FUND INFORMATION KEY

Concise fund-by-fund descriptions begin on the next page. Each description
provides the following information:

[Clip Art] Goal and strategy The fund's particular investment goals and the
strategies it intends to use in pursuing those goals.

[Clip Art] Main risks The major risk factors associated with the fund.

[Clip Art] Past performance The fund's total return, measured year-by-year and
over time.

[Clip Art] Your expenses The overall costs borne by an investor in the fund,
including sales charges and annual expenses.

JOHN HANCOCK TAX-FREE INCOME FUNDS

These funds seek to offer income that is exempt from federal and, in some cases,
state and local income tax. Each fund has its own strategy and its own risk
profile. Each fund invests at least 80% of assets in municipal securities exempt
from federal (and in some funds, state) income tax as well as the federal
alternative minimum tax. However, a portion of a tax-free fund's income may be
subject to these taxes.

WHO MAY WANT TO INVEST

These funds may be appropriate for investors who:

o are in higher income brackets

o want regular monthly income

o are interested in lowering their income tax burden

o pay California, Massachusetts or New York income tax (state-specific funds)

Tax-free income funds may NOT be appropriate if you:

o are not subject to a high level of state or federal income tax

o are seeking an investment for a tax-deferred retirement account

o are investing for maximum return over a long time horizon

o require absolute stability of your principal

RISKS OF MUTUAL FUNDS

Mutual funds are not bank deposits and are not insured or guaranteed by the
Federal Deposit Insurance Corporation or any other government agency. Because
you could lose money by investing in these funds, be sure to read all risk
disclosure carefully before investing.

THE MANAGEMENT FIRM


All John Hancock tax-free income funds are managed by John Hancock Advisers,
Inc. Founded in 1968, John Hancock Advisers is a wholly owned subsidiary of John
Hancock Financial Services, Inc. and manages more than $30 billion in assets.



                                                                               3

California Tax-Free Income Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks a high level of current income, consistent with
preservation of capital, that is exempt from federal and California personal
income taxes. In pursuing this goal, the fund normally invests at least 80% of
assets in California municipal debt obligations of any maturity. Most of these
securities are investment-grade when purchased, but the fund may invest up to
20% of assets in junk bonds rated BB/Ba and their unrated equivalents.

In managing the portfolio, the management team uses top-down research to assess
general credit trends and identify promising market sectors. To select
securities for long-term investment, the team uses a strategy designed to find
undervalued bonds, based on research into specific municipal issuers, their
creditworthiness and the structure of their bonds.

The management team commonly seeks out revenue bonds, which are repaid from
income tied to specific facilities such as power plants. The team also favors
bonds with limitations on whether they can be called, or redeemed, by the issuer
before maturity. This enables the team to minimize the effect of declining
interest rates on the fund's income.

The fund may make limited use of certain derivatives (investments whose value is
based on indices or other securities), especially in managing its exposure to
interest rate risk.

In abnormal market conditions, the fund may temporarily invest more than 20% of
assets in taxable investment-grade short-term securities. In these and other
cases, the fund might not achieve its goal.

PAST PERFORMANCE

[Clip Art] The graph shows how the fund's total return has varied from year to
year, while the table shows performance over time (along with a broad-based
market index for reference). This information may help provide an indication of
the fund's risks. The average annual figures reflect sales charges; the
year-by-year and index figures do not, and would be lower if they did. All
figures assume dividend reinvestment. Past performance does not indicate future
results.

MAIN RISKS

[Clip Art] The major factor in this fund's performance is interest rates. When
interest rates rise, bond prices generally fall. Generally, an increase in the
fund's average maturity will make it more sensitive to interest rate risk. There
is no limit on the fund's average maturity.

Because the fund invests primarily in California issuers, its performance is
affected by local, state and regional factors. These may include economic or
policy changes, erosion of the tax base, state legislative changes (especially
those regarding taxes) and the possibility of credit problems, such as the 1994
bankruptcy of Orange County.

The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. In general, lower-rated bonds have higher credit risks. If
certain sectors or investments do not perform as the fund expects, it could
under-perform its peers or lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

o   Revenue bonds could be downgraded or go into default if revenues from their
    underlying facilities decline, causing the fund to lose money.
o   Junk bonds could make the fund more sensitive to market or economic shifts.
o   Certain derivatives could produce disproportionate losses.
o   In a down market, certain securities and derivatives could become harder to
    value or to sell at a fair price.

High Yield Tax-Free Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks a high level of current income that is largely exempt
from federal income tax consistent with preservation of capital. In pursuing
this goal, the fund normally invests at least 80% of assets in tax-exempt
municipal debt obligations of any maturity with credit ratings from A to BB/Ba
and their unrated equivalents. The fund may also invest up to 5% of assets in
bonds rated as low as CC/Ca and their unrated equivalents. Bonds that are in or
below the BB/Ba category are considered junk bonds.

In managing the portfolio, the management team uses top-down research to assess
general credit trends and identify promising market sectors. To select
securities for long-term investment, the team uses a strategy designed to find
undervalued bonds, based on research into specific municipal issuers, their
creditworthiness and the structure of their bonds.

The management team commonly seeks out revenue bonds, which are repaid from
income tied to specific facilities such as power plants. The team also favors
bonds with limitations on whether they can be called, or redeemed, by the issuer
before maturity. This enables the team to minimize the effect of declining
interest rates on the fund's income.

The fund may make limited use of certain derivatives (investments whose value is
based on indices or other securities), especially in managing its exposure to
interest rate risk.

In abnormal market conditions, the fund may temporarily invest more than 20% of
assets in taxable investment-grade short-term securities. In these and other
cases, the fund might not achieve its goal.

MAIN RISKS

[Clip Art] The major factors in this fund's performance are interest rates and
credit risk. When interest rates rise, bond prices generally fall. Generally, an
increase in the fund's average maturity will make it more sensitive to interest
rate risk. There is no limit on the fund's average maturity.

Because their issuers are often in relatively weak financial health, junk bonds
could make the fund more sensitive to market or economic shifts, and to the risk
of default of a particular bond. In general, investors should expect
fluctuations in share price, yield and total return that are above average for
bond funds.

The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. If certain sectors or investments do not perform as the fund
expects, it could underperform its peers or lose money.

To the extent that the fund invests in securities with additional risks, those
risks could increase volatility or reduce performance:

o   Revenue bonds could be downgraded or go into default if revenues from their
    underlying facilities decline, causing the fund to lose money.
o   If the fund invests heavily in securities from a given state or region, its
    performance could be disproportionately affected by political or demographic
    factors in that state or region.
o   Certain derivatives could produce disproportionate losses.
o   In a down market, certain securities and derivatives could become harder to
    value or to sell at a fair price.

Massachusetts Tax-Free Income Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks a high level of current income, consistent with
preservation of capital, that is exempt from federal and Massachusetts personal
income taxes.

In pursuing its goal, the fund normally invests at least 80% of assets in
securities of any maturity exempt from Massachusetts personal income taxes. Most
of these securities have credit ratings of A or higher when purchased, but the
fund may invest up to 33.3% of assets in securities rated as low as BB/Ba and
their unrated equivalents. Bonds that are in or below the BB/Ba category are
considered junk bonds.

In managing the portfolio, the management team uses top-down research to assess
general credit trends and identify promising market sectors. To select
securities for long-term investment, the team uses a strategy designed to find
undervalued bonds, based on research into specific municipal issuers, their
creditworthiness and the structure of their bonds.

The management team commonly seeks out revenue bonds, which are repaid from
income tied to specific facilities such as power plants. The team also favors
bonds with limitations on whether they can be called, or redeemed, by the issuer
before maturity. This enables the team to minimize the effect of declining
interest rates on the fund's income. The fund is non-diversified and may invest
more than 5% of assets in securities of a single issuer.

The fund may make limited use of certain derivatives (investments whose value is
based on indices or other securities), especially in managing its exposure to
interest rate risk.

In abnormal market conditions, the fund may temporarily invest more than 20% of
assets in taxable investment-grade short-term securities. In these and other
cases, the fund might not achieve its goal.

MAIN RISKS

[Clip Art] The major factor in this fund's performance is interest rates. When
interest rates rise, bond prices generally fall. Generally, an increase in the
fund's average maturity will make it more sensitive to interest rate risk. There
is no limit on the fund's average maturity.

Because the fund invests primarily in Massachusetts issuers, its performance is
affected by local, state and regional factors. These may include economic or
policy changes, erosion of the tax base, state legislative changes (especially
those affecting taxes) and the possibility of credit problems.

The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. In general, lower-rated bonds have higher credit risks. If
certain sectors or investments do not perform as the fund expects, it could
underperform its peers or lose money.

To the extent that the fund invests in securities with additional risks, those
risks could increase volatility or reduce performance:

o   Revenue bonds could be downgraded or go into default if revenues from their
    underlying facilities decline, causing the fund to lose money.
o   If the fund invests heavily in a single issuer, its performance could suffer
    significantly from adverse events affecting that issuer.
o   Junk bonds could make the fund more sensitive to market or economic shifts.
o   Certain derivatives could produce disproportionate losses.
o   In a down market, certain securities and derivatives could become harder to
    value or to sell at a fair price.

Tax-Free Bond Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks as high a level of interest income exempt from federal
income tax as is consistent with preservation of capital. In pursuing this goal,
the fund normally invests at least 80% of assets in tax-exempt municipal debt
obligations of any maturity. Most of these bonds are investment-grade when
purchased, but the fund may also invest up to 35% of assets in junk bonds rated
BB/Ba or B and their unrated equivalents.

In managing the portfolio, the management team uses top-down research to assess
general credit trends and identify promising market sectors. To select
securities for long-term investment, the management team uses a strategy
designed to find undervalued bonds, based on research into specific municipal
issuers, their creditworthiness and the structure of their bonds.

The management team commonly seeks out revenue bonds, which are repaid from
income tied to specific facilities such as power plants. The fund may invest up
to 25% of assets in private activity bonds.

The management team also favors bonds with limitations on whether they can be
called, or redeemed, by the issuer before maturity. This enables the team to
minimize the effect of declining interest rates on the fund's income.

The fund may make limited use of certain derivatives (investments whose value is
based on indices or other securities), especially in managing its exposure to
interest rate risk.

In abnormal market conditions, the fund may temporarily invest more than 20% of
assets in taxable investment-grade short-term securities. In these and other
cases, the fund might not achieve its goal.

MAIN RISKS

[Clip Art] The major factors in this fund's performance are interest rates and
credit risk. When interest rates rise, bond prices generally fall. Generally, an
increase in the fund's average maturity will make it more sensitive to interest
rate risk. There is no limit on the fund's average maturity.

Junk bonds may make the fund more sensitive to market or economic shifts. The
fund could lose money if any bonds it owns are downgraded in credit rating or go
into default. If certain sectors or investments do not perform as the fund
expects, it could underperform its peers or lose money.

To the extent that the fund invests in other securities with additional risks,
those risks could increase volatility or reduce performance:

o   If the fund invests heavily in securities from a given state or region, its
    performance could be disproportionately affected by political or demographic
    factors in that state or region.

o   Revenue bonds could be downgraded or go into default if revenues from their
    underlying facilities decline, causing the fund to lose money.

o   Certain derivatives could produce disproportionate losses.

o   In a down market, certain securities and derivatives could become harder to
    value or to sell at a fair price.

YOUR EXPENSES

[Clip Art] Transaction expenses are charged directly to your account. Operating
expenses are paid from the fund's assets, and therefore are paid by shareholders
indirectly.

CHOOSING A SHARE CLASS

Each share class has its own cost structure, including a Rule 12b-1 plan that
allows it to pay fees for the sale, distribution and service of its shares. Your
financial representative can help you decide which share class is best for you.

- --------------------------------------------------------------------------------
Class A
- --------------------------------------------------------------------------------


o   A front-end sales charge, as described at right.


o   Distribution and service (12b-1) fees of 0.15% for California Tax-Free
    Income and Tax-Free Bond, 0.25% for High Yield Tax-Free and 0.30% for
    Massachusetts Tax-Free Income and New York Tax-Free Income.

- --------------------------------------------------------------------------------
Class B
- --------------------------------------------------------------------------------

o   No front-end sales charge; all your money goes to work for you right away.

o   Distribution and service (12b-1) fees of 1.00% (0.90% for California
    Tax-Free Income and Tax-Free Bond).

o   A deferred sales charge, as described at right.

o   Automatic conversion to Class A shares after eight years, thus reducing
    future annual expenses.

- --------------------------------------------------------------------------------
Class C
- --------------------------------------------------------------------------------


o   A front-end sales charge, as described at right.


o   Distribution and service (12b-1) fees of 1.00%.

o   A 1.00% contingent deferred sales charge on shares sold within one year of
    purchase.

o   No automatic conversion to Class A shares, so annual expenses continue at
    the Class C level throughout the life of your investment.

For actual past expenses of each share class, see the fund-by-fund information
earlier in this prospectus.

Because 12b-1 fees are paid on an ongoing basis, they may cost shareholders more
than other types of sales charges.

Investors purchasing $1 million or more of Class B or Class C shares may want to
consider the lower operating expenses of Class A shares.


Your broker receives a percentage of these sales charges and fees. In addition,
John Hancock Funds may pay significant compensation out of its own resources to
your broker.


Your broker or agent may charge you a fee to effect transactions in fund shares.

HOW SALES CHARGES ARE CALCULATED


Class A and Class C Sales charges are as follows:

Investments of $1 million or more Class A and Class C shares are available with
no front-end sales charge. However, there is a contingent deferred sales charge
(CDSC) on any Class A shares sold within one year of purchase, as follows:


- --------------------------------------------------------------------------------
CDSC on $1 million+ investments
- --------------------------------------------------------------------------------
                                           CDSC on shares
Your investment                            being sold
First $1M - $4,999,999                     1.00%
Next $1 - $5M above that                   0.50%
Next $1 or more above that                 0.25%

For purposes of this CDSC, all purchases made during a calendar month are
counted as having been made on the first day of that month.

The CDSC is based on the lesser of the original purchase cost or the current
market value of the shares being sold, and is not charged on shares you acquired
by reinvesting your dividends. To keep your CDSC as low as possible, each time
you place a request to sell shares we will first sell any shares in your account
that are not subject to a CDSC.


Class B Shares are offered at their net asset value per share, without any
initial sales charge.

Class B and Class C A CDSC may be charged if you sell Class B or Class C shares
within a certain time after you bought them, as described in the tables below.
There is no CDSC on shares acquired through reinvestment of dividends. The CDSC
is based on the original purchase cost or the current market value of the shares
being sold, whichever is less. The CDSCs are as follows:


- --------------------------------------------------------------------------------
Class B deferred charges
- --------------------------------------------------------------------------------
Years after                             CDSC on shares

1st year                                5.00%
2nd year                                4.00%
3rd year                                3.00%
4th year                                3.00%
5th year                                2.00%
6th year                                1.00%
After 6th year                          none

After 1st year                          none

For purposes of these CDSCs, all purchases made during a calendar month are
counted as having been made on the first day of that month.


14 YOUR ACCOUNT
<PAGE>

CDSC calculations are based on the number of shares involved, not on the value
of your account. To keep your CDSC as low as possible, each time you place a
request to sell shares we will first sell any shares in your account that carry
no CDSC. If there are not enough of these to meet your request, we will sell
those shares that have the lowest CDSC.

- --------------------------------------------------------------------------------
SALES CHARGE REDUCTIONS AND WAIVERS

Reducing your Class A sales charges There are several ways you can combine
multiple purchases of Class A shares of John Hancock funds to take advantage of
the breakpoints in the sales charge schedule. The first three ways can be
combined in any manner.

o   Accumulation Privilege -- lets you add the value of any Class A shares you
    already own to the amount of your next Class A investment for purposes of
    calculating the sales charge. Retirement plans investing $1 million in Class
    B shares may add that value to Class A purchases to calculate charges.
o   Letter of Intention -- lets you purchase Class A shares of a fund over a
    13-month period and receive the same sales charge as if all shares had been
    purchased at once.
o   Combination Privilege -- lets you combine Class A shares of multiple funds
    for purposes of calculating the sales charge.

To utilize: complete the appropriate section of your application, or contact
your financial representative or Signature Services, or consult the SAI (see the
back cover of this prospectus).

Group Investment Program A group may be treated as a single purchaser under the
accumulation and combination privileges. Each investor has an individual
account, but the group's investments are lumped together for sales charge
purposes, making the investors potentially eligible for reduced sales charges.
There is no charge or obligation to invest (although initial investments must
total at least $250), and individual investors may close their accounts at any
time.

To utilize: contact your financial representative or Signature Services to find
out how to qualify, or consult the SAI (see the back cover of this prospectus).

CDSC waivers As long as Signature Services is notified at the time you sell, the
CDSC for each share class will generally be waived in the following cases:

o   to make payments through certain systematic withdrawal plans
o   to make certain distributions from a retirement plan
o   because of shareholder death or disability

To utilize: if you think you may be eligible for a CDSC waiver, contact your
financial representative or Signature Services, or consult the SAI (see the back
cover of this prospectus).

Reinstatement privilege If you sell shares of a John Hancock fund, you may
reinvest some or all of the proceeds in the same share class of any John Hancock
fund within 120 days without a sales charge, as long as Signature Services is
notified before you reinvest. If you paid a CDSC when you sold your shares, you
will be credited with the amount of the CDSC. All accounts involved must have
the same registration.

To utilize: contact your financial representative or Signature Services.

Waivers for certain investors Class A shares may be offered without front-end
sales charges or CDSCs to various individuals and institutions, including:

o   selling brokers and their employees and sales representatives
o   financial representatives utilizing fund shares in fee-based investment
    products under signed agreement with John Hancock Funds
o   fund trustees and other individuals who are affiliated with these or other
    John Hancock funds
o   individuals transferring assets from an employee benefit plan into a John
    Hancock fund
o   certain John Hancock insurance contract holders (one-year CDSC usually
    applies)
o   participants in certain retirement plans with at least 100 eligible
    employees (one-year CDSC applies)


Class C shares may be offered without front-end sales charges to various
individuals and institutions, including certain retirement plans.


To utilize: if you think you may be eligible for a sales charge waiver, contact
Signature Services or consult the SAI (see the back cover of this prospectus).

Selling shares in writing In certain circumstances, you will need to make your
request to sell shares in writing. You may need to include additional items with
your request, unless they were previously provided to Signature Services and are
still accurate. These items are shown in the table below. You may also need to
include a signature guarantee, which protects you against fraudulent orders. You
will need a signature guarantee if:

o  your address of record has changed within the past 30 days
o  you are selling more than $100,000 worth of shares
o  you are requesting payment other than by a check mailed to the address of
   record and payable to the registered owner(s)

You will need to obtain your signature guarantee from a member of the Signature
Guarantee Medallion Program. Most brokers and securities dealers are members of
this program. A notary public CANNOT provide a signature guarantee.

TRANSACTION POLICIES

Valuation of shares The net asset value per share (NAV) for each fund and class
is determined each business day at the close of regular trading on the New York
Stock Exchange (typically 4 P.M. Eastern Time). The funds use market prices in
valuing portfolio securities, but may use fair-value estimates if reliable
market prices are unavailable.

Buy and sell prices When you buy shares, you pay the NAV plus any applicable
sales charges, as described earlier. When you sell shares, you receive the NAV
minus any applicable deferred sales charges.

Execution of requests Each fund is open on those days when the New York Stock
Exchange is open, typically Monday through Friday. Buy and sell requests are
executed at the next NAV to be calculated after Signature Services receives your
request in good order.


At times of peak activity, it may be difficult to place requests by phone.
During these times, consider using EASI-Line, accessing www.jhfunds.com, or
sending your request in writing.


In unusual circumstances, any fund may temporarily suspend the processing of
sell requests, or may postpone payment of proceeds for up to three business days
or longer, as allowed by federal securities laws.

Telephone transactions For your protection, telephone requests may be recorded
in order to verify their accuracy. Also for your protection, telephone
redemption transactions are not permitted on accounts whose names or addresses
have changed within the past 30 days. Proceeds from telephone transactions can
only be mailed to the address of record.

Exchanges You may exchange shares of one John Hancock fund for shares of the
same class of any other, generally without paying any additional sales charges.
The registration for both accounts involved must be identical. Class B and Class
C shares will continue to age from the original date and will retain the same
CDSC rate. However, if the new fund's CDSC rate is higher, then the rate will
increase. A CDSC rate that has increased will drop again with a future exchange
into a fund with a lower rate.

To protect the interests of other investors in the fund, a fund may cancel the
exchange privileges of any parties that, in the opinion of the fund, are using
market timing strategies or making more than seven exchanges per owner or
controlling party per calendar year. A fund may also refuse any exchange order.
A fund may change or cancel its exchange policies at any time, upon 60 days'
notice to its shareholders.

Certificated shares Most shares are electronically recorded. If you wish to have
certificates for your shares, please write to Signature Services. Certificated
shares can only be sold by returning the certificates to Signature Services,
along with a letter of instruction or a stock power and a signature guarantee.

Sales in advance of purchase payments When you place a request to sell shares
for which the purchase money has not yet been collected, the request will be
executed in a timely fashion, but the fund will not release the proceeds to you
until your purchase payment clears. This may take up to ten business days after
the purchase.

Eligibility by state You may only invest in, or exchange into, fund shares
legally available in your state.

- --------------------------------------------------------------------------------
DIVIDENDS AND ACCOUNT POLICIES

Account statements In general, you will receive account statements as follows:

o  after every transaction (except a dividend reinvestment) that affects your
   account balance
o  after any changes of name or address of the registered owner(s)
o  in all other circumstances, every quarter

Every year you should also receive, if applicable, a Form 1099 tax information
statement, mailed by January 31.

Dividends The funds generally declare dividends daily and pay them monthly.
Capital gains, if any, are distributed annually, typically after the end of a
fund's fiscal year. Most of these funds' dividends are income dividends. Your
dividends begin accruing the day after payment is received by the fund and
continue through the day your shares are actually sold.

Dividend reinvestments Most investors have their dividends reinvested in
additional shares of the same fund and class. If you choose this option, or if
you do not indicate any choice, your dividends will be reinvested on the
dividend record date. Alternatively, you can choose to have a check for your
dividends mailed to you. However, if the check is not deliverable, your
dividends will be reinvested.


                                                                 YOUR ACCOUNT 19

Taxability of dividends As long as a fund meets the requirements for being a
tax-qualified regulated investment company, which each fund has in the past and
intends to in the future, it pays no federal income tax on the earnings it
distributes to shareholders.

Each fund intends to meet certain federal tax requirements so that distributions
of the tax-exempt interest it earns may be treated as "exempt-interest
dividends." However, any portion of exempt-interest dividends attributable to
interest on private activity bonds may increase certain shareholders'
alternative minimum tax.

Dividends from a fund's short-term capital gains are taxable as ordinary income.
Dividends from a fund's long-term capital gains are taxable at a lower rate.
Whether gains are short-term or long-term depends on the fund's holding period.
Taxable dividends paid in January may be taxable as if they had been paid the
previous December.

The state tax-free income funds intend to comply with certain state tax
requirements so that their income dividends will generally be exempt from state
and local personal income taxes in the applicable state. Dividends of the other
tax-free income funds are generally not exempt from state and local income
taxes.

The tax information that is mailed to you every January details your dividends
and their federal tax category, although you should verify your tax liability
with your tax professional.

Taxability of transactions Any time you sell or exchange shares, it is
considered a taxable event for you. Depending on the purchase price and the sale
price of the shares you sell or exchange, you may have a gain or a loss on the
transaction. You are responsible for any tax liabilities generated by your
transactions.

Small accounts (non-retirement only) If you draw down a non-retirement account
so that its total value is less than $1,000, you may be asked to purchase more
shares within 30 days. If you do not take action, your fund may close out your
account and mail you the proceeds. Alternatively, Signature Services may charge
you $10 a year to maintain your account. You will not be charged a CDSC if your
account is closed for this reason, and your account will not be closed if its
drop in value is due to fund performance or the effects of sales charges.



- --------------------------------------------------------------------------------
ADDITIONAL INVESTOR SERVICES

Monthly Automatic Accumulation Program (MAAP) MAAP lets you set up regular
investments from your paycheck or bank account to the John Hancock fund(s) of
your choice. You determine the frequency and amount of your investments, and you
can terminate your program at any time. To establish:

o  Complete the appropriate parts of your account application.
o  If you are using MAAP to open an account, make out a check ($25 minimum) for
   your first investment amount payable to "John Hancock Signature Services,
   Inc." Deliver your check and application to your financial representative or
   Signature Services.

Systematic withdrawal plan This plan may be used for routine bill payments or
periodic withdrawals from your account. To establish:

o  Make sure you have at least $5,000 worth of shares in your account.
o  Make sure you are not planning to invest more money in this account (buying
   shares during a period when you are also selling shares of the same fund is
   not advantageous to you, because of sales charges).
o  Specify the payee(s). The payee may be yourself or any other party, and there
   is no limit to the number of payees you may have, as long as they are all on
   the same payment schedule.
o  Determine the schedule: monthly, quarterly, semi-annually, annually or in
   certain selected months.
o  Fill out the relevant part of the account application. To add a systematic
   withdrawal plan to an existing account, contact your financial representative
   or Signature Services.

Retirement plans John Hancock Funds offers a range of retirement plans,
including traditional, Roth and Education IRAs, SIMPLE plans, SEPs, 401(k) plans
and other pension and profit-sharing plans. Using these plans, you can invest in
any John Hancock fund with a low minimum investment of $250 or, for some group
plans, no minimum investment at all. Because of certain tax implications,
tax-free income funds are not appropriate investments for qualified retirement
plans.

ORGANIZATION OF THE FUND

The Fund is a series of the Trust,  an open-end  investment  management  company
organized as a Massachusetts  business trust under the laws of The  Commonwealth
of Massachusetts.  Prior to July 1, 1996, the Massachusetts Tax-Free Income Fund
was known as the Massachusetts Portfolio.


John Hancock Advisers, Inc. (the "Adviser") is the Fund's investment adviser.
The Adviser is an indirect wholly-owned subsidiary of John Hancock Life
Insurance Company (formerly John Hancock Mutual Life Insurance Company) (the
"Life Company"), a Massachusetts life insurance company chartered in 1862, with
national headquarters at John Hancock Place, Boston, Massachusetts. The Life
Company is wholly owned by John Hancock Financial Services, Inc., a Delaware
Corporation, organized in February, 2000.


INVESTMENT OBJECTIVE AND POLICIES

The following  information  supplements the discussion of the Fund's  investment
objective and policies discussed in the Prospectus.  Appendix A contains further
information describing investment risks. The investment objective of the Fund is
not fundamental and may be changed by the Trustees without shareholder approval.
There is no assurance that the Fund will achieve its investment objective.

The Fund's objective is to provide investors with current income excludable from
gross income for Federal income tax purposes and exempt from the personal income
tax of Massachusetts.  The Fund seeks to provide the maximum level of tax-exempt
income that is consistent with preservation of capital.

Non-Diversification.  The Fund is registered as a  "non-diversified"  investment
company, permitting the Adviser to invest more than 5% of the assets of the Fund
in the obligations of any one issuer.  Since a relatively high percentage of the
Fund's assets may be invested in the obligations of a limited number of issuers,
the  value  of Fund  shares  may be more  susceptible  to any  single  economic,
political  or  regulatory  event  than the  shares of a  diversified  investment
company.

Additional  Risks.  Securities  in which the Fund may invest are  subject to the
provisions of  bankruptcy,  insolvency  and other laws  affecting the rights and
remedies of creditors,  such as the Federal  Bankruptcy  Code, and laws, if any,
which may be  enacted  by  Congress  or, as the case may be,  the  Massachusetts
legislature extending the time for payment of principal or interest, or both, or
imposing other constraints upon enforcement of such  obligations.  There is also
the possibility that, as a result of litigation or other  conditions,  the power
or ability of any one or more issuers to pay when due  principal of and interest
on their tax-exempt securities may be materially affected.

From time to time, proposals have been introduced before Congress which would
adversely affect the Federal income tax consequences of holding tax-exempt
securities. Federal tax legislation enacted primarily during the 1980's limits
the types and amounts of tax-exempt securities issuable for certain purposes,
especially industrial development bonds and other types of "private activity"
bonds. Such limits may affect the future supply and yields of these types of
tax-exempt securities. Further proposals limiting the issuance of tax-exempt
securities may well be introduced in the future. If it appeared that the
availability of tax-exempt securities for investment by the Fund and the value
of the Fund's investments could be materially affected by such changes in law,
the Trustees would reevaluate the Fund's investment objective and policies and
consider changes in the structure of the Fund or its dissolution.

                                       2
<PAGE>


All of the investments of the Fund will be made in:

         (1)      tax-exempt  securities which at the time of purchase are rated
                  BB or better by Standard & Poor's  Ratings Group  ("S&P"),  or
                  Fitch  Investors  Services,  Inc.  ("Fitch")  or Ba by Moody's
                  Investors Service, Inc. ("Moody's").  Alternatively, the bonds
                  may  be  unrated  but  considered  by  the  Adviser  to  be of
                  comparable  quality.  Not more than  one-third  of the  Fund's
                  total assets will be invested in Tax-Exempt  Bonds rated lower
                  than A or determined to be of comparable quality.

         (2)      Notes of  issuers  having an issue of  outstanding  tax-exempt
                  securities  rated at least A by S&P,  Moody's or by Fitch,  or
                  notes which are  guaranteed  by the U.S.  Government  or rated
                  MIG-1  or  MIG-2  by  Moody's,  or  unrated  notes  which  are
                  determined to be of comparable quality by the Adviser.

         (3)      Obligations issued or guaranteed by the U.S.  Government,  its
                  agencies or  instrumentalities.  Some obligations issued by an
                  agency or  instrumentality  may be supported by the full faith
                  and credit of the U.S. Treasury, while others may be supported
                  only  by  the  credit  of the  particular  Federal  agency  or
                  instrumentality.

         (4)      Commercial  paper which is rated A-1 or A-2 by S&P, P-1 or P-2
                  by Moody's,  or at least F-1 by Fitch,  or which is not rated,
                  but is considered by the Adviser to be of comparable  quality;
                  obligations  of  banks  with $1  billion  of  assets  and cash
                  equivalents,   including  certificates  of  deposit,   bankers
                  acceptances and repurchase  agreements.  Ratings of A-2 or P-2
                  on  commercial  paper  indicate a strong  capacity  for timely
                  payment, although the relative degree of safety is not as high
                  as for  issuers  designated  A-1 or P-1.  Appendix  B contains
                  further information about ratings.

Tax-Exempt  Securities.  These  are debt  securities  issued  by or on behalf of
states,  territories  and  possessions  of the United States and the District of
Columbia and their political  subdivisions,  agencies or instrumentalities,  the
interest  on which is  excludable  from  gross  income  for  Federal  income tax
purposes,  without regard to whether the interest  income thereon is exempt from
the personal income tax of any state.

Tax-exempt  securities are issued to obtain funds for various  public  purposes,
including the construction of a wide range of public facilities such as bridges,
highways,  housing,  hospitals, mass transportation,  schools, streets and water
and sewer works.  Other public purposes for which  tax-exempt  securities may be
issued include the refunding of outstanding  obligations or obtaining  funds for
general operating expenses.

In addition,  certain types of "private  activity bonds" may be issued by public
authorities to finance privately  operated housing  facilities and certain local
facilities for water supply, gas, electricity, sewage or solid waste disposal or
student loans, or to obtain funds to lend to public or private  institutions for
the  construction  of  facilities  such as  educational,  hospital  and  housing
facilities.  Such private activity bonds are included within the term tax-exempt
securities  if the  interest  paid  thereon is  excluded  from gross  income for
Federal income tax purposes.

The interest income on certain private activity bonds (including the Fund's
distributions to its shareholders attributable to such interest) may be treated
as a tax preference item under the Federal alternative minimum tax. The Fund
will not include tax-exempt securities generating this income for purposes of
measuring compliance with the 80% fundamental investment policy described in the
Prospectus.

                                       3
<PAGE>


Other types of private  activity  bonds,  the proceeds of which are used for the
construction,  equipment, repair or improvement of privately operated industrial
or commercial facilities, may also constitute tax-exempt securities, but current
Federal tax law places substantial limitations on the size of such issues.

Yields.  The  yields or  returns  on  tax-exempt  bonds  depend on a variety  of
factors,  including  general  money market  conditions,  effective  marginal tax
rates,  the  financial  condition  of  the  issuer,  general  conditions  of the
tax-exempt securities market, the size of a particular offering, the maturity of
the  obligation  and the rating (if any) of the issue.  The  ratings of Moody's,
Fitch and S&P represent  their opinions as to the quality of various  tax-exempt
securities which they undertake to rate. It should be emphasized,  however, that
ratings  are  not  absolute  standards  of  quality.  Consequently,   tax-exempt
securities  with the same maturity and interest rate with different  ratings may
have the same  yield.  Yield  disparities  may occur for  reasons  not  directly
related to the investment  quality of particular  issues or the general movement
of  interest  rates,  due to such  factors as changes in the  overall  demand or
supply of various  types of tax-exempt  securities or changes in the  investment
objectives of investors.

The market value of debt securities which carry no equity participation  usually
reflects yields  generally  available on securities of similar quality and type.
When such yields decline,  the market value of a portfolio  already  invested at
higher yields can be expected to rise if such  securities are protected  against
early call. In general,  in selecting  securities,  the portfolio manager of the
Fund intends to seek protection against early call. Similarly,  when such yields
increase,  the market value of a portfolio  already invested at lower yields can
be  expected to decline.  The Fund may invest in debt  securities  which sell at
substantial  discounts  from par.  These  securities are low coupon bonds which,
during periods of high interest rates,  because of their lower  acquisition cost
tend to sell on a yield basis approximating current interest rates.

Municipal  Bonds.  Municipal  bonds  generally are  classified as either general
obligation  bonds or revenue bonds.  General  obligation bonds are backed by the
credit of an  issuer  having  taxing  power and are  payable  from the  issuer's
general unrestricted  revenues.  Their payment may depend on an appropriation of
the issuer's legislative body. Revenue bonds, by contrast, are payable only from
the revenues derived from a particular  project,  facility or a specific revenue
source.
They are not generally payable from the unrestricted revenues of the issuer.

"Moral  Obligation"  Bonds.  With "moral  obligation"  bonds,  the Fund does not
currently  intend  to  invest  in  so-called  "moral  obligation"  bonds,  where
repayment  is backed by a moral  commitment  of an entity other than the issuer,
unless  the  credit  of  the  issuer  itself,   without  regard  to  the  "moral
obligation,"  meets the investment  criteria  established for investments by the
Fund.

Tax-Exempt Notes. Tax-exempt notes generally are used to provide for short-term
capital needs and generally have maturities of one year or less. Tax-exempt
notes include:

Project Notes. Project notes are backed by an agreement between a local issuing
agency and the Federal Department of Housing and Urban Development ("HUD") and
carry a United States Government guarantee. These notes provide financing for a
wide range of financial assistance programs for housing, redevelopment, and
related needs (such as low-income housing programs and urban renewal programs).
Although they are the primary obligations of the local public housing agencies
or local urban renewal agencies, the HUD agreement provides for the additional
security of the full faith and credit of the United States Government. Payment
by the United States pursuant to its full faith and credit obligation does not
impair the tax-exempt character of the income from Project Notes.

                                       4
<PAGE>


Tax-Anticipation  Notes.  Tax  anticipation  notes are issued to finance working
capital needs of municipalities.  Generally,  they are issued in anticipation of
various tax revenues,  such as income,  sales,  use and business taxes,  and are
specifically payable from these particular future tax revenues.

Revenue Anticipation Notes. Revenue anticipation notes are issued in expectation
of receipt of  specific  types of  revenue,  other than  taxes,  such as federal
revenues available under Federal Revenue Sharing Programs.

Bond Anticipation  Notes. Bond anticipation  notes are issued to provide interim
financing  until  long-term bond financing can be arranged.  In most cases,  the
long-term bonds then provide the funds for the repayment of the notes.

Construction   Loan  Notes.   Construction   loan  notes  are  sold  to  provide
construction financing.  Permanent financing,  the proceeds of which are applied
to the payment of construction loan notes, is sometimes provided by a commitment
by  the  Government   National  Mortgage   Association  to  purchase  the  loan,
accompanied  by a commitment  by the Federal  Housing  Administration  to insure
mortgage  advances  thereunder.  In  other  instances,  permanent  financing  is
provided by the commitments of banks to purchase the loan.

Commercial  Paper.  Issues of commercial paper typically  represent  short-term,
unsecured, negotiable promissory notes. These obligations are issued by agencies
of state and local  governments  to finance  seasonal  working  capital needs of
municipalities  or to provide interim  construction  financing and are paid from
general  revenues of  municipalities  or are refinanced  with long-term debt. In
most cases, tax- exempt commercial paper is backed by letters of credit, lending
agreements,  note  repurchase  agreements  or other credit  facility  agreements
offered by banks or other institutions.

A-1      Ratings As Investment Criteria.

Lower Rated High Yield "High Risk" Debt Obligations. The Fund may invest in high
yielding,  fixed income  securities  rated below Baa by Moody's or BBB by S&P or
Fitch or which are unrated but are considered by the Adviser to be of comparable
quality.  Ratings are based largely on the historical financial condition of the
issuer.  Consequently,  the rating  assigned to any  particular  security is not
necessarily a reflection of the issuer's current financial condition,  which may
be better or worse  than the rating  would  indicate.  Bonds  rated BB or Ba are
generally referred to as junk bonds.
See "Appendix B" attached hereto.

The values of lower-rated securities and those which are unrated but which are
considered by the Adviser to be of comparable quality generally fluctuate more
than those of high-rated securities. These securities involve greater price
volatility and risk of loss of principal and income. In addition, the lower
rating reflects a greater possibility of an adverse change in financial
condition affecting the ability of the issuer to make payments of interest and
principal. The market price and liquidity of lower-rated securities generally
respond to short-term market developments to a greater extent than for higher
rated securities, because these developments are perceived to have a more direct
relationship to the issuer's ability to meet its ongoing debt obligations.
Although the Adviser seeks to minimize these risks through diversification,
investment analysis and attention to current developments in interest rates and
economic conditions, there can be no assurance that the Adviser will be
successful in limiting the Fund's exposure to the risks associated with lower
rated securities. Because the Fund invests in securities in the lower rated
categories, the achievement of the Fund's goals is more dependent on the
Adviser's ability than would be the case if the Fund was investing in securities
in the higher rated categories.

                                       5
<PAGE>


Ratings.  Ratings for Bonds issued by various  jurisdictions  are noted  herein.
Such ratings  reflect only the respective  views of such  organizations,  and an
explanation of the  significance of such ratings may be obtained from the rating
agency  furnishing  the same.  There is no assurance that a rating will continue
for any given  period of time or that a rating will not be revised or  withdrawn
entirely by any or all of such rating  agencies,  if, in its or their  judgment,
circumstances so warrant.  Any downward revision or withdrawal of a rating could
have an  adverse  effect on the  market  prices  of any of the  bonds  described
herein.

Restricted Securities.  The Fund may purchase securities that are not registered
("restricted  securities")  under  the  Securities  Act of  1933  ("1933  Act"),
including  commercial  paper  issued in reliance on Section 4(2) of the 1933 Act
and securities offered and sold to "qualified  institutional  buyers" under Rule
144A  under the 1933  Act.  The Fund  will not  invest  more than 15% of its net
assets  in  illiquid  investments.  If  the  Trustees  determine,  based  upon a
continuing review of the trading markets for specific Section 4(2) paper or Rule
144A securities, that they are liquid, they will not be subject to the 15% limit
on illiquid  securities.  The Trustees have adopted  guidelines and delegated to
the Adviser the daily  function of  determining  the monitoring and liquidity of
restricted securities.  The Trustees,  however, will retain sufficient oversight
and  be  ultimately  responsible  for  the  determinations.  The  Trustees  will
carefully monitor the Fund's  investments in these securities,  focusing on such
important  factors,  among others,  as valuation,  liquidity and availability of
information.  This  investment  practice could have the effect of increasing the
level of illiquidity in the Fund if qualified  institutional buyers become for a
time uninterested in purchasing these restricted securities.

