- ----------
<FN>
<F1> Purchases of $1 million or more are not subject to an initial sales charge;  however,  a contingent  deferred sales charge (a
     "CDSC") of 1% will be imposed on such purchases in the event of certain  redemption  transactions  within 12 months following
     such purchases (see "Purchases" below).
<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,  0.10% of the distribution/service fee is being waived. After a substantial period of time, distribution
     expenses paid under this Plan,  together  with the initial  sales  charge,  may total more than the maximum sales charge that
     would have been permissible if imposed entirely as an initial sales charge.
<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 permissible if imposed entirely as an initial sales charge.

EXAMPLE OF EXPENSES
- -------------------

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

  PERIOD                      CLASS A         CLASS B          CLASS C
  ------                      -------   --------------------   -------

  10 years ...............     162        193\2/      193\2/    208

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

The purpose of the expense  table is to assist  investors in  understanding  the
various costs and expenses that a shareholder  of the Fund will bear directly or
indirectly. More complete descriptions of the following expenses of the Fund 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
The Fund is a diversified series of the Trust, an open-end management investment
company  which  was  organized  as a  business  trust  under  the  laws  of  The
Commonwealth  of  Massachusetts  in 1977.  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 then uses
the  proceeds  to  buy  securities  (primarily  bonds  and  other  fixed  income
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 CDSC in the case of certain  purchases of $1
million or more) and subject to a Distribution Plan providing for a distribution
and  service  fee.  Class B shares  are  offered at net asset  value  without an
initial sales charge but subject to a CDSC and a Distribution Plan providing for
a  distribution  and service fee which are greater than the Class A distribution
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  and  service  fee which are equal to the
Class B annual  distribution  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. MFS is the Fund's investment  adviser.  A majority of the Trustees are not
affiliated  with the Adviser.  The Adviser is responsible  for the management of
the assets of the Fund and the  officers  of the Trust are  responsible  for the
Fund's  operations.  The  Adviser  manages  the  portfolio  from  day  to day in
accordance with the Fund's investment  objective and policies.  The selection of
investments  and the way they are managed depend on the conditions and trends in
the economy  and the  financial  marketplaces.  The Fund also offers to buy back
(redeem) its shares from its  shareholders at any time at their net asset value,
less any applicable CDSC.

4.  INVESTMENT OBJECTIVE AND POLICIES

   
INVESTMENT  OBJECTIVE  -- The  investment  objective of the Fund is to seek high
current income by investing  primarily in a professionally  managed  diversified
portfolio of fixed income securities, some of which may involve equity features.
Capital growth,  if any, is a  consideration  incidental to the objective of the
Fund of high current  income.  Any investment  involves risk and there can be no
assurance that the Fund will achieve its investment objective.

INVESTMENT  POLICIES -- Fixed income securities offering the high current income
sought by the Fund normally include those fixed income  securities which offer a
current  yield above that  generally  available on debt  securities in the three
highest rating categories of the recognized  rating agencies  (commonly known as
"junk bonds" if rated below the four highest  categories  of  recognized  rating
agencies).  However,  since available yields and yield  differentials  vary over
time, no specific level of income or yield differential can ever be assured. The
dividends  paid by the Fund will  increase or decrease in relation to the income
received by the Fund from its investments, which would in any case be reduced by
the expenses of the Fund before such income is distributed to its  shareholders.
For a description of these rating categories, see Appendix A to this Prospectus,
and for a chart  indicating  the  composition  of the bond portion of the Fund's
portfolio for its fiscal year ended January 31, 1995,  with the debt  securities
separated  into  rating  categories,  see  Appendix  B to this  Prospectus  (see
"Investment  Objective  and Policies -- Risk Factors of Lower Rated  Securities"
below for a description  of the risks involved in investing in these lower rated
fixed income securities).
    

Fixed income securities include preferred and preference stocks and all types of
debt  obligations  of  both  domestic  and  foreign  issuers,   such  as  bonds,
debentures,  notes,  equipment lease certificates,  equipment trust certificates
(including interests in trusts or other entities representing such obligations),
conditional  sales  contracts,   commercial  paper  and  obligations  issued  or
guaranteed  by the  U.S.  Government,  any  foreign  government  or any of their
respective  political  subdivisions,  agencies or  instrumentalities  (including
obligations, such as repurchase agreements, secured by such instruments).

Corporate debt  securities  may bear fixed,  fixed and  contingent,  or variable
rates of  interest  and may  involve  equity  features,  such as  conversion  or
exchange  rights  or  warrants  for the  acquisition  of  stock of the same or a
different issuer;  participations  based on revenues,  sales or profits;  or the
purchase of common stock in a unit transaction  (where corporate debt securities
and common stock are offered as a unit).  Under normal  market  conditions,  not
more than 25% of the value of the total  assets of the Fund will be  invested in
equity securities, including common stocks, warrants and rights.

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  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.

   
COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTICLASS PASS-THROUGH SECURITIES:  The
Fund may invest a portion of its assets in collateralized  mortgage  obligations
("CMOs"),  which  are  debt  obligations  collateralized  by  mortgage  loans or
mortgage  pass-through  securities  (such  collateral  collectively  hereinafter
referred  to as  "Mortgage  Assets").  The Fund may also invest a portion of its
assets in multiclass  pass-through  securities  which are equity  interests in a
trust composed of Mortgage Assets.  Unless the context indicates otherwise,  all
references herein to CMOs include multiclass pass-through  securities.  Payments
of principal of and interest on the Mortgage Assets,  and any reinvested  income
thereon,  provide  the funds to pay debt  service on the CMOs or make  scheduled
distributions on the multiclass  pass-through  securities.  In CMOs, a series of
bonds or  certificates  are usually  issued in multiple  classes with  different
maturities.  Each class of CMOs, often referred to as a "tranch", is issued at a
specific  fixed or  floating  coupon  rate and has a  stated  maturity  or final
distribution  date.  Principal  prepayments on the Mortgage Assets may cause the
CMOs to be retired  substantially  earlier then their stated maturities or final
distribution dates,  resulting in a loss of all or a part of the premium, if any
has been  paid.  The  Fund may also  invest  in  parallel  pay CMOs and  Planned
Amortization  Class CMOs ("PAC  Bonds").  Parallel  pay CMOs are  structured  to
provide  payments of principal on each payment date to more than one class.  PAC
Bonds  generally  require  payments of a specified  amount of  principal on each
payment date. PAC Bonds are always parallel pay CMOs with the required principal
payment on such securities  having the highest  priority after interest has been
paid to all classes.  For a further  description  of CMOs,  see the Statement of
Additional Information.
    

STRIPPED MORTGAGE-BACKED SECURITIES: The Fund may invest a portion of its assets
in stripped mortgage-backed securities,  which are derivative securities usually
structured with two classes that receive  different  proportions of the interest
and principal  distributions  from an underlying pool of Mortgage Assets.  For a
further discussion of stripped mortgage-backed  securities and the risks related
to transactions therein, see the Statement of Additional Information.

   
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.

FOREIGN  SECURITIES:  The Fund may invest up to 50% (and  expects  generally  to
invest between 5% and 20%) of its total assets in foreign  securities  which are
not traded on a U.S.  exchange (not including ADRs).  Investing in securities of
foreign  issuers  generally  involves  risks  not  ordinarily   associated  with
investing in securities of domestic  issuers.  These include changes in currency
rates, exchange control regulations,  governmental administration or economic or
monetary  policy (in the United States or abroad) or  circumstances  in dealings
between nations.  Costs may be incurred in connection with  conversions  between
various  currencies.  Special  considerations  may  also  include  more  limited
information about foreign issuers,  higher brokerage costs, different accounting
standards and thinner trading markets.  Foreign  securities  markets may also be
less liquid,  more volatile and less subject to government  supervision  than in
the United States.  Investments in foreign  countries could be affected by other
factors   including   expropriation,   confiscatory   taxation   and   potential
difficulties  in  enforcing  contractual  obligations  and could be  subject  to
extended  settlement  periods.  The Fund may hold foreign  currency  received in
connection with  investments in foreign  securities when, in the judgment of the
Adviser,  it would be beneficial to convert such currency into U.S. dollars at a
later date, based on anticipated changes in the relevant exchange rate. The Fund
may also hold foreign currency in anticipation of purchasing foreign securities.
The Fund may invest in foreign  securities  without limitation and has authority
to invest up to 25% of its total assets in  securities  issued or  guaranteed by
foreign governments or their agencies or  instrumentalities.  However,  the Fund
has made  commitments  to regulatory  authorities  to limit its  investments  in
securities issued by any single foreign government to 5% of its total assets and
to continue to maintain its status as a diversified company under the Investment
Company  Act of  1940,  as  amended  (the  "1940  Act").  See the  Statement  of
Additional  Information  for further  discussion of foreign  securities  and the
holding of foreign currency, as well as the associated risks.
    

The Fund may  invest up to 40% of the  value of its total  assets in each of the
electric utility and telephone industries,  but will not invest more than 25% in
either of those industries unless yields available for four consecutive weeks in
the four highest  rating  categories on new issue bonds in such industry  (issue
size of $50  million or more) have  averaged  in excess of 105% of yields of new
issue long-term  industrial  bonds similarly rated (issue size of $50 million or
more) and, in the opinion of the Adviser, the relative return available from the
electric  utility or telephone  industry and the relative  risk,  marketability,
quality and  availability  of  securities  of such  industry  justifies  such an
investment.

During  periods of unusual  market  conditions  when the Adviser  believes  that
investing for defensive  purposes is  appropriate,  part or all of the assets of
the Fund may be invested in cash  (including  foreign  currency)  or  short-term
money market instruments including, but not limited to, certificates of deposit,
commercial paper, short-term notes, obligations issued or guaranteed by the U.S.
Government  or  any  of  its  agencies  or   instrumentalities   and  repurchase
agreements.

When and if available,  fixed income  securities  may be purchased at a discount
from face value.  However,  the Fund does not intend to hold such  securities to
maturity for the purpose of achieving  potential  capital gains,  unless current
yields on these  securities  remain  attractive.  From time to time the Fund may
purchase  securities not paying interest at the time acquired if, in the opinion
of the Adviser,  such securities have the potential for future income or capital
appreciation.

   
EMERGING MARKET SECURITIES:  Consistent with the Fund's investment objective and
policies and its ability to invest in foreign 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;
or (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.

The risks of investing in foreign  securities  may be intensified in the case of
investments in emerging markets.  Securities of many issuers in emerging markets
may be less liquid and more  volatile than  securities  of  comparable  domestic
issuers.   Emerging  markets  also  have  different   clearance  and  settlement
procedures,  and in certain markets there have been times when  settlements have
been unable to keep pace with the volume of securities  transactions,  making it
difficult to conduct such  transactions.  Delays in  settlement  could result in
temporary  periods when a portion of the assets of the Fund is uninvested and no
return is earned  thereon.  The inability of the Fund to make intended  security
purchases due to  settlement  problems  could cause the Fund to miss  attractive
investment  opportunities.  Inability to dispose of portfolio  securities due to
settlement  problems could result either in losses to the Fund due to subsequent
declines in value of the  portfolio  security or, if the Fund has entered into a
contract to sell the security,  in possible liability to the purchaser.  Certain
markets may require payment for securities before delivery. 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.

Certain emerging markets may require governmental  approval for the repatriation
of investment income,  capital or the proceeds of sales of securities by foreign
investors.  In  addition,  if a  deterioration  occurs in an  emerging  market's
balance of payments  or for other  reasons,  a country  could  impose  temporary
restrictions  on  foreign  capital  remittances.  The Fund  could  be  adversely
affected by delays in, or a refusal to grant, any required governmental approval
for  repatriation  of capital,  as well as by the application to the Fund of any
restrictions on investments.

Investment  in certain  emerging  market debt  obligations  may be restricted or
controlled  to varying  degrees.  These  restrictions  or controls  may at times
preclude investment in certain emerging market debt obligations and increase the
expenses of the Fund.

BRADY BONDS:  The Fund may invest in Brady Bonds,  which are securities  created
through the  exchange of  existing  commercial  bank loans to public and private
entities  in certain  emerging  markets  for new bonds in  connection  with debt
restructurings  under  a debt  restructuring  plan  introduced  by  former  U.S.
Secretary of the Treasury, Nicholas F. Brady (the "Brady Plan"). Brady Plan debt
restructurings  have been  implemented to date in Argentina,  Brazil,  Bulgaria,
Costa Rica,  Ecuador,  Mexico,  Nigeria,  the Philippines,  Poland,  Uruguay and
Venezuela.  Brady Bonds have been issued only  recently,  and for that reason do
not  have  a  long  payment  history.  Brady  Bonds  may  be  collateralized  or
uncollateralized,  are  issued in various  currencies  (but  primarily  the U.S.
dollar) and are actively  traded in  over-the-counter  secondary  markets.  U.S.
dollar-denominated, collateralized Brady Bonds, which may be fixed rate bonds or
floating-rate  bonds,  are generally  collateralized  in full as to principal by
U.S.  Treasury  zero coupon bonds having the same  maturity as the bonds.  Brady
Bonds  are  often  viewed  as having  three or four  valuation  components:  the
collateralized  repayment  of principal at final  maturity;  the  collateralized
interest   payments;   the   uncollateralized   interest   payments;   and   any
uncollateralized  repayment  of principal  at maturity  (these  uncollateralized
amounts  constituting  the  "residual  risk").  In light of the residual risk of
Brady Bonds and the history of defaults of  countries  issuing  Brady Bonds with
respect to commercial bank loans by public and private entities,  investments in
Brady Bonds may be viewed as speculative.

RISK  FACTORS OF LOWER RATED  SECURITIES:  Securities  offering the high current
income  sought by the Fund are  ordinarily  in the lower  rating  categories  of
recognized  rating  agencies  (that  is,  ratings  of Baa or  lower  by  Moody's
Investors Service, Inc. ("Moody's") or BBB or lower by Standard & Poor's Ratings
Group ("S&P") or Fitch Investors Service, Inc. ("Fitch")) or are unrated and, as
described  below,  generally  involve  greater  volatility  of price and risk of
principal  and  income  than   securites  in  the  higher   rating   categories.
Accordingly,  an  investment  in  shares of the Fund  should  not  constitute  a
complete  investment  program and may not be appropriate for all investors.  The
Fund, however, seeks to reduce risk through diversification, credit analysis and
attention to current  developments  and trends in both the economy and financial
markets.  In addition,  investments  in foreign  securities may serve to provide
further diversification.

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 fixed income 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").  No minimum  rating  standard  is required by the Fund.
These  securities are considered  speculative  and,  while  generally  providing
greater income than investments in higher rated securities, will involve greater
risk of principal and income (including the possibility of default or bankruptcy
of the issuers of such  securities) and may involve greater  volatility of price
(especially during periods of economic uncertainty or change) than securities in
the higher  rating  categories  and because  yields vary over time,  no specific
level of income can ever be  assured.  These  lower  rated high  yielding  fixed
income  securities  generally  tend to be affected by economic  changes (and the
outlook for economic growth), short-term corporate and industry developments and
the market's  perception  of their credit  quality  (especially  during times of
adverse publicity) to a greater extent than higher rated securities, which react
primarily to fluctuations in the general level of interest rates (although these
lower  rated  securities  are also  affected  by  changes in  interest  rates as
described  below).  In the past,  economic  downturns or an increase in interest
rates have, under certain circumstances, caused a higher incidence of default by
the issuers of these  securities and may do so in the future,  especially in the
case of highly leveraged issuers.  During certain periods,  the higher yields on
the Fund's lower rated high yielding fixed income  securities are paid primarily
because of the increased risk of loss of principal and income, arising from such
factors as the heightened possibility of default or bankruptcy of the issuers of
such securities.  Due to the fixed income payments of these securities, the Fund
may continue to earn the same level of interest income while its net asset value
declines  due to  portfolio  losses,  which  could  result in an increase in the
Fund's  yield  despite  the  actual  loss of  principal.  The  prices  for these
securities  may be affected by  legislative  and  regulatory  developments.  For
example, new federal rules require that savings and loan associations  gradually
reduce their holdings of high-yield  securities.  An effect of such  legislation
may be to depress  the prices of  outstanding  lower rated high  yielding  fixed
income securities.  The market for these lower rated fixed income securities may
be less liquid than the market for  investment  grade fixed  income  securities.
Furthermore,  the liquidity of these lower rated  securities  may be affected by
the  market's  perception  of their credit  quality.  Therefore,  the  Adviser's
judgment may at times play a greater role in valuing  these  securities  than in
the case of investment  grade fixed income  securities,  and it also may be more
difficult during times of certain adverse market  conditions to sell these lower
rated  securities  to meet  redemption  requests or to respond to changes in the
market.
    

While the  Adviser  may refer to ratings  issued by  established  credit  rating
agencies,  it is not the Fund's policy to rely  exclusively on ratings issued by
these rating agencies,  but rather to supplement such ratings with the Adviser's
own independent and ongoing review of credit quality.  The Fund's achievement of
its  investment  objective  may be more  dependent on the  Adviser's  own credit
analysis than in the case of an investment company primarily investing in higher
quality fixed income securities.

   
Because  shares  of  the  Fund  represent  an  investment  in  securities   with
fluctuating  market prices,  shareholders  should  understand  that the value of
shares of the Fund will vary as the aggregate value of the portfolio  securities
of the Fund increases or decreases.  However, changes in the value of securities
subsequent to their acquisition will not affect cash income or yield to maturity
to the Fund.
    

The net asset value of the shares of an open-end investment company, such as the
Fund, which invests primarily in fixed income securities, changes as the general
levels of interest rates fluctuate.  When interest rates decline, the value of a
portfolio  invested at higher yields can be expected to rise.  Conversely,  when
interest  rates rise,  the value of a portfolio  invested at lower yields can be
expected to decline.

The Fund seeks to maximize the return on its  portfolio  by taking  advantage of
market developments, yield disparities and variations in the creditworthiness of
issuers.  This may result in increases or decreases in the current income of the
Fund available for  distribution to its  shareholders  and in the holding by the
Fund of debt  securities  which sell at  moderate  to  substantial  premiums  or
discounts from face value.  Moreover,  if the Fund's  expectations of changes in
interest  rates or its evaluation of the normal yield  relationship  between two
securities  proves to be  incorrect,  the income,  net asset value and potential
capital gain of the Fund may be decreased or its  potential  capital loss may be
increased.

MORTGAGE PASS-THROUGH  SECURITIES:  The Fund may invest in mortgage pass-through
securities.   Mortgage  pass-through   securities  are  securities  representing
interests  in "pools" of  mortgage  loans.  Monthly  payments  of  interest  and
principal by the  individual  borrowers on mortgages  are passed  through to the
holders of the  securities  (net of fees paid to the issuer or  guarantor of the
securities) as the mortgages in the underlying  mortgage pools are paid off. The
average lives of mortgage  pass-throughs  are variable when issued because their
average lives depend on prepayment  rates.  The average life of these securities
is likely to be  substantially  shorter than their  stated  final  maturity as a
result of unscheduled principal prepayment.  Prepayments on underlying mortgages
result in a loss of  anticipated  interest,  and all or part of a premium if any
has been  paid,  and the  actual  yield  (or  total  return)  to the Fund may be
different  than  the  quoted  yield  on  the  securities.  Mortgage  prepayments
generally increase with falling interest rates and decrease with rising interest
rates. Like other fixed income securities, when interest rates rise the value of
a mortgage pass-through security generally will decline;  however, when interest
rates  are  declining,  the  value  of  mortgage  pass-through  securities  with
prepayment  features  may not  increase  as much as that of other  fixed  income
securities.

   
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 indexes,  currencies,  and 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 the Fund's investment  exposure from one type
of investment to another.  For example,  if the Fund agreed to exchange payments
in dollars  for  payments in a foreign  currency,  in each case based on a fixed
rate,  the swap  agreement  would tend to decrease  the 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 the 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 the
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. The 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.
    

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  PORTFOLIO  SECURITIES:  The Fund may seek to increase  its income by
lending  portfolio  securities.  Such loans will usually be made to member firms
(and  subsidiaries  thereof) of the New York Stock Exchange (the "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.  Treasury
securities  maintained  on a current  basis at an  amount at least  equal to the
market  value  of the  securities  loaned.  If the  Adviser  determines  to make
securities  loans, it is intended that the value of the securities  loaned would
not exceed 30% of the value of the total assets of the Fund.

LOANS AND OTHER DIRECT INDEBTEDNESS: The Fund may invest a portion of its assets
in "loans." By purchasing a loan,  the Fund acquires some or all of the interest
of a bank or other lending institution in a loan to a corporate  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 loans
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.  Loans 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 loans and the risks related to transactions therein,
see the Statement of Additional Information.

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.

"WHEN-ISSUED"  SECURITIES:  The Fund may purchase  some  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  short-term  securities  that  offer  same- day
settlement and earnings.

   
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 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.

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.
    
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 a Fund's  limitation  on investing  not
more than 15% of its net assets in illiquid investments,  or liquid and thus not
subject to such  limitation.  The Board of Trustees has adopted  guidelines  and
delegated to 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 the 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.

OPTIONS:  The Fund may write (sell)  "covered"  put and call options on domestic
and foreign fixed income  securities.  Call options written by the Fund give the
holder  the  right  to buy the  underlying  securities  from the Fund at a fixed
exercise  price  up to a stated  expiration  date  or,  in the  case of  certain
options,  on such  date.  Put  options  give the  holder  the  right to sell the
underlying  security  to the  Fund  during  the  term of the  option  at a fixed
exercise  price  up to a stated  expiration  date  or,  in the  case of  certain
options, on such date. Call options are "covered" by the Fund, for example, when
it owns the  underlying  securities,  and put options are "covered" by the Fund,
for example,  when it has established a segregated  account of cash,  short-term
money  market  instruments  and  high  quality  debt  securities  which  can  be
liquidated  promptly  to satisfy  any  obligation  of the Fund to  purchase  the
underlying securities.  The Fund may also write straddles  (combinations of puts
and  calls  on  the  same  underlying  security).   Such  transactions  generate
additional premium income but also include greater risk.

The Fund will  receive  a  premium  from  writing  a put or call  option,  which
increases the Fund's gross income in the event the option expires unexercised or
is closed out at a profit.  The amount of the premium will reflect,  among other
things,  the  relationship  of the  exercise  price  to  the  market  price  and
volatility of the underlying security,  the remaining term of the option, supply
and demand and interest  rates.  By writing a call  option,  the Fund limits its
opportunity  to profit from any increase in the market  value of the  underlying
security  above the exercise price of the option.  By writing a put option,  the
Fund  assumes  the risk  that it may be  required  to  purchase  the  underlying
security  for an exercise  price  higher  than its then  current  market  value,
resulting  in  a  potential  capital  loss  unless  the  security   subsequently
appreciates in value.

The Fund may terminate an option that it has written prior to its  expiration by
entering  into a closing  purchase  transaction  in which it purchases an option
having the same terms as the  option  written.  It is  possible,  however,  that
illiquidity  in the options  markets may make it difficult from time to time for
the Fund to close out its written option positions.

The Fund may also  purchase  put or call options in  anticipation  of changes in
interest  rates which may  adversely  affect the value of its  portfolio  or the
prices of  securities  that the Fund  wants to  purchase  at a later  date.  The
premium paid for a put or call option plus any transaction costs will reduce the
benefit,  if any, realized by the Fund upon exercise of the option,  and, unless
the price of the underlying security changes sufficiently, the option may expire
without value to the Fund.

The Fund may write and  purchase  options  on  securities  not only for  hedging
purposes,  but also  for the  purpose  of  increasing  its  return.  Options  on
securities that are written or purchased by the Fund will be traded on U.S.
and foreign exchanges and over-the-counter.

The Fund may also enter into options on the yield "spread" or yield differential
between  two fixed  income  securities,  a  transaction  referred to as a "yield
curve" option, for hedging and non-hedging  purposes. In contrast to other types
of options,  a yield curve option is based on the difference  between the yields
of  designated  fixed  income  securities  rather than the actual  prices of the
individual securities. Yield curve options written by the Fund will be "covered"
but could involve  additional risks, as discussed in the Statement of Additional
Information.

The staff of the  Securities and Exchange  Commission  (the "SEC") has taken the
position  that  purchased  over-the-counter  options  and  assets  used to cover
written  over-the-counter  options are illiquid  and,  therefore,  together with
other illiquid  securities held by the Fund, cannot exceed a certain  percentage
of the Fund's  assets  (the "SEC  illiquidity  ceiling").  Although  the Adviser
disagrees with this position, the Adviser intends to limit the Fund's writing of
over-the-counter  options in accordance with the following procedure.  Except as
provided  below,  the Fund intends to write  over-the-counter  options only with
primary U.S.  Government  securities  dealers  recognized as such by the Federal
Reserve Bank of New York.  Also, the contracts  which the Fund has in place with
such primary  dealers provide that the Fund has the absolute right to repurchase
an  option it writes at any time at a price  which  represents  the fair  market
value, as determined in good faith through negotiation between the parties,  but
which in no event will  exceed a price  determined  pursuant to a formula in the
contract.  Although  the  specific  formula  may  vary  between  contracts  with
different  primary dealers,  the formula generally is based on a multiple of the
premium received by the Fund for writing the option, plus the amount, if any, of
the option's intrinsic value (i.e., the amount that the option is in-the-money).
The formula may also include a factor to account for the difference  between the
price of the  security  and the  strike  price of the  option  if the  option is
written  out-of-the-money.  The Fund will treat all or a portion of the  formula
price as illiquid for purposes of the SEC illiquidity ceiling. The Fund may also
write  over-the-counter  options with  non-primary  dealers,  including  foreign
dealers,  and will treat the assets used to cover these  options as illiquid for
purposes of the SEC illiquidity ceiling.

FUTURES  CONTRACTS AND OPTIONS ON FUTURES  CONTRACTS:  The Fund may purchase and
sell futures contracts on fixed income securities or indices of such securities,
including  municipal  bond  indices  and  any  other  indices  of  fixed  income
securities which may become  available for trading  ("Futures  Contracts").  The
Fund may also purchase and write options on such Futures Contracts  ("Options on
Futures Contracts"). These instruments will be used to hedge against anticipated
future changes in interest rates which otherwise might either  adversely  affect
the value of the Fund's  portfolio  securities or adversely affect the prices of
securities  which the Fund intends to purchase at a later date.  Should interest
rates move in an  unexpected  manner,  the Fund may not achieve the  anticipated
benefits of the hedging  transactions  and may realize a loss. The Fund may also
purchase  and sell  Futures  Contracts  and  Options  on Futures  Contracts  for
non-hedging purposes, subject to applicable law, which involves greater risk and
could result in losses which are not offset by gains on other portfolio assets.

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

The Fund has adopted the  additional  restriction  that it will not enter into a
Futures Contract if, immediately  thereafter,  the value of securities and other
obligations  underlying all such Futures Contracts would exceed 50% of the value
of the Fund's total  assets.  Moreover,  the Fund will not purchase put and call
options on securities,  on Futures Contracts or on foreign  currencies,  if as a
result, more than 5% of its total assets would be invested in such options.

Futures  Contracts and Options on Futures Contracts that are entered into by the
Fund will be traded on U.S. and foreign exchanges.

   
FORWARD  CONTRACTS:  The Fund may enter into forward foreign  currency  exchange
contracts ("Forward Contracts") to attempt to minimize the risk to the Fund from
adverse  changes  in the  relationship  between  the  U.S.  dollar  and  foreign
currencies.  A Forward  Contract is an obligation to purchase or sell a specific
currency for an agreed price at a future date which is  individually  negotiated
and privately traded by currency traders and their customers. The Fund may enter
into a Forward  Contract,  for  example,  when it enters into a contract for the
purchase  or sale of a security  denominated  in a foreign  currency in order to
"lock in" the U.S. dollar price of the security. Additionally, for example, when
the Fund  believes  that a foreign  currency  may suffer a  substantial  decline
against the U.S. dollar,  it may enter into a Forward Contract to sell an amount
of that foreign  currency  approximating  the value of some or all of the Fund's
portfolio securities denominated in such foreign currency.  Conversely, when the
Fund believes that the U.S.  dollar may suffer a substantial  decline  against a
foreign  currency,  it may enter  into a Forward  Contract  to buy that  foreign
currency  for a fixed  dollar  amount.  The Fund may also  enter  into a Forward
Contract on one  Currency in order 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 the General  Statement of Policy of the
SEC concerning such purchases.  Since that policy  currently  recommends that an
amount of the Fund's assets equal to the amount of the purchase be held aside or
segregated to be used to pay for the commitment, the Fund will always have cash,
high quality debt securities or cash equivalents  available  sufficient to cover
any  commitments  under these  contracts  or to limit any  potential  risk.  The
segregated  account will be marked to market on a daily basis. The Fund may also
be  required  to,  or may elect  to,  receive  delivery  of  foreign  currencies
underlying  Forward  Contracts,  which may involve  certain risks.  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 -- Additional
Risk  Factors"  below.  The  Fund has  established  procedures  consistent  with
statements of the SEC and its staff  regarding  the use of Forward  Contracts by
registered investment companies,  which requires the use of segregated assets or
"cover" in connection with the purchase and sale of such contracts.

OPTIONS  ON FOREIGN  CURRENCIES:  The Fund may  purchase  and write put and call
options on foreign  currencies for the purpose of protecting against declines in
the dollar value of foreign  portfolio  securities and against  increases in the
dollar cost of foreign securities to be acquired.  As in the case of other kinds
of  options,  however,  the  writing  of an  option  on  foreign  currency  will
constitute only a partial hedge, up to the amount of the premium  received,  and
the  Fund  could  be  required  to  purchase  or  sell  foreign   currencies  at
disadvantageous  exchange rates,  thereby incurring  losses.  The purchase of an
option  on  foreign   currency  may   constitute  an  effective   hedge  against
fluctuations in exchange rates although,  in the event of rate movements adverse
to the Fund's  position,  it may forfeit the entire  amount of the premium  plus
related transaction costs. Options on foreign currencies written or purchased by
the Fund will be traded on U.S. and foreign exchanges and over-the-counter.  The
Fund may also be  required  to, or may elect to,  receive  delivery  of  foreign
currency  underlying  options on foreign  currencies,  which may involve certain
risks. See Additional Risk Factors" below.
    

ADDITIONAL RISK FACTORS:  Although the Fund will enter into certain transactions
in options, Futures Contracts,  Options on Futures Contracts,  Forward Contracts
and  options on foreign  currencies  for  hedging  purposes,  such  transactions
nevertheless  involve  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  option
transactions  and Futures  Contracts and Options on Futures  Contracts for other
than hedging purposes, which involves greater risk. In addition, there can be no
assurance that a liquid secondary  market will exist for any contract  purchased
or sold,  and the Fund may be required to maintain a position  until exercise or
expiration,   which  could  result  in  losses.   The  Statement  of  Additional
Information  contains  a further  description  of  options,  Futures  Contracts,
Options  on  Futures  Contracts,   Forward  Contracts  and  options  on  foreign
currencies,  and a  discussion  of the risks  related to  transactions  therein.
Transactions  entered into for  non-hedging  purposes  involve  greater risk and
could result in losses which are not offset by gains on other portfolio assets.

As a result of its  investments  in  foreign  securities,  the Fund may  receive
interest or dividend payments, or the proceeds of the sale or redemption of such
securities,  in the foreign  currencies in which such securities are denominated
which creates a currency  exchange rate risk. The Fund may also choose to, or be
required  to,  receive  delivery of the foreign  currencies  underlying  Forward
Contracts and 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. While the holding of
currencies will permit the Fund to take advantage of favorable  movements in the
applicable exchange rate, such strategy also exposes the Fund to risk of loss if
exchange rates move in a direction  adverse to the Fund's position.  Such losses
could reduce any profits or increase  any losses  sustained by the Fund from the
sale or redemption  of securities  and could reduce the dollar value of interest
or dividend payments received.

Transactions  in  options  may be  entered  into by the  Fund on  United  States
exchanges  regulated by the SEC, in the  over-the-counter  market and on foreign
exchanges,   while   Forward   Contracts   may  be  entered  into  only  in  the
over-the-counter  market. Futures Contracts and Options on Futures Contracts may
be entered into on United States exchanges  regulated by the CFTC and on foreign
exchanges.  In addition, the securities underlying options and Futures Contracts
traded by the Fund may include foreign as well as domestic securities. Investing
in foreign securities and trading in foreign markets involve  considerations and
possible risks not typically associated with investing in domestic securities or
entering  into  transactions  on  domestic  exchanges.   The  value  of  foreign
securities investments will be affected by changes in currency rates or exchange
control  regulations,  changes in  governmental  administration  or  economic or
monetary policy (in this country or abroad) or changed circumstances in dealings
between nations.  Costs may be incurred in connection with  conversions  between
various  currencies.  Moreover,  foreign  issuers are not subject to accounting,
auditing and financial reporting standards and requirements  comparable to those
of  domestic  issuers.  Securities  and  other  instruments  issued or traded in
foreign  countries  may be less liquid and more  volatile  than those  issued or
traded in the United  States and foreign  brokerage  commissions  are  generally
higher than in the United States.  Foreign securities and foreign markets may be
less subject to governmental  supervision than in the United States, and foreign
exchanges may impose different exercise and settlement  procedures.  Investments
in foreign  countries  could be  affected  by other  factors  not present in the
United  States,  including  expropriation,  confiscatory  taxation and potential
difficulties  in  enforcing  contractual  obligations  and could be  subject  to
extended settlement periods.  Over-the-counter transactions also involve certain
risks which may not be present in exchange-traded transactions.

   
PORTFOLIO  TRADING:  The primary  consideration  in placing  portfolio  security
transactions  is execution at the most  favorable  prices.  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 as a factor in the selection
of broker-dealers  to execute the portfolio  transactions of the Fund. 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 policies  described  above are not  fundamental  and may be changed  without
shareholder approval, as may the investment objective of the Fund.

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



5.  MANAGEMENT OF THE FUND

   
INVESTMENT  ADVISER -- MFS manages the Fund pursuant to an  Investment  Advisory
Agreement, dated May 20, 1987 (the "Advisory Agreement").  MFS provides the Fund
with overall investment advisory and administrative services, as well as general
office  facilities.  Robert J. Manning,  a Senior Vice President of the Adviser,
has become the Fund's  portfolio  manager.  Mr. Manning has been employed by the
Adviser since 1984. Subject to such policies as the Trustees may determine,  the
Adviser  makes  investment  decisions  for the  Fund.  For  these  services  and
facilities,  MFS receives a management  fee,  computed and paid monthly,  on the
basis of a formula  based upon a percentage  of the average  daily net assets of
the Fund plus a percentage  of its gross income  (i.e.,  income other than gains
from the sale of  securities or gains  received from futures  contracts) in each
case on an annualized  basis for the  then-current  fiscal year of the Fund. The
applicable  percentages  are  reduced as assets and income  reach the  following
levels:

0.187% of average daily net assets in excess of $200 million        2.55% of gross income in excess of $22  million
</TABLE>

   
For the Fund's fiscal year ended January 31, 1995, MFS received  management fees
under the Advisory Agreement of $3,756,072.

approximately  $35.4  billion on behalf of  approximately  1.7 million  investor
accounts as of April 28, 1995.  As of such date,  the MFS  organization  managed
approximately  $19  billion  of assets in fixed  income  funds and fixed  income
portfolios of MFS Asset Management, Inc. MFS is a wholly owned subsidiary of Sun
Life of Canada  (U.S.)  which in turn is a wholly owned  subsidiary  of Sun Life
Assurance  Company of Canada  ("Sun  Life").  The  Directors of MFS are A. Keith
Brodkin, Jeffrey L. Shames, Arnold D. Scott, John R. Gardner and John D. McNeil.
Mr.  Brodkin is the  Chairman,  Mr. Shames is the President and Mr. Scott is the

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 financial institutions may also 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:

<FN>
- ----------
<F1> Because of rounding in the  calculation  of offering  price,  actual sales charges may be more or less than those  calculated
     using the percentages above.
   
<F2> A CDSC may apply in certain circumstances.  MFD (on behalf of the Fund) will also 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 may be  imposed  on such
investments in the event of a share  redemption  within 12 months  following the
share  purchase,  at the rate of 1% of the  lesser  of the  value of the  shares
redeemed  (exclusive of reinvested  dividends and capital gain distributions) or
the total cost of such shares.

In determining whether a CDSC on such Class A shares is payable, and, if so, the
amount of the charge,  it is assumed that shares not subject to the CDSC are the
first redeemed followed by other shares held for the longest period of time. All
investments  made during a calendar  month,  regardless of when during the month
the  investment  occurred,  will age one  month on the last day of the month and
each subsequent month. Except as noted below, the CDSC on Class A shares will be
waived in the case of: (i)  exchanges  (except  that if the shares  acquired  by
exchange were then redeemed within 12 months of the initial purchase (other than
in connection with subsequent exchanges to other MFS Funds) the charge would not
be waived);  (ii) distributions to participants from a Retirement Plan qualified
under  section  401(a) of the  Internal  Revenue  Code of 1986,  as amended (the
"Code") (a "Retirement  Plan"),  due to: (a) a loan from the plan (repayments of
loans,  however,  will constitute new sales for purposes of assessing the CDSC);
(b) "financial hardship" of the participant in the plan, as that term is defined
in Treasury Regulation Section  1.401(k)-1(d)(2),  as amended from time to time;
or (c) the death of a participant  in such a plan;  (iii)  distributions  from a
403(b)  plan  or  an  Individual   Retirement  Account  ("IRA")  due  to  death,
disability,  or  attainment  of age 59 1/2;  (iv)  tax-free  returns  of  excess
contributions  to an IRA; (v)  distributions  by other employee benefit plans to
pay  benefits  and (vi)  certain  involuntary  redemptions  and  redemptions  in
connection with certain automatic  withdrawals from a qualified retirement plan.
The CDSC on Class A shares will not be waived,  however,  if the Retirement Plan
withdraws from the Fund except if that  Retirement  Plan has invested its assets
in Class A shares of one or more of the MFS  Funds  for more than 10 years  from
the later to occur of (i) January 1, 1993 or (ii) the date such  Retirement Plan
first invests its assets in Class A shares of one or more of the MFS Funds,  the
CDSC on Class A shares will be waived in the case of a redemption  of all of the
Retirement  Plan's shares (including shares of any other class) in all MFS Funds
(i.e.,  all the  assets of the  Retirement  Plan  invested  in the MFS Funds are
withdrawn),  unless,  immediately prior to the redemption,  the aggregate amount
invested by the  Retirement  Plan in Class A shares of the MFS Funds  (excluding
the reinvestment of distributions)  during the prior four year period equals 50%
or more of the total value of the Retirement  Plan's assets in the MFS Funds, in
which  case the  CDSC  will not be  waived.  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 also be reduced is set forth in the  Statement  of  Additional
Information. In addition, MFD, pays a commission to dealers who initiate and are
responsible for purchases of $1 million or more as follows: 1.00% on sales up to
$5 million,  plus 0.25% on the amount in excess of $5 million.  Purchases  of $1
million or more for each shareholder  account will be aggregated over a 12-month
period  (commencing  from the date of the first such  purchase)  for purposes of
determining  the level of commissions to be paid during that period with respect
to such account.

Class A shares of the Fund may be sold at their net asset value to the  officers
of the  Trust,  to any of the  subsidiary  companies  of Sun Life,  to  eligible
Directors,  officers, employees (including retired employees) and agents of MFS,
Sun  Life  or  any  of  their  subsidiary  companies,  to  any  trust,  pension,
profit-sharing  or any other benefit plan for such persons,  to any trustees and
retired  trustees of any investment  company for which MFD serves as distributor
or  principal  underwriter,  and to certain  family  members of such persons and
their spouses,  provided the shares will not be resold except to the Fund. Class
A shares of the Fund may be sold at net asset  value to any  employee,  partner,
officer  or  trustee of any  sub-adviser  to any MFS Fund and to certain  family
members  of such  individuals  and  their  spouses,  or to any  trust,  pension,
profit-sharing or other retirement plan for the sole benefit of such employee or
representative,  provided  such  shares  will not be resold  except to the Fund.
Class A shares  of the Fund may  also be sold at their  net  asset  value to any
employee  or  registered   representative  of  any  dealer  or  other  financial
institution  which has a sales agreement with 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 also be sold at net  asset  value  where  the  amount  invested
represents  redemption  proceeds from the MFS Fixed Fund.  In addition,  Class A
shares  of the  Fund  may be sold at net  asset  value  in  connection  with the
acquisition  or  liquidation  of the  assets of other  investment  companies  or
personal holding  companies.  Insurance  company separate  accounts may purchase
Class A shares of the Fund at their net asset value per share. 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 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 be  purchased  at net asset  value by  Retirement
Plans 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 a percentage of the lesser of the original
purchase price or redemption proceeds as follows:

  YEAR OF                                                      CONTINGENT

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  sections  401(a)  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 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
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 Fund,  (ii) any of the subsidiary
companies of Sun Life, (iii) eligible Directors,  officers,  employees,  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 any such employee or representative  and their
spouses or by any trust,  pension,  profit-sharing  or other retirement plan for
the sole benefit of such employee or representative  and by clients of MFS Asset
Management,  Inc.  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 the
Shareholder Servicing Agent.

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.  In
addition,  from time to time, MFD may pay dealers 100% of the  applicable  sales
charge on sales of Class A shares of  certain  specified  MFS Funds sold by such
dealer during a specified sales period. In addition,  MFD or its affiliates may,
from time to time,  pay dealers an additional  commission  equal to 0.50% of the
net asset value of all of the Class B shares of certain specified 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. Other concessions may be offered to the extent not prohibited by
the laws of the 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 at net asset value (if available for sale). In addition, Class C
shares may be  exchanged  for shares of the 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
($50 in the case of retirement plan participants whose sponsoring  organizations
subscribe  to  the  MFS  FUNDamental  401(k)  Plan  or  another  similar  401(k)
recordkeeping  system made available by the Shareholder  Servicing Agent) or all
the shares in the account. If an Exchange Request is received by the Shareholder
Servicing Agent on any business day prior to the close of regular trading on the
New York Stock  Exchange (the  "Exchange"),  the exchange  usually will occur on
that day if all the requirements set forth above have been complied with at that
time.  No more than five  exchanges  may be made in any one Exchange  Request by
telephone.   Additional  information  concerning  this  exchange  privilege  and
prospectuses  for any of the other MFS Funds  may be  obtained  from  investment
dealers or the  Shareholder  Servicing  Agent.  A  shareholder  should  read the
prospectus of the other MFS Fund and consider the  differences in objectives and
policies before making any exchange.  For federal and  (generally)  state income
tax  purposes,  an  exchange is treated as a sale of the shares  exchanged  and,
therefore,  an exchange could result in a gain or loss to the shareholder making
the exchange.  Exchanges by telephone are  automatically  available to most non-
retirement  plan  accounts and certain  retirement  plan  accounts.  For further
information  regarding  exchanges by telephone,  see "Redemptions by Telephone".
The exchange  privilege (or any aspect of it) may be changed or discontinued and
is subject to certain  limitations,  including certain restrictions on purchases
by market timers.  Special procedures,  privileges and restrictions with respect
to exchanges may apply to market timers who enter into an agreement with 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).  Certain purchases,  however, may be subject to a CDSC in the event
of certain  redemption  transactions  (see  "Contingent  Deferred  Sales Charge"
below).  Since  the  net  asset  value  of  shares  of the  account  fluctuates,
redemptions or repurchases, which are taxable transactions, are likely to result
in gains or losses to the  shareholder.  When a shareholder  withdraws an amount
from his account,  the  shareholder  is deemed to have tendered for redemption a
sufficient  number of full and  fractional  shares in his  account  to cover the
amount  withdrawn.  The proceeds of a redemption or repurchase  will normally be
available within seven days, except for shares purchased or received in exchange
for shares purchased by check (including  certified checks or cashier's checks).
Payment  of  redemption  proceeds  may be  delayed  for up to 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  letter  of  instruction,  together  with his share
certificates  (if any were  issued),  all in "good  order" for  transfer.  "Good
order"  generally  means that the stock power,  written  request for redemption,
letter of  instruction or  certificate  must be endorsed by the record  owner(s)
exactly as the shares are registered and the signature(s)  must be guaranteed in
the manner set forth below under the caption "Signature Guarantee." In addition,
in some cases "good order" will 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 in "good order" by the Shareholder  Servicing Agent, the Fund
will make  payment in cash of the net asset value of the shares next  determined
after  such  redemption  request  was  received,  reduced  by the  amount of any
applicable  CDSC described above and the amount of any income tax required to be
withheld, except during any period in which the right of redemption is suspended
or date of payment is  postponed  because  the  Exchange is closed or trading on
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 the  Shareholder  Servicing Agent 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 BEFORE THE CLOSE OF
BUSINESS  ON THE SAME DAY,  THE  SHAREHOLDER  WILL  RECEIVE  THE NET ASSET VALUE
CALCULATED  ON THAT DAY,  REDUCED BY THE AMOUNT OF ANY  APPLICABLE  CDSC AND THE
AMOUNT OF ANY INCOME TAX REQUIRED TO BE WITHHELD.

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 securities
(instead of cash) from the Fund's portfolio.  The securities distributed in such
a  distribution  would be valued at the same amount as that  assigned to them in
calculating  the net asset  value for the shares  being sold.  If a  shareholder
received a  distribution  in kind,  the  shareholder  could incur  brokerage  or
transaction charges when converting the securities to cash.

Due to the relatively high cost of maintaining small accounts, the Fund reserves
the right to redeem  shares in any account for their  then-current  value (which
will be promptly paid to the shareholder) if at any time the total investment in
such  account  drops below $500  because of  redemptions,  except in the case of
accounts being 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.

   
SIGNATURE  GUARANTEE:  In order to protect  shareholders  to the greatest extent
possible  against  fraud,  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.
    

CONTINGENT  DEFERRED  SALES CHARGE --  Investments  in Class A or Class B shares
("Direct Purchases") will be subject to a CDSC for a period of 12 months (in the
case of  purchases of $1 million or more of Class A shares) or six years (in the
case of purchases of Class B shares).  Purchases of Class A shares made during a
calendar  month,  regardless of when during the month the  investment  occurred,
will age one month on the last day of the month and each subsequent month. Class
B shares  purchased on or after January 1, 1993 will be aggregated on a calendar
month 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 a particular class, (i) any Free Amount
is not  subject to the CDSC and (ii) the amount of the  redemption  equal to the
then-current  value of Reinvested  Shares is not subject to the CDSC,  but (iii)
any amount of the  redemption  in excess of the  aggregate  of the  then-current
value of  Reinvested  Shares and the Free Amount is subject to a CDSC.  The CDSC
will first be applied  against the amount of Direct  Purchases which will result
in any such charge being  imposed at the lowest  possible  rate.  The CDSC to be
imposed  upon  redemptions  of  shares  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%  per annum 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 for
shares sold prior to a certain date. Currently,  the service fee paid to dealers
is reduced to 0.15% per annum for shares  purchased  prior to March 1, 1991. 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 Fund.  MFD,  however,  is currently
waiving  this 0.10% per annum  distribution  fee and will not 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%  per annum 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% per
annum of the  Fund's  average  daily net assets  attributable  to Class B shares
owned by investors  for whom that  securities  dealer is the holder or dealer of
record).  This service fee is intended to be  additional  consideration  for all
personal  services and/or account  maintenance  services  rendered by the dealer
with respect to Class B shares. Fees payable under the Class B Distribution Plan
are charged to, and therefore  reduce,  income allocated to Class B shares.  The
Class B  Distribution  Plan  also  provides  that 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% per annum
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 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 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% per annum 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  of  printing  prospectuses  and
reports used for sales  purposes,  expenses with respect to the  preparation and
printing of sales literature and other distribution related expenses, including,
without  limitation,  the  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
fees and service fees 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 daily and pay to its shareholders  substantially all
of its  net  investment  income  as  dividends  on a  monthly  basis.  Dividends
generally are  distributed on the first business day of the following  month. In
addition,  the Fund will 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.  All  distributions  not paid in cash will be
reinvested in shares of the class in which the  distribution  is paid. (see "Tax
Status" and "Shareholder Services -- Distribution Options" below). Distributions
paid by the Fund with  respect to Class A shares will  generally be greater than
those  paid  with  respect  to  Class B 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
any 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.  The  Fund  expects  that  its
distributions  will  not,  for the most  part,  be  eligible  for the  dividends
received deduction for corporations.

Shortly after the end of each calendar year, each Fund  shareholder will receive
a  statement  setting  forth the  federal  income  status of all  dividends  and
distributions for that year, including any portion,  taxable as ordinary income,
the portion,  if any,  taxable as long-term  capital gain, the portion,  if any,
representing a return of capital (which is generally free of current taxes,  but
results in a basis  reduction),  and the amount,  if any, of federal  income tax
withheld.

Fund   distributions   will  reduce  the  Fund's  net  asset  value  per  share.
Shareholders  who buy shares shortly before the Fund makes a distribution of net
capital  gains or net  short-term  capital gains may thus pay the full price for
the shares and then effectively  receive a portion of the purchase price back as
a taxable distribution.

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

Prospective  investors should read the Fund's Account Application for additional
information  regarding  backup  withholding  of  federal  income  tax and should
consult  their  own  tax  advisers  as to the  tax  consequences  to  them of an
investment in the Fund.

NET ASSET VALUE
The net asset value per share of each class of the Fund is  determined  each day
during which the Exchange is open for trading.  This  determination is made once
each day as of the close of regular  trading on the  Exchange by  deducting  the
amount of the liabilities attributable to the class from the value of the Fund's
assets  attributable  to the class and dividing the  difference by the number of
shares of the class  outstanding.  Assets in the Fund's  portfolio are valued on
the basis of valuations  furnished by a pricing  service or at their fair value,
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 shares of that  particular
series.  Shareholders are entitled to one vote for each share held and shares of
each series would be entitled to vote separately to approve investment  advisory
agreements or changes in investment restrictions, but shares of all series would
vote  together  in the  election  of  Trustees  and  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 its 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 any 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,  the  shareholders of each class
would be entitled to share pro rata in its 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  will be based on the  annualized  net  investment  income  per share
allocated to each class of the Fund over a 30-day  period stated as a percent of
the maximum public  offering price of that class on the last day of that period.
Yield  calculations  for  Class B shares  assume  no CDSC is paid.  The  current
distribution  rate for each class is  generally  based upon the total  amount of
dividends  per share paid by the Fund to  shareholders  of that class during the
past twelve  months and is computed by dividing the amount of such  dividends by
the  maximum  public  offering  price of that  class at the end of such  period.
Current  distribution  rate  calculations  for Class B shares  assume no CDSC is
paid. The current  distribution rate differs from the yield calculation  because
it may include  distributions to shareholders  from sources other than dividends
and interest,  such as premium income from option  writing,  short-term  capital
gains, and return of invested capital, and is calculated over a different period
of time.  Total  rate of return  quotations  will  reflect  the  average  annual
percentage  change over  stated  periods in the value of an  investment  in each
class of shares of the Fund made at the maximum public  offering price of shares
of that class with all distributions reinvested and which, if quoted for periods
of six years or less,  will give effect to the  imposition  of the CDSC assessed
upon  redemptions  of the  Fund's  Class B  shares.  Such  total  rate of return
quotations may be  accompanied by quotations  which do not reflect the reduction
in value of the initial investment due to the sales charge or the deduction of a
CDSC, and which will thus be higher. All performance  quotations of the Fund are
based  on  historical  performance  and  are not  intended  to  indicate  future
performance.  Yield  reflects only net portfolio  income as of a stated 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 quotations of
the Fund 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 January 31, 1995, 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  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 all reportable  dividends and distributions for that year (see
"Tax Status").

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

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

   
    -- Dividends in cash; capital gain distributions  (except as provided below)
       reinvested in additional shares.
    

    -- Dividends and capital gain distributions in cash.

   
With  respect  to the  second  option,  the  Fund  may  from  time to time  make
distributions  from  short-term  capital  gains on a monthly  basis,  and to the
extent  such gains are  distributed  monthly,  they  shall be paid in cash;  any
remaining  short-term  capital gains not so  distributed  shall be reinvested in
additional shares.

Reinvestments  (net of any tax withholding)  will be made in additional full and
fractional  shares of the same class of shares at the net asset  value in effect
at the close of  business  on the  record  date.  Dividends  and  capital  gains
distributions  in amounts  less than $10 will  automatically  be  reinvested  in
additional shares of the Fund. If a shareholder has elected to receive dividends
and/or  capital  gain  distributions  in cash and the  postal or other  delivery
service is unable to deliver checks to the shareholder's address of record, such
shareholder's  distribution option will automatically be converted to 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
Class B or Class C shares of the Fund or any of the  classes  of other MFS Funds
or MFS Fixed Fund within a 13-month  period (or 36-month period for purchases of
$1 million or more),  the  shareholder may obtain such shares of the Fund at the
same reduced sales charge as though the total quantity were invested in one lump
sum,  subject  to escrow  agreements  and the  appointment  of an  attorney  for
redemptions from the escrow amount if the intended  purchases are not completed,
by completing the Letter of Intent section of the Account Application.

    RIGHT OF  ACCUMULATION:  A  shareholder  qualifies for  cumulative  quantity
discounts on purchases of Class A shares when his new investment,  together with
the current  offering  price  value of all  holdings of the Class A, Class B and
Class C shares of that shareholder in the MFS Funds or MFS Fixed Fund, reaches a
discount level.
    

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

   
    SYSTEMATIC  WITHDRAWAL  PLAN:  A  shareholder  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 any CDSC
and  generally are 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.  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  charges
included  in shares  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 advisers before establishing any of the tax-deferred  retirement plans
described above.

                                                                   APPENDIX A

                      DESCRIPTION OF BOND RATINGS

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

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

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

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

                    STANDARD & POOR'S RATINGS GROUP
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 very strong capacity to pay interest and repay principal
and differs from the higher rated issues only in small degree.

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

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

BB, B, CCC, CC AND C: Debt rated BB, B, CCC, CC and C is  regarded,  on balance,
as predominantly  speculative with respect to capacity to pay interest and repay
principal in  accordance  with the terms of the  obligation.  BB  indicates  the
lowest degree of speculation and C the highest degree of speculation. While such
debt will likely have some  quality and  protective  characteristics,  these are
outweighed by large uncertainties or major risk exposures to adverse conditions.

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
rating 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 INVESTORS SERVICE, INC.
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- 1+".

A: Bonds  considered  to be  investment  grade and of 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,  however, are more likely to
have adverse  impact on these bonds,  and therefor  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 of
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  protected.  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.

NR: 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  unlikely  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 raised or  lowered.  FitchAlert  is  relatively  short-term,  and
should be resolved within 12 months.

                                 Trust  III  (the  "Trust"),   a   Massachusetts

                                 Fund.
    

2.  INVESTMENT OBJECTIVE, POLICIES AND RESTRICTIONS

INVESTMENT  OBJECTIVE.  The Fund's investment  objective is to seek high current
income by investing primarily in a professionally  managed diversified portfolio
of fixed income securities,  some of which may involve equity features.  Capital
growth,  if any, is a consideration  incidental to the objective of high current
income.  There can be no  assurance  that the Fund will  achieve its  investment
objective.

INVESTMENT POLICIES. The fixed income and other securities in which the Fund may
invest and the risks  associated  with such  investments  are  described  in the
Fund's Prospectus. The following policies are not fundamental and may be changed
without shareholder approval as may the Fund's investment objective.

   
RESTRICTED SECURITIES: The Fund may invest in restricted securities of companies
which the Adviser believes have significant  growth potential.  These securities
are subject to legal or contractual restrictions on resale. Consequently,  there
is no public trading market for these  securities and market  quotations are not
readily  available.  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.  The Fund may not  invest  more than 15% of its net  assets in
restricted  securities  (as  described  in the Fund's  investment  restrictions)
(restricted  securities  the Board of Trustees has determined are liquid are not
included in this amount). See "Investment  Objective,  Policies and Restrictions
- -- Investment Restrictions."

The Fund will not (a) invest more than 5% of its assets,  taken at market value,
in warrants  not acquired in a unit  transaction  or (b) invest more than 15% of
its assets,  taken at market value, in securities for which there are no readily
available market quotations.

LOANS AND  OTHER  DIRECT  INDEBTEDNESS:  The Fund may  purchase  loans and other
direct claims against a borrower. In purchasing loans, 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, although some may be unsecured.
Such  loans may be in  default  at the time of  purchase.  Loans  that are fully
secured offer the Fund more  protection  than an unsecured  loan in the event of
non-payment of scheduled interest or principal.  However,  there is no assurance
that the  liquidation  of  collateral  from a secured  loan  would  satisfy  the
corporate borrower's obligation, or that the collateral can be liquidated.
    

These  loans  are  made   generally  to  finance   internal   growth,   mergers,
acquisitions,   stock  repurchases,   leveraged  buy-outs  and  other  corporate
activities.   Such  loans  are   typically   made  by  a  syndicate  of  lending
institutions,  represented by an agent lending  institution which has negotiated
and structured the loan and is responsible  for collecting  interest,  principal
and other  amounts  due on its own  behalf  and on  behalf of the  others in the
syndicate,  and for enforcing  its and their other rights  against the borrower.
Alternatively, such loans may be structured as a novation, pursuant to which the
Fund would assume all of the rights of the lending  institution in a loan, or as
an  assignment,  pursuant to which the Fund would  purchase an  assignment  of a
portion of a lender's  interest  in a loan  either  directly  from the lender or
through  an  intermediary.  The  Fund may also  purchase  trade or other  claims
against  companies,  which  generally  represent  money 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  loans  acquired  by  the  Fund  may  involve  revolving  credit
facilities or other standby financing commitments which obligate the Fund to pay
additional cash on a certain date or on demand.  These  commitments may have the
effect of requiring  the Fund to increase its  investment in a company at a time
when the Fund might not otherwise  decide to do so (including at a time when the
company's  financial  condition  makes it  unlikely  that such  amounts  will be
repaid).The Fund will always have cash,  short-term money market  instruments or
debt  securities  sufficient to cover any  commitments or to limit any potential
risk.
    

The Fund's ability to receive payments of principal,  interest and other amounts
due in connection with these  investments will depend primarily on the financial
condition of the borrower.  In selecting the loans and other direct  investments
which the Fund will  purchase,  the Adviser  will rely upon its (and not that of
the original lending  institution's) own credit analysis of the borrower. As the
Fund may be required to rely upon  another  lending  institution  to collect and
pass on to the Fund amounts  payable with respect to the loan and to enforce the
Fund's rights under the loan, an insolvency, bankruptcy or reorganization of the
lending  institution  may delay or prevent the Fund from receiving such amounts.
The highly  leveraged  nature of many such loans may make such loans  especially
vulnerable to adverse changes in economic or market  conditions.  Investments in
such loans may involve  additional risks to the Fund. For example,  if a loan is
foreclosed,  the Fund could become part owner of any collateral,  and would bear
the  costs  and  liabilities   associated  with  owning  and  disposing  of  the
collateral. In addition, it is conceivable that under emerging legal theories of
lender  liability,  the Fund could be held liable as a co-lender.  It is unclear
whether  loans  and other  forms of direct  indebtedness  offer  securities  law
protections  against fraud and  misrepresentation.  In the absence of definitive
regulatory guidance,  the Fund relies on the Adviser's research in an attempt to
avoid  situations  where fraud or  misrepresentation  could adversely affect the
Fund. In addition,  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.  To the extent that the Adviser
determines that any such investments are illiquid, the Fund will include them in
the investment limitations described below.

   
"WHEN-ISSUED"  SECURITIES:  When the Fund  commits to  purchase a security  on a
"when-issued" or "forward delivery" basis, it will set up procedures  consistent
with policies  promulgated by the Securities and Exchange Commission (the "SEC")
concerning such purchases. Since that policy currently recommends that an amount
of the  Fund's  assets  equal to the  amount of the  purchase  be held  aside or
segregated to be used to pay for the commitment, the Fund will always have cash,
short-term money market  instruments or debt securities  sufficient to cover any
commitments or to limit any potential risk. However,  although the Fund does not
intend to make such purchases for speculative  purposes and intends to adhere to
policies  promulgated  by the SEC,  purchases  of  securities  on such bases may
involve more risk than other types of purchases.  For example, the Fund may have
to sell assets which have been set aside in order to meet redemptions.  Also, if
the Fund determines it necessary to sell the "when-issued" or "forward delivery"
securities before delivery,  it may incur a loss because of market  fluctuations
since the time the commitment to purchase such securities was made.

FOREIGN  SECURITIES:  The Fund may invest up to 50% (and  expects  generally  to
invest between 5% and 20%) of its total assets in foreign  securities  which are
not traded on a U.S. exchange (not including American  Depositary  Receipts) and
has  authority to invest up to 25% of its total assets in  securities  issued or
guaranteed by foreign  governments or their agencies or  instrumentalities.  The
Fund has made commitments to regulatory  authorities to limit its investments in
securities of any single foreign government issuer to 5% of its total assets and
to continue to maintain its status as a diversified company under the Investment
Company  Act  of  1940,  as  amended  (the  "1940  Act").  As  discussed  in the
Prospectus,  investing  in foreign  securities  generally  represents  a greater
degree of risk than investing in domestic  securities,  due to possible exchange
rate fluctuations,  less publicly available information,  more volatile markets,
less securities regulation, less favorable tax provisions, war or expropriation.
As a result of its  investments  in  foreign  securities,  the Fund may  receive
interest or dividend payments, or the proceeds of the sale or redemption of such
securities,  in the foreign currencies in which such securities are denominated.
Under  certain  circumstances,  such as  where  the  Adviser  believes  that the
applicable  exchange rate is unfavorable at the time the currencies are received
or the Adviser  anticipates,  for any other reason,  that the exchange rate will
improve,  the Fund may hold such  currencies  for an indefinite  period of time.
While the  holding  of  currencies  will  permit the Fund to take  advantage  of
favorable  movements in the applicable exchange rate, such strategy also exposes
the Fund to risk of loss if exchange  rates move in a  direction  adverse to the
Fund's  position.  Such losses  could  reduce any profits or increase any losses
sustained by the Fund from the sale or redemption of securities and could reduce
the dollar value of interest or dividend  payments  received.  The Fund may also
hold foreign currency in anticipation of purchasing foreign securities.
    

