 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
   AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE

Each Fund's  investment  adviser and  distributor  are  Massachusetts  Financial
Services  Company  (the  "Adviser"  or "MFS")  and MFS Fund  Distributors,  Inc.
("MFD"), respectively, both of which are located at 500 Boylston Street, Boston,
Massachusetts 02116. Each Fund is a series of MFS Series Trust I (the "Trust").

The Special  Opportunities  Fund and the  Convertible  Securities  Fund each may
invest up to 100% of its net  assets in lower  rated  bonds,  commonly  known as
"junk  bonds,"  that  entail  greater  risks  than those  found in higher  rated
securities.  Investors  should  carefully  consider these risks before investing
(see "Additional Risk Factors - Lower Rated Bonds").

While three classes of shares of each Fund are described in this Prospectus, the
Funds do not  currently  offer  Class B and Class C Shares.  Class A shares  are
available  for  purchase  at net asset  value only by  employees  of MFS and its
affiliates  and  certain  of  their  family  members  who are  residents  of The
Commonwealth  of  Massachusetts,  and  members  of the  governing  boards of the
various funds sponsored by MFS.

   
This Prospectus  sets forth  concisely the information  concerning each Fund and
the Trust that a prospective investor ought to know before investing. The Trust,
on behalf of each Fund, has filed with the  Securities  and Exchange  Commission
(the "SEC") a Statement of  Additional  Information,  dated March 17,  1998,  as
amended or  supplemented  from time to time (the  "SAI"),  which  contains  more
detailed  information  about the Trust and each Fund.  See page 40 for a further
description  of the  information  set forth in the SAI. A copy of the SAI may be
obtained without charge by contacting the Shareholder  Servicing Agent (see back
cover for address and phone number).  The SAI is  incorporated by reference into
this   Prospectus.   The  SEC   maintains  an  Internet   World  Wide  Web  site
(http://www.sec.gov)  that contains the SAI,  materials that are incorporated by
reference  into this  Prospectus  and SAI, and other  information  regarding the
Funds.

(1)      Purchases  of $1 million or more and certain  purchases  by  retirement
         plans are not subject to an initial sales charge; however, a contingent
         deferred sales charge  ("CDSC") of 1% will be imposed on such purchases
         in the  event of  certain  redemption  transactions  within  12  months
         following  such purchases (see  "Information  Concerning  Shares of the
         Funds - Purchases").

   
(2)      The Adviser  intends during the Funds' current fiscal year to waive its
         right to receive  management  fees from each Fund.  Absent this waiver,
         "Management Fees" would be as follows:

   Core       Special      Convertible      Blue    Science and       Real
  Growth   Opportunities   Securities       Chip     Technology      Estate

(3)      Each  Fund  has  adopted  a   distribution   plan  for  its  shares  in
         accordance  with Rule 12b-1 under the  Investment  Company Act of 1940,
         as amended (the "1940 Act") (the "Distribution  Plan"),  which provides
         that it will pay  distribution/service  fees aggregating up to (but not
         necessarily  all of) 0.50% per annum of the  average  daily net  assets
         attributable  to Class A shares of the Core  Growth  Fund,  the Special
         Opportunities  Fund,  the  Convertible  Securities  Fund, the Blue Chip
         Fund and the  Science  and  Technology  Fund and 0.35% per annum of the
         average  daily net  assets  attributable  to Class A shares of the Real
         Estate  Fund.   Distribution   and  service  fees  under  the  Class  A
         Distribution  Plan are  currently  being  waived on a  voluntary  basis
         and,  while they may be imposed at the  discretion  of MFD at any time,
         MFD  currently  intends to waive these fees  during the Funds'  current
         fiscal  year.  Distribution  expenses  paid  under the  Plan,  together
         with the initial  sales charge,  may cause  long-term  shareholders  to
         pay  more  than  the  maximum   sales   charge  that  would  have  been
         permissible  if  imposed  entirely  as an  initial  sales  charge.  See
         "Information  Concerning  Shares  of the  Funds  -  Distribution  Plan"
         below.
    

(4)      Each   Fund's   Distribution   Plan   provides   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
         Class  B  shares  and  Class  C  shares,   respectively.   Distribution
         expenses  paid under the  Distribution  Plan with respect to Class B or
         Class C shares,  together  with any CDSC  payable  upon  redemption  of
         Class B and Class C shares,  may cause  long-term  shareholders  to pay
         more than the maximum  sales  charge  that would have been  permissible
         if  imposed  entirely  as an initial  sales  charge.  See  "Information
         Concerning Shares of the Funds - Distribution Plan" below.

   
(5)      The  Adviser has agreed to bear the  expenses of the Core Growth  Fund,
         the  Convertible  Securities  Fund, the Blue Chip Fund, the Science and
         Technology Fund and the Real Estate Fund,  subject to  reimbursement by
         each Fund,  such that  "Other  Expenses"  do not  exceed  1.50% for the
         Core Growth Fund,  Convertible  Securities Fund, the Blue Chip Fund and
         the Science  and  Technology  Fund and 1.65% for the Real Estate  Fund,
         per annum,  of each such  Fund's  average  daily net assets  during the
         current fiscal year.  See  "Information  Concerning  Shares of the Fund

(7)      Each Fund has an expense  offset  arrangement  which reduces the Fund's
         custodian fee based upon the amount of cash maintained by the Fund with
         its custodian and dividend  disbursing  agent, and may enter into other
         such arrangements and directed brokerage arrangements (which would also
         have  the  effect  of  reducing  the  Fund's  expenses).  Any  such fee
         reductions are not reflected under "Other Expenses."

3.       THE FUNDS

   
Each Fund is a series of the Trust, an open-end  management  investment  company
which was organized as a business  trust under the laws of The  Commonwealth  of
Massachusetts  on July 30, 1986. Each Fund is a diversified  fund except for the
Special  Opportunities Fund and the Real Estate Fund, which are non-diversified.
The Trust presently consists of fourteen series,  eight of which are offered for
sale pursuant to separate prospectuses, and each of which represents a portfolio
with separate investment  objectives and policies.  Shares of each Fund are sold
continuously  to the  public  and  each  Fund  then  uses  the  proceeds  to buy
securities  for its  portfolio.  While  each  Fund has three  classes  of shares
designed  for sale  generally  to the public,  Class A shares are the only class
presently available for sale. Class A shares are offered at net asset value plus
an  initial  sales  charge up to a maximum of 4.75%  (5.75% for the Real  Estate
Fund) of the offering price (or a CDSC of 1.00% upon redemption during the first
year in the  case of  certain  purchases  of $1  million  or  more  and  certain
purchases by retirement plans) and are subject to an annual distribution fee and
service fee up to a maximum of 0.50% (0.35% for the Real Estate Fund) per annum.
Class B shares are offered at net asset value  without an initial  sales  charge
but are subject to a CDSC upon redemption (declining from 4.00% during the first
year to 0% after six years) and an annual distribution fee and service fee up to
a maximum  of 1.00% per  annum;  Class B shares  will  convert to Class A shares
approximately  eight  years  after  purchase.  Class C shares are offered at net
asset value  without an initial  sales charge but are subject to a CDSC of 1.00%
upon redemption during the first year and an annual distribution fee and service
fee up to a maximum  of 1.00% per  annum.  Class C shares do not  convert to any
other class of shares of a Fund.  In  addition,  the Funds  offer an  additional
class of shares, Class I shares, exclusively to certain institutional investors.
Class I shares are made available by means of a separate  Prospectus  supplement
provided to institutional  investors eligible to purchase Class I shares and are
offered  at net  asset  value  without  an  initial  sales  charge  or CDSC upon
redemption and without an annual distribution and service fee.
    

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

4.       INVESTMENT OBJECTIVES AND POLICIES

Each  Fund  has an  investment  objective  which  it  pursues  through  separate
investment  policies,  as described  below.  The  differences  in objectives and
policies among the Funds can be expected to affect the market and financial risk
to which each Fund is subject and the  performance  of each Fund. The investment
objective and polices of each Fund, unless otherwise specifically stated, may be
changed  by the  Trustees  of the Trust  without a vote of the  shareholders.  A
change  in a Fund's  objective  may  result  in the Fund  having  an  investment
objective different from the objective which shareholders considered appropriate
at the time of investment in the Fund. Any investment involves risk and there is
no assurance that the investment objective of any Fund will be achieved.

CORE  GROWTH  FUND - The Core  Growth  Fund's  investment  objective  is capital
appreciation.

Under  normal  market  conditions,  the Fund  invests  at least 65% of its total
assets in equity  securities of well-known and  established  companies which the
Adviser believes have  above-average  growth potential (see "Certain  Securities
and Investment  Techniques - Equity Securities" below). When choosing the Fund's
investments,  the  Adviser  seeks  companies  that it expects  will  demonstrate
greater  long-term  earnings growth than the average company included in the S&P
500.  This  method of stock  selection  is based on the belief  that growth in a
company's  earnings will  eventually  translate  into growth in the price of its
stock.  The  Fund  may also  invest  up to 35% of its  total  assets  in  equity
securities of companies in the developing  stages of their life cycle that offer
the  potential  for  accelerated  earnings or revenue  growth  (emerging  growth
companies).  Such companies  generally would be expected to show earnings growth
over time that is well above the growth rate of the overall economy and the rate
of inflation,  and would have the products,  management and market opportunities
which  are  usually  necessary  to  become  more  widely  recognized  as  growth
companies.

Consistent with its investment  objective and policies described above, the Fund
may  invest  up to 35% (and  generally  expects  to invest up to 20%) of its net
assets in foreign equity securities which are not traded on an U.S.
exchange.

The Fund may engage in certain  investment  techniques  as  described  under the
caption "Certain Securities and Investment Techniques" below and in the SAI. The
Fund's   investments   are  subject  to  certain  risks,  as  described  in  the
above-referenced  sections of this Prospectus and the SAI and as described below
under the caption "Additional Risk Factors."

                                        -11-
<PAGE>

SPECIAL  OPPORTUNITIES  FUND  -  The  Special  Opportunities  Fund's  investment
objective is capital appreciation.

Under normal market conditions, the Fund invests substantially all of its assets
in equity and fixed  income  securities  which the  Adviser  believes  represent
uncommon value by having the potential for significant capital appreciation over
a period  of 12  months  or  longer  (see  "Certain  Securities  and  Investment
Techniques  - Equity  Securities"  below).  The issuers of such  securities  may
include companies out-of-favor in the marketplace or in out-of-favor industries,
companies  currently  performing  well but in  industries  where the  outlook is
questionable and over-leveraged  companies with promising longer-term prospects.
Some of these companies may be experiencing financial or operating difficulties,
and certain of these  companies may be involved,  at the time of  acquisition or
soon  thereafter,  in  reorganizations,  capital  restructurings  or  bankruptcy
proceedings;  however,  most of these  companies will not be  experiencing  such
financial or operating  difficulties as will lead, in the Adviser's opinion,  to
reorganizations,  capital restructurings or bankruptcy proceedings.  The Adviser
will determine the relative  apportionment of the Fund's assets among particular
equity and fixed income investments based on their appreciation  potential.  The
Fund may invest a substantial amount of its assets in U.S. Government Securities
when,  in the  judgment  of the  Adviser,  securities  with  the  potential  for
significant capital appreciation are not available for purchase by the Fund (see
"Certain  Securities and  Investment  Techniques - U.S.  Government  Securities"
below).

The Fund may invest in companies of any size,  including  smaller,  lesser known
companies in the developing  stages of their life cycle that offer the potential
for accelerated  earnings or revenue growth  (emerging growth  companies).  Such
companies  generally would be expected to show earnings growth over time that is
well above the growth rate of the overall economy and the rate of inflation, and
would have the products,  management and market  opportunities which are usually
necessary to become more widely recognized as growth companies.

   
The fixed income  securities  in which the Fund may invest  include fixed income
securities  rated BB or lower by  Standard & Poor's  Ratings  Services  ("S&P"),
Fitch IBCA, Inc.  ("Fitch") or Duff & Phelps Credit Rating Co. ("Duff & Phelps")
or Ba or lower by Moody's Investors Service,  Inc.  ("Moody's"),  or if unrated,
determined to be of equivalent  quality by the Adviser (commonly  referred to as
"junk  bonds").  For a  description  of these  ratings,  see  Appendix B to this
Prospectus.  Up to  100%  of the  Fund's  net  assets  may be  invested  in such
lower-rated  fixed income securities (see "Additional Risk Factors - Lower Rated
Bonds" below).
    

The Fund may engage in short sales of  securities  which the Adviser  expects to
decline in price (see  "Certain  Securities  and  Investment  Techniques - Short
Sales" below).  The Fund may also borrow from banks and use the proceeds of such
borrowings to invest in portfolio  securities,  thereby  creating  leverage (see
"Investment Techniques - Borrowing and Leverage" below).

Consistent with its investment  objective and policies described above, the Fund
may  invest  up to 50% of its net  assets in  foreign  equity  and  fixed-income
securities which are not traded on an U.S. exchange.

The Fund may engage in certain  investment  techniques  as  described  under the
caption "Certain Securities and Investment Techniques" below and in the SAI. The
Fund's   investments   are  subject  to  certain  risks,  as  described  in  the
above-referenced  sections of this Prospectus and the SAI and as described below
under the caption "Additional Risk Factors."

CONVERTIBLE  SECURITIES  FUND - The  Convertible  Securities  Fund's  investment
objective is to maximize  total return  through a combination  of current income
and capital appreciation.

         The Fund seeks to achieve its  objective  by  investing,  under  normal
market conditions, at least 65% of its total assets in convertible securities. A
convertible  security is generally a debt obligation or preferred stock that may
be converted  within a specified  period of time into a certain amount of common
stock of the same or a different issuer. A convertible security provides a fixed
income  stream  and  the  opportunity,   through  its  conversion   feature,  to
participate in the capital appreciation resulting from a market price advance in
its  underlying  common  stock.  As with a straight  fixed  income  security,  a
convertible  security  tends to increase  in market  value when  interest  rates
decline and decrease in value when interest rates rise. Like a common stock, the
value of a  convertible  security  also tends to increase as the market value of
the underlying stock rises and to decrease as the market value of the underlying
stock  declines.  Because its value can be  influenced by both interest rate and
market movements,  a convertible  security is not as sensitive to interest rates
as a similar fixed income  security,  nor is it as sensitive to changes in share
price as its underlying stock.

   
         The  remaining  35% of the  Fund's  total  assets  may be  invested  in
non-convertible  corporate and U.S.  Government fixed income securities,  equity
securities and money market  instruments.  The Fund's policies permit investment
in convertible and non-convertible  fixed income securities without restrictions
as to maturity or duration.  The  convertible and  non-convertible  fixed income
securities in which the Fund may invest include fixed income securities rated BB
or lower  by S&P,  Fitch or Duff &  Phelps  or Ba or  
    

                                        -12-

lower by Moody's,  or if unrated,  determined to be of equivalent quality by the
Adviser  (commonly  referred to as "junk  bonds").  For a  description  of these
ratings, see Appendix B to this Prospectus.  Up to 100% of the Fund's net assets
may be invested in such lower rated fixed  income  securities  (see  "Additional
Risk Factors - Lower Rated Bonds" below).

         The Fund may  engage in short  sales of  securities  which the  Adviser
expects to decline in price (see "Certain Securities and Investment Techniques -
Short Sales" below).

         Consistent with its investment  objective and policies described above,
the Fund may invest up to 20% (and generally  expects to invest up to 5%) of its
net assets in foreign securities which are not traded on an U.S.
exchange.

         The Fund may engage in certain investment techniques as described under
the caption "Certain Securities and Investment Techniques" below and in the SAI.
The Fund's  investments  are  subject  to certain  risks,  as  described  in the
above-referenced  sections of this Prospectus and the SAI and as described below
under the caption "Additional Risk Factors."

BLUE  CHIP  FUND  -  The  Blue  Chip  Fund's  investment  objective  is  capital
appreciation.

         The Fund seeks to achieve its  objective  by  investing,  under  normal
market  conditions,  at least 65% of its total  assets in equity  securities  of
well-known,  stable and established  companies  which the Adviser  believes have
above  average  capital  appreciation  potential,  commonly  known as "Blue Chip
Companies."  Blue Chip  Companies are those  companies  generally  identified by
having a market capitalization of at least $1 billion unless the company's stock
is included in the S&P 500 or the Dow Jones  Industrial  Average or is traded on
the New York Stock Exchange, established history of earnings and dividends, easy
access to credit,  good  industry  position and superior  management  structure.
These companies also typically have a large number of publicly held shares and a
high trading  volume,  resulting in a high degree of  liquidity.  While the Fund
will primarily invest in equity securities of such companies, it may also invest
in other equity and fixed income securities  offering an opportunity for capital
appreciation,  such as companies in a relatively early stage of development that
offer the potential for accelerated  earnings or revenue growth (emerging growth
companies).

         Consistent with its investment  objective and policies described above,
the Fund may also invest any portion or all (and generally  expects to invest up
to 50%) of its net assets in foreign  securities which are not traded on an U.S.
exchange.

         The Fund may engage in certain investment techniques as described under
the caption "Certain Securities and Investment Techniques" below and in the SAI.
The Fund's  investments  are  subject  to certain  risks,  as  described  in the
above-referenced  sections of this Prospectus and the SAI and as described below
under the caption "Additional Risk Factors."

SCIENCE  AND  TECHNOLOGY  FUND - The Science and  Technology  Fund's  investment
objective is capital appreciation.

         The Fund seeks to achieve its  objective  by  investing,  under  normal
market  conditions,  at least 65% of its total  assets in equity  securities  of
companies   which  the  Adviser   believes  will  benefit  from  scientific  and
technological  advances and improvements.  These companies may include companies
in many different fields, such as, for example,  computer software and hardware,
semiconductor,  minicomputers and peripheral equipment,  scientific instruments,
telecommunications,   pharmaceuticals,  environmental  services,  chemicals  and
synthetic  materials,  defense  and  commercial  electronics,  data  storage and
retrieval, biotechnology, health care and medical supplies, among others.

         The Fund may invest in companies of any size, including smaller, lesser
known  companies  in the  developing  stages of their  life cycle that offer the
potential  for  accelerated   earnings  or  revenue  growth   (emerging   growth
companies).  Such companies  generally would be expected to show earnings growth
over time that is well above the growth rate of the overall economy and the rate
of inflation,  and would have the products,  management and market opportunities
which  are  usually  necessary  to  become  more  widely  recognized  as  growth
companies.

         The Fund may  engage in short  sales of  securities  which the  Adviser
expects to decline in price (see "Certain Securities and Investment Techniques -
Short Sales" below).

   
         While the Fund generally will invest in equity securities,  it may also
invest  in  fixed  income   securities   offering  an  opportunity  for  capital
appreciation,  including up to 30% of its net assets in fixed income  securities
rated BB or lower by S&P, Fitch and Duff & Phelps or Ba and lower by Moody's, or
if unrated,  determined  to be of  equivalent  quality by the Adviser  (commonly
referred to as "junk bonds"). For a description of these ratings, see Appendix B
to this Prospectus (see "Additional Risk Factors - Lower Rated Bonds" below).

         Consistent with its investment  objective and policies described above,
the Fund may invest up to 50% (and generally expects to invest up to 20%) of its

an U.S. exchange.

         The Fund may engage in certain investment techniques as described under

The Fund's  investments  are  subject  to certain  risks,  as  described  in the

REAL  ESTATE  FUND - The Real  Estate  Fund's  investment  objective  is capital
appreciation and income.

         Under normal  market  conditions,  the Fund invests at least 65% of its
total assets in equity securities of companies  principally  engaged in the real
estate  industry  (see "Certain  Securities  and  Investment  Techniques--Equity
Securities"  below). A company will be considered to be "principally  engaged in
the real estate  industry"  if, in the opinion of the  Adviser,  at the time its
securities  are  purchased by the Fund, at least 50% of its revenues or at least
50% of the  market  value  of  its  assets  is  attributable  to the  ownership,
construction,  financing,  management  or sale  of  residential,  commercial  or
industrial  real  estate.  Companies  principally  engaged  in the  real  estate
industry  may  include,  among  others,  equity  real estate  investment  trusts
("REITs") and real estate master limited  partnerships,  mortgage REITs and real
estate brokers and developers.

         REITs  pool  investors'  funds  for  investment   primarily  in  income
producing real estate or real estate  related loans or interests.  A REIT is not
taxed  on  income  distributed  to  shareholders  if it  complies  with  various
requirements relating to its organization, ownership, assets and income and with
the  requirement  that it  distribute  to its  shareholders  at least 95% of its
taxable income (other than net capital  gains) for each taxable year.  REITs can
generally be classified as equity REITs, mortgage REITs and hybrid REITs. Equity
REITs invest the majority of their assets  directly in real  property and derive
their income  primarily from rents.  Equity REITs can also realize capital gains
by selling  property that has  appreciated  in value.  Mortgage REITs invest the
majority  of their  assets in real  estate  mortgages  and derive  their  income
primarily from interest  payments.  Hybrid REITs combine the  characteristics of
both equity REITs and mortgage REITs.

         The  Fund's  policy  to  concentrate   its   investments  in  companies
principally involved in the real estate industry entails certain risks described
under the caption "Additional Risk Factors."

         The  remaining  35% of the Fund's  total  assets may be invested in all
types of domestic and foreign equity and fixed income  securities.  The Fund may
invest up to 20% of its net assets in fixed income  securities rated BB or lower
by S&P,  Fitch  or Duff &  Phelps  or Ba or lower  by  Moody's,  or if  unrated,
determined to be of equivalent  quality by the Adviser (commonly  referred to as
"junk  bonds").  For a  description  of these  ratings,  see  Appendix  B to the
Prospectus.

         The Fund may  engage in short  sales of  securities  which the  Adviser
expects  to  decline  in  price  (see   "Certain   Securities   and   Investment
Techniques--Short Sales" below.)

         Consistent with its investment  objective and policies described above,
the Fund may  invest up to 20% of its net  assets in  foreign  equity  and fixed
income securities which are not traded on an U.S. exchange.

         The Fund may engage in certain investment techniques as described under
the caption "Certain Securities and Investment Techniques" below and in the SAI.
The Fund's  investments  are  subject  to certain  risks,  as  described  in the
above-referenced  sections of this Prospectus and the SAI and as described below

<PAGE>

receipts for those  securities.  These  securities  may be listed on  securities
exchanges,  traded in  various  over-the-counter  markets  or have no  organized
market.

         Fixed Income Securities: Fixed income securities in which each Fund may
invest include bonds, debentures,  mortgage securities, notes, bills, commercial
paper, U.S.  Government  Securities and certificates of deposit, as well as debt
obligations  which  may have a call on  common  stock  by means of a  conversion
privilege or attached warrants.

   
         Restricted  Securities:  Each Fund may purchase securities that are not
registered  under the  Securities  Act of 1933  (the  "1933  Act")  ("restricted
securities"),  including  those  that  can be  offered  and  sold to  "qualified
institutional   buyers"   under  Rule  144A  under  the  1933  Act  ("Rule  144A
securities").  A  determination  is made based upon a  continuing  review of the
trading  markets for a specific  Rule 144A  security,  whether such  security is
liquid and thus not subject to a Fund's  limitation  on investing  not more than
15% of its net assets in illiquid investments. The Board of Trustees has adopted
guidelines and delegated to the Adviser the daily  function of  determining  and
monitoring the liquidity of Rule 144A securities.  The Board,  however,  retains
sufficient oversight of the liquidity  determinations,  focusing on factors such
as valuation, liquidity and availability of information.  Investing in Rule 144A
securities  could have the effect of decreasing the level of liquidity in a Fund
to the extent that qualified institutional buyers become for a time uninterested
in purchasing Rule 144A securities held in the Fund's portfolio. Subject to each
Fund's 15% limitation on investments  in illiquid  investments,  a Fund may also
invest in  restricted  securities  that may not be sold under  Rule 144A,  which
presents  certain  risks.  As a result,  a 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.
    

         Lending of  Portfolio  Securities:  Each Fund may seek to increase  its
income by lending  portfolio  securities.  Such  loans  will  usually be made to
member  firms (and  subsidiaries  thereof) of the New York Stock  Exchange  (the
"Exchange")  and to member  banks of the Federal  Reserve  System,  and would be
required to be secured  continuously by collateral in cash,  irrevocable letters
of credit or U.S. Treasury securities maintained on a current basis at an amount
at least  equal to the market  value of the  securities  loaned.  If the Adviser
determines to lend  portfolio  securities,  it is intended that the value of the
securities  loaned  would not  exceed  30% of the value of the net assets of the
Fund making the loans.

         Repurchase  Agreements:  Each Fund may enter into repurchase agreements
in order to earn income on available cash or as a temporary  defensive  measure.
Under a repurchase agreement, a 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).  Each
Fund has adopted  certain  procedures  intended  to  minimize  the risks of such
transactions.

         "When  Issued"  Securities:  Each  Fund may  purchase  securities  on a
"when-issued" or on a "forward  delivery" basis, which means that the securities
will be delivered to a 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, a 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,  a Fund  will  segregate  liquid  assets
sufficient to cover its  commitments.  Although the Fund does not intend to make
such purchases for speculative  purposes,  purchases of securities on such bases
may involve more risk than other types of purchases.

         U.S.  Government  Securities:  The Special  Opportunities  Fund and the
Convertible  Securities  Fund generally may invest,  and each Fund for temporary
defensive  purposes,   as  discussed  below,  may  invest,  in  U.S.  Government
securities, including: (1) U.S. Treasury obligations, which differ only in their
interest  rates,   maturities  and  times  of  issuance:   U.S.  Treasury  bills
(maturities of one year or less);  U.S. Treasury notes (maturities of one to ten
years);  and U.S.  Treasury  bonds  (generally  maturities  of greater  than ten
years),  all of which  are  backed  by the full  faith  and  credit  of the U.S.
Government;  and  (2)  obligations  issued  or  guaranteed  by  U.S.  Government
agencies, authorities or instrumentalities, some of which are backed by the full
faith and credit of the U.S. Treasury, e.g., direct pass-through certificates of
the  Government  National  Mortgage  Association  ("GNMA");  some of  which  are
supported by the right of the issuer to borrow from the U.S.  Government,  e.g.,
obligations of Federal Home Loan Banks; and some of which are backed only by the
credit of the issuer  itself,  e.g.,  obligations  of the Student Loan Marketing
Association  (collectively,   "U.S.  Government  Securities").  The  term  "U.S.
Government  Securities"  also  includes  interests  in trusts or other  entities
issuing interests in obligations that are backed by the full faith and credit of
the U.S.  Government  or are issued or guaranteed  by the U.S.  Government,  its
agencies, authorities or instrumentalities.

         Investments for Temporary Defensive Purposes: During periods of unusual
market  conditions  when the  Adviser  believes  that  investing  for  temporary
defensive  purposes is appropriate,  or in order to meet anticipated  redemption
requests, a large portion or 

                                        -15-
<PAGE>
all of the assets of a Fund may be invested in cash (including foreign currency)
or cash  equivalents,  including,  but not  limited  to,  obligations  of  banks
(including  certificates  of deposit,  bankers'  acceptances,  time deposits and
repurchase  agreements),  commercial paper,  short-term  notes, U.S.  Government
Securities and related repurchase agreements.

   
         Emerging Growth Companies:  Each Fund may invest in securities of small
and  medium-size  U.S. and foreign  companies that are early in their life cycle
but which  have the  potential  to become  major  enterprises  (emerging  growth
companies).  Such  companies  may be of any  size,  would  be  expected  to show
earnings  growth  over time that is well  above the growth  rate of the  overall
economy and the rate of inflation, and would have the products,  management, and
market   opportunities  which  are  usually  necessary  to  become  more  widely
recognized  as growth  companies.  A Fund may also  invest  in more  established
companies whose rates of earnings  growth are expected to accelerate  because of
special  factors,  such as  rejuvenated  management,  new  products,  changes in
consumer demand, or basic changes in the economic environment or which otherwise
represent  opportunities  for  long-term  growth.  See "Risk  Factors - Emerging
Growth  Companies"  below.  A Fund  may  also  invest  to a  limited  extent  in
restricted  securities of companies which the Adviser  believes have significant
growth potential.  These securities may be considered speculative and may not be
readily marketable. See "Restricted Securities."
    

         Foreign  Growth  Securities:  Each  Fund may  invest in  securities  of
foreign growth companies,  including established foreign companies,  whose rates
of earnings growth are expected to accelerate  because of special factors,  such
as rejuvenated  management,  new products,  changes in consumer demand, or basic
changes in the economic  environment or which otherwise represent  opportunities
for long-term growth. See "Additional Risk Factors - Foreign  Securities" below.
It is  anticipated  that these  companies will primarily be in nations with more
developed  securities markets,  such as Japan,  Australia,  Canada, New Zealand,
Hong Kong and most Western European countries, including Great Britain.

         Emerging  Markets  Securities:  Consistent with each Fund's  respective
objectives  and  policies,  each Fund may invest in  securities of issuers whose
principal activities are located in emerging market countries (which may include
foreign  governments  and their  subdivisions,  agencies or  instrumentalities).
Emerging  markets  include  any  country  determined  by the  Adviser to have an
emerging  market  economy,  taking into  account a number of factors,  including
whether  the  country  has a low-  to  middle-income  economy  according  to the
International  Bank for  Reconstruction  and Development,  the country's foreign
currency debt rating,  its political and economic  stability and the development
of its financial and capital markets. The Adviser determines whether an issuer's
principal  activities  are located in an emerging  market country by considering
such factors as its country of  organization,  the principal  trading market for
its  securities  and the source of its revenues and location of its assets.  The
issuer's principal activities generally are deemed to be located in a particular
country if: (a) the security is issued or guaranteed  by the  government of that
country or any of its agencies, authorities or instrumentalities; (b) the issuer
is  organized  under the laws of, and  maintains  a  principal  office in,  that
country;  (c) the issuer has its  principal  securities  trading  market in that
country;  (d) the issuer  derives 50% or more of its total  revenues  from goods
sold or services performed in that country; or (e) the issuer has 50% or more of
its assets in that  country.  See  "Additional  Risk  Factors - Emerging  Market
Securities" below.

         Indexed  Securities:  Each 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 (i.e.,  principal value)
and/or  interest  rates rise or fall according to changes in the value of one or
more specified underlying  instruments.  Indexed securities may be positively or
negatively  indexed (i.e.,  their principal value or interest rates 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 and could involve the loss of all
or a portion of or interest on the principal amount of the investment.

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

         Each 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

                                        -16-
<PAGE>

obligates  the seller to make  payments to the extent that a specified  interest
rate falls below an agreed-upon level. A collar arrangement combines elements of
buying a cap and selling a floor.

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

   
         Swap agreements are  sophisticated  hedging  instruments that typically
involve a small investment of cash relative to the magnitude of risk assumed, or
no investment of cash. As a result,  swaps can be highly volatile and may have a
considerable  impact on a Fund's  performance.  Swap  agreements  are subject to
risks related to the counterparty's ability to perform, and may decline in value
if the  counterparty's  creditworthiness  deteriorates.  A Fund may also  suffer
losses if it is unable to terminate  outstanding  swap  agreements or reduce its
exposure through  offsetting  transactions.  Swaps, caps, floors and collars are
highly  specialized  activities  which involve certain risks as described in the
SAI.
    

