OVERVIEW
- --------------------------------------------------------------------------------

GOAL OF THE INCOME FUNDS

John Hancock income funds seek current income, but not at the expense of total
return. Some of the funds also invest for stability of principal. Each fund
employs its own strategy and has 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

John Hancock income funds may be appropriate for investors who:

- -  are seeking a regular stream of income

- -  are seeking higher potential returns than money market funds and are willing
   to accept moderate risk of volatility

- -  want to diversify their portfolios

- -  are seeking a mutual fund for the income portion of an asset allocation 
   portfolio

- -  are in or nearing retirement

Income funds may NOT be appropriate if you:

- -  are investing for maximum return over a long time horizon

- -  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 $19 billion in assets.

- --------------------------------------------------------------------------------
GOAL AND STRATEGY

[A GRAPHIC IMAGE OF A BULLSEYE WITH AN ARROW IN THE MIDDLE OF IT]
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

[A GRAPHIC IMAGE OF A BLACK FOLDER THAT CONTAINS A COUPLE SHEETS OF PAPER]
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 and Fannie Maes, and
repurchase agreements and forward commitments involving these securities.

For liquidity and flexibility, the fund may place up to 20% of net 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 other investments, including asset-backed securities, foreign
government securities 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 categories,
respectively, or if unrated, be of comparable quality. Up to 10% of assets may
be invested in bonds rated as low as B.

RISK FACTORS

[A GRAPHIC IMAGE OF A LINE CHART WITH A SINGLE LINE THAT DEPICTS SOME PEAKS AND
VALLEYS]
As with most income funds, the value of your investment in the fund 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
29. 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

[A GRAPHIC IMAGE OF A GENERIC PERSON]
Barry H. Evans, leader of the fund's portfolio management team since 1995, is a
senior vice president of the adviser. He joined John Hancock Funds in 1986.

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) May include carry-over of reimbursable costs from previous year(s). Amounts
    shown are the fund's current annual maximums for 12b-1 fees. 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

[A GRAPHIC IMAGE OF A BULLSEYE WITH AN ARROW IN THE MIDDLE OF IT]
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

[A GRAPHIC IMAGE OF A BLACK FOLDER THAT CONTAINS A COUPLE SHEETS OF PAPER]
Under normal circumstances, the fund invests at least 65% of assets in
securities rated lower than BBB/Baa, or if unrated, of equivalent quality. No
more than 10% of assets may be invested in securities rated as low as 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 securities include, but are not limited to, domestic and foreign
corporate bonds, debentures, notes, convertible securities, preferred stocks,
municipal obligations and government obligations.

For liquidity and flexibility, the fund may place up to 35% of net 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 other investments and may engage in other investment
practices.

RISK FACTORS

[A GRAPHIC IMAGE OF A LINE CHART WITH A SINGLE LINE THAT DEPICTS SOME PEAKS AND
VALLEYS]
Investors should expect greater fluctuations in share price, yield and total
return compared to 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 repay interest or principal is uncertain. Compared to 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 29.

PORTFOLIO MANAGEMENT

[A GRAPHIC IMAGE OF A GENERIC PERSON]
Arthur N. Calavritinos, leader of the fund's portfolio management team since
1995, is a second vice president of the adviser. He joined John Hancock Funds in
1988.

GOAL AND STRATEGY

[A GRAPHIC IMAGE OF A BULLSEYE WITH AN ARROW IN THE MIDDLE OF IT]
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 is typically between three
and ten years.

PORTFOLIO SECURITIES

[A GRAPHIC IMAGE OF A BLACK FOLDER THAT CONTAINS A COUPLE SHEETS OF PAPER]
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. The fund may
invest up to 5% of assets in U.S. Government securities denominated in a foreign
currency.

For liquidity and flexibility, the fund may place up to 35% of net 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 other investments, including corporate bonds and leveraged
investments, and may engage in other investment practices.

RISK FACTORS

[A GRAPHIC IMAGE OF A LINE CHART WITH A SINGLE LINE THAT DEPICTS SOME PEAKS AND
VALLEYS]
As with most income funds, the value of your investment in the fund 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
29. Other factors may affect the market price and yield of the fund's securities
as well, 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

[A GRAPHIC IMAGE OF A GENERIC PERSON] Roger Hamilton, leader of the fund's
portfolio management team since 1992, is a second vice president of the adviser.
He has worked in the investment business since 1980.

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

(3) Reflects the investment adviser's temporary agreement to limit expenses
    (except for 12b-1 and other class-specific expenses). Without this
    limitation, management fees would have been 0.40% for each class, other
    expenses would have been 0.72% for each class, and total fund operating
    expenses would have been 1.37% for Class A and 2.02% for Class B.
(4) May include carry-over of reimbursable costs from previous year(s). Amounts
    shown are the fund's current annual maximums for 12b-1 fees. Class B fee may
    be increased from 0.90% to 1.00% after December 31, 1996. 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

[A GRAPHIC IMAGE OF A BULLSEYE WITH AN ARROW IN THE MIDDLE OF IT]
The fund seeks to provide current income and security of principal. To pursue
this goal, the fund invests primarily in U.S. Government and agency securities,
as described below. The fund's securities may be of any maturity, although a
substantial portion will typically have maturities of ten years or less.

PORTFOLIO SECURITIES

[A GRAPHIC IMAGE OF A BLACK FOLDER THAT CONTAINS A COUPLE SHEETS OF PAPER]
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.

For liquidity and flexibility, the fund may place up to 20% of net 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 other investments and may engage in other investment
practices.

RISK FACTORS

[A GRAPHIC IMAGE OF A LINE CHART WITH A SINGLE LINE THAT DEPICTS SOME PEAKS AND
VALLEYS]
In seeking to maintain a relatively stable share price, the fund may sacrifice
opportunities for higher yields. At the same time, its share price will
fluctuate to some extent with changes 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 29.

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

[A GRAPHIC IMAGE OF A GENERIC PERSON]
Barry H. Evans, leader of the fund's portfolio management team since 1995, is a
senior vice president of the adviser. He joined John Hancock Funds in 1986.

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) May include carry-over of reimbursable costs from previous year(s). Amounts
    shown are the fund's current annual maximums for 12b-1 fees. Because of the
    12b-1 fee, long-term shareholders may indirectly pay more than the
    equivalent of the maximum permitted front-end sales charge.

                                   TICKER SYMBOL  CLASS A: JHNBX  CLASS B: JHBBX
- --------------------------------------------------------------------------------
GOAL AND STRATEGY

[A GRAPHIC IMAGE OF A BULLSEYE WITH AN ARROW IN THE MIDDLE OF IT]
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. The fund does not concentrate its investments in any
particular industry.

PORTFOLIO SECURITIES

[A GRAPHIC IMAGE OF A BLACK FOLDER THAT CONTAINS A COUPLE SHEETS OF PAPER]
Under normal circumstances, the fund invests at least 65% of assets in bonds or
debentures. Typically, at least three-quarters of these debt securities
(excluding commercial paper) will be: o securities rated among the four highest
Moody's or S&P rating categories at the time of purchase o if unrated, the
equivalent of the above o bank securities o U.S. Government and agency
securities

For liquidity and flexibility, the fund may place up to 35% of its net 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 other investments, including dollar-denominated foreign
securities, asset-backed securities, junk bonds and leveraged investments, and
may engage in other investment practices.

