Letter from the Chairman

Dear Contract Owners,
In 1999, MFS celebrates its 75th anniversary. The nation's first mutual fund --
our Massachusetts Investors Trust (MIT) -- was introduced to the public on
March 21, 1924. Since then, MFS Investment Management[RegTM], the company that
grew out of that original fund, has helped guide investors through many
economic and investment cycles, primarily by focusing on the long-term
opportunities created by an expanding global economy. As of December 31, 1998,
MFS manages nearly $100 billion, and the firm's 2,000 people serve almost four
million investors and their financial advisers worldwide.

One of the elements in the success of MIT did not exist before our founders
invented it in 1924. That is daily redemption. This feature, through which new
shares were created when people invested in MIT and were redeemed when people
sold, was an important change. As a result, the price of a mutual fund's shares
wasn't determined by supply and demand, but by the value of the securities
owned by the portfolio.

Another factor in our growth was the development of one of the industry's first
internal research departments in 1932. Unlike companies that rely on Wall
Street research reports, which can be used by many investors at the same time,
MIT's managers built its long-term track record by visiting companies, talking
to managers and competitors, and "kicking the tires" so they could judge the
quality and potential of each company's products and services for themselves.
Today, MFS has more than 100 full-time portfolio managers, stock analysts, and
credit analysts who track the equity and bond markets. That number includes
over 35 equity analysts who specialize in industries such as aviation, media,
technology, automobiles, and utilities.

While MIT introduced the daily redemption feature, that was not our only
invention. We also established the nation's first global bond fund, the first
high-yield municipal bond fund, and the first high-yield municipal closed-end
bond fund. MFS also was among the leaders in the mutual fund industry in
introducing variable annuity accounts.

We are proud of the record of MIT and of all the products offered by MFS, but
we are also proud of our long-standing relationship with financial advisers.
Not only do we believe investors can benefit from the advice of these experts
but, as was shown during the market volatility of 1998, people who work with
financial advisers are less likely to abandon their carefully designed, long-
term investment strategies.

Our ability to service your investment and information needs is also extremely
important to us. The Sun Life Annuity Service Center handles millions of
transactions and phone calls every year. Supporting the work of financial
advisers, promptly sending out statements and confirmations, and answering
hundreds of investors' questions every day are crucial elements in maintaining
long-term relationships with our contract owners.

If there is a common thread running through these milestones, it is our
unswerving commitment to providing you with the best possible investment
management and contract owner service, just as we have done for the past 75
years.

As we celebrate this anniversary, it is also a time for MFS to look ahead and
build on our 75 years of innovation and experience to help meet your investment
needs in the next century. We appreciate your confidence and welcome any
questions or comments you may have.

On behalf of the Board of Trustees,

Management Review and Outlook
Capital Appreciation Series

For the 12 months ended December 31, 1998, the Series provided a total return
of 28.70%, which compares to a 28.58% return for the Standard & Poor's 500
Composite Index (the S&P 500) for the same period. The S&P 500 is a popular,
unmanaged index of common stock total return performance.

The Series' strong performance can be attributed to some of our major
weightings performing very well, particularly technology sector holdings such
as Microsoft, Cisco, Intel, and EMC. These companies have been able to leverage
the worldwide drive toward higher productivity and lower cost structures that
are predominantly enabled by technology. This trend is apparent in industries
around the world and is a result of the current low-inflation scenario.
Companies are compensating for the inability to boost revenues through price
increases by turning to cost reduction and productivity enhancement as a means
of keeping earnings healthy. In Cisco's case, the company provides much of the
communications equipment that is the backbone of the Internet, and it has
benefited from the explosion of interest in the 'Net.

Additionally, holdings in our leisure sector such as Time Warner and Viacom
performed well, driven by their ability to fill the need for cable programming
and operations services as that medium expands. Radio broadcasters such as
Jacor, Clear Channel, and Heftel also performed well in the wake of major
consolidation in the industry. Consolidation has enabled broadcasters to offer
comprehensive packages to potential advertisers that are more compelling than
several small individual advertising buys covering one market. Additionally,
advertisers are aware that radio allows them to reach more consumers than other
electronic media thanks to that medium's high rate of out-of-home usage.
Retailers such as CVS and Rite Aid have performed well, buoyed both by
consolidation in the industry and favorable demographics that have resulted in
increased prescription volume as the population ages.

Even in a strong year, individual stocks can disappoint. Among our large
holdings that did not perform up to our expectations was Cendant, which had
difficulty due to accounting fraud in a company that it acquired. Though the
stock has rallied somewhat, it is still down for the year. We still like the
company's business model, however, and look forward to an increased share price
in the near future. Computer Associates missed its earnings estimates earlier
in the year and suffered as a result, though we feel the company is
fundamentally sound and is worthy of our confidence long term. Gillette was
working its way through a product transition from its old shaving system to its
new triple-blade shaving product. As it was clearing old inventory, the Asian
economic crisis came to a head and hurt the company's earnings as a result of
reduced demand from those nations.

Management Review and Outlook -- continued

With regard to the turmoil in Asian markets during the year, the portfolio
didn't have a lot of direct Asian exposure. During the U.S. market correction
in September and October, some of which was the result of weakness in the Asian
economies, we took the opportunity to add to technology holdings that still
displayed solid fundamentals, that could take advantage of the world's
increased reliance on technology, and that we felt would rebound once the worst
was over. Some of these names included Compuware, DST Systems, Galileo
International, and Oracle.

