LETTER FROM THE CHAIRMAN

DEAR CONTRACT OWNERS,

It has been almost two years since financial turmoil began to rock markets in
Asia, Russia, and Latin America. Even developed markets such as Europe and the
United States were not immune. In the U.S. equity market, for example, investors
focused on a narrow group of 50 of the largest-company growth stocks because
they seemed to offer less volatility in uncertain times. Fixed-income investors
also became more concerned about risk, moving money into U.S. Treasury
securities and out of corporate and municipal bonds and mortgage-backed
securities.

The narrowness of the market was just one of three broad issues that dominated
the U.S. equity market until recently. The other two were a slowdown in
corporate earnings growth and high valuations, with stocks of many companies
selling at extremely high prices relative to their earnings.

Although these have been challenging issues, we now see signs that we feel
demonstrate each one is changing for the better. Today, we believe the markets
are presenting more opportunities for investors to diversify, for our portfolio
managers to find good values, and for us to show the benefits of staying with
our long-term objectives and strategies. Investors seem to be regaining
confidence in a wider range of companies. Stocks of some small and mid-sized
companies, as well as some large industrial companies, have begun to perform
better in the past few months than they had for the previous year or so. These
companies appear to have benefited from early signs of stability in emerging
markets and a continuation of economic growth in the United States.

U.S. companies also have produced better earnings. Corporate earnings were, on
average, relatively flat in 1998. However, we expect earnings to grow 12% to 14%
this year because more companies have benefited from the strong economy and from
aggressive consolidation and cost-cutting measures they have taken over the past
several years.

Based on their earnings projections, our analysts estimate that the U.S. stock
market is still about 30% overvalued. While there has been some shift to a wider
group of stocks, many investors are still focusing on the large-company stocks.
As a result, most of the overvaluation is in the 50 largest stocks in the
Standard & Poor's 500 Composite Index (the S&P 500), a popular, unmanaged index
of common stock total return performance. That means about 450 stocks are
selling at more attractive prices, particularly given what we see as the
improved earnings outlooks for these and many small and mid-sized companies not
in the S&P 500. These companies also benefit from consolidation, cost cutting,
and global growth. Because they are smaller, they may be able to respond to
these changes more quickly, and thus they have the potential to grow faster than
the big companies.

The fixed-income markets, meanwhile, seem to be approaching the level of
relative stability they enjoyed before the Asian turmoil. Some credit for this
stability goes to the Federal Reserve Board (the Fed), which has reassured
investors that it will act to prevent rapid economic growth from causing higher
inflation and reduced purchasing power. Also, once investors saw that the
overseas turmoil had little, if any, effect on the financial strength of most
domestic bond issuers, the major non-Treasury markets -- corporate, municipal,
and mortgage -- began to rebound. Our portfolio managers are now finding more
opportunities to buy bonds with relatively stable prices and attractive yields.

The past two years have challenged investors. However, we believe we are well
positioned for the current environment because our analysts and portfolio
managers continue to rely on MFS-Registered Trademark- Original Research-SM- to
help evaluate the long-term investment potential of each holding being
considered for our portfolios. Also, we believe our discipline of staying with
our clearly defined investment strategies can help us offer investment products
with the potential to sustain returns over a variety of market cycles.

We appreciate your confidence and welcome any questions or comments you may
have.

Respectfully,

/s/ John D. McNeil

MANAGEMENT REVIEW AND OUTLOOK

BOND SERIES
For the six months ended June 30, 1999, the Series provided a total return of
- -1.69%, which compares to a -1.73% return for the average corporate debt "BBB"-
rated fund tracked by Lipper Analytical Services, Inc., an independent firm that
reports mutual fund performance. The Series' return also compares to a -2.28%
return for the Lehman Brothers Government/Corporate Bond Index (the Lehman
Index). The Lehman Index is an unmanaged, market-value-weighted index of U.S.
Treasury and government-agency securities (excluding mortgage-backed securities)
and investment-grade debt obligations of domestic corporations.

At the beginning of 1999, the Series' performance still was being impacted
negatively by ongoing turmoil in emerging markets and last summer's Russian bond
default. Because of these events, investors moved money into what they saw as
the safest securities -- U.S. Treasuries. As a result of the higher demand,
interest rates on Treasuries fell while rates on everything else, including
emerging market and corporate debt, increased. This

                                                                               1
<PAGE>
MANAGEMENT REVIEW AND OUTLOOK -- continued
sequence of events hurt the Series because we had a relatively heavy position in
corporate bonds.

In recent months, however, emerging markets have begun to rebound, and the
continuing strength of the U.S. economy, along with low U.S. inflation, is
supporting corporate bonds. The Series' largest positions are in securities of
U.S. corporations with strong and improving credit fundamentals, and we have
added to those positions recently. We also have begun to re-enter emerging
markets, but we are investing only in countries that we think have made the most
progress toward economic reform, such as Mexico and South Korea.

The Series is at its maximum exposure of 20% to high-yield securities, and we
are maintaining this weighting. Many U.S. high-yield issuers have seen increased
sales as a result of the strong economy, which has helped them maintain healthy
balance sheets and meet their debt payments. We have decreased the Series'
weightings in mortgage-backed securities and U.S. government-agency securities
because we felt there were better opportunities in the corporate market.

