          SUPPLEMENT DATED SEPTEMBER 1, 1999 TO THE CURRENT PROSPECTUS

This Supplement describes the fund's class I shares, and it supplements certain
information in the fund's Prospectus dated September 1, 1999. 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.       RISK RETURN SUMMARY

         Performance Table.  The "Performance Table" is intended to indicate
some of the risks of investing in the fund by showing changes in the fund's
performance over time. The table is supplemented as follows:

              AVERAGE ANNUAL TOTAL RETURNS AS OF DECEMBER 31, 1998

                                                  1 YEAR     5 YEARS    10 YEARS
                                                  ------     -------    --------
Class I shares                                      4.83%     6.98%      9.32%
Lehman Brothers Government/Corporate Bond Index+*   9.49%     7.31%      9.34%
Average corporate debt BBB-rated fund+              6.23%     6.98%      9.16%
- -----------------------------

*  Lehman Brothers Government/Corporate Bond Index is a broad based unmanaged,
   market-value-weighted index of all debt obligations of the U.S. Treasury and
   U.S. government agencies (excluding mortgage-backed securities) and of all
   publicly issued fixed-rate, nonconvertible, investment-grade domestic
   corporate debt.

The fund commenced investment operations on May 8, 1974 with the offering of
class A shares, and subsequently offered class I shares on January 2, 1997.
Class I share performance includes the performance of the fund's class A shares
for periods prior to the offering of class I shares. This blended class I share
performance has been adjusted to take into account the fact that class I shares
have no initial sales charge (load). This blended performance has not been
adjusted to take into account differences in class specific operating expenses.
Because operating expenses of class I shares are lower than those of class A
shares, this blended class I share performance is lower than the performance of
class I shares would have been had class I shares been offered for the entire
period.

2.       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:

         ANNUAL FUND OPERATING EXPENSES (EXPENSES THAT ARE DEDUCTED FROM FUND
ASSETS):

Management Fees................................................       0.38%
Distribution and Service (12b-1) Fees..........................       0.00%
Other Expenses(1)..............................................       0.27%
Total Annual Fund Operating Expenses...........................       0.65%
- --------------------------
(1)  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. "Other Expenses" do not
     take into account these expense reductions, and therefore do not represent
     the actual expenses of the fund.

3.       EXAMPLE OF EXPENSES

         The "Example of Expenses" table is intended to help you compare the
         cost of investing in the fund with the cost of investing in other
         mutual funds.

         These 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.

         The table is supplemented as follows:

          SHARE CLASS         YEAR 1    YEAR 3    YEAR 5    YEAR 10
          -----------         ------    ------    ------    -------

           Class I shares       $66      $208       $362      $810

4.       DESCRIPTIONS 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 the 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;

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

         o any retirement plan, endowment or foundation which:

           >  purchases shares directly through MFD (rather than through a third
              party broker or dealer or other financial adviser),

           >  has, at the time of purchase of class I shares, aggregate assets
              of at least $100 million, and

           >  invests at least $10 million in class I shares of the fund either
              alone or in combination with investments in class I shares of
              other MFS Funds (additional investments may be made in any
              amount).

MFD may accept purchases from smaller plans, endowments or foundations or in
smaller amounts if it believes, in its sole discretion, that such entity's
aggregate assets will equal or exceed $100 million, or that such entity will
make additional investments which will cause its total investment to equal or
exceed $10 million, within a reasonable period of time;

         o bank trust departments or law firms acting as trustee or manager for
           trust accounts which initially invest, on behalf of their clients, at
           least $100,000 in class I shares of the fund (additional investments
           may be made in any amount). MFD may accept smaller initial purchases
           if it believes, in its sole discretion, that the bank trust
           department or law firm will make additional investments, on behalf of
           its trust clients, which will cause its total investment to equal or
           exceed $100,000 within a reasonable period of time; and

         o certain retirement plans offered, administered or sponsored by
           insurance companies, provided that these plans and insurance
           companies meet certain criteria established by MFD from time to time.

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 fund's policies, disqualify the purchaser as an eligible investor in
class I shares.

5.       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.

6.       FINANCIAL HIGHLIGHTS

The "Financial Highlights" table is intended to help you understand the fund's
financial performance. It is supplemented as follows:

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

o   INVESTMENT OBJECTIVE

    The fund's main investment objective is to provide as high a level of
    current income as is believed to be consistent with prudent risk. Its
    secondary objective is to protect shareholders' capital. The fund's
    objectives 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 the following fixed income securities:


    o  corporate bonds, which are bonds or other debt obligations issued by
       domestic or foreign (including emerging market) corporations or other
       similar entities.

    o  U.S. government securities, which are bonds or other debt obligations
       issued by, or whose principal and interest payments are guaranteed or
       supported by, the U.S. government or one of its agencies or
       instrumentalities (including mortgage-backed securities), and

    o  mortgage-backed and asset-backed securities, which represent interests in
       a pool of assets such as mortgage loans, car loan receivables or credit
       card receivables.

      While the fund may purchase corporate bonds which have been assigned lower
    credit ratings by credit rating agencies (commonly known as junk bonds), it
    focuses on investment grade bonds. These bonds are rated in the higher
    rating categories by credit rating agencies or are unrated and considered by
    MFS to be comparable in quality.

      In selecting fixed income investments for the fund, MFS considers the
    views of its large group of fixed income portfolio managers and research
    analysts. This group periodically assesses the three-month total return
    outlook for various segments of the fixed income markets. This three-month
    "horizon" outlook is used by the portfolio manager(s) of MFS' fixed income
    oriented funds (including the fund) as a tool in making or adjusting a
    fund's asset allocations to various segments of the fixed income markets. In
    assessing the credit quality of fixed income securities, MFS does not rely
    solely on the credit ratings assigned by credit rating agencies, but rather
    performs its own independent credit analysis.

      The fund may invest in derivative securities. Derivatives are securities
    whose value may be based on other securities, currencies, interest rates,
    or indices. Derivatives include:

    o  futures and forward contracts,

    o  options on futures contracts, foreign currencies, securities and bond
       indices,

    o  structured notes and indexed securities, and

    o  swaps, caps, collars and floors.

    PRINCIPAL RISKS OF AN INVESTMENT


    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  Allocation Risk: The fund will allocate its investments among various
       segments of the fixed income markets based upon judgments made by MFS.
       The fund could miss attractive investment opportunities by underweighting
       markets where there are significant returns, or could lose value
       overweighting markets where there are significant declines.

    o  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.

    o  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.

    o  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.

    o  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  Junk Bond Risk:

       >  Higher Credit Risk: Junk bonds are subject to a substantially higher
          degree of credit risk than investment grade 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  Mortgage-Backed and Asset-Backed Securities Risk


       >  Maturity Risk:

          + Mortgage-Backed Securities: A mortgage-backed security will mature
            when all the mortgages in the pool mature or are prepaid.
            Therefore, mortgage-backed securities do not have a fixed
            maturity, and their expected maturities may vary when interest
            rates rise or fall.


            - When interest rates fall, homeowners are more likely to prepay
              their mortgage loans. An increased rate of prepayments on the
              fund's mortgage-backed securities will result in an unforeseen
              loss of interest income to the fund as the fund may be required to
              reinvest assets at a lower interest rate. Because prepayments
              increase when interest rates fall, the prices of mortgage-backed
              securities do not increase as much as other fixed income
              securities when interest rates fall.


            - When interest rates rise, homeowners are less likely to prepay
              their mortgage loans. A decreased rate of prepayments lengthens
              the expected maturity of a mortgage-backed security. Therefore,
              the prices of mortgage-backed securities may decrease more than
              prices of other fixed income securities when interest rates rise.

          + Collateralized Mortgage Obligations: The fund may invest in
            mortgage-backed securities called collateralized mortgage
            obligations (CMOs). CMOs are issued in separate classes with
            different stated maturities. As the mortgage pool experiences
            prepayments, the pool pays off investors in classes with shorter
            maturies first. By investing in CMOs, the fund may manage the
            prepayment risk of mortgage-backed securities. However,
            prepayments may cause the actual maturity of a CMO to be
            substantially shorter than its stated maturity.

          + Asset-Backed Securities: Asset-backed securities have prepayment
            risks similar to mortgage-backed securities.

       >  Credit Risk: As with any fixed income security, mortgage-backed and
          asset-backed securities are subject to the risk that the issuer will
          default on principal and interest payments. It may be difficult to
          enforce rights against the assets underlying mortgage-backed and
          asset-backed securities in the case of default. The U.S. government or
          its agencies may guarantee the payment of principal and interest on
          some mortgage-backed securities. Mortgage- backed securities and
          asset-backed securities issued by private lending institutions or
          other financial intermediaries may be supported by insurance or other
          forms of guarantees.

       >  Derivatives Risk:

          + Hedging Risk: When a derivative is used as a hedge against an
            opposite position that the fund also holds, any loss generated by
            the derivative should be substantially offset by gains on the
            hedged investment, and vice versa. While hedging can reduce or
            eliminate losses, it can also reduce or eliminate gains.


          + Correlation Risk: When the fund uses derivatives to hedge, it
            takes the risk that changes in the value of the derivative will
            not match those of the asset being hedged. Incomplete correlation
            can result in unanticipated losses.


          + Investment Risk: When the fund uses derivatives as an investment
            vehicle to gain market exposure, rather than for hedging purposes,
            any loss on the derivative investment will not be offset by gains
            on another hedged investment. The fund is therefore directly
            exposed to the risks of that derivative. Gains or losses from
            derivative investments may be substantially greater than the
            derivative's original cost.

          + Availability Risk: Derivatives may not be available to the fund
            upon acceptable terms. As a result, the fund may be unable to use
            derivatives for hedging or other purposes.

          + Credit Risk: When the fund uses derivatives, it is subject to the
            risk that the other party to the agreement will not be able to
            perform.

    o  Active or Frequent Trading Risk: The fund has engaged and may engage in
       active and frequent trading to achieve its 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.

    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 below are intended to indicate some of
    the risks of investing in the fund by showing changes in the fund's
    performance over time. The performance table also shows how the fund's
    performance over time compares with that of one or more broad measures of
    market performance. The chart and table provide past performance
    information. The fund's past performance does not necessarily indicate how
    the fund will perform in the future. The performance information in the
    chart and table is based upon calendar year periods, while the performance
    information presented under the caption "Financial Highlights" and in the
    fund's shareholder reports is based upon the fund's fiscal year.
    Therefore, these performance results differ.

    BAR CHART

    The bar chart shows changes in the annual total returns of the fund's
    class A shares for the past ten calendar years. The chart and related
    notes do not take into account any sales charges (loads) that you may be
    required to pay upon purchase or redemption of the fund's shares, but do
    include the reinvestment of distributions. Any sales charge will reduce
    your return. The return of the fund's other classes of shares will differ
    from the class A returns shown in the bar chart, depending upon the
    expenses of those classes.

                    1989      13.52%
                    1990       7.25%
                    1991      18.04%
                    1992       6.29%
                    1993      13.86%
                    1994      (4.46)%
                    1995      21.47%
                    1996       3.94%
                    1997      10.35%
                    1998       4.47%


      The total return for the fund's class A shares for the three month
    period ended March 31, 1999 was (0.04)%. During the period shown in the
    bar chart, the highest quarterly return was 7.74% (for the calendar
    quarter ended June 30, 1995) and the lowest quarterly return was (3.58)%
    (for the calendar quarter ended March 31, 1994).


    PERFORMANCE TABLE

    This table shows how the average annual total returns of each class of the
    fund compare to a broad measure of market performance and various other
    market indicators and assumes the reinvestment of distributions.

    AVERAGE ANNUAL TOTAL RETURNS AS OF DECEMBER 31, 1998
    ............................................................................
                                                 1 Year      5 Year     10 Year

    Class A shares                               (0.49)%       5.78%       8.70%
    Class B shares                               (0.14)%       5.72%       8.80%
    Class C shares                                 2.81%       6.05%       8.84%
    Lehman Brothers Gov/Corp. Bond Index*+         9.49%       7.31%       9.34%
    Average corp. debt BBB-rated fund+             6.23%       6.98%       9.16%

    ------
    +Source: Lipper Analytical Services, Inc.
    *The Lehman Brothers Gov/Corp. Bond Index is a broad based unmanaged,
     market-value-weighted index of all debt obligations of the U.S.
     Treasury and U.S. government agencies (excluding mortgage-backed
     securities) and of all publicly issued fixed-rate, nonconvertible,
     investment-grade domestic corporate debt.

    Class A share performance takes into account the deduction of the 4.75%
    maximum sales charge. Class B share performance takes into account the
    deduction of the applicable contingent deferred sales charge (referred to
    as a CDSC), which declines over six years from 4% to 0%. Class C share
    performance takes into account the deduction of the 1% CDSC.

      The fund commenced investment operations on May 8, 1974 with the
    offering of class A shares and subsequently offered class B shares on
    September 7, 1993, and class C shares on January 3, 1994. Class B and
    class C share performance include the performance of the fund's class A
    shares for periods prior to the offering of class B and class C shares.
    This blended class B and class C share performance has been adjusted to
    take into account the CDSC applicable to class B and class C shares,
    rather than the initial sales charge (load) applicable to class A shares.
    This blended performance has not been adjusted to take into account
    differences in class specific operating expenses. Because operating
    expenses of class B and C shares are higher than those of class A shares,
    this blended class B and C share performance is higher than the
    performance of class B and C shares would have been had class B and C
    shares been offered for the entire period. If you would like the fund's
    current yield, contact the MFS Service Center at the toll free number set
    forth on the back cover page.

II  EXPENSE SUMMARY
- ----------------------

o   EXPENSE TABLE

    This table describes the fees and expenses that you may pay when you buy,
    redeem and hold shares of the fund.

    Distribution and Service (12b-1) Fees(2) ....    0.30%      1.00%     1.00%


    Other Expenses(3) ...........................    0.27%      0.27%     0.27%
                                                     -----      -----     -----
    Total Annual Fund Operating Expenses ........    0.95%      1.65%     1.65%


    ------
    (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) 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.
        "Other Expenses" do not take into account these expense reductions,
        and are therefore higher than the actual expenses of the fund.

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.

