate performance over a period
      or year- by-year performance, and which may or may not reflect the effect
      of the maximum or other sales charge or CDSC.

         The Fund offers multiple classes of shares which were initially offered
      for sale to, and purchased by, the public on different dates (the class
      "inception date"). The calculation of total rate of return for a class of
      shares which has a later class inception date than another class of shares
      of the Fund is based both on (i) the performance of the Fund's newer class
      from its inception date and (ii) the performance of the Fund's oldest
      class from its inception date up to the class inception date of the newer
      class.

         As discussed in the Prospectus, the sales charges, expenses and expense
      ratios, and therefore the performance, of the Fund's classes of shares
      differ. In calculating total rate of return for a newer class of shares in
      accordance with certain formulas required by the SEC, the performance will
      be adjusted to take into account the fact that the newer class is subject
      to a different sales charge than the oldest class (e.g., if the newer
      class is Class A shares, the total rate of return quoted will reflect the
      deduction of the initial sales charge applicable to Class A shares; if the
      newer class is Class B shares, the total rate of return quoted will
      reflect the deduction of the CDSC applicable to Class B shares). However,
      the performance will not be adjusted to take into account the fact that
      the newer class of shares bears different class specific expenses than the
      oldest class of shares (e.g., Rule 12b-1 fees). Therefore, the total rate
      of return quoted for a newer class of shares will differ from the return
      that would be quoted had the newer class of shares been outstanding for
      the entire period over which the calculation is based (i.e., the total
      rate of return quoted for the newer class will be higher than the return
      that would have been quoted had the newer class of shares been outstanding
      for the entire period over which the calculation is based if the class
      specific expenses for the newer class are higher than the class specific
      expenses of the oldest class, and the total rate of return quoted for the
      newer class will be lower than the return that would be quoted had the
      newer class of shares been outstanding for this entire period if the class
      specific expenses for the newer class are lower than the class specific
      expenses of the oldest class).

         Any total rate of return quotation provided by the Fund should not be
      considered as representative of the performance of the Fund in the future
      since the net asset value of shares of the Fund will vary based not only
      on the type, quality and maturities of the securities held in the Fund's
      portfolio, but also on changes in the current value of such securities and
      on changes in the expenses of the Fund. These factors and possible
      differences in the methods used to calculate total rates of return should
      be considered when comparing the total rate of return of the Fund to total
      rates of return published for other investment companies or other
      investment vehicles. Total rate of return reflects the performance of both
      principal and income. Current net asset value and account balance
      information may be obtained by calling 1-800-MFS-TALK (637-8255).

      YIELD -- Any yield quotation for a class of shares of the Fund is based on
      the annualized net investment income per share of that class for the 30-
      day period. The yield for each class of the Fund is calculated by dividing
      the net investment income allocated to that class earned during the period
      by the maximum offering price per share of that class of the Fund on the
      last day of the period. The resulting figure is then annualized. Net
      investment income per share of a class is determined by dividing (i) the
      dividends and interest allocated to that class during the period, minus
      accrued expense of that class for the period by (ii) the average number of
      shares of the class entitled to receive dividends during the period
      multiplied by the maximum offering price per share on the last day of the
      period. The Fund's yield calculations assume a maximum sales charge of
      5.75% in the case of Class A shares and no payment of any CDSC in the case
      of Class B and Class C shares.

      TAX-EQUIVALENT YIELD -- The tax-equivalent yield for a class of shares of
      a Fund is calculated by determining the rate of return that would have to
      be achieved on a fully taxable investment in such shares to produce the
      after-tax equivalent of the yield of that class. In calculating tax-
      equivalent yield, a Fund assumes certain federal tax brackets for
      shareholders and does not take into account state taxes.

      CURRENT DISTRIBUTION RATE -- Yield, which is calculated according to a
      formula prescribed by the Securities and Exchange Commission, is not
      indicative of the amounts which were or will be paid to the Fund's
      shareholders. Amounts paid to shareholders of each class are reflected in
      the quoted "current distribution rate" for that class. The current
      distribution rate for a class is computed by (i) annualizing the
      distributions (excluding short-term capital gains) of the class for a
      stated period; (ii) adding any short-term capital gains paid within the
      immediately preceding twelve-month period; and (iii) dividing the result
      by the maximum offering price or net asset value per share on the last day
      of the period. The current distribution rate differs from the yield
      computation because it may include distributions to shareholders from
      sources other than dividends and interest, such as premium income for
      option writing, short-term capital gains and return of invested capital,
      and may be calculated over a different period of time. The Fund's current
      distribution rate calculation for Class B shares and Class C shares
      assumes no CDSC is paid.

      GENERAL
      From time to time the Fund may, as appropriate, quote Fund rankings or
      reprint all or a portion of evaluations of fund performance and operations
      appearing in various independent publications, including but not limited
      to the following: Money, Fortune, U.S. News and World Report, Kiplinger's
      Personal Finance, The Wall Street Journal, Barron's, Investors Business
      Daily, Newsweek, Financial World, Financial Planning, Investment Advisor,
      USA Today, Pensions and Investments, SmartMoney, Forbes, Global Finance,
      Registered Representative, Institutional Investor, the Investment Company
      Institute, Johnson's Charts, Morningstar, Lipper Analytical Securities
      Corporation, CDA Wiesenberger, Shearson Lehman and Salomon Bros. Indices,
      Ibbotson, Business Week, Lowry Associates, Media General, Investment
      Company Data, The New York Times, Your Money, Strangers Investment
      Advisor, Financial Planning on Wall Street, Standard and Poor's,
      Individual Investor, The 100 Best Mutual Funds You Can Buy, by Gordon K.
      Williamson, Consumer Price Index, and Sanford C. Bernstein & Co. Fund
      performance may also be compared to the performance of other mutual funds
      tracked by financial or business publications or periodicals. The Fund may
      also quote evaluations mentioned in independent radio or television
      broadcasts and use charts and graphs to illustrate the past performance of
      various indices such as those mentioned above and illustrations using
      hypothetical rates of return to illustrate the effects of compounding and
      tax-deferral. The Fund may advertise examples of the effects of periodic
      investment plans, including the principle of dollar cost averaging. In
      such a program, an investor invests a fixed dollar amount in a fund at
      periodic intervals, thereby purchasing fewer shares when prices are high
      and more shares when prices are low. While such a strategy does not assure
      a profit or guard against a loss in a declining market, the investor's
      average cost per share can be lower than if fixed numbers of shares are
      purchased at the same intervals.

         From time to time, the Fund may discuss or quote its current portfolio
      manager as well as other investment personnel, including such persons'
      views on: the economy; securities markets; portfolio securities and their
      issuers; investment philosophies, strategies, techniques and criteria used
      in the selection of securities to be purchased or sold for the Fund; the
      Fund's portfolio holdings; the investment research and analysis process;
      the formulation and evaluation of investment recommendations; and the
      assessment and evaluation of credit, interest rate, market and economic
      risks, and similar or related matters.

         The Fund may also use charts, graphs or other presentation formats to
      illustrate the historical correlation of its performance to fund
      categories established by Morningstar (or other nationally recognized
      statistical ratings organizations) and to other MFS Funds.


         From time to time the Fund may also discuss or quote the views of its
      distributor, its investment adviser and other financial planning, legal,
      tax, accounting, insurance, estate planning and other professionals, or
      from surveys, regarding individual and family financial planning. Such
      views may include information regarding: retirement planning, including
      issues concerning social security; tax management strategies; estate
      planning; general investment techniques (e.g., asset allocation and
      disciplined saving and investing); business succession; ideas and
      information provided through the MFS Heritage Planning(SM) program, an
      intergenerational financial planning assistance program; issues with
      respect to insurance (e.g., disability and life insurance and Medicare
      supplemental insurance); issues regarding financial and health care
      management for elderly family members; the history of the mutual fund
      industry; investor behavior; and other similar or related matters.


         From time to time, the Fund may also advertise annual returns showing
      the cumulative value of an initial investment in the Fund in various
      amounts over specified periods, with capital gain and dividend
      distributions invested in additional shares or taken in cash, and with no
      adjustment for any income taxes (if applicable) payable by shareholders.

         managers of companies with significant labor contracts, academics and
         other national labor leaders or experts.

X     SHAREHOLDER SERVICES

      INVESTMENT AND WITHDRAWAL PROGRAMS
      The Fund makes available the following programs designed to enable
      shareholders to add to their investment or withdraw from it with a minimum
      of paper work. These programs are described below and, in certain cases,
      in the Prospectus. The programs involve no extra charge to shareholders
      (other than a sales charge in the case of certain Class A share purchases)
      and may be changed or discontinued at any time by a shareholder or the
      Fund.

      LETTER OF INTENT -- If a shareholder (other than a group purchaser
      described below) anticipates purchasing $50,000 or more of Class A shares
      of the Fund alone or in combination with shares of any class of MFS Funds
      or MFS Fixed Fund (a bank collective investment fund) within a 13-month
      period (or 36-month period, in the case of purchases of $1 million or
      more), the shareholder may obtain Class A shares of the Fund at the same
      reduced sales charge as though the total quantity were invested in one
      lump sum by completing the Letter of Intent section of the Account
      Application or filing a separate Letter of Intent application (available
      from MFSC) within 90 days of the commencement of purchases. Subject to
      acceptance by MFD and the conditions mentioned below, each purchase will
      be made at a public offering price applicable to a single transaction of
      the dollar amount specified in the Letter of Intent application. The
      shareholder or his dealer must inform MFD that the Letter of Intent is in
      effect each time shares are purchased. The shareholder makes no commitment
      to purchase additional shares, but if his purchases within 13 months (or
      36 months in the case of purchases of $1 million or more) plus the value
      of shares credited toward completion of the Letter of Intent do not total
      the sum specified, he will pay the increased amount of the sales charge as
      described below. Instructions for issuance of shares in the name of a
      person other than the person signing the Letter of Intent application must
      be accompanied by a written statement from the dealer stating that the
      shares were paid for by the person signing such Letter. Neither income
      dividends nor capital gain distributions taken in additional shares will
      apply toward the completion of the Letter of Intent. Dividends and
      distributions of other MFS Funds automatically reinvested in shares of the
      Fund pursuant to the Distribution Investment Program will also not apply
      toward completion of the Letter of Intent.

         Out of the shareholder's initial purchase (or subsequent purchases if
      necessary), 5% of the dollar amount specified in the Letter of Intent
      application shall be held in escrow by MFSC in the form of shares
      registered in the shareholder's name. All income dividends and capital
      gain distributions on escrowed shares will be paid to the shareholder or
      to his order. When the minimum investment so specified is completed
      (either prior to or by the end of the 13-month period or 36-month period,
      as applicable), the shareholder will be notified and the escrowed shares
      will be released.

         If the intended investment is not completed, MFSC will redeem an
      appropriate number of the escrowed shares in order to realize such
      difference. Shares remaining after any such redemption will be released by
      MFSC. By completing and signing the Account Application or separate Letter
      of Intent application, the shareholder irrevocably appoints MFSC his
      attorney to surrender for redemption any or all escrowed shares with full
      power of substitution in the premises.

      RIGHT OF ACCUMULATION -- A shareholder qualifies for cumulative quantity
      discounts on the purchase of Class A shares when his new investment,
      together with the current offering price value of all holdings of Class A,
      Class B and Class C shares of that shareholder in the MFS Funds or MFS
      Fixed Fund reaches a discount level. See "Purchases" in the Prospectus for
      the sales charges on quantity discounts. A shareholder must provide MFSC
      (or his investment dealer must provide MFD) with information to verify
      that the quantity sales charge discount is applicable at the time the
      investment is made.

      SUBSEQUENT INVESTMENT BY TELEPHONE -- Each shareholder may purchase
      additional shares of any MFS Fund by telephoning MFSC toll-free at (800)
      225-2606. The minimum purchase amount is $50 and the maximum purchase
      amount is $100,000. Shareholders wishing to avail themselves of this
      telephone purchase privilege must so elect on their Account Application
      and designate thereon a bank and account number from which purchases will
      be made. If a telephone purchase request is received by MFSC on any
      business day prior to the close of regular trading on the Exchange
      (generally, 4:00 p.m., Eastern time), the purchase will occur at the
      closing net asset value of the shares purchased on that day. MFSC may be
      liable for any losses resulting from unauthorized telephone transactions
      if it does not follow reasonable procedures designed to verify the
      identity of the caller. MFSC will request personal or other information
      from the caller, and will normally also record calls. Shareholders should
      verify the accuracy of confirmation statements immediately after their
      receipt.

      DISTRIBUTION INVESTMENT PROGRAM -- Distributions of dividends and capital
      gains made by the Fund with respect to a particular class of shares may be
      automatically invested in shares of the same class of one of the other MFS
      Funds, if shares of that fund are available for sale. Such investments
      will be subject to additional purchase minimums. Distributions will be
      invested at net asset value (exclusive of any sales charge) and will not
      be subject to any CDSC. Distributions will be invested at the close of
      business on the payable date for the distribution. A shareholder
      considering the Distribution Investment Program should obtain and read the
      prospectus of the other fund and consider the differences in objectives
      and policies before making any investment.

      SYSTEMATIC WITHDRAWAL PLAN -- A shareholder may direct MFSC to send him
      (or anyone he designates) regular periodic payments based upon the value
      of his account. Each payment under a Systematic Withdrawal Plan ("SWP")
      must be at least $100, except in certain limited circumstances. The
      aggregate withdrawals of Class B and Class C shares in any year pursuant
      to a SWP generally are limited to 10% of the value of the account at the
      time of establishment of the SWP. SWP payments are drawn from the proceeds
      of share redemptions (which would be a return of principal and, if
      reflecting a gain, would be taxable). Redemptions of Class B and Class C
      shares will be made in the following order: (i) shares representing
      reinvested distributions; (ii) shares representing undistributed capital
      gains and income; and (iii) to the extent necessary, shares representing
      direct investments subject to the lowest CDSC. The CDSC will be waived in
      the case of redemptions of Class B and Class C shares pursuant to a SWP,
      but will not be waived in the case of SWP redemptions of Class A shares
      which are subject to a CDSC. To the extent that redemptions for such
      periodic withdrawals exceed dividend income reinvested in the account,
      such redemptions will reduce and may eventually exhaust the number of
      shares in the shareholder's account. All dividend and capital gain
      distributions for an account with a SWP will be received in full and
      fractional shares of the Fund at the net asset value in effect at the
      close of business on the record date for such distributions. To initiate
      this service, shares having an aggregate value of at least $5,000 either
      must be held on deposit by, or certificates for such shares must be
      deposited with, MFSC. With respect to Class A shares, maintaining a
      withdrawal plan concurrently with an investment program would be
      disadvantageous because of the sales charges included in share purchases
      and the imposition of a CDSC on certain redemptions. The shareholder may
      deposit into the account additional shares of the Fund, change the payee
      or change the dollar amount of each payment. MFSC may charge the account
      for services rendered and expenses incurred beyond those normally assumed
      by the Fund with respect to the liquidation of shares. No charge is
      currently assessed against the account, but one could be instituted by
      MFSC on 60 days' notice in writing to the shareholder in the event that
      the Fund ceases to assume the cost of these services. The Fund may
      terminate any SWP for an account if the value of the account falls below
      $5,000 as a result of share redemptions (other than as a result of a SWP)
      or an exchange of shares of the Fund for shares of another MFS Fund. Any
      SWP may be terminated at any time by either the shareholder or the Fund.

      INVEST BY MAIL -- Additional investments of $50 or more may be made at any
      time by mailing a check payable to the Fund directly to MFSC. The
      shareholder's account number and the name of his investment dealer must be
      included with each investment.


      GROUP PURCHASES -- A bona fide group and all its members may be treated at
      MFD's discretion as a single purchaser and, under the Right of
      Accumulation (but not the Letter of Intent) obtain quantity sales charge
      discounts on the purchase of Class A shares if the group (1) gives its
      endorsement or authorization to the investment program so it may be used
      by the investment dealer to facilitate solicitation of the membership,
      thus effecting economies of sales effort; (2) has been in existence for at
      least six months and has a legitimate purpose other than to purchase
      mutual fund shares at a discount; (3) is not a group of individuals whose
      sole organizational nexus is as credit cardholders of a company,
      policyholders of an insurance company, customers of a bank or
      broker-dealer, clients of an investment adviser or other similar groups;
      and (4) agrees to provide certification of membership of those members
      investing money in the MFS Funds upon the request of MFD.


      AUTOMATIC EXCHANGE PLAN -- Shareholders having account balances of at
      least $5,000 in any MFS Fund may participate in the Automatic Exchange
      Plan. The Automatic Exchange Plan provides for automatic exchanges of
      funds from the shareholder's account in an MFS Fund for investment in the
      same class of shares of other MFS Funds selected by the shareholder (if
      available for sale). Under the Automatic Exchange Plan, exchanges of at
      least $50 each may be made to up to six different funds effective on the
      seventh day of each month or of every third month, depending whether
      monthly or quarterly exchanges are elected by the shareholder. If the
      seventh day of the month is not a business day, the transaction will be
      processed on the next business day. Generally, the initial transfer will
      occur after receipt and processing by MFSC of an application in good
      order. Exchanges will continue to be made from a shareholder's account in
      any MFS Fund, as long as the balance of the account is sufficient to
      complete the exchanges. Additional payments made to a shareholder's
      account will extend the period that exchanges will continue to be made
      under the Automatic Exchange Plan. However, if additional payments are
      added to an account subject to the Automatic Exchange Plan shortly before
      an exchange is scheduled, such funds may not be available for exchanges
      until the following month; therefore, care should be used to avoid
      inadvertently terminating the Automatic Exchange Plan through exhaustion
      of the account balance.

         No transaction fee for exchanges will be charged in connection with the
      Automatic Exchange Plan. However, exchanges of shares of MFS Money Market
      Fund, MFS Government Money Market Fund and Class A shares of MFS Cash
      Reserve Fund will be subject to any applicable sales charge. Changes in
      amounts to be exchanged to the Fund, the funds to which exchanges are to
      be made and the timing of exchanges (monthly or quarterly), or termination
      of a shareholder's participation in the Automatic Exchange Plan will be
      made after instructions in writing or by telephone (an "Exchange Change
      Request") are received by MFSC in proper form (i.e., if in writing --
      signed by the record owner(s) exactly as shares are registered; if by
      telephone -- proper account identification is given by the dealer or
      shareholder of record). Each Exchange Change Request (other than
      termination of participation in the program) must involve at least $50.
      Generally, if an Exchange Change Request is received by telephone or in
      writing before the close of business on the last business day of a month,
      the Exchange Change Request will be effective for the following month's
      exchange.

         A shareholder's right to make additional investments in any of the MFS
      Funds, to make exchanges of shares from one MFS Fund to another and to
      withdraw from an MFS Fund, as well as a shareholder's other rights and
      privileges are not affected by a shareholder's participation in the
      Automatic Exchange Plan. The Automatic Exchange Plan is part of the
      Exchange Privilege. For additional information regarding the Automatic
      Exchange Plan, including the treatment of any CDSC, see "Exchange
      Privilege" below.

      REINSTATEMENT PRIVILEGE -- Shareholders of the Fund and shareholders of
      the other MFS Funds (except MFS Money Market Fund, MFS Government Money
      Market Fund and holders of Class A shares of MFS Cash Reserve Fund in the
      case where shares of such funds are acquired through direct purchase or
      reinvested dividends) who have redeemed their shares have a one-time right
      to reinvest the redemption proceeds in the same class of shares of any of
      the MFS Funds (if shares of the fund are available for sale) at net asset
      value (without a sales charge) and, if applicable, with credit for any
      CDSC paid. In the case of proceeds reinvested in MFS Money Market Fund,
      MFS Government Money Market Fund and Class A shares of MFS Cash Reserve
      Fund, the shareholder has the right to exchange the acquired shares for
      shares of another MFS Fund at net asset value pursuant to the exchange
      privilege described below. Such a reinvestment must be made within 90 days
      of the redemption and is limited to the amount of the redemption proceeds.
      If the shares credited for any CDSC paid are then redeemed within six
      years of the initial purchase in the case of Class B shares or 12 months
      of the initial purchase in the case of Class C shares and certain Class A
      shares, a CDSC will be imposed upon redemption. Although redemptions and
      repurchases of shares are taxable events, a reinvestment within a certain
      period of time in the same fund may be considered a "wash sale" and may
      result in the inability to recognize currently all or a portion of a loss
      realized on the original redemption for federal income tax purposes.
      Please see your tax adviser for further information.

      EXCHANGE PRIVILEGE
      Subject to the requirements set forth below, some or all of the shares of
      the same class in an account with the Fund for which payment has been
      received by the Fund (i.e., an established account) may be exchanged for
      shares of the same class of any of the other MFS Funds (if available for
      sale and if the purchaser is eligible to purchase the Class of shares) at
      net asset value. Exchanges will be made only after instructions in writing
      or by telephone (an "Exchange Request") are received for an established
      account by MFSC.

      EXCHANGES AMONG MFS FUNDS (excluding exchanges from MFS money market
      funds) -- No initial sales charge or CDSC will be imposed in connection
      with an exchange from shares of an MFS Fund to shares of any other MFS
      Fund, except with respect to exchanges from an MFS money market fund to
      another MFS Fund which is not an MFS money market fund (discussed below).
      With respect to an exchange involving shares subject to a CDSC, the CDSC
      will be unaffected by the exchange and the holding period for purposes of
      calculating the CDSC will carry over to the acquired shares.

      EXCHANGES FROM AN MFS MONEY MARKET FUND -- Special rules apply with
      respect to the imposition of an initial sales charge or a CDSC for
      exchanges from an MFS money market fund to another MFS Fund which is not
      an MFS money market fund. These rules are described under the caption "How
      to Purchase, Exchange and Redeem Shares" in the Prospectuses of those MFS
      money market funds.

      EXCHANGES INVOLVING THE MFS FIXED FUND -- Class A shares of any MFS Fund
      held by certain qualified retirement plans may be exchanged for units of
      participation of the MFS Fixed Fund (a bank collective investment fund)
      (the "Units"), and Units may be exchanged for Class A shares of any MFS
      Fund. With respect to exchanges between Class A shares subject to a CDSC
      and Units, the CDSC will carry over to the acquired shares or Units and
      will be deducted from the redemption proceeds when such shares or Units
      are subsequently redeemed, assuming the CDSC is then payable (the period
      during which the Class A shares and the Units were held will be aggregated
      for purposes of calculating the applicable CDSC). In the event that a
      shareholder initially purchases Units and then exchanges into Class A
      shares subject to an initial sales charge of an MFS Fund, the initial
      sales charge shall be due upon such exchange, but will not be imposed with
      respect to any subsequent exchanges between such Class A shares and Units
      with respect to shares on which the initial sales charge has already been
      paid. In the event that a shareholder initially purchases Units and then
      exchanges into Class A shares subject to a CDSC of an MFS Fund, the CDSC
      period will commence upon such exchange, and the applicability of the CDSC
      with respect to subsequent exchanges shall be governed by the rules set
      forth above in this paragraph.

      GENERAL -- Each Exchange Request must be in proper form (i.e., if in
      writing -- signed by the record owner(s) exactly as the shares are
      registered; if by telephone -- proper account identification is given by
      the dealer or shareholder of record), and each exchange must involve
      either shares having an aggregate value of at least $1,000 ($50 in the
      case of retirement plan participants whose sponsoring organizations
      subscribe to MFS FUNDamental 401(k) Plan or another similar 401(k)
      recordkeeping system made available by MFSC) or all the shares in the
      account. Each exchange involves the redemption of the shares of the Fund
      to be exchanged and the purchase of shares of the same class of the other
      MFS Fund. Any gain or loss on the redemption of the shares exchanged is
      reportable on the shareholder's federal income tax return, unless both the
      shares received and the shares surrendered in the exchange are held in a
      tax-deferred retirement plan or other tax-exempt account. No more than
      five exchanges may be made in any one Exchange Request by telephone. If
      the Exchange Request is received by MFSC prior to the close of regular
      trading on the Exchange the exchange usually will occur on that day if all
      the requirements set forth above have been complied with at that time.
      However, payment of the redemption proceeds by the Fund, and thus the
      purchase of shares of the other MFS Fund, may be delayed for up to seven
      days if the Fund determines that such a delay would be in the best
      interest of all its shareholders. Investment dealers which have satisfied
      criteria established by MFD may also communicate a shareholder's Exchange
      Request to MFD by facsimile subject to the requirements set forth above.

         Additional information with respect to any of the MFS Funds, including
      a copy of its current prospectus, may be obtained from investment dealers
      or MFSC. A shareholder considering an exchange should obtain and read the
      prospectus of the other fund and consider the differences in objectives
      and policies before making any exchange.

         Any state income tax advantages for investment in shares of each state-
      specific series of MFS Municipal Series Trust may only benefit residents
      of such states. Investors should consult with their own tax advisers to be
      sure this is an appropriate investment, based on their residency and each
      state's income tax laws. The exchange privilege (or any aspect of it) may
      be changed or discontinued and is subject to certain limitations imposed
      from time to time at the discretion of the Funds in order to protect the
      Funds.

      TAX-DEFERRED RETIREMENT PLANS
      Shares of the Fund may be purchased by all types of tax-deferred
      retirement plans. MFD makes available, through investment dealers, plans
      and/or custody agreements, the following:

      o  Traditional Individual Retirement Accounts (IRAs) (for individuals who
         desire to make limited contributions to a tax-deferred retirement
         program and, if eligible, to receive a federal income tax deduction for
         amounts contributed);

      o  Roth Individual Retirement Accounts (Roth IRAs) (for individuals who
         desire to make limited contributions to a tax-favored retirement
         program);

      o  Simplified Employee Pension (SEP-IRA) Plans;

      o  Retirement Plans Qualified under Section 401(k) of the Internal Revenue
         Code of 1986, as amended (the "Code");

      o  403(b) Plans (deferred compensation arrangements for employees of
         public school systems and certain non-profit organizations); and

      o  Certain other qualified pension and profit-sharing plans.

         The plan documents provided by MFD designate a trustee or custodian
      (unless another trustee or custodian is designated by the individual or
      group establishing the plan) and contain specific information about the
      plans. Each plan provides that dividends and distributions will be
      reinvested automatically. For further details with respect to any plan,
      including fees charged by the trustee, custodian or MFD, tax consequences
      and redemption information, see the specific documents for that plan. Plan
      documents other than those provided by MFD may be used to establish any of
      the plans described above. Third party administrative services, available
      for some corporate plans, may limit or delay the processing of
      transactions.

         An investor should consult with his tax adviser before establishing
      any of the tax-deferred retirement plans described above.

         Class C shares are not currently available for purchase by any
      retirement plan qualified under Internal Revenue Code Section 401(a) or
      403(b) if the retirement plan and/or the sponsoring organization subscribe
      to the MFS FUNDamental 401(k) Plan or another similar Section 401(a) or
      403(b) recordkeeping program made available by MFSC.

XI    DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES
      The Declaration of Trust permits the Trustees to issue an unlimited number
      of full and fractional Shares of Beneficial Interest (without par value)
      of one or more separate series and to divide or combine the shares of any
      series into a greater or lesser number of shares without thereby changing
      the proportionate beneficial interests in that series. The Declaration of
      Trust further authorizes the Trustees to classify or reclassify any series
      of shares into one or more classes. Each share of a class of the Fund
      represents an equal proportionate interest in the assets of the Fund
      allocable to that class. Upon liquidation of the Fund, shareholders of
      each class of the Fund are entitled to share pro rata in the Fund's net
      assets allocable to such class available for distribution to shareholders.
      The Trust reserves the right to create and issue a number of series and
      additional classes of shares, in which case the shares of each class of a
      series would participate equally in the earnings, dividends and assets
      allocable to that class of the particular series.