Participation Interests.  Participation interests may take the form of interests
in or of a lending syndicate.  The Fund's investments in participation interests
may be subject to its 15% net  assets  limitation  on  investments  in  illiquid
securities.  The fund may purchase only those participation interest that mature
in 60 days or less or, if  maturing  in more than 60 days,  that have a floating
rate that is automatically  adjusted at least once every 60 days.  Participation
interests in municipal  lease  obligations  will not be considered  illiquid for
purposes  of the Fund's 15%  limitation  on  illiquid  securities  provided  the
Adviser determines that there is a readily available market for such securities.

In reaching liquidity decisions, the Adviser will consider, among others, the
following factors: (1) the frequency of trades and quotes for the security; (2)
the number of dealers wishing to purchase or sell the security and the number of
other potential purchasers; (3) dealer undertakings to make a market in the
security and (4) the nature of the security and the nature of the marketplace
trades (e.g., the time needed to dispose of the security, the method of
soliciting offers and the mechanics of the transfer.) With respect to municipal
lease obligations, the Adviser also considers: (1) the willingness of the
municipality to continue, annually or biannually, to appropriate funds for
payment of the lease; (2) the general credit quality of the municipality and the
essentiality to the municipality of the property covered by the lease; (3) an
analysis of factors similar to that performed by nationally recognized
statistical rating organizations in evaluating the credit quality of a municipal
lease obligation, including (i) whether the lease can be canceled; (ii) if
applicable, what assurance there is that the assets represented by the lease can
be sold; (iii) the strength of the lessee's general credit (e.g., its debt,
administrative, economic and financial characteristics); (iv) the likelihood
that the municipality will discontinue appropriating funding for the leased
property because the property is no longer deemed essential to the operations of
the municipality (e.g., the potential for an event of nonappropriation); and (v)
the legal recourse in the event of failure to appropriate; and (4) any other
factors unique to municipal lease obligations as determined by the Adviser.

                                       6
<PAGE>


Repurchase  Agreements.  The Fund may enter into  repurchase  agreements for the
purpose of realizing  additional (taxable) income. In a repurchase agreement the
Fund buys a security  for a  relatively  short  period  (usually not more than 7
days)  subject to the  obligation  to sell it back to the issuer at a fixed time
and price plus accrued interest.  The Fund will enter into repurchase agreements
only with member banks of the Federal Reserve System and with "primary  dealers"
in U.S.  Government  securities.  The  Adviser  will  continuously  monitor  the
creditworthiness  of the  parties  with  whom the Fund  enters  into  repurchase
agreements.

The Fund has  established a procedure  providing that the securities  serving as
collateral  for  each  repurchase  agreement  must be  delivered  to the  Fund's
custodian  either  physically or in book-entry form and that the collateral must
be marked to market  daily to ensure  that each  repurchase  agreement  is fully
collateralized  at all times.  In the event of  bankruptcy or other default by a
seller  of  a  repurchase  agreement,   the  Fund  could  experience  delays  in
liquidating the underlying  securities during the period in which the Fund seeks
to enforce its rights thereto, possible subnormal levels of income, a decline in
value of the  underlying  securities  or lack of access to  income  during  this
period and the expense of enforcing its rights.

Reverse Repurchase  Agreements.  The Fund may also enter into reverse repurchase
agreements  which  involve the sale of U.S.  Government  securities  held in its
portfolio to a bank with an agreement that the Fund will buy back the securities
at a fixed  future  date at a fixed  price plus an agreed  amount of  "interest"
which may be reflected in the repurchase price.  Reverse  repurchase  agreements
are  considered  to be  borrowings by the Fund.  Reverse  repurchase  agreements
involve the risk that the market value of securities  purchased by the Fund with
proceeds  of the  transaction  may  decline  below the  repurchase  price of the
securities  sold by the Fund which it is obligated to repurchase.  The Fund will
also  continue to be subject to the risk of a decline in the market value of the
securities sold under the agreements  because it will reacquire those securities
upon effecting their repurchase. The Fund will not enter into reverse repurchase
agreements and other borrowings exceeding in the aggregate 33 1/3% of the market
value of its total assets.  To minimize  various risks  associates  with reverse
repurchase agreements,  the Fund will establish a separate account consisting of
highly  liquid,  marketable  securities  in an  amount  at  least  equal  to the
repurchase prices of these securities (plus accrued interest thereon) under such
agreements.  In addition, the Fund will not purchase additional securities while
all borrowings  are  outstanding.  The Funds will enter into reverse  repurchase
agreements  only with federally  insured banks or savings and loan  associations
which are  approved  in advance as being  creditworthy  by the  Trustees.  Under
procedures   established   by  the  Trustees,   the  Adviser  will  monitor  the
creditworthiness of the banks involved.

Options on Securities  and Securities  Indices.  The Fund may purchase and write
(sell)  call and put  options  on any  securities  in which it may invest on any
securities  index based on securities in which it may invest.  These options may
be  listed  on  national  domestic   securities   exchanges  or  traded  in  the
over-the-counter  market.  The Fund may write  covered put and call  options and
purchase put and call options to enhance total return,  as a substitute  for the
purchase or sale of securities,  or to protect against  declines in the value of
portfolio  securities  and against  increases  in the cost of  securities  to be
acquired.

Writing Covered Options. A call option on securities written by the Fund
obligates the Fund to sell specified securities to the holder of the option at a
specified price if the option is exercised at any time before the expiration
date. A put option on securities written by the Fund obligates the Fund to
purchase specified securities from the option holder at a specified price if the
option is exercised at any time before the expiration date. Options on
securities indices are similar to options on securities, except that the

                                       7
<PAGE>


exercise of securities index options requires cash settlement payments and does
not involve the actual purchase or sale of securities. In addition, securities
index options are designed to reflect price fluctuations in a group of
securities or segment of the securities market rather than price fluctuations in
a single security. Writing covered call options may deprive the Fund of the
opportunity to profit from an increase in the market price of the securities in
its portfolio. Writing covered put options may deprive the Fund of the
opportunity to profit from a decrease in the market price of the securities to
be acquired for its portfolio.

All call and put options written by the Fund are covered.  A written call option
or put option may be covered by (i) maintaining  cash or liquid  securities in a
segregated  account with a value at least equal to the Fund's  obligation  under
the option,  (ii) entering into an offsetting  forward  commitment  and/or (iii)
purchasing  an  offsetting  option or any other option  which,  by virtue of its
exercise  price or  otherwise,  reduces  the Fund's net  exposure on its written
option  position.  A written call option on securities  is typically  covered by
maintaining  the  securities  that are  subject  to the  option in a  segregated
account.  The Fund may  cover  call  options  on a  securities  index by  owning
securities  whose  price  changes  are  expected  to be  similar to those of the
underlying index.

The Fund may  terminate  its  obligations  under an exchange  traded call or put
option by purchasing an option identical to the one it has written.  Obligations
under  over-the-counter  options  may be  terminated  only by  entering  into an
offsetting  transaction with the counterparty to such option. Such purchases are
referred to as "closing purchase transactions."

Purchasing Options. The Fund would normally purchase call options in
anticipation of an increase, or put options in anticipation of a decrease
("protective puts") in the market value of securities of the type in which it
may invest. The Fund may also sell call and put options to close out its
purchased options.

The purchase of a call option would  entitle the Fund, in return for the premium
paid, to purchase  specified  securities at a specified  price during the option
period.  The Fund  would  ordinarily  realize a gain on the  purchase  of a call
option if, during the option  period,  the value of such  securities or currency
exceeded the sum of the exercise price, the premium paid and transaction  costs;
otherwise the Fund would realize either no gain or a loss on the purchase of the
call option.

The purchase of a put option would entitle the Fund, in exchange for the premium
paid,  to sell  specified  securities  at a  specified  price  during the option
period. The purchase of protective puts is designed to offset or hedge against a
decline in the market value of the Fund's portfolio securities.  Put options may
also be purchased by the Fund for the purpose of affirmatively benefiting from a
decline  in the  price of  securities  which it does  not  own.  The Fund  would
ordinarily  realize  a gain if,  during  the  option  period,  the  value of the
underlying  securities  decreased below the exercise price sufficiently to cover
the premium and  transaction  costs;  otherwise the Fund would realize either no
gain or a loss on the  purchase  of the put  option.  Gains  and  losses  on the
purchase of put options may be offset by countervailing  changes in the value of
the Fund's portfolio securities.  Under certain circumstances,  the Fund may not
be treated as the tax owner of a security if the Fund has purchased a put option
on the same security.  If this  occurred,  the interest on the security would be
taxable.

The Fund's options transactions will be subject to limitations established by
each of the exchanges, boards of trade or other trading facilities on which such
options are traded. These limitations govern the maximum number of options in
each class which may be written or purchased by a single investor or group of
investors acting in concert, regardless of whether the options are written or
purchased on the same or different exchanges, boards of trade or other trading
facilities or are held or written in one or more accounts or through one or more
brokers. Thus, the number of options which the Fund may write or purchase may be
affected by options written or purchased by other investment advisory clients of
the Adviser. An exchange, board of trade or other trading facility may order the
liquidation of positions found to be in excess of these limits, and it may
impose certain other sanctions.

Risks Associated with Options Transactions.  There is no assurance that a liquid
secondary   market  on  an  options  exchange  will  exist  for  any  particular
exchange-traded  option  or at any  particular  time.  If the Fund is  unable to
effect a closing  purchase  transaction  with respect to covered  options it has
written, the Fund will not be able to sell the underlying  securities or dispose
of  assets  held  in a  segregated  account  until  the  options  expire  or are
exercised. Similarly, if the Fund is unable to effect a closing sale transaction
with respect to options it has purchased,  it would have to exercise the options
in order to  realize  any  profit  and will  incur  transaction  costs  upon the
purchase or sale of underlying securities.

Reasons for the absence of a liquid  secondary market on an exchange include the
following:  (i) there may be insufficient  trading  interest in certain options;
(ii)  restrictions  may be imposed by an  exchange  on opening  transactions  or
closing  transactions  or  both;  (iii)  trading  halts,  suspensions  or  other
restrictions  may be imposed  with  respect to  particular  classes or series of
options;   (iv)  unusual  or  unforeseen   circumstances  may  interrupt  normal
operations  on an  exchange;  (v) the  facilities  of an exchange or the Options
Clearing  Corporation may not at all times be adequate to handle current trading
volume;  or (vi) one or more  exchanges  could,  for economic or other  reasons,
decide or be compelled at some future date to discontinue the trading of options
(or a particular class or series of options). If trading were discontinued,  the
secondary  market on that exchange (or in that class or series of options) would
cease to exist.  However,  outstanding  options on that  exchange  that had been
issued  by the  Options  Clearing  Corporation  as a result  of  trades  on that
exchange would continue to be exercisable in accordance with their terms.

The Fund's  ability to terminate  over-the-counter  options is more limited than
with  exchange-traded  options  and may  involve  the risk  that  broker-dealers
participating  in such  transactions  will not fulfill  their  obligations.  The
Adviser  will  determine  the  liquidity  of  each  over-the-counter  option  in
accordance with guidelines adopted by the Trustees.

The  writing  and  purchase of options is a highly  specialized  activity  which
involves  investment  techniques and risks different from those  associated with
ordinary  portfolio  securities  transactions.  The  successful  use of  options
depends in part on the Adviser's  ability to predict  future price  fluctuations
and, for hedging transactions, the degree of correlation between the options and
securities markets.

Futures  Contracts and Options on Futures  Contracts.  To seek to increase total
return or hedge against  changes in interest  rates and securities  prices,  the
Fund may purchase and sell various kinds of futures contracts,  and purchase and
write call and put options on these futures  contracts.  The Fund may also enter
into  closing  purchase  and  sale  transactions  with  respect  to any of these
contracts and options. The futures contracts may be based on various securities,
securities indices, and any other financial instruments and indices. All futures
contracts  entered  into by the Fund are traded on U.S.  exchanges  or boards of
trade that are licensed,  regulated or approved by the Commodity Futures Trading
Commission ("CFTC").

Futures Contracts. A futures contract may generally be described as an agreement
between  two parties to buy and sell  particular  financial  instruments  for an
agreed price during a designated  month (or to deliver the final cash settlement
price,  in the case of a contract  relating to an index or otherwise not calling
for physical delivery at the end of trading in the contract).

Positions taken in the futures markets are not normally held to maturity but are
instead liquidated through offsetting transactions which may result in a profit
or a loss. While futures contracts on securities will usually be liquidated in
this manner, the Fund may instead make, or take, delivery of the underlying
securities whenever it appears economically advantageous to do so. A clearing
corporation associated with the exchange on which futures contracts are traded
guarantees that, if still open, the sale or purchase will be performed on the
settlement date.

Hedging and Other  Strategies  With Future  Contracts.  Hedging is an attempt to
establish  with more  certainty  than would  otherwise be possible the effective
price or rate of return on  portfolio  securities  or  securities  that the Fund
proposes to acquire.  When securities  prices are falling,  the Fund can seek to
offset a decline in the value of its current  portfolio  securities  through the
sale of futures contracts.  When securities prices are rising, the Fund, through
the purchase of futures contracts,  can attempt to secure better rates or prices
than  might  later  be  available  in the  market  when it  effects  anticipated
purchases.

The Fund may,  for  example,  take a "short"  position in the futures  market by
selling futures contracts in an attempt to hedge against an anticipated  decline
in market prices that would adversely  affect the value of the Fund's  portfolio
securities. Such futures contracts may include contracts for the future delivery
of securities  held by the Fund or securities  with  characteristics  similar to
those of the Fund's portfolio securities.

If, in the opinion of the Adviser,  there is a sufficient  degree of correlation
between price trends for the Fund's portfolio  securities and futures  contracts
based on other financial  instruments,  securities indices or other indices, the
Fund may also enter into such futures contracts as part of its hedging strategy.
Although under some  circumstances  prices of securities in the Fund's portfolio
may be more or less volatile than prices of such futures contracts,  the Adviser
will  attempt to  estimate  the extent of this  volatility  difference  based on
historical patterns and compensate for any differential by having the Fund enter
into a greater or lesser number of futures contracts or by attempting to achieve
only a partial  hedge  against  price  changes  affecting  the Fund's  portfolio
securities.

When a short hedging  position is successful,  any  depreciation in the value of
portfolio  securities will be substantially  offset by appreciation in the value
of the futures position.  On the other hand, any  unanticipated  appreciation in
the value of the Fund's portfolio  securities would be substantially offset by a
decline in the value of the futures position.

On other  occasions,  the Fund may take a "long" position by purchasing  futures
contracts.  This  would be done,  for  example,  when the Fund  anticipates  the
subsequent purchase of particular securities when it has the necessary cash, but
expects the prices then available in the applicable  market to be less favorable
than prices that are currently  available.  The Fund may also  purchase  futures
contracts as a substitute for transactions in securities to alter the investment
characteristics of portfolio securities or to gain or increase its exposure to a
particular securities market.

Options on Futures Contracts. The Fund may purchase and write options on futures
for the same purposes as its transactions in futures contracts.  The purchase of
put and call options on futures  contracts will give the Fund the right (but not
the obligation) for a specified price to sell or to purchase,  respectively, the
underlying  futures  contract  at any time  during  the  option  period.  As the
purchaser  of an option on a futures  contract,  the Fund obtains the benefit of
the futures position if prices move in a favorable direction but limits its risk
of loss in the event of an unfavorable price movement to the loss of the premium
and transaction costs.

The writing of a call option on a futures contract generates a premium which may
partially offset a decline in the value of the Fund's assets. By writing a call
option, the Fund becomes obligated, in exchange for the premium (upon exercise
of the option) to sell a futures contract if the option is exercised, which may
have a value higher than the exercise price. Conversely, the writing of a put
option on a futures contract generates a premium which may partially offset an
increase in the price of securities that the Fund intends to purchase. However,
the Fund becomes obligated (upon exercise of the option) to purchase a futures
contract if the option is exercised, which may have a value lower than the
exercise price. The loss incurred by the Fund in writing options on futures is
potentially unlimited and may exceed the amount of the premium received.

                                       10
<PAGE>


The  holder or writer of an option  on a  futures  contract  may  terminate  its
position by selling or purchasing an offsetting option of the same series. There
is no guarantee  that such  closing  transactions  can be  effected.  The Fund's
ability to establish  and close out positions on such options will be subject to
the development and maintenance of a liquid market.

Other  Considerations.  The Fund will  engage in  futures  and  related  options
transactions  either for bona fide hedging purposes or to seek to increase total
return as  permitted by the CFTC.  To the extent that the Fund is using  futures
and related  options for hedging  purposes,  futures  contracts  will be sold to
protect  against a  decline  in the  price of  securities  that the Fund owns or
futures  contracts  will be purchased to protect the Fund against an increase in
the price of securities it intends to purchase. The Fund will determine that the
price  fluctuations  in the futures  contracts  and options on futures  used for
hedging purposes are substantially  related to price  fluctuations in securities
held by the Fund or securities or instruments  which it expects to purchase.  As
evidence  of its hedging  intent,  the Fund  expects  that on 75% or more of the
occasions on which it takes a long  futures or option  position  (involving  the
purchase of futures contracts),  the Fund will have purchased, or will be in the
process of  purchasing,  equivalent  amounts of related  securities  in the cash
market at the time when the futures or option  position is closed out.  However,
in particular cases, when it is economically advantageous for the Fund to do so,
a long futures  position may be terminated  or an option may expire  without the
corresponding purchase of securities or other assets.

To the  extent  that the Fund  engages  in  nonhedging  transactions  in futures
contracts  and options on futures,  the  aggregate  initial  margin and premiums
required to establish these  nonhedging  positions will not exceed 5% of the net
asset  value of the Fund's  portfolio,  after  taking  into  account  unrealized
profits and losses on any such  positions and excluding the amount by which such
options were in-the-money at the time of purchase.

Transactions  in futures  contracts  and  options on futures  involve  brokerage
costs,  require  margin  deposits  and,  in the case of  contracts  and  options
obligating  the Fund to purchase  securities,  require  the Fund to  establish a
segregated account consisting of cash or liquid securities in an amount equal to
the underlying value of such contracts and options.

While  transactions  in futures  contracts  and  options  on futures  may reduce
certain risks,  these  transactions  themselves  entail certain other risks. For
example, unanticipated changes in interest rates or securities prices may result
in a poorer overall performance for the Fund than if it had not entered into any
futures contracts or options transactions.

Perfect correlation between the Fund's futures positions and portfolio positions
will be impossible to achieve. In the event of an imperfect  correlation between
a futures  position and a portfolio  position which is intended to be protected,
the desired  protection  may not be obtained and the Fund may be exposed to risk
of loss.

Some futures contracts or options on futures may become illiquid under adverse
market conditions. In addition, during periods of market volatility, a commodity
exchange may suspend or limit trading in a futures contract or related option,
which may make the instrument temporarily illiquid and difficult to price.
Commodity exchanges may also establish daily limits on the amount that the price
of a futures contract or related option can vary from the previous day's
settlement price. Once the daily limit is reached, no trades may be made that
day at a price beyond the limit. This may prevent the Fund from closing out
positions and limiting its losses.

Structured  or Hybrid  Notes.  The Fund may invest in  "structured"  or "hybrid"
notes.  The  distinguishing  feature of a structured  or hybrid note is that the
amount  of  interest  and/or  principal  payable  on the  note is  based  on the
performance of a benchmark asset or market other than fixed income securities or
interest  rates.  Examples of these  benchmarks  include stock prices,  currency
exchange rates and physical  commodity  prices.  Investing in a structured  note
allows  the Fund to gain  exposure  to the  benchmark  market  while  fixing the
maximum  loss that the Fund may  experience  in the event that  market  does not
perform as expected. Depending on the terms of the note, the Fund may forego all
or part of the  interest  and  principal  that would be payable on a  comparable
conventional  note; the Fund's loss cannot exceed this foregone  interest and/or
principal. An investment in structured or hybrid notes involves risks similar to
those associated with a direct investment in the benchmark asset.

Indexed  Securities.  The Fund  may  invest  in  indexed  securities,  including
floating rate  securities  that are subject to a maximum  interest rate ("capped
floaters") and leveraged inverse floating rate securities  ("inverse  floaters")
(up to 10% of the Fund's total assets). The interest rate or, in some cases, the
principal  payable at the maturity of an indexed security may change  positively
or inversely in a relation to one or more interest rates,  financial indices, or
other financial  indicators  ("reference  prices").  An indexed  security may be
leveraged to the extent that the magnitude of any change in the interest rate or
principal  payable on an  indexed  security  is a multiple  of the change in the
reference price.  Thus,  indexed  securities may decline in value due to adverse
market charges in interest rates or other reference prices.

Risk  Associated With Specific Types of Derivative  Debt  Securities.  Different
types of derivative  debt  securities are subject to different  combinations  of
prepayment,  extension and/or interest rate risk. The risk of early  prepayments
is the primary risk associated with interest only debt securities ("IOs"), super
floaters and other leveraged floating rate instruments. In some instances, early
prepayments  may result in a  complete  loss of  investment  in certain of these
securities.  The primary risks  associated  with certain other  derivative  debt
securities are the potential  extension of average life and/or  depreciation due
to rising interest rates.

Derivative debt securities include floating rate securities based on the Cost of
Funds Index ("COFI  floaters"),  other "lagging rate" floating rate  securities,
floating rate  securities  that are subject to a maximum  interest rate ("capped
floaters"),  leveraged  inverse floating rate securities  ("inverse  floaters"),
principal only debt securities  ("POs") and certain residual or support branches
of index amortizing notes.  Index amortizing notes are subject to extension risk
resulting from the issuer's failure to exercise its option to call or redeem the
notes  before  their  stated  maturity  date.  Leveraged  inverse IOs present an
especially intense combination of prepayment, extension and interest rate risks.

Other types of floating rate  derivative  debt  securities  present more complex
types of interest  rate risks.  For example,  range  floaters are subject to the
risk that the  coupon  will be  reduced to below  market  rates if a  designated
interest rate floats outside of a specified  interest rate band or collar.  Dual
index or yield curve  floaters  are subject to  depreciation  in the event of an
unfavorable change in the spread between two designated interest rates. X- reset
floaters  have a coupon that  remains  fixed for more than one  accrual  period.
Thus, the type of risk involved in these securities depends on the terms of each
individual X-reset floater.

Forward Commitment and When-Issued Securities. The Fund may purchase securities
on a when-issued or forward commitment basis. "When-issued" refers to securities
whose terms are available and for which a market exists, but which have not been
issued. The Fund will engage in when-issued transactions with respect to
securities purchased for its portfolio in order to obtain what is considered to

                                       12
<PAGE>


be an advantageous price and yield at the time of the transaction. For
when-issued transactions, no payment is made until delivery is due, often a
month or more after the purchase. In a forward commitment transaction, the Fund
contracts to purchase securities for a fixed price at a future date beyond
customary settlement time.

When the Fund engages in forward  commitment and  when-issued  transactions,  it
relies on the seller to consummate the transaction. The failure of the issuer or
seller to  consummate  the  transaction  may  result in the  Fund's  losing  the
opportunity  to obtain a price  and yield  considered  to be  advantageous.  The
purchase  of  securities  on a  when-issued  or  forward  commitment  basis also
involves a risk of loss if the value of the  security to be  purchased  declines
prior to the settlement date.

On the date the Fund  enters  into an  agreement  to  purchase  securities  on a
when-issued or forward  commitment  basis, the Fund will segregate in a separate
account cash or liquid securities equal in value to the Fund's commitment. These
assets will be valued daily at market, and additional cash or securities will be
segregated  in a  separate  account to the  extent  that the total  value of the
assets in the account declines below the amount of the when-issued  commitments.
Alternatively, the Fund may enter into offsetting contracts for the forward sale
of other securities that it owns.

Swaps,  Caps,  Floors  and  Collars.  As one way of  managing  its  exposure  to
different types of investments, the Fund may enter into interest rate swaps, and
other types of swap  agreements such as caps,  collars and floors.  In a typical
interest  rate  swap,  one party  agrees  to make  regular  payments  equal to a
floating  interest  rate  times a  "notional  principal  amount,"  in return for
payments equal to a fixed rate times the same amount,  for a specified period of
time.  Swaps may also depend on other  prices or rates,  such as the value of an
index or mortgage prepayment rates.

In a typical cap or floor  agreement,  one party  agrees to make  payments  only
under  specified  circumstances,  usually in return for  payment of a fee by the
other party. For example, the buyer of an interest rate cap obtains the right to
receive  payments  to the  extent  that a  specified  interest  rate  exceeds an
agreed-upon  level,  while the seller of an interest  rate floor is obligated to
make payments to the extent that a specified interest rate falls below an agreed
upon  level.  An  interest  rate  collar  combines  elements of buying a cap and
selling a floor.

Swap agreements will tend to shift the Fund's investment  exposure from one type
of  investment to another.  Caps and floors have an effect  similar to buying or
writing options. Depending on how they are used, swap agreements may increase or
decrease the overall  volatility of the Fund's  investments  and its share price
and yield.

Swap agreements are sophisticated  hedging  instruments that typically involve a
small  investment  of cash  relative to the  magnitude  of risks  assumed.  As a
result,  swaps can be highly volatile and may have a considerable  impact on the
Fund's  performance.  Swap  agreements  are  subject  to  risks  related  to the
counterpart's  ability to perform, and may decline in value if the counterpart's
credit worthiness deteriorates.  The Fund may also suffer losses if it is unable
to  terminate  outstanding  swap  agreements  or  reduce  its  exposure  through
offsetting transactions. The Fund will maintain in a segregated account with its
custodian,  cash or liquid,  high grade debt securities equal to the net amount,
if any,  of the  excess of the  Fund's  obligations  over its  entitlement  with
respect to swap, cap, collar or floor transactions.

Lending of Securities. For purposes of realizing additional (taxable) income,
the Fund may lend portfolio securities to brokers, dealers, and financial
institutions if the loan is collateralized by cash or U.S. Government securities
according to applicable regulatory requirements. The Fund may reinvest any cash
collateral in short-term securities and money market funds. When the Fund lends
portfolio securities, there is a risk that the borrower may fail to return the
securities involved in the transaction. As a result, the Fund may incur a loss
or, in the event of the borrower's bankruptcy, the Fund may be delayed in or
prevented from liquidating the collateral. It is a fundamental policy of the
Fund not to lend portfolio securities having a total value exceeding 33 1/3% of
its total assets.

                                       13
<PAGE>


Short-Term  Trading  and  Portfolio  Turnover.  The Fund may attempt to maximize
current income through short-term  portfolio trading.  This will involve selling
portfolio  instruments and purchasing different instruments to take advantage of
yield   disparities   in  different   segments  of  the  market  for  government
obligations.  Short- term  trading may have the effect of  increasing  portfolio
turnover  rate.  The  portfolio  turnover  rate  for the Fund is  calculated  by
dividing  the  lower of that  Fund's  annual  sales or  purchases  of  portfolio
securities  (exclusive of purchases or sales of all securities  whose maturities
at the time of acquisition  were 1 year or less) by the monthly average value of
the  securities  in the Fund during the year. A high rate of portfolio  turnover
(100% or greater) involves correspondingly higher brokerage expenses. The Fund's
portfolio  turnover rate is set forth in the table under the caption  "Financial
Highlights" in the Prospectus.

Special Risks

The following  information as to certain special risks associated with investing
in  Massachusetts  constitutes only a brief summary and does not purport to be a
complete description of the considerations associated with such investments. The
information is based in part on information from official  statements related to
securities offerings of Massachusetts issuers and is believed to be accurate.

MASSACHUSETTS TAX-EXEMPT BONDS

The economy of the Commonwealth of Massachusetts (the "Commonwealth")  continues
to remain strong with  unemployment  falling to 3.1% for August 1999, the lowest
annual rate since 1988. The Massachusetts  annual average  unemployment rate has
now been on the decline for eight  consecutive  years,  since peaking at 9.1% in
1991, and has been below the US rate for the past six years.

The  financial  condition of the  Commonwealth  has improved  over the last five
years.   This  improvement   reflects  the  combination  of  implementing   more
conservative  fiscal policy and budgetary  practices,  as well as increasing tax
revenues  from  a  steadily  growing  state  economy.  Since  Fiscal  1994,  the
Commonwealth's  tax revenues have  increased  from $10.6 billion to an estimated
$14.5 billion in Fiscal 2000, an average annual gain of 6%. For Fiscal 2000, tax
revenues are expected to increase 3.3% over 1999  estimates,  while  including a
proposed  reduction in the tax rate on certain personal income of $226 million .
Initial projections suggest that Fiscal 2000 could mark the commonwealth's ninth
consecutive operating surplus.

In response to continued strong economic growth,  sound financial position,  and
the  significant   progress  made  in  reducing  the  state's  unfunded  pension
liability,  Moody's  raised the  Commonwealth's  credit rating from A1 to Aa3 in
April of 1998. S&P currently rates it AA- and Fitch Investors also accords a AA-
rating to the Commonwealth.

Prior Fiscal Years

Fiscal 1996. The Fiscal 1996 budget totaled approximately $16.9 billion, a $684
million, or 4.5% increase over Fiscal 1995 spending. Comprehensive educational
reform funding with a $233 million addition represented the largest individual
expenditure increase. The Commonwealth ended Fiscal Year 1996 showing a gain of
5.5% in total revenues and an operating surplus of 2.8%. An unexpected increase

                                       14
<PAGE>


in income tax revenues produced sufficient revenues to fully fund the
Stabilization Reserve to $543 million, a threshold set equal to 5% of tax
revenues less debt service, and to establish a tax reduction reserve equal to
$234 million. Monies in the tax reduction reserve were applied as one-time tax
credit for Fiscal Year 1997.

Fiscal 1997. The 1997 budget  provided for  expenditures  of $17.7  billion,  an
increase of 4.8% over Fiscal 1996. This budget  incorporated an expected decline
in income tax  revenues  and  anticipated  using  reserves  to  maintain  budget
balance.  Tax revenues,  however,  increased by 6.7% from 1996. On August 29th a
supplemental  appropriation bill was enacted, which provided for $195 million in
additional  fiscal 1997  appropriations,  of which $63.7  million  were  carried
forward into fiscal 1998.

The Legislature  established a Capital  Investment Trust Fund to provide for the
transfer  of $229.8  million to finance  specified  expenditures  for  equipment
purchases,  deferred maintenance and repairs,  technology upgrades,  and capital
purchases and improvements.  The spending authorization expires in 1999 when any
unexpended  balances in the fund will be transferred to the Stabilization  Fund.
In addition to the mandated transfer,  the legislature  transferred $100 million
to the Stabilization  Fund, and $128 million to a Caseload  Increase  Mitigation
Fund which had been established in fiscal budget 1998.

Fiscal  1998.  Governor  Weld  approved  the fiscal  1998 budget  providing  for
appropriations  of  approximately  $18.4  billion on July 10,  1997.  The budget
represented a 2.8% increase over fiscal 1997 expenditures and was based on a tax
revenue forecast of $12.85 billion and a budget revenue forecast of $18.749.  On
July 29,  1997 Paul  Cellucci  became  Acting  Governor  of  Massachusetts  when
Governor  Weld  resigned to pursue the U.S.  Ambassadorship  to Mexico.  The tax
forecast was revised  after review of quarterly  receipts and increased to $13.3
billion on January 16, 1998.  Preliminary  revenues for fiscal 1998 are a record
$14.026 billion, up $1.161 billion or 9% from fiscal 1997.

Supplemental  appropriations  were  approved  in  the  amount  of  $94  million,
including the transfer of approximately $34.8 million to the Massachusetts Water
Pollution Abatement Trust for the state revolving fund programs. On November 26,
1997 Acting  Governor  Cellucci  approved  legislation  transferring  off-budget
$206.3 million  Department of Medical  assistance  reserves to indemnify certain
medical facilities  against losses that may result from providing  uncompensated
care.

Standard & Poor's upgraded  Massachusetts to AA- from A+ in October 1997, citing
strong  debt  management  and  favorable  reserves.  In January  1998 Fitch also
upgraded the  Commonwealth to AA- from A+ and Moody's followed suit and upgraded
its rating in the  spring of 1998,  from A1 to AA3.  All of the rating  agencies
cited   concerns   surrounding   the  funding  of  the  $11.6  billion   Central
Artery/Tunnel Project. Much of the funding is expected to come from federal aid,
however,  any shortfalls will place the burden on the general  obligation on the
state and upon the Turnpike Authority and Port Authority.

Fiscal  1999.  Estimated  spending in 1999 totaled $20  billion,  against  total
revenue of $21.9 billion. Revenues in 1999 consistently exceeded estimates, with
year-end total  exceeding even the May revision by some $300 million.  The state
has restored  its  combined  undesignated  balance and  stabilization  fund to a
healthy $1.7 billion or 8.2% of revenues, as of 6/30/99.

Fiscal 1999 budget recommendations call for appropriations of $945.3 million for
pension funding, $93.9 million less tan the amount appropriated for the prior
fiscal year. The recommended amount reflects the elimination in 1997 of the
Commonwealth's responsibility for funding cost-or-living adjustments and the
adoption of a revised funding schedule. The proposed budget also includes a $20
million reserve to reduce the unfunded pension liabilities attributable to
former employees of Franklin, Hampden, Middlesex and Worcester counties.

Current Fiscal Year

Fiscal 2000. The Massachusetts Legislature passed a budget more than four months
late, approving a $20.87 billion FY 2000 budget on 11/10/99.  The 2000 budget is
the latest passed since 1965. Governor Paul Cellucci then used his veto power to
reduce some $250  million  from the  budget,  but state  lawmakers  subsequently
overrode many of the  governor's  vetoes,  and returned some $190 million to the
budget.  In the end, FY 2000 budget passed.  The FY 2000 budget  increases state
spending  by some 7%, and phases in tax cuts  reducing  the income tax rate from
5.95% to 5.75%  over  three  years.  One major  component  of the  budget  was a
restructuring  of the  finances  of the  MBTA  from  what  is  essentially  full
reimbursement to a defined revenue source,  with any expenditure  overages to be
made up from other sources. The budget also provides additional funds for Senior
citizen drug costs and other elderly services.

Credit Factors

Massachusetts  has one of the  highest  debt loads  among the  states.  Debt per
capita is $2,580, compared to the state median of $422 and debt, as a percent of
personal  income is 7.8%,  compared to the median of 2.1%.  Financing of the $12
billion Central Artery Tunnel Project remains a concern.  Forty-five  percent of
the funding is to come from  federal aid with the  remainder  from  bondings and
contributions  from  the  Commonwealth,  the  Turnpike  Authority  and the  Port
Authority.  Ultimately,  the  Commonwealth  is responsible for any shortfalls in
federal funding or increased costs.

Despite these  concerns,  Massachusetts  has a vibrant and diverse  economy.  In
August 1999,  unemployment  dipped to 3.1%.  Employment has risen by 400,000 new
jobs since 1991. The  Commonwealth  has  demonstrated  sound fiscal  management;
produced strong operating  results and has been successful in strengthening  its
cash and reserve balances.

The  investment  objectives  and  policies  described  above  under the  caption
"Investment  Objective and Policies" are not  fundamental  and may be changed by
the Trustees without shareholder approval. The policy of the Fund requiring that
under  normal  circumstances  at least 80% of the Fund's  net assets  consist of
Tax-Exempt  Bonds is fundamental and may not be changed by the Trustees  without
shareholder approval.

Investment Restrictions

Fundamental Investment Restrictions. The fundamental investment restrictions
will not be changed for the Fund without the approval of a majority of the
Fund's outstanding voting securities which, as used in the Prospectus and this
Statement of Additional Information, means the approval by the lesser of (1) the
holders of 67% or more of the Fund's shares represented at a meeting if more
than 50% of the Fund's outstanding shares are present in person or by proxy at
that meeting or (2) more than 50% of the Fund's outstanding shares.

The Fund may not:

         (1)      Issue senior securities, except as permitted by paragraphs (2)
                  and (7) below. For purposes of this restriction,  the issuance
                  of  shares of  beneficial  interest  in  multiple  classes  or
                  series, the purchase or sale of options, futures contracts and
                  options  on  futures  contracts,   forward  commitments,   and
                  repurchase  agreements  entered  into in  accordance  with the
                  Fund's  investment  policies,  and  the  pledge,  mortgage  or
                  hypothecation  of the  Fund's  assets  within  the  meaning of
                  paragraph (3) below are not deemed to be senior securities.

         (2)      Borrow  money,  except from banks as a  temporary  measure for
                  extraordinary  emergency  purposes in amounts not to exceed 33
                  1/3%  of  the  Fund's  total  assets   (including  the  amount
                  borrowed)  taken at market  value.  The Fund will not purchase
                  securities while borrowings are outstanding.

         (3)      Pledge,  mortgage or hypothecate its assets,  except to secure
                  indebtedness permitted by paragraph (2) above and then only if
                  such pledging, mortgaging or hypothecating does not exceed 10%
                  of the Fund's total assets taken at market value.

         (4)      Act as an underwriter, except to the extent that in connection
                  with  the  disposition  of Fund  securities,  the  Fund may be
                  deemed to be an underwriter for purposes of the Securities Act
                  of 1933.  The Fund may also  participate as part of a group in
                  bidding for the purchase of Tax- Exempt Bonds directly from an
                  issuer in order to take  advantage of the lower purchase price
                  available to members of such groups.

         (5)      Purchase or sell real estate or any interest therein, but this
                  restriction  shall  not  prevent  the Fund from  investing  in
                  Tax-Exempt Bonds secured by real estate or interests therein.

         (6)      Make  loans,  except  that the  Fund  (1) may  lend  portfolio
                  securities in accordance with the Fund's  investment  policies
                  in an amount up to 33 1/3% of the Fund's total assets taken at
                  market value,  (2) enter into repurchase  agreements,  and (3)
                  purchase all or a portion of an issue of debt securities, bank
                  loan  participation  interests,  bank certificates of deposit,
                  bankers' acceptances,  debentures or other securities, whether
                  or not the purchase is made upon the original  issuance of the
                  securities.

         (7)      Purchase or sell  commodities or commodity  contracts or puts,
                  calls or combinations  of both,  except options on securities,
                  securities indices,  currency and other financial instruments,
                  futures contracts on securities,  securities indices, currency
                  and other  financial  instruments  and options on such futures
                  contracts, forward commitments,  interest rate swaps, caps and
                  floors,  securities  index put or call warrants and repurchase
                  agreements   entered  into  in  accordance   with  the  Fund's
                  investment policies.

         (8)      Purchase the securities of issuers  conducting their principal
                  business  activity in the same industry if,  immediately after
                  such purchase,  the value of its  investments in such industry
                  would  exceed 25% of its total assets taken at market value at
                  the time of each investment. (Tax- Exempt Bonds and securities
                  issued or guaranteed by the United States  Government  and its
                  agencies  and   instrumentalities  are  not  subject  to  this
                  limitation.)

                                       17

         (9)      Purchase   securities  of  an  issuer  (other  than  the  U.S.
                  Government,  its  agencies  or  instrumentalities),   if  such
                  purchase  would cause more than 10 percent of the  outstanding
                  voting securities of such issuer to be held by the Fund.

