                      Supplement to the Current Prospectus

     Effective as of January 1, 1995, MFS Fund Distributors, Inc. ("MFD") has
replaced MFS Financial Services, Inc. ("FSI") as the Fund's distributor. Both
MFD and FSI are wholly-owned subsidiaries of Massachusetts Financial Services
Company ("MFS"), the Fund's investment adviser.

     Class A shares of the Fund may be purchased at net asset value by certain
retirement plans subject to the Employee Retirement Income Security Act of 1974,
as amended, subject to the following:
      (i) The sponsoring organization must demonstrate to the satisfaction of
          MFD that either (a) the employer has at least 25 employees or (b) the
          aggregate purchases by the retirement plan of Class A shares of the
          Funds will be in an amount of at least $250,000 within a reasonable
          period of time, as determined by MFD in its sole discretion; and
     (ii) A contingent deferred sales charge of 1% will be imposed on such
          purchases in the event of certain redemption transactions within 12
          months following such purchases.

     Class A shares may be sold at net asset value, subject to appropriate
documentation, through a dealer where the amount invested represents redemption
proceeds from a registered open-end management investment company not
distributed or managed by MFD or its affiliates if: (i) the redeemed shares were
subject to an initial sales charge or a deferred sales charge (whether or not
actually imposed); (ii) such redemption has occurred no more than 90 days prior
to the purchase of Class A shares of the Fund; and (iii) the Fund, MFD or its
affiliates have not agreed with such company or its affiliates, formally or
informally, to sell Class A shares at net asset value or provide any other
incentive with respect to such redemption and sale.

     Class A shares of the Fund may be purchased at net asset value by
retirement plans whose third party administrators have entered into an
administrative services agreement with MFD or one or more of its affiliates to
perform certain administrative services, subject to certain operational
requirements specified from time to time by MFD or one or more of its
affiliates.

                                                                          (Over)

<PAGE>

     Class A shares of the Fund (except of the MFS municipal bond funds
identified above) may be purchased at net asset value by retirement plans
qualified under Section 401(k) of the Code through certain broker-dealers and
other financial institutions which have entered into an agreement with MFD which
includes certain minimum size qualifications for such retirement plans and
provides that the broker-dealer or other financial institution will perform
certain administrative services with respect to the plan's account.

     The CDSC on Class A and Class B shares will be waived upon redemption by a
retirement plan where the redemption proceeds are used to pay expenses of the
retirement plan or certain expenses of participants under the retirement plan
(e.g., participant account fees), provided that the retirement plan's sponsor
subscribes to the MFS Fundamental 401(k) Plan (sm) or another similar
recordkeeping system made available by MFS Service Center, Inc. (the
"Shareholder Servicing Agent").

     The CDSC on Class A and B shares will be waived upon the transfer of
registration from shares held by a retirement plan through a single account
maintained by the Shareholder Servicing Agent to multiple Class A and B share
accounts, respectively, maintained by the Shareholder Servicing Agent on behalf
of individual participants in the retirement plan, provided that the retirement
plan's sponsor subscribes to the MFS Fundamental 401(k) Plan(sm) or another
similar recordkeeping system made available by the Shareholder Servicing Agent.

     The applicability of a CDSC will be unaffected by exchanges or transfers of
registration, except that, with respect to transfers of registration to an IRA
rollover account, the CDSC will be waived if the shares being reregistered would
have been eligible for a CDSC waiver had they been redeemed.

     The current Prospectus discloses that "Class A shares of the Fund may also
be purchased at net asset value where the purchase is in an amount of $3 million
or more and where the dealer and FSI enter into an agreement in which the dealer
agrees to return any commission paid to it on the sale (or a pro rata portion
thereof as described above if the shareholder redeems his or her shares within
one year of purchase. (Shareholders who purchase shares at NAV pursuant to these
conditions are called ("$3 Million Shareholders")." This policy is terminated
effective as of the date of this Supplement and the above-referenced language,
and all references to "$3 Million Shareholders," are deleted from the
Prospectus.

     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 shares of certain specified Funds sold by such dealer
during a specified sales period.

     If a shareholder has elected to receive dividends and/or capital gain
distributions in cash and the postal or other delivery service is unable to
deliver checks to the shareholder's address of record, such shareholder's
distribution option will automatically be converted to reinvest all dividends
and other distributions reinvested in additional shares.

     From time to time, MFS may direct certain portfolio transactions to
broker-dealer firms which, in turn, have agreed to pay a portion of the Fund's
operating expenses (e.g., fees charged by the custodian of the Fund's assets).

                The date of this Supplement is January 13, 1995.

Edwards") 100% of the applicable sales charge on sales of Class A shares of each
of the funds listed above (the "Funds") sold for investment in Individual
Retirement Accounts ("IRAs") (excluding SEP-IRAs). In addition, MFD will pay A.

                      Supplement to the Current Prospectus

Effective immediately, the Funds have expanded their policies with respect to
exchanges effected by market timers to be as follows:

     FSI may enter into an agreement with shareholders who intend to make
     exchanges among certain classes of certain MFS Funds (as determined by FSI)
     which follow a timing pattern, and with individuals or entities acting on
     such shareholders' behalf (collectively, "market timers"), setting forth
     the terms, procedures and restrictions with respect to such exchanges. In
     the absence of such an agreement, it i5 the policy of the Fund and FSI to
     reject or restrict purchases by market timers if (i) more than two exchange
     purchases are effected in a timed account in the same calendar quarter or
     (ii) a purchase would result in shares being held in timed accounts by
     market timers representing more than (x) one percent of the Fund's net
     assets or (y) specified dollar amounts in the case of certain MFS Funds
     which may include the Fund and which may change from time to time. The Fund
     and FSI each reserve the right to request market timers to redeem their
     shares at net asset value, less any applicable CDSC, if either of these
     restrictions is violated.

                 The date of this Supplement is April 1, 1994.

1. THE FUND 
MFS Managed Sectors Fund (the "Fund") is a non-diversified series of MFS 
Series Trust I (the "Trust"), an open-end management investment company which 
was organized as a business trust under the laws of The Commonwealth of 
Massachusetts on July 30, 1986. The Trust presently consists of two series of 
shares, each of which represents a portfolio with separate investment 
policies. Shares of the Fund are continuously sold to the public and the Fund 
then uses the proceeds to buy securities for its portfolio. Two classes of 
shares of the Fund currently are offered to the general public. Class A 
shares are offered at net asset value plus an initial sales charge (or a 
contingent deferred sales charge (a "CDSC") in the case of certain purchases 
of $1 million or more) and subject to a Distribution Plan, providing for an 
annual distribution fee and service fee. Class B shares are offered at net 
asset value without an initial sales charge but subject to a CDSC and a 
Distribution Plan providing for an annual distribution fee and service fee 
which are greater than the Class A distribution fee and service fee; Class B 
shares will convert automatically to Class A shares approximately eight years 
after purchase. 

The Trust's Board of Trustees provides broad supervision over the affairs of 
the Fund. Massachusetts Financial Services Company, a Delaware corporation 
("MFS" or the "Adviser"), is the Fund's investment adviser. Prior to 
September 1, 1993, Lifetime Advisers, Inc. ("LAI"), a Delaware corporation 
and a wholly owned subsidiary of MFS, was the investment adviser for the 
Fund. The Adviser is responsible for the management of the Fund's assets and 
the officers of the Trust are responsible for the Fund's operations. The 
Adviser manages the portfolio from day to day in accordance with the Fund's 
investment objective and policies. A majority of the Trustees are not 
affiliated with the Adviser. The selection of investments and the way they 
are managed depend on the conditions and trends in the economy and the 
financial marketplaces. The Trust also offers to buy back (redeem) shares of 
the Fund from Fund shareholders at any time at net asset value, less any 
applicable CDSC.

(1) Purchases of $1 million or more are not subject to an initial sales 
charge; however, a CDSC of 1% will be imposed on such purchases in the event 
of certain redemption transactions within 12 months following such purchases 
(see "Purchases" below). 

(2) For Class B shares, percentages are based on fees incurred during the 
fiscal year ended November 30, 1993. For Class A shares, which were initially 
offered on September 20, 1993, percentages are based on Class B expenses 
adjusted for Class A specific expenses. 

(3) The Fund has adopted a Distribution Plan for its Class A shares in 
accordance with Rule 12b-1 under the Investment Company Act of 1940, as 
amended (the "1940 Act"), which provides that it will pay distribution/ 
service fees aggregating up to (but not necessarily all of) 0.35% per annum 
of the average daily net assets attributable to the Class A shares (see 
"Distribution Plans"). After a substantial period of time distribution 
expenses paid under this Plan, together with the initial sales charge, may 
total more than the maximum sales charge that would have been permissible if 
imposed entirely as an initial sales charge.

(4) The Fund has adopted a Distribution Plan for its Class B shares in 
accordance with Rule 12b-1 under the 1940 Act, which provides that it will 
pay distribution/ service fees aggregating up to 1.00% per annum of the 
average net assets attributable to the Class B shares (see "Distribution 
Plans"). After a substantial period of time, distribution expenses paid under 
this Plan, together with any CDSC, may total more than the maximum sales 
charge that would have been permissible if imposed entirely as an initial 
sales charge. 

(5) Based on Class B expenses incurred during the last fiscal year except for

4. INVESTMENT OBJECTIVE AND POLICIES 
The Fund seeks to provide capital appreciation. Dividend income, if any, is a 
consideration incidental to the Fund's objective of capital appreciation. 

The Fund seeks to achieve its investment objective by varying the weighting 
of its portfolio among 15 equity sectors. The 15 sectors from among which the 
Fund chooses its investments are: autos and housing; consumer goods and 
services; defense and aerospace; energy; financial services; health care; 
heavy industry; leisure; machinery and equipment; precious metals and natural 
resources; retailing; technology; transportation; utilities; and foreign 
securities. (For a description of the scope of each of these industry 
sectors, see Appendix A to this Prospectus.) Certain sectors may overlap; for 
example, the defense and aerospace sector and the technology sector both 
include companies involved in the development of computer-related products. 
Therefore, securities of certain companies or industries may simultaneously 
be held in more than one industry sector. Generally, 

                                      4 
<PAGE> 
at least 90% of the assets of the Fund will be invested in securities in up 
to five such sectors or cash. Occasionally, the number of sectors may be 
increased if deemed appropriate by the Adviser due to the lack of desirable, 
concentrated investment opportunities at a particular time. 

In response to changes or anticipated changes in the general economy or 
within one or more particular industry sectors, the Fund may increase, 
decrease or eliminate entirely a particular sector's representation in the 
Fund's portfolio; similarly, the Fund may acquire securities of a sector not 
then represented in its portfolio. A sector or stock of a particular company 
will be added to or eliminated from the Fund's portfolio based upon such 
factors as such sector's or such company's economic cycle and sensitivity to 
interest rates. For example, as interest rates rise and the performance of 
interest-sensitive stocks declines, the Fund expects to remove such stocks 
from its portfolio. Any one sector or cash may comprise up to 50% of the 
Fund's portfolio. The Fund has registered as a "non-diversified" investment 
company so that more than 5% of the Fund's assets may be invested (subject to 
the tax limitations described below) in the securities of any one or more 
issuers. As a result of its non-diversified status, the Fund's shares may be 
more susceptible to adverse changes in the value of securities of a 
particular company than would be the shares of a diversified investment 
company. Similarly, due to the Fund's policy of generally concentrating in no 
more than five industry sectors at any one time, some of which may overlap, 
the value of the Fund's shares may be more susceptible to any single 
economic, political or regulatory occurrence than would be the shares of an 
investment company without a policy of concentration in particular industry 
sectors. 

While the Fund's policy is to invest primarily in common stocks, it may seek 
appreciation in other types of securities such as non-convertible and 
convertible bonds, convertible preferred stocks and warrants to purchase 
common stock, when relative values make such investments appear attractive 
either as individual issues or as types of securities in certain economic 
environments (see "Additional Information as to Investment Objective and 
Policies--Additional Risk Factors" and "--Risk Factors Regarding Lower Rated 
Securities" below). The non-convertible bonds invested in by the Fund may 
include (i) obligations issued or guaranteed by the U.S. Treasury or U.S. 
Government agencies, authorities or instrumentalities, and (ii) obligations 
of the U.S. Treasury that have been issued without interest coupons or 
stripped of their unmatured interest coupons, interest coupons that have been 
stripped from such debt obligations, and receipts and certificates for such 
stripped debt obligations and stripped coupons. U.S. Government securities 
also include interests in trusts or other entities representing interests in 
obligations that are issued or guaranteed by the U.S. Government, its 
agencies, authorities or instrumentalities. The Fund may invest in foreign 
securities and hold foreign currency (see "Additional Risk Factors" below). 
The Fund may also enter into forward foreign currency exchange contracts for 
the purchase or sale of foreign currency for hedging purposes and non-hedging 
purposes, including transactions entered into for the purpose of profiting 
from anticipated changes in foreign currency exchange rates, as well as 
options on foreign currencies (see "Investment Techniques--Forward Contracts 
on Foreign Currency" and "--Options on Foreign Currencies" below). 