         Shareholders are entitled to one vote for each share held and may vote
      in the election of Trustees and on other matters submitted to meetings of
      shareholders. To the extent a shareholder of the Fund owns a controlling
      percentage of the Fund's shares, such shareholder may affect the outcome
      of such matters to a greater extent than other Fund shareholders. Although
      Trustees are not elected annually by the shareholders, the Declaration of
      Trust provides that a Trustee may be removed from office at a meeting of
      shareholders by a vote of two-thirds of the outstanding shares of the
      Trust. A meeting of shareholders will be called upon the request of
      shareholders of record holding in the aggregate not less than 10% of the
      outstanding voting securities of the Trust. No material amendment may be
      made to the Declaration of Trust without the affirmative vote of a
      majority of the Trust's outstanding shares (as defined in "Investment
      Restrictions" in Part I of this SAI). The Trust or any series of the Trust
      may be terminated (i) upon the merger or consolidation of the Trust or any
      series of the Trust with another organization or upon the sale of all or
      substantially all of its assets (or all or substantially all of the assets
      belonging to any series of the Trust), if approved by the vote of the
      holders of two-thirds of the Trust's or the affected series' outstanding
      shares voting as a single class, or of the affected series of the Trust,
      except that if the Trustees recommend such merger, consolidation or sale,
      the approval by vote of the holders of a majority of the Trust's or the
      affected series' outstanding shares will be sufficient, or (ii) upon
      liquidation and distribution of the assets of a Fund, if approved by the
      vote of the holders of two-thirds of its outstanding shares of the Trust,
      or (iii) by the Trustees by written notice to its shareholders. If not so
      terminated, the Trust will continue indefinitely.

         The Trust is an entity of the type commonly known as a "Massachusetts
      business trust." Under Massachusetts law, shareholders of such a trust
      may, under certain circumstances, be held personally liable as partners
      for its obligations. However, the Declaration of Trust contains an express
      disclaimer of shareholder liability for acts or obligations of the Trust
      and provides for indemnification and reimbursement of expenses out of
      Trust property for any shareholder held personally liable for the
      obligations of the Trust. The Declaration of Trust also provides that the
      Trust shall maintain appropriate insurance (for example, fidelity bonding
      and errors and omissions insurance) for the protection of the Trust and
      its shareholders and the Trustees, officers, employees and agents of the
      Trust covering possible tort and other liabilities. Thus, the risk of a
      shareholder incurring financial loss on account of shareholder liability
      is limited to circumstances in which both inadequate insurance existed and
      the Trust itself was unable to meet its obligations.

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

             redemption, the aggregate amount invested by the 401(a) or ESP Plan
             in shares of the MFS Funds (excluding the reinvestment of
             distributions) during the prior four years equals 50% or more of
             the total value of the 401(a) or ESP Plan's assets in the MFS

             recordkeeping or administration services agreement with MFD or one
             of its affiliates and (ii) the shares purchased or redeemed

    Shares transferred:
      o  To an IRA rollover account where any sales charges with respect to the
         shares being reregistered would have been waived had they been
         redeemed; and

      o  From a single account maintained for a 401(a) Plan to multiple accounts
         maintained by MFSC on behalf of individual participants of such Plan,

         Program or the MFS Recordkeeper Plus Program (but not the MFS
         Recordkeeper Program).

         >   Shares acquired by a retirement plan whose sponsoring organization
             subscribes to the MFS Participant Recordkeeping System where the
             purchase represents the immediate reinvestment of proceeds from the

    CIRCUMSTANCES:

             subscribe to the MFS Participant Recordkeeping System; and

         >   where the retirement plan and/or sponsoring organization
             demonstrates to the satisfaction of, and certifies to, MFSC that

  PART II - APPENDIX B
  --------------------

    DEALER COMMISSIONS AND CONCESSIONS
    This Appendix describes the various commissions paid and concessions made to
    dealers by MFD in connection with the sale of Fund shares. As used in this
    Appendix, the term "dealer" includes any broker, dealer, bank (including
    bank trust departments), registered investment adviser, financial planner
    and any other financial institutions having a selling agreement or other
    similar agreement with MFD.

    CLASS A SHARES
    Purchases Subject to an Initial Sales Charge. For purchases of Class A
    shares subject to an initial sales charge, MFD reallows a portion of the
    initial sales charge to dealers (which are alike for all dealers), as shown
    in Appendix D to Part I of this SAI. The difference between the total amount
    invested and the sum of (a) the net proceeds to the Fund and (b) the dealer
    reallowance, is the amount of the initial sales charge retained by MFD (as
    shown in Appendix D to Part I of this SAI). Because of rounding in the
    computation of offering price, the portion of the sales charge retained by
    MFD may vary and the total sales charge may be more or less than the sales
    charge calculated using the sales charge expressed as a percentage of the
    offering price or as a percentage of the net amount invested as listed in
    the Prospectus.

      Purchases Subject to a CDSC (but not an Initial Sales Charge). For
    purchases of Class A shares subject to a CDSC, MFD pays commissions to
    dealers on new investments made through such dealers as follows:

    COMMISSION
    PAID BY MFD
    TO DEALERS               CUMULATIVE PURCHASE AMOUNT
    ------------------------------------------------------

    1.00%                    On the first $2,000,000, plus
    0.80%                    Over $2,000,000 to $3,000,000, plus
    0.50%                    Over $3,000,000 to $50,000,000, plus
    0.25%                    Over $50,000,000


      Except for those employer sponsored retirement plans described below, for
    purposes of determining the level of commissions to be paid to dealers with
    respect to a shareholder's new investment in Class A shares purchases for
    each shareholder account (and certain other accounts for which the
    shareholder is a record or beneficial holder) will be aggregated over a
    12-month period (commencing from the date of the first such purchase).

      In the case of employer sponsored retirement plans whose account
    application or other account establishment paperwork is received in good
    order after December 31, 1999, purchases will be aggregated as described
    above but the cumulative purchase amount will not be re-set after the date
    of the first such purchase.

    CLASS B SHARES

    For purchases of Class B shares, MFD will pay commissions to dealers of
    3.75% of the purchase price of Class B shares purchased through dealers. MFD
    will also advance to dealers the first year service fee payable under the
    Fund's Distribution Plan at a rate equal to 0.25% of the purchase price of
    such shares. Therefore, the total amount paid to a dealer upon the sale of
    Class B shares is 4% of the purchase price of the shares (commission rate of
    3.75% plus a service fee equal to 0.25% of the purchase price).

      For purchases of Class B shares by a retirement plan whose sponsoring
    organization subscribes to the MFS Participant Recordkeeping System and
    which established its account with MFSC between July 1, 1996 and December
    31, 1998, MFD pays an amount to dealers equal to 3.00% of the amount
    purchased through such dealers (rather than the 4.00% payment described
    above), which is comprised of a commission of 2.75% plus the advancement of
    the first year service fee equal to 0.25% of the purchase price payable
    under the Fund's Distribution Plan.

      For purchases of Class B shares by a retirement plan whose sponsoring
    organization subscribes to the MFS Recordkeeper Plus product and which has
    established its account with MFSC on or after January 1, 1999 (provided that
    the plan establishment paperwork is received by MFSC in good order on or
    after November 15, 1998), MFD pays no up front commissions to dealers, but
    instead pays an amount to dealers equal to 1% per annum of the average daily
    net assets of the Fund attributable to plan assets, payable at the rate of
    0.25% at the end of each calendar quarter, in arrears. This commission
    structure is not available with respect to a plan with a pre-existing
    account(s) with any MFS Fund which seeks to switch to the MFS Recordkeeper
    Plus product.

    CLASS C SHARES
    For purchases of Class C shares, MFD will pay dealers 1.00% of the purchase
    price of Class C shares purchased through dealers and, as compensation
    therefor, MFD will retain the 1.00% per annum distribution and service fee
    paid under the Fund's Distribution Plan to MFD for the first year after
    purchase.

    ADDITIONAL DEALER COMMISSIONS/CONCESSIONS
    Dealers may receive different compensation with respect to sales of Class A,
    Class B and Class C shares. In addition, from time to time, MFD may pay
    dealers 100% of the applicable sales charge on sales of Class A shares of
    certain specified Funds sold by such dealer during a specified sales period.
    In addition, MFD or its affiliates may, from time to time, pay dealers an
    additional commission equal to 0.50% of the net asset value of all of the
    Class B and/or Class C shares of certain specified Funds sold by such dealer
    during a specified sales period. In addition, from time to time, MFD, at its
    expense, may provide additional commissions, compensation or promotional
    incentives ("concessions") to dealers which sell or arrange for the sale of
    shares of the Fund. Such concessions provided by MFD may include financial
    assistance to dealers in connection with preapproved conferences or
    seminars, sales or training programs for invited registered representatives
    and other employees, payment for travel expenses, including lodging,
    incurred by registered representatives and other employees for such seminars
    or training programs, seminars for the public, advertising and sales
    campaigns regarding one or more Funds, and/ or other dealer-sponsored
    events. From time to time, MFD may make expense reimbursements for special
    training of a dealer's registered representatives and other employees in
    group meetings or to help pay the expenses of sales contests. Other
    concessions may be offered to the extent not prohibited by state laws or any
    self-regulatory agency, such as the NASD.

    INVESTMENT TECHNIQUES, PRACTICES AND RISKS
    Set forth below is a description of investment techniques and practices
    which the MFS Funds may generally use in pursuing their investment
    objectives and principal investment policies, and the risks associated with
    these investment techniques and practices. The Fund will engage only in
    certain of these investment techniques and practices, as identified in
    Appendix A of the Fund's Prospectus. Investment practices and techniques
    that are not identified in Appendix A of the Fund's Prospectus do not apply
    to the Fund.

    INVESTMENT TECHNIQUES AND PRACTICES
    DEBT SECURITIES
    To the extent the Fund invests in the following types of debt securities,
    its net asset value may change as the general levels of interest rates
    fluctuate. When interest rates decline, the value of debt securities can be
    expected to rise. Conversely, when interest rates rise, the value of debt
    securities can be expected to decline. The Fund's investment in debt
    securities with longer terms to maturity are subject to greater volatility
    than the Fund's shorter-term obligations. Debt securities may have all types
    of interest rate payment and reset terms, including fixed rate, adjustable
    rate, zero coupon, contingent, deferred, payment in kind and auction rate
    features.

    ASSET-BACKED SECURITIES: The Fund may purchase the following types of
    asset-backed securities:

      COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTICLASS PASS-THROUGH
    SECURITIES: The Fund may invest a portion of its assets in collateralized
    mortgage obligations or "CMOs," which are debt obligations collateralized by
    mortgage loans or mortgage pass-through securities (such collateral referred
    to collectively as "Mortgage Assets"). Unless the context indicates
    otherwise, all references herein to CMOs include multiclass pass-through
    securities.

      Interest is paid or accrues on all classes of the CMOs on a monthly,
    quarterly or semi-annual basis. The principal of and interest on the
    Mortgage Assets may be allocated among the several classes of a CMO in
    innumerable ways. In a common structure, payments of principal, including
    any principal prepayments, on the Mortgage Assets are applied to the classes
    of a CMO in the order of their respective stated maturities or final
    distribution dates, so that no payment of principal will be made on any
    class of CMOs until all other classes having an earlier stated maturity or
    final distribution date have been paid in full. Certain CMOs may be stripped
    (securities which provide only the principal or interest factor of the
    underlying security). See "Stripped Mortgage-Backed Securities" below for a
    discussion of the risks of investing in these stripped securities and of
    investing in classes consisting of interest payments or principal payments.

      The Fund may also invest in parallel pay CMOs and Planned Amortization
    Class CMOs ("PAC Bonds"). Parallel pay CMOs are structured to provide
    payments of principal on each payment date to more than one class. These
    simultaneous payments are taken into account in calculating the stated
    maturity date or final distribution date of each class, which, as with other
    CMO structures, must be retired by its stated maturity date or final
    distribution date but may be retired earlier.

      CORPORATE ASSET-BACKED SECURITIES: The Fund may invest in corporate
    asset-backed securities. These securities, issued by trusts and special
    purpose corporations, are backed by a pool of assets, such as credit card
    and automobile loan receivables, representing the obligations of a number of
    different parties. These securities present certain risks. For instance, in
    the case of credit card receivables, these securities may not have the
    benefit of any security interest in the related collateral. Credit card
    receivables are generally unsecured and the debtors are entitled to the
    protection of a number of state and federal consumer credit laws, many of
    which give such debtors the right to set off certain amounts owed on the
    credit cards, thereby reducing the balance due. Most issuers of automobile
    receivables permit the servicers to retain possession of the underlying
    obligations. If the servicer were to sell these obligations to another
    party, there is a risk that the purchaser would acquire an interest superior
    to that of the holders of the related automobile receivables. In addition,
    because of the large number of vehicles involved in a typical issuance and
    technical requirements under state laws, the trustee for the holders of the
    automobile receivables may not have a proper security interest in all of the
    obligations backing such receivables. Therefore, there is the possibility
    that recoveries on repossessed collateral may not, in some cases, be
    available to support payments on these securities. The underlying assets
    (e.g., loans) are also subject to prepayments which shorten the securities'
    weighted average life and may lower their return.

      Corporate asset-backed securities are backed by a pool of assets
    representing the obligations of a number of different parties. To lessen the
    effect of failures by obligors on underlying assets to make payments, the
    securities may contain elements of credit support which fall into two
    categories: (i) liquidity protection and (ii) protection against losses
    resulting from ultimate default by an obligor on the underlying assets.
    Liquidity protection refers to the provision of advances, generally by the
    entity administering the pool of assets, to ensure that the receipt of
    payments on the underlying pool occurs in a timely fashion. Protection
    against losses resulting from ultimate default ensures payment through
    insurance policies or letters of credit obtained by the issuer or sponsor
    from third parties. The Fund will not pay any additional or separate fees
    for credit support. The degree of credit support provided for each issue is
    generally based on historical information respecting the level of credit
    risk associated with the underlying assets. Delinquency or loss in excess of
    that anticipated or failure of the credit support could adversely affect the
    return on an investment in such a security.

      MORTGAGE PASS-THROUGH SECURITIES: The Fund may invest in mortgage
    pass-through securities. Mortgage pass-through securities are securities
    representing interests in "pools" of mortgage loans. Monthly payments of
    interest and principal by the individual borrowers on mortgages are passed
    through to the holders of the securities (net of fees paid to the issuer or
    guarantor of the securities) as the mortgages in the underlying mortgage
    pools are paid off. The average lives of mortgage pass-throughs are variable
    when issued because their average lives depend on prepayment rates. The
    average life of these securities is likely to be substantially shorter than
    their stated final maturity as a result of unscheduled principal prepayment.
    Prepayments on underlying mortgages result in a loss of anticipated
    interest, and all or part of a premium if any has been paid, and the actual
    yield (or total return) to the Fund may be different than the quoted yield
    on the securities. Mortgage premiums generally increase with falling
    interest rates and decrease with rising interest rates. Like other fixed
    income securities, when interest rates rise the value of a mortgage
    pass-through security generally will decline; however, when interest rates
    are declining, the value of mortgage pass-through securities with prepayment
    features may not increase as much as that of other fixed-income securities.
    In the event of an increase in interest rates which results in a decline in
    mortgage prepayments, the anticipated maturity of mortgage pass-through
    securities held by the Fund may increase, effectively changing a security
    which was considered short or intermediate-term at the time of purchase into
    a long-term security. Long- term securities generally fluctuate more widely
    in response to changes in interest rates than short or intermediate-term
    securities.

      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 Government National Mortgage Association ("GNMA")); or
    guaranteed by agencies or instrumentalities of the U.S. Government (such as
    the Federal National Mortgage Association "FNMA") or the Federal Home Loan
    Mortgage Corporation, ("FHLMC") which are supported only by the
    discretionary authority of the U.S. Government to purchase the agency's
    obligations). Mortgage pass-through securities may also be issued by
    non-governmental issuers (such as commercial banks, savings and loan
    institutions, private mortgage insurance companies, mortgage bankers and
    other secondary market issuers). Some of these mortgage pass-through
    securities may be supported by various forms of insurance or guarantees.

      Interests in pools of mortgage-related securities differ from other forms
    of debt securities, 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 mortgage loans, net of any fees paid to the issuer or guarantor of
    such securities. Additional payments are caused by prepayments of principal
    resulting from the sale, refinancing or foreclosure of the underlying
    property, net of fees or costs which may be incurred. Some mortgage
    pass-through securities (such as securities issued by the GNMA) are
    described as "modified pass-through." These securities entitle the holder to
    receive all interests and principal payments owed on the mortgages in the
    mortgage pool, net of certain fees, at the scheduled payment dates
    regardless of whether the mortgagor actually makes the payment.

      The principal governmental guarantor of mortgage pass-through securities
    is 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 Federal Housing Administration
    ("FHA") insured or Veterans Administration ("VA") guaranteed mortgages.
    These guarantees, however, do not apply to the market value or yield of
    mortgage pass-through securities. GNMA securities are often purchased at a
    premium over the maturity value of the underlying mortgages. This premium is
    not guaranteed and will be lost if prepayment occurs.

      Government-related guarantors (i.e., whose guarantees are not backed by
    the full faith and credit of the U.S. Government) include FNMA and 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 residential
    mortgages (i.e., mortgages not insured or guaranteed by any governmental
    agency) from a list of approved seller/servicers which include state and
    federally chartered savings and loan associations, mutual savings banks,
    commercial banks, credit unions and mortgage bankers. Pass-through
    securities issued by FNMA are guaranteed as to timely payment by FNMA of
    principal and interest.

      FHLMC is also a government-sponsored corporation owned by private
    stockholders. FHLMC issues Participation Certificates ("PCs") which
    represent interests in conventional mortgages (i.e., not federally insured
    or guaranteed) for FHLMC's national portfolio. FHLMC guarantees timely
    payment of interest and ultimate collection of principal regardless of the
    status of the underlying mortgage loans.

      Commercial banks, savings and loan institutions, private mortgage
    insurance companies, mortgage bankers and other secondary market issuers
    also create pass through pools of mortgage loans. Such issuers may also be
    the originators and/or servicers of the underlying 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 the former pools. However, timely payment of interest and principal of
    mortgage loans in 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. The Fund
    may also buy mortgage-related securities without insurance or guarantees.

      STRIPPED MORTGAGE-BACKED SECURITIES: The Fund may invest a portion of its
    assets in stripped mortgage-backed securities ("SMBS") which are derivative
    multiclass mortgage 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 institutions, mortgage banks, commercial
    banks and investment banks.

      SMBS are usually structured with two classes that receive different
    proportions of the interest and principal distributions from a pool of
    mortgage assets. A common type of SMBS will have one class receiving some of
    the interest and most of the principal from the Mortgage Assets, while the
    other class will receive most of the interest and the remainder of the
    principal. In the most extreme case, one class will receive all of the
    interest (the interest-only or "I0" class) while the other class will
    receive all of the principal (the principal-only or "P0" class). The yield
    to maturity on an I0 is extremely sensitive to the rate of principal
    payments, including prepayments on the related underlying Mortgage Assets,
    and a rapid rate of principal payments may have a material adverse effect on
    such security's yield to maturity. If the underlying Mortgage Assets
    experience greater than anticipated prepayments of principal, the Fund may
    fail to fully recoup its initial investment in these securities. The market
    value of the class consisting primarily or entirely of principal payments
    generally is unusually volatile in response to changes in interest rates.
    Because SMBS were only recently introduced, established trading markets for
    these securities have not yet developed, although the securities are traded
    among institutional investors and investment banking firms.

      CORPORATE SECURITIES: The Fund may invest in debt securities, such as
    convertible and non-convertible bonds, notes and debentures, issued by
    corporations, limited partnerships and other similar entities.

      LOANS AND OTHER DIRECT INDEBTEDNESS: The Fund may purchase loans and other
    direct indebtedness. In purchasing a loan, the Fund acquires some or all of
    the interest of a bank or other lending institution in a loan to a
    corporate, governmental or other borrower. Many such loans are secured,
    although some may be unsecured. Such loans may be in default at the time of
    purchase. Loans that are fully secured offer the Fund more protection than
    an unsecured loan in the event of non-payment of scheduled interest or
    principal. However, there is no assurance that the liquidation of collateral
    from a secured loan would satisfy the corporate borrowers obligation, or
    that the collateral can be liquidated.

      These loans are made generally to finance internal growth, mergers,
    acquisitions, stock repurchases, leveraged buy-outs and other corporate
    activities. Such loans are typically made by a syndicate of lending
    institutions, represented by an agent lending institution which has
    negotiated and structured the loan and is responsible for collecting
    interest, principal and other amounts due on its own behalf and on behalf of
    the others in the syndicate, and for enforcing its and their other rights
    against the borrower. Alternatively, such loans may be structured as a
    novation, pursuant to which the Fund would assume all of the rights of the
    lending institution in a loan or as an assignment, pursuant to which the
    Fund would purchase an assignment of a portion of a lenders interest in a
    loan either directly from the lender or through an intermediary. The Fund
    may also purchase trade or other claims against companies, which generally
    represent money owned by the company to a supplier of goods or services.
    These claims may also be purchased at a time when the company is in default.

      Certain of the loans and the other direct indebtedness acquired by the
    Fund may involve revolving credit facilities or other standby financing
    commitments which obligate the Fund to pay additional cash on a certain date
    or on demand. These commitments may have the effect of requiring the Fund to
    increase its investment in a company at a time when the Fund might not
    otherwise decide to do so (including at 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
    hold and maintain in a segregated account cash or other high grade debt
    obligations in an amount sufficient to meet such commitments.

      The Fund's ability to receive payment of principal, interest and other
    amounts due in connection with these investments will depend primarily on
    the financial condition of the borrower. In selecting the loans and other
    direct indebtedness which the Fund will purchase, the Adviser will rely upon
    its own (and not the original lending institution's) credit analysis of the
    borrower. As the Fund may be required to rely upon another lending
    institution to collect and pass onto the Fund amounts payable with respect
    to the loan and to enforce the Fund's rights under the loan and other direct
    indebtedness, an insolvency, bankruptcy or reorganization of the lending
    institution may delay or prevent the Fund from receiving such amounts. In
    such cases, the Fund will evaluate as well the creditworthiness of the
    lending institution and will treat both the borrower and the lending
    institution as an "issuer" of the loan for purposes of certain investment
    restrictions pertaining to the diversification of the Fund's portfolio
    investments. The highly leveraged nature of many such loans and other direct
    indebtedness may make such loans and other direct indebtedness especially
    vulnerable to adverse changes in economic or market conditions. Investments
    in such loans and other direct indebtedness may involve additional risk to
    the Fund.

      LOWER RATED BONDS: The Fund may invest in fixed income securities rated Ba
    or lower by Moody's or BB or lower by S&P, Fitch or Duff & Phelps and
    comparable unrated securities (commonly known as "junk bonds"). See Appendix
    D for a description of bond ratings. No minimum rating standard is required
    by the Fund. These securities are considered speculative and, while
    generally providing greater income than investments in higher rated
    securities, will involve greater risk of principal and income (including the
    possibility of default or bankruptcy of the issuers of such securities) and
    may involve greater volatility of price (especially during periods of
    economic uncertainty or change) than securities in the higher rating
    categories and because yields vary over time, no specific level of income
    can ever be assured. These lower rated high yielding fixed income securities
    generally tend to reflect economic changes (and the outlook for economic
    growth), short-term corporate and industry developments and the market's
    perception of their credit quality (especially during times of adverse
    publicity) to a greater extent than higher rated securities which react
    primarily to fluctuations in the general level of interest rates (although
    these lower rated fixed income securities are also affected by changes in
    interest rates). In the past, economic downturns or an increase in interest
    rates have, under certain circumstances, caused a higher incidence of
    default by the issuers of these securities and may do so in the future,
    especially in the case of highly leveraged issuers. The prices for these
    securities may be affected by legislative and regulatory developments. The
    market for these lower rated fixed income securities may be less liquid than
    the market for investment grade fixed income securities. Furthermore, the
    liquidity of these lower rated securities may be affected by the market's
    perception of their credit quality. Therefore, the Adviser's judgment may at
    times play a greater role in valuing these securities than in the case of
    investment grade fixed income securities, and it also may be more difficult
    during times of certain adverse market conditions to sell these lower rated
    securities to meet redemption requests or to respond to changes in the
    market.

      While the Adviser may refer to ratings issued by established credit rating
    agencies, it is not the Fund's policy to rely exclusively on ratings issued
    by these rating agencies, but rather to supplement such ratings with the
    Adviser's own independent and ongoing review of credit quality. To the
    extent a Fund invests in these lower rated securities, the achievement of
    its investment objectives may be a more dependent on the Adviser's own
    credit analysis than in the case of a fund investing in higher quality fixed
    income securities. These lower rated securities may also include zero coupon
    bonds, deferred interest bonds and PIK bonds.

      MUNICIPAL BONDS: The Fund may invest in debt securities issued by or on
    behalf of states, territories and possessions of the United States and the
    District of Columbia and their political subdivisions, agencies or
    instrumentalities, the interest on which is exempt from federal income tax
    ("Municipal Bonds"). Municipal Bonds include debt securities which pay
    interest income that is subject to the alternative minimum tax. The Fund may
    invest in Municipal Bonds whose issuers pay interest on the Bonds from
    revenues from projects such as multifamily housing, nursing homes, electric
    utility systems, hospitals or life care facilities.

      If a revenue bond is secured by payments generated from a project, and the
    revenue bond is also secured by a lien on the real estate comprising the
    project, foreclosure by the indenture trustee on the lien for the benefit of
    the bondholders creates additional risks associated with owning real estate,
    including environmental risks.

      Housing revenue bonds typically are issued by a state, county or local
    housing authority and are secured only by the revenues of mortgages
    originated by the authority using the proceeds of the bond issue. Because of
    the impossibility of precisely predicting demand for mortgages from the
    proceeds of such an issue, there is a risk that the proceeds of the issue
    will be in excess of demand, which would result in early retirement of the
    bonds by the issuer. Moreover, such housing revenue bonds depend for their
    repayment upon the cash flow from the underlying mortgages, which cannot be
    precisely predicted when the bonds are issued. Any difference in the actual
    cash flow from such mortgages from the assumed cash flow could have an
    adverse impact upon the ability of the issuer to make scheduled payments of
    principal and interest on the bonds, or could result in early retirement of
    the bonds. Additionally, such bonds depend in part for scheduled payments of
    principal and interest upon reserve funds established from the proceeds of
    the bonds, assuming certain rates of return on investment of such reserve
    funds. If the assumed rates of return are not realized because of changes in
    interest rate levels or for other reasons, the actual cash flow for
    scheduled payments of principal and interest on the bonds may be inadequate.
    The financing of multi-family housing projects is affected by a variety of
    factors, including satisfactory completion of construction within cost
    constraints, the achievement and maintenance of a sufficient level of
    occupancy, sound management of the developments, timely and adequate
    increases in rents to cover increases in operating expenses, including
    taxes, utility rates and maintenance costs, changes in applicable laws and
    governmental regulations and social and economic trends.

      Electric utilities face problems in financing large construction programs
    in inflationary periods, cost increases and delay occasioned by
    environmental considerations (particularly with respect to nuclear
    facilities), difficulty in obtaining fuel at reasonable prices, the cost of
    competing fuel sources, difficulty in obtaining sufficient rate increases
    and other regulatory problems, the effect of energy conservation and
    difficulty of the capital market to absorb utility debt.

