(1)      Purchases  of $1  million or more 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.  Absent this waiver,  "Management  Fees" would be 0.75%
         per annum for each 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 not  currently  being
         imposed.  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  with  any CDSC  payable  upon  redemption  of Class B
         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.
<PAGE>
(5)      "Other  Expenses"  are based on estimates of payments to be made during
         each Fund's current fiscal year. As discussed  below in footnote 6, the
         Adviser  is  bearing  certain   expenses  of  each  Fund,   subject  to
         reimbursement by the Funds. Absent this arrangement,  "Other Expenses,"
         expressed as a percentage of average daily net assets,  would be 3.36%,
         3.43% and 3.36% for Class A shares,  Class B shares and Class C shares,
         respectively, for each Fund.

(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," such that "Total  Operating  Expenses"
         do not exceed, on an annualized basis,  1.50% of a Fund's average daily
         net assets with  respect to Class A shares,  2.57% of a Fund's  average
         daily net assets with respect to Class B shares,  and 2.50% of a 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.  This
         arrangement  may be 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 4.11%,
         5.18% and 5.11% for Class A shares,  Class B shares and Class C shares,
         respectively, for each Fund.

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 eight  series,  three 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,  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 (or a CDSC in the case of certain  purchases
of $1  million or more) and  subject to a  Distribution  Plan  providing  for an
annual distribution fee and service fee. Class B shares are offered at net asset
value  without an initial  sales  charge but subject to a CDSC and  Distribution
Plan providing for an annual  distribution fee and service fee which are greater
than the Class A  distribution  fee and service fee; Class B shares will convert
to Class A shares  approximately eight years after purchase.  Class C shares are
offered at net asset value without an initial sales charge or a CDSC but subject
to a Distribution Plan providing for an annual  distribution fee and service fee
which are equal to the Class B annual  distribution fee and service fee; Class C
shares do not convert to any other class of shares of a Fund.
<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.       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 may, unless otherwise specifically stated, 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.
<PAGE>

EQUITY INCOME FUND - The Equity Income Fund's investment objective is to achieve
a yield that  exceeds the yield of the S&P 500. In  selecting  investments,  the
Fund also considers the potential for 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 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  Rating  Group
("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 A to this Prospectus. See "Additional
Risk Factors - Lower Rated Bonds" below.

Consistent with its investment  objective 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 a U.S. exchange.

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

RESEARCH  GROWTH  AND  INCOME  FUND - The  Research  Growth  and  Income  Fund's
investment  objective is long-term growth of capital,  current income and growth
of income.

Under  normal  market  conditions,  the Fund  invests  at least 65% of its total
assets in equity securities of companies which, in the Adviser's judgment, offer
earnings  growth  potential  while paying  current  dividends  (see  "Investment
Techniques - Equity Securities" below). Over time,  continued growth of earnings
tends to lead to higher dividends and enhancement of capital value. The Fund may
also invest up to 35% of its total assets in equity  securities which do not pay
current  dividends  but which offer  prospects  for growth of capital and future
income.

Consistent with its investment  objective and policies described above, the Fund
may also 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 a U.S.
exchange.

The  portfolio  securities of the Fund are selected by the  investment  research
analysts in the Equity  Research  Group of the  Adviser.  The Fund's  assets are
allocated  to  industry  groups  (E.G.,  pharmaceuticals,  retail  and  computer
software). The allocation by industry group is determined by the analysts acting
together.  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 industry groups.

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

CORE GROWTH FUND - The Core Growth  Fund's  investment  objective  is  long-term
growth of capital.

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.
<PAGE>

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 a U.S. exchange.

The Fund may engage in certain  investment  techniques  as  described  under the
caption  "Investment  Techniques"  below  and in  the  Statement  of  Additional
Information under the caption  "Investment  Techniques." The Fund's  investments
are subject to certain risks, as described in the  above-referenced  sections of
this  Prospectus  and the Statement of Additional  Information  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 have  above-average
growth potential (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 a U.S. exchange.

The Fund may engage in certain  investment  techniques  as  described  under the
caption  "Investment  Techniques"  below  and in  the  Statement  of  Additional
Information under the caption  "Investment  Techniques." The Fund's  investments
are subject to certain risks, as described in the  above-referenced  sections of
this  Prospectus  and the Statement of Additional  Information  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, in the Adviser's opinion, lead 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).
<PAGE>
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 A
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).
<PAGE>

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 35% (and generally expects to invest between 5% and 20%) of its
net assets in foreign equity and fixed-income securities which are not traded on
a U.S. exchange.

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

4.       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 Statement of Additional Information.

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

         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 additional 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

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

         INVESTMENTS FOR TEMPORARY DEFENSIVE PURPOSES: During periods of unusual
market  conditions  when the  Adviser  believes  that  investing  for  temporary
defensive  purposes is appropriate,  or in order to meet anticipated  redemption
requests, a large portion or all of the assets of a Fund may be invested in cash
(including foreign currency) or cash equivalents including,  but not limited to,
obligations of banks (including  certificates of deposit,  bankers' acceptances,
time deposits and repurchase  agreements),  commercial paper,  short-term notes,
U.S.
Government Securities and related repurchase agreements.

         EMERGING  MARKETS  SECURITIES:  Consistent with each Fund's  respective
objective and policies, each Fund may invest in securities of issuers (which may
include   foreign    governments   and   their    subdivisions,    agencies   or
instrumentalities)  located in emerging  markets.  Emerging  markets include any
country:  (i) having an "emerging stock market" as defined by the  International
Finance Corporation;  (ii) with low- to middle-income economies according to the
International  Bank for  Reconstruction  and Development (the World Bank); (iii)
listed in World Bank  publications  as  developing;  or (iv)  determined  by the
Adviser  to be an  emerging  market as defined  above.  The  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.

         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 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 value
may increase or decrease if the underlying instrument appreciates), and may have
return   characteristics   similar  to  direct  investments  in  the  underlying
instrument  or to one or more  options  on the  underlying  instrument.  Indexed
securities may be more volatile than the underlying instrument itself.
<PAGE>
         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 indexes,  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.

         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.
<PAGE>

         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 Statement
of Additional Information.

         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.
<PAGE>

         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 Statement of Additional Information. The trading of yield curve
options is subject  to all the risks  associated  with  trading  other  types of
options, as discussed below under "Additional Risk Factors" and in the Statement
of Additional Information.  In addition, such options present risks of loss even
if the yield on one of the underlying securities remains constant, if the spread
moves in a direction or to an extent which was not anticipated.
<PAGE>

         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 and the Special Opportunities 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. The Equity Income Fund and the Special Opportunities Fund
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.
<PAGE>

         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 to, or be
required to, receive delivery of the foreign  currencies  underlying  Options on
Foreign  Currencies it has entered into.  Under certain  circumstances,  such as
where the Adviser  believes that the applicable  exchange rate is unfavorable at
the time the currencies are received or the Adviser  anticipates,  for any other
reason, that the exchange rate will improve, a Fund may hold such currencies for
an indefinite period of time.
<PAGE>

INVESTMENT TECHNIQUES APPLICABLE TO EQUITY INCOME FUND AND SPECIAL OPPORTUNITIES
FUND. The following  investment  techniques  are  applicable  only to the Equity
Income Fund and/or the Special Opportunities Fund, as specified:

         MORTGAGE  "DOLLAR  ROLL"  TRANSACTIONS:  The Equity Income Fund and the
Special  Opportunities  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 and the
Special  Opportunities  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.
<PAGE>

         ZERO COUPON BONDS,  DEFERRED  INTEREST BONDS AND PIK BONDS:  The Equity
Income Fund and the Special  Opportunities 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.
<PAGE>

         COLLATERALIZED   MORTGAGE   OBLIGATIONS  AND  MULTICLASS   PASS-THROUGH
SECURITIES:  The Equity Income Fund and the Special  Opportunities 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 and the  Special  Opportunities  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 and the
Special  Opportunities  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 and the
Special  Opportunities 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.
<PAGE>

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

         SHORT SALES: If the Special  Opportunities  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.
The 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.  The  Special
Opportunities Fund's short sales must be fully collateralized, and the Fund will
not sell  short  securities  whose  underlying  value  exceeds  25% of its total
assets. The Fund limits short sales of any one issuer's  securities to 2% of the
Fund's total assets and to 2% of any one class of the issuer's securities.

         BORROWING AND LEVERAGE:  The Special Opportunities Fund may borrow from
banks up to one third of its total  assets,  and may pledge assets in connection
with such  borrowings.  Additional  investments by the Fund while borrowings are
outstanding may be construed as a form of leverage. This leverage may exaggerate
changes  in the  Fund's  share  value  and the gains  and  losses on the  Fund's
investment.  Leverage also creates interest  expenses that may exceed the return
on investments made with the borrowings.

5.       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  Statement  of  Additional
Information.

         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.
<PAGE>

         EMERGING GROWTH COMPANIES: The Core Growth Fund, Aggressive Growth Fund
and Special  Opportunities  Fund may invest in  securities  of  emerging  growth
companies,   including  established  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 these Funds will involve a higher
degree of risk than would established growth stocks.

         FIXED   INCOME   SECURITIES:   The  Equity   Income  Fund  and  Special
Opportunities  Fund may  generally  invest in 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.  Each such Fund is subject to no  restrictions  on the
maturities of the fixed income  securities  it holds.  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.
<PAGE>

         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  Statement  of  Additional  Information  contains a
description of the nature and trading mechanics of options,  Futures  Contracts,
Options  on  Futures  Contracts,   Forward  Contracts  and  Options  on  Foreign
Currencies,  and  includes a  discussion  of the risks  related to  transactions
therein.

         Transactions  in  Forward  Contracts  may be  entered  into only in the
over-the-counter  market. Futures Contracts and Options on Futures Contracts may
be entered into on U.S.  exchanges  regulated by the Commodity  Futures  Trading
Commission  and on foreign  exchanges.  In addition,  the securities 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 and the Special Opportunities
Fund may  invest  in  fixed  income  securities,  and each  Fund 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.

         The Equity  Income  Fund and the  Special  Opportunities  Fund may also
invest in securities rated Ba or lower by Moody's or BB or lower by S&P or Fitch
and comparable unrated securities (commonly known as "junk bonds") to the extent
described  above.  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.
<PAGE>

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

         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 United States securities exchanges,  the Adviser does not treat them as
foreign  securities.  However,  they are subject to many of the risks of foreign
securities  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 of repatriation
of assets,  and may have less  protection of property rights than more developed
countries. The economies of countries with emerging markets may be predominantly
based on only a few industries,  may be highly vulnerable to changes in local or
global trade  conditions,  and may suffer from extreme and volatile debt burdens
or  inflation  rates.  Local  securities  markets  may  trade a small  number of
securities  and may be unable to respond  effectively  to  increases  in trading
volume,  potentially making prompt liquidation of substantial holdings difficult
or impossible at times. Securities of issuers located in countries with emerging
markets  may have  limited  marketability  and may be subject to more  abrupt or
erratic 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.
<PAGE>

         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.

         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 Statement of Additional  Information.  Because
each Fund is expected to have a portfolio turnover rate of up to 300% 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.
<PAGE>

         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 Statement of Additional  Information 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 Statement of Additional  Information  may be changed
without  shareholder  approval unless indicated  otherwise (see the Statement of
Additional  Information).  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.

6.       MANAGEMENT OF THE FUNDS

INVESTMENT  ADVISER  -- The  Adviser  manages  each Fund  pursuant  to  separate
Investment  Advisory  Agreements,  each  dated  January  2, 1996 (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 the  following  annual  rates of the  average  daily net assets of each
Fund:

                                              PERCENTAGE OF THE AVERAGE DAILY
FUND                                              NET ASSETS OF EACH FUND

Equity Income Fund                                         0.75%
Research Growth and Income Fund                            0.75%
Core Growth Fund                                           0.75%
Aggressive Growth Fund                                     0.75%
Special Opportunities Fund                                 0.75%

The Adviser is currently waiving its right to receive  management fees from each
Fund.

The identity and  background  of the portfolio  manager(s)  for each Fund is set
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, 1995.  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
wholly owned subsidiary of Sun Life of Canada (U.S.),  which in turn is a wholly
owned  subsidiary  of Sun Life  Assurance  Company of Canada ("Sun  Life").  The
Directors of MFS are A. Keith Brodkin,  Jeffrey L. Shames, Arnold D. Scott, John
D. McNeil and John R. Gardner.  Mr.  Brodkin is the Chairman,  Mr. Shames is the
President and Mr. Scott is the Secretary and a Senior  Executive  Vice President
of MFS. Messrs. McNeil and Gardner are the Chairman and President, respectively,
of Sun Life.  Sun Life, a mutual life insurance  company,  is one of the largest
international life insurance  companies and has been operating in the U.S. since
1895, establishing a headquarters office here in 1973. The executive officers of
MFS report 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.
("Foreign & Colonial"). Foreign & Colonial 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  Weschsel-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 Foreign & Colonial will 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 will have access to the extensive  international equity
investment  expertise  of Foreign & Colonial,  and Foreign & Colonial  will have
access to the extensive U.S. equity investment expertise of MFS. One or more MFS
investment  analysts are expected to work for an extended  period with Foreign &
Colonial's  portfolio  managers  and  investment  analysts  at their  offices in
London. In return, one or more Foreign & Colonial employees are expected to work
in a similar manner at MFS' Boston offices.

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
Foreign & Colonial.  Some simultaneous  transactions are inevitable when several
clients receive investment advice from MFS and Foreign & Colonial,  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.

7.       INFORMATION CONCERNING SHARES OF THE FUNDS

PURCHASES

Shares of each Fund may be purchased at the public  offering  price  through any
dealer and other financial  institution  ("dealers")  having a selling agreement
with MFD.  Dealers may also charge their  customers fees relating to investments
in each Fund.

Each Fund offers three  classes of shares  (Class A, B and C shares)  which bear
sales charges and distribution fees in different forms and amounts, as described
below (currently, only Class A shares are available for sale):
<PAGE>

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

PURCHASES  SUBJECT TO INITIAL SALES  CHARGE.  Class A shares are offered at
net asset value plus an initial sales charge as follows:

<FN>

*    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.
</FN>
</TABLE>

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 Statement of Additional Information.

         PURCHASES  SUBJECT  TO A CDSC  (BUT NOT  SUBJECT  TO AN  INITIAL  SALES
CHARGE). In the following two circumstances,  Class A shares 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; and
<PAGE>

         (ii)     on investments in Class A shares by certain  retirement  plans
                  subject to the  Employee  Retirement  Income  Security  Act of
                  1974, as amended, if the sponsoring organization  demonstrates
                  to the satisfaction of MFD that either (a) the employer has at
                  least  25  employees  or (b) the  aggregate  purchases  by the
                  retirement  plan of Class A shares of the MFS Funds will be in
                  an amount of at least $250,000  within a reasonable  period of
                  time, as determined by MFD in its sole discretion.

         In the case of such purchases, MFD will pay a commission to dealers who
initiate and are responsible for purchases of $5 million or more as follows:  1%
on sales up to $5  million,  plus 0.25% on the  amount in excess of $5  million.
Purchases of $1 million or more for each shareholder  account will be aggregated
over a 12-month period (commencing from the date of the first such purchase) for
purposes of  determining  the level of  commissions to be paid during the period
with respect to such account.  In addition,  with respect to sales to retirement
plans under the second  circumstance  described above, MFD may pay a commission,
on sales in excess of $5 million to certain  retirement  plans, of 1% to certain
dealers which,  at MFD's  invitation,  enter into an agreement with MFD in which
the dealer agrees to return any  commission  paid to it on the sale (or on a pro
rata  portion  thereof) if the  shareholder  redeems his or her shares  within a
period of time after purchase as specified by MFD.

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 is waived.  These  circumstances  are
described in Annex A to this Prospectus.

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

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

*    While  Class B shares of the Funds  were not  offered  prior to  January 1,
     1993,  other MFS Funds offered Class B shares prior to this date. This CDSC
     schedule  will  apply to Class B shares  of a Fund  attributable  to shares
     exchanged  from any such  other MFS Fund which  were  originally  purchased
     prior to January 1, 1993.

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.

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).

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

     WAIVERS OF CDSC. In certain circumstances, the CDSC imposed upon redemption
of Class B shares is waived.  These  circumstances  are  described in Annex A to
this Prospectus.
<PAGE>

     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.
<PAGE>

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

Class C shares are not currently  available for purchase by any retirement  plan
qualified under Sections 401(a) or 403(b) of the Internal  Revenue Code of 1986,
as  amended  (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.

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

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

     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.
<PAGE>

     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 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.
<PAGE>

     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). In addition, Class C
shares may be  exchanged  for shares of the MFS Money  Market  Fund at net asset
value. Shares of one class may not be exchanged for shares of any other class.

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

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

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:  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 usually will occur
on that day if all the  requirements  set forth above have been complied with at
that time. No more than five  exchanges may be made in any one Exchange  Request
by telephone.  Additional  information  concerning  this exchange  privilege and
prospectuses  for any of the other MFS Funds may be obtained from dealers or the
Shareholder  Servicing  Agent.  A shareholder  should read the prospectus of the
other  MFS Fund  and  consider  the  differences  in  objectives,  policies  and
restrictions  before  making any  exchange.  For federal and  (generally)  state
income tax  purposes,  an exchange is treated as a sale of the shares  exchanged
and,  therefore,  an exchange could result in a gain or loss to the  shareholder
making the exchange.  Exchanges by telephone are automatically available to most
non-retirement  plan accounts and certain retirement plan accounts.  For further
information  regarding  exchanges by telephone,  see "Redemptions by Telephone."
The exchange  privilege (or any aspect of it) may be changed or discontinued and
is subject to certain  limitations,  including certain restrictions on purchases
by market timers.  Special procedures,  privileges and restrictions with respect
to exchanges may apply to market timers who enter into an agreement with MFD, as
set forth in such agreement. See "Purchases - General - Right to Reject Purchase
Orders/Market Timing."
<PAGE>

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 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.
<PAGE>

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 or Class B shares
("Direct Purchases") will be subject to a CDSC for a period of 12 months (in the
case of  purchases  of $1  million  or more of Class A shares  or  purchases  by
certain  retirement  plans  of  Class A  shares)  or six  years  (in the case of
purchases of Class B shares). Purchases of Class A shares made during a calendar
month, regardless of when during the month the investment occurred, will age one
month on the last day of the month  and each  subsequent  month.  Class B shares
purchased on or after  January 1, 1993 will be  aggregated  on a calendar  month
basis -- all  transactions  made  during a calendar  month,  regardless  of when
during the month they have occurred,  will age one year at the close of business
on the last day of such month in the following calendar year and each subsequent
year.  For Class B shares of each  Fund  purchased  prior to  January  1,  1993,
transactions  will be aggregated  on a calendar  year basis -- all  transactions
made  during a  calendar  year,  regardless  of when  during  the year they have
occurred, will age one year at the close of business on December 31 of that year
and each subsequent year.

At the time of a  redemption,  the amount by which the value of a  shareholder's
account for a particular class of shares represented by Direct Purchases exceeds
the  sum of the  six  calendar  year  aggregations  (12  months  in the  case of
purchases  of $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.
<PAGE>

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

     GENERAL:  The following  information applies to redemptions and repurchases
of all classes of a 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
certain Class A share purchases,  a CDSC will be imposed upon  redemption.  Such
purchases  under the  Reinstatement  Privilege are subject to all limitations in
the Statement of Additional Information regarding this privilege.

     IN-KIND DISTRIBUTIONS.  Subject to compliance with applicable  regulations,
each Fund has reserved the right to pay the  redemption or  repurchase  price of
shares of the Fund,  either totally or partially,  by a distribution  in-kind of
securities  (instead  of  cash)  from  the  Fund's  portfolio.   The  securities
distributed  in such a  distribution  would be valued at the same amount as that
assigned to them in  calculating  the net asset value for the shares being sold.
If a shareholder  received a distribution  in-kind,  the shareholder could incur
brokerage or transaction charges when converting the securities to cash.

     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 have not yet been imposed or
are being waived.  These  circumstances  are  described  below under the heading
"Current Level of Distribution and Service Fees."
<PAGE>

     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.
<PAGE>

     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  Statement of  Additional
Information.  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.

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 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.
<PAGE>

     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 a sales charge or a CDSC. See "Purchases - Class C shares" above. Unlike
the case  with  respect  to the sale of Class A and  Class B  shares,  where the
dealer  retains  a portion  of the  initial  sales  charge  (Class A shares)  or
receives an up-front payment from MFD (Class B shares), a dealer who sells Class
C shares does not receive any initial payment, but instead receives distribution
and service fees equal,  on an annual basis, to 1% of a Fund's average daily net
assets  attributable to Class C shares owned by investors for whom the dealer is
the holder or dealer of record.
<PAGE>

     This ongoing 1% 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.  Currently,  distribution and service
fees under the Class A Distribution Plan are not being imposed.

DISTRIBUTIONS

Each Fund intends to pay  substantially  all of its net investment income to its
shareholders as dividends at least  annually.  In determining the net investment
income  available for  distributions,  each Fund may rely on  projections of its
anticipated net investment income over a longer term, rather than its actual net
investment  income  for the  period.  If a Fund earns  less than  projected,  or
otherwise  distributes  more than its  earnings  for the year,  a portion of the
distributions may constitute a return of capital. Each Fund may make one or more
distributions  during the calendar year to its  shareholders  from any long-term
capital  gains and may also make one or more  distributions  during the calendar
year to its shareholders from short-term  capital gains.  Shareholders may elect
to receive dividends and capital gain distributions in either cash or additional
shares of the same class with respect to which a distribution  is made. See "Tax
Status" and "Shareholder Services -- Distribution Options" below.  Distributions
paid by a Fund with  respect to Class A shares will  generally  be greater  than
those  paid  with  respect  to  Class B and  Class  C  shares  because  expenses
attributable to Class B and Class C shares will generally be higher.

TAX STATUS

Each Fund is treated as an entity  separate  from the other  Funds and the other
series of the Trust for federal  income tax  purposes.  In order to minimize the
taxes each Fund would otherwise be required to pay, each Fund intends to qualify
each year as a "regulated  investment  company" under  Subchapter M of the Code,
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.
<PAGE>

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 a Fund's  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 receive 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 on payments  which have been subject to
30%   withholding.   Prospective   investors  should  read  the  Fund's  Account
Application for additional  information  regarding backup withholding of federal
income tax and should consult their own tax advisers as to the tax  consequences
to them of an investment in a Fund.
<PAGE>

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
Statement of Additional Information. 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  by the dealer
prior to its calculation and received by MFD 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 each Fund such that a Fund's
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 the 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, 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. 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.
<PAGE>

DESCRIPTION OF SHARES, VOTING RIGHTS AND LIABILITIES

Each Fund has three  classes  of shares,  entitled  Class A, Class B and Class C
shares  of  Beneficial  Interest  (without  par  value).  As of the date of this
Prospectus,  the Trust has eight  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 Statement of Additional Information).

