                      SUPPLEMENT TO THE CURRENT PROSPECTUS

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

          FSI may enter into an agreement with  shareholders  who intend to make
          exchanges among certain classes of certain MFS Funds (as determined by
          FSI) which follow a timing pattern,  and with  individuals or entities
          acting on such shareholders' behalf  (collectively,  "market timers"),
          setting forth the terms,  procedures and restrictions  with respect to
          such exchanges.  In the absence of such an agreement, it 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.

                  THE DATE OF THIS SUPPLEMENT IS APRIL 1,1994.

</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
MFS Capital Growth Fund (the "Fund") is a diversified series of MFS Series Trust
II (the "Trust"),  an open-end management investment company which was organized
as a business trust under the laws of The  Commonwealth of Massachusetts on July
30, 1986. The Trust presently  consists of four series of shares,  each of which
represents a portfolio with separate investment policies. Shares of the Fund are
continuously  sold to the  public  and the Fund  then uses the  proceeds  to buy
securities  for its  portfolio.  Two classes of shares of the Fund currently are
offered to the  general  public.  Class A shares are  offered at net asset value
plus an initial sales charge (or a contingent  deferred  sales charge (a "CDSC")
in the case of  certain  purchases  of $1  million  or more)  and  subject  to a
Distribution  Plan,  providing for a distribution fee and a service fee. Class B
shares are  offered at net asset value  without a sales  charge but subject to a
CDSC and a Distribution  Plan providing for a distribution fee and a service fee
which are 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 Trust's Board of Trustees provides broad supervision over the affairs of the
Fund. Massachusetts Financial Services Company, a Delaware corporation ("MFS" or
the "Adviser"),  is the Fund's investment  adviser.  Prior to September 1, 1993,
Lifetime  Advisers,  Inc.  ("LAI"),  a Delaware  corporation  and a wholly owned
subsidiary  of MFS,  was the  investment  adviser  for the Fund.  The Adviser is
responsible  for the  management  of the Fund's  assets and the  officers of the
Trust are  responsible  for the  Fund's  operations.  The  Adviser  manages  the
portfolio from day to day in accordance with the Fund's investment objective and
policies.  A majority of the Trustees are not affiliated  with the Adviser.  The
selection of  investments  and the way they are managed depend on the conditions
and  trends in the  economies  of the  various  countries  of the  world,  their
financial  markets and the  relationship of their currencies to the U.S. dollar.
The  Trust  also  offers  to buy back  (redeem)  shares  of the Fund  from  Fund
shareholders at any time at net asset value, less any applicable CDSC.

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%(2)
ANNUAL OPERATING EXPENSES
  (AS A PERCENTAGE OF AVERAGE NET ASSETS):(3)
    Management Fees ...................        0.75%              0.75%
    Rule 12b-1 Fees (after applicable
      fee reduction)...................        0.00%(4)           1.00%(5)
    Other Expenses.....................        0.33%(6)           0.40%(7)
    Total Operating Expenses (after 
      applicable fee reduction)(8).....        1.08%              2.15%

(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) Shares  purchased on or after January 1, 1993 but prior to September 1, 1993
    will be  subject  to a CDSC of 5% in the event of a  redemption  within  the
    first year after purchase.

(3) For Class B shares,  percentages  are based on expenses  incurred during the
    fiscal  year  ended  November  30,  1993.  For  Class A shares,  which  were
    initially  offered on  September 7, 1993,  percentages  are based on Class B
    expenses adjusted for Class A specific expenses.

(4) 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.  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.  Rule 12b-1 fees will become  payable by the Fund when
    the Fund's net assets  attributable  to Class A shares first equal or exceed
    $40,000,000,  at which time the Fund's distributor  intends to waive payment
    of 0.10%  payable  under the Class A  Distribution  Plan (see  "Distribution
    Plans").

(5) 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.

(6) Based on Class B expenses  incurred  during its last  fiscal year except for
    the shareholder servicing agent fees component of "Other Expenses" which has
    been estimated for Class A.

(7) Based on current shareholder servicing agent fees.

(8) Absent any reductions,  "Total Operating Expenses" would have been 1.43% for
    Class A shares.

                             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 ........     $ 68       $ 62          $ 22
          3 years .......       90         97            67
          5 years .......      114        135           115
          10 years ......      182        221(2)        221(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 Fund expenses are set
forth in the following sections: (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 OBJECTIVE AND POLICIES

The Fund seeks to provide  growth of  capital.  Dividend  income,  if any,  is a
consideration  incidental  to the  Fund's  objective  of growth of  capital.  In
seeking to achieve  its  investment  objective,  the Fund  maintains  a flexible
approach  toward types of companies  as well as types of  securities,  depending
upon the economic  environment  and the relative  attractiveness  of the various
securities  markets.  Generally,  emphasis is placed upon companies  believed to
possess  above-average  growth  opportunities rather than on companies with more
mature  growth  trends.  However,  mature  companies  are included  when, in the
judgment of the Adviser,  the relative  evaluation of such companies  appears to
provide opportunities for appreciation, or when mature companies are expected to
undergo an acceleration in growth of earnings because of special factors such as
new management,  new products,  changes in consumer demand,  or basic changes in
the economic environment.

