securities)  consistent with prudent employment of capital. The Fund's secondary
objective  is to take  advantage  of  opportunities  for growth of  capital  and
income. The Fund is a diversified series of MFS Series Trust V (the "Trust"), an

invested in equity  securities (see "Investment  Objectives and Policies").  The
minimum initial investment generally is $1,000 per account (see "Purchases").

The Fund's  investment  adviser  and  distributor  are  Massachusetts  Financial
Services Company ("MFS") and MFS Fund Distributors,  Inc. ("MFD"), respectively,
both of which are located at 500 Boylston Street, Boston, Massachusetts 02116.

SHARES OF THE FUND ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR ENDORSED
BY, ANY BANK AND THE SHARES ARE NOT  FEDERALLY  INSURED BY THE  FEDERAL  DEPOSIT
INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER AGENCY.

This Prospectus  sets forth  concisely the information  concerning the Trust and
the Fund that a prospective investor ought to know before investing.  The Trust,
on behalf of the Fund,  has filed with the  Securities  and Exchange  Commission
(the "SEC") a Statement of Additional Information, dated February 1, 1995, which
contains  more  detailed  information  about  the  Trust  and  the  Fund  and is
incorporated  into  this  Prospectus  by  reference.  See page 27 for a  further
description  of the  information  set  forth  in  the  Statement  of  Additional

<FN>
- ---------
<F1> 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").
<F2> The  Fund has  adopted  a  Distribution  Plan  for its  Class A  shares  in
     accordance  with Rule 12b-1 under the  Investment  Company Act of 1940,  as
     amended (the "1940 Act"),  which  provides  that it will pay  distribution/
     service fees aggregating up to (but not necessarily all of) 0.35% per annum
     of the  average  daily net assets  attributable  to the Class A shares (see
     "Distribution Plans").  Currently,  the service fee is reduced to 0.15% per
     annum for  shares  sold  prior to  October  1, 1989 and the 0.10% per annum
     distribution  fee is being  waived.  After a  substantial  period  of time,
     distribution expenses paid under this Plan, together with the initial sales
     charge,  may total more than the maximum  sales charge that would have been
     permissible if imposed entirely as an initial sales charge.
<F3> The Fund has adopted  separate  Distribution  Plans for its Class B and its
     Class C shares in  accordance  with Rule  12b-1  under the 1940 Act,  which
     provide that it will pay  distribution/service  fees aggregating up to (but
     not  necessarily  all of) 1.00% per annum of the  average  daily net assets
     attributable to the Class B shares under the Class B Distribution  Plan and
     the Class C shares under the Class C Distribution  Plan (see  "Distribution
     Plans").  After a substantial  period of time,  distribution  expenses paid
     under these Plans,  together with any CDSC payable upon redemption of Class
     B shares, may total more than the maximum sales charge that would have been
     permissibie if imposed entirely as an initial sales charge.
<F4> Except for the shareholder servicing agent fee component,  "Other Expenses"
     is based  on  Class A  expenses  incurred  during  the  fiscal  year  ended
     September 30, 1994. The shareholder servicing agent fee component of "Other
     Expenses" is a  predetermined  percentage  based upon the Fund's net assets
     attributable to each class.

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 of the Prospectus:  (i) varying sales charges on
share  purchases  --  "Purchases";  (ii)  varying  CDSCs --  "Purchases";  (iii)
management fees -- "Investment Adviser"; and (iv) Rule 12b-1 (i.e., distribution
plan) fees -- "Distribution Plans."

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

2. THE FUND
MFS Total  Return Fund (the "Fund") is a  diversified  series of MFS
Series Trust V (the "Trust"),  an open-end  management  investment company which
was  organized  as a  business  trust  under  the  laws of The  Commonwealth  of
Massachusetts  in 1984. The Fund and its predecessor have been in business since
1970. The Trust  presently  consists of two series,  each of which  represents a
portfolio with separate investment policies. Shares of the Fund are continuously
sold to the  public  and the Fund  buys  securities  (stocks,  bonds  and  other
instruments)  for its  portfolio.  Three classes of shares of the Fund currently
are offered to the general public. Class A shares are offered at net asset value
plus an initial sales charge (or a contingent  deferred  sales charge (a "CDSC")
in the case of  certain  purchases  of $1  million  or more)  and  subject  to a
Distribution Plan,  providing for an annual  distribution fee and a service fee.
Class B shares are offered at net asset value  without an initial  sales  charge
but  subject  to a  CDSC  and  a  Distribution  Plan  providing  for  an  annual
distribution fee and 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.  Class C shares are  offered  at net asset  value
without an initial  sales  charge or a CDSC but subject to a  Distribution  Plan
providing for an annual  distribution fee and service fee which are equal to the
Class B  distribution  fee and service fee. Class C shares do not convert to any
other class of shares of the Fund.

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. 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 objectives and policies. The
selection of  investments  and the way they are managed depend on conditions and
trends in the economy and the financial  marketplaces.  The Trust also offers to
buy back (redeem)  shares of the Fund from Fund  shareholders at any time at net
asset value, less any applicable CDSC.

3. CONDENSED  FINANCIAL  INFORMATION -- PER SHARE INCOME AND CAPITAL CHANGES
The  following  information  should be read in  conjunction  with the  financial

4.  INVESTMENT OBJECTIVES AND POLICIES
INVESTMENT  OBJECTIVES -- The Fund's primary  investment  objective is to obtain
above-average  income  (compared  to a  portfolio  entirely  invested  in equity
securities)  consistent  with the prudent  employment of capital.  While current
income is the primary  objective,  the Fund believes that there should also be a
reasonable  opportunity for growth of capital and income,  since many securities
offering a better than average yield may also possess growth potential. Thus, in
selecting  securities  for its  portfolio,  the  Fund  considers  each of  these
objectives.  Generally, at least 40% of the Fund's assets are invested in equity
securities.  Any investment involves risk and there can be no assurance that the
Fund will achieve its investment objectives.

INVESTMENT  POLICIES  -- The  Fund's  policy  is to  invest  in a broad  list of
securities,  including short-term  obligations.  The list may be diversified not
only by companies  and  industries,  but also by type of security.  Fixed income
securities and equity  securities  (which include:  common and preferred stocks;
securities such as bonds,  warrants or rights that are  convertible  into stock;
and  depositary  receipts for those  securities)  may be held by the Fund.  Some
fixed  income  securities  may also  have a call on  common  stock by means of a
conversion  privilege or attached warrants.  The Fund may vary the percentage of
assets  invested in any one type of security in  accordance  with the  Adviser's
interpretation  of economic  and money  market  conditions,  fiscal and monetary
policy and underlying  security values.  The Fund's debt investments may consist
of both "investment  grade" securities (rated Baa or better by Moody's Investors
Service,  Inc. ("Moody's") or BBB or better by Standard and Poor's Ratings Group
("S&P") or Fitch  Investors  Service,  Inc.  ("Fitch")) and securities  that are
unrated or are in the lower rating  categories  (rated Ba or lower by Moody's or
BB or lower by S&P or Fitch)  (commonly  known as "junk bonds")  including up to
20% of its assets in  nonconvertible  fixed income  securities that are in these
lower rating categories and comparable  unrated securities (see "Risk Factors --
Lower  Rated  Bonds"  below).  Generally,  most  of the  Fund's  long-term  debt
investments  will consist of "investment  grade"  securities.  See Appendix A to
this  Prospectus  for a description  of these ratings and Appendix B for a chart
showing the Fund's  holdings of  fixed-income  securities  broken down by rating
category  as of the end of its most  recent  fiscal  year.  It is not the Fund's
policy to rely  exclusively  on  ratings  issued by  established  credit  rating
agencies  but  rather  to  supplement   such  ratings  with  the  Adviser's  own
independent and ongoing review of credit quality.