AMERICAN  DEPOSITARY   RECEIPTS:   American  Depositary  Receipts  ("ADRs")  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.  ADRs may be sponsored or unsponsored. A sponsored
ADR is  issued by a  depository  which has an  exclusive  relationship  with the
issuer  of the  underlying  security.  An  unsponsored  ADR may be issued by any
number of U.S. depositories. The Fund may invest in either type of ADR. Although
the U.S.  investor  holds a substitute  receipt of ownership  rather than direct
stock certificates,  the use of the depository receipts in the United States can
reduce  costs  and  delays  as well as  potential  currency  exchange  and other
difficulties.  The Fund may  purchase  securities  in local  markets  and direct
delivery of these ordinary  shares to the local  depository of an ADR agent bank
in the foreign  country.  Simultaneously,  the ADR agents  create a  certificate
which  settles at the Fund's  custodian in five days.  The Fund may also execute
trades on the U.S. markets using existing ADRs. A foreign issuer of the security
underlying an ADR is generally not subject to the same reporting requirements in
the United States as a domestic issuer. Accordingly the information available to
a U.S.  investor  will be  limited  to the  information  the  foreign  issuer is
required to  disclose in its own country and the market  value of an ADR may not
reflect undisclosed material information concerning the issuer of the underlying
security.  ADRs may also be subject  to  exchange  rate risks if the  underlying
foreign securities are denominated in foreign currency.

   
MORTGAGE PASS-THROUGH  SECURITIES.  The Fund may invest in mortgage pass-through
securities   as   described   in  the   Prospectus.   Interests   in   pools  of
mortgage-related  securities  differ from other forms of debt securities,  which
normally  provide  for  periodic  payment  of  interest  in fixed  amounts  with
principal  payments  at  maturity  or  specified  call  dates.  Instead,   these
securities  provide  a monthly  payment  which  consists  of both  interest  and
principal  payments.  In effect,  these  payments  are a  "pass-through"  of the
monthly  payments made by the individual  borrowers on their mortgage loans, net
of any fees  paid to the  issuer or  guarantor  of such  securities.  Additional
payments  are  caused  by  prepayments  of  principal  resulting  from the sale,
refinancing  or foreclosure  of the  underlying  property,  net of fees or costs
which may be incurred. Some mortgage pass-through securities (such as securities
issued by the Government National Mortgage Association  ("GNMA"),  are described
as "modified  pass-through."  These securities entitle the holder to receive all
interests and principal payments owed on the mortgages in the mortgage pool, net
of certain  fees,  at the  scheduled  payment  dates  regardless  of whether the
mortgagor actually makes the payment.
    

The principal governmental guarantor of mortgage pass-through  securities is the
GNMA. GNMA is a wholly-owned U.S.  Government  corporation within the Department
of Housing and Urban Development. GNMA is authorized to guarantee, with the full
faith and credit of the U.S.  Government,  the timely  payment of principal  and
interest on securities issued by institutions  approved by GNMA (such as savings
and loan  institutions,  commercial  banks and  mortgage  bankers) and backed by
pools of Federal  Housing  Administration-insured  or  Veteran's  Administration
("VA")-guaranteed  mortgages.  These  guarantees,  however,  do not apply to the
market value or yield of mortgage pass-through  securities.  GNMA securities are
often  purchased  at a  premium  over  the  maturity  value  of  the  underlying
mortgages. This premium is not guaranteed and will be lost if prepayment occurs.

   
Government-related guarantors (i.e., whose guarantees are not backed by the full
faith and credit of the U.S.  Government)  include the Federal National Mortgage
Association ("FNMA") and the Federal Home Loan Mortgage  Corporation  ("FHLMC").
FNMA  is  a   government-sponsored   corporation   owned   entirely  by  private
stockholders.  It is subject to general  regulation  by the Secretary of Housing
and Urban Development.  FNMA purchases conventional residential mortgages (i.e.,
mortgages not insured or guaranteed by any  governmental  agency) from a list of
approved seller/services which include state and federally-chartered savings and
loan  associations,  mutual savings banks,  commercial banks,  credit unions and
mortgage  bankers.  Pass-through  securities issued by FNMA are guaranteed as to
timely payment by FNMA of principal and interest.

FHLMC was created by Congress in 1970 as a corporate instrumentality of the U.S.
Government for the purpose of increasing the availability of mortgage credit for
residential  housing.  FHLMC issues  Participation  Certificates  ("PCs")  which
represent  interest in conventional  mortgages (i.e.,  not federally  insured or
guaranteed) from FHLMC's national portfolio.  FHLMC guarantees timely payment of
interest and ultimate  collection  of principal  regardless of the status of the
underlying mortgage loans.
    

Commercial  banks,  savings and loan  institutions,  private mortgage  insurance
companies,  mortgage  bankers and other  secondary  market  issuers  also create
pass-through  pools of mortgage loans.  Such issuers may also be the originators
and/or servicers of the underlying mortgage-related securities. Pools created by
such  non-governmental  issuers  generally  offer a higher rate of interest than
government and government-related  pools because there are no direct or indirect
government or agency guarantees of payments in the former pools. However, timely
payment of  interest  and  principal  of  mortgage  loans in these  pools may be
supported  by various  forms of insurance or  guarantees,  including  individual
loan, title, pool and hazard insurance and letters of credit.  The insurance and
guarantees  are  issued  by  governmental  entities,  private  insurers  and the
mortgage  poolers.  There  can be no  assurance  that the  private  insurers  or
guarantors can meet their obligations under the insurance  policies or guarantee
arrangements.   The  Fund  may  also  buy  mortgage-related  securities  without
insurance or guarantees.

COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTICLASS PASS-THROUGH SECURITIES:  The
Fund may invest a portion of its assets in collateralized  mortgage  obligations
or  "CMOs",  which are debt  obligations  collateralized  by  mortgage  loans or
mortgage  pass-through  securities.   Typically,   CMOs  are  collateralized  by
certificates  issued by GNMA, FNMA or FHLMC, but also may be  collateralized  by
whole  loans  or  private  mortgage  pass-through  securities  (such  collateral
collectively  hereinafter  referred to as "Mortgage Assets").  The Fund may also
invest a portion of its assets in multiclass  pass-through  securities which are
equity  interests  in a trust  composed of Mortgage  Assets.  Unless the context
indicates   otherwise,   all  references  herein  to  CMOs  include   multiclass
pass-through  securities.  Payments of principal of and interest on the Mortgage
Assets,  and any  reinvestment  income  thereon,  provide  the funds to pay debt
service  on  the  CMOs  or  make  scheduled   distributions  on  the  multiclass
pass-through securities.  CMOs may be issued by agencies or instrumentalities of
the United  States  government  or by private  originators  of, or investors in,
mortgage  loans,  including  savings  and  loan  associations,  mortgage  banks,
commercial  banks,  investment  banks and special  purpose  subsidiaries  of the
foregoing.  The  issuer of a series of CMOS may  elect to be  treated  as a Real
Estate Mortgage Investment Conduit (a "REMIC").

In a CMO,  a series of bonds or  certificates  are  usually  issued in  multiple
classes with different  maturities.  Each class of CMOs,  often referred to as a
"tranch", is issued at a specific fixed or floating coupon rate and has a stated
maturity or final  distribution  date.  Principal  prepayments  on the  Mortgage
Assets may cause the CMOs to be retired  substantially earlier than their stated
maturities or final distribution dates,  resulting in a loss of all or a part of
the premium if any has been paid.  Interest is paid or accrues on all classes of
the CMOs on a monthly,  quarterly  or  semiannual  basis.  The  principal of and
interest on the Mortgage  Assets may be allocated among the several classes of a
series  of a CMO  in  innumerable  ways.  In a  common  structure,  payments  of
principal,  including  any  principal  prepayments,  on the Mortgage  Assets are
applied to the  classes of the series of a CMO in the order of their  respective
stated maturities or final  distribution  dates, so that no payment of principal
will be made on any  class of CMOs  until all other  classes  having an  earlier
stated maturity or final  distribution date have been paid in full. Certain CMOs
may be stripped  (securities which provide only the principal or interest factor
of the underlying security). See "Stripped Mortgage-Backed Securities" below for
a  discussion  of the risks of  investing in these  stripped  securities  and of
investing  in classes  consisting  primarily  of interest  payments or principal
payments.

The Fund may also invest in parallel  pay CMOs and  Planned  Amortization  Class
CMOs ("PAC  Bonds").  Parallel pay CMOs are  structured  to provide  payments of
principal  on each  payment  date to more  than one  class.  These  simultaneous
payments are taken into account in calculating the stated maturity date or final
distribution  date of each class,  which, as with other CMO structures,  must be
retired by its  stated  maturity  date or final  distribution  date,  but may be
retired earlier.  PAC Bonds generally  require payments of a specified amount of
principal on each payment date. PAC Bonds are always  parallel pay CMOs with the
required  principal payment on such securities having the highest priority after
interest has been paid to all classes.

STRIPPED MORTGAGE-BACKED  SECURITIES: In addition, the Fund may invest a portion
of  its  assets  in  stripped  mortgage-backed  securities  ("SMBS")  which  are
derivative    multiclass    mortgage    securities   issued   by   agencies   or
instrumentalities  of the United States government or by private originators of,
or  investors  in,  mortgage  loans,  including  savings and loan  associations,
mortgage banks, commercial banks and investment banks.

SMBS are usually structured with two classes that receive different  proportions
of the interest and principal  distributions  from a pool of Mortgage  Assets. A
common type of SMBS will have one class  receiving some of the interest and most
of the principal  from the Mortgage  Assets,  while the other class will receive
most of the interest and the  remainder  of the  principal.  In the most extreme
case,  one class will receive all of the  interest  (the  interest-only  or "IO"
Class)  while  the  other  class  will  receive  all  of  the   principal   (the
principal-only  or "PO"  Class).  The yield to  maturity  on an IO is  extremely
sensitive  to the rate of  principal  payments  (including  prepayments)  on the
related  underlying  Mortgage Assets, and a rapid rate of principal payments may
have a material  adverse  effect on such  security's  yield to maturity.  If the
underlying  Mortgage Assets experience  greater than anticipated  prepayments of
principal,  the Fund may fail to fully  recoup its initial  investment  in these
securities.  The market value of the class  consisting  primarily or entirely of
principal  payments  generally is  unusually  volatile in response to changes in
interest rates. Because SMBS were only recently introduced,  established trading
markets for these securities have not yet developed, although the securities are
traded among institutional investors and investment banking firms.

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

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

SWAPS AND RELATED  TRANSACTIONS:  The Fund may enter into  interest  rate swaps,
currency  swaps and other  types of  available  swap  agreements,  such as caps,
collars and floors.

Swap  agreements  may be  individually  negotiated  and  structured  to  include
exposure  to a variety of  different  types of  investments  or market  factors.
Depending on their structure, swap ageements may increase or decrease the Fund's
exposure to long or short-term  interest rates (in the U.S. or abroad),  foreign
currency  values,  mortgage  securities,  corporate  borrowing  rates,  or other
factors such as securities  prices or inflation rates.  Swap agreements can take
many  different  forms  and are known by a  variety  of  names.  The Fund is not
limited to any particular form or variety of swap agreement if MFS determines it
is consistent with the Fund's investment objective and policies.

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

The most  significant  factor in the  performance  of swaps,  caps,  floors  and
collars is the change in the specific  interest  rate,  currency or other factor
that determines the amount of payments to be made under the arrangement.  If MFS
is incorrect in its forecasts of such factors, the investment performance of the
Fund would be less than what it would have been if these  investment  techniques
had not been used. If a swap agreement  calls for payments by the Fund, the Fund
must  be  prepared  to  make  such  payments  when  due.  In  addition,  if  the
counterparty's  creditworthiness declined, the value of the swap agreement would
be likely to  decline,  potentially  resulting  in losses.  If the  counterparty
defaults,  the Fund's risk of loss  consists of the net amount of payments  that
the Fund is contractually entitled to receive. The Fund anticipates that it will
be able to  eliminate  or  reduce  its  exposure  under  these  arrangements  by
assignment or other disposition or by entering into an offsetting agreement with
the same or another counterparty.

OPTIONS:  The Fund may write  covered put and call  options and purchase put and
call options on domestic and foreign fixed income  securities that are traded on
U.S. and foreign securities exchanges and over-the-counter. Call options written
by the Fund give the holder the right to buy the underlying  securities from the
Fund at a fixed exercise price;  put options written by the Fund give the holder
the right to sell the underlying security to the Fund at a fixed exercise price.
A call option  written by the Fund is "covered" if the Fund owns the  underlying
security  covered by the call or has an absolute and immediate  right to acquire
that security  without  additional  cash  consideration  (or for additional cash
consideration  held in a segregated account by its custodian) upon conversion or
exchange  of other  securities  held in its  portfolio.  A call  option  is also
covered if the Fund holds a call on the same security and in the same  principal
amount  as the call  written  where the  exercise  price of the call held (a) is
equal to or less than the  exercise  price of the call written or (b) is greater
than the exercise  price of the call written if the  difference is maintained by
the Fund in cash,  high  quality debt  securities  and  short-term  money market
instruments in a segregated account with its custodian.  A put option written by
the Fund is "covered" if the Fund maintains  cash,  high quality debt securities
and short-term money market instruments with a value equal to the exercise price
in a  segregated  account  with its  custodian,  or else holds a put on the same
security and in the same principal  amount as the put written where the exercise
price of the put held is equal to or greater than the exercise  price of the put
written.  Put and call  options  written by the Fund may also be covered in such
other manner as may be in accordance  with the  requirements  of the exchange on
which, or the counter party with which, the option is traded and applicable laws
and  regulations.  The  writer of an option  may have no  control  over when the
underlying  securities must be sold, in the case of a call option, or purchased,
in the case of a put option,  since with regard to certain  options,  the writer
may be assigned an exercise  notice at any time prior to the  termination of the
obligation.
    

Effecting a closing transaction in the case of a written call option will permit
the Fund to write another call option on the  underlying  security with either a
different exercise price or expiration date or both, or in the case of a written
put option will  permit the Fund to write  another put option to the extent that
the  exercise   price  thereof  is  secured  by  deposited  cash  or  short-term
securities.  Such transactions  permit the Fund to generate  additional  premium
income,  which  will  partially  offset  declines  in  the  value  of  portfolio
securities  or  increases  in the  cost  of  securities  to be  acquired.  Also,
effecting  a closing  transaction  will  permit  the cash or  proceeds  from the
concurrent  sale of any  securities  subject  to the option to be used for other
Fund  investments.  If the Fund desires to sell a particular  security  from its
portfolio  on which it has  written  a call  option,  it will  effect a  closing
transaction prior to, or concurrent with, the sale of the security.

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

An option position may be closed out only where there exists a secondary  market
for an option of the same series. If a secondary market does not exist, it might
not be possible to effect closing  transactions  in particular  options with the
result that the Fund would have to exercise  the options in order to realize any
profit.  If the Fund is unable to effect a  closing  purchase  transaction  in a
secondary market, it will not be able to sell the underlying  security until the
option expires or it delivers the underlying security upon exercise. Reasons for
the absence of a liquid secondary market include the following: (i) there may be
insufficient  trading  interest in certain  options;  (ii)  restrictions  may be
imposed by a national  securities  exchange on opening  transactions  or closing
transactions or both; (iii) trading halts, suspensions or other restrictions may
be imposed with respect to particular classes or series of options or underlying
securities;  (iv)  unusual or  unforeseen  circumstances  may  interrupt  normal
operations  on an  exchange;  (v) the  facilities  of an exchange or the Options
Clearing  Corporation  (the  "OCC") may not at all times be  adequate  to handle
current trading  volume;  or (vi) one or more exchanges  could,  for economic or
other  reasons,  decide or be compelled at some future date to  discontinue  the
trading of options (or a particular class or series of options),  in which event
the  secondary  market on that  exchange (or in that class or series of options)
would cease to exist,  although  outstanding  options on that  exchange that had
been issued by the OCC as a result of trades on that exchange  would continue to
be exercisable in accordance with their terms.

The Fund may write options in connection with buy-and-write  transactions;  that
is, the Fund may purchase a security  and then write a call option  against that
security.  The  exercise  price of the call the Fund  determines  to write  will
depend upon the expected price movement of the underlying security. The exercise
price of a call option may be below ("in-the-money"),  equal to ("at-the-money")
or above  ("out-of-the-money")  the current value of the underlying  security at
the time the  option is  written.  If the call  options  are  exercised  in such
transactions,  the Fund's  maximum  gain will be the premium  received by it for
writing the option,  adjusted upwards or downwards by the difference between the
Fund's purchase price of the security and the exercise price. If the options are
not exercised and the price of the underlying  security declines,  the amount of
such decline will be offset in part, or entirely, by the premium received.

The  writing  of  covered  put  options  is  similar  in  terms  of  risk/return
characteristics  to buy-and-write  transactions.  Put options may be used by the
Fund in the same market  environments  that call options are used in  equivalent
buy-and-write transactions.

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

The Fund may purchase put options to hedge against a decline in the value of its
portfolio.  By using put options in this way, the Fund will reduce any profit it
might  otherwise have realized in the  underlying  security by the amount of the
premium paid for the put option and by transaction costs.

The Fund may purchase  call options to hedge against an increase in the price of
domestic  or foreign  securities  that the Fund  anticipates  purchasing  in the
future.  The premium  paid for the call option plus any  transaction  costs will
reduce the benefit,  if any,  realized by the Fund upon  exercise of the option,
and, unless the price of the underlying security rises sufficiently,  the option
may expire worthless to the Fund.

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

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

FUTURES CONTRACTS:  The Fund may enter into contracts for the future delivery of
domestic or foreign fixed income securities or contracts based on municipal bond
or other  financial  indices  including  any index of domestic or foreign  fixed
income  securities,  as such contracts  become  available for trading  ("Futures
Contracts").  Such transactions may be entered into for hedging purposes and for
non-hedging purposes,  subject to applicable law. A "sale" of a Futures Contract
means a  contractual  obligation  to deliver  the  securities  called for by the
contract at a  specified  price in a fixed  delivery  month or, in the case of a
Futures  Contract  on an  index  of  securities,  to  make  or  receive  a  cash
settlement. A "purchase" of a Futures Contract means a contractual obligation to
acquire the  securities  called for by the  contract  at a specified  price in a
fixed  delivery  month  or,  in the case of a  Futures  Contract  on an index of
securities,  to make or receive a cash settlement.  U.S. Futures  Contracts have
been designed by exchanges which have been  designated as "contract  markets" by
the Commodity  Futures  Trading  Commission  (the "CFTC"),  and must be executed
through a futures commission  merchant,  or brokerage firm, which is a member of
the relevant  contract  market.  Existing  contract  markets include the Chicago
Board of Trade and the International  Monetary Market of the Chicago  Mercantile
Exchange.  Futures  Contracts are traded on these  markets,  and,  through their
clearing  corporations,  the exchanges guarantee performance of the contracts as
between the clearing  members of the exchange.  Futures  Contracts  purchased or
sold by the Fund are also traded on foreign exchanges which are not regulated by
the CFTC.

At the same time a Futures Contract is purchased or sold, the Fund must allocate
cash or securities as a deposit payment ("initial deposit"). The initial deposit
varies  but may be as low as 5% or  less of the  value  of the  contract.  Daily
thereafter,  the Futures  Contract is valued and the Fund may be required to pay
or receive  additional  payment of  "variation  margin"  based on changes in the
value of the contract.

At the time of delivery of securities  pursuant to a Futures  Contract  based on
fixed income securities,  adjustments are made to recognize differences in value
arising from the delivery of securities with a different interest rate from that
specified in the contract.  In some (but not many) cases,  securities called for
by a Futures Contract may not have been issued when the contract was written.

A Futures  Contract  based on an index of  securities,  such as a municipal bond
index Futures Contract, provides for a cash payment equal to the amount, if any,
by which the value of the index at  maturity  is above or below the value of the
index  at  the  time  the  contract  was  entered  into,  times  a  fixed  index
"multiplier".  The index underlying such a Futures Contract is generally a broad
based index of securities  designed to reflect  movements in the relevant market
as a whole. The index assigns weighted values to the securities  included in the
index and its composition is changed periodically.

Although Futures Contracts call for the actual delivery of securities or, in the
case of Futures  Contracts based on an index, the making or acceptance of a cash
settlement at a specified  future time,  the  contractual  obligation is usually
fulfilled  before  such  date by  buying  or  selling,  as the case may be, on a
commodities  exchange,  an identical  Futures Contract calling for settlement in
the same month,  subject to the availability of a liquid secondary  market.  The
Fund incurs brokerage fees when it purchases and sells Futures Contracts.

The purpose of the purchase or sale of a Futures Contract for hedging  purposes,
in the case of a  portfolio  such as that of the Fund which  holds or intends to
acquire  long-term  fixed income  securities,  is to attempt to protect the Fund
from fluctuations in interest rates without actually buying or selling long-term
fixed income  securities.  For  example,  if the Fund owns  long-term  bonds and
interest  rates were  expected to  increase,  the Fund might enter into  Futures
Contracts for the sale of debt securities.  Such a sale would have much the same
effect as selling an equivalent value of the long-term bonds in the portfolio of
the Fund by the Fund.  If  interest  rates did  increase,  the value of the debt
securities  in the  portfolio  would  decline,  but  the  value  of the  Futures
Contracts would increase at approximately the same rate, thereby keeping the net
asset value of the Fund from  declining as much as it otherwise  would have. The
Fund could accomplish  similar results by selling bonds with long maturities and
investing in bonds with short  maturities  when  interest  rates are expected to
increase. However, since the futures market is more liquid than the cash market,
the use of  Futures  Contracts  as an  investment  technique  allows the Fund to
maintain a hedging position without having to sell its portfolio securities.

Similarly,  when  it is  expected  that  interest  rates  may  decline,  Futures
Contracts may be purchased to attempt to hedge against anticipated  purchases of
long-term bonds at higher prices. Since the fluctuations in the value of Futures
Contracts  should be similar  to that of  long-term  bonds,  the Fund could take
advantage  of the  anticipated  rise in the  value of  long-term  bonds  without
actually buying them until the market had stabilized.  At that time, the Futures
Contracts could be liquidated and the Fund could then buy long-term bonds on the
cash  market.  To the extent the Fund enters  into  Futures  Contracts  for this
purpose,  the assets in the  segregated  asset  account  maintained to cover the
Fund's  obligations with respect to such Futures  Contracts will consist of cash
or short-term money market  instruments from its portfolio in an amount equal to
the difference  between the fluctuating  market value of such Futures  Contracts
and the aggregate  value of the initial  deposit and variation  margin  payments
made by the Fund with respect to such Futures Contracts.

The ordinary  spreads  between  prices in the cash and futures  markets,  due to
differences in the nature of those markets,  are subject to distortions.  First,
all  participants  in the  futures  market are  subject to initial  deposit  and
variation margin  requirements.  Rather than meeting additional variation margin
requirements,  investors  may close out  Futures  Contracts  through  offsetting
transactions  which could distort the normal  relationship  between the cash and
futures  markets.  Second,  the  liquidity  of the  futures  market  depends  on
participants entering into offsetting  transactions rather than making or taking
delivery. To the extent participants decide to make or take delivery,  liquidity
in the futures market could be reduced, thus producing  distortion.  Third, from
the point of view of speculators, the margin deposit requirements in the futures
market are less  onerous  than margin  requirements  in the  securities  market.
Therefore,  increased  participation  by  speculators  in the futures market may
cause  temporary  price  distortions.  Due to the  possibility of distortion,  a
correct  forecast of general  interest  rate trends by the Adviser may still not
result in a successful transaction.

In addition, Futures Contracts entail risks. Although the Fund believes that use
of such  contracts will benefit the Fund, if the Adviser's  investment  judgment
about the general  direction of interest rates is incorrect,  the Fund's overall
performance  would be poorer than if it had not entered into any such  contract.
For example,  if the Fund has hedged  against the  possibility of an increase in
interest  rates  which  would  adversely  affect  the price of bonds held in its
portfolio,  and interest rates decrease instead,  the Fund will lose part or all
of the benefit of the increased  value of its bonds which it has hedged  because
it will have offsetting losses in its futures  positions.  In addition,  in such
situations,  if the Fund has  insufficient  cash, it may have to sell bonds from
its portfolio to meet daily variation margin  requirements.  Such sales of bonds
may be, but will not  necessarily  be, at  increased  prices  which  reflect the
rising  market.  The Fund may have to sell  securities  at a time when it may be
disadvantageous  to do so.  The  purchase  and  sale of  Futures  Contracts  for
non-hedging purposes involves greater risk, and could result in losses which are
not offset by gains on other portfolio assets.

OPTIONS ON FUTURES CONTRACTS: The Fund may purchase and write options on Futures
Contracts  ("Options  on  Futures  Contracts")  for  hedging  purposes  and  for
non-hedging purposes subject to applicable laws. An Option on a Futures Contract
provides  the  holder  with the  right to enter  into a "long"  position  in the
underlying  Futures Contract in the case of a call option, or a "short" position
in the  underlying  Futures  Contract  in the case of a put  option,  at a fixed
exercise  price  up to a stated  expiration  date  or,  in the  case of  certain
options,  on such date. Such Options on Futures Contracts will be traded on U.S.
contract  markets  regulated  by the  CFTC  as  well  as on  foreign  exchanges.
Depending  on the  pricing  of the  option  compared  to either the price of the
Futures  Contract  upon  which it is based or the price of the  underlying  debt
securities,  it may or may not be  less  risky  than  ownership  of the  Futures
Contract  or  underlying  debt  securities.  As with  the  purchase  of  Futures
Contracts,  when the Fund is not fully invested it may purchase a call Option on
a Futures  Contract to hedge against a market advance due to declining  interest
rates.

The writing of a call Option on a Futures  Contract  constitutes a partial hedge
against  declining  prices of the securities which are deliverable upon exercise
of the Futures  Contract.  If the futures  price at  expiration of the option is
below the  exercise  price,  the Fund will  retain the full amount of the option
premium,  less related transaction costs, which provides a partial hedge against
any decline that may have occurred in the Fund's portfolio holdings. The writing
of a put  Option on a Futures  Contract  constitutes  a  partial  hedge  against
increasing  prices of the securities  which are deliverable upon exercise of the
Futures  Contract.  If the futures  price at  expiration of the option is higher
than the  exercise  price,  the Fund will  retain the full  amount of the option
premium,  less related transaction costs, which provides a partial hedge against
any increase in the price of securities which the Fund intends to purchase. If a
put or call option the Fund has written is exercised, the Fund will incur a loss
which will be reduced by the amount of the  premium it  receives,  less  related
transaction costs. Depending on the degree of correlation between changes in the
value of its  portfolio  securities  and  changes  in the  value of its  futures
positions,  the Fund's losses from existing Options on Futures  Contracts may to
some  extent be  reduced  or  increased  by  changes  in the value of  portfolio
securities.  The  writer of an Option on a Futures  Contract  is  subject to the
requirement  of initial and variation  margin  payments.  The Fund may cover the
writing of call Options on Futures Contracts through purchases of the underlying
Futures Contract or through ownership of the security or securities  included in
the index underlying the Futures  Contract.  The Fund may also cover the writing
of call  Options on Futures  Contracts  through the  purchase  of such  Options,
provided that the exercise  price of the call  purchased (a) is equal to or less
than the exercise  price of the call written or (b) is greater than the exercise
price of the call written if the  difference  is maintained by the Fund in cash,
high  quality debt  securities  or  short-term  money  market  instruments  in a
segregated account with the Fund's custodian. The Fund will cover the writing of
put  Options  on  Futures  Contracts  through  sales of the  underlying  Futures
Contract  or through  segregation  of cash,  high  quality  debt  securities  or
short-term  money  market  instruments  in an  amount  equal to the value of the
security or index underlying the Futures  Contract.  The Fund may also cover the
writing  of put  Options on  Futures  Contracts  through  the  purchase  of such
Options,  provided  that the exercise  price of the put purchased is equal to or
greater than the exercise  price of the put written.  In addition,  the Fund may
cover  put and  call  Options  on  Futures  Contracts  in  accordance  with  the
requirements  of the exchange on which the option is traded and applicable  laws
and regulations.

The purchase of a put Option on a Futures  Contract is similar in some  respects
to the purchase of protective put options on portfolio securities. The Fund will
purchase  a put  Option on a Futures  Contract  to hedge  the  Fund's  portfolio
against the risk of rising interest rates.

The amount of risk the Fund  assumes  when it  purchases  an Option on a Futures
Contract is the  premium  paid for the option plus  related  transaction  costs,
although in order to realize a profit it may be necessary to exercise the option
and close out the underlying  Futures  Contract.  In addition to the correlation
risks  discussed  above,  the  purchase of an option also  entails the risk that
changes  in the  value  of the  underlying  Futures  Contract  will not be fully
reflected  in the value of the  option  purchased.  The writer of an option or a
futures  contract is subject to all the risks of futures  trading  including the
requirement of initial and variation margin  payments.  The purchase and sale of
Options on Futures Contracts for non-hedging purposes involves greater risk, and
could result in losses which are not offset by gains of other portfolio assets.

FORWARD CONTRACTS:  The Fund may enter into contractual  obligations to purchase
or sell a specific  quantity of a given  foreign  currency for a fixed  exchange
rate at a future date ("Forward Contracts").  Forward Contracts are individually
negotiated and are traded through the "interbank  currency market",  an informal
network  of banks  and  brokerage  firms  which  operates  around  the clock and
throughout the world.  Transactions in the interbank market may be executed only
through financial  institutions acting as market- makers in the interbank market
or through  brokers  executing  purchases and sales  through such  institutions.
Market-makers  in the interbank market generally act as principals in taking the
opposite side of their customers'  positions in Forward Contracts and ordinarily
charge  a  mark-up  or  commission  which  may be  included  in the  cost of the
contract.  In addition,  market-makers  may require  their  customers to deposit
collateral upon entering into a Forward  Contract as security for the customer's
obligation  to make or receive  delivery of currency  and to deposit  additional
collateral if exchange  rates move adversely to the  customer's  position.  Such
deposits may function in a manner similar to the margining of Futures  Contracts
described above.

Prior to the stated maturity date of a Forward  Contract,  it may be possible to
liquidate the transaction by entering into an offsetting  contract.  In order to
do so,  however,  a customer may be required to maintain both  contracts as open
positions  until  maturity and to make or receive a settlement of the difference
owed to or from the market-maker or broker at that time.

Forward  Contracts  may  limit  potential  gain  from a  positive  change in the
relationship  between  the U.S.  dollar and  foreign  currencies.  Unanticipated
changes in currency prices may result in poorer overall performance for the Fund
than if it had not engaged in such contracts.

The Fund has  established  procedures  consistent with Statements by the SEC and
its staff  regarding  the use of  Forward  Contracts  by  registered  investment
companies,  which require the use of segregated  assets or "cover" in connection
with the purchase and sale of such  contracts.  In those  instances in which the
Fund satisfies this requirement through segregation of assets, it will maintain,
in a segregated  account,  cash, cash equivalents or high grade debt securities,
which will be marked to market on a daily basis, in an amount equal to the value
of its commitments  under Forward  Contracts  entered into by the Fund. The Fund
may also  enter  into  Forward  Contracts  for  "Cross-hedging"  as noted in the
Prospectus.

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

Conversely,  where a rise in the dollar value of a currency in which  securities
to be acquired are denominated is projected, thereby increasing the cost of such
securities,  the Fund may purchase  call options  thereon.  The purchase of such
options could offset,  at least partially,  the effects of the adverse movements
in  exchange  rates.  As in the case of other  types of  options,  however,  the
benefit to the Fund deriving from purchases of foreign  currency options will be
reduced by the amount of the premium and related transaction costs. In addition,
where  currency  exchange  rates do not move in the  direction  or to the extent
anticipated,  the Fund could sustain losses on transactions in foreign  currency
options  which  would  require it to forego a portion or all of the  benefits of
advantageous changes in such rates.

The Fund may write options on foreign  currencies  for the same types of hedging
purposes.  For example, where the Fund anticipates a decline in the dollar value
of foreign-denominated securities due to adverse fluctuations in exchange rates,
it  could,  instead  of  purchasing  a put  option,  write a call  option on the
relevant  currency.  If the expected decline occurs, the option will most likely
not be exercised  and the  diminution in value of portfolio  securities  will be
offset by the amount of the premium received, less related transaction costs.

Similarly,  instead of purchasing a call option to hedge against an  anticipated
increase in the dollar cost of securities to be acquired, the Fund could write a
put  option  on the  relevant  currency  which,  if  rates  move  in the  manner
projected,  will expire  unexercised  and allow the Fund to hedge such increased
cost up to the amount of the premium,  less related transaction costs. As in the
case of other  types of  options,  however,  the  writing of a foreign  currency
option will  constitute  only a partial  hedge up to the amount of the  premium,
less  related  transaction  costs,  and  only  if  rates  move  in the  expected
direction.  If this does not occur,  the option  may be  exercised  and the Fund
would be required to  purchase or sell the  underlying  currency at a loss which
may not be offset by the amount of the  premium.  Through the writing of options
on foreign currencies,  the Fund also may be required to forego all or a portion
of the  benefits  which  might  otherwise  have  been  obtained  from  favorable
movements in exchange rates.

Options on foreign  currencies  written or  purchased by the Fund will be traded
over-the-counter or on U.S. or foreign securities exchanges. All options written
on  foreign  currencies  will be  covered.  A call  option  written  on  foreign
currencies  by the Fund is  "covered"  if the Fund owns the  underlying  foreign
currency  covered by the call or has an absolute and immediate  right to acquire
that foreign currency without  additional cash  consideration (or for additional
cash  consideration  held  in  a  segregated  account  by  its  custodian)  upon
conversion or exchange of other foreign  currency held in its portfolio.  A call
option is also covered if the Fund has a call on the same  foreign  currency and
in the same principal amount as the call written where the exercise price of the
call held (a) is equal to or less than the exercise price of the call written or
(b) is greater than the exercise  price of the call written if the difference is
maintained  by the Fund in cash,  short-term  money market  instruments  or high
quality debt securities in a segregated account with its custodian. A put option
written on foreign  currencies  by the Fund is "covered"  if the Fund  maintains
cash, short-term money market instruments or high quality debt securities with a
value equal to the exercise price in a segregated account with its custodian, or
else holds a put on the same foreign  currency and in the same principal  amount
as the put  written  where  the  exercise  price  of the put held is equal to or
greater  than  the  exercise  price  of the  put  written.  Options  on  foreign
currencies  written by the Fund may also be covered in such other  manner as may
be in accordance  with the  requirements  of the exchange on which the option is
traded and applicable laws and regulations.

ADDITIONAL RISKS OF OPTIONS ON SECURITIES, FUTURES CONTRACTS, OPTIONS ON FUTURES
CONTRACTS,  FORWARD  CONTRACTS  AND  OPTIONS  ON  FOREIGN  CURRENCIES:   Various
additional risks exist with respect to the trading of options, Futures Contracts
and Forward Contracts.  For example, the Fund's ability effectively to hedge all
or a portion of its portfolio  through  transactions  in such  instruments  will
depend  on the  degree  to which  price  movements  in the  underlying  index or
instrument  correlate with price movements in the relevant portion of the Fund's
portfolio.  The trading of futures and options  entails the  additional  risk of
imperfect  correlation  between movements in the futures or option price and the
price of the underlying  index or obligation,  while the trading of options also
entails  the risk of  imperfect  correlation  between  securities  used to cover
options  written and the securities  underlying  such options.  The  anticipated
spread between the prices may be distorted because of various factors, which are
set forth under  "Investment  Objective,  Policies and  Restrictions  -- Futures
Contracts" above. When the Fund purchases or sells Futures Contracts based on an
index of securities,  the securities  comprising such index will not be the same
as the portfolio  securities being hedged,  thereby creating a risk that changes
in the value of the index will not  correlate  with changes in the value of such
portfolio securities.

The Fund's ability to engage in options and futures  strategies will also depend
on  the  availability  of  liquid  markets  in  such  instruments.   "Investment
Objective,  Policies and Restrictions -- Options" sets forth certain reasons why
a liquid secondary market may not exist.

The liquidity of a secondary  market in a Futures Contract or option thereon may
be  adversely  affected by "daily  price  fluctuation  limits",  established  by
exchanges,  which  limit the  amount of  fluctuation  in the price of a contract
during a single trading day and prohibit trading beyond such limit. In addition,
the  exchanges  on which  futures and options are traded may impose  limitations
governing  the maximum  number of  positions  on the same side of the market and
involving the same underlying instrument which may be held by a single investor,
whether  acting  alone or in concert  with others  (regardless  of whether  such
contracts are held on the same or different  exchanges or held or written in one
or more accounts or through one or more brokers).

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

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

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

In  addition,  options  on  securities,  Futures  Contracts,  Options on Futures
Contracts,  Forward Contracts and options on foreign currencies may be traded on
foreign  exchanges.  Such  transactions  are subject to the risk of governmental
actions affecting trading in or the prices of foreign  currencies or securities.
The  value of such  positions  also  could be  adversely  affected  by (i) other
complex foreign,  political and economic factors,  (ii) lesser availability than
in the United States of data on which to make trading decisions, (iii) delays in
the Fund's  ability to act upon  economic  events  occuring  in foreign  markets
during non-business hours in the United States, (iv) the imposition of different
exercise and settlement terms and procedures and margin requirements than in the
United States and (v) lesser trading volume.

As a result of its  investments  in  foreign  securities,  the Fund may  receive
interest or dividend payments, or the proceeds of the sale or redemption of such
securities,  in foreign  currencies.  The Fund may also be  required  to receive
delivery of the foreign  currencies  underlying options on foreign currencies or
Forward  Contracts it has entered  into.  This could occur,  for example,  if an
option  written  by the Fund is  exercised  or the Fund is unable to close out a
Forward  Contract it has entered into.  In addition,  the Fund may elect to take
delivery of such  currencies.  Under such  circumstances,  the Fund may promptly
convert the foreign  currencies into dollars at the then current  exchange rate.
Alternatively,  the Fund may hold such  currencies  for an indefinite  period of
time if the Adviser  believes  that the exchange rate at the time of delivery is
unfavorable  or if, for any other  reason,  the  Adviser  anticipates  favorable
movements in such rates.

While the  holding  of  currencies  will  permit the Fund to take  advantage  of
favorable movements in the applicable exchange rate, it also exposes the Fund to
risk of loss if such rates  move in a  direction  adverse to a Fund's  position.
Such losses could also adversely affect the Fund's hedging  strategies.  Certain
tax  requirements  may limit  the  extent to which the Fund will be able to hold
currencies.

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

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

LENDING OF  PORTFOLIO  SECURITIES:  The Fund may seek to increase  its income by
lending  portfolio  securities.  Such loans will  usually be made only to member
firms of the New York Stock Exchange (and subsidiaries thereof) and member banks
of the Federal Reserve System, and would be required to be secured  continuously
by collateral in cash, cash equivalents or U.S. Treasury  securities  maintained
on a  current  basis at an  amount  at least  equal to the  market  value of the
securities  loaned.  The Fund would have the right to call a loan and obtain the
securities  loaned at any time on customary  industry  settlement  notice (which
will not usually  exceed five days).  For the duration of a loan, the Fund would
continue to receive the  equivalent  of the  interest or  dividends  paid by the
issuer on the  securities  loaned and would also receive  compensation  from the
investment of the  collateral.  The Fund would not,  however,  have the right to
vote any  securities  having voting rights during the existence of the loan, but
the Fund would call the loan in  anticipation  of an important  vote to be taken
among holders of the securities or of the giving or withholding of their consent
on a material  matter  affecting  the  investment.  As with other  extensions of
credit  there  are  risks of delay in  recovery  or even  loss of  rights in the
collateral should the borrower of the securities fail financially.  However, the
loans would be made only to firms deemed by the Adviser to be of good  standing,
and when, in the judgment of the Adviser,  the consideration which can be earned
currently from  securities  loans of this type justifies the attendant  risk. If
the Adviser  determines to make securities  loans, it is intended that the value
of the  securities  loaned would not exceed 30% of the value of the Fund's total
assets.

MORTGAGE "DOLLAR ROLL"  TRANSACTIONS:  As described in the Prospectus,  the Fund
may enter into mortgage "dollar roll" transactions.  During the roll period, the
Fund foregoes principal and interest paid on the mortgage-backed securities. The
Fund is compensated for the lost interest by the difference  between the current
sales price and the lower price for the future  purchase  (often  referred to as
the  "drop")  as well as by the  interest  earned  on the cash  proceeds  of the
initial sale. The Fund may also be compensated by receipt of a commitment fee.

CORPORATE  ASSET-BACKED  SECURITIES:  The Fund may  invest in  corporate  asset-
backed  securities.  These  securities,  issued by trusts  and  special  purpose
corporations, are backed by a pool of assets, such as credit card and automobile
loan receivables, representing the obligations of a number of different parties.

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.  Credit card  receivables are
generally  unsecured and the debtors are entitled to the  protection of a number
of state and federal  consumer  credit laws, many of which give such debtors the
right to set off certain amounts owed on the credit cards,  thereby reducing the
balance due.  Most issuers of  automobile  receivables  permit the  servicers to
retain  possession of the underlying  obligations.  If the servicer were to sell
these  obligations  to another party,  there is a risk that the purchaser  would
acquire an interest  superior  to that of the holders of the related  automobile
receivables.  In addition, because of the large number of vehicles involved in a
typical  issuance and technical  requirements  under state laws, the trustee for
the  holders  of the  automobile  receivables  may not  have a  proper  security
interest in all of the obligations backing such receivables. Therefore, there is
the  possibility  that  recoveries on  repossessed  collateral  may not, in some
cases, be available to support payments on these securities.

Corporate  asset-backed  securities  are  often  backed  by  a  pool  of  assets
representing  the  obligations of a number of different  parties.  To lessen the
effect of  failures  by obligors to make  payments  on  underlying  assets,  the
securities  may  contain   elements  of  credit  support  which  fall  into  two
categories:   (i)  liquidity  protection  and  (ii)  protection  against  losses
resulting  from  ultimate  default  by an  obligor  on  the  underlying  assets.
Liquidity  protection  refers to the  provision  of  advances,  generally by the
entity  administering the pool of assets, to ensure that the receipt of payments
on the underlying  pool occurs in a timely  fashion.  Protection  against losses
resulting from ultimate  default ensures payment through  insurance  policies or
letters of credit obtained by the issuer or sponsor from third parties. The Fund
will not pay any additional or separate fees for credit  support.  The degree of
credit  support  provided  for each  issue  is  generally  based  on  historical
information  respecting the level of credit risk  associated with the underlying
assets.  Delinquency  or loss in excess of that  anticipated  or  failure of the
credit  support  could  adversely  affect the return on an  instrument in such a
security.

PORTFOLIO TRADING: The portfolio of the Fund will be fully managed by buying and
selling securities,  as well as by holding selected securities to maturity.  The
Fund will seek to maximize the return on its  portfolio  by taking  advantage of
market developments, yield disparities and variations in the creditworthiness of
issuers.  The portfolio  management of the Fund may include use of the following
strategies:

    (1)  varying  the  maturity  mix or  quality  profile  of its  portfolio  as
  warranted by overall market expectations;

    (2) selling one type of debt security  (e.g.,  industrial  bonds) and buying
  another (e.g.,  utility bonds) when disparities arise in their relative values
  and prospects;

    (3) changing  from one debt  security to a similar debt  security when their
  respective yields are distorted due to market factors; and

    (4) changing from one debt  security to a similar debt  security  based upon
  credit analysis and fundamental research.

These  strategies  may result in increases or decreases in the current income of
the Fund available for  distribution to its  shareholders and in its holdings of
debt securities which sell at moderate to substantial premiums or discounts from
face  value.  If the Fund's  expectations  of changes in  interest  rates or its
evaluation of the normal yield relationship  between two securities proves to be
incorrect, the income, net asset value and potential capital gain may be reduced
or its potential capital loss may be increased.

The Fund  will engage in portfolio trading if it believes a transaction net of
costs (including custodian charges) will help in attaining its investment
objective. See "Portfolio Transactions and Brokerage Commissions."

To be eligible to be taxed under the  provisions  of the  Internal  Revenue Code
applicable to regulated investment companies, the Fund must, among other things,
limit its  short-term  trading  so that  less  than 30% of its  gross  income is
derived from gains realized on the sale or other  disposition of securities held
for less than three months. For this purpose, gross income includes all dividend
and interest income and gross realized capital gains,  both short and long-term,
without offset for realized capital losses.

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

INVESTMENT  RESTRICTIONS.  The Fund has adopted the following restrictions which
cannot be changed  without  the  approval  of the  holders of a majority  of its
shares (which,  as used in this Statement of Additional  Information,  means the
lesser of (i) more than 50% of the outstanding  shares of the Trust (or a series
or class, as applicable),  or (ii) 67% or more of the outstanding  shares of the
Trust (or a series or class,  as applicable)  present at a meeting if holders of
more than 50% of the  outstanding  shares of the Trust (or a series or class, as
applicable) are represented in person or by proxy).

The Fund  may not:

    (1) Borrow amounts in excess of 10% of its gross assets,  and then only as a
  temporary measure for extraordinary or emergency purposes, or pledge, mortgage
  or hypothecate  its assets taken at market value to an extent greater than 15%
  of its gross  assets,  in each case taken at the lower of cost or market value
  and  subject to a 300% asset  coverage  requirement  (for the  purpose of this
  restriction,  collateral  arrangements with respect to options on fixed income
  securities, Futures Contracts, Options on Futures Contracts, Forward Contracts
  and options on foreign currencies and payments of initial and variation margin
  in connection therewith are not considered a pledge of assets).

    (2) Underwrite securities issued by other persons except insofar as the Fund
  may  technically be deemed an underwriter  under the Securities Act of 1933 in
  selling a portfolio security.

    (3)  Invest  more  than 25% of the  market  value  of its  total  assets  in
  securities of issuers in any one industry, except that up to 40% of the Fund's
  total assets,  taken at market value,  may be invested in each of the electric
  utility and telephone industries.

    (4) Purchase or sell real estate (including  limited  partnership  interests
  but  excluding  securities  secured  by real  estate  or  interests  therein),
  interests in oil, gas or mineral  leases,  commodities or commodity  contracts
  (except Futures Contracts, Options on Futures Contracts, Forward Contracts and
  options on foreign  currencies) in the ordinary  course of the business of the
  Fund.  The Fund reserves the freedom of action to hold and to sell real estate
  acquired as a result of the ownership of securities.

    (5) Make loans to other persons  except through the lending of its portfolio
  securities in accordance  with, and to the extent permitted by, its investment
  objective and policies and except through repurchase agreements. Not more than
  10% of the Fund's assets will be invested in repurchase agreements maturing in
  more than seven days. For these  purposes the purchase of commercial  paper or
  of all or a portion of a private or public issue of debt securities  shall not
  be considered the making of a loan.

    (6)  Purchase the  securities  of any issuer if such  purchase,  at the time
  thereof,  would  cause  more than 5% of the total  assets of the Fund taken at
  market  value to be  invested in the  securities  of such  issuer,  other than
  securities  issued or  guaranteed  by the U.S.  Government  or its agencies or
  instrumentalities,  and provided further that up to 25% of the total assets of
  the Fund may be invested in  securities  issued or  guaranteed  by any foreign
  government, its agencies or instrumentalities.

    (7) Purchase voting  securities of any issuer if such purchase,  at the time
  thereof,  would cause more than 10% of the  outstanding  voting  securities of
  such issuer to be held by the Fund;  or purchase  securities  of any issuer if
  such  purchase at the time  thereof  would cause more than 10% of any class of
  securities  of such  issuer  to be held by the  Fund.  For  this  purpose  all
  indebtedness  of an issuer  shall be deemed a single  class and all  preferred
  stock of an issuer shall be deemed a single class.

    (8) Invest for the purpose of exercising control or management.

    (9) Purchase  securities issued by any registered  investment company except
  by purchase in the open market where no  commission  or profit to a sponsor or
  dealer  results  from  such  purchase   other  than  the  customary   broker's
  commission,  or except when such purchase, though not made in the open market,
  is part of a plan of merger or consolidation; provided, however, that the Fund
  shall not purchase the  securities of any registered  investment  companies if
  such  purchase  at the time  thereof  would  cause more than 10% of the Fund's
  total assets,  taken at market value, to be invested in the securities of such
  issuers;  and provided,  further,  that the Fund shall not purchase securities
  issued by any open-end investment company.

    (10)  Invest  more  than 5% of its  assets  in  companies  which,  including
  predecessors, have a record of less than three years' continuous operation.

    (11) Purchase or retain in its portfolio any securities  issued by an issuer
  any of whose officers,  directors,  trustees or security holders is an officer
  or Trustee of the Fund, or is a partner,  officer,  director or trustee of the
  investment  adviser of the Fund,  if after the purchase of the  securities  of
  such issuer by the Fund one or more of such  persons  owns  beneficially  more
  than 1/2 of 1% of the  shares  or  securities,  or both,  all  taken at market
  value,  of such issuer,  and such  persons  owning more than 1/2 of 1% of such
  shares or securities  together own beneficially more than 5% of such shares or
  securities, or both, all taken at market value.

    (12)  Purchase any  securities  or  evidences of interest  therein on margin
  except to make deposits on margin in  connection  with options on fixed income
  securities, Futures Contracts, Options on Futures Contracts, Forward Contracts
  and options on foreign  currencies,  and, except that the Fund may obtain such
  short-term credit as may be necessary for the clearance of purchases and sales
  of  securities  and  provided  that  this  shall  not  prevent  the  purchase,
  ownership, holding or sale of contracts for the future acquisition or delivery
  of fixed income securities.

    (13) Sell any  security  which the Fund does not own unless by virtue of its
  ownership  of other  securities  it has at the time of sale a right to  obtain
  securities  without  payment of further  consideration  equivalent in kind and
  amount to the  securities  sold and provided that if such right is conditional
  the sale is made upon the same conditions.

    (14)  Purchase or sell any put or call options or any  combination  thereof,
  provided that this shall not prevent the purchase,  ownership, holding or sale
  of warrants  where the grantor of the warrants is the issuer of the underlying
  securities  or  the  writing,   purchasing  and  selling  of  puts,  calls  or
  combinations thereof with respect to securities, Futures Contracts and foreign
  currencies.

  As a matter of  non-fundamental  policy, the Fund may not invest in securities
(other than repurchase  agreements) which are restricted as to disposition under
the federal  securities  laws (unless the Board of Trustees has determined  that
such  securities  are  liquid  based  upon  trading  markets  for  the  specific
security),  if more than 15% of the  Fund's  assets  would be  invested  in such
securities.

These  investment  restrictions  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.

- ----------
*"Interested persons" (as defined in the 1940 Act) of the Adviser, whose address
 is 500 Boylston Street, Boston, Massachusetts 02116.

Each Trustee and officer holds comparable  positions with certain MFS affiliates
or with  certain  other funds of which MFS or a wholly owned  subsidiary  is the
investment  adviser or distributor.  Mr. Brodkin,  the Chairman of MFD,  Messrs.
Shames and Scott,  Directors of MFD and Mr.  Cavan,  the  Secretary of MFD, hold
similar positions with certain other MFS affiliates. Mr. Bailey is a Director of
Sun Life Assurance  Company of Canada (U.S.) ("Sun Life of Canada (U.S.)"),  the
corporate parent of MFS.

The Fund pays the compensation of non-interested Trustees (who currently receive
a fee of $2,500 per year plus $235 per meeting and  committee  meeting  attended
together with such Trustees' out-of-pocket expenses) and the Trust has adopted a
retirement plan for non-interested  Trustees and Mr. Bailey.  Under this plan, a
Trustee  will retire upon  reaching  age 73 and if the Trustee has  completed at
least 5 years of service,  he would be entitled  to annual  payments  during his
lifetime of up to 50% of such Trustee's  average annual  compensation  (based on
the three years prior to his retirement)  depending on his length of service.  A
Trustee may also retire prior to age 73 and receive  reduced  payments if he has
completed  at least 5 years of  service.  Under  the  plan,  a  Trustee  (or his
beneficiaries)  will also receive benefits for a period of time in the event the
Trustee is disabled or dies.  These benefits will also be based on the Trustee's
average annual  compensation and length of service.  There is no retirement plan
provided by the Trust for the interested Trustees (except Mr. Bailey).  The Fund
will accrue its  allocable  share of  compensation  expenses  each year to cover
current year's service and amortize past service cost.

Set  forth in  Appendix  A hereto is  certain  information  concerning  the cash
compensation  paid to  non-interested  Trustees  and  Mr.  Bailey  and  benefits
accrued, and estimated benefits payable, under the retirement plan.

As of May 1, 1995,  all  Trustees  and officers as a group owned less than 1% of
shares  outstanding on that date. As of May 1, 1995,  Nationwide  Life Insurance
Company,  P.O. Box 182029,  Columbus,  OH, was the record owner of approximately
6.35% of the  outstanding  shares of Class A shares  of the  Fund.  As of May 1,
1995, Merrill Lynch, Pierce, Fenner & Smith, Inc., P.O. Box 45286, Jacksonville,
FL, was the  record  owner of  approximately  5.61% of the  outstanding  Class B
shares of the  Fund.  As of May 1,  1995,  Firstar  Trust  Co.,  P.O.  Box 2973,
Milwaukee,  WI was the record owner of  approximately  13.07% of the outstanding
Class C shares of the Fund. As of May 1, 1995, Merrill Lynch,  Pierce,  Fenner &
Smith, P.O. Box 45286,  Jacksonville,  FL, was the record owner of approximately
11.75% of the outstanding Class C shares of the Fund.

The Declaration of Trust provides that the Trust will indemnify its Trustees and
officers against liabilities and expenses incurred in connection with litigation
in which they may be involved  because of their offices with the Trust,  unless,
as to liabilities to the Trust or its  shareholders,  it is finally  adjudicated
that they  engaged  in  willful  misfeasance,  bad faith,  gross  negligence  or
reckless  disregard of the duties involved in their offices,  or with respect to
any matter,  unless it is adjudicated that they did not act in good faith in the
reasonable  belief that their actions were in the best interest of the Trust. In
the case of settlement,  such indemnification will not be provided unless it has
been  determined  pursuant  to the  Declaration  of Trust that such  officers or
Trustees have not engaged in willful misfeasance, bad faith, gross negligence or
reckless disregard of their duties.

INVESTMENT ADVISER
MFS and its predecessor  organizations have a history of money management dating
from 1924. MFS is a wholly owned subsidiary of Sun Life of Canada (U.S.),  which
in turn is a wholly owned  subsidiary  of Sun Life  Assurance  Company of Canada
("Sun Life").

The Adviser manages the Fund pursuant to an Investment Advisory Agreement, dated
May 20, 1987 (the  "Advisory  Agreement").  The Adviser  provides  the Fund with
overall  investment  advisory and  administrative  services,  as well as general
office facilities.  Subject to such policies as the Trustees may determine,  the
Adviser makes investment decisions for the Fund.
    

For these services and  facilities,  under the Advisory  Agreement,  the Adviser
receives a management  fee computed and paid monthly,  on the basis of a formula
based  upon a  percentage  of the  average  daily net  assets of the Fund plus a
percentage of the gross income  (i.e.,  income other than gains from the sale of
securities)  of  the  Fund,  in  each  case  on  an  annualized  basis  for  the
then-current  fiscal year. The applicable  percentages are reduced as assets and
income reach the following levels:



ANNUAL RATE OF MANAGEMENT FEE         ANNUAL RATE OF MANAGEMENT FEE
BASED ON AVERAGE DAILY NET ASSETS     BASED ON GROSS INCOME
- -----------------------------------   -------------------------------
0.220% of the first $200 million      3.00% of the first $22 million
0.187% of average daily net assets    2.55% of gross income in excess
  in excess of $200 million             of $22 million

   
For the fiscal  years  ended  January  31,  1993,  1994 and 1995,  MFS  received
management  fees under the Advisory  Agreement  of  $2,854,750,  $3,284,878  and
$3,756,072, respectively.

In order to comply  with the expense  limitations  of certain  state  securities
commissions,  the Adviser will reduce its management fee or otherwise  reimburse
the  Fund  for  any  expense,   exclusive  of  interest,   taxes  and  brokerage
commissions, incurred by the Fund in any fiscal year to the extent such expenses
exceed the most restrictive of such state expense limitations.  The Adviser will
make appropriate adjustments to such reimbursements in response to any amendment
or recission of the various state  requirements.  Any such adjustment  would not
become  effective  until the beginning of the Fund's next fiscal year  following
the date of such  amendments  or the date on which such  requirements  become no
longer applicable.

The Fund pays all of its  expenses  (other  than  those  assumed  by MFS or MFD)
including:  Trustee fees (discussed above); governmental fees; interest charges;
taxes;  membership  dues in the Investment  Company  Institute  allocable to the
Fund; fees and expenses of independent  auditors,  of legal counsel,  and of any
transfer agent, registrar and dividend disbursing agent of the Fund; expenses of
repurchasing and redeeming shares;  expenses of preparing,  printing and mailing
share certificates,  shareholder reports,  notices, proxy statements and reports
to governmental officers and commissions; brokerage and other expenses connected
with the execution, recording and settlement of portfolio security transactions;
insurance premiums; fees and expenses of the Fund's custodian,  for all services
to the Fund,  including  safekeeping  of funds and  securities  and  maintaining
required  books and  accounts;  expenses of  calculating  the net asset value of
shares of the Fund; and expenses of shareholder  meetings.  Expenses relating to
the  issuance,  registration  and  qualification  of  shares of the Fund and the
preparation, printing and mailing of prospectuses for such purposes are borne by
the  Fund  except  that  its   Distribution   Agreement  with  MFD,  the  Fund's
Distributor,  requires MFD to pay for prospectuses that are to be used for sales
purposes.  Expenses of the Trust which are not attributable to a specific series
are allocated  among the series in a manner  believed by management of the Trust
to be fair and  equitable.  For a list of the  Fund's  expenses,  including  the
compensation paid to the Trustees who are not officers of MFS, during the fiscal
year ended January 31, 1995,  see "Statement of Operations" in the Fund's Annual
Report  to  shareholders  incorporated  by  reference  into  this  Statement  of
Additional Information.
    

MFS pays the  compensation of the Trust's  officers and of any Trustee who is an
officer of MFS.  The Adviser  also  furnishes  at its own expense all  necessary
administrative services, including office space, equipment,  clerical personnel,
investment  advisory  facilities,  and all executive and  supervisory  personnel
necessary  for managing the  investments  of the Fund,  effecting  the portfolio
transactions  of the Fund,  and,  in general,  administering  the affairs of the
Fund.

   
The  Advisory  Agreement  will  remain in effect  until  August 1, 1995 and will
continue in effect thereafter only if such continuance is specifically  approved
at least  annually  by the Board of  Trustees  or by vote of a  majority  of the
Fund's outstanding shares (as defined under "Investment  Restrictions")  and, in
either  case,  by a majority of the Trustees who are not parties to the Advisory
Agreement  or  interested  persons of any such  party.  The  Advisory  Agreement
terminates automatically if it is assigned and may be terminated without penalty
by vote of a  majority  of the  shares of the Fund (as  defined  in  "Investment
Restrictions") or by either party to the Agreement on not more than 60 days' nor
less than 30 days' written notice.  If MFS ceases to serve as the Adviser to the
Fund, the Fund will change its name so as to delete the term "MFS". The Advisory
Agreement provides that the Adviser may render services to others and may permit
clients  in  addition  to the Fund to use the term  "MFS"  in their  names.  The
Advisory  Agreement  further provides that neither the Adviser nor its personnel
shall be liable  for any error of  judgment  or  mistake  of law or for any loss
arising out of any  investment  or for any act or omission in the  execution and
management  of the Fund,  except  for  willful  misfeasance,  bad faith or gross
negligence  in the  performance  of its or their duties or by reason of reckless
disregard of its or their obligations and duties under the Advisory Agreement.
    

CUSTODIAN
State Street Bank and Trust  Company (the  "Custodian")  is the custodian of the
Fund's  assets.  The  Custodian's   responsibilities   include  safekeeping  and
controlling the Fund's cash and securities, handling the receipt and delivery of
securities,  determining  income and  collecting  interest and  dividends on the
Fund's  investments,  maintaining books of original entry for portfolio and fund
accounting and other required books and accounts,  and calculating the daily net
asset  value  of each  class of  shares  of the  Fund.  The  Custodian  does not
determine the  investment  policies of the Fund or decide which  securities  the
Fund  will buy or sell.  The Fund may,  however,  invest  in  securities  of the
Custodian   and  may  deal  with  the   Custodian  as  principal  in  securities
transactions.  The Trustees have reviewed and approved as in the best  interests
of the Fund and its  shareholders  the  custodial  arrangements  with The  Chase
Manhattan  Bank, N.A. for securities of the Fund held outside the United States.
The  Custodian  also acts as the  dividend  disbursing  agent for the Fund.  The
Custodian  has  contracted  with the Adviser for the Adviser to perform  certain
accounting  functions  related to  options  transactions  for which the  Adviser
receives remuneration on a cost basis.

   
SHAREHOLDER SERVICING AGENT
MFS Service Center,  Inc. (the "Shareholder  Servicing  Agent"),  a wholly owned
subsidiary  of MFS, is the Fund's  shareholder  servicing  agent,  pursuant to a
Shareholder  Servicing Agent  Agreement,  effective  August 1, 1985 (the "Agency
Agreement") with the Trust. The Shareholder  Servicing Agent's  responsibilities
under the Agency Agreement include  administering and performing  transfer agent
functions and the keeping of records in connection  with the issuance,  transfer
and  redemption  of each class of shares of the Fund.  For these  services,  the
Shareholder  Servicing  Agent will receive a fee based on the net assets of each
class of  shares  of the Fund,  computed  and paid  monthly.  In  addition,  the
Shareholder  Servicing Agent will be reimbursed by the Fund for certain expenses
incurred  by the  Shareholder  Servicing  Agent on behalf  of the Fund.  For the
fiscal year ended  January 31,  1995,  the Fund paid the  Shareholder  Servicing
Agent  $1,445,125  under  the  Agency  Agreement.  State  Street  Bank and Trust
Company,  the  dividend  and  distribution  disbursing  agent of the  Fund,  has
contracted  with the  Shareholder  Servicing  Agent to  administer  and  perform
certain dividend and distribution disbursing functions for the Fund.

DISTRIBUTOR
MFD, a wholly owned  subsidiary of MFS, serves as distributor for the continuous
offering  of shares of the Fund  pursuant  to a  Distribution  Agreement,  dated
January 1, 1995 (the  "Distribution  Agreement").  Prior to January 1, 1995, MFS
Financial  Services,  Inc. ("FSI"),  another wholly owned subsidiary of MFS, was
the Fund's distributor.  Where this SAI refers to MFD in relation to the receipt
or  payment of money  with  respect  to a period or periods  prior to January 1,
1995,  such  reference  shall be deemed to include  FSI, as the  predecessor  in
interest to MFD.