The Fund may invest in corporate asset-backed securities (see "Investment 
Techniques--Corporate Asset-Backed Securities" below). The Fund may write 
covered call and put options and purchase call and put options on securities 
and stock indexes in an effort to increase current income and for hedging 
purposes (see "Investment Techniques--Options" below). The Fund may also 
purchase and sell stock index and interest rate futures contracts and may 
write and purchase options thereon for hedging purposes and for non-hedging 
purposes, subject to applicable law (see "Investment Techniques--Futures 
Contracts and Options on Futures Contracts" below). In addition, the Fund may 
purchase portfolio securities on a "when-issued" or on a "forward delivery" 
basis (see "Investment Techniques--When-Issued Securities" below). 

Subject to tax requirements, portfolio changes are made without regard to the 
length of time a security has been held, or whether a sale would result in a 
profit or loss. 

Additional Information as to Investment Objective and Policies 

Fixed Income Securities--When and if available, the Fund may purchase fixed 
income securities at a discount from face value. However, the Fund does not 
intend to hold such securities to maturity for the purpose of achieving 
potential capital gains, unless current yields on these securities remain 
attractive. 

                                      5 
<PAGE> 

Risk Factors Regarding Lower Rated Securities--The Fund may invest to a 
limited extent in lower rated fixed income securities or comparable unrated 
securities. Investments in such securities while generally providing greater 
income and opportunity for gain than investments in higher rated securities, 
usually entail greater risk of principal and income (including the 
possibility of default or bankruptcy of the issuers of such securities), and 
involve greater volatility of price (especially during periods of economic 
uncertainty or change) than investments in higher rated securities and 
because yields may vary over time, no specified level of income can ever be 
assured. In particular, securities rated lower than Baa by Moody's Investors 
Service, Inc. ("Moody's") or BBB by Standard & Poor's Ratings Group ("S&P") 
or comparable unrated securities (commonly known as "junk bonds") are 
considered speculative. For a description of these ratings, see Appendix B to 
this Prospectus. 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. During certain periods, the higher 
yields on the Fund's lower rated high yielding fixed income securities are 
paid primarily because of the increased risk of loss of principal and income, 
arising from such factors as the heightened possibility of default or 
bankruptcy of the issuers of such securities. Due to the fixed income 
payments of these securities, the Fund may continue to earn the same level of 
interest income while its net asset value declines due to portfolio losses, 
which could result in an increase in the Fund's yield despite the actual loss 
of principal. The prices for these securities may be affected by legislative 
and regulatory developments. For example, federal rules require that savings 
and loan associations gradually reduce their holdings of high-yield 
securities. An effect of such legislation may be to depress the prices of 
outstanding lower rated high yielding fixed income securities. Changes in the 
value of securities subsequent to their acquisition will not affect cash 
income or yield to maturity to the Fund but will be reflected in the net 
asset value of shares of the Fund. 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 at their fair value to 
meet redemption requests or to respond to changes in the market. No minimum 
rating standard is required by the Fund. To the extent the Fund invests in 
these lower rated fixed income securities, the achievement of its investment 
objective may be more dependent on the Adviser's own credit analysis than in 
the case of fund investing in higher quality bonds. While the Adviser may 
refer to ratings issued by established credit rating agencies, it is not a 
policy of the Fund to relay exclusively on ratings issued by these agencies, 
but rather to supplement such ratings with the Adviser's own independent and 
ongoing review of credit quality. 

The Fund may also invest in fixed income securities rated Baa by Moody's or 
BBB by S&P and comparable unrated securities. These securities, while 
normally exhibiting adequate protection parameters, may have speculative 
characteristics and changes in economic conditions and other circumstances 
are more likely to lead to a weakened capacity to make principal and interest 
payments than in the case of higher grade fixed income securities. 

Additional Risk Factors--The net asset value of the shares of an open-end 
investment company which may invest to a limited extent in fixed income 
securities changes as the general levels of interest rates fluctuate. When 
interest rates decline, the value of a fixed income portfolio can be expected 
to rise. Conversely, when interest rates rise, the value of a fixed income 
portfolio can be expected to decline. 

Although changes in the value of securities subsequent to their acquisition 
are reflected in the net asset value of shares of the Fund, such changes will 
not affect the income received by the Fund from such securities. However, the 
dividends paid by the Fund, if any, will increase or decrease in relation to 
the income received by the Fund from its investments, which would in any case 
be reduced by the Fund's expenses before it is distributed to shareholders. 

                                      6 
<PAGE> 

In addition, the use of options, futures contracts, options on futures 
contracts, forward contracts and options on foreign currencies (see 
"Investment Techniques" below) may result in the loss of principal, 
particularly where such instruments are traded for other than hedging 
purposes (e.g., to enhance current yield). 

The portfolio of the Fund is aggressively managed and, therefore, the value 
of its shares is subject to greater fluctuation and investments in its shares 
involve the assumption of a higher degree of risk than would be the case with 
an investment in a conservative equity fund or a growth fund investing 
entirely in proven growth equities. 

The Fund may also invest in foreign securities, which may be traded on 
foreign exchanges. The Fund may invest up to 50% (and expects generally to 
invest between 15% and 35%) of its total assets in foreign securities (not 
including American Depositary Receipts). Investing in foreign securities or 
on foreign exchanges may present a greater degree of risk than investing in 
domestic issuers. These risks include changes in currency rates, exchange 
control regulations, governmental administration, economic or monetary policy 
(in this country or abroad), war or expropriation. In particular, the dollar 
value of portfolio securities of non-U.S. issuers fluctuates with changes in 
market and economic conditions abroad and with changes in relative currency 
values (when the value of the dollar increases as compared to a foreign 
currency, the dollar value of a foreign-denominated security decreases, and 
vice versa). 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 confiscatory taxation and potential 
difficulties in enforcing contractual obligations and could be subject to 
extended settlement periods. Therefore, an investment in shares of the Fund 
may be subject to a greater degree of risk than investments in other 
investment companies which invest exclusively in domestic securities. 

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. In that event, the Fund may promptly convert such currencies 
into dollars at the then current exchange rate. Under certain circumstances, 
however, 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. 

In addition, the Fund may be required to receive delivery of the foreign 
currency underlying forward foreign currency contracts it has entered into. 
This could occur, for example, if an option written by the Fund is exercised 
or the Fund is unable to close out a forward contract it has entered into. 
The Fund may also hold foreign currency in anticipation of purchasing foreign 
securities. The Fund may also elect to take delivery of the currencies 
underlying options or forward contracts if, in the judgment of the Adviser, 
it is in the best interest of the Fund to do so. In such instances as well, 
the Fund may promptly convert the foreign currencies to dollars at the then 
current exchange rate, or 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, it also exposes the Fund 
to risk of loss if such 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 of securities, and could reduce the 
dollar value of interest or dividend payments received. In addition, the 
holding of currencies could adversely affect the Fund's profit or loss on 
currency options or forward contracts, as well as its hedging strategies. 

Costs may be incurred in connection with conversions between various 
currencies. Foreign brokerage commissions are generally higher than in the 
United States and foreign securities markets may be less liquid, more 
volatile and less subject to governmental supervision than in the United 
States. See the Statement of Additional Information for further discussion of 
foreign securities and the holding of foreign currency as well as the 
associated risks. 

The Fund may also invest in American Depositary Receipts ("ADRs") which are 
certificates issued by a U.S. depository (usually a bank) and represent a 
specified quantity of shares of an underlying non-U.S. stock on deposit with 
a custodian bank as col- 

                                      7 
<PAGE> 

lateral. Although ADRs are issued by a U.S. depository, they are subject to 
many of the risks of foreign securities such as exchange rates and more 
limited information about foreign issuers. 

The Fund has registered as a "non-diversified" investment company. As a 
result, the Fund is limited as to the percentage of its assets that may be 
invested in the securities of any one issuer only by its own investment 
restrictions and the diversification requirements of the Internal Revenue 
Code of 1986, as amended (the "Code"). U.S. Government securities are not 
subject to any investment limitation. Since the Fund may invest a relatively 
high percentage of its assets in the obligations of a limited number of 
issuers, the Fund may be more susceptible to any single economic, political 
or regulatory occurrence. 

Given the above average investment risk inherent in the Fund, investment in 
shares of the Fund should not be considered a complete investment program and 
may not be appropriate for all investors. 

Short-Term Investments for Defensive Purposes--During periods of unusual 
market conditions when the Adviser believes that investing for 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 or 
cash equivalents including, but not limited to, obligations of banks 
(including certificates of deposit bankers' acceptances and repurchase 
agreements) with assets of $1 billion or more, commercial paper, short-term 
notes, obligations issued or guaranteed by the U.S. Government or any of its 
agencies, authorities or instrumentalities and related repurchase agreements. 
See Appendix C to this Prospectus for a description of certain short-term 
obligations. 

The investment objective and policies discussed above may be changed without 
shareholder approval. 

5. INVESTMENT TECHNIQUES 
Lending of Securities: The Fund may make loans of its portfolio securities. 
Such loans will usually be made only to member banks of the Federal Reserve 
System and member firms (and subsidiaries thereof) of the New York Stock 
Exchange and would be required to be secured continuously by collateral in 
cash, cash equivalents or U.S. Government Securities maintained on a current 
basis at an amount at least equal to the market value of the securities 
loaned. The Fund would continue to collect the equivalent of the dividends or 
interest on the securities loaned and would also receive either interest 
(through investment of cash collateral) or a fee (if the collateral is U S. 
Government Securities). 

Repurchase Agreements: The Fund may enter into repurchase agreements in order 
to earn additional income on available cash or as a temporary defensive 
measure. Under a repurchase agreement, the Fund acquires securities subject 
to the seller's agreement to repurchase at a specified time and price. If the 
seller becomes subject to a proceeding under the bankruptcy laws or its 
assets are otherwise subject to a stay order, the Fund's right to liquidate 
the securities may be restricted (during which time the value of the 
securities could decline). As discussed in the Statement of Additional 
Information, the Fund has adopted certain procedures which are intended to 
minimize any such risk. 

When-Issued Securities: In order to help ensure the availability of suitable 
securities for its portfolio, the Fund may purchase securities on a "when- 
issued" or on a "forward delivery" basis, which means that the obligations 
will be delivered to the Fund at a future date usually beyond customary 
settlement time. It is expected that, under normal circumstances, the Fund 
will take delivery of such securities. In general, the Fund does not pay for 
the securities until received and does not start earning interest on the 
obligations until the contractual settlement date. While awaiting delivery of 
the obligations purchased on such bases, the Fund will establish a segregated 
account consisting of cash, short-term money market instruments or high 
quality debt securities equal to the amount of the commitments to purchase 
"when-issued" securities. See the Statement of Additional Information. 

Restricted Securities--The Fund may also purchase securities that are not 
registered under the Securities Act of 1933 (the "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"). The Trust's Board of Trustees determines, based upon a 
continuing review of the trading markets for a specific Rule 144A security, 
whether such security is illiquid and thus subject to the Fund's limitation 

                                      8 
<PAGE> 

on investing not more than 15% of its net assets in illiquid investments, or 
liquid and thus not subject to such limitation. The Board of Trustees has 
adopted guidelines and delegated to MFS the daily function of determining and 
monitoring the liquidity of Rule 144A securities. The Board, however, will 
retain sufficient oversight and be ultimately responsible for the 
determinations. The Board will carefully monitor the Fund's investments in 
Rule 144A securities, focusing on such important factors, among others, as 
valuation, liquidity and availability of information. This investment 
practice could have the effect of increasing the level of illiquidity in a 
Fund to the extent that qualified institutional buyers become for a time 
uninterested in purchasing Rule 144A securities held in the Fund's portfolio. 
Subject to the Fund's 15% 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. 

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 or 
automobile loan receivables, representing the obligations of a number of 
different parties. Corporate asset-backed 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. See 
the Statement of Additional Information for further information on these 
securities. 

