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

      1.    MFS Money Market Fund

o     Investment Objective

      The fund's investment objective is to seek as high a level of current
      income as is considered consistent with the preservation of capital and
      liquidity. The fund's objective may not be changed without shareholder
      approval.

o     Principal Investment Policies

      The fund is a money market fund, meaning it tries to maintain a share
      price of $1.00 while paying income to its shareholders. The fund invests
      in money market instruments, which are short-term notes or other debt
      securities issued by banks or other corporations, or the U.S. government
      or other governmental entities. Under normal market conditions, the fund
      invests at least 80% of its total assets in the following money market
      instruments:

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

      o     Repurchase agreements collateralized by U.S. government securities

      o     Certificates of deposit, bankers' acceptances and other bank
            obligations, provided that the bank obligations are insured by the
            Federal Deposit Insurance Corporation or the issuing bank has
            capital, surplus, and undivided profits in excess of $100 million

      o     Commercial paper which is rated within the highest credit rating by
            one or more rating agencies or which is unrated and considered by
            the fund's investment adviser, Massachusetts Financial Services
            Company (referred to as MFS or the adviser) to be of comparable
            quality

      o     Short-term corporate obligations which are rated within the two
            highest credit ratings by one or more rating agencies

      The fund may invest up to 20% of its total assets in short-term notes or
      other debt securities not specifically described in the list above that
      are of comparable high quality and liquidity. These securities may include
      U.S. dollar-denominated securities of foreign issuers, including foreign
      companies, foreign governments and sovereign entities (such as government
      agencies), foreign banks and U.S. branches of foreign banks. These
      securities will be rated in the two highest credit ratings by rating
      agencies or unrated and considered by MFS to be of comparable quality.


      The fund may invest in municipal securities and participation interests in
      municipal securities issued by banks when yield differentials make
      investment in these securities attractive. Up to 20% of the fund's assets
      may be invested in these securities. Municipal securities are bonds or
      other debt obligations of a U.S. state or political subdivision, such as a
      county, city, town,



                                       1
<PAGE>


      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.

      A money market fund must follow strict rules as to the investment quality,
      maturity, diversification and other features of the securities it
      purchases. Money market instruments purchased by the fund have maturities
      of 13 months or less, and the average remaining maturity of the securities
      cannot be greater than 90 days.

      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 type of
      securities and investment techniques and practices in which the fund may
      engage are identified in Appendix A to this Prospectus, and are discussed,
      together with their risks, in the fund's Statement of Additional
      Information.


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. 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     Money Market Instruments Risk: Money market instruments provide
            opportunities for income with low credit risk, but may result in a
            lower yield than would be available from debt obligations of a lower
            quality or longer term. Although the fund seeks to preserve the
            value of your investment at $1.00 per share, it is possible to lose
            money by investing in the fund.

      o     Foreign Markets Risk: Although the fund's investments in foreign
            issuers involve relatively low credit risk, an investment in the
            fund may involve a greater degree of risk than an investment in a
            fund that invests only in debt obligations of U.S. domestic issuers.
            Investing in foreign securities involves risks relating to
            political, social and economic developments abroad, as well as risks
            resulting from the differences between the regulations to which U.S.
            and foreign issuers and markets are subject:

            o     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.

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

            o     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.

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


                                       2

      o     Municipal Securities Risk:

            o     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.

            o     Maturity Risk: Interest rate risk will generally affect the
                  price of a municipal security more if the security has a
                  longer maturity. Municipal securities with longer maturities
                  will therefore be more volatile than other fixed income
                  securities with shorter maturities. Conversely, 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.

            o     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.

            o     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.


      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.

            with its custodian and dividend disbursing agent, and may enter into
            other such arrangements and directed brokerage arrangements (which
            would also have the effect of reducing the fund's expenses). Any
            such fee reductions are not reflected in the table. Had these fee
            reductions been taken into account, the "Total Annual Fund Operating

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

      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 funds' 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 objective. A 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 funds' 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 $137.95 billion as of November 30,
      2000.

      MFS provides investment management and related administrative services and
      facilities to the fund, including portfolio management and trade
      execution. For these services each fund pays MFS an annual management fee
      computed and paid monthly at an annual rate equal to 0.50% of the first
      $300 million of the average daily net assets of the fund; 0.45% of the
      next $400 million of such assets; 0.40% of the next $300 million of such
      assets; and 0.35% of such assets in excess of $1 billion. For each fund's
      fiscal year ended August 31, 2000, MFS received management fees of 0.42%
      and 0.50% of the average daily net assets of the MFS Money Market Fund and
      MFS Government Money Market Fund, respectively.


o     Portfolio Manager


      Jean O. Alessandro, an Assistant Vice President of MFS, has been employed
      in the investment management area of MFS since 1986 and has been a
      portfolio manager of each fund since January 1, 1998. Terri Vittozzi has
      been employed in the investment management area of MFS since 1992 and
      became a portfolio manager of each fund effective October 1, 2000.


o     Administrator

      MFS provides each fund with certain financial, legal, compliance,
      shareholder communications and other administrative services. MFS is
      reimbursed by each 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 funds.

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 funds,
      for which it receives compensation from the funds.

V     DESCRIPTION OF SHARE CLASS
--------------------------------------------------------------------------------

      Each fund offers one class of shares. Shares of each fund may be purchased
      and redeemed at net asset value, normally $1.00 per share.


                                       15
<PAGE>

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

      You may purchase, exchange and redeem 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
      shares, which are described in the next section under the caption
      "Investor Services and Programs."

o     How to Purchase Shares

      You may purchase shares of each fund at net asset value without incurring
      a sales charge. It is anticipated that the net asset value of $1.00 per
      share will remain constant. While there is no sales charge, your financial
      adviser may charge you for their services in connection with purchasing
      shares of either fund.

      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:


            o     a tax-deferred retirement program (other than an IRA) where
                  investments are made by means of group remittal statements; or

            o     an employer sponsored investment program.


      The minimum initial investment for IRAs is $250 per account.

      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 of either fund for shares of the other fund
      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). If you exchange your shares out of the funds into class A shares of
      any other


                                       16
<PAGE>

      MFS fund, you will pay the initial sales charge if you have not already
      paid this charge on these shares.

      However, you will not pay the charge if:

      o     the shares exchanged from either fund were acquired by an exchange
            from any other MFS fund;

      o     the shares exchanged from either fund were acquired by automatic
            investment of dividends from any other MFS fund paid after June 1,
            1992; or

      o     the shares being exchanged would have, at the time of purchase, been
            eligible for purchase at net asset value had you invested directly
            in the MFS fund into which the exchange is being made.


      In addition, shares of the MFS Money Market fund previously acquired
      through an exchange from class C or class I shares of an MFS Fund may be
      exchanged for class C shares or class I shares of any of the other MFS
      Funds at net asset value. Shares otherwise subject to a contingent
      deferred sales charge ("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.


      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 market timing 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. A fund will send 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).


                                       17
<PAGE>

      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,
      a fund may suspend redemptions or postpone payment. If you purchased the
      shares you are redeeming by check, a 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


                                       18
<PAGE>

      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.

      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. Neither fund expects 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 either fund, you have available to you a number of
      services and investment programs. Some of these services and programs may
      not be available to you if your shares are held in the name of your
      financial adviser or if your investment in a fund is made through a
      retirement plan.

o     Distribution Options

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


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

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

      o     Dividend and capital gain distributions in cash.

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


o     Purchase and Redemption Programs

      For your convenience, the following purchase and redemption programs are
      made available to you by the MFS family of funds (the MFS funds) 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, into class A shares of any other MFS


                                       20
<PAGE>

      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.

      Systematic Withdrawal Plan. You may elect to automatically receive (or
      designate someone else to receive) periodic payments of at least $100.
      Each payment under this systematic withdrawal is funded through the
      redemption of your fund shares.

      Free Checkwriting. You may redeem your shares of certain funds 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 fund's shares is based on its net asset value. The net
      asset value of each fund's shares is determined at the close of regular
      trading each day that the New York Stock Exchange is open for trading
      (generally, 4:00 p.m., Eastern time) (referred to as the valuation time).
      The New York Stock Exchange is closed on most national holidays and Good
      Friday. To determine net asset value, the funds value their securities at
      amortized cost or at fair value as determined by the adviser under the
      direction of the Board of Trustees that oversees the fund if the Trustees
      determine that amortized cost does not constitute fair value.

      Fair value pricing may be used by a fund when current market values are
      unavailable or when an event occurs after the close of the market 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 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

      Each fund intends to declare daily as dividends substantially all of its
      net income (excluding any net capital gains) and to pay these dividends to
      shareholders at least monthly. Because the net income of each fund's
      shares is declared as a dividend each day that the net income of a share
      is determined, the net asset value of a fund's shares remains at $1.00 per
      share immediately after such determination and dividend declaration. Any
      increase in the value of your investment in the funds, representing the
      reinvestment of dividend income, is reflected by an increase in the number
      of shares of a fund in your account. 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 a fund may have on
      your particular tax situation.


                                       22
<PAGE>


      Taxability of Distributions. As long as a fund qualifies for treatment as
      a regulated investment company (which each fund 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 (including distributions derived from interest
      or municipal securities) are generally taxable as ordinary income.
      Distributions derived from interest on U.S. government securities (but not
      distributions of gain from the sale of such securities) may be exempt from
      state and local taxes. 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.


      If you are neither a citizen nor a resident of the U.S., each fund will in
      which you invest 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. Each fund is also required in certain circumstances to apply
      backup withholding at the rate of 31% on taxable dividends 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 in a should read
      that fund's Account Application for additional information regarding
      backup withholding of federal income tax.


o     Unique Nature of Fund

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


o     Provision of Annual and Semiannual Reports and Prospectuses

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

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

      The financial highlights table is intended to help you understand each
      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 a fund (assuming reinvestment of all
      distributions). This information has been audited by the funds'
      independent auditors, whose report, together with a fund's financial
      statements, are included in each fund's Annual Report to shareholders.
      Each 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.

I     DEFINITIONS

      "Funds" -- MFS(R) Money Market Fund and MFS(R) Government Money Market
      Fund, each a series of the Trust.

      "Trust" -- MFS Series Trust IV, a Massachusetts business trust. The Trust
      was known as Massachusetts Cash Management Trust prior to August 27, 1993.

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


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

      "Prospectus" -- The Prospectus of the Funds, dated January 1, 2001, as
      amended or supplemented from time to time.


II    MANAGEMENT OF THE FUNDS

      The Funds


      Each Fund is a diversified series of the Trust. This means that, with
      respect to 75% of a Fund's total assets, the Fund may not (1) purchase
      more than 10% of the outstanding voting securities of any one issuer, or
      (2) purchase securities of any issuer if as a result more than 5% of a
      Fund's total assets would be invested in that issuer's securities. This
      limitation does not apply to obligations of the U.S. Government or its
      agencies or instrumentalities. The Trust is an open-end management
      investment company.

      Each Fund and its Adviser and Distributor have adopted a code of ethics as
      required under the Investment Company Act of 1940 (the "1940 Act").
      Subject to certain conditions and restrictions, this code permits
      personnel subject to the code to invest in securities for their own
      accounts, including securities that may be purchased, held or sold by the
      Funds. Securities transactions by some of these persons may be subject to
      prior approval of the Adviser's Compliance Department. Securities
      transactions of certain personnel are subject to quarterly reporting and
      review requirements. The code is on public file with, and is available
      from, the SEC. See the back cover of the prospectus for information on
      obtaining a copy.


