    SUPPLEMENT TO THE CURRENT STATEMENT OF ADDITIONAL INFORMATION

The following  information  supplements  the disclosure  found under the section
"Determination of Net Asset Value and Performance":

Historical Background:

The Fund was  established  by three  securities  executives - L. Sherman  Adams,
Charles H.  Learoyd  and Alston L. Carr.  The Fund began  operation  in 1924 and
established its own in-house research department in 1932. From 1932 to 1953, the
Fund was managed by Merrill  Griswold,  its  Chairman.  Mr.  Griswold  helped to
change the U.S. tax law in order to permit income and capital gains to be passed
along to mutual fund  shareholders  without a separate tax at the fund level. In
1936,  the Fund began  offering  shareholders  the ability to take  capital gain
distributions in cash or additional shares.  The Fund issued  shareholders full,
periodic  reports  disclosing  portfolio  holdings,  fees and  expenses a decade
before it was required to do so under the  Securities  Act of 1933,  as amended.
The Fund has been  actively  managed for the last 70 years  responding  to major
historical  events  which  have  affected  the stock  market  (such as the Great
Depression,  World War II, the post-war economic boom, the 1970s' oil crisis and
inflationary periods, and the "boom market" of the 1980s).

In 1969, the Fund's Trustees created a management  company,  MFS, to externalize
the investment  management  function and to permit the firm to offer  additional
funds.  MFS  introduced  several  mutual  funds in 1970 and  hired  the  current
chairman of MFS, A. Keith Brodkin, as a bond fund portfolio manager.

As of July 29, 1994, the Fund had total net assets of approximately $1.7 billion
and had approximately 89,451 shareholders.

From time to time, MFS Financial Services, Inc. ("FSI"), the Fund's distributor,
may, as appropriate, quote Fund-related comments from existing shareholders.

            THE DATE OF THIS SUPPLEMENT IS AUGUST 26, 1994

</TABLE>
                   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) of 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.

1. THE FUND
Massachusetts   Investors  Trust  (the  "Fund")  is  an  open-end,   diversified
management  investment  company  which was organized as a common law trust under
the laws of The Commonwealth of  Massachusetts  in 1924.  Shares of the Fund are
continuously  sold  to the  public,  and  the  Fund  uses  the  proceeds  to buy
securities (common stocks and other instruments) 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 a
distribution  fee and a 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 a  distribution  fee and a service fee which is greater than
the Class A  distribution  fee and service  fee.  Class B shares will convert to
Class A shares approximately eight years after purchase.

The Fund'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. A majority of the Trustees
are not  affiliated  with  the  Adviser.  The  Adviser  is  responsible  for the
management of the Fund's assets and the officers of the Fund are responsible for
its operations.  The Adviser manages the portfolio from day to day in accordance
with the Fund's investment objectives and policies. The selection of investments
and the way they are managed  depend on the conditions and trends in the economy
and the  financial  marketplaces.  The Fund also offers to buy back (redeem) its
shares from its shareholders at any time at net asset value, less any applicable
CDSC.

2. EXPENSE SUMMARY
SHAREHOLDER TRANSACTION EXPENSES:                      CLASS A      CLASS B
                                                       -------      -------
Maximum Initial Sales Charge Imposed on Purchases       
  of Fund Shares (as a percentage of offering price)    5.75%        0.00%
Maximum Contingent Deferred Sales Charge (as a
  percentage of original purchase price or
  redemption proceeds, as applicable)                See Below(1)    4.00%

ANNUAL OPERATING EXPENSES (AS A PERCENTAGE OF
AVERAGE NET ASSETS):(2)
  Management Fees                                       0.26%        0.26%
  Rule 12b-1 Fees (after applicable fee reduction)      0.20%(3)     1.00%(4)
  Other Expenses                                        0.22%        0.32%(5)
Total Operating Expenses                                0.68%        1.58%
- -----------
(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 A shares,  percentages  are based on expenses  incurred during the
    fiscal year ended December 31, 1993.  Percentages for Class B shares,  which
    were  initially  offered on September 7, 1993, are based on Class A expenses
    adjusted for Class B 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").    Currently,    0.10%   of   the
    distribution/service  fee is being  waived.  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  daily  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 A expenses incurred during the fiscal year ended December 31,
    1993,  except for the  shareholder  servicing  agent fee component of "Other
    Expenses".

