LETTER FROM THE CHAIRMAN

Dear Shareholders:
After more than six years of expansion, the U.S. economy appears to be
experiencing another year of moderate growth in 1997, although a few signs
point to the possibility of a modest rise in inflation during the year. On the
positive side, the pattern of moderate growth and inflation set over the past
few years now seems fairly well entrenched in the economy and, short of a
major international or domestic crisis, appears to have enough momentum to
remain on track for some time. Also, gains in such important sectors as
housing, automobiles, industrial production, and exports indicate a fair
amount of underlying strength in the economy. However, some reason for caution
can be seen in the continuing high levels of consumer debt and rising personal
bankruptcies, as well as in the ongoing tightness in labor markets, which
could add some inflationary pressures to the economy. Given these somewhat
conflicting indicators, we expect real (inflation-adjusted) growth to revolve
around 2% in 1997, which would represent a modest decline from 1996.
    We continue to urge U.S. equity investors to lower their expectations for
1997 and to point out that the impressive gains of the past two years are not
sustainable. Just as the slowdown in corporate earnings growth and increases
in interest rates in 1996 raised some near-term concerns, further interest
rate increases and an acceleration of inflation could negatively affect the
stock market in 1997. However, to the extent that some slowdown in earnings
means that the economy is not overheating, this could be beneficial for the
equity market in the long run. Also, we believe many of the technology-driven
productivity gains that U.S. companies have made in recent years will continue
to enhance corporate America's competitiveness and profitability. Therefore,
while we have some near-term concerns, we remain reasonably positive about the
long-term viability of the equity market.
    In the bond markets, conflicting signals over the strength of the economy
have created near-term volatility, while comments by Federal Reserve Board
Chairman Alan Greenspan late in 1996 and earlier this year created some
uncertainty about the Federal Reserve's next move. However, we expect the Fed
to maintain its anti-inflationary stance should signs of more rapid economic
growth and, particularly, of higher inflation resurface. While inflationary
forces largely remained in check in 1996, the continued strength in the labor
market means that a pickup in inflation is still possible. At the same time,
the U.S. budget deficit continues to decline and, as a percentage of gross
domestic product, is now less than 2%, which we consider a positive
development for the bond markets. Although interest rates may move higher over
the coming months, we believe that, at current levels, fixed-income markets
remain equitably valued.
    We appreciate your support and welcome any questions or comments you may
have.

Respectfully,

/s/ A. Keith Brodkin

PORTFOLIO MANAGERS' OVERVIEWS

MFS CORE GROWTH FUND
For the six months ended February 28, 1997, Class A shares of the Fund
provided a total return of 24.12% and Class I shares returned 24.30%. These
returns, which assume the reinvestment of distributions but exclude the
effects of any sales charges, compare to a 22.50% return for the Standard &
Poor's 500 Composite Index (the S&P 500), a popular, unmanaged index of common
stock performance.
    Four general themes best describe the Fund's current holdings, which are
built from the bottom up based on individual stock selection. First, the Fund
seeks companies with high unit sales growth, which supports above-average
revenue growth. The second theme pertains to companies that we believe could
exhibit accelerated earnings growth driven by new product cycles and/or
acquisitions. Third, the Fund seeks companies that are able to control their
own destiny via internal changes such as cost cutting or consolidation. This
encompasses companies with the potential to make higher-than-average levels of
incremental internal investment. Finally, the Fund seeks companies that, in
our opinion, have the potential to benefit from a fundamental mismatch in the
balance between supply and demand.

MFS EQUITY INCOME FUND
For the six months ended February 28, 1997, Class A shares of the Fund
provided a total return of 20.26% and Class I shares returned 20.16%. These
returns, which assume the reinvestment of distributions but exclude the
effects of any sales charges, compare to a 22.50% return for the S&P 500.
    The Fund's top holdings were in the financial services, utilities,
industrial goods and services, and energy sectors. Within financial services,
the Fund has increased its weighting in insurance stocks, an industry in which
companies are aggressively reshaping their business portfolios. The Fund has
reduced its exposure to gas pipelines, after a strong performance in 1996.
Currently, the Fund's utility holdings are concentrated in gas distribution
companies, high-quality, low-cost electric utilities, and well-positioned
local and long-distance telephone companies. The Fund has maintained exposure
to the commercial jet building cycle; however, some profits have been taken in
this sector, a strong contributor to performance in 1996. Energy holdings
remain focused in both international and domestic companies, which are seeing
improved returns despite being in lagging businesses, especially refining,
where we believe a slow recovery is underway.
    The Fund continues to seek holdings in companies that we anticipate will
provide attractive dividend yields and reasonable valuations, characteristics
that we believe could provide protection against price declines in a volatile
market.