      Health care facilities include life care facilities, nursing homes and
    hospitals. Life care facilities are alternative forms of long-term housing
    for the elderly which offer residents the independence of condominium life
    style and, if needed, the comprehensive care of nursing home services. Bonds
    to finance these facilities have been issued by various state industrial
    development authorities. Since the bonds are secured only by the revenues of
    each facility and not by state or local government tax payments, they are
    subject to a wide variety of risks. Primarily, the projects must maintain
    adequate occupancy levels to be able to provide revenues adequate to
    maintain debt service payments. Moreover, in the case of life care
    facilities, since a portion of housing, medical care and other services may
    be financed by an initial deposit, there may be risk if the facility does
    not maintain adequate financial reserves to secure estimated actuarial
    liabilities. The ability of management to accurately forecast inflationary
    cost pressures weighs importantly in this process. The facilities may also
    be affected by regulatory cost restrictions applied to health care delivery
    in general, particularly state regulations or changes in Medicare and
    Medicaid payments or qualifications, or restrictions imposed by medical
    insurance companies. They may also face competition from alternative health
    care or conventional housing facilities in the private or public sector.
    Hospital bond ratings are often based on feasibility studies which contain
    projections of expenses, revenues and occupancy levels. A hospital's gross
    receipts and net income available to service its debt are influenced by
    demand for hospital services, the ability of the hospital to provide the
    services required, management capabilities, economic developments in the
    service area, efforts by insurers and government agencies to limit rates and
    expenses, confidence in the hospital, service area economic developments,
    competition, availability and expense of malpractice insurance, Medicaid and
    Medicare funding, and possible federal legislation limiting the rates of
    increase of hospital charges.

      The Fund may invest in municipal lease securities. These are undivided
    interests in a portion of an obligation in the from of a lease or
    installment purchase which is issued by state and local governments to
    acquire equipment and facilities. Municipal leases frequently have special
    risks not normally associated with general obligation or revenue bonds.
    Leases and installment purchase or conditional sale contracts (which
    normally provide for title to the leased asset to pass eventually to the
    governmental issuer) have evolved as a means for governmental issuers to
    acquire property and equipment without meeting the constitutional and
    statutory requirements for the issuance of debt. The debt-issuance
    limitations are deemed to be inapplicable because of the inclusion in many
    leases or contracts of "non-appropriation" clauses that provide that the
    governmental issuer has no obligation to make future payments under the
    lease or contract unless money is appropriated for such purpose by the
    appropriate legislative body on a yearly or other periodic basis. Although
    the obligations will be secured by the leased equipment or facilities, the
    disposition of the property in the event of non-appropriation or foreclosure
    might, in some cases, prove difficult. There are, of course, variations in
    the security of municipal lease securities, both within a particular
    classification and between classifications, depending on numerous factors.

      The Fund may also invest in bonds for industrial and other projects, such
    as sewage or solid waste disposal or hazardous waste treatment facilities.
    Financing for such projects will be subject to inflation and other general
    economic factors as well as construction risks including labor problems,
    difficulties with construction sites and the ability of contractors to meet
    specifications in a timely manner. Because some of the materials, processes
    and wastes involved in these projects may include hazardous components,
    there are risks associated with their production, handling and disposal.

      SPECULATIVE BONDS: The Fund may invest in fixed income and convertible
    securities rated Baa by Moody's or BBB by S&P, Fitch or Duff & Phelps and
    comparable unrated securities. See Appendix D for a description of bond
    ratings. These securities, while normally exhibiting adequate protection
    parameters, have speculative characteristics and changes in economic
    conditions or other circumstances are more likely to lead to a weakened
    capacity to make principal and interest payments than in the case of higher
    grade securities.

      U.S. GOVERNMENT SECURITIES: The Fund may invest in U.S. Government
    Securities including (i) U.S. Treasury obligations, all of which are backed
    by the full faith and credit of the U.S. Government and (ii) U.S. Government
    Securities, some of which are backed by the full faith and credit of the
    U.S. Treasury, e.g., direct pass-through certificates of the GNMA; some of
    which are backed only by the credit of the issuer itself, e.g., obligations
    of the Student Loan Marketing Association; and some of which are supported
    by the discretionary authority of the U.S. Government to purchase the
    agency's obligations, e.g., obligations of the FNMA.

      U.S. Government Securities also include interests in trust or other
    entities representing interests in obligations that are issued or
    guaranteed by the U.S. Government, its agencies, authorities or
    instrumentalities.

      VARIABLE AND FLOATING RATE OBLIGATIONS: The Fund may invest in floating or
    variable rate securities. Investments in floating or variable rate
    securities normally will involve industrial development or revenue bonds
    which provide that the rate of interest is set as a specific percentage of a
    designated base rate, such as rates on Treasury Bonds or Bills or the prime
    rate at a major commercial bank, and that a bondholder can demand payment of
    the obligations on behalf of the Fund on short notice at par plus accrued
    interest, which amount may be more or less than the amount the bondholder
    paid for them. The maturity of floating or variable rate obligations
    (including participation interests therein) is deemed to be the longer of
    (i) the notice period required before the Fund is entitled to receive
    payment of the obligation upon demand or (ii) the period remaining until the
    obligation's next interest rate adjustment. If not redeemed by the Fund
    through the demand feature, the obligations mature on a specified date which
    may range up to thirty years from the date of issuance.

      ZERO COUPON BONDS, DEFERRED INTEREST BONDS AND PIK BONDS: The Fund may
    invest in zero coupon bonds, deferred interest bonds and bonds on which the
    interest is payable in kind ("PIK bonds"). Zero coupon and deferred interest
    bonds are debt obligations which are issued at a significant discount from
    face value. The discount approximates the total amount of interest the bonds
    will accrue and compound over the period until maturity or the first
    interest payment date at a rate of interest reflecting the market rate of
    the security at the time of issuance. While zero coupon bonds do not require
    the periodic payment of interest, deferred interest bonds provide for a
    period of delay before the regular payment of interest begins. PIK bonds are
    debt obligations which provide that the issuer may, at its option, pay
    interest on such bonds in cash or in the form of additional debt
    obligations. Such investments benefit the issuer by mitigating its need for
    cash to meet debt service, but also require a higher rate of return to
    attract investors who are willing to defer receipt of such cash. Such
    investments may experience greater volatility in market value than debt
    obligations which make regular payments of interest. The Fund will accrue
    income on such investments for tax and accounting purposes, which is
    distributable to shareholders and which, because no cash is received at the
    time of accrual, may require the liquidation of other portfolio securities
    to satisfy the Fund's distribution obligations.

    EQUITY SECURITIES
    The Fund may invest in all types of equity securities, including the
    following: common stocks, preferred stocks and preference stocks; securities
    such as bonds, warrants or rights that are convertible into stocks; and
    depositary receipts for those securities. These securities may be listed on
    securities exchanges, traded in various over-the-counter markets or have no
    organized market.

    FOREIGN SECURITIES EXPOSURE
    The Fund may invest in various types of foreign securities, or securities
    which provide the Fund with exposure to foreign securities or foreign
    currencies, as discussed below:

    BRADY BONDS: The Fund may invest in Brady Bonds, which are securities
    created through the exchange of existing commercial bank loans to public and
    private entities in certain emerging markets for new bonds in 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 to date in Argentina,
    Brazil, Bulgaria, Costa Rica, Croatia, Dominican Republic, Ecuador, Jordan,
    Mexico, Morocco, Nigeria, Panama, Peru, the Philippines, Poland, Slovenia,
    Uruguay and Venezuela. Brady Bonds have been issued only recently, and for
    that reason do not have a long payment history. Brady Bonds may be
    collateralized or uncollateralized, are issued in various currencies (but
    primarily the U.S. dollar) and are actively traded in over-the-counter
    secondary markets. U.S. dollar-denominated, collateralized Brady Bonds,
    which may be fixed rate bonds or floating-rate bonds, are generally
    collateralized in full as to principal by U.S. Treasury zero coupon bonds
    having the same maturity as the bonds. Brady Bonds are often viewed as
    having three or four valuation components: the collateralized repayment of
    principal at final maturity; the collateralized interest payments; the
    uncollateralized interest payments; and any uncollateralized repayment of
    principal at maturity (these uncollateralized amounts constituting the
    "residual risk"). In light of the residual risk of Brady Bonds and the
    history of defaults of countries issuing Brady Bonds with respect to
    commercial bank loans by public and private entities, investments in Brady
    Bonds may be viewed as speculative.

    DEPOSITARY RECEIPTS: The Fund may invest in American Depositary Receipts
    ("ADRs"), Global Depositary Receipts ("GDRs") and other types of depositary
    receipts. ADRs are certificates by a U.S. depositary (usually a bank) and
    represent a specified quantity of shares of an underlying non- U.S. stock on
    deposit with a custodian bank as collateral. GDRs and other types of
    depositary receipts are typically issued by foreign banks or trust companies
    and evidence ownership of underlying securities issued by either a foreign
    or a U.S. company. Generally, ADRs are in registered form and are designed
    for use in U.S. securities markets and GDRs are in bearer form and are
    designed for use in foreign securities markets. For the purposes of the
    Fund's policy to invest a certain percentage of its assets in foreign
    securities, the investments of the Fund in ADRs, GDRs and other types of
    depositary receipts are deemed to be investments in the underlying
    securities.

      ADRs may be sponsored or unsponsored. A sponsored ADR is issued by a
    depositary which has an exclusive relationship with the issuer of the
    underlying security. An unsponsored ADR may be issued by any number of U.S.
    depositories. Under the terms of most sponsored arrangements, depositories
    agree to distribute notices of shareholder meetings and voting instructions,
    and to provide shareholder communications and other information to the ADR
    holders at the request of the issuer of the deposited securities. The
    depository of an unsponsored ADR, on the other hand, is under no obligation
    to distribute shareholder communications received from the issuer of the
    deposited securities or to pass through voting rights to ADR holders in
    respect of the deposited securities. The Fund may invest in either type of
    ADR. Although the U.S. investor holds a substitute receipt of ownership
    rather than direct stock certificates, the use of the depositary receipts in
    the United States can reduce costs and delays as well as potential currency
    exchange and other difficulties. The Fund may purchase securities in local
    markets and direct delivery of these ordinary shares to the local depositary
    of an ADR agent bank in foreign country. Simultaneously, the ADR agents
    create a certificate which settles at the Fund's custodian in five days. The
    Fund may also execute trades on the U.S. markets using existing ADRs. A
    foreign issuer of the security underlying an ADR is generally not subject to
    the same reporting requirements in the United States as a domestic issuer.
    Accordingly, information available to a U.S. investor will be limited to the
    information the foreign issuer is required to disclose in its country and
    the market value of an ADR may not reflect undisclosed material information
    concerning the issuer of the underlying security. ADRs may also be subject
    to exchange rate risks if the underlying foreign securities are denominated
    in a foreign currency.

    DOLLAR-DENOMINATED FOREIGN DEBT SECURITIES: The Fund may invest in
    dollar-denominated foreign debt securities. Investing in dollar-denominated
    foreign debt represents a greater degree of risk than investing in domestic
    securities, due to less publicly available information, less securities
    regulation, war or expropriation. Special considerations may include higher
    brokerage costs and thinner trading markets. Investments in foreign
    countries could be affected by other factors including extended settlement
    periods.


    EMERGING MARKETS: The Fund may invest in securities of government,
    government-related, supranational and corporate issuers located in emerging
    markets. Emerging markets include any country determined by the Adviser to
    have an emerging market economy, taking into account a number of factors,
    including whether the country has a low- to middle-income economy according
    to the International Bank for Reconstruction and Development, the country's
    foreign currency debt rating, its political and economic stability and the
    development of its financial and capital markets. The Adviser determines
    whether an issuer's principal activities are located in an emerging market
    country by considering such factors as its country of organization, the
    principal trading market for securities, the source of its revenues and the
    location of its assets. Such investments entail significant risks as
    described below.


    o  Company Debt -- Governments of many emerging market countries have
       exercised and continue to exercise substantial influence over many
       aspects of the private sector through the ownership or control of many
       companies, including some of the largest in any given country. As a
       result, government actions in the future could have a significant effect
       on economic conditions in emerging markets, which in turn, may adversely
       affect companies in the private sector, general market conditions and
       prices and yields of certain of the securities in the Fund's portfolio.
       Expropriation, confiscatory taxation, nationalization, political,
       economic or social instability or other similar developments have
       occurred frequently over the history of certain emerging markets and
       could adversely affect the Fund's assets should these conditions recur.

    o  Default; Legal Recourse -- The Fund may have limited legal recourse in
       the event of a default with respect to certain debt obligations it may
       hold. If the issuer of a fixed income security owned by the Fund
       defaults, the Fund may incur additional expenses to seek recovery. Debt
       obligations issued by emerging market governments differ from debt
       obligations of private entities; remedies from defaults on debt
       obligations issued by emerging market governments, unlike those on
       private debt, must be pursued in the courts of the defaulting party
       itself. The Fund's ability to enforce its rights against private issuers
       may be limited. The ability to attach assets to enforce a judgment may be
       limited. Legal recourse is therefore somewhat diminished. Bankruptcy,
       moratorium and other similar laws applicable to private issuers of debt
       obligations may be substantially different from those of other countries.
       The political context, expressed as an emerging market governmental
       issuer's willingness to meet the terms of the debt obligation, for
       example, is of considerable importance. In addition, no assurance can be
       given that the holders of commercial bank debt may not contest payments
       to the holders of debt obligations in the event of default under
       commercial bank loan agreements.

    o  Foreign Currencies -- The securities in which the Fund invests may be
       denominated in foreign currencies and international currency units and
       the Fund may invest a portion of its assets directly in foreign
       currencies. Accordingly, the weakening of these currencies and units
       against the U.S. dollar may result in a decline in the Fund's asset
       value.

       Some emerging market countries also may have managed currencies, which
       are not free floating against the U.S. dollar. In addition, there is risk
       that certain emerging market countries may restrict the free conversion
       of their currencies into other currencies. Further, certain emerging
       market currencies may not be internationally traded. Certain of these
       currencies have experienced a steep devaluation relative to the U.S.
       dollar. Any devaluations in the currencies in which a Fund's portfolio
       securities are denominated may have a detrimental impact on the Fund's
       net asset value.

    o  Inflation -- Many emerging markets have experienced substantial, and in
       some periods extremely high, rates of inflation for many years. Inflation
       and rapid fluctuations in inflation rates have had and may continue to
       have adverse effects on the economies and securities markets of certain
       emerging market countries. In an attempt to control inflation, wage and
       price controls have been imposed in certain countries. Of these
       countries, some, in recent years, have begun to control inflation through
       prudent economic policies.

    o  Liquidity; Trading Volume; Regulatory Oversight -- The securities markets
       of emerging market countries are substantially smaller, less developed,
       less liquid and more volatile than the major securities markets in the
       U.S. Disclosure and regulatory standards are in many respects less
       stringent than U.S. standards. Furthermore, there is a lower level of
       monitoring and regulation of the markets and the activities of investors
       in such markets.

       The limited size of many emerging market securities markets and limited
       trading volume in the securities of emerging market issuers compared to
       volume of trading in the securities of U.S. issuers could cause prices to
       be erratic for reasons apart from factors that affect the soundness and
       competitiveness of the securities issuers. For example, limited market
       size may cause prices to be unduly influenced by traders who control
       large positions. Adverse publicity and investors' perceptions, whether or
       not based on in-depth fundamental analysis, may decrease the value and
       liquidity of portfolio securities.

       The risk also exists that an emergency situation may arise in one or more
       emerging markets, as a result of which trading of securities may cease or
       may be substantially curtailed and prices for the Fund's securities in
       such markets may not be readily available. The Fund may suspend
       redemption of its shares for any period during which an emergency exists,
       as determined by the Securities and Exchange Commission (the "SEC").
       Accordingly, if the Fund believes that appropriate circumstances exist,
       it will promptly apply to the SEC for a determination that an emergency
       is present. During the period commencing from the Fund's identification
       of such condition until the date of the SEC action, the Fund's securities
       in the affected markets will be valued at fair value determined in good
       faith by or under the direction of the Board of Trustees.

    o  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 such 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 towards the International Monetary Fund and
       the political constraints to which a governmental entity may be subject.
       Governmental entities may also be dependent on expected disbursements
       from foreign governments, multilateral agencies and others abroad to
       reduce principal and interest 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 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 proceedings by which
       sovereign debt on which governmental entities have defaulted may be
       collected in whole or in part.

       Emerging market governmental issuers are among the largest debtors to
       commercial banks, foreign governments, international financial
       organizations and other financial institutions. Certain emerging market
       governmental issuers have not been able to make payments of interest on
       or principal of debt obligations as those payments have come due.
       Obligations arising from past restructuring agreements may affect the
       economic performance and political and social stability of those issuers.

       The ability of emerging market governmental issuers to make timely
       payments on their obligations is likely to be influenced strongly by the
       issuer's balance of payments, including export performance, and its
       access to international credits and investments. An emerging market whose
       exports are concentrated in a few commodities could be vulnerable to a
       decline in the international prices of one or more of those commodities.
       Increased protectionism on the part of an emerging market's trading
       partners could also adversely affect the country's exports and tarnish
       its trade account surplus, if any. To the extent that emerging markets
       receive payment for their exports in currencies other than dollars or
       non-emerging market currencies, its ability to make debt payments
       denominated in dollars or non-emerging market currencies could be
       affected.

       To the extent that an emerging market country cannot generate a trade
       surplus, it must depend on continuing loans from foreign governments,
       multilateral organizations or private commercial banks, aid payments from
       foreign governments and on inflows of foreign investment. The access of
       emerging markets to these forms of external funding may not be certain,
       and a withdrawal of external funding could adversely affect the capacity
       of emerging market country governmental issuers to make payments on their
       obligations. In addition, the cost of servicing emerging market debt
       obligations can be affected by a change in international interest rates
       since the majority of these obligations carry interest rates that are
       adjusted periodically based upon international rates.

       Another factor bearing on the ability of emerging market countries to
       repay debt obligations is the level of international reserves of the
       country. Fluctuations in the level of these reserves affect the amount of
       foreign exchange readily available for external debt payments and thus
       could have a bearing on the capacity of emerging market countries to make
       payments on these debt obligations.

    o  Withholding -- Income from securities held by the Fund could be reduced
       by a withholding tax on the source or other taxes imposed by the emerging
       market countries in which the Fund makes its investments. The Fund's net
       asset value may also be affected by changes in the rates or methods of
       taxation applicable to the Fund or to entities in which the Fund has
       invested. The Adviser will consider the cost of any taxes in determining
       whether to acquire any particular investments, but can provide no
       assurance that the taxes will not be subject to change.


    FOREIGN SECURITIES: The Fund may invest in dollar-denominated and non
    dollar-denominated foreign securities. The issuer's principal activities
    generally are deemed to be located in a particular country if: (a) the
    security is issued or guaranteed by the government of that country or any of
    its agencies, authorities or instrumentalities; (b) the issuer is organized
    under the laws of, and maintains a principal office in, that country; (c)
    the issuer has its principal securities trading market in that country; (d)
    the issuer derives 50% or more of its total revenues from goods sold or
    services performed in that country; or (e) the issuer has 50% or more of its
    assets in that country.

      Investing in securities of foreign issuers generally involves risks not
    ordinarily associated with investing in securities of domestic issuers.
    These include changes in currency rates, exchange control regulations,
    securities settlement practices, governmental administration or economic or
    monetary policy (in the United States or abroad) or circumstances in
    dealings between nations. Costs may be incurred in connection with
    conversions between various currencies. Special considerations may also
    include more limited information about foreign issuers, higher brokerage
    costs, different accounting standards and thinner trading markets. Foreign
    securities markets may also be less liquid, more volatile and less subject
    to government supervision than in the United States. Investments in foreign
    countries could be affected by other factors including expropriation,
    confiscatory taxation and potential difficulties in enforcing contractual
    obligations and could be subject to extended settlement periods. As a result
    of its investments in foreign securities, the Fund may receive interest or
    dividend payments, or the proceeds of the sale or redemption of such
    securities, in the foreign currencies in which such securities are
    denominated. Under certain circumstances, such as where the Adviser believes
    that the applicable exchange rate is unfavorable at the time the currencies
    are received or the Adviser anticipates, for any other reason, that the
    exchange rate will improve, the Fund may hold such currencies for an
    indefinite period of time. While the holding of currencies will permit the
    Fund to take advantage of favorable movements in the applicable exchange
    rate, such strategy also exposes the Fund to risk of loss if exchange rates
    move in a direction adverse to the Fund's position. Such losses could reduce
    any profits or increase any losses sustained by the Fund from the sale or
    redemption of securities and could reduce the dollar value of interest or
    dividend payments received. The Fund's investments in foreign securities may
    also include "privatizations." Privatizations are situations where the
    government in a given country, including emerging market countries, sells
    part or all of its stakes in government owned or controlled enterprises. In
    certain countries, the ability of foreign entities to participate in
    privatizations may be limited by local law and the terms on which the
    foreign entities may be permitted to participate may be less advantageous
    than those afforded local investors.


    FORWARD CONTRACTS
    The Fund may enter into contracts for the purchase or sale of a specific
    currency at a future date at a price set at the time the contract is entered
    into (a "Forward Contract"), for hedging purposes (e.g., to protect its
    current or intended investments from fluctuations in currency exchange
    rates) as well as for non-hedging purposes.

      A Forward Contract to sell a currency may be entered into where the Fund
    seeks to protect against an anticipated increase in the exchange rate for a
    specific currency which could reduce the dollar value of portfolio
    securities denominated in such currency. Conversely, the Fund may enter into
    a Forward Contract to purchase a given currency to protect against a
    projected increase in the dollar value of securities denominated in such
    currency which the Fund intends to acquire.

      If a hedging transaction in Forward Contracts is successful, the decline
    in the dollar value of portfolio securities or the increase in the dollar
    cost of securities to be acquired may be offset, at least in part, by
    profits on the Forward Contract. Nevertheless, by entering into such Forward
    Contracts, the Fund may be required to forego all or a portion of the
    benefits which otherwise could have been obtained from favorable movements
    in exchange rates. The Fund does not presently intend to hold Forward
    Contracts entered into until the value date, at which time it would be
    required to deliver or accept delivery of the underlying currency, but will
    seek in most instances to close out positions in such Contracts by entering
    into offsetting transactions, which will serve to fix the Fund's profit or
    loss based upon the value of the Contracts at the time the offsetting
    transaction is executed.

      The Fund will also enter into transactions in Forward Contracts for other
    than hedging purposes, which presents greater profit potential but also
    involves increased risk. For example, the Fund may purchase a given foreign
    currency through a Forward Contract if, in the judgment of the Adviser, the
    value of such currency is expected to rise relative to the U.S. dollar.
    Conversely, the Fund may sell the currency through a Forward Contract if the
    Adviser believes that its value will decline relative to the dollar.

      The Fund will profit if the anticipated movements in foreign currency
    exchange rates occur, which will increase its gross income. Where exchange
    rates do not move in the direction or to the extent anticipated, however,
    the Fund may sustain losses which will reduce its gross income. Such
    transactions, therefore, could be considered speculative and could involve
    significant risk of loss.

      The use by the Fund of Forward Contracts also involves the risks described
    under the caption "Special Risk Factors -- Options, Futures, Forwards, Swaps
    and Other Derivative Transactions" in this Appendix.

    FUTURES CONTRACTS
    The Fund may purchase and sell futures contracts ("Futures Contracts") on
    stock indices, foreign currencies, interest rates or interest-rate related
    instruments, indices of foreign currencies or commodities. The Fund may also
    purchase and sell Futures Contracts on foreign or domestic fixed income
    securities or indices of such securities including municipal bond indices
    and any other indices of foreign or domestic fixed income securities that
    may become available for trading. Such investment strategies will be used
    for hedging purposes and for non-hedging purposes, subject to applicable
    law.

      A Futures Contract is a bilateral agreement providing for the purchase and
    sale of a specified type and amount of a financial instrument, foreign
    currency or commodity, or for the making and acceptance of a cash
    settlement, at a stated time in the future for a fixed price. By its terms,
    a Futures Contract provides for a specified settlement month in which, in
    the case of the majority of commodities, interest rate and foreign currency
    futures contracts, the underlying commodities, fixed income securities or
    currency are delivered by the seller and paid for by the purchaser, or on
    which, in the case of index futures contracts and certain interest rate and
    foreign currency futures contracts, the difference between the price at
    which the contract was entered into and the contract's closing value is
    settled between the purchaser and seller in cash. Futures Contracts differ
    from options in that they are bilateral agreements, with both the purchaser
    and the seller equally obligated to complete the transaction. Futures
    Contracts call for settlement only on the expiration date and cannot be
    "exercised" at any other time during their term.

      The purchase or sale of a Futures Contract differs from the purchase or
    sale of a security or the purchase of an option in that no purchase price is
    paid or received. Instead, an amount of cash or cash equivalents, which
    varies but may be as low as 5% or less of the value of the contract, must be
    deposited with the broker as "initial margin." Subsequent payments to and
    from the broker, referred to as "variation margin," are made on a daily
    basis as the value of the index or instrument underlying the Futures
    Contract fluctuates, making positions in the Futures Contract more or less
    valuable -- a process known as "mark-to-market."

      Purchases or sales of stock index futures contracts are used to attempt to
    protect the Fund's current or intended stock investments from broad
    fluctuations in stock prices. For example, the Fund may sell stock index
    futures contracts in anticipation of or during a market decline to attempt
    to offset the decrease in market value of the Fund's securities portfolio
    that might otherwise result. If such decline occurs, the loss in value of
    portfolio securities may be offset, in whole or part, by gains on the
    futures position. When the Fund is not fully invested in the securities
    market and anticipates a significant market advance, it may purchase stock
    index futures contracts in order to gain rapid market exposure that may, in
    part or entirely, offset increases in the cost of securities that the Fund
    intends to purchase. As such purchases are made, the corresponding positions
    in stock index futures contracts will be closed out. In a substantial
    majority of these transactions, the Fund will purchase such securities upon
    termination of the futures position, but under unusual market conditions, a
    long futures position may be terminated without a related purchase of
    securities.

      Interest rate Futures Contracts may be purchased or sold to attempt to
    protect against the effects of interest rate changes on the Fund's current
    or intended investments in fixed income securities. For example, if the Fund
    owned long-term bonds and interest rates were expected to increase, the Fund
    might enter into interest rate futures contracts for the sale of debt
    securities. Such a sale would have much the same effect as selling some of
    the long-term bonds in the Fund's portfolio. If interest rates did increase,
    the value of the debt securities in the portfolio would decline, but the
    value of the Fund's interest rate futures contracts would increase at
    approximately the same rate, subject to the correlation risks described
    below, thereby keeping the net asset value of the Fund from declining as
    much as it otherwise would have.

      Similarly, if interest rates were expected to decline, interest rate
    futures contracts may be purchased to hedge in anticipation of subsequent
    purchases of long-term bonds at higher prices. Since the fluctuations in the
    value of the interest rate futures contracts should be similar to that of
    long-term bonds, the Fund could protect itself against the effects of the
    anticipated rise in the value of long-term bonds without actually buying
    them until the necessary cash became available or the market had stabilized.
    At that time, the interest rate futures contracts could be liquidated and
    the Fund's cash reserves could then be used to buy long-term bonds on the
    cash market. The Fund could accomplish similar results by selling bonds with
    long maturities and investing in bonds with short maturities when interest
    rates are expected to increase. However, since the futures market may be
    more liquid than the cash market in certain cases or at certain times, the
    use of interest rate futures contracts as a hedging technique may allow the
    Fund to hedge its interest rate risk without having to sell its portfolio
    securities.

      The Fund may purchase and sell foreign currency futures contracts for
    hedging purposes, to attempt to protect its current or intended investments
    from fluctuations in currency exchange rates. Such fluctuations could reduce
    the dollar value of portfolio securities denominated in foreign currencies,
    or increase the dollar cost of foreign- denominated securities to be
    acquired, even if the value of such securities in the currencies in which
    they are denominated remains constant. The Fund may sell futures contracts
    on a foreign currency, for example, where it holds securities denominated in
    such currency and it anticipates a decline in the value of such currency
    relative to the dollar. In the event such decline occurs, the resulting
    adverse effect on the value of foreign-denominated securities may be offset,
    in whole or in part, by gains on the futures contracts.