EXAMPLE OF EXPENSES
An  investor  would pay the  following  dollar  amounts of  expenses on a $1,000
investment in the Fund,  assuming (a) 5% annual return and (b) redemption at the
end of each of the time periods indicated (unless otherwise noted):

PERIOD                                  CLASS A              CLASS B
 -----                                  -------              -------
                                                                          (1)
1 year .....................           $  64           $  56           $  16
3 years ....................              78              80              50
5 years ....................              93             106              86
10 years ...................             137             l64(2)          164(2)

(1) Assumes no redemption.
(2) Class B shares  convert to Class A shares  approximately  eight  years after
purchase; therefore, years nine and ten reflect Class A expenses.

     The  purpose  of  the  expense  table  above  is  to  assist  investors  in
understanding the various costs and expenses that a shareholder of the Fund will
bear  directly  or  indirectly.  More  complete  descriptions  of the  following
expenses are set forth in the following sections of the Prospectus:  (i) varying
sales charges on share purchases--"Purchases"; (ii) varying CDSCs-- "Purchases";
(iii)  management  fees--"  Investment  Adviser";  and (iv)  Rule  12b-1  (i.e.,
distribution plan) fees--"Distribution Plans".

     THE "EXAMPLE" SET FORTH ABOVE SHOULD NOT BE CONSIDERED A REPRESENTATION  OF
PAST OR FUTURE EXPENSES OF THE FUND; ACTUAL EXPENSES MAY BE GREATER OR LESS THAN
THOSE SHOWN.

4. INVESTMENT OBJECTIVES AND POLICIES

INVESTMENT  OBJECTIVES  -- The  Fund's  investment  objectives  are  to  provide
reasonable  current  income and  long-term  growth of capital  and  income.  Any
investment  involves  risk and  there  can be no  assurance  that the Fund  will
achieve its investment objectives.

INVESTMENT  POLICIES -- The Fund is believed to constitute a conservative medium
for that portion of an  investor's  capital  which he wishes to have invested in
securities  considered to be of high or improving  investment quality.  The term
"conservative  medium"  indicates  that the Fund attempts to exercise  prudence,
discretion and  intelligence in the selection of investments with due regard for
both probable income and probable safety of capital.  The words "high investment
quality"  reflect  the  intention  of the  Fund  to  avoid  the  acquisition  of
speculative  securities  or  those  of  doubtful  character  even  if  immediate
prospects are tempting.

The assets of the Fund are  normally  invested  in common  stocks or  securities
convertible into common stocks. However, the Fund may hold its assets in cash or
invest  in  commercial  paper,  repurchase  agreements  or  other  forms of debt
securities either to provide reserves for future purchases of common stock or as
a defensive measure in certain economic  environments.  Since shares of the Fund
represent  an  investment  in  securities   with   fluctuating   market  prices,
shareholders should understand that the value of shares of the Fund will vary as
the aggregate value of the Fund's portfolio  securities  increases or decreases.
Moreover, the amount of dividends the Fund pays to its shareholders will vary in
relation to the amount of  dividends  and interest  the Fund  receives  from its
portfolio securities.