CLASS A  SHARES:  MFD  acts as agent in  selling  Class A shares  of the Fund to
dealers.  The public  offering  price of Class A shares of the Fund is their net
asset value next computed  after the sale plus a sales charge which varies based
upon the quantity purchased. The public offering price of a Class A share of the
Fund is  calculated  by  dividing  net  asset  value  of a Class A share  by the
difference (expressed as a decimal) between 100% and the sales charge percentage
of  offering  price   applicable  to  the  purchase  (see   "Purchases"  in  the
Prospectus).  The sales  charge  scale set forth in the  Prospectus  applies  to
purchases of Class A shares of the Fund alone or in  combination  with shares of
all classes of certain  other funds in the MFS Family of Funds (the "MFS Funds")
and other funds (as noted under Right of Accumulation) by any person,  including
members of a family unit (e.g.,  husband, wife and minor children) and bona fide
trustees,  and also applies to purchases made under the Right of Accumulation or
a Letter of Intent (see  "Investment and Withdrawal  Programs" in this Statement
of  Additional  Information).  A group might  qualify to obtain  quantity  sales
charge discounts (see "Investment and Withdrawal Programs" in this SAI).

Class A  shares  of the Fund may be sold at their  net  asset  value to  certain
persons and in certain instances as described in the Prospectus.  Such sales are
made without a sales charge to promote good will with  employees and others with
whom MFS, MFD and/or the Fund have business relationships, and because the sales
effort, if any, involved in making such sales is negligible.

MFD allows  discounts  to dealers  (which  are alike for all  dealers)  from the
applicable  public  offering  price of the  Class A  shares.  Dealer  allowances
expressed as a  percentage  of offering  price for all  offering  prices are set
forth in the  Prospectus  (see  "Purchases" in the  Prospectus).  The difference
between the total  amount  invested  and the sum of (a) the net  proceeds to the
Fund and (b) the dealer  commission is the commission  paid to the  distributor.
Because of rounding in the  computation  of offering  price,  the portion of the
sales charge paid to the  distributor may vary and the total sales charge may be
more or less than the sales charge  calculated  using the sales charge expressed
as a percentage of offering price or as a percentage of the net amount  invested
as listed in the Prospectus. In the case of the maximum sales charge, the dealer
retains 4% and MFS retains approximately 3/4 of 1% of the public offering price.
MFD, on behalf of the Fund,  pays a  commission  to dealers who initiate and are
responsible for purchases of $1 million or more as described in the Prospectus.

CLASS B AND CLASS C  SHARES:  MFD acts as agent in  selling  Class B and Class C
shares of the Fund to dealers.  The public offering price of Class B and Class C
shares is their net asset value next computed after the sale (see "Purchases" in
the Prospectus).

GENERAL:  Neither MFD nor  dealers  are  permitted  to delay  placing  orders to
benefit themselves by a price change. On occasion,  MFD may obtain brokers loans
from  various  banks,  including  the  custodian  banks  for the MFS  Funds,  to
facilitate  the  settlement  of sales of shares of the Fund to dealers.  MFD may
benefit from its temporary holding of funds paid to it by investment dealers for
the purchase of Fund shares.

For the Fund's fiscal year ended January 31, 1995, MFD received sales charges of
$105,333 and dealers  received sales charges of $612,900 (as their concession on
gross sales  charges of $718,233)  for selling  Class A shares of the Fund;  the
Fund  received  $80,688,929  representing  the aggregate net asset value of such
shares.  For the Fund's fiscal year ended January 31, 1994,  MFD received  sales
charges of $160,262  and dealers  received  sales  charges of $946,284 (as their
concession on gross sales charges of  $1,106,546)  for selling Class A shares of
the Fund;  the Fund received  $98,444,425  representing  the aggregate net asset
value of such shares.  For the Fund's  fiscal year ended  January 31, 1993,  MFD
received  sales  charges of  $192,913  and  dealers  received  sales  charges of
$999,549 (as their  concession on gross sales charges of $1,192,462) for selling
Class A shares of the  Fund;  the Fund  received  $93,122,736  representing  the
aggregate net asset value of such shares.

For the  Fund's  fiscal  year  ended  January  31,  1995,  the CDSC  imposed  on
redemption of Class A shares was $303.

For the Fund's fiscal year ended  January 31, 1995 and for the period  September
7, 1993 through  January 31, 1994,  the CDSC  imposed on  redemption  of Class B
shares was $578,443 and $322,272, respectively.

The Distribution  Agreement will remain in effect until August 1, 1996, and will
continue in effect thereafter only if such continuance is specifically  approved
at least  annually  by the Board of  Trustees  or by vote of a  majority  of the
Trust's shares (as defined in "Investment Restrictions") and, in either case, by
a majority of the Trustees who are not parties to the Distribution  Agreement or
interested  persons of any such party.  The  Distribution  Agreement  terminates
automatically if it is assigned and may be terminated  without penalty by either
party on not more than 60 days' nor less than 30 days' notice.
    

4.  PORTFOLIO TRANSACTIONS AND BROKERAGE COMMISSIONS

Specific  decisions  to purchase or sell  securities  for the Fund are made by a
portfolio manager who is an employee of the Adviser.  Changes in the investments
of the Fund are reviewed by the Board of Trustees.  The Fund's portfolio manager
may serve  other  clients of the Adviser or any  subsidiary  of the Adviser in a
similar capacity.

The  primary   consideration  in  placing  portfolio  security  transactions  is
execution at the most favorable  prices.  The Adviser has complete freedom as to
the  markets  in which,  and the  broker-dealers  through  which,  it seeks this
result. Debt securities are traded principally in the over-the-counter market on
a net basis through dealers acting for their own account and not as brokers. The
cost  of  securities  purchased  from  underwriters  includes  an  underwriter's
commission or concession,  and the prices at which  securities are purchased and
sold from and to dealers  include a dealer's  mark-up or mark- down. The Adviser
normally seeks to deal directly with the primary  market makers  unless,  in its
opinion,  better prices are available  elsewhere.  Subject to the requirement of
seeking execution at the best available price,  securities may, as authorized by
the  Advisory  Agreement,  be bought from or sold to dealers who have  furnished
statistical,  research and other  information  or services to the Adviser.  From
time to time  soliciting  dealer  fees may be  available  to the  Adviser on the
tender of the  Fund's  portfolio  securities  in  so-called  tender or  exchange
offers.  Such soliciting dealer fees will be in effect recaptured by the Fund to
the extent possible. At present no other recapture arrangements are in effect.

   
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 as a
factor in the  selection  of  broker-dealers  to execute  the  Fund's  portfolio
transactions.

During the fiscal  years ended  January 31, 1993,  1994 and 1995,  the Fund paid
total brokerage  commissions (which term includes  underwriters'  concessions on
new issues of fixed  income  securities)  of  $41,069.00,  $38,422 and  $14,184,
respectively.
    

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

5.  SHAREHOLDER SERVICES

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

   
  LETTER OF INTENT:  If a shareholder  (other than a group  purchaser  described
below)  anticipates  purchasing  $100,000  or more of Class A shares of the Fund
alone or in combination  with shares of Class B or Class C of the Fund or any of
the  classes of other MFS Funds or MFS Fixed Fund  within a 13-month  period (or
36-month period for purchases of $1 million or more), the shareholder may obtain
Class A shares of the Fund at the same reduced  sales charge as though the total
quantity  were  invested  in one lump sum by  completing  the  Letter  of Intent
section  of the  Account  Application  or  filing a  separate  Letter  of Intent
application  (available from the Shareholder  Servicing Agent) within 90 days of
the  commencement of purchases.  Subject to acceptance by MFD and the conditions
mentioned  below,  each  purchase  will  be  made  at a  public  offering  price
applicable to a single  transaction of the dollar amount specified in the Letter
of Intent  application.  The  shareholder or his dealer must inform MFD that the
Letter of Intent is in effect each time shares are  purchased.  The  shareholder
makes no commitment to purchase  additional  shares, but if his purchases within
13-months (or 36 months in the case of purchases of $1 million or more) plus the
value of shares credited toward  completion of the Letter of Intent do not total
the sum  specified,  he will pay the  increased  amount of the  sales  charge as
described  below.  Instructions  for  issuance of shares in the name of a person
other  than  the  person  signing  the  Letter  of  Intent  application  must be
accompanied by a written  statement from the dealer stating that the shares were
paid for by the person signing such Letter of Intent.  Neither income  dividends
nor capital gain distributions  taken in additional shares will apply toward the
completion  of the Letter of Intent.  Dividends and  distributions  of other MFS
Funds   automatically   reinvested  in  shares  of  the  Fund  pursuant  to  the
Distribution  Investment  Program will also not apply toward  completion  of the
Letter of Intent.
    

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

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

   
  RIGHT  OF  ACCUMULATION:  A  shareholder  qualifies  for  cumulative  quantity
discounts  on the  purchase  of  Class A  shares  when  that  shareholder's  new
investment,  together with the current  offering  price value of all holdings of
all  classes  of shares of that  shareholder  in the MFS Funds or MFS Fixed Fund
reaches a discount  level.  (See  "Purchases"  in the  Prospectus  for the sales
charges on quantity purchases.) For example, if a shareholder owns shares valued
at $75,000 and  purchases an  additional  $25,000 of Class A shares of the Fund,
the sales charge for the $25,000  purchase  would be at the rate of 4% (the rate
applicable to single  transactions of $100,000).  A shareholder must provide the
Shareholder  Servicing  Agent (or his  investment  dealer must provide MFD) with
information to verify that the quantity  sales charge  discount is applicable at
the time the investment is made.
    

  DISTRIBUTION  INVESTMENT  PROGRAM:  Distributions of net investment income and
capital gains made by the Fund with respect to a particular  class of shares may
be  automatically  invested  in shares of the same class of one of the other MFS
Funds,  if shares of the fund are available for sale. Such  investments  will be
subject to additional  purchase minimums.  Distributions will be invested at net
asset value (without a sales charge) and not subject to any CDSC.  Distributions
will  be  invested  at the  close  of  business  on the  payable  date  for  the
distribution.  A shareholder  considering the  Distribution  Investment  Program
should  obtain  and read the  prospectus  of the  other  fund and  consider  the
differences in objectives and policies before making any investment.

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

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

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

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

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

A shareholder's right to make additional investments in any of the MFS Funds, to
make  exchanges  of shares from one MFS Fund to another and to withdraw  from an
MFS  Fund,  as well as a  shareholder's  other  rights  and  privileges  are not
affected by a shareholder's participation in the Automatic Exchange Plan.

The Automatic  Exchange Plan is part of the Exchange  Privilege.  For additional
information  regarding the Automatic  Exchange Plan,  including the treatment of
any CDSC, see "Exchange Privilege" below.

  REINSTATEMENT  PRIVILEGE:  Shareholders  of the Fund and  shareholders  of the
other MFS Funds (except MFS Money Market Fund, MFS Government  Money Market Fund
and  holders  of Class A shares of MFS Cash  Reserve  Fund in the case where the
shares are acquired  through direct  purchase or reinvested  dividends) 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 the fund are
available  for  sale) at net  asset  value  (without  a sales  charge)  and,  if
applicable, with credit for any CDSC paid. In the case of proceeds reinvested in
MFS Money Market Fund,  MFS  Government  Money Market Fund and Class A shares of
MFS Cash Reserve Fund,  the  shareholder  has the right to exchange the acquired
shares  for  shares of  another  MFS Fund at net  asset  value  pursuant  to the
exchange  privilege  described below. Such a reinvestment must be made within 90
days of the redemption and is limited to the amount of the redemption  proceeds.
If the shares  credited with any CDSC paid are then redeemed within six years of
the initial  purchase or within 12-months of the initial purchase in the case of
certain  Class A shares,  such CDSC will be imposed  upon  redemption.  Although
redemptions and repurchases of shares are taxable events, a reinvestment  within
a certain  period of time in the same fund may be  considered  a "wash sale" and
may result in the inability to recognize  currently all or a portion of any loss
realized on the original redemption for federal income tax purposes.  Please see
your tax adviser for further information.

EXCHANGE  PRIVILEGE  -- Subject to the  requirements  set forth below and unless
otherwise noted in the Prospectus of any of the other MFS Funds,  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 at net asset  value (if  shares of the fund
are available for sale). In addition, Class C shares may be exchanged for shares
of MFS Money Market Fund at net asset value.  Exchanges  will be made only after
instructions  in  writing  or  by  telephone  (an  "Exchange  Request")  for  an
established account are received by the Shareholder Servicing Agent.

   
Each Exchange  Request must be in proper form (i.e.,  if in writing -- signed by
the record  owner(s)  exactly as the shares are  registered;  if by telephone --
proper account  identification is given by the dealer or shareholder of record),
and each  exchange must involve  either  shares having an aggregate  value of at
least  $1,000 or all the shares in the 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 the Shareholder  Servicing Agent).  Each
exchange  involves the  redemption of the shares of the Fund to be exchanged and
the purchase at the net asset value (i.e., without a sales charge) of the shares
of the same class of the other MFS Fund.  Any gain or loss on the  redemption of
the shares  exchanged is  reportable  on the  shareholder's  federal  income tax
return,  unless  both the  shares  received  and the shares  surrendered  in the
exchange are held in a tax-deferred retirement plan or other tax-exempt account.
No  more  than  five  exchanges  may be  made in any  one  Exchange  Request  by
telephone.  If the  Exchange  Request is received by the  Shareholder  Servicing
Agent  prior to the close of  regular  trading  on the  Exchange,  the  exchange
usually will occur on that day if all of the  requirements  set forth above have
been complied with at the time.  However,  payment of the redemption proceeds by
the Fund,  and thus purchase of shares of the other MFS Fund, may be delayed for
up to seven days if the Fund  determines  that such a delay would be in the best
interest  of all its  shareholders.  Investment  dealers  which  have  satisfied
criteria  established  by MFD may  also  communicate  a  shareholder's  Exchange
Request to MFD by facsimile subject to the requirements set forth above.
    

No CDSC is  imposed on  exchanges,  although  liability  for the CDSC is carried
forward to the  exchanged  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.  Any gain or loss on the  redemption  of the
shares  exchanged is reportable in the  shareholders  federal income tax return,
unless such shares were held in a tax-deferred retirement plan.

Additional information with respect to any of the MFS Funds, including a copy of
its  current  prospectus,  may  be  obtained  from  investment  dealers  or  the
Shareholder Servicing Agent. A shareholder should obtain and read the prospectus
of the other MFS Fund and consider the  differences  in objectives  and policies
before making any exchange.  Shareholders in the other MFS Funds (except holders
of shares of MFS Money Market Fund, MFS Government Money Market Fund and Class A
shares of MFS Cash Reserve Fund acquired  through direct  purchase and dividends
reinvested  prior to June 1, 1992) have the right to exchange  their  shares for
shares  of the  Fund,  subject  to the  conditions,  if any,  set forth in their
respective prospectuses. In addition, unitholders of the MFS Fixed Fund have the
right to exchange their units (except units acquired  through direct  purchases)
for shares of the Fund,  subject to the  conditions,  if any,  imposed upon such
unitholders by the MFS Fixed Fund.

Any state income tax advantages for investment in shares of each state- specific
series of MFS Municipal Series Trust may only benefit  residents of such states.
Investors  should  consult  with  their own tax  advisers  to be sure this is an
appropriate  investment,  based on their  residency and each state's  income tax
laws.

   
The exchange  privilege  (or any aspect of it) may be changed or discon-  tinued
and is subject to certain limitations (see "Purchases" in the Prospectus).

TAX-DEFERRED  RETIREMENT PLANS -- Except as noted below,  shares of the Fund may
be purchased by all types of tax-deferred  retirement plans. MFD makes available
through investment dealers plans and/or custody agreements for the following:
    

  Individual Retirement Accounts (IRAs) (for individuals and their non- employed
  spouses who desire to make limited contributions to a tax-deferred  retirement
  program  and,  if  eligible,  to receive a federal  income tax  deduction  for
  amounts contributed);

  Simplified Employee Pension (SEP-IRA) Plans;

  Retirement Plans Qualified under Section 401(k) of the Internal Revenue Code
  of 1986, as amended;

  403(b) Plans (deferred compensation arrangements for employees of public
  school systems and certain non-profit organizations); and

  Certain other qualified pension and profit-sharing plans.

   
The plan  documents  and forms  provided by MFD designate a trustee or custodian
(unless  another  trustee or custodian is designated by the  individual or group
establishing the plan) and contain specific  information  about the plans.  Each
plan provides that dividends and distributions will be reinvested automatically.
For further  details  with  respect to any plan,  including  fees charged by the
trustee, custodian or MFD, tax consequences and redemption information,  see the
specific  documents for that plan.  Plan documents  other than those provided by
MFD may be used to  establish  any of the plans  described  above.  Third  party
administrative services,  available for some corporate plans, may limit or delay
the processing of transactions.
    
Investors should consult with their tax advisers before  establishing any of the
tax-deferred retirement plans described above.

Class C shares are not currently  available for purchase by any retirement  plan
qualified under Internal Revenue Code section 401(a) or 403(b) if the retirement
plan and/or the sponsoring  organization subscribe to the MFS FUNDamental 401(k)
Plan or another similar 401(a) or 403(b) recordkeeping program made available by
the Shareholder Servicing Agent.

6.  TAX STATUS

The Fund has  elected  to be  treated  and  intends  to  qualify  each year as a
"regulated  investment  company" under Subchapter M of the Internal Revenue Code
of 1986,  as amended (the "Code"),  by meeting all  applicable  requirements  of
Subchapter  M,  including  requirements  as to the  nature of the  Fund's  gross
income, the amount of Fund distributions, and the composition and holding period
of the Fund's  portfolio  assets.  Because the Fund intends to distribute all of
its net investment  income and net realized capital gains in accordance with the
timing  requirements  imposed by the Code, it is expected that the Fund will not
be required  to pay any  federal  income or excise  taxes,  although  the Fund's
foreign-source  income may be subject to foreign  withholding taxes. If the Fund
should fail to qualify as a "regulated investment company" in any year, the Fund
would incur a regular  corporate  federal income tax upon its taxable income and
Fund distributions would generally be taxable as ordinary dividend income to the
shareholders.  As long as it qualifies as a "regulated investment company" under
the Code,  the Fund will not be required to pay  Massachusetts  income or excise
taxes.

   
Shareholders of the Fund normally will have to pay federal income taxes, and any
state or local  taxes,  on the  dividends  and capital gain  distributions  they
receive from the Fund. Dividends from ordinary income and distributions from net
short-term  capital  gains,  whether paid in cash or  reinvested  in  additional
shares,  are taxable to the Fund's  shareholders  as ordinary income for federal
income tax  purposes.  Because  the Fund's  income  will  consist  primarily  of
interest,  its distributions are not, for the most part, expected to be eligible
for the  dividends-received  deduction  for  corporations.  Availability  of the
deduction for  particular  shareholders  is subject to certain  limitations  and
deducted  amounts  may be subject to the  alternative  minimum  tax or result in
certain  basis  adjustments.  Distributions  from net capital  gains (i.e.,  the
excess of net  long-term  capital  gains over net  short-term  capital  losses),
whether  paid  in  cash  or  invested  in  additional  shares,  are  taxable  to
shareholders as long-term  capital gains for federal income tax purposes without
regard  to the  length  of time  shareholders  have  owned  their  shares.  Fund
dividends declared in October, November or December to shareholders of record in
such a month and paid the following  January will be taxable to  shareholders as
if received on December 31 of the year in which the dividends are declared.  The
Fund will notify its shareholders regarding the tax status of its distributions.
    

Any Fund distribution of net capital gains or net short-term  capital gains will
have the effect of reducing  the per share net asset value of shares in the Fund
by the amount of the distribution. Shareholders purchasing shares shortly before
the  record  date of any such  distribution  may thus pay the full price for the
shares and then  effectively  receive a portion of the purchase  price back as a
taxable distribution.

In general,  any gain or loss realized upon a taxable  disposition  of shares of
the Fund by a  shareholder  that  holds such  shares as a capital  asset will be
treated as long-term  capital gain or loss if the shares have been held for more
than twelve months and otherwise as  short-term  capital gain or loss.  However,
any loss realized upon a redemption of shares in the Fund held for six months or
less  will  be  treated  as a  long-term  capital  loss  to  the  extent  of any
distributions  of net capital gain made with respect to those  shares.  Any loss
realized upon a redemption of shares may also be disallowed under rules relating
to wash sales.  Gain may be increased  (or loss  reduced)  upon a redemption  of
Class A shares of the Fund within ninety days after their  purchase  followed by
any  purchase  (including  purchases  by  exchange or by  reinvestment)  without
payment  of an  additional  sales  charge  of Class A  shares  of the Fund or of
another MFS Fund (or any other shares of an MFS Fund generally sold subject to a
sales charge).

The Fund's  current  dividend and  accounting  policies  will affect the amount,
timing,  and character of  distributions  to shareholders and may, under certain
circumstances,  make an economic return of capital taxable to shareholders.  Any
investment in zero coupon securities,  certain stripped  securities,  securities
calling  for  deferred  interest  or payment of  interest  in-kind  and  certain
securities  purchased  at a market  discount  will  cause the Fund to  recognize
income prior to the receipt of cash payments  with respect to these  securities.
In order to distribute  this income and avoid a tax on the Fund, the Fund may be
required  to  liquidate  portfolio  securities  that  it  might  otherwise  have
continued to hold,  potentially  resulting in additional taxable gain or loss to
the Fund.  Investment  in  residual  interests  of a CMO that has  elected to be
treated as a real estate  mortgage  investment  conduit,  or "REMIC," can create
complex tax problems,  especially if the Fund has state or local  governments or
other tax-exempt organizations as investors.

   
The Fund's transactions in options, Futures Contracts and Forward Contracts will
be subject to special tax rules that may affect the amount, timing and character
of  distributions to shareholders.  For example,  certain  positions held by the
Fund on the last  business  day of each  taxable  year  will be marked to market
(i.e.,  treated as if closed out) on such day,  and any gain or loss  associated
with such positions will be treated as 60% long-term and 40% short-term  capital
gain or loss. Certain positions held by the Fund that substantially diminish its
risk of loss with respect to other  positions in its  portfolio  may  constitute
"straddles,"  which are subject to special tax rules that may cause  deferral of
Fund  losses,  adjustments  in  the  holding  periods  of  Fund  securities  and
conversion of short-term into long-term  capital  losses.  Certain tax elections
exist for straddles which could alter the effects of these rules.  The Fund will
limit its activities in options, Futures Contracts, Forward Contracts, and swaps
and related  transactions  to the extent  necessary to meet the  requirements of
Subchapter M of the Code.
    

Special tax  considerations  apply with  respect to foreign  investments  of the
Fund.  Foreign  exchange gains and losses realized by the Fund will generally be
treated as ordinary  income and losses.  The holding of foreign  currencies  and
investment by the Fund in certain "passive foreign investment  companies" may be
limited in order to avoid imposition of a tax on the Fund.

   
Investment income received by the Fund from sources within foreign countries may
be subject to foreign  income  taxes  withheld at the source;  the Fund does not
expect to be able to pass  through  to  shareholders  foreign  tax  credits  and
deductions  with respect to such foreign  taxes.  The United  States has entered
into tax  treaties  with many foreign  countries  that may entitle the Fund to a
reduced rate of tax or an exemption from tax on such income; the Fund intends to
operate so as to qualify for treaty  reduced  rates where  available.  It is not
possible,  however,  to determine  the Fund's  effective  rate of foreign tax in
advance  since the amount of the Fund's  assets to be  invested  within  various
countries is not known.

Dividends  and  certain  other  payments  to  persons  who are not  citizens  or
residents  of the  United  States  or U.S.  entities  ("Non-U.S.  Persons")  are
generally  subject to U.S. tax  withholding at the rate of 30%. The Fund intends
to withhold  U.S.  federal  income tax at the rate of 30% on any  dividends  and
other  payments made to Non-U.S.  Persons that are subject to such  withholding,
regardless of whether a lower rate may be permitted under an applicable  treaty.
Any amounts  overwithheld may be recovered by such persons by filing a claim for
refund with the U.S. Internal Revenue Service within the time period appropriate
to such claims.  Distributions  received  from the Fund by Non-U.S.  Persons may
also be  subject  to tax under the laws of their own  jurisdiction.  The Fund is
also required in certain  circumstances to apply backup withholding at a rate of
31% on  taxable  dividends  and  redemption  proceeds  paid  to any  shareholder
(including  a  Non-U.S.  Person)  who  does  not  furnish  to the  Fund  certain
information  and   certifications   or  who  is  otherwise   subject  to  backup
withholding.  However,  backup withholding will not be applied to payments which
have been subject to 30% withholding.

Fund  distributions  that are derived from interest on  obligations  of the U.S.
Government and certain of its agencies and instrumentalities  (but generally not
from capital gains  realized upon the  disposition of such  obligations)  may be
exempt from state and local taxes.  The Fund intends to advise  shareholders  of
the portion of its dividends  which consist of such interest.  Shareholders  are
urged to consult  their tax advisers  regarding  the possible  exclusion of such
portion of their dividends for state and local income tax purposes.
    

7.  DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES

   
The  Declaration  of Trust permits the Trustees to issue an unlimited  number of
full and fractional Shares of Beneficial  Interest (without par value) of one or
more  series and to divide or combine the shares of any series into a greater or
lesser number of shares without thereby  changing the  proportionate  beneficial
interests in that series.  The Trustees have currently  authorized shares of the
Fund and one other  series.  The  Declaration  of Trust further  authorizes  the
Trustees  to  classify  or  reclassify  any  series of  shares  into one or more
classes.  Pursuant  thereto,  the Trustees have authorized the issuance of three
classes of shares of the Fund,  Class A, Class B and Class C shares.  Each share
of a class of the Fund represents an equal proportionate  interest in the assets
of the Fund allocable to that class. Upon liquidation of the Fund,  shareholders
of each  class  are  entitled  to share  pro rata in the net  assets of the Fund
attributable to that class available for distribution to shareholders. The Trust
has  reserved  the right to create  and issue  additional  series or  classes of
shares,  in which case the shares of each  class of a series  would  participate
equally in the  earnings,  dividends  and assets  allocable to that class of the
particular series.
    

Shareholders  are  entitled  to one vote for each share held and may vote in the
election of Trustees and on other matters submitted to meetings of shareholders.
Although  Trustees are not elected  annually by the  shareholders,  shareholders
have under  certain  circumstances  the right to remove one or more  Trustees in
accordance  with the  provisions  of section  16(c) of the 1940 Act. No material
amendment may be made to the Declaration of Trust without the  affirmative  vote
of a majority  of the Trust  shares (as defined in  "Investment  Restrictions").
Shares  have no  pre-emptive  or  conversion  rights  (except  as  described  in
"Purchases -- Conversion of Class B Shares" in the Prospectus). Shares are fully
paid and  non-assessable.  The Fund may be  terminated  (i) upon the  merger  or
consolidation  of the Fund with another  organization or upon the sale of all or
substantially  all  its  assets  if  approved  by the  vote  of the  holders  of
two-thirds of its outstanding shares, except that if the Trustees recommend such
merger, consolidation or sale, the approval by vote of the holders of a majority
of the Fund's outstanding shares will be sufficient or (ii) upon liquidation and
distribution of its assets, if approved by the vote of the holders of two-thirds
of its  outstanding  shares.  If not  so  terminated,  the  Fund  will  continue
indefinitely.

The Trust is an entity of the type commonly known as a  "Massachusetts  business
trust". Under Massachusetts law, shareholders of such a trust may, under certain
circumstances,  be held  personally  liable  as  partners  for its  obligations.
However,  the Declaration of Trust contains an express disclaimer of shareholder
liability for acts or obligations of the Trust and provides for  indemnification
and  reimbursement  of expenses out of Trust property for any  shareholder  held
personally  liable for the  obligations of the Trust.  The  Declaration of Trust
also  provides  that it  shall  maintain  appropriate  insurance  (for  example,
fidelity  bonding and errors and omissions  insurance) for the protection of the
Trust,  its  shareholders,  Trustees,  officers,  employees and agents  covering
possible tort or other  liabilities.  Thus, the risk of a shareholder  incurring
financial loss on account of shareholder  liability is limited to  circumstances
in which both  inadequate  insurance  existed and the Trust itself was unable to
meet its obligations.

The Declaration of Trust further  provides that obligations of the Trust are not
binding upon the Trustees  individually  but only upon the property of the Trust
and that the  Trustees  will not be liable for any action or failure to act, but
nothing in the  Declaration of Trust protects a Trustee against any liability to
which he would otherwise be subject by reason of willful misfeasance, bad faith,
gross negligence or reckless  disregard of the duties involved in the conduct of
his office.

8.  DETERMINATION OF NET ASSET VALUE AND PERFORMANCE

   
NET ASSET  VALUE -- The net asset  value per share of each  class of the Fund is
determined  each day during which the  Exchange is open for trading.  (As of the
date of this SAI, the Exchange is open for trading every weekday  except for the
following  holidays  or days  on  which  they  are  observed:  New  Year's  Day,
Presidents'  Day,  Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving Day and Christmas Day.) This determination is made once each day as
of the close of regular  trading on the Exchange by deducting  the amount of the
liabilities  attributable to the class from the value of the assets attributable
to the class and  dividing the  difference  by the number of shares of the class
outstanding.  Debt  securities  (other than short-term  obligations),  including
listed  issues,  are valued on the basis of  valuations  furnished  by a pricing
service which  utilizes both  dealer-supplied  valuations  and  electronic  data
processing  techniques  which  take into  account  appropriate  factors  such as
institution-size trading in similar groups of securities, yield, quality, coupon
rate, maturity,  type of issue,  trading  characteristics and other market data,
without exclusive reliance upon exchange or over-the-counter  prices, since such
valuations  are  believed  to  reflect  more  accurately  the fair value of such
securities.  Use of the pricing service has been approved by the Fund's Board of
Trustees.  Positions in listed options, Futures Contracts and Options on Futures
Contracts  will  normally be valued at the  settlement  price on the exchange on
which they are  traded.  Short-term  obligations  with a  remaining  maturity in
excess of 60 days will be valued based upon  dealer-supplied  valuations.  Other
short-term  obligations are valued at amortized  cost,  which  constitutes  fair
value as determined  by the Board of Trustees.  If acquired,  preferred  stocks,
common  stocks and warrants will be valued at the last sale price on an exchange
or at the last quoted bid price for unlisted  securities.  Portfolio  securities
for which there are no such quotations or valuations are valued at fair value as
determined  in good faith by or at the  direction  of the Board of  Trustees.  A
share's net asset value is effective for orders  received by the dealer prior to
its calculation and received by MFD prior to the close of that business day.

PERFORMANCE INFORMATION
TOTAL RATE OF RETURN:  The Fund will calculate its total rate of return for each
class of shares for certain periods by determining the average annual compounded
rates of return  over those  periods  that would cause an  investment  of $1,000
(made with all  distributions  reinvested and reflecting the CDSC or the maximum
offering price) to reach the value of that investment at the end of the periods.
The Fund may also calculate (i) a total rate of return,  which is not reduced by
the CDSC (4%  maximum  for Class B shares and  therefore  may result in a higher
rate of return, (ii) a total rate of return assuming an initial account value of
$1,000,  which  will  result in a higher  rate of return  since the value of the
initial  account  will not be reduced by the  maximum  sales  charge  (currently
4.75%), and/or (iii) total rates of return which represent aggregate performance
over a period or year-by-year performance,  and which may or may not reflect the
effect of the maximum or other sales charge or CDSC.  The Fund's  average annual
total rate of return for Class A shares reflecting the initial investment at the
current maximum public  offering price for the one-year,  five-year and ten-year
periods ended January 31, 1995 was -8.45%, 11.28% and 9.06%,  respectively.  The
Fund's  average annual total rate of return for Class A shares not giving effect
to the sales charge on the initial  investment  for the one-year,  five-year and
ten-year  periods  ended  January  31,  1995  was  -3.95%,   12.36%  and  9.59%,
respectively.  The Fund's average annual total rate of return for Class B shares
reflecting  the CDSC for the  one-year  period  ended  January  31, 1995 and the
period from  September 7, 1993  through  January 31, 1995 was -8.29% and -1.52%,
respectively. The Fund's average annual total rate of return for Class B shares,
not giving  effect to the CDSC,  for the one-year  period ended January 31, 1995
and the period from  September 7, 1993  through  January 31, 1995 was -4.77% and
1.45%, respectively.  The Fund's average annual total rate of return for Class C
shares for the  one-year  period  ended  January  31,  1995 and the period  from
January 3, 1994 through January 31, 1995 was -4.51% and -2.22%, respectively.

PERFORMANCE  RESULTS: The performance results below, based on an assumed initial
investment  of $10,000 in Class A shares,  cover the period from January 1, 1985
to December  31,  1994.  It has been  assumed  that  dividends  and capital gain
distributions were reinvested in additional shares.  These performance  results,
as well as any yield or total  rate of return  quotation  provided  by the Fund,
should not be considered as representative of the performance of the Fund in the
future since the net asset value and public offering price of shares of the Fund
will vary based not only on the type,  quality and  maturities of the securities
held in the  portfolio of the Fund,  but also on changes in the current value of
such  securities  and on changes  in the  Fund's  expenses.  These  factors  and
possible  differences in the methods used to calculate yields and total rates of
return should be considered when comparing the yield and total rate of return to
yields and total rates of return  published  for other  investment  companies or
other investment vehicles. Total rate of return reflects the performance of both
principal  and  income.  Current  net  asset  value as well as  account  balance
information may be obtained by calling 1-800-MFS-TALK (637-8255).

EXPLANATORY NOTES: The results assume that the initial investment in the Fund on
January 1, 1985 has been  reduced by the current  applicable  sales  charge.  No
adjustment has been made for any income taxes payable by shareholders.

   
YIELD:  Any  yield  quotation  of a class of  shares of the Fund is based on the
annualized  net investment  income per share  allocated to that class over a 30-
day period.  The yield for each class of the Fund is  calculated by dividing the
net  investment  income  allocated to that class earned during the period by the
maximum  offering  price per share of that  class of the Fund on the last day of
that period. The resulting figure is then annualized.  Net investment income per
share of a class is  determined  by  dividing  (i) the  dividends  and  interest
allocated to that class during the period,  minus accrued expenses of that class
for the period by (ii) the  average  number of shares of the class  entitled  to
receive dividends during the period multiplied by the maximum offering price per
share on the last day of the period.  The Fund's yield  calculations for Class A
shares assume a maximum  sales charge of 4.75%.  The yield for Class A shares of
the Fund for the 30-day period ended January 31, 1995, was 9.78%.  The yield for
Class A shares for the 30-day  period  ended  January  31,  1995 would have been
9.68% excluding  certain fee waivers in effect.  The yield for Class B shares of
the Fund for the 30-day period ended January 31, 1995 was 9.43% (which  includes
the effect of the CDSC). The yield for Class C shares of the Fund for the 30-day
period ended January 31, 1995 was 9.50%.

CURRENT  DISTRIBUTION  RATE: Yield,  which is calculated  according to a formula
prescribed by the Securities and Exchange  Commission,  is not indicative of the
amounts which were or will be paid to the Fund's  shareholders.  Amounts paid to
shareholders  of each class are  reflected in the quoted  "current  distribution
rate" for that class. The current  distribution  rate for a class is computed by
dividing  the  total  amount  of  dividends  per  share  paid  by  the  Fund  to
shareholders  of that class during the past twelve months by the maximum  public
offering  price  of  that  class  at  the  end of  such  period.  Under  certain
circumstances,  such as when there has been a change in the  amount of  dividend
payout, or a fundamental change in investment policies,  it might be appropriate
to annualize  the  dividends  paid over the period such policies were in effect,
rather  than using the  dividends  during the past  twelve  months.  The current
distribution  rate  differs  from the yield  computation  because it may include
distributions  to  shareholders  from sources other than dividends and interest,
such as premium income for option writing,  short-term  capital gains and return
of invested  capital,  and is calculated  over a different  period of time.  The
Fund's  current  distribution  rate  calculation  for  Class A shares  assumes a
maximum sales charge of 4.75%. The Fund's current  distribution rate calculation
for Class B shares assumes no CDSC is paid. The current  distribution  rates for
Class A,  Class B and  Class C shares  of the Fund for the  twelve-month  period
ended on January 31, 1995 was 9.08%, 8.19% and 8.26%, respectively.

From time to time,  the Fund may use charts and  graphs to  illustrate  the past
performance of various indices such as those  mentioned above and  illustrations

The Fund may  advertise  examples of the effects of periodic  investment  plans,
including the principle of dollar cost averaging. In such a program, an investor
invests  a  fixed  dollar  amount  in a  fund  at  periodic  intervals,  thereby
purchasing  fewer  shares  when  prices are high and more shares when prices are
low. While such a strategy does not assure a profit or guard against a loss in a
declining  market,  the  investor's  average cost per share can be lower than if
fixed numbers of shares are purchased at the same intervals.

9.  DISTRIBUTION PLANS
    

The Trustees have adopted a  Distribution  Plan for each of Class A, Class B and
Class C shares (the "Distribution  Plans") 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 each  Distribution Plan would benefit the Fund and
the respective  class of shareholders.  The  Distribution  Plans are designed to
promote sales,  thereby  increasing the net assets of the Fund. Such an increase
may reduce the  expense  ratio to the extent the Fund's  fixed  costs are spread
over a larger net asset  base.  Also,  an  increase in net assets may lessen the
adverse effects that could result were the Fund required to liquidate  portfolio
securities to meet  redemptions.  There is,  however,  no assurance that the net
assets of the Fund will  increase or that the other  benefits  referred to above
will be realized.

   
CLASS A DISTRIBUTION  PLAN: The Class A Distribution Plan provides that the Fund
will pay MFD up to (but not  necessarily  all of) an  aggregate  of 0.35% of the
average daily net assets  attributable  to the Class A shares  annually in order
that MFD may pay expenses on behalf of the Fund related to the  distribution and
servicing of its 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% per annum of the portion of the Fund's average
daily net assets  attributable to the Class A shares owned by investors for whom
that  securities  dealer is the holder or dealer of record.  These  payments are
partial consideration for personal services and/or account maintenance performed
by such dealers with respect to Class A shares. MFD may from time to time reduce
the  amount  of the  service  fee for  shares  sold  prior  to a  certain  date.
Currently,  the  service fee is reduced to 0.15% for shares  purchased  prior to
March 1, 1991.  MFD may also  retain a  distribution  fee of 0.10% of the Fund's
average daily net assets attributable to Class A shares as partial consideration
for  services  performed  and  expenses  incurred  in the  performance  of MFD's
obligations as to Class A shares under the Distribution Agreement with the Fund.
MFD,  however,  is currently  waiving this 0.10%  distribution  fee and will not
accept  payment of this fee unless it first obtains the approval of the Board of
Trustees.  Any remaining funds may be used to pay for other distribution related
expenses  as  described  in the  Prospectus.  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.  No  service  fee will be paid (i) to any  securities  dealer  who is the
holder  or  dealer  of record  for  investors  who own Class A shares  having an
aggregate  net asset value less than  $750,000,  or such other  amount as may be
determined from time to time by MFD (MFD, however, may waive this minimum amount
requirement from time to time if the dealer satisfies certain criteria), or (ii)
to any insurance  company which has entered into an agreement  with the Fund and
MFD that  permits  such  insurance  company to purchase  shares from the Fund at
their net asset value in connection with annuity agreements issued in connection
with the insurance company's separate accounts. Dealers may from time to time be
required to meet certain other 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 agency transaction and service fees
that are the same as commissions and service fees to dealers.  During the fiscal
year ended January 31, 1995 the Fund incurred and  subsequently  waived expenses
of  $531,614  (equal to .10% of its average  daily net  assets)  relating to the
distribution  and servicing of its Class A shares and securities  dealers of the
Fund and certain  banks and other  financial  institutions  received  $1,173,013
(.22% of its average  daily net assets  attributable  to Class A shares) and MFD
retained $284,649.

CLASS B DISTRIBUTION  PLAN:  The Class B  Distribution  Plan relating to Class B
shares (the "Class B Distribution  Plan")  provides that the Fund shall pay MFD,
as the Fund's distributor for its Class B shares, 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% per annum 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
and which are the holders of record of the Fund's Class B shares).  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.  MFD will advance to dealers the first-year  service fee at a rate equal
to 0.25% of the amount invested.  As compensation  therefor,  MFD may retain the
service  fee paid by the Fund with  respect  to such  shares  for the first year
after purchase.  Dealers will become  eligible for additional  service fees with
respect to such shares  commencing in the thirteenth  month following  purchase.
Except in the case of the first year service fee, no service fee will be paid to
any  securities  dealer who is the holder or dealer of record for  investors who
own Class B shares  having an aggregate net asset value of less than $750,000 or
such other amount as may be  determined  from time to time.  MFD,  however,  may
waive this minimum amount  requirement from time to time if the dealer satisfies
certain  criteria.  Dealers may from time to time be  required  to meet  certain
other criteria in order to receive service fees. MFD or its affiliates  shall be
entitled to receive any service fee 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 to shareholder accounts.

The purpose of distribution  payments to MFD under the Class B Distribution Plan
is to  compensate  MFD for its  distribution  services  to the  Fund.  MFD  pays
commissions to dealers as well as expenses of printing  prospectuses and reports
used for sales  purposes,  expenses with respect to the preparation and printing
of sales literature and other distribution related expenses,  including, without
limitation,  the cost necessary to provide  distribution-  related services,  or
personnel,  travel office expenses and equipment.  The Class B Distribution Plan
also  provides  that MFD will receive all CDSCs  attributable  to Class B shares
(see "Distribution Plan" and "Purchase of Shares" in the Prospectus).

During the fiscal year ended  January 31, 1995,  the Fund  incurred  expenses of
$2,960,079  (equal to 1.0% of its  average  daily net  assets)  relating  to the
distribution  and  servicing  of its  Class B  shares,  of  which  MFD  received
$2,221,974 (.75% of its averge daily net assets  attributable to Class B shares)
and  securities  dealers  of the Fund and  certain  banks  and  other  financial
institutions   received   $738,105   (.25%  of  its  average  daily  net  assets
attributable to Class B shares).

CLASS C DISTRIBUTION PLAN: The Distribution Plan relating to Class C shares (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 attibutable to Class C 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% 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 by the dealer 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 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  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  of  printing  prospectuses  and
reports used for sales  purposes,  expenses with respect to the  preparation and
printing of sales literature and other distribution-related expenses, including,
without  limitation,  the  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 to dealers.  Fees payable under the Class C  Distribution  Plan
are charged to, and therefore reduce, income allocated to Class C shares.

During the fiscal year ended  January 31, 1995,  the Fund  incurred  expenses of
$24,572  (equal  to  1.0% of its  average  daily  net  assets)  relating  to the
distribution  and  servicing  of its  Class C  shares,  all of which  securities
dealers of the Fund and certain banks and other financial  institutions received
$24,572 (1.0% of its average daily net assets attributable to Class C shares).

GENERAL:  Each of the  Distribution  Plans will remain in effect until August 1,
1995,  and will  continue  in  effect  thereafter  only if such  continuance  is
specifically  approved  at least  annually  by vote of both the  Trustees  and a
majority  of the  Trustees  who  are not  "interested  persons"  or  financially
interested parties to such Plan ("Distribution Plan Qualified  Trustees").  Each
of the Distribution Plans also requires that the Fund and MFD each shall provide
to the Trustees,  and the Trustees shall review,  at least quarterly,  a written
report of the amounts expended (and purposes  therefor) under such Plan. Each of
the  Distribution  Plans may be  terminated at any time by vote of a majority of
the Distribution Plan Qualified Trustees or by vote of the holders of a majority
of the  respective  class  of the  Fund's  shares  (as  defined  in  "Investment
Restrictions"). All agreements relating to any of the Distribution Plans entered
into  between  the Fund or MFD and other  organizations  must be approved by the
Board of  Trustees,  including a majority  of the  Distribution  Plan  Qualified
Trustees.  Agreements  under any of the  Distribution  Plans must be in writing,
will be terminated  automatically if assigned, and may be terminated at any time
without payment of any penalty,  by vote of a majority of the Distribution  Plan
Qualified  Trustees or by vote of the  holders of a majority  of the  respective
class of the Fund's  shares.  None of the  Distribution  Plans may be amended to
increase  materially the amount of permitted  distribution  expenses without the
approval of a majority of the respective  class of the Fund's shares (as defined
in "Investment Restrictions") or may be materially amended in any case without a
vote of the Trustees and a majority of the Distribution Plan Qualified Trustees.
The selection and nomination of  Distribution  Plan Qualified  Trustees shall be
committed to the discretion of the  non-interested  Trustees then in office.  No
Trustee who is not an "interested  person" has any financial  interest in any of
the Distribution Plans or in any related agreement.

LETTER  TO  SHAREHOLDERS

Dear Shareholders:
During  the fiscal  year  ended  January  31,  1995,  Class A shares of the Fund
provided a total return of -3.95%.  Over the same period,  the total  returns of
Class B and Class C shares were -4.77% and  -4.51%,  respectively.  All of these
returns assume the reinvestment of distributions  but exclude the effects of any
sales charges.  The Fund's results  underperformed the Lehman Brothers Corporate
Bond Index (the Lehman Index),  which  returned  -3.76% during this same period.
Because the Fund's portfolio  generally  consists of lower-quality  issues,  its
results  will not  necessarily  mirror  those of the Lehman  Index,  which is an
unmanaged  market-value  weighted  index  comprised  of all  public  fixed-rate,
non-convertible,  investment-grade  corporate  debt. A discussion of performance
during  1994 as well as our  outlook  for the  months  ahead may be found in the
Portfolio  Performance and Strategy section below. 

Economic Outlook 
The economic expansion,  entering its fifth year, gained firmer underpinnings in
1994 as employers significantly stepped up hiring levels.  Increased employment,
stronger capital spending by businesses,  and strengthening  overseas  economies
resulted in 4% real (adjusted for inflation)  gross domestic product growth last
year.  Interest rates rose  substantially  over the past year, which should help
restrain,  but not curtail, the economic expansion.  Based on improving economic
fundamentals both here and abroad, we expect the business  expansion to continue
well into 1995.

Interest  Rates
Despite a  stronger  economy,  inflation  at the  consumer  level  has  remained
relatively benign at 2.7% in 1994, the fourth straight year of 3.0% or less. Due
to a  prolonged  period of  below-trend-line  growth and  continued  pressure on
corporations  to emphasize  effective cost controls,  wage growth and unit labor
costs have remained subdued.  However,  as the economy has exhibited  continuing
strength,  various  industrial  commodity prices have been rising  substantially
faster  than  consumer  prices.  Nevertheless,  businesses  have had  difficulty
passing these price increases on to the consumer. With the economy continuing to
expand,  we expect some upward movement in inflation from below 3% to the 3 1/2%
range.  The Federal  Reserve Board has shown a willingness  to raise  short-term
rates to slow the economy to dampen inflationary  pressures.  Most recently,  it
raised the federal  funds rate 50 basis points  (0.50%)  after a 75  basis-point
(0.75%) increase in November.  We expect the Federal Reserve to raise short-term
rates again in the coming  months if it believes  that current  efforts have not
been  sufficient  to  dampen  inflationary  expectations.  Although  we  believe
fundamentals  are favorable for lower long-term rates sometime in 1995, this may
not occur  until the  Federal  Reserve is  comfortable  that its  policy  toward
slowing the  economic  expansion  has been  successful.  Thus,  we believe  that
long-term yields may move moderately higher in the near term.

Portfolio  Performance and Strategy 
During the past year,  yield spreads in the  high-yield  market  remained at 375
basis points (3.75%) over  comparable U.S.  Treasuries,  but interest rates rose
dramatically due to increased economic activity which caused the Federal Reserve
to raise the  federal  funds  rate  several  times in an  attempt  to  alleviate
inflationary  pressures. On a relative basis, the high-yield market outperformed
high-grade  bonds as well as  Treasuries,  although it is  important to remember
that principal  value and interest on Treasury  securities are guaranteed by the
U.S. government if held to maturity.  Technicals in the high-yield market remain
uncertain due to volatile  cash flows  experienced  by high-yield  mutual funds,
which account for roughly half the market's  assets and more than  two-thirds of
daily  trading  volume.  As we move into 1995,  the  new-issue  calendar  stands
significantly   below  last  year's   levels  due  to  the  banking   industry's
aggressiveness  in trying to lend money to many companies  which otherwise would
utilize the high-yield bond market for funds.

While  new-issue  quality  declined last year, the average credit quality in the
market  improved as continued  economic  expansion  created an  environment  for
companies  to pay down  their  debt by  either  increased  cash  flows or equity
issuance. During the year, the portfolio remained significantly  overweighted in
economically sensitive companies (paper, metal or general industrial firms), and
underweighted in industries with no pricing leverage due to excess capacity,  or
with  a  high  exposure  to  consumer   demand,   such  as  general   retailing,
transportation  and  utilities  companies.  During 1995,  we expect the economic
climate to continue to be very  healthy for the types of  companies  we own and,
thus, we have not significantly  changed our strategy. We will continue to focus
on fundamental  credit  research,  which is the main factor in  determining  our
investment selection.

We appreciate your support and welcome any questions or comments you may have.

Respectfully,

Chairman and President          Portfolio Manager

PORTFOLIO  MANAGER  PROFILE
Robert Manning began his career at MFS in 1984 as a Research Analyst in the High
Yield  Bond  Department.  A  graduate  of the  University  of Lowell  and Boston
College's  Graduate  School  of  Management,  he  was  named  Vice  President  -
Investments in 1988,  Senior Vice President in 1993 and Portfolio Manager of MFS
High Income Fund in 1994.

OBJECTIVE  AND  POLICIES
The objective of the Fund is to provide high current income  through  investment
primarily in a  professionally  managed,  diversified  portfolio of fixed-income
securities.  Capital  growth,  if  any,  is a  consideration  incidental  to the
objective of high current income.

The Fund seeks to achieve this objective by investing primarily in fixed- income
securities which are in the lower rating categories. The Fund may also invest in
foreign  fixed-income   securities,   purchase  fixed-income   securities  on  a
"when-issued"  basis and enter into options,  futures  transactions  and forward
foreign currency exchange  contracts.  The Fund will seek to reduce risk through
full-time  management of a broadly  diversified  portfolio,  credit analysis and
attention to current  developments  and trends in both the economy and financial
markets.

PERFORMANCE
The  information  below and on the following  page  illustrates  the  historical
performance  of MFS High  Income  Fund Class A shares in  comparison  to various
market  indicators.  Class A share  results  reflect the  deduction of the 4.75%
maximum sales charge; benchmark comparisons are unmanaged and do not reflect any
fees or  expenses.  You  cannot  invest in an index.  All  results  reflect  the
reinvestment of all dividends and capital gains.

Class B shares were offered effective September 27, 1993. Information on Class B
share performance appears on the next page.

Class C shares were offered  effective  January 3, 1994.  Information on Class C
share performance appears on the next page.

*   For the  period  from  the  commencement  of  offering  of  Class B  shares,
    September 27, 1993 to January 31, 1995.

+   The return  reflects the current  maximum Class B contingent  deferred sales
    charge (CDSC) of 4%.

(S) The Consumer Price Index is a popular measure of change in prices.

**  For the period from the commencement of offering of Class C shares,  January
    3, 1994 to January 31, 1995.

In the above table,  we have  included the average  annual total  returns of all
high  current  yield funds  (including  the Fund)  tracked by Lipper  Analytical
Services,  Inc. (an independent firm which reports mutual fund  performance) for
the  applicable  time  periods  (94,  64, 61 and 32 funds for the 1-, 3-, 5- and
10-year periods ended January 31, 1995, respectively).  Because these returns do
not reflect any  applicable  sales  charges,  we have also  included  the Fund's
results at net asset value (no sales charge) for comparison.

All results are  historical  and,  therefore,  are not an  indication  of future
results. The principal value and income return of an investment in a mutual fund
will vary with changes in market conditions,  and shares, when redeemed,  may be
worth  more or less than their  original  cost.  Class C shares  have no initial
sales charge or CDSC but, along with Class B shares, have higher annual fees and
expenses than Class A shares.

All Class A share  results  reflect  the  applicable  expense  subsidy  which is
explained  in the Notes to  Financial  Statements.  Had the  subsidy not been in
effect, the results would have been less favorable. The subsidy may be rescinded
at any time.

TAX FORM  SUMMARY 
In January  1995,  shareholders  were mailed a Tax Form  Summary  reporting  the
federal tax status of all distributions paid during the calendar year 1994.

NOTES  TO  FINANCIAL  STATEMENTS

(1) Business  and  Organization
MFS High Income Fund (the Fund) is a diversified  series of MFS Series Trust III
(the Trust).  The Trust is organized as a  Massachusetts  business  trust and is
registered under the Investment Company Act of 1940, as amended,  as an open-end
management  investment company.  

(2) Significant  Accounting Policies
Investment Valuations - Debt securities (other than short-term obligations which
mature in 60 days or less),  including listed issues and forward contracts,  are
valued on the basis of valuations  furnished by dealers or by a pricing  service
with  consideration  given to  factors  such as  institutional-size  trading  in
similar groups of securities,  yield,  quality,  coupon rate, maturity,  type of
issue, trading characteristics and other market data, without exclusive reliance
upon exchange or over-the-counter prices. Short-term  obligations,  which mature
in 60 days or less,  are valued at amortized  cost,  which  approximates  value.
Non-U.S.  dollar denominated short-term obligations are valued at amortized cost
as  calculated  in the base  currency and  translated  into U.S.  dollars at the
closing daily exchange rate. Futures  contracts,  options and options on futures
contracts  listed on  commodities  exchanges  are valued at  closing  settlement
prices.  Over-the-counter  options  are valued by brokers  through  the use of a
pricing  model  which  takes  into  account  closing  bond  valuations,  implied
volatility  and  short-term   repurchase  rates.  Equity  securities  listed  on
securities  exchanges or reported  through the NASDAQ  system are valued at last
sale prices.  Unlisted equity  securities or listed equity  securities for which
last sale  prices  are not  available  are  valued at last  quoted  bid  prices.
Securities  for which there are no such  quotations or valuations  are valued at
fair value as determined in good faith by or at the direction of the Trustees.

Repurchase  Agreements  - The Fund may enter  into  repurchase  agreements  with
institutions that the Fund's investment adviser has determined are creditworthy.
Each  repurchase  agreement  is recorded  at cost.  The Fund  requires  that the
securities purchased in a repurchase transaction be transferred to the custodian
in a manner  sufficient  to enable the Fund to obtain  those  securities  in the
event of a default under the repurchase agreement. The Fund monitors, on a daily
basis,  the  value of the  securities  transferred  to  ensure  that the  value,
including accrued interest, of the securities under each repurchase agreement is
greater than amounts owed to the Fund under each such repurchase agreement.

Foreign  Currency  Translation  -  Investment  valuations,   other  assets,  and
liabilities  initially  expressed  in  foreign  currencies  are  converted  each
business day into U.S. dollars based upon current exchange rates.  Purchases and
sales of foreign  investments  and income and expenses are  converted  into U.S.
dollars based upon currency exchange rates prevailing on the respective dates of
such  transactions.  Gains and losses  attributable to foreign currency exchange
rates are recorded for financial  statement  purposes as net realized  gains and
losses on investments.  Gains and losses  attributable to foreign  exchange rate
movements on income and expenses are recorded for financial  statement  purposes
as foreign currency  transaction gains and losses. That portion of both realized
and unrealized gains and losses on investments that results from fluctuations in
foreign currency exchange rates is not separately disclosed.

Written  Options  - The Fund may write  covered  call or put  options  for which
premiums  are received and are  recorded as  liabilities,  and are  subsequently
adjusted to the current  value of the options  written.  Premiums  received from
writing  options which expire are treated as realized gains.  Premiums  received
from writing  options which are  exercised or are closed are offset  against the
proceeds or amount paid on the  transaction  to determine  the realized  gain or
loss.  If a put option is exercised,  the premium  reduces the cost basis of the
securities  purchased by the Fund. The Fund, as writer of an option, may have no
control over whether the  underlying  securities may be sold (call) or purchased
(put) and, as a result,  bears the market risk of an  unfavorable  change in the
price of the securities underlying the written option. In general,  written call
options  may  serve  as a  partial  hedge  against  decreases  in  value  in the
underlying securities to the extent of the premium received. Written options may
also be used as part of an income-producing  strategy reflecting the view of the
Fund's management on the direction of interest rates.

Futures  Contracts - The Fund may enter into financial futures contracts for the
delayed delivery of securities, currency or contracts based on financial indices
at a fixed price on a future  date.  In  entering  such  contracts,  the Fund is
required to deposit  either in cash or  securities  an amount equal to a certain
percentage of the contract amount.  Subsequent  payments are made or received by
the Fund  each day,  depending  on the  daily  fluctuations  in the value of the
underlying  security,  and are  recorded  for  financial  statement  purposes as
unrealized  gains or losses by the Fund. The Fund's  investment in interest rate
futures  contracts is designed to hedge against  anticipated  future  changes in
interest rates. The Fund may also invest in exchange rate and securities futures
contracts for non-hedging  purposes.  For example,  interest rate futures may be
used in modifying the duration of the portfolio without incurring the additional
transaction  costs  involved in buying and selling  the  underlying  securities.
Should interest or exchange rates or securities  prices move  unexpectedly,  the
Fund may not achieve the anticipated benefits of the financial futures contracts
and may realize a loss.

Security Loans - The Fund may lend its securities to member banks of the Federal
Reserve  System  and  to  member  firms  of  the  New  York  Stock  Exchange  or
subsidiaries  thereof.  The  loans  are  collateralized  at all times by cash or
securities  with a market value at least equal to the market value of securities
loaned. As with other extensions of credit,  the Fund may bear the risk of delay
in recovery or even loss of rights in the collateral  should the borrower of the
securities  fail  financially.  The Fund receives  compensation  for lending its
securities  in the  form of fees or from all or a  portion  of the  income  from
investment of the collateral. The Fund would also continue to earn income on the
securities loaned. At January 31, 1995, the Fund had no securities on loan.

Forward Foreign  Currency  Exchange  Contracts - The Fund may enter into forward
foreign  currency  exchange  contracts  for the  purchase  or sale of a specific
foreign  currency  at a fixed  price on a future  date.  Risks  may  arise  upon
entering these contracts from the potential  inability of counterparties to meet
the terms of their contracts and from unanticipated  movements in the value of a
foreign currency  relative to the U.S. dollar.  The Fund will enter into forward
contracts for hedging purposes.  The Fund may enter into contracts to deliver or
receive  foreign  currency  it will  receive  from  or  require  for its  normal
investment activities. It may also use contracts in a manner intended to protect
foreign  currency   denominated   securities  from  declines  in  value  due  to
unfavorable  exchange rate  movements.  The forward  foreign  currency  exchange
contracts are adjusted by the daily exchange rate of the underlying currency and
any gains or losses are recorded for financial  statement purposes as unrealized
until the contract settlement date.

Investment Transactions and Income - Investment transactions are recorded on the
trade date.  Interest  income is recorded on the accrual basis.  All premium and
original issue  discount are amortized or accreted for both financial  statement
and tax  reporting  purposes  as  required  by federal  income tax  regulations.
Dividend  income is recorded on the ex-dividend  date for dividends  received in
cash.  Dividend and interest  payments  received in  additional  securities  are
recorded on the ex-dividend or ex-interest  date in an amount equal to the value
of the security on such date.

The  Fund  has  approximately  86%  of  its  portfolio  invested  in  high-yield
securities rated below investment  grade.  Investments in high-yield  securities
are accompanied by a greater degree of credit risk and the risk tends to be more
sensitive to economic conditions than that of higher-rated securities.

The Fund uses the effective  interest  method for reporting  interest  income on
payment-in-kind  (PIK) bonds,  whereby  interest income on PIK bonds is recorded
ratably  by the Fund at a  constant  yield to  maturity.  Legal  fees and  other
related expenses  incurred to preserve and protect the value of a security owned
are added to the cost of the security;  other legal fees are  expensed.  Capital
infusions, which are generally non-recurring, incurred to protect or enhance the
value of  high-yield  debt  securities,  are reported as an addition to the cost
basis of the  security.  Costs  that are  incurred  to  negotiate  the  terms or
conditions  of capital  infusions  or that are  expected  to result in a plan of
reorganization  are  considered  workout  expenses  and are reported as realized
losses.  Ongoing costs  incurred to protect or enhance an  investment,  or costs
incurred to pursue  other  claims or legal  actions,  are  reported as operating
expenses.

Tax  Matters  and  Distributions  - The  Fund's  policy  is to  comply  with the
provisions  of the  Internal  Revenue  Code (the Code)  applicable  to regulated
investment  companies and to distribute to  shareholders  all of its net taxable
income,  including  any  net  realized  gain  on  investments.  Accordingly,  no
provision for federal income or excise tax is provided.

The Fund files a tax return annually using tax accounting methods required under
provisions  of the Code  which may differ  from  generally  accepted  accounting
principles,  the  basis  on  which  these  financial  statements  are  prepared.
Accordingly,  the amount of net investment income and net realized gain reported
on these  financial  statements  may differ from that reported on the Fund's tax
return  and,  consequently,  the  character  of  distributions  to  shareholders
reported  in  the  financial   highlights  may  differ  from  that  reported  to
shareholders on Form 1099-DIV.  Foreign taxes have been provided for on interest
and  dividend  income  earned on  foreign  investments  in  accordance  with the
applicable country's tax rates and to the extent unrecoverable are recorded as a
reduction of investment income.

Distributions  to shareholders  are recorded on the  ex-dividend  date. The Fund
distinguishes  between  distributions  on a tax basis and a financial  reporting
basis and requires that only  distributions  in excess of tax basis earnings and
profits  are  reported  in the  financial  statements  as a return  of  capital.
Differences in the recognition or classification of income between the financial
statements   and  tax   earnings   and  profits   which   result  in   temporary
over-distributions   for  financial  statement   purposes,   are  classified  as
distributions  in excess of net investment  income or  accumulated  net realized
gains. During the year ended January 31, 1995,  accumulated net realized loss on
investments  and  foreign  currency   transactions   increased  by  $14,784,014,
accumulated  distributions  in  excess of net  investment  income  decreased  by
$1,336,380,  and paid-in  capital  decreased by  $13,447,634  due to differences
between book and tax accounting for non-income  producing securities and capital
losses acquired in fund mergers.  This change had no effect on the net assets or
net asset value per share.  At January 31,  1995,  cumulative  tax-basis  income
exceeded  book-basis  income due to  differences  in accounting  for  non-income
producing securities and losses deferred for tax purposes. These differences are
considered temporary and are expected to reverse in future years.

Multiple  Classes of Shares of  Beneficial  Interest - The Fund offers  Class A,
Class B and  Class C  shares.  The  three  classes  of  shares  differ  in their
respective   shareholder   servicing  agent,   distribution  and  service  fees.
Shareholders of each class also bear certain  expenses that pertain only to that
particular class. All shareholders bear the common expenses of the Fund pro rata
based on the  settled  shares  outstanding  of each class,  without  distinction
between share  classes.  Dividends are declared  separately  for each class.  No
class has preferential dividend rights;  differences in per share dividend rates
are  generally  due  to  differences  in  separate  class  expenses,   including
distribution and shareholder servicing fees.

