Overview

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

FUND INFORMATION KEY

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

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

[Clip Art] Portfolio securities 
The primary types of securities in which the fund invests. Secondary investments
are described in "More about risk" at the end of the prospectus.

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

[Clip Art] Portfolio management 
The individual or group designated by the investment adviser to handle the
fund's day-to-day management.

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

[Clip Art] Financial highlights 
A table showing the fund's financial performance for up to ten years, by share
class. A bar chart showing total return allows you to compare the fund's
historical risk level to those of other funds.

GOAL OF THE INCOME FUNDS

John Hancock income funds seek current income without sacrificing total return.
Some of the funds also invest for stability of principal. Each fund has its own
strategy and its own risk/reward profile. Because you could lose money by
investing in these funds, be sure to read all risk disclosure carefully before
investing.

WHO MAY WANT TO INVEST

These funds may be appropriate for investors who:

o   are seeking a regular stream of income
o   are seeking higher potential returns than money market funds and are willing
    to accept moderate risk of volatility
o   want to diversify their portfolios
o   are seeking a mutual fund for the income portion of an asset allocation 
    portfolio
o   are retired or nearing retirement

Income funds may NOT be appropriate if you:

o   are investing for maximum return over a long time horizon
o   require absolute stability of your principal

THE MANAGEMENT FIRM

   
All John Hancock 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 $26 billion in assets.

Government Income Fund

REGISTRANT NAME: 
JOHN HANCOCK BOND TRUST    TICKER SYMBOL     CLASS A: JHGIX       CLASS B: TSGIX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip Art] The fund seeks to earn a high level of current income consistent with
preservation of capital. To pursue this goal, the fund invests primarily in U.S.
Government and agency securities of any maturity, as described below. Stability
of share price is a secondary goal.

PORTFOLIO SECURITIES

[Clip Art] Under normal circumstances, the fund invests at least 80% of assets
in securities that are issued, or guaranteed as to principal and interest, by
the U.S. Government, its agencies or instrumentalities. These may include
Treasuries, mortgage-backed securities such as Ginnie Maes, Freddie Macs and
Fannie Maes, and repurchase agreements and forward commitments involving these
securities.

For liquidity and flexibility, the fund may place up to 20% of assets in
high-quality short-term securities. In abnormal market conditions, it may invest
more assets in these securities as a defensive tactic. The fund also may invest
in certain higher-risk investments, including asset-backed securities, U.S.
dollar-denominated foreign government securities and derivative and leveraged
investments, and may engage in other investment practices. Investments in
asset-backed and foreign government securities must be in the two highest and
four highest rating categories, respectively, or if unrated, be of comparable
quality. Up to 10% of assets may be invested in foreign government bonds rated
BB/Ba or B (junk bonds).

RISK FACTORS

[Clip Art] As with most income funds, the value of your investment will
fluctuate with changes in interest rates. Typically, a rise in interest rates
causes a decline in the market value of debt securities (including U.S.
Government and mortgage-backed securities). To the extent that the fund invests
in mortgage-backed securities, it may also be subject to extension and
prepayment risks. These risks are defined in "More about risk" starting on page
27. Other factors may affect the market price and yield of the fund's
securities, including investor demand and domestic and worldwide economic
conditions.

The U.S. Government does not guarantee the market value or the current yield of
government securities, nor does the government's guarantee in any way extend to
the fund itself. Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT

[Clip Art] Barry H. Evans, CFA, leader of the fund's portfolio management team
since January 1995, is a senior vice president of the adviser. He has been in
the investment business since joining John Hancock Funds in 1986.

Example  
The table below shows what you would pay if you invested $1,000 over the various
time frames indicated. The example assumes you reinvested all dividends and that
the average annual return was 5%.

    Assuming no redemption       $19         $59         $102        $200

This example is for comparison purposes only and is not a representation of the
fund's actual expenses and returns, either past or future.

(1)  Except for investments of $1 million or more; see "How sales charges are 
     calculated."
(2)  Does not include wire redemption fee (currently $4.00).
(3)  Because of the 12b-1 fee, long-term shareholders may indirectly
     pay more than the equivalent of the maximum permitted front-end sales 
     charge.

GOAL AND STRATEGY

[Clip Art] The fund seeks to maximize current income without assuming undue
risk. To pursue this goal, the fund invests primarily in junk bonds, i.e.
lower-rated, higher-yielding debt securities. Because the performance of junk
bonds has historically been influenced by economic conditions, the fund may
rotate securities selection by business sector according to the economic
outlook.

The fund also seeks capital appreciation, but only when consistent with its
primary goal.

PORTFOLIO SECURITIES

[Clip Art] Under normal circumstances, the fund invests at least 65% of assets
in bonds rated lower than BBB/Baa and their unrated equivalents. Up to 30% of
assets may be invested in bonds rated CC/Ca. Up to 40% of assets may be invested
in the securities of issuers in the electric utility and telephone industries.
For all other industries, the limitation is 25% of assets.

Types of bonds include, but are not limited to, domestic and foreign corporate
bonds, debentures, notes, convertible securities, preferred stocks, municipal
obligations and government obligations.

The fund may also invest up to 20% of net assets in U.S. or foreign equities.

For liquidity and flexibility, the fund may place up to 35% of assets in
investment-grade short-term securities. In abnormal market conditions, it may
invest more assets in these securities as a defensive tactic. The fund also may
invest in certain higher-risk investments, including restricted securities, and
may engage in other investment practices.

RISK FACTORS

[Clip Art] Investors should expect greater fluctuations in share price, yield
and total return compared with less aggressive bond funds. These fluctuations,
whether positive or negative, may be sharp and unanticipated.

Issuers of junk bonds are typically in weak financial health and their ability
to pay interest and principal is uncertain. Compared with issuers of
investment-grade bonds, they are more likely to encounter financial difficulties
and to be materially affected by these difficulties when they do encounter them.
Junk bond markets may react strongly to adverse news about an issuer or the
economy, or to the perception or expectation of adverse news. Before you invest,
please read "More about risk" starting on page 27.

PORTFOLIO MANAGEMENT

[Clip Art] Arthur N. Calavritinos, CFA, leader of the fund's portfolio
management team since July 1995, is a vice president of the adviser. He joined
John Hancock Funds in 1988 and has been in the investment business since 1987.

GOAL AND STRATEGY

[Clip Art] The fund seeks to earn a high level of current income consistent with
preservation of capital and maintenance of liquidity. To pursue this goal, the
fund invests primarily in U.S. Government securities of any maturity, as
described below. The fund's weighted average maturity will typically be between
three and ten years.

PORTFOLIO SECURITIES

[Clip Art] Under normal circumstances, the fund invests at least 80% of assets
in securities that are issued, or guaranteed as to principal and interest, by
the U.S. Government, its agencies or instrumentalities. These may include
Treasuries and mortgage-backed securities such as Ginnie Maes and Fannie Maes.
The fund may invest up to 20% in asset-backed securities or corporate debt
securities rated AAA/Aaa and their unrated equivalents.

For liquidity and flexibility, the fund may place up to 20% of assets in
high-quality short-term securities. In abnormal market conditions, it may invest
more assets in these securities as a defensive tactic. The fund also may invest
in certain higher-risk investments, including derivative and leveraged
investments, and may engage in other investment practices.

RISK FACTORS

[Clip Art] As with most income funds, the value of your investment will
fluctuate with changes in interest rates. Typically, a rise in interest rates
causes a decline in the market value of debt securities (including U.S.
Government and mortgage-backed securities). To the extent that the fund invests
in mortgage-backed securities, it may also be subject to extension and
prepayment risks. These risks are defined in "More about risk" starting on page
27. Other factors may affect the market price and yield of the fund's
securities, including investor demand and domestic and worldwide economic
conditions.

The U.S. Government does not guarantee the market value or the current yield of
government securities, nor does the government's guarantee in any way extend to
the fund itself. Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT

[Clip Art] Roger C. Hamilton, leader of the fund's portfolio management team
since January 1992 (with the fund's previous adviser), is a vice president of
the adviser. He joined John Hancock Funds in December 1994 and has been in the
investment business since 1980.

Sovereign Bond Fund

REGISTRANT NAME: 
JOHN HANCOCK SOVEREIGN BOND FUND   TICKER SYMBOL   
                                            CLASS A: JHNBX      CLASS B: JHBBX
- -------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip Art] The fund seeks to generate a high level of current income consistent
with prudent investment risk. To pursue this goal, the fund invests in a
diversified portfolio of marketable debt securities. These securities are
primarily investment grade, although up to 25% of assets may be invested in junk
bonds rated as low as CC/Ca and their unrated equivalents. The fund does not
concentrate its investments in any particular industry.

PORTFOLIO SECURITIES

[Clip Art] Under normal circumstances, the fund invests at least 65% of assets
in corporate and government bonds and debentures. Typically, at least 75% of
assets will be: o securities of any type of issuer that are rated among the four
highest Moody's or S&P rating categories and their unrated equivalents o U.S.
Government and agency securities o cash and cash-equivalents

The fund may invest up to 25% of assets in U.S. dollar-denominated foreign
securities.

For liquidity and flexibility, the fund may place up to 35% of assets in
investment-grade short-term securities. In abnormal market conditions, it may
invest more assets in these securities as a defensive tactic. The fund also may
invest in certain higher-risk investments, including asset-backed securities and
derivatives and leveraged investments, and may engage in other investment
practices.

RISK FACTORS

[Clip Art] Investors should expect fluctuations in share price, yield and total
return, particularly with changes in interest rates. Typically, a rise in
interest rates causes a decline in the market value of debt securities. To the
extent that it invests in certain securities, the fund may be affected by
additional risks: o junk bonds: above-average credit, market and other risks o
foreign securities: currency, information, natural event and political risks o
mortgage-backed securities: extension and prepayment risks

These risks are defined in "More about risk" starting on page 27. The longer the
fund's average weighted maturity, the more it is likely to be affected by a
change in interest rates. Please read "More about risk" carefully before
investing.

PORTFOLIO MANAGEMENT

[Clip Art] James K. Ho, CFA, leader of the fund's portfolio management team
since March 1988, is an executive vice president of the adviser. He joined John
Hancock Funds in 1985 and has been in the investment business since 1977.

- --------------------------------------------------------------------------------
INVESTOR EXPENSES

 Total fund operating expenses                          1.11%        1.81%

Example The table below shows what you would pay if you invested $1,000 over the
various time frames indicated. The example assumes you reinvested all dividends
and that the average annual return was 5%.

    at end of period             $69         $87           $118       $194
    Assuming no redemption       $19         $57            $98       $194

This example is for comparison purposes only and is not a representation of the
fund's actual expenses and returns, either past or future.

(1) Except for investments of $1 million or more; see "How sales charges are
    calculated."
(2) Does not include wire redemption fee (currently $4.00).
(3) Because of the 12b-1 fee, long-term shareholders may indirectly pay more
    than the equivalent of the maximum permitted front-end sales charge.

Sovereign U.S. Government Income Fund

REGISTRANT NAME: 
JOHN HANCOCK STRATEGIC SERIES     TICKER SYMBOL          
                                          CLASS A: JHSGX          CLASS B: FGOPX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip Art] The fund seeks to provide as high a level of income as is consistent
with long-term total return. To pursue this goal, the fund invests in U.S.
Government and agency securities, as described below.

PORTFOLIO SECURITIES

[Clip Art] Under normal circumstances, the fund invests at least 65% of assets
in securities that are issued, or guaranteed as to principal and interest, by
the U.S. Government, its agencies or instrumentalities. These may include
Treasuries and mortgage-backed securities such as Ginnie Maes and Fannie Maes.

For liquidity and flexibility, the fund may place up to 35% of assets in
investment-grade short-term securities. In abnormal market conditions, it may
invest more assets in these securities as a defensive tactic. The fund also may
invest in certain higher-risk investments, including derivative and leveraged
investments, and may engage in other investment practices.

RISK FACTORS

[Clip Art] As with most income investments, the value of your investment will
fluctuate with changes in interest rates. Typically, a rise in interest rates
causes a decline in the market value of debt securities (including U.S.
Government and mortgage-backed securities). To the extent that the fund invests
in mortgage-backed securities, it may also be subject to extension and
prepayment risks. These risks are defined in "More about risk" starting on page
27. Other factors may affect the market price and yield of the fund's
securities, including investor demand and economic conditions.

The U.S. Government does not guarantee the market value or the current yield of
government securities, nor does the government's guarantee in any way extend to
the fund itself. Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT

[Clip Art] Barry H. Evans, CFA, leader of the fund's portfolio management team
since January 1995, is a senior vice president of the adviser. He has been in
the investment business since joining John Hancock Funds in 1986.

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

(3) Because of the 12b-1 fee, long-term shareholders may indirectly pay more
    than the equivalent of the maximum permitted front-end sales charge.

GOAL AND STRATEGY

[Clip Art] The fund seeks a high level of current income. To pursue this goal,
the fund invests primarily in three sectors: o foreign government and corporate
debt securities o U.S. Government and agency securities o junk bonds rated as
low as CC/Ca and their unrated equivalents.

Under normal circumstances, the fund's assets will be invested in all three
sectors. However, the weighting of assets among sectors will be adjusted to
reflect current or anticipated market behavior, and the fund may invest up to
100% of assets in any sector.

PORTFOLIO SECURITIES

[Clip Art] The fund may invest in debt securities of all maturities and types,
including bonds, debentures, notes, preferred stock, mortgage-backed and
asset-backed securities and others. The fund may also invest up to 10% of net
assets in U.S. or foreign equities.

For liquidity and flexibility, the fund may invest in investment-grade
short-term securities. In abnormal market conditions, it may invest more assets
in these securities as a defensive tactic. The fund also may invest in certain
higher-risk investments, including derivative and leveraged investments, and may
engage in other investment practices.

RISK FACTORS

[Clip Art] Investors should expect fluctuations in share price, yield and total
return that are above-average for bond funds. Typically, a rise in interest
rates causes a decline in the market value of debt securities. The longer the
fund's average weighted maturity, the more it is likely to be affected by a
change in interest rates. To the extent that the fund invests in mortgage-backed
securities, it may also be subject to extension and prepayment risks. These
risks are defined in "More about risk" starting on page 27. Foreign securities
carry additional risks, including currency, information, natural event and
political risks. Issuers of junk bonds are typically in weak financial health,
and their ability to pay interest and principal is uncertain, especially in an
adverse economy. Junk bond markets may react strongly to adverse news about an
issuer or the economy, or to the perception or expectation of adverse news.
Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT

[Clip Art] Frederick L. Cavanaugh, Jr., leader of the fund's portfolio
management team since 1986, is a senior vice president of the adviser. He joined
John Hancock Funds in 1986 and has been in the investment business since 1973.

INVESTOR EXPENSES

[Clip Art] Fund investors pay various expenses, either directly or indirectly.
The figures below show the expenses for the past year, adjusted to reflect any
changes. Class C expenses are based on Class B expenses as no Class C shares
were issued or outstanding during the past year. Future expenses may be greater
or less.

Example The table below shows what you would pay if you invested $1,000 over the
various time frames indicated. The example assumes you reinvested all dividends
and that the average annual return was 5%.

This example is for comparison purposes only and is not a representation of the
fund's actual expenses and returns, either past or future.

(1) Except for investments of $1 million or more; see "How sales charges are
    calculated."
(2) Does not include wire redemption fee (currently $4.00).
(3) Because of the 12b-1 fee, long-term shareholders may indirectly pay more
    than the equivalent of the maximum permitted front-end sales charge.

CHOOSING A SHARE CLASS

All John Hancock income funds offer two classes of shares, Class A and Class B.
In addition, Class C shares are available for High Yield Bond Fund and Strategic
Income Fund. Each class has its own cost structure as outlined below, allowing
you to choose the one that best meets your requirements. For more details, see
"How Sales Charges are Calculated." Your financial representative can help you
decide which share class is best for you.

- -------------------------------------------------------------------------------
 Class A - for all funds
- -------------------------------------------------------------------------------

    o Front-end sales charges. There are several ways to reduce these charges,
      described under "Sales Charge Reductions and Waivers" on the following
      page.

    o Lower annual expenses than Class B and Class C shares.

- -------------------------------------------------------------------------------
 Class B - for all funds
- -------------------------------------------------------------------------------

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

    o Higher annual expenses than Class A shares.

    o A contingent deferred sales charge that declines from 3% over four years
      for Intermediate Maturity Government Fund, and from 5% over 6 years for
      all other income funds.

    o Automatic conversion to Class A shares after five years for Intermediate
      Maturity Givernment Fund and after eight years for all other income funds,
      thus reducing future annual expenses.


