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

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

     Class A shares of the Fund may be  purchased  at net asset value by certain
retirement plans subject to the Employee Retirement Income Security Act of 1974,
as amended, subject to the following:

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

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

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

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

     Class  A  shares  of the  Fund  may be  purchased  at net  asset  value  by
retirement  plans  whose  third  party   administrators  have  entered  into  an
administrative  services  agreement with MFD or one or more of its affiliates to
perform  certain  administrative   services,   subject  to  certain  operational
requirements  specified  from  time  to  time  by  MFD or  one  or  more  of its
affiliates.
                -----------------------------------------------
                                                                          (Over)
<PAGE>
     Class A  shares  of the  Fund  (except  of the  MFS  municipal  bond  funds
identified  above)  may be  purchased  at net asset  value by  retirement  plans
qualified  under Section 401(k) of the Code through certain  broker-dealers  and
other financial institutions which have entered into an agreement with MFD which
includes  certain  minimum size  qualifications  for such  retirement  plans and
provides that the  broker-dealer  or other  financial  institution  will perform
certain administrative services with respect to the plan's account.

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

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

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

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

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

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

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

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

     From time to time, MFD may pay dealers 100% of the applicable  sales charge
on sales of Class A shares of certain specified Funds sold by such dealer during
a specified sales period.  In addition,  MFD or its affiliates may, from time to
time, pay dealers an additional commission equal to 0.50% of the net asset value
of all of the Class B shares of  certain  specified  Funds  sold by such  dealer
during a specified sales period.

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

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

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

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

                THE DATE OF THIS SUPPLEMENT IS JANUARY 13, 1995.

This Prospectus pertains to the MFS Bond Fund (the "Fund"), a diversified series
of MFS(R) Fixed  Income  Trust (the  "Trust"),  an open-end  investment  company
presently  consisting of three series. The primary  investment  objective of the
MFS Bond Fund is to provide as high a level of current  income as is believed to
be consistent with prudent investment risk. The secondary  objective of the Fund
is to protect shareholders'  capital. See "Investment  Objectives and Policies."
The  minimum   initial   investment   is  generally   $1,000  per  account  (see
"Purchases").

The investment  adviser and distributor of the Fund are Massachusetts  Financial
Services Company and MFS Financial Services, Inc.,  respectively,  both of which
are located at 500 Boylston Street,  Boston,  Massachusetts 02116.

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

This Prospectus  sets forth  concisely the information  concerning the Trust and
the Fund that a prospective  investor ought to know before investing.  The Trust
on behalf of the Fund has filed  with the  Securities  and  Exchange  Commission
("SEC") a  Statement  of  Additional  Information,  dated  July 1,  1994,  which
contains  more  detailed  information  about  the  Fund  and  the  Trust  and is
incorporated  into  this  Prospectus  by  reference.  See page 28 for a  further
description  of the  information  set  forth  in  the  Statement  of  Additional
Information.  A copy of the Statement of Additional  Information may be obtained
without charge by contacting the Shareholder Servicing Agent (see back cover for
address and phone number).

   INVESTORS SHOULD READ THIS PROSPECTUS AND RETAIN IT FOR FUTURE REFERENCE.

1.  THE FUND
MFS Bond Fund (the  "Fund") is a  diversified  series of MFS Fixed  Income Trust
(the "Trust"),  an open-end management investment company which was organized as
a trust under the laws of The  Commonwealth of  Massachusetts in 1985. The Trust
presently  consists of three series,  each of which  represents a portfolio with
separate  policies.  Shares of the Fund are continuously  sold to the public and
the Fund uses the proceeds to buy securities for its portfolio. Three classes of
shares of the Fund currently are offered to the general  public.  Class A shares
are offered at net asset  value plus an initial  sales  charge (or a  contingent
deferred sales charge (a "CDSC") in the case of certain  purchases of $1 million
or more) and subject to a Distribution Plan providing for an annual distribution
fee and service  fee.  Class B shares are offered at net asset value  without an
initial sales charge but subject to a CDSC and a Distribution Plan providing for
an annual  distribution  fee and service fee which are greater  than the Class A
distribution  fee and service fee. Class B shares will convert to Class A shares
approximately  eight  years  after  purchase.  Class C shares are offered at net
asset value without a 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  fee and service fee. Class C shares do not convert
to any other class of shares of the Fund.

The Trust's Board of Trustees provides broad supervision over the affairs of the
Fund. Massachusetts Financial Services Company, a Delaware corporation ("MFS" or
the "Adviser"), is the Fund's investment adviser. A majority of the Trustees are
not affiliated  with the Adviser.  The Adviser is responsible for the management
of the  Fund's  assets and the  officers  of the Trust are  responsible  for the
Fund's  operations.  The  Adviser  manages  the  portfolio  from  day  to day in
accordance  with  the  investment  objectives  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 Trust also offers
to buy back (redeem) the Fund's shares from Fund shareholders at any time at net
asset value, less any applicable CDSC.

    Total Operating Expenses (after applicable fee

<FN>
- ---------
<F1> Purchases of $1 million or more are not subject to an initial sales charge;
     however,  a CDSC of 1% will be  imposed on such  purchases  in the event of
     certain redemption  transactions  within 12 months following such purchases
     (see "Purchases" 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.
<F4> Except for the shareholder servicing agent fee component,  "Other Expenses"
     is based on Class A expenses  incurred  during the fiscal  year ended April
     30, 1994. The shareholder servicing agent fee component of "Other Expenses"
     is a predetermined percentage based upon the Fund's net assets attributable
     to each class.
<F5> Absent  the  Distribution  Plan fee  waiver,  the Fund's  "Total  Operating
     Expenses"  for Class A shares  would have been 1.05% of average  net assets
     attributable  to that  class.

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

       1 year     .............   $ 57         $ 58         $ 18         $ 17
       3 years     ............     76           86           56           54
       5 years     ............     98          117           97           93
      10 years     ............    159          188(2)       188(2)       203
     ---------

(1) Assumes no redemption.

(2) Class B shares  convert to Class A shares  approximately  eight  years after
    purchase; therefore, years nine and ten reflect Class A expenses.

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

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

     fee  attributable  to Class A shares  amounting  to $0.01 per share for the
     year ended April 30, 1994. If these expenses had been incurred by the Fund,
     the ratios of expenses and net investment  income to average net assets for

4.  INVESTMENT OBJECTIVES AND POLICIES
INVESTMENT  OBJECTIVES -- The Fund's primary investment  objective is to provide
as high a level of current  income as is believed to be consistent  with prudent
investment  risk.  The Fund's  secondary  objective is to protect  shareholders'
capital.  Any  investment  involves risk and there can be no assurance  that the
Fund will achieve its investment objectives.

