DEAR FELLOW SHAREHOLDERS:

The Year 2000 is fast approaching and people around the world are getting ready
to celebrate this historic transition to a new millennium. At John Hancock
Funds, we share the excitement, but we aren't popping the champagne corks just
yet. Rather, we are staying on the course that we set more than two years ago to
ensure that the transition to a new millennium is a smooth one for our
shareholders.

As many already know, the Year 2000 has created more than the prospect of New
Year's festivities of epic proportions. It has also presented the world with a
challenge: making sure that older computers, and any equipment powered by
computer chips, can properly read and process the date "00" as 2000, not 1900.
Much has been written about how the world will weather the change. Some view it
as a non-event, while others see the potential for disruptions. How much
disruption, and for how long, depends on whom you talk to.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Edward J. Boudreau, Jr., Chairman and Chief Executive
Officer, flush right next to second paragraph.]
- --------------------------------------------------------------------------------

As a company, we recognize that the Year 2000 ("Y2K") phenomenon is an important
issue to be dealt with and we have made it a top priority. Two years ago, John
Hancock Funds put a full-time team of experts on the case and established a
company-wide program to evaluate all computer applications and to modify or
replace those that needed changing.

These modifications and replacements are nearly done, and the tests of all our
systems are on schedule for completion by the end of July. The rest of 1999 will
be spent testing with our business partners and continuing to participate in
industry testing. We have also established additional contingency plans beyond
our regular ones to prepare for any challenges that the Year 2000 might present.
In the end, John Hancock will spend approximately $90-$95 million to ensure we
make a successful transition to the Year 2000.

Throughout 1999, each of our quarterly "Fundamentals" newsletters is featuring
articles with more detailed information on Y2K matters of importance to our
shareholders. I encourage you to read them, or contact one of our Customer
Service Representatives at 1-800-225-5291 for another copy. For your own peace
of mind, we also recommend that you save your 1999 statements, especially those
you receive between October and December, so that you are able to check them
against the first one you receive in 2000. It's a measure of prudence, not
panic. Good record keeping is part of good planning.

No one knows how the dawning of the new millennium will unfold. Although we
cannot make any ironclad assurances, we are confident that the steps we have
taken will provide shareholders with as smooth a transition as possible. Once
that occurs, we will happily raise our glasses to toast the New Year, future
prosperity and our hopes to serve you well into the 2000's.

Sincerely,

/s/Edward J. Boudreau, Jr.

                        environment for small-cap stocks
                        --------------------------------

Effective June 1, 1999, John Hancock Emerging Growth Fund's name was changed to
John Hancock Small Cap Growth Fund to better describe how the Fund invests.

John Hancock Small Cap Growth Fund posted very strong returns over the last six
months during an up-and-down period for small-company stocks. After lagging
their larger-company counterparts throughout most of 1998, small-cap stocks
caught fire just weeks before the period began, thanks largely to interest-rate
cuts by the Federal Reserve Board. Because they tend to fund their growth by
borrowing money, small-cap companies benefit more than larger companies from
lower rates. The Fed's actions also helped restore investor confidence and
pumped liquidity into the global financial system. A third rate cut in November
helped extend the small-cap rally through the remainder of 1998 by attracting
investors looking for inexpensive alternatives to high-flying large-cap names.
The small-cap market's advance was limited almost exclusively to growth stocks -
those that exhibit fast rates of earnings and other growth, leaving behind
small-cap value stocks - those that seem bargain-priced based on price/earnings
ratios and other measures.

         By early 1999, however, sentiment turned against small-cap stocks of
both the growth and value variety. Inflationary fears re-emerged on news that
the economy had expanded at a much

quicker-than-expected pace in the final three months of 1998 and put pressure on
small-company stock prices. Practically the only exceptions to this rule were
red-hot technology stocks - particularly those related to the Internet.
Investors seemingly couldn't get enough of these stocks, many of which posted
triple-digit gains in the first four months of this year.