At roughly 25% of the portfolio, our position in cyclical industries --
businesses that can benefit from strengthening economic cycles -- is its highest
in five years. We selectively are adding holdings in cyclical industries, such
as transportation and paper, that we think will perform well if the economy
remains strong. For example, we established a position in Union Pacific
Corporation. Not only is this company increasing shipments because of general
economic growth, but it is also a turnaround story. When Union Pacific acquired
Southern Pacific a few years ago, it had a lot of logistical problems
integrating the two railroad systems. But the company seems to have fixed most
of its operational problems and has regained any business it had lost to
truckers and other railroads. We added paper and packaging companies to the
portfolio because businesses need more boxes to ship their products to
customers.

The Series also has a relatively large position in entertainment and
telecommunications, a sector in which several companies' bond ratings have moved
up from the high-yield to the investment-grade category. These companies took on
a lot of debt in the early and mid-1990s to build networks and make some big
acquisitions. Now, their networks are providing revenue, and they have reaped
the benefits of their acquisitions by cutting costs, generating more cash flow,
and paying off debt. Examples include Time Warner, which bought Turner
Broadcasting, and MCI WorldCom, the result of the takeover of MCI by WorldCom.

Looking ahead, we think the fixed-income environment could become a little more
difficult as the year progresses. The economy grew very strongly in the fourth
quarter of 1998 and the first quarter of 1999, and it will be hard to sustain
such a rapid growth rate. If there is an economic slowdown, revenues could
decrease and some companies could have trouble meeting their debt payments.
Therefore, if we see any signs of slowing in the economy, we plan to reduce our
exposure to corporates and cyclicals and go back to more traditional holdings
such as utilities.

GLOBAL ASSET ALLOCATION SERIES
For the six months ended June 30, 1999, the Series provided a total return of
3.55%, which compares to returns over the same period for the following
unmanaged indices: 12.23% for Standard & Poor's 500 Composite Index (the S&P
500), a popular, unmanaged index of common stock total return performance, 4.11%
for the Morgan Stanley Capital International (MSCI) Europe, Asia, Far East
(EAFE) Index, an unmanaged index of international stocks; -1.07% for the Lehman
Brothers Aggregate Bond Index, an index of government and corporate bonds
including U.S. Treasury, agency, corporate bond, and mortgage-backed securities;
and -9.33% for the J.P. Morgan Non-Dollar Government Bond Index, an index of
international bonds.

The Series utilizes an investment process that combines elements of both
quantitative and fundamental research in our efforts to deliver high
risk-adjusted performance. A proprietary quantitative model assists us in
determining the top-level allocation to equity and fixed-income markets around
the world. Then, within each market, we base individual security selection on
MFS-Registered Trademark- Original Research-SM-.

Throughout the first half of 1999, we maintained what we considered a defensive
posture with respect to our
top-level equity weighting. This posture was based primarily on current high
valuations prevalent throughout global equity markets, which leave valuations
extremely vulnerable to negative news. In addition, the favorable interest-rate
environment which has supported the equity markets over the past several years
has become less favorable as rates increased. Global interest rates were
generally higher at the end of the period than at the start of the year, and the
Federal Reserve Board (the Fed) recently raised the federal funds rate by 25
basis points. We believe that any sign of unsustainable economic growth or
inflation would lead to further rate increases. While we did not benefit from
this defensive posture during the first half of the year, we feel that the
current risk-reward tradeoff at these valuation levels suggests that the risk is
greater to the downside and we will eventually be rewarded. We continue to
remain well diversified with almost half of our equity assets invested outside
the United States.

With respect to the fixed-income markets, we maintained an underweight position
in U.S. Treasury securities for the better part of this year, which contributed
positively to performance as interest rates have generally been on the rise. We
have been overweight in the European government bond markets because we believe
the slow growth expectations and anticipated convergence of interest

2

MANAGEMENT REVIEW AND OUTLOOK -- continued
rates in non-euro countries (for example, Denmark and Sweden) to euro rates may
benefit the portfolio. We also have held a large position in the Japanese bond
market since February. The emphasis on international bonds has contributed
positively to performance because European bond markets delivered better
performance than the U.S. bond market and the Japanese bond market has been the
best-performing government bond market so far this year. As we begin to see
signs of stronger growth in Europe and Japan, we may reduce our allocation to
international government bonds.

We have opportunistically invested in both the U.S. high yield and emerging debt
markets, tactically allocating between the high yield and emerging debt markets
in response to changing patterns of relative available reward. We emphasized
high yield bonds early in the year because they compared favorably to U.S.
Treasuries. When equity markets rebounded strongly in the fourth quarter of 1998
from the sell-off in July and August, credit markets did not recover to the same
degree and thus were undervalued coming into the start of 1999. As a result, we
captured much of the emerging market debt rally over the last several months
while managing to avoid the significant widening of spreads in May. We will
continue to seek to improve performance through relative value trades of this
nature going forward.

GLOBAL GOVERNMENTS SERIES
For the six months ended June 30, 1999, the Series provided a total return of
- -7.19%, which compares to a -7.17% return for the Salomon Brothers World
Government Bond Index (the Salomon Index), an index made up of government bonds
with remaining maturities of at least five years.

