Overview

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

JOHN HANCOCK TAX-FREE INCOME FUNDS

John Hancock tax-free income 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 endorsed by any bank,
government agency or the FDIC. 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 Mutual Life Insurance Company and manages more than $30 billion in
assets.

California Tax-Free Income Fund

GOAL AND STRATEGY

[Clipart] 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. Although most
of these securities are investment grade when purchased, the fund may invest up
to 20% of assets in junk bonds rated BB/Ba and their unrated equivalents.

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

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

The fund may use certain derivatives (investments whose value is based on
indices or other securities), especially in managing its exposure to interest
rate risk, although it does not intend to use them extensively.

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

PAST PERFORMANCE

[Clipart] 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 and potential rewards. 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

[Clipart] The major factor in this fund's performance is interest rates. When
interest rates change, bond prices change in proportion to their duration.
Generally, a 1% rise in interest rates will cause a 1 % fall in value for every
year of an income fund's duration. If the fund's duration is longer than that of
the markets it invests in, it could suffer disproportionate losses when interest
rates rise.

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. If certain sectors or investments don't perform as the fund
expects, it could underperform 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     In a down market, certain securities could become harder to value or to
      sell at a fair price.

o     Certain derivatives could produce disproportionate gains or losses.

High Yield Tax-Free Fund


GOAL AND STRATEGY

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

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

The fund may use certain derivatives (investments whose value is based on
indices or other securities), especially in managing its exposure to interest
rate risk, although it does not intend to use them extensively.

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

MAIN RISKS

[Clipart] The major factors in this fund's performance are interest rates and
credit risk. When interest rates change, bond prices change in proportion to
their duration. Generally, a 1% rise in interest rates will cause a 1% fall in
value for every year of an income fund's duration. If the fund's duration is
longer than that of the markets it invests in, it could suffer disproportionate
losses when interest rates rise.

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 don't 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     In a down market, certain securities could become harder to value or to
      sell at a fair price.

o     Certain derivatives could produce disproportionate gains or losses.

Massachusetts Tax-Free Income Fund

GOAL AND STRATEGY

[Clipart] 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
Massachusetts municipal debt obligations of any maturity. 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 BBB/Baa or BB/Ba and their
unrated equivalents. Bonds that are in or below the BB/Ba category are
considered junk bonds.

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

The fund commonly seeks out revenue bonds, which are repaid from income tied to
specific facilities such as a power plant. The fund also favors bonds with
limitations on whether they can be called or redeemed by the issuer before
maturity. This enables the fund 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 use certain derivatives (investments whose value is based on
indices or other securities), especially in managing its exposure to interest
rate risk, although it does not intend to use them extensively.

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

PAST PERFORMANCE

[Clipart] 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 and potential rewards. 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.

In managing its portfolio, the fund uses top-down research to assess general
credit trends and identify promising market sectors. To select securities for
long-term investment, the fund uses a strategy designed to find undervalued
bonds, based on research into specific municipal issuers, their creditworthiness
and the structure of their bonds. The fund commonly seeks out revenue bonds,
which are repaid from income tied to specific facilities such as a power plant.
The fund may invest up to 25% of assets in private activity bonds.

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

The fund may use certain derivatives (investments whose value is based on
indices or other securities), especially in managing its exposure to interest
rate risk, although it does not intend to use them extensively.

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

PAST PERFORMANCE

[Clipart] 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 and potential rewards. The average annual figures reflect sales
charges; the year-to-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

[Clipart] The major factors in this fund's performance are interest rates and
credit risk. When interest rates change, bond prices change in proportion to
their duration. Generally, a 1% rise in interest rates will cause a 1% fall in
value for every year of an income fund's duration. If the fund's duration is
longer than that of the markets it invests in, it could suffer disproportionate
losses when interest rates rise.

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 don't 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     In a down market, certain securities could become harder to value or to
      sell at a fair price.

o     Certain derivatives could produce disproportionate gains or losses.

YOUR EXPENSES

[Clipart] 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, allowing you to choose the one that
best meets your requirements. Your financial representative can help you decide.

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

o     Front-end sales charges, as described below.

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.

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, Class B shareholders could end
up paying more expenses over the long term than if they had paid a sales charge.

- --------------------------------------------------------------------------------
HOW SALES CHARGES ARE CALCULATED

Class A  Sales charges are as follows:

- --------------------------------------------------------------------------------
Sales charges
- --------------------------------------------------------------------------------
                             As a % of                         As a % of your

$1,000,000 and over          See below

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

- --------------------------------------------------------------------------------
CDSC on $1 million+ investments
- --------------------------------------------------------------------------------
                                                               CDSC on shares

- --------------------------------------------------------------------------------
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 last 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. However, you may be charged a contingent deferred sales
charge (CDSC) on shares you sell within a certain time after you bought them, as
described in the table 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:

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

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.

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


14 YOUR ACCOUNT
<PAGE>

      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, no 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
o     to purchase a John Hancock Declaration annuity

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 insurance company contract holders (one-year CDSC usually applies)
o     participants in certain retirement plans with at least 100 eligible
      employees (one-year CDSC applies)

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, as 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 your request is accepted by
Signature Services.

At times of peak activity, it may be difficult to place requests by phone.
During these times, consider using EASI-Line 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
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 shares
will continue to age from the original date and will retain the same CDSC rate
as they had before the exchange, except that the rate will change to the new
fund's rate if that rate is higher. 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- and long-term capital gains are taxable. 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 generally will 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.

Year 2000 compliance  The adviser and the funds' service providers are taking
steps to address any year 2000-related computer problems. However, there is some
risk that these problems could disrupt the funds' operations or financial
markets generally.

- --------------------------------------------------------------------------------
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 accou nt 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.

BUSINESS STRUCTURE

The diagram below shows the basic business structure used by the John Hancock
tax-free income funds. Each fund's board of trustees oversees the fund's
business activities and retains the services of the various firms that carry out
the fund's operations.

The trustees of the Massachusetts Tax-Free Income and New York Tax-Free Income
funds have power to change these funds' respective investment goals without
shareholder approval.

Management fees  The management fees paid to the investment adviser by the John
Hancock tax-free income funds last year are as follows:

ORGANIZATION OF THE FUND

The Fund is a series of the Trust, an open-end investment  management investment
company  organized  as a  Massachusetts  business  trust  under  the laws of The
Commonwealth  of  Massachusetts.  Prior to September  30,  1996,  the Fund was a
series of John Hancock Series, Inc.
    

John Hancock Advisers,  Inc. (the "Adviser") is the Fund's  investment  adviser.
The Adviser is an indirect,  wholly owned subsidiary of 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.

INVESTMENT OBJECTIVE AND POLICIES

   
The following  information  supplements the discussion of the Fund's  investment
objective  discussed in the Prospectus.  Appendix A contains further information
describing  investment  risks.  The investment  objective is fundamental and may
only be changed with shareholder  approval.  There is no assurance that the Fund
will achieve its investment objective.

The Fund's  primary  investment  objective  is to obtain a high level of current
income that is largely exempt from federal  income taxes and is consistent  with
the  preservation  of  capital.  The Fund  pursues  this  objective  by normally
investing   substantially  all  of  its  assets  in  medium  and  lower  quality
obligations, including bonds, notes and commercial paper, issued by or on behalf
of states,  territories  and  possessions of the United States,  the District of
Columbia and their political  subdivisions,  agencies or instrumentalities,  the
interest on which is exempt from federal income tax  ("tax-exempt  securities").
The Fund seeks as its secondary objective  preservation of capital by purchasing
and selling interest rate futures contracts ("financial futures") and tax-exempt
bond index futures  contracts ("index  futures"),  and by purchasing and writing
put and call options on debt  securities,  financial  futures,  tax-exempt  bond
indices  and index  futures to hedge  against  changes in the  general  level of
interest rates.

As a fundamental policy, the Fund invests, in normal circumstances, at least 80%
of its total assets in municipal bonds ("Municipal Bonds") rated, at the time of
purchase, at least "Ba" by Moody's Investor Services, Inc. ("Moody's");  or "BB"
by Standard  and Poor's  Ratings  Group  ("S&P") and Fitch  Investment  Services
("Fitch"),  or, if unrated,  that are of comparable quality as determined by the
Adviser.  Municipal  Bonds  rated  lower  than "Ba" or "BB" may be bought by the
Fund.  However,  the Fund will limit its  investments in such  securities to not
more than 5% of its total assets at the time of purchase. The Fund may invest in
Municipal Bonds with ratings as low as "CC" by S&P or "Ca" by Moody's,  but will
invest in securities  rated lower than ""Ba" or "BB" only where,  in the opinion
of the Adviser,  the rating does not accurately  reflect the true quality of the
credit of the issuer and the quality of such securities is comparable to that of
securities rated at least "Ba" or "BB." The rating limitations applicable to the
Fund's  investments  apply  at  the  time  of  acquisition  of a  security;  any
subsequent  change in the rating or quality of a security  will not  require the
Fund to sell the security.  A general  description  of Moody's,  S&P's and Fitch
ratings is set forth in Appendix B.

Tax Exempt Bonds.  "Tax-exempt securities" are debt obligations generally issued
by or on behalf of states, territories and possessions of the United States, the
District   of   Columbia   and  their   political   subdivisions,   agencies  or
instrumentalities  the  interest on which,  in the opinion of the bond  issuer's
counsel  (not the Fund's  counsel),  is excluded  from gross  income for federal
income tax purposes.  These  securities  consist of Municipal  Bonds,  municipal
notes and  municipal  commercial  paper as well as  variable  or  floating  rate
obligations and participation interests.
    

                                       2
<PAGE>

In  addition to the  hedging  strategies  employed by the Fund in pursuit of its
secondary  objective of  preservation  of capital,  the Fund can purchase  bonds
rated "BBB" and "BB" or "Baa" and "Ba,"  where  based upon price,  yield and the
Adviser's  assessment  of quality,  investment in such bonds is determined to be
consistent with the Fund's  secondary  objective of preserving  capital.  To the
extent  that the Fund  purchases,  retains  or  disposes  of such bonds for this
purpose,  the Fund may not earn as high a yield as might otherwise be obtainable
from lower quality securities.

While the Fund  normally  will  invest  primarily  in medium  and lower  quality
Municipal Bonds as indicated  above, it may invest in higher quality  tax-exempt
securities,   particularly   when  the  difference  in  returns  between  rating
classifications is very narrow.

The same credit quality  standards  would apply to municipal  commercial  paper,
notes and variable rate demand obligations as apply to the Fund's investments in
municipal  bonds.  For example,  these  securities  could be unrated  securities
comparable in quality to  securities  rated BB or Ba or could be rated as low as
CC or Ca by S&P or Moody's.

At the end of any  quarter  of its  taxable  year,  tax-exempt  securities  must
comprise at least 50% of the Fund's total assets.  For liquidity and flexibility
the Fund may place up to 20% of total assets in taxable and tax-free  short-term
securities.  For  defensive  purposes,  it  may  invest  more  assets  in  these
securities.

   
Municipal Obligations. The Fund may invest in a variety of municipal obligations
which consist of municipal bonds, municipal notes and municipal commercial
paper.

Municipal  Bonds.  Municipal bonds are issued to obtain funds for various public
purposes including the construction of a wide range of public facilities such as
airports,  highways, bridges, schools, hospitals,  housing, mass transportation,
streets and water and sewer  works.  Other public  purposes for which  municipal
bonds may be issued include refunding outstanding  obligations,  obtaining funds
for general  operating  expenses  and  obtaining  funds to lend to other  public
institutions   and  facilities.   In  addition,   certain  types  of  industrial
development  bonds (often referred to as "private activity bonds") are issued by
or on behalf  of public  authorities  to obtain  funds for many  types of local,
privately operated facilities. The payment of the principal and interest on such
bonds is generally  dependent  solely on the ability of the  facility's  user to
meet its  financial  obligations  and the pledge,  if any, of real and  personal
property so financed as security for such  payment.  Such debt  instruments  are
considered  municipal  obligations  if the interest  paid on them is exempt from
federal income tax.

The  payment of  principal  and  interest  by  issuers  of  certain  obligations
purchased by the Fund may be guaranteed by a letter of credit,  note  repurchase
agreement,  insurance or other credit  facility  agreement  offered by a bank or
other  financial  institution.  Such  guarantees  and  the  creditworthiness  of
guarantors will be considered by the Adviser in determining  whether a municipal
obligation  meets the Fund's credit  quality  requirements.  No assurance can be
given that a  municipality  or guarantor  will be able to satisfy the payment of
principal or interest on a municipal obligation.

Municipal Notes.  Municipal notes are short-term  obligations of municipalities,
generally with a maturity  ranging from six months to three years. The principal
types of such notes include tax, bond and revenue anticipation notes and project
notes.

Municipal   Commercial  Paper.   Municipal  commercial  paper  is  a  short-term
obligation of a municipality,  generally issued at a discount with a maturity of
less than one year.  Such paper is likely to be issued to meet seasonal  working
capital needs of a municipality  or interim  construction  financing.  Municipal
commercial  paper  is  backed  in many  cases  by  letters  of  credit,  lending
agreements,  note  repurchase  agreements  or other credit  facility  agreements
offered by banks and other institutions.

                                       3
<PAGE>

Federal tax legislation enacted in the 1980s placed substantial new restrictions
on the issuance of the bonds  described  above and in some cases  eliminated the
ability of state or local governments to issue municipal obligations for some of
the above  purposes.  Such  restrictions  do not affect the  Federal  income tax
treatment  of  municipal  obligations  in which the Fund may  invest  which were
issued  prior  to  the  effective   dates  of  the   provisions   imposing  such
restrictions.  The effect of these  restrictions  may be to reduce the volume of
newly issued municipal obligations.

Issuers of municipal  obligations  are subject to the  provisions of bankruptcy,
insolvency and other laws  affecting the rights and remedies of creditors,  such
as the  Federal  Bankruptcy  Act,  and laws,  if any,  which may be  enacted  by
Congress or state  legislatures  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
the principal of and interest on their municipal obligations may be affected.

Commercial  Paper.  The Fund may invest in commercial  paper.  Commercial  paper
represents  short-term unsecured promissory notes issued in bearer form by banks
or bank holding companies,  corporations and finance  companies.  The commercial
paper  purchased  by  the  Fund  consists  of  direct  U.S.  dollar  denominated
obligations of domestic or foreign  issuers.  Bank obligations in which the Fund
may invest include certificates of deposit,  bankers' acceptances and fixed time
deposits.  Certificates  of deposit are negotiable  certificates  issued against
funds deposited in a commercial bank for a definite period of time and earning a
specified return.