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.
<PAGE>

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 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 shares  assumes  no CDSC is paid.  The  current
distribution  rate  differs  from the yield  calculation  because it may include
distributions  to  shareholders  from sources other than dividends and interest,
such as premium income from option writing, short-term capital gains, and return
of invested  capital,  and is calculated over a different  period of time. Total
rate of return quotations will reflect the average annual percentage change over
stated  periods in the value of an  investment in each class of shares of a Fund
made at the maximum  public  offering price of the shares of that class with all
distributions  reinvested and which, if quoted for periods of six years or less,
will give effect to the imposition of the CDSC assessed upon  redemptions of the
Fund's Class B shares.  Such total rate of return  quotations may be accompanied
by  quotations  which do not  reflect  the  reduction  in  value of the  initial
investment  due to the sales charge or the deduction of the CDSC, and which will
thus be higher. All performance  quotations are based on historical  performance
and are not intended to indicate  future  performance.  Yield  reflects only net
portfolio  income as of a stated  period of time and current  distribution  rate
reflects only the rate of  distributions  paid by 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  Statement  of  Additional
Information.  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.

8.    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").
<PAGE>

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,  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 Statement of  Additional  Information)  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.

         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,  as designated on the Account  Application and based upon the value of
his account.  Each payment under a Systematic  Withdrawal Plan (a "SWP") must be
at  least  $100,  except  in  certain  limited   circumstances.   The  aggregate
withdrawals  of Class B shares in any year pursuant to a SWP will not be subject
to a CDSC and are  generally  limited to 10% of the value of the  account at the
time of the establishment of the SWP. The CDSC will not be waived in the case of
SWP redemptions of Class A shares which are subject to 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.
<PAGE>

         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 Statement of Additional
Information  for further  information  concerning  the Automatic  Exchange Plan.
Investors  should  consult  their tax advisers  for  information  regarding  the
potential capital gain and loss consequences of transactions under the Automatic
Exchange Plan.

Because a dollar cost averaging  program involves  periodic  purchases of shares
regardless of fluctuating  share offering prices, a shareholder  should consider
his  financial  ability to continue his purchases  through  periods of low price
levels. Maintaining 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' Statement of Additional Information,  dated January 1, 1996, contains
more detailed information about each Fund, including 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.

                             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.
<PAGE>

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

     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.
<PAGE>

                                    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 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.

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.
<PAGE>

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,  irrevocable  letters of credit or
United States ("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 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.
<PAGE>

"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.
<PAGE>

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 depositary  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:  Each of the Equity  Income Fund and the
Special  Opportunities  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  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:  Each of the  Equity  Income  Fund  and the
Special  Opportunities  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.
<PAGE>

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: Each
of the  Equity  Income  Fund and the  Special  Opportunities  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 and the  Special  Opportunities  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.
<PAGE>

STRIPPED  MORTGAGE-BACKED  SECURITIES:  Each of the Equity  Income  Fund and the
Special  Opportunities  Fund may  invest a portion  of its  assets  in  stripped
mortgage-backed  securities  ("SMBS") which are derivative  multiclass  mortgage
securities issued by agencies or instrumentalities of the U.S. Government, or by
private  originators of, or investors in, mortgage loans,  including savings and
loan institutions, mortgage banks, commercial banks and investment banks.

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

LOANS AND OTHER  DIRECT  INDEBTEDNESS:  Each of the Equity  Income  Fund and the
Special Opportunities 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.
<PAGE>

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.
<PAGE>

MORTGAGE PASS-THROUGH SECURITIES: Each of the Equity Income Fund and the Special
Opportunities  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
security generally will decline; however, when interest rates are declining, the
value of mortgage  pass-through  securities  with  prepayment  features  may not
increase as much as that of other fixed-income securities.

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

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."  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.
<PAGE>

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
seller/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  Fund  may  also  buy  mortgage-related  securities  without
insurance or guarantees.

ZERO COUPON BONDS, DEFERRED INTEREST BONDS AND PIK BONDS: The Equity Income Fund
and the Special  Opportunities  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
<PAGE>

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

The 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.

No  securities  will be sold short if,  after  effect is given to any such short
sale,  the total market value of all  securities  sold short would exceed 25% of
the value of the  Fund's net  assets.  The Fund  similarly  will limit its short
sales  of the  securities  of any  single  issuer  if the  market  value  of the
securities  that have been sold short by the Fund would  exceed two percent (2%)
of the value of the  Fund's net assets or if such  securities  would  constitute
more than two percent (2%) of any class of the issuer's securities.
<PAGE>

Whenever the Fund engages in short sales, its custodian  segregates an amount of
cash or U.S.  Government  securities  equal to the  difference  between  (a) the
market value of the  securities  sold short at the time they were sold short and
(b) any cash or U.S.  Government  securities  required to be deposited  with the
broker in  connection  with the short sale (not  including the proceeds from the
short sale). The segregated assets are marked to market daily,  provided that at
no time will the  amount  deposited  by the  Fund's  custodian  plus the  amount
deposited with the broker be less than the market value of the securities at the
time they were sold short.

In addition,  the Fund also may make short sales "against the box," I.E., when a
security  identical to one owned by the Fund is borrowed and sold short.  If the
Fund  enters into a short sale  against  the box,  it is  required to  segregate
securities  equivalent  in kind and  amount  to the  securities  sold  short (or
securities  convertible or exchangeable into such securities) and is required to
hold such securities  while the short sale is  outstanding.  The Fund will incur
transaction costs, including interest, in connection with opening,  maintaining,
and closing short sales against the box.

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 or coupon rate is determined  by reference to a specific  instrument or
statistic.  Gold-indexed  securities,  for  example,  typically  provide  for  a
maturity value that depends on the price of gold,  resulting in a security whose
price  tends  to rise and  fall  together  with  gold  prices.  Currency-indexed
securities typically are short-term to  intermediate-term  debt securities whose
maturity  values or interest  rates are determined by reference to the values of
one or more specified foreign currencies,  and may offer higher yields than U.S.
dollar-denominated securities of equivalent issuers. Currency-indexed securities
may be positively  or  negatively  indexed;  that is, their  maturity  value may
increase when the specified  currency value  increases,  resulting in a security
that performs similarly to a foreign-denominated  instrument,  or their maturity
value may decline  when  foreign  currencies  increase,  resulting in a security
whose price  characteristics  are similar to a put on the  underlying  currency.
Currency-indexed  securities may also have prices that depend on the values of a
number of different foreign currencies relative to each other.

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

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

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

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

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

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

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

A call  option  written  by a Fund is  "covered"  if the Fund owns the  security
underlying  the call or has an  absolute  and  immediate  right to acquire  that
security  without   additional  cash   consideration  (or  for  additional  cash
consideration  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.
<PAGE>

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.
<PAGE>

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

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

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.
<PAGE>

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 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.
<PAGE>

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.
<PAGE>

Yield  curve  options  may be used for the same  purposes  as other  options  on
securities.  Specially,  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.

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-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.
<PAGE>

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 and
the Special  Opportunities  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.
<PAGE>

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 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.
<PAGE>

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.
<PAGE>

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
guarantee  of the  exchange  clearinghouse.  In  addition,  Options  on  Futures
Contracts  may be traded on foreign  exchanges.  A Fund may cover the writing of
call  Options on Futures  Contracts  (a)  through  purchases  of the  underlying
Futures  Contract,  (b) through  ownership  of the  instrument,  or  instruments
included  in the index,  underlying  the  Futures  Contract,  or (c) through the
holding of a call on the same Futures  Contract and in the same principal amount
as the call written where the exercise price of the call held (i) is equal to or
less than the  exercise  price of the call  written or (ii) is greater  than the
exercise  price of the call written if the  difference is 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.
<PAGE>

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.  Forward  Contracts  on  Foreign  Currency:  Each Fund may enter into
forward foreign currency exchange contracts for hedging and non-hedging purposes
(collectively,  "Forward Contracts").  Forward Contracts may be used for hedging
to  attempt  to  minimize  the  risk to the Fund  from  adverse  changes  in the
relationship  between the U.S. dollar and foreign currencies.  Each Fund intends
to enter into Forward  Contracts for hedging purposes similar to those described
above in connection with foreign currency futures  contracts.  In particular,  a
Forward Contract to sell a currency may be entered into in lieu of the sale of a
foreign  currency  futures  contract  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,  a 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. Each
Fund may also  enter  into a Forward  Contract  in order to  assure  itself of a
predetermined   exchange  rate  in  connection  with  a  fixed  income  security
denominated in a foreign currency. In addition,  the Fund may enter into Forward
Contracts for "cross hedging"  purposes (E.G., the purchase or sale of a Forward
Contract on one type of currency, as a hedge against adverse fluctuations in the
value of a  second  type of  currency).  If a  hedging  transaction  in  Forward
Contracts is  successful,  the decline in the value of portfolio  securities  or
other  assets or the  increase in the cost of  securities  or other assets to be
acquired may be offset,  at least in part,  by profits on the Forward  Contract.
<PAGE>

Nevertheless, by entering into such Forward Contracts, a 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 or natural  resources  prices.  Each
Fund does not intend, in most instances,  to hold Forward Contracts entered into
until  maturity,  at which  time they  would be  required  to  deliver or accept
delivery  of the  underlying  currency,  but  will  usually  seek to  close  out
positions in such contracts by entering into offsetting transactions, which will
serve to fix a Fund's  profit or loss based upon the value of the  contracts  at
the time the offsetting  transaction is executed.  Each Fund may also enter into
transactions  in  Forward  Contracts  for other  than  hedging  purposes,  which
presents greater profit potential but also involves increased risk. For example,
a Fund may purchase a given foreign  currency  through a Forward Contract if, in
the  judgment  of the  Adviser,  the value of such  currency is expected to rise
relative to the U.S. dollar.  Conversely, the Fund may sell the currency through
a Forward  Contract if the Adviser believes that its value will decline relative
to the dollar.

Each  Fund  entering  into such  transactions  will  profit  if the  anticipated
movements in foreign  currency  exchange  rates occurs,  which will increase its
gross income. Where exchange rates do not move in the direction or to the extent
anticipated,  however,  the Fund may sustain losses, which will reduce its gross
income. Such transactions,  therefore, could be considered speculative and could
involve significant risk of loss.

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-quality 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.  While these  contracts  are not
presently  regulated by the CFTC, the CFTC may in the future assert authority to
regulate Forward Contracts. In such event, the Fund's ability to utilize Forward
Contracts in the manner set forth above may be restricted.
<PAGE>

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.

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

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

Where the price of the underlying  obligation moves sufficiently in favor of the
holder to warrant exercise of the option,  however, and the option is exercised,
the Fund will incur a loss which may only be  partially  offset by the amount of
the premium it received.  Moreover, by writing an option, a Fund may be required
to forego the benefits which might otherwise have been obtained from an increase
in the value of portfolio  securities  or other assets or a decline in the value
of securities or assets to be acquired. In the event of the occurrence of any of
the foregoing  adverse market events,  a Fund's overall return may be lower than
if it had not engaged in the hedging transactions.
<PAGE>

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 the
daily limit on a number of consecutive trading days.
<PAGE>

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

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

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

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

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.
<PAGE>

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

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

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

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 insuring that the use of such futures is unleveraged.

RISKS OF INVESTING IN LOWER RATED BONDS

The Equity  Income Fund and the Special  Opportunities  Fund may invest in fixed
income securities, and each Fund may invest in convertible securities, rated Baa
by Moody's  Investors  Service,  Inc.  ("Moody's")  or BBB by  Standard & Poor's
Ratings Group ("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.

The Equity  Income  Fund and the Special  Opportunities  Fund may also invest in
fixed  income  securities  rated Ba or lower by Moody's or BB or lower by S&P or
Fitch and comparable unrated securities  (commonly known as "junk bonds") 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.
<PAGE>

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 Statement of Additional  Information,  means the
lesser of (i) more than 50% of the  outstanding  shares of the Trust or a series
or class,  as  applicable or (ii) 67% or more of the  outstanding  shares of the
Trust or a series or class, as applicable, present at a meeting 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;
<PAGE>

   (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.
<PAGE>

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  sale,  any  type of  futures  contract
       (including Futures Contracts), and Forward Contracts;
<PAGE>

   (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.

<PAGE>

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.

Each Fund pays the  compensation of the  non-interested  Trustees and Mr. Bailey
(who  currently  receive  a fee  of $[ ] per  year  plus  $[ ] per  meeting  and
committee   meeting  attended,   together  with  such  Trustee's   out-of-pocket
expenses),  and have 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 the interested  Trustees,
except Mr. Bailey.  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 estimated to be paid by each Fund during its current fiscal year to
non-interested Trustees and Mr. Bailey.

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 wholly owned 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,  each  dated  January  2,  1996 (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,  computed  and paid  monthly,  as
disclosed in the Prospectus under the heading "Management of the Funds."
<PAGE>

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 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.

CUSTODIAN

State Street Bank and Trust Company (the  "Custodian")  is the custodian of each
Fund's  assets.  The  Custodian's   responsibilities   include  safekeeping  and
controlling  each Fund's cash and securities,  handling the receipt and delivery
of securities,  determining income and collecting interest and dividends on each
Fund's  investments,  maintaining books of original entry for portfolio and fund
accounting and other required books and accounts,  and calculating the daily net
asset  value of each  class of  shares  of each  Fund.  The  Custodian  does not
determine the investment policies of each Fund or decide which securities a Fund
will buy or sell. Each Fund may, however,  invest in securities of the Custodian
and may deal with the  Custodian as principal in  securities  transactions.  The
Trustees  have  reviewed and approved as in the best  interests of each Fund and
the  shareholders  subcustodial  arrangements  with State  Street Bank and Trust
Company  for  securities  of each Fund  held  outside  the  United  States.  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.
<PAGE>

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 based on the
net assets of each class of shares of each Fund  computed and paid  monthly.  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).
<PAGE>

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, 1996 and will
continue in effect thereafter only if such continuance is specifically  approved
at least  annually  by the Board of  Trustees  or by vote of a  majority  of the
Trust's shares (as defined in "Investment  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.
<PAGE>

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 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.
<PAGE>

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
through such  broker-dealers,  but at present,  unless  otherwise  directed by a
Fund, a commission  higher than one charged elsewhere will not be paid to such a
firm solely because it provided such Research.  The Trustees  (together with the
Trustees of the other MFS Funds) have  directed  the Adviser to allocate a total
of $20,000 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.
<PAGE>

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 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.
<PAGE>

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 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.
<PAGE>

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  certain  limited  circumstances.  The
aggregate  withdrawals of Class B shares in any year pursuant to a SWP generally
are limited to 10% of the value of the account at the time of  establishment  of
the SWP. SWP payments  are drawn from the proceeds of share  redemptions  (which
would be a return of principal  and, if  reflecting  a gain,  would be taxable).
Redemptions  of  Class B shares  will be made in the  following  order:  (i) 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 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.
<PAGE>

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 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.
<PAGE>

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 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.  In addition,  Class C shares may be exchanged for shares of
MFS Money  Market  Fund at net asset  value.  Exchanges  will be made only after
instructions in writing or by telephone (an "Exchange Request") 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.
<PAGE>

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

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

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

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

o    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);
o    Simplified Employee Pension (SEP-IRA) Plans;
o    Retirement Plans Qualified under Section 401(k)of the Internal Revenue Code
     of 1986,  as  amended  (the  "Code");  o  403(b)  Plans  (deferred
     compensation arrangements for employees of public School systems and
     certain non-profit organizations); and
o    Certain other qualified pension and profit-sharing plans.
<PAGE>

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 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.
<PAGE>

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) may
be  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 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 which are declared in October,  November or December and paid the
following  January to  shareholders of record in such a month 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 shares  have been held for more than
twelve months and otherwise as a short-term capital gain or loss.  However,  any
loss realized upon a disposition of shares in 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 securities,  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 these securities.  In order to distribute this income and avoid a tax
on the Fund, the Fund may be required to liquidate portfolio  securities that it
might  otherwise  have  continued to hold,  potentially  resulting in additional
taxable gain or loss to the Fund.
<PAGE>

An  investment by the Equity  Income Fund or the Special  Opportunities  Fund 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 that  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, and swaps and similar 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 withheld at the source;  the Funds do not expect to be able
to pass through to shareholders Foreign tax credits with respect to such foreign
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  the  effective  rate of
foreign  tax in advance  since the amount of the  Fund's  assets to be  invested
within various countries is not known.

Dividends  and  certain  other  payments  to  persons  who are not  citizens  or
residents  of the  United  States  or U.S.  entities  ("Non-U.S.  Persons")  are
generally  subject to U.S. tax withholding at the rate of 30%. 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.

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 if
the dealer satisfies certain  criteria);  or (ii) to any insurance company which
has entered into an agreement  with the Fund and MFD that permits such insurance
company  to  purchase  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 if the dealer satisfies certain criteria.  Dealers
may from time to time be required  to meet  certain  other  criteria in order to
receive service fees.

MFD or its affiliates shall be entitled to receive any service fee payable under
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.
<PAGE>

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.

GENERAL:  Each of the  Distribution  Plans will remain in effect until August 1,
1996,  and will  continue  in  effect  thereafter  only if such  continuance  is
specifically  approved  at least  annually  by 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  Statement  of  Additional  Information,  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.
<PAGE>

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  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) total rates of return  which  represent
aggregate performance over a period or year-by-year  performance,  and which may
or may not reflect the effect of the maximum or other sales charge or CDSC.

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 for Class A
shares assume a maximum sales charge of 4.75%. The yield calculation for Class B
shares assumes no CDSC is paid.

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 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,

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.

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 three other  series.  The  Declaration  of Trust further
authorizes  the Trustees to classify or reclassify any series of shares into one
or more classes.  Pursuant thereto, the Trustees have authorized the issuance of
three classes of shares of each Fund (Class A, Class B and Class C shares). Each
share of a class of a Fund  represents  an equal  proportionate  interest in the
assets  of the  Fund  allocable  to  that  class.  Upon  liquidation  of a Fund,
shareholders  of each  class of the Fund are  entitled  to share pro rata in the
Fund's  net  assets  allocable  to such  class  available  for  distribution  to
shareholders.  The Trust  reserves  the  right to  create  and issue a number of
series and additional  classes of shares, in which case the shares of each class
of a series would  participate  equally in the  earnings,  dividends  and assets
allocable to that class of the particular series.
<PAGE>

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

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

in connection with the Securities being Registered,  the Registrant will, unless
in the  opinion  of its  counsel  the matter  has been  settled  by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.

              together as a single  class except that shares of a class may vote
              separately  on matters  affecting  only that class and shares of a
              class not affected by a matter will not vote on that matter; and

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

between MFS SERIES TRUST I, a Massachusetts business trust (the "Trust"), on  
behalf of MFS CASH RESERVE FUND (the "Fund"), a series of the Trust, and  
MASSACHUSETTS FINANCIAL SERVICES COMPANY, a Delaware corporation (the  
"Adviser"). 

                                  WITNESSETH: 

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

such investment advice and supervision as the latter may from time to time

amended from time to time (respectively, the "Declaration" and the "By-Laws"),  
to the provisions of the Investment Company Act of 1940 and the Rules,  
Regulations and orders thereunder and to the Fund's then-current Prospectus  
and Statement of Additional Information.  The Adviser shall also make  
recommendations as to the manner in which voting rights, rights to consent to  
corporate action and any other rights pertaining to the Fund's portfolio  
securities shall be exercised.  Should the Trustees at any time, however, make  
any definite determination as to the investment policy and notify the Adviser  
thereof in writing, the Adviser shall be bound by such determination for the  
period, if any, specified in such notice or until similarly notified that such  
determination shall be revoked.  The Adviser shall take, on behalf of the  
Fund, all actions which it deems necessary to implement the investment  
policies determined as provided above, and in particular to place all orders  
for the purchase or sale of portfolio securities for the Fund's account with  
brokers or dealers selected by it, and to that end, the Adviser is authorized  
as the agent of the Fund to give instructions to the Custodian of the Fund as  
to the deliveries of securities and payments of cash for the account of the  
Fund.  In connection with the selection of such brokers or dealers and the  
placing of such orders, the Adviser is directed to seek for the Fund execution  
at the most reasonable price by responsible brokerage firms at reasonably  
competitive commission rates.  In fulfilling this requirement the Adviser  
shall not be deemed to have acted unlawfully or to have breached any duty,  
created by this Agreement or otherwise, solely by reason of its having caused  
the Fund to pay a broker or dealer an amount of commission for effecting a  
securities transaction in excess of the amount of commission another broker or  
dealer would have charged for effecting that transaction, if the Adviser  
determined in good faith that such amount of commission was reasonable in  
relation to the value of the brokerage and research services provided by such  
broker or dealer, viewed in terms of either that particular transaction or the  
Adviser's overall responsibilities with respect to the Fund and to other  
clients of the Adviser as to which the Adviser exercises investment discretion.

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

ARTICLE 3.  Compensation of the Adviser.  For the services to be rendered and  
the facilities provided, the Fund shall pay to the Adviser an investment  
advisory fee computed and paid monthly at a rate equal to .55% of the Fund's  
average daily net assets for its then-current fiscal year.  Payment of the  
foregoing fee is subject to the provision that within 30 days following the  
close of any fiscal year of the Fund, the Adviser will pay to the Fund a sum  
equal to the amount by which the aggregate expenses of the Fund, but excluding  
interest, taxes, brokerage commissions and extraordinary expenses, incurred  
during such fiscal year exceed the sum of (a) 2 1/2% of the first $30 million  
of the Fund's average daily net assets, and (b) 2% of the next $70 million of  
the Fund's average daily net assets, and (c) 1 1/2% of the remaining average  
daily net assets of the Fund.  The obligation of the Adviser to reimburse the  
Fund for expenses incurred during any year may be terminated or revised at any  
time by the Adviser without the consent of the Fund by notice in writing from  
the Adviser to the Fund.  If the Adviser shall serve for less than the whole  
of any period specified in this Article 3, the compensation (including the  
expense reimbursement) payable to the Adviser with respect to the Fund will be  
prorated. 
<PAGE>

ARTICLE 4.  Covenants of the Adviser.  The Adviser agrees that it will not  
deal with itself, or with the Trustees of the Trust or the Trust's principla  
underwriter, if any, as principals in making purchases or sales of securities  
or other property for the account of the Fund, except as permitted by the  
Investment Company Act of 1940 and the Rules, Regulations or orders  
thereunder, will not take a long or short position in the shares of the Fund  
except as permitted by the Declaration and will comply with all other  
provisions of the Declaration and the By-Laws and the then-current Prospectus  
and Statement of Additional Information of the Fund relative to the Adviser  
and its Directors and officers. 