      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 a 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.

III   SALES CHARGES AND DISTRIBUTION PLAN PAYMENTS

      Sales Charges

      Sales charges, if any, paid in connection with the purchase and sale of
      each Fund's 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 each Fund under its Distribution Plan, if any, 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 each Fund for certain specified periods, and
      information concerning purchases by each 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 a Fund. The Trustees (together with the Trustees of certain
      other MFS funds) have directed the Adviser to allocate a total of $43,800
      of commission business from certain MFS funds (including the Funds) to the
      Pershing Division of Donaldson Lufkin & Jenrette as consideration for the
      annual renewal of certain publications provided by Lipper Inc. (which
      provides information useful to the Trustees in reviewing the relationship
      between the funds and the Adviser).


V     SHARE OWNERSHIP

      Information concerning the ownership of each Fund's shares by Trustees and
      officers of the Trust as a group, by investors who control a Fund, if any,
      and by investors who own 5% or more of any class of Fund shares, if any,
      is set forth in Appendix F to this Part I.

VI    PERFORMANCE INFORMATION

      Performance information, as quoted by the Funds in sales literature and
      marketing materials, is set forth in Appendix G to this Part I.

VII   INVESTMENT TECHNIQUES, PRACTICES, RISKS AND RESTRICTIONS

      Investment Techniques, Practices and Risks

      The investment objective and principal investment policies of each Fund
      are described in the Prospectus. In pursuing its investment objective and
      principal investment policies, each


                                   Part I -- 1
<PAGE>

      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 the investment techniques
      and practices of the MFS Money Market Fund:

                                                           Percentage Limitation
      Investment Limitation                                (based on net assets)
      Finance companies, banks, bank
         holding companies and utility                           Up to 75%
         companies ........................................... of net assets
      Bank obligations where the issuing
         bank has capital, surplus and
         undivided profits less than or equal                    Up to 10%
         to $100 million ..................................... of net assets

      Investment Restrictions

      The Funds have 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 Series or class, as applicable, or
      (ii) 67% or more of the outstanding shares of the Trust or the Fund 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 with respect to
      the Funds' policy on borrowing and investing in illiquid securities, 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 policy.

      Neither Fund may:

      (1)   Borrow money or pledge, mortgage or hypothecate its assets, except
            as a temporary measure in an amount not to exceed one-third of its
            total assets (taken at current value) to facilitate redemptions (a
            loan limitation in excess of 5% is generally associated with a
            leveraged fund, but, since neither Fund anticipates paying interest
            on borrowed money at rates comparable to its yield, neither Fund has
            any intention of attempting to increase its net income by means of
            borrowing. Each Fund will borrow money only to accommodate requests
            for the repurchase of its shares while effecting an orderly
            liquidation of portfolio securities); and except that either Fund
            may enter into repurchase agreements (see description above);

      (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)   Purchase voting securities of any issuer or purchase the securities
            of any issuer if, as a result thereof, more than 25% of that Fund's
            total assets (taken at current value) would be concentrated in any
            one industry; provided, however, that (a) there is no limitation in
            respect to investments in obligations issued or guaranteed by the
            U.S. Government or its agencies or instrumentalities, and (b) each
            Fund may invest up to 75% of its assets in all finance companies as
            a group, all banks and bank holding companies as a group and all
            utility companies as a group when in the opinion of management yield
            differentials and money market conditions suggest and when cash is
            available for such investment and instruments are available for
            purchase which fulfill the Fund's objective in terms of quality and
            marketability.

      (4)   Purchase or retain real estate (including limited partnership
            interests but excluding securities of companies which deal in real
            estate or interests therein), mineral leases, commodities or
            commodity contracts;

      (5)   Make loans to other persons except by the purchase of obligations in
            which that Fund is authorized to invest and by entering into
            repurchase agreements (see description above); not more than 10% of
            the total assets of either Fund (taken at current value) will be
            subject to repurchase agreements maturing in more than seven days;

      (6)   Purchase the securities of any issuer if such purchase, at the time
            thereof, would cause more than 5% of that Fund's total assets (taken
            at current value) to be invested in the securities of such issuer,
            other than securities issued or guaranteed by the U.S. Government or
            its agencies or instrumentalities;

      (7)   Purchase securities of any issuer (other than securities issued or
            guaranteed by the U.S. Government or its agencies or
            instrumentalities) if such purchase, at the time thereof would cause
            that Fund to hold more than 10% of any class of securities of such
            issuer; for this purpose all debt obligations of an issuer maturing
            in less than one year shall be deemed a single class.

      (8)   Invest in companies for the purpose of exercising control or

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 -- Each Trust (except MFS Series Trust XI) 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 of up to 0.0175% on the first $2.0 billion;
     0.0130% on the next $2.5 billion; 0.0005% on the next $2.5 billion; and
     0.0% on amounts in excess of $7.0 billion, 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.

     CODE OF ETHICS
     The Fund and its Adviser and Distributor have adopted a code of ethics as
     required under the Investment Company Act of 1940 ("the 1940 Act"). Subject
     to certain conditions and restrictions, this code permits personnel subject
     to the code to invest in securities for their own accounts, including
     securities that may be purchased, held or sold by the Fund. Securities
     transactions by some of these persons may be subject to prior approval of
     the Adviser's Compliance Department. Securities transactions of certain
     personnel are subject to quarterly reporting and review requirements. The
     code is on public file with, and is available from, the SEC. See the back
     cover of the prospectus for information on obtaining a copy.

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.

       In the case of a retirement plan (or multiple plans maintained by the
     same plan sponsor) which has established accounts with MFSC, on or after
     April 1, 2000 and is, at that time, a party to a retirement plan
     recordkeeping or administrative services agreement with MFD or one of its
     affiliates pursuant to which such services are provided with respect to at
     least $10 million in plan assets, MFD may retain the service fee paid by
     the fund with respect to shares purchased by such plan for the first year
     after purchase. Dealers will become eligible to receive the ongoing
     applicable service fee with respect to such shares commencing in the 13th
     month following purchase.

       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.

       The Fund has entered into an arrangement with State Street Brokerage
     Services, Inc. ("SSB"), an affiliate of the Custodian, under which, with
     respect to any brokerage transactions directed to SSB, the Fund receives,
     on a trade-by-trade basis, a credit for part of the brokerage commission
     paid, which is applied against other expenses of the Fund, including the
     Fund's custodian fee. The Adviser receives no direct or indirect benefit
     from this arrangement.

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

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

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

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

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

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

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

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

IX   PERFORMANCE INFORMATION

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

X    SHAREHOLDER SERVICES

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

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

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

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

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

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

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

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

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

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

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

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

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

     REINSTATEMENT PRIVILEGE -- Shareholders of the Fund and shareholders of the
     other MFS Funds (except MFS Money Market Fund, MFS Government Money Market
     Fund and holders of Class A shares of MFS Cash Reserve Fund in the case
     where shares of such funds are acquired through direct purchase or
     reinvested dividends) who have redeemed their shares have a one-time right
     to reinvest the redemption proceeds in any of the MFS Funds (if shares of
     the fund are available for sale) at net asset value (without a sales
     charge). For shareholders who exercise this privilege after redeeming class
     A or class C shares, if the redemption involved a CDSC, your account will
     be credited with the appropriate amount of the CDSC you paid; however, your
     new class A or class C shares (as applicable) will still be subject to a
     CDSC for up to one year from the date you originally purchased the shares
     redeemed.

       Until December 31, 2001, shareholders who redeem class B shares and then
     exercise their 90-day reinstatement privilege may reinvest their redemption
     proceeds either in

       o class B shares, in which case any applicable CDSC you paid on the
         redemption will be credited to your account, and your new shares will
         be subject to a CDSC which will be determined from the date you
         originally purchased the shares redeemed, or

       o class A shares, in which case the class A shares purchased will not be
         subject to a CDSC, but if you paid a CDSC when you redeemed your class
         B shares, your account will not be credited with the CDSC you paid.

       After December 31, 2001, shareholders who exercise their 90-day
     reinstatement privilege after redeeming class B shares may reinvest their
     redemption proceeds only in class A shares as described as the second
     option above.

       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.
     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.

          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.

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

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

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

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

    COMMISSION
    PAID BY MFD
    TO DEALERS               CUMULATIVE PURCHASE AMOUNT
    ------------------------------------------------------
    1.00%                    On the first $2,000,000, plus
    0.80%                    Over $2,000,000 to $3,000,000, plus
    0.50%                    Over $3,000,000 to $50,000,000, plus
    0.25%                    Over $50,000,000

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

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

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

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

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

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

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

      For most of the MFS Funds:

      o In lieu of the sales commission and service fees normally paid by MFD to
        broker-dealers of record as described in the Prospectus, MFD has agreed
        to pay Bear, Stearns & Co. Inc. the following amounts with respect to
        Class A shares of the Fund purchased through a special retirement plan
        program offered by a third party administrator: (i) an amount equal to
        0.05% per annum of the average daily net assets invested in shares of
        the Fund pursuant to such program, and (ii) an amount equal to 0.20% of
        the net asset value of all net purchases of shares of the Fund made
        through such program, subject to a refund in the event that such shares
        are redeemed within 36 months.

      o Until terminated by MFD, MFD will incur, on behalf of H. D. Vest
        Investment Securities, Inc., the initial ticket charge of $15 with
        respect to purchases of shares of any MFS fund made through VESTADVISOR
        accounts. MFD will not incur such charge with respect to redemptions or
        repurchases of fund shares, exchanges of fund shares, or shares
        purchased or redeemed through systematic investment or withdrawal plans.

      o The following provisions shall apply to any retirement plan (each a
        "Merrill Lynch Daily K Plan") whose records are maintained on a daily
        valuation basis by either Merrill Lynch, Pierce, Fenner & Smith
        Incorporated ("Merrill Lynch"), or by an independent recordkeeper (an
        "Independent Recordkeeper") whose services are provided through a
        contract or alliance arrangement with Merrill Lynch, and with respect to
        which the sponsor of such plan has entered into a recordkeeping service
        agreement with Merrill Lynch (a "Merrill Lynch Recordkeeping
        Agreement").

        The initial sales charge imposed on purchases of Class A shares of the
        Funds, and the contingent deferred sales charge ("CDSC") imposed on
        certain redemptions of Class A shares of the Funds, is waived in the
        following circumstances with respect to a Merrill Lynch Daily K Plan:

        (i) if, on the date the Plan sponsor signs the Merrill Lynch
            Recordkeeping Agreement, such Plan has $3 million or more in
            assets invested in broker-dealer sold funds not advised or managed
            by Merrill Lynch Asset Management L.P. ("MLAM") that are made
            available pursuant to agreements between Merrill Lynch and such
            funds' principal underwriters or distributors, and in funds
            advised or managed by MLAM (collectively, the "Applicable
            Investments"); or

       (ii) if such Plan's records are maintained by an Independent
            Recordkeeper and, on the date the Plan sponsor signs the Merrill
            Lynch Recordkeeping Agreement, such Plan has $3 million or more in
            assets, excluding money market funds, invested in Applicable
            Investments; or

      (iii) such Plan has 500 or more eligible employees, as determined by the
            Merrill Lynch plan conversion manager on the date the Plan sponsor
            signs the Merrill Lynch Recordkeeping Agreement.