Bankers' acceptances are negotiable drafts or bills of exchange,  normally drawn
by an importer or exporter to pay for specific merchandise, which are "accepted"
by a bank, meaning, in effect, that the bank  unconditionally  agrees to pay the
face  value  of the  instrument  on  maturity.  Fixed  time  deposits  are  bank
obligations  payable at a stated  maturity date and bearing  interest at a fixed
rate. Fixed time deposits may be withdrawn on demand by the investor, but may be
subject  to  early  withdrawal   penalties  which  vary  depending  upon  market
conditions  and  the  remaining  maturity  of  the  obligation.   There  are  no
contractual  restrictions  on the right to transfer a  beneficial  interest in a
fixed  time  deposit  to a third  party,  although  there is no market  for such
deposits.  Bank notes and bankers'  acceptances  rank junior to domestic deposit
liabilities of the bank and pari passu with other senior,  unsecured obligations
of the bank.  Bank  notes  are not  insured  by the  Federal  Deposit  Insurance
Corporation  or any other  insurer.  Deposit  notes are  insured by the  Federal
Deposit  Insurance  Corporation only to the extent of $100,000 per depositor per
bank.

Government Securities. The Fund may invest in U.S. Government securities,  which
are  obligations  issued or guaranteed by the U.S.  Government and its agencies,
authorities or instrumentalities.  Certain U.S. Government securities, including
U.S.  Treasury  bills,  notes  and  bonds,  and  Government   National  Mortgage
Association  certificates  ("Ginnie Maes"),  are supported by the full faith and
credit of the United States. Certain other U.S. Government securities, issued or
guaranteed by Federal  agencies or  government  sponsored  enterprises,  are not
supported  by the  full  faith  and  credit  of the  United  States,  but may be
supported  by the right of the issuer to borrow  from the U.S.  Treasury.  These
securities  include  obligations  of the Federal Home Loan Mortgage  Corporation
("Freddie   Macs"),   and   obligations   supported   by  the   credit   of  the
instrumentality,  such as Federal National  Mortgage  Association Bonds ("Fannie
Maes").  No  assurance  can be  given  that  the U.S.  Government  will  provide
financial support to such Federal agencies,  authorities,  instrumentalities and
government sponsored enterprises in the future.

                                       4
<PAGE>

Custodial  Receipts.  The Fund may acquire custodial receipts in respect of U.S.
Government  securities.  Such custodial  receipts  evidence  ownership of future
interest  payments,  principal payments or both on certain notes or bonds. These
custodial  receipts are known by various  names,  including  Treasury  Receipts,
Treasury  Investors  Growth Receipts  ("TIGRs"),  and Certificates of Accrual on
Treasury  Securities  ("CATS").  For certain securities law purposes,  custodial
receipts are not considered U.S. Government securities.

Callable  Bonds.  The Fund may purchase and hold callable  Municipal Bonds which
contain a provision in the indenture  permitting  the issuer to redeem the bonds
prior to their maturity dates at a specified  price which  typically  reflects a
premium  over the bonds'  original  issue  price.  These  bonds  generally  have
call-protection  (a period of time  during  which the bonds may not be  called),
which usually lasts for 7 to 10 years, after which time such bonds may be called
away.  An issuer may  generally  be expected to call its bonds,  or a portion of
them during periods of relatively  declining interest rates, when borrowings may
be replaced at lower rates than those  obtained in prior years.  If the proceeds
of a bond called under such  circumstances  are reinvested,  the result may be a
lower overall yield due to lower current  interest  rates. If the purchase price
of such bonds included a premium related to the appreciated  value of the bonds,
some or all of that  premium may not be recovered  by  bondholders,  such as the
Fund, depending on the price at which such bonds were redeemed.

Ratings as Investment Criteria.
    

Lower Rated High Yield Debt Obligations.  As described in "Investment  Objective
and  Policies,"  the Fund may invest in high yielding debt  securities  that are
rated  below  investment  grade  (i.e.,  rated Baa or lower by Moody's or BBB or
lower by S&P and Fitch).  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. The Fund
may invest in comparable quality unrated securities which, in the opinion of the
Adviser, offer comparable yields and risks to those securities which are rated.

Debt  securities  rated  lower  than  Baa  or  BBB by  Moody's,  S&P  or  Fitch,
respectively and unrated securities of comparable quality (commonly called "junk
bonds") generally have larger price  fluctuations and involve increased risks to
the  principal  and  interest  than do higher  rated  securities.  Many of these
securities are considered to be speculative investments. In general, these risks
include: (1) substantial market price volatility;  (2) changes in credit status,
including weaker overall credit  condition of issuers and risks of default;  and
(3)  industry,  market and  economic  risks,  including  limited  liquidity  and
secondary market support.

The market price and liquidity of lower rated fixed income securities  generally
respond to short-term corporate and market developments to a greater extent than
the price and liquidity of higher rated securities,  because these  developments
are perceived to have a more direct  relationship to the ability of an issuer of
lower rated securities to meet its ongoing debt obligations.

Reduced  volume and  liquidity  in the high  yield high risk bond  market or the
reduced  availability of market quotations may make it more difficult to dispose
of the bonds and to value accurately the Fund's assets. The reduced availability
of reliable,  objective  data may increase the Fund's  reliance on  management's
judgment  in  valuing  high  yield  high risk  bonds.  In  addition,  the Fund's
investments  in high yield high risk  securities  may be  susceptible to adverse
publicity  and investor  perceptions,  whether or not  justified by  fundamental
factors.

The yields of municipal  bonds depend upon,  among other  things,  general money
market conditions,  general  conditions of the municipal bond market,  size of a
particular offering, the maturity of the obligation and rating of the issue. The
ratings of S&P,  Moody's and Fitch  represent their  respective  opinions on the
quality of the municipal  bonds they undertake to rate. It should be emphasized,
however,  that  ratings  are  general  and not  absolute  standards  of quality.
Consequently, municipal bonds with the same maturity, coupon and rating may have
different  yields and  municipal  bonds of the same  maturity  and  coupon  with
different ratings may have the same yield. See the Appendix for a description of
ratings.  Many issuers of securities choose not to have their obligations rated.
Although unrated securities eligible for purchase by the Fund must be determined
to be comparable in quality to securities having certain specified ratings,  the
market for unrated  securities may not be as broad as for rated securities since
many investors rely on rating organizations for credit appraisal.

Credit and Interest  Rate Risks.  Investors  should note that while ratings by a
rating  institution  provide a generally  useful guide to credit risks,  they do
not, nor do they purport to, offer any  criteria for  evaluating  interest  rate
risk.  Changes in the general level of interest rates cause  fluctuations in the
prices of fixed-income  securities already outstanding and will therefore result
in  fluctuation  in net asset value of the shares of the Fund. The extent of the
fluctuation is determined by a complex  interaction of a number of factors.  The
Adviser  will  evaluate  those  factors  it  considers  relevant  and will  make
portfolio  changes when it deems it appropriate in seeking to reduce the risk of
depreciation  in the value of the  Fund's  portfolio.  However,  in  seeking  to
achieve  the  Fund's  primary  objective,  there  will be times,  such as during
periods  of  rising  interest  rates,   when  depreciation  and  realization  of
comparable losses on securities in the portfolio will be unavoidable.  Moreover,
medium and lower-rated  securities and unrated  securities of comparable quality
tend to be subject to wider  fluctuations in yield and market values than higher
rated securities.  Such fluctuations  after a security is acquired do not affect
the cash income  received  from that security but are reflected in the net asset
value of the Fund's portfolio. Other risks of lower quality securities include:

         (i)      subordination to the prior claims of banks and other senior
                  lenders and

         (ii)     the  operation  of mandatory  sinking fund or  call/redemption
                  provisions during periods of declining  interest rates whereby
                  the Fund may reinvest premature  redemption  proceeds in lower
                  yielding portfolio securities.

In determining  which securities to purchase or hold in the Fund's portfolio and
in seeking to reduce  credit and interest rate risk  consistent  with the Fund's
investment  objective and policies,  the Adviser will rely on  information  from
various sources,  including: the rating of the security;  research, analysis and
appraisals of brokers and dealers;  the views of the Trust's Trustees and others
regarding economic  developments and interest rate trends; and the Adviser's own
analysis of factors it deems  relevant as it  pertains to  achieving  the Fund's
investment objectives.

   
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 10% of its net
assets  in  illiquid  investments.  If the  Trustees  determines,  based  upon a
continuing  review of the trading markets for specific Section 4(2) or Rule 144A
securities,  that they are liquid,  they will not be subject to the 10% limit on
illiquid  investments.  The  Trustees may adopt  guidelines  and delegate 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.
    

                                       6
<PAGE>

Participation Interests The Fund may purchase participation interests which give
the Fund an undivided  pro rata interest in a tax-exempt  security.  For certain
participation  interests,  the Fund will have the right to demand payment,  on a
specified number of days' notice for all or any part of the Fund's participation
interest  in  the  tax-exempt  security  plus  accrued  interest.  Participation
interests  which are determined to be not readily  marketable will be considered
illiquid for purposes of the Fund's 10%  restriction  on  investment in illiquid
securities.

The Fund may also  invest  in  certificates  of  participation  ("COPs"),  which
provide  participation  interests  in  lease  revenues.  Each COP  represents  a
proportionate  interest  in or right to the  lease-purchase  payment  made under
municipal  lease  obligations or installment  sales  contracts.  Municipal lease
obligations  are issued by a state or municipal  financing  authority to provide
funds for the construction of facilities  (e.g.,  schools,  dormitories,  office
buildings or prisons) or the acquisition of equipment.  Certain  municipal lease
obligations may trade infrequently. Accordingly, COPs will be monitored pursuant
to analysis by the Adviser and reviewed  according to procedures  adopted by the
Board of Trustees,  which  considers  various  factors in determining  liquidity
risk.  COPs will not be  considered  illiquid  for  purposes  of the  Fund's 10%
limitation on illiquid securities, provided the Adviser determines that there is
a readily available market for such securities. An investment in COPs is subject
to the risk that a municipality  may not  appropriate  sufficient  funds to meet
payments on the underlying lease obligation.

   
Repurchase  Agreements.  The Fund may enter into  repurchase  agreements for the
purpose of realizing additional (taxable) income. In a repurchase agreement Fund
buys a security for a relatively  short period  (generally 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 which the Fund seeks to
enforce its rights thereto, possible subnormal levels of income decline in value
of the  underlying  securities  or lack of access to income during this, as well
as, 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 or securities  firm 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.


                                       7
<PAGE>

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 exceed 5%
of the value of its total assets. 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 debt  securities in which it may invest or on any
securities index based on debt securities in which it may invest.  These options
may be listed on national domestic  securities  exchanges or foreign  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 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.

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  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.

                                       8
<PAGE>

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.  The Fund would
ordinarily  realize  a gain if,  during  the  option  period,  the  value of the
underlying   securities  or  currency   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  purchase  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),  in which  event the  secondary
market on that  exchange (or in that class or series of options)  would cease to
exist although  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.


                                       9
<PAGE>

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 hedge against changes in
interest rates or securities process or for other non-speculative  purposes, the
Fund may  purchase  and  sell  futures  contracts  on debt  securities  and debt
securities indices, 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.  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 interest  rates are rising or  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 interest rates
are falling or 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 rise in
interest  rates or a 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 debt  securities  or  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.

                                       10

<PAGE>

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.

Other  Considerations.  The Fund will  engage in  futures  and  related  options
transactions  solely 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.

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.

                                       11

<PAGE>

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.

Variable  and  Floating  Rate  Obligations.  The Fund may invest in variable and
floating rate obligations, including inverse floating rate obligations, on which
the interest rate is adjusted at predesignated  periodic intervals or when there
is a change in the market rate of interest on which the interest rate payable on
the obligation is based.  Variable and floating rate  obligations  may include a
demand  feature  which  entitles  the  purchaser  to  demand  prepayment  of the
principal  amount  prior  to  stated  maturity.  Also,  the  issuer  may  have a
corresponding  right to prepay the principal  amount prior to maturity.  As with
any other type of debt security,  the marketability of variable or floating rate
instruments  may vary  depending on a number of factors,  including  the type of
issuer and the terms of the  instrument.  The Fund may  invest in more  recently
developed  floating rate  instruments  which are created by dividing a municipal
security's interest rate into two or more different components.  Typically,  one
component  ("floating  rate  component"  or "FRC") pays an interest rate that is
reset  periodically  through an auction  process or by  reference to an interest
rate index.

                                       12
<PAGE>

A second component ("inverse floating rate component" or "IFRC") pays an
interest rate that varies inversely with changes to market rates of interest,
because the interest paid to the IFRC holders is generally determined by
subtracting a variable or floating rate from a predetermined amount (i.e., the
difference between the total interest paid by the municipal security and that
paid by the FRC). The extent of increases and decreases in the value of an IFRC
generally will be greater than comparable changes in the value of an equal
principal amount of a fixed-rate municipal security having similar credit
quality, redemption provisions and maturity. To the extent that such instruments
are not readily marketable, as determined by the Adviser pursuant to guidelines
adopted by the Board of Trustees, they will be considered illiquid for purposes
of the Fund's 10% investment restriction on investment in illiquid securities.

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.

These  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.

                                       13

<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.  If a swap  agreement  provides for payment in different  currencies,  the
parties might agree to exchange the notional principal amount as well. 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 a 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.  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. Short-term trading means the purchase
and subsequent sale of a security after it has been held for a relatively  brief
period of time. The Fund may engage in short-term trading in response to changes
in  interest  rates  or  other  economic  trends  and  developments,  or to take
advantage of yield disparities  between various fixed income securities in order
to realize  capital  gains or improve  income.  Short term  trading may have the
effect of increasing  portfolio turnover rate. A high rate of portfolio turnover
(100% or greater)  involves  correspondingly  greater  brokerage  expenses.  The
Fund's  portfolio  turnover  rate is set  forth in the table  under the  caption
"Financial Highlights" in the Prospectus.

INVESTMENT RESTRICTIONS

Fundamental Investment Restrictions.  The following investment restrictions will
not be changed without approval of a majority of the Fund's  outstanding  voting
securities  which,  as used in the  Prospectus  and this Statement of Additional
Information,  means  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)      Borrow money except from banks for temporary or emergency (not
                  leveraging)  purposes,  including  the  meeting of  redemption
                  requests that might otherwise require the untimely disposition
                  of  securities,  in an  amount  up to 15% of the  value of the
                  Fund's total assets  (including the amount borrowed) valued at
                  market less liabilities (not including the amount borrowed) at
                  the time the borrowing was made. While borrowings exceed 5% of
                  the  value of the  Fund's  total  assets,  the  Fund  will not
                  purchase  any   additional   securities.   Interest   paid  on
                  borrowings will reduce the Fund's net investment  income.  The
                  borrowing  restriction  set forth above does not  prohibit the
                  use of reverse repurchase agreements,  in an amount (including
                  any borrowings) not to exceed 33-1/3% of net assets.

