Dear Variable Contract Owner:

Over the course of the past year, both the
domestic economy and equity markets have been        [PICTURE OF THOMAS J. LEE,
moving in a generally positive direction as              PRESIDENT AND VICE 
measured by key economic indicators and broad-         CHAIRMAN APPEARS HERE]
based market indices. International markets have
also been generally positive, though emerging
markets have shown a more robust rate of growth.
However, these positive returns have not come
without volatility.

To quote an old English proverb, "A man who cannot abide a bad market deserves
not a good one." For most people, enduring the ebbs and flows of the market
requires a sound investment strategy that involves asset allocation linked to
time horizon and risk tolerance.

At John Hancock, we employ sound strategies of our own. In recent years, we have
been pursuing several innovative business initiatives. These initiatives involve
expanding John Hancock's retail marketing efforts through traditional and
alternative distribution channels while building on two of the company's core
competencies -- insurance and investments.

Established 135 years ago, John Hancock is widely recognized as one of the
nation's leading providers of variable life insurance and annuity products. More
recently, the company has established a solid infrastructure and growing
reputation in the investment industry. John Hancock and its subsidiaries offer a
wide variety of fixed-income, equity, and international investments, with more
than $100 billion in assets under management.

As the primary investment advisor for the Variable Series Trust, John Hancock
has created an investment structure featuring 18 unique fund choices managed by
leading retail and institutional money managers. Before selecting managers for
each portfolio, John Hancock engaged in a careful screening process, identifying
managers with demonstrated skill in delivering superior investment returns
(relative to appropriate benchmarks), exercising investment discipline (sticking
to the objective), and employing effective risk control. On behalf of our
customers, John Hancock monitors the performance and compliance of each
portfolio to ensure that these investments live up to expectations.

                                In the years to come, we hope to expand our
                                relationship with you when it comes to insurance
[PICTURE OF HENRY D. SHAW,      for the unexpected and investments for the
  CHAIRMAN APPEARS HERE]        opportunities. And so, while the investment
                                climate is ever-changing, one thing remains
                                constant: John Hancock's commitment to
                                delivering value through quality products and
                                responsive service. As always, your John Hancock
                                registered representative is available to
                                personally assist you in these important
                                matters.


Sincerely,

 ECONOMIC OVERVIEW: MID-YEAR REVIEW 1997
 JOHN HANCOCK ECONOMIC RESEARCH
 
After picking up speed to over 3% during 1996, the US economy was expected to
slow in early 1997. Instead, the pace of growth accelerated to 6% in the first
quarter before dropping back in the second. Even with a slower second half,
consistent with consensus forecasts, growth for the year as a whole is likely
to exceed 3% once again.
 
The long-run capacity of the economy is generally estimated to be increasing at
2-2.5% per year, and continued above-trend growth in 1997 has therefore reduced
unused capacity--both capital and labor. In particular, the unemployment rate
has declined from the already low 5.4% rate of 1996 to 5% by mid-1997. This was
expected to raise inflationary pressures, which have historically followed
whenever the unemployment rate fell below 5.5-6%. Instead, inflation actually
declined in the first half of 1997.
 
With little inflation and job growth at a rate of 2-3 million net new jobs per
year, it is not surprising that consumer confidence measures rose to new
records during 1997. Despite high levels of consumer debt (and high rates of
personal bankruptcy and defaults), the momentum of job growth, income growth
and consumer spending has continued to sustain the expansion. This is already
the third longest economic upswing in US history, and there are no obvious
imbalances that would derail it before it sets the all-time record in the year
2000.
 
The Federal Reserve raised short-term rates in March, 1997, responding to
excessive growth which it feared might spark inflation. Signs of moderation in
the second quarter made additional increases unnecessary, spurring further
advances in financial markets. The Fed, and most analysts, expect an economic
slowdown, but are concerned that this may puncture the mood of optimism that
supports current asset prices.
 
The combination of above-trend real growth, low unemployment and minimal
inflation has seemed the best of all possible worlds for financial markets.
Concern about the response of the Federal Reserve to falling unemployment
caused some volatility early in 1997, but both long and short-term interest
rates had reversed earlier increases by mid-year. Optimistic valuations in
equity markets were thus supported by low interest rates and by rising
corporate earnings, which were fuelled by declining interest costs, higher
overseas earnings, and a drive for greater efficiency.
 
Among major US trading partners, Japan's growth was disappointing in early
1997, while Canada and western Europe started to recover from their weak
performance in 1996. Mexico, rebounding from its recent crisis, grew faster
than expected in 1996, and this trend is continuing so far in 1997.
 
Overall, growth in most of the developed world will continue to be slower than
in the emerging markets of Asia and Latin America. These countries are growing
two to three times faster than the US, and are now major players in the world
economy. Despite recent currency volatility, more than twice as much of the
world's economic growth is expected to take place in Asia as in all of North
America during the next 5-10 years. A significant component of earnings at
major US corporations is now coming from Asian operations, and this trend will
undoubtedly continue.