      The CDSC imposed on redemptions of Class B shares of the Fund is waived
      in the following circumstances with respect to a Merrill Lynch Daily K
      Plan:

        (i) if, on the date the Plan sponsor signs the Merrill Lynch
            Recordkeeping Agreement, such Plan has less than $3 million in
            assets invested in Applicable Investments;

       (ii) if such Plan's records are maintained by an independent
            recordkeeper and, on the date the Plan sponsor signs the Merrill
            Lynch Recordkeeping Agreement, such Plan has less than $3 million
            dollars in assets, excluding money market funds, invested in
            Applicable Investments; or

      (iii) such Plan has fewer than 500 eligible employees, as determined by
            the Merrill Lynch plan conversion manager on the date the Plan
            sponsor signs the Merrill Lynch Recordkeeping Agreement.

      No front-end commissions are paid with respect to any Class A or Class B
      shares of the Fund purchased by any Merrill Lynch Daily K Plan.

      o In lieu of the sales commission and service fees normally paid by MFD to
        borker-dealers of record as described in the Prospectus, MFD has agreed
        to pay Bear, Stearns & Co. Inc. the following amounts with respect to
        Class A shares of the Fund purchased through a special retirement plan
        program offered by a third party administrator: (i) an amount equal to
        0.05% per annum of the average daily net assets invested in shares of
        the Fund pursuant to such program, and (ii) an amount equal to 0.20% of
        the net asset value of all net purchases of shares of the Fund made
        through such program, subject to a refund in the event that such shares
        are redeemed within 36 months.

      For MFS Union Standard(R) Equity Fund:

      o The initial sales charge on Class A shares will be waived on shares
        purchased using redemption proceeds from a separate institutional
        account of Connecticut General Life Insurance Company with respect to
        which MFS Institutional Advisors, Inc. acts as investment adviser. No
        commissions will be payable to any dealer, bank or other financial
        intermediary with respect to shares purchased in this manner.

      For MFS Emerging Growth Fund, MFS Research Fund, MFS Capital
      Opportunities Fund and MFS Money Market Fund:

      o Class A shares of the Fund may be purchased at net asset value by one or
        more Chilean retirement plans, known as Administradores de Fondos de
        Pensiones, which are clients of the 1850 K Street N.W., Washington D.C.
        office of Dean Witter Reynolds, Inc. ("Dean Witter").

        MFD will waive any applicable contingent deferred sales charges upon
        redemption by such retirement plans on purchases of Class A shares over
        $1 million, provided that (i) in lieu of the commissions otherwise
        payable as specified in the prospectus, MFD will pay Dean Witter a
        commission on such purchases equal to 1.00% (including amounts in excess
        of $5 million) and (ii) if one or more such clients redeem all or a
        portion of these shares within three years after the purchase thereof,
        Dean Witter will reimburse MFD for the commission paid with respect to
        such shares on a pro rata basis based on the remaining portion of such
        three-year period.

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

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

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

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

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

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

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

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

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

    o   Sovereign Debt -- Investment in sovereign debt can involve a high degree
        of risk. The governmental entity that controls the repayment of
        sovereign debt may not be able or willing to repay the principal and/or
        interest when due in accordance with the terms of such debt. A
        governmental entity's willingness or ability to repay principal and
        interest due in a timely manner may be affected by, among other factors,
        its cash flow situation, the extent of its foreign reserves, the
        availability of sufficient foreign exchange on the date a payment is
        due, the relative size of the debt service burden to the economy as a
        whole, the governmental entity's policy towards the International
        Monetary Fund and the political constraints to which a governmental
        entity may be subject. Governmental entities may also be dependent on
        expected disbursements from foreign governments, multilateral agencies
        and others abroad to reduce principal and interest on their debt. The
        commitment on the part of these governments, agencies and others to make
        such disbursements may be conditioned on a governmental entity's
        implementation of economic reforms and/or economic performance and the
        timely service of such debtor's obligations. Failure to implement such
        reforms, achieve such levels of economic performance or repay principal
        or interest when due may result in the cancellation of such third
        parties' commitments to lend funds to the governmental entity, which may
        further impair such debtor's ability or willingness to service its debts
        in a timely manner. Consequently, governmental entities may default on
        their sovereign debt. Holders of sovereign debt (including the Fund) may
        be requested to participate in the rescheduling of such debt and to
        extend further loans to governmental entities. There is no bankruptcy
        proceedings by which sovereign debt on which governmental entities have
        defaulted may be collected in whole or in part.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

      A call option written by the Fund is "covered" if the Fund owns the
    security underlying the call or has an absolute and immediate right to
    acquire that security without additional cash consideration (or for
    additional cash consideration if the Fund owns liquid and unencumbered
    assets equal to the amount of cash consideration) upon conversion or
    exchange of other securities held in its portfolio. A call option is also
    covered if the Fund holds a call on the same security and in the same
    principal amount as the call written where the exercise price of the call
    held (a) is equal to or less than the exercise price of the call written or
    (b) is greater than the exercise price of the call written if the Fund owns
    liquid and unencumbered assets equal to the difference. A put option written
    by the Fund is "covered" if the Fund owns liquid and unencumbered assets
    with a value equal to the exercise price, or else holds a put on the same
    security and in the same principal amount as the put written where the
    exercise price of the put held is equal to or greater than the exercise
    price of the put written or where the exercise price of the put held is less
    than the exercise price of the put written if the Fund owns liquid and
    unencumbered assets equal to the difference. Put and call options written by
    the Fund may also be covered in such other manner as may be in accordance
    with the requirements of the exchange on which, or the counterparty with
    which, the option is traded, and applicable laws and regulations. If the
    writer's obligation is not so covered, it is subject to the risk of the full
    change in value of the underlying security from the time the option is
    written until exercise.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

  PART II - APPENDIX D

                           DESCRIPTION OF BOND RATINGS

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

                         MOODY'S INVESTORS SERVICE, INC.

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

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

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

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

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

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

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

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

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

                       STANDARD & POOR'S RATINGS SERVICES

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

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

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

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

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

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

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

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

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

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

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

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

    r: This symbol is attached to the ratings of instruments with significant
    noncredit risks. It highlights risks to principal or volatility of expected
    returns which are not addressed in the credit rating. Examples include:
    obligations linked or indexed to equities, currencies, or commodities;
    obligations exposed to severe prepayment risk -- such as interest-only or
    principal-only mortgage securities; and obligations with unusually risky
    interest terms, such as inverse floaters.

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

                            FITCH IBCA, DUFF & PHELPS

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

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

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

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

    Speculative Grade

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

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

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

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

    NOTES

    "+" or "-" may be appended to a rating to denote relative status within
    major rating categories. Such suffixes are not added to the "AAA" long-term
    rating category, or to categorize below "CCC".

    "NR" indicates that Fitch does not rate the issuer or issue in question.

    "WITHDRAWN": A rating is withdrawn when Fitch deems the amount of
    information available to be inadequate for rating purposes, or when an
    obligation matures, is called, or refinanced.

o     Investment Objective


      The fund's investment objective is to provide as high a level of current
      income exempt from federal income tax as is considered consistent with
      prudent investing while seeking protection of shareholders' capital. The
      fund's objective may be modified 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 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 income
      tax. However, the interest income on certain of these municipal securities
      may be subject to an alternative minimum tax.


      While the fund focuses on municipal securities rated, or issued by issuers
      who have securities that are rated, in one of the top three credit rating
      by credit rating agencies, the fund may also invest in speculative
      securities. These are securities rated in the lowest investment grade
      category 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.

      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 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:

            o     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.

            o     Maturity Risk: Interest rate risk will generally affect the
                  price of a municipal security more if the security has a
                  longer maturity. Municipal securities with longer maturities
                  will therefore be more volatile than other fixed income
                  securities with shorter maturities. Conversely, 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.

            o     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.

            o     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: 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


                                       2

            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. 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.

      *     The Lehman Brother Muni Bond Index is an unmanaged index comprised
            of approximately 50,000 actual bonds (with no floating or zero
            coupons) which are investment grade, fixed-rate, long-term
            maturities (greater than two years). It is not possible to invest
            directly in an index.
      ##    The Lipper Mutual Fund Indices are unmanaged,
            net-asset-value-weighted indices of the largest qualifying mutual
            funds within their respective investment objectives, adjusted for
            the reinvestment of capital gains distributions and income
            dividends. It is not possible to invest directly in an index.

      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%.

      The fund commenced investment operations on December 16, 1976 with the
      offering of class A shares and subsequently offered class B shares on
      September 7, 1993. 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 shares been offered for the entire period. If you would

o     Expense Table

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

      Total Annual Fund Operating Expenses(3) ...........      0.58%          1.36%
</TABLE>

      ----------
      (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 either 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 its class B shares and the services provided to you
            by your financial adviser (referred to as distribution and service
            fees). The class B service fee is not currently in effect, and may
            equal up to 0.25% annually upon implementation by the board of
            trustees which oversee the fund.
      (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. Had
            these fee reductions been taken into account, "Total Annual Fund
            Operating Expenses" would be lower, and would equal 0.56% for class
            A shares and 1.34% for class B shares.

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:

</TABLE>


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

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

o     Further Information on Investment Strategies and Risks

      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 $137.95 billion as of November 30,
      2000.


      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 on the basis of a formula based upon a
      percentage of the fund's average daily net assets plus a percentage of its
      gross income (i.e., income other than gains from the sale of securities)
      in each case on an annualized basis for the fund's then-current fiscal
      year. The applicable percentages are reduced as assets and income reach
      the following levels:

         Annual Rate of Management Fee         Annual Rate of Management Fee
       Based on Average Daily Net Assets           Based on Gross Income
      ----------------------------------     ----------------------------------
      .220% of the first $200 million        4.12% of the first $16 million
      .187% of average daily net assets in   3.51% of gross income in excess of
         excess of $200 million                 $16 million
      .168% of average daily net assets in   3.16% of gross income in excess of
         excess of $2 billion                   $160 million


      For the fiscal year ended August 31, 2000, the fund paid MFS an aggregate
      management fee equal to 0.40% of the average daily net assets of the fund.


o     Portfolio Manager


      Geoffrey L. Schechter and Michael L. Dawson are the portfolio managers for
      the fund. Mr. Schechter, a Vice President of MFS, has been a portfolio
      manager of the fund since March, 1998 and has been employed in the
      investment management area of MFS since June, 1993. Mr. Dawson, a Vice
      President of MFS, became a portfolio manager of the fund on March 23, 2000
      and has been employed in the investment management area of MFS since
      September, 1998. Mr. Dawson was employed as a sales representative in the
      Institutional Sales Group at Fidelity Capital Markets from March, 1997 to
      May, 1998. From January, 1993 to March, 1997, Goldman Sachs & Co. employed
      Mr. Dawson in the Institutional Sales -- Fixed Income Divisions.


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 and B 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 or B 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:
                                                -------------------------------
                                                    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          1.70
      $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.


                                       11
<PAGE>

      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

            o     the plan had established an account with MFSC; and

            o     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 (referred to as 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


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

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

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


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

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


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

                  The retirement plans will qualify under this category only if
                  the plans or their sponsoring organization inform MFSC prior
                  to the purchases that the plans have a market value of
                  $500,000 or more invested in shares of any class or classes of
                  the MFS funds; MFSC has no obligation independently to
                  determine whether such plans qualify under this category; and



                                       12
<PAGE>

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


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

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


            o     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

      Third                                                       3%
      Fourth                                                      3%
      Fifth                                                       2%

      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     Calculation of CDSC

      As discussed above, certain investments in class A and B 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 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.