         (2)      Pledge,  hypothecate,   mortgage  or  otherwise  encumber  its
                  assets,  except  in an  amount  up to 10% of the  value of its
                  total assets but only to secure  borrowings  for  temporary or
                  emergency  purposes as may be  necessary  in  connection  with
                  maintaining  collateral in connection with writing put or call
                  options or making initial margin  deposits in connection  with
                  the  purchase or sale of  financial  futures or index  futures
                  contracts and related options.

         (3)      Purchase  securities (except  obligations issued or guaranteed
                  by the U.S. Government,  its agencies or instrumentalities) if
                  the  purchase  would  cause  the Fund at the time to have more
                  than 5% of the  value  of its  total  assets  invested  in the
                  securities  of any one  issuer  or to own more than 10% of the
                  outstanding  debt  securities  of any  one  issuer;  provided,
                  however,  that up to 25% of the value of the Fund's  asset may
                  be invested without regard to these restrictions.

         (4)      Purchase or retain the  securities  of any  issuer,  if to the
                  knowledge of the Fund,  any officer or director of the Fund or
                  its  Adviser  owns  more  than  1/2 of 1% of  the  outstanding
                  securities of such issuer, and all such officers and directors
                  own  in  the  aggregate  more  than  5%  of  the   outstanding
                  securities of such issuer.

         (5)      Write,  purchase or sell puts, calls or combinations  thereof,
                  except  put  and  call  options  on debt  securities,  futures
                  contracts based on debt securities, indices of debt securities
                  and  futures  contracts  based on indices of debt  securities,
                  sell securities on margin or make short sales of securities or
                  maintain  a short  position,  unless at all times when a short
                  position is open it owns an equal amount of such securities or
                  securities  convertible into or exchangeable,  without payment
                  of any further consideration, for securities of the same issue
                  as, and equal in amount to, the  securities  sold  short,  and
                  unless not more than 10% of the  Fund's  net assets  (taken at
                  current value) is held as collateral for such sales at any one
                  time.


                                       15

         (6)      Underwrite the securities of other issuers,  except insofar as
                  the Fund may be deemed an underwriter under the Securities Act
                  of 1933 in disposing of a portfolio security.

         (7)      Purchase the securities of any issuer if as a result more than
                  10% of the value of the Fund's  total assets would be invested
                  in  securities  that  are  subject  to  legal  or  contractual
                  restrictions  on  resale  ("restricted   securities")  and  in
                  securities  for which  there are no readily  available  market
                  quotations;  or enter into a repurchase  agreement maturing in
                  more than seven days, if as a result such repurchase agreement
                  together with  restricted  securities and securities for which
                  there  are  no  readily   available  market  quotations  would
                  constitute more than 10% of the Fund's total assets.

         (8)      Purchase or sell real  estate,  real estate  investment  trust
                  securities,   commodities  or  commodity   contracts,   except
                  commodities and  commodities  contracts which are necessary to
                  enable the Fund to engage in  permitted  futures  and  options
                  transactions necessary to implement hedging strategies, or oil
                  and gas  interests,  but this shall not  prevent the Fund from
                  investing in municipal  obligations  secured by real estate or
                  interests in real estate.

         (9)      Make loans to others,  except insofar as the Fund may enter in
                  repurchase  agreements as set forth in the  Prospectus or this
                  SAI. The purchase of an issue of publicly distributed bonds or
                  other  securities,  whether or not the  purchase was made upon
                  the original  issuance of securities,  is not to be considered
                  the making of a loan.

         (10)     Invest  more than 25% of its assets in the  securities  of the
                  "issuers" in any single industry; provided that there shall be
                  no  limitation  on the purchase of municipal  obligations  and
                  obligations   issued  or   guaranteed  by  the  United  States
                  Government, its agencies or instrumentalities. For purposes of
                  this  limitation and that set forth in investment  restriction
                  (3)  above,  when  the  assets  and  revenues  of  an  agency,
                  authority,  instrumentality or other political subdivision are
                  separate  from those of the  government  creating  the issuing
                  entity  and a  security  is  backed  only  by the  assets  and
                  revenues of the entity,  the entity  would be deemed to be the
                  sole  issuer  of the  security.  Similarly,  in the case of an
                  industrial development or pollution control bond, if that bond
                  is  backed   only  by  the   assets   and   revenues   of  the
                  nongovernmental  user, then such nongovernmental user would be
                  deemed to be the sole issuer. If, however, in either case, the
                  creating   government  or  some  other  entity   guarantees  a
                  security,  such a  guarantee  would be  considered  a separate
                  security  and would be treated as an issue of such  government
                  or other entity.

         (11)     Invest  more than 5% of the  value of its total  assets in the
                  securities of issuers having a record, including predecessors,
                  of fewer  than three  years of  continuous  operation,  except
                  obligations   issued  or   guaranteed  by  the  United  States
                  Government,  its  agencies  or  instrumentalities,  unless the
                  securities  are  rated  by  a  nationally   recognized  rating
                  service.

         (12)  Invest for the purpose of  exercising  control or  management  of
               another company.

         (13)     Issue any senior security (as that term is defined in the 1940
                  Act) if such issuance is  specifically  prohibited by the 1940
                  Act or the rules and regulations promulgated  thereunder.  For
                  the purpose of this restriction,  collateral arrangements with
                  respect to options,  futures  contracts and options on futures
                  contracts and collateral  arrangements with respect to initial
                  and  variation  margins are not deemed to be the issuance of a
                  senior security.

Other Operating Policies

As a matter of operating policy,  the Fund will not 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,  purchase
securities of other investment companies within the John Hancock Group of Funds

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
Trustees of the Trust are also  officers or directors of the Adviser or officers
or directors 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 total  assets  under
management  in its  capacity  as  investment  adviser  to the Fund and the other
mutual funds and publicly traded investment  companies in the John Hancock group
of funds having a combined total of over 1,400,000 shareholders.  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 high ratings from Standard & 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
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 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 of the daily
net assets of the Fund as follows:

               Net Asset Value                            Annual Rate
               ---------------                            -----------
                                    
               The first $75 million                      0.625%
               The next $75 million                       0.5625%
               Over $150 million                          0.50%
            
The Adviser may temporarily  reduce its advisory fee or make other  arrangements
to reduce the Fund's  expenses to a specified  percentage  of average  daily net
assets.  The Adviser retains the right to re-impose the advisory 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.

                                       26

<PAGE>

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 for the Fund 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 the contract  relates,  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 its 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 as long as the Advisory Agreement or
any extension,  renewal or amendment  thereof  remains in effect.  If the Fund's
investment  management  contract 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, 1996, 1997 and 1998,
the Fund paid the Adviser $21,583,  $31,800 and $ ,  respectively,  for services
under this Agreement.
    

In order to avoid conflicts with portfolio  trades for the Fund, the Adviser and
the Fund have adopted extensive  restrictions on personal  securities trading by
personnel of the Adviser and its  affiliates.  Some of these  restrictions  are:
pre-clearance  for all  personal  trades  and a ban on the  purchase  of initial
public offerings,  as well as contributions to specified charities of profits on
securities held for less than 91 days. These  restrictions are a continuation of
the basic  principle  that the interests of the Fund and its  shareholders  come
first.

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 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.  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 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 for the period from  November 1, 1995 to August 31, 1996 and
for the years ended  August 31, 1997 and 1998 were  $161,223,  $215,849  and $ ,
respectively. Of such amounts $17,877, $26,764 and $ , respectively, retained by
John Hancock Funds in 1996,  1997 and 1998.  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 0.25% for Class A shares  and 1.00% for Class B
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 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
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 Plan
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 Plan as a liability of the Fund because the Trustees may terminate Class
B Plan at any time. For the fiscal year ended August 31, 1998, an aggregate of $
of distribution expenses or % of the average net assets of the Class B shares of
the Fund,  was not  reimbursed  or recovered by John Hancock  Funds  through the
receipt of deferred sales charges or Rule 12b-1 fees in prior periods.
    

The Plans were approved by a majority of the voting  securities of the Fund. 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.

                                       28

<PAGE>

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, in any event, be effective unless it is
approved by a vote of a majority of the Trustees and the Independent Trustees of
the Fund. The holders of Class A and Class B 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 each Fund in
proportion to the relative net asset value of the participating Funds.

   
During the fiscal year ended August 31, 1998,  the Fund paid John Hancock  Funds
the following amounts of expenses in connection with their services.

SALES COMPENSATION

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

Compensation  payments  originate from two sources:  from sales charges and from
12b-1 fees that are paid out of the funds'  assets.  The sales charges and 12b-1
fees paid by investors 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 either a reallowance from the initial sales charge or a commission,  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 net
assets. This fee is paid quarterly in arrears.

                                       29

<PAGE>

Financial  services firms selling large amounts of fund shares may receive extra
compensation.  This  compensation,  which John Hancock Funds pays out of its own
resources,  may  include  asset  retention  fees as well  as  reimbursement  for
marketing expenses.

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.

                                       30

<PAGE>

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's net assets by the number of its shares outstanding.

INITIAL SALES CHARGE ON CLASS A 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 shares of the Fund are
described in the Prospectus. Methods of obtaining 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.

   
Without Sales Charge.  Class A shares may be offered  without a front-end  sales
charge or contingent  deferred sales charge ("CDSC") to various  individuals and
institutions as follows:

         *        A Trustee or officer  of the Trust;  a Director  or officer of
                  the Adviser and its affiliates or Selling  Brokers;  employees

                  grandchildren, mother, father, sister, brother, mother-in-law,
                  father-in-law,  daughter-in-law,  son-in-law,  niece,  nephew,
                  grandparents  and same  sex  domestic  partner)  of any of the
                  foregoing;  or any  fund,  pension,  profit  sharing  or other
                  benefit plan of the individuals described above.
    

         *        A broker, dealer, financial planner,  consultant or registered
                  investment  advisor that has entered  into a signed  agreement
                  with John Hancock Funds providing  specifically for the use of
                  Fund shares in fee-based  investment products or services made
                  available to their clients.

         *        A former  participant  in an employee  benefit  plan with John
                  Hancock  funds,  when he or she withdraws from his or her plan
                  and  transfers  any or all  of his or her  plan  distributions
                  directly to the Fund.

         *        A member of a class action lawsuit against insurance companies
                  who is investing settlement proceeds.

                                       31

<PAGE>
   
         *        Retirement plans investing through PruArray Program sponsored
                  by Prudential Securities.
    

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

         *        Retirement  plans  participating  in Merrill  Lynch  servicing
                  programs,  if the Plan has more than $3  million  in assets or
                  500 eligible  employees at the date the Plan Sponsor signs the
                  Merrill Lynch Recordkeeping Service Agreement.

         *        Existing  full  service  clients of the Life  Company who were

                  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 A shares  may  also be  purchased  without  an  initial  sales  charge  in
connection with certain liquidation, merger or acquisition transaction 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).
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 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.

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.

                                       32

<PAGE>
   
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.
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  invested  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 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 Fund to sell,  any  additional  Class A shares and may be  terminated at any
time.

DEFERRED SALES CHARGE ON CLASS B SHARES

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

Contingent  Deferred Sales Charge.  Class B shares which are redeemed within six
years 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 shares being redeemed. No CDSC will be
imposed on  increases  in  account  value  above the  initial  purchase  prices,
including  all 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  purchases  of shares,  all  payments
during a month will be aggregated  and deemed to have been made on the first day
of the month.

                                       33

<PAGE>
   
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  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 this  purpose,  the amount of any
increase in a share's value above its initial  purchase price is not regarded as
a share exempt from 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  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 lot 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 shares,  such as the payment of  compensation  to select Selling Brokers
for selling Class B shares. The combination of the CDSC and the distribution and
service  fees  facilitates  the  ability  of the Fund to sell the Class B 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  shares  and of Class A  shares  of each  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.

*        Redemptions  made  under  certain  liquidation,  merger or  acquisition
         transactions  involving other investment  companies or personal holding

         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 that this waiver does not
         apply to periodic  withdrawal  plan  redemptions of Class A shares that
         are subject to a CDSC).

plans,  Rollover IRA, TSA, 457,  403(b),  401(k),  Money Purchase  Pension Plan,

unless otherwise noted.

         under the Internal Revenue Code.

*        Returns of excess contributions made to these plans.

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 security would be valued for the purpose of making such payment
at the same  value as used in  determining  the 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  solely in 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.
    
                                       36

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 Short-Term Strategic Income Fund
and John Hancock Intermediate Maturity 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
(except John Hancock Short-Term Strategic Income Fund) 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 Class A or
Class B shares of the Fund could be disadvantageous to a shareholder  because of
the initial  sales  charge  payable on  purchases of Class A shares and the CDSC
imposed on  redemptions  of Class B shares and because  redemptions  are taxable
events.  Therefore,  a shareholder should not purchase Class A or Class B shares
at the same  time  that 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).  This program is explained more
fully in the  Prospectus.  The program,  as it relates to  automatic  investment
checks, is subject to the following conditions:

                                       37

<PAGE>

The investments 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 check is not honored by your 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 order date of any investment.

Reinstatement or 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 the Fund or 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 any 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 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 the reinvestment privilege at any time.

A  redemption  or  exchange of shares of the Fund 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 share,  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).

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,  without
further action by  shareholders. 

                                       38

<PAGE>

As of the date of this Statement of Additional Information, the Trustees have
authorized shares of the Fund and one other series. Additional series may be
added in the future. The Declaration of Trust also authorizes the Trustees to
classify and reclassify the shares of the Fund, or any new series of the Trust,
into one or more classes. The Trustees have also authorized the issuance of two
classes of shares of the Fund, designated as Class A and Class B.

The shares of each class of the Fund represent an equal  proportionate  interest
in the aggregate net assets  attributable to that class of the Fund.  Holders of
Class A and Class B 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 Class A and Class B shares will be
borne   exclusively  by  that  class,  (ii)  Class  B  shares  will  pay  higher
distribution and service fees than Class A shares, and (iii) each of Class A and
Class B shares will bear any other class  expenses  properly  allocable  to such
class of shares,  subject to the conditions the Internal Revenue Service imposes
with respect to multiple-class  structures.  Similarly,  the net asset value per
share may vary depending on the class of shares  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  entitled 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.
Fund  shareholders  may  remove a Trustee  by the  affirmative  vote of at least
two-thirds of the Trust'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  Trust.
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 Trust'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  Fund  shareholder  held
personally  liable  by  reason  of  being  or  having  been a  shareholder.  The
Declaration  of Trust also  provides that no series of the Trust shall be liable
for the  liability 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. 