         Options on Securities:  Each Fund may write (sell) covered put and call
options and purchase put and call  options on  securities.  Each Fund will write
options on securities for the purpose of increasing its return and/or to protect
the value of its portfolio.  In  particular,  where a Fund writes an option that
expires unexercised or is closed out by the Fund at a profit, it will retain the
premium paid for the option which will increase its gross income and will offset
in part the reduced value of the portfolio  security  underlying the option,  or
the increased cost of portfolio securities to be acquired.  However, the writing
of options  constitutes  only a partial  hedge,  up to the amount of the premium
less any transaction costs. In contrast, if the price of the underlying security
moves adversely to the Fund's position, the option may be exercised and the Fund
will  be  required  to   purchase   or  sell  the   underlying   security  at  a
disadvantageous  price,  which may only be partially offset by the amount of the
premium.  Each Fund may also write  combinations  of put and call options on the
same security,  known as "straddles." Such transactions can generate  additional
premium income but also present increased risk.

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

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

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

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

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

                                        -17-
<PAGE>

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

   
         Futures  Contracts  and  Options  on Futures  Contracts:  Each Fund may
purchase and sell futures contracts on stock indices,  and may purchase and sell
Futures  Contracts  on foreign  currencies  or  indices  of  foreign  currencies
("Futures  Contracts").  Each Fund may also  purchase and write  options on such
Futures Contracts.  Consistent with a Fund's investment objectives and policies,
the Real  Estate  Fund,  the  Special  Opportunities  Fund  and the  Convertible
Securities  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
that may become  available for trading.  These Funds may also purchase and write
options  on such  Futures  Contracts.  All  above-referenced  options on Futures
Contracts are referred to as "Options on Futures Contracts."


         Such  transactions  will be entered  into for  hedging  purposes or for
non-hedging  purposes to the extent  permitted by applicable law. Each Fund will
incur brokerage fees when it purchases and sells Futures Contracts,  and will be
required to maintain margin  deposits.  In addition,  Futures  Contracts  entail
risks. Although the Adviser believes that use of such contracts will benefit the
Funds, if its investment  judgment about the general direction of exchange rates
or the stock market is incorrect,  a Fund's  overall  performance  may be poorer
than if it had not  entered  into any such  contract  and the Fund may realize a
loss.
    

         Purchases  of Options on Futures  Contracts  may  present  less risk in
hedging a Fund's  portfolio than the purchase or sale of the underlying  Futures
Contracts  since the potential loss is limited to the amount of the premium plus
related  transaction costs,  although it may be necessary to exercise the option
to realize any profit, which results in the establishment of a futures position.
The writing of Options on Futures Contracts, however, does not present less risk
than the trading of Futures  Contracts and will constitute only a partial hedge,
up to the  amount  of  the  premium  received.  In  addition,  if an  option  is
exercised, a Fund may suffer a loss on the transaction.

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

         Forward  Contracts:  Each Fund may enter into forward foreign  currency
exchange  contracts  for the  purchase or sale of a fixed  quantity of a foreign
currency at a future date at a price set at the time of the  contract  ("Forward
Contracts"). Each Fund may enter into Forward Contracts for hedging purposes and
for non-hedging  purposes of increasing the Fund's current  income.  By entering
into  transactions  in Forward  Contracts  for hedging  purposes,  a Fund may be
required to forego the benefits of  advantageous  changes in exchange rates and,
in the case of Forward Contracts entered into for non-hedging  purposes,  a Fund
may  sustain  losses  which will  reduce its gross  income.  Such  transactions,
therefore,  could  be  considered  speculative.  Forward  Contracts  are  traded
over-the-counter and not on organized commodities or securities exchanges.  As a
result,  Forward  Contracts  operate in a manner  distinct from  exchange-traded
instruments,  and their use involves  certain risks beyond those associated with
transactions  in Futures  Contracts or options  traded on exchanges.  A 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, a Fund may hold such
currencies  for an  indefinite  period  of time.  A Fund may also  enter  into a
Forward  Contract on one  currency to hedge  against  risk of loss  arising from
fluctuations in the value of a second currency  (referred to as a "cross hedge")
if, in the judgment of the Adviser,  a reasonable  degree of correlation  can be
expected  between  movements in the values of the two currencies.  Each Fund has
established  procedures,  which require use of  segregated  assets or "cover" in
connection with the purchase and sale of such contracts.

         Options on Foreign  Currencies:  Each Fund may also  purchase and write
options on foreign currencies  ("Options on Foreign Currencies") for the purpose
of protecting  against declines in the dollar value of portfolio  securities and
against  increases in the dollar cost of  securities  to be acquired.  As in the
case of other  types of  options,  however,  the writing of an Option on Foreign
Currency will  constitute  only a partial hedge, up to the amount of the premium
received,  and a Fund may be required to purchase or 

                                        -18-
<PAGE>

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 a Fund's position, it may forfeit the entire amount of
the premium paid for the option plus related  transaction costs. A Fund may also
choose, or be required to receive delivery of the foreign currencies  underlying
Options  on  Foreign  Currencies  into  which  it  has  entered.  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, a Fund
may hold such currencies for an indefinite period of time.

INVESTMENT  TECHNIQUES  APPLICABLE TO CERTAIN  FUNDS.  The following  investment
techniques are applicable only to certain Funds, as specified:

   
         Short  Sales:  If  the  Special  Opportunities  Fund,  the  Convertible
Securities  Fund,  the  Science  and  Technology  Fund or the Real  Estate  Fund
anticipates that the price of a security will decline,  it may sell the security
short and borrow the same type of security from a broker or other institution to
complete the sale. A Fund may make a profit or loss  depending  upon whether the
market  price of the security  decreases  or  increases  between the date of the
short sale and the date on which the Fund must  replace the  borrowed  security.
Possible  losses from short sales differ from losses that could be incurred from
a purchase of a  security,  because  losses  from short sales may be  unlimited,
whereas  losses from  purchases can equal only the total amount  invested.  Each
Fund's  short  sales  must be fully  collateralized.  A Fund will not sell short
securities  whose  underlying  value  (minus any  amounts  deposited  as margin)
exceeds 40% of its net assets.

         Mortgage "Dollar Roll"  Transactions:  The Special  Opportunities Fund,
the Convertible Securities Fund and the Real Estate Fund may enter into mortgage
"dollar roll"  transactions with selected banks and  broker-dealers  pursuant to
which  a 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. A 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. In the event that the party with
whom the Fund contracts to replace  substantially similar securities on a future
date fails to deliver such  securities,  the Fund may not be able to obtain such
securities at the price specified in such contract and thus may not benefit from
the price differential between the current sales price and the repurchase price.

         Corporate Asset-Backed Securities:  The Special Opportunities Fund, the
Convertible  Securities  Fund and the Real Estate  Fund may invest in  corporate
asset-backed securities. These securities,  issued by trusts and special purpose
corporations,  are backed by a pool of assets, such as credit card or automobile
loan receivables, representing the obligations of a number of different parties.
    

         Corporate asset-backed  securities present certain risks. For instance,
in the  case of  credit  card  receivables,  these  securities  may not have the
benefit  of  any  security  interest  in the  related  collateral.  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  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.  A 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.

         Zero Coupon Bonds,  Deferred  Interest Bonds and PIK Bonds: The Special
Opportunities Fund, the Convertible Securities Fund and the Real Estate Fund may
invest in zero coupon bonds, deferred interest bonds and payment-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.  A
Fund will accrue income on such investments for tax and accounting purposes,  as
required,  which is distributable to shareholders and which,  because no cash is
received at the time of accrual,  may require the liquidation of other portfolio
securities to satisfy the Fund's distribution obligations.

         Collateralized   Mortgage   Obligations  and  Multiclass   Pass-Through
Securities:  The Special Opportunities Fund, the Convertible Securities Fund and
the Real Estate  Fund each 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, the Federal  National  Mortgage
Association  ("FNMA") or the Federal Home Loan Mortgage  Corporation  ("FHLMC"),
but also may be collateralized  by whole loans or private mortgage  pass-through
securities (such collateral collectively referred to as "Mortgage Assets"). Each
of  these  Funds  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,  authorities 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 a Fund invests, the
investment may be subject to a greater or lesser risk of prepayments  than other
types of mortgage-related securities.

         The Special Opportunities Fund, the Convertible Securities Fund and the
Real Estate 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.

         Stripped  Mortgage-Backed  Securities:  The Special Opportunities Fund,
the Convertible  Securities Fund and the Real Estate Fund may invest 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.

         Loans and Other Direct  Indebtedness:  The Special  Opportunities Fund,
the  Convertible  Securities  Fund and the Real  Estate  Fund may each  invest a
portion of its assets in loans.  By  purchasing a loan, a Fund  acquires some or
all of the  interest  of a bank  or  other  lending  institution  in a loan to a
corporate,  government or other borrower.  Many such loans are secured, and most
impose restrictive covenants which must be met by the borrower.  These loans are
made  generally  to  finance  internal  growth,  mergers,  acquisitions,   stock
repurchases,  leveraged buy-outs and other corporate activities.  Such loans may
be in default at the time of purchase.  A Fund may also purchase  trade or other
claims against companies, which generally represent money owed by the company to
a supplier of goods and  services.  These claims may also be purchased at a time
when the  company is in  default.  Certain of the loans  acquired  by a Fund may
involve revolving credit facilities or other standby financing commitments which
obligate a Fund to pay additional cash on a certain date or on demand.
    

         The  highly  leveraged  nature of many such  loans may make such  loans
especially vulnerable to adverse changes in economic or market conditions. Loans
may not be in the  form of  securities  or may be  subject  to  restrictions  on
transfer,  and only limited  opportunities may exist to resell such instruments.
As a result,  a Fund may be unable to sell such investments at an opportune time
or may have to resell them at less than fair market value.

                                        -20-

         Mortgage Pass-Through  Securities:  The Special Opportunities Fund, the
Convertible  Securities  Fund and the Real  Estate  Fund may invest in  mortgage
pass-through   securities.   Mortgage  pass-through  securities  are  securities
representing  interests  in "pools"  of  mortgage  loans.  Monthly  payments  of
interest and  principal  by the  individual  borrowers  on mortgages  are passed
through  to the  holders  of the  securities  (net of fees paid to the issuer or
guarantor of the  securities) as the mortgages in the underlying  mortgage pools
are paid off.  Payment of principal and interest on some  mortgage  pass-through
securities  (but not the  market  value  of the  securities  themselves)  may be
guaranteed by the full faith and credit of the U.S.  Government  (in the case of
securities  guaranteed  by GNMA);  or  guaranteed  by U.S.  Government-sponsored
corporations   (such  as  FNMA  or  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).

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

         Investment  in Other  Investment  Companies:  The Real  Estate Fund may
invest in other investment companies to the extent permitted by the 1940 Act. If
a Fund invests in such investment  companies,  the Fund's shareholders will bear
not only their  proportionate  share of the  expenses  of that  particular  Fund
(including  operating  expenses  and the fees of the  Adviser),  but  also  will
indirectly bear similar expenses of the underlying investment companies.
    

6.       ADDITIONAL RISK FACTORS

The following discussion of additional risk factors supplements the risk factors
described  above.  Additional  information  concerning risk factors can be found
under the caption "Certain Securities and Investment Techniques" in the SAI.

         Special   Opportunities   Fund:   The  Special   Opportunities   Fund's
investments will be aggressively managed with a higher risk of loss than that of
more  conservatively  managed  portfolios.  Many of the securities  offering the
capital  appreciation sought by the Fund will involve a high degree of risk. The
Fund will seek to reduce risk by  investing  in a number of  securities  markets
(e.g., U.S. Government,  corporate fixed income, equity and foreign markets) and
issuers,  performing  credit  analyses of potential  investments  and monitoring
current developments and trends in both the economy and financial markets.

         Some of the Fund's assets may be invested in  securities  whose issuers
have operating  losses,  substantial  capital  needs,  negative net worth or are
insolvent  or  involved  in  bankruptcy  or  reorganization  proceedings.  It is
difficult to value financially  distressed issuers and to estimate prospects for
their  financial  recovery.  The  issuers  may be unable  to meet  debt  service
requirements  and the  investments may take  considerable  time to appreciate in
value. Some of the securities acquired by the Fund may not be current on payment
of interest or dividends.  In the event that issuers of securities  owned by the
Fund become involved in bankruptcy or other insolvency  proceedings,  additional
risks will be present.  Bankruptcy or other  insolvency  proceedings  are highly
complex, can be very costly and may result in unpredictable outcomes. Bankruptcy
courts  have  extensive  powers  and  under  certain   circumstances  may  alter
contractual obligations of the bankrupt company.

         Since there may be no public  market or only inactive  trading  markets
for some of the  securities in which the Fund invests,  the Fund may be required
to retain such investments for indefinite periods or to sell them at substantial
losses.   Such   securities  may  involve   greater  risks,   often  related  to
creditworthiness,   solvency,   relative  liquidity  of  the  secondary  market,
potential  market losses,  vulnerability  to rising  interest rates and economic
downturns and market price volatility based upon interest rate sensitivity,  all
of  which  may  adversely  affect  the  Fund's  net  asset  value.  This  may be
particularly  true of lower  rated or unrated  securities  in which the 

                                        -21-
<PAGE>

Fund may invest  (see "Lower  Rated  Bonds"  below).  In  addition,  many of the
securities held by the Fund may not have readily available market prices and may
instead be priced by third party pricing  vendors or priced at fair market value
by MFS, subject to the oversight of the Trust's Board of Trustees.

   
         Real Estate Fund:  The Real Estate Fund may be subject to certain risks
similar to those  associated with the direct ownership of real estate because of
its policy of concentration in the securities of companies which are principally
engaged  in the real  estate  industry.  The risks of direct  ownership  of real
estate include: risks related to general, regional and local economic conditions
and  fluctuations in interest  rates;  overbuilding  and increased  competition;
increases  in property  taxes and  operating  expenses;  changes in zoning laws;
heavy cash flow  dependency;  possible lack of  availability  of mortgage funds;
losses due to natural disasters;  regulatory limitations on rents; variations in
market rental rates; and changes in neighborhood  values. In addition,  the Fund
may  incur  losses  due  to  environmental   problems.   If  there  is  historic
contamination  at a site,  the current  owner is one of the parties  that may be
responsible for clean up costs.

         Equity REITs may be affected by changes in the value of the  underlying
property owned by the trusts, while mortgage REITs may be affected by default or
payment  problems  relating  to  underlying  mortgages,  the  quality  of credit
extended and self-liquidation  provisions by which mortgages held may be paid in
full and  distributions  of capital returns may be made at any time.  Equity and
mortgage  REITs  are  dependent  upon the skill of their  individual  management
personnel and generally are not  diversified.  In addition,  equity and mortgage
REITs  could  be   adversely   affected  by  failure  to  qualify  for  tax-free
pass-through of income under the Internal  Revenue Code of 1986, as amended,  or
to maintain their exemptions from registration  under the 1940 Act. By investing
in REITS  indirectly  through  the  Fund,  a  shareholder  will  bear not only a
proportionate  share of the expenses of the Fund, but also  indirectly,  similar
expenses of the REITs, including compensation of management.

         To the  extent  the  Fund is  invested  in debt  securities  (including
asset-backed  securities) or mortgage  REITs,  it will be subject to credit risk
and interest rate risk. Credit risk relates to the ability of the issuer to meet
interest  and  principal  payments  when due.  Interest  rate risk refers to the
fluctuations in the net asset value of any portfolio of fixed income  securities
resulting  solely from the inverse  relationship  between the price and yield of
fixed  income  securities;  that is,  when  interest  rates  rise,  bond  prices
generally fall and conversely,  when interest rates fall, bond prices  generally
rise. In general,  bonds with longer  maturities  are more sensitive to interest
rate changes than bonds with shorter maturities.

         Non-diversification: The Special Opportunities Fund and the Real Estate
Fund are  "non-diversified,"  as that term is defined in the 1940 Act,  but each
such Fund intends to qualify as a  "regulated  investment  company"  ("RIC") for
federal income tax purposes.  This means, in general, that although more than 5%
of the Fund's  total  assets may be  invested  in the  securities  of one issuer
(including  a foreign  government),  at the close of each quarter of its taxable
year,  the aggregate  amount of such holdings may not exceed 50% of the value of
its total  assets,  and no more than 25% of the value of its total assets may be
invested  in  the  securities  of  a  single  issuer.   To  the  extent  that  a
non-diversified  Fund at times may hold the  securities  of a smaller  number of
issuers  than if it were  "diversified"  (as defined in the 1940 Act),  the Fund
will at such  times be subject to  greater  risk with  respect to its  portfolio
securities  than a fund that invests in a broader range of  securities,  because
changes in the financial  condition or market  assessment of a single issuer may
cause greater fluctuations in the Fund's total return and the net asset value of
its shares.
    

         Science  and  Technology   Fund:  An  investment  in  the  Science  and
Technology  Fund may  involve  significantly  greater  risks and  therefore  may
experience  greater  volatility than an investment in a fund with a more broadly
diversified  investment  mandate.  Because the Science and Technology  Fund will
primarily  invest in  companies  which  the  Adviser  expects  to  benefit  from
scientific  and  technological   advancements  and   improvements,   the  Fund's
investment performance will be closely tied to the performance of companies in a
limited  number of  industries.  Companies in a single  industry are often faced
with the same obstacles, issues and regulatory burdens, and their securities may
react  similarly and more in unison to these or other market  conditions.  These
price  movements  may have a  disproportionate  impact on the Fund's  investment
performance given its narrow industry focus.

         Emerging  Growth  Companies:  Investing  in emerging  growth  companies
involves  greater risk than is  customarily  associated  with  investing in more
established  companies.  Emerging  growth  companies  often have limited product
lines, markets or financial  resources,  and they may be dependent on one-person
management.  The securities of emerging growth  companies may be subject to more
abrupt or erratic market  movements than securities of larger,  more established
companies or the market averages in general.  Similarly,  many of the securities
offering  the  capital  appreciation  sought by the Funds will  involve a higher
degree of risk than would established growth stocks.

         Fixed Income  Securities:  To the extent a Fund invests in fixed income
securities,  the net asset value of the Fund may change as the general levels of
interest rates fluctuate. When interest rates decline, the value of fixed income
securities  can be expected to rise.  Conversely,  when interest rates rise, the
value of fixed income  securities can be expected to decline.  The Funds are 

                                        -22-
<PAGE>

not subject to  restrictions  on the  maturities of the fixed income  securities
they hold. A Fund's  investments in fixed income securities with longer terms to
maturity  are  subject  to  greater  volatility  than  the  Fund's  shorter-term
obligations.

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

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

   
         Lower Rated Bonds:  The Special  Opportunities  Fund,  the  Convertible
Securities  Fund, the Science and  Technology  Fund and the Real Estate Fund may
invest in fixed income and convertible  securities,  rated Baa by Moody's or BBB
by  S&P,  Fitch  or Duff &  Phelps  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 securities.

         These Funds may also invest in securities  rated Ba or lower by Moody's
or BB or lower by S&P, Fitch or Duff & Phelps and comparable  unrated securities
(commonly known as "junk bonds") to the extent described above. These securities
are considered  speculative and, while generally  providing  greater income than
investments in higher rated  securities,  will involve greater risk of principal
and income (including the possibility of default or bankruptcy of the issuers of
such securities) and may involve greater  volatility of price (especially during
periods of economic  uncertainty or change) than securities in the higher rating
categories.  However,  since yields vary over time, no specific  level of income
can ever be assured.  These lower rated high  yielding  fixed income  securities
generally tend to reflect economic changes and short-term corporate and industry
developments  to a greater  extent  than  higher  rated  securities  which react
primarily to fluctuations in the general level of interest rates (although these
lower rated fixed  income  securities  are also  affected by changes in interest
rates,  the market's  perception  of their credit  quality,  and the outlook for
economic  growth).  In the past,  economic  downturns or an increase in interest
rates have, under certain circumstances, caused a higher incidence of default by
the issuers of these  securities and may do so in the future,  especially in the
case of highly leveraged issuers. During certain periods, the higher yields on a
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,  a Fund
may continue to earn the same level of interest income while its net asset value
declines  due to  portfolio  losses,  which  could  result in an increase in the
Fund's yield  despite the actual loss of  principal.  The market for these lower
rated fixed income  securities may be less liquid than the market for investment
grade fixed income securities,  and judgment may at times play a greater role in
valuing  these  securities  than in the case of  investment  grade fixed  income
securities.  Changes in the value of securities  subsequent to their acquisition
will not affect cash income or yield to maturity to a Fund but will be reflected
in the net asset value of shares of the Fund.
    

         Foreign  Securities:  Each Fund may  invest in dollar  denominated  and
non-dollar  denominated foreign  securities.  Investing in securities of foreign
issuers  generally  involves risks not ordinarily  associated  with investing in
securities  of  domestic  issuers.  These  include  changes in  currency  rates,
exchange control  regulations,  securities  settlement  practices,  governmental
administration  or economic or monetary  policy (in the United States or abroad)
or  circumstances  in  dealings  between  nations.  Costs  may  be  incurred  in
connection with conversions between various currencies.  Special  considerations
may  also  include  more  limited  information  about  foreign  issuers,  higher
brokerage  costs,  different  accounting  standards and thinner trading markets.
Foreign  securities  markets may also be less  liquid,  more  volatile  and less
subject to government  supervision  than in the United  States.  Investments  in
foreign  countries could be affected by other factors  including  expropriation,
confiscatory  taxation  and  potential  difficulties  in  enforcing  contractual
obligations and could be subject to extended settlement  periods.  Each 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.  

                                        -24-
<PAGE>

dollars at a later date, based on anticipated  changes in the relevant  exchange
rate.  Each Fund may also hold foreign  currency in  anticipation  of purchasing
foreign securities.

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

         Emerging Market  Securities:  Each Fund may invest in emerging markets.
In addition to the general risks of investing in foreign securities, investments
in  emerging  markets  involve  special  risks.  Securities  of many  issuers in
emerging  markets  may be less  liquid  and more  volatile  than  securities  of
comparable domestic issuers. These securities may be considered speculative and,
while   generally   offering   higher  income  and  the  potential  for  capital
appreciation,  may present significantly greater risk. Emerging markets may have
different clearance and settlement procedures, and in certain markets there have
been times  when  settlements  have been  unable to keep pace with the volume of
securities  transactions,  making it  difficult  to conduct  such  transactions.
Delays in  settlement  could result in  temporary  periods when a portion of the
assets of a Fund is uninvested and no return is earned thereon. The inability of
a Fund to make intended  securities  purchases due to settlement  problems could
cause a Fund to miss attractive investment  opportunities.  Inability to dispose
of portfolio  securities due to settlement  problems could result in losses to a
Fund due to subsequent declines in value of the portfolio  security,  a decrease
in the level of liquidity in the Fund's  portfolio,  or, if the Fund has entered
into a contract  to sell the  security,  possible  liability  to the  purchaser.
Certain markets may require payment for securities before delivery,  and in such
markets a Fund bears the risk that the securities will not be delivered and that
the Fund's payments will not be returned.  Securities prices in emerging markets
can be  significantly  more volatile than in the more  developed  nations of the
world,  reflecting the greater  uncertainties  of investing in less  established
markets and economies.  In particular,  countries with emerging markets may have
relatively  unstable  governments,   present  the  risk  of  nationalization  of
businesses,  restrictions on foreign ownership,  or prohibitions on repatriation
of assets,  and may have less  protection of property rights than more developed
countries. The economies of countries with emerging markets may be predominantly
based on only a few industries,  may be highly vulnerable to changes in local or
global trade  conditions,  and may suffer from extreme and volatile debt burdens
or  inflation  rates.  Local  securities  markets  may  trade a small  number of
securities  and may be unable to respond  effectively  to  increases  in trading
volume,  potentially making prompt liquidation of substantial holdings difficult
or impossible at times. Securities of issuers located in countries with emerging
markets  may have  limited  marketability  and may be subject to more  abrupt or
erratic movements in price.

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

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

         Portfolio  Trading:  Each Fund  intends  to  manage  its  portfolio  by
buying and selling  securities,  as well as holding  securities to maturity,  to
help attain its investment objective and policies.

         Each  Fund  will  engage  in   portfolio   trading  if  it  believes  a
transaction,  net of costs (including custodian charges), will help in attaining
its investment objective. In trading portfolio securities,  a 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 Funds in trading portfolio securities,  see "Portfolio  Transactions
and Brokerage  Commissions" in the SAI.  Because each Fund is expected to have a
portfolio  turnover  rate  of  up  to  200%  during  its  current  fiscal  year,
transaction  costs  incurred  by each Fund and the  realized  capital  gains and
losses of each Fund may be  greater  than that of a fund with a lower  portfolio
turnover rate.

         The primary  consideration in placing portfolio  security  transactions
with  broker-dealers  for execution is to obtain,  and maintain the availability
of,  execution at the most  favorable  prices and in the most  effective  manner
possible. Consistent with the foregoing primary consideration, the Conduct Rules
of the National  Association of Securities  Dealers,  Inc. (the "NASD") and such
other  policies  as the  Trustees  of the Trust may  determine,  the Adviser may
consider  sales of  shares  of other  investment  company  clients  of MFD,  the
distributor  of shares of the  Trust  and of the MFS  Family of Funds  (the "MFS
Funds"),  as a factor in the selection of  broker-dealers to execute each Fund's
portfolio  transactions.  From  time to time  the  Adviser  may  direct  certain
portfolio transactions 

                                        -25-

to broker-dealer  firms which, in turn, have agreed to pay a portion of a Fund's
operating expenses (e.g., fees charged by the custodian of the Fund's assets).

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

         The SAI  includes  a  discussion  of other  investment  policies  and a
listing of specific investment restrictions which govern the investment policies
of each Fund.  The  specific  investment  restrictions  listed in the SAI may be
changed without  shareholder  approval unless indicated otherwise (see the SAI).
Except with respect to a Fund's  policy on borrowing  and  investing in illiquid
securities,  a Fund's investment limitations,  policies and rating standards are
adhered to at the time of purchase or utilization of assets; a subsequent change
in circumstances will not be considered to result in a violation of policy.

7.       MANAGEMENT OF THE FUNDS

   
Investment  Adviser  -- The  Adviser  manages  each Fund  pursuant  to  separate
Investment Advisory  Agreements,  dated January 2, 1996 with respect to the Core
Growth Fund and the Special  Opportunities Fund, January 2, 1997 with respect to
the  Convertible  Securities  Fund,  the  Blue  Chip  Fund and the  Science  and
Technology  Fund, and March 16, 1998 with respect to the Real Estate Fund. Under
the Advisory Agreements,  the Adviser provides each Fund with overall investment
advisory services.  Subject to such policies as the Trustees may determine,  the
Adviser makes investment decisions for each Fund. For its services,  the Adviser
is entitled to receive a management fee, computed and paid monthly, in an amount
listed below per annum of the average daily net assets of such Fund:

  Core           Special        Convertible      Blue     Science and     Real
 Growth       Opportunities      Securities      Chip      Technology    Estate
  Fund            Fund              Fund         Fund         Fund        Fund

For the period from the  commencement  of investment  operations,  to the fiscal
year end of August  31,  1997,  the  Adviser  has  waived  its right to  receive
management  fees from each Fund.  The Adviser is currently  waiving its right to
receive management fees from each Fund.

The identity and  background  of the portfolio  manager(s)  for each Fund is set

                                         the Adviser since 1990.

    
   
MFS also  serves  as  investment  adviser  to each of the other 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 Variable Insurance Trust,
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.),  a  subsidiary  of Sun Life  Assurance  Company of Canada  ("Sun
Life"), in connection with the sale of various fixed/variable annuity contracts.
MFS and its wholly owned subsidiary,  MFS Institutional Advisors,  Inc., provide
investment advice to substantial private clients.

MFS is  America's  oldest  mutual  fund  organization.  MFS and its  predecessor
organizations  have a  history  of money  management  dating  from  1924 and the
founding of the first mutual fund in the U.S.,  Massachusetts  Investors  Trust.
Net assets under the management of the MFS organization were approximately $72.0
billion on behalf of approximately  2.8 million investor  accounts as of January
31, 1998. As of such date,  the MFS  organization  managed  approximately  $20.8
billion of assets  invested in fixed income  funds and fixed income  portfolios,
approximately  $47.2  billion  of assets  invested  in foreign  securities,  and
approximately  $7.2 billion of assets  invested in equity  securities.  MFS is a
subsidiary of Sun Life of Canada (U.S.) Financial Holdings,  Inc., which in turn
is an indirect  wholly owned  subsidiary  of Sun Life.  The Directors of MFS are
John W. Ballen,  Jeffrey L. Shames,  Arnold D. Scott, Donald A. Stewart and John
D. McNeil.  Mr. Ballen is an Executive  Vice President of MFS, Mr. Shames is the
Chairman,  President  and Chief  Executive  Officer of MFS and Mr.  Scott is the
Secretary  and a Senior  Executive  Vice  President of MFS.  Messrs.  McNeil and
Stewart are the Chairman and  President of Sun Life,  respectively.  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 to the
Chairman of Sun Life.

Jeffrey L.  Shames,  the  President,  Chief  Executive  Officer,  Chairman and a
Director of MFS, is also a Trustee of the Trust.  W. Thomas  London,  Stephen E.
Cavan,  James  O.  Yost,  Mark E.  Bradley,  Ellen  M.  Moynihan  and  James  R.
Bordewick, Jr., all of whom are officers of MFS, are officers of the Trust.
    

In certain  instances  there may be  securities  which are suitable for a Fund's
portfolio as well as for  portfolios of other clients of MFS. Some  simultaneous
transactions are inevitable when several clients receive  investment advice from
MFS,  particularly  when the same security is suitable for more than one client.
While in some cases this  arrangement  could  have a  detrimental  effect on the
price or  availability  of the security as far as a Fund is concerned,  in other
cases, however, it may produce increased investment opportunities for the Funds.

Administrator - MFS provides the Fund with certain financial, legal, compliance,
shareholder  communications  and other  administrative  services  pursuant  to a
Master Administrative  Services Agreement dated March 1, 1997, as amended. Under
this  Agreement,  the Fund pays MFS an  administrative  fee of up to 0.015%  per
annum of the Fund's  average  daily net assets.  This fee  reimburses  MFS for a
portion of the costs it incurs to provide such services.

Distributor  - MFD, a wholly  owned  subsidiary  of MFS, is the  distributor  of
shares of each  Fund and also  serves  as  distributor  of 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
and certain other services for each Fund.