                                       13


<PAGE>

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 B shares and the
services provided to you by your financial adviser. These annual distribution
and service fees for class B shares may equal up to 1.00% (a 0.75% distribution
fee and a 0.25% service fee), and are paid out of the assets of class B shares.
Over time, these fees will increase the cost of your shares and may cost you
more than paying other types of sales charges. 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, payment of the class B service fee is currently not being
imposed and will be paid by the fund on such date as the Trustees of the fund
determine.

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

You may purchase, exchange and redeem class A and B 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:


            a tax-deferred retirement program (other than an IRA) where
            investments are made by means of group remittal statements; or

            an employer sponsored investment program.


The minimum initial investment for IRAs is $250 per account.

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.


                                       15
<PAGE>

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 for this service.


                                       16
<PAGE>

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).


For shareholders who exercise this privilege after redeeming class A shares, if
the redemption involved a CDSC, your account will be credited with the
appropriate amount of the CDSC you paid; however, your new class A shares will
still be subject to a CDSC for up to one year from the date you originally
purchased the shares redeemed.

Until December 31, 2001, shareholders who redeem class B shares and then
exercise their 90-day reinstatement privilege may reinvest their redemption
proceeds either in

o     class B shares, in which case any applicable CDSC you paid on the
      redemption will be credited to your account, and your new shares will be
      subject to a CDSC which will be determined from the date you originally
      purchased the shares redeemed, or



                                       17
<PAGE>


o     class A shares, in which case the class A shares purchased will not be
      subject to an initial sales charge or a CDSC, but if you paid a CDSC when
      you redeemed your class B shares, your account will not be credited with
      the CDSC you paid.

After December 31, 2001, shareholders who exercise their 90-day reinstatement
privilege after redeeming class B shares may reinvest their redemption proceeds
only in class A shares as described as the second option above.


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.


                                       18

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

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

o     Dividend and capital gain distributions in cash.

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


o Purchase and Redemption Programs

For your convenience, the following purchase and redemption programs are made
available to you with respect to class A and B 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


                                       19
<PAGE>

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 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 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 B 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). The
New York Stock Exchange is closed on most national holidays and Good Friday. 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


                                       21
<PAGE>

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 will
reduce the fund's net asset value per share. Therefore, if you buy shares
shortly before the record date of such 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 investment
goals and principal investment policies and risks similar to those of 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.


                                       22
<PAGE>


o Provision of Annual and Semiannual Reports and Prospectuses

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

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

The financial highlights table is intended to help you understand the fund's
financial performance since 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

      "Fund" -- MFS Municipal Bond Fund, a diversified series of the Trust.

      "Trust" -- MFS Series Trust IV, a Massachusetts business Trust, organized
      on September 8, 1975. The Trust was known as "Massachusetts Cash
      Management Trust" prior to August 27, 1993.

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


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

      "Prospectus" -- The Prospectus of the Fund, dated January 1, 2001, as
      amended or supplemented from time to time.


II    MANAGEMENT OF THE FUND

      The Fund


      The Fund is a diversified series of the Trust. This means that, with
      respect to 75% of its total assets, the Fund may not (1) purchase more
      than 10% of the outstanding voting securities of any one issuer, or (2)
      purchase securities of any issuer if as a result more than 5% of the
      Fund's total assets would be invested in that issuer's securities. This
      limitation does not apply to obligations of the U.S. Government or its
      agencies or instrumentalities. The Trust is an open-end management
      investment company.

      Each Fund and its Adviser have adopted a code of ethics as required under
      the Investment Company Act of 1940 (the "1940 Act"). Subject to certain
      conditions and restrictions, this code permits personnel subject to the
      code to invest in securities for their own accounts, including securities
      that may be purchased, held or sold by the Funds. Securities transactions
      by some of these persons may be subject to prior approval of the Adviser's
      or the Distributor's Compliance Department. Securities transactions of
      certain personnel are subject to quarterly reporting and review
      requirements. The code is on public file with, and is available from, the
      SEC. See the back cover of the prospectus for information on obtaining a
      copy.


      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.

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 $43,800
      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 Inc. (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
      any, and by investors who own 5% or more of any class of Fund shares, if
      any, is set forth in Appendix F to this Part I.

VI    PERFORMANCE INFORMATION

      Performance information, as quoted by the Fund in sales literature and
      marketing materials, is set forth in Appendix G to this Part I.

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


                                  Part I -- 1
<PAGE>

      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     Speculative Securities may not exceed 40% of net assets.

      o     Unrated Securities may not exceed 10% of 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 the Fund or class, as applicable, or
      (ii) 67% or more of the outstanding shares of the Trust or the Fund or
      class, as applicable, present at a meeting at which holders of more than
      50% of the outstanding shares of the Trust or the Fund or class, as
      applicable, are represented in person or by proxy). Except with respect to
      the Fund's policy on borrowing and investing in illiquid securities, 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 policy. In the event of
      a violation of non-fundamental policy (1), the Fund will reduce the
      percentage of its assets invested in illiquid investments in due course,
      taking into account the best interest of shareholders.

      The Fund may not:

      (1)   borrow money, except as a temporary measure for extraordinary or
            emergency purposes, and then only in an amount not exceeding 10% of
            its gross assets, or pledge, mortgage or hypothecate an amount of
            its assets taken at market value which would exceed 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 and Options on Futures Contracts 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)   Purchase or sell real estate (including limited partnership
            interests but excluding Municipal Bonds secured by real estate or
            interests therein), interests in oil, gas or mineral leases,
            commodities or commodity contracts (except Futures Contracts and
            Options on Futures Contracts) in the ordinary course of its
            business;

      (4)   Make loans to other persons except through the use of repurchase
            agreements or the purchase of commercial paper. Not more than 10% of
            its total assets will be invested in repurchase agreements maturing
            in more than seven days. For these purposes the purchase of a
            portion of an issue of debt securities which is part of an issue to
            the public shall not be considered the making of a loan;

      (5)   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 securities issued or guaranteed by the U.S. Government or its
            agencies or instrumentalities, or invest more than 25% of its total
            assets taken at market value in securities of issuers in any one
            industry;

      (6)   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 a member,
            partner, 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, all taken at market value, 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, all taken at market value;

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

      (8)   sell any security which the Fund does not own unless by virtue of
            its ownership of other securities it 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 writing, purchasing and
            selling of puts, calls or combinations thereof with respect to
            securities and Futures Contracts.

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


                                  Part I -- 2
<PAGE>

            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
            determined to be liquid by the Trust's Board of Trustees (or its
            delegee), will not be subject to this 15% limitation;


      (2)   invest 25% or more of the market value of its total assets in
            securities of issuers in any one industry.

</TABLE>

The Fund commenced investment operations on December 16, 1976, with the offering
of class A shares, and subsequently offered class B shares on September 7, 1993.
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 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 -- Each Trust (except MFS Series Trust XI) 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 of up to 0.0175% on the first $2.0 billion;
     0.0130% on the next $2.5 billion; 0.0005% on the next $2.5 billion; and
     0.0% on amounts in excess of $7.0 billion, 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.

     CODE OF ETHICS
     The Fund and its Adviser and Distributor have adopted a code of ethics as
     required under the Investment Company Act of 1940 ("the 1940 Act"). Subject
     to certain conditions and restrictions, this code permits personnel subject
     to the code to invest in securities for their own accounts, including
     securities that may be purchased, held or sold by the Fund. Securities
     transactions by some of these persons may be subject to prior approval of
     the Adviser's Compliance Department. Securities transactions of certain
     personnel are subject to quarterly reporting and review requirements. The
     code is on public file with, and is available from, the SEC. See the back
     cover of the prospectus for information on obtaining a copy.

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.

       In the case of a retirement plan (or multiple plans maintained by the
     same plan sponsor) which has established accounts with MFSC, on or after
     April 1, 2000 and is, at that time, a party to a retirement plan
     recordkeeping or administrative services agreement with MFD or one of its
     affiliates pursuant to which such services are provided with respect to at
     least $10 million in plan assets, MFD may retain the service fee paid by
     the fund with respect to shares purchased by such plan for the first year
     after purchase. Dealers will become eligible to receive the ongoing
     applicable service fee with respect to such shares commencing in the 13th
     month following purchase.

       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.

       The Fund has entered into an arrangement with State Street Brokerage
     Services, Inc. ("SSB"), an affiliate of the Custodian, under which, with
     respect to any brokerage transactions directed to SSB, the Fund receives,
     on a trade-by-trade basis, a credit for part of the brokerage commission
     paid, which is applied against other expenses of the Fund, including the
     Fund's custodian fee. The Adviser receives no direct or indirect benefit
     from this arrangement.

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

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

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

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

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

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

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

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

IX   PERFORMANCE INFORMATION

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

X    SHAREHOLDER SERVICES

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

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

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

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

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

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

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

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

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

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

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

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

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

     REINSTATEMENT PRIVILEGE -- Shareholders of the Fund and shareholders of the
     other MFS Funds (except MFS Money Market Fund, MFS Government Money Market
     Fund and holders of Class A shares of MFS Cash Reserve Fund in the case
     where shares of such funds are acquired through direct purchase or
     reinvested dividends) who have redeemed their shares have a one-time right
     to reinvest the redemption proceeds in any of the MFS Funds (if shares of
     the fund are available for sale) at net asset value (without a sales
     charge). For shareholders who exercise this privilege after redeeming class
     A or class C shares, if the redemption involved a CDSC, your account will
     be credited with the appropriate amount of the CDSC you paid; however, your
     new class A or class C shares (as applicable) will still be subject to a
     CDSC for up to one year from the date you originally purchased the shares
     redeemed.

       Until December 31, 2001, shareholders who redeem class B shares and then
     exercise their 90-day reinstatement privilege may reinvest their redemption
     proceeds either in

       o class B shares, in which case any applicable CDSC you paid on the
         redemption will be credited to your account, and your new shares will
         be subject to a CDSC which will be determined from the date you
         originally purchased the shares redeemed, or

       o class A shares, in which case the class A shares purchased will not be
         subject to a CDSC, but if you paid a CDSC when you redeemed your class
         B shares, your account will not be credited with the CDSC you paid.

       After December 31, 2001, shareholders who exercise their 90-day
     reinstatement privilege after redeeming class B shares may reinvest their
     redemption proceeds only in class A shares as described as the second
     option above.

       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.
     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.

     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.

        Recordkeeper Program).

II  WAIVERS OF CLASS A SALES CHARGES

          such agreement.

          $500,000 or more invested in shares of any class or classes 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
    redemption of all of its shares in the MFS Family of Funds, or (b) with
    respect to plans which establish an account with MFSC prior to November 1,
    1997, in the event that there is a change in law or regulations which

    becomes insolvent or bankrupt; (ii) is terminated under ERISA or is
    liquidated or dissolved; or (iii) is acquired by, merged into, or

    PURCHASES OF AT LEAST $5 MILLION (CDSC WAIVER ONLY)
      o Shares acquired of Eligible Funds (as defined below) if the
        shareholder's investment equals or exceeds $5 million in one or more
        Eligible Funds (the "Initial Purchase") (this waiver applies to the
        shares acquired from the Initial Purchase and all shares of Eligible
        Funds subsequently acquired by the shareholder); provided that the
        dealer through which the Initial Purchase is made enters into an
        agreement with MFD to accept delayed payment of commissions with respect
        to the Initial Purchase and all subsequent investments by the
        shareholder in the Eligible Funds subject to such requirements as may be
        established from time to time by MFD (for a schedule of the amount of
        commissions paid by MFD to the dealer on such investments, see
        "Purchases -- Class A Shares -- Purchases subject to a CDSC" in the
        Prospectus). The Eligible Funds are all funds included in the MFS Family

    INVESTMENT OF PROCEEDS FROM CERTAIN REDEMPTIONS OF CLASS I SHARES.
      o The initial sales charge imposed on purchases of Class A shares, and the
        contingent deferred sales charge imposed on certain redemptions of Class
        A shares, are waived with respect to Class A shares acquired of any of
        the MFS Funds through the immediate reinvestment of the proceeds of a
        redemption of Class I shares of any of the MFS Funds.