U.S.  GOVERNMENT  SECURITIES:  The  Fund  may  also  invest  in U.S.  Government
securities, including: (1) U.S. Treasury obligations, which differ only in their
interest  rates,   maturities  and  times  of  issuance:   U.S.  Treasury  bills
(maturities of one year or less);  U.S. Treasury notes (maturities of one to ten
years);  and U.S.  Treasury  bonds  (generally  maturities  of greater  than ten
years),  all of which  are  backed  by the full  faith  and  credit  of the U.S.
Government; and (2) obligations issued or guaranteed by U.S. Government agencies
or  instrumentalities,  some of which are backed by the full faith and credit of
the U.S.  Treasury,  e.g.,  direct  pass-through  certificates of the Government
National Mortgage Association ("GNMA"); some of which are supported by the right
of the issuer to borrow from the U.S. Government,  e.g.,  obligations of Federal
Home Loan  Banks;  and some of which are backed only by the credit of the issuer
itself, e.g., obligations of the Student Loan Marketing Association.

MORTGAGE PASS-THROUGH  SECURITIES:  The Fund may invest in mortgage pass-through
securities.   Mortgage  pass-through   securities  are  securities  representing
interests  in "pools" of  mortgage  loans.  Monthly  payments  of  interest  and
principal by the  individual  borrowers on mortgages  are passed  through to the
holders of the  securities  (net of fees paid to the issuer or  guarantor of the
securities)  as the  mortgages in the  underlying  mortgage  pools are paid off.
Payment of principal and interest on some mortgage pass-through  securities (but
not the market value of the securities themselves) may be guaranteed by the full
faith and credit of the U.S. Government (in the case of securities guaranteed by
GNMA);  or guaranteed  by U.S.  Government-sponsored  corporations  (such as the
Federal  National  Mortgage  Association  or  the  Federal  Home  Loan  Mortgage
Corporation, which are supported only by the discretionary authority of the U.S.
Government  to  purchase  the  agency's   obligations).   Mortgage  pass-through
securities  may also be issued by  non-governmental  issuers (such as commercial
banks,  savings and loan  institutions,  private mortgage  insurance  companies,
mortgage  bankers and other  secondary  market  issuers).  See the  Statement of
Additional Information for a further discussion of these securities.

ZERO  COUPON  BONDS,  DEFERRED  INTEREST  BONDS  AND  PIK  BONDS:  Fixed  income
securities that the Fund may invest in also include zero coupon bonds,  deferred
interest bonds and bonds on which the interest is payable in kind ("PIK bonds").
Zero coupon and deferred interest bonds are debt obligations which are issued or
purchased at a significant  discount from face value. The discount  approximates
the total amount of interest the bonds will accrue and compound  over the period
until  maturity  or the  first  interest  payment  date  at a rate  of  interest
reflecting  the market rate of the security at the time of issuance.  While zero
coupon bonds do not require the periodic payment of interest,  deferred interest
bonds  provide  for a period of delay  before the  regular  payment of  interest
begins.  PIK bonds are debt  obligations  which provide that the issuer  thereof
may,  at its  option,  pay  interest  on such  bonds  in cash or in the  form of
additional debt obligations.  Such investments  benefit the issuer by mitigating
its need for cash to meet debt service, but also require a higher rate of return
to  attract  investors  who are  willing to defer  receipt  of such  cash.  Such
investments may experience  greater volatility in market value due to changes in
interest rates than debt  obligations  which make regular  payments of interest.
The Fund will accrue income on such investments for tax and accounting purposes,
as required,  which is distributable to shareholders and which,  because no cash
is  received  at the time of  accrual,  may  require  the  liquidation  of other
portfolio securities to satisfy the Fund's distribution obligations.

FOREIGN  SECURITIES:  The Fund may  invest up to 20% (and  generally  expects to
invest between 10% and 20%) of its total assets in foreign  securities which are
not traded on a U.S.  exchange (not  including  American  Depositary  Receipts).
Investing  in  securities  of  foreign  issuers  generally  involves  risks  not
ordinarily  associated with investing in securities of domestic  issuers.  These
include changes in currency rates,  exchange control  regulations,  governmental
administration  or economic or monetary  policy (in the United States or abroad)
or  circumstances  in  dealings  between  nations.  Costs  may  be  incurred  in
connection with conversions between various currencies.  Special  considerations
may  also  include  more  limited  information  about  foreign  issuers,  higher
brokerage  costs,  different  accounting  standards and thinner trading markets.
Foreign  securities  markets may also be less  liquid,  more  volatile  and less
subject to government  supervision  than in the United  States.  Investments  in
foreign  countries could be affected by other factors  including  expropriation,
confiscatory  taxation  and  potential  difficulties  in  enforcing  contractual
obligations and could be subject to extended  settlement  periods.  The Fund may
hold  foreign  currency  received  in  connection  with  investments  in foreign
securities  when,  in the judgment of the  Adviser,  it would be  beneficial  to
convert such currency into U.S.  dollars at a later date,  based on  anticipated
changes in the relevant  exchange rate. The Fund may also hold foreign  currency
in  anticipation  of  purchasing  foreign  securities.   See  the  Statement  of
Additional  Information  for further  discussion of foreign  securities  and the
holding of foreign currency, as well as the associated risks.

EMERGING  MARKET  SECURITIES:  The Fund may invest in  countries or regions with
relatively low gross national  product per capita  compared to the world's major
economies,  and in countries or regions with the  potential  for rapid  economic
growth (emerging markets). Emerging markets will include any country: (i) having
an "emerging stock market" as defined by the International  Finance Corporation;
(ii) with low- to middle-income  economies  according to the International  Bank
for  Reconstruction  and Development  (the "World Bank");  (iii) listed in World
Bank  publications  as  developing;  or (iv)  determined by the Adviser to be an
emerging  market as defined  above.  The Fund may invest in  securities  of: (i)
companies  the  principal  securities  trading  market for which is an  emerging
market country; (ii) companies organized under the laws of, and with a principal
office  in,  an  emerging  market  country;   (iii)  companies  whose  principal
activities are located in emerging market  countries;  (iv) companies  traded in
any market that derive 50% or more of their total  revenue  from either goods or
services produced in an emerging market or sold in an emerging market.

AMERICAN  DEPOSITARY  RECEIPTS:  The  Fund may  invest  in  American  Depositary
Receipts ("ADRs") which are certificates  issued by a U.S. depository (usually a
bank) and  represent a specified  quantity of shares of an  underlying  non-U.S.
stock on deposit  with a custodian  bank as  collateral.  Because  ADRs trade on
United States securities  exchanges,  the Adviser does not treat them as foreign
securities. However, they are subject to many of the risks of foreign securities
such as changes in exchange  rates and more limited  information  about  foreign
issuers.

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

LENDING  OF  SECURITIES:  The Fund may seek to  increase  its  income by lending
portfolio securities.  Such loans will usually be made only to member firms (and
subsidiaries  thereof) of the New York Stock Exchange and to member banks of the
Federal  Reserve  System,  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 will continue to collect the equivalent of interest
on the  securities  loaned  and  will  also  receive  either  interest  (through
investment of cash  collateral) or a fee (if the  collateral is U.S.  Government
securities).

"WHEN-ISSUED" SECURITIES: The Fund may purchase securities on a "when-issued" or
on a "forward delivery" basis, which means that the securities will be delivered
to the Fund at a future date  usually  beyond  customary  settlement  time.  The
commitment  to purchase a security  for which  payment  will be made on a future
date may be deemed a separate security. The Fund does not pay for the securities
until received,  and does not start earning interest on the securities until the
contractual  settlement date. In order to invest its assets  immediately,  while
awaiting delivery of securities  purchased on such bases, the Fund will normally
invest in cash,  short-term  money  market  instruments  and high  quality  debt
securities.