RISK FACTORS

[A GRAPHIC IMAGE OF A LINE CHART WITH A SINGLE LINE THAT DEPICTS SOME PEAKS AND
VALLEYS]
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 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 29. The longer the fund's average weighted maturity, the more it is likely
to be affected by a change in interest rates. Other factors that can affect
performance are economic news, investor demand and world political and economic
conditions. Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT

[A GRAPHIC IMAGE OF A GENERIC PERSON]
James K. Ho, leader of the fund's portfolio management team since 1988, is an
executive vice president and the senior fixed-income officer of the adviser. He
joined John Hancock Funds in 1985.

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) May include carry-over of reimbursable costs from previous year(s). Amounts
    shown are the fund's current annual maximums for 12b-1 fees. 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

[A GRAPHIC IMAGE OF A BULLSEYE WITH AN ARROW IN THE MIDDLE OF IT]
The fund seeks to provide as high 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

[A GRAPHIC IMAGE OF A BLACK FOLDER THAT CONTAINS A COUPLE SHEETS OF PAPER]
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 net 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 other investments, including leveraged investments, and may
engage in other investment practices.

RISK FACTORS

[A GRAPHIC IMAGE OF A LINE CHART WITH A SINGLE LINE THAT DEPICTS SOME PEAKS AND
VALLEYS]
As with most income investments, the value of your investment in the fund 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
29. 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

[A GRAPHIC IMAGE OF A GENERIC PERSON]
Barry H. Evans, leader of the fund's portfolio management team since 1995, is a
senior vice president of the adviser. He joined John Hancock Funds in 1986.

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) May include carry-over of reimbursable costs from previous year(s). Amounts
    shown are the fund's current annual maximums for 12b-1 fees. Because of the
    12b-1 fee, long-term shareholders may indirectly pay more than the
    equivalent of the maximum permitted front-end sales charge.

STRATEGIC INCOME FUND

REGISTRANT NAME: JOHN HANCOCK STRATEGIC SERIES 
                                   TICKER SYMBOL  CLASS A: JHFIX  CLASS B: STIBX
- --------------------------------------------------------------------------------
GOAL AND STRATEGY

[A GRAPHIC IMAGE OF A BULLSEYE WITH AN ARROW IN THE MIDDLE OF IT]
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, i.e
lower-rated, higher-yielding debt securities

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 reserves the right
to invest up to 100% of assets in any sector.

PORTFOLIO SECURITIES

[A GRAPHIC IMAGE OF A BLACK FOLDER THAT CONTAINS A COUPLE SHEETS OF PAPER]
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 its 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
other investments, including leveraged investments, and may engage in other
investment practices.

RISK FACTORS

[A GRAPHIC IMAGE OF A LINE CHART WITH A SINGLE LINE THAT DEPICTS SOME PEAKS AND
VALLEYS]
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. A fall in interest
rates can result in net lower yields from assets invested in mortgage-backed
securities. The longer the fund's average weighted maturity, the more it is
likely to be affected by a change in interest rates. Junk bond markets may react
strongly to adverse news about an issuer or the economy, or to the perception or
expectation of adverse news. To the extent that the fund invests in these types
of securities, it assumes the various risks associated with each one. In
addition, there is the risk that the asset weightings chosen by the fund
managers may result in share price declines or lost opportunities for gains.
Before you invest, please read "More about risk" starting on page 29.

PORTFOLIO MANAGEMENT

[A GRAPHIC IMAGE OF A GENERIC PERSON]
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 worked in the investment business since 1973.

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) May include carry-over of reimbursable costs from previous year(s). Amounts
    shown are the fund's current annual maximums for 12b-1 fees. 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.
Each class has its own cost structure, allowing you to choose the one that best
meets your requirements. Your financial representative can help you decide.

CLASS A

- -    Front-end sales charges, as described below. There are several ways to
     reduce these charges, also described below.

- -    Lower annual expenses than Class B shares.

CLASS B

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

- -    Higher annual expenses than Class A shares.

- -    A deferred sales charge, as described below.

- -    Automatic conversion to Class A shares after either five years (Group 1) or
     eight years (Group 2) (see below), thus reducing future annual expenses.

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

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:

- ---------------------------------------------------------
</TABLE>

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.

SALES CHARGE REDUCTIONS AND WAIVERS

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

- -    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.

- -    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.

- -    Combination Privilege -- lets you combine Class A shares of multiple funds
     for purposes of calculating the sales charge.

To utilize: complete the appropriate section on your application, or contact
your financial representative or Investor Services to add these options to an
existing account (see the back cover of this prospectus).

GROUP INVESTMENT PROGRAM Allows established groups of four or more investors to
invest as a group. Each has an individual account, but for sales charge
purposes, their investments are lumped together, making the investors
potentially eligible for reduced sales charges. There is no charge, no
obligation to invest (although initial aggregate investments must be at least
$250), and you may terminate the program at any time.

To utilize: contact your financial representative or Investor Services to find
out how to qualify.

CDSC WAIVERS In general, the CDSC for either share class may be waived on shares
you sell for the following reasons: 

- -    to make payments through certain Systematic Withdrawal Plans

- -    to make certain distributions from a retirement plan

- -    because of shareholder death or disability

To utilize: contact your financial representative or Investor Services, or
consult the SAI (see the back cover of this prospectus).

REINSTATEMENT PRIVILEGE If you sell shares in a John Hancock fund, you may
invest some or all of the proceeds in the same share class of any John Hancock
fund within 120 days without a sales charge. 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 Investor Services.

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' 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, as described earlier.

EXECUTION OF REQUESTS Each fund is open on those days when the New York Stock
Exchange is open, typically Monday - Friday. Buy and sell requests are executed
at the next NAV to be calculated after your request is accepted by Investor
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, Investor Services will take
measures to verify the identity of the caller, such as asking for name, account
number, Social Security or taxpayer ID number and other relevant information.
If these measures are not taken, Investor Services is 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 your John Hancock fund for shares of the
same class in any other John Hancock fund, generally without paying any
additional sales charges. Class B shares will continue to age from the original
date and will retain the same CDSC rate as they had before the exchange, except
that the rate will change to that of the new fund if the new fund's 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 change or cancel its exchange
privilege at any time, upon 60 days' notice to its shareholders. A fund may also
refuse any exchange order.

Merrill Lynch customers may exchange between Summit Cash Reserve accounts and
Class B shares of any John Hancock fund. When selling Class B shares, CDSC
calculations will be based only on the time their assets were invested in a John
Hancock fund.

CERTIFICATED SHARES Most shares are electronically recorded. If you wish to have
certificates for your shares, please write to Investor Services. Certificated
shares can only be sold by returning the certificates to Investor 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 calendar days after
the purchase.

FOREIGN CURRENCIES Purchases must be made in U.S. dollars. Purchases in foreign
currencies must be converted, which may result in a fee and delayed execution.

ELIGIBILITY BY STATE You may only invest in, or exchange into, fund shares that
are legally available in your state.

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

ACCOUNT STATEMENTS In general, you will receive account statements as follows: 

- -        after every transaction (except a dividend reinvestment) that affects
         your account balance

- -        after any changes of name or address of the registered owner(s)

- -        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.

24 YOUR ACCOUNT

<PAGE>
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.

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.

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, your fund's transfer agent 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) 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: 

- -        Complete the appropriate parts of your Account Privileges Application.