Non-fundamental Investment Restrictions. The following investment restrictions
are designated as non-fundamental and may be changed by the Trustees without
shareholder approval:

The Fund may not:

         (1)      Except as permitted by fundamental  investment restriction (4)
                  above,  participate on a joint or  joint-and-several  basis in
                  any securities  trading account.  The "bunching" of orders for
                  the sale or purchase of marketable  Fund securities with other
                  accounts   under  the   management  of  the  Adviser  to  save
                  commissions  or to average  prices among them is not deemed to
                  result in a joint securities trading account.

         (2)      Purchase  securities  on margin or make short sales  unless by
                  virtue of its ownership of other securities,  the Fund has the
                  right to obtain  securities  equivalent  in kind and amount to
                  the  securities  sold short and, if the right is  conditional,
                  the sale is made  upon the same  conditions,  except  that the
                  Fund may obtain such  short-term  credits as may be  necessary
                  for the clearance of purchases and sales of securities.

         (3)      Purchase a security if, as a result,  (i) more than 10% of the
                  Fund's  total assets  would be invested in the  securities  of
                  other investment companies, (ii) the Fund would hold more than
                  3% of the  total  outstanding  voting  securities  of any  one
                  investment  company, or (iii) more than 5% of the Fund's total
                  assets  would  be  invested  in  the  securities  of  any  one
                  investment company.  These limitations do not apply to (a) the
                  investment  of  cash  collateral,  received  by  the  Fund  in
                  connection with lending the Fund's  portfolio  securities,  in
                  the  securities  of open-end  investment  companies or (b) the
                  purchase  of shares of any  investment  company in  connection
                  with a merger,  consolidation,  reorganization  or purchase of
                  substantially all of the assets of another investment company.
                  Subject to the above percentage limitations,  the Fund may, in
                  connection  with the  John  Hancock  Group  of Funds  Deferred
                  Compensation Plan for Independent Trustees/Directors, purchase
                  securities  of  other  investment  companies  within  the John
                  Hancock Group of Funds.

         (4)      invest more than 15% of its net assets in illiquid securities.

If a percentage  restriction on investment or utilization of assets as set forth
above  is  adhered  to at the time an  investment  is made,  a later  change  in
percentage  resulting from changes in the value of the Fund's assets will not be
considered a violation of the restriction.

THOSE RESPONSIBLE FOR MANAGEMENT

The  business  of the Fund is  managed  by the  Trustees  of the Trust who elect
officers who are responsible  for the day-to-day  operations of the Fund and who
execute  policies  formulated  by the Trustees.  Several of the officers  and/or
Trustees  of the Fund are also  officers  and/or  directors  of the  Adviser  or

was organized in 1968 and has more than $30 billion in assets under management
in its capacity as investment adviser to the Funds and other funds in the John

affiliate of the Life Company, one of the most recognized and respected
financial institutions in the nation. With total assets under management of more
than $100 billion, the Life Company is one of the ten largest life insurance
companies in the United States, and carries a high rating from Standard and

for over 130 years.

                                       26
<PAGE>


The Fund has entered  into an  investment  management  contract  (the  "Advisory
Agreement")  with the Adviser  which was  approved  by the Fund's  shareholders.
Pursuant to the Advisory Agreement,  the Adviser will: (a) furnish  continuously
an  investment  program  for the  Fund and  determine,  subject  to the  overall
supervision and review of the Trustees,  which investments  should be purchased,
held,  sold or exchanged,  and (b) provide  supervision  over all aspects of the
Fund's  operations  except those which are  delegated  to a custodian,  transfer
agent or other agent.

The Fund bears all costs of its  organization  and operation,  including but not
limited to  expenses  of  preparing,  printing  and  mailing  all  shareholders'
reports,  notices,  prospectuses,  proxy  statements  and reports to  regulatory
agencies;  expenses relating to the issuance,  registration and qualification of
shares;   government  fees;   interest   charges;   expenses  of  furnishing  to
shareholders  their account  statements;  taxes;  expenses of redeeming  shares;
brokerage  and  other  expenses   connected  with  the  execution  of  portfolio
securities  transactions;  expenses pursuant to the Fund's plan of distribution;
fees and expenses of custodians  including those for keeping books and accounts,
maintaining a committed  line of credit and  calculating  the net asset value of
shares;  fees and expenses of transfer  agents and dividend  disbursing  agents;
legal, accounting,  financial, management, tax and auditing fees and expenses of
the Fund (including an allocable portion of the cost of the Adviser's  employees
rendering such services to the subject Fund);  the  compensation and expenses of
Trustees who are not otherwise  affiliated with the Trust, the Adviser or any of
their  affiliates;  expenses of  Trustees'  and  shareholders'  meetings;  trade
association memberships; insurance premiums; and any extraordinary expenses.

As compensation for its services under the Advisory Agreement, the Fund pays the
Adviser  monthly a fee based on a stated  percentage  of the  average  daily net
assets of the Fund as follows:


               Net Asset Value                               Annual Rate
               ---------------                               -----------

             First $250 million                                 0.500%
              Next $250 million                                 0.450%
              Next $500 million                                 0.425%
              Next $250 million                                 0.400%
       Amounts over $1,250,000,000                              0.300%

From time to time, the Adviser may reduce its fee or make other  arrangements to
limit the Fund's  expenses to a specified  percentage  of its average  daily net
assets.  The  Adviser  retains the right to reimpose a fee and recover any other
payments to the extent that,  at the end of any fiscal year,  the Fund's  annual
expenses fall below this limit.

For the years ended August 31, 1997,  1998 and 1999,  the management fee paid by
the Fund to the Adviser amounted to $64,441, $71,563 and $129,739, for services,
respectively.

Securities held by the Fund may also be held by other funds or investment
advisory clients for which the Adviser or its affiliates provide investment
advice. Because of different investment objectives or other factors, a
particular security may be bought for one or more funds or clients when one or
more are selling the same security. If opportunities for purchase or sale of
securities by the Adviser or for other funds or clients for which the Adviser
renders investment advice arise for consideration at or about the same time,
transactions in such securities will be made, insofar as feasible, for the
respective funds or clients in a manner deemed equitable to all of them. To the
extent that transactions on behalf of more than one client of the Adviser or its
affiliates may increase the demand for securities being purchased or the supply
of securities being sold, there may be an adverse effect on price.

                                       27
<PAGE>


Pursuant to the Advisory  Agreement,  the Adviser is not liable for any error of
judgment or mistake of law or for any loss  suffered  by the Fund in  connection
with the matters to which their respective  Advisory Agreement relate,  except a
loss resulting from willful  misfeasance,  bad faith or gross  negligence on the
part of the Adviser in the performance of its duties or from reckless  disregard
of the obligations and duties under the Advisory Agreement.

Under the Advisory  Agreement,  the Fund may use the name "John  Hancock" or any
name derived from or similar to it only for so long as the Advisory Agreement or
any  extension,  renewal or  amendment  thereof  remains in effect.  If a Fund's
Advisory  Agreement  is no longer in  effect,  the Fund (to the  extent  that it
lawfully can) will cease to use such name or any other name  indicating  that it
is advised by or otherwise connected with the Adviser. In addition,  the Adviser
or the Life  Company  may grant the  non-exclusive  right to use the name  "John
Hancock" or any similar name to any other  corporation or entity,  including but
not  limited  to any  investment  company  of  which  the  Life  Company  or any
subsidiary  or  affiliate  thereof  or  any  successor  to the  business  of any
subsidiary or affiliate thereof shall be the investment adviser.

The continuation of the Advisory Agreement and Distribution Agreement (discussed
below) was  approved by all of the  Trustees.  The  Advisory  Agreement  and the
Distribution  Agreement will continue in effect from year to year, provided that
its  continuance  is approved  annually both (i) by the holders of a majority of
the outstanding voting securities of the Trust or by the Trustees, and (ii) by a
majority of the Trustees who are not parties to the  Agreement,  or  "interested
persons" of any such  parties.  Both  Agreements  may be  terminated  on 60 days
written notice by any party or by a vote of a majority of the outstanding voting
securities of the Fund and will terminate automatically if assigned.

Accounting and Legal Services  Agreement The Trust,  on behalf of the Fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this Agreement,  the Adviser  provides the Fund with certain tax,  accounting
and legal  services.  For the fiscal years ended August 31, 1997, 1998 and 1999,
the Fund paid the  Adviser  $10,451,  $10,447  and  $10,866,  respectively,  for
services under this Agreement.


Personnel of the Adviser and its affiliates may trade securities for their
personal accounts. The Fund also may hold, or may be buying or selling, the same
securities. To prevent the Fund from being disadvantaged, the Adviser and its
affiliates and the Fund have adopted a code of ethics which restricts the
trading activity of those personnel.


Distribution ContractS

The Fund has a Distribution Agreement with John Hancock Funds. Under the
agreement, John Hancock Funds is obligated to use its best efforts to sell
shares of each class on behalf of the Fund. Shares of the Fund are also sold by
selected broker-dealers (the "Selling Brokers") which have entered into selling
agency agreements with John Hancock Funds. These Selling Brokers are authorized
to designate other intermediaries to receive purchase and redemption orders on
behalf of the Fund. John Hancock Funds accepts orders for the purchase of the
shares of the Fund that are continually offered at net asset value next
determined, plus an applicable sales charge, if any. In connection with the sale
of Fund shares, John Hancock Funds and Selling Brokers receive compensation from
a sales charge imposed, in the case of Class A shares, at the time of sale. In
the case of Class B or Class C shares, the broker receives compensation
immediately but John Hancock Funds is compensated on a deferred basis.

                                       28
<PAGE>



Total underwriting commissions for sales of the Fund's Class A shares for the
fiscal years ended August 31, 1997, 1998 and 1999 were $153,486, $138,281 and
$204,621, respectively, and $15,682, $16,835 and $27,189, respectively, were
retained by John Hancock Funds in 1997, 1998 and 1999. The remainder of the
underwriting commissions were reallowed to dealers.


The Fund's  Trustees  adopted  Distribution  Plans with respect to each class of
shares (the "Plans") pursuant to Rule 12b-1 under the Investment  Company Act of
1940.  Under the Plans,  the Fund will pay  distribution  and service fees at an
aggregate  annual  rate of up to 0.30% for Class A shares  and 1.00% for Class B
and Class C shares,  of the  Fund's  average  daily net assets  attributable  to
shares of that class.  However,  the  service  fee will not exceed  0.25% of the
Fund's  average  daily net assets  attributable  to each  class of  shares.  The
distribution  fees  will  be  used  to  reimburse  John  Hancock  Funds  for its
distribution  expenses,  including  but not  limited to: (i) initial and ongoing
sales  compensation to Selling Brokers and others (including  affiliates of John
Hancock  Funds)  engaged  in  the  sale  of the  Fund  shares;  (ii)  marketing,
promotional and overhead  expenses  incurred in connection with the distribution
of Fund  shares;  and (iii)  with  respect  to Class B and Class C shares  only,
interest expenses on unreimbursed  distribution  expenses. The service fees will
be used to  compensate  Selling  Brokers and others for  providing  personal and
account  maintenance  services to  shareholders.  In the event the John  Hancock
Funds is not fully  reimbursed  for payments or expenses  they under the Class A
Plan, these expenses will not be carried beyond twelve months from the date they
were incurred. Unreimbursed expenses under the Class B and Class C Plans will be
carried  forward  together  with  interest on the balance of these  unreimbursed
expenses.  The Fund does not treat  unreimbursed  expenses under the Class B and
Class C Plans as a liability of the Fund,  because the  Trustees  may  terminate
Class B and/or Class C Plans at any time with no additional  liability for these
expenses to the  shareholders and the Fund. For the fiscal year ended August 31,
1999, an aggregate of $148,815 of distribution  expenses or 1.47% of the average
net assets of the Fund's Class B shares was not  reimbursed or recovered by John
Hancock Funds  through the receipt of deferred  sales charges or Rule 12b-1 fees
in prior  periods.  For the period  from April 1, 1999 to August  31,  1999,  an
aggregate  of $0  distribution  expenses  or 0% of the average net assets of the
Class C shares of the Fund was not reimbursed or recovered by John Hancock Funds
through receipt of deferred sales charges or 12b-1 fees.

The Plans and all amendments were approved by the Trustees, including a majority
of the  Trustees  who are not  interested  persons  of the  Fund and who have no
direct or  indirect  financial  interest  in the  operation  of the  Plans  (the
"Independent  Trustees"),  by votes  cast in person at  meetings  called for the
purpose of voting on such Plans.

Pursuant to the Plans, at least  quarterly,  John Hancock Funds provide the Fund
with a written  report of the amounts  expended  under the Plans and the purpose
for which these  expenditures  were made. The Trustees review these reports on a
quarterly basis to determine their continued appropriateness.

The Plans provide that they will continue in effect only so long as their
continuance is approved at least annually by a majority of both the Trustees and
Independent Trustees. The Plans provide that they may be terminated without
penalty, (a) by vote of a majority of the Independent Trustees, (b) by a vote of
a majority of the Fund's outstanding shares of the applicable class upon 60
days' written notice to John Hancock Funds, and (c) automatically in the event
of assignment. The Plans further provide that they may not be amended to
increase the maximum amount of the fees for the services described therein
without the approval of a majority of the outstanding shares of the class of the
Fund which has voting rights with respect to that Plan. Each Plan provides, that
no material amendment to the Plans will be effective unless it is approved by a
majority vote of the Trustees and the Independent Trustees of the Fund. The
holders of Class A, Class B and Class C shares have exclusive voting rights with
respect to the Plan applicable to their respective class of shares. In adopting
the Plans, the Trustees concluded that, in their judgment, there is a reasonable
likelihood that the Plans will benefit the holders of the applicable class of
shares of the Fund.

Amounts paid to John  Hancock  Funds by any class of shares of the Fund will not
be used to pay the expenses  incurred  with respect to any other class of shares
of the Fund;  provided,  however,  that expenses  attributable  to the Fund as a
whole will be allocated,  to the extent permitted by law, according to a formula
based upon gross  sales  dollars  and/or  average  daily net assets of each such
class,  as may be approved  from time to time by vote of a majority of Trustees.
From time to time,  the Fund may  participate in joint  distribution  activities
with other Funds and the costs of those  activities will be borne by the Fund in
proportion to the relative net asset value of the participating Fund.

During the fiscal year ended August 31, 1999,  the Fund paid John Hancock  Funds
the following amounts of expenses in connection with their services.

SALES COMPENSATION

As part of their business  strategies  the Fund,  along with John Hancock Funds,
pays compensation to financial services firms that sell the Fund's shares. These
firms  typically  pass along a portion of this  compensation  to your  financial
representative.


The two primary  sources of  compensation  payments  are )1) 12b-1 fees that are
paid out of the Fund's assets and (2) sales charges paid by investors. The sales
charges and 12b-1 fees are detailed in the  prospectus  and under  "Distribution
Contracts" in this  Statement of Additional  Information . The portions of these
expenses  that are reallowed to financial  services  firms are shown on the next
page.

Whenever  you make an  investment  in the  Fund,  the  financial  services  firm
receives a  reallowance,  as described  below.  The firm also receives the first
year's  service  fee at this  time.  Beginning  with the  second  year  after an
investment is made,  the financial  services firm receives an annual service fee
of 0.25% of its total  eligible fund net assets.  This fee is paid  quarterly in
arrears by the Fund.

In addition, from time to time, John Hancock Funds, at its expense, may provide
significant additional compensation to financial services firms which sell or
arrange for the sale of shares of the Fund. Such compensation provided by John
Hancock Funds may include, for example, financial assistance to financial
services firms in connection with their conferences or seminars, sales or
training programs for invited registered representatives and other employees,
payment for travel expenses, including lodging, incurred by registered


                                       30
<PAGE>


representatives and other employees for such seminars or training programs,
seminars for the public, advertising and sales campaigns regarding one or more
Funds, and/or other financial services firms-sponsored events or activities.
From time to time, John Hancock Funds may make expense reimbursements for
special training of a financial services firm's registered representatives and
other employees in group meetings or to help pay the expenses of sales contests.
Other compensation, such as asset retention fees, finder's fees and
reimbursement for wire transfer fees, may be offered to the extent not
prohibited by law or any self-regulatory agency, such as the NASD.

(1)   Reallowance  percentages  and service fee  percentages are calculated from
      different  amounts,   and  therefore  may  not  equal  total  compensation
      percentages if combined using simple addition.


(2) For Group  Investment  Program  sales,  the maximum total  compensation  for
 investments of $1 million or more is 1.00% of the offering price (one year CDSC
 of 1.00% applies for each sale).

CDSC  revenues  collected by John Hancock  Funds may be used to pay  commissions
when there is no initial sales charge.

Net Asset Value

For purposes of  calculating  the net asset value ("NAV") of the Fund's  shares,
the following procedures are utilized wherever applicable.

                                       32
<PAGE>


Debt investment  securities are valued on the basis of valuations furnished by a
principal  market maker or a pricing  service,  both of which generally  utilize
electronic  data  processing  techniques  to  determine  valuations  for  normal
institutional  size trading units of debt securities  without exclusive reliance
upon quoted prices.

Short-term debt investments  which have a remaining  maturity of 60 days or less
are generally  valued at amortized  cost which  approximates  market  value.  If
market  quotations are not readily available or if in the opinion of the Adviser
any  quotation or price is not  representative  of true market  value,  the fair
value  of the  security  may be  determined  in good  faith in  accordance  with
procedures approved by the Trustees.

The NAV for each fund and class is determined  each business day at the close of
regular  trading on the New York Stock  Exchange  (typically  4:00 p.m.  Eastern
Time) by dividing a class' net assets by the number of its shares outstanding.


Initial Sales Charge on Class A AND CLASS C Shares


Shares of the Fund are  offered at a price equal to their net asset value plus a
sales charge which, at the option of the purchaser, may be imposed either at the
time of purchase (the  "initial  sales charge  alternative")  or on a contingent
deferred basis (the "deferred  sales charge  alternative").  Share  certificates
will not be issued unless requested by the shareholder in writing, and then only
will be issued for full  shares.  The  Trustees  reserve  the right to change or
waive the  Fund's  minimum  investment  requirements  and to reject any order to
purchase  shares  (including  purchase by exchange)  when in the judgment of the
Adviser such rejection is in the Fund's best interest.


The sales charges applicable to purchases of Class A and Class C shares of the
Fund are described in the Prospectus. Methods of obtaining a reduced sales
charges referred to generally in the Prospectus are described in detail below.
In calculating the sales charge applicable to current purchases of Class A
shares, the investor is entitled to accumulate current purchases with the
greater of the current value (at offering price) of the Class A shares of the
Fund, owned by the investor, or if John Hancock Signature Services, Inc.
("Signature Services") is notified by the investor's dealer or the investor at
the time of the purchase, the cost of the Class A shares owned.

charge or contingent  deferred sales charge ("CDSC") to various  individuals and

                  application   approved   by  the   Securities   and   Exchange
                  Commission.



         o        Existing  full  service  clients of the Life  Company who were
                  group annuity  contract  holders as of September 1, 1994,  and
                  participant  directed  retirement  plans  with  at  least  100
                  eligible employees at the inception of the Fund account.  Each
                  of these investors may purchase Class A shares with no initial
                  sales charge.  However,  if the shares are redeemed  within 12
                  months  after  the  end of the  calendar  year  in  which  the
                  purchase  was made,  a CDSC will be imposed  at the  following
                  rate:

                  Amount Invested                            CDSC Rate
                  ---------------                            ---------

                  $1 to $4,999,999                             1.00%
                  Next $5 million to $9,999,999                0.50%
                  Amounts of $10 million and over              0.25%


Class C shares may be offered without a front-end sales charge to:

o             retirement  plans  for  which  John  Hancock  Signature   Services
              performs employer  sponsored plan recordkeeping  services.  (These
              types of plans include  401(k),  money  purchase  pension,  profit
              sharing and SIMPLE 401k.)

o             An investor who buys through a Merrill Lynch omnibus account.
              However, a CDSC may apply if the shares are sold within 12 months
              of purchase.

Class A and Class C shares may also be purchased without an initial sales charge
in  connection  with certain  liquidation,  merger or  acquisition  transactions
involving other investment companies or personal holding companies.


Combination  Privilege.  In calculating the sales charge applicable to purchases
of Class A shares  made at one time,  the  purchases  will be combined to reduce
sales charges if made by (a) an individual, his or her spouse and their children
under the age of 21, purchasing  securities for his or their own account,  (b) a
trustee or other  fiduciary  purchasing for a single trust,  estate or fiduciary
account,  and (c) groups  which  qualify for the Group  Investment  Program (see
below). A company's (not an individual's) qualified and non-qualified retirement
plan  investments can be combined to take advantage of this  privilege.  Further
information about combined purchases, including certain restrictions on combined
group  purchases,  is available  from Signature  Services or a Selling  Broker's
representative.

Accumulation Privilege. Investors (including investors combining purchases) who
are already Class A shareholders may also obtain the benefit of the reduced
sales charge by taking into account not only the amount being invested but also
the investor's purchase price or current account value of the Class A shares of
all John Hancock funds which carry a sales charge already held by such person.
Class A shares of John Hancock money market funds will only be eligible for the

                                       34
<PAGE>


accumulation privilege if the investor has previously paid a sales charge on the
amount of those shares. Retirement plan investors may include the value of Class
B shares if Class B shares held are greater than $1 million. Retirement plans
must notify Signature Services to utilize. A company's (not an individual's)
qualified and non-qualified retirement plan investments can be combined to take
advantage of this privilege.

Group Investment Program. Under the Combination and Accumulation Privileges, all
members of a group may combine their  individual  purchases of Class A shares to
potentially  qualify for breakpoints in the sales charge schedule.  This feature
is  provided  to any  group  which (1) has been in  existence  for more than six
months,  (2) has a  legitimate  purpose  other than the  purchase of mutual fund
shares at a discount for its members,  (3) utilizes salary  deduction or similar
group methods of payment, and (4) agrees to allow sales materials of the fund in
its mailings to members at a reduced or no cost to John Hancock Funds.

Letter of Intention.  Reduced sales charges are also  applicable to  investments
pursuant to a Letter of Intention  (the "LOI"),  which should be read  carefully
prior to its execution by an investor. The Fund offers two options regarding the
specified  period for making  investments  under the LOI. All investors have the
option of  making  their  investments  over a period of  thirteen  (13)  months.
Investors  who are using the Fund as a funding  medium  for a  retirement  plan,
however, may opt to make the necessary  investments called for by the LOI over a
forty-eight (48) month period. These retirement plans include traditional,  Roth
and Education IRAs, SEP,  SARSEP,  401(k),  403(b)  (including TSAs) SIMPLE IRA,
SIMPLE 401(k), Money Purchase Pension,  Profit Sharing and Section 457 plans. An
individual's  non-qualified and qualified  retirement plan investments cannot be
combined  to  satisfy  the  LOI of 48  months.  Such  an  investment  (including
accumulations  and  combinations  but not including  reinvested  dividends) must
aggregate  $100,000 or more during the specified period from the date of the LOI
or from a date within ninety (90) days prior  thereto,  upon written  request to
Signature  Services.  The sales charge  applicable to all amounts invested under
the LOI is computed as if the aggregate  amount intended to be invested had been
invested  immediately.  If such aggregate amount is not actually  invested,  the
difference in the sales charge  actually  paid and the sales charge  payable had
the LOI not been in effect is due from the investor.  However, for the purchases
actually made within the specified  period  (either 13 or 48 months),  the sales
charge  applicable  will not be  higher  than  that  which  would  have  applied
(including  accumulations  and  combinations)  had the LOI been  for the  amount
actually invested.

The LOI authorizes Signature Services to hold in escrow sufficient Class A
shares (approximately 5% of the aggregate) to make up any difference in sales
charges on the amount intended to be invested and the amount actually invested,
until such investment is completed within the specified period, at which time
the escrowed Class A shares will be released. If the total investment specified
in the LOI is not completed, the Class A shares held in escrow may be redeemed
and the proceeds used as required to pay such sales charge as may be due. By
signing the LOI, the investor authorizes Signature Services to act as his
attorney-in-fact to redeem any escrowed Class A shares and adjust the sales
charge, if necessary. A LOI does not constitute a binding commitment by an
investor to purchase, or by the subject Fund to sell, any additional Class A
shares and may be terminated at any time.

Deferred Sales Charge on Class B AND CLASS C Shares


Investments in Class B shares are purchased at net asset value per share without
the imposition of an initial sales charge so that the Fund will receive the full
amount of the purchase payment.


Contingent Deferred Sales Charge.  Class B and Class C shares which are redeemed
within six years or one year,  respectively,  of  purchase  will be subject to a
CDSC at the rates set forth in the  Prospectus  as a  percentage  of the  dollar
amount  subject to the CDSC.  The charge will be assessed on an amount  equal to
the lesser of the current  market  value or the  original  purchase  cost of the
Class B or Class C shares being  redeemed.  No CDSC will be imposed on increases
in account  value above the initial  purchase  price or on shares  derived  from
reinvestment of dividends or capital gains distributions.

Class B shares are not available to full-service  retirement plans  administered
by  Signature  Services  or the Life  Company  that had more  than 100  eligible
employees at the inception of the Fund account.

The amount of the CDSC, if any, will vary  depending on the number of years from
the  time of  payment  for the  purchase  of Class B  shares  until  the time of
redemption  of such  shares.  Solely for purposes of  determining  the number of
years from the time of any payment for the  purchase of both Class B and Class C
shares,  all payments  during a month will be aggregated and deemed to have been
made on the first day of the month.

In determining  whether a CDSC applies to a redemption,  the calculation will be
determined in a manner that results in the lowest  possible rate being  charged.
It will be assumed  that your  redemption  comes first from shares you have held
beyond  the  six-year  CDSC  redemption  period  for  Class B or one  year  CDSC
redemption  period  for  Class C, or those you  acquired  through  dividend  and
capital  gain  reinvestment,  and next from the shares you have held the longest
during the six-year period for Class B shares.  For this purpose,  the amount of
any increase in a share's value above its initial  purchase price is not subject
to a CDSC.  Thus,  when a share that has appreciated in value is redeemed during
the CDSC period, a CDSC is assessed only on its initial purchase price.

When  requesting a redemption for a specific  dollar amount,  please indicate if
you require the proceeds to equal the dollar amount requested. If not indicated,
only the  specified  dollar  amount will be redeemed  from your  account and the
proceeds will be less any applicable CDSC.

Example:


You have purchased 100 Class B shares at $10 per share. The second year after
your purchase, your investment's net asset value per share has increased by $2
to $12, and you have gained 10 additional shares through dividend reinvestment.
If you redeem 50 shares at this time your CDSC will be calculated as follows:


     oProceeds of 50 shares redeemed at $12 per shares (50 x 12)        $600.00
     o*Minus Appreciation ($12 - $10) x 100 shares                      (200.00)
     o Minus proceeds of 10 shares not subject
       to CDSC (dividend reinvestment)                                  (120.00)
                                                                        -------
     oAmount subject to CDSC                                            $280.00

*The appreciation is based on all 100 shares in the account not just the shares
being redeemed.

Proceeds from the CDSC are paid to John Hancock Funds and are used in whole or
in part by John Hancock Funds to defray its expenses related to providing
distribution-related services to the Fund in connection with the sale of the
Class B and Class C shares, such as the payment of compensation to select
Selling Brokers for selling Class B and Class C shares. The combination of the
CDSC and the distribution and service fees facilitates the ability of the Fund
to sell the Class B and Class C shares without a sales charge being deducted at
the time of the purchase.

If you qualify for a CDSC waiver under one of these situations,  you must notify
Signature  Services  at the time you make your  redemption.  The waiver  will be
granted  once  Signature  Services  has  confirmed  that you are entitled to the
waiver.

Special Redemptions

Although  it  would  not  normally  do so,  the  Fund  has the  right to pay the
redemption  price  of  shares  of the  Fund in  whole  or in  part in  portfolio
securities as prescribed by the Trustees.  When the shareholder  sells portfolio
securities  received in this  fashion,  the  shareholder  will incur a brokerage
charge.  Any such  securities  would be valued for the  purpose  of making  such
payment at the same value as used in determining the Fund's net asset value. The
Fund has,  however,  elected to be governed  by Rule 18f-1 under the  Investment
Company Act. Under that rule, the Fund must redeem its shares for cash except to
the extent that the  redemption  payments to any  shareholder  during any 90-day
period  would  exceed the lesser of $250,000 or 1% of the Fund's net asset value
at the beginning of such period.

Additional Services And Programs

Exchange Privilege.  The Fund permits exchanges of shares of any class of a fund
for shares of the same class in any other John Hancock fund offering that class.

Exchanges  between funds with shares that are not subject to a CDSC are based on
their  respective net asset values.  No sales charge or  transactions  charge is
imposed.  Shares of the Fund which are subject to a CDSC may be  exchanged  into
shares of any of the other John Hancock funds that are subject to a CDSC without
incurring the CDSC; however,  the shares acquired in an exchange will be subject
to the CDSC schedule of the shares acquired if and when such shares are redeemed
(except that shares  exchanged into John Hancock 500 Index Fund and John Hancock
Intermediate  Government  Fund will retain the exchanged  fund's CDSC schedule).
For purposes of computing the CDSC payable upon redemption of shares acquired in
an exchange,  the holding period of the original  shares is added to the holding
period of the shares acquired in an exchange.

If a shareholder exchanges Class B shares purchased prior to January 1, 1994 for
Class B shares of any other John Hancock fund, the acquired shares will continue
to be subject to the CDSC schedule that was in effect when the exchanged  shares
were purchased.

The Fund  reserves the right to require that  previously  exchanged  shares (and
reinvested  dividends)  be in the  Fund  for 90 days  before  a  shareholder  is
permitted a new exchange.

The Fund may  refuse  any  exchange  order.  The Fund may  change or cancel  its
exchange policies at any time, upon 60 days' notice to its shareholders.

An exchange of shares is treated as a  redemption  of shares of one fund and the
purchase of shares of another for Federal  Income Tax purposes.  An exchange may
result in a taxable gain or loss. See "TAX STATUS".

Systematic Withdrawal Plan. The Fund permits the establishment of a Systematic
Withdrawal Plan. Payments under this plan represent proceeds arising from the
redemption of Fund shares, which may result in realization of gain or loss for
purposes of Federal, state and local income taxes. The maintenance of a
Systematic Withdrawal Plan concurrently with purchases of additional shares of
the Fund could be disadvantageous to a shareholder because of the initial sales
charge payable on the purchases of Class A shares and the CDSC imposed on
redemptions of Class B and Class C shares and because redemptions are taxable
events. Therefore, a shareholder should not purchase shares at the same time as
a Systematic Withdrawal Plan is in effect. The Fund reserves the right to modify
or discontinue the Systematic Withdrawal Plan of any shareholder on 30 days'
prior written notice to such shareholder, or to discontinue the availability of
such plan in the future. The shareholder may terminate the plan at any time by
giving proper notice to Signature Services.

                                       40
<PAGE>


Monthly Automatic Accumulation Program ("MAAP"). The program is explained in the
Prospectus. The program, as it relates to automatic investment checks, is
subject to the following conditions:

The investment will be drawn on or about the day of the month indicated.

The privilege of making investments through the MAAP may be revoked by Signature
Services  without  prior  notice  if  any  investment  is  not  honored  by  the
shareholder's  bank.  The  bank  shall  be under no  obligation  to  notify  the
shareholder as to the non-payment of any checks.

The program may be discontinued by the shareholder  either by calling  Signature
Services or upon written notice to Signature Services which is received at least
five (5) business days prior to the order date of any investment.

Reinstatement  and  Reinvestment  Privilege.  If Signature  Services is notified
prior to  reinvestment,  a shareholder  who has redeemed Fund shares may, within
120 days  after the date of  redemption,  reinvest  without  payment  of a sales
charge any part of the  redemption  proceeds  in shares of the same class of the
Fund or another John Hancock fund,  subject to the minimum  investment  limit of
that fund.  The proceeds from the redemption of Class A shares may be reinvested
at net asset value  without  paying a sales charge in Class A shares of any John
Hancock fund. If a CDSC was paid upon a redemption,  a shareholder  may reinvest
the proceeds from this redemption at net asset value in additional shares of the
class from which the  redemption  was made.  The  shareholder's  account will be
credited with the amount of the CDSC charged upon the prior  redemption  and the
new shares will  continue to be subject to the CDSC.  The holding  period of the
shares acquired  through  reinvestment  will, for purposes of computing the CDSC
payable upon a subsequent redemption, include the holding period of the redeemed
shares.

To protect the interests of other investors in the Fund, the Fund may cancel the
reinvestment  privilege  of any parties  that,  in the opinion of the Fund,  are
using market timing  strategies or making more than seven exchanges per owner or
controlling  party per calendar year. Also, the Fund may refuse any reinvestment
request.

The Fund may change or cancel its reinvestment policies at any time.

A  redemption  or exchange of Fund shares is a taxable  transaction  for Federal
income tax purposes even if the  reinvestment  privilege is  exercised,  and any
gain or loss realized by a shareholder on the redemption or other disposition of
Fund shares will be treated for tax purposes as described under the caption "TAX
STATUS."

Retirement Plans participating in Merrill Lynch's servicing programs.

Class A shares  are  available  at net asset  value for plans with $3 million in
plan assets or 500 eligible  employees  at the date the Plan  Sponsor  signs the
Merrill Lynch Recordkeeping Service Agreement.  If the plan does not meet either
of these limits, Class A shares are not available.

For  participating  retirement  plans  investing in Class B shares,  shares will
convert  to Class A shares  after  eight  years,  or sooner if the plan  attains
assets of $5 million (by means of a CDSC-free  redemption/purchase  at net asset
value).

PURCHASES AND REDEMPTIONS THROUGH THIRD PARTIES

Shares of the Fund may be purchased or redeemed through certain  broker-dealers.
Brokers  may charge for their  services  or place  limitations  on the extent to
which  you may use the  services  of the  Fund.  The Fund will be deemed to have
received  a  purchase  or  redemption  order when an  authorized  broker,  or if
applicable,  a broker's authorized designee,  receives the order. If a broker is
an  agent  or  designee  of the  Fund,  orders  are  processed  at the NAV  next
calculated  after the broker  receives the order.  The broker must segregate any
orders it  receives  after the close of  regular  trading  on the New York Stock
Exchange  and  transmit  those  orders  to the  Fund for  execution  at NAV next
determined.  Some brokers that maintain nominee accounts with the Fund for their
clients charge an annual fee on the average net assets held in such accounts for
accounting,  servicing,  and distribution  services they provide with respect to
the underlying Fund shares. The Adviser,  the Fund, and John Hancock Funds, Inc.
(the Fund's principal distributor), share in the expense of these fees.

Description Of The Fund's Shares

The Trustees of the Trust are  responsible for the management and supervision of
the Fund.  The  Declaration  of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of the Fund, without
par value.  Under the  Declaration of Trust,  the Trustees have the authority to
create and classify shares of beneficial interest in separate series and classes
without  further  action by  shareholders.  As of the date of this  Statement of
Additional Information,  the Trustees have authorized the issuance of two series
of shares - John Hancock Massachusetts Tax-Free Income Fund and the John Hancock
New York Tax-Free Income Fund. Additional series may be added in the future. The
Trustees  have also  authorized  the issuance of three classes of shares of each
series, designated as Class A, Class B and Class C.

The shares of each class of the Fund represent an equal  proportionate  interest
in the  aggregate net assets  attributable  to that class or series of the Fund.
Holders of each class of shares have certain  exclusive voting rights on matters
relating to their respective  distribution  plans. The different  classes of the
Fund may bear  different  expenses  relating to the cost of holding  shareholder
meetings necessitated by the exclusive voting rights of any class of shares.

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 on the same day and will be
in the same amount, except for differences resulting from the facts that (i) the
distribution  and  service  fees  relating to each class of shares will be borne
exclusively  by that  class  (ii)  Class B and  Class C shares  will pay  higher
distribution and service fees than Class A shares and (iii) each class of shares
will bear any class expenses properly allocable to that class of shares, subject
to the  conditions  the  Internal  Revenue  Service  imposes with respect to the
multiple-class  structures.  Similarly,  the net asset  value per share may vary
depending on which class of shares are  purchased.  No interest  will be paid on
uncashed dividend or redemption checks.

In the event of  liquidation,  shareholders  of each class are entitled to share
pro rata in the net  assets  of the Fund  available  for  distribution  to these
shareholders.  Shares  entitle their  holders to one vote per share,  are freely
transferable  and have no preemptive,  subscription or conversion  rights.  When
issued,  shares are fully  paid and  non-assessable  by the Fund,  except as set
forth below.

Unless otherwise required by the Investment Company Act or the Declaration of
Trust, the Fund has no intention of holding annual meetings of shareholders. The
Fund's shareholders may remove a Trustee by the affirmative vote of at least
two-thirds of the Fund's outstanding shares and the Trustees shall promptly call
a meeting for such purpose when requested to do so in writing by the record
holders of not less than 10% of the outstanding shares of the Fund. Shareholders
may, under certain circumstances, communicate with other shareholders in
connection with requesting a special meeting of shareholders. However, at any
time that less than a majority of the Trustees holding office were elected by
the shareholders, the Trustees will call a special meeting of shareholders for
the purpose of electing Trustees.

Under Massachusetts law,  shareholders of a Massachusetts  business trust could,
under certain  circumstances,  be held personally liable for acts or obligations
of the Trust.  However,  the Fund's  Declaration  of Trust  contains  an express
disclaimer  of  shareholder  liability for acts,  obligations  or affairs of the
Fund.  The  Declaration  of Trust also provides for  indemnification  out of the
Fund's  assets for all losses and expenses of any  shareholder  of any Fund held
personally  liable  by  reason  of  being  or  having  been a  shareholder.  The
Declaration  of Trust also  provides  that no series of the Fund shall be liable
for the liabilities of any other series.  Furthermore,  no fund included in this
Fund's  Prospectus shall be liable for the liabilities of any other John Hancock
fund.  Liability is therefore  limited to circumstances in which the Fund itself
would be unable to meet its obligations,  and the possibility of this occurrence
is remote.

The Fund reserves the right to reject any  application  which conflicts with the
Fund's  internal  policies or the  policies of any  regulatory  authority.  John
Hancock Funds does not accept  starter,  credit card or third party checks.  All
checks  returned by the post office as  undeliverable  will be reinvested at net
asset  value in the fund or funds from which a  redemption  was made or dividend
paid.  Information  provided on the account application may be used by the Funds
to verify the accuracy of the information or for background or financial history
purposes.  A joint account will be administered as a joint tenancy with right of
survivorship,  unless the joint owners notify Signature  Services of a different
intent.  A shareholder's  account is governed by the laws of The Commonwealth of
Massachusetts. For telephone transactions, the transfer agent will take measures
to verify the identity of the caller,  such as asking for name,  account number,
Social Security or other taxpayer ID number and other relevant  information.  If
appropriate  measures are taken,  the transfer agent is not  responsible for any
losses that may occur to any account due to an unauthorized telephone call. Also
for your protection  telephone  transactions are not permitted on accounts whose
names or addresses have changed within the past 30 days. Proceeds from telephone
transactions can only be mailed to the address of record.

Selling activities for the Fund may not take place outside the U.S. except with
U.S. military bases, APO addresses and U.S. diplomats. Brokers of record on
Non-U.S. investors' accounts with foreign mailing addresses are required to
certify that all sales activities have occurred, and in the future will occur,
only in the U.S. A foreign corporation may purchase shares of the Fund only if
it has a U.S. mailing address.

Tax Status

Federal Income Taxation

 The Fund is treated as a separate  entity for accounting and tax purposes,  has
qualified and elected to be treated as a "regulated  investment  company"  under
Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"),  and
intends to so qualify for each taxable year.  As such and by complying  with the
applicable  provisions  of the Code  regarding  the sources of its  income,  the
timing of its  distributions,  and the  diversification  of its assets, the Fund
will not be subject to Federal income tax on its tax-exempt interest and taxable
income   (including  net  realized   capital  gains)  which  is  distributed  to
shareholders in accordance with the timing requirements of the Code.