INVESTMENT POLICIES -- Under normal market conditions,  all investments are made
in accordance with the following policies:

    1. Approximately  80% of the  Fund's  net assets  will be  invested  in:

       (a)  non-convertible  debt securities which have a rating within the four
       highest  grades as determined by Standard & Poor's  Ratings Group ("S&P")
       (AAA, AA, A or BBB) or Moody's Investors Service,  Inc. ("Moody's") (Aaa,
       Aa, A or Baa) and  comparable  unrated  securities;  for a description of
       these rating categories, see Appendix A to this Prospectus;

       (b) debt  securities  issued or guaranteed by the United States  ("U.S.")
       Government  or its  agencies,  authorities  or  instrumentalities  ("U.S.
       Government Securities");

       (c)  non-convertible  debt securities issued or guaranteed by national or
       state banks or bank  holding  companies  (as defined in the Federal  Bank
       Holding  Company Act) which,  although not rated as a matter of policy by
       S&P or  Moody's,  are  considered  by the  Adviser to have an  investment
       quality  equivalent to securities  which may be purchased  under item (a)
       above; or

       (d) commercial paper,  repurchase agreements and cash or cash equivalents
       (such as certificates of deposit and bankers' acceptances).

    2. Up to 20% of the Fund's total  assets may be invested in  non-convertible
       debt securities which are not rated within the four highest grades of S&P
       or Moody's as described above and comparable unrated securities (commonly
       known as "junk bonds") and in convertible  debt  securities and preferred
       stocks.  These  convertible  debt securities and preferred  stocks may be
       unrated  or  rated  below  the four  highest  grades  of S&P and  Moody's
       described  above.  For a  description  of these ratings see Appendix A to
       this Prospectus and for a chart  indicating the composition of the Fund's
       portfolio  for the  fiscal  year  ended  April  30,  1994  with  the debt
       securities rated by S&P separated into rating categories,  see Appendix B
       to this  Prospectus.  For a discussion of the risks of investing in these
       securities see "Risks of Investing in Lower Rated Bonds" below.

Although the Fund may  purchase  Canadian and other  foreign  securities,  under
normal  market  conditions,  it may not  invest  more than 10% of its  assets in
non-dollar denominated non-Canadian foreign securities.

The Fund may not directly purchase common stocks.  However,  the Fund may retain
up to 10% of its total  assets in common  stocks which were  acquired  either by
conversion of fixed income  securities  or by the exercise of warrants  attached
thereto.

U.S.  Government  Securities  also include  interest in trusts or other entities
representing  interests in obligations that are issued or guaranteed by the U.S.
Government, its agencies, authorities or instrumentalities.

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.  The  underlying
assets  (e.g.,  loans)  are  also  subject  to  prepayments  which  shorten  the
securities' weighted average life and may lower their return.

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 on  underlying  assets to make  payments,  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  investment in such a
security.

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.

Payment of principal and interest on some mortgage pass-through  securities (but
not the market value of the securities themselves) may be guaranteed by the full
faith and credit of the U.S. Government (in the case of securities guaranteed by
the  Government  National  Mortgage  Association  ("GNMA"));  or  guaranteed  by
agencies  or  instrumentalities  of the U.S.  Government  (such  as the  Federal
National  Mortgage  Association  ("FNMA")  or the  Federal  Home  Loan  Mortgage
Corporation ("FHLMC"),  which are supported only by the discretionary  authority
of  the  U.S.  Government  to  purchase  the  agency's  obligations).   Mortgage
pass-through securities may also be issued by non-governmental  issuers (such as
commercial  banks,  savings and loan  institutions,  private mortgage  insurance
companies,  mortgage bankers and other secondary market issuers).  Some of these
mortgage pass-through  securities may be supported by various forms of insurance
or guarantees.

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

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.

Swaps, caps, floors and collars are highly specialized  activities which involve
certain  risks  different  from  those   associated   with  ordinary   portfolio
transactions.   See  the  Statement  of  Additional   Information   for  further
information on, and 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  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 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.  The Fund will  continue  to collect the  equivalent  of interest on the
securities loaned and will also receive either interest  (through  investment of
cash collateral) or a fee (if the collateral is government  securities).  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.

ZERO  COUPON  BONDS,  DEFERRED  INTEREST  BONDS  AND  PIK  BONDS:  Fixed  income
securities in which the Fund may invest also include zero coupon bonds, deferred
interest bonds and bonds on which the interest is payable in kind ("PIK bonds").
Zero coupon and deferred interest bonds are debt obligations which are issued or
purchased at a significant  discount from face value. The discount  approximates
the total amount of interest the bonds will accrue and compound  over the period
until  maturity  or the  first  interest  payment  date,  at a rate of  interest
reflecting  the market rate of the security at the time of issuance.  While zero
coupon bonds do not require the periodic payment of interest,  deferred interest
bonds  provide  for a period of delay  before the  regular  payment of  interest
begins.  PIK bonds are debt  obligations  which provide that the issuer  thereof
may,  at its  option,  pay  interest  on such  bonds  in cash or in the  form of
additional debt obligations.  Such investments  benefit the issuer by mitigating
its need for cash to meet debt service, but also require a higher rate of return
to  attract  investors  who are  willing to defer  receipt  of such  cash.  Such
investments may experience  greater volatility in market value due to changes in
interest rates than debt  obligations  which make regular  payments of interest.
The Fund will accrue income on such investments for tax and accounting purposes,
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
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  referred  to as  "Mortgage  Assets").  The Fund may also  invest a
portion of its assets in multiclass  pass-through securities which are interests
in  a  trust  composed  of  Mortgage  Assets.  CMOs  (which  include  multiclass
pass-through  securities) may be issued by agencies or  instrumentalities of the
U.S.  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.  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.  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 "tranche", 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 part of the premium if any has
been paid. Certain classes of CMOs have priority over others with respect to the
receipt of  prepayments on the  mortgages.  Therefore,  depending on the type of
CMOs in which the Fund invests,  the  investment  may be subject to a greater or
lesser risk of prepayments than other types of mortgage-related securities.

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, parallel pay CMOs and PAC Bonds and
the risks  related to  transactions  therein,  see the  Statement of  Additional
Information.

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

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

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

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

OPTIONS:  The Fund  intends to write (sell)  "covered"  put and call options and
purchase 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
security 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 security,  and put options are "covered" by
the Fund,  for example,  when it has  established a segregated  account of cash,
short-term money market instruments or high quality debt securities which can be
liquidated  promptly  to satisfy  any  obligation  of the Fund to  purchase  the
underlying security. The Fund may also write straddles (combinations of puts and
calls on the same underlying  security).  The writing of straddles  provides the
Fund with  additional  premium  income,  but could involve greater risk. See the
Statement of Additional Information.

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  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.  Over-the-counter  transactions  also
involve certain risks which may not be present in an exchange environment.

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 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 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 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
part 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 such SEC illiquidity ceiling.