MFS SPECIAL OPPORTUNITIES FUND
For the six months ended February 28, 1997, Class A shares of the Fund
provided a total return of 12.59% and Class I shares returned 12.78%. These
returns, which assume the reinvestment of distributions but exclude the
effects of any sales charges, compare to a 22.50% return for the S&P 500.
    The Fund continues to have the majority of its assets in common stocks
because we have found few interesting opportunities in the distressed and
high-yield markets. The Fund's holdings can be separated as follows: one-third
in equities of companies that have emerged from bankruptcy, such as Anacomp;
one-third in leveraged-company equities, such as Maxxam; and one-third in
companies that we feel have significant earnings power and that trade at a
substantial discount to their anticipated long-term growth rates, such as Tyco
International. The Fund has also benefited from being invested in companies
that have been taken over. Two recent examples include Loral and Eljer
Industries. The Fund will continue its value-oriented style of investing and
will patiently wait for the markets to present what we feel are more
interesting opportunities over time.

The Fund commenced operations on January 2, 1997 and, from that date through
February 28, 1997, provided a total return of 4.30%. This return, which

sales charges, compares to a 7.08% return for the S&P 500 for the same period.
    The investment strategy of the Fund is predicated on the assumption that
the U.S. economy will grow slowly during 1997 and that interest rates will
remain fairly stable. Given the longevity of the current economic recovery and
the high levels of consumer debt, we believe that the economic risks are on
the downside. During the second half of 1997, investors could become
increasingly concerned about slower growth or a recession during 1998. If this
scenario unfolds, then interest rates could move downward. The Fund is
positioned to anticipate this potential change in perception, with the bulk of
its investments in companies that we believe can sustain double-digit earnings
growth in this type of environment. Earnings ultimately drive stock prices,
and investors will bid up prices of companies that can achieve above-average
earnings growth.
    The Fund's current industry weightings reflect a fairly defensive posture
that is consistent with this economic scenario. While sector allocations have
been made, the Fund's holdings are diverse and spread across many industries.
For example, the Fund is significantly underweighted in the basic materials,
auto, and housing sectors. Conversely, it is overweighted in consumer staples
and health care. Industrial goods are overweighted but skewed toward aerospace
and defense companies that, we believe, should perform relatively well in a
slow-growth economy. Similarly, the retail weighting is greater than the
market's, but two-thirds of this is in supermarkets and drug stores. The
financial services weighting is close to that of the S&P 500, with an emphasis
on high-quality regional banks and insurance companies. The weightings in the
energy and utilities and communications sectors also approximate those of the
market. While we believe these holdings offer modest price appreciation, they
are viewed as the ballast in the portfolio. Emphasis has also been placed on
companies that have significant recurring revenue streams and participate in
dynamic, high-growth markets. Examples are First Data, IKON, and DST Systems.
For the same reasons, the bulk of the Fund's technology investments are in the
software industry.

MFS CONVERTIBLE SECURITIES FUND
The Fund commenced operations on January 2, 1997 and from that date through
February 28, 1997, provided a total return of 1.50%. This return, which
assumes the reinvestment of distributions but excludes the effects of any
sales charges, compares to a 2.53% return for the Merrill Lynch All
Convertibles Index, an unmanaged index of 509 convertible securities, and a
2.60% return for the average convertible securities fund for the same period
as tracked by Lipper Analytical Services, an independent firm that monitors
mutual fund performance.
    The Fund has taken an extremely defensive posture to preserve capital due
to what we feel are the stock market's current high valuation and its
increased volatility. Convertible securities comprise 88% of the portfolio
versus the required 65% minimum. Increased demand for the convertible asset
class has led to a more expensive convertible securities market, as
illustrated by the aggressive pricing of new issues. In response, the
portfolio is skewed toward convertibles that are technically cheap (i.e.,
those whose price movements correlate well with the upward price movements in
the underlying common stock) and that have above-average yield.
    The Fund's overall strategy is to invest in companies that are benefiting
from one or more of the following trends: industry consolidation, market
dominance, or cost containment. Performance was favorably impacted by
overweightings in industrial goods and services companies such as Browning
Ferris and U.S. Filter; consumer staples such as Dole Foods; retailers such as
Saks Fifth Avenue and K-Mart; financial services companies such as Conseco,
NationsBank, and Finova; and technology companies such as Baan and Xilinx.
    Performance has been hindered by basic materials companies such as RMI
Titanium and Titanium Metals and, to a lesser extent, by energy companies such
as Enron Oil & Gas and Devon Energy. A value-oriented approach will continue
to be used to evaluate company fundamentals and technical aspects of
convertible securities.

