===================================CEO CORNER===================================

DEAR FELLOW SHAREHOLDERS:

Over the last 12 months, the market's advances were restricted to an
increasingly select group of stocks - primarily in the technology and
communications areas. Even those gains were accompanied by tremendous levels of
daily volatility. But many other stocks, including the household blue-chip
names, fell in response to a tough combination of investor apathy, rising
interest rates and earnings concerns.

In this same period, bonds struggled through one of their worst years in more
than two decades, as the strength of the U.S. economy and the rebound of many
others around the world provoked inflation fears. Though their longer-term
outlook looks brighter, in many instances bond mutual fund investors have
actually lost a little ground or made only slight advances lately.

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

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

While we expect the market to broaden eventually, we also expect more
volatility. More than ever, this type of environment calls for investment
diversification. Since not all parts of your portfolio will perform equally well
all the time, we believe it is important to allocate your assets among different
types of investments and funds that target a variety of market segments. This
strategy, executed under the guidance of a seasoned investment professional,
could provide you with a better chance of both realizing results and weathering
the market's changing conditions.

The market's disappointingly narrow focus has created a widening gap in
investment performance. Keep that in mind as you read the report from your
fund's portfolio management team on the following pages. It's all too easy to
get caught up in the headlines and miss what lies underneath.

Sincerely,

/s/Maureen R. Ford

            Climbing interest rates put a damper on municipal bonds
            -------------------------------------------------------

It has been a rough road for municipal bonds over the last six months, as the
Federal Reserve continued to raise interest rates in an attempt to put the
brakes on inflationary pressures and an overheating economy. Although some
commodity prices such as oil have spiked up, overall inflation still appears to
be under control. Nonetheless, the Federal Reserve's preemptive interest-rate
hikes drove bond prices down during the period.

         Also adding to the downward pressure on municipal bonds was lack of
liquidity in the market. Cash flow into municipal bonds virtually dried up as
investors became disenchanted with falling bond prices and were enticed into the
stock market by higher returns.

Fund performance

Given the market backdrop, municipal bond funds produced disappointing returns
for the period. For the six months ended February 29, 2000, John Hancock
Tax-Free Bond Fund's Class A, Class B and Class C shares returned -0.96%, -1.32%
and -1.38%, respectively, at net asset value. That compared to the -1.31% return
of the average general municipal bond fund, according to Lipper, Inc.1 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 historical
performance information.

duration - of the portfolio. The shorter the duration, the less sensitive the
Fund will be to interest-rate changes. From September through December, we
shortened the Fund's duration, which protected the Fund when rates climbed in
the back half of the year. We began to cautiously push out the Fund's duration
to a neutral position at the start of this year, since, although there likely
are still more rate hikes to come, a goodly portion is already priced into the
bond market.

         On the negative side, the Fund's health-care holdings were a
disappointment. Federal reductions in Medicare and Medicaid reimbursements
turned out to be more severe than industry experts - and even the government -
had anticipated. That has put considerable pressure on the earnings in the
health-care sector - particularly for hospitals, nursing homes and assisted
living centers.

Restructuring the portfolio

It's important to remember, especially in a tough market, that bond prices will
eventually turn around. So it's critical to maintain a long-term investment
perspective and to focus consistently on positioning the Fund for the future.
Given that, we've taken advantage of rising interest rates and the downturn in
the municipal bond market to gradually reshape the portfolio.

         To start, the jump in interest rates allowed us to trade some of our
lower-yielding bonds for higher-yielding ones, improving the overall yield of
the portfolio. Second, we've boosted activity in our ongoing strategy to improve
the Fund's call protection. Call protection guards against a bond's being
redeemed by the issuer for a certain period of time. Good call protection is
important when interest rates are falling, because issuers often try to
refinance their bonds at lower interest rates. If a bond gets "called away," or
redeemed early, then investors are forced to reinvest their money in bonds with
lower yields. Weak bond markets are good for the disciplined investor, because
negative price action often diverts attention from factors like coupon structure
and call protection. It is the perfect time to add long-term value at
inexpensive levels.