FOREIGN SECURITIES: The Fund may invest up to 35% of its total assets in foreign
securities (not including American  Depositary  Receipts ("ADRs").  Investing in
securities of foreign issuers generally involves risks not ordinarily associated
with  investing in securities  of domestic  issuers.  These  include  changes in
currency rates,  exchange control  regulations,  governmental  administration or
economic or monetary policy (in the United States or abroad) or circumstances in
dealings between  nations.  Costs may be incurred in connection with conversions
between various currencies. Special considerations may also include more limited
information about foreign issuers,  higher brokerage costs, different accounting
standards and thinner trading markets.  Foreign  securities  markets may also be
less liquid,  more volatile and less subject to government  supervision  than in
the United States.  Investments in foreign  countries could be affected by other
factors   including   expropriation,   confiscatory   taxation   and   potential
difficulties  in  enforcing  contractual  obligations  and could be  subject  to
extended  settlement  periods.  The Fund may hold foreign  currency  received in
connection with  investments in foreign  securities when, in the judgment of the
Adviser,  it would be beneficial to convert such currency into U.S. dollars at a
later date, based on anticipated changes in the relevant exchange rate. The Fund
may also hold foreign currency in anticipation of purchasing foreign securities.
The Fund may invest in 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 collateral. Although ADRs are
issued by a U.S.  depository,  they are  subject to many of the risks of foreign
securities such as changes in exchange rates and more limited  information about
foreign  issuers.  See the  Statement  of  Additional  Information  for  further
discussion of foreign securities and the holding of foreign currency, as well as
the associated risks.

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 intended to minimize any risk.

RESTRICTED SECURITIES:  The Fund may purchase securities that are not registered
("restricted  securities")  under the  Securities  Act of 1933,  as amended (the
"1933 Act"),  but can be offered and sold to  "qualified  institutional  buyers"
under  Rule 144A under the 1933 Act ("Rule  144A").  However,  the Fund will not
invest  more than 15% of its net assets in  illiquid  investments, which include
repurchase   agreements   maturing  in  more  than  seven  days  and  restricted
securities,  unless the Board of Trustees  determines,  based upon a  continuing
review of the trading markets for the specific  restricted  security,  that such
restricted  securities are liquid.  The Board of Trustees has adopted guidelines
and  has  delegated  to the  Adviser  the  daily  function  of  determining  and
monitoring  liquidity of restricted  securities available pursuant to Rule 144A.
The Board, however,  retains sufficient oversight and is ultimately  responsible
for the  determinations.  Since it is not  possible  to predict  with  assurance
exactly how this market for Rule 144A restricted  securities  will develop,  the
Board  will  carefully  monitor  the  Fund's  investments  in these  securities,
focusing on such important factors, among others, as valuation,  liquidity,  and
availability of information. Investments in restricted securities could have the
effect of  increasing  the level of  illiquidity  in the Fund to the extent that
qualified  institutional  buyers  become for a time  uninterested  in purchasing
these restricted securities. 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.

"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 securities will
be delivered to the Fund at a future date usually  beyond  customary  settlement
time. In general,  the Fund does not pay for such securities  until received and
does not  start  earning  interest  or  dividends  on the  securities  until the
contractual  settlement date. In order to invest its assets  immediately,  while
awaiting delivery of securities  purchased on such bases, the Fund will normally
invest  in  cash,  short-term  money  market  instruments  and high  grade  debt
securities. See the Statement of Additional Information for a further discussion
of the nature of such transactions and risks associated therewith.

ZERO COUPON BONDS:  The Fund may also invest in securities which are convertible
into zero coupon bonds.  Zero coupon bonds are debt obligations which are issued
or  purchased  at  a  significant   discount  from  face  value.   The  discount
approximates  the total  amount of interest  the bonds will accrue and  compound
over the period until maturity, at a rate of interest reflecting the market rate
of the  security at the time of  issuance.  Zero coupon bonds do not require the
periodic payment of interest.  Such investments benefit the issuer by mitigating
its need for cash to meet debt service, but also require a higher rate of return
to  attract  investors  who are  willing to defer  receipt  of such  cash.  Such
investments may experience  greater volatility in market value due to changes in
interest rates than debt  obligations  which make regular  payments of interest.
The Fund will accrue income on such investments for tax and accounting purposes,
which is distributable to shareholders and which, because no cash is received at
the time of accrual,  may require the liquidation of other portfolio  securities
to satisfy the Fund's distribution obligations.