Transactions in Options, Futures and Forward Contracts: The Fund may enter 
into transactions in options, futures and forward contracts on a variety of 
instruments and indexes, in order to protect against declines in the value of 
portfolio securities or increases in the cost of securities or other assets 
to be acquired and, subject to applicable law, to increase the Fund's gross 
income. The types of instruments to be purchased and sold by the Fund are 
described in the Statement of Additional Information, which should be read in 
conjunction with the following section. In addition, the Statement of 
Additional Information contains a further discussion of the nature of the 
transactions which may be entered into and the risks associated therewith. 

Options 
Options on Securities--The Fund may write (sell) covered call and put options 
and purchase call and put options on securities. The Fund will write options 
on securities for the purpose of increasing its return on such securities 
and/or to protect the values of its portfolio. In particular, where the Fund 
writes an option which expires unexercised or is closed out by the Fund at a 
profit, it will retain the premium paid for the option which will increase 
its gross income and will offset in part the reduced value of the portfolio 
security underlying the option, or the increased cost of portfolio securities 
to be acquired. In contrast, however, if the price of the underlying security 
moves adversely to the Fund's position, the option may be exercised and the 
Fund will be required to purchase or sell the underlying security at a 
disadvantageous price, which may only be partially offset by the amount of 
the premium. The Fund may also write combinations of put and call options on 
the same security, known as "straddles." Such transactions can generate 
additional premium income but also present increased risk. 

By writing a call option on a security, the Fund limits its opportunity to 
profit from any increase in the market value of the underlying security, 
since the holder will usually exercise the call option when the market value 
of the underlying security exceeds the exercise price of the call. However, 
the Fund retains the risk of depreciation in value of securities on which it 
has written call options. 

The Fund may also purchase put or call options in anticipation of market 
fluctuations which may adversely affect the value of its portfolio or the 
prices of securities that the Fund wants to purchase at a later date. In the 
event that the expected market fluctuations occur, the Fund may be able to 
offset the resulting adverse effect on its portfolio, in whole or in part, 
through the options purchased. The premium paid for a put or call option plus 
any transaction costs will reduce the benefit, if any, realized by the Fund 
upon exercise or liquidation of the option, and, unless the price of the 
underlying security changes sufficiently, the option may expire without value 
to the Fund. 

                                      9 
<PAGE> 

In certain instances, the Fund may enter into options on Treasury securities 
which may be referred to as "reset" options or "adjustable strike" options. 
These options provide for periodic adjustment of the strike price and may 
also provide for the periodic adjustment of the premium during the term of 
the option. 

Options on Stock Indices--The Fund may write (sell) covered call and put 
options and purchase call and put options on stock indices. The Fund may 
write options on stock indices for the purpose of increasing its gross income 
and to protect its portfolio against declines in the value of securities it 
owns or increases in the value of securities to be acquired. When the Fund 
writes an option on a stock index, and the value of the index moves adversely 
to the holder's position, the option will not be exercised, and the Fund will 
either close out the option at a profit or allow it to expire unexercised. 
The Fund will thereby retain the amount of the premium, less related 
transaction costs, which will increase its gross income and offset part of 
the reduced value of portfolio securities or the increased cost of securities 
to be acquired. Such transactions, however, will constitute only partial 
hedges against adverse price fluctuations, since any such fluctuations will 
be offset only to the extent of the premium received by the Fund for the 
writing of the option, less related transaction costs. In addition, if the 
value of an underlying index moves adversely to the Fund's option position, 
the option may be exercised, and the Fund will experience a loss which may 
only be partially offset by the amount of the premium received. 

The Fund may also purchase put or call options on stock indices in order, 
respectively, to hedge its investments against a decline in value or to 
attempt to reduce the risk of missing a market or industry segment advance. 
The Fund's possible loss in either case will be limited to the premium paid 
for the option, plus related transaction costs. 

Futures Contracts and Options on Futures Contracts 
Futures Contracts--The Fund may enter into interest rate futures contracts, 
stock index futures contracts and foreign currency futures contracts. (Unless 
otherwise specified, interest rate futures contracts, futures contracts on 
indices and foreign currency futures contracts are collectively referred to 
as "Futures Contracts.") The Fund will utilize Futures Contracts for hedging 
and non-hedging purposes, subject to applicable law. Purchases or sales of 
stock index futures contracts for hedging purposes are used to attempt to 
protect the Fund's current or intended stock investments from broad 
fluctuations in stock prices, and foreign currency futures contracts are 
purchased or sold to attempt to hedge against the effects of exchange rate 
charges on a Fund's current or intended investments in fixed income or 
foreign securities. In the event that an anticipated decrease in the value of 
portfolio securities occurs as a result of a general stock market decline, a 
general increase in interest rates or a decline in the dollar value of 
foreign currencies in which portfolio securities are denominated, the adverse 
effects of such changes may be offset, in whole or part, by gains on the sale 
of Futures Contracts. Conversely, the increased cost of portfolio securities 
to be acquired, caused by a general rise in the stock market, a general 
decline in interest rates or a rise in the dollar value of foreign 
currencies, may be offset, in whole or part, by gains on Futures Contracts 
purchased by the Fund. The Fund will incur brokerage fees when it purchases 
and sells Futures Contracts, and it will be required to make and maintain 
margin deposits. 

Options on Futures Contracts--The Fund may purchase and write options to buy 
or sell interest rate futures contracts and options on stock index futures 
contracts. (Unless otherwise specified, options on interest rate futures 
contracts and options on stock index futures contracts are collectively 
referred to as "Options on Futures Contracts.") Such investment strategies 
will be used for hedging and non-hedging purposes, subject to applicable law. 
Put and call Options on Futures Contracts may be traded by the Fund in order 
to protect against declines in the values of portfolio securities or against 
increases in the cost of securities to be acquired. Purchases of Options on 
Futures Contracts may present less risk in hedging the portfolios of the Fund 
than the purchase or sale of the underlying Futures Contracts since the 
potential loss is limited to the amount of the premium plus related 
transaction costs. The writing of such options, however, does not present 
less risk than the trading of Futures Contracts and will constitute only a 
partial hedge, up to the amount of the premium received. In addition, if an 
option is exercised, the Fund may suffer a loss on the transaction. 

Forward Contracts on Foreign Currency--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 of the contract (a "Forward Contract"). The Fund will enter into 
Forward Contracts 

                                      10 
<PAGE> 

for hedging and non-hedging purposes including transactions entered into for 
the purpose of profiting from anticipated changes in foreign currency 
exchange rates. Transactions in Forward Contracts entered into for hedging 
purposes may include forward purchases or sales of foreign currencies for the 
purpose of protecting the dollar value of securities denominated in a foreign 
currency or protecting the dollar equivalent of interest or dividends to be 
paid on such securities. The Fund may also enter into Forward Contracts for 
"cross hedging" purposes, e.g., the purchase or sale of a Forward Contract on 
one type of currency as a hedge against adverse fluctuations in the value of 
a second type of currency. By entering into such transactions, however, the 
Fund may be required to forgo the benefits of advantageous changes in 
exchange rates. The Fund may also enter into transactions in Forward 
Contracts for other than hedging purposes. For example, if the Adviser 
believes that the value of a particular foreign currency will increase or 
decrease relative to the value of the U.S. dollar, the Fund may purchase or 
sell such currency, respectively, through a Forward Contract. If the expected 
changes in the value of the currency occur, the Fund will realize profits 
which will increase its gross income. Such transactions, however, may be 
considered speculative and could involve significant risk of loss, as set 
forth below. The Fund has established procedures consistent with statements 
of the Securities and Exchange Commission (the "SEC") and its staff regarding 
the use of Forward Contracts by registered investment companies, which 
requires use of segregated assets or "cover" in connection with the purchase 
and sale of such contracts. 

Forward Contracts are traded over-the-counter, and not on organized 
commodities or securities exchanges. As a result, such contracts operate in a 
manner distinct from exchange-traded instruments, and their use involves 
certain risks beyond those associated with transactions in the Futures and 
Options contracts described above. 

Options on Foreign Currencies: The Fund may purchase and write put and call 
options on foreign currencies for the purpose of protecting against declines 
in the dollar value of portfolio securities, and against increases in the 
dollar cost of securities to be acquired. As in the case of other types of 
options, however, the writing of an option on foreign currency will 
constitute only a partial hedge, up to the amount of the premium received, 
and the Fund could be required to purchase or sell foreign currencies at 
disadvantageous exchange rates, thereby incurring losses. The purchase of an 
option on foreign currency may constitute an effective hedge against 
fluctuations in exchange rates although, in the event of rate movements 
adverse to the Fund's position, it may forfeit the entire amount of the 
premium plus related transaction costs. As in the case of Forward Contracts, 
certain options on foreign currencies are traded over-the-counter and involve 
risks which may not be present in the case of exchange-traded instruments. 

Risks of Transactions in Options, Futures Contracts and Forward 
Contracts: Although the Fund will enter into certain transactions in Futures 
Contracts, Options on Futures Contracts, Forward Contracts and options for 
hedging purposes, such transactions do involve certain risks. For example, a 
lack of correlation between the index or instrument underlying an option, 
Futures Contract of Forward Contract and the assets being hedged, or 
unexpected adverse price movements, could render the Fund's hedging strategy 
unsuccessful and could result in losses. "Cross hedging" transactions may 
involve greater correlation risks. In addition, there can be no assurance 
that a liquid secondary market will exist for any contract purchased or sold, 
and the Fund may be required to maintain a position until exercise or 
expiration, which could result in losses. As noted, the Fund may also enter 
into transactions in such instruments (except for options on foreign 
currencies) for other than hedging purposes (subject to applicable law), 
including speculative transactions, which involve greater risk. In 
particular, in entering into such transactions, the Fund may experience 
losses which are not offset by gains on other portfolio positions, thereby 
reducing its gross income. In addition, the markets for such instruments may 
be extremely volatile from time to time, as discussed in the Statement of 
Additional Information, which could increase the risks incurred by the Fund 
in entering into such transactions. 

Transactions in options may be entered into on U.S. exchanges regulated by 
the SEC, in the over-the-counter market and on foreign exchanges, while 
Forward Contracts may be entered into only in the over-the-counter market. 
Futures Contracts and Options on Futures Contracts may be entered into on 
U.S. exchanges regulated by the Commodity Futures Trading Commission (the 
"CFTC") and on foreign exchanges. The securities underlying options and 
Futures Contracts traded by the Fund may include domestic as well as foreign 
securities. Investors should recognize that transactions involving foreign 
securities or foreign currencies, and transactions entered into in foreign 
countries, may involve considerations and risks not typically associated with 
investing in U.S. markets. 

                                      11 
<PAGE> 

Transactions in options, Futures Contracts, Options on Futures Contracts and 
Forward Contracts entered into for non-hedging purposes involve greater risk 
and could result in losses which are not offset by gains on other portfolio 
assets. For example, the Fund may sell Futures Contracts on an index of 
securities in order to profit from any anticipated decline in the value of 
the securities comprising the underlying index. In such instances, any losses 
on the Futures transaction will not be offset by gains on any portfolio 
securities comprising such index, as might occur in connection with a hedging 
transaction. The risks related to transactions in options, Futures Contracts, 
Options on Futures Contracts and Forward Contracts entered into by the Fund 
are set forth in greater detail in the Statement of Additional Information, 
which should be reviewed in conjunction with the foregoing discussion. 

Portfolio Trading 
The primary consideration in placing portfolio security transactions with 
broker-dealers for execution is to obtain, and maintain the availability of, 
execution at the most favorable prices and in the most effective manner 
possible. Consistent with the foregoing primary consideration, the Rules of 
Fair Practice of the National Association of Securities Dealers, Inc. (the 
"NASD") and such other policies as the Trustees may determine, the Adviser 
may consider sales of shares of the Fund and of other investment company 
clients of MFS Financial Services, Inc. ("FSI"), the Fund's distributor, as a 
factor in the selection of broker-dealers to execute the Fund's portfolio 
transactions. For a further discussion of portfolio trading, see the 
Statement of Additional Information. 

Since shares of the Fund represent an investment in securities with 
fluctuating market prices, shareholders should understand that the value of 
their shares will vary as the aggregate value of the Fund's portfolio 
securities increases or decreases. Moreover, any dividends the Fund pays will 
increase or decrease in relation to the income received from its investments. 

The Statement of Additional Information includes a discussion of other 
investment policies and a listing of specific investment restrictions which 
govern the Fund's investment policies. The specific investment restrictions 
listed in the Statement of Additional Information may not be changed without 
shareholder approval (see "Investment Restrictions" in the Statement of 
Additional Information). The Fund's investment limitations, policies and 
rating standards 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. 