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

SHARE CLASS                            YEAR 1     YEAR 3    YEAR 5   YEAR 10
- ------------------------------------------------------------------------------

Class A shares                          $567       $763     $  976    $1,586

Class B shares
  Assuming redemption at end of period  $568       $820     $1,097    $1,768
  Assuming no redemption                $168       $520     $  897    $1,768

Class C shares
  Assuming redemption at end of period  $268       $520     $  897    $1,955
  Assuming no redemption                $168       $520     $  897    $1,955

III  CERTAIN INVESTMENT STRATEGIES AND RISKS

o   FURTHER INFORMATION ON INVESTMENT STRATEGIES AND RISKS

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

IV  MANAGEMENT OF THE FUND
- ----------------------------

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 $113.4 billion on behalf of
    approximately 4.6 million investor accounts as of July 31, 1999. As of
    such date, the MFS organization managed approximately $21.6 billion of
    assets in fixed income funds and fixed income portfolios of MFS
    Institutional Advisors, Inc. MFS is located at 500 Boylston Street,
    Boston, Massachusetts 02116.


      MFS provides investment management and related administrative services
    and facilities to the fund, including portfolio management and trade
    execution. For these services, the fund pays MFS an annual management fee
    computed and paid monthly, based upon a percentage of the average daily
    net assets of the fund plus a percentage of its gross income (i.e., income
    other than gains from the sale of securities or gains received from
    futures contracts) in each case on an annualized basis for the then-
    current fiscal year of the fund. The applicable percentages are:


       ANNUAL RATE OF MANAGEMENT FEE           ANNUAL RATE OF MANAGEMENT FEE
     BASED ON AVERAGE DAILY NET ASSETS             BASED ON GROSS INCOME
     ---------------------------------         ------------------------------
    0.225% of the first $200 million         2.75% of the first $20 million
    0.191% in excess of $200 million         2.34% in excess of $20 million

    For the fund's fiscal year ended April 30, 1999, MFS received management
    fees under the Advisory Agreement equivalent to 0.38% of the fund's
    average daily net assets.


o   PORTFOLIO MANAGER

    The fund's portfolio manager is Geoffrey L. Kurinsky, a Senior Vice
    President of MFS. Mr. Kurinsky has been the portfolio manager of the fund
    since 1989 and has been employed as a portfolio manager by MFS since 1987.

o   ADMINISTRATOR

    MFS provides the fund with certain financial, legal, compliance,
    shareholder communications and other administrative services. MFS is
    reimbursed by the fund for a portion of the costs it incurs in providing
    these services.


o   DISTRIBUTOR


    MFS Fund Distributors, Inc. (referred to as MFD), a wholly owned
    subsidiary of MFS, is the distributor of shares of the fund.

o   SHAREHOLDER SERVICING AGENT

    MFS Service Center, Inc. (referred to as MFSC), a wholly owned subsidiary
    of MFS, performs transfer agency and certain other services for the fund,
    for which it receives compensation from the fund.

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

    The fund offers class A, B and C shares through this prospectus. The 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.

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 $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 Fundamental 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 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

       >  the plan has not redeemed its class B shares in the MFS funds in order
          to purchase class A shares under this category.

    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, a market value of $500,000 or
          more invested in shares of any class or classes of the MFS Funds.

          THE RETIREMENT PLAN WILL QUALIFY UNDER THIS CATEGORY ONLY IF THE PLAN
          OR ITS SPONSORING ORGANIZATION INFORMS MFSC PRIOR TO THE PURCHASES
          THAT THE PLAN HAS 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 A PLAN QUALIFIES
          UNDER THIS CATEGORY; 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, 1997;

       >  the plan's 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. Three 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.

    o  Purchases of class B shares prior to January 1, 1993 made on any day
       during a calendar year will age one year at the close of business on
       December 31 of that 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

    The 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. Assets
    attributable to class A shares sold prior to March 1, 1991 are subject to
    a reduced service fee. A portion of the class A distribution fee equal to
    0.05% is currently not being imposed and will be paid by the fund when the
    trustees of the fund approve the fee. Over time, these fees will increase
    the cost of your shares and may cost you more than paying other types of
    sales charges.

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

    You may purchase, exchange and redeem class A, B and C shares of the 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 Fundamental 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, the 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. This privilege applies to shares of the MFS
    money market funds only under certain circumstances.

    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 the fund makes an in-kind
    distribution, you could incur the brokerage and transaction charges when
    converting the securities to cash. The fund does not expect to make in-
    kind distributions, and if it does, the fund 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 the 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 the 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  Dividends and capital gain distributions reinvested in additional shares
       (this option will be assigned if no other option is specified);

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

    o  Dividends 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. Dividends and
    capital gain distributions in amounts less than $10 will automatically be
    reinvested in additional shares of the fund. If you have elected to
    receive dividends and/or capital gain 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 dividends and other distributions
    reinvested in additional shares. Your request to change a distribution
    option must be received by MFSC by the record date for a dividend or
    distribution in order to be effective for that dividend or 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 $100,000 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.


    FREE CHECKWRITING. You may redeem your class A or class C shares by writing
    checks against your account. Checks must be for at least $500 and
    investments made by check must have been in your account for at least 15
    days before you can write checks against them. There is no charge for this
    service. To authorize your account for checkwriting, contact MFSC (see back
    cover page for address and phone number).


      Shares in your account equal in value to the amount of the check plus
    the applicable CDSC (if any) and any income tax required to be withheld
    (if any) are redeemed to cover the amount of the check. If your account
    value is not great enough to cover these amounts, your check will be
    dishonored.

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

o   PRICING OF FUND SHARES


    The price of each class of the 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). To determine net asset value, the 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
    the 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 the 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.

    The 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 the fund's shares may change
    on days when you will not be able to purchase or redeem the fund's shares.

o   DISTRIBUTIONS

    The fund intends to pay substantially all of its net income (excluding any
    realized net capital gains) to shareholders as dividends at least monthly.
    Any realized net capital gains are distributed 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 the fund may have
    on your particular tax situation.

    TAXABILITY OF DISTRIBUTIONS. As long as the fund qualifies for treatment
    as a regulated investment company (which it has in the past and intends to
    do in the future), 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 the 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.

    Fund distributions will reduce the 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.

    If you are neither a citizen nor a resident of the U.S., the 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 the fund. The 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 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. Prospective investors should read the
    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 FUND

    MFS may serve as the investment adviser to other funds which have similar
    investment goals and principal investment policies and risks to the fund,
    and which may be managed by the fund's portfolio manager(s). While the
    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   YEAR 2000 READINESS DISCLOSURE

    The fund could be adversely affected if the computer systems used by MFS,
    the fund's other service providers or the companies in which the fund
    invests do not properly process date-related information from and after
    January 1, 2000. MFS recognizes the importance of the Year 2000 issue and,
    to address Year 2000 compliance, created a separately funded Year 2000
    Program Management Office in 1996 comprised of a specialized staff
    reporting directly to MFS senior management. The Office, with the help of
    external consultants, is responsible for overall coordination, strategy
    formulation, communications and issue resolution with respect to Year 2000
    issues. While MFS systems will be tested for Year 2000 readiness before
    the turn of the century, there are significant systems interdependencies
    in the domestic and foreign markets for securities, the business
    environments in which companies held by the fund operate and in MFS' own
    business environment. MFS has been working with the fund's other service
    providers to identify and respond to potential problems with respect to
    Year 2000 readiness and to develop contingency plans. Year 2000 readiness
    is also one of the factors considered by MFS in its ongoing assessment of
    companies in which the fund invests. There can be no assurance, however,
    that these steps will be sufficient to avoid any adverse impact on the
    fund.

o   PROVISION OF ANNUAL AND SEMIANNUAL REPORTS

    To avoid sending duplicate copies of materials to households, only one
    copy of the fund's annual and semiannual report 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 be sent personally
    to that shareholder.

IX  FINANCIAL HIGHLIGHTS
- -------------------------

    The financial highlights table is intended to help you understand the
    fund's financial performance for the past 5 years. Certain information
    reflects financial results for a single fund share. The total returns in
    the table represent the rate by which an investor would have earned (or
    lost) on an investment in the fund (assuming reinvestment of all
    distributions). This information has been audited by the fund's
    independent auditors, whose report, together with the fund's financial
    statements, are included in the fund's Annual Report to shareholders. The
    fund's Annual Report is available upon request by contacting MFSC (see
    back cover for address and telephone number). These financial statements
    are incorporated by reference into the SAI. The fund's independent
    auditors are Deloitte & Touche LLP.

+++For the year ended April 30, 1998, the per share distribution in excess of net investment income was less
   than $0.01.
  #Per share data are based on average shares outstanding.
 ##The fund had 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's expenses are
   calculated without reduction for this expense offset arrangement.
(+)Total returns for class A shares do not include the applicable sales charge. If the charge had been included,
   the results would have been lower.

(S)The investment adviser and/or the distributor voluntarily waived a portion of their fees for certain of the
   periods indicated. If the fee had been incurred by the fund, the net investment income per share and the
   ratios would have been:

      INVESTMENT TECHNIQUES, PRACTICES AND RISKS
      The investment objective and principal investment policies of the Fund are
      described in the Prospectus. In pursuing its investment objective and
      principal investment policies, the Fund may engage in a number of
      investment techniques and practices, which involve certain risks. These
      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 apply to these investment techniques and practices.

      o  Non-Dollar Denominated Non-Canadian Foreign Securities Exposure may not
         exceed 10% of the Fund's net assets

      o  Lower Rated Bonds may not exceed 20% of the Fund's net assets.

      o  Lending of Portfolio Securities may not exceed 30% of the Fund's net
         assets.

      INVESTMENT RESTRICTIONS
      The Fund has adopted the following restrictions which cannot be changed
      without the approval of the holders of a majority of the 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).

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

      The Fund may not:

      (1)  borrow money in an amount in excess of 10% of its gross assets, and
           then only as a temporary measure for extraordinary or emergency
           purposes, or pledge, mortgage or hypothecate an amount of its
           assets (taken at market value) in excess of 15% of its gross
           assets, in each case taken at the lower of cost or market value and
           subject to a 300% asset coverage requirement (for the purpose of
           this restriction, collateral arrangements with respect to options,
           Futures Contracts, Options on Futures Contracts, Forward Contracts
           and options on foreign currencies and payments of initial and
           variation margin in connection therewith are not considered a
           pledge of assets);

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

      (3)  concentrate its investments in any particular industry, but if it
           is deemed appropriate for the achievement of its investment
           objectives, the Fund may invest up to 25% of its assets (taken at
           market value at the time of each investment) in securities of
           issuers in any one industry;

      (4)  purchase or sell real estate (including limited partnership
           interests but excluding securities of companies, such as real
           estate investment trusts, which deal in real estate or interests
           therein), or mineral leases, commodities or commodity contracts
           (except options, Futures Contracts, Options on Futures Contracts,
           Forward Contracts and options on foreign currencies) in the
           ordinary course of its business. The Fund reserves the freedom of
           action to hold and to sell real estate or mineral leases,
           commodities or commodity contracts (including options, Futures
           Contracts, Options on Futures Contracts, Forward Contracts and
           options on foreign currencies) acquired as a result of the
           ownership of securities. The Fund will not purchase securities for
           the purpose of acquiring real estate or mineral leases, commodities
           or commodity contracts (except options, Futures Contracts, Options
           on Futures Contracts, Forward Contracts and options on foreign
           currencies);

      (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 in accordance with its investment
           objectives and policies, the lending of portfolio securities, or
           the investment of the Fund's assets in repurchase agreements, shall
           not be considered the making of a loan;

      (6)  purchase the securities of any issuer if such purchase, at the time
           thereof, would cause more than 5% of its total assets (taken at
           market value) to be invested in the securities of such issuer,
           other than cash items and U.S. Government securities;

      (7)  purchase voting securities of any issuer if such purchase, at the
           time thereof, would cause more than 10% of the outstanding voting
           securities of such issuer to be held by the Fund; or purchase
           securities of any issuer if such purchase at the time thereof would
           cause more than 10% of any class of securities of such issuer to be
           held by the Fund. For this purpose all indebtedness of an issuer
           shall be deemed a single class and all preferred stock of an issuer
           shall be deemed a single class;

      (8)  invest for the purpose of exercising control or management;

      (9)  purchase securities issued by any other registered investment
           company except by purchase in the open market where no commission
           or profit to a sponsor or dealer results from such purchase other
           than the customary broker's commission, or except when such
           purchase, though not made in the open market, is part of a plan of
           merger or consolidation; provided, however, that the Fund shall not
           purchase such securities if such purchase at the time thereof would
           cause more than 10% of its total assets (taken at market value) to
           be invested in the securities of such issuers; and, provided
           further, that the Fund shall not purchase securities issued by any
           open-end investment company;

      (10) invest more than 5% of its assets in companies which, including
           predecessors, have a record of less than three years' continuous
           operation;

      (11) Purchase or retain in its portfolio any securities issued by an
           issuer any of whose officers, directors, trustees or security
           holders is an officer or Trustee of the Trust, or is an officer or
           Director of the Adviser, if after the purchase of the securities of
           such issuer by the Fund one or more of such persons owns
           beneficially more than  1/2 of 1% of the shares or securities, or
           both, of such issuer, and such persons owning more than  1/2 of 1%
           of such shares or securities together own beneficially more than 5%
           of such shares or securities, or both;

      (12) purchase any securities or evidences of interest therein on margin,
           except to make deposits on margin in connection with options,
           Futures Contracts, Options on Futures Contracts, Forward Contracts
           and options on foreign currencies, and except that the Fund may
           obtain such short-term credit as may be necessary for the clearance
           of purchases and sales of securities;

      (13) sell any security which the Fund does not own unless by virtue of
           its ownership of other securities the Fund has at the time of sale
           a right to obtain securities without payment of further
           consideration equivalent in kind and amount to the securities sold
           and provided that if such right is conditional the sale is made
           upon the same conditions;

      (14) purchase or sell any put or call option or any combination thereof,
           provided, that this shall not prevent the purchase, ownership,
           holding or sale of warrants where the grantor of the warrants is
           the issuer of the underlying securities or the writing, purchasing
           and selling of puts, calls or combinations thereof with respect to
           securities, Futures Contracts and foreign currencies; or

      (15) invest in securities which are restricted as to disposition under
           federal securities laws unless the Board of Trustees has determined
           that such securities are liquid based upon trading markets for the
           specific security, if more than 10% of the Fund's assets (taken at
           market value) would be invested in such securities.