 MONEY MARKET PORTFOLIO
 JOHN HANCOCK                                               PETER MITSOPOULOS
 After more than a year of holding the Fed Funds target rate steady, the
Federal Reserve increased the rate 25 basis points to 5.50%. The initial
reaction to this move was muted as money fund managers felt they could finally
see a direction in Fed policy. Except for brief periods prior to the move, the
short end of the yield curve (30 days to 90 days) remained relatively flat.
With no evidence of a possible decrease in the Fed Funds rate and only
speculation of when an increase would next occur, it clearly made no sense to
extend maturities without a corresponding pickup in yield. The Portfolio's
average maturity was virtually unchanged at 37 days at the end of March versus
36 days at the end of December.
 As the second quarter began (and the Fed's next meeting scheduled for May),
bearish sentiment surfaced almost immediately and the money market curve
steepened. The interest rate spread between 30 day and 90 day investments
widened and reached a high of around 13 basis points by the end of April. We
began extending maturities in April, picking up yield as the curve steepened.
By the end of the quarter the Portfolio had reached an average maturity of 46
days.
 Except for the persistently low unemployment rate and tight labor markets,
economic indicators were not exhibiting the signs of inflation critical for
what was a widely expected further tightening at the May meeting. The May
meeting passed with no action. And, with no meeting scheduled in June,
investor sentiment reversed direction and the yield curve flattened to a near
zero spread by the end of the quarter.

 SHORT-TERM U.S. GOVERNMENT PORTFOLIO INDEPENDENCE INVESTMENT ASSOCIATES,
 INC.                                                              TOM SPICER
 During the second quarter, interest rates fell moderately, allowing the
Portfolio to show a positive absolute performance. Year-to-date, the Short Term
Government Portfolio has mirrored it's benchmark (the Merrill Lynch 1-5 Yr
Government Index) with a net return of 2.62% versus 2.64%.
 Many investors grew increasingly weary of the rising equity markets and
decided a correction was not far away, transferring assets into funds not
unlike this one. The Portfolio was kept fully invested and inflows were used to
rebalance the Portfolio as needed, minimizing transaction fees. The Portfolio's
strategic over-exposure in the Agency sector has been a major contributor to
performance. At quarter-end the fund had 65% in Agencies versus 18% for the
benchmark. These securities are an excellent source of additional yield and
also provide exposure to a sector which has historically outperformed the
Treasury market on a total return basis. This over-weighting decision relates
directly to our philosophy of seeking cheap, predictable cashflows. That is, we
believe Agency paper offers incremental yield without much additional risk as
to the certainty of payment and therefore an attractive risk/return
relationship.
 Looking forward, we expect the interest rate environment to be more subdued
and somewhat range-bound. The Fed will most likely be on hold for the coming
months, closely watching the economic indicators as they are released. As far
as portfolio strategy is concerned, we expect to maintain a relatively over-
weighted position in the Agency sector and, given the conservative nature of
the fund, overall interest rate risk will be kept to minimum.

 SOVEREIGN BOND PORTFOLIO JOHN HANCOCK ADVISERS, INC.                  JIM HO
 For the six months ended June 30, 1997, Sovereign Bond Portfolio returned
3.62% versus 2.74% for the Lehman Brothers Government/Corporate Bond Index.
During this period, interest rates vacillated within a modest trading range,
while corporate bond spreads narrowed and widened several times relative to
Treasuries.
 No major changes were made to affect duration, though the Portfolio took
advantage of the spread widening to add to positions in Yankee and emerging
market credits. As investor confidence returned, rates declined and spreads
compressed again, improving Portfolio results via price appreciation.
 Investment in Project Finance Notes also contributed to the Portfolio's
performance, as these issues were purchased at extremely attractive yields, due
in part to their newness and perceived credit complexity. Spreads tightened
promptly as market participants later identified their inherent value,
particularly as good quality, higher yielding paper remained in demand. Also,
the Portfolio's holdings of Owens Illinois 11s and Stone Consolidated 10 1/4s,
purchased at spreads of 250 basis points over Treasuries, were tendered during
the second quarter at 50 basis points over Treasuries, resulting in handsome
gains.
 Looking ahead, we remain optimistic regarding on the bond market over the long
term. Though our strategy is not top down driven, we believe a short run risk
to the bond market entails additional proactive tightening by the Fed before
year-end to slow continued strong demand growth in the economy to a non-
inflationary pace. Therefore, we are likely to maintain a slightly shorter
duration versus the Index, and be inclined to sell Treasuries to selectively
add to late cyclical corporate credits (paper, media, cable) which have
performed well during the latter stages of an economic cycle.

                                                       INCEPTION: MAY 1, 1996
 STRATEGIC BOND PORTFOLIO J.P. MORGAN INVESTMENT MANAGEMENT, INC.       CHRIS
 DURBIN & LILI DUNG
 During the first half of 1997, the Portfolio was slightly underweight U.S.
relative to the foreign markets due mainly to the outlook for U.S. interest
rates. Although inflation in the U.S. remains well contained, we believe
underlying economic strength may start upward inflationary pressure.
 Year-to-date, the Portfolio slightly lagged the index net of fees. Within the
domestic portion, our investment philosophy of underweighting Treasuries to
invest in the yield-advantaged corporates and mortgages as well as high yield
and emerging markets securities contributed positively to performance. The
Portfolio maintained a weighting close to the maximum exposure (10%) to high
yield and emerging markets.
 Within the North American bloc, the short position in the U.S. was mostly
offset by long positions in Canada and Australia. This positively impacted the
Portfolio as these markets outperformed the U.S. during the first half of the
year. Within Europe, the Portfolio favored the higher yielding markets of
Sweden and the U.K. Within Japan, the Portfolio maintained an underweight
position--which detracted from the Portfolio in the first quarter as Japan was
the best performing major bond market and contributed in the second quarter as
Japan shifted to be the worst performer.
 Looking forward, we expect to maintain a short position in the U.S., given the
current level of interest rates and expectations for stronger growth. We
continue to favor Canada but will watch this position carefully as the Bank of
Canada has moved to a tightening stance. Within Europe, we continue to favor
the higher-yielding markets and the U.K., as this country is more likely to
meet all of the Maastricht economic criteria than Germany. Within Japan, we
will continue to remain close to neutral as we do not anticipate a rise in
official rates until we see stronger monetary conditions.