6. MANAGEMENT OF THE FUND 

Investment Adviser--MFS manages the Fund pursuant to an Investment Advisory 
Agreement dated September 1, 1993 (the "Advisory Agreement"). The Adviser 
provides the Fund with overall investment advisory and administrative 
services, as well as general office facilities. Kenneth J. Enright, a Vice 
President of the Adviser, has been the Fund's portfolio manager since 
September 1, 1993. Mr. Enright has been employed by the Adviser since 1986. 
Subject to such policies as the Trustees may determine, the Adviser makes 
investment decisions for the Fund. For its services and facilities, the 
Adviser receives a management fee, computed and paid monthly, in an amount 
equal to 0.75% of the Fund's average daily net assets for its then-current 
fiscal year. 

For the Fund's fiscal year ended November 30, 1993 the Fund's current 
investment adviser, MFS, together with the Fund's former investment adviser, 
Lifetime Advisers, Inc. (a wholly owned subsidiary of MFS) received 
management fees under the Fund's Advisory Agreements of $2,065,624. 

MFS also serves as investment adviser to each of the other funds in the MFS 
Family of Funds (the "MFS Funds") and to MFS(R) Municipal Income Trust, MFS 
Multimarket Income Trust, MFS Government Markets Income Trust, MFS 
Intermediate Income Trust, MFS Charter Income Trust, MFS Special Value Trust, 
MFS Union Standard Trust, MFS Institutional Trust, MFS/Sun Life Series Trust, 
Sun Growth Variable Annuity Fund, Inc. and seven variable accounts, each of 
which is a registered investment company established by Sun Life Assurance 
Company of Canada (U.S.) ("Sun Life of Canada (U.S.)") in connection with the 
sale of Compass-2 and Compass-3 combination fixed/variable annuity contracts. 
The MFS Asset Management Group, a division of the Adviser, provides 
investment advice to substantial private clients.

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 in the United States, Massachusetts 
Investors Trust. Net assets under the management of the MFS organization were 
approximately $34.9 billion on behalf of approximately 1.4 million investor 
accounts as of February 28, 1994. As of such date, the MFS organization 
managed approximately $9.9 billion of assets invested in equity securities 
and approximately $21.5 billion of assets invested in fixed income 
securities. Approximately $4.3 billion of the assets managed by MFS are 
invested in securities of foreign issuers and non-U.S. dollar denominated 
securities of U.S. issuers. MFS is a subsidiary of Sun Life of Canada (U.S.), 
which in turn is a subsidiary of Sun Life Assurance Company of Canada ("Sun 
Life"). The Directors of MFS are A. Keith Brodkin, Jeffrey L. Shames, Arnold 
D. Scott, John D. McNeil and John R. Gardner. Mr. Brodkin is the Chairman, 
Mr. Shames is the President and Mr. Scott is the Secretary and a Senior 
Executive Vice President of MFS. Messrs. McNeil and Gardner are the Chairman 
and President, respectively, of Sun Life. Sun Life, a mutual life insurance

7. INFORMATION CONCERNING SHARES OF THE FUND 

Purchases 
Shares of the Fund may be purchased at the public offering price through any 
securities dealer, certain banks and other financial institutions having 
selling agreements with FSI. Non-securities dealer financial institutions 
will receive transaction fees that are the same as commission fees to 
dealers. Securities dealers and other financial institutions may also charge 
their customers fees relating to investments in the Fund. 

The Fund offers two classes of shares which bear sales charges and 
distribution fees in different forms and amounts: 

Class A shares. Class A shares are offered at net asset value plus an initial 
sales charge (or CDSC in the case of certain purchases of $1 million or more) 
as follows:

<FN>
 *Because of rounding in the calculation of offering price, actual sales charges may be 
  more or less than those calculated using the percentages above. 
**A CDSC may apply in certain circumstances. FSI will pay a commission on purchases of 
  $1 million or more. 
</FN>
</TABLE>

No sales charge is payable at the time of purchase of Class A shares on 
investments of $1 million or more. However, a CDSC shall be imposed on such 
investments in the event of a share redemption within 12 months following the 
share purchase, at the rate of 1% on the lesser of the value of the shares 
redeemed (exclusive of reinvested dividends and capital gain distributions) 
or the total cost of such shares. 

                                      13 
<PAGE> 

In determining whether a CDSC on such Class A shares is payable, and, if so, 
the amount of the charge, it is assumed that shares not subject to the CDSC 
are the first redeemed followed by other shares held for the longest period 
of time. All investments made during a calendar month, regardless of when 
during the month the investment occurred, will age one month on the last day 
of the month and each subsequent month. Except as noted below, the CDSC on 
Class A shares will be waived in the case of: (i) exchanges (except that if 
the shares acquired by exchange were then redeemed within 12 months of the 
initial purchase (other than in connection with subsequent exchanges to other 
MFS Funds), the charge would not be waived); (ii) distributions to 
participants from a retirement plan qualified under Section 401(a) of the 
Internal Revenue Code of 1986, as amended (the "Code") (a "Retirement Plan"), 
due to: (a) a loan from the plan (repayments of loans, however, will 
constitute new sales for purposes of assessing the CDSC; (b) "financial 
hardship" of the participant in the plan, as that term is defined in Treasury 
Regulation Section 1.401(k)-1(d)(2), as amended from time to time; or (c) the 
death of a participant in such a plan; (iii) distributions from a 403(b) plan 
or an Individual Retirement Account ("IRA"), due to death, disability, or 
attainment of age 59-1/2; (iv) tax-free returns of excess contributions to an 
IRA; (v) distributions by other employee benefit plans to pay benefits; and 
(vi) certain involuntary redemptions and redemptions in connection with 
certain automatic withdrawals from a qualified retirement plan. The CDSC on 
Class A shares will not be waived, however, if the retirement plan withdraws 
from the Fund except if that retirement plan has invested its assets in Class 
A shares of one or more of the MFS Funds for more than 10 years from the 
later to occur of (i) January 1, 1993 or (ii) the date such retirement plan 
first invests its assets in Class A shares of one or more of the MFS Funds, 
the CDSC on Class A shares will be waived in the case of a redemption of all 
of the Retirement Plan's shares (including shares of any other class) in all 
MFS Funds (i.e., all the assets of the Retirement Plan invested in the MFS 
Funds are withdrawn), unless, immediately prior to the redemption, the 
aggregate amount invested by the Retirement Plan in Class A shares of the MFS 
Funds (excluding the reinvestment of distributions) during the prior four 
year period equals 50% or more of the total value of the Retirement Plan's 
assets in the MFS Funds, in which case the CDSC will not be waived. Any 
applicable CDSC will be deferred upon an exchange of Class A shares of the 
Fund for units of participation of the MFS Fixed Fund (a bank collective 
investment fund) (the "Units"), and the CDSC will be deducted from the 
redemption proceeds when such Units are subsequently redeemed (assuming the 
CDSC is then payable). No CDSC will be assessed upon an exchange of Units for 
Class A shares of the Fund. For purposes of calculating the CDSC payable upon 
redemption of Class A shares of the Fund or Units acquired pursuant to one or 
more exchanges, the period during which the Units are held will be aggregated 
with the period during which the Class A shares are held. The applicability 
of the CDSC will be unaffected by transfers of registration. FSI shall 
receive all CDSCs. 

FSI allows discounts to dealers (which are alike for all dealers) from the 
applicable public offering price, as shown in the table above. In the case of 
the maximum sales charge, the dealer retains 5% and FSI retains approximately 
3/4 of 1% of the public offering price. The sales charge may vary depending 
on the number of shares of the Fund as well as certain MFS Funds and other 
Funds owned or being purchased, the existence of an agreement to purchase 
additional shares during a 13-month period (or 36-month period for purchases 
of $1 million or more) or other special purchase programs. A description of 
the Right of Accumulation, Letter of Intent and Group Purchases privileges by 
which the sales charge may be reduced is set forth in the Statement of 
Additional Information. In addition, FSI, will pay a commission to dealers 
who initiate and are responsible for purchases of $1 million or more as 
follows: 1.00% on sales up to $5 million, plus 0.25% on the amount in excess 
of $5 million. Purchases of $1 million or more for each shareholder account 
will be aggregated over a 12-month period (commencing from the date of the 
first such purchase) for purposes of determining the level of commissions to 
be paid during that period with respect to such account. 

Class A shares of the Fund may be sold at their net asset value to the 
officers of the Trust, to any of the subsidiary companies of Sun Life, to 
eligible Directors, officers, employees (including retired employees) and 
agents of MFS, Sun Life or any of their subsidiary companies, to any trust, 
pension, profit-sharing or any other benefit plan for such persons, to any 
trustees and retired trustees of any investment company for which FSI serves 
as distributor or principal underwriter, and to certain family members of 
such individuals and their spouses, provided the shares will not be resold 
except to the Fund. Class A shares of the Fund may be sold at net asset value 
to any employee, partner, officer or trustee of any sub-adviser to any MFS 
Fund and to certain family members of such individuals and their spouses, or 
to any trust, pension, profit-sharing or other retirement 

                                      14 
<PAGE> 
plan for the sole benefit of such employee or representative, provided such 
shares will not be resold except to the Fund. Class A shares of the Fund may 
also be sold at their net asset value to any employee or registered 
representative of any dealer or other financial institution which has a sales 
agreement with FSI or its affiliates, to certain family members of such 
employee or representative and their spouses, or to any trust, pension, 
profit-sharing or other retirement plan for the sole benefit of such employee 
or representative, as well as to clients of the MFS Asset Management Group. 
Class A shares of the Fund also may be sold at net asset value, subject to 
appropriate documentation, through a dealer where the amount invested 
represents redemption proceeds from a registered open-end management 
investment company not distributed or managed by FSI or its affiliates, if 
such redemption has occurred no more than 60 days prior to the purchase of 
Class A shares of the Fund and the shareholder either (i) paid an initial 
sales charge or (ii) was at some time subject to, but did not actually pay, a 
deferred sales charge with respect to the redemption proceeds. Class A shares 
of the Fund may also be sold at net asset value where the amount invested 
represents redemption proceeds from the MFS Fixed Fund. In addition, Class A 
shares may be sold at their net asset value in connection with the 
acquisition or liquidation of the assets of other investment companies or 
personal holding companies. Insurance company separate accounts may also 
purchase Class A shares of the Fund at their net asset value. Class A shares 
of the Fund may also be purchased at their net asset value by retirement 
plans where third party administrators of such plans have entered into 
certain arrangements with FSI or its affiliates provided that no commission 
is paid to dealers. Class A shares of the Fund may also be purchased at net 
asset value where the purchase is in an amount of $3 million or more and 
where the dealer and FSI enter into an agreement in which the dealer agrees 
to return any commission paid to it on the sale (or on a pro rata portion 
thereof) as described above if the shareholder redeems his or her shares 
within a year of purchase (shareholders who purchase shares at net asset 
value pursuant to these conditions are called "$3 Million Shareholders"). 

Class A shares of the Fund may be purchased at net asset value by retirement 
plans qualified under section 401(a) or 403(b) of the Code which are subject 
to the Employee Retirement Income Security Act of 1974, as amended, as 
follows: 

  (i) the retirement plan and/or the sponsoring organization must subscribe 
to the MFS FUNDamental 401(k) Plan((SM)) or another similar Section 401(a) or 
403(b) recordkeeping program made available by MFS Service Center, Inc.; 

  (ii) either (a) the sponsoring organization must have at least 25 employees 
or (b) the aggregate purchases by the retirement plan of Class A shares of 
the MFS Funds must be in an amount of at least $250,000 within a reasonable 
period of time, as determined by FSI in its sole discretion; and 

  (iii) a CDSC of 1% will be imposed on such purchases in the event of 
certain redemption transactions within 12 months following such purchases. 

Dealers who initiate and are responsible for purchases of Class A shares of 
the Fund in this manner will be paid a commission by FSI, as follows: 1.00% 
on sales up to $5 million, plus 0.25% on the amount in excess of $5 million; 
provided, however, that FSI may pay a commission, on sales in excess of $5 
million to certain retirement plans, of 1.00% to certain dealers which, at 
FSI's invitation, enter into an agreement with FSI in which the dealer agrees 
to return any commission paid to it on the sale (or on a pro rata portion 
thereof) if the shareholder redeems his or her shares within a period of time 
after purchase as specified by FSI. Purchases of $1 million or more for each 
shareholder account will be aggregated over a 12-month period (commencing 
from the date of the first such purchase) for purposes of determining the 
level of commissions to be paid during that period with respect to such 
account. Class A shares of the Fund may be purchased at net asset value 
through certain broker-dealers and other financial institutions which have 
entered into an agreement with FSI, which includes a requirement that such 
shares be sold for the benefit of clients participating in a "wrap account" 
or a similar program under which such clients pay a fee to such broker-dealer 
or other financial institution. Furthermore, Class A shares of the Fund may 
be sold at net asset value through the automatic reinvestment of 
distributions of dividends and capital gains of other MFS Funds pursuant to 
the Distribution Investment Program (see "Shareholder Services" in the 
Statement of Additional Information).

