- ------------------------------------
(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 "Purchases").

(2)  The Adviser is currently  waiving its right to receive  management fees
     from each Fund except the Aggressive  Growth Fund.  Absent this waiver,
     "Management  Fees" would be 0.75% per annum for every other Fund except
     for the Research International Fund, and 1.00% per annum for that Fund.

(3)  Each  Fund  has  adopted  a  Distribution  Plan for its  Class A shares  in
     accordance  with Rule 12b-1 under the  Investment  Company Act of 1940,  as
     amended   (the   "1940   Act"),   which   provides   that   it   will   pay
     distribution/service  fees  aggregating up to (but not  necessarily all of)
     0.50% per annum of the  average  daily net assets  attributable  to Class A
     shares (see "Distribution Plans").  Distribution and service fees under the
     Class A Distribution  Plan are currently  being waived on a voluntary basis
     and may be imposed at the  discretion  of MFD.  Distribution  expenses paid
     under  this  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.

(4)  Each Fund has adopted  separate  Distribution  Plans for Class B shares and
     Class C shares in  accordance  with Rule  12b-1  under the 1940 Act,  which
     provide that it will pay  distribution/service  fees aggregating up to (but
     not  necessarily  all of) 1.00% per annum of the  average  daily net assets
     attributable  to Class B shares  under  the Class B  Distribution  Plan and
     Class C shares  under the  Class C  Distribution  Plan  (see  "Distribution
     plans").  Distribution  expenses paid under these Plans,  together

                                        - 5 -

     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.

(5)  "Other  Expenses" for the Convertible  Securities Fund, the Blue Chip Fund,
     the New Discovery  Fund, the Science and  Technology  Fund and the Research
     International  Fund are based on  estimates  of  payments to be made during
     each such Fund's current fiscal year. As discussed below in footnote 6, the
     Adviser is bearing  certain  expenses  of each Fund  except the  Aggressive
     Growth  Fund,   subject  to  reimbursement   by  the  Funds.   Absent  this
     arrangement,  "Other Expenses,"  expressed as a percentage of average daily
     net assets, would be as follows:

(6)  The  Adviser  has  agreed  to  bear  expenses  of  each  Fund,  subject  to
     reimbursement  by the  Funds as  described  under  "Information  Concerning
     Shares of the Funds - Expenses." Under this  arrangement,  "Total Operating
     Expenses"  will not exceed,  on an annualized  basis,  1.50% of each of the
     Equity Income Fund's, Core Growth Fund's and Special  Opportunities  Fund's
     average daily net assets with respect to Class A shares, 2.57% of each such
     Fund's  average daily net assets with respect to Class B shares,  and 2.50%
     of each such  Fund's  average  daily net  assets  with  respect  to Class C
     shares,  during the current fiscal year and each fiscal year through August
     31, 2006.  "Total  Operating  Expenses"  will not exceed,  on an annualized
     basis,  1.50%  of each of the  Convertible  Securities  Fund's,  Blue  Chip
     Fund's,  New Discovery  Fund's and Science and  Technology  Fund's  average
     daily net assets with respect to Class A shares,  2.57% of each such Fund's
     average daily net assets with respect to Class B shares,  and 2.50% of each
     such Fund's average daily net assets with respect to Class C shares, during
     the  current  fiscal year and each fiscal  year  through  August 31,  2007.
     "Total Operating  Expenses" will not exceed, on an annualized basis,  1.75%
     of the Research  International Fund's average daily net assets with respect
     to Class A  shares,  2.82% of the  Fund's  average  daily net  assets  with
     respect to Class B shares, and 2.75% of the Fund's average daily net assets
     with  respect to Class C shares,  during the  current  fiscal year and each
     fiscal year through August 31, 2007.  These  arrangements may be changed or
     terminated  by the Adviser at any time.  Absent any fee waivers and expense
     reductions,  "Total  Operating  Expenses,"  expressed  as a  percentage  of
     average daily net assets, would be as follows:

(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."

                                 EXAMPLE OF EXPENSES

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

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

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

2.       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,  which is  non-diversified.  The  Trust  presently
consists of  thirteen  series,  four 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% of the offering price (or a CDSC upon redemption
of 1.00% 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% 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 upon
redemption  of 1.00%  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.

                                        - 8 -
<PAGE>
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.

3.       CONDENSED FINANCIAL INFORMATION

The  following  information  has been audited and should be read in  conjunction
with  the  financial   statements  included  in  the  Funds'  Annual  Report  to
shareholders  which are  incorporated by reference into the SAI in reliance upon
the report of the Funds'  independent  auditors,  given upon their  authority as
experts in accounting and auditing.  The Funds' independent auditors are Ernst &
Young LLP. The Convertible  Securities Fund, Blue Chip Fund, New Discovery Fund,
Science and  Technology  Fund and Research  International  Fund did not commence
investment operations prior to August 31, 1996.

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.

EQUITY INCOME FUND - The Equity Income Fund's  primary  investment  objective is
reasonable income by investing mainly in  income-producing  securities,  and the
secondary investment objective of the Fund is capital appreciation.

Under  normal  market  conditions,  the Fund  invests  at least 65% of its total
assets in income  producing  equity  securities  (see  "Investment  Techniques -
Equity Securities"  below). The Fund seeks to achieve a gross yield that exceeds
that of the S&P 500.  The Fund may also invest up to 35% of its total  assets in
fixed income  securities,  including up to 20% of its net assets in fixed income
securities  rated BB or lower by Standard & Poor's Ratings  Services  ("S&P") or
Fitch  Investors  Service,  Inc.  ("Fitch") 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. See "Additional Risk Factors -
Lower Rated Bonds" below.

Consistent with its investment objectives and policies described above, the Fund
may also invest up to 35% (and  generally  expects to invest between 5% and 25%)
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 "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."

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 "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 "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."

AGGRESSIVE GROWTH FUND - The Aggressive  Growth Fund's  investment  objective is
capital appreciation.

Under normal market conditions, the Fund invests substantially all of its assets
in equity  securities of companies  which the Adviser  believes  offer  superior
prospects for growth (see "Investment Techniques - Equity Securities" below). In
pursuit of its  investment  objective,  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 Adviser will  consider  many factors when  choosing the Fund's  investments,
such  as  economic  and  financial  trends  or the  prospective  acquisition  or
reorganization of a company.  Some of the Fund's  investments may not respond to
market  rallies or  downturns.  While the Fund may buy  securities  that provide
income,  it does not place any  emphasis  on  income,  except  when the  Adviser
believes this income will have a favorable  influence on the  security's  market
value.

Consistent with its investment  objective and policies described above, the Fund
may invest up to 35% (and generally expects to invest between 5% and 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 "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."

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 "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  "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 S&P or Fitch 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 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 "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 "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 high 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.

<PAGE>
         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 or Fitch 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 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 "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 "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
their substantial capitalization, 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 "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."

NEW DISCOVERY FUND - The New Discovery  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  companies  that the
Adviser believes offer superior prospects for growth. Such securities may either
be listed on securities exchanges or traded in the over-the-counter  markets and
may be U.S. or foreign companies.  While companies in which the Fund invests may
be of any size,  such as companies in a  relatively  early stage of  development
that offer the potential for  accelerated  earnings or revenue growth  (emerging
growth  companies),  or  larger or more  established  companies  whose  rates of
earnings growth are expected to accelerate  because of special factors,  such as
rejuvenated management,  new products, or structural changes in the economy, the
Fund will  generally  invest in  companies  with  small  market  capitalizations
relative to companies included in the S&P 500. 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  also  invest  in fixed  income  securities  offering  an
opportunity for capital  appreciation,  including up to 10% of its net assets in
fixed  income  securities  rated  BB or  lower by S&P or Fitch 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 this Prospectus (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 "Investment Techniques - Short Sales" below).

         Consistent with its investment  objective and policies described above,
the Fund may also invest up to 50% (and  generally  expects to invest up to 20%)
of its  net  assets  in  foreign  securities  which  are not  traded  on an U.S.
exchange.