OPTIONS ON SECURITIES: The Fund may write (sell) covered put and call options on
securities and purchase put and call options on securities.  The Fund will write
such  options for the  purpose of  increasing  its return  and/or to protect the
value 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 a portfolio  security  in  connection  with
which the  option  may have been  written  or the  increased  cost of  portfolio
securities to be acquired.  In contrast,  however,  if the price of the security
underlying the option moves adversely to the Fund's position,  the option may be
exercised  and the Fund will be required  to purchase or sell the  security at a
disadvantageous price, resulting in losses 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.

The Fund may  purchase put or call  options in  anticipation  of declines in the
value of portfolio  securities  or increases  in the value of  securities  to be
acquired.  In the event that such declines or increases  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 risk assumed by the Fund in connection
with such  transactions  is  limited to the amount of the  premium  and  related
transaction costs associated with the option,  although the Fund may be required
to forfeit  such amounts in the event that the prices of  securities  underlying
the options do not move in the direction or to the extent anticipated.

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,  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.  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.

OPTIONS ON FOREIGN  CURRENCIES:  The Fund may also purchase and write options on
foreign  currencies  ("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 may 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 paid for
the option plus related  transaction  costs.  The Fund may also choose to, or be
required to, receive delivery of the foreign  currencies  underlying  Options on
Foreign  Currencies it has entered into.  Under certain  circumstances,  such as
where the Adviser  believes that the applicable  exchange rate is unfavorable at
the time the currencies are received or the Adviser  anticipates,  for any other
reason,  that the exchange rate will improve,  the Fund may hold such currencies
for  an   indefinite   period   of  time.   See   "Investment   Objectives   and
Policies--Foreign  Securities"  in the Statement of Additional  Information  for
information on the risks associated with holding foreign currency.

FUTURES  CONTRACTS:  The Fund may enter into stock  index and  foreign  currency
futures contracts  (collectively "Futures Contracts").  Such transactions may be
entered  into for hedging  purposes,  in order to protect the Fund's  current or
intended  investments  from the effects of changes in exchange rates or declines
in the stock market, and for non-hedging purposes subject to applicable law. The
Fund will incur  brokerage  fees when it purchases and sells Futures  Contracts,
and will be required to maintain margin deposits. In addition, Futures Contracts
entail  risks.  Although the Adviser  believes that use of such  contracts  will
benefit the Fund,  if its  investment  judgment  about the general  direction of
exchange rates or the stock market is incorrect,  the Fund's overall performance
may be poorer than if it had not entered into any such contract and the Fund may
realize a loss. The Fund will not enter into any Futures Contract if immediately
thereafter the value of all such Futures Contracts would exceed 50% of the value
of its total assets.

OPTIONS ON FUTURES CONTRACTS: The Fund may purchase and write options on Futures
Contracts  ("Options on Futures Contracts") in order to protect against declines
in the  values of  portfolio  securities  or  against  increases  in the cost of
securities to be acquired and for  non-hedging  purposes,  subject to applicable
law, which  involves  greater risk and may result in losses which are not offset
by gains on other portfolio  assets.  Purchases of Options on Futures  Contracts
may present less risk in hedging the Fund's  portfolio 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,  although  it may be
necessary  to exercise  the option to realize any profit,  which  results in the
establishment  of  a  futures  position.  The  writing  of  Options  on  Futures
Contracts,  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.

In order to assure that the Fund will not be deemed to be a "commodity pool" for
purposes of the Commodity  Exchange Act,  regulations  of the Commodity  Futures
Trading Commission (the require that the Fund enter into transactions in Futures
Contracts  and  Options  on  Futures  Contracts  only (i) for bona fide  hedging
purposes (as defined in CFTC  regulations),  or (ii) for  non-hedging  purposes,
provided  that the  aggregate  initial  margin and premiums on such  non-hedging
positions does not exceed 5% of the liquidation  value of the Fund's assets.  In
addition, the Fund must comply with the requirements of various state securities
laws in connection with such transactions.