- -------------------------------------------------------------------------------
 Class C - for selected funds
- -------------------------------------------------------------------------------

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

    o Higher annual expenses than Class A shares. o A 1% contingent deferred
      sales charge on shares sold within one year of purchase.

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

For actual past expenses of Class A and Class B shares, see the fund-by-fund
information earlier in this prospectus.

It is presently the policy of Signature Services not to accept any order of
$100,000 or more for Class B shares or any order of $1 million or more for Class
C shares. In these circumstances it would be more beneficial for the investor to
purchase Class A shares.

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 (Groups 1 and 2)
- --------------------------------------------------------------------------------
 Your investment                            CDSC on shares being sold
- -------------------------------------------------------------------------------
 First $1M - $4,999,999                     1.00%
 Next $1 - $5M above that                   0.50%
 Next $1 or more above that                 0.25%

For purposes of this CDSC, all purchases made during a calendar month are
counted as having been made on the 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 longer
the time between the purchase and the sale of shares, the lower the rate of the
CDSC:

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

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. 

   
Class C 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) of 1% on shares you sell within one year of purchase. 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.

SALES CHARGE REDUCTIONS AND WAIVERS

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

o   Accumulation Privilege -- lets you add the value of any Class A shares you
    already own to the amount of your next Class A investment for purposes of
    calculating the sales charge.

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 to add these options (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

To utilize: if you think you may be eligible for a CDSC waiver, contact your
financial representative or Signature Services, or consult the SAI.

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.


                                                                YOUR ACCOUNT  17

   non-discretionary accounts

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)

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

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 received 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. In addition, Signature Services 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, Signature Services is not
responsible for any losses that may occur to any account due to an unauthorized
telephone call. Also for your protection, telephone transactions are not
permitted on accounts whose names or addresses have changed within the past 30
days. Proceeds from telephone transactions can only be mailed to the address of
record.

   
Exchanges You may exchange shares of one John Hancock fund for shares of the
same class of any other, generally without paying any additional sales charges.
The registration for both accounts involved must be identical. Class B and Class
C shares will continue to age from the original date and will retain the same
CDSC rate 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.

- --------------------------------------------------------------------------------
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.
Short- and long-term capital gains, if any, are distributed annually, typically
after the end of a fund's fiscal year. 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.


22  YOUR ACCOUNT
<PAGE>

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.

Consequently, dividends you receive from a fund, whether reinvested or taken as
cash, are generally considered taxable. Dividends from a fund's long-term
capital gains are taxable as capital gains; dividends from other sources are
generally taxable as ordinary income. Some dividends paid in January may be
taxable as if they had been paid the previous December.

The Form 1099 that is mailed to you every January details your dividends and
their federal tax category, although you should verify your tax liability with
your tax professional.

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

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

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

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

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

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

o  Make sure you have at least $5,000 worth of shares in your account.

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

   
Retirement plans John Hancock Funds offers a range of retirement plans,
including IRAs, SIMPLE IRAs, SIMPLE 401(k)s, SEPs, 401(k)s, and money purchase
pension and profit-sharing plans. Using these plans, you can invest in any John
Hancock fund (except tax-free income funds) with a low minimum investment of
$250 or, for some group plans, no minimum investment at all. To find out more,
call Signature Services at 1-800-225-5291.

Fund details

- --------------------------------------------------------------------------------
BUSINESS STRUCTURE

How the funds are organized Each John Hancock income fund is an open-end
management investment company or a series of such a company.

Each fund is supervised by a board of trustees, an independent body that has
ultimate responsibility for the fund's activities. The board retains various
companies to carry out the fund's operations, including the investment adviser,
custodian, transfer agent and others (see diagram). The board has the right, and
the obligation, to terminate the fund's relationship with any of these companies
and to retain a different company if the board believes it is in the
shareholders' best interests. 

At a mutual fund's inception, the initial shareholder (typically the adviser)
appoints the fund's board. Thereafter, the board and the shareholders determine
the board's membership. The boards of the John Hancock income funds may include
individuals who are affiliated with the investment adviser. However, the
majority of board members must be independent.

The funds do not hold annual shareholder meetings, but may hold special meetings
for such purposes as electing or removing board members, changing fundamental
policies, approving a management contract or approving a 12b-1 plan (12b-1 fees
are explained in "Sales compensation").

Accounting compensation The funds compensate the adviser for performing tax and
financial management services. Annual compensation is not expected to exceed
0.02% of each fund's average net assets.

Portfolio trades In placing portfolio trades, the adviser may use brokerage
firms that market the fund's shares or are affiliated with John Hancock Mutual
Life Insurance Company, but only when the adviser believes no other firm offers
a better combination of quality execution (i.e., timeliness and completeness)
and favorable price.

Investment goals Except for Government Income Fund, High Yield Bond Fund and
Intermediate Maturity Government Fund, each fund's investment goal is
fundamental and may only be changed with shareholder approval.

Diversification All of the income funds are diversified.

SALES COMPENSATION

As part of their business strategies, the 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 ("12b-1" refers to the federal
securities regulation that authorizes annual fees of this type). The 12b-1 fee
rates vary by fund and by share class, according to Rule 12b-1 plans adopted by
the funds. The sales charges and 12b-1 fees paid by investors are detailed in
the fund-by-fund information. The portions of these expenses that are reallowed
to financial services firms are shown on the next page.

   
Distribution fees may be used to pay for sales compensation to financial
services firms, marketing and overhead expenses and, for Class B and Class C
shares, interest expenses.

Sovereign Bond                           $ 3,985,198          3.07%
Sovereign U.S. Gov. Income               $ 5,472,842          5.27%

(1) As of the most recent fiscal year end covered by each fund's financial
    highlights. These expenses may be carried forward indefinitely.

   
Class C shares had not begun operations during the 1997 fiscal year; therefore,
there are no unreimbursed expenses to report.
    

Initial compensation Whenever you make an investment in a fund or funds, 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.

Annual compensation 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.

MORE ABOUT RISK

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

The funds are 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 a fund utilizes these
securities or practices, its overall performance may be affected, either
positively or negatively. On the following pages are brief descriptions of these
securities and investment practices, along with the risks associated with them.
The funds follow certain policies that may reduce these risks.

As with any mutual fund, there is no guarantee that a John Hancock income fund
will earn income or show a positive total 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.

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.

Currency risk The risk that fluctuations in the exchange rates between the U.S.
dollar and foreign currencies may negatively affect an investment. Adverse
changes in exchange rates may erode or reverse any gains produced by foreign
currency-denominated investments, and may widen any losses.

Extension risk The risk that an unexpected rise in interest rates will extend
the life of a mortgage-backed security beyond the expected prepayment time,
typically reducing the security's value.

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.

Leverage risk Associated with securities or practices (such as borrowing) that
multiply small index or market movements into large changes in value.

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.

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.

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. Market risk may affect a single issuer, an
industry, a sector of the bond market or the market as a whole. Common to all
stocks and bonds and the mutual funds that invest in them.

Natural event risk The risk of losses attributable to natural disasters, crop
failures and similar events.

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.

Political risk The risk of losses attributable to government or political
actions, from changes in tax or trade statutes to governmental collapse and war.

   
Prepayment risk The risk that unanticipated prepayments may occur during periods
of falling interest rates, reducing the value of mortgage-backed securities.
    

Valuation risk The risk that a fund has valued certain of its securities at a
higher price than it can sell them for.

ORGANIZATION OF THE FUND

   
The Fund is series of the Trust, an open-end investment management company
organized as a Massachusetts business trust under the laws of The Commonwealth
of Massachusetts. The Fund was organized in April 1986.
    

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 and policies discussed in the Prospectus. There is no assurance that
the Fund will achieve its investment objective.

The investment objective of the Fund is a high level of current income. The Fund
will seek to achieve its investment objective by investing primarily in: (i)
foreign government and corporate debt securities, (ii) U.S. Government
securities and (iii) lower-rated high yield high risk debt securities of U.S.
issuers.
    

Lower Rated Securities. The higher yields and high income sought by the Fund are
generally obtainable from high yield risk securities in the lower rating
categories of the established rating services. These securities are rated below
Baa by Moody's Investors Service, Inc. ("Moody's") or below BBB by Standard &
Poor's Ratings Group ("Standard & Poor's"). The Fund may invest in securities
rated as low as Ca by Moody's or CC by Standard & Poor's, which may indicate
that the obligations are speculative to a high degree and in default. Lower
rated securities are generally referred to as junk bonds. See the Appendix
attached to this Statement of Additional Information for a description of the
characteristics of the various ratings categories. The Fund is not obligated to
dispose of securities whose issuers subsequently are in default or which are
downgraded below the minimum ratings noted above. The credit ratings of Moody's
and Standard & Poor's (the "Rating Agencies"), such as those ratings described
in this Statement of Additional Information, may not be changed by the Rating
Agencies in a timely fashion to reflect subsequent economic events. The credit
ratings of securities do not evaluate market risk. The Fund may also invest in
unrated securities which, in the opinion of the Adviser, offer comparable yields
and risks to the rated securities in which the Fund may invest.

Ratings as Investment Criteria. In general, the ratings of Moody's and S&P
represent the opinions of these agencies as to the quality of the securities
which they rate. It should be emphasized however, that ratings are relative and
subjective and are not absolute standards of quality. These ratings will be used
by the Funds as initial criteria for the selection of portfolio securities.
Among the factors which will be considered are the long-term ability of the
issuer to pay principal and interest and general economic trends. Appendix A
contains further information concerning the rating of Moody's and S&P and their
significance.

Subsequent to its purchase by the Fund, an issue of securities may cease to be
rated or its rating may be reduced below the minimum required for purchase by
the Fund. Neither of these events will require the sale of the securities by the
Fund.


                                       2
<PAGE>

Debt securities that are rated in the lower rating categories, or which are
unrated, involve greater volatility of price and risk of loss of principal and
income. In addition, lower ratings reflect a greater possibility of an adverse
change in financial condition affecting the ability of the issuer to make
payments of interest and principal. The market price and liquidity of lower
rated 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. Although the Adviser seeks to minimize these risks
through diversification, investment analysis and attention to current
developments in interest rates and economic conditions, there can be no
assurance that the Adviser will be successful in limiting the Fund's exposure to
the risks associated with lower rated securities. Because the Fund invests in
securities in the lower rated categories, the achievement of the Fund's goals is
more dependent on the Adviser's ability than would be the case if the Fund were
investing in securities in the higher rated categories.

The Fund's investments in debt securities may include increasing rate note
securities, zero coupon bonds and payment-in-kind bonds. Zero coupon bonds have
a determined interest rate, but payment of the interest is deferred until
maturity of the bonds. Payment- in-kind securities pay interest in either cash
or additional securities, at the issuer's option, for a specified period. The
market prices of zero coupon and payment-in-kind bonds are affected to a greater
extent by interest rate changes, and thereby tend to be more volatile than
securities which pay interest periodically and in cash. Increasing rate note
securities are typically refinanced by the issuers within a short period of
time.

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

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 Fund's investments in high yield high risk securities and to value
accurately these 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 Fund's investments, and
consequently its net asset value, will be subject to the market fluctuations and
risk inherent in all securities.

Foreign Securities. The Fund may invest in debt obligations (which may be
denominated in the U.S. dollar or in non-U.S. currencies) issued or guaranteed
by foreign corporations, certain supranational entities (such as the World
Bank), and foreign governments (including political subdivisions having taxing
authority) or their agencies or instrumentalities. The Fund may also invest in
debt securities that are issued by U.S. corporations and denominated in non-U.S.
currencies. No more than 25% of the Fund's total assets, at the time of
purchase, will be invested in government securities of any one foreign country.

The Fund may also invest in American Depository Receipts ("ADRs"). ADRs
(sponsored and unsponsored) are receipts typically issued by an American bank or
trust company which evidence 


                                       3
<PAGE>

ownership of underlying securities issued by a foreign corporation, and are
designed for trading in United States securities markets. Issuers of unsponsored
ADRs are not contractually obligated to disclose material information in the
United States, and, therefore, there may not be a correlation between that
information and the market value of an unsponsored ADR.

The percentage of the Fund's assets that will be allocated to foreign securities
will vary depending on the relative yields of foreign and U.S. securities, the
economies of foreign countries, the condition of such countries' financial
markets, the interest rate climate of such countries and the relationship of
such countries' currency to the U.S. dollar. These factors are judged on the
basis of fundamental economic criteria (e.g., relative inflation levels and
trends, growth rate forecasts, balance of payments status and economic policies)
as well as technical and political data. Although the Fund may invest in any
country where the Adviser believes there is a potential to achieve the Fund's
investment objective, it presently expects to invest primarily in securities of
issuers in industrialized Western European countries (including Scandinavian
countries) and in Canada, Japan, Australia and New Zealand. Investments in
securities of issuers in non-industrialized countries generally involve more
risk and may be considered highly speculative.

The value of portfolio securities denominated in foreign currencies may increase
or decrease in response to changes in currency exchange rates. The Fund will
incur costs in connection with converting between currencies.

Foreign Currency Transactions. The Fund may enter into forward foreign currency
contracts involving currencies of the different countries in which it will
invest as a hedge against possible variations in the foreign exchange rate
between these currencies as well as to enhance return or as a substitute for the
purchase or sale of currency. The foreign currency transactions of the Fund may
be conducted on a spot (i.e., cash) basis at the spot rate for purchasing or
selling currency prevailing in the foreign exchange market. Forward foreign
currency contracts are contractual agreements to purchase or sell a specified
currency at a specified future date and price set at the time of the contract.
Transaction hedging is the purchase or sale of forward foreign currency
contracts with respect to specific receivables for payables of the Fund accruing
in connection with the purchase and sale of its portfolio securities denominated
in foreign currencies. Portfolio hedging is the use of forward foreign currency
contracts to offset portfolio security positions denominated or quoted in such
foreign currencies. The Fund will not attempt to hedge all of its foreign
portfolio positions and will enter into such transactions only to the extent, if
any, deemed appropriate by the Adviser.

If the Fund enters into a forward contract requiring it to purchase foreign
currency, its custodian bank will segregate cash or liquid securities in a
separate account of the Fund in an amount equal to the value of the Fund's total
assets committed to the consummation of such forward contract. Those assets will
be valued at market daily and if the value of the assets in the separate account
declines, additional cash or securities will be placed in the account so that
the value of the account will equal the amount of the Fund's commitment with
respect to such contracts.

Hedging against a decline in the value of a currency does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of such securities decline. Such transactions also preclude the
opportunity for gain if the value of the hedged currency should rise. Moreover,
it may not be possible for the Fund to hedge against a devaluation that is so
generally anticipated that the Fund is not able to contract to sell the currency
at a price above the devaluation level it anticipates.

There is no limitation on the value of the Fund's assets that may be committed
to forward contracts or on the term of a forward contract. In addition to the
risks described above, forward contracts are subject to the following additional
risks: (1) that a Fund's performance will be adversely affected by 


                                       4
<PAGE>

unexpected changes in currency exchange rates; (2) that the counterparty to a
forward contract will fail to perform its contractual obligations; (3) that a
Fund will be unable to terminate or dispose of its position in a forward
contract; and (4) with respect to hedging transactions in forward contracts,
that there will be imperfect correlation between price changes in the forward
contract and price changes in the hedged portfolio assets.

The cost to the Fund of engaging in foreign currency transactions varies with
such factors as that currency involved, the length of the contract period and
the market conditions then prevailing. Since transactions in foreign currency
are usually conducted on a principal basis, no fees or commissions are involved.

Global Risks. Investments in foreign securities may involve certain risks not
present in domestic investments due to exchange controls, less publicly
available information, more volatile or less liquid securities markets, and the
possibility of expropriation, confiscatory taxation or political, economic or
social instability. There may be difficulty in enforcing legal rights outside
the United States. Some foreign companies are not subject to the same uniform
financial reporting requirements, accounting standards and governmental
supervision as domestic companies, and foreign exchange markets are regulated
differently from the U.S. stock market. Security trading practices abroad may
offer less protection to investors such as the Fund. In addition, foreign
securities may be denominated in the currency of the country in which the issuer
is located. Consequently, changes in the foreign exchange rate will affect the
value of the Fund's shares and dividends. Finally, you should be aware that the
expense ratios of international funds generally are higher than those of
domestic funds, because there are greater costs associated with maintaining
custody of foreign securities and the increased research necessary for
international investing results in a higher advisory fee.