         Given the gyrating environment for small-company growth stocks, we're
gratified that the Fund handily outpaced its benchmark and its peers. For the
six-month period ended April 30, 1999, John Hancock Small Cap Growth Fund's
Class A, Class B and Class C shares posted total returns of 33.54%, 33.16% and
33.03%, respectively, at net asset value. By contrast, the average small-cap
fund returned 14.68%, according to Lipper, Inc.1, and the Russell 2000 Growth
Index returned 25.74%. Keep in mind that your net asset value return will be
different from the Fund's performance if you were not invested in the Fund for
the entire period and did

Internet  hot...

By far the strongest sector in both the market and the Fund during this period
was technology. A number of strategic moves that we made among various
technology sub-sectors going into the period held the keys to our recent
outperformance. Last November, we were focused on semiconductor manufacturers
and semiconductor capital equipment makers such as Novellus Systems, PMC-Sierra,
Semtech and Level One Communications. We had purchased these stocks last summer
after they experienced a rather severe correction when investors feared that
protracted problems in the Far East would translate into a slowdown in
semiconductor chip and equipment orders. At the time, we believed the market
overreacted and that the group was therefore attractively priced. As we
expected, orders from Asia firmed up and boosted our holdings. More recently,
we've tilted our semiconductor holdings more toward companies that make chips or
equipment for the fast-growing telecommunications industry, such as RF Micro
Devices.

         Perhaps our strongest performers during the period were our Internet
holdings, especially given investors' near-mania for the group in 1999. We had
also added to our Internet stocks last summer, after they, too, fell victim to
negative investor sentiment. That strategy proved beneficial when companies like
RealNetworks, which provides audio and video technology for the Internet, and
networking company AboveNet Communications posted double-digit gains by the end
of the period.

Another strong performer was Multex.com, which transmits brokerage research via

 ...software, health services not

By contrast, our technology holdings in the software and service sectors
performed poorly and detracted from performance. Investors became increasingly
fearful that the approach of the Year 2000 would stymie demand for software and
services, since few companies would want to implement new software while Y2K
issues remained. Even companies that continued to post good earnings and meet
expectations suffered from the negative sentiment, such as Whittman-Hart, which
provides technology services such as web design and software installation for
medium-sized businesses.

         Health-care service companies also performed poorly during the period.
Changes in Medicare reimbursement levels continued to weigh heavily on this
group of nursing homes and assisted-living centers, many of which we sold before
the period ended.

New additions

Our search for companies with strong and sustainable revenue and earnings
growth, dominant market share and proven and effective management led us to a
number of new ideas, including retailers who serve the teenage market such as
bebe stores, Pacific Sunwear of California and Wet Seal. The U.S. teen
population is growing twice as fast as almost any other American age group.
What's more, they have money and they spend it.

         We also added to the Fund's stake in so-called "clecs," which are
telephone companies that serve small and mid-sized business. Many of these
companies, such as NEXTLINK Communications, have enjoyed consistent and strong
earnings growth as they grab market share away from more traditional telephone
companies.

Outlook

Our outlook for stocks in general is upbeat. Continued healthy economic growth
coupled with low inflation, low interest rates and low unemployment should
continue to favor stocks. Based on that view, we believe that the outlook for
earnings is quite good. As for small-company stocks, even with their recent
uptick, their valuations remain compelling and their earnings growth rates
attractive, meaning small caps remain overdue for a more sustained rally. The
Fund's diversified approach has helped sustain it during ups and downs of the
small-cap market over the last few years, and should continue to serve the Fund
well.

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Small Cap Growth Fund. Total return measures
the change in value of an investment from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 5%. (Prior to May 15, 1995, the maximum applicable sales charge for
Class A shares was 5.75%.) Class B performance reflects a maximum contingent
deferred sales charge (maximum 5% and declining to 0% over six years). Class C
performance includes a contingent deferred sales charge (1% declining to 0%
after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus before you invest or send money.

                    WHAT HAPPENED TO A $10,000 INVESTMENT...