FORWARD  CONTRACTS:  The Fund may enter into forward foreign  currency  exchange
contracts for the purchase or sale of a fixed quantity of a foreign  currency at
a future date ("Forward  Contracts").  The Fund may enter into Forward Contracts
for hedging  purposes as well as for  non-hedging  purposes  (i.e.,  speculative
purposes).  By entering  into  transactions  in Forward  Contracts,  for hedging
purposes,  the Fund may be  required  to forego  the  benefits  of  advantageous
changes in exchange rates and, in the case of Forward Contracts entered into for
non-hedging  purposes,  the Fund may sustain  losses which will reduce its gross
income. Such transactions,  therefore, could be considered speculative.  Forward
Contracts  are  traded  over-the-counter  and not on  organized  commodities  or
securities  exchanges.  As a  result,  Forward  Contracts  operate  in a  manner
distinct from exchange-traded  instruments, and their use involves certain risks
beyond those associated with transactions in Futures Contracts or options traded
on exchanges. The Fund may choose to, or be required to, receive delivery of the
foreign  currencies  underlying  Forward  Contracts it has entered  into.  Under
certain  circumstances,  such as where the Adviser  believes that the applicable
exchange  rate is  unfavorable  at the time the  currencies  are received or the
Adviser anticipates,  for any other reason, that the exchange rate will improve,
the Fund may hold such currencies for an indefinite period of time. The Fund may
also enter into a Forward Contract on one currency to hedge against risk of loss
arising from  fluctuations in the value of a second  currency  (referred to as a
"cross  hedge")  if, in the  judgment of the  Adviser,  a  reasonable  degree of
correlation  can be  expected  between  movements  in  the  values  of  the  two
currencies.  The Fund has established  procedures  consistent with statements of
the SEC and its staff  regarding  the use of  Forward  Contracts  by  registered
investment companies,  which requires the use of segregated assets or "cover" in
connection  with  the  purchase  and  sale of such  contracts.  See  "Investment
Objective  and  Policies--Foreign  Securities"  in the  Statement of  Additional
Information  for  information  on the  risks  associated  with  holding  foreign
currency.

RISKS OF OPTIONS,  FUTURES  CONTRACTS AND FORWARD  CONTRACTS:  Although the Fund
will enter into certain transactions in options,  Futures Contracts,  Options on
Futures  Contracts,  Forward  Contracts  and Options on Foreign  Currencies  for
hedging  purposes,  such  transactions  nevertheless  involve certain risks. For
example,  a lack of correlation  between the instrument  underlying an option or
Futures  Contract and the assets  being  hedged,  or  unexpected  adverse  price
movements,  could  render the Fund's  hedging  strategy  unsuccessful  and could
result in losses.  The Fund also may enter into transactions in such instruments
for other than hedging  purposes,  subject to  applicable  law,  which  involves
greater risk. In particular, such transactions may result in losses for the Fund
which are not offset by gains on other  portfolio  positions,  thereby  reducing
gross income.  In addition,  foreign currency markets may be extremely  volatile
from time to time. There also 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.
The Statement of Additional Information contains a description of the nature and
trading mechanics of options,  Futures Contracts,  Options on Futures Contracts,
Forward Contracts and Options on Foreign  Currencies,  and includes a discussion
of the risks related to transactions therein.

Transactions   in  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 and on foreign  exchanges.  In addition,  the  securities  underlying
options,  Futures  Contracts and Options on Futures Contracts traded by the Fund
will include both domestic and foreign securities.

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 the other  investment
company clients of MFS Financial Services, Inc., the Fund's distributor ("FSI"),
as a factor in the selection of  broker-dealers  to execute the Fund's portfolio
transactions.  For a further  discussion of portfolio  trading,  see  "Portfolio
Transactions   and  Brokerage   Commissions"  in  the  Statement  of  Additional
Information.

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

The investment  objectives and policies  described above are not fundamental and
may be changed without shareholder approval.

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  and policies are
adhered to at the time of purchase or utilization of assets; a subsequent change
in circumstances will not be considered to result in a violation of policy.