III WAIVERS OF CLASS B AND CLASS C SALES CHARGES
    In addition to the waivers set forth in Section I above, in the following
    circumstances the CDSC imposed on redemptions of Class B and Class C
    shares is waived:

    SYSTEMATIC WITHDRAWAL PLAN
      o Systematic Withdrawal Plan redemptions with respect to up to 10% per
        year (or 15% per year, in the case of accounts registered as IRAs where
        the redemption is made pursuant to Section 72(t) of the Internal Revenue
        Code of 1986, as amended) of the account value at the time of
        establishment.

    DEATH OF OWNER
      o Shares redeemed on account of the death of the account owner (e.g.,
        shares redeemed by the estate or any transferal of the shares from the
        estate) if the shares were held solely in the deceased individual's
        name, or for the benefit, of the deceased individual.

    DISABILITY OF OWNER
      o Shares redeemed on account of the disability of the account owner if
        shares are held either solely or jointly in the disabled individual's
        name or in a living trust for the benefit of the disabled individual (in
        which case a disability certification form is required to be submitted
        to MFSC).

    RETIREMENT PLANS.
    Shares redeemed on account of distributions made under the following
    circumstances:

      o IRAs, 401(a) Plans, ESP Plans and SRO Plans

        > Distributions made on or after the IRA owner or the 401(a), ESP or SRO
          Plan participant, as applicable, has attained the age of 70 1/2 years
          old, but only with respect to the minimum distribution under Code
          rules;

        > Salary Reduction Simplified Employee Pension Plans ("SAR-SEP Plans");

        > Distributions made on or after the SAR-SEP Plan participant has
          attained the age of 70 1/2 years old, but only with respect to the
          minimum distribution under applicable Code rules; and

        > Death or disability of a SAR-SEP Plan participant.

      o 401(a) and ESP Plans Only (Class B CDSC Waiver Only)

        > By a retirement plan whose sponsoring organization subscribes to the
          MFS Participant Recordkeeping System and which established an 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 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.

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

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

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

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

    COMMISSION
    PAID BY MFD
    TO DEALERS               CUMULATIVE PURCHASE AMOUNT
    ------------------------------------------------------
    1.00%                    On the first $2,000,000, plus
    0.80%                    Over $2,000,000 to $3,000,000, plus
    0.50%                    Over $3,000,000 to $50,000,000, plus
    0.25%                    Over $50,000,000

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

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

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

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

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

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

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

      For most of the MFS Funds:

      o In lieu of the sales commission and service fees normally paid by MFD to
        broker-dealers of record as described in the Prospectus, MFD has agreed
        to pay Bear, Stearns & Co. Inc. the following amounts with respect to
        Class A shares of the Fund purchased through a special retirement plan
        program offered by a third party administrator: (i) an amount equal to
        0.05% per annum of the average daily net assets invested in shares of
        the Fund pursuant to such program, and (ii) an amount equal to 0.20% of
        the net asset value of all net purchases of shares of the Fund made
        through such program, subject to a refund in the event that such shares
        are redeemed within 36 months.

      o Until terminated by MFD, MFD will incur, on behalf of H. D. Vest
        Investment Securities, Inc., the initial ticket charge of $15 with
        respect to purchases of shares of any MFS fund made through VESTADVISOR
        accounts. MFD will not incur such charge with respect to redemptions or
        repurchases of fund shares, exchanges of fund shares, or shares
        purchased or redeemed through systematic investment or withdrawal plans.

      o The following provisions shall apply to any retirement plan (each a
        "Merrill Lynch Daily K Plan") whose records are maintained on a daily
        valuation basis by either Merrill Lynch, Pierce, Fenner & Smith
        Incorporated ("Merrill Lynch"), or by an independent recordkeeper (an
        "Independent Recordkeeper") whose services are provided through a
        contract or alliance arrangement with Merrill Lynch, and with respect to
        which the sponsor of such plan has entered into a recordkeeping service
        agreement with Merrill Lynch (a "Merrill Lynch Recordkeeping
        Agreement").

        The initial sales charge imposed on purchases of Class A shares of the
        Funds, and the contingent deferred sales charge ("CDSC") imposed on
        certain redemptions of Class A shares of the Funds, is waived in the
        following circumstances with respect to a Merrill Lynch Daily K Plan:

        (i) if, on the date the Plan sponsor signs the Merrill Lynch
            Recordkeeping Agreement, such Plan has $3 million or more in
            assets invested in broker-dealer sold funds not advised or managed
            by Merrill Lynch Asset Management L.P. ("MLAM") that are made
            available pursuant to agreements between Merrill Lynch and such
            funds' principal underwriters or distributors, and in funds
            advised or managed by MLAM (collectively, the "Applicable
            Investments"); or

       (ii) if such Plan's records are maintained by an Independent
            Recordkeeper and, on the date the Plan sponsor signs the Merrill
            Lynch Recordkeeping Agreement, such Plan has $3 million or more in
            assets, excluding money market funds, invested in Applicable
            Investments; or

      (iii) such Plan has 500 or more eligible employees, as determined by the
            Merrill Lynch plan conversion manager on the date the Plan sponsor
            signs the Merrill Lynch Recordkeeping Agreement.

      The CDSC imposed on redemptions of Class B shares of the Fund is waived
      in the following circumstances with respect to a Merrill Lynch Daily K
      Plan:

        (i) if, on the date the Plan sponsor signs the Merrill Lynch
            Recordkeeping Agreement, such Plan has less than $3 million in
            assets invested in Applicable Investments;

       (ii) if such Plan's records are maintained by an independent
            recordkeeper and, on the date the Plan sponsor signs the Merrill
            Lynch Recordkeeping Agreement, such Plan has less than $3 million
            dollars in assets, excluding money market funds, invested in
            Applicable Investments; or

      (iii) such Plan has fewer than 500 eligible employees, as determined by
            the Merrill Lynch plan conversion manager on the date the Plan
            sponsor signs the Merrill Lynch Recordkeeping Agreement.

      No front-end commissions are paid with respect to any Class A or Class B
      shares of the Fund purchased by any Merrill Lynch Daily K Plan.

      o In lieu of the sales commission and service fees normally paid by MFD to
        borker-dealers of record as described in the Prospectus, MFD has agreed
        to pay Bear, Stearns & Co. Inc. the following amounts with respect to
        Class A shares of the Fund purchased through a special retirement plan
        program offered by a third party administrator: (i) an amount equal to
        0.05% per annum of the average daily net assets invested in shares of
        the Fund pursuant to such program, and (ii) an amount equal to 0.20% of
        the net asset value of all net purchases of shares of the Fund made
        through such program, subject to a refund in the event that such shares
        are redeemed within 36 months.

      For MFS Union Standard(R) Equity Fund:

      o The initial sales charge on Class A shares will be waived on shares
        purchased using redemption proceeds from a separate institutional
        account of Connecticut General Life Insurance Company with respect to
        which MFS Institutional Advisors, Inc. acts as investment adviser. No
        commissions will be payable to any dealer, bank or other financial
        intermediary with respect to shares purchased in this manner.

      For MFS Emerging Growth Fund, MFS Research Fund, MFS Capital
      Opportunities Fund and MFS Money Market Fund:

      o Class A shares of the Fund may be purchased at net asset value by one or
        more Chilean retirement plans, known as Administradores de Fondos de
        Pensiones, which are clients of the 1850 K Street N.W., Washington D.C.
        office of Dean Witter Reynolds, Inc. ("Dean Witter").

        MFD will waive any applicable contingent deferred sales charges upon
        redemption by such retirement plans on purchases of Class A shares over
        $1 million, provided that (i) in lieu of the commissions otherwise
        payable as specified in the prospectus, MFD will pay Dean Witter a
        commission on such purchases equal to 1.00% (including amounts in excess
        of $5 million) and (ii) if one or more such clients redeem all or a
        portion of these shares within three years after the purchase thereof,
        Dean Witter will reimburse MFD for the commission paid with respect to
        such shares on a pro rata basis based on the remaining portion of such
        three-year period.

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

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

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

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

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

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

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

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

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

    o   Sovereign Debt -- Investment in sovereign debt can involve a high degree
        of risk. The governmental entity that controls the repayment of
        sovereign debt may not be able or willing to repay the principal and/or
        interest when due in accordance with the terms of such debt. A
        governmental entity's willingness or ability to repay principal and
        interest due in a timely manner may be affected by, among other factors,
        its cash flow situation, the extent of its foreign reserves, the
        availability of sufficient foreign exchange on the date a payment is
        due, the relative size of the debt service burden to the economy as a
        whole, the governmental entity's policy towards the International
        Monetary Fund and the political constraints to which a governmental
        entity may be subject. Governmental entities may also be dependent on
        expected disbursements from foreign governments, multilateral agencies
        and others abroad to reduce principal and interest on their debt. The
        commitment on the part of these governments, agencies and others to make
        such disbursements may be conditioned on a governmental entity's
        implementation of economic reforms and/or economic performance and the
        timely service of such debtor's obligations. Failure to implement such
        reforms, achieve such levels of economic performance or repay principal
        or interest when due may result in the cancellation of such third
        parties' commitments to lend funds to the governmental entity, which may
        further impair such debtor's ability or willingness to service its debts
        in a timely manner. Consequently, governmental entities may default on
        their sovereign debt. Holders of sovereign debt (including the Fund) may
        be requested to participate in the rescheduling of such debt and to
        extend further loans to governmental entities. There is no bankruptcy
        proceedings by which sovereign debt on which governmental entities have
        defaulted may be collected in whole or in part.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

      A call option written by the Fund is "covered" if the Fund owns the
    security underlying the call or has an absolute and immediate right to
    acquire that security without additional cash consideration (or for
    additional cash consideration if the Fund owns liquid and unencumbered
    assets equal to the amount of cash consideration) upon conversion or
    exchange of other securities held in its portfolio. A call option is also
    covered if the Fund holds a call on the same security and in the same
    principal amount as the call written where the exercise price of the call
    held (a) is equal to or less than the exercise price of the call written or
    (b) is greater than the exercise price of the call written if the Fund owns
    liquid and unencumbered assets equal to the difference. A put option written
    by the Fund is "covered" if the Fund owns liquid and unencumbered assets
    with a value equal to the exercise price, or else holds a put on the same
    security and in the same principal amount as the put written where the
    exercise price of the put held is equal to or greater than the exercise
    price of the put written or where the exercise price of the put held is less
    than the exercise price of the put written if the Fund owns liquid and
    unencumbered assets equal to the difference. Put and call options written by
    the Fund may also be covered in such other manner as may be in accordance
    with the requirements of the exchange on which, or the counterparty with
    which, the option is traded, and applicable laws and regulations. If the
    writer's obligation is not so covered, it is subject to the risk of the full
    change in value of the underlying security from the time the option is
    written until exercise.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                           DESCRIPTION OF BOND RATINGS

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

                         MOODY'S INVESTORS SERVICE, INC.