MFS NEW DISCOVERY FUND
The Fund commenced operations on January 2, 1997 and, from that date through
February 28, 1997, provided a total return of 0.90%. This return, which
assumes the reinvestment of distributions but excludes the effects of any
sales charges, compares to a -0.48% return for the Russell 2000 Total Return
Index, an index comprised of 2,000 of the smallest U.S.-domiciled company
common stocks that are traded on the New York Stock Exchange, the American
Stock Exchange, and NASDAQ.
    The Fund maintains significant weightings in technology, health services,
financial services, and lodging -- sectors that we believe will experience
sustainable earnings growth well in excess of that of the overall economy. The
Fund's favorable performance versus the Russell 2000 Index reflects the
exceptional strength shown by its financial services and lodging holdings. The
former, such as Franklin Resources and Reliastar Financial, are experiencing
strong asset and earnings growth, as individuals both in the United States and
abroad are paying increased attention to building retirement assets. The
portfolio has also seen strong gains in the shares of several operators of
high-end hotel chains, such as Renaissance Hotels and Wyndham Hotels. These
companies are experiencing rapid earnings growth, reflecting strong industry
supply/demand fundamentals. Due to the sell-off of technology shares early in
1997, these stocks have hindered the Fund's performance. However, we remain
convinced that the technology sector offers the single best secular growth
opportunity in our economy, and our holdings are concentrated in companies
that we believe are well positioned and attractively valued. As a result, we
expect holdings such as Cadence Design Systems to contribute materially to the
Fund's future performance.
    The Fund will continue to seek what we feel are attractively valued,
emerging growth companies that can provide exceptional long-term returns. Of
late, the performance of larger-company shares has significantly outpaced that
of smaller-company stocks. Additionally, growing worries about inflationary
pressures have prompted an ongoing sell-off in many high-quality emerging
growth stocks that we would, heretofore, have considered overpriced. As a result
of these factors, we are encountering a greater number of what we see as
attractive investment opportunities, and we remain optimistic about the Fund's
future prospects.

MFS RESEARCH INTERNATIONAL FUND
The Fund commenced operations on January 2, 1997 and, from that date through
February 28, 1997, provided a total return of -1.50%. This return, which
assumes the reinvestment of distributions but excludes the effects of any
sales charges, compares to a -1.87% return for the Morgan Stanley Capital
International EAFE (Europe, Australia, Far East) Index, an unmanaged index of
international stocks.
    The top five sectors in the Fund are technology (15.8% of assets),
financial services (15.7%), utilities and communications (10.9%), retailing
(10.2%), and industrial goods and services (10.0%).
    The three top holdings in the Fund, which uses a bottom-up, fundamental
approach to investing, are in the technology sector with Sony, Canon, and TDK
Corporation. We believe Sony's new digital product launches and strong product
pipeline offer the company significant opportunities, while management's
compensation is directly tied to the company's performance. Also, through
major distributors in Europe and Japan, Sony Pictures' new management team
will soon be able to capitalize on the 3,400 movie titles it has in its motion
picture bank. As a result, we anticipate that operating profits could grow at
an average of over 20% over the next couple of years.
    Canon's underlying operating growth should be at 12% in the coming year.
We feel that the company's valuation is currently cheap for a quality growth
company. TDK has strong proprietary technology in a number of high-growth
component markets. We expect these products to continue providing strong
earnings growth over the next couple of years.
    Our top holding in the utilities and communications sector is PowerGen, a
British electric utility. There is currently strong industry demand and
availability at PowerGen's plants. As a result, production should be higher
than expected, and market share should be around 20% to 21%. Several of our
top holdings are also in the retail sector. Companies such as ASDA, Kwik-Fit,
and Storehouse all offer what we believe is good earnings potential at
reasonable valuations. Within the financial services sector, several banks and
insurance companies in Hong Kong, Great Britain, France, and Japan have
demonstrated good earnings growth, which, coupled with substantial cost
savings, is yielding excellent results.