While the policy of the Fund is to invest  primarily  in common  stocks,  it may
seek  appreciation in other types of securities such as fixed income  securities
(which may be unrated),  convertible  bonds,  convertible  preferred  stocks and
warrants when relative values make such purchases  appear  attractive  either as
individual issues or as types of securities in certain economic environments. It
is contemplated that the Fund's non-convertible  long-term debt investments will
consist  primarily  of  "investment  grade"  securities  (rated  at least Baa by
Moody's Investors  Service Inc.  ("Moody's") or BBB by Standard & Poor's Ratings
Group ("S&P")) and that the convertible debt investments will consist  primarily
of securities rated at least Ba by Moody's or BB by S&P. Securities rated BBB by
S&P or Baa by  Moody's  are  considered  to  have  speculative  characteristics.
Securities  rated BB by S&P or Ba by Moody's are considered  speculative and are
commonly known as "junk bonds".  (See  "Additional  Information as to Investment
Objective and Policies -- Risk Factors  Regarding Lower Rated  Securities" below
for a  further  description  of the risks  associated  with  investing  in these
securities.)  For a  description  of  these  ratings,  see  Appendix  A to  this
Prospectus.

The Fund may also  invest up to 25% of its total  assets in  foreign  securities
(not including American  Depositary  Receipts  ("ADRs"),  which may be traded on
foreign  exchanges.  The Fund may  also  enter  into  forward  foreign  currency
exchange  contracts for the purchase or sale of foreign currency for hedging and
non-hedging  purposes,  including  transactions  entered into for the purpose of
profiting from anticipated changes in foreign currency rates, as well as options
on foreign  currencies  (see  "Investment  Techniques  -- Forward  Contracts  on
Foreign Currency" and "-- Options on Foreign  Currencies"  below).  The Fund may
also hold foreign currency (see "Additional Risk Factors" below).

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 exchange  rates and more limited  information  about foreign
issuers (see "Additional Risk Factors" below).

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

There is no formula as to the  percentage  of assets that may be invested in any
one type of security.  Cash,  short-term  obligations,  repurchase agreements or
other  forms of debt  securities  are  held to  provide  a  reserve  for  future
purchases  of common  stock or other  securities.  Subject to tax  requirements,
portfolio  changes are made without  regard to the length of time a security has
been held, or whether a sale would result in a profit or loss.

ADDITIONAL INFORMATION AS TO INVESTMENT OBJECTIVE AND POLICIES
FIXED INCOME  SECURITIES -- When and if available,  the Fund may purchase  fixed
income  securities  at a discount  from face value.  However,  the Fund does not
intend  to hold  such  securities  to  maturity  for the  purpose  of  achieving
potential  capital  gains,  unless  current  yields on these  securities  remain
attractive.

RISK  FACTORS  REGARDING  LOWER  RATED  SECURITIES  -- The Fund may  invest to a
limited  extent in lower rated fixed income  securities  or  comparable  unrated
securities.  Investments  in fixed income  securities  offering the high current
income  sought  by the  Fund,  while  generally  providing  greater  income  and
opportunity for gain than investments in higher rated securities, usually entail
greater risk of principal and income  (including  the  possibility of default or
bankruptcy of the issuers of such securities), and involve greater volatility of
price  (especially  during  periods of  economic  uncertainty  or  change)  than
investments in higher rated securities and because yields may vary over time, no
specified level of income can ever be assured.  In particular,  securities rated
lower  than  Baa by  Moody's  or BBB by  S&P or  comparable  unrated  securities
(commonly known as "junk bonds") are considered  speculative.  These lower rated
high yielding fixed income securities generally tend to reflect economic changes
(and the  outlook  for  economic  growth),  short-term  corporate  and  industry
developments  and the market's  perception of their credit  quality  (especially
during  times of  adverse  publicity)  to a greater  extent  than  higher  rated
securities  which  react  primarily  to  fluctuations  in the  general  level of
interest  rates  (although  these lower rated fixed income  securities  are also
affected by changes in interest rates).  In the past,  economic  downturns or an
increase  in interest  rates have under  certain  circumstances  caused a higher
incidence  of default by the  issuers of these  securities  and may do so in the
future,  especially  in the case of highly  leveraged  issuers.  During  certain
periods,  the higher yields on the Fund's lower rated high yielding fixed income
securities are paid primarily because of the increased risk of loss of principal
and income,  arising from such factors as the heightened  possibility of default
or  bankruptcy  of the  issuers  of such  securities.  Due to the  fixed  income
payments of these  securities,  the Fund may  continue to earn the same level of
interest  income while its net asset value  declines  due to  portfolio  losses,
which could result in an increase in the Fund's yield despite the actual loss of
principal.  The prices for these  securities may be affected by legislative  and
regulatory  developments.  For example,  federal  rules require that savings and
loan associations gradually reduce their holdings of high-yield  securities.  An
effect of such  legislation  may be to depress the prices of  outstanding  lower
rated high yielding fixed income securities.  Changes in the value of securities
subsequent to their acquisition will not affect cash income or yield to maturity
to the Fund but will be  reflected in the net asset value of shares of the Fund.
The market for these lower rated fixed income securities may be less liquid than
the market for  investment  grade  fixed  income  securities.  Furthermore,  the
liquidity  of these lower  rated  securities  may be  affected  by the  market's
perception of their credit  quality.  Therefore,  the Adviser's  judgment may at
times  play a  greater  role in  valuing  these  securities  than in the case of
investment  grade fixed  income  securities,  and it also may be more  difficult
during  times of certain  adverse  market  conditions  to sell these lower rated
securities  at their fair  value to meet  redemption  requests  or to respond to
changes in the  market.  No minimum  rating  standard  is  required by the Fund,
although  it is  contemplated  that the Fund's  non-convertible  long-term  debt
investments will consist  primarily of "investment  grade"  securities (rated at
least Baa by Moody's or BBB by S&P) (see  "Investment  Objective  and  Policies"
above).  To the  extent the Fund  invests  in these  lower  rated  fixed  income
securities, the achievement of its investment objective may be more dependent on
the Adviser's own credit  analysis than in the case of fund  investing in higher
quality  bonds.  While the  Adviser may refer to ratings  issued by  established
credit rating  agencies,  it is not a policy of the Fund to rely  exclusively on
ratings issued by these agencies, but rather to supplement such ratings with the
Adviser's own independent and ongoing review of credit quality.