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

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

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

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

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

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

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

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

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

                       STANDARD & POOR'S RATINGS SERVICES

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

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

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

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

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

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

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

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

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

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

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

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

    r: This symbol is attached to the ratings of instruments with significant
    noncredit risks. It highlights risks to principal or volatility of expected
    returns which are not addressed in the credit rating. Examples include:
    obligations linked or indexed to equities, currencies, or commodities;
    obligations exposed to severe prepayment risk -- such as interest-only or
    principal-only mortgage securities; and obligations with unusually risky
    interest terms, such as inverse floaters.

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

                            FITCH IBCA, DUFF & PHELPS

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

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

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

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

    Speculative Grade

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

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

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

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

    NOTES

    "+" or "-" may be appended to a rating to denote relative status within
    major rating categories. Such suffixes are not added to the "AAA" long-term
    rating category, or to categorize below "CCC".

    "NR" indicates that Fitch does not rate the issuer or issue in question.

    "WITHDRAWN": A rating is withdrawn when Fitch deems the amount of
    information available to be inadequate for rating purposes, or when an
    obligation matures, is called, or refinanced.

                           MFS(R) MID CAP GROWTH FUND


           Supplement dated January 1, 2001 to the Current Prospectus

This Supplement describes the fund's class I shares, and it supplements certain
information in the fund's Prospectus dated January 1, 2001. 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, 1999:


                                             1 Year      5 Years        Life#
                                             ------      -------        -----

      Class I shares                         78.85%       28.66%        24.86%

      Russell Midcap Growth Index+*          51.29%       28.02%        22.87%

      Average mid-cap growth fund++          72.86%       27.32%        22.40%


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

#     Fund performance figures are for the period from the commencement of the
      fund's investment operations on December 1, 1993 through December 31,
      1999. Index and Lipper average returns are from December 1, 1993.

+     Standard & Poor's Micropal, Inc.

++    Source: Lipper Inc.


*     The Russell Midcap Growth Index is a broad based, unmanaged index which
      measures the performance of the smallest growth companies in the Russell
      1000 Index. It is not possible to invest directly in an index.

The fund commenced investment operations on December 1, 1993 with the offering
of class A and class B 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.............................       0.75%

      Distribution and Service (12b-1) Fees.......       None

      Other Expenses..............................       0.24%
                                                         -----
      Total Annual Fund Operating Expenses(1).....       0.99%


--------------------------
(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, and may enter into other such
      arrangements and directed brokerage arrangements (which would also have
      the effect of reducing the fund's expenses). Any such fee reductions are
      not reflected under "Other Expenses."
<PAGE>

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.

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 I shares         $101         $315          $547          $1,213


4.    DESCRIPTION OF SHARE CLASSES

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

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

            =>    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, on behalf of their clients (i) initially
            invest at least $100,000 in class I shares of the fund or (ii) have,
            at the time of purchase of class I shares, aggregate assets of at
            least $10 million invested in class I shares of the fund either
            alone or in combination with investments in class I shares of other
            MFS Funds. MFD may accept purchases that do not meet these dollar
            qualification requirements if it believes, in its sole discretion,
            that these requirements will be met within a reasonable period of
            time. Additional investments may be made in any amount; 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.

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 investment objective is long-term growth of capital. The fund's
      objective may be changed without shareholder approval.

o     Principal Investment Policies

      The fund invests, under normal market conditions, at least 65% of its
      total assets in common stocks and related securities, such as preferred
      stocks, convertible securities and depositary receipts for those
      securities, of companies with medium market capitalizations which the
      fund's investment adviser, Massachusetts Financial Services Company
      (referred to as MFS or the adviser), believes have above-average growth
      potential.


      Medium market capitalization companies are defined by the fund as
      companies with market capitalizations equaling or exceeding $250 million
      but not exceeding the top of the Russell Midcap(TM) Growth Index range at
      the time of the fund's investment. This Index is a widely recognized,
      unmanaged index of mid-cap common stock prices. Companies whose market
      capitalizations fall below $250 million or exceed the top of the Russell
      Midcap(TM) Growth Index range after purchase continue to be considered
      medium-capitalization companies for purposes of the fund's 65% investment
      policy. As of November 30, 2000, the top of the Russell Midcap(TM) Growth
      Index range was $20 billion. The fund's investments may include securities
      listed on a securities exchange or traded in the over-the-counter markets.


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

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

      The fund may invest in foreign securities (including emerging markets
      securities) through which it may have exposure to foreign currencies.

      The fund has engaged and may engage in active and frequent trading to
      achieve its principal investment policies.

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.


                                       1
<PAGE>

      The principal risks of investing in the fund are:

      o     Mid-Cap Growth Company Risk: Prices of growth company securities
            held by the fund may decline due to changing economic, political or
            market conditions, or due to the financial condition of the company
            which issued the security, and may decline to a greater extent than
            the overall equity markets (e.g., as represented by the Standard and
            Poor's Composite 500 Index). Investments in medium capitalization
            companies can be riskier and more volatile than investments in
            companies with larger market capitalizations.


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


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

            o     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.

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

            o     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.

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

            o     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.


                                       2
<PAGE>


      o     Emerging Markets Risk: Emerging markets are generally defined as
            countries in the initial stages of their industrialization cycles
            with low per capita income. Emerging markets are generally more
            volatile than the markets of developed countries with more mature
            economies. All of the risks of investing in foreign securities
            described above are heightened by investing in emerging markets
            countries.


      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     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 a broad measure 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 B shares. 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 B returns shown
      in the bar chart, depending upon the expenses of those classes.


                  [The following information was represented by
                      a bar chart in the printed material.]

         3.00%     21.19%     18.78%      10.63%     19.50%      77.09%

      The total return for the nine month period ended September 30, 2000 was
      20.85%. During the period shown in the bar chart, the highest quarterly
      return was 39.49% (for the calendar quarter ended December 31, 1999) and
      the lowest quarterly return was (16.63)% (for the calendar quarter ended
      September 30, 1998).

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

      *     Fund performance figures are for the period from the commencement of
            the fund's investment operations on December 1, 1993 through
            December 31, 1999. Index and Lipper average returns are from
            December 1, 1993.

      **    The Russell Midcap Growth Index is a broad based, unmanaged index
            which measures the performance of the smallest growth companies in
            the Russell 1000 Index. It is not possible to invest directly in an
            index.

      Class A share performance takes into account the deduction of the 5.75%
      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 December 1, 1993 with the
      offering of class A and class B shares and subsequently offered class C
      shares on August 1, 1994. Class C share performance include the
      performance of the fund's class B shares for periods prior to the offering
      of class C shares. This blended class C share performance has been
      adjusted to take into account the CDSC applicable to class C shares,
      rather than the CDSC applicable to class B shares. Because operating
      expenses of class B and C shares are similar, this blended class C share
      performance is also similar to what the performance of class C shares
      would have been had class C shares been offered for the entire period.

</TABLE>

      ----------
      (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 either 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). The class A distribution fee is not currently in
            effect, and may equal up to 0.10% annually upon implementation by
            the board of trustees which oversees the fund.

      (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                           $694     $946    $1,217   $1,989
      Class B shares(1)
        Assuming redemption at end of period   $602     $924    $1,273   $2,123
        Assuming no redemption                 $202     $624    $1,073   $2,123
      Class C shares
        Assuming redemption at end of period   $302     $624    $1,073   $2,317
        Assuming no redemption                 $202     $624    $1,073   $2,317


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

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

o     Further Information on Investment Strategies and Risks

      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 $137.95 billion as of November 30,
      2000.

      MFS provides investment management and related administrative services and
      facilities to the fund, including portfolio management and trade
      execution. For the fiscal year ended August 31, 2000 the fund paid MFS an
      aggregate management fee equal to the management fee ratio as set forth in
      the "Expense Summary" above.


o     Portfolio Manager


      Mark Regan, a Senior Vice President of MFS, has been employed in the
      investment management area of MFS since 1989 and has been the portfolio
      manager of the fund since the fund's inception in December 1993. David E.

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

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


                                       10
<PAGE>

      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

            o     the plan had established an account with MFSC; and

            o     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 (referred to as 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


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

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

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


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

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


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

                  The retirement plans will qualify under this category only if
                  their plans or their sponsoring organization informs MFSC
                  prior to the purchases that the plans have a market value of
                  $500,000 or more invested in shares of any class or classes of
                  the MFS funds; MFSC has no obligation independently to
                  determine whether such plans qualify under this category; and



                                       11
<PAGE>

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


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

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


            o     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.


                                       12
<PAGE>

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 (0.10% distribution fee and 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. The 0.10% per annum class A
      distribution fee is currently not being imposed and will be paid by the
      fund when the Trustees of the fund approve the fee.

--------------------------------------------------------------------------------
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:


            o     a tax-deferred retirement program (other than IRA) where
                  investments are made by means of group remittal statements; or

            o     an employer sponsored investment program.

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


      Adding to Your Account. There are several easy ways you can make
      additional investments of at least $50 to your account:

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

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

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

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

o     How to Exchange Shares

      You can exchange your shares for shares of the same class of certain other
      MFS funds at net asset value by having your financial adviser process your
      exchange request or by contacting MFSC directly. The minimum exchange
      amount is generally $1,000 ($50 for exchanges made under the automatic
      exchange plan). Shares otherwise subject to a CDSC will not be charged a
      CDSC in an exchange. However, when you redeem the shares acquired through
      the exchange,


                                       14
<PAGE>

      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 which are policies designed to protect the funds and their
      shareholders from the adverse effect of frequent exchanges. These
      limitations and market timing 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.


                                       15
<PAGE>

      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).

      For shareholders who exercise this privilege after redeeming class A or
      class C shares, if the redemption involved a CDSC, your account will be
      credited with the appropriate amount of the CDSC you paid; however, your
      new class A or class C shares (as applicable) will still be subject to a
      CDSC for up to one year from the date you originally purchased the shares
      redeemed.



                                       16
<PAGE>


      Until December 31, 2001, shareholders who redeem class B shares and then
      exercise their 90-day reinstatement privilege may reinvest their
      redemption proceeds either in

      o     class B shares, in which case any applicable CDSC you paid on the
            redemption will be credited to your account, and your new shares
            will be subject to a CDSC which will be determined from the date you
            originally purchased the shares redeemed, or

      o     class A shares, in which case the class A shares purchased will not
            be subject to an initial sales charge or a CDSC, but if you paid a
            CDSC when you redeemed your class B shares, your account will not be
            credited with the CDSC you paid.

      After December 31, 2001, shareholders who exercise their 90-day
      reinstatement privilege after redeeming class B shares may reinvest their
      redemption proceeds only in class A shares as described as the second
      option above.


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

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

      o     Dividend and capital gain distributions in cash.

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


o     Purchase and Redemption Programs

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

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

      Automatic Exchange Plan. If you have an account balance of at least $5,000
      in any MFS fund, you may participate in the automatic exchange plan, a
      dollar-cost averaging program. This plan permits you to make automatic
      monthly or quarterly exchanges from your account in an MFS fund for shares
      of the same class of shares of other MFS funds. You may make exchanges of
      at least $50 to up to six different funds under this plan. Exchanges will
      generally be made at net asset value without any sales charges. If you
      exchange shares out of the MFS Money Market Fund or MFS Government Money
      Market Fund, or if you exchange class A shares out of


                                       18
<PAGE>

      the MFS Cash Reserve Fund, into class A shares of any other MFS fund, you
      will pay the initial sales charge if you have not already paid this charge
      on these shares.