 MANAGED PORTFOLIO INDEPENDENCE INVESTMENT ASSOCIATES, INC.   JOHN FORCELLI &
 TOM SPENCER
 Overall, the equity portion of the Portfolio generated about an 18.2% (gross
return) for the first half of 1997. The fixed income portion increased about
2.6% (gross return) for the first half of 1997 which was in line with the
benchmark fixed income portfolio. Net performance on the overall Managed
Portfolio year-to-date is 8.90%, underperforming the benchmark.
 In 1997, the market rallied as investors realized that the economy was not
overheating and the Federal Reserve was not likely to raise short term rates
any time soon. Within the equity portfolio, healthcare stocks were among the
best performing sectors in the portfolio with stocks such as Warner Lambert,
HealthSouth and Johnson & Johnson performing particularly well. Financial
stocks such as March & McLennan, Bank America and Cigna also did well. Selected
technology stocks such as Computer Associates and Compaq Computer were also
strong performers. The fixed income market appears ready to continue to rally
over the coming months based on the benign inflation outlook. The bond portion
of the Portfolio has an overweighting in corporates and mortgages. The quality
of the fixed income securities is high with an overweighting in three to ten
year maturities.
 We continue to believe that the economy in the U.S. will grow moderately for
the balance of 1997 and into 1998. However, we continue to believe that the
financial markets will remain volatile during the next six to twelve months and
we believe that portfolio risk control in a slowing economy is of the utmost
importance.

 GROWTH & INCOME PORTFOLIOINDEPENDENCE INVESTMENT ASSOCIATES, INC.    PAUL F.
 MCMANUS

 The stock market resumed its powerful advance on the second quarter with a
total return of 17.4%, delivering a first half gain of 20.5%. We have been in
an ideal environment for stocks as the economy is growing steadily, inflation
and interest rates are stable and companies are increasingly focused on
shareholder value. The stock market returns over the past three years have been
extraordinary, as the annualized return has been close to 30%. Given the
narrow, concentrated advance by large capitalization stocks, the average
manager is well behind the market.
 During the last three months, the "mega-cap" stocks continued to outperform so
that for the first half of 1997 these 50 largest stocks within the S&P 500
returned 23.7% while the remaining 450 returned only 17.0%. Because these
issues are trading at such relatively high P/E multiples, our valuation model,
which focuses on owning stocks which are undervalued, has not found them
attractive. This phenomenon, although cyclical, could persist. But, ultimately,
we know that proper valuation forces will come back into play.
 At the end of June, the Portfolio owned 116 stocks and was fully invested with
a cash position of 2.0%. The Portfolio maintains market-like risk
characteristics and conforms to the benchmark guidelines specific to your
Portfolio. The best performers in the Portfolio were Warner Lambert, Home
Depot, and Marsh McLennan. Laggards included GTE as the telecommunications
industry is going through deregulation and Electronic Data Systems, which had
some disappointing earnings results. The Portfolio's P/E is well below the S&P
500's 20.6x multiple, another indicator that there are many attractively-valued
stocks outside of the current market favorites. We would, as a matter of
course, expect a 5-10% correction anytime, but if the current environment
persists, financial market returns still look attractive.

 LARGE CAP VALUE PORTFOLIO T. ROWE PRICE ASSOCIATES, INC.        BRIAN ROGERS

 What's a conservative value oriented fund to do in a market environment like
the first half of 1997? Our strategy has been to focus on risk more than usual.
We reduced our investments in a number of companies which have performed well
and which, consequently, no longer appear as undervalued as they once did.
Several of our larger sales represent investments in some of the world's great
companies (Warner Lambert, Honeywell, General Electric). When the market fully
values a company's equity, however, our valuation discipline prompts us to
recycle these holdings into more reasonably valued companies with attractive
upside potential and relative low downside risk.
 In looking at large purchases, these companies share the characteristics of
attractive relative valuations, high relative dividend yields, and in our
opinion good upside potential and moderate downside risk. We added to positions
in fine companies such as Dow Chemical, Knight-Ridder, GM and Duke Energy.
 Coming into 1997 we began to see a delinkage occurring, as stock prices have
surged at a much faster rate than have corporate earnings and dividends. This
delinkage is even more true today after the market's strong advance. We will
continue to follow our conservative investment approach because there are
always interesting investment opportunities in any market environment. From an
expectations standpoint, however, we believe that the going is likely to get
tougher sometime between now and the end of the year.