FUTURES  CONTRACTS AND OPTIONS ON FUTURES  CONTRACTS:  The Fund may purchase and
sell futures contracts on foreign or domestic fixed income securities or indices
of such  securities,  including  municipal bond indices and any other indices of
foreign or domestic  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 only 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  under  applicable  law,  which
involves  greater risks and could result in losses which are not offset by gains
on other portfolio assets.

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") for hedging purposes only. 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 will enter into  Forward  Contracts  for
hedging  purposes  to  attempt  to  minimize  the risk to the Fund from  adverse
changes in the relationship  between the U.S. dollar and foreign  currency.  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.  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 may choose to, or be
required  to,  receive  delivery of the foreign  currencies  underlying  Forward
Contracts it has entered into.  Under certain  circumstances,  such as where the
Adviser  believes that the  applicable  exchange rate is unfavorable at the time
the  currencies are received or the Adviser  anticipates,  for any other reason,
that the exchange rate will improve,  the Fund may hold such  currencies  for an
indefinite period of time. The Fund 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 "Risks
of Investing in Foreign Securities" for information on the risks associated with
holding foreign currency.

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  choose to, or be  required  to,  receive  delivery of the foreign
currencies  underlying  options on foreign currencies it has entered into. Under
certain  circumstances,  such as where the Adviser  believes that the applicable
exchange  rate is  unfavorable  at the time the  currencies  are received or the
Adviser anticipates,  for any other reason, that the exchange rate will improve,
the Fund may hold such  currencies for an indefinite  period of time. See "Risks
of  Investing  in  Foreign  Securities,"  below  for  information  on the  risks
associated with holding foreign currency.

SPECIAL  CONSIDERATIONS:  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,  and will enter into
certain other  options  transactions  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 such instruments for other than hedging purposes, which involves
greater risk. In particular, such transactions may result in losses for the Fund
which are not offset by gains on other  portfolio  positions,  thereby  reducing
gross income.  In addition,  foreign currency markets may be extremely  volatile
from time to time. There 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  in  options  may be  entered  into by the  Fund on U.S.  exchanges
regulated by the SEC, in the  over-the-counter  market and on foreign exchanges,
while Forward Contracts may be entered into only in the over-the-counter market.
Futures  Contracts and Options on Futures  Contracts may be entered into on U.S.
exchanges  regulated  by the CFTC and on foreign  exchanges.  In  addition,  the
securities  underlying  options  and Futures  Contracts  traded by the Fund will
include foreign as well as domestic securities.

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 with the
general level of interest rates.  When interest rates decline,  the market value
of a portfolio  invested at higher  yields can be expected to rise.  Conversely,
when  interest  rates rise,  the market  value of a portfolio  invested at lower
yields can be expected to decline.

RISKS OF INVESTING IN LOWER RATED BONDS: As indicated  above,  the Fund may also
invest up to 20% of its total assets in securities  rated Ba or lower by Moody's
or BB or lower by S&P 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.  However,  since yields vary over time, no specific  level of income
can ever be assured.  These lower rated high  yielding  fixed income  securities
generally tend to reflect economic changes and short-term corporate and industry
developments  to a greater  extent  than  higher  rated  securities  which react
primarily to fluctuations  in the general level of interest  rates.  These lower
rated fixed income  securities  are also affected by changes in interest  rates,
the market's  perception of their credit  quality,  and the outlook for economic
growth. In the past,  economic  downturns or an increase in interest rates have,
under certain circumstances, caused a higher incidence of default by the issuers
of  these  securities  and may do so in the  future,  especially  in the case of
highly  leveraged  issuers.  During  certain  periods,  the higher yields on the
Fund's lower rated high  yielding  fixed income  securities  are paid  primarily
because of the increased risk of loss of principal and income, arising from such
factors as the heightened possibility of default or bankruptcy of the issuers of
such securities.  Due to the fixed income payments of these securities, the Fund
may continue to earn the same level of interest income while its net asset value
declines  due to  portfolio  losses,  which  could  result in an increase in the
Fund's yield  despite the actual loss of  principal.  The market for these lower
rated fixed income  securities may be less liquid than the market for investment
grade fixed income securities.  Therefore,  judgment may at times play a greater
role in valuing  these  securities  than in the case of  investment  grade fixed
income securities.

The Fund may also invest in fixed income  securities rated Baa by Moody's or BBB
by S&P and  comparable  unrated  securities.  These  securities,  while normally
exhibiting adequate protection parameters,  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.

These lower rated and comparable unrated securities may also include zero coupon
bonds, deferred interest bonds and PIK bonds, described above. See the Statement
of Additional Information for more information on lower rated securities.

RISKS OF  INVESTING  IN  FOREIGN  SECURITIES:  The Fund may  invest  in  foreign
securities  to the extent  described  above.  Investing in securities of foreign
issuers  generally  involves risks not ordinarily  associated  with investing in
securities of domestic  issuers.  These risks include changes in currency rates,
exchange  control  regulations,   governmental  administration  or  economic  or
monetary  policy (in the U.S. 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
U.S.investments  in  foreign  countries  could  be  affected  by  other  factors
including  expropriation,  confiscatory  taxation and potential  difficulties in
enforcing  contractual  obligations and could be subject to extended  settlement
periods.  The  Fund  may hold  foreign  currency  received  in  connection  with
investments in foreign securities when, in the judgment of the Adviser, it would
be beneficial to convert such currency into U.S.  dollars at a later date, based
on  anticipated  changes in the relevant  exchange  rate. The Fund may also hold
foreign  currency in  anticipation  of purchasing  foreign  securities.  See the
Statement of Additional Information for further discussion of foreign securities
and the holding of foreign currency, as well as the associated risks.

RESTRICTED  SECURITIES:  The  Fund  may also  purchase  securities  that are not
registered   under  the   Securities  Act  of  1933,  as  amended  ("1933  Act")
("restricted  securities"),  including  those  that can be  offered  and sold to
"qualified  institutional buyers" under Rule 144A under the 1933 Act ("Rule 144A
securities").  The Trust's Board of Trustees determines, based upon a continuing
review of the trading  markets for a specific Rule 144A  security,  whether such
security is illiquid and thus subject to the Fund's  limitation on investing not
more than 10% 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  these Rule 144A securities
held  in  the  Fund's  portfolio.  Subject  to  the  Fund's  10%  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.

PORTFOLIO  TRADING:  The Fund intends to engage in portfolio trading rather than
holding 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.  For a  description  of  the
strategies which may be used by the Fund in trading  portfolio  securities,  see
"Portfolio  Trading" in the  Statement of  Additional  Information.

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 MFS Financial  Services,  Inc. ("FSI"),  the
Fund's  distributor,  as a factor in the selection of  broker-dealers to execute
the Fund's portfolio transactions.