We lightened the portfolio's exposure to industrial goods and basic materials
because we felt those industries were in the process of a minirecession of
their own and were not as resilient as technology stocks in the current
environment. We also increased our health care holdings and added some of the
major pharmaceutical stocks because, though expensive, they offer strong
fundamentals and good earnings growth prospects.

We like to look at the current environment in the same way that we look at a
potential investment. This entails factors such as earnings growth, management
quality, secular economic trends, cash flow generation, and valuations. In
light of those factors, we think that gross domestic product (GDP) may grow on
the order of 2.5%, while inflation will remain low, at about 1.5%. Therefore,
we expect to see moderate growth. Many American companies that are global
leaders should continue to grow revenues and earnings as they consolidate their
leadership positions and leverage secular trends. One concern here is that
valuations in the market are fairly high as the result of significant amounts
of liquidity that were pumped into the economy from interest-rate cuts around
the world and a flight from international markets to U.S. equities. However, we
think we're closer to achieving stability in the next few months, which means
that valuations may level off as investors pay closer attention to earnings
growth. In general, we think investors should expect more moderate performance
from the stock market in the future. For our part, we will continue to focus on
companies that we believe can deliver the best earnings growth at the best
prices and generate strong cash flow.


Conservative Growth Series

For the 12 months ended December 31, 1998, the Series provided a total return
of 23.85%, which compares to a 28.58% return for the S&P 500.

The past year has been quite a wild one in the equity market, with a strong
first half followed by a warning correction in the late summer and early fall
and, finally, a strong fourth quarter. Through that volatility, the Series has
done well.

In the course of the year, we reduced a large overweighting in financial
services by about 10% because we believe that the credit trends, cost cutting,
and consolidation that have made many of those stocks attractive have run their
course. In the current low inflation, low interest rate economic environment,
we view stocks' valuations as less important than companies' abilities to
deliver consistent and reliable earnings. Therefore, the assets taken from the
financial services reductions were used to boost our holdings in technology and
health care stocks that we feel offer the type of earnings reliability this
market requires. Examples of these stocks include Microsoft and IBM in
technology and Pfizer and American Home Products in health care and
pharmaceuticals.

We believe that our research-focused investment discipline has helped us in
discerning which companies' earnings are intact and growing consistently. An
interesting example of our investment style can be found in our IBM holding.
IBM is a company that is known primarily as a hardware company but, in reality,
about 50% of its income comes from services and software. That's important
because hardware is a high-volatility, low-margin business that often carries a
high price-to-earnings ratio. Software and services represent the opposite type
of business -- low volatility, high margin -- and can generate steadier revenue
streams. When we started buying IBM earlier this year, its mid-teens multiple
reflected a hardware company, not a full-service technology provider. In
addition, the company had very solid cash flow and good earnings, and it was
engaged in a major stock buyback program, which we believe is good for
investors. In all, IBM is a perfect stock for the portfolio. It is a large-cap,
blue-chip company with shareholder-friendly management, it has a stock price
that we deem a value because it reflects only a portion of its business, and it
has been paying a dividend. A further boost to IBM's attractiveness is that the
company is at the beginning of a major hardware product cycle. Our investment
here has paid off handsomely thus far.

Looking ahead, we are predicting slower earnings growth for domestic equities
in 1999, as well as low inflation and low interest rates. The environment
dictates that we pay close attention to earnings consistency and reliability,
so we do not intend to modify our fundamental method for selecting stocks. Our
discipline and our research focus have proved to be sound, and we believe our
approach will continue to work in the future.


Emerging Growth Series

For the 12 months ended December 31, 1998, the Series provided a total return
of 33.88%. This compares to a -2.55% return for the Russell 2000 Total Return
Index (the Russell 2000) and to a 28.58% return for the S&P 500. The Russell
2000 is an unmanaged index comprised of 2,000 of the smallest U.S.-domiciled
company common stocks (on the basis of capitalization) that are traded in the
United States on the New York Stock Exchange, the American Stock Exchange, and
NASDAQ.

The past year was a volatile one. While the U.S. economy appeared to be in good
shape, helped by nonexistent inflation and several easings of interest rates by
the Federal Reserve Board (the Fed), the rest of the world continued to be hurt
by the Asian contagion of slow growth and devaluation. The uncertainty in
global markets and the prospect for a deceleration in U.S. economic growth thus
increased the appeal of liquidity and of companies whose businesses were less
subject to the vagaries of international economies. As a result, the
mid-capitalization companies in the Series performed better than the
portfolio's larger holdings, as did companies that had little overseas
exposure.

The Series continued to benefit from strong performance in technology, its
largest sector and one in which earnings were surprisingly robust despite
issues relating to Asia. Stocks that contributed to performance included
Compuware, Cisco Systems, Microsoft, Oracle, and Sun Microsystems, all of whose
products were in solid demand by corporations seeking enhanced productivity.
Deregulation and the rapid growth of data services in the telecommunications
industry boosted the value of holdings such as MCI WorldCom and Global
Telesystems, and consumer demand was more vibrant than expected. This helped
successful specialty retailers such as Staples and Office Depot and also
provided a positive backdrop for food and drug retailing companies such as Rite
Aid and Fred Meyer, holdings whose strong pharmacy sales helped storewide
performance.