- -        If you are using MAAP to open an account, make out a check ($25
         minimum) for your first investment amount payable to "John Hancock
         Investor Services Corporation." Deliver your check and application to
         your financial representative or Investor Services.

SYSTEMATIC WITHDRAWAL PLAN May be used for routine bill payment or periodic
withdrawals from your account. To establish: 

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

- -        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).

- -        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.

- -        Determine the schedule: monthly, quarterly, semi-annually, annually, or
         in certain selected months.

- -        Fill out the relevant part of the Account Privileges Application. To
         add a Systematic Withdrawal Plan to an existing account, contact your
         financial representative or Investor Services.

RETIREMENT PLANS John Hancock Funds offers a range of qualified retirement
plans, including IRAs, SEPs, SARSEPs, TSAs, 401(k) plans, 403(b) plans and other
pension and profit-sharing plans. Using these plans, you can invest in any John
Hancock fund with a low minimum investment of $250 or, for some group plans, no

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 or a board of directors, an
independent body which 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 that 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 for 1996 is estimated to be
0.01875% 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 that 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.

ADVERTISEMENT OF PERFORMANCE The funds may include figures for yield (where
appropriate) and total return in advertisements and other sales materials, as
follows:

DEFINITIONS OF PERFORMANCE MEASURES                                   

MEASURE             DEFINITION

Cumulative          Overall dollar or percentage change of a hypothetical       
total return        investment over the stated time period.                     
                                                                                
Average             Cumulative total return divided by the number of years in   
annual total        the period. The result is an average and is not the same as 
return              the actual year-to-year results.                            
                                                                                
Yield               A measure of income, calculated by taking the net investment
                    income per share for a 30-day period, dividing it by the    
                    offering price per share on the last day of the period (if  
                    there is more than one offering price, the highest price is 
                    used) 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.       

All performance figures assume that dividends are reinvested, and show the
effect of all applicable sales charges. Class A performance figures generally
are calculated using the maximum sales charge. Because each share class has its
own sales charge and fee structures, the classes have different performance
results.

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.

- --------------------------------------------------------------------------------
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 fund in 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' respective boards. 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.

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.

From time to time, as an additional incentive to these firms, John Hancock Funds
may increase the reallowance on Class A shares to as much as the entire
front-end sales charge.

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. Firms affiliated
with John Hancock, which include Tucker Anthony, Sutro & Company and John
Hancock Distributors, may receive an additional fee of up to 0.05% a year of
their total eligible net assets.

                                                                 FUND DETAILS 27

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  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
higher risk securities and investment practices, along with the risks associated
with them. The funds follow certain policies that may reduce these risks.

As with any bond 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.

- --------------------------------------------------------------------------------
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.

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

- -    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 securities and practices.

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.

OPPORTUNITY RISK The risk of missing out on an investment opportunity because
the assets necessary to take advantage of it are tied up in other 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, 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.

                                                                 FUND DETAILS 29

ORGANIZATION OF THE FUND


     John Hancock  Sovereign  Bond Fund (the "Fund") is a  diversified  open-end
management investment company organized as a Massachusetts  business trust under
the laws of The Commonwealth of Massachusetts. The Fund was organized in 1984 by
John Hancock  Advisers,  Inc.  (the  "Adviser") as the successor to John Hancock
Bond Fund, Inc., a Maryland  corporation  organized in 1973 by the 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  Fund's  investment  objective  is to  generate a high level of current
income,  consistent  with  prudent  investment  risk,  for  distribution  to its
shareholders through investment in a diversified  portfolio of freely marketable
debt  securities.   The  Fund's  investments  will  be  subject  to  the  market
fluctuations  and risks inherent in all  securities.  There is no assurance that
the Fund will achieve its investment  objective.  See "Goal and Strategy" in the
Fund's Prospectus.
    
     The Fund will invest  primarily in debt securities  within the four highest
investment  ratings and unrated  securities  considered  by the Adviser to be of
comparable  investment  quality.  The Fund will,  when  feasible,  purchase debt
securities which are non-callable.

     The Fund may purchase  corporate debt securities bearing fixed or fixed and
contingent  interest as well as those which carry certain equity features,  such
as conversion or exchange rights or warrants for the acquisition of stock of the
same or a  different  issuer,  or  participations  based on  revenues,  sales or
profits.  The Fund will not exercise any such  conversion,  exchange or purchase
rights if, at the time, the value of all equity  interests so owned would exceed
10% of the Fund's total assets taken at market value.

     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. Similarly,  when such yields increase, the market value of a
portfolio already invested 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,  during  periods of high interest  rates,
because  of  their  lower  acquisition  cost  tend  to  sell  on a  yield  basis
approximating current interest rates.

     The Fund  intends to use  short-term  trading of  securities  as a means of
managing  its  portfolio  to achieve  its  investment  objective.  The Fund,  in

                                       2

<PAGE>

reaching a decision  to sell one  security  and  purchase  another  security  at
approximately  the same  time,  will  take into  account  a number  of  factors,
including the quality  ratings,  interest rates,  yields,  maturity dates,  call
prices,  and  refunding  and sinking fund  provisions  of the  securities  under
consideration,  as  well  as  historical  yield  spreads  and  current  economic
information.  The success of short-term  trading will depend upon the ability of
the Fund to  evaluate  particular  securities,  to  anticipate  relevant  market
factors,  including  trends of interest rates and earnings and  variations  from
such trends,  to obtain relevant  information,  to evaluate it promptly,  and to
take  advantage of its  evaluations  by completing  transactions  on a favorable
basis. It is expected that the expenses  involved in short-term  trading,  which
would not be incurred by an investment company which does not use this portfolio
technique,  will be significantly less than the profits and other benefits which
will accrue to shareholders.
   
     The portfolio  turnover rate will depend on a number of factors,  including
the fact that the Fund intends to continue to qualify as a regulated  investment
company  under the  Internal  Revenue  Code of 1986,  as amended  (the  "Code").
Accordingly,  the Fund intends to limit its short-term trading so that less than
30% of the Fund's  gross  annual  income  (including  all  dividend and interest
income and gross realized capital gains, both short and long-term, without being
offset for realized capital losses) will be derived from gross realized gains on
the sale or other  disposition  of  securities  held for less than three months.
This  limitation,  which must be met by all mutual funds in order to obtain such
Federal tax  treatment,  at certain  times may  prevent the Fund from  realizing
capital gains on some securities held for less than three months.
    
CERTAIN INVESTMENT PRACTICES
   
     Securities  of Domestic  and Foreign  Issuers.  The Fund may invest in U.S.
dollar-denominated  securities  of foreign and United  States  issuers  that are
issued in or outside of the United States.  Foreign companies may not be subject
to accounting standards and government supervision comparable to U.S. companies,
and there is often less publicly  available  information about their operations.
Foreign  markets  generally  provide less liquidity than U.S.  markets (and thus
potentially  greater price  volatility) and typically  provide fewer  regulatory
protections for investors.  Foreign securities can also be affected by political
or financial instability abroad. It is anticipated that under normal conditions,
the Fund will not invest more than 25% of its total assets in foreign securities
(excluding U.S. dollar-denominated Canadian securities).
    