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

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

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

5. MANAGEMENT OF THE FUND
INVESTMENT  ADVISER -- The Adviser manages the assets of the Fund pursuant to an
Investment   Advisory   Agreement,   dated   December  2,  1985  (the  "Advisory
Agreement").  The Adviser provides the Fund with overall investment advisory and
administrative  services,  as well as general  office  facilities.  Geoffrey  L.
Kurinsky,  a Senior Vice President of the Adviser, has been the Fund's portfolio
manager since 1989 and has been  employed by the Adviser since 1987.  Subject to
such  policies as the  Trustees  may  determine,  the Adviser  makes  investment
decisions for the Fund. For these services and facilities,  the Adviser receives
a management  fee,  computed and paid  monthly  fixed by a formula  based upon a
percentage of the Fund's  average daily net assets for its  then-current  fiscal
year plus a percentage of the Fund's gross income (i.e., income other than gains
from the sale of  securities,  gains from options and futures  transactions  and
premium  income from  options  written)  for that fiscal  year.  The  applicable
percentages are reduced as assets and income attain the following levels:

ANNUAL RATE OF MANAGEMENT FEE               ANNUAL RATE OF MANAGEMENT FEE
BASED ON AVERAGE DAILY NET ASSETS           BASED ON GROSS INCOME
- ---------------------------------           -----------------------------
.225% of the first $200 million             2.75% of the first $20 million
.191% of average daily net assets           2.34% of gross  income in 
   in excess of $200  million                 excess of $20  million

For the Fund's fiscal year ended April 30, 1994,  MFS received  management  fees
under the Advisory  Agreement of $2,114,447  (of which  $1,049,828  was based on
average  daily net assets and  $1,064,619  on gross  income),  equivalent  on an
annualized basis to 0.41% of the Fund's average daily net assets.

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

MFS is  America's  oldest  mutual  fund  organization.  MFS and its  predecessor
organizations  have a  history  of money  management  dating  from  1924 and the
founding of the first mutual fund in the United States,  Massachusetts Investors
Trust.   Net  assets  under  the  management  of  the  MFS   organization   were
approximately  $33.8  billion on behalf of  approximately  1.5 million  investor
accounts  as of May 31,  1994.  As of such date,  the MFS  organization  managed
approximately $19.4 billion of net assets in fixed income funds and fixed income
portfolios of the MFS Asset Management Group. MFS is a subsidiary of Sun Life of
Canada (U.S.),  which in turn is a subsidiary of Sun Life  Assurance  Company of
Canada  ("Sun  Life").  The  Directors of MFS are A. Keith  Brodkin,  Jeffrey L.
Shames,  Arnold D. Scott, John R. Gardner and John D. McNeil, Mr. Brodkin is the
Chairman,  Mr.  Shames is the  President  and Mr. Scott is the  Secretary  and a
Senior  Executive  Vice  President  of MFS.  Messrs.  McNeil and Gardner are the
Chairman and 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 U.S.  since 1895,  establishing  a  headquarters
office  here in 1973.  The  executive  officers  of MFS report  directly  to the
Chairman of Sun Life.

A. Keith Brodkin, the Chairman and a Director of MFS, is the Chairman, President
and a Trustee of the Trust. W. Thomas London,  Stephen E. Cavan, Linda J. Hoard,
James R.  Bordewick,  Jr.,  James O.  Yost,  Robert A.  Dennis and  Geoffrey  L.
Kurinsky, all of whom are officers of MFS, are officers of the Trust.

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

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

6.  INFORMATION CONCERNING SHARES OF THE FUND

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

The  Fund  offers  three   classes  of  shares  which  have  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. FSI (on behalf of the Fund) will
     pay a commission on purchases of $1 million or more.
</TABLE>

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

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

FSI allows  discounts  to dealers  (which  are alike for all  dealers)  from the
applicable  public  offering  price, as shown in the above table. In the case of
the maximum sales charge,  the dealer  retains 4% and FSI retains  approximately
3/4 of 1% of the public  offering price.  In addition,  FSI pays  commissions to
dealers who initiate and are  responsible for purchases of $1 million or more as
follows:  1.00% on sales up to $5 million, plus 0.25% on the amount in excess of
$5 million. 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. 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.  Class A shares of the Fund may be sold at their net asset value to
the officers of the Trust,  to any of the  subsidiary  companies of Sun Life, to
eligible Directors, officers, employees (including retired employees) and agents
of MFS, Sun Life or any of their subsidiary  companies,  to any trust,  pension,
profit-sharing  or any other benefit plan for such persons,  to any trustees and
retired  trustees of any investment  company for which FSI serves as distributor
or principal underwriter,  and to certain family members of such individuals and
their spouses, provided such shares will not be resold except to the Fund.

Class A  shares  of the  Fund may be sold at net  asset  value to any  employee,
partner,  officer or trustee of any  sub-adviser  to any MFS Fund and to certain
family members of such individuals and their spouses, or to any trust,  pension,
profit-sharing or other retirement plan for the sole benefit of such employee or
representative,  provided  such  shares  will not be resold  except to the Fund.
Class A shares  of the Fund may  also be sold at their  net  asset  value to any
employee  or  registered   representative  of  any  dealer  or  other  financial
institution  which has a sales agreement with FSI or its affiliates,  to certain
family members of such employees or representatives and their spouses, or to any
trust, pension,  profit-sharing or other retirement plan for the sole benefit of
such  employee  or  representative,  as well  as to  clients  of the  MFS  Asset
Management Group.  Insurance company separate accounts may also purchase Class A
shares of the Fund at their net asset value. Class A shares of the Fund also may
be sold at net asset  value,  subject to  appropriate  documentation,  through a
dealer  where  the  amount  invested  represents   redemption  proceeds  from  a
registered open-end management  investment company not distributed or managed by
FSI or its  affiliates,  if such  redemption  has  occurred no more than 60 days
prior to the purchase of Class A shares of the Fund and the  shareholder  either
(i) paid an initial  sales  charge or (ii) was at some time  subject to, but did
not  actually  pay, a  deferred  sales  charge  with  respect to the  redemption
proceeds.  Class A shares of the Fund may also be sold at net asset  value where
the amount  invested  represents  redemption  proceeds of 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 the  liquidation  of the  assets  of other
investment  companies or personal holding companies.  Class A shares of the Fund
may be purchased at their net asset value by retirement  plans where third party
administrators of such plans have entered into certain  arrangements with FSI or
its affiliates provided that no commission is paid to dealers. Class A shares of
the Fund may be purchased at net asset value through certain  broker-dealers and
other  financial  institutions  which have entered  into an agreement  with FSI,
which includes a requirement that such shares be sold for the benefit of clients
participating  in a "wrap account" or a similar program under which such clients
pay a fee to such broker-dealer or other financial institution.