Almost all global fixed-income markets (the notable exception being Japan's)
were weak throughout the first half of 1999. By the end of 1998, bond markets
feared the worst after the emerging market crisis, and yields dramatically fell
in anticipation of a global recession. However, so far in 1999, global consumer
demand has not decreased. On the contrary, in many countries consumption is on
the increase, particularly in the United States and now in Europe.

As a result of a vibrant U.S. economy and the pick-up in global growth, the Fed
raised overnight rates by 25 basis points at the end of June, thereby partially
reversing their easing bias caused by the credit crisis of 1998. At the same
time, most other developed countries experienced higher interest rates because
their markets anticipated similar increases by central bankers.

During the first half of 1999, absolute returns for the portfolio were
negatively impacted by weak bond markets and a strong U.S. dollar. Relative to
the Salomon Index, returns were helped by our having shortened the duration of
the portfolio in anticipation of higher rates. In addition, an overweighting in
the U.S. dollar versus the euro and yen added to relative outperformance.
Relative to the Salomon Index, performance was hurt by overweight positions in
Sweden, Denmark, and a small weighting in emerging markets.

As economic growth has begun to pick up outside the United States, central
bankers have grown increasingly worried about demand/pull inflation, even though
there still appears to be little or no ability for manufacturers to increase
prices. If inflation were to become a problem, it would probably first become
apparent through wages, especially in the United States, where unemployment is
at all-time lows. Central bankers have adopted either a neutral position or a
bias toward raising interest rates in order to preempt situational inflation.
Short term, such a scenario will most likely result in higher interest rates.
Consequently, the portfolio will maintain a bias toward short duration until the
markets become more comfortable with the fact that restrictive monetary policy
is ultimately positive for bond yields in an environment with minimal inflation
pressures. The specific bond markets we think we will continue to favor will be
the larger core markets such as the United States and Germany, as well as less
developed markets such as Greece and Denmark, which are favorable candidates for
inclusion in European monetary union.

GLOBAL TOTAL RETURN SERIES
For the six months ended June 30, 1999, the Series provided a total return of
- -0.50%, which compares to a 6.23% return for the average global flexible fund
tracked by Lipper Analytical Services, Inc. The Series' return also compares to
a 9.62% return for the Lipper Global Flexible Fund Index and to a 2.01% return
for a benchmark made up of 60% of the MSCI World Index and 40% of the J.P.
Morgan Global Government Bond Index (the Morgan Index). The MSCI World Index is
a broad, unmanaged index of global equities; the Morgan Index is an aggregate of
actively traded government bonds issued by 13 countries, including the United
States, with remaining maturities of at least one year. The Lipper mutual fund
indices are unmanaged, net-asset-value-weighted indicies of the largest
qualifying mutual funds within their respective investment objectives, adjusted
for the reinvestment of capital gains distributions and income dividends.

The Series invests for total return in stocks and bonds. Our stock portfolio
emphasizes large, financially strong companies, particularly in the United
States, Japan, and Europe. Using MFS-Registered Trademark- Original
Research-SM-, we look for companies that have histories of market leadership and
strong earnings growth. On the fixed-income side, our holdings are virtually all
government-issued bonds from major European countries, the United States, and
Japan. Our philosophy is, if we need bonds to help cushion declines in the
world's stock markets, we want to hold high-quality bonds.

The Series' positions in technology stocks are lower than those of the indices,
or in the portfolios of many of our

                                                                               3
<PAGE>
MANAGEMENT REVIEW AND OUTLOOK -- continued
competitors, and this has detracted from performance. The technology sector has
been one of the most
powerful areas of the stock market but, because prices of technology stocks tend
to be quite volatile, we remain underweighted in them. In addition, we had fewer
Japanese and more European holdings than our competitors. While this
underweighting in Japan has served us well for several years, it hurt us in the
past few months because Japanese stocks have made big gains and European stocks
have underperformed.

The Series has benefited from good performance by Mannesmann, a German
telecommunications company, Tyco International, a U.S. conglomerate, and Takeda
Chemical, a Japanese pharmaceutical company that does a lot of export business.
Also, we've seen strong performance by Compass, a British food services company.
We believe these are four well-run businesses with steadily growing profits.

Until recently, our U.S. holdings focused on three major sectors:
pharmaceuticals, financial services, and energy. We have reduced our positions
in the first two sectors. Although our pharmaceutical and financial services
holdings performed well, we felt their prices were high, considering their
declining earnings growth. However, we have maintained our positions in energy,
including Exxon and Royal Dutch Petroleum. This sector has performed well lately
in response to rising oil and gas prices.

In other sectors, we have eliminated some underperforming stocks and
considerably reduced our position in others. For example, our position in
Tomkins (a British conglomerate involved in factory automation, energy, baking,
transportation, and other businesses) has been eliminated. At one point, Tomkins
was one of the 10 largest holdings in the portfolio, but the company's
management recently has had problems executing its strategy.

Meanwhile, we bought Cable & Wireless in the United Kingdom, Hellenic Telecom in
Greece, and Telecom Italia Mobile in Italy. The growth in telecommunications has
helped almost all of the major companies in this industry. We also bought Banco
Popular, a Spanish bank. We believe that it's a very well-run bank but, as
European banks continue to consolidate, Banco Popular could be bought out,
possibly at a premium.