                                       43

The Fund will be subject to a 4%  non-deductible  Federal  excise tax on certain
amounts not distributed (and not treated as having been distributed) on a timely
basis in accordance  with annual  minimum  distribution  requirements.  The Fund
intends under normal  circumstances  to seek to avoid or minimize  liability for
such tax by satisfying such distribution requirements.

The Fund expects to qualify to pay  "exempt-interest  dividends,"  as defined in
the Code.  To qualify to pay  exempt-interest  dividends,  the Fund must, at the
close of each quarter of its taxable year, have at least 50% of the value of its
total assets  invested in municipal  securities  whose interest is excluded from
gross  income  under  Section  103(a)  of  the  Code.  In  purchasing  municipal
securities,  the Fund intends to rely on opinions of nationally  recognized bond
counsel for each issue as to the  excludability  of interest on such obligations
from gross  income for  federal  income tax  purposes  and,  if  available,  the
exemption of such interest from Massachusetts personal income tax. The Fund will
not undertake  independent  investigations  concerning the tax-exempt  status of
such  obligations,  nor does it  guarantee  or  represent  that  bond  counsels'
opinions are correct.  Bond  counsels'  opinions will generally be based in part
upon  covenants  by  the  issuers  and  related  parties  regarding   continuing
compliance with federal tax requirements.  Tax laws enacted  principally  during
the 1980's not only had the effect of limiting the purposes for which tax-exempt
bonds could be issued and reducing the supply of such bonds,  but also increased
the number and complexity of requirements that must be satisfied on a continuing
basis in order for bonds to be and remain tax-exempt. If the issuer of a bond or
a user of a bond-financed facility fails to comply with such requirements at any
time,  interest on the bond could become  taxable,  retroactive  to the date the
obligation  was  issued.  In that event,  a portion of the Fund's  distributions
attributable to interest the Fund received on such bond for the current year and
for prior years could be characterized or recharacterized as taxable income. The
availability of tax-exempt obligations and the value of the Fund's portfolio may
be affected by  restrictive  federal  income tax  legislation  enacted in recent
years or by similar future legislation.

If the Fund  satisfies the applicable  requirements,  dividends paid by the Fund
which are  attributable  to tax exempt  interest  on  municipal  securities  and
designated by the Fund as  exempt-interest  dividends in a written notice mailed
to its shareholders within sixty days after the close of its taxable year may be
treated by shareholders as items of interest  excludable from their gross income
under Section 103(a) of the Code. The recipient of tax-exempt income is required
to report such income on his federal income tax return.  However,  a shareholder
is advised to consult his tax adviser  with  respect to whether  exempt-interest
dividends retain the exclusion under Section 103(a) if such shareholder would be
treated as a "substantial user" or "related person" thereof under Section 147(a)
with respect to any of the  tax-exempt  obligations  held by the Fund.  The Code
provides  that  interest on  indebtedness  incurred or  continued to purchase or
carry shares of the Fund is not deductible to the extent it is deemed related to
the Fund's  exempt-interest  dividends.  Pursuant to published  guidelines,  the
Internal  Revenue  Service may deem  indebtedness  to have been incurred for the
purpose of  purchasing  or carrying  shares of the Fund even though the borrowed
money may not be directly traceable to the purchase of shares.

Although all or a substantial portion of the dividends paid by the Fund may be
excluded by the Fund's shareholders from their gross income for federal income
tax purposes, the Fund may purchase specified private activity bonds, the
interest from which (including the Fund's distributions attributable to such
interest) may be a preference item for purposes of the federal alternative
minimum tax (both individual and corporate). All exempt-interest dividends from
the Fund, whether or not attributable to private activity bond interest, may
increase a corporate shareholder's liability, if any, for corporate alternative
minimum tax and will be taken into account in determining the extent to which a
shareholder's Social Security or certain railroad retirement benefits are
taxable.

                                       44
<PAGE>


Distributions  other than  exempt-interest  dividends from the Fund's current or
accumulated  earnings  and profits  ("E&P")  will be taxable  under the Code for
investors who are subject to tax. Taxable  distributions  include  distributions
from the Fund that are  attributable  to (i) taxable  income,  including but not
limited to taxable bond interest,  recognized  market discount income,  original
issue  discount  income  accrued  with  respect to taxable  bonds,  income  from
repurchase agreements, income from securities lending, income from dollar rolls,
income from interest rate swaps, caps, floors and collars,  and a portion of the
discount from certain stripped tax- exempt  obligations or their coupons or (ii)
capital  gains  from  the  sale or  constructive  sale of  securities  or  other
investments  (including from the disposition of rights to when-issued securities
prior to issuance) or from options and futures contracts. If these distributions
are paid from the  Fund's  "investment  company  taxable  income,"  they will be
taxable as ordinary  income;  and if they are paid from the Fund's "net  capital
gain," they will be taxable as long-term  capital gain. (Net capital gain is the
excess (if any) of net long-term capital gain over net short-term  capital loss,
and investment company taxable income is all taxable income and capital gains or
losses,  other than those  gains and losses  included in  computing  net capital
gain, after reduction by deductible expenses.) Some distributions may be paid in
January  but may be  taxable to  shareholders  as if they had been  received  on
December 31 of the previous year. The tax treatment  described  above will apply
without  regard to whether  distributions  are received in cash or reinvested in
additional shares of the Fund.

Distributions,  if any,  in excess of E&P will  constitute  a return of  capital
under the Code, which will first reduce an investor's  federal tax basis in Fund
shares and then, to the extent such basis is exceeded,  will generally give rise
to capital  gains.  Amounts  that are not  allowable as a deduction in computing
taxable income,  including expenses  associated with earning tax-exempt interest
income,  do not  reduce  the  Fund's  current  earnings  and  profits  for these
purposes.  Consequently,  the portion, if any, of the Fund's  distributions from
gross tax-exempt  interest income that exceeds its net tax-exempt interest would
be taxable as ordinary income to the extent of such  disallowed  deductions even
though  such  excess  portion  may  represent  an  economic  return of  capital.
Shareholders who have chosen automatic  reinvestment of their distributions will
have a federal tax basis in each share received  pursuant to such a reinvestment
equal to the amount of cash they would have received had they elected to receive
the  distribution  in cash,  divided  by the  number of shares  received  in the
reinvestment.

After the close of each calendar year, the Fund will inform  shareholders of the
federal  income tax status of its  dividends  and  distributions  for such year,
including the portion of such  dividends  that  qualifies as tax-exempt  and the
portion, if any, that should be treated as a tax preference item for purposes of
the federal  alternative  minimum tax.  Shareholders who have not held shares of
the Fund for its full taxable year may have designated as tax-exempt or as a tax
preference item a percentage of  distributions  which is not equal to the actual
amount of a pro rata share of tax-exempt  income or tax  preference  item income
earned by the Fund during the period of their investment in the Fund.

The amount of the Fund's net realized capital gains, if any, in any given year
will vary depending upon the Adviser's current investment strategy and whether
the Adviser believes it to be in the best interest of the Fund to dispose of
Fund securities and/or engage in options or futures transactions that will
generate capital gains. At the time of an investor's purchase of the Fund's
shares, a portion of the purchase price is often attributable to realized or
unrealized appreciation in the Fund's portfolio. Consequently, subsequent
distributions on these shares from such appreciation may be taxable to such
investor even if the net asset value of the investor's shares is, as a result of
the distributions, reduced below the investor's cost for such shares, and the
distributions in reality represent a return of a portion of the purchase price.

                                       45

Upon a  redemption  or other  disposition  of shares of the Fund  (including  by
exercise of the exchange  privilege) in a transaction  that is treated as a sale
for tax purposes,  a shareholder will ordinarily  realize a taxable gain or loss
depending  upon the  amount  of the  proceeds  and the  investor's  basis in his
shares.  Such gain or loss will be treated as capital gain or loss if the shares
are capital assets in the shareholder's hands. A sales charge paid in purchasing
shares of a Fund cannot be taken into account for purposes of  determining  gain
or loss on the  redemption or exchange of such shares within 90 days after their
purchase  to the extent  shares of the Fund or  another  John  Hancock  Fund are
subsequently  acquired  without  payment  of a  sales  charge  pursuant  to  the
reinvestment or exchange  privilege.  This disregarded  charge will result in an
increase in the  shareholder's  tax basis in the shares  subsequently  acquired.
Also,  any loss  realized on a redemption  or exchange may be  disallowed to the
extent the shares  disposed of are replaced with other shares of the Fund within
a period of 61 days beginning 30 days before and ending 30 days after the shares
are disposed of, such as pursuant to automatic dividend reinvestments. In such a
case,  the  basis  of the  shares  acquired  will be  adjusted  to  reflect  the
disallowed loss.

Any loss realized upon the redemption of shares with a tax holding period of six
months or less will be disallowed to the extent of all exempt-interest dividends
paid with  respect  to such  shares  and,  to the extent in excess of the amount
disallowed,  will be treated as a  long-term  capital  loss to the extent of any
amounts treated as distributions of long-term  capital gain with respect to such
shares.  Shareholders  should  consult  their own tax advisers  regarding  their
particular  circumstances  to determine  whether a disposition of Fund shares is
properly  treated as a sale for tax  purposes,  as is  assumed in the  foregoing
discussion.

Although its present  intention is to  distribute,  at least  annually,  all net
capital  gain, if any, the Fund reserves the right to retain and reinvest all or
any  portion of the excess of net  long-term  capital  gain over net  short-term
capital  loss in any year.  The Fund  will not,  in any  event,  distribute  net
capital  gain  realized in any year to the extent that a capital loss is carried
forward  from prior  years  against  such gain.  To the extent  such  excess was
retained and not exhausted by the  carryforward  of prior years' capital losses,
it would be subject to federal income tax in the hands of the Fund.  Upon proper
designation of this amount by the Fund,  each  shareholder  would be treated for
Federal  income tax purposes as if the Fund had  distributed  to him on the last
day of its taxable year his pro rata share of such  excess,  and he had paid his
pro rata share of the taxes paid by the Fund and reinvested the remainder in the
Fund. Accordingly, each shareholder would (a) include his pro rata share of such
excess as long-term capital gain in his return for his taxable year in which the
last day of the Fund's  taxable  year  falls,  (b) be  entitled  either to a tax
credit on his  return  for,  or to a refund  of, his pro rata share of the taxes
paid by the Fund and (c) be entitled to increase  the adjusted tax basis for his
shares in the Fund by the  difference  between his pro rata share of such excess
and his pro rata share of such taxes.

For Federal  income tax  purposes,  the Fund is permitted to carry forward a net
capital loss in any year to offset its own net capital gains, if any, during the
eight years  following  the year of the loss. To the extent  subsequent  capital
gains are offset by such  losses,  they  would not result in federal  income tax
liability  to the  Fund  and,  as  noted  above,  would  not be  distributed  to
shareholders.  The Fund has a realized capital loss carryforward of $185,328, of
which $41,406 expires  8/31/2003,  $137,277 expires 8/31/2004 and $6,645 expires
8/31/2005.

The Fund is required to accrue original issue discount ("OID") on certain debt
securities (including zero coupon or deferred payment obligations) that have OID
prior to the receipt of the corresponding cash payments. The mark to market or
constructive sale rules applicable to certain options and futures contracts or
other transactions may also require the Fund to recognize income or gain without
a concurrent receipt of cash. However, the Fund must distribute to shareholders
for each taxable year substantially all of its net income and net capital gains,
including such income or gain, to qualify as a regulated investment company and
avoid liability for any federal income or excise tax. Therefore, the Fund may
have to dispose of its portfolio securities under disadvantageous circumstances
to generate cash, or borrow the cash, to satisfy these distribution
requirements.

                                       46
<PAGE>


The Federal income tax rules applicable to certain structured or indexed
securities, interest rate swaps, caps, floors and collars, dollar rolls and
possibly other investments or transactions, are unclear in certain respects, and
the Fund will account for these investments or transactions in a manner intended
to preserve its qualification as a regulated investment company and avoid
material tax liability.

The Fund will be required to report to the Internal  Revenue Service (the "IRS")
all taxable  distributions to  shareholders,  as well as gross proceeds from the
redemption  or exchange  of Fund  shares,  except in the case of certain  exempt
recipients,  i.e.,  corporations  and certain other investors  distributions  to
which are exempt from the information  reporting  provisions of the Code.  Under
the backup withholding  provisions of Code Section 3406 and applicable  Treasury
regulations,  all such reportable  distributions  and proceeds may be subject to
backup  withholding  of  federal  income  tax at the  rate of 31% in the case of
non-exempt shareholders who fail to furnish the Fund with their correct taxpayer
identification number and certain  certifications  required by the IRS or if the
IRS or a broker  notifies the Fund that the number  furnished by the shareholder
is  incorrect  or that the  shareholder  is subject to backup  withholding  as a
result of failure to report  interest or dividend  income.  However,  the Fund's
taxable  distributions may not be subject to backup  withholding if the Fund can
reasonably  estimate that at least 95% of its distributions for the year will be
exempt-interest  dividends.  The Fund may refuse to accept an  application  that
does not contain any required  taxpayer  identification  number or certification
that the number provided is correct.  If the backup  withholding  provisions are
applicable,  any  such  distributions  and  proceeds,  whether  taken in cash or
reinvested  in shares,  will be reduced by the amounts  required to be withheld.
Any amounts withheld may be credited against a shareholder's U.S. federal income
tax   liability.   Investors   should  consult  their  tax  advisers  about  the
applicability of the backup withholding provisions.

The Fund may invest in debt obligations that are in the lower rating  categories
or are  unrated.  Investments  in debt  obligations  that are at risk of default
present  special tax issues for the Fund. Tax rules are not entirely clear about
issues  such as when the  Fund may  cease to  accrue  interest,  original  issue
discount,  or market discount,  when and to what extent  deductions may be taken
for bad debts or worthless  securities,  how payments received on obligations in
default should be allocated between principal and income,  and whether exchanges
of debt  obligations  in a workout  context are taxable.  If the Fund invests in
these debt obligations,  it will address these issues in order to seek to ensure
that it  distributes  sufficient  income to  preserve  its status as a regulated
investment  company  and seek to avoid  becoming  subject to  Federal  income or
excise tax.

Dividends and capital gain  distributions  paid by the Fund will not qualify for
the dividends-received deduction for corporate shareholders.

Limitations imposed by the Code on regulated  investment companies like the Fund
may restrict the Fund's ability to enter into futures and options transactions.

Certain options and futures transactions undertaken by the Fund may cause the
Fund to recognize gains or losses from marking to market even though its
positions have not been sold or terminated and affect the character as long-term
or short-term and timing of some capital gains and losses realized by the Fund.
Additionally, the Fund may be required to recognize gain (subject to tax
distribution requirements) if an option, future, notional principal contract, or
a combination thereof is treated as a constructive sale of an appreciated
financial position in the Fund's portfolio. Also, certain of the Fund's losses
on its transactions involving options or futures contracts and/or offsetting or

                                       47
<PAGE>


successor Fund positions may be deferred rather than being taken into account
currently in calculating the Fund's taxable income or gain. Some of these
transactions may also cause the Fund to dispose of investments sooner than would
otherwise have occurred. These transactions may therefore affect the amount,
timing and character of the Fund's distributions to shareholders. The Fund will
take into account the special tax rules (including consideration of available
elections) applicable to options and futures transactions in order to seek to
minimize any potential adverse tax consequences.

The  foregoing  discussion  relates  solely to U.S.  Federal  income  tax law as
applicable to U.S. persons (i.e.,  U.S.  citizens or residents and U.S. domestic
corporations,  partnerships,  trusts or estates)  subject to tax under such law.
Dividends (including exempt-interest dividends), capital gain distributions, and
ownership of or gains realized on the redemption (including an exchange) of Fund
shares may also be subject to state and local taxes,  except as described  below
under "State Income Tax  Information."  The discussion  does not address special
tax rules applicable to certain types of investors,  such as insurance companies
and financial  institutions.  Shareholders should consult their own tax advisers
as to the Federal,  state or local tax  consequences  of ownership of shares of,
and receipt of distributions from, the Fund in their particular circumstances.

Non-U.S.  investors  not engaged in a U.S.  trade or  business  with which their
investment in the Fund is effectively  connected will be subject to U.S. Federal
income tax treatment different from that described above. These investors may be
subject to  non-resident  alien  withholding  tax at the rate of 30% (or a lower
rate under an applicable  tax treaty) on amounts  treated as ordinary  dividends
from a Fund and,  unless an effective IRS Form W-8,  W-8BEN or other  authorized
withholding  certificate is on file, to 31% backup  withholding on certain other
payments from the Fund.  Non-U.S.  investors  should  consult their tax advisers
regarding such  treatment and the  application of foreign taxes to an investment
in the Fund.

STATE INCOME TAX INFORMATION

MASSACHUSETTS TAXES

The Fund is not subject to  Massachusetts  corporate  excise or franchise taxes.
The Fund  anticipates  that,  provided  that the Fund  qualifies  as a regulated
investment  company  under the Code,  it will  also not be  required  to pay any
Massachusetts income tax.

To the extent that exempt-interest dividends paid to shareholders by the Fund
are derived from interest on tax-exempt bonds of the Commonwealth of
Massachusetts and its political subdivisions or Puerto Rico, the U.S. Virgin
Islands or Guam and are properly designated as such, these distributions will be
exempt from Massachusetts personal income tax. For Massachusetts personal income
tax purposes, dividends from the Fund's taxable net investment income,
tax-exempt income from obligations not described in the preceding sentence, and
short-term capital gains, if any, will generally be taxable as ordinary income,
whether received in cash or additional shares. However, any dividends that are
properly designated as attributable to interest the Fund receives on direct U.S.
Government obligations will not be subject to Massachusetts personal income tax.
Dividends properly designated as from net capital gain are generally taxable as
long-term capital gains, regardless of how long shareholders have held their
Fund shares. However, a portion of such a long-term capital gains distribution
will be exempt from Massachusetts personal income tax if it is properly
designated as attributable to gains realized on the sale of certain tax-exempt
bonds issued pursuant to Massachusetts statutes that specifically exempt such
gains from Massachusetts taxation. Dividends from investment income (including
exempt- interest dividends) and from capital gains will be subject to, and
shares of the Fund will be included in the net worth of intangible property
corporations for purposes of, the Massachusetts corporation excise tax if
received by a corporation subject to such tax.

                                       48
<PAGE>


For personal  income tax  purposes,  long-term  capital gains from the sale of a
capital asset are generally taxed on a sliding scale at rates ranging from 5% to
0%, with the  applicable  tax rate  declining  as the tax holding  period of the
asset  (beginning  on the  later  of  January  1,  1995 or the  date  of  actual
acquisition)  increases  from  more  than  one  year to  more  than  six  years.
Massachusetts  resident  individuals,  as well as  estates  or  personal  trusts
subject to Massachusetts income taxation, are subject to this tax structure with
respect to redemption,  exchanges or other  dispositions  of their shares of the
Fund,  assuming  that they hold their  shares of the Fund as capital  assets for
Massachusetts tax purposes.  The applicable statutory provision does not address
the  Massachusetts  tax  treatment  of  dividends  paid  by the  Fund  that  are
designated  and  treated  as  long-term  capital  gains for  Federal  income tax
purposes.  The  Massachusetts  Department  of Revenue  (the "DOR") has  proposed
regulations under which this distribution  would be taxed at the maximum 5% rate
unless a mutual fund reports to the DOR and the shareholder  within a prescribed
time  period the  portions  of the  distribution  attributable  to gains in each
separate holding period category, in which case each such portion would be taxed
at the rate  applicable to the  appropriate  holding period  category.  The Fund
anticipates  that, to the extent  practicable,  it will provide the  appropriate
information  under  the  applicable  DOR  regulations  or  other  administrative
positions.

CALCULATION OF PERFORMANCE

For the 30-day  period  ended  August 31, 1999,  the  annualized  yields for the
Fund's  Class A,  Class B and  Class C shares  were  4.59%,  4.10%  and  4.07% ,
respectively.  The average annual total returns of the Fund's Class A shares for
the 1 year,  5 years and the  life-of-fund  periods  ended  August 31, 1999 were
- -5.32 %, 5.17% and 6.50%, respectively. The total returns for Class B shares for
the one year  period  and since  inception  on  October 3, 1996 were -6.28 % and
- -3.89%,  respectively.  For Class C shares for the period  from April 1, 1999 to
August 31, 1999, the average total returns were -4.10%. Class C shares commenced
operations on April 1, 1999; therefore, there are no other periods to report.

The Fund may advertise yield, where appropriate. The Fund's yield is computed by
dividing net investment  income per share  determined for a 30-day period by the
maximum  offering price per share (which  includes the full sales charge) on the
last day of the period, according to the following standard formula:

                                               6
                  Yield = 2 ( [ ( a - b ) + 1 ] - 1 )
                                 -------
                                   cd
Where:

         a=       dividends and interest earned during the period.
         b=       net expenses accrued during the period.
         c=       the average daily number of fund shares outstanding during the
                  period that would be entitled to receive dividends.
         d=       the maximum offering price per share on the last day of the
                  period (NAV where applicable).

                                       49
<PAGE>


The Fund may  advertise a  tax-equivalent  yield,  which is computed by dividing
that portion of the yield of the Fund which is  tax-exempt by one minus a stated
income tax rate and adding the product to that portion,  if any, of the yield of
the Fund that is not tax-exempt.  The tax equivalent yields for the Fund's Class
A and Class B shares at the  combined  maximum  federal  and  Massachusetts  tax
rates, which assumes the full deductibility of state income taxes on the federal
income tax return,  for the 30-day  period  ended August 31, 1999 were 8.08% and
7.22%,  respectively.  The tax equivalent yield for the Fund's Class C shares at
the combined maximum federal and Massachusetts tax rates,  which assume the full
deductibility  of state income  taxes on the federal tax return,  for the period
ended August 31, 1999 was 7.17%.

Total return is computed by finding the average annual compounded rate of return
over the 1 year,  5 year and  life-of-fund  period that would equate the initial
amount  invested  to the ending  redeemable  value  according  to the  following
formula:

               n ______
          T = \ / ERV/P - 1

Where:

P =       a hypothetical initial investment of $1,000.
T =       average annual total return.
n =       number of years.
ERV =     ending redeemable value of a hypothetical $1,000 investment made at
          the beginning of the 1-year and life-of-fund periods.

Because each class has its own sales charge and fee structure,  the classes have
different  performance  results.  In the case of each  class,  this  calculation
assumes the maximum  sales charge is included in the initial  investment  or the
CDSC  applied  at the end of the  period.  This  calculation  assumes  that  all
dividends  and   distributions   are  reinvested  at  net  asset  value  on  the
reinvestment dates during the period.  The "distribution  rate" is determined by
annualizing the result of dividing the declared dividends of the Fund during the
period stated by the maximum offering price or net asset value at the end of the
period.  Excluding the Fund's sales charge from the distribution rate produces a
higher rate.

In addition to average  annual total returns,  the Fund may quote  unaveraged or
cumulative total returns  reflecting the simple change in value of an investment
over a stated period.  Cumulative total returns may be quoted as a percentage or
as a dollar amount, and may be calculated for a single  investment,  a series of
investments, and/or a series of redemptions, over any time period. Total returns
may be quoted with or without  taking the Fund's  sales charge on Class A shares
or the CDSC on Class B or Class C shares  into  account.  Excluding  the  Fund's
sales  charge on Class A shares and the CDSC on Class B or Class C shares from a
total return calculation produces a higher total return figure.

In the case of a tax-exempt obligation issued without original issue discount
and having a current market discount, the coupon rate of interest is used in
lieu of the yield to maturity. Where, in the case of a tax-exempt obligation
with original issue discount, the discount based on the current market value
exceeds the then-remaining portion or original issue discount (market discount),
the yield to maturity is the imputed rate based on the original issue discount
calculation. Where, in the case of a tax-exempt obligation with original issue
discount, the discount based on the current market value is less than the
then-remaining portion of original issue discount (market premium), the yield to
maturity is based on the market value.

From time to time, in reports and promotional  literature,  the Fund's yield and
total  return  will be  compared  to  indices of mutual  funds and bank  deposit
vehicles such as Lipper Analytical Services,  Inc.'s "Lipper - Fixed Income Fund
Performance  Analysis," a monthly  publication  which  tracks net assets,  total
return,  and yield on fixed income mutual funds in the United  States.  Ibottson
and Associates,  CDA  Weisenberger  and F.C. Towers are also used for comparison
purposes as well as the Russell and Wilshire  Indices.  Comparisons  may also be
made to bank certificates of deposit,  ("CDs") which differ from mutual funds in
several ways. The interest rate  established by the sponsoring bank is fixed for
the term of a CD, there are  penalties  for early  withdrawal  from CDs, and the
principal on a CD is insured.

Performance  rankings and ratings  reported  periodically in, and excerpts from,
national financial  publication such as MONEY MAGAZINE,  FORBES,  BUSINESS WEEK,
THE WALL STREET JOURNAL, MICROPAL, INC., MORNINGSTAR, STANGER'S, BARRON'S, etc.,
as well as  LIPPER,  may also be  utilized.  The  Fund's  promotional  and sales
literature may make reference to the Fund's "beta".  Beta is a reflection of the
market  related  risk of the Fund by showing how  responsive  the Fund is to the
market.

The performance of the Fund is not fixed or guaranteed.  Performance  quotations
should not be considered to be  representations  of  performance of the Fund for
any period in the  future.  The  performance  of the Fund is a function  of many
factors  including  its  earnings,  expenses and number of  outstanding  shares.
Fluctuating  market  conditions;  purchases,  sales and  maturities of portfolio
securities;  sales and redemptions of shares of beneficial interest; and changes
in  operating  expenses  are all examples of items that can increase or decrease
the Fund's performance.

Brokerage Allocation

Decisions  concerning  the  purchase and sale of  portfolio  securities  and the
allocation  of  brokerage  commissions  are  made  by the  Adviser  pursuant  to
recommendations made by an investment  committee of the Adviser,  which consists
of officers and  directors of the Adviser and  affiliates,  and Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner  which,  in the opinion of the  Adviser,  will offer the best
price and market for the  execution  of each such  transaction.  Purchases  from
underwriters  of portfolio  securities  may include a commission or  commissions
paid by the issuer  and  transactions  with  dealers  serving  as market  makers
reflect a "spread." Debt securities are generally  traded on a net basis through
dealers  acting  for their own  account as  principals  and not as  brokers;  no
brokerage commissions are payable on these transactions.

The Fund's  primary  policy is to execute all  purchases  and sales of portfolio
instruments  at the  most  favorable  prices  consistent  with  best  execution,
considering all of the costs of the transaction including brokerage commissions.
This policy governs the selection of brokers and dealers and the market in which
a transaction is executed.  Consistent with the foregoing  primary  policy,  the
Rules of Fair Practice of the National  Association of Securities Dealers,  Inc.
and such other policies as the Trustees may determine,  the Adviser may consider
sales of shares of the Fund as a factor in the  selection of  broker-dealers  to
execute the Fund's portfolio transactions.

To the extent consistent with the foregoing, the Fund will be governed in the
selection of brokers and dealers, and the negotiation of brokerage commission
rates and dealer spreads, by the reliability and quality of the services,
including primarily the availability and value of research information and to a
lesser extent statistical assistance furnished to the Adviser of the Fund, and
their value and expected contribution to the performance of the Fund. It is not
possible to place a dollar value on information and services to be received from
brokers and dealers, since it is only supplementary to the research efforts of
the Adviser. The receipt of research information is not expected to reduce
significantly the expenses of the Adviser. The research information and
statistical assistance furnished by brokers and dealers may benefit the Life

                                       51
<PAGE>


Company or other advisory clients of the Adviser, and, conversely, brokerage
commissions and spreads paid by other advisory clients of the Adviser may result
in research information and statistical assistance beneficial to the Fund. The
Fund will make no commitment to allocate portfolio transactions upon any
prescribed basis. While the Adviser's officers will be primarily responsible for
the allocation of the Fund's brokerage business, the policies in this regard
must be consistent with the foregoing and will at all times be subject to review
by the Trustees. For the fiscal years ended August 31, 1997, 1998 and 1999, the
Fund paid negotiated brokerage commissions in the amount of $5,172, $2,413 and
$910, respectively.

As permitted by Section 28(e) of the Securities  Exchange Act of 1934, the Funds
may pay to a broker which provides  brokerage and research  services to the Fund
an amount of disclosed  commission  in excess of the  commission  which  another
broker would have  charged for  effecting  that  transaction.  This  practice is
subject  to a good  faith  determination  by the  Trustees  that  the  price  is
reasonable  in light of the services  provided and to policies that the Trustees
may adopt from time to time.  During the fiscal year ended August 31, 1999,  the
Fund  did not pay  commissions  as  compensation  to any  brokers  for  research
services  such as industry,  economic  and company  reviews and  evaluations  of
securities.

The  Adviser's  indirect  parent,  the  Life  Company,   is  the  indirect  sole
shareholder of Signator Investors, Inc., a broker-dealer (until January 1, 1999,
John Hancock Distributors, Inc.) ("Signator" or Affiliated Broker"). Pursuant to
procedures  determined by the Trustees and  consistent  with the above policy of
obtaining best net results, the Fund may execute portfolio  transactions with or
through the Affiliated  Broker.  During the fiscal years ending August 31, 1997,
1998 and 1999,  the Fund did not execute  any  portfolio  transactions  with the
Affiliated Broker.

Signator  may act as  broker  for the Fund on  exchange  transactions,  subject,
however,  to the general  policy of the Fund set forth above and the  procedures
adopted by the Trustees pursuant to the Investment Company Act. Commissions paid
to an  Affiliated  Broker  must be at least as  favorable  as  those  which  the
Trustees believe to be contemporaneously  charged by other brokers in connection
with comparable  transactions  involving  similar  securities being purchased or
sold. A transaction  would not be placed with an  Affiliated  Broker if the Fund
would have to pay a commission rate less favorable than the Affiliated  Broker's
contemporaneous  charges for comparable transactions for its other most favored,
but unaffiliated customers,  except for accounts for which the Affiliated Broker
acts as clearing  broker for another  brokerage  firm,  and any customers of the
Affiliated  Broker not comparable to the Fund as determined by a majority of the
Trustees who are not interested  persons (as defined in the  Investment  Company
Act) of the Fund,  the Adviser or the  Affiliated  Broker.  Because the Adviser,
which is affiliated with the Affiliated Broker, has, as an investment adviser to
the Funds,  the  obligation to provide  investment  management  services,  which
includes elements of research and related investment  skills,  such research and
related  skills  will  not be  used by the  Affiliated  Broker  as a  basis  for
negotiating commissions at a rate higher than that determined in accordance with
the above criteria.

Other investment advisory clients advised by the Adviser may also invest in the
same securities as the Fund. When these clients buy or sell the same securities
at substantially the same time, the Adviser may average the transaction as to
price and allocate the amount of available investments in a manner which the
Adviser believes to be equitable to each client, including the Fund. Because of
this, client accounts in a particular style may sometimes not sell or acquire
securities as quickly or at the same prices as they might if each were managed
and traded individually.

<PAGE>


For  purchases  of equity  securities,  when a complete  order is not filled,  a
partial  allocation  will be made to each  account  pro rata  based on the order
size.  For high demand issues (for example,  initial public  offerings),  shares
will be  allocated  pro rata by account  size as well as on the basis of account
objective,  account  size ( a small  account's  allocation  may be  increased to
provide it with a meaningful  position),  and the account's other  holdings.  In
addition,  an account's  allocation may be increased if that account's portfolio
manager was  responsible  for generating  the  investment  idea or the portfolio
manager  intends to buy more shares in the  secondary  market.  For fixed income
accounts, generally securities will be allocated when appropriate among accounts
based on account size, except if the accounts have different objectives or if an
account is too small to get a  meaningful  allocation.  For new  issues,  when a
complete order is not filled, a partial  allocation will be made to each account
pro rata based on the order size.  However, if a partial allocation is too small
to be  meaningful,  it may be  reallocated  based  on such  factors  as  account
objectives,  duration  benchmarks  and  credit  and  sector  exposure.  In  some
instances,  this  investment  procedure may  adversely  affect the price paid or
received by the Fund or the size of the position obtainable for it. On the other
hand, to the extent  permitted by law, the adviser may aggregate the  securities
to be sold or  purchased  for the Fund with  those to be sold or  purchased  for
other clients managed by it in order to obtain best execution.

 Transfer Agent Services

John Hancock Signature  Services,  Inc., 1 John Hancock Way, Suite 1000, Boston,
MA 02217-1000,  a wholly-owned  indirect  subsidiary of the Life Company, is the
transfer  and  dividend  paying  agent  for the Fund.  The Fund  pays  Signature
Services an annual fee of $20.00 for each Class A  shareholder  account,  $22.50
for each Class B  shareholder  account  and $21.50 for each Class C  shareholder
account.  The Fund also pays certain  out-of-pocket  expenses and these expenses
are  aggregated and charged to the Fund on the basis of their relative net asset
values.

Custody Of Portfolio

Portfolio  securities  of the Fund are held  pursuant to a  custodian  agreement
between the Fund and  Investors  Bank & Trust  Company,  200  Clarendon  Street,
Boston, MA 02116. Under the custodian agreement,  Investors Bank & Trust Company
performs custody, portfolio and fund accounting services.

Independent ACCOUNTANTs

The independent accountants of the Fund are PricewaterhouseCoopers LLP, 160
Federal Street, Boston, Massachusetts 02110. PricewaterhouseCoopers LLP audits
and renders an opinion on the Fund's annual financial statements and reviews the
Fund's annual Federal income tax return.

APPENDIX A

MORE ABOUT RISK

A fund's risk profile is largely  defined by the fund's  primary  securities and
investment  practices.  You may find the most concise  description of the fund's
risk profile in the prospectus.

A fund is permitted to utilize -- within limits  established  by the trustees --
certain other  securities  and  investment  practices that have higher risks and
opportunities  associated  with them. To the extent that the Fund utilizes these
securities  or  practices,  its  overall  performance  may be  affected,  either
positively  or  negatively.  On the  following  pages are brief  definitions  of
certain  associated  risks with them with  examples  of related  securities  and
investment  practices included in brackets.  See the "Investment  Objectives and
Policies" and "Investment Restrictions" sections of this Statement of Additional
Information  for a  description  of this Fund's  investment  policies.  The Fund
follows certain policies that may reduce these risks.

As with any mutual fund, there is no guarantee that the Fund will earn income or
show a positive return over any period of time -- days, months or years.

TYPES OF INVESTMENT RISK

Correlation risk The risk that changes in the value of a hedging instrument will
not match those of the asset being hedged  (hedging is the use of one investment
to offset the effects of another investment).  Incomplete correlation can result
in unanticipated risks. (e.g., futures and related options; securities and index
options, swaps, caps, floors, collars).

Credit risk The risk that the issuer of a  security,  or the  counterparty  to a
contract,  will  default  or  otherwise  become  unable  to  honor  a  financial
obligation.  Common to all debt securities.(e.g.  borrowing;  reverse repurchase
agreements, repurchase agreements, financial futures and options; securities and
index options, securities lending, non-investment grade debt securities, private
activity bonds, participation interests and structured securities,  swaps, caps,
floors, collars).

Information risk The risk that key information about a security or market is
inaccurate or unavailable. Common to all municipal securities. (e.g.
non-investment grade debt securities, private activity bonds and participation
interests).

Interest rate risk The risk of market losses attributable to changes in interest
rates. With fixed-rate  securities,  a rise in interest rates typically causes a
fall in values,  while a fall in rates typically causes a rise in values.  (e.g.
financial  futures and options;  securities  and index  options,  non-investment
grade  debt  securities,   private  activity  bonds,   participation  interests,
structured securities and swaps, caps, floors and collars).

Leverage risk  Associated  with securities or practices (such as borrowing) that
multiply  small index or market  movements  into large  changes in value.  (e.g.
borrowing;  reverse repurchase  agreements,  when-issued  securities and forward
commitments).

o    Hedged  When a  derivative  (a  security  whose  value is based on  another
     security or index) is used as a hedge against an opposite position that the
     fund  also  holds,   any  loss  generated  by  the  derivative   should  be
     substantially  offset by gains on the hedged  investment,  and vice  versa.
     While  hedging  can  reduce  or  eliminate  losses,  it can also  reduce or
     eliminate gains.

                                      A-1
<PAGE>


o    Speculative  To the extent that a  derivative  is not used as a hedge,  the
     fund is directly exposed to the risks of that  derivative.  Gains or losses
     from  speculative  positions in a derivative may be  substantially  greater
     than the derivative's original cost.

o    Liquidity  risk  The risk  that  certain  securities  may be  difficult  or
     impossible  to sell at the time and the price that the seller  would  like.
     The seller may have to lower the price, sell other securities  instead,  or
     forego an investment opportunity, any of which could have a negative effect
     on fund management or  performance.  (e.g.  financial  futures and options;
     securities  and  index  options,   non-investment-grade   debt  securities,
     restricted and illiquid securities,  participation interests,  swaps, caps,
     floors, collars , structured securities).

Management risk The risk that a strategy used by a fund's management may fail to
produce the intended result. Common to all mutual funds.

Market risk The risk that the market  value of a security  may move up and down,
sometimes rapidly and unpredictably.  These fluctuations may cause a security to
be worth less than the price  originally  paid for it, or less than it was worth
at an earlier time. Market risk may affect a single issuer, industry,  sector of
the  economy  or the  market as a whole.  Common to all stocks and bonds and the
mutual  funds  that  invest  in  them.  (e.g.  financial  futures  and  options;
securities and index options,  short-term  trading,  when-issued  securities and
forward  commitments,   non-investment-grade  debt  securities,  restricted  and
illiquid securities, structured securities).

Natural event risk The risk of losses attributable to natural disasters, such as
earthquakes and similar events. (e.g. private activity bonds).

Opportunity  risk The risk of missing out on an investment  opportunity  because
the assets  necessary to take  advantage of it are tied up in less  advantageous
investments.  (e.g. financial futures and options; securities and index options,
when-issued securities and forward commitments).

Political risk The risk of losses attributable to government or political
actions of any sort. (e.g. private activity bonds).

Valuation  risk The risk that a fund has valued  certain of its  securities at a
higher  price  than  it  can  sell  them  for.(e.g.   non-investment-grade  debt
securities,   Restricted  and  illiquid  securities,   participation  interests,
structured securities, swaps, caps, floors, collars).

APPENDIX B

Ratings

Moody's describes its ratings for Tax-Exempt Bonds as follows:

Bonds.  "Bonds which are rated 'Aaa' are judged to be of the best quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
'gilt edge.' Interest  payments are protected by a large or by an  exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

"Bonds which are rated 'Aa' are judged to be of high  quality by all  standards.
Together with the 'Aaa' group they  comprise  what are  generally  known as high
grade  bonds.  They are rated  lower  than the best  bonds  because  margins  of
protection  may  not be as  large  as in  'Aaa'  securities  or  fluctuation  of
protective  elements may be of grater  amplitude or there may be other  elements
present  which make the long term risks  appear  somewhat  larger  than in 'Aaa'
securities.

"Bonds which are rated 'A' possess many favorable investment  attributes and are
to be considered as upper medium grade  obligations.  Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

"Bonds which are rated 'Baa' are considered as medium grade  obligations,  i.e.,
they are neither  highly  protected nor poorly  secured.  Interest  payments and
principal  security  appear  adequate  for the present  but  certain  protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding  investment  characteristics  and in
fact have speculative characteristics as well.