The charts on the right show how much a $10,000 investment in the John Hancock
Small Cap Growth Fund would be worth, assuming all distributions were reinvested
for the period indicated. For comparison, we've shown the same $10,000
investment in both the Russell 2000 Index and the Russell 2000 Growth Index. The
Russell 2000 Index is an unmanaged, small-cap index that is comprised of 2,000
stocks of U.S.- domiciled companies whose common stocks trade in the United
States on the New York Stock Exchange, American Stock Exchange and NASDAQ. The
Russell 2000 Growth Index is an unmanaged index that contains those securities
from the Russell 2000 Index with a greater-than-average growth orientation. Past
performance is not indicative of future results.

                   John Hancock Funds - Small Cap Growth Fund


(UNAUDITED)
NOTE A -
ACCOUNTING POLICIES

John Hancock Series Trust (the "Trust") is a diversified open-end management
investment company registered under the Investment Company Act of 1940. The
Trust consists of two series portfolios: John Hancock Small Cap Growth Fund (the
"Fund") and John Hancock Global Technology Fund. Prior to June 1, 1999, the Fund
was known as John Hancock Emerging Growth Fund. The other series of the Trust is
reported in separate financial statements. The investment objective of the Fund
is to seek long-term growth of capital through investing in emerging companies
(market capitalization of less than $1 billion).

The Trustees have authorized the issuance of multiple classes of shares of the
Fund, designated as Class A, Class B and Class C shares. The shares of each
class represent an interest in the same portfolio of investments of the Fund and
have equal rights to voting, redemptions, dividends and liquidation, except that
certain expenses, subject to the approval of the Trustees, may be applied
differently to each class of shares in accordance with current regulations of
the Securities and Exchange Commission and the Internal Revenue Service.
Shareholders of a class which bears distribution and service expenses under
terms of a distribution plan have exclusive voting rights to that distribution
plan.

         Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value. All portfolio
transactions initially expressed in terms of foreign currencies have been
translated into U.S. dollars as described in "Foreign Currency Translation"
below.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
Inc., may participate in a joint repurchase agreement. 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 Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Dividend income on investment securities
is recorded on the ex-dividend date or, in the case of some foreign securities,
on the date thereafter when the Fund is made aware of the dividend. Interest
income on investment securities is recorded on the accrual basis. Foreign income
may be subject to foreign withholding taxes, which are accrued as applicable.

         The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund with
respect to each class of shares will be calculated in the same manner, at the
same time and will be in the same amount, except for the effect of expenses that
may be applied differently to each class.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are calculated at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class and the specific expense
rate(s) applicable to each class.


EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not readily

                                       17
<PAGE>

============================NOTES TO FINANCIAL STATEMENTS=======================

                   John Hancock Funds - Small Cap Growth Fund


identifiable to a specific fund are allocated in such a manner as deemed
equitable, taking into consideration, among other things, the nature and type of
expense and the relative sizes of the funds.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. Effective March 12, 1999,
the Fund entered into a syndicated line of credit agreement with various banks,
and the agreements previously in effect were terminated. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund, based on its borrowings. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The
maximum loan balance during the period amounted to $11,740,817. The annualized
interest rate charged during the period ranged from 5.2500% thru 5.8125%. At
April 30, 1999, there were no outstanding borrowings.

FOREIGN CURRENCY TRANSLATION All assets and 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. Transactions affecting
statement of operations accounts and net realized gain/(loss) on investments are
translated at the rates prevailing at the dates of the transactions.

         The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held. Such
fluctuations are included with the net realized and unrealized gain or loss from
investments.

         Reported net realized foreign exchange gains or losses arise from sales
of foreign currency, currency gains or losses realized between the trade and
settlement dates on securities transactions and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains or losses arise from changes in the
value of assets and liabilities other than investments in securities at fiscal
year end, resulting from changes in the exchange rate.


NOTE B -
MANAGEMENT FEE AND TRANSACTIONS
WITH AFFILIATES AND OTHERS

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of 0.75% of Fund's average daily net asset value.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the period ended
April 30, 1999, net sales charges received with regard to sales of Class A
shares amounted to $232,063. Out of this amount, $32,359 was retained and used
for printing prospectuses, advertising, sales literature and other purposes,
$165,016 was paid as sales commissions to unrelated broker-dealers and $34,688
was paid as sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer, formerly known as John Hancock
Distributors, Inc. The Adviser's indirect parent, John Hancock Mutual Life
Insurance Company ("JHMLICo"), is the indirect sole shareholder of Signator
Investors.

         Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses related to providing distribution related services to the Fund in
connection with the sale of

Class B shares. For the period ended April 30, 1999, contingent deferred sales
charges paid to JH Funds amounted to $521,472.

         Class C shares which are redeemed within one year of purchase will be
subject to a contingent deferred sales charge ("CDSC") at a rate of 1.0% of the
lesser of the current market value at the time of redemption or the original
purchase cost of the shares being redeemed. Proceeds from the CDSC are paid to
JH Funds and are used in whole or in part to defray its expenses related to
providing distribution related services to the Fund in connection with the sale
of Class C shares. For the period ended April 30, 1999, contingent deferred
sales charges paid to JH Funds amounted to $225.

         In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.25% of Class A average daily net assets and 1.00% of Class B and Class C
average daily net assets, to reimburse JH Funds for its distribution and service
costs. Up to a maximum of 0.25% of such payments may be service fees as defined
by the amended Rules of Fair Practice of the National Association of Securities
Dealers. Under the amended Rules of Fair Practice, curtailment of a portion of
the Fund's 12b-1 payments could occur under certain circumstances.

         The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

         The Fund has an agreement with the Adviser to perform necessary tax and
financial management services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

         Mr. Edward J. Boudreau, Jr., Mr. Stephen L. Brown, Ms. Anne C. Hodsdon
and Mr. Richard S. Scipione are trustees and/or officers of the Adviser and/or
its affiliates, as well as Trustees of the Fund. The compensation of
unaffiliated Trustees is borne by the Fund. The unaffiliated Trustees may elect
to defer for tax purposes their receipt of this compensation under the John
Hancock Group of Funds Deferred Compensation Plan. The Fund makes investments
into other John Hancock funds, as applicable, to cover its liability for the
deferred compensation. Investments to cover the Fund's deferred compensation
liability are recorded on the Fund's books as an other asset. The deferred
compensation liability and the related other asset are always equal and are
marked to market on a periodic basis to reflect any income earned by the
investment as well as any unrealized gains or losses. At April 30, 1999, the
Fund's investment to cover the deferred compensation liability had unrealized
appreciation of $4,976.

================================================================================

DEAR FELLOW SHAREHOLDERS:

The Year 2000 is fast approaching and people around the world are getting ready
to celebrate this historic transition to a new millennium. At John Hancock
Funds, we share the excitement, but we aren't popping the champagne corks just
yet. Rather, we are staying on the course that we set more than two years ago to
ensure that the transition to a new millennium is a smooth one for our
shareholders.

As many already know, the Year 2000 has created more than the prospect of New
Year's festivities of epic proportions. It has also presented the world with a
challenge: making sure that older computers, and any equipment powered by
computer chips, can properly read and process the date "00" as 2000, not 1900.
Much has been written about how the world will weather the change. Some view it
as a non-event, while others see the potential for disruptions. How much
disruption, and for how long, depends on whom you talk to.

- --------------------------------------------------------------------------------
[A 1" x 1" photo of Edward J. Boudreau, Jr., Chairman and Chief Executive
Officer, flush right next to second paragraph.]
- --------------------------------------------------------------------------------

As a company, we recognize that the Year 2000 ("Y2K") phenomenon is an important
issue to be dealt with and we have made it a top priority. Two years ago, John
Hancock Funds put a full-time team of experts on the case and established a
company-wide program to evaluate all computer applications and to modify or
replace those that needed changing. These modifications and replacements are
nearly done, and the tests of all our systems are on schedule for completion by
the end of July. The rest of 1999 will be spent testing with our business
partners and continuing to participate in industry testing. We have also
established additional contingency plans beyond our regular ones to prepare for
any challenges that the Year 2000 might present. In the end, John Hancock will
spend approximately $90-$95 million to ensure we make a successful transition to
the Year 2000.

Throughout 1999, each of our quarterly "Fundamentals" newsletters is featuring
articles with more detailed information on Y2K matters of importance to our
shareholders. I encourage you to read them, or contact one of our Customer
Service Representatives at 1-800-225-5291 for another copy. For your own peace
of mind, we also recommend that you save your 1999 statements, especially those
you receive between October and December, so that you are able to check them
against the first one you receive in 2000. It's a measure of prudence, not
panic. Good record keeping is part of good planning.