      Conversely, the Fund could protect against a rise in the dollar cost of
    foreign-denominated securities to be acquired by purchasing futures
    contracts on the relevant currency, which could offset, in whole or in part,
    the increased cost of such securities resulting from a rise in the dollar
    value of the underlying currencies. Where the Fund purchases futures
    contracts under such circumstances, however, and the prices of securities to
    be acquired instead decline, the Fund will sustain losses on its futures
    position which could reduce or eliminate the benefits of the reduced cost of
    portfolio securities to be acquired.

      The use by the Fund of Futures Contracts also involves the risks described
    under the caption "Special Risk Factors -- Options, Futures, Forwards, Swaps
    and Other Derivative Transactions" in this Appendix.

    INDEXED SECURITIES
    The Fund may purchase securities with principal and/or interest payments
    whose prices are indexed to the prices of other securities, securities
    indices, currencies, precious metals or other commodities, or other
    financial indicators. Indexed securities typically, but not always, are debt
    securities or deposits whose value at maturity or coupon rate is determined
    by reference to a specific instrument or statistic. The Fund may also
    purchase indexed deposits with similar characteristics. Gold- indexed
    securities, for example, typically provide for a maturity value that depends
    on the price of gold, resulting in a security whose price tends to rise and
    fall together with gold prices. Currency-indexed securities typically are
    short-term to intermediate-term debt securities whose maturity values or
    interest rates are determined by reference to the values of one or more
    specified foreign currencies, and may offer higher yields than U.S. dollar
    denominated securities of equivalent issuers. Currency-indexed securities
    may be positively or negatively indexed; that is, their maturity value may
    increase when the specified currency value increases, resulting in a
    security that performs similarly to a foreign- denominated instrument, or
    their maturity value may decline when foreign currencies increase, resulting
    in a security whose price characteristics are similar to a put on the
    underlying currency. Currency-indexed securities may also have prices that
    depend on the values of a number of different foreign currencies relative to
    each other. Certain indexed securities may expose the Fund to the risk of
    loss of all or a portion of the principal amount of its investment and/or
    the interest that might otherwise have been earned on the amount invested.

      The performance of indexed securities depends to a great extent on the
    performance of the security, currency, or other instrument to which they are
    indexed, and may also be influenced by interest rate changes in the U.S. and
    abroad. At the same time, indexed securities are subject to the credit risks
    associated with the issuer of the security, and their values may decline
    substantially if the issuer's creditworthiness deteriorates. Recent issuers
    of indexed securities have included banks, corporations, and certain U.S.
    Government-sponsored entities.

    INVERSE FLOATING RATE OBLIGATIONS
    The Fund may invest in so-called "inverse floating rate obligations" or
    "residual interest bonds" or other obligations or certificates relating
    thereto structured to have similar features. In creating such an obligation,
    a municipality issues a certain amount of debt and pays a fixed interest
    rate. Half of the debt is issued as variable rate short term obligations,
    the interest rate of which is reset at short intervals, typically 35 days.
    The other half of the debt is issued as inverse floating rate obligations,
    the interest rate of which is calculated based on the difference between a
    multiple of (approximately two times) the interest paid by the issuer and
    the interest paid on the short-term obligation. Under usual circumstances,
    the holder of the inverse floating rate obligation can generally purchase an
    equal principal amount of the short term obligation and link the two
    obligations in order to create long-term fixed rate bonds. Because the
    interest rate on the inverse floating rate obligation is determined by
    subtracting the short-term rate from a fixed amount, the interest rate will
    decrease as the short-term rate increases and will increase as the
    short-term rate decreases. The magnitude of increases and decreases in the
    market value of inverse floating rate obligations may be approximately twice
    as large as the comparable change in the market value of an equal principal
    amount of long-term bonds which bear interest at the rate paid by the issuer
    and have similar credit quality, redemption and maturity provisions.

    INVESTMENT IN OTHER INVESTMENT COMPANIES
    The Fund may invest in other investment companies. The total return on such
    investment will be reduced by the operating expenses and fees of such other
    investment companies, including advisory fees.

      OPEN-END FUNDS. The Fund may invest in open-end investment companies.

      CLOSED-END FUNDS. The Fund may invest in closed-end investment companies.
    Such investment may involve the payment of substantial premiums above the
    value of such investment companies' portfolio securities.

    LENDING OF PORTFOLIO SECURITIES
    The Fund may seek to increase its income by lending portfolio securities.
    Such loans will usually be made only to member firms of the New York Stock
    Exchange (the "Exchange") (and subsidiaries thereof) and member banks of the
    Federal Reserve System, and would be required to be secured continuously by
    collateral in cash, an irrevocable letter of credit or United States
    ("U.S.") Treasury securities maintained on a current basis at an amount at
    least equal to the market value of the securities loaned. The Fund would
    have the right to call a loan and obtain the securities loaned at any time
    on customary industry settlement notice (which will not usually exceed five
    business days). For the duration of a loan, the Fund would continue to
    receive the equivalent of the interest or dividends paid by the issuer on
    the securities loaned. The Fund would also receive a fee from the borrower
    or compensation from the investment of the collateral, less a fee paid to
    the borrower (if the collateral is in the form of cash). The Fund would not,
    however, have the right to vote any securities having voting rights during
    the existence of the loan, but the Fund would call the loan in anticipation
    of an important vote to be taken among holders of the securities or of the
    giving or withholding of their consent on a material matter affecting the
    investment. As with other extensions of credit there are risks of delay in
    recovery or even loss of rights in the collateral should the borrower of the
    securities fail financially. However, the loans would be made only to firms
    deemed by the Adviser to be of good standing, and when, in the judgment of
    the Adviser, the consideration which can be earned currently from securities
    loans of this type justifies the attendant risk.

    LEVERAGING TRANSACTIONS
    The Fund may engage in the types of transactions described below, which
    involve "leverage" because in each case the Fund receives cash which it can
    invest in portfolio securities and has a future obligation to make a
    payment. The use of these transactions by the Fund will generally cause its
    net asset value to increase or decrease at a greater rate than would
    otherwise be the case. Any investment income or gains earned from the
    portfolio securities purchased with the proceeds from these transactions
    which is in excess of the expenses associated from these transactions can be
    expected to cause the value of the Fund's shares and distributions on the
    Fund's shares to rise more quickly than would otherwise be the case.
    Conversely, if the investment income or gains earned from the portfolio
    securities purchased with proceeds from these transactions fail to cover the
    expenses associated with these transactions, the value of the Fund's shares
    is likely to decrease more quickly than otherwise would be the case and
    distributions thereon will be reduced or eliminated. Hence, these
    transactions are speculative, involve leverage and increase the risk of
    owning or investing in the shares of the Fund. These transactions also
    increase the Fund's expenses because of interest and similar payments and
    administrative expenses associated with them. Unless the appreciation and
    income on assets purchased with proceeds from these transactions exceed the
    costs associated with them, the use of these transactions by a Fund would
    diminish the investment performance of the Fund compared with what it would
    have been without using these transactions.

    BANK BORROWINGS: The Fund may borrow money for investment purposes from
    banks and invest the proceeds in accordance with its investment objectives
    and policies.

    MORTGAGE "DOLLAR ROLL" TRANSACTIONS: The Fund may enter into mortgage
    "dollar roll" transactions pursuant to which it sells mortgage-backed
    securities for delivery in the future and simultaneously contracts to
    repurchase substantially similar securities on a specified future date.
    During the roll period, the Fund foregoes principal and interest paid on the
    mortgage-backed securities. The Fund is compensated for the lost interest by
    the difference between the current sales price and the lower price for the
    future purchase (often referred to as the "drop") as well as by the interest
    earned on, and gains from, the investment of the cash proceeds of the
    initial sale. The Fund may also be compensated by receipt of a commitment
    fee.

      If the income and capital gains from the Fund's investment of the cash
    from the initial sale do not exceed the income, capital appreciation and
    gain or loss that would have been realized on the securities sold as part of
    the dollar roll, the use of this technique will diminish the investment
    performance of the Fund compared with what the performance would have been
    without the use of the dollar rolls. Dollar roll transactions involve the
    risk that the market value of the securities the Fund is required to
    purchase may decline below the agreed upon repurchase price of those
    securities. If the broker/dealer to whom the Fund sells securities becomes
    insolvent, the Fund's right to purchase or repurchase securities may be
    restricted. Successful use of mortgage dollar rolls may depend upon the
    Adviser's ability to correctly predict interest rates and prepayments. There
    is no assurance that dollar rolls can be successfully employed.

    REVERSE REPURCHASE AGREEMENTS: The Fund may enter into reverse repurchase
    agreements. In a reverse repurchase agreement, the Fund will sell securities
    and receive cash proceeds, subject to its agreement to repurchase the
    securities at a later date for a fixed price reflecting a market rate of
    interest. There is a risk that the counter party to a reverse repurchase
    agreement will be unable or unwilling to complete the transaction as
    scheduled, which may result in losses to the Fund. The Fund will invest the
    proceeds received under a reverse repurchase agreement in accordance with
    its investment objective and policies.

    OPTIONS
    The Fund may invest in the following types of options, which involve the
    risks described under the caption "Special Risk Factors -- Options, Futures,
    Forwards, Swaps and Other Derivative Transactions" in this Appendix:

    OPTIONS ON FOREIGN CURRENCIES: The Fund may purchase and write options on
    foreign currencies for hedging and non-hedging purposes in a manner similar
    to that in which Futures Contracts on foreign currencies, or Forward
    Contracts, will be utilized. For example, a decline in the dollar value of a
    foreign currency in which portfolio securities are denominated will reduce
    the dollar value of such securities, even if their value in the foreign
    currency remains constant. In order to protect against such diminutions in
    the value of portfolio securities, the Fund may purchase put options on the
    foreign currency. If the value of the currency does decline, the Fund will
    have the right to sell such currency for a fixed amount in dollars and will
    thereby offset, in whole in part, the adverse effect on its portfolio which
    otherwise would have resulted.

      Conversely, where a rise in the dollar value of a currency in which
    securities to be acquired are denominated is projected, thereby increasing
    the cost of such securities, the Fund may purchase call options thereon. The
    purchase of such options could offset, at least partially, the effect of the
    adverse movements in exchange rates. As in the case of other types of
    options, however, the benefit to the Fund deriving from purchases of foreign
    currency options will be reduced by the amount of the premium and related
    transaction costs. In addition, where currency exchange rates do not move in
    the direction or to the extent anticipated, the Fund could sustain losses on
    transactions in foreign currency options which would require it to forego a
    portion or all of the benefits of advantageous changes in such rates. The
    Fund may write options on foreign currencies for the same types of hedging
    purposes. For example, where the Fund anticipates a decline in the dollar
    value of foreign-denominated securities due to adverse fluctuations in
    exchange rates it could, instead of purchasing a put option, write a call
    option on the relevant currency. If the expected decline occurs, the option
    will most likely not be exercised, and the diminution in value of portfolio
    securities will be offset by the amount of the premium received less related
    transaction costs. As in the case of other types of options, therefore, the
    writing of Options on Foreign Currencies will constitute only a partial
    hedge.

      Similarly, instead of purchasing a call option to hedge against an
    anticipated increase in the dollar cost of securities to be acquired, the
    Fund could write a put option on the relevant currency which, if rates move
    in the manner projected, will expire unexercised and allow the Fund to hedge
    such increased cost up to the amount of the premium. Foreign currency
    options written by the Fund will generally be covered in a manner similar to
    the covering of other types of options. As in the case of other types of
    options, however, the writing of a foreign currency option will constitute
    only a partial hedge up to the amount of the premium, and only if rates move
    in the expected direction. If this does not occur, the option may be
    exercised and the Fund would be required to purchase or sell the underlying
    currency at a loss which may not be offset by the amount of the premium.
    Through the writing of options on foreign currencies, the Fund also may be
    required to forego all or a portion of the benefits which might otherwise
    have been obtained from favorable movements in exchange rates. The use of
    foreign currency options for non-hedging purposes, like the use of other
    types of derivatives for such purposes, presents greater profit potential
    but also significant risk of loss and could be considered speculative.

    OPTIONS ON FUTURES CONTRACTS: The Fund also may purchase and write options
    to buy or sell those Futures Contracts in which it may invest ("Options on
    Futures Contracts") as described above under "Futures Contracts." Such
    investment strategies will be used for hedging purposes and for non- hedging
    purposes, subject to applicable law.

      An Option on a Futures Contract provides the holder with the right to
    enter into a "long" position in the underlying Futures Contract, in the case
    of a call option, or a "short" position in the underlying Futures Contract,
    in the case of a put option, at a fixed exercise price up to a stated
    expiration date or, in the case of certain options, on such date. Upon
    exercise of the option by the holder, the contract market clearinghouse
    establishes a corresponding short position for the writer of the option, in
    the case of a call option, or a corresponding long position in the case of a
    put option. In the event that an option is exercised, the parties will be
    subject to all the risks associated with the trading of Futures Contracts,
    such as payment of initial and variation margin deposits. In addition, the
    writer of an Option on a Futures Contract, unlike the holder, is subject to
    initial and variation margin requirements on the option position.

      A position in an Option on a Futures Contract may be terminated by the
    purchaser or seller prior to expiration by effecting a closing purchase or
    sale transaction, subject to the availability of a liquid secondary market,
    which is the purchase or sale of an option of the same type (i.e., the same
    exercise price and expiration date) as the option previously purchased or
    sold. The difference between the premiums paid and received represents the
    Fund's profit or loss on the transaction.

      Options on Futures Contracts that are written or purchased by the Fund on
    U.S. exchanges are traded on the same contract market as the underlying
    Futures Contract, and, like Futures Contracts, are subject to regulation by
    the Commodity Futures Trading Commission (the "CFTC") and the performance
    guarantee of the exchange clearinghouse. In addition, Options on Futures
    Contracts may be traded on foreign exchanges. The Fund may cover the writing
    of call Options on Futures Contracts (a) through purchases of the underlying
    Futures Contract, (b) through ownership of the instrument, or instruments
    included in the index, underlying the Futures Contract, or (c) through the
    holding of a call on the same Futures Contract and in the same principal
    amount as the call written where the exercise price of the call held (i) is
    equal to or less than the exercise price of the call written or (ii) is
    greater than the exercise price of the call written if the Fund owns liquid
    and unencumbered assets equal to the difference. The Fund may cover the
    writing of put Options on Futures Contracts (a) through sales of the
    underlying Futures Contract, (b) through the ownership of liquid and
    unencumbered assets equal to the value of the security or index underlying
    the Futures Contract, or (c) through the holding of a put on the same
    Futures Contract and in the same principal amount as the put written where
    the exercise price of the put held (i) is equal to or greater than the
    exercise price of the put written or where the exercise price of the put
    held (ii) is less than the exercise price of the put written if the Fund
    owns liquid and unencumbered assets equal to the difference. Put and call
    Options on Futures Contracts may also be covered in such other manner as may
    be in accordance with the rules of the exchange on which the option is
    traded and applicable laws and regulations. Upon the exercise of a call
    Option on a Futures Contract written by the Fund, the Fund will be required
    to sell the underlying Futures Contract which, if the Fund has covered its
    obligation through the purchase of such Contract, will serve to liquidate
    its futures position. Similarly, where a put Option on a Futures Contract
    written by the Fund is exercised, the Fund will be required to purchase the
    underlying Futures Contract which, if the Fund has covered its obligation
    through the sale of such Contract, will close out its futures position.

      The writing of a call option on a Futures Contract for hedging purposes
    constitutes a partial hedge against declining prices of the securities or
    other instruments required to be delivered under the terms of the Futures
    Contract. If the futures price at expiration of the option is below the
    exercise price, the Fund will retain the full amount of the option premium,
    less related transaction costs, which provides a partial hedge against any
    decline that may have occurred in the Fund's portfolio holdings. The writing
    of a put option on a Futures Contract constitutes a partial hedge against
    increasing prices of the securities or other instruments required to be
    delivered under the terms of the Futures Contract. If the futures price at
    expiration of the option is higher than the exercise price, the Fund will
    retain the full amount of the option premium which provides a partial hedge
    against any increase in the price of securities which the Fund intends to
    purchase. If a put or call option the Fund has written is exercised, the
    Fund will incur a loss which will be reduced by the amount of the premium it
    receives. Depending on the degree of correlation between changes in the
    value of its portfolio securities and the changes in the value of its
    futures positions, the Fund's losses from existing Options on Futures
    Contracts may to some extent be reduced or increased by changes in the value
    of portfolio securities.

      The Fund may purchase Options on Futures Contracts for hedging purposes
    instead of purchasing or selling the underlying Futures Contracts. For
    example, where a decrease in the value of portfolio securities is
    anticipated as a result of a projected market-wide decline or changes in
    interest or exchange rates, the Fund could, in lieu of selling Futures
    Contracts, purchase put options thereon. In the event that such decrease
    occurs, it may be offset, in whole or in part, by a profit on the option.
    Conversely, where it is projected that the value of securities to be
    acquired by the Fund will increase prior to acquisition, due to a market
    advance or changes in interest or exchange rates, the Fund could purchase
    call Options on Futures Contracts rather than purchasing the underlying
    Futures Contracts.

    OPTIONS ON SECURITIES: The Fund may write (sell) covered put and call
    options, and purchase put and call options, on securities. Call and put
    options written by the Fund may be covered in the manner set forth below.

      A call option written by the Fund 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 for
    additional cash consideration if the Fund owns liquid and unencumbered
    assets equal to the amount of cash consideration) upon conversion or
    exchange of other securities held in its portfolio. A call option is also
    covered if the Fund holds a call on the same security and in the same
    principal amount as the call written where the exercise price of the call
    held (a) is equal to or less than the exercise price of the call written or
    (b) is greater than the exercise price of the call written if the Fund owns
    liquid and unencumbered assets equal to the difference. A put option written
    by the Fund is "covered" if the Fund owns liquid and unencumbered assets
    with a value equal to the exercise price, or else holds a put on the same
    security and in the same principal amount as the put written where the
    exercise price of the put held is equal to or greater than the exercise
    price of the put written or where the exercise price of the put held is less
    than the exercise price of the put written if the Fund owns liquid and
    unencumbered assets equal to the difference. Put and call options written by
    the Fund may also be covered in such other manner as may be in accordance
    with the requirements of the exchange on which, or the counterparty with
    which, the option is traded, and applicable laws and regulations. If the
    writer's obligation is not so covered, it is subject to the risk of the full
    change in value of the underlying security from the time the option is
    written until exercise.

      Effecting a closing transaction in the case of a written call option will
    permit the Fund to write another call option on the underlying security with
    either a different exercise price or expiration date or both, or in the case
    of a written put option will permit the Fund to write another put option to
    the extent that the Fund owns liquid and unencumbered assets. Such
    transactions permit the Fund to generate additional premium income, which
    will partially offset declines in the value of portfolio securities or
    increases in the cost of securities to be acquired. Also, effecting a
    closing transaction will permit the cash or proceeds from the concurrent
    sale of any securities subject to the option to be used for other
    investments of the Fund, provided that another option on such security is
    not written. If the Fund desires to sell a particular security from its
    portfolio on which it has written a call option, it will effect a closing
    transaction in connection with the option prior to or concurrent with the
    sale of the security.

      The Fund will realize a profit from a closing transaction if the premium
    paid in connection with the closing of an option written by the Fund is less
    than the premium received from writing the option, or if the premium
    received in connection with the closing of an option purchased by the Fund
    is more than the premium paid for the original purchase. Conversely, the
    Fund will suffer a loss if the premium paid or received in connection with a
    closing transaction is more or less, respectively, than the premium received
    or paid in establishing the option position. Because increases in the market
    price of a call option will generally reflect increases in the market price
    of the underlying security, any loss resulting from the repurchase of a call
    option previously written by the Fund is likely to be offset in whole or in
    part by appreciation of the underlying security owned by the Fund.

      The Fund may write options in connection with buy-and-write transactions;
    that is, the Fund may purchase a security and then write a call option
    against that security. The exercise price of the call option the Fund
    determines to write will depend upon the expected price movement of the
    underlying security. The exercise price of a call option may be below
    ("in-the-money"), equal to ("at-the-money") or above ("out-of-the- money")
    the current value of the underlying security at the time the option is
    written. Buy-and-write transactions using in-the-money call options may be
    used when it is expected that the price of the underlying security will
    decline moderately during the option period. Buy-and-write transactions
    using out-of-the-money call options may be used when it is expected that the
    premiums received from writing the call option plus the appreciation in the
    market price of the underlying security up to the exercise price will be
    greater than the appreciation in the price of the underlying security alone.
    If the call options are exercised in such transactions, the Fund's maximum
    gain will be the premium received by it for writing the option, adjusted
    upwards or downwards by the difference between the Fund's purchase price of
    the security and the exercise price, less related transaction costs. If the
    options are not exercised and the price of the underlying security declines,
    the amount of such decline will be offset in part, or entirely, by the
    premium received.

      The writing of covered put options is similar in terms of risk/return
    characteristics to buy-and-write transactions. If the market price of the
    underlying security rises or otherwise is above the exercise price, the put
    option will expire worthless and the Fund's gain will be limited to the
    premium received, less related transaction costs. If the market price of the
    underlying security declines or otherwise is below the exercise price, the
    Fund may elect to close the position or retain the option until it is
    exercised, at which time the Fund will be required to take delivery of the
    security at the exercise price; the Fund's return will be the premium
    received from the put option minus the amount by which the market price of
    the security is below the exercise price, which could result in a loss.
    Out-of-the-money, at-the-money and in-the-money put options may be used by
    the Fund in the same market environments that call options are used in
    equivalent buy-and-write transactions.

      The Fund may also write combinations of put and call options on the same
    security, known as "straddles" with the same exercise price and expiration
    date. By writing a straddle, the Fund undertakes a simultaneous obligation
    to sell and purchase the same security in the event that one of the options
    is exercised. If the price of the security subsequently rises sufficiently
    above the exercise price to cover the amount of the premium and transaction
    costs, the call will likely be exercised and the Fund will be required to
    sell the underlying security at a below market price. This loss may be
    offset, however, in whole or part, by the premiums received on the writing
    of the two options. Conversely, if the price of the security declines by a
    sufficient amount, the put will likely be exercised. The writing of
    straddles will likely be effective, therefore, only where the price of the
    security remains stable and neither the call nor the put is exercised. In
    those instances where one of the options is exercised, the loss on the
    purchase or sale of the underlying security may exceed the amount of the
    premiums received.

      By writing a call option, the Fund limits its opportunity to profit from
    any increase in the market value of the underlying security above the
    exercise price of the option. By writing a put option, the Fund assumes the
    risk that it may be required to purchase the underlying security for an
    exercise price above its then-current market value, resulting in a capital
    loss unless the security subsequently appreciates in value. The writing of
    options on securities will not be undertaken by the Fund solely for hedging
    purposes, and could involve certain risks which are not present in the case
    of hedging transactions. Moreover, even where options are written for
    hedging purposes, such transactions constitute only a partial hedge against
    declines in the value of portfolio securities or against increases in the
    value of securities to be acquired, up to the amount of the premium.

      The Fund may also purchase options for hedging purposes or to increase its
    return. Put options may be purchased to hedge against a decline in the value
    of portfolio securities. If such decline occurs, the put options will permit
    the Fund to sell the securities at the exercise price, or to close out the
    options at a profit. By using put options in this way, the Fund will reduce
    any profit it might otherwise have realized in the underlying security by
    the amount of the premium paid for the put option and by transaction costs.

      The Fund may also purchase call options to hedge against an increase in
    the price of securities that the Fund anticipates purchasing in the future.
    If such increase occurs, the call option will permit the Fund to purchase
    the securities at the exercise price, or to close out the options at a
    profit. The premium paid for the call option plus any transaction costs will
    reduce the benefit, if any, realized by the Fund upon exercise of the
    option, and, unless the price of the underlying security rises sufficiently,
    the option may expire worthless to the Fund.

    OPTIONS ON STOCK INDICES: The Fund may write (sell) covered call and put
    options and purchase call and put options on stock indices. In contrast to
    an option on a security, an option on a stock index provides the holder with
    the right but not the obligation to make or receive a cash settlement upon
    exercise of the option, rather than the right to purchase or sell a
    security. The amount of this settlement is generally equal to (i) the
    amount, if any, by which the fixed exercise price of the option exceeds (in
    the case of a call) or is below (in the case of a put) the closing value of
    the underlying index on the date of exercise, multiplied by (ii) a fixed
    "index multiplier." The Fund may cover written call options on stock indices
    by owning securities whose price changes, in the opinion of the Adviser, are
    expected to be similar to those of the underlying index, or by having an
    absolute and immediate right to acquire such securities without additional
    cash consideration (or for additional cash consideration if the Fund owns
    liquid and unencumbered assets equal to the amount of cash consideration)
    upon conversion or exchange of other securities in its portfolio. Where the
    Fund covers a call option on a stock index through ownership of securities,
    such securities may not match the composition of the index and, in that
    event, the Fund will not be fully covered and could be subject to risk of
    loss in the event of adverse changes in the value of the index. The Fund may
    also cover call options on stock indices by holding a call on the same index
    and in the same principal amount as the call written where the exercise
    price of the call held (a) is equal to or less than the exercise price of
    the call written or (b) is greater than the exercise price of the call
    written if the Fund owns liquid and unencumbered assets equal to the
    difference. The Fund may cover put options on stock indices by owning liquid
    and unencumbered assets with a value equal to the exercise price, or by
    holding a put on the same stock index and in the same principal amount as
    the put written where the exercise price of the put held (a) is equal to or
    greater than the exercise price of the put written or (b) is less than the
    exercise price of the put written if the Fund owns liquid and unencumbered
    assets equal to the difference. Put and call options on stock indices may
    also be covered in such other manner as may be in accordance with the rules
    of the exchange on which, or the counterparty with which, the option is
    traded and applicable laws and regulations.

      The Fund will receive a premium from writing a put or call option, which
    increases the Fund's gross income in the event the option expires
    unexercised or is closed out at a profit. If the value of an index on which
    the Fund has written a call option falls or remains the same, the Fund will
    realize a profit in the form of the premium received (less transaction
    costs) that could offset all or a portion of any decline in the value of the
    securities it owns. If the value of the index rises, however, the Fund will
    realize a loss in its call option position, which will reduce the benefit of
    any unrealized appreciation in the Fund's stock investments. By writing a
    put option, the Fund assumes the risk of a decline in the index. To the
    extent that the price changes of securities owned by the Fund correlate with
    changes in the value of the index, writing covered put options on indices
    will increase the Fund's losses in the event of a market decline, although
    such losses will be offset in part by the premium received for writing the
    option.

      The Fund may also purchase put options on stock indices to hedge its
    investments against a decline in value. By purchasing a put option on a
    stock index, the Fund will seek to offset a decline in the value of
    securities it owns through appreciation of the put option. If the value of
    the Fund's investments does not decline as anticipated, or if the value of
    the option does not increase, the Fund's loss will be limited to the premium
    paid for the option plus related transaction costs. The success of this
    strategy will largely depend on the accuracy of the correlation between the
    changes in value of the index and the changes in value of the Fund's
    security holdings.

      The purchase of call options on stock indices may be used by the Fund to
    attempt to reduce the risk of missing a broad market advance, or an advance
    in an industry or market segment, at a time when the Fund holds uninvested
    cash or short-term debt securities awaiting investment. When purchasing call
    options for this purpose, the Fund will also bear the risk of losing all or
    a portion of the premium paid if the value of the index does not rise. The
    purchase of call options on stock indices when the Fund is substantially
    fully invested is a form of leverage, up to the amount of the premium and
    related transaction costs, and involves risks of loss and of increased
    volatility similar to those involved in purchasing calls on securities the
    Fund owns.

      The index underlying a stock index option may be a "broad-based" index,
    such as the Standard & Poor's 500 Index or the New York Stock Exchange
    Composite Index, the changes in value of which ordinarily will reflect
    movements in the stock market in general. In contrast, certain options may
    be based on narrower market indices, such as the Standard & Poor's 100
    Index, or on indices of securities of particular industry groups, such as
    those of oil and gas or technology companies. A stock index assigns relative
    values to the stocks included in the index and the index fluctuates with
    changes in the market values of the stocks so included. The composition of
    the index is changed periodically.