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

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

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

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

Investing in foreign  securities  or on foreign  exchanges may present a greater
degree of risk than investing in domestic  issuers.  These risks include changes
in currency rates,  exchange control regulations,  governmental  administration,
economic or monetary policy (in this country or abroad),  war or  expropriation.
In  particular,  the dollar value of portfolio  securities  of non-U.S.  issuers
fluctuates  with  changes  in market  and  economic  conditions  abroad and with
changes in relative  currency values (when the value of the dollar  increases as
compared  to a  foreign  currency,  the  dollar  value of a  foreign-denominated
security  decreases,  and vice versa).  Costs may be incurred in connection with
conversions between various currencies.  Special considerations may also include
more  limited  information  about  foreign  issuers,   higher  brokerage  costs,
different accounting  standards and thinner trading markets.  Foreign securities
markets may also be less liquid,  more  volatile and less subject to  government
supervision than in the United States. Investments in foreign countries could be
affected  by  other  factors  including   confiscatory  taxation  and  potential
difficulties  in  enforcing  contractual  obligations  and could be  subject  to
extended settlement periods.  Therefore, an investment in shares of the Fund may
be  subject to a greater  degree of risk than  investments  in other  investment
companies which invest exclusively in domestic securities.

As a result of its  investments  in  foreign  securities,  the Fund may  receive
interest or dividend payments, or the proceeds of the sale or redemption of such
securities,  in the foreign currencies in which such securities are denominated.
In that event, the Fund may promptly convert such currencies into dollars at the
then current exchange rate. Under certain circumstances,  however, such as where
the Adviser  believes that the  applicable  exchange rate is  unfavorable at the
time the  currencies  are  received  or the Adviser  anticipates,  for any other
reason,  that the exchange rate will improve,  the Fund may hold such currencies
for an indefinite period of time.

In  addition,  the Fund may be  required  to  receive  delivery  of the  foreign
currency underlying forward foreign currency contracts it has entered into. This
could occur,  for example,  if an option written by the Fund is exercised or the
Fund is unable to close out a forward contract it has entered into. The Fund may
also hold foreign currency in anticipation of purchasing foreign securities. The
Fund may also elect to take  delivery of the  currencies  underlying  options or
forward contracts if, in the judgment of the Adviser, it is in the best interest
of the Fund to do so. In such instances as well,  the Fund may promptly  convert
the foreign currencies to dollars at the then current exchange rate, or may hold
such currencies for an indefinite period of time.

While the  holding  of  currencies  will  permit the Fund to take  advantage  of
favorable movements in the applicable exchange rate, it also exposes the Fund to
risk of loss if such rates move in a direction  adverse to the Fund's  position.
Such losses  could  reduce any profits or increase  any losses  sustained by the
Fund from the sale or  redemption  of  securities,  and could  reduce the dollar
value of interest of  securities,  and could reduce the dollar value of interest
or dividend  payments  received.  In addition,  the holding of currencies  could
adversely  affect  the  Fund's  profit or loss on  currency  options  or forward
contracts, as well as its hedging strategies.

See the Statement of Additional  Information  for further  discussion of foreign
securities and the holding of foreign currency as well as the associated risks.

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

SHORT-TERM  INVESTMENTS  FOR  DEFENSIVE  PURPOSES  -- During  periods of unusual
market  conditions  when the  Adviser  believes  that  investing  for  defensive
purposes is appropriate,  or in order to meet anticipated redemption requests, a
large  portion or all of the assets of the Fund may be  invested in cash or cash
equivalents  including,  but not limited  to,  obligations  of banks  (including
certificates of deposit,  bankers'  acceptances and repurchase  agreements) with
assets of $1 billion or more,  commercial paper,  short-term notes,  obligations
issued or guaranteed by the U.S. Government or any of its agencies,  authorities
or  instrumentalities  and  related  repurchase   agreements.   U.S.  Government
securities  also  include  interests  in trusts or other  entities  representing
interests in obligations  that are issued or guaranteed by the U.S.  Government,
its  agencies,  authorities  or  instrumentalities.   See  Appendix  B  to  this
Prospectus  for  a  description  of  U.S.  Government  obligations  and  certain
short-term investments.