Although the European economy has been relatively strong, it began to show some
weakness earlier this year. The portfolio's weighting in Europe has stayed about
the same over the past several months, but several of the holdings have been
changed. For example, we bought Castorama-Dubois, a rapidly growing French
retailer similar to Home Depot that has benefited from increasing consumer
spending in Europe.

Looking ahead, we expect to see gains in all three major areas of the world: the
United States, Europe, and perhaps Japan. Interest rates and inflation remain
low, and the U.S. economy has grown at a strong rate. The United States may pull
along all of the other major economies, with the possible exception of Japan,
which has to do more on its own to stimulate growth.

GOVERNMENT SECURITIES SERIES
For the six months ended June 30, 1999, the Series provided a total return of
- -2.03%, which compares to a -2.67% return for the average U.S. government fund
tracked by Lipper Analytical Services, Inc. The Series' return also compares to
a -1.14% return for the Lehman Brothers Government/Mortgage Index (the Lehman
Index), an unmanaged index of U.S. Treasury, government-agency, and
mortgage-backed securities.

The interest-rate sensitivity of the Series has been about the same as that of
the Lehman Brothers Intermediate Government Bond Index (an unmanaged index
comprised of issues of the U.S. government and its agencies with remaining
maturities of less than 10 years), which has helped limit its price volatility
in a period of rising interest rates. We reduced holdings of longer-maturity
bonds because their prices would decline the most sharply if interest rates
continued to rise. However, if interest rates do rise enough to slow the economy
over the next few months, we will consider slightly increasing the Series'
long-term bond position in an effort to gain additional yield.

The Series benefited from our response to the turmoil in investment markets
following last summer's Russian bond default. Because of that event, interest
rates on non-Treasury agency securities increased dramatically, and their yield
spreads to Treasuries widened. We were able to take advantage of this situation
by adding government-agency securities at what we felt were attractive yield
levels. This has benefited the Series because interest rates on these securities
have fallen, but their prices have risen less than interest rates on
comparable-maturity Treasuries.

In the near term, we think the bond markets will continue to look for signs that
could lead to an additional interest-rate increase by the Federal Reserve Board
(the Fed). Just as the bond markets have had to adjust to stronger economic
growth in the United States, they will now have to adjust to signs of economic
stability in Asia and Latin America and signs of renewed growth in Europe. While
we believe yields on two-year Treasury securities should stay in a relatively
narrow range, yields on Treasuries
with longer maturities should reflect investor perception about economic growth.
Interest rates may increase to rein in a surging economy and quell inflation
fears if investors believe growth is too strong. However, since we believe
inflation should remain in check, we think any rate increase will be limited and
will present us with an opportunity to buy select higher-yielding securities.

MANAGEMENT REVIEW AND OUTLOOK -- continued

HIGH YIELD SERIES
For the six months ended June 30, 1999, the Series provided a total return of
5.02%, which compares to a return of 3.56% for the average high current yield
fund tracked by Lipper Analytical Services, Inc. The Series' return also
compares to a 2.20% return for the Lehman Brothers High Yield Bond Index, an
unmanaged index of noninvestment-grade corporate debt, and to a 3.85% return for
the Lipper High Yield Bond Fund Index.

The Series has benefited from a favorable economic environment for high-yield
securities -- specifically, moderate economic growth and low inflation in the
United States. The continued strength of the U.S. economy in 1999 has helped
strengthen investor confidence in the high-yield market as companies generally
have posted improved operating results.

However, the Series' slight underweighting in the energy sector, plus the fact
that we owned higher-quality bonds within that sector, detracted from
performance. As oil prices rose recently, we missed the bond price rally by
medium-quality energy companies. At the same time, however, our focus on
high-quality issuers meant that we avoided the numerous bankruptcies among the
low-rated, high-yield energy companies earlier in the year.

We believe the telecommunications sector still offers the best investment
opportunities in the high-yield market. Since the deregulation of this industry
in 1996, several companies have issued high-yield bonds to help fund the
development of their communications networks. These companies have benefited
from the tremendous increase in voice and data traffic, which was driven in part
by the growth in Internet usage. Examples include MetroNet, a dominant
competitive local exchange company in Canada. Bonds issued by MetroNet
appreciated when it was announced that the company would merge with AT&T Canada,
an investment-grade company with considerably better financial resources.
Finally, our position in Nextel Communication, a company that provides wireless
telecommunications services, rose in value after Microsoft announced that it
would invest $600 million in the company.

The Series' second-largest industry is media. We have been investing in cable
companies since the mid-1980s. On its own, we think cable is a good, defensive
industry that tends to have steady revenue streams through varying economic
conditions. Now, cable television systems are being recognized as efficient ways
to deliver high-speed Internet services to the home, which makes this industry
even more attractive to us. An example of our cable television holdings is
Charter Communications.

The Series' overseas holdings are primarily in Europe, where our focus is the
same as on our domestic holdings. We like telecommunications and media companies
such as Esprit Telecom, a U.K.-based telecommunications company. Europe was
slower to deregulate these industries than the United States, but we now are
seeing more bonds being issued by cable and telecommunications companies in
Germany, France, Spain, and the United Kingdom.