8.       INFORMATION CONCERNING SHARES OF THE FUNDS

PURCHASES

Class A, Class B and Class C shares of each Fund may be  purchased at the public
offering price through any dealer.  Dealers may also charge their customers fees
relating  to  investments  in  each  Fund.  As used  in the  Prospectus  and any
appendices  thereto,  the  term  "dealer"  includes  any  broker,  dealer,  bank
(including bank trust departments),  registered  investment  adviser,  financial
planner and any other financial institutions having a selling agreement or other
similar agreement with MFD.

This  Prospectus  offers  Class A,  Class B and Class C shares  which bear sales
charges and distribution fees in different forms and amounts, as described below
(currently, only Class A shares are available for sale):

CLASS A SHARES:  Class A shares are generally offered at net asset value plus an
initial  sales  charge,  but in certain  cases are  offered  at net asset  value
without an initial sales charge but subject to a CDSC.

         Purchases Subject to Initial Sales Charge.

   
         Class A shares of each Fund except for the Real Estate Fund are offered

and MFD retains  approximately 3/4 of 1% of the public offering price. The sales
charge  may vary  depending  on the  number  of  shares  of each Fund as

well as certain  other MFS Funds owned or being  purchased,  the existence of an
agreement to purchase  additional  shares during a 13-month  period (or 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 Purchase
privileges by which the sales charge may be reduced is set forth in the SAI.

following  five  circumstances,  Class A shares of each Fund are also offered at
net asset value without an initial sales charge but subject to a CDSC,  equal to
1% of the lesser of the value of the shares  redeemed  (exclusive  of reinvested
dividend and capital gain  distributions)  or the total cost of such shares,  in
the event of a share redemption within 12 months following the purchase:

                  purchases  by the  retirement  plan of Class A  shares  of the
                  Funds in the MFS Funds  will be in an  aggregate  amount of at
                  least  $250,000  within  a  reasonable   period  of  time,  as
                  determined by MFD in its sole discretion;

         (iii)    on investments in Class A shares by certain  retirement  plans

                  Participant  Recordkeeping  System"); (b) the plan establishes
                  an account with the  Shareholder  Servicing  Agent on or after
                  July  1,  1996;  and  (c)  the  aggregate   purchases  by  the
                  retirement  plan of Class A shares  of the MFS  Funds  will be
                  in  an  aggregate   amount  of  at  least  $500,000  within  a
                  reasonable  period of time,  as  determined by MFD in its sole
                  discretion;

                  value of $500,000  or more  invested in shares of any class or
                  classes of the MFS Funds;  the  retirement  plan will  qualify
                  under  this  category  only  if the  plan  or  its  sponsoring
                  organization  informs the  Shareholder  Servicing  Agent prior

                  $500,000  or more  invested  in shares of any class or classes
                  of the MFS  Funds;  the  Shareholder  Servicing  Agent  has no
                  obligation  independently  to  determine  whether  such a plan
                  qualifies under this category; and

         (v)      on investments in Class A shares by certain  retirement  plans
                  subject  to ERISA,  if:  (a) the plan  establishes  an account
                  with the  Shareholder  Servicing  Agent  on or  after  July 1,
                  1997;  (b) such  plan's  records  are  maintained  on a pooled
                  basis  by  the  Shareholder   Servicing  Agent;  and  (c)  the
                  sponsoring  organization  demonstrates to the  satisfaction of
                  MFD that,  at the time of purchase,  the employer has at least
                  200 eligible  employees and the plan has  aggregate  assets of
                  at least $2,000,000.

         In the case of such  purchases,  MFD will pay commissions to dealers on
new investments in Class A shares made through such dealers, as follows:

         Commission Paid by MFD to Dealers     Cumulative Purchase Amount

                   1.00%.................  On the first $2,000,000, plus
                   0.80%.................  Over $2,000,000 to $3,000,000, plus
                   0.50%.................  Over $3,000,000 to $50,000,000, plus
                   0.25%.................  Over $50,000,000

   
         For  purposes of  determining  the level of  commissions  to be paid to
dealers  with  respect  to a  shareholder's  new  investment  in Class A shares,
purchases for each shareholder account (and certain other accounts for which the
shareholder is a record or beneficial holder) will be aggregated over a 12-month
period (commencing from the date of the first such purchase).
    

See "Redemptions  and Repurchases - Contingent  Deferred Sales Charge" below for
further discussion of the CDSC.

         Waivers of Initial Sales Charge and CDSC. In certain circumstances, the
initial  sales  charge  imposed  upon  purchases  of Class A shares and the CDSC
imposed upon redemptions of Class A shares are waived.  These  circumstances are
described in Appendix A to this Prospectus.  In addition to these circumstances,
the CDSC imposed upon the redemption of Class A shares is waived with respect to
shares held by certain retirement plans qualified under Section 401(a) or 403(b)
of the Internal  Revenue Code of 1986, as amended (the  "Code"),  and subject to
ERISA, where:

         (i)      the retirement plan and/or  sponsoring  organization  does not
                  subscribe to the MFS Participant Recordkeeping System; and

         (ii)     the   retirement   plan   and/or    sponsoring    organization
                  demonstrates  to the  satisfaction  of, and  certifies to, the
                  Shareholder  Servicing  Agent that the retirement plan has, at
                  the  time  of  certification,  or  will  have  pursuant  to  a
                  purchase order placed with the  certification,  a market value
                  of  $500,000  or more  invested  in  shares  of any  class  or
                  classes  of the MFS  Funds  and  aggregate  assets of at least
                  $10 million;

provided,  however,  that the CDSC will not be waived (i.e., it will be imposed)
(a) with  respect  to plans  which  establish  an account  with the  Shareholder
Servicing Agent on or after November 1, 1997, in the event that the plan makes a
complete  redemption of all of its shares in the MFS Funds,  or (b) with respect
to plans which established an account with the Shareholder Servicing Agent prior
to November 1, 1997,  in the event that there is a change in law or  regulations
which results in a material  adverse change to the tax advantaged  nature of the
plan, or in the event that the plan and/or sponsoring organization:  (i) becomes
insolvent  or  bankrupt;  (ii) is  terminated  under ERISA or is  liquidated  or
dissolved;  or (iii) is acquired by, merged into, or consolidated with any other
entity.

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

                                                      CONTINGENT
YEAR OF REDEMPTION AFTER                            DEFERRED SALES
         PURCHASE                                      CHARGE

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

The CDSC  imposed  is  assessed  against  the  lesser of the value of the shares
redeemed  (exclusive of reinvested  dividends and capital gain distributions) or
the total cost of such  shares.  No CDSC is  assessed  against  shares  acquired
through the automatic  reinvestment of dividends or capital gain  distributions.
See "Redemptions and Repurchases - Contingent Deferred Sales Charge" below for
further discussion of the CDSC.

Except as described  below,  MFD will pay commissions to dealers of 3.75% of the
purchase  price of Class B  shares  purchased  through  dealers.  MFD will  also
advance to  dealers  the first  year  service  fee  payable  under  each  Fund's
Distribution  Plan (see  "Distribution  Plan" below) at a rate equal to 0.25% of
the purchase price of such shares.  Therefore, the total amount paid to a dealer
upon  the  sale of  Class B shares  is 4% of the  purchase  price of the  shares
(commission  rate of 3.75%  plus a service  fee  equal to 0.25% of the  purchase
price).

Class B shares  purchased by a  retirement  plan whose  sponsoring  organization
subscribes to the MFS Participant Recordkeeping System and which has established
its account with the Shareholder  Servicing Agent on or after July 1, 1996, will
be subject to the CDSC described  above,  only under limited  circumstances,  as
explained  below under  "Waivers of CDSC." With respect to such  purchases,  MFD
pays an amount to dealers  equal to 3.00% of the amount  purchased  through such
dealers (rather than the 4.00% payment described above), which is comprised of a
commission of 2.75% plus the  advancement of the first year service fee equal to
0.25% of the purchase  price  payable  under each Fund's  Distribution  Plan. As
discussed  above,  such retirement plans are eligible to purchase Class A shares
of the Fund at net asset value  without an initial sales charge but subject to a
1% CDSC if the plan has, at the time of purchase,  a market value of $500,000 or
more invested in shares of any class or classes of the MFS Funds. In this event,
the plan or its sponsoring  organization should inform the Shareholder Servicing
Agent that the plan is eligible to purchase  Class A shares under this category;
the  Shareholder  Servicing Agent has no obligation  independently  to determine
whether such a plan  qualifies  under this  category for the purchase of Class A
shares.

         Waivers  of CDSC.  In  certain  circumstances,  the CDSC  imposed  upon
redemption  of Class B shares is waived.  These  circumstances  are described in
Appendix A to this  Prospectus.  In  addition to these  circumstances,  the CDSC
imposed upon the  redemption  of Class B shares is waived with respect to shares
held by a retirement plan whose  sponsoring  organization  subscribes to the MFS
Participant  Recordkeeping  System and which has established an account with the
Shareholder  Servicing Agent on or after July 1, 1996; provided,  however,  that
the CDSC will not be waived  (i.e.,  it will be imposed) in the event that there
is a change in law or regulations  which results in a material adverse change to
the tax  advantaged  nature of the plan,  or in the event  that the plan  and/or
sponsoring  organization:  (i) becomes insolvent or bankrupt; (ii) is terminated
under ERISA or is liquidated or dissolved; or (iii) is acquired by, merged into,
or consolidated with any other entity.

         Conversion  of Class B Shares.  Class B shares of each Fund that remain
outstanding for approximately  eight years will convert to Class A shares of the
same 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 each  Fund's  Distribution
Plan.  See  "Distribution  Plan" below.  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 but are subject to a CDSC of 1.00% upon redemption during the first
year.  Class C shares do not convert to any other  class of shares.  The maximum
investment in Class C shares is up to $1,000,000 per transaction.

The CDSC  imposed  is  assessed  against  the  lesser of the value of the shares
redeemed  (exclusive of reinvested  dividend and capital gain  distributions) or
the total cost of such  shares.  No CDSC is  assessed  against  shares  acquired
through the automatic  reinvestment  of dividend or capital gain  distributions.
See "Redemptions and Repurchases - Contingent Deferred Sales Charge" below for
further discussion of the CDSC.

MFD will pay dealers  1.00% of the  purchase  price of Class C shares  purchased
through  dealers and, as  compensation  therefor,  MFD will retain the 1.00% per
annum  distribution and service fee paid under each Fund's  Distribution Plan to
MFD for the first year after purchase (see "Distribution Plan" below).

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  recordkeeping  program made  available  by the  Shareholder
Servicing Agent.

         Waivers  of CDSC:  In  certain  circumstances,  the CDSC  imposed  upon
redemption  of Class C shares is waived.  These  circumstances  are described in
Appendix A to this Prospectus.

GENERAL:  The  following  information  applies to  purchases  of all  classes of
each Fund's shares.

         Minimum  Investment.  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
Individual Retirement Accounts ("IRAs")) involving the submission of investments
by means of group  remittal  statements  are subject to a $50 minimum on initial
and additional  investments per account. The minimum initial investment for IRAs
is $250 per account and the minimum  additional  investment  is $50 per account.
Accounts being established for participation in the Automatic  Exchange Plan are
subject to a $50  minimum on initial and  additional  investments  per  account.
There  are  also  other  limited   exceptions  to  these  minimums  for  certain
tax-deferred retirement programs. Any minimums may be changed at any time at the
discretion of MFD. Each Fund reserves the right to cease  offering its shares at
any time.

                                        -30-
<PAGE>

         Subsequent  Investment  by  Telephone.  Each  shareholder  may purchase
additional shares of any MFS Fund by telephoning the Shareholder Servicing agent
toll-free at (800) 225-2606.  The minimum purchase amount is $50 and the maximum
purchase amount is $100,000.  Shareholders  wishing to avail  themselves of this
telephone  purchase  privilege  must so elect on their Account  Application  and
designate  thereon a bank and account number from which  purchases will be made.
If a telephone  purchase request is received by the Shareholder  Servicing Agent
on any  business  day  prior to the close of  regular  trading  on the  Exchange
(generally, 4.00 p.m., Eastern time), the purchase will occur at the closing net
asset value of the shares purchased on that day. The Shareholder Servicing Agent
may be liable for any losses resulting from unauthorized  telephone transactions
if it does not follow 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.

         Right to Reject Purchase Orders/Market Timing.  Purchases and exchanges
should be made for investment purposes only. Each Fund and MFD each reserves the
right to restrict or to reject any specific purchase or exchange request. In the
event that a Fund or MFD rejects an exchange request, neither the redemption nor
the purchase side of the exchange will be processed.

The Funds are not designed for professional market timing organizations or other
entities  using  programmed  or frequent  exchanges.  The Funds define a "market
timer"  as an  individual,  or  organization  acting  on  behalf  of one or more
individuals,  if (i) the individual or organization makes three or more exchange
requests  out of a Fund per  calendar  year  and  (ii) any one of such  exchange
requests  represents  shares equal in value to 1/2 of 1% or more of a Fund's net
assets at the time of the request.  Accounts under common  ownership or control,
including  accounts  administered  by  market  timers,  will be  aggregated  for
purposes of this definition.

As noted above,  the Funds and MFD each reserves the right to reject or restrict
any specific purchase and exchange request and, in addition, may impose specific
limitations  with respect to market timers,  including  delaying for up to seven
days the purchase side of an exchange  request by market timers or  specifically
rejecting or  otherwise  restricting  purchase  and exchange  requests by market
timers.  In the event that any  individual or entity is  determined  either by a
Fund or MFD, in its sole  discretion,  to be a market  timer with respect to any
calendar  year,  the Fund and/or MFD will reject all exchange  requests into the
Fund during the  remainder of that calendar  year.  Other funds in the MFS Funds
may have  different  and/or more  restrictive  policies  with  respect to market
timers than the Funds. These policies are disclosed in the prospectuses of these
other MFS Funds.

         Dealer  Concessions.  Dealers may receive  different  compensation with
respect to sales of Class A, Class B and Class C shares. In addition,  from time
to time,  MFD may pay dealers  100% of the  applicable  sales charge on sales of
Class A shares of  certain  specified  MFS Funds  sold by such  dealer  during a
specified  sales period.  In addition,  MFD or its affiliates  may, from time to
time, pay dealers an additional commission equal to 0.50% of the net asset value
of all of the Class B and/or Class C shares of certain  specified MFS Funds sold
by such dealer during a specified sales period. In addition,  from time to time,
MFD,  at its  expense,  may  provide  additional  commissions,  compensation  or
promotional incentives  ("concessions") to dealers which sell or arrange for the
sale of shares of a Fund. Such concessions provided by MFD may include financial
assistance to dealers in connection  with  preapproved  conferences or seminars,
sales or training  programs  for invited  registered  representatives  and other
employees,   payment  for  travel  expenses,   including  lodging,  incurred  by
registered  representatives  and other  employees  for such seminars or training
programs, seminars for the public, advertising and sales campaigns regarding one
or more MFS Funds, and/or other dealer-sponsored  events. From time to time, MFD
may make expense  reimbursements  for special training of a dealer's  registered
representatives  and  other  employees  in  group  meetings  or to help  pay the
expenses of sales contests.  Other  concessions may be offered to the extent not
prohibited by state laws or any self-regulatory agency, such as the NASD.

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

         Restrictions on Activities of National Banks.  The  Glass-Steagall  Act
prohibits national banks from engaging in the business of underwriting,  selling
or distributing  securities.  Although the scope of the prohibition has not been
clearly  defined,  MFD  believes  that such Act should not  preclude  banks from
entering into agency  agreements with MFD. 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 in
respect of  shareholders  who invested in a Fund through a national  bank. 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.

                                        -31-

EXCHANGES

Subject to the  requirements  set forth  below,  some or all of the shares in an
account with a Fund for which  payment has been  received by the Fund (i.e.,  an
established account) may be exchanged for shares of the same class of any of the
other MFS Funds at net asset value (if available for sale).  Shares of one class
may not be exchanged for shares of any other class.

EXCHANGES AMONG MFS FUNDS (excluding  exchanges from MFS money market funds): No
initial sales charge or CDSC will be imposed in connection with an exchange from
shares of an MFS Fund to shares of any other MFS Fund,  except  with  respect to
exchanges  from an MFS money market fund to another MFS Fund which is not an MFS
money  market fund  (discussed  below).  With  respect to an exchange  involving
shares  subject to a CDSC,  the CDSC will be  unaffected by the exchange and the
holding  period  for  purposes  of  calculating  the CDSC will carry over to the
acquired shares.

EXCHANGES FROM AN MFS MONEY MARKET FUND: Special rules apply with respect to the
imposition of an initial sales charge or a CDSC for exchanges  from an MFS money
market fund to another  MFS Fund which is not an MFS money  market  fund.  These
rules are described under the caption  "Exchanges" in the  Prospectuses of those
MFS money market funds.

EXCHANGES  INVOLVING THE MFS FIXED FUND:  Class A shares of any MFS Fund held by
certain  qualified  retirement plans may be exchanged for units of participation
of the MFS Fixed Fund (a bank  collective  investment  fund) (the "Units"),  and
Units may be  exchanged  for Class A shares of any MFS  Fund.  With  respect  to
exchanges  between  Class A shares  subject to a CDSC and  Units,  the CDSC will
carry  over to the  acquired  shares  or  Units  and will be  deducted  from the
redemption  proceeds  when  such  shares  or Units  are  subsequently  redeemed,
assuming the CDSC is then  payable  (the period  during which the Class A shares
and the Units were held will be  aggregated  for  purposes  of  calculating  the
applicable CDSC). In the event that a shareholder  initially purchases Units and
then  exchanges into Class A shares subject to an initial sales charge of an MFS
Fund, the initial sales charge shall be due upon such exchange,  but will not be
imposed with respect to any subsequent exchanges between such Class A shares and
Units with respect to shares on which the initial  sales charge has already been
paid.  In the  event  that a  shareholder  initially  purchases  Units  and then
exchanges  into Class A shares subject to a CDSC of an MFS Fund, the CDSC period
will commence upon such exchange, and the applicability of the CDSC with respect
to subsequent  exchanges  shall be governed by the rules set forth above in this
paragraph.

GENERAL:  A  shareholder  should read the  prospectus of the other MFS Funds and
consider the differences in objectives,  policies and restrictions before making
any exchange.  Exchanges will be made only after  instructions  in writing or by
telephone (an "Exchange Request") are received for an established account by the
Shareholder Servicing Agent in proper form (i.e., if in writing -- signed by the
record owner(s) exactly as the shares are registered;  if by telephone -- proper
account identification is given by the dealer or shareholder of record) and each
exchange must involve either shares having an aggregate value of at least $1,000
($50 in the case of retirement plan participants whose sponsoring  organizations
subscribe  to  the  MFS  FUNDamental  401(k)  Plan  or  another  similar  401(k)
recordkeeping  system made available by the Shareholder  Servicing Agent) or all
the shares in the account. If an Exchange Request is received by the Shareholder
Servicing Agent on any business day prior to the close of regular trading on the
Exchange  (generally,  4:00 p.m., Eastern time), the exchange will occur on that
day if all the requirements set forth above have been complied with at that time
and subject to the Fund's  right to reject  purchase  orders.  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 dealers or the Shareholder Servicing Agent.
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.

REDEMPTIONS AND REPURCHASES

A shareholder may withdraw all or any portion of the value of his account on any
date on which a Fund is open for business by redeeming shares at their net asset
value (a  redemption)  or by selling  such shares to a Fund  through a dealer (a
repurchase).  Certain  redemptions and repurchases  are,  however,  subject to a
CDSC. See "Contingent  Deferred Sales Charge" below. Because the net asset value
of shares of the  account  fluctuates,  redemptions  or  repurchases,  which are
taxable  transactions,   are  likely  to  result  in  gains  or  losses  to  the
shareholder.  When a  shareholder  withdraws  an amount  from his  account,  the
shareholder  is deemed to have  tendered for  redemption a sufficient  number of
full and  fractional  shares in his account to cover the amount  withdrawn.  The
proceeds of a redemption or repurchase  will normally be available  within seven
days,  except for shares  purchased or received in exchange for shares purchased
by check (including certified checks or cashier's checks). Payment of redemption
proceeds may be delayed for up to 15 days from the purchase date in an effort to
assure that such check has cleared.

                                        -32
<PAGE>

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

REDEMPTION BY TELEPHONE:  Each shareholder may redeem an amount from his account
by telephoning  the  Shareholder  Servicing  Agent  toll-free at (800) 225-2606.
Shareholders  wishing to avail themselves of this telephone redemption privilege
must so elect on their Account Application, designate thereon a 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 and the amount of any income tax
required to be withheld, are mailed by check to the designated account,  without
charge,  if the  redemption  proceeds  do not  exceed  $1,000,  and are wired in
federal  funds to the  designated  account  if the  redemption  proceeds  exceed
$1,000.  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 may
be liable for any losses resulting from unauthorized  telephone  transactions if
it does not follow 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.

REPURCHASE THROUGH A DEALER: If a shareholder desires to sell his shares through
his dealer (a repurchase), the shareholder can place a repurchase order with his
dealer,  who may charge  the  shareholder  a fee.  If the  dealer  receives  the
shareholder's  order prior to the close of regular  trading on the  Exchange and
communicates  it to MFD  before  the  close of  business  on the same  day,  the
shareholder  will receive the net asset value calculated on that day, reduced by
the amount of any  applicable  CDSC and the amount of any income tax required to
be withheld.

CONTINGENT  DEFERRED  SALES CHARGE:  Investments in Class A, Class B and Class C
shares ("Direct  Purchases") will be subject to a CDSC for a period of: (i) with
respect to Class A and Class C shares,  12 months (however,  the CDSC on Class A
shares is only  imposed with respect to purchases of $1 million or more of Class
A shares or purchases by certain  retirement  plans of Class A shares);  or (ii)
with  respect to Class B shares,  six years.  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 C and 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 each 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 of shares represented by Direct Purchases exceeds
the  sum of the  six  calendar  year  aggregations  (12  months  in the  case of
purchases  of Class C shares and of  purchases  of $1 million or more of Class A
shares or  purchases  by certain  retirement  plans of Class A shares) of Direct
Purchases may be redeemed without charge ("Free Amount").  Moreover,  no CDSC is
ever assessed on additional  shares acquired through the automatic  reinvestment
of dividends or capital gain distributions ("Reinvested Shares").  Therefore, at
the time of redemption of a particular class, (i) any Free Amount is not subject
to the CDSC and (ii) the  amount  of the  redemption  equal to the  then-current
value of Reinvested  Shares is not subject to the CDSC,  but (iii) any amount of
the  redemption  in  excess  of the  aggregate  of  the  then-current  value  of
Reinvested  Shares and the Free Amount is subject to a CDSC. The CDSC will first
be applied against the amount of Direct  Purchases which will result in any such
charge being imposed at the lowest  possible  rate.  The CDSC to be imposed upon
redemptions of shares will be calculated as set forth in "Purchases" above.

                                        -33-
<PAGE>

The  applicability  of a CDSC will be  unaffected  by  exchanges or transfers of
registration, except as described in Appendix A hereto.

GENERAL:  The following  information  applies to redemptions  and repurchases of
all classes of each Fund's shares.

         Signature  Guarantee.  In order to protect  shareholders against fraud,
each  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.

         Reinstatement Privilege. Shareholders of a 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 Class
C shares  and  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 SAI regarding this privilege.

         In-Kind  Distributions.  The Trust agrees to redeem shares of each Fund
solely in cash up to the lesser of  $250,000 or 1% of the net asset value of the
Fund during any 90-day  period for any one  shareholder.  Each Fund has reserved
the  right  to  pay  other  redemptions,  either  totally  or  partially,  by  a
distribution  in-kind of securities (instead of cash) from the Fund's portfolio.
The securities  distributed  in such a distribution  would be valued at the same
amount as that  assigned  to them in  calculating  the net  asset  value for the
shares  being  sold.  If a  shareholder  received a  distribution  in-kind,  the
shareholder  could incur  brokerage or transaction  charges when  converting the
securities to cash.

         Involuntary Redemptions/Small Accounts. Due to the relatively high cost
of maintaining small accounts,  each Fund reserves the right to redeem shares in
any account for their  then-current value if at any time the total investment in
such account drops below $500 because of redemptions or exchanges, except in the
case of accounts being established for monthly automatic investments and certain
payroll  savings  programs,  Automatic  Exchange Plan accounts and  tax-deferred
retirement plans, for which there is a lower minimum investment requirement. See
"Purchases - General - Minimum  Investment."  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.

DISTRIBUTION PLAN

The Trustees have adopted a  Distribution  Plan for Class A, Class B and Class C
shares pursuant to Section 12(b) of the 1940 Act and Rule 12b-1  thereunder (the
"Distribution  Plan"),  after  having  concluded  that  there  is  a  reasonable
likelihood that the Plan would benefit each Fund and its shareholders.

In certain  circumstances,  the fees  described  below may not be imposed or are
being waived. These circumstances, if any, are described below under the heading
"Current Level of Distribution and Service Fees."

FEATURES COMMON TO EACH CLASS OF SHARES:  There are features of the Distribution
Plan that are common to each Class of shares, as described below.

         Service Fees. The Distribution  Plan provides that a Fund may pay MFD a
service fee of up to 0.25% of the average daily net assets  attributable  to the
class of shares to which the Distribution  Plan relates (i.e.,  Class A, Class B
or Class C shares,  as appropriate)  (the "Designated  Class") annually in order
that MFD may pay  expenses on behalf of the Fund  relating to the  servicing  of
shares of the  Designated  Class.  The service fee is used by MFD to  compensate
dealers which enter into a sales  agreement  with MFD in  consideration  for all
personal  services and/or account  maintenance  services  rendered by the dealer
with respect to shares of the Designated  Class owned by investors for whom such
dealer is the dealer or holder of record.  MFD may from time to time  reduce the
amount of the service fees paid for shares sold prior to a certain date. Service
fees may be reduced  for a dealer  that is the holder or dealer of record for an
investor  who owns  shares of a Fund having an  aggregate  net asset value at or
above a certain dollar level.  Dealers may from time to time be required to meet
certain  criteria in order to receive  service fees.  MFD or its  affiliates are
entitled to retain all service  fees  payable  under the  Distribution  Plan for
which there is no dealer of record or for which qualification standards have not
been  met  as  partial   consideration  for  personal  services  and/or  account
maintenance services performed by MFD or its affiliates to shareholder accounts.

                                        -34-
<PAGE>

         Distribution  Fees. The Distribution  Plan provides that a Fund may pay
MFD a distribution  fee in addition to the service fee described  above based on
the average daily net assets  attributable  to the  Designated  Class as partial
consideration for distribution  services  performed and expenses incurred in the
performance of MFD's obligations under its distribution agreement with the Fund.
See  "Management  of the  Funds -  Distributor"  in the SAI.  The  amount of the
distribution  fee paid by a Fund with  respect to each class  differs  under the
Distribution  Plan,  as  does  the use by MFD of such  distribution  fees.  Such
amounts and uses are described  below in the discussion of the provisions of the
Distribution  Plan  relating  to each  Class of  shares.  While  the  amount  of
compensation  received by MFD in the form of  distribution  fees during any year
may be more or less than the  expenses  incurred  by MFD under its  distribution
agreement  with the Fund,  the Fund is not  liable to MFD for any losses MFD may
incur in performing services under its distribution agreement with the Fund.

         Other Common Features.  Fees payable under each  Distribution  Plan are
charged to, and therefore  reduce,  income allocated to shares of the Designated
Class.  The  provisions of the  Distribution  Plan are severable with respect to
each class of shares offered by the Fund.

FEATURES  UNIQUE  TO  CLASS  OF  SHARES:  There  are  certain  features  of  the
Distribution Plan that are unique to each class of shares, as described below.

         Class A Shares.  Class A shares are  generally  offered  pursuant to an
initial sales charge,  a substantial  portion of which is paid to or retained by
the  dealer  making  the sale  (the  remainder  of  which  is paid to MFD).  See
"Purchases - Class A Shares" above. In addition to the initial sales charge, the
dealer also  generally  receives  the ongoing  0.25% per annum  service  fee, as
discussed above.

   
         The distribution fee paid to MFD under the Distribution  Plan is equal,
on an  annual  basis,  to  0.25% of each the Core  Growth  Fund's,  the  Special
Opportunities  Fund's,  the Convertible  Securities Fund's, the Blue Chip Fund's
and the Science and Technology  Fund's average daily net assets  attributable to
Class A shares of each such  Fund,  and 0.10% of the  average  daily net  assets
attributable Class A shares of the Real Estate Fund. As noted above, MFD may use
the distribution fee to cover distribution-related expenses incurred by it under
its distribution  agreement with the Fund, including  commissions to dealers and
payments to wholesalers  employed by MFD (e.g.,  MFD pays commissions to dealers
with  respect  to  purchases  of $1  million  or more and  purchases  by certain
retirement  plans of Class A shares  which are sold at net asset value but which
are subject to a 1% CDSC for one year after purchase). Distribution fee payments
under  the  Distribution  Plan may be used by MFD to pay  securities  dealers  a
distribution  fee in an amount  equal to 0.25%  (0.10% for the Real Estate Fund)
per annum of each Fund's average daily net assets attributable to Class A shares
(other than Class A shares  that have  converted  from Class B shares)  owned by
investors  from whom that  securities  dealer is the holder or dealer of record.
See  "Purchases - Class A Shares"  above.  In  addition,  to the extent that the
aggregate service and distribution fees paid under the Class A Distribution Plan
do not exceed  0.50%  (0.35% for the Real Estate  Fund) per annum of the average
daily net assets of a Fund attributable to Class A shares, the Fund is permitted
to  pay  such  distribution-related   expenses  or  other   distribution-related
expenses.
    

         Class B Shares.  Class B shares are offered at net asset value  without
an initial sales charge but subject to a CDSC.  See "Purchases - Class B Shares"
above. MFD will advance to dealers the first year service fee described above at
a rate equal to 0.25% of the purchase price of such shares and, as  compensation
therefor,  MFD may retain the  service  fee paid by a Fund with  respect to such
shares  for the first year after  purchase.  Dealers  will  become  eligible  to
receive the  ongoing  0.25% per annum  service  fee with  respect to such shares
commencing in the thirteenth month following purchase.

         Under the Distribution  Plan, a Fund pays MFD a distribution fee equal,
on an annual basis, to 0.75% of the Fund's average daily net assets attributable
to Class B shares.  As noted above,  this distribution fee may be used by MFD to
cover its  distribution-related  expenses under its distribution  agreement with
the Fund  (including  the 3.75%  commission  it pays to dealers upon purchase of
Class B shares, as described under "Purchases - Class B Shares" above).

         Class C Shares.  Class C shares are offered at net asset value  without
an initial  sales charge but subject to a CDSC of 1.00% upon  redemption  during
the first year See "Purchases - Class C shares" above. MFD will pay a commission
to dealers of 1.00% of the purchase  price of Class C shares  purchased  through
dealers at the time of purchase.  In compensation for this 1.00% commission paid
by MFD to dealers,  MFD will retain the 1.00% per annum Class C distribution and
service  fees paid by the Fund with  respect  to such  shares for the first year
after purchase, and dealers will become eligible to receive from MFD the ongoing
1.00%  per  annum  distribution  and  service  fees paid by the Fund to MFD with
respect to such shares commencing in the thirteenth month following purchase.