MFS SCIENCE AND TECHNOLOGY FUND
The Fund commenced operations on January 2, 1997 and, from that date through
February 28, 1997, provided a total return of 0.80%. This return, which
assumes the reinvestment of distributions but excludes the effects of any
sales charges, compares to a 1.47% return over the same period for the NASDAQ-
OTC Index, an unmanaged index of common stocks traded on NASDAQ. The Fund's
performance during this period also compares to a -1.05% return for the
average technology fund as tracked by CDA/Wiesenberger, an independent firm
that reports mutual fund performance.
    The Fund's holdings are focused in the computer software, networking,
computer services, and semiconductor sectors. We believe that the long-term
outlook for these sectors is highly favorable due to several key factors, such
as growth in unit shipments of personal computers, increases in computing
power, new products, and expansion of international markets. The Fund seeks
companies that are fast growing, have market share leadership, and have a
defensible strategic position. Top holdings include Computer Associates,
Synopsis, and Intel. All three dominate their respective market segments, are
highly profitable, and have recently introduced new products that could
potentially accelerate growth.
    The Fund's performance is significantly impacted by the performance of its
industry sectors. Year to date, the stocks in this area have been extremely
volatile. Fund performance has been negatively affected by market declines in
the software and networking sectors. The Fund has, however, used its cash
position to purchase stocks whose prices have come down due to market
volatility but which, we believe, have substantial prospects for appreciation.

*For the period from the commencement of the Fund's investment operations,
 January 2, 1996 to February 28, 1997.

All results represent past performance and are not an indication of future
results. Investment return and principal value will fluctuate, and shares,
when redeemed, may be worth more or less than their original cost. Past
performance is no guarantee of future results.

SEC results include the maximum 4.75% sales charge.

Class I share results include the performance and operating expenses (e.g.,
Rule 12b-1 fees) of Class A shares for periods prior to the commencement of
offering of Class I shares. Because operating expenses attributable to Class A
shares are greater than those of Class I shares, Class I share performance
would have been higher had Class I shares been outstanding during the entire
period. The Class A share performance included in the Class I share
performance has been adjusted to reflect the fact that Class I shares have no
initial sales load.

Performance results reflect any applicable expense subsidies and waivers,
without which the results would have been less favorable. Current subsidies
and waivers may be discontinued at any time.

NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

(1) Business and Organization
MFS Series Trust I (the Trust) is organized as a Massachusetts business trust
and is registered under the Investment Company Act of 1940, as amended, as an
open-end management investment company. The Trust presently consists of eight
Funds, as follows: MFS Cash Reserve Fund, MFS Managed Sectors Fund, MFS World
Asset Allocation Fund, MFS Aggressive Growth Fund, MFS Research Growth and
Income Fund, MFS Core Growth Fund* (the Core Growth Fund), MFS Equity Income
Fund* (the Equity Income Fund), MFS Special Opportunities Fund* (the Special
Opportunities Fund), MFS Blue Chip Fund* (the Blue Chip Fund), MFS Convertible
Securities Fund* (the Convertible Securities Fund), MFS New Discovery Fund* (the
New Discovery Fund), MFS Research International Fund* (the Research
International Fund) and MFS Science and Technology Fund* (the Science and
Technology Fund). Each Fund, except MFS Managed Sectors Fund, MFS World Asset
Allocation Fund and the MFS Special Opportunities Fund is diversified.

The Funds denoted with an asterisk (*) above are included within these financial
statements.

(2) Significant Accounting Policies
General -- The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.

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

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

Deferred Organization Expenses -- Costs incurred by each Fund in connection with
its organization have been deferred and are being amortized on a straight-line
basis over a five-year period beginning on the date of commencement of
operations of each Fund.