No one knows how the dawning of the new millennium will unfold. Although we
cannot make any ironclad assurances, we are confident that the steps we have
taken will provide shareholders with as smooth a transition as possible. Once
that occurs, we will happily raise our glasses to toast the New Year, future
prosperity and our hopes to serve you well into the 2000's.

Sincerely,

/s/Edward J. Boudreau, Jr.

           Technology stocks lead market's advance in last six months
           ----------------------------------------------------------


After two months of severely underperforming the stock market as a whole,
technology stocks came roaring back to life in the past six months. A large part
of their success stemmed from their cheap valuations compared to other industry
sectors. Investors had severely punished technology stocks in the summer of 1998
when it appeared that the world was on the brink of an economic crisis. By
January 1999, however, the U.S. economy continued to grow at a healthy, yet
non-inflationary pace, and the global economy was perceived to be on the mend.

         Another powerful source behind the surge in tech stocks was the
continuing Internet explosion. Selling goods to the public over the Internet is
already an $8 billion business. Given the enormous growth potential of this
industry, investors seemingly couldn't get enough of Internet and related
companies, sending their share prices skyrocketing.

Internet connects

For the six months ended April 30, 1999, John Hancock Global Technology Fund's
Class A and Class B shares posted total returns of 70.05% and 69.53%,
respectively, at net asset value. Those returns were well ahead of the average
science and technology fund's 60.35% return, according to Lipper, Inc.1 The
Fund's Class C shares, which were launched on March 1, 1999, returned 19.02% for
the first two months of operations. Keep in mind that your net asset value
return will be different from the Fund's performance if you were not invested in
the Fund for the entire period and did not reinvest all distributions. Please
see pages six and seven for longer-term performance information.

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

         Not surprisingly, our Internet-related holdings were among our best
performers during the period. America Online (AOL), which was also our largest
position throughout the period, continued to prosper. As the country's largest
Internet service provider, AOL dominated its competitors by signing up millions
of new customers and making deals with many advertisers and users. As AOL's
share price doubled, and then tripled, we pared back our holdings. Even though
we believe it has a great franchise and will continue to enjoy tremendous
growth, we don't want the portfolio's performance to be overly reliant on the
performance of any one or even a handful of stocks. Our holding in networking
company Cisco Systems was also quite rewarding. Its stock nearly doubled during
the period, a reflection of the tremendous benefits bestowed on companies that
provide goods and services needed to accommodate the rise of the Internet. Other
strong performers were Metromedia Fiber Network and Global Crossing,

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

both of which more than tripled in price during the past six months. These
companies offer bandwidth, which refers to the data transmission capacity of a
network. Finally, we saw gains in excess of 200% each from RealNetworks, which
provides software and services enabling PC users to send and receive "real-time"
media; DoubleClick, which provides services for Internet advertisers and
Inktomi, developer and marketer of Internet software.

         Beyond Internet-related companies, there were significant gains from
other segments of the technology group as well. Software giant Microsoft enjoyed
solid returns as it dominated the world's software market. Adjusting for a
two-for-one stock split, Microsoft shares gained more than 70%. Our holdings in
information storage companies EMC Corp. and Network Appliance also did quite
well, in part because of the realization that there is a rapidly growing need
for storage, in part due to the Internet.

         The rising technology tide didn't lift all boats, however. Our holdings
in software security company Network Associates proved to be very disappointing.
Its shares plummeted when it came under scrutiny for accounting policies,
followed by news that its first quarter 1999 earnings were much lower than
expected. Enterprise software companies were particularly poor performers during
this time frame, due to fears that Y2K would dampen software spending for the
balance of 1999. Because we believe those fears were overblown and that
enterprise stocks were oversold for the most part, we added to our holdings in
BMC Software and Compuware at what we viewed as very attractive prices. That
said, we reduced our holdings in Computer Associates International because of
company-specific problems.