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 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 "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 and Fitch 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
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 "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."

RESEARCH  INTERNATIONAL  FUND - The  Research  International  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  whose  principal  activities are located  outside the U.S. The equity
securities in which the Fund may invest include  securities of more  established
companies which represent  opportunities  for long-term  growth (see "Investment
Techniques - Foreign Growth  Securities"  below). The Fund may also invest up to
25% of  its  net  assets  in  securities  of  companies  located,  or  primarily
conducting  their  business,  in emerging  market  countries.  The  selection of
securities  is made solely on the basis of potential  for capital  appreciation.
The Fund does not intend to emphasize any  particular  country and, under normal
market conditions, will be invested in at least five countries. In addition, the
Fund may hold  foreign  currency  received in  connection  with  investments  in
foreign  securities or in  anticipation  of purchasing  foreign  securities (see
"Additional Risk Factors - Foreign Securities" below.)

         In determining where a company's principal  activities are located, the
Adviser  considers  such factors as its country of  organization,  the principal
trading market for its securities and the source of its revenues and assets. The
company's principal  activities are deemed to be located in a particular country
if: (a) the company is  organized  under the laws of, and  maintains a principal
office in, that country;  (b) the company has its principal  securities  trading
market  in  that  country;  (c) the  company  derives  50% or more of its  total
revenues  from goods sold or  services  performed  in that  country;  or (d) the
company has 50% or more of its assets in that country.

         The  portfolio  securities  of the Fund are  selected by a committee of
investment  research  analysts.  This  committee  includes  investment  analysts
employed not only by the Adviser but also by MFS International (U.K.) Limited, a
wholly owned  subsidiary of MFS, and investment  analysts  employed by Foreign &
Colonial  Management  Limited and Foreign & Colonial  Emerging  Markets Limited,
with which MFS has entered into a strategic  alliance  (see  "Management  of the
Funds" below). The Fund's assets are allocated among countries and industries by
the  analysts  acting  together  as  a  group.   Individual  analysts  are  then
responsible  for selecting what they view as the securities  best suited to meet
the Fund's  investment  objective within their assigned  geographic and industry
responsibility.

         The Fund may engage in certain investment techniques as described under
the caption "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."

5.       INVESTMENT TECHNIQUES

The investment  techniques  described  below are applicable to all or certain of
the  Funds,  as  specified.   Additional  information  about  certain  of  these
investment techniques can be found under the caption "Investment  Techniques" in
the SAI.

INVESTMENT   TECHNIQUES  APPLICABLE  TO  EACH  FUND.  The  following  investment
techniques are applicable to each Fund:

         EQUITY  SECURITIES:  Each  Fund  may  invest  in all  types  of  equity
securities,  including  the  following:  common  stocks,  preferred  stocks  and
preference  stocks;  securities  such as  bonds,  warrants  or  rights  that are
convertible into stocks;  and depository  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").  The Trust's Board of Trustees determines, based upon a continuing
review of the trading  markets for a specific Rule 144A  security,  whether such
security is 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, will retain sufficient oversight and be ultimately  responsible for the
determinations. The Board will carefully monitor each Fund's investments in Rule
144A securities, focusing on such important factors, among others, as valuation,
liquidity and availability of information.  This investment  practice could have
the effect of  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 normally  invest in cash,  cash
equivalents  and high  grade  debt  securities  (if  consistent  with the Fund's
investment policies).

         U.S.  GOVERNMENT  SECURITIES:  The  Equity  Income  Fund,  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

                                        - 14 -
<PAGE>
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 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.

         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 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 "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 the  change  in 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.

         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 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  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.

                                        - 15 -
<PAGE>
         Swap  agreements will tend 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 risks  assumed.
As a result,  swaps can be highly volatile and may have a considerable impact on
a Fund's  performance.  Swap  agreements  are  subject  to risks  related to the
counterparty's   ability  to   perform,   and  may   decline  in  value  if  the
counterparty's  creditworthiness  deteriorates. A Fund may also suffer losses if
it is unable to terminate  outstanding  swap  agreements  or reduce its exposure
through  offsetting  transactions.  Swaps,  caps,  floors and collars are highly
specialized activities which involve certain risks 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. In contrast, however,
if the price of the underlying  security moves adversely to the Fund's position,
the option may be  exercised  and the Fund will be  required to purchase or sell
the underlying security at a disadvantageous  price, which may only be partially
offset by the amount of the premium.  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.

         "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

                                        - 16 -
<PAGE>
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 ("Futures  Contracts") on stock indices, and
may  purchase and sell Futures  Contracts  on foreign  currencies  or indices of
foreign  currencies.  Each  Fund may also  purchase  and write  options  on such
Futures  Contracts.  The Equity Income 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. A Fund will not enter into any Futures Contract if immediately  thereafter
the  value of  securities  and other  obligations  underlying  all such  Futures
Contracts would exceed 50% of the value of its total assets. In addition, a Fund
will not purchase put and call options on Futures  Contracts if as a result more
than 5% of its total assets would be invested in such options.

         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  consistent  with  statements  of the SEC and its  staff
regarding the use of Forward Contracts by registered investment companies, which
requires use of segregated assets or "cover" in connection with the purchase and
sale of such contracts.

         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 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 New  Discovery  Fund or the Science and  Technology  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 exceeds 40% of its net assets.

         MORTGAGE  "DOLLAR  ROLL"  TRANSACTIONS:  The Equity  Income  Fund,  the
Special  Opportunities  Fund and the Convertible  Securities 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 Equity Income Fund, the Special
Opportunities  Fund and the Convertible  Securities 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 Equity
Income Fund, the Special Opportunities Fund and the Convertible  Securities 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 Equity  Income  Fund,  the Special  Opportunities  Fund and the
Convertible  Securities  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  Equity  Income  Fund,  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.  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  Equity  Income  Fund,  the
Special  Opportunities  Fund and the  Convertible  Securities 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  Equity  Income  Fund,  the
Special Opportunities Fund and the Convertible Securities 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.

         MORTGAGE PASS-THROUGH  SECURITIES:  The Equity Income Fund, the Special
Opportunities  Fund and the  Convertible  Securities 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 Equity Income Fund, the Special Opportunities Fund and
the Convertible  Securities 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.

                                        - 19 -
<PAGE>
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, Dominican Republic,  Ecuador,  Jordan, Mexico, Nigeria,  Panama, the
Philippines,  Poland,  Uruguay and Venezuela.  Brady Bonds have been issued only
recently,  and for that reason do not have a long payment  history.  Brady Bonds
may be collateralized or uncollateralized, are issued in various currencies (but
primarily the U.S. dollar) and are actively traded in over-the-counter secondary
markets.  U.S.  dollar-denominated,  collateralized  Brady  Bonds,  which may be
fixed-rate bonds or floating-rate bonds, are generally collateralized in full as
to principal by U.S.  Treasury zero coupon bonds having the same maturity as the
bonds.  Brady  Bonds  are  often  viewed  as  having  three  or  four  valuation
components:  the  collateralized  repayment of principal at final maturity;  the
collateralized  interest payments;  the uncollateralized  interest payments; and
any uncollateralized  repayment of principal at maturity (these uncollateralized
amounts  constituting  the  "residual  risk").  In light of the residual risk of
Brady Bonds and the history of defaults of  countries  issuing  Brady Bonds with
respect to commercial bank loans by public and private entities,  investments in
Brady Bonds may be viewed as speculative.

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 "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 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.

         NON-DIVERSIFICATION:     The    Special     Opportunities    Fund    is
"non-diversified,"  as that term is  defined  in the 1940 Act,  but  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.