These risks may be intensified in the case of investments in emerging markets or
countries with limited or developing capital markets. These countries are
located in the Asia-Pacific region, Eastern Europe, Latin and South America and
Africa. Security prices in these markets can be significantly more volatile than
in more developed countries, reflecting the greater uncertainties of investing
in less established markets and economies. Political, legal and economic
structures in many of these emerging market countries may be undergoing
significant evolution and rapid development, and they may lack the social,
political, legal and economic stability characteristic of more developed
countries. Emerging market countries may have failed in the past to recognize
private property rights. They may have relatively unstable governments, present
the risk of nationalization of businesses, restrictions on foreign ownership, or
prohibitions on repatriation of assets, and may have less protection of property
rights than more developed countries. Their economies may be predominately based
on only a few industries, may be highly vulnerable to changes in local or global
trade conditions, and may suffer from extreme and volatile debt burdens or
inflation rates. Local securities markets may trade a small number of securities
and may be unable to respond effectively to increases in trading volume,
potentially making prompt liquidation of substantial holdings difficult or
impossible at times. The Fund may be required to establish special custodial or
other arrangements before making certain investments in these countries.
Securities of issuers located in these countries may have limited marketability
and may be subject to more abrupt or erratic price movements.

The Fund may acquire other restricted securities including securities for which
market quotations are not readily available. These securities may be sold only
in privately negotiated transactions or in public offerings with respect to
which a registration statement is in effect under the 1933 Act. Where
registration is required, the Fund may be obligated to pay all or part of the
registration expenses and a considerable period may elapse between the time of
the decision to sell and the time


                                       5
<PAGE>

the Fund may be permitted to sell a security under an effective registration
statement. If, during such a period, adverse market conditions were to develop,
the Fund might obtain a less favorable price than prevailed when it decided to
sell. Restricted securities will be priced at fair market value as determined in
good faith by the Fund's Trustees.

Repurchase Agreements. In a repurchase agreement the Fund would buy 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 and the expense of enforcing its rights.

Reverse Repurchase Agreements. The Fund may also enter into reverse repurchase
agreements which involve the sale of U.S. Government securities held in its
portfolio to a bank with an agreement that the Fund will buy back the securities
at a fixed future date at a fixed price plus an agreed amount of "interest"
which may be reflected in the repurchase price. Reverse repurchase agreements
are considered to be borrowings by the Fund. Reverse repurchase agreements
involve the risk that the market value of securities purchased by the Fund with
proceeds of the transaction may decline below the repurchase price of the
securities sold by the Fund which it is obligated to repurchase. The Fund will
also continue to be subject to the risk of a decline in the market value of the
securities sold under the agreements because it will reacquire those securities
upon effecting their repurchase. The Fund will not enter into reverse repurchase
agreements and other borrowings exceeding in the aggregate 33% of the market
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 Board of Trustees.
Under procedures established by the Board of Trustees, the Adviser will monitor
the creditworthiness of the banks involved.

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.
However, the Fund will not invest more than 15% 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) paper or Rule 144A securities, that
they are liquid, they will not be subject to the 15% limit in illiquid
investments. The Trustees may adopt guidelines and delegate to the Adviser the
daily function of determining and monitoring the 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 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

Options on Securities, Securities Indices and Currency. The Fund may purchase
and write (sell) call and put options on any securities in which it may invest,
on any securities index based on securities in which it may invest or on any
currency in which Fund investments may be denominated. 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 to enhance total return, as a
substitute for the purchase or sale of securities or currency, 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 or currency written by the
Fund obligates the Fund to sell specified securities or currency 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 or currency written by the Fund
obligates the Fund to purchase specified securities or currency 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 or foreign currency assets 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 or foreign currency assets 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,
either of which may be quoted or denominated in any currency, in a segregated
account maintained by the Fund's custodian 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 or currencies 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 or currency at a specified price during
the option period. The Fund would ordinarily realize a gain on the purchase of a
call option if, during the option period, the value of such securities or
currency exceeded the sum of the exercise price, the premium paid and
transaction costs; otherwise the Fund would realize either no gain or a loss on
the purchase of the call option.

The purchase of a put option would entitle the Fund, in exchange for the premium
paid, to sell specified securities or currency at a specified price during the
option period. The purchase of 


                                       7
<PAGE>

protective puts is designed to offset or hedge against a decline in the market
value of the Fund's portfolio securities or the currencies in which they are
denominated. Put options may also be purchased by the Fund for the purpose of
affirmatively benefiting from a decline in the price of securities or currencies
which it does not own. 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.

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 a domestic or foreign 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
currencies 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 or currencies.

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

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

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


                                       8
<PAGE>

fluctuations and, for hedging transactions, the degree of correlation between
the options and securities or currency markets.

Futures Contracts and Options on Futures Contracts. To seek to increase total
return or hedge against changes in interest rates, securities prices or currency
exchange rates, the Fund may purchase and sell various kinds of futures
contracts, and purchase and write call and put options on these futures
contracts. The Fund may also enter into closing purchase and sale transactions
with respect to any of these contracts and options. The futures contracts may be
based on various securities (such as U.S. Government securities), securities
indices, foreign currencies and any other financial instruments and indices. All
futures contracts entered into by the Fund are traded on U.S. or foreign
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 or
currencies 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 or currency will usually be
liquidated in this manner, the Fund may instead make, or take, delivery of the
underlying securities or currency 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. 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 or the
exchange rate of currencies in which portfolio securities are quoted or
denominated. 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
seek to offset anticipated changes in the value of a currency in which its
portfolio securities, or securities that it intends to purchase, are quoted or
denominated by purchasing and selling futures contracts on such currencies.

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 or foreign currency rates that
would adversely affect the dollar 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. Similarly, the Fund may sell futures contracts on
any currencies in which its portfolio securities are quoted or denominated or in
one currency to hedge against fluctuations in the value of securities
denominated in a different currency if there is an established historical
pattern of correlation between the two currencies.

If, in the opinion of the Adviser, there is a sufficient degree of correlation
between price trends for the Fund's portfolio securities and futures contracts
based on other financial instruments, securities indices or other indices, the
Fund may also enter into such futures contracts as part of its hedging strategy.
Although under some circumstances prices of securities in the Fund's portfolio
may be more or less volatile than prices of such futures contracts, the Adviser
will attempt to estimate the 


                                       9
<PAGE>

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 or currency exchange rates 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 or foreign currency, to alter the investment characteristics of or
currency exposure associated with portfolio securities or to gain or increase
its exposure to a particular securities market or currency.

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 either for bona fide hedging purposes or to seek to increase total
return as permitted by the CFTC. To the extent that the Fund is using futures
and related options for hedging purposes, futures contracts will be sold to
protect against a decline in the price of securities (or the currency in which
they are quoted or denominated) that the Fund owns or futures contracts will be
purchased to protect the Fund against an increase in the price of securities (or
the currency in which they are quoted or denominated) 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 


                                       10
<PAGE>

have purchased, or will be in the process of purchasing, equivalent amounts of
related securities (or assets denominated in the related currency) in the cash
market at the time when the futures or option position is closed out. However,
in particular cases, when it is economically advantageous for the Fund to do so,
a long futures position may be terminated or an option may expire without the
corresponding purchase of securities or other assets.

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

Transactions in futures contracts and options on futures involve brokerage
costs, require margin deposits and, in the case of contracts and options
obligating the Fund to purchase securities or currencies, require the Fund to
establish with the custodian 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, securities prices or currency
exchange rates 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. There are no futures contracts based upon
individual securities, except certain U.S. Government securities. The only
futures contracts available to hedge the Fund's portfolio are various futures on
U.S. Government securities, securities indices and foreign currencies. 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. In addition, it is not
possible to hedge fully or protect against currency fluctuations affecting the
value of securities denominated in foreign currencies because the value of such
securities is likely to fluctuate as a result of independent factors not related
to currency fluctuations.

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.

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


                                       11
<PAGE>

result in the Fund's losing the opportunity to obtain a price and yield
considered to be advantageous. The purchase of securities on a when-issued or
forward commitment basis also involves a risk of loss if the value of the
security to be purchased declines prior to the settlement date.

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

Borrowing. The Fund may borrow money in an amount that does not exceed 33% of
its total assets. Borrowing by the Fund involves leverage, which may exaggerate
any increase or decrease in the Fund's investment performance and in that
respect may be considered a speculative practice. The interest that the Fund
must pay on any borrowed money, additional fees to maintain a line of credit or
any minimum average balances required to be maintained are additional costs
which will reduce or eliminate any potential investment income and may offset
any capital gains. Unless the appreciation and income, if any, on the asset
acquired with borrowed funds exceed the cost of borrowing, the use of leverage
will diminish the investment performance of the Fund.

Short Sales. The Fund may engage in short sales in order to profit from an
anticipated decline in the value of a security. The Fund may also engage in
short sales to attempt to limit its exposure to a possible market decline in the
value of its portfolio securities through short sales of securities which the
Adviser believes possess volatility characteristics similar to those being
hedged. To effect such a transaction, the Fund must borrow the security sold
short to make delivery to the buyer. The Fund then is obligated to replace the
security borrowed by purchasing it at the market price at the time of
replacement. Until the security is replaced, the Fund is required to pay to the
lender any accrued interest or dividends and may be required to pay a premium.
The Fund may only make short sales "against the box," meaning that the Fund, by
virtue of its ownership of other securities, has the right to obtain securities
equivalent in kind and amount to the securities sold and, if the right is
conditional, the sale is made upon the same conditions.

The Fund will realize a gain if the security declines in price between the date
of the short sale and the date on which the Fund replaces the borrowed security.
On the other hand, the Fund will incur a loss as a result of the short sale if
the price of the security increases between those dates. The amount of any gain
will be decreased, and the amount of any loss increased, by the amount of any
premium or interest or dividends the Fund may be required to pay in connection
with a short sale. The successful use of short selling as a hedging device may
be adversely affected by imperfect correlation between movements in the price of
the security sold short and the securities being hedged.

Under applicable guidelines of the staff of the SEC, if the Fund engages in
short sales, it must put in a segregated account (not with the broker) an amount
of cash or U.S. Government securities equal to the difference between (a) the
market value of the securities sold short at the time they were sold short and
(b) any cash or U.S. Government securities required to be deposited as
collateral with the broker in connection with the short sale (not including the
proceeds from the short sale). In addition, until the Fund replaces the borrowed
security, it must daily maintain the segregated account at such a level that the
amount deposited in it plus the amount deposited with the broker as collateral
will equal the current market value of the securities sold short.

Short selling may produce higher than normal portfolio turnover which may result
in increased transaction costs to the Fund and may result in gains from the sale
of securities deemed to have been 


                                       12
<PAGE>

held for less than three months, which gains must be less than 30% of the Fund's
gross income for a taxable year in order for the Fund to qualify as a regulated
investment company under the Internal Revenue Code of 1986, as amended (the
"Code") for that year.

U.S. Governmental Securities. Certain U.S. Government securities, including U.S.
Treasury bills, notes and bonds, and Government National Mortgage Association
mortgage-backed 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 instrumentalities such as the Federal Home
Loan Mortgage Corporation ("Freddie Macs"), the Federal National Mortgage
Association ("Fannie Maes") and the Student Loan Marketing Association ("Sallie
Maes"). No assurance can be given that the U.S. Government will provide
financial support to these Federal agencies, authorities, instrumentalities and
government sponsored enterprises in the future.

Mortgage-Backed Securities. Ginnie Maes, Freddie Macs and Fannie Maes are
mortgage-backed securities which provide monthly payments that are, in effect, a
"pass- through" of the monthly interest and principal payments (including any
pre-payments) made by the individual borrowers on the pooled mortgage loans.
Collateralized Mortgage Obligations ("CMOs"), in which the Fund may also invest,
are securities issued by a U.S. Government instrumentality that are
collateralized by a portfolio of mortgages or mortgage-backed securities. During
periods of declining interest rates, principal and interest on mortgage-backed
securities may be prepaid at faster-than-expected rates. The proceeds of these
prepayments typically can only be invested in lower-yielding securities.
Therefore, mortgage-backed securities may be less effective at maintaining
yields during periods of declining interest rates than traditional debt
securities of similar maturity. U.S. Government agencies and instrumentalities
include, but are not limited to, Federal Farm Credit Banks, Federal Home Loan
Banks, the Federal Home Loan Mortgage Corporation, the Student Loan Marketing
Association, and the Federal National Mortgage Association. Some obligations
issued by an agency or instrumentality may be supported by the full faith and
credit of the U.S. Treasury.

A real estate mortgage investment conduit, or REMIC, is a private entity formed
for the purpose of holding a fixed pool of mortgages secured by an interest in
real property, and of issuing multiple classes of interests therein to investors
such as the Fund. The Fund may consider REMIC securities as possible investments
when the mortgage collateral is insured, guaranteed or otherwise backed by the
U.S. Government or one or more of its agencies or instrumentalities. The Fund
will not invest in "residual" interests in REMIC's because of certain tax
disadvantages for regulated investment companies that own such interests.

Risks of Mortgage-Backed Securities. Different types of mortgage-backed
securities are subject to different combinations of prepayment, extension,
interest rate and/or other market risks. Conventional mortgage pass-through
securities and sequential pay CMOs are subject to all of these risks, but are
typically not leveraged. PACs, TACs and other senior classes of sequential and
parallel pay CMOs involve less exposure to prepayment, extension and interest
rate risk than other mortgage-backed securities, provided that prepayment rates
remain within expected prepayment ranges or "collars."

The value of mortgage-backed securities may also change due to shifts in the
market's perception of issuers. In addition, regulatory or tax changes may
adversely affect the mortgage-backed securities market as a whole.
Non-government mortgage-backed securities may offer higher yields than those


                                       13
<PAGE>

issued by government entities, but also may be subject to greater price changes
than government issues.

Mortgage "Dollar Roll" Transactions. The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers pursuant to which the
Fund sells mortgage-backed securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date. The Fund will only enter into covered rolls. A "covered roll" is a
specific type of dollar roll for which there is an offsetting cash position or a
cash equivalent security position which matures on or before the forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior security and will be excluded from the calculation
of the Fund's borrowing and other senior securities. For financial reporting and
tax purposes, the Fund treats mortgage dollar rolls as two separate
transactions; one involving the purchase of a security and a separate
transaction involving a sale. The Fund does not currently intend to enter into
mortgage dollar roll transactions that are accounted for as a financing.

Asset-Backed Securities. The Fund may invest a portion of its assets in
asset-backed securities. Asset-backed securities are often subject to more rapid
repayment than their stated maturity date would indicate as a result of the
pass-through of prepayments of principal on the underlying loans. During periods
of declining interest rates, prepayment of loans underlying asset-backed
securities can be expected to accelerate. Accordingly, the Fund's ability to
maintain positions in these securities will be affected by reductions in the
principal amount of such securities resulting from prepayments, and its ability
to reinvest the returns of principal at comparable yields is subject to
generally prevailing interest rates at that time.

Credit card receivables are generally unsecured and the debtors on such
receivables are entitled to the protection of a number of state and federal
consumer credit laws, many of which give such debtors the right to set-off
certain amounts owed on the credit cards, thereby reducing the balance due.
Automobile receivables generally are secured, but by automobiles rather than
residential real property. Most issuers of automobile receivables permit the
loan services to retain possession of the underlying obligations. If the service
were to sell these obligations to another party, there is a risk that the
purchaser would acquire an interest superior to that of the holders of the
asset-backed securities. In addition, because of the large number of vehicles
involved in a typical issuance and technical requirements under state laws, the
trustee for the holders of the automobile receivables may not have a proper
security interest in the underlying automobiles. Therefore, there is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

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 benchmark 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.

Participation Interests. Participation interests, which may take the form of
interests in, or assignments of certain loans, are acquired from banks who have
made these loans or are members of 


                                       14
<PAGE>

a lending syndicate. The Fund's investments in participation interests may be
subject to its 15% limitation on investments in illiquid securities.

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,
currency 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. For example, if the Fund agreed to exchange payments
in dollars for payments in a foreign currency, the swap agreement would tend to
decrease the Fund's exposure to U.S. interest rates and increase its exposure to
foreign currency and interest rates. 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.