                                       39

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 Fund 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

TAX STATUS

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 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.  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.

                                       40

<PAGE>
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 funds 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
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.

                                       41

<PAGE>

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  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
portfolio  securities that will generate  capital gains or to enter into options
or futures transactions. At the time of an investor's purchase of Fund 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
or loss on the  redemption  or exchange of such shares  within  ninety (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  sixty-one  (61) days  beginning  thirty (30) days before and ending
thirty (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 any  exempt-interest  dividends  paid with  respect to such shares
and,  to the  extent in excess of the  disallowed  amount,  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 this excess
and his pro rata share of these taxes.
    
                                       42

<PAGE>

For Federal  income tax  purposes,  the Fund is permitted to carry forward a net
capital loss in any year to offset net capital gains,  if any,  during the eight
years following the year of the loss. To the extent subsequent net 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. As of
August 31, 1997, the Fund had capital loss  carryforwards of $6,907,488 of which
$2,785,979 expires in 2002, $205,838 expires in 2003, $3,207,633 expires in 2004
and $708,038 expires in 2005.

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

The Fund may invest a substantial portion of its assets 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.

The Fund is required to accrue original issued 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 within
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,  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.

A state  income (and  possibly  local income  and/or  intangible  property)  tax
exemption is generally available to the extent (if any) the Fund's distributions
are derived from interest on (or, in the case of intangibles property taxes, the
value of its assets is attributable to) certain U.S.  Government  obligations or
municipal  obligations of issuers in the state in which a shareholder is subject
to tax,  provided in some states that  certain  thresholds  for holdings of such
obligations and/or reporting requirements are satisfied.  The Fund will not seek
to satisfy any threshold or reporting  requirements that may apply in particular
taxing  jurisdictions,  although  the Fund may in its  sole  discretion  provide
relevant information to shareholders.

                                       43

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.

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  gains  (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, some of the Fund's losses on
its transactions  involving  options and futures  contracts and/or offsetting or
successor  portfolio  positions  may be  deferred  rather  than being taken into
account  currently in calculating the Fund's taxable income or gain.  Certain of
such transactions may also cause the Fund to dispose of investments  sooner than
would  otherwise have occurred.  These  transactions  may thereafter  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.
The discussion does not address special tax rules applicable to certain types of
investors,  such as insurance  companies and financial  institutions.  Dividends
(including exempt-interest dividends),  capital gain distributions and ownership
of or gains realized on the redemption  (including an exchange) of shares of the
Fund may also be subject to state and local taxes.  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 Fund
investment is effectively  connected will be subject to U.S.  Federal income tax
treatment that is different from that described  above.  These  investors may be
subject to nonresident 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 or authorized substitute for Form
W-8 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.

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.

CALCULATION OF PERFORMANCE

For the 30-day period ended August 31, 1998,  the  annualized  yields on Class A
and Class B shares of the Fund were % and %  respectively.  The  average  annual
total return of the Class B shares of the Fund for the 1 year and 5 year periods
ended  August 31,  1998 and since  inception  on August 29, 1986 were %, % and %
respectively  and  reflect  payment  of the  applicable  CDSC  at the end of the
period.

The  average  annual  total  return of Class A shares of the Fund for the 1 year
period ended August 31, 1998 and since inception on December 31, 1993 were % and
%, respectively, and reflect payment of the maximum sales charge.

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 = ( [ (a - b) + 1 ]   - 1
                                        -----                 
Where:                                    cd                  
                          
         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).

   
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 maximum federal tax rate for the 30-day period ended
August 31, 1998 were % and %, respectively.

                                       45

Total return is computed by finding the average annual compounded rate of return
over the 1 year,  5 year and life-of  fund periods 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  hypothetical  $1,000
                           investment  made at the  beginning  of the 1 year,  5
                           year and life-of-fund periods.

   
Because each share has its own sales charge and fee structure,  the classes have
different  performance  results.  In the case of Class A or Class B shares, 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 also
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 shares into account. Excluding the Fund's sales charge on
Class A shares and the CDSC on Class B 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 of 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 the Russell and Wilshire Indices.

Performance  rankings and ratings  reported  periodically in national  financial
publications  such as MONEY  Magazine,  FORBES,  BUSINESS  WEEK, THE WALL STREET
JOURNAL,  MORNINGSTAR, and BARRON'S 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.

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 other  policies  that 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,  each 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
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  commitments  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 and practices of
the Adviser 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,  1998 and 1997,  the Fund paid $ and $
47,181, respectively,  in negotiated brokerage commissions. For the period ended
August 31, 1996, the Fund paid $12,578 in negotiated brokerage commissions.

                                       47

<PAGE>

As permitted by Section 28(e) of the  Securities  Exchange Act of 1934, the Fund
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  Directors  that  the  price is
reasonable in light of the services  provided and to policies that the Directors
may adopt from time to time.  During the period  ended  August 31,  1996 and the
fiscal years ended August 31, 1997 and 1998, the Fund did not pay commissions to
compensate 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 John Hancock Distributors,  Inc., a broker dealer ("Distributors"
or "Affiliated Brokers").  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 Affiliated  Brokers.  During the
period  ended  August 31,  1996,  and the fiscal years ended August 31, 1997 and
1998,  the Fund did not  execute  any  portfolio  transactions  with  Affiliated
Brokers.
    

Distributors 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 a 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  Brokers.  Because the Adviser,
which is affiliated with the Affiliated  Brokers,  has, as an investment adviser
to the Fund, 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  Brokers  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 and 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.  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 of the Fund. The Fund pays Signature Services
an annual fee of $20.00 for each Class A shareholder account and $22.50 for each
Class B shareholder account, plus certain out-of-pocket expenses. These expenses
are  aggregated and charged to the Fund and allocated to each class on the basis
of their relative net asset values.

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).

                                      A-1

<PAGE>

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).

     oHedged  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.

     oSpeculative  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.

     oLiquidity  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

CORPORATE AND TAX-EXEMPT BOND RATINGS


Moody's Investors Service, Inc. ("Moody's)

Aaa,  Aa, A and Baa -  Tax-exempt  bonds rated Aaa are judged to be of the "best
quality." The rating of Aa is assigned to bonds that are of "high quality by all
standards," but long-term risks appear somewhat larger than Aaa rated bonds. The
Aaa and Aa rated bonds are generally  known as "high grade bonds." The foregoing
ratings  for  tax-exempt  bonds  are  rated  conditionally.  Bonds for which the
security depends upon the completion of some act or upon the fulfillment of some
condition  are rated  conditionally.  These are bonds secured by (a) earnings of
projects under  construction,  (b) earnings of projects  unseasoned in operation
experience,  (c)  rentals  that  begin when  facilities  are  completed,  or (d)
payments  to which some other  limiting  condition  attaches.  Such  conditional
ratings denote the probable  credit stature upon  completion of  construction or
elimination of the basis of the condition. Bonds rated A are considered as upper
medium grade obligations.  Principal and interest are considered  adequate,  but
elements may be present which suggest a susceptibility to impairment sometime in
the future.  Bonds rated Baa are  considered a 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.

Ba,  B, Caa,  Ca - 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 the  characteristics  of  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.


Standard & Poor's Ratings Group ("S&P")

AAA,  AA, A and BBB - Bonds rated AAA bear the highest  rating  assigned to debt
obligations,  which indicates an extremely  strong capacity to pay principal and
interest.  Bonds rated AA are  considered  "high  grade," are only slightly less
marked  than those of AAA  ratings and have the second  strongest  capacity  for
payment of debt service.  Bonds rated A have a strong  capacity to pay principal
and interest,  although they are somewhat  susceptible to the adverse effects of
changes in  circumstances  and economic  conditions.  The foregoing  ratings are
sometimes  followed  by a "p"  indicating  that the  rating  is  provisional.  A
provisional rating assumes the successful  completion of the project financed by
the bonds being rated and indicates that payment of debt service requirements is
largely or entirely  dependent upon the successful and timely  completion of the
project.

                                      B-1

<PAGE>

Although a provisional rating addresses credit quality subsequent to completion
of the project, it makes no comment on the likelihood of, or the risk of default
upon failure of, such completion. Bonds rated BBB are regarded as having an
adequate capacity to repay principal and pay interest. Whereas they normally
exhibit protection parameters, adverse economic conditions or changing
circumstances are more likely to lead to a weakened capacity to repay principal
and pay interest for bonds in this category than for bonds in the A category.

BB, B, CCC,  CC - Debt  rated BB, B, CCC and CC is  regarded,  on  balanced,  as
predominantly  speculative  with  respect to capacity to pay  interest and repay
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
are  outweighed  by large  uncertainties  or major  risk  exposures  to  adverse
conditions.

Fitch Investors Service ("Fitch")

AAA, AA, A, BBB - Bonds rated AAA are  considered to be investment  grade and of
the highest quality.  The obligor has an  extraordinary  ability to pay interest
and repay principal,  which is unlikely to be affected by reasonably foreseeable
events.  Bonds  rated  AA are  considered  to be  investment  grade  and of high
quality.  The obligor's ability to pay interest and repay principal,  while very
strong,  is  somewhat  less than for AAA rated  securities  or more  subject  to
possible  change over the term of the issue.  Bonds rated A are considered to be
investment grade and of good 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.  Bonds  rated  BBB  are  considered  to  be  investment  grade  and  of
satisfactory  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 weaken this ability than bonds with
higher ratings.

BB, B, CCC,  CC - Debt  rated BB, B, CCC and CC is  regarded,  on  balanced,  as
predominantly  speculative  with  respect to capacity to pay  interest and repay
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
are  outweighed  by large  uncertainties  or major  risk  exposures  to  adverse
conditions.


TAX-EXEMPT NOTE RATINGS

Moody's - MIG-1  and  MIG-2.  Notes  rated  MIG-1  are  judged to be of the best
quality,  enjoying  strong  protection from  established  cash flow or funds for
their  services or from  established  and  broad-based  access to the market for
refinancing  or both.  Notes rated MIG-2 are judged to be of high  quality  with
ample margins of protection, though not as large as MIG-1.

S&P - SP-1 and SP-2.  SP-1  denotes a very  strong  or  strong  capacity  to pay
principal  and  interest.  Issues  determined  to  possess  overwhelming  safety
characteristics  are  given a plus  (+)  designation  (SP-1+).  SP-2  denotes  a
satisfactory capacity to pay principal and interest.

Fitch - FIN-1 and  FIN-2.  Notes  assigned  FIN-1  are  regarded  as having  the
strongest  degree of assurance for timely payment.  A plus symbol may be used to
indicate relative  standing.  Notes assigned FIN-2 reflect a degree of assurance
for timely payment only slightly less in degree than the highest category.

                                      B-2

<PAGE>

CORPORATE AND TAX-EXEMPT COMMERCIAL PAPER RATINGS

Moody's -  Commercial  Paper  ratings are  opinions of the ability of issuers to
repay  punctually  promissory  obligations  not having an  original  maturity in
excess of nine months. Prime-1,  indicates highest quality repayment capacity of
rated issue and Prime-2 indicates higher quality.

S&P - Commercial  Paper ratings are a current  assessment  of the  likelihood of
timely  payment of debts  having an original  maturity of no more than 365 days.
Issues  rated  A have  the  greatest  capacity  for a  timely  payment  and  the
designation  1, 2 and 3 indicates  the relative  degree of safety.  Issues rated
"A-1+" are those with an "overwhelming degree of credit protection."

Fitch - Commercial  Paper  ratings  reflect  current  appraisal of the degree of
assurance of timely  payment.  F-1 issues are  regarded as having the  strongest
degree of assurance  for timely  payment.  (+) is used to designate the relative
position  of an issuer  within  the  rating  category.  F-2  issues  reflect  an
assurance of timely  payment  only  slightly  less in degree than the  strongest
issues.  The symbol (LOC) may follow either category and indicates that a letter
of credit issued by a commercial bank is attached to the commercial paper note.

Other  Considerations - The ratings of S&P,  Moody's,  and Fitch represent their
respective opinions of the quality of the municipal securities they undertake to
rate.  It should be  emphasized,  however,  that ratings are general and are not
absolute standards of quality. Consequently,  municipal securities with the same
maturity,  coupon and ratings may have different yields and municipal securities
of the same maturity and coupon with different ratings may have the same yield.

It is  assumed  that an  investor  filing  a  single  return  is not a "head  of
household,"  a "married  individual  filing a separate  return," or a "surviving
spouse." The table does not take into account the effects of  reductions  in the
deductibility of itemized  deductions or the phaseout of personal exemptions for
taxpayers with adjusted gross incomes in excess of specified  amounts.  Further,
the table does not attempt to show any  alternative  minimum  tax  consequences,
which will depend on each  shareholder's  particular  tax situation and may vary
according to what portion,  it any, of the Fund's  exempt-interest  dividends is
attributable  to interest on certain  private  activity bonds for any particular
taxable  year. No assurance can be given that the Fund will achieve any specific
tax-exempt  yield or that all of its income  distributions  will be  tax-exempt.
Distributions  attributable  to any taxable  income or capital gains realized by
the Fund will not be tax-exempt.

The  information  set  forth  above  is as of the  date  of  this  Statement  of
Additional  Information.  Subsequent tax law changes could result in prospective
or retroactive changes in the tax brackets, tax rates, and tax-equivalent yields
set forth above.

This table is for  illustrative  purposes  only and is not  intended to imply or
guarantee  any  particular  yield  from the Fund.  While it is  expected  that a
substantial   portion  of  the  interest   income   distributed  to  the  fund's
shareholders  will  be  exempt  from  federal  income  taxes,  portions  of such
distributions from time to time may be subject to federal income taxes.

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 the approval of John Hancock  Advisers,  Inc. (the  "Adviser"),  as the
Fund's adviser  effective  December 22, 1994, the Fund was known as Transamerica
Tax-Free Income Fund. The Adviser is an indirect wholly owned subsidiary of 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.

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 is fundamental
and may only be changed with  shareholder  approval.  There is no assurance that
the Fund will achieve its investment objective.