                                        - 20 -
<PAGE>
         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 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 Equity Income Fund,  the Special  Opportunities
Fund, the  Convertible  Securities  Fund, the New Discovery Fund and the Science
and  Technology  Fund may invest in fixed income  securities,  and may invest in
convertible  securities,  rated  Baa by  Moody's  or BBB  by  S&P or  Fitch  and
comparable  unrated  securities.  These  securities,  while normally  exhibiting
adequate protection parameters,  have speculative characteristics and changes in
economic conditions or other circumstances are more likely to lead to a weakened
capacity to make  principal  and  interest  payments  than in the case of higher
grade securities.

         These Funds may also invest in securities  rated Ba or lower by Moody's
or BB or lower by S&P or Fitch and comparable unrated securities (commonly known
as "junk bonds") to the extent described above.  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

                                        - 21 -
<PAGE>
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. 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 Rules of Fair
Practice 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 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). 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 Equity
Income Fund, the Core Growth Fund,  the  Aggressive  Growth Fund and the Special
Opportunities  Fund, and December ___, 1996 with respect to the remaining  Funds
(the  "Advisory  Agreements").  The  Adviser  provides  each Fund  with  overall
investment  advisory  and  administrative  services,  as well as general  office
facilities.  Subject to such policies as the Trustees may determine, the Adviser
makes investment  decisions for each Fund. For its services and facilities,  the
Adviser is entitled to receive a management fee,  computed and paid monthly,  in
an amount equal to 0.75% per annum of the average daily net assets of each Fund,
except the Research International Fund, and 1.00% per annum of the average daily
net assets of this Fund.

For the period from the commencement of investment operations,  January 2, 1996,
to the fiscal year end of August 31,  1996,  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 except the  Aggressive  Growth
Fund.

The identity and  background  of the portfolio  manager(s)  for each Fund is set
forth  below.  Each  portfolio  manager  has  acted in that  capacity  since the
commencement of investment operations of each Fund.

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 Union Standard Trust, MFS Institutional  Trust, MFS
Variable Insurance Trust, MFS/Sun Life Series Trust, Sun Growth Variable Annuity
Fund, Inc. and seven variable accounts, each of which is a registered investment
company established by Sun Life Assurance Company of Canada (U.S.) ("Sun Life of
Canada  (U.S.)") in connection with the sale of various  fixed/variable  annuity
contracts.  MFS and its wholly owned  subsidiary,  MFS Asset  Management,  Inc.,
provide investment advice to substantial private clients.

MFS is  America's  oldest  mutual  fund  organization.  MFS and its  predecessor
organizations  have a  history  of money  management  dating  from  1924 and the
founding of the first mutual fund in the U.S.,  Massachusetts  Investors  Trust.
Net assets under the management of the MFS organization were  approximately $___
billion on behalf of approximately  ___ million investor accounts as of November
30, 1996. As of such date,  the MFS  organization  managed  approximately  $____
billion of assets  invested in fixed income  funds and fixed income  portfolios,
approximately  $____  billion  of assets  invested  in foreign  securities,  and
approximately  $____ billion of assets invested in equity  securities.  MFS is a
subsidiary  of Sun  Life of  Canada  (U.S.),  which  in turn is a  wholly  owned
subsidiary of Sun Life Assurance  Company of Canada ("Sun Life").  The Directors
of MFS are A.  Keith  Brodkin,  Jeffrey L.  Shames,  Arnold D. Scott and John D.
McNeil.  Mr. Brodkin is the Chairman,  Mr. Shames is the President and Mr. Scott
is the Secretary and a Senior Executive Vice President of MFS. Mr. McNeil is the
Chairman of Sun Life. Sun Life, a mutual life insurance  company,  is one of the
largest  international  life  insurance  companies and has been operating in the
U.S. since 1895,  establishing a headquarters office here in 1973. The executive
officers of MFS report to the Chairman of Sun Life.

A. Keith  Brodkin,  the  Chairman  and a Director of MFS, is also the  Chairman,
President and a Trustee of the Trust. W. Thomas London,  Stephen E. Cavan, James
O.  Yost and James R.  Bordewick,  Jr.,  all of whom are  officers  of MFS,  are
officers of the Trust.

MFS has established a strategic alliance with Foreign & Colonial Management Ltd.
("FCM").  FCM is a subsidiary of two of the world's  oldest  financial  services
institutions,  the London-based  Foreign & Colonial  Investment Trust PLC, which
pioneered the idea of investment  management in 1868, and HYPO-BANK  (Bayerische
Hypotheken-und  Wechsel-Bank  AG), the oldest  publicly  listed bank in Germany,
founded in 1835. As part of this alliance, the portfolio managers and investment
analysts  of MFS and FCM share  their  views on a variety of  investment-related
issues, such as the economy,  securities markets, portfolio securities and their
issuers, investment  recommendations,  strategies and techniques, risk analysis,
trading strategies and other portfolio management matters. MFS has access to the
extensive  international  equity investment expertise of FCM, and FCM has access
to the extensive U.S. equity investment  expertise of MFS. MFS and FCM each have
investment  personnel  working in each  other's  offices  in Boston and  London,
respectively.

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 or clients of FCM.
Some  simultaneous  transactions  are inevitable  when several  clients  receive
investment  advice  from MFS and FCM,  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.

SUB-INVESTMENT ADVISERS - The Funds' Advisory Agreements permit the Adviser from
time to time to engage one or more  sub-advisers to assist in the performance of
its  services.  The  Adviser  has  engaged  two  sub-advisers  for the  Research

*    Because of rounding in the  calculation  of offering  price,  actual  sales
     charges  may be more or less than those  calculated  using the  percentages
     above.

**   A CDSC will apply to such purchases, as discussed below.

MFD allows  discounts  to dealers  (which  are alike for all  dealers)  from the
applicable  public  offering  price, as shown in the above table. In the case of
the maximum sales charge,  the dealer  retains 4% and MFD retains  approximately
3/4 of 1% of the public offering  price.  The sales charge may vary depending on
the  number of shares of 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.

         PURCHASES  SUBJECT TO A CDSC (but not an initial sales charge).  In the
following  four  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:

     (i)  on investments of $1 million or more in Class A shares;

     (ii) on investments in Class A shares by certain  retirement  plans subject
          to the Employee  Retirement  Income  Security Act of 1974,  as amended
          ("ERISA"),  if:  (a) the  plan had  established  an  account  with the
          Shareholder  Servicing  Agent  prior  to  July  1,  1996  and  (b) the
          sponsoring  organization  demonstrates to the satisfaction of MFD that
          either  (i) the  employer  has at  least  25  employees  or  (ii)  the
          aggregate  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 subject
          to ERISA, if: (a) the retirement plan and/or  sponsoring  organization
          subscribes  to the  MFS  FUNDamental  401(k)  Program  or any  similar
          recordkeeping system made available by the Shareholder Servicing Agent
          (the "MFS 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; and

     (iv) 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, 1996 and (b) 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.  THE RETIREMENT  PLAN
          WILL QUALIFY UNDER THIS  CATEGORY  ONLY IF THE PLAN OR ITS  SPONSORING
          ORGANIZATION  INFORMS  THE  SHAREHOLDER  SERVICING  AGENT PRIOR TO THE
          PURCHASES  THAT  THE  PLAN HAS A  MARKET  VALUE  OF  $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.

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

                                        - 26 -
<PAGE>
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 made on
or after April 1, 1996,  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" 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)
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  or  partially  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" 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 Class B
Distribution Plan (see  "Distribution  Plans" 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).

                                        - 27 -
<PAGE>
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 the Class B  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
or partially  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 the  Distribution  Plan
applicable  to Class B shares.  See  "Distribution  Plans" 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 upon redemption of 1.00% 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 the Class C Distribution  Plan by
the Fund to MFD for the first  year after  purchase  (see  "Distribution  Plans"
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.

                                        - 28 -
<PAGE>
         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.

         RIGHT TO REJECT PURCHASE ORDERS/MARKET TIMING.  Purchases and exchanges
should be made for investment purposes only. Each Fund and MFD reserve the right
to reject any specific  purchase order or to restrict  purchases by a particular
purchaser  (or group of  related  purchasers).  Each  Fund or MFD may  reject or
restrict any  purchases by a particular  purchaser or group,  for example,  when
such purchase is contrary to the best interests of the Fund's other shareholders
or otherwise would disrupt the management of the Fund.