Pay-In-Kind, Delayed and Zero Coupon Bonds. The Fund may invest in pay-in-kind,
delayed and zero coupon bonds. These are securities issued at a discount from
their face value because interest payments are typically postponed until
maturity. The amount of the discount rate varies depending on factors including
the time remaining until maturity, prevailing interest rates, the security's
liquidity and the issuer's credit quality. These securities also may take the
form of debt securities that have been stripped of their interest payments. A
portion of the discount with respect to stripped tax-exempt securities or their
coupons may be taxable. The market prices in pay-in-kind, delayed and zero
coupon bonds generally are more volatile than the market prices of
interest-bearing securities and are likely to respond to a grater degree to
changes in interest rates than interest-bearing securities having similar
maturities and credit quality. The Fund's investments in pay-in-kind, delayed
and zero coupon bonds may require the Fund to sell certain of its portfolio
securities to generate sufficient cash to satisfy certain income distribution
requirements. See "Tax Status."

Brady Bonds. The Fund may invest in so-called "Brady Bonds" and other sovereign
debt securities of countries that have restructured or are in the process of
restructuring sovereign debt pursuant to 


                                       15
<PAGE>

the Brady Plan. Brady Bonds are debt securities described as part of a
restructuring plan created by U.S. Treasury Secretary Nicholas F. Brady in 1989
as a mechanism for debtor nations to restructure their outstanding external
indebtedness (generally, commercial bank debt). In restructuring its external
debt under the Brady Plan framework, a debtor nation negotiates with its
existing bank lenders as well as multilateral institutions such as the World
Bank and the International Monetary Fund (the "IMF"). The Brady Plan facilitate
the exchange of commercial bank debt for newly issued (known as Brady Bonds).
The World Bank and IMF provide funds pursuant to loan agreements or other
arrangements which enable the debtor nation to collateralize the new Brady Bonds
or to repurchase outstanding bank debt at a discount. Under these arrangements
IMF debtor nations are required to implement of certain domestic monetary and
fiscal reforms. These reforms have included the liberalization of trade and
foreign investment, the privatization of state-owned enterprises and the setting
of targets for public spending and borrowing. These policies and programs
promote the debtor country's ability to service its external obligations and
promote its economic growth and development. The Brady Plan only sets forth
general guiding principles for economic reform and debt reduction, emphasizing
that solutions must be negotiated on a case-by-case basis between debtor nations
and their creditors. The Adviser believes that economic reforms undertaken by
countries in connection with the issuance of Brady Bonds make the debt of
countries which have issued or have announced plans to issue Brady Bonds an
attractive opportunity for investment.

Brady Bonds have recently been issued by Argentina, Brazil, Bulgaria, Costa
Rica, Dominican Republic, Ecuador, Jordan, Mexico, Nigeria, Poland, the
Philippines, Uruguay and Venezuela and may be issued by other countries. Over
$130 billion in principal amount of Brady Bonds have been issued to date, the
largest portion having been issued by Argentina and Brazil. Brady Bonds may
involve a high degree of risk, may be in default or present the risk of default.
As of January, 1, 1997, the Fund is not aware of the occurrence of any payment
defaults on Brady Bonds. Investors should recognize however, that Brady Bonds
have been issued only recently, and, accordingly, they do not have a long
payment history. Agreements implemented under the Brady Plan to date are
designed to achieve debt and debt-service reduction through specific options
negotiated by a debtor nation with its creditors. As a result, the financial
packages offered by each country differ. The types of options have included the
exchange of outstanding commercial bank debt for bonds issued at 100% of face
value of such debt, bonds issued at a discount of face value of such debt, bonds
bearing an interest rate which increases over time and bonds issued in exchange
for the advancement of new money by existing lenders. Certain Brady Bonds have
been collateralized as to principal due at maturity by U.S. Treasury zero coupon
bonds with a maturity equal to the final maturity of such Brady Bonds, although
the collateral is not available to investors until the final maturity of the
Brady Bonds. Collateral purchases are financed by the IMF, the World Bank and
the debtor nations' reserves. In addition, the first two or three interest
payments on certain types of Brady Bonds may be collateralized by cash or
securities agreed upon by creditors. Although Brady Bonds may be collateralized
by U.S. Government securities, repayment of principal and interest is not
guaranteed by the U.S. Government.

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


                                       16
<PAGE>

Rights and Warrants. The Fund may purchase warrants and rights which are
securities permitting, but not obligating, their holder to purchase the
underlying securities at a predetermined price subject to the Fund's Investment
Restrictions. Generally, warrants and stock purchase rights do not carry with
them the right to receive dividends or exercise voting rights with respect to
the underlying securities, and they do not represent any rights in the assets of
the issuer. As a result, an investment in warrants and rights may be considered
to entail greater investment risk than certain other types of investments. In
addition, the value of warrants and rights does not necessarily change with the
value of the underlying securities, and they cease to have value if they are not
exercised on or prior to their expiration date. Investment in warrants and
rights increases the potential profit or loss to be realized from the investment
of a given amount of the Fund's assets as compared with investing the same
amount in the underlying stock.

Time Deposits. The Securities and Exchange Commission ("SEC") considers time
deposits with periods of greater than seven days to be illiquid, subject to the
restriction that illiquid securities are limited to no more than 15% of the
Fund's net 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 stock
market conditions, changes in interest rates or other economic trends and
developments or to take advantage of yield disparities between 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 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 the approval of a majority of the Fund's outstanding
voting securities which, as used in the Prospectus and this Statement of
Additional Information, means the approval of the lesser of (1) the holders of
67% or more of the shares represented at a meeting if by 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 observes the fundamental restrictions listed in item (1) through (9)
below. The Fund may not:

(1)   Issue senior securities, except as permitted by paragraphs (2), (6) and
      (7) below. For purposes of this restriction, the issuance of shares of
      beneficial interest in multiple classes or series, the purchase or sale of
      options, futures contracts and options on futures contracts, forward
      foreign currency exchange contracts, forward commitments and repurchase
      agreements entered into in accordance with the Fund's investment policies,
      and the pledge, mortgage or hypothecation of the Fund's assets within the
      meaning paragraph (3) below, are not deemed to be senior securities.

(2)   Borrow money in amounts exceeding 33% of the Fund's total assets
      (including the amount borrowed) taken at market value. Interest paid on
      borrowing will reduce income available to shareholders.


                                       17
<PAGE>

(3)   Pledge, mortgage or hypothecate its assets, except to secure indebtedness
      permitted by paragraph (2) above and then only if such pledging,
      mortgaging or hypothecating does not exceed 33 1/3% of the fund's total
      assets taken at market value.

(4)   Act as an underwriter, except to the extent that in connection with the
      disposition of portfolio securities, the Fund may be deemed to be an
      underwriter for purposes of the Securities Act of 1933.

(5)   Purchase or sell real estate or any interest therein, except that the Fund
      may invest in securities of corporate or governmental entities secured by
      real estate or marketable interests therein or securities issued by
      companies that invest in real estate or interests therein.

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

(7)   Buy or sell commodity contracts, except futures contracts on securities,
      securities indices and currency and options on such futures, forward
      foreign currency exchange contracts, forward commitments, and repurchase
      agreements entered into in accordance with the Fund's investment policies.

(8)   Purchase the securities of issuers conducting their principal business
      activity in the same industry if, immediately after such purchase, the
      value of its investments in such industry would exceed 25% of its total
      assets taken at market value at the time of each investment. This
      limitation does not apply to investments in obligations of the U.S.
      Government or any of its agencies or instrumentalities.

(9)   Purchase securities of an issuer (other than the U.S. Government, its
      agencies or instrumentalities), if

(i)   more than 5% of the Fund's total assets taken at market value would be
      invested in the securities of such issuer, except that up to 25% of the
      Fund's total assets may be invested in securities issued or guaranteed by
      any foreign government or its agencies or instrumentalities, or,

(ii)  such purchase would at the time result in more than 10% of the outstanding
      voting securities of such issuer being held by the Fund.

In connection with the lending of portfolio securities under item (6) above,
such loans must at all times be fully collateralized and the Fund's custodian
must take possession of the collateral either physically or in book entry form.
Securities used as collateral must be marked to market daily.

Nonfundamental Investment Restrictions. The following investment restrictions
are designated as nonfundamental and may be changed by the Trustees
without shareholder approval.

The Fund may not:


                                       18
<PAGE>

(a)   Participate on a joint or joint-and-several basis in any securities
      trading account. The "bunching" of orders for the sale or purchase of
      marketable portfolio securities with other accounts under the management
      of the Adviser to save commissions or to average prices among them is not
      deemed to result in a joint securities trading account.

(b)   Purchase securities on margin (except that it may obtain such short-term
      credits as may be necessary for the clearance of transactions in
      securities and forward foreign currency exchange contracts and may make
      margin payments in connection with transactions in futures contracts and
      options on futures) or make short sales of securities unless by virtue of
      ownership of other securities, the Fund has the right to obtain securities
      equivalent in kind and amount to the securities sold and, if the right is
      conditional, the sale is made upon the same conditions.

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

(d)   Invest for the purpose of exercising control over or management of any
      company.

(e)   Invest more than 15% of its net assets in illiquid securities.

In addition, the Fund complies with the following nonfundamental limitation on
its investments:

Exercise any conversion, exchange or purchase rights associated with corporate
debt securities in the portfolio if, at the time, the value of all equity
interests would exceed 10% of the Fund's total assets taken at market value.

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 values or the total costs 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 its Trustees 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 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 $26 billion in 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 $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 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 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 membership; 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 the Fund as follows:
    

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

First $100,000,000                            0.60%
Next $150,000,000                             0.45%
Next $250,000,000                             0.40%
Next $150,000,000                             0.35%
Amount over $650,000,000                      0.30%

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


                                       28
<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 of
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 its 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 the 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 reckless disregard by the Adviser of its obligations and duties under
the Advisory .

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 Advisory
Agreement is no longer in effect, the Fund (to the extent that it lawfully can)
will cease to use such a 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 either party or by vote of a majority of the outstanding
voting securities of the Fund and will terminate automatically if assigned.
    

For the years ended May 31, 1995, 1996 and 1997 the Adviser received a fee of
$2,007,777, $2,313,339 and $2,830,885, respectively.

   
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 May 31, 1997, the Fund paid the
Adviser $132,910 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 CONTRACT

   
The Fund has a Distribution Agreement with John Hancock Funds. Under the
agreement, John Hancock Funds is obligated to use its best efforts to sell
shares of each class on behalf of the Fund. Shares of the Fund are also sold by
selected broker-dealers (the "Selling Brokers") which have entered into selling
agency agreements with John Hancock Funds. John Hancock Funds accepts orders for
the purchase of the shares of the Fund which are continually offered at net
asset value next determined, plus any applicable sales charge, if any. In
connection with the sale of Fund shares, John Hancock Funds and Selling Brokers
receive compensation from a sales charge imposed, in the case of Class A shares
at the time of sale. In the case of Class B or Class C shares, the broker
receives compensation immediately but John Hancock Funds is compensated on a
deferred basis. John Hancock Funds may pay extra compensation to financial
services firms selling large amounts of fund shares. This compensation would be
calculated as a percentage of fund shares sold by the firm.
    

Total underwriting commissions for sales of the Fund's Class A shares for the
fiscal years ended May 31, 1996 and 1997 were $2,095,227 and $2,275,918,
respectively. Of such amounts, $232,623 and $266,508, respectively, were
retained by John Hancock Funds in 1996 and 1997. The remainder of the
underwriting commissions were reallowed to dealers.

   
The Fund's  Trustees  adopted  Distribution  Plans with respect to each class of
shares (the "Plans"), pursuant to Rule 12b-1 under the Investment Company Act of
1940.  Under the Plans,  the Fund will pay  distribution  and service fees at an
aggregate  annual  rate of up to 0.30% for Class A shares  and 1.00% for Class B
and Class C shares of the Fund's average daily net assets attributable to shares
of that class.  However,  the  service  fee will not exceed  0.25% of the Fund's
average daily net assets  attributable to each class of shares. The distribution
fees will be used to reimburse John Hancock Funds for its distribution expenses,
including  but not limited to: (i) initial  and ongoing  sales  compensation  to
Selling  Brokers and others engaged in the sale of Fund shares,  (ii) marketing,
promotional and overhead  expenses  incurred in connection with the distribution
of Fund  shares,  and (iii)  with  respect  to Class B and Class C shares  only,
interest expenses on unreimbursed  distribution  expenses. The service fees will
be used to  compensate  Selling  Brokers and others for  providing  personal and
account  maintenance  services to  shareholders.  In the event that John Hancock
Funds is not fully  reimbursed for payments it makes or expenses it incurs under
the Class A Plan,  these  expenses will not be carried  beyond one year from the
date they were  incurred.  Unreimbursed  expenses  under the Class B and Class C
Plans will be carried  forward  together  with  interest on the balance of these
unreimbursed  expenses.  The Fund does not treat  unreimbursed  expenses  under
Class B and Class C Plans as a liability  of the Fund,  because the Trustees may
terminate the Class B and/or Class C Plans at any time. For the period ended May
31, 1997 an aggregate of  $5,664,567  of  distribution  expenses or 2.11% 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
12b-1 fees in prior periods.  Class C shares did not commence  operations  until
May 1, 1998; therefore, there are no unreimbursed expenses to report.
    

The Plans were approved by a majority of the voting securities of the Fund. The
Plans and all amendments were approved by 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 each these 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.


                                       30
<PAGE>

   
The Plans provide that they will continue in effect only so long as its
continuance is approved at least annually by a majority of both the Trustees and
the Independent Trustees. The Plans provide that they may be terminated without
penalty (a) by a vote of a majority of the Independent Trustees, or (b) by a
vote of a majority of the Fund's outstanding shares of the applicable class in
each case 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 the Plan. Each
Plan provides that no material amendment to the Plans will be effective unless
it is approved by a majority vote of the Trustees and the Independent Trustees
of the Fund. The holders of Class A, Class B and Class C shares have exclusive
voting rights with respect to the Plan applicable to their respective class of
shares. In adopting the Plans, the Trustees concluded that, in their judgment,
there is a reasonable likelihood that the Plans will benefit the holders of the
applicable class of shares of the Fund.
    

Amounts paid to John Hancock Funds by any class of shares of the Fund will not
be used to pay the expenses incurred with respect to any other class of shares
of the Fund; provided, however, that expenses attributable to the Fund as a
whole will be allocated, to the extent permitted by law, according to a formula
based upon gross sales dollars and/or average daily net assets of each such
class, as may be approved from time to time by vote of a majority of the
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 May 31, 1997, the Fund paid John Hancock Funds the
following amounts of expenses in connection with their services for the Fund.
Class C shares did not commence operations until May 1, 1998; therefore, there
are no expenses to report.
    

                                  Expense Items

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 


                                       31
<PAGE>

determine valuations for normal institutional size trading units of debt
securities without exclusive reliance upon quoted prices.

Equity securities traded on a principal exchange or NASDAQ National Market
Issues are generally valued at last sale price on the day of valuation.
Securities in the aforementioned category for which no sales are reported and
other securities traded over-the-counter are generally valued at the last
available bid price.

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.

Foreign securities are valued on the basis of quotations from the primary market
in which they are traded. Any assets or liabilities expressed in terms of
foreign currencies are translated into U.S. dollars by the custodian bank based
on London currency exchange quotations as of 5:00 p.m. London time (12:00 noon,
New York time) on the date of any determination of a Fund's NAV. If quotations
are not readily available, or the value has been materially affected by events
occurring after the closing of a foreign market, assets are valued by a method
that the Trustees believe accurately reflects fair value.

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.
On any day an international market is closed and the New York Stock Exchange is
open, any foreign securities will be valued at the prior day's close with the
current day's exchange rate. Trading of foreign securities may take place on
Saturdays and U.S. business holidays on which the Fund's NAV is not calculated.
Consequently, the Fund's portfolio securities may trade and the NAV of the
Fund's redeemable securities may be significantly affected on days when a
shareholder has no access to the Fund.