INTERNATIONAL GROWTH AND INCOME SERIES
For the six months ended June 30, 1999, the Series provided a total return of
- -0.49%, which compares to returns of 6.90% for the Lipper International Funds
Index and 4.11% for the MSCI EAFE Index.

The Series' underweighting in Japan and our holdings in Europe hurt performance.
We were underweighted in Japan because we did not find enough companies that we
thought had favorable earnings growth outlooks. However, for the past several
months the Japanese stock market has performed very well, thanks in large part
to the influx of foreign money.

We will continue to be cautious on Japan until we see concrete signs of its
recovery. Lower interest rates have helped, but fundamental reforms of the
financial system are still needed. We are, however, maintaining positions in
some Japanese companies, particularly those with global franchises, such as
Canon, an electronic and photographic equipment manufacturer, and Takeda
Chemical,
a pharmaceutical company. These companies have production and distribution
facilities around the world,
so they do not need a vibrant Japanese economy to
be profitable. We also have positions in companies
attempting "western-style" restructurings.

Meanwhile, although the benefits of European monetary union (EMU) are taking
longer to develop than expected, we believe the common currency will in time
make European companies more competitive and profitable because they will have
to cut costs and be more efficient if they want to gain market share across
borders. Some European companies in the portfolio already seem to
be well on their way to achieving this goal, including Compass, a British food
services company, Pinault-Printemps, a major French department store chain, and
Mannesmann, a German metal-fabricating company that has turned itself into one
of the leading cellular telephone companies in Europe.

The Series has a very small exposure to emerging markets because it emphasizes
high-quality companies producing steady earnings, and emerging market stocks
tend to be quite volatile. We do own Panamerican Beverages, a Mexican bottling
company with plants throughout Latin America. We think Panamerican should be
able to capitalize on the region's emergence from recession.

Among U.S. holdings, Tyco International continues to perform well. The company
has made several good acquisitions and, through consolidation and cost cutting,
has gotten excellent value out of those acquisitions. We also like American
International Group (AIG), a large

                                                                               5

MANAGEMENT REVIEW AND OUTLOOK -- continued
multiline insurance company that we expect to be one of the first U.S. financial
services firms to benefit from the rebound of Asian markets. Other American
financial services companies are just getting their feet wet in the Far East,
but AIG has been involved in that region for several decades.

Going forward, we think there will be some economic slowing in the second half
of the year. Because of continued economic growth in the United States and
renewed growth in emerging markets, bond investors have put upward pressure on
interest rates to help compensate for the potential effects of inflation. Higher
interest rates could mean slower economic growth as well as reduced revenues for
some companies in the portfolio. But, whatever happens, we will continue to
select stocks based on companies' individual merits and long-term business
outlooks; macroeconomic considerations will be secondary.

MFS-REGISTERED TRADEMARK-/FOREIGN & COLONIAL EMERGING MARKETS EQUITY SERIES
For the six months ended June 30, 1999, the Series provided a total return of
29.24%. This compares to a 38.41% return for the MSCI Emerging Markets Free
(EMF) Index, a broad, unmanaged, market-capitalization-weighted index of
equities in emerging markets, and to a 35.10% return for the Lipper Emerging
Markets Funds Index.

The crisis in Russia in August of 1998, which triggered a widespread decline in
global financial markets, was the most significant factor in the Series' recent
underperformance. Although our weighting in Russia at the time made up less than
5% of the Series' total assets, the Russian government's decision to default on
its domestic debt and devalue the ruble had a broad negative impact on emerging
market investments.

However, once the immediate impact of the Russian crisis passed, investors
noticed that economic reforms were contributing to a gradual recovery in Asia.
Markets in the region began to rebound in the fourth quarter of 1998 following
their decline over the previous 18 months. This rebound triggered a wider
recovery in emerging markets, particularly in Asia and Latin America. The
rebound also was aided by central bankers around the world, who aggressively cut
interest rates last year in an effort to keep credit available. The excess
liquidity created by cheaper credit is now finding its way into emerging stock
markets. Also, commodity prices, led by oil, have recovered significantly in the
past few months, and emerging markets that depend on commodity exports have
benefited. Finally, we think there are now signs that U.S. economic growth is
accelerating and that the Japanese economy is beginning to recover thanks to
government spending that has boosted consumer and business demand.

The most recent catalyst for the improvement in emerging markets was the
devaluation of the Brazilian currency in January, which led to additional flows
of capital. We also have seen further evidence of an Asian recovery, especially
in South Korea and Thailand, where governments have taken aggressive measures to
reform their financial markets and curtail speculative development.

Because of what we see as an improved Asian investment climate, we have shifted
away from Europe, the Middle East, and Africa and toward Asia. We did this
because the former markets have not shown the signs of recovery we have seen in
Asia and because we believe there are more investment opportunities in Asia.
Specifically, we have added to our positions in South Korea, the Philippines,
Thailand, and Singapore. In South Korea, Pohang Iron and Steel is a major
holding that we believe will benefit from its strong global position in the
steel sector.

In Latin America, we have major positions in Brazil and Mexico. In Brazil, we
believe the utilities sector remains attractive due to steady earnings and cheap
prices relative to cash flow. A major Brazilian holding continues to be Telesp
Participacoes, a telecommunications company.