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

         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 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,  payment for travel expenses,  including
lodging,  incurred by registered  representatives  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 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.

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

                                        - 29 -
<PAGE>
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 Fund 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.   Special
procedures,  privileges and restrictions  with respect to exchanges may apply to
market  timers  who  enter  into an  agreement  with  MFD,  as set forth in such
agreement.  See  "Purchases - General - Right to Reject  Purchase  Orders/Market
Timing."

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.

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

                                        - 30 -
<PAGE>
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 B and Class C 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.  Prior to April 1, 1996,  Class C shares of
the MFS Funds were not subject to a CDSC upon redemption. In no event will Class
C shares of the MFS Funds purchased prior to this date be subject to a CDSC. For
the purpose of  calculating  the CDSC upon  redemption of shares  acquired in an
exchange on or after April 1, 1996,  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 (if such original  purchase  occurred prior to April 1,
1996, then no CDSC would be imposed upon such a redemption).

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.

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,  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 PLANS

The Trustees have adopted separate  Distribution  Plans for Class A, Class B and
Class C shares  pursuant  to  Section  12(b)  of the  1940  Act and  Rule  12b-1
thereunder (the  "Distribution  Plans"),  after having concluded that there is a
reasonable  likelihood that the  Distribution  Plans 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 DISTRIBUTION  PLAN: The Distribution  Plans have certain
common features, as described below.

         SERVICE FEES. Each 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 each  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.

         DISTRIBUTION  FEES. Each 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  Plans,  as does  the use by MFD of such  distribution  fees.  Such
amounts  and  uses  are  described  below  in the  discussion  of  the  separate
Distribution Plans. 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  Distribution  Plans have  substantially  identical  provisions with
respect  to their  operating  policies  and  their  initial  approval,  renewal,
amendment and termination.

                                        - 32 -
<PAGE>
FEATURES UNIQUE TO EACH DISTRIBUTION  PLAN: The Distribution  Plans have certain
features that are unique to each class of shares, as described below.

         CLASS  A  DISTRIBUTION  PLAN.  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 Class A Distribution Plan is
equal,  on an  annual  basis,  to 0.25% of a Fund's  average  daily  net  assets
attributable to Class A shares. 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 Class A
Distribution  Plan may be used by MFD to pay  securities  dealers a distribution
fee in an  amount  equal to 0.25%  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% 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  DISTRIBUTION  PLAN.  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 Class B 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  DISTRIBUTION  PLAN.  Class C shares  are  offered at net asset
value without an initial  sales charge but subject to a CDSC upon  redemption of
1.00% 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.

         This ongoing  1.00% fee is comprised of the 0.25% per annum service fee
paid to MFD under  the  Class C  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 Class C 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 under
the Class A 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

                                        - 33 -
<PAGE>
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,
and to make  distributions  to its  shareholders  in accordance  with the timing
requirements  imposed  by the Code.  It is  expected  that the Funds will not be
required  to  pay  entity  level  federal  income  or  excise  taxes,   although
foreign-source  income received by a Fund 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 additional  shares. A portion of
the  dividends  received  from each Fund (but none of the Funds'  capital  gains
distributions)   may   qualify   for  the   dividends-received   deduction   for
corporations. Shortly after the end of each calendar year, each shareholder of a
Fund will be sent a statement  that sets forth the federal  income tax status of
all of the Fund's dividends and distributions for that calendar year,  including
any portion taxable as ordinary income, any portion taxable as long-term capital
gains, the portion, if any, representing a return of capital (which is generally
free of current taxes but results in a basis reduction) and the amount,  if any,
of federal income tax withheld.

Fund distributions will reduce a Fund's net asset value per share.  Shareholders
who buy shares  just  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 a rate of 30% on
dividends and any other payments that are subject to such  withholding  and that
are  made to  persons  who are  neither  citizens  nor  residents  of the  U.S.,
regardless of whether a lower rate may be permitted under an applicable  treaty.
Each Fund is also required in certain  circumstances to apply backup withholding
at a rate  of 31% on  taxable  dividends  and  redemption  proceeds  paid to any
shareholder  (including a shareholder who is neither a citizen nor a resident of
the  U.S.)  who  does  not  furnish  to  the  Fund   certain   information   and
certifications  or who is  otherwise  subject  to backup  withholding.  However,
backup  withholding  will not be applied to payments  which have been subject to
30%   withholding.   Prospective   investors  should  read  the  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 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: 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 discretion of MFS, MFS has agreed to
pay until August 31, 2006 the foregoing  expenses of the Equity Income Fund, the
Core Growth Fund, the Aggressive Growth Fund and the Special  Opportunities Fund
such  that  each  Fund's

                                        - 34 -
<PAGE>
aggregate operating expenses do not exceed, on an annualized basis, 1.50% of the
average  daily net assets with  respect to Class A shares,  2.57% of the average
daily net assets with respect to Class B shares,  and 2.50% of the average daily
net assets with respect to Class C shares.  Such  payments by MFS are subject to
reimbursement by each Fund which will be accomplished by the payment by the Fund
of an expense reimbursement fee to MFS computed and paid monthly as a percentage
of its  average  daily net  assets  for its  then-current  fiscal  year,  with a
limitation that immediately after such payment the aggregate  operating expenses
of a Fund would not  exceed the  above-referenced  percentage  limitations.  The
expense  reimbursement  agreement terminates for each Fund on the earlier of the
date on which  payments  made  thereunder by the Fund equal the prior payment of
such reimbursable expenses by MFS or August 31, 2006.

Subject to  termination  or revision at the discretion of MFS, MFS has agreed to
pay until August 31, 2007 the foregoing  expenses of the Convertible  Securities
Fund,  the Blue Chip Fund,  the New Discovery  Fund,  the Science and Technology
Fund and the  Research  International  Fund  such  that  each  Fund's  aggregate
operating  expenses do not exceed, on an annualized basis,  1.50% (1.75% for the
Research  International  Fund) of the average  daily net assets with  respect to
Class A shares, 2.57% (2.82% for the Research International Fund) of the average
daily net  assets  with  respect  to Class B shares,  and 2.50%  (2.75%  for the
Research  International  Fund) of the average  daily net assets with  respect to
Class C shares.  Such payments by MFS are subject to  reimbursement by each Fund
which  will  be   accomplished  by  the  payment  by  the  Fund  of  an  expense
reimbursement  fee to MFS  computed  and paid  monthly  as a  percentage  of its
average  daily net assets for its  then-current  fiscal year,  with a limitation
that immediately after such payment the aggregate  operating  expenses of a Fund
would not  exceed  the  above-referenced  percentage  limitations.  The  expense
reimbursement  agreement  terminates for each Fund on the earlier of the date on
which  payments  made  thereunder  by the Fund  equal the prior  payment of such
reimbursable expenses by MFS or August 31, 2007.

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 retirement plans established for the benefit of employees of the Adviser
and its affiliates,  entitled Class P shares. As of the date of this Prospectus,
the Trust has  thirteen  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 its  Distribution  Plan or on any other  matter that  affects  solely that
class of shares,  but will  otherwise  vote  together  with all other classes of
shares of the  series on all other  matters.  The Trust  does not intend to hold
annual shareholder  meetings.  The 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"). 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  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 the Lipper
Analytical Services,  Inc., and Wiesenberger Investment Companies Service. Yield
quotations are based on the annualized net investment income per share allocated
to each class of 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

                                        - 36 -
<PAGE>
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
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.  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,  1996,  please see the Funds'
annual report. . The Convertible  Securities Fund, Blue Chip Fund, New Discovery
Fund,  Science  and  Technology  Fund and  Research  International  Fund did not
commence  investment  operations  prior to August 31, 1996. 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 each  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  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.