   
     Mortgage-backed  and  Derivative  Securities.   Mortgage-backed  securities
represent participation interests in pools of adjustable and fixed rate mortgage
loans  which  are  guaranteed  by  agencies  or  instrumentalities  of the  U.S.
government.  Unlike  conventional debt obligations,  mortgage-backed  securities
provide  monthly  payments  derived  from the  monthly  interest  and  principal
payments  (including any  prepayments)  made by the individual  borrowers on the
pooled mortgage loans. The mortgage loans underlying  mortgage-backed securities
are generally subject to a greater rate of principal  prepayments in a declining
interest rate  environment  and to a lesser rate of principal  prepayments in an

                                       3

<PAGE>

increasing  interest rate  environment.  Under certain  interest and  prepayment
scenarios,  the Fund may fail to recover  the full amount of its  investment  in
mortgage-backed  securities  notwithstanding any direct or indirect governmental
or agency  guarantee.  Since faster than  expected  prepayments  must usually be
invested  in lower  yielding  securities,  mortgage-backed  securities  are less
effective than conventional  bonds in "locking in" a specified interest rate. In
a rising interest rate environment,  a declining  prepayment rate may 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.
    
   
     The  Fund's   investments   in   mortgage-backed   securities  may  include
conventional  mortgage  passthrough  securities and certain  classes of multiple
class collateralized  mortgage obligations ("CMOs"). In order to reduce the risk
of prepayment for investors,  CMOs are issued in multiple  classes,  each having
different  maturities,  interest  rates,  payment  schedules and  allocations of
principal  and  interest on the  underlying  mortgages.  Senior CMO classes will
typically have priority over residual CMO classes as to the receipt of principal
and/or interest payments on the underlying  mortgages.  The CMO classes in which
the Fund may invest  include but are not limited to sequential  and parallel pay
CMOs, including planned amortization class ("PAC") and target amortization class
("TAC") securities.
    
   
     Different  types of  mortgage-backed  securities  are subject to  different
combinations of prepayment,  extension, interest rate and/or other market risks.
Conventional mortgage passthrough 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."
    
   
     Structured  Securities.  The Fund may invest in structured notes,  bonds or
debentures,  the value of the  principal  of and/or  interest  on which is to be
determined by reference to changes in the value of specific currencies, interest
rates,  commodities,  indices or other financial indicators (the "Reference") or
the  relative  change  in two or  more  References.  The  interest  rate  or the
principal  amount  payable  upon  maturity or  redemption  may be  increased  or
decreased depending upon changes in the applicable  Reference.  The terms of the
structured  securities may provide that in certain circumstances no principal is
due at maturity and, therefore, may result in the loss of the Fund's investment.
Structured   securities  may  be  positively  or  negatively  indexed,  so  that
appreciation  of the  Reference  may  produce an  increase  or  decrease  in the
interest rate or value of the security at maturity.  In addition,  the change in
interest  rate or the value of the security at maturity may be a multiple of the
change in the value of the Reference. Consequently, structured securities entail
a greater degree of market risk than other types of debt obligations. Structured
securities  may  also be more  volatile,  less  liquid  and  more  difficult  to
accurately price than less complex fixed income investments.

     Financial Futures Contracts. The Fund may hedge its portfolio by selling or
purchasing  financial  futures  contracts  as an offset  against  the effects of
changes in interest rates or in security values. Although other techniques could
be used to reduce the Fund's  exposure to interest rate  fluctuations,  the Fund
may be able to hedge its exposure more  effectively  and perhaps at a lower cost
by using financial futures contracts.  The Fund may enter into financial futures
contracts  for  hedging and  speculative  purposes  to the extent  permitted  by
regulations of the Commodity Futures Trading Commission ("CFTC").

     Financial  futures  contracts  have been  designed by boards of trade which
have been  designated  "contract  markets" by the CFTC.  Futures  contracts  are
traded on these markets in a manner that is similar to the way a stock is traded
on a stock exchange.  The boards of trade, through their clearing  corporations,
guarantee that the contracts  will be performed.  Currently,  financial  futures
contracts are based on interest rate instruments such as long-term U.S. Treasury
bonds, U.S. Treasury notes,  Government National Mortgage  Association  ("GNMA")
modified  pass-through  mortgage-backed  securities,  three-month U.S.  Treasury
bills,  90-day  commercial  paper,  bank  certificates of deposit and Eurodollar
certificates  of  deposit.  It is  expected  that  if  other  financial  futures
contracts are developed and traded the Fund may engage in  transactions  in such
contracts.
   
     Although some  financial  futures  contracts by their terms call for actual
delivery or acceptance of financial instruments, in most cases the contracts are
closed  out prior to  delivery  by  offsetting  purchases  or sales of  matching
financial  futures  contracts (same exchange,  underlying  security and delivery
month).  Other  financial  futures  contracts,  such  as  futures  contracts  on
securities indices, by their terms call for cash settlements.  If the offsetting
purchase price is less than the Fund's original sale price,  the Fund realizes a
gain, or if it is more, the Fund realizes a loss. Conversely,  if the offsetting
sale price is more than the Fund's original  purchase price, the Fund realizes a
gain, or if it is less,  the Fund realizes a loss.  The  transaction  costs must
also be  included  in these  calculations.  The Fund  will pay a  commission  in
connection with each purchase or sale of financial futures contracts,  including
a closing transaction. For a discussion of the Federal income tax considerations
of transactions in financial  futures  contracts,  see the information under the
caption "Tax Status" below.
    
     At the  time the Fund  enters  into a  financial  futures  contract,  it is
required  to  deposit  with its  custodian  a  specified  amount of cash or U.S.
Government  securities,  known as "initial  margin," ranging upward from 1.1% of
the value of the financial  futures  contract being traded.  The margin required
for a  financial  futures  contract  is set by the board of trade or exchange on
which  the  contract  is  traded  and may be  modified  during  the  term of the
contract.  The  initial  margin is in the nature of a  performance  bond or good
faith deposit on the financial  futures  contract  which is returned to the Fund
upon termination of the contract, assuming all contractual obligations have been
satisfied.  The Fund  expects  to earn  interest  income on its  initial  margin
deposits.  Each day, the futures  contract is valued at the official  settlement

                                       5

<PAGE>

price  of the  board  of trade or  exchange  on which it is  traded.  Subsequent
payments,  known as  "variation  margin,"  to and from the  broker are made on a
daily basis as the market price of the financial  futures  contract  fluctuates.
This process is known as "mark to market." Variation margin does not represent a
borrowing or lending by the Fund but is instead  settlement between the Fund and
the  broker of the  amount  one would  owe the  other if the  financial  futures
contract expired. In computing net asset value, the Fund will mark to market its
open financial futures positions.

     Successful hedging depends on a strong  correlation  between the market for
the underlying  securities and the futures contract market for those securities.
There are several factors that may prevent this  correlation  from being perfect
and even a correct  forecast of general interest rate trends may not result in a
successful hedging  transaction.  There are significant  differences between the
securities  and futures  markets  which could  create an  imperfect  correlation
between the markets and which  could  affect the success of a given  hedge.  The
degree of  imperfection  will be affected by  variations in  speculative  market
demand for financial futures and debt securities, including technical influences
in futures trading.  Differences between the financial  instruments being hedged
and  the  instruments   underlying  the  standard  financial  futures  contracts
available for trading will be affected by interest rate levels,  maturities  and
creditworthiness  of issuers.  The degree of imperfection may be increased where
the  underlying  debt  securities are  lower-rated  and,  therefore,  subject to
greater fluctuation in price than higher-rated securities.