 LARGE CAP GROWTH PORTFOLIO
 INDEPENDENCE INVESTMENT ASSOCIATES, INC.            MICHAEL G. TROTSKY

 The Large Cap Growth Portfolio closely resembles the Frank Russell 1000 Growth
Index benchmark in terms of expected returns, risk, and volatility of returns.
The Large Cap Growth Portfolio slightly underperformed its benchmark for the
second quarter. For the year, the Large Cap Growth Portfolio has returned
17.99% versus the FR 1000 Growth Index return of 19.55%.
 The best performing stocks for the quarter included technology issues such as
Microsoft, Computer Associates, Compaq, and Dell Computer; healthcare stocks
like Warner-Lambert, Merck, and Schering Plough; and classic large cap growth
stocks like General Electric and Home Depot. Major holdings going forward
include Microsoft, Intel, Johnson & Johnson, Merck, and General Electric. All
of these companies are currently exhibiting "cheapness and improving
fundamentals".
 Simply put, the United States is in a state of economic nirvana. Consumer
confidence is at a 28-year high, unemployment is at a 23-year low, and
inflation is at a 32-year low with no cost pressures on the horizon. Despite
the first quarter's scorching 5.9% GDP growth, the Federal Reserve Board
declined to raise interest rates at both its May 20th and July 2nd policy
meetings. Recent economic data (particularly weak retail sales and a buildup in
inventories) indicate that second quarter economic growth slowed to
approximately 2%. We believe that the economy will reaccelerate moderately
during the remainder of 1997 as many of the driving forces behind its advance
remain in place: an optimistic consumer, strong industrial output and capacity
growth, increases in productivity, dormant inflation, and consistent economic
and monetary policy. Financial markets should remain volatile during the next
six to twelve months making portfolio risk control of the utmost importance.

Mid Cap Value                                            INCEPTION: MAY 1, 1996
NEUBERGER & BERMAN, LLC                                M. Kassen & R. Gendelman

 On May 1, 1997 State Street Global Advisors began managing the Equity Index
Portfolio. The performance for the period May 1, 1997 through June 30, 1997 was
10.61% vs. the S&P 500 Index return of 10.84%. The variance can primarily be
attributed to the initial transition period where the Portfolio's composition
changed to a fully replicated portfolio that includes all 500 stocks in the S&P
500 Index.
 The S&P 500 continued to provide exceptional returns in the first half of
1997. The index provided a total return of 20.50% for the six month period
ending June 30--outperforming all of the other major market indices in the
first half of 1997. The first half S&P 500 return follows the 1996 return of
22.96% and 1995's incredible 37.58%. Investors tracking the S&P 500 have more
than doubled their money in the last 30 months.
 There have been tremendous net inflows to stock funds this year. Index funds
have been a big recipient of those inflows because of their current popularity
with investors. The phenomenal returns of the S&P 500 have made it difficult
for active managers to outperform the index over the last 30 months.
 The mega-capitalization stocks, such as General Electric, Coca Cola, Exxon and
Microsoft are dominating the S&P 500. The ten largest companies in the S&P now
compose nearly 20% on the index. The twenty largest names compose almost 30% of
the index.

 REAL ESTATE EQUITY PORTFOLIO INDEPENDENCE INVESTMENT ASSOCIATES, INC. DALTON
 AVERY

 The strong performance that REITs showed in 1996 had two negative effects on
their performance in the first half of '97. First, valuations of REITs were
high relative to their historical averages which caused some correction in the
stocks. Second, higher prices for REIT stocks encouraged heavy new equity
issuance. In the first half REITs raised $12 billion in new equity or more than
20% of all equity capital raised by U.S. stocks in the period. This more than
offset the flow of new money into REIT funds in the same period and further
reduced demand for other REIT stocks.
 Some improvement occurred in June as REITs outperformed the broader stock
averages for the first time in '97. The performance of REITs in the first half
is not unlike their performance in first half '96. Valuation levels are again
attractive as average REIT earnings have increased 9-10%. The positive total
return for REITs in the first half was entirely supported by the 6% average
yield.
 In the first half the best performing REIT property sectors were manufactured
home communities, community shopping centers and hotels. The weakest sectors
were office property REITs and industrial properties (warehouse and
distribution). The office and industrial sectors were the strongest performers
at the end of 1996 so a correction was not unexpected. This sector also saw a
disproportionate amount of new equity issuance. These sectors also showed the
strongest earnings gains in the period so valuations are again reasonable.
 The Real Estate Equity Portfolio outperformed its benchmark in the second
quarter although the Portfolio did slightly trail the benchmark for the full
first half by 100 basis points. The trend against the benchmark has been
favorable for three months and we believe that the Portfolio is well structured
to take advantage of an improved second half performance for the REIT group.