        In addition, the Fund has the following non-fundamental policy which may
      be changed without shareholder approval.


      (1)  The Fund will not invest 25% or more of the market value of its
           total assets in securities of issuers in any one industry.

        Except for fundamental investment restrictions No. 1 and 15, these
      investment restrictions 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 policy.

    +Annualized, based upon the last distribution.

    The Fund commenced investment operations on May 8, 1974 with the offering
    of class A shares and subsequently offered class B shares on September 7,
    1993, class C shares on January 3, 1994, and class I shares on January 2,
    1997. Class B and class C share performance include the performance of the
    Fund's class A shares for periods prior to the offering of class B and
    class C shares. This blended class B and class C share performance has
    been adjusted to take into account the CDSC applicable to class B and
    class C shares, rather than the initial sales charge (load) applicable to
    class A shares. This blended performance has not been adjusted to take
    into account differences in class specific operating expenses. Because
    operating expenses of class B and C shares are higher than those of class
    A shares, this blended class B and C share performance is higher than the
    performance of class B and C shares would have been had class B and C
    shares been offered for the entire period. If you would like the Fund's
    current yield, contact the MFS Service Center at the toll free number set
    forth on the back cover page of Part II of this SAI.

    Class I share performance includes the performance of the Fund's class A
    shares for periods prior to the offering of class I shares. Class I share
    performance generally would have been higher than class A share
    performance had class I shares been offered for the entire period, because
    operating expenses (e.g., distribution and service fees) attributable to
    class I shares are lower than those of class A shares. Class I share
    performance has been adjusted to take into account the fact that class I
    shares have no initial sales charge.

    Performance results include any applicable expense subsidies and waivers,
    which may cause the results to be more favorable.

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; 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; 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.

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 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.

  PART II - APPENDIX A
- ------------------------

      WAIVERS OF SALES CHARGES
      This Appendix sets forth the various circumstances in which all applicable
      sales charges are waived (Section I), the initial sales charge and the
      CDSC for Class A shares are waived (Section II), and the CDSC for Class B
      and Class C shares is waived (Section III). Some of the following
      information will not apply to certain funds in the MFS Family of Funds,
      depending on which classes of shares are offered by such fund. 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.

I     WAIVERS OF ALL APPLICABLE SALES CHARGES
      In the following circumstances, the initial sales charge imposed on
      purchases of Class A shares and the CDSC imposed on certain redemptions of
      Class A shares and on redemptions of Class B and Class C shares, as
      applicable, are waived:

      DIVIDEND REINVESTMENT
        o Shares acquired through dividend or capital gain reinvestment; and

        o Shares acquired by automatic reinvestment of distributions of
          dividends and capital gains of any fund in the MFS Funds pursuant to
          the Distribution Investment Program.

     CERTAIN ACQUISITIONS/LIQUIDATIONS

  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

      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).

    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.

  PART II - APPENDIX C
- ------------------------


    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. 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. 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.

    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.

    ABSENCE OF RATING: Where no rating has been assigned or where a rating has
    been suspended or withdrawn, it may be for reasons unrelated to the
    quality of the issue. Should no rating be assigned, the reason may be one
    of the following:

        1.  An application for rating was not received or accepted.

        2.  The issue or issuer belongs to a group of securities or companies
            that are not rated as a matter of policy.

        3.  There is a lack of essential data pertaining to the issue or
            issuer.

        4.  The issue was privately placed, in which case the rating is not
            published in Moody's publications.

    Suspension or withdrawal may occur if new and material circumstances
    arise, the effects of which preclude satisfactory analysis; if there is no
    longer available reasonable up-to-date data to permit a judgment to be
    formed; if a bond is called for redemption; or for other reasons.

                        STANDARD & POOR'S RATINGS SERVICES

    AAA: An obligation rated AAA has the highest rating assigned by S&P. 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: 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.

    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. Securities are not meeting current obligations and
    are extremely speculative. DDD designates the highest potential for
    recovery of amounts outstanding on any securities involved. For U.S.
    corporates, for example, DD indicates expected recovery of 50% -- 90% of
    such outstandings, 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.

          Supplement dated September 1, 1999 to the Current Prospectus

This Supplement describes the fund's class I shares, and it supplements certain
information in the fund's Prospectus dated September 1, 1999. 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.       RISK RETURN SUMMARY

         Performance Table.  The "Performance Table" is intended to indicate
some of the risks of investing in the fund by showing changes in the fund's
performance over time.  The table is supplemented as follows:

</TABLE>

The fund commenced investment operations on February 26, 1992 with the offering
of class A shares, and subsequently offered class I shares on January 2, 1997.
Class I share performance includes the performance of the fund's class A shares
for periods prior to the offering of class I shares. This blended class I share
performance has been adjusted to take into account the fact that class I shares
have no initial sales charge (load). This blended performance has not been
adjusted to take into account differences in class specific operating expenses.
Because operating expenses of class I shares are lower than those of class A
shares, this blended class I share performance is lower than the performance of
class I shares would have been had class I shares been offered for the entire
period.

2.       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:

         ANNUAL FUND OPERATING EXPENSES (EXPENSES THAT ARE DEDUCTED FROM FUND
ASSETS):

            Management Fees                                     0.40%
            Distribution and Service (12b-1) Fees               0.00%
            Other Expenses (1)                                  0.28%
            Total Annual Fund Operating Expenses                0.68%
- --------------------------
(1)  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. "Other Expenses" do not
     take into account these expense reductions, and therefore do not represent
     the actual expenses of the fund.

3.       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;

        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.

        The table is supplemented as follows:

                SHARE CLASS        YEAR 1       YEAR 3      YEAR 5      YEAR 10
                -----------        ------       ------      ------      -------

               Class I shares       $69         $218        $379         $847

4.       DESCRIPTIONS 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 the 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;

         o  any fund distributed by MFS, if the fund seeks to achieve its
            investment objective by investing primarily in shares of the 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 fund's policies, disqualify the purchaser as an eligible investor in
class I shares.

5.       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
- ----------------------

o   INVESTMENT OBJECTIVE


    The fund's main investment objective is to provide as high a level of
    current income as is believed to be consistent with prudent investment
    risk. Its secondary objective is to protect shareholders' capital. The
    fund's objectives 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 fixed income securities with "limited" maturities
    (generally securities with remaining maturities of 5 years or less). These
    securities may include:

    o corporate bonds, which are bonds or other debt obligations issued by
      domestic or foreign (including emerging market) corporations or similar
      entities,

    o mortgage-backed and asset-backed securities, which represent interests in
      a pool of assets such as mortgage loans, car loan receivables, or credit
      card receivables, and

    o U.S. government securities, which are bonds or other debt obligations
      issued by, or whose principal and interest payments are guaranteed or
      supported by, the U.S. government or one of its agencies or
      instrumentalities (including mortgage-backed securities).

      Fixed income securities with limited maturities may include:

    o securities with remaining maturities of 5 years or less,

    o securities with estimated remaining average lives of 5 years or less, and

    o securities with a "duration" of 5 years or less (the fund determines the
      duration of a fixed income security by taking the present value of all its
      future principal and interest payments and calculating the dollar-weighted
      average time until those payments will be received).


      The fund only purchases investment grade bonds, which are bonds rated in
    the higher rating categories by credit rating agencies or unrated and
    considered by MFS to be comparable in quality. The fund's dollar-weighted
    average quality is within the three highest rating categories by credit
    rating agencies. The fund's investments in securities of foreign issuers
    are U.S. dollar denominated.


      In selecting fixed income investments for the fund, MFS considers the
    views of its large group of fixed income portfolio managers and research
    analysts. This group periodically assesses the three-month total return
    outlook for various segments of the fixed income markets. This three-month
    "horizon" outlook is used by the portfolio manager(s) of MFS' fixed income
    oriented funds (including the fund) as a tool in making or adjusting a
    fund's asset allocations to various segments of the fixed income markets.
    In assessing the credit quality of fixed income securities, MFS does not
    rely solely on the credit ratings assigned by credit rating agencies, but
    rather performs its own independent credit analysis.

o   PRINCIPAL RISKS OF AN INVESTMENT


    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 would cause the value of your investment in
    the fund to decline, and which would prevent the fund from achieving its
    objective, that are not described here.


      The principal risks of investing in the fund are:

    o 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.

    o Maturity Risk: 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.

    o Allocation Risk: The fund will allocate its investments among various
      segments of the fixed income markets based upon judgments made by MFS. The
      fund could miss attractive investment opportunities by underweighting
      markets where there are significant returns, and could lose value by
      overweighting markets where there are significant declines.

    o 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.

    o 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 Mortgage and Asset-Backed Securities:

      > Maturity Risk:

        + Mortgage-Backed Securities: A mortgage-backed security will mature
          when all the mortgages in the pool mature or are prepaid. Therefore,
          mortgage-backed securities do not have a fixed maturity, and their
          expected maturities may vary when interest rates rise or fall.


          > When interest rates fall, homeowners are more likely to prepay their
            mortgage loans. An increased rate of prepayments on the fund's
            mortgage-backed securities will result in an unforeseen loss of
            interest income to the fund as the fund may be required to reinvest
            assets at a lower interest rate. Because prepayments increase when
            interest rates fall, the price of mortgage-backed securities does
            not increase as much as other fixed income securities when interest
            rates fall.


          > When interest rates rise, homeowners are less likely to prepay their
            mortgage loans. A decreased rate of prepayments lengthens the
            expected maturity of a mortgage-backed security. Therefore, the
            prices of mortgage-backed securities may decrease more than prices
            of other fixed income securities when interest rates rise.

        + Collateralized Mortgage Obligations: The fund may invest in
          mortgage-backed securities called collateralized mortgage obligations
          (CMOs). CMOs are issued in separate classes with different stated
          maturities. As the mortgage pool experiences prepayments, the pool
          pays off investors in classes with shorter maturities first. By
          investing in CMOs, the fund may manage the prepayment risk of
          mortgage-backed securities. However, prepayments may cause the actual
          maturity of a CMO to be substantially shorter than its stated
          maturity.

        + Asset-Backed Securities: Asset-backed securities have prepayment risks
          similar to mortgage-backed securities.

      > Credit Risk: As with any fixed income security, mortgage-backed and
        asset- backed securities are subject to the risk that the issuer will
        default on principal and interest payments. It may be difficult to
        enforce rights against the assets underlying mortgage-backed and
        asset-backed securities in the case of default. The U.S. government or
        its agencies may guarantee the payment of principal and interest on some
        mortgage-backed securities. Mortgage- backed securities and asset-backed
        securities issued by private lending institutions or other financial
        intermediaries may be supported by insurance or other forms of
        guarantees.


    o Foreign Markets Risk: Investments in securities of foreign issuers 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.

    o Active or Frequent Trading Risk: The fund has engaged and may engage in
      active and frequent trading to achieve its 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.

    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 below are intended to indicate some of
    the risks of investing in the fund by showing changes in the fund's
    performance over time. The performance table also shows how the fund's
    performance over time compares with that of one or more broad measures of
    market performance. The chart and table provide past performance
    information. The fund's past performance does not necessarily indicate how
    the fund will perform in the future. The performance information in the
    chart and table is based upon calendar year periods, while the performance
    information presented under the caption "Financial Highlights" and in the
    fund's shareholder reports is based upon the fund's fiscal year.
    Therefore, these performance results differ.

    BAR CHART


    The bar chart shows changes in the annual total returns of the fund's
    class A shares for each complete calendar year since the fund's inception.
    The chart and related notes do not take into account any sales charges
    (loads) that you may be required to pay upon purchase or redemption of the
    fund's shares, but do include the reinvestment of distributions. Any sales
    charge will reduce your return. The return of the fund's other classes of
    shares will differ from the class A returns shown in the bar chart,
    depending upon the expenses of those classes.

               1998                       5.12%

      The total return for the fund's class A shares for the three month
    period ended March 31, 1999 was 0.99%.


      During the period shown in the bar chart, the highest quarterly return
    was 4.01% (for the calendar quarter ended June 30, 1995) and the lowest
    quarterly return was (0.76)% (for the calendar quarter ended March 31,
    1994).


    PERFORMANCE TABLE

    This table shows how the average annual total returns of each class of the
    fund compare to a broad measure of market performance and various other
    market indicators and assumes the reinvestment of distributions.

    ** The Lehman Brothers One- to Three-Year Government/Corporate Bond Index is
       a broad based total return index consisting of all U.S. government
       agency, Treasury securities, and all investment-grade corporate debt
       securities with maturities of one to three years.

    Class A share performance takes into account the deduction of the 2.50%
    maximum sales charge. Class B share performance takes into account the
    deduction of the applicable contingent deferred sales charge (referred to
    as a CDSC), which declines over six years from 4% to 0%. Class C share
    performance takes into account the deduction of the 1% CDSC.


      The fund commenced investment operations on February 26, 1992 with the
    offering of class A shares and subsequently offered class B shares on
    September 7, 1993, and class C shares on July 1, 1994. Class B and class C
    share performance include the performance of the fund's class A shares for
    periods prior to the offering of class B and class C shares. This blended
    class B and class C share performance has been adjusted to take into
    account the CDSC applicable to class B and class C shares, rather than the
    initial sales charge (load) applicable to class A shares. This blended
    performance has not been adjusted to take into account differences in
    class specific operating expenses. Because operating expenses of class B
    and C shares are higher than those of class A shares, this blended class B
    and C share performance is higher than the performance of class B and C
    shares would have been had class B and C shares been offered for the
    entire period. If you would like the fund's current yield, contact the MFS
    Service Center at the toll free number set forth on the back cover page.

II EXPENSE SUMMARY
- ------------------

o   EXPENSE TABLE

    This table describes the fees and expenses that you may pay when you buy,
    redeem and hold shares of the fund.

    Other Expenses(3) ...........................    0.28%       0.28%    0.28%
                                                     -----       -----    -----
    Total Annual Fund Operating Expenses ........    0.83%       1.60%    1.68%

    --------
    (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) 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.
        "Other Expenses" do not take into account these expense reductions,
        and are therefore higher than the actual expenses of the fund.