INDEXED  SECURITIES:  The Fund may invest in indexed  securities  whose value is
linked to foreign  currencies,  interest rates,  commodities,  indices, or other
financial  indicators.  Most indexed  securities are short to intermediate  term
fixed-income  securities whose values at maturity or interest rates rise or fall
according to the change in one or more specified underlying instruments. Indexed
securities  may  include  securities  that have  embedded  swaps (see "Swaps and
Related  Transactions").  Indexed  securities  may be  positively  or negatively
indexed (i.e., their value may increase or decrease if the underlying instrument
appreciates),  and may have return characteristics similar to direct investments
in the  underlying  instrument  or to  one or  more  options  on the  underlying
instrument.  Indexed  securities  may  be  more  volatile  than  the  underlying
instrument itself.

MORTGAGE  "DOLLAR ROLL"  TRANSACTIONS:  The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers  pursuant to which the
Fund sells  mortgage-backed  securities  for  delivery in the future  (generally
within 30 days) and simultaneously contracts to repurchase substantially similar
(same type, coupon and maturity) securities on a specified future date. The Fund
will only enter into  covered  rolls.  A  "covered  roll" is a specific  type of
dollar roll for which there is an offsetting  cash position or a cash equivalent
security position which matures on or before the forward  settlement date of the
dollar roll transaction.

LOAN PARTICIPATIONS AND OTHER DIRECT INDEBTEDNESS: The Fund may invest a portion
of its assets in "loan participations." 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  trade or other  claims
against  companies,  which  generally  represent  money owed by the company to a
supplier of goods or services. These claims may also be purchased at a time when
the company is in default.  Certain of the loan  participations  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 may make such loans  especially
vulnerable  to  adverse   changes  in  economic  or  market   conditions.   Loan
participations and other direct investments 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 and the
risks  related  to  transactions   therein,  see  the  Statement  of  Additional
Information.

SWAPS AND RELATED TRANSACTIONS: As one way of managing its exposure to different
types of  investments,  the Fund may enter into  interest  rate swaps,  currency
swaps and other types of available swap  agreements,  such as caps,  collars and
floors.  Swaps  involve  the  exchange  by the Fund with  another  party of cash
payments based upon different interest rate indices, currencies, or other prices
or rates, such as the value of mortgage  prepayment  rates. For example,  in the
typical  interest rate swap, the Fund might exchange a sequence of cash payments
based on a floating rate index for cash payments based on a fixed rate. Payments
made by both  parties  to a swap  transaction  are based on a  principal  amount
determined by the parties.

The Fund may also purchase and sell caps,  floors and collars.  In a typical cap
or floor  agreement,  one party  agrees to make  payments  only under  specified
circumstances,  usually in return for payment of a fee by the counterparty.  For
example,  the purchase of an interest rate cap entitles the buyer, to the extent
that a  specified  index  exceeds a  predetermined  interest  rate,  to  receive
payments  of  interest  on  a  contractually-based  principal  amount  from  the
counterparty  selling such interest rate cap. The sale of an interest rate floor
obligates  the seller to make  payments to the extent that a specified  interest
rate falls below an agreed-upon level. A collar arrangement combines elements of
buying a cap and selling a floor.

Swap agreements  will tend to shift a Fund investment  exposure from one type of
investment  to another.  For example,  if a Fund agreed to exchange  payments in
dollars for  payments in foreign  currency,  in each case based on a fixed rate,
the swap  agreement  would tend to decrease a Fund's  exposure to U.S.  interest
rates and increase its exposure to foreign currency and interest rates. Caps and
floors have an effect  similar to buying or writing  options.  Depending  on how
they are used, swap  agreements may increase or decrease the overall  volatility
of a Fund's investments and its share price and yield.

Swap agreements are sophisticated  hedging  instruments that typically involve a
small  investment  of cash  relative to the  magnitude  of risks  assumed.  As a
result,  swaps can be highly  volatile and may have a  considerable  impact on a
Fund's  performance.  Swap  agreements  are  subject  to  risks  related  to the
counterparty's   ability  to   perform,   and  may   decline  in  value  if  the
counterparty's  creditworthiness  deteriorates. A Fund may also suffer losses if
it is unable to terminate  outstanding  swap  agreements  or reduce its exposure
through offsetting transactions.

Swaps, caps, floors and collars are highly specialized  activities which involve
certain risks. See the Statement of Additional Information on the risks involved
in these activities.

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

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

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

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

The  Fund  may  also  enter  into  options  on  the  yield  "spread,"  or  yield
differential,  between two  securities,  a  transaction  referred to as a "yield
curve"  option,  for hedging  and  non-hedging  (an effort to  increase  current
income) purposes. In contrast to other types of options, a yield curve option is
based on the difference between the yields of designated  securities rather than
the actual  prices of the  individual  securities,  and is settled  through cash
payments.  Accordingly, a yield curve option is profitable to the holder if this
differential  widens (in the case of a call) or narrows  (in the case of a put),
regardless  of  whether  the yields of the  underlying  securities  increase  or
decrease.  Yield curve options  written by the Fund will be covered as described
in the Statement of Additional  Information.  The trading of yield curve options
is subject to all the risks  associated with trading other types of options,  as
discussed  below  under  "Risk  Factors"  and in  the  Statement  of  Additional
Information.  In addition,  such options present risks of loss even if the yield
on one of the underlying  securities remains constant,  if the spread moves in a
direction or to an extent which was not anticipated.

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

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

OPTIONS ON FOREIGN  CURRENCIES:  The Fund may also purchase and write options on
foreign  currencies  ("Options  on  Foreign  Currencies")  for  the  purpose  of
protecting  against  declines in the dollar  value of portfolio  securities  and
against  increases in the dollar cost of  securities  to be acquired.  As in the
case of other  types of  options,  however,  the writing of an Option on Foreign
Currency will  constitute  only a partial hedge, up to the amount of the premium
received, and the Fund may be required to purchase or sell foreign currencies at
disadvantageous  exchange rates,  thereby incurring  losses.  The purchase of an
Option  on  Foreign   Currency  may   constitute  an  effective   hedge  against
fluctuations in exchange rates although,  in the event of rate movements adverse
to the Fund's position, it may forfeit the entire amount of the premium paid for
the option plus related  transaction  costs.  The Fund may also choose to, or be
required to, receive delivery of the foreign  currencies  underlying  Options on
Foreign  Currencies it has entered into.  Under certain  circumstances,  such as
where the Adviser  believes that the applicable  exchange rate is unfavorable at
the time the currencies are received or the Adviser  anticipates,  for any other
reason,  that the exchange rate will improve,  the Fund may hold such currencies
for an indefinite  period of time.  See  "Investment  Objectives and Policies --
Foreign  Securities" in the Statement of Additional  Information for information
on the risks associated with holding foreign currency.

FUTURES  CONTRACTS:  The Fund may enter into  contracts for the purchase or sale
for  future  delivery  of fixed  income  securities  or  foreign  currencies  or
contracts  based on indices of securities or currencies  (including any index of
U.S. or foreign  securities) as such  instruments  become  available for trading
("Futures  Contracts").  Such  transactions  will be  entered  into for  hedging
purposes,  in order to protect the Fund's current or intended  investments  from
the effects of changes in interest or exchange rates or declines in a securities
market,  as  well  as for  non-hedging  purposes,  to the  extent  permitted  by
applicable  law. The Fund will incur  brokerage fees when it purchases and sells
Futures  Contracts,  and  will be  required  to  maintain  margin  deposits.  In
addition, Futures Contracts entail risks. Although the Adviser believes that use
of such contracts  will benefit the Fund, if its  investment  judgment about the
general  direction  of  interest  or exchange  rates or a  securities  market is
incorrect,  the  Fund's  overall  performance  may be poorer  than if it had not
entered into any such  contract  and the Fund may realize a loss.  The Fund will
not enter into any Futures  Contract if immediately  thereafter the value of all
such  Futures  Contracts  would  exceed  50% of the value of its  total  assets.