ARTICLE 5.  Limitation of Liability of the Adviser.  The Adviser shall not be  
liable for any error of judgment or mistake of law or for any loss arising out  
of any investment or for any act or omission in the execution and management  
of the Fund, except for willful misfeasance, bad faith or gross negligence in  
the performance of its duties and obligations hereunder.  As used in this  
Article 5, the term "Adviser" shall include Directors, officers and employees  
of the Adviser as well as that corporation itself. 

ARTICLE 6.  Activities of the Adviser.  The services of the Adviser to the  
Fund are not deemed to be exclusive, the Adviser being free to render  
investment advisory and/or other services to others.  The Adviser may permit  
other fund clients to use the initials "MFS" in their names.  The Fund agrees  
that if the Adviser shall for any reason no longer serve as the Adviser to the  
Fund, the Fund will change its name so as to delete the initials "MFS".  It is  
understood that the Trustees, officers and shareholders of the Trust are or  
may be or become interested in the Adviser, as Directors, officers, employees,  
or otherwise and that Directors, officers and employees of the Adviser are or  
may become similarly interested in the Fund, and that the Adviser may be or  
become interested in the Fund as a shareholder or otherwise. 

ARTICLE 7.  Duration, Termination and Amendment of this Agreement.  This  
Agreement shall become effective on the date first above written and shall  
govern the relations between the parties hereto thereafter, and shall remain  
in force until August 1, 1995 on which date it will terminate unless its  
continuance after August 1, 1995 is "specifically approved at least annually"  
(i) by the vote of a majority of the Trustees of the Trust who are not  
"interested persons" of the Trust or of the Adviser at a meeting specifically  
called for the purpose of voting on such approval, and (ii) by the Board of  
Trustees of the Trust, or by "vote of a majority of the outstanding voting  
securities" of the Fund. 

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

majority of the outstanding voting securities" of the Fund. 

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

IN WITNESS WHEREOF, the parties have caused this Agreement to be executed and

                         INVESTMENT ADVISORY AGREEMENT



INVESTMENT  ADVISORY  AGREEMENT,  dated this 1st day of September,  1993, by and
between MFS SERIES TRUST I, a  Massachusetts  business trust (the  "Trust"),  on
behalf of MFS LIFETIME MANAGED SECTORS FUND, a series of the Trust (the "Fund"),
and  MASSACHUSETTS  FINANCIAL  SERVICES  COMPANY,  a Delaware  corporation  (the
"Adviser").

                                  WITNESSETH:

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

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

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

ARTICLE 1. Duties of the Adviser.  The Adviser  shall provide the Fund with such
investment  advice and  supervision as the latter may from time to time consider
necessary  for the proper  supervision  of its funds.  The Adviser  shall act as
Adviser to the Fund and as such shall furnish continuously an investment program
and shall determine from time to time what securities  shall be purchased,  sold
or  exchanged  and  what  portion  of the  assets  of the  Fund  shall  be  held
uninvested,  subject always to the  restrictions  of the Declaration of Trust of
the Trust,  dated July 22, 1986, and By-Laws,  each as amended from time to time
(respectively,  the "Declaration"  and the "By-Laws"),  to the provisions of the
Investment Company Act of 1940 and the Rules,  Regulations and orders thereunder
and  to  the  Fund's   then-current   Prospectus  and  Statement  of  Additional
Information.  The Adviser  shall also make  recommendations  as to the manner in
which voting rights,  rights to consent to corporate action and any other rights
pertaining to the Fund's  portfolio  securities  shall be exercised.  Should the
Trustees  at any  time,  however,  make  any  definite  determination  as to the
investment  policy and notify the Adviser thereof in writing,  the Adviser shall
be bound by such  determination for the period, if any, specified in such notice
or until  similarly  notified  that such  determination  shall be  revoked.  The
Adviser shall take, on behalf of the Fund, all actions which it deems  necessary
to implement  the  investment  policies  determined  as provided  above,  and in
particular to place all orders for the purchase or sale of portfolio  securities
for the Fund's account with brokers or dealers  selected by it, and to that end,
the Adviser is authorized as the agent of the Fund to give  instructions  to the
Custodian of the Fund as to the  deliveries of  securities  and payments of cash
for the account of the Fund. In connection with the selection of such brokers or
dealers and the placing of such orders,  the Adviser is directed to seek for the
Fund execution at the most  reasonable  price by responsible  brokerage firms at
reasonably  competitive  commission  rates. In fulfilling  this  requirement the
Adviser  shall not be deemed to have acted  unlawfully  or to have  breached any
duty,  created by this  Agreement or  otherwise,  solely by reason of its having
caused the Fund to pay a broker or dealer an amount of commission  for effecting
a securities transaction in excess of the amount of commission another broker or
dealer  would have  charged  for  effecting  that  transaction,  if the  Adviser
determined  in good faith  that such  amount of  commission  was  reasonable  in
relation to the value of the  brokerage and research  services  provided by such
broker or dealer,  viewed in terms of either that particular  transaction or the
Adviser's overall responsibilities with respect to the fund and to other clients
of the Adviser as to which the Adviser exercises investment discretion.

ARTICLE 2. Allocation of Charges and Expenses.  The Adviser shall furnish at its
own expense  investment  advisory and  administrative  services,  office  space,
equipment and clerical personnel  necessary for servicing the investments of the

executive and  supervisory  personnel for managing the investments and effecting
the portfolio transactions of the Fund. The Adviser shall arrange, if desired by
the Trust,  for  Directors,  officers  and  employees of the Adviser to serve as
Trustees,  officers or agents of the Trust if duly  elected or appointed to such
positions and subject to their individual consent and to any limitations imposed
by law.  It is  understood  that  the  Fund  will  pay  all of its own  expenses
including,  without  limitation,  compensation of Trustees "not affiliated" with
the Adviser;  governmental fees; interest charges; taxes; membership dues in the
Investment  Company  Institute  allocable  to the  Fund;  fees and  expenses  of
independent auditors, of legal counsel, and of any transfer agent,  registrar or
dividend  disbursing  agent of the Fund;  expenses of repurchasing and redeeming
shares and servicing shareholder accounts;  expenses of preparing,  printing and
mailing stock certificates,  shareholder reports,  notices, proxy statements and
reports to governmental  officers and commissions;  brokerage and other expenses
connected  with the execution,  recording and  settlement of portfolio  security

and the  preparation,  printing and mailing of  prospectuses  for such  purposes
(except to the extent that any  Distribution  Agreement  to which the Trust is a
party on behalf of the Fund provides that another party is to pay some or all of
such expenses).

ARTICLE 3. Compensation of the Adviser.  For the services to be rendered and the
facilities  provided,  the Fund shall pay to the Adviser an investment  advisory
fee  computed  and paid  monthly at a rate  equal to .75% of the Fund's  average
daily net assets for its then-current  fiscal year. Payment of the foregoing fee
is subject  to the  provision  that  within 30 days  following  the close of any
fiscal  year of the Fund,  the  Adviser  will pay to the Fund a sum equal to the
amount by which the  aggregate  expenses of the Fund,  but  excluding  interest,
taxes,  brokerage commissions and extraordinary  expenses,  incurred during such
fiscal year exceed the sum of (a) 1 1/2% of the Fund's  average daily net assets
during such fiscal up to and  including  $40 million,  and (b) 1% of its average
daily  net  assets  during  such  fiscal  year in  excess  of $40  million.  The
obligation of the Adviser to reimburse the Fund for expenses incurred during any
year may be terminated or revised at any time by the Adviser without the consent
of the Fund by notice in writing  from the  Adviser to the Fund.  If the Adviser

permitted by the  Declaration,  and will comply with all other provisions of the

Additional Information of the Fund relative to the Adviser and its Directors and
officers.

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

ARTICLE 4.  Covenants of the Adviser.  The Adviser  agrees that it will not deal
with itself,  or with the Trustees of the Trust or the Trust's  distributor,  if
any, as principals in making  purchases or sales of securities or other property
for the account of the Fund,  except as permitted by the Investment  Company Act
of 1940 and the Rules, Regulations or orders thereunder, will not take a long or

August 1, 1996 is "specifically approved at least annually" (i) by the vote of a
majority of the  Trustees of the Trust who are not  "interested  persons" of the
Trust or of the  Adviser at a meeting  specifically  called  for the  purpose of
voting on such approval,  and (ii) by the Board of Trustees of the Trust,  or by
"vote of a majority of the outstanding voting securities" of the Fund.

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

majority of the outstanding voting securities" of the Fund.

The terms "specifically approved at least annually",  "vote of a majority of the
outstanding  voting  securities",   "assignment",   "affiliated   person",   and

                                    FORM OF

                         INVESTMENT ADVISORY AGREEMENT



         INVESTMENT ADVISORY AGREEMENT,  dated this 2nd day of January, 1996, by
and between MFS SERIES TRUST I, a Massachusetts business trust (the "Trust"), on
behalf of MFS  EQUITY  INCOME  FUND,  a series of the Trust  (the  "Fund"),  and
MASSACHUSETTS   FINANCIAL   SERVICES  COMPANY,   a  Delaware   corporation  (the
"Adviser").

                                  WITNESSETH:

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

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

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

         Article 1. Duties of the Adviser.  The Adviser  shall  provide the Fund
with such investment  advice and supervision as the latter may from time to time
consider  necessary for the proper  supervision of its funds.  The Adviser shall
act as Adviser to the Fund and as such shall furnish  continuously an investment
program  and  shall  determine  from  time  to time  what  securities  shall  be
purchased, sold or exchanged and what portion of the assets of the Fund shall be
held  uninvested,  subject always to the restrictions of the Trust's Amended and
Restated  Declaration  of Trust,  dated  January 6, 1995,  and By-Laws,  each as
amended from time to time  (respectively,  the "Declaration" and the "By-Laws"),
to  the  provisions  of the  Investment  Company  Act of  1940  and  the  Rules,
Regulations and orders thereunder and to the Fund's then-current  Prospectus and
Statement of Additional Information. The Adviser shall also make recommendations
as to the manner in which voting rights,  rights to consent to corporate  action
and any other rights  pertaining  to the Fund's  portfolio  securities  shall be
exercised.  Should  the  Trustees  at  any  time,  however,  make  any  definite
determination  as to the  investment  policy and notify the  Adviser  thereof in
writing,  the Adviser shall be bound by such  determination  for the period,  if
any,   specified  in  such  notice  or  until   similarly   notified  that  such
determination  shall be revoked.  The Adviser shall take, on behalf of the Fund,
all actions  which it deems  necessary  to  implement  the  investment  policies
determined  as provided  above,  and in  particular  to place all orders for the
purchase or sale of portfolio  securities for the Fund's account with brokers or
dealers  selected by it, and to that end, the Adviser is authorized as the agent
of the  Fund  to  give  instructions  to the  Custodian  of the  Fund  as to the
deliveries  of  securities  and payments of cash for the account of the Fund. In
connection with the selection of such brokers or dealers and the placing of such
orders,  the  Adviser is  directed  to seek for the Fund  execution  at the most
reasonable  price  by  responsible  brokerage  firms at  reasonably  competitive
commission  rates.  In  fulfilling  this  requirement,  the Adviser shall not be
deemed to have acted  unlawfully or to have  breached any duty,  created by this
Agreement or otherwise,  solely by reason of its having caused the Fund to pay a
broker or dealer an amount of commission for effecting a securities  transaction
in excess of the  amount  of  commission  another  broker or dealer  would  have
charged for effecting that transaction,  if the Adviser determined in good faith
that such amount of  commission  was  reasonable in relation to the value of the
brokerage  and research  services  provided by such broker or dealer,  viewed in
terms  of  either  that   particular   transaction  or  the  Adviser's   overall
responsibilities with respect to the Fund and to other clients of the Adviser as
to which the Adviser exercises investment discretion.
<PAGE>

The Adviser may from time to time enter into sub-investment  advisory agreements
with one or more  investment  advisers  with such  terms and  conditions  as the
Adviser may determine,  provided that such  sub-investment  advisory  agreements
have  been  approved  by a  majority  of the  Trustees  of the Trust who are not
"interested  persons" of the Trust,  the Adviser or the sub-adviser and by "vote
of a majority of the outstanding  voting securities" of the Fund. Subject to the
provisions  of  Article  6, the  Adviser  shall not be  liable  for any error of
judgment or mistake of law by any sub-adviser or for any loss arising out of any
investment  made by any  sub-adviser or for any act or omission in the execution
and management of the Fund by any sub-adviser.

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

         Article 3. Compensation of the Adviser. For the services to be rendered
and the  facilities  provided,  the Fund shall pay to the Adviser an  investment
advisory  fee  computed and paid monthly at an annual rate equal to 0.75% of the
Fund's average daily net assets for its then-current fiscal year. If the Adviser
shall serve for less than the whole of any period  specified  in this Article 3,
the compensation to the Adviser will be prorated.

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

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

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

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

         Article 8. Duration,  Termination and Amendment of this Agreement. This
Agreement  shall  become  effective  on the date first  above  written and shall
govern the relations between the parties hereto thereafter,  and shall remain in
force  until  January  2,  1998  on  which  date it will  terminate  unless  its
continuance  after January 2, 1998 is "specifically  approved at least annually"
(i) by the  vote  of a  majority  of the  Trustees  of the  Trust  who  are  not
"interested  persons" of the Trust or of the  Adviser at a meeting  specifically
called  for the  purpose  of voting on such  approval,  and (ii) by the Board of
Trustees  of the Trust,  or by "vote of a  majority  of the  outstanding  voting
securities" of the Fund.
<PAGE>

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

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

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

required to be maintained by Section 31(a) of the Investment Company Act of 1940
and the rules  thereunder,  which at all times will be the property of the Trust

         INVESTMENT ADVISORY AGREEMENT,  dated this 2nd day of January, 1996, by
and between MFS SERIES TRUST I, a Massachusetts business trust (the "Trust"), on
behalf of MFS  RESEARCH  GROWTH  AND  INCOME  FUND,  a series of the Trust  (the
"Fund"),  and MASSACHUSETTS  FINANCIAL SERVICES COMPANY, a Delaware  corporation
(the "Adviser").

                                  WITNESSETH:

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

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

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

         Article 1. Duties of the Adviser.  The Adviser  shall  provide the Fund
with such investment  advice and supervision as the latter may from time to time
consider  necessary for the proper  supervision of its funds.  The Adviser shall
act as Adviser to the Fund and as such shall furnish  continuously an investment
program  and  shall  determine  from  time  to time  what  securities  shall  be
purchased, sold or exchanged and what portion of the assets of the Fund shall be
held  uninvested,  subject always to the restrictions of the Trust's Amended and
Restated  Declaration  of Trust,  dated  January 6, 1995,  and By-Laws,  each as
amended from time to time  (respectively,  the "Declaration" and the "By-Laws"),
to  the  provisions  of the  Investment  Company  Act of  1940  and  the  Rules,
Regulations and orders thereunder and to the Fund's then-current  Prospectus and
Statement of Additional Information. The Adviser shall also make recommendations
as to the manner in which voting rights,  rights to consent to corporate  action
and any other rights  pertaining  to the Fund's  portfolio  securities  shall be
exercised.  Should  the  Trustees  at  any  time,  however,  make  any  definite
determination  as to the  investment  policy and notify the  Adviser  thereof in
writing,  the Adviser shall be bound by such  determination  for the period,  if
any,   specified  in  such  notice  or  until   similarly   notified  that  such
determination  shall be revoked.  The Adviser shall take, on behalf of the Fund,
all actions  which it deems  necessary  to  implement  the  investment  policies
determined  as provided  above,  and in  particular  to place all orders for the
purchase or sale of portfolio  securities for the Fund's account with brokers or
dealers  selected by it, and to that end, the Adviser is authorized as the agent
of the  Fund  to  give  instructions  to the  Custodian  of the  Fund  as to the
deliveries  of  securities  and payments of cash for the account of the Fund. In
connection with the selection of such brokers or dealers and the placing of such
orders,  the  Adviser is  directed  to seek for the Fund  execution  at the most
reasonable  price  by  responsible  brokerage  firms at  reasonably  competitive
commission  rates.  In  fulfilling  this  requirement,  the Adviser shall not be
deemed to have acted  unlawfully or to have  breached any duty,  created by this
Agreement or otherwise,  solely by reason of its having caused the Fund to pay a
broker or dealer an amount of commission for effecting a securities  transaction
in excess of the  amount  of  commission  another  broker or dealer  would  have
charged for effecting that transaction,  if the Adviser determined in good faith
that such amount of  commission  was  reasonable in relation to the value of the
brokerage  and research  services  provided by such broker or dealer,  viewed in
terms  of  either  that   particular   transaction  or  the  Adviser's   overall
responsibilities with respect to the Fund and to other clients of the Adviser as
to which the Adviser exercises investment discretion.
<PAGE>

         The Adviser may from time to time enter into sub-investment  advisory
agreements with  one  or  more  investment  advisers  with  such  terms  and
conditions  as the  Adviser may  determine,  provided  that such  sub-investment
advisory  agreements  have been  approved by a majority  of the  Trustees of the
Trust  who are  not  "interested  persons"  of the  Trust,  the  Adviser  or the
sub-adviser and by "vote of a majority of the outstanding  voting securities" of
the Fund.  Subject to the  provisions  of Article  6, the  Adviser  shall not be
liable for any error of judgment or mistake of law by any sub-adviser or for any
loss arising out of any  investment  made by any  sub-adviser  or for any act or
omission in the execution and management of the Fund by any sub-adviser.

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

         Article 3. Compensation of the Adviser. For the services to be rendered
and the  facilities  provided,  the Fund shall pay to the Adviser an  investment
advisory  fee  computed and paid monthly at an annual rate equal to 0.75% of the
Fund's average daily net assets for its then-current fiscal year. If the Adviser
shall serve for less than the whole of any period  specified  in this Article 3,
the compensation to the Adviser will be prorated.

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

         Article 5.  Covenants of the Adviser.  The Adviser  agrees that it will

Investment Company Act of 1940 and the Rules,  Regulations or orders thereunder,

permitted by the  Declaration,  and will comply with all other provisions of the
Declaration  and the By-Laws and the  then-current  Prospectus  and Statement of
Additional Information of the Fund relative to the Adviser and its Directors and
officers.

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

         Article 7.  Activities  of the Adviser.  The services of the Adviser to
the Fund are not  deemed  to be  exclusive,  the  Adviser  being  free to render

understood that the Trustees,  officers and shareholders of the Trust are or may
be or become interested in the Adviser, as Directors,  officers,  employees,  or
otherwise and that  Directors,  officers and employees of the Adviser are or may
become similarly  interested in the Trust, and that the Adviser may be or become
interested in the Fund as a shareholder or otherwise.

         Article 8. Duration,  Termination and Amendment of this Agreement. This
Agreement  shall  become  effective  on the date first  above  written and shall
govern the relations between the parties hereto thereafter,  and shall remain in

securities" of the Fund, or by the Adviser,  in each case on not more than sixty
days' nor less than  thirty  days'  written  notice  to the  other  party.  This
Agreement shall automatically terminate in the event of its "assignment".

of  Massachusetts.  The Adviser  acknowledges that the obligations of or arising

officers, employees, agents or shareholders individually, but are binding solely

                         INVESTMENT ADVISORY AGREEMENT



         INVESTMENT ADVISORY AGREEMENT,  dated this 2nd day of January, 1996, by
and between MFS SERIES TRUST I, a Massachusetts business trust (the "Trust"), on
behalf  of MFS CORE  GROWTH  FUND,  a series  of the  Trust  (the  "Fund"),  and
MASSACHUSETTS   FINANCIAL   SERVICES  COMPANY,   a  Delaware   corporation  (the
"Adviser").

                                  WITNESSETH:

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

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

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

         Article 1. Duties of the Adviser.  The Adviser  shall  provide the Fund
with such investment  advice and supervision as the latter may from time to time
consider  necessary for the proper  supervision of its funds.  The Adviser shall
act as Adviser to the Fund and as such shall furnish  continuously an investment
program  and  shall  determine  from  time  to time  what  securities  shall  be
purchased, sold or exchanged and what portion of the assets of the Fund shall be
held  uninvested,  subject always to the restrictions of the Trust's Amended and
Restated  Declaration  of Trust,  dated  January 6, 1995,  and By-Laws,  each as
amended from time to time  (respectively,  the "Declaration" and the "By-Laws"),
to  the  provisions  of the  Investment  Company  Act of  1940  and  the  Rules,
Regulations and orders thereunder and to the Fund's then-current  Prospectus and
Statement of Additional Information. The Adviser shall also make recommendations
as to the manner in which voting rights,  rights to consent to corporate  action
and any other rights  pertaining  to the Fund's  portfolio  securities  shall be
exercised.  Should  the  Trustees  at  any  time,  however,  make  any  definite
determination  as to the  investment  policy and notify the  Adviser  thereof in
writing,  the Adviser shall be bound by such  determination  for the period,  if
any,   specified  in  such  notice  or  until   similarly   notified  that  such
determination  shall be revoked.  The Adviser shall take, on behalf of the Fund,
all actions  which it deems  necessary  to  implement  the  investment  policies
determined  as provided  above,  and in  particular  to place all orders for the
purchase or sale of portfolio  securities for the Fund's account with brokers or
dealers  selected by it, and to that end, the Adviser is authorized as the agent
of the  Fund  to  give  instructions  to the  Custodian  of the  Fund  as to the
deliveries  of  securities  and payments of cash for the account of the Fund. In
connection with the selection of such brokers or dealers and the placing of such
orders,  the  Adviser is  directed  to seek for the Fund  execution  at the most
reasonable  price  by  responsible  brokerage  firms at  reasonably  competitive
commission  rates.  In  fulfilling  this  requirement,  the Adviser shall not be
deemed to have acted  unlawfully or to have  breached any duty,  created by this
Agreement or otherwise,  solely by reason of its having caused the Fund to pay a
broker or dealer an amount of commission for effecting a securities  transaction
in excess of the  amount  of  commission  another  broker or dealer  would  have
charged for effecting that transaction,  if the Adviser determined in good faith
that such amount of  commission  was  reasonable in relation to the value of the
brokerage  and research  services  provided by such broker or dealer,  viewed in
terms  of  either  that   particular   transaction  or  the  Adviser's   overall
responsibilities with respect to the Fund and to other clients of the Adviser as
to which the Adviser exercises investment discretion.
<PAGE>

         The Adviser may from time to time enter into sub-investment  advisory
agreements  with  one or more  investment  advisers  with  such  terms  and
conditions  as the  Adviser may  determine,  provided  that such  sub-investment
advisory  agreements  have been  approved by a majority  of the  Trustees of the
Trust  who are  not  "interested  persons"  of the  Trust,  the  Adviser  or the
sub-adviser and by "vote of a majority of the outstanding  voting securities" of
the Fund.  Subject to the  provisions  of Article  6, the  Adviser  shall not be
liable for any error of judgment or mistake of law by any sub-adviser or for any
loss arising out of any  investment  made by any  sub-adviser  or for any act or
omission in the execution and management of the Fund by any sub-adviser.