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 they
will only be issued for full shares. The Trustees reserve the right to change or
waive a 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 the 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
of the Fund, 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 Charges. Class A shares may be offered without a front-end sales
charge or CDSC to various individuals and institutions as follows:


                                       32
<PAGE>

      o Any state, county or any instrumentality, department, authority, or
      agency of these entities that is prohibited by applicable investment laws
      from paying a sales charge or commission when it purchases shares of any
      registered investment management company.*

      o A bank, trust company, credit union, savings institution or other
      depository institution, its trust departments or common trust funds if it
      is purchasing $1 million or more for non-discretionary customers or
      accounts.*

      o A Trustee or officer of the Trust; a Director or officer of the Adviser
      and its affiliates or Selling Brokers; employees or sales representatives
      of any of the foregoing; retired officers, employees or Directors of any
      of the foregoing; a member of the immediate family (spouse, children,
      grandchildren, mother, father, sister, brother, mother-in- law,
      father-in-law) of any of the foregoing; or any fund, pension, profit
      sharing or other benefit plan for the individuals described above.

      o A broker, dealer, financial planner, consultant or registered investment
      advisor that has entered into an 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.

      o 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.

      o A member of an approved affinity group financial services plan.*

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

      o 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.

      o Existing full service clients of the Life Company who were group annuity
      contract holders as of September 1, 1994, and participant directed defined
      contribution plans with at least 100 eligible employees at the inception
      of the Fund account, 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 of the Fund 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.


                                       33
<PAGE>

* For investments made under these provisions, John Hancock Funds may make a
payment out of its own resources to the Selling Broker in an amount not to
exceed 0.25% of the amount invested.

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 then being invested but
also the 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.

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. The reduced sales charges are also applicable to
investments in shares made over a specified period 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 specified 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 IRAs, SEP, SARSEP, 401(k), 403(b)
(including TSAs), SIMPLE IRA, SIMPLE 401(k), Money Purchase Pension, Profit
Sharing and Section 457 plans. Such an investment (including accumulations and
combinations) 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 escrow 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 


                                       34
<PAGE>

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 AND CLASS C SHARES

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

Contingent Deferred Sales Charge. Class B and Class C shares which are redeemed
within six years or one year of purchase, respectively, will be subject to a
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 or Class C 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 and Class C shares are not available to full-service defined
contribution 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 the purpose of determining the number of
years from the time of any payment for the purchase of both Class B and Class C
shares, all payments during a month will be aggregated and deemed to have been
made on the first day of the month.

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


                                       35
<PAGE>

   
      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 and Class C shares, such as the payment of compensation to selected
Selling Brokers for selling Class B and Class C shares. The combination of the
CDSC and the distribution and service fees facilitates the ability of the Fund
to sell the Class B and Class C shares without a sales charge being deducted at
the time of the purchase.

Waiver of Contingent Deferred Sales Charge. The CDSC will be waived on
redemptions of Class B shares and Class C shares and of Class A shares that are
subject to 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
      companies.

*     Redemptions due to death or disability.

*     Redemptions made under the Reinstatement Privilege, as described in "Sales
      Charge Reductions and Waivers" of the Prospectus.

   
*     Redemptions of Class B and Class C shares made under a periodic withdrawal
      plan, as long as your annual redemptions do not exceed 12% of your account
      value, including reinvested dividends, at the time you established your
      periodic withdrawal plan and 12% of the value of subsequent investments
      (less redemptions) in that account at the time you notify Investor
      Services. (Please note, this waiver does not apply to periodic withdrawal
      plan redemptions of Class A shares that are subject to a CDSC.)
    

*     Redemptions by Retirement plans participating in Merrill Lynch servicing
      programs, if the Plan has less than $3 million in assets or 500 eligible
      employees at the date the Plan Sponsor signs the Merrill Lynch
      Recordkeeping Service Agreement. See you Merrill Lynch financial
      consultant for further information.

TSA, 457, 403(b), 401(k), Money Purchase Pension Plan, Profit-Sharing Plan and
other plans as described in the Internal Revenue Code) unless otherwise noted.
    

*     Redemptions made to effect mandatory distributions under the Internal
      Revenue Code.

*     Returns of excess contributions made to these plans.


                                       36

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 readily marketable
portfolio securities as prescribed by the Trustees. When the shareholder sells
portfolio securities received in this fashion, the shareholder will incur a


                                       38
<PAGE>

brokerage charge. 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 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 Sincemay result in realization of gain or loss
for purposes of Federal, state and local income taxes. The maintenance of a
Systematic Withdrawal Plan concurrently with purchases of additional shares of
the Fund could be disadvantageous to a shareholder because of the initial sales
charge payable on purchases of Class A shares and the CDSC imposed on
redemptions of Class B and Class C shares and because redemptions are taxable
events. Therefore, a shareholder should not purchase shares at the same time
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.
    


                                       39
<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 MAA 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 processing date of any investment.

Reinstatement or Reinvestment Privilege. If Signature Services is notified prior
to reinvestment, a shareholder who has redeemed shares of the Fund 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 in shares of any of the other John Hancock mutual funds, 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 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. As of the date of this Statement of Additional
Information, the Trustees have authorized shares of the Fund and one other
series. The Declaration of Trust also authorizes the Trustees to classify and
reclassify the shares of the Fund, or any new series of the Fund, into one or
more classes. As of the date of this Statement of Additional Information, the
Trustees have authorized the issuance of three classes of shares of the Fund,
designated as Class A, Class B and Class C.
    

The shares of the Fund represent an equal proportionate interest in the
aggregate net assets attributed to that class of the Fund. Holders of each
class of shares each have certain exclusive voting rights on matters relating to
their respective Rule 12b-1 distribution plans. The different classes of the
Fund may bear different expenses relating to the cost of holding shareholder
meetings necessitated by the exclusive voting rights of any class of shares.

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

In the event of liquidation, shareholders of each class are entitled to share
pro rata in the net assets of the Fund available for distribution to these
shareholders. Shares entitle their holders to one vote per share, are freely
transferable and have no preemptive, subscription or conversion rights. When
issued, shares are fully paid and non-assessable, 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 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. The Declaration of Trust
also provides that no series of the Trust shall be liable for the liabilities of
any other series. Liability is therefore limited to circumstances in which 


                                       41
<PAGE>

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 credit card checks. Use of 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.

TAX STATUS

   
Each series of the Trust, including the Fund, is treated as a separate entity
for tax purposes. The Fund has qualified as a "regulated investment company"
under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code")
and intends to continue 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 taxable income
(including net realized capital gains) which is distributed to shareholders in
accordance with the timing requirements of the Code.

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

Distributions 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. 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 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, other than those gains and losses included in
computing net capital gain, after reduction by deductible expenses.) As a result
of federal tax legislation enacted on August 5, 1997 (the "Act"), gain
recognized after May 6, 1997 from the sale of a capital asset is taxable to
individual (noncorporate) investors at different maximum federal income tax
rates, depending generally upon the tax holding period for the asset, the
federal income tax bracket of the taxpayer, and the dates the asset was acquired
and/or sold. The Treasury Department has issued guidance under the Act that
enables the Fund to pass through to its shareholders the benefits of the capital
gains rates enacted in the Act. Shareholders should consult their own tax
advisers on the correct application of these new rules in their particular
circumstances. 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. 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.

Foreign  exchange  gains and  losses  realized  by the Fund in  connection  with
certain  transactions  involving foreign  currency-denominated  debt securities,
certain foreign currency options,  foreign currency forward  contracts,  foreign
currencies,  or payables or receivables  denominated  in a foreign  currency are
subject to Section 988 of the Code, which generally causes such gains and losses
to be treated as ordinary  income and losses and may affect the  amount,  timing
and  character  of  distributions  to  shareholders.   Transactions  in  foreign
currencies  that are not directly  related to the Fund's  investment in stock or
securities, including speculative currency positions could under future Treasury
regulations produce income not among the types of "qualifying income" from which
the Fund must derive at least 90% of its gross income for each taxable  year. If
the net foreign  exchange loss for a year treated as ordinary loss under Section
988 were to exceed the Fund's investment company taxable income computed without
regard to such loss, the resulting overall ordinary loss for such year would not
be deductible by the Fund or its shareholders in future years.
    

The Fund may be subject to withholding and other taxes imposed by foreign
countries with respect to its investments in foreign securities. Some tax
conventions between certain countries and the U.S. may reduce or eliminate such
taxes. Investors may be entitled to claim U.S. foreign tax credits or deductions
with respect to foreign income taxes or certain other foreign taxes ("qualified
foreign taxes"), paid by the Fund, subject to certain holding period
requirements and limitations contained in the Code, if the Fund so elects. If
more than 50% of the value of the Fund's total assets at the close of any
taxable year consists of stock or securities of foreign corporations, the Fund
may file an election with the Internal Revenue Service pursuant to which
shareholders of the Fund will be required to (i) include in ordinary gross
income (in addition to taxable dividends and distributions actually received)
their pro rata shares of qualified foreign taxes paid by the Fund even though
not actually received by them, and (ii) treat such respective pro rata portions
as qualified foreign income taxes paid by them.

If the Fund makes this election, shareholders may then deduct such pro rata
portions of qualified foreign taxes in computing their taxable incomes, or,
alternatively, use them as foreign tax credits, subject to applicable
limitations, against their U.S. Federal income taxes. Shareholders who do not
itemize deductions for Federal income tax purposes will not, however, be able to
deduct their pro rata portion of qualified foreign taxes paid by the Fund,
although such shareholders will be required to include their share of such taxes
in gross income. Shareholders who claim a foreign income tax credit for such
foreign taxes may be required to treat a portion of dividends received from the
Fund as a separate category of income for purposes of computing the limitations
on the foreign tax credit. Tax-exempt shareholders will ordinarily not benefit
from this election. Each year (if any) that the Fund files the election
described above, its shareholders will be notified of the amount of (i) each
shareholder's pro rata share of qualified foreign income taxes paid by the Fund
and (ii) the portion of Fund dividends which represents income from each foreign
country. If the Fund does not satisfy the 50% requirement described above or
otherwise does not make the election, the Fund will deduct the foreign taxes it
pays in determining the amount it has available for distribution to
shareholders, and shareholders will not include these foreign taxes in their
income, nor will they be entitled to any tax deductions or credits with respect
to such taxes.

   
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 and/or engage in options, futures or forward transactions
that will generate capital gains or engage in certain other transactions or
derivatives. 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 or undistributed taxable income of the Fund.
Consequently, subsequent distributions on those shares from such appreciation or
income may be taxable to such investor even if the net asset value of the
investor's shares is, as a result of the 
    


                                       43
<PAGE>

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  may 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  Class A 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 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.  Also,  future  Treasury  Department  guidance  issued to
implement  the  Act  may  contain  additional  rules  for  determining  the tax
treatment  of sales of Fund  shares  held for  various  periods,  including  the
treatment  of  losses on sales of  shares  held for six  months or less that are
recharacterized as long-term capital losses, as described above.
    

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, as computed for Federal income tax purposes, 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 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
realized 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 as such
to shareholders. The Fund has $29,587,682 of capital loss carry-forwards, which
expire as follows: May 31, 1999-$8,553,157 May 31, 2002-$454,810, May 31,
2003-$20,312,807 and May 31, 2004-$266,908 available to offset future net
capital gains.
    


                                       44
<PAGE>

Only a small portion, if any, of the distributions from the Fund may qualify for
the dividends-received deduction for corporations, subject to the limitations
applicable under the Code. The qualifying portion is limited to properly
designated distributions attributed to dividend income (if any) the Fund
receives from certain stock in U.S. domestic corporations and the deduction is
subject to holding period requirements and debt-financing limitations under the
Code.

   
Investment in debt obligations that are at risk of or in default presents
special tax issues for any fund that holds these obligations. 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 if it acquires such obligations
in order to reduce the risk of distributing insufficient income to preserve its
status as a regulated investment company and to seek to avoid becoming subject
to Federal income or excise tax.
    

Different tax treatment, including penalties on certain excess contributions and
deferrals, certain pre-retirement and post-retirement distributions and certain
prohibited transactions, is accorded to accounts maintained as qualified
retirement plans. Shareholders should consult their tax advisers for more
information.

   
The Fund is required to accrue income on any debt securities that have more than
a de minimus amount of original issue discount (or debt securities acquired at a
market  discount,  if the Fund  elects  to  include  market  discount  in income
currently) prior to the receipt of the corresponding cash payments.  The mark to
market or  constructive  sale  rules  applicable  to certain  options,  futures,
forwards,  short  sales  or other  transactions  may  also  require  the Fund to
recognize  income or gain  without a concurrent  receipt of cash.  Additionally,
some countries  restrict  repatriation which may make it difficult or impossible
for the Fund to obtain  cash  corresponding  to its  earnings or assets in those
countries.  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 cash, to satisfy these distribution requirements.
    

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 intangible property taxes, the
value of its assets is attributable to) certain U.S. Government obligations,
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 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 


                                       45
<PAGE>

shareholder is subject to backup withholding as a result of failure to report
interest or dividend income. The Fund may refuse to accept an application that
does not contain any required taxpayer identification number or certification
that the number provided is correct. If the backup withholding provisions are
applicable, any such distributions and proceeds, whether taken in cash or
reinvested in shares, will be reduced by the amounts required to be withheld.
Any amounts withheld may be credited against a shareholder's U.S. federal income
tax liability. Investors should consult their tax advisers about the
applicability of the backup withholding provisions.

The Fund may be required to account for its transactions in forward rolls or
swaps, caps, floors and collars in a manner that, under certain circumstances,
may limit the extent of its participation in such transactions. Additionally,
the Fund may be required to recognize gain, but not loss, if a swap or other
transaction is treated as a constructive sale of an appreciated financial
position in the Fund's portfolio. The Fund may have to sell portfolio securities
under disadvantageous circumstances to generate cash, or borrow cash, to satisfy
these distribution requirements.

   
Limitations imposed by the Code on regulated investment companies like the Fund
may restrict the Fund's ability to enter into options, future, foreign currency
positions, and foreign currency forward contracts.

Certain options, futures and forward foreign currency contracts 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 (or, in the case of foreign currency
contracts, as ordinary income or loss) and timing of some gains and losses
realized by the Fund. Additionally, the Fund may be required to recognize gain,
but not loss, if an option, short sale or other transaction 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,
futures or forward 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 gains. Certain of such 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, futures and forward contracts 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 classes
of investors, such as tax-exempt entities, insurance companies, and financial
institutions. 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 November 30, 1997, the Fund's annualized yields for
Class A and Class B shares of the Fund were 7.50 % and 7.15%, respectively.
Class C shares of the Fund commenced operations on May 1, 1998; therefore, there
is no yield to report. The average annual total returns on Class A shares of the
Fund for the 1 year, 5 year and 10 year period ended November 30, 1997 were
6.19%, 9.33% and 8.71%, respectively.

The total returns for the 1-year and since inception on October 4, 1993 periods
for Class B shares were 5.42% and 8.55%, respectively. Class C shares of the
Fund commenced operations on May 1, 1998; therefore, there is no average annual
total return to report.
    

The Fund advertises 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 and annualizing the result. While this is the standard
accounting method for calculating yield, it does not reflect the fund's actual
bookkeeping; as a result, the income reported or paid by the Fund may be
different. The Fund's yield is computed according to the following standard
formula:

                     Yield = 2 ( [ ( a-b/cd ) + 1 ] ^6 - 1)

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).

The Fund's total return is computed by finding the average annual compounded
rate of return over the 1-year and life-of-fund periods that would equate the
initial amount invested to the ending redeemable value according to the
following formula:

                             T = ((ERV/P)^(1/n)) - 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.


                                       47
<PAGE>

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

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

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

Performance rankings and ratings reported periodically in national financial
publications such as MONEY MAGAZINE, FORBES, BUSINESS , THE WALL STREET JOURNAL,
MICROPAL, INCnc., MORNINGSTAR, STANGER'S and BARRON'S may also be utilized.

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 officers of the Fund
pursuant to recommendations made by an investment committee of the Adviser,
which consists of officers and directors of the Adviser and affiliates, and
officers 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 officers of the Fund, 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 maker reflect a "spread." Debt
securities are generally traded on a net 


                                       48
<PAGE>

basis through dealers acting for their own account as principals and not as
brokers; no brokerage commissions are payable on such transactions.

In the U.S. and in some other countries, debt securities are traded principally
in the over-the-counter market on a net basis through dealers acting for their
own account and not as brokers. In other countries, both debt and equity
securities are traded on exchanges at fixed commission rates. Commissions on
foreign transactions are generally higher than the negotiated commission rates
available in the U.S. There is generally less government supervision and
regulation of foreign stock exchanges and broker-dealers than in the U.S.