     A decision as to whether,  when and how to hedge  involves  the exercise of
skill and judgment,  and even a well-conceived hedge may be unsuccessful to some
degree because of market behavior or unexpected  interest rate trends.  The Fund
will bear the risk that the price of the  securities  being hedged will not move
in  complete  correlation  with the  price of the  futures  contracts  used as a
hedging  instrument.  Although  the Adviser  believes  that the use of financial
futures contracts will benefit the Fund, an incorrect prediction could result in
a loss on both the hedged  securities  in the Fund's  portfolio  and the hedging
vehicle so that the Fund's  return  might have been  better had hedging not been
attempted.  However,  in the absence of the ability to hedge,  the Adviser might
have taken portfolio  actions in anticipation of the same market  movements with
similar investment results but,  presumably,  at greater  transaction costs. The
low margin deposits required for futures  transactions  permit an extremely high
degree of leverage. A relatively small movement in a futures contract may result
in losses or gains in excess of the amount invested.

     Futures exchanges may limit the amount of fluctuation  permitted in certain
futures contract prices during a single trading day. The daily limit establishes
the maximum  amount the price of a futures  contract  may vary either up or down
from the previous  day's  settlement  price,  at the end of the current  trading
session.  Once the daily limit has been reached in a futures contract subject to
the limit,  no more trades may be made on that day at a price beyond that limit.
The daily limit  governs only price  movements  during a particular  trading day
and,  therefore,  does not limit potential  losses because the limit may work to

                                       6

<PAGE>

prevent the liquidation of unfavorable  positions.  For example,  futures prices
have occasionally moved to the daily limit for several  consecutive trading days
with little or no trading,  thereby  preventing prompt  liquidation of positions
and subjecting some holders of futures contracts to substantial losses.

     Finally,  although the Fund engages in financial futures  transactions only
on boards of trade or exchanges where there appears to be an adequate  secondary
market,  there is no assurance  that a liquid market will exist for a particular
futures  contract  at any given time.  The  liquidity  of the market  depends on
participants closing out contracts rather than making or taking delivery. In the
event  participants  decide to make or take  delivery,  liquidity  in the market
could be reduced. In addition,  the Fund could be prevented from executing a buy
or sell order at a specified  price or closing  out a position  due to limits on
open  positions or daily price  fluctuation  limits  imposed by the exchanges or
boards of trade. If the Fund cannot close out a position, it will be required to
continue to meet margin requirements until the position is closed.

     Options on  Financial  Futures  Contracts.  The Fund may purchase and write
call and put  options on  financial  futures  contracts.  An option on a futures
contract  gives the  purchaser  the right,  in return for the premium  paid,  to
assume a position in a futures  contract at a  specified  exercise  price at any
time during the period of the option.  Upon  exercise,  the writer of the option
delivers  the futures  contract to the holder at the  exercise  price.  The Fund
would be required to deposit with its  custodian  initial and  variation  margin
with respect to put and call options on futures contracts written by it. Options
on futures contracts involve risks similar to the risks relating to transactions
in financial futures contracts. Also, an option purchased by the Fund may expire
worthless, in which case the Fund would lose the premium it paid for the option.
   
     Other Considerations. The Fund will engage in futures transactions for bona
fide  hedging  or  speculative   purposes  to  the  extent   permitted  by  CFTC
regulations.  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 which it expects
to purchase.  Except as stated below,  the Fund's futures  transactions  will be
entered into for traditional hedging purposes -- i.e., futures contracts will be
sold to protect  against  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  the Fund intends to  purchase.  As evidence of this
hedging  intent,  the Fund expects that on 75% or more of the occasions on which
it takes a long futures or option  position  (involving  the purchase of futures
contracts),  the  Fund  will  have  purchased,  or  will  be in the  process  of
purchasing equivalent amounts of related securities or assets 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.
    
                                       7

<PAGE>

   
     As an  alternative  to  literal  compliance  with  the  bona  fide  hedging
definition,  a CFTC  regulation  permits  the  Fund to elect  to  comply  with a
different test, under which the aggregate  initial margin and premiums  required
to establish  speculative  positions in futures contracts and options on futures
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.  The
Fund will engage in  transactions  in options and futures  contracts only to the
extent such  transactions  are consistent with the  requirements of the Code for
maintaining  its  qualification  as a regulated  investment  company for Federal
income tax purposes.
    
     When the Fund  purchases  a  financial  futures  contract,  or writes a put
option or  purchases  a call  option  thereon,  cash and high grade  liquid debt
securities will be deposited in a segregated  account with the Fund's  custodian
in an amount that, together with the amount of initial and variation margin held
in the account of its broker, equals the market value of the futures contract.
   
     Lower Rated High Yield Debt  Obligations.  The Fund may invest up to 25% of
the value of its total  assets in fixed  income  securities  rated  below Baa by
Moody's Investors Service, Inc.  ("Moody's"),  or below BBB by Standard & Poor's
Ratings Group ("S&P"),  or in securities which are unrated.  The Fund may invest
in  securities  rated as low as Ca by Moody's or CC by S&P,  which may  indicate
that  the  obligations  are  highly  speculative  and in  default.  Lower  rated
securities are generally referred to as junk bonds. See the Appendix attached to
this Statement of Additional Information,  for the distribution of securities in
the various ratings  categories and a description of the  characteristics of the
categories.  The Fund is not  obligated to dispose of  securities  whose issuers
subsequently  are in  default  or which are  downgraded  below the  above-stated
ratings.  The Fund may invest in unrated securities which, in the opinion of the
Adviser, offer comparable yields and risks to those securities which are rated.
    
   
     Debt  obligations  rated in the  lower  ratings  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 economic, corporate and market developments to a
greater  extent  than do higher  rated  securities.  In the case of  lower-rated
securities,  these developments are perceived to have a more direct relationship
to the ability of an issuer of lower rated  securities  to meet its ongoing debt
obligations.
    
   
     Reduced volume and liquidity in the high yield bond market,  or the reduced
availability of market quotations, will make it more difficult to dispose of the
bonds and value  accurately  the Fund's  assets.  The  reduced  availability  of
reliable,  objective  data may  increase  the Fund's  reliance  on  management's

                                       8

<PAGE>

judgment in valuing the high yield bonds. To the extent that the Fund invests in
these  securities,  the achievement of the Fund's  objective will depend more on
the  Adviser's  judgment  and  analysis  than would  otherwise  be the case.  In
addition,  the Fund's investments in high yield securities may be susceptible to
adverse publicity and investor  perceptions,  whether or not the perceptions are
justified by fundamental  factors. In the past, economic downturns and increases
in interest  rates have caused a higher  incidence  of default by the issuers of
lower-rated securities and may do so in the future, particularly with respect to
highly leveraged issuers.  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 that pay interest  periodically  and in
cash.  Increasing rate note  securities are typically  refinanced by the issuers
within a short period of time. The Fund accrues  income on these  securities for
tax  and   accounting   purposes,   which  is  required  to  be  distributed  to
shareholders.  Because  no  cash is  received  while  income  accrues  on  these
securities,  the Fund may be forced to liquidate  other  investments to make the
distributions.
    
   
     The Fund may  acquire  individual  securities  of any  maturity  and is not
subject to any limits as to the average maturity of its overall  portfolio.  The
longer  the  Fund's  average  portfolio  maturity,  the  more  the  value of the
portfolio  and the net  asset  value of the  Fund's  shares  will  fluctuate  in
response to changes in  interest  rates.  An  increase  in  interest  rates will
generally  reduce the value of the Fund's  portfolio  securities  and the Fund's
shares, while a decline in interest rates will generally increase their value.
    