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

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

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

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

Dealers who initiate and are  responsible for purchases of Class A shares of the
Fund in this manner will be paid a commission by FSI, as follows: 1.00% on sales
up to $5 million,  plus 0.25% on the amount in excess of $5  million;  provided,
however,  that FSI may pay a  commission,  on sales in excess of $5  million  to
certain   retirement  plans,  of  1.00%  to  certain  dealers  which,  at  FSI's
invitation,  enter  into an  agreement  with FSI in which the  dealer  agrees to
return any commission paid to it on the sale (or on a pro rata portion  thereof)
if the  shareholder  redeems  his or her  shares  within a period of time  after
purchase  as  specified  by  FSI.  Purchases  of $1  million  or more  for  each
shareholder  account will be aggregated over a 12-month period  (commencing from
the date of the first such  purchase) for purposes of  determining  the level of
commissions to be paid during that period with respect to such account.  Class A
shares of the Fund may also be sold at net asset  value  through  the  automatic
reinvestment  of Class A and Class B  distributions  which  constitute  required
withdrawals from qualified retirement plans. Class A shares of the Fund may also
be purchased at net asset value where the purchase is in an amount of $3 million
or more and where the dealer and FSI enter into an agreement in which the dealer
agrees to return any commission paid to it on the sale (or on a pro rata portion
thereof) as described above if the shareholder  redeems his or her shares within
one year of  purchase.  (Shareholders  who  purchase  shares at net asset  value
pursuant to these conditions are called "$3 Million Shareholders"). Furthermore,
Class A shares of the Fund may be sold at net asset value  through the automatic
reinvestment of  distributions  of dividends and capital gains of Class A shares
of  other  MFS  Funds  pursuant  to the  Distribution  Investment  Program  (see
"Shareholder  Services" in the  Statement of  Additional  Information).

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

      YEAR OF                                                       CONTINGENT

*Class B shares  purchased  from  January 1, 1993 through  August 31, 1993,  are
 subject  to a CDSC of 5% in the event of a  redemption  within  the first  year
 after purchase.
For Class B shares  purchased  prior to January 1, 1993, the Fund imposes a CDSC
as a percentage of redemption proceeds as follows:
       YEAR OF                                                       CONTINGENT

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" below for further discussion of the CDSC.

The CDSC on Class B shares  will be  waived  upon the  death or  disability  (as
defined in section  72(m)(7) of the Code) of any investor,  provided the account
is registered (i) in the case of a deceased  individual,  solely in the deceased
individual's name, (ii) in the case of a disabled individual,  solely or jointly
in the disabled individual's name or (iii) in the name of a living trust for the
benefit of the deceased or disabled individual.  The CDSC on Class B shares will
also be waived in the case of  redemptions  of shares of the Fund  pursuant to a
systematic  withdrawal  plan.  In  addition,  the CDSC on Class B shares will be
waived in the case of distributions from an IRA, SAR-SEP or any other retirement
plan qualified under section 401(a),  401(k) or 403(b) of the Code, due to death
or disability,  or in the case of required minimum  distributions  from any such
retirement plan due to attainment of age 70 1/2. The CDSC on Class B shares will
be waived in the case of  distributions  from a retirement  plan qualified under
Section  401(a) of the Code due to (i)  returns  of excess  contribution  to the
plan, (ii)  retirement of a participant in the plan,  (iii) a 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 employees) and
agents of MFS, Sun Life or any of their  subsidiary  companies,  (iv) any trust,
pension,  profit-sharing  or any other  benefit plan for such  persons,  (v) any
trustees and retired trustees of any investment  company for which FSI serves as
distributor  or principal  underwriter,  and (vi) certain family members of such
individuals and their spouses, provided in each case that the shares will not be
resold except to the Fund. The CDSC on Class B shares will also be waived in the
case of redemptions by any employee or registered  representative  of any dealer
or other financial  institution which has a sales agreement with FSI, by certain
family members of any such employee or  representative  and their spouse, by any
trust, pension,  profit-sharing or other retirement plan for the sole benefit of
such  employee  or  representative  and by clients  of the MFS Asset  Management
Group.  A  retirement  plan  qualified  under  section  401(a)  of the  Code  (a
"Retirement Plan") that has invested its assets in Class B shares of one or more
of the MFS Funds for more than 10 years  from the later to occur of (i)  January
1, 1993 or (ii) the date the Retirement Plan first invests its assets in Class B
shares  of one or more of the MFS  Funds  will  have  the CDSC on Class B shares
waived  in  the  case  of a  redemption  of all  the  Retirement  Plan's  shares
(including  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 may also be waived in connection with
the  acquisition or liquidation of the assets of other  investment  companies or
personal holding companies.

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

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

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

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

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

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

Purchases and exchanges  should be made for  investment  purposes only. The Fund
and FSI each  reserve  the right to reject  any  specific  purchase  order or to
restrict purchases by a particular  purchaser (or group of related  purchasers).
The Fund or FSI may reject or restrict any  purchases of the Fund's  shares 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
management of the Fund.

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

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

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

EXCHANGES
Subject to the  requirements  set forth  below,  some or all of the shares in an
account with the Fund for which payment has been received by the Fund (i.e.,  an
established account) may be exchanged for the same class of shares of any of the
other MFS Funds (if available for sale) at net asset value. In addition, Class C
shares may be  exchanged  for shares of 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 MFS Service  Center,  Inc.) or all the
shares in the account.  If the Exchange  Request is received by the  Shareholder
Servicing Agent on any business day prior to the close of regular trading on the
New York Stock  Exchange (the  "Exchange"),  the exchange  usually will occur on
that day if all the requirements set forth above have been complied with at that
time.  No more than five  exchanges  may be made in any one Exchange  Request by
telephone.   Additional  information  concerning  this  exchange  privilege  and
prospectuses  for any of the other MFS Funds  may be  obtained  from  investment
dealers or the  Shareholder  Servicing  Agent.  A  shareholder  should  read the
prospectus of the other MFS Fund and consider the  differences in objectives and
policies before making any exchanges.  For federal and (generally)  state income
tax  purposes,  an  exchange is treated as a sale of the shares  exchanged  and,
therefore,  an exchange could result in a gain or loss to the shareholder making
the exchange.  Exchanges by telephone are  automatically  available to most non-
retirement  plan  accounts and certain  retirement  plan  accounts.  For further
information  regarding  exchanges by telephone,  see "Redemptions by Telephone."
The exchange  privilege (or any aspect of it) may be changed or discontinued and
is subject to certain  limitations,  including certain restrictions on purchases
by market timers.  Special procedures,  privileges and restrictions with respect
to exchanges may apply to market timers who enter into an agreement with FSI, as
set forth in such agreement. (see "Purchases").