      Reinvest Without a Sales Charge. You can reinvest dividend and capital
      gain distributions into your account without a sales charge to add to your
      investment easily and automatically.

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

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

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

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

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

o     Pricing of Fund Shares

      The price of each class of 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
      ("NYSE") is open for trading (generally, 4:00 p.m., Eastern time)
      (referred to as the valuation time). The NYSE is closed on most national
      holidays and Good Friday. 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 (including any
      realized net capital gains) to shareholders as dividends 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.


                                       20
<PAGE>

      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
      investment goals and principal investment policies and risks similar to
      those of 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     Provision of Annual and Semiannual Reports and Prospectuses


      The fund produces financial reports every six months and updates its
      prospectus annually. To avoid sending duplicate copies of materials to
      households, only one copy of the fund's annual and semiannual and
      prospectus 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 and prospectus 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.

II    MANAGEMENT OF THE FUND

      The Fund

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


      The Fund and its Adviser and Distributor have adopted a code of ethics as
      required under the Investment Company Act of 1940 (the "1940 Act").
      Subject to certain conditions and restrictions, this code permits
      personnel subject to the code to invest in securities for their own
      accounts, including securities that may be purchased, held or sold by the
      Fund. Securities transactions by some of these persons may be subject to
      prior approval of the Adviser's Compliance Department. Securities
      transactions of certain personnel are subject to quarterly reporting and
      review requirements. The code is on public file with, and is available
      from, the SEC. See the back cover of the prospectus for information on
      obtaining a copy.


      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.

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

IV    PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS

      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 $43,800
      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 Inc. (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
      any, and by investors who own 5% or more of any class of Fund shares, if
      any, is set forth in Appendix F to this Part I.

VI    PERFORMANCE INFORMATION

      Performance information, as quoted by the Fund in sales literature and
      marketing materials, is set forth in Appendix G to this Part I.

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.


                                   Part I -- 1
<PAGE>

      The following percentage limitations apply to these investment techniques
      and practices:

      o     Foreign Securities may be up to (but not including) 20% of net
            assets

      o     Lower Rated Bonds may not exceed 10% of 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 the Fund or class, as applicable, or
      (ii) 67% or more of the outstanding shares of the Trust or the Fund or
      class, as applicable, present at a meeting at which holders of more than
      50% of the outstanding shares of the Trust or the Fund or class, as
      applicable, are represented in person or by proxy). Except with respect to
      the Fund's policy on borrowing and investing in illiquid securities, 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 policy. In the event of
      a violation of non-fundamental policy (1), the Fund will reduce the
      percentage of its assets invested in illiquid investments in due course,
      taking into account the best interest of shareholders.

      The Fund may not:

      (1)   borrow amounts in excess of 33 1/3% of its assets including amounts
            borrowed, and then only as a temporary measure for extra-ordinary or
            emergency purposes;

      (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)   purchase or sell real estate (including limited partnership
            interests but excluding securities secured by real estate or
            interests therein and securities of companies, such as real estate
            investment trusts, which deal in real estate or interests therein),
            interests in oil, gas or mineral leases, commodities or commodity
            contracts (excluding options on securities, stock indexes and
            foreign currency ("Options"), Options on Futures Contracts and any
            other type of option, Futures Contracts and any other type of
            futures contract and Forward Contracts) in the ordinary course of
            its business. The Fund reserves the freedom of action to hold and to
            sell real estate, mineral leases, commodities or commodity contracts
            (including Options, Options on Future Contracts, and any other type
            of option, Futures Contracts, any other type of futures contract and
            Forward Contracts) acquired as a result of the ownership of
            securities;

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

      (5)   make loans to other persons. For these purposes, the purchase of
            short-term commercial paper, the purchase of a portion or all of an
            issue of debt securities, the lending of portfolio securities, or
            the investment of 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, more than 25% of its gross assets would be invested in
            securities of issuers whose principal business activities are in the
            same industry (except obligations issued or guaranteed by the U.S.
            Government or its agencies, and instrumentalities and repurchase
            agreements collateralized by such obligations).


      In addition, the Fund has the following non-fundamental policies which
      may be changed without shareholder approval. The 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), 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. Securities that are determined to be liquid by the
            Trust's Board of Trustees (or its delegee), will not be subject to
            this 15% limitation;

      (2)   invest more than 5% of the value of the Fund's net assets, valued at
            the lower of cost or market, in warrants. Included within such
            amount, but not to exceed 2% of the value of the Fund's net assets,
            may be warrants which are not listed on the New York or American
            Stock Exchange. Warrants acquired by the Fund in units or attached
            to securities may be deemed to be without value;

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

      (4)   purchase or retain securities of an issuer any of whose officers,
            directors, trustees or security holders is an officer or Trustee of
            the Trust, or is an officer or a director of the investment adviser
            of the Fund, if one or more of such persons also owns beneficially
            more than 0.5% of the securities of such issuer, and such persons
            owning


                                   Part I -- 2
<PAGE>

            more than 0.5% of such securities together own beneficially more
            than 5% of such securities;

      (5)   purchase any securities or evidences of interest therein on margin,
            except that the Fund may obtain such short-term credit as may be
            necessary for the clearance of any transaction and except that the
            Fund may make margin deposits in connection with any type of option
            (including Options on Futures Contracts, and options), any type of
            futures contract (including Futures Contracts), and Forward
            Contracts;

      (6)   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;

      (7)   invest more than 5% of its gross assets in companies which,
            including predecessors, controlling persons, sponsoring entities,
            general partners and guarantors, have a record of less than three
            years' continuous operation or relevant business experience;

      (8)   pledge, mortgage or hypothecate in excess of 33 1/2% its gross
            assets. For purposes of this restriction, collateral arrangements
            with respect to any type of option (including Options on Futures
            Contracts and Options), any futures contract (including Futures
            Contracts), and Forward Contracts, and payments of initial and
            variation margin in connection therewith, are not considered a
            pledge of assets;

      (9)   purchase or sell any put or call option or any combination thereof,
            provided that this shall not prevent (a) the purchase, ownership,
            holding or sale of (i) warrants where the grantor of the warrants is
            the issuer of the underlying securities or (ii) put or call options
            or combinations thereof with respect to securities, indices of
            securities, Options on Foreign Currencies, or any type of futures
            contract (including Futures Contracts) or (b) the purchase,
            ownership, holding or sale of contracts for the future delivery of
            securities or currencies; or

      (10)  invest 25% or more of the market value of its total assets in
            securities of issuers in any one industry.

</TABLE>


----------
*     From commencement of the Fund's investment operations on December 1, 1993.

The Fund commenced investment operations on December 1, 1993, with the offering
of class A shares and class B shares, and subsequently offered class C and class
I shares on August 1, 1994 and January 2, 1997, respectively. Class C share
performance includes the performance of the Fund's class B shares for periods
prior to the offering of class C shares. This blended class C share performance
has been adjusted to take into account the CDSC applicable to class C shares
rather than the CDSC applicable to class B 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 similar, this
blended class C share performance is similar to what the performance of C shares
would have been had class C shares been offered for the entire period.

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 what the
performance of class I shares would have been had class I 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 -- Each Trust (except MFS Series Trust XI) 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 "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 of up to 0.0175% on the first $2.0 billion;
     0.0130% on the next $2.5 billion; 0.0005% on the next $2.5 billion; and
     0.0% on amounts in excess of $7.0 billion, 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.

     CODE OF ETHICS
     The Fund and its Adviser and Distributor have adopted a code of ethics as
     required under the Investment Company Act of 1940 ("the 1940 Act"). Subject
     to certain conditions and restrictions, this code permits personnel subject
     to the code to invest in securities for their own accounts, including
     securities that may be purchased, held or sold by the Fund. Securities
     transactions by some of these persons may be subject to prior approval of
     the Adviser's Compliance Department. Securities transactions of certain
     personnel are subject to quarterly reporting and review requirements. The
     code is on public file with, and is available from, the SEC. See the back
     cover of the prospectus for information on obtaining a copy.

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.

       In the case of a retirement plan (or multiple plans maintained by the
     same plan sponsor) which has established accounts with MFSC, on or after
     April 1, 2000 and is, at that time, a party to a retirement plan
     recordkeeping or administrative services agreement with MFD or one of its
     affiliates pursuant to which such services are provided with respect to at
     least $10 million in plan assets, MFD may retain the service fee paid by
     the fund with respect to shares purchased by such plan for the first year
     after purchase. Dealers will become eligible to receive the ongoing
     applicable service fee with respect to such shares commencing in the 13th
     month following purchase.

       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.

       The Fund has entered into an arrangement with State Street Brokerage
     Services, Inc. ("SSB"), an affiliate of the Custodian, under which, with
     respect to any brokerage transactions directed to SSB, the Fund receives,
     on a trade-by-trade basis, a credit for part of the brokerage commission
     paid, which is applied against other expenses of the Fund, including the
     Fund's custodian fee. The Adviser receives no direct or indirect benefit
     from this arrangement.

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

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

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

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

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

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

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

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

IX   PERFORMANCE INFORMATION

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

X    SHAREHOLDER SERVICES

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

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

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

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

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

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

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

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

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

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

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

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

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

     REINSTATEMENT PRIVILEGE -- Shareholders of the Fund and shareholders of the
     other MFS Funds (except MFS Money Market Fund, MFS Government Money Market
     Fund and holders of Class A shares of MFS Cash Reserve Fund in the case
     where shares of such funds are acquired through direct purchase or
     reinvested dividends) who have redeemed their shares have a one-time right
     to reinvest the redemption proceeds in any of the MFS Funds (if shares of
     the fund are available for sale) at net asset value (without a sales
     charge). For shareholders who exercise this privilege after redeeming class
     A or class C shares, if the redemption involved a CDSC, your account will
     be credited with the appropriate amount of the CDSC you paid; however, your
     new class A or class C shares (as applicable) will still be subject to a
     CDSC for up to one year from the date you originally purchased the shares
     redeemed.

       Until December 31, 2001, shareholders who redeem class B shares and then
     exercise their 90-day reinstatement privilege may reinvest their redemption
     proceeds either in

       o class B shares, in which case any applicable CDSC you paid on the
         redemption will be credited to your account, and your new shares will
         be subject to a CDSC which will be determined from the date you
         originally purchased the shares redeemed, or

       o class A shares, in which case the class A shares purchased will not be
         subject to a CDSC, but if you paid a CDSC when you redeemed your class
         B shares, your account will not be credited with the CDSC you paid.

       After December 31, 2001, shareholders who exercise their 90-day
     reinstatement privilege after redeeming class B shares may reinvest their
     redemption proceeds only in class A shares as described as the second
     option above.

       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.
     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.

          and (ii) such distribution proceeds result from the redemption or
          liquidation of plan investments other than the MFS Funds for which
          retirement plan recordkeeping services are provided under the terms of
          such agreement.

    SHARES REDEEMED ON ACCOUNT OF DISTRIBUTIONS

          plan has, at the time of certification or will have pursuant to a
          purchase order placed with the certification, a market value of
          $500,000 or more invested in shares of any class or classes 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
    redemption of all of its shares in the MFS Family of Funds, or (b) with
    respect to plans which establish an account with MFSC prior to November 1,
    1997, in the event that there is a change in law or regulations which
    result 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.