         Interest rates move in cyclical phases, and history has demonstrated
that rising rates eventually fall. While rates have recently been on the rise,
overall inflation is still very contained by historical standards. A proactive
Fed has proven to be a boon to bond investors over time. As they say, what goes
up, comes back down. When rates do, the Fund will be well positioned with strong
call protection.

Looking ahead

In the short term, bond investors could be in for a bumpy ride. The Federal
Reserve has clearly

indicated that it is concerned about an overheating economy and budding
inflation. Given that, we believe that the Federal Reserve is likely to stay
focused on interest rates. Concerns about rising rates are likely to keep
investors nervous and the bond market volatile in the near term.

         As for municipal bonds, the technical conditions are improving. For
starters, the supply/demand factors in the municipal market are improving.
Higher rates have reduced overall supply, putting the market in a favorable
technical position. In 1999, new issuance dropped 25%. So far in 2000, it's down
roughly 40%. As demand for municipal bonds begins to pick up, municipal bonds
will be harder to come by, and that is likely to drive prices higher.

         In addition, higher interest rates will eventually put a damper on the
economy's strong growth. When that happens, we are likely to see interest rates
resume their decline. Our discipline is to stay fully invested, and we will also
continue to restructure the portfolio so that it is well positioned when the
market does turn the corner. For now, we plan to continue looking for
opportunities to improve the portfolio's yield and call protection.

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Tax-Free Bond 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 4.50%. 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 carefully before you invest or send money.

Please note that a portion of the Fund's income may be subject to the
Alternative Minimum Tax (AMT). Also note that capital gains are taxable.

Notes to Performance

(1) The Adviser voluntarily reduced a portion of the management fee,
    the Distributor reduced the distribution and service fees and the
    custodian fee was offset with balance credits during the period.
    Without the reduction of expenses and the offset, the average annual
    total return for the one-year, five-year and since inception periods
    for Class A shares would have been (7.98%), 5.91% and 6.34%,
    respectively. The average annual total returns for the one-year,
    five-year and since inception periods for Class B shares would have
    been (8.91%), 5.79% and 5.32%, respectively.The cumulative return since
    inception for Class C shares would have been (5.55%). Without the
    reductions of expenses and the offset, the yield for Class A, Class B
    and Class C shares would have been 5.00%, 4.49% and 4.49%,
    respectively.

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

                    John Hancock Funds - Tax-Free Bond Fund


(Unaudited)

NOTE A -

ACCOUNTING POLICIES

John Hancock Tax-Free Bond 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 Tax-Free Bond Fund (the
"Fund") and John Hancock High Yield Tax-Free Fund. The other series of the Trust
is reported in separate financial statements. The investment objective of the
Fund is to provide as high a level of interest income exempt from federal income
taxes as is consistent with preservation of capital, by investing primarily in
municipal bonds, notes and commercial paper, the interest on which is exempt
from federal income taxes.

         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.

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. For
federal income tax purposes, the Fund has $12,097,340 of capital loss
carryforwards available, to the extent provided by regulations, to offset future
net realized capital gains. To the extent such carryforwards are used by the
Fund, no capital gains distribution will be made. The carryforwards expire as
follows: August 31, 2002 - $6,941,707 and August 31, 2003 - $5,155,633.
Availability of a certain amount of these loss carryforwards which were acquired
on December 6, 1996 in a merger with John Hancock Managed Tax-Exempt Fund, may
be limited in a given 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 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.

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

                    John Hancock Funds - Tax-Free Bond Fund


Code. The Fund records market discount on bonds purchased after April 30, 1993
at time of disposition.