REDEMPTIONS AND REPURCHASES
A  shareholder  may  withdraw all or any portion of the amount in his account on
any date on which the Fund is open for business by redeeming shares at their net
asset  value  or by  selling  such  shares  to the  Fund  through  a  dealer  (a
repurchase).  Certain purchases may, however,  be subject to a CDSC in the event
of certain  redemption  transactions  (see  "Contingent  Deferred  Sales Charge"
below). For the convenience of shareholders, the Fund has arranged for different
procedures for redemption and repurchase. Since the net asset value of shares of
the  account   fluctuate,   redemptions  or   repurchases,   which  are  taxable
transactions, are likely to result in gains or losses to the shareholder. When a
shareholder  withdraws an amount from his account,  the shareholder is deemed to
have tendered for redemption a sufficient  number of full and fractional  shares
in his account to cover the amount  withdrawn.  The proceeds of a redemption  or
repurchase will normally be available  within seven days. For shares  purchased,
or received in exchange  for shares  purchased,  by check  (including  certified
checks or cashier's checks),  payment of redemption  proceeds may be delayed for
15 days  from the  purchase  date in an effort  to  assure  that such  check has
cleared.  Payment of redemption  proceeds may be delayed for up to seven days if
the Fund  determines  that such a delay would be in the best interest of all its
shareholders.

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

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

C. REPURCHASE THROUGH A DEALER -- If a shareholder desires to sell his shares at
net asset value through his securities  dealer (a  repurchase),  the shareholder
can place a repurchase  order with his dealer,  who may charge the shareholder a
fee. Net asset value is  calculated  on the day the dealer places the order with
FSI, as the Fund's agent. IF THE DEALER RECEIVES THE  SHAREHOLDER'S  ORDER PRIOR
TO THE CLOSE OF REGULAR TRADING ON THE NEW YORK STOCK EXCHANGE AND  COMMUNICATES
IT TO FSI ON THE SAME DAY BEFORE FSI CLOSES FOR BUSINESS,  THE SHAREHOLDER  WILL
RECEIVE THE NET ASSET VALUE  CALCULATED ON THAT DAY REDUCED BY THE AMOUNT OF ANY
APPLICABLE CDSC AND THE AMOUNT OF ANY INCOME TAX REQUIRED TO BE WITHHELD.

D.  REDEMPTION  BY CHECK -- Only Class A and Class C shares may be  redeemed  by
check. A shareholder (except a $3 Million Shareholder) owning Class A or Class C
shares of the Fund may elect to have a special  account  with State  Street Bank
and Trust  Company (the "Bank") for the purpose of redeeming  Class A or Class C
shares from his or her account by check.  The Bank will  provide each Class A or
Class C shareholder,  upon request, with forms of checks drawn on the Bank. Only
shareholders  having  accounts in which no share  certificates  have been issued
will be permitted to redeem  shares by check.  Checks may be made payable in any
amount not less than $500.  Shareholders  wishing  to avail  themselves  of this
redemption by check  privilege  should so request on their Account  Application,
must  execute  signature  cards (for  additional  information,  see the  Account
Application) with signature guaranteed in the manner set forth under the caption
"Signature Guarantee", and must return any Class A or Class C share certificates
issued to them.  Additional  documentation  will be required from  corporations,
partnerships, fiduciaries or other such institutional investors. All checks must
be signed by the  shareholder(s)  of record exactly as the account is registered
before  the Bank  will  honor  them.  The  shareholders  of joint  accounts  may
authorize each shareholder to redeem by check. The check may not draw on monthly
dividends  which  have  been  declared  but not  distributed.  SHAREHOLDERS  WHO
PURCHASE  CLASS A SHARES  BY CHECK  (INCLUDING  CERTIFIED  CHECKS  OR  CASHIER'S
CHECKS) MAY WRITE CHECKS  AGAINST  THOSE SHARES ONLY AFTER THEY HAVE BEEN ON THE
FUND'S  BOOKS  FOR 15  DAYS.  WHEN  SUCH A CHECK  IS  PRESENTED  TO THE BANK FOR
PAYMENT,  A SUFFICIENT  NUMBER OF FULL AND FRACTIONAL SHARES WILL BE REDEEMED TO
COVER THE AMOUNT OF THE CHECK,  ANY APPLICABLE CDSC AND THE AMOUNT OF ANY INCOME
TAX REQUIRED TO BE WITHHELD. IF THE AMOUNT OF THE CHECK PLUS ANY APPLICABLE CDSC
AND THE AMOUNT OF ANY INCOME TAX  REQUIRED TO BE  WITHHELD  IS GREATER  THAN THE
VALUE OF THE CLASS A OR CLASS C SHARES HELD IN THE  SHAREHOLDER'S  ACCOUNT,  THE
CHECK  WILL BE  RETURNED  UNPAID,  AND THE  SHAREHOLDER  MAY BE SUBJECT TO EXTRA
CHARGES.  TO AVOID  DISHONOR  OF CHECKS DUE TO  FLUCTUATION  IN  ACCOUNT  VALUE,
SHAREHOLDERS  ARE  ADVISED  AGAINST  REDEEMING  ALL OR MOST OF THEIR  ACCOUNT BY
CHECK.  CHECKS SHOULD NOT BE USED TO CLOSE A FUND ACCOUNT BECAUSE WHEN THE CHECK
IS WRITTEN,  THE SHAREHOLDER  WILL NOT KNOW THE EXACT TOTAL VALUE OF THE ACCOUNT
ON THE DAY THE CHECK CLEARS. There is presently no charge to the shareholder for
the maintenance of this special account or for the clearance of any checks,  but
the Fund and the Bank  reserve the right to impose such  charges or to modify or
terminate the redemption by check privilege at any time.

SIGNATURE  GUARANTEE:  In order to  protect  shareholders  against  fraud to the
greatest extent  possible,  the Fund requires in certain  instances as indicated
above  that the  shareholder's  signature  be  guaranteed.  In these  cases  the
shareholder's  signature must be guaranteed by an eligible bank, broker, dealer,
credit union, national securities exchange,  registered securities  association,
clearing agency or savings  association.  Signature guarantees shall be accepted
in accordance with policies established by the Shareholder Servicing Agent.

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

Subject to the Fund's  compliance  with  applicable  regulations,  the Trust 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 transaction charges
when converting the securities to cash.