The Fund is a "diversified"  management  investment company under the Investment
Company Act of 1940 (the "1940 Act"). This means that with respect to 75% of its
total  assets:  (1) the Fund may not invest more than 5% of its total  assets in
the  securities  of any one issuer  other than U.S.  government  securities  and
securities of other investment  companies and (2) the Fund may not own more than
10% of the outstanding  voting  securities of any one issuer.  In applying these
limitations,  a guarantee of a security will not be considered a security of the
guarantor,  provided  that the value of all  securities  issued or guaranteed by
that  guarantor,  and owned by the Fund,  does not  exceed  10% of Fund's  total
assets.  Since Municipal  Obligations  ordinarily  purchased by the Fund are not
voting securities (notwithstanding the 75% limitation described above), there is
generally no limit on the percentage of a single issuer's  obligations which the
Fund may own so long as it does not invest  more than 5% of its total  assets in
the  securities of that issuer.  Consequently,  the Fund may invest in a greater
percentage  of the  outstanding  securities  of a single  issuer  than  would an
investment company which invests in voting securities. In determining the issuer
of  a  security,  each  state  and  each  political  subdivision,   agency,  and
instrumentality of each state and each multi-state agency of which such state is
a member is a separate  issuer.  Where  securities are backed only by assets and
revenues of a particular instrumentality,  facility or subdivision,  such entity
is considered the issuer.
    

The Fund seeks to achieve its  objective  by  investing  primarily  in municipal
bonds,  notes and commercial paper, the interest on which is exempt from federal
income  taxes  ("Municipal   Obligations"  or  "Municipal   Bonds").   Municipal
Obligations  include  debt  obligations  issued  by  or  on  behalf  of  states,
territories or possessions of the United States;  the District of Columbia,  and
the political subdivisions, agencies or instrumentalities thereof.

Under normal market  conditions  the Fund invests at least 80% of it's assets in
Municipal  Bonds.  The Fund's  Municipal Bonds include  investment  grade bonds,
notes and  commercial  paper.  This  policy is  consistent  with the SEC staff's
current position about using the word bond in the Fund's name.

For liquidity and  flexibility,  the Fund may place up to 20% of total assets in
taxable investment grade short-term  securities.  For defensive purposes, it may
invest more assets in these securities.

   
Municipal Obligations.  In seeking to achieve its investment objective, the Fund
invests in a variety of Municipal  Obligations which consist of Municipal Bonds,
Municipal  Notes and Municipal  Commercial  Paper,  the interest on which in the
opinion of the bond  issuer's  counsel  (not the Fund's  counsel) is exempt from
federal income tax.
    

                                       2

<PAGE>

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.

Municipal bonds are issued to obtain funds for various public purposes including
the  construction  of a wide  range  of  public  facilities  such  as  airports,
highways, bridges, schools, hospitals, housing, mass transportation, streets and
water and sewer works.  Other public  purposes for which  Municipal Bonds may be
issued include refunding  outstanding  obligations,  obtaining funds for general
operating expenses and obtaining funds to lend to other public  institutions and
facilities.  In addition,  certain  types of  industrial  development  bonds are
issued by or on behalf of public  authorities  to obtain funds for many types of
local,  privately  operated  facilities.  Such debt  instruments  are considered
municipal obligations if the interest paid on them is exempt from federal income
tax.  The payment of principal  and  interest by issuers of certain  obligations
purchased by the Fund may be guaranteed by a letter of credit,  note  repurchase
agreement,  insurance or other credit  facility  agreement  offered by a bank or
other  financial  institution.  Such  guarantees  and  the  creditworthiness  of
guarantors will be considered by the Adviser in determining  whether a Municipal
Obligation meets the Fund's investment quality requirements. No assurance can be
given that a  municipality  or guarantor  will be able to satisfy the payment of
principal or interest on a municipal obligation.

Municipal Notes.  Municipal Notes are short-term  obligations of municipalities,
generally with a maturity  ranging from six months to three years. The principal
types of such Notes include tax, bond and revenue anticipation notes and project
notes.

Municipal   Commercial  Paper.   Municipal  Commercial  Paper  is  a  short-term
obligation of a municipality,  generally issued at a discount with a maturity of
less than one year.  Such paper is likely to be issued to meet seasonal  working
capital needs of a municipality  or interim  construction  financing.  Municipal
Commercial  Paper  is  backed  in many  cases  by  letters  of  credit,  lending
agreements,  note  repurchase  agreements  or other credit  facility  agreements
offered by banks and other institutions.

Federal  tax   legislation   enacted  in  the  1980's  placed   substantial  new
restrictions  on the  issuance  of the bonds  described  above and in some cases
eliminated  the  ability  of  state  or local  governments  to  issue  Municipal
Obligations for some of the above purposes.  Such restrictions do not affect the
Federal  income tax  treatment  of Municipal  Obligations  in which the Fund may
invest which were issued prior to the effective dates of the provisions imposing
such restrictions.  The effect of these restrictions may be to reduce the volume
of newly issued Municipal Obligations.

Issuers of Municipal  Obligations  are subject to the  provisions of bankruptcy,
insolvency and other laws  affecting the rights and remedies of creditors,  such
as the  Federal  Bankruptcy  Act,  and laws,  if any,  which may be  enacted  by
Congress or state  legislatures  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
the principal of and interest on their Municipal Obligations may be affected.

   
The yields of Municipal  Bonds depend upon,  among other  things,  general money
market conditions,  general  conditions of the Municipal Bond market,  size of a
particular offering, the maturity of the obligation and rating of the issue. The
ratings of Standard and Poor's Rating Group ("S&P"),  Moody's Investor Services,
Inc.  ("Moody's")  and  Fitch  Investment  Services  ("Fitch")  represent  their
respective  opinions of the quality of the  Municipal  Bonds they  undertake  to
rate.  It should be  emphasized,  however,  that  ratings  are  general  and not
absolute  standards  of  quality.  Consequently,  Municipal  Bonds with the same

                                       3

<PAGE>

maturity, coupon and rating may have different yields and Municipal Bonds of the
same  maturity and coupon with  different  ratings may have the same yield.  See
Appendix B for a description of ratings.  Many issuers of securities  choose not
to have their  obligations  rated.  Although  unrated  securities  eligible  for
purchase  by the  Fund  must  be  determined  to be  comparable  in  quality  to
securities having certain specified  ratings,  the market for unrated securities
may not be as broad as for rated  securities since many investors rely on rating
organizations for credit appraisal.
    

Ratings as Investment Criteria.  The Fund may invest less than 35% of its assets
in municipal bonds,  including private activity bonds, and municipal notes rated
at the time of purchase  Ba or B by Moody's,  BB or B by S&P or Fitch or, if not
rated,  determined by the Adviser to be of comparable credit quality.  Municipal
commercial  paper like the Fund's other  municipal  investments  can be of below
investment  grade  quality  and  maybe  rated or  unrated.  The Fund may  retain
Municipal  Obligations  whose ratings are downgraded below  permissible  ratings
until the Adviser  determines that disposing of such  Obligations is in the best
interests of the Fund.

Municipal  bonds  and  notes  rated  BBB or Baa  are  considered  to  have  some
speculative  characteristics and can pose special risks involving the ability of
the issuer to make  payment of principal  and interest to a greater  extent than
higher  rated  securities.  Municipal  bonds and notes  rated BB, B, Ba or B are
considered  speculative  and are  generally  referred  to as junk  bonds.  While
generally   providing   greater  income  than   investments  in  higher  quality
securities, these instruments involve greater risk of principal and income loss,
including the possibility of default.  These  instruments may have greater price
volatility,  especially during periods of economic  uncertainty or change. Bonds
rated B are currently  meeting debt service  requirements  but provide a limited
margin of safety and are vulnerable to default in the event of adverse business,
financial or economic conditions.  In addition, the market for these instruments
may be less liquid than the market for higher rated securities.  Therefore,  the
Adviser's  judgment  at  times  plays  a  greater  role in the  performance  and
valuation of the Fund's  investments  in these  instruments.  See Appendix B for
additional discussion of the ratings assigned to Municipal Obligations.

The Adviser  will  purchase  municipal  bonds rated BBB, BB or B or Baa, Ba or B
where, based upon price, yield and its assessment of quality, investment in such
bonds is determined to be consistent  with the Fund's  objective of preservation
of  capital.   The  Adviser  will  evaluate  and  monitor  the  quality  of  all
investments,  including  bonds  rated  BBB,  BB or B or Baa,  Ba or B,  and will
dispose of such bonds  necessary to assure that the Fund's overall  portfolio is
constituted in manner  consistent with the goal of  preservation of capital.  To
the extent that the Fund's  investments in municipal bonds rated BBB, BB or B or
Baa, Ba or B includes  obligations  believed to be  consistent  with the goal of
preserving capital,  such bonds may not provide yields as high as those of other
obligations  having such  ratings and the  differential  in yields  between such
bonds and  obligations  with higher quality ratings may not be as significant as
might otherwise be generally available.

Because there is no restriction  on the maturities of the Municipal  Obligations
in which the Fund may  invest,  the Fund's  average  portfolio  maturity  is not
subject to any limit. Generally,  the longer the average portfolio maturity, the
greater will be the impact of  fluctuations  in interest  rates on the values of
the Fund's assets and on the net asset value per share.

   
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 10% of its net
assets  in  illiquid  investments.  If the  Trustees  determines,  based  upon a
continuing  review of the trading markets for specific Section 4(2) or Rule 144A
securities,  that they are liquid,  they will not be subject to the 10% limit on

                                       4

<PAGE>

illiquid  investments.  The  Trustees may adopt  guidelines  and delegate 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.  The Fund may purchase from financial institutions tax
exempt  participation  interests  in  tax  exempt  securities.  A  participation
interest gives the Fund an undivided  interest in the tax exempt security in the
proportion that the Fund's  participation  interest bears to the total amount of
the tax exempt security. For certain participation interests, the Fund will have
the right to demand payment,  on a specified number of days' notice,  for all or
any part of the Fund's  participation  interest in the tax exempt  security plus
accrued  interest.  Participation  interests,  which  are  determined  to be not
readily  marketable,  will be  considered as such for purposes of the Fund's 10%
investment   restriction  on  investment  in  non-readily   marketable  illiquid
securities.  The Fund may also invest in Certificates of  Participation  (COP's)
which  provide  participation  interests  in lease  revenues.  Each  Certificate
represents a proportionate  interest in or right to the  lease-purchase  payment
made  under  municipal  lease   obligations  or  installment   sales  contracts.
Typically,  municipal  lease  obligations  are  issued  by a state or  municipal
financing  authority to provide funds for the construction of facilities  (e.g.,
schools,  dormitories,  office  buildings  or  prisons)  or the  acquisition  of
equipment.  The  facilities  are  typically  used by the  state or  municipality
pursuant  to a  lease  with  a  financing  authority.  Certain  municipal  lease
obligations may trade infrequently.  Participation  interests in municipal lease
obligations  will not be  considered  illiquid  for  purposes  of the Fund's 10%
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.

The Fund  may  engage  in  short-term  trading  consistent  with its  investment
objective. Securities may be sold in anticipation of a market decline (a rise in
interest  rates) or  purchased  in  anticipation  of a market rise (a decline in
interest  rates).  In addition,  a security may be sold and another  security of
comparable quality purchased at approximately the same time to take advantage of
what the  Adviser  believes  to be a  temporary  disparity  in the normal  yield
relationship  between the two securities.  These yield disparities may occur for
reasons not directly related to the investment  quality of particular  issues or
the general  movement of interest  rates,  such as changes in the overall demand
for, or supply of, various types of tax- exempt securities.

In general, purchases and sales may also be made to restructure the portfolio in
terms of average maturity,  quality, coupon yield or diversification for any one
or more of the  following  purposes:  (a) to  increase  income,  (b) to  improve
portfolio quality, (c) to minimize capital depreciation, (d) to realize gains or
losses,  or (e) for such other reasons as the Adviser deems relevant in light of
economic or market conditions.
       

                                       5

<PAGE>

Repurchase  Agreements.  The Fund  may  enter  into  repurchase  agreements  for
purposes 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,  decline in
value of the  underlying  securities  or lack of access to  income  during  this
period as well as 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 15% 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  exceed 5% of the value of its total assets.  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 debt  securities in which it may invest or on any
securities index based on debt securities in which it may invest.  These options
may be listed on national domestic  securities  exchanges or foreign  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 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.

                                       6

<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  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.  The Fund would
ordinarily  realize  a gain if,  during  the  option  period,  the  value of the
underlying   securities  or  currency   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  purchase  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.

                                       7

<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),  in which  event the  secondary
market on that  exchange (or in that class or series of options)  would cease to
exist although  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 hedge against changes in
interest  rates or  securities  prices,  the Fund may  purchase and sell futures
contracts on debt securities and debt securities indices, 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.  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 interest  rates are rising or  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 interest rates
are falling or 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.

                                       8

<PAGE>

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 rise in
interest  rates or a 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 debt  securities  or  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.

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.

Other  Considerations.  The Fund will  engage in  futures  and  related  options
transactions  solely 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.

                                       9

<PAGE>

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.

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.

Variable or Floating Rate  Obligations.  Certain of the obligations in which the
Fund may  invest may be  variable  or  floating  rate  obligations  on which the
interest rate is adjusted at predesignated periodic intervals (variable rate) or
when there is a change in the market rate of interest on which the interest rate
payable on the obligation is based  (floating  rate).  Variable or floating rate
obligations  may include a demand feature which entitles the purchaser to demand
prepayment of the principal  amount prior to stated  maturity.  Also, the issuer
may have a corresponding right to prepay the principal amount prior to maturity.
As with any other  type of debt  security,  the  marketability  of  variable  or
floating rate instruments may vary depending upon a number of factors, including
the type of issuer and the terms of the instruments. The Fund may also invest in
more recently  developed floating rate instruments which are created by dividing
a municipal  security's  interest  rate into two or more  different  components.
Typically,  one component  ("floating rate component" or "FRC") pays an interest
rate that is reset periodically through an auction process or by reference to an
interest rate index. A second  component  ("inverse  floating rate component" or
"IFRC") pays an interest rate that varies inversely with changes to market rates
of  interest,  because  the  interest  paid to the  IFRC  holders  is  generally
determined  by  subtracting  a variable  or floating  rate from a  predetermined
amount (i.e.,  the  difference  between the total interest paid by the municipal
security  and  that  paid by the  FRC).  The  Fund may  purchase  FRC's  without
limitation. Up to 10% of the Fund's total assets may be invested in IFRC's in an
attempt to protect  against a reduction in the income earned on the Fund's other
investments  due to a decline in interest  rates.  The extent of  increases  and
decreases  in the value of an IFRC  generally  will be greater  than  comparable
changes  in the value of an equal  principal  amount of a  fixed-rate  municipal
security having similar credit quality,  redemption  provisions and maturity. To
the extent that such  instruments are not readily  marketable,  as determined by
the  Adviser  pursuant  to  guidelines  adopted  by the  Trustees,  they will be
considered  illiquid for purposes of the Fund's 10%  investment  restriction  on
investment in non-readily marketable securities.