 MID CAP VALUE                                            INCEPTION: MAY 1, 1996
 NEUBERGER & BERMAN, LLC                                M. KASSEN & R. GENDELMAN

 The second quarter displayed the strongest performance by the broad market
averages in over a decade, paced by large-capitalization stocks. Strong
corporate earnings reports and a benign inflation outlook captivated investors,
who generally ignored valuation levels that we believe are stretched. In this
environment, the Mid Cap Value Portfolio continued to outperform its benchmark
(net of fees) with a return of 13.05% vs. the Russell Mid Cap value index
12.60% return.
 Since the beginning of the year, the Portfolio has added over 145 basis points
net of fees and expenses versus the Russell Mid Cap Value Index. Year-to-date
the Mid Cap Portfolio's rate of return, net of fees, and expenses is 15.54%
which outpaced the Russell Mid Cap Value Index return of 14.51%.
 Although it is harder to find values in 1997's heady environment, we believe
that the amazing strength of large-cap stocks relative to the rest of the
market has made the mid-cap world a relatively attractive sector to prospect
for new ideas. We hope to take advantage of market turbulence to enhance the
quality and potential of our Portfolio.
 It is our belief that, over time, other investors will come to acknowledge the
worth of the undervalued securities we purchased, causing these securities to
appreciate. But even if this does not occur, we feel that the Portfolio's
downside risk will be reduced because the underlying companies were carefully
selected and the securities were bought at discounted price levels.

 MID CAP GROWTHJANUS CAPITAL CORPORATION                             JIM GOFF

 After a solid performance in 1996, equities built on their previous gains and
quickly climbed to new records. However, fear of an overheated economy along
with a Federal Reserve rate increase combined to stir up stocks late in the
first quarter, and volatility reemerged. Following the market's rebound late
in April, large stocks proceeded quickly to new records, while the small- and
mid-sized indices struggled to regain records set in January. The month of May
saw a reversal in investor focus, and small- and mid-sized stocks outperformed
their larger counterparts by a wide margin. In June, however, large caps once
again reasserted themselves.
 During the period, I remained true to my investment discipline, and my
patience began to pay off. We had a number of stocks that gained over 35%,
including Fastenal, Papa John's, Premier Parks, Omnicare, and the Apollo
Group. The fundamentals of these companies did not change during the period.
Rather, the turnaround in market psychology once again rewarded companies with
solid fundamentals and rapid earnings growth.
 Our research efforts continued to generate new investment ideas, and we added
positions in the media industry during the quarter, including: Clear Channel
Communication, Evergreen Media, Outdoor Systems, Heftel Advertising, and
Univision. All five companies operate in highly defined market segments,
ranging from television and radio broadcasting to outdoor advertising. Each
has a strong management team that is growing their respective businesses both
internally and through acquisition. Additionally, all five are generating
strong cash flows while operating in areas that have low capital needs.

 SPECIAL OPPORTUNITIES PORTFOLIO 
 JOHN HANCOCK ADVISERS, INC.                                    MANAGEMENT TEAM
 For the six months ended June 30, 1997, Special Opportunities returned (6.21)%
versus a 10.54% return for the Russell Mid Cap Growth Index.
 During the second quarter we made significant progress towards positioning the
Portfolio to benefit from our top-down analysis. The underpinning driving our
long-term macroeconomic views is strong economic growth continuing to fuel
corporate profits, within a low inflation, low interest rate environment. We
have overweighted sectors which will benefit most from these trends.
 We took advantage of the April sell off in Financial stocks to build a
position in several quality insurance and banking companies which will benefit
from the low interest rate environment, the strong economy, and the industry-
wide consolidation trend. Capital goods companies will also benefit from the
strong economy. By focusing their capital resources on profitable segments,
they have transformed themselves into secular growth companies.
 Our economic outlook has moved us away from those sectors which will
underperform under these conditions. Since precious metals commodity prices
perform poorly in low inflation environments, prospects for these companies
turned bleak. Even with heavy investments in new mining technologies, our
holdings would not be able to withstand low commodity prices without a negative
effect on their bottom lines.
 A similar scenario exists for energy companies. Weaker oil prices led to poor
prospects for exploration and production companies. Therefore, we moved from
these companies to the oil service providers, which are less susceptible to
lower commodity prices.

 SMALL CAP VALUE PORTFOLIO INVESCO MANAGEMENT & RESEARCH    STEVE KASZYNSKI &
 BOB SLOTPOLE

 The John Hancock Small Cap Value Portfolio advanced 18.3% for the second
quarter. This compares favorably to the 16.2% rise of the Russell 2000 Small
Cap Index. The results were particularly impressive considering our 15%
underweight in technology which was the best performing sector for the
quarter. The good relative return for the quarter was largely attributable to
our stock selection criteria, which favors higher quality companies with
reasonable valuations versus their peers. The portfolio is extremely well
diversified and its sector weights are controlled to prevent overweights in
sectors where valuations are getting ahead of themselves. The spectacular rise
of technology stocks in recent years is a good example of this. Over time,
small stock investors have been drawn to technology as a moth to a flame,
irrespective of the extreme valuations in this market sector.
 Our search for value takes place in all corners of the small company universe
and includes holdings like Lands' End, Inc., Dexter Corporation and Zeigler
Coal Holding Company. These are solid companies with good franchises, but are
rarely targeted by investors chasing high growth.
 We are content to own companies in which management owns a significant stake,
the use of debt reflects the riskiness of the business, and where management
has a clearly articulated business strategy. In this way, we hope to deliver
consistency as well as the above average returns that smaller companies have
historically generated.