No CDSC is paid upon an exchange of shares. For purposes of calculating the 
CDSC upon redemption of shares acquired in an exchange, the purchase of 
shares acquired in one or more exchanges is deemed to have occurred at the 
time of the original purchase of the exchanged shares. See "Redemptions and 
Repurchases--Contingent Deferred Sales Charge" for further discussion of the 
CDSC. 

The CDSC on Class B shares will be waived upon the death or disability (as 
defined in section 72(m)(7) of the Code) of any investor, provided the 
account is registered (i) in the case of a deceased individual, solely in the 
deceased individual's name, (ii) in the case of a disabled individual, solely 
or jointly in the disabled individual's name or (iii) in the name of a living 
trust for the benefit of the deceased or disabled individual. The CDSC on 
Class B shares will also be waived in the case of redemptions of shares of 
the Fund pursuant to a systematic withdrawal plan. In addition, the CDSC on 
Class B shares will be waived in the case of distributions from an IRA, 
SAR-SEP or any other retirement plan qualified under section 401(a), 401(k) 
or 403(b) of the Code, due to death or disability, or in the case of required 
minimum distributions from any such retirement plan due to attainment of age 
70-1/2. The CDSC on Class B shares will be waived in the case of 
distributions from a retirement plan qualified under Section 401(a) of the 
Code due to (i) returns of excess contribution to the plan, (ii) retirement 
of a participant in the plan, (iii) a borrowing from the plan (repayments of 
borrowings, however, will constitute new sales for purposes of assessing the 
CDSC), (iv) "financial hardship" of the participant in the plan, as that term 
is defined in Treasury Regulation 401(k)-1(d)(2), as amended from time to 
time, and (v) termination of employment of the participant in the plan 
(excluding, however, a partial or other termination of the plan). The CDSC on 
Class B shares will also be waived upon redemptions by: (i) officers of the 
Trust; (ii) any of the subsidiary companies of Sun Life; (iii) eligible 
Directors, officers, employees, (including retired employees) and agents of 
MFS, Sun Life or any of their subsidiary companies; (iv) any trust, pension, 
profit-sharing or any other benefit plan for such persons; (v) any trustees 
and retired trustees of any investment company for which FSI serves as 
distributor or principal underwriter; and (vi) certain family members of such 
individuals and their spouses, provided in each case that 

                                      16 
<PAGE> 

the shares will not be resold except to the Fund. The CDSC on Class B shares 
will also be waived in the case of redemptions by any employee or registered 
representative of any dealer or other financial institution which has a sales 
agreement with FSI, by certain family members of any such employee or 
representative and their spouses, by any trust, pension, profit-sharing or 
other retirement plan for the sole benefit of such employee or representative 
and by clients of the MFS Asset Management Group. A retirement plan qualified 
under section 401(a) of the Internal Revenue Code of 1986, as amended, (a 
"Retirement Plan") that has invested its assets in Class B shares of one or 
more of the MFS Funds for more than 10 years from the later to occur of (i) 
January 1, 1993 or (ii) the date the Retirement Plan first invests its assets 
in Class B shares of one or more of the funds in the MFS Funds will have the 
CDSC on Class B shares waived in the case of a redemption of all the 
Retirement Plan's shares (including any Class A shares) in all MFS Funds 
(i.e., all the assets of the Retirement Plan invested in the MFS Funds are 
withdrawn), except that if, immediately prior to the redemption, the 
aggregate amount invested by the Retirement Plan in Class B shares of the MFS 
Funds (excluding the reinvestment of distributions) during the prior four 
year period equals 50% or more of the total value of the Retirement Plan's 
assets in the MFS Funds, then the CDSC will not be waived. The CDSC on Class 
B shares may also be waived in connection with the acquisition or liquidation 
of the assets of other investment companies or personal holding companies. 

Conversion of Class B Shares. Class B shares of the Fund that remain 
outstanding for approximately eight years will convert to Class A shares of 
the Fund. Shares purchased through the reinvestment of distributions paid in 
respect of Class B shares will be treated as Class B shares for purposes of 
the payment of the distribution and service fees under the Distribution Plan 
applicable to Class B shares. However, for purposes of conversion to Class A 
shares, all shares in a shareholder's account that were purchased through the 
reinvestment of dividends and distributions paid in respect of Class B shares 
(and which have not converted to Class A shares as provided in the following 
sentence) will be held in a separate sub-account. Each time any Class B 
shares in the shareholder's account (other than those in the sub-account) 
convert to Class A shares, a portion of the Class B shares then in the 
sub-account will also convert to Class A shares. The portion will be 
determined by the ratio that the shareholder's Class B shares not acquired 
through reinvestment of dividends and distributions that are converting to 
Class A shares bear to the shareholder's total Class B shares not acquired 
through such reinvestment. The conversion of Class B shares to Class A shares 
is subject to the continuing availability of a ruling from the Internal 
Revenue Service or an opinion of counsel that such conversion will not 
constitute a taxable event for federal tax purposes. There can be no 
assurance that such ruling or opinion will be available, and the conversion 
of Class B shares to Class A shares will not occur if such ruling or opinion 
is not available. In such event, Class B shares would continue to be subject 
to higher expenses than Class A shares for an indefinite period. 

General: Except as described below, the minimum initial investment is $1,000 
per account and the minimum additional investment is $50 per account. 
Accounts being established for monthly automatic investments and under 
payroll savings programs and tax-deferred retirement programs (other than 
IRAs) involving the submission of investments by means of group remittal 
statements are subject to a $50 minimum on initial and additional investments 
per account. The minimum initial investment for IRAs is $250 per account and 
the minimum additional investment is $50 per account. Accounts being 
established for participation in the Automatic Exchange Plan are subject to a 
$50 minimum on initial and additional investments per account. There are also 
other limited exceptions to these minimums for certain tax-deferred 
retirement programs. Any minimums may be changed at any time at the 
discretion of FSI. The Fund reserves the right to cease offering its shares 
for sale at any time. 

For shareholders who elect to participate in certain investment programs 
(e.g., the automatic investment plan) or other shareholder services FSI or 
its affiliates may either (i) give a gift of nominal value, such as a 
hand-held calculator, or (ii) make a nominal charitable contribution on their 
behalf. 

A shareholder whose shares are held in the name of, or controlled by, an 
investment dealer, might not receive many of the privileges and services from 
the Fund (such as Right of Accumulation, Letter of Intent and certain 
recordkeeping services) that the Fund ordinarily provides. 

The Fund and FSI each reserve the right to reject any specific purchase order 
or to restrict purchases by a particular purchaser (or group of related 
purchasers). The Fund or FSI may reject or restrict purchases of the Fund's 
shares by a particular purchaser or 

                                      17 
<PAGE> 

group, for example, when a pattern of frequent purchases and sales of shares 
of the Fund is evident, or if the purchase and sale orders are, or a 
subsequent abrupt redemption might be, of a size that would disrupt 
management of the Fund. The Fund and FSI intend specifically to exercise this 
right in order to reject or restrict purchases by market timers (including 
asset allocators) and the shareholder(s) whose accounts are exchanged 
periodically based on an arrangement with or advice from such persons or 
whose transactions seem to follow a timing pattern. In particular, action may 
be taken if: (i) more than two exchange purchases are effected in a timed 
account in the same calendar quarter; or (ii) a purchase would result in 
shares being held in timed accounts by an individual or firm representing 
more than (x) one percent of the Fund's net assets or (y) specified dollar 
amounts in the case of certain funds in the MFS Funds, which may include the 
Fund and which may change from time to time. The Fund and FSI each reserve 
the right to request holders of timed accounts to redeem their shares at net 
asset value, less any CDSC otherwise applicable, if either of these 
restrictions is violated. 

Securities dealers and other financial institutions may receive different 
compensation with respect to sales of Class A and Class B shares. 

The Glass-Steagall Act prohibits national banks from engaging in the business 
of underwriting, selling or distributing securities. Although the scope of 
the prohibition has not been clearly defined, FSI believes that such Act 
should not preclude banks from entering into agency agreements with FSI (as 
described above). If, however, a bank were prohibited from so acting, the 
Trustees would consider what actions, if any, would be necessary to continue 
to provide efficient and effective shareholder services. It is not expected 
that shareholders would suffer any adverse financial consequence as a result 
of these occurrences. In addition, state securities laws on this issue may 
differ from the interpretation of federal law expressed herein, and banks and 
financial institutions may be required to register as broker-dealers pursuant 
to state law. 

Exchanges 
Subject to the requirements set forth below, some or all of the shares 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) at net asset value. Shares of 
one class may not be exchanged for shares of any other class. Exchanges will 
be made only after instructions in writing or by telephone (an "Exchange 
Request") are received for an established account by the Shareholder 
Servicing Agent 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 the MFS FUNDamental 401(k) Plan or 
another similar 401(k) recordkeeping system made available by MFS Service 
Center, Inc.) or all the shares in the account. If the Exchange Request is 
received by the Shareholder Servicing Agent on any business day prior to the 
close of regular trading on the New York Stock Exchange (the "Exchange"), the 
exchange usually will occur on that day if all the requirements set forth 
above have been complied with at that time. No more than five exchanges may 
be made in any one Exchange Request by telephone. Additional information 
concerning this exchange privilege and prospectuses for any of the other MFS 
Funds may be obtained from investment dealers or the Shareholder Servicing 
Agent. A shareholder should read the prospectus of the other MFS Fund and 
consider the differences in objectives and policies before making any 
exchange. For federal and (generally) state income tax purposes, an exchange 
is treated as a sale of the shares exchanged and, therefore, an exchange 
could result in a gain or loss to the shareholder making the exchange. 
Exchanges by telephone are automatically available to most non-retirement 
plan accounts and certain retirement plan accounts. For further information 
regarding exchanges by telephone see "Redemptions By Telephone." The exchange 
privilege (or any aspect of it) may be changed or discontinued and is subject 
to certain limitations, including certain restrictions on purchases by market 
timer accounts (see "Purchases"). 

Redemptions and Repurchases 
A shareholder may withdraw all or any portion of the amount in his account on 
any date on which the Fund is open for business by redeeming shares at their 
net asset value or by selling such shares to the Fund through a dealer (a 
repurchase). Since the net asset value of shares of the account fluctuate, 
redemptions or repurchases, which are taxable transactions are likely to 

                                      18 
<PAGE> 

result in gains or losses to the shareholder. When a shareholder withdraws an 
amount from his account, the shareholder is deemed to have tendered for 
redemption a sufficient number of full and fractional shares in his account 
to cover the amount withdrawn. 

Certain purchases may, however, be subject to a CDSC in the event of certain 
redemption transactions (see "Contingent Deferred Sales Charge" below). For 
the convenience of shareholders, the Fund has arranged for different 
procedures for redemption and repurchase. The proceeds of a redemption or 
repurchase will normally be available within seven days, except for shares 
purchased, or received in exchange for shares purchased, by check (including 
certified checks or cashier's checks); payment of redemption proceeds may be 
delayed for 15 days from the purchase date in an effort to assure that such 
check has cleared. Payment of redemption proceeds 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. 

A. Redemption By Mail--Each shareholder has the right to redeem all or any 
portion of the shares in his account by mailing or delivering to the 
Shareholder Servicing Agent (see back cover for address) a stock power with a 
written request for redemption or a letter of instruction, together with his 
share certificates (if any were issued), all in "good order" for transfer. 
"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 and the signature(s) 
must be guaranteed in the manner set forth below under the caption "Signature 
Guarantee." In addition, in some cases "good order" may require the 
furnishing of additional documents. The Shareholder Servicing Agent may make 
certain de minimis exceptions to the above requirements for redemption. 
Within seven days after receipt of a redemption request by the Shareholder 
Servicing Agent in "good order," the Fund will make payment in cash of the 
net asset value of the shares next determined after such redemption request 
was received, reduced by the amount of any applicable CDSC and the amount of 
any income tax required to be withheld, except during any period in which the 
right of redemption is suspended or date of payment is postponed because the 
Exchange is closed or trading on such Exchange is restricted or to the extent 
otherwise permitted by the Investment Company Act of 1940 (the "1940 Act"), 
if an emergency exists (see "Tax Status"). 