OPTIONS ON FUTURES CONTRACTS: The Fund may purchase and write options on Futures
Contracts   ("Options  on  Futures  Contracts")  for  hedging  purposes  or  for
non-hedging  purposes to the extent  permitted by applicable  law.  Purchases of
Options  on  Futures  Contracts  may  present  less risk in  hedging  the Fund's
portfolio than the purchase or sale of the underlying  Futures  Contracts  since
the  potential  loss is  limited  to the  amount  of the  premium  plus  related
transaction  costs,  although  it may be  necessary  to  exercise  the option to
realize any profit,  which results in the  establishment of a futures  position.
The writing of Options on Futures Contracts, however, does not present less risk
than the trading of Futures  Contracts and will constitute only a partial hedge,
up to the  amount  of  the  premium  received.  In  addition,  if an  option  is
exercised, the Fund may suffer a loss on the transaction.

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

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

The Fund may also  invest in  securities  rated Ba or lower by  Moody's or BB or
lower by S&P or Fitch and comparable unrated securities (commonly known as "junk
bonds") to the extent described above. No minimum rating standard is required by
the  Fund.These  securities  are considered  speculative  and,  while  generally
providing  greater  income than  investments  in higher rated  securities,  will
involve  greater risk of principal  and income  (including  the  possibility  of
default or bankruptcy of the issuers of such securities) and may involve greater
volatility  of price  (especially  during  periods of  economic  uncertainty  or
change) than securities in the higher rating categories.  However,  since yields
vary over time,  no specific  level of income can ever be  assured.  These lower
rated high yielding fixed income  securities  generally tend to reflect economic
changes and short-term  corporate and industry  developments 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,  the  market's
perception of their credit quality, and the outlook for economic growth). 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 market for these lower
rated fixed income  securities may be less liquid than the market for investment
grade fixed income securities,  and judgment may at times play a greater role in
valuing  these  securities  than in the case of  investment  grade 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.  For a chart  indicating
the composition of the bond portion of the Fund's  portfolio for the fiscal year
ended  September  30,  1994,  with the debt  securities  separated  into  rating
categories,  see Appendix B to this Prospectus.  See the Statement of Additional
Information for more information on lower rated securities.

    OPTIONS,  FUTURES  CONTRACTS AND FORWARD  CONTRACTS:  Although the Fund will
enter  into  transactions  in  options,  Futures  Contracts,  Options on Futures
Contracts  and  Options  on  Foreign  Currencies  for  hedging  purposes,   such
transactions  nevertheless  involve  certain  risks.  For  example,  a  lack  of
correlation between the instrument  underlying an option or Futures Contract and
the assets being hedged, or unexpected adverse price movements, could render the
Fund's hedging strategy  unsuccessful and could result in losses.  The Fund also
may enter into transactions in options,  Futures  Contracts,  Options on Futures
Contracts and Forward Contracts for other than hedging purposes,  which involves
greater risk. In particular, such transactions may result in losses for the Fund
which are not offset by gains on other  portfolio  positions,  thereby  reducing
gross income.  In addition,  foreign currency markets may be extremely  volatile
from time to time. There also can be no assurance that a liquid secondary market
will exist for any contract  purchased or sold,  and the Fund may be required to
maintain a position until exercise or expiration,  which could result in losses.
The Statement of Additional Information contains a description of the nature and
trading mechanics of options,  Futures Contracts,  Options on Futures Contracts,
Forward Contracts and Options on Foreign  Currencies,  and includes a discussion
of the risks related to transactions therein.

Transactions   in  Forward   Contracts   may  be   entered   into  only  in  the
over-the-counter  market. Futures Contracts and Options on Futures Contracts may
be entered into on U.S.  exchanges  regulated by the Commodity  Futures  Trading
Commission and on foreign  exchanges.  In addition,  the  securities  underlying
options,  Futures  Contracts and Options on Futures Contracts traded by the Fund
will include both domestic and freign securities.

The risks of investing in foreign  securities  may be intensified in the case of
investments in emerging  markets.  Securities  prices in emerging markets can be
significantly  more  volatile than in the more  developed  nations of the world,
reflecting the greater  uncertainties of investing in less  established  markets
and  economies.  In  particular,   countries  with  emerging  markets  may  have
relatively  unstable  governments,   present  the  risk  of  nationalization  of
businesses,  restrictions on foreign ownership,  or prohibitions of repatriation
of assets,  and may have less  protection of property rights than more developed
countries. The economies of countries with emerging markets may be predominantly
based on only a few industries,  may be highly vulnerable to changes in local or
global trade  conditions,  and may suffer from extreme and volatile debt burdens
or  inflation  rates.  Local  securities  markets  may  trade a small  number of
securities  and may be unable to respond  effectively  to  increases  in trading
volume,  potentially making prompt liquidation of substantial holdings difficult
or impossible at times. Securities of issuers located in countries with emerging
markets  may have  limited  marketability  and may be subject to more  abrupt or
erratic price movements.

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

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

The Fund does not  intend to trade in  securities  for  short-term  profits  and
anticipates  that portfolio  securities  ordinarily will be held for one year or
longer.  However,  the Fund will effect trades whenever it believes that changes
in its portfolio securities are appropriate.

                                --------------
The  investment  objectives and policies  described  above,  including  Options,
Options on Foreign Currency, Futures Contracts, Options on Futures Contracts and
Forward  Contracts,  are not fundamental and may be changed without  shareholder
approval.  A change in the Fund's  investment  objectives may result in the Fund
having investment objectives different from the objectives which the shareholder
considered appropriate at the time of investment in that 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.

 5. MANAGEMENT OF THE FUND

INVESTMENT  ADVISER -- The Adviser  manages the Fund  pursuant to an  Investment
Advisory  Agreement,  dated  January 18, 1985 (the  "Advisory  Agreement").  The
Adviser provides the Fund with overall  investment  advisory and  administrative
services, as well as general office facilities. Richard E. Dahlberg has been the
Fund's portfolio manager since June, 1985. Mr. Dahlberg has been employed by the
Adviser since 1968. Subject to such policies as the Trustees may determine,  the
Adviser  makes  investment  decisions  for the  Fund.  For  these  services  and
facilities,  the Adviser  receives a management fee,  computed and paid monthly,
fixed by a formula  based  upon a  percentage  of the Fund's  average  daily net
assets plus a  percentage  of the Fund's  gross income other than gains from the
sale of securities.  The applicable percentages are reduced as assets and income
reach the following levels:

<TABLE>
<CAPTION>
                   ANNUAL RATE OF MANAGEMENT FEE                                     ANNUAL RATE OF MANAGEMENT FEE
                 BASED ON AVERAGE DAILY NET ASSETS                                       BASED ON GROSS INCOME
- -------------------------------------------------------------------  ----------------------------------------------
<S>                                                                  <C>        
.25% of the first $200 million                                       3.57% of the first $14 million
.212% of average daily net assets in excess of $200 million          3.04% of gross income in excess of $14 million
</TABLE>

For the Fund's  fiscal year ended  September 30, 1994,  MFS received  management
fees under the Advisory  Agreement of $9,315,310 (of which  $5,365,312 was based
on average daily net assets and $3,949,998 on gross income),  equivalent,  on an
annualized basis, to 0.37% of the Fund's average daily net assets.