(3) Transactions  with  Affiliates
Investment  Adviser  - The  Fund  has  an  investment  advisory  agreement  with
Massachusetts  Financial  Services  Company (MFS) to provide overall  investment
advisory  and  administrative  services,  and  general  office  facilities.  The
management fee,  computed daily and paid monthly at an effective  annual rate of
0.20% of average  daily net assets and 2.88% of investment  income,  amounted to
$3,756,072.

The Fund pays no  compensation  directly to its Trustees who are officers of the
investment adviser, or to officers of the Fund, all of whom receive remuneration
for their services to the Fund from MFS. Certain of the officers and Trustees of
the Fund are officers or directors of MFS, MFS Fund Distributors, Inc. (MFD) and
MFS Service Center,  Inc. (MFSC).  The Fund has an unfunded defined benefit plan
for all of its independent Trustees. Included in Trustees' compensation is a net
periodic pension expense of $19,892 for the year ended January 31, 1995.

Distributor - MFD, a wholly owned  subsidiary of MFS, as  distributor,  received
$105,333  as its  portion of the sales  charge on sales of Class A shares of the
Fund. The Trustees have adopted  separate  distribution  plans for each class of
shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows:

The Class A Distribution Plan provides that the Fund will pay MFD up to 0.35% of
its 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 its shares. These expenses include a service fee to each securities
dealer  that  enters  into a sales  agreement  with MFD of up to 0.25% per annum
(currently  reduced to 0.15% for shares purchased prior to March 1, 1991) of the
Fund's  average  daily  net  assets  attributable  to Class A shares  which  are
attributable to that securities dealer, a distribution fee to MFD of up to 0.10%
per annum of the Fund's average daily net assets attributable to Class A shares,
commissions to dealers and payments to MFD  wholesalers  for sales at or above a
certain  dollar  level,  and other such  distribution-related  expenses that are
approved by the Fund. MFD is currently waiving the 0.10% distribution fee for an
indefinite  period,  which  amounted to $531,614  and is shown as a reduction of
expenses on the Statement of Operations.  Fees incurred  under the  distribution
plan  during the year  ended  January  31,  1995,  net of waiver,  were 0.22% of
average daily net assets  attributable to Class A shares on an annualized  basis
and amounted to $1,173,013 (of which MFD retained $284,649).

The Class B and Class C Distribution  Plans provide that the Fund will pay MFD a
monthly  distribution fee, equal to 0.75% per annum, and a quarterly service fee
of up to 0.25% per annum, of the Fund's average daily net assets attributable to
Class B and Class C shares.  MFD will pay to each securities  dealer that enters
into a sales agreement with MFD all or a portion of the service fee attributable
to Class B and Class C shares,  and will pay to such  securities  dealers all of
the distribution fee attributable to Class C shares. The service fee is intended
to be additional  consideration for services rendered by the dealer with respect
to Class B and Class C shares. Fees incurred under the distribution plans during
the year  ended  January  31,  1995  were  1.00% of  average  daily  net  assets
attributable  to Class B and Class C shares on an annualized  basis and amounted
to $2,960,079 and $24,572,  respectively (of which MFD retained $83,028 and $759
for Class B and Class C  shares,  respectively).

A contingent  deferred  sales charge is imposed on  shareholder  redemptions  of
Class A shares,  on  purchases  of $1 million  or more,  in the event of a share
redemption  within twelve  months  following  the share  purchase.  A contingent
deferred sales charge is imposed on shareholder redemptions of Class B shares in
the event of a share redemption  within six years of purchase.  MFD receives all
contingent  deferred sales charges.  Contingent  deferred sales charges  imposed
during the year ended  January 31, 1995 were $303 and  $578,443  for Class A and
Class B shares, respectively.

Shareholder  Servicing  Agent - MFSC, a wholly owned  subsidiary of MFS,  earned
$789,656,  $651,780  and  $3,689  for  Class  A,  Class B and  Class  C  shares,
respectively,  for its  services  as  shareholder  servicing  agent.  The fee is
calculated  as a  percentage  of the  average  daily net assets of each class of
shares at an effective  annual rate of up to 0.15%,  up to 0.22% and up to 0.15%
attributable to Class A, Class B and Class C shares, respectively.

(4) Portfolio  Securities  Purchases and sales of  investments,  other than U.S.
government securities, purchased option transactions and short-term obligations,
aggregated $467,033,436 and $599,003,642, respectively.

The cost and unrealized appreciation or depreciation in value of the investments
owned by the Fund, as computed on a federal income tax basis, are as follows:

Aggregate cost                                                  $ 892,675,204

At January 31, 1995, the Fund,  for federal  income tax purposes,  had a capital
loss carryforward of $236,557,241,  which may be applied against any net taxable
realized gains of each  succeeding  year until the earlier of its utilization or
expiration.  The Fund's  carryforward  losses  expire as shown in the  following

(6) Line of Credit 

The Fund entered into an agreement  which enables it to  participate  with other
funds  managed by MFS, or an affiliate  of MFS, in an  unsecured  line of credit
with  a  bank  which  permits  borrowings  up  to  $300  million,  collectively.
Borrowings  may be made to  temporarily  finance the  repurchase of Fund shares.
Interest is charged to each fund,  based on its  borrowings,  at a rate equal to
the bank's base rate. In addition,  a commitment fee, based on the average daily
unused portion of the line of credit, is allocated among the participating funds
at the end of each  quarter.  The  commitment  fee allocated to the Fund for the
year ended January 31, 1995 was $13,109.

(7)  Transactions  in  Securities  of  Affiliated  Issuers  

Affiliated  issuers,  as defined under the  Investment  Company Act of 1940, are
those in which the  Fund's  holdings  of an issuer  represent  5% or more of the
outstanding   voting   securities  of  the  issuer.  A  summary  of  the  Fund's
transactions  in the  securities of these issuers  during the year ended January
31, 1995 is set forth below.

INDEPENDENT  AUDITORS'  REPORT

To the  Trustees  of MFS Series  Trust III and  Shareholders  of MFS High Income
Fund:  

We have audited the accompanying statement of assets and liabilities,  including
the  portfolio  of  investments,  of MFS High  Income  Fund  (one of the  series
constituting MFS Series Trust III) as of January 31, 1995, the related statement
of  operations  for the year then ended,  the statement of changes in net assets
for the years ended  January 31, 1995 and January 31,  1994,  and the  financial
highlights for each of the years in the ten-year  period ended January 31, 1995.
These financial  statements and financial  highlights are the  responsibility of
the  Fund's  management.  Our  responsibility  is to express an opinion on these
financial statements and financial highlights based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether the  financial  statements  and  financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis,  evidence  supporting  the amounts and  disclosures in the financial
statements.  Our procedures  included  confirmation  of the securities  owned at
January 31, 1995 by correspondence with the custodian and brokers; where replies
were not received from brokers, we performed other auditing procedures. An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  such  financial  statements  and financial  highlights  present
fairly, in all material respects, the financial position of MFS High Income Fund
at January  31,  1995,  the  results of its  operations,  the changes in its net
assets,  and its  financial  highlights  for the  respective  stated  periods in
conformity with generally accepted accounting principles.

<F2>The Fund has adopted a Distribution  Plan for its Class B 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

    permissible if imposed entirely as an initial sales charge.

2.  THE FUND
The Fund is a  non-diversified  series  of the  Trust,  an  open-end  management
investment company which was organized as a business trust under the laws of The
Commonwealth  of  Massachusetts  in 1977.  The Trust  presently  consists of two
series, each of which represents a portfolio with separate investment  policies.
Two  classes of shares of the Fund are offered to the  general  public.  Class A
shares are offered at net asset value plus an initial sales charge (or a CDSC in
the case of certain purchases of $1 million or more). 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 and service fee. Class B
shares will convert to Class A shares  approximately eight years after purchase.
The Fund buys securities (primarily municipal bonds and notes that may be in the
medium or lower rating  categories  or may be unrated,  the interest on which is
exempt from federal income tax) for its portfolio.

In June 1985, the Trust's Board of Trustees  decided to terminate  sales of Fund
shares,  other than to the Fund's  shareholders,  because the Fund had  attained
optimal size for management purposes. The Board of Trustees voted to re-open the
Fund for sales to new  shareholders  for the  period  from  March 1, 1989 to the
close of  business on March 23,  1989.  During such period the Fund's net assets
increased  by  approximately  $109  million  as  a  result  of  such  additional
investments.  The Board of Trustees voted again to re-open the Fund for sales to
new  shareholders  for the period from February 6, 1990 to the close of business
on February 7, 1990.  During such  period,  the Fund's net assets  increased  by
approximately  $205  million  as a result  of such  additional  investments.  On
February 28, 1990, the sale of Fund shares to existing  shareholders (other than
through  the  reinvestment  of  dividends  and  capital  gains of the  Fund) was
terminated.  On November 5, 1990,  Fund shares were made  available  for sale to
existing  shareholders only. Upon a vote by the Board of Trustees,  the Fund was
again reopened for sales to new shareholders  for one day, June 3, 1994.  During
such day,  the Fund's net assets  increased by  approximately  $189 million as a
result of such additional investments.

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

4.  INVESTMENT OBJECTIVE AND POLICIES
INVESTMENT  OBJECTIVE -- The investment objective of the Fund is to provide high
current  income exempt from federal income taxes.  Any investment  involves risk
and  there  can be no  assurance  that  the Fund  will  achieve  its  investment
objective.

INVESTMENT  POLICIES -- The Fund seeks to achieve its  investment  objective  by
investing   primarily   (i.e.,   at  least  80%  of  its  assets   under  normal
circumstances) in debt securities issued by or on behalf of states,  territories
and  possessions  of the United  States,  the  District  of  Columbia  and their
political subdivisions, agencies or instrumentalities,  the interest on which is
exempt from federal income tax ("Municipal  Bonds" or "tax-exempt  securities").
Under  normal  circumstances,  the Fund  will  invest  at least 65% of its total
assets in tax-exempt securities which offer a current yield above that generally
available on tax-exempt securities in the three highest rating categories of the
recognized  rating  agencies  (commonly known as "junk bonds" if rated below the
four  highest  categories  of  recognized  rating  agencies).   Such  high  risk
securities  generally  involve  greater  volatility of price and greater risk of
nonpayment of principal and interest (including the possibility of default by or
bankruptcy of the issuers of such  securities)  than securities in higher rating
categories.  See "Risk  Factors"  below for a further  description  of the risks
associated  with  these  medium  and  lower  rated  securities.  However,  since
available  yields and yield  differentials  vary over time, no specific level of
income or yield  differential  can ever be assured.  Also,  any income earned on
portfolio  securities  would be reduced by the expenses of the Fund before it is
distributed to shareholders.

   
The Fund may purchase  Municipal  Bonds, the interest on which may be subject to
an  alternative  minimum tax (for the purpose of this  Prospectus,  the interest
thereon is nonetheless considered to be tax-exempt).  For a comparison of yields
on Municipal Bonds and taxable  securities,  see Appendix A to this  Prospectus;
for a general  discussion  of  Municipal  Bonds  and a  description  of  Moody's
Investors Service, Inc. ("Moody's"), Standard & Poor's Ratings Group ("S&P") and
Fitch Investors Service, Inc. ("Fitch") ratings of Municipal Bonds, see Appendix
B to this  Prospectus;  and for a chart  indicating the  composition of the bond
portion of the Fund's  portfolio  for its most recent  fiscal year with the debt
securities separated into rating categories, see Appendix C to this Prospectus.
    

The value of the tax-exempt  securities that the Fund intends to purchase may be
less sensitive to market  factors than other  securities;  however,  they may be
more  sensitive  to changes  in the  perception  of the  credit  quality of such
securities, or of similar types of securities or of securities issued within the
same geographical region. Changes in the value of securities subsequent to their
acquisition will not affect income or yields to maturity of the Fund's portfolio
securities  but will be  reflected  in the net asset  value of the shares of the
Fund.  In order to preserve or enhance  the value of its  investments,  the Fund
may, on occasion,  make additional capital  expenditures beyond the initial cost
of an  investment.  The Fund will seek to reduce risk  through  diversification,
credit  analysis and  attention to current  developments  and trends in both the
economy and financial markets.

The net asset value of the shares of an open-end investment company, such as the
Fund, which invests primarily in fixed income tax-exempt securities,  changes as
the general levels of interest rates fluctuate. When interest rates decline, the
value  of a  portfolio  invested  at  higher  yields  can be  expected  to rise.
Conversely, when interest rates rise, the value of a portfolio invested at lower
yields can be expected to decline.

When the Adviser believes that investing for defensive  purposes is appropriate,
such as during  periods  of  unusual  market  conditions  or at times when yield
spreads are narrow and the higher yields do not justify the increased risk or if
acceptable  quantities of higher yielding  securities are unavailable,  the Fund
may either  invest in tax-exempt  securities in the higher rating  categories of
recognized  rating agencies (that is, ratings of A or higher by Moody's,  S&P or
Fitch or comparable unrated tax-exempt securities) or in cash or cash equivalent
short-term obligations of similar quality (i.e., with ratings equivalent to A or
better by Moody's,  S&P or Fitch or comparable  unrated  tax-exempt  securities)
including, but not limited to, short-term municipal obligations, certificates of
deposit, commercial paper, short-term notes, obligations issued or guaranteed by
the U.S. Government or any of its agencies or  instrumentalities  and repurchase
agreements.  From time to time,  a portion of the Fund's  distributions  will be
taxable to shareholders (e.g., distributions of income from taxable obligations,
from capital gains,  from  transactions in certain  Municipal Bonds purchased at
market discount and from certain other transactions).

   
The Fund may invest in a relatively high percentage of municipal bonds issued by
entities having similar characteristics.  The issuers may be located in the same
geographic  area,  or may pay  interest  on their  obligations  from  revenue of
similar  projects  such as hospitals,  electric  utility  systems,  multi-family
housing,   nursing  homes,   commercial  facilities  (including  hotels),  steel
companies or life care  facilities.  This may make the Fund more  susceptible to
similar  economic,  political or regulatory  occurrences.  As the  similarity in
issuers  increases,  the  potential  for  fluctuation  of the net asset value of
shares of the Fund also increases.
    

The Fund  reserves the right to invest more than 25% of its assets in industrial
revenue bonds, including industrial revenue bonds issued for hospitals, electric
utility systems,  multi-family  housing,  nursing homes,  commercial  facilities
(including hotels), steel companies and life care facilities.  See the Statement
of Additional  Information for a discussion of the risks which these investments
might entail.  Certain of the bonds issued for these purposes provide  financing
for  construction or  rehabilitation  of facilities as described  above. As such
they are  susceptible to various  construction  related risks,  including  labor
costs and environmental,  zoning and site development considerations, as well as
the ability of contractors to perform within time and cost constraints.

From  time to time,  proposals  have been  introduced  before  Congress  for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on Municipal  Bonds.  See "Tax Status"  below for the effect of current
federal tax law on this exemption.

ZERO COUPON  BONDS:  Municipal  Bonds in which the Fund may invest also  include
zero coupon bonds.  Zero coupon bonds are debt obligations which are issued at a
significant  discount from face value and do not require the periodic payment of
interest.  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.  Zero coupon bonds 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.  Because of
the  higher  rates of  return,  such  investments  are  regarded  by the Fund as
consistent with its investment objective.

INVERSE  FLOATING RATE  OBLIGATIONS:  The Fund may invest in so called  "inverse
floating rate obligations" or "residual interest" bonds, or other obligations or
certificates  relating  thereto  structured  to  have  similar  features.   Such
obligations  generally have floating or variable interest rates that move in the
opposite  direction  of  short-term  interest  rates and  generally  increase or
decrease in value in response to changes in short-term  interest rates at a rate
which is a multiple  (typically two) of the rate at which  fixed-rate  long-term
tax-exempt  securities  increase or decrease in response to such  changes.  As a
result,  such obligations have the effect of providing  investment  leverage and
may be more volatile than long-term fixed rate tax exempt obligations.

   
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 risk.

LOANS AND OTHER DIRECT INDEBTEDNESS: The Fund may invest a portion of its assets
in loans. By purchasing a loan, the Fund acquires some or all of the interest of
a bank or other lending institution in a loan to a corporate 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 and services.  These claims may
also be purchased at a time when the company is in default. Certain of the loans
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.  Loans 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 loans and the risks related to transactions therein,
see the Statement of Additional Information.

"WHEN-ISSUED"  SECURITIES:  Some  tax-exempt  securities  may be  purchased on a
"when-issued" or on a "forward delivery" basis, which means that the obligations
will be  delivered  to the  Fund at a  future  date,  usually  beyond  customary
settlement time. The commitment to purchase a security for which payment will be
made on a future date may be deemed a separate  security.  Although  the Fund is
not  limited as to the  amount of  tax-exempt  securities  for which it has such
commitments,  it is expected that under normal circumstances,  the Fund will not
commit more than 30% of its assets to such purchases.  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  short-term   securities  that  offer  same-day
settlement  and  earnings,  but that  may bear  interest  at a lower  rate  than
longer-term  securities;  however,  the Fund  also  may  invest  in  longer-term
securities.  It is the intention of the Fund that these investments will usually
be in  securities  the interest on which is exempt from federal  income tax. For
additional  information concerning the use, risks and costs of "when-issued" and
"forward delivery" securities, see the Statement of Additional Information.

   
INDEXED  SECURITIES:  The Fund may invest in indexed  securities  whose value is
linked to 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 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.

OPTIONS:  The Fund  intends to write  (sell)  "covered"  put and call options on
fixed income  securities.  Call options  written by the Fund give the holder the
right to buy the underlying  securities  from the Fund at a fixed exercise price
up to a stated expiration date or, in the case of certain options, on such date.
Put options written by the Fund give the holder the right to sell the underlying
securities to the Fund during the term of the option at a fixed  exercise  price
up to a stated expiration date or, in the case of certain options, on such date.
Call options are "covered" by the Fund, for example, when it owns the underlying
securities,  and put options are "covered" by the Fund, for example, when it has
established a segregated  account of cash or short-term money market instruments
which can be  liquidated  promptly  to  satisfy  any  obligation  of the Fund to
purchase  the  underlying   securities.   The  Fund  may  also  write  straddles
(combinations  of  puts  and  calls  on  the  same  underlying  security).  Such
transactions generate additional premium income but also include greater risk.
    

The Fund will  receive  a  premium  from  writing  a put or call  option,  which
increases the Fund's gross income in the event the option expires unexercised or
is closed out at a profit.  The amount of the premium will reflect,  among other
things,  the  relationship  of the  exercise  price  to  the  market  price  and
volatility of the underlying security,  the remaining term of the option, supply
and demand and interest  rates.  By writing a call  option,  the Fund limits its
opportunity  to profit from any increase in the market  value of the  underlying
security  above the exercise price of the option.  By writing a put option,  the
Fund  assumes  the risk  that it may be  required  to  purchase  the  underlying
security  for an exercise  price  higher  than its  then-current  market  value,
resulting  in  a  potential  capital  loss  unless  the  security   subsequently
appreciates in value.

The Fund may terminate an option that it has written prior to its  expiration by
entering  into a closing  purchase  transaction  in which it purchases an option
having the same terms as the  option  written.  It is  possible,  however,  that
illiquidity  in the options  markets may make it difficult from time to time for
the Fund to close out its written option positions.

The Fund may also  purchase  put or call options in  anticipation  of changes in
interest  rates which may  adversely  affect the value of its  portfolio  or the
prices of  securities  that the Fund  wants to  purchase  at a later  date.  The
premium paid for a put or call option plus any transaction costs will reduce the
benefit,  if any, realized by the Fund upon exercise of the option,  and, unless
the price of the underlying security changes sufficiently, the option may expire
without value to the Fund.

The Fund  intends  to write and  purchase  options  on  securities  for  hedging
purposes and also in an effort to increase current income. Options on securities
that are written or purchased by the Fund will be traded on U.S.
exchanges and over-the-counter.

   
The Fund may purchase detachable call options on municipal securities, which are
options issued by an issuer of the underlying  municipal  securities  giving the
purchaser the right to purchase the securities at a fixed price,  up to a stated
time in the future, or in some cases, on a future date.
    

In  addition,  the Fund may  purchase  warrants on fixed  income  securities.  A
warrant on a fixed income security is a long-dated call option  conveying to the
holder of the warrant  the right,  but not the  obligation,  to purchase a fixed
income security of a specific description (from the issuer) on a certain date or
dates (the exercise date) at a fixed exercise price.

FUTURES  CONTRACTS AND OPTIONS ON FUTURES  CONTRACTS:  The Fund may purchase and
sell futures contracts on fixed income securities or indices of such securities,
including  Municipal  Bond  indices  and  any  other  indices  of  fixed  income
securities which may become  available for trading  ("Futures  Contracts").  The
Fund may also purchase and write options on such Futures Contracts  ("Options on
Futures Contracts"). These instruments will be used to hedge against anticipated
future changes in interest rates which otherwise might either  adversely  affect
the value of the Fund's  portfolio  securities or adversely affect the prices of
securities  which the Fund intends to purchase at a later date.  Should interest
rates move in an  unexpected  manner,  the Fund may not achieve the  anticipated
benefits of the hedging  transactions and may realize a loss. Such  transactions
may also be entered  into for  non-hedging  purposes to the extent  permitted by
applicable  law, which involves  greater risk and may result in losses which are
not offset by gains on other portfolio assets.

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

The Fund has adopted the  additional  restriction  that it will not enter into a
Futures Contract if, immediately  thereafter,  the value of securities and other
obligations  underlying all such Futures Contracts would exceed 50% of the value
of the Fund's total  assets.  Moreover,  the Fund will not purchase put and call
options on securities or on Futures Contracts,  if as a result,  more than 5% of
its total assets would be invested in such options.

Futures Contracts and Options on Futures Contracts that are entered into by
the Fund will be traded on U.S. exchanges.

RISK FACTORS: Although the Fund will enter into certain transactions in options,
Futures Contracts and Options on Futures  Contracts for hedging  purposes,  such
transactions  nevertheless  involve  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 and Options on Futures
Contracts for other than hedging purposes, to the extent permitted by applicable
law, which involves greater risk. In addition,  there can be no assurance that a
liquid secondary  market will exist for any contract  purchased or sold, and the
Fund may be required to maintain a position until exercise or expiration,  which
could result in losses.  The  Statement  of  Additional  Information  contains a
further  description  of  options,  Futures  Contracts  and  Options  on Futures
Contracts,  and a  discussion  of the risks  related  to  transactions  therein.
Transactions  entered into for  non-hedging  purposes  involve  greater risk and
could result in losses which are not offset by gains on other portfolio assets.

Transactions in options may be entered into on U.S.  exchanges  regulated by the
SEC and in the  over-the-counter  market, while Futures Contracts and Options on
Futures Contracts may be entered into on U.S. commodities exchanges regulated by
the CFTC.  Over-the-counter  transactions involve certain risks which may not be
present in exchange-traded transactions.

Gains  recognized from options and futures  transactions  engaged in by the Fund
are taxable to shareholders upon distribution.

PORTFOLIO  TRADING:  The Fund intends to engage in portfolio trading rather than
holding all portfolio securities to maturity.  In trading portfolio  securities,
the Fund seeks to take advantage of market  developments,  yield disparities and
variations in the creditworthiness of issuers.

   
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
as a  factor  in the  selection  of  broker-dealers  to  execute  the  portfolio
transactions  of the Fund.  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 Trading" in the Fund's Statement of Additional Information.
    


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

The investment objective and policies of the Fund described above may be changed
without shareholder approval.

The  Statement  of  Additional   Information  includes  a  discussion  of  other
investment  policies  and a listing of specific  investment  restrictions  which
govern the investment policies of the Fund. Except as otherwise  indicated,  the
Fund's specific  investment  restrictions  listed in the Statement of Additional
Information may not be changed  without the approval of the  shareholders of the
Fund.

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

5.  RISK FACTORS
Tax-exempt  securities  offering the high current  income sought by the Fund are
ordinarily  in the medium  and lower  rating  categories  of  recognized  rating
agencies or are  unrated  and,  therefore,  generally  are high risk  securities
involving  greater  volatility of price  (especially  during periods of economic
uncertainty  or change) and risk of  principal  (including  the  possibility  of
default by or  bankruptcy  of the  issuers of such  securities)  and income than
securities in the higher rating categories and because yields vary over time, no
specific  level of income can ever be assured.  No minimum rating is required by
the Fund. In particular,  securities rated BBB by S&P or Fitch or Baa by Moody's
or comparable unrated securities,  while normally exhibiting adequate protection
parameters,  have speculative characteristics and changes in economic conditions
and other  circumstances  are more likely to lead to a weakened capacity to make
principal  and  interest  payments  than in the case of higher  grade  Municipal
Bonds.  Securities  rated  lower  than BBB by S&P or Fitch or Baa by  Moody's or
comparable unrated securities (high risk securities) are considered speculative.
While  such  high  risk   securities   may  have  some  quality  and  protective
characteristics, they can be expected to be outweighed by large uncertainties or
major  risk  exposures  to adverse  conditions.  These  Municipal  Bonds will be
affected by the market's  perception of their credit quality,  economic  changes
and the  outlook for  economic  growth to a greater  extent  than  higher  rated
securities  which  react  primarily  to  fluctuations  in the  general  level of
interest  rates.  Medium and lower rated  Municipal  Bonds are also  affected by
changes in interest  rates,  as noted in  "Investment  Objective  and  Policies"
above.  Furthermore,  an economic  downturn may result in a higher  incidence of
defaults by issuers of these  securities.  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.

   
In  addition,  medium  and lower  rated or  unrated  tax-exempt  securities  are
frequently  traded only in markets where the number of potential  purchasers and
sellers, if any, is very limited. Furthermore, the liquidity of these securities
may be affected by the  market's  perception  of the  issuer's  credit  quality.
Therefore, judgment may at times play a greater role in valuing these securities
than in the case of higher grade tax-exempt  securities.  This consideration may
also have the effect of limiting the  availability  of such  securities  for the
Fund to  purchase  and may also have the effect of  limiting  the ability of the
Fund to sell such  securities  at their  fair  value  either to meet  redemption
requests or to respond to changes in the economy or the financial markets.
    

While the  Adviser  may refer to ratings  issued by  established  credit  rating
agencies, it is not the policy of the Fund to rely exclusively on ratings issued
by these agencies,  but rather to supplement such ratings with the Adviser's own
independent and ongoing review of credit quality.  The Fund's achievement of its
investment  objective may be more dependent on the Adviser's own credit analysis
than in the case of an investment  company investing in primarily higher quality
bonds.  With respect to those municipal bonds and notes which are not rated by a
major rating  agency,  the Fund will be more reliant on the Adviser's  judgment,
analysis  and  experience  than  would be the case if such  bonds and notes were
rated.  In  evaluating  the  creditworthiness  of an  issuer,  whether  rated or
unrated,  the Adviser  will take into  consideration,  among other  things,  the
issuer's financial resources, its sensitivity to economic conditions and trends,
any operating  history of and the community support for the facility financed by
the issue, the ability of the issuer's management and regulatory matters.

The Adviser  will  attempt to reduce the risks of  investing  in medium or lower
rated or  unrated  tax-exempt  securities  to the  greatest  extent  practicable
through  portfolio  management  techniques  (see  the  Statement  of  Additional
Information) and through the use of credit analysis and Futures Contracts.

The Fund has  registered as a  "non-diversified"  investment  company so that it
will be able to invest  more  than 5% of its  assets  in the  obligations  of an
issuer,  subject to the  diversification  requirements  of  Subchapter  M of the
Internal  Revenue  Code of  1986,  as  amended.  Since  the  Fund  may  invest a
relatively  high percentage of its assets in the obligations of a limited number
of issuers,  the Fund may be more susceptible to any single economic,  political
or regulatory occurrence than a diversified investment company.

For the above reasons, an investment in shares of the Fund should not constitute
a complete  investment  program and may not be  appropriate  for  investors  who
cannot  assume the  greater  risk of capital  depreciation  or loss  inherent in
seeking higher tax-exempt yields.

6.  MANAGEMENT OF THE FUND
INVESTMENT  ADVISER  -- MFS  manages  the  assets  of the  Fund  pursuant  to an
Investment  Advisory  Agreement  dated  September 1, 1993. MFS provides the Fund
with overall investment advisory and administrative services, as well as general
office facilities. Cynthia M. Brown, a Senior Vice President of the Adviser, has
been the  Fund's  portfolio  manager  since  1993 and has been  employed  by the
Adviser since 1984. Subject to such policies as the Trustees may determine,  MFS
makes investment decisions for the Fund. For these services and facilities,  MFS
receives a management fee, computed and paid monthly,  in an amount equal to the
sum of 0.30% of the Fund's  average  daily net  assets  plus 4.75% of the Fund's
gross income (i.e., income other than from the sale of securities), in each case
on an annualized basis, for the Fund's then-current fiscal year.

   
For the Fund's fiscal year ended January 31, 1995, MFS received  management fees
under the Fund's Investment Advisory Agreement of $6,385,098.

MFS also  serves as  investment  adviser  to each of the other  funds in the MFS
Family  of  Funds  (the  "MFS  Funds"),  to  MFS  Municipal  Income  Trust,  MFS
Multimarket  Income Trust, MFS Government Markets Income Trust, MFS Intermediate

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
founding of the first mutual fund in the United States,  Massachusetts Investors
Trust.   Net  assets  under  the  management  of  the  MFS   organization   were
approximately  $35.4  billion on behalf of  approximately  1.7 million  investor
accounts as of April 28, 1995.  As of such date,  the MFS  organization  managed
approximately   $6.5  billion  of  assets  in  municipal  bond   securities  and
approximately $19 billion of assets in fixed income securities.  MFS is a wholly
owned  subsidiary of Sun Life of Canada (U.S.),  which in turn is a wholly owned
subsidiary of Sun Life Assurance  Company of Canada ("Sun Life").  The Directors
of MFS are A. Keith Brodkin,  Jeffrey L. Shames, John R. Gardner, John D. McNeil
and Arnold D. Scott.  Mr.  Brodkin is the Chairman,  Mr. Shames is the President
and Mr. Scott is a Senior  Executive  Vice  President  and the Secretary of MFS.
Messrs. McNeil and Gardner are the Chairman and the President,  respectively, of
Sun Life.  Sun Life,  a mutual  life  insurance  company,  is one of the largest
international  life  insurance  companies  and has been  operating in the United
States  since  1895,  establishing  a  headquarters  office  here in  1973.  The
executive officers of MFS report to the Chairman of Sun Life.

shares  of the Fund and also  serves  as  distributor  for each of the other MFS
Funds.
    

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



7.  INFORMATION CONCERNING SHARES OF THE FUND

   
PURCHASES
Only existing  shareholders of the Fund may purchase Class A and Class B shares.
Because of this restriction, certain dealers in the past have transferred and in
the  future  may  transfer  a share of the  Fund to  certain  of  their  clients
interested in becoming  shareholders  of the Fund so that such clients will then
be able to buy additional shares of the Fund.  Subject to the above restriction,
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, the Fund's  principal  underwriter.  Non-securities  dealer
financial  institutions  will  receive  transaction  fees  that  are the same as
commissions to dealers.  Securities dealers and other financial institutions may
also charge their customers service fees relating to investments in the Fund.

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

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

<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 will pay a commission on purchases of $1 million or more.
</TABLE>

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

In determining whether a CDSC on such Class A shares is payable, and, if so, the
amount of the charge,  it is assumed that shares not subject to the CDSC are the
first redeemed followed by other shares held for the longest period of time. All
investments  made during a calendar  month,  regardless of when during the month
the  investment  occurred,  will age one  month on the last day of the month and
each subsequent month. Except as noted below, the CDSC on Class A shares will be
waived in the case of: (i)  exchanges  (except  that if the shares  acquired  by
exchange were then redeemed within 12 months of the initial purchase (other than
in connection  with subsequent  exchanges to other MFS Funds),  the charge would
not be waived);  (ii)  distributions  to  participants  from a  retirement  plan
qualified under 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 plans;  (iii)  distributions
from a 403(b) plan or an  Individual  Retirement  Account  ("IRA") due to death,
disability  or  attainment  of age 59  1/2;  (iv)  tax-free  returns  of  excess
contributions  to an IRA; (v)  distributions  by other employee benefit plans to
pay  benefits;  and (vi) certain  involuntary  redemptions  and  redemptions  in
connection with certain automatic  withdrawals from a qualified retirement plan.
The CDSC on Class A shares will not be waived,  however,  if the Retirement Plan
withdraws from the Fund except if that  Retirement  Plan has invested its assets
in Class A shares of one or more of the MFS  Funds  for more than 10 years  from
the later to occur of (i) January 1, 1993 or (ii) the date such  Retirement Plan
first invests its assets in Class A shares of one or more of the MFS Funds,  the
CDSC on Class A shares will be waived in the case of a redemption  of all of the
Retirement  Plan's shares (including shares of any other class) in all MFS Funds
(i.e.,  all the  assets of the  Retirement  Plan  invested  in the MFS Funds are
withdrawn),  unless,  immediately prior to the redemption,  the aggregate amount
invested by the  Retirement  Plan in Class A shares of the MFS Funds  (excluding
the reinvestment of distributions)  during the prior four year period equals 50%
or more of the total value of the Retirement  Plan's assets in the MFS Funds, in
which  case the  CDSC  will not be  waived.  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\s/\m/ 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\s/\m/  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. In addition,  MFD pays a commission to dealers
who initiate and are responsible for purchases of $1 million or more as follows:
1.00% on sales up to $5  million,  plus  0.25% on the  amount  in  excess  of $5
million.  Purchases of $1 million or more for each  shareholder  account will be
aggregated  over a 12-month period  (commencing  from the date of the first such
purchase) for purposes of determining  the level of commission to be paid during
that period with respect to such account. 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.

If available for sale, 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 and former
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,  if available  for sale,  may 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 the MFS
Asset Management, Inc.

If available for sale, 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 also be sold at net  asset  value  where  the  amount  invested
represents  redemption  proceeds  from the MFS Fixed  Fund.  Class A shares,  if
available  for  sale,  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 purchase
Class A shares of the Fund,  if avaliable for sale, at their net asset value per
share.  Class A shares of the Fund if available for sale 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 if  available  for  sale  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 if available  for sale 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 if available  for sale may be sold at net asset value
through the automatic  reinvestment  of  distirbutions  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 a percentage of the lesser of the original
purchase price or redemption proceeds as follows:

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

   
The CDSC on Class B shares  will be  waived  upon the  death or  disability  (as
defined in Section  72(m)(7) of the Code) of any investor,  provided the account
is registered (i) in the case of a deceased  individual,  solely in the deceased
individual's name, (ii) in the case of a disabled individual,  solely or jointly
in the disabled individual's name or (iii) in the name of a living trust for the
benefit of the deceased or disabled individual.  The CDSC on Class B shares will
also be waived in the case of  redemptions  of shares of the Fund  pursuant to a
Systematic  Withdrawal  Plan.  In  addition,  the CDSC on Class B shares will be
waived in the case of distributions from an IRA, SAR-SEP or any other retirement
plan  qualified  under  sections  401(a)  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 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  redemptions  by (i)  officers  of the  Trust,  (ii) any of the
subsidiary companies of Sun Life, (iii) eligible Directors,  officers, employees
(including  retired and former  employees) and agents of MFS, Sun Life or any of
their subsidiary companies, (iv) any trust, pension, profit-sharing or any other
benefit plan for such  persons,  (v) any  trustees  and retired  trustees of any
investment company for which 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 which has a dealer agreement with MFD,
by certain family members of any such employee or representative  and his or her
spouse or to any trust, pension, profit-sharing or other retirement plan for the
sole benefit of such employee or representative  and by clients of the MFS Asset
Management,  Inc.  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\s/\m/ 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\s/\m/ 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 after  purchase.  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.

GENERAL:  If shares of the Fund are made available for sale, 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
participation  in the  Automatic  Exchange  Plan are subject to a $50 minimum on
initial and additional  investments per account.  Any minimums may be changed at
any time at the discretion of MFD. The Fund reserves the right to cease offering
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.

ALTHOUGH  ALL MFS FUNDS ARE  GENERALLY  AVAILABLE  AS AN  INVESTMENT  CHOICE FOR
TAX-DEFERRED RETIREMENT PROGRAMS SUCH AS AN IRA OR A RETIREMENT PLAN (AS DEFINED
ABOVE),  MUNICIPAL  BOND  FUNDS,  SUCH  AS THE  FUND,  MAY NOT BE  SUITABLE  FOR
INCLUSION IN SUCH PROGRAMS DUE TO THEIR TAX-EXEMPT  NATURE.  THE MINIMUM INITIAL
INVESTMENT  FOR IRAS IS $250 AND THE MINIMUM  ADDITIONAL  INVESTMENT  IS $50 PER
ACCOUNT.  A  SHAREHOLDER  SHOULD  CONSULT  HIS OR HER  FINANCIAL  OR TAX ADVISER
REGARDING ANY SUCH INVESTMENT.

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 record-keeping
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
certin 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 and  Class B  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.  In
addition,  from time to time, MFD may pay dealers 100% of the  applicable  sales
charge on sales of Class A shares of  certain  specified  MFS Funds sold by such
dealer during a specified sales period. In addition,  MFD or its affiliates may,
from time to time,  pay dealers an additional  commission  equal to 0.50% of the
net asset value of all of the Class B shares of certain specified 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.  Other  concessions may be offered to the extent not
prohibited by the laws of the state or any self-regulatory agency, such as 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,  FSI believes that such Act should not
preclude  banks from  entering  into agency  agreements  with FSI (as  described
above).  If, however,  a bank were prohibited from so acting, the Trustees would
consider  what  actions,  if any,  would be  necessary  to  continue  to provide
efficient  and  effective   shareholder   services.  It  is  not  expected  that
shareholders would suffer any adverse financial consequence as a result of these
occurrences.  In addition,  state  securities laws on this issue may differ from
the  interpretation  of federal  law  expressed  herein and banks and  financial
institutions  may be required to  register as  broker-dealers  pursuant to state
law.

EXCHANGES
Subject to the  requirements  set forth  below,  some or all of the shares in an
account with the Fund for which payment has been received by the Fund (i.e.,  an
established account) may be exchanged for shares of the same class of any of the
other MFS Funds (if available for sale) at net asset value.  Shares of one class
may not be exchanged for shares of any other class.  Exchanges will be made only
after  instructions  in writing or by  telephone  (an  "Exchange  Request")  are
received for an established account by the Shareholder Servicing Agent in proper
form (i.e., if in writing -- signed by the record owner(s) exactly as the shares
are registered; if by telephone -- proper account identification is given by the
dealer or  shareholder  of record) and each exchange must involve  either shares
having an aggregate value of at least $1,000 ($50 in the case of retirement plan
participants  whose  sponsoring  organizations  subscribe to the MFS FUNDamental
401(k) Plan or another similar 401(k) recordkeeping system made available by the
Shareholder  Servicing  Agent) or all the shares in the account.  If an Exchange
Request is received by the Shareholder Servicing Agent on any business day prior
to the close of regular trading on the New York Stock Exchange (the "Exchange"),
the exchange  usually will occur on that day if all the  restrictions  set forth
above have been complied  with at that time. No more than five  exchanges may be
made in any one Exchange Request by telephone. Additional information concerning
this exchange  privilege and  prospectuses for any of the other MFS Funds may be
obtained  from  investment  dealers  or  the  Shareholder   Servicing  Agent.  A
shareholder  should read the  prospectus  of the other MFS Fund and consider the
differences in objectives and policies  before making any exchange.  For federal
and (generally)  state income tax purposes,  an exchange is treated as a sale of
the shares exchanged and, therefore,  an exchange could result in a gain or loss
to the shareholder making the exchange. Exchanges by telephone are automatically
available  to most  non-retirement  plan  accounts and certain  retirement  plan
accounts.   For  further  information   regarding  exchanges  by  telephone  see
"Redemptions By Telephone".  The exchange privilege (or any aspect of it) may be
changed or discontinued and is subject to certain limitations, including certain
restrictions on purchases by market timers.  Special procedures,  privileges and
restrictions with respect to exchanges may apply to market timers who enter into
an agreement with 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).  When a  shareholder  withdraws  an amount  from his  account,  the
shareholder  is deemed to have  tendered for  redemption a sufficient  number of
full and fractional shares in his account to cover the amount withdrawn. Certain
purchases,  however, may be subject to a CDSC in the event of certain redemption
transactions (see "Contingent Deferred Sales Charge" below). For the convenience
of shareholders,  the Fund has arranged for different  procedures for redemption
and  repurchase.  The proceeds of a redemption  or  repurchase  will normally be
available within seven days, except for shares purchased or received in exchange
for shares purchased by check (including  certified checks or cashier's checks);
payment  of  redemption  proceeds  may be  delayed  for up to 15 days  from  the
purchase  date in an effort to assure  that such check has  cleared.  Payment of
redemption  process 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  in "good  order"  by the  Shareholder
Servicing  Agent,  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 the Exchange is restricted or, to the extent  otherwise  permitted by
the 1940 Act, if an emergency exists (see "Tax Status").

B.  REDEMPTION  BY TELEPHONE -- Each  shareholder  may redeem an amount from his
account by telephoning the  Shareholder  Servicing Agent 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 BEFORE THE CLOSE OF
BUSINESS  ON THE SAME DAY,  THE  SHAREHOLDER  WILL  RECEIVE  THE NET ASSET VALUE
CALCULATED  ON THAT DAY,  REDUCED BY THE AMOUNT OF ANY  APPLICABLE  CDSC AND THE
AMOUNT OF ANY INCOME TAX REQUIRED TO BE WITHHELD.

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 securities
(instead of cash) from the Fund's portfolio.  The securities distributed in such
a  distribution  would be valued at the same amount as that  assigned to them in
calculating  the net asset  value for the shares  being sold.  If a  shareholder
receives a  distribution  in kind,  the  shareholder  could incur  brokerage  or
transaction charges in converting the securities to cash.

Due to the relatively high cost of maintaining small accounts, the Fund reserves
the right to redeem  shares in any account for their  then-current  value (which
will be promptly paid to the shareholder) if at any time the total investment in
such  account  drops below $500  because of  redemptions,  except in the case of
accounts  established  for monthly  automatic  investments  and certain  payroll
savings  programs  and the  Automatic  Exchange  Plan 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.

   
SIGNATURE  GUARANTEE:  In order to protect  shareholders  to the greatest extent
possible  against  fraud,  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.
    

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

Therefore,  at the time of redemption of shares of a particular  class,  (i) any
Free  Amount is not subject to the CDSC,  and (ii) the amount of the  redemption
equal to the then-current value of Reinvested Shares is not subject to the CDSC,
but  (iii) any  amount of the  redemption  in  excess  of the  aggregate  of the
then-current  value of  Reinvested  Shares  and the Free  Amount is subject to a
CDSC.  The CDSC will first be  applied  against  the amount of Direct  Purchases
which will result in any such charge being imposed at the lowest  possible rate.
The CDSC to be imposed  upon  redemptions  of shares 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 PLAN
    
The Trustees  have adopted a  distribution  plan for Class B shares  pursuant to
Section  12(b) of the 1940 Act and Rule  12b-1  thereunder  (the  "Rule")  after
having  concluded  that  there is a  reasonable  likelihood  that the plan would
benefit the Fund and the Class B shareholders. There is no distribution plan for
Class A shares.

   
    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 may
annually  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% per
annum of the  Fund's  average  daily net assets  attributable  to Class B shares
owned by investors  for whom that  securities  dealer is the holder or dealer of
record).  This service fee is intended to be  additional  consideration  for all
personal  services and/or account  maintenance  services  rendered by the dealer
with respect to Class B shares. Fees payable under the Class B Distribution Plan
are charged to, and therefore reduce, income allocated to Class B shares. Except
in the case of the first year  service  fee, no service  fee will be paid.  This
elimination  of the service fee may be amended or terminated  without  notice to
shareholders.  The first year service fee will be paid as noted below. The Class
B Distribution  Plan also provides that MFD will receive all CDSCs  attributable
to Class B  shares  which  do not  reduce  the  distribution  fee.  MFD will pay
commissions  to  dealers  of 3.75% of the  purchase  price of  shares  purchased
through dealers.  MFD will also advance to dealers the first year service fee at
a rate equal to 0.25% per annum 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 a 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  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.

DISTRIBUTIONS
The Fund intends to pay  substantially  all of its net investment  income to its
shareholders  as dividends on a monthly basis. In determining the net investment
income  available for  distributions,  the Fund may rely on  projections  of its
anticipated net investment income over a longer term, rather than its actual net
investment  income  for the  period in order to  provide  more  stable  periodic
distributions.  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 shares because expenses attributable to Class B shares will generally
be higher.

TAX STATUS
The Fund is treated as an entity separate from the other series of the Trust for
federal  income  tax  purposes.  In order to  minimize  the taxes the Fund would
otherwise  be  required  to pay,  the Fund  intends  to  qualify  each year as a
"regulated  investment  company"  under  Subchapter  M of the Code,  and to make
distributions  to its  shareholders in accordance  with the timing  requirements
imposed by the Code.  It is  expected  that the Fund will not be required to pay
any entity level  federal  income or excise  taxes.  Because the Fund intends to
satisfy  certain  requirements of the Code, the Fund expects to pay dividends to
shareholders  from interest on Municipal  Bonds that are  generally  exempt from
federal income tax. From time to time a portion of the Fund's distributions will
be taxable to shareholders  (e.g.,  distributions  of income from investments in
taxable securities, including repurchase agreements and income from transactions
in certain  Municipal Bonds  purchased at a market discount and  distribution of
capital gains realized by the Fund,  including gains recognized from options and
futures transactions,  whether paid in cash or reinvested in additional shares).
Depending  on  the  nature  of  the   distribution  and  the  residence  of  the
shareholder, certain Fund distributions may be subject to state and local income
taxes; shareholders should consult with their own tax advisors in this regard.

Shortly after the end of each calendar  year,  each  shareholder  will be sent a
statement  setting  forth  the  federal  income  status  of  all  dividends  and
distributions  for that year,  including any portion taxable as ordinary income,
the portion exempted from federal income tax as "exempt-interest dividends," any
portion that is a tax preference  item for purposes of the  alternative  minimum
tax,  any portion  taxable as long-term  capital  gains,  the  portion,  if any,
representing a return of capital (which is generally free of taxes,  but results
in a basis reduction), and the amount, if any, of federal income tax withheld.

Current federal tax law limits the types and volume of bonds  qualifying for the
federal  income  tax  exemption  of  interest  and  makes  interest  on  certain
tax-exempt bonds and distributions by the Fund of such interest a tax preference
item for purposes of the individual and corporate  alternative  minimum tax. All
exempt-interest  dividends  may  affect a  corporate  shareholder's  alternative
minimum tax liability.
    

Interest on indebtedness incurred by shareholders to purchase or carry shares of
the Fund  will not be  deductible  for  federal  income  tax  purposes.  Exempt-
interest  dividends are taken into account in  calculating  the amount of social
security and railroad  retirement benefits that may be subject to federal income
tax.  Entities or persons  who are  "substantial  users" (or persons  related to
"substantial  users") of facilities  financed by certain private  activity bonds
should  consult  their  tax  advisers  before  purchasing  shares  of the  Fund.
"Substantial  user" is defined generally as including a "non-exempt  person" who
regularly  uses in trade or  business  a part of a  facility  financed  from the
proceeds of certain private activity bonds.

   
Fund   distributions   will  reduce  the  Fund's  net  asset  value  per  share.
Shareholders who buy shares just before the Fund makes a distribution of taxable
income may thus pay the full price for the shares and then effectively receive a
portion of the purchase price back as a taxable distribution.

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

Prospective  investors should read the Fund's Account Application for additional
information  regarding  backup  withholding  of  federal  income  tax and should
consult  their  own  tax  advisers  as to the  tax  consequences  to  them of an
investment in the Fund.

NET ASSET VALUE
The net asset value per share of each class of shares of the Fund is  determined
each day during which the Exchange is open for trading.  This  determination  is
made  once  during  each  such day as of the  close of  regular  trading  on the
Exchange by deducting the amount of the  liabilities  attributable  to the class
from the value of the Fund's assets  attributable  to the class and dividing the
difference  by the  number of shares  of the  class  outstanding.  Assets in the
Fund's portfolio are valued on the basis of their market or other fair value, 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 business on that day.

DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES
The Fund,  one of two series of the Trust,  has two classes of shares,  entitled
Class A and Class B Shares of Beneficial Interest (without par value). The Trust
has  reserved  the right to create and issue  additional  classes  and series of
shares, in which case 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  ratification  of
selection of  accountants.  Additionally,  each class of shares of a series will
vote separately on any material  increases in the fees under its Rule 12b-1 plan
(in the case of Class B shares) or on any other matter that affects  solely that
class of shares,  but will  otherwise  vote  together  with all other classes of
shares of the  series on all other  matters.  The Trust  does not intend to hold
annual  shareholder  meetings.  The Declaration of Trust provides that a Trustee
may be removed from office in certain  instances  (see  "Description  of Shares,
Voting Rights and Liabilities" in the Statement of Additional Information).

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

    
The Trust is an entity of the type commonly known as a  "Massachusetts  business
trust". Under Massachusetts law, shareholders of such a trust may, under certain
circumstances,  be held  personally  liable  as  partners  for its  obligations.
However,  the risk of a  shareholder  incurring  financial  loss on  account  of
shareholder  liability  is limited  to  circumstances  in which both  inadequate
insurance existed (e.g., fidelity bonding and errors and omission insurance) and
the Trust itself was unable to meet its obligations.

   
PERFORMANCE INFORMATION
From time to time,  the Fund will  provide  yield,  current  distribution  rate,
tax-equivalent  yield 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. Any yield and tax-equivalent 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 twelve months and is
computed by dividing the amount of such dividends by the maximum public offering
price  of that  class  at the  end of such  period.  Current  distribution  rate
calculations for Class B shares assume no CDSC is paid. The current distribution
rate differs from the yield calculation because it may include  distributions to
shareholders  from sources other than  dividends  and interest,  such as premium
income from option  writing,  short-term  capital gains,  and return of invested
capital, and is calculated over a different period of time. Total rate of return
quotations  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 a CDSC,  and which  will thus be
higher. All performance  quotations are based on historical  performance and are
not intended to indicate  future  performance.  Yield and  tax-equivalent  yield
reflect only net portfolio  income  allocable to a class as of a stated 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,  tax-equivalent
yield and total rate of return, see the Statement of Additional Information. For
further  information  about the Fund's  performance  for the  fiscal  year ended
January 31,  1995,  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.
    


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

ACCOUNT  AND   CONFIRMATION   STATEMENTS  --  Each   shareholder   will  receive
confirmation  statements showing the transaction activity in his account. At the
end of each calendar year each  shareholder  will receive income tax information
regarding the tax status of all reportable  dividends and distributions for that
year.

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)  of  dividends  and  capital  gain
distributions  will be made in additional full and fractional shares of the same
class of  shares  of the Fund at the net  asset  value in effect at the close of
business on the record  date.  Dividends  and  capital  gains  distributions  in
amounts less than $10 will  automatically be reinvested in additional  shares of
the Fund. If a shareholder has elected to receive  dividends and/or capital gain
distributions  in cash and the  postal or other  delivery  service  is unable to
deliver  checks to the  shareholder's  address  of  record,  such  shareholder's
distribution  option will automatically be converted to having all dividends and
other  distributions  reinvested in additional shares. Any request for an option
change 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
Class B shares of the Fund or any of the classes of other MFS Funds or MFS Fixed
Fund within a 13-month period (or 36-month period for purchases of $1 million or
more),  the  shareholder  may obtain such shares of the Fund at the same reduced
sales charge as though the total quantity were invested in one lump sum, subject
to escrow agreements and the appointment of an attorney for redemptions from the
escrow amount if the intended  purchases are not  completed,  by completing  the
Letter of Intent section of the Account Application.

    RIGHT OF  ACCUMULATION:  A  shareholder  qualifies for  cumulative  quantity
discounts on purchases of Class A shares when his new investment,  together with
the current  offering  price  value of all  holdings of all classes of shares of
that shareholder in the MFS Funds or MFS Fixed Fund reaches a discount level.
    

    DISTRIBUTION  INVESTMENT  PROGRAM:  Shares of a particular class of the Fund
may be sold at net asset value (and  without any  applicable  CDSC)  through the
automatic  reinvestment of distributions of dividends and capital gains 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 any
other MFS Fund,  if shares of such  Fund are  available  for sale  (without  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  generally are 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 shares of the same class of
shares of the other MFS Funds under the  Automatic  Exchange Plan if such shares
are  available  for sale.  The  Automatic  Exchange  Plan provides for automatic
exchanges of funds from the shareholder's  account in an MFS Fund for investment
in the same  class of shares of other MFS  Funds  selected  by the  shareholder.
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 and 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 purchase  through  periods of low price
levels.  Maintaining  a  dollar  cost  averaging  program  concurrently  with  a
withdrawal  program  could  be  disadvantageous  because  of the  sales  charges
included in share purchases.

                         TAXABLE EQUIVALENT YIELD TABLE

                                                                     APPENDIX B
                         DESCRIPTION OF MUNICIPAL BONDS

    
    Municipal Bonds include debt obligations  issued to obtain funds for various
public purposes, including the construction of a wide range of public facilities
such as bridges,  highways,  housing,  hospitals, mass transportation,  schools,
streets and water and sewer  works.  Other public  purposes for which  Municipal
Bonds may be issued include refunding outstanding  obligations,  obtaining funds
for general  operating  expenses,  and  obtaining  funds to loan to other public
institutions   and  facilities.   In  addition,   certain  types  of  industrial
development  bonds are  issued by or on behalf of public  authorities  to obtain
funds to  provide  privately-operated  housing  facilities,  sports  facilities,
convention or trade show  facilities,  airport,  mass  transit,  port or parking
facilities,  air  or  water  pollution  control  facilities  and  certain  local
facilities for water supply, gas, electricity or sewage or solid waste disposal.
Such  obligations  are included  within the term Municipal Bonds if the interest
paid  thereon  qualifies  as exempt from federal  income  taxes.  Other types of
industrial   development   bonds,  the  proceeds  of  which  are  used  for  the
construction,  equipment, repair or improvement of privately operated industrial
or commercial  facilities,  may constitute Municipal Bonds, although the current
federal tax laws place substantial limitations on the size of such issues.

    The  two  principal   classifications   of  Municipal   Bonds  are  "general
obligation" and "revenue"  bonds.  General  obligation  bonds are secured by the
issuer's  pledge of its good faith,  credit and taxing  power for the payment of
principal  and  interest.  The  payment of such bonds may be  dependent  upon an
appropriation  by  the  issuer's   legislative  body.  The  characteristics  and
enforcement of general  obligation bonds vary according to the law applicable to
the particular issuer.  Revenue bonds are payable only from the revenues derived
from a particular  facility or class of facilities  or, in some cases,  from the
proceeds  of a  special  excise or other  specific  revenue  source.  Industrial
development  bonds which are Municipal Bonds are in most cases revenue bonds and
do not  generally  constitute  the  pledge of the  credit of the  issuer of such
bonds.  Municipal Bonds also include  participations in municipal leases.  These
are undivided  interests in a portion of an obligation in the form of a lease or
installment  purchase which is issued by state and local  governments to acquire
equipment and  facilities.  Municipal  leases  frequently have special risks not
normally  associated  with  general  obligation  or  revenue  bonds.  Leases and
installment  purchase or conditional  sale contracts (which normally provide for
title to the leased asset to pass  eventually to the  governmental  issuer) have
evolved as a means for  governmental  issuers to acquire  property and equipment
without meeting the constitutional  and statutory  requirements for the issuance
of debt. The debt-issuance  limitations are deemed to be inapplicable because of
the  inclusion in many leases or contracts of  "non-appropriation"  clauses that
provide that the  governmental  issuer has no obligation to make future payments
under the lease or contract unless money is appropriated for such purpose by the
appropriate  legislative body on a yearly or other periodic basis.  Although the
obligations  will  be  secured  by  the  leased  equipment  or  facilities,  the
disposition  of the  underlying  property in the event of  non-appropriation  or
foreclosure might, in some cases,  prove difficult.  In light of these concerns,
the  staff of the SEC has  advised  investment  companies  to adopt  and  follow
procedures for  determining  whether  municipal lease  securities  purchased are
liquid and for monitoring the liquidity of municipal  lease  securities  held in
such company's portfolio.  The Board of Trustees has adopted such procedures and
has  delegated  to the  Adviser  the  authority  to make  determinations  on the
liquidity of municipal lease  securities in accordance with the procedures.  The
procedures  require that the Adviser use a number of factors in calculating  the
liquidity of a municipal lease security,  including, the frequency of trades and
quotes for the security,  the number of dealers  willing to purchase or sell the
security  and the  number of other  potential  purchasers,  the  willingness  of
dealers  to  undertake  to make a market  in the  security,  the  nature  of the
marketplace in which the security trades, the credit quality of the security and
other  factors  which the  Adviser  may deem  relevant.  There  are,  of course,
variations  in the  security  of  Municipal  Bonds,  both  within  a  particular
classification and between classifications, depending on numerous factors.

    The  yields on  Municipal  Bonds are  dependent  on a  variety  of  factors,
including  general  money  market  conditions,  supply and  demand  and  general
conditions  of the Municipal  Bond market,  size of a particular  offering,  the
maturity of the obligation and rating of the issue.

                     DESCRIPTION OF MUNICIPAL BOND RATINGS

   
    The ratings of Moody's,  S&P and Fitch  represent  their  opinions as to the
quality of various debt instruments.
    

                        MOODY'S INVESTORS SERVICE, INC.

Aaa: Bonds which are rated Aaa are judged to be of the best quality.  They carry
the smallest  degree of investment  risk and are generally  referred to as "gilt
edge." 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 in Aaa securities.

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

Con. (...): Bonds for which the security depends upon the completion of some act
or the  fulfillment of some condition are rated  conditionally.  These are bonds
secured by (a) earnings of projects under construction, (b) earnings of projects
unseasoned in operation experience,  (c) rentals which begin when facilities are
completed,  or (d)  payments to which some other  limiting  condition  attaches.
Parenthetical   rating  denotes  probable  credit  stature  upon  completion  of
construction or elimination of basis of condition.

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  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:  Those bonds in the Aa, A, Baa,  Ba and B groups  which  Moody's  believes
possess the strongest  investment  attributes are designated by the symbols Aa1,
A1, Baa1, Ba1 and B1.

                        STANDARD & POOR'S RATINGS GROUP

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 very  strong  capacity  to pay  interest  and repay
principal and differ 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  catgegory  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: Bonds 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 payment is jeopardized.

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

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 INVESTORS SERVICE, INC.

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  foreseeble   future
developments, short-term debt of these issuers is generally rated "F-1+".

A: Bonds  considered  to be  investment  grade and of 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 wih 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 of
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 protected. Default in payment of interest and/or
principal seems probable over time.

C: Bonds are in immiment 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.

NR 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 indadequate 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 raised
or lowered.  FitchAlert is relatively short-term,  and should be resolved within
12 months.

1.  DEFINITIONS
   "Fund"
                                 --  MFS(R) Municipal High Income Fund, a series
                                     of MFS Series  Trust III (the  "Trust"),  a
                                     Massachusetts business trust. The Trust was
                                     previously known as Massachusetts Financial
                                     High  Income   Trust  until  its  name  was
                                     changed on August 20, 1993. The Fund is the
                                     successor to MFS High Yield  Municipal Bond
                                     Fund which was  reorganized  as a series of
                                     the Trust on September 7, 1993.

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

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

   "Prospectus"                  --  The Prospectus,  dated June 1, 1995, of the
                                     Fund.

2.  INVESTMENT OBJECTIVE, POLICIES AND RESTRICTIONS
INVESTMENT  OBJECTIVE.  The investment  objective of the Fund is to provide high
current  income exempt from federal income taxes.  Any investment  involves risk
and  there  can be no  assurance  that  the Fund  will  achieve  its  investment
objective.

INVESTMENT  POLICIES.  The Fund seeks to achieve  its  investment  objective  by
investing   primarily   (i.e.,   at  least  80%  of  its  assets   under  normal
circumstances) in debt securities issued by or on behalf of states,  territories
and  possessions  of the United  States,  the  District of  Columbia,  and their
political subdivisions, agencies or instrumentalities,  the interest on which is
exempt from federal income tax ("Municipal  Bonds" or "tax-exempt  securities").
Under  normal  circumstances,  the Fund  will  invest  at least 65% of its total
assets in tax-exempt securities which offer a current yield above that generally
available on tax-exempt securities in the three highest rating categories of the
recognized  rating  agencies  (commonly known as "junk bonds" if rated below the
four  highest  categories  of  recognized  rating  agencies).   Such  high  risk
securities  generally  involve  greater  volatility of price and greater risk of
nonpayment of principal and interest (including the possibility of default by or
bankruptcy of the issuers of such  securities)  than securities in higher rating
categories.  However,  since available yields and yield  differentials vary over
time,  no specific  level of income or yield  differential  can ever be assured.
Also, any income earned on portfolio  securities  would be reduced by the Fund's
expenses before it is distributed to shareholders.

The Fund may invest in a relatively high percentage of municipal bonds issued by
entities having similar characteristics.  The issuers may be located in the same
geographic  area, or may pay their interest  obligations from revenue of similar
projects such as hospitals,  electric  utility  systems,  multi-family  housing,
nursing homes, commercial facilities (including hotels), steel companies or life
care facilities.  This may make the Fund more  susceptible to similar  economic,
political,  or regulatory  occurrences.  As the similarity in issuers increases,
the potential for  fluctuation of the net asset value of shares of the Fund also
increases.

The Fund  reserves the right to invest more than 25% of its assets in industrial
revenue  bonds such as  industrial  revenue  bonds issued for  electric  utility
systems,  multi-family  housing,  health care  facilities,  and steel companies.
Industrial  revenue  bonds are issued by  various  state and local  agencies  to
finance  various  projects.  These  investments  might entail risks as described
below.

Electric utility systems face problems in financing large construction  programs
in an inflationary  period, cost increases and delay occasioned by environmental
considerations (particularly with respect to nuclear facilities),  difficulty in
obtaining  fuel at  reasonable  prices,  the  cost of  competing  fuel  sources,
difficulty in obtaining sufficient rate increases and other regulatory problems,
the effect of energy conservation and difficulty of the capital market to absorb
utility debt.

The  financing  of  multi-family  housing  projects  is affected by a variety of
factors,   including   satisfactory   completion  of  construction  within  cost
constraints, the achievement and maintenance of a sufficient level of occupancy,
sound management of the developments,  timely and adequate increases in rents to
cover  increases in  operating  expenses,  including  taxes,  utility  rates and
maintenance costs,  changes in applicable laws and governmental  regulations and
social and economic trends.