B. Redemption By Telephone--Each shareholder may redeem an amount from his 
account by telephoning toll-free at (800) 225-2606. Shareholders wishing to 
avail themselves of this telephone redemption privilege must so elect on 
their Account Application, designate thereon a commercial bank and account 
number to receive the proceeds of such redemption, and sign the Account 
Application Form with the signature(s) guaranteed in the manner set forth 
below under the caption "Signature Guarantee". The proceeds of such a 
redemption, reduced by the amount of any applicable CDSC described above and 
the amount of any income tax required to be withheld, are mailed by check to 
the designated account, without charge. As a special service, investors may 
arrange to have proceeds in excess of $1,000 wired in federal funds to the 
designated account. If a telephone redemption request is received by the 
Shareholder Servicing Agent by the close of regular trading on the Exchange 
on any business day, shares will be redeemed at the closing net asset value 
of the Fund on that day. Subject to the conditions described in this section, 
proceeds of a redemption are normally mailed or wired on the next business 
day following the date of receipt of the order for redemption. The 
Shareholder Servicing Agent will not be responsible for any losses resulting 
from unauthorized telephone transactions if it follows reasonable procedures 
designed to verify the identity of the caller. The Shareholder Servicing 
Agent 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. 

C. Repurchase Through a Dealer--If a shareholder desires to sell his shares 
at net asset value through his securities dealer (a repurchase), the 
shareholder can place a repurchase order with his dealer, who may charge the 
shareholder a fee. Net asset value is calculated on the day the dealer places 
the order with FSI, as the Fund's agent. If the dealer receives the 
shareholder's order prior to the close of regular trading on the Exchange and 
communicates it to FSI on the same day before FSI closes for business, the 
shareholder will receive the net asset value calculated on that day reduced 
by the amount of any applicable CDSC and the amount of any income tax 
required to be withheld. 

Signature Guarantee: In order to protect shareholders against fraud to the 
greatest extent possible, the Fund requires in certain instances as indicated 
above that the shareholder's signature be guaranteed. In these cases the 
shareholder's signature must 

                                      19 
<PAGE> 

be guaranteed by an eligible bank, broker, dealer, credit union, national 
securities exchange, registered securities association, clearing agency or 
savings association. Signature guarantees shall be accepted in accordance 
with policies established by the Shareholder Servicing Agent. 

Shareholders of the Fund who have redeemed their shares have a one-time right 
to reinvest the redemption proceeds in the same class of shares of any of the 
MFS Funds (if shares of such Fund are available for sale) at net asset value 
(with a credit for any CDSC paid) within 90 days of the redemption pursuant 
to the Reinstatement Privilege. If the shares credited for any CDSC paid are 
then redeemed within six years of the initial purchase in the case of Class B 
shares, or within 12 months of the initial purchase for certain Class A 
purchases, a CDSC will be imposed upon redemption. Such purchases under the 
Reinstatement Privilege are subject to all limitations in the Statement of 
Additional Information regarding this privilege. 

Subject to the Fund's compliance with applicable regulations, the Fund has 
reserved the right to pay the redemption or repurchase price of shares of the 
Fund, either totally or partially, by a distribution in kind of portfolio 
securities (instead of cash). The securities so distributed would be valued 
at the same amount as that assigned to them in calculating the net asset 
value for the shares being sold. If a shareholder received a distribution in 
kind, the shareholder could incur brokerage or transaction charges in 
converting the securities to cash. 

Due to the relatively high cost of maintaining small accounts, the Fund 
reserves the right to redeem shares in any account for their then-current 
value (which will be promptly paid to the shareholder) if at any time the 
total investment in such account drops below $500 because of redemptions, 
except in the case of accounts established for monthly automatic investments 
and certain payroll savings programs, Automatic Transfer Plan accounts and 
tax-deferred retirement plans, for which there is a lower minimum investment 
requirement. See "Purchases". Shareholders will be notified that the value of 
their account is less than the minimum investment requirement and allowed 60 
days to make an additional investment before the redemption is processed. No 
CDSC will be imposed with respect to such involuntary redemptions. 

Contingent Deferred Sales Charge--Investments ("Direct Purchases") will be 
subject to a CDSC for a period of 12 months (in the case of purchases of $1 
million or more of Class A shares) or six years (in the case of purchases of 
Class B shares). Purchases of Class A shares made during a calendar month, 
regardless of when during the month the investment occurred, will age one 
month on the last day of the month and each subsequent month. Class B shares 
purchased on or after January 1, 1993 will be aggregated on a calendar month 
basis--all transactions made during a calendar month, regardless of when 
during the month they have occurred, will age one year at the close of 
business on the last day of such month in the following calendar year and 
each subsequent year. For Class B shares purchased prior to January 1, 1993, 
transactions will be aggregated on a calendar year basis--all transactions 
made during a calendar year, regardless of when during the year they have 
occurred, will age one year at the close of business on December 31 of that 
year and each subsequent year. At the time of a redemption, the amount by 
which the value of a shareholder's account for a particular class represented 
by Direct Purchases exceeds the sum of the six calendar year aggregations (12 
months in the case of purchases of $1 million or more of Class A shares) of 
Direct Purchases may be redeemed without charge ("Free Amount"). Moreover, no 
CDSC is ever assessed on additional shares acquired through the automatic 
reinvestment of dividends or capital gain distributions ("Reinvested 
Shares"). 

Therefore, at the time of redemption of shares of a particular class, (i) any 
Free Amount is not subject to the CDSC, and (ii) the amount of redemption 
equal to the then-current value of Reinvested Shares is not subject to the 
CDSC, but (iii) any amount of the redemption in excess of the aggregate of 
the then-current value of Reinvested Shares and the Free Amount is subject to 
a CDSC. The CDSC will first be applied against the amount of Direct Purchases 
which will result in any such charge being imposed at the lowest possible 
rate. The CDSC to be imposed upon redemptions will be calculated as set forth 
in "Purchases" above. 

The applicability of the CDSC will be unaffected by exchanges or transfers of 
registration. 

                                      20

Distribution Plans 
The Trustees have adopted separate distribution plans for Class A and Class B 
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 plans would benefit the Fund and its shareholders. 

Class A Distribution Plan. The Class A Rule Distribution Plan provides that 
the Fund will pay FSI a distribution/service fee aggregating up to (but not 
necessarily all of) 0.35% of the average daily net assets attributable to 
Class A shares annually in order that FSI may pay expenses on behalf of the 
Fund related to the distribution and servicing of Class A shares. The 
expenses to be paid by FSI on behalf of the Fund include a service fee to 
securities dealers which enter into a sales agreement with FSI of up to 0.25% 
of the Fund's average daily net assets attributable to Class A shares that 
are owned by investors for whom such securities dealer is the holder or 
dealer of record. This fee is intended to be partial consideration for all 
personal services and/or account maintenance services rendered by the dealer 
in the distribution of Class A shares. FSI may from time to time reduce the 
amount of the service fee paid for shares sold prior to a certain date. FSI 
will also retain a distribution fee of 0.10% of the Fund's average daily net 
assets attributable to Class A shares as partial consideration for services 
performed and expenses incurred in the performance of FSI's obligations under 
its distribution agreement with the Fund. In addition, to the extent that the 
aggregate of the foregoing fees does not exceed 0.35% per annum of the 
average daily net assets of the Fund attributable to Class A shares, the Fund 
is permitted to pay other distribution-related expenses, including 
commissions to dealers and payments to wholesalers employed by FSI for sales 
at or above a certain dollar level. Fees payable under the Class A 
Distribution Plan are charged to, and therefore reduce, income allocated to 
Class A shares. Service fees may be reduced for a securities dealer that is 
the holder or dealer of record for an investor who owns shares of the Fund 
having a 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. FSI or its affiliates are entitled to retain all service fees payable 
under the Class A 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 FSI or 
its affiliates for shareholder accounts. Certain banks and other financial 
institutions that have agency agreements with FSI will receive service fees 
that are the same as service fees to dealers. 

Class B Distribution Plan. The Class B Distribution Plan provides that the 
Fund will pay FSI a daily distribution fee equal on an annual basis to 0.75% 
of the Fund's average daily net assets attributable to Class B shares and 
will pay FSI a service fee of up to 0.25% per annum of the Fund's average 
daily net assets attributable to Class B shares (which FSI will in turn pay 
to securities dealers which enter into a sales agreement with FSI at a rate 
of up to 0.25% per annum of the Fund's average daily net assets attributable 
to Class B shares owned by investors for whom that securities dealer is the 
holder or dealer of record). This service fee is intended to be additional 
consideration for all personal services and/or account maintenance services 
rendered by the dealer with respect to Class B shares. Fees payable under the 
Class B Distribution Plan are charged to, and therefore reduce, income 
allocated to Class B shares. The Class B Distribution Plan also provides that 
FSI will receive all CDSCs attributable to Class B shares (see "Redemptions 
and Repurchases of Shares"), which do not reduce the distribution fee. FSI 
will pay commissions to dealers of 3.75% of the purchase price of Class B 
shares purchased through dealers. FSI will also advance to dealers the first 
year service fee at a rate equal to 0.25% of the purchase price of such 
shares and as compensation therefor, FSI may retain the service fee paid by 
the Fund with respect to such shares for the first year after purchase. 
Therefore, the total amount paid to a dealer upon the sale of shares is 4.00% 
of the purchase price of the shares (commission rate of 3.75% plus service 
fee equal to 0.25% of the purchase price). Dealers will become eligible for 
additional service fees with respect to such shares commencing in the 
thirteenth month following the purchase. Dealers may from time to time be 
required to meet certain criteria in order to receive service fees. FSI or 
its affiliates are entitled to retain all service fees payable under the 
Class B 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 FSI or its 
affiliates for shareholder accounts. The purpose of the payments to FSI under 
the Class B Distribution Plan is to compensate FSI for its distribution 
services to the Fund. Since FSI's compensation is not directly tied to its 
expenses, the amount of compensation received by FSI during any year may be 
more or less than its actual expenses. For this reason, this type of 
distribution fee arrangement is characterized by the staff of the SEC as 
being of the "compensation" variety. However, the Fund is not liable for any 
expenses 

                                      21 
<PAGE> 

incurred by FSI in excess of the amount of compensation it receives. The 
expenses incurred by FSI, including commissions to dealers, are likely to be 
greater than the distribution fees for the next several years, but thereafter 
such expenses may be less than the amount of the distribution fees. Certain 
banks and other financial institutions that have agency agreements with FSI 
will receive agency transaction and service fees that are the same as 
commissions and service fees to dealers. 

Distributions 
The Fund intends to pay substantially all of its net investment income for 
any calendar year to its shareholders as dividends on an annual basis. In 
addition, the Fund may make one or more distributions during the calendar 
year to its shareholders from any long-term capital gains. The Fund also may 
make one or more distributions during the calendar year to its shareholders 
from short- term capital gains. Shareholders may elect to receive dividends 
and capital gain distributions in either cash or additional shares of the 
same class in respect of which the distribution is made. See "Tax Status" and 
"Shareholder Services-- Distribution Options" below. Distributions paid by 
the Fund with respect to Class A shares will generally be greater than those 
paid with respect to Class B shares because expenses attributable to Class B 
shares will generally be higher. 

Tax Status 
The Fund is treated as an entity separate from the other series of the Trust 
for federal income tax purposes. In order to minimize the taxes the Fund 
would otherwise be required to pay, the Fund intends to qualify each year as 
a "regulated investment company" under Subchapter M of the Code, and to make 
distributions to its shareholders in accordance with the timing requirements 
imposed by the Code. It is not expected that the Fund will be required to pay 
any federal income or excise taxes, although foreign-source income earned by 
the Fund may be subject to foreign withholding taxes. Shareholders of the 
Fund normally will have to pay federal income taxes, and any state and local 
taxes, on the dividends and capital gain distributions they receive from the 
Fund, whether paid in cash or in additional shares. A portion of the 
dividends received from the Fund (but none of the Fund's capital gain 
distributions) may qualify for the dividends-received deduction for 
corporations. A statement setting forth the federal income tax status of all 
dividends and distributions for that calendar year, including the portion 
taxable as ordinary income, the portion taxable as long-term capital gains, 
the portion, if any, representing a return of capital (which is generally 
free of current taxes but results in a basis reduction) and the amount, if 
any, of federal income tax withheld will be sent to each shareholder promptly 
after the end of such year. 

The Fund intends to withhold U.S. federal income tax at the rate of 30% on 
any payments that are subject to such withholding and are made to persons who 
are neither citizens nor residents of the U.S., regardless of whether a lower 
rate may be permitted under an applicable treaty. The Fund is also required 
in certain circumstances to apply backup withholding of 31% of 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, however, will 
not be applied to payments which 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 and 
should consult their own tax advisor as to the tax consequences of an 
investment in the Fund. 