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.

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

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

o   FURTHER INFORMATION ON INVESTMENT STRATEGIES AND RISKS

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

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

    The fund offers class A, B and C shares through this prospectus. The 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.

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                                2.50            2.56
    $50,000 but less than $100,000                   2.25            2.30
    $100,000 but less than $250,000                  2.00            2.04
    $250,000 but less than $500,000                  1.75            1.78
    $500,000 but less than $1,000,000                1.50            1.52
    $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 Fundamental 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 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

      > the plan has not redeemed its class B shares in the MFS funds in order
        to purchase class A shares under this category.

    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, a market value of $500,000 or
        more invested in shares of any class or classes of the MFS Funds.

        THE RETIREMENT PLAN WILL QUALIFY UNDER THIS CATEGORY ONLY IF THE PLAN OR
        ITS SPONSORING ORGANIZATION INFORMS MFSC PRIOR TO THE PURCHASES THAT THE
        PLAN HAS 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 A PLAN QUALIFIES UNDER THIS CATEGORY; 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, 1997;

      > the plan's 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. Three 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.

    o Purchases of class B shares prior to January 1, 1993 made on any day
      during a calendar year will age one year at the close of business on
      December 31 of that 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

    The 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. Payment of 0.10% of the class A
    service fee and the 0.10% per annum class A distribution fee is currently
    not being imposed and will be implemented on such date as the Trustees of
    the Trust may determine. Except in the case of the 0.25% per annum class B
    service fee paid by the fund upon the sale of class B shares in the first
    year, the class B service fee is currently set at 0.15% per annum and may
    be increased to a maximum of 0.25% per annum on such date as the Trustees
    of the Trust may determine.

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

    You may purchase, exchange and redeem class A, B and C shares of the 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 Fundamental 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, the 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. This privilege applies to shares of the MFS
    money market funds only under certain circumstances.

    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 the fund makes an in-kind
    distribution, you could incur the brokerage and transaction charges when
    converting the securities to cash. The fund does not expect to make in-
    kind distributions, and if it does, the fund 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.

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

    As a shareholder of the 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 the 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 Dividends and capital gain distributions reinvested in additional shares
      (this option will be assigned if no other option is specified);

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

    o Dividends 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. Dividends and capital gain
    distributions in amounts less than $10 will automatically be reinvested in
    additional shares of the fund. If you have elected to receive dividends and/
    or capital gain 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
    dividends and other distributions reinvested in additional shares. Your
    request to change a distribution option must be received by MFSC by the
    record date for a dividend or distribution in order to be effective for that
    dividend or 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.

    FREE CHECKWRITING. You may redeem your class A or class C shares by
    writing checks against your account. Checks must be for at least $500 and
    investments made by check must have been in your account for at least 15
    days before you can write checks against them. There is no charge for this
    service. To authorize your account for checkwriting, contact MFSC (see
    back cover page for address and phone number).

      Shares in your account equal in value to the amount of the check plus
    the applicable CDSC (if any) and any income tax required to be withheld
    (if any) are redeemed to cover the amount of the check. If your account
    value is not great enough to cover these amounts, your check will be
    dishonored.

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

o   PRICING OF FUND SHARES


    The price of each class of the 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). To determine net asset value, the 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
    the 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 the 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.

    The 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 the fund's shares may change on days
    when you will not be able to purchase or redeem the fund's shares.

o   DISTRIBUTIONS

    The fund intends to declare daily as dividends substantially all of its
    net income (excluding any realized net capital gains) and to pay these
    dividends to shareholders at least monthly. Any realized net capital gains
    are distributed 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 the fund may have
    on your particular tax situation.

    TAXABILITY OF DISTRIBUTIONS. As long as the fund qualifies for treatment
    as a regulated investment company (which it has in the past and intends to
    do in the future), 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 the 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.


    Fund distributions of net capital gains or net short-term gains or net
    short-term capital gains by the fund will reduce the 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.


    If you are neither a citizen nor a resident of the U.S., the 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 the fund. The 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 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. Prospective investors should read the
    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 FUND

    MFS may serve as the investment adviser to other funds which have similar
    investment goals and principal investment policies and risks to the fund,
    and which may be managed by the fund's portfolio manager(s). While the
    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   YEAR 2000 READINESS DISCLOSURE

    The fund could be adversely affected if the computer systems used by MFS,
    the fund's other service providers or the companies in which the fund
    invests do not properly process date-related information from and after
    January 1, 2000. MFS recognizes the importance of the Year 2000 issue and,
    to address Year 2000 compliance, created a separately funded Year 2000
    Program Management Office in 1996 comprised of a specialized staff
    reporting directly to MFS senior management. The Office, with the help of
    external consultants, is responsible for overall coordination, strategy
    formulation, communications and issue resolution with respect to Year 2000
    issues. While MFS systems will be tested for Year 2000 readiness before
    the turn of the century, there are significant systems interdependencies
    in the domestic and foreign markets for securities, the business
    environments in which companies held by the fund operate and in MFS' own
    business environment. MFS has been working with the fund's other service
    providers to identify and respond to potential problems with respect to
    Year 2000 readiness and to develop contingency plans. Year 2000 readiness
    is also one of the factors considered by MFS in its ongoing assessment of
    companies in which the fund invests. There can be no assurance, however,
    that these steps will be sufficient to avoid any adverse impact on the
    fund.

o   PROVISION OF ANNUAL AND SEMIANNUAL REPORTS

    To avoid sending duplicate copies of materials to households, only one
    copy of the fund's annual and semiannual report 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 be sent personally
    to that shareholder.

IX FINANCIAL HIGHLIGHTS
- -----------------------

    The financial highlights table is intended to help you understand the
    fund's financial performance for the past 5 years. Certain information
    reflects financial results for a single fund share. The total returns in
    the table represent the rate by which an investor would have earned (or
    lost) on an investment in the fund (assuming reinvestment of all
    distributions). This information has been audited by the fund's
    independent auditors, whose report, together with the fund's financial
    statements, are included in the fund's Annual Report to shareholders. The
    fund's Annual Report is available upon request by contacting MFSC (see
    back cover for address and telephone number). These financial statements
    are incorporated by reference into the SAI. The fund's independent
    auditors are Deloitte & Touche LLP.

    ----------
      # Per share data are based on average shares outstanding.

     ## 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. For fiscal years ending after
        September 1, 1995, the fund's expenses are calculated without reduction for this expense offset arrangement.


    (+) Total returns for Class A shares do not include the applicable sales charge. If the charge had been included,
        the results would have been lower.

     "Fund" - MFS Limited Maturity Fund, a diversified series of the Trust. The
     Fund was known as MFS Quality Limited Maturity Fund prior to August 3,
     1992.

     "MFS" or the "Adviser" - Massachusetts Financial Services Company, a
     Delaware corporation.

     "MFD" - MFS Fund Distributors, Inc., a Delaware corporation.

     "MFSC" - MFS Service Center, Inc., a Delaware corporation.

     "Prospectus" - The Prospectus of the Fund, dated September 1, 1999, as
     amended or supplemented from time to time.

II   MANAGEMENT OF THE FUND

     THE FUND
     The Fund is a diversified series of the Trust. The Trust is an open-end
     management investment company.

     TRUSTEES AND OFFICERS - IDENTIFICATION AND BACKGROUND
     The identification and background of the Trustees and officers of the Trust
     are set forth in Appendix A of this Part I.

     TRUSTEE COMPENSATION
     Compensation paid to the non-interested Trustees and to Trustees who are
     not officers of the Trust, for certain specified periods, is set forth in
     Appendix B of this Part I.

     AFFILIATED SERVICE PROVIDER COMPENSATION
     Compensation paid by the Fund to its affiliated service providers -- to
     MFS, for investment advisory and administrative services, and to MFSC, for
     transfer agency services -- for certain specified periods is set forth in
     Appendix C to this Part I.


     MFS had contractually agreed to bear expenses for the Fund, subject to
     reimbursement by the Fund, such that the Fund's "Other Expenses" shall not
     exceed more than 0.40% of the average daily net assets of the Fund during a
     current fiscal year. The payments made by MFS on behalf of the Fund under
     this arrangement are currently subject to reimbursement by the Fund to MFS,
     and are being accomplished by the payment of an expense reimbursement fee
     by the Fund to MFS. This fee is computed and paid monthly at a percentage
     of the Fund's average daily net assets for its current fiscal year, with a
     limitation that immediately after such payment the Fund's "Other Expenses"
     will not exceed the percentage set forth for that Fund. The obligation of
     MFS to bear the Fund's "Other Expenses" pursuant to this arrangement, and
     the Fund's obligation to pay the reimbursement fee to MFS, terminates on
     the earlier of the date on which payments made by the series equal the
     prior payment of such reimbursable expenses by MFS, or on February 28,
     2002.


III  SALES CHARGES AND DISTRIBUTION PLAN PAYMENTS

     SALES CHARGES
     Sales charges paid in connection with the purchase and sale of Fund shares
     for certain specified periods are set forth in Appendix D to this Part I,
     together with the Fund's schedule of dealer reallowances.

     DISTRIBUTION PLAN PAYMENTS
     Payments made by the Fund under the Distribution Plan for its most recent
     fiscal year end are set forth in Appendix D to this Part I.

IV   PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS
     Brokerage commissions paid by the Fund for certain specified periods, and
     information concerning purchases by the Fund of securities issued by its
     regular broker-dealers for its most recent fiscal year, are set forth in
     Appendix E to this Part I.

     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 Trustees (together with the Trustees of certain
     other MFS funds) have directed the Adviser to allocate a total of $53,050
     of commission business from certain MFS funds (including the Fund) to the
     Pershing Division of Donaldson Lufkin & Jenrette as consideration for the
     annual renewal of certain publications provided by Lipper Analytical
     Securities Corporation (which provides information useful to the Trustees
     in reviewing the relationship between the Fund and the Adviser).

V    SHARE OWNERSHIP
     Information concerning the ownership of Fund shares by Trustees and
     officers of the Trust as a group, by investors who control the Fund, if

VII  INVESTMENT TECHNIQUES, PRACTICES, RISKS AND RESTRICTIONS


     INVESTMENT TECHNIQUES, PRACTICES AND RISKS
     The investment objective and principal investment policies of the Fund are
     described in the Prospectus. In pursuing its investment objective and
     principal investment policies, the Fund may engage in a number of
     investment techniques and practices, which involve certain risks. These
     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
     limitation applies to these investment techniques and practices.


       o Lending of Portfolio Securities may not exceed 30% of the Fund's net
         assets.

     INVESTMENT RESTRICTIONS
     The Fund has adopted the following restrictions which cannot be changed
     without the approval of the holders of a majority of the 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).

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

       The Fund may not:

       (1) borrow money in an amount in excess of 33 1/3% of its gross assets,
           and then only as a temporary measure for extraordinary or emergency
           purposes, or pledge, mortgage or hypothecate an amount of its assets
           (taken at market value) in excess of 33 1/3% of its gross assets, in
           each case taken at the lower of cost or market value and subject to a
           300% asset coverage requirement (for the purpose of this restriction,
           collateral arrangements with respect to options, Futures Contracts,
           Options on Futures Contracts, foreign currency, forward foreign
           currency contracts and options on foreign currencies and payments of
           initial and variation margin in connection therewith are not
           considered a pledge of assets);

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

       (3) concentrate its investments in any particular industry, but if it is
           deemed appropriate for the achievement of its investment objectives,
           the Fund may invest up to 25% of its assets (taken at market value at
           the time of each investment), in securities of issuers in any one
           industry;

       (4) purchase or sell real estate (including limited partnership interests
           but excluding securities of companies, such as real estate investment
           trusts, which deal in real estate or interests therein), or mineral
           leases, commodities or commodity contracts (except options, Futures
           Contracts, Options on Futures Contracts, foreign currency, forward
           foreign currency contracts and options on foreign currencies) in the
           ordinary course of its business. The Fund reserves the freedom of
           action to hold and to sell real estate or mineral leases, commodities
           or commodity contracts (including options, Futures Contracts, Options
           on Futures Contracts, foreign currency, forward foreign currency
           contracts and options on foreign currencies) acquired as a result of
           the ownership of securities. The Fund will not purchase securities
           for the purpose of acquiring real estate or mineral leases,
           commodities or commodity contracts (except options, Futures
           Contracts, Options on Futures Contracts, foreign currency, forward
           foreign currency contracts and options on foreign currencies);

       (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 in accordance with its investment objectives
           and policies, the lending of portfolio securities, or the investment
           of the Fund's assets in repurchase agreements, shall not be
           considered the making of a loan;

       (6) invest for the purpose of exercising control or management;

       (7) purchase any securities or evidences of interest therein on margin,
           except to make deposits on margin in connection with options, Futures
           Contracts, Options on Futures Contracts, foreign currency, forward
           foreign currency contracts and options on foreign currencies, and
           except that the Fund may obtain such short-term credit as may be
           necessary for the clearance of purchases and sales of securities;

       (8) sell any security which the Fund does not own unless by virtue of its
           ownership of other securities the Fund has at the time of sale a
           right to obtain securities without payment of further consideration
           equivalent in kind and amount to the securities sold and provided
           that if such right is conditional the sale is made upon the same
           conditions; or

       (9) purchase or sell any put or call option or any combination thereof,
           provided, that this shall not prevent the purchase, ownership,
           holding or sale of warrants where the grantor of the warrants is the
           issuer of the underlying securities or the writing, purchasing and
           selling of puts, calls or combinations thereof with respect to
           securities, Futures Contracts and foreign currencies.


       In addition, the Fund has the following non-fundamental policies which
     may be changed without shareholder approval.

       (1) The Fund will not 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 unaudited securities where
           no market exists), unless the Board of Trustees has determined that
           such securities are liquid based on trading markets for the specific
           security, if more than 15% of the 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 the Fund's limitation on investment in illiquid
           securities.

       (2) Purchases of warrants will not exceed 5% of the Fund's net assets.
           Included within that amount, but not exceeding 2% of the Fund's net
           assets, may be warrants not listed on the New York or American Stock
           Exchange.