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

         Article 3. Compensation of the Adviser. For the services to be rendered
and the  facilities  provided,  the Fund shall pay to the Adviser an  investment
advisory  fee  computed and paid monthly at an annual rate equal to 0.75% of the
Fund's average daily net assets for its then-current fiscal year. If the Adviser
shall serve for less than the whole of any period  specified  in this Article 3,
the compensation to the Adviser will be prorated.

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

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

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

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

         Article 8. Duration,  Termination and Amendment of this Agreement. This
Agreement  shall  become  effective  on the date first  above  written and shall
govern the relations between the parties hereto thereafter,  and shall remain in
force  until  January  2,  1998  on  which  date it will  terminate  unless  its
continuance  after January 2, 1998 is "specifically  approved at least annually"
(i) by the  vote  of a  majority  of the  Trustees  of the  Trust  who  are  not
"interested  persons" of the Trust or of the  Adviser at a meeting  specifically
called  for the  purpose  of voting on such  approval,  and (ii) by the Board of
Trustees  of the Trust,  or by "vote of a  majority  of the  outstanding  voting
securities" of the Fund.
<PAGE>

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

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

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

separate  and  distinct  and  that the  obligations  of or  arising  out of this
Agreement are binding  solely upon the assets or property of the series on whose

advisory  fee  computed and paid monthly at an annual rate equal to 0.75% of the

         Article 4. Special Services.. Should the Trust have occasion to request
the  Adviser  to perform  services  not herein  contemplated  or to request  the
Adviser to arrange for the services of others, the Adviser wil act for the Trust

for the Adviser's  services to be agreed upon with respect to each such occasion
as it arises.

         Article 5.  Covenants of the Adviser.  The Adviser  agrees that it will
not  deal  with  itself,  or with  the  Trustees  of the  Trust  or the  Trust's

Investment Company Act of 1940 and the Rules,  Regulations or orders thereunder,

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

         Article 7.  Activities  of the Adviser.  The services of the Adviser to
the Fund are not  deemed  to be  exclusive,  the  Adviser  being  free to render

understood that the Trustees,  officers and shareholders of the Trust are or may
be or become interested in the Adviser, as Directors,  officers,  employees,  or
otherwise and that  Directors,  officers and employees of the Adviser are or may
become similarly  interested in the Trust, and that the Adviser may be or become
interested in the Fund as a shareholder or otherwise.

         Article 8. Duration,  Termination and Amendment of this Agreement. This
Agreement  shall  become  effective  on the date first  above  written and shall

"interested  persons" of the Trust or of the  Adviser at a meeting  specifically
called  for the  purpose  of voting on such  approval,  and (ii) by the Board of
Trustees  of the Trust,  or by "vote of a  majority  of the  outstanding  voting
securities" of the Fund.

penalty by the  Trustees  or by "vote of a majority  of the  outstanding  voting

days' nor less than  thirty  days'  written  notice  to the  other  party.  This

Declaration of Trust is on file with the Secretary of State of the  Commonwealth
of  Massachusetts.  The Adviser  acknowledges that the obligations of or arising
out of  this  Agreement  are  not  binding  upon  any of the  Trust's  trustees,
officers, employees, agents or shareholders individually, but are binding solely

form acceptable to the Trust and in compliance with the rules and regulations of

                         INVESTMENT ADVISORY AGREEMENT



         INVESTMENT ADVISORY AGREEMENT,  dated this 2nd day of January, 1996, by
and between MFS SERIES TRUST I, a Massachusetts business trust (the "Trust"), on
behalf of MFS SPECIAL  OPPORTUNITIES  FUND, a series of the Trust (the  "Fund"),
and  MASSACHUSETTS  FINANCIAL  SERVICES  COMPANY,  a Delaware  corporation  (the
"Adviser").

                                  WITNESSETH:

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

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

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

         Article 1. Duties of the Adviser.  The Adviser  shall  provide the Fund
with such investment  advice and supervision as the latter may from time to time
consider  necessary for the proper  supervision of its funds.  The Adviser shall
act as Adviser to the Fund and as such shall furnish  continuously an investment
program  and  shall  determine  from  time  to time  what  securities  shall  be
purchased, sold or exchanged and what portion of the assets of the Fund shall be
held  uninvested,  subject always to the restrictions of the Trust's Amended and
Restated  Declaration  of Trust,  dated  January 6, 1995,  and By-Laws,  each as
amended from time to time  (respectively,  the "Declaration" and the "By-Laws"),
to  the  provisions  of the  Investment  Company  Act of  1940  and  the  Rules,
Regulations and orders thereunder and to the Fund's then-current  Prospectus and
Statement of Additional Information. The Adviser shall also make recommendations
as to the manner in which voting rights,  rights to consent to corporate  action
and any other rights  pertaining  to the Fund's  portfolio  securities  shall be
exercised.  Should  the  Trustees  at  any  time,  however,  make  any  definite
determination  as to the  investment  policy and notify the  Adviser  thereof in
writing,  the Adviser shall be bound by such  determination  for the period,  if
any,   specified  in  such  notice  or  until   similarly   notified  that  such
determination  shall be revoked.  The Adviser shall take, on behalf of the Fund,
all actions  which it deems  necessary  to  implement  the  investment  policies
determined  as provided  above,  and in  particular  to place all orders for the
purchase or sale of portfolio  securities for the Fund's account with brokers or
dealers  selected by it, and to that end, the Adviser is authorized as the agent
of the  Fund  to  give  instructions  to the  Custodian  of the  Fund  as to the
deliveries  of  securities  and payments of cash for the account of the Fund. In
connection with the selection of such brokers or dealers and the placing of such
orders,  the  Adviser is  directed  to seek for the Fund  execution  at the most
reasonable  price  by  responsible  brokerage  firms at  reasonably  competitive
commission  rates.  In  fulfilling  this  requirement,  the Adviser shall not be
deemed to have acted  unlawfully or to have  breached any duty,  created by this
Agreement or otherwise,  solely by reason of its having caused the Fund to pay a
broker or dealer an amount of commission for effecting a securities  transaction
in excess of the  amount  of  commission  another  broker or dealer  would  have
charged for effecting that transaction,  if the Adviser determined in good faith
that such amount of  commission  was  reasonable in relation to the value of the
brokerage  and research  services  provided by such broker or dealer,  viewed in
terms  of  either  that   particular   transaction  or  the  Adviser's   overall
responsibilities with respect to the Fund and to other clients of the Adviser as
to which the Adviser exercises investment discretion.
<PAGE>

         The Adviser may from time to time enter into sub-investment  advisory
agreements  with  one or more  investment  advisers  with  such  terms  and
conditions  as the  Adviser may  determine,  provided  that such  sub-investment
advisory  agreements  have been  approved by a majority  of the  Trustees of the
Trust  who are  not  "interested  persons"  of the  Trust,  the  Adviser  or the
sub-adviser and by "vote of a majority of the outstanding  voting securities" of
the Fund.  Subject to the  provisions  of Article  6, the  Adviser  shall not be
liable for any error of judgment or mistake of law by any sub-adviser or for any
loss arising out of any  investment  made by any  sub-adviser  or for any act or
omission in the execution and management of the Fund by any sub-adviser.

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

         Article 3. Compensation of the Adviser. For the services to be rendered
and the  facilities  provided,  the Fund shall pay to the Adviser an  investment
advisory  fee  computed and paid monthly at an annual rate equal to 0.75% of the
Fund's average daily net assets for its then-current fiscal year. If the Adviser
shall serve for less than the whole of any period  specified  in this Article 3,
the compensation to the Adviser will be prorated.

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

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

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

         Article 7.  Activities  of the Adviser.  The services of the Adviser to
the Fund are not  deemed  to be  exclusive,  the  Adviser  being  free to render
investment  advisory  and/or  other  services to others.  The Adviser may permit
other fund  clients to use the initials  "MFS" in their  names.  The Fund agrees

Fund,  the Fund will change its name so as to delete the  initials  "MFS." It is
understood that the Trustees,  officers and shareholders of the Trust are or may

otherwise and that  Directors,  officers and employees of the Adviser are or may
become similarly  interested in the Trust, and that the Adviser may be or become

Agreement  shall  become  effective  on the date first  above  written and shall
govern the relations between the parties hereto thereafter,  and shall remain in
force  until  January  2,  1998  on  which  date it will  terminate  unless  its

MFS Lifetime  Managed Sectors Fund (the "Fund") has adopted this Retirement Plan
for Non-Interested  Person Trustees (the "Plan").  The Plan has been established

1.       DEFINITIONS

         The following terms shall have the following meanings:

         Accrued  Benefit:  A benefit  which is equal to the  Normal  Retirement
Benefit  calculated  using an Independent  Trustee's Years of Service and Annual
Compensation as of the determination date.

         Actuarial  Equivalent:  A  benefit  equal  in  value,  based  on (a) an
interest  rate equal to the  immediate  annuity  rate  published  by the Pension
Guaranty Corporation for the January of the Plan Year of calculation and (b) the
1983 Individual Annuity Mortality Tables for Males.

         Annual  Compensation:  The average of the total compensation  (retainer
and meeting fees)  received by an  Independent  Trustee  during each of the last
three Plan Years  preceding  his  termination  of  services as such for which he
served  either as an  Independent  Trustee or a  Nonaffiliated  Trustee  for the
entire year;  provided,  that if an Independent Trustee served as an Independent
Trustee  and/or a  Nonaffiliated  Trustee  for fewer  than three full Plan Years
prior to his  termination  of  services,  there shall be taken into  account his
annualized  compensation  for the one or more most recent partial Plan Years (if
any) for which he served as an Independent  Trustee or a  Nonaffiliated  Trustee
that,  when  aggregated  with his full Plan  Years,  does not exceed  three Plan
Years.

         Disability:  Disability as defined in ss.22(e)(3) of the Internal
Revenue Code of 1986, as amended.

Financial Services Company ("MFS") or MFS Financial Services, Inc. ("FSI").

         Nonaffiliated  Trustee:  A  Trustee  of the  Fund  who has no  material
business or professional  relationship with the Fund,  Lifetime,  MFS or FSI and
who is subject to being declared an "interested  person" solely by reason of his
relationship  with the Fund,  Lifetime,  MFS or FSI during the two most recently
completed fiscal years of the Fund.
<PAGE>

         Normal Retirement  Benefit: An annual benefit at Normal Retirement Date
equal to 5% of an Independent  Trustee's Annual  Compensation  multiplied by the
Independent  Trustee's  whole Years of Service,  up to a maximum of ten Years of
Service, payable in the Normal Form of Benefit, as defined in ss.3(g).

         Normal Retirement Date:  The later of December 31 of the Plan Year in
which an Independent Trustee attains age 75 or December 31, 1992.

         Plan Year:  January 1 through December 31.

         Retirement:  Termination  of service of an  Independent  Trustee  after
having  completed  at least five Years of Service  and having  attained  age 62,
other than:  (1) any  termination  by reason of death;  (ii) any  termination by
reason of  Disability,  provided  that any  Independent  Trustee  who  suffers a
Disability and who has otherwise satisfied the requirements for Retirement shall
have the right to elect whether his termination is by reason of Retirement or by
reason of Disability;  or (iii) any  termination  resulting from the Independent
Trustee's willful misfeasance, bad faith, gross negligence or reckless disregard
of the duties  involved  in the  conduct of the  office of  Independent  Trustee
("Misconduct").

         Year of  Service:  A Plan  Year  during  which an  Independent  Trustee

Independent Trustee.

2.       ELIGIBILITY

         No Trustee of the Fund shall be eligible to  participate in the Plan or
be  entitled to any rights or benefits  hereunder  until the Trustee  becomes an
Independent Trustee. Each individual who completes any service as an Independent
Trustee on or after the Effective  Date of this Plan,  and who so elects in such
manner as the  Committee  determines  from  time to time,  will be  eligible  to
participate in the Plan.

3.       RETIREMENT DATE; AMOUNT OF BENEFIT

         (a) Retirement.  Each Independent Trustee shall retire on that
Independent Trustee's Normal Retirement Date, if he has not previously ceased
to perform services as an Independent Trustee.  Each retired Independent
Trustee is referred to as a "Retired Trustee".

         (b) Normal Retirement Benefit.  Upon an Independent Trustee's
Retirement on his Normal Retirement Date, the Independent Trustee shall
receive, commencing on his Normal Retirement Date, his Normal Retirement
Benefit.

Early  Retirement  Benefit  commencing  on the  Independent  Trustee's  date  of
Retirement.  The benefit payable on an Independent  Trustee's  early  Retirement
shall be his  Accrued  Benefit  reduced by 3% for every year that  payment of an
Early Retirement Benefit precedes that Trustee's Normal Retirement Date.
<PAGE>

         (d) Deferred Termination  Benefit. If an Independent  Trustee's service
as such terminates,  other than (i) termination as a result of his Misconduct or
(ii)  termination  that  constitutes  termination  by reason of his  Retirement,
Disability or death,  after he has completed at least five Years of Service,  he
shall  receive,  commencing  on the date he attains age 62, his Accrued  Benefit
reduced by 39%.

         (e) Disability  Benefit.  If an Independent  Trustee's  service as such
terminates  by reason of his  Disability  and,  if the  Independent  Trustee  is
eligible for  Retirement,  he elects that his termination be treated as being by
reason of  Disability,  he shall  receive his Accrued  Benefit  paid for the one
hundred twenty (120) months immediately following the month in which his service
so terminates.  In the event the Independent Trustee dies before he has received
one hundred twenty (120) payments,  monthly payments in the same amount shall be
paid to his beneficiary until the number of payments to the Independent  Trustee
plus the number of payments to the  beneficiary  equal one hundred  twenty (120)
payments.

         (f) Death Benefit.  Each Independent  Trustee who elects to participate
in this  Plan  shall  designate  a  beneficiary  in such  form as the  Committee
approves  from time to time to receive any benefits  payable  under this Plan in
the event of his death. In the event there is no validly designated  beneficiary
in existence on the date of an  Independent  Trustee's  death,  his  beneficiary
shall be his surviving spouse,  if any, or if none, his estate.  The beneficiary
of an  Independent  Trustee who dies during  service,  and with  respect to whom
benefit  payments  have not  commenced,  shall be entitled  to that  Independent
Trustee's  Accrued  Benefit  paid  for  the  one  hundred  twenty  (120)  months
immediately following death.

         (g)  Form of  Benefit.  Except  as  otherwise  provided  in this  ss.3,
benefits  payable  under  this ss.3  shall be  payable  in the form of a monthly
annuity for the life of the Independent Trustee, and, if the Independent Trustee
dies before he has received one hundred twenty (120) payments,  monthly payments
in the same  amount  shall be  payable  to his  beneficiary  until the number of
payments  to  the  Independent  Trustee  plus  the  number  of  payments  to the
beneficiary  equal one  hundred  twenty  (120)  payments  (the  "Normal  Form of
Benefit"). However, notwithstanding any other provision of this Section 3 to the
contrary,  if an Independent Trustee's beneficiary is entitled to payments under
this Plan upon the  Independent  Trustee's  death,  then (i) if the  Independent
Trustee's  beneficiary is his estate, the lump sum Actuarial  Equivalent present
value of those payments shall be paid to the estate in a single lump sum as soon
as administratively  reasonable  following the Independent  Trustee's death, and
(ii) if the  Independent  Trustee's  beneficiary  is other than his estate,  the
Committee in its sole discretion may direct that the Actuarial  Equivalent value
of those  payments  be paid in such form other  than the Normal  Form of Benefit
(including without limitation a lump sum) as it determines.
<PAGE>

4.       PAYMENT OF BENEFIT; ALLOCATION OF COSTS

         The Fund is responsible for the payment of the benefits, as well as all
expenses  of  administration  of the  Plan,  including  without  limitation  all
accounting,  legal and actuarial fees and expenses.  The obligations of the Fund
to pay such  benefits and expenses  will not be secured or funded in any manner,
and the  obligations  will not have any preference over the lawful claims of the
Fund's  creditors  and  shareholders.  The Fund shall be under no  obligation to
segregate any assets for the purpose of providing  retirement  benefits pursuant
to this Plan,  and to the extent  that any  Independent  Trustee or  beneficiary
acquires  a right to  receive a benefit  under the  Plan,  such  right  shall be
limited to that of a recipient of an unfunded,  unsecured promise to pay amounts
in the future and such  person's  position with respect to such amounts shall be
that of a general  unsecured  creditor of the Fund.  To the extent that the Fund
consists  of one or  more  separate  portfolios,  costs  and  expenses  will  be
allocated  among  the  portfolios  by the  Board of  Trustees  of the Fund  (the
"Board") in a manner that is  determined  by the Board to be fair and  equitable
under the circumstances.

5.       ADMINISTRATION

         (a) The Committee. Any question involving entitlement to payments under
or the  interpretation  or  administration  of the Plan  will be  referred  to a
committee (the  "Committee")  of Independent  Trustees  designated by the Board.
Except as otherwise provided herein, the Committee will make all interpretations
and  determinations  necessary or desirable for the Plan's  administration,  and
such interpretations and determinations will be final and conclusive.

         (b) Powers of the  Committee.  The Committee  will represent and act on
behalf of the Fund in respect of the Plan and,  subject to the other  provisions
of the  Plan,  the  Committee  may  adopt,  amend  or  repeal  by-laws  or other
regulations,  relating  to the  administration  of the Plan,  the conduct of the
Committee's affairs, its rights or powers or the rights or powers of its members
or of the Board. The Committee will report to the Board from time to time on its
activities  in respect of the Plan.  The  Committee or persons  designated by it
will cause such records to be kept as may be necessary for the administration of
the Plan.

6.       MISCELLANEOUS PROVISIONS

         (a) Rights Not Assignable.  The right to receive any payment
under the Plan may not be transferred, assigned, pledged or otherwise
alienated.

         (b) Amendment,  etc. The Committee,  with the concurrence of the Board,
may at any time amend or terminate  the Plan or waive any provision of the Plan,
provided that no amendment,  termination  or waiver will impair the rights of an
Independent  Trustee to receive upon  Retirement  the payments  which would have
been  made  to that  Independent  Trustee  had  there  been  no such  amendment,
termination or waiver (based upon that Independent Trustee's Years of Service to
the date of such  amendment,  termination  or  waiver) or the rights of a former
Independent  Trustee or Retired  Trustee to receive  any  benefit  due under the
Plan,  without  the  consent of such  present or former  Independent  Trustee or
Retired Trustee,  as the case may be. A present or former Independent Trustee or
Retired  Trustee may elect to waive  receipt of his  benefit by so advising  the
Committee.
<PAGE>

             Notwithstanding  any  provision of this Plan to the  contrary,
however,  in the event of the sale of all or substantially  all of the assets of
the Fund,  the  liquidation  or  dissolution of the Fund, or any merger or other
similar reorganization of the Fund that the Fund does not survive:

                  (i) if although the Fund does not survive there is a surviving
entity,  all rights and benefits  (including without limitation those of Retired
Trustees)  under the Plan shall  cease upon  consummation  of such  transaction,
unless,  and only to the extent that,  the board of trustees  (or other  similar
governing  body) of the  surviving  entity  agrees to assume the Plan  and/or to
provide any such rights or benefits; and

                  (ii) if there is no surviving entity, the Board shall have the
right to take  specific  action to terminate the Plan and/or to cause any or all
rights and benefits  (including  without  limitation those of Retired  Trustees)
under the Plan to cease as of the date of such event but,  in the absence of any
such specific  action,  the lump sum Actuarial  Equivalent  present value of the
Accrued Benefit of each present or former Independent Trustee or Retired Trustee
(or beneficiary thereof) who on the date of liquidation is receiving or entitled
to receive a benefit  under the Plan or would be  entitled  to receive a benefit
under the Plan  based on his actual or deemed  termination  of service as of the
date of such liquidation shall be paid to such person.

         (c) No Right to Re-election.  Nothing in the Plan will create
any obligation on the part of the Board to nominate any Independent Trustee
for re-election.

         (d) Vacancies.  Although the Board will retain the right to increase or
decrease its size,  it shall be the general  policy of the Board to replace each
person  who  ceases  to serve  as an  Independent  Trustee  by  selecting  a new
Independent Trustee from candidates duly proposed.

         (e)  Consulting.  Each Retired Trustee may render such services for the
Fund,  for such  compensation,  as may be agreed  upon from time to time by such
Trustee and the Board of the Fund.

         (f)  Construction.  Whenever any masculine  terminology is used in this
Plan,  it shall be taken to include the feminine,  unless the context  otherwise
indicates.  The titles and headings included herein are for convenience only and
shall not be  construed as in any way  affecting  or modifying  the text of this
Plan,  which text shall  control.  This Plan shall be construed and regulated in
accordance  with the laws of The  Commonwealth of  Massachusetts,  except to the
extent such state law is preempted by federal law.

         (g) Effective Date.  This Plan will become effective on January
1, 1991 (the "Effective Date").

Massachusetts  hereinafter  called the "Trust",  and State Street Bank and Trust

cash it desires to be held  outside  the United  States  (collectively  "foreign
securities"),  subject  to the terms of  Article 3 hereof.  The Trust  agrees to
deliver to the Custodian all  securities  and cash owned by it, and all payments
of income,  payments of principal or capital  distributions  received by it with
respect to all  securities  owned by the Trust  from time to time,  and the cash

         Upon  receipt of "Proper  Instructions"  (within the meaning of Article
5), the Custodian shall from time to time employ one or more sub-custodians, but
only in  accordance  with an  applicable  vote by the Board of  Trustees  of the
Trust, and provided that, except as expressly  provided in Article 3 hereof, the
Custodian shall have no more or less responsibility or liability to the Trust on
account of any actions or omissions  of any  subcustodian  so employed  than any
such subcustodian has to the Custodian.

2.       Duties of the Custodian with Respect to Property of the Trust Held By

Custodian and shall be withdrawable by the Custodian only in that capacity.

securities  held hereunder to which the Trust shall be entitled either by law or
pursuant to custom in the  securities  business,  and shall  collect on a timely
basis all income and other payments with respect to bearer securities if, on the
date  of  payment  by the  issuer,  such  domestic  securities  are  held by the

Trust's custodian account. Without limiting the generality of the foregoing, the
Custodian  shall  detach and present  for  payment all coupons and other  income
items  requiring  presentation  as and when they  become  due and shall  collect
interest when due on domestic securities held hereunder. Income due the Trust on
domestic  securities loaned pursuant to the provisions of Section 2.2 (10) shall
be the  responsibility  of the  Trust.  The  Custodian  will  have  no  duty  or
responsibility  in  connection  therewith,  other than to provide the Trust with
such  information  or data as may be  necessary to assist the Trust in arranging
for the timely  delivery  to the  Custodian  of the income to which the Trust is
properly entitled.