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

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

RESTRICTED  SECURITIES:  The  Fund  may also  purchase  securities  that are not
registered  under the  Securities  Act of 1933,  as  amended  (the  "1933  Act")
("restricted  securities"),  including  those  that can be  offered  and sold to
"qualified  institutional buyers" under Rule 144A under the 1933 Act ("Rule 144A
securities").  The Trust's Board of Trustees determines, based upon a continuing
review of the trading  markets for the  specific  144A  security,  whether  such
security is illiquid and thus subject to a Fund's  limitation  on investing  not
more than 15% of its net assets in illiquid investments,  or liquid and thus not
subject to such  limitation.  The Board of Trustees has adopted  guidelines  and
delegated  to the  Adviser  the daily  function of  determining  and  monitoring
liquidity of Rule 144A securities.  The Board,  however,  will retain sufficient
oversight and is ultimately  responsible for the determinations.  The Board will
carefully monitor a Fund's investments in Rule 144A securities, focusing on such
important  factors,  among others,  as valuation,  liquidity and availability of
information.  This  investment  practice could have the effect of increasing the
level of illiquidity in a Fund to the extent that qualified institutional buyers
become for a time  uninterested in purchasing these 144A 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, which
presents  certain risks.  As a result,  the Fund might not be able to sell these
securities  when the Adviser wishes to do so, or might have to sell them at less
than fair value.  In addition,  market  quotations  are less readily  available.
Therefore, judgment may at times play a greater role in valuing these securities
than in the case of unrestricted securities.

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

CORPORATE  ASSET-BACKED  SECURITIES:  The Fund may  invest in  corporate  asset-
backed  securities.  These  securities,  issued by trusts  and  special  purpose
corporations,  are backed by a pool of assets, such as credit card or automobile
loan receivables, representing the obligations of a number of different parties.
Corporate  asset-backed  securities present certain risks. For instance,  in the
case of credit card  receivables,  these  securities may not have the benefit of
any security interest in the related collateral. See the Statement of Additional
Information for further information on these securities.

LOAN PARTICIPATIONS AND OTHER DIRECT INDEBTEDNESS: The Fund may invest a portion
of its  assets  in "loan  participations"  and  other  direct  indebtedness.  By
purchasing a loan  participation,  the Fund acquires some or all of the interest
of a bank or other lending institution in a loan to a corporate  borrower.  Many
such loans are secured, and most impose restrictive  covenants which must be met
by the  borrower.  These loans are made  generally to finance  internal  growth,
mergers, acquisitions, stock repurchases, leveraged buy-outs and other corporate
activities.  Such loans may be in default at the time of purchase.  The Fund may
also purchase  other direct  indebtedness  such as trade or other claims against
companies,  which generally represent money owed by the company to a supplier of
goods  and  services.  These  claims  may also be  purchased  at a time when the
company is in  default.  Certain  of the loan  participations  and other  direct
indebtedness  acquired by the Fund may involve  revolving  credit  facilities or
other standby  financing  commitments  which obligate the Fund to pay additional
cash on a certain date or on demand.

The highly leveraged nature of many such loans and other direct indebtedness may
make such loans  especially  vulnerable to adverse changes in economic or market
conditions.  Loan participations and other direct indebtedness may not be in the
form of  securities  or may be subject to  restrictions  on  transfer,  and only
limited  opportunities  may exist to resell such instruments.  As a result,  the
Fund may be unable to sell such  investments at an opportune time or may have to
resell them at less than fair market  value.  For a further  discussion  of loan
participations,  other direct indebtedness and the risks related to transactions
therein, see the Statement of Additional Information.

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

OPTIONS

OPTIONS ON SECURITIES -- The Fund may write (sell)  covered call and put options
and purchase call and put options on securities.  The Fund will write options on
securities for the purpose of increasing its return on such securities and/or to
protect  the 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 the portfolio  security  underlying
the option,  or the increased  cost of portfolio  securities to be acquired.  In
contrast,  however,  if the price of the underlying  security moves adversely to
the Fund's  position,  the option may be exercised and the Fund will be required
to purchase or sell the underlying  security at a disadvantageous  price,  which
may only be  partially  offset by the amount of the  premium.  The Fund may also
write  combinations  of put and  call  options  on the same  security,  known as
"straddles." Such transactions can generate  additional  premium income but also
present increased risk.

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

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

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

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

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

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

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

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

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

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

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

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

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

PORTFOLIO TRADING
The Fund  intends to manage its  portfolio by buying and selling  securities  to
help attain its investment objective.  This may result in increases or decreases
in  the  Fund's  current  income   available  for  distribution  to  the  Fund's
shareholders  and in the  holding by the Fund of debt  securities  which sell at
moderate to  substantial  premiums or discounts  from face value.  The Fund will
engage  in  portfolio  trading  if it  believes  a  transaction,  net  of  costs
(including  custodian charges),  will help in attaining its investment objective
(see  "Portfolio  Transactions  and Brokerage  Commissions"  in the Statement of
Additional Information).

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

The policies  described  above are not  fundamental  and may be changed  without
shareholder approval,  as may the Fund's investment  objective.  A change in the
Fund's  investment  objective  may  result  in the  Fund  having  an  investment
objective  different  from  the  objective  which  the  shareholder   considered
appropriate at the time of investment in the Fund.

The  Statement  of  Additional   Information  includes  a  discussion  of  other
investment  policies  and a listing of specific  investment  restrictions  which
govern the Fund's  investment  policies.  The specific  investment  restrictions
listed in the Statement of  Additional  Information  may not be changed  without
shareholder  approval  (see  "Investment   Restrictions"  in  the  Statement  of
Additional Information). The Fund's investment limitations,  policies and rating
standards  are adhered to at the time of purchase or  utilization  of assets;  a
subsequent  change  in  circumstances  will not be  considered  to  result  in a
violation of policy.