Net Asset Value 
The net asset value per share of each class of the Fund is determined each 
day during which the Exchange is open for trading. This determination is made 
once each day as of the close of regular trading on such Exchange by 
deducting the amount of the liabilities attributable to the class from the 
value of the Fund's assets and dividing the difference by the number of 
outstanding shares of the class outstanding. Assets in the Fund's portfolio 
are valued on the basis of their current values or otherwise at their fair 
values, as described in the Statement of Additional Information. All 
investments and assets are expressed in U.S. dollars based upon current 
currency exchange rates. The net asset value of each class of shares is 
effective for orders received by the dealer prior to its calculation and 
received by FSI prior to the close of that business day. 

Description of Shares, Voting Rights and Liabilities 
The Fund, one of two series of the Trust, has two classes of shares, entitled 
Class A and Class B Shares of Beneficial Interest (without par value). The 
Trust has reserved the right to create and issue additional classes and 
series of shares, in which case 

                                      22 
<PAGE> 

each class of shares of a series would participate equally in the earnings, 
dividends and assets attributable to that class of shares of that particular 
series. Shareholders are entitled to one vote for each share held and shares 
of each series would be entitled to vote separately to approve investment 
advisory agreements or changes in investment restrictions, but shares of all 
series would vote together in the election of Trustees and ratification of 
selection of accountants. Additionally, each class of shares of a series will 
vote separately on any material increases in the fees under its Distribution 
Plan or on any other matter that affects solely that class of shares, but 
will otherwise vote together with all other classes of shares of the series 
on all other matters. The Trust does not intend to hold annual shareholder 
meetings. The Declaration of Trust provides that a Trustee may be removed 
from office in certain instances (see "Description of Shares, Voting Rights 
and Liabilities" in the Statement of Additional Information). 

Each share of a class of the Fund represents an equal proportionate interest 
in the Fund with each other class share, subject to the liabilities of the 
particular class. Shares have no pre-emptive or conversion rights (except as 
set forth above "Purchases-- Conversion of Class B Shares"). Shares are fully 
paid and non-assessable. Should the Fund be liquidated, shareholders of each 
class are entitled to share pro rata in the net assets attributable to that 
class available for distribution to shareholders. Shares will remain on 
deposit with the Shareholder Servicing Agent and certificates will not be 
issued except in connection with pledges and assignments and in certain other 
limited circumstances. 

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 risk of a shareholder incurring financial loss on 
account of shareholder liability is limited to circumstances in which both 
inadequate insurance (e.g., fidelity bonding and errors and omissions 
insurance) existed and the Trust itself was unable to meet its obligations. 

Performance Information 
From time to time, the Fund will provide total rate of return quotations for 
each class of shares and may also quote fund rankings in the relevant fund 
category from various sources, such as the Lipper Analytical Services, Inc. 
and Wiesenberger Investment Companies Service. Total rate of return 
quotations will reflect the average annual percentage change over stated 
periods in the value of an investment in a class of shares of the Fund made 
at the maximum public offering price of shares of that class with all 
distributions reinvested and which, if quoted for periods of six years or 
less, will give effect to the imposition of the CDSC assessed upon 
redemptions of the Fund's Class B shares. Such total rate of return 
quotations may be accompanied by quotations which do not reflect the 
reduction in value of the initial investment due to the sales charge or the 
deduction of a CDSC, and which will thus be higher. The Fund's total rate of 
return quotations are based on historical performance and are not intended to 
indicate future performance. Total rate of return reflects all components of 
investment return over a stated period of time. The Fund's quotations may 
from time to time be used in advertisements, shareholder reports or other 
communications to shareholders. For a discussion of the manner in which the 
Fund will calculate its total rate of return, see the Statement of Additional 
Information. In addition to information provided in shareholder reports, the 
Fund may, in its discretion, from time to time, make a list of all or a 
portion of its holdings available to investors upon request. 

8. SHAREHOLDER SERVICES 

Shareholders with questions concerning the shareholder services described 
below or concerning other aspects of the Fund should contact the Shareholder 
Servicing Agent (see back cover for address and phone number). 

Account and Confirmation Statements--Each shareholder will receive 
confirmation statements showing the transaction activity in his account. At 
the end of each calendar year, each shareholder will receive income tax 
information regarding reportable dividends and capital gain distributions for 
that year (see "Tax Status"). 

Distribution Options--The following options are available to all accounts 
(except Systematic Withdrawal Plan accounts) and may be changed as often as 
desired by notifying the Shareholder Servicing Agent: 

  --Dividends and capital gain distributions reinvested in additional shares. 
This option will be assigned if no other option is specified; 

                                      23 
<PAGE> 

- --Dividends (including short-term capital gains) in cash; long-term capital 
gain distributions reinvested in additional shares; 

  --Dividends and capital gain distributions in cash. 

Reinvestments (net of any tax withholding) will be made in additional full 
and fractional shares of the same class of shares at the net asset value in 
effect at the close of business on the record date. Dividends and capital 
gain distributions in amounts less than $10 will automatically be reinvested 
in additional shares of the Fund. Any request to change a distribution option 
must be received by the Shareholder Servicing Agent by the record date for a 
dividend or distribution in order to be effective for that dividend or 
distribution. No interest will accrue on amounts represented by uncashed 
distribution or redemption checks. 

Investment and Withdrawal Programs --For the convenience of shareholders, the 
Fund makes available the following programs designed to enable shareholders 
to add to their investment in an account with the Fund or withdraw from it 
with a minimum of paper work. 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 as described 
in the Statement of Additional Information) anticipates purchasing $50,000 or 
more of Class A shares of the Fund alone or in combination with shares of all 
classes of all MFS Funds or the MFS Fixed Fund (a bank collective investment 
fund) within a 13-month period (or 36-month period for purchases of $1 
million or more), the shareholder may obtain such shares of the Fund at the 
same reduced sales charge as though the total quantity were invested in one 
lump sum, subject to escrow agreements and the appointment of an attorney for 
redemptions from the escrow amount if the intended purchases are not 
completed, by completing the Letter of Intent section of the Account 
Application. 

Right of Accumulation: A shareholder qualifies for cumulative quantity 
discounts on purchases of Class A shares when his new investment, together 
with the current offering price value of all holdings of any class of shares 
of that shareholder in the MFS Funds or the MFS Fixed Fund (a bank collective 
investment fund) reaches a discount level. 

Distribution Investment Program: Shares of a particular class of the Fund may 
be sold at net asset value (and without any applicable CDSC) through the 
automatic reinvestment of dividend and capital gain distributions from the 
same class of another MFS Fund. Furthermore, distributions made by the Fund 
may be automatically invested at net asset value in shares of the same class 
of another MFS Fund, if shares of such Fund are available for sale and 
without any applicable CDSC). 

Systematic Withdrawal Plan: A shareholder (except a $3 Million Shareholder) 
may direct the Shareholder Servicing Agent to send him (or anyone he 
designates) regular periodic payments, as designated on the Account 
Application and 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 shares in any 
year pursuant to a SWP will not be subject to a CDSC and are generally 
limited to 10% of the value of the account at the time of the establishment 
of the SWP. The CDSC will not be waived in the case of SWP redemptions of 
Class A shares which are subject to a CDSC. 

Dollar Cost Averaging Programs-- 

Automatic Investment Plan: Cash investments of $50 or more may be made 
through a shareholder's checking account twice monthly, monthly or quarterly. 
Required forms are available from the Shareholder Servicing Agent or 
investment dealers. 

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 transfers 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. Under the Automatic 
Exchange Plan, transfers of at least $50 each may be made to up to four 
different funds. A shareholder should consider the objectives and policies of 
a fund and review its prospectus before electing to transfer money into such 
fund through the Automatic Exchange Plan. No transaction fee is imposed in 
connection with transfer transactions under the Automatic Exchange Plan. 
However, transfers of shares of MFS Money Market Fund, MFS Government Money 
Market Fund or Class A 

                                      24 
<PAGE> 

shares of MFS Cash Reserve Fund will be subject to any applicable sales 
charge. For federal and (generally) state income tax purposes, a transfer is 
treated as a sale of the shares transferred and, therefore, could result in a 
capital gain or loss to the shareholder making the transfer. See the 
Statement of Additional Information for further information concerning the 
Automatic Exchange Plan. Investors should consult their tax advisers for 
information regarding the potential capital gain and loss consequences of 
transactions under the Automatic Exchange Plan. 

Because a dollar cost averaging program involves periodic purchases of shares 
regardless of fluctuating share offering prices, a shareholder should 
consider his financial ability to continue his purchases through periods of 
low price levels. Maintaining a dollar cost averaging program concurrently 
with a withdrawal program could be disadvantageous because of the sales 
charges included in share purchases in the case of Class A shares and because 
of the assessment of the CDSC for certain share redemptions in the case of 
Class A shares. 

Tax-Deferred Retirement Plans--Shares of the Fund may be purchased by all 
types of tax-deferred retirement plans, including IRAs, SEP-IRA plans, 401(k) 
plans, 403(b) plans and other corporate pension and profit-sharing plans. 
Investors should consult with their tax adviser before establishing any of 
the tax-deferred retirement plans described above. 

The Fund's Statement of Additional Information, dated April 1, 1994, contains

related to (i) investment policies and restrictions, including the purchase 
and sale of options, Futures Contracts, Options on Futures Contracts, Forward 
Contracts and Options on Foreign Currencies, (ii) the Trustees, officers and

                        DESCRIPTION OF INDUSTRY SECTORS

The Fund seeks to achieve its investment objective by varying the weighting 
of its portfolio among the following 15 industry sectors (i.e., industry 
groupings). 

(1) Autos and Housing Sector: companies engaged in the design, production and 
sale of automobiles, automobile parts, mobile homes and related products, and 
in the design, construction, renovation and refurbishing of residential 
dwellings. The value of automobile industry securities is affected by foreign 
competition, consumer confidence, consumer debt and installment loan rates. 
The housing construction industry is affected by the level of consumer 
confidence, consumer debt, mortgage rates and the inflation outlook. 

(2) Consumer Goods and Services Sector: companies engaged in providing 
consumer goods and services such as: the design, processing, production and 
storage of packaged, canned, bottled and frozen foods and beverages; and the 
design, production and sale of home furnishings, appliances, clothing, 
accessories, cosmetics and perfumes. Certain such companies are subject to 
government regulation affecting the permissibility of using various food 
additives and production methods, which regulations could affect company 
profitability. Also, the success of food- and fashion-related products may be 
strongly affected by fads, marketing campaigns and other factors affecting 
supply and demand. 

(3) Defense and Aerospace Sector: companies engaged in the research, 
manufacture or sale of products or services related to the defense and 
aerospace industries, such as: air transport; data processing or 
computer-related services; communications systems; military weapons and 
transportation; general aviation equipment, missiles, space launch vehicles 
and spacecraft; units for guidance, propulsion and control of flight 
vehicles; and airborne and ground-based equipment essential to the test, 
operation and maintenance of flight vehicles. Since such companies rely 
largely on U.S. (and other) governmental demand for their products and 
services, their financial conditions are heavily influenced by federal (and 
other governmental) defense spending policies. 

(4) Energy Sector: companies in the energy field, including oil, gas, 
electricity and coal as well as nuclear, geo- thermal, oil shale and solar 
sources of energy. The business activities of companies comprising this 
sector may include: production, generation, transmission, marketing, control 
or measurement of energy or energy fuels; provision of component parts or 
services to companies engaged in such activities; energy research or 
experimentation; environmental activities related to the solution of energy 
problems; and activities resulting from technological advances or research 
discoveries in the energy field. The value of such companies' securities 
varies based on the price and supply of energy fuels and may be affected by 
events relating to international politics, energy conservation, the success 
of exploration projects, and the tax and other regulatory policies of various 
governments. 

(5) Financial Services Sector: companies providing financial services to 
consumers and industry, such as: commercial banks and savings and loan 
associations; consumer and industrial finance companies; securities brokerage 
companies; leasing companies; and firms in all segments of the insurance 
field (such as multiline, property and casualty, and life insurance). These 
kinds of companies are subject to extensive governmental regulations, some of 
which regulations are currently being studied by Congress. The profitability 
of these groups may fluctuate significantly as a result of volatile interest 
rates and general economic conditions. 