                        AMENDMENT TO CUSTODIAN CONTRACT


Amendment to Custodian  Contract  between MFS Managed  Sectors Trust, a business
trust organized and existing under the laws of Massachusetts, having a principal
place  of  business  at  200  Berkeley  Street,   Boston,   Massachusetts  02116
(hereinafter  called the  "Fund"),  and State Street Bank and Trust  Company,  a
Massachusetts  trust  company,  having its  principal  place of  business at 225
Franklin  Street,   Boston,   Massachusetts   02110   (hereinafter   called  the
"Custodian").

WHEREAS:  The Fund and the Custodian are parties to a Custodian Contract dated
January 28, 1988 (the "Custodian Contract") ;

WHEREAS:  The Fund  desires  that the  Custodian  issue a letter of credit  (the
"Letter  of  Credit")  on  behalf  of the Fund  for the  benefit  of ICI  Mutual
Insurance  Company (the "Company") in accordance  with the Continuing  Letter of
Credit and Security  Agreement and that the Fund's  obligations to the Custodian
with respect to the Letter of Credit shall be fully  collateralized at all times
while the Letter of Credit is  outstanding  by, among other  things,  segregated
assets of the Fund equal to 125% of the face  amount to the amount of the Letter
of Credit;

WHEREAS:  the Custodian Contract provides for the establishment of segregated
accounts for proper Fund purposes upon Proper Instructions (as defined in the
Custodian Contract); and

WHEREAS:  The Fund and the Custodian desire to establish a segregated account
to hold the collateral for the Fund's obligations to the Custodian with
respect to the Letter of Credit and to amend the Custodian Contract to provide
for the establishment and maintenance thereof;

WITNESSETH:  That in consideration of the mutual covenants and agreements
hereinafter contained, the parties hereto hereby amend the Custodian Contract
as follows:

         1.  Capitalized terms used herein without definition shall have
the meanings ascribed to them in the Custodian Contract.

         2.  The Fund hereby instructs the Custodian to establish and maintain a
segregated account (the "Letter of Credit Custody Account") for and in behalf of
the Fund as contemplated by Section 2.13(iv) for the purpose of  collateralizing
the Fund's obligations under this Amendment to the Custodian Contract.

         3.  The Fund shall deposit with the Custodian and the Custodian  shall
hold in the Letter of Credit Custody  Account cash, U.S.  government  securities
and  other  high-grade  debt  securities  owned  by the Fund  acceptable  to the
Custodian  (collectively  "Collateral  Securities")  equal  to 125% of the  face
amount to the amount which the Company may draw under the Letter of Credit. Upon
receipt of such Collateral  Securities in the Letter of Credit Custody  Account,
the Custodian shall issue the Letter of Credit to the Company.
<PAGE>

         4.  The fund hereby grants to the Custodian a security interest in the
Collateral  Securities from time to time in the Letter of Credit Custody Account
(the  "Collateral")  to secure the performance of the Fund's  obligations to the
Custodian with respect to the Letter of Credit,  including,  without limitation,
under Section  5-114(3) of the Uniform  Commercial Code. The Fund shall register
the pledge of Collateral  and execute and deliver to the  Custodian  such powers
and  instruments  of assignment as may be requested by the Custodian to evidence
and perfect the limited interest in the Collateral granted hereby.

         5.  The Collateral Securities in the Letter of Credit Custody  Account
may be  substituted or exchanged  (including  substitutions  or exchanges  which
increase or decrease the  aggregate  value of the  Collateral)  only pursuant to
Proper  Instructions  from the Fund after the Fund notifies the Custodian of the
contemplated  substitution  or  exchange  and the  Custodian  agrees  that  such
substitution or exchange is acceptable to the Custodian.

         6.  Upon any  payment  made  pursuant  to the  Letter  of Credit by the
Custodian  to the  Company,  after  notice to the  company,  the  Custodian  may
withdraw from the Letter of Credit Custody Account  Collateral  Securities in an
amount equal in value to the amount  actually so paid. The Custodian  shall have
with  respect  to the  Collateral  so  withdrawn  all of the rights of a secured
creditor under the Uniform  Commercial  Code as adopted in the  Commonwealth  of
Massachusetts  at the time of such  withdrawal  and all other rights  granted or
permitted to it under law.

         7.  The Custodian  will  transfer upon receipt all income earned on the
Collateral  to the Fund custody  account  unless the Custodian  receives  Proper
Instructions from the Fund to the contrary.

         8.  Upon the drawing  by the  Company of all  amounts  which may become
payable to it under the Letter of Credit and the  withdrawal  of all  Collateral
Securities with respect  thereto by the Custodian  pursuant to Section 6 hereof,
or upon the  termination  of the  Letter of Credit by the Fund with the  written
consent of the Company,  the Custodian shall transfer any Collateral  Securities
then remaining in the Letter of Credit  Custody  Account to another fund custody
account.

         9.  Collateral  held in the Letter of Credit  Custody  Account shall be
released only in accordance  with the  provisions of this Amendment to Custodian
Contract.  The Collateral shall at all times until withdrawn pursuant to Section
6 hereof  remain the  property  of the Fund,  subject  only to the extent of the
interest granted herein to the Custodian.

         10. Notwithstanding  any other termination of the Custodian  Contract,
the Custodian Contract shall remain in full force and effect with respect to the
Letter of Credit Custody  Account until  transfer of all  Collateral  Securities
pursuant to Section 8 hereof.
<PAGE>

         11. The Custodian shall be entitled to reasonable  compensation for its
issuance  of the Letter of Credit and for its  services in  connection  with the
Letter of Credit  Custody  Account as agreed upon from time to time  between the
Fund and the Custodian.

         12. The Custodian Contract as amended hereby, shall be governed
by, and construed and interpreted under, the laws of the Commonwealth of
Massachusetts.

         13. The parties agree to execute and deliver all such further documents
and  instruments and to take such further action as may be required to carry out
the purposes of the Custodian Contract, as amended hereby.

         14. Except as  provided in this  Amendment  to Custody  Contract,  the
Custodian  Contract shall remain in full force and effect,  without amendment or
modification,  and all  applicable  provisions  of the  Custodian  Contract,  as
amended hereby, including,  without limitation,  Section 8 thereof, shall govern
the Letter of Credit Custody  Account and the rights and obligations of the Fund
and the Custodian  under this Amendment to Custodian  Contract.  No provision of
this  Amendment to Custodian  Contract shall be deemed to constitute a waiver of
any rights of the Custodian under the Custodian Contract or under law.

IN WITNESS  WHEREOF,  each of the parties has caused this Amendment to Custodian
Contract  to be  executed  in  its  name  and  behalf  by  its  duly  authorized
representatives  and its  seal to be  hereunder  affixed  as of the  29th day of

Agreement  made as of this 1st day of October,  1989 by and between State Street
Bank and Trust Company (the "Custodian") and Lifetime Managed Sectors Trust (the
"Trust").

WHEREAS,  the Custodian and the Trust are parties to a Custodian  Contract dated
January  28,  1988  (the  "Custodian  Contract")  which  governs  the  terms and
conditions  under which the Custodian  maintains  custody of the  securities and
other assets of the Trust;

WHEREAS, the Custodian may delegate to Massachusetts  Financial Services Company
("MFS") the  performance  of certain  duties the  Custodian  would  otherwise be
obligated to perform pursuant to the Custodian Agreement;

WHEREAS, the Trust agrees to any such delegation of certain Custodian duties;

NOW  THEREFORE,  the  Custodian  and the  Trust  hereby  amend  the terms of the
Custodian Contract and mutually agree to the following:

1)       Add new Section 18 which shall read as follows:

18)      Delegation of Certain Custodian Duties to MFS.

         The Custodian may delegate to MFS the  performance of any or all of its
duties hereunder  relating to (i) accounting for investments in currency and for
financial  instruments  (including,  without  limitation,   options,  contracts,
futures contracts, options on futures contracts, options on foreign currency and
forward  foreign  currency  exchange  contracts)  and  (ii)  federal  and  state
regulatory compliance. The Custodian shall compensate MFS for the performance of
such duties at such fee or fees as MFS shall determine to be equal to MFS's cost
for  performing  such duties (the "MFS Fees").  Following its payment of the MFS
Fees to MFS, the Custodian shall recover the amount of the MFS Fees and from the
Trust on such terms as the  Custodian  and the Trust  shall  agree.  MFS assumes
responsibility  for all duties delegated to it by the Custodian pursuant to this
Section 18, and the Custodian  may rely on MFS for the accuracy and  correctness
of the accounting  information provided by MFS to the Custodian pursuant to this

terminate  this Contract in the event of the  appointment  of a  conservator  or
receiver  for the  Custodian  by the  Comptroller  of the  Currency  or upon the
happening of a like event at the direction of an appropriate  regulatory  agency
or court of competent jurisdiction.

         Upon termination of the Contract,  the Trust shall pay to the Custodian

delivered to it by or for the account of the Fund. All such Portfolio securities
will be held or  disposed  of by the Bank for,  and subject at all times to, the
instructions of the Fund pursuant to the terms of this Agreement. Subject to the

changed, canceled or not renewed.

the  portfolio  securities  held  hereunder  by or for the  account of the Fund,

executed and delivered,  to the Fund all notices,  proxies and proxy  soliciting

registered  holder of such securities (if registered  otherwise than in the name
of the Fund), but without  indicating the manner in which such proxies are to be
voted.

received  a  certified  copy  of a  resolution  of the  Board  specifically
approving  deposits of Fund assets in the Book-Entry  System,  and (ii) for each
year  following  such  approval,   the  Board  has  reviewed  and  approved  the
arrangement  and  has  not  delivered  an  Officer's  Certificate  to  the  Bank
indicating that it has withdrawn its approval:

                      1. The  Bank  may  keep  Securities  of the Fund in the
Book-Entry  System  provided that such  securities  are  represented  in an
account  ("Account")  of the Bank (or its agent) in such System  which shall not
include  any  assets of the Bank (or such  agent)  other than  assets  held as a
fiduciary, custodian, or otherwise for customers

                      2. The  records  of the  Bank  (and any
such agent) with respect to the Fund's  participation  in the Book-Entry  System
through  the Bank (or any such agent)  will  identify  by book entry  securities
belonging to the Fund which are included with other securities  deposited in the
Account and shall at all times during the regular business hours of the Bank (or
such agent) be open for  inspection by duly  authorized  officers,  employees or
agents of the Fund. Where securities are transferred to the Fund's account,  the
Bank shall also, by book entry or otherwise, identify as belonging to the Fund a
quantity of securities in fungible bulk of securities (i) registered in the name
of the Bank or its nominee,  or (ii) shown on the Bank's account on the books of
the Federal Reserve Bank.

                      3. The Bank (or its  agent)  shall  pay
for  securities  purchased  for the  account  of the  Fund  or  shall  pay  cash

to the  Account,  and (ii) the making of an entry on the records of the Bank (or
its agent) to reflect such payment and transfer for the account of the Fund. The
Bank (or its agent) shall transfer  securities sold or loaned for the account of
the Fund upon

                         (i)      Receipt   of  advice   from the Book-Entry
System that  payment  for  Securities  sold or payment of the initial  cash
collateral  against  the  delivery  of  securities  loaned  by the Fund has been
transferred to the Account, and

                         (ii)     The  making  of an entry on
the records of the Bank (or its agent) to reflect such  transfer and payment for
the account of the Fund.  Copies of all advices  from the  Book-Entry  System of
transfers of Securities  or the account of the Fund shall  identify the Fund, be
maintained  for the Fund by the Bank and  shall be  provided  to the Fund at its
request.  The Bank shall send the Fund a confirmation,  as defined by Rule 17f-4
under  the  Investment  Company  Act of 1940,  of any  transfers  to or from the
account of the Fund.

                      4. The Bank will  promptly  provide the
Fund  with  any  report  obtained  by the Bank or its  agent  on the  Book-Entry
System's  accounting  system,  internal  accounting  control and  procedures for
safeguarding  Securities  deposited  in the  Book-Entry  System.  The Bank  will
provide the Fund and cause any such agent to provide,  at such times as the Fund
may reasonably  require,  with reports by independent  public accountants on the
accounting system,  internal  accounting control and procedures for safeguarding
securities, including Securities deposited in the Book-Entry System, relating to
the services provided by the Bank or such agent under the Agreement.

                      5. Anything  to  the  contrary  in  the
Agreement notwithstanding,  the Bank shall be liable to the Fund for any loss or
damage to the Fund resulting from use of the Book-Entry  System by reason of any
negligence, willful misfeasance or bad faith of the Bank or any of its agents or
of any of its or their employees or from any negligent  disregard by the Bank or
any such agent of its duty to  enforce  effectively  such  rights as it may have
against the Book-Entry System; at the election of the Fund, it shall be entitled
to be subrogated for the Bank in any claim against the Book-Entry  System or any
other person which the Bank or its agent may have as a  consequence  of any such
loss or damage if and to the  extent  that the Fund has not been made  whole for
any loss or damage.
<PAGE>

                  (b) Use  of  a  Depository.   Provided  (i)  the
Bank  has  received  a  certified  copy  of a  resolution  of the  Fund's  Board
specifically  approving  deposits in DTC and PTC or other such Depository;  (ii)
the Bank  appoints  any such  depository  its  agent;  and  (iii)  for each year
following  such  Board  approval,  the  Board  has  reviewed  and  approved  the
arrangement  and  has  not  delivered  an  Officer's  Certificate  to  the  Bank
indicating that it has withdrawn its approval:

                      1. The  Bank  may use a  Depository  to
hold,  receive,  exchange,  release,  lend,  deliver and otherwise deal with the
securities owned by the Fund, including stock dividends,  rights and other items
of like  nature,  and to receive and remit to the Bank on behalf of the Fund all
income and other payments  thereon and to take all steps necessary and proper in
connection with the collection  thereof,  provided that such securities are held
in an  account  of the Bank (or its agent) in such  Depository  which  shall not
include  any  assets of the Bank (or such  agent)  other than  assets  held as a
fiduciary,  custodian, or otherwise for customers. The records of the Bank shall
identify those securities of the Trust held by the Depository.

                      2. Registration     of    the    Fund's
securities  may be made in the  name of any  nominee  or  nominees  used by such
Depository.

                      3. Payment  for  securities   purchased
and sold may be made through the clearing medium employed by such Depository for
transactions of participants  acting through it. Upon any purchase of securities
for the  account of the Fund,  payment  will be made only upon  delivery  of the
securities  to or for the  account  of the  Fund  and the  Fund  shall  pay cash
collateral  against  the  return  of  securities  loaned  by the Fund  only upon
delivery of the  securities to or for the account of the Fund; and upon any sale
of securities for the account of the Fund,  delivery of the  securities  will be
made only  against  payment  thereof  or, in the event  securities  are  loaned,
delivery of  securities  will be made only  against  receipt of the initial cash
collateral to or for the account of the Fund.

                      4. Anything  to  the  contrary  in  the
Agreement notwithstanding,  the Bank shall be liable to the Fund for any loss or
damage  to  the  Fund  resulting  from  use of a  Depository  by  reason  of any
negligence, willful misfeasance or bad faith of the Bank or any of its agents or
of any of its or their employees or from any negligent  disregard by the Bank or
any such agent of its duty to  enforce  effectively  such  rights as it may have
against a  Depository.  at the election of the Fund,  it shall be entitled to be
subrogated  for the Bank in any claim  against a Depository  or any other person
which the Bank or its agent may have as a consequence of any such loss or damage
if and to the  extent  that the Fund has not  been  made  whole  for any loss or
damage.  In this  connection,  with respect to the use of the  Depository by the
Bank, the Bank, without cost to the Fund, shall ensure that:

                         (i)      The Depository obtains replacement of any
certificated security deposited with it in the event such security is lost,
destroyed,  wrongfully  taken or otherwise  not  available to be returned to the
Bank upon its request;

                         (ii)     Any proxy materials received by Depository
with respect to securities of the Fund deposited  with such  Depository are
forwarded immediately to the Bank for prompt transmittal to the Fund;
<PAGE>

                         (iii)    Such Depository immediately forwards to the

account;

                         (iv)     Such Depository  prepares and delivers to the
Bank such records with respect to the performance of the Bank's obligations
and duties  hereunder as may be necessary for the Fund to comply with the record
keeping  requirements  of Section 31(a) of the Act and Rule 31a  thereunder  and
such other rules and regulations  relating to record keeping requirements of the
Fund as may be enacted from time to time; and

                         (v)      Such Depository delivers to the Bank and the
Fund all internal accounting control reports,  whether or not audited by an
independent  public  accountant,  as well as such other  reports as the Fund may
reasonably  request  in order  to  verify  the  Fund's  securities  held by such
Depository.

                  (c) Use of  Book-Entry  System for  Commercial Paper.

Agreement with the approval of the Board,  the "Fund's  damages" for the purpose
of the preceding  sentence  will be determined  based on the market value of the
property  which is the subject of the loss at the date of discovery of such loss
and without reference to any special conditions or circumstances

             The Bank will be under no duty or  obligation  to inquire into
and will not be liable for:

             (a)  The  validity of the issue of any  Portfolio securities
purchased by or for the Fund, the legality of the purchases  thereof or the
propriety of the price incurred therefor;

             (b)  The  legality  of any sale of any  portfolio securities by or
for the Fund or the propriety of the amount for which the same are sold;

             (c)  The  legality  of an  issue  or  sale of any shares of
beneficial  interest  of the Fund or the  sufficiency  of the  amount to be
received therefor:

             (d)  The legality of the repurchase of any shares of  beneficial
interest of the Fund or the propriety of the amount to be paid therefor;

             (e)  The legality of the declaration of any dividend by the Fund

in kind of such dividend; or

             (f)  Any property or moneys of the Fund already delivered or paid
by the Bank pursuant to the terms hereof.

              Moreover.  the Bank  will  not be  under  any duty or obligation
to ascertain  whether any Portfolio  securities at any time delivered to or
held by it for the  account of the Fund are such as may  properly be held by the
Fund under the provisions of its Declaration of Trust or By-Laws. any federal or
state statutes or any rule or regulation of any governmental agency.

Portfolio securities made hereunder, and for all necessary proper disbursements,
expenses  and charges  made or incurred by the Bank in the  performance  of this
Agreement (including any duties listed on any Schedule hereto, if any) including
any indemnities for any loss, liabilities or expense to the Bank as specifically
provided above. For the services  rendered by the Bank hereunder,  the Fund will
pay to the Bank  such  compensation  or fees at such  rate and at such  times as
shall be agreed upon in writing by the parties from time to time.  The Bank will
also be  entitled  to  reimbursement  by the Fund for all  preapproved  expenses
incurred in conjunction with termination of this Agreement by the Fund.
<PAGE>

             12.3 Advances by Bank.  The Bank may, in its sole  discretion,
advance  funds  on  behalf  of the Fund to make any  payment  permitted  by this
Agreement  upon receipt of any proper  authorization  required by this Agreement
for such payments by the Fund. Should such a payment or payments,  with advanced
funds, result in an overdraft (due to insufficiencies of the Fund's account with
the Bank,  or for any other  reason)  this  Agreement  deems any such or related
indebtedness,  a loan made by the Bank to the Fund  payable  on demand and being
interest at the rate set forth in writing by the Bank concurrently  herewith (as
amended  from time to time)  unless the Fund shall  provide the Bank with agreed
upon  compensating  balances.  The  Fund  agrees  that  the  Bank  shall  have a
continuing lien and security interest on the assets of the Fund to the extent of
any  overdraft,  provided  that in no event shall the amount of such lien exceed
the lesser of (i) the amount of such  overdraft  or (ii) 10% of the Fund's gross
assets on the date of such  overdraft,  and provided  further that to the extent
consistent with the foregoing, the Bank will comply with any Proper Instructions
indicating which Portfolio  securities and/or which account of the Fund shall be
subject to such lien. If such overdraft is not repaid within a reasonable period
of time,  the Bank shall have the right to exercise  any rights it may have as a
lien holder or secured party.

         13. Termination.

             13.1 This  Agreement  may be  terminated  at any time  without
penalty upon sixty days written notice delivered by either party to the other by
means of  registered  mail,  and upon the  expiration  of such  sixty  days this
Agreement will  terminate:  provided,  however,  that the effective date of such
termination  may be  postponed to a date not more than ninety days from the date
of delivery of such notice (i) by the Bank in order to prepare for the  transfer
by the Bank of all of the  assets  of the Fund held  hereunder.  and (ii) by the
Fund in order to give the Fund an opportunity to make suitable  arrangements for
a successor custodian. The Fund may immediately terminate this Agreement: (i) in
the event of the  appointment  of a conservator or receiver for the Bank or upon
the happening of a like event; (ii) if the Bank shall make a general  assignment
for the benefit of creditors; admit in writing its inability to pay its debts as
they  become  due;  file a petition  in  bankruptcy  or a petition  seeking  any
reorganization, arrangement, composition, readjustment, liquidation, dissolution
or  similar  relief  under any  present  or future  bankruptcy,  reorganization,
insolvency or similar statute,  law or regulation or seek the appointment of any
trustee,   receiver,   custodian  or  liquidator  of  the  Bank  or  of  all  or
substantially all of its properties;  (iii) if a proceeding is commenced against
the Bank  seeking  relief or an  appointment  of a type  described  in paragraph
13.1(ii)  above and such  proceeding is not  dismissed  within 30 days after the
commencement  thereof;  (iv) if the Bank's  insurance  is  materially  adversely
changed. At any time after the termination of this Agreement,  the Fund will, at
its request,  have access to the records of the Bank relating to the performance
of its duties as custodian.

             13.2 In the event of the  termination of this  Agreement,  the
Bank will immediately upon receipt or transmittal, as the case may be, of notice
of termination,  commence and prosecute diligently to completion the transfer of
all cash and the  delivery of all  Portfolio  securities  duly  endorsed and all
records maintained under Section 11 to the successor custodian when appointed by
the Fund.  The obligation of the Bank to deliver and transfer over the assets of
the Fund held by it directly to such  successor  custodian will commence as soon
as such successor is appointed and will continue  until  completed as aforesaid.
If the Fund does not select a successor  custodian  within ninety (90) days from
the date of  delivery  of notice of  termination  the Bank may,  subject  to the
provisions  of  subsection  13.3 of  this  Section  13,  deliver  the  Portfolio
securities  and cash of the Fund held by the Bank to a bank or trust  company of
its own  selection  which  meets the  requirements  of Section  17(f)(1)  of the
Investment Company Act of 1940 and has a reported capital, surplus and undivided
profits aggregating not less than $25,000,000, to be held as the property of the
Fund under terms similar to those on which they were held by the Bank, whereupon
such bank or trust  company so selected  by the Bank will  become the  successor
custodian of such assets of the Fund with the same effect as though  selected by
the Board.
<PAGE>

             13.3 Prior to the  expiration of ninety (90) days after notice
of  termination  has been given,  the Fund may furnish the Bank with an order of
the Fund advising that a successor custodian cannot be found willing and able to
act upon reasonable and customary terms and that there has been submitted to the
Board of the Fund the  question of whether the Fund will be  liquidated  or will
function  without a  custodian  for the assets of the Fund held by the Bank.  In
that event the Bank will deliver the Portfolio  securities  and cash of the Fund
held by it, subject as aforesaid,  in accordance  with one of such  alternatives
which may be approved by the  requisite  vote of the Board,  upon receipt by the
Bank of a copy of such vote  certified  by the  Fund's  Secretary  or  Assistant
Secretary.