Forward Foreign Currency Exchange Contracts -- Each Fund may enter into forward
foreign currency exchange contracts for the purchase or sale of a specific
foreign currency at a fixed price on a future date. Risks may arise upon
entering into these contracts from the potential inability of counterparties to
meet the terms of their contracts and from unanticipated movements in the value
of a foreign currency relative to the U.S. dollar. Each Fund will enter into
forward contracts for hedging purposes as well as for non-hedging purposes. For
hedging purposes, each Fund may enter into contracts to deliver or receive
foreign currency they will receive from or require for their normal investment
activities. The Funds may also use contracts in a manner intended to protect
foreign currency-denominated securities from declines in value due to
unfavorable exchange rate movements. For non-hedging purposes, each Fund may
enter into contracts with the intent of changing the relative exposure of each
Fund's portfolio of securities to different currencies to take advantage of
anticipated changes. The forward foreign currency exchange contracts are
adjusted by the daily exchange rate of the underlying currency and any gains or
losses are recorded for financial statement purposes as unrealized until the
contract settlement date.

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

Short Sales -- The Special Opportunities Fund, the Convertible Securities Fund,
the New Discovery Fund and the Science and Technology Fund may enter into short
sales. A short sale transaction involves selling a security which a Fund does
not own with the intent of purchasing it later at a lower price. A fund will
realize a gain if the security price decreases and a loss if the security price
increases between the date of the short sale and the date on which the Fund must
replace the borrowed security. Possible losses from short sales can be greater
than losses from the actual purchase of a security. The amount of any gain will
be decreased, and the amount of any loss increased, by the amount of the
premium, dividends or interest a Fund may be required to pay in connection with
a short sale. Whenever a Fund engages in short sales, its custodian segregates
cash or U.S. Government securities in an amount that, when combined with the
amount of collateral deposited with the broker in connection with the short
sale, at least equals the current market value of the security sold short.

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

The Special Opportunities Fund and the Convertible Securities Fund can invest up
to 100% of its portfolio in high-yield securities rated below investment grade.
Investments in high-yield securities involve greater degrees of credit and
market risk than investments in higher-rated securities, and tend to be more
sensitive to economic conditions.

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

Fees Paid Indirectly -- Each Fund's custodian bank calculates its fee based on
each Fund's average daily net assets. The fee is reduced according to a fee
arrangement, which provides for custody fees to be reduced based on a formula
developed to measure the value of cash deposited with the custodian by each
Fund. This amount is shown as a reduction of expenses on the Statement of
Operations.

Tax Matters and Distributions -- Each Fund's policy is to comply with the
provisions of the Internal Revenue Code (the Code) applicable to regulated
investment companies and to distribute to shareholders all of its taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided. Each Fund files a tax
return annually using tax accounting methods required under provisions of the
Code which may differ from generally accepted accounting principles, the basis
on which these financial statements are prepared. Accordingly, the amount of net
investment income and net realized gain reported on these financial statements
may differ from that reported on each Fund's tax return and, consequently, the
character of distributions to shareholders reported in the financial highlights
may differ from that reported to shareholders on Form 1099-DIV. Foreign taxes
have been provided for on interest and dividend income earned on foreign
investments in accordance with the applicable country's tax rates and to the
extent unrecoverable are recorded as a reduction of investment income.
Distributions to shareholders are recorded on the ex-dividend date.

Each Fund distinguishes between distributions on a tax basis and a financial
reporting basis and requires that only distributions in excess of tax basis
earnings and profits are reported in the financial statements as a tax return of
capital. Differences in the recognition or classification of income between the
financial statements and tax earnings and profits which result in temporary
over-distributions for financial statement purposes, are classified as
distributions in excess of net investment income or accumulated net realized
gains.

Multiple Classes of Shares of Beneficial Interest -- The Funds offer Class A and
Class I shares. The two classes of shares differ in their respective shareholder
servicing agent, distribution and service fees. All shareholders bear the common
expenses of the Fund pro rata based on average daily net assets of each class,
without distinction between share classes. Dividends are declared separately for
each class. No class has preferential dividend rights; differences in per share
dividend rates are generally due to differences in separate class expenses.