    RESET OPTIONS:
    In certain instances, the Fund may purchase or write options on U.S.
    Treasury securities which provide for periodic adjustment of the strike
    price and may also provide for the periodic adjustment of the premium during
    the term of each such option. Like other types of options, these
    transactions, which may be referred to as "reset" options or "adjustable
    strike" options grant the purchaser the right to purchase (in the case of a
    call) or sell (in the case of a put), a specified type of U.S. Treasury
    security at any time up to a stated expiration date (or, in certain
    instances, on such date). In contrast to other types of options, however,
    the price at which the underlying security may be purchased or sold under a
    "reset" option is determined at various intervals during the term of the
    option, and such price fluctuates from interval to interval based on changes
    in the market value of the underlying security. As a result, the strike
    price of a "reset" option, at the time of exercise, may be less advantageous
    than if the strike price had been fixed at the initiation of the option. In
    addition, the premium paid for the purchase of the option may be determined
    at the termination, rather than the initiation, of the option. If the
    premium for a reset option written by the Fund is paid at termination, the
    Fund assumes the risk that (i) the premium may be less than the premium
    which would otherwise have been received at the initiation of the option
    because of such factors as the volatility in yield of the underlying
    Treasury security over the term of the option and adjustments made to the
    strike price of the option, and (ii) the option purchaser may default on its
    obligation to pay the premium at the termination of the option. Conversely,
    where the Fund purchases a reset option, it could be required to pay a
    higher premium than would have been the case at the initiation of the
    option.

    "YIELD CURVE" OPTIONS: The Fund may also enter into options on the "spread,"
    or yield differential, between two fixed income securities, in transactions
    referred to as "yield curve" options. In contrast to other types of options,
    a yield curve option is based on the difference between the yields of
    designated securities, rather than the prices of the individual securities,
    and is settled through cash payments. Accordingly, a yield curve option is
    profitable to the holder if this differential widens (in the case of a call)
    or narrows (in the case of a put), regardless of whether the yields of the
    underlying securities increase or decrease.

      Yield curve options may be used for the same purposes as other options on
    securities. Specifically, the Fund may purchase or write such options for
    hedging purposes. For example, the Fund may purchase a call option on the
    yield spread between two securities, if it owns one of the securities and
    anticipates purchasing the other security and wants to hedge against an
    adverse change in the yield spread between the two securities. The Fund may
    also purchase or write yield curve options for other than hedging purposes
    (i.e., in an effort to increase its current income) if, in the judgment of
    the Adviser, the Fund will be able to profit from movements in the spread
    between the yields of the underlying securities. The trading of yield curve
    options is subject to all of the risks associated with the trading of other
    types of options. In addition, however, such options present risk of loss
    even if the yield of one of the underlying securities remains constant, if
    the spread moves in a direction or to an extent which was not anticipated.
    Yield curve options written by the Fund will be "covered". A call (or put)
    option is covered if the Fund holds another call (or put) option on the
    spread between the same two securities and owns liquid and unencumbered
    assets sufficient to cover the Fund's net liability under the two options.
    Therefore, the Fund's liability for such a covered option is generally
    limited to the difference between the amount of the Fund's liability under
    the option written by the Fund less the value of the option held by the
    Fund. Yield curve options may also be covered in such other manner as may be
    in accordance with the requirements of the counterparty with which the
    option is traded and applicable laws and regulations. Yield curve options
    are traded over-the-counter and because they have been only recently
    introduced, established trading markets for these securities have not yet
    developed.

    REPURCHASE AGREEMENTS
    The Fund may enter into repurchase agreements with sellers who are member
    firms (or a subsidiary thereof) of the New York Stock Exchange or members of
    the Federal Reserve System, recognized primary U.S. Government securities
    dealers or institutions which the Adviser has determined to be of comparable
    creditworthiness. The securities that the Fund purchases and holds through
    its agent are U.S. Government securities, the values of which are equal to
    or greater than the repurchase price agreed to be paid by the seller. The
    repurchase price may be higher than the purchase price, the difference being
    income to the Fund, or the purchase and repurchase prices may be the same,
    with interest at a standard rate due to the Fund together with the
    repurchase price on repurchase. In either case, the income to the Fund is
    unrelated to the interest rate on the Government securities.

      The repurchase agreement provides that in the event the seller fails to
    pay the amount agreed upon on the agreed upon delivery date or upon demand,
    as the case may be, the Fund will have the right to liquidate the
    securities. If at the time the Fund is contractually entitled to exercise
    its right to liquidate the securities, the seller is subject to a proceeding
    under the bankruptcy laws or its assets are otherwise subject to a stay
    order, the Fund's exercise of its right to liquidate the securities may be
    delayed and result in certain losses and costs to the Fund. The Fund has
    adopted and follows procedures which are intended to minimize the risks of
    repurchase agreements. For example, the Fund only enters into repurchase
    agreements after the Adviser has determined that the seller is creditworthy,
    and the Adviser monitors that seller's creditworthiness on an ongoing basis.
    Moreover, under such agreements, the value of the securities (which are
    marked to market every business day) is required to be greater than the
    repurchase price, and the Fund has the right to make margin calls at any
    time if the value of the securities falls below the agreed upon collateral.

    RESTRICTED SECURITIES
    The Fund may purchase securities that are not registered under the
    Securities Act of 1933, as amended ("1933 Act") ("restricted securities"),
    including those that can be offered and sold to "qualified institutional
    buyers" under Rule 144A under the 1933 Act ("Rule 144A securities") and
    commercial paper issued under Section 4(2) of the 1933 Act ("4(2) Paper"). A
    determination is made, based upon a continuing review of the trading markets
    for the Rule 144A security or 4(2) Paper, whether such security is liquid
    and thus not subject to the Fund's limitation on investing in illiquid
    investments. The Board of Trustees has adopted guidelines and delegated to
    MFS the daily function of determining and monitoring the liquidity of Rule
    144A securities and 4(2) Paper. The Board, however, retains oversight of the
    liquidity determinations focusing on factors such as valuation, liquidity
    and availability of information. Investing in Rule 144A securities could
    have the effect of decreasing the level of liquidity in the Fund to the
    extent that qualified institutional buyers become for a time uninterested in
    purchasing these Rule 144A securities held in the Fund's portfolio. Subject
    to the Fund's limitation on investments in illiquid investments, the Fund
    may also invest in restricted securities that may not be sold under Rule
    144A, which presents certain risks. As a result, the Fund might not be able
    to sell these securities when the Adviser wishes to do so, or might have to
    sell them at less than fair value. In addition, market quotations are less
    readily available. Therefore, judgment may at times play a greater role in
    valuing these securities than in the case of unrestricted securities.

    SHORT SALES
    The Fund may seek to hedge investments or realize additional gains through
    short sales. The Fund may make short sales, which are transactions in which
    the Fund sells a security it does not own, in anticipation of a decline in
    the market value of that security. To complete such a transaction, the Fund
    must borrow the security to make delivery to the buyer. The Fund then is
    obligated to replace the security borrowed by purchasing it at the market
    price at the time of replacement. The price at such time may be more or less
    than the price at which the security was sold by the Fund. Until the
    security is replaced, the Fund is required to repay the lender any dividends
    or interest which accrue during the period of the loan. To borrow the
    security, the Fund also may be required to pay a premium, which would
    increase the cost of the security sold. The net proceeds of the short sale
    will be retained by the broker, to the extent necessary to meet margin
    requirements, until the short position is closed out. The Fund also will
    incur transaction costs in effecting short sales.

      The Fund will incur a loss as a result of the short sale if the price of
    the security increases between the date of the short sale and the date on
    which the Fund replaces the borrowed security. The Fund will realize a gain
    if the price of the security declines between those dates. The amount of any
    gain will be decreased, and the amount of any loss increased, by the amount
    of the premium, dividends or interest the Fund may be required to pay in
    connection with a short sale.

      Whenever the Fund engages in short sales, it identifies liquid and
    unencumbered assets in an amount that, when combined with the amount of
    collateral deposited with the broker connection with the short sale, equals
    the current market value of the security sold short.

    SHORT SALES AGAINST THE BOX
    The Fund may make short sales "against the box," i.e., when a security
    identical to one owned by the Fund is borrowed and sold short. If the Fund
    enters into a short sale against the box, it is required to segregate
    securities equivalent in kind and amount to the securities sold short (or
    securities convertible or exchangeable into such securities) and is required
    to hold such securities while the short sale is outstanding. The Fund will
    incur transaction costs, including interest, in connection with opening,
    maintaining, and closing short sales against the box.


    SHORT TERM INSTRUMENTS

    The Fund may hold cash and invest in cash equivalents, such as short-term
    U.S. Government Securities, commercial paper and bank instruments.

    SWAPS AND RELATED DERIVATIVE INSTRUMENTS
    The Fund may enter into interest rate swaps, currency swaps and other types
    of available swap agreements, including swaps on securities, commodities and
    indices, and related types of derivatives, such as caps, collars and floors.
    A swap is an agreement between two parties pursuant to which each party
    agrees to make one or more payments to the other on regularly scheduled
    dates over a stated term, based on different interest rates, currency
    exchange rates, security or commodity prices, the prices or rates of other
    types of financial instruments or assets or the levels of specified indices.
    Under a typical swap, one party may agree to pay a fixed rate or a floating
    rate determined by reference to a specified instrument, rate or index,
    multiplied in each case by a specified amount (the "notional amount"), while
    the other party agrees to pay an amount equal to a different floating rate
    multiplied by the same notional amount. On each payment date, the
    obligations of parties are netted, with only the net amount paid by one
    party to the other. All swap agreements entered into by the Fund with the
    same counterparty are generally governed by a single master agreement, which
    provides for the netting of all amounts owed by the parties under the
    agreement upon the occurrence of an event of default, thereby reducing the
    credit risk to which such party is exposed.

      Swap agreements are typically individually negotiated and structured to
    provide exposure to a variety of different types of investments or market
    factors. Swap agreements may be entered into for hedging or non-hedging
    purposes and therefore may increase or decrease the Fund's exposure to the
    underlying instrument, rate, asset or index. Swap agreements can take many
    different forms and are known by a variety of names. The Fund is not limited
    to any particular form or variety of swap agreement if the Adviser
    determines it is consistent with the Fund's investment objective and
    policies.

      For example, the Fund may enter into an interest rate swap in order to
    protect against declines in the value of fixed income securities held by the
    Fund. In such an instance, the Fund would agree with a counterparty to pay a
    fixed rate (multiplied by a notional amount) and the counterparty would
    agree to pay a floating rate multiplied by the same notional amount. If
    interest rates rise, resulting in a diminution in the value of the Fund's
    portfolio, the Fund would receive payments under the swap that would offset,
    in whole or part, such diminution in value. The Fund may also enter into
    swaps to modify its exposure to particular markets or instruments, such as a
    currency swap between the U.S. dollar and another currency which would have
    the effect of increasing or decreasing the Fund's exposure to each such
    currency. The Fund might also enter into a swap on a particular security, or
    a basket or index of securities, in order to gain exposure to the underlying
    security or securities, as an alternative to purchasing such securities.
    Such transactions could be more efficient or less costly in certain
    instances than an actual purchase or sale of the securities.

      The Fund may enter into other related types of over-the-counter
    derivatives, such as "caps", "floors", "collars" and options on swaps, or
    "swaptions", for the same types of hedging or non-hedging purposes. Caps and
    floors are similar to swaps, except that one party pays a fee at the time
    the transaction is entered into and has no further payment obligations,
    while the other party is obligated to pay an amount equal to the amount by
    which a specified fixed or floating rate exceeds or is below another rate
    (multiplied by a notional amount). Caps and floors, therefore, are also
    similar to options. A collar is in effect a combination of a cap and a
    floor, with payments made only within or outside a specified range of prices
    or rates. A swaption is an option to enter into a swap agreement. Like other
    types of options, the buyer of a swaption pays a non-refundable premium for
    the option and obtains the right, but not the obligation, to enter into the
    underlying swap on the agreed-upon terms.

      The Fund will maintain liquid and unencumbered assets to cover its current
    obligations under swap and other over-the-counter derivative transactions.
    If the Fund enters into a swap agreement on a net basis (i.e., the two
    payment streams are netted out, with the Fund receiving or paying, as the
    case may be, only the net amount of the two payments), the Fund will
    maintain liquid and unencumbered assets with a daily value at least equal to
    the excess, if any, of the Fund's accrued obligations under the swap
    agreement over the accrued amount the Fund is entitled to receive under the
    agreement. If the Fund enters into a swap agreement on other than a net
    basis, it will maintain liquid and unencumbered assets with a value equal to
    the full amount of the Fund's accrued obligations under the agreement.

      The most significant factor in the performance of swaps, caps, floors and
    collars is the change in the underlying price, rate or index level that
    determines the amount of payments to be made under the arrangement. If the
    Adviser is incorrect in its forecasts of such factors, the investment
    performance of the Fund would be less than what it would have been if these
    investment techniques had not been used. If a swap agreement calls for
    payments by the Fund, the Fund must be prepared to make such payments when
    due. In addition, if the counterparty's creditworthiness would decline, the
    value of the swap agreement would be likely to decline, potentially
    resulting in losses.

      If the counterparty defaults, the Fund's risk of loss consists of the net
    amount of payments that the Fund is contractually entitled to receive. The
    Fund anticipates that it will be able to eliminate or reduce its exposure
    under these arrangements by assignment or other disposition or by entering
    into an offsetting agreement with the same or another counterparty, but
    there can be no assurance that it will be able to do so.

      The uses by the Fund of swaps and related derivative instruments also
    involves the risks described under the caption "Special Risk Factors --
    Options, Futures, Forwards, Swaps and Other Derivative Transactions" in
    this Appendix.

    TEMPORARY BORROWINGS
    The Fund may borrow money for temporary purposes (e.g., to meet redemption
    requests or settle outstanding purchases of portfolio securities).

    TEMPORARY DEFENSIVE POSITIONS
    During periods of unusual market conditions when the Adviser believes that
    investing for temporary defensive purposes is appropriate, or in order to
    meet anticipated redemption requests, a large portion or all of the assets
    of the Fund may be invested in cash (including foreign currency) or cash
    equivalents, including, but not limited to, obligations of banks (including
    certificates of deposit, bankers' acceptances, time deposits and repurchase
    agreements), commercial paper, short-term notes, U.S. Government Securities
    and related repurchase agreements.

    WARRANTS
    The Fund may invest in warrants. Warrants are securities that give the Fund
    the right to purchase equity securities from the issuer at a specific price
    (the "strike price") for a limited period of time. The strike price of
    warrants typically is much lower than the current market price of the
    underlying securities, yet they are subject to similar price fluctuations.
    As a result, warrants may be more volatile investments than the underlying
    securities and may offer greater potential for capital appreciation as well
    as capital loss. Warrants do not entitle a holder to dividends or voting
    rights with respect to the underlying securities and do not represent any
    rights in the assets of the issuing company. Also, the value of the warrant
    does not necessarily change with the value of the underlying securities and
    a warrant ceases to have value if it is not exercised prior to the
    expiration date. These factors can make warrants more speculative than other
    types of investments.

    "WHEN-ISSUED" SECURITIES
    The Fund may purchase securities on a "when-issued" or on a "forward
    delivery" basis which means that the securities will be delivered to the
    Fund at a future date usually beyond customary settlement time. The
    commitment to purchase a security for which payment will be made on a future
    date may be deemed a separate security. In general, the Fund does not pay
    for such securities until received, and does not start earning interest on
    the securities until the contractual settlement date. While awaiting
    delivery of securities purchased on such bases, a Fund will identify liquid
    and unencumbered assets equal to its forward delivery commitment.

    SPECIAL RISK FACTORS -- OPTIONS, FUTURES, FORWARDS, SWAPS AND OTHER
    DERIVATIVE TRANSACTIONS

    RISK OF IMPERFECT CORRELATION OF HEDGING INSTRUMENTS WITH THE FUND'S
    PORTFOLIO: The Fund's ability effectively to hedge all or a portion of its
    portfolio through transactions in derivatives, including options, Futures
    Contracts, Options on Futures Contracts, Forward Contracts, swaps and other
    types of derivatives depends on the degree to which price movements in the
    underlying index or instrument correlate with price movements in the
    relevant portion of the Fund's portfolio. In the case of derivative
    instruments based on an index, the portfolio will not duplicate the
    components of the index, and in the case of derivative instruments on fixed
    income securities, the portfolio securities which are being hedged may not
    be the same type of obligation underlying such derivatives. The use of
    derivatives for "cross hedging" purposes (such as a transaction in a Forward
    Contract on one currency to hedge exposure to a different currency) may
    involve greater correlation risks. Consequently, the Fund bears the risk
    that the price of the portfolio securities being hedged will not move in the
    same amount or direction as the underlying index or obligation.

      If the Fund purchases a put option on an index and the index decreases
    less than the value of the hedged securities, the Fund would experience a
    loss which is not completely offset by the put option. It is also possible
    that there may be a negative correlation between the index or obligation
    underlying an option or Futures Contract in which the Fund has a position
    and the portfolio securities the Fund is attempting to hedge, which could
    result in a loss on both the portfolio and the hedging instrument. It should
    be noted that stock index futures contracts or options based upon a narrower
    index of securities, such as those of a particular industry group, may
    present greater risk than options or futures based on a broad market index.
    This is due to the fact that a narrower index is more susceptible to rapid
    and extreme fluctuations as a result of changes in the value of a small
    number of securities. Nevertheless, where the Fund enters into transactions
    in options or futures on narrowly-based indices for hedging purposes,
    movements in the value of the index should, if the hedge is successful,
    correlate closely with the portion of the Fund's portfolio or the intended
    acquisitions being hedged.

      The trading of derivatives for hedging purposes entails the additional
    risk of imperfect correlation between movements in the price of the
    derivative and the price of the underlying index or obligation. The
    anticipated spread between the prices may be distorted due to the
    differences in the nature of the markets such as differences in margin
    requirements, the liquidity of such markets and the participation of
    speculators in the derivatives markets. In this regard, trading by
    speculators in derivatives has in the past occasionally resulted in market
    distortions, which may be difficult or impossible to predict, particularly
    near the expiration of such instruments.

      The trading of Options on Futures Contracts also entails the risk that
    changes in the value of the underlying Futures Contracts will not be fully
    reflected in the value of the option. The risk of imperfect correlation,
    however, generally tends to diminish as the maturity date of the Futures
    Contract or expiration date of the option approaches.

      Further, with respect to options on securities, options on stock indices,
    options on currencies and Options on Futures Contracts, the Fund is subject
    to the risk of market movements between the time that the option is
    exercised and the time of performance thereunder. This could increase the
    extent of any loss suffered by the Fund in connection with such
    transactions.

      In writing a covered call option on a security, index or futures contract,
    the Fund also incurs the risk that changes in the value of the instruments
    used to cover the position will not correlate closely with changes in the
    value of the option or underlying index or instrument. For example, where
    the Fund covers a call option written on a stock index through segregation
    of securities, such securities may not match the composition of the index,
    and the Fund may not be fully covered. As a result, the Fund could be
    subject to risk of loss in the event of adverse market movements.

      The writing of options on securities, options on stock indices or Options
    on Futures Contracts constitutes only a partial hedge against fluctuations
    in the value of the Fund's portfolio. When the Fund writes an option, it
    will receive premium income in return for the holder's purchase of the right
    to acquire or dispose of the underlying obligation. In the event that the
    price of such obligation does not rise sufficiently above the exercise price
    of the option, in the case of a call, or fall below the exercise price, in
    the case of a put, the option will not be exercised and the Fund will retain
    the amount of the premium, less related transaction costs, which will
    constitute a partial hedge against any decline that may have occurred in the
    Fund's portfolio holdings or any increase in the cost of the instruments to
    be acquired.

      Where the price of the underlying obligation moves sufficiently in favor
    of the holder to warrant exercise of the option, however, and the option is
    exercised, the Fund will incur a loss which may only be partially offset by
    the amount of the premium it received. Moreover, by writing an option, the
    Fund may be required to forego the benefits which might otherwise have been
    obtained from an increase in the value of portfolio securities or other
    assets or a decline in the value of securities or assets to be acquired. In
    the event of the occurrence of any of the foregoing adverse market events,
    the Fund's overall return may be lower than if it had not engaged in the
    hedging transactions. Furthermore, the cost of using these techniques may
    make it economically infeasible for the Fund to engage in such transactions.

    RISKS OF NON-HEDGING TRANSACTIONS: The Fund may enter transactions in
    derivatives for non-hedging purposes as well as hedging purposes. Non-
    hedging transactions in such instruments involve greater risks and may
    result in losses which may not be offset by increases in the value of
    portfolio securities or declines in the cost of securities to be acquired.
    The Fund will only write covered options, such that liquid and unencumbered
    assets necessary to satisfy an option exercise will be identified, unless
    the option is covered in such other manner as may be in accordance with the
    rules of the exchange on which, or the counterparty with which, the option
    is traded and applicable laws and regulations. Nevertheless, the method of
    covering an option employed by the Fund may not fully protect it against
    risk of loss and, in any event, the Fund could suffer losses on the option
    position which might not be offset by corresponding portfolio gains. The
    Fund may also enter into futures, Forward Contracts or swaps for non-hedging
    purposes. For example, the Fund may enter into such a transaction as an
    alternative to purchasing or selling the underlying instrument or to obtain
    desired exposure to an index or market. In such instances, the Fund will be
    exposed to the same economic risks incurred in purchasing or selling the
    underlying instrument or instruments. However, transactions in futures,
    Forward Contracts or swaps may be leveraged, which could expose the Fund to
    greater risk of loss than such purchases or sales. Entering into
    transactions in derivatives for other than hedging purposes, therefore,
    could expose the Fund to significant risk of loss if the prices, rates or
    values of the underlying instruments or indices do not move in the direction
    or to the extent anticipated.

      With respect to the writing of straddles on securities, the Fund incurs
    the risk that the price of the underlying security will not remain stable,
    that one of the options written will be exercised and that the resulting
    loss will not be offset by the amount of the premiums received. Such
    transactions, therefore, create an opportunity for increased return by
    providing the Fund with two simultaneous premiums on the same security, but
    involve additional risk, since the Fund may have an option exercised against
    it regardless of whether the price of the security increases or decreases.

    RISK OF A POTENTIAL LACK OF A LIQUID SECONDARY MARKET: Prior to exercise or
    expiration, a futures or option position can only be terminated by entering
    into a closing purchase or sale transaction. This requires a secondary
    market for such instruments on the exchange on which the initial transaction
    was entered into. While the Fund will enter into options or futures
    positions only if there appears to be a liquid secondary market therefor,
    there can be no assurance that such a market will exist for any particular
    contract at any specific time. In that event, it may not be possible to
    close out a position held by the Fund, and the Fund could be required to
    purchase or sell the instrument underlying an option, make or receive a cash
    settlement or meet ongoing variation margin requirements. Under such
    circumstances, if the Fund has insufficient cash available to meet margin
    requirements, it will be necessary to liquidate portfolio securities or
    other assets at a time when it is disadvantageous to do so. The inability to
    close out options and futures positions, therefore, could have an adverse
    impact on the Fund's ability effectively to hedge its portfolio, and could
    result in trading losses.

      The liquidity of a secondary market in a Futures Contract or option
    thereon may be adversely affected by "daily price fluctuation limits,"
    established by exchanges, which limit the amount of fluctuation in the price
    of a contract during a single trading day. Once the daily limit has been
    reached in the contract, no trades may be entered into at a price beyond the
    limit, thus preventing the liquidation of open futures or option positions
    and requiring traders to make additional margin deposits. Prices have in the
    past moved to the daily limit on a number of consecutive trading days.

      The trading of Futures Contracts and options is also subject to the risk
    of trading halts, suspensions, exchange or clearinghouse equipment failures,
    government intervention, insolvency of a brokerage firm or clearinghouse or
    other disruptions of normal trading activity, which could at times make it
    difficult or impossible to liquidate existing positions or to recover excess
    variation margin payments.

    MARGIN: Because of low initial margin deposits made upon the establishment
    of a futures, forward or swap position (certain of which may require no
    initial margin deposits) and the writing of an option, such transactions
    involve substantial leverage. As a result, relatively small movements in the
    price of the contract can result in substantial unrealized gains or losses.
    Where the Fund enters into such transactions for hedging purposes, any
    losses incurred in connection therewith should, if the hedging strategy is
    successful, be offset, in whole or in part, by increases in the value of
    securities or other assets held by the Fund or decreases in the prices of
    securities or other assets the Fund intends to acquire. Where the Fund
    enters into such transactions for other than hedging purposes, the margin
    requirements associated with such transactions could expose the Fund to
    greater risk.

    POTENTIAL BANKRUPTCY OF A CLEARINGHOUSE OR BROKER: When the Fund enters into
    transactions in exchange-traded futures or options, it is exposed to the
    risk of the potential bankruptcy of the relevant exchange clearinghouse or
    the broker through which the Fund has effected the transaction. In that
    event, the Fund might not be able to recover amounts deposited as margin, or
    amounts owed to the Fund in connection with its transactions, for an
    indefinite period of time, and could sustain losses of a portion or all of
    such amounts. Moreover, the performance guarantee of an exchange
    clearinghouse generally extends only to its members and the Fund could
    sustain losses, notwithstanding such guarantee, in the event of the
    bankruptcy of its broker.

    TRADING AND POSITION LIMITS: The exchanges on which futures and options are
    traded may impose limitations governing the maximum number of positions on
    the same side of the market and involving the same underlying instrument
    which may be held by a single investor, whether acting alone or in concert
    with others (regardless of whether such contracts are held on the same or
    different exchanges or held or written in one or more accounts or through
    one or more brokers). Further, the CFTC and the various contract markets
    have established limits referred to as "speculative position limits" on the
    maximum net long or net short position which any person may hold or control
    in a particular futures or option contract. An exchange may order the
    liquidation of positions found to be in violation of these limits and it may
    impose other sanctions or restrictions. The Adviser does not believe that
    these trading and position limits will have any adverse impact on the
    strategies for hedging the portfolios of the Fund.

    RISKS OF OPTIONS ON FUTURES CONTRACTS: The amount of risk the Fund assumes
    when it purchases an Option on a Futures Contract is the premium paid for
    the option, plus related transaction costs. In order to profit from an
    option purchased, however, it may be necessary to exercise the option and to
    liquidate the underlying Futures Contract, subject to the risks of the
    availability of a liquid offset market described herein. The writer of an
    Option on a Futures Contract is subject to the risks of commodity futures
    trading, including the requirement of initial and variation margin payments,
    as well as the additional risk that movements in the price of the option may
    not correlate with movements in the price of the underlying security, index,
    currency or Futures Contract.

    RISKS OF TRANSACTIONS IN FOREIGN CURRENCIES AND OVER-THE-COUNTER DERIVATIVES
    AND OTHER TRANSACTIONS NOT CONDUCTED ON U.S. EXCHANGES: Transactions in
    Forward Contracts on foreign currencies, as well as futures and options on
    foreign currencies and transactions executed on foreign exchanges, are
    subject to all of the correlation, liquidity and other risks outlined above.
    In addition, however, such transactions are subject to the risk of
    governmental actions affecting trading in or the prices of currencies
    underlying such contracts, which could restrict or eliminate trading and
    could have a substantial adverse effect on the value of positions held by
    the Fund. Further, the value of such positions could be adversely affected
    by a number of other complex political and economic factors applicable to
    the countries issuing the underlying currencies.

      Further, unlike trading in most other types of instruments, there is no
    systematic reporting of last sale information with respect to the foreign
    currencies underlying contracts thereon. As a result, the available
    information on which trading systems will be based may not be as complete as
    the comparable data on which the Fund makes investment and trading decisions
    in connection with other transactions. Moreover, because the foreign
    currency market is a global, 24-hour market, events could occur in that
    market which will not be reflected in the forward, futures or options market
    until the following day, thereby making it more difficult for the Fund to
    respond to such events in a timely manner.