                                        - 36 -
<PAGE>
         RIGHT OF ACCUMULATION:  A shareholder qualifies for cumulative quantity
discounts on purchases of Class A shares when his new investment,  together with
the current  offering price value of all holdings of any class of shares of that
shareholder  in the MFS Funds or MFS Fixed  Fund (a bank  collective  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 twice monthly,  monthly or quarterly.
Required forms are available from the Shareholder  Servicing Agent or investment
dealers.

         AUTOMATIC  EXCHANGE PLAN:  Shareholders  having account  balances of at
least $5,000 in any MFS Fund may  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 four
different funds. A shareholder  should consider the objectives and policies of a
fund and review its prospectus  before electing to exchange money into such fund
through the Automatic Exchange Plan. No transaction fee is imposed in connection
with exchange transactions under the Automatic Exchange Plan. However, exchanges
of shares of MFS Money Market Fund, MFS Government  Money Market Fund or Class A
shares of MFS Cash Reserve Fund will be subject to any applicable  sales charge.
For federal and (generally) state income tax purposes, an exchange is treated as
a sale of the shares 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,"  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.

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

The Funds' SAI contains more detailed  information  about each Fund,  including,
but not limited to, information  related to: (i) each Fund's investment policies
and  restrictions;  (ii) the  Trustees,  officers and Adviser;  (iii)  portfolio
trading; (iv) the shares, including rights and liabilities of shareholders;  (v)
tax status of dividends and  distributions;  (vi) the  Distribution  Plans;  and
(vii) various  services and privileges  provided by each Fund for the benefit of
its shareholders,  including additional information with respect to the exchange
privilege.

          prior to the  purchase of Class A shares;  and (iv) the MFS Fund,

                          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.

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

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

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

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

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

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

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

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

                                                        S&P

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

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

     A: Debt rated A has a strong  capacity to pay interest and repay  principal
although it is somewhat more  susceptible  to the adverse  effects of changes in

                                        B - 1
<PAGE>
circumstances and economic conditions than debt in higher rated categories.

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

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

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

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

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

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

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

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

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

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

                                     FITCH

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

     AA:  Bonds  considered  to be  investment  grade  and of very  high  credit
quality.  The  obligor's  ability to pay  interest  and repay  principal is very
strong,  although not quite as strong as bonds rated `AAA'.  Because bonds rated
in the `AAA' and `AA' categories are not significantly vulnerable to foreseeable
future developments, short-term debt of these issuers is generally rated `F-1+'.

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

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

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

     B: Bonds are considered highly  speculative.  While bonds in this class are
currently meeting debt service requirements, the probability of continued timely
payment of principal  and  interest  reflects the  obligor's  limited  margin

                                        B - 3
<PAGE>
of safety and the need for reasonable  business and economic activity throughout
the life of the issue.

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

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

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

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

     NR Indicates that Fitch does not rate the specific issue.

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

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

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

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

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," "Investment  Techniques" and "Additional Risk Factors"
sections of the Prospectus.

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 and would
also  receive  compensation  from  the  investment  of the  collateral  (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 holds
through its agent are U.S. Government securities,  the values of 

                                        - 1 -
<PAGE>
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 price 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 margin.

"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 cash,  short-term money market instruments or high quality
debt securities (if consistent with the Fund's investment  policies)  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 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 Equity  Income  Fund,  the  Special
Opportunities  Fund and the Convertible  Securities 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.  During the roll
period,  a Fund  foregoes  principal  and interest  paid on the  mortgage-backed

                                        - 2 -
<PAGE>
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  Equity  Income  Fund,  the  Special
Opportunities  Fund and the Convertible  Securities 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
Equity  Income  Fund,  the  Special   Opportunities  Fund  and  the  Convertible
Securities  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  stripped
securities  and of  investing  in classes  consisting  of  interest  payments or
principal payments.

Each  of the  Equity  Income  Fund,  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  Equity  Income  Fund,  the  Special
Opportunities  Fund and the Convertible  Securities 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

                                        - 3 -
<PAGE>
"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  Equity  Income  Fund,  the  Special
Opportunities  Fund and the  Convertible  Securities 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 cash or other high grade debt  obligations  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"  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  Equity  Income  Fund,  the  Special
Opportunities  Fund and the  Convertible  Securities 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

                                        - 4 -
<PAGE>
("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. 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 Housing and Urban Development.
FNMA purchases  conventional  residential mortgages (I.E., mortgages not insured
or   guaranteed   by  any   governmental   agency)   from  a  list  of  approved
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
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 Equity Income
Fund, the Special  Opportunities  Fund and the  Convertible  Securities 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 New  Discovery  Fund and the  Science and  Technology  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

                                        - 5 -
<PAGE>
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
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 Discovery
Fund and the Science and Technology  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.

No securities will be sold short by a Fund if, after effect is given to any such
short sale, the total market value of all securities sold short would exceed 40%
of the value of the Fund's net assets.

Whenever the Fund engages in short sales, its custodian  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.

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 

                                        - 7 -
<PAGE>
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  held in a segregated account by its custodian) upon conversion or
exchange  of other  securities  held in its  portfolio.  A call  option  is also
covered if 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 maintained by
the Fund in cash,  short-term  money  market  instruments  or high  quality debt
securities in a segregated account with its custodian. A put option written by a
Fund  is  "covered"  if  the  Fund  maintains  cash,   short-term  money  market
instruments or  high-quality  debt securities with a value equal to the exercise
price in a  segregated  account with its  custodian,  or else holds a put on the
same  security  and in the same  principal  amount as the put written  where the
exercise price of the put held is equal to or greater than the exercise price of
the put  written  or where the  exercise  price of the put held is less than the
exercise price of the put written if the difference is maintained by the Fund in
cash,  short-term money market  instruments or high-quality debt securities in a
segregated  account with its custodian.  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 counter  party 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 cash, short-term money market
instruments or high-quality debt securities.  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-

                                        - 7 -
<PAGE>
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.
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  held  in  a  segregated  account  by  its  custodian)  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 maintained by
the Fund in cash,  short-term  money market  instruments  or  high-quality  debt
securities in a 

                                        - 8 -
<PAGE>
segregated account with its custodian.  Each Fund may cover put options on stock
indices by maintaining cash, short-term money market instruments or high-quality
debt securities with a value equal to the exercise price in a segregated account
with its custodian,  or 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 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 maintained by the Fund in cash,  short-term  money
market  instruments or high-quality debt securities in a segregated account with
its custodian. 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 maintains in a
segregated  account with its custodian  cash or cash  equivalents  sufficient to
cover the  Fund's  net  liability  under the two  options.  Therefore,  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 are
illiquid and, therefore, cannot exceed the SEC illiquidity ceiling.

                                        - 9 -
<PAGE>
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  ("Futures
Contracts")  on stock  indices,  and may purchase and sell Futures  Contracts on
foreign currencies or indices of foreign currencies. The Equity Income 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.  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 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

                                        - 10 -
<PAGE>
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 maturity, 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  consistent with statements by the SEC and
its staff  regarding  the use of  Forward  Contracts  by  registered  investment
companies,  which require the use of segregated  assets or "cover" in connection
with the purchase and sale of such  Contracts.  In those  instances in which the
Fund satisfies this requirement through segregation of assets, it will maintain,
in a segregated  account,  cash, cash equivalents or high grade debt securities,
which will be marked to market on a daily basis, in an amount equal to the value
of its commitments under Forward Contracts.

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 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

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 maintained by the Fund in cash or securities in a segregated
account  with its  custodian.  A Fund may cover the  writing  of put  Options on
Futures  Contracts (a) through sales of the  underlying  Futures  Contract,  (b)
through segregation of cash, short-term money market instruments or high-quality
debt  securities  in an  amount  equal  to the  value of the  security  or index
underlying the Futures Contract, or (c) through the holding of a put on the same
Futures  Contract and in the same principal  amount as the put written where the
exercise price of the put held is equal to or greater than the exercise price of
the put  written  or where the  exercise  price of the put held is less than the
exercise price of the put written if the difference is maintained by the Fund in
cash,  short-term money market  instruments or high quality debt securities in a
segregated account with its custodian. 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,  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,

                                        - 12 -
<PAGE>
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 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.