(3) Transactions with Affiliates 
Investment Adviser -- Each Fund has an investment advisory agreement with
Massachusetts Financial Services Company (MFS) to provide overall investment
advisory and administrative services, and general office facilities. The
management fee is computed daily and paid monthly at an effective annual rate of
0.65% of average daily net assets for the Blue Chip Fund and the Convertible
Securities Fund, at an annual rate of 0.75% of average daily net assets for the
Core Growth Fund, the Equity Income Fund, the New Discovery Fund, the Science
and Technology Fund, and the Special Opportunities Fund, and at an annual rate
of 1.00% of average daily net assets for the Research International Fund. For
the period ended February 28, 1997, the investment adviser did not impose any of
its fee, which is reflected as a reduction of expenses in the Statement of
Operations.

Under a temporary expense reimbursement agreement with MFS, MFS has voluntarily
agreed to pay all of each Fund's operating expenses exclusive of management,
distribution and service fees. Each Fund in turn will pay MFS an expense
reimbursement fee not greater than 1.50% of average daily net assets of its
Class A shares. To the extent that the expense reimbursement fee exceeds each
Fund's actual expenses, the excess will be applied to amounts paid by MFS in
prior years. At February 28, 1997, the aggregate unreimbursed expenses owed to
MFS by each Fund amounted to:

</TABLE>

Each Fund pays no compensation directly to its Trustees who are officers of the
investment adviser, or to officers of each Fund, all of whom receive
remuneration for their services to each Fund from MFS. Certain of the officers
and Trustees of each Fund are officers or directors of MFS, MFS Fund
Distributors, Inc. (MFD) and MFS Service Center, Inc. (MFSC). The Trustees are
currently not receiving any payments for their services to each Fund.

Distributor -- MFD, a wholly owned subsidiary of MFS, as distributor, did not
receive any sales charges on sales on Class A shares of each Fund for the period
ended February 28, 1997.

The Trustees have adopted a distribution plan for Class A shares pursuant to
Rule 12b-1 of the Investment Company Act of 1940 as follows:

The Class A distribution plan provides that each Fund will pay MFD up to 0.50%
per annum of its average daily net assets attributable to Class A shares in
order that MFD may pay expenses on behalf of each Fund related to the
distribution and servicing of its shares. These expenses include a service fee
to each securities dealer that enters into a sales agreement with MFD of up to
0.25% per annum of each Fund's average daily net assets attributable to Class A
shares which are attributable to that securities dealer, a distribution fee to
MFD of up to 0.25% per annum of each Fund's average daily net assets
attributable to Class A shares, commissions to dealers and payments to MFD
wholesalers for sales at or above a certain dollar level, and other such
distribution-related expenses that are approved by each Fund. Distribution and
service fees under the Class A distribution plan are currently being waived.

Purchases over $1 million of Class A shares and certain purchases into
retirement plans are subject to a contingent deferred sales charge in the event
of a shareholder redemption within 12 months following such purchase. There were
no contingent deferred sales charges imposed during the period ended February
28, 1997 on Class A shares of each Fund.

Shareholder Servicing Agent -- MFSC, a wholly owned subsidiary of MFS, earns a
fee for its services as shareholder serving agent. The fee is calculated as a
percentage of the average daily net assets of each Fund at an effective annual
rate of 0.13%. Prior to January 1, 1997, the fee was calculated as a percentage
of the average daily net assets of Class A at an effective annual rate of up to
0.15%. MFSC is currently waiving its fee for an indefinite period.

(4) Portfolio Securities 
Purchases and sales of investments, other than purchased option transactions,
U.S. government and short-term obligations, were as follows:

(6) Line of Credit
Each Fund entered into an agreement which enables it to participate with other
funds managed by MFS in an unsecured line of credit with a bank which permits
borrowings up to $400 million, collectively. Borrowings may be made to
temporarily finance the repurchase of Fund shares. Interest is charged to each
fund, based on its borrowings, at a rate equal to the bank's base rate. In
addition, a commitment fee, based on the average daily unused portion of the
line of credit, is allocated among the participating funds at the end of each
quarter. The commitment fee allocated to each Fund for the period ended February
28, 1997, were as follows:

(7) Restricted Securities
Each Fund may invest not more than 15% of its net assets in securities which are
subject to legal or contractual restrictions on resale. At February 28, 1997,
the Research International Fund and the Special Opportunities Fund owned the
following restricted securities (consisting of 2.4% and 0.6% of their net
assets, respectively). Each Fund does not have the right to demand that such
securities be registered. The value of these securities is determined by
valuations supplied by a pricing service of brokers or, if not available, in
good faith by or at the direction of the Trustees.