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.

These  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  and  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.

                                       11

<PAGE>

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  losing  the
opportunity  to obtain a price  and yield  considered  to be  advantageous.  The
purchase  of  securities  on a when-  issued and 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.  If a swap  agreement  provides for payment in different  currencies,  the
parties might agree to exchange the notional principal amount as well. 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 a 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.  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.
    
                                       12

<PAGE>

Short Term Trading and Portfolio Turnover. Short-term trading means the purchase
and subsequent sale of a security after it has been held for a relatively  brief
period of time. The Fund may engage in short-term trading in response to changes
in  interest  rates  or  other  economic  trends  and  developments,  or to take
advantage of yield disparities  between various fixed income securities in order
to realize  capital  gains or improve  income.  Short term  trading may have the
effect of increasing  portfolio turnover rate. A high rate of portfolio turnover
(100% or greater)  involves  correspondingly  greater  brokerage  expenses.  The
Fund's  portfolio  turnover  rate is set  forth in the table  under the  caption
"Financial Highlights" in the Prospectus.

INVESTMENT RESTRICTIONS

   
Fundamental Investment Restrictions.  The following investment restrictions will
not be changed without approval of a majority of the Fund's  outstanding  voting
securities  which,  as used in the  Prospectus  and this Statement of Additional
Information,  means  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. Borrow money  except from banks for  temporary or emergency
                  (not leveraging) purposes, including the meeting of redemption
                  requests that might otherwise require the untimely disposition
                  of  securities,  in an  amount  up to 15% of the  value of the
                  Fund's total assets  (including the amount borrowed) valued at
                  market less liabilities (not including the amount borrowed) at
                  the time the borrowings was made. While borrowing exceed 5% of
                  the  value of the  Fund's  total  assets,  the  Fund  will not
                  purchase any additional securities. Interest paid on borrowing
                  will reduce the Fund's net investment income.

                  2. Pledge,  hypothecate,  mortgage or  otherwise  encumber its
                  assets,  except  in an  amount  up to 10% of the  value of its
                  total  assets but only to secure  borrowing  for  temporary or
                  emergency  purposes or as may be necessary in connection  with
                  maintaining collateral in connection with writing put and call
                  options or making initial margin  deposits in connection  with
                  the  purchase  or sale of  financial  futures,  index  futures
                  contracts and related options.

                  3.  With  respect  to  75%  of  its  total  assets,   purchase
                  securities (other than obligations issued or guaranteed by the
                  United States  government,  its agencies of  instrumentalities
                  and shares of other investment companies) of any issuer if the
                  purchase would cause  immediately  thereafter  more than 5% of
                  the value of the Fund's  total  assets to be  invested  in the
                  securities  of such issuer or the Fund would own more than 10%
                  of the outstanding voting securities of such issuer.

                  4. Make  loans to  others,  except  through  the  purchase  of
                  obligations  in  which  the  Fund  is  authorized  to  invest,
                  entering  in  repurchase   agreements  and  lending  portfolio
                  securities  in an amount not  exceeding one third of its total
                  assets.

                  5. Purchase illiquid securities,  including securities subject
                  to  restrictions  on  disposition  under the Securities Act of
                  1933,  repurchase agreements maturing in more than seven days,
                  and  securities  which do not have  readily  available  market
                  quotations, if such purchase would cause the Fund to have more
                  than  10%  of  its  net  assets  invested  in  such  types  of
                  securities.

                  6. Purchase or retain the  securities of any issuer,  if those
                  officers  and  Trustees  of the  Fund or the  Adviser  who own
                  beneficially  more  than 1/2 of 1% of the  securities  of such
                  issuer,  together own more than 5% of the  securities  of such
                  issuer.

                  7.  Write,  purchase  or  sell  puts,  calls  or  combinations
                  thereof,  except  put and  call  options  on debt  securities,
                  futures  contracts based on debt  securities,  indices of debt
                  securities  and  futures  contracts  based on  indices of debt
                  securities,  sell  securities on margin or make short sales of
                  securities or maintain a short  position,  unless at all times
                  when a short  position is open it owns an equal amount of such
                  securities or  securities  convertible  into or  exchangeable,
                  without payment of any further  consideration,  for securities
                  of the same issue as,  and equal in amount to, the  securities
                  sold  short,  and  unless  not more than 10% of the Fund's net
                  assets (taken at current value) is held as collateral for such
                  sales at any one time.

                  8. Underwrite the securities of other issuers,  except insofar
                  as the Fund may be deemed an underwriter  under the Securities
                  Act of 1933 in disposing of a portfolio security.

                  9. Purchase or sell real estate,  real estate investment trust
                  securities,   commodities  or  commodity   contracts,   except
                  commodities and  commodities  contracts which are necessary to
                  enable the Fund to engage in  permitted  futures  and  options
                  transactions necessary to implement hedging strategies, or oil
                  and gas interests.  This limitation shall not prevent the Fund
                  from investing in municipal  securities secured by real estate
                  or interests in real estate or holding real estate acquired as
                  a result of owning such municipal securities.

                  10.   Invest  in  common  stock  or  in  securities  of  other
                  investment  companies,  except that  securities  of investment
                  companies  may be acquired as part of a merger,  consolidation
                  or  acquisition  of  assets  and  units  of  registered   unit
                  investment  trusts  whose  assets  consist   substantially  of
                  tax-exempt  securities may be acquired to the extent permitted
                  by Section 12 of the Act or applicable rules.

                  11.  Invest more than 25% of its assets in the  securities  of
                  "issuers" in any single industry; provided that there shall be
                  no  limitation  on  the  purchase  of  obligations  issued  or
                  guaranteed  by the United States  Government,  its agencies or
                  instrumentalities  or by any  state or  political  subdivision
                  thereof.  For purposes of this  limitation when the assets and
                  revenues  of an agency,  authority,  instrumentality  or other
                  political   subdivision   are  separate   from  those  of  the
                  government  creating  the  issuing  entity and a  security  is
                  backed  only by the assets and  revenues  of the  entity,  the
                  entity would be deemed to be the sole issuer of the  security.
                  Similarly,  in  the  case  of  an  industrial  development  or
                  pollution  control  bond,  if that bond is backed  only by the
                  assets and  revenues of the  nongovernmental  user,  then such
                  nongovernmental  user  would be deemed to be the sole  issuer.
                  If, however,  in either case, the creating  government or some
                  other entity guarantees a security,  such a guarantee would be
                  considered  a  separate  security  and would be  treated as an
                  issue of such  government  or other entity unless the value of
                  all securities issued or guaranteed by the government or other
                  entity  owned by the Fund does not  exceed  10% of the  Fund's
                  total assets.

                  12.  Invest more than 5% of its total assets in  securities of
                  any issuers if the party  responsible  for  payment,  together
                  with any  predecessor,  has been in  operation  for less  than
                  three years (except U.S. government and agency obligations and
                  obligations  backed by the faith,  credit and taxing  power of
                  any person authorized to issue tax exempt securities).

                  13. Issue any senior  securities,  except  insofar as the Fund
                  may be deemed to have issued a senior  security  by:  entering
                  into  a  repurchase  agreement;  purchasing  securities  on  a
                  when-issued or delayed  delivery basis;  purchasing or selling
                  any options or financial futures contract;  borrowing money or
                  lending  securities in accordance with  applicable  investment
                  restrictions.

The Trustees  have  approved the  following  non-fundamental  investment  policy
pursuant to an order of the SEC:  Notwithstanding any investment  restriction to
the contrary,  the Fund may, in connection  with the John Hancock Group of Funds
Deferred  Compensation  Plan for Independent  Trustees,  purchase  securities of
other investment companies within the John Hancock Group of Funds provided that,
as a result,  (i) no more than 10% of the Fund's  assets  would be  invested  in
securities  of all other  investment  companies,  (ii) such  purchase  would not
result in more than 3% of the total  outstanding  voting  securities  of any one
such investment  company being held by the Fund and (iii) no more than 5% of the
Fund's assets would be invested in any one such investment company.

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 each Fund's assets will not be
considered a violation of the restriction.

THOSE RESPONSIBLE FOR MANAGEMENT

The  business  of the Fund is  managed  by its  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
Trustees of the Fund are also  officers and Directors of the Adviser or officers
and Directors of John Hancock Funds, Inc. ("John Hancock Funds").

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 & 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
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 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 of the daily
net assets of the Fund as follows:

                             Net Asset Value                       Annual Rate
                             ---------------                       -----------
                             First $500,000,000                    0.55%
                             Next $500,000,000                     0.50%
                             Amount over $1,000,000,000            0.45%


                                       24

<PAGE>

The Adviser may  voluntarily  and  temporarily  reduce its  advisory fee or make
other  arrangements  to limit the Fund's  expenses to a specified  percentage of
average  daily net  assets.  The  Adviser  retains  the right to  re-impose  the
advisory 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.

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
respective  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 to the Fund or its
shareholders  for any  error  of  judgment  or  mistake  of law or for any  loss
suffered  by the Fund in  connection  with the  matters  to which  its  Advisory
Agreement relates,  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 its reckless  disregard of its 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 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.

For the fiscal year ended  December  31, 1995 and the period  ending  August 31,
1996,  advisory fees payable to the Fund's  Adviser  amounted to $1,048,120  and
$1,489,530  respectively.  For the fiscal year ended August 31,  1997,  advisory
fees payable to the Fund's Adviser amounted to $4,110,920. However, a portion of
such fees were not imposed  pursuant to the  voluntary fee reduction and expense
limitation  agreement then in effect. For the fiscal year ended August 31, 1998,
advisory fees payable to the Fund's adviser amounted to $ .

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 year ended August 31, 1996, the Fund paid the
Adviser  $20,551 for services  under this  agreement  from the effective date of
July 1, 1996. For the fiscal years ended August 31, 1997 and 1998, the Fund paid
the Adviser $143,283 and $ , respectively, for services under this Agreement.

In order to avoid conflicts with portfolio trades for the Funds, the Adviser and
the Trust have adopted extensive  restrictions on personal securities trading by
personnel of the Adviser and its  affiliates.  Some of these  restrictions  are:
pre-  clearance  for all  personal  trades and a ban on the  purchase of initial
public offerings,  as well as contributions to specified charities of profits on
securities held for less than 91 days. These  restrictions are a continuation of
the basic principle that the interests of the Funds and their  shareholders come
first.

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 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.  John Hancock  Funds accept 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 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 for the period  from  January 1, 1996 to August 31, 1996 and
for the years ended  August 31, 1997 and 1998 were  $364,353,  $642,722  and $ ,
respectively. Of such amounts $39,275, $65,428 and $ , respectively, retained by
John Hancock Funds in 1996,  1997 and 1998.  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 0.25% for Class A shares  and 1.00% for Class B
shares,  of the Fund's average daily net assets  attributable  to shares of that
class.  John  Hancock  Funds has agreed to  continue  to limit the  payments  of
expenses  under the Plans to 0.15% and 0.90% of the average  daily net assets of
the Class A and Class B shares, respectively.  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 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 under the Class A Plan, these expenses
will not be  carried  beyond  twelve  months  from the date they were  incurred.
Unreimbursed  expense  under the Class B Plan 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 Plan as a liability of the Fund
because the Trustees may terminate Class B Plan at any time. For the fiscal year
ended  August 31, 1998 an aggregate  of $ of  distribution  expenses or % of the
average  net  assets of the Class B shares of the Fund,  was not  reimbursed  or
recovered by John Hancock Funds through the receipt of deferred sales charges or
Rule 12b-1 fees in prior periods.
    
                                       27

The Plans were approved by a majority of the voting  securities of the Fund. 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 provides 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 must 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 must 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, in any event, be effective unless it is
approved  by a vote of a  majority  vote  of the  Trustees  and the  Independent
Trustees of the Fund.  The holders of Class A and Class B 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 the 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 each Fund in
proportion to the relative net asset value of the participating Funds.

   
During the fiscal year ended August 31, 1998,  the Fund paid John Hancock  Funds
the following amounts of expenses in connection with their services.

SALES COMPENSATION

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

Compensation  payments  originate from two sources:  from sales charges and from
12b-1 fees that are paid out of the funds'  assets.  The sales charges and 12b-1
fees  paid  by  investors  are  detailed  in  the   prospectus   and  under  the
"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 either a reallowance from the initial sales charge or a commission,  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 net
assets. This fee is paid quarterly in arrears.

Financial  services firms selling large amounts of fund shares may receive extra
compensation.  This  compensation,  which John Hancock Funds pays out of its own
resources,  may  include  asset  retention  fees as well  as  reimbursement  for
marketing expenses.

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.

                                       29

<PAGE>

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 p.m.  Eastern Time)
by dividing a class's net assets by the number of its shares outstanding.

INITIAL SALES CHARGE ON CLASS A 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  reserves the right to change or
waive the 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 shares of the Fund are
described in the Fund's  Prospectus.  Methods of obtaining 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 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.
    

Without Sales Charge.  Class A shares may be offered  without a front-end  sales

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

                  Amounts of $10 million and over               0.25% 
                                                              

Class A 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).   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 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.

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.
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  invested  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 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 Fund to sell,  any  additional  Class A shares and may be  terminated at any
time.

DEFERRED SALES CHARGE ON CLASS B SHARES

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

   
Contingent  Deferred Sales Charge.  Class B shares which are redeemed within six
years of purchase will be subject to a contingent deferred sales charge ("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
shares being  redeemed.  No CDSC will be imposed on  increases in account  value
above  the  initial   purchase   prices,   including  all  shares  derived  from
reinvestment of dividends or capital gains distributions.
    

                                       32

<PAGE>

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  purchases  of 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  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 this  purpose,  the amount of any
increase in a share's value above its initial  purchase price is not regarded as
a share exempt from 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  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)
     oMinus 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 lot 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 shares,  such as the payment of  compensation  to select Selling Brokers
for selling Class B shares. The combination of the CDSC and the distribution and
service  fees  facilitates  the  ability  of the Fund to sell the Class B 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. 

                                       35

<PAGE>

Any such securities would be valued for the purposes of making such payment at
the same value as used in determining 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 PROGRAM

   
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  transaction  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 Short-Term Strategic Income Fund
and John Hancock Intermediate Maturity 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
(except John Hancock Short-Term Strategic Income Fund) 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 Class A or
Class B 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 shares  and  because  redemptions  are
taxable events. Therefore, a shareholder should not purchase Class A and Class B
shares at the same time 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.