6.  MANAGEMENT OF THE FUND
INVESTMENT  ADVISER -- MFS manages the Fund pursuant to an  Investment  Advisory
Agreement  dated  September  1, 1993 (the  "Advisory  Agreement").  The  Adviser
provides the Fund with overall investment advisory and administrative  services,
as well as general office facilities. Kevin R. Parke, a Senior Vice President of
the Adviser,  has been the Fund's  portfolio  manager since 1988.  Mr. Parke has
been  employed  by the  Adviser  since  1985.  Subject to such  policies  as the
Trustees may determine, the Adviser makes investment decisions for the Fund. For
its services and facilities, the Adviser receives a management fee, computed and
paid monthly, in an amount equal to 0.75% of the Fund's average daily net assets
for its then-current fiscal year.

For the  Fund's  fiscal  year  ended  November  30,  1993,  the  Fund's  current
investment adviser, MFS, together with the Fund's former investment adviser, LAI
(a wholly owned  subsidiary  of MFS) received  management  fees under the Fund's
Advisory Agreements of $3,481,771.

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

MFS is  America's  oldest  mutual  fund  organization.  MFS and its  predecessor
organizations  have a  history  of money  management  dating  from  1924 and the
founding of the first mutual fund in the United States,  Massachusetts Investors
Trust.   Net  assets  under  the  management  of  the  MFS   organization   were
approximately  $34.9  billion on behalf of  approximately  1.4 million  investor
accounts as of February 28, 1994. As of such date, the MFS organization  managed
approximately   $9.9  billion  of  assets  invested  in  equity  securities  and
approximately  $21.5  billion of assets  invested  in fixed  income  securities.
Approximately  $4.3  billion  of the  assets  managed  by MFS  are  invested  in
securities of foreign issuers and non-U.S. dollar denominated securities of U.S.
issuers.  MFS is a subsidiary of Sun Life of Canada  (U.S.),  which in turn is a
subsidiary of Sun Life Assurance  Company of Canada ("Sun Life").  The Directors
of MFS are A. Keith Brodkin,  Jeffrey L. Shames, Arnold D. Scott, John D. McNeil
and John R. Gardner.  Mr.  Brodkin is the Chairman,  Mr. Shames is the President
and Mr. Scott is the Secretary  and a Senior  Executive  Vice  President of MFS.
Messrs. McNeil and Gardner are the Chairman and President,  respectively, of Sun
Life.  Sun  Life,  a  mutual  life  insurance  company,  is one  of the  largest
international  life  insurance  companies  and has been  operating in the United
States  since  1895,  establishing  a  headquarters  office  here in  1973.  The
executive officers of MFS report to the Chairman of Sun Life.

A. Keith  Brodkin,  the Chairman of MFS, is the  Chairman  and  President of the
Trust. W. Thomas London,  Stephen E. Cavan,  James R.  Bordewick,  Jr., Linda J.
Hoard, Leslie J. Nanberg and James O. Yost, all of whom are officers of MFS, are
officers of the Trust.

DISTRIBUTOR  -- FSI, a wholly owned  subsidiary  of MFS, is the  distributor  of
shares  of the Fund and also  serves  as  distributor  for each of the other MFS
Funds.

SHAREHOLDER  SERVICING  AGENT -- MFS  Service  Center,  Inc.  (the  "Shareholder
Servicing  Agent"),  a wholly owned subsidiary of MFS, performs transfer agency,
certain dividend disbursing agency and other services for the Fund.


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

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

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

  $1,000,000 or more .....................     None<F2>        None<F2>         See Below<F2>

<FN>
<F1> Because of rounding in the  calculation  of offering  price,  actual  sales
     charges  may be more or less than those  calculated  using the  percentages
     above.
<F2> A CDSC may apply in certain  circumstances.  FSI will pay a  commission  on
     purchases of $1 million or more.
</FN>
</TABLE>

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

In determining whether a CDSC on such Class A shares is payable, and, if so, the
amount of the charge,  it is assumed that shares not subject to the CDSC are the
first redeemed followed by other shares held for the longest period of time. All
investments  made during a calendar  month,  regardless of when during the month
the  investment  occurred,  will age one  month on the last day of the month and
each subsequent month. Except as noted below, the CDSC on Class A shares will be
waived in the case of: (i)  exchanges  (except  that if the shares  acquired  by
exchange were then redeemed within 12 months of the initial purchase (other than
in connection  with subsequent  exchanges to other MFS Funds),  the charge would
not be waived);  (ii)  distributions  to  participants  from a  retirement  plan
qualified under sections 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 that if the  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  MFS Funds and other  funds
owned or being purchased,  the existence of an agreement to purchase  additional
shares during a 13-month  period (or 36-month period for purchases of $1 million
or more) or other  special  purchase  programs.  A  description  of the Right of
Accumulation, Letter of Intent and Group Purchases privileges by which the sales
charge may be reduced is set forth in the Statement of  Additional  Information.
In  addition,  FSI,  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 net asset value  through the automatic
reinvestment  of Class A and Class B  periodic  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 on a pro
rata portion  thereof) as described above if the shareholder  redeems his or her
shares  within a year of  purchase.  (Shareholders  who  purchase  shares at NAV
pursuant  to these  conditions  are called "$3 million  shareholders").  Class A
shares of the Fund may be sold at their net asset  value to the  officers of the
Trust,  to any of the subsidiary  companies of Sun Life, to eligible  Directors,
officers, employees (including retired employees) and agents of MFS, Sun Life or
any of their subsidiary companies, to any trust, pension,  profit-sharing or any
other benefit plan for such persons, to any trustees and retired trustees of any
investment company for which FSI serves as distributor or principal underwriter,
and to certain family members of such  individuals  and their spouses,  provided
the shares will not be resold except to the Fund. Class A shares of the Fund may
be sold at net asset value to any employee,  partner,  officer or trustee of any
sub-adviser to any MFS Fund and to certain  family  members of such  individuals
and their spouses, or to any trust, pensions, 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 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, pensions, 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 affiliate, 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. 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.  In addition,  Class A shares may be sold at their net
asset value in connection  with the  acquisition or liquidation of the assets of
other investment  companies or personal  holding  companies.  Insurance  company
separate  accounts  may  purchase  Class A shares of the Fund at their net asset
value. Class A shares of the Fund may also be purchased at their net asset value
by retirement plans where third party  administrators of such plans have entered
into certain arrangements with FSI or its affiliates provided that no commission
is paid to  dealers.  Class A shares of the Fund may 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.
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 purchased during the period January 1, 1993 up to September 1,
 1993 will be 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:

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 and former  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 shares bear to the  shareholder's  total Class B
shares not acquired through such reinvestment.  The conversion of Class B shares
to Class A shares is subject to the continuing availability of a ruling from the
Internal  Revenue Service or an opinion of counsel that such conversion will not
constitute a taxable event for Federal tax  purposes.  There can be no assurance
that such ruling or opinion will be  available,  and the  conversion  of Class B
shares  to  Class A shares  will not  occur if such  ruling  or  opinion  is not
available.  In such event, Class B shares would continue to be subject to higher
expenses than Class A shares for an indefinite period.

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

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

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

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

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

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

EXCHANGES
Subject to the  requirements  set forth  below,  some or all of the shares in an
account with the Fund for which payment has been received by the Fund (i.e.,  an
established account) may be exchanged for shares of the same class of any of the
other MFS Funds (if available for sale) at net asset value.  Shares of one class
may not be exchanged for shares of any other class.  Exchanges will be made only
after  instructions  in writing or by  telephone  (an  "Exchange  Request")  are
received for an established account by the Shareholder Servicing Agent in proper
form (i.e., if in writing -- signed by the record owner(s) exactly as the shares
are registered; if by telephone -- proper account identification is given by the
dealer or shareholder  of record);  and each exchange must involve either shares
having an aggregate value of at least $1,000 ($50 in the case of retirement plan
participants  whose  sponsoring  organizations  subscribe to the MFS FUNDamental
401(k) Plan or another similar 401(k) recordkeeping system made available by MFS
Service Center,  Inc.) or all the shares in the account. If the Exchange Request
is received by the Shareholder  Servicing Agent on any business day prior to the
close of regular  trading on the New York Stock Exchange (the  "Exchange"),  the
exchange  usually will occur on that day if all the requirements set forth above
have been complied with at that time. No more than five exchanges may be made in
any one Exchange Request by telephone.  Additional  information  concerning this
exchange  privilege  and  prospectuses  for any of the  other  MFS  Funds may be
obtained  from  investment  dealers  or  the  Shareholder   Servicing  Agent.  A
shareholder  should read the  prospectus  of the other MFS Fund and consider the
differences in objectives and policies  before making any exchange.  For federal
and (generally)  state income tax purposes,  an exchange is treated as a sale of
the shares exchanged and, therefore,  an exchange could result in a gain or loss
to the shareholder making the exchange. Exchanges by telephone are automatically
available  to most  non-retirement  plan  accounts and certain  retirement  plan
accounts.   For  further  information   regarding  exchanges  by  telephone  see
"Redemptions By Telephone." The exchange  privilege (or any aspect of it) may be
changed or discontinued and is subject to certain limitations, including certain
restrictions on purchases by market timer accounts (see "Purchases").

REDEMPTIONS AND REPURCHASES
A  shareholder  may  withdraw all or any portion of the amount in his account on
any date on which the Fund is open for business by redeeming shares at their net
asset  value  or by  selling  such  shares  to the  Fund  through  a  dealer  (a
repurchase).  Since the net asset  value of  shares  of the  account  fluctuate,
redemptions or repurchases, which are taxable transactions, are likely to 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 the stock power,  written  request for redemption,
letter of  instruction or  certificate  must be endorsed by the record  owner(s)
exactly as the shares are registered and the signature(s)  must be guaranteed in
the manner set forth below under the caption "Signature Guarantee." In addition,
in some cases "good order" may require the  furnishing of additional  documents.
The Shareholder  Servicing  Agent may make certain de minimis  exceptions to the
above  requirements  for  redemption.  Within  seven  days  after  receipt  of a
redemption request by the Shareholder  Servicing Agent in "good order," the Fund
will make  payment in cash of the net asset value of the shares next  determined
after  such  redemption  request  was  received,  reduced  by the  amount of any
applicable  CDSC 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  Investment
Company Act of 1940 (the "1940 Act"), if an emergency exists (see "Tax Status").

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

C. REPURCHASE THROUGH A DEALER -- If a shareholder desires to sell his shares at
net asset value through his securities  dealer (a  repurchase),  the shareholder
can place a repurchase  order with his dealer,  who may charge the shareholder a
fee.  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  portfolio
securities  (instead of cash). The securities so distributed  would be valued at
the same amount as that assigned to them in calculating  the net asset value for
the shares being sold. If a shareholder  received a  distribution  in kind,  the
shareholder  could incur  brokerage or  transaction  charges in  converting  the
securities to cash.