                                        -35-
<PAGE>

         This ongoing  1.00% fee is comprised of the 0.25% per annum service fee
paid to MFD under the Distribution Plan (which MFD in turn pays to dealers),  as
discussed above, and a distribution fee paid to MFD (which MFD also in turn pays
to dealers) under the Distribution Plan equal, on an annual basis, to 0.75% of a
Fund's average daily net assets attributable to Class C shares.

CURRENT LEVEL OF DISTRIBUTION AND SERVICE FEES: Each Fund's Class A, Class B and
Class C  distribution  and service  fees for its current  fiscal year are 0.00%,
1.00% and 1.00%,  per annum,  respectively.  Distribution  and service  fees for
Class A shares  under the  Distribution  Plan are  currently  being  waived on a
voluntary basis and may be imposed at the discretion of MFD.

DISTRIBUTIONS

Each Fund intends to pay  substantially  all of its net investment income to its
shareholders as dividends at least  annually.  In determining the net investment
income  available for  distributions,  each Fund may rely on  projections of its
anticipated net investment income over a longer term, rather than its actual net
investment  income  for the  period.  If a Fund earns  less than  projected,  or
otherwise  distributes  more than its  earnings  for the year,  a portion of the
distributions may constitute a return of capital. Each 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 a 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

Each Fund is treated as an entity  separate  from the other  Funds and the other
series of the Trust for federal  income tax  purposes.  In order to minimize the
taxes each Fund would otherwise be required to pay, each Fund intends to qualify
each year as a "regulated  investment  company" under  Subchapter M of the Code.
Because each Fund intends to distribute all of its net investment income and net
realized  capital  gains to its  shareholders  in  accordance  with  the  timing
requirements  imposed  by the Code,  it is not  expected  that the Funds will be
required  to  pay  any  federal  income  or  excise  taxes,  although  a  Fund's
foreign-source income may be subject to foreign withholding taxes.

Shareholders  of a 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 reinvested in additional shares.
A portion of the dividends  received from a Fund (but none of the Funds' capital
gains  distributions)  may  qualify  for the  dividends-received  deduction  for
corporations.  Shortly after the end of each year,  each  shareholder  of a Fund
will be sent a  statement  setting  forth the  federal  income tax status of all
dividends and  distributions  for that year,  including  the portion  taxable as
ordinary income,  the portion taxable as long-term  capital gain (as well as the
rate category or categories under which such gain is taxable),  the portion,  if
any,  representing a return of capital (which is generally free of current taxes
but results in a basis reduction) and the amount,  if any, of federal income tax
withheld.

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

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

NET ASSET VALUE

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

                                        -36-
<PAGE>

described in the SAI. All investments  and assets are expressed in U.S.  dollars
based upon current  currency  exchange  rates.  The net asset value per share of
each class of shares is  effective  for orders  received in "good  order" by the
dealer prior to its calculation and received by the dealer prior to the close of
that business day.

EXPENSES

   
The Trust pays the  compensation of the Trustees who are not officers of MFS and
all expenses of the Funds (other than those  assumed by MFS)  including  but not
limited to: advisory and administrative  services;  governmental fees;  interest
charges; taxes; membership dues in the Investment Company Institute allocable to
the Funds; fees and expenses of independent  auditors,  of legal counsel, and of
any  transfer  agent,  registrar  or  dividend  disbursing  agent of the  Funds;
expenses  of  repurchasing  and  redeeming  shares  and  servicing   shareholder
accounts;  expenses of preparing,  printing and mailing  prospectuses,  periodic
reports,  notices  and proxy  statements  to  shareholders  and to  governmental
officers  and  commissions;  brokerage  and other  expenses  connected  with the
execution,   recording  and  settlement  of  portfolio  security   transactions;
insurance  premiums;  fees and expenses of State Street Bank and Trust  Company,
the Funds' custodian,  for all services to the Funds,  including  safekeeping of
funds and securities and  maintaining  required books and accounts;  expenses of
calculating  the net  asset  value of  shares  of the  Funds;  and  expenses  of
shareholder  meetings.  Expenses  relating  to the  issuance,  registration  and
qualification of shares of the Funds and the  preparation,  printing and mailing
of prospectuses  are borne by the Funds except that the  Distribution  Agreement
with MFD  requires  MFD to pay for  prospectuses  that are to be used for  sales
purposes.  Expenses of the Trust which are not attributable to a specific series
are allocated between the series in a manner believed by management of the Trust
to be fair and equitable.

         Subject to termination  or revision at the sole  discretion of MFS, MFS
has agreed to bear the  expenses  (after  taking  into  effect any  compensating
balance and offset  arrangements) of the Funds such that each such Fund's "Other
Expenses,"  which are defined to include all Fund expenses except for management
fees, Rule 12b-1 fees, taxes, extraordinary expenses,  brokerage and transaction
costs and class specific expenses, do not exceed 1.50% for the Core Growth Fund,
the Special  Opportunities Fund, the Convertible  Securities Fund, the Blue Chip
Fund and the Science and Technology Fund and 1.65% for the Real Estate Fund, per
annum, of its average daily net assets (the "Maximum Percentage").  The payments
made by MFS on behalf of these  Funds  under  this  arrangement  are  subject to
reimbursement  by such Fund to MFS, which will be accomplished by the payment of
an expense  reimbursement  fee by the Fund to MFS computed and paid monthly at a
percentage  of its average  daily net assets for its then  current  fiscal year,
with a  limitation  that  immediately  after such  payment  such  Fund's  "Other
Expenses" will not exceed the Maximum Percentage.  The obligation of MFS to bear
each  Fund's  "Other  Expenses"  pursuant to this  arrangement,  and each Fund's
obligation to pay the reimbursement fee to MFS, terminates on the earlier of the
date on  which  payments  made by the  Fund  equal  the  prior  payment  of such
reimbursable  expenses by MFS or August 31, 2006,  for the Core Growth Fund, the
Special Opportunities Fund, the Convertible  Securities Fund, the Blue Chip Fund
and the Science and Technology Fund and July 31, 2002, for the Real Estate Fund.
    

DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES

   
Each Fund has three  classes of shares  which it offers to the  general  public,
entitled Class A, Class B and Class C shares of Beneficial Interest (without par
value).  Each  Fund also has a class of shares  which it offers  exclusively  to
certain institutional investors, entitled Class I shares. As of the date of this
Prospectus,  the Trust has fourteen series of shares. The Trust has reserved the
right to create and issue additional classes and series of shares, in which case
each class of shares of a series  would  participate  equally  in the  earnings,
dividends  and  assets  attributable  to that class of that  particular  series.
Shareholders  are  entitled  to one vote for each  share held and shares of each
series  would be  entitled to vote  separately  to approve  investment  advisory
agreements or changes in investment restrictions, but shares of all series would
vote  together  in the  election  of  Trustees  and  selection  of  accountants.
Additionally,  each  class of shares of a series  will  vote  separately  on any
material  increases  in the fees  under  the  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  Trust's
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 SAI).
    

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

The Trust is an entity of the type commonly known as a  "Massachusetts  business
trust." Under Massachusetts law, shareholders of such a trust may, under certain
circumstances,  be held  personally  liable  as  partners  for its  obligations.
However,  the risk of a  

                                        -37-
<PAGE>

shareholder  incurring financial loss on account of shareholder  liability would
be limited to circumstances in which both inadequate  insurance  existed and the
Trust itself was unable to meet its obligations.

PERFORMANCE INFORMATION

From time to time, each Fund may 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 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 a 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 and Class C 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 a 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 and Class C shares assumes 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 a Fund  made at the  maximum  public  offering  price of the
shares of that  class  with all

                                        -38-
<PAGE>
   
distributions  reinvested  and which will give effect to the  imposition  of any
applicable  CDSC  assessed  upon  redemptions  of the Fund's Class B and Class C
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.  Each
Fund offers multiple classes of shares which were initially offered for sale to,
and purchased by, the public on different  dates (the class  "inception  date").
The  calculation of total rate of return for a class of shares which has a later
class inception date than another class of shares of a Fund is based both on (i)
the  performance  of the Fund's newer class from its inception date and (ii) the
performance  of the Fund's oldest class from its inception  date up to the class
inception  date of the newer class.  See the SAI for further  information on the
calculation  of total  rate of return for share  classes  with  different  class
inception dates.
    

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 a Fund over a stated  period of time,  while
total rate of return reflects all components of investment  return over a stated
period  of  time.  A  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 a Fund will  calculate  its yield,  current
distribution rate and total rate of return, see the SAI. For further information
about the Funds'  performance for the fiscal year ended August 31, 1997,  please
see the Funds' annual report. A copy of the Funds' Annual Report may be obtained
without charge by contacting the Shareholder Servicing Agent (see back cover for
address and phone number).  In addition to  information  provided in shareholder
reports, each 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.

9.       SHAREHOLDER SERVICES

Shareholders with questions  concerning the shareholder services described below
or concerning other aspects of a Fund, should contact the Shareholder  Servicing
Agent (see back cover for address and phone number).  A shareholder whose shares
are held in the name of, or  controlled  by, a dealer  might not receive many of
the privileges and services from a Fund (such as Right of  Accumulation,  Letter
of Intent and certain recordkeeping services) that a Fund ordinarily provides.

Account  and   Confirmation   Statements  --  Each   shareholder   will  receive
confirmation  statements showing the transaction activity in his account. At the
end of each calendar year, each shareholder will receive  information  regarding
the tax status of reportable dividends and distributions for that year (see "Tax
Status").

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

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

         --   Dividends  (including  short-term  capital gains) in cash; capital
              gain distributions reinvested in additional shares; or

         --   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 such  Fund.  If a  shareholder  has  elected  to  receive
dividends  and/or  capital gain  distributions  in cash, and the postal or other
delivery  service is unable to deliver  checks to the  shareholder's  address of
record,  or the  shareholder  does not respond to mailings from the  Shareholder
Servicing Agent with regard to uncashed  distribution checks, such shareholder's
distribution  option will automatically be converted to having all dividends and
other  distributions  reinvested in additional  shares.  Any request to change a
distribution  option must be received by the Shareholder  Servicing Agent by the
record date for a dividend or  distribution  in order to be  effective  for that
dividend or  distribution.  No interest  will accrue on amounts  represented  by
uncashed distribution or redemption checks.
    

Investment and Withdrawal Programs -- For the convenience of shareholders,  each
Fund makes available the following  programs designed to enable  shareholders to
add to their  investment  in an account  with a 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 a Fund.

         Letter of Intent:  If a  shareholder  (other than a group  purchaser as
described in the SAI) anticipates  purchasing $100,000 or more of Class A shares
of a Fund alone or in combination  with shares of Class B or Class C shares of a
Fund  or any of the  classes  of  

                                        -39-
<PAGE>

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

         Right of Accumulation:  A shareholder qualifies for cumulative quantity
discounts on purchases of Class A shares when his new investment,  together with
the current offering price value of all holdings of Class A, Class B and Class C
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 a Fund
may be sold at net asset value (and  without any  applicable  CDSC)  through the
automatic  reinvestment of dividend and capital gain distributions from the same
class of  another  MFS Fund.  Furthermore,  distributions  made by a Fund may be
automatically invested at net asset value in shares of the same class of another
MFS Fund,  if shares of such Fund are available for sale (without a sales charge
and not subject to any applicable CDSC).

         Systematic  Withdrawal  Plan: A shareholder  may direct the Shareholder
Servicing  Agent  to send to him (or  any one he  designates)  regular  periodic
payments  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 and Class C 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 CDSC.

Dollar Cost Averaging Programs --

         Automatic  Investment Plan: Cash investments of $50 or more may be made
through  a  shareholder's  checking  account  on any  day of the  month.  If the
shareholder does not specify a date, the investment will automatically  occur on
the first  business  day of the month.  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  participate in the Automatic  Exchange Plan, a
dollar  cost  averaging  program.  The  Automatic  Exchange  Plan  provides  for
automatic monthly or quarterly exchanges of funds from the shareholder's account
in an MFS Fund for  investment  in the same  class of  shares of other MFS Funds
selected  by the  shareholder  (if  available  for  sale).  Under the  Automatic
Exchange Plan, exchanges of at least $50 each may be made to up to six different
funds. A shareholder  should  consider the objectives and policies of a fund and
review its prospectus  before  electing to exchange money into such fund through
the Automatic  Exchange Plan. No transaction  fee is imposed in connection  with
exchange  transactions under the Automatic Exchange Plan. However,  exchanges of
shares of MFS Money Market  Fund,  MFS  Government  Money Market Fund or Class A
shares of MFS Cash Reserve Fund will be subject to any applicable  sales charge.
For federal and (generally) state income tax purposes, an exchange is treated as
a sale of the shares transferred and, therefore,  could result in a capital gain
or  loss to the  shareholder  making  the  exchange.  See  the  SAI 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 an investment program concurrently with a withdrawal program
would  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 share redemption (if applicable) in the case of Class A shares.

Tax-Deferred  Retirement  Plans -- Except as noted under  "Purchases  -- Class C
Shares" above, shares of each Fund may be purchased by all types of tax-deferred
retirement  plans,  including IRAs,  Simplified  Employee Pension plans,  401(k)
plans,  403(b)  plans and other  corporate  pension  and  profit-sharing  plans.
Investors should consult with their tax advisers before  establishing any of the
tax-deferred retirement plans described above.

                                                                   APPENDIX B

                          DESCRIPTION OF BOND RATINGS

                                    MOODY'S

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

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

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

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

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

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

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

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

         C: Bonds  which are rated C are the lowest  rated  class of bonds,  and
issues so rated can be  regarded  as having  extremely  poor  prospects  of ever
attaining  any  real  investment  standing.   Note:  Moody's  applies  numerical
modifiers,  1, 2 and 3 in each generic rating  classification  from Aa to B. The
modifier 1  indicates  that the  company  ranks in the higher end of its generic
rating category;  the modifier 2 indicates a mid-range ranking; and the modifier
3  indicates  that the  company  ranks in the  lower end of its  generic  rating
category.

                                      S&P
   
         AAA:  An  obligation  rated  AAA has the  highest  rating  assigned  by
S&P.  The  obligor's   capacity  to  meet  its   financial   commitment  on  the
obligation is EXTREMELY STRONG.

         AA: An obligation rated AA differs from the higher rated issues only in
small  degree.  The obligor's  capacity to meet its financial  commitment on the
obligation is VERY STRONG.

         A: An obligation  rated A is somewhat more  susceptible  to the adverse
effects of changes in circumstances and economic  conditions than obligations in
higher rated  categories.  However the obligor's  capacity to meet its financial
commitment on the obligation is still STRONG.

         BBB: An obligation rated BBB exhibits ADEQUATE  protection  parameters.
However,  adverse economic conditions or changing  circumstances are more likely
to lead to a weakened  capacity of the obligor to meet its financial  commitment
on the obligation.

         Obligations  rated  BB,  B,  CCC,  CC  and C  are  regarded  as  having
significant  speculative  characteristics.  BB  indicates  the  least  degree of
speculation  and C the  highest.  While such  obligations  will likely have some
quality  and  protective  characteristics,  these  may be  outweighed  by  large
uncertainties or major exposures to adverse conditions.

         BB: An obligation  rated BB is LESS VULNERABLE to nonpayment than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse  business,  financial,  or economic  conditions  which could lead to the
obligor's   inadequate  capacity  to  meet  its  financial   commitment  on  the
obligation.

         B:  An  obligation  rated  B is  MORE  VULNERABLE  to  nonpayment  than
obligations  rated BB, but the obligor

                                        -1-
    
<PAGE>
   
currently has the capacity to meet its financial  commitment on the  obligation.
Adverse  business,  financial,  or economic  conditions  will likely  impair the
obligor's  capacity  or  willingness  to meet its  financial  commitment  on the
obligation.

         CCC: An obligation rated CCC is CURRENTLY VULNERABLE to nonpayment, and
is dependent upon favorable business, financial, and economic conditions to meet
its financial  commitment on the obligation.  In the event of adverse  business,
financial,  or  economic  conditions,  the  obligor  is not  likely  to have the
capacity to meet its financial commitment on the obligation.

         CC:  An  obligation  rated  CC  is  CURRENTLY   HIGHLY   VULNERABLE  to
nonpayment.

         C: The C rating  may be used to cover a  situation  where a  bankruptcy
petition has been filed or similar  action has been taken,  but payments on this
obligation are being continued.

         D: An obligation rated D is in payment  default.  The D rating category
is used when payments on an obligation  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 or the taking of similar actions of payments on
an obligation 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  major
categories.

         r:  This  symbol  is  attached  to  the  ratings  of  instruments  with
significant  noncredit  risks. It highlights risks to principal or volatility of
expected returns which are not addressed in the credit rating. Examples include:
obligations  linked  or  indexed  to  equities,   currencies,   or  commodities;
obligations  exposed  to  severe  prepayment  risks--such  as  interest-only  or
principal-only  mortgage  securities;   and  obligations  with  unusually  risky
interest terms, such as inverse floaters.

                                     FITCH

         AAA: Highest credit quality.  AAA ratings denote the lowest expectation
of credit risk. They are assigned only in case of exceptionally  strong capacity
for timely payment of financial commitments. This capacity is highly unlikely to
be adversely affected by foreseeable events.

         AA:  Very  high  credit   quality.   AA  ratings   denote  a  very  low
expectation  of credit  risk.  They  indicate  very strong  capacity  for timely
payment  of  financial   commitments.   This   capacity  is  not   significantly
vulnerable to foreseeable events.

         A: High credit  quality.  A ratings denote a low  expectation of credit
risk.  The capacity for timely  payment of financial  commitments  is considered
strong.  This  capacity  may,  nevertheless,  be more  vulnerable  to changes in
circumstances or in economic conditions than is the case for higher ratings.

         BBB: Good credit quality.  BBB ratings indicate that there is currently
a low  expectation  of credit risk. The capacity for timely payment of financial
commitments is considered adequate,  but adverse changes in circumstances and in
economic conditions are more likely to impair this capacity.  This is the lowest
investment-grade category.

         BB:  Speculative.  BB ratings  indicate that there is a possibility  of
credit risk  developing,  particularly as the result of adverse  economic change
over time;  however,  business or  financial  alternatives  may be  available to
allow  financial  commitments to be met.  Securities  rated in this category are
not investment grade.

         B: Highly speculative.  B ratings indicate that significant credit risk
is present,  but a limited margin of safety remains.  Financial  commitments are
currently being met; however,  capacity for continued payment is contingent upon
a sustained, favorable business and economic environment.

         CCC, CC, C: High default risk. Default is a real possibility.  Capacity
for meeting  financial  commitments is solely reliant upon sustained,  favorable
business or economic  developments.  A CC rating  indicates that default of some
kind appears probable. C ratings signal imminent default.

         DDD,  DD  and  D:   Default.   Securities   are  not  meeting   current
obligations   and  are  extremely   speculative.   DDD  designates  the  highest
potential for recovery of amounts  outstanding on any securities  involved.  For
U.S.  corporates,  for example,  DD indicates  expected  recovery of 50%--90% of
such outstandings, and D the lowest recovery potential, i.e., below 50%.

                                 DUFF & PHELPS

         These  ratings  represent a summary  opinion of the issuer's  long-term
fundamental   quality.   Rating   determination  is  based  on  qualitative  and
quantitative  factors  which  may  vary  according  to the  basic  economic  and
financial   characteristics   of  each  industry  and  each  issuer.   Important
considerations  are vulnerability to economic cycles as well as risks related to
such  factors  as  competition,  government  action,  regulation,  technological
obsolescence, demand shifts, cost structure, and management depth and expertise.
The projected  viability of the obligor at the trough of the cycle is a critical
determination.

                                        B-2

         Each  rating  also takes into  account  the legal form of the  security
(e.g.,  first mortgage bonds,  subordinated  debt,  preferred stock,  etc.). The
extent  of  rating  dispersion  among  the  various  classes  of  securities  is
determined  by several  classes in the capital  structure,  the  overall  credit
strength of the  issuer,  and the nature of  covenant  protection.  From time to
time,  Duff & Phelps places  issuers or security  classes on Rating  Watch.  The
Rating Watch status results from a need to notify  investors and the issuer that
there are conditions present leading us to re-evaluate the current rating(s).

         A listing on Rating  Watch,  however,  does not mean a rating change is
inevitable.  The Rating  Watch  status can either be resolved  quickly or over a
longer  period of time  depending on the reasons  surrounding  the  placement on
Rating Watch.  The "up" designation  means a rating may be upgraded;  the "down"
designation  means a rating may be downgraded,  and the "uncertain"  designation
means a rating may be raised or lowered.

         The Credit  Rating  Committee  formally  reviews all  ratings  once per
quarter (more frequently, if necessary).  Ratings of BBB- and higher fall within
the definition of investment grade securities,  as defined by bank and insurance
supervisory  authorities.  Structured  finance  issues,  including  real estate,
asset-backed and mortgage-backed financings, used this same rating scale. Duff &
Phelps claims paying ability  ratings of insurance  companies use the same scale
with minor  modification in the  definitions.  Thus, an investor can compare the
credit  quality of investment  alternatives  across  industries  and  structural
types.  A "Cash Flow  Rating"  (as noted for  specific  ratings)  addresses  the
likelihood that aggregate  principal and interest will equal or exceed the rated
amount under appropriate stress conditions.

         AAA:  Highest credit quality.  The risk factors are  negligible,  being
only slightly more than for risk-free U.S. Treasury debt.

         AA+, AA, AA-: High credit quality.  Protection factors are strong. Risk
is  modest  but  may  vary  slightly  from  time  to time  because  of  economic
conditions.

         A+, A, A-: Protection factors are average but adequate.  However,  risk
factors are more variable and greater in periods of economic stress.

         BBB+, BBB, BBB-: Below average  protection factors but still considered
sufficient  for  prudent  investment.  Considerable  variability  in risk during
economic cycles.

         BB+,  BB,  BB-:  Below  investment  grade  but  deemed  likely  to meet
obligations  when due.  Present  or  prospective  financial  protection  factors
fluctuate according to industry conditions or company fortunes.  Overall quality
may move up or down frequently within this category.

         B+, B, B-: Below  investment grade and possessing risk that obligations
will not be met when due.  Financial  protection  factors will fluctuate  widely
according to economic  cycles,  industry  conditions  and/or  company  fortunes.
Potential exists for frequent changes in the rating within this category or into
a higher or lower rating grade.

         CCC: Well below investment grade securities.  Considerable  uncertainty
exists as to timely  payment of  principal,  interest  or  preferred  dividends.
Protection  factors  are narrow  and risk can be  substantial  with  unfavorable
economic/industry conditions, and/or with unfavorable company developments.

         DD:  Defaulted  debt  obligations.  Issuers  failed  to meet  scheduled
principal and/or interest payments.

         DP:  Preferred stock with dividend arrearages.

ELIGIBLE PURCHASERS

Class I shares are  available  for  purchase  only by the  following  purchasers
("Eligible Purchasers"):

(i)  certain  retirement  plans  established  for the  benefit of  employees  of
     Massachusetts Financial Services Company ("MFS"), the Fund's investment
     adviser, and employees of MFS' affiliates; and

(ii) any fund distributed by MFS Fund  Distributors,  Inc.  ("MFD"),  the Fund's
     distributor,  if the fund  seeks to achieve  its  investment  objective  by
     investing  primarily in shares of the Fund and other funds  distributed  by
     MFD.

         In no event will the Fund, MFS, MFD or any of their  affiliates pay any
sales commissions or compensation to any third party in connection with the sale
of Class I shares;  the  payment of any such sales  commission  or  compensation
would,  under the Fund's  policies,  disqualify  the  purchaser  as an  eligible
investor of Class I shares.

SHARE CLASSES OFFERED BY THE FUNDS

   
         While each Fund has four  classes of shares  (Class A, Class B, Class C
and Class I shares),  Class A and Class I shares are the only classes  presently
available  for sale.  Class I shares are available for purchase only by Eligible
Purchasers,  as defined  above,  and are described in this  Supplement.  Class A
shares,  Class  B  shares  and  Class  C  shares  are  described  in the  Funds'
Prospectus.  Class A shares are  available  for purchase by employees of MFS and
its  affiliates  and certain of their  family  members who are  residents of The
Commonwealth  of  Massachusetts,  and  members  of the  governing  boards of the
various funds sponsored by MFS.

         Class A shares  are  offered at net asset  value plus an initial  sales
charge up to a maximum of 4.75% of the  offering  price of the Core Growth Fund,
Special  Opportunities  Fund,  Convertible  Securities  Fund, Blue Chip Fund and
Science and  Technology  Fund or 5.75% of the offering  price of the Real Estate
Fund (or a contingent  deferred sales charge (a "CDSC") of 1.00% upon redemption
during the first year in the case of purchases of $1 million or more and certain
purchases by retirement  plans),  and are subject to an annual  distribution fee
and  service  fee up to a maximum of 0.50% per annum  (0.35% for the Real Estate
Fund).  Class B shares are offered at net asset value  without an initial  sales
charge but are subject to a CDSC upon  redemption  (declining  from 4.00% during
the first year to 0% after six years) and an annual distribution fee and service
fee up to a maximum of 1.00% per annum; Class B shares convert to Class A shares
approximately  eight  years  after  purchase.  Class C shares are offered at net
asset value  without an initial  sales charge but are subject to a CDSC of 1.00%
upon redemption during the first year and an annual distribution fee and service
fee up to a maximum of 1.00% per annum.  Class I shares are offered at net asset
value  without  an  initial  sales  charge  or CDSC  and are  not  subject  to a
distribution  or service  fee.  Class C and Class I shares do not convert to any
other class of shares of the Funds.
    

OTHER INFORMATION

         Eligible  Purchasers may purchase Class I shares only directly  through
MFD.  Eligible  Purchasers  may  exchange  Class I shares  of a Fund for Class I
shares of any other MFS Fund available for purchase by such Eligible  Purchasers
at their net asset  value (if  available  for sale),  and may  exchange  Class I
shares of a Fund for  shares  of the MFS Money  Market  Fund (if  available  for
sale), and may redeem Class I shares of a Fund at net asset value. Distributions
paid by a Fund with  respect to Class I shares  generally  will be greater  than
those 

                                        -6-

paid with respect to Class A shares,  Class B shares and Class C shares  because
expenses  attributable  to Class A  shares,  Class B shares  and  Class C shares
generally will be higher.

   
         Subject to termination  or revision at the sole  discretion of MFS, MFS
has agreed to bear the  expenses  (after  taking  into  effect any  compensating
balance and offset  arrangements) of the Funds such that each such Fund's "Other
Expenses,"  which are defined to include all Fund expenses except for management
fees, Rule 12b-1 fees, taxes, extraordinary expenses,  brokerage and transaction
costs and class specific expenses, do not exceed 1.50% for the Core Growth Fund,
Special  Opportunities  Fund,  Convertible  Securities  Fund, Blue Chip Fund and
Science and Technology  Fund, and 1.65% for the Real Estate Fund, per annum,  of
its average  daily net assets (the "Maximum  Percentage").  The payments made by
MFS on behalf of these Funds under this arrangement are subject to reimbursement
by such Fund to MFS,  which will be  accomplished  by the  payment of an expense
reimbursement  fee by the Fund to MFS  computed and paid monthly at a percentage
of its  average  daily net  assets  for its then  current  fiscal  year,  with a
limitation that immediately after such payment such Fund's "Other Expenses" will
not exceed the Maximum  Percentage.  The  obligation  of MFS to bear each Fund's
"Other Expenses" pursuant to this arrangement, and each Fund's obligation to pay
the  reimbursement  fee to MFS,  terminates  on the earlier of the date on which
payments made by the Fund equal the prior payment of such reimbursable  expenses
by MFS or August 31, 2006, for the Core Growth Fund, Special Opportunities Fund,
Convertible Securities Fund, Blue Chip Fund and Science and Technology Fund, and
July 31, 2002, for the Real Estate Fund.

2.       INVESTMENT OBJECTIVES, POLICIES AND RESTRICTIONS

Investment  Objectives and Policies.  The  investment  objective and policies of
each Fund are described in the Prospectus and below. The following discussion of
each Fund's investment  techniques and restrictions  supplements,  and should be
read  in  conjunction  with,  the  information  set  forth  in  the  "Investment
Objectives and Policies,"  "Certain  Securities and Investment  Techniques"  and
"Additional Risk Factors" sections of the Prospectus.

Certain Securities and Investment Techniques.

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

Repurchase  Agreements:  Each Fund may enter  into  repurchase  agreements  with
sellers  who are member  firms (or a  subsidiary  thereof)  of the  Exchange  or
members of the  Federal  Reserve  System,  recognized  primary  U.S.  Government
securities  dealers or  institutions  which the Adviser has  determined to be of
comparable  creditworthiness.  The  securities  that a Fund  purchases and 

                                        1
<PAGE>
holds through its agent are U.S. Government securities,  the values of which are
equal to or greater than the  repurchase  price agreed to be paid by the seller.
The repurchase price may be higher than the purchase price, the difference being
income to the Fund, or the purchase and repurchase  prices may be the same, with
interest at a standard rate due to the Fund together with the  repurchase  price
on  repurchase.  In either  case,  the  income to the Fund is  unrelated  to the
interest rate on the Government securities.

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

"When-Issued"  Securities:  Each Fund may purchase securities on a "when-issued"
or on a  "forward  delivery"  basis.  When  a Fund  commits  to  purchase  these
securities  on a  "when-issued"  or  "forward  delivery"  basis,  it will set up
procedures consistent with the General Statement of Policy of the Securities and
Exchange  Commission (the "SEC")  concerning  such purchases.  Since that policy
currently recommends that an amount of each Fund's assets equal to the amount of
the purchase be held aside or segregated to be used to pay for the commitment, a
Fund will always have liquid assets  sufficient to cover any  commitments  or to
limit any potential  risk.  Although no Fund intends to make such  purchases for
speculative  purposes and intends to adhere to the provisions of the SEC policy,
purchases of  securities on such bases may involve more risk than other types of
purchases. For example, a Fund may have to sell assets which have been set aside
in order to meet redemptions. Also, if a Fund determines it is necessary to sell
the "when-issued" or "forward delivery" securities before delivery, it may incur
a loss because of market  fluctuations since the time the commitment to purchase
such securities was made.

Foreign  Securities:   Each  Fund  may  invest  in  dollar-denominated  and  non
dollar-denominated foreign securities. As discussed in the Prospectus, investing
in  foreign  securities  generally  represents  a  greater  degree  of risk than
investing in domestic  securities  due to possible  exchange rate  fluctuations,
less publicly  available  information,  more volatile  markets,  less securities
regulation, less favorable tax provisions, war or expropriation.  As a result of
its investments in foreign  securities,  a Fund may receive interest or dividend
payments,  or the proceeds of the sale or redemption of such securities,  in the
foreign  currencies  in which such  securities  are  denominated.  Under certain
circumstances,  such as where the Adviser believes that the applicable  exchange
rate is  unfavorable  at the time the  currencies  are  received  or the Adviser
anticipates,  for any other reason,  that the exchange rate will improve, a Fund
may hold such currencies for an indefinite  period of time. While the holding of
currencies will permit the Fund to take advantage of favorable  movements in the
applicable exchange rate, such strategy also exposes the Fund to risk of loss if
exchange rates move in a direction  adverse to the Fund's position.  Such losses
could reduce any profits or increase  any losses  sustained by the Fund from the
sale or redemption  of securities  and could reduce the dollar value of interest
or dividend payments received.