       (3) The Fund may not invest 25% or more of the market value of its total
           assets in securities of issuers in any one industry.

     STATE AND FEDERAL RESTRICTIONS: In order to comply with certain federal and
     state statutes and regulatory policies, as a matter of operating policy of
     the Fund, the Fund will not: (a) invest more than 5% of the Fund's total
     assets at the time of investment in unsecured obligations of issuers which,
     including predecessors, controlling persons, sponsoring entities, general
     partners and guarantors, have a record of less than three years' continuous
     business operation or relevant business experience; (b) purchase voting
     securities of any issuer if such purchase, at the time thereof, would cause
     more than 10% of the outstanding voting securities of such issuer to be
     held by the Fund; (c) purchase or retain in its portfolio any securities
     issued by an issuer any of whose officers, directors, trustees or security
     holders is an officer or Trustee of the Trust, or is an officer or Director
     of the Adviser if, after the purchase of the securities of such issuer by
     the Fund, one or more of such persons owns beneficially more than 1/2 of 1%
     of the shares or securities, or both, of such issuer, and such persons
     owning more than 1/2 of 1% of such shares or securities together own
     beneficially more than 5% of such shares or securities, or both.


       The investment policies described under "State and Federal Restrictions"
     are not fundamental and may be changed without shareholder approval.

       Except for investment restriction no. 1 and the Fund's non-fundamental
     policy on investing in illiquid securities, these investment restrictions
     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 policy.

    * From the commencement of the fund's investment operations on February 26, 1992.
    + Annualized, based upon the last distribution.
</TABLE>

    The Fund commenced investment operations on February 26, 1992 with the
    offering of class A shares and subsequently offered class B shares on
    September 7, 1993, class C shares on July 1, 1994, and class I shares on
    January 2, 1997. Class B and class C share performance include the
    performance of the Fund's class A shares for periods prior to the offering
    of class B and class C shares. This blended class B and class C share
    performance has been adjusted to take into account the CDSC applicable to
    class B and class C shares, rather than the initial sales charge (load)
    applicable to class A shares. This blended performance has not been
    adjusted to take into account differences in class specific operating
    expenses. Because operating expenses of class B and C shares are higher
    than those of class A shares, this blended class B and C share performance
    is higher than the performance of class B and C shares would have been had
    class B and C shares been offered for the entire period. If you would like
    the Fund's current yield, contact the MFS Service Center at the toll free
    number set forth on the back cover page of Part II of this SAI.

    Class I share performance includes the performance of the Fund's class A
    shares for periods prior to the offering of class I shares. Class I share
    performance generally would have been higher than class A share
    performance had class I shares been offered for the entire period, because
    operating expenses (e.g., distribution and service fees) attributable to
    class I shares are lower than those of class A shares. Class I share
    performance has been adjusted to take into account the fact that class I
    shares have no initial sales charge.

    Performance results include any applicable expense subsidies and waivers,
    which may cause the results to be more favorable.

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; 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; 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.

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 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.

          FUNDamental 401(k) Plan or another similar recordkeeping system made

            of the MFS Family of Funds and aggregate assets of at least $10
            million;


      provided, however, that the CDSC will not be waived (i.e., it will be
      imposed) (a) with respect to plans which establish an account with MFSC on
      or after November 1, 1997, in the event that the plan makes a complete

            provided, however, that the CDSC will not be waived (i.e., it will
            be imposed) in the event that there is a change in law or
            regulations which results in a material adverse change to the tax
            advantaged nature of the plan, or in the event that the plan and/or
            sponsoring organization: (i) becomes insolvent or bankrupt; (ii) is

  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

      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).

    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.

  PART II - APPENDIX C
- ------------------------


    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. 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. 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.

    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.

    ABSENCE OF RATING: Where no rating has been assigned or where a rating has
    been suspended or withdrawn, it may be for reasons unrelated to the
    quality of the issue. Should no rating be assigned, the reason may be one
    of the following:

        1.  An application for rating was not received or accepted.

        2.  The issue or issuer belongs to a group of securities or companies
            that are not rated as a matter of policy.

        3.  There is a lack of essential data pertaining to the issue or
            issuer.

        4.  The issue was privately placed, in which case the rating is not
            published in Moody's publications.

    Suspension or withdrawal may occur if new and material circumstances
    arise, the effects of which preclude satisfactory analysis; if there is no
    longer available reasonable up-to-date data to permit a judgment to be
    formed; if a bond is called for redemption; or for other reasons.

                        STANDARD & POOR'S RATINGS SERVICES

    AAA: An obligation rated AAA has the highest rating assigned by S&P. 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: 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.

    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. Securities are not meeting current obligations and
    are extremely speculative. DDD designates the highest potential for
    recovery of amounts outstanding on any securities involved. For U.S.
    corporates, for example, DD indicates expected recovery of 50% -- 90% of
    such outstandings, 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.

  I  RISK RETURN SUMMARY

o   INVESTMENT OBJECTIVE

    The fund's investment objective is to provide as high a level of current
    income exempt from federal income taxes as is considered consistent with
    prudent investing while seeking protection of shareholders' capital. The
    fund's objective may be changed without shareholder approval.

o   PRINCIPAL INVESTMENT POLICIES


    The fund invests, under normal market conditions, at least 80% of its
    total assets in municipal securities and participation interests in
    municipal securities with "limited" maturities that are issued by banks,
    the interest on which is exempt from federal income tax. Municipal
    securities are bonds or other debt obligations of a U.S. state or
    political subdivision, such as a county, city, town, village, or
    authority. Participation interests in municipal securities are interests
    in holdings of municipal obligations backed by a letter of credit or
    guarantee from the issuing bank. The fund seeks to invest in municipal
    securities whose income is exempt from federal personal income taxes.
    However, the interest income on certain of these municipal securities may
    be subject to an alternative minimum tax. For a comparison of yields on
    municipal bonds and taxable securities, see the Tax Equivalent Yield Table
    attached as Appendix B to this Prospectus.


      Under normal market conditions, substantially all of the fund's total
    assets will be invested in municipal securities rated, or issued by
    issuers who have securities that are rated, in one of the top four credit
    ratings by credit rating agencies. The fund may also invest in tax-exempt
    securities that are not rated but which, in the opinion of the fund's
    investment adviser, Massachusetts Financial Services Company (referred to
    as MFS or the adviser), are of at least comparable quality to the four
    highest credit ratings.

      Fixed income securities with limited maturities may include:

      o   securities with remaining maturities of 5 years or less;

      o   securities with estimated remaining average lives of 5 years or less;
          and

      o   securities with a "duration" of 5 years or less (the fund determines
          the duration of a fixed income security by taking the present value of
          all its future principal and interest payments and calculating the
          dollar-weighted average time until those payments will be received)

    Under normal market conditions, the fund's dollar weighted average
    maturity will not exceed 5 years and substantially all of the securities
    held by the fund will have remaining maturities of 10 years or less.

      In selecting fixed income investments for the fund, MFS considers the
    views of its large group of fixed income portfolio managers and research
    analysts. This group periodically assesses the three-month total return
    outlook for various segments of the fixed income markets. This three-month
    "horizon" outlook is used by the portfolio manager(s) of MFS' fixed income
    oriented funds (including the fund) as a tool in making or adjusting a
    fund's asset allocation to various segments of the fixed income markets.
    In assessing the credit quality of fixed income securities, MFS does not
    rely solely on the credit ratings assigned by credit rating agencies, but
    rather performs its own independent credit analysis.

o   PRINCIPAL RISKS OF AN INVESTMENT


    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 Municipal Securities Risk

       |> Interest Rate Risk: As with any fixed income security, the prices of
          municipal securities in the fund's portfolio will generally fall when
          interest rates rise. Conversely, when interest rates fall, the prices
          of municipal securities in the fund's portfolio will generally rise.

       |> Maturity Risk: Municipal securities with shorter maturities will be
          less volatile but generally provide lower returns than municipal
          securities with longer maturities. The average maturity of the fund's
          municipal security investments will affect the volatility of the
          fund's share price.

       |> Credit Risk: Credit risk is the risk that the issuer of a municipal
          security will not be able to pay principal and interest when due.
          Rating agencies assign credit ratings to certain municipal securities
          to indicate their credit risk. The price of a municipal 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. A participation interest is also subject to the
          risk of default by the issuing bank.

       |> General Obligations and Revenue Obligations Risk: The fund may invest
          in municipal bonds that are general obligations backed by the full
          faith and credit of the municipal issuer. The fund may also invest in
          municipal bonds called revenue obligations which are subject to a
          higher degree of credit risk than general obligations. Revenue
          obligations finance specific projects, such as building a hospital,
          and are not backed by the full faith and credit of the municipal
          issuer. Because revenue obligations are repaid from the revenues from
          a facility, they are subject to a risk of default in payments of
          principal and interest if the facility does not generate enough
          income.

    o Speculative Bonds Risk: Bonds rated in the lowest investment grade
      category (i.e. bonds receiving the fourth highest credit rating) by credit
      rating agencies are called speculative bonds. Speculative bonds are
      subject to a higher risk that the issuer will default on payments of
      principal and interest than higher rated investment grade bonds. Although
      the issuer's ability to make interest and principal payments appears
      adequate, an adverse change in economic conditions or other circumstances
      is more likely to cause a default by the issuer of a speculative bond than
      the issuer of a higher rated investment grade bond. If a security
      purchased by the fund is downgraded below investment grade, the security
      will be sold only if the Adviser believes it is advantageous to do so.

    o 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 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 below are intended to indicate some of
    the risks of investing in the fund by showing changes in the fund's
    performance over time. The performance table also shows how the fund's
    performance over time compares with that of one or more broad measures of
    market performance. The chart and table provide past performance
    information. The fund's past performance does not necessarily indicate how
    the fund will perform in the future. The performance information in the
    chart and table is based upon calendar year periods, while the performance
    information presented under the caption "Financial Highlights" and in the
    fund's shareholder reports is based upon the fund's fiscal year.
    Therefore, these performance results differ.


    BAR CHART

    The bar chart shows changes in the annual total returns of the fund's
    class A shares for each calendar year since class A shares were first
    offered. The chart and related notes do not take into account any sales
    charges (loads) that you may be required to pay upon purchase or
    redemption of the fund's shares, but do include the reinvestment of
    distributions. Any sales charge will reduce your return. The return of the
    fund's other classes of shares will differ from the class A returns shown
    in the bar chart, depending upon the expenses of those classes.


                    1993                7.91%
                    1994               (1.27)%
                    1995                8.03%
                    1996                2.87%
                    1997                4.85%
                    1998                4.44%


      The total return for the fund's class A shares for the three month
    period ended March 31, 1999 was 0.69%. During the period shown in the bar
    chart, the highest quarterly return was 2.46% (for the calendar quarter
    ended March 31, 1995) and the lowest quarterly return was (2.71)% (for the
    calendar quarter ended March 31, 1994).

    PERFORMANCE TABLE

    This table shows how the average annual total returns of each class of the
    fund compares to two broad measures of market performance and the average
    short-term municipal bond fund and assumes the reinvestment of
    distributions.

    Class A share performance takes into account the deduction of the 2.50%
    maximum sales charge. Class B share performance takes into account the
    deduction of the applicable contingent deferred sales charge (referred to
    as a CDSC), which declines over six years from 4% to 0%.

    The fund commenced investment operations on March 17, 1992 with the
    offering of class A shares and subsequently offered class B shares on
    September 7, 1993 and class C shares on July 1, 1994. Class B share
    performance includes the performance of the fund's class A shares for
    periods prior to the offering of class B shares. This blended class B
    share performance has been adjusted to take into account the CDSC
    applicable to class B shares, rather than the initial sales charge (load)
    applicable to class A shares. This blended performance has not been
    adjusted to take into account differences in class specific operating
    expenses. Because operating expenses of class B shares are higher than
    those of class A shares, this blended class B share performance is higher
    than the performance of class B shares would have been had class B been
    offered for the entire period.

    Net Expenses ............................    0.88%      1.66%     1.73%

    ------
    (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 B and C shares and the services provided to you by your
        financial adviser (referred to as distribution and service fees).
    (3) 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.
        "Other Expenses" do not take into account these expense reductions,
        and are therefore higher than the actual expenses of the fund.
    (4) MFS has contractually agreed to waive its right to receive 0.10% of
        the management fee annually. This contractual fee arrangement will
        remain in effect until at least September 1, 2000, absent an earlier
        modification approved by the board of trustees which oversees the
        fund.

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 Expense Table).


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

    SHARE CLASS                          YEAR 1     YEAR 3    YEAR 5   YEAR 10
    --------------------------------------------------------------------------
    Class A shares                        $338       $545     $  769    $1,412
    Class B shares
      Assuming redemption at end of
       period                             $569       $844     $1,145    $1,859
      Assuming no redemption              $169       $544     $  945    $1,859
    Class C shares
      Assuming redemption at end of
       period                             $276       $566     $  981    $2,140
      Assuming no redemption              $176       $566     $  981    $2,140

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

o   FURTHER INFORMATION ON INVESTMENT STRATEGIES AND RISKS

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

o   ACTIVE OR FREQUENT TRADING

    The fund may engage in active and frequent trading to achieve its
    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 FUND
  --------------------------

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 $113.4 billion on behalf of
    approximately 4.6 million investor accounts as of July 31, 1999. As of
    such date, the MFS organization managed approximately $6.4 billion of net
    assets in municipal bond securities. Approximately $21.6 billion of the
    assets managed by MFS are invested in fixed income securities. MFS is
    located at 500 Boylston Street, Boston, Massachusetts 02116.

    MFS provides investment management and related administrative services and
    facilities to the fund, including portfolio management and trade
    execution. For these services, the fund pays MFS an annual management fee
    computed and paid monthly, at the rate of 0.40% per annum of the average
    daily net assets of the fund. MFS has agreed to waive its right to receive
    a portion of this fee as described under "Expense Summary."