 SMALL CAP GROWTH PORTFOLIO                               INCEPTION: MAY 1, 1996
 JOHN HANCOCK ADVISERS, INC.                                       BERNICE BEHAR
 For the six months ended June 30, 1997, Small Cap Growth Portfolio returned
5.66% versus a 5.23% return for the Russell 2000 Growth Index.
 We continue to favor the Capital Goods and Basic Materials arena, as the
companies within these sectors are leveraged to the economy and should continue
to benefit from the latter stages of an economic expansion. Lone Star
Technologies and Maverick Tube are two examples who have experienced strong
earnings growth and correspondingly strong share prices.
 The Consumer Cyclicals sector we continue to overweight for similar reasons,
and we favor the stocks of Central Newspapers and Universal Outdoor. Central
Newspapers publishes newspapers in the Indianapolis and Phoenix markets, and
has been experiencing strong revenue growth from its classified and help wanted
businesses. Universal Outdoor is a midwest operator of billboards and has
witnessed similarly strong demand.
 Technology is another area we favor and we put a lot of cash to work in this
sector during the second quarter. Although this sector can be extremely
volatile, we continue to find names with excellent growth prospects, and we
like the small semiconductor equipment makers in particular. Semtech Corp. is
an example, and should benefit from Intel's conversion to the Pentium II chip.
Another name with exciting prospects is Information Management Resources which
has developed a cost effective way of handling the Year 2000 problem by e-
mailing code to engineers in India at a fraction of the cost of hiring U.S.
based engineers.
 Although small cap stocks continue to underperform their large cap brethren,
we remain optimistic. Small cap growth stocks reported their best performance
this past quarter since 1991. And with small cap valuations at seven year lows
relative to the S&P 500, we foresee significant upside potential in small caps
going forward.

 INTERNATIONAL BALANCED PORTFOLIO BRINSON PARTNERS, INC.      MANAGEMENT TEAM

 Within the equity portion of the Portfolio year-to-date, security selection
contributed to Portfolio returns, while market allocation detracted slightly
from performance. Within international bonds, market allocation made a
meaningful contribution to Portfolio performance. Currency allocation added
value over this time frame as well. The most significant contribution came from
our overweight in the U.S. dollar and underweight in the Continental European
currencies in the first half of 1997.
 Year-to-date, international equity markets returned 17.76% on a dollar hedged
basis. European markets gained 25.49%, while the Pacific region rose a more
modest 8.41%. Over this same time frame, international bonds rose 4.65% in
dollar-hedged terms. Returns during this period were fairly tightly clustered
across the 16 international bond markets, reflecting a macroeconomic
environment with few large surprises and converging expectations on inflation
and interest rates. The majority of non-U.S. economies have been categorized by
subdued economic growth and price inflation, and by efforts to cut government
budget deficits. Currencies declined an average of 5.37% relative to the U.S.
dollar, with most of the depreciation occurring in the European currencies.
 Our view remains that, with few exceptions, international equity markets are
overpriced. Given our valuation and fundamental analysis, international bonds
remain attractive on both an absolute and relative basis. Recent events in
Europe have magnified the tensions within the European Union, leading us to
reduce our broad overweight in continental European equity markets in favor of
southeast Asia. The Portfolio continues to have no exposure to the Japanese
bond market, where yields remain substantially below our estimates of fair
value. We continue to find attractive valuations within Germany, Canada,
Denmark, Australia and the U.K. We recently lowered our duration strategy to
neutral in Australia, Canada, and Sweden.

INTERNATIONAL EQUITIES PORTFOLIO                          INCEPTION: MAY 2, 1988

 For the six months ending June 30, 1997, International Equities returned
11.18% (net) versus a return of 11.36% for the MSCI EAFE Index. Many overseas
markets in both the developed world and emerging world, with the exception of
emerging Asia, produced solid results over the last six months.
 Since year end, we have reduced our positions in Japan and Hong Kong, however
they remain our two largest country holdings. Both markets lagged in the first
quarter, Japan due to continued economic woes, banking problems and government
tax increases, and Hong Kong in response to rising U.S. interest rates and
fears about the imminent transition to Chinese rule. Confidence, however,
returned to these markets in the second quarter. The easing of Japan's monetary
policy and the yen's weakness provided encouragement for resumption of growth
to 2--2.5%. In Hong Kong, transition concerns dissipated and investors became
encouraged about the longer-term for both Hong Kong and its impact on China.
 The Portfolio benefited from our establishing a significant position in the
emerging markets of Latin America. Many of these countries have embraced
economic reform and, unleashing significant investment opportunities. Brazil,
our largest country holding in Latin America, has seen its stock market soar
this year as the positive combination of political stability, privatization and
economic reform plays out.
 Our strategy in Europe is focused on corporate restructuring stories. The
increased private and public sector discipline associated with the process of
monetary union is presenting some very attractive investment opportunities. The
U.K. remains our largest position in Europe.