"Bonds  which are rated  'Ba' are  judged to have  speculative  elements;  their
future cannot be considered  as well assured.  Often the  protection of interest
and  principal  payments may be very  moderate and thereby not well  safeguarded
during  both  good and bad  times  over the  future.  Uncertainty  of  position,
characterizes bonds in this class.

"Bonds  which are rated 'B'  generally  lack  characteristics  of the  desirable
investment.  Assurance of interest and principal  payments or of  maintenance of
other terms of the contract over any long period of time may be small.

"Bonds which are rated 'Caa' are of poor standing. Such issues may be in default
or there may be  present  elements  of  danger  with  respect  to  principal  or
interest.

"Bonds which are rated 'Ca'  represent  obligations  which are  speculative in a
high degree. Such issues are often in default or have other marked shortcomings.

"Bonds which are rated 'C' are the lowest rated classes of bonds,  and issues so
rated can be regarded as having  extremely  poor prospects of ever obtaining any
real investment standing."

Where no  rating  has been  assigned  or where a rating  has been  suspended  or
withdrawn,  it may be for reasons unrelated to the quality of the issue.  Should
no  rating  be  assigned,  the  reason  may  be one  of  the  following:  (i) an
application  for rating was not received or  accepted;  (ii) the issue or issuer
belongs to a group of securities that are not rated as a matter of policy; (iii)
there is a lack of essential data pertaining to the issue or issuer; or (iv) the
issue was privately placed, in which case the rating is not published in Moody's
publications.

                                      B-1
<PAGE>


Suspension or withdrawal may occur if new and material  circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable  up-to-date  data to permit a  judgment  to be  formed;  if a bond is
called for redemption; or for other reasons.

Standard & Poor's describes its ratings for Tax-Exempt Bonds as follows:

"AAA. Debt rated 'AAA' has the highest rating by Standard & Poor's. Capacity to
pay interest and repay principal is extremely strong.

"AA. Debt rated 'AA' has a very strong capacity to pay interest and repay
principal and differs from the higher rated issues only in small degree.

"A. Debt rated 'A' has a strong  capacity to pay  interest  and repay  principal
although it is somewhat more  susceptible  to the adverse  effects of changes in
circumstances and economic conditions than debt in higher rated categories.

"BBB. Debt rated 'BBB' is regarded as having  adequate  capacity to pay interest
and  repay  principal.   Whereas  it  normally  exhibits   adequate   protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
debt in this category than in higher rated categories."

Debt rated "BB," "B," "CCC," or "CC" is regarded,  on balance,  as predominantly
speculative  with  respect to the  issuer's  capacity  to pay  interest  and pay
principal in accordance  with the terms of the  obligation.  "BB"  indicates the
lowest degree of speculation and "CC" the highest degree of  speculation.  While
such debt will likely have some quality and  protective  characteristics,  these
may be  outweighed  by large  uncertainties  or major risk  exposures to adverse
conditions.

Unrated.  This  indicates  that no  rating  has been  requested,  that  there is
insufficient  information  on which to base a rating,  or that Standard & Poor's
does not rate a particular type of obligation as a matter of policy.

Fitch describes its rating for Tax-Exempt Bonds as follows:

         AAA. Bonds considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonably foreseeable
events.

         AA. Bonds  considered  to be  investment  grade and of very high credit
quality.  The  obligor's  ability to pay  interest  and repay  principal is very
strong,  although not quite as strong as bonds rated "AAA".  Because bonds rated
in the  "AAA"  and the  'AA'  categories  are not  significantly  vulnerable  to
foreseeable future  developments,  short-term debt of these issuers is generally
rated 'F-1+'.

         A. Bonds  considered to be investment grade and of high credit quality.
The  obligor's  ability to pay interest and repay  principal is considered to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

         BBB. Bonds considered to be investment grade and of satisfactory credit
quality. The obligor's ability to pay interest and repay principal is considered
to be  adequate.  Adverse  changes in  economic  conditions  and  circumstances,
however,  are more likely to have adverse impact on these bonds,  and therefore,
impair timely payment.  The likelihood that the ratings of these bonds will fall
below investment grade is higher than for bonds with higher ratings.

                                      B-2
<PAGE>


         BB. Bonds are  considered  speculative.  The  obligor's  ability to pay
interest  and repay  principal  may be  affected  over time by adverse  economic
changes.  However,  business and financial  alternatives can be identified which
could assist the obligor in satisfying its debt service requirements.

Notes.  Ratings for state and municipal notes and other  short-term  obligations
will be designated  Moody's  Investment  Grade ("MIG").  This  distinction is in
recognition  of the  differences  between  short-term  credit risk and long-term
risk.  Factors  affecting  the  liquidity  of  the  borrower  are  uppermost  in
importance  in  short-term  borrowing,   while  various  factors  of  the  first
importance on bond risk are of lesser  importance in the short run. Symbols will
be used as follows:

"MIG-1 Notes bearing this  designation are of the best quality,  enjoying strong
protection  from  established  cash flows of funds for their  servicing  or from
established and broad-based access to the market for refinancing, or both.

"MIG-2  Notes  bearing  this  designation  are of high  quality  with margins of
protection ample although not so large as in the preceding group."

Commercial  Paper.  As  described  in the  Prospectus,  the Fund may  invest  in
commercial  paper which is rated A-1 or A-2 by Standard & Poor's,  P-1 or P-2 by
Moody's or F-1+ or f1 by Fitch.

Moody's  ratings for commercial  paper are opinions of the ability of issuers to
repay  punctually  promissory  obligations  not having an  original  maturity in
excess of nine months.  Moody's two highest  commercial paper rating  categories
are as follows:

"P-1 -- "Prime-1"  indicates the highest quality repayment capacity of the rated
issues.

"P-2 -- "Prime-2"  indicates that the issuer has a strong capacity for repayment
of short-term promissory obligations. Earnings trends and coverage ratios, while
sound,  will be more  subjective to variation.  Capitalization  characteristics,
while still  appropriate,  may be more  affected by external  conditions.  Ample
alternate liquidity is maintained."

Standard & Poor's  commercial  paper  ratings  are  current  assessments  of the
likelihood  of timely  payment of debts  having an original  maturity of no more
than 365 days.  Standard & Poor's two highest commercial paper rating categories
are as follows:

"A-1 -- This  designation  indicates that the degree of safety  regarding timely
payment is very strong.  Those issues determined to possess  overwhelming safety
characteristics will be denoted with a plus (+) sign designation.

"A-2 -- Capacity for timely payment on issues with this designation is strong.
However, the relative degree of safety is not as high as for issues designated
A-1."

Fitch's  short-term ratings apply to debt obligations that are payable on demand
or have original maturities of generally up to three years, including commercial
paper,  certificates  of deposit,  medium notes,  and  municipal and  investment
notes.

                                      B-3
<PAGE>


The  short-term  rating places greater  emphasis than a long-term  rating on the
existence of liquidity  necessary to meet the issuer's  obligations  in a timely
manner.

Fitch's short-term ratings are as follows:

F-1+ Exceptionally strong Credit Quality. Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

F-1 Very Strong Credit Quality. Issues assigned this rating reflect an assurance
of timely payment only slightly less in degree than issues rated "F-1+"

ORGANIZATION OF THE FUND

The Fund is a series of the Trust,  an open-end  investment  management  company
organized as a Massachusetts  business trust under the laws of The  Commonwealth
of  Massachusetts.  Prior to July 1, 1996, the New York Tax-Free Income Fund was
known as the New York Portfolio.


John Hancock Advisers, Inc. (the "Adviser") is the Fund's investment adviser.
The Adviser is an indirect wholly-owned subsidiary of John Hancock Life
Insurance Company (formerly John Hancock Mutual Life Insurance Company) (the
"Life Company"), a Massachusetts life insurance company chartered in 1862, with
national headquarters at John Hancock Place, Boston, Massachusetts. The Life
Company is wholly owned by John Hancock Financial Services, Inc., a Delaware
Corporation organized in February, 2000.


INVESTMENT OBJECTIVE AND POLICIES

The following  information  supplements the discussion of the Fund's  investment
objective and policies discussed in the Prospectus.  Appendix A contains further
information describing investment risks. The investment objective of the Fund is
not fundamental and may be changed by the Trustees without shareholder approval.
There is no assurance that the Fund will achieve its investment objective.

The Fund's objective is to provide investors with current income excludable from
gross income for Federal income tax purposes and exempt from the personal income
tax of New York State and New York City.  The Fund seeks to provide  the maximum
level of tax-exempt income that is consistent with preservation of capital.

Non-Diversification.  The Fund has registered as a "non-diversified"  investment
company, permitting the Adviser to invest more than 5% of the assets of the Fund
in the obligations of any one issuer.  Since a relatively high percentage of the
Fund's assets may be invested in the obligations of a limited number of issuers,
the  value  of Fund  shares  may be more  susceptible  to any  single  economic,
political  or  regulatory  event  than the  shares of a  diversified  investment
company.

Additional  Risks.  Securities  in which the Fund may invest are  subject to the
provisions of  bankruptcy,  insolvency  and other laws  affecting the rights and
remedies of creditors,  such as the Federal  Bankruptcy  Code, and laws, if any,
which  may be  enacted  by  Congress  or,  as the  case  may be,  the  New  York
legislature extending the time for payment of principal or interest, or both, or
imposing other constraints upon enforcement of such  obligations.  There is also
the possibility that, as a result of litigation or other  conditions,  the power
or ability of any one or more issuers to pay when due  principal of and interest
on their tax-exempt securities may be materially affected.

From time to time, proposals have been introduced before Congress which would
adversely affect the Federal income tax consequences of holding tax-exempt
securities. Federal tax legislation enacted primarily during the 1980's limits
the types and amounts of tax-exempt bonds issuable for certain purposes,
especially industrial development bonds and other types of "private activity"
bonds. Such limits may affect the future supply and yields of these types of
tax-exempt securities. Further proposals limiting the issuance of tax-exempt
securities may well be introduced in the future. If it appeared that the
availability of tax-exempt securities for investment by the Fund and the value
of the Fund's investments could be materially affected by such changes in law,
the Trustees would reevaluate the Fund's investment objective and policies and
consider changes in the structure of the Fund or its dissolution.

                                       2

All of the investments of the Fund will be made in:

         (1)      tax-exempt  securities which at the time of purchase are rated
                  BB or better by Standard & Poor's  Ratings Group  ("S&P"),  or
                  Fitch  Investors  Services,  Inc.  ("Fitch")  or Ba by Moody's
                  Investors Service, Inc. ("Moody's").  Alternatively, the bonds
                  may  be  unrated  but  considered  by  the  Adviser  to  be of
                  comparable  quality.  Not more than  one-third  of the  Fund's
                  total assets will be invested in tax-exempt  bonds rated lower
                  than A or determined to be of comparable quality.

         (2)      Notes of  issuers  having an issue of  outstanding  tax-exempt
                  securities  rated at least A by S&P,  Moody's or by Fitch,  or
                  notes which are  guaranteed  by the U.S.  Government  or rated
                  MIG-1  or  MIG-2  by  Moody's,  or  unrated  notes  which  are
                  determined to be of comparable quality by the Adviser.

         (3)      Obligations issued or guaranteed by the U.S.  Government,  its
                  agencies or  instrumentalities.  Some obligations issued by an
                  agency or  instrumentality  may be supported by the full faith
                  and credit of the U.S. Treasury, while others may be supported
                  only  by  the  credit  of the  particular  Federal  agency  or
                  instrumentality.

         (4)      Commercial  paper which is rated A-1 or A-2 by S&P, P-1 or P-2
                  by Moody's,  or at least F-1 by Fitch,  or which is not rated,
                  but is considered by the Adviser to be of comparable  quality;
                  obligations  of  banks  with $1  billion  of  assets  and cash
                  equivalents,   including  certificates  of  deposit,   bankers
                  acceptances and repurchase  agreements.  Ratings of A-2 or P-2
                  on  commercial  paper  indicate a strong  capacity  for timely
                  payment, although the relative degree of safety is not as high
                  as for  issuers  designated  A-1 or P-1.  Appendix  B contains
                  further information about ratings.

Tax-Exempt  Securities.  These  are debt  securities  issued  by or on behalf of
states,  territories  and  possessions  of the United States and the District of
Columbia and their political  subdivisions,  agencies or instrumentalities,  the
interest  on which is  excludable  from  gross  income  for  Federal  income tax
purposes,  without regard to whether the interest  income thereon is exempt from
the personal income tax of any state.

Tax-exempt  securities are issued to obtain funds for various  public  purposes,
including the construction of a wide range of public facilities such as bridges,
highways,  housing,  hospitals, mass transportation,  schools, streets and water
and sewer works.  Other public purposes for which  tax-exempt  securities may be
issued include the refunding of outstanding  obligations or obtaining  funds for
general operating expenses.

In addition,  certain types of "private  activity bonds" may be issued by public
authorities to finance privately  operated housing  facilities and certain local
facilities for water supply, gas, electricity, sewage or solid waste disposal or
student loans, or to obtain funds to lend to public or private  institutions for
the  construction  of  facilities  such as  educational,  hospital  and  housing
facilities.  Such private activity bonds are included within the term tax-exempt
securities  if the  interest  paid  thereon is  excluded  from gross  income for
Federal income tax purposes.

The interest  income on certain  private  activity  bonds  (including the Fund's
distributions to its shareholders  attributable to such interest) may be treated
as a tax  preference  item under the Federal  alternative  minimum tax. The Fund
will not include  tax-exempt  securities  generating this income for purposes of
measuring compliance with the 80% fundamental investment policy described in the
Prospectus.

                                       3
<PAGE>


Other types of private  activity  bonds,  the proceeds of which are used for the
construction,  equipment, repair or improvement of privately operated industrial
or commercial facilities, may also constitute tax-exempt securities, but current
Federal tax law places substantial limitations on the size of such issues.

The yields or returns on tax-exempt  securities  depend on a variety of factors,
including  general money market  conditions,  effective  marginal tax rates, the
financial  condition of the issuer,  general  conditions of the tax-exempt  bond
market,  the size of a particular  offering,  the maturity of the obligation and
the  rating  (if any) of the  issue.  The  ratings  of  Moody's  , Fitch and S&P
represent  their  opinions  as to the quality of various  tax-exempt  securities
which they undertake to rate. It should be emphasized, however, that ratings are
not absolute standards of quality. Consequently,  tax-exempt securities with the
same maturity and interest rate with different  ratings may have the same yield.
Yield  disparities may occur for reasons not directly  related to the investment
quality of particular  issues or the general  movement of interest rates, due to
such  factors  as changes in the  overall  demand or supply of various  types of
tax-exempt securities or changes in the investment objectives of investors.

The market value of debt securities which carry no equity participation  usually
reflects yields  generally  available on securities of similar quality and type.
When such yields decline,  the market value of a portfolio  already  invested at
higher yields can be expected to rise if such  securities are protected  against
early call. In general,  in selecting  securities,  the portfolio manager of the
Fund intends to seek protection against early call. Similarly,  when such yields
increase,  the market value of a portfolio  already invested at lower yields can
be  expected to decline.  The Fund may invest in debt  securities  which sell at
substantial  discounts  from par.  These  securities are low coupon bonds which,
during periods of high interest rates,  because of their lower  acquisition cost
tend to sell on a yield basis approximating current interest rates.

Municipal  Bonds.  Municipal  bonds  generally are  classified as either general
obligation  bonds or revenue bonds.  General  obligation bonds are backed by the
credit of an  issuer  having  taxing  power and are  payable  from the  issuer's
general unrestricted  revenues.  Their payment may depend on an appropriation of
the issuer's legislative body. Revenue bonds, by contrast, are payable only from
the revenues derived from a particular  project,  facility or a specific revenue
source.  They are not generally  payable from the  unrestricted  revenues of the
issuer.

"Moral  Obligation"  Bonds.  The Fund  currently  does not  intend  to invest in
so-called  "moral  obligation"  bonds,  unless the credit of the issuer  itself,
without  regard  to  the  "moral  obligation,"  meets  the  investment  criteria
established  for  investments  by  the  Fund.  With  "moral  obligation"  bonds,
repayment is backed by a moral commitment of an entity other than the issuer.

Tax-Exempt Notes. Tax-exempt notes generally are used to provide for short-term
capital needs and generally have maturities of one year or less. Tax-exempt
notes include:

Project Notes.  Project notes are backed by an agreement between a local issuing
agency and the Federal  Department of Housing and Urban Development  ("HUD") and
carry a United States Government guarantee.  These notes provide financing for a
wide range of financial  assistance  programs for  housing,  redevelopment,  and
related needs (such as low-income  housing programs and urban renewal programs).
Although they are the primary  obligations of the local public housing  agencies
or local urban renewal agencies,  the HUD agreement  provides for the additional
security of the full faith and credit of the United States  Government.  Payment
by the United States  pursuant to its full faith and credit  obligation does not
impair the tax-exempt character of the income from Project Notes.

Tax-Anticipation Notes. Tax anticipation notes are issued to finance working
capital needs of municipalities. Generally, they are issued in anticipation of
various tax revenues, such as income, sales, use and business taxes, and are
specifically payable from these particular future tax revenues.

                                       4
<PAGE>


Revenue Anticipation Notes. Revenue anticipation notes are issued in expectation
of receipt of  specific  types of  revenue,  other than  taxes,  such as federal
revenues available under Federal Revenue Sharing Programs.

Bond Anticipation  Notes. Bond anticipation  notes are issued to provide interim
financing  until  long-term bond financing can be arranged.  In most cases,  the
long-term bonds then provide the funds for the repayment of the Notes.

Construction   Loan  Notes.   Construction   loan  notes  are  sold  to  provide
construction financing.  Permanent financing,  the proceeds of which are applied
to the payment of construction loan notes, is sometimes provided by a commitment
by  the  Government   National  Mortgage   Association  to  purchase  the  loan,
accompanied  by a commitment  by the Federal  Housing  Administration  to insure
mortgage  advances  thereunder.  In  other  instances,  permanent  financing  is
provided by the commitments of banks to purchase the loan.

Commercial  Paper.  Issues of commercial paper typically  represent  short-term,
unsecured, negotiable promissory notes. These obligations are issued by agencies
of state and local  governments  to finance  seasonal  working  capital needs of
municipalities  or to provide interim  construction  financing and are paid from
general  revenues of  municipalities  or are refinanced  with long-term debt. In
most cases, tax- exempt commercial paper is backed by letters of credit, lending
agreements,  note  repurchase  agreements  or other credit  facility  agreements
offered by banks or other institutions.

Ratings as Investment Criteria.

Lower Rated High Yield "High Risk" Debt Obligations. The Fund may invest in high
yielding,  fixed income  securities  rated below Baa by Moody's or BBB by S&P or
Fitch or which are unrated but are considered by the Adviser to be of comparable
quality.  Ratings are based largely on the historical financial condition of the
issuer.  Consequently,  the rating  assigned to any  particular  security is not
necessarily a reflection of the issuer's current financial condition,  which may
be better or worse  than the rating  would  indicate.  Bonds  rated BB or Ba are
generally referred to as junk bonds. See "Appendix B" attached hereto.

The values of lower-rated securities and those which are unrated but which are
considered by the Adviser to be of comparable quality generally fluctuate more
than those of high-rated securities. These securities involve greater price
volatility and risk of loss of principal and income. In addition, the lower
rating reflects a greater possibility of an adverse change in financial
condition affecting the ability of the issuer to make payments of interest and
principal. The market price and liquidity of lower-rated securities generally
respond to short-term market developments to a greater extent than for higher
rated securities, because these developments are perceived to have a more direct
relationship to the issuer's ability to meet its ongoing debt obligations.
Although the Adviser seeks to minimize these risks through diversification,
investment analysis and attention to current developments in interest rates and
economic conditions, there can be no assurance that the Adviser will be
successful in limiting the Fund's exposure to the risks associated with lower
rated securities. Because the Fund invests in securities in the lower rated
categories, the achievement of the Fund's goals is more dependent on the
Adviser's ability than would be the case if the Fund was investing in securities
in the higher rated categories.

                                       5
<PAGE>


Ratings.  Ratings for Bonds issued by various  jurisdictions  are noted  herein.
Such ratings  reflect only the respective  views of such  organizations,  and an
explanation of the  significance of such ratings may be obtained from the rating
agency  furnishing  the same.  There is no assurance that a rating will continue
for any given  period of time or that a rating will not be revised or  withdrawn
entirely by any or all of such rating  agencies,  if, in its or their  judgment,
circumstances so warrant.  Any downward revision or withdrawal of a rating could
have an  adverse  effect on the  market  prices  of any of the  bonds  described
herein.

Restricted Securities.  The Fund may purchase securities that are not registered
("restricted  securities")  under  the  Securities  Act of  1933  ("1933  Act"),
including  commercial  paper  issued in reliance on Section 4(2) of the 1933 Act
and securities offered and sold to "qualified  institutional  buyers" under Rule
144A  under the 1933  Act.  The Fund  will not  invest  more than 15% of its net
assets  in  illiquid  investments.  If  the  Trustees  determine,  based  upon a
continuing review of the trading markets for specific Section 4(2) paper or Rule
144A securities, that they are liquid, they will not be subject to the 15% limit
on illiquid  securities.  The Trustees have adopted  guidelines and delegated to
the Adviser the daily  function of  determining  the monitoring and liquidity of
restricted securities.  The Trustees,  however, will retain sufficient oversight
and  be  ultimately  responsible  for  the  determinations.  The  Trustees  will
carefully monitor the Fund's  investments in these securities,  focusing on such
important  factors,  among others,  as valuation,  liquidity and availability of
information.  This  investment  practice could have the effect of increasing the
level of illiquidity in a the Fund if qualified  institutional buyers become for
a time uninterested in purchasing these restricted securities.

Participation Interests.  Participation interests may take the form of interests
in or of a lending syndicate.  The Fund's investments in participation interests
may be subject to its 15% net  assets  limitation  on  investments  in  illiquid
securities.  The fund may purchase only those participation interest that mature
in 60 days or less or, if  maturing  in more than 60 days,  that have a floating
rate that is automatically  adjusted at least once every 60 days.  Participation
interests in municipal  lease  obligations  will not be considered  illiquid for
purposes  of the Fund's 15%  limitation  on  illiquid  securities  provided  the
Adviser determines that there is a readily available market for such securities.

In reaching liquidity  decisions,  the Adviser will consider,  among others, the
following factors: (1) the frequency of trades and quotes for the security;  (2)
the number of dealers wishing to purchase or sell the security and the number of
other  potential  purchasers;  (3) dealer  undertakings  to make a market in the
security and (4) the nature of the  security  and the nature of the  marketplace
trades  (e.g.,  the time  needed  to  dispose  of the  security,  the  method of
soliciting  offers and the mechanics of the transfer.) With respect to municipal
lease  obligations,  the Adviser  also  considers:  (1) the  willingness  of the
municipality  to continue,  annually or  biannually,  to  appropriate  funds for
payment of the lease; (2) the general credit quality of the municipality and the
essentiality to the  municipality of the property  covered by the lease;  (3) an
analysis  of  factors  similar  to  that  performed  by  nationally   recognized
statistical rating organizations in evaluating the credit quality of a municipal
lease  obligation,  including  (i)  whether the lease can be  canceled;  (ii) if
applicable, what assurance there is that the assets represented by the lease can
be sold;  (iii) the strength of the lessee's  general  credit  (e.g.,  its debt,
administrative,  economic and financial  characteristics);  (iv) the  likelihood
that the  municipality  will  discontinue  appropriating  funding for the leased
property because the property is no longer deemed essential to the operations of
the municipality (e.g., the potential for an event of nonappropriation); and (v)
the legal  recourse  in the event of failure to  appropriate;  and (4) any other
factors unique to municipal lease obligations as determined by the Adviser.

Repurchase Agreements. The Fund may enter into repurchase agreements for the
purpose of realizing additional (taxable) income. In a repurchase agreement the
Fund buys a security for a relatively short period (usually not more than 7
days) subject to the obligation to sell it back to the issuer at a fixed time
and price plus accrued interest. The Fund will enter into repurchase agreements
only with member banks of the Federal Reserve System and with "primary dealers"
in U.S. Government securities. The Adviser will continuously monitor the
creditworthiness of the parties with whom the Fund enters into repurchase
agreements.

                                       6
<PAGE>


The Fund has  established a procedure  providing that the securities  serving as
collateral  for  each  repurchase  agreement  must be  delivered  to the  Fund's
custodian  either  physically or in book-entry form and that the collateral must
be marked to market  daily to ensure  that each  repurchase  agreement  is fully
collateralized  at all times.  In the event of  bankruptcy or other default by a
seller  of  a  repurchase  agreement,   the  Fund  could  experience  delays  in
liquidating the underlying  securities during the period in which the Fund seeks
to enforce its rights thereto, possible subnormal levels of income, a decline in
value of the  underlying  securities  or lack of access to  income  during  this
period, and the expense of enforcing its rights.

Reverse Repurchase  Agreements.  The Fund may also enter into reverse repurchase
agreements  which  involve the sale of U.S.  Government  securities  held in its
portfolio to a bank with an agreement that the Fund will buy back the securities
at a fixed  future  date at a fixed  price plus an agreed  amount of  "interest"
which may be reflected in the repurchase price.  Reverse  repurchase  agreements
are  considered  to be  borrowings by the Fund.  Reverse  repurchase  agreements
involve the risk that the market value of securities  purchased by the Fund with
proceeds  of the  transaction  may  decline  below the  repurchase  price of the
securities  sold by the Fund which it is obligated to repurchase.  The Fund will
also  continue to be subject to the risk of a decline in the market value of the
securities sold under the agreements  because it will reacquire those securities
upon effecting their repurchase. The Fund will not enter into reverse repurchase
agreements and other borrowings exceeding in the aggregate 33 1/3% of the market
value of its total assets.  To minimize  various risks  associated  with reverse
repurchase agreements,  the Fund will establish a separate account consisting of
highly  liquid,  marketable  securities  in an  amount  at  least  equal  to the
repurchase prices of these securities (plus accrued interest thereon) under such
agreements.  In addition, the Fund will not purchase additional securities while
all  borrowings  are  outstanding.  The Fund will enter into reverse  repurchase
agreements  only with federally  insured banks or savings and loan  associations
which are  approved  in advance as being  creditworthy  by the  Trustees.  Under
procedures   established   by  the  Trustees,   the  Adviser  will  monitor  the
creditworthiness of the banks involved.

Options on Securities  and Securities  Indices.  The Fund may purchase and write
(sell)  call and put  options  on any  securities  in which it may invest on any
securities  index based on securities in which it may invest.  These options may
be  listed  on  national  domestic   securities   exchanges  or  traded  in  the
over-the-counter  market.  The Fund may write  covered put and call  options and
purchase put and call options to enhance total return,  as a substitute  for the
purchase or sale of securities,  or to protect against  declines in the value of
portfolio  securities  and against  increases  in the cost of  securities  to be
acquired.

Writing Covered Options. A call option on securities written by the Fund
obligates the Fund to sell specified securities to the holder of the option at a
specified price if the option is exercised at any time before the expiration
date. A put option on securities written by the Fund obligates the Fund to
purchase specified securities from the option holder at a specified price if the
option is exercised at any time before the expiration date. Options on
securities indices are similar to options on securities, except that the
exercise of securities index options requires cash settlement payments and does
not involve the actual purchase or sale of securities. In addition, securities
index options are designed to reflect price fluctuations in a group of
securities or segment of the securities market rather than price fluctuations in
a single security. Writing covered call options may deprive the Fund of the
opportunity to profit from an increase in the market price of the securities in
its portfolio. Writing covered put options may deprive the Fund of the
opportunity to profit from a decrease in the market price of the securities to
be acquired for its portfolio.

                                       7
<PAGE>


All call and put options written by the Fund are covered.  A written call option
or put option may be covered by (i) maintaining  cash or liquid  securities in a
segregated  account with a value at least equal to the Fund's  obligation  under
the option,  (ii) entering into an offsetting  forward  commitment  and/or (iii)
purchasing  an  offsetting  option or any other option  which,  by virtue of its
exercise  price or  otherwise,  reduces  the Fund's net  exposure on its written
option  position.  A written call option on securities  is typically  covered by
maintaining  the  securities  that are  subject  to the  option in a  segregated
account.  The Fund may  cover  call  options  on a  securities  index by  owning
securities  whose  price  changes  are  expected  to be  similar to those of the
underlying index.

The Fund may  terminate  its  obligations  under an exchange  traded call or put
option by purchasing an option identical to the one it has written.  Obligations
under  over-the-counter  options  may be  terminated  only by  entering  into an
offsetting  transaction with the counterparty to such option. Such purchases are
referred to as "closing purchase transactions."

Purchasing   Options.   The  Fund  would  normally   purchase  call  options  in
anticipation  of an  increase,  or put  options  in  anticipation  of a decrease
("protective  puts") in the market value of  securities  of the type in which it
may  invest.  The Fund may also  sell  call  and put  options  to close  out its
purchased options.

The purchase of a call option would  entitle the Fund, in return for the premium
paid, to purchase  specified  securities at a specified  price during the option
period.  The Fund  would  ordinarily  realize a gain on the  purchase  of a call
option if, during the option  period,  the value of such  securities or currency
exceeded the sum of the exercise price, the premium paid and transaction  costs;
otherwise the Fund would realize either no gain or a loss on the purchase of the
call option.

The purchase of a put option would entitle the Fund, in exchange for the premium
paid,  to sell  specified  securities  at a  specified  price  during the option
period. The purchase of protective puts is designed to offset or hedge against a
decline in the market value of the Fund's portfolio securities.  Put options may
also be purchased by the Fund for the purpose of affirmatively benefiting from a
decline  in the  price of  securities  which it does  not  own.  The Fund  would
ordinarily  realize  a gain if,  during  the  option  period,  the  value of the
underlying  securities  decreased below the exercise price sufficiently to cover
the premium and  transaction  costs;  otherwise the Fund would realize either no
gain or a loss on the  purchase  of the put  option.  Gains  and  losses  on the
purchase of put options may be offset by countervailing  changes in the value of
the Fund's portfolio securities.  Under certain circumstances,  the Fund may not
be treated as the tax owner of a security if the Fund has purchased a put option
on the same security.  If this  occurred,  the interest on the security would be
taxable.

The Fund's options  transactions  will be subject to limitations  established by
each of the exchanges, boards of trade or other trading facilities on which such
options are traded.  These  limitations  govern the maximum number of options in
each class which may be written or  purchased  by a single  investor or group of
investors  acting in concert,  regardless  of whether the options are written or
purchased on the same or different  exchanges,  boards of trade or other trading
facilities or are held or written in one or more accounts or through one or more
brokers. Thus, the number of options which the Fund may write or purchase may be
affected by options written or purchased by other investment advisory clients of
the Adviser. An exchange, board of trade or other trading facility may order the
liquidation  of  positions  found to be in  excess of these  limits,  and it may
impose certain other sanctions.

Risks Associated with Options Transactions. There is no assurance that a liquid
secondary market on an options exchange will exist for any particular
exchange-traded option or at any particular time. If the Fund is unable to
effect a closing purchase transaction with respect to covered options it has
written, the Fund will not be able to sell the underlying securities or dispose
of assets held in a segregated account until the options expire or are
exercised. Similarly, if the Fund is unable to effect a closing sale transaction
with respect to options it has purchased, it would have to exercise the options
in order to realize any profit and will incur transaction costs upon the
purchase or sale of underlying securities.

                                       8
<PAGE>


Reasons for the absence of a liquid  secondary market on an exchange include the
following:  (i) there may be insufficient  trading  interest in certain options;
(ii)  restrictions  may be imposed by an  exchange  on opening  transactions  or
closing  transactions  or  both;  (iii)  trading  halts,  suspensions  or  other
restrictions  may be imposed  with  respect to  particular  classes or series of
options;   (iv)  unusual  or  unforeseen   circumstances  may  interrupt  normal
operations  on an  exchange;  (v) the  facilities  of an exchange or the Options
Clearing  Corporation may not at all times be adequate to handle current trading
volume;  or (vi) one or more  exchanges  could,  for economic or other  reasons,
decide or be compelled at some future date to discontinue the trading of options
(or a particular class or series of options). If trading were discontinued,  the
secondary  market on that exchange (or in that class or series of options) would
cease to exist.  However,  outstanding  options on that  exchange  that had been
issued  by the  Options  Clearing  Corporation  as a result  of  trades  on that
exchange would continue to be exercisable in accordance with their terms.

The Fund's  ability to terminate  over-the-counter  options is more limited than
with  exchange-traded  options  and may  involve  the risk  that  broker-dealers
participating  in such  transactions  will not fulfill  their  obligations.  The
Adviser  will  determine  the  liquidity  of  each  over-the-counter  option  in
accordance with guidelines adopted by the Trustees.

The  writing  and  purchase of options is a highly  specialized  activity  which
involves  investment  techniques and risks different from those  associated with
ordinary  portfolio  securities  transactions.  The  successful  use of  options
depends in part on the Adviser's  ability to predict  future price  fluctuations
and, for hedging transactions, the degree of correlation between the options and
securities markets.

Futures  Contracts and Options on Futures  Contracts.  To seek to increase total
return or hedge against  changes in interest  rates and securities  prices,  the
Fund may purchase and sell various kinds of futures contracts,  and purchase and
write call and put options on these futures  contracts.  The Fund may also enter
into  closing  purchase  and  sale  transactions  with  respect  to any of these
contracts and options. The futures contracts may be based on various securities,
securities indices, and any other financial instruments and indices. All futures
contracts  entered  into by the Fund are traded on U.S.  exchanges  or boards of
trade that are licensed,  regulated or approved by the Commodity Futures Trading
Commission ("CFTC").

Futures Contracts. A futures contract may generally be described as an agreement
between  two parties to buy and sell  particular  financial  instruments  for an
agreed price during a designated  month (or to deliver the final cash settlement
price,  in the case of a contract  relating to an index or otherwise not calling
for physical delivery at the end of trading in the contract).

Positions taken in the futures markets are not normally held to maturity but are
instead liquidated through offsetting  transactions which may result in a profit
or a loss.  While futures  contracts on securities will usually be liquidated in
this manner,  the Fund may instead  make,  or take,  delivery of the  underlying
securities  whenever it appears  economically  advantageous to do so. A clearing
corporation  associated with the exchange on which futures  contracts are traded
guarantees  that,  if still open,  the sale or purchase will be performed on the
settlement date.

Hedging and Other Strategies with Future Contracts. Hedging is an attempt to
establish with more certainty than would otherwise be possible the effective
price or rate of return on portfolio securities or securities that the Fund
proposes to acquire. When securities prices are falling, the Fund can seek to
offset a decline in the value of its current portfolio securities through the
sale of futures contracts. When securities prices are rising, the Fund, through
the purchase of futures contracts, can attempt to secure better rates or prices
than might later be available in the market when it effects anticipated
purchases.

                                       9

The Fund may,  for  example,  take a "short"  position in the futures  market by
selling futures contracts in an attempt to hedge against an anticipated  decline
in market prices that would adversely  affect the value of the Fund's  portfolio
securities. Such futures contracts may include contracts for the future delivery
of securities  held by the Fund or securities  with  characteristics  similar to
those of the Fund's portfolio securities.

If, in the opinion of the Adviser,  there is a sufficient  degree of correlation
between price trends for the Fund's portfolio  securities and futures  contracts
based on other financial  instruments,  securities indices or other indices, the
Fund may also enter into such futures contracts as part of its hedging strategy.
Although under some  circumstances  prices of securities in the Fund's portfolio
may be more or less volatile than prices of such futures contracts,  the Adviser
will  attempt to  estimate  the extent of this  volatility  difference  based on
historical patterns and compensate for any differential by having the Fund enter
into a greater or lesser number of futures contracts or by attempting to achieve
only a partial  hedge  against  price  changes  affecting  the Fund's  portfolio
securities. When a short hedging position is successful, any depreciation in the
value of portfolio  securities will be  substantially  offset by appreciation in
the  value  of the  futures  position.  On the  other  hand,  any  unanticipated
appreciation  in  the  value  of  the  Fund's  portfolio   securities  would  be
substantially offset by a decline in the value of the futures position.

On other  occasions,  the Fund may take a "long" position by purchasing  futures
contracts.  This  would be done,  for  example,  when the Fund  anticipates  the
subsequent purchase of particular securities when it has the necessary cash, but
expects the prices then available in the applicable  market to be less favorable
than prices that are currently  available.  The Fund may also  purchase  futures
contracts as a substitute for transactions in securities to alter the investment
characteristics of portfolio securities or to gain or increase its exposure to a
particular securities market.

Options on Futures Contracts. The Fund may purchase and write options on futures
for the same purposes as its transactions in futures contracts.  The purchase of
put and call options on futures  contracts will give the Fund the right (but not
the obligation) for a specified price to sell or to purchase,  respectively, the
underlying  futures  contract  at any time  during  the  option  period.  As the
purchaser  of an option on a futures  contract,  the Fund obtains the benefit of
the futures position if prices move in a favorable direction but limits its risk
of loss in the event of an unfavorable price movement to the loss of the premium
and transaction costs.

The writing of a call option on a futures contract generates a premium which may
partially offset a decline in the value of the Fund's assets.  By writing a call
option, the Fund becomes  obligated,  in exchange for the premium (upon exercise
of the option) to sell a futures contract if the option is exercised,  which may
have a value higher than the exercise  price.  Conversely,  the writing of a put
option on a futures  contract  generates a premium which may partially offset an
increase in the price of securities that the Fund intends to purchase.  However,
the Fund becomes  obligated  (upon exercise of the option) to purchase a futures
contract  if the  option is  exercised,  which may have a value  lower  than the
exercise  price.  The loss incurred by the Fund in writing options on futures is
potentially unlimited and may exceed the amount of the premium received.

The holder or writer of an option on a futures contract may terminate its
position by selling or purchasing an offsetting option of the same series. There
is no guarantee that such closing transactions can be effected. The Fund's
ability to establish and close out positions on such options will be subject to
the development and maintenance of a liquid market.

                                       10

Other  Considerations.  The Fund will  engage in  futures  and  related  options
transactions  either for bona fide hedging purposes or to seek to increase total
return as  permitted by the CFTC.  To the extent that the Fund is using  futures
and related  options for hedging  purposes,  futures  contracts  will be sold to
protect  against a  decline  in the  price of  securities  that the Fund owns or
futures  contracts  will be purchased to protect the Fund against an increase in
the price of securities it intends to purchase. The Fund will determine that the
price  fluctuations  in the futures  contracts  and options on futures  used for
hedging purposes are substantially  related to price  fluctuations in securities
held by the Fund or securities or instruments  which it expects to purchase.  As
evidence  of its hedging  intent,  the Fund  expects  that on 75% or more of the
occasions on which it takes a long  futures or option  position  (involving  the
purchase of futures contracts),  the Fund will have purchased, or will be in the
process of  purchasing,  equivalent  amounts of related  securities  in the cash
market at the time when the futures or option  position is closed out.  However,
in particular cases, when it is economically advantageous for the Fund to do so,
a long futures  position may be terminated  or an option may expire  without the
corresponding purchase of securities or other assets.

To the  extent  that the Fund  engages  in  nonhedging  transactions  in futures
contracts  and options on futures,  the  aggregate  initial  margin and premiums
required to establish these  nonhedging  positions will not exceed 5% of the net
asset  value of the Fund's  portfolio,  after  taking  into  account  unrealized
profits and losses on any such  positions and excluding the amount by which such
options were in-the-money at the time of purchase.

Transactions  in futures  contracts  and  options on futures  involve  brokerage
costs,  require  margin  deposits  and,  in the case of  contracts  and  options
obligating  the Fund to purchase  securities,  require  the Fund to  establish a
segregated account consisting of cash or liquid securities in an amount equal to
the underlying value of such contracts and options.