    For the fiscal year ended April 30, 1999, the fund paid the adviser a
    management fee equivalent to .30% per annum of the fund's average daily
    net asset value.


o   PORTFOLIO MANAGER


    The fund's portfolio manager is Christopher J. Mier, a Senior Vice
    President of MFS. Mr. Mier has been the portfolio manager of the fund
    since May 1, 1999 and has been employed as a portfolio manager by MFS
    since April 1999. Prior to April 1999, Mr. Mier spent 13 years as a
    managing director and portfolio manager in the municipal bond department
    at Scudder Kemper Investments, Inc.


o   ADMINISTRATOR

    MFS provides the fund with certain financial, legal, compliance,
    shareholder communications and other administrative services. MFS is
    reimbursed by the fund for a portion of the costs it incurs in providing
    these services.

o   DISTRIBUTOR

    MFS Fund Distributors, Inc. (referred to as MFD), a wholly owned
    subsidiary of MFS, is the distributor of shares of the fund.

o   SHAREHOLDER SERVICING AGENT

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


    The fund offers class A, B and C shares through this prospectus.


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.

    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:

    *  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 Fundamental 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 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

       |> the plan has not redeemed its class B shares in the MFS Funds in order
          to purchase class A shares under this category.

    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, a market value of $500,000 or
          more invested in shares of any class or classes of the MFS Funds.

          THE RETIREMENT PLAN WILL QUALIFY UNDER THIS CATEGORY ONLY IF THE PLAN
          OR ITS SPONSORING ORGANIZATION INFORMS MFSC PRIOR TO THE PURCHASES
          THAT THE PLAN HAS 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 A PLAN QUALIFIES
          UNDER THIS CATEGORY; 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, 1997;

       |> the plan's 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. Three 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.

    o  Purchases of class B shares prior to January 1, 1993 made on any day
       during a calendar year will age one year at the close of business on
       December 31 of that 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


    The 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. Payment of
    0.10% of the class A service fee is currently not being imposed and will
    be implemented on such date as the Trustees of the Trust may determine.
    Payment of the 0.10% per annum class A distribution fee is currently not
    being imposed and will be implemented on such date as the Trustees of the
    Trust may determine. Except in the case of the 0.25% per annum class B
    service fee paid by the fund upon the sale of class B shares in the first
    year, the class B service fee has been set at 0.15% per annum and may be
    increased to a maximum of 0.25% per annum on such date as the Trustees of
    the Trust may determine. Over time, these fees will increase the cost of
    your shares and may cost you more than paying other types of sales
    charges.


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

    You may purchase, exchange and redeem class A, B and C shares of the 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 Fundamental 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, the 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. This privilege applies to shares of the MFS
    money market funds only under certain circumstances.

    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 the fund makes an in-kind
    distribution, you could incur the brokerage and transaction charges when
    converting the securities to cash. The fund does not expect to make in-
    kind distributions, and if it does, the fund 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.

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

    As a shareholder of the 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 the 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  Dividends and capital gain distributions reinvested in additional shares
       (this option will be assigned if no other option is specified);

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

    o  Dividends 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. Dividends and capital gain
    distributions in amounts less than $10 will automatically be reinvested in
    additional shares of the fund. If you have elected to receive dividends
    and/or capital gain 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 dividends and other distributions reinvested in
    additional shares. Your request to change a distribution option must be
    received by MFSC by the record date for a dividend or distribution in
    order to be effective for that dividend or 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.

    FREE CHECKWRITING. You may redeem your class A or class C shares by
    writing checks against your account. Checks must be for at least $500 and
    investments made by check must have been in your account for at least 15
    days before you can write checks against them. There is no charge for this
    service. To authorize your account for checkwriting, contact MFSC (see
    back cover page for address and phone number).

    Shares in your account equal in value to the amount of the check plus the
    applicable CDSC (if any) and any income tax required to be withheld (if
    any) are redeemed to cover the amount of the check. If your account value
    is not great enough to cover these amounts, your check will be dishonored.

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

o   PRICING OF FUND SHARES


    The price of each class of the 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). To determine net asset value, the 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
    the 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 the 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.

o   DISTRIBUTIONS

    The fund intends to declare daily as dividends substantially all of its
    net income (excluding any realized net capital gains) and to pay these
    dividends to shareholders at least monthly. Any realized net capital gains
    are distributed 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 the fund may have
    on your particular tax situation.

    TAXABILITY OF DISTRIBUTIONS. As long as the fund qualifies for treatment
    as a regulated investment company (which it has in the past and intends to
    do in the future), it pays no federal income tax on the earnings it
    distributes to shareholders.

    You may receive three different types of distributions from the fund:
    exempt-interest dividends, ordinary dividends and capital gain dividends.
    Most distributions will be exempt-interest dividends, which are exempt
    from federal income tax, but may be subject to state or local income
    taxes. Ordinary dividends are normally subject to both federal income tax
    and any state or local income taxes. Distributions designated as capital
    gain dividends are taxable as long-term capital gains. Any taxes that you
    pay on a distribution will be the same whether you take the distribution
    in cash or have it reinvested in additional shares of the fund. 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.


    Fund distributions of net capital gains or net short-term capital gains by
    the fund will reduce the 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.


    If you are neither a citizen nor a resident of the U.S., the 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 the fund. The 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 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. Prospective investors should read the
    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.

    OTHER TAX ISSUES. Exempt-interest dividends that you receive may affect
    your alternative minimum tax calculation. Also, if you are receiving
    social security or railroad retirement benefits, your exempt-interest
    dividends may increase the tax on your benefits. If you borrow money to
    purchase or carry shares of the fund, your deduction for interest paid on
    those borrowings will be limited.

o   UNIQUE NATURE OF FUND

    MFS may serve as the investment adviser to other funds which have similar
    investment goals and principal investment policies and risks to the fund,
    and which may be managed by the fund's portfolio manager(s). While the
    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   YEAR 2000 READINESS DISCLOSURE

    The fund could be adversely affected if the computer systems used by MFS,
    the fund's other service providers or the companies in which the fund
    invests do not properly process date-related information from and after
    January 1, 2000. MFS recognizes the importance of the Year 2000 issue and,
    to address Year 2000 compliance, created a separately funded Year 2000
    Program Management Office in 1996 comprised of a specialized staff
    reporting directly to MFS senior management. The Office, with the help of
    external consultants, is responsible for overall coordination, strategy
    formulation, communications and issue resolution with respect to Year 2000
    issues. While MFS systems will be tested for Year 2000 readiness before
    the turn of the century, there are significant systems interdependencies
    in the domestic and foreign markets for securities, the business
    environments in which companies held by the fund operate and in MFS' own
    business environment. MFS has been working with the fund's other service
    providers to identify and respond to potential problems with respect to
    Year 2000 readiness and to develop contingency plans. Year 2000 readiness
    is also one of the factors considered by MFS in its ongoing assessment of
    companies in which the fund invests. There can be no assurance, however,
    that these steps will be sufficient to avoid any adverse impact on the
    fund.

o   PROVISION OF ANNUAL AND SEMIANNUAL REPORTS

    To avoid sending duplicate copies of materials to households, only one
    copy of the fund's annual and semiannual report 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 be sent personally
    to that shareholder.

  IX FINANCIAL HIGHLIGHTS
  -----------------------

    The financial highlights table is intended to help you understand the
    fund's financial performance for the past 5 years. Certain information
    reflects financial results for a single fund share. The total returns in
    the table represent the rate by which an investor would have earned (or
    lost) on an investment in the fund (assuming reinvestment of all
    distributions). This information has been audited by the fund's
    independent auditors, whose report, together with the fund's financial
    statements, are included in the fund's Annual Report to shareholders. The
    fund's Annual Report is available upon request by contacting MFSC (see
    back cover for address and telephone number). These financial statements
    are incorporated by reference into the SAI. The fund's independent
    auditors are Deloitte & Touche LLP.

I    DEFINITIONS

     "Trust" - MFS Series Trust IX, a Massachusetts business trust organized in
     1985. The Trust was known as MFS Fixed Income Trust prior to January 18,
     1995, and as Massachusetts Financial Bond Fund until its name was changed
     on January 7, 1992.

     "Fund" - MFS Municipal Limited Maturity Fund, a diversified series of the
     Trust. The Fund is the successor to MFS Municipal Limited Maturity Fund
     (formerly known as MFS Tax-Free Limited Maturity Fund until its name was
     changed on August 3, 1992) which was reorganized as a series of the Trust
     on September 7, 1993.

     "MFS" or the "Adviser" - Massachusetts Financial Services Company, a
     Delaware corporation.

     "MFD" - MFS Fund Distributors, Inc., a Delaware corporation.

     "MFSC" - MFS Service Center, Inc., a Delaware corporation.

     "Prospectus" - The Prospectus of the Fund, dated September 1, 1999, as
     amended or supplemented from time to time.

II   MANAGEMENT OF THE FUND

     THE FUND
     The Fund is a diversified series of the Trust. The Trust is an open-end
     management investment company.

     TRUSTEES AND OFFICERS - IDENTIFICATION AND BACKGROUND
     The identification and background of the Trustees and officers of the
     Trust are set forth in Appendix A of this Part I.

     TRUSTEE COMPENSATION
     Compensation paid to the non-interested Trustees and to Trustees who are
     not officers of the Trust, for certain specified periods, is set forth in
     Appendix B of this Part I.

     AFFILIATED SERVICE PROVIDER COMPENSATION
     Compensation paid by the Fund to its affiliated service providers -- to
     MFS, for investment advisory and administrative services, and to MFSC, for
     transfer agency services -- for certain specified periods is set forth in
     Appendix C to this Part I.


       MFS had contractually agreed to bear expenses for the series, subject to
     reimbursement by the series, such that the series' "Other Expenses" shall
     not exceed more than 0.40% of the average daily net assets of the series
     during a current fiscal year. The payments made by MFS on behalf of the
     series under this arrangement are currently subject to reimbursement by the
     series to MFS, and are being accomplished by the payment of an expense
     reimbursement fee by the series to MFS. This fee is computed and paid
     monthly at a percentage of the series' average daily net assets for its
     current fiscal year, with a limitation that immediately after such payment
     the series' "Other Expenses" will not exceed the percentage set forth above
     for that series. The obligation of MFS to bear a series' "Other Expenses"
     pursuant to this arrangement, and the series' obligation to pay the
     reimbursement fee to MFS, terminates on February 28, 2002.

VII  INVESTMENT TECHNIQUES, PRACTICES, RISKS AND RESTRICTIONS

     INVESTMENT TECHNIQUES, PRACTICES AND RISKS
     The investment objective and principal investment policies of the Fund are
     described in the Prospectus. In pursuing its investment objective and
     principal investment policies, the Fund may engage in a number of
     investment techniques and practices, which involve certain risks. These
     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 apply to these investment techniques and practices.

       o The Fund may not lend more than 30% of its net assets.

     INVESTMENT RESTRICTIONS
     The Fund has adopted the following restrictions which cannot be changed
     without the approval of the holders of a majority of the 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).

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

       The Fund may not:


       (1) borrow money in an amount in excess of 33 1/3% of its gross assets,
           and then only as a temporary measure for extraordinary or emergency
           purposes, or pledge, mortgage or hypothecate an amount of its assets
           (taken at market value) in excess of 33 1/3% of its gross assets, in
           each case taken at the lower of cost or market value and subject to a
           300% asset coverage requirement (for the purpose of this restriction,
           collateral arrangements with respect to options, Futures Contracts,
           Options on Futures Contracts, foreign currency, forward foreign
           currency contracts and options on foreign currencies and payments of
           initial and variation margin in connection therewith are not
           considered a pledge of assets);


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

       (3) concentrate its investments in any particular industry, but if it is
           deemed appropriate for the achievement of its investment objectives,
           the Fund may invest up to 25% of its assets (taken at market value at
           the time of each investment) in securities of issuers in any one
           industry;


       (4) purchase or sell real estate (including limited partnership interests
           but excluding Municipal Bonds secured by real estate or interests
           therein), or mineral leases, commodities or commodity contracts
           (except options, Futures Contracts, Options on Futures Contracts,
           foreign currency, forward foreign currency contracts and options on
           foreign currencies) in the ordinary course of its business. The Fund
           reserves the freedom of action to hold and to sell real estate or
           mineral leases, commodities or commodity contracts (including
           options, Futures Contracts, Options on Futures Contracts, foreign
           currency, forward foreign currency contracts and options on foreign
           currencies) acquired as a result of the ownership of securities;

       (5) make loans to other persons except through the lending of the Fund's
           portfolio securities in accordance with, and to the extent permitted
           by, its investment objectives and policies, and except further that
           the Fund may enter into repurchase agreements. For these purposes the
           purchase of commercial paper or all or a portion of an issue of debt
           securities which are part of an issue to the public shall not be
           considered the making of a loan;


       (6) purchase any securities or evidences of interest therein on margin,
           except to make deposits on margin in connection with options, Futures
           Contracts, Options on Futures Contracts, foreign currency, forward
           foreign currency contracts and options on foreign currencies, and
           except that the Fund may obtain such short-term credit as may be
           necessary for the clearance of purchases and sales of securities; or

       (7) sell any securities which the Fund does not own unless by virtue of
           its ownership of other securities the Fund has at the time of sale a
           right to obtain securities without payment of further consideration
           equivalent in kind and amount to the securities sold and provided
           that if such right is conditional the sale is made upon the same
           conditions.


       In addition, the Fund has the following non-fundamental policies which
     may be changed without shareholder approval.

      (1) The Fund will not 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 the 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 the Fund's limitation on investment in
          illiquid securities. Securities that are not registered under the
          Securities Act of 1933, as amended, and sold in reliance on Rule
          144A thereunder, but are determined to be liquid by the Trust's
          Board of Trustees (or its delegate), will not be subject to this 15%
          limitation.

      (2) In addition, purchases of warrants will not exceed 5% of the Fund's
          net assets. Included within that amount, but not exceeding 2% of the
          Fund's net assets, may be warrants not listed on the New York or
          American Stock Exchange.

      (3) In addition, the Fund may not invest 25% or more of the market value
          of its total assets in securities of issuers in any one industry.

     Except with respect to Investment Restriction (1) and the Fund's policy on
     investing in illiquid securities, these investment restrictions 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 policy.

     For the purposes of the Fund's investment restrictions (including those
     listed below), the issuer of a tax-exempt security is deemed to be the
     entity (public or private) ultimately responsible for the payment of the
     principal of and interest on the security.