5. MANAGEMENT OF THE FUND
INVESTMENT  ADVISER -- The Adviser  manages the Fund  pursuant to an  Investment
Advisory Agreement,  dated May 20, 1982 (the "Advisory Agreement").  The Adviser
provides the Fund with overall investment advisory and administrative  services,
as well as general office facilities. Kevin R. Parke, a Senior Vice President of
the Adviser, and John D. Laupheimer,  Jr., a Vice President of the Adviser, have
been the Fund's  portfolio  managers since 1992. Amy W. deRham, a Vice President
of the  Adviser,  has also been a portfolio  manager of the Fund since  January,
1994. Mr. Parke has been employed by the Adviser since 1985. Ms. deRham has been
employed by the Adviser  since 1986.  Mr.  Laupheimer  has been  employed by the
Adviser since 1981. Subject to such policies as the Trustees may determine,  the
Adviser  makes  investment  decisions  for the  Fund.  For  these  services  and
facilities,  the Adviser receives a management fee, computed and paid monthly on
the basis of a formula based upon a percentage  of the Fund's  average daily net
assets plus a percentage  of the Fund's gross  income  (i.e.,  income other than
gains from the sale of securities),  in each case on an annualized basis for the
Fund's  then-current  fiscal year.  The  applicable  percentages  are reduced as
assets and income reach the following levels:
<PAGE>

ANNUAL RATE OF MANAGEMENT FEE                      ANNUAL RATE OF MANAGEMENT FEE
BASED ON AVERAGE DAILY NET ASSETS                      BASED ON GROSS INCOME
- ---------------------------------                   ----------------------------
0.30% of the first $200 million                    6.67% of the first $6 million
0.24% of the next $300 million                     5.33% of the next $9 million
0.12% of average daily net assets                  2.67% of gross income in
      in excess of $500 million                          excess of $15 million

For the Fund's fiscal year ended December 31, 1993, MFS received management fees
under the Advisory  Agreement of $4,680,789  (of which  $2,672,542  was based on
average  daily net assets and  $2,008,247  on gross  income),  equivalent  on an
annualized  basis  to  0.29%  of  the  Fund's  average  daily  net  assets.  MFS
voluntarily  waived $407,175 of its management fee,  equivalent on an annualized
basis to 0.03% of the Fund's average daily net assets.

The Advisory  Agreement  provides that the  compensation  of the Adviser will be
reduced by an annual sum  representing the Fund's share of the fair value of the
use of office furniture, furnishings and equipment purchased over the years with
funds  furnished by the Fund and  Massachusetts  Investors  Growth Stock Fund as
part of shared  expenses.  The total  annual use value of this  property for the
period  ending  December  31,  1993 has been  determined  pursuant  to a formula
devised by an independent supplier to be $80,037.26,  and this determination has
been  approved by the Trustees  who are not  affiliated  with the Adviser.  This
amount and  amounts so  determined  and  approved  in  subsequent  years will be
credited 24% to  Massachusetts  Investors Growth Stock Fund and 76% to the Fund,
being the average of their  proportionate  contributions to shared expenses over
the ten-year period ended December 31, 1968.

MFS also  serves as  investment  adviser  to each of the other  funds in the MFS
Family of Funds  (the  "MFS  Funds"),  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 Variable Insurance 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 MFS, 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 Fund as the first mutual fund in the United  States.  Net assets
under the management of the MFS organization were approximately $33.6 billion on
behalf of approximately  1.4 million investor accounts as of March 31, 1994. 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 R. Gardner and John D.
McNeil.  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  company,  is one of the  largest  international  life
insurance  companies  and has been  operating  is the United  States since 1895,
establishing a headquarters  office here in 1973. The executive  officers of MFS
report to the Chairman of Sun Life.

6. 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 per share plus an
initial sales charge (or CDSC in the case of certain  purchases of $1 million or
more) as follows:

</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,  al the rate of 1% of the  lesser  of the  value of the  shares
redeemed  (exclusive of reinvested  dividends and capital gain  distributions or
the total cost of such shares.

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 that 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 which it intends to apply for the benefit of the Fund.