        Funds subsequently acquired by the shareholder); provided that the
        dealer through which the Initial Purchase is made enters into an
        agreement with MFD to accept delayed payment of commissions with respect
        to the Initial Purchase and all subsequent investments by the
        shareholder in the Eligible Funds subject to such requirements as may be
        established from time to time by MFD (for a schedule of the amount of
        commissions paid by MFD to the dealer on such investments, see
        "Purchases -- Class A Shares -- Purchases subject to a CDSC" in the

        for the benefit of their trust account clients.

    INVESTMENT OF PROCEEDS FROM CERTAIN REDEMPTIONS OF CLASS I SHARES.
      o The initial sales charge imposed on purchases of Class A shares, and the
        contingent deferred sales charge imposed on certain redemptions of Class
        A shares, are waived with respect to Class A shares acquired of any of
        the MFS Funds through the immediate reinvestment of the proceeds of a
        redemption of Class I shares of any of the MFS Funds.

III WAIVERS OF CLASS B AND CLASS C SALES CHARGES

        Code of 1986, as amended) of the account value at the time of
        establishment.

    DEATH OF OWNER
      o Shares redeemed on account of the death of the account owner (e.g.,

          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 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.

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

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

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

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

    COMMISSION
    PAID BY MFD
    TO DEALERS               CUMULATIVE PURCHASE AMOUNT
    ------------------------------------------------------
    1.00%                    On the first $2,000,000, plus
    0.80%                    Over $2,000,000 to $3,000,000, plus
    0.50%                    Over $3,000,000 to $50,000,000, plus
    0.25%                    Over $50,000,000

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

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

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

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

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

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

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

      For most of the MFS Funds:

      o In lieu of the sales commission and service fees normally paid by MFD to
        broker-dealers of record as described in the Prospectus, MFD has agreed
        to pay Bear, Stearns & Co. Inc. the following amounts with respect to
        Class A shares of the Fund purchased through a special retirement plan
        program offered by a third party administrator: (i) an amount equal to
        0.05% per annum of the average daily net assets invested in shares of
        the Fund pursuant to such program, and (ii) an amount equal to 0.20% of
        the net asset value of all net purchases of shares of the Fund made
        through such program, subject to a refund in the event that such shares
        are redeemed within 36 months.

      o Until terminated by MFD, MFD will incur, on behalf of H. D. Vest
        Investment Securities, Inc., the initial ticket charge of $15 with
        respect to purchases of shares of any MFS fund made through VESTADVISOR
        accounts. MFD will not incur such charge with respect to redemptions or
        repurchases of fund shares, exchanges of fund shares, or shares
        purchased or redeemed through systematic investment or withdrawal plans.

      o The following provisions shall apply to any retirement plan (each a
        "Merrill Lynch Daily K Plan") whose records are maintained on a daily
        valuation basis by either Merrill Lynch, Pierce, Fenner & Smith
        Incorporated ("Merrill Lynch"), or by an independent recordkeeper (an
        "Independent Recordkeeper") whose services are provided through a
        contract or alliance arrangement with Merrill Lynch, and with respect to
        which the sponsor of such plan has entered into a recordkeeping service
        agreement with Merrill Lynch (a "Merrill Lynch Recordkeeping
        Agreement").

        The initial sales charge imposed on purchases of Class A shares of the
        Funds, and the contingent deferred sales charge ("CDSC") imposed on
        certain redemptions of Class A shares of the Funds, is waived in the
        following circumstances with respect to a Merrill Lynch Daily K Plan:

        (i) if, on the date the Plan sponsor signs the Merrill Lynch
            Recordkeeping Agreement, such Plan has $3 million or more in
            assets invested in broker-dealer sold funds not advised or managed
            by Merrill Lynch Asset Management L.P. ("MLAM") that are made
            available pursuant to agreements between Merrill Lynch and such
            funds' principal underwriters or distributors, and in funds
            advised or managed by MLAM (collectively, the "Applicable
            Investments"); or

       (ii) if such Plan's records are maintained by an Independent
            Recordkeeper and, on the date the Plan sponsor signs the Merrill
            Lynch Recordkeeping Agreement, such Plan has $3 million or more in
            assets, excluding money market funds, invested in Applicable
            Investments; or

      (iii) such Plan has 500 or more eligible employees, as determined by the
            Merrill Lynch plan conversion manager on the date the Plan sponsor
            signs the Merrill Lynch Recordkeeping Agreement.

      The CDSC imposed on redemptions of Class B shares of the Fund is waived
      in the following circumstances with respect to a Merrill Lynch Daily K
      Plan:

        (i) if, on the date the Plan sponsor signs the Merrill Lynch
            Recordkeeping Agreement, such Plan has less than $3 million in
            assets invested in Applicable Investments;

       (ii) if such Plan's records are maintained by an independent
            recordkeeper and, on the date the Plan sponsor signs the Merrill
            Lynch Recordkeeping Agreement, such Plan has less than $3 million
            dollars in assets, excluding money market funds, invested in
            Applicable Investments; or

      (iii) such Plan has fewer than 500 eligible employees, as determined by
            the Merrill Lynch plan conversion manager on the date the Plan
            sponsor signs the Merrill Lynch Recordkeeping Agreement.

      No front-end commissions are paid with respect to any Class A or Class B
      shares of the Fund purchased by any Merrill Lynch Daily K Plan.

      o In lieu of the sales commission and service fees normally paid by MFD to
        borker-dealers of record as described in the Prospectus, MFD has agreed
        to pay Bear, Stearns & Co. Inc. the following amounts with respect to
        Class A shares of the Fund purchased through a special retirement plan
        program offered by a third party administrator: (i) an amount equal to
        0.05% per annum of the average daily net assets invested in shares of
        the Fund pursuant to such program, and (ii) an amount equal to 0.20% of
        the net asset value of all net purchases of shares of the Fund made
        through such program, subject to a refund in the event that such shares
        are redeemed within 36 months.

      For MFS Union Standard(R) Equity Fund:

      o The initial sales charge on Class A shares will be waived on shares
        purchased using redemption proceeds from a separate institutional
        account of Connecticut General Life Insurance Company with respect to
        which MFS Institutional Advisors, Inc. acts as investment adviser. No
        commissions will be payable to any dealer, bank or other financial
        intermediary with respect to shares purchased in this manner.

      For MFS Emerging Growth Fund, MFS Research Fund, MFS Capital
      Opportunities Fund and MFS Money Market Fund:

      o Class A shares of the Fund may be purchased at net asset value by one or
        more Chilean retirement plans, known as Administradores de Fondos de
        Pensiones, which are clients of the 1850 K Street N.W., Washington D.C.
        office of Dean Witter Reynolds, Inc. ("Dean Witter").

        MFD will waive any applicable contingent deferred sales charges upon
        redemption by such retirement plans on purchases of Class A shares over
        $1 million, provided that (i) in lieu of the commissions otherwise
        payable as specified in the prospectus, MFD will pay Dean Witter a
        commission on such purchases equal to 1.00% (including amounts in excess
        of $5 million) and (ii) if one or more such clients redeem all or a
        portion of these shares within three years after the purchase thereof,
        Dean Witter will reimburse MFD for the commission paid with respect to
        such shares on a pro rata basis based on the remaining portion of such
        three-year period.

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

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

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

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

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

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

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

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

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

    o   Sovereign Debt -- Investment in sovereign debt can involve a high degree
        of risk. The governmental entity that controls the repayment of
        sovereign debt may not be able or willing to repay the principal and/or
        interest when due in accordance with the terms of such debt. A
        governmental entity's willingness or ability to repay principal and
        interest due in a timely manner may be affected by, among other factors,
        its cash flow situation, the extent of its foreign reserves, the
        availability of sufficient foreign exchange on the date a payment is
        due, the relative size of the debt service burden to the economy as a
        whole, the governmental entity's policy towards the International
        Monetary Fund and the political constraints to which a governmental
        entity may be subject. Governmental entities may also be dependent on
        expected disbursements from foreign governments, multilateral agencies
        and others abroad to reduce principal and interest on their debt. The
        commitment on the part of these governments, agencies and others to make
        such disbursements may be conditioned on a governmental entity's
        implementation of economic reforms and/or economic performance and the
        timely service of such debtor's obligations. Failure to implement such
        reforms, achieve such levels of economic performance or repay principal
        or interest when due may result in the cancellation of such third
        parties' commitments to lend funds to the governmental entity, which may
        further impair such debtor's ability or willingness to service its debts
        in a timely manner. Consequently, governmental entities may default on
        their sovereign debt. Holders of sovereign debt (including the Fund) may
        be requested to participate in the rescheduling of such debt and to
        extend further loans to governmental entities. There is no bankruptcy
        proceedings by which sovereign debt on which governmental entities have
        defaulted may be collected in whole or in part.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

      A call option written by the Fund is "covered" if the Fund owns the
    security underlying the call or has an absolute and immediate right to
    acquire that security without additional cash consideration (or for
    additional cash consideration if the Fund owns liquid and unencumbered
    assets equal to the amount of cash consideration) upon conversion or
    exchange of other securities held in its portfolio. A call option is also
    covered if the Fund holds a call on the same security and in the same
    principal amount as the call written where the exercise price of the call
    held (a) is equal to or less than the exercise price of the call written or
    (b) is greater than the exercise price of the call written if the Fund owns
    liquid and unencumbered assets equal to the difference. A put option written
    by the Fund is "covered" if the Fund owns liquid and unencumbered assets
    with a value equal to the exercise price, or else holds a put on the same
    security and in the same principal amount as the put written where the
    exercise price of the put held is equal to or greater than the exercise
    price of the put written or where the exercise price of the put held is less
    than the exercise price of the put written if the Fund owns liquid and
    unencumbered assets equal to the difference. Put and call options written by
    the Fund may also be covered in such other manner as may be in accordance
    with the requirements of the exchange on which, or the counterparty with
    which, the option is traded, and applicable laws and regulations. If the
    writer's obligation is not so covered, it is subject to the risk of the full
    change in value of the underlying security from the time the option is
    written until exercise.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                           DESCRIPTION OF BOND RATINGS

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

                         MOODY'S INVESTORS SERVICE, INC.

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

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

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

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

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

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

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

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

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

                       STANDARD & POOR'S RATINGS SERVICES

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

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

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

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

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

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

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

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

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

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

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

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

    r: This symbol is attached to the ratings of instruments with significant
    noncredit risks. It highlights risks to principal or volatility of expected
    returns which are not addressed in the credit rating. Examples include:
    obligations linked or indexed to equities, currencies, or commodities;
    obligations exposed to severe prepayment risk -- such as interest-only or
    principal-only mortgage securities; and obligations with unusually risky
    interest terms, such as inverse floaters.

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

                            FITCH IBCA, DUFF & PHELPS

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

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

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

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

    Speculative Grade

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

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

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

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

    NOTES

    "+" or "-" may be appended to a rating to denote relative status within
    major rating categories. Such suffixes are not added to the "AAA" long-term
    rating category, or to categorize below "CCC".

    "NR" indicates that Fitch does not rate the issuer or issue in question.

    "WITHDRAWN": A rating is withdrawn when Fitch deems the amount of
    information available to be inadequate for rating purposes, or when an
    obligation matures, is called, or refinanced.