Healthcare facilities include lifecare facilities,  nursing homes and hospitals.
Lifecare facilities and nursing homes are alternative forms of long-term housing
for the elderly which offer residents the independence of condominium life style
and,  if needed,  the  comprehensive  care of nursing  home  services.  Bonds to
finance  lifecare  facilities  have been  issued  by  various  state  industrial
development  authorities.  Since the bonds are secured  only by the  revenues of
each  facility  and not by state  or local  government  tax  payments,  they are
subject to a wide  variety  of risks.  Primarily,  the  projects  must  maintain
adequate  occupancy levels to be able to provide  revenues  adequate to maintain
debt service payments.  Moreover,  in the case of life care facilities,  since a
portion of  housing,  medical  care and other  services  may be  financed  by an
initial  deposit,  there may be risk if the facility does not maintain  adequate
financial  reserves to secure estimated  actuarial  liabilities.  The ability of
management to forecast inflationary cost pressures accurately weighs importantly
in this  process.  The  facilities  may  also be  impacted  by  regulatory  cost
restrictions  applied to health care  delivery in  general,  particularly  state
regulations or changes in Medicare and Medicaid payments or  qualifications,  or
restrictions  imposed  by  medical  insurance  companies.  They  may  also  face
competition from alternative  health care or conventional  housing facilities in
the  private  or  public  sector.  Hospital  bond  ratings  are  often  based on
feasibility  studies  which  contain  projections  of  expenses,   revenues  and
occupancy  levels.  A  hospital's  gross  receipts  and net income  available to
service its debt are influenced by demand for hospital services,  the ability of
the  hospital  to  provide  the  services   required,   management  and  medical
capabilities, economic developments in the service area, efforts by insurers and
government  agencies to limit rates and  expenses,  confidence  in the hospital,
service area economic  developments,  competition,  availability  and expense of
malpractice  insurance,  Medicaid and  Medicare  funding,  and possible  federal
legislation limiting the rates of increase of hospital charges.

The Fund may also  invest in bonds for other  commercial  facilities  (including
hotels) and industrial projects.  Financing for such projects will be subject to
inflation  and other  general  economic  factors as well as  construction  risks
including labor problems,  difficulties with construction  sites and the ability
of contractors to meet specifications in a timely manner.

If a revenue  bond is  secured by  payments  generated  from a project,  and the
revenue  bond is  also  secured  by a lien on the  real  estate  comprising  the
project, foreclosure by the indenture trustee on the lien for the benefit of the
bondholders  creates  additional  risks  associated  with  owning  real  estate,
including environmental risks.

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

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

LOANS AND  OTHER  DIRECT  INDEBTEDNESS:  The Fund may  purchase  loans and other
direct claims against a borrower. In purchasing loans, 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, although some may be unsecured.
Such  loans may be in  default  at the time of  purchase.  Loans  that are fully
secured offer the Fund more  protection  than an unsecured  loan in the event of
non-payment of scheduled interest or principal.  However,  there is no assurance
that the  liquidation  of  collateral  from a secured  loan  would  satisfy  the
corporate borrower's obligation, or that the collateral can be liquidated.

These  loans  are  made   generally  to  finance   internal   growth,   mergers,
acquisitions,   stock  repurchases,   leveraged  buy-outs  and  other  corporate
activities.   Such  loans  are   typically   made  by  a  syndicate  of  lending
institutions,  represented by an agent lending  institution which has negotiated
and structured the loan and is responsible  for collecting  interest,  principal
and other  amounts  due on its own  behalf  and on  behalf of the  others in the
syndicate,  and for enforcing  its and their other rights  against the borrower.
Alternatively, such loans may be structured as a novation, pursuant to which the
Fund would assume all of the rights of the lending  institution in a loan, or as
an  assignment,  pursuant to which the Fund would  purchase an  assignment  of a
portion of a lender's  interest  in a loan  either  directly  from the lender or
through  an  intermediary.  The  Fund may also  purchase  trade or other  claims
against  companies,  which  generally  represent  money 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  loans  acquired  by  the  Fund  may  involve  revolving  credit
facilities or other standby financing commitments which obligate the Fund to pay
additional cash on a certain date or on demand.  These  commitments may have the
effect of requiring  the Fund to increase its  investment in a company at a time
when the Fund might not otherwise  decide to do so (including at a time when the
company's  financial  condition  makes it  unlikely  that such  amounts  will be
repaid).  To the extent that the Fund is committed to advance  additional funds,
it will at all times hold and  maintain in a  segregated  account  cash or other
high grade debt obligations in an amount sufficient to meet such commitments.

The Fund's ability to receive payments of principal,  interest and other amounts
due in connection with these  investments will depend primarily on the financial
condition of the borrower.  In selecting the loans and other direct  investments
which the Fund will  purchase,  the Adviser  will rely upon its (and not that of
the original lending  institution's) own credit analysis of the borrower. As the
Fund may be required to rely upon  another  lending  institution  to collect and
pass on to the Fund amounts  payable with respect to the loan and to enforce the
Fund's rights under the loan, an insolvency, bankruptcy or reorganization of the
lending  institution  may delay or prevent the Fund from receiving such amounts.
In such  cases,  the Fund  will  evaluate  as well the  creditworthiness  of the
lending institution and will treat both the borrower and the lending institution
as an "issuer"  of the loans for  purposes  of certain  investment  restrictions
pertaining  to the  diversification  of the Fund's  portfolio  investments.  The
highly  leveraged  nature of many such  loans  may make  such  loans  especially
vulnerable to adverse changes in economic or market  conditions.  Investments in
such loans may involve  additional risks to the Fund. For example,  if a loan is
foreclosed,  the Fund could become part owner of any collateral,  and would bear
the  costs  and  liabilities   associated  with  owning  and  disposing  of  the
collateral. In addition, it is conceivable that under emerging legal theories of
lender  liability,  the Fund could be held liable as a co-lender.  It is unclear
whether  loans  and other  forms of direct  indebtedness  offer  securities  law
protections  against fraud and  misrepresentation.  In the absence of definitive
regulatory guidance,  the Fund relies on the Adviser's research in an attempt to
avoid  situations  where fraud or  misrepresentation  could adversely affect the
Fund. In addition,  loans 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.  To the extent that the Adviser  determines that
any such investments are illiquid,  the Fund will include them in the investment
limitations described below.

"WHEN-ISSUED" SECURITIES: The Fund may purchase securities on a "when-issued" or
on a "forward delivery" basis. When the Fund commits to purchase a security on a
"when-issued" or "forward delivery" basis, it will set up procedures  consistent
with the General  Statement of Policy of the Securities and Exchange  Commission
(the "SEC")  concerning such purchases.  Since that policy currently  recommends
that an amount of the Fund's  assets equal to the amount of the purchase be held
aside or segregated to be used to pay for the  commitment,  the Fund will always
have cash, cash equivalents or high quality debt securities  sufficient to cover
any commitments or to limit any potential risk. However,  although the Fund does
not intend to make such purchases for speculative purposes and intends to adhere
to the  provisions of the SEC policy,  purchases of securities on such bases may
involve more risk than other types of purchases.  For example, the Fund may have
to sell assets which have been set aside in order to meet redemptions.  Also, if
the Fund  determines  it is  necessary  to sell the  "when-issued"  or  "forward
delivery"  securities  before  delivery,  it may incur a loss  because of market
fluctuations  since the time the commitment to purchase such securities was made
and any gain or loss would not be tax-exempt.

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

INDEXED SECURITIES: The Fund may purchase securities whose prices are indexed to
the prices of other  securities,  securities  indices,  precious metals or other
commodities,  or other financial indicators.  Indexed securities typically,  but
not always,  are debt  securities or deposits  whose value at maturity or coupon
rate  is  determined  by  reference  to  a  specific  instrument  or  statistic.
Gold-indexed  securities,  for example,  typically  provide for a maturity value
that depends on the price of gold,  resulting in a security whose price tends to
rise and fall together with gold prices.

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

OPTIONS: The Fund intends to write covered put and call options and purchase put
and call options on fixed income  securities that are traded on U.S.  securities
exchanges and over-the-counter. Call options written by the Fund give the holder
the right to buy the  underlying  securities  from the Fund at a fixed  exercise
price;  put  options  written  by the Fund give the holder the right to sell the
underlying  securities  to the Fund at a fixed  exercise  price.  A call  option
written  by the Fund is  "covered"  if the Fund  owns  the  underlying  security
covered by the call or has an  absolute  and  immediate  right to  acquire  that
security  without   additional  cash   consideration  (or  for  additional  cash
consideration  held in a segregated account by its custodian) upon conversion or
exchange  of other  securities  held in its  portfolio.  A call  option  is also
covered if the Fund holds a call on the same security and in the same  principal
amount  as the call  written  where the  exercise  price of the call held (a) is
equal to or less than the  exercise  price of the call written or (b) is greater
than the exercise  price of the call written if the  difference is maintained by
the Fund in cash or securities in a segregated account with its custodian. A put
option written by the Fund is "covered" if the Fund maintains cash or short-term
money  market  instruments  with a  value  equal  to  the  exercise  price  in a
segregated account with its custodian,  or else holds a put on the same security
and in the same principal  amount as the put written where the exercise price of
the put held is equal to or greater than the  exercise  price of the put written
or is less than the  exercise  price of the put  written  if the  difference  is
maintained  by the Fund in cash or  short-term  money  market  instruments  in a
segregated account with its custodian.  Put and call options written by the Fund
may also be  covered  in such  other  manner  as may be in  accordance  with the
requirements  of the  exchange on which,  or the counter  party with which,  the
option is traded,  and applicable laws and regulations.  The writer of an option
may have no control over when the  underlying  securities  must be sold,  in the
case of a call option,  or  purchased,  in the case of a put option,  since with
regard to certain options,  the writer may be assigned an exercise notice at any
time prior to the expiration of the option.

Effecting a closing transaction in the case of a written call option will permit
the Fund to write another call option on the  underlying  security with either a
different exercise price or expiration date or both, or in the case of a written
put option will  permit the Fund to write  another put option to the extent that
the exercise  price  thereof is secured by deposited  cash or  short-term  money
market  instruments.  Such transactions  permit the Fund to generate  additional
premium income,  which will partially  offset declines in the value of portfolio
securities  or  increases  in the  cost  of  securities  to be  acquired.  Also,
effecting  a closing  transaction  will  permit  the cash or  proceeds  from the
concurrent  sale of any  securities  subject  to the option to be used for other
Fund  investments.  If the Fund desires to sell a particular  security  from its
portfolio  on which it has  written  a call  option,  it will  effect a  closing
transaction prior to or concurrent with the sale of the security.

The Fund will  realize a profit from a closing  transaction  if the price of the
transaction is less than the premium received from writing the option or is more
than the premium paid to purchase the option;  the Fund will realize a loss from
a closing  transaction if the price of the  transaction is more than the premium
received  from  writing the option or is less than the premium  paid to purchase
the  option.  Because  increases  in the  market  price  of a call  option  will
generally reflect increases in the market price of the underlying security,  any
loss  resulting  from the closing out of a call option is likely to be offset in
whole or in part by appreciation of the underlying security owned by the Fund.

An option position may be closed out only where there exists a secondary  market
for an option of the same series. If a secondary market does not exist, it might
not be possible to effect closing  transactions  in particular  options with the
result  that the Fund  would  have to  exercise  options  purchased  in order to
realize any profit or maintain options written until exercise or expiration.  If
the Fund is  unable  to effect a closing  purchase  transaction  in a  secondary
market,  it will not be able to sell the  underlying  security  until the option
expires or it delivers the underlying  security upon  exercise.  Reasons for the
absence of a liquid  secondary  market include the  following:  (i) there may be
insufficient  trading  interest in certain  options;  (ii)  restrictions  may be
imposed by a national  securities  exchange on opening  transactions  or closing
transactions or both; (iii) trading halts, suspensions or other restrictions may
be imposed with respect to particular classes or series of options or underlying
securities;  (iv)  unusual or  unforeseen  circumstances  may  interrupt  normal
operations  on an  exchange;  (v) the  facilities  of an exchange or the Options
Clearing  Corporation  (the  "OCC") may not at all times be  adequate  to handle
current trading  volume;  or (vi) one or more exchanges  could,  for economic or
other  reasons,  decide or be compelled at some future date to  discontinue  the
trading of options (or a particular class or series of options),  in which event
the  secondary  market on that  exchange (or in that class or series of options)
would cease to exist,  although  outstanding  options on that  exchange that had
been issued by the OCC as a result of trades on that exchange  would continue to
be exercisable in accordance with their terms.

The Fund may write options in connection with buy-and-write  transactions (i.e.,
the Fund may  purchase a  security  and then write a call  option  against  that
security).  The  exercise  price of the call the Fund  determines  to write will
depend upon the expected price movement of the underlying security. The exercise
price of a call option may be below ("in-the-money"), equal to  ("at-the-money")
or above  ("out-of-the-money")  the current value of the underlying  security at
the time the  option is  written.  If the call  options  are  exercised  in such
transactions,  the Fund's  maximum  gain will be the premium  received by it for
writing the option,  adjusted upwards or downwards by the difference between the
Fund's purchase price of the security and the exercise price. If the options are
not exercised and the price of the underlying  security declines,  the amount of
such decline will be offset in part, or entirely, by the premium received.

The  writing  of  covered  put  options  is  similar  in  terms  of  risk/return
characteristics  to buy-and-write  transactions.  Put options may be used by the
Fund in the same market  environments  that call options are used in  equivalent
buy-and-write transactions.

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

The Fund may purchase put options to hedge against a decline in the value of its
portfolio.  By using put options in this way, the Fund will reduce any profit it
might  otherwise have realized in the  underlying  security by the amount of the
premium paid for the put option and by transaction costs.

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

The Fund may also purchase warrants on fixed income  securities.  A warrant on a
fixed income  security is a long-dated call option that provides the holder with
the right,  but not the  obligation,  to purchase  from an issuer a fixed income
security with a specified par value,  coupon,  and maturity at a fixed  exercise
price on a  specified  date or between  specified  dates.  Typically,  the fixed
income  securities  that  are  deliverable  pursuant  to  the  warrant  will  be
noncallable  securities.  Warrants may be issued as entirely separate securities
or they may be attached  to, but  subsequently  detachable  from, a fixed income
security of the same issuer.

The staff of the SEC has  taken the  position  that  purchased  over-the-counter
options and assets used to cover written  over-the-counter  options are illiquid
and, therefore, together with other illiquid securities, cannot exceed a certain
percentage (the "SEC  illiquidity  ceiling") of the Fund's assets.  Although the
Adviser  disagrees with this position,  the Adviser  intends to limit the Fund's
writing of over-the-counter  options in accordance with the following procedure.
Except as provided  below,  the Fund intends to write  over-the-counter  options
only with primary U.S.  Government  securities dealers recognized by the Federal
Reserve Bank of New York.  Also, the contracts  which the Fund has in place with
such  primary  dealers  will  provide  that the Fund has the  absolute  right to
repurchase an option it writes at any time at a price which  represents the fair
market  value,  as  determined  in good faith  through  negotiation  between the
parties,  but which in no event will  exceed a price  determined  pursuant  to a
formula  in the  contract.  Although  the  specific  formula  may  vary  between
contracts with different primary dealers, the formula will generally be based on
a multiple of the premium received by the Fund for writing the option,  plus the
amount,  if any, of the  option's  intrinsic  value  (i.e.,  the amount that the
option is  in-the-money).  The formula may also  include a factor to account for
the  difference  between the price of the  security  and the strike price of the
option if the option is written out-of-the-money.   The Fund will treat all or a
portion of the formula  price as illiquid  for  purposes of the SEC  illiquidity
ceiling  imposed  by the SEC  staff.  The Fund may also  write  over-the-counter
options with  non-primary  dealers and will treat the assets used to cover these
options as illiquid for purposes of such SEC illiquidity ceiling.

The Fund may purchase detachable call options on municipal securities, which are
options issued by an issuer of the underlying  municipal  securities  giving the
purchaser the right to purchase the securities at a fixed price,  up to a stated
time in the future or, in some cases,  on a future  date.  The Fund may purchase
detachable call options either in connection with its purchase of the underlying
municipal securities or in separate  transactions  unrelated to purchases of the
underlying  municipal  securities.  In  general,  however,  the Fund  will  only
purchase  detachable  call  options  that are  issued  at the  same  time as the
underlying municipal securities. The Fund may or may not purchase the underlying
municipal  securities.   Because  detachable  call  options  may  be  long  term
instruments, their value could be subject to greater volatility and, if the Fund
seeks to sell an option it has  purchased,  it could  sustain a loss of all or a
portion of the amount paid to purchase the option.  In this  regard,  detachable
call  options  have  only  recently  been  introduced  and  there  is not yet an
established market for the sale of such instruments.  In addition,  depending on
changes  in the  value  of the  underlying  municipal  security,  it may  not be
profitable for the Fund to exercise an option it has  purchased.  In that event,
the Fund will lose the amount of the purchase price paid for the option.

FUTURES  CONTRACTS:  The Fund may enter into  contracts for the purchase or sale
for future  delivery of fixed income  securities or contracts based on municipal
bond or other financial indices, including any index of fixed income securities,
as such contracts become available for trading ("Futures  Contracts").  A "sale"
of a Futures  Contract means a contractual  obligation to deliver the securities
called for by the contract at a specified price in a fixed delivery month or, in
the case of a Futures  Contract on an index of securities,  to make or receive a
cash  settlement.  A  "purchase"  of a  Futures  Contract  means  a  contractual
obligation to acquire the  securities  called for by the contract at a specified
price in a fixed  delivery  month or, in the case of a  Futures  Contract  on an
index of securities,  to make or receive a cash  settlement.  Futures  Contracts
have been designed by exchanges which have been designated as "contract markets"
by the Commodity Futures Trading  Commission (the "CFTC"),  and must be executed
through a futures commission  merchant,  or brokerage firm, which is a member of
the relevant  contract  market.  Existing  contract  markets include the Chicago
Board of Trade and the International  Monetary Market of the Chicago  Mercantile
Exchange.  Futures  Contracts are traded on these  markets,  and,  through their
clearing  corporations,  the exchanges guarantee performance of the contracts as
between the clearing members of the exchange.

At the same time a Futures Contract is purchased or sold, the Fund must allocate
cash or securities as a deposit payment ("initial deposit"). The initial deposit
varies  but may be as low as 5% or  less of the  value  of the  contract.  Daily
thereafter, the Futures Contract is valued and the payment of "variation margin"
may be  required  since  each day the Fund would  provide  or receive  cash that
reflects any decline or increase in the contract's value.

At the time of delivery of securities  pursuant to a Futures  Contract  based on
fixed income securities,  adjustments are made to recognize differences in value
arising from the delivery of securities with a different interest rate from that
specified in the contract.  In some (but not many) cases,  securities called for
by a Futures Contract may not have been issued when the contract was written.

A Futures  Contract  based on an index of  securities,  such as a municipal bond
index Futures  Contract,  provides for a cash payment,  equal to the amount,  if
any,  by which the value of the index at maturity is above or below the value of
the  index  at the time the  contract  was  entered  into,  times a fixed  index
"multiplier".  The index underlying such a Futures Contract is generally a broad
based index of securities  designed to reflect  movements in the relevant market
as a whole. The index assigns weighted values to the securities  included in the
index, and its composition is changed periodically.

Although Futures Contracts call for the actual delivery of securities or, in the
case of Futures  Contracts based on an index, the making or acceptance of a cash
settlement at a specified  future time,  the  contractual  obligation is usually
fulfilled  before  such  date by  buying  or  selling,  as the case may be, on a
commodities  exchange,  an identical  Futures Contract calling for settlement in
the same month,  subject to the availability of a liquid secondary  market.  The
Fund incurs brokerage fees when it purchases and sells Futures Contracts.

The  purpose of the  purchase  or sale of a Futures  Contract  entered  into for
hedging  purposes,  in the case of a portfolio  such as that of the Fund,  which
holds or intends to acquire long-term fixed income securities,  is to attempt to
protect the Fund from  fluctuations in interest rates without actually buying or
selling  long-term  fixed  income  securities.  For  example,  if the Fund  owns
long-term  bonds,  and interest rates were expected to increase,  the Fund might
enter into Futures Contracts for the sale of debt securities.  Such a sale would
have much the same effect as selling an equivalent  value of the long-term bonds
owned by the  Fund.  If  interest  rates  did  increase,  the  value of the debt
securities  in the  portfolio  would  decline,  but  the  value  of the  Futures
Contracts would increase at approximately the same rate, thereby keeping the net
asset value of the Fund from  declining as much as it otherwise  would have. The
Fund could accomplish  similar results by selling bonds with long maturities and
investing in bonds with short  maturities  when  interest  rates are expected to
increase.  However,  the use of Futures  Contracts  as an  investment  technique
allows  the Fund to  maintain  a  hedging  position  without  having to sell its
portfolio securities.

Similarly,  when  it is  expected  that  interest  rates  may  decline,  Futures
Contracts may be purchased to attempt to hedge against anticipated  purchases of
long-term bonds at higher prices. Since the fluctuations in the value of Futures
Contracts  should be similar  to that of  long-term  bonds,  the Fund could take
advantage  of the  anticipated  rise in the  value of  long-term  bonds  without
actually buying them until the market had stabilized.  At that time, the Futures
Contracts could be liquidated and the Fund could then buy long-term bonds on the
cash  market.  To the extent the Fund enters  into  Futures  Contracts  for this
purpose,  the assets in the  segregated  asset  account  maintained to cover the
Fund's  obligations with respect to such Futures Contracts will consist of cash,
cash equivalents or short-term money market instruments from its portfolio in an
amount  equal to the  difference  between the  fluctuating  market value of such
Futures  Contracts and the aggregate  value of the initial and variation  margin
payments made by the Fund with respect to such Futures Contracts.

The ordinary  spreads  between  prices in the cash and futures  markets,  due to
differences in the natures of those markets, are subject to distortions.  First,
all  participants  in the  futures  market are  subject to initial  deposit  and
variation margin  requirements.  Rather than meeting additional variation margin
requirements,  investors  may close out  Futures  Contracts  through  offsetting
transactions  which could distort the normal  relationship  between the cash and
futures  markets.  Second,  the  liquidity  of the  futures  market  depends  on
participants entering into offsetting  transactions rather than making or taking
delivery. To the extent participants decide to make or take delivery,  liquidity
in the futures market could be reduced, thus producing  distortion.  Third, from
the point of view of speculators, the margin deposit requirements in the futures
market are less  onerous  than margin  requirements  in the  securities  market.
Therefore,  increased  participation  by  speculators  in the futures market may
cause  temporary  price  distortions.  Due to the  possibility of distortion,  a
correct  forecast of general  interest  rate trends by the Adviser may still not
result in a successful transaction.

In addition, Futures Contracts entail risks. Although the Fund believes that use
of such  contracts will benefit the Fund, if the Adviser's  investment  judgment
about the general  direction of interest rates is incorrect,  the Fund's overall
performance  would be poorer than if it had not entered into any such  contract.
For example,  if the Fund has hedged  against the  possibility of an increase in
interest  rates  which  would  adversely  affect  the price of bonds held in its
portfolio and interest rates decrease instead, the Fund will lose part or all of
the benefit of the increased  value of its bonds which it has hedged  because it
will have  offsetting  losses in its futures  positions.  In  addition,  in such
situations,  if the Fund has  insufficient  cash, it may have to sell bonds from
its portfolio to meet daily variation margin  requirements.  Such sales of bonds
may be, but will not  necessarily  be, at  increased  prices  which  reflect the
rising  market.  The Fund may have to sell  securities  at a time when it may be
disadvantageous  to do so. The Fund may also enter into  transactions in Futures
Contracts for non-hedging  purposes,  to the extent permitted by applicable law,
which involves greater risks.

OPTIONS ON FUTURES CONTRACTS: The Fund may purchase and write options on Futures
Contracts  ("Options  on  Futures  Contracts")  for  hedging  purposes  and  for
non-hedging  purposes, to the extent permitted by applicable law. An Option on a
Futures  Contract  provides  the  holder  with the right to enter  into a "long"
position in the underlying Futures Contract,  in the case of a call option, or a
"short"  position  in the  underlying  Futures  Contract,  in the  case of a put
option, at a fixed exercise price up to a stated expiration date or, in the case
of certain  options,  on such date.  Such Options on Futures  Contracts  will be
traded on contract  markets  regulated by the CFTC.  Depending on the pricing of
the option compared to either the price of the Futures Contract upon which it is
based or the price of the underlying debt securities,  it may or may not be less
risky than ownership of the Futures Contract or underlying debt  securities.  As
with the purchase of Futures Contracts,  when the Fund is not fully invested, it
may  purchase  a call  Option on a Futures  Contract  to hedge  against a market
advance due to declining interest rates.

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

The Fund may cover the writing of call Options on Futures  Contracts (a) through
purchases  of the  underlying  Futures  Contract,  (b) through  ownership of the
security, or securities included in the index,  underlying the Futures Contract,
or (c)  through the holding of a call on the same  Futures  Contract  and in the
same  principal  amount as the call written where the exercise price of the call
held (i) is equal to or less than the exercise price of the call written or (ii)
is greater than the  exercise  price of the call  written if the  difference  is
maintained by the Fund in cash or  securities  in a segregated  account with its
custodian.  The Fund may cover the writing of put  Options on Futures  Contracts
(a) through sales of the underlying Futures Contract, (b) through segregation of
cash or  securities  in an amount  equal to the value of the  security  or index
underlying the Futures Contract, or (c) through the holding of a put on the same
Futures  Contract and in the same principal  amount as the put written where the
exercise price of the put held is equal to or greater than the exercise price of
the put  written or is less than the  exercise  price of the put  written if the
difference  is  maintained  by the Fund in cash or  securities  in a  segregated
account with its custodian. Put and call Options on Futures Contracts written by
the Fund may also be covered in such other manner as may be in  accordance  with
the  requirements  of the exchange on which they are traded and applicable  laws
and regulations.

The purchase of a put Option on a Futures  Contract is similar in some  respects
to the purchase of protective put options on portfolio securities. The Fund will
purchase  a put  Option on a Futures  Contract  to hedge  the  Fund's  portfolio
against the risk of rising interest rates.

The amount of risk the Fund  assumes  when it  purchases  an Option on a Futures
Contract is the  premium  paid for the option plus  related  transaction  costs,
although in order to realize a profit it may be necessary to exercise the option
and close out the underlying  Futures  Contract.  In addition to the correlation
risks  discussed  above,  the  purchase of an option also  entails the risk that
changes  in the  value  of the  underlying  Futures  Contract  will not be fully
reflected in the value of the option purchased.

ADDITIONAL  RISKS OF OPTIONS ON  SECURITIES,  FUTURES  CONTRACTS  AND OPTIONS ON
FUTURES CONTRACTS: Various additional risks exist with respect to the trading of
options and futures. For example, the Fund's ability effectively to hedge all or
a portion of its portfolio through  transactions in such instruments will depend
on the degree to which price  movements in the  underlying  index or  instrument
correlate with price movements in the relevant portion of the Fund's  portfolio.
The trading of futures and options  entails  the  additional  risk of  imperfect
correlation  between  movements  in the futures or option price and the price of
the underlying  index or  obligation,  while the trading of options also entails
the risk of  imperfect  correlation  between  securities  used to cover  options
written and the  securities  underlying  such options.  The  anticipated  spread
between the prices may be distorted  because of various  factors,  which are set
forth under "Futures Contracts" above. The Fund may also enter into transactions
in such instruments for non-hedging  purposes,  which involves greater risks and
could result in losses which are not offset by gains on other portfolio assets.

The Fund's ability to engage in options and futures  strategies will also depend
on the availability of liquid markets in such instruments.  "Options" above sets
forth certain reasons why a liquid secondary market may not exist.

The liquidity of a secondary  market in a Futures Contract or option thereon may
be  adversely  affected  by "daily  price  fluctuation  limits"  established  by
exchanges  which  limit the  amount of  fluctuation  in the price of a  contract
during a single trading day and prohibit trading beyond such limit. In addition,
the  exchanges  on which  futures and options are traded may impose  limitations
governing  the maximum  number of  positions  on the same side of the market and
involving the same underlying instrument which may be held by a single investor,
whether  acting  alone or in concert  with others  (regardless  of whether  such
contracts are held on the same or different  exchanges or held or written in one
or more accounts or through one or more brokers).

Options on securities  may be traded  over-the-counter.  In an  over-the-counter
trading environment,  many of the protections afforded to exchange  participants
will not be  available.  For example,  there are no clearing  house  performance
guarantees.  In  addition,  there are no daily  price  fluctuation  limits,  and
adverse market movements could therefore  continue to an unlimited extent over a
period of time.  Although the  purchaser of an option  cannot lose more than the
amount of the premium plus related  transaction  costs, this entire amount could
be lost. ----------------

The  investment  objective  and policies  described  above and the policies with
respect  to  portfolio   management  described  below  may  be  changed  without
shareholder approval.

PORTFOLIO  MANAGEMENT:  Although  in many  cases the Fund  will hold  securities
(particularly,  those  which are  unrated  or which are in the  medium and lower
rating  categories) until maturity,  the Fund intends to manage its portfolio by
buying and selling securities to the fullest extent practicable.

In  managing  its  portfolio,  the  Fund  seeks  to  take  advantage  of  market
developments  and yield  disparities,  which may  include  use of the  following
strategies:

    (1) shortening the average  maturity of its portfolio in  anticipation  of a
  rise in interest rates so as to minimize depreciation of principal;

    (2) lengthening  the average  maturity of its portfolio in anticipation of a
  decline in interest rates so as to maximize tax-exempt yield;

    (3)  selling  one type of debt  security  (e.g.,  revenue  bonds) and buying
  another  (e.g.,  general  obligation  bonds)  when  disparities  arise  in the
  relative values of each; and

    (4) changing from one debt security to an essentially  similar debt security
  when their respective yields are distorted due to market factors.

INVESTMENT  RESTRICTIONS.  The Fund has adopted the following restrictions which
cannot be changed  without  the  approval  of the  holders of a majority  of the
shares  of the  Fund  (which  means  the  lesser  of (i)  more  than  50% of its
outstanding shares of the Trust or a series or class, as applicable, or (ii) 67%
or more of the  outstanding  shares  of the  Trust  or a  series  or  class,  as
applicable,  present  at a  meeting  at which  holders  of more  than 50% of the
outstanding  shares  of the  Trust or a series  or  class,  as  applicable,  are
represented in person or by proxy):

The Fund may not:

    (1) borrow  money or pledge,  mortgage  or  hypothecate  in excess of of its
  assets,  except as a temporary measure for extraordinary or emergency purposes
  (the Fund  intends to borrow  money  only from  banks and only to  accommodate
  requests for the  repurchase of shares of the Fund while  effecting an orderly
  liquidation  of portfolio  securities)  (for the purpose of this  restriction,
  collateral  arrangements  with respect to options on fixed income  securities,
  Futures Contracts and Options on Futures Contracts and payments of initial and
  variation  margin  in  connection  therewith  are not  considered  a pledge of
  assets);

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

    (3)  purchase  or sell any put or call  option or any  combination  thereof,
  provided  that this shall not prevent the writing,  purchasing  and selling of
  puts,  calls or  combinations  thereof with respect to securities  and Futures
  Contracts;

    (4) underwrite securities issued by other persons except insofar as the Fund
  may technically be deemed an underwriter  under the Securities Act of 1933, as
  amended, in selling a portfolio security;

    (5) purchase or sell real estate (including  limited  partnership  interests
  but  excluding  securities  secured  by real  estate  or  interests  therein),
  interests in oil, gas or mineral  leases,  commodities or commodity  contracts
  (except  Futures  Contracts and Options on Futures  Contracts) in the ordinary
  course of the business of the Fund (the Fund reserves the freedom of action to
  hold  and to sell  real  estate  acquired  as a  result  of the  ownership  of
  securities);

    (6) purchase  securities  of any issuer if such purchase at the time thereof
  would cause more than 10% of the voting  securities  of such issuer to be held
  by the Fund;

    (7) issue any senior  security  (as that term is  defined in the  Investment
  Company  Act of 1940,  as  amended  (the "1940  Act")),  if such  issuance  is
  specifically  prohibited  by  the  1940  Act  or  the  rules  and  regulations
  promulgated thereunder; and

    (8)  make  loans to  other  persons  except  through  the use of  repurchase
  agreements,  the  purchase  of  commercial  paper or the  purchase of all or a
  portion  of an issue of debt  securities  in  accordance  with its  investment
  objective,  policies and restrictions,  and provided that not more than 10% of
  the Fund's assets will be invested in repurchase  agreements  maturing in more
  than seven days.

As a matter of  non-fundamental  policy,  the Fund may not  knowingly  invest in
securities  (other than  repurchase  agreements),  which are subject to legal or
contractual  restrictions  on resale unless the Board of Trustees has determined
that such  securities  are liquid  based upon  trading  markets for the specific
security,  if more than 15% of the Fund's total assets  (taken at market  value)
would be so invested.

For purposes of the investment  restrictions  described  above and the state and
federal  restrictions  described below,  the issuer of a tax-exempt  security is
deemed to be the  entity  (public or  private)  ultimately  responsible  for the
payment of the principal of and interest on the security.

  STATE AND  FEDERAL  RESTRICTIONS:  In order to comply with  certain  state and
federal statutes, the Fund will not, as a matter of operating policy, (i) invest
more  than 5% of its  total  assets  at the  time  of  investment  in  unsecured
obligations  of issuers  which,  including  predecessors,  controlling  persons,
general  partners  and  guarantors,  have a record  of less  than  three  years'
continuous business operation or relevant business experience,  (ii) purchase or
retain  in its  portfolio  any  securities  issued  by an  issuer  any of  whose
officers,  directors,  trustees or security  holders is an officer or Trustee of
the Fund, or is a member, partner,  officer or Director of the Adviser if, after
the purchase of the  securities of such issuer by the Fund,  one or more of such
persons owns  beneficially  more than 1/2 of 1% of the shares or securities,  or
both,  (all taken at market  value) of such issuer and such persons  owning more
than 1/2 of 1% of such shares or securities  together own beneficially more than
5% of such shares or securities,  or both,  (all taken at market  value),  (iii)
sell any  security  which it does not own unless by virtue of its  ownership  of
other securities the Fund has at the time of sale a right to obtain  securities,
without payment of further  consideration,  equivalent in kind and amount to the
securities  sold and provided that if such right is conditional the sale is made
upon the same conditions,  (iv) invest for the purpose of exercising  control or
management,  or (v)  purchase  securities  issued by any  registered  investment
company except by purchase in the open market where no commission or profit to a
sponsor or dealer results from such purchase  other than the customary  broker's
commission, or except when such purchase, though not made in the open market, is
part of a plan of  merger or  consolidation,  provided,  however,  that the Fund
shall not purchase the securities of any registered  investment  company if such
purchase at the time  thereof  would cause more than 10% of the total  assets of
the Fund  (taken  at market  value) to be  invested  in the  securities  of such
issuers or would cause more than 3% of the outstanding  voting securities of any
such issuer to be held by the Fund,  and provided  further,  that the Fund shall
not  purchase  securities  issued  by any  open-end  investment  company.  These
policies are not fundamental and may be changed by the Fund without  shareholder
approval in response to changes in the various state and federal requirements.

Except for investment  restriction (1) above, these investment  restrictions 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.

3.  MANAGEMENT OF THE FUND

- ----------
*"Interested persons" (as defined in the 1940 Act) of the Adviser, whose address
 is 500 Boylston Street, Boston, Massachusetts 02116.

Each Trustee and officer holds comparable  positions with certain MFS affiliates
or  with  certain  other  funds  of  which  MFS  or a  subsidiary  of MFS is the
investment  adviser or distributor.  Mr. Brodkin,  the Chairman of MFD,  Messrs.
Shames and Scott,  Directors of MFD and Mr.  Cavan,  the  Secretary of MFD, hold
similar positions with certain other MFS affiliates. Mr. Bailey is a Director of
Sun Life Assurance  Company of Canada (U.S.) ("Sun Life of Canada (U.S.)"),  the
corporate parent of MFS.

The Fund pays the  compensation of  non-interested  Trustees and Mr. Bailey (who
currently  receive a fee of $1,250 per year plus $225 per meeting and  committee
meeting attended,  together with such Trustees'  out-of-pocket expenses) and has
adopted a retirement plan for non-interested Trustees and Mr. Bailey. Under this
plan,  a  Trustee  will  retire  upon  reaching  age 73 and if the  Trustee  has
completed  at least  five  years of  service,  he would be  entitled  to  annual
payments  during his  lifetime  of up to 50% of such  Trustee's  average  annual
compensation (based on the three years prior to his retirement) depending on his
length of service. A Trustee may also retire prior to age 73 and receive reduced
payments if he has  completed at least five years of service.  Under the plan, a
Trustee (or his  beneficiaries)  will also receive benefits for a period of time
in the event the Trustee is disabled or dies.  These benefits will also be based
on the Trustee's average annual compensation and length of service.  There is no
retirement  plan provided by the Trust for the interested  Trustees  (except Mr.
Bailey). The Fund will accrue its allocable share of compensation  expenses each
year to cover current year's service and amortize past service cost.

Set  forth in  Appendix  A hereto is  certain  information  concerning  the cash
compensation  paid to  non-interested  Trustees  and  Mr.  Bailey  and  benefits
accrued, and estimated benefits payable, under the retirement plan.

As of May 1, 1995,  all  Trustees  and officers as a group owned less than 1% of
the outstanding  shares of the Fund. As of May 1, 1995,  Merrill Lynch,  Pierce,
Fenner &  Smith,  P.O.  Box  45286,  Jacksonville,  FL was the  record  owner of
approximately 15.4% of the total outstanding Class A shares of the Fund, and was
the record owner of approximately 20.22% of the total outstanding Class B shares
of the Fund.

The Declaration of Trust provides that the Trust will indemnify its Trustees and
officers against liabilities and expenses incurred in connection with litigation
in which they may be involved  because of their offices with the Trust,  unless,
as to liabilities to the Trust or its  shareholders,  it is finally  adjudicated
that they  engaged  in  willful  misfeasance,  bad faith,  gross  negligence  or
reckless  disregard of the duties involved in their offices,  or with respect to
any matter,  unless it is adjudicated that they did not act in good faith in the
reasonable  belief that their actions were in the best interest of the Trust. In
the case of settlement,  such indemnification will not be provided unless it has
been  determined,  pursuant to the  Declaration of Trust,  that such officers or
Trustees have not engaged in willful misfeasance, bad faith, gross negligence or
reckless disregard of their duties.

INVESTMENT ADVISER
MFS and its predecessor  organizations have a history of money management dating
from 1924.  MFS is a subsidiary  of Sun Life of Canada (U.S.) which in turn is a
subsidiary of Sun Life Assurance Company of Canada ("Sun Life").  The Prospectus
contains  information  with respect to the  management  of the Adviser and other
investment companies for which MFS serves as investment adviser.

The Adviser  manages the assets of the Fund pursuant to an  Investment  Advisory
Agreement,  dated  September  1, 1993 (the  "Advisory  Agreement").  The Adviser
provides the Fund with overall investment advisory and administrative  services,
as well as general office  facilities.  Subject to such policies as the Trustees
may determine,  the Adviser makes  investment  decisions for the Fund. For these
services and facilities,  under the Advisory  Agreement,  the Adviser receives a
management  fee,  computed  and paid  monthly,  in an amount equal to the sum of
0.30% of the  Fund's  average  daily net assets  plus 4.75% of the Fund's  gross
income (i.e., income other than gains from the sale of securities), in each case
on an annualized basis, for the Fund's then-current fiscal year.

For the fiscal  years ended  January 31,  1993,  1994 and 1995  management  fees
amounted to $4,921,173,  $5,400,831 and  $6,385,098,  respectively.  In order to
comply with the expense limitations of certain state securities commissions, the
Adviser will reduce its management  fee or otherwise  reimburse the Fund for any
expense, exclusive of interest, taxes and brokerage commissions, incurred by the
Fund in any fiscal year to the extent such expenses exceed the most  restrictive
of such state expense limitations. The Adviser will make appropriate adjustments
to such reimbursements in response to any amendment or rescission of the various
state requirements.

The Fund pays all of its  expenses  (other  than  those  assumed by MFS or MFD),
including:  Trustee fees discussed above,  governmental fees;  interest charges;
taxes;  membership  dues in the Investment  Company  Institute  allocable to the
Fund; fees and expenses of independent  auditors,  of legal counsel,  and of any
transfer agent,  registrar or dividend disbursing agent of the Fund; expenses of
repurchasing and redeeming shares;  expenses of preparing,  printing and mailing
share  certificates,   shareholder   reports,   notices,   proxy  statements  to
shareholders and reports to governmental officers and commissions; brokerage and
other  expenses  connected  with the  execution,  recording  and  settlement  of
portfolio security transactions;  insurance premiums; fees and expenses of State
Street Bank and Trust  Company,  the Fund's  custodian,  for all services to the
Fund,  including  safekeeping of funds and securities and  maintaining  required
books and accounts;  expenses of  calculating  the net asset value of the Fund's
shares; and expenses of shareholder meetings. Expenses relating to the issuance,
registration  and  qualification  of  shares  of the Fund  and the  preparation,
printing  and mailing of  prospectuses  for such  purposes are borne by the Fund
except that the Fund's  Distribution  Agreement with MFD requires MFD to pay for
prospectuses that are to be used for sales purposes. Expenses of the Trust which
are not  attributable  to a specific  series are allocated among the series in a
manner believed by management of the Trust to be fair and equitable.  For a list
of the Fund's expenses,  including the compensation paid to the Trustees who are
not officers of MFS, for the fiscal year ended January 31, 1995,  see "Statement
of  Operations"  in the Fund's Annual  Report to  shareholders  incorporated  by
reference into this SAI.

MFS pays the  compensation of the Trust's  officers and of any Trustee who is an
officer of MFS.  The Adviser  also  furnishes  at its own expense all  necessary
administrative services, including office space, equipment,  clerical personnel,
investment  advisory  facilities,  and all executive and  supervisory  personnel
necessary  for managing the  investments  of the Fund,  effecting  the portfolio
transactions of the Fund and, in general, administering the affairs of the Fund.

The Advisory  Agreement  will remain in effect  until  August 1, 1995,  and will
continue in effect thereafter only if such continuance is specifically  approved
at least  annually  by the Board of  Trustees  or by vote of a  majority  of the
shares of the Fund (as  defined in  "Investment  Restrictions")  and,  in either
case,  by a  majority  of the  Trustees  who are  not  parties  to the  Advisory
Agreement  or  interested  persons of any such  party.  The  Advisory  Agreement
terminates  automatically  if assigned and may be terminated  without penalty by
vote of a  majority  of the  shares  of the  Fund  (as  defined  in  "Investment
Restrictions") or by either party to the Advisory  Agreement on not more than 60
days' nor less than 30 days' written  notice.  The Advisory  Agreement  provides
that if MFS ceases to serve as the Adviser to the Fund, the Fund will change its
name so as to delete the initials "MFS". The Advisory Agreement further provides
that MFS may render  services to others and may permit fund  clients in addition
to the Fund to use the  initials  "MFS" in their names.  The Advisory  Agreement
also provides that neither the Adviser nor its personnel shall be liable for any
error  of  judgment  or  mistake  of law  or for  any  loss  arising  out of any
investment  or for any act or omission in the  execution  and  management of the
Fund,  except for  willful  misfeasance,  bad faith or gross  negligence  in the
performance of its or their duties or by reason of reckless  disregard of its or
their obligations and duties under the Advisory Agreement.

CUSTODIAN
State Street Bank and Trust  Company (the  "Custodian")  is the custodian of the
Fund's  assets.  The  Custodian's   responsibilities   include  safekeeping  and
controlling the Fund's cash and securities, handling the receipt and delivery of
securities,  determining  income and  collecting  interest and  dividends on the
Fund's investments,  maintaining books of original entry for portfolio and trust
accounting and other required books and accounts,  and calculating the daily net
asset  value  of each  class of  shares  of the  Fund.  The  Custodian  does not
determine the  investment  policies of the Fund or decide which  securities  the
Fund will buy or sell. The Fund may,  however,  invest in securities,  including
repurchase  agreements,  issued by the Custodian and may deal with the Custodian
as principal in securities transactions. The Custodian also acts as the dividend
disbursing  agent of the Fund. The Custodian has contracted  with the Adviser to
perform certain accounting  functions related to options  transactions for which
the Adviser receives remuneration on a cost basis.

SHAREHOLDER SERVICING AGENT
MFS Service Center,  Inc. (the "Shareholder  Servicing  Agent"),  a wholly owned
subsidiary  of MFS, is the Fund's  shareholder  servicing  agent,  pursuant to a
Shareholder  Servicing Agent  Agreement,  effective  August 1, 1985 (the "Agency
Agreement") with the Trust. The Shareholder  Servicing Agent's  responsibilities
under the Agency Agreement include  administering and performing  transfer agent
functions, and the keeping of records in connection with the issuance,  transfer
and redemption of the shares of each class of the Fund. For these services,  the
Shareholder  Servicing  Agent will receive a fee based on the net assets of each
class of  shares  of the Fund,  computed  and paid  monthly.  In  addition,  the
Shareholder  Servicing Agent will be reimbursed by the Fund for certain expenses
incurred  by the  Shareholder  Servicing  Agent on behalf  of the Fund.  For the
fiscal year ended  January 31,  1995,  the Fund paid the  Shareholder  Servicing
Agent $1,295,301 for services rendered under the Agency Agreement.  State Street
Bank and Trust Company,  the dividend and  distribution  disbursing agent of the
Fund,  has contracted  with the  Shareholder  Servicing  Agent to administer and
perform certain dividend and distribution disbursing functions for the Fund.

DISTRIBUTOR
MFD, a wholly owned  subsidiary of MFS, serves as distributor for the continuous
offering  of shares of the Fund  pursuant  to a  Distribution  Agreement,  dated
January 1, 1995 (the "Distribution Agreement"), with the Trust. Prior to January
1, 1995, MFS Financial Services,  Inc. ("FSI"),  another wholly owned subsidiary
of MFS, was the Fund's distributor.  Where this SAI refers to MFD in relation to
the  receipt or payment  of money with  respect to a period or periods  prior to
January  1,  1995,  such  reference  shall be  deemed  to  include  FSI,  as the
predecessor  in  interest to MFD.  Prior to that date,  MFS served as the Fund's
principal  underwriter pursuant to a distribution  agreement,  dated January 18,
1984, with the Fund's predecessor.  Except for the periods from March 1, 1989 to
the  close of  business  on March  23,  1989,  February  6, 1990 to the close of
business on February 7, 1990, and on June 3, 1994 only  shareholders of the Fund
have been permitted to purchase  additional Fund shares since June,  1985. As of
the close of business on February 28, 1990,  through November 4, 1990, shares of
the Fund were  also not  available  for sale to  existing  shareholders  (except
through the reinvestment of dividends and capital gains of the Fund).

CLASS A  SHARES:  MFD  acts as agent in  selling  Class A shares  of the Fund to
dealers.  The public  offering  price of Class A shares of the Fund is their net
asset value next computed  after the sale plus a sales charge which varies based
upon the quantity purchased. The public offering price of a Class A share of the
Fund is  calculated  by  dividing  net  asset  value  of a Class A share  by the
difference (expressed as a decimal) between 100% and the sales charge percentage
of  offering  price   applicable  to  the  purchase  (see   "Purchases"  in  the
Prospectus).  The sales  charge  scale set forth in the  Prospectus  applies  to
purchases of Class A shares of the Fund alone or in  combination  with shares of
all classes of certain  other funds in the MFS Family of Funds (the "MFS Funds")
and other funds (as noted under Right of Accumulation) by any person,  including
members of a family unit (e.g., husband, wife, and minor children) and bona fide
trustees,  and also applies to purchases made under the Right of Accumulation or
a Letter of Intent (see  "Investment and Withdrawal  Programs"  below).  A group
might qualify to obtain  quantity sales charge  discounts (see  "Investment  and
Withdrawal Programs" below).

If shares of the Fund are made available for sale, Class A shares may be sold at
their  net  asset  value to  certain  persons  or in  certain  circumstances  as
described  in the  Prospectus.  Such  sales are made  without a sales  charge to
promote good will with  employees  and others with whom MFS, MFD and/or the Fund
have business  relationships,  and because the sales effort, if any, involved in
making such sales is negligible.

MFD allows  discounts  to dealers  (which  are alike for all  dealers)  from the
applicable  public  offering  price of the  Class A  shares.  Dealer  allowances
expressed as a  percentage  of offering  price for all  offering  prices are set
forth in the  Prospectus  (see  "Purchases" in the  Prospectus).  The difference
between the total  amount  invested  and the sum of (a) the net  proceeds to the
Fund and (b) the dealer  commission is the commission  paid to the  distributor.
Because of rounding in the  computation  of offering  price,  the portion of the
sales charge paid to the  distributor may vary and the total sales charge may be
more or less than the sales charge  calculated  using the sales charge expressed
as a  percentage  of the  offering  price or as a  percentage  of the net amount
invested as listed in the  Prospectus.  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.  In addition,  MFD, on behalf of the Fund, pays a commission to
dealers who initiate and are  responsible for purchases of $1 million or more as
described in the Prospectus.

CLASS B  SHARES:  MFD  acts as agent in  selling  Class B shares  of the Fund to
dealers.  The public  offering  price of Class B shares is their net asset value
next computed after the sale (see "Purchases" in the Prospectus).

GENERAL:  Neither MFD nor dealers are permitted to delay the placement of orders
to benefit  themselves by a price change.  On occasion,  MFD may obtain  brokers
loans from various banks,  including the custodian  banks for the MFS Funds,  to
facilitate  the  settlement  of sales of shares of the Fund to dealers.  MFD may
benefit from its temporary holding of funds paid to it by investment dealers for
the purchase of Fund shares.

For the Fund's fiscal year ended January 31, 1995,  gross sales charges on sales
of shares of the Fund amounted to $9,569,708,  of which  $1,576,774 was retained
by  MFD  and   $7,992,934  by  dealers,   banks  and  certain  other   financial
institutions.  The Fund received  $288,599,775,  representing  the aggregate net
asset value of such shares.  For the Fund's  fiscal year ended January 31, 1994,
gross sales  charges on sales of shares of the Fund amounted to  $4,318,254,  of
which $765,746 was retained by MFD and $3,552,508 by dealers,  banks and certain
other financial institutions.  The Fund received $144,059,470,  representing the
aggregate  net asset  value of such  shares.  For the Fund's  fiscal  year ended
January 31, 1993, gross sales charges on sales of shares of the Fund amounted to
$4,557,935,  of which  $807,014 was retained by MFD and  $3,750,921  by dealers,
banks and certain other financial institutions.  The Fund received $143,499,644,
representing the aggregate net asset value of such shares.

For the  Fund's  fiscal  year ended  January  31,  1995 and for the period  from
September 7, 1993 through  January 31, 1994,  the CDSC imposed on  redemption of
Class B shares was $57,796 and $0, respectively.

The Distribution  Agreement will remain in effect until August 1, 1996, and will
continue in effect thereafter only if such continuance is specifically  approved
at least  annually  by the Board of  Trustees  or by vote of a  majority  of the
Trust's shares (as defined in "Investment Restrictions") and, in either case, by
a majority of the Trustees who are not parties to the Distribution  Agreement or
interested  persons of any such party.  The  Distribution  Agreement  terminates
automatically if it is assigned and may be terminated  without penalty by either
party on not more than 60 days' nor less than 30 days' notice.

4.  PORTFOLIO TRANSACTIONS AND BROKERAGE
COMMISSIONS
Specific  decisions  to purchase or sell  securities  for the Fund are made by a
portfolio committee consisting of employees of the Adviser who are appointed and
supervised by its senior  officers.  Changes in the  investments of the Fund are
reviewed by its Board of Trustees. Members of the Fund's portfolio committee may
serve other clients of the Adviser or any subsidiary of the Adviser in a similar
capacity.

The primary  consideration  in portfolio  security  transactions for the Fund is
execution at the most favorable  prices.  The Adviser has complete freedom as to
the  markets  in which,  and the  broker-dealers  through  which,  it seeks this
result.  Municipal Bonds and other debt securities are traded principally in the
over-the-counter  market on a net basis  through  dealers  acting  for their own
account and not as brokers.  The cost of securities  purchased from underwriters
includes an  underwriter's  commission  or  concession,  and the prices at which
securities are purchased and sold from and to dealers include a dealer's mark-up
or  mark-down.  The Adviser  normally  seeks to deal  directly  with the primary
market makers  unless,  in its opinion,  better prices are available  elsewhere.
Subject to the  requirement of seeking  execution at the most  favorable  price,
securities may, as authorized by the Advisory Agreement,  be bought from or sold
to dealers who have  furnished  statistical,  research and other  information or
services to the Adviser or who have sold shares of funds for which MFS serves as
investment adviser. At present no arrangements to recapture  commission payments
are in effect.

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

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

  LETTER OF INTENT:  If a shareholder  (other than a group  purchaser  described
below)  anticipates  purchasing  $100,000  or more of Class A shares of the Fund
alone or in combination with shares of Class B of the Fund or any of the classes
of other MFS Funds or MFS Fixed  Fund  within a  13-month  period   (or 36-month
period,  in the cases of purchases of $1 million or more),  the  shareholder may
obtain Class A shares of the Fund at the same reduced sales charge as though the
total  quantity were invested in one lump sum by completing the Letter of Intent
section of the Fund's Account  Application or filing a separate Letter of Intent
application  (available from the Shareholder  Servicing Agent) within 90 days of
the  commencement of purchases.  Subject to acceptance by MFD and the conditions
mentioned  below,  each  purchase  will  be  made  at a  public  offering  price
applicable to a single  transaction of the dollar amount specified in the Letter
of Intent  application.  The  shareholder or his dealer must inform MFD that the
Letter of Intent is in effect each time shares are  purchased.  The  shareholder
makes no commitment to purchase  additional  shares, but if his purchases within
13 months (or 36 months in the case of purchases of $1 million or more) plus the
value of shares credited toward  completion of the Letter of Intent do not total
the sum  specified,  he will pay the  increased  amount of the  sales  charge as
described  below.  Instructions  for  issuance of shares in the name of a person
other  than  the  person  signing  the  Letter  of  Intent  application  must be
accompanied by a written  statement from the dealer stating that the shares were
paid for by the person signing such Letter. Neither income dividends nor capital
gain  distributions  taken in additional shares will apply toward the completion
of the  Letter  of  Intent.  Dividends  and  distributions  of other  MFS  Funds
automatically  reinvested  in shares of the Fund at net asset value  pursuant to
the Distribution Investment Program will also not apply toward completion of the
Letter of Intent.

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

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

  RIGHT  OF  ACCUMULATION:  A  shareholder  qualifies  for  cumulative  quantity
discounts  on the  purchase  of  Class A  shares  when  that  shareholder's  new
investment,  together with the current  offering  price value of all holdings of
all  classes  of shares of that  shareholder  in the MFS Funds or MFS Fixed Fund
reaches a  discount  level.  See  "Purchases"  in the  Prospectus  for the sales
charges on quantity purchases.  For example, if a shareholder owns shares valued
at $75,000 and purchases $25,000 of Class A shares of the Fund, the sales charge
for the  $25,000  purchase  would be at the rate of 4% (the rate  applicable  to
single  transactions  of $100,000).  A shareholder  must provide the Shareholder
Servicing Agent (or his investment  dealer must provide MFD) with information to
verify that the quantity  sales charge  discount is  applicable  at the time the
investment is made.

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

  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 ("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  generally are limited to 10% of the value
of the account at the time of  establishment  of the SWP. SWP payments are drawn
from the  proceeds of share  redemptions  (which  would be a return of principal
and, if reflecting a gain, would be taxable). Redemptions of Class B shares will
be made in the following order: (i) to the extent necessary,  any "Free Amount";
(ii)  any  "Reinvested  Shares";  (iii) to the  extent  necessary,  the  "Direct
Purchase"  subject to the lowest CDSC (as such terms are defined in  "Contingent
Deferred Sales Charge" in the  Prospectus).  The CDSC will be waived in the case
of  redemptions  of Class B shares  pursuant to a SWP, but will not be waived in
the case of SWP  redemptions  of Class A shares which are subject to a CDSC.  To
the extent that redemptions for such periodic withdrawals exceed dividend income
reinvested  in the  account,  such  redemptions  will reduce and may  eventually
exhaust the number of shares in the  shareholder's  account.  All  dividend  and
capital gain  distributions for an account with a SWP will be reinvested in full
and  fractional  shares of the Fund at the net  asset  value in effect as of the
close of business on the record date for such  distributions.  To initiate  this
service,  shares  generally  having an aggregate value of at least $5,000 either
must be held on deposit by, or  certificates  for such shares must be  deposited
with,  the  Shareholder  Servicing  Agent.  With  respect  to  Class  A  shares,
maintaining a withdrawal plan concurrently  with an investment  program would be
disadvantageous because of the sales charges included in share purchases and the
imposition  of a  CDSC  on  certain  redemptions.  The  shareholder  by  written
instruction  to the  Shareholder  Servicing  Agent may deposit  into the account
additional  shares of the Fund,  change the payee or change the dollar amount of
each  payment.  The  Shareholder  Servicing  Agent may  charge the  account  for
services  rendered and expenses  incurred  beyond those normally  assumed by the
Fund with respect to the liquidation of shares. No charge is currently  assessed
against the account,  but one could be instituted by the  Shareholder  Servicing
Agent on 60 days'  notice in  writing to the  shareholder  in the event that the
Fund ceases to assume the cost of these services. The Fund may terminate any SWP
for an account if the value of the  account  falls  below  $5,000 as a result of
share redemptions  (other than as a result of a SWP) or an exchange of shares of
the Fund for shares of another MFS Fund.  Any SWP may be  terminated at any time
by either the shareholder or the Fund.

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

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

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

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

A shareholder's right to make additional investments in any of the MFS Funds, to
make  exchanges  of shares from one MFS Fund to another and to withdraw  from an
MFS  Fund,  as well as a  shareholder's  other  rights  and  privileges  are not
affected by a shareholder's participation in the Automatic Exchange Plan.

The Automatic  Exchange Plan is part of the exchange  privilege.  For additional
information  regarding the Automatic  Exchange Plan,  including the treatment of
any CDSC, see "Exchange Privilege" below.

  REINSTATEMENT  PRIVILEGE:  Shareholders  of the Fund and  shareholders  of the
other MFS Funds (except MFS Money Market Fund, MFS Government  Money Market Fund
and  holders of Class A shares of MFS Cash  Reserve  Fund in the case where such
shares are acquired  through direct  purchase or reinvested  dividends) 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 the fund are
available  for  sale) at net  asset  value  (without  a sales  charge)  and,  if
applicable,  with credit for any CDSC paid;  however,  only shareholders who are
also  shareholders  of the  Fund may  reinvest  their  proceeds  in the Fund (if
available for sale).  In the case of proceeds  reinvested in shares of MFS Money
Market  Fund,  MFS  Government  Money Market Fund and Class A shares of MFS Cash
Reserve Fund, the  shareholder has the right to exchange the acquired shares for
shares of another MFS Fund at net asset value pursuant to the exchange privilege
described  below.  Such a  reinvestment  must  be  made  within  90  days of the
redemption  and is  limited  to the amount of the  redemption  proceeds.  If the
shares  credited  for any CDSC paid are then  redeemed  within  six years of the
initial purchase for Class B shares (or within 12 months of the initial purchase
of certain  Class A shares),  a CDSC will be imposed upon  redemption.  Although
redemptions and repurchases of shares are taxable events, a reinvestment  within
a certain  period of time in the same fund may be  considered  a "wash sale" and
may result in the inability to recognize  currently all or a portion of any loss
realized on the original redemption for federal income tax purposes.  Please see
your tax adviser for further information.

EXCHANGE  PRIVILEGE -- Subject to the requirements set forth below,  some or all
of the  shares  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 their net asset value. Exchanges will
be made only  after  instructions  in  writing  or by  telephone  (an  "Exchange
Request") are received for an established  account by the Shareholder  Servicing
Agent.

Each Exchange  Request must be in proper form (i.e.,  if in writing -- signed by
the record  owner(s)  exactly as the shares are  registered;  if by telephone --
proper identification is given by the dealer or shareholder of record), and each
exchange must involve either shares having an aggregate value of at least $1,000
($50 in the case of retirement plan participants whose sponsoring  organizations
subscribe to the MFS  FUNDamental  401(k) Plan or another  similar 401(k) record
keeping system made  available by the  Shareholder  Servicing  Agent) or all the
shares in the account.  Each exchange  involves the  redemption of the shares of
the Fund to be exchanged  and the  purchase at net asset value (i.e.,  without a
sales  charge)  of shares of the same  class of the other MFS Fund.  Any gain or
loss  on  the   redemption  of  the  shares   exchanged  is  reportable  on  the
shareholder's federal income tax return. No more than five exchanges may be made
in any one Exchange Request by telephone.  If an Exchange Request is received by
the  Shareholder  Servicing  Agent prior to the close of regular  trading on the
Exchange,  the exchange  usually will occur on that day if all the  requirements
set forth above have been  complied with at that time.  However,  payment of the
redemption  proceeds by the Fund,  and thus the  purchase of shares of the other
MFS Fund, may be delayed for up to seven days if the Fund determines that such a
delay would be in the best interest of all its shareholders.  Investment dealers
which  have  satisfied  criteria  established  by MFD  may  also  communicate  a
shareholder's  Exchange Request to MFD by facsimile  subject to the requirements
set forth above.

No CDSC is imposed on exchanges among the MFS Funds,  although liability for the
CDSC is carried forward to the exchanged 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.

Additional information with respect to any of the MFS Funds, including a copy of
its  current  prospectus,  may  be  obtained  from  investment  dealers  or  the
Shareholder Servicing Agent. A shareholder considering an exchange should obtain
and read the  prospectus of the other MFS Fund and consider the  differences  in
objectives and policies  before making any exchange.  Shareholders  of the other
MFS Funds who are  shareholders  of the Fund  (except  holders  of shares of MFS
Money Market Fund,  MFS  Government  Market Fund, and Class A shares of the Cash
Reserve Fund acquired through direct purchase and dividends  reinvested prior to
June 1, 1992) have the right to exchange  their shares for Class A shares of the
Fund.  subject  to the  conditions,  if  any,  set  forth  in  their  respective
prospectuses.  In addition,  unitholders of the MFS Fixed Fund have the right to
exchange their units (except units acquired through direct purchases) for shares
of the Fund, subject to the conditions, if any, imposed upon such withholders by
the MFS Fixed Fund.

Any state income tax advantages for investment in state-specific  shares of each
series of MFS Municipal Series Trust may only benefit  residents of such states.
Investors  should  consult  with  their own tax  advisers  to be sure this is an
appropriate  investment,  based on their  residency and each state's  income tax
laws.

The exchange  privilege (or any aspect of it) may be changed or discontinued and
is subject to certain  limitations,  including certain restrictions on purchases
by market timer accounts (see "Purchases" in the Prospectus).