Management Review and Outlook -- continued

There were a few areas that did not do as well as we had hoped. Cendant, the
company created by the merger of HFS and CUC International, suffered because of
accounting irregularities at the former CUC. We think that a major
restructuring and refocusing of core businesses scheduled for 1999, combined
with a multimillion-dollar share buyback program, should help that company
improve its performance. Health maintenance organizations also disappointed due
to an imbalance between costs and pricing. We believe improved pricing and the
reduction of unprofitable businesses should help these companies in 1999.

Looking forward, we believe the fundamental outlook for emerging growth stocks
remains positive. We continue to think that we are at the beginning of a
slowdown in profit growth for many of the large-cap multinational companies
that make up the broad market averages. This is a positive for emerging growth
stocks, as we feel they should be able to grow faster than the overall economy.
Moreover, inflation and interest rates are both low, which provides a favorable
backdrop for valuations of emerging growth stocks.

Given this outlook, technology continues to be a key area of emphasis for the
Series since we think that software, networking, and telecommunications
equipment companies are likely to generate some of the strongest earnings
growth in the market. Another area that offers great promise is
telecommunications services, a sector in which mergers and the strong growth of
data transmissions are enhancing valuations. In our view, the companies that
can grow the fastest will be well rewarded by the marketplace. Thus, we believe
our strategy of searching out rapidly growing companies at reasonable prices
should benefit investors in 1999.


Managed Sectors Series

For the 12 months ended December 31, 1998, the Series provided a total return
of 12.25%, compared to a return of 28.58% for the S&P 500 and a 19.98% return
for the Lipper Capital Appreciation Fund Index. (The Lipper Mutual Fund indices
are unmanaged, net-asset-value weighted indices of the largest qualifying
mutual funds within their respective investment objectives, adjusted for the
reinvestment of capital gain distributions and income dividends.)

The past year was a volatile one in which performance was very selective. While
the U.S. economy appeared to be in good shape, helped by nonexistent inflation
and several easings of interest rates by the Fed, the rest of the world
continued to be hurt by the Asian contagion of slowing growth and devaluation.
The uncertainty in global markets and the prospect for a deceleration of U.S.
economic growth thus increased the appeal of liquidity, of companies with good
earnings growth, and of companies less subject to the vagaries of international
economies. As a result, larger-capitalization, consistent-growth companies and
those with little exposure to foreign economies contributed to performance. In
contrast, our small- and mid-cap holdings, as well as companies that depend on
global economic expansion, detracted from results.

More specifically, our holdings in energy and health care held back
performance. Energy stocks lagged because of softness in commodity prices.
Health care services were under pressure due to regulatory concerns and pricing
pressure from health maintenance organizations (HMOs). On a brighter note, our
specialty retail holdings in the food and drug industry performed well thanks
to continued industry consolidation and strong sales trends driven by solid
pharmaceutical sales. In addition, our holdings in technology, primarily
software, helped significantly, with strong appreciation in many of the leading
companies such as Microsoft, EMC, and Cisco Systems. Tyco International, the
Series' largest holding, was also a solid contributor as a result of
better-than-expected earnings results and good acquisitions.

We believe the coming year is likely to be one of change, much as 1998 was.
There are numerous questions. Will the U.S. and global economies go into
recession or accelerate as a result of the strong support on interest rates
provided by the Fed and the world's central banks? After several years of
above-average earnings growth, will unit growth be hard for companies to
achieve? Will deflation become a problem? All things considered, we believe
strong growth will be highly valued by investors in a world in which growth is
potentially scarcer. Thus, we have repositioned the portfolio with a focus on
finding companies that we believe can deliver superior relative earnings
growth. One way we can do this is by searching out companies with strong
franchises in high growth markets. As a result, technology is a key focus for
the Series. We are invested in software, networking, electronics, and
telecommunications service companies that are benefiting from the growth of the
Internet and the demand for more and faster communications. In health care, our
emphasis has shifted to companies that we believe can deliver technology-driven
unit growth -- both in devices and in the emerging pharmaceutical/biotechnology
fields. Successful specialty retailers that can find strategies that work well
and build on them will also have a place in the Series in 1999.

Looking forward, we believe the fundamental outlook for rapidly growing
companies remains positive. We continue to think that we are at the beginning
of a slowdown in profit growth for many of the large-cap multinational
companies. We think this is a positive for many of the smaller, rapidly growing
companies that should be able to grow faster than the broad market. Moreover,
inflation and interest rates are both low, a scenario that favors valuations of
rapidly growing companies.


Research Series

For the 12 months ended December 31, 1998, the Series provided a total return
of 23.61%, compared to a 28.58% return for the S&P 500.

Regarding the underperformance of the Series in comparison to the S&P 500, it
pays to bear in mind that this portfolio is truly a "best ideas" portfolio that
invests in what we feel are strong stocks regardless of their market
capitalizations or industry sectors. The roller-coaster ride that the market
has been on in the past few months has been driven by a narrow band of large-
capitalization, multinational companies, while the portfolio has significant
holdings in small- and mid-cap stocks. As a result, this portfolio does not
move in lock-step with the S&P 500, and we feel this flexibility will better
position the portfolio for long-term growth as the valuation gap between large
and small companies closes. We manage the portfolio through MFS[RegTM] Original
Research(SM), whereby we select companies that we feel can demonstrate earnings
growth in a variety of market conditions. This approach is very important in a
market such as this one in which we see few companies with the ability to raise
prices on their products.