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)/Sun  Life Series  Trust,  MFS
Institutional Trust, MFS Union Standard Trust, MFS Variable Insurance Trust, MFS
Municipal  Income Trust,  MFS Government  Markets Income Trust,  MFS Multimarket
Income Trust,  MFS  Intermediate  Income Trust,  MFS Charter  Income Trust,  MFS
Special Value 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.  MFS and its wholly-owned  subsidiary,  MFS Asset Management,
Inc., provide 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

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

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

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

<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. MFD, on behalf of the Fund, will
     pay a commission on purchases of $1 million or more.
</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 that month and
each subsequent month. Except as noted below, the CDSC on Class A shares will be
waived in the case of: (i)  exchanges  (except  that if the shares  acquired  by
exchange were then redeemed within 12 months of the initial purchase (other than
in connection  with subsequent  exchanges to other MFS Funds),  the charge would
not be waived);  (ii)  distributions  to  participants  from a  retirement  plan
qualified under section 401(a) of the Internal  Revenue Code of 1986, as amended
(the "Code") (a "Retirement Plan"), due to: (a) a loan from the plan (repayments
of loans, however, will constitute new sales for purposes of assessing the CDSC;
(b) "financial hardship" of the participant in the plan, as that term is defined
in Treasury Regulation Section  1.401(k)-1(d)(2),  as amended from time to time;
or (c) the death of a participant  in such a plan;  (iii)  distributions  from a
403(b)  plan  or  an  Individual   Retirement  Account  ("IRA")  due  to  death,
disability,  or  attainment  of age 59 1/2;  (iv)  tax-free  returns  of  excess
contributions  to an IRA; (v)  distributions  by other employee benefit plans to
pay  benefits;  and (vi) certain  involuntary  redemptions  and  redemptions  in
connection with certain automatic  withdrawals from a qualified retirement plan.
The CDSC on Class A shares will not be waived,  however,  if the retirement plan
withdraws from the Fund except if 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.  The CDSC on Class A 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 the Shareholder Servicing
Agent.  The  CDSC on  Class A  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 share accounts
maintained  by  the   Shareholder   Servicing  Agent  on  behalf  of  individual
participants in the Retirement Plan, provided that the Retirement Plan's sponsor
subscribes  to  the  MFS   Fundamental   401(k)   Plan(sm)  or  another  similar
recordkeeping  system made available by the  Shareholder  Servicing  Agent.  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.  MFD shall receive all CDSCs which it intends
to apply for the benefit of the Fund.

MFD 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 4% and MFD 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 a 36-month  period for  purchases of $1 million or
more)  or  other  special  purchase  programs.  A  description  of the  Right of
Accumulation, Letter of Intent and Group Purchases privileges by which the sales
charge may be reduced is set forth in the Statement of  Additional  Information.
In  addition,  MFD,  on behalf of the Fund and  pursuant  to the Fund's  Class A
Distribution  Plan,  will  pay  commissions  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; provided, however,
that MFD may pay a  commission,  on sales in excess  of $5  million  to  certain
retirement plans, of 1.00% to certain dealers which, at MFD's invitation,  enter
into an agreement  with MFD 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
MFD.  Purchases  of $1  million  or more for each  shareholder  account  will be
aggregated  over a 12-month period  (commencing  from the date of the first such
purchase) for purposes of determining the level of commissions to be paid during
that period with respect to such account.

Class A shares of the Fund may be sold at their net asset value to the  officers
of the  Trust,  to any of the  subsidiary  companies  of Sun Life,  to  eligible
Directors,  officers, employees (including retired employees) and agents of MFS,
Sun  Life  or  any  of  their  subsidiary  companies,  to  any  trust,  pension,
profit-sharing  or any other benefit plan for such persons,  to any trustees and
retired  trustees of any investment  company for which MFD serves as distributor
or principal underwriter,  and to certain family members of such individuals and
their spouses,  provided the shares will not be resold except to the Fund. Class
A shares of the Fund may be sold at net asset  value to any  employee,  partner,
officer  or  trustee of any  sub-adviser  to any MFS Fund and to certain  family
members  of such  individuals  and  their  spouses,  or to any  trust,  pension,
profit-sharing or other retirement 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 MFD or its affiliates,  to certain
family members of such employees or representatives and their spouses, or to any
trust, pension,  profit-sharing or other retirement plan for the sole benefit of
such employee or representative,  as well as to clients of MFS Asset Management,
Inc.  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. In addition,  Class A shares
of the Fund may be sold at net asset value in connection with the acquisition or
liquidation  of the assets of other  investment  companies  or personal  holding
companies.  Insurance company separate accounts may also purchase Class A shares
of the  Fund at  their  net  asset  value.  Class A  shares  of the  Fund may 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. Class A shares of the Fund may also be sold at
net asset value through the automatic investment of Class A and Class B periodic
distributions  which constitute required  withdrawals from qualified  retirement
plans.  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 MFD, 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  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 MFS 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 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 MFD, as follows: 1.00% on sales
up to $5 million,  plus 0.25% on the amount in excess of $5  million;  provided,
however,  that MFD may pay a  commission,  on sales in excess of $5  million  to
certain   retirement  plans,  of  1.00%  to  certain  dealers  which,  at  MFD's
invitation,  enter  into an  agreement  with MFD 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  MFD.  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  also 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.  Class A  shares  of the Fund  may be sold at net  asset  value
through the automatic  reinvestment of Class A and Class B  distributions  which
constitute required  withdrawals from qualified  retirement plans.  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 Class A shares
of  other  MFS  Funds  pursuant  to the  Distribution  Investment  Program  (see
"Shareholder  Services" in the  Statement of  Additional  Information).

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

*Class B shares  purchased from January 1, 1993 through August 31,1993,  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:

  Sixth ....................................................            1%
  Seventh and following ....................................            0%

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

The CDSC on Class B shares  will be  waived  upon the  death or  disability  (as
defined in section  72(m)(7) of the Code) of any investor,  provided the account
is registered (i) in the case of a deceased  individual,  solely in the deceased
individual's name, (ii) in the case of a disabled individual,  solely or jointly
in the disabled individual's name or (iii) in the name of a living trust for the
benefit of the deceased or disabled individual.  The CDSC on Class B shares will
also be waived in the case of  redemptions  of shares of the Fund  pursuant to a
systematic  withdrawal  plan.  In  addition,  the CDSC on Class B shares will be
waived in the case of distributions from an IRA, SAR-SEP or any other retirement
plan qualified under Section 401(a),  401(k) or 403(b) of the Code, due to death
or disability,  or in the case of required minimum  distributions  from any such
retirement plan due to attainment of age 70 1/2. The CDSC on Class B shares will
be waived in the case of  distributions  from a retirement  plan qualified under
Sections 401(a) or 401(k) 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 of the Fund will also be waived  upon  redemption  by
(i)  officers of the Trust,  (ii) any of the  subsidiary  companies of Sun Life,
(iii) eligible Directors,  officers, employees (including retired employees) and
agents of MFS, Sun Life or any of their  subsidiary  companies,  (iv) any trust,
pension,  profit-sharing  or any other  benefit plan for such  persons,  (v) any
trustees and retired trustees of any investment  company for which MFD 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 MFD, by certain
family  members of 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  representatives  and by clients of MFS Asset Management,  Inc.
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.  A retirement  plan  qualified  under Section 401(a) or 401(k) 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  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),  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 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 the Shareholder Servicing Agent. The CDSC
on Class 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 B share accounts  provided that the Retirement
Plan's  sponsor  subscribes to the MFS  Fundamental  401(k)  Plan(sm) or another
similar  recordkeeping system made available by the Shareholder Servicing Agent.
The 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  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.