Looking ahead, we believe emerging market economies are beginning to benefit
from the aggressive fiscal and economic reforms most of them undertook in the
past year or so. However, we believe the near-term potential for corporate
earnings growth is greater in some of these markets than in others. Our outlook
is reflected in the portfolio's allocation to South Korea, Thailand, and Brazil.
We believe they should benefit from global investors' renewed interest in the
asset class.

MONEY MARKET SERIES
Interest rates on short-term (90-day) securities increased approximately 35
basis points between December 31, 1998, and June 30, 1999. The federal funds
rate began 1999 at 4.75%. On June 30 1999, the Federal Reserve Board (the Fed)
raised that rate by 25 basis points. Because of this, we targeted 35 days for
the average maturity.

We continue to limit the Series' investments to securities issued or guaranteed
by the U.S. Treasury, agencies, or instrumentalities of the U.S. government, as
well as to the highest-quality corporate and bank issues, in order to provide
maximum security against credit risk. On June 30, 1999, approximately 48% of the
portfolio was invested in commercial paper, with the balance invested in U.S.
government or government-guaranteed issues.

We expect short-term interest rates to remain flat to slightly higher over the
next few months.

Investments in the Series are not insured or guaranteed by the Federal Deposit
Insurance Corp. or any other government agency. Although the Series seeks to

STRATEGIC INCOME SERIES
For the six months ended June 30, 1999, the Series provided a total return of
2.06%, which compares to a 0.82% return for the average multisector income fund
tracked by Lipper Analytical Services, Inc. The Series' return also compares to
the following unmanaged indices: -2.28% for the Lehman Brothers
Government/Corporate Bond Index (the Lehman Index), -7.17% for the Salomon
Index, and 2.82% for the Credit Suisse First Boston High Yield Index (the Credit
Suisse Index). The Lehman Index is weighted by market value and consists of all
U.S. Treasury and U.S. government-agency debt and of all publicly issued
fixed-rate, nonconvertible, investment-grade domestic corporate debt. The Credit
Suisse Index is a portfolio priced by traders to mirror the performance of the
high-yield debt market.

The Series seeks to provide a competitive yield and to capitalize on what we
believe are the most favorable opportunities among a diversified range of
government and corporate fixed-income markets in the United States and overseas.
Over the past few months, we have increased our percentage of assets dedicated
to corporate bonds, reflecting our confidence in the momentum of the U.S.
economy. Also, we have increased our cash position because concerns about
interest-rate increases by the Fed have rattled the bond markets.

The Series' emerging market debt holdings and high-yield corporate bonds have
contributed to performance. Toward the end of last year, we began to see signs
of recovery in emerging markets and selectively bought bonds from these markets
at attractive prices. Since then, bond prices have increased steadily as
countries such as Thailand have taken meaningful steps toward economic reform.
Also, the Latin American recession was not as bad as people feared. There had
been concern that Brazil was going to default on its debt. That didn't happen,
primarily because the Brazilian government undertook important economic reforms
while keeping inflation in check. Also, the continued strength of the U.S.
economy in 1999 has helped the high-yield market rebound. Investor confidence in
this market is once again high as companies issuing high-yield bonds can
generate revenue and meet their debt payments.

The Series' corporate bonds also have helped performance. After last summer's
liquidity crisis in certain bond markets, investor concern about risk increased,
leading to an aggressive sell-off of high-yield and high-grade corporate bonds.
One sector that was hurt was convertible bonds, which can be exchanged into
stock of the companies that issue them. Because of the sell-off, many
convertible bonds fell to prices that were less than stock values. We took this
opportunity to buy select convertible bonds at what we viewed as attractive
prices, including Colt Telecom Systems in the United Kingdom, Singapore
Telecommunications, and Silicon Graphics in the United States, a company that
makes systems to produce 3-D computer images. All of these companies have strong
businesses, and their bonds performed very well after we bought them. We have
since sold all three positions because we felt their prices were at a point that
reflected the companies' full values.

At this time, we think the environment is still very favorable for bonds. The
European Central Bank recently lowered short-term interest rates by half a
percentage point. That pressured the rest of the world to lower -- or at least
not raise -- rates. In the United States, high productivity and steady economic
growth suggest that inflation is well contained. Inflation-adjusted interest
rates in the United States are high compared to other countries, which
means there is still room for U.S. rates to come down. We think bond prices in
the corporate and emerging market sectors could advance further because their
prices declined excessively as the result of last year's crisis.

ZERO COUPON SERIES, PORTFOLIO 2000
For the six months ended June 30, 1999, the Series provided a total return of
0.97%. Intermediate-term U.S. Treasury notes moved higher during the period,
with yields on two-year Treasuries ranging from 4.40% to 5.75%. The portfolio
consists of discounted coupon or principal payments that are stripped from U.S.
Treasury securities in order to provide a predictable and compounded rate of
return. With no interest payments prior to maturity, these portfolios are more
sensitive to interest-rate changes than comparable bond funds with similar
maturities. While there will be fluctuations within the portfolio subject to
interest-rate moves, all portfolio holdings are guaranteed by the U.S. Treasury
at maturity. (While the guarantees do not apply to the individual units of the
Series, they assure a specified return to contract owners who hold their units
to the maturity of the Series.)