6.  TAX STATUS

FEDERAL TAXES
The Fund has  elected  to be  treated  and  intends  to  qualify  each year as a
regulated  investment company under Subchapter M of the Internal Revenue Code of
1986,  as amended (the "Code"),  by meeting all  applicable  Code  requirements,
including  requirements as to the nature of the Fund's gross income,  the amount
of Fund distributions (as a percentage of both the Fund's overall income and its
tax-exempt  income),  and the  composition  and  holding  period  of the  Fund's
portfolio  assets.  Because  the  Fund  intends  to  distribute  all of its  net
investment  income  and  net  realized  capital  gains  to its  shareholders  in
accordance with the timing requirements  imposed by the Code, it is not expected
that the Fund will be required to pay any federal income or excise taxes. If the
Fund should fail to qualify as a "regulated investment company" in any year, the
Fund would incur a regular  corporate federal income tax upon its taxable income
and Fund distributions would generally be taxable as ordinary dividend income to
the shareholders.

That  part  of the  Fund's  distributions  of net  investment  income  which  is
attributable  to interest from  tax-exempt  securities will be designated by the
Fund as an  "exempt-interest  dividend"  under  the Code and will  generally  be
exempt from federal  income tax in the hands of the  shareholders  so long as at
least  50% of the  total  value of the  Fund's  assets  consists  of  tax-exempt
securities   at  the  close  of  each  quarter  of  the  Fund's   taxable  year.
Distributions  of  tax-exempt  interest  earned  from  certain  securities  may,
however,  be treated as  shareholder  tax  preference  items for purposes of the
alternative  minimum  tax, and all such  distributions  may increase a corporate
shareholder's  alternative  minimum tax. The percentage of income  designated as
tax-exempt will be based on the ratio of the Fund's  tax-exempt  income to total
income for the entire fiscal year and is applied  uniformly to all distributions
made during each fiscal year. This percentage,  thus, may differ from the actual
tax exempt percentage for any particular months's distribution.  This tax-exempt
interest  ratio is determined  and reported to  shareholders  after the close of
each fiscal year. Shareholders are required to report exempt-interest  dividends
on their federal income tax returns.

The Fund may  realize  capital  gains  and/or  losses  as the  result  of market
transactions  (including  options and futures  transactions).  Any distributions
from net realized  short-term  capital  gains,  and any  distributions  from net
investment income not designated as an exempt-interest  dividend (such as income
from investments in taxable securities,  including  repurchase  agreements,  and
discount  on bonds  purchased  at a market  discount),  whether  paid in cash or
invested in additional  shares,  are taxable to shareholders as ordinary income.
Distributions  from net capital gains (i.e., the excess of net long-term capital
gains  over  short-term  capital  losses),  whether  paid in cash or  additional
shares,  are taxable to  shareholders  as  long-term  capital  gains for federal
income tax purposes without regard to the length of time the  shareholders  have
held their shares. Any Fund dividend that is declared in October,  November,  or
December of any calendar year that is payable to  shareholders of record in such
a month,  and that is paid the following  January will be treated as if received
by the  shareholders  on  December  31 of the  year in  which  the  dividend  is
declared. The federal income tax status of all distributions will be reported to
shareholders annually.

Since all of the  income of the Fund is  expected  to arise  from  interest  and
capital gains, no part of the distributions to its shareholders will qualify for
the dividends-received deduction for corporations.

Any dividend or distribution  will have the effect of reducing the per share net
asset value of shares in the Fund by the amount of the dividend or distribution.
Shareholders  purchasing  shares  shortly  before the record date of any taxable
dividend  or other  taxable  distribution  may thus pay the full  price  for the
shares and then  effectively  receive a portion of the purchase  price back as a
taxable distribution.

In addition,  shareholders  disposing of shares after tax-exempt income has been
accrued but not yet declared as a dividend should be aware that a portion of the
sales proceeds realized upon disposition of the shares may reflect the existence
of such accrued  tax-exempt income, and that such portion of the proceeds may be
subject to tax as a capital gain even though it would have been  tax-exempt  had
it been declared as a dividend prior to the  disposition.  Redemptions of shares
of the Fund can be effected with the least adverse tax consequences  immediately
after  the third  business  day of any  month  (the  time at which the  dividend
representing substantially all the income accrued for that month is declared).

In general,  any gain or loss realized upon a taxable  disposition  of shares of
the Fund by a  shareholder  that  holds such  shares as a capital  asset will be
treated as long-term  capital gain or loss if the shares have been held for more
than twelve months and otherwise as a short-term capital gain or loss.  However,
any loss realized  upon a disposition  of shares in the Fund held for six months
or less  will be  disallowed  to the  extent  of any  exempt-interest  dividends
received with respect to those shares and, if not disallowed, any such loss will
be treated as a long-term capital loss to the extent of any distributions of net
capital  gain  made with  respect  to those  shares.  Any loss  realized  upon a
disposition of shares may also be disallowed under rules relating to wash sales.
Gain may be increased  (or loss  reduced) upon a redemption of Class A shares of
the Fund  within  ninety  days after their  purchase  followed  by any  purchase
(including  purchases  by exchange  or by  reinvestment)  without  payment of an
additional sales charge of Class A shares of the Fund or of another MFS Fund (or
any other shares of an MFS Fund generally sold subject to a sales charge).

Exempt-interest  dividends are taken into account in  calculating  the amount of
social security and railroad  retirement benefits that may be subject to federal
income tax.

Interest on  indebtedness  incurred  (directly or indirectly) by shareholders to
purchase or carry shares of the Fund will not be deductible  for federal  income
tax purposes.  Further,  persons who are "substantial users" (or persons related
thereto) of facilities financed by certain private activity bonds should consult
their own tax advisers before purchasing shares of the Fund.  "Substantial user"
is defined generally as including a "non-exempt  person" who regularly uses in a
trade or  business a part of a facility  financed  from the  proceeds of certain
private activity bonds.

The Fund's  transactions  in options  and Futures  Contracts  will be subject to
special  tax rules that may affect the amount,  timing,  and  character  of Fund
income and distributions to shareholders. For example, certain positions held by
the Fund on the last  business day of each taxable year will be marked to market
(i.e.,  treated as if closed out) on such day,  and any gain or loss  associated
with the positions will be treated as 60% long-term and 40%  short-term  capital
gain or loss. Certain positions held by the Fund that substantially diminish its
risk of loss with respect to other  positions in its  portfolio  may  constitute
"straddles,"  and may be subject to special tax rules that would cause  deferral
of Fund  losses,  adjustments  in the holding  periods of Fund  securities,  and
conversion of short-term into long-term  capital  losses.  Certain tax elections
exist for  straddles  that may alter the effects of these  rules.  The Fund will
limit its activities in options and Futures Contracts to the extent necessary to
meet the requirements of Subchapter M of the Code.

The Fund's  current  dividend  and  accounting  policies  may affect the amount,
timing,  and character of  distributions  to shareholders and may, under certain
circumstances,  make an economic return of capital taxable to shareholders.  The
Fund's  investment  in  zero  coupon  securities,  certain  stripped  tax-exempt
obligations, and certain securities purchased at a market discount will cause it
to realize  income prior to the receipt of cash  payments  with respect to these
securities.  In order to distribute this income and avoid a tax on the Fund, the
Fund may be required to liquidate  portfolio  securities that it might otherwise
have continued to hold, potentially resulting in additional taxable gain or loss
to the Fund.

Dividends  and  certain  other  payments  to  persons  who are not  citizens  or
residents  of the  United  States  or U.S.  entities  ("Non-U.S.  Persons")  are
generally  subject to U.S. tax  withholding at the rate of 30%. The Fund intends
to withhold tax at the rate of 30% on any such  dividends  and payments  made to
Non-U.S.  Persons that are subject to such withholding,  regardless of whether a
lower treaty rate may be permitted. Any amounts overwithheld may be recovered by
such persons by filing a claim for refund with the U.S. Internal Revenue Service
within the time period applicable to such claims.  Non-U.S.  Persons may also be
subject to tax under the laws of their own jurisdiction.

The Fund is also required in certain  circumstances to apply backup  withholding
at a rate  of 31% on  taxable  dividends  and  redemption  proceeds  paid to any
shareholder  (including  a  Non-U.S.  Person)  who does not  furnish to the Fund
certain  information and  certifications  or who is otherwise  subject to backup
withholding.  However,  backup withholding will not be applied to payments which
have been subject to 30% withholding.

STATE AND LOCAL TAXES
As long as it qualifies as a regulated  investment  company under the Code,  the
Fund will not be  required  to pay  Massachusetts  income or excise  taxes.  The
exemption of exempt-interest  dividends for federal income tax purposes does not
necessarily  result in exemption under the tax laws of any state or local taxing
authority.  Some states do exempt  from  tax that  portion of an exempt-interest
dividend which represents interest received by a regulated investment company on
its holdings of Municipal Bonds of that state and its political subdivisions and
instrumentalities.  Therefore, the Fund will report annually to its shareholders
the  percentage of interest  income earned by the Fund during the preceding year
from Municipal Bonds indicating,  on a state-by-state  basis only, the source of
such  income.  Each  shareholder  is  advised  to  consult  his own tax  adviser
regarding the exemption of exempt-interest  dividends under applicable state and
local law.


7.  DETERMINATION OF NET ASSET VALUE AND PERFORMANCE

NET  ASSET  VALUE:  The net asset  value per share of each  class of the Fund is
determined  each day during which the  Exchange is open for trading.  (As of the
date of this SAI, the Exchange is open for trading every weekday  except for the
following  holidays  or the day on which  they are  observed:  New  Year's  Day,
Presidents'  Day,  Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving Day and Christmas Day.) This determination is made once during each
day as of the close of regular  trading on the Exchange by deducting  the amount
of the  liabilities  attributable  to the  class  from the  value of the  assets
attributable to the class and dividing the difference by the number of shares of
the class  outstanding.  Debt securities  (other than  short-term  obligations),
including  listed  issues,  are valued on the basis of  valuations  furnished by
pricing service,  which utilizes both dealer-supplied  valuations and electronic
data processing  techniques which take into account  appropriate factors such as
institutional-size  trading in similar  groups of  securities,  yield,  quality,
coupon rate, maturity,  type of issue, trading  characteristics and other market
data, without exclusive reliance upon exchange or over-the-counter prices, since
such valuations are believed to reflect the fair value of such  securities.  Use
of the pricing services has been approved by the Board of Trustees. Positions in
listed options, Futures Contracts and Options on Futures Contracts will normally
be valued at the  closing  settlement  price on the  exchange  on which they are
primarily traded.  Short-term obligations with a remaining maturity in excess of
60 days will be valued based upon dealer supplied  valuations.  Other short-term
obligations  are  valued  at  amortized  cost,  unless  the  Board  of  Trustees
determines   that  this  does  not   constitute   fair   value.   Positions   in
over-the-counter  options  will be  valued  using  dealer  supplied  valuations.
Portfolio  securities for which there are no such  valuations are valued at fair
value  as  determined  in good  faith  by or at the  direction  of the  Board of
Trustees.

PERFORMANCE INFORMATION
TOTAL RATE OF RETURN:  The Fund will calculate its total rate of return for each
class of shares for certain periods by determining the average annual compounded
rates of return  over those  periods  that would cause an  investment  of $1,000
(made with all  distributions  reinvested and reflecting the CDSC or the maximum
offering price) to reach the value of that investment at the end of the periods.
The Fund may also calculate (i) a total rate of return,  which is not reduced by
the CDSC (4%  maximum for Class B shares  purchased  on and after  September  1,
1993) and therefore may result in a higher rate of return,  (ii) a total rate of
return  assuming  an initial  account  value of $1,000,  which will  result in a
higher rate of return since the value of the initial account will not be reduced
by the current maximum sales charge (currently 4.75%),  and/or (iii) total rates
of return which represent  aggregate  performance  over a period or year-by-year
performance, and which may or may not reflect the effect of the maximum or other
sales charge or CDSC. The Fund's average annual total rate of return for Class A
shares,  reflecting the initial investment at the maximum public offering price,
for the  one-year,  five-year  and ten-year  periods ended January 31, 1995 was,
- -5.76%, 5.32% and 7.25%,  respectively.  The Fund's average annual total rate of
return, not giving effect to the sales charge on the initial investment, for the
one-year,  five-year and ten-year  periods ended January 31, 1995, was,  -1.04%,
6.35% and 7.77%,  respectively.  The Fund's  average annual total rate of return
for Class B shares reflecting the CDSC for the one-year period ended January 31,
1995 and for the period  September 7, 1993 through the Fund's  fiscal year ended
January 31, 1995 was -5.79% and -2.83%, respectively.  The Fund's average annual
total rate of return for Class B shares,  not giving  effect to the CDSC for the
one-year  period  ended  January 31, 1995 and for the period  September  7, 1993
through  the Fund's  fiscal  year ended  January 31, 1995 was -2.13% and -0.20%,
respectively.

PERFORMANCE  RESULTS: The performance results for Class A shares below, based on
an assumed  initial  investment  of $10,000 in Class A shares,  cover the period
from January 1, 1985 to December 31,  1994.  It has been assumed that  dividends
and capital gain  distributions  were  reinvested  in additional  shares.  These
performance results, as well as any yield, tax-equivalent yield or total rate of
return   quotation   provided  by  the  Fund,   should  not  be   considered  as
representative  of the performance of the Fund in the future since the net asset
value and public  offering  price of shares of the Fund will vary based not only
on the  type,  quality  and  maturities  of the  securities  held in the  Fund's
portfolio,  but also on changes in the current value of such  securities  and on
changes in the expenses of the Fund.  These factors and possible  differences in
the methods used to calculate yields,  tax-equivalent  yields and total rates of
return should be considered when comparing the  yield,  tax-equivalent yield and
total rate of return  of  the Fund to  yields,  tax-equivalent  yields and total
rates of return  published for other  investment  companies or other  investment
vehicles.  Total rate of return  reflects the  performance of both principal and
income. Current net asset value of shares of the Fund as well as account balance
information may be obtained by calling 1-800-MFS-TALK (637-8255).

EXPLANATORY  NOTES:  The  results  shown in the table  assume  that the  initial
investment in the Fund was made on January 1, 1985. The results also assume that
the initial  investment  in the Fund was reduced by the  current  maximum  sales
charge  (4.75%).  No  adjustment  has been made for any income taxes  payable by
shareholders.

YIELD:  Any  yield  quotation  for a class of shares of the Fund is based on the
annualized  net  investment  income  per share of that  class of the Fund over a
30-day  period.  The yield for each class of the Fund is  calculated by dividing
the net  investment  income  allocated to that class earned during the period by
the maximum  offering  price per share of that class of the Fund on the last day
of that period.  The resulting figure is then annualized.  Net investment income
per share of a class is  determined  by dividing (i) the  dividends and interest
allocated to that class during the period,  minus accrued expenses of that class
for the period,  by (ii) the average  number of shares of the class  entitled to
receive dividends during the period multiplied by the maximum offering price per
share of such class on the last day of the period. The Fund's yield calculations
for Class A shares assume a maximum sales charge of 4.75%. The yield calculation
for Class B shares  assumes no CDSC is paid. The Fund's yield for Class A shares
for the 30-day  period ended  January 31, 1995 was 7.13%.  The yield for Class B
shares of the Fund for the 30-day period ended January 31, 1995 was 6.41%.

TAX-EQUIVALENT  YIELD:  The  Fund's  tax-equivalent  yield  for  each  class  is
calculated by determining the rate of return that would have to be achieved on a
fully taxable  investment  to produce the after-tax  equivalent of the yield for
that class.  In  calculating  tax-equivalent  yield,  the Fund  assumes  certain
federal tax  brackets  for  shareholders  and does not take into  account  state
taxes. The Fund's  tax-equivalent yield for Class A shares for the 30-day period
ended  January  31,  1995 was 9.90%  (assuming  a tax bracket of 28%) and 10.33%
(assuming a tax bracket of 31%). The tax-equivalent  yield for Class B shares of
the Fund for the 30-day period ended January 31, 1995 was 8.90%  (assuming a tax
bracket of 28%) and 9.29% (assuming a tax bracket of 31%).

CURRENT  DISTRIBUTION  RATE: Yield,  which is calculated  according to a formula
prescribed by the Securities and Exchange  Commission,  is not indicative of the
amounts which were or will be paid to the Fund's  shareholders.  Amounts paid to
shareholders  of each class are  reflected in the quoted  "current  distribution
rate" for that class. The current  distribution  rate for a class is computed by
dividing  the  total  amount  of  dividends  per  share  paid  by  the  Fund  to
shareholders  of that class during the past twelve months by the maximum  public
offering  price  of  that  class  at  the  end of  such  period.  Under  certain
circumstances,  such as when there has been a change in the  amount of  dividend
payout, or a fundamental change in investment policies,  it might be appropriate
to annualize  the  dividends  paid over the period such policies were in effect,
rather  than using the  dividends  during the past  twelve  months.  The current
distribution  rate  differs  from the yield  computation  because it may include
distributions  to  shareholders  from sources other than dividends and interest,
such as premium income for option writing,  short-term  capital gains and return
of invested  capital,  and is calculated  over a different  period of time.  The
Fund's  current  distribution  rate  calculation  for  Class A shares  assumes a
maximum sales charge of 4.75%. The Fund's current  distribution rate calculation
for Class B shares  assumes no CDSC is paid. The current  distribution  rate for
Class A shares of the Fund for the twelve-month period ended on January 31, 1995
was 7.81%. The current  distribution rate for Class B shares of the Fund for the
twelve-month period ended January 31, 1995 was 6.68%.

From time to time the Fund may, as  appropriate,  quote Fund rankings or reprint
all or a portion of evaluations of fund performance and operations  appearing in
various  independent  publications,  including but not limited to the following:

performance  may also be  compared  to the  performance  of other  mutual  funds
tracked by financial or business publications or periodicals.  The Fund may also
quote evaluations mentioned in independent radio or television  broadcasts,  and
use charts and graphs to illustrate the past performance of various indices such
as those mentioned above and illustrations using hypothetical rates of return to
illustrate the effects of compounding and  tax-deferral.  The Fund may advertise
examples of the effects of periodic investment plans, including the principle of
dollar cost  averaging.  In such a program,  an investor  invests a fixed dollar
amount in a fund at periodic  intervals,  thereby  purchasing  fewer shares when
prices are high and more shares when prices are low.  While such a strategy does
not  assure  a  profit  or  guard  against  a loss in a  declining  market,  the
investor's  average cost per share can be lower than if fixed  numbers of shares
are purchased at the same intervals.

8.  DISTRIBUTION PLAN
CLASS B  DISTRIBUTION  PLAN:  The  Trustees  have  adopted a  Distribution  Plan
relating to Class B shares (the "Class B Distribution Plan") pursuant to Section
12(b) of the 1940 Act and Rule  12b-1  thereunder  (the  "Rule"),  after  having
concluded that there was a reasonable  likelihood  that the Class B Distribution
Plan  would  benefit  the  Fund  and  its  Class  B  shareholders.  The  Class B
Distribution  Plan is  designed to promote  sales,  thereby  increasing  the net
assets of the Fund.  Such an increase may reduce the expense ratio to the extent
the  Fund's  fixed  costs are  spread  over a larger net asset  base.  Also,  an
increase in net assets may lessen the adverse effects that could result were the
Fund required to liquidate portfolio  securities to meet redemptions.  There is,
however,  no assurance that the net assets of the Fund will increase or that the
other benefits referred to above will be realized.

The Class B Distribution Plan provides that the Fund will pay MFD, as the Fund's
distributor for its Class B shares, 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 may pay MFD an  annual  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% per annum of the Fund's average daily net assets  attributable to
Class B shares owned by investors for whom that securities  dealer is the holder
or  dealer  of  record).   This  service  fee  is  intended  to  be   additional
consideration  for all personal  services  and/or account  maintenance  services
rendered by the dealer with respect to Class B shares. Except in the case of the
first year service  fee, no service fee will be paid.  This  elimination  of the
service fee may be amended or terminated  without  notice to  shareholders.  MFD
will advance to dealers the first-year  service fee at a rate equal to 0.25% per
annum of the  amount  invested.  As  compensation  therefor,  MFD may retain the
service  fee paid by the Fund with  respect  to such  shares  for the first year
after purchase.  Dealers will become  eligible for additional  service fees with
respect to such shares  commencing in the thirteenth  month following  purchase.
Except in the case of the first year service fee, no service fee will be paid to
any  securities  dealer who is the holder or dealer of record for  investors who
own Class B shares having an aggregate net asset value of less than $750,000, or
such other amount as may be determined  from time to time by MFD. MFD,  however,
may waive  this  minimum  amount  requirement  from  time to time if the  dealer
satisfies  certain  criteria.  Dealers may from time to time be required to meet
certain other  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 distribution  payments to MFD under the Class B Distribution Plan
is to  compensate  MFD for its  distribution  services  to the  Fund.  MFD  pays
commissions to dealers as well as expenses of printing  prospectuses and reports
used for sales  purposes,  expenses with respect to the preparation and printing
of sales literature and other distribution related expenses,  including, without
limitation,  the cost necessary  to  provide  distribution-related services,  or
personnel,  travel office expenses and equipment.  The Class B Distribution Plan
also  provides that MFD will receive all CDSCs  attributable  to Class B shares.
(See  "Distribution  Plan" and  "Purchases" in the  Prospectus.)  For the Fund's
fiscal year ended January 31, 1995 and for the period  September 7, 1993 through
January  31,  1995,  the Fund paid  Class B  distribution  and  service  fees of
$335,495 and $335,548,  respectively (equal to 0.99% and 1.00%, respectively, of
the Fund's average daily net assets attributable to Class B shares).

In accordance with the Rule, all agreements relating to the Class B Distribution
Plan  entered  into  between  the Fund or MFD and  other  organizations  must be
approved by the Board of Trustees,  including a majority of the Trustees who are
not "interested  persons" (as defined in the 1940 Act) and who have no direct or
indirect financial interest in the operation of the Class B Distribution Plan or
in any  agreement  related to such Plan ("Class B  Distribution  Plan  Qualified
Trustees").  The Class B Distribution  Plan further  provides that the selection
and  nomination  of  Class B  Distribution  Plan  Qualified  Trustees  shall  be
committed to the discretion of the non-interested Trustees then in office.

The Class B  Distribution  Plan will remain in effect until August 1, 1995,  and
will continue in effect  thereafter  only if such  continuance  is  specifically
approved at least annually by vote of the Trustees and a majority of the Class B
Distribution  Plan Qualified  Trustees.  The Class B Distribution  Plan requires
that the Fund and MFD shall  provide to the  Trustees,  and the  Trustees  shall
review,  at least  quarterly,  a written  report of the  amounts  expended  (and
purposes  therefor)  under  such  Plan.  The  Class B  Distribution  Plan may be
terminated  at any time by vote of a majority of the Class B  Distribution  Plan
Qualified Trustees or by vote of the holders of a majority of the Class B shares
of the Fund  (as  defined  in  "Investment  Restrictions"  above).  The  Class B
Distribution  Plan may not be  amended  to  increase  materially  the  amount of
permitted distribution expenses without the approval of Class B shareholders and
may not be materially amended in any case without a vote of the majority of both
the Trustees and the Class B Distribution  Plan Qualified  Trustees.  No Trustee
who is not an interested  person of the Fund has any  financial  interest in the
Class B Distribution Plan or in any related agreement.

9.  DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES
The  Declaration  of Trust permits the Trustees to issue an unlimited  number of
full and fractional Shares of Beneficial  Interest (without par value) of one or
more  separate  series and to divide or combine  the shares of any series into a
greater or lesser number of shares without  thereby  changing the  proportionate
beneficial  interests in that series.  The Trustees  have  currently  authorized
shares  of the Fund and one  other  series.  The  Declaration  of Trust  further
authorizes  the Trustees to classify or reclassify any series of shares into one
or more classes.  Pursuant thereto, the Trustees have authorized the issuance of
three classes of shares of the Fund, Class A shares,  Class B shares and Class C
shares.  Each  share of a class of the Fund  represents  an equal  proportionate
interest in the assets of the Fund allocable to that class.  Upon liquidation of
the Fund,  shareholders of each class of the Fund are entitled to share pro rata
in the net assets of the Fund allocable to such class available for distribution
to its shareholders. The Trust reserves the right to create and issue additional
classes  or series of  shares,  in which case the shares of each class or series
would  participate  equally in the earnings,  dividends and assets  allocable to
that class of the particular series.

Shareholders  are  entitled  to one vote for each share held and may vote in the
election of Trustees and on other matters submitted to meetings of shareholders.
Although  Trustees are not elected  annually by the  shareholders,  shareholders
have under  certain  circumstances  the right to remove one or more  Trustees in
accordance  with the  provisions  of section  16(c) of the 1940 Act. No material
amendment  may  be  made  to  the  Trust's  Declaration  of  Trust  without  the
affirmative vote of a majority of the shares of the Trust or by an instrument in
writing  without a meeting  signed by a majority of Trustees and consented to by
more  than  50% of the  shares  of the  Fund.  Shares  have  no  pre-emptive  or
conversion  rights  (except as described in  "Purchases -- Conversion of Class B
Shares" in the Prospectus). Shares are fully paid and non-assessable.  The Trust
may enter into a merger or  consolidation,  or sell all or substantially  all of
its assets (or all or substantially all of the assets belonging to any series of
the Trust),  if approved by the vote of the holders of two-thirds of the Trust's
outstanding  shares voting as a single class,  or of the affected  series of the
Trust,  as the case may be,  except that if the Trustees of the Trust  recommend
such  merger,  consolidation  or sale,  the approval by vote of the holders of a
majority of the Trust's or the affected series'  outstanding  shares (as defined
in "Investment Restrictions") will be sufficient. The Trust or any series of the
Trust  may also be  terminated  (i) upon  liquidation  and  distribution  of its
assets,  if approved by the vote of the holders of two-thirds of its outstanding
shares,  or (ii) by the Trustees by written  notice to the  shareholders  of the
Trust or the  affected  series.  If not so  terminated  the Trust will  continue
indefinitely.

The Trust is an entity of the type commonly known as a  "Massachusetts  business
trust". Under Massachusetts law, shareholders of such a trust may, under certain
circumstances,  be held  personally  liable  as  partners  for its  obligations.
However,  the Declaration of Trust contains an express disclaimer of shareholder
liability for acts or obligations of the Trust and provides for  indemnification
and reimbursement of expenses out of the Trust property for any shareholder held
personally  liable for the  obligations of the Trust.  The  Declaration of Trust
also provides that the Trust shall maintain appropriate  insurance (for example,
fidelity  bonding and errors and omissions  insurance) for the protection of the
Trust,  its  shareholders,  Trustees,  officers,  employees and agents  covering
possible tort and other liabilities.  Thus, the risk of a shareholder  incurring
financial loss on account of shareholder  liability is limited to  circumstances
in which both  inadequate  insurance  existed and the Trust itself was unable to
meet its obligations.

The Declaration of Trust further  provides that obligations of the Trust are not
binding upon the Trustees  individually  but only upon the property of the Trust
and that the  Trustees  will not be liable for any action or failure to act, but
nothing in the  Declaration of Trust protects a Trustee against any liability to
which he would otherwise be subject by reason of willful misfeasance, bad faith,
gross negligence or reckless  disregard of the duties involved in the conduct of
his office.

LETTER  TO  SHAREHOLDERS

Dear Shareholders:
During  the fiscal  year  ended  January  31,  1995,  Class A shares of the Fund
provided a total  return of -1.04%,  while Class B shares had a total  return of
- -2.13%.  Both of these figures  assume the  reinvestment  of  distributions  but
exclude  the  effects of any sales  charges.  The Fund's  performance  over this
period was quite favorable  relative to the -3.56% return of the Lehman Brothers
Municipal  Bond Index.  However,  it is  important to note that the Lehman Index
represents an unmanaged index of  investment-grade  municipal bonds rated Baa or
higher, while the Fund invests primarily in lower-quality municipal issues which
are rated Baa or below,  or are  unrated.  A  discussion  of the Fund's  results
relative  to the  Lehman  Index may be found in the  Portfolio  Performance  and
Strategy section below.

Economic Outlook
The economic expansion,  entering its fifth year, gained firmer underpinnings in
1994 as employers significantly stepped up hiring levels.  Increased employment,
stronger capital spending by businesses,  and strengthening  overseas  economies
resulted in 4% real (adjusted for inflation)  gross domestic product growth last
year.  Interest rates rose  substantially  over the past year, which should help
restrain,  but not curtail, the economic expansion.  Based on improving economic
fundamentals both here and abroad, we expect the business  expansion to continue
well into 1995.

Interest Rates
Despite a  stronger  economy,  inflation  at the  consumer  level  has  remained
relatively benign at 2.7% in 1994, the fourth straight year of 3.0% or less. Due
to a  prolonged  period of  below-trend-line  growth and  continued  pressure on
corporations  to emphasize  effective cost controls,  wage growth and unit labor
costs have remained subdued.  However,  as the economy has exhibited  continuing
strength,  various  industrial  commodity prices have been rising  substantially
faster  than  consumer  prices.  Nevertheless,  businesses  have had  difficulty
passing these price increases on to the consumer. With the economy continuing to
expand,  we expect some upward movement in inflation from below 3% to the 3 1/2%
range.  The Federal  Reserve Board has shown a willingness  to raise  short-term
rates to slow the economy to dampen inflationary  pressures.  Most recently,  it
raised the federal  funds rate 50 basis points  (0.50%)  after a 75  basis-point
(0.75%) increase in November.  We expect the Federal Reserve to raise short-term
rates again in the coming months if it believes its current  efforts have failed
to dampen  inflationary  expectations.  Although  we  believe  fundamentals  are
favorable for lower  long-term  rates sometime in 1995, this may not occur until
the Federal Reserve feels that its policy toward slowing the economic  expansion
has been successful.  Thus, we believe that long-term yields may move moderately
higher in the near term.

Municipal Bond Market
The municipal bond market ended the calendar year on an unsettling  note because
of the bankruptcy  filing of Orange County,  California and the uncertain effect
this  will  have on other  tax-exempt  bonds.  Although  the Fund had no  direct
exposure to Orange County  itself,  1.5% of total Fund assets is invested in two
issues of the San  Joaquin  Transportation  Corridor  Agency.  This  Agency  has
invested  one-half  of its  construction  funds  and  all  of  its  construction
contingency  funds  with the  County.  It is now up to the  bankruptcy  court to
determine the plan of disbursement of funds held within the County's  investment
pool.  We will  closely  monitor  this  situation  but, at this time,  we do not
believe it will adversely impact the Fund.

<PAGE>
LETTER  TO  SHAREHOLDERS  - continued
    The supply of municipal bonds in 1994 decreased 44% from the record-breaking
issuance in 1993,  and is not  expected to increase in 1995.  Selling  pressures
which  plagued  municipal  bond  performance  during  the  year as a  result  of
market-related  and  tax-related  transactions  are expected to abate. So far in
1995, the supply picture has not improved.  Issuance during the month of January
was 40% of that in  January  of 1994.  The  anti-big  government,  tax-  cutting
sentiment,  which played an important  role in the  November  elections,  should
hamper growth in municipal  capital  spending in the near term. This shortage of
supply,  combined  with the  anticipated  return to bond funds of retail  buyers
unable to purchase  individual  bonds,  in our opinion  bodes well for municipal
bond funds during the year ahead.

Portfolio Performance and Strategy
The Fund's  outperformance  relative to the Lehman  Index during the fiscal year
ended January 31, 1995 can be attributed to its high concentration of bonds with
higher-than-market  stated coupons, which are associated with lower-rated bonds.
Generally, these securities are less price sensitive in a volatile interest rate
environment  and provide  less price  fluctuation  during  these  periods.  This
portfolio  structure  is  consistent  with the Fund's  investment  objective  of
providing  a  high  level  of  current   tax-exempt   income  through  generally
lower-rated  or unrated  securities.  Based on our outlook for interest rates in
1995,  capital  appreciation  in the Fund over the  coming  year is likely to be
minimal,  and  interest  income  should make up a  significant  component of the
Fund's total return.

    Our efforts  remain  focused on research  and  preservation  of high current
tax-exempt  income. We continue to closely monitor our holdings and seek out new
opportunities for investment.  This past year has seen credit concerns regarding
Orange County and the much anticipated  opening of the new Denver  International
Airport,  as well as a plethora of financings for de-inked paper  facilities and
co-generation power plants. Diversification of credit risk and liquidity factors
remain important components of the Fund's overall strategy.

    We  appreciate  your  support and welcome any  questions or comments you may
have.

Respectfully,

PORTFOLIO  MANAGER  PROFILE
Cynthia Brown began her career at MFS in 1986 in the Fixed Income Department.  A
graduate  of  Boston  University,  she was  named  Investment  Officer  in 1986,
Assistant  Vice  President  in 1987,  Vice  President  in 1989 and  Senior  Vice
President in 1994. In addition to managing MFS Municipal  High Income Fund,  she
oversees  MFS(R)  Municipal  Income  Trust.  Ms. Brown is a member of the Boston
Municipal Analysts Group.

OBJECTIVE  AND  POLICY
The Fund's  investment  objective is to provide high current  income exempt from
federal income taxes.

The Fund's  investment  policy is to invest  primarily in debt  securities,  the
interest on which is exempt from federal income tax. Generally, these securities
are in the medium- and lower-rated categories or are unrated. The Fund may enter
into  futures  contracts  and options on futures  contracts  to protect  against
anticipated  changes in  interest  rates.  The Fund may also enter into  options
transactions and purchase securities on a "when-issued" basis.

TAX  FORM  SUMMARY
In January  1995,  shareholders  were mailed a Tax Form  Summary  reporting  the
federal tax status of all distributions  paid during the calendar year 1994. For
the year ended January 31, 1995, the  distributions  from  investment  income of
Class A and Class B shares were $0.67 and $0.57, respectively.

For federal  income tax purposes,  100% of the total  dividends paid by the Fund
from net investment  income during the year ended January 31, 1995 is designated
as an exempt-interest dividend.

PERFORMANCE
The information on the following page illustrates the historical  performance of
MFS Municipal  High Income Fund Class A shares in  comparison to various  market
indicators.  Class A share  results  reflect the  deduction of the 4.75% maximum
sales charge; benchmark comparisons are unmanaged and do not reflect any fees or
expenses. You cannot invest in an index. All results reflect the reinvestment of
all dividends and capital gains.

Please note that  effective  September  7, 1993,  Class B shares  were  offered.
Information on Class B share performance appears on the next page.

NOTES  TO  FINANCIAL  STATEMENTS
(1) Business  and  Organization
MFS  Municipal  High Income Fund (the Fund) is a  non-diversified  series of MFS
Series Trust III (the Trust). The Trust is organized as a Massachusetts business
trust and is registered under the Investment Company Act of 1940, as amended, as
an open-end management investment company.

(2) Significant  Accounting  Policies
Investment Valuations - Debt securities (other than short-term obligations which
mature in 60 days or less),  including listed issues, are valued on the basis of
valuations  furnished by dealers or by a pricing service with  consideration  to
factors  such as  institutional-size  trading in similar  groups of  securities,
yield, quality,  coupon rate, maturity,  type of issue, trading  characteristics
and  other  market  data,   without   exclusive   reliance   upon   exchange  or
over-the-counter  prices.  Short-term  obligations,  which  mature in 60 days or
less, are valued at amortized cost,  which  approximates  market value.  Futures
contracts,  options  and  options on  futures  contracts  listed on  commodities
exchanges are valued at closing settlement prices. Over-the- counter options are
valued by brokers  through the use of a pricing  model which takes into  account
closing bond valuations,  implied  volatility and short-term  repurchase  rates.
Securities  for which there are no such  quotations or valuations  are valued at
fair value as determined in good faith by or at the direction of the Trustees.

Repurchase  Agreements  - The Fund may enter  into  repurchase  agreements  with
institutions that the Fund's investment adviser has determined are creditworthy.
Each  repurchase  agreement  is recorded  at cost.  The Fund  requires  that the
securities purchased in a repurchase transaction be transferred to the custodian
in a manner  sufficient  to enable the Fund to obtain  those  securities  in the
event of a default under the repurchase agreement. The Fund monitors, on a daily
basis,  the  value of the  securities  transferred  to  ensure  that the  value,
including accrued interest, of the securities under each repurchase agreement is
greater than amounts owed to the Fund under each such repurchase agreement.

Written  Options  - The Fund may write  covered  call or put  options  for which
premiums  are received and are  recorded as  liabilities,  and are  subsequently
adjusted to the current  value of the options  written.  Premiums  received from
writing  options which expire are treated as realized gains.  Premiums  received
from writing  options which are  exercised or are closed are offset  against the
proceeds or amount paid on the  transaction  to determine  the realized  gain or
loss.  If a put option is exercised,  the premium  reduces the cost basis of the
securities  purchased by the Fund. The Fund, as writer of an option, may have no
control over whether the  underlying  securities may be sold (call) or purchased
(put) and, as a result,  bears the market risk of an  unfavorable  change in the
price of the securities underlying the written option.

<PAGE>
NOTES  TO  FINANCIAL  STATEMENTS - continued
Futures  Contracts - The Fund may enter into financial futures contracts for the
delayed delivery of securities, currency or contracts based on financial indices
at a fixed price on a future  date.  In  entering  such  contracts,  the Fund is
required to deposit  either in cash or  securities  an amount equal to a certain
percentage of the contract amount.  Subsequent  payments are made or received by
the Fund  each day,  dependent  on the  daily  fluctuations  in the value of the
underlying  security,  and are  recorded  for  financial  statement  purposes as
unrealized  gains or losses by the Fund.  The  Fund's  investment  in  financial
futures  contracts is designed to hedge against  anticipated  future  changes in
interest or exchange  rates or  securities  prices.  The Fund may also invest in
financial  futures  contracts  for  non-hedging  purposes.  Should  interest  or
exchange rates or securities prices move unexpectedly,  the Fund may not achieve
the anticipated  benefits of the financial  futures  contracts and may realize a
loss.

Investment Transactions and Income - Investment transactions are recorded on the
trade date.  Interest  income is recorded on the accrual basis.  All premium and
original issue  discount are amortized or accreted for both financial  statement
and tax  reporting  purposes  as  required  by federal  income tax  regulations.
Interest  payments  received  in  additional  securities  are  recorded  on  the
ex-interest date in an amount equal to the value of the security on such date.

The Fund  has  approximately  60.8%  of its  portfolio  invested  in  high-yield
securities rated below investment  grade.  Investments in high-yield  securities
are accompanied by a greater degree of credit risk and the risk tends to be more
sensitive to economic conditions than that of higher-rated securities.

The Fund uses the effective  interest  method for reporting  interest  income on
payment-in-kind  (PIK) bonds,  whereby  interest income on PIK bonds is recorded
ratably  by the Fund at a  constant  yield to  maturity.  Legal  fees and  other
related expenses  incurred to preserve and protect the value of a security owned
are added to the cost of the security;  other legal fees are  expensed.  Capital
infusions, which are generally non-recurring, incurred to protect or enhance the
value of  high-yield  debt  securities,  are reported as an addition to the cost
basis of the  security.  Costs  that are  incurred  to  negotiate  the  terms or
conditions  of capital  infusions  or that are  expected  to result in a plan of
reorganization  are  considered  workout  expenses  and are reported as realized
losses.  Ongoing  costs  incurred to protect or enhance an  investment  or costs
incurred to pursue  other  claims or legal  actions,  are  reported as operating
expenses.

Tax  Matters  and  Distributions  - The  Fund's  policy  is to  comply  with the
provisions  of the  Internal  Revenue  Code (the Code)  applicable  to regulated
investment  companies and to distribute to  shareholders  all of its net income,
including any net realized gain on  investments.  Accordingly,  no provision for
federal income or excise tax is provided.  The Fund files a tax return  annually
using tax accounting  methods  required  under  provisions of the Code which may
differ from generally accepted accounting  principles,  the basis on which these
financial  statements  are prepared.  Accordingly,  the amount of net investment
income and net realized gain reported on these  financial  statements may differ
from that reported on the Fund's tax return and, consequently,  the character of
distributions  to shareholders  reported in the financial  highlights may differ
from that reported to  shareholders  on Form 1099-DIV.  Accumulated net realized
loss  on  investments  is  different  for  tax  purposes   because  of  deferred
recognition  of tax losses  occurring  after October 31st of the current  fiscal
year.
<PAGE>
NOTES  TO  FINANCIAL  STATEMENTS - continued
Distributions  paid  by the  Fund  from  net  interest  received  on  tax-exempt
municipal  bonds are not includable by  shareholders as gross income for federal
income tax purposes because the Fund intends to meet certain requirements of the
Code applicable to regulated investment companies, which will enable the Fund to
pay exempt-interest  dividends.  The portion of such interest, if any, earned on
private  activity  bonds  issued  after  August  7,  1986  may be  considered  a
tax-preference item to shareholders.  Distributions to shareholders are recorded
on the ex-dividend date.

The Fund  distinguishes  between  distributions  on a tax basis and a  financial
reporting  basis and  requires  that only  distributions  in excess of tax basis
earnings and profits are  reported in the  financial  statements  as a return of
capital.  Differences in the recognition or classification of income between the
financial  statements  and tax  earnings  and profits  which result in temporary
over-distributions   for  financial  statement   purposes,   are  classified  as
distributions  in excess of net investment  income or  accumulated  net realized
gains.  During the year ended January 31, 1995,  accumulated  undistributed  net
investment income was increased by $2,314,690, accumulated net realized loss was
increased  by  $2,311,955  and paid-in  capital was  decreased  by $2,735 due to
differences  between book and tax accounting  for income  recognition on certain
bonds and  differences in the cost of  securities.  This change had no effect on
the net assets or net asset value per share.

Multiple Classes of Shares of Beneficial Interest - The Fund offers both Class A
and Class B shares. Class B shares were first offered to the public on September
7, 1993. The two classes of shares differ in their shareholder  servicing agent,
distribution  and service  fees.  Shareholders  of each class also bear  certain
expenses that pertain only to that particular  class. All shareholders  bear the
common expenses of the Fund pro rata, without distinction between share classes.
Dividends  are declared  separately  for each class.  No class has  preferential
dividend  rights;  differences  in per share dividend rates are generally due to
differences in separate class expenses,  including  distribution and shareholder
service fees.

(3) Transactions  with  Affiliates
Investment  Adviser  - The  Fund  has  an  investment  advisory  agreement  with
Massachusetts  Financial  Services  Company (MFS) to provide overall  investment
advisory  and  administrative  services,  and  general  office  facilities.  The
management fee,  computed daily and paid monthly at an effective  annual rate of
0.30% of  average  daily net  assets  and  4.75% of gross  income,  amounted  to
$6,385,098  for the year ended January 31, 1995.  The Fund pays no  compensation
directly  to its  Trustees  who are  officers  of the  investment  adviser or to
officers of the Fund, all of whom receive remuneration for their services to the
Fund from MFS. Certain of the officers and Trustees of the Fund are officers and
directors of MFS, MFS Fund  Distributors,  Inc.  (MFD,  previously  known as MFS
Financial  Services,  Inc.) and MFS Service Center, Inc. (MFSC). The Fund has an
unfunded defined benefit plan for all of its independent  Trustees.  Included in
Trustees' compensation is a net periodic pension expense of $15,016 for the year
ended January 31, 1995.

Distributor - MFD, a wholly owned  subsidiary of MFS, as  distributor,  received
$1,576,774  as its portion of the sales charge on sales of Class A shares of the
Fund. The Trustees have adopted a distribution  plan relating  solely to Class B
shares pursuant to Rule 12b-1 of the Investment Company Act of 1940 as follows:

The  Class B  Distribution  Plan  provides  that the Fund will pay MFD a monthly
distribution fee, equal to 0.75% per annum, and a quarterly service fee of up to
0.25% per annum, of the Fund's average daily net assets  attributable to Class B
shares.  MFD will pay to  securities  dealers that enter into a sales  agreement
with MFD,  all or a portion of the service fee  attributable  to Class B shares.
The service fee is intended to be additional consideration for services rendered
by the  dealer  with  respect  to  Class  B  shares.  Fees  incurred  under  the
distribution  plan during the year ended  January 31, 1995 were 1.00% of average
daily net assets attributable to Class B shares and amounted to $335,495.

A contingent  deferred  sales charge is imposed on  shareholder  redemptions  of
Class A shares,  on  purchases  of $1 million  or more,  in the event of a share
redemption within 12 months following the share purchase.  A contingent deferred
sales  charge is imposed  on  shareholder  redemptions  of Class B shares in the
event of a share  redemption  within six years of  purchase.  MFD  receives  all
contingent  deferred sales charges.  Contingent  deferred sales charges  imposed
during the year ended January 31, 1995 were $57,796 for Class B shares.

<PAGE>
NOTES  TO  FINANCIAL  STATEMENTS - continued
Shareholder  Servicing  Agent - MFSC, a wholly owned  subsidiary of MFS,  earned
$1,221,491  and  $73,810 for Class A and Class B shares,  respectively,  for its
services  as  shareholder  servicing  agent.  The fee  for  Class  A  shares  is
calculated as 0.15% of the first $500 million and 0.12% of the next $500 million
of the  average  daily net  assets  of the  Fund.  The fee for Class B shares is
calculated as 0.22% of the first $500 million and 0.18% of the next $500 million
of the average daily net assets of the Fund.

(4) Portfolio  Securities
Purchases  and  sales  of  investments,   other  than  short-term   obligations,
aggregated $535,519,780 and $294,793,737, respectively.

The cost and unrealized appreciation or depreciation in value of the investments
owned by the Fund, as computed on a federal income tax basis, are as follows:

Aggregate cost                                               $1,005,158,171

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

At January 31, 1995, the Fund,  for federal  income tax purposes,  had a capital
loss  carryforward of $68,805,964,  which may be applied against any net taxable
realized gains of each  succeeding  year until the earlier of its utilization or
expiration  on January 31,  1998  ($2,344,797),  January 31, 1999  ($2,433,909),
January 31, 2000 ($4,786,449),  January 31, 2001 ($5,199,093),  January 31, 2002

with  a  bank  which  permits  borrowings  up  to  $300  million,  collectively.
Borrowings  may be made to temporarily  finance the  acquisition of Fund shares.
Interest is charged to each fund,  based on its  borrowings,  at a rate equal to
the bank's base rate. In addition,  a commitment fee, based on the average daily
unused portion of the line of credit, is allocated among the participating funds
at the end of each  quarter.  The  commitment  fee allocated to the Fund for the
year ended January 31, 1995 was $16,879.

REPORT  OF  ERNST  &  YOUNG  LLP,  INDEPENDENT  AUDITORS
To the Trustees of MFS Series Trust III and  Shareholders  of MFS Municipal High
Income Fund:

We have  audited the  accompanying  statement of assets and  liabilities  of MFS
Municipal High Income Fund, including the schedule of portfolio investments,  as
of January 31, 1995, and the related  statements of  operations,  changes in net
assets  and  financial  highlights  for the year  then  ended.  These  financial
statements  and  financial  highlights  are  the  responsibility  of the  Fund's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements and financial highlights based on our audit. The financial statements
of MFS Municipal  High Income Fund for the year ended January 31, 1994,  and the
financial  highlights for each of the nine years in the period ended January 31,
1994 for Class A shares, and for the period from September 7, 1993 (commencement
of  operations)  to January 31, 1994 for Class B shares,  were  audited by other
auditors whose report dated March 16, 1994  expressed an unqualified  opinion on
those statements and financial highlights.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we plan and perform the audit to obtain reasonable
assurance  about whether the financial  statements and financial  highlights are
free of material  misstatement.  An audit includes  examining,  on a test basis,
evidence supporting the amounts and disclosures in the financial statements. Our
procedures included  confirmation of securities owned as of January 31, 1995, by
correspondence  with the custodian and brokers or by other appropriate  auditing
procedures where replies from brokers were not received.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  the financial  statements and financial  highlights referred to
above present fairly, in all material  respects,  the financial  position of MFS
Municipal  High  Income  Fund as of January  31,  1995,  and the  results of its
operations,  the changes in its net assets, and the financial highlights for the
year then ended, in conformity with generally accepted accounting principles.

                                                           /s/ Ernst & Young LLP

         WHEREAS,  the Trust was established  pursuant to a Declaration of Trust

         WHEREAS,  the Trustees desire that the beneficial interest in the trust

(without par value) issued in one or more series, as hereinafter provided; and

in accordance with the provisions of the Declaration; and

                                   ARTICLE II
                                    TRUSTEES

         Section 2.1 - Number of Trustees.  The number of Trustees shall be such
number as shall be fixed from time to time by a written  instrument  signed by a
majority of the Trustees,  provided,  however, that the number of Trustees shall
in no event be less than three (3) nor more than fifteen (15).

         Section 2.2 - Election and Term.  Except for the Trustees  named herein
or  appointed  to fill  vacancies  pursuant to Section 2.4 hereof,  the Trustees
shall be elected by the Shareholders at the annual meeting of the  Shareholders.
Commencing in 1979 there shall be an annual  meeting of the  Shareholders  to be
held at such time and place and in such  manner as the  By-Laws  shall  provide.
Except in the event of resignations  or removal  pursuant to Section 2.3 hereof,
each Trustee shall hold office until the next annual meeting of Shareholders and
until his successor is elected and qualified to serve as Trustee.

         Section 2.3 - Resignation and Removal. Any Trustee may resign his trust
(without  need for prior or subsequent  accounting)  by an instrument in writing
signed by him and delivered to the other Trustees and such resignation  shall be
effective upon such  delivery,  or at a later date according to the terms of the
instrument. Any of the Trustees may be removed (provided the aggregate number of
Trustees  after  such  removal  shall not be less than the  number  required  by
Section 2.1 hereof) with cause,  by the action of  two-thirds  of the  remaining
Trustees. Upon the resignation or removal of a Trustee, or his otherwise ceasing
to be a Trustee,  he shall  execute and deliver such  documents as the remaining
Trustees  shall  require  for the  purpose  of  conveying  to the  Trust  or the
remaining  Trustees  any Trust  Property  held in the name of the  resigning  or
removed  Trustee.  Upon  the  incapacity  or  death of any  Trustee,  his  legal
representative  shall  execute and deliver on his behalf such  documents  as the
remaining Trustees shall require as provided in the preceding sentence.

         Section  2.4 -  Vacancies.  The  term  of  office  of a  Trustee  shall
terminate  and a vacancy  shall  occur in the event of the  death,  resignation,
removal, bankruptcy, adjudicated incompetence or other incapacity to perform the
duties of the office of a Trustee.  No such vacancy  shall  operate to annul the
Declaration or to revoke any existing  agency  created  pursuant to the terms of
the  Declaration.  In the  case of an  existing  vacancy,  including  a  vacancy
existing  by reason of an  increase  in the number of  Trustees,  subject to the
provisions of Section 16(a) of the 1940 Act, the remaining  Trustees  shall fill
such vacancy by the appointment of such other person as they in their discretion
shall  see  fit,  made by a  written  instrument  signed  by a  majority  of the
Trustees.  Any such appointment shall not become effective,  however,  until the
person named in the written  instrument  of  appointment  shall have accepted in
writing such  appointment  and agreed in writing to be bound by the terms of the
Declaration.  An  appointment  of a  Trustee  may be made in  anticipation  of a
vacancy  to  occur at a later  date by  reason  of  retirement,  resignation  or
increase in the number of Trustees,  provided  that such  appointment  shall not
become effective prior to such retirement, resignation or increase in the number
of Trustees.  Whenever a vacancy in the number of Trustees  shall  occur,  until
such  vacancy is filled as provided in this Section 2.4, the Trustees in office,
regardless  of their number,  shall have all the powers  granted to the Trustees
and shall discharge all the duties imposed upon the Trustees by the Declaration.
A written  instrument  certifying  the  existence  of such  vacancy  signed by a
majority of the Trustees  shall be conclusive  evidence of the existence of such
vacancy.

         Section 2.5 - Reallocation of Power to Other Trustees. Any Trustee may,
by power of  attorney,  delegate  his power for a period not  exceeding  six (6)
months at any one time to any other  Trustee or  Trustees;  provided  that in no
case shall less than two (2) Trustees  personally exercise the powers granted to
the  Trustees  under  the  Declaration  except  as  herein  otherwise  expressly
provided.

                                  ARTICLE III
                               POWERS OF TRUSTEES

         Section 3.1 - General.  The Trustees  shall have exclusive and absolute
control  over the Trust  Property and over the business of the Trust to the same
extent  as if the  Trustees  were the sole  owners  of the  Trust  Property  and
business  in their own  right,  but with such  powers  of  delegation  as may be
permitted  by the  Declaration.  The  Trustees  shall have power to conduct  the
business of the Trust and carry on its operations in any and all of its branches
and maintain offices both within and without The Commonwealth of  Massachusetts,
in any and all  states of the  United  States of  America,  in the  District  of
Columbia, and in any and all commonwealths, territories, dependencies, colonies,
possessions,  agencies or  instrumentalities of the United States of America and
of foreign  governments,  and to do all such other  things and  execute all such
instruments  as the  Trustees  deem  necessary,  proper or desirable in order to
promote  the  interests  of the  Trust  although  such  things  are  not  herein
specifically mentioned.  Any determination as to what is in the interests of the
Trust made by the Trustees in good faith shall be conclusive.  In construing the
provisions of the Declaration,  the presumption  shall be in favor of a grant of
power to the Trustees.

         The  enumeration of any specific power herein shall not be construed as
limiting  the  aforesaid  power.  Such powers of the  Trustees  may be exercised
without order of or resort to any court.

         Section 3.2 - Investments.  The Trustees shall have the power to:

         (a) conduct,  operate  and  carry  on  the  business  of  an investment
company;

         (b) subscribe  for,  invest in,  reinvest  in,  purchase or  otherwise
acquire, own, hold, pledge, sell, assign, transfer,  exchange,  distribute, lend
or  otherwise  deal in or  dispose  of  securities  of every  nature  and  kind,
including,   without  limitation,  all  types  of  bonds,  debentures,   stocks,
negotiable   or   non-negotiable   instruments,    obligations,   evidences   of
indebtedness,   certificates  of  deposit  or  indebtedness,  commercial  paper,
repurchase agreements,  bankers' acceptances,  and other securities of any kind,
issued,  created,  guaranteed  or sponsored  by any and all Persons,  including,
without limitation, states, territories and possessions of the United States and
the  District of Columbia  and any of the  political  subdivisions,  agencies or
instrumentalities  thereof,  and by the United  States  Government,  any foreign
government,    political    subdivisions    thereof   or   their   agencies   or
instrumentalities, or international instrumentalities, or by any bank or savings
institution, or by any corporation organized under the laws of the United States
or of  any  state,  territory  or  possession  thereof,  or by  any  corporation
organized  under any foreign  law, or in "when  issued"  contracts  for any such
securities,  or retain  Trust  assets in cash and from time to time  change  the
investments  of the assets of the Trust;  and to  exercise  any and all  rights,
powers and  privileges  of  ownership or interest in respect of any and all such
investments of every kind and description,  including,  without limitation,  the
right to consent and otherwise act with respect thereto, with power to designate
one or more persons, firms, associations or corporations to exercise any of said
rights, powers and privileges in respect of any of said instruments.

         The Trustees shall not be limited to investing in obligations  maturing
before the possible  termination of the Trust, nor shall the Trustees be limited
by any law limiting the investments which may be made by fiduciaries.

         Section 3.3 - Legal Title.  Legal title to all the Trust Property shall
be vested in the Trustees as joint tenants  except that the Trustees  shall have
power to cause legal title to any Trust Property to be held by or in the name of
one or more of the Trustees,  or in the name of the Trust, or in the name of any
other Person or nominee, on such terms as the Trustees may determine. The right,
title  and  interest  of  the  Trustees  in  the  Trust   Property   shall  vest
automatically  in each  Person  who may  hereafter  become a  Trustee.  Upon the
resignation,  removal or death of a Trustee he shall automatically cease to have
any right, title or interest in any of the Trust Property,  and the right, title
and interest of such Trustee in the Trust Property shall vest  automatically  in
the remaining  Trustees.  Such vesting and cessation of title shall be effective
whether or not conveyancing documents have been executed and delivered.

         Section 3.4 - Issuance and Repurchase of Securities. The Trustees shall
have the power to issue, sell,  repurchase,  redeem,  retire,  cancel,  acquire,
hold, resell,  reissue,  dispose of, transfer, and otherwise deal in Shares and,
subject to the  provisions  set forth in Articles  VII,  VIII and IX hereof,  to
apply  to  any  such  repurchase,   redemption,   retirement,   cancellation  or
acquisition  of Shares any funds or  property  of the Trust  whether  capital or
surplus or otherwise,  to the full extent now or hereafter permitted by the laws
of The Commonwealth of Massachusetts governing business corporations.

         Section 3.5 - Borrowing Money; Lending Trust Assets. The Trustees shall
have power to borrow money or otherwise  obtain credit and to secure the same by
mortgaging,  pledging or  otherwise  subjecting  as  security  the assets of the
Trust,  to endorse,  guarantee,  or undertake the performance of any obligation,
contract or engagement of any other Person and to lend Trust assets.

         Section 3.6 - Delegation;  Committees. The Trustees shall have power to
delegate from time to time to such of their number or to officers,  employees or
agents  of the  Trust  the  doing  of  such  things  and the  execution  of such
instruments  either  in the name of the Trust or the  names of the  Trustees  or
otherwise as the Trustees may deem expedient.

         Section 3.7 - Collection and Payment.  The Trustees shall have power to
collect  all  property  due to the Trust;  to pay all claims,  including  taxes,
against the Trust  Property;  to  prosecute,  defend,  compromise or abandon any
claims  relating to the Trust  Property;  to  foreclose  any  security  interest
securing any obligations, by virture of which any property is owed to the Trust;
and to enter into releases, agreements and other instruments.

         Section 3.8 - Expenses.  The Trustees shall have the power to incur and
pay  any  expenses  which  in the  opinion  of the  Trustees  are  necessary  or
incidental  to carry  out any of the  purposes  of the  Declaration,  and to pay
reasonable  compensation  from the funds of the Trust to themselves as Trustees.
The Trustees shall fix the compensation of all officers, employees and Trustees.

         Section 3.9 - Manner of Acting;  By-Laws.  Except as otherwise provided
herein or in the By-Laws, any action to be taken by the Trustees may be taken by
a majority of the  Trustees  present at a meeting of  Trustees  (a quorum  being
present),  including any meeting held by means of a conference telephone circuit
or similar communications  equipment by means of which all persons participating
in the meeting can hear each other, or by written  consents of all the Trustees.
The Trustees may adopt By-Laws not inconsistent with this Declaration to provide
for the  conduct  of the  business  of the Trust  and may  amend or repeal  such
By-Laws to the extent such power is not reserved to the Shareholders.

         Section 3.10 - Miscellaneous Powers.  The Trustees shall have the power
to:

         (a) employ  or  contract  with such Persons as  the Trustees  may  deem
desirable  for the  transaction  of the business of the Trust;

         (b) enter  into  joint  ventures,   partnerships and any other combina-
tions or associations;

         (c) remove Trustees or fill vacancies in or add to their number,  elect
and remove such officers and appoint and  terminate  such agents or employees as
they consider appropriate, and appoint from their own number, and terminate, any
one or more committees which may exercise some or all of the power and authority
of the Trustees as the Trustees may determine;

         (d) purchase,  and pay for out of Trust  Property,  insurance  policies
insuring the Shareholders,  Trustees,  officers,  employees,  agents, investment
advisers, distributors, selected dealers or independent contractors of the Trust

not constituting negligence, or whether or not the Trust would have the power to
indemnify such Person against such liability;

         Section 3.11 - Principal Transactions. Except in transactions permitted
by the 1940  Act,  or any  order of  exemption  issued  by the  Commission,  the

counsel, registrar,  transfer agent, dividend disbursing agent or custodian upon
customary terms.

         Section  3.12 -  Trustees  and  Officers  as  Shareholders.  Except  as

         Section 4.1 -  Investment  Adviser.  Subject to a Majority  Shareholder
Vote,  the  Trustees  may in their  discretion  from time to time  enter into an
investment  advisory  or  management  contract  whereby  the other party to such
contract  shall  undertake  to  furnish  the Trust such  management,  investment
advisory,   statistical  and  research  facilities  and  services,   promotional
activities,  and such other  facilities  and  services,  if any, as the Trustees
shall  from  time  to time  consider  desirable  and all  upon  such  terms  and
conditions as the Trustees may in their discretion determine notwithstanding any
provisions  of the  Declaration,  the Trustees  may  delegate to the  Investment
Adviser  authority  (subject  to such  general or specific  instructions  as the
Trustees  may from  time to time  adopt) to effect  purchases,  sales,  loans or
exchanges of portfolio  securities of the Trust on behalf of the Trustees or may
authorize  any  officer,  employee or Trustee to effect such  purchases,  sales,
loans or exchanges  pursuant to  recommendations  of the Investment Adviser (and
all without further action by the Trustees).  Any such purchases,  sales,  loans
and exchanges shall be deemed to have been authorized by all of the Trustees.

         Section 4.2 - Distributor.  The Trustees may in their  discretion  from
time to time enter into a contract, providing for the sale of Shares whereby the
Trust may either  agree to sell the Shares to the other party to the contract or
appoint  such other party its sales agent for such Shares.  In either case,  the
contract  shall be on such terms and  conditions  as the  Trustees  may in their
discretion  determine not inconsistent with the provisions of this Article IV or
the By-Laws;  and such  contract may also provide for the  repurchase or sale of
Shares by such other party as principal or as agent of the Trust and may provide
that such other party may enter into selected dealer  agreements with registered
securities  dealers to further the purpose of the  distribution or repurchase of
the Shares.

         Section 4.3 - Transfer Agent. The Trustees may in their discretion from
time to time enter  into a transfer  agency  and  shareholder  service  contract
whereby the other party to such  contract  shall  undertake to furnish  transfer

inconsistent with the Declaration or the By-Laws.  Such services may be provided
by one or more Persons.

         Section  4.4 - Parties  to  Contract.  Any  contract  of the  character
described  in  Section  4.1,  4.2 or 4.3 of  this  Article  IV or any  Custodian

although one or more of the Trustees or officers of the Trust may be an officer,
partner, director,  trustee,  shareholder,  or member of such other party to the
contract,  and no such contract  shall be  invalidated  or rendered  voidable by
reason of the existence of any such  relationship;  nor shall any Person holding
such  relationship be liable merely by reason of such  relationship for any loss
or expense to the Trust under or by reason of said contract or  accountable  for

the By-Laws.  The same Person may be the other party to  contracts  entered into
pursuant to Sections  4.1,  4.2 and 4.3 above or  Custodian  contracts,  and any
individual may be financially  interested or otherwise  affiliated  with Persons
who are parties to any or all of the contracts mentioned in this Section 4.4.