         14. Notices.   Any   notice  or  other   instrument   in   writing
authorized  or required by this  Agreement  to be given to either  party  hereto
will be  sufficiently  given if  addressed to such party and mailed or delivered
to it at its office at the address set forth below; namely:

<PAGE>

             or at such  other  place as such  party  may from time to time
designate in writing.

         15. Amendments.  This  Agreement  may not be altered  or  amended,
except by an  instrument in writing,  executed by both parties,  and in the case
of the Fund,  any  alteration or amendment  which is material will be authorized
and approved by its Board.

         16. Parties. This Agreement will be binding upon and shall inure to the
benefit of the  parties  hereto and their  respective  successors  and  assigns;
provided,  however,  that  this  Agreement  will not be  assignable  by the Fund
without the prior  written  consent of the Bank or by the Bank without the prior
written consent of the Fund,  authorized and approved by its Board; and provided
further that termination  proceedings  pursuant to Section 13 hereof will not be
deemed to be an assignment within the meaning of this provision.

will be governed by the laws of the Commonwealth of Massachusetts.

         18. Interpretive  and Additional  Provisions.  In connection  with the
operation of this  Agreement,  the Bank and the Fund may from time to time agree
on such  provisions  interpretive  of or in addition to the  provisions  of this
Agreement as may in their joint opinion be consistent  with the general tenor of
this  Agreement.  Any such  interpretive  or additional  provisions  shall be in
writing  signed by both parties and shall be annexed hereto and shall be binding
upon the  parties  hereto  as if  incorporated  into  this  Agreement,  provided
however, no such interpretive or additional  provisions shall be deemed to be an
alteration or amendment of this Agreement.

         19. Delegation of Certain Duties Of Massachusetts  Financial  Services
Company  ("MFS").  The Bank, with the prior written consent of MFS, may delegate
to MFS the  performance of any or all of the duties it has agreed to perform for
the  Fund  in a  separate  written  agreement  relating  to (i)  accounting  for
investments  in  currency  and for  financial  instruments  (including,  without
limitation,  options contracts, futures contracts, options on futures contracts,
options on foreign currency and forward foreign currency exchange contracts) and
(ii) federal and state regulatory compliance.  The Bank shall compensate MFS for
the  performance of such duties at such fee or fees as MFS shall determine to be
equal to MFS' cost for  performing  such duties (the "MFS Fees")  Following  its
payment of MFS Fees to MFS,  the Bank shall  recover  the amount of the MFS Fees
from the Fund on such terms as the Bank and the Fund shall  agree.  MFS  assumes
responsibility  for all  duties  delegated  to it by the Bank  pursuant  to this
Section 19, and the Bank may rely on MFS for the accuracy and correctness of the
accounting information provided by MFS to the Bank pursuant to this Section 19.

                      Dividend Disbursing Agency Agreement

Dear Sirs:

         Each  of  the  above-listed  funds  (individually,  the  "Fund")  is an
open-end  registered  investment  company organized as a Massachusetts  business
trust.  Each Fund separately has selected you to act as its Dividend  Disbursing
Agent and you  hereby  agree to act as such  Agent and  perform  the  duties and
functions  thereof in the manner and on the  conditions  hereinafter  set forth.
Accordingly, each Fund individually hereby agrees with you as follows:

         1. Services to be Performed.  As Dividend  Disbursing  Agent ("Agent"),
you shall be responsible  for performing  dividend and  distribution  disbursing
agent  functions  with  regard  to the  Fund's  shares  of  beneficial  interest
("Shares"). The details of the operating standards and procedures to be followed
by you shall be  determined  from time to time by agreement  between you and the
Fund.

         2.  Standard  of Service.  As Agent for the Fund,  you agree to provide
service equal to at least that provided by you or others furnishing dividend and
distribution   disbursing  services  to  other  open-end  investment   companies
("Standard") at a fee, as may be agreed to from time to time,  comparable to the
fee paid you for your services  hereunder.  The Standard  shall include at least
the following:

               (a)  Prompt processing of all matters requiring action by you;

               (b)  Prompt clearance of any daily volume backlog;

               (c)  Providing innovative services and technological
improvements;

               (d)  Meeting the requirements of any governmental authority
having jurisdiction over you or the Fund; and

               (e)  Prompt reconciliation of all bank accounts under your
control belonging to the Fund.
<PAGE>

               If the Fund is reasonably  of the view that the service  provided
by you does not meet the Standard,  it shall give you written notice  specifying
the  particulars,  and you then  shall  have 120  days in which to  restore  the
service so that it meets the Standard, except that such period shall be 180 days
with respect to meeting that portion of the Standard described above in item (c)
of this paragraph 2. If at the end of such period the Fund remains reasonably of
the view that the service provided by you in the particulars specified, does not
meet the Standard,  then the Fund may, by appropriate action, elect to terminate
this  Agreement for cause upon 90 days notice to you. Upon  termination  hereof,
the Fund shall pay you such  compensation as may be due to you as of the date of
such termination,  and shall likewise reimburse you for any costs, expenses, and
disbursements reasonably incurred by you to such date in the performance of your
duties hereunder.

         3.  Rights in Data and  Confidentiality.  You agree  that all  records,
data, files, input materials,  reports, forms and other data received,  computed
or stored in the performance of this Agreement are the exclusive property of the
Fund and that all  such  records  and  other  data  shall be  furnished  without
additional  charge,  except for actual  processing costs, to the Fund in machine
readable as well as printed form  immediately upon termination of this Agreement
or at the Fund's request.  You shall safeguard and maintain the  confidentiality
of the Fund's data and information supplied to you by the Fund and you shall not
transfer or disclose the Fund's data to any third party without the Fund's prior
written  consent  unless  compelled  to do so by order of a court or  regulatory
authority.

         4. Fees. The fee, based upon check  clearance and  reconciliation  work
performed hereunder, shall not be in excess of such amount as shall be agreed in
writing between us. Such fee shall be payable in monthly installments.  Such fee
shall be subject to review at least  annually  and fixed by the  parties in good
faith negotiation on the basis of a statement of your expenses, which either you
or the Fund may require to be certified by a major accounting firm acceptable to
the parties.  The party  requesting such  certification  shall bear all expenses
thereof.  In addition to the  foregoing  fee, you will be reimbursed by the Fund
for  out-of-pocket  expenses  reasonably  incurred by you on behalf of the Fund,
including  but not limited to expenses for  stationery,  postage,  telephone and
telegraph line and toll charges and similar items.

         5. Record  Keeping.  You will maintain  records in a form acceptable to
the Fund and in compliance  with the rules and regulations of the Securities and
Exchange  Commission,  including,  but not  limited to,  records  required to be
maintained by Section 31(a) of the Investment  Company Act of 1940 and the rules
thereunder,  which at all  times  will be the  property  of the Fund and will be
available for inspection and use by the Fund or the Fund's transfer agent.
<PAGE>

         6. Duty of Care and Indemnification.  You will at all times act in good
faith in performing your duties hereunder. You will not be liable or responsible
for delays or errors by reason of circumstances  beyond your control,  including
acts of civil or military authority,  national emergencies,  labor difficulties,
fire,  mechanical breakdown beyond your control,  flood or catastrophe,  acts of
God, insurrection,  war, riots or failure beyond your control of transportation,
communication or power supply.  The Fund will indemnify you against and hold you
harmless  from any and all  losses,  claims,  damages,  liabilities  or expenses
(including  reasonable  counsel  fees and  expenses)  resulting  from any claim,
demand,  action or suit not  resulting  from your bad faith or  negligence,  and
arising  out of,  or in  connection  with,  your  duties  on  behalf of the Fund
hereunder.  In  addition,  the Fund  will  indemnify  you  against  and hold you
harmless  from any and all  losses,  claims,  damages,  liabilities  or expenses
(including  reasonable  counsel  fees and  expenses)  resulting  from any claim,
demand,  action  or suit as a  result  of your  acting  in  accordance  with any
instructions  reasonably  believed by you to have been given  executed or orally
communicated  by any person duly authorized by the Fund or as a result of acting
in  accordance  with written or oral advice  reasonable  believed by you to have
been given by counsel for the Fund, or as a result of acting in accordance  with
any  instrument  or share  certificate  reasonably  believed by you to have been
genuine  and  signed,  countersigned  or  executed  by  any  person  or  persons
authorized to sign,  countersign  or execute the same (unless  contributed to by
your gross negligence or bad faith).  In any case in which the Fund may be asked
to  indemnify  you or hold you  harmless,  the  Fund  shall  be  advised  of all
pertinent facts concerning the situation in question and you will use reasonable
care to identify and notify the Fund promptly  concerning  any  situation  which
presents or appears  likely to present a claim for  indemnification  against the
Fund.  The Fund shall have the option to defend you  against any claim which may
be the subject of this indemnification, and in the event that the Fund so elects
such defense shall be conducted by counsel  chosen by the Fund and  satisfactory
to you and it will so  notify  you,  and  thereupon  the Fund  shall  take  over
complete  defense of the claim and you shall  sustain no further  legal or other
expenses  in such  situation  for  which  you seek  indemnification  under  this
paragraph,  except the expense of any  additional  counsel  retained by you. You
will in no case  confess any claim or make any  compromise  in any case in which
the Fund will be asked to  indemnify  you except with the Fund's  prior  written
consent.  The  obligations  of the parties  hereto  under this  paragraph  shall
survive the termination of this Agreement.
<PAGE>

         7. Insurance.  You will notify the Fund should any of your
insurance coverage, as set forth on Exhibit A hereto, be changed for any
reason, such notification to include the date of change and reason or reasons
therefor.

         8. Notices. All notices or other  communications  hereunder shall be in
writing  and  shall be  deemed  sufficient  if  mailed  to  either  party at the
addresses set forth in this Agreement, or at such other addresses as the parties
hereto may designate by notice to each other.

         9.    Further Assurances.  Each party agrees to perform such further
acts and execute such further documents as are necessary to effectuate the
purposes hereof.

         10.   Use of a Sub-Dividend Disbursing Agent.  Notwithstanding any
other provision of this Agreement, it is expressly understood and agreed that
you are authorized in the performance of your duties hereunder to employ one
or more Sub-Dividend Disbursing Agents.

         11. Termination. Neither this Agreement nor any provision hereof may be
changed,  waived,  discharged or terminated orally, but only by an instrument in
writing, which, except in the case of termination,  shall be signed by the party
against which  enforcement of such change waiver or discharge is sought.  Except
as  otherwise  provided in paragraph 2 hereof,  this  Agreement  shall  continue
indefinitely  until  terminated by 90 days' written  notice given by the Fund to
you or by you to the Fund. Upon termination  hereof, the Fund shall pay you such
compensation as may be due to you as of the date of such termination,  and shall
likewise  reimburse you for any costs,  expenses,  and disbursements  reasonably
incurred by you to such date in the  performance of your duties  hereunder.  You
agree to  cooperate  with  the Fund and  provide  all  necessary  assistance  in
effectuating an orderly transition upon termination of this Agreement.

associated with  transferring  the same to such form), and will cooperate in the
transfer of such duties and responsibilities, including provision for assistance
from your cognizant  personnel in the establishment of books,  records and other

                               MFS SERIES TRUST I
                             MFS EQUITY INCOME FUND
                               DISTRIBUTION PLAN

DISTRIBUTION  PLAN with  respect  to the  shares of  beneficial  interest  to be
designated "Class A" of the MFS EQUITY INCOME FUND (the "Fund"), a series of MFS
Series Trust I (the "Trust"),  a business trust organized and existing under the
laws of The Commonwealth of Massachusetts, dated this 2nd day of January, 1996.

                                  WITNESSETH:

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

WHEREAS,  the Trust  intends to  distribute  the Shares of  Beneficial  Interest
(without par value) of the Fund designated Class A Shares (the "Shares") in part
in  accordance  with Rule 12b-1 under the Act,  ("Rule  12b-1"),  and desires to
adopt this Distribution Plan (the "Plan") as a plan of distribution  pursuant to
such Rule; and

WHEREAS, the Trust has entered into a distribution  agreement (the "Distribution
Agreement") in a form approved by the Board of Trustees of the Trust (the "Board
of Trustees") in the manner specified in Rule 12b-1, with MFS Fund Distributors,
Inc., a Delaware  corporation,  as distributor (the "Distributor"),  whereby the
Distributor  provides  facilities and personnel and renders services to the Fund
in connection with the offering and distribution of the Shares; and

WHEREAS,  the Trust  recognizes and agrees that the Distributor  will enter into
agreements  ("Dealer  Agreements")  with  various  securities  dealers and other
financial  intermediaries  ("Dealers") pursuant to which the Dealers will act as
dealers of the Shares in connection with the offering of Shares; and

WHEREAS, the Distribution  Agreement provides that a sales charge may be paid by
investors who purchase  Shares and that the Distributor and Dealers will receive
such sales charge as partial  compensation for their services in connection with
sale of Shares; and

WHEREAS, the Board of Trustees, in considering whether the Fund should adopt and
implement this Plan, has evaluated such information as it deemed necessary to an
informed determination as to whether this Plan should be adopted and implemented
and has  considered  such pertinent  factors as it deemed  necessary to form the
basis  for a  decision  to use  assets  of the Fund for such  purposes,  and has
determined  that  there  is  a  reasonable  likelihood  that  the  adoption  and
implementation of this Plan will benefit the Fund and its Class A shareholders;
<PAGE>

NOW, THEREFORE,  the Board of Trustees hereby adopts this Plan for the Fund as a
plan of distribution  relating to the Shares in accordance with Rule 12b-1 under
the Act, on the following terms and conditions:

         1. As specified in the Distribution  Agreement,  the Distributor  shall
provide  facilities,  personnel  and a program  with respect to the offering and
sale of Shares. Among other things, the Distributor shall be responsible for any
ongoing maintenance  commissions to Dealers (excluding service fees described in
paragraph 4), all expenses of printing (excluding  typesetting) and distributing
prospectuses  to  prospective  shareholders  and  providing  such other  related
services as are reasonably necessary in connection therewith.

         2.  The  Distributor  shall  bear  all  distribution-related   expenses
described  in Section 1,  including  without  limitation,  the  compensation  of
personnel  necessary  to provide such  services and all costs of travel,  office
expenses  (including  rent and  overhead),  equipment,  printing,  delivery  and
mailing costs.

         3. As partial  consideration for the services performed as specified in
the  Distribution  Agreement  and expenses  incurred in the  performance  of its
obligations under the Distribution Agreement, the Fund shall pay the Distributor
a distribution  fee  periodically at a rate not to exceed 0.25% per annum of the
average daily net assets of the Fund  attributable to the Shares.  Such payments
shall  commence  following  shareholder  approval  of the  Plan  but  only  upon
notification by the Distributor to the Fund of the commencement of the Plan (the
"Commencement  Date"). All or a portion of the distribution fee paid by the Fund
to the Distributor may be paid by the Distributor to Dealers in consideration of
the Dealer's  services as a dealer of the Shares.  The Distributor may from time
to time establish minimum amount requirements and additional or different dealer
qualification  standards  or other  criteria to be met by dealers for payment of
any fee under this paragraph 3. It is understood that the  Distributor  may, but
is not  required  to, pay  reduced  fees or no fees under  this  paragraph  3 to
Dealers with respect to assets  represented  by Shares that have  converted from
shares of beneficial interest of the Fund designated "Class B."

         4. As partial  consideration  for the personal  services and/or account
maintenance  services  performed  by  each  Dealer  in  the  performance  of its
obligations  under  its  Dealer  Agreement,  the  Fund  shall  on or  after  the
Commencement  Date pay each Dealer a service fee  periodically  at a rate not to
exceed  0.25% per annum of the  portion of the  average  daily net assets of the
Fund that is  represented  by Shares that are owned by  investors  for whom such
Dealer is the holder or dealer of record.  The Distributor may from time to time
reduce the amount of the  service  fee paid to a Dealer  with  respect to Shares
sold prior to a certain date.

         5. In addition to fees payable pursuant to Sections 3 and 4 hereof, the
expenses  permitted to be paid by the Fund pursuant to this Plan on or after the
Commencement Date shall include other distribution related expenses. These other
distribution  related  expenses  may  include,  but are not limited to, a dealer
commission and a payment to wholesalers employed by the Distributor on net asset
value purchases at or above a certain dollar level.
<PAGE>

         The  aggregate  amount of fees and expenses paid pursuant to Sections 3
and 4 hereof and this  Section 5 shall not exceed 0.50% per annum of the average
daily net assets of the Fund  attributable to the Shares.  No fees shall be paid
pursuant to Section 4 hereof or this Section 5 to any  insurance  company  which
has  entered  into an  agreement  with the  Trust on  behalf of the Fund and the
Distributor that permits such insurance company to purchase Shares from the Fund
at their  net  asset  value in  connection  with  annuity  agreements  issued in
connection with the insurance  company's separate accounts.  That portion of the
Fund's average daily net assets on which fees payable under Section 4 hereof and
this  Section  5 are  calculated  may  be  subject  to  certain  minimum  amount
requirements  as may be  determined,  and  additional  or  different  dealer  or
wholesaler qualification standards that may be established, from time to time by
the Distributor.  The Distributor  shall be entitled to be paid any fees payable
under  Section 4 hereof or this  Section 5 with respect to accounts for which no
Dealer of record exists or qualification  standards have not been met as partial
consideration for personal services and/or account maintenance services provided
by the  Distributor  to the Shares.  The fees and expenses  payable  pursuant to
Section  4 and this  Section  5 may from time to time be paid by the Fund to the
Distributor  and the  Distributor  will then pay these expenses on behalf of the
Fund.

         6.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         7. This Plan shall become  effective  upon (a) approval by a vote of at
least a "majority of the outstanding  voting  securities" of the Shares, and (b)
approval  by a vote of the  Board  of  Trustees  and vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest  in the  operation  of the  Plan  or in any of the
agreements related to the Plan (the "Qualified Trustees"), such votes to be cast
in person at a meeting called for the purpose of voting on this Plan.

         8. This Plan shall continue in effect indefinitely;  provided, however,
that such  continuance  is subject to annual  approval by a vote of the Board of
Trustees  and a majority  of the  Qualified  Trustees,  such votes to be cast in
person at a meeting  called  for the  purpose of voting on  continuance  of this
Plan. If such annual approval is not obtained,  this Plan shall expire 12 months
after the effective date of the last approval.

         9.  This  Plan may be  amended  at any time by the  Board of  Trustees;
provided  that (a) any amendment to increase  materially  the amount to be spent
for the services  described  herein shall be effective  only upon  approval by a
vote of a "majority of the outstanding  voting securities" of the Shares and (b)
any material  amendment of this Plan shall be effective  only upon approval by a
vote of the Board of Trustees  and a majority of the  Qualified  Trustees,  such
votes to be cast in person at a meeting called for the purpose of voting on such
amendment.  This Plan may be terminated at any time by vote of a majority of the
Qualified  Trustees  or by a  vote  of a  "majority  of the  outstanding  voting
securities" of the Shares.
<PAGE>

         10. The Distributor shall provide the Board of Trustees,  and the Board
of Trustees shall review,  at least  quarterly,  a written report of the amounts
expended under the Plan and the purposes for which such expenditures were made.

         11. While this Plan is in effect, the selection and nomination
of Qualified Trustees shall be committed to the discretion of the Trustees who
are not "interested persons" of the Trust.

         12. For the purposes of this Plan,  the terms  "interested  person" and
"majority of the outstanding  voting securities" are used as defined in the Act.
In  addition,  for  purposes  of  determining  the fees  payable to Dealers  and
wholesalers, the value of the Share's net assets shall be computed in the manner
specified in the Fund's then current prospectus for computation of the net asset
value of the Shares.

         13. The Trust shall  preserve  copies of this Plan,  and each agreement
related  hereto and each report  referred to in Section 10 hereof  (collectively
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  Record  shall be kept in an easily
accessible place for the first two years of said record keeping.

         14. This Plan shall be construed in accordance with the laws of
The Commonwealth of Massachusetts and the applicable provisions of the 1940
Act.

         15. If any  provision  of this Plan shall be held or made  invalid by a
court decision,  statute, rule or otherwise, the remainder of the Plan shall not
be affected thereby.

         5.  In addition to fees payable pursuant to Sections 3 and 4 hereof,

These other distribution related expenses may include, but are not limited to, a

<PAGE>

         The  aggregate  amount of fees and expenses paid pursuant to Sections 3
and 4 hereof and this  Section 5 shall not exceed 0.50% per annum of the average

                               DISTRIBUTION PLAN

DISTRIBUTION  PLAN with  respect  to the  shares of  beneficial  interest  to be
designated  "Class A" of the MFS CORE GROWTH FUND (the "Fund"),  a series of MFS
Series Trust I (the "Trust"),  a business trust organized and existing under the
laws of The Commonwealth of Massachusetts, dated this 2nd day of January, 1996.

                                  WITNESSETH:

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

WHEREAS,  the Trust  intends to  distribute  the Shares of  Beneficial  Interest
(without par value) of the Fund designated Class A Shares (the "Shares") in part
in  accordance  with Rule 12b-1 under the Act,  ("Rule  12b-1"),  and desires to
adopt this Distribution Plan (the "Plan") as a plan of distribution  pursuant to
such Rule; and

WHEREAS, the Trust has entered into a distribution  agreement (the "Distribution
Agreement") in a form approved by the Board of Trustees of the Trust (the "Board
of Trustees") in the manner specified in Rule 12b-1, with MFS Fund Distributors,
Inc., a Delaware  corporation,  as distributor (the "Distributor"),  whereby the
Distributor  provides  facilities and personnel and renders services to the Fund
in connection with the offering and distribution of the Shares; and

WHEREAS,  the Trust  recognizes and agrees that the Distributor  will enter into
agreements  ("Dealer  Agreements")  with  various  securities  dealers and other
financial  intermediaries  ("Dealers") pursuant to which the Dealers will act as
dealers of the Shares in connection with the offering of Shares; and

WHEREAS, the Distribution  Agreement provides that a sales charge may be paid by
investors who purchase  Shares and that the Distributor and Dealers will receive
such sales charge as partial  compensation for their services in connection with
sale of Shares; and

WHEREAS, the Board of Trustees, in considering whether the Fund should adopt and
implement this Plan, has evaluated such information as it deemed necessary to an
informed determination as to whether this Plan should be adopted and implemented
and has  considered  such pertinent  factors as it deemed  necessary to form the
basis  for a  decision  to use  assets  of the Fund for such  purposes,  and has
determined  that  there  is  a  reasonable  likelihood  that  the  adoption  and
implementation of this Plan will benefit the Fund and its Class A shareholders;

NOW, THEREFORE,  the Board of Trustees hereby adopts this Plan for the Fund as a
plan of distribution  relating to the Shares in accordance with Rule 12b-1 under
the Act, on the following terms and conditions:
<PAGE>

         1. As specified in the Distribution  Agreement,  the Distributor  shall
provide  facilities,  personnel  and a program  with respect to the offering and
sale of Shares. Among other things, the Distributor shall be responsible for any
ongoing maintenance  commissions to Dealers (excluding service fees described in
paragraph 4), all expenses of printing (excluding  typesetting) and distributing
prospectuses  to  prospective  shareholders  and  providing  such other  related
services as are reasonably necessary in connection therewith.