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

To the extent consistent with the foregoing, the Fund will be governed in the
selection of brokers and dealers, and the negotiation of brokerage commission
rates and dealer spreads, by the reliability and quality of the services,
including primarily the availability and value of research information and to a
lesser extent statistical assistance furnished to the Adviser of the Fund, and
their value and expected contribution to the performance of the Fund. It is not
possible to place a dollar value on information and services to be received from
brokers and dealers, since it is only supplementary to the research efforts of
the Adviser. The receipt of research information is not expected to reduce
significantly the expenses of the Adviser. The research information and
statistical assistance furnished by brokers and dealers may benefit the Life
Company or other advisory clients of the Adviser, and, conversely, brokerage
commissions and spreads paid by other advisory clients of the Adviser may result
in research information and statistical assistance beneficial to the Fund. The
Fund will make no commitment to allocate portfolio transactions upon any
prescribed basis. While the Fund'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 years ended on May 31, 1995, 1996 and
1997, the Fund paid negotiated brokerage commissions in the amount of $2,751,
$11,500 and $4,000, 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 such price is
reasonable in light of the services provided and to such policies as the
Trustees may adopt from time to time. During the fiscal year ended May 31,
19967, the Fund directed no 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. ("Distributors"), a broker-dealer
("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 year ending May 31, 1997, 1996 and 1995, the Fund did not execute any
portfolio transactions with Affiliated Brokers.


                                       49
<PAGE>

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 clearing broker for another firm, and any customers of the Affiliated
Broker not comparable to the Fund as determined by a majority of the Trustees
who are not interested persons (as defined in the Investment Company Act) of the
Fund, the Adviser or the Affiliated Broker. Because the Adviser, which is
affiliated with the Affiliated Brokers, has, as an investment adviser to the
Fund, the obligation to provide investment management services, which include
elements of research and related investment skills, such research and related
skills will not be used by the Affiliated 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 as the Fund. When these clients buy or sell the same securities
at substantially the same time, the Adviser may average the transactions 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 securities to be
sold or purchased for the Fund with those to be sold or purchased for other
clients managed by it in order to obtain best execution.

TRANSFER AGENT SERVICES

   
John Hancock Signature Services, Inc., 1 John Hancock Way, Suite 1000, Boston,
MA 02217-1000, a wholly-owned indirect subsidiary of the Life Company, is the
transfer and dividend paying agent for the Fund. The Fund pays an annual fee of
$20.00 for each Class A shareholder account, $22.50 for each Class B shareholder
account and $20.50 for each Class C shareholder account. The Fund pays certain
out-of-pocket expenses and 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, MA 02116. Under the custodian agreement, Investors Bank & Trust Company
performs custody, portfolio and fund accounting services.

   
INDEPENDENT AUDITORS

The independent auditors of the Fund are Price Waterhouse LLP, 160 Federal

                                    APPENDIX

As described in the Statement of Additional Information, the debt securities
offering the high current income sought by the Fund are ordinarily in the lower
rating categories (that its, rated Baa or lower by Moody's or BBB or lower by
Standard & Poor's, or are unrated).

Moody's describes its lower ratings for corporate bonds as follows:

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

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

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

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

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

Standard & Poor's describes its lower ratings for corporate bonds as follows:

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

Debt rated BB, B, CCC, or CC is regarded, on balance, as predominantly
speculative with respect to the issuer's capacity to pay interest and repay
principal in accordance with the terms of the obligations. 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.

Moody's describes its three highest ratings for commercial paper as follows:

Issuers rated P-1 (or related supporting institutions) have a superior capacity
for repayment of short-term promissory obligations. P-1 repayment capacity will
normally be evidenced by the following characteristics: (1) leading market
positions in well-established industries; (2) high rates of return on funds
employed; (3) conservative capitalization structures with moderate reliance on
debt and ample asset protection; (4) broad margins in earnings coverage of fixed
financial charges and high internal 


                                       A-1
<PAGE>

cash generation; and (5) well established access to a range of financial markets
and assured sources of alternate liquidity.

Standard & Poor's describes its three highest ratings for commercial paper as
follows:

A-1. This designation indicates that the degree of safety regarding timely
payment is very strong.

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

A-3. Issues carrying this designation have a satisfactory capacity for timely
payment. They are, however, somewhat more vulnerable to the adverse effects of
changes in circumstances than obligations carrying the higher designations.

Issuers rated P-2 (or related supporting institutions) have a strong capacity
for repayment of short-term promissory obligations. This will normally be
evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

Issuers rated P-3 (or supporting institutions) have an acceptable ability for
repayment of senior short-term obligations. The effect of industry
characteristics and market compositions may be more pronounced. Variability in
earnings and profitability may result in changes in the level of debt protection
measurements and may require relatively high financial leverage. Adequate
alternate liquidity is maintained.

ORGANIZATION OF THE FUND

The Fund is a diversified open-end investment management company organized as a
Massachusetts business trust under the laws of The Commonwealth of
Massachusetts. The Fund was organized on April 16, 1986. The Trustees have
authority to issue an unlimited number of shares of beneficial interest of
separate series without par value.

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 goals,
strategies and risks discussed in the Prospectus. There is no assurance that the
Fund will achieve its investment objective.
    

The Fund's investment objective is to provide as high a level of income as is
consistent with long-term total return by investing in securities issued,
guaranteed or otherwise backed by the United States government, its agencies or
instrumentalities ("Government Securities"). The Adviser believes that a high
current income consistent with long-term total return may be derived from: (i)
interest income from Government Securities; (ii) income from premiums from
expired put and call options on Government Securities written by the Fund; (iii)
net gains from closing purchase and sale transactions with respect to options on
Government Securities; and (iv) net gains from sales of portfolio securities on
exercise of options or otherwise.

   
Since interest yields on Government Securities and opportunities to realize net
gains from options transactions may vary from time to time because of general
economic and market conditions and many other factors, it is anticipated that
the Fund's share price and yield will fluctuate.
    

Government Securities. Under normal circumstances, the Fund will invest at least
65% of its total assets in Government Securities. The Government Securities that
may be purchased by the Fund include, but are not limited to:

U.S. Treasury Securities. The Fund may invest in U.S. Treasury securities,
including Bills (maturities of one year or less), Notes (maturities of one to
ten years), Bonds (generally maturities of greater than ten years) and other
debt securities issued by the U.S. Treasury. These instruments are direct
obligations of the U.S. Government and differ primarily in their interest rates,
the lengths of their maturities and the times of their issuance.

Securities Issued or Guaranteed by U.S. Government Agencies and
Instrumentalities. The Fund may also invest in securities issued by agencies of
the U.S. Government or instrumentalities established or sponsored by the U.S.
Government. The obligations, including those which are guaranteed by Federal
agencies or instrumentalities, may or may not be backed by the "full faith and
credit" of the United States. In the case of securities not backed by the full
faith and credit of the United States, the Fund must look principally to the
agency issuing or guaranteeing the obligation for ultimate repayment and may not
be able to assert a claim against the United States itself in the event the
agency or instrumentality does not meet its commitments. Securities in 


                                       2
<PAGE>

which the Fund may invest but which are not backed by the full faith and credit
of the United States include but are not limited to obligations of the Tennessee
Valley Authority, the Federal Home Loan Mortgage Corporation ("FHLMC") and the
United States Postal Service, each of which has the right to borrow from the
United States Treasury to meet its obligations, and obligations of the Federal
Farm Credit System, the Federal National Mortgage Association ("FNMA") and the
Federal Home Loan Banks, the obligations of which may only be satisfied by the
individual credit of the issuing agency. Obligations of the Government National
Mortgage Association ("GNMA"), the Farmers Home Administration and the
Export-Import Bank are backed by the full faith and credit of the United States.

Securities of International Bank for Reconstruction and Development

The Fund may also purchase obligations of the International Bank for
Reconstruction and Development ("World Bank"), which, while technically not a
U.S. Government agency or instrumentality, has the right to borrow from the
participating countries, including the United States.

The Fund may invest in Government Securities of all maturities: short-term,
intermediate-term and long-term.

The Fund may, for purposes of liquidity and flexibility, place up to 35% of its
assets in investment-grade (equivalent to the top four bond rating categories of
a nationally recognized securities rating organization such as Standard & Poor's
Rating Group ("Standard & Poor's") or Moody's Investor's Service, Inc.
("Moody's")) short-term securities, including debt securities of corporations,
certificates of deposit of domestic banks, or repurchase agreements with respect
to Government Securities, including repurchase agreements that mature in more
than seven days. In the event these securities are subsequently downgraded below
such ratings, the Adviser will consider this event in its determination of
whether the Fund should continue to hold the securities. The Fund may also
invest in collateralized mortgage-backed obligations that are issued or
sponsored by a government agency. In abnormal market conditions, it may invest
more assets in these securities as a defensive tactic. See Appendix A to this
Statement of Additional Information for a description of the various ratings of
investment grade debt securities.

Mortgage-Related Securities. The Fund may invest in mortgage-backed securities,
including those representing an undivided ownership interest in a pool of
mortgage loans, e.g., securities of the GNMA and pass-through securities issued
by the FHLMC and FNMA.

GNMA Certificates. Certificates of the GNMA ("GNMA Certificates") are
mortgage-backed securities, which evidence an undivided interest in a pool of
mortgage loans. GNMA Certificates differ from bonds in that the principal is
paid back monthly by the borrower over the term of the loan rather than returned
in a lump sum at maturity. GNMA Certificates that the Fund purchases are the
"modified pass-through" type. "Modified pass-through" GNMA Certificates entitle
the holder to receive a share of all interest and principal payments paid and
owed on the mortgage pool, net of fees paid to the "issuer" and GNMA, regardless
of whether or not the mortgagor actually makes the payment.

GNMA Guarantee. The National Housing Act authorizes GNMA to guarantee the timely
payment of principal and interest on securities backed by a pool of mortgages
insured by the Federal Housing Administration ("FHA") or the Farmers' Home
Administration ("FMHA"), or guaranteed by the Veterans Administration ("VA").
The GNMA guarantee is backed by the full 


                                       3
<PAGE>

faith and credit of the United States. The GNMA is also empowered to borrow
without limit from the U.S. Treasury if necessary to make any payments required
under its guarantee.

Life of GNMA Certificates. The average life of a GNMA Certificate is likely to
be substantially less than the original maturity of the mortgage pools
underlying the securities. Prepayments of principal by mortgagors and mortgage
foreclosures will usually result in the return of the greater part of principal
investment long before the contractual maturity of the mortgages in the pool.
Foreclosures impose no risk to principal investment because of the GNMA
guarantee. Because they represent the underlying mortgages, GNMA Certificates
may not be an effective means of locking in long-term interest rates due to the
need for the Fund to reinvest scheduled and unscheduled principal payments. At
the time principal payments or prepayments are received by the Fund, prevailing
interest rates may be higher or lower than the current yield of the Fund's
portfolio.

Statistics published by the FHA indicate that the average life of single-family
dwelling mortgages with 25 to 30-year maturities, the type of mortgages backing
the vast majority of GNMA Certificates, is approximately 12 years. However,
because prepayment rates of individual mortgage pools vary widely, it is not
possible to predict accurately the average life of a particular issue of GNMA
Certificates.

Yield Characteristics of GNMA Certificates. The coupon rate of interest on GNMA
Certificates is lower than the interest rate paid on the VA-guaranteed or
FHA-insured mortgages underlying the Certificates, by the amount of the fees
paid to GNMA and the issuer.

The coupon rate by itself, however, does not indicate the yield which will be
earned on GNMA Certificates. First, GNMA Certificates may be issued at a premium
or discount, rather than at par, and, after issuance, GNMA Certificates may
trade in the secondary market at a premium or discount. Second, interest is
earned monthly, rather than semiannually as with traditional bonds; monthly
compounding raises the effective yield earned. Finally, the actual yield of a
GNMA Certificate is influenced by the prepayment experience of the mortgage pool
underlying it. For example, if the higher- yielding mortgages from the pool are
prepaid, the yield on the remaining pool will be reduced. Prepayments of
principal by mortgagors (which can be made at any time without penalty) may
increase during periods when interest rates are falling.

FHLMC Securities. The FHLMC was created in 1970 through enactment of Title III
of the Emergency Home Finance Act of 1970. Its purpose is to promote development
of a nationwide secondary market in conventional residential mortgages.

The FHLMC issues two types of mortgage pass-through securities, mortgage
participation certificates ("PCs") and guaranteed mortgage certificates
("GMCs"). PCs resemble GNMA Certificates in that each PC represents a pro rata
share of all interest and principal payments made and owed on the underlying
pool. The FHLMC guarantees timely payment of interest on PCs and the full return
of principal.

GMC's also represent a pro rata interest in a pool of mortgages. However, these
instruments pay interest semiannually and return principal once a year in
guaranteed minimum payments.

FNMA Securities. The FNMA was established in 1938 to create a secondary market
in mortgages insured by the FHA.


                                       4
<PAGE>

FNMA Issued Guaranteed Mortgage Pass-through Certificates ("FNMA Certificates").
FNMA Certificates resemble GNMA Certificates in that each FNMA Certificate
represents a pro rata share of all interest and principal payments made and owed
on the underlying pool. FNMA guarantees timely payment of interest on FNMA
Certificates and the full return of principal.

Collateralized Mortgage-Backed Obligations ("CMO's"). CMOs are
fully-collateralized bonds which are the general obligations of the issuer
thereof, either the U.S. Government or a U.S. Government instrumentality. Such
bonds generally are secured by an assignment to a trustee (under the indenture
pursuant to which the bonds are issued) of collateral consisting of a pool of
mortgages. Payments with respect to the underlying mortgages generally are made
to the trustee under the indenture. Payments of principal and interest on the
underlying mortgages are not passed through to the holders of the CMOs as such
(i.e. the character of payments of principal and interest is not passed through,
and therefore payments to holders of CMOs attributable to interest paid and
principal repaid on the underlying mortgages do not necessarily constitute
income and return of capital, respectively, to such holders), but such payments
are dedicated to payment of interest on and repayment of principal of the CMOs.
CMOs often are issued in two or more classes with varying maturities and stated
rates of interest. Because interest and principal payments on the underlying
mortgages are not passed through to holders of CMOs, CMOs of varying maturities
may be secured by the same pool of mortgages, the payments on which are used to
pay interest on each class and to retire successive maturities in sequence.
Unlike other mortgage-backed securities (discussed above), CMOs are designed to
be retired as the underlying mortgages are repaid. In the event of prepayment on
such mortgages, the class of CMO first to mature generally will be paid down.
Therefore, although in most cases the issuer of CMOs will not supply additional
collateral in the event of such prepayment, there will be sufficient collateral
to secure CMOs that remain outstanding.

Inverse Floating Rate Securities. The Fund may invest in inverse floating rate
securities. It is the current intention of the Fund to invest no more than 5% of
its net assets in inverse floating rate securities. The interest rate on an
inverse floating rate security resets in the opposite direction from the market
rate of interest to which the inverse floating rate security is indexed. An
inverse floating rate security may be considered to be leveraged to the extent
that its interest rate varies by a multiple of the index rate of interest. A
higher degree of leverage in the inverse floating rate security is associated
with greater volatility in the market value of such security.

The inverse floating rate securities that the Fund may invest in include but are
not limited to, an inverse floating rate class of a government agency issued CMO
and a government agency issued yield curve note. Typically, an inverse floating
rate class of a CMO is one of two components created from the cash flows from a
pool of fixed rate mortgages. The other component is a floating rate security in
which the amount of interest payable varies directly with a market interest rate
index. A yield curve note is a fixed income security that bears interest at a
floating rate that is reset periodically based on an interest rate benchmark.
The interest rate resets on a yield curve note in the opposite direction from
the interest rate benchmark.

Mortgage-backed securities have stated maturities of up to thirty years when
they are issued, depending upon the length of the mortgages underlying the
securities. In practice, however, unscheduled or early payments of principal and
interest on the underlying mortgages may make the securities' effective maturity
shorter than this, and the prevailing interest rates may be higher or lower than
the current yield of the Fund's portfolio at the time the Fund receives these
payments for reinvestment. Mortgage-backed securities may have less potential
for capital appreciation than comparable fixed-income securities due to the
likelihood of increased prepayments of mortgages as interest rates decline. If
the Fund buys mortgage-backed securities 


                                       5
<PAGE>

at a premium, mortgage foreclosures and prepayments of principal by mortgagors
(which may be made at any time without penalty) may result in some loss of the
Fund's principal investment, to the extent of the premium paid.