While volatility bothers some investors, we believe it has created some
compelling bargains for what we feel are fundamentally sound companies. We
tried to take advantage of these during the market's downturn and added to
positions that had shown


                                                                               3
<PAGE>

Management Review and Outlook -- continued

weaker stock prices, but still demonstrated a sound fundamental outlook. Now,
with share prices rebounding across market capitalizations, we are paying
additional attention to companies' valuations. If we find instances of
valuations that are not supported by stocks' fundamentals, we will pare back
our positions in order to preserve gains for investors.

Two of our best ideas are MCI WorldCom and Lucent Technologies, both of which
are benefiting from the growth in demand for data communications products. We
believe MCI WorldCom has achieved the best strategic position in the industry
by focusing on the business market, which is the fastest-growing and most-
profitable segment of the data communications and Internet arena. It is also
expanding internationally and has been successfully taking market share from
larger, more-entrenched European telecommunications companies, many of which
were formerly nationalized industries. MCI is following the same
entrepreneurial model in Europe that it did in the United States, where it had
similar success in competition with AT&T. Finally, we feel the stock's current
valuation, or the ratio of its share price to its projected earnings, is
attractive at 22 times 1999 earnings estimates. Lucent Technologies is the
leading telecommunications equipment supplier in the United States. It
continues to benefit from increased capital spending, as telecommunications
companies such as MCI WorldCom and AT&T spend to accommodate the growth in data
and Internet traffic. Lucent is also increasing its market share overseas.
Though the stock is not inexpensive at 40 times its estimated 1999 earnings
growth, we believe that its strong growth justifies its valuation.

We continue to be overweighted in growth areas such as technology, health care,
and consumer staples. In technology the Series features Microsoft, our largest
holding, Cisco, Intel, and Oracle. We see positive prospects for continued
earnings growth in these companies as the world's corporations continue to
leverage all types of technology to reduce costs and boost productivity. In
health care, our weightings have changed little from one year ago and include
major pharmaceutical companies such as Pfizer, American Home Products, and
Bristol-Myers Squibb, all of which have strong product pipelines and should
benefit from the worldwide trend toward increased prescription volume. We also
have large holdings in consumer staples companies such as Colgate Palmolive and
Clorox, both of which we see as benefiting from continued consumer confidence
in a growing economy.

On the flip side, we are underweighted in a number of cyclical and
commodity-driven industries such as oil, chemical, and paper and forest
products. We see these industries suffering from pricing pressures that have
hurt their ability to generate consistent earnings growth.

MFS' commitment to research has not wavered since the company's inception in
1924. However, it's fair to say that the process has evolved. In 1924, MFS had
virtually no dedicated analysts. Portfolio managers did their own research and
made the investment decisions, and that heritage of informed stock selection is
deeply ingrained in our corporate culture. We started our internal research
department in 1932, and today we have a large global team of analysts who
examine individual companies firsthand by meeting with company managements,
interviewing customers, quizzing suppliers, and evaluating new products. This
experience is important in building our track record, as seasoned MFS
investment professionals pass along their knowledge and the corporate culture
to new analysts.


Total Return Series

For the 12 months ended December 31, 1998, the Series provided a total return of
11.71%, compared to returns of 28.58% for the S&P 500 and 9.49% for the Lehman
Brothers Government/Corporate Bond Index (the Lehman Index), an unmanaged,
market-value-weighted index of all debt obligations of the U.S. Treasury and
U.S. government agencies (excluding mortgage-backed securities) and
investment-grade U.S. corporate debt.

The Series benefited from both a strong equity and bond market in 1998, despite
some volatility. Equity returns varied widely based on "style." For example,
the unmanaged Russell 1000 Large-Capitalization Value Index increased 15.6%,
while the Russell 1000 Large-Capitalization Growth Index appreciated 38.7%. As
"value" managers, we focus more on financial services, basic industry, and
energy and utilities companies, while growth managers are more focused on
technology and health care companies. Although we had many stocks appreciate
dramatically in 1998, it was the technology and health care sectors that led
the market to new heights, groups that we have historically underweighted.

On the fixed-income side, U.S. Treasuries performed much better than corporate
debt. As economic and political turmoil spread throughout the Far East and
Latin America during 1998, there was a "flight to safety" that pushed up prices
on U.S. Treasuries. At the same time, bonds issued by U.S. corporations did not
keep pace because investors feared that corporate earnings would be hampered by
these global problems. As the Series tends to hold more corporate bonds than
Treasuries, our returns on the fixed-income side were strong but did not match
the returns of an "all-Treasuries" portfolio.

At the end of the year, the Series' allocation consisted of 58% in equities
(including convertible securities), 36% in bonds, and 6% in cash. This
allocation is consistent with prior years and is somewhat conservative. We
continue to have difficulty finding value in the equity markets because
price-to-earnings ratios are very high and dividend yields are at historical
lows. However, we do believe the insurance and the utilities and communications
sectors offer good risk/reward ratios, and we have major allocations in those
sectors.