      Settlements of exercises of over-the-counter Forward Contracts or foreign
    currency options generally must occur within the country issuing the
    underlying currency, which in turn requires traders to accept or make
    delivery of such currencies in conformity with any U.S. or foreign
    restrictions and regulations regarding the maintenance of foreign banking
    relationships, fees, taxes or other charges.

      Unlike transactions entered into by the Fund in Futures Contracts and
    exchange-traded options, options on foreign currencies, Forward Contracts,
    over-the-counter options on securities, swaps and other over-the-counter
    derivatives are not traded on contract markets regulated by the CFTC or
    (with the exception of certain foreign currency options) the SEC. To the
    contrary, such instruments are traded through financial institutions acting
    as market-makers, although foreign currency options are also traded on
    certain national securities exchanges, such as the Philadelphia Stock
    Exchange and the Chicago Board Options Exchange, subject to SEC regulation.
    In an over-the-counter trading environment, many of the protections afforded
    to exchange participants will not be available. For example, there are no
    daily price fluctuation limits, and adverse market movements could therefore
    continue to an unlimited extent over a period of time. Although the
    purchaser of an option cannot lose more than the amount of the premium plus
    related transaction costs, this entire amount could be lost. Moreover, the
    option writer and a trader of Forward Contracts could lose amounts
    substantially in excess of their initial investments, due to the margin and
    collateral requirements associated with such positions.

      In addition, over-the-counter transactions can only be entered into with a
    financial institution willing to take the opposite side, as principal, of
    the Fund's position unless the institution acts as broker and is able to
    find another counterparty willing to enter into the transaction with the
    Fund. Where no such counterparty is available, it will not be possible to
    enter into a desired transaction. There also may be no liquid secondary
    market in the trading of over-the-counter contracts, and the Fund could be
    required to retain options purchased or written, or Forward Contracts or
    swaps entered into, until exercise, expiration or maturity. This in turn
    could limit the Fund's ability to profit from open positions or to reduce
    losses experienced, and could result in greater losses.

      Further, over-the-counter transactions are not subject to the guarantee of
    an exchange clearinghouse, and the Fund will therefore be subject to the
    risk of default by, or the bankruptcy of, the financial institution serving
    as its counterparty. One or more of such institutions also may decide to
    discontinue their role as market-makers in a particular currency or
    security, thereby restricting the Fund's ability to enter into desired
    hedging transactions. The Fund will enter into an over-the-counter
    transaction only with parties whose creditworthiness has been reviewed and
    found satisfactory by the Adviser.

      Options on securities, options on stock indices, Futures Contracts,
    Options on Futures Contracts and options on foreign currencies may be traded
    on exchanges located in foreign countries. Such transactions may not be
    conducted in the same manner as those entered into on U.S. exchanges, and
    may be subject to different margin, exercise, settlement or expiration
    procedures. As a result, many of the risks of over-the-counter trading may
    be present in connection with such transactions.

      Options on foreign currencies traded on national securities exchanges are
    within the jurisdiction of the SEC, as are other securities traded on such
    exchanges. As a result, many of the protections provided to traders on
    organized exchanges will be available with respect to such transactions. In
    particular, all foreign currency option positions entered into on a national
    securities exchange are cleared and guaranteed by the Options Clearing
    Corporation (the "OCC"), thereby reducing the risk of counterparty default.
    Further, a liquid secondary market in options traded on a national
    securities exchange may be more readily available than in the
    over-the-counter market, potentially permitting the Fund to liquidate open
    positions at a profit prior to exercise or expiration, or to limit losses in
    the event of adverse market movements.

      The purchase and sale of exchange-traded foreign currency options,
    however, is subject to the risks of the availability of a liquid secondary
    market described above, as well as the risks regarding adverse market
    movements, margining of options written, the nature of the foreign currency
    market, possible intervention by governmental authorities and the effects of
    other political and economic events. In addition, exchange-traded options on
    foreign currencies involve certain risks not presented by the
    over-the-counter market. For example, exercise and settlement of such
    options must be made exclusively through the OCC, which has established
    banking relationships in applicable foreign countries for this purpose. As a
    result, the OCC may, if it determines that foreign governmental restrictions
    or taxes would prevent the orderly settlement of foreign currency option
    exercises, or would result in undue burdens on the OCC or its clearing
    member, impose special procedures on exercise and settlement, such as
    technical changes in the mechanics of delivery of currency, the fixing of
    dollar settlement prices or prohibitions on exercise.

    POLICIES ON THE USE OF FUTURES AND OPTIONS ON FUTURES CONTRACTS: In order to
    assure that the Fund will not be deemed to be a "commodity pool" for
    purposes of the Commodity Exchange Act, regulations of the CFTC require that
    the Fund enter into transactions in Futures Contracts, Options on Futures
    Contracts and Options on Foreign Currencies traded on a CFTC- regulated
    exchange only (i) for bona fide hedging purposes (as defined in CFTC
    regulations), or (ii) for non-bona fide hedging purposes, provided that the
    aggregate initial margin and premiums required to establish such non-bona
    fide hedging positions does not exceed 5% of the liquidation value of the
    Fund's assets, after taking into account unrealized profits and unrealized
    losses on any such contracts the Fund has entered into, and excluding, in
    computing such 5%, the in-the-money amount with respect to an option that is
    in-the-money at the time of purchase.

  PART II - APPENDIX D
  --------------------

                           DESCRIPTION OF BOND RATINGS

    The ratings of Moody's, S&P and Fitch represent their opinions as to the
    quality of various debt instruments. It should be emphasized, however, that
    ratings are not absolute standards of quality. Consequently, debt
    instruments with the same maturity, coupon and rating may have different
    yields while debt instruments of the same maturity and coupon with different
    ratings may have the same yield.

                         MOODY'S INVESTORS SERVICE, INC.

    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 edged." Interest payments are protected by a large or by an
    exceptionally stable margin and principal is secure. While the various
    protective elements are likely to change, such changes as can be visualized
    are most unlikely to impair the fundamentally strong position of such
    issues.

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

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

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

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

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

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

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

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


                        STANDARD & POOR'S RATINGS SERVICES

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


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

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

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

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

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

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

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

    CC: An obligation rated CC is CURRENTLY HIGHLY VULNERABLE to nonpayment.


    C: 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 has
    been taken, but payments on this obligation are being continued. A C rating
    will also be assigned to a preferred stock issue in arrears on dividends or
    sinking fund payments, but that is currently paying.


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

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

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

                                    FITCH IBCA

    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.

    Speculative Grade

    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.

    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 expected recoveries in the range of 50% - 90% and D
    the lowest recovery potential, i.e. below 50%.


                         DUFF & PHELPS CREDIT RATING CO.

    AAA: Highest credit quality. The risk factors are negligible, being only
    slightly more than for risk-free U.S. Treasury debt.

    AA+, AA, AA-: High credit quality. Protection factors are strong. Risk is
    modest but may vary slightly from time to time because of economic
    conditions.

    A+, A, A-: Protection factors are average but adequate. However, risk
    factors are more variable and greater in periods of economic stress.

    BBB+, BBB, BBB-: Below-average protection factors but still considered
    sufficient for prudent investment. Considerable variability in risk during
    economic cycles.

    BB+, BB, BB-: Below investment grade but deemed likely to meet obligations
    when due. Present or prospective financial protection factors fluctuate
    according to industry conditions or company fortunes. Overall quality may
    move up or down frequently within this category.

    B+, B, B-: Below investment grade and possessing risk that obligations will
    not be met when due. Financial protection factors will fluctuate widely
    according to economic cycles, industry conditions and/or company fortunes.
    Potential exists for frequent changes in the rating within this category or
    into a higher or lower rating grade.


    CCC: Well below investment grade securities. Considerable uncertainty exists
    as to timely payment of principal, interest or preferred dividends.
    Protection factors are narrow and risk can be substantial with unfavorable
    economic/industry conditions, and/or with unfavorable company developments.

    DD: Defaulted debt obligations. Issuer failed to meet scheduled principal
    and/or interest payments.


    DP: Preferred stock with dividend arrearages.

program and shall determine from time to time what securities shall be
purchased, sold or exchanged and what portion of the assets of the Fund shall be
held uninvested, subject always to the restrictions of the Trust's Amended and
Restated Declaration of Trust, dated December 14, 1994, and By-Laws, each as
amended from time to time (respectively, the "Declaration" and the "By-Laws"),
to the provisions of the Investment Company Act of 1940 and the Rules,
Regulations and orders thereunder and to the Fund's then-current Prospectus and
Statement of Additional Information. The Adviser shall also make recommendations
as to the manner in which voting rights, rights to consent to corporate action
and any other rights pertaining to the Fund's portfolio securities shall be
exercised. Should the Trustees at any time, however, make any definite
determination as to the investment policy and notify the Adviser thereof in
writing, the Adviser shall be bound by such determination for the period, if
any, specified in such notice or until similarly notified that such
determination shall be revoked. The Adviser shall take, on behalf of the Fund,
all actions which it deems necessary to implement the investment policies
determined as provided above, and in particular to place all orders for the
purchase or sale of portfolio securities for the Fund's account with brokers or
dealers selected by it, and to that end, the Adviser is authorized as the agent
of the Fund to give instructions to the Custodian of the Fund as to the
deliveries of securities and payments of cash for the account of the Fund. In
connection with the selection of such brokers or dealers and the placing of such
orders, the Adviser is directed to seek for the Fund execution at the most
reasonable price by responsible brokerage firms at reasonably competitive
commission rates. In fulfilling this requirement, the Adviser shall not be
deemed to have acted unlawfully or to have breached any duty, created by this
Agreement or otherwise, solely by reason of its having caused the Fund to pay a
broker or dealer an amount of commission for effecting a securities transaction
in excess of the amount of commission another broker or dealer would have
charged for effecting that transaction, if the Adviser determined in good faith
that such amount of commission was reasonable in relation to the value of the
brokerage and research services provided by such broker or dealer, viewed in
terms of either that particular transaction or the Adviser's overall
responsibilities with respect to the Fund and to other clients of the Adviser as
to which the Adviser exercises investment discretion.

The Adviser may from time to time enter into sub-investment advisory agreements
with one or more investment advisers with such terms and conditions as the
Adviser may determine, provided that such sub-investment advisory agreements
have been approved in accordance with applicable provisions of the Investment
Company Act of 1940. Subject to the provisions of Article 6, the Adviser shall
not be liable for any error of judgment or mistake of law by any sub-adviser or
for any loss arising out of any investment made by any sub-adviser or for any
act or omission in the execution and management of the Fund by any sub-adviser.

      ARTICLE 2. ALLOCATION OF CHARGES AND EXPENSES. The Adviser shall furnish
at its own expense investment advisory and administrative services, office
space, equipment and clerical personnel necessary for servicing the investments
of the Fund and maintaining its organization and investment advisory facilities
and executive and supervisory personnel for managing the investments and
effecting the portfolio transactions of the Fund. The Adviser shall arrange, if
desired by the Trust, for Directors, officers and employees of the Adviser to
serve as Trustees, officers or agents of the Trust if duly elected or appointed
to such positions and subject to their individual consent and to any limitations
imposed by law. It is understood that the Fund will pay all of its own expenses
including, without limitation, compensation of Trustees "not affiliated" with
the Adviser; governmental fees; interest charges; taxes; membership dues in the
Investment Company Institute allocable to the Fund; fees and expenses of
independent auditors, of legal counsel, and of any transfer agent, registrar or
dividend disbursing agent of the Fund; expenses of repurchasing and redeeming
shares and servicing shareholder accounts; expenses of preparing, printing and
mailing stock certificates, shareholder reports, notices, proxy statements and
reports to governmental officers and commissions; brokerage and other expenses
connected with the execution, recording and settlement of portfolio security
transactions; insurance premiums; fees and expenses of the custodian for all
services to the Fund, including safekeeping of funds and securities and
maintaining required books and accounts; expenses of calculating the net asset
value of shares of the Fund; expenses of shareholders' meetings; and expenses
relating to the issuance, registration and qualification of shares of the Fund
and the preparation, printing and mailing of prospectuses for such purposes
(except to the extent that any Distribution Agreement to which the Trust is a
party provides that another party is to pay some or all of such expenses).

      ARTICLE 3. COMPENSATION OF THE ADVISER. For the services to be rendered
and the facilities provided, the Fund shall pay to the Adviser an investment
advisory fee computed and paid annually at a rate equal 1.00% of the Fund's
average daily net assets. If the Adviser shall serve for less than the whole of
any period specified in this Article 3, the compensation to the Adviser will be
prorated.

      ARTICLE 4. SPECIAL SERVICES. Should the Trust have occasion to request the
Adviser to perform services not herein contemplated or to request the Adviser to
arrange for the services of others, the Adviser will act for the Trust on behalf
of the Fund upon request to the best of its ability, with compensation for the
Adviser's services to be agreed upon with respect to each such occasion as it
arises.

      ARTICLE 5. COVENANTS OF THE ADVISER. The Adviser agrees that it will not
deal with itself, or with the Trustees of the Trust or the Trust's distributor,
if any, as principals in making purchases or sales of securities or other
property for the account of the Fund, except as permitted by the Investment
Company Act of 1940 and the Rules, Regulations or orders thereunder, will not
take a long or short position in the shares of the Fund except as permitted by
the Declaration, and will comply with all other provisions of the Declaration
and the By-Laws and the then-current Prospectus and Statement of Additional
Information of the Fund relative to the Adviser and its Directors and officers.

      ARTICLE 6. LIMITATION OF LIABILITY OF THE ADVISER. The Adviser shall not
be liable for any error of judgment or mistake of law or for any loss arising
out of any investment or for any act or omission in the execution and management
of the Fund, except for willful misfeasance, bad faith or gross negligence in
the performance of its duties and obligations hereunder. As used in this Article
6, the term "Adviser" shall include Directors, officers and employees of the
Adviser as well as that corporation itself.

      ARTICLE 7. ACTIVITIES OF THE ADVISER. The services of the Adviser to the
Fund are not deemed to be exclusive, the Adviser being free to render investment
advisory and/or other services to others. The Adviser may permit other fund
clients to use the initials "MFS" in their names. The Fund agrees that if the
Adviser shall for any reason no longer serve as the Adviser to the Fund, the
Fund will change its name so as to delete the initials "MFS." It is understood
that the Trustees, officers and shareholders of the Trust are or may be or
become interested in the Adviser, as Directors, officers, employees, or
otherwise and that Directors, officers and employees of the Adviser are or may
become similarly interested in the Trust, and that the Adviser may be or become
interested in the Fund as a shareholder or otherwise.

      ARTICLE 8. DURATION, TERMINATION AND AMENDMENT OF THIS AGREEMENT. This
Agreement shall become effective on the date first above written and shall
govern the relations between the parties hereto thereafter, and shall remain in
force until May 30, 2002 on which date it will terminate unless its continuance
after May 30, 2002 is "specifically approved at least annually" (i) by the vote
of a majority of the Trustees of the Trust who are not "interested persons" of
the Trust or of the Adviser at a meeting specifically called for the purpose of
voting on such approval, and (ii) by the Board of Trustees of the Trust, or by
"vote of a majority of the outstanding voting securities" of the Fund.

      This Agreement may be terminated at any time without the payment of any
penalty by the Trustees or by "vote of a majority of the outstanding voting
securities" of the Fund, or by the Adviser, in each case on not more than sixty
days' nor less than thirty days' written notice to the other party. This
Agreement shall automatically terminate in the event of its "assignment".

      This Agreement may be amended only if such amendment is approved by "vote
of a majority of the outstanding voting securities" of the Fund.

      ARTICLE 9. SCOPE OF TRUST'S OBLIGATIONS. A copy of the Trust's Declaration
of Trust is on file with the Secretary of State of The Commonwealth of
Massachusetts. The Adviser acknowledges that the obligations of or arising out
of this Agreement are not binding upon any of the Trust's trustees, officers,
employees, agents or shareholders individually, but are binding solely upon the
assets and property of the Trust. If this Agreement is executed by the Trust on
behalf of one or more series of the Trust, the Adviser further acknowledges that
the assets and liabilities of each series of the Trust are separate and distinct
and that the obligations of or arising out of this Agreement are binding solely
upon the assets or property of the series on whose behalf the Trust has executed
this Agreement.

      ARTICLE 10. DEFINITIONS. The terms "specifically approved at least
annually," "vote of a majority of the outstanding voting securities,"
"assignment," "affiliated person," and "interested person," when used in this
Agreement, shall have the respective meanings specified, and shall be construed
in a manner consistent with, the Investment Company Act of 1940 and the Rules
and Regulations promulgated thereunder, subject, however, to such exemptions as
may be granted by the Securities and Exchange Commission under said Act.

      ARTICLE 11. RECORD KEEPING. The Adviser will maintain records in a form
acceptable to the Trust and in compliance with the rules and regulations of the
Securities and Exchange Commission, including but not limited to records
required to be maintained by Section 31(a) of the Investment Company Act of 1940
and the rules thereunder, which at all times will be the property of the Trust
and will be available for inspection and use by the Trust.

                        INVESTMENT ADVISORY AGREEMENT


      INVESTMENT ADVISORY AGREEMENT, dated this 31st day of May, 2000, by and
between MFS SERIES TRUST I, a Massachusetts business trust (the "Trust"), on
behalf of MFS GLOBAL TELECOMMUNICATIONS FUND, a series of the Trust (the
"Fund"), and MASSACHUSETTS FINANCIAL SERVICES COMPANY, a Delaware corporation
(the "Adviser").

                                 WITNESSETH:

      WHEREAS, the Trust is engaged in business as an open-end investment
company registered under the Investment Company Act of 1940; and

      WHEREAS,  the  Adviser is willing to provide  business  services  to the
Fund on the terms and conditions hereinafter set forth;

      NOW, THEREFORE, in consideration of the mutual covenants and agreements of
the parties hereto as herein set forth, the parties covenant and agree as
follows:

      ARTICLE 1. DUTIES OF THE ADVISER. The Adviser shall provide the Fund with
such investment advice and supervision as the latter may from time to time
consider necessary for the proper supervision of its funds. The Adviser shall
act as Adviser to the Fund and as such shall furnish continuously an investment
program and shall determine from time to time what securities shall be
purchased, sold or exchanged and what portion of the assets of the Fund shall be
held uninvested, subject always to the restrictions of the Trust's Amended and

amended from time to time (respectively, the "Declaration" and the "By-Laws"),
to the provisions of the Investment Company Act of 1940 and the Rules,
Regulations and orders thereunder and to the Fund's then-current Prospectus and
Statement of Additional Information. The Adviser shall also make recommendations
as to the manner in which voting rights, rights to consent to corporate action
and any other rights pertaining to the Fund's portfolio securities shall be
exercised. Should the Trustees at any time, however, make any definite
determination as to the investment policy and notify the Adviser thereof in
writing, the Adviser shall be bound by such determination for the period, if
any, specified in such notice or until similarly notified that such
determination shall be revoked. The Adviser shall take, on behalf of the Fund,
all actions which it deems necessary to implement the investment policies

The Adviser may from time to time enter into sub-investment advisory agreements
with one or more investment advisers with such terms and conditions as the
Adviser may determine, provided that such sub-investment advisory agreements
have been approved in accordance with applicable provisions of the Investment
Company Act of 1940. Subject to the provisions of Article 6, the Adviser shall
not be liable for any error of judgment or mistake of law by any sub-adviser or
for any loss arising out of any investment made by any sub-adviser or for any

MFS(R) Series Trust I
500 Boylston Street
Boston, MA  02116

Ladies and Gentlemen:

      I am a Senior Vice President and Associate General Counsel of
Massachusetts Financial Services Company, which serves as investment adviser to
MFS Series Trust I (the "Trust"), and the Assistant Secretary of the Trust. I am
admitted to practice law in The Commonwealth of Massachusetts. The Trust was
created under a written Declaration of Trust dated July 22, 1986, executed and
delivered in Boston, Massachusetts (the "Declaration of Trust"). The beneficial
interest thereunder is represented by transferable shares without par value. The
Trustees have the powers set forth in the Declaration of Trust, subject to the
terms, provisions and conditions therein provided.

      I am of the opinion that the legal requirements have been complied with in
the creation of the Trust, and that said Declaration of Trust is legal and
valid.

      Under Article III, Section 3.4 and Article VI, Section 6.4 of the
Declaration of Trust, the Trustees are empowered, in their discretion, from time
to time to issue shares of the Trust for such amount and type of consideration,
at such time or times and on such terms as the Trustees may deem best. Under
Article VI, Section 6.1, it is provided that the number of shares of beneficial
interest authorized to be issued under the Declaration of Trust is unlimited.

      By vote adopted on February 2, 1995, the Trustees of the Trust determined
to sell to the public the authorized but unissued shares of beneficial interest
of the Trust for cash at a price which will net the Trust (before taxes) not
less than the net asset value thereof, as defined in the Trust's By-Laws,
determined next after the sale is made or at some later time after such sale.

MFS Series Trust I

March 13, 2000

      The Trust has registered an indefinite number of shares of beneficial
interest under the Securities Act of 1933.

      I am of the opinion that all necessary Trust action precedent to the issue
of all the authorized but unissued shares of beneficial interest of the Trust,
including the Shares, has been duly taken, and that all the Shares were legally
and validly issued, and when sold, will be fully paid and non-assessable,
assuming the receipt by the Trust of the cash consideration therefore in
accordance with the terms of the February 2, 1995 vote of the Trustees,
described above, except as described below. I express no opinion as to
compliance with the Securities Act of 1933, the Investment Company Act of 1940,
or applicable state "Blue Sky" or securities laws in connection with the sale of
the Shares.

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

      I consent to your filing this opinion with the Securities and Exchange
Commission.


                                              Very truly yours,

                                              JAMES R. BORDEWICK, JR.
                                              James R. Bordewick, Jr.

                                                           EXHIBIT NO. 99.13(b)

                                  MFS FUNDS
           AMENDED AND RESTATED MASTER DISTRIBUTION PLAN PURSUANT TO
                              RULE 12B-1 UNDER THE
                        INVESTMENT COMPANY ACT OF 1940

                          Effective January 1, 1997,
                    Amended and Restated December 8, 1999

      This Distribution Plan (the "Plan") has been adopted by each of the
registered investment companies identified from time to time on Exhibit A hereto
(the "Trust" or "Trusts"), severally and not jointly, pursuant to Rule 12b-1
under the Investment Company Act of 1940, as amended (the "1940 Act"), and sets
forth the material aspects of the financing of the distribution of the classes
of shares representing interests in the same portfolio issued by the Trusts.

                                 WITNESSETH:

WHEREAS, each Trust is engaged in business as an open-end management investment
company and is registered under the 1940 Act, some consisting of multiple
investment portfolios or series, each of which has separate investment
objectives and policies and segregated assets (the "Fund" or "Funds"); and

WHEREAS, each Fund intends to distribute its Shares of Beneficial Interest
(without par value) ("Shares") in accordance with Rule 12b-1 under the 1940 Act,
and desires to adopt this Distribution Plan as a plan of distribution pursuant
to such Rule; and

WHEREAS, each Fund presently offers multiple classes of Shares, some Funds
presently offering only certain classes of Shares to investors;

WHEREAS, each Trust has entered into a distribution agreement (the "Distribution
Agreement") in a form approved by the Board of Trustees of each Trust (the
"Board of Trustees") in the manner specified in Rule 12b-1, with MFS Fund
Distributors, Inc., a Delaware corporation, as distributor (the "Distributor"),
whereby the Distributor provides facilities and personnel and renders services
to each Fund in connection with the offering and distribution of Shares; and

WHEREAS, each Trust recognizes and agrees that the Distributor may retain the
services of firms or individuals to act as dealers (the "Dealers") of the Shares
in connection with the offering of Shares; and

WHEREAS, the Distribution Agreement provides that: (a) a sales charge may be
paid by investors who purchase certain classes of Shares (i.e., Class A shares
and Class J shares) and that the Distributor and Dealers will receive such sales
charge as partial compensation for their services in connection with the sale of
these classes of Shares, and (b) the Distributor may (but is not required to)
impose certain deferred sales charges in connection with the repurchase of
Shares and the Distributor may retain or receive from a fund, as the case may
be, all such deferred sales charges; and

WHEREAS, the Board of Trustees of each Trust, in considering whether each Fund
should adopt and implement this Plan, has evaluated such information as it
deemed necessary to an informed determination as to whether this Plan should be
adopted and implemented and has considered such pertinent factors as it deemed
necessary to form the basis for a decision to use assets of a Fund for such
purposes, and has determined that there is a reasonable likelihood that the
adoption and implementation of this Plan will benefit the Fund and its
shareholders; and

NOW THEREFORE, the Board of Trustees of each Trust hereby adopts this Plan for
each Fund as a plan of distribution in accordance with Rule 12b-1, relating to
the classes of Shares each Fund from time to time offers, on the following terms
and conditions:

1.    SERVICES PROVIDED AND EXPENSES BORNE BY DISTRIBUTOR.

      1.1.  As specified in the Distribution Agreement, the Distributor shall
            provide facilities, personnel and a program with respect to the
            offering and sale of Shares. Among other things, the Distributor
            shall be responsible for any commissions payable to Dealers
            (including any ongoing maintenance commissions), all expenses of
            printing (excluding typesetting) and distributing prospectuses to
            prospective shareholders and providing such other related services
            as are reasonably necessary in connection therewith.

      1.2.  The Distributor shall bear all distribution-related expenses to the
            extent specified in the Distribution Agreement in providing the
            services described in Section 1.1, including, without limitation,
            the compensation of personnel necessary to provide such services and
            all costs of travel, office expenses (including rent and overhead),
            equipment, printing, delivery and mailing costs.

2.    DISTRIBUTION FEES AND SERVICE FEES.

      2.1   Distribution and Service Fees Common to Each Class of Shares.

            2.1.1. Service Fees. As partial consideration for the personal
            services and/or account maintenance services performed by each
            Dealer in the performance of its obligations under its dealer
            agreement with the Distributor, each Fund shall pay each Dealer a
            service fee periodically at a rate not to exceed 0.25% per annum of
            the portion of the average daily net assets of the Fund that is
            represented by the Class of Shares that are owned by investors for
            whom such Dealer is the holder or dealer of record. That portion of
            the Fund's average daily net assets on which the fees payable under
            this Section 2.1.1. hereof are calculated may be subject to certain
            minimum amount requirements as may be determined, and additional or
            different dealer qualification standards that may be established,
            from time to time, by the Distributor. The Distributor shall be
            entitled to be paid any fees payable under this Section 2.1.1.
            hereof with respect to Shares for which no Dealer of record exists
            or qualification standards have not been met as partial
            consideration for personal services and/or account maintenance
            services provided by the Distributor to those Shares. The service
            fee payable pursuant to this Section 2.1.1. may from time to time be
            paid by a Fund to the Distributor and the Distributor will then pay
            these fees to Dealers on behalf of the Fund or retain them in
            accordance with this paragraph.

            2.1.2. Distribution Fees. As partial consideration for the services
            performed as specified in the Distribution Agreement and expenses
            incurred in the performance of its obligations under the
            Distribution Agreement, a Fund shall pay the Distributor a
            distribution fee periodically at a rate based on the average daily
            net assets of a Fund attributable to the designated Class of Shares.
            The amount of the distribution fee paid by the Fund differs with
            respect to each Class of Shares, as does the use by the Distributor
            of such distribution fees.

      2.2.  Distribution Fees Relating to Class A Shares

            2.2.1. It is understood that the Distributor may impose certain
            deferred sales charges in connection with the repurchase of Class A
            Shares by a Fund and the Distributor may retain (or receive from the
            Fund, as the case may be) all such deferred sales charges. Each Fund
            listed on Exhibit B hereto shall pay the Distributor a distribution
            fee periodically at a rate of 0.10% per annum of average daily net
            assets of the Fund attributable to Class A Shares. Each Fund listed
            on Exhibit C hereto shall pay the Distributor a distribution fee
            periodically at a rate not to exceed 0.25% per annum of average
            daily net assets of the Fund attributable to Class A Shares. Such
            payments shall commence following shareholder approval of the Plan
            but only upon notification by the Distributor to the Fund of the
            commencement of the Plan (the "Commencement Date").