   
     Restricted  Securities.  The  Fund may  invest  in  restricted  securities,
including those eligible for resale to certain institutional  investors pursuant
to Rule 144A under the Securities Act of 1933 and foreign securities acquired in
accordance with Regulation S under the Securities Act of 1933. The Fund will not
invest more than 15% of its net assets in illiquid  investments,  which includes
repurchase agreements maturing in more than seven days, OTC options,  securities
that are not readily marketable and restricted securities. However, if the Board
of Trustees determines based upon a continuing review of the trading markets for
specific Rule 144A securities,  that they are liquid then such securities may be
purchased  without  regard to the 15%  limit.  The Board of  Trustees  may adopt
guidelines  and delegate to the Adviser the daily  function of  determining  and
monitoring  the liquidity of restricted  securities.  The Board,  however,  will
retain   sufficient   oversight   and  be   ultimately   responsible   for   the
determinations. The Board 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.
    
   
     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

                                       9

<PAGE>

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_% of its total assets.
    
   
     Repurchase Agreements. A repurchase agreement is a contract under which the
Fund would  acquire a security for a relatively  short period  (usually not more
than 7 days) subject to the  obligation of the seller to repurchase and the Fund
to resell such security at a fixed time and price  (representing the Fund's cost
plus 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 and could experience losses, including the
possible  decline in the value of the  underlying  securities  during the period
which the Fund seeks to enforce its rights thereto, possible subnormal levels of
income  and lack of access to income  during  this  period,  and the  expense of
enforcing its rights.
    
   
     Forward  Commitment  and  When-Issued  Securities.  The Fund  may  purchase
securities on a when-issued or forward commitment basis. "When-issued" refers to
securities  whose terms are available and for which a market  exists,  but which
have not been  issued.  The Fund will engage in  when-issued  transactions  with
respect to  securities  purchased  for its  portfolio in order to obtain what is
considered to be an advantageous price and yield at the time of the transaction.
For when-issued transactions,  no payment is made until delivery is due, often a
month or more after the purchase. In a forward commitment transaction,  the Fund
contracts  to  purchase  securities  for a fixed  price at a future  date beyond
customary settlement time.
    
   
     When the Fund engages in forward  commitment and when-issued  transactions,
it relies on the seller to consummate the transaction. The failure of the issuer
or seller to  consummate  the  transaction  may result in the Fund's  losing the
opportunity  to obtain a price  and yield  considered  to be  advantageous.  The
purchase  of  securities  on a when-  issued or  forward  commitment  basis also
involves a risk of loss if the value of the  security to be  purchased  declines
prior to the settlement date.
    
   
     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,  high grade debt securities equal in value to the Fund's
commitment.  These assets will be valued daily at market, and additional cash or

                                       10

<PAGE>

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.
    
   
     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
various  fixed income  securities  in order to realize  capital gains or improve
income.  Short term trading may have the effect of increasing portfolio turnover
rate. A high rate of portfolio turnover (100% or greater) involves corresponding
higher  transaction  expenses  and may  make it more  difficult  for the Fund to
qualify as a regulated  investment company for federal income tax purposes.  The
Fund intends to limit its short-term trading so that less than 30% of the Fund's
gross  annual  income will be derived from gross  realized  gains on the sale of
securities held for less than three months.
    
   
     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 borrowings 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  which are rated in the highest  rating  category by a
nationally  recognized  statistical rating organization (e.g., Standard & Poor's
Corporation  or  Moody's  Investors  Services,  Inc.)  or if  not so  rated,  of
equivalent investment quality in the opinion of the Adviser.
    
   
     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.
    
                                       11

<PAGE>

   
     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  servicers  to retain  possession  of the  underlying  obligations.  If the
servicer 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.
    
   
     Rights and  Warrants.  The Fund may invest up to 5% of its total assets (at
the time of purchase) in rights and warrants.  However, this limitation does not
apply to those  warrants or rights (i) acquired as part of a unit or attached to
other  securities  purchased  by  the  Fund  or  (ii)  acquired  as  part  of  a
distribution from the issuer.
    
   
     Structured or Hybrid Notes. The Fund may invest in "structured" or "hybrid"
notes.  The  distinguishing  feature of a structured  or hybrid note is that the
amount  of  interest  and/or  principal  payable  on the  note is  based  on the
performance of a benchmark asset or market other than fixed income securities or
interest  rates.  Examples of these  benchmarks  include stock prices,  currency
exchange rates and physical  commodity  prices.  Investing in a structured  note
allows  the Fund to gain  exposure  to the  benchmark  market  while  fixing the
maximum  loss that the Fund may  experience  in the event that  market  does not
perform as expected. Depending on the terms of the note, the Fund may forego all
or part of the  interest  and  principal  that would be payable on a  comparable
conventional  note; the Fund's loss cannot exceed this foregone  interest and/or
principal. An investment in structured or hybrid notes involves risks similar to
those associated with a direct investment in the benchmark asset.
    
   
     Swaps,  Caps,  Floor 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

                                       12

<PAGE>

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
counterparty's   ability  to   perform,   and  may   decline  in  value  if  the
counterparty's creditworthiness 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 entitlements
with respect to swap, cap, collar or floor transactions.
    
   
     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  are subject to its 15%  limitation on
investments   in  illiquid   securities.   The  Fund  may  purchase  only  those
participation  interest that mature in 60 days or less,  or, if maturing in more
than 60 days, that have a floating rate that is automatically  adjusted at least

INVESTMENT RESTRICTIONS

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

     The Fund observes the following fundamental restrictions:

                                       13

<PAGE>

     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
commitments,  forward  foreign  exchange  contracts  and  repurchase  agreements
entered into in accordance with the Fund's  investment  policy,  and the pledge,
mortgage or  hypothecation  of the Fund's assets within the meaning of paragraph
(3) below are not deemed to be senior securities.
    
     (2)  Borrow   money,   except  from  banks  as  a  temporary   measure  for
extraordinary  emergency purposes in amounts not to exceed 33 1/3% of the Fund's
total assets  (including the amount  borrowed)  taken at market value.  The Fund
will not use leverage to attempt to increase income.  The Fund will not purchase
securities while outstanding borrowings exceed 5% of the Fund's total assets.

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

     (8) Purchase the securities of issuers  conducting their principal business
activity in the same industry if, immediately after such purchase,  the value of

                                       14

<PAGE>

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

          (a) Such purchase  would cause more than 5% of the Fund's total assets
taken at market value to be invested in the securities of such issuer, or

          (b) 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  by  cash or
securities of the U.S. Government or its agencies or  instrumentalities  and the
Fund's custodian must take possession of the collateral  either physically or in
book entry form.  Any cash  collateral  will consist of short-term  high quality
debt instruments. Securities used as collateral must be marked to market daily.

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

     The Fund may not:

     (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
securities trading account.

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

     (c)  Purchase a security  if, as a result,  (i) more than 10% of the Fund's
total assets would be invested in securities of closed-end investment companies,
(ii) such purchase would result in more than 3% of the total outstanding  voting
securities of any one such closed-end investment company being held by the Fund,

                                       15

<PAGE>

or (iii) more than 5% of the Fund's  total  assets  would be invested in any one
such closed-end  investment company.  The Fund will not invest in the securities
of any open-end investment company.