American  Depositary  Receipts:  Each  Fund may  invest in  American  Depositary
Receipts ("ADRs") which are certificates  issued by a U.S. depository (usually a
bank) and  represent a specified  quantity of shares of an  underlying  non-U.S.
stock on deposit with a custodian bank as  collateral.  ADRs may be sponsored or
unsponsored.  A sponsored  ADR is issued by a depository  which has an exclusive
relationship with the issuer of the underlying security.  An unsponsored ADR may
be issued by any number of U.S. depositories.  Under the terms of most sponsored
arrangements,  depositories agree to distribute notices of shareholder  meetings
and voting  instructions,  and to provide  shareholder  communications and other
information  to the ADR  holders at the  request of the issuer of the  deposited
securities. The depository of an unsponsored ADR, on the other hand, is under no
obligation to distribute shareholder  communications received from the issuer of
the  deposited  securities  or to pass through  voting  rights to ADR holders in
respect of the deposited securities. Each Fund may invest in either type of ADR.
Although the U.S.  investor holds a substitute  receipt of ownership rather than
direct stock  certificates,  the use of the depository  receipts in the U.S. can
reduce  costs  and  delays  as well as  potential  currency  exchange  and other
difficulties.  Each Fund may  purchase  securities  in local  markets and direct
delivery of these ordinary  shares to the local  depository of an ADR agent bank
in the foreign  country.  Simultaneously,  the ADR agents  create a  certificate
which settles at the Fund's  custodian in five days.  Each Fund may also execute
trades on the U.S. markets using existing ADRs. A foreign issuer of the security
underlying an ADR is generally not subject to the same 

                                        2
<PAGE>
reporting  requirements  in the  U.S.  as a  domestic  issuer.  Accordingly  the
information  available to a U.S. investor will be limited to the information the
foreign  issuer is required to disclose in its own country and the market  value
of an ADR may not reflect undisclosed material information concerning the issuer
of the underlying  security.  ADRs may also be subject to exchange rate risks if
the underlying foreign securities are denominated in foreign currency.

   
Mortgage  "Dollar  Roll"  Transactions:  The  Special  Opportunities  Fund,  the
Convertible  Securities  Fund and the Real Estate  Fund may enter into  mortgage
"dollar roll" transactions pursuant to which it sells mortgage-backed securities
for  delivery  in  the  future  and   simultaneously   contracts  to  repurchase
substantially  similar  securities on a specified  future date. The Funds record
these transactions as sale and purchase  transactions,  rather than as borrowing
transactions.  During the roll period,  a Fund  foregoes  principal and interest
paid on the  mortgage-backed  securities.  Each Fund is compensated for the lost
interest by the  difference  between the current sales price and the lower price
for the future  purchase  (often  referred  to as the  "drop") as well as by the
interest  earned on the cash proceeds of the initial sale. Each Fund may also be
compensated  by receipt of a  commitment  fee.  In the event that the party with
whom the Fund contracts to replace  substantially similar securities on a future
date fails to deliver such  securities,  the Fund may not be able to obtain such
securities at the price specified in such contract and thus may not benefit from
the price differential between the current sales price and the repurchase price.

Corporate   Asset-Backed   Securities:   The  Special  Opportunities  Fund,  the
Convertible  Securities  Fund and the Real Estate  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 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. Each 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.

   
Collateralized Mortgage Obligations and Multiclass Pass-Through Securities:  The
Special Opportunities Fund, the Convertible  Securities Fund and the Real Estate
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 (such collateral  referred to collectively as
"Mortgage  Assets").  Unless the context  indicates  otherwise,  all  references
herein to CMOs include multiclass pass-through securities.
    

Interest is paid or accrues on all  classes of the CMOs on a monthly,  quarterly
or semi-annual  basis.  The principal of and interest on the Mortgage Assets may
be allocated among the several classes of a CMO in innumerable ways. In a common
structure,  payments of principal,  including any principal prepayments,  on the
Mortgage  Assets  are  applied  to the  classes  of a CMO in the  order of their
respective stated maturities or final distribution  dates, so that no payment of
principal  will be made on any class of CMOs until all other  classes  having an
earlier  stated  maturity  or final  distribution  date  have been paid in full.
Certain CMOs may be stripped  (securities  which  provide only the  principal or
interest  factor of the  underlying  security).  See  "Stripped  Mortgage-Backed
Securities"  below for a discussion of the risks of investing in these  

                                        3
<PAGE>
stripped  securities and of investing in classes consisting of interest payments
or principal payments.

Each of the Special  Opportunities Fund and the Convertible  Securities Fund may
also invest in  parallel  pay CMOs and  Planned  Amortization  Class CMOs ("'PAC
Bonds").  Parallel pay CMOs are  structured to provide  payments of principal on
each payment date to more than one class. These simultaneous  payments are taken
into account in calculating the stated maturity date or final  distribution date
of each  class,  which,  as with  other CMO  structures,  must be retired by its
stated maturity date or final distribution date but may be retired earlier.

   
Stripped  Mortgage-Backed   Securities:  The  Special  Opportunities  Fund,  the
Convertible Securities Fund and the Real Estate Fund may invest a portion of its
assets in stripped  mortgage-backed  securities  ("SMBS")  which are  derivative
multiclass  mortgage securities issued by agencies or  instrumentalities  of the
U.S. Government,  or by private originators of, or investors in, mortgage loans,
including savings and loan  institutions,  mortgage banks,  commercial banks and
investment banks.
    

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

   
Loans and  Other  Direct  Indebtedness:  The  Special  Opportunities  Fund,  the
Convertible  Securities  Fund and the Real  Estate Fund may  purchase  loans and
other direct indebtedness.  In purchasing a loan, a Fund acquires some or all of
the interest of a bank or other  lending  institution  in a loan to a corporate,
governmental or other borrower.  Many such loans are secured,  although some may
be unsecured.  Such loans may be in default at the time of purchase.  Loans that
are fully secured  offer a Fund more  protection  than an unsecured  loan in the
event of non-payment of scheduled  interest or principal.  However,  there is no
assurance that the  liquidation of collateral  from a secured loan would satisfy
the corporate borrower's obligation, or that the collateral can be liquidated.
    

These  loans  are  made   generally  to  finance   internal   growth,   mergers,
acquisitions,   stock  repurchases,   leveraged  buy-outs  and  other  corporate
activities.   Such  loans  are   typically   made  by  a  syndicate  of  lending
institutions,  represented by an agent lending  institution which has negotiated
and structured the loan and is responsible  for collecting  interest,  principal
and other  amounts  due on its own  behalf  and on  behalf of the  others in the
syndicate,  and for enforcing  its and their other rights  against the borrower.
Alternatively,  such loans may be structured as a novation,  pursuant to which a
Fund would assume all of the rights of the lending  institution  in a loan or as
an  assignment,  pursuant to which the Fund would  purchase an  assignment  of a
portion of a lender's  interest  in a loan  either  directly  from the lender or
through an intermediary.  A Fund may also purchase trade or other claims against
companies, which generally represent money owned by the company to a supplier of
goods or services. These claims may also be purchased at a time when the company
is in default.

Certain of the loans and the other  direct  indebtedness  acquired by a Fund may
involve revolving credit facilities or other standby financing commitments which
obligate the Fund to pay additional  cash on a certain date or on demand.  These
commitments  may have the effect of requiring a Fund to increase its  investment
in a  company  at a time  when the Fund  might  not  otherwise  decide  to do so
(including at a time when the company's  financial  condition  makes it unlikely
that such  amounts  will be repaid).  To the extent that a Fund is  committed to
advance additional funds, it will at all times hold and maintain in a segregated
account liquid assets in an amount sufficient to meet such commitments.

A Fund's ability to receive payment of principal, interest and other amounts due
in  connection  with these  investments  will depend  primarily on the financial
condition of the borrower.  In selecting the loans and other direct indebtedness
which a Fund  will  purchase,  the  Adviser  will rely upon its own (and not the
original lending  institution's)  credit analysis of the borrower. As a Fund may
be required to rely upon another  lending  institution  to collect and pass onto
the Fund  amounts  payable  with  respect to the loan and to enforce  the Fund's
rights under the loan and other direct indebtedness,  an insolvency,  bankruptcy
or reorganization of the lending  institution may delay or prevent the Fund from
receiving  such  amounts.  In such  cases,  the Fund will  evaluate  as well the
creditworthiness of the lending institution and will treat both the borrower and
the  lending  institution  as an  "issuer"  

                                        4
<PAGE>
of the loan for purposes of certain  investment  restrictions  pertaining to the
diversification of the Fund's portfolio investments. The highly leveraged nature
of many such loans and other direct  indebtedness  may make such loans and other
direct  indebtedness  especially  vulnerable  to adverse  changes in economic or
market conditions.  Investments in such loans and other direct  indebtedness may
involve additional risk to a Fund.

   
Mortgage   Pass-Through   Securities:   The  Special   Opportunities  Fund,  the
Convertible  Securities  Fund and the Real  Estate  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 premiums
generally increase with falling interest rates and decrease with rising interest
rates. Like other fixed income securities, when interest rates rise the value of
mortgage pass-through securities 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.

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

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

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

FHLMC is also a government-sponsored  corporation owned by private stockholders.
FHLMC issues  Participation  Certificates  ("PCs") which represent  interests in
conventional  mortgages (i.e., not federally  insured or guaranteed) for FHLMC's
national  portfolio.  FHLMC  guarantees  timely payment of interest and ultimate

                                        5
<PAGE>
collection  of principal  regardless  of the status of the  underlying  mortgage
loans.

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

   
Zero  Coupon  Bonds,   Deferred  Interest  Bonds  and  PIK  Bonds:  The  Special
Opportunities Fund, the Convertible Securities Fund and the Real Estate Fund may
invest in zero  coupon  bonds,  deferred  interest  bonds and bonds on which the
interest is payable in kind ("PIK  bonds").  Zero coupon and  deferred  interest
bonds are debt obligations which are issued at a significant  discount from face
value.  The  discount  approximates  the total amount of interest the bonds will
accrue and compound over the period until maturity or the first interest payment
date at a rate of interest  reflecting  the market  rate of the  security at the
time of issuance. While zero coupon bonds do not require the periodic payment of
interest,  deferred  interest  bonds  provide  for a period of delay  before the
regular payment of interest begins. PIK bonds are debt obligations which provide
that the issuer 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 than
debt obligations which make regular payments of interest.  Each 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
each Fund's distribution obligations.

Short Sales: The Special  Opportunities  Fund, the Convertible  Securities Fund,
the Science and Technology  Fund and the Real Estate Fund each may seek to hedge
investments  or realize  additional  gains through short sales.  Short sales are
transactions  in which a Fund sells a security it does not own, in  anticipation
of a  decline  in  the  market  value  of  that  security.  To  complete  such a
transaction,  the Fund must borrow the  security to make  delivery to the buyer.
The Fund then is obligated to replace the security  borrowed by purchasing it at
the market price at the time of replacement.  The price at such time may be more
or less  than the price at which the  security  was sold by the Fund.  Until the
security is replaced,  the Fund is required to repay the lender any dividends or
interest which accrue during the period of the loan. To borrow the security, the
Fund also may be required to pay a premium, which would increase the cost of the
security  sold.  The net  proceeds  of the short  sale will be  retained  by the
broker,  to the extent  necessary to meet margin  requirements,  until the short
position is closed out. The Fund also will incur  transaction costs in effecting
short sales.

A Fund  will  incur a loss as a result  of the  short  sale if the  price of the
security  increases between the date of the short sale and the date on which the
Fund replaces the borrowed  security.  The Fund will realize a gain if the price
of the security  declines in price between  those dates.  The amount of any gain
will be decreased,  and the amount of any loss  increased,  by the amount of the
premium,  dividends  or interest  the Fund may be required to pay in  connection
with a short sale.

The Special Opportunities Fund, the Convertible Securities Fund, the Science and
Technology  Fund and the Real Estate Fund may each make short sales "against the
box," i.e., when a security identical to or convertible or exchangeable into one
owned by the Fund is borrowed  and sold short.  Each Fund may also enter into so
called "naked" short sales,  i.e., when a security  identical to or exchangeable
into the security borrowed and sold short is not owned by the Fund.

A Fund will not sell short  securities whose underlying value (minus any amounts
deposited as margin) exceeds 40% of the value of the Fund's net assets.
    

Whenever the Fund engages in short sales, it segregates cash or U.S.  Government
securities  in an amount  that,  when  combined  with the  amount of  collateral
deposited with the broker in connection with the short sale,  equals the current
market value of the security  sold short.  The  segregated  assets are marked to
market daily.

   
Investment in Other Investment  Companies:  The Real Estate Fund's investment in
other investment companies, as described in the Prospectus, is limited in amount
by the Investment  Company Act of 1940, as amended (the "1940 Act"), so that the
Fund may  purchase  shares  in  another  investment  company  unless  (i) such a
purchase  would  cause  the Fund to own in  aggregate  more than 3% of the total
outstanding  voting  stock of the company or (ii) such a purchase  would cause a
Fund to have more than 5% of its 

                                        6
    
<PAGE>

   
total assets  invested in one  investment  company or more than 10% of its total
assets invested in aggregate in all other investment companies.  Such investment
may also  involve the payment of  substantial  premiums  above the value of such
investment  companies'  portfolio  securities,  and  the  total  return  on such
investment  will be reduced  by the  operating  expenses  and fees of such other
investment companies, including advisory fees.
    

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

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

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

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

The most  significant  factor in the  performance  of swaps,  caps,  floors  and
collars is the change in the specific  interest  rate,  currency or other factor
that determines the amount of payments to be made under the arrangement.  If the
Adviser  is  incorrect  in  its  forecasts  of  such  factors,   the  investment
performance  of a Fund  would  be less  than  what it would  have  been if these
investment  techniques had not been used. If a swap agreement calls for payments
by a Fund,  the Fund  must be  prepared  to make  such  payments  when  due.  In
addition, if the counterparty's creditworthiness declined, the value of the swap
agreement would be likely to decline, potentially resulting in losses.

If the counterparty  defaults,  a Fund's risk of loss consists of the net amount
of  payments  that the Fund is  contractually  entitled  to  receive.  Each Fund
anticipates that it will be able to eliminate or reduce its exposure under these
arrangements  by  assignment  or  other  disposition  or  by  entering  into  an
offsetting agreement with the same or another counterparty.

Options on Securities:  Each Fund may write (sell) covered put and call options,
and purchase put and call options,  on securities.  Call and put options written
by a Fund may be covered in the manner set forth below.

   
A call  option  written  by a Fund is  "covered"  if the Fund owns the  security
underlying  the call or has an  absolute  and  immediate  right to acquire  that
security  without   additional  cash   consideration  (or  for  additional  cash
consideration  segregated  by the Fund) upon  conversion  or  exchange  of other
securities held in its portfolio.  A call option is also covered if a Fund holds
a call on the same security and in the same principal amount as the call written
where  the  exercise  price  of the call  held (a) is equal to or less  than the
exercise  price of the call written or (b) is greater than the exercise price of
the call written if the difference is segregated by the Fund in liquid assets. A
put option written by a Fund is "covered" if the Fund  segregates  liquid assets
with a value  equal  to the  exercise  price,  or else  holds a put on the  same
security and in the same principal  amount as the put written where the 
    
                                        7
<PAGE>
   

exercise price of the put held is equal to or greater than the exercise price of
the put  written  or where the  exercise  price of the put held is less than the
exercise price of the put written if the difference is segregated by the Fund in
liquid  assets.  Put and call  options  written by a Fund may also be covered in
such other manner as may be in accordance with the  requirements of the exchange
on which, or the counterparty  with which, the option is traded,  and applicable
laws and  regulations.  If the  writer's  obligation  is not so  covered,  it is
subject to the risk of the full change in value of the underlying  security from
the time the option is written until exercise.
    

Effecting a closing transaction in the case of a written call option will permit
a Fund to write  another call option on the  underlying  security  with either a
different exercise price or expiration date or both, or in the case of a written
put option will  permit the Fund to write  another put option to the extent that
the  exercise  price  thereof  is  secured  by  deposited  liquid  assets.  Such
transactions  permit a Fund to generate  additional  premium income,  which will
partially  offset declines in the value of portfolio  securities or increases in
the cost of securities  to be acquired.  Also,  effecting a closing  transaction
will  permit the cash or proceeds  from the  concurrent  sale of any  securities
subject to the option to be used for other investments of a Fund,  provided that
another  option on such  security is not  written.  If a Fund  desires to sell a
particular security from its portfolio on which it has written a call option, it
will effect a closing  transaction  in  connection  with the option  prior to or
concurrent with the sale of the security.

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

The Fund may write options in connection with buy-and-write  transactions;  that
is, a Fund may  purchase a security  and then write a call option  against  that
security.  The exercise  price of the call option the Fund  determines  to write
will depend upon the expected  price movement of the  underlying  security.  The
exercise  price  of a  call  option  may be  below  ("in-the-money"),  equal  to
("at-the-money")  or  above   ("out-of-the-money")  the  current  value  of  the
underlying   security  at  the  time  the  option  is   written.   Buy-and-write
transactions  using  in-the-money  call  options may be used when it is expected
that the price of the  underlying  security will decline  moderately  during the
option period.  Buy-and-write  transactions using  out-of-the-money call options
may be used when it is expected that the premiums received from writing the call
option plus the  appreciation in the market price of the underlying  security up
to the exercise price will be greater than the  appreciation in the price of the
underlying   security   alone.  If  the  call  options  are  exercised  in  such
transactions,  a Fund's  maximum  gain will be the  premium  received  by it for
writing the option,  adjusted upwards or downwards by the difference between the
Fund's  purchase  price of the  security and the  exercise  price,  less related
transaction  costs.  If the  options  are not  exercised  and the  price  of the
underlying security declines, the amount of such decline will be offset in part,
or entirely, by the premium received.

The  writing  of  covered  put  options  is  similar  in  terms  of  risk/return
characteristics  to  buy-and-write  transactions.  If the  market  price  of the
underlying  security  rises or otherwise is above the  exercise  price,  the put
option  will expire  worthless  and a Fund's gain will be limited to the premium
received,  less related transaction costs. If the market price of the underlying
security  declines or otherwise is below the exercise price, a Fund may elect to
close the position or retain the option until it is exercised, at which time the
Fund will be required to take delivery of the security at the exercise  price; a
Fund's return will be the premium  received from the put option minus the amount
by which the market  price of the security is below the  exercise  price,  which
could result in a loss.  Out-of-the-money,  at-the-money  and  in-the-money  put
options may be used by a Fund in the same market  environments that call options
are used in equivalent buy-and-write transactions.

Each  Fund may also  write  combinations  of put and  call  options  on the same
security,  known as  "straddles,"  with the same exercise  price and  expiration
date. By writing a straddle, a Fund undertakes a simultaneous obligation to sell
and  purchase  the  same  security  in the  event  that  one of the  options  is
exercised.  If the price of the security  subsequently  rises sufficiently above
the exercise price to cover the amount of the premium and transaction costs, the
call  will  likely  be  exercised  and the  Fund  will be  required  to sell the
underlying  security at a below market price. This loss may be offset,  however,
in whole or part,  by the  premiums  received on the writing of the two options.

                                        8
<PAGE>

Conversely,  if the price of the security declines by a sufficient  amount,  the
put will likely be exercised. The writing of straddles will likely be effective,
therefore,  only where the price of the security  remains stable and neither the
call nor the put is exercised.  In those  instances  where one of the options is
exercised,  the loss on the  purchase  or sale of the  underlying  security  may
exceed the amount of the premiums received.

By writing a call  option,  a 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,  a Fund assumes the risk that it may be
required to purchase the  underlying  security  for an exercise  price above its
then-current  market  value,  resulting  in a capital  loss unless the  security
subsequently appreciates in value. The writing of options on securities will not
be undertaken by a Fund solely for hedging  purposes,  and could involve certain
risks which are not present in the case of hedging transactions.  Moreover, even
where options are written for hedging  purposes,  such  transactions  constitute
only a partial  hedge against  declines in the value of portfolio  securities or
against increases in the value of securities to be acquired, up to the amount of
the premium.

Each Fund may also  purchase  options  for hedging  purposes or to increase  its
return.  Put options may be purchased to hedge against a decline in the value of
portfolio securities. If such decline occurs, the put options will permit a Fund
to sell the securities at the exercise  price,  or to close out the options at a
profit. By using put options in this way, a Fund will reduce any profit it might
otherwise have realized in the underlying  security by the amount of the premium
paid for the put option and by transaction costs.
   
Each Fund may also  purchase  call  options to hedge  against an increase in the
price of securities that the Fund anticipates  purchasing in the future. If such
increase occurs, the call option will permit the Fund to purchase the securities
at the exercise price, or to close out the options at a profit. The premium paid
for the call option plus any transaction costs will reduce the benefit,  if any,
realized by a Fund upon  exercise of the  option,  and,  unless the price of the
underlying security rises  sufficiently,  the option may expire worthless to the
Fund.

Reset Options:  In certain  instances,  each Fund may enter into options on U.S.
Treasury  securities  which provide for periodic  adjustment of the strike price
and may also provide for the periodic  adjustment of the premium during the term
of each such option. Like other types of options, these transactions,  which may
be referred  to as "reset"  options or  "adjustable  strike"  options  grant the
purchaser  the right to purchase (in the case of a call) or sell (in the case of
a put), a specified  type of U.S.  Treasury  security at any time up to a stated
expiration date (or, in certain  instances,  on such date). In contrast to other
types of options,  however,  the price at which the  underlying  security may be
purchased  or sold under a "reset"  option is  determined  at various  intervals
during  the term of the  option,  and such price  fluctuates  from  interval  to
interval based on changes in the market value of the underlying  security.  As a
result,  the strike price of a "reset" option,  at the time of exercise,  may be
less  advantageous  than if the strike price had been fixed at the initiation of
the option. In addition,  the premium paid for the purchase of the option may be
determined at the termination, rather than the initiation, of the option. If the
premium is paid at  termination,  the Fund assumes the risk that (i) the premium
may be less than the premium  which would  otherwise  have been  received at the
initiation of the option  because of such factors as the  volatility in yield of
the  underlying  Treasury  security over the term of the option and  adjustments
made to the  strike  price of the  option,  and (ii) the  option  purchaser  may
default on its obligation to pay the premium at the termination of the option.
    

Options  on Stock  Indices:  Each Fund may  write  (sell)  covered  call and put
options and purchase  call and put options on stock  indices.  In contrast to an
option on a security,  an option on a stock index  provides  the holder with the
right but not the obligation to make or receive a cash  settlement upon exercise
of the option, rather than the right to purchase or sell a security.  The amount
of this  settlement  is equal to (i) the  amount,  if any,  by which  the  fixed
exercise price of the option exceeds (in the case of a call) or is below (in the
case  of a put)  the  closing  value  of the  underlying  index  on the  date of
exercise, multiplied by (ii) a fixed "index multiplier."

   
Each Fund may cover call  options on stock  indices by owning  securities  whose
price  changes,  in the opinion of the  Adviser,  are  expected to be similar to
those of the underlying  index,  or by having an absolute and immediate right to
acquire such securities without additional cash consideration (or for additional
cash consideration  segregated by the Fund) upon conversion or exchange of other
securities in its portfolio.  Where a Fund covers a call option on a stock index
through  ownership of securities,  such securities may not match the composition
of the index and, in that event, the Fund will not be fully covered and could be
subject  to risk of loss in the  event of  adverse  changes  in the value of the
index.  Each Fund may also cover call options on stock indices by holding a call
on the same index and in the same principal amount as the call written where the
exercise  price of the call held (a) is equal to or less than the exercise price
of the  call  written  or (b) is  greater  than the  exercise  price of the call
written if the difference is segregated by the Fund in liquid assets.  Each Fund
may cover put options on stock indices by segregating liquid assets with a value
equal to the exercise  price, or by holding a put on the same stock index and in
the same principal amount as the put written where the exercise price of the put
    

                                        9
<PAGE>
   

held is equal to or greater than the exercise  price of the put written or where
the exercise  price of the put held is less than the  exercise  price of the put
written if the  difference is segregated by the Fund in liquid  assets.  Put and
call options on stock indices may also be covered in such other manner as may be
in accordance with the rules of the exchange on which, or the counterparty  with
which, the option is traded and applicable laws and regulations.
    

Each  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.  If the value of an index on which a Fund has written
a call option  falls or remains the same,  the Fund will realize a profit in the
form of the premium received (less transaction costs) that could offset all or a
portion of any decline in the value of the  securities  it owns. If the value of
the  index  rises,  however,  the Fund will  realize  a loss in its call  option
position,  which will reduce the benefit of any unrealized  appreciation  in the
Fund's stock investments.  By writing a put option, a Fund assumes the risk of a
decline in the index.  To the extent that the price changes of securities  owned
by a Fund correlate with changes in the value of the index,  writing covered put
options  on  indices  will  increase  a Fund's  losses  in the event of a market
decline, although such losses will be offset in part by the premium received for
writing the option.

Each  Fund  may  also  purchase  put  options  on stock  indices  to  hedge  its
investments  against a decline in value.  By  purchasing a put option on a stock
index,  a Fund will seek to offset a decline in the value of  securities it owns
through  appreciation of the put option. If the value of the Fund's  investments
does  not  decline  as  anticipated,  or if the  value  of the  option  does not
increase,  the Fund's  loss will be limited to the  premium  paid for the option
plus related transaction costs. The success of this strategy will largely depend
on the accuracy of the correlation between the changes in value of the index and
the changes in value of the Fund's security holdings.
   

The purchase of call  options on stock  indices may be used by a Fund to attempt
to reduce  the risk of  missing a broad  market  advance,  or an  advance  in an
industry or market  segment,  at a time when the Fund holds  uninvested  cash or
short-term debt securities awaiting investment. When purchasing call options for
this  purpose,  a Fund will also bear the risk of losing all or a portion of the
premium  paid if the value of the  index  does not rise.  The  purchase  of call
options on stock indices when a Fund is  substantially  fully invested is a form
of leverage,  up to the amount of the premium and related transaction costs, and
involves risks of loss and of increased  volatility similar to those involved in
purchasing calls on securities the Fund owns.
    

The index underlying a stock index option may be a "broad-based"  index, such as
the Standard & Poor's 500 Index or the New York Stock Exchange  Composite Index,
the changes in value of which  ordinarily  will  reflect  movements in the stock
market in general. In contrast,  certain options may be based on narrower market
indices, such as the Standard & Poor's 100 Index, or on indices of securities of
particular  industry  groups,  such  as  those  of oil  and  gas  or  technology
companies.  A stock index assigns  relative values to the stocks included in the
index and the index  fluctuates  with changes in the market values of the stocks
so included. The composition of the index is changed periodically.

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

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

                                        10
<PAGE>

are illiquid and, therefore, cannot exceed the SEC illiquidity ceiling.

Options:   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 each 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 a 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.  Each Fund will
treat all or a part of the  formula  price as illiquid  for  purposes of the SEC
illiquidity  ceiling.  Each 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:  Each Fund may purchase and sell futures  contracts on stock
indices,  and may purchase and sell futures  contracts on foreign  currencies or
indices of foreign currencies ("Futures  Contracts").  The Special Opportunities
Fund, the Convertible  Securities Fund and the Real Estate 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  that may become  available  for
trading.  Such investment  strategies will be used for hedging  purposes and for
non-hedging purposes, subject to applicable law.
    

A Futures Contract is a bilateral  agreement providing for the purchase and sale
of a specified type and amount of a financial instrument or foreign currency, or
for the making and  acceptance  of a cash  settlement,  at a stated  time in the
future  for a fixed  price.  By its terms,  a Futures  Contract  provides  for a
specified settlement date on which, in the case of the majority of interest rate
and foreign currency futures contracts,  the fixed income securities or currency
are delivered by the seller and paid for by the purchaser,  or on which,  in the
case of stock index  futures  contracts  and certain  interest  rate and foreign
currency  futures  contracts,  the  difference  between  the  price at which the
contract was entered into and the  contract's  closing value is settled  between
the purchaser and seller in cash.  Futures Contracts differ from options in that
they are bilateral  agreements,  with both the purchaser and the seller  equally
obligated to complete the  transaction.  Futures  Contracts  call for settlement
only on the  expiration  date and cannot be "exercised" at any other time during
their term.

The purchase or sale of a Futures  Contract differs from the purchase or sale of
a security or the  purchase  of an option in that no  purchase  price is paid or
received.  Instead, an amount of cash or cash equivalents,  which varies but may
be as low as 5% or less of the value of the contract, must be deposited with the
broker as "initial margin." Subsequent payments to and from the broker, referred
to as "variation margin," are made on a daily basis as the value of the index or
instrument  underlying the Futures Contract fluctuates,  making positions in the
Futures Contract more or less valuable - a process known as "mark-to-market."

Purchases  or sales of stock  index  futures  contracts  are used to  attempt to
protect a Fund's current or intended stock  investments from broad  fluctuations
in stock prices.  For example,  a Fund may sell stock index futures contracts in
anticipation  of or during a market decline to attempt to offset the decrease in
market value of the Fund's securities  portfolio that might otherwise result. If
such decline occurs, the loss in value of portfolio securities may be offset, in
whole  or  part,  by gains on the  futures  position.  When a Fund is not  fully
invested in the securities market and anticipates a significant  market advance,
it may  purchase  stock index  futures  contracts  in order to gain rapid market
exposure  that  may,  in part  or  entirely,  offset  increases  in the  cost of
securities  that the Fund intends to purchase.  As such  purchases are made, the
corresponding  positions in stock index futures contracts will be closed out. In
a  substantial  majority  of these  transactions,  the Fund will  purchase  such
securities upon  termination of the futures  position,  but under unusual market
conditions, a long futures position may be terminated without a related purchase
of securities.

Interest  rate Futures  Contracts may be purchased or sold to attempt to protect
against  the effects of interest  rate  changes on a Fund's  current or intended
investments in fixed income securities.  For example,  if a Fund owned long-term
bonds and interest  rates were expected to increase,  that Fund might enter into
interest  rate futures  contracts for the sale of debt  securities.  Such a sale
would have much the same effect as selling some of the  long-term  bonds in that
Fund's  portfolio.  If  interest  rates  did  increase,  the  value  of the debt
securities in the portfolio would decline, but the value of that Fund's interest
rate futures  contracts would increase at approximately  the same rate,  thereby
keeping the net asset 

                                        11
<PAGE>

value of that Fund from declining as much as it otherwise would have.