FSI allows  discounts  to dealers  (which  are alike for all  dealers)  from the
applicable  public  offering  price, as shown in the above table. 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  other MFS Funds  owned or
being  purchased,  the existence of an agreement to purchase  additional  shares
during a 13-month  period (or a 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,  on behalf of the Fund and  pursuant  to the Fund's  Class A
Distribution  Plan,  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  Fund,  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 persons 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 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 employees or representatives 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.  Insurance  company  separate  accounts may purchase  Class A
shares of the Fund at their net asset value. 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  of the  Fund  may be  sold at net  asset  value  in
connection with the acquisition or liquidation of the assets of other investment
companies or personal holding companies.  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 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.

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 sold  at net  asset  value  through  the  automatic
reinvestment  of Class A and Class B  distributions  which  constitute  required
withdrawals from qualified retirement plans. 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"). 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).

CLASS B SHARES: Class B shares are offered at net asset value without an initial
sales charge but subject to a CDSC as follows:

       YEAR OF                  CONTINGENT
     REDEMPTION               DETERRED SALES
   AFTER PURCHASE                 CHARGE

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

* Class B shares  purchased  from  January 1, 1993  through  August 31, 1993 are
  subject  to a CDSC of 5% in the event of a  redemption  within  the first year
  after purchase.

For Class B shares  purchased  prior to January 1, 1993, the Fund imposes a CDSC
as a percentage of redemption proceeds as follows:

       YEAR OF                 CONTINGENT
     REDEMPTION              DETERRED SALES
   AFTER PURCHASE                CHANGE
   --------------            --------------
     First                         6%
     Second                        5%
     Third                         4%
     Fourth                        3%
     Fifth                         2%
     Sixth                         1%
     Seventh and following         0%


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
Sections  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 loan from the plan
(repayments  of loans,  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  Section  1.401(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  redemption  by (i) officers
of the Fund,  (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 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  Code  (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 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 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  taxable  events 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 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.

Purchases and exchanges  should be made for  investment  purposes only. 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 any  purchases by a particular  purchaser
or group,  for example,  when such purchase is contrary to the best interests of
the Fund's other  shareholders  or otherwise would disrupt the management of the
Fund.

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 is 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.

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 an 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 timers special  procedures,  privileges and
restrictions with respect to exchanges may apply to market timers who enter into
an agreement with FSI, as set forth in such agreement (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 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.  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 a 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 described above 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 the
Exchange is restricted,  or, to the extent otherwise  permitted by 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
their 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. 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.

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 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 share 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 securities
(instead of cash) from the Fund's portfolio.  The securities distributed in such
a  distribution  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 when 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 Exchange 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  in  Class A or Class B shares
("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  basses  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  of the Fund  purchased  prior to  January  1,  1993,
transactions  will be  aggregated on a calendar  year basses  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 the rough 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 the  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 a CDSC will be  unaffected  by  exchanges or transfers of
registration.