     (d) Purchase securities of any issuer which, together with any predecessor,
has a record  of less  than  three  years'  continuous  operations  prior to the
purchase  if such  purchase  would  cause  investments  of the  Fund in all such
issuers to exceed 5% of the value of the total assets of the Fund.

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

     (f)  Purchase  warrants of any issuer,  if, as a result of such  purchases,
more  than 2% of the value of the  Fund's  total  assets  would be  invested  in
warrants  which are not listed on the New York Stock  Exchange  or the  American
Stock  Exchange  or more than 5% of the  value of the  total  assets of the Fund
would be  invested in warrants  generally,  whether or not so listed.  For these
purposes,  warrants are to be valued at the lesser of cost or market value,  but
warrants acquired by the Fund in units with or attached to debt securities shall
be deemed to be without value.

     (g) Knowingly  purchase or retain securities of an issuer if one or more of
the  Trustees or officers of the Fund or directors or officers of the Adviser or
any  investment   management   subsidiary  of  the  Adviser   individually  owns
beneficially  more than 0.5%, and together own beneficially more than 5%, of the
securities of such issuer.

     (h) Purchase  interests in oil, gas or other mineral  leases or exploration
programs;  however,  this policy will not prohibit the acquisition of securities
of companies  engaged in the  production  or  transmission  of oil, gas or other
minerals.

     (i) Invest more than (i) 10% of its total  assets in  securities  which are
restricted  under  the  Securities  Act of  1933  (the  "1933  Act")  (excluding
restricted  securities  that are eligible for resale pursuant to Rule 144A under
the  1933  Act)  or (ii)  15% of the  Fund's  total  assets  in such  restricted
securities (including restricted securities eligible for resale pursuant to Rule
144A).

     (j) Purchase interests in real estate limited partnerships.

     (k) Purchase any security,  including any repurchase  agreement maturing in
more than seven days, which is not readily  marketable,  if more than 15% of the
net  assets  of the Fund,  taken at  market  value,  would be  invested  in such
securities.  (The staff of the  Securities  and  Exchange  Commission  considers
over-the-counter options to be illiquid securities subject to the 15% limit.)

     (l)  Notwithstanding any investment  restriction to the contrary,  the Fund
may, in connection  with the John Hancock Group of Funds  Deferred  Compensation

                                       16

<PAGE>

Plan for Independent Trustees/Directors, purchase securities of other investment
companies within the John Hancock Group of Funds provided that, as a result, (i)
no more than 10% of the Fund's  assets  would be invested in  securities  of all
other investment companies,  (ii) such purchase would not result in more than 3%
of the total outstanding  voting  securities of any one such investment  company
being held by the Fund and (iii) no more that 5% of the Fund's  assets  would be
invested in any one such investment company.

     In order to permit  the sale of shares of the Fund in certain  states,  the
Trustees may, in their sole discretion,  adopt restrictions on investment policy
more restrictive than those described above.  Should the Trustees determine that
any such more  restrictive  policy is no longer in the best interest of the Fund
and its  shareholders,  the Fund may cease offering shares in the state involved
and the Trustees may revoke such  restrictive  policy.  Moreover,  if the states
involved shall no longer require any such restrictive  policy, the Trustees may,
at their sole discretion, revoke such policy.
   
     If a percentage  restriction  on investment or utilization of assets as set
forth above is adhered to at the time an  investment  is made, a later change in
percentage  resulting from changes in the value of the Fund's assets will not be
considered a violation of the restriction.
    
THOSE RESPONSIBLE FOR MANAGEMENT

     The business of the Fund is managed by 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

     As described in the  Prospectus,  the Fund receives its  investment  advice
from the Adviser.  Investors should refer to the Prospectus for a description of
certain information concerning the investment management contract.

     Each of the  Trustees  and  principal  officers  of the Fund who is also an
affiliated  person of the Adviser is named above,  together with the capacity in
which such person is affiliated with the Fund and the Adviser.
   
     As  described  in  the  Prospectus  under  the  caption  "Organization  and
Management  of the Fund," the Fund has  entered  into an  investment  management
contract with the Adviser. Under the investment management contract, the Adviser
provides the Fund (i) with a continuous investment program,  consistent with the
Fund's  stated  investment  objective and policies and (ii)  supervision  of all
aspects of the Fund's operations except those delegated to a custodian, transfer
agent or other  agent.  The Adviser is  responsible  for the  management  of the
Fund's portfolio assets.
    
     Securities  held by the Fund may also be held by other funds or  investment
advisory  clients for which the Adviser or its  affiliates  provides  investment
advice.   Because  of  different  investment  objectives  or  other  factors,  a
particular  security  may be bought for one or more funds or clients when one or
more other funds or clients are selling the same security.  If opportunities for
the purchase or sale of securities by the Adviser or for other funds or clients,
for which the Adviser renders investment  advice,  arise for consideration at or
about the same time,  transactions in such  securities will be made,  insofar as
feasible,  for the respective  funds or clients in a manner deemed  equitable to
all of them. To the extent that  transactions  on behalf of more than one client
of the Adviser or its affiliates  may increase the demand for  securities  being
purchased or the supply of securities being sold, there may be an adverse effect
on price.

                                       24

<PAGE>

     No person other than the Adviser and its directors and employees  regularly
furnishes  advice to the Fund with  respect  to the  desirability  of the Fund's
investing  in,  purchasing or selling  securities.  The Adviser may from time to
time receive statistical or other similar factual  information,  and information
regarding  general  economic  factors and trends,  from the Life Company and its
affiliates.
   
    
     All expenses which are not  specifically  paid by the Adviser and which are
incurred in the  operation of the Fund  (including  fees of Trustees of the Fund
who are not  "interested  persons,"  as such term is defined  in the  Investment
Company Act, but excluding certain  distribution  related activities required to
be paid by the Adviser or John Hancock Funds) and the continuous public offering
of the shares of the Fund are borne by the Fund.

     As  provided  by the  investment  management  contract,  the Fund  pays the
Adviser  monthly  an  investment  management  fee,  which  is  based on a stated
percentage of the Fund's average of the daily net assets as follows:

          Net Asset Value                    Annual Rate
          ---------------                    -----------
       First $1,500,000,000                      0.50%
        Next $500,000,000                        0.45%
        Next $500,000,000                        0.40%
    Amount over $2,500,000,000                   0.35%

     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.

     On December 31, 1995, the net assets of the Fund were  $1,633,942,540.  For
the years ended December 31, 1993,  1994, and 1995 the Adviser  received fees of
$6,488,835  and  $7,116,092  and  $7,406,635,  respectively.  The  1992 and 1993
advisory fee figures  reflect the  different  advisory fee schedule  that was in
effect before January 1, 1994.

     If the total of all ordinary  business  expenses of the Fund for any fiscal
year exceeds limitations prescribed by any state in which shares of the Fund are
qualified for sale, the fee payable to the Adviser will be reduced to the extent
required  by these  limitations.  At this time,  the most  restrictive  limit on
expenses  imposed by a state  requires that expenses  charged to the Fund in any
fiscal year not exceed 2 1/2% of the first $30,000,000 of the Fund's average net
assets,  2% of the  next  $70,000,000  of  such  net  assets,  and 1 1/2% of the

                                       25

<PAGE>

remaining  average net assets.  When  calculating the above limit,  the Fund may
exclude interest, brokerage commissions and extraordinary expenses.