 INC.                                                             MARTIN WADE

 The total return performance for the first six months of 1997 for The
International Opportunities Portfolio was roughly in line with the 11.36%
return of the MSCI EAFE Index.
 Country allocation relative to the EAFE Index provided value-added over the
first six months of 1997, with overweightings in the Netherlands and Latin
America as well as the underweighting of Japan the most notable contributors.
Stock selection relative to the index was a small positive factor, with the
most significant contributions coming from portfolio holdings in Brazil and
Japan.
 We continue to have no currency hedges in place in your Portfolio. That said,
our underweight yen position relative to the benchmark subtracted value as that
currency moved higher versus the U.S. dollar during the second quarter.
 Looking forward, we continue to find the general economic outlook healthy--
with growth now accelerating in Continental Europe and better than we had
expected in Japan. Importantly, this improved level of economic activity has
not led to higher rates of inflation--a backdrop which has helped to underpin
bond markets worldwide. The current environment should continue to provide
reasonable support to global equities.
 Recent market strength has taken stock market valuations in a number of
regions to relatively expensive levels, but unless bond markets weaken or
corporate earnings disappoint, we believe that these valuations can be
sustained given the low inflation environment worldwide. Corporate earnings
look most vulnerable in the U.K. and, to a lesser extent, Japan, which helps to
explain our continued underweighting of these markets. Generally, though,
corporate earnings look set to come through strongly in 1997, and this should
help to underpin a reasonable outlook for international equities through the
balance of the calendar year.

</TABLE> 

During the first half of 1997 investors in large cap stocks continued to be
handsomely rewarded as the S&P 500 continued to set new record highs. Small Cap
stocks finally made a recovery in the 2nd Quarter after a long period of
relatively weak performance. Bond investors fared well due to expectations of
low inflation, the pace of the economy, and the Federal Reserve's view that
inflation is under control in the short-term. International stocks performed
well, turning in their best quarterly performance, during the 2nd quarter,
since the 4th quarter of 1988. Emerging markets in Latin America performed very
well compared to the Far East Asian markets. The largest 50 stocks in the
market returned 23.69%, outpacing the S&P 500 by over 300 basis points thus
providing a good measure of the narrow breadth of the market. The international
markets performed very well during the first-half of the year, almost all of
this performance occurring during the 2nd quarter due to strong performance in
European markets, Japan, and Hong Kong. Emerging markets returned 17.75% as
measured by the MSCI Emerging Markets Free index. Latin American markets
returned 40.79% outperforming the smaller Far East Asian markets which returned
- -1.64%.

During the 2nd quarter, fixed income markets benefited by moderating economic
growth and indications of low inflation. Given this environment, interest rates
declined providing bond investors with solid returns.

NOTES TO FINANCIAL STATEMENTS
JOHN HANCOCK VARIABLE SERIES TRUST I
June 30, 1997 (Unaudited)
- -------------------------------------------------------------------------------
(000's Omitted)
NOTE A--ORGANIZATION
 
  The John Hancock Variable Series Trust I (the "Fund") is a diversified open-
end management investment company registered under the Investment Company Act
of 1940, as amended. The Fund is organized as a Massachusetts business trust.
The Fund consists of eighteen portfolios: Large Cap Growth, Sovereign Bond,
International Equity, Small Cap Growth, International Balanced, Mid Cap
Growth, Large Cap Value, Money Market, Mid Cap Value, Special Opportunities,
Real Estate Equity, Growth & Income, Managed, Short-Term U.S. Government,
Small Cap Value, International Opportunities, Equity Index, and Strategic
Bond. The Fund may add or delete portfolios in the future to accommodate
various investment objectives. The Fund has issued shares of beneficial
interest exclusively to John Hancock Variable Life Account U ("JHVLAU"), John
Hancock Variable Life Account V ("JHVLAV"), John Hancock Variable Life Account
S ("JHVLAS"), and John Hancock Variable Annuity Account I ("JHVAAI") to fund
policies and contracts issued by the John Hancock Variable Life Insurance
Company ("JHVLICO"), and to John Hancock Variable Annuity Account U
("JHVAAU"), John Hancock Variable Annuity Account V ("JHVAAV"), and John
Hancock Mutual Variable Life Insurance Account UV ("JHMVLAUV") to fund
contracts and policies issued by John Hancock Mutual Life Insurance Company
("John Hancock").
 
NOTE B--ACCOUNTING POLICIES
 
  Estimates: 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.
 
  Valuation of Investments: For the Large Cap Growth, Small Cap Growth, Mid
Cap Growth, Large Cap Value, Mid Cap Value, Special Opportunities, Real Estate
Equity, Growth & Income, Managed, Small Cap Value, and Equity Index
Portfolios: Common stocks traded on national securities exchanges are normally
valued on the basis of closing prices. Securities traded in the over-the-
counter market and securities with no sales on the day of valuation are
normally valued at their last available bid price.
 
  For the Sovereign Bond, Managed, Short-Term U.S. Government, and Strategic
Bond Portfolios: Debt investment securities having a primary market over-the-
counter are valued on the basis of valuations furnished by a pricing service
which determines valuations for normal institutional size trading units of
debt securities, without exclusive reliance upon quoted prices.
 
  For the Money Market Portfolio: The Board of Trustees has determined that
the appropriate method for valuing Portfolio securities is amortized cost, so
long as the average weighted maturity of money market instruments comprising
the Portfolio does not exceed 90 days. Accordingly, Portfolio securities are
valued at amortized cost which approximates market value. The amortized cost
method involves valuing a security at its cost on the date of purchase and
thereafter assuming a constant amortization to maturity of the difference
between the principal amount due at maturity and the cost of the security to
the Portfolio.
 
  For each of the Portfolios, short-term investments, with a maturity not to
exceed 60 days, are valued at amortized cost which approximates market value.
 