            2.2.2. The aggregate amount of fees and expenses paid pursuant to
            Sections 2.1. and 2.2. hereof shall not exceed 0.35% per annum and
            0.50% per annum of the average daily net assets attributable to
            Class A Shares of each Fund listed on Exhibit B hereto and Exhibit
            C, hereto, respectively. No fees shall be paid pursuant to Section
            2.2.1. hereof or this Section 2.2.2. to any insurance company which
            has entered into an agreement with the Trust on behalf of a Fund and
            the Distributor that permits such insurance company to purchase
            Class A Shares from a Fund at their net asset value in connection
            with annuity agreements issued in connection with the insurance
            company's separate accounts.

      2.3.  Distribution Fees Relating to Class B Shares

            2.3.1. It is understood that the Distributor may impose certain
            deferred sales charges in connection with the repurchase of Class B
            Shares by a Fund and the Distributor may retain (or receive from the
            Fund, as the case may be) all such deferred sales charges. As
            additional consideration for all services performed and expenses
            incurred in the performance of its obligations under the
            Distribution Agreement relating to Class B Shares, a Fund shall pay
            the Distributor a distribution fee periodically at a rate not to
            exceed 0.75% per annum of the Fund's average daily net assets
            attributable to Class B Shares.

            2.3.2. Each Fund understands that agreements between the Distributor
            and the Dealers may provide for payment of commissions to Dealers in
            connection with the sale of Class B Shares and may provide for a
            portion (which may be all or substantially all) of the fees payable
            by a Fund to the Distributor under the Distribution Agreement to be
            paid by the Distributor to the Dealers in consideration of the
            Dealer's services as a dealer of the Class B Shares. Except as
            described in Section 2.1., nothing in this Plan shall be construed
            as requiring a Fund to make any payment to any Dealer or to have any
            obligations to any Dealer in connection with services as a dealer of
            Class B Shares. The Distributor shall agree and undertake that any
            agreement entered into between the Distributor and any Dealer shall
            provide that, except as provided in Section 2.1., such Dealer shall
            look solely to the Distributor for compensation for its services
            thereunder and that in no event shall such Dealer seek any payment
            from the Fund.

      2.4.  Distribution Fees Relating to Class C Shares

            2.4.1. It is understood that the Distributor may (but is not
            required to) impose certain deferred sales charges in connection
            with the repurchase of Class C Shares by a Fund and the Distributor
            may retain (or receive from the Fund, as the case may be) all such
            deferred sales charges. As additional consideration for all services
            performed and expenses incurred in the performance of its
            obligations under the Distribution Agreement relating to Class C
            Shares, a Fund shall pay the Distributor a distribution fee
            periodically at a rate not to exceed 0.75% per annum of the Fund's
            average daily net assets attributable to Class C Shares.

            2.4.2. Each Fund understands that agreements between the Distributor
            and the Dealers may provide for payment of commissions to Dealers in
            connection with the sales of Class C Shares and may provide for a
            portion (which may be all or substantially all) of the fees payable
            by a Fund to the Distributor under the Distribution Agreement to be
            paid to the Dealers in consideration of the Dealer's services as a
            dealer of the Class C Shares. Except as described in Section 2.1.,
            nothing in this Plan shall be construed as requiring a Fund to make
            any payment to any Dealer or to have any obligations to any Dealer
            in connection with services as a dealer of Class C Shares. The
            Distributor shall agree and undertake that any agreement entered
            into between the Distributor and any Dealer shall provide that,
            except as provided in Section 2.1., such Dealer shall look solely to
            the Distributor for compensation for its services thereunder and
            that in no event shall such Dealer seek any payment from the Fund.

      2.5.  Distribution Fees Relating to Class J Shares

            2.5.1. It is understood that the Distributor may (but is not
            required to) impose certain deferred sales charges in connection
            with the repurchase of Class J Shares by a Fund and the Distributor
            may retain (or receive from the Fund, as the case may be) all such
            deferred sales charges. As additional consideration for all services
            performed and expenses incurred in the performance of its
            obligations under the Distribution Agreement relating to Class J
            Shares, a Fund shall pay the Distributor a distribution fee
            periodically at a rate not to exceed 0.50% (in the case of the MFS
            Emerging Growth Fund), 0.70% (in the case of the MFS Global Equity
            Fund) or 0.75% (in the case of the MFS Strategic Growth Fund) per
            annum of the Fund's average daily net assets attributable to Class J
            Shares.

            2.5.2. Each Fund understands that agreements between the Distributor
            and the Dealers may provide for payment of commissions to Dealers in
            connection with the sale of Class J Shares and may provide for a
            portion (which may be all or substantially all) of the fees payable
            by a Fund to the Distributor under the Distribution Agreement to be
            paid by the Distributor to the Dealers in consideration of the
            Dealer's services as a dealer of the Class J Shares. Except as
            described in Section 2.1., nothing in this Plan shall be construed
            as requiring a Fund to make any payment to any Dealer or to have any
            obligations to any Dealer in connection with services as a dealer of
            Class J Shares. The Distributor shall agree and undertake that any
            agreement entered into between the Distributor and any Dealer shall
            provide that, except as provided in Section 2.1., such Dealer shall
            look solely to the Distributor for compensation for its services
            thereunder and that in no event shall such Dealer seek any payment
            from the Fund.

3.    EXPENSES BORNE BY FUND. Each Fund shall pay all fees and expenses of any
      independent auditor, legal counsel, investment adviser, administrator,
      transfer agent, custodian, shareholder servicing agent, registrar or
      dividend disbursing agent of the Fund; expenses of distributing and
      redeeming Shares and servicing shareholder accounts; expenses of
      preparing, printing and mailing prospectuses, shareholder reports,
      notices, proxy statements and reports to governmental officers and
      commissions and to shareholders of a Fund, except that the Distributor
      shall be responsible for the distribution-related expenses as provided in
      Section 1 hereof.

4.    ACTION TAKEN BY THE TRUST. Nothing herein contained shall be deemed to
      require a Trust to take any action contrary to its Declaration of Trust or
      By-laws or any applicable statutory or regulatory requirement to which it
      is subject or by which it is bound, or to relieve or deprive the Board of
      Trustees of the responsibility for and control of the conduct of the
      affairs of a Fund.

5.    EFFECTIVENESS OF PLAN. This Plan shall become effective upon (a) approval
      by a vote of at least a "majority of the outstanding voting securities" of
      each particular class of Shares (unless previously so approved), and (b)
      approval by a vote of the Board of Trustees and a vote of a majority of
      the Trustees who are not "interested persons" of the Trust and who have no
      direct or indirect financial interest in the operation of the Plan or in
      any agreement related to the Plan (the "Qualified Trustees"), such votes
      to be cast in person at a meeting called for the purpose of voting on this
      Plan.

6.    DURATION OF PLAN. This Plan shall continue in effect indefinitely;
      provided however, that such continuance is "specifically approved at least
      annually" by vote of both a majority of the Trustees of the Trust and a
      majority of the Qualified Trustees, such votes to be cast in person at a
      meeting called for the purpose of voting on the continuance of this Plan.
      If such annual approval is not obtained, this Plan, with respect to the
      classes of Shares with respect to which such approval was not obtained,
      shall expire 12 months after the effective date of the last approval.

7.    AMENDMENTS OF PLAN. This Plan may be amended at any time by the Board of
      Trustees; provided that this Plan may not be amended to increase
      materially the amount of permitted expenses hereunder without the approval
      of holders of a "majority of the outstanding voting securities" of the
      affected Class of Shares and may not be materially amended in any case
      without a vote of a majority of both the Trustees and the Qualified
      Trustees. This Plan may be terminated at any time by a vote of a majority
      of the Qualified Trustees or by a vote of the holders of a "majority of
      the outstanding voting securities" of Shares.

8.    REVIEW BY BOARD OF TRUSTEES. Each Fund and the Distributor shall provide
      the Board of Trustees, and the Board of Trustees shall review, at least
      quarterly, a written report of the amounts expended under this Plan and
      the purposes for which such expenditures were made.

9.    SELECTION AND NOMINATION OF QUALIFIED TRUSTEES. While this Plan is in
      effect, the selection and nomination of Qualified Trustees shall be
      committed to the discretion of the Trustees who are not "interested
      persons" of the Trust.

10.   DEFINITIONS; COMPUTATION OF FEES. For the purposes of this Plan, the terms
      "interested persons", "majority of the outstanding voting securities" and
      "specifically approved at least annually" are used as defined in the 1940
      Act or the rules and regulations adopted thereunder. All references herein
      to "Fund" shall be deemed to refer to a Trust where such Trust does not
      have multiple portfolios or series. In addition, for purposes of
      determining the fees payable to the Distributor hereunder, (i) the value
      of a Fund's net assets shall be computed in the manner specified in each
      Fund's then-current prospectus and statement of additional information for
      computation of the net asset value of Shares of the Fund and (ii) the net
      asset value per Share of a particular class shall reflect any plan adopted
      under Rule 18f-3 under the 1940 Act.

11.   RETENTION OF PLAN RECORDS. Each Trust shall preserve copies of this Plan,
      and each agreement related hereto and each report referred to in Section
      8.1 hereof (collectively, the "Records") for a period of six years from
      the end of the fiscal year in which such Record was made and each such
      record shall be kept in an easily accessible place for the first two years
      of said record-keeping.

12.   APPLICABLE LAW. This Plan shall be construed in accordance with the laws
      of The Commonwealth of Massachusetts and the applicable provisions of the
      1940 Act.

13.   SEVERABILITY OF PLAN. If any provision of this Plan shall be held or made
      invalid by a court decision, statute, rule or otherwise, the remainder of
      the Plan shall not be affected thereby. The provisions of this Plan are
      severable with respect to each Class of Shares offered by a Fund and with
      respect to each Fund.

14.   SCOPE OF TRUST'S OBLIGATION. A copy of the Declaration of Trust of each
      Trust is on file with the Secretary of State of The Commonwealth of
      Massachusetts. It is acknowledged that the obligations of or arising out
      of this Plan are not binding upon any of the Trust's trustees, officers,
      employees, agents or shareholders individually, but are binding solely
      upon the assets and property of the Trust in accordance with its
      proportionate interest hereunder. If this Plan is adopted by the Trust on
      behalf of one or more series of the Trust, it is further acknowledged that
      the assets and liabilities of each series of the Trust are separate and
      distinct and that the obligations of or arising out of this Plan are
      binding solely upon the assets or property of the series on whose behalf
      the Trust has adopted this Plan. If the Trust has adopted this Plan on
      behalf of more than one series of the Trust, it is also acknowledged that
      the obligations of each series hereunder shall be several and not joint,
      in accordance with its proportionate interest hereunder, and no series
      shall be responsible for the obligations of another series.

                                    MFS FUNDS
          AMENDED AND RESTATED PLAN PURSUANT TO RULE 18F-3(D) UNDER THE
                         INVESTMENT COMPANY ACT OF 1940

   Effective September 6, 1996, as amended and restated May 27, 1998 (Crimson
                                   Board) and
                            June 17, 1998 (Red Board)

      This Plan relating to Multiple Classes of Shares (the "Plan") has been
adopted by each of the registered investment companies (the "Trust" or
"Trusts"), identified on behalf of its various series from time to time on
Exhibit A hereto, severally and not jointly, pursuant to Rule 18f-3(d) under the
Investment Company Act of 1940, as amended (the "1940 Act"), and sets forth the
differences in expenses among the classes of shares representing interests in
the same portfolio issued by the Trusts under a multiple distribution
arrangement and the conversion and exchange feature, if any, of each such class
of shares (the "Multiple Distribution System").

A.    THE TRUSTS AND FUNDS

      Each Trust is an open-end management investment company registered under
      the 1940 Act, some consisting of multiple investment portfolios or series,
      each of which has separate investment objectives and policies and
      segregated assets (the "Fund" or "Funds").

      Each Trust (if it has no series) and each Trust on behalf of each Fund (if
      it has series) has entered into an investment advisory agreement with
      Massachusetts Financial Services Company or an affiliate thereof ("MFS")
      pursuant to which MFS, subject to the general supervision of the Board of
      Trustees of the Trust, provides portfolio management services. Each Trust
      has also entered into an administrative services agreement with MFS
      pursuant to which MFS provides financial operations, legal and other
      administrative services to each Fund. Each Trust has also entered into a
      distribution agreement with MFS Fund Distributors, Inc. ("MFD") to provide
      certain distribution services for the Fund, pursuant to which MFD acts as
      each Fund's distributor. Certain Funds have adopted a distribution plan (a
      "Rule 12b-1 Plan") in accordance with Rule 12b-1 under the 1940 Act.
      Transfer agency and recordkeeping functions are provided to each Fund by
      MFS Service Center, Inc. ("MFSC") pursuant to a shareholder servicing
      agent agreement.

B.    THE MULTIPLE DISTRIBUTION SYSTEM

      Under the Multiple Distribution System, each Fund may provide investors
      with the option of purchasing shares either (1) with a front-end sales
      load (except sales of $1 million or more and purchases by certain
      retirement plans, which are subject to a contingent deferred sales charge
      ("CDSC")) which may vary among Funds and, in some cases, a distribution
      fee and/or service fee pursuant to a Rule 12b-1 Plan ("Class A shares") or
      (2) without a front-end sales load, but subject to a CDSC as well as a
      distribution fee and/or a service fee pursuant to a Rule 12b-1 Plan
      ("Class B shares") or (3) without a front-end load, but subject to a CDSC,
      (which may differ from the CDSC applicable to Class B shares) as well as a
      distribution fee and/or service fee pursuant to a Rule 12b-1 Plan ("Class
      C shares"), (4) without a front-end load or CDSC and without a
      distribution or service fee pursuant to a Rule 12b-1 plan ("Class I
      shares") or (5) with a lower front-end sales load than Class A shares and
      a higher distribution fee and/or service fee pursuant to a Rule 12b-1 Plan
      than Class A shares ("Class J shares"). Some of the Funds presently offer
      only certain of these classes of shares to investors. This Plan shall
      apply to the classes of shares of each Fund only to the extent each Trust
      has designated particular classes of shares for that Fund. The Funds may
      from time to time create one or more additional classes of shares, the
      terms of which may differ from the Class A shares, Class B shares, Class C
      shares, Class I shares and Class J shares described below.

      1.    Class A Shares

            Class A shares are offered to investors at net asset value plus a
            front-end sales load (except for certain sales, which are subject to
            a CDSC). The sales load is at rates competitive in the industry and
            is subject to reduction for larger purchases and under a right of
            accumulation or a letter of intention. In accordance with Section
            22(d) of the 1940 Act, the front-end sales load is waived for
            certain types of investors or in connection with certain classes of
            transactions. Class A shareholders are assessed an ongoing service
            fee and/or distribution fee under a Rule 12b-1 Plan based upon a
            percentage of the average daily net asset value of the Class A
            shares. Proceeds from the front-end load, service fee and
            distribution fee are used by MFD primarily to pay initial
            commissions, ongoing service fees and certain distribution-related
            expenses, respectively. Amounts payable under the Rule 12b-1 Plan
            are subject to such further limitations as the Trustees may from
            time to time determine and as set forth in the registration
            statement of each Trust as from time to time in effect.

      2.    Class B Shares

            Class B shares are offered to investors at net asset value without
            the imposition of a sales load at the time of purchase. However, an
            investor's proceeds from a redemption of Class B shares (on which a
            dealer commission has been paid) within a specified period of time
            after purchase may be subject to a CDSC. The CDSC is paid to and
            retained by MFD. The amount of any applicable CDSC will be based
            upon the lower of the net asset value at the time of purchase or at
            the time of redemption as required by Rule 6c-10 under the 1940 Act.
            Class B shares that are redeemed will not be subject to a CDSC to
            the extent that the shares represent (1) reinvestment of dividends
            or capital gain distributions, (2) shares redeemed after a defined
            period of time, or (3) increases in the value of an account due to
            capital appreciation. Class B shareholders are assessed a
            distribution fee and/or service fee pursuant to a Rule 12b-1 Plan.
            Class B shares that are outstanding for a specified period of time
            will convert to Class A shares of the Fund. See "Conversion
            Features" below. Amounts payable under the Rule 12b-1 Plan are
            subject to such further limitations as the Trustees may from time to
            time determine and as set forth in the registration statement of
            each Trust as from time to time in effect.

      3.    Class C Shares

            Class C shares are offered to investors at net asset value without
            the imposition of a front-end sales load. Class C shareholders are
            assessed a distribution fee and/or service fee pursuant to a Rule
            12b-1 Plan. In addition, an investor's proceeds from a redemption of
            Class C shares (on which a dealer commission has been paid) within a
            specified period of time after purchase may be subject to a CDSC.
            The CDSC is paid to and retained by MFD. Class C shares that are
            redeemed will not be subject to a CDSC to the extent that the shares
            represent (i) reinvestment of dividends or capital gains
            distributions, (ii) shares redeemed after a defined period of time,
            or (iii) increases in the value of an account due to capital
            appreciation. Class C shares differ from Class B shares in that (i)
            the Class C shares would be subject to a lower CDSC than the Class B
            shares (ii) the CDSC would be imposed on the Class C shares for a
            shorter period of time than the Class B shares and (iii) Class C
            shares do not convert to any other class of shares. Amounts payable
            under the Rule 12b-1 Plan are subject to such further limitations as
            the Trustees may from time to time determine and as set forth in the
            registration statement of each Trust as from time to time in effect.

      4.    Class I Shares

            Class I shares are offered to certain investors at net asset value
            without the imposition of a front-end load or a CDSC and without a
            distribution fee and/or service fee pursuant to a Rule 12b-1 Plan.

      5.    Class J Shares

            Class J shares are offered exclusively to investors in Japan at net
            asset value plus a front-end sales load. The sales load is at rates
            competitive for investment products offered to retail investors in
            Japan. In accordance with Section 22(d) of the 1940 Act, the
            front-end sales load may be waived for certain types of investors or
            in connection with certain classes of transactions. Class J
            shareholders are assessed an ongoing service fee and/or distribution
            fee under a Rule 12b-1 Plan based upon a percentage of the average
            daily net asset value of the Class J shares. Proceeds from the
            front-end load, service fee and distribution fee are used by MFD
            primarily to pay initial commissions, ongoing service fees and
            certain distribution-related expenses, respectively. Amounts payable
            under the Rule 12b-1 Plan are subject to such further limitations as
            the Trustees may from time to time determine and as set forth in the
            registration statement of each Trust as from time to time in effect.

C.    EXPENSES

      Under the Multiple Distribution System, all expenses incurred by a Fund
      are borne proportionately by each class of shares based on the relative
      net assets attributable to each such class, except for the (i) different
      distribution and service fees (and any other costs relating to
      implementing the Rule 12b-1 Plan or an amendment to such Plan including
      obtaining shareholder approval of the Rule 12b-1 Plan or an amendment to
      such Plan); (ii) printing and postage expenses; and (iii) shareholder
      servicing fees attributable to a class, which will be borne directly by
      each respective class.

D.    CONVERSION FEATURES

      1.    Conversion of Class B shares

            If a shareholder's Class B shares of a Fund remain outstanding for a
            specified period of time, they will automatically convert to Class A
            shares of that Fund at the relative net asset values of each of the
            classes, and will thereafter be subject to the lower fee under the
            Class A Rule 12b-1 Plan. Shares purchased through the reinvestment
            of distributions paid in respect of Class B shares will be treated
            as Class B shares for purposes of the payment of the distribution
            and service fees under the Rule 12b-1 Plan applicable to Class B
            shares. However, for purposes of conversion to Class A, all shares
            in a shareholder's account that were purchased through the
            reinvestment of distributions paid in respect of Class B shares (and
            which have not converted to Class A shares as provided above) will
            be held in a separate sub-account. Each time any Class B shares in
            the shareholder's account (other than those in the sub-account)
            convert to Class A, a portion of the Class B shares then in the
            sub-account will also convert to Class A. The portion will be
            determined by the ratio that the shareholder's Class B shares not
            acquired through distributions that are converting to Class A bears
            to the shareholder's total Class B shares not acquired through
            distributions.

      2.    Conversion of Other Classes

            Any other class of shares may provide that shares in that class (the
            "Purchase Class") will, after a period of time, automatically
            convert into another class of shares (the "Target Class") in
            accordance with the provisions of Rule 18f-3. Such a conversion
            feature would be described in the relevant Fund's prospectus.

      3.    General

            Any conversion of shares of one class to shares of another class
            would be subject to the continuing availability of a ruling of the
            Internal Revenue Service or an opinion of legal counsel to the
            effect that the conversion of these shares does not constitute a
            taxable event under federal tax law. Any such conversion may be
            suspended if such a ruling or opinion is no longer available. In the
            event such conversion does not occur, these shares would continue to
            be subject for an indefinite period to the higher distribution fees
            and, in some cases, higher shareholder servicing fees of the class.

E.    EXCHANGE FEATURES

      Each class of shares may have different exchange features applicable to
      the shares of that class. Currently, Class A shares of a Fund may be
      exchanged, either all or in part, at net asset value for Class A shares of
      another Fund. Class A shares of MFS Cash Reserve Fund may be exchanged for
      Class A shares of another Fund at net asset value plus that Fund's normal
      front-end load (except in certain situations described in MFS Cash Reserve
      Fund's prospectus). Class B shares may be exchanged, either all or in
      part, at net asset value for Class B shares of another Fund. Class C
      shares may be exchanged, either all or in part, at net asset value for
      Class C shares of another Fund. Class I shares may be exchanged, either
      all or in part, at net asset value for Class I shares of another Fund
      available for purchase by the shareholder and for shares of the MFS Money
      Market Fund. Class J shares of a Fund may be exchanged, either all or in
      part, at net asset value for Class J shares of another Fund. With respect
      to an exchange involving shares subject to a CDSC, the CDSC will be
      unaffected by the exchange and the holding period for purposes of
      calculating the CDSC will carry over to the acquired shares. Each exchange
      is subject to share availability and must involve shares having an
      aggregate minimum value as set forth in the Fund's prospectus. Shares of
      one class may not be exchanged for shares of any other class.

F.    PLAN DURATION

      This Plan shall continue in effect indefinitely unless terminated or
      amended as provided herein.

G.    TERMINATION AND AMENDMENT PROCEDURE

      This Plan may be terminated at any time by a vote of a majority of the
      Trustees who are not "interested persons" of the Trust ("Disinterested
      Trustees") or by a vote of the holders of a "majority of the outstanding
      voting securities" of the Trust. No material amendment may be made to this
      Plan without the approval of a majority of the Trustees, including a
      majority of the Disinterested Trustees, after a finding that the Plan is
      in the best interests of each class of shares individually and each Fund
      as a whole. This Plan may be amended without Trustee approval to make a
      change that is not material which includes, by way of example, to supply
      any omission, to cure, correct or supplement any ambiguous, defective or
      inconsistent provision hereof.

H.    SCOPE OF TRUST'S OBLIGATIONS

      A copy of the Declaration of Trust of each Trust is on file with the
      Secretary of State of The Commonwealth of Massachusetts. It is
      acknowledged that the obligations of or arising out of this Plan are not
      binding upon any of the Trust's trustees, officers, employees, agents or
      shareholders individually, but are binding solely upon the assets and
      property of the Trust in accordance with its proportionate interest
      hereunder. If this Plan is adopted by the Trust on behalf of one or more
      series of the Trust, it is further acknowledged that the assets and
      liabilities of each series of the Trust are separate and distinct and that
      the obligations of or arising out of this Plan are binding solely upon the
      assets or property of the series on whose behalf the Trust has adopted
      this Plan. If the Trust has adopted this Plan on behalf of more than one
      series of the Trust, it is also acknowledged that the obligations of each
      series hereunder shall be several and not joint, in accordance with its
      proportionate interest hereunder, and no series shall be responsible for
      the obligations of another series.

I.    MISCELLANEOUS PROVISIONS

      As used in this Plan, the terms "interested person" and "majority of the
      outstanding voting securities" are used as defined in the 1940 Act. This
      Plan shall be administered and construed in accordance with the laws of
      The Commonwealth of Massachusetts and the applicable provisions of the
      1940 Act and the Rules and Regulations promulgated thereunder. If any
      provision of this Plan shall be held or made invalid by a court decision,
      statute, rule or otherwise, the remainder of the Plan shall not be
      affected thereby.

                                                           EXHIBIT NO. 99.16(a)

                                     FORM OF

                                 CODE OF ETHICS

      [Name of Fund] (the "Fund") has determined to adopt this Code of Ethics
("Code") with respect to certain types of personal securities transactions by
officers and Trustees of the Fund which might be deemed to create possible
conflicts of interest and to establish reporting requirements and enforcement
procedures with respect to such transactions.

      I. Rules Applicable to Affiliated Officers and Trustees

         A. Incorporation of MFS' Code of Ethics.

            The provisions of the Statement of Policy on Personal Security
            Transactions of Massachusetts Financial Services Company [the parent
            of] the Fund's Investment adviser ("MFS") (the "MFS Code of
            Ethics"), which is attached as Appendix A hereto, are hereby
            incorporated herein as the Fund's Code of Ethics applicable to
            officers and Trustees of the Fund who are not Disinterested
            Trustees. A violation of the MFS Code of Ethics shall constitute a
            violation of the Fund's Code.

         B. Reports.

            Officers and Trustees of the Fund other than Disinterested Trustees
            shall file the reports required by the MFS Code of Ethics. Such
            filings shall be deemed a filing under this Code of Ethics and shall
            be available to the Fund upon request.

         C. Review.

            (1) Reports filed by officers and Trustees of the Fund other than
                Disinterested Trustees as required by the MFS Code of Ethics
                shall be reviewed as provided by the MFS Code of Ethics. Any
                facts that could give rise to a violation of the Code by any
                such individual shall be reported to the Secretary of the Fund.
                The Secretary of the Fund shall determine whether a violation of
                the Code may have occurred. Before making any determination that
                a violation has been committed by any person, the Secretary
                shall give such person an opportunity to supply additional
                explanatory material.

            (2) If the Secretary determines that a material violation of this
                Code has or may have occurred, he shall submit his written
                determination, together with the transaction report and any
                additional explanatory material provided by the individual, to
                the Chairman of MFS, who shall make an independent determination
                of whether a violation has occurred.

         D. Sanctions.

            If the Chairman of MFS finds that a material violation has occurred,
            he shall report the violation and any sanction imposed by MFS to the
            Trustees of the Fund. if a securities transaction of the Chairman of
            MFS is under consideration, another member of the Executive
            Committee of MFS shall act in all respects in the manner prescribed
            herein for the Chairman of MFS.

     II. Rules Application to Disinterested Trustees of the Funds.

         A. Definitions.

            (1) "Beneficial ownership" shall be interpreted in the same manner
                as it would be in determining whether a person is subject to the
                provisions of Section 16 of the Securities Exchange Act of 1934
                and the rules and regulations thereunder. Application of this
                definition is explained in more detail in Appendix B hereto.

            (2) "Control" means the power to exercise a controlling influence
                over the management or policies of a company, unless such power
                is solely the result of an official position with such company.

            (3) "Disinterested Trustee" means a Trustee of a Fund who is not an
                "Interested Person" of the Fund within the meaning of the
                Investment Company Act.

            (4) "Purchase or sale of a security" includes, among other things,
                the writing of an option to purchase or sell a security.

            (5) "Security" shall have the same meaning as that set forth in
                Section 2(a)(36) of the Investment Company Act (in effect, all
                securities) except that it shall not include securities issued
                by the Government of the United States or an agency thereof,
                bankers' acceptances, bank certificates of deposit, commercial
                paper and shares of registered open-end investment companies.