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.

RETURNS SHOWN DO NOT REFLECT THE DEDUCTION OF THE MORTALITY AND EXPENSE RISK
CHARGES AND ADMINISTRATION FEES. PLEASE REFER TO THE ANNUITY PRODUCT'S ANNUAL
REPORT FOR PERFORMANCE THAT REFLECTS THE DEDUCTION OF THE FEES AND CHARGES
IMPOSED BY INSURANCE COMPANY SEPARATE ACCOUNTS.

(1) Government guarantees apply to individual securities only and not to prices
    and yields of units in a managed portfolio. See the prospectus for details.

(2) Lower-rated securities may provide greater returns, but they are also
    associated with greater-than-average risk. These risks may increase unit
    price volatility. See the prospectus for details.

(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. See
    the prospectus for details.

 ##  Each of 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.

  #  Per share data are based on average shares outstanding.
 ##  Each of 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.

MFS/SUN LIFE SERIES TRUST
NOTES TO FINANCIAL STATEMENTS (UNAUDITED)

(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,
Emerging Growth Series, Equity Income Series, Global Asset Allocation Series*
(formerly World Asset Allocation Series), Global Governments Series* (formerly
World Governments Series), Global Growth Series (formerly World Growth Series),
Global Total Return Series*, Government Securities Series*, High Yield Series*,
International Growth Series, International Growth and Income Series*, Managed
Sectors Series, Massachusetts Investors Growth Stock Series, Massachusetts
Investors Trust Series, MFS/Foreign & Colonial Emerging Markets Equity Series*,
Money Market Series*, New Discovery Series, Research Series, Research Growth and
Income Series, Research International Series, Strategic Income Series*, Total
Return Series, Utilities Series, and Zero Coupon Series, Portfolio 2000*. The
Global Asset Allocation Series, Global Governments Series, Global Growth Series,
Global Total Return Series, High Yield Series, Managed Sectors Series, Strategic
Income Series, and Utilities 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.

The High Yield Series 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.

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. Money
market instruments are valued at amortized cost, which the Trustees have
determined in good faith approximates fair value. The Trust's use of amortized
cost is subject to the Trust's compliance with certain conditions as specified
under Rule 2a-7 of the Investment Company Act of 1940. Futures contracts,
options, and options on futures contracts listed on commodities exchanges are
reported at market value using closing settlement prices. Over-the-counter
options on securities are valued by brokers. Over-the-counter currency options
are valued through the use of a pricing model which takes into account foreign
currency exchange spot and forward rates, 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 the Trustees.

Repurchase Agreements - Certain Series of the Trust may enter into repurchase
agreements with institutions that the Trust's investment adviser has determined
are creditworthy. Each repurchase agreement is recorded at cost. Such Series
require that the collateral in a repurchase transaction be transferred to the
custodian in a manner sufficient to enable the Trust to obtain those securities
in the event of a default under the repurchase agreement. The investment advisor
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 result from fluctuations in foreign currency exchange rates is not
separately disclosed.

Security Loans - Certain Series of the Trust may lend their securities to member
banks of the Federal Reserve System and to member firms of the New York Stock
Exchange or subsidiaries thereof. State Street Bank and Trust Company ("State
Street"), as agent, loans the securities to certain brokers (the "Borrowers")
approved by the Series. The loans are collateralized at all times by cash and/or
U.S. Treasury securities in an amount at least equal to the market value of the
securities loaned. State Street provides the Series with indemnification against
Borrower default. The Series bears the risk of loss with respect to the
investment of cash collateral.

                                                                              45

NOTES TO FINANCIAL STATEMENTS (Unaudited) -- continued

At June 30, 1999, the value of securities loaned and their cash and U.S.
Treasury collateral were as follows:

<TABLE>
<CAPTION>
Series                                                Value        Cash     U.S. Treasury
<S>                                                 <C>         <C>         <C>
- -----------------------------------------------------------------------------------------
Global Asset Allocation Series....................  $7,981,978  $8,115,726   $      5,000
Global Total Return Series........................   6,731,774   6,787,096             --
</TABLE>

Cash collateral is invested in short-term securities, which are included in the
Portfolio of Investments. A portion of the income generated upon investment of
the collateral is remitted to the Borrowers, and the remainder is allocated
between the Series and State Street in its capacity as lending agent. On loans
collateralized by U.S. Treasury securities, a fee is received from the Borrower,
and is allocated between the Series and State Street. Income from securities
lending is included in interest income on the Statement of Operations. The
dividend and interest income earned on the securities loaned is accounted for in
the same manner as other dividend and interest income.

Written Options - Certain Series of the Trust 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 Series' management on the direction of interest rates.