                                        - 13 -
<PAGE>
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 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

                                        - 14 -
<PAGE>
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.

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.

                                        - 15 -
<PAGE>
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 and Options on Futures Contracts only (i)
for bona fide  hedging  purposes (as defined in CFTC  regulations),  or (ii) for
non-hedging purposes, provided that the aggregate initial margin and premiums on
such  non-hedging  positions does not exceed 5% of the liquidation  value of the
Fund's  assets.  In  addition,  the Fund must  comply with the  requirements  of
various state securities laws in connection with such transactions.

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

When a Fund purchases a Futures  Contract,  an amount of cash or securities will
be  deposited  in a  segregated  account  with the Fund's  custodian so that the
amount so segregated will at all times equal the value of the Futures  Contract,
thereby  ensuring  that  the  leveraging  effect  of such  Futures  Contract  is
minimized.

RISKS OF INVESTING IN LOWER RATED BONDS

The  Equity  Income  Fund,  the  Special  Opportunities  Fund,  the  Convertible
Securities Fund, the New Discovery Fund, and the Science and Technology 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") or Fitch Investors Service, Inc. ("Fitch"),  and
comparable  unrated  securities.  These  securities,  while normally  exhibiting
adequate protection parameters,  have speculative characteristics and changes in
economic conditions or other circumstances are more likely to lead to a weakened
capacity to make  principal  and  interest  payments  than in the case of higher
grade fixed income securities.

These  Funds may also  invest in fixed  income  securities  rated Ba or lower by
Moody's  or BB or lower  by S&P or  Fitch,  and  comparable  unrated  securities
(commonly known as "junk bonds") 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.

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

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

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):

Each Fund may not:

     (1)  borrow  amounts  in excess of 331/3 of its  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 in selling a portfolio security;

     (3)  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;

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

     (5)  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; or

     (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).

Except with respect to Investment Restriction (1), these investment restrictions
are adhered to at the time of purchase or  utilization  of assets;  a subsequent
change in  circumstances  will not be  considered  to result in a  violation  of
policy.

In addition,  each Fund has the following  nonfundamental  policies which may be
changed without shareholder approval. Each Fund will not:

     (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 5% 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 2% 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;

     (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

                                        - 17 -
<PAGE>
          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;
          or

     (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.

3.       MANAGEMENT OF THE FUNDS

<PAGE>
*  "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.  Mr. Brodkin,  the Chairman of MFD,  Messrs.  Shames and
Scott,  Directors  of MFD, and Mr.  Cavan,  the  Secretary of MFD,  hold similar
positions  with certain  other MFS  affiliates.  Mr. Bailey is a Director of Sun
Life  Assurance  Company of Canada  (U.S.)  ("Sun Life of Canada  (U.S.)"),  the
corporate parent of MFS.

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. Brodkin, 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.

Set  forth in  Appendix  A hereto is  certain  information  concerning  the cash
compensation paid by each Fund during its last fiscal year to the Trustees.

As of August 31,  1996,  the Trustees and officers as a group owned less than 1%
of each Fund's shares, not including the 671,188 shares of the Aggressive Growth
Fund,  28,720 shares of the Core Growth Fund,  9,892 shares of the Equity Income
Fund and 136,098  shares of the  Special  Opportunities  Fund  (which  represent
approximately  81.1%,  51.6% 22.9% and 68.5% of the  outstanding  shares of each
such Fund,  respectively)  owned of record by certain  employee benefit plans of
MFS of which Messrs. Brodkin, Scott and Shames are Trustees.

As  of  August  31,  1996,  MFS  Defined  Contribution  Plan,  c/o  Mark  Leary,
Massachusetts  Financial  Services  Company,  500 Boylston  Street,  Boston,  MA
02116-3740 was the record owner of approximately 81.09% of the outstanding Class
A shares of the Aggressive Growth Fund.

As  of  August  31,  1996,  MFS  Defined  Contribution  Plan,  c/o  Mark  Leary,
Massachusetts  Financial  Services  Company,  500 Boylston  Street,  Boston,  MA
02116-3740,  Ruth M. Scott, 176 Fisherville  Lane,  Westport,  MA 02790-1506 and
Massachusetts Financial Services Company, c/o Robert Blake, 500 Boylston Street,
Boston, MA 02116-3740 were the record owners of approximately  51.60%, 5.39% and
36.44%, respectively, of the outstanding Class A shares of the Core Growth Fund.

As  of  August  31,  1996,  MFS  Defined  Contribution  Plan,  c/o  Mark  Leary,
Massachusetts  Financial  Services  Company,  500 Boylston  Street,  Boston,  MA
02116-3740 was the record owner of approximately  92.5% of the outstanding Class
A shares of the Equity Income Fund.

As  of  August  31,  1996,  MFS  Defined  Contribution  Plan,  c/o  Mark  Leary,
Massachusetts  Financial  Services  Company,  500 Boylston  Street,  Boston,  MA
02116-3740, and Robert J. Manning and Donna Manning, JTWROS, 13 Rockyledge Road,
Swampscott,  MA 01907-2821,  were the record owners of approximately  68.45% and
17.95%,  respectively,  of  the  outstanding  Class  A  shares  of  the  Special
Opportunities Fund.

The Convertible Securities Fund, the Blue Chip Fund, the New Discovery Fund, the
Science and Technology Fund and the Research International Fund did not commence
investment operations prior to August 31, 1996.

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.),  which is a 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 Equity Income Fund, the Core Growth Fund, the Aggressive Growth Fund and the
Special  Opportunities  Fund,  and  December  ___,  1996,  with  respect  to the
remaining funds (the "Advisory Agreements"). The Adviser provides each Fund with
overall  investment  advisory and  administrative  services,  as well as general
office facilities.  Subject to such policies as the Trustees may determine,  the
Adviser  makes  investment  decisions  for each  Fund.  For these  services  and
facilities,  the Adviser  receives an annual  management fee,

                                        - 19 -
<PAGE>
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 on January 2,
1996 to the fiscal year end of August 31, 1996,  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 except the Aggressive  Growth
Fund.

In order to comply  with the expense  limitations  of certain  state  securities
commissions,  the Adviser will reduce its management fee or otherwise  reimburse
each  Fund  for  any  expenses,  exclusive  of  interest,  taxes  and  brokerage
commissions,  incurred  by each  Fund in any  fiscal  year  to the  extent  such
expenses  exceed the most  restrictive  of such state expense  limitations.  The
Adviser will make appropriate  adjustments to such reimbursements in response to
any amendment or rescission of the various state requirements.

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

Each Advisory Agreement will remain in effect until August 1, 1997, with respect
to the Equity Income Fund, the Core Growth Fund, the Aggressive  Growth Fund and
the Special  Opportunities  Fund,  and until  August 1, 1998 with respect to the
remaining Funds, 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.

SUB-INVESTMENT ADVISERS

FCM - FCM serves as the Research  International Fund's sub-adviser pursuant to a
Sub-Advisory  Agreement dated  _________,  1996 between the Adviser and FCM (the
"FCM Sub-Advisory Agreement").  The FCM Sub-Advisory Agreement provides that the
Adviser may delegate to FCM the authority to make  investment  decisions for the
Fund. For these  services,  the Adviser pays FCM an annual fee computed and paid
monthly  in an amount  equal to 0.40% of the  average  daily net  assets of such
Fund.

FCEM - FCEM serves as the Research  International Fund's sub-adviser pursuant to
a separate Sub-Advisory Agreement dated ________, 1996 between FCM and FCEM (the
"FCEM  Sub-Advisory  Agreement,"  the "FCM  Agreement" and together with the FCM
Sub-Advisory Agreement,  the "FCM Agreements").  The FCEM Sub-Advisory Agreement
provides  that  FCM  may  delegate  to FCEM  the  authority  to make  investment
decisions  for the  Fund.  It is  presently  intended  that  FCEM  will  provide
portfolio management services for the portion of the assets of the Fund invested
in emerging markets securities.  For these services, FCM pays FCEM an annual fee
computed and paid  monthly in an amount  equal to [ ]% of the average  daily net
assets of the Fund managed by FCEM.