Similarly,  if interest  rates were  expected to decline,  interest rate futures
contracts may be purchased to hedge in anticipation  of subsequent  purchases of
long-term  bonds at higher prices.  Since the  fluctuations  in the value of the
interest rate futures  contracts should be similar to that of long-term bonds, a
Fund could protect  itself  against the effects of the  anticipated  rise in the
value of long-term  bonds without  actually buying them until the necessary cash
became  available or the market had stabilized.  At that time, the interest rate
futures  contracts  could be liquidated and that Fund's cash reserves could then
be used to buy  long-term  bonds on the cash  market.  A Fund  could  accomplish
similar  results by selling  bonds with long  maturities  and investing in bonds
with short  maturities  when interest  rates are expected to increase.  However,
since  the  futures  market  is more  liquid  than the cash  market,  the use of
interest rate futures  contracts as a hedging  technique  allows a Fund to hedge
its interest rate risk without having to sell its portfolio securities.
   

As noted  in the  Prospectus,  a Fund may  purchase  and sell  foreign  currency
futures  contracts  for hedging  purposes,  to attempt to protect its current or
intended   investments  from  fluctuations  in  currency  exchange  rates.  Such
fluctuations could reduce the dollar value of portfolio  securities  denominated
in foreign currencies, or increase the cost of foreign-denominated securities to
be acquired,  even if the value of such  securities  in the  currencies in which
they are denominated  remains  constant.  A Fund may sell futures contracts on a
foreign  currency,  for example,  where it holds securities  denominated in such
currency and it anticipates a decline in the value of such currency  relative to
the dollar.  In the event such decline occurs,  the resulting  adverse effect on
the value of foreign-denominated  securities may be offset, in whole or in part,
by gains on the futures contracts.
    

Conversely,  a  Fund  could  protect  against  a  rise  in the  dollar  cost  of
foreign-denominated securities to be acquired by purchasing futures contracts on
the relevant  currency,  which could offset,  in whole or in part, the increased
cost  of  such  securities  resulting  from a rise in the  dollar  value  of the
underlying  currencies.  Where a Fund  purchases  futures  contracts  under such
circumstances,  however,  and the prices of  securities  to be acquired  instead
decline, the Fund will sustain losses on its futures position which could reduce
or eliminate  the benefits of the reduced  cost of  portfolio  securities  to be
acquired.

Forward  Contracts:  Each Fund may enter into contracts for the purchase or sale
of a specific  currency at a future date at a price set at the time the contract
is entered  into (a "Forward  Contract"),  for  hedging  purposes as well as for
non-hedging  purposes.  Each Fund may also  enter  into  Forward  Contracts  for
"cross-hedging"  purposes as noted in the  Prospectus.  The Fund will enter into
Forward  Contracts  for the  purpose  of  protecting  its  current  or  intended
investments from fluctuations in currency exchange rates.

A Forward  Contract to sell a currency may be entered into where a Fund seeks to
protect  against an  anticipated  increase in the  exchange  rate for a specific
currency which could reduce the dollar value of portfolio securities denominated
in such  currency.  Conversely,  the Fund may enter into a Forward  Contract  to
purchase a given currency to protect against a projected  increase in the dollar
value of  securities  denominated  in such  currency  which the Fund  intends to
acquire.

   
If a hedging transaction in Forward Contracts is successful,  the decline in the
value of portfolio  securities  or the increase in the cost of  securities to be
acquired may be offset,  at least in part,  by profits on the Forward  Contract.
Nevertheless,  by entering into such Forward Contracts, the Fund may be required
to forego  all or a portion  of the  benefits  which  otherwise  could have been
obtained  from  favorable  movements  in  exchange  rates.  Each  Fund  does not
presently intend to hold Forward Contracts entered into until the Value Date, at
which time it would be required to deliver or accept  delivery of the underlying
currency,  but will  seek in most  instances  to  close  out  positions  in such
Contracts by entering into offsetting transactions,  which will serve to fix the
Fund's  profit or loss  based  upon the value of the  Contracts  at the time the
offsetting transaction is executed.

Each Fund has established  procedures which require the use of segregated assets
or "cover" in connection with the purchase and sale of such Contracts.  In those
instances in which the Fund satisfies this  requirement  through  segregation of
assets,  it will  segregate  liquid  assets  which will be marked to market on a
daily basis,  in an amount equal to the value of its  commitments  under Forward
Contracts.
    

Options on Futures  Contracts:  Each Fund also may purchase and write options to
buy or sell those Futures  Contracts in which it may invest ("Options on Futures
Contracts")  as  described  above under  "Futures  Contracts."  Such  investment
strategies  will be used for  hedging  purposes  and for  non-hedging  purposes,
subject to applicable law.

An Option on a Futures Contract provides the holder with the right to enter into
a "long"  position  in the  underlying  Futures  Contract  in the case of a call
option, or a "short" position in the underlying  Futures Contract in the case of
a put option,  at a fixed exercise price up to a stated  expiration  date or, in
the case of certain  options,  on such date.  Upon exercise of the option by the
holder,  the contract market  clearinghouse  establishes a  corresponding  short
position  for

                                        12
<PAGE>

the writer of the option, in the case of a call option, or a corresponding  long
position in the case of a put option.  In the event that an option is exercised,
the  parties  will be subject to all the risks  associated  with the  trading of
Futures Contracts,  such as payment of initial and variation margin deposits. In
addition,  the writer of an Option on a Futures Contract,  unlike the holder, is
subject to initial and variation margin requirements on the option position.

A position in an Option on a Futures Contract may be terminated by the purchaser
or  seller  prior  to  expiration  by  effecting  a  closing  purchase  or  sale
transaction,  subject to the availability of a liquid secondary market, which is
the  purchase  or sale of an option of the same Fund  (i.e.,  the same  exercise
price and  expiration  date) as the option  previously  purchased  or sold.  The
difference between the premiums paid and received represents the trader's profit
or loss on the transaction.

   
Options on Futures  Contracts  that are written or  purchased  by a Fund on U.S.
exchanges  are  traded on the same  contract  market as the  underlying  Futures
Contract,  and,  like  Futures  Contracts,  are  subject  to  regulation  by the
Commodities   Futures  Trading  Commission  (the  "CFTC")  and  the  performance
guarantee  of the  exchange  clearinghouse.  In  addition,  Options  on  Futures
Contracts  may be traded on foreign  exchanges.  A Fund may cover the writing of
call  Options on Futures  Contracts  (a)  through  purchases  of the  underlying
Futures  Contract,  (b) through  ownership  of the  instrument,  or  instruments
included  in the index,  underlying  the  Futures  Contract,  or (c) through the
holding of a call on the same Futures  Contract and in the same principal amount
as the call written where the exercise price of the call held (i) is equal to or
less than the  exercise  price of the call  written or (ii) is greater  than the
exercise  price of the call written if the  difference is segregated by the Fund
in liquid  assets.  A Fund may cover  the  writing  of put  Options  on  Futures
Contracts  (a) through sales of the  underlying  Futures  Contract,  (b) through
segregation  of liquid assets in an amount equal to the value of the security or
index  underlying the Futures  Contract,  or (c) through the holding of a put on
the same Futures  Contract and in the same  principal  amount as the put written
where  the  exercise  price  of the put held is  equal  to or  greater  than the
exercise price of the put written or where the exercise price of the put held is
less than the exercise  price of the put written if the difference is segregated
by the Fund in liquid assets. Put and call Options on Futures Contracts may also
be covered in such other  manner as may be in  accordance  with the rules of the
exchange on which the option is traded and applicable laws and regulations. Upon
the exercise of a call Option on a Futures  Contract written by a Fund, the Fund
will be required to sell the underlying  Futures Contract which, if the Fund has
covered its  obligation  through the  purchase of such  Contract,  will serve to
liquidate  its  futures  position.  Similarly,  where a put  Option on a Futures
Contract  written by a Fund is exercised,  the Fund will be required to purchase
the underlying  Futures  Contract  which, if the Fund has covered its obligation
through the sale of such Contract, will close out its futures position.
    

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

Each Fund may purchase Options on Futures Contracts for hedging purposes instead
of purchasing or selling the underlying Futures Contracts.  For example, where a
decrease in the value of portfolio  securities is  anticipated  as a result of a
projected  market-wide  decline or changes in interest or exchange rates, a Fund
could, in lieu of selling Futures  Contracts,  purchase put options thereon.  In
the event that such decrease occurs, it may be offset, in whole or in part, by a
profit  on the  option.  Conversely,  where it is  projected  that the  value of
securities to be acquired by a Fund will increase prior to acquisition, due to a
market  advance or changes in interest or exchange  rates, a Fund could purchase
call Options on Futures Contracts, rather than purchasing the underlying Futures
Contracts.

Options on  Foreign  Currencies:  Each Fund may  purchase  and write  options on
foreign  currencies  for hedging  purposes in a manner  similar to that in which
futures contracts on foreign currencies, or Forward Contracts, will be utilized.
For  example,  a decline  in the  dollar  value of a foreign  currency  in which
portfolio  securities  are  denominated  will  reduce the  dollar  value of such
securities,  even if their value in the foreign  currency remains  constant.  In
order to protect against such diminutions in the value of portfolio  securities,
a Fund may  purchase  put options on the foreign  currency.  If the value of the
currency does decline,

                                        13
<PAGE>

the Fund will have the right to sell such currency for a fixed amount in dollars
and will thereby  offset,  in whole in part, the adverse effect on its portfolio
which otherwise would have resulted.

Conversely,  where a rise in the dollar value of a currency in which  securities
to be acquired are denominated is projected, thereby increasing the cost of such
securities,  each Fund may purchase call options  thereon.  The purchase of such
options could offset,  at least partially,  the effects of the adverse movements
in  exchange  rates.  As in the case of other  types of  options,  however,  the
benefit to the Fund deriving from purchases of foreign  currency options will be
reduced by the amount of the premium and related transaction costs. In addition,
where  currency  exchange  rates do not move in the  direction  or to the extent
anticipated,  the Fund could sustain losses on transactions in foreign  currency
options  which  would  require it to forego a portion or all of the  benefits of
advantageous  changes  in such  rates.  Each Fund may write  options  on foreign
currencies for the same types of hedging purposes.  For example,  where the Fund
anticipates a decline in the dollar value of foreign-denominated  securities due
to adverse  fluctuations in exchange rates it could, instead of purchasing a put
option,  write a call option on the relevant  currency.  If the expected decline
occurs,  the option will most likely not be  exercised,  and the  diminution  in
value of  portfolio  securities  will be  offset by the  amount  of the  premium
received  less  related  transaction  costs.  As in the case of  other  types of
options, therefore, the writing of Options on Foreign Currencies will constitute
only a partial hedge.

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

ADDITIONAL RISK FACTORS:

Options, Futures and Forward Transactions

Risk of imperfect correlation of hedging instruments with a Fund's portfolio.  A
Fund's ability  effectively  to hedge all or a portion of its portfolio  through
transactions  in  options,  Futures  Contracts,  Options on  Futures  Contracts,
Forward  Contracts  and options on foreign  currencies  depends on the degree to
which price movements in the underlying index or instrument correlate with price
movements  in the  relevant  portion  of the  Fund's  portfolio.  In the case of
futures and options  based on an index,  the  portfolio  will not  duplicate the
components of the index,  and in the case of futures and options on fixed income
securities,  the portfolio securities which are being hedged may not be the same
type of obligation  underlying such contract.  The use of Forward  Contracts for
"cross hedging" purposes may involve greater correlation risks. As a result, the
correlation  probably will not be exact.  Consequently,  the Fund bears the risk
that the price of the  portfolio  securities  being  hedged will not move in the
same amount or direction as the underlying index or obligation.

For  example,  if a Fund  purchases  a put  option  on an  index  and the  index
decreases  less  than  the  value  of the  hedged  securities,  the  Fund  would
experience a loss which is not completely  offset by the put option.  It is also
possible  that  there  may  be a  negative  correlation  between  the  index  or
obligation  underlying  an option or  Futures  Contract  in which the Fund has a
position and the portfolio  securities  the Fund is  attempting to hedge,  which
could  result in a loss on both the  portfolio  and the hedging  instrument.  In
addition,  a Fund may enter into transactions in Forward Contracts or options on
foreign  currencies  in  order  to  hedge  against  exposure  arising  from  the
currencies  underlying such  instruments.  In such  instances,  the Fund will be
subject to the additional risk of imperfect  correlation  between changes in the
value of the currencies  underlying  such forwards or options and changes in the
value of the  currencies  being  hedged.  It should be noted  that  stock  index
futures contracts or options based upon a narrower index of securities,  such as
those of a particular  industry group,  may present greater risk than options or
futures based on a broad market  index.  This is due to the fact that a narrower
index is more  susceptible  to rapid  and  extreme  fluctuations  as a result of
changes in the value of a small number of securities. Nevertheless, where a Fund
enters into transactions in options,  or futures on  narrowly-based  indices for
hedging  purposes,  movements in the value of the index should,  if the hedge is
successful,  correlate  closely with the portion of the Fund's  portfolio or the
intended acquisitions being hedged.

The trading of Futures  Contracts,  options and  Forward  Contracts  for hedging
purposes entails the additional risk of imperfect  correlation between movements
in the  futures  or  option  price  and the  price  of the  underlying  index or
obligation.  The  anticipated  spread between the prices may be distorted due to
the  differences  in the nature of the  markets  such as  differences  in margin
requirements, the 

                                        14
<PAGE>

liquidity of such markets and the  participation  of speculators in the options,
futures and forward markets. In this regard,  trading by speculators in options,
futures and Forward  Contracts has in the past  occasionally  resulted in market
distortions,  which may be difficult or impossible to predict, particularly near
the expiration of such contracts.

The trading of Options on Futures  Contracts  also entails the risk that changes
in the value of the underlying  Futures Contracts will not be fully reflected in
the value of the option. The risk of imperfect correlation,  however,  generally
tends to diminish as the  maturity  date of the Futures  Contract or  expiration
date of the option approaches.

Further,  with  respect  to  options on  securities,  options on stock  indices,
options on currencies and Options on Futures Contracts, a Fund is subject to the
risk of market  movements  between the time that the option is exercised and the
time of  performance  thereunder.  This  could  increase  the extent of any loss
suffered by a Fund in connection with such transactions.

In writing a covered  call option on a security,  index or futures  contract,  a
Fund also incurs the risk that changes in the value of the  instruments  used to
cover the position will not  correlate  closely with changes in the value of the
option or underlying  index or  instrument.  For example,  where a Fund covers a
call option written on a stock index through  segregation  of  securities,  such
securities may not match the  composition of the index,  and the Fund may not be
fully  covered.  As a result,  the Fund  could be subject to risk of loss in the
event of adverse market movements.

The  writing of options on  securities,  options on stock  indices or Options on
Futures Contracts  constitutes only a partial hedge against  fluctuations in the
value of a Fund's  portfolio.  When a Fund  writes an  option,  it will  receive
premium  income in return for the  holder's  purchase of the right to acquire or
dispose  of the  underlying  obligation.  In the  event  that the  price of such
obligation does not rise sufficiently above the exercise price of the option, in
the case of a call, or fall below the exercise  price, in the case of a put, the
option will not be exercised and the Fund will retain the amount of the premium,
less related  transaction  costs,  which will constitute a partial hedge against
any  decline  that may have  occurred  in the Fund's  portfolio  holdings or any
increase in the cost of the instruments to be acquired.

Where the price of the underlying  obligation moves sufficiently in favor of the
holder to warrant exercise of the option,  however, and the option is exercised,
the Fund will incur a loss which may only be  partially  offset by the amount of
the premium it received.

Moreover,  by writing an option,  a Fund may be required to forego the  benefits
which  might  otherwise  have been  obtained  from an  increase  in the value of
portfolio  securities or other assets or a decline in the value of securities or
assets to be acquired.  In the event of the  occurrence  of any of the foregoing
adverse market  events,  a Fund's overall return may be lower than if it had not
engaged in the hedging transactions.

The Funds may enter  transactions  in  options  (except  for  Options on Foreign
Currencies),  Futures  Contracts,  Options  on  Futures  Contracts  and  Forward
Contracts  for  non-hedging  purposes as well as hedging  purposes.  Non-hedging
transactions in such investments  involve greater risks and may result in losses
which may not be offset by  increases in the value of  portfolio  securities  or
declines in the cost of  securities  to be  acquired.  The Funds will only write
covered  options,  such that cash or  securities  necessary to satisfy an option
exercise will be  segregated at all times,  unless the option is covered in such
other manner as may be in accordance with the rules of the exchange on which the
option is traded and applicable laws and regulations.  Nevertheless,  the method
of covering an option  employed by a Fund may not fully  protect it against risk
of loss and, in any event,  the Fund could suffer losses on the option  position
which  might not be offset  by  corresponding  portfolio  gains.  Entering  into
transactions  in Futures  Contracts,  Options on Futures  Contracts  and Forward
Contracts for other than hedging  purposes  could expose the Fund to significant
risk of loss if foreign currency  exchange rates do not move in the direction or
to the extent anticipated.

With respect to the writing of straddles on  securities,  a Fund incurs the risk
that the price of the underlying  security will not remain  stable,  that one of
the options  written will be exercised and that the  resulting  loss will not be
offset by the amount of the premiums  received.  Such  transactions,  therefore,
create  an  opportunity  for  increased  return  by  providing  a Fund  with two
simultaneous  premiums on the same security,  but involve additional risk, since
the Fund may have an option exercised against it regardless of whether the price
of the security increases or decreases.

Risk of a  potential  lack of a liquid  secondary  market.  Prior to exercise or
expiration, a futures or option position can only be terminated by entering into
a closing  purchase or sale  transaction.  This requires a secondary  market for
such  instruments on the exchange on which the initial  transaction  was entered
into. While the Funds will enter into options or futures positions only if there
appears to be a liquid secondary market therefor, there can be no assurance that
such a market will exist for any  particular  contracts at any specific time. In
that event,  it may not be possible to close out a position held by a Fund,  and
the Fund could be  required to purchase  or sell the  instrument  underlying  an
option,  make or receive a cash  settlement  or 

                                        15
<PAGE>

meet ongoing variation margin  requirements.  Under such  circumstances,  if the
Fund has  insufficient  cash available to meet margin  requirements,  it will be
necessary to liquidate portfolio securities or other assets at a time when it is
disadvantageous  to do so.  The  inability  to close  out  options  and  futures
positions,  therefore,  could  have an  adverse  impact  on the  Fund's  ability
effectively to hedge its portfolio, and could result in trading losses.

The liquidity of a secondary  market in a Futures Contract or option thereon may
be  adversely  affected by "daily  price  fluctuation  limits,"  established  by
exchanges,  which  limit the  amount of  fluctuation  in the price of a contract
during a single  trading  day.  Once the  daily  limit has been  reached  in the
contract,  no trades may be  entered  into at a price  beyond  the  limit,  thus
preventing  the  liquidation  of open futures or option  positions and requiring
traders to make additional margin deposits. Prices have in the past moved to the
daily limit on a number of consecutive trading days.

The  trading of Futures  Contracts  and  options is also  subject to the risk of
trading  halts,  suspensions,  exchange  or  clearinghouse  equipment  failures,
government  intervention,  insolvency of a brokerage  firm or  clearinghouse  or
other  disruptions  of normal  trading  activity,  which  could at times make it
difficult or impossible  to liquidate  existing  positions or to recover  excess
variation margin payments.

Margin.  Because  of low  initial  margin  deposits  made upon the  opening of a
futures or forward  position  and the  writing of an option,  such  transactions
involve  substantial  leverage.  As a result,  relatively small movements in the
price of the  contract  can result in  substantial  unrealized  gains or losses.
Where a Fund enters into such  transactions  for  hedging  purposes,  any losses
incurred in connection  therewith should, if the hedging strategy is successful,
be offset, in whole or in part, by increases in the value of securities or other
assets held by the Fund or decreases in the prices of securities or other assets
the Fund  intends to acquire.  Where a Fund enters  into such  transactions  for
other than  hedging  purposes,  the  margin  requirements  associated  with such
transactions could expose the Fund to greater risk.

Trading and  position  limits.  The  exchange  on which  futures and options are
traded may impose  limitations  governing the maximum number of positions on the
same side of the market and involving the same underlying  instrument  which may
be held by a single  investor,  whether  acting  alone or in concert with others
(regardless  of  whether  such  contracts  are  held on the  same  or  different
exchanges  or held or written  in one or more  accounts  or through  one or more
brokers).  Further,  the CFTC and the various  contract markets have established
limits referred to as "speculative  position  limits" on the maximum net long or
net short position which any person may hold or control in a particular  futures
or option contract.  An exchange may order the liquidation of positions found to
be  in  violation  of  these  limits  and  it  may  impose  other  sanctions  or
restrictions.  The Adviser  does not  believe  that these  trading and  position
limits will have any adverse impact on the strategies for hedging the portfolios
of the Fund.

Risks of Options on Futures Contracts. The amount of risk a Fund assumes when it
purchases  an Option on a Futures  Contract is the premium  paid for the option,
plus related  transaction  costs.  In order to profit from an option  purchased,
however,  it may be  necessary  to  exercise  the  option and to  liquidate  the
underlying  Futures  Contract,  subject  to the risks of the  availability  of a
liquid  offset  market  described  herein.  The writer of an Option on a Futures
Contract is subject to the risks of commodity  futures  trading,  including  the
requirement of initial and variation margin payments,  as well as the additional
risk that  movements in the price of the option may not correlate with movements
in the price of the underlying security, index, currency or Futures Contract.

Risks of  transactions  related  to  foreign  currencies  and  transactions  not
conducted  on U.S.  exchanges.  Transactions  in  Forward  Contracts  on foreign
currencies,   as  well  as  futures  and  options  on  foreign   currencies  and
transactions  executed  on  foreign  exchanges,   are  subject  to  all  of  the
correlation,  liquidity and other risks outlined  above.  In addition,  however,
such  transactions  are subject to the risk of  governmental  actions  affecting
trading in or the prices of currencies  underlying such  contracts,  which could
restrict or eliminate trading and could have a substantial adverse effect on the
value of positions held by a Fund. Further, the value of such positions could be
adversely  affected by a number of other complex  political and economic factors
applicable to the countries issuing the underlying currencies.

Further,  unlike  trading  in most  other  types  of  instruments,  there  is no
systematic  reporting  of last sale  information  with  respect  to the  foreign
currencies  underlying contracts thereon. As a result, the available information
on which trading  systems will be based may not be as complete as the comparable
data on which a Fund makes  investment and trading  decisions in connection with
other transactions.  Moreover,  because the foreign currency market is a global,
24-hour market, events could occur in that market which will not be reflected in
the forward,  futures or options market until the following day,  thereby making
it more difficult for the Fund to respond to such events in a timely manner.

Settlements  of  exercises  of  over-the-counter  Forward  Contracts  or foreign
currency options  generally must occur within the country issuing the underlying
currency,  which in turn  requires  traders to accept or make  delivery  of such
currencies in conformity with any U.S. or foreign  restrictions  and regulations
regarding the maintenance of foreign banking relationships, fees, taxes or other
charges.

                                        16
<PAGE>

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

In  addition,  over-the-counter  transactions  can only be  entered  into with a
financial  institution  willing to take the opposite  side, as  principal,  of a
Fund's  position  unless  the  institution  acts as  broker  and is able to find
another  counterparty willing to enter into the transaction with the Fund. Where
no such  counterparty  is  available,  it will not be  possible  to enter into a
desired transaction. There also may be no liquid secondary market in the trading
of  over-the-counter  contracts,  and a Fund could be required to retain options
purchased  or  written,  or Forward  Contracts  entered  into,  until  exercise,
expiration  or maturity.  This in turn could limit the Fund's  ability to profit
from open positions or to reduce losses experienced, and could result in greater
losses.
   

Further,  over-the-counter  transactions  are not subject to the guarantee of an
exchange  clearinghouse,  and a Fund will  therefore  be  subject to the risk of
default  by, or the  bankruptcy  of, the  financial  institution  serving as its
counterparty.  One or more of such  institutions  also may decide to discontinue
their role as  market-makers  in a  particular  currency  or  security,  thereby
restricting  the Fund's ability to enter into desired  hedging  transactions.  A
Fund will enter into an  over-the-counter  transaction  only with parties  whose
creditworthiness has been reviewed and found satisfactory by the Adviser.

Options on securities,  options on stock indices, Futures Contracts,  Options on
Futures  Contracts and options on foreign  currencies may be traded on exchanges
located in foreign countries. Such transactions may not be conducted in the same
manner as those entered into on U.S. exchanges,  and may be subject to different
margin, exercise,  settlement or expiration procedures. As a result, many of the
risks of  over-the-counter  trading  may be  present  in  connection  with  such
transactions.
    

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

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

   
Policies  on the use of futures and  options on futures  contracts.  In order to
assure that the Fund will not be deemed to be a "commodity pool" for purposes of
the Commodity  Exchange Act,  regulations  of the CFTC require that a Fund enter
into transactions in Futures Contracts, Options on Futures Contracts and Options
on Foreign Currencies traded on a CFTC-regulated exchange only (i) for bona fide
hedging purposes (as defined in CFTC regulations), or (ii) for hedging purposes,
provided  that the  aggregate  initial  margin and  premiums to  establish  such
non-bona fide hedging  positions does not exceed 5% of the liquidation  value of
the Fund's assets,  after taking into account  unrealized profits and unrealized
losses on any such  contracts  the Fund has  entered  into,  and  excluding,  in

                                        17
    
<PAGE>
   

computing  such 5%, the  in-the-money  amount with  respect to an option that is
in-the-money at the time of purchase.
    

Risks of investing in Lower Rated Bonds

   
The Special Opportunities Fund, the Convertible Securities Fund, the Science and
Technology Fund and the Real Estate Fund may invest in fixed income  securities,
and may  invest  in  convertible  securities,  rated  Baa by  Moody's  Investors
Service,  Inc. ("Moody's") or BBB by Standard & Poor's Ratings Services ("S&P"),
Fitch IBCA, Inc. ("Fitch") or Duff & Phelps Credit Rating Co. ("Duff & Phelps"),
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  Funds may also  invest in fixed  income  securities  rated Ba or lower by
Moody's or BB or lower by S&P, Fitch or Duff & Phelps,  and  comparable  unrated
securities  (commonly  known as "junk  bonds")  to the extent  described  in the
Prospectus.  No minimum rating standard is required by a Fund.  These securities
are considered  speculative and, while generally  providing  greater income than
investments in higher rated  securities,  will involve greater risk of principal
and income (including the possibility of default or bankruptcy of the issuers of
such securities) and may involve greater  volatility of price (especially during
periods of economic  uncertainty or change) than securities in the higher rating
categories  and because  yields vary over time, no specific  level of income can
ever be  assured.  These  lower  rated high  yielding  fixed  income  securities
generally  tend to  reflect  economic  changes  (and the  outlook  for  economic
growth),  short-term  corporate  and  industry  developments  and  the  market's
perception  of  their  credit  quality   (especially  during  times  of  adverse
publicity)  to a  greater  extent  than  higher  rated  securities  which  react
primarily to fluctuations in the general level of interest rates (although these
lower rated fixed  income  securities  are also  affected by changes in interest
rates). In the past,  economic  downturns or an increase in interest rates have,
under certain circumstances, caused a higher incidence of default by the issuers
of  these  securities  and may do so in the  future,  especially  in the case of
highly  leveraged  issuers.  The prices for these  securities may be affected by
legislative and regulatory developments.  The market for these lower rated fixed
income  securities may be less liquid than the market for investment grade fixed
income  securities.  Furthermore,  the liquidity of these lower rated securities
may be affected by the market's  perception of their credit quality.  Therefore,
the  Adviser's  judgment  may at times  play a  greater  role in  valuing  these
securities than in the case of investment grade fixed income securities,  and it
also may be more difficult during times of certain adverse market  conditions to
sell these lower rated  securities to meet redemption  requests or to respond to
changes in the market.
    

While the  Adviser  may refer to ratings  issued by  established  credit  rating
agencies,  it is not a Fund's policy to rely  exclusively  on ratings  issued by
these rating agencies,  but rather to supplement such ratings with the Adviser's
own  independent  and  ongoing  review of credit  quality.  To the extent a Fund
invests in these lower  rated  securities,  the  achievement  of its  investment
objectives may be a more dependent on the Adviser's own credit  analysis than in
the case of a fund  investing in higher quality fixed income  securities.  These
lower rated  securities  may also include zero coupon bonds,  deferred  interest
bonds and PIK bonds.

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

The  policies  stated  above  are not  fundamental  and may be  changed  without
shareholder approval, as may each Fund's investment objective.

Investment Restrictions.

   
Each Fund has adopted the following restrictions which cannot be changed without
the approval of the holders of a majority of a Fund's shares (which,  as used in
this SAI, means the lesser of (i) more than 50% of the outstanding shares of the
Trust or a series or class, as applicable or (ii) 67% or more of the outstanding
shares of the Trust or a series or class, as applicable, present at a meeting at
which  holders  of more  than 50% of the  outstanding  shares  of the Trust or a
series or class,  as applicable are  represented in person or by proxy).  Except
for  Investment   Restriction  (1)  regarding   borrowing  and   non-fundamental
investment   policy  (1)  regarding   illiquid   securities,   these  investment
restrictions  and policies are adhered to at the time of purchase of utilization
of assets; a subsequent change in circumstances will not be considered to result
in a violation of policy.
    

Each Fund may not:

(1) borrow amounts in excess of 331/3 of its total assets including amounts 
borrowed;

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

(3)  issue  any  senior  securities  except as  permitted  by the 1940 Act;  for
purposes of this restriction,  collateral  arrangements with respect to any type
of option (including  Options on Futures  Contracts,  Options,  Options on Stock
Indices  and Options on Foreign  Currencies),  short  sale,  Forward  Contracts,
Futures  Contracts,   any  other  type  of  

                                        18
    
<PAGE>
   

futures  contract,  and  collateral  arrangements  with  respect to initial  and
variation margin, are not deemed to be the issuance of a senior security; or

(4) make loans to other persons; for these purposes,  the purchase of short-term
commercial  paper,  the  purchase  of a  portion  or all  of an  issue  of  debt
securities,  the lending of portfolio securities,  or the investment of a Fund's
assets in repurchase agreements, shall not be considered the making of a loan.

Each Fund except the Real Estate Fund may not:

(5) purchase or sell real estate (including  limited  partnership  interests but
excluding  securities secured by real estate or interests therein and securities
of companies,  such as real estate investment trusts,  which deal in real estate
or interests therein),  interests in oil, gas or mineral leases,  commodities or
commodity contracts (excluding Options, Options on Futures Contracts, Options on
Stock Indices, Options on Foreign Currency and any other type of option, Futures
Contracts,  any other type of futures  contract,  and Forward  Contracts) in the
ordinary  course of its  business.  Each Fund  reserves the freedom of action to
hold and to sell real estate, mineral leases, commodities or commodity contracts
(including  Options,  Options on Futures  Contracts,  Options on Stock  Indices,
Options on Foreign Currency and any other type of option, Futures Contracts, any
other type of futures contract,  and Forward Contracts)  acquired as a result of
the ownership of securities;

(6)  purchase any  securities  of an issuer of a  particular  industry,  if as a
result,  more than 25% of its gross  assets would be invested in  securities  of
issuers whose  principal  business  activities are in the same industry  (except
obligations  issued or  guaranteed  by the U.S.  Government  or its agencies and
instrumentalities and repurchase agreements collateralized by such obligations).