DISTRIBUTION PLANS
The Trustees have adopted  separate  distribution  plans for Class A and Class B
shares 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 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 with respect to 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 may 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. FSI, however,
is  currently  waiving  this 0.10%  distribution  fee and will not in the future
accept  payment of this fee unless it first  obtains the  approval of the Fund's
Board  of  Trustees.  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%  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% 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"  above),  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 distribution 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  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  to its  shareholders  substantially  all of its  net
investment  income as dividends on a quarterly  basis.  In  determining  the net
investment income available for distributions,  the Fund may rely on projections
of its  anticipated  net investment  income over a longer term,  rather than its
actual net investment income for the period. In addition,  the Fund may make one
or more  distributions  during the calendar  year to its  shareholders  from any
long-term  capital  gains  and 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 with  respect  to which a  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
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 expected that
the Fund will not be required to pay entity-level federal income or excise taxes
although  foreign-source  income  received 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 or 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 gains
distributions)   may   qualify   for  the   dividends-received   deduction   for
corporations.  A  statement  setting  forth  the  federal  income  status of all
dividends and  distributions  for that year,  including  the portion  taxable as
ordinary  income,  any portion taxable as long-term  capital gains,  any portion
representing  a return of capital  (which is generally free of current taxes but
results in 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 payments at the rate of 30%
on dividends and other  payments that are subject to such  withholding  and that
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. However, backup withholding 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  advisers  as to the  tax  consequences  to  them 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 the  Exchange by  deducting  the
amount of the liabilities attributable to the class from the value of the Fund's
assets  attributable  to the class and dividing the  difference by the number of
shares of the class  outstanding.  Equity securities in the Fund's portfolio are
valued at their market value.  For a discussion of the manner in which values of
these and other assets in the Fund's portfolio are determined, see the Statement
of Additional Information. The net asset value per share 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 has two  classes  of  shares,  entitled  Class A and  Class B Shares of
Beneficial  Interest.  The Trustees  have fixed the par value at  $0.33-1/3  per
share. The Fund has reserved the right to create and issue additional classes of
shares, in which case each class of shares of the Fund would participate equally
in the earnings,  dividends and assets  attributable  to that class of shares of
the Fund. Shareholders are entitled to one vote for each share held and may vote
in the  election  of  Trustees  and on other  matters  submitted  to meetings of
shareholders.  Each  class of shares of the Fund  will  vote  separately  on any
material increase in the fees under its Distribution Plan or on any other matter
that solely affects that class of shares,  but will otherwise vote together with
all other classes of shares of the Fund on all other matters.  The Fund does not
intend to hold annual meetings.  The Fund's Declaration of Trust provides that a
Trustee may be removed from office in certain instances.

Each share of a class  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  in
"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 Declaration of Trust has no provision for annual meetings.  New Trustees are
appointed  by the  remaining  Trustees  (not the  shareholders)  subject  to the
written  assent  of more  than 50% of the  shares  voting  on each  appointment.
Shareholders  therefore have limited non-cumulative voting rights and holders of
more than 50% of the shares voting may accept or reject each  appointment  while
holders of less than 50% are not able to reject any  appointment.  Amendments to
the Declaration of Trust require written consent of the holders of a majority of
the shares. The 1940 Act confers additional voting rights on the shareholders.

PERFORMANCE INFORMATION
From time to time, the Fund will provide yield,  current  distribution  rate and
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. All
performance  quotations are based on historical performance and are not intended
to indicate future  performance.  Yield calculations are based on the annualized
net  investment  income  per share  allocated  to each  class of the Fund over a
30-day period stated as a percent of the maximum  public  offering price of that
class on the last day of that  period.  Yield  calculations  for  Class B shares
assume  no CDSC is  paid.  The  current  distribution  rate  for  each  class is
generally based upon the total amount of dividends per share paid by the Fund to
shareholders  of that class  during the past  twelve  months and is  computed by
dividing the amount of such  dividends by the maximum  public  offering price of
that class at the end of such period. Current distribution rate calculations for
Class B shares  assume no CDSC is paid.  The current  distribution  rate differs
from the yield calculation because it may include  distributions to shareholders
from sources  other than  dividends and  interest,  such as premium  income from
option writing, short-term capital gains, and return of invested capital, and is
calculated over a different period of time. 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 the 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.  Total rate of
return  reflects all  components of investment  over a stated period of time and
current  distribution  rate reflects only the rate of distributions  paid by the
Fund over a stated period of time. All  performance  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 yield, current distribution rate and 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 holdings available to investors upon request.

7. 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;

    -- 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  gains
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 either  class of the Fund or any of the classes of other MFS Funds or,
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 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 all classes of shares of
that  shareholder  in the  MFS  Funds  or 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 any other MFS Fund. Furthermore,  distributions made by the Fund may be
automatically  invested at net asset value (and without any applicable  CDSC) in
shares  of the same  class of  another  MFS  Fund,  if  shares  of such Fund are
available for sale.

     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
(a "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 exchange their shares for the same class of shares of
the other MFS Funds under the Automatic  Exchange Plan.  The Automatic  Exchange
Plan  provides for  automatic  monthly or quarterly  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
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.