         2.  The  Distributor  shall  bear  all  distribution-related   expenses
described  in Section 1,  including  without  limitation,  the  compensation  of
personnel  necessary  to provide such  services and all costs of travel,  office
expenses  (including  rent and  overhead),  equipment,  printing,  delivery  and
mailing costs.

         3.  As partial consideration for the services performed as specified in
the  Distribution  Agreement  and expenses  incurred in the  performance  of its
obligations under the Distribution Agreement, the Fund shall pay the Distributor
a distribution  fee  periodically at a rate not to exceed 0.25% per annum of the
average daily net assets of the Fund  attributable to the Shares.  Such payments
shall  commence  following  shareholder  approval  of the  Plan  but  only  upon
notification by the Distributor to the Fund of the commencement of the Plan (the
"Commencement  Date"). All or a portion of the distribution fee paid by the Fund
to the Distributor may be paid by the Distributor to Dealers in consideration of
the Dealer's  services as a dealer of the Shares.  The Distributor may from time
to time establish minimum amount requirements and additional or different dealer
qualification  standards  or other  criteria to be met by dealers for payment of
any fee under this paragraph 3. It is understood that the  Distributor  may, but
is not  required  to, pay  reduced  fees or no fees under  this  paragraph  3 to
Dealers with respect to assets  represented  by Shares that have  converted from
shares of beneficial interest of the Fund designated "Class B."

         4.  As partial consideration  for the personal  services and/or account
maintenance  services  performed  by  each  Dealer  in  the  performance  of its
obligations  under  its  Dealer  Agreement,  the  Fund  shall  on or  after  the
Commencement  Date pay each Dealer a service fee  periodically  at a rate not to
exceed  0.25% per annum of the  portion of the  average  daily net assets of the
Fund that is  represented  by Shares that are owned by  investors  for whom such
Dealer is the holder or dealer of record.  The Distributor may from time to time
reduce the amount of the  service  fee paid to a Dealer  with  respect to Shares
sold prior to a certain date.

         5.  In addition to fees payable pursuant to Sections 3 and 4 hereof,
the expenses  permitted to be paid by the Fund  pursuant to this Plan on or
after the Commencement Date shall include other  distribution  related expenses.
These other distribution related expenses may include, but are not limited to, a
dealer  commission and a payment to wholesalers  employed by the  Distributor on
net asset value purchases at or above a certain dollar level.
<PAGE>

         The  aggregate  amount of fees and expenses paid pursuant to Sections 3
and 4 hereof and this  Section 5 shall not exceed 0.50% per annum of the average
daily net assets of the Fund  attributable to the Shares.  No fees shall be paid
pursuant to Section 4 hereof or this Section 5 to any  insurance  company  which
has  entered  into an  agreement  with the  Trust on  behalf of the Fund and the
Distributor that permits such insurance company to purchase Shares from the Fund
at their  net  asset  value in  connection  with  annuity  agreements  issued in
connection with the insurance  company's separate accounts.  That portion of the
Fund's average daily net assets on which fees payable under Section 4 hereof and
this  Section  5 are  calculated  may  be  subject  to  certain  minimum  amount
requirements  as may be  determined,  and  additional  or  different  dealer  or
wholesaler qualification standards that may be established, from time to time by
the Distributor.  The Distributor  shall be entitled to be paid any fees payable
under  Section 4 hereof or this  Section 5 with respect to accounts for which no
Dealer of record exists or qualification  standards have not been met as partial
consideration for personal services and/or account maintenance services provided
by the  Distributor  to the Shares.  The fees and expenses  payable  pursuant to
Section  4 and this  Section  5 may from time to time be paid by the Fund to the
Distributor  and the  Distributor  will then pay these expenses on behalf of the
Fund.

         6.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         7.  This Plan shall become effective upon (a) approval by a vote of at
least a "majority of the outstanding  voting  securities" of the Shares, and (b)
approval  by a vote of the  Board  of  Trustees  and vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest  in the  operation  of the  Plan  or in any of the
agreements related to the Plan (the "Qualified Trustees"), such votes to be cast
in person at a meeting called for the purpose of voting on this Plan.

         8.  This Plan shall continue in effect indefinitely; provided, however,
that such  continuance  is subject to annual  approval by a vote of the Board of
Trustees  and a majority  of the  Qualified  Trustees,  such votes to be cast in
person at a meeting  called  for the  purpose of voting on  continuance  of this
Plan. If such annual approval is not obtained,  this Plan shall expire 12 months
after the effective date of the last approval.

         9.  This  Plan may be  amended  at any time by the  Board of  Trustees;
provided  that (a) any amendment to increase  materially  the amount to be spent
for the services  described  herein shall be effective  only upon  approval by a
vote of a "majority of the outstanding  voting securities" of the Shares and (b)
any material  amendment of this Plan shall be effective  only upon approval by a
vote of the Board of Trustees  and a majority of the  Qualified  Trustees,  such
votes to be cast in person at a meeting called for the purpose of voting on such
amendment.  This Plan may be terminated at any time by vote of a majority of the
Qualified  Trustees  or by a  vote  of a  "majority  of the  outstanding  voting
securities" of the Shares.

         10. The Distributor shall provide the Board of Trustees,  and the Board
of Trustees shall review,  at least  quarterly,  a written report of the amounts
expended under the Plan and the purposes for which such expenditures were made.
<PAGE>

         11. While this Plan is in effect, the selection and nomination
of Qualified Trustees shall be committed to the discretion of the Trustees who
are not "interested persons" of the Trust.

         12. For the purposes of this Plan,  the terms  "interested  person" and
"majority of the outstanding  voting securities" are used as defined in the Act.
In  addition,  for  purposes  of  determining  the fees  payable to Dealers  and
wholesalers, the value of the Share's net assets shall be computed in the manner
specified in the Fund's then current prospectus for computation of the net asset
value of the Shares.

         13. The Trust shall  preserve  copies of this Plan,  and each agreement
related  hereto and each report  referred to in Section 10 hereof  (collectively
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  Record  shall be kept in an easily
accessible place for the first two years of said record keeping.

         14. This Plan shall be construed in accordance with the laws of
The Commonwealth of Massachusetts and the applicable provisions of the 1940
Act.

         15. If any  provision  of this Plan shall be held or made  invalid by a
court decision,  statute, rule or otherwise, the remainder of the Plan shall not
be affected thereby.

that such  continuance  is subject to annual  approval by a vote of the Board of
Trustees  and a majority  of the  Qualified  Trustees,  such votes to be cast in
person at a meeting  called  for the  purpose of voting on  continuance  of this
Plan. If such annual approval is not obtained,  this Plan shall expire 12 months

value of the Shares.

                                  WITNESSETH:

WHEREAS,  the Trust is engaged in business as an open-end management  investment
company and is registered  under the Investment  Company Act of 1940, as amended
(collectively with the rules and regulations promulgated  thereunder,  the "1940
Act"); and

WHEREAS,  the Trust  intends to  distribute  the shares of  beneficial  interest
(without  par value) of the Fund  designated  Class B Shares (the  "Shares")  in
accordance  with Rule 12b-1  under the 1940 Act ("Rule  12b-1"),  and desires to

such Rule; and

WHEREAS,  the  Trust  desires  for  MFS  Fund  Distributors,  Inc.,  a  Delaware
corporation,  to  provide  certain  distribution  services  for  the  Fund  (the
"Distributor"); and

WHEREAS, the Trust has entered into a distribution  agreement (the "Distribution
Agreement")  (in a form  approved  by the  Board of  Trustees  of the Trust in a
manner  specified  in  such  Rule  12b-1)  with  the  Distributor,  whereby  the
Distributor  will provide  facilities  and personnel and render  services to the
Fund in connection with the offering and distribution of the Shares; and

WHEREAS, the Trust recognizes and agrees that (a) the Distributor may retain the
services of firms or individuals to act as dealers (the "Dealers") of the Shares
in  connection  with the offering of Shares,  and (b) the  Distributor  may make
payments for such services to the Dealers out of the fee paid to the Distributor

with the repurchase of Shares,  its profits or any other source available to it;
and

WHEREAS, the Trust recognizes and agrees that the Distributor may impose certain
deferred sales charges in connection  with the repurchase of Shares by the Fund,
and the  Distributor  may retain (or receive from the Fund,  as the case may be)
all such deferred sales charges; and

WHEREAS,  the Board of Trustees of the Trust,  in  considering  whether the Fund
should adopt and implement  this Plan,  has  evaluated  such  information  as it
deemed necessary to an informed  determination as to whether this Plan should be
adopted and implemented  and has considered such pertinent  factors as it deemed
necessary  to form the basis for a  decision  to use assets of the Fund for such
purposes,  and has  determined  that there is a reasonable  likelihood  that the
adoption and  implementation  of this Plan will benefit the Fund and its Class B
shareholders;
<PAGE>

NOW,  THEREFORE,  the Board of Trustees of the Trust hereby adopts this Plan for
the Fund as a plan for  distribution  relating to the Shares in accordance  with
Rule 12b-1, on the following terms and conditions:

1. As specified in the  Distribution  Agreement,  the Distributor  shall provide
facilities,  personnel  and a program  with  respect to the offering and sale of
Shares. Among other things, the Distributor shall be responsible for commissions
payable to  Dealers,  all  expenses  of  printing  (excluding  typesetting)  and
distributing  prospectuses to prospective  shareholders and providing such other
related services as are reasonably necessary in connection therewith.

2. The Distributor  shall bear all  distribution-related  expenses to the extent
specified in the Distribution  Agreement in providing the services  described in
paragraph  1,  including  without  limitation,  the  compensation  of  personnel
necessary to provide  such  services  and all costs of travel,  office  expenses
(including rent and overhead), equipment, Printing delivery and Mailing costs.

3. It is understood  that the  Distributor  may impose  certain  deferred  sales
charges  in  connection  with  the  repurchase  of  Shares  by the  Fund and the
Distributor  may retain (or receive from the Fund,  as the case may be) all such
deferred sales charges.  As additional  consideration for all services performed
and  expenses   incurred  in  the  performance  of  its  obligations  under  the
Distribution  Agreement,  the Fund shall pay the Distributor a distribution  fee
periodically at a rate of 0.75% per annum of the Fund's average daily net assets
attributable to the shares.

4. As partial consideration for the personal services and/or account maintenance
services  performed by each Dealer in the performance of its  obligations  under
its dealer  agreement  with the  Distributor,  the Fund shall pay each  Dealer a
service fee  periodically at a rate not to exceed 0.25% per annum of the portion
of the average daily net assets of the Fund that is  represented  by Shares that
are owned by  investors  for whom such Dealer is the holder or dealer of record.
That  portion of the Fund's  average  daily net assets on which the fees payable
under this paragraph 4 hereof are  calculated may be subject to certain  minimum
amount  requirements  as may be determined,  and additional or different  dealer
qualification  standards  that may be  established  from  time to  time,  by the
Distributor. The Distributor shall be entitled to be paid any fees payable under
this  paragraph  4 hereof  with  respect to Shares for which no Dealer of record
exists or qualification standards have not been met as partial consideration for
personal   services  and/or  account   maintenance   services  provided  by  the
Distributor to the Shares.  The service fee payable pursuant to this paragraph 4
may from time to time be paid by the Fund to the Distributor and the Distributor
will then pay these fees on behalf of the Fund.

5. The Fund understands that agreements  between the Distributor and the Dealers
may provide for payment of commissions  to Dealers in connection  with the sales
of Shares and may provide for a portion (which may be all or substantially  all)
of the  fees  payable  by the Fund to the  Distributor  under  the  Distribution
Agreement to be paid by the Distributor to the Dealers in  consideration  of the
Dealer's services as a dealer of the Shares. Except as described in paragraph 4,
nothing  in this  Plan  shall be  construed  as  requiring  the Fund to make any
payment to any  Dealer or to have any  obligations  to any Dealer in  connection
with  services  as a dealer  of the  Shares.  The  Distributor  shall  agree and
undertake that any agreement entered into between the Distributor and any Dealer
shall  provide  that,  except as provided in paragraph 4, such Dealer shall look
solely to the Distributor for compensation for its services  thereunder and that
in no event shall such Dealer seek any payment from the Fund.
<PAGE>

6. The Fund shall pay all fees and expenses of any  independent  auditor,  legal
counsel,   investment  adviser,   administrator,   transfer  agent,   custodian,
shareholder servicing agent, registrar or dividend disbursing agent of the Fund;
expenses  of  distributing  and  redeeming  Shares  and  servicing   shareholder
accounts; expenses of preparing, printing and mailing prospectuses,  shareholder
reports,  notices,  proxy  statements and reports to  governmental  officers and
commissions and to shareholders of the Fund,  except that the Distributor  shall
be responsible for the distribution-related expenses as provided in paragraphs 1
and 2 hereof.

7.  Nothing  herein  contained  shall be deemed to require the Trust to take any
action  contrary  to its  Declaration  of Trust  or  By-Laws  or any  applicable
statutory  or  regulatory  requirement  to which it is subject or by which it is
bound, or to relieve or deprive the Board of Trustees of the  responsibility for
and control of the conduct of the affairs of the Fund.

8. This Plan shall  become  effective  upon (a) approval by a vote of at least a
"majority of the outstanding  voting securities" of the Shares, and (b) approval
by a vote of the Board of Trustees  and a vote of a majority of the Trustees who
are not  "interested  persons"  of the Trust and who have no direct or  indirect
financial  interest in the operation of the Plan or in any agreement  related to
the Plan  (the  "Qualified  Trustees"),  such  votes to be cast in  person  at a
meeting called for the purpose of voting on this Plan.

9.  This  Plan  shall  continue  in  effect  indefinitely;  provided  that  such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained,  this Plan shall expire 12 months after
the effective date of the last approval.

10. This Plan may be amended at any time by the Board of Trustees; provided that
this Plan may not be  amended to  increase  materially  the amount of  permitted
expenses  hereunder  without  the  approval  of  holders of a  "majority  of the
outstanding  voting  securities" of the Shares and may not be materially amended
in any case without a vote of a majority of both the Trustees and the  Qualified
Trustees. This Plan may be terminated at any time by a vote of a majority of the
Qualified Trustees or by a vote of the holders of a "majority of the outstanding
voting securities" of the Shares.

11. The Fund and the  Distributor  shall provide the Board of Trustees,  and the
Board of Trustees  shall review,  at least  quarterly,  a written  report of the
amounts  expended  under this Plan and the purposes for which such  expenditures
were made.

12.      While this Plan is in effect, the selection and nomination of

are not "interested persons" of the Trust.

13. For the purposes of this Plan, the terms "interested persons",  "majority of
the outstanding voting securities" and "specifically approved at least annually"

the fees  payable  to the  Distributor  hereunder,  the value of the  Fund's net
assets  shall be computed  in the manner  specified  in the Fund's then  current
prospectus and statement of additional  information  for  computation of the net
asset value of the Shares of the Fund.

14. The Trust shall preserve  copies of this Plan,  and each  agreement  related
hereto and each report  referred to in  paragraph 11 hereof  (collectively,  the
"Records")  for a period of six years from the end of the  fiscal  year in which
such Record was made and each such record shall be kept in an easily  accessible
place for the first two years of said record-keeping.

15. This Plan shall be construed in accordance with the laws of The
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

court decision, statute, rule or otherwise, the remainder of the Plan shall

the Fund as a plan for  distribution  relating to the Shares in accordance  with
Rule 12b-1, on the following terms and conditions:

1. As specified in the  Distribution  Agreement,  the Distributor  shall provide
facilities,  personnel  and a program  with  respect to the offering and sale of
Shares. Among other things, the Distributor shall be responsible for commissions
payable to  Dealers,  all  expenses  of  printing  (excluding  typesetting)  and
distributing  prospectuses to prospective  shareholders and providing such other
related services as are reasonably necessary in connection therewith.

2. The Distributor  shall bear all  distribution-related  expenses to the extent
specified in the Distribution  Agreement in providing the services  described in
paragraph  1,  including  without  limitation,  the  compensation  of  personnel
necessary to provide  such  services  and all costs of travel,  office  expenses
(including rent and overhead), equipment, Printing delivery and Mailing costs.

3. It is understood  that the  Distributor  may impose  certain  deferred  sales
charges  in  connection  with  the  repurchase  of  Shares  by the  Fund and the
Distributor  may retain (or receive from the Fund,  as the case may be) all such
deferred sales charges.  As additional  consideration for all services performed
and  expenses   incurred  in  the  performance  of  its  obligations  under  the
Distribution  Agreement,  the Fund shall pay the Distributor a distribution  fee
periodically at a rate of 0.75% per annum of the Fund's average daily net assets
attributable to the shares.

4. As partial consideration for the personal services and/or account maintenance
services  performed by each Dealer in the performance of its  obligations  under
its dealer  agreement  with the  Distributor,  the Fund shall pay each  Dealer a
service fee  periodically at a rate not to exceed 0.25% per annum of the portion
of the average daily net assets of the Fund that is  represented  by Shares that
are owned by  investors  for whom such Dealer is the holder or dealer of record.
That  portion of the Fund's  average  daily net assets on which the fees payable
under this paragraph 4 hereof are  calculated may be subject to certain  minimum
amount  requirements  as may be determined,  and additional or different  dealer
qualification  standards  that may be  established  from  time to  time,  by the
Distributor. The Distributor shall be entitled to be paid any fees payable under
this  paragraph  4 hereof  with  respect to Shares for which no Dealer of record
exists or qualification standards have not been met as partial consideration for
personal   services  and/or  account   maintenance   services  provided  by  the
Distributor to the Shares.  The service fee payable pursuant to this paragraph 4
may from time to time be paid by the Fund to the Distributor and the Distributor
will then pay these fees on behalf of the Fund.

5. The Fund understands that agreements  between the Distributor and the Dealers
may provide for payment of commissions  to Dealers in connection  with the sales
of Shares and may provide for a portion (which may be all or substantially  all)
of the  fees  payable  by the Fund to the  Distributor  under  the  Distribution
Agreement to be paid by the Distributor to the Dealers in  consideration  of the
Dealer's services as a dealer of the Shares. Except as described in paragraph 4,
nothing  in this  Plan  shall be  construed  as  requiring  the Fund to make any
payment to any  Dealer or to have any  obligations  to any Dealer in  connection
with  services  as a dealer  of the  Shares.  The  Distributor  shall  agree and
undertake that any agreement entered into between the Distributor and any Dealer
shall  provide  that,  except as provided in paragraph 4, such Dealer shall look
solely to the Distributor for compensation for its services  thereunder and that
in no event shall such Dealer seek any payment from the Fund.

6. The Fund shall pay all fees and expenses of any  independent  auditor,  legal
counsel,   investment  adviser,   administrator,   transfer  agent,   custodian,
shareholder servicing agent, registrar or dividend disbursing agent of the Fund;
expenses  of  distributing  and  redeeming  Shares  and  servicing   shareholder
accounts; expenses of preparing, printing and mailing prospectuses,  shareholder
reports,  notices,  proxy  statements and reports to  governmental  officers and
commissions and to shareholders of the Fund,  except that the Distributor  shall
be responsible for the distribution-related expenses as provided in paragraphs 1
and 2 hereof.

7.  Nothing  herein  contained  shall be deemed to require the Trust to take any
action  contrary  to its  Declaration  of Trust  or  By-Laws  or any  applicable
statutory  or  regulatory  requirement  to which it is subject or by which it is
bound, or to relieve or deprive the Board of Trustees of the  responsibility for
and control of the conduct of the affairs of the Fund.

8. This Plan shall  become  effective  upon (a) approval by a vote of at least a
"majority of the outstanding  voting securities" of the Shares, and (b) approval
by a vote of the Board of Trustees  and a vote of a majority of the Trustees who
are not  "interested  persons"  of the Trust and who have no direct or  indirect
financial  interest in the operation of the Plan or in any agreement  related to
the Plan  (the  "Qualified  Trustees"),  such  votes to be cast in  person  at a
meeting called for the purpose of voting on this Plan.

9.  This  Plan  shall  continue  in  effect  indefinitely;  provided  that  such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained,  this Plan shall expire 12 months after
the effective date of the last approval.

10. This Plan may be amended at any time by the Board of Trustees; provided that
this Plan may not be  amended to  increase  materially  the amount of  permitted
expenses  hereunder  without  the  approval  of  holders of a  "majority  of the
outstanding  voting  securities" of the Shares and may not be materially amended
in any case without a vote of a majority of both the Trustees and the  Qualified
Trustees. This Plan may be terminated at any time by a vote of a majority of the
Qualified Trustees or by a vote of the holders of a "majority of the outstanding
voting securities" of the Shares.

11. The Fund and the  Distributor  shall provide the Board of Trustees,  and the
Board of Trustees  shall review,  at least  quarterly,  a written  report of the
amounts  expended  under this Plan and the purposes for which such  expenditures
were made.

12. While this Plan is in effect, the selection and nomination of
Qualified Trustees shall be committed to the discretion of the Trustees who
are not "interested persons" of the Trust.
<PAGE>

13. For the purposes of this Plan, the terms "interested persons",  "majority of
the outstanding voting securities" and "specifically approved at least annually"
are used as defined in the 1940 Act. In addition,  for  purposes of  determining
the fees  payable  to the  Distributor  hereunder,  the value of the  Fund's net
assets  shall be computed  in the manner  specified  in the Fund's then  current
prospectus and statement of additional  information  for  computation of the net
asset value of the Shares of the Fund.

14. The Trust shall preserve  copies of this Plan,  and each  agreement  related
hereto and each report  referred to in  paragraph 11 hereof  (collectively,  the
"Records")  for a period of six years from the end of the  fiscal  year in which
such Record was made and each such record shall be kept in an easily  accessible
place for the first two years of said record-keeping.

