                               CHAIRMAN'S MESSAGE

DEAR FELLOW SHAREHOLDERS:

[A 1 1/4" x 1" photo of Edward J. Boudreau Jr., Chairman and Chief Executive
Officer, flush right, next to second paragraph.]

Educating shareholders has always been one of the most important
responsibilities of a mutual fund company. But that challenge has taken on new
significance in the past several years. Looking at the most recent statistics,
you can see why. According to the Investment Company Institute, the mutual fund
industry now manages more than $2.3 trillion for investors. More than half of
that money has come into mutual funds in just the last four years. Today, there
are more than 95 million mutual fund shareholder accounts. That's up from 12
million in 1980. These are people, like you, who are investing in mutual funds
to save for a home, to send their children to college or to build a nest egg for
a comfortable retirement. This explosive growth, coupled with the growing
complexity of the financial landscape, has made all of us in the mutual fund
industry work harder to inform our shareholders.

   At John Hancock Funds, we strive to educate you about all aspects of your
fund: the performance, the strategies and the holdings. We want you to fully
understand what you own. We want you to have realistic expectations of the
potential rewards as well as the potential risks of your investment. These
shareholder reports -- which we send you twice a year -- are the best way to
give you the most in-depth and up-to-date information.

   In the message that follows, the portfolio manager gives a candid commentary
on the market environment; the factors that affected performance; the Fund's
current investment strategies; and the outlook for the months ahead.

   The ensuing financial statements provide a comprehensive look at the fund's
statistics and holdings.

   We hope you find these shareholder reports a useful tool in evaluating your
investments. Of course, if you have any questions or need more information, feel
free to call one of our customer service representatives on our toll-free line
at 1-800-225-5291, from 8:00 a.m. to 8:00 p.m. eastern time, Monday through
Friday.


Sincerely,


/s/ Edward J. Boudreau, Jr.

             MUNICIPAL BOND MARKET BUOYED BY FALLING INTEREST RATES,
           STRONGER DEMAND; DIMINISHED SUPPLY COULD HELP EXTEND RALLY

In May 1995, Thomas C. Goggins became portfolio manager of John Hancock
Tax-Exempt Income Fund. Mr. Goggins is senior vice president at John Hancock
Funds and heads up the company's team of municipal bond portfolio managers and
analysts. He is also a member of the portfolio management team of John Hancock
Tax-Free Bond Fund.

After being battered by higher interest rates and weak demand during most of
1994, municipal bonds reversed course during the first half of 1995 and enjoyed
one of their strongest periods of the decade. Beginning in January, the economy
appeared to be slowing and inflation was low. As a result, investors became less
worried that the Federal Reserve Board would continue its 1994 policy of raising
short-term interest rates. An added positive was that demand for municipal bonds
started to strengthen, bucking up against limited supply. All in all, municipals
were the top performing fixed-income category during the first quarter of this
year.

   In the second quarter, however, municipals hit a few bumps. One was talk of a
flat tax in April, which if enacted, would eliminate the tax-free advantage
municipals now enjoy. In our view, however, it's unlikely that a flat tax will
ever be enacted, and the market appears to have overreacted. Later in the
quarter, voters in Orange County, California failed to pass a tax

bill intended to pay for the county's 1994 investment losses. These events
cast a slight pall over the municipal market, but not enough to eliminate its
earlier gains.

A LOOK AT PERFORMANCE

For the six months ended June 30, 1995, John Hancock Tax-Exempt Income Fund's
Class A and Class B shares posted returns of 8.29% and 7.76%, respectively, at
net asset value. That was a shade below the average general municipal bond
fund's return of 9.01% for the same period, according to Lipper Analytical
Services.(1)

   The primary factor in the Fund's performance was its duration. Duration
measures a fund's price volatility for a given change in interest rates. The
longer a fund's duration, the more sensitive its share price is to interest rate
changes. For most of the period, the Fund's duration was largely similar to that
of many other funds of its type.

   Toward the end of the period, there wasn't much difference in yield between
short- and long-term bonds. In other words, the yield curve was relatively flat.
So there was little incentive for investors to take on the added interest-rate
risk of longer-term bonds. For this reason we sold some longer-term bonds and
replaced them with shorter-term bonds. The net effect was a shorter duration for
the Fund. Going forward, we will actively manage duration, shortening and
lengthening as market conditions warrant.