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 relative 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 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 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. The Fund has entered into
a syndicated line of credit agreement with various banks. 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 of up to $500 million,
collectively. Interest is charged to each fund, based on its borrowing. In
addition, a commitment fee based on the average daily unused portion of the line
of credit is allocated among the participating funds. The maximum loan balance
outstanding during the period amounted to $10,964,000. The annualized interest
rate charged during the period ranged from 5.7500% to 6.3125%. At February 29,
2000, there were no outstanding borrowings.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. Buying futures tends to increase the Fund's exposure to
the underlying instrument. Selling futures tends to decrease the Fund's exposure
to the underlying instrument or hedge other Fund instruments. At the time the
Fund 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," equal to a certain percentage of the value of the
financial futures contract being traded. Each day, the futures contract is
valued at the official settlement price on the board of trade or U.S.
commodities exchange on which it trades. Subsequent payments to and from the
broker, known as "variation margin," are made on a daily basis as the market
price of the financial futures contract fluctuates. Daily variation margin
adjustments, arising from this "mark to market," will be recorded by the Fund as
unrealized gains or losses.

         When the contracts are closed, the Fund recognizes a gain or loss.
Risks of entering into futures contracts include the possibility that there may
be an illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. 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
fluctuation imposed by an exchange.

         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 contracts.

         There were no open positions in financial futures contracts for the
period ended February 29, 2000.

OPTIONS The Fund may buy and sell options contracts. Listed options will be
valued at the last quoted sales price on the exchange on which they are
primarily traded. Over-the-counter options will be 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 price
volatility of financial instruments. 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.

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

                    John Hancock Funds - Tax-Free Bond Fund

         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 year-end
Statement of Assets and Liabilities.

         There were no written option transactions for the period ended February
29, 2000.

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.

         The Adviser has voluntarily agreed to limit the Fund's expenses further
to the extent required to prevent expenses from exceeding 0.85%, 1.60% and 1.70%
of the average net assets attributable to Class A, Class B and Class C,
respectively. Accordingly, the reduction in the Advisor's fee amounted to
$96,371 for the period ended February 29, 2000. This limitation may not be
discontinued until December 31, 2000.

         The Fund has an agreement with its custodian bank under which $41,325
of custodian fees have been reduced by balance credits applied during the period
ended February 29, 2000. If the Fund had not entered into this agreement, the
assets not invested, on which these balance credits were earned, could have
produced taxable income.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the period ended
February 29, 2000, net sales charges received with regard to sales of Class A
shares amounted to $130,263. Out of this amount, $4,985 was retained and used
for printing prospectuses, advertising, sales literature and other purposes,
$27,171 was paid as sales commissions to unrelated broker-dealers and $98,107
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 Life Insurance
Company ("JHLICo"), 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 5.00% 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 for providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended February 29,
2000, the contingent deferred sales charges received by JH Funds amounted to
$192,505.

         Class C shares which are redeemed within one year of purchase will be
subject to a 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 for providing distribution related services to
the Fund in connection with the sale of Class C shares. There were no contingent
deferred sales changes received by JH Funds for the period ended February 29,
2000.

         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. JH Funds has agreed to limit the distribution
and service fees pursuant to Class A and Class B plans to 0.15% and 0.90% of the
average daily net assets, respectively. Accordingly, the reduction in the
distribution and service fee amounted to $269,485 and $62,950 for Class A and B,
respectively, for the period ended February 29, 2000. This limitation may not be
discontinued until December 31, 2000. A maximum of 0.25% of such payments may be
service fees as defined by the Conduct Rules of the National Association of
Securities Dealers. Under the Conduct Rules, 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 JHLICo. 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,
accounting and legal 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. Stephen L. Brown, Ms. Maureen R. Ford, Ms. Anne C. Hodsdon and Mr.
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. 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. The investment had no impact on the operations
of the Fund.

DEAR FELLOW SHAREHOLDERS:

Over the last 12 months, the market's advances were restricted to an
increasingly select group of stocks - primarily in the technology and
communications areas. Even those gains were accompanied by tremendous levels of
daily volatility. But many other stocks, including the household blue-chip
names, fell in response to a tough combination of investor apathy, rising
interest rates and earnings concerns.