15. This Plan shall be construed in accordance with the laws of The
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act.

16. If any  provision  of this  Plan  shall be held or made  invalid  by a court
decision,  statute,  rule or  otherwise,  the remainder of the Plan shall not be
affected thereby.

                                  WITNESSETH:

         WHEREAS,  the Trust is engaged in business  as an  open-end  management
investment  company and is registered under the Investment  Company Act of 1940,
as amended (collectively with the rules and regulations  promulgated thereunder,
the "1940 Act"); and

         WHEREAS,  the Trust  intends to  distribute  the  shares of  beneficial
interest  (without  par  value)  of the  Fund  designated  Class C  Shares  (the
"Shares") in accordance with Rule 12b-1 under the 1940 Act ("Rule  12b-1"),  and
desires to adopt this  Distribution  Plan (the "Plan") as a plan of distribution
pursuant to such Rule; and

         WHEREAS, the Trust desires for MFS Fund Distributors,  Inc., a Delaware
corporation,  to  provide  certain  distribution  services  for  the  Fund  (the
"Distributor"); and

         WHEREAS,  the Trust has  entered  into a  distribution  agreement  (the
"Distribution  Agreement")  (in a form  approved by the Board of Trustees of the
Trust in a manner  specified  in Rule 12b-1) with the  Distributor,  whereby the
Distributor  will provide  facilities  and personnel and render  services to the
Fund in connection with the offering and distribution of the Shares; and

         WHEREAS,  the Trust  recognizes and agrees that (a) the Distributor may
retain the services of firms or individuals to act as dealers (the "Dealers") of
the Shares in connection  with the offering of Shares,  and (b) the  Distributor
may make  payments  for such  services to the Dealers out of the fee paid to the
Distributor hereunder,  any deferred sales charges imposed by the Distributor in
connection  with the  repurchase  of Shares,  its  profits  or any other  source
available to it; and

         WHEREAS,  the Trust recognizes and agrees that the Distributor may (but
is not required to) impose certain deferred sales charges in connection with the
repurchase  of Shares by the Fund,  and the  Distributor  may retain (or receive
from the Fund, as the case may be) all such deferred sales charges; and

         WHEREAS, the Board of Trustees of the Trust, in considering whether the
Fund should adopt and implement this Plan, has evaluated such  information as it
deemed necessary to an informed  determination as to whether this Plan should be
adopted and implemented  and has considered such pertinent  factors as it deemed
necessary  to form the basis for a  decision  to use assets of the Fund for such
purposes,  and has  determined  that there is a reasonable  likelihood  that the
adoption and  implementation  of this Plan will benefit the Fund and its Class C
shareholders;
<PAGE>

         NOW,  THEREFORE,  the Board of Trustees of the Trust hereby adopts this
Plan  for  the  Fund  as a plan  for  distribution  relating  to the  Shares  in
accordance with Rule 12b-1, on the following terms and conditions:

         1. As specified in the Distribution  Agreement,  the Distributor  shall
provide  facilities,  personnel  and a program  with respect to the offering and
sale of Shares. Among other things, the Distributor shall be responsible for any
commissions payable to Dealers (including any ongoing maintenance  commissions),
all expenses of printing (excluding  typesetting) and distributing  prospectuses
to prospective  shareholders  and providing  such other related  services as are
reasonably necessary in connection therewith.

         2. The Distributor shall bear all distribution-related  expenses to the
extent  specified  in the  Distribution  Agreement  in  providing  the  services
described in paragraph 1, including  without  limitation,  the  compensation  of
personnel  necessary  to provide such  services and all costs of travel,  office
expenses  (including  rent and  overhead),  equipment,  printing,  delivery  and
mailing costs.

         3. It is understood  that the  Distributor may (but is not required to)
impose  certain  deferred  sales  charges in connection  with the  repurchase of
Shares by the Fund and the  Distributor may retain (or receive from the Fund, as
the case may be) all such deferred  sales charges.  As additional  consideration
for all services  performed  and  expenses  incurred in the  performance  of its
obligations under the Distribution Agreement, the Fund shall pay the Distributor
a distribution  fee  periodically at a rate not to exceed 0.75% per annum of the
Fund's average daily net assets attributable to the Shares.

         4. As partial  consideration  for the personal  services and/or account
maintenance  services  performed  by  each  Dealer  in  the  performance  of its
obligations under its dealer agreement with the Distributor,  the Fund shall pay
each Dealer a service fee  periodically  at a rate not to exceed 0.25% per annum
of the portion of the average  daily net assets of the Fund that is  represented
by Shares  that are owned by  investors  for whom such  Dealer is the  holder or
dealer of record.  That portion of the Fund's  average daily net assets on which
the fees payable under this  paragraph 4 hereof are calculated may be subject to
certain  minimum amount  requirements  as may be  determined,  and additional or
different dealer qualification  standards that may be established,  from time to
time by the Distributor.  The Distributor  shall be entitled to be paid any fees
payable under this paragraph 4 hereof with respect to Shares for which no Dealer
of  record  exists  or  qualification  standards  have not  been met as  partial
consideration for personal services and/or account maintenance services provided
by the  Distributor  to the Shares.  The  service  fee payable  pursuant to this
paragraph 4 may from time to time be paid by the Fund to the Distributor and the
Distributor  will then pay these fees to Dealers on behalf of the Fund or retain
them in accordance with this paragraph.
<PAGE>

         5. The Fund understands that agreements between the Distributor and the
Dealers may provide for payment of commissions to Dealers in connection with the
sales of Shares and may provide for a portion (which may be all or substantially
all) of the fees payable by the Fund to the Distributor  under the  Distribution
Agreement to be paid by the Distributor to the Dealers in  consideration  of the
Dealer's services as a dealer of the Shares. Except as described in paragraph 4,
nothing  in this  Plan  shall be  construed  as  requiring  the Fund to make any
payment to any  Dealer or to have any  obligations  to any Dealer in  connection
with  services  as a dealer  of the  Shares.  The  Distributor  shall  agree and
undertake that any agreement entered into between the Distributor and any Dealer
shall  provide  that,  except as provided in paragraph 4, such Dealer shall look
solely to the Distributor for compensation for its services  thereunder and that
in no event shall such Dealer seek any payment from the Fund.

         6. The Fund shall pay all fees and expenses of any independent auditor,
legal counsel,  investment adviser,  administrator,  transfer agent,  custodian,
shareholder servicing agent, registrar or dividend disbursing agent of the Fund;
expenses  of  distributing  and  redeeming  Shares  and  servicing   shareholder
accounts; expenses of preparing, printing and mailing prospectuses,  shareholder
reports,  notices,  proxy  statements and reports to  governmental  officers and
commissions and to shareholders of the Fund,  except that the Distributor  shall
be responsible for the distribution-related expenses as provided in paragraphs 1
and 2 hereof.

         7.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         8. This Plan shall become  effective  upon (a) approval by a vote of at
least a "majority  of the  outstanding  voting  securities"  of Class C, and (b)
approval  by a vote of the Board of  Trustees  and a vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest in the  operation of the Plan or in any  agreement
related to the Plan (the "Qualified Trustees"),  such votes to be cast in person
at a meeting called for the purpose of voting on this Plan.

         9. This Plan shall continue in effect indefinitely;  provided that such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained,  this Plan shall expire 12 months after
the effective date of the last approval.

         10.  This Plan may be  amended  at any time by the  Board of  Trustees;
provided that this Plan may not be amended to increase  materially the amount of
permitted  expenses  hereunder without the approval of holders of a "majority of
the outstanding  voting securities" of Class C and may not be materially amended
in any case without a vote of a majority of both the Trustees and the  Qualified
Trustees. This Plan may be terminated at any time by a vote of a majority of the
Qualified Trustees or by a vote of the holders of a "majority of the outstanding
voting securities" of Class C.
<PAGE>

         11. The Fund and the  Distributor  shall provide the Board of Trustees,
and the Board of Trustees shall review, at least quarterly,  a written report of
the  amounts   expended  under  this  Plan  and  the  purposes  for  which  such
expenditures were made.

         12. While this Plan is in effect, the selection and nomination
of Qualified Trustees shall be committed to the discretion of the Trustees who
are not "interested persons" of the Trust.

         13. For the  purposes  of this Plan,  the terms  "interested  persons",
"majority of the outstanding  voting  securities" and "specifically  approved at
least  annually" are used as defined in the 1940 Act. In addition,  for purposes
of determining the fees payable to the Distributor  hereunder,  the value of the
Fund's net  assets  shall be  computed  in the  manner  specified  in the Fund's
then-current  prospectus and statement of additional information for computation
of the net asset value of the Shares of the Fund.

         14. The Trust shall  preserve  copies of this Plan,  and each agreement
related hereto and each report referred to in paragraph 11 hereof (collectively,
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  record  shall be kept in an easily
accessible place for the first two years of said record-keeping.

         15. This Plan shall be construed in accordance with the laws of
The Commonwealth of Massachusetts and the applicable provisions of the 1940
Act.

         16. If any  provision  of this Plan shall be held or made  invalid by a
court decision,  statute, rule or otherwise, the remainder of the Plan shall not
be affected thereby.

by the  Distributor  to the Shares.  The  service  fee payable  pursuant to this
paragraph 4 may from time to time be paid by the Fund to the Distributor and the
Distributor  will then pay these fees to Dealers on behalf of the Fund or retain
them in accordance with this paragraph.
<PAGE>

         5. The Fund understands that agreements between the Distributor and the
Dealers may provide for payment of commissions to Dealers in connection with the
sales of Shares and may provide for a portion (which may be all or substantially
all) of the fees payable by the Fund to the Distributor  under the  Distribution
Agreement to be paid by the Distributor to the Dealers in  consideration  of the
Dealer's services as a dealer of the Shares. Except as described in paragraph 4,
nothing  in this  Plan  shall be  construed  as  requiring  the Fund to make any
payment to any  Dealer or to have any  obligations  to any Dealer in  connection
with  services  as a dealer  of the  Shares.  The  Distributor  shall  agree and
undertake that any agreement entered into between the Distributor and any Dealer
shall  provide  that,  except as provided in paragraph 4, such Dealer shall look
solely to the Distributor for compensation for its services  thereunder and that
in no event shall such Dealer seek any payment from the Fund.

         6. The Fund shall pay all fees and expenses of any independent auditor,
legal counsel,  investment adviser,  administrator,  transfer agent,  custodian,
shareholder servicing agent, registrar or dividend disbursing agent of the Fund;
expenses  of  distributing  and  redeeming  Shares  and  servicing   shareholder
accounts; expenses of preparing, printing and mailing prospectuses,  shareholder
reports,  notices,  proxy  statements and reports to  governmental  officers and
commissions and to shareholders of the Fund,  except that the Distributor  shall
be responsible for the distribution-related expenses as provided in paragraphs 1
and 2 hereof.

         7.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         8. This Plan shall become  effective  upon (a) approval by a vote of at
least a "majority  of the  outstanding  voting  securities"  of Class C, and (b)
approval  by a vote of the Board of  Trustees  and a vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest in the  operation of the Plan or in any  agreement
related to the Plan (the "Qualified Trustees"),  such votes to be cast in person
at a meeting called for the purpose of voting on this Plan.

         9. This Plan shall continue in effect indefinitely;  provided that such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained,  this Plan shall expire 12 months after
the effective date of the last approval.

         10.  This Plan may be  amended  at any time by the  Board of  Trustees;
provided that this Plan may not be amended to increase  materially the amount of
permitted  expenses  hereunder without the approval of holders of a "majority of
the outstanding  voting securities" of Class C and may not be materially amended
in any case without a vote of a majority of both the Trustees and the  Qualified
Trustees. This Plan may be terminated at any time by a vote of a majority of the
Qualified Trustees or by a vote of the holders of a "majority of the outstanding
voting securities" of Class C.
<PAGE>

         11. The Fund and the  Distributor  shall provide the Board of Trustees,
and the Board of Trustees shall review, at least quarterly,  a written report of
the  amounts   expended  under  this  Plan  and  the  purposes  for  which  such
expenditures were made.

         12. While this Plan is in effect, the selection and nomination
of Qualified Trustees shall be committed to the discretion of the Trustees who
are not "interested persons" of the Trust.

         13. For the  purposes  of this Plan,  the terms  "interested  persons",
"majority of the outstanding  voting  securities" and "specifically  approved at
least  annually" are used as defined in the 1940 Act. In addition,  for purposes
of determining the fees payable to the Distributor  hereunder,  the value of the
Fund's net  assets  shall be  computed  in the  manner  specified  in the Fund's
then-current  prospectus and statement of additional information for computation
of the net asset value of the Shares of the Fund.

         14. The Trust shall  preserve  copies of this Plan,  and each agreement
related hereto and each report referred to in paragraph 11 hereof (collectively,
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  record  shall be kept in an easily
accessible place for the first two years of said record-keeping.

         15. This Plan shall be construed in accordance with the laws of
The Commonwealth of Massachusetts and the applicable provisions of the 1940
Act.

         16. If any  provision  of this Plan shall be held or made  invalid by a
court decision,  statute, rule or otherwise, the remainder of the Plan shall not
be affected thereby.

         PLAN OF DISTRIBUTION with respect to the shares of beneficial  interest
to be designated "Class C" of MFS AGGRESSIVE GROWTH FUND (the "Fund"),  a series

2nd day of January, 1996.

                                  WITNESSETH:

         WHEREAS,  the Trust is engaged in business  as an  open-end  management
investment  company and is registered under the Investment  Company Act of 1940,
as amended (collectively with the rules and regulations  promulgated thereunder,
the "1940 Act"); and

         WHEREAS,  the Trust  intends to  distribute  the  shares of  beneficial
interest  (without  par  value)  of the  Fund  designated  Class C  Shares  (the
"Shares") in accordance with Rule 12b-1 under the 1940 Act ("Rule  12b-1"),  and
desires to adopt this  Distribution  Plan (the "Plan") as a plan of distribution
pursuant to such Rule; and

         WHEREAS, the Trust desires for MFS Fund Distributors,  Inc., a Delaware
corporation,  to  provide  certain  distribution  services  for  the  Fund  (the
"Distributor"); and

         WHEREAS,  the Trust has  entered  into a  distribution  agreement  (the
"Distribution  Agreement")  (in a form  approved by the Board of Trustees of the
Trust in a manner  specified  in Rule 12b-1) with the  Distributor,  whereby the
Distributor  will provide  facilities  and personnel and render  services to the
Fund in connection with the offering and distribution of the Shares; and

         WHEREAS,  the Trust  recognizes and agrees that (a) the Distributor may
retain the services of firms or individuals to act as dealers (the "Dealers") of
the Shares in connection  with the offering of Shares,  and (b) the  Distributor
may make  payments  for such  services to the Dealers out of the fee paid to the
Distributor hereunder,  any deferred sales charges imposed by the Distributor in
connection  with the  repurchase  of Shares,  its  profits  or any other  source
available to it; and

         WHEREAS,  the Trust recognizes and agrees that the Distributor may (but
is not required to) impose certain deferred sales charges in connection with the
repurchase  of Shares by the Fund,  and the  Distributor  may retain (or receive
from the Fund, as the case may be) all such deferred sales charges; and

         WHEREAS, the Board of Trustees of the Trust, in considering whether the
Fund should adopt and implement this Plan, has evaluated such  information as it
deemed necessary to an informed  determination as to whether this Plan should be
adopted and implemented  and has considered such pertinent  factors as it deemed
necessary  to form the basis for a  decision  to use assets of the Fund for such
purposes,  and has  determined  that there is a reasonable  likelihood  that the
adoption and  implementation  of this Plan will benefit the Fund and its Class C
shareholders;
<PAGE>

         NOW,  THEREFORE,  the Board of Trustees of the Trust hereby adopts this
Plan  for  the  Fund  as a plan  for  distribution  relating  to the  Shares  in
accordance with Rule 12b-1, on the following terms and conditions:

         1. As specified in the Distribution  Agreement,  the Distributor  shall
provide  facilities,  personnel  and a program  with respect to the offering and
sale of Shares. Among other things, the Distributor shall be responsible for any
commissions payable to Dealers (including any ongoing maintenance  commissions),
all expenses of printing (excluding  typesetting) and distributing  prospectuses
to prospective  shareholders  and providing  such other related  services as are
reasonably necessary in connection therewith.

         2. The Distributor shall bear all distribution-related  expenses to the
extent  specified  in the  Distribution  Agreement  in  providing  the  services
described in paragraph 1, including  without  limitation,  the  compensation  of
personnel  necessary  to provide such  services and all costs of travel,  office
expenses  (including  rent and  overhead),  equipment,  printing,  delivery  and
mailing costs.

         3. It is understood  that the  Distributor may (but is not required to)
impose  certain  deferred  sales  charges in connection  with the  repurchase of
Shares by the Fund and the  Distributor may retain (or receive from the Fund, as
the case may be) all such deferred  sales charges.  As additional  consideration
for all services  performed  and  expenses  incurred in the  performance  of its
obligations under the Distribution Agreement, the Fund shall pay the Distributor
a distribution  fee  periodically at a rate not to exceed 0.75% per annum of the
Fund's average daily net assets attributable to the Shares.

         4. As partial  consideration  for the personal  services and/or account
maintenance  services  performed  by  each  Dealer  in  the  performance  of its
obligations under its dealer agreement with the Distributor,  the Fund shall pay
each Dealer a service fee  periodically  at a rate not to exceed 0.25% per annum
of the portion of the average  daily net assets of the Fund that is  represented
by Shares  that are owned by  investors  for whom such  Dealer is the  holder or
dealer of record.  That portion of the Fund's  average daily net assets on which
the fees payable under this  paragraph 4 hereof are calculated may be subject to
certain  minimum amount  requirements  as may be  determined,  and additional or
different dealer qualification  standards that may be established,  from time to
time by the Distributor.  The Distributor  shall be entitled to be paid any fees
payable under this paragraph 4 hereof with respect to Shares for which no Dealer
of  record  exists  or  qualification  standards  have not  been met as  partial
consideration for personal services and/or account maintenance services provided
by the  Distributor  to the Shares.  The  service  fee payable  pursuant to this
paragraph 4 may from time to time be paid by the Fund to the Distributor and the
Distributor  will then pay these fees to Dealers on behalf of the Fund or retain
them in accordance with this paragraph.
<PAGE>

         5. The Fund understands that agreements between the Distributor and the
Dealers may provide for payment of commissions to Dealers in connection with the
sales of Shares and may provide for a portion (which may be all or substantially
all) of the fees payable by the Fund to the Distributor  under the  Distribution
Agreement to be paid by the Distributor to the Dealers in  consideration  of the
Dealer's services as a dealer of the Shares. Except as described in paragraph 4,
nothing  in this  Plan  shall be  construed  as  requiring  the Fund to make any
payment to any  Dealer or to have any  obligations  to any Dealer in  connection
with  services  as a dealer  of the  Shares.  The  Distributor  shall  agree and
undertake that any agreement entered into between the Distributor and any Dealer
shall  provide  that,  except as provided in paragraph 4, such Dealer shall look
solely to the Distributor for compensation for its services  thereunder and that
in no event shall such Dealer seek any payment from the Fund.

         6. The Fund shall pay all fees and expenses of any independent auditor,
legal counsel,  investment adviser,  administrator,  transfer agent,  custodian,
shareholder servicing agent, registrar or dividend disbursing agent of the Fund;
expenses  of  distributing  and  redeeming  Shares  and  servicing   shareholder
accounts; expenses of preparing, printing and mailing prospectuses,  shareholder
reports,  notices,  proxy  statements and reports to  governmental  officers and
commissions and to shareholders of the Fund,  except that the Distributor  shall
be responsible for the distribution-related expenses as provided in paragraphs 1
and 2 hereof.

         7.  Nothing  herein  contained  shall be deemed to require the Trust to
take  any  action  contrary  to its  Declaration  of  Trust  or  By-Laws  or any
applicable  statutory  or  regulatory  requirement  to which it is subject or by
which it is  bound,  or to  relieve  or  deprive  the Board of  Trustees  of the
responsibility for and control of the conduct of the affairs of the Fund.

         8. This Plan shall become  effective  upon (a) approval by a vote of at
least a "majority  of the  outstanding  voting  securities"  of Class C, and (b)
approval  by a vote of the Board of  Trustees  and a vote of a  majority  of the
Trustees who are not "interested persons" of the Trust and who have no direct or
indirect  financial  interest in the  operation of the Plan or in any  agreement
related to the Plan (the "Qualified Trustees"),  such votes to be cast in person
at a meeting called for the purpose of voting on this Plan.

         9. This Plan shall continue in effect indefinitely;  provided that such
continuance  is  "specifically  approved at least  annually" by a vote of both a
majority of the Trustees of the Trust and a majority of the Qualified  Trustees.
If such annual approval is not obtained,  this Plan shall expire 12 months after
the effective date of the last approval.

         10.  This Plan may be  amended  at any time by the  Board of  Trustees;
provided that this Plan may not be amended to increase  materially the amount of
permitted  expenses  hereunder without the approval of holders of a "majority of
the outstanding  voting securities" of Class C and may not be materially amended
in any case without a vote of a majority of both the Trustees and the  Qualified
Trustees. This Plan may be terminated at any time by a vote of a majority of the
Qualified Trustees or by a vote of the holders of a "majority of the outstanding
voting securities" of Class C.
<PAGE>

         11. The Fund and the  Distributor  shall provide the Board of Trustees,
and the Board of Trustees shall review, at least quarterly,  a written report of
the  amounts   expended  under  this  Plan  and  the  purposes  for  which  such
expenditures were made.

         12. While this Plan is in effect, the selection and nomination
of Qualified Trustees shall be committed to the discretion of the Trustees who
are not "interested persons" of the Trust.

         13. For the  purposes  of this Plan,  the terms  "interested  persons",
"majority of the outstanding  voting  securities" and "specifically  approved at
least  annually" are used as defined in the 1940 Act. In addition,  for purposes
of determining the fees payable to the Distributor  hereunder,  the value of the
Fund's net  assets  shall be  computed  in the  manner  specified  in the Fund's
then-current  prospectus and statement of additional information for computation
of the net asset value of the Shares of the Fund.

         14. The Trust shall  preserve  copies of this Plan,  and each agreement
related hereto and each report referred to in paragraph 11 hereof (collectively,
the  "Records")  for a period of six years  from the end of the  fiscal  year in
which  such  Record  was made and each  such  record  shall be kept in an easily
accessible place for the first two years of said record-keeping.

         15. This Plan shall be construed in accordance with the laws of
The Commonwealth of Massachusetts and the applicable provisions of the 1940
Act.

         16. If any  provision  of this Plan shall be held or made  invalid by a
court decision,  statute, rule or otherwise, the remainder of the Plan shall not
be affected thereby.