Our goal for the coming year is to follow through with our value-oriented
style. We believe that our conservative stance offers the potential for good
returns should the equity and bond markets rise, while our balanced approach
can offer support should these markets undergo a correction.


Utilities Series

For the 12 months ended December 31, 1998, the Series provided a total return
of 17.54%. This compares to a 14.77% return for the Standard & Poor's Utilities
Index, an unmanaged, market-capitalization-weighted, total return index of all
utility stocks in the S&P 500.

Because of the market's volatility in 1998, there was a huge defensive move
into the utility sector, predominantly into large-cap, traditional electric
utility stocks, which are perceived to be high-quality investments. Investors,
many of whom probably had never owned utility stocks before, flooded the market
for large-cap electric utilities. In a twist on utility stocks' traditional
reputation as staid, surefooted investments, the sector became almost a
momentum play during the late summer as investors rushed to take advantage of
its surging performance. Among large-cap electric utilities, valuations were
stretched to unsupportable levels, which we believe reflected a lack of
critical analysis of the

Management Review and Outlook -- continued

stocks' fundamentals and more of a reaction based on fear. We believe this
surge may be running its course, and we are moving some of our electric
utilities assets into telecommunications stocks that we feel can support
stronger earnings growth.

At the same time, natural gas stocks underperformed, for a couple of reasons.
First, the unseasonably warm winter and spring of the past year depressed
demand and, second, low natural gas liquids commodity prices, coupled with
static processing, hurt earnings. However, this portfolio's focus is
predominantly on mid-cap stocks diversified across the utility spectrum. So
while we may not have benefited from the full surge in electric utilities, we
feel we have a broad portfolio of quality companies with high-quality
management teams and healthy earnings outlooks that have the ability to perform
well over the long term.

During the past year we have seen good performance from several of our
holdings. Mannesmann, a German telecommunications company, has performed well
thanks to its leadership position in the European wireless communications
market. The company, along with Olivetti, is part of an acquisition bid for
Cellular Communications International (CCIL), an American cellular phone
operator with substantial assets in Italy. CCIL's stock has been a strong
performer too, and we believe the combined entity will be a leader in the
rapidly expanding Italian telecommunications market.

PECO Energy, an electric utility based in Philadelphia, is also up strongly
this year thanks to good earnings growth and its ongoing successful transition
from a traditional regional electric utility to a national wholesale power
distributor. Endesa SA, a Spanish electric utility, has performed well as a
result of extensive restructuring in the Spanish electric industry and lower
interest rates in Europe.

Consolidation, particularly among the gas and electric utilities, has been an
underlying theme in the utilities market. At the moment, however, that frontier
is quiet, and we've been disappointed in the small number of deals announced in
1998. We've seen a few nice ones, such as an interesting gas/electric
combination between CMS Energy, an electric utility, and Duke Energy, which
sold its gas pipelines to CMS. But we haven't seen the big pairings that we saw
a couple of years ago, for two reasons. First, deregulation and restructuring
at the state level are still ongoing, and companies are waiting for the effects
of those trends to fully shake out before linking with other utilities. Second,
the Public Utility Holding Company Act is still a stumbling block to
consolidation. Interestingly, we have also seen some international deals that
have not come to fruition due to regulatory, economic, and cultural issues.

Looking ahead at the global utility market in 1999, we still see a number of
opportunities in Latin America that are relatively well insulated from the
region's macroeconomic problems. The Series has currently invested roughly 6%
of assets in Latin American utilities. In Asia, stock valuations are just not
attractive now. In Europe, utility stocks in northern Europe are getting
expensive, but we're seeing lots of opportunities in southern Europe,
especially in Italian and Greek telecommunications stocks and in Spanish
electric utilities. In the United States, we're finding the best values in
natural gas companies. We think their ability to snap back to robust earnings
growth in 1999 will be key to their share price performance in the future.


World Growth Series

For the 12 months ended December 31, 1998, the Series provided a total return
of 14.61%, compared to a 21.72% return for the Morgan Stanley Capital
International (MSCI) All Country World Index, a broad, unmanaged index of
global equities; a -2.55% return for the Russell 2000 Total Return Index (the
Russell 2000), an unmanaged 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; and a 28.58% return for the S&P 500.

The Series' performance was helped by its overweightings in U.S. technology and
European stocks and an underweighting in Japanese companies. However, this
performance was offset by an overweighting in the emerging markets, which were
abysmal performers across the board. Without a doubt, the disruption created by
Asia's economic problems was the single most important factor affecting global
markets during this period. Concerns surrounding Asia spread swiftly to Russia,
Latin America, and emerging Europe, resulting in widespread currency
devaluations, high interest rates, and slowing local economies. This, in turn,
dampened the profit outlook for some of our technology and large-cap
multinational companies with exposure to Asia and Russia. On a more positive
note, the United States and Europe have embarked on what appears to be the
beginning of a concerted effort to reduce interest rates. This should help
sustain growth in the United States and Europe, which in turn should fuel a
recovery in the emerging markets.