While  transactions  in futures  contracts  and  options  on futures  may reduce
certain risks,  these  transactions  themselves  entail certain other risks. For
example, unanticipated changes in interest rates or securities prices may result
in a poorer overall performance for the Fund than if it had not entered into any
futures contracts or options transactions.

Perfect correlation between the Fund's futures positions and portfolio positions
will be impossible to achieve. In the event of an imperfect  correlation between
a futures  position and a portfolio  position which is intended to be protected,
the desired  protection  may not be obtained and the Fund may be exposed to risk
of loss.

Some futures  contracts or options on futures may become  illiquid under adverse
market conditions. In addition, during periods of market volatility, a commodity
exchange may suspend or limit trading in a futures  contract or related  option,
which may make the  instrument  temporarily  illiquid  and  difficult  to price.
Commodity exchanges may also establish daily limits on the amount that the price
of a  futures  contract  or  related  option  can vary from the  previous  day's
settlement  price.  Once the daily limit is reached,  no trades may be made that
day at a price  beyond the limit.  This may  prevent  the Fund from  closing out
positions and limiting its losses.

Structured or Hybrid Notes. The Fund may invest in "structured" or "hybrid"
notes. The distinguishing feature of a structured or hybrid note is that the
amount of interest and/or principal payable on the note is based on the
performance of a benchmark asset or market other than fixed income securities or
interest rates. Examples of these benchmarks include stock prices, currency
exchange rates and physical commodity prices. Investing in a structured note
allows the Fund to gain exposure to the benchmark market while fixing the
maximum loss that the Fund may experience in the event that market does not
perform as expected. Depending on the terms of the note, the Fund may forego all
or part of the interest and principal that would be payable on a comparable
conventional note; the Fund's loss cannot exceed this foregone interest and/or
principal. An investment in structured or hybrid notes involves risks similar to
those associated with a direct investment in the benchmark asset.

                                       11
<PAGE>


Indexed  Securities.  The Fund  may  invest  in  indexed  securities,  including
floating rate  securities  that are subject to a maximum  interest rate ("capped
floaters") and leveraged inverse floating rate securities  ("inverse  floaters")
(up to 10% of the Fund's total assets). The interest rate or, in some cases, the
principal  payable at the maturity of an indexed security may change  positively
or inversely in a relation to one or more interest rates,  financial indices, or
other financial  indicators  ("reference  prices").  An indexed  security may be
leveraged to the extent that the magnitude of any change in the interest rate or
principal  payable on an  indexed  security  is a multiple  of the change in the
reference price.  Thus,  indexed  securities may decline in value due to adverse
market charges in interest rates or other reference prices.

Risk  Associated With Specific Types of Derivative  Debt  Securities.  Different
types of derivative  debt  securities are subject to different  combinations  of
prepayment,  extension and/or interest rate risk. The risk of early  prepayments
is the primary risk associated with interest only debt securities ("IOs"), super
floaters and other leveraged floating rate instruments. In some instances, early
prepayments  may result in a  complete  loss of  investment  in certain of these
securities.  The primary risks  associated  with certain other  derivative  debt
securities are the potential  extension of average life and/or  depreciation due
to rising interest rates.

Derivative debt securities include floating rate securities based on the Cost of
Funds Index ("COFI  floaters"),  other "lagging rate" floating rate  securities,
floating rate  securities  that are subject to a maximum  interest rate ("capped
floaters"),  leveraged  inverse floating rate securities  ("inverse  floaters"),
principal only debt securities  ("POs") and certain residual or support branches
of index amortizing notes.  Index amortizing notes are subject to extension risk
resulting from the issuer's failure to exercise its option to call or redeem the
notes  before  their  stated  maturity  date.  Leveraged  inverse IOs present an
especially intense combination of prepayment, extension and interest rate risks.

Other types of floating rate  derivative  debt  securities  present more complex
types of interest  rate risks.  For example,  range  floaters are subject to the
risk that the  coupon  will be  reduced to below  market  rates if a  designated
interest rate floats outside of a specified  interest rate band or collar.  Dual
index or yield curve  floaters  are subject to  depreciation  in the event of an
unfavorable change in the spread between two designated interest rates. X- reset
floaters  have a coupon that  remains  fixed for more than one  accrual  period.
Thus, the type of risk involved in these securities depends on the terms of each
individual X-reset floater.

Forward Commitment and When-Issued Securities.  The Fund may purchase securities
on a when-issued or forward commitment basis. "When-issued" refers to securities
whose terms are available and for which a market exists, but which have not been
issued.  The Fund will  engage  in  when-issued  transactions  with  respect  to
securities  purchased for its portfolio in order to obtain what is considered to
be an  advantageous  price  and  yield  at  the  time  of the  transaction.  For
when-issued  transactions,  no payment is made until  delivery  is due,  often a
month or more after the purchase. In a forward commitment transaction,  the Fund
contracts  to  purchase  securities  for a fixed  price at a future  date beyond
customary settlement time.

When the Fund engages in forward commitment and when-issued transactions, it
relies on the seller to consummate the transaction. The failure of the issuer or
seller to consummate the transaction may result in the Fund's losing the
opportunity to obtain a price and yield considered to be advantageous. The
purchase of securities on a when-issued or forward commitment basis also
involves a risk of loss if the value of the security to be purchased declines
prior to the settlement date.

                                       12
<PAGE>


On the date the Fund  enters  into an  agreement  to  purchase  securities  on a
when-issued or forward  commitment  basis, the Fund will segregate in a separate
account cash or liquid securities equal in value to the Fund's commitment. These
assets will be valued daily at market, and additional cash or securities will be
segregated  in a  separate  account to the  extent  that the total  value of the
assets in the account declines below the amount of the when-issued  commitments.
Alternatively, the Fund may enter into offsetting contracts for the forward sale
of other securities that it owns.

Swaps,  Caps,  Floors  and  Collars.  As one way of  managing  its  exposure  to
different types of investments, the Fund may enter into interest rate swaps, and
other types of swap  agreements such as caps,  collars and floors.  In a typical
interest  rate  swap,  one party  agrees  to make  regular  payments  equal to a
floating  interest  rate  times a  "notional  principal  amount,"  in return for
payments equal to a fixed rate times the same amount,  for a specified period of
time.  Swaps may also depend on other  prices or rates,  such as the value of an
index or mortgage prepayment rates.

In a typical cap or floor  agreement,  one party  agrees to make  payments  only
under  specified  circumstances,  usually in return for  payment of a fee by the
other party. For example, the buyer of an interest rate cap obtains the right to
receive  payments  to the  extent  that a  specified  interest  rate  exceeds an
agreed-upon  level,  while the seller of an interest  rate floor is obligated to
make  payments  to the extent  that a  specified  interest  rate falls  below an
agreed-upon level. An interest rate collar combines elements of buying a cap and
selling a floor.

Swap agreements will tend to shift the Fund's investment  exposure from one type
of  investment to another.  Caps and floors have an effect  similar to buying or
writing options. Depending on how they are used, swap agreements may increase or
decrease the overall  volatility of the Fund's  investments  and its share price
and yield.

Swap agreements are sophisticated  hedging  instruments that typically involve a
small  investment  of cash  relative to the  magnitude  of risks  assumed.  As a
result,  swaps can be highly volatile and may have a considerable  impact on the
Fund's  performance.  Swap  agreements  are  subject  to  risks  related  to the
counterpart's  ability to perform, and may decline in value if the counterpart's
credit worthiness deteriorates.  The Fund may also suffer losses if it is unable
to  terminate  outstanding  swap  agreements  or  reduce  its  exposure  through
offsetting transactions. The Fund will maintain in a segregated account with its
custodian,  cash or liquid,  high grade debt securities equal to the net amount,
if any,  of the  excess of the  Fund's  obligations  over its  entitlement  with
respect to swap, cap, collar or floor transactions.

Lending of Securities.  For purposes of realizing  additional  (taxable) income,
the Fund may lend  portfolio  securities  to  brokers,  dealers,  and  financial
institutions if the loan is collateralized by cash or U.S. Government securities
according to applicable regulatory requirements.  The Fund may reinvest any cash
collateral in short-term  securities and money market funds. When the Fund lends
portfolio  securities,  there is a risk that the borrower may fail to return the
securities  involved in the transaction.  As a result, the Fund may incur a loss
or, in the event of the  borrower's  bankruptcy,  the Fund may be  delayed in or
prevented from  liquidating  the collateral.  It is a fundamental  policy of the
Fund not to lend portfolio  securities having a total value exceeding 33 1/3% of
its total assets.

Short-Term Trading and Portfolio Turnover. The Fund may attempt to maximize
current income through short-term portfolio trading. This will involve selling
portfolio instruments and purchasing different instruments to take advantage of
yield disparities in different segments of the market for government
obligations. Short- term trading may have the effect of increasing portfolio
turnover rate. The portfolio turnover rate for the Fund is calculated by
dividing the lower annual sales or purchases of portfolio securities (exclusive
of purchases or sales of all securities whose maturities at the time of
acquisition were 1 year or less) by the monthly average value of the securities
in the Fund during the year. A high rate of portfolio turnover (100% or greater)
involves correspondingly higher brokerage expenses. The Fund's portfolio
turnover rate is set forth in the table under the caption "Financial Highlights"
in the Prospectus.

Special Risks

The following  information as to certain special risks associated with investing
in New York  constitutes  only a brief  summary  and does  not  purport  to be a
complete description of the considerations associated with such investments. The
information is based in part on information from official  statements related to
securities offerings of New York issuers and is believed to be accurate.

The  following  section  provides  only a brief  summary of the complex  factors
affecting  the  financial  situation  in New York  and is  based on  information
obtained  from New York State (the "State" or "New York  State")  certain of its
authorities  and New York City  (the  "City"  or "New  York  City") as  publicly
available  on  the  date  of  this  Statement  of  Additional  Information.  The
information  contained  in  such  publicly  available  documents  has  not  been
independently  verified.  It  should  be  noted  that  the  creditworthiness  of
obligations issued by local issuers may be unrelated to the  creditworthiness of
the  State,  and that  there is no  obligation  on the part of the State to make
payment on such local  obligations  in the event of default in the  absence of a
specific guarantee of pledge provided by the State. It should also be noted that
the fiscal stability of New York State is related to the fiscal stability of New
York City and of the State's  Authorities.  New York State's experience has been
that if New York City or any other  major  political  subdivision  or any of the
State's  Authorities  suffers serious financial  difficulty,  the ability of New
York State, New York State's  political  subdivisions  (including New York City)
and the State's  Authorities to obtain financing in the public credit markets is
adversely affected. This results in part from the expectation that to the extent
that any Authority or local government experiences financial difficulty, it will
seek and receive New York State financial  assistance.  Moreover,  New York City
accounts for  approximately  40 percent of New York State's  population  and tax
receipts,  so New York City's financial integrity in particular affects New York
State  directly.  Accordingly,  if there should be a default by New York City or
any other major  political  subdivision or any of the State's  Authorities,  the
market value and  marketability  of all New York Tax-Exempt  Bonds issued by New
York State,  its political  subdivisions  and Authorities  ("New York Tax-Exempt
Bonds") could be adversely  affected.  This would have an adverse  effect on the
asset value and liquidity of the Fund, even though  securities of the defaulting
entity may not be held by the Fund.

State Economy

The State economic  forecast for 1999 and 2000 has been raised slightly from the
August  Financial Plan forecast.  Continued growth is projected in 1999 and 2000
for employment,  wages, and personal income,  although,  for 2000, a slowdown in
the growth rate of  employment  is  expected.  The growth of personal  income is
projected to decrease  from 5.2% in 1998 to 4.8% in 1999,  and then grow 4.9% in
2000.  The growth in average wages is expected to outpace the inflation  rate in
both 1999 and 2000.  Overall  employment  growth is expected to be 2.0% in 1999,
almost the same as in 1998, but is expected to drop 1.7% in 2000, reflecting the
slowing  growth  of  the  national  economy,  continued  spending  restraint  in
government,  constraints  in labor supply,  and continued  restructuring  in the
manufacturing, health care, and banking sectors.

1999-2000  Fiscal Year.  The State's  current fiscal year began on April 1, 1999
and ends on March 31,  2000.  On March 31,  1999,  the  State  adopted  the debt
service  portion of the State budget for the 1999-2000  fiscal year; four months
later,  on August 4, 1999, it enacted the remainder of the budget.  The Governor
approved the budget as passed by the Legislature. Prior to passing the budget in
its entirety for the current fiscal year, the State enacted  appropriations that
permitted the State to continue its operations.

                                       14
<PAGE>


In 1999-2000, General Fund disbursements, including transfers to support capital
projects,  debt service and other funds,  are  estimated at $37.36  billion,  an
increase of $868 million or 2.38% over 1998-1999.  Projected  spending under the
1999-2000  enacted budget is $215 million above the Governor's  Executive Budget
recommendations,  including 30-day amendments.  This change is the net result of
spending actions that occurred during  negotiations on the Budget.  The increase
in General Fend spending is comprised of $1.1 billion in  legislative  additions
to the Executive  Budget  (primarily in education),  offset by various  actions,
including reestimates of required spending based on year-to-date results and the
identification  of certain other  resources that offset  spending,  such as $250
million  from  commencing  the process of  privatizing  the Medical  Malpractice
Insurance  Association  (MMIA),  $250  million  from the  retention  of the Debt
Reduction  Reserve Fund within the General Fund and about $100 million in excess
fund balances.  The MMIA was  established  in 1983 to provide  excess  liability
insurance  to  doctors  and  medical  providers.  Legislation  enacted  with the
1999-2000  budget  initiates  the process of MMIA  privatization  and  transfers
excess fund balances to the State.

1998-1999 Fiscal Year.  Adoption of the State's fiscal 1998-1999 budget occurred
almost on schedule with the final legislative  program passing on April 18, 1998
and being enacted by the Governor on April 25, 1998. The budget contains several
new  provisions  to accelerate  local  property and income tax relief for senior
citizens,  expansion  of  income  tax  credits,  tax and fee  reductions  and an
accelerated  phase-out of assessments on medical providers.  In conjunction with
continuing  the tax reduction  program,  the Fiscal  1998-1999  budget  contains
increased spending for public schools,  special needs programs and the State and
City university systems. Overall, this budget calls for total state expenditures
to rise by 8% and revenues by about 6%.

 The Fiscal  1998-1999  General Fund  anticipates  increasing  both revenues and
expenditures by 7%.  Principally,  the additional  revenues are expected to stem
from a  significant  expansion  of personal  income taxes being offset by slight
reductions in business taxes, other revenues and transfers.  Planned expenditure
increases focus on expanding education programs, grants to local governments and
meeting state operating needs. At the end of Fiscal 1998-1999,  the General Fund
projects a closing fund  balance of $1.4  billion  composed of $760 million in a
reserve  for future  needs,  a $400  million  balance  in the Tax  Stabilization
Reserve Fund,  $158 million in the  Community  Projects Fund and $100 million in
the Contingency Reserve Fund.

Capital Project Fund spending is forecast to exceed $4.1 billion, an increase of
16%,  in  Fiscal   1998-1999.   Major   components   of  this  program   feature
transportation, environmental projects related to the 1996 Clean Water/Clean Air
Act, and prison capacity enhancement projects.

1997-1998  Fiscal Year. The State's fiscal  1997-1998  budget for was adopted by
the  Legislature,  more than four  months  after the start of the fiscal year on
April 1, 1997. It featured  multi-year tax reductions,  including a State funded
property  and local income tax  reduction  program,  estate tax relief,  utility
gross receipts tax  reductions,  permanent  reductions in the State sales tax on
clothing,  and  elimination  of  assessments  on medical  providers.  Based upon
preliminary results, the improving state economy generated revenues in excess of
moderate expenditure levels. Due to phasing and economic projections, the impact
of these tax  reductions  should  not begin to  materially  affect  the  outyear
projections until fiscal year 1999-2000.

The State projects to end fiscal year 1997-1998 with a combined funds  operating
surplus  of $2  billion  and  expects  that for the first time since 1982 it has
eliminated its accumulated  deficit (GAAP basis). At year-end,  the State should
show an  accumulated  surplus of $567  million.  This  improvement  reflects  an
expectation an increase of 7.4% in State combined fund revenues and  expenditure
growth of 5.7% over 1996-1997.

                                       15
<PAGE>


Final General Fund figures project a surplus of $205 million or 0.6% of expected
revenues.  Compared  with  FY1996-97,  disbursements  should show an increase of
$1.45  billion,  or 4.4% and revenues by $1.5 billion or 4.6%. By category,  the
largest gains in disbursements  should relate to general operating  expenses and
debt service  obligations  while social service delivery  programs realized only
modest  increases.  On the  revenue  side,  the  General  Fund  appears  to have
benefited from increased collections of personal income taxes and user taxes and
fees.  The projected  figures  should result in the provision of $638 million in
General Fund reserves  including a projected  balance of $400 million in the Tax
Stabilization  Reserve  Fund,  and  a  projected  $68  million  balance  in  the
Contingency Reserve Fund and $170 million in a Community Projects Reserve.

1996-1997 Fiscal Year. The state ended the 1996-1997 fiscal year with a combined
Governmental  Funds  operating  surplus  of  $2.1  billion,  which  included  an
operating  surplus in the General  Funds of $1.9  billion,  in Capital  Projects
Funds of $98 million and in the Special Revenue Funds of $65 million,  offset in
part by an operating deficit of $37 million in the Debt Service Funds.

General  Fund  receipts  totaled $33 billion  during the Fiscal  Year.  Revenues
increased  $1.91  billion  (nearly  6.0%) over the prior fiscal  year.  Personal
income taxes grew $620 million (3.6%),  despite the  implementation of scheduled
tax cuts. This increase is  attributable to moderate  employment and wage growth
and the strong financial markets during 1996.

The General Fund  reported an operating  surplus of $1.93 billion for the fiscal
year,  as compared to $380  million for the previous  fiscal year.  Debt Service
Funds ended the 1996-1997 fiscal year with an operating  deficit of $37 million,
as a  result,  the  accumulated  fund  balance  declined  to $1.90  billion.  An
operating  surplus was  reported for the Special  Revenue  Funds and the Capital
Projects  Funds  of $65  million  and $98  million  respectively,  bringing  the
accumulated  fund balance of the Special  Revenue Fund to $532 million,  and the
accumulated fund balance of the Capital Projects Fund to $614 million.

Expenditures  increased  $830 million or 2.6% from the prior  fiscal  year.  The
largest increases occurred in pension contributions,  which were up $514 million
(198.2%),  and State aid for  education  spending,  which was up $351  million (
3.4%).  The  pension  increase  was due to the State  paying off its 1984-85 and
1985-86  pension  amortization  liability.  Modest  increases in other State aid
spending was offset by a decline in social services  expenditure of $157 million
(1.7%).

Ratings

The  current  General  Obligation  ratings  for the  State of New York are A2 by
Moody's,  A+ by S&P and A+ by Fitch  Investors  Services.  On  November 9, 1999,
Standard and Poor's upgraded their rating for the State of New York from to A to
A+ with a Stable Outlook.

Credit Considerations

Current Budget.  The Fiscal Year 1999-2000 budget,  which projects to generate a
significant   surplus,   contains   certain  risks  related  to  the  underlying
assumptions of the budget.  These risks relate  primarily to the economy and tax
collections  over the second half of the fiscal year.  In the event that affects
of the financial  problems and general economic slowdowns in the global economy,
and changes in the health care  industry or other sectors could result in slower
economic growth and a deterioration in expected State revenues.

                                       16

Welfare Reform.  The new welfare reform program initiated in November 1997 could
impact state  expenditures  in the event of a slowdown in the state economy.  To
date,  the new  legislation  which  aims to reduce  welfare  rolls by  rewarding
enabling more recipients to work appears to have produced program  efficiencies.
A general slowdown in the state economy especially in New York City could thwart
many of the  gains  achieved  by this  program  and shift  additional  financial
burdens to state and local governments.

Authorities  The fiscal  stability of New York is related,  at least in part, to
the fiscal  stability of its localities  and  Authorities.  Authorities  are not
subject to the constitutional  restrictions on the incurrence of debt that apply
to New York State.  Authorities may issue bonds and notes within the amounts of,
and as otherwise restricted by, their legislative authorization.

Authorities  are  generally  supported  by revenues  generated  by the  projects
financed or operated,  such as fares, user fees on bridges,  highway tolls, mass
transportation  and rentals for  dormitory  rooms and housing.  In recent years,
however, New York has provided financial assistance through  appropriations,  in
some cases of a recurring nature, to certain Authorities for operating and other
expenses and, in fulfillment of its commitments on moral obligation indebtedness
or otherwise,  for debt service.  This  assistance is expected to continue to be
required in future years.  Failure of New York to appropriate  necessary amounts
or to take other  action to permit  the  Authorities  to meet their  obligations
could result in a default by one or more of the  Authorities.  If a default were
to occur, it would likely have a significant  adverse effect on the market price
of obligations of the State and its Authorities. As of March 31, 1997, there was
outstanding a $35.1 billion aggregate principal amount of bonds and notes issued
by  Authorities  which were either  guaranteed  by the State or supported by the
State through  lease-purchase and  contractual-obligation  arrangements or moral
obligation provisions.

Agencies  and  Localities  Beginning  in 1975 (in  part as a result  of the then
current New York City and UDC financial crises),  various localities of New York
State began experiencing difficulty in marketing their securities.  As a result,
certain  localities,  in addition to New York City, have  experienced  financial
difficulties  leading to  requests  for State  assistance.  If future  financial
difficulties cause agencies or localities to seek special State assistance, this
could  adversely  affect  New  York  State's  ability  to pay  its  obligations.
Similarly, if financial difficulties of New York State result in New York City's
inability to meet its regular aid  commitments or to provide  further  emergency
financing,  issuers may default on their  outstanding  obligations,  which would
affect the  marketability  of debt  obligations  of New York,  its  agencies and
municipalities such as the New York Municipal Obligations held by the Fund.

Reductions  in  Federal  spending  could  materially  and  adversely  affect the
financial  condition  and budget  projections  of New York  State's  localities.
Should  localities  be  adversely  affected by Federal  cutbacks,  they may seek
additional  assistance  from the State  which  might,  in turn,  have an adverse
impact on New York State's ability to maintain a balanced budget.

New York City In 1975, New York City encountered  severe financial  difficulties
which impaired the borrowing  ability of New York City, New York State,  and the
Authorities. New York City lost access to public credit markets and was not able
to sell debt to the public until 1979.

                                       17
<PAGE>


As a result of the City's financial  difficulties,  certain  organizations  were
established  to provide  financial  assistance and oversee and review the City's
financing. These organizations continue to exercise various monitoring functions
relating to the City's financial position.

New York City has  maintained a balanced  budget since 1981, and has retired all
of its federally guaranteed debt. As a result of the City's success in balancing
its budget,  certain  restrictions imposed on the City by the New York Financial
Control Board (the "Control Board"), which was created in response to the City's
1975 fiscal  crises,  have been  suspended.  Those  restrictions,  including the
Control Board's power to approve or disapprove certain contracts,  long-term and
short-term  borrowings and the four-year financial plan of the City, will remain
suspended unless and until, among other things, there is a substantial threat of
an actual failure by New York City to pay debt service on its notes and bonds or
to keep  its  operating  deficits  below  $100  million.  Although  the City has
maintained  a balanced  budget in recent  years,  the ability to balance  future
budgets is contingent  upon actual versus  expected  levels of Federal and State
Aid and the effects of the economy on City revenues and services.

The City requires certain amounts of financing for seasonal and capital spending
purposes.  The City has issued $1.1 billion of short-term obligations to finance
the City's  current  estimate of its  seasonal  financing  needs during its 1998
fiscal year. The City's capital financing program projects  long-term  financing
requirements  of  approximately  $16.4  billion for the City's fiscal years 1999
through   2002  for  the   construction   and   rehabilitation   of  the  City's
infrastructure  and other fixed assets. The major capital  requirements  include
expenditures  for the City's  water  supply  system,  sewage and waste  disposal
systems, roads, bridges, mass transit, schools and housing. In Fiscal Year 1998,
the New York City Transitional  Finance Authority  successfully issued over $650
million in asset back bonds to finance a portion of the City's  capital  program
and help avoid  exceeding  its State  Constitutional  general debt limit for the
City.

New York City buoyed by a rebounding  economy  expects to post a surplus of more
than $2 billion  for Fiscal  Year 1998.  The strong  performance  stems from the
City's maintenance of spending discipline and the projected receipt of over $1.6
billion  in  unexpected  personal  income,  business  and  sales  tax  revenues.
Continuation of the City's ability to adhere to fiscal  controls,  close outyear
projected funding shortfalls and the region's growing economy,  both Moody's and
Standard  & Poor's  raised  their  ratings  on New York City into the A category
during 1998. The current General Obligation ratings for the City of New York are
A3 by Moody's, A- by S&P and A- by Fitch Investors Services.

New York cities and towns have lagged the rest of the nation in recovering  from
the recession of 1992.  The impact of this gradual yet improving  economic trend
upon local  government  revenues  have been offset in part by  increasing  local
assistance  support from the state. The 1998-1999  enacted budget projects total
receipts  of $37.6  billion for the State's  General  Fund,  an increase of $3.0
billion  from the prior  fiscal  year.  State  General  Fund  disbursements  and
transfers  will be $2.4 billion above the level of  disbursements  in 1997-1998.
Grants to local  governments,  including  are  anticipated  to  increase  by $37
million from the prior fiscal year to over $800 million.

Certain  localities in addition to the City could have financial problems which,
if significant,  could lead to requests for additional State  assistance  during
the  State's  1998-99  fiscal  year and  thereafter.  To the extent the State is
constrained by its financial  condition,  State  assistance to localities may be
further reduced,  compounding the serious fiscal constraints already experienced
by many  local  governments.  Localities  also face  anticipated  and  potential
problems  resulting  from  pending  litigation  (including  challenges  to local
property tax assessments), judicial decisions and socio-economic trends.

Certain  counties  and other  local  governments  have  encountered  significant
financial  difficulties,  including Nassau County and Suffolk County (which each
received  approval by the  legislature  to issue deficit  notes).  The State has
imposed  financial  control on the City of New York from 1977 to 1986 and on the
City of Yonkers in 1984, 1988 and 1989, and the City of Troy commencing in 1995,
under an appointed  control  board in response to fiscal crises  encountered  by
these municipalities.

Litigation.  Certain litigation pending against New York State, its subdivisions
and their officers and employees  could have a substantial or long-term  adverse
effect on State finances. Among the more significant of these lawsuits are those
that  involve:  (i) the  validity  and  fairness of certain  eighteenth  century
agreements  and treaties by which Oneida and Cayuga  Indian  tribes  transferred
title to the State of  approximately  five million  acres of land in central New
York;  (ii)  certain  aspects of the  State's  Medicaid  rates and  regulations,
including  reimbursements  to  providers  of  mandatory  and  optional  Medicaid
services;  (iii) the care and housing for individuals released from State mental
health  facilities;  (iv)  changes in  Medicaid  reimbursement  methodology  for
nursing  home care;  (v) the State's  practice  of  reimbursing  certain  mental
hygiene patient-care  expenses with the client's Social Security benefits;  (vi)
adequacy of shelter allowance provided to recipients of public assistance; (vii)
contract and tort claims; (viii) alleged violation of the Commerce Clause of the
United States Constitution; (ix) enforcement of sales and excise tax collections
of tobacco and motor fuel sold to non-Indian  customers on Indian  reservations;
(x)  legality of the Clean  Water/Clean  Air Bond Act of 1996;  and (xi) alleged
responsibility  of New York  State  officials  to  assist  in  remedying  racial
segregation in the City of Yonkers.

The  investment  objectives  and  policies  described  above  under the  caption
"Investment  Objective and Policies" are not  fundamental  and may be changed by
the Trustees without shareholder approval. The policy of the Fund requiring that
under  normal  circumstances  at least 80% of the Fund's  net assets  consist of
Tax-Exempt  Bonds is fundamental and may not be changed by the Trustees  without
shareholder approval.

Investment Restrictions

Fundamental Investment  Restrictions.  The fundamental  investment  restrictions
will not be changed  for the Fund  without  the  approval  of a majority  of the
Fund's  outstanding  voting securities which, as used in the Prospectus and this
Statement of Additional Information, means the approval by the lesser of (1) the
holders of 67% or more of the  Fund's  shares  represented  at a meeting if more
than 50% of the Fund's  outstanding  shares are present in person or by proxy at
that meeting or (2) more than 50% of the Fund's outstanding shares.

 The Fund may not:

         (1)      Issue senior securities, except as permitted by paragraphs (2)
                  and (7) below. For purposes of this restriction,  the issuance
                  of  shares of  beneficial  interest  in  multiple  classes  or
                  series, the purchase or sale of options, futures contracts and
                  options  on  futures  contracts,   forward  commitments,   and
                  repurchase  agreements  entered  into in  accordance  with the
                  Fund's  investment  policies,  and  the  pledge,  mortgage  or
                  hypothecation  of the  Fund's  assets  within  the  meaning of
                  paragraph (3) below are not deemed to be senior securities.

         (2)      Borrow  money,  except from banks as a  temporary  measure for
                  extraordinary  emergency  purposes in amounts not to exceed 33
                  1/3%  of  the  Fund's  total  assets   (including  the  amount
                  borrowed)  taken at market  value.  The Fund will not purchase
                  securities while borrowings are outstanding.

         (3)      Pledge,  mortgage or hypothecate its assets,  except to secure
                  indebtedness permitted by paragraph (2) above and then only if

                  of the Fund's total assets taken at market value.

         (4)      Act as an underwriter, except to the extent that in connection
                  with  the  disposition  of Fund  securities,  the  Fund may be
                  deemed to be an underwriter for purposes of the Securities Act
                  of 1933.  The Fund may also  participate as part of a group in
                  bidding for the purchase of Tax-Exempt  Bonds directly from an
                  issuer in order to take  advantage of the lower purchase price
                  available to members of such groups.

                                       19

         (5)      Purchase or sell real estate or any interest therein, but this
                  restriction  shall  not  prevent  the Fund from  investing  in
                  Tax-Exempt Bonds secured by real estate or interests therein.

         (6)      Make  loans,  except  that the  Fund  (1) may  lend  portfolio
                  securities in accordance with the Fund's  investment  policies

                  market value,  (2) enter into repurchase  agreements,  and (3)
                  purchase all or a portion of an issue of debt securities, bank
                  loan  participation  interests,  bank certificates of deposit,
                  bankers' acceptances,  debentures or other securities, whether
                  or not the purchase is made upon the original  issuance of the
                  securities.

         (7)      Purchase or sell  commodities or commodity  contracts or puts,
                  calls or combinations  of both,  except options on securities,
                  securities indices,  currency and other financial instruments,
                  futures contracts on securities,  securities indices, currency
                  and other  financial  instruments  and options on such futures
                  contracts, forward commitments,  interest rate swaps, caps and
                  floors,  securities  index put or call warrants and repurchase
                  agreements   entered  into  in  accordance   with  the  Fund's
                  investment policies.

         (8)      Purchase the securities of issuers  conducting their principal
                  business  activity in the same industry if,  immediately after
                  such purchase,  the value of its  investments in such industry
                  would  exceed 25% of its total assets taken at market value at
                  the time of each investment. (Tax- Exempt Bonds and securities
                  issued or guaranteed by the United States  Government  and its
                  agencies  and   instrumentalities  are  not  subject  to  this
                  limitation.)

         (9)      Purchase   securities  of  an  issuer  (other  than  the  U.S.
                  Government,  its  agencies  or  instrumentalities),   if  such
                  purchase  would cause more than 10 percent of the  outstanding
                  voting securities of such issuer to be held by the Fund.

Non-fundamental Investment Restrictions. The following investment restrictions
are designated as non-fundamental and may be changed by the Trustees without
shareholder approval:

The Fund may not:

         (1)      Except as permitted by fundamental  investment restriction (4)
                  above,  participate on a joint or  joint-and-several  basis in
                  any securities  trading account.  The "bunching" of orders for
                  the sale or purchase of marketable  Fund securities with other
                  accounts   under  the   management  of  the  Adviser  to  save
                  commissions  or to average  prices among them is not deemed to
                  result in a joint securities trading account.

         (2)      Purchase  securities  on margin or make short sales  unless by
                  virtue of its ownership of other securities,  the Fund has the
                  right to obtain  securities  equivalent  in kind and amount to
                  the  securities  sold short and, if the right is  conditional,
                  the sale is made  upon the same  conditions,  except  that the
                  Fund may obtain such  short-term  credits as may be  necessary
                  for the clearance of purchases and sales of securities.

                                       20
<PAGE>


         (3)      Purchase a security if, as a result,  (i) more than 10% of the
                  Fund's  total assets  would be invested in the  securities  of
                  other investment companies, (ii) the Fund would hold more than
                  3% of the  total  outstanding  voting  securities  of any  one
                  investment  company, or (iii) more than 5% of the Fund's total
                  assets  would  be  invested  in  the  securities  of  any  one
                  investment company.  These limitations do not apply to (a) the
                  investment  of  cash  collateral,  received  by  the  Fund  in
                  connection with lending the Fund's  portfolio  securities,  in
                  the  securities  of open-end  investment  companies or (b) the
                  purchase  of shares of any  investment  company in  connection
                  with a merger,  consolidation,  reorganization  or purchase of
                  substantially all of the assets of another investment company.
                  Subject to the above percentage limitations,  the Fund may, in
                  connection  with the  John  Hancock  Group  of Funds  Deferred
                  Compensation Plan for Independent Trustees/Directors, purchase
                  securities  of  other  investment  companies  within  the John
                  Hancock Group of Funds.

         (4)      invest more than 15% of its net assets in illiquid securities.

If a percentage  restriction on investment or utilization of assets as set forth
above  is  adhered  to at the time an  investment  is made,  a later  change  in
percentage  resulting from changes in the value of the Fund's assets will not be
considered a violation of the restriction.

THOSE RESPONSIBLE FOR MANAGEMENT

The  business  of the Fund is  managed  by the  Trustees  of the Trust who elect
officers who are responsible  for the day-to-day  operations of the Fund and who
execute  policies  formulated  by the Trustees.  Several of the officers  and/or
Trustees  of the Fund are also  officers  and/or  directors  of the  Adviser  or
officers and Trustees of the Fund's principal  distributor,  John Hancock Funds,
Inc. ("John Hancock Funds").

Investment Advisory And Other Services

The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts 02199-7603,
was  organized in 1968 and has more than $30 billion in assets under  management
in its  capacity as  investment  adviser to the Fund and other funds in the John
Hancock  group of funds as well as  institutional  accounts.  The  Adviser is an
affiliate  of the  Life  Company,  one  of the  most  recognized  and  respected
financial institutions in the nation. With total assets under management of more
than $100  billion,  the Life Company is one of the ten largest  life  insurance
companies  in the United  States,  and carries a high rating from  Standard  and
Poor's and A.M. Best. Founded in 1862, the Life Company has been serving clients
for over 130 years.

The Fund has entered  into an  investment  management  contract  (the  "Advisory
Agreement")  with the Adviser  which was  approved  by the Fund's  shareholders.
Pursuant to the Advisory Agreement,  the Adviser will: (a) furnish  continuously
an  investment  program  for the  Fund and  determine,  subject  to the  overall
supervision and review of the Trustees,  which investments  should be purchased,
held,  sold or exchanged,  and (b) provide  supervision  over all aspects of the
Fund's  operations  except those which are  delegated  to a custodian,  transfer
agent or other agent.

The Fund bears all costs of its organization and operation, including but not
limited to expenses of preparing, printing and mailing all shareholders'
reports, notices, prospectuses, proxy statements and reports to regulatory
agencies; expenses relating to the issuance, registration and qualification of
shares; government fees; interest charges; expenses of furnishing to
shareholders their account statements; taxes; expenses of redeeming shares;
brokerage and other expenses connected with the execution of portfolio
securities transactions; expenses pursuant to the Fund's plan of distribution;
fees and expenses of custodians including those for keeping books and accounts,
maintaining a committed line of credit, and calculating the net asset value of

                                       29

shares; fees and expenses of transfer agents and dividend disbursing agents;
legal, accounting, financial, management, tax and auditing fees and expenses of
the Fund (including an allocable portion of the cost of the Adviser's employees
rendering such services to the subject Fund); the compensation and expenses of
Trustees who are not otherwise affiliated with the Trust, the Adviser or any of
their affiliates; expenses of Trustees' and shareholders' meetings; trade
association memberships; insurance premiums; and any extraordinary expenses.

As compensation for its services under the Advisory Agreement, the Fund pays the
Adviser  monthly a fee based on a stated  percentage  of the  average  daily net
assets of the Fund as follows:


Net Asset Value                                            Annual Rate
- ---------------                                            -----------

First $250 million                                           0.500%
Next $250 million                                            0.450%
Next $500 million                                            0.425%
Next $250 million                                            0.400%
Amounts over $1,250,000,000                                  0.300%

From time to time, the Adviser may reduce its fee or make other  arrangements to
limit the Fund's  expenses to a specified  percentage  of its average  daily net
assets.  The  Adviser  retains the right to reimpose a fee and recover any other
payments to the extent that,  at the end of any fiscal year,  the Fund's  annual
expenses fall below this limit.

For the years ended August 31, 1997,  1998 and 1999,  the management fee paid by
the Fund to the Adviser amounted to $63,549,  $58,219 and $97,128, for services,
respectively.

Securities  held by the  Fund may  also be held by  other  funds  or  investment
advisory  clients for which the  Adviser or its  affiliates  provide  investment
advice.   Because  of  different  investment  objectives  or  other  factors,  a
particular  security  may be bought for one or more funds or clients when one or
more are selling the same  security.  If  opportunities  for purchase or sale of
securities  by the  Adviser or for other  funds or clients for which the Adviser
renders  investment  advice arise for  consideration  at or about the same time,
transactions  in such  securities  will be made,  insofar as  feasible,  for the
respective  funds or clients in a manner deemed equitable to all of them. To the
extent that transactions on behalf of more than one client of the Adviser or its
affiliates may increase the demand for securities  being purchased or the supply
of securities being sold, there may be an adverse effect on price.

Pursuant to the Advisory  Agreement,  the Adviser is not liable for any error of
judgment or mistake of law or for any loss  suffered  by the Fund in  connection
with the matters to which their respective  Advisory Agreement relate,  except a
loss resulting from willful  misfeasance,  bad faith or gross  negligence on the
part of the Adviser in the performance of its duties or from reckless  disregard
of the obligations and duties under the Advisory Agreement.

Under the Advisory Agreement, the Fund may use the name "John Hancock" or any
name derived from or similar to it only for so long as the Advisory Agreement or
any extension, renewal or amendment thereof remains in effect. If the Fund's
Advisory Agreement is no longer in effect, the Fund (to the extent that it
lawfully can) will cease to use such name or any other name indicating that it
is advised by or otherwise connected with the Adviser. In addition, the Adviser
or the Life Company may grant the non-exclusive right to use the name "John
Hancock" or any similar name to any other corporation or entity, including but
not limited to any investment company of which the Life Company or any
subsidiary or affiliate thereof or any successor to the business of any
subsidiary or affiliate thereof shall be the investment adviser.

The continuation of the Advisory Agreement and Distribution Agreement (discussed
below) was  approved by all of the  Trustees.  The  Advisory  Agreement  and the
Distribution  Agreement will continue in effect from year to year, provided that
its  continuance  is approved  annually both (i) by the holders of a majority of
the outstanding voting securities of the Trust or by the Trustees, and (ii) by a
majority of the Trustees who are not parties to the  Agreement,  or  "interested
persons" of any such  parties.  Both  Agreements  may be  terminated  on 60 days
written notice by any party or by a vote of a majority of the outstanding voting
securities of the Fund and will terminate automatically if assigned.