Futures Contracts - Certain Series of the Trust may enter into futures contracts
for the delayed delivery of securities or currency, or contracts based on
financial indices at a fixed price on a future date. In entering such contracts,
the Series is required to deposit with the broker, either in cash or securities
an amount equal to a certain percentage of the contract amount. Subsequent
payments are made or received by the Series each day, depending on the daily
fluctuations in the value of the contract, and are recorded for financial
statement purposes as unrealized gains or losses by the Series. The Series'
investment in futures contracts is designed to hedge against anticipated future
changes in interest or exchange rates or securities prices. Investments in
interest rate futures for purposes other than hedging may be made to modify the
duration of the portfolio without incurring the additional transaction costs
involved in buying and selling the underlying securities. Investments in
currency futures for purposes other than hedging may be made to change the
Series' relative position in one or more currencies without buying and selling
portfolio assets. Investments in equity index contracts or contracts on related
options for purposes other than hedging may be made when the Series has cash on
hand and wishes to participate in anticipated market appreciation while the cash
is being invested. Should interest or exchange rates or securities prices move
unexpectedly, the Series may not achieve the anticipated benefits of the futures
contracts and may realize a loss.

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 will enter into forward contracts for hedging purposes as well as for
nonhedging 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. The Series 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 nonhedging 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 contractual 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 premium and
original issue discounts are amortized or 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.

Certain Series of the Trust use the effective interest method for reporting
interest income on payment-in-kind (PIK) bonds. 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 nonrecurring or 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 expensed.

Fees Paid Indirectly - The Series' custody fee is calculated as a percentage of
the Series' month end net assets. The fee is reduced according to an arrangement
that measures the value of cash deposited with the custodian by the Series. This
amount is shown as a reduction of expenses on the Statement 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 taxable
income, including any net realized gain on investments. Accordingly, no
provision for federal income or excise tax is provided.

NOTES TO FINANCIAL STATEMENTS (Unaudited) -- continued

Distributions to shareholders are recorded on the ex-dividend date. The Trust
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 distributions from paid-in
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.

Realized gain is reported net of any foreign capital gains tax in the Statement
of Operations.

At December 31, 1998, the following Series had a capital loss carryforward for
federal income tax purposes which may be applied against any net taxable
realized gains of each succeeding year until the earlier of its utilization or
expiration.

(6) FINANCIAL INSTRUMENTS
Certain Series of the Trust may trade financial instruments with
off-balance-sheet risk in the normal course of their 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,
forward foreign currency exchange contracts, futures contracts, and swap
agreements.

The notional or contractual amounts of these instruments represent the
investment the Series have in particular classes of financial instruments and do
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. A summary of
obligations under these financial instruments at June 30, 1999, is shown below
and on the following pages.

Colonial Emerging Markets Equity Series, and Strategic Income Series owned the
following restricted securities (consisting of 0.74%, 2.50%, and 0.92% of the
net assets of each series, respectively) which may not be publicly sold without
registration under the Securities Act of 1933. The Trust 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 or brokers, or, if not
available, in good faith by or at the direction of the Trustees.

                      MFS' YEAR 2000 READINESS DISCLOSURE

       MFS Investment Management-Registered Trademark-, as an investment
       adviser and on behalf of the MFS portfolios, is committed to the
       effective use of technology in managing our portfolio investments,
       delivering high-quality service to MFS shareholders and contract
       owners, retirement plan participants and MFS' institutional
       clients, 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 comprised of a specialized
       staff reporting directly to MFS senior management.

       The Year 2000 (Y2K) problem arises because calendar-year fields in
       computers and software applications traditionally have used
       two-digit codes so that, for example, the year 1998 is coded as
       "98," with the "19" being implied. In the year 2000, unless
       necessary corrections have been made, computer applications may
       assume "00" refers to 1900 rather than 2000, thus resulting in
       systems failures or miscalculations. To address this issue, our
       team of dedicated business and technology managers, working with
       outside experts, is taking steps to ascertain the Y2K readiness of
       MFS' internal systems and is working with our external systems
       vendors to determine whether they expect their systems to be
       ready.

       MFS recognizes that fund shareholders, contract owners, and
       institutional clients also are concerned about whether the
       companies whose securities are held in their portfolios are
       addressing Y2K issues. As part of the MFS-Registered Trademark-
       Original Research(sm) process of evaluating portfolio investments,
       one of the many relevant factors that MFS' portfolio managers and
       research analysts may consider is a company's Y2K readiness. Each
       year, MFS' research analysts and portfolio managers conduct more
       than 1,000 on-site meetings with companies whose securities are,
       or may be, held in fund and client portfolios, and host an
       additional 1,500 meetings at MFS' headquarters. When assessing the
       Y2K readiness of these companies, MFS' research analysts and
       portfolio managers may rely upon discussions at these meetings as
       well as SEC disclosure documents and third-party reports.

       Y2K readiness is an enormously complex, worldwide issue. No
       company or institution can guarantee that it will be unaffected by
       the Y2K issue. While MFS is taking significant steps to protect
       the integrity of its internal systems, there can be no assurance
       that these steps will be sufficient to avoid any adverse impact on
       MFS shareholders of MFS funds, participants in retirement plans
       administered by MFS, or MFS' institutional clients.

       If you have further questions regarding MFS' Year 2000 Readiness
       Program, please visit our Web site at www.mfs.com or contact the
       MFS Year 2000 Program Management Office by e-mail at [email protected]
       or by letter at 500 Boylston Street, Boston, MA 02116-3741.

                                                                              57

                         YEAR 2000 READINESS DISCLOSURE

                                     [LOGO]

       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 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 project teams 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
       relatively few remaining systems will be certified compliant
       during the course 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.