SUB-ADVISORY  AGREEMENTS  - Each  Sub-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 the vote of a majority of the relevant Fund's outstanding  shares, and, in
either  case,  by a  majority  of  the  Trustees  who  are  not  parties  to the
Sub-Advisory   Agreement  or  interested   persons  of  any  such  party.   Each
Sub-Advisory  Agreement  terminates  automatically  if it is assigned and may be
terminated without penalty by the Trustees,  by vote of a majority of the Fund's
outstanding  shares,  by the  Adviser on not less than 30 days' nor more than 60
days' written  notice or, by the  Sub-Adviser on not less than 60 days' nor more
than 90 days' written notice.

Each Sub-Advisory Agreement  specifically provides that no Sub-Adviser,  nor its
personnel shall be liable for any error or 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  Sub-Advisory
Agreement.

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

                                        - 20 -
<PAGE>
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. The Custodian has contracted with the Adviser for
the  Adviser  to  perform  certain  accounting   functions  related  to  options
transactions for which the Adviser receives remuneration on a cost basis.

SHAREHOLDER SERVICING AGENT

MFS Service Center,  Inc. (the "Shareholder  Servicing  Agent"),  a wholly owned
subsidiary of MFS, is each Fund's  shareholder  servicing agent,  pursuant to an
Amended and Restated Shareholder  Servicing Agreement dated January 2, 1996 (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  class of shares at an
effective  annual rate of up to 0.15%, up to 0.22% and up to 0.15%  attributable
to  Class  A,  Class B and  Class  C  shares,  respectively.  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 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% 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  AND CLASS C  SHARES:  MFD acts as agent in  selling  Class B and
Class C shares of each Fund to dealers. The public offering price of Class B and
Class C shares  is their  net  asset  value  next  computed  after the sale (see
"Purchases" in the Prospectus).

GENERAL:  Neither MFD nor  dealers  are  permitted  to delay  placing  orders to
benefit themselves by a price change. On occasion,  MFD may obtain brokers loans
from  various  banks,  including  the  custodian  banks  for the MFS  Funds,  to
facilitate  the  settlement  of sales of  shares of 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, 1997 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 Rules of Fair Practice
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 $23,100 of  commission  business  from the MFS Funds to the
Pershing Division of Donaldson Lufkin & Jenrette as consideration for the annual
renewal  of the  Lipper  Directors'  Analytical  Data  Service  (which  provides
information useful to the Trustees in reviewing the relationship  between a Fund
and the Adviser).

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 period ended August 31, 1996,  the Equity Income Fund ("EIF"),  the Core
Growth  Fund  ("CGF"),  the  Aggressive  Growth  Fund  ("AGF")  and the  Special
Opportunities Fund ("SOF") paid

                                        - 22 -
<PAGE>
total brokerage commissions on total transactions as follows:

                  TOTAL                     TOTAL
               COMMISSIONS              TRANSACTIONS

   EIF            $ 783                   $ 713,627
   CGF           $ 1,544                 $ 1,398,932
   AGF           $19,205                 $13,710,580
   SOF           $ 3,451                 $ 2,016,503

Not all of the Fund's transactions are equity security transactions.  During the
period ended August 31, 1996,  the  Aggressive  Growth Fund acquired  securities
issued by Charles Schwab Inc. and Merrill Lynch,  Pierce,  Fenner & Smith, Inc.,
regular  broker-dealers  of the Fund, which securities had a value of $6,125 and
$6,250, respectively, as of August 31, 1996.

The Convertible Securities Fund, the Blue Chip Fund, the New Discovery Fund, the
Science and Technology Fund and the Research International Fund did not commence
investment operations prior to August 31, 1996.

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.

         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 all classes of shares
of that shareholder in the MFS Funds or MFS Fixed Fund reaches a discount level.
See  "Purchases" in the Prospectus for the sales charges on quantity  discounts.
For example, if a shareholder owns shares with a 

                                        - 23 -
<PAGE>
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.

         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  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
four  different  funds  effective  on the  seventh day of each month or of every
third month, depending whether monthly or quarterly exchanges are elected by the
shareholder.  If the  seventh  day of the  month  is  not a  business  day,  the
transaction will be processed on the next business day.  Generally,  the initial
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

                                        - 24 -
<PAGE>
funds may not be available for exchanges until the following  month;  therefore,
care should be used to avoid  inadvertently  terminating the Automatic  Exchange
Plan through exhaustion of the account balance.

No  transaction  fee for  exchanges  will be  charged  in  connection  with  the
Automatic Exchange Plan. However,  exchanges of shares of MFS Money Market Fund,
MFS  Government  Money  Market Fund and Class A shares of MFS Cash  Reserve Fund
will be  subject  to any  applicable  sales  charge.  Changes  in  amounts to be
exchanged  to each  fund,  the Funds to which  exchanges  are to be made and the
timing of exchanges  (monthly or quarterly),  or termination of a  shareholder's
participation in the Automatic  Exchange Plan will be made after instructions in
writing or by  telephone  (an  "Exchange  Change  Request")  are received by the
Shareholder Servicing Agent in proper form (I.E., if in writing -- signed by the
record  owner(s)  exactly as shares 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)
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 

                                        - 25 -
<PAGE>
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:

     Individual   Retirement   Accounts   (IRAs)  (for   individuals  and  their
     Non-employed  spouses  who  desire  to  make  limited  contributions  to  a
     Tax-deferred  retirement  program  and, if  eligible,  to receive a federal
     Income tax deduction for amounts contributed);
     Simplified Employee Pension (SEP-IRA) Plans;
     Retirement  Plans  Qualified  under Section 401(k) of the Internal  Revenue
     Code of 1986, as amended (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  intends  to  elect  to be  treated  and to  qualify  each  year as a
"regulated  investment  company" under Subchapter M of the Internal Revenue Code
of 1986,  as amended (the "Code"),  by meeting all  applicable  requirements  of
Subchapter  M,  including  requirements  as to the  nature of the  Fund's  gross
income, the amount of Fund distributions, and the composition and holding period
of the Fund's portfolio  assets.  Because 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 will have to pay federal income taxes and any state or
local taxes on the  dividends and capital gain  distributions  they receive from
the Fund.  Dividends from ordinary income and distributions  from net short-term
capital gains  (whether  paid in cash or  reinvested  in additional  shares) are
taxable to shareholders  as ordinary  income for federal income tax purposes.  A
portion of these dividends (but none of the  distributions  of capital gains) is
normally eligible for the  dividends-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  shareholders  is
subject to  certain  limitations,  and  deducted  amounts  may be subject to the
alternative   minimum  tax  and  may  result  in  certain   basis   adjustments.
Distributions  from net capital gains (I.E., the excess of net long-term capital
gains over net short-term capital losses), whether paid in cash or 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 owned  their  shares.  Fund  dividends  that are  declared in
October,  November or December,  that are payable to  shareholders  of record in
such a  month,  and  that are paid the  following  January  will be  taxable  to
shareholders  as if  received  on  December  31 of the  year in  which  they are
declared.

Any dividend or distribution  will have the effect of reducing the per share net
asset value of shares in a Fund by the amount of the  dividend or  distribution.
Shareholders  purchasing  shares  shortly  before the record date of any taxable
dividend  or other  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  long-term  capital  gain or loss if the

                                        - 26 -
<PAGE>
shares have been held for more than twelve  months and  otherwise as  short-term
capital gain or loss. 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  redemption  of  shares  may also be
disallowed  under rules  relating to wash sales.  Gain may be increased (or loss
reduced)  upon a redemption of Class A shares of a Fund within ninety days after
their purchase followed by any purchase  (including  purchases by exchange or by
reinvestment) without payment of an additional sales charge of Class A shares of
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 may affect the amount,
timing,  and character of  distributions  to shareholders  and may under certain
circumstances  make an economic  return of capital  taxable to  shareholders.  A
Fund's  investments  in zero coupon bonds,  deferred  interest  bonds,  stripped
securities,  PIK bonds,  and certain  securities  purchased at a market discount
will cause it to realize  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  has  state  or  local  governments  or other
tax-exempt organizations as shareholders.