Accounting and Legal Services  Agreement The Trust,  on behalf of the Fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this Agreement,  the Adviser  provides the Fund with certain tax,  accounting
and legal  services.  For the fiscal years ended August 31, 1997, 1998 and 1999,
the Fund paid the Adviser $10,630, $9,800 and $9,263, respectively, for services
under this Agreement.


Personnel of the Adviser and its affiliates may trade securities for their
personal accounts. The Fund also may hold, or may be buying or selling, the same
securities. To prevent the Fund from being disadvantaged, the Adviser and its
affiliates and the Fund have adopted a code of ethics which restricts the
trading activity of those personnel.


Distribution ContractS

The Fund has a  Distribution  Agreement  with  John  Hancock  Funds.  Under  the
agreement,  John  Hancock  Funds is  obligated  to use its best  efforts to sell
shares of each class on behalf of the Fund.  Shares of the Fund are also sold by
selected  broker-dealers (the "Selling Brokers") which have entered into selling
agency agreements with John Hancock Funds.  These Selling Brokers are authorized
to designate other  intermediaries  to receive purchase and redemption orders on
behalf of the Fund.  John Hancock Funds  accepts  orders for the purchase of the
shares  of the  Fund  that are  continually  offered  at net  asset  value  next
determined, plus an applicable sales charge, if any. In connection with the sale
of Fund shares, John Hancock Funds and Selling Brokers receive compensation from
a sales charge imposed,  in the case of Class A shares,  at the time of sale. In
the  case of  Class B or  Class  C  shares,  the  broker  receives  compensation
immediately but John Hancock Funds is compensated on a deferred basis.

Total  underwriting  commissions  for sales of the Fund's Class A shares for the
fiscal  years ended August 31, 1997,  1998 and 1999 were  $155,262,  $18,852 and
$90,254,  respectively,  and $20,879,  $4,561, and $17,861,  respectively,  were
retained by John  Hancock  Funds in 1997,  1998 and 1999.  The  remainder of the
underwriting commissions were reallowed to dealers.

The Fund's Trustees adopted Distribution Plans with respect to each class of
shares (the "Plans") pursuant to Rule 12b-1 under the Investment Company Act of
1940. Under the Plans, the Fund will pay distribution and service fees at an
aggregate annual rate of up to 0.30% for Class A shares and 1.00% for Class B
and Class C shares, of the Fund's average daily net assets attributable to
shares of that class. However, the service fee will not exceed 0.25% of the
Fund's average daily net assets attributable to each class of shares. The
distribution fees will be used to reimburse John Hancock Funds for its
distribution expenses, including but not limited to: (i) initial and ongoing
sales compensation to Selling Brokers and others (including affiliates of John
Hancock Funds) engaged in the sale of Fund shares; (ii) marketing, promotional
and overhead expenses incurred in connection with the distribution of Fund
shares; and (iii) with respect to Class B and Class C shares only, interest
expenses on unreimbursed distribution expenses. The service fees will be used to
compensate Selling Brokers and others for providing personal and account
maintenance services to shareholders. In the event the John Hancock Funds is not

                                       31
<PAGE>


fully reimbursed for payments or expenses under the Class A Plan, these expenses
will not be carried beyond twelve months from the date they were incurred.
Unreimbursed expenses under the Class B and Class C Plans will be carried
forward together with interest on the balance of these unreimbursed expenses.
The Fund does not treat unreimbursed expenses under the Class B and Class C
Plans as a liability of the Fund, because the Trustees may terminate Class B
and/or Class C Plans at any time with no additional liability for these expenses
to the shareholders and the Fund. For the fiscal year ended August 31, 1999, an
aggregate of $177,742 of distribution expenses or 2.18% of the average net
assets of the Fund's Class B shares was not reimbursed or recovered by John
Hancock Funds through the receipt of deferred sales charges or Rule 12b-1 fees
in prior periods. For the period from April 1, 1999, August 31, 1999, an
aggregate of $0 distribution expenses or 0% of the average net assets of the
Fund's Class C shares was not reimbursed or recovered by John Hancock Funds
through the receipt of deferred sales charges or Rule 12b-1 fees.

The Plans and all amendments were approved by the Trustees, including a majority
of the  Trustees  who are not  interested  persons  of the  Fund and who have no
direct or  indirect  financial  interest  in the  operation  of the  Plans  (the
"Independent  Trustees"),  by votes  cast in person at  meetings  called for the
purpose of voting on such Plans.

Pursuant to the Plans, at least  quarterly,  John Hancock Funds provide the Fund
with a written  report of the amounts  expended  under the Plans and the purpose
for which these  expenditures  were made. The Trustees review these reports on a
quarterly basis to determine their continued appropriateness.

The  Plans  provide  that  they will  continue  in effect  only so long as their
continuance is approved at least annually by a majority of both the Trustees and
Independent  Trustees.  The Plans  provide that they may be  terminated  without
penalty, (a) by vote of a majority of the Independent Trustees, (b) by a vote of
a majority  of the Fund's  outstanding  shares of the  applicable  class upon 60
days' written notice to John Hancock Funds,  and (c)  automatically in the event
of  assignment.  The  Plans  further  provide  that they may not be  amended  to
increase  the  maximum  amount of the fees for the  services  described  therein
without the approval of a majority of the outstanding shares of the class of the
Fund which has voting rights with respect to that Plan. Each Plan provides, that
no material  amendment to the Plans will be effective unless it is approved by a
majority  vote of the Trustees  and the  Independent  Trustees of the Fund.  The
holders of Class A, Class B and Class C shares have exclusive voting rights with
respect to the Plan applicable to their respective class of shares.  In adopting
the Plans, the Trustees concluded that, in their judgment, there is a reasonable
likelihood  that the Plans will benefit the holders of the  applicable  class of
shares of the Fund.

Amounts paid to John  Hancock  Funds by any class of shares of the Fund will not
be used to pay the expenses  incurred  with respect to any other class of shares
of the Fund;  provided,  however,  that expenses  attributable  to the Fund as a
whole will be allocated,  to the extent permitted by law, according to a formula
based upon gross  sales  dollars  and/or  average  daily net assets of each such
class,  as may be approved  from time to time by vote of a majority of Trustees.
From time to time,  the Fund may  participate in joint  distribution  activities
with other funds and the costs of those  activities will be borne by the Fund in
proportion to the relative net asset value of the participating Fund.

During the fiscal year ended August 31, 1999,  the Fund paid John Hancock  Funds
the following amounts of expenses in connection with their services.

SALES COMPENSATION

As part of their business  strategies,  the Fund, along with John Hancock Funds,
pays compensation to financial services firms that sell the Fund's shares. These
firms  typically  pass along a portion of this  compensation  to your  financial
representative.


The two primary sources of compensation payments are (1) the 12b-1 that are paid
out of the Fund's  assets and sales  charges  paid by the  investors.  The sales
charges and 12b-1 fees are detailed in the  prospectus  and under  "Distribution
Contracts" in this  Statement of Additional  Information.  The portions of these
expenses  that are reallowed to financial  services  firms are shown on the next
page.

Whenever  you make an  investment  in the  Fund,  the  financial  services  firm
receives a  reallowance,  as described  below.  The firm also receives the first
year's  service  fee at this  time.  Beginning  with the  second  year  after an
investment is made,  the financial  services firm receives an annual service fee
of 0.25% of its total  eligible fund net assets.  This fee is paid  quarterly in
arrears by the Fund.

In addition, from time to time, John Hancock Funds, at its expense, may provide
significant additional compensation to financial services firms which sell or
arrange for the sale of shares of the Fund. Such compensation provided by John
Hancock Funds may include, for example, financial assistance to financial
services firms in connection with their conferences or seminars, sales or
training programs for invited registered representatives and other employees,
payment for travel expenses, including lodging, incurred by registered
representatives and other employees for such seminars or training programs,
seminars for the public, advertising and sales campaigns regarding one or more
Funds, and/or other financial services firms-sponsored events or activities.
From time to time, John Hancock Funds may make expense reimbursements for
special training of a financial services firm's registered representatives and
other employees in group meetings or to help pay the expenses of sales contests.
Other compensation, such as asset retention fees, finder's fees and
reimbursement for wire transfer fees, may be offered to the extent not
prohibited by law or any self-regulatory agency, such as the NASD.

      CDSC of 1.00% applies for each sale).

CDSC  revenues  collected by John Hancock  Funds may be used to pay  commissions
when there is no initial sales charge.

Net Asset Value

For purposes of  calculating  the net asset value ("NAV") of the Fund's  shares,
the following procedures are utilized wherever applicable.

Debt investment  securities are valued on the basis of valuations furnished by a
principal  market maker or a pricing  service,  both of which generally  utilize
electronic  data  processing  techniques  to  determine  valuations  for  normal
institutional  size trading units of debt securities  without exclusive reliance
upon quoted prices.

Short-term debt investments  which have a remaining  maturity of 60 days or less
are generally  valued at amortized  cost which  approximates  market  value.  If
market  quotations are not readily available or if in the opinion of the Adviser
any  quotation or price is not  representative  of true market  value,  the fair
value  of the  security  may be  determined  in good  faith in  accordance  with
procedures approved by the Trustees.

The NAV for each fund and class is determined  each business day at the close of
regular  trading on the New York Stock  Exchange  (typically  4:00 p.m.  Eastern
Time) by dividing a class' net assets by the number of its shares outstanding.


Initial Sales Charge on Class A AND CLASS C Shares


Shares of the Fund are  offered at a price equal to their net asset value plus a
sales charge which, at the option of the purchaser, may be imposed either at the
time of purchase (the  "initial  sales charge  alternative")  or on a contingent
deferred basis (the "deferred  sales charge  alternative").  Share  certificates
will not be issued unless requested by the shareholder in writing, and then only
will be issued for full  shares.  The  Trustees  reserve  the right to change or
waive the  Fund's  minimum  investment  requirements  and to reject any order to
purchase  shares  (including  purchase by exchange)  when in the judgment of the
Adviser such rejection is in the Fund's best interest.


The sales charges applicable to purchases of Class A and Class C shares of the
Fund are described in the Prospectus. Methods of obtaining a reduced sales
charges referred to generally in the Prospectus are described in detail below.
In calculating the sales charge applicable to current purchases of Class A
shares, the investor is entitled to accumulate current purchases with the
greater of the current value (at offering price) of the Class A shares of the
Fund, owned by the investor, or if John Hancock Signature Services, Inc.
("Signature Services") is notified by the investor's dealer or the investor at
the time of the purchase, the cost of the Class A shares owned.

charge or contingent  deferred sales charge ("CDSC") to various  individuals and

                  Merrill Lynch financial consultant for further information.

         o        Retirement plans investing through PruArray Program sponsored
                  by Prudential Securities.

         o        Pension plans transferring assets from a John Hancock variable
                  annuity   contract  to  the  Fund  pursuant  to  an  exemptive
                  application   approved   by  the   Securities   and   Exchange
                  Commission.



         o        Existing  full  service  clients of the Life  Company who were
                  group annuity  contract  holders as of September 1, 1994,  and
                  participant  directed  retirement  plans  with  at  least  100
                  eligible employees at the inception of the Fund account.  Each
                  of these investors may purchase Class A shares with no initial
                  sales charge.  However,  if the shares are redeemed  within 12
                  months  after  the  end of the  calendar  year  in  which  the
                  purchase  was made,  a CDSC will be imposed  at the  following
                  rate:

                     Amount Invested                           CDSC Rate
                     ---------------                           ---------

                     $1 to $4,999,999                            1.00%
                     Next $5 million to $9,999,999               0.50%
                     Amounts of $10 million and over             0.25%


Class C shares may be offered without a front-end sales charge to:

o             retirement  plans  for  which  John  Hancock  Signature   Services
              performs employer  sponsored plan recordkeeping  services.  (These
              types of plans include  401(k),  money  purchase  pension,  profit
              sharing and SIMPLE 401k.)

o             An investor who buys through a Merrill Lynch omnibus account.
              However, a CDSC may apply if the shares are sold within 12 months
              of purchase.

Class A and Class C shares may also be purchased without an initial sales charge
in  connection  with certain  liquidation,  merger or  acquisition  transactions
involving other investment companies or personal holding companies.


Combination Privilege. In calculating the sales charge applicable to purchases
of Class A shares made at one time, the purchases will be combined to reduce
sales charges if made by (a) an individual, his or her spouse and their children
under the age of 21, purchasing securities for his or their own account, (b) a
trustee or other fiduciary purchasing for a single trust, estate or fiduciary
account, and (c) groups which qualify for the Group Investment Program (see
below). A company's (not an individual's) qualified and non-qualified retirement
plan investments can be combined to take advantage of this privilege. Further
information about combined purchases, including certain restrictions on combined
group purchases, is available from Signature Services or a Selling Broker's
representative.

                                       36
<PAGE>


Accumulation Privilege.  Investors (including investors combining purchases) who
are  already  Class A  shareholders  may also  obtain the benefit of the reduced
sales charge by taking into account not only the amount being  invested but also
the investor's  purchase price or current account value of the Class A shares of
all John Hancock  funds which carry a sales charge  already held by such person.
Class A shares of John Hancock  money market funds will only be eligible for the
accumulation privilege if the investor has previously paid a sales charge on the
amount of those shares. Retirement plan investors may include the value of Class
B shares if Class B shares held are greater  than $1 million.  Retirement  plans
must notify  Signature  Services to utilize.  A company's (not an  individual's)
qualified and non-qualified  retirement plan investments can be combined to take
advantage of this privilege.

Group Investment Program. Under the Combination and Accumulation Privileges, all
members of a group may combine their  individual  purchases of Class A shares to
potentially  qualify for breakpoints in the sales charge schedule.  This feature
is  provided  to any  group  which (1) has been in  existence  for more than six
months,  (2) has a  legitimate  purpose  other than the  purchase of mutual fund
shares at a discount for its members,  (3) utilizes salary  deduction or similar
group methods of payment, and (4) agrees to allow sales materials of the fund in
its mailings to members at a reduced or no cost to John Hancock Funds.

Letter of Intention.  Reduced sales charges are also  applicable to  investments
pursuant to a Letter of Intention  (the "LOI"),  which should be read  carefully
prior to its execution by an investor. The Fund offers two options regarding the
specified  period for making  investments  under the LOI. All investors have the
option of  making  their  investments  over a period of  thirteen  (13)  months.
Investors  who are using the Fund as a funding  medium  for a  retirement  plan,
however, may opt to make the necessary  investments called for by the LOI over a
forty-eight (48) month period. These retirement plans include traditional,  Roth
and Education IRAs, SEP,  SARSEP,  401(k),  403(b)  (including TSAs) SIMPLE IRA,
SIMPLE 401(k), Money Purchase Pension,  Profit Sharing and Section 457 plans. An
individual's  non-qualified and qualified  retirement plan investments cannot be
combined  to  satisfy  an  LOI  of 48  months.  Such  an  investment  (including
accumulations  and  combinations  but not including  reinvested  dividends) must
aggregate  $100,000 or more during the specified period from the date of the LOI
or from a date within ninety (90) days prior  thereto,  upon written  request to
Signature  Services.  The sales charge  applicable to all amounts invested under
the LOI is computed as if the aggregate  amount intended to be invested had been
invested  immediately.  If such aggregate amount is not actually  invested,  the
difference in the sales charge  actually  paid and the sales charge  payable had
the LOI not been in effect is due from the investor.  However, for the purchases
actually made within the specified  period  (either 13 or 48 months),  the sales
charge  applicable  will not be  higher  than  that  which  would  have  applied
(including  accumulations  and  combinations)  had the LOI been  for the  amount
actually invested.

The LOI authorizes Signature Services to hold in escrow sufficient Class A
shares (approximately 5% of the aggregate) to make up any difference in sales
charges on the amount intended to be invested and the amount actually invested,
until such investment is completed within the specified period, at which time
the escrowed Class A shares will be released. If the total investment specified
in the LOI is not completed, the Class A shares held in escrow may be redeemed
and the proceeds used as required to pay such sales charge as may be due. By
signing the LOI, the investor authorizes Signature Services to act as his
attorney-in-fact to redeem any escrowed Class A shares and adjust the sales
charge, if necessary. A LOI does not constitute a binding commitment by an
investor to purchase, or by the subject Fund to sell, any additional Class A
shares and may be terminated at any time.

Deferred Sales Charge on Class B AND CLASS C  Shares


Investments in Class B shares are purchased at net asset value per share without
the imposition of an initial sales charge so that the Fund will receive the full
amount of the purchase payment.


Contingent Deferred Sales Charge.  Class B and Class C shares which are redeemed
within  six years or one year of  purchase,  respectively,  will be subject to a
CDSC at the rates set forth in the  Prospectus  as a  percentage  of the  dollar
amount  subject to the CDSC.  The charge will be assessed on an amount  equal to
the lesser of the current  market  value or the  original  purchase  cost of the
Class B or Class C shares being  redeemed.  No CDSC will be imposed on increases
in account  value above the initial  purchase  price or on shares  derived  from
reinvestment of dividends or capital gains distributions.

Class B shares are not available to full-service  retirement plans  administered
by  Signature  Services  or the Life  Company  that had more  than 100  eligible
employees at the inception of the Fund account.

The amount of the CDSC, if any, will vary  depending on the number of years from
the  time of  payment  for the  purchase  of Class B  shares  until  the time of
redemption  of such  shares.  Solely for purposes of  determining  the number of
years from the time of any payment for the  purchase of both Class B and Class C
shares,  all payments  during a month will be aggregated and deemed to have been
made on the first day of the month.

In determining  whether a CDSC applies to a redemption,  the calculation will be
determined in a manner that results in the lowest  possible rate being  charged.
It will be assumed  that your  redemption  comes first from shares you have held
beyond  the  six-year  CDSC  redemption  period  for  Class B or one  year  CDSC
redemption  period  for  Class C, or those you  acquired  through  dividend  and
capital  gain  reinvestment,  and next from the shares you have held the longest
during the six-year period for Class B shares.  For this purpose,  the amount of
any increase in a share's value above its initial  purchase price is not subject
to a CDSC.  Thus,  when a share that has appreciated in value is redeemed during
the CDSC period, a CDSC is assessed only on its initial purchase price.

When  requesting a redemption for a specific  dollar amount,  please indicate if
you require the proceeds to equal the dollar amount requested. If not indicated,
only the  specified  dollar  amount will be redeemed  from your  account and the
proceeds will be less any applicable CDSC.

Example:


You have purchased 100 Class B shares at $10 per share. The second year after
your purchase, your investment's net asset value per share has increased by $2
to $12, and you have gained 10 additional shares through dividend reinvestment.
If you redeem 50 shares at this time your CDSC will be calculated as follows:


   oProceeds of 50 shares redeemed at $12 per shares (50 x 12)          $600.00
   o*Minus Appreciation ($12 - $10) x 100 shares                        (200.00)
   o Minus proceeds of 10 shares not subject
     to CDSC (dividend reinvestment)                                    (120.00)
                                                                        -------
   oAmount subject to CDSC                                              $280.00

*The appreciation is based on all 100 shares in the account not just the shares
being redeemed.

                                       38

Proceeds  from the CDSC are paid to John Hancock  Funds and are used in whole or
in part by John  Hancock  Funds to defray  its  expenses  related  to  providing
distribution-related  services  to the Fund in  connection  with the sale of the
Class B and  Class C  shares,  such as the  payment  of  compensation  to select
Selling  Brokers for selling Class B and Class C shares.  The combination of the
CDSC and the  distribution  and service fees facilitates the ability of the Fund
to sell the Class B and Class C shares  without a sales charge being deducted at
the time of the purchase.

Waiver  of  Contingent  Deferred  Sales  Charge.  The  CDSC  will be  waived  on
redemptions of Class B and Class C shares and of Class A shares of the Fund that
are subject to a CDSC, unless indicated otherwise,  in the circumstances defined
below:

For all account types:

*        Redemptions made pursuant to the Fund's right to liquidate your account
         if you own shares worth less than $1,000.

         transactions  involving other investment  companies or personal holding

         not exceed 12% of your account value,  including reinvested  dividends,
         at the time you  established  your periodic  withdrawal plan and 12% of
         the value of subsequent  investments (less redemptions) in that account
         at the time you notify  Signature  Services.  (Please note, this waiver
         does not apply to periodic  withdrawal  plan  redemptions of Class A or
         Class C shares that are subject to a CDSC.)

*        Redemptions  by  Retirement   plans   participating  in  Merrill  Lynch

         beneficiaries from employer  sponsored  retirement plans under sections

If you qualify for a CDSC waiver under one of these situations,  you must notify
Signature  Services  at the time you make your  redemption.  The waiver  will be
granted  once  Signature  Services  has  confirmed  that you are entitled to the
waiver.

Special Redemptions

Although  it  would  not  normally  do so,  the  Fund  has the  right to pay the
redemption  price  of  shares  of the  Fund in  whole  or in  part in  portfolio
securities as prescribed by the Trustees.  When the shareholder  sells portfolio
securities  received in this  fashion,  the  shareholder  will incur a brokerage
charge.  Any such  securities  would be valued for the  purpose  of making  such
payment at the same value as used in determining the Fund's net asset value. The
Fund has,  however,  elected to be governed  by Rule 18f-1 under the  Investment
Company Act. Under that rule, the Fund must redeem its shares for cash except to
the extent that the  redemption  payments to any  shareholder  during any 90-day
period  would  exceed the lesser of $250,000 or 1% of the Fund's net asset value
at the beginning of such period.

Additional Services And Programs

Exchange Privilege.  The Fund permits exchanges of shares of any class of a fund
for shares of the same class in any other John Hancock fund offering that class.

Exchanges  between funds with shares that are not subject to a CDSC are based on
their  respective net asset values.  No sales charge or  transactions  charge is
imposed.  Shares of the Fund which are subject to a CDSC may be  exchanged  into
shares of any of the other John Hancock funds that are subject to a CDSC without
incurring the CDSC; however,  the shares acquired in an exchange will be subject
to the CDSC schedule of the shares acquired if and when such shares are redeemed
(except that shares  exchanged into John Hancock 500 Index Fund and John Hancock
Intermediate  Government  Fund will retain the exchanged  fund's CDSC schedule).
For purposes of computing the CDSC payable upon redemption of shares acquired in
an exchange,  the holding period of the original  shares is added to the holding
period of the shares acquired in an exchange.

If a shareholder exchanges Class B shares purchased prior to January 1, 1994 for
Class B shares of any other John Hancock fund, the acquired shares will continue
to be subject to the CDSC schedule that was in effect when the exchanged  shares
were purchased.

The Fund  reserves the right to require that  previously  exchanged  shares (and
reinvested  dividends)  be in the  Fund  for 90 days  before  a  shareholder  is
permitted a new exchange.

The Fund may refuse any exchange order. The Fund may change or cancel its
exchange policies at any time, upon 60 days' notice to its shareholders.

An exchange of shares is treated as a  redemption  of shares of one fund and the
purchase of shares of another for Federal  Income Tax purposes.  An exchange may
result in a taxable gain or loss. See "TAX STATUS".

Systematic Withdrawal Plan. The Fund permits the establishment of a Systematic
Withdrawal Plan. Payments under this plan represent proceeds arising from the
redemption of Fund shares, which may result in realization of gain or loss for
purposes of Federal, state and local income taxes. The maintenance of a
Systematic Withdrawal Plan concurrently with purchases of additional shares of
the Fund could be disadvantageous to a shareholder because of the initial sales
charge payable on such purchases of Class A shares and the CDSC imposed on
redemptions of Class B and Class C shares and because redemptions are taxable
events. Therefore, a shareholder should not purchase shares at the same time as
a Systematic Withdrawal Plan is in effect. The Fund reserves the right to modify
or discontinue the Systematic Withdrawal Plan of any shareholder on 30 days'
prior written notice to such shareholder, or to discontinue the availability of
such plan in the future. The shareholder may terminate the plan at any time by
giving proper notice to Signature Services.

Monthly Automatic Accumulation Program ("MAAP"). The program is explained in the
Prospectus. The program, as it relates to automatic investment checks, is
subject to the following conditions:

The investment will be drawn on or about the day of the month indicated.

The privilege of making investments through the MAAP may be revoked by Signature
Services  without  prior  notice  if  any  investment  is  not  honored  by  the
shareholder's  bank.  The  bank  shall  be under no  obligation  to  notify  the
shareholder as to the non-payment of any checks.

The program may be discontinued by the shareholder  either by calling  Signature
Services or upon written notice to Signature Services which is received at least
five (5) business days prior to the order date of any investment.

Reinstatement  and  Reinvestment  Privilege.  If Signature  Services is notified
prior to  reinvestment,  a shareholder  who has redeemed Fund shares may, within
120 days  after the date of  redemption,  reinvest  without  payment  of a sales
charge any part of the  redemption  proceeds in shares of the same class of that
Fund or another John Hancock fund,  subject to the minimum  investment  limit of
that fund.  The proceeds from the redemption of Class A shares may be reinvested
at net asset value  without  paying a sales charge in Class A shares of any John
Hancock fund. If a CDSC was paid upon a redemption,  a shareholder  may reinvest
the proceeds from this redemption at net asset value in additional shares of the
class from which the  redemption  was made.  The  shareholder's  account will be
credited with the amount of the CDSC charged upon the prior  redemption  and the
new shares will  continue to be subject to the CDSC.  The holding  period of the
shares acquired  through  reinvestment  will, for purposes of computing the CDSC
payable upon a subsequent redemption, include the holding period of the redeemed
shares.

To protect the interests of other investors in the Fund, the Fund may cancel the
reinvestment  privilege of any parties  that,  in the opinion of the Funds,  are
using market timing  strategies or making more than seven exchanges per owner or
controlling  party per calendar year. Also, the Fund may refuse any reinvestment
request.

The Fund may change or cancel its reinvestment policies at any time.

A  redemption  or exchange of Fund shares is a taxable  transaction  for Federal
income tax purposes even if the  reinvestment  privilege is  exercised,  and any
gain or loss realized by a shareholder on the redemption or other disposition of
Fund shares will be treated for tax purposes as described under the caption "TAX
STATUS."

Retirement Plans participating in Merrill Lynch's servicing programs.

Class A shares  are  available  at net asset  value for plans with $3 million in
plan assets or 500 eligible  employees  at the date the Plan  Sponsor  signs the
Merrill Lynch Recordkeeping Service Agreement.  If the plan does not meet either
of these limits, Class A shares are not available.

For  participating  retirement  plans  investing in Class B shares,  shares will
convert  to Class A shares  after  eight  years,  or sooner if the plan  attains
assets of $5 million (by means of a CDSC-free  redemption/purchase  at net asset
value).

PURCHASES AND REDEMPTIONS THROUGH THIRD PARTIES

Shares of the Fund may be purchased or redeemed through certain  broker-dealers.
Brokers  may charge for their  services  or place  limitations  on the extent to
which  you may use the  services  of the  Fund.  The Fund will be deemed to have
received  a  purchase  or  redemption  order when an  authorized  broker,  or if
applicable,  a broker's authorized designee,  receives the order. If a broker is
an  agent  or  designee  of the  Fund,  orders  are  processed  at the NAV  next
calculated  after the broker  receives the order.  The broker must segregate any
orders it  receives  after the close of  regular  trading  on the New York Stock
Exchange  and  transmit  those  orders  to the  Fund for  execution  at NAV next
determined.  Some brokers that maintain nominee accounts with the Fund for their
clients charge an annual fee on the average net assets held in such accounts for
accounting,  servicing,  and distribution  services they provide with respect to
the underlying Fund shares. The Adviser,  the Fund, and John Hancock Funds, Inc.
(the Fund's principal distributor), share in the expense of these fees.

Description Of The Fund's Shares

The Trustees of the Trust are  responsible for the management and supervision of
the Fund.  The  Declaration  of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of the Fund, without
par value.  Under the  Declaration of Trust,  the Trustees have the authority to
create and classify shares of beneficial interest in separate series and classes
without  further  action by  shareholders.  As of the date of this  Statement of
Additional Information,  the Trustees have authorized the issuance of two series
of shares - John Hancock Massachusetts Tax-Free Income Fund and the John Hancock
New York Tax-Free Income Fund. Additional series may be added in the future. The
Trustees  have also  authorized  the issuance of three classes of shares of each
series, designated as Class A, Class B and Class C.

The shares of each class of the Fund represent an equal  proportionate  interest
in the  aggregate net assets  attributable  to that class or series of the Fund.
Holders of each class of shares have certain  exclusive voting rights on matters
relating to their respective  distribution  plans. The different  classes of the
Fund may bear  different  expenses  relating to the cost of holding  shareholder
meetings necessitated by the exclusive voting rights of any class of shares.

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 on the same day and will be
in the same amount, except for differences resulting from the facts that (i) the
distribution  and  service  fees  relating to each class of shares will be borne
exclusively  by that  class  (ii)  Class B and  Class C shares  will pay  higher
distribution and service fees than Class A shares and (iii) each class of shares
will bear any class expenses properly allocable to that class of shares, subject
to the  conditions  the  Internal  Revenue  Service  imposes with respect to the
multiple-class  structures.  Similarly,  the net asset  value per share may vary
depending on which class of shares are  purchased.  No interest  will be paid on
uncashed dividend or redemption checks.

In the event of  liquidation,  shareholders  of each class are entitled to share
pro rata in the net  assets  of the Fund  available  for  distribution  to these
shareholders.  Shares  entitle their  holders to one vote per share,  are freely
transferable  and have no preemptive,  subscription or conversion  rights.  When
issued,  shares are fully  paid and  non-assessable  by the Fund,  except as set
forth below.

Unless otherwise required by the Investment Company Act or the Declaration of
Trust, the Fund has no intention of holding annual meetings of shareholders. The
Fund's shareholders may remove a Trustee by the affirmative vote of at least
two-thirds of the Fund's outstanding shares and the Trustees shall promptly call
a meeting for such purpose when requested to do so in writing by the record
holders of not less than 10% of the outstanding shares of the Fund. Shareholders
may, under certain circumstances, communicate with other shareholders in
connection with requesting a special meeting of shareholders. However, at any
time that less than a majority of the Trustees holding office were elected by
the shareholders, the Trustees will call a special meeting of shareholders for
the purpose of electing Trustees.

Under Massachusetts law,  shareholders of a Massachusetts  business trust could,
under certain  circumstances,  be held personally liable for acts or obligations
of the Trust.  However,  the Fund's  Declaration  of Trust  contains  an express
disclaimer  of  shareholder  liability for acts,  obligations  or affairs of the
Fund.  The  Declaration  of Trust also provides for  indemnification  out of the
Fund's  assets for all losses and expenses of any  shareholder  of any Fund held
personally  liable  by  reason  of  being  or  having  been a  shareholder.  The
Declaration  of Trust also  provides  that no series of the Fund shall be liable
for the liabilities of any other series.  Furthermore,  no fund included in this
Fund's  Prospectus shall be liable for the liabilities of any other John Hancock
fund.  Liability is therefore  limited to circumstances in which the Fund itself
would be unable to meet its obligations,  and the possibility of this occurrence
is remote.

The Fund reserves the right to reject any  application  which conflicts with the
Fund's  internal  policies or the  policies of any  regulatory  authority.  John
Hancock Funds does not accept  starter,  credit card or third party checks.  All
checks  returned by the post office as  undeliverable  will be reinvested at net
asset  value in the fund or funds from which a  redemption  was made or dividend
paid.  Information  provided on the account application may be used by the Funds
to verify the accuracy of the information or for background or financial history
purposes.  A joint account will be administered as a joint tenancy with right of
survivorship,  unless the joint owners notify Signature  Services of a different
intent.  A shareholder's  account is governed by the laws of The Commonwealth of
Massachusetts. For telephone transactions, the transfer agent will take measures
to verify the identity of the caller,  such as asking for name,  account number,
Social Security or other taxpayer ID number and other relevant  information.  If
appropriate  measures are taken,  the transfer agent is not  responsible for any
losses that may occur to any account due to an unauthorized telephone call. Also
for your protection  telephone  transactions are not permitted on accounts whose
names or addresses have changed within the past 30 days. Proceeds from telephone
transactions can only be mailed to the address of record.

Selling activities for the Fund may not take place outside the U.S. except with
U.S. military bases, APO addresses and U.S. diplomats. Brokers of record on
Non-U.S. investors' accounts with foreign mailing addresses are required to
certify that all sales activities have occurred, and in the future will occur,
only in the U.S. A foreign corporation may purchase shares of the Fund only if
it has a U.S. mailing address.

TAX STATUS

Federal Income Taxation

The Fund is treated as a separate  entity for accounting  and tax purposes,  has
qualified and elected to be treated as a "regulated  investment  company"  under
Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"),  and
intends to so qualify for each taxable year.  As such and by complying  with the
applicable  provisions  of the Code  regarding  the sources of its  income,  the
timing of its  distributions,  and the  diversification  of its assets, the Fund
will not be subject to Federal income tax on its tax-exempt interest and taxable
income   (including  net  realized   capital  gains)  which  is  distributed  to
shareholders in accordance with the timing requirements of the Code.

The Fund will be subject to a 4%  non-deductible  Federal  excise tax on certain
amounts not distributed (and not treated as having been distributed) on a timely
basis in accordance  with annual  minimum  distribution  requirements.  The Fund
intends under normal  circumstances  to seek to avoid or minimize  liability for
such tax by satisfying such distribution requirements.

                                       45
<PAGE>


The Fund expects to qualify to pay  "exempt-interest  dividends,"  as defined in
the Code.  To qualify to pay  exempt-interest  dividends,  the Fund must, at the
close of each quarter of its taxable year, have at least 50% of the value of its
total assets  invested in municipal  securities  whose interest is excluded from
gross  income  under  Section  103(a)  of  the  Code.  In  purchasing  municipal
securities,  the Fund intends to rely on opinions of nationally  recognized bond
counsel for each issue as to the  excludability  of interest on such obligations
from gross  income for  federal  income tax  purposes  and,  if  available,  the
exemption of such interest from New York State and New York City personal income
taxes.  The Fund will not undertake  independent  investigations  concerning the
tax-exempt status of such  obligations,  nor does it guarantee or represent that
bond counsels'  opinions are correct.  Bond counsels' opinions will generally be
based in part upon  covenants  by the  issuers  and  related  parties  regarding
continuing   compliance  with  federal  tax   requirements.   Tax  laws  enacted
principally  during the 1980's not only had the effect of limiting  the purposes
for which  tax-exempt  bonds  could be issued  and  reducing  the supply of such
bonds, but also increased the number and complexity of requirements that must be
satisfied on a continuing basis in order for bonds to be and remain  tax-exempt.
If the issuer of a bond or a user of a  bond-financed  facility  fails to comply
with such  requirements at any time,  interest on the bond could become taxable,
retroactive to the date the  obligation was issued.  In that event, a portion of
the Fund's distributions attributable to interest the Fund received on such bond
for  the  current   year  and  for  prior  years  could  be   characterized   or
recharacterized  as taxable income.  The availability of tax-exempt  obligations
and the value of the Fund's  portfolio  may be affected by  restrictive  federal
income tax legislation enacted in recent years or by similar future legislation.

If the Fund  satisfies the applicable  requirements,  dividends paid by the Fund
which are  attributable  to tax exempt  interest  on  municipal  securities  and
designated by the Fund as  exempt-interest  dividends in a written notice mailed
to its shareholders within sixty days after the close of its taxable year may be
treated by shareholders as items of interest  excludable from their gross income
under Section 103(a) of the Code. The recipient of tax-exempt income is required
to report such income on his federal income tax return.  However,  a shareholder
is advised to consult his tax adviser  with  respect to whether  exempt-interest
dividends retain the exclusion under Section 103(a) if such shareholder would be
treated as a  "substantial  user" or a "related  person"  thereof  under Section
147(a) with respect to any of the tax-exempt  obligations  held by the Fund. The
Code provides that interest on indebtedness incurred or continued to purchase or
carry shares of the Fund is not deductible to the extent it is deemed related to
the Fund's  exempt-interest  dividends.  Pursuant to published  guidelines,  the
Internal  Revenue  Service may deem  indebtedness  to have been incurred for the
purpose of  purchasing  or carrying  shares of the Fund even though the borrowed
money may not be directly traceable to the purchase of shares.

Although all or a substantial  portion of the dividends  paid by the Fund may be
excluded by the Fund's  shareholders  from their gross income for federal income
tax  purposes,  the Fund may purchase  specified  private  activity  bonds,  the
interest from which  (including the Fund's  distributions  attributable  to such
interest)  may be a  preference  item for  purposes of the  federal  alternative
minimum tax (both individual and corporate).  All exempt-interest dividends from
the Fund,  whether or not  attributable to private  activity bond interest,  may
increase a corporate shareholder's  liability, if any, for corporate alternative
minimum tax and will be taken into account in determining  the extent to which a
shareholder's  Social  Security  or certain  railroad  retirement  benefits  are
taxable.

Distributions other than exempt-interest dividends from the Fund's current or
accumulated earnings and profits ("E&P") will be taxable under the Code for
investors who are subject to tax. Taxable distributions include distributions
from the Fund that are attributable to (i) taxable income, including but not
limited to taxable bond interest, recognized market discount income, original

                                       46
<PAGE>


issue discount income accrued with respect to taxable bonds, income from
repurchase agreements, income from securities lending, income from dollar rolls,
income from interest rate swaps, caps, floors and collars, and a portion of the
discount from certain stripped tax- exempt obligations or their coupons or (ii)
capital gains from the sale or constructive sale of securities or other
investments (including from the disposition of rights to when-issued securities
prior to issuance) or from options and futures contracts. If these distributions
are paid from the Fund's "investment company taxable income," they will be
taxable as ordinary income; and if they are paid from the Fund's "net capital
gain," they will be taxable as long-term capital gain. (Net capital gain is the
excess (if any) of net long-term capital gain over net short-term capital loss,
and investment company taxable income is all taxable income and capital gains or
losses, other than those gains and losses included in computing net capital
gain, after reduction by deductible expenses.) Some distributions may be paid in
January but may be taxable to shareholders as if they had been received on
December 31 of the previous year. The tax treatment described above will apply
without regard to whether distributions are received in cash or reinvested in
additional shares of the Fund.

Distributions,  if any,  in excess of E&P will  constitute  a return of  capital
under the Code, which will first reduce an investor's  federal tax basis in Fund
shares and then, to the extent such basis is exceeded,  will generally give rise
to capital  gains.  Amounts  that are not  allowable as a deduction in computing
taxable income,  including expenses  associated with earning tax-exempt interest
income,  do not  reduce  the  Fund's  current  earnings  and  profits  for these
purposes.  Consequently,  the portion, if any, of the Fund's  distributions from
gross tax-exempt  interest income that exceeds its net tax-exempt interest would
be taxable as ordinary income to the extent of such  disallowed  deductions even
though  such  excess  portion  may  represent  an  economic  return of  capital.
Shareholders who have chosen automatic  reinvestment of their distributions will
have a federal tax basis in each share received  pursuant to such a reinvestment
equal to the amount of cash they would have received had they elected to receive
the  distribution  in cash,  divided  by the  number of shares  received  in the
reinvestment.

After the close of each calendar year, the Fund will inform  shareholders of the
federal  income tax status of its  dividends  and  distributions  for such year,
including the portion of such  dividends  that  qualifies as tax-exempt  and the
portion, if any, that should be treated as a tax preference item for purposes of
the federal  alternative  minimum tax.  Shareholders who have not held shares of
the Fund for its full taxable year may have designated as tax-exempt or as a tax
preference item a percentage of  distributions  which is not equal to the actual
amount of a pro rata share of tax-exempt  income or tax  preference  item income
earned by the Fund during the period of their investment in the Fund.