                                   ARTICLE V
         LIMITATIONS OF LIABILITY OF SHAREHOLDERS, TRUSTEES AND OTHERS

         Section 5.1 - No Personal Liability of Shareholders,  Trustees, etc. No
Shareholder shall be subject to any personal liability  whatsoever to any Person
in connection  with Trust  Property or the acts,  obligations  or affairs of the
Trust. No Trustee,  officer,  employee or agent of the Trust shall be subject to
any personal  liability  whatsoever  to any Person,  other than the Trust or its
Shareholders,  in  connection  with Trust  Property or the affairs of the Trust,
save only that arising from bad faith, willful misfeasance,  gross negligence or
reckless  disregard for his duty to such Person; and all such Persons shall look
solely to the Trust Property for satisfaction of claims of any nature arising in
connection with the affairs of the Trust. If any Shareholder,  Trustee, officer,
employee,  or  agent,  as  such,  of the  Trust,  is made a party to any suit or
proceeding to enforce any such liability,  he shall not, on account thereof,  be
held to any  personal  liability.  The  Trust  shall  indemnify  and  hold  each
Shareholder harmless from and against all claims and liabilities,  to which such
Shareholder  may  become  subject  by  reason  of his  being  or  having  been a
Shareholder,  and  shall  reimburse  such  Shareholder  for all  legal and other
expenses  reasonably  incurred  by him in  connection  with  any  such  claim or
liability. The rights accruing to a Shareholder under this Section 5.1 shall not
exclude any other right to which such Shareholder may be lawfully entitled,  nor
shall anything herein contained  restrict the right of the Trust to indemnify or
reimburse  a  Shareholder   in  any   appropriate   situation  even  though  not
specifically provided herein.

         Section 5.2 -  Non-Liability  of  Trustees,  etc. No Trustee,  officer,
employee or agent of the Trust shall be liable to the Trust,  its  Shareholders,
or to any  Shareholder,  Trustee,  officer,  employee,  or agent thereof for any
action or failure to act (including  without limitation the failure to compel in
any way any former or acting  Trustee to redress any breach of trust) except for
his own bad faith, willful  misfeasance,  gross negligence or reckless disregard
of his duties.

         Section 5.3 - Mandatory Indemnification.

         (a)    Subject to the exceptions and limitations contained in paragraph
(b) below:

                (i) every  person who is or has been a Trustee or officer of the
Trust shall be  indemnified  by the Trust  against all liability and against all
expenses  reasonably  incurred  or paid by him in  connection  with  any  claim,
action,  suit or proceeding in which he becomes involved as a party or otherwise
by virtue of his being or having been a Trustee or officer  and against  amounts
paid or incurred by him in the settlement thereof;

                (ii) the words "claim,"  "action," "suit," or "proceeding" shall
apply to all claims,  actions,  suits or proceedings (civil,  criminal or other,
including  appeals),  actual  or  threatened,  and  the  words  "liability"  and
"expenses" shall include, without limitation, attorneys' fees, costs, judgments,
amounts paid in settlement, fines, penalties and other liabilities.

         (b)    No indemnification shall be  provided  hereunder to a Trustee or
officer:

                (i) against any  liability to the Trust or the  Shareholders  by
reason of a final  adjudication  by the  court or other  body  before  which the
proceeding was brought that he engaged in willful misfeasance,  bad faith, gross
negligence  or reckless  disregard of the duties  involved in the conduct of his
office;

                (ii) with  respect  to any matter as to which he shall have been
finally  adjudicated  not to have acted in good faith in the  reasonable  belief
that his action was in the best interests of the Trust;

                iii )in  the  event of a  settlement  or other  disposition  not
involving  a final  adjudication  as  provided  in  paragraph  (b)(i) or (b)(ii)
resulting  in a payment by a Trustee or officer,  unless there has been either a
determination   that  such   Trustee  or  officer  did  not  engage  in  willful
misfeasance,  bad faith,  gross  negligence or reckless  disregard of the duties
involved in the conduct of his office by the court or other body  approving  the
settlement  or other  disposition  or a reasonable  determination,  based upon a
review of readily available facts (as opposed to a full trial-type inquiry) that
he did not engage in such conduct:

                     (A)  by vote of a majority  of the  Disinterested  Trustees
acting on the matter  (provided that a majority  of  the  Disinterested Trustees
then in office act on the matter); or

                     (B) by written opinion of independent legal counsel.

         (c) The  rights  of  indemnification  herein  provided  may be  insured
against by  policies  maintained  by the Trust,  shall be  severable,  shall not
affect any other  rights to which any Trustee or officer may now or hereafter be
entitled,  shall  continue  as to a Person who has ceased to be such  Trustee or
officer  and  shall  inure  to  the   benefit  of  the  heirs,   executors   and
administrators of such Person.  Nothing contained herein shall affect any rights
to  indemnification  to which  personnel other than Trustees and officers may be
entitled by contract or otherwise under law.

         (d) Expenses of preparation and presentation of a defense to any claim,
action,  suit or proceeding of the character  described in paragraph (a) of this
Section 5.3 shall be advanced  by the Trust prior to final  disposition  thereof
upon receipt of an  undertaking  by or on behalf of the  recipient to repay such
amount if it is ultimately determined that he is not entitled to indemnification
under this Section 5.3, provided that either:

                (i) such  undertaking  is secured by a surety bond or some other
appropriate security or the Trust shall be insured against losses arising out of
any such advances; or

                (ii) a  majority  of the  Disinterested  Trustees  acting on the
matter  (provided that a majority of the  Disinterested  Trustees then in office
act on the matter) or an independent  legal counsel in a written opinion,  shall
determine,  based upon a review of readily available facts (as opposed to a full
trial-type  inquiry),  that  there is  reason  to  believe  that  the  recipient
ultimately will be found entitled to indemnification.

         As used in this Section 5.3, a  "Disinterested  Trustee" is one (i) who
is not an  "Interested  Person"  of the  Trust  (including  anyone  who has been
exempted from being an "Interested  Person" by any rule,  regulation or order of
the  Commission),  and (ii)  against whom none of such  actions,  suits or other
proceedings or another action,  suit or other  proceeding on the same or similar
grounds is then or had been pending.

         Section  5.4 - No Bond  Required  of  Trustees.  No  Trustee  shall  be
obligated to give any bond or other  security for the  performance of any of his
duties hereunder.

         Section 5.5 - No Duty of  Investigation;  Notice in Trust  Instruments,
etc. No  purchaser,  lender,  transfer  agent or other  Person  dealing with the
Trustees or any  officer,  employee or agent of the Trust shall be bound to make
any inquiry concerning the validity of any transaction  purporting to be made by
the  Trustees  or by said  officer,  employee  or  agent  or be  liable  for the
application of money or property paid,  loaned,  or delivered to or on the order
of the  Trustees  or of said  officer,  employee  or  agent.  Every  obligation,
contract,  instrument,  certificate,  Share,  other  security  of the  Trust  or
undertaking, and every other act or thing whatsoever executed in connection with
the Trust shall be  conclusively  presumed to have been  executed or done by the
executors thereof only in their capacity as Trustees under the Declaration or in
their  capacity as  officers,  employees or agents of the Trust.  Every  written
obligation,  contract,  instrument,  certificate,  Share,  other security of the
Trust or  undertaking  made or issued by the Trustees shall recite that the same
is  executed  or  made by them  not  individually,  but as  Trustees  under  the
Declaration,  and that the  obligations  of any such  instrument are not binding
upon any of the Trustees or Shareholders,  individually, but bind only the trust
estate,  and  may  contain  any  further  recital  which  they  or he  may  deem
appropriate,  but the omission of such recital  shall not operate to bind any of
the Trustees  individually.  The Trustees shall at all times maintain  insurance
for the protection of the Trust Property, its Shareholders,  Trustees, officers,
employees and agents in such amount as the Trustees shall deem adequate to cover
possible tort liability,  and such other insurance as the Trustees in their sole
judgment shall deem advisable.

         Section  5.6 - Reliance on Experts,  etc.  Each  Trustee and officer or
employee of the Trust  shall,  in the  performance  of his duties,  be fully and
completely  justified and protected with regard to any act or any failure to act
resulting from reliance in good faith upon the books of account or other records
of the Trust,  upon an opinion of counsel,  or upon reports made to the Trust by
any of its officers or employees or by the Investment Adviser,  the Distributor,
Transfer Agent,  selected dealers,  accountants,  appraisers or other experts or
consultants selected with reasonable care by the Trustees, officers or employees
of the  Trust,  regardless  of  whether  such  counsel  or expert  may also be a
Trustee.

                                   ARTICLE VI
                         SHARES OF BENEFICIAL INTEREST

         Section 6.1 - Beneficial  Interest.  The interest of the  beneficiaries
hereunder  shall be divided into  transferable  Shares of  beneficial  interest,
without  par  value.  The  number of Shares of  beneficial  interest  authorized
hereunder  is  unlimited.   All  Shares  issued  hereunder  including,   without
limitation,  Shares issued in connection with a dividend in Shares or a split of
Shares, shall be fully paid and non-assessable.

         Section  6.2 - Rights  of  Shareholders.  The  ownership  of the  Trust
property of every description and the right to conduct any business hereinbefore
described are vested  exclusively in the Trustees,  and the  Shareholders  shall
have no interest therein other than the beneficial  interest  conferred by their
Shares,  and they shall have no right to call for any  partition  or division of
any property,  profits,  rights or interests of the Trust nor can they be called
upon to assume  any losses of the Trust or suffer an  assessment  of any kind by
virtue of their  ownership  of Shares.  The Shares  shall be  personal  property
giving only the rights in the  Declaration  specifically  set forth.  The Shares
shall not entitle the holder to preference, preemptive, appraisal, conversion or
exchange rights,  except as the Trustees may determine with respect to any class
of Shares.

         Section 6.3 - Trust Only. It is the intention of the Trustees to create
only the  relationship of Trustee and beneficiary  between the Trustees and each
Shareholder from time to time. It is not the intention of the Trustees to create
a  general   partnership,   limited   partnership,   joint  stock   association,
corporation,  bailment  or any form or legal  relationship  other  than a trust.
Nothing in the Declaration shall be construed to make the  Shareholders,  either
by  themselves  or with the  Trustees,  partners  or  members  of a joint  stock
association.

         Section 6.4 - Issuance of Shares.  The  Trustees,  in their  discretion
may,  from time to time  without  vote of the  Shareholders,  issue  Shares,  in
addition  to the then  issued and  outstanding  Shares  and  Shares  held in the
treasury,   to  such  party  or  parties   and  for  such  amount  and  type  of
consideration,  including cash or property,  at such time or times,  and on such
terms as the Trustees may deem best, and may in such manner acquire other assets
(including  the  acquisition  of assets  subject to, and in connection  with the
assumption of liabilities)  and  businesses.  In connection with any issuance of
Shares,  the Trustees may issue fractional Shares. The Trustees may from time to
time divide or combine the Shares of any series into a greater or lesser  number
without thereby changing the  proportionate  beneficial  interests in the Trust.
Contributions to the Trust may be accepted for, and Shares shall be redeemed as,
whole Shares and/or 1/1,000ths of a Share or integral multiples thereof.

         Section  6.5 -  Register  of Shares.  A  register  shall be kept at the
principal  office of the Trust or at an office of the Transfer Agent which shall
contain the names and  addresses  of the  Shareholders  and the number of Shares
held by them respectively and a record of all transfers  thereof.  Such register
shall be  conclusive  as to who are the  holders  of the Shares and who shall be
entitled to receive dividends or distributions or otherwise to exercise or enjoy
the rights of Shareholders.  No Shareholder shall be entitled to receive payment
of any dividend or distribution, nor to have notice given to him as herein or in
the By-Laws  provided,  until he has given his address to the Transfer  Agent or
such other  officer or agent of the Trustees as shall keep the said register for
entry thereon. The Trustees, in their discretion,  may authorize the issuance of
Share certificates and promulgate  appropriate rules and regulations as to their
use.

         Section 6.6 - Transfer of Shares.  Shares shall be  transferable on the
records of the Trust only by the record holder thereof or by his agent thereunto
duly authorized in writing,  upon delivery to the Trustees or the Transfer Agent
of a duly executed  instrument of transfer,  together  with any  certificate  or
certificates (if issued) for such Shares and such evidence of the genuineness of
each such execution and  authorization and of other matters as may reasonably be
required.  Upon such delivery the transfer  shall be recorded on the register of
the Trust.  Until such record is made, the Shareholder of record shall be deemed
to be the holder of such  Shares for all  purposes  hereunder  and  neither  the
Trustees nor any Transfer Agent or registrar nor any officer,  employee or agent
of the Trust shall be affected by any notice of the proposed transfer.

         Any person  becoming  entitled to any Shares in  consequence  of death,
bankruptcy,  or  incompetence of any  Shareholder,  or otherwise by operation of
law,  shall be recorded  on the  register of Shares as the holder of such Shares
upon production of the proper  evidence  thereof to the Trustees or the Transfer
Agent;  but until such record is made, the Shareholder of record shall be deemed
to be the holder of such  Shares for all  purposes  thereunder  and  neither the
Trustees  nor any Transfer  Agent or  registrar  nor any officer of agent of the
Trust shall be affected by any notice of such death, bankruptcy or incompetence,
or other operation of law.

         Section 6.7 - Notices. Any and all notices to which any Shareholder may
be entitled and any and all communications  shall be deemed duly served or given
if mailed,  postage prepaid,  addressed to any Shareholder of record at his last
known address as recorded on the register of the Trust.

         Section 6.8 - Voting Powers.  The Shareholders shall have power to vote
only (i) for the election of Trustees as provided in Section 2.2.  hereof,  (ii)
with respect to any  investment  advisory or management  contract as provided in
Section  4.1.,  (iii) with  respect to  termination  of the Trust as provided in
Section  9.2.,  (iv) with  respect to any  amendment of the  Declaration  to the
extent  and as  provided  in  Section  9.3.,  (v) with  respect  to any  merger,
consolidation  or sale of assets as provided in Sections 9.4., (vi) with respect
to  incorporation  of the Trust to the extent and as provided  in Section  9.5.,
(vii)  to the  same  extent  as the  stockholders  of a  Massachusetts  business
corporation  as to whether or not a court action,  proceeding or claim should or
should not be brought or maintained  derivatively or as a class action on behalf
of the Trust of the  Shareholders,  and (viii) with  respect to such  additional
matters relating to the Trust as may be required by the Declaration, the By-Laws
or any  registration of the Trust with the Commission (or any successor  agency)
or any state, or as the Trustees may consider necessary or desirable. Each whole
Share  shall be entitled to one vote as to any matter on which it is entitled to
vote and each fractional  Share shall be entitled to a proportionate  fractional
vote,  except  that the Shares  held in the  treasury  of the Trust shall not be
voted.  There shall be no cumulative  voting in the election of Trustees.  Until
Shares are issued,  the Trustees may exercise all rights of Shareholders and may
take any action  required by law, the  Declaration or the By-Laws to be taken by
Shareholders. The By-Laws may include further provisions for Shareholders' votes
and meetings and related matters.

         Section 6.9 - Series  Designation.  The Trustees,  in their discretion,
may authorize the division of Shares into two or more series,  and the different
series shall be established and  designated,  and the variations in the relative
rights  and  preferences  as between  the  different  series  shall be fixed and
determined by the Trustees;  provided, that all Shares shall be identical except
that there may be variations so fixed and determined between different series as
to  purchase  price,  right of  redemption  and the  price,  terms and manner of
redemption,  special and  relative  rights as to dividends  and on  liquidation,
conversion  rights,  and  conditions  under which the several  series shall have
separate  voting rights.  Any series of Shares may be terminated by the Trustees
by written notice to shareholders of the series.

         The  series of  Shares  established  and  designated  pursuant  to this
Section 6.9 and existing as of the date hereof are set forth in Annex A hereto.

         Section  6.10  -  Class   Designation.   The  Trustees  may,  in  their
discretion,  authorize the division of Shares of the Trust (or any series of the
Trust) into one or more classes.  All Shares of a class shall be identical  with
each  other  and with the  Shares of each  other  class of the Trust or the same
series of the Trust (as applicable),  except for such variations between classes
as may be  approved by the Board of Trustees  and  permitted  by the 1940 Act or
pursuant  to  any  exemptive   order  issued  by  the  Securities  and  Exchange
Commission.  The classes of Shares authorized  pursuant to this Section 6.10 and
existing as of the date hereof are set forth in Annex B hereto.

                                  ARTICLE VII
                                  REDEMPTIONS

         Section 7.1 - Redemptions.  In case any Shareholder at any time desires
to dispose  of his  Shares,  he may  deposit  his  certificate  or  certificates
therefor,  duly  endorsed in blank or  accompanied  by an instrument of transfer
executed in blank, or if the Shares are not represented by any  certificates,  a
written  request or other such form of request as the  Trustees may from time to
time authorize, at the office of the Transfer Agent or at the office of any bank
or trust company,  either in or outside of  Massachusetts,  which is a member of
the Federal  Reserve  System and which the said Transfer Agent has designated in
writing for that  purpose,  together with an  irrevocable  offer in writing in a
form  acceptable to the Trustees to sell the Shares  represented  thereby to the
Trust at the net asset value  thereof per Share,  determined  as provided in the
By-Laws,  next after such deposit.  Payment for said Shares shall be made to the
Shareholder  within  seven (7) days after the date on which the deposit is made,
unless (i) the date of payment is postponed  pursuant to Section 7.2 hereof,  or
(ii) the receipt,  or  verification  of receipt,  of the purchase  price for the
Shares to be  redeemed  is  delayed,  in either of which  event  payment  may be
delayed beyond seven (7) days.

         Section 7.2 - Suspension of Right of Redemption.  The Trust may declare
a  suspension  of the right of  redemption  or  postpone  the date of payment or
redemption for the whole or any part of any period (i) during which the New York
Stock  Exchange is closed other than  customary  week-end and holiday  closings,
(ii) during which trading on the New York Stock  Exchange is  restricted,  (iii)
during which an emergency  exists as a result of which  disposal by the Trust of
securities  owned by it is not  reasonably  practicable  or it is not reasonably
practicable  for the Trust fairly to determine  the value of its net assets,  or
(iv)  during any other  period when the  Commission  may for the  protection  of
security  holders  of the  Trust  by order  permit  suspension  of the  right of
redemption or postponement  of the date of payment or redemption;  provided that
applicable  rules and  regulations of the Commission  shall govern as to whether
the conditions  prescribed in (ii),  (iii) or (iv) exist.  Such suspension shall
take effect at such time as the Trust shall specify but not later than the close
of business on the business day next  following the  declaration  of suspension,
and  thereafter  there shall be no right of  redemption or payment on redemption
until  the  Trust  shall  declare  the  suspension  at an end,  except  that the
suspension  shall  terminate  in any event on the first day on which  said stock
exchange shall have reopened or the period specified in (ii) or (iii) shall have
expired (as to which,  in the absence of an official  ruling by the  Commission,
the determination of the Trust shall be conclusive). In the case of a suspension
of the right of redemption,  a Shareholder  may either  withdraw his request for
redemption or receive  payment based on the net asset value  existing  after the
termination of the suspension.

         Section 7.3 -  Redemption  of Shares;  Disclosure  of  Holding.  If the
Trustees  shall, at any time and in good faith, be of the opinion that direct or
indirect  ownership of Shares or other securities of the Trust has or may become
concentrated  in any Person to an extent which would  disqualify  the Trust as a
regulated  investment company under the Internal Revenue Code, then the Trustees
shall have the power by lot or other means deemed  equitable by them (i) to call
for redemption by any such Person a number,  or principal  amount,  of Shares or
other  securities  of the Trust  sufficient  to  maintain or bring the direct or
indirect  ownership of Shares or other  securities of the Trust into  conformity
with the requirements for such  qualification  and (ii) to refuse to transfer or
issue Shares or other securities of the Trust to any Person whose acquisition of
the Shares or other  securities  of the Trust in question  would  result in such
disqualification.  The redemption  shall be effected at the redemption price and
in the manner provided in Section 7.1.

         The  holders  of Shares or other  securities  of the Trust  shall  upon
demand  disclose to the  Trustees in writing  such  information  with respect to
direct and indirect  ownership of Shares or other securities of the Trust as the
Trustees deem  necessary to comply with the  provisions of the Internal  Revenue
Code, or to comply with the requirements of any other authority.

         Section 7.4 - Redemption in Kind. Payment for Shares deposited pursuant
to Section 7.1 may, at the option of the  Trustees,  or such officer or officers
as they may duly authorize for the purpose, in their complete discretion be made
in cash,  or in kind,  or  partially in cash and  partially in kind.  In case of
payment in kind, the Trustees, or their delegate, shall have absolute discretion
as to what security or securities shall be distributed in kind and the amount of
the same, and the securities shall be valued for purposes of distribution at the
figure at which they were  appraised in computing the asset value of the Shares,
provided  that  any  Shareholder  who  cannot  legally  acquire   securities  so
distributed in kind by reason of the  prohibitions of the 1940 Act shall receive
cash.

                                  ARTICLE VIII
         DETERMINATION OF NET ASSET VALUE, NET INCOME AND DISTRIBUTIONS

         The Trustees, in their absolute discretion, may prescribe and shall set
forth in the  By-Laws  such  bases and times for  determining  the per Share net
asset  value of the Shares or net  income,  or the  declaration  and  payment of
dividends and distributions, as they may deem necessary or desirable.

                                   ARTICLE IX
            DURATION; TERMINATION OF TRUST; AMENDMENT; MERGERS, ETC.

         Section 9.1 - Duration.  The Trust shall continue without limitation of
time but subject to the provisions of this Article IX.

         Section 9.2 - Termination of Trust.

         (a) The  Trust may be  terminated  (i) by the  affirmative  vote of the
holders of not less than  two-thirds of the Shares  outstanding  and entitled to
vote at any  meeting  of  Shareholders,  or (ii) by an  instrument  in  writing,
without a meeting,  signed by a majority of the Trustees and consented to by the
holders of not less than two-thirds of such Shares,  or (iii) by the Trustees by
written notice to the Shareholders. Upon the termination of the Trust:

                (i)  the Trust shall carry on no business except for the purpose
of winding up its affairs;

                (ii) the  Trustees  shall  proceed to wind up the affairs of the
Trust  and all of the  powers  of the  Trustees  under  this  Declaration  shall
continue until the affairs of the Trust shall have been wound up,  including the
power to fulfill or discharge  the  contracts of the Trust,  collect its assets,
sell, convey, assign, exchange, transfer or otherwise dispose of all or any part
of the remaining Trust Property to one or more persons at public or private sale
for consideration  which may consist in whole or in part of cash,  securities or
other  property of any kind,  discharge  or pay its  liabilities,  and to do all
other acts  appropriate  to liquidate  its  business;  provided,  that any sale,
conveyance,  assignment,  exchange,  transfer  or  other  disposition  of all or
substantially  all the Trust  Property  shall  require  Shareholder  approval in
accordance with Section 9.4 hereof; and

               (iii) after paying or adequately providing for the payment of all
liabilities,  and upon  receipt  of such  releases,  indemnities  and  refunding
agreements  as they  deem  necessary  for their  protection,  the  Trustees  may
distribute the remaining  Trust  Property,  in cash or in kind or partly in cash
and partly in kind, among the Shareholders according to their respective rights.

         (b) After termination of the Trust and distribution to the Shareholders
as herein provided, a majority of the Trustees shall execute and lodge among the
records of the Trust an  instrument  in writing  setting  forth the fact of such
termination,  and the Trustees  shall  thereupon be discharged  from all further
liabilities  and  duties  hereunder,   and  the  rights  and  interests  of  all
Shareholders shall thereupon cease.

         Section 9.3 - Amendment Procedure.

         (a) This  Declaration may be amended by a Majority  Shareholder Vote or
by any  instrument  in writing,  without a meeting,  signed by a majority of the
Trustees  and  consented  to by the  holders of not less than a majority  of the
Shares  outstanding  and  entitled  to vote.  The  Trustees  may also amend this
Declaration  without the vote or consent of  Shareholders  to change the name of
the Trust, to supply any omission, to cure, correct or supplement any ambiguous,
defective  or  inconsistent  provision  hereof,  or if they deem it necessary to
conform this  Declaration  to the  requirements  of  applicable  federal laws or
regulations or the requirements of the regulated  investment  company provisions
of the Internal  Revenue Code,  but the Trustees shall not be liable for failing
so to do.

         (b) No amendment  may be made under this Section 9.3 which would change
any rights with  respect to any Shares by reducing  the amount  payable  thereon
upon liquidation of the Trust or by diminishing or eliminating any voting rights
pertaining thereto, except with the vote or consent of the holders of two-thirds
of the Shares  outstanding  and  entitled  to vote.  Nothing  contained  in this
Declaration  shall  permit  the  amendment  of this  Declaration  to impair  the
exemption  from  personal  liability of the  Shareholders,  Trustees,  officers,
employees and agents of the Trust or to permit assessments upon Shareholders.

         (c) A certificate signed by a majority of the Trustees setting forth an
amendment  and reciting that it was duly adopted by the  Shareholders  or by the
Trustees as aforesaid or a copy of the Declaration,  as amended, and executed by
a majority of the Trustees,  shall be conclusive evidence of such amendment when
lodged among the records of the Trust.

         Notwithstanding  any  other  provision  hereof,  until  such  time as a
Registration  Statement  under the Securities Act of 1933, as amended,  covering
the  first  public  offering  of  securities  of the  Trust  shall  have  become
effective,  this  Declaration may be terminated or amended in any respect by the
affirmative  vote of a majority of the Trustees or by an instrument  signed by a
majority of the Trustees.

         Section 9.4 - Merger,  Consolidation and Sale of Assets.  The Trust may
merge or consolidate  with any other  corporation,  association,  trust or other
organization  or may sell,  lease or exchange  all or  substantially  all of the
Trust Property,  including its good will, upon such terms and conditions and for
such consideration when and as authorized at any meeting of Shareholders  called
for  the  purpose  by the  affirmative  vote of the  holders  of not  less  than
two-thirds of the Shares  outstanding  and entitled to vote, or by an instrument
or instruments in writing without a meeting,  consented to by the holders of not
less than  two-thirds of such Shares;  provided,  however,  that if such merger,
consolidation,  sale, lease or exchange is recommended by the Trustees, the vote
or written  consent  of the  holders of a  majority  of Shares  outstanding  and
entitled  to vote  shall  be  sufficient  authorization;  and any  such  merger,
consolidation,  sale, lease or exchange shall be deemed for all purposes to have
been  accomplished  under and  pursuant to the statutes of The  Commonwealth  of
Massachusetts.

         Section  9.5 -  Incorporation.  With the  approval  of the holders of a
majority of the Shares  outstanding and entitled to vote, the Trustees may cause
to be organized or assist in organizing a corporation or corporations  under the
laws of any jurisdiction, or any other trust, partnership,  association or other
organization  to take over all of the Trust Property or to carry on any business
in which the Trust shall directly or indirectly have any interest,  and to sell,
convey  and  transfer  the  Trust  Property  to  any  such  corporation,  trust,
association or organization in exchange for the Shares or securities  thereof or
otherwise,  and to lend money to, subscribe for the Shares or securities of, and
enter  into  any  contracts  with  any  such  corporation,  trust,  partnership,
association or organization or any corporation,  partnership, trust, association
or  organization  in which the Trust holds or is about to acquire  Shares of any
other interest.  The Trustees may also cause a merger or  consolidation  between
the Trust or any successor thereto and any such corporation, trust, partnership,
association  or other  organization  if and to the extent  permitted  by law, as
provided  under  the law  then in  effect.  Nothing  contained  herein  shall be
construed as requiring  approval of Shareholders for the Trustees to organize or
assist  in  organizing   one  or  more   corporations,   trusts,   partnerships,
associations  or other  organizations  and selling,  conveying or transferring a
portion of the Trust Property to such organization or entitles.

                                   ARTICLE X
                            REPORTS TO SHAREHOLDERS

         The Trustees shall at least semi-annually  submit to the Shareholders a
written financial report of the transactions of the Trust,  including  financial
statements  which shall at least  annually be  certified by  independent  public
accountants.

                                   ARTICLE XI
                                 MISCELLANEOUS

         Section 11.1 - Filing.  This Declaration and any amendment hereto shall
be filed in the office of the Secretary of The Commonwealth of Massachusetts and
in such other places as may be required under the laws of Massachusetts  and may
also be filed or recorded in such other places as the Trustees deem appropriate.
Each  amendment  so filed  shall be  accompanied  by a  certificate  signed  and
acknowledged  by a Trustee  stating  that such action was duly taken in a manner
provided  herein,  and unless such amendment or such certificate sets forth some
later time for the  effectiveness  of such  amendment,  such amendment  shall be
effective upon its filing.  A restated  Declaration,  integrating  into a single
instrument all of the provisions of the Declaration which are then in effect and
operative,  may be executed  from time to time by a majority of the Trustees and
shall, upon filing with the Secretary of The Commonwealth of  Massachusetts,  be
conclusive  evidence of all amendments  contained  therein and may thereafter be
referred  to in lieu of the  original  Declaration  and the  various  amendments
thereto.

         Section  11.2 -  Governing  Law.  This  Declaration  is executed by the
Trustees and delivered in The Commonwealth of  Massachusetts  and with reference
to the  laws  thereof,  and the  rights  of all  parties  and the  validity  and
construction  of every  provision  hereof  shall  be  subject  to and  construed
according to the laws of said State.

         Section 11.3 - Counterparts.  This  Declaration  may be  simultaneously
executed  in  several  counterparts,  each of  which  shall be  deemed  to be an
original,  and such  counterparts,  together,  shall constitute one and the same
instrument,   which  shall  be  sufficiently  evidenced  by  any  such  original
counterpart.

         Section 11.4 - Reliance by Third Parties.  Any certificate  executed by
an individual who, according to the records of the Trust appears to be a Trustee
hereunder,   certifying   to:  (a)  the  number  or   identity  of  Trustees  or
Shareholders,  (b) the due  authorization  of the execution of any instrument or
writing,  (c)  the  form  of  any  vote  passed  at a  meeting  of  Trustees  or
Shareholders,  (d) the fact that the number of Trustees or Shareholders  present
at any meeting or executing any written instrument satisfies the requirements of
this Declaration,  (e) the form of any By-Laws adopted by or the identity of any
officers  elected by the  Trustees,  or (f) the  existence  of any fact or facts
which in any manner  relate to the  affairs of the  Trust,  shall be  conclusive
evidence as to the matters so certified in favor of any Person  dealing with the
Trustees and their successors.

         Section 11.5 - Provisions in Conflict with Law or Regulations.

         (a)  The  provisions  of  the  Declaration  are  severable,  and if the
Trustees  shall  determine,  with  the  advice  of  counsel,  that  any of  such
provisions is in conflict with the 1940 Act, the  regulated  investment  company
provisions  of the  Internal  Revenue  Code or with  other  applicable  laws and
regulations, the conflicting provision shall be deemed never to have constituted
a part of the Declaration;  provided, however, that such determination shall not
affect any of the remaining  provisions of the  Declaration or render invalid or
improper any action taken or omitted prior to such determination.

         (b) If any  provision  of the  Declaration  shall  be held  invalid  or
unenforceable in any  jurisdiction,  such invalidity or  unenforceability  shall
attach only to such provision in such  jurisdiction  and shall not in any manner
affect such provision in any other  jurisdiction  or any other  provision of the
Declaration in any jurisdiction.

                                    ANNEX A

         Pursuant to Section 6.9 of the  Declaration,  the Trustees of the Trust
have  established  and  designated  two  series of  Shares  (as  defined  in the
Declaration), such series to have the following special and relative rights:

             1.       The series are designated:
                      -      MFS High Income Fund
                      -      MFS Municipal High Income Fund

             2.       The  series  shall  be   authorized  to  invest  in  cash,
                      securities, instruments and other property as from time to
                      time  described  in the Trust's then  currently  effective
                      registration statement under the Securities Act of 1933 to
                      the extent  pertaining  to the  offering of Shares of such
                      series.  Each  Share of the  series  shall be  redeemable,
                      shall be  entitled  to one  vote or  fraction  thereof  in
                      respect of a  fractional  share on matters on which Shares
                      of the series shall be entitled to vote, shall represent a
                      pro rata  beneficial  interest in the assets  allocated or
                      belonging to the series,  and shall be entitled to receive
                      its pro rata share of the net  assets of the  series  upon
                      liquidation of the series,  all as provided in Section 6.9
                      of the Declaration.

             3.       Shareholders  of the  series  shall vote  separately  as a
                      class on any  matter to the  extent  required  by, and any
                      matter shall be deemed to have been effectively acted upon
                      with  respect to the series as provided in Rule 18f-2,  as
                      from time to time in effect,  under the Investment Company
                      Act of 1940, as amended, or any successor rule, and by the
                      Declaration.

             4.       The assets and liabilities of the Trust shall be allocated
                      among the  established and existing series of the Trust as
                      set forth in Section 6.9 of the Declaration.

             5.       Subject to the provisions of Section 6.9 and Article IX of
                      the  Declaration,  the Trustees  (including  any successor
                      Trustees)  shall  have the right at any time and from time
                      to time to reallocate assets and expenses or to change the
                      designation of any series now or hereafter created,  or to
                      otherwise  change the special and  relative  rights of any
                      such series.
<PAGE>

              "Class B Shares";

              Class B Shares,  and the  relative  dividend  rights of holders of
              Class A Shares  and  Class B Shares  shall be  established  by the
              Trustees of the Trust in accordance with the Declaration and shall
              be set forth in the current prospectus and statement of additional
              information  of the Trust or any series  thereof,  as amended from
              time to time,  contained  in the  Trust's  registration  statement
              under the Securities Act of 1933, as amended.

         4.   Class A Shares and Class B Shares shall vote  together as a single
              class except that Shares of a class may vote separately on matters
              affecting  only that class and Shares of a class not affected by a
              matter will not vote on that matter.

         5.   A class of Shares of any series of the Trust may be  terminated by
              the Trustees by written notice to the Shareholders of the class.


         Pursuant to Section 6.10 of the Declaration of the Trust,  the Trustees
have divided the Shares of the MFS High Income  Fund, a series of the Trust,  to
create three classes of Shares, within the meaning of Section 6.10, as follows:

              entitled  to all the rights  and  preferences  accorded  to Shares
              under the Declaration of Trust;

         3.   The purchase  price of Class A Shares,  Class B Shares and Class C
              Shares,  the  method of  determination  of the net asset  value of
              Class A Shares,  Class B Shares  and Class C  Shares,  the  price,
              terms and manner of redemption  of Class A Shares,  Class B Shares
              and Class C Shares,  any conversion feature of Class B Shares, and
              the relative dividend rights of holders of Class A Shares, Class B
              Shares and Class C Shares shall be  established by the Trustees of
              the Trust in accordance with the Declaration of Trust and shall be
              set forth in the current  prospectus  and  statement of additional
              information  of the Trust or any series  thereof,  as amended from
              time to time,  contained  in the  Trust's  registration  statement
              under the Securities Act of 1933, as amended;

         4.   Class A  Shares,  Class B Shares  and  Class C Shares  shall  vote
              together as a single  class except that Shares of a class may vote
              separately  on matters  affecting  only that class and Shares of a
              class not affected by a matter will not vote on that matter; and

                                   ARTICLE I

                                  DEFINITIONS

         The  terms  "Commission",  "Declaration",   "Distributor",  "Investment
Adviser",  "Majority  Shareholder  Vote", "1940 Act",  "Shareholder",  "Shares",
"Transfer Agent",  "Trust",  "Trust Property" and "Trustees" have the respective
meanings  given them in the  Declaration of Trust of MFS Series Trust III, dated
December 15, 1977, as amended from time to time.

                                   ARTICLE II

                                    OFFICES

         SECTION  1.  PRINCIPAL  OFFICE.  Until  changed  by the  Trustees,  the
principal office of the Trust in The  Commonwealth of Massachusetts  shall be in
the City of Boston, County of Suffolk.

         SECTION  2.  OTHER  OFFICES.  The Trust may have  offices in such other
places without as well as within the  Commonwealth as the Trustees may from time
to time determine.

                                  ARTICLE III

                                  SHAREHOLDERS

         SECTION 1. MEETINGS.  Meetings of the Shareholders may be called at any
time by a  majority  of the  Trustees  and shall be called by any  Trustee  upon
written  request  of  Shareholders  holding in the  aggregate  not less than ten
percent (10%) of the  outstanding  Shares of the Trust having voting rights,  if
shareholders  of all series are required  under the  Declaration  to vote in the
aggregate  and not by  individual  series at such  meeting,  or of any series or
class if shareholders of such series or class are entitled under the Declaration
to vote by individual  series or class,  such request  specifying the purpose or
purposes for which such meeting is to be called.  Any such meeting shall be held
within or without The Commonwealth of Massachusetts on such day and at such time
as the Trustees shall designate.

         SECTION 2. NOTICE OF MEETINGS.  Notice of all meetings of Shareholders,
stating  the time,  place and  purposes  of the  meeting,  shall be given by the
Trustees by mail to each  Shareholder  entitled  to vote at such  meeting at his
address as recorded on the register of the Trust,  mailed at least (ten) 10 days
and not more than (sixty) 60 days before the meeting.  Only the business  stated
in the notice of the meeting shall be considered at such meeting.  Any adjourned
meeting may be held as adjourned without further notice. No notice need be given
to any  Shareholder  who shall have  failed to inform  the Trust of his  current
address or if a written waiver of notice,  executed  before or after the meeting
by the  Shareholder  or his  attorney  thereunto  authorized,  is filed with the
records of the meeting.

         SECTION 3. RECORD DATE FOR MEETINGS. For the purpose of determining the
Shareholders  who are  entitled to notice of and to vote at any  meeting,  or to
participate  in any  distribution,  or for the purpose of any other action,  the
Trustees  may from time to time close the transfer  books for such  period,  not
exceeding  thirty (30) days, as the Trustees may determine;  or without  closing
the  transfer  books the  Trustees  may fix a date not more than sixty (60) days
prior to the date of any meeting of Shareholders or distribution or other action
as a  record  date  for  the  determination  of the  persons  to be  treated  as
Shareholders of record for such purpose.

         SECTION  4.  PROXIES.  At any  meeting of  Shareholders,  any holder of
Shares entitled to vote thereat may vote by proxy,  provided that no proxy shall
be voted at any meeting unless it shall have been placed on file with the Clerk,
or with such other  officer or agent of the Trust as the Clerk may  direct,  for
verification prior to the time at which such vote shall be taken.  Pursuant to a
vote of a majority of the Trustees,  proxies may be solicited in the name of one
or more Trustees or one or more of the officers of the Trust.  When any Share is
held  jointly by  several  persons,  any one of them may vote at any  meeting in
person or by proxy in respect of such Share,  but if more than one of them shall
be present at such meeting in person or by proxy, and such joint owners or their
proxies so present  disagree  as to any vote to be cast,  such vote shall not be
received in respect of such Share.  A proxy  purporting  to be executed by or on
behalf of a Shareholder  shall be deemed valid unless  challenged at or prior to
its exercise, and the burden of proving invalidity shall rest on the challenger.
The  placing  of a  Shareholder's  name on a proxy  pursuant  to  telephonic  or
electronically   transmitted   instructions   obtained  pursuant  to  procedures
reasonably  designed to verify that such  instructions  have been  authorized by
such  Shareholder  shall  constitute  execution of such proxy by or on behalf of
such  Shareholder.  If the  holder  of any such  Share is a minor or a person of
unsound mind, and subject to  guardianship  or to the legal control of any other
person as regards the charge or  management  of such  Share,  he may vote by his
guardian or such other person  appointed or having such  control,  and such vote
may be given in person or by proxy.  Any copy,  facsimile  telecommunication  or
other reliable reproduction of a proxy may be substituted for or used in lieu of
the original  proxy for any and all purposes for which the original  proxy could
be  used,  provided  that  such  copy,  facsimile   telecommunication  or  other
reproduction  shall be a complete  reproduction  of the entire original proxy or
the portion thereof to be returned by the Shareholder.

         SECTION 5.  QUORUM,  ADJOURNMENT  AND  REQUIRED  VOTE.  A  majority  of
outstanding  Shares entitled to vote shall constitute a quorum at any meeting of
Shareholders,  except that where any provision of law, the  Declaration or these
By-laws  permits or requires that holders of any series or class shall vote as a
series or  class,  then a  majority  of the  aggregate  number of Shares of that
series or class  entitled to vote shall be necessary to  constitute a quorum for
the transaction of business by that series or class. In the absence of a quorum,
a majority of outstanding Shares entitled to vote present in person or by proxy,
or, where any  provision of law, the  Declaration  or these  By-laws  permits or
requires that holders of any series or class shall vote as a series or class,  a
majority of outstanding  Shares of that series or class entitled to vote present
in person or by proxy,  may adjourn the meeting from time to time until a quorum
shall be present.  Only  Shareholders of record shall be entitled to vote on any
matter.  Each full Share  shall be entitled  to one vote and  fractional  Shares
shall be entitled to a vote of such fraction.  Except as otherwise  provided any
provision  of law, the  Declaration  or these  By-laws,  Shares  representing  a
majority of the votes cast shall decide any matter (i.e., abstentions and broker
non-votes shall not be counted) and a plurality shall elect a Trustee,  provided
that where any provision of law, the  Declaration  or these  By-Laws  permits or
requires  that  holders of any series or class  shall vote as a series or class,
then a majority of the Shares of that  series or class cast on the matter  shall
decide the matter (i.e.,  abstentions and broker non-votes shall not be counted)
insofar as that series or class is concerned.

         SECTION 6.  INSPECTION  OF  RECORDS.  The records of the Trust shall be
open  to  inspection  by  Shareholders  to  the  same  extent  as  is  permitted
shareholders of a Massachusetts business corporation.

         SECTION 7. ACTION  WITHOUT  MEETING.  Any action  which may be taken by
Shareholders  may be taken  without  a meeting  if a  majority  of  Shareholders
entitled  to vote on the matter (or such larger  proportion  thereof as shall be
required by law, the  Declaration  or these By-Laws for approval of such matter)
consent to the action in writing  and the  written  consents  are filed with the
records of the meetings of  Shareholders.  Such consent shall be treated for all
purposes as a vote taken at a meeting of Shareholders.

                                   ARTICLE IV

                                    TRUSTEES

         SECTION  1.  MEETINGS  OF THE  TRUSTEES.  The  Trustees  may  in  their
discretion  provide for regular or stated  meetings of the  Trustees.  Notice of
regular or stated  meetings  need not be given.  Meetings of the Trustees  other
than regular or stated meetings shall be held whenever called by the Chairman or
by any one of the  Trustees at the time being in office.  Notice of the time and
place of each meeting  other than regular or stated  meetings  shall be given by
the Secretary or an Assistant  Secretary,  or the Clerk or an Assistant Clerk or
by the  officer  or  Trustee  calling  the  meeting  and shall be mailed to each
Trustee at least two days before the meeting,  or shall be telegraphed,  cabled,
or wirelessed or sent by facsimile or other  electronic means to each Trustee at
his business address, or personally delivered to him at least one day before the
meeting. Such notice may, however, be waived by any Trustee. Notice of a meeting
need not be given to any Trustee if a written waiver of notice,  executed by him
before or after the meeting, is filed with the records of the meeting, or to any
Trustee  who  attends the meeting  without  protesting  prior  thereto or at its
commencement  the lack of notice to him.  A notice or waiver of notice  need not
specify the purpose of any  meeting.  Except as provided by law the Trustees may
meet by  means of a  telephone  conference  circuit  or  similar  communications
equipment  by means of which all persons  participating  in the meeting can hear
each other, which telephone conference meeting shall be deemed to have been held
at a  place  designated  by the  Trustees  at the  meeting.  Participation  in a
telephone  conference  meeting  shall  constitute  presence  in  person  at such
meeting.  Any action  required  or  permitted  to be taken at any meeting of the
Trustees  may be taken by the  Trustees  without a meeting  if all the  Trustees
consent to the action in writing  and the  written  consents  are filed with the
records of the Trustees' meetings.  Such consents shall be treated as a vote for
all purposes.

         SECTION 2.  QUORUM AND MANNER OF  ACTING.  A majority  of the  Trustees
shall be present at any regular or special  meeting of the  Trustees in order to
constitute a quorum for the  transaction of business at such meeting and (except
as otherwise  required by law, the  Declaration  or these  By-Laws) the act of a
majority  of the  Trustees  present  at any such  meeting,  at which a quorum is
present,  shall  be the act of the  Trustees.  In the  absence  of a  quorum,  a
majority of the Trustees present may adjourn the meeting from time to time until
a quorum shall be present. Notice of an adjourned meeting need not be given.

                                   ARTICLE V

                         COMMITTEES AND ADVISORY BOARD

         SECTION 1.  EXECUTIVE AND OTHER  COMMITTEES.  The Trustees by vote of a
majority  of all the  Trustees  may elect  from  their own  number an  Executive
Committee  to consist of not less than three (3)  Trustees to hold office at the
pleasure of the  Trustees  which shall have the power to conduct the current and
ordinary business of the Trust while the Trustees are not in session,  including
the purchase and sale of  securities  and the  designation  of  securities to be
delivered upon  redemption of Shares of the Trust,  and such other powers of the
Trustees as the  Trustees  may,  from time to time,  delegate  to the  Executive
Committee  except those powers which by law, the  Declaration  or these  By-Laws
they are prohibited from delegating.  The Trustees may also elect from their own
number other Committees from time to time, the number composing such Committees,
the powers  conferred  upon the same  (subject to the same  limitations  as with
respect  to the  Executive  Committee)  and  the  term  of  membership  on  such
Committees  to be  determined  by the  Trustees.  The Trustees  may  designate a
chairman of any such Committee.
In the absence of such designation a Committee may elect its own Chairman.

         SECTION 2.  MEETING, QUORUM AND MANNER OF ACTING.  The Trustees may:

                  (i)      provide for stated meetings of any Committee,

                  (ii)     specify the manner of  calling  and  notice  required
                           for  special  meetings  of any Committee,

                  (iii)    specify the number of members of a Committee required
                           to constitute a quorum and the number of members of a
                           Committee   required  to  exercise  specified  powers
                           delegated to such Committee,

                  (iv)     authorize   the  making  of   decisions  to  exercise
                           specified  powers by written  assent of the requisite
                           number of members of a  Committee  without a meeting,
                           and

                  (v)      authorize the members of a Committee to meet by means
                           of a telephone conference circuit.

         Each Committee  shall keep regular  minutes of its meetings and records
of  decisions  taken  without a meeting  and cause them to be recorded in a book
designated for that purpose and kept in the office of the Trust.

         SECTION 3. ADVISORY  BOARD.  The Trustees may appoint an Advisory Board
to consist in the first instance of not less than three (3) members.  Members of
such  Advisory  Board  shall  not  be  Trustees  or  officers  and  need  not be
Shareholders.  A member of such Advisory Board shall hold office for such period
as the Trustees may by resolution  provide.  Any member of such board may resign
therefrom  by a written  instrument  signed by him which  shall take effect upon
delivery to the  Trustees.  The  Advisory  Board shall have no legal  powers and
shall not perform the functions of Trustees in any manner,  such Advisory  Board
being intended merely to act in an advisory capacity.  Such Advisory Board shall
meet at such  times  and upon  such  notice as the  Trustees  may by  resolution
provide.

                                   ARTICLE VI

                                    OFFICERS

         SECTION 1.  GENERAL  PROVISIONS.  The  officers of the Trust shall be a
Chairman,  a  President,  a Treasurer  and a Clerk,  who shall be elected by the

Treasurers,  and one or more Assistant Clerks.  The Trustees may delegate to any

of the  Trustees.  Any two or more offices may be held by the same  person.  Any
officer may be, but none need be, a Trustee or Shareholder.

         SECTION 3. REMOVAL. The Trustees,  at any regular or special meeting of
the  Trustees,  may remove  any  officer  with or  without  cause by a vote of a
majority  of the  Trustees.  Any  officer or agent  appointed  by any officer or
Committee  may be removed with or without  cause by such  appointing  officer or
Committee.

         SECTION 4. POWERS AND DUTIES OF THE  CHAIRMAN.  The  Chairman  may call

the Trustees and any Committees of the Trustees, the Chairman shall at all times

often as they shall require the same and shall in general perform all the duties
incident to the office of  Treasurer  and such other duties as from time to time
may be assigned to him by the Trustees.  The Treasurer shall give a bond for the
faithful discharge of his duties, if required to do so by the Trustees,  in such
sum and with such surety or sureties as the Trustees shall require.

purpose; he shall have custody of the seal of the Trust; he shall have charge of

of all notices by the Trust in accordance  with the  provisions of these By-Laws
and as  required  by law;  and  subject  to these  By-Laws,  he shall in general

shall be fixed from time to time by the Trustees or, in the case of officers, by

                                  ARTICLE VII

telegraph,  cable or wireless  company with  instruction that it be telegraphed,

                                   CUSTODIAN

         SECTION 1.  APPOINTMENT  AND DUTIES.  The  Trustees  shall at all times
employ a bank or trust company having a capital,  surplus and undivided  profits
of at least five million dollars ($5,000,000) as custodian with authority as its
agent, but subject to such restrictions,  limitations and other requirements, if
any, as may be contained in the Declaration, these By-Laws and the 1940 Act:

                  (1)      to hold the securities owned by the Trust and deliver
                           the same upon written order;

                  (2)      to  receive  and  receipt  for any  monies due to the
                           Trust  and  deposit  the  same  in  its  own  banking
                           department or elsewhere as the Trustees may direct;

                  (3)      to disburse such funds upon orders or vouchers;

                  (4)      if authorized by the Trustees,  to keep the books and
                           accounts  of  the  Trust  and  furnish  clerical  and
                           accounting services; and

                  (5)      if authorized  to do so by the  Trustees,  to compute
                           the net income of the Trust;

all upon such basis of  compensation  as may be agreed upon between the Trustees
and the custodian.  If so directed by a Majority Shareholder Vote, the custodian
shall  deliver and pay over all property of the Trust held by it as specified in
such vote.

         The Trustees  may also  authorize  the  custodian to employ one or more
sub-custodians from time to time to perform such of the acts and services of the
custodian and upon such terms and conditions,  as may be agreed upon between the
custodian and such sub-custodian and approved by the Trustees,  provided that in
every case such  sub-custodian  shall be a bank or trust company organized under
the laws of the United States or one of the states  thereof and having  capital,
surplus and undivided profits of at least five million dollars ($5,000,000).

         SECTION  2.  CENTRAL  CERTIFICATE   SYSTEM.   Subject  to  such  rules,
regulations and orders as the Commission may adopt,  the Trustees may direct the
custodian to deposit all or any part of the  securities  owned by the Trust in a
system  for  the  central  handling  of  securities  established  by a  national
securities  exchange or a national  securities  association  registered with the
Commission  under the  Securities  Exchange Act of 1934, or such other person as
may be permitted by the  Commission,  or otherwise in  accordance  with the 1940
Act,  pursuant to which system all securities of any particular  class or series
of any issuer  deposited  within the system are treated as  fungible  and may be
transferred or pledged by bookkeeping  entry without  physical  delivery of such
securities,  provided that all such deposits shall be subject to withdrawal only
upon the order of the Trust or its custodian.

         SECTION 3. ACCEPTANCE OF RECEIPTS IN LIEU OF  CERTIFICATES.  Subject to
such rules, regulations and orders as the Commission may adopt, the Trustees may
direct the  custodian  to accept  written  receipts or other  written  evidences
indicating  purchases  of  securities  held in  book-entry  form in the  Federal
Reserve  System  in  accordance  with  regulations  promulgated  by the Board of
Governors of the Federal  Reserve System and the local Federal  Reserve Banks in
lieu of receipt of certificates representing such securities.

         SECTION 4. PROVISIONS OF CUSTODIAN CONTRACT.  The following  provisions
shall apply to the  employment of a custodian  pursuant to this Article X and to
any contract entered into with the custodian so employed:

                  (a)      The  Trustees  shall  cause  to be  delivered  to the
                           custodian  all  securities  owned by the  Trust or to
                           which it may  become  entitled,  and shall  order the
                           same  to be  delivered  by the  custodian  only  upon
                           completion of a sale, exchange,  transfer, pledge, or
                           other  disposition  thereof,  and upon receipt by the
                           custodian   of  the   consideration   therefor  or  a
                           certificate  of  deposit or a receipt of an issuer or
                           of  its  Transfer  Agent,  all as  the  Trustees  may
                           generally or from time to time require or approve, or
                           to a  successor  custodian;  and the  Trustees  shall
                           cause all funds owned by the Trust or to which it may
                           become  entitled  to be  paid to the  custodian,  and
                           shall order the same  disbursed  only for  investment
                           against  delivery of the securities  acquired,  or in
                           payment    of    expenses,    including    management
                           compensation, and liabilities of the Trust, including
                           distributions  to  Shareholders,  or  to a  successor
                           custodian;  provided,  however,  that nothing  herein
                           shall prevent  delivery of securities for examination
                           to the  broker  selling  the same in accord  with the
                           "street  delivery" custom whereby such securities are
                           delivered  to such broker in exchange  for a delivery
                           receipt  exchanged on the same day for an uncertified
                           check of such broker to be  presented on the same day
                           for certification.

                  (b)      In case of the  resignation,  removal or inability to
                           serve of any such custodian, the Trust shall promptly
                           appoint  another  bank or trust  company  meeting the
                           requirements   of  this   Article   X  as   successor
                           custodian.  The agreement  with the  custodian  shall
                           provide  that  the  retiring  custodian  shall,  upon
                           receipt of notice of such  appointment,  deliver  the
                           funds and property of the Trust in its  possession to
                           and  only  to  such   successor,   and  that  pending
                           appointment  of a successor  custodian,  or a vote of
                           the Shareholders to function without a custodian, the
                           custodian shall not deliver funds and property of the
                           Trust to the Trust, but may deliver them to a bank or
                           trust    company    doing    business    in   Boston,
                           Massachusetts,   of  its  own  selection,  having  an
                           aggregate capital,  surplus and undivided profits (as
                           shown  in its  last  published  report)  of at  least
                           $5,000,000,  as the  property of the Trust to be held
                           under terms  similar to those on which they were held
                           by the retiring custodian.

                                   ARTICLE XI

                          SALE OF SHARES OF THE TRUST

         The Trustees may from time to time issue and sell or cause to be issued
and sold Shares for cash or other property, which shall in every case be paid or
delivered  to the  Custodian  as agent of the Trust  before the  delivery of any
certificate for such shares. The Shares,  including  additional Shares which may
have been  repurchased by the Trust (herein  sometimes  referred to as "treasury
shares"),  may not be sold at a price less than the net asset value  thereof (as
defined in Article XII hereof)  determined  by or on behalf of the Trustees next
after the sale is made or at some later time after such sale.

         No Shares need be offered to existing Shareholders before being offered
to others.  No Shares  shall be sold by the Trust  (although  Shares  previously
contracted  to be sold may be issued upon  payment  therefor)  during any period
when the  determination  of net asset value is suspended by  declaration  of the
Trustees  pursuant to the provisions of Article XII hereof.  In connection  with
the acquisition by merger or otherwise of all or substantially all the assets of
an investment  company (whether a regulated or private  investment  company or a
personal holding  company),  the Trustees may issue or cause to be issued Shares
and accept in payment  therefor such assets valued at not more than market value
thereof in lieu of cash,  notwithstanding  that the federal  income tax basis to
the Trust of any assets so acquired may be less than the market value,  provided
that such assets are of the  character in which the  Trustees  are  permitted to
invest the funds of the Trust.

         The Trustees,  in their sole discretion,  may cause the Trust to redeem
all of the  Shares of the  Trust  held by any  Shareholder  if the value of such
Shares  is less  than a  minimum  amount  established  from  time to time by the
Trustees.


                                  ARTICLE XII

                           NET ASSET VALUE OF SHARES

         The term "net  asset  value" per Share of any class or series of Shares
shall mean: (i) the value of all assets of that series or class; (ii) less total
liabilities  of such series or class;  (iii)  divided by the number of Shares of
such  series  or  class   outstanding,   in  each  case  at  the  time  of  such
determination,  all as determine by or under the direction of the Trustees. Such
value  shall be  determined  on such days and at such time as the  Trustees  may
determine. Such determination shall be made with respect to securities for which
market quotations are readily available, at the market value of such securities;
and with respect to other securities and assets, at the fair value as determined
in good  faith  by or  pursuant  to the  direction  of the  Trustees,  provided,
however, that the Trustees,  without shareholder approval,  may alter the method
of appraising  portfolio securities insofar as permitted under the 1940 Act, and
the rules,  regulations and interpretations thereof promulgated or issued by the
Securities  and Exchange  Commission or insofar as permitted by any order of the
Securities  and  Exchange  commission.  The Trustees may delegate any powers and
duties  under  this  Article  XII  with  respect  to  appraisal  of  assets  and
liabilities.  At any time the  Trustees  may cause  the  value  per  share  last
determined to be determined  again in a similar manner and may fix the time when
such predetermined value shall become effective.

                                  ARTICLE XIII

                          DIVIDENDS AND DISTRIBUTIONS

         SECTION 1. LIMITATIONS ON DISTRIBUTIONS.  The total of distributions to
Shareholders  of a particular  series or class paid in respect of any one fiscal
year, subject to the exceptions noted below,  shall, when and as declared by the
Trustees, be approximately equal to the sum of:

                  (i)      the net  income,  exclusive  of the profits or losses
                           realized   upon  the  sale  of  securities  or  other
                           property,  of such  series or class  for such  fiscal
                           year,   determined  in  accordance   with   generally
                           accepted   accounting   principles   (which,  if  the
                           Trustees  so  determine,  may  be  adjusted  for  net
                           amounts  included  as such  accrued net income in the
                           price of  Shares of such  series  or class  issued or
                           repurchased), but if the net income of such series or
                           class exceeds the amount distributed by less than one
                           cent per share outstanding at the record date for the
                           final  dividend,  the  excess  shall  be  treated  as
                           distributable  income of such series or class for the
                           following fiscal year; and

                  (ii)     in the  discretion  of the  Trustees,  an  additional
                           amount  which  shall  not  substantially  exceed  the
                           excess of profits over losses on sales of  securities
                           or other  property  allocated  or  belonging  to such
                           series or class for such fiscal year.

The decision of the Trustees as to what, in accordance  with generally  accepted
accounting  principles,  is income  and what is  principal  shall be final,  and
except as  specifically  provided herein the decision of the Trustees as to what
expenses and charges of the Trust shall be charged  against  principal  and what
against income shall be final,  all subject to any applicable  provisions of the
1940  Act and  rules,  regulations  and  orders  of the  Commission  promulgated
thereunder. For the purposes of the limitation imposed by this Section 1, Shares
issued  pursuant to Section 2 of this Article XIII shall be valued at the amount
of cash  which the  Shareholders  would  have  received  if they had  elected to
receive cash in lieu of such Shares.

         Inasmuch as the  computation of net income and gains for federal income
tax  purposes  may vary from the  computation  thereof on the  books,  the above
provisions  shall be  interpreted  to give to the  Trustees  the  power in their
discretion  to  distribute  for any fiscal  year as  ordinary  dividends  and as
capital gains  distributions,  respectively,  additional  amounts  sufficient to
enable the Trust to avoid or reduce  liability  for taxes.  Any payment  made to
Shareholders pursuant to clause (ii) of this Section 1 shall be accompanied by a
written statement  showing the source or sources of such payment,  and the basis
of computation thereof.

         SECTION 2. DISTRIBUTIONS  PAYABLE IN CASH OR SHARES. The Trustees shall
have power, to the fullest extent  permitted by the laws of The  Commonwealth of
Massachusetts but subject to the limitation as to cash distributions  imposed by
Section 1 of this Article  XIII, at any time or from time to time to declare and
cause to be paid distributions payable at the election of any Shareholder of any
series  or class  (whether  exercised  before or after  the  declaration  of the
distribution) either in cash or in Shares of such series,  provided that the sum
of:

                  (i)      the   cash   distribution   actually   paid   to  any
                           Shareholder, and

                  (ii)     the  net  asset  value  of  the  Shares   which  that
                           Shareholder elects to receive, in effect at such time
                           at or after the election as the Trustees may specify,
                           shall  not  exceed  the full  amount of cash to which
                           that  Shareholder  would be entitled if he elected to
                           receive only cash.

In the case of a  distribution  payable in cash or Shares at the  election  of a
Shareholder,  the  Trustees  may  prescribe  whether a  Shareholder,  failing to
express his election before a given time shall be deemed to have elected to take
Shares rather than cash,  or to take cash rather then Shares,  or to take Shares
with cash adjustment of fractions.

         The Trustees, in their sole discretion,  may cause the Trust to require
that all distributions payable to a shareholder in amounts less than such amount
or  amounts  determined  from  time to time by the  Trustees  be  reinvested  in
additional  shares of the Trust rather than paid in cash,  unless a  shareholder
who, after  notification that his distributions will be reinvested in additional
shares  in  accordance  with  the  preceding  phrase,  elects  to  receive  such
distributions in cash. Where a shareholder has elected to receive  distributions
in cash and the postal or other delivery  service is unable to deliver checks to
the shareholder's address of record, the Trustees, in their sole discretion, may
cause the Trust to require that such Shareholder's  distribution  option will be
converted to having all distributions reinvested in additional shares.

         SECTION 3. STOCK  DIVIDENDS.  Anything in these By-Laws to the contrary
notwithstanding,  the Trustees may at any time declare and  distribute  pro rata
among the  Shareholders of any series or class a "stock  dividend" out of either
authorized  but  unissued  Shares of such series or class or treasury  Shares of
such series or class or both.

                                  ARTICLE XIV

                               DERIVATIVE CLAIMS

         No  Shareholder  shall  have the right to bring or  maintain  any court
action,  proceeding  or claim on  behalf  of the  Trust or any  series  or class
thereof  without first making demand on the Trustees  requesting the Trustees to
bring or maintain such action, proceeding or claim. Such demand shall be excused
only when the plaintiff makes a specific showing that irreparable  injury to the
Trust or any series or class thereof would otherwise  result.  Such demand shall
be mailed to the Clerk of the Trust at the  Trust's  principal  office and shall
set  forth in  reasonable  detail  the  nature  of the  proposed  court  action,
proceeding or claim and the essential  facts relied upon by the  Shareholder  to
support the  allegations  made in the demand.  The Trustees  shall consider such
demand within 45 days of its receipt by the Trust. In their sole discretion, the
Trustees  may submit the  matter to a vote of  Shareholders  of the Trust or any
series or class thereof, as appropriate.  Any decision by the Trustees to bring,
maintain  or settle (or not to bring,  maintain  or settle)  such court  action,
proceeding or claim, or to submit the matter to a vote of Shareholders, shall be
made by the  Trustees in their  business  judgment and shall be binding upon the
Shareholders.  Any decision by the Trustees to bring or maintain a court action,
proceeding  or suit on behalf of the Trust or any series or class  thereof shall
be subject to the right of the Shareholders under Article VI, Section 6.8 of the
Declaration  to vote on  whether or not such court  action,  proceeding  or suit
should or should not be brought or maintained.