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

Broadening out

We've recently added to our stake in small and mid-sized technology companies.
That's where we found some of the better bargains, with many small and
medium-sized stocks offering significantly more attractive valuations than their
larger-company counterparts. In addition, we think that the good performance
enjoyed by larger tech companies will spill over to the small and mid-sized
companies in the not-so-distant future. During the past six months we added
several small semiconductor equipment companies, including Applied Science &
Technology, ASM Lithography Holding and Veeco Instruments, to the portfolio. In
the computer services area we added to positions in Mercury Interactive and
Fundtech.

Outlook

The faster and the higher it climbed, the more volatile the technology sector
became during the past six months. We wouldn't be surprised if that trend
continued for a while, punctuated by periods when technology stocks fall back
for short periods of time. However, we believe that technology stocks will
continue to outperform the overall stock market during the next six to 12
months. That said, we think the magnitude of that outperformance will be much
more moderate than we've witnessed over the past six months. Much of the
valuation discrepancy that existed prior to the beginning of the period has been
erased by the huge gains technology stocks recently have enjoyed. Looking ahead,
technology stocks will need to post continued earnings and profit growth in
order to stay ahead of the overall market. And on those counts, we remain quite
optimistic. First-quarter earnings for the technology group were significantly
stronger than earnings posted by other sectors. With no signs that the demand
for technology will diminish, we think earnings growth will remain strong.

International investing involves special risks such as political, economic and
currency risks and differences in accounting standards and financial reporting.
Sector investing is subject to greater risks than the market as a whole.

                             A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Global Technology Fund. Total return measures
the change in value of an investment from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 5%. Different sales charge schedules for Class A shares were in effect
prior to March 1987 and are not reflected in the performance information. Class
B performance reflects a maximum contingent deferred sales charge (maximum 5%
and declining to 0% over six years). Class C performance includes a contingent
deferred sales charge (1% declining to 0% after one year).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus for a discussion of the risks associated with international
investing, including currency and political risks and differences in accounting
standards and financial reporting, before you invest or send money.

                  John Hancock Funds - Global Technology Fund


(UNAUDITED)
NOTE A -
ACCOUNTING POLICIES

John Hancock Series Trust (the "Trust") is a diversified open-end management
investment company, registered under the Investment Company Act of 1940. The
Trust consists of two series: John Hancock Global Technology Fund (the "Fund")
and John Hancock Small Cap Growth Fund. Prior to June 1, 1999, John Hancock
Small Cap Growth Fund was known as John Hancock Emerging Growth Fund. The other
series of the Trust is reported in separate financial statements. The investment
objective of the Fund is to achieve long-term capital growth by investing
principally in equity securities of companies that rely extensively on
technology in their product development or operations. Income is a secondary
objective.

         The Trustees have authorized the issuance of multiple classes of shares
of the Fund, designated as Class A, Class B and Class C shares. The Trustees
authorized the issuance of Class C shares effective March 1, 1999. The shares of
each class represent an interest in the same portfolio of investments of the
Fund and have equal rights to voting, redemptions, dividends and liquidation,
except that certain expenses, subject to the approval of the Trustees, may be
applied differently to each class of shares in accordance with current
regulations of the Securities and Exchange Commission and the Internal Revenue
Service. Shareholders of a class which bears distribution and service expenses
under terms of a distribution plan have exclusive voting rights to that
distribution plan.

         Significant accounting policies of the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost, which approximates market value. All portfolio
transactions initially expressed in terms of foreign currencies have been
translated into U.S. dollars as described in "Foreign Currency Translation."

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc. (the "Adviser"), a wholly owned subsidiary of The Berkeley Financial Group,
may participate in a joint repurchase agreement. 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 Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis. Capital gains realized
on some foreign securities are subject to foreign taxes and are accrued, as
applicable.

FEDERAL INCOME TAXES The Fund qualifies as a "regulated investment company" by
complying with the applicable provisions of the Internal Revenue Code and will
not be subject to federal income tax on taxable income which is distributed to
shareholders. Therefore, no federal income tax provision is required.

DIVIDENDS, INTEREST AND DISTRIBUTIONS Dividend income on investment securities
is recorded on the ex-dividend date. Interest income on investment securities is
recorded on the accrual basis.