The Real Estate Fund may not:

(7)  purchase  or sell  interests  therein),  interests  in oil,  gas or mineral
leases,  commodities  or  commodity  contracts  (excluding  Options,  Options on
Futures Contracts, Options on Stock Indices, Options on Foreign Currency and any
other type of option, Futures Contracts, any other type of futures contract, and
Forward  Contracts) in the ordinary  course of its business.  Each Fund reserves
the  freedom  of  action  to hold and to sell  mineral  leases,  commodities  or
commodity contracts (including Options, Options on Futures Contracts, Options on
Stock Indices, Options on Foreign Currency and any other type of option, Futures
Contracts,  any other type of futures contract,  and Forward Contracts) acquired
as a result of the ownership of securities;

(8) purchase  any  security  of, as a result,  more than 25% of its total assets
would be invested in the securities of companies having their principal business
activities in the same industry,  except that the Fund will invest more than 25%
of its total assets in the real estate industry (this  limitation does not apply
to  securities  issued or  guaranteed  by the United  States  government  or its
agencies or instrumentalities).

In addition,  each Fund will not, as a matter of nonfundamental policy which may
be changed  without  shareholder  approval  (only  policies (1), (3) (8) and (9)
apply to the Real Estate Fund):
    

     (1)  invest in illiquid investments,  including securities subject to legal
          or contractual restrictions on resale or for which there is no readily
          available market (e.g.,  trading in the security is suspended,  or, in
          the case of unlisted securities, where no market exists), if more than
          15% of a Fund's net assets  (taken at market  value) would be invested
          in such securities.  Repurchase agreements maturing in more than seven
          days will be deemed to be illiquid for purposes of a Fund's limitation
          on  investment  in  illiquid  securities.   Securities  that  are  not
          registered  under  the  1933  Act and sold in  reliance  on Rule  144A
          thereunder,  but are  determined  to be liquid by the Trust's Board of
          Trustees (or its delegee), will not be subject to this 15% limitation;

     (2)  invest  more than 15% of the value of a Fund's net  assets,  valued at
          the lower of cost or market, in warrants. Included within such amount,
          but not to exceed  10% of the  value of a Fund's  net  assets,  may be
          warrants  which  are not  listed  on the New  York or  American  Stock
          Exchange;  warrants  acquired  by a  Fund  in  units  or  attached  to
          securities may be deemed to be without value;

     (3)  invest for the purpose of exercising control or management;

     (4)  purchase  securities issued by any other investment  company in excess
          of the amount permitted by the 1940 Act; currently, each Fund does not
          intend to invest more than 5% of its net assets in such securities;

     (5)  purchase  or retain  securities  of an issuer  any of whose  officers,
          directors,  trustees or  security  holders is an officer or Trustee of
          each Fund, or is an officer or a director of the investment adviser of
          each Fund, if one or more of such persons also owns  beneficially more
          than 1/2 of 1% of the  securities  of such  issuer,  and such  persons
          owning  more  than  1/2  of  1%  of  such   securities   together  own
          beneficially more than 5% of such securities;

     (6)  purchase any  securities  or evidences of interest  therein on margin,
          except  that  a Fund  may  obtain  such  short-term  credit  as may be
          necessary for the clearance of any  transaction and except that a Fund
          may make  margin  deposits  in  connection  with  any  type of  option
          (including  Options on Futures  Contracts,  Options,  Options on Stock
          Indices and Options on Foreign  Currencies),  any short sale, any type
          of  futures  contract  (including  Futures  Contracts),   and  Forward
          Contracts;

     (7)  invest more than 5% of its gross assets in companies which,  including
          predecessors,   controlling  persons,   sponsoring  entities,  general
          partners  and  guarantors,  have a record  of less than  three  years'
          continuous operation or relevant business experience;

     (8)  pledge,  mortgage  or  hypothecate  in  excess of 33 1/3% of its gross
          assets. For purposes of this restriction, collateral arrangements with
          respect to any type of option (including Options on Futures Contracts,
          Options,  Options on Stock Indices and Options on Foreign Currencies),
          any  short  sale,  any type of  futures  contract  (including  Futures
          Contracts),  Forward  Contracts  and payments of initial and variation
          margin in connection therewith, are not considered a pledge of assets;

     (9)  purchase  or sell any put or call option or any  combination  thereof,
          provided  that this shall not  prevent  (a) the  purchase,  ownership,
          holding or sale of (i)  warrants  where the grantor of the warrants is
          the issuer of the underlying securities or (ii) put or call options or
          combinations   thereof   with  respect  to   securities,   indexes  of
          securities,  Options  on  Foreign  Currencies  or any type of  futures
          contract (including Futures Contracts) or (b) the purchase, ownership,
          holding or sale of contracts for the future  delivery of securities or
          currencies; or

   
     (10) invest  25% or  more  of the  market  value  of its  total  assets  in
          securities  of issuers  in any one  industry;  provided  that the Real
          Estate  Fund may invest  25% or more of the market  value of the total
          assets in the real estate industry.

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

   

Each Trustee and officer holds comparable  positions with certain  affiliates of
MFS or with certain other funds of which MFS or a subsidiary  is the  investment
adviser or  distributor.  Messrs.  Shames and Scott,  Directors  of MFD, and Mr.
Cavan,  the  Secretary of MFD,  hold similar  positions  with certain  other MFS
affiliates.  Mr.  Bailey is a Director of Sun Life  Assurance  Company of Canada
(U.S.) ("Sun Life of Canada  (U.S.)"),  the corporate  parent of MFS. While each
Fund pays the compensation of the  non-interested  Trustees and Mr. Bailey,  the
Trustees are currently waiving their rights to receive such fees.

    
Each Fund has adopted a  retirement  plan for  non-interested  Trustees  and Mr.
Bailey.  Under this plan, a Trustee will retire upon  reaching age 75 and if the
Trustee  has  completed  at least 5 years of  service,  he would be  entitled to
annual  payments  during his  lifetime  of up to 50% of such  Trustee's  average
annual compensation (based on the three years prior to his retirement) depending
on his length of service.  A Trustee may also retire prior to age 75 and receive
reduced  payments if he has  completed  at least 5 years of  service.  Under the
plan, a Trustee (or his  beneficiaries)  will also receive benefits for a period
of time in the event the Trustee is disabled or dies.  These  benefits will also
be based on the Trustee's  average  annual  compensation  and length of service.
There is no retirement plan provided by the Trust for Messrs.  Scott and Shames.
Each Fund will accrue its allocable  portion of compensation  expenses under the
retirement  plan each year to cover the current year's service and amortize past
service cost.

As of February 28, 1998,  the Trustees and officers as a group owned  23,318.062
Class A shares of the Core Growth Fund,  or 10.68% of the Core Growth Fund,  and

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

Investment Adviser

   
MFS and its predecessor  organizations have a history of money management dating
from 1924. MFS is a subsidiary of Sun Life of Canada (U.S.) Financial  Holdings,
Inc., which is an indirect wholly owned subsidiary of Sun Life Assurance Company
of Canada ("Sun Life").

Investment  Advisory  Agreement  -- The Adviser  manages  each Fund  pursuant to
separate Investment Advisory Agreements,  dated January 2, 1996, with respect to
the Core Growth Fund and the Special  Opportunities  Fund, January 2, 1997, with
respect to the Convertible  Securities  Fund, the Blue Chip Fund and the Science
and  Technology  Fund,  and March 16, 1998 with  respect to the Real Estate Fund
(the "Advisory Agreements"). Under the Advisory Agreements, the Adviser provides
each Fund with overall investment advisory services. Subject to such policies as
the Trustees may  determine,  the Adviser  makes  investment  decisions for each
Fund.  For these  services,  the  Adviser  receives  an annual  management  fee,
computed and paid  monthly,  as disclosed  in the  Prospectus  under the heading
"Management of the Funds."
    

For the period from the  commencement  of investment of operations to the fiscal
year end of August 31, 1997, the Adviser waived its right to receive  management
fees from each Fund.  The Adviser is currently  waiving its right to receive its
management fee from each Fund.

The Adviser pays the compensation of the Trust's officers and of any Trustee who
is an officer of the Adviser.

Each  Advisory  Agreement  will remain in effect until August 1, 1998,  and will
continue in effect thereafter only if such continuance is specifically  approved
at least  annually  by the Board of  Trustees  or by vote of a  majority  of the
Fund's shares (as defined in "Investment Objective,  Policies and Restrictions")
and, in either  case,  by a majority of the  Trustees who are not parties to the
Advisory Agreement or interested persons of any such party.

Each Advisory  Agreement  terminates  automatically if it is assigned and may be
terminated  without  penalty  by vote of a  majority  of the  Fund's  shares (as
defined in "Investment  Objectives,  Policies and  Restrictions"),  or by either
party on not more  than 60 days'  nor less than 30 days'  written  notice.  Each
Advisory  Agreement  provides  that if MFS ceases to serve as the Adviser to the
Fund,  the Fund will change its name so as to delete the initials "MFS" and that
MFS may render  services to others and may permit  other fund clients to use the
initials  "MFS" in their names.  Each  Advisory  Agreement  also  provides  that
neither the Adviser nor its personnel  shall be liable for any error of judgment
or mistake of law or for any loss arising out of any  investment  or for any act
or omission in the  execution  and  management  of the Fund,  except for willful
misfeasance,  bad faith or gross  negligence in the  performance of its or their
duties or by reason of reckless disregard of its or their obligations and duties
under the Advisory Agreement.

Administrator

MFS provides the Fund with certain  financial,  legal,  compliance,  shareholder
communications   and  other   administrative   services  pursuant  to  a  Master
Administrative  Services  Agreement dated March 1, 1997, as amended.  Under this
Agreement,  the Fund pays MFS an administrative fee of up to 0.015% per annum of
the Fund's  average daily net assets.  This fee  reimburses MFS for a portion of
the costs it incurs to provide such services.  For the period from March 1, 1997
through August 31, 1997,

                                        22
<PAGE>

MFS received fees under the Administrative Services Agreement as follows:

    Core Growth Fund                        $ 27
    Special Opportunities Fund               276
    Convertible Securities Fund               44
    Blue Chip Fund                            52
    Science and Technology Fund              166

Custodian

State Street Bank and Trust Company (the  "Custodian")  is the custodian of each
Fund's  assets.  The  Custodian's   responsibilities   include  safekeeping  and
controlling  each Fund's cash and securities,  handling the receipt and delivery
of securities,  determining income and collecting interest and dividends on each
Fund's  investments,  maintaining books of original entry for portfolio and fund
accounting and other required books and accounts,  and calculating the daily net
asset  value of each  class of  shares  of each  Fund.  The  Custodian  does not
determine the investment policies of each Fund or decide which securities a Fund
will buy or sell. Each Fund may, however,  invest in securities of the Custodian
and may deal with the  Custodian as principal in  securities  transactions.  The
Custodian also acts as the dividend disbursing agent of each Fund.

Shareholder Servicing Agent

   
MFS Service Center,  Inc. (the "Shareholder  Servicing  Agent"),  a wholly owned
subsidiary  of MFS,  is each Fund's  shareholder  servicing  agent,  pursuant to
Shareholder  Servicing  Agreement  dated  September  10,  1986,  as amended (the
"Agency  Agreement"),   with  the  Trust.  The  Shareholder   Servicing  Agent's
responsibilities under the Agency Agreement include administering and performing
transfer  agent  functions  and the  keeping of records in  connection  with the
issuance,  transfer  and  redemption  of each class of shares of each Fund.  For
these services, the Shareholder Servicing Agent will receive a fee calculated as
a percentage of the average daily net assets of each Fund at an effective annual
rate of 0.1125%. In addition, the Shareholder Servicing Agent will be reimbursed
by each Fund for certain expenses incurred by the Shareholder Servicing Agent on
behalf of the Fund. The Custodian has contracted with the Shareholder  Servicing
Agent to perform certain  dividend and  distribution  disbursing agent functions
for the Fund.
    

Distributor

MFD, a wholly owned  subsidiary of MFS, serves as distributor for the continuous
offering of shares of each Fund pursuant to a  Distribution  Agreement  with the
Trust dated as of January 1, 1995 (the "Distribution Agreement").

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

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

   
MFD allows  discounts  to dealers  (which  are alike for all  dealers)  from the
applicable  public  offering  price of the  Class A  shares.  Dealer  allowances
expressed as a  percentage  of offering  price for all  offering  prices are set
forth in the  Prospectus  (see  "Purchases" in the  Prospectus).  The difference
between the total amount  invested and the sum of (a) the net proceeds to a Fund
and  (b) the  dealer  commission,  is the  commission  paid to the  distributor.
Because of rounding in the  computation  of offering  price,  the portion of the
sales charge paid to the  distributor may vary and the total sales charge may be
more or less than the sales charge  calculated  using the sales charge expressed
as a  percentage  of the  offering  price or as a  percentage  of the net amount
invested as listed in the  Prospectus.  In the case of the maximum sales charge,
the dealer  retains  4.00%  (5.00%  for the Real  Estate  Fund) and MFD  retains
approximately  3/4 of 1% of the public  offering  price.  MFD, on behalf of each
Fund,  pays a  commission  to  dealers  who  initiate  and are  responsible  for
purchases of $1 million or more as described in the Prospectus.
    

Class B Shares,  Class C Shares and Class I Shares: MFD acts as agent in selling
Class B,  Class C shares and Class I shares of each  Fund.  The public  offering
price of Class B,  Class C and  Class I shares is their  net  asset  value  next
computed  after the sale (see  "Purchases"  in the 

                                        23
<PAGE>

Prospectus  and the Prospectus  supplement  pursuant to which Class I shares are
offered).

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

The  Distribution  Agreement will remain in effect until August 1, 1998 and will
continue in effect thereafter only if such continuance is specifically  approved
at least  annually  by the Board of  Trustees  or by vote of a  majority  of the
Trust's shares (as defined in "Investment  Objective,  Policies and Restrictions
- -- Investment  Restrictions")  and in either case, by a majority of the Trustees
who are not parties to the Distribution  Agreement or interested  persons of any
such  party.  The  Distribution  Agreement  terminates  automatically  if  it is
assigned and may be terminated  without penalty by either party on not more than
60 days' nor less than 30 days' notice.

4.       PORTFOLIO TRANSACTIONS AND
         BROKERAGE COMMISSIONS

Specific  decisions  to  purchase or sell  securities  for the Funds are made by
persons affiliated with the Adviser.  Any such person may serve other clients of
the Adviser, or any subsidiary of the Adviser, in a similar capacity. Changes in
each Fund's investments are reviewed by the Board of Trustees.

The  primary   consideration  in  placing  portfolio  security  transactions  is
execution at the most favorable  prices.  The Adviser has complete freedom as to
the markets in and  broker-dealers  through  which it seeks this result.  In the
U.S. and in some other countries debt  securities are traded  principally in the
over-the-counter  market on a net basis  through  dealers  acting  for their own
account and not as brokers.  In other countries both debt and equity  securities
are  traded on  exchanges  at fixed  commission  rates.  The cost of  securities
purchased from underwriters includes an underwriter's  commission or concession,
and the prices at which  securities  are  purchased and sold from and to dealers
include a dealer's  mark-up or  mark-down.  The Adviser  normally  seeks to deal
directly with the primary  market makers or on major  exchanges  unless,  in its
opinion,  better prices are available  elsewhere.  Subject to the requirement of
seeking execution at the best available price,  securities may, as authorized by
the  Advisory  Agreement,  be bought from or sold to dealers who have  furnished
statistical,  research  and other  information  or services to the  Adviser.  At
present no arrangements for the recapture of commission  payments are in effect.
Consistent with the foregoing  primary  consideration,  the Conduct Rules of the
National  Association  of  Securities  Dealers,  Inc.  ("NASD")  and such  other
policies as the Trustees may determine, the Adviser may consider sales of shares
of a Fund and of the other investment  company clients of MFD as a factor in the
selection of broker-dealers to execute the Fund's portfolio transactions.

Under an Advisory  Agreement and as permitted by Section 28(e) of the Securities
Exchange Act of 1934, the Adviser may cause a Fund to pay a broker-dealer  which
provides brokerage and research services to the Adviser, an amount of commission
for  effecting  a  securities  transaction  for the Fund in excess of the amount
other  broker-dealers  would have  charged for the  transaction,  if the Adviser
determines  in good faith that the greater  commission is reasonable in relation
to the value of the  brokerage and research  services  provided by the executing
broker-dealer  viewed  in terms  of  either a  particular  transaction  or their
respective overall  responsibilities to the Fund or to their other clients.  Not
all of such  services  are  useful  or of value  in  advising  a Fund.  The term
"brokerage and research services" includes advice as to the value of securities,
the  advisability  of investing in,  purchasing or selling  securities,  and the
availability of securities or of purchasers or sellers of securities; furnishing
analyses and reports concerning issues, industries, securities, economic factors
and trends,  portfolio  strategy and the performance of accounts;  and effecting
securities  transactions and performing  functions  incidental thereto,  such as
clearance and settlement.

Although  commissions  paid on every  transaction  will,  in the judgment of the
Adviser,  be  reasonable  in  relation  to the value of the  brokerage  services
provided,  commissions  exceeding those which another broker might charge may be
paid to broker-dealers who were selected to execute  transactions on behalf of a
Fund and the  Adviser's  other  clients in part for  providing  advice as to the
availability  of  securities  or of  purchasers  or  sellers of  securities  and
services  in  effecting   securities   transactions  and  performing   functions
incidental thereto, such as clearance and settlement.

Broker-dealers may be willing to furnish statistical, research and other factual
information or services  ("Research") to the Adviser for no consideration  other
than  brokerage or  underwriting  commissions.  Securities may be bought or sold
from time to time through such  broker-dealers on behalf of a Fund. The Trustees
(together with the Trustees of the other MFS Funds) have directed the Adviser to
allocate  a total of $50,980 of  commission  business  from the MFS Funds to the
Pershing Division of Donaldson Lufkin & Jenrette as consideration for the annual
renewal  of  certain  publications  provided  by  Lipper  Analytical  Securities
Corporation (which provides  information useful to the Trustees in reviewing the
relationship  between  a  Fund  and  the  Adviser).   

                                   24
<PAGE>

The Adviser's investment management personnel attempt to evaluate the quality of
Research provided by brokers.  The Adviser sometimes uses evaluations  resulting
from this  effort as a  consideration  in the  selection  of  brokers to execute
portfolio transactions.

The  management  fee of the Adviser will not be reduced as a consequence  of the
Adviser's  receipt of  brokerage  and research  service.  To the extent a Fund's
portfolio  transactions are used to obtain brokerage and research services,  the
brokerage commissions paid by the Fund will exceed those that might otherwise be
paid for such portfolio  transactions,  or for such portfolio  transactions  and
research, by an amount which cannot be presently determined. Such services would
be useful and of value to the Adviser in serving  both a Fund and other  clients
and,  conversely,  such services obtained by the placement of brokerage business
of other clients would be useful to the Adviser in carrying out its  obligations
to the Fund.  While such services are not expected to reduce the expenses of the
Adviser,  the Adviser would,  through use of the services,  avoid the additional
expenses  which  would be incurred  if it should  attempt to develop  comparable
information through its own staff.

For the fiscal year ended August 31, 1996,  the Core Growth Fund and the Special
Opportunities  Fund paid total  brokerage  commissions on total  transactions as
follows:

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

5.       SHAREHOLDER SERVICES

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

                                        25
<PAGE>

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

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

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

         Right of Accumulation:  A shareholder qualifies for cumulative quantity
discounts  on the purchase of Class A shares when his new  investment,  together
with the current  offering  price value of all  holdings of Class A, Class B and
Class C shares of that  shareholder in the MFS Funds or MFS Fixed Fund reaches a
discount  level.  See  "Purchases"  in the  Prospectus  for the sales charges on
quantity  discounts.  For example,  if a shareholder  owns shares with a current
offering  price value of $75,000 and purchases an additional  $25,000 of Class A
shares of a Fund, the sales charge for the $25,000 purchase would be at the rate
of 4.00% (the rate applicable to single transactions of $100,000). A shareholder
must provide the  Shareholder  Servicing  Agent (or his  investment  dealer must
provide MFD) with  information to verify that the quantity sales charge discount
is applicable at the time the investment is made.

         Subsequent  Investment  by  Telephone:  Each  shareholder  may purchase
additional shares of any MFS Fund by telephoning the Shareholder Servicing Agent
toll-free at (800) 225-2606.  The minimum purchase amount is $50 and the maximum
purchase amount is $100,000.  Shareholders  wishing to avail  themselves of this
telephone  purchase  privilege  must so elect on their Account  Application  and
designate  thereon a bank and account number from which  purchases will be made.
If a telephone  purchase request is received by the Shareholder  Servicing agent
on any  business  day  prior to the close of  regular  trading  on the  Exchange
(generally, 4:00 p.m., Eastern time), the purchase will occur at the closing net
asset value of the shares purchased on that day. The Shareholder Servicing Agent
may be liable for any losses resulting from unauthorized  telephone transactions
if it does not follow 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.

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

                                        26
<PAGE>

fund and consider the  differences in objectives and policies  before making any
investment.

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

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

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

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

No  transaction  fee for  exchanges  will be  charged  in  connection  with  the
Automatic Exchange Plan. However,  exchanges of shares of MFS Money Market Fund,
MFS  

                                        27
<PAGE>

Government Money Market Fund and Class A shares of MFS Cash Reserve Fund will be
subject to any  applicable  sales charge.  Changes in amounts to be exchanged to
each  fund,  the  Funds to which  exchanges  are to be made  and the  timing  of
exchanges   (monthly  or  quarterly),   or   termination   of  a   shareholder's
participation in the Automatic  Exchange Plan will be made after instructions in
writing or by  telephone  (an  "Exchange  Change  Request")  are received by the
Shareholder Servicing Agent in proper form (i.e., if in writing -- signed by the
record  owner(s)  exactly as shares are  registered;  if by  telephone -- proper
account  identification  is given by the dealer or shareholder of record).  Each
Exchange Change Request (other than termination of participation in the program)
must involve at least $50. Generally,  if an Exchange Change Request is received
by telephone or in writing before the close of business on the last business day
of a month,  the Exchange  Change  Request will be effective  for the  following
month's exchange.

A shareholder's right to make additional investments in any of the MFS Funds, to
make  exchanges  of shares from one MFS Fund to another and to withdraw  from an
MFS  Fund,  as well as a  shareholder's  other  rights  and  privileges  are not
affected by a shareholder's  participation  in the Automatic  Exchange Plan. The
Automatic  Exchange  Plan is  part of the  Exchange  Privilege.  For  additional
information  regarding the Automatic  Exchange Plan,  including the treatment of
any CDSC, see "Exchange Privilege" below.

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

Exchange  Privilege -- Subject to the requirements set forth below,  some or all
of the shares of the same class in an account with a Fund for which  payment has
been received by the Fund (i.e.,  an  established  account) may be exchanged for
shares of the same  class of any of the other MFS Funds (if  available  for sale
and if  purchaser  is  eligible  to  purchase  the Class of shares) at net asset
value. Exchanges will be made only after instructions in writing or by telephone
(an  "Exchange  Request")  are  received  for  an  established  account  by  the
Shareholder Servicing Agent.

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

No CDSC is imposed on exchanges among the MFS Funds,  although liability for the
CDSC is carried forward to the exchanged shares. For purposes of calculating the
CDSC upon redemption of shares  acquired in an exchange,  the purchase of shares
acquired in one or more  exchanges is deemed to have occurred at the time of the
original purchase of the exchanged shares.

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

Any state income tax advantages for investment in shares of each  state-specific
series of MFS Municipal Series Trust may only benefit  residents of such states.
Investors  should  consult  with  their own tax  advisers  to be sure this is an
appropriate  investment,  based on their  residency and each state's  income tax
laws.  The  exchange  privilege  (or  any  aspect  of  it)  may  be  changed  or
discontinued  and is subject  to certain  limitations  (see  "Purchases"  in the
Prospectus).

Tax-Deferred  Retirement  Plans -- Shares of each Fund may be  purchased  by all
types of tax-deferred  retirement plans. MFD makes available through  investment
dealers plans and/or custody agreements for the following:

   
     Traditional  Individual  Retirement  Accounts (IRAs) (for  individuals who
     desire to make limited  contributions to a Tax-deferred  retirement program
     and, if eligible,  to receive a federal  Income tax  deduction  for amounts
     contributed);
     Roth  Individual  Retirement  Accounts  (Roth IRAs) (for  individuals  who
     desire to make limited contributions to a tax-favored retirement program);
    
     Simplified Employee Pension (SEP-IRA) Plans;
     Retirement  Plans Qualified  under Section 401(k) of the Internal  Revenue
     Code of 1986, as amended (the "Code"); 403(b) Plans (deferred compensation
     arrangements for employees of public School systems and certain non-profit
     organizations); and
     Certain other qualified pension and profit-sharing plans.

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

An investor should consult with his tax adviser before  establishing  any of the
tax-deferred retirement plans described above.

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

6.       TAX STATUS

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

Shareholders of each Fund normally will have to pay federal income taxes and any
state or local  taxes on the  dividends  and  capital  gain  distributions  they
receive from the Fund. Dividends from ordinary income and any distributions from
net short-term  capital gains are taxable to shareholders as ordinary income for
federal  income tax  purposes,  whether  the  distributions  are paid in cash or
reinvested  in  additional  shares.  A portion of each  Fund's  ordinary  income
dividends  is  normally  eligible  for  the   dividend-received   deduction  for
corporations  if the  recipient  otherwise  qualifies  for that  deduction  with
respect  to its  holding  of Fund  shares.  Availability  of the  deduction  for
particular  corporate  shareholders  is  subject  to  certain  limitations,  and
deducted amounts may be subject to the alternative minimum tax and any result in
certain basis adjustments.  Distributions of net capital gains (i.e., the excess
of net long-term capital gains over net short-term 

                                        29
<PAGE>

capital losses),  whether paid in cash or reinvested in additional  shares,  are
taxable to a Fund's  shareholders as long-term  capital gains for federal income
tax purposes without regard to the length of time  shareholders  have held their
shares.  Such capital gains may be taxable to shareholders that are individuals,
estates or trusts at maximum  rates of 20%, 25% or 28%,  depending on the source
of the gain. Any Fund dividend that is declared in October, November or December
of any calendar year, that is payable to shareholders of record in such a month,
and that is paid the  following  January  will be treated as if  received by the
shareholders on December 31 of the year in which the dividend is declared.  Each
Fund  will  notify  shareholders   regarding  the  federal  tax  status  of  its
distributions after the end of each calendar year.

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

   
In general,  any gain or loss realized upon a taxable disposition of shares of a
Fund by a shareholder  that holds such shares as a capital asset will be treated
as a long-term  capital  gain or loss if the shares have been held for more than
twelve  months and  otherwise as a short-term  capital gain or loss; a long-term
capital  gain  realized by an  individual,  estate or trust may be eligible  for
reduced tax rates if the shares were held for more than 18 months.  However, any
loss realized upon a disposition of shares in a Fund held for six months or less
will be treated as a long-term  capital loss to the extent of any  distributions
of net capital gain made with respect to those shares.  Any loss realized upon a
disposition of shares may also be disallowed under rules relating to wash sales.
Gain may be increased (or loss reduced) upon a redemption of Class A shares of a
Fund within 90 days after their  purchase  followed by any  purchase  (including
purchases by exchange or by reinvestment) without payment of an additional sales
charge  of Class A shares  of that  Fund or of  another  MFS Fund (or any  other
shares of an MFS Fund generally sold subject to a sales charge).
    

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

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

Special tax considerations  apply with respect to foreign investments of a Fund.
Foreign exchange gains or losses realized by a Fund will generally be treated as
ordinary income or losses.  Use of foreign  currencies for non-hedging  purposes
and investment by a Fund in certain "passive foreign  investment  companies" may
be limited in order to avoid  imposition  of a tax on the Fund. A Fund may elect
to mark-to-market any investments in "passive foreign  investment  companies" on
the last day of each year. This election may cause the Fund to recognize  income
prior to the receipt of cash  payments  with  respect to those  investments;  in
order to  distribute  this  income and avoid a tax on the Fund,  the Fund may be
required  to  liquidate  portfolio  securities  that  it  might  otherwise  have
continued to hold.

Investment  income received by a Fund from foreign  securities may be subject to
foreign income taxes withheld at the source;  the Funds do not expect to be able
to pass  through to their  shareholders  foreign  tax  credits  with  respect to
foreign  income taxes paid by the Funds.  The United States has entered into tax
treaties with many foreign  countries  that may entitle a Fund to a reduced rate
of tax or an exemption from tax on such income; each Fund intends to qualify for
treaty reduced rates where available. It is not possible,  however, to determine
a Fund's effective rate of foreign tax in advance since the amount of the 

                                        30
<PAGE>

Fund's assets to be invested within various countries is not known.

   
Dividends  and  certain  other  payments  to  persons  who are not  citizens  or
residents  of the  United  States  or U.S.  entities  ("Non-U.S.  Persons")  are
generally  subject to U.S. tax withholding at the rate of 30%. Each Fund intends
to  withhold  U.S.  federal  income  tax at the rate of 30% (or any  lower  rate
permitted under an applicable treaty) on taxable dividends and other payments to
Non-U.S. Persons that are subject to such withholding.  Any amounts overwithheld
may be  recovered  by such  persons by filing a claim for  refund  with the U.S.
Internal  Revenue  Service  within the time period  appropriate  to such claims.
Distributions  received  from a Fund by Non-U.S.  Persons may also be subject to
tax under the laws of their own  jurisdictions.  Each Fund is also  required  in
certain  circumstances to apply backup withholding at the rate of 31% on taxable
dividends and redemption proceeds paid to any shareholder  (including a Non-U.S.
Person) who does not furnish to the Fund certain  information and certifications
or who is otherwise subject to backup withholding.  Backup withholding will not,
however,  be  applied to  payments  that have been  subject to 30%  withholding.
Although each Fund intends to conduct its investments so as not to be classified
as a United States real property  holding  corporation,  it is possible that the
Real  Estate  Fund  could be so  classified.  If the Real  Estate  Fund  were so
classified  at any time,  it would  generally be required to withhold 10% of the
gross proceeds of any  redemption or exchange of shares of the Fund,  unless the
shareholder  provided acceptable  certification of U.S. Person status or of same
other exception from withholding.
    

A Fund will not be required to pay Massachusetts  income or excise taxes as long
as it qualifies as a regulated investment company under the Code.