         B. Prohibited Purchases and Sales.

            No Disinterested Trustee of any of the Funds shall purchase or sell,
            directly or indirectly, any Security in which he has or by reason of
            such transaction acquires, any direct or indirect beneficial
            ownership and which to his actual knowledge at the time of such
            purchase of sale:

            (1) Is being considered for purchase or sale by the Fund.

            (2) Is being purchase or sold by the Fund.

         C. Exempted Transactions.

            The prohibitions of Section IIB of this Code shall not apply to:

            (1) Purchases or sales effected in any account over which the
                Disinterested Trustee has no direct or indirect influence or
                control.

            (2) Purchases or sales which are non-volitional on the part of
                either the Disinterested Trustee or the Fund.

            (3) Purchases which are part of an automatic dividend reinvestment
                plan.

            (4) Purchases effected upon the exercise of rights issued by an
                issuer pro rata to all holders of a class of its securities, to
                the extent such rights were acquired from such issuer, and sales
                of such rights so acquired.

            (5) Purchases or sales other than those exempted in (1) through (4)
                above which do not cause the Disinterested Trustee to gain
                improperly a personal benefit through his relationship with the
                Funds and are only remotely potentially harmful to a Fund
                because they would be very unlikely to affect a highly
                institutional market, and are previously approved by MFS' Legal
                Department, which approval shall be confirmed in writing.

         D. Reporting.

            (1) Whether or not one of the exemptions listed in IIC applies,
                every Disinterested Trustee of a Fund shall file with the
                Secretary of the Fund a report containing the information
                described in Section IID(2) of the Code with respect to
                transactions in any Security in which such Disinterested Trustee
                has, or by reason of such transaction acquires, any direct or
                indirect beneficial ownership of such Trustee, at the time of
                that transaction, knew, or in the ordinary course of fulfilling
                his official duties as a Trustee of the Fund, should have known
                that, during the 15-day period immediately preceding or after
                the date of the transaction by the Trustee:

                (a) such Security was or is to be purchased or sold by the Fund
                    or

                (b) such Security was or is being considered for purchase or
                    sale by the Fund;

                provided, however, that a Disinterested Trustee shall not be
                required to make a report with respect to transactions effected
                for any account over which such person does not have any direct
                or indirect influence or control.

            (2) Every report shall be made not later than 10 days after the end
                of the calendar quarter in which the transaction to which the
                report relates was effected, and shall contain the following
                information:

                (a) the date of the transaction, the title and the number of
                    shares, and principal amount of each Security involved;

                (b) the nature of the transaction (i.e., purchase, sale or any
                    other type of acquisition or disposition);

                (c) the price at which the transaction was effected; and

                (d) the name of the broker, dealer or bank with or through whom
                    the transaction was effected.

            (3) Every report concerning a purchase or sale prohibited under
                Section IIB hereof with respect to which the reporting person
                relies upon one of the exemptions provided in Section IIC shall
                contain a brief statement of the exemption relied upon and the
                circumstances of the transaction.

            (4) Any such report may contain a statement that the report shall
                not be construed as an admission by the person making such
                report that he has any direct or indirect beneficial ownership
                in the security to which the report relates.

         E. Review.

            (1) The Secretary of the Fund shall compare the reported personal
                securities transactions with completed and contemplated
                portfolio transactions of the Fund to determine whether any
                transaction ("Reviewable Transactions") listed in Section IIB
                (disregarding exemptions provided by Section IIC (1) through
                (5)) may have occurred.

            (2) If the Secretary determines that a Reviewable Transaction may
                have occurred, he shall submit the pertinent information
                regarding the transaction to counsel for the Disinterested
                Trustees. Such counsel shall determine whether a material
                violation of this Code may have occurred, taking into account
                all the exemptions provided under Section IIC. Before making any
                determination that a violation has occurred, such counsel shall
                give the person involved an opportunity to supply additional
                information regarding the transaction in question.

         F. Sanctions.

                  If such counsel determines that a material violation of this
                  Code has occurred, they shall so advise the Chairman or
                  President of the Fund and an ad hoc committee consisting of
                  the Disinterested Trustees of the Fund, other than the person
                  whose transaction is under consideration, and shall provide
                  the committee with a report of the matter, including any
                  additional information supplied by such person. The committee
                  may impose such sanction as it deems appropriate.

    III. Miscellaneous.

         A. Amendments to MFS' Code of Ethics.

            Any amendment to the MFS Code of Ethics shall be deemed an amendment
            to Section IA of this Code effective 30 days after written notice of
            such amendment shall have been received by the Disinterested
            Trustees of the Funds unless the Disinterested Trustees expressly
            determine that such amendment shall become effective at an earlier
            or later date or shall not be adopted.

         B. Records.

            The Funds shall maintain records in the manner and to the extent set
            forth below, which records may be maintained on microfilm under the

            Company Act and shall be available for examination by
            representatives of the Securities and Exchange Commission.

            (1) A copy of this Code and any other Code which is, or any time
                within the past fives years has been, in effect shall be
                preserved in an easily accessible place.

            (2) A record of any violation of this Code and of any action taken

                accessible place for a period of not less than five years
                following the end of the fiscal year in which the violation
                occurs.

            (3) A copy of each report made by an officer or Trustee pursuant to
                this Code shall be preserved for a period of not less than five
                years from the end of the fiscal year in which it is made, the
                first two years in an easily accessible place.

            (4) A list of all persons who are, or within the past five years
                have been, required to make reports pursuant to this Code shall
                be maintained in an easily accessible place.

         C. Confidentiality.

            All reports of securities transactions and any other information

                                                               EXHIBIT NO. 16(b)


                   MASSACHUSETTS FINANCIAL SERVICES COMPANY
                             STATEMENT OF POLICY ON
                        PERSONAL SECURITIES TRANSACTIONS
                                (CODE OF ETHICS)

                        AS ADOPTED BY THE AUDIT COMMITTEE
                          EFFECTIVE AS OF MARCH 1, 2000

      As an investment advisory organization with substantial responsibilities
to clients, Massachusetts Financial Services Company ("MFS") has an obligation
to implement and maintain a meaningful policy governing the securities
transactions of its Directors, officers and employees ("MFS
representatives").(1) This policy is intended to minimize conflicts of interest,
and even the appearance of conflicts of interest, between members of the MFS
organization and its clients in the securities markets as well as to effect
compliance with the Investment Company Act, the Investment Advisers Act and the
Securities Exchange Act. This policy inevitably will restrict MFS
representatives in their securities transactions, but this is the necessary
consequence of undertaking to furnish investment advice to clients. In addition
to complying with the specific rules, we all must be sensitive to the need to
recognize any conflict, or the appearance of conflict, of interest whether or
not covered by the rules. When such situations occur, the interests of our
clients must supersede the interest of MFS representatives.

- --------
      (1) Employees of MFS Institutional Advisors, Inc., MFS Fund Distributors,
Inc., MFS Retirement Services, Inc., MFS International Ltd., MFS International
(U.K.) Ltd., MFS Service Center, Inc., Vertex Investment Management Inc. and MFS
Heritage Trust Company also are covered by this Code of Ethics.


      1. GENERAL FIDUCIARY PRINCIPLES. All personal investment activities
conducted by MFS representatives are subject to compliance with the following
principles: (i) the duty at all times to place the interests of MFS' clients
first; (ii) the requirement that all personal securities transactions be
conducted consistent with this Code of Ethics and in such a manner as to avoid
any actual or potential conflict of interest or any abuse of an individual's
position of trust and responsibility; and (iii) the fundamental standard that
MFS representatives should not take inappropriate advantage of their positions.

      2. APPLICABILITY OF RESTRICTIONS AND PROCEDURES. In recognition of the
different circumstances surrounding each MFS representative's employment,
various categories of MFS employees are subject to different restrictions under
this Code of Ethics. For purposes of applying this Code of Ethics, MFS employees
are divided into the general categories of Portfolio Managers, Investment
Personnel, Access Persons and Non-Access Persons, as each such term is defined
in Appendix A to this Code of Ethics, as amended from time to time by the Audit
Committee.

      As used in this Code of Ethics, the term "securities" includes not only
publicly traded equity securities, but also privately issued equity securities,
shares of closed-end funds, fixed income securities (including municipal bonds
and many types of U.S. Government securities), futures, options, warrants,
rights, swaps, commodities and other similar instruments. Moreover, the
restrictions of this Code of Ethics apply to transactions by Access Persons
involving securities and other instruments related to, but not necessarily the
same as, securities held or to be acquired on behalf of an MFS client.

      3. RESTRICTIONS ON PERSONAL SECURITIES TRANSACTIONS. No Access Person
shall trade in any security which is subject to a pending "buy" or "sell" order,
or has been considered for purchase of sale,(2) for a client of MFS until such
order is executed or withdrawn. In addition, no Investment Personnel shall trade
in any security after an MFS client trades in such security or such security has
been considered for purchase or sale on behalf of an MFS client until: (i) the
next business day following such trade or consideration (in the case of a
proposed trade by an Investment Personnel in the same direction as the MFS
client); or (ii) the eighth calendar day thereafter (in the case of a proposed
trade by an Investment Personnel in the opposite direction from the MFS client's
trade). No Portfolio Manager shall trade in any security within at least seven
calendar days before or after an MFS client whose account he or she manages
trades in such security or such security has been considered for purchase or
sale on behalf of such an MFS client. Any profits realized on trades within
these proscribed periods must be disgorged to the affected MFS client or, in the
event that the amount to be disgorged is relatively minor or difficult to
allocate, to charity. In addition, no MFS representative shall provide any
information about such transaction or recommendation to any person other than in
connection with the proper execution of such purchase or sale for an MFS
client's account.

- ----------
      (2) A security is deemed to have been "considered for purchase or sale"
when a recommendation to purchase or sell such security has been made and
communicated to a portfolio manager and, with respect to the person making the
recommendation, when such person seriously considers making such a
recommendation.

      Portfolio Managers should consider the problems inherent in purchasing for
their own account securities that are or may be suitable for a client's
portfolio. For example, a fortuitous early sale by the Manager for his or her
personal account may be criticized in hindsight if the same security later is
sold from the client's account at a lower price.

      GIFTS AND TRANSFERS. A gift or transfer shall be excluded from the
      preclearance requirements provided that the recipient represents in
      writing that he, she, they or it has no present intention of selling the
      donated security.

      SHORT SALES. No Access Person shall effect a short sale in any security
      held in a portfolio managed by MFS. Access Persons may engage in
      transactions in options and futures, subject to special preclearance rules
      applicable to certain of those transactions as described in Section 5
      below.

      INITIAL PUBLIC OFFERINGS. The purchase by Access Persons of securities
      (other than securities of registered open-end investment companies)
      offered at fixed public offering price by underwriters or a selling group
      is prohibited.(3) Rights (including rights purchased to acquire an
      additional full share) issued in respect of securities any Access Persons
      owns may be exercised, subject to preclearance; the decision whether or
      not to grant preclearance shall take into account, among other factors,
      whether the investment opportunity should be reserved for an MFS client
      and whether the investment opportunity is being or was offered to the
      individual by virtue of his or her position with MFS.

- ----------
      (3) The reason for this rule is that it precludes any possibility that
Access Persons might use MFS' clients' market stature as a means of obtaining
for themselves "hot" issues which otherwise might not be offered to them. In
addition, this rule eliminates the possibility that underwriters and selling
group members might seek by this means to gain favor with individuals in order
to obtain preferences from MFS.

      PRIVATE PLACEMENTS. Any acquisition by Access Persons of securities issued
      in a private placement is subject to preclearance. The decision whether or
      not to grant preclearance shall take into account, among other factors,
      whether the investment opportunity should be reserved for an MFS client
      and whether the investment opportunity is being offered to the individual
      by virtue of his or her position with MFS. Investment Personnel who have
      been precleared to acquire securities in a private placement are required
      to disclose that investment when they play a part in any subsequent
      consideration of an investment in the issuer for an MFS client. In such
      circumstances, the decision to purchase securities of the issuer for the
      MFS client shall be subject to an independent review by Investment
      Personnel with no personal interest in the issuer.

      NOTE: Acquisitions of securities in private placements by country clubs,
      yacht clubs and other similar entities need not be precleared, but are
      subject to the reporting, disclosure and independent review requirements.

      PROHIBITION ON SHORT-TERM TRADING PROFITS. All Investment Personnel are
      prohibited from profiting in the purchase and sale, or sale and purchase,
      of the same (or equivalent) securities within 60 calendar days. Any
      profits realized on such short-term trades must be disgorged to the
      affected MFS client (if any) or, in the event that the amount to be
      disgorged is relatively minor or difficult to allocate, to charity. This
      restriction on short-term trading profits shall not apply to transactions
      exempt from preclearance requirements, as described in Section 8 below.

      It is expected that all MFS representatives will follow these restrictions
in good faith and conduct their personal trading in keeping with the intended
purpose of this Code of Ethics. Note: Any Non-Access Person who receives any
information about any particular investment recommendation or executed or
proposed transaction for any MFS client is required to comply with all
preclearance and other requirements of this Code of Ethics applicable to Access
Persons. Any individual should feel free to take up with the Audit Committee any
case in which he or she feels inequitably burdened by these policies. The Audit
Committee may, in its sole discretion, grant appropriate exceptions from the
requirements of this Code of Ethics where warranted by applicable facts and
circumstances.

      4. BENEFICIAL OWNERSHIP. The requirements of this Code of Ethics apply to
any account in which an MFS representative has (i) "direct or indirect
beneficial ownership" or (ii) any "direct or indirect influence or control."
Under applicable SEC interpretations, such "beneficial ownership" includes
accounts of a spouse, minor children and dependent relatives resident in the MFS
representative's house, as well as any other contract, relationship,
understanding or other arrangement which results in an opportunity for the MFS
representative to profit or share profits from a transaction in securities.

      NOTE: The exception for accounts with respect to which an MFS
representative lacks "direct or indirect influence or control" is extremely
narrow, and should only be relied upon in cases which have been pre-approved in
writing by Stephen E. Cavan or Robert T. Burns of the Legal Department. Certain
"blind trust" arrangements approved by the Legal Department may be excluded from
the preclearance (but not the quarterly reporting) requirements of this Code of
Ethics.

      5. PRECLEARANCE REQUIREMENTS. In order to facilitate compliance with this
Code of Ethics, preclearance requests must be made and approved before any
transaction may be made by an Access Person. A preclearance request in the form
set forth in MFS' automated Code of Ethics system, as amended from time to time,
should be completed and submitted electronically for any order for an Access
Person's own account or one described in Section 4 above, or, in the case of an
Access Person who wishes to preclear while outside of the Boston area, should
either: (i) be completed in the form attached hereto, as amended from time to
time, signed and submitted by facsimile machine, to the Compliance Department;
or (ii) be submitted by telephone call to the Compliance Department. Any
preclearance request received before 3:00 p.m. on a business day will be
responded to as soon as available on the following business day. Preclearance
requests will be reviewed by Equity and Fixed Income Department personnel who
will be kept apprised of recommendations and orders to purchase and sell
securities on behalf of MFS clients, the completion or cancellation of such
orders and the securities currently held in portfolios managed by MFS. Their
advice will be forwarded to the Compliance Department.

      The preclearance process imposes significant burdens on the investment and
administrative departments within MFS. Accordingly, if the MFS Audit Committee
determines that an Access Person is making an excessive number of preclearance
requests, it reserves the right to limit such Access Person to a certain number
of preclearance requests per day or per period.

      An Access Person who obtains electronic or written notice from the
Compliance Department indicating consent to an order which the Access Person
proposes to enter for his or her own account or one described in Section 4 above
may execute that order only on the day when such notice is received unless
otherwise stated on the notice. Such notices will always be electronic or in
writing; however, in the case of an Access Person who wishes to preclear a
transaction while outside the Boston area, the Compliance Department will also
provide oral confirmation of the content of the written notice.

      Preclearance requests may be denied for any number of appropriate reasons,
most of which are confidential. For example, a preclearance request for a
security that is being considered for purchase or sale on behalf of an MFS
client may be denied for an extended period (e.g. 10 business days).
Accordingly, an Access Person is not entitled to receive any explanation or
reason if his or her preclearance request is denied, and any request for an
explanation by an Access Person may be deemed a violation of this Code of
Ethics.

      SIGNIFICANT OWNERSHIP BY MFS CLIENTS. In cases where MFS clients own, in
      the aggregate, 8% or more of the outstanding equity securities of an
      issuer, requests by Access Persons to purchase the securities of such
      issuer will be denied. Requests to preclear sales of such securities may
      be granted, subject to the standard requirements set forth in Section 3
      above.

      SECURITIES SUBJECT TO AUTOMATIC PURCHASES AND SALES FOR MFS CLIENTS.
      Certain MFS funds and institutional accounts are managed such that the
      securities held in such portfolios are regularly purchased or sold on an
      equal proportionate basis so as to preserve specified percentage
      weightings of such securities across such portfolios. Requests to preclear
      purchases of securities held in such portfolios will be denied. Requests
      to sell such securities may be granted, subject to the standard
      preclearance requirements set forth in Section 3 above.

      OPTIONS AND FUTURES TRANSACTIONS. Access Persons may purchase (to open)
      and sell (to close) call and put options and futures contracts on
      securities, subject to the preclearance and other requirements of this
      Code of Ethics; however, an Access Person may neither buy a put option on
      any security held in a portfolio managed by MFS nor write (sell to open)
      options and futures contracts. In the case of purchased put and call
      options, the preclearance of the exercise of such options as well as their
      purchase and sale, is required. Preclearance of the exercise of purchased
      put and call options shall be requested on the day before the proposed
      exercise or, if notice to the writer of such options is required before
      the proposed exercise date, the date before notice is proposed to be
      given, setting forth the proposed exercise date as well as the proposed
      notice date.(4) Purchases and sales of options or futures contracts to
      "close out" existing options or futures contracts must be precleared.(5)

- ----------
      (4) Access Persons should note that this requirement may result in their
not being allowed to exercise an option purchased by them on the exercise date
they desire, and in the case of a "European" option on the only date on which
exercise is permitted by the terms of the option.

      (5) Access Persons should note that as a result of this requirement, they
may not be able to obtain preclearance consent to close out an option or futures
contract before the settlement date. If such an option or futures contract is
automatically closed out, the gain, if any, on such transaction will be
disgorged in the manner described in Section 3 above.

      MFS CLOSED-END FUNDS. All transactions effected by any MFS representative
      in shares of any closed-end fund for which MFS or one of its affiliates
      acts as investment adviser shall be subject to preclearance and reporting
      in accordance with this Code of Ethics. Non-Access Persons are exempt from
      the preclearance and reporting requirements set forth in this Code of
      Ethics with respect to transactions in any other type of securities, so
      long as they have not received any information about any particular
      investment recommendation or executed or proposed transaction for any MFS
      client with respect to such security.

      6. DUPLICATE CONFIRMATION STATEMENT REQUIREMENT. In order to implement and
enforce the above policies, every Access Person shall arrange for his or her
broker to send MFS duplicate copies of all confirmation statements issued with
respect to the Access Person's transactions and all periodic statements for such
Access Person's securities accounts. The Compliance Department will coordinate
with brokerage firms in order to assist Access Persons in complying with this
requirement.

      7. REPORTING REQUIREMENT. Each Access Person shall report on or before the
tenth day of each calendar quarter any securities transactions during the prior
quarter in accounts covered by Section 4 above. Employees who fail to complete
and file such quarterly reports on a timely basis will be reported to the Audit
Committee and will be subject to sanctions. Reports shall be reviewed by the
Compliance Department.

In filing the reports for accounts within these rules, please note:

      (i)   You must file a report for every calendar quarter even if you had no
            reportable transactions in that quarter; all such reports shall be
            completed and submitted in the form set forth in MFS' automated Code
            of Ethics system.

      (ii)  Reports must show any sales, purchases or other acquisitions or
            dispositions, including gifts, exercises of conversion rights and
            exercises or sales of subscription rights. See Section 8 below for
            certain exceptions to this requirement.

      (iii) Reports will be treated confidentially unless a review of particular
            reports with the representative is required by the Audit Committee.

      (v)   Reports are made available for review by the Boards of Trustees of
            MFS investment company clients upon their request.

      NOTE: Any Access Person who maintains all of his or her personal
      securities accounts with one or more broker-dealer firms that send
      confirmation and periodic account statements in an electronic format
      approved by the Compliance Department, and who arranges for such firms to
      send such statements (no less frequently than quarterly) required by
      Section 6 above, shall not be required to prepare and file the quarterly
      reports required by this Section 7. However, each such Access Person shall
      be required to verify the accuracy and completeness of all such statements
      on at least an annual basis.

8.    CERTAIN EXCEPTIONS.

      MUTUAL FUNDS. Transactions in shares of any open-end investment companies,
including funds for which the MFS organization is investment adviser, need not
be precleared or reported.

      CLOSED-END FUNDS. Automatic reinvestments of distributions of closed-end
funds advised by MFS pursuant to dividend reinvestment plans of such funds need
only be reported. All other closed-end fund transactions must be precleared and
reported.

      MFS COMMON STOCK. Transactions in shares of stock of MFS need not be
precleared or reported.

      LARGE CAPITALIZATION STOCKS. Transactions in securities issued by
companies with market capitalizations of at least $5] billion generally will be
eligible for automatic preclearance (subject to certain exceptions), but must be
reported and are subject to post-trade monitoring. The Compliance Department
will maintain a list of issuers that meet this market capitalization
requirement. A preclearance request for a large capitalization company will be
denied whenever deemed appropriate.

      U.S. GOVERNMENT SECURITIES. Transactions in U.S. Treasury securities
(including options and futures contracts and other derivatives with respect to
such securities) need not be precleared or reported. Option and futures
contracts on U.S. Government obligations (other than U.S. Treasury securities)
and securities indices need not be precleared but must be reported. Transactions
in U.S. Government securities offered on the basis of "non-competitive tender"
need not be precleared or reported. However, U.S. Government obligations (other
than U.S. Treasury securities) offered by "subscription" must be precleared and
reported.

      OTHER EXCEPTIONS. Transactions in money market instruments and in options
on broad-based indices need not be precleared, although such transactions must
be reported. In addition, the following types of transactions need not be
precleared or reported: (i) stock dividends and stock splits; (ii) foreign
currency transactions; and (iii) transactions in real estate limited partnership
interests.

      9. DISCLOSURE OF PERSONAL SECURITIES HOLDINGS. All Access Persons are
required to disclose all personal securities holdings upon becoming an Access
Person (i.e. upon commencement of employment with MFS or transfer within MFS to
an Access Person position) and thereafter on an annual basis. Reports shall be
reviewed by the Compliance Department.

      10. GIFTS, ENTERTAINMENT AND FAVORS. MFS representatives must not make
business decisions that are influenced or appear to be influenced by giving or
accepting gifts, entertainment or favors. Investment Personnel are prohibited
from receiving any gift or other thing of more than de minimis value from any
person or entity that does business with or on behalf of MFS or its clients.
Invitations to an occasional meal, sporting event or other similar activity will
not be deemed to violate this restriction unless the occurrence of such events
is so frequent or lavish as to suggest an impropriety.

      11. SERVICE AS A DIRECTOR. All MFS representatives are prohibited from
serving on the boards of directors of commercial business enterprises, absent
prior authorization by the Management Committee based upon a determination that
the board service would be consistent with the interests of MFS' clients. In the
relatively small number of instances in which board service is authorized, MFS
representatives serving as directors may be isolated from other MFS
representatives through "Chinese Wall" or other appropriate procedures.

      12. CERTIFICATION OF COMPLIANCE WITH CODE OF ETHICS. All MFS
representatives (including Non-Access Persons) shall be required to certify
annually that (i) they have read and understand this Code of Ethics and
recognize that they are subject to its requirements applicable to them and (ii)
they have complied with all requirements of this Code of Ethics applicable to
them, and (in the case of Access Persons) have reported all personal securities
transactions (whether pursuant to quarterly reports from the Access Person or
duplicate confirmation statements and periodic reports from the Access Person's
broker-dealer) required to be reported pursuant to this Code of Ethics.

      13. BOARDS OF TRUSTEES OF MFS FUNDS. Any material amendment to this Code
of Ethics shall be subject to the approval by each of the Boards of Trustees
(including a majority of the disinterested Trustees on each such Board) of each
of the registered investment companies with respect to which MFS, or any
subsidiary of MFS, acts as investment adviser. In addition, on at least an
annual basis, MFS shall provide each such Board with a written report that: (i)
describes issues that arose during the preceding year under this Code of Ethics,
including without limitation information about any material violations of this
Code of Ethics and any sanctions imposed with respect to such violations; and
(ii) certifies to each such Board that MFS has adopted procedures reasonably
necessary to prevent Access Persons from violating this Code of Ethics.

      14. SANCTIONS. Any trading for an MFS representative's account which does
not evidence a good faith effort to comply with these rules will be subject to
Audit Committee review. If the Audit Committee determines that a violation of
this Code of Ethics or its intent has occurred, it may impose such sanctions as
it deems appropriate including forfeiture of any profit from a transaction
and/or termination of employment. Any violations resulting in sanctions will be
reported to the Boards of Trustees of MFS investment company clients and will be
reflected in the employee's personnel file.

                              CERTAIN DEFINED TERMS


      As used in this Code of Ethics, the following shall terms shall have the
meanings set forth below, subject to revision from time to time by the Audit
Committee:

      PORTFOLIO  MANAGERS  --  employees  who  are  authorized  to  make
      investment  decisions  for a  mutual  fund  or  client  portfolio.
      Note:  research analysts are deemed to be Portfolio  Managers with
      respect to the entire  portfolio of any fund managed  collectively
      by a committee of research analysts (e.g. MFS Research Fund).

      INVESTMENT PERSONNEL -- all Portfolio Managers as well as research
      analysts, traders and other members of the Equity Trading, Fixed Income
      and Equity Research Departments.

      ACCESS PERSONS -- all Portfolio Managers, Investment Personnel and other
      members of the following departments or groups: Institutional Advisors;
      Compliance; Fund Accounting; Investment Communications; and Technology
      Services & Solutions ("TS&S") (excluding, however, TS&S employees who are
      employed at Lafayette Corporate Center and certain TS&S employees who may
      be specifically excluded by the Compliance or Legal Departments); also
      included are members of the MFS Management Committee, the MFS
      Administrative Committee and the MFS Operations Committee. In certain
      instances, non-employee consultants and other independent contractors may
      be deemed Access Persons and therefore be subject to some or all of the
      requirements set forth in this Code of Ethics.

      NON-ACCESS PERSONS -- all employees of the following departments or
      groups: Corporate Communications; Corporate Finance; Facilities
      Management; Human Resources; Internal Audit (unless undergoing an audit of
      an access area); Legal; MFS Service Center, Inc. (other than TS&S
      employees who are employed at 500 Boylston Street); Retired Partners;
      Travel and Conference Services; the International Division; MFS
      International Ltd.; MFS Fund Distributors, Inc.; and MFS Retirement
      Services, Inc. Note: Any Non-Access Person who receives any information
      about any particular investment recommendation or executed or proposed
      transaction for any MFS client is required to comply with all preclearance
      and other requirements of this Code of Ethics applicable to Access
      Persons. Any Non-Access Person who regularly receives such information
      will be reclassified as an Access Person. In addition, transactions in
      shares of the MFS closed-end funds are subject to all such preclearance
      and reporting requirements by all MFS representatives (see Section 5 of
      this Code of Ethics).

certain specific categories of securities that are exempted under the MFS Code
of Ethics. If necessary, continue on the reverse side. Please note that special
rules apply to the preclearance of option and futures transactions. If the
transaction is to be other than a straightforward sale or purchase of
securities, mark it with an asterisk and explain the nature of the transaction
on the reverse side. Describe the nature of each account in which the
transaction is to take place, i.e., personal, spouse, children, charitable
trust, etc.