In a rising interest rate environment, a declining prepayment rate will extend
the average life of many mortgage-backed securities. Extending the average life
of a mortgage-backed security increases the risk of depreciation due to future
increases in market interest rates.

Repurchase Agreements. 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 and the expense of enforcing its rights.

Reverse Repurchase Agreements. The Fund may also enter into reverse repurchase
agreements which involve the sale of U.S. Government securities held in its
portfolio to a bank with an agreement that the Fund will buy back the securities
at a fixed future date at a fixed price plus an agreed amount of "interest"
which may be reflected in the repurchase price. Reverse repurchase agreements
are considered to be borrowings by the Fund. Reverse repurchase agreements
involve the risk that the market value of securities purchased by the Fund with
proceeds of the transaction may decline below the repurchase price of the
securities sold by the Fund which it is obligated to repurchase. To minimize
various risks associated with reverse repurchase agreements, the Fund will
establish and maintain with the Fund's custodian a separate account consisting
of liquid securities, of any type or maturity, in an amount at least equal to
the repurchase prices of the securities (plus any accrued interest thereon)
under such agreements. 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
except from banks temporarily for extraordinary or emergency purposes (not for
leveraging or investment) and then in an aggregate amount not in excess of 33
1/3% of the value of the Fund's total assets (including the amount borrowed)
less liabilities (not including the amount borrowed). The Fund will enter into
reverse repurchase agreements only with federally insured banks 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.

Restricted Securities. The Fund may purchase securities that are not registered
("restricted securities") under the Securities Act of 1933 ("1933 Act"),
including commercial paper issued in reliance on section 4(2) of the 1933 Act
and securities offered and sold to "qualified institutional buyers" under Rule
144A under the 1933 Act. The Fund will not invest more than 15% of its net
assets in illiquid investments. If the Trustees determine based upon a
continuing review of the trading markets for specific Section 4(2) paper or Rule
144A securities, that they are liquid, they 


                                       6
<PAGE>

will not be subject to the 15% 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. The Fund will not invest more than 5% of its total
assets in Rule 144A securities without first supplementing the prospectus and
providing additional information to shareholders.

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

Writing Covered Options. A call option on securities written by the Fund
obligates the Fund to sell specified securities to the holder of the option at a
specified price if the option is exercised at any time before the expiration
date. A put option on securities written by a 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 Funds are covered. A written call option
or put option may be covered by (i) maintaining cash or liquid securities in a
segregated account maintained by the Fund's custodian 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.


                                       7
<PAGE>

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. Put options may
also be purchased by the Fund for the purpose of affirmatively benefiting from a
decline in the price of securities which it does not own. The Fund would
ordinarily realize a gain if, during the option period, the value of the
underlying securities decreased below the exercise price sufficiently to cover
the premium and transaction costs; otherwise the Fund would realize either no
gain or a loss on the purchase of the put option. Gains and losses on the
purchase of put options may be offset by countervailing changes in the value of
the Fund's portfolio securities.

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 a domestic or foreign options exchange will exist for any
particular exchange-traded option or at any particular time. If the Fund is
unable to effect a closing purchase transaction with respect to covered options
it has written, the Fund will not be able to sell the underlying securities or
dispose of assets held in a segregated account until the options expire or are
exercised. Similarly, if the Fund is unable to effect a closing sale transaction
with respect to options it has purchased, it would have to exercise the options
in order to realize any profit and will incur transaction costs upon the
purchase or sale of underlying securities.

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

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

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

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

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

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

Hedging and Other Strategies. 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 financial instruments, securities indices or other indices, the
Fund may also enter into such futures contracts as part of its hedging strategy.
Although under some circumstances prices of securities in the Fund's 


                                       9
<PAGE>

portfolio may be more or less volatile than prices of such futures contracts,
the Adviser will attempt to estimate the extent of this volatility difference
based on historical patterns and compensate for any differential by having the
Fund enter into a greater or lesser number of futures contracts or by attempting
to achieve only a partial hedge against price changes affecting the Fund's
portfolio securities.

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

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

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

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

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

Other Considerations. The Fund will engage in futures and related options
transactions either for bona fide hedging purposes or to seek to increase total
return as permitted by the CFTC. To the extent that the Fund is using futures
and related options for hedging purposes, futures contracts will be sold to
protect against a decline in the price of securities that the Fund owns or
futures contracts will be purchased to protect the Fund against an increase in
the price of securities it intends to purchase. The Fund will determine that the
price fluctuations in the futures contracts and options on futures used for
hedging purposes are substantially related to price fluctuations in securities
held by the Fund or securities or instruments which it expects to purchase. As
evidence of its hedging intent, the Fund expects that on 75% or more of the
occasions on which 


                                       10
<PAGE>

it takes a long futures or option position (involving the purchase of futures
contracts), the Fund will have purchased, or will be in the process of
purchasing, equivalent amounts of related securities in the cash market at the
time when the futures or option position is closed out. However, in particular
cases, when it is economically advantageous for the Fund to do so, a long
futures position may be terminated or an option may expire without the
corresponding purchase of securities or other assets.

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

Transactions in futures contracts and options on futures involve brokerage
costs, require margin deposits and, in the case of contracts and options
obligating the Fund to purchase securities, require the Fund to establish with
the custodian 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. There are no futures contracts based upon
individual securities, except certain U.S. Government securities. The only
futures contracts available to hedge the Fund's portfolio are various futures on
U.S. Government securities, securities indices and foreign currencies. 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.

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 


                                       11
<PAGE>

to be advantageous. The purchase of securities on a when-issued or forward
commitment basis may also involve 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, of any type or maturity, 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.

Mortgage "Dollar Roll" Transactions. The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers pursuant to which the
Fund sells mortgage-backed securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date. The Fund will only enter into covered rolls. A "covered roll" is a
specific type of dollar roll for which there is an offsetting cash position or a
cash equivalent security position which matures on or before the forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior security and will be excluded from the calculation
of the Fund's borrowing and other senior securities. For financial reporting and
tax purposes, the Fund treats mortgage dollar rolls as two separate
transactions; one involving the purchase of a security and a separate
transaction involving a sale. The Fund does not currently intend to enter into
mortgage dollar roll transactions that are accounted for as a financing.

Asset-Backed Securities. The Fund may invest a portion of its assets in
asset-backed securities. Asset-backed securities are often subject to more rapid
repayment than their stated maturity date would indicate as a result of the
pass-through of prepayments of principal on the underlying loans. During periods
of declining interest rates, prepayment of loans underlying asset-backed
securities can be expected to accelerate. Accordingly, the Fund's ability to
maintain positions in these securities will be affected by reductions in the
principal amount of such securities resulting from prepayments, and its ability
to reinvest the returns of principal at comparable yields is subject to
generally prevailing interest rates at that time.

Credit card receivables are generally unsecured and the debtors on such
receivables are entitled to the protection of a number of state and federal
consumer credit laws, many of which give such debtors the right to set-off
certain amounts owed on the credit cards, thereby reducing the balance due.
Automobile receivables generally are secured, but by automobiles rather than
residential real property. Most issuers of automobile receivables permit the
loan services to retain possession of the underlying obligations. If the service
were to sell these obligations to another party, there is a risk that the
purchaser would acquire an interest superior to that of the holders of the
asset-backed securities. In addition, because of the large number of vehicles
involved in a typical issuance and technical requirements under state laws, the
trustee for the holders of the automobile receivables may not have a proper
security interest in the underlying automobiles. Therefore, there is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

Participation Interests. Participation interests, which may take the form of
interests in, or assignments of certain loans, are acquired from banks who have
made these loans or are members of a lending syndicate. The Fund's investments
in participation interests may be subject to its 15% limitation on investments
in illiquid securities.


                                       12
<PAGE>

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 benchmark 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.

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,
currency 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. For example, if the Fund agreed to exchange payments
in dollars for payments in a foreign currency, the swap agreement would tend to
decrease the Fund's exposure to U.S. interest rates and increase its exposure to
foreign currency and interest rates. 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.

Pay-In-Kind, Delayed and Zero Coupon Bonds. The Fund may invest in pay-in-kind,
delayed and zero coupon bonds. These are securities issued at a discount from
their face value because interest payments are typically postponed until
maturity. The amount of the discount rate varies depending on factors including
the time remaining until maturity, prevailing interest rates, the


                                       13
<PAGE>

security's liquidity and the issuer's credit quality. These securities also may
take the form of debt securities that have been stripped of their interest
payments. A portion of the discount with respect to stripped tax-exempt
securities or their coupons may be taxable. The market prices in pay-in-kind,
delayed and zero coupon bonds generally are more volatile than the market prices
of interest-bearing securities and are likely to respond to a greater degree to
changes in interest rates than interest-bearing securities having similar
maturities and credit quality. The Fund's investments in pay-in-kind, delayed
and zero coupon bonds may require the Fund to sell certain of its portfolio
securities to generate sufficient cash to satisfy certain income distribution
requirements. See "Tax Status."

The composition and weighted average maturity of the Fund's portfolio will vary
from time to time, based upon the determination of the Adviser of how best to
further the Fund's investment objective.

Lending of Securities. The Fund may lend portfolio securities to brokers,
dealers, and financial institutions if the loan is collateralized by cash or
Government Securities according to applicable regulatory requirements. The Fund
may reinvest any cash collateral in short-term securities and money market
funds. When the Fund lends portfolio securities, there is a risk that the
borrower may fail to return the securities involved in the transaction. As a
result, the Fund may incur a loss or, in the event of the borrower's bankruptcy,
the Fund may be delayed in or prevented from liquidating the collateral. It is a
fundamental policy of the Fund not to lend portfolio securities having a total
value exceeding 30% of its total assets.

Trading of Securities. The Fund may trade those Government Securities which are
not covering outstanding options positions and are not on loan to broker-dealers
if the Fund's Adviser believes that there are opportunities to exploit
differentials in prices and yields or fluctuations in interest rates, consistent
with its investment objective. Such trading may have the effect of increasing
the Fund's portfolio turnover rate. See "Portfolio Turnover".

   
Portfolio  Turnover.  If the Fund writes a number of call options and the market
prices of the underlying securities  appreciate,  or if the Fund writes a number
of put options and the market prices of the  underlying  securities  depreciate,
there may be a substantial  turnover of the  portfolio.  While the Fund will pay
commissions in connection with its options  transactions,  Government Securities
are generally traded on a "net" basis with dealers acting as principal for their
own accounts  without a stated  commission.  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 the approval of a majority of the Fund's outstanding
voting securities which, as used in the Prospectus and this Statement of
Additional Information, means the approval by the lesser of (1) the holders of
67% or more of the Fund's shares represented at a meeting if more than 50% of
the Fund's outstanding shares are present in person or by proxy at that meeting
or (2) more than 50% of the Fund's outstanding shares.

      The Fund may not:

      1. Purchases on Margin and Short Sales. Purchase securities on margin or
sell short, except that the Fund may obtain such short term credits as are
necessary for the clearance of 


                                       14
<PAGE>

securities transactions. The deposit or payment by the Fund of initial or
maintenance margin in connection with futures contracts or related options
transactions is not considered the purchase of a security on margin.

      2. Borrowing. Borrow money, except from banks temporarily for
extraordinary or emergency purposes (not for leveraging or investment) and then
in an aggregate amount not in excess of 33 1/3% of the value of the Fund's total
assets (including the amount borrowed) less liabilities (not including the
amount borrowed).

      3. Underwriting Securities. Act as an underwriter of securities of other
issuers, except to the extent that it may be deemed to act as an underwriter in
certain cases when disposing of restricted securities.

      4. Senior Securities. Issue senior securities except as appropriate to
evidence indebtedness which the Fund is permitted to incur, provided that, to
the extent applicable, (i) the purchase and sale of futures contracts or related
options, (ii) collateral arrangements with respect to futures contracts, related
options, forward foreign currency exchange contracts or other permitted
investments of the Fund as described in the Prospectus, including deposits of
initial and variation margin, and (iii) the establishment of separate classes of
shares of the Fund for providing alternative distribution methods are not
considered to be the issuance of senior securities for purposes of this
restriction.

      5. Warrants. Invest in marketable warrants to purchase common stock.
Warrants acquired in units or attached to securities are not included in this
restriction.

      6. Single Issuer Limitation/Diversification. Purchase securities of any
one issuer, except securities issued or guaranteed by the U.S. Government, its
agencies or instrumentalities, if immediately after such purchase more than 5%
of the value of the Fund's total assets would be invested in such issuer or the
Fund would own or hold more than 10% of the outstanding voting securities of
such issuer; provided, however, that up to 25% of the value of the Fund's total
assets may be invested without regard to these limitations.

      7. Real Estate. Purchase or sell real estate although the Fund may
purchase and sell securities which are secured by real estate, mortgages or
interests therein, or issued by companies which invest in real estate or
interests therein; provided, however, that the Fund will not purchase real
estate limited partnership interests.

      8. Commodities; Commodity Futures; Oil and Gas Exploration and Development
Programs. Purchase or sell commodities or commodity futures contracts or
interests in oil, gas or other mineral exploration or development programs,
except the Fund may engage in such forward foreign currency contracts and/or
purchase or sell such futures contracts and options thereon as described in the
Prospectus.

      9. Making Loans. Make loans, except that the Fund may purchase or hold
debt instruments and may enter into repurchase agreements (subject to
Restriction 12) in accordance with its investment objective and policies and
make loans of portfolio securities provided that as a result, no more than 30%
of the total assets of the Fund, taken at current value, would be so loaned.

      10. Industry Concentration. Purchase any securities which would cause more
than 25% of the market value of the Fund's total assets at the time of such
purchase to be invested in 


                                       15
<PAGE>

the securities of one or more issuers having their principal business activities
in the same industry, provided that there is no limitation with respect to
investments in obligations issued or guaranteed by the U.S. Government, its
agencies or instrumentalities.

Nonfundamental Investment Restrictions. The following restrictions are
designated as nonfundamental and may be changed by the Trustees without
shareholder approval.

      The Fund may not:

      11. Options Transactions. Write, purchase, or sell puts, calls or
combinations thereof except that the Fund may write, purchase or sell puts and
calls on securities as described in the Prospectus and this Statement of
Additional Information.

      12. Invest more than 15% of its net assets in illiquid securities.

      13. Acquisition for Control Purposes. Purchase securities of any issuer
for the purpose of exercising control or management, except in connection with a
merger, consolidation, acquisition or reorganization.

      14. Joint Trading Accounts. Participate on a joint or joint and several
basis in any trading account in securities (except for a joint account with
other funds managed by the Adviser for repurchase agreements permitted by the
Securities and Exchange Commission pursuant to an exemptive order).

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

If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage resulting from a change in values of
portfolio securities or amounts of net assets will not be considered a violation
of any of the foregoing restrictions (with the exception of Restriction 2
permitting the Fund to borrow up to 33 1/3% of the value of its total assets).

THOSE RESPONSIBLE FOR MANAGEMENT

   
The business of the Fund is managed by its Trustees 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 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 $26 billion in assets under management
in its capacity as investment adviser to the Fund and other mutual funds and
publicly traded investment companies in the John Hancock group of funds having a
combined total of over 1,4080,000 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's. Founded in 1862, the Life Company has been serving clients for over 130
years.
    

The Fund has entered into an investment management contract agreement (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 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 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 upon the following annual rates: 0.50% of the Fund's
first $500 million of average daily net assets, and 0.45% of average daily net
assets in excess of that amount.

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

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 


                                       25
<PAGE>

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 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 theAdvisory
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 reckless disregard by the Adviser of the obligations and duties under
the Advisory Agreement.
    

Under the Advisory Agreement, the Fund may use the name "John Hancock" or any
name derived from or similar to it only for so long as the Advisory Agreement or
any extension, renewal or amendment thereof remains in effect. If the Advisory
Agreement is no longer in effect, the Fund (to the extent that it lawfully can)
will cease to use such a 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 nonexclusive 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.
    

For the fiscal years ended October 31, 1995 and 1996 and for the period from
November 1,1996 to May 31, 1997, the Fund paid the Adviser fees in the amount of
$2,514,147, $2,346,755, and $1,218,973, respectively.

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 October 31, 1996, the Fund paid
the Adviser $28,344 under this agreement. For the period from November 1, 1996
to May 31, 1997, the Fund paid the Adviser $45,712.