         The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund with
respect to each class of shares will be calculated in the same manner, at the
same time and will be in the same amount, except for the effect of expenses that
may be applied differently to each class.

DISCOUNT ON SECURITIES The Fund accretes discount from par value on securities
purchased from either the date of issue or the date of purchase over the life of
the security, as required by the Internal Revenue Code.

=========================NOTES TO FINANCIAL STATEMENTS==========================

                  John Hancock Funds - Global Technology Fund


CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are calculated at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution and service fees, if any, are calculated daily at the class level
based on the appropriate net assets of each class and the specific expense
rate(s) applicable to each class.

EXPENSES The majority of the expenses of the Trust are directly identifiable to
an individual fund. Expenses which are not identifiable to a specific fund are
allocated in such a manner as deemed equitable, taking into consideration, among
other things, the nature and type of expense and the relative size of the funds.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates estimates made by
management in determining the reported amounts of assets, liabilities, revenues
and expenses of the Fund. Actual results could differ from these estimates.

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. Effective March 12, 1999,
the Fund entered into a syndicated line of credit agreement with various banks
and the agreements previously in effect were terminated. This agreement enables
the Fund to participate with other funds managed by the Adviser in an unsecured
line of credit with banks which permit borrowings up to $500 million,
collectively. Interest is charged to each fund, based on its borrowings. In
addition, a commitment fee is charged based on the average daily unused portion
of the line of credit and is allocated among the participating funds. The Fund
had no borrowing activity for the period ended April 30, 1999.

FOREIGN CURRENCY TRANSLATION 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. Transactions affecting
statement of operations accounts and net realized gain/(loss) on investments are
translated at the rates prevailing at the dates of the transactions.

         The Fund does not isolate that portion of the results of operations
resulting from changes in foreign exchange rates on investments from the
fluctuations arising from changes in market prices of securities held. Such
fluctuations are included with the net realized and unrealized gain or loss from
investments.

         Reported net realized foreign exchange gains or losses arise from sales
of foreign currency, currency gains or losses realized between the trade and
settlement dates on securities transactions and the difference between the
amounts of dividends, interest and foreign withholding taxes recorded on the
Fund's books and the U.S. dollar equivalent of the amounts actually received or
paid. Net unrealized foreign exchange gains and losses arise from changes in the
value of assets and liabilities, other than investments in securities at fiscal
year end, resulting from changes in the exchange rate.

OPTIONS Listed options will be valued at the last quoted sales price on the
exchange on which they are primarily traded. Over-the-counter options are valued
at the mean between the last bid and asked prices. Upon the writing of a call or
put option, an amount equal to the premium received by the Fund will be included
in the Statement of Assets and Liabilities as an asset and corresponding
liability. The amount of the liability will be subsequently marked to market to
reflect the current market value of the written option.

         The Fund may use option contracts to manage its exposure to the stock
market. Writing puts and buying calls will tend to increase the Fund's exposure
to the underlying instrument and buying puts and writing calls will tend to
decrease the Fund's exposure to the underlying instrument, or hedge other Fund
investments.

         The maximum exposure to loss for any purchased options will be limited
to the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

         Risks may also arise if counterparties do not perform under the
contract's terms ("credit risk"), or if the Fund is unable to offset a contract
with a counterparty on a timely basis ("liquidity risk"). Exchange-

traded options have minimal credit risk as the exchanges act as counterparties
to each transaction, and only present liquidity risk in highly unusual market
conditions. To minimize credit and liquidity risks in over-the-counter option
contracts, the Fund will continuously monitor the creditworthiness of all its
counterparties.

         At any particular time, except for purchased options, market or credit
risk may involve amounts in excess of those reflected in the Fund's Statement of
Assets and Liabilities.