FOCUS ON SECTORS

During the period, we built up our weighting in health-care bonds to nearly 13%.
While the health-care industry has recently been faced with a number of
competitive and cost pressures, we continue to like health-care bonds because of
their attractive yields. Using careful analysis and research, we look for
hospitals with strong participation from health-maintenance organizations and
low cost structures. We think that these are the key to finding the hospitals
which will be the winners in this more competitive environment.

   More recently, we've found opportunities in electric utility bonds, which
make up the Fund's largest sector concentration at about 19% of assets. Many
investors shunned these bonds last year due to worries about increased
competition in the utility industry. After they had fallen to quite attractive
levels, we stepped in and start buying these bonds. In our view, true
competition is a lot farther off than the municipal market has taken into
account. North Carolina Eastern Municipal Power Agency was one addition to this
sector.

OUTLOOK

Continued debate about various tax reform proposals could add volatility to the
municipal market in the months to come. But as we mentioned earlier, we don't
believe that the flat tax proposal -- the one which would most negatively impact
municipal bonds -- is likely to be enacted.

   Looking foward, we remain optimistic about the municipal bond market. One
reason is the long-term trend toward diminished supply of municipal bonds.
That's because municipalities aren't planning as many capital projects as voters
become more reluctant to pay for them with higher taxes. What's more, many of
the municipalities that could refinance their borrowings of the high-flying
'80's at lower rates have already done so. Let's take a look at the numbers. In
1993, municipal bond supply stood at $292 billion. By 1994, supply had fallen
off by about half the previous year's level and it's expected to be about $120
billion by the end of 1995. Decreasing supply and constant demand should be a
positive for the municipal bond market. In addition, municipal bonds continue to
offer a relatively attractive after-tax yield, which may attract new investors.

   In our view, the economy is growing slowly but steadily. It's not in any real
danger of overheating or dipping into a recession. Therefore, we believe that
inflation will stay low and interest rates will stabilize. As a result, the bulk
of the municipal bond market's performance will come from income, rather than
big price gains. So we'll continue to look for opportunities to improve and
enhance the Fund's yield.

                             A LOOK AT PERFORMANCE

The tables on the right show the cumulative total returns and the average annual
total returns for John Hancock Tax-Exempt Income Fund. Total return is a
performance measure that equals the sum of all income and capital gains
dividends, assuming reinvestment of these distributions, and the change in the
price of the fund's shares, expressed as a percentage of the fund's share.
Performance figures include the maximum applicable sales charge of 4.5% for
Class A shares. The effect of the maximum contingent deferred sales charge for
Class B shares (maximum 5% and declining to 0% over six years) is included in
Class B performance. Remember that all figures represent past performance and
are no guarantee of how the Fund will perform in the future. Also, 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.

Note: Participant-directed defined-contribution plans with at least 100 eligible
employees at inception of the Fund account may purchase Class A shares without
an initial sales charge as of March 15, 1995. If those shares are redeemed,
however, during the year following the calendar year end during which they were
purchased, a contingent deferred sales charge will be assessed.

The charts on the right show how much a $10,000 investment in the John Hancock
Tax-Exempt Income Fund would be worth on June 30, 1995, assuming you have been
invested for the past ten years or since the day each class of shares started
and have reinvested all distributions. For comparison, we've shown the same
$10,000 investment in the Lehman Brothers Municipal Bond Index -- an unmanaged
index that includes approximately 15,000 bonds and is commonly used as a measure
of bond performance.

    during the period ended June 30, 1995.

**  All or a portion of these securities, having an aggregate value of
    $8,896,105 or 1.82% of the Fund's net asset value, have been purchased as
    forward commitments -- that is, the Fund has agreed, on trade date, to take

                   John Hancock Funds - Tax-Exempt Income Fund

(UNAUDITED)
NOTE A  --
ACCOUNTING POLICIES

John Hancock Tax-Exempt Income Fund (the "Fund") is a diversified open-end
investment management company registered under the Investment Company Act of
1940.

   The Trustees have authorized the issuance of two classes of the Fund,
designated as Class A and Class B. The shares of each class represent an
interest in the same portfolio of investments of the Fund and have equal rights
to voting, redemption, 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/service expenses under the terms of a distribution
plan, have exclusive voting rights regarding such distribution plan. Class A
shares are subject to an initial sales charge of up to 4.50% and a 12b-1
distribution plan. Class B shares are subject to a contingent deferred sales
charge and a separate 12b-1 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.