(6) Health Care Sector: companies engaged in the design, manufacture or sale 
of products or services used in connection with health care or medicine, such 
as: pharmaceutical companies; firms that design, manufacture, sell or supply 
medical, dental and optical products, hardware or services; companies 
involved in biotechnology, medical diagnostic and biochemical research and 
development; and companies involved in the operation of health care 
facilities. Many of these companies are subject to government regulation, 
which could affect the price and availability of their products and services. 
Also, products and services in this sector could quickly become obsolete. 

                                      26 
<PAGE> 

(7) Heavy Industry Sector: companies engaged in the research, development, 
manufacture or marketing of products, processes or services related to the 
agriculture, chemicals, containers, forest products, non-ferrous metals, 
steel and pollution control industries, such as: synthetic and natural 
materials, for example, chemicals, plastics, fertilizers, gases, fibers, 
flavorings and fragrances; paper; wood products; steel and cement. Certain 
companies in this sector are subject to regulation by state and federal 
authorities, which could require alteration or cessation of production of a 
product, payment of fines or cleaning of a disposal site. In addition, since 
some of the materials and processes used by these companies involve hazardous 
components, there are risks associated with their production, handling and 
disposal. The risk of product obsolescence is also present. 

(8) Leisure Sector: companies engaged in the design, production or 
distribution of goods or services in the leisure industry, such as: 
television and radio broadcast or manufacture; motion pictures and 
photography; recordings and musical instruments; publishing; sporting goods, 
camping and recreational equipment; sports arenas; toys and games; amusement 
and theme parks; travel-related services and airlines; hotels and motels; 
fast food and other restaurants; and gaming casinos. Many products produced 
by companies in this sector--for example, video and electronic games--may 
quickly become obsolete. 

(9) Machinery and Equipment Sector: companies engaged in the research, 
development or manufacture of products, processes or services relating to 
electrical equipment, machinery, pollution control and construction services, 
such as: transformers, motors, turbines, hand tools, earth-moving equipment 
and waste disposal services. The profitability of most companies in this 
group may fluctuate significantly in response to capital spending and general 
economic conditions. Since some of the materials and processes used by these 
companies involve hazardous components, there are risks associated with their 
production, handling and disposal. The risk of product obsolescence is also 
present. 

(10) Natural Resources Sector: companies engaged in exploration, mining, 
processing or dealing in gold, silver, platinum or other natural resources or 
companies which, in turn, invest in companies engaged in these activities. A 
significant portion of this sector may be represented by securities of 
foreign companies, and investors should understand the special risks related 
to such an investment emphasis. Also, such securities depend heavily on 
prices in metals or other natural resources, some of which may experience 
extreme price volatility based on international economic and political 
developments. 

(11) Retailing Sector: companies engaged in the retail distribution of home 
furnishings, food products, clothing, pharmaceuticals, leisure products and 
other consumer goods, such as: department stores; supermarkets; and retail 
chains specializing in particular items such as shoes, toys or 
pharmaceuticals. The value of securities in this sector will fluctuate based 
on consumer spending patterns, which depend on inflation and interest rates, 
level of consumer debt and seasonal shopping habits. The success or failure 
of a particular company in this highly competitive sector will depend on such 
company's ability to predict rapidly changing consumer tastes. 

(12) Technology Sector: companies which are expected to have or develop 
products, processes or services which will provide or will benefit 
significantly from technological advances and improvements or future 
automation trends in the office and factory, such as: semiconductors; 
computers and peripheral equipment; scientific instruments; computer 
software; telecommunications; and electronic components, instruments and 
systems. Such companies are sensitive to foreign competition and import 
tariffs. Also, many products produced by companies in this sector may quickly 
become obsolete. 

(13) Transportation Sector: companies involved in the provision of 
transportation of people and products, such as: airlines, railroads and 
trucking firms. Revenues of companies in this sector will be affected by 
fluctuations in fuel prices resulting from domestic and international events, 
and government regulation of fares. 

(14) Utilities Sector: companies in the public utilities industry and 
companies deriving a substantial majority of their revenues through supplying 
public utilities such as: companies engaged in the manufacture, production, 
generation, 

                                      27 
<PAGE> 

transmission and sale of gas and electric energy; and companies engaged in 
the communications field, including telephone, telegraph, satellite, 
microwave and the provision of other communication facilities to the public. 
The gas and electric public utilities industries are subject to various 
uncertainties, including the outcome of political issues concerning the 
environment, prices of fuel for electric generation, availability of natural 
gas, and risks associated with the construction and operation of nuclear 
power facilities. 

(15) Foreign Sector: companies whose primary business activity takes place 
outside of the United States. The securities of foreign companies would be 
heavily influenced by the strength of national economies, inflation levels 
and the value of the U.S. dollar versus foreign currencies. Investments in 
the Foreign Sector will be subject to certain risks not generally associated 
with domestic investments. 

Diversified companies will generally be included in the sector of their 
predominant industry activity, as determined by the Adviser.

                                                                      APPENDIX B

                          DESCRIPTION OF BOND RATINGS

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

                        MOODY'S INVESTORS SERVICE, INC.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

                                      29 
<PAGE> 

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

                        STANDARD & POOR'S RATINGS GROUP

AAA: Debt rated 'AAA' has the highest rating assigned by S&P's. Capacity to 
pay interest and repay principal is extremely strong. 

AA: Debt rated 'AA' has a very strong capacity to pay interest and repay 
principal and differs from the higher rated issues only in small degree. 

A: Debt rated 'A' has a strong capacity to pay interest and repay principal 
although it is somewhat more susceptible to the adverse effects of changes in 
circumstances and economic conditions than debt in higher rated categories. 

BBB: Debt rated 'BBB' is regarded as having an adequate capacity to pay 
interest and repay principal. Whereas it normally exhibits adequate 
protection parameters, adverse economic conditions or changing circumstances 
are more likely to lead to a weakened capacity to pay interest and repay 
principal for debt in this category than in higher rated categories. 

BB: Debt rated 'BB' has less near-term vulnerability to default than other 
speculative issues. However, it faces major ongoing uncertainties or exposure 
to adverse business, financial, or economic conditions which could lead to 
inadequate capacity to meet timely interest and principal payments. The 'BB' 
rating category is also used for debt subordinated to senior debt that is 
assigned an actual or implied 'BBB-' rating. 

B: Debt rated 'B' has a greater vulnerability to default but currently has 
the capacity to meet interest payments and principal repayments. Adverse 
business, financial, or economic conditions will likely impair capacity or 
willingness to pay interest and repay principal. The 'B' rating category is 
also used for debt subordinated to senior debt that is assigned an actual or 
implied 'BB' or 'BB-' rating. 

CCC: Debt rated 'CCC' has a currently identifiable vulnerability to default, 
and is dependent upon favorable business, financial, and economic conditions 
to meet timely payment of interest and repayment of principal. In the event 
of adverse business, financial, or economic conditions, it is not likely to 
have the capacity to pay interest and repay principal. The 'CCC' rating 
category is also used for debt subordinated to senior debt that is assigned 
an actual or implied 'B' or 'B-' rating. 

CC: The rating 'CC' is typically applied to debt subordinated to senior debt 
that is assigned an actual or implied 'CCC' rating. 

C: The rating 'C' is typically applied to debt subordinated to senior debt 
which is assigned an actual or implied 'CCC-' debt rating. The 'C' rating may 
be used to cover a situation where a bankruptcy petition has been filed, but 
debt service payments are continued. 

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

D: Debt rated 'D' is in payment default. The 'D' rating category is used when 
interest payments or principal payments are not made on the date due even if 
the applicable grace period has not expired, unless S&P 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 if debt service payments 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 
categories. 

NR indicates that no public rating has been requested, that there is 
insufficient information on which to base a rating, or that S&P does not rate 
a particular type of obligation as a matter of policy.

               DESCRIPTION OF OBLIGATIONS ISSUED OR GUARANTEED BY
           U.S. GOVERNMENT AGENCIES, AUTHORITIES OR INSTRUMENTALITIES

U.S. Government Obligations--are issued by the Treasury and include bills, 
certificates of indebtedness, notes and bonds. Agencies and instrumentalities 
of the U.S. Government are established under the authority of an act of 
Congress and include, but are not limited to, the Tennessee Valley Authority, 
the bank for Cooperatives, the Farmers Home Administration, Federal Home Loan 
Banks, Federal Intermediate Credit Banks and Federal Land Banks, as well as 
those listed below. 

Federal Farm Credit Consolidated Systemwide Notes and Bonds--are bonds issued 
by a cooperatively owned nationwide system of banks and associations 
supervised by the Farm Credit Administration. These bonds are not guaranteed 
by the U.S. Government. 

Maritime Administration Bonds--are bonds issued by the Department of 
Transportation of the U.S. Government. 

FHA Debentures--are debentures issued by the Federal Housing Administration 
of the U.S. Government and are fully and unconditionally guaranteed by the 
U.S. Government. 

GNMA Certificates--are mortgage-backed securities, with timely payment 
guaranteed by the full faith and credit of the U.S. Government, which 
represent a partial ownership interest in a pool of mortgage loans issued by 
lenders such as mortgage bankers, commercial banks and savings and loan 
associations. Each mortgage loan included in the pool is also insured or 
guaranteed by the Federal Housing Administration, the Veterans Administration 
or the Farmers Home Administration. 

Federal Home Loan Mortgage Corporation Bonds--are bonds issued and guaranteed 
by the Federal Home Loan Mortgage Corporation and are not guaranteed by the 
U.S. Government. 

Federal Home Loan Bank Bonds--are bonds issued by the Federal Home Loan Bank 
System and are not guaranteed by the U.S. Government. 

Financing Corporation Bonds and Notes--are bonds and notes issued and 
guaranteed by the Financing Corporation. 

Federal National Mortgage Association Bonds--are bonds issued and guaranteed 
by the Federal National Mortgage Association and are not guaranteed by the 
U.S. Government. 

Resolution Funding Corporation Bonds and Notes--are bonds and notes issued 
and guaranteed by the Resolution Funding Corporation. 

Student Loan Marketing Association Debentures--are debentures backed by the 
Student Loan Marketing Association and are not guaranteed by the U.S. 
Government. 

Tennessee Valley Authority Bonds and Notes--are bonds and notes issued and 
guaranteed by the Tennessee Valley Authority. 

Some of the foregoing obligations, such as Treasury bills and GNMA 
pass-through certificates, are supported by the full faith and credit of the 
U.S. Government; others, such as securities of FNMA, by the right of the 
issuer to borrow from the U.S. Treasury; still others, such as bonds issued 
by SLMA, are supported only by the credit of the instrumentality. No 
assurance can be given that the U.S. Government will provide financial 
support to instrumentalities sponsored by the U.S. Government as it is not 
obligated by law, in certain instances, to do so. 

Although this list includes a description of the primary types of U.S. 
Government agency, authorities or instrumentality obligations in which the 
Fund intends to invest, the Fund may invest in obligations of U.S. Government 
agencies or instrumentalities other than those listed above.

<PAGE> 

                DESCRIPTION OF SHORT-TERM INVESTMENTS OTHER THAN
                          U.S. GOVERNMENT OBLIGATIONS

Certificates of Deposit--are certificates issued against funds deposited in a 
bank (including eligible foreign branches of U.S. banks), are for a definite 
period of time, earn a specified rate of return and are normally negotiable. 

Bankers' Acceptances--are marketable short-term credit instruments used to 
finance the import, export, transfer or storage of goods. They are termed 
"accepted" when a bank guarantees their payment at maturity. 

Commercial Paper--refers to promissory notes issued by corporations in order 
to finance their short-term credit needs. 

Corporate Obligations--include bonds and notes issued by corporations in 
order to finance long-term credit needs. 

A-1 and P-1 Commercial Paper Ratings 
Description of S&P and Moody's highest commercial paper ratings: 

The rating "A" is the highest commercial paper rating assigned by S&P, and 
issues so rated are regarded as having the greatest capacity for timely 
payment. Issues in the "A" category are delineated with the numbers 1, 2 and 
3 to indicate the relative degree of safety. The A-1 designation indicates 
that the degree of safety regarding timely payment is either overwhelming or 
very strong. Those A-1 issues determined to possess overwhelming safety 
characteristics will be denoted with a plus (+) sign designation. 

The rating P-1 is the highest commercial paper rating assigned by Moody's. 
Issuers rated P-1 have a superior ability for repayment. P-1 repayment 
capacity will normally be evidenced by the following characteristics: (1) 
leading market positions in well established industries; (2) high rates of 
return on funds employed; (3) conservative capitalization structure with 
moderate reliance on debt and ample asset protection; (4) broad margins in 
earnings coverage of fixed financial charges and high internal cash 
generation; and (5) well established access to a range of financial markets 
and assured sources of alternate liquidity.