Each Fund's  transactions in options,  Futures  Contracts and Forward  Contracts
will be  subject to special  tax rules  that may affect the  amount,  timing and
character of 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 such day, and any gain or
loss  associated  with the  positions  will be treated as 60%  long-term and 40%
short  term  capital  gain  or  loss.  Certain  positions  held  by a Fund  that
substantially  diminish its risk of loss with respect to other  positions in its
portfolio will 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,  short sales 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.
For example,  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.

Investment  income received by a Fund from foreign  securities may be subject to
foreign income taxes.  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 Fund's
assets to be invested within various countries is not known.  Except in the case
of the Research  International  Fund, 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. If the Research  International Fund holds more than 50%
of its assets in foreign stock and  securities at the close of its taxable year,
it may elect to "pass through" to its shareholders foreign income taxes paid. If
the Research  International Fund so elects, its shareholders will be required to
treat their pro rata  portion of the foreign  income  taxes paid by that Fund as
part of the amounts distributed to them by the Fund and thus includable in their
gross  income  for  federal  income  tax  purposes.   Shareholders  who  itemize
deductions  would then be allowed to claim a deduction  or credit (but not both)
on their  federal  income  tax  returns  for such  amounts,  subject  to certain
limitations.  Shareholders who do not itemize  deductions would (subject to such
limitations)  be able to claim a credit but not a deduction.  No  deduction  for
such amounts will be permitted to  individuals  in computing  their  alternative
minimum tax liability.  If the Research  International  Fund does not qualify or
elect to "pass through" to its shareholders foreign income taxes paid by it, its
shareholders  will not be able to claim any  deduction or credit for any part of
the foreign taxes paid by that Fund.

Dividends  and  certain  other  payments  to  persons  who are not  citizens  or
residents  of the  United  States  or U.S.  entities  ("Non-U.S.  Persons")  are
generally  subject to U.S. tax withholding at the rate of 30%. Each Fund intends
to withhold  U.S.  federal  income tax at the rate of 30% on dividends and other
payments  made to  Non-U.S.  Persons  that  are  subject  to  such  withholding,
regardless  of  whether  a lower  treaty  rate  may be  permitted.  Any  amounts
overwithheld  may be recovered by such persons by filing a claim for refund with
the U.S.  Internal  Revenue  Service  within the time period  applicable to such
claims.  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 a rate of 31%
on taxable  dividends and the proceeds of redemptions  and exchanges 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.

Fund  distributions  that are derived from interest on  obligations  of the U.S.
Government and certain of its agencies and instrumentalities  (but generally not
from capital gains  realized upon the  disposition of such  obligations)  may be
exempt from

                                        - 27 -
<PAGE>
state and local taxes.  Each Fund intends to advise  shareholders of the extent,
if any, to which its  distributions  consist of such interest.  Shareholders are
urged to consult  their tax advisors  regarding  the possible  exclusion of such
portion of their  dividends  for state and local  income tax purposes as well as
regarding the tax consequences of an investment in a Fund.

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 PLANS

The Trustees have adopted separate  Distribution  Plans for Class A, Class B and
Class C shares (the "Distribution  Plans") pursuant to Section 12(b) of the 1940
Act and Rule 12b-1  thereunder (the "Rule") after having concluded that there is
a reasonable  likelihood that each Distribution Plan would benefit each Fund and
the respective  class of shareholders.  The  Distribution  Plans are 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  Plans are  described  in the  Prospectus  under  the  caption
"Distribution  Plans," which is incorporated herein by reference.  The following
information supplements this Prospectus discussion.

SERVICE  FEES:  With respect to the Class A  Distribution  Plan, 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 the Class B Distribution  Plan,  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
any  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 Plans 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,  January 2, 1996, to the
fiscal year ended August 31, 1996, distribution and service fees under the Class
A, Class B and Class C Distribution Plans were not imposed.

GENERAL:  Each of the  Distribution  Plans will remain in effect until August 1,
1997,  and will  continue  in  effect  thereafter  only if such  continuance  is
specifically  approved  at least  annually  by vote of both the  Trustees  and a
majority  of the  Trustees  who  are not  "interested  persons"  or  financially
interested parties of such Plan ("Distribution Plan Qualified  Trustees").  Each
of the Distribution Plans 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. Each of
the  Distribution  Plans may be  terminated at any time by vote of a majority of
the Distribution Plan Qualified Trustees or by vote of the holders of a majority
of the  respective  class  of the  Fund's  shares  (as  defined  in  "Investment
Restrictions"). All agreements relating to any of the Distribution Plans entered
into  between  the Fund or MFD and other  organizations  must be approved by the
Board of  Trustees,  including a majority  of the  Distribution  Plan  Qualified
Trustees.  Agreements  under any of the  Distribution  Plans must be in writing,
will be terminated  automatically if assigned, and may be terminated at any time
without payment of any penalty,  by vote of a majority of the Distribution  Plan
Qualified  Trustees or by vote of the  holders of a majority  of the  respective
class of a Fund's  shares.  None of the  Distribution  Plans may be  amended  to
increase  materially the amount of permitted  distribution  expenses without the
approval of a majority of the respective  class of the Fund's shares (as defined
in "Investment Restrictions") or may be materially amended in any case without a
vote of the Trustees and a majority of the Distribution Plan Qualified Trustees.
The selection and nomination of  Distribution  Plan Qualified  Trustees shall be
committed to the discretion of the  non-interested  Trustees then in office.  No
Trustee who is not an "interested  person" has any financial  interest in any of
the Distribution Plans or in any related agreement.

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,  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 system
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  system.  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
system,  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 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  purchased after April 1, 1996) 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%  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.

The aggregate  total rates of return for Class A shares for the following  Funds
for the period from January 2, 1996 (the commencement of investment  operations)
to August 31, 1996 are as follows:

                               INCLUDING      WITHOUT
                               EFFECT OF     EFFECT OF
                                 SALES         SALES
                                CHARGE         CHARGE
Aggressive Growth Fund          16.76%         22.60%
Core Growth Fund                17.43%         22.30%
Equity Income Fund               5.43%         10.70%
Special Opportunities Fund       8.19%         13.60%

Class B and C shares were not available for sale during this period.

The Convertible Securities Fund, the Blue Chip Fund, the New Discovery Fund, the
Science and Technology Fund and the Research International Fund did not commence
investment operations prior to August 31, 1996.

Total rates 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% in the case of Class A shares  and no payment of
any CDSC in the case of Class B and Class C shares.

The yields for Class A shares of each Fund for the 30-day  period  ended  August
31, 1996 were as follows:

                                 ACTUAL          30-DAY

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%. The Fund's current  distribution
rate calculation for Class B and Class C shares assumes no CDSC is paid.

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,
Morningstar, Lipper Analytical Services, Inc., CDA Wiesenberger, Shearson Lehman
and Salomon Bros.  Indices,  Ibbotson,  Business Week, Lowry  Associates,  Media
General,  Investment  Company Data,  The New York Times,  Your Money,  Strangers
Investment  Advisor,  Financial  Planning on Wall  Street,  Standard and Poor's,
Individual  Investor,  THE 100 BEST  MUTUAL  FUNDS  YOU CAN BUY,  by  Gordon  K.
Williamson,   Consumer  Price  Index,  and  Sanford  C.  Bernstein  &  Co.  Fund
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.

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 four 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 P
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

                                        - 31 -
<PAGE>
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,
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.