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 transaction. 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.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell municipal bond index and
interest rate futures contracts to hedge against changes in securities prices,
interest rates and other market conditions, or for speculative purposes. The
potential loss incurred by the Fund in writing options on futures is unlimited
and may exceed the amount of the premium received. The Fund's ability to hedge
successfully will depend on the Adviser's ability to predict accurately the
future direction of interest rate changes and other market factors.

   There is no assurance that a liquid market for futures and options will
always exist. In addition, the Fund could be prevented from opening or realizing
the benefits of closing out futures positions because of position limits or
limits on daily price fluctuations imposed by an exchange. The Fund's futures
contracts and options on futures contracts will be traded on a U.S. commodity
exchange or board of trade. The Fund will not engage in a transaction in futures
or option transaction for speculative purposes, if immediately thereafter, the
sum of the initial margin deposits on existing positions and premiums required
to establish these speculative positions exceed 5% of the Funds net assets.

   For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures transactions.

   At June 30, 1995, open positions in financial futures contracts were as
follows:

</TABLE>

   At June 30, 1995, the Fund has deposited in a segregated account $240,000 to
cover margin requirements on open financial futures contracts.

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.

                          NOTES TO FINANCIAL STATEMENTS

                   John Hancock Funds - Tax-Exempt Income Fund

PREMIUM AND DISCOUNT For tax-exempt issues, the Fund amortizes the amount paid
in excess of par value on securities purchased from either the date of purchase
or date of issue to date of sale, maturity or to next call date, if applicable.
The Fund accretes original issue 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. The Fund records market
discount on bonds purchased after April 30, 1993 at the time of disposition.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investment, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $2,374,664 of capital
loss carryforward available, to the extent provided by regulations, to offset
future net realized capital gains. If such carryforward is used by the Fund, no
capital gain distributions will be made. The carryforward expires December 31,
2002.

   Additionally, net capital losses of $858,729 attributable to security
transactions occurring after October 31, 1994 are treated as arising on the
first day (January 1, 1995) of the Fund's current taxable year.

DIVIDENDS, DISTRIBUTIONS, AND INTEREST 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, if any, 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 as explained previously.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution/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 of each class.

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: (a) 0.55% of the first $500,000,000 of the
Fund's average daily net asset value, (b) 0.50% of the next $500,000,000, and
(c) 0.45% of the Fund's average daily net asset value in excess of
$1,000,000,000.

   In the event normal operating expenses of the Fund, exclusive of certain
expenses prescribed by state law, are in excess of the most restrictive state
limit where the Fund is registered to sell shares, the fee payable to the
Adviser will be reduced to the extent of such excess, and the Adviser will make
additional arrangements necessary to eliminate any remaining excess expenses.
The current limits are 2.5% of the first $30,000,000 of the Fund's average daily
net asset value, 2.0% of the next $70,000,000, and 1.5% of the remaining average
daily net asset value. $24,573 of custodian fees have been reduced by balance
credits applied during the period ended June 30, 1995.

   The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly-owned subsidiary of the Adviser. For the period ended June 30,
1995, JH Funds received net sales charges on sales of Class A shares of the Fund

shareholder of Distributors and John Hancock Freedom Securities Corporation and
its subsidiaries, which include Tucker Anthony and Sutro, all of which are
broker-dealers.

   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 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 June 30, 1995,
contingent deferred sales charges received by JH Funds amounted to $4,750.

   In addition, to compensate JH Funds for the services it provides as
distributors of shares of the Fund, the Fund has adopted Distribution Plans with
respect to Class A and Class B shares 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 average daily net
assets to reimburse JH Funds for its distribution and service costs. Up to a
maximum of 0.25% of these 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 Investor Services
Corporation ("Investor Services"), a wholly-owned subsidiary of The Berkeley
Financial Group. The Fund pays transfer agent fees based on the number of
shareholder accounts and certain out-of-pocket expenses.

   Messrs. Edward J. Boudreau, Jr. and Richard S. Scipione are directors 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. Effective with
the fees paid for 1995, 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 will make investments into other John
Hancock Funds, as applicable, to cover its liability with regard to the deferred
compensation. Investments to cover the Fund's deferred compensation liability
will be recorded on the Fund's books as an other asset. The deferred
compensation liability will be marked to market on a periodic basis and income
earned by the investment will be recorded on the Fund's books.