     STATE AND FEDERAL RESTRICTIONS: In order to comply with certain federal and
     state statutes and regulatory policies, as a matter of operating policy of
     the Fund, the Fund will not: (a) invest more than 5% of its total assets at
     the time of investment in unsecured obligations of issuers which, including
     predecessors, controlling persons, sponsoring entities, general partners
     and guarantors, have a record of less than three years' continuous business
     operation or relevant business experience; (b) purchase voting securities
     of any issuer if such purchase, at the time thereof, would cause more than
     10% of the outstanding voting securities of such issuer to be held by the
     Fund; (c) purchase or retain in its portfolio any securities issued by an
     issuer any of whose officers, directors, trustees or security holders is an
     officer or Trustee of the Trust, or is an officer or Director of the
     Adviser, if after the purchase of the securities of such issuer by the Fund
     one or more of such persons owns beneficially more than 1/2 of 1% of the
     shares or securities, or both, of such issuer, and such persons owning more
     than 1/2 of 1% of such shares or securities together own beneficially more
     than 5% of such shares or securities, or both; (d) invest for the purpose
     of exercising control or management; or (e) purchase or sell any put or
     call option or any combination thereof, provided, that this shall not
     prevent the purchase, ownership, holding or sale of warrants where the
     grantor of the warrants is the issuer of the underlying securities or the
     writing, purchasing and selling of puts, calls or combinations thereof with
     respect to securities, commodities, Futures Contracts and foreign
     currencies.


       The investment policies described under "State and Federal Restrictions"
     are not fundamental and may be changed without shareholder approval.

    * From the commencement of the fund's investment operations on March 17, 1992.
    + Annualized, based upon the last distribution.
</TABLE>

    The Fund commenced investment operations on March 17, 1992 with the
    offering of class A shares and subsequently offered class B shares on
    September 7, 1993 and class C shares on July 1, 1994. Class B and class C
    share performance include the performance of the Fund's class A shares for
    periods prior to the offering of class B and class C shares. This blended
    class B and class C share performance has been adjusted to take into
    account the CDSC applicable to class B and class C shares, rather than the
    initial sales charge (load) applicable to class A shares. This blended
    performance has not been adjusted to take into account differences in
    class specific operating expenses. Because operating expenses of class B
    and C shares are higher than those of class A shares, this blended class B
    and C share performance is higher than the performance of class B and C
    shares would have been had class B and C shares been offered for the
    entire period. If you would like the Fund's current yield, contact the MFS
    Service Center at the toll free number set forth on the back cover page of
    Part II of this SAI.

    Performance results include any applicable expense subsidies and waivers,
    which may cause the results to be more favorable.

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,

      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; 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; 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.

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 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.

      WAIVERS OF SALES CHARGES
      This Appendix sets forth the various circumstances in which all applicable
      sales charges are waived (Section I), the initial sales charge and the
      CDSC for Class A shares are waived (Section II), and the CDSC for Class B
      and Class C shares is waived (Section III). Some of the following
      information will not apply to certain funds in the MFS Family of Funds,

      financial planner and any other financial institutions having a selling
      agreement or other similar agreement with MFD.

        o Employees or registered representatives of dealers;


        o Certain family members of any such individual and their spouses or
          domestic partners identified above and certain trusts, pension,

          persons, provided the shares are not resold except to the MFS Fund
          which issued the shares; and


        o Institutional Clients of MFS or MFS Institutional Advisors, Inc.

            Funds. The sales charges will be waived in the case of a redemption
            of all of the 401(a) or ESP Plan's shares in all MFS Funds (i.e.,
            all the assets of the 401(a) or ESP Plan invested in the MFS Funds
            are withdrawn), unless immediately prior to the 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 Funds, in which case the sales
            charges will not be waived; and


          > Shares purchased by certain retirement plans or trust accounts if:
            (i) the plan is currently a party to a retirement plan recordkeeping
            or administration services agreement with MFD or one of its
            affiliates and (ii) the shares purchased or redeemed represent
            transfers from or transfers to plan investments other than the MFS
            Funds for which retirement plan recordkeeping services are provided
            under the terms of such agreement.

      Shares transferred:

          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, provided that the Plan sponsor subscribes to the MFS
          FUNDamental 401(k) Plan or another similar recordkeeping system made
          available by MFSC.

      LOAN REPAYMENTS
        o Shares acquired pursuant to repayments by retirement plan participants
          of loans from 401(a) or ESP Plans with respect to which such Plan or
          its sponsoring organization subscribes to the MFS FUNDamental 401(k)
          Program or the MFS Recordkeeper Plus Program (but not the MFS
          Recordkeeper Program).

II    WAIVERS OF CLASS A SALES CHARGES
      In addition to the waivers set forth in Section I above, in the following
      circumstances the initial sales charge imposed on purchases of Class A

            account with MFSC between July 1, 1996 and December 31, 1998;
            provided, however, that the CDSC will not be waived (i.e., it will
            be imposed) in the event that there is a change in law or
            regulations which results in a material adverse change to the tax
            advantaged nature of the plan, or in the event that the plan and/or
            sponsoring organization: (i) becomes insolvent or bankrupt; (ii) is
            terminated under ERISA or is liquidated or dissolved; or (iii) is

            establishment paperwork is received by MFSC in good order on or
            after November 15, 1998). A plan with a pre-existing account(s) with
            any MFS Fund which switches to the MFS Recordkeeper Plus product
            will not become eligible for this waiver category.

  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

      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).

    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. 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. 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.

    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.

    ABSENCE OF RATING: Where no rating has been assigned or where a rating has
    been suspended or withdrawn, it may be for reasons unrelated to the
    quality of the issue. Should no rating be assigned, the reason may be one
    of the following:

        1.  An application for rating was not received or accepted.

        2.  The issue or issuer belongs to a group of securities or companies
            that are not rated as a matter of policy.

        3.  There is a lack of essential data pertaining to the issue or
            issuer.

        4.  The issue was privately placed, in which case the rating is not
            published in Moody's publications.

    Suspension or withdrawal may occur if new and material circumstances
    arise, the effects of which preclude satisfactory analysis; if there is no
    longer available reasonable up-to-date data to permit a judgment to be
    formed; if a bond is called for redemption; or for other reasons.

                        STANDARD & POOR'S RATINGS SERVICES

    AAA: An obligation rated AAA has the highest rating assigned by S&P. 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: 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.

    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. Securities are not meeting current obligations and
    are extremely speculative. DDD designates the highest potential for
    recovery of amounts outstanding on any securities involved. For U.S.
    corporates, for example, DD indicates expected recovery of 50% -- 90% of
    such outstandings, 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.

          Supplement dated September 1, 1999 to the Current Prospectus

This Supplement describes the funds' class I shares, and it supplements certain
information in the funds' Prospectus dated September 1, 1999. 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 each fund. The table is
supplemented as follows:

     Annual Fund Operating Expenses (expenses that are deducted from fund
assets):

     Total Annual Fund Operating Expenses                       8.24%                   8.57%

- -----------------------
(1) 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.
    Each fund may enter into other similar arrangements and directed brokerage arrangements,
    which would also have the effect of reducing the fund's expenses. "Other Expenses" do not
    take into account these expense reductions, and therefore do not represent the actual
    expenses of a fund.

(2) MFS has contractually agreed to waive its management fee and to bear the fund's expenses such
    that "Other Expenses" do not exceed 0.00% annually. These contractual arrangements will
    continue until at least September 1, 2000, unless modified with the consent of the board of
    trustees, which oversees the fund.
</TABLE>

     EXAMPLE OF EXPENSES. The "Example of Expenses" table is intended to help
you compare the cost of investing in each 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 Expense Table).

     The table is supplemented as follows:


                             SHARE CLASS           YEAR 1          YEAR 3

              MFS Research Bond Fund                 $0            $1,736

2.   DESCRIPTIONS 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 the 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 the fund and other MFS
        funds.

In no event will a 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.

4.   FINANCIAL HIGHLIGHTS

     The "Financial Highlights" table is intended to help you understand the
fund's financial performance. It is supplemented as follows:

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

1:  MFS INTERMEDIATE INVESTMENT GRADE BOND FUND

o   INVESTMENT OBJECTIVE

    The fund's primary investment objective is to provide as high a level of
    current income as the investment adviser believes is consistent with
    prudent investment risk.  The fund's secondary objective is to protect
    shareholders' capital. The fund's objectives 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 investment grade fixed income securities with
    "intermediate" maturities (generally securities with remaining maturities
    of 10 years or less). These securities include:

    o investment grade fixed income securities, assigned one of the top four
      credit ratings by credit rating agencies (e.g., rated AAA, AA, A or BBB)
      or which are unrated and considered by the fund's investment adviser,
      Massachusetts Financial Services Company (referred to as MFS or the
      adviser), to be investment grade, including

      > corporate bonds, which are bonds or other debt obligations issued by
        domestic or foreign corporations or similar entities,

      > mortgage and asset-backed securities, which represent interests in a
        pool of assets such as mortgage loans, car loan receivables, or credit
        card receivables, and

    o U.S. government securities, which are bonds or other debt obligations
      issued by, or whose principal and interest payments are guaranteed or
      supported by, the U.S. government or one of its agencies or
      instrumentalities.

    Fixed income securities with intermediate maturities may include:

    o securities with remaining maturities of 10 years or less,

    o securities with estimated remaining lives of 10 years or less,

    o securities with a "duration" of 10 years or less (the fund determines the
      duration of a fixed income security by taking the present value of all its
      future principal and interest payments and calculating the dollar-weighted
      average time until those payments will be received).

      Under normal market conditions, the fund's average dollar-weighted
    maturity will be between 5 and 7 years.

      In selecting fixed income investments for the fund, MFS considers the
    views of its large group of fixed income portfolio managers and research
    analysts. This group periodically assesses the three-month total return
    outlook for various segments of the fixed income markets. This three-month
    "horizon" outlook is used by the portfolio manager(s) of MFS' fixed income
    oriented funds (including the fund) as a tool in making or adjusting a
    fund's asset allocations to various segments of the fixed income markets.
    In assessing the credit quality of fixed income securities, MFS does not
    rely solely on the credit ratings assigned by credit rating agencies, but
    rather performs its own independent credit analysis.

      The fund may invest up to 100% of its assets in dollar-denominated
    foreign fixed income securities.

      The fund may invest in derivative securities. Derivatives are securities
    whose value may be based on other securities, currencies, interest rates,
    or indices. Derivatives include:

    o futures and forward contracts,


    o options on futures contracts, securities and bond indices,


    o structured notes and indexed securities, and

    o swaps, caps, collars and floors.

      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 Allocation Risk: The fund will allocate its investments among various
      segments of the fixed income markets based upon judgments made by MFS. The
      fund could miss attractive investment opportunities by underweighting
      markets where there are significant returns, and could lose value by
      overweighting markets where there are significant declines.

    o 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.

    o 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.

    o 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.

    o 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 Mortgage and Asset-Backed Securities:

      > Maturity Risk:

        + Mortgage-Backed Securities: A mortgage-backed security will mature
          when all the mortgages in the pool mature or are prepaid. Therefore,
          mortgage-backed securities do not have a fixed maturity, and their
          expected maturities may vary when interest rates rise or fall.

          > When interest rates fall, homeowners are more likely to prepay their
            mortgage loans. An increased rate of prepayments on the fund's
            mortgage-backed securities will result in an unforeseen loss of
            interest income to the fund. Because prepayments increase when
            interest rates fall, the price of mortgage-backed securities does
            not increase as much as other fixed income securities when interest
            rates fall.

          > When interest rates rise, homeowners are less likely to prepay their
            mortgage loans. A decreased rate of prepayments lengthens the
            expected maturity of a mortgage-backed security. Therefore, the
            prices of mortgage-backed securities may decrease more than prices
            of other fixed income securities when interest rates rise.

        + Collateralized Mortgage Obligations: The fund may invest in
          mortgage-backed securities called collateralized mortgage obligations
          (CMOs). CMOs are issued in separate classes with different stated
          maturities. As the mortgage pool experiences prepayments the pool pays
          off investors in classes with shorter maturities first. By investing
          in CMOs, the fund may manage the prepayment risk of mortgage-backed
          securities. However, prepayments may cause the actual maturity of a
          CMO to be substantially shorter than its stated maturity.

        + Asset-Backed Securities: Asset-backed securities have prepayment risks
          similar to mortgage-backed securities.

      > Credit Risk: As with any fixed income security, mortgage-backed and
        asset- backed securities are subject to the risk that the issuer will
        default on principal and interest payments. It may be difficult to
        enforce rights against the assets underlying mortgage-backed and
        asset-backed securities in the case of default. The U.S. government or
        its agencies may guarantee the payment of principal and interest on some
        mortgage-backed securities. Mortgage- backed securities and asset-backed
        securities issued by private lending institutions or other financial
        intermediaries may be supported by insurance or other forms of
        guarantees.

    o Derivatives Risk

      > Hedging Risk: When a derivative is used as a hedge against an opposite
        position that the fund also holds, any loss generated by the derivative
        should be substantially offset by gains on the hedged investment, and
        vice versa. While hedging can reduce or eliminate losses, it can also
        reduce or eliminate gains.

      > Correlation Risk: When the fund uses derivatives to hedge, it takes the
        risk that changes in the value of the derivative will not match those of
        the asset being hedged. Incomplete correlation can result in
        unanticipated losses.

      > Investment Risk: When the fund uses derivatives as an investment vehicle
        to gain market exposure, rather than for hedging purposes, any loss on
        the derivative investment will not be offset by gains on another hedged
        investment. The fund is therefore directly exposed to the risks of that
        derivative. Gains or losses from derivative investments may be
        substantially greater than the derivative's original cost.

      > Availability Risk: Derivatives may not be available to the fund upon
        acceptable terms. As a result, the fund may be unable to use derivatives
        for hedging or other purposes.