CLASS C SHARES: Class C shares are offered at net asset value without an initial
sales  charge or a CDSC.  Class C shares do not  convert  to any other  class of
shares of the Fund. The maximum investment in Class C shares that may be made is
$5,000,000 per transaction.

Class C shares are not currently  available for purchase by any retirement  plan
qualified  under Sections  401(a) or 403(b) of the Code if the  retirement  plan
and/or the sponsoring  organization subscribe to the MFS FUNDamental 401(k) Plan
or another similar 401(a) or 403(b) recordkeeping  program made available by MFS
Service Center, Inc.

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 MFD. The Fund reserves the right to cease offering its
shares at any time.

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

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

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

MFD may enter into an agreement with  shareholders  who intend to make exchanges
among certain classes of certain MFS Funds (as determined by MFD) 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 MFD 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 MFD each reserve the right to request market timers to redeem
their shares at net asset value,  less any  applicable  CDSC, if either of these
restrictions is violated.

Securities  dealers  and other  financial  institutions  may  receive  different
compensation  with  respect to sales of Class A, Class B and Class C shares.  In
some instances, promotional incentives to dealers may be offered only to certain
dealers who have sold or may sell significant  amounts of Fund shares. From time
to time,  MFD may pay dealers  100% of the  applicable  sales charge on sales of
Class A shares of  certain  specified  MFS Funds  sold by such  dealer  during a
specified  sales period.  In addition,  MFD or its affiliates  may, from time to
time,  pay dealers  and  additional  commission  equal to 0.50% of the net asset
value of all of the Class B shares of certain  specified  MFS Funds sold by such
dealer during a specified sales period.  In addition,  from time to time MFD, at
its expense,  may provide  additional  commissions,  compensation or promotional
incentives  ("concessions")  to dealers which sell shares of the Fund. The staff
of the SEC has  indicated  that  dealers who receive  more than 90% of the sales
charge may be  considered  underwriters.  Such  concessions  provided by MFD may
include   financial   assistance  to  dealers  in  connection  with  preapproved
conferences  or  seminars,  sales or training  programs  for invited  registered
representatives,  payment for travel expenses,  including  lodging,  incurred by
registered representatives and members of their families or other invited guests
to various  locations for such seminars or training  programs,  seminars for the
public,  advertising and sales campaigns regarding one or more MFS Funds, and/or
other  dealer-sponsored  events.  In some  instances,  these  concessions may be
offered to dealers or only to certain dealers who have sold or may sell,  during
specified  periods,  certain minimum amounts of shares of the Fund. From time to
time,  MFD may make expense  reimbursements  for special  training of a dealer's
registered  representatives  in group  meetings  or to help pay the  expenses of
sales  contests.  In some  instances,  promotional  incentives to dealers may be
offered only to certain dealers who have sold or may sell significant amounts of
Fund shares.  Other  concessions  may be offered to the extent not prohibited by
the laws of any  state or any  self-regulatory  agency,  such as the  NASD.

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,  MFD believes that such Act should not
preclude  banks from  entering  into agency  agreements  with MFD (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. In addition, Class C
shares may be exchanged  for shares of MFS Money Market Fund 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
or all the shares in an account  (except that the minimum is $50 for accounts 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.). 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  details  concerning  this exchange
privilege and  prospectuses  for any of the other MFS Funds may be obtained from
investment dealers or the Shareholder Servicing Agent. A shareholder should read
the prospectus of the other MFS Fund and consider the  differences in objectives
and policies  before  making any  exchange.  For federal and  (generally)  state
income tax  purposes,  an exchange is treated as a sale of the shares  exchanged
and,  therefore,  an exchange could result in a gain or loss to the  shareholder
making the exchange.  Exchanges by telephone are automatically available to most
non- retirement plan accounts and certain retirement plan accounts.  For further
information regarding exchanges by telephone see "Redemptions By Telephone." The
exchange  privilege (or any aspect of it) may be changed or discontinued  and is
subject to certain  limitations,  including certain restrictions on purchases by
market timers.  Special procedures,  privileges and restrictions with respect to
exchanges  may apply to market  timers who enter into an agreement  with MFD, as
set forth in such agreement (see "Purchases").

REDEMPTIONS AND REPURCHASES
A  shareholder  may  withdraw all or any portion of the amount in his account on
any date on which the Fund is open for business by redeeming shares at their net
asset  value  or by  selling  such  shares  to the  Fund  through  a  dealer  (a
repurchase).  Since the net asset  value of  shares  of the  account  fluctuate,
redemptions or repurchases, which are taxable transactions, are likely to result
in gains or losses to the  shareholder.  When a shareholder  withdraws an amount
from his account,  the  shareholder  is deemed to have tendered for redemption a
sufficient  number of full and  fractional  shares in his  account  to cover the
amount  withdrawn.  The proceeds of a redemption or repurchase  will normally be
available within seven days,  except that 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 from the redemption date
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 share  certificate  must be  endorsed  by the  record
owner(s)  exactly as the  shares are  registered  and the  signature(s)  must be
guaranteed  in  the  manner  set  forth  below  under  the  caption   "Signature
Guarantee." In addition,  in some cases, "good order" may require the furnishing
of additional  documents.  The  Shareholder  Servicing Agent may make certain de
minimis exceptions to the above  requirements for redemption.  Within seven days
after  receipt of a redemption  request by the  Shareholder  Servicing  Agent in
"good  order," the Fund will make  payment in cash of the net asset value of the
shares next determined  after such redemption  request was received,  reduced by
the amount of any  applicable  CDSC and the amount of any income tax required to
be  withheld,  except  during  any  period in which the right of  redemption  is
suspended  or date of payment is  postponed  because  the  Exchange is closed or
trading on such Exchange is restricted or to the extent  otherwise  permitted by
the 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 MFD ON THE SAME DAY
BEFORE MFD 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.

GENERAL: 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
shareholders could incur  transaction,  tax or other charges when converting the
securities to cash.

Due to the relatively high cost of maintaining small accounts, the Fund reserves
the right to redeem  shares in any account at 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") in Class A
and B shares 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 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.

DISTRIBUTION PLANS
The Trustees have adopted separate  distribution  plans for Class A, Class B and
Class C 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  MFD 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 MFD may pay  expenses  on  behalf of the Fund
related to the distribution and servicing of Class A shares.  The expenses to be
paid by MFD on behalf of the Fund  include a service fee to  securities  dealers
which enter into a sales agreement with MFD 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. MFD
may from time to time  reduce the amount of the service fee paid for shares sold
prior to a certain date. Currently the service fee is reduced to 0.15% per annum
of the Fund's average daily net assets attributable to Class A shares for shares
sold prior to October 1, 1989. MFD may also retain a  distribution  fee of 0.10%
per annum 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 MFD's  obligations  under its  distribution  agreement  with the
Trust. MFD, however,  currently is suspending this 0.10% per annum  distribution
fee and will not in the  future  accept  payment  of this  fee  unless  it first
obtains the approval of the Board of Trustees.  In addition,  to the extent that
the  aggregate  of the  foregoing  fees does not  exceed  0.35% per annum of the
average daily net assets of the Fund attributable to Class A shares, the Fund is
permitted to pay other distribution-related  expenses,  including commissions to
dealers  and  payments  to  wholesalers  employed by MFD for sales at or above a
certain  dollar  level.  Fees payable  under the Class A  Distribution  Plan are
charged to, and therefore  reduce,  income allocated to Class A shares.  Service
fees may be  reduced  for a  securities  dealer  that is the holder or dealer of
record for an  investor  who owns shares of the Fund having a net asset value at
or above a certain  dollar  level.  Dealers may from time to time be required to
meet certain  criteria in order to receive  service fees.  MFD 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  MFD  or  its  affiliates  for  shareholder
accounts.  Certain  banks  and other  financial  institutions  that have  agency
agreements  with MFD will receive service fees that are the same as service fees
to dealers.