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 their best efforts to sell
shares of each class on behalf of the Fund. Shares of the Fund are also sold by
selected broker-dealers (the "Selling Brokers") which have entered into selling
agency agreements with the 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 Class A or Class B shares, John Hancock Funds and
Selling Brokers receive compensation from a 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. John Hancock Funds may pay extra compensation to financial
services firms selling large amounts of fund shares. This compensation would be
calculated as a percentage of fund shares sold by the firm.
    

Total underwriting commissions for sales of the Fund's Class A shares for the
fiscal years ended March 31, 1996 was $379,649 and for the period from November
1, 1996 to May 31, 1997 was $162,187. Of such amounts, $41,439 and $18,811 were
retained by John Hancock Funds in 1996 and for the period from November 1, 1996
to May 31, 1997. The remainder of the underwriting commissions were reallowed to
dealers.

The Fund's Trustees adopted Distribution Plans with respect to Class A and Class
B shares (the "Plans"), pursuant to Rule 12b-1 under the Investment Company Act
of 1940. Under the Plans the Fund will pay distribution and service fees at an
aggregate annual rate of up to 0.30% and 1.00%, respectively, 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 the John Hancock Funds for their distribution expenses, including but
not limited to: (i) initial and ongoing sales compensation to Selling Brokers
and others (including affiliates of the 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 they incur 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 the Class B Plan
at any time. For the fiscal year ended May 31, 1997 an aggregate of $5,738,472
of distribution expenses or 5.53% of the average net assets of the Class B
shares of the Fund, was not reimbursed or recovered by the John Hancock Funds
through the receipt of deferred sales charges or 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 these Plans.


                                       27
<PAGE>

Pursuant to the Plans, at least quarterly, the John Hancock FundsDistributors
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
the Independent Trustees. The Plans provide that they may be terminated without
penalty, (a) by a 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 in each
case upon 60 days' written notice to the 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 the Plan. Each
Plan provides that no material amendment to the Plans will be effective unless
it is approved by a majority vote of the Trustees and the Independent Trustees
of the Fund. The holders of Class A 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 the 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 the
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 May 31, 1997, the Fund paid John Hancock Funds the
following amounts of expenses in connection with their services for the Fund:

                                  Expense Items
                                  -------------

NET ASSET VALUE

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


                                       28
<PAGE>

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

Equity securities traded on a principal exchange or NASDAQ National Market
Issues are generally valued at last sale price on the day of valuation.
Securities in the aforementioned categories for which no sales are reported and
other securities traded over-the-counter are generally valued at the mean
between the current closing bid and asked prices.

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

Any assets or liabilities expressed in terms of foreign currencies are
translated into U.S. dollars by the custodian bank based on London currency
exchange quotations as of 5:00 p.m., London time (12:00 noon, New York time) on
the date of any determination of a Fund's NAV.

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 asset 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 they
will only be issued for full shares. The Trustees reserve the right to change or
waive a 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 of the Fund, 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 Charges. Class A shares may be offered without a front-end sales
charge or CDSC to various individuals and institutions as follows:

      o Any state, county or any instrumentality, department, authority, or
      agency of these entities that is prohibited by applicable investment laws
      from paying a sales charge or commission when it purchases shares of any
      registered investment management company.*


                                       29
<PAGE>

      o A bank, trust company, credit union, savings institution or other
      depository institution, its trust departments or common trust funds if it
      is purchasing $1 million or more for non-discretionary customers or
      accounts.*

      o A Trustee/Director or officer of the Fund; a Director or officer of the
      Adviser and its affiliates or Selling Brokers; employees or sales
      representatives of any of the foregoing; retired officers, employees or
      Directors of any of the foregoing; a member of the immediate family
      (spouse, children, grandchildren, mother, father, sister, brother,
      mother-in-law, father-in-law) of any of the foregoing; or any fund,
      pension, profit sharing or other benefit plan for the individuals
      described above.

      o A broker, dealer, financial planner, consultant or registered investment
      advisor that has entered into an 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.

      o 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.

      o A member of an approved affinity group financial services plan.*

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

      o 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. See your Merrill Lynch financial consultant for further
      information.

      o Existing full service clients of the Life Company who were group annuity
      contract holders as of September 1, 1994, and participant directed defined
      contribution plans with at least 100 eligible employees at the inception
      of the Fund account, 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 transactions
involving other investment companies or personal holding companies.

* For investments made under these provisions, John Hancock Funds may make a
payment out of its own resources to the Selling Broker in an amount not to
exceed 0.25% of the amount invested.


                                       30
<PAGE>

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 then being invested but
also the 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.

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 specified 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 IRAs, SEP,
SARSEP, 401(k), 403(b) (including TSAs), SIMPLE IRA, SIMPLE 401(k), Money
Purchase Pension, Profit Sharing and Section 457 plans. Such an investment
(including accumulations and combinations) must aggregate $50,000 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 been applied (including
accumulations and combinations) had the LOI been for the amount actually
invested.
    

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


                                       31
<PAGE>

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 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.
    

Class B shares are not available to full-service defined contribution 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 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)

Proceeds from the CDSC are paid to the Distributors and are used in whole or in
part by the Distributors to defray their 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 that are subject to CDSC,
unless indicated otherwise, in the circumstance 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
      companies.

*     Redemptions due to death or disability.

*     Redemptions made under the Reinstatement Privilege, as described in
      "Sales Charge Reductions and Waivers" of the Prospectus.

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

*     Redemptions by Retirement plans participating in Merrill Lynch servicing
      programs, if the Plan has less than $3 million in assets or 500 eligible
      employees at the date the Plan Sponsor signs the Merrill Lynch
      Recordkeeping Service Agreement. See your Merrill Lynch financial
      consultant for further information.

   
For Retirement Accounts (such as IRA, SIMPLE IRA, SIMPLE 401(k), Rollover IRA,
TSA, 457, 403 (b), 401(k), Money Purchase Pension Plan, Profit-Sharing Plan and
other plans as described in the Internal Revenue Code) unless otherwise noted.
    

*     Redemptions made to effect mandatory or life expectancy distributions
      under the Internal Revenue Code.

*     Returns of excess contributions made to these plans.

*     Redemptions made to effect distributions to participants or beneficiaries
      from employer sponsored retirement under section 401(a) of the Code (such
      as 401(k), Money Purchase Pension Plan and Profit-Sharing Plan).

*     Redemptions from certain IRA and retirement plans that purchased shares
      prior to October 1, 1992 and certain IRA plans that purchased shares prior
      to May 15, 1995.

SPECIAL REDEMPTIONS

Although it would not normally do so, the Fund has the right to pay the
redemption price of shares of the Fund in whole or in part in portfolio
securities as prescribed by the Trustees. When the shareholder sells portfolio
securities received in this fashion, the shareholder will incur a brokerage
charge. Any such securities would be valued for the 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 PROGRAMS

Exchange Privilege. The Fund permits exchanges of shares of any class of the
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 changed 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.
    


                                       35
<PAGE>

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.

Monthly Automatic Accumulation Program ("MAAP"). This 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 due 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.


                                       36
<PAGE>

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 the creation of two series. 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 classes 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 the 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 requirementconditions the Internal Revenue Service
imposes with respect to the 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 Fund available for distribution to hese
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, except as set forth below.

Unless otherwise required by the Investment Company Act of 1940 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 a 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 


                                       37
<PAGE>

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 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 credit card checks. Use of 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.

TAX STATUS

Each series of the Trust including the Fund, is treated as a separate entity for
tax purposes. The Fund has qualified as a "regulated investment company" under
Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"), and
intends to continue 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 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% nondeductible 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.

   
Distributions 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. 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 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, other than those gains and losses included in computing net
capital gain, after reduction by deductible expenses.) As a result of federal
tax legislation enacted on August 5, 1997, gain recognized after May 6, 1997
from the sale of a capital asset is taxable to individual (noncorporate)
investors at different maximum federal income tax rates, depending generally
upon the tax holding period for the asset, the federal income tax bracket of the
taxpayer, and the dates the asset was acquired and/or sold. The Treasury
Department hasmay issued guidance under the Act that enables the Fund to pass
through to its shareholders the benefits of the capital gains rates enacted in
the Act. Shareholders should consult their own tax advisers on the correct
application of these new rules. 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 


                                       38
<PAGE>

exceeded, will generally give rise to capital gains. 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.

Foreign exchange gains and losses realized by the Fund in connection with
certain transactions involving foreign currency-denominated debt securities are
subject to Section 988 of the Code, which generally causes such gains and losses
to be treated as ordinary income and losses and may affect the amount, timing
and character of distributions to shareholders.

The amount of 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
those 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  may 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  Class A 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 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.  Also,  future  Treasury  Department  guidance  issued to
implement the Act may contain additional rules for determining the tax treatment
of sales of Fund shares held for various  periods,  including  the  treatment of
losses  on sales of  shares  of  shares  held for six  months  or less  that are
recharacterized as long-term capital losses, as described above.
    

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, as computed for Federal income tax purposes, 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 


                                       39
<PAGE>

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 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 a refund of, his pro rata share of the taxes paid by the Fund,
and (c) be entitled to increase the adjusted tax basis for his shares in the
Fund by the difference between his pro rata share of such excess and his pro
rata share of such taxes.

For Federal income tax purposes, the Fund is permitted to carry forward a net
capital loss in any year to offset its own net capital gains, if any, during the
eight years following the year of the loss. To the extent subsequent net capital
gains are offset by such losses, they would not result in Federal income tax
liability to the Fund, as noted above, and would not be distributed as such to
shareholders. The capital loss carryforwards for the Fund are as follows:
$48,876,888 of capital loss carryforwards which will expire May 31, 1998 --
$282,637, OctoberMay 31, 2002-- $16,549,431, May 31, 2003 -- $26,193,155, May
31, 2004 --$3,597,046 and May 31, 2005 --$2,254,619.

The Fund's dividends and distributions will not qualify for the corporate
dividends-received deduction.

A Fund is required to accrue income on any debt securities that have more than a
de minims amount of original issue discount (or debt securities acquired at a
market discount, if the Fund elects to include market discount in income
currently) prior to the receipt of the corresponding cash payments. The mark to
market rules applicable to certain options and futures contracts may also
require the Fund to recognize 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 cash, to satisfy these distribution requirements.

   
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 intangible property taxes, the
value of its assets is attributable to) certain U.S. Government obligations,
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 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 


                                       40
<PAGE>

failure to report interest or dividend income. The Fund may refuse to accept an
application that does not contain any required taxpayer identification number or
certification that the number provided is correct. If the backup withholding
provisions are applicable, any such distributions and proceeds, whether taken in
cash or reinvested in shares, will be reduced by the amounts required to be
withheld. Any amounts withheld may be credited against a shareholder's U.S.
federal income tax liability. Investors should consult their tax advisers about
the applicability of the backup withholding provisions.

The Fund may be required to account for its transactions in forward rolls or
swaps, caps, floors and collars in a manner that, under certain circumstances,
may limit the extent of its participation in such transactions. Additionally,
the Fund may be required to recognize gain, but not loss, if a swap or other
transaction is treated as a constructive sale of an appreciated financial
position in the Fund's portfolio. The Fund may have to sell portfolio securities
under disadvantageous circumstances to generate cash, or borrow cash, to satisfy
these distribution requirements.

Different tax treatment, including penalties on certain excess contributions and
deferrals, certain pre-retirement and post-retirement distributions and certain
prohibited transactions, is accorded to accounts maintained as qualified
retirement plans. Shareholders should consult their tax advisers for more
information.

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

   
Certain options and futures transactions undertaken by the Fund may cause the
Fund to recognize gains or losses from marking to market even though its
positions have not been sold or terminated and affect the character as long-term
or short-term and timing of some capital gains and losses realized by the Fund.
Additionally, the Fund may be required to recognize gain, but not loss, if an
option or other transaction 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, futures or forward 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 gains.
Certain 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, futures and forward
contracts in order 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 classes
of investors, such as tax-exempt entities, insurance companies, and financial
institutions. 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


                                       41
<PAGE>

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 ending November 30, 1997, the yield on Class A and Class B
shares of the Fund was 5.10% and 4.63%, respectively. The average total return
of Class A shares of the Fund for the 1 year, 5 years and period from January 3,
1992 (inception of the Fund) to November 30, 1997 were 1.88%, 5.73% and 5.57%,
respectively.
    

The average total return of Class B shares of the 1 year, 5 year and 10 year
periods ended November 30, 1997 were 1.06%, 5.88% and 8.077.63%, respectively
and reflects the applicable CDSC.

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:

                     Yield = 2 ( [ ( a-b/cd ) + 1 ] ^6 - 1)

Where:

      a =   dividends and interest earned during the period.
      b =   net expenses accrued during the period.
      c =   the average daily number of shares of the Fund 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
            (NAVE where applicable).

The Fund's 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:

                             T = ((ERV/P)^(1/n)) - 1

Where:

      P =   a hypothetical initial investment of $1,000.
      T =   average annual total return
      n =   number of years


                                       42
<PAGE>

      ERV=  ending redeemable value of a hypothetical $1,000 investment made at
            designated periods or fraction thereof.

   
Because each class 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, respectively. This
calculation assumes that all dividends and distributions are reinvested at net
asset value on the reinvestment dates during the period. The "distribution rate"
is determined by annualizing the result of dividing the declared dividends of
the Fund during the period stated by the maximum offering price or net asset
value at the end of the period. Excluding the Fund's sales charge from the
distribution rate produces a higher rate.
    

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

From time to time, in reports and promotional literature, the Fund's yield and
total return and/or yield 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. Ibbotson and Associates, CDA Weisenberger and F.C. Towers are also used
for comparison purposes, as well a 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, may also be
utilized. The Fund's promotional and sales literature may make reference to the
Fund's "beta." Beta is a reflection of the market-related risk of the Fund by
showing how responsive the Fund is to the market.

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

BROKERAGE ALLOCATION

Decisions concerning the purchase and sale of portfolio securities and the
allocation of brokerage commissions are made by the Adviser pursuant to
recommendations made by an investment committee of the Adviser, which consists
of officers and directors of the Adviser and affiliates and Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner which, in the opinion of the Adviser, will offer the best
price and market for the execution of each such transaction. Purchases from
underwriters of portfolio securities 


                                       43
<PAGE>

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.

In the U.S. and in some other countries, debt securities are traded principally
in the over-the-counter market on a net basis through dealers acting for their
own account and not as brokers. Ion other countries, both debt and equity
securities are traded on exchanges at fixed commission rates. Commissions on
foreign transactions are generally higher than the negotiated commission rates
available in the U.S. There is generally less government supervision and
regulation of foreign stock exchanges and broker-dealers than in the U.S.

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, 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 Fund'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 October 31, 1996 and
1995 and for the period from November 1, 1996 to May 31, 1997, the Fund paid
negotiated brokerage commissions of $169,518, $107,825, and $ 97,937,
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. For the period ended OctoberNovember 1, 1996 to May
31, 1997, the Fund did not pay commissions as compensation to any brokers for
research services such as industry, economic and company reviews and evaluations
of securities.

The Adviser's indirect parent, the Life Company, is the indirect sole
shareholder of John Hancock Distributors, Inc. a broker-dealer (" Distributors"
or Affiliated Broker"). Pursuant to procedures determined by the Trustees and
consistent with the above policy of obtaining best net 


                                       44
<PAGE>

results, the Fund may execute portfolio transactions with or through Affiliated
Brokers. For the period ended October 31, 1995 and 1996 and for the period from
November 1, 1996 to May 1, 1997, the Fund did not execute any portfolio
transactions with the Affiliated Broker.

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 as the Fund. When these clients buy or sell the same securities
at substantially the same time, the Adviser may average the transactions 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 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.

                                   APPENDIX A

                          DESCRIPTION OF BOND RATINGS*

Moody's Bond Ratings

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

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

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

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

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

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

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

- ----------
*As described by the rating companies themselves.


                                       A-1
<PAGE>

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

Standard & Poor's Bond Ratings

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

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

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

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

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

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

                            COMMERCIAL PAPER RATINGS

Moody's Commercial Paper Ratings

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

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

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

Standard & Poor's Commercial Paper Ratings

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

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

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

</TABLE>

Item 27. Indemnification

     (a)  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.

     (b) 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 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
liability or expense  incurred in  connection  with any matter  settled  without
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
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."

                                      C-2
<PAGE>

"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 28. 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 29. Principal Underwriters

serves as principal  underwriter  or distributor of shares for John Hancock Cash
Reserve,  Inc.,  John Hancock Bond Trust,  John Hancock Current  Interest,  John