The United States remains one of the Series' primary markets because of low
inflation, low and declining interest rates, reasonably good economic growth,
and high corporate profits. We continue to emphasize U.S. technology, primarily
software, a sector in which the leading database, design automation, and
mainframe software companies such as BMC Software and Compuware are helping
corporations worldwide increase productivity. Another area we believe offers
solid potential is food and drug retailing, a sector in which companies are
benefiting from industry consolidation and strong pharmaceutical drug trends.
We also own a number of companies in the emerging telecommunications area, such
as MCI WorldCom and Global Telesystems, both of which are positioned to benefit
from global deregulation and increasing competition. We continue to add to our
positions in oil services and exploration. If global growth picks up in late
1999 or early 2000, we believe these stocks could perform well.

Meanwhile, we believe Europe offers the most opportunity of the developed
markets. European monetary union, which goes into effect in 1999, should be a
real positive for the region, which broadly speaking is at an earlier stage in
the economic cycle than the United States. Favorite countries include the
Netherlands, Italy, and Sweden. Compared to a year ago, the allocation to
Europe has increased because we've found companies there with more compelling
valuations than those in the United States. We're also finding more attractive
ideas in Japan. In general, we're looking for companies that we feel can
generate 15% or better annual growth at reasonable valuations. We've found
quite a few of these among consumer staples companies in Europe and the
export-oriented technology companies in Japan.

Some of the Series' better-performing holdings include software and networking
companies such as Compuware, BMC Software, and Cisco, all of which held up well
despite weakness among Asian customers. In Europe, financial stocks such as
Allied Irish Banks and Anglo Irish Bank contributed handsomely thanks to
earnings driven by strong local economies and a favorable interest-rate
environment.

We see better times ahead. Global markets should be helped by the concerted
action of the Fed and the Group of Seven major

Management Review and Outlook -- continued

industrialized nations, or the G7, to lower interest rates and keep the United
States and Europe on a growth track. We believe this should help the emerging
markets move toward recovery. We think there will be many fits and starts to
this recovery, so our strategy in the emerging markets is to invest in
companies and countries that we feel are positioned to come out of recession
quickly. In the United States, our focus is on companies that can generate
high-quality visible growth and those likely to benefit from a recovery in
overseas markets. In Europe and Japan, we will continue to focus on companies
generating 15% growth trading at what we view as attractive valuations.

(1) Investing in small or emerging growth companies involves greater risk than
    is customarily associated with more-established companies. These risks may
    increase unit price volatility.

(2) The Series may focus its investments in certain sectors, thereby increasing
    its vulnerability to any single economic, political, or regulatory
    development.

(3) Investments in foreign and emerging market securities may provide superior
    returns but also involve greater risk than U.S. investments. Investments in
    foreign and emerging market securities may be favorably or unfavorably
    affected by changes in interest rates and currency exchange rates, market
    conditions, and the economic and political conditions of the countries where
    investments are made. These risks may increase unit price volatility.

Notes to Performance Summary

All results are historical and assume the reinvestment of dividends and capital
gains. Investment return and principal value will fluctuate, and units, when
redeemed, may be worth more or less than their original cost. Past performance
is no guarantee of future results. Performance results reflect any applicable
expense subsidies and waivers, without which the results would have been less
favorable. Subsidies and waivers may be rescinded at any time. See the
prospectus for details.

   ##The Series has an expense offset arrangement which reduces the Series'
     custodian fee based upon the amount of cash maintained by the Series with 
     its custodian and dividend disbursing agent. For fiscal years ending after
     September 1, 1995, the Series' expenses are calculated without reduction 
     for this expense offset arrangement.
    @The total return information shown above does not reflect expenses that
     apply to the separate accounts established by Sun Life of Canada (U.S.) and
     Sun Life (N.Y.). Inclusion of these charges would reduce the total return
     figures for all periods shown.

     advisory fee for the Emerging Growth Series for the periods indicated. If 
     this fee had been incurred by the Series, the net investment income (loss)

   ++Not annualized.
    #Per share data are based on average shares outstanding.
   ##The Series has an expense offset arrangement which reduces the Series'
     custodian fee based upon the amount of cash maintained by the Series with 
     its custodian. For fiscal years ending after September 1, 1995, the Series'
     expenses are calculated without reduction for this expense offset 
     arrangement.
    @The total return information shown above does not reflect expenses that
     apply to the separate accounts established by Sun Life of Canada (U.S.) and
     Sun Life (N.Y.). Inclusion of these charges would reduce the total return
     figures for all periods shown.

[sec]For the period ended December 31, 1994, the investment adviser agreed to
     maintain the expenses of the Research Series, exclusive of investment
     advisory fees, at not more than 1.50% of average daily net assets. In
     addition, for both periods indicated below, the investment adviser
     voluntarily waived all or a portion of its advisory fee for the Research
     Series. To the extent actual expenses were over this limitation and/or the
     waiver had not been in place, the net investment income (loss) per share
     and the ratios would have been:

MFS/Sun Life Series Trust
Notes to Financial Statements

(1) Business and Organization
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 consisting of twenty-six separate Series (the Series) of
shares: Bond Series, Capital Appreciation Series*, Capital Opportunities Series
(formerly Value Series), Conservative Growth Series*, Emerging Growth Series*,
Equity Income Series, Government Securities Series, High Yield Series,
International Growth Series, International Growth and Income Series, Managed
Sectors Series*, Money Market Series, Massachusetts Investors Growth Stock
Series, MFS/Foreign & Colonial Emerging Markets Series, New Discovery Series,
Research Series*, Research Growth and Income Series, Research International
Series, Strategic Income Series, Total Return Series*, Utilities Series*, World
Asset Allocation Series, World Governments Series, World Growth Series*, World
Total Return Series, and Zero Coupon Series 2000 Portfolio. The Managed Sectors
Series, Utilities Series, and World Growth Series are non-diversified as that
term is defined in the Investment company Act of 1940, as amended. The shares
of each Series are sold only to variable accounts established by Sun Life
Assurance company of Canada (U.S.) and Sun Life Insurance and Annuity Company
of New York to Trust benefits under variable contracts issued by such
companies.