In this same period, bonds struggled through one of their worst years in more
than two decades, as the strength of the U.S. economy and the rebound of many
others around the world provoked inflation fears. Though their longer-term
outlook looks brighter, in many instances bond mutual fund investors have
actually lost a little ground or made only slight advances lately.

While we expect the market to broaden eventually, we also expect more
volatility. More than ever, this type of environment calls for investment
diversification. Since not all parts of your portfolio will perform equally well
all the time, we believe it is important to allocate your assets among different
types of investments and funds that target a variety of market segments. This
strategy, executed under the guidance of a seasoned investment professional,
could provide you with a better chance of both realizing results and weathering
the market's changing conditions.

The market's disappointingly narrow focus has created a widening gap in
investment performance. Keep that in mind as you read the report from your
fund's portfolio management team on the following pages. It's all too easy to
get caught up in the headlines and miss what lies underneath.

Sincerely,

/s/Maureen R. Ford

                  Inflation fears and rate worries roil bonds
                  -------------------------------------------

Municipal bonds, like most bonds, slumped during the past six months in response
to rising interest rates, inflation fears and flagging demand. Prior to the
beginning of the period, the Federal Reserve had raised interest rates on two
separate occasions to fight potential inflationary pressures resulting from very
strong U.S. economic growth and recovering economies overseas. While inflation
remained virtually non-existent throughout the fall of 1999, inflation concerns
and the prospects for further interest-rate hikes continued to worry bond
investors. They reacted to these worries by pushing bond prices lower and their
yields - which move in the opposite direction from their prices - higher.

         Throughout the period, there weren't any conclusive signs that
inflation was on the rise. But the global economy's increasing strength and
rising oil prices sparked fears that the Fed would continue to push interest
rates a lot higher to contain inflation. Those fears proved warranted when the
Fed did raise interest rates in November 1999 and again in February 2000.
Municipal-bond yields rose accordingly and their prices fell. High-yield bonds
held up relatively well early on, but eventually succumbed to rising-rate
pressures.

In addition to rising interest rates, bonds faced another challenge. They held
little appeal for many investors who were bent on finding fast revenue growth
among high-flying technology stocks. Furthermore, municipals experienced
relatively heavy selling in late 1999 when some

institutional investors, who routinely seek out the most attractive values among
various fixed-income investments, shunned municipals in favor of beaten-down
corporate bonds.

         As bad as it was, the period did contain a silver lining or two. First,
the strong U.S. economy helped boost the tax collections and revenues of
municipal issuers across the country. Second, rising municipal bond yields began
to attract individual investors. For an investor in the top federal tax bracket
(39.6%), a 30-year high-yield municipal bond that yielded 6.5% on February 29,
2000, offered a tax-equivalent yield of approximately 10.7%.

Fund performance

For the six-month period ended February 29, 2000, John Hancock High Yield
Tax-Free Fund's Class A, Class B and Class C shares posted total returns of
- -2.09%, -2.45% and -2.46%,

respectively, at net asset value. By comparison, the average high-yield
municipal bond fund returned -2.90%, according to Lipper, Inc.1 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.

Defensive stance

The Fund's relative outperformance can be attributed to our somewhat defensive
posture during this difficult period. Throughout the period, we maintained a
relatively short duration - a measure of the Fund's sensitivity to interest-rate
changes - that enabled the Fund's share price to fall less when interest rates
rose. In addition, the Fund had a somewhat defensive credit-quality positioning,
with a larger exposure to higher-quality, more liquid high-yielding bonds than
many of its competitors. Many of the lowest-quality, less liquid, high-yielding
bonds proved to be especially vulnerable to unfavorable market conditions.
Finally, our diversified approach worked in our favor. For several years we have
worked to expand the number of holdings within the Fund, so that its performance
isn't overly reliant on the fortunes of one type of bond or a specific security.