Due to the relatively high cost of maintaining small accounts, the Fund reserves
the right to redeem  shares in any account for their  then-current  value (which
will be promptly paid to the shareholder) if at any time the total investment in
such  account  drops below $500  because of  redemptions,  except in the case of
accounts  established  for monthly  automatic  investments  and certain  payroll
savings programs,  Automatic 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  ("Direct  Purchases")  will be
subject  to a CDSC for a period of 12  months  (in the case of  purchases  of $1
million  or more of Class A shares)  or six years (in the case of  purchases  of
Class B shares).  Purchases  of Class A shares  made  during a  calendar  month,
regardless of when during the month the investment occurred,  will age one month
on the last day of the month and each subsequent month. Class B shares purchased
on or after January 1, 1993 will be aggregated on a calendar  month basis -- all
transactions  made during a calendar month,  regardless of when during the month
they have  occurred,  will age one year at the close of business on the last day
of such month in the following calendar year and each subsequent year. For Class
B shares of the Fund purchased  prior to January 1, 1993,  transactions  will be
aggregated on a calendar year basis -- all  transactions  made during a calendar
year,  regardless of when during the year they have occurred,  will age one year
at the close of business on December 31 of that year and each  subsequent  year.
At the time of a  redemption,  the amount by which the value of a  shareholder's
account for a particular class  represented by Direct Purchases  exceeds the sum
of the six calendar year  aggregations (12 months in the case of purchases of $1
million or more of Class A shares) of Direct  Purchases may be redeemed  without
charge ("Free Amount").  Moreover, no CDSC is ever assessed on additional shares
acquired  through  the  automatic  reinvestment  of  dividends  or capital  gain
distributions ("Reinvested Shares").

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

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

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. 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  reduced,  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.  Payments under the Class A
Distribution Plan will commence on the date on which the value of the Fund's net
assets  attributable to Class A shares first equals or exceeds  $40,000,000,  at
which  time FSI  intends  to waive  the  0.10%  distribution  fee to which it is
entitled  under the plan until such time as the  payment of this fee is approved
by the Trust's  Board of Trustees.  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 to 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  Distribution  Plan provides that the
Fund will pay FSI a daily  distribution fee equal on an annual basis to 0.75% of
the Fund's average daily net assets  attributable to Class B shares and will pay
FSI a  service  fee of up to 0.25%  per annum of the  Fund's  average  daily net
assets  attributable to Class B shares (which FSI will in turn pay to securities
dealers which enter into a sales agreement with FSI at a rate of up to 0.25% per
annum of the  Fund's  average  daily net assets  attributable  to Class B shares
owned by investors  for whom that  securities  dealer is the holder or dealer of
record).  This service fee is intended to be  additional  consideration  for all
personal  services and/or account  maintenance  services  rendered by the dealer
with respect to Class B shares. Fees payable under the Class B Distribution Plan
are charged to, and therefore  reduce,  income allocated to Class B shares.  The
Class B  Distribution  Plan  also  provides  that FSI  will  receive  all  CDSCs
attributable  to Class B shares (see  "Redemptions  and  Repurchases  of Shares"
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 to 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  substantially  all of its net investment income for any
calendar year to its  shareholders as dividends on an annual basis. The Fund may
make one or more distributions during the calendar year to its shareholders from
any long-term capital gains and the Fund may also 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 paid. See "Tax Status" and "Shareholder Services -- Distribution
Options"  below.  Distributions  paid by the Fund with respect to Class A shares
will generally be greater than those paid with respect to Class B shares because
expenses attributable to Class B shares will generally be higher.

TAX STATUS
The Fund is treated as an entity separate from the other series of the Trust for
federal  income  tax  purposes.  In order to  minimize  the taxes the Fund would
otherwise  be required to pay,  the Fund has elected and 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  set out in the  Code.  It is not  expected  that the Fund  will be
required  to pay any  entity  level  federal  income or excise  taxes,  although
foreign  source income earned by the Fund may be subject to foreign  withholding
taxes.  Shareholders of the Fund normally will have to pay federal income taxes,
and any state 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
gain  distributions)  may  qualify  for  the  dividends-received  deduction  for
corporations.

Shortly  after the end of each  calendar  year,  each  shareholder  will receive
information for tax purposes on the Fund's dividends and  distributions for each
calendar year,  including the portion  taxable as ordinary  income,  the portion
taxable as long-term capital gains, the portion,  if any,  representing a return
of capital  (which is  generally  free of current  taxes but  results in a basis
reduction), and the amount, if any, of federal income tax withheld.

The Fund  intends  to  withhold  U.S.  federal  income tax at the rate of 30% on
dividends and certain other  payments that are subject to such  withholding  and
are  made to  persons  who are  neither  citizens  nor  residents  of the  U.S.,
regardless of whether a lower rate may be permitted under an applicable  treaty.
The Fund is also required in certain  circumstances to apply backup  withholding
of 31% of taxable  dividends and  redemption  proceeds  paid to any  shareholder
(including  a  shareholder  who is neither a citizen nor a resident of the U.S.)
who does not furnish to the Fund certain  information and  certifications or who
is  otherwise  subject  to  backup  withholding.  Backup  withholding  will not,
however,  be applied to  payments  which have been  subject to 30%  withholding.
Prospective  investors should read the Fund's Account Application for additional
information  regarding  backup  withholding  of  federal  income  tax and should
consult their own tax advisor as to the tax consequences of an investment in the
Fund.