The Series 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. 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.

Investment Valuations - Equity securities listed on securities exchanges or
reported through the NASDAQ system are reported at market value using last sale
prices. Unlisted equity securities or listed equity securities for which last
sale prices are not available are reported at market value using last quoted
bid prices. Debt securities (other than short-term obligations which mature in
60 days or 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. Short-term obligations, which mature in 60
days or less, are valued at amortized cost, which approximates market value.
Non-U.S. dollar denominated short-term obligations are valued at amortized cost
as calculated in the foreign currency and translated into U.S. dollars at the
closing daily exchange rate. Options listed on commodities exchanges are
reported at market value using closing settlement prices. Over-the-counter
options on securities are valued by brokers. 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.

Repurchase Agreements - Certain Series may enter into repurchase agreements
with institutions that the Series' investment adviser has determined are
creditworthy. Each repurchase agreement is recorded at cost. The Series
requires that the securities collateral in a repurchase transaction be
transferred to the custodian in a manner sufficient to enable the Series to
obtain those securities in the event of a default under the repurchase
agreement. The Series monitors, on a daily basis, the value of the collateral
to ensure that its value, including accrued interest, is greater than amounts
owed to the Series under each such repurchase agreement. Certain Series of the
Trust, along with other affiliated entities of Massachusetts Financial Services
Company (MFS), may utilize a joint trading account for the purpose of entering
into one or more repurchase agreements.

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 gains and losses on
investments that results from fluctuations in foreign currency exchange rates
is not separately disclosed.

Written Options - Certain Series may write call or put options in exchange for
a premium. The premium is initially recorded as a liability which is
subsequently adjusted to the current value of the options contract. When a
written option expires, the Series realizes a gain equal to the amount of the
premium received. When a written call option is exercised or closed, the
premium received is offset against the proceeds to determine the realized gain
or loss. When a written put option is exercised, the premium reduces the cost
basis of the security purchased by the Series. The Series, 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.

Forward Foreign Currency Exchange Contracts - Certain Series of the Trust 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. The
Series may enter into forward contracts for hedging purposes as well as for
non-hedging purposes. For hedging purposes, the Series may enter into contracts
to deliver or receive foreign currency it will receive from or require for its
normal investment activities. Each Series may also use

Notes to Financial Statements -- continued

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, the Series may enter into contracts with the intent
of changing the relative exposure of the Series' 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 as unrealized
until the contract settlement date. On contract settlement date, the gains or
losses are recorded as realized gains or losses on foreign currency
transactions.
Investment Transactions and Income - Investment transactions are recorded on
the trade date. Interest income is recorded on the accrual basis. All discount
is accreted for financial statement and tax reporting purposes as required by
federal income tax regulations. Dividends received in cash are recorded on the
ex-dividend date. Dividend and interest payments received in additional
securities are recorded on the ex-dividend or ex-interest date in an amount
equal to the value of the security on such date.
Fees Paid Indirectly - Each Series' custody fee is calculated as a percentage
of each Series' month end net assets. The fee is reduced according to an
arrangement that measures the value of cash deposited with the custodian by
each Series. This amount is shown as a reduction of expenses on the Statements
of Operations.
Tax Matters and Distributions - Each Series' 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 income,
including any net realized gain on investments. Accordingly, no provision for
federal income or excise tax is provided.
Each Series 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
the Series' tax return.
Distributions to shareholders are recorded on the ex-dividend date. The Series
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 net realized gains. During
the year ended December 31, 1998, the following amounts were reclassified due
to differences between book and tax accounting for currency transactions and
net operating losses. This change had no effect on the net assets or net asset
values per share.

(6) Line of Credit
Each Series and other affiliated funds participate in an $805 million unsecured
line of credit provided by a syndication of banks under a line of credit
agreement. Borrowings may be made to temporarily finance the repurchase of
Series shares. Interest is charged to each Series, 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 fees allocated
to each Series for the year ended December 31, 1998, are as follows.

Company under a line of credit agreement. Borrowings may be made to temporarily
finance the purchase of securities, the redemption of shares, or emergency
expenses. At December 31, 1998, the amount outstanding for the Utilities Series
was $1,653,534.

Notes to Financial Statements -- continued

(7) Financial Instruments
Certain Series of the Trust may trade financial instruments with
off-balance-sheet risk in the normal course of its investing activities in
order to manage exposure to market risks such as interest rates and foreign
currency exchange rates. These financial instruments include written options
and forward foreign currency exchange contracts. The notional or contractual
amounts of these instruments represent the investment the Series has in
particular classes of financial instruments and does not necessarily represent
the amounts potentially subject to risk. The measurement of the risks
associated with these instruments is meaningful only when all related and
offsetting transactions are considered.