                                       36

<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 investments 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 or 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 the Fund or 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 any 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).

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,  without
further action by  shareholders.  As of the date of this Statement of Additional
Information,  the  Trustees  have  authorized  shares  of the Fund and one other
series.  Additional series may be added in the future.  The Declaration of Trust
also  authorizes the Trustees to classify and reclassify the shares of the Fund,
or any new series of the Trust into one or more classes.  The Trustees have also
authorized  the  issuance  of two classes of shares of the Fund,  designated  as
Class A and Class B.
    

The shares of each class of the Fund represent an equal  proportionate  interest
in the aggregate net assets  attributable to that class of the Fund.  Holders of
Class A and Class B 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 Class A and Class B shares will be
borne exclusively by that class (ii) Class B shares will pay higher distribution
and  service  fees than  Class A shares  and  (iii)  each of Class A and Class B
shares will bear any other class  expenses  properly  allocable to that class of
shares,  subject to the conditions  the Internal  Revenue  Service  imposes with
respect to multiple-class  structures.  Similarly, the net asset value per share
may vary depending on whether Class A or Class B 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 class 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.
Fund  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  held  personally
liable by reason of being or having been a shareholder.

                                       38

<PAGE>

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 Fund 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
loss 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.

TAX STATUS

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,  if any) 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.

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.  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.

                                       39

<PAGE>

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 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
funds 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
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.
    
                                       40

<PAGE>

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  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
portfolio  securities  or enter into options or futures  transactions  that will
generate capital gains. At the time of an investor's  purchase of Fund 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
Class A shares  of the 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 disallowed amount,  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.

                                       41

<PAGE>

Although the Fund's 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 net capital  gains,  if any,  during the
eight years following the year of the loss. To the extent subsequent net 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 as such to
shareholders.   The  Fund  has   $15,619,534  of  capital  loss   carryforwards,
$10,378,466  expires in 2002,  $5,155,633 expires in 2003 and $85,435 expires in
2004 which are available to offset future net capital gains.

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

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.  These and other issues
will be addressed by the Fund,  in the event it invests in such  securities,  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.

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  sales 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.

                                       42

<PAGE>

The  Federal  income  tax rules  applicable  to  certain  structured  or indexed
securities,  interest rates swaps, caps, floors and collars,  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.

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  gains  (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  portfolio  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.

A state  income (and  possibly  local income  and/or  intangible  property)  tax
exemption is generally available to the extent (if any) the Fund's distributions
are derived from interest on (or, in the case of intangibles property taxes, the
value of its assets is attributable to) certain U.S.  Government  obligations or
municipal  obligations of issuers in the state in which a shareholder is subject
to tax,  provided in some states that  certain  thresholds  for holdings of such
obligations and/or reporting requirements are satisfied.  The Fund will not seek
to satisfy any threshold or reporting  requirements that may apply in particular
taxing  jurisdictions,  although  the Fund may in its  sole  discretion  provide
relevant information to shareholders.

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.
The discussion does not address special tax rules  applicable to certain types
of investors, such as insurance companies and financial institutions.  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.  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  that is  different  from  that  described  above.  These
investors may be subject to nonresident 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 or  authorized
substitute  for Form W-8 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.

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.

CALCULATION OF PERFORMANCE

   
For the 30-day period ended August 31, 1998, the annualized yields of the Fund's
Class A and Class B shares were % and %, respectively.  The average annual total
returns of the Class A shares of the Fund for the one and five year  periods and
since  inception on January 5, 1990 were %, % and %,  respectively ( %, % and %,
respectively, without taking into account the expense limitation arrangements).

As of August 31, 1998,  the average annual returns for the Fund's Class B shares
for the one and five year periods and since  inception on December 31, 1991 were
%, % % and %,  respectively  ( %, % and %,  respectively,  without  taking  into
account the expense limitation arrangements).

Total return is computed by finding the average annual compounded rate of return
over the 1-year,  5-year,  and  10-year  periods  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.

                                       44

<PAGE>

Because each share has its own sales charge and fee structure,  the classes have
different  performance  results.  In the case of Class A or Class B shares, this
calculation  assumes  the  maximum  sales  charge  is  included  in the  initial
investment  or the CDSC is applied at the end of the  period.  This  calculation
also 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 maximum sales charge on Class A
shares or the CDSC on Class B shares into  account.  Excluding  the Fund's sales
charge  on Class A shares  and the  CDSC on Class B 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 of 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.

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 = ( [ (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).

                                       45

<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 a maximum  federal tax rate for the 30-day  period ended
August 31, 1998 were % and %, respectively.
    

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 the Russell and Wilshire Indices.

Performance  rankings and ratings  reported  periodically in national  financial
publications  such as MONEY  Magazine,  FORBES,  BUSINESS  WEEK, THE WALL STREET
JOURNAL, MICROPAL, INC., MORNINGSTAR,  STANGER'S and BARRON'S, etc. will 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 nd  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 such 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 other  policies  that 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.

                                       46

<PAGE>

   
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
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  commitments  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, their policies and practices in
this  regard  must be  consistent  with the  foregoing  and will at all times be
subject to review by the  Trustees.  For the period ended  August 31, 1996,  the
Fund paid negotiated  brokerage  commissions in the amount of $335,052.  For the
fiscal years ended August 31, 1997 and 1998, the Fund paid negotiated  brokerage
commissions in the amount of $820,093 and $ , respectively.

As permitted by Section 28(e) of the  Securities  Exchange Act of 1934, the Fund
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 periods ended August 31, 1996, 1997 and
1998,  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  John Hancock  Distributors,  Inc., a broker dealer  ("John  Hancock
Distributors" 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  Affiliated  Brokers.
During the period ended August 31, 1996, 1997 and 1998, the Fund did not execute
any portfolio transaction with Affiliated Brokers.
    

Distributors 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 a 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  Brokers.  Because the Adviser,
which is affiliated with the Affiliated  Brokers,  has, as an investment adviser
to the Fund, 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  Brokers  as a basis  for
negotiating commissions at a rate higher than that determined in accordance with
the above criteria.

                                       47

<PAGE>

Other investment  advisory clients advised by the Adviser may also invest in the
same securities and 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.  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 of the Fund. The Fund pays Signature Services
an annual fee of $20.00 for each Class A shareholder account and $22.50 for each
Class B shareholder account, plus certain out-of-pocket expenses. These expenses
are  aggregated and charged to the Fund and allocated to each class 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,  Massachusetts  02116. Under the custodian  agreement,  Investors Bank &
Trust Company performs custody, portfolio and fund accounting services.

                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).

                                      A-1

<PAGE>

                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.

                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).

                  TAX EXEMPT BOND RATINGS

                  Below is a  description  of the six ratings  that may apply to
                  the Fund's investments in tax-exempt Bonds.

                  tax-exempt Bond Ratings

                  Mode's  describes  its six  highest  ratings  for  Tax-exempt 
                  Bonds as follows:

                  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  greater  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  some  time  in the
                  future.

                  Bonds  which  are  rated Be 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 a
                  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.


                                      B-1

<PAGE>

                  The six highest  ratings of  Standard & Pool's for  Tax-exempt
                  Bonds are AAA (Prime),  AA (High Grade),  A (Good Grade),  BBB
                  (Medium Grade), BB and B:

          AAA     This is the highest  rating  assigned by Standard & Pool's
                  to  a  debt  obligation  and  indicates  an  extremely  strong
                  capacity to pay principal and interest.

          AA       Bonds  rated  AA  also   qualify  as   high-quality   debt
                  obligations.  Capacity to pay  principal  and interest is very
                  strong,  and in the majority of instances they differ from AAA
                  issues only in small degree.

          A       Bonds rated A have a strong  capacity to pay  principal  and
                  interest,  although they are somewhat more  susceptible to the
                  adverse  effects  of  changes in  circumstances  and  economic
                  conditions.

         BBB      Bonds  rated  BBB are  regarded  as  having  an  adequate
                  capacity to pay principal and interest.  Whereas they normally
                  exhibit protection parameters,  adverse economic conditions or
                  changing  circumstances  are more likely to lead to a weakened
                  capacity  to pay  principal  and  interest  for  bonds in this
                  category than for bonds in the A category.

         BB       Debt rated BB has less near-term  vulnerability  to default
                  than other speculative issues. However, it faces major ongoing
                  uncertainties or exposure to adverse business,  financial,  or
                  economic conditions which could lead to inadequate capacity to
                  meet timely  interest and  principal  payments.  The BB rating
                  category  is also used for debt  subordinated  to senior  debt
                  that is assigned an actual or implied BBB rating.

         B        Debt  rated B has a greater  vulnerability  to  default  but
                  currently  has the  capacity  to meet  interest  payments  and
                  principal repayments. Adverse business, financial, or economic
                  conditions  will likely impair  capacity or willingness to pay
                  interest and repay  principal.  The B rating  category is also
                  used for debt  subordinated to senior debt that is assigned an
                  actual or implied BB or BB rating.


                  Fitch describes its ratings 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.


                                      B-2

<PAGE>

         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
         "AA"     categories are not  significantly  vulnerable to foresee
                  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  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.

         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  that could assist the obligor
                  in satisfying its debt service requirements.

         B        Bonds are considered highly speculative. While bonds in this
                  class are  currently  meeting debt service  requirements,  the
                  probability  of  continued  timely  payment of  principal  and
                  interest  reflects the obligor's  limited margin of safety and
                  the  need  for  reasonable   business  and  economic  activity
                  throughout the life of the issue.

                Mode's   ratings  for  state  and  municipal   notes  and  other
                short-term loans are designated Mode's Investment Grade (MIDGE).
                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  in bond risk are of lesser  importance in the short-
                term run. Symbols used will be as follows:

                MIDGE 1 Loans 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.

                MIDGE 2 Loans bearing this designation are of high quality, with
                margins  of  protection  ample  although  not so large as in the
                preceding group.


                                      B-3

<PAGE>


                MIDGE 3 Loans bearing this designation are of favorable quality,
                with all  securities  elements  accounted  for but  lacking  the
                undeniable  strength of the preceding grades.  Market access for
                refinancing,   in   particular,   is  likely  to  be  less  well
                established.

                Standard  & Pool's  ratings  for state and  municipal  notes and
                other  short-term  loans are designated  Standard & Pool's Grade
                (SP).

                SP-1  Very  strong  or  strong  capacity  to pay  principal  and
                interest. Those issues determined to possess overwhelming safety
                characteristics will be given a plus (+) designation.

                       SP-2 Satisfactory capacity to pay principal and interest.

                       SP-3 Speculative capacity to pay principal and interest.

                Fitch Ratings for short-term debt  obligations  that are payable
                on  demand  or have  original  maturates  of up to  three  years
                including  commercial  paper,  certificates of deposits,  medium
                term notes and municipal and investment  notes are designated by
                the following ratings:

                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+.

                F-2 Good  Credit  Quality.  Issues  assigned  this rating have a
                satisfactory  degree of assurance  for timely  payment,  but the
                margin for safety is not as great as for  issues  assigned  F-1+
                and F-1 ratings.

                F-S Weak  Credit  Quality.  Issues  assigned  this  rating  have
                characteristics  suggesting a minimal  degree of  assurance  for
                timely payment and are vulnerable to near-term  adverse  changes
                in financial and economic conditions.

It is  assumed  that an  investor  filing  a  single  return  is not a "head  of
household,"  a "married  individual  filing a separate  return," or a "surviving
spouse." The table does not take into account the effects of  reductions  in the
deductibility of itemized deductions or the phase out of personal exemptions for
taxpayers with adjusted gross incomes in excess of specified  amounts.  Further,
the table does not attempt to show any  alternative  minimum  tax  consequences,
which will depend on each  shareholder's  particular  tax situation and may vary
according to what portion,  it any, of the Fund's  exempt-interest  dividends is
attributable  to interest on certain  private  activity bonds for any particular
taxable  year. No assurance can be given that the Fund will achieve any specific
tax-exempt  yield or that all of its income  distributions  will be  tax-exempt.
Distributions  attributable  to any taxable  income or capital gains realized by
the Fund will not be tax-exempt.

The  information  set  forth  above  is as of the  date  of  this  Statement  of
Additional  Information.  Subsequent tax law changes could result in prospective
or retroactive changes in the tax brackets, tax rates, and tax-equivalent yields
set forth above.

This table is for  illustrative  purposes  only and is not  intended to imply or
guarantee  any  particular  yield  from the Fund.  While it is  expected  that a
substantial   portion  of  the  interest   income   distributed  to  the  Fund's
shareholders  will  be  exempt  from  federal  income  taxes,  portions  of such
distributions from time to time may be subject to federal income taxes.

Item 24.   Persons Controlled by or under Common Control with Registrant.

No person is directly or indirectly  controlled by or under common  control with
Registrant.

Item. 25.  Indemnification.

Indemnification  provisions  relating to the  Registrant's  Trustees,  officers,
employees  and agents is set forth in Article  VII of the  Registrant's  By Laws
included as Exhibit 2 herein.

Under Section 12 of the Distribution Agreement,  John Hancock Funds, Inc. ("John
Hancock  Funds")  has  agreed to  indemnify  the  Registrant  and its  Trustees,
officers and controlling  persons against claims arising out of certain acts and
statements of John Hancock Funds.

Section 9(a) of the By-Laws of John Hancock Mutual Life Insurance  Company ("the
Insurance  Company")  provides,  in effect,  that the  Insurance  Company  will,
subject to  limitations  of law,  indemnify  each  present and former  director,
officer and employee of the Insurance Company who serves as a Trustee or officer
of the Registrant at the direction or request of the Insurance  Company  against
litigation  expenses and liabilities  incurred while acting as such, except that
such indemnification does not cover any expense or liability incurred or imposed
in  connection  with  any  matter  as to which  such  person  shall  be  finally
adjudicated  not to have acted in good faith in the  reasonable  belief that his
action was in the best interests of the Insurance Company. In addition,  no such
person  will be  indemnified  by the  Insurance  Company in respect of any final
adjudication  unless  such  settlement  shall have been  approved as in the best
interests of the Insurance Company either by vote of the Board of Directors at a
meeting  composed of directors who have no interest in the outcome of such vote,
or by vote of the policyholders. The Insurance Company may pay expenses incurred
in  defending an action or claim in advance of its final  disposition,  but only
upon receipt of an undertaking  by the person  indemnified to repay such payment
if he should be determined not to be entitled to indemnification.