      > Credit Risk: When the fund uses derivatives, it is subject to the risk
        that the other party to the agreement will not be able to perform.

    o Foreign Securities: Investments in foreign securities involve risks
      relating to political, social and economic development 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.

    o Active or Frequent Trading Risk: The fund may engage in active and
      frequent trading to achieve its 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.

    o Non-Diversified Status Risk: Because the fund may invest 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 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 RESEARCH BOND FUND

o   INVESTMENT OBJECTIVE

    The fund's investment objective is total return (high current income and
    long term growth of capital). 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 fixed income securities. These securities include:

    o U.S. investment grade corporate fixed income securities, which are bonds
      or other debt obligations issued by U.S. corporations or similar entities
      which are assigned one of the top four credit ratings by credit rating
      agencies (e.g. rated AAA, AA, A or BBB) or which are unrated and
      considered by MFS to be investment grade,

    o U.S. government securities, which are bonds or other debt obligations
      issued by, or whose principal and interest payments are guaranteed or
      supported by, the U.S. government or one of its agencies or
      instrumentalities, or municipal obligations,

    o U.S. high yield fixed income securities, commonly known as junk bonds,
      which are bonds assigned lower credit ratings by credit rating agencies or
      which are unrated and considered by MFS to be comparable to lower rated
      bonds,

    o foreign fixed income securities, which are bonds or other debt obligations
      issued by foreign governments, including emerging market governments, and
      other foreign or emerging market issuers,

    o mortgage-backed and asset-backed securities, which represent interests in
      a pool of assets such as mortgage loans, car loan receivables, or credit
      card receivables.


      A committee of fixed income research analysts selects portfolio
    securities for the fund. This committee includes investment analysts
    employed not only by MFS, but also by MFS International (U.K.) Limited, a
    wholly owned subsidiary of MFS. Each analyst is assigned to follow a
    distinct category of the fixed income securities markets. The committee
    allocates the fund's assets among the various categories described above,
    and then individual analysts select what they view as the securities best
    suited to achieve the fund's investment objective within their assigned
    category. The fund's assets may be allocated among some or all of the
    various categories of fixed income securities.


      The fund may invest in derivative securities. Derivatives are securities
    whose value may be based on other securities, currencies, interest rates,
    or indices. Derivatives include:

    o futures and forward contracts,

    o options on futures contracts, foreign currencies, securities and bond
      indices,

    o structured notes and indexed securities, and

    o swaps, caps, collars and floors.

      The fund is a non-diversified mutual fund. This means that the fund may
    invest a relatively high percentage or 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 Allocation Risk: The fund will allocate its investments among fixed income
      markets based upon judgments made by MFS. The fund could miss attractive
      investment opportunities by underweighting markets where there are
      significant returns, and could lose value by overweighting markets where
      there are significant declines.

    o 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.

    o 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.

    o 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.

    o 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 Junk Bond 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 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 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 Mortgage and Asset-Backed Securities:

      > Maturity Risk:

        + Mortgage-Backed Securities: A mortgage-backed security will mature
          when all the mortgages in the pool mature or are prepaid. Therefore,
          mortgage-backed securities do not have a fixed maturity, and their
          expected maturities may vary when interest rates rise or fall.

          > When interest rates fall, homeowners are more likely to prepay their
            mortgage loans. An increased rate of prepayments on the fund's
            mortgage-backed securities will result in an unforeseen loss of
            interest income to the fund. Because prepayments increase when
            interest rates fall, the price of mortgage-backed securities does
            not increase as much as other fixed income securities when interest
            rates fall.

          > When interest rates rise, homeowners are less likely to prepay their
            mortgage loans. A decreased rate of prepayments lengthens the
            expected maturity of a mortgage-backed security. Therefore, the
            prices of mortgage-backed securities may decrease more than prices
            of other fixed income securities when interest rates rise.

        + Collateralized Mortgage Obligations: The fund may invest in
          mortgage-backed securities called collateralized mortgage obligations
          (CMOs). CMOs are issued in separate classes with different stated
          maturities. As the mortgage pool experiences prepayments, the pool
          pays off investors in classes with shorter maturities first. By
          investing in CMOs, the fund may manage the prepayment risk of
          mortgage-backed securities. However, prepayments may cause the actual
          maturity of a CMO to be substantially shorter than its stated
          maturity.

          + Asset-Backed Securities: Asset-backed securities have prepayment
            risks similar to mortgage-backed securities.


      > Credit Risk: As with any fixed income security, mortgage-backed and
        asset- backed securities are subject to the risk that the issuer will
        default on principal and interest payments. It may be difficult to
        enforce rights against the assets underlying mortgage-backed and the
        asset-backed securities in the case of default. The U.S. government or
        its agencies may guarantee the payment of principal and interest on some
        mortgage-backed securities. Mortgage- backed securities and asset-backed
        securities issued by private lending institutions or other financial
        intermediaries may be supported by insurance or other forms of
        guarantees.


    o Derivatives Risk

      > Hedging Risk: When a derivative is used as a hedge against an opposite
        position that the fund also holds, any loss generated by the derivative
        should be substantially offset by gains on the hedged investment, and
        vice versa. While hedging can reduce or eliminate losses, it can also
        reduce or eliminate gains.

      > Correlation Risk: When the fund uses derivatives to hedge, it takes the
        risk that changes in the value of the derivative will not match those of
        the asset being hedged. Incomplete correlation can result in
        unanticipated losses.

      > Investment Risk: When the fund uses derivatives as an investment vehicle
        to gain market exposure, rather than for hedging purposes, any loss on
        the derivative investment will not be offset by gains on another hedged
        investment. The fund is therefore directly exposed to the risks of that
        derivative. Gains or losses from derivative investments may be
        substantially greater than the derivative's original cost.

      > Availability Risk: Derivatives may not be available to the fund upon
        acceptable terms. As a result, the fund may be unable to use derivatives
        for hedging or other purposes.

      > Credit Risk: When the fund uses derivatives, it is subject to the risk
        that the other party to the agreement will not be able to perform.

    o Active or Frequent Trading Risk: The fund may engage in active and
      frequent trading to achieve its 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.

    o Non-Diversified Status Risk: Because the fund may invest 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 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.

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.

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 $113.4 billion on behalf of
    approximately 4.6 million investor accounts as of July 31, 1999. As of
    such date, the MFS organization managed approximately $91.7 billion of net
    assets in equity funds and equity portfolios and approximately $21.6
    billion of assets invested in fixed income securities. Approximately $4.2
    billion of the assets managed by MFS are invested in securities of foreign
    issuers and foreign denominated securities of U.S. issuers. MFS is located
    at 500 Boylston Street, Boston, Massachusetts 02116.


      MFS provides investment management and related administrative services

- ------------------------------
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 $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 Fundamental 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 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

      > the plan has not redeemed its class B shares in the MFS Funds in order
        to purchase class A shares under this category.

    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, a market value of $500,000 or
        more invested in shares of any class or classes of the MFS Funds.

        THE RETIREMENT PLAN WILL QUALIFY UNDER THIS CATEGORY ONLY IF THE PLAN OR
        ITS SPONSORING ORGANIZATION INFORMS MFSC PRIOR TO THE PURCHASES THAT THE
        PLAN HAS 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 A PLAN QUALIFIES UNDER THIS CATEGORY; 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, 1997;

      > the plan's 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. MFS 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 Fundamental 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. This privilege applies to shares of the MFS
    money market funds only under certain circumstances.

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

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

    o Dividends 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. Dividends and
    capital gain distributions in amounts less than $10 will automatically be
    reinvested in additional shares of the fund. If you have elected to
    receive dividends and/or capital gain 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 dividends and other distributions
    reinvested in additional shares. Your request to change a distribution
    option must be received by MFSC by the record date for a dividend or
    distribution in order to be effective for that dividend or 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.

    FREE CHECKWRITING. You may redeem your class A or class C shares by
    writing checks against your account. Checks must be for at least $500 and
    investments made by check must have been in your account for at least 15
    days before you can write checks against them. There is no charge for this
    service. To authorize your account for checkwriting, contact MFSC (see
    back cover page for address and phone number).

      Shares in your account equal in value to the amount of the check plus
    the applicable CDSC (if any) and any income tax required to be withheld
    (if any) are redeemed to cover the amount of the check. If your account
    value is not great enough to cover these amounts, your check will be
    dishonored.

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). 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.

o   DISTRIBUTIONS

    Each fund intends to declare daily as dividends substantially all of its
    net income (excluding any realized net capital gains) and to pay these
    dividends to shareholders at least monthly. Any realized net capital gains
    are distributed 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 each 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 it has in the past and intends to do
    in the future), 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 of net capital gains or net short-term capital
    gains by the fund will reduce the 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.


    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 a 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 a 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

o   UNIQUE NATURE OF FUND

    MFS may serve as the investment adviser to other funds which have similar
    investment goals and principal investment policies and risks similar to a
    fund, and which may be managed by the 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   YEAR 2000 READINESS DISCLOSURE


    Each fund could be adversely affected if the computer systems used by MFS,
    the fund's other service providers or the companies in which the fund
    invests do not properly process date-related information from and after
    January 1, 2000. MFS recognizes the importance of the Year 2000 issue and,
    to address Year 2000 compliance, created a separately funded Year 2000
    Program Management Office in 1996 comprised of a specialized staff
    reporting directly to MFS senior management. The Office, with the help of
    external consultants, is responsible for overall coordination, strategy
    formulation, communications and issue resolution with respect to Year 2000
    issues. While MFS systems will be tested for Year 2000 readiness before
    the turn of the century, there are significant systems interdependencies
    in the domestic and foreign markets for securities, the business
    environments in which companies held by each fund operate and in MFS' own
    business environment. MFS has been working with each fund's other service
    providers to identify and respond to potential problems with respect to
    Year 2000 readiness and to develop contingency plans. Year 2000 readiness
    is also one of the factors considered by MFS in its ongoing assessment of
    companies in which each fund invests. There can be no assurance, however,
    that these steps will be sufficient to avoid any adverse impact on a fund.


o   PROVISION OF ANNUAL AND SEMIANNUAL REPORTS

    To avoid sending duplicate copies of materials to households, only one
    copy of a fund's annual and semiannual report 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 be sent personally
    to that shareholder.

IX FINANCIAL HIGHLIGHTS
- -----------------------


    The financial highlights table is intended to help you understand the
    fund's financial performance since the commencement of each fund's
    investment operations on January 4, 1999. Certain information reflects
    financial results for a single fund share. The total returns in the table
    represent the rate by which an investor would have earned (or lost) on an
    investment in the fund (assuming reinvestment of all distributions). This
    information has been audited by the fund's independent auditors, whose
    report, together with the fund's financial statements, are included in the
    fund's Annual Report to shareholders. The fund's Annual Report is
    available upon request by contacting MFSC (see back cover for address and
    telephone number). These financial statements are incorporated by
    reference into the SAI. The funds' independent auditors are Deloitte &
    Touche LLP.

             ----------                                         --------------

    2. MFS RESEARCH BOND FUND
       Foreign Securities
       (including Emerging Markets): .............................. 100%
       Lower Rated Bonds: ......................................... 100%
       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.

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

    The Trust, on behalf of each Fund, may not:

    (1) borrow amounts from banks in excess of 33 1/3% of its total assets
        including amounts borrowed;

    (2) underwrite securities issued by other persons except insofar as each
        Fund may technically be deemed an underwriter under the Securities Act
        of 1933, as amended (the "1933 Act"), 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 currencies
        and any type of option, Futures Contracts 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 currencies and any type of option,
        Futures Contracts and Forward Contracts) acquired as a result of the
        ownership of securities;


    (4) issue any senior securities except as permitted by the Investment
        Company Act of 1940, as amended (the "1940 Act"). For purposes of this
        restriction, collateral arrangements with respect to any type of swap,
        option, Forward Contracts and Futures Contracts 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
        commercial paper, the purchase of a portion or all of an issue of debt
        securities, the lending of portfolio securities, or the investment of
        the Fund's assets in repurchase agreements, shall not be considered the
        making of a loan; or

    (6) purchase any securities of an issuer of a particular industry, if as a
        result, 25% or more of its gross assets would be invested in securities
        of issuers whose principal business activities are in the same industry
        (except there is no limitation with respect to obligations issued or
        guaranteed by the U.S. Government or its agencies and instrumentalities
        and repurchase agreements collateralized by such obligations).

    In addition, each Fund has adopted the following nonfundamental policy
    which may be changed by the vote of the Trust's Board of Trustees without
    shareholder approval. The Trust, on behalf of any 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
        the Fund's 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 the 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.

VIII TAX CONSIDERATIONS
     For a discussion of tax considerations, see Part II of this SAI.

IX   INDEPENDENT AUDITORS AND FINANCIAL STATEMENTS

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.

      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,

      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; 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; 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.

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 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.

            be imposed) in the event that there is a change in law or
            regulations which results in a material adverse change to the tax
            advantaged nature of the plan, or in the event that the plan and/or
            sponsoring organization: (i) becomes insolvent or bankrupt; (ii) is
            terminated under ERISA or is liquidated or dissolved; or (iii) is
            acquired by, merged into, or consolidated with any other entity.

          > By a retirement plan whose sponsoring organization subscribes to the
            MFS Recordkeeper Plus product and which 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). A plan with a pre-existing account(s) with
            any MFS Fund which switches to the MFS Recordkeeper Plus product
            will not become eligible for this waiver category.

    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

      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).

    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. 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. 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.

    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.

    ABSENCE OF RATING: Where no rating has been assigned or where a rating has
    been suspended or withdrawn, it may be for reasons unrelated to the
    quality of the issue. Should no rating be assigned, the reason may be one
    of the following:

        1.  An application for rating was not received or accepted.

        2.  The issue or issuer belongs to a group of securities or companies
            that are not rated as a matter of policy.

        3.  There is a lack of essential data pertaining to the issue or
            issuer.

        4.  The issue was privately placed, in which case the rating is not
            published in Moody's publications.

    Suspension or withdrawal may occur if new and material circumstances
    arise, the effects of which preclude satisfactory analysis; if there is no
    longer available reasonable up-to-date data to permit a judgment to be
    formed; if a bond is called for redemption; or for other reasons.

                        STANDARD & POOR'S RATINGS SERVICES

    AAA: An obligation rated AAA has the highest rating assigned by S&P. 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: 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.

    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.

    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. Securities are not meeting current obligations and
    are extremely speculative. DDD designates the highest potential for
    recovery of amounts outstanding on any securities involved. For U.S.
    corporates, for example, DD indicates expected recovery of 50% -- 90% of
    such outstandings, 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.