    CLASS B DISTRIBUTION  PLAN. The Class B Distribution  Plan provides that the
Fund will pay MFD 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
MFD a  service  fee of up to  0.25%  of the  Fund's  average  daily  net  assets
attributable to Class B shares (which MFD will in turn pay to securities dealers
which  enter  into a sales  agreement  with  MFD at a rate of up to 0.25% of the
Fund's  average  daily  net  assets  attributable  to  Class B  shares  owned by
investors  for whom that  securities  dealer is the holder or dealer of record).
This  service fee is intended to be  additional  consideration  for all personal
services and/or account maintenance services rendered by the dealer with respect
to Class B shares.  Fees payable under the Class B Distribution Plan are charged
to,  and  therefore  reduce,  income  allocated  to Class B shares.  The Class B
Distribution Plan also provides that MFD will receive all CDSCs  attributable to
Class B shares (see "Redemptions and Repurchases" above) which do not reduce the
distribution  fee. MFD will pay  commissions to dealers of 3.75% of the purchase
price of Class B shares  purchased  through  dealers.  MFD will also  advance to
dealers  the first year  service  fee at a rate  equal to 0.25% of the  purchase
price of such shares and, as compensation  therefor,  MFD may retain the service
fee paid by the Fund  with  respect  to such  shares  for the first  year  after
purchase.  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. MFD 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 MFD or its affiliates
for shareholder accounts.  The purpose of the distribution payments to MFD under
the Class B Distribution Plan is to compensate MFD for its distribution services
to the Fund. Since MFD's compensation is not directly tied to its expenses,  the
amount of compensation  received by MFD 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 MFD in excess of
the amount of compensation it receives.  The expenses incurred by MFD, 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 MFD will receive agency transaction and service fees
that are the same as commissions and service fees to dealers.

    CLASS C DISTRIBUTION  PLAN. The Class C Distribution  Plan provides that the
Fund will pay MFD a  distribution  fee of up to 0.75%  per  annum of the  Fund's
average  daily  net  assets  attributable  to Class C shares  and will pay MFD a
service  fee of up to 0.25% per annum of the  Fund's  average  daily net  assets
attributable  to Class C shares  (which MFD in turn pays to  securities  dealers
which enter into a sales  agreement  with MFD at a rate of up to 0.25% per annum
of the Fund's daily net assets attributable to Class C shares owned by investors
for whom that  securities  dealer  is the  holder  or  dealer  of  record).  The
distribution/service  fees attributable to Class C shares are designed to permit
an  investor  to  purchase  such  shares  through a  broker-dealer  without  the
assessment of an initial sales charge or a CDSC while allowing MFD to compensate
broker-dealers  in connection  with the sale of such shares.  The service fee is
intended to be additional consideration for all personal services and/or account
maintenance  services  rendered  with  respect  to  Class C  shares.  MFD or its
affiliates  are entitled to retain all service  fees  payable  under the Class C
Distribution  Plan with  respect  to  accounts  for which  there is no dealer of
record as partial consideration for personal services and/or account maintenance
services  performed  by MFD or its  affiliates  for  shareholder  accounts.  The
purpose of the distribution  payments paid to MFD under the Class C Distribution
Plan  is  to  compensate  MFD  for  its  distribution   services  to  the  Fund.
Distribution  payments  under  the  Plan  will be used by MFD to pay  securities
dealers a distribution fee in an amount equal on an annual basis to 0.75% of the
Fund's  average  daily  net  assets  attributable  to  Class C  shares  owned by
investors  for whom that  securities  dealer is the  holder or dealer of record.
(Therefore, the total amount of distribution/service fees paid to a dealer on an
annual basis is 1.00% of the Fund's  average  daily net assets  attributable  to
Class C shares owned by investors for whom the  securities  dealer is the holder
or dealer of record.)  MFD also pays  expenses  for  printing  prospectuses  and
reports used for sales  purposes,  expenses with respect to the  preparation and
printing of sales literature and other distribution related expenses, including,
without  limitation,  the  compensation  of  personnel  and all costs of travel,
office expense and equipment.  Since MFD's  compensation is not directly tied to
its expenses,  the amount of compensation received by MFD 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 MFD in excess of the amount of  compensation  it  receives.  Certain
banks and other financial institutions that have agency agreements with MFD will
receive agency  transaction  and service fees that are the same as  distribution
and service fees paid to dealers.  Fees payable  under the Class C  Distribution
Plan are charged to, and therefore reduce, income allocated to Class C shares.

DISTRIBUTIONS
The Fund intends to declare as dividends  daily and pay to its  shareholders  as
dividends monthly substantially all of its net investment income (dividends will
only accrue on shares for which payment has been received).  Dividends generally
are distributed on the first business day of the month. The Fund may make one or
more  distributions  during  the  calendar  year to its  shareholders  from  any
long-term capital gains and 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 made
(see "Tax Status" and  "Shareholder  Services -- Distribution  Options"  below).
Distributions  paid by the Fund with respect to Class A shares will generally be
greater  than  those  paid with  respect  to Class B and Class C shares  because
expenses attributable to Class B and Class C shares will generally be higher.

TAX STATUS
The Fund is treated as an entity separate from the other series of the Trust for
federal  income  tax  purposes.  In order to  minimize  the taxes the Fund would
otherwise  be  required  to pay,  the Fund  intends  to  qualify  each year as a
"regulated  investment  company"  under  Subchapter  M of the Code,  and to make
distributions  to its  shareholders in accordance  with the timing  requirements
imposed by the Code.  It is  expected  that the Fund will not be required to pay
entity level federal  income or excise  taxes,  although  foreign-source  income
received by the Fund may be subject to foreign  withholding taxes.

Shareholders of the Fund normally will have to pay federal income taxes (and any
state or local taxes) on dividends and capital gain distributions from the Fund,
whether paid in cash or additional  shares. A portion of the dividends  received
from the Fund (but none of the Fund's  capital gain  distributions)  may qualify
for the dividends-received deduction for corporations. A statement setting forth
the federal income tax status of all dividends and  distributions for that year,
including  the  portion  taxable as  ordinary  income,  the  portion  taxable as
long-term  capital gain, the portion  representing  interest on U.S.  Government
obligations,  the portion,  if any,  representing  a return of capital (which is
free of current taxes but results in a basis reduction), and the amount, if any,
of federal income tax withheld,  will be sent to each shareholder promptly after
the end of such year.

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

NET ASSET VALUE
The net asset value per share of each class of shares 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 liabilities  attributable to the class from the value of
the Fund's assets  attributable  to the class and dividing the difference by the
number of shares of the class  outstanding.  Assets in the Fund's  portfolio are
valued on the basis of their  market  values as  described  in the  Statement of
Additional Information. The net asset value of each class of shares is effective
for orders  received by the dealer prior to its  calculation and received by MFD
prior to the close of that business day.

DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES
The Fund, one of two series of the Trust, has three classes of shares,  entitled
Class A, Class B and Class C 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 that class.
Shares have no  pre-emptive  or conversion  rights (except as set forth above 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 (e.g.,  fidelity bonding and errors and omissions  insurance)  existed
and the Trust itself was unable to meet its obligations.