Article IX of the  respective  By-Laws of John  Hancock  Funds and John  Hancock
Advisers, Inc. ("the Adviser") provide as follows:

"Section  9.01.  Indemnity.  Any person made or threatened to be made a party to
any action,  suit or proceeding,  whether  civil,  criminal,  administrative  or
investigative,  by reason  of the fact  that he is or was at any time  since the
inception  of the  Corporation  a  director,  officer,  employee or agent of the

                                      C-1

<PAGE>

Corporation  or is or was at any time  since the  inception  of the  Corporation
serving at the request of the  Corporation as a director,  officer,  employee or
agent  of  another  corporation,  partnership,  joint  venture,  trust  or other
enterprise,  shall be indemnified by the Corporation against expenses (including
attorney's fees),  judgments,  fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding if
he acted in good faith and the  liability  was not  incurred  by reason of gross
negligence  or reckless  disregard of the duties  involved in the conduct of his
office, and expenses in connection therewith may be advanced by the Corporation,
all to the full extent authorized by the law."

"Section 9.02. Not Exclusive;  Survival of Rights: The indemnification  provided
by Section 9.01 shall not be deemed  exclusive of any other right to which those
indemnified may be entitled, and shall continue as to a person who has ceased to
be a director,  officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person."

Insofar as indemnification for liabilities under the Securities Act of 1933 (the
"Act") may be  permitted to Trustees,  officers and  controlling  persons of the
Registrant pursuant to the Registrant's Declaration of Trust and By-Laws of John
Hancock  Funds,  the  Adviser,  or  the  Insurance  Company  or  otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission  such  indemnification  is against policy as expressed in the Act and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against  such  liabilities  (other  than the  payment by the  Registrant  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
Trustee,  officer or controlling  person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether indemnification by it is against public policy
as expressed in the Act and will be governed by the final  adjudication  of such
issue.

Item 26.  Business and Other Connections of Investment Advisers.

For  information  as to the  business,  profession,  vocation or employment of a
substantial  nature  of each  of the  officers  and  Directors  of the  Adviser,
reference is made to Form ADV (801-8124) filed under the Investment Advisers Act
of 1940, which is incorporated herein by reference.

Item 27.  Principal Underwriters.

serves as principal  underwriter  or distributor of shares for John Hancock Cash

               (ii)Pursuant to purchase orders, issue the appropriate number

               account;

               (iii)Receive for acceptance,  redemption  requests and redemption

               (vi)Prepare and transmit payments for dividends and distributions

               the Fund next computed after the payment (in accordance  with the
               Fund's then-current prospectus);

               (vii)Maintain  records of account for and advise the Fund and its

               Shares of the Fund which are authorized, based upon data provided
               to it by the Fund,  and issued and  outstanding.  JHSS shall also
               provide the Fund,  on a regular  basis,  with the total number of
               Shares which are authorized and issued and  outstanding and shall
               have no  obligation,  when  recording the issuance of Shares,  to
               monitor the issuance of these Shares or to take cognizance of any
               laws  relating  to the  issue  or sale  of  these  Shares,  which
               functions shall be the sole responsibility of the Fund.

         (b) In  calculating  the number of Shares to be issued on  purchase  or
         reinvestment, or redeemed or repurchased, or the amount of the purchase
         payment or redemption or repurchase  payments owed,  JHSS shall use the
         net asset  value per share (as  described  in the  Fund's  then-current
         prospectus) computed by it or such other person as may be designated by
         the Fund's Board.  All  issuances,  redemptions  or  repurchases of the
         Funds'  shares  shall be  effected  at net asset  values per share next
         computed  after  receipt of the orders  therefore and said orders shall
         become irrevocable at the time as of which said value is next computed.

         (c) In  addition  to and not in lieu of the  services  set forth in the
         above  paragraph  (a),  JHSS shall:  (i)  perform all of the  customary
         services of a transfer agent and dividend  disbursing  agent  including

         Shareholders,  preparing and mailing  confirmation forms and statements
         of account to Shareholders  for all purchases and redemptions of Shares
         and other confirmable  transactions in Shareholder accounts,  preparing
         and  mailing  activity  statements  for  Shareholders,   and  providing

<PAGE>

         Shareholder  account  information  and (ii) provide a system which will
         enable the Fund to monitor the total  number of the Fund's  Shares sold
         in each State.

         (d) In addition,  the Fund shall (i) identify to JHSS in writing  those
         transactions  and  assets to be  treated  as  exempt  from the blue sky
         reporting  for  each  State  and  (ii)  verify  the   establishment  of
         transactions  for each  State on the  system  prior to  activation  and
         thereafter   monitor   the  daily   activity   for  each   State.   The
         responsibility  of JHSS  for the  Fund's  blue sky  State  registration
         status is solely limited to the initial  establishment  of transactions
         subject to blue sky  compliance  by the Fund and the reporting of these
         transactions to the Fund as provided above.

         (e) Additionally, JHSS shall:

               (i) Utilize a system to  identify  all share  transactions  which
               involve  purchase and  redemption  orders that are processed at a
               time other than the time of the  computation  of net asset  value
               per share next computed  after receipt of such orders,  and shall
               compute  the net  effect  upon  the Fund of the  transactions  so
               identified on a daily and cumulative basis.

               (ii)  If  upon  any  day  the   cumulative  net  effect  of  such
               transactions  upon  the Fund is  negative  and  exceeds  a dollar
               amount equivalent to 1/2 of 1 cent per share, JHSS shall promptly
               make a payment to the Fund in cash or through the use of a credit
               in the manner  described in paragraph (iv) below,  in such amount
               as may be necessary to reduce the negative  cumulative net effect
               to less than 1/2 of 1 cent per share.

               (iii) If on the last business day of any month the cumulative net
               effect upon the Fund of such transactions (adjusted by the amount
               of all  prior  payments  and  credits  by JHSS  and the  Fund) is
               negative,  the Fund shall be entitled  to a reduction  in the fee
               next payable under the Agreement by an equivalent amount,  except
               as provided in paragraph (iv) below.  If on the last business day
               in any  month the  cumulative  net  effect  upon the Fund of such
               transactions  (adjusted  by the amount of all prior  payments and
               credits by JHSS and the Fund) is positive, JHSS shall be entitled
               to recover certain past payments and reductions in fees, and to a
               credit against all future payments and fee reductions that may be
               required  under the  Agreement  as herein  described in paragraph
               (iv) below.

               (iv) At the end of each month, any positive cumulative net effect
               upon a Fund of such  transactions  shall be deemed to be a credit
               to JHSS which  shall  first be applied to permit  JHSS to recover
               any prior cash payments and fee reductions made by it to the Fund
               under  paragraphs  (ii) and (iii) above during the calendar year,
               by  increasing  the amount of the monthly fee under the Agreement
               next  payable  in an  amount  equal  to  prior  payments  and fee
               reductions  made by  JHSS  during  such  calendar  year,  but not
               exceeding the sum of that month's  credit and credits  arising in
               prior months  during such  calendar year to the extent such prior
               credits have not previously been utilized as contemplated by this
               paragraph.  Any  portion  of a  credit  to JHSS not so used by it
               shall remain as a credit to be used as payment against the amount
               of  any  future  negative   cumulative  net  effects  that  would
               otherwise  require a cash payment or fee  reduction to be made to
               the Fund pursuant to paragraphs  (ii) or (iii) above  (regardless
               of whether or not the credit or any portion  thereof arose in the
               same calendar year as that in which the negative  cumulative  net
               effects or any portion thereof arose).
 
                                        3
<PAGE>

                  (v) JHSS  shall  supply  to the  Fund  from  time to time,  as
                  mutually agreed upon,  reports  summarizing  the  transactions
                  identified  pursuant to paragraph (i) above, and the daily and
                  cumulative net effects of such transactions,  and shall advise
                  the Fund at the end of each month of the net cumulative effect
                  at such time.  JHSS shall  promptly  advise the Fund if at any
                  time the  cumulative  net  effects  exceeds  a  dollar  amount
                  equivalent to 1/2 of 1 cent per share.

                  (vi) In the  event  that  this  Agreement  is  terminated  for
                  whatever  cause,  or this  provision  2.02  (d) is  terminated
                  pursuant to paragraph (vii) below, the Fund shall promptly pay
                  to JHSS an  amount  in cash  equal to the  amount by which the
                  cumulative  net effect  upon the Fund is  positive  or, if the
                  cumulative  net effect upon the Fund is  negative,  JHSS shall
                  promptly pay to the Fund an amount in cash equal to the amount
                  of such cumulative net effect.

                  (vii)  This  provision  2.02  (e)  of  the  Agreement  may  be
                  terminated by JHSS at any time without cause,  effective as of
                  the close of business on the date written notice (which may be
                  by telex) is received by the Fund.

to time by agreement between the Fund and JHSS.

7.03 JHSS shall keep records relating to the services to be performed hereunder,
in the form and  manner as it may deem  advisable.  To the  extent  required  by

of the Securities and Exchange Commission thereunder,  JHSS agrees that all such
records  prepared or maintained by JHSS relating to the services to be performed
by JHSS hereunder are the property of the Fund and will be preserved, maintained
and  made  available  in  accordance  with  such  Act  and  rules,  and  will be
surrendered to the Fund promptly on and in accordance with the Fund's request.

7.04 JHSS and the Fund  agree  that all  books,  records,  information  and data
pertaining  to the  business of the other party which are  exchanged or received

confidential, and shall not be voluntarily disclosed to any other person without
the consent of the other party to this  Agreement,  except as may be required by

JHSS will make reports to the Fund, as requested,  of JHSS's  performance of the
foregoing services.

necessary for the preparation of registration statements and periodic reports to
be filed with the Securities  and Exchange  Commission,  including  registration
statements on Form N-1A, semi-annual reports on Form N-SAR, periodic statements,
shareholder communications and proxy materials furnished to holders of shares of
the Fund,  filings with state "blue sky"  authorities and with United States and
foreign agencies  responsible for tax matters,  and other reports and filings of
like nature.

7.07 In case of any requests or demands for the  inspection  of the  Shareholder
records  of the  Fund,  JHSS  will  endeavor  to  notify  the Fund and to secure
instructions from an authorized officer of the Fund as to such inspection.  JHSS
reserves the right,  however,  to exhibit the Shareholder  records to any person
whenever it is advised by its counsel that it may be held liable for the failure
to exhibit the Shareholder records to such person.

expenses associated with such termination.


Article 10          Assignment

10.03 JHSS may, without further consent on the part of the Fund, subcontract for

17A(c)(1)")  or any other entity  registered  as a transfer  agent under Section

conditions of this  Agreement;  provided,  however,  that JHSS shall be as fully
responsible to the Fund for the acts and omissions of any subcontractor as it is
for its own acts and omissions.


Article 11          Amendment

11.01 This Agreement may be amended or modified by a written agreement  executed
by both parties and  authorized  or approved by a resolution  of the Trustees of
the Trust or Directors of the Corporation.

Article 14            Limitation on Liability

14.01 If the Fund is a Massachusetts business trust, JHSS expressly acknowledges

of the trustees and shareholders of the Fund; and JHSS agrees that it shall have
recourse only to the assets of the Fund for the payment of claims or obligations
as between JHSS and the Fund arising out of this  Agreement,  and JHSS shall not
seek  satisfaction  of any  such  claim  or  obligation  from  the  trustees  or
shareholders  of the Fund. In any case,  each Fund, and each series or portfolio
of each Fund,  shall be liable only for its own  obligations  to JHSS under this
Agreement and shall not be jointly or severally  liable for the  obligations  of
any other Fund, series or portfolio hereunder.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed
in their names and on their behalf  under their seals by and through  their duly
authorized officers, as of the day and year first above written.

                               John Hancock Funds

                               Class A and Class B

                   Multiple Class Plan Pursuant to Rule 18f-3

Each  class of shares of each of the John  Hancock  Funds  listed in  Appendix A
attached  hereto  (each the  "Fund")  will  have the same  relative  rights  and
privileges and be subject to the same sales charges,  fees and expenses,  except
as set forth  below.  The Board of  Trustees/Directors,  as the case may be, may
determine in the future that other  allocations of expenses (whether ordinary or
extraordinary)  or  other  services  to be  provided  to a class of  shares  are
appropriate and amend this Plan accordingly without the approval of shareholders
of any  class.  Except  as set forth in the  Fund's  prospectus,  shares  may be
exchanged  only for shares of the same class of another fund in the John Hancock
group of funds.

Class A Shares

Class A Shares  are sold at net asset  value and  subject to the  initial  sales
charge  schedule or contingent  deferred  sales charge and the minimum  purchase
requirements set forth in the Fund's  prospectus.  Class A Shares are subject to
fees under the  Fund's  Class A Rule  12b-1  Distribution  Plan on the terms set
forth in the Fund's  prospectus.  The Class A Shareholders have exclusive voting
rights,  if any, with respect to the Class A Distribution  Plan.  Class A Shares
shall be entitled to the shareholder services set forth from time to time in the
Fund's prospectus with respect to Class A Shares.

Class B Shares

Class B Shares are sold at net asset value per share  without the  imposition of
an initial sales charge.  However,  Class B shares  redeemed  within a specified
number of years of  purchase  will be subject  to a  contingent  deferred  sales
charge as set forth in the Fund's prospectus. Class B Shares are sold subject to
the minimum purchase  requirements set forth in the Fund's  prospectus.  Class B
Shares are subject to fees under the Class B Rule 12b-1 Distribution Plan on the
terms set forth in the Fund's  prospectus.  The Class B Shareholders of the Fund
have  exclusive  voting  rights,  if any,  with  respect to the  Fund's  Class B
Distribution Plan. Class B Shares shall be entitled to the shareholder  services
set forth from time to time in the  Fund's  prospectus  with  respect to Class B
Shares.

Class B Shares will  automatically  convert to Class A Shares of the Fund at the
end of a specified  number of years after the initial  purchase  date of Class B
shares,  except as provided in the Fund's prospectus.  The initial purchase date
for Class B shares acquired through  reinvestment of dividends on Class B Shares
will be  deemed  to be the  date on  which  the  original  Class B  shares  were
purchased.  Such conversion will occur at the relative net asset value per share
of each class.  Redemption  requests placed by shareholders who own both Class A
and  Class B Shares  of the  Fund  will be  satisfied  first  by  redeeming  the
shareholder's  Class A  Shares,  unless  the  shareholder  has  made a  specific
election to redeem Class B Shares.

The  conversion  of Class B Shares to Class A Shares may be  suspended  if it is
determined that the conversion  constitutes or is likely to constitute a taxable
event under federal income tax law.