The amount of the Fund's net realized  capital gains,  if any, in any given year
will vary depending upon the Adviser's current  investment  strategy and whether
the  Adviser  believes  it to be in the best  interest of the Fund to dispose of
Fund  securities  and/or  engage in options or  futures  transactions  that will
generate  capital  gains.  At the time of an  investor's  purchase of the Fund's
shares,  a portion of the purchase  price is often  attributable  to realized or
unrealized  appreciation  in  the  Fund's  portfolio.  Consequently,  subsequent
distributions  on these  shares  from such  appreciation  may be taxable to such
investor even if the net asset value of the investor's shares is, as a result of
the  distributions,  reduced below the investor's cost for such shares,  and the
distributions in reality represent a return of a portion of the purchase price.

Upon a redemption or other disposition of shares of the Fund (including by
exercise of the exchange privilege) in a transaction that is treated as a sale
for tax purposes, a shareholder will ordinarily realize a taxable gain or loss
depending upon the amount of the proceeds and the investor's basis in his
shares. Such gain or loss will be treated as capital gain or loss if the shares
are capital assets in the shareholder's hands. A sales charge paid in purchasing
shares of the Fund cannot be taken into account for purposes of determining gain

                                       47
<PAGE>


or loss on the redemption or exchange of such shares within 90 days after their
purchase to the extent shares of the Fund or another John Hancock Fund are
subsequently acquired without payment of a sales charge pursuant to the
reinvestment or exchange privilege. This disregarded charge will result in an
increase in the shareholder's tax basis in the shares subsequently acquired.
Also, any loss realized on a redemption or exchange may be disallowed to the
extent the shares disposed of are replaced with other shares of the Fund within
a period of 61 days beginning 30 days before and ending 30 days after the shares
are disposed of, such as pursuant to automatic dividend reinvestments. In such a
case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss.

Any loss realized upon the redemption of shares with a tax holding period of six
months or less will be disallowed to the extent of all exempt-interest dividends
paid with  respect  to such  shares  and,  to the extent in excess of the amount
disallowed,  will be treated as a  long-term  capital  loss to the extent of any
amounts treated as distributions of long-term  capital gain with respect to such
shares.  Shareholders  should  consult  their own tax advisers  regarding  their
particular  circumstances  to determine  whether a disposition of Fund shares is
properly  treated as a sale for tax  purposes,  as is  assumed in the  foregoing
discussion.

Although its present  intention is to  distribute,  at least  annually,  all net
capital  gain, if any, the Fund reserves the right to retain and reinvest all or
any  portion of the excess of net  long-term  capital  gain over net  short-term
capital  loss in any year.  The Fund  will not,  in any  event,  distribute  net
capital  gain  realized in any year to the extent that a capital loss is carried
forward  from prior  years  against  such gain.  To the extent  such  excess was
retained and not exhausted by the  carryforward  of prior years' capital losses,
it would be subject to federal income tax in the hands of the Fund.  Upon proper
designation of this amount by the Fund,  each  shareholder  would be treated for
federal  income tax purposes as if the Fund had  distributed  to him on the last
day of its taxable year his pro rata share of such  excess,  and he had paid his
pro rata share of the taxes paid by the Fund and reinvested the remainder in the
Fund. Accordingly, each shareholder would (a) include his pro rata share of such
excess as long-term capital gain in his return for his taxable year in which the
last day of the Fund's  taxable  year  falls,  (b) be  entitled  either to a tax
credit on his  return  for,  or to a refund  of, his pro rata share of the taxes
paid by the Fund and (c) be entitled to increase  the adjusted tax basis for his
shares in the Fund by the  difference  between his pro rata share of such excess
and his pro rata share of such taxes.

For Federal  income tax  purposes,  the Fund is permitted to carry forward a net
capital loss in any year to offset its own net capital gains, if any, during the
eight years  following  the year of the loss. To the extent  subsequent  capital
gains are offset by such  losses,  they  would not result in federal  income tax
liability  to the  Fund  and,  as  noted  above,  would  not be  distributed  to
shareholders.  Presently,  there  are no  realized  capital  loss  carryforwards
available to offset future net realized capital gains.

The Fund is required to accrue  original issue discount  ("OID") on certain debt
securities (including zero coupon or deferred payment obligations) that have OID
prior to the receipt of the corresponding  cash payments.  The mark to market or
constructive  sale rules applicable to certain options and futures  contracts or
other transactions may also require the Fund to recognize income or gain without
a concurrent receipt of cash. However,  the Fund must distribute to shareholders
for each taxable year substantially all of its net income and net capital gains,
including such income or gain, to qualify as a regulated  investment company and
avoid  liability for any federal income or excise tax.  Therefore,  the Fund may
have to dispose of its portfolio securities under disadvantageous  circumstances
to  generate   cash,  or  borrow  the  cash,   to  satisfy  these   distribution
requirements.

The Federal income tax rules applicable to certain structured or indexed
securities, interest rate swaps, caps, floors and collars, dollar rolls and
possibly other investments or transactions, are unclear in certain respects, and
the Fund will account for these investments or transactions in a manner intended
to preserve its qualification as a regulated investment company and avoid
material tax liability.

                                       48

The Fund will be required to report to the Internal  Revenue Service (the "IRS")
all taxable  distributions to  shareholders,  as well as gross proceeds from the
redemption  or exchange  of Fund  shares,  except in the case of certain  exempt
recipients,  i.e.,  corporations  and certain other investors  distributions  to
which are exempt from the information  reporting  provisions of the Code.  Under
the backup withholding  provisions of Code Section 3406 and applicable  Treasury
regulations,  all such reportable  distributions  and proceeds may be subject to
backup  withholding  of  federal  income  tax at the  rate of 31% in the case of
non-exempt shareholders who fail to furnish the Fund with their correct taxpayer
identification number and certain  certifications  required by the IRS or if the
IRS or a broker  notifies the Fund that the number  furnished by the shareholder
is  incorrect  or that the  shareholder  is subject to backup  withholding  as a
result of failure to report  interest or dividend  income.  However,  the Fund's
taxable  distributions may not be subject to backup  withholding if the Fund can
reasonably  estimate that at least 95% of its distributions for the year will be
exempt-interest  dividends.  The Fund may refuse to accept an  application  that
does not contain any required  taxpayer  identification  number or certification
that the number provided is correct.  If the backup  withholding  provisions are
applicable,  any  such  distributions  and  proceeds,  whether  taken in cash or
reinvested  in shares,  will be reduced by the amounts  required to be withheld.
Any amounts withheld may be credited against a shareholder's U.S. federal income
tax   liability.   Investors   should  consult  their  tax  advisers  about  the
applicability of the backup withholding provisions.

The Fund may invest in debt obligations that are in the lower rating  categories
or are  unrated.  Investments  in debt  obligations  that are at risk of default
present  special tax issues for the Fund. Tax rules are not entirely clear about
issues  such as when the  Fund may  cease to  accrue  interest,  original  issue
discount,  or market discount,  when and to what extent  deductions may be taken
for bad debts or worthless  securities,  how payments received on obligations in
default should be allocated between principal and income,  and whether exchanges
of debt  obligations  in a workout  context are taxable.  If the Fund invests in
these debt obligations,  it will address these issues in order to seek to ensure
that it  distributes  sufficient  income to  preserve  its status as a regulated
investment company and seek to avoid Federal income or excise tax.

Dividends and capital gain  distributions  paid by the Fund will not qualify for
the dividends-received deduction for corporate shareholders.

Limitations imposed by the Code on regulated  investment companies like the Fund
may restrict the Fund's ability to enter into futures and options transactions.

Certain options and futures transactions undertaken by the Fund may cause the
Fund to recognize gains or losses from marking to market even though its
positions have not been sold or terminated and affect the character as long-term
or short-term and timing of some capital gains and losses realized by the Fund.
Additionally, the Fund may be required to recognize gain (subject to tax
distribution requirements) if an option, future, notional principal contract, or
a combination thereof is treated as a constructive sale of an appreciated
financial position in the Fund's portfolio. Also, certain of the Fund's losses
on its transactions involving options or futures contracts and/or offsetting or
successor Fund positions may be deferred rather than being taken into account
currently in calculating the Fund's taxable income or gains. Some of these
transactions may also cause the Fund to dispose of investments sooner than would
otherwise have occurred. These transactions may therefore affect the amount,
timing and character of the Fund's distributions to shareholders. The Fund will
take into account the special tax rules (including consideration of available
elections) applicable to options and futures transactions in order to seek to
minimize any potential adverse tax consequences.

The  foregoing  discussion  relates  solely to U.S.  Federal  income  tax law as
applicable to U.S. persons (i.e.,  U.S.  citizens or residents and U.S. domestic
corporations,  partnerships,  trusts or estates)  subject to tax under such law.
Dividends (including exempt-interest dividends), capital gain distributions, and
ownership of or gains realized on the redemption (including an exchange) of Fund
shares may also be subject to state and local taxes,  except as described  below
under "State Income Tax  Information."  The discussion  does not address special
tax rules applicable to certain types of investors,  such as insurance companies
and financial  institutions.  Shareholders should consult their own tax advisers
as to the Federal,  state or local tax  consequences  of ownership of shares of,
and receipt of distributions from, the Fund in their particular circumstances.

Non-U.S.  investors  not engaged in a U.S.  trade or  business  with which their
investment in the Fund is effectively  connected will be subject to U.S. Federal
income tax treatment different from that described above. These investors may be
subject to  non-resident  alien  withholding  tax at the rate of 30% (or a lower
rate under an applicable  tax treaty) on amounts  treated as ordinary  dividends
from the Fund  and,  unless an  effective  IRS Form  W-8,  Form  W-8BEN or other
authorized  withholding  certificate  is on file, to 31% backup  withholding  on
certain other payments from the Fund.  Non-U.S.  investors  should consult their
tax advisers regarding such treatment and the application of foreign taxes to an
investment in the Fund.

STATE INCOME TAX INFORMATION

The Fund is not subject to  Massachusetts  Corporate  excise or franchise taxes.
The Fund  anticipates  that,  provided  that the Fund  qualifies  as a regulated
investment  company  under the Code,  it will  also not be  required  to pay any
Massachusetts income tax.

NEW YORK TAXES

Exempt-interest  dividends derived from interest on tax-exempt bonds of New York
State  and  its  political   subdivisions  and  authorities  and  certain  other
governmental entities (for example, U.S.  possessions),  paid by the Fund to New
York resident individuals,  estates and trusts otherwise subject to these taxes,
will not be subject to New York State and New York City  personal  income  taxes
and certain municipal tax surcharges.

Dividends,  whether  received in cash or  additional  shares,  derived  from the
Fund's  other  investment   income  (including   interest  on  U.S.   Government
obligations  and  Tax-Exempt  Bonds other than those  described in the preceding
paragraph),  and from the Fund's net  realized  short-term  capital  gains,  are
taxable  for New York State and New York City  personal  income tax  purposes as
ordinary  income.  Tax surcharges  will also apply.  Dividends  derived from net
realized  long-term  capital gains of the Fund are taxable as long-term  capital
gains  for New York  State  and New  York  City  personal  income  tax  purposes
regardless of the length of time shareholders have held their shares.

Dividends  derived from investment  income and capital gains,  including exempt-
interest dividends,  will be subject to the New York State franchise tax and the
New York City General  Corporation  Tax if received by a corporation  subject to
those taxes. Certain  distributions may, however, be eligible for a 50% dividend
subtraction.  Shares of the Fund will be included  in a corporate  shareholder's
investment capital in determining its liability, if any, for these taxes.

New York State and New York City personal  income taxes are imposed on "New York
taxable income," which is defined, in the case of New York resident individuals,
estates  and  trusts  as "New York  adjusted  gross  income"  minus the New York
deductions and New York  exemptions.  "New York adjusted  gross income",  in the
case of a New York resident  individual,  estate or trust,  is federal  adjusted
gross income with certain  modifications  Because  distributions that qualify as
exempt-  interest  dividends  under IRC ss.  852(b)  (5) will be  excluded  from
Federal gross income and adjusted gross income,  such distributions will also be
excluded from New York adjusted gross income,  unless  specifically  modified by
New York law.

                                       50
<PAGE>


New York law requires that New York resident individuals, estates and trusts add
certain items to their federal adjusted gross income.  One such  modification is
the addition,  to the extent not properly  includible in Federal  adjusted gross
income, of interest income on obligations of any state (or political subdivision
of any state) other than New York and its political subdivisions.

The Fund's dividends  (including  exempt-interest  dividends) and  distributions
will not be tax-exempt for State and City purposes for corporate  investors,  so
that corporate  investors should consult their own tax advisers before investing
in the Fund. All investors  should consult their own tax advisers  regarding the
tax provisions  described  above and any  additional  taxes to which they may be
subject,  including but not limited to minimum taxes, tax surcharges,  and taxes
based on or affected by the ownership of intangible property such as mutual fund
shares.

Under New York tax law,  a portion  of  interest  on  indebtedness  incurred  or
continued to purchase or carry shares of an investment  company paying dividends
which are  exempt  from the New York  State and New York  City  personal  income
taxes,  such as the Fund,  will not be  deductible  by the investor for New York
State and New York City personal income tax purposes.

CALCULATION OF PERFORMANCE

For the 30-day  period  ended  August 31, 1999,  the  annualized  yields for the
Fund's  Class A,  Class B and  Class C  shares  were  4.63%,  4.13%  and  4.12%,
respectively.  The average annual total returns of the Fund's Class A shares for
the 1 year, 5 years and 10 years ended  August 31, 1999 were -5.50%,  3.95 % and
6.44%, respectively. The total returns for 1 year and since inception on October
3, 1996,  for Class B shares were -6.43 % and 3.40%,  respectively.  For Class C
shares,  for the period from April 1, 1999 to August 31, 1999, the average total
returns  were  -4.19%.  Class C  shares  commenced  operations  April  1,  1999;
therefore, there are no other periods to report.

The Fund may advertise yield, where appropriate. The Fund's yield is computed by
dividing net investment  income per share  determined for a 30-day period by the
maximum  offering price per share (which  includes the full sales charge) on the
last day of the period, according to the following standard formula:

                                               6
                  Yield = 2 ( [ ( a - b ) + 1 ] - 1 )
                                 -------
                                   cd
Where:

         a=       dividends and interest earned during the period.
         b=       net expenses accrued during the period.
         c=       the average daily number of fund shares outstanding during the
                  period that would be entitled to receive dividends.
         d=       the maximum offering price per share on the last day of the
                  period (NAV where applicable).

                                       51
<PAGE>


The Fund may  advertise a  tax-equivalent  yield,  which is computed by dividing
that portion of the yield of the Fund which is  tax-exempt by one minus a stated
income tax rate and adding the product to that portion,  if any, of the yield of
the Fund that is not tax-exempt.  The tax equivalent yields for the Fund's Class
A and Class B shares at the  combined  maximum  federal  and New York tax rates,
which assumes the full deductibility of state income taxes on the federal income
tax return,  for the 30-day  period  ended August 31, 1999 were 8.23% and 7.34%,
respectively.  The tax  equivalent  yield for the  Fund's  Class C shares at the
combined  maximum  federal  and New  York  tax  rates,  which  assume  the  full
deductibility  of state income taxes on the federal income tax equivalent  yield
for the period ended August 31, 1999 was 7.34%.

Total return is computed by finding the average annual compounded rate of return
over the 1 year,  5 year and  life-of-fund  period that would equate the initial
amount  invested  to the ending  redeemable  value  according  to the  following
formula:
                                n ______
                           T = \ / ERV/P - 1

Where:

P =      a hypothetical initial investment of $1,000.
T =      average annual total return.
n =      number of years.
ERV =    ending redeemable value of a hypothetical  $1,000 investment
         made at the beginning of the 1-year and life-of-fund periods.

Because each class has its own sales charge and fee structure,  the classes have
different  performance  results.  In the case of each  class,  this  calculation
assumes the maximum  sales charge is included in the initial  investment  or the
CDSC  applied  at the end of the  period.  This  calculation  assumes  that  all
dividends  and   distributions   are  reinvested  at  net  asset  value  on  the
reinvestment dates during the period.  The "distribution  rate" is determined by
annualizing the result of dividing the declared dividends of the Fund during the
period stated by the maximum offering price or net asset value at the end of the
period.  Excluding the Fund's sales charge from the distribution rate produces a
higher rate.

In addition to average  annual total returns,  the Fund may quote  unaveraged or
cumulative total returns  reflecting the simple change in value of an investment
over a stated period.  Cumulative total returns may be quoted as a percentage or
as a dollar amount, and may be calculated for a single  investment,  a series of
investments, and/or a series of redemptions, over any time period. Total returns
may be quoted with or without  taking the Fund's  sales charge on Class A shares
or the CDSC on Class B or Class C shares  into  account.  Excluding  the  Fund's
sales  charge on Class A shares and the CDSC on Class B or Class C shares from a
total return calculation produces a higher total return figure.

In the case of a tax-exempt  obligation  issued without  original issue discount
and having a current  market  discount,  the coupon  rate of interest is used in
lieu of the yield to maturity.  Where,  in the case of a  tax-exempt  obligation
with original  issue  discount,  the discount  based on the current market value
exceeds the then-remaining portion or original issue discount (market discount),
the yield to maturity is the imputed rate based on the original  issue  discount
calculation.  Where, in the case of a tax-exempt  obligation with original issue
discount,  the  discount  based on the  current  market  value is less  than the
then-remaining portion of original issue discount (market premium), the yield to
maturity is based on the market value.

                                       52
<PAGE>


From time to time, in reports and promotional  literature,  the Fund's yield and
total  return  will be  compared  to  indices of mutual  funds and bank  deposit
vehicles such as Lipper Analytical Services,  Inc.'s "Lipper - Fixed Income Fund
Performance  Analysis," a monthly  publication  which  tracks net assets,  total
return,  and yield on fixed income mutual funds in the United  States.  Ibottson
and Associates,  CDA  Weisenberger  and F.C. Towers are also used for comparison
purposes as well as the Russell and Wilshire  Indices.  Comparisons  may also be
made to bank certificates of deposit, ("CDs") which differ from mutual funds, in
several ways. The interest rate  established by the sponsoring bank is fixed for
the term of a CD, there are  penalties  for early  withdrawal  from CDs, and the
principal on a CD is insured.

Performance  rankings and ratings  reported  periodically in, and excerpts from,
national financial  publication such as MONEY MAGAZINE,  FORBES,  BUSINESS WEEK,
THE WALL STREET JOURNAL, MICROPAL, INC., MORNINGSTAR, STANGER'S, BARRON'S, etc.,
as well as  LIPPER,  may also be  utilized.  The  Fund's  promotional  and sales
literature may make reference to the Fund's "beta".  Beta is a reflection of the
market-related  risk of the Funds by showing how  responsive  the Fund is to the
market.

The performance of the Fund is not fixed or guaranteed.  Performance  quotations
should not be considered to be  representations  of  performance of the Fund for
any period in the  future.  The  performance  of the Fund is a function  of many
factors  including  its  earnings,  expenses and number of  outstanding  shares.
Fluctuating  market  conditions;  purchases,  sales and  maturities of portfolio
securities;  sales and redemptions of shares of beneficial interest; and changes
in  operating  expenses  are all examples of items that can increase or decrease
the Fund's performance.

Brokerage Allocation

Decisions  concerning  the  purchase and sale of  portfolio  securities  and the
allocation  of  brokerage  commissions  are  made  by the  Adviser  pursuant  to
recommendations made by an investment  committee of the Adviser,  which consists
of officers and  directors of the Adviser and  affiliates,  and Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner  which,  in the opinion of the  Adviser,  will offer the best
price and market for the  execution  of each such  transaction.  Purchases  from
underwriters  of portfolio  securities  may include a commission or  commissions
paid by the issuer  and  transactions  with  dealers  serving  as market  makers
reflect a "spread." Debt securities are generally  traded on a net basis through
dealers  acting  for their own  account as  principals  and not as  brokers;  no
brokerage commissions are payable on these transactions.

The Fund's  primary  policy is to execute all  purchases  and sales of portfolio
instruments  at the  most  favorable  prices  consistent  with  best  execution,
considering all of the costs of the transaction including brokerage commissions.
This policy governs the selection of brokers and dealers and the market in which
a transaction is executed.  Consistent with the foregoing  primary  policy,  the
Rules of Fair Practice of the National  Association of Securities Dealers,  Inc.
and such other policies as the Trustees may determine,  the Adviser may consider
sales of shares of the Fund as a factor in the  selection of  broker-dealers  to
execute the Fund's portfolio transactions.

To the extent consistent with the foregoing, the Fund will be governed in the
selection of brokers and dealers, and the negotiation of brokerage commission
rates and dealer spreads, by the reliability and quality of the services,
including primarily the availability and value of research information and to a
lesser extent statistical assistance furnished to the Adviser of the Fund, and
their value and expected contribution to the performance of the Fund. It is not
possible to place a dollar value on information and services to be received from
brokers and dealers, since it is only supplementary to the research efforts of
the Adviser. The receipt of research information is not expected to reduce
significantly the expenses of the Adviser. The research information and
statistical assistance furnished by brokers and dealers may benefit the Life

                                       53
<PAGE>


Company or other advisory clients of the Adviser, and, conversely, brokerage
commissions and spreads paid by other advisory clients of the Adviser may result
in research information and statistical assistance beneficial to the Fund. The
Fund will make no commitment to allocate portfolio transactions upon any
prescribed basis. While the Adviser's officers will be primarily responsible for
the allocation of the Fund's brokerage business, the policies in this regard
must be consistent with the foregoing and will at all times be subject to review
by the Trustees. For the years ended August 31, 1997, 1998 and 1999, the Fund
paid negotiated brokerage commissions in the amount of $13,877, $3,140 and
$6,904, respectively.

As permitted by Section 28(e) of the Securities  Exchange Act of 1934, the Funds
may pay to a broker which provides  brokerage and research  services to the Fund
an amount of disclosed  commission  in excess of the  commission  which  another
broker would have  charged for  effecting  that  transaction.  This  practice is
subject  to a good  faith  determination  by the  Trustees  that  the  price  is
reasonable  in light of the services  provided and to policies that the Trustees
may adopt from time to time.  During the fiscal years ended August 31, 1999, the
Fund  did not pay  commissions  as  compensation  to any  brokers  for  research
services  such as industry,  economic  and company  reviews and  evaluations  of
securities.

The  Adviser's  indirect  parent,  the  Life  Company,   is  the  indirect  sole
shareholder of Signator Investors, Inc., a broker-dealer (until January 1, 1999,
John Hancock Distributors, Inc.) ("Signator" or Affiliated Broker"). Pursuant to
procedures  determined by the Trustees and  consistent  with the above policy of
obtaining best net results, the Fund may execute portfolio  transactions with or
through the Affiliated Broker. During the year sending August 31, 1997, 1998 and
1999,  the Fund did not execute any portfolio  transactions  with the Affiliated
Broker.

Signator  may act as broker  for the Funds on  exchange  transactions,  subject,
however,  to the general  policy of the Funds set forth above and the procedures
adopted by the Trustees pursuant to the Investment Company Act. Commissions paid
to an  Affiliated  Broker  must be at least as  favorable  as  those  which  the
Trustees believe to be contemporaneously  charged by other brokers in connection
with comparable  transactions  involving  similar  securities being purchased or
sold. A transaction  would not be placed with an  Affiliated  Broker if the Fund
would have to pay a commission rate less favorable than the Affiliated  Broker's
contemporaneous  charges for comparable transactions for its other most favored,
but unaffiliated customers,  except for accounts for which the Affiliated Broker
acts as clearing  broker for another  brokerage  firm,  and any customers of the
Affiliated  Broker not comparable to the Fund as determined by a majority of the
Trustees who are not interested  persons (as defined in the  Investment  Company
Act) of the Fund,  the Adviser or the  Affiliated  Broker.  Because the Adviser,
which is affiliated with the Affiliated Broker, has, as an investment adviser to
the Fund,  the  obligation  to provide  investment  management  services,  which
include elements of research and related  investment  skills,  such research and
related  skills  will  not be  used by the  Affiliated  Broker  as a  basis  for
negotiating commissions at a rate higher than that determined in accordance with
the above criteria.

Other investment  advisory clients advised by the Adviser may also invest in the
same  securities as the Fund. When these clients buy or sell the same securities
at  substantially  the same time, the Adviser may average the  transaction as to
price and  allocate the amount of  available  investments  in a manner which the
Adviser believes to be equitable to each client,  including the Fund. Because of
this,  client  accounts in a particular  style may sometimes not sell or acquire
securities  as quickly or at the same prices as they might if each were  managed
and traded individually.

For purchases of equity securities, when a complete order is not filled, a
partial allocation will be made to each account pro rata based on the order
size. For high demand issues (for example, initial public offerings), shares
will be allocated pro rata by account size as well as on the basis of account
objective, account size ( a small account's allocation may be increased to
provide it with a meaningful position), and the account's other holdings. In
addition, an account's allocation may be increased if that account's portfolio

                                       54
<PAGE>


manager was responsible for generating the investment idea or the portfolio
manager intends to buy more shares in the secondary market. For fixed income
accounts, generally securities will be allocated when appropriate among accounts
based on account size, except if the accounts have different objectives or if an
account is too small to get a meaningful allocation. For new issues, when a
complete order is not filled, a partial allocation will be made to each account
pro rata based on the order size. However, if a partial allocation is too small
to be meaningful, it may be reallocated based on such factors as account
objectives, duration benchmarks and credit and sector exposure. In some
instances, this investment procedure may adversely affect the price paid or
received by the Fund or the size of the position obtainable for it. On the other
hand, to the extent permitted by law, the Adviser may aggregate securities to be
sold or purchased for the Fund with those to be sold or purchased for other
clients managed by it in order to obtain best execution.

Transfer Agent Services

John Hancock Signature  Services,  Inc., 1 John Hancock Way, Suite 1000, Boston,
MA 02217-1000,  a wholly-owned  indirect  subsidiary of the Life Company, is the
transfer  and  dividend  paying  agent for the  Funds.  The Fund pays  Signature
Services an annual fee of $20.00 for each Class A  shareholder  account,  $22.50
for each Class B  shareholder  account  and $21.50 for each Class C  shareholder
account.  The Fund also pays certain  out-of-pocket  expenses and these expenses
are  aggregated and charged to the Fund on the basis of their relative net asset
values.

Custody Of Portfolio

Portfolio  securities  of the Funds are held  pursuant to a custodian  agreement
between the Funds and Investors  Bank & Trust  Company,  200  Clarendon  Street,
Boston, MA 02116. Under the custodian agreement,  Investors Bank & Trust Company
performs custody, portfolio and fund accounting services.

Independent ACCOUNTANTs

The  independent  accountants  of the Fund are  PricewaterhouseCoopers  LLP, 160
Federal Street, Boston,  Massachusetts 02110.  PricewaterhouseCoopers LLP audits
and renders an opinion on the Fund's annual financial statements and reviews the
Fund's annual Federal income tax return.

APPENDIX A

MORE ABOUT RISK

A fund's risk profile is largely  defined by the fund's  primary  securities and
investment  practices.  You may find the most concise  description of the fund's
risk profile in the prospectus.

A fund is permitted to utilize -- within limits  established  by the trustees --
certain other  securities  and  investment  practices that have higher risks and
opportunities  associated  with them. To the extent that the Fund utilizes these
securities  or  practices,  its  overall  performance  may be  affected,  either
positively  or  negatively.  On the  following  pages are brief  definitions  of
certain  associated  risks with them with  examples  of related  securities  and
investment  practices  included in brackets.  See the "Investment  Objective and
Policies" and "Investment Restrictions" sections of this Statement of Additional
Information  for a  description  of this Fund's  investment  policies.  The Fund
follows certain policies that may reduce these risks.

As with any mutual fund, there is no guarantee that the Fund will earn income or
show a positive return over any period of time -- days, months or years.

TYPES OF INVESTMENT RISK

Correlation risk The risk that changes in the value of a hedging instrument will
not match those of the asset being hedged  (hedging is the use of one investment
to offset the effects of another investment).  Incomplete correlation can result
in unanticipated risks. (e.g., futures and related options; securities and index
options, swaps, caps, floors, collars).

Credit risk The risk that the issuer of a  security,  or the  counterparty  to a
contract,  will  default  or  otherwise  become  unable  to  honor  a  financial
obligation.  Common to all debt securities.(e.g.  borrowing;  reverse repurchase
agreements, repurchase agreements, financial futures and options; securities and
index options, securities lending, non-investment grade debt securities, private
activity bonds, participation interests and structured securities,  swaps, caps,
floors, collars).

Information risk The risk that key information about a security or market is
inaccurate or unavailable. Common to all municipal securities. (e.g.
non-investment grade debt securities, private activity bonds and participation
interests).

Interest rate risk The risk of market losses attributable to changes in interest
rates. With fixed-rate  securities,  a rise in interest rates typically causes a
fall in values,  while a fall in rates typically causes a rise in values.  (e.g.
financial  futures and options;  securities  and index  options,  non-investment
grade  debt  securities,   private  activity  bonds,   participation  interests,
structured securities and swaps, caps, floors and collars).

Leverage risk  Associated  with securities or practices (such as borrowing) that
multiply  small index or market  movements  into large  changes in value.  (e.g.
borrowing;  reverse repurchase  agreements,  when-issued  securities and forward
commitments).

o    Hedged  When a  derivative  (a  security  whose  value is based on  another
     security or index) is used as a hedge against an opposite position that the
     fund  also  holds,   any  loss  generated  by  the  derivative   should  be
     substantially  offset by gains on the hedged  investment,  and vice  versa.
     While  hedging  can  reduce  or  eliminate  losses,  it can also  reduce or
     eliminate gains.

                                      A-1
<PAGE>


o    Speculative  To the extent that a  derivative  is not used as a hedge,  the
     fund is directly exposed to the risks of that  derivative.  Gains or losses
     from  speculative  positions in a derivative may be  substantially  greater
     than the derivative's original cost.

o    Liquidity  risk  The risk  that  certain  securities  may be  difficult  or
     impossible  to sell at the time and the price that the seller  would  like.
     The seller may have to lower the price, sell other securities  instead,  or
     forego an investment opportunity, any of which could have a negative effect
     on fund management or  performance.  (e.g.  financial  futures and options;
     securities  and  index  options,   non-investment-grade   debt  securities,
     restricted and illiquid securities,  participation interests,  swaps, caps,
     floors, collars , structured securities).

Management risk The risk that a strategy used by a fund's management may fail to
produce the intended result. Common to all mutual funds.

Market risk The risk that the market  value of a security  may move up and down,
sometimes rapidly and unpredictably.  These fluctuations may cause a security to
be worth less than the price  originally  paid for it, or less than it was worth
at an earlier time. Market risk may affect a single issuer, industry,  sector of
the  economy  or the  market as a whole.  Common to all stocks and bonds and the
mutual  funds  that  invest  in  them.  (e.g.  financial  futures  and  options;
securities and index options,  short-term  trading,  when-issued  securities and
forward  commitments,   non-investment-grade  debt  securities,  restricted  and
illiquid securities, structured securities).

Natural event risk The risk of losses attributable to natural disasters, such as
earthquakes and similar events. (e.g. private activity bonds).

Opportunity  risk The risk of missing out on an investment  opportunity  because
the assets  necessary to take  advantage of it are tied up in less  advantageous
investments.  (e.g. financial futures and options; securities and index options,
when-issued securities and forward commitments).

Political risk The risk of losses attributable to government or political
actions of any sort. (e.g. private activity bonds).

Valuation  risk The risk that a fund has valued  certain of its  securities at a
higher  price  than  it  can  sell  them  for.(e.g.   non-investment-grade  debt
securities,   Restricted  and  illiquid  securities,   participation  interests,
structured securities, swaps, caps, floors, collars).

APPENDIX B
Ratings

Moody's describes its ratings for Tax-Exempt Bonds as follows:

Bonds.  "Bonds which are rated 'Aaa' are judged to be of the best quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
'gilt edge.' Interest  payments are protected by a large or by an  exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

"Bonds which are rated 'Aa' are judged to be of high  quality by all  standards.
Together with the 'Aaa' group they  comprise  what are  generally  known as high
grade  bonds.  They are rated  lower  than the best  bonds  because  margins  of
protection  may  not be as  large  as in  'Aaa'  securities  or  fluctuation  of
protective  elements may be of grater  amplitude or there may be other  elements
present  which make the long term risks  appear  somewhat  larger  than in 'Aaa'
securities.

"Bonds which are rated 'A' possess many favorable investment  attributes and are
to be considered as upper medium grade  obligations.  Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

"Bonds which are rated 'Baa' are considered as medium grade  obligations,  i.e.,
they are neither  highly  protected nor poorly  secured.  Interest  payments and
principal  security  appear  adequate  for the present  but  certain  protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding  investment  characteristics  and in
fact have speculative characteristics as well.

"Bonds  which are rated  'Ba' are  judged to have  speculative  elements;  their
future cannot be considered  as well assured.  Often the  protection of interest
and  principal  payments may be very  moderate and thereby not well  safeguarded
during  both  good and bad  times  over the  future.  Uncertainty  of  position,
characterizes bonds in this class.

"Bonds  which are rated 'B'  generally  lack  characteristics  of the  desirable
investment.  Assurance of interest and principal  payments or of  maintenance of
other terms of the contract over any long period of time may be small.

"Bonds which are rated 'Caa' are of poor standing. Such issues may be in default
or there may be  present  elements  of  danger  with  respect  to  principal  or
interest.

"Bonds which are rated 'Ca'  represent  obligations  which are  speculative in a
high degree. Such issues are often in default or have other marked shortcomings.

"Bonds which are rated 'C' are the lowest rated classes of bonds,  and issues so
rated can be regarded as having  extremely  poor prospects of ever obtaining any
real investment standing."

Where no  rating  has been  assigned  or where a rating  has been  suspended  or
withdrawn,  it may be for reasons unrelated to the quality of the issue.  Should
no  rating  be  assigned,  the  reason  may  be one  of  the  following:  (i) an
application  for rating was not received or  accepted;  (ii) the issue or issuer
belongs to a group of securities that are not rated as a matter of policy; (iii)
there is a lack of essential data pertaining to the issue or issuer; or (iv) the
issue was privately placed, in which case the rating is not published in Moody's
publications.

                                      B-1

Suspension or withdrawal may occur if new and material  circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable  up-to-date  data to permit a  judgment  to be  formed;  if a bond is
called for redemption; or for other reasons.

Standard & Poor's describes its ratings for Tax-Exempt Bonds as follows:

"AAA. Debt rated 'AAA' has the highest rating by Standard & Poor's. Capacity to
pay interest and repay principal is extremely strong.

"AA. Debt rated 'AA' has a very strong capacity to pay interest and repay
principal and differs from the higher rated issues only in small degree.

"A. Debt rated 'A' has a strong  capacity to pay  interest  and repay  principal
although it is somewhat more  susceptible  to the adverse  effects of changes in
circumstances and economic conditions than debt in higher rated categories.

"BBB. Debt rated 'BBB' is regarded as having  adequate  capacity to pay interest
and  repay  principal.   Whereas  it  normally  exhibits   adequate   protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
debt in this category than in higher rated categories."

Debt rated "BB," "B," "CCC," or "CC" is regarded,  on balance,  as predominantly
speculative  with  respect to the  issuer's  capacity  to pay  interest  and pay
principal in accordance  with the terms of the  obligation.  "BB"  indicates the
lowest degree of speculation and "CC" the highest degree of  speculation.  While
such debt will likely have some quality and  protective  characteristics,  these
may be  outweighed  by large  uncertainties  or major risk  exposures to adverse
conditions.

Unrated.  This  indicates  that no  rating  has been  requested,  that  there is
insufficient  information  on which to base a rating,  or that Standard & Poor's
does not rate a particular type of obligation as a matter of policy.

Fitch describes its rating for Tax-Exempt Bonds as follows:

         AAA. Bonds considered to be investment grade and of the highest credit
quality. The obligor has an exceptionally strong ability to pay interest and
repay principal, which is unlikely to be affected by reasonably foreseeable
events.

         AA. Bonds  considered  to be  investment  grade and of very high credit
quality.  The  obligor's  ability to pay  interest  and repay  principal is very
strong,  although not quite as strong as bonds rated "AAA".  Because bonds rated
in the  "AAA"  and the  'AA'  categories  are not  significantly  vulnerable  to
foreseeable future  developments,  short-term debt of these issuers is generally
rated 'F-1+'.

         A. Bonds  considered to be investment grade and of high credit quality.
The  obligor's  ability to pay interest and repay  principal is considered to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

         BBB. Bonds considered to be investment grade and of satisfactory credit
quality. The obligor's ability to pay interest and repay principal is considered
to be  adequate.  Adverse  changes in  economic  conditions  and  circumstances,
however,  are more likely to have adverse impact on these bonds,  and therefore,
impair timely payment.  The likelihood that the ratings of these bonds will fall
below investment grade is higher than for bonds with higher ratings.

                                      B-2
<PAGE>


         BB. Bonds are  considered  speculative.  The  obligor's  ability to pay
interest  and repay  principal  may be  affected  over time by adverse  economic
changes.  However,  business and financial  alternatives can be identified which
could assist the obligor in satisfying its debt service requirements.

Notes.  Ratings for state and municipal notes and other  short-term  obligations
will be designated  Moody's  Investment  Grade ("MIG").  This  distinction is in
recognition  of the  differences  between  short-term  credit risk and long-term
risk.  Factors  affecting  the  liquidity  of  the  borrower  are  uppermost  in
importance  in  short-term  borrowing,   while  various  factors  of  the  first
importance on bond risk are of lesser importance in the short run.
Symbols will be used as follows:

"MIG-1 Notes bearing this  designation are of the best quality,  enjoying strong
protection  from  established  cash flows of funds for their  servicing  or from
established and broad-based access to the market for refinancing, or both.

"MIG-2  Notes  bearing  this  designation  are of high  quality  with margins of
protection ample although not so large as in the preceding group."

Commercial  Paper.  As  described  in the  Prospectus,  the Fund may  invest  in
commercial  paper which is rated A-1 or A-2 by Standard & Poor's,  P-1 or P-2 by
Moody's or F-1+ or f1 by Fitch.

Moody's  ratings for commercial  paper are opinions of the ability of issuers to
repay  punctually  promissory  obligations  not having an  original  maturity in
excess of nine months.  Moody's two highest  commercial paper rating  categories
are as follows:

"P-1 -- "Prime-1"  indicates the highest quality repayment capacity of the rated
issues.

"P-2 -- "Prime-2"  indicates that the issuer has a strong capacity for repayment
of short-term promissory obligations. Earnings trends and coverage ratios, while
sound,  will be more  subjective to variation.  Capitalization  characteristics,
while still  appropriate,  may be more  affected by external  conditions.  Ample
alternate liquidity is maintained."

Standard & Poor's  commercial  paper  ratings  are  current  assessments  of the
likelihood  of timely  payment of debts  having an original  maturity of no more
than 365 days.  Standard & Poor's two highest commercial paper rating categories
are as follows:

"A-1 -- This  designation  indicates that the degree of safety  regarding timely
payment is very strong.  Those issues determined to possess  overwhelming safety
characteristics will be denoted with a plus (+) sign designation.

"A-2 -- Capacity for timely payment on issues with this designation is strong.
However, the relative degree of safety is not as high as for issues designated
A-1."

Fitch's  short-term ratings apply to debt obligations that are payable on demand
or have original maturities of generally up to three years, including commercial
paper,  certificates  of deposit,  medium notes,  and  municipal and  investment
notes.

The  short-term  rating places greater  emphasis than a long-term  rating on the
existence of liquidity  necessary to meet the issuer's  obligations  in a timely
manner.

Fitch's short-term ratings are as follows:

                                      B-3
<PAGE>


F-1+ Exceptionally strong Credit Quality. Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

F-1 Very Strong Credit Quality. Issues assigned this rating reflect an assurance
of timely payment only slightly less in degree than issues rated "F-1+"