         Our focus on premium-coupon bonds was also a plus. Premium coupons pay
interest rates above prevailing market rates and trade at prices that are above
their face - or par - value. Their high levels of income helped cushion them
against price declines caused by rising interest rates. This was especially
helpful in a period when municipal bond prices fell so much that many of them
started to lose eligibility for the more favorable capital gains tax treatment
known

as de minimis. As market conditions subjected more and more bonds to this
obscure tax pitfall it placed further pressure on these bonds that fell outside
of de minimis.

Leaders and laggards

Virtually all of our holdings came under pressure from rising interest rates,
although some hung in better than others. In addition to premium-coupon bonds,
pre-refunded bonds withstood the pressure rather well, although they, too,
posted losses for the period. Pre-refunded bonds have their payments guaranteed
by the funds from a second bond issue, which is usually invested in U.S.
Treasury bonds. On the flip side, health-care bonds as a group were among the
municipal market's worst performers. Concerns about cutbacks in federal Medicare
and Medicaid payments in response to the Balanced Budget Act of 1997 raised
questions about the industry's long-term profitability. In addition, the refusal
of municipal bond insurers to insure lower-quality tiers of the hospital sector
also weighed heavily on the group.

Outlook

In our view, the Federal Reserve policymakers will probably need to push
short-term interest rates higher to contain inflation. Inflation and
interest-rate prospects are likely to worry bond investors. Even though broad
gauges of inflation so far have remained relatively stable, the economy remains
quite strong and the price of oil has risen rapidly. Furthermore, the Fed has
warned about the impact surging stock prices are having on the economy. That's
why we plan to maintain the Fund's current defensive posture, maintaining a
somewhat short duration in the near term.

         Ultimately, however, we believe that investors will begin to anticipate
the final rate hike. When that occurs - probably in the second half of this year
- - we expect that market conditions will improve and bonds will be poised for
better performance. Once we're comfortable that that's the case, we will
consider extending the Fund's duration in order to take advantage of stable or
falling interest rates. We also plan to stay committed to emphasizing the more
liquid, higher-quality bonds within the high-yield market.

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

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock High Yield Tax-Free 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 4.50%. (Prior to May 15, 1995, the maximum applicable sales charge for
Class A shares was 4.75%.) 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 carefully before you invest or send money.

Please note that a portion of the Fund's income may be subject to taxes and some
investors may be subject to the Alternative Minimum Tax (AMT). Also note that
capital gains are taxable.

Notes to Performance

    ended February 29, 2000. Without the balance credits, the average
    annual total return for the one-year period for Class A and Class B
    shares would have been (8.44%) and (9.37%), respectively. The effect to
    the average annual return for the since inception period for Class C
    shares would have been less than 0.01%. Without the balance credits,
    the yields for Class A, Class B and Class C shares would have been
    5.57%, 5.08% and 5.09%, respectively.

                 John Hancock Funds - High Yield Tax-Free Fund


(UNAUDITED)

NOTE A -

ACCOUNTING POLICIES

John Hancock Tax-Free Bond 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 High Yield Tax-Free Fund
(the "Fund") and John Hancock Tax-Free Bond Fund. The other series of the Trust
is reported in separate financial statements. The investment objective of the
Fund is to provide as high a level of interest income exempt from federal income
taxes as is consistent with the preservation of capital, by investing primarily
in municipal bonds, notes and commercial paper, the interest on which is exempt
from federal income taxes.

         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 Board of Trustees,
may be applied differently to each class of shares in accordance with current
regulations of the Securities and Exchange Commission. Shareholders of a class
which bears distribution and service expenses under terms of a distribution plan
have exclusive voting rights regarding 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 Board of 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,
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. For
federal income tax purposes, the Fund has $9,410,341 of capital loss
carryforwards available, to the extent provided by regulations, to offset future
net realized capital gains. To the extent such carryforwards are used by the
Fund, no capital gains distribution will be made. The carryforwards expire as
follows: August 31, 2002 - $2,239,021, August 31, 2003 - $205,838, August 31,
2004 - $3,207,633, August 31, 2005 - $716,668 and August 31, 2006 - $3,041,181.