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

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

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

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

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  FSI a  distribution/service  fee  aggregating  up to  (but  not
necessarily all of) 0.35% of the average daily net assets  attributable to Class
A shares  annually  in order  that FSI may pay  expenses  on  behalf of the Fund
related to the distribution and servicing of Class A shares.  The expenses to be
paid by FSI on behalf of the Fund  include a service fee to  securities  dealers
which  enter  into a sales  agreement  with FSI of up to 0.25%  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.  FSI may from time to time  reduce the amount of the  service fee paid
for shares sold prior to a certain date. Currently, the service fee is 0.15% for
shares sold prior to March 1, 1991.  FSI 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 FSI's obligations  under its distribution  agreement with the
Fund. FSI,  however,  currently is waiving this 0.10%  distribution fee and will
not in the  future  accept  payment  of this fee  unless  it first  obtains  the
approval of the Board of Trustees. In addition, to the extent that the aggregate
of the  foregoing  fees does not exceed 0.35% per annum of the average daily net
assets of the Fund attributable to Class A shares,  the Fund is permitted to pay
other  distribution-related  expenses,  including  commissions  to  dealers  and
payments to  wholesalers  employed by FSI for sales at or above a certain dollar
level.  Fees  payable  under the Class A  Distribution  Plan are charged to, and
therefore  reduce,  income  applicable  to Class A shares.  Service  fees may be
reduced  for a  securities  dealer that is the holder or dealer of record for an
investor  who owns  shares of the Fund  having a net  asset  value at or above a
certain dollar level.  Dealers may from time to time be required to meet certain
criteria in order to receive service fees. FSI or its affiliates are entitled to
retain all service fees payable  under the Class A  Distribution  Plan for which
there is no dealer of record or for which qualification  standards have not been
met as partial  consideration for personal  services and/or account  maintenance
services  performed by FSI or its affiliates for shareholder  accounts.  Certain
banks and other financial institutions that have agency agreements with FSI will
receive service fees that are the same as service fees to dealers.

    CLASS B DISTRIBUTION  PLAN. The Class B Distribution  Plan provides that the
Fund will pay FSI a daily  distribution fee equal on an annual basis to 0.75% of
the Fund's average daily net assets  attributable to Class B shares and will pay
FSI a  service  fee of up to 0.25%  per annum of the  Fund's  average  daily net
assets  attributable to Class B shares (which FSI will in turn pay to securities
dealers which enter into a sales agreement with FSI at a rate of up to 0.25% per
annum of the Fund's  daily net assets  attributable  to Class B shares  owned by
investors  for whom that  securities  dealer is the holder or dealer of record).
This  service fee is intended to be  additional  consideration  for all personal
services and/or account maintenance services rendered by the dealer with respect
to Class B shares.  Fees payable under the Class B Distribution Plan are charged
to,  and  therefore  reduce,  income  allocated  to Class B shares.  The Class B
Distribution Plan also provides that FSI will receive all CDSCs  attributable to
Class B shares  (see  "Redemptions  and  Repurchases"),  which do not reduce the
distribution  fee. FSI will pay  commissions to dealers of 3.75% of the purchase
price of Class B shares  purchased  through  dealers.  FSI will also  advance to
dealers  the first year  service  fee at a rate  equal to 0.25% of the  purchase
price of such shares and, as compensation  therefor,  FSI may retain the service
fee paid by the Fund  with  respect  to such  shares  for the first  year  after
purchase.  Therefore,  the total amount paid to a dealer upon the sale of shares
is 4.00% of the purchase  price of the shares  (commission  rate of 3.75% plus 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  the  purchase.  Dealers  may from  time to time be
required to meet certain  criteria in order to receive  service fees. FSI or its
affiliates  are entitled to retain all service  fees  payable  under the Class B
Distribution  Plan with  respect  to  accounts  for which  there is no dealer of
record  or for  which  qualification  standards  have not  been  met as  partial
consideration  for  personal  services  and/or  account   maintenance   services
performed by FSI or its affiliates for shareholder accounts.  The purpose of the
distribution  payments  to  FSI  under  the  Class  B  Distribution  Plan  is to
compensate  FSI  for  its  distribution   services  to  the  Fund.  Since  FSI's
compensation  is not directly tied to its expenses,  the amount of  compensation
received  by FSI during  any year may be more or less than its actual  expenses.
For this reason,  this type of distribution  fee arrangement is characterized by
the staff of the SEC as being of the "compensation"  variety.  However, the Fund
is not  liable  for any  expenses  incurred  by FSI in excess  of the  amount of
compensation it receives. The expenses incurred by FSI, including commissions to
dealers,  are  likely  to be  greater  than the  distribution  fees for the next
several years,  but thereafter  such expenses may be less than the amount of the
distribution  fees.  Certain banks and other  financial  institutions  that have
agency agreements with FSI will receive agency transaction and service fees that
are the same as commissions and service fees to dealers.

    CLASS C DISTRIBUTION  PLAN. The Class C Distribution  Plan provides that the
Fund will pay FSI 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 FSI a
service  fee of up to 0.25% per annum of the  Fund's  average  daily net  assets
attributable  to Class C shares  (which FSI in turn pays to  securities  dealers
which enter into a sales  agreement  with FSI at a rate of up to 0.25% per annum
of the Fund's 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 FSI 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.  FSI 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 FSI or its  affiliates  for  shareholder  accounts.  The
purpose of the distribution  payments to FSI under the Class C Distribution Plan
is to compensate  FSI for its  distribution  services to the Fund.  Distribution
payments  under  the  Plan  will  be  used by FSI to pay  securities  dealers  a
distribution  fee in an amount  equal on an annual  basis to 0.75% of the Fund's
average daily net assets  attributable  to Class C shares owned by investors for
whom that securities dealer is the holder or dealer of record.  (Therefore,  the
total amount of distribution/service fees paid to a dealer on an annual basis is
1.00% of the  Fund's  average  daily net assets  attributable  to Class C shares
owned by  investors  for whom the  securities  dealer is the holder or dealer of
record.) FSI 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 FSl's  compensation  is not directly  tied to its
expenses, the amount of compensation received by FSI during any year may be more
or less than its actual expenses. For this reason, this type of distribution fee
arrangement  is  characterized  by  the  staff  of  the  SEC  as  being  of  the
"compensation"  variety.  However,  the  Fund is not  liable  for  any  expenses
incurred by FSI in excess of the amount of  compensation  it  receives.  Certain
banks and other financial institutions that have agency agreements with FSI 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 pay substantially all of the Fund's 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,  including  short-term  capital gains
from the sales of securities or other assets and premiums from options  written,
over a longer term, rather than its actual net investment income for the period.
The Fund may make one or more  distributions  during  the  calendar  year to its
shareholders  from any long-term  capital  gains,  and may also make one or more
distributions  during the  calendar  year to its  shareholders  from  short-term
capital  gains.  Shareholders  may elect to receive  dividends  and capital gain
distributions in either cash or additional shares of the same class with respect
to which a distribution is made. See "Tax Status" and  "Shareholder  Services --
Distribution  Options"  below.  Distributions  paid by the Fund with  respect to
Class A shares will generally be greater than those paid with respect to Class B
and Class C shares because  expenses  attributable to Class B and Class C shares
will generally be higher.