NOTE B -
MANAGEMENT FEE AND TRANSACTIONS
WITH AFFILIATES AND OTHERS

The Adviser is responsible for managing the Fund's investment business affairs
and overseeing the investment activities of the sub-adviser. The Adviser has a
sub-investment management contract with American Fund Advisors, Inc. (the
"Sub-Adviser"), under which the Sub-Adviser, subject to the review of the
Trustees and the overall supervision of the Adviser, provides the Fund with
investment services and advice with respect to investment transactions. Under
the present investment management contract, the Fund pays a monthly management
fee to the Adviser, equivalent, on an annual basis, to the sum of (a) 0.85% of
the first $100,000,000 of the Fund's average daily net asset value and (b) 0.75%
of the Fund's average daily net asset value in excess of $100,000,000. The
Adviser pays the Sub-Adviser a monthly management fee, equivalent, on an annual
basis, to the sum of (a) 0.35% of the first $100,000,000 of the Fund's average
daily net asset value and (b) 40% of the investment advisory fee received by the
Adviser on amounts over $100,000,000. The Fund pays a monthly administrative fee
at the rate of $100,000 per annum to the Adviser for performance of
administrative services to the Fund.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the period ended
April 30, 1999, net sales charges received with regard to sales of Class A
shares amounted to $596,691. Out of this amount, $91,713 was retained and used
for printing prospectuses, advertising, sales literature and other purposes,
$405,359 was paid as sales commissions to unrelated broker-dealers and $99,619
was paid as sales commissions to sales personnel of Signator Investors, Inc.
("Signator Investors"), a related broker-dealer, formerly known as John Hancock
Distributors, Inc. The Adviser's indirect parent, John Hancock Mutual Life
Insurance Company ("JHMLICo"), is the indirect sole shareholder of Signator
Investors.

         Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the


                                       18

time of redemption or the original purchase cost of the shares being redeemed.
Proceeds from the CDSC are paid to JH Funds and are used in whole or in part to
defray its expenses related to providing distribution related services to the
Fund in connection with the sale of Class B shares. For the period ended April
30, 1999, contingent deferred sales charges paid to JH Funds amounted to
$216,418.

         Class C shares which are redeemed within one year of purchase will be
subject to a contingent deferred sales charge ("CDSC") at a rate of 1.00% of the
lesser of the current market value at the time of redemption or the original
purchase cost of the shares being redeemed. Proceeds from the CDSC are paid to
JH Funds and are used in whole or in part to defray its expenses related to
providing distribution related services to the Fund in connection with the sale
of Class C shares. For the period ended April 30, 1999, contingent deferred
sales charges paid to JH Funds amounted to $5.

         In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted a Distribution Plan with
respect to Class A, Class B and Class C pursuant to Rule 12b-1 under the
Investment Company Act of 1940. Accordingly, the Fund will make payments to JH
Funds for distribution and service expenses, at an annual rate not to exceed
0.30% of Class A average daily net assets and 1.00% of Class B and Class C
average daily net assets, to reimburse JH Funds for its distribution and service
costs. Up to a maximum of 0.25% of such payments may be service fees as defined
by the amended Rules of Fair Practice of the National Association of Securities
Dealers. Under the amended Rules of Fair Practice, curtailment of a portion of
the Fund's 12b-1 payments could occur under certain circumstances.

         The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of JHMLICo. The
Fund pays the transfer agent fee based on the number of shareholder accounts and
certain out-of-pocket expenses.

         Mr. Edward J. Boudreau, Jr., Mr. Stephen L. Brown, Ms. Anne C. Hodsdon
and Mr. Richard S. Scipione are Trustees and/or officers of the Adviser and/or
its affiliates, as well as Trustees of the Fund and Mr. Barry J. Gordon is a
director and officer of the Sub-Adviser. The compensation of unaffiliated
Trustees is borne by the Fund. The unaffiliated Trustees may elect to defer, for
tax purposes, their receipt of this compensation under the John Hancock Group of
Funds Deferred Compensation Plan. The Fund makes investments into other John
Hancock funds, as applicable, to cover its liability for the deferred
compensation. Investments to cover the Fund's deferred compensation liability
are recorded on the Fund's books as an other asset. The deferred compensation
liability and the related other asset are always equal and are marked to market
on a periodic basis to reflect any income earned by the investment as well as
any unrealized gains or losses. At April 30, 1999, the Fund's investments to
cover the deferred compensation liability had unrealized appreciation of $1,687.