Forward Foreign Currency Exchange Contracts

Forward foreign currency purchases and sales under master netting agreements
for the Utilities Series amounted to a net receivable of $5,086 with Merrill
Lynch at December 31, 1998. Forward foreign currency purchases and sales under
master netting agreements for the Total Return Series amounted to a net payable
of $1,156 with Merrill Lynch at December 31, 1998. At December 31, 1998, the
Utilities Series and the Total Return Series had sufficient cash and/or
securities to cover any commitments under these contracts.


(8) Restricted Securities
Each Series of the Trust is restricted from investing more than a certain
amount in securities which are subject to legal or contractual restrictions on
resale. Such restrictions range from between 0% and 15% of the Series' net
assets. At December 31, 1998, the Research Series, Total Return Series, and
World Growth Series owned the following restricted securities (constituting
0.18%, 0.22%, and 0.42%, of the net assets of each Series, respectively) which
may not be publicly sold without registration under the Securities Act of 1933.
The Series does not have the right to demand that such securities be
registered. The value of these securities is determined by valuations furnished
by dealers or by a pricing service, or if not available, are valued at fair
value as determined in good faith by or at the direction of the Trustees.

Independent Auditors' Report

To the Trustees and Shareholders of MFS/Sun Life Series Trust:

We have audited the accompanying statements of assets and liabilities,
including the portfolios of investments, of Capital Appreciation Series,
Conservative Growth Series, Emerging Growth Series, Managed Sectors Series,
Research Series, Total Return Series, Utilities Series, and World Growth Series
(each a portfolio of MFS/Sun Life Series Trust) (the "Trust") as of December
31, 1998, the related statements of operations for the year then ended, the
statements of changes in net assets for the years ended December 31, 1998 and
1997, and the financial highlights for each of the years in the five-year
period ended December 31, 1998. These financial statements and financial
highlights are the responsibility of the Trust's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of the securities owned at
December 31, 1998 by correspondence with the custodian and brokers; where
replies were not received from brokers, we performed other auditing procedures.
An audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, such financial statements and financial highlights present
fairly, in all material respects, the financial position of each of the
respective portfolios of the MFS/Sun Life Series Trust at December 31, 1998,
the results of their operations, the changes in their net assets, and their
financial highlights for the respective stated periods in conformity with
generally accepted accounting principles.

                         MFS Prepares for the Year 2000


                                [Year 2000 Logo]


MFS Investment Management(R) is committed to the effective use of technology in
managing investments, delivering high-quality service to our fund shareholders,
and supporting the financial advisers who sell our products. With that in mind,
we created a separately funded Year 2000 Program Management Office in 1996
composed of a specialized staff reporting directly to MFS senior management. 

The Year 2000 (Y2K) problem arose because date fields in computers and software
applications have traditionally used two-digit codes. Since the dawn of the
computer age, the implied first two digits have been "1" and "9." In the year
2000, that can no longer be the case because computer applications may assume
"00" refers to 1900. Our team of dedicated business and technology managers,
working with outside experts, is taking reasonable steps to ascertain the Y2K
compliance of MFS' internal systems. We are also working with our vendors to
seek reasonable assurances that their systems are or will be compliant.

MFS realizes that investors are also concerned about whether the companies in
the Funds' portfolios are addressing their internal Y2K issues. As MFS'
portfolio managers and research analysts meet with the managements of portfolio
companies as part of the MFS(R) Original Research(SM) process, one of the many
factors they may consider is a company's Y2K preparedness.

Year 2000 compliance is an enormously complex, worldwide issue. No company or
institution can guarantee that it will be unaffected by the Y2K phenomenon.
While MFS is making an effort to ensure the integrity of its internal systems,
there are significant systems interdependencies in the domestic and foreign
securities markets, external vendor systems, and the internal business
environments of its portfolio companies. There can be no assurance that the
steps MFS has taken will be sufficient to avoid any adverse impact on the Funds.
However, MFS will continue to review and test its internal systems.

The potential hazard of computers having difficulty dealing with the year 2000
has been widely reported in the media. Essentially, the "Y2K" problem stems from
some computer software being written in a way that will handle only two digits
of a year rather than the full four digits. This becomes a problem when 2000 is
perceived as simply "00", with the result that the computer software interprets
the date as 1900 rather than 2000.

Sun Life began working on this problem in 1995 when a Company strategy for
dealing with the issue was approved by our systems management. It was apparent
that effective support from senior management was a key component to
successfully correcting Sun Life's systems. For this reason, in early 1996 Sun
Life's chairman and CEO delivered a clear mandate to make Y2K a top priority.
Since that time we have inventoried and assessed nearly 2000 systems around the
Company.

The vast majority of Sun Life's systems have already been tested, and, based on
these tests, have been certified as compliant. The current target date for
completion of Sun Life's certification program is the end of the first quarter
of 1999. Even though relatively few Y2K bugs were actually found during
analysis, it has been Sun Life's policy to test every system before it can be
certified as compliant. The price tag for this massive project has been steep --
over $100 million (Cdn). However, we consider the money well spent when it means
that Sun Life can move into the year 2000 and beyond confident that our systems
will support Sun Life's position as a leader in the financial services industry.

The preceding is a Year 2000 Readiness Disclosure pursuant to the Year 2000
Readiness Disclosure Act enacted by the United States Congress on October 19,
1998.