  For the International Portfolios: Investments in securities traded on
national securities exchanges in the United States or on equivalent foreign
exchanges are normally valued at the last quoted sales price on such exchanges
as of the close of business on the date of which assets are valued. Securities
traded in the

over-the-counter market and securities traded with no sales on the day of
valuation are normally valued at their last available bid price. All Portfolio
securities initially expressed in terms of foreign currencies have been
translated into U.S. dollars as described in "Currency Translation."
 
  Investment securities for which no current market quotations are readily
available, including certain foreign securities, when held by the Portfolios,
are valued at fair value as determined in good faith by the Board of Trustees.
 
  Investment security transactions are recorded on the date of purchase or
sale. Dividend income is recorded on the ex-dividend date and interest income
is recorded on the accrual basis. Dividend income for the Large Cap Growth,
International Equities, International Balanced, Mid Cap Growth, Large Cap
Value, Mid Cap Value, Special Opportunities, Growth & Income, Managed,
International Opportunities, Equity Index and Strategic Bond Portfolios are
shown net of foreign taxes withheld of $15, $204, $33, $1, $5, $1, $10, $132,
$57, $30, $2, and $7, respectively. Realized gains and losses from security
transactions are determined on the basis of identified cost.
 
  Repurchase Agreements: The Portfolios of the Fund may enter into repurchase
agreements which are contracts under which a Portfolio would acquire a
security for a relatively short period (usually not more than 7 days) subject
to the obligation of the seller to repurchase and the Portfolio to resell such
security at a fixed time and price (representing the Portfolio's cost plus
interest). A Portfolio will enter into repurchase agreements only with member
banks of the Federal Reserve System and with "primary dealers" in United
States government securities. The underlying securities, which represent the
collateral of the agreement, must be marked to market daily to ensure that
each repurchase agreement is fully collateralized at all times. A Portfolio
will not invest more than 10% of its net assets in repurchase agreements
maturing in more than 7 days.
 
  Joint Repurchase Agreements: The Small Cap Growth, International Equities
and Special Opportunities Portfolios of the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Sub-Adviser"), an indirect wholly-owned subsidiary of John Hancock,
may participate in a joint repurchase agreement pursuant to an exemptive order
issued by the Securities and Exchange Commission. Aggregate cash balances are
invested in one or more repurchase agreements, whose underlying securities are
obligations of the U.S. Government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint account on
the Fund's behalf. The Sub-Adviser is responsible for ensuring that the
agreement is fully collateralized at all times.

  Joint Trading Account: Pursuant to an Exemptive Order issued by the
Securities and Exchange Commission, the order permits the existing Portfolios
of the Fund to pool daily uninvested cash balances, together with the balances
of any future Portfolios of the Fund, into a joint account for the purpose of
investing the cash balances in short-term repurchase agreements, commercial
paper and other short-term investments which in no event will have a maturity
in excess of seven days. Joint Account holdings as of June 30, 1997:

Portfolios may buy and sell financial futures contracts to hedge against the
effects of fluctuations in interest rates and other market conditions. At the
time a Portfolio enters into a financial futures contract, it will be required
to deposit with its custodian a specified amount of cash or U.S. government
securities, known as "initial margin." Each day, the futures contract is
valued at the official settlement price of the board of trade or U.S.
commodities exchange. Daily variation margin adjustments, arising from this
"mark to market," are recorded by the Portfolios as unrealized gains or
losses.
 
  When the contracts are closed, the Portfolio recognizes a gain or a loss.
Risk of entering into futures contracts include the possibility that there may
be an illiquid and/or that a change in the value of the contract may not
correlate with changes in the value of the underlying securities. In addition,

  Forward Foreign Currency Contracts: The Fund may use foreign currency
contracts to facilitate transactions in foreign securities and to manage the
Portfolio's currency exposure. Contracts to buy generally are used to acquire
exposure to foreign currencies, while contracts to sell are used to hedge the
Portfolio's investments against currency fluctuations. Neither type of foreign
currency transaction will eliminate fluctuations in the prices of the
Portfolio's securities or prevent loss if the price of such securities should
decline. The U.S. dollar value of a forward foreign currency contract is
determined using forward exchange rates supplied by a quotation service.
Purchases and sales of forward foreign currency contracts realized gain (loss)
is recognized on settlement date.
 
  Currency Translation: For the International Portfolios: all assets or
liabilities initially expressed in terms of foreign currencies are translated
into U.S. dollars based on London currency exchange quotations as of 5:00
p.m., London time, on the date of any determination of the net asset value of
the Fund. Unrealized exchange adjustments are included in unrealized
appreciation (depreciation) of investments. Transactions affecting statement
of operations accounts and net realized gain (loss) on investments are
translated at the rates prevailing at the dates of transactions.
 
  Reported net realized gains and losses on foreign currency transactions
represent net gains and losses from sales and maturities of forward foreign
currency contracts, disposition of foreign currencies, currency gains and
losses realized between trade and settlement dates of security transactions,
and the difference between the amounts of net investment income accrued and
the U.S. dollar amount actually received.
 
  Dividends: A dividend of its net investment income will be declared and
distributed daily by the Money Market Portfolio. Dividends of net investment
income will be declared and distributed monthly by other Portfolios. Each
Portfolio will distribute all of its net realized capital gains annually, at
the end of its fiscal year.