                                   ARTICLE XV

                                   AMENDMENTS


                  These  By-Laws,  or any  of  them, may be altered,  amended or
repealed, or new By-Laws may be adopted

                  (a) by Majority Shareholder Vote, or

                  (b) by the Trustees,

provided,  however,  that no By-Law may be  amended,  adopted or repealed by the
Trustees if such amendment,  adoption or repeal  requires,  pursuant to law, the
Declaration or these By-Laws,  a vote of the  Shareholders or if such amendment,
adoption  or repeal  changes or affects  the  provisions  of Sections 1 and 4 of
Article X or the provisions of this Article XV.




                                                   
                                                             EXHIBIT NO. 99.5(a)



                         INVESTMENT ADVISORY AGREEMENT



         THIS  AGREEMENT,  made  this  20th  day of May,  1987,  by and  between
MASSACHUSETTS  FINANCIAL HIGH INCOME TRUST, a Massachusetts  business trust (the
"Fund") and MASSACHUSETTS  FINANCIAL  SERVICES COMPANY,  a Delaware  corporation
(the "Adviser").

                                  WITNESSETH:

         WHEREAS,  the Fund is engaged in  business  as an  open-end  investment
company registered under the Investment Company Act of 1940;

         WHEREAS, the Adviser is willing to provide business management services
to the Fund on the terms and conditions hereinafter set forth;

         WHEREAS,  the Fund is composed  of two Series,  Series I and Series II,
and terms for the  provision  of advisory  services  have been  established  for
Series I pursuant to an agreement  between the Fund and the  Adviser,  dated May
20, 1982;

         WHEREAS,  the Fund  wishes  to  establish  terms for the  provision  of
advisory to Series II of the Fund (the "Series") services hereby;

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
of the parties  hereto as herein set forth,  the parties  covenant  and agree as
follows:

         ARTICLE 1: DUTIES OF THE ADVISER.  The Adviser shall provide the Series
with such investment  advice and supervision as the latter may from time to time
consider necessary for the proper management of its funds. The Adviser shall act
as Adviser to the Series and as such shall  furnish  continuously  an investment
program  and  shall  determine  from  time  to time  what  securities  shall  be
purchased,  sold or exchanged and what portion of the assets of the Series shall
be held  uninvested,  subject always to the  restrictions  of the Declaration of
Trust of the Fund,  dated December 15, 1977,  and By-Laws,  each as amended from
time to time  (respectively,  the "Declaration"  and the "By-Laws"),  and to the
provisions of the  Investment  Company Act of 1940.  The Adviser shall also make
recommendations  as to the manner in which voting  rights,  rights to consent to
corporate  action  and any other  rights  pertaining  to the  Series'  portfolio
securities shall be exercised.  Should the Trustees at any time,  however,  make
any definite  determination  as to the investment  policy and notify the Adviser
thereof in writing,  the Adviser  shall be bound by such  determination  for the
period, if any,  specified in such notice or until similarly  notified that such
determination has been revoked. The Adviser shall take, on behalf of the Series,
all actions  which it deems  necessary  to  implement  the  investment  policies
determined  as provided  above,  and in  particular  to place all orders for the
purchase or sale of portfolio securities for the Series' account with brokers or
dealers  selected by it, and to that end the Adviser is  authorized as the agent
of the Fund to give  instructions  to the Custodian of the Fund as to deliveries
of securities and payments of cash for the account of the Series.  In connection
with the  selection  of such  brokers or dealers and the placing of such orders,
the Adviser is directed to seek for the Series the most favorable  execution and
price.  After fulfilling this primary  requirement of seeking for the Series the
most favorable  execution and price, the Adviser is hereby expressly  authorized
to consider, subject to any applicable laws, rules and regulations, statistical,
research  and other  information  or  services  furnished  to the Adviser or the
Series.

         ARTICLE 2:  ALLOCATION  OF CHARGES  AND  EXPENSES.  The  Adviser  shall
furnish at its own expense all necessary administrative services,  office space,
equipment  and  clerical  personnel,  and  investment  advisory  facilities  and
executive and supervisory personnel for managing the investments,  effecting the
portfolio transactions,  and in general administering the affairs of the Series.
The Adviser shall arrange,  if desired by the Fund, for Directors,  officers and
employees of the Adviser to serve as Trustees, officers or agents of the Fund if
duly  elected or  appointed to such  positions  and subject to their  individual
consent and to any  limitations  imposed by law. It is understood  that the Fund
will pay all of its own expenses including, without limitation,  compensation of
Trustees not affiliated with the Adviser,  governmental fees,  interest charges,
taxes,  membership  dues in the Investment  Company  Institute  allocable to the
Fund,  fees and expenses of  independent  auditors,  of legal counsel and of any
transfer agent, registrar and dividend disbursing agent of the Fund, expenses of
repurchasing and redeeming shares,  expenses of preparing,  printing and mailing
share  certificates,   prospectuses,   shareholders'  reports,   notices,  proxy
statements and reports to governmental  officers and commissions,  brokerage and
other expenses connected with the execution of portfolio security  transactions,
insurance  premiums,  fees and expenses of the custodian for all services to the
Fund,  including  safekeeping  of funds  and  securities,  keeping  of books and
accounts and calculation of the net asset value of shares of the Fund,  expenses
of shareholders'  meetings, and expenses relating to the issuance,  registration
and qualification of shares of the Fund.

         ARTICLE 3: COMPENSATION OF THE ADVISER. For the services to be rendered
and for the  facilities  to be  furnished as provided in Articles 1 and 2 above,
the Series shall pay to the Adviser a fee computed and paid monthly in an amount
equal to the sum of .30% of the  average  daily net  assets of the  Series  plus
4.09% of the adjusted  gross income  (i.e.,  income other than proceeds from the
sale of  securities)  of the  Series,  in each case on an  annual  basis for the
Series'  then-current fiscal year, provided that such computation shall commence
on the effective  date of this Agreement and shall be based on the average daily
net assets and  adjusted  gross  income of the Fund on the after such date;  and
provided further that:

         The  Adviser  will pay to the Series a sum equal to the amount by which
the  aggregate  expenses  of the Fund  incurred  during such  fiscal  year,  but
excluding interest, taxes and brokerage commissions, exceed the lesser of either
25% of gross  income of the  Series for the  preceding  year or the sum of (a) 1
1/2% of the average daily net assets of the Series for the preceding  year up to
and including  $40,000,000  and (b) 1% of any excess of average daily net assets
of the Series for the preceding year over $40,000,000.

         The  obligation  of the Adviser to  reimburse  the Series for  expenses
incurred  for any year may be  terminated  or revised at any time by the Adviser
without  the  consent of the Fund by notice in writing  from the  Adviser to the
Fund,  provided,   however,  that  termination  or  revision  of  the  Adviser's
obligation to reimburse for expenses is not to be effective  with respect to the
fiscal year within which such notice is given.

         If the  Adviser  shall  serve  for less  than the  whole of any  period
specified in this Article 3, the compensation to the Adviser shall be prorated.

         ARTICLE 4:  COVENANTS OF THE ADVISER.  The Adviser  agrees that it will
not deal with itself,  or with the Trustees of the Fund or the Fund's  principal
underwriter  as principals  in making  purchases or sales of securities or other
property  for the account of the Fund,  except as  permitted  by the  Investment
Company Act of 1940 and the Rules,  Regulations or orders  thereunder,  will not
take a long or short  position in the shares of the Series except as provided by
the  Declaration,  and will comply with all other  provisions of the Declaration
and the By-Laws relative to the Adviser and its directors and officers.

         ARTICLE 5:  LIMITATION  OF LIABILITY OF THE ADVISER.  The Adviser shall
not be  liable  for any  error of  judgment  or  mistake  of law or for any loss
arising out of any  investment  or for any act or omission in the  execution and
management  of the Series,  except for willful  misfeasance,  bad faith or gross
negligence in the performance of its duties, or by reason of reckless  disregard
of its duties and  obligations  hereunder.  As used in this  Article 5, the term
"Adviser" shall include directors, officers and employees of the Adviser as well
as the corporation itself.

         ARTICLE 6:  ACTIVITIES  OF THE ADVISER.  The services of the Adviser to
the Series  are not deemed to be  exclusive,  the  Adviser  being free to render
services to others.  The Adviser may permit  other fund clients to use the words
"Massachusetts  Financial"  in their names.  The Fund agrees that if the Adviser
shall for any reason no longer  serve as the Adviser to the Fund,  the Fund will
change  its name so as to delete  the  words  "Massachusetts  Financial".  It is
understood that the Trustees,  officers, and shareholders of the Fund are or may
be or become interested in the Adviser, as directors,  officers,  employees,  or
otherwise and that  directors,  officers and employees of the Adviser are or may
become  similarly  interested in the Fund, and that the Adviser may be or become
interested in the Fund as a shareholder or otherwise.

         ARTICLE 7: DURATION, TERMINATION AND AMENDMENTS OF THIS AGREEMENT. This
Agreement  shall become  effective on the date of its execution and shall govern
the relations between the parties hereto  thereafter,  and shall remain in force
until  August 1, 1988 on which date it will  terminate  unless  its  continuance
after August 1, 1988 is specifically  approved at least annually (i) by the vote
of a majority of the Trustees of the Fund who are not interested  persons of the
Fund or of the  Adviser  at a meeting  specifically  called  for the  purpose of
voting on such  approval,  and (ii) by the Board of Trustees of the Fund,  or by
vote of a majority of the  outstanding  voting  securities  of the  Series.  The
aforesaid  requirement  that  continuance  of this  Agreement  be  "specifically
approved at least annually"  shall be construed in a manner  consistent with the
Investment Company Act of 1940 and the Rules and Regulations thereunder.

         This Agreement may be terminated at any time without the payment of any
penalty by the  Trustees  or by vote of a  majority  of the  outstanding  voting
securities  of the Series,  or by the Adviser,  on not more than sixty days' nor
less than thirty days' written notice to the other party.  This Agreement  shall
automatically terminate in the event of its assignment.

         This  Agreement  may be amended  only if such  agreement is approved by
vote of a majority of the outstanding voting securities of the Series.

         The terms "vote of a majority of the  outstanding  voting  securities",
"assignment",  "affiliated person",  and "interested person",  when used in this
Agreement,  shall  have the  respective  meanings  specified  in the  Investment
Company Act of 1940 and the Rules and Regulations thereunder,  subject, however,
to such  exemptions as may be granted by the Securities and Exchange  Commission
under said Act.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed and  delivered  in their names and on their  behalf by the  undersigned
officers  thereunto duly  authorized,  and their  respective  seals to be hereto
affixed, all as of the day and year first above written. The undersigned Trustee
of the Fund has executed this Agreement not  individually,  but as Trustee under
the  Declaration  and the obligations of this Agreement are not binding upon any
of the Trustees or  shareholders  of the Fund,  individually,  but bind only the
trust estate.

                             DISTRIBUTION AGREEMENT

         DISTRIBUTION  AGREEMENT,  made this first day of January,  1995, by and
between MFS SERIES TRUST III, a Massachusetts  business trust (the "Trust"),  on
behalf of each series from time to time of the Trust  (referred to  individually
as a "Fund" and collectively as the "Funds") and MFS FUND DISTRIBUTORS,  INC., a
Delaware corporation (the "Distributor");

         NOW,   THEREFORE,   in   consideration   of  the  mutual  promises  and
undertakings herein contained, the parties hereto agree as follows:

         1. The  Trust  grants to the  Distributor  the  right,  as agent of the
Trust,  to sell Shares of Beneficial  Interest,  without par value, of the Funds
(the  "Shares")  upon the terms  herein  below set forth during the term of this
Agreement.  While this Agreement is in force, the Distributor  agrees to use its
best efforts to find purchasers for Shares.

         The  Distributor  shall have the right, as agent of the Trust, to order
from the Trust the Shares  needed,  but not more than the Shares needed  (except
for clerical errors and errors of transmission) to fill unconditional orders for
Shares  placed  with the  Distributor  by  dealers,  banks  or  other  financial
institutions  or investors as set forth in the current  Prospectus and Statement
of  Additional  Information  (collectively,  the  "Prospectus")  relating to the
Shares.  The price which shall be paid to the Trust for the Shares so  purchased
shall be the net asset value used in  determining  the public  offering price on
which such orders were based. The Distributor  shall notify the Custodian of the
Trust,  at the end of each  business  day, or as soon  thereafter  as the orders
placed  with it have been  compiled,  of the  number of  Shares  and the  prices
thereof  which have been ordered  through the  Distributor  since the end of the
previous day.

         The right  granted to the  Distributor  to place orders for Shares with
the Trust shall be exclusive,  except that said exclusive  right shall not apply
to Shares issued in the event that an investment company (whether a regulated or
private  investment  company  or  a  personal  holding  company)  is  merged  or
consolidated  with the Trust  (or a Fund) or in the  event  that the Trust (or a
Fund) acquires by purchase or otherwise,  all (or substantially  all) the assets
or the  outstanding  shares  of any such  company;  nor shall it apply to Shares
issued  by the  Trust  (or a Fund) as a stock  dividend  or a stock  split.  The
exclusive  right to place orders for Shares  granted to the  Distributor  may be
waived  by  the   Distributor  by  notice  to  the  Trust  in  writing,   either
unconditionally  or subject to such  conditions  and  limitations  as may be set
forth in the  notice  to the  Trust.  The  Trust  hereby  acknowledges  that the
Distributor  may  render  distribution  and  other  services  to other  parties,
including other investment  companies.  In connection with its duties hereunder,
the  Distributor  shall also arrange for  computation of performance  statistics
with  respect  to the  Trust  and  arrange  for  publication  of  current  price
information in newspapers and other publications.

         2. The Shares may be sold through the Distributor to dealers, banks and
other financial institutions having sales agreements with the Distributor,  upon
the following terms and conditions:

         The  public  offering  price,  i.e.,  the  price per Share at which the
Distributor or dealers, banks or other financial institutions  purchasing Shares
through  the  Distributor  may sell  Shares to the  public,  shall be the public
offering  price as set forth in the current  Prospectus  relating to the Shares,
including a sales charge (where  applicable) not to exceed the amount  permitted
by Article III,  Section 26 of the National  Association of Securities  Dealers,
Inc.'s Rule of Fair  Practice,  as amended  from time to time.  The  Distributor
shall retain the sales charge (where  applicable) less any applicable  dealer or
comparable discount. If the resulting public offering price does not come out to
an even cent, the public offering price shall be adjusted to the nearer cent. In
addition,  the Trust agrees that the Distributor  may impose certain  contingent
deferred sales charges (where  applicable) in connection  with the redemption of
Shares,  not to exceed 6% of the net asset value of Shares,  and the Distributor
shall retain (or receive from the Trust, as the case may be) all such contingent
deferred sales charges.

         The  Distributor may place orders for Shares at the net asset value for
such Shares (as  established  pursuant  to  paragraph l above) on behalf of such
purchasers and under such  circumstances as the Prospectus  describes,  provided
that such sales comply with Rule 22d-1 under the Investment  Company Act of 1940
or any exemptive  order granted by the Securities and Exchange  Commission.  The
Distributor  may also place  orders  for Shares at net asset  value on behalf of
persons reinvesting the proceeds of the redemption or resale of Shares or shares
of other  investment  companies for which the Distributor acts as Distributor or
as otherwise provided in the current Prospectus.

         The net asset value of Shares shall be determined by the Trust or by an
agent of the  Trust,  as of the close of  regular  trading of the New York Stock
Exchange on each business day on which said Exchange is open, in accordance with
the method set forth in the governing  instruments (as  hereinafter  defined) of
the Trust.  The Trust may also  cause the net asset  value to be  determined  in
substantially  the same manner or  estimated in such manner and as of such other
hour or hours as may from time to time be agreed  upon in  writing  by the Trust
and  Distributor.  The Trust  shall have the right to suspend the sale of Shares
if, because of some extraordinary  condition,  the New York Stock Exchange shall
be closed, or if conditions obtaining during the hours when the Exchange is open
render such action  advisable,  or for any other reasons deemed  adequate by the
Trust.

         3. The Trust agrees that it will, from time to time, take all necessary
action to register the offering and sale of Shares under the  Securities  Act of
l933, as amended (the "Act"), and applicable state securities laws.

         The  Distributor  shall be an  independent  contractor  and neither the
Distributor nor any of its directors, officers or employees as such, is or shall
be an  employee of the Trust.  It is  understood  that  Trustees,  officers  and
shareholders of the Trust are or may become  interested in the  Distributor,  as
Directors, officers and employees, or otherwise and that Directors, officers and
employees of the Distributor are or may become similarly interested in the Trust
and  that  the  Distributor  may  be or  become  interested  in the  Trust  as a
shareholder or otherwise. The Distributor is responsible for its own conduct and
the  employment,  control and conduct of its agents and employees and for injury
to such agents or employees or to others  through its agents or  employees.  The
Distributor  assumes  full  responsibility  for its agents and  employees  under
applicable statutes and agrees to pay all employer taxes thereunder.

         4. The  Distributor  covenants and agrees that, in selling  Shares,  it
will use its best efforts in all respects duly to conform with the  requirements
of all state and federal  laws and the Rules of Fair  Practice  of the  National
Association  of Securities  Dealers,  Inc. (the "NASD")  relating to the sale of
Shares,  and will indemnify and hold harmless the Trust and each of its Trustees
and officers and each person,  if any, who controls the Trust within the meaning
of Section 15 of the Act, against any loss, liability, damages, claim or expense
(including the reasonable cost of  investigating  or defending any alleged loss,
liability,  damages,  claim or expense and  reasonable  counsel fees incurred in
connection  therewith),  arising by reason of any person's acquiring any Shares,
which may be based upon the Act or any other  statute or common  law, on account
of any wrongful act of the  Distributor  or any of its employees  (including any
failure to conform with any requirement of any state or federal law or the Rules
of Fair  Practice  of the NASD  relating to the sale of Shares) or on the ground
that the  registration  statement or Prospectus as from time to time amended and
supplemented,  includes an untrue statement of a material fact or omits to state
a material fact required to be stated  therein or necessary in order to make the
statements  therein not misleading,  unless any such act,  statement or omission
was made in reliance  upon  information  furnished to the  Distributor  by or on
behalf of the Trust, provided,  however, that in no case (i) is the indemnity of
the  Distributor in favor of any person  indemnified to be deemed to protect the
Trust or any such person  against any  liability  to which the Trust or any such
person would otherwise be subject by reason of willful misfeasance, bad faith or
gross  negligence in the performance of its or his duties or by reason of its or
his reckless  disregard of its obligations  and duties under this Agreement,  or
(ii) is the Distributor to be liable under its indemnity  agreement contained in
this  paragraph  with  respect to any claim made against the Trust or any person
indemnified  unless  the Trust or such  person,  as the case may be,  shall have
notified the  Distributor in writing within a reasonable  time after the summons
or other first legal process giving information of the nature of the claim shall
have been  served upon the Trust or upon such person (or after the Trust or such
person shall have received notice of such service on any designated  agent), but
failure to notify the  Distributor  of any such claim  shall not relieve it from
any  liability  which it may have to the Trust or any person  against  whom such
action is brought otherwise than on account of its indemnity agreement contained
in this paragraph. The Distributor shall be entitled to participate,  at its own
expense, in the defense,  or, if it so elects, to assume the defense of any suit
brought to enforce any such liability,  but, if the Distributor elects to assume
the  defense,  such  defense  shall be  conducted  by  counsel  chosen by it and
satisfactory to the Trust, or to its officers or Trustees, or to any controlling
person or persons,  defendant or  defendants  in the suit. In the event that the
Distributor  elects to assume  the  defense  of any such  suit and  retain  such
counsel,  the  Trust or such  officers  or  Trustees  or  controlling  person or
persons,  defendant or defendants in the suit,  shall bear the fees and expenses
of any additional  counsel  retained by them, but, in case the Distributor  does
not elect to assume the defense of any such suit,  it shall  reimburse the Trust
and such officers and Trustees or  controlling  person or persons,  defendant or
defendants  in such suit,  for the  reasonable  fees and expenses of any counsel
retained by them.  The  Distributor  agrees  promptly to notify the Trust of the
commencement of any litigation or proceedings  against it in connection with the
issue and sale of any Shares.  Neither the  Distributor  nor any other person is
authorized to give any  information or to make any  representation  on behalf of
the  Trust,  other  than  those  contained  in  the  registration  statement  or
Prospectus  filed with the Securities and Exchange  Commission under the Act (as
said  registration  statement or Prospectus may be amended or supplemented  from
time to time),  covering  the Shares or other than those  contained  in periodic
reports to shareholders of the Trust.

         5. The Trust will pay, or cause to be paid -

         (i)  all  costs  and  expenses  of  the  Trust,   including   fees  and
disbursements  of its counsel,  in connection with the preparation and filing of
any required registration  statement or Prospectus under the Act covering Shares
and all  amendments  and  supplements  thereto  and any  notices  regarding  the
registration of shares, and preparing and mailing to shareholders  Prospectuses,
statements  and  confirmations  and periodic  reports  (including the expense of
setting  up in type any such  registration  statement,  Prospectus  or  periodic
report);

         (ii) the expenses (including auditing expenses) of qualification of the
Shares for sale,  and, if necessary or advisable  in  connection  therewith,  of
qualifying the Trust as a dealer or broker,  in such states as shall be selected
by the  Distributor  and the fees  payable to each such  state  with  respect to
shares sold and for continuing the  qualification  therein until the Distributor
notifies the Trust that it does not wish such qualification continued;

         (iii) the cost of preparing  temporary or  permanent  certificates  for
Shares;

         (iv) all fees and disbursements of the transfer agent of the Trust;

         (v) the cost and  expenses  of  delivering  to the  Distributor  at its
office in Boston,  Massachusetts,  all  Shares  sold  through it as  Distributor
hereunder; and

         (vi) all the federal and state issue and/or transfer taxes payable upon
the issue by or (in the case of treasury  Shares) transfer from the Trust of any
and all Shares purchased through the Distributor hereunder.

         The Distributor  agrees that, after the Prospectus and periodic reports
have  been set up in type,  it will  bear the  expense  (other  than the cost of
mailing to  shareholders  of the Trust of printing and  distributing  any copies
thereof  which  are to be used in  connection  with the  offering  of  Shares to
dealers,  banks or other financial  institutions  or investors.  The Distributor
further  agrees  that it will  bear the  expenses  of  preparing,  printing  and
distributing any other literature used by the Distributor or furnished by it for
use by dealers,  banks or other  financial  institutions  in connection with the
offering  of the Shares for sale to the public and  expenses of  advertising  in
connection  with such offering.  The  Distributor  will also bear the expense of
sending  confirmations  and  statements  to dealers,  banks and other  financial
institutions  having  sales  agreements  with the  Distributor.  Nothing in this
paragraph  5 shall be deemed to  prohibit  or  conflict  with any payment by the
Trust or any Fund to the Distributor  pursuant to any Distribution  Plan adopted
as in effect pursuant to Rule 12b-1 under the Investment Company Act of 1940.

         6. The Trust hereby authorizes the Distributor to repurchase,  upon the
terms and conditions set forth in written instructions given by the Trust to the
Distributor  from time to time, as agent of the Trust and for its account,  such
Shares as may be offered for sale to the Trust from time to time;  provided  the
Distributor  shall  have the  right,  as  stated  above in  paragraph  2 of this
Agreement,  to  retain  (or to  receive  from the  Trust,  as the case may be) a
deferred  sales  charge not to exceed 6% of the net asset value of the Shares so
repurchased.

         (a) The Distributor shall notify in writing the Custodian of the Trust,
at the end of each business day, or as soon thereafter as the  repurchases  have
been compiled,  of the number of Shares repurchased for the account of the Trust
since  the last  previous  report,  together  with  the  prices  at  which  such
repurchases  were made,  and upon the  request of any  Officer or Trustee of the
Trust shall furnish similar  information with respect to all repurchases made up
to the time of the request on any day.

         (b) The Trust  reserves  the right to suspend  or revoke the  foregoing
authorization  at any time.  Unless  otherwise  stated,  any such  suspension or
revocation  shall be effective  forthwith  upon receipt of notice  thereof by an
officer of the Distributor, by telegraph or by written notice from the Trust. In
the event that the  authorization  of the  Distributor  is, by the terms of such
notice,  suspended for more than twenty-four hours or until further notice,  the
authorization given by this paragraph 6 shall not be revived except by action of
a majority of the members of the Board of Trustees of the Trust.

         (c) The Distributor  shall have the right to terminate the operation of
this paragraph 6 upon giving to the Trust thirty days' written notice thereof.

         (d) The Trust agrees to authorize  and direct the Custodian to pay, for
the  account  of the Trust,  the  purchase  price of any  Shares so  repurchased
against delivery of the certificates, if any, in proper form for transfer to the
Trust or for cancellation by the Trust.

         (e) The  Distributor  shall  receive  no  commission  in respect of any
repurchase of Shares under the foregoing authorization and appointment as agent,
except in connection  with  contingent  deferred sales charge as provided in the
current Prospectus relating to the Shares.

         (f) The Trust agrees to reimburse  the  Distributor,  from time to time
upon  demand,  for any  reasonable  expenses  incurred  in  connection  with the
repurchase of Shares pursuant to this paragraph 6.

         7. If, at any time during the  existence of this  Agreement,  the Trust
shall deem it necessary or advisable in the best interests of the Trust that any
amendment of this Agreement be made in order to comply with the  recommendations
or requirements of the Securities and Exchange  Commission or other governmental
authority or to obtain any advantage under  Massachusetts,  any state or federal
tax laws,  it shall notify the  Distributor  of the form of  amendment  which it
deems  necessary  or advisable  and the reasons  therefore.  If the  Distributor
declines to assent to such  amendment,  the Trust may terminate  this  Agreement
forthwith by written notice to the  Distributor  without payment of any penalty.
If, at any time during the  existence  of this  Agreement,  upon  request by the
Distributor,  the Trust fails (after a  reasonable  time) to make any changes in
its  governing  instruments  or in its  methods  of  doing  business  which  are
necessary in order to comply with any  requirements  of federal or state laws or
regulations, laws or regulations of the Securities and Exchange Commission or of
a  national  securities  association  of which  the  Distributor  is or may be a
member,  relating to the sale of Shares,  the  Distributor  may  terminate  this
Agreement  forthwith  by  written  notice to the Trust  without  payment  of any
penalty.

         8.  The  Distributor  agrees  that it will  not  take any long or short
positions  in the  Shares  except as  permitted  by  paragraphs  l and 6 hereof.
Whenever used in this Agreement, the term "governing instruments" shall mean the
Declaration of Trust and the By-Laws of the Trust, as from time to time amended.

         9. This Agreement  shall become  effective on January 1, 1995 and shall
continue in force until  August 1, 1996 on which date it will  terminate  unless
its continuance after August 1, 1996, is specifically approved at least annually
(i) by the vote of a majority  of the Board of Trustees of the Trust who are not
interested persons of the Trust or of the Distributor at a meeting  specifically
called  for the  purpose  of voting on such  approval,  and (ii) by the Board of
Trustees  of the  Trust  or by  vote of a  majority  of the  outstanding  voting
securities of that Fund.  The aforesaid  requirement  that  continuance  of this
Agreement be  "specifically  approved at least annually" shall be construed in a
manner  consistent  with the  Investment  Company  Act of l940 and the Rules and
Regulations thereunder.

         This  Agreement  may be terminated as to any Fund at any time by either
party  without  payment of any penalty on not more than sixty days' or less than
thirty days' written notice to the other party.

         10. This Agreement  shall  automatically  terminate in the event of its
assignment.

         11.  The  terms  "vote  of  a  majority  of  the   outstanding   voting
securities",  "interested  person" and  "assignment"  shall have the  respective
meanings  specified  in the  Investment  Company  Act of l940 and the  Rules and
Regulations thereunder,  subject,  however, to such exemptions as may be granted
by the Securities and Exchange Commission under said Act.

         12. This Agreement shall be governed by the laws of The Commonwealth of
Massachusetts.

         13. A copy of the Declaration of Trust of the Trust is on file with the
Secretary  of  State  of The  Commonwealth  of  Massachusetts.  The  Distributor
acknowledges  that the  obligations of or arising out of this instrument are not
binding  upon  any of the  Trust's  trustees,  officers,  employees,  agents  or
shareholders  individually,  but are binding solely upon the assets and property
of the Trust.  If this  instrument  is executed by the Trust on behalf of one or
more series of the Trust, the Distributor  further  acknowledges that the assets
and  liabilities  of each series of the Trust are separate and distinct and that
the obligations of or arising out of this instrument are binding solely upon the
assets or property  of the series on whose  behalf the Trust has  executed  this
instrument. If the Trust has executed this instrument on behalf of more than one
series of the Trust,  the  Distributor  also agrees that the obligations of each
series  hereunder  shall  be  several  and not  joint,  in  accordance  with its
proportionate  interest  hereunder,  and the  Distributor  agrees not to proceed
against any series for the obligations of another series.

         IN WITNESS WHEREOF,  the parties hereto have executed this Agreement as
of the day and year first above.

                              MFS HIGH INCOME FUND

                     AMENDED AND RESTATED DISTRIBUTION PLAN


AMENDED AND RESTATED  DISTRIBUTION PLAN with respect to the shares of beneficial
interest to be designated "CLASS A" of the MFS HIGH INCOME FUND (the "Fund"),  a
series of MFS Series Trust III (the  "Trust"),  a business  trust  organized and
existing under the laws of The Commonwealth of Massachusetts, dated the 19th day
of December, 1990, amended and restated the 24th day of August, 1993 and amended
this 21st day of December, 1994.

                                  WITNESSETH:


WHEREAS,  the Trust is engaged in business as an open-end management  investment
company and is registered under the Investment  Company Act of 1940 (the "Act");
and

WHEREAS, a plan of distribution pursuant to Rule 12b-1 of the Act was previously
adopted and  approved by the  Trustees of the Trust,  including  the  Qualifying
Trustees (as defined below), and by the shareholders of the Fund; and

WHEREAS,  the Trust intends to continue to  distribute  the Shares of Beneficial
Interest  (without  par  value)  of the  Fund  designated  Class A  Shares  (the
"Shares") in part in  accordance  with Rule 12b-1 under the Act ("Rule  12b-1"),
and desires to adopt this amended and restated Distribution Plan (the "Plan") as
a plan of distribution pursuant to such Rule; and

WHEREAS, the Trust has entered into a distribution  agreement (the "Distribution
Agreement") in a form approved by the Board of Trustees of the Trust (the "Board
of Trustees") in the manner specified in Rule 12b-1, with MFS Fund Distributors,
Inc., a Delaware  corporation,  as distributor (the "Distributor"),  whereby the
Distributor  provides  facilities and personnel and renders services to the Fund
in connection with the offering and distribution of the Shares; and

WHEREAS,  the Trust  recognizes and agrees that the Distributor  will enter into
agreements  ("Dealer  Agreements")  with  various  securities  dealers and other
financial  intermediaries  ("Dealers") pursuant to which the Dealers will act as
dealers of the Shares in connection with the offering of Shares; and

WHEREAS, the Distribution  Agreement provides that a sales charge may be paid by
investors who purchase  Shares and that the Distributor and Dealers will receive
such sales charge as partial  compensation for their services in connection with
sale of Shares; and

WHEREAS, the Board of Trustees, in considering whether the Fund should adopt and
implement this Plan, has evaluated such information as it deemed necessary to an
informed determination as to whether this Plan should be adopted and implemented
and has  considered  such pertinent  factors as it deemed  necessary to form the
basis  for a  decision  to use  assets  of the Fund for such  purposes,  and has
determined  that  there  is  a  reasonable  likelihood  that  the  adoption  and
implementation of this Plan will benefit the Fund and its Class A shareholders;

NOW, THEREFORE,  the Board of Trustees hereby adopts this Plan for the Fund as a
plan of distribution  relating to the Shares in accordance with Rule 12b-1 under
the Act, on the following terms and conditions:

         1. As specified in the Distribution  Agreement,  the Distributor  shall
provide  facilities,  personnel  and a program  with respect to the offering and
sale of Shares. Among other things, the Distributor shall be responsible for all
expenses of printing  (excluding  typesetting) and distributing  prospectuses to
prospective  shareholders  and  providing  such other  related  services  as are
reasonably necessary in connection therewith.

         2. The Distributor shall bear all distribution-related  expenses to the
extent  specified  in the  Distribution  Agreement  in  providing  the  Services
described  in Section 1,  including  without  limitation,  the  compensation  of
personnel  necessary  to provide such  services and all costs of travel,  office
expenses  (including  rent and  overhead),  equipment,  printing,  delivery  and
mailing costs.

         3. As partial  consideration  for the services  performed  and expenses
incurred in the performance of its obligations under the Distribution Agreement,
the Fund shall pay the Distributor a distribution  fee periodically at a rate of
0.10% per annum of the average daily net assets of the Fund  attributable to the
Shares. Such payments shall commence following  shareholder approval of the Plan
but only upon notification by the Distributor to the Fund of the commencement of
the Plan (the "Commencement Date").

         4. As partial  consideration  for the personal  services and/or account
maintenance  services  performed  by  each  Dealer  in  the  performance  of its
obligations  under  its  Dealer  Agreement,  the  Fund  shall  on or  after  the
Commencement  Date pay each Dealer a service fee  periodically  at a rate not to
exceed  0.25% per annum of the  portion of the  average  daily net assets of the
Fund that is  represented  by Shares that are owned by  investors  for whom such
Dealer is the holder or dealer of record.  The Distributor may from time to time
reduce the amount of the  service  fee paid to a Dealer for Shares sold prior to
certain date.

         5. In addition to fees payable pursuant to Sections 3 and 4 hereof, the
expenses  permitted to be paid by the Fund pursuant to this Plan on or after the
Commencement Date shall include other distribution related expenses. These other
distribution  related  expenses  may  include,  but are not limited to, a dealer
commission and a payment to wholesalers employed by the Distributor on net asset
value purchases at or above a certain dollar level.

         The  aggregate  amount of fees and expenses paid pursuant to Sections 3
and 4 hereof and this  Section 5 shall not exceed 0.35% per annum of the average
daily net assets of the Fund  attributable to the Shares.  No fees shall be paid
pursuant to Section 4 hereof or this Section 5 to any  insurance  company  which
has  entered  into an  agreement  with the  Trust on  behalf of the Fund and the
Distributor that permits such insurance company to purchase Shares from the Fund
at their  net  asset  value in  connection  with  annuity  agreements  issued in
connection with the insurance  company's separate accounts.  That portion of the
Fund's average daily net assets on which fees payable under Section 4 hereof and
this  Section  5 are  calculated  may  be  subject  to  certain  minimum  amount
requirements  as may be  determined,  and  additional  or  different  dealer  or
wholesaler qualification standards that may be established, from time to time by
the Distributor.  The Distributor  shall be entitled to be paid any fees payable
under  Section 4 hereof or this  Section 5 with respect to accounts for which no
Dealer of record exists or qualification  standards have not been met as partial
consideration for personal services and/or account maintenance services provided
by the  Distributor  to the Shares.  The fees and expenses  payable  pursuant to
Section  4 and this  Section  5 may from time to time be paid by the Fund to the
Distributor  and the  Distributor  will then pay these expenses on behalf of the
Fund.

         6.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         7. This Plan shall become  effective  upon (a) approval by a vote of at
least a "majority of the outstanding  voting  securities" of the Shares, and (b)
approval  by a vote of the  Board  of  Trustees  and vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest  in the  operation  of the  Plan  or in any of the
agreements related to the Plan (the "Qualified Trustees"), such votes to be cast
in person at a meeting called for the purpose of voting on this Plan.

         8. This Plan shall continue in effect indefinitely;  provided, however,
that such  continuance  is subject to annual  approval by a vote of the Board of
Trustees  and a majority  of the  Qualified  Trustees,  such votes to be cast in
person at a meeting  called  for the  purpose of voting on  continuance  of this
Plan. If such annual approval is not obtained,  this Plan shall expire 12 months
after the effective date of the last approval.

         9.  This  Plan may be  amended  at any time by the  Board of  Trustees;
provided  that (a) any amendment to increase  materially  the amount to be spent
for the services  described  herein shall be effective  only upon  approval by a
vote of a "majority of the outstanding  voting securities" of the Shares and (b)
any material  amendment of this Plan shall be effective  only upon approval by a
vote of the Board of Trustees  and a majority of the  Qualified  Trustees,  such
votes to be cast in person at a meeting called for the purpose of voting on such
amendment.  This Plan may be terminated at any time by vote of a majority of the
Qualified  Trustees  or by a  vote  of a  "majority  of the  outstanding  voting
securities" of the Shares.

         10. The Distributor shall provide the Board of Trustees,  and the Board
of Trustees shall review,  at least  quarterly,  a written report of the amounts
expended under the Plan and the purposes for which such expenditures were made.

         11.  While this Plan is in effect,  the  selection  and  nomination  of
Qualified  Trustees shall be committed to the discretion of the Trustees who are
not "interested persons" of the Trust.

         12. For the purposes of this Plan,  the terms  "interested  person" and
"majority of the outstanding  voting securities" are used as defined in the Act.
In  addition,  for  purposes  of  determining  the fees  payable to Dealers  and
wholesalers, the value of the Share's net assets shall be computed in the manner
specified in the Fund's then current prospectus for computation of the net asset
value of the Shares.

         13. The Trust shall  preserve  copies of this Plan,  and each agreement
related  hereto and each report  referred to in Section 10 hereof  (collectively
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  Record  shall be kept in an easily
accessible place for the first two years of said record keeping.

         14. This Plan shall be  construed  in  accordance  with the laws of The
Commonwealth of Massachusetts and the applicable provisions of the Act.

         15. If any  provision  of this Plan shall be held or made  invalid by a
court decision,  statute, rule or otherwise, the remainder of the Plan shall not
be affected thereby.

                              PLAN OF DISTRIBUTION


         PLAN OF DISTRIBUTION with respect to the shares of beneficial  interest
to be designated "CLASS B" of MFS HIGH INCOME FUND (the "Fund"), a series of MFS
Series Trust III (the "Trust") a Massachusetts  business trust,  dated September
1, 1993 and amended this 21st day of December, 1994.

                                  WITNESSETH:


         WHEREAS,  the Trust is engaged in business  as an  open-end  management
investment  company and is registered under the Investment  Company Act of 1940,
as amended (collectively with the rules and regulations  promulgated thereunder,
the "1940 Act"); and

         WHEREAS,  the Trust  intends to  distribute  the  shares of  beneficial
interest  (without  par  value)  of the  Fund  designated  Class B  Shares  (the
"Shares") in accordance with Rule 12b-1 under the 1940 Act ("Rule  12b-1"),  and
desires to adopt this  Distribution  Plan (the "Plan") as a plan of distribution
pursuant to such Rule; and

         WHEREAS, the Trust desires for MFS Fund Distributors,  Inc., a Delaware
corporation,  to  provide  certain  distribution  services  for  the  Fund  (the
"Distributor"); and

         WHEREAS,  the Trust has  entered  into a  distribution  agreement  (the
"Distribution  Agreement")  (in a form  approved by the Board of Trustees of the
Trust in a manner  specified in such Rule 12b-1) with the  Distributor,  whereby
the Distributor will provide facilities and personnel and render services to the
Fund in connection with the offering and distribution of the Shares; and

         WHEREAS,  the Trust  recognizes and agrees that (a) the Distributor may
retain the services of firms or individuals to act as dealers (the "Dealers") of
the Shares in connection  with the offering of Shares,  and (b) the  Distributor
may make  payments  for such  services to the Dealers out of the fee paid to the
Distributor hereunder,  any deferred sales charges imposed by the Distributor in
connection  with the  repurchase  of Shares,  its  profits  or any other  source
available to it; and

         WHEREAS,  the Trust  recognizes  and agrees  that the  Distributor  may
impose  certain  deferred  sales  charges in connection  with the  repurchase of
Shares by the Fund, and the Distributor may retain (or receive from the Fund, as
the case may be) all such deferred sales charges; and

         WHEREAS, the Board of Trustees of the Trust, in considering whether the
Fund should adopt and implement this Plan, has evaluated such  information as it
deemed necessary to an informed  determination as to whether this Plan should be
adopted and implemented  and has considered such pertinent  factors as it deemed
necessary  to form the basis for a  decision  to use assets of the Fund for such
purposes,  and has  determined  that there is a reasonable  likelihood  that the
adoption and  implementation  of this Plan will benefit the Fund and its Class B
shareholders;

         NOW,  THEREFORE,  the Board of Trustees of the Trust hereby adopts this
Plan  for  the  Fund  as a plan  for  distribution  relating  to the  Shares  in
accordance with Rule 12b-1, on the following terms and conditions:

         1. As specified in the Distribution  Agreement,  the Distributor  shall
provide  facilities,  personnel  and a program  with respect to the offering and
sale of Shares.  Among other things,  the  Distributor  shall be responsible for
commissions payable to Dealers, all expenses of printing (excluding typesetting)
and  distributing  prospectuses to prospective  shareholders  and providing such
other related services as are reasonably necessary in connection therewith.

         2. The Distributor shall bear all distribution-related  expenses to the
extent  specified  in the  Distribution  Agreement  in  providing  the  services
described in paragraph 1, including  without  limitation,  the  compensation  of
personnel  necessary  to provide such  services and all costs of travel,  office
expenses  (including  rent and  overhead),  equipment,  printing,  delivery  and
mailing costs.

         3. It is understood that the  Distributor  may impose certain  deferred
sales  charges in connection  with the  repurchase of Shares by the Fund and the
Distributor  may retain (or receive from the Fund,  as the case may be) all such
deferred sales charges.  As additional  consideration for all services performed
and  expenses   incurred  in  the  performance  of  its  obligations  under  the
Distribution  Agreement,  the Fund shall pay the Distributor a distribution  fee
periodically at a rate of 0.75% per annum of the Fund's average daily net assets
attributable to the Shares.

         4. As partial  consideration  for the personal  services and/or account
maintenance  services  performed  by  each  Dealer  in  the  performance  of its
obligations under its dealer agreement with the Distributor,  the Fund shall pay
each Dealer a service fee  periodically  at a rate not to exceed 0.25% per annum
of the portion of the average  daily net assets of the Fund that is  represented
by Shares  that are owned by  investors  for whom such  Dealer is the  holder or
dealer of record.  That portion of the Fund's  average daily net assets on which
the fees payable under this  paragraph 4 hereof are calculated may be subject to
certain  minimum amount  requirements  as may be  determined,  and additional or
different  dealer  qualification  standards that may be established from time to
time, by the Distributor.  The Distributor shall be entitled to be paid any fees
payable under this paragraph 4 hereof with respect to Shares for which no Dealer
of  record  exists  or  qualification  standards  have not  been met as  partial
consideration for personal services and/or account maintenance services provided
by the  Distributor  to the Shares.  The  service  fee payable  pursuant to this
paragraph 4 may from time to time be paid by the Fund to the Distributor and the
Distributor will then pay these fees on behalf of the Fund.

         5. The Fund understands that agreements between the Distributor and the
Dealers may provide for payment of commissions to Dealers in connection with the
sales of Shares and may provide for a portion (which may be all or substantially
all) of the fees payable by the Fund to the Distributor  under the  Distribution
Agreement to be paid by the Distributor to the Dealers in  consideration  of the
Dealer's services as a dealer of the Shares. Except as described in paragraph 4,
nothing  in this  Plan  shall be  construed  as  requiring  the Fund to make any
payment to any  Dealer or to have any  obligations  to any Dealer in  connection
with  services  as a dealer  of the  Shares.  The  Distributor  shall  agree and
undertake that any agreement entered into between the Distributor and any Dealer
shall  provide  that,  except as provided in paragraph 4, such Dealer shall look
solely to the Distributor for compensation for its services  thereunder and that
in no event shall such Dealer seek any payment from the Fund.

         6. The Fund shall pay all fees and expenses of any independent auditor,
legal counsel,  investment adviser,  administrator,  transfer agent,  custodian,
shareholder servicing agent, registrar or dividend disbursing agent of the Fund;
expenses  of  distributing  and  redeeming  Shares  and  servicing   shareholder
accounts; expenses of preparing, printing and mailing prospectuses,  shareholder
reports,  notices,  proxy  statements and reports to  governmental  officers and
commissions and to shareholders of the Fund,  except that the Distributor  shall
be responsible for the distribution-related expenses as provided in paragraphs 1
and 2 hereof.

         7.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         8. This Plan shall become  effective  upon (a) approval by a vote of at
least a "majority of the outstanding  voting  securities" of the Shares, and (b)
approval  by a vote of the Board of  Trustees  and a vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest in the  operation of the Plan or in any  agreement
related to the Plan (the "Qualified Trustees"),  such votes to be cast in person
at a meeting called for the purpose of voting on this Plan.

         9. This Plan shall continue in effect indefinitely;  provided that such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained,  this Plan shall expire 12 months after
the effective date of the last approval.

         10.  This Plan may be  amended  at any time by the  Board of  Trustees;
provided that this Plan may not be amended to increase  materially the amount of
permitted  expenses  hereunder without the approval of holders of a "majority of
the  outstanding  voting  securities"  of the Shares  and may not be  materially
amended in any case  without a vote of a majority of both the  Trustees  and the
Qualified  Trustees.  This  Plan  may be  terminated  at any time by a vote of a
majority of the Qualified Trustees or by a vote of the holders of a "majority of
the outstanding voting securities" of the Shares.

         11. The Fund and the  Distributor  shall provide the Board of Trustees,
and the Board of Trustees shall review, at least quarterly,  a written report of
the  amounts   expended  under  this  Plan  and  the  purposes  for  which  such
expenditures were made.

         12.  While this Plan is in effect,  the  selection  and  nomination  of
Qualified  Trustees shall be committed to the discretion of the Trustees who are
not "interested persons" of the Trust.

         13. For the  purposes  of this Plan,  the terms  "interested  persons",
"majority of the outstanding  voting  securities" and "specifically  approved at
least  annually" are used as defined in the 1940 Act. In addition,  for purposes
of determining the fees payable to the Distributor  hereunder,  the value of the
Fund's net  assets  shall be  computed  in the  manner  specified  in the Fund's
then-current  prospectus and statement of additional information for computation
of the net asset value of the Shares of the Fund.

         14. The Trust shall  preserve  copies of this Plan,  and each agreement
related hereto and each report referred to in paragraph 11 hereof (collectively,
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  record  shall be kept in an easily
accessible place for the first two years of said record-keeping.

         15. This Plan shall be  construed  in  accordance  with the laws of The
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

         16. If any  provision  of this Plan shall be held or made  invalid by a
court decision,  statute, rule or otherwise, the remainder of the Plan shall not
be affected thereby.

may make  payments  for such  services to the Dealers out of the fee paid to the
Distributor hereunder,  any deferred sales charges imposed by the Distributor in
connection  with the  repurchase  of Shares,  its  profits  or any other  source
available to it; and

         WHEREAS,  the Trust recognizes and agrees that the Distributor may (but
is not required to) impose certain deferred sales charges in connection with the
repurchase  of Shares by the Fund,  and the  Distributor  may retain (or receive
from the Fund, as the case may be) all such deferred sales charges; and

         WHEREAS, the Board of Trustees of the Trust, in considering whether the
Fund should adopt and implement this Plan, has evaluated such  information as it
deemed necessary to an informed  determination as to whether this Plan should be
adopted and implemented  and has considered such pertinent  factors as it deemed
necessary  to form the basis for a  decision  to use assets of the Fund for such
purposes,  and has  determined  that there is a reasonable  likelihood  that the
adoption and  implementation  of this Plan will benefit the Fund and its Class C
shareholders;

         NOW,  THEREFORE,  the Board of Trustees of the Trust hereby adopts this
Plan  for  the  Fund  as a plan  for  distribution  relating  to the  Shares  in
accordance with Rule 12b-1, on the following terms and conditions:

         1. As specified in the Distribution  Agreement,  the Distributor  shall
provide  facilities,  personnel  and a program  with respect to the offering and
sale of Shares. Among other things, the Distributor shall be responsible for any
commissions payable to Dealers (including any ongoing maintenance  commissions),
all expenses of printing (excluding  typesetting) and distributing  prospectuses
to prospective  shareholders  and providing  such other related  services as are
reasonably necessary in connection therewith.

         2. The Distributor shall bear all distribution-related  expenses to the
extent  specified  in the  Distribution  Agreement  in  providing  the  services
described in paragraph 1, including  without  limitation,  the  compensation  of
personnel  necessary  to provide such  services and all costs of travel,  office
expenses  (including  rent and  overhead),  equipment,  printing,  delivery  and
mailing costs.

         3. It is understood  that the  Distributor may (but is not required to)
impose  certain  deferred  sales  charges in connection  with the  repurchase of
Shares by the Fund and the  Distributor may retain (or receive from the Fund, as
the case may be) all such deferred  sales charges.  As additional  consideration
for all services  performed  and  expenses  incurred in the  performance  of its
obligations under the Distribution Agreement, the Fund shall pay the Distributor
a distribution  fee  periodically at a rate not to exceed 0.75% per annum of the
Fund's average daily net assets attributable to the Shares.

         4. As partial  consideration  for the personal  services and/or account
maintenance  services  performed  by  each  Dealer  in  the  performance  of its
obligations under its dealer agreement with the Distributor,  the Fund shall pay
each Dealer a service fee  periodically  at a rate not to exceed 0.25% per annum
of the portion of the average  daily net assets of the Fund that is  represented
by Shares  that are owned by  investors  for whom such  Dealer is the  holder or
dealer of record.  That portion of the Fund's  average daily net assets on which
the fees payable under this  paragraph 4 hereof are calculated may be subject to
certain  minimum amount  requirements  as may be  determined,  and additional or
different dealer qualification  standards that may be established,  from time to
time by the Distributor.  The Distributor  shall be entitled to be paid any fees
payable under this paragraph 4 hereof with respect to Shares for which no Dealer
of  record  exists  or  qualification  standards  have not  been met as  partial
consideration for personal services and/or account maintenance services provided
by the  Distributor  to the Shares.  The  service  fee payable  pursuant to this
paragraph 4 may from time to time be paid by the Fund to the Distributor and the
Distributor  will then pay these fees to Dealers on behalf of the Fund or retain
them in accordance with this paragraph.

         5. The Fund understands that agreements between the Distributor and the
Dealers may provide for payment of commissions to Dealers in connection with the
sales of Shares and may provide for a portion (which may be all or substantially
all) of the fees payable by the Fund to the Distributor  under the  Distribution
Agreement to be paid by the Distributor to the Dealers in  consideration  of the
Dealer's services as a dealer of the Shares. Except as described in paragraph 4,
nothing  in this  Plan  shall be  construed  as  requiring  the Fund to make any
payment to any  Dealer or to have any  obligations  to any Dealer in  connection
with  services  as a dealer  of the  Shares.  The  Distributor  shall  agree and
undertake that any agreement entered into between the Distributor and any Dealer
shall  provide  that,  except as provided in paragraph 4, such Dealer shall look
solely to the Distributor for compensation for its services  thereunder and that
in no event shall such Dealer seek any payment from the Fund.


         6. The Fund shall pay all fees and expenses of any independent auditor,
legal counsel,  investment adviser,  administrator,  transfer agent,  custodian,
shareholder servicing agent, registrar or dividend disbursing agent of the Fund;
expenses  of  distributing  and  redeeming  Shares  and  servicing   shareholder
accounts; expenses of preparing, printing and mailing prospectuses,  shareholder
reports,  notices,  proxy  statements and reports to  governmental  officers and
commissions and to shareholders of the Fund,  except that the Distributor  shall
be responsible for the distribution-related expenses as provided in paragraphs 1
and 2 hereof.

         7.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         8. This Plan shall become  effective  upon (a) approval by a vote of at
least a "majority  of the  outstanding  voting  securities"  of Class C, and (b)
approval  by a vote of the Board of  Trustees  and a vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest in the  operation of the Plan or in any  agreement
related to the Plan (the "Qualified Trustees"),  such votes to be cast in person
at a meeting called for the purpose of voting on this Plan.

         9. This Plan shall continue in effect indefinitely;  provided that such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained,  this Plan shall expire 12 months after
the effective date of the last approval.

         10.  This Plan may be  amended  at any time by the  Board of  Trustees;
provided that this Plan may not be amended to increase  materially the amount of
permitted  expenses  hereunder without the approval of holders of a "majority of
the outstanding  voting securities" of Class C and may not be materially amended
in any case without a vote of a majority of both the Trustees and the  Qualified
Trustees. This Plan may be terminated at any time by a vote of a majority of the
Qualified Trustees or by a vote of the holders of a "majority of the outstanding
voting securities" of Class C.

         11. The Fund and the  Distributor  shall provide the Board of Trustees,
and the Board of Trustees shall review, at least quarterly,  a written report of
the  amounts   expended  under  this  Plan  and  the  purposes  for  which  such
expenditures were made.

         12.  While this Plan is in effect,  the  selection  and  nomination  of
Qualified  Trustees shall be committed to the discretion of the Trustees who are
not "interested persons" of the Trust.

         13. For the  purposes  of this Plan,  the terms  "interested  persons",
"majority of the outstanding  voting  securities" and "specifically  approved at
least  annually" are used as defined in the 1940 Act. In addition,  for purposes
of determining the fees payable to the Distributor  hereunder,  the value of the
Fund's net  assets  shall be  computed  in the  manner  specified  in the Fund's
then-current  prospectus and statement of additional information for computation
of the net asset value of the Shares of the Fund.

         14. The Trust shall  preserve  copies of this Plan,  and each agreement
related hereto and each report referred to in paragraph 11 hereof (collectively,
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  record  shall be kept in an easily
accessible place for the first two years of said record-keeping.

         15. This Plan shall be  construed  in  accordance  with the laws of The
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

         16. If any  provision  of this Plan shall be held or made  invalid by a
court decision,  statute, rule or otherwise, the remainder of the Plan shall not
be affected thereby.

                              PLAN OF DISTRIBUTION


         PLAN OF DISTRIBUTION with respect to the shares of beneficial  interest
to be  designated  "CLASS B" of MFS MUNICIPAL  HIGH INCOME FUND (the "Fund"),  a
series of MFS Series Trust III (the  "Trust") a  Massachusetts  business  trust,
dated September 1, 1993 and amended this 21st day of December, 1994.

                                  WITNESSETH:

         WHEREAS,  the Trust is engaged in business  as an  open-end  management
investment  company and is registered under the Investment  Company Act of 1940,
as amended (collectively with the rules and regulations  promulgated thereunder,
the "1940 Act"); and

         WHEREAS,  the Trust  intends to  distribute  the  shares of  beneficial
interest  (without  par  value)  of the  Fund  designated  Class B  Shares  (the
"Shares") in accordance with Rule 12b-1 under the 1940 Act ("Rule  12b-1"),  and
desires to adopt this  Distribution  Plan (the "Plan") as a plan of distribution
pursuant to such Rule; and

         WHEREAS, the Trust desires for MFS Fund Distributors,  Inc., a Delaware
corporation,  to  provide  certain  distribution  services  for  the  Fund  (the
"Distributor"); and

         WHEREAS,  the Trust has  entered  into a  distribution  agreement  (the
"Distribution  Agreement")  (in a form  approved by the Board of Trustees of the
Trust in a manner  specified in such Rule 12b-1) with the  Distributor,  whereby
the Distributor will provide facilities and personnel and render services to the
Fund in connection with the offering and distribution of the Shares; and

         WHEREAS,  the Trust  recognizes and agrees that (a) the Distributor may
retain the services of firms or individuals to act as dealers (the "Dealers") of
the Shares in connection  with the offering of Shares,  and (b) the  Distributor
may make  payments  for such  services to the Dealers out of the fee paid to the
Distributor hereunder,  any deferred sales charges imposed by the Distributor in
connection  with the  repurchase  of Shares,  its  profits  or any other  source
available to it; and

         WHEREAS,  the Trust  recognizes  and agrees  that the  Distributor  may
impose  certain  deferred  sales  charges in connection  with the  repurchase of
Shares by the Fund, and the Distributor may retain (or receive from the Fund, as
the case may be) all such deferred sales charges; and

         WHEREAS, the Board of Trustees of the Trust, in considering whether the
Fund should adopt and implement this Plan, has evaluated such  information as it
deemed necessary to an informed  determination as to whether this Plan should be
adopted and implemented  and has considered such pertinent  factors as it deemed
necessary  to form the basis for a  decision  to use assets of the Fund for such
purposes,  and has  determined  that there is a reasonable  likelihood  that the
adoption and  implementation  of this Plan will benefit the Fund and its Class B
shareholders;

         NOW,  THEREFORE,  the Board of Trustees of the Trust hereby adopts this
Plan  for  the  Fund  as a plan  for  distribution  relating  to the  Shares  in
accordance with Rule 12b-1, on the following terms and conditions:

         1. As specified in the Distribution  Agreement,  the Distributor  shall
provide  facilities,  personnel  and a program  with respect to the offering and
sale of Shares.  Among other things,  the  Distributor  shall be responsible for
commissions payable to Dealers, all expenses of printing (excluding typesetting)
and  distributing  prospectuses to prospective  shareholders  and providing such
other related services as are reasonably necessary in connection therewith.

         2. The Distributor shall bear all distribution-related  expenses to the
extent  specified  in the  Distribution  Agreement  in  providing  the  services
described in paragraph 1, including  without  limitation,  the  compensation  of
personnel  necessary  to provide such  services and all costs of travel,  office
expenses  (including  rent and  overhead),  equipment,  printing,  delivery  and
mailing costs.

         3. It is understood that the  Distributor  may impose certain  deferred
sales  charges in connection  with the  repurchase of Shares by the Fund and the
Distributor  may retain (or receive from the Fund,  as the case may be) all such
deferred sales charges.  As additional  consideration for all services performed
and  expenses   incurred  in  the  performance  of  its  obligations  under  the
Distribution  Agreement,  the Fund shall pay the Distributor a distribution  fee
periodically at a rate of 0.75% per annum of the Fund's average daily net assets
attributable to the Shares.

         4. As partial  consideration  for the personal  services and/or account
maintenance  services  performed  by  each  Dealer  in  the  performance  of its
obligations under its dealer agreement with the Distributor,  the Fund shall pay
each Dealer a service fee  periodically  at a rate not to exceed 0.25% per annum
of the portion of the average  daily net assets of the Fund that is  represented
by Shares  that are owned by  investors  for whom such  Dealer is the  holder or
dealer of record.  That portion of the Fund's  average daily net assets on which
the fees payable under this  paragraph 4 hereof are calculated may be subject to
certain  minimum amount  requirements  as may be  determined,  and additional or
different  dealer  qualification  standards that may be established from time to
time, by the Distributor.  The Distributor shall be entitled to be paid any fees
payable under this paragraph 4 hereof with respect to Shares for which no Dealer
of  record  exists  or  qualification  standards  have not  been met as  partial
consideration for personal services and/or account maintenance services provided
by the  Distributor  to the Shares.  The  service  fee payable  pursuant to this
paragraph 4 may from time to time be paid by the Fund to the Distributor and the
Distributor will then pay these fees on behalf of the Fund.

         5. The Fund understands that agreements between the Distributor and the
Dealers may provide for payment of commissions to Dealers in connection with the
sales of Shares and may provide for a portion (which may be all or substantially
all) of the fees payable by the Fund to the Distributor  under the  Distribution
Agreement to be paid by the Distributor to the Dealers in  consideration  of the
Dealer's services as a dealer of the Shares. Except as described in paragraph 4,
nothing  in this  Plan  shall be  construed  as  requiring  the Fund to make any
payment to any  Dealer or to have any  obligations  to any Dealer in  connection
with  services  as a dealer  of the  Shares.  The  Distributor  shall  agree and
undertake that any agreement entered into between the Distributor and any Dealer
shall  provide  that,  except as provided in paragraph 4, such Dealer shall look
solely to the Distributor for compensation for its services  thereunder and that
in no event shall such Dealer seek any payment from the Fund.

         6. The Fund shall pay all fees and expenses of any independent auditor,
legal counsel,  investment adviser,  administrator,  transfer agent,  custodian,
shareholder servicing agent, registrar or dividend disbursing agent of the Fund;
expenses  of  distributing  and  redeeming  Shares  and  servicing   shareholder
accounts; expenses of preparing, printing and mailing prospectuses,  shareholder
reports,  notices,  proxy  statements and reports to  governmental  officers and
commissions and to shareholders of the Fund,  except that the Distributor  shall
be responsible for the distribution-related expenses as provided in paragraphs 1
and 2 hereof.

         7.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         8. This Plan shall become  effective  upon (a) approval by a vote of at
least a "majority of the outstanding  voting  securities" of the Shares, and (b)
approval  by a vote of the Board of  Trustees  and a vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest in the  operation of the Plan or in any  agreement
related to the Plan (the "Qualified Trustees"),  such votes to be cast in person
at a meeting called for the purpose of voting on this Plan.

         9. This Plan shall continue in effect indefinitely;  provided that such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained,  this Plan shall expire 12 months after
the effective date of the last approval.

         10.  This Plan may be  amended  at any time by the  Board of  Trustees;
provided that this Plan may not be amended to increase  materially the amount of
permitted  expenses  hereunder without the approval of holders of a "majority of
the  outstanding  voting  securities"  of the Shares  and may not be  materially
amended in any case  without a vote of a majority of both the  Trustees  and the
Qualified  Trustees.  This  Plan  may be  terminated  at any time by a vote of a
majority of the Qualified Trustees or by a vote of the holders of a "majority of
the outstanding voting securities" of the Shares.

         11. The Fund and the  Distributor  shall provide the Board of Trustees,
and the Board of Trustees shall review, at least quarterly,  a written report of
the  amounts   expended  under  this  Plan  and  the  purposes  for  which  such
expenditures were made.

         12.  While this Plan is in effect,  the  selection  and  nomination  of
Qualified  Trustees shall be committed to the discretion of the Trustees who are
not "interested persons" of the Trust.

         13. For the  purposes  of this Plan,  the terms  "interested  persons",
"majority of the outstanding  voting  securities" and "specifically  approved at
least  annually" are used as defined in the 1940 Act. In addition,  for purposes
of determining the fees payable to the Distributor  hereunder,  the value of the
Fund's net  assets  shall be  computed  in the  manner  specified  in the Fund's
then-current  prospectus and statement of additional information for computation
of the net asset value of the Shares of the Fund.

         14. The Trust shall  preserve  copies of this Plan,  and each agreement
related hereto and each report referred to in paragraph 11 hereof (collectively,
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  record  shall be kept in an easily
accessible place for the first two years of said record-keeping.

         15. This Plan shall be  construed  in  accordance  with the laws of The
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

         16. If any  provision  of this Plan shall be held or made  invalid by a
court decision,  statute, rule or otherwise, the remainder of the Plan shall not
be affected thereby.