TAX STATUS
The Fund is treated as an entity separate from the other series of the Trust for
federal  income  tax  purposes.  In order to  minimize  the taxes the Fund would
otherwise  be  required  to pay,  the Fund  intends to  qualify 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 the  dividends  and capital gain  distributions  they
receive from the Fund,  whether paid in cash or in additional  shares.  The Fund
expects  that none of its  dividends or  distributions  will be eligible for the
dividends-received deduction for corporations.  Shareholders of the Fund may not
have to pay state and local taxes on  dividends  derived  from  interest on U.S.
Government obligations. Investors should consult with their tax advisers in this
regard.

A statement  setting  forth the federal  income tax status of all  dividends and
distributions for each calendar year,  including any portion taxable as ordinary
income, any portion taxable as long-term capital gains, the portion representing
interest on U.S. Government  obligations,  any portion  representing a return of
capital (which is free of current taxes but results in a basis  reduction),  and
the  amount,  if  any,  of  federal  income  tax  withheld  will be sent to each
shareholder promptly after the end of such year.

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

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

NET  ASSET  VALUE
The net asset value per share of each class of the Fund is  determined  each day
during which the Exchange is open for trading.  This  determination is made once
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.  Values of assets in the Fund's
portfolio are  determined  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 FSI prior to the close of that business day.

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

Each share of a class of the Fund represents an equal proportionate  interest in
the Fund with each other class,  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  nonassessable.  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,  assignments  and in certain other limited
circumstances.

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

PERFORMANCE INFORMATION
From time to time, the Fund will provide yield,  current  distribution  rate and
total rate of return quotations for each class of shares and may also quote fund
rankings in the relevant fund category from various sources,  such as the Lipper
Analytical Services,  Inc. and Wiesenberger  Investment Companies Service. Yield
quotations are based on the annualized net investment income per share allocated
to each  class of the Fund  over a 30-day  period  stated  as a  percent  of the
maximum  public  offering  price of that  class on the last day of that  period.
Yield  calculations  for  Class B shares  assume  no CDSC is paid.  The  current
distribution  rate for each class is  generally  based upon the total  amount of
dividends  per share paid by the Fund to  shareholders  of that class during the
past 12 months and is computed by dividing  the amount of such  dividends by the
maximum public  offering price of that class at the end of such period.  Current
distribution  rate  calculations  for Class B shares assume no CDSC is paid. The
current  distribution  rate  differs from the yield  calculation  because it may
include  distributions  to  shareholders  from sources other than  dividends and
interest, such as premium income from option writing,  short-term capital gains,
and return of invested  capital,  and is calculated  over a different  period of
time. Total rate of return quotations will reflect the average annual percentage
change over stated periods in the value of an investment in each class of shares
of the Fund made at the  maximum  public  offering  price of the  shares of that
class with all distributions  reinvested and which, if quoted for periods of six
years or less,  will give effect to the  imposition  of the CDSC  assessed  upon
redemptions of the Fund's Class B shares.  Such total rate of return  quotations
may be accompanied by quotations  which do not reflect the reduction in value of
the initial investment due to the sales charge or the deduction of the CDSC, and
which will thus be higher.  All  performance  quotations are based on historical
performance and are not intended to indicate future performance.  Yield reflects
only net portfolio income as of a stated period of time and current distribution
rate  reflects  only the rate of  distributions  paid by the Fund  over a stated
period of time, while total rate of return reflects all components of investment
return over a stated period of time. The Fund's quotations may from time to time
be used in  advertisements,  shareholder  reports  or  other  communications  to
shareholders.  For a discussion  of the manner in which the Fund will  calculate
its yield, current distribution rate and total rate of return, see the Statement
of Additional  Information.  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.
Cancelled  checks, if any, will be sent to shareholders  monthly.  At the end of
each  calendar  year,  each  shareholder  will  receive  income tax  information
regarding reportable dividends and capital gain distributions for that year (see
"Tax Status").

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

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

     -- Dividends in cash; capital gain  distributions  reinvested in additional
        shares;

     -- Dividends and capital gain distributions in cash.

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

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

    LETTER  OF  INTENT:  If a  shareholder  (other  than a  group  purchaser  as
described in the Statement of  Additional  Information)  anticipates  purchasing
$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 (a bank collective  investment  fund) within a 13-month period
(or 36-month  period for purchases of $1 million or more),  the  shareholder may
obtain such shares of the Fund at the same  reduced  sales  charge as though the
total quantity were invested in one lump sum,  subject to escrow  agreements and
the  appointment  of an attorney for  redemptions  from the escrow amount if the
intended purchases are not completed, by completing the Letter of Intent section
of the Account Application.

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

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

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

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

    AUTOMATIC  EXCHANGE PLAN:  Shareholders  having account balances of at least
$5,000 in any MFS Fund may exchange their shares for the same class of shares of
other MFS Funds (and in the case of Class C shares,  for shares of the MFS Money
Market Fund) under the Automatic  Exchange  Plan.  The  Automatic  Exchange Plan
provides  for  automatic  monthly  or  quarterly  transfers  of  funds  from the
shareholder's  account in an MFS Fund for investment in the same class of shares
of other MFS Funds  selected by the  shareholder.  Under the Automatic  Exchange
Plan,  transfers of at least $50 each may be made to up to four different funds.
A shareholder  should  consider the  differences in objectives and policies of a
fund and review its prospectus  before electing to transfer money into such fund
through the Automatic Exchange Plan. No transaction fee is imposed in connection
with transfer transactions under the Automatic Exchange Plan. However, transfers
of shares of MFS Money Market Fund, MFS Government Money Market Fund 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 shares transferred and,  therefore,  could result in a capital gain or
loss to the  shareholder  making the  transfer.  See the Statement of Additional
Information  for further  information  concerning  the Automatic  Exchange Plan.
Investors  should  consult  their tax advisers  for  information  regarding  the
potential capital gain and loss consequences of transactions under the Automatic
Exchange Plan.

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

TAX-DEFERRED RETIREMENT PLANS -- Except as noted under "Purchases -- Class C
Shares," shares of the Fund may be purchased by all types of tax-deferred
retirement plans, including IRAs, SEP-IRA plans, 401(k) plans, 403(b) plans
and other corporate pension and profit-sharing plans. Investors should consult
with their tax adviser before establishing any of these tax-deferred
retirement plans.

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

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

AA: Debt rated AA has a 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
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.

The chart above indicates the composition of the Fund's portfolio for the fiscal
year ended April 30, 1994, with the debt securities  rated by S&P separated into
the  indicated  categories.  The  percentages  were  calculated by averaging the
monthly  dollar  weighted  average of the Fund's  net  assets  invested  in each
category.  The chart does not  necessarily  indicate what the composition of the
Fund's  portfolio  will  be in  subsequent  fiscal  years.  Rather,  the  Fund's
investment objective, policies and restrictions indicate the extent to which the
Fund may purchase securities in the various categories.