PERFORMANCE INFORMATION
From time to time, the Fund will provide yield,  current  distribution  rate and
total rate of return quotations for each class of shares and may also quote fund
rankings in the relevant fund category from various sources,  such as the Lipper
Analytical Services,  Inc. and Wiesenberger  Investment Companies Service. Yield
quotations are based on the annualized net investment income per share allocated
to each  class of the Fund  over a 30-day  period  stated  as a  percent  of the
maximum  public  offering  price of that  class on the last day of that  period.
Yield  calculations  for  Class B shares  assume  no CDSC is paid.  The  current
distribution  rate for each class is  generally  based upon the total  amount of
dividends  per share paid by the Fund to  shareholders  of that class during the
past 12 months and is computed by dividing  the amount of such  dividends by the
maximum public  offering price of that class at the end of such period.  Current
distribution  rate  calculations  for Class B shares assume no CDSC is paid. The
current  distribution  rate  differs from the yield  calculation  because it may
include  distributions  to  shareholders  from sources other than  dividends and
interest, such as premium income from option writing,  short-term capital gains,
and return of invested  capital,  and is calculated  over a different  period of
time. Total rate of return quotations will reflect the average annual percentage
change over stated periods in the value of an investment in each class of shares
of the Fund made at the  maximum  public  offering  price of the  shares of that
class with all distributions  reinvested and which, if quoted for periods of six
years or less,  will give effect to the  imposition  of the CDSC  assessed  upon
redemptions of the Fund's Class B shares.  Such total rate of return  quotations
may be accompanied by quotations  which do not reflect the reduction in value of
the initial investment due to the sales charge or the deduction of the CDSC, and
which will thus be higher.  All  performance  quotations are based on historical
performance and are not intended to indicate future performance.  Yield reflects
only net portfolio income as of a stated period of time and current distribution
rate  reflects  only the rate of  distributions  paid by the Fund  over a stated
period of time, while 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 yield, current distribution rate and total rate of return, see the Statement
of Additional Information.  For further information about the Fund's performance
for the fiscal  year ended  September  30,  1994,  please see the Fund's  Annual
Report. A copy of the Annual Report may be obtained without charge by contacting
the  Shareholder  Servicing Agent (see back cover for address and phone number).
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.

7.  SHAREHOLDER SERVICES
Shareholders with questions  concerning the shareholder services described below
or concerning other aspects of the Fund,  should contact their investment dealer
or 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  information  regarding
the tax status of reportable dividends and distributions for that year (see "Tax
Status" above).

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 in cash; 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 last  business  day of the  quarter.  Checks for
dividends  and  capital  gain  distributions  in  amounts  less  than  $10  will
automatically  be reinvested in additional  shares of the Fund. 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  shareholders's  distribution option will
automatically  be  converted  to having all  dividends  and other  distributions
reinvested in additional  shares.  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
trust) 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 any class of shares of that
shareholder  in the MFS  Funds  or MFS  Fixed  Fund (a bank  collective  trust),
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 (without a sales charge
and not subject to any applicable CDSC).

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

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

AUTOMATIC EXCHANGE PLAN: Shareholders having account balances of at least $5,000
in any MFS Fund may  exchange  their  shares for the same class of shares of the
other MFS Funds  (and,  in the case of Class C shares,  for  shares of MFS Money
Market Fund) under the Automatic Exchange Plan, a dollar cost averaging program.
The  Automatic  Exchange  Plan  provides  for  automatic  monthly  or  quarterly
exchanges of funds from the shareholder's  account in an MFS Fund for investment
in the same  class of shares of other MFS  Funds  selected  by the  shareholder.
Under the Automatic Exchange Plan, exchanges 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 exchange money
into such fund  through the  Automatic  Exchange  Plan.  No  transaction  fee is
imposed in connection with exchange  transactions  under the Automatic  Exchange
Plan.  However,  exchanges 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,  an  exchange  is  treated  as a sale  of the  shares  exchanged  and,
therefore,  could result in a capital gain or loss to the shareholder making the
exchange.  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 charge 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 -- Except as noted under  "Purchases  -- Class C
Shares,"  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.

                                                                      APPENDIX A
                         DESCRIPTION OF BOND RATINGS
The ratings of Moody's, S&P and Fitch represent their opinions as to the quality
of various debt instruments. IT SHOULD BE EMPHASIZED,  HOWEVER, THAT RATINGS ARE
NOT ABSOLUTE STANDARDS OF QUALITY. CONSEQUENTLY,  DEBT INSTRUMENTS WITH THE SAME
MATURITY,  COUPON AND RATING MAY HAVE DIFFERENT YIELDS WHILE DEBT INSTRUMENTS OF
THE SAME MATURITY AND COUPON WITH DIFFERENT RATINGS MAY HAVE THE SAME YIELD.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

NOTE:  Moody's applies  numerical  modifiers,  1, 2 and 3 in each generic rating
classification  from Aa to B. The modifier 1 indicates that the company ranks in
the higher end of its  generic  rating  category;  the  modifier 2  indicates  a
mid-range  ranking;  and the modifier 3 indicates  that the company ranks in the
lower end of its generic rating category.

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

AA: Debt rated "AA" has a 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.

                                    FITCH
AAA: Bonds  considered to be investment grade and of the highest credit quality.
The  obligor  has an  exceptionally  strong  ability to pay  interest  and repay
principal which is unlikely to be affected by reasonably foreseeable events.

AA: Bonds considered to be investment grade and of very high credit quality. The
obligor's  ability to pay interest and repay principal is very strong,  although
not quite as strong as bonds rated "AAA".  Because  bonds rated in the "AAA" and
"AA"  categories  are  not  significantly   vulnerable  to  foreseeable   future
developments, short-term debt of these issuers is generally rated "F-l + ".

A: Bonds considered to be investment grade and of very high credit quality.  The
obligor's  ability to pay  interest  and repay  principal  is  considered  to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

BBB: Bonds considered to be investment grade and of satisfactory credit quality.
The  obligor's  ability to pay interest and repay  principal is considered to be
adequate. Adverse changes in economic conditions and circumstances, however, are
more likely to have adverse impact on these bonds,  and therefore  impair timely
payment.  The  likelihood  that the  ratings  of these  bonds  will  fall  below
investment grade is higher than for bonds with higher ratings.

BB: Bonds are considered speculative.  The obligor's ability to pay interest and
repay principal may be affected over time by adverse economic changes.  However,
business and financial  alternatives  can be  identified  which could assist the
obligor in satisfying its debt service requirements.

B:  Bonds are  considered  highly  speculative.  While  bonds in this  class are
currently meeting debt service requirements, the probability of continued timely
payment of principal and interest  reflects the obligor's  limited margin safety
and the need for reasonable  business and economic activity  throughout the life
of the issue.

CCC: Bonds have certain identifiable  characteristics which if not remedied, may
lead to  default.  The  ability to meet  obligations  requires  an  advantageous
business and economic environment.

CC: Bonds are minimally protect. Default in payment of interest and/or principal
seems probable over time.

C: Bonds are in imminent default in payment of interest or principal.

PLUS (+ ) MINUS  (-):  Plus and minus  signs  are used  with a rating  symbol to
indicate the relative position of a credit within the rating category.  Plus and
minus signs, however, are not used in the "AAA" category.

R: Indicates that Fitch does not rate the specific issue.

CONDITIONAL:  A conditional rating is premised on the successful completion of a
project or the occurrence of a specific event.

SUSPENDED:  A rating is  suspended  when Fitch  deems the amount of  information
available from the issuer to be inadequate for rating purposes.

WITHDRAWN:  A rating  will be  withdrawn  when an issue  matures or is called or
refinanced and at Fitch's  discretion when an issuer fails to furnish proper and
timely information.

FITCHALERT:  Ratings  are  placed  on  FitchAlert  to  notify  investors  of  an
occurrence that is likely to result in a rating change and the likely  direction
of such  change.  These are  designated  as  "Positive",  indicating a potential
upgrade,  "Negative", for potential downgrade, or "Evolving",  where ratings may
be lowered,  FitchAlert is relatively short-term,  and should be resolved within
12 months.