NET ASSET VALUE
The net asset value per share of each class of the Fund is  determined  each day
during which the Exchange is open for trading.  This  determination is made once
each day as of the close of regular  trading on the  Exchange by  deducting  the
amount of the liabilities attributable to the class from the value of the assets
attributable  to that class and dividing the  difference by the number of shares
of the class outstanding. Assets in the Fund's portfolio are valued on the basis
of their current  values or otherwise at their fair values,  as described in the
Statement of Additional Information. All investments and assets are expressed in
U.S. dollars based upon current currency exchange rates. The net asset value 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, one of four series of the Trust,  has two classes of shares,  entitled
Class A and Class B Shares of Beneficial Interest (without par value). The Trust
has  reserved  the right to create and issue  additional  classes  and series of
shares, in which case each class of shares of a series would participate equally
in the  earnings,  dividends  and  assets  attributable  to that  class  of that
particular series. Shareholders are entitled to one vote for each share held and
shares of each series would be entitled to vote separately to approve investment
advisory  agreements  or changes in investment  restrictions,  but shares of all
series  would vote  together  in the  election  of  Trustees  and  selection  of
accountants. Additionally, each class of shares of a series will vote separately
on any  material  increases  in the fees under its  Distribution  Plan or on any
other matter that affects  solely that class of shares,  but will otherwise vote
together  with all other  classes of shares of the series on all other  matters.
The Trust does not intend to hold annual shareholder  meetings.  The Declaration
of Trust provides that a Trustee may be removed from office in certain instances
(see "Description of Shares,  Voting Rights and Liabilities" in the Statement of
Additional Information).

Each share of a class of the Fund represents an equal proportionate  interest in
the Fund  with  each  other  class  share,  subject  to the  liabilities  of the
particular class. Shares have no pre-emptive or conversion rights (except as set
forth 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 Trust is an entity of the type commonly known as a  "Massachusetts  business
trust." Under Massachusetts law, shareholders of such a trust may, under certain
circumstances,  be held  personally  liable  as  partners  for its  obligations.
However,  the risk of a  shareholder  incurring  financial  loss on  account  of
shareholder  liability  is limited  to  circumstances  in which both  inadequate
insurance  existed (e.g.,  fidelity bonding and errors and omissions  insurance)
and the Trust itself was unable to meet its obligations.

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

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

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

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

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

    -- 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.  Checks for  dividends  and capital
gain  distributions in amounts less than $10 will automatically be reinvested in
additional shares of the Fund. Any request to change a distribution  option must
be received by the Shareholder Servicing Agent by the record date for a dividend
or distribution in order to be effective for that dividend or  distribution.  No
interest  will  accrue  on  amounts  represented  by  uncashed  distribution  or
redemption checks.

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

     LETTER  OF  INTENT:  If a  shareholder  (other  than a group  purchaser  as
described in the Statement of  Additional  Information)  anticipates  purchasing
$100,000  or more of Class A shares  of the Fund  alone or in  combination  with
shares of any class 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 another MFS Fund.  Furthermore,  distributions  made by the Fund may be
automatically invested at net asset value in shares of the same class of another
MFS  Fund,  if  shares of such Fund are  available  for sale  (and  without  any
applicable CDSC).

     SYSTEMATIC WITHDRAWAL PLAN: A shareholder (except a $3 Million Shareholder)
may direct the Shareholder Servicing Agent to send him (or anyone he designates)
regular periodic  payments,  as designated on the Account  Application and based
upon the value of his account.  Each payment under a Systematic  Withdrawal Plan
("SWP")  must be at least $100,  except in certain  limited  circumstances.  The
aggregate  withdrawals  of Class B shares in any year pursuant to a SWP will not
be  subject  to a CDSC  and are  generally  limited  to 10% of the  value of the
account at the time of the establishment of the SWP. The CDSC will not be waived
in the case of SWP redemptions of Class A shares which are subject to a CDSC.

DOLLAR COST AVERAGING PROGRAMS --

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

     AUTOMATIC EXCHANGE PLAN:  Shareholders  having account balances of at least
$5,000 in any MFS Fund may exchange their shares for the same class of shares of
the other MFS Funds under the Automatic  Exchange  Plan, a dollar cost averaging
program. 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.

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

The Fund's Statement of Additional  Information,  dated April 1, 1994,  contains
more detailed  information about the Trust and the Fund,  including  information

sale of  options,  Futures  Contracts,  Options  on Futures  Contracts,  Forward
Contracts and Options on Foreign  Currencies,  (ii) the  Trustees,  officers and
investment adviser,  (iii) portfolio trading, (iv) the Fund's shares,  including

total rate of return  quotations  and (viii)  various  services  and  privileges
provided by the Fund for the benefit of its shareholders,  including  additional
information with respect to the exchange privilege.


                                                                    APPENDIX A

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

                        MOODY'S INVESTORS SERVICE, INC.

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

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

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

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

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

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

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

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

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

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

Should no rating be assigned, the reason may be one of the following:

     1. an application for rating was not received or accepted;

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

     3. there is a lack of essential data pertaining to the issue or issuer; and

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

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

                       STANDARD & POOR'S RATINGS GROUP

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

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

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

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

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

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

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

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

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

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

     D: Debt rated D is in payment  default.  The D rating category is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired,  unless S&P believes that such payments
will be made during such grace  period.  The D rating also will be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

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

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


                                                                    APPENDIX B

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

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

FEDERAL FARM CREDIT CONSOLIDATED  SYSTEMWIDE NOTES AND BONDS -- are bonds issued
by a cooperatively owned nationwide system of banks and associations  supervised

mortgage  loan included in the pool is also insured or guaranteed by the Federal
Housing  Administration,   the  Veterans  Administration  or  the  Farmers  Home
Administration.

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

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

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

A-1 AND P-1 COMMERCIAL PAPER RATINGS
Description of S&P and Moody's highest commercial paper ratings:

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

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