7.       DISTRIBUTION PLAN

The Trustees have adopted a Distribution  Plan for each Fund (the  "Distribution
Plan") 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
Distribution  Plan  would  benefit  each  Fund  and  each  respective  class  of
shareholders. The provisions of the Distribution Plan are severable with respect
to each Class of shares offered by each Fund. The Distribution  Plan is designed
to promote  sales,  thereby  increasing  the net  assets of each  Fund.  Such an
increase  may reduce the  expense  ratio to the extent a Fund's  fixed costs are
spread over a larger net asset base.  Also, an increase in net assets may lessen
the adverse effect that could result were a Fund required to liquidate portfolio
securities to meet  redemptions.  There is,  however,  no assurance that the net
assets of a Fund will increase or that the other benefits referred to above will
be realized.  The  Distribution  Plan is described in the  Prospectus  under the
caption  "Distribution  Plan," which is  incorporated  herein by reference.  The
following information supplements this Prospectus discussion.

SERVICE FEES: With respect to Class A shares,  no service fees will be paid: (i)
to any dealer who is the holder or dealer or record for  investors who own Class
A shares having an aggregate net asset value less than  $750,000,  or such other
amount as may be determined  from time to time by MFD (MFD,  however,  may waive
this minimum  amount  requirement  from time to time);  or (ii) to any insurance
company  which has entered into an agreement  with the Fund and MFD that permits
such insurance company to purchase Class A shares from a Fund at their net asset
value in  connection  with  annuity  agreements  issued in  connection  with the
insurance company's separate accounts. Dealers may from time to time be required
to meet certain other criteria in order to receive service fees.

With  respect to Class B shares,  except in the case of the first  year  service
fee, no service fees will be paid to any securities  dealer who is the holder or
dealer of record for  investors  who own Class B shares  having an aggregate net
asset value of less than  $750,000 or such other amount as may be  determined by
MFD from time to time. MFD, however,  may waive this minimum amount  requirement
from time to time.  Dealers may from time to time be  required  to meet  certain
other criteria in order to receive service fees.

MFD or its affiliates shall be entitled to receive any service fee payable under
the  Distribution  Plan for  which  there is no  dealer  of  record or for which
qualification  standards have not been met as partial consideration for personal
services and/or account maintenance  services performed by MFD or its affiliates
for shareholder accounts.

DISTRIBUTION  FEES:  The  purpose  of  distribution  payments  to MFD  under the
Distribution Plan is to compensate MFD for its distribution  services to a Fund.
MFD pays commissions to dealers as well as expenses of printing prospectuses and
reports used for sales  purposes,  expenses with respect to the  preparation and
printing of sales literature and other distribution related expenses, including,
without limitation, the cost necessary to provide distribution-related services,
or personnel, travel, office expense and equipment.

During the period from the commencement of operations,  to the fiscal year ended
August 31, 1997,  distribution and service fees under the Distribution Plan were
not imposed.

GENERAL:  The Distribution  Plan will remain in effect until August 1, 1998, and
will continue in effect  thereafter  only if such  continuance  is  specifically
approved at least  annually by vote of both the  Trustees  and a majority of the

                                        31
<PAGE>
Trustees who are not "interested  persons" or financially  interested parties of
such Plan ("Distribution Plan Qualified  Trustees").  The Distribution Plan also
requires that the Fund and MFD each shall provide the Trustees, and the Trustees
shall review, at least quarterly,  a written report of the amounts expended (and
purposes  therefor) under such Plan. The Distribution  Plan may be terminated at
any time by vote of a majority of the Distribution Plan Qualified Trustees or by
vote of the holders of a majority of the  respective  class of the Fund's shares
(as defined in "Investment Restrictions"). All agreements relating to any of the
Distribution  Plan entered into between the Fund or MFD and other  organizations
must  be  approved  by the  Board  of  Trustees,  including  a  majority  of the
Distribution  Plan Qualified  Trustees.  Agreements under the Distribution  Plan
must be in writing,  will be terminated  automatically  if assigned,  and may be
terminated at any time without payment of any penalty,  by vote of a majority of
the Distribution Plan Qualified Trustees or by vote of the holders of a majority
of the respective  class of a Fund's shares.  The  Distribution  Plan may not be
amended to increase  materially  the amount of permitted  distribution  expenses
without the approval of a majority of the respective  class of the Fund's shares
(as defined in "Investment  Restrictions")  or may not be materially  amended in
any case without a vote of the Trustees and a majority of the Distribution  Plan
Qualified Trustees.  The selection and nomination of Distribution Plan Qualified
Trustees  shall be committed to the  discretion of the  non-interested  Trustees
then in office.  No Trustee who is not an "interested  person" has any financial
interest in the Distribution Plan or in any related agreement.

8.       DETERMINATION OF NET ASSET VALUE AND PERFORMANCE

Net Asset  Value:  The net asset  value per share of each  class of each Fund is
determined  each day during which the  Exchange is open for trading.  (As of the
date of this SAI, the Exchange is open for trading every weekday  except for the
following  holidays  (or the days on which they are  observed):  New Year's Day,
Presidents' Day, Martin Luther King Day, Good Friday, Memorial Day, Independence
Day, Labor Day,  Thanksgiving Day and Christmas Day.) This determination is made
once each day as of the close of regular  trading on the  Exchange by  deducting
the amount of the  liabilities  attributable  to the class from the value of the
assets  attributable  to the class and dividing the  difference by the number of
shares of the class  outstanding.  Equity  securities in a Fund's  portfolio are
valued at the last sale price on the exchange on which they are primarily traded
or on the Nasdaq stock market for unlisted  national  market  issues,  or at the
last quoted bid price for listed  securities in which there were no sales during
the day or for unlisted  securities  not  reported on the Nasdaq  stock  market.
Bonds and other fixed income securities  (other than short-term  obligations) of
U.S.  issuers  in a Fund's  portfolio  are  valued  on the  basis of  valuations
furnished by a pricing  service which utilizes both  dealer-supplied  valuations
and electronic data processing  techniques  which take into account  appropriate
factors  such as  institutional-size  trading in similar  groups of  securities,
yield, quality,  coupon rate, maturity,  type of issue, trading  characteristics
and other market data without exclusive  reliance upon quoted prices or exchange
or over-the-counter  prices,  since such valuations are believed to reflect more
accurately the fair value of such securities.  Forward  Contracts will be valued
using a pricing  model  taking into  consideration  market data from an external
pricing  source.  Use of the pricing  services has been approved by the Board of
Trustees.  All other  securities,  futures  contracts  and  options  in a Fund's
portfolio (other than short-term  obligations) for which the principal market is
one or more securities or commodities  exchanges  (whether  domestic or foreign)
will be valued at the last reported sale price or at the settlement  price prior
to the  determination  (or if there has been no current sale, at the closing bid
price) on the primary  exchange on which such securities,  futures  contracts or
options are traded; but if a securities exchange is not the principal market for
securities, such securities will, if market quotations are readily available, be
valued at current bid prices,  unless such securities are reported on the Nasdaq
stock  market,  in which  case they are  valued at the last sale price or, if no
sales  occurred  during  the  day,  at the last  quoted  bid  price.  Short-term
obligations  in  a  Fund's   portfolio  are  valued  at  amortized  cost,  which
constitutes  fair  value as  determined  by the  Board of  Trustees.  Short-term
obligations  with a remaining  maturity in excess of 60 days will be valued upon
dealer supplied  valuations.  Portfolio  investments for which there are no such
quotations or valuations are valued at fair value as determined in good faith by
or at the direction of the Board of Trustees.

Generally,  trading in foreign securities is substantially completed each day at
various  times  prior  to  the  close  of  regular   trading  on  the  Exchange.
Occasionally,  events  affecting the values of such securities may occur between
the times at which they are determined  and the close of regular  trading on the
Exchange  which will not be reflected in the  computation  of a Fund's net asset
value unless the Trustees deem that such event would  materially  affect the net
asset value in which case an adjustment would be made.

All  investments  and assets are  expressed in U.S.  dollars  based upon current
currency  exchange  rates.  A share's  net asset value is  effective  for orders
received by the dealer prior to its calculation and received by MFD prior to the
close of that business day.

PERFORMANCE INFORMATION

   
Total Rate of Return: Each Fund will calculate its total rate of return for each
class of shares for certain periods by 
    
                                        32
<PAGE>
   

determining  the average  annual  compounded  rates of return over those periods
that would cause an investment of $1,000 (made with all distributions reinvested
and reflecting the CDSC or the maximum public offering price) to reach the value
of that investment at the end of the periods. Each Fund may also calculate (i) a
total rate of return,  which is not  reduced by the CDSC (4% maximum for Class B
shares and 1% maximum for Class C shares) and  therefore  may result in a higher
rate of return, (ii) a total rate of return assuming an initial account value of
$1,000,  which  will  result in a higher  rate of return  since the value of the
initial  account will not be reduced by the sales charge  (4.75%  (5.75% for the
Real Estate Fund)  maximum with respect to Class A shares)  and/or (iii) a total
rate  of  return  which  represents  aggregate  performance  over  a  period  or
year-by-year  performance,  and which may or may not  reflect  the effect of the
maximum or other sales charge or CDSC.

Each Fund offers  multiple  classes of shares which were  initially  offered for
sale to, and purchased by, the public on different  dates (the class  "inception
date").  The calculation of total rate of return for a class of shares which has
a later  inception  date than another class of shares of a Fund is based both on
(i) the  performance  of the Fund's newer class from its inception date and (ii)
the  performance  of the Fund's oldest class from its  inception  date up to the
class inception date of the newer class.

As discussed in the Prospectus,  the sales charges, expenses and expense ratios,
and  therefore  the  performance,  of a Fund's  classes  of  shares  differ.  In
calculating  total rate of return for a newer class of shares in accordance with
certain  formulas  required by the SEC, the performance will be adjusted to take
into  account  the fact that the newer  class is  subject to a  different  sales
charge than the oldest  class (e.g.,  if the newer class is Class A shares,  the
total rate of return  quoted will  reflect the  deduction  of the initial  sales
charge applicable to Class A shares;  if the newer class is Class B shares,  the
total rate of return quoted will reflect the deduction of the CDSC applicable to
Class B shares).  However,  the  performance  will not be  adjusted to take into
account the fact that the newer class of shares bears  different  class specific
expenses than the oldest shares (e.g.,  Rule 12b-1 fees).  Therefore,  the total
rate of return  quoted for a newer  class of shares  will differ from the return
that  would be quoted had the newer  class of shares  been  outstanding  for the
entire  period  over which the  calculation  is based  (i.e.,  the total rate of
return quoted for the newer class will be higher than the return that would have
been quoted had the newer class of shares been outstanding for the entire period
over which the calculation is based if the class specific expenses for the newer
class are higher than the class specific  expenses of the oldest class,  and the
total rate of return  quoted  for the newer  class will be lower than the return
that would be quoted had the newer  class of shares  been  outstanding  for this
entire period if the class specific  expenses for the newer class are lower than
the class specific expenses of the oldest class).
    

Total  rate of return  quotations  for each Fund are  presented  in  Appendix  A
attached hereto under the heading "Performance Quotations."

Total rate of return figures would have been lower if fee reductions were not in
place.  These figures are not calculated on an annualized  basis.  The aggregate
total return represents a limited time frame and may not be indicative of future
performance.

   
Yield:  Any  yield  quotation  for a class of  shares  of a Fund is based on the
annualized net investment  income per share of that class for the 30-day period.
The  yield  for  each  class  of the  Fund is  calculated  by  dividing  the net
investment  income  allocated  to that  class  earned  during  the period by the
maximum  offering  price per share of that  class of the Fund on the last day of
the period.  The resulting figure is then annualized.  Net investment income per
share of a class is  determined  by  dividing  (i) the  dividends  and  interest
allocated to that class during the period,  minus accrued  expense of that class
for the period by (ii) the  average  number of shares of the class  entitled  to
receive dividends during the period multiplied by the maximum offering price per
share on the last day of the  period.  The Fund's  yield  calculations  assume a
maximum  sales  charge of 4.75%  (5.75% for the Real Estate Fund) in the case of
Class A shares  and no  payment  of any CDSC in the case of Class B and  Class C
shares.  Yield  quotations  for each Fund are  presented  in Appendix A attached
hereto under the heading "Performance Quotations."

Current  Distribution  Rate: Yield,  which is calculated  according to a formula
prescribed  by the SEC, is not  indicative  of the amounts which were or will be
paid to a Fund's  shareholders.  Amounts paid to  shareholders of each class are
reflected in the quoted "current  distribution rate" for that class. The current
distribution  rate for a class is  computed  by  dividing  the  total  amount of
dividends  per share paid by the Fund to  shareholders  of that class during the
past 12 months by the maximum public  offering price of that class at the end of
such period. Under certain  circumstances,  such as when there has been a change
in the  amount  of  dividend  payout,  or a  fundamental  change  in  investment
policies,  it might be  appropriate  to annualize  the  dividends  paid over the
period such policies were in effect,  rather than using the dividends during the
past 12 months. The current distribution rate differs from the yield computation
because it may include  distributions  to  shareholders  from sources other than
dividends and interest,  such as premium income from option writing,  short-term
capital gains and return of invested capital, and is calculated over a different
period of time.  A Fund's  current  distribution  rate  calculation  for Class A
shares assumes a maximum sales charge of 4.75% (5.75% for the Real Estate 
    
                                        33
<PAGE>
   

Fund). The Fund's current  distribution rate calculation for Class B and Class C
shares assumes no CDSC is paid.  Current  distribution  rate quotations for each
Fund are presented in Appendix A attached hereto under the heading  "Performance
Quotations."
    

General: From time to time each Fund may, as appropriate, quote Fund rankings or
reprint  all or a portion of  evaluations  of fund  performance  and  operations
appearing in various independent publications,  including but not limited to the
following:  Money,  Fortune,  U.S. News and World Report,  Kiplinger's  Personal
Finance, The Wall Street Journal, Barron's,  Investors Business Daily, Newsweek,
Financial World, Financial Planning, Investment Advisor, USA Today, Pensions and
Investments,  SmartMoney,  Forbes,  Global Finance,  Registered  Representative,
Institutional  Investor,  the Investment  Company  Institute,  Johnson's Charts,

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

From time to time, each Fund may discuss or quote its current  portfolio manager
as well as other  investment  personnel,  including  such persons' views on: the
economy;  securities markets; portfolio securities and their issuers; investment
philosophies,  strategies,  techniques  and  criteria  used in the  selection of
securities to be purchased or sold for the Fund; the Fund's portfolio  holdings;
the investment research and analysis process;  the formulation and evaluation of
investment  recommendations;  and  the  assessment  and  evaluation  of  credit,
interest rate, market and economic risks, and similar or related matters.

The Fund may also quote evaluations mentioned in independent radio or television
broadcasts.

From time to time the Fund may use  charts  and  graphs to  illustrate  the past
performance of various indices such as those  mentioned above and  illustrations
using  hypothetical rates of return to illustrate the effects of compounding and
tax-deferral.

From  time to time  the  Fund  may  also  discuss  or  quote  the  views  of its
distributor,  its investment adviser and other financial  planning,  legal, tax,
accounting, insurance, estate planning and other professionals, or from surveys,
regarding  individual  and family  financial  planning.  Such views may  include
information regarding:  retirement planning;  tax management strategies;  estate
planning;  general investment techniques (e.g., asset allocation and disciplined
saving and  investing);  business  succession;  ideas and  information  provided
through the MFS Heritage  Planningsm  program,  an  intergenerational  financial
planning assistance program;  issues with respect to insurance (e.g., disability
and life  insurance  and  Medicare  supplemental  insurance);  issues  regarding
financial  and health care  management  for elderly  family  members;  and other
similar or related matters.

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

9.       DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES

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

Shareholders  are  entitled  to one vote for each share held and may vote in the
election of Trustees and on other matters submitted to meetings of shareholders.
Although Trustees are not elected annually by the shareholders,  the Declaration
of Trust  provides  that a Trustee  may be removed  from  office at a meeting of
shareholders by a vote of two-thirds of the  outstanding  shares of the Trust. A
meeting of  shareholders  will be called  upon the  request of  shareholders  of
record  holding in the  aggregate  not less than 10% of the  outstanding  voting
securities of the Trust. No material amendment may be made to the Declaration of
Trust  without the  affirmative  vote of a majority  of the Trust's  outstanding
shares (as defined in "Investment Restrictions"). The Trust or any series of the
Trust may be terminated (i) upon the merger or consolidation of the Trust or any
series  of the  Trust  with  another  organization  or upon  the  sale of all or
substantially  all of its  assets  (or all or  substantially  all of the  assets
belonging to any series of the Trust), if approved by the vote of the holders of
two-thirds of the Trust's or the affected series' outstanding shares voting as a
single  class,  or of the  affected  series  of the  Trust,  except  that if the
Trustees  recommend such merger,  consolidation or sale, the approval by vote of
the  holders of a majority of the Trust's or the  affected  series'  outstanding
shares will be sufficient,  or (ii) upon  liquidation  and  distribution  of the
assets of a Fund,  if approved by the vote of the holders of  two-thirds  of its
outstanding  shares of the Trust,  or (iii) by the Trustees by written notice to
its shareholders. If not so terminated, the Trust will continue indefinitely.

The Trust is an entity of the type commonly known as a  "Massachusetts  business
trust." Under Massachusetts law, shareholders of such a trust may, under certain
circumstances,  be held  personally  liable  as  partners  for its  obligations.
However,  the Declaration of Trust contains an express disclaimer of shareholder
liability for acts or obligations of the Trust and provides for  indemnification
and  reimbursement  of expenses out of Trust property for any  shareholder  held
personally  liable for the  obligations of the Trust.  The  Declaration of Trust
also provides that the Trust shall maintain appropriate  insurance (for example,

                                        35
<PAGE>
fidelity  bonding and errors and omissions  insurance) for the protection of the
Trust and its shareholders and the Trustees,  officers,  employees and agents of
the Trust  covering  possible tort and other  liabilities.  Thus,  the risk of a
shareholder  incurring  financial  loss on account of  shareholder  liability is
limited to  circumstances  in which both  inadequate  insurance  existed and the
Trust itself was unable to meet its obligations.

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

(1) Total rate of return  figures  would have been lower if certain  fee waivers
were not in place.  
(2) From inception of Class A shares on January 2, 1996. 
(3) Class I share performance  includes the performance of the Fund's Class A 
shares for the periods prior to the inception of Class I shares on January 2, 
1997. Sales charges, expenses and expense ratios, and therefore  performance for
Class I and A shares differ.  Class I share  performance has been adjusted to 
reflect that Class I shares are not  subject  to an  initial  sales  charge,  
whereas  Class  A  shares generally are subject to an initial sales charge. 
Class I share performance has not,  however,  been  adjusted  to  reflect  
differences  in  operating expenses  (e.g.,  Rule 12b-1 fees),  which generally 
are lower for Class I shares.

this Part C, or otherwise,  the  Registrant has been advised that in the opinion
of the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is,  therefore,  unenforceable.  In the event
that a claim  for  indemnification  against  such  liabilities  (other  than the
payment by the Registrant of expenses incurred or paid by a trustee,  officer or
controlling  person of the Registrant in the  successful  defense of any action,
suit or proceeding) is asserted by such director,  officer or controlling person
in connection with the Securities being registered,  the Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

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

         Pursuant to Section 6.9(h) of the Declaration, this instrument shall be

Real Estate Investment Fund to create four classes of Shares, within the meaning
of Section 6.10, as follows:

          1.   The four  classes  of Shares  are  designated  "Class A  Shares,"
               "Class B Shares," "Class C Shares" and "Class I Shares";

          2.   Class A Shares, Class B Shares, Class C Shares and Class I Shares
               shall be entitled to all the rights and  preferences  accorded to
               shares under the Declaration;

               Trustees  of the Trust in  accordance  with the  Declaration  and
               shall be set forth in the current  prospectus  and  statement  of
               additional  information  of the Trust or any series  thereof,  as
               amended from time to time,  contained in the Trust's registration
               statement  under the Securities Act of 1933, as amended,  and the
               Investment Company Act of 1940, as amended;
<PAGE>

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

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


<PAGE>

executed this amendment, in one or more counterparts,  all constituting a single
instrument, as an instrument under seal in The Commonwealth of Massachusetts, as

                    FORM OF INVESTMENT ADVISORY AGREEMENT




         INVESTMENT ADVISORY  AGREEMENT,  dated this 17th day of March, 1998, by
and between MFS SERIES TRUST I, a Massachusetts business trust (the "Trust"), on
behalf of MFS REAL ESTATE  INVESTMENT  FUND, a series of the Trust (the "Fund"),
and  MASSACHUSETTS  FINANCIAL  SERVICES  COMPANY,  a Delaware  corporation  (the
"Adviser").

                                  WITNESSETH:

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

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

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

     Article 1. Duties of the Adviser.  The Adviser  shall provide the Fund with
such  investment  advice  and  supervision  as the  latter may from time to time
consider  necessary for the proper  supervision of its funds.  The Adviser shall
act as Adviser to the Fund and as such shall furnish  continuously an investment
program  and  shall  determine  from  time  to time  what  securities  shall  be
purchased, sold or exchanged and what portion of the assets of the Fund shall be
held  uninvested,  subject always to the restrictions of the Trust's Amended and
Restated  Declaration of Trust,  dated  December 14, 1994, and By-Laws,  each as
amended from time to time  (respectively,  the "Declaration" and the "By-Laws"),
to  the  provisions  of the  Investment  Company  Act of  1940  and  the  Rules,
Regulations and orders thereunder and to the Fund's then-current  Prospectus and
Statement of Additional Information. The Adviser shall also make recommendations
as to the manner in which voting rights,  rights to consent to corporate  action
and any other rights  pertaining  to the Fund's  portfolio  securities  shall be
exercised.  Should  the  Trustees  at  any  time,  however,  make  any  definite
determination  as to the  investment  policy and notify the  Adviser  thereof in
writing,  the Adviser shall be bound by such  determination  for the period,  if
any,   specified  in  such  notice  or  until   similarly   notified  that  such
determination  shall be revoked.  The Adviser shall take, on behalf of the Fund,
all actions  which it deems  necessary  to  implement  the  investment  policies
determined  as provided  above,  and in  particular  to place all orders for the
purchase or sale of portfolio  securities for the Fund's account with brokers or
dealers  selected by it, and to that end, the Adviser is authorized as the agent
of the  Fund  to  give  instructions  to the  Custodian  of the  Fund  as to the
deliveries  of  securities  and payments of cash for the account of the Fund. In
connection with the selection of such brokers or dealers and the placing of such
orders,  the  Adviser is  directed  to seek for the Fund  execution  at the most

                                        1

<PAGE>

reasonable  price  by  responsible  brokerage  firms at  reasonably  competitive
commission  rates.  In  fulfilling  this  requirement,  the Adviser shall not be
deemed to have acted  unlawfully or to have  breached any duty,  created by this
Agreement or otherwise,  solely by reason of its having caused the Fund to pay a
broker or dealer an amount of commission for effecting a securities  transaction
in excess of the  amount  of  commission  another  broker or dealer  would  have
charged for effecting that transaction,  if the Adviser determined in good faith
that such amount of  commission  was  reasonable in relation to the value of the
brokerage  and research  services  provided by such broker or dealer,  viewed in
terms  of  either  that   particular   transaction  or  the  Adviser's   overall
responsibilities with respect to the Fund and to other clients of the Adviser as
to which the Adviser exercises investment discretion.

The Adviser may from time to time enter into sub-investment  advisory agreements
with one or more  investment  advisers  with such  terms and  conditions  as the
Adviser may determine,  provided that such  sub-investment  advisory  agreements
have been approved in accordance  with  applicable  provisions of the Investment
Company Act of 1940.  Subject to the  provisions of Article 6, the Adviser shall
not be liable for any error of judgment or mistake of law by any  sub-adviser or
for any loss arising out of any  investment  made by any  sub-adviser or for any
act or omission in the execution and management of the Fund by any sub-adviser.

     Article 2. Allocation of Charges and Expenses. The Adviser shall furnish at
its own expense investment advisory and administrative  services,  office space,
equipment and clerical personnel  necessary for servicing the investments of the
Fund and maintaining its  organization  and investment  advisory  facilities and
executive and  supervisory  personnel for managing the investments and effecting
the portfolio transactions of the Fund. The Adviser shall arrange, if desired by
the Trust,  for  Directors,  officers  and  employees of the Adviser to serve as
Trustees,  officers or agents of the Trust if duly  elected or appointed to such
positions and subject to their individual consent and to any limitations imposed
by law.  It is  understood  that  the  Fund  will  pay  all of its own  expenses
including,  without  limitation,  compensation of Trustees "not affiliated" with
the Adviser;  governmental fees; interest charges; taxes; membership dues in the
Investment  Company  Institute  allocable  to the  Fund;  fees and  expenses  of
independent auditors, of legal counsel, and of any transfer agent,  registrar or
dividend  disbursing  agent of the Fund;  expenses of repurchasing and redeeming
shares and servicing shareholder accounts;  expenses of preparing,  printing and
mailing stock certificates,  shareholder reports,  notices, proxy statements and
reports to governmental  officers and commissions;  brokerage and other expenses
connected  with the execution,  recording and  settlement of portfolio  security
transactions;  insurance  premiums;  fees and expenses of the  custodian for all
services  to the  Fund,  including  safekeeping  of  funds  and  securities  and
maintaining  required books and accounts;  expenses of calculating the net asset
value of shares of the Fund;  expenses of shareholders'  meetings;  and expenses
relating to the issuance,  registration and  qualification of shares of the Fund
and the  preparation,  printing and mailing of  prospectuses  for such  purposes
(except to the extent that any  Distribution  Agreement  to which the Trust is a
party provides that another party is to pay some or all of such expenses).


                                        2
<PAGE>


         Article 3. Compensation of the Adviser. For the services to be rendered
and the  facilities  provided,  the Fund shall pay to the Adviser an  investment
advisory  fee  computed  and paid  annually  at a rate equal 1.00% of the Fund's
average daily net assets.  If the Adviser shall serve for less than the whole of
any period  specified in this Article 3, the compensation to the Adviser will be
prorated.

         Article 4. Special Services.  Should the Trust have occasion to request
the  Adviser  to perform  services  not herein  contemplated  or to request  the
Adviser to arrange  for the  services of others,  the  Adviser  will act for the
Trust on  behalf  of the Fund  upon  request  to the best of its  ability,  with
compensation  for the Adviser's  services to be agreed upon with respect to each
such occasion as it arises.

         Article 5.  Covenants of the Adviser.  The Adviser  agrees that it will
not  deal  with  itself,  or with  the  Trustees  of the  Trust  or the  Trust's
distributor, if any, as principals in making purchases or sales of securities or
other  property  for  the  account  of the  Fund,  except  as  permitted  by the
Investment Company Act of 1940 and the Rules,  Regulations or orders thereunder,
will not take a long or short  position  in the  shares  of the Fund  except  as
permitted by the  Declaration,  and will comply with all other provisions of the
Declaration  and the By-Laws and the  then-current  Prospectus  and Statement of
Additional Information of the Fund relative to the Adviser and its Directors and
officers.

         Article 6.  Limitation  of Liability of the Adviser.  The Adviser shall
not be  liable  for any  error of  judgment  or  mistake  of law or for any loss
arising out of any  investment  or for any act or omission in the  execution and
management  of the Fund,  except  for  willful  misfeasance,  bad faith or gross
negligence in the performance of its duties and obligations  hereunder.  As used
in this Article 6, the term  "Adviser"  shall  include  Directors,  officers and
employees of the Adviser as well as that corporation itself.

         Article 7.  Activities  of the Adviser.  The services of the Adviser to
the Fund are not  deemed  to be  exclusive,  the  Adviser  being  free to render
investment  advisory  and/or  other  services to others.  The Adviser may permit
other fund  clients to use the initials  "MFS" in their  names.  The Fund agrees
that if the Adviser  shall for any reason no longer  serve as the Adviser to the
Fund,  the Fund will change its name so as to delete the  initials  "MFS." It is
understood that the Trustees,  officers and shareholders of the Trust are or may
be or become interested in the Adviser, as Directors,  officers,  employees,  or
otherwise and that  Directors,  officers and employees of the Adviser are or may
become similarly  interested in the Trust, and that the Adviser may be or become
interested in the Fund as a shareholder or otherwise.

         Article 8. Duration,  Termination and Amendment of this Agreement. This
Agreement  shall  become  effective  on the date first  above  written and shall
govern the relations between the parties hereto thereafter,  and shall remain in
force  until  March  17,  2000  on  which  date  it will  terminate  unless  its
continuance  after March 17, 2000 is  "specifically  approved at least annually"
(i) by the  vote  of a  majority  of the  Trustees  of the  Trust  who  are  not
"interested  persons" of the Trust or of the  Adviser at a meeting  specifically
called  for the  purpose  of voting 

                                        3
<PAGE>

on such approval, and (ii) by the Board of Trustees of the Trust, or by "vote of
a majority of the outstanding voting securities" of the Fund.

         This Agreement may be terminated at any time without the payment of any
penalty by the  Trustees  or by "vote of a majority  of the  outstanding  voting
securities" of the Fund, or by the Adviser,  in each case on not more than sixty
days' nor less than  thirty  days'  written  notice  to the  other  party.  This
Agreement shall automatically terminate in the event of its "assignment".

         This  Agreement  may be amended  only if such  amendment is approved by
"vote of a majority of the outstanding voting securities" of the Fund.

         Article  9.  Scope  of  Trust's  Obligations.  A copy  of  the  Trust's
Declaration of Trust is on file with the Secretary of State of The  Commonwealth
of  Massachusetts.  The Adviser  acknowledges that the obligations of or arising
out of  this  Agreement  are  not  binding  upon  any of the  Trust's  trustees,
officers, employees, agents or shareholders individually, but are binding solely
upon the assets and property of the Trust.  If this Agreement is executed by the
Trust  on  behalf  of one or more  series  of the  Trust,  the  Adviser  further
acknowledges  that the assets and  liabilities  of each  series of the Trust are
separate  and  distinct  and  that the  obligations  of or  arising  out of this
Agreement are binding  solely upon the assets or property of the series on whose
behalf the Trust has executed this Agreement.

         Article  10.  Definitions.  The terms  "specifically  approved at least
annually,"  "vote  of  a  majority  of  the  outstanding   voting   securities,"
"assignment,"  "affiliated  person," and "interested  person," when used in this
Agreement,  shall have the respective meanings specified, and shall be construed
in a manner  consistent  with, the Investment  Company Act of 1940 and the Rules
and Regulations promulgated thereunder,  subject, however, to such exemptions as
may be granted by the Securities and Exchange Commission under said Act.

         Article 11. Record Keeping. The Adviser will maintain records in a form
acceptable to the Trust and in compliance  with the rules and regulations of the
Securities  and  Exchange  Commission,  including  but not  limited  to  records
required to be maintained by Section 31(a) of the Investment Company Act of 1940
and the rules  thereunder,  which at all times will be the property of the Trust
and will be available for inspection and use by the Trust.