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 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.

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 time of disposition.

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

                 John Hancock Funds - High Yield Tax-Free 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 readily 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. The Fund has entered into
a syndicated line of credit agreement with various banks. 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 of up to $500 million,
collectively. Interest is charged to each fund, based on its borrowing. In
addition, a commitment fee based on the average daily unused portion of the line
of credit is allocated among the participating funds. The Fund had no borrowing
activity for the period ended February 29, 2000.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts for speculative purposes and/or to hedge against the effects of
fluctuations in interest rates and other market conditions. Buying futures tends
to increase the Fund's exposure to the underlying instrument. Selling futures
tends to decrease the Fund's exposure to the underlying instrument or hedge
other Fund instruments. At the time the Fund 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," equal to a
certain percentage of the value of the financial futures contract being traded.
Each day, the futures contract is valued at the official settlement price on the
board of trade or U.S. commodities exchange on which it trades. Subsequent
payments to and from the broker, known as "variation margin," are made on a
daily basis as the market price of the financial futures contract fluctuates.
Daily variation margin adjustments, arising from this "mark to market," will be
recorded by the Fund as unrealized gains or losses.

         When the contracts are closed, the Fund recognizes a gain or loss.
Risks of entering into futures contracts include the possibility that there may
be an illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. 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
fluctuation imposed by an exchange.

         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 contracts.

         At February 29, 2000, there were no open positions in financial futures
contracts.

OPTIONS The Fund may buy or sell options contracts. 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 changing
security prices. 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.

         At February 29, 2000, there were no open written options contracts.

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) 0.625% of the first $75,000,000 of the Fund's
average daily net asset value, (b) 0.5625% of the next $75,000,000 and (c) 0.50%
of the Fund's average daily net asset value in excess of $150,000,000.

         The Fund has an agreement with its custodian bank under which $14,296
of custodian fees have been reduced by balance credits applied during the period
ended February 29, 2000. If the Fund had not entered into this agreement, the
assets not invested, on which these balance credits were earned, could have
produced taxable income.

         The Fund has a distribution agreement with John Hancock Funds, Inc.
("JH Funds"), a wholly owned subsidiary of the Adviser. For the period ended
February 29, 2000, net sales charges received with regard to sales of Class A
shares amounted to $2,546. Out of this amount, $213 was retained and used for
printing prospectuses, advertising, sales literature and other purposes, $2,249
was paid as sales commissions to unrelated broker-dealers and $84 was paid as
sales commissions to sales personnel of Signator Investors, Inc. ("Signator
Investors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Life Insurance Company ("JHLICo"), 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 5.00% 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 B shares. For the period ended February 29,
2000, contingent deferred sales charges paid to JH Funds amounted to $152,975.

         Class C shares which are redeemed within one year of purchase will be
subject to a 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 February 29, 2000, contingent deferred sales charges paid to JH
Funds amounted to $742.

         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. A maximum of 0.25% of such payments may be service fees as defined by the
Conduct Rules of the National Association of Securities Dealers. Under the
Conduct Rules, 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 JHLICo. The
Fund pays transfer agent fees based on the number of shareholder accounts and
certain out-of-pocket expenses.

and legal services for the Funds. The compensation for the period was at an an
annual rate of less than 0.02% of the average net assets of the Fund.

         Mr. Stephen L. Brown, Ms. Maureen R. Ford, Ms. Anne C. Hodsdon and Mr.
Richard Scipone are trustees and/or officers of the Adviser and/or its
affiliates, as well as Trustees of the Fund. The compensation of unaffiliated

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