     Pursuant to its investment  management contract,  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
investment  management  contract  relates,  except a loss resulting from willful
misfeasance,  bad faith or gross  negligence  on the part of the  Adviser in the
performance  of its  duties or from  reckless  disregard  by the  Adviser of its
obligations and duties under the investment management contract.
   
     The  Adviser,  located  at 101  Huntington  Avenue,  Boston,  Massachusetts
02199-7603,  was  organized in 1968 and  presently  has more than $18 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  1,080,000  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 $80  billion,  the Life  Company is one of the ten  largest  life
insurance  companies in the United  States,  and carries high ratings from S&P's
and A. M. Best.  Founded in 1862, the Life Company has been serving  clients for
over 130 years.
    
     Under the investment  management contract,  the Fund may use the name "John
Hancock"  or any  name  derived  from or  similar  to it only for so long as the
contract or any extension,  renewal or amendment  thereof remains in effect.  If
the  contract  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 investment management contract continues in effect from year to year if
approved  annually by vote of a majority of the Trustees who are not  interested
persons  of one of the  parties  to the  contract,  cast in  person at a meeting
called for the purpose of voting on such approval, and by either the Trustees or
the  holders of a majority  of the Fund's  outstanding  voting  securities.  The
contract automatically  terminates upon assignment and may be terminated without
penalty on 60 days'  notice at the option of either  party to the contract or by
vote of a majority of the outstanding voting securities of the Fund.

DISTRIBUTION CONTRACT

     The Fund has a  distribution  contract with John Hancock  Funds.  Under the
contract, John Hancock Funds is obligated to use its best efforts to sell shares
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.  In connection  with the sale of Class A and
Class B shares,  John Hancock Funds and Selling Brokers receive  compensation in
the form of a sales charge imposed,  in the case of Class A shares,  at the time
of sale or,  in the case of Class B  shares,  on a  deferred  basis.  The  sales
charges are discussed further in the Prospectus.
   
     The Fund's Trustees adopted  Distribution Plans with respect to the 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% for Class A and Class
B, respectively,  of the Fund's daily net assets  attributable to shares of that
class.  However,  the service fee will not exceed  0.25% of the Fund's daily net
assets  attributable to each class of shares. The distribution fees will be used
to reimburse the Distributor for its  distribution  expenses,  including but not
limited to: (i) initial and ongoing sales  compensation  to Selling  Brokers and
others  (including  affiliates of the  Distributor)  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 for providing  personal and account
maintenance  services to  shareholders.  In the event that John Hancock Funds is
not fully  reimbursed for expenses  incurred by it under the Class B Plan in any
fiscal year,  John Hancock  Funds may carry these  expenses  forward,  provided,
however that the Trustees may terminate the Class B Plan and,  thus,  the Fund's
obligation to make further payments at any time. Accordingly,  the Fund does not
treat unreimbursed expenses relating to the Class B shares as a liability of the
Fund.  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.
    
     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.

     During the fiscal year ended  December  31, 1995 the Fund paid John Hancock
Funds the  following  amounts of expenses with respect to the Class A shares and
Class B shares of the Fund:

</TABLE>

     Each of the Plans  provides that it 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.  Each  of the  Plans  provides  that  it may be
terminated  without  penalty  (a) by  vote  of a  majority  of  the  Independent
Trustees,  (b) by 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.  Each of the Plans further  provides
that it 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. And finally,  each of the Plans provides that no material amendment to the
Plan will,  in any event,  be  effective  unless it is approved by a vote of the
Trustees and the Independent Trustees of the Fund. The holders of Class A shares
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 each Plan will benefit the holders of the applicable class of shares of the
Fund.

     When the Fund  seeks  an  Independent  Trustee  to fill a  vacancy  or as a
nominee  for  election by  shareholders,  the  selection  or  nomination  of the
Independent   Trustee   is,   under   resolutions   adopted   by  the   Trustees
contemporaneously  with their adoption of the Plans, committed to the discretion
of the Committee on Administration of the Trustees. The members of the Committee
on  Administration  are all  Independent  Trustees  and are  identified  in this
Statement of Additional  Information  under the heading "Those  Responsible  for
Management."

NET ASSET VALUE

     For purposes of calculating the net asset value ("NAV") of a 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.

     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 Fund will not price its securities on the following  national holidays:
New Year's Day;  Presidents' Day; Good Friday;  Memorial Day;  Independence Day;
Labor Day;  Thanksgiving  Day; and  Christmas  Day. 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.  Trading of foreign securities may take
place on  Saturdays  and U.S.  business  holidays  on which a Fund's  NAV is not
calculated. Consequently, a 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
   
     Class A 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 owned
by the investor,  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  Investor  Services  Inc.
(Investor  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.
    
     Combined Purchases. In calculating the sales charge applicable to purchases
of Class A shares made at one time,  the  purchases  will be combined if made by
(a) an individual, his 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) certain
groups of four or more  individuals  making use of salary  deductions or similar
group  methods of payment  whose funds are  combined  for the purchase of mutual
fund shares.  Further  information about combined  purchases,  including certain
restrictions on combined group purchases, is available from Investor Services or
a Selling Broker's representative.

                                       29

     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.

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, mother,
     father,  sister,  brother,  mother-in-law,  father-in-law)  of  any  of the
     foregoing;  or any fund, pension, profit sharings 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.

     Class A shares may also be  acquired  without an  initial  sales  charge in
connection  with  certain  liquidation,   merger  or  acquisition   transactions
involving other investment companies or personal holding companies.
    
     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  already held by
such person.

     Combination Privilege. Reduced sales charges (according to the schedule set
forth  in the  Prospectus)  also  are  available  to an  investor  based  on the
aggregate  amount of his concurrent  and prior  investments in Class A shares of
the Fund and shares of all other John Hancock funds which carry a sales charge.

     Letter of  Intention.  The reduced  sales  charges are also  applicable  to
investments  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

                                       30

<PAGE>

using the Fund as a funding medium for a qualified retirement plan, however, may
opt to make the necessary  investments  called for by the LOI over a forty-eight
(48) month  period.  These  qualified  retirement  plans include group IRA, SEP,
SARSEP, TSA, 401(k), 403(b) 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 Investor 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
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  Investor  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 Class A shares held in escrow may be redeemed and
the proceeds used as required to pay such sales charge as may be due. By signing
the  LOI,  the  investor  authorizes  Investor  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 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 that 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. Accordingly, no CDSC will be imposed on increases
in account value above the initial  purchase  prices,  including  Class B shares
derived from reinvestment of dividends or capital gains  distributions.  No CDSC
will be imposed on shares  derived  from  reinvestment  of  dividends or capital
gains distributions.
    
   
     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 this number,  all

                                       31

<PAGE>

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.  Upon redemption,  appreciation is effective only on a per share
basis for those shares being redeemed. Appreciation of shares cannot be redeemed
CDSC free at the account level.
    
   
     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:

*    Proceeds of 50 shares redeemed at $12 per share                       $600
*    Minus proceeds of 10 shares not subject to CDSC 
     (dividend reinvestment)                                               -120
*    Minus appreciation on remaining shares (40 shares X $2)                -80
                                                                           ----
*    Amount subject to CDSC                                                $400
    

     Proceeds from the CDSC are paid to John Hancock Funds and are used in whole
or in part by John  Hancock  Funds to defray its  expenses  related to providing
distribution-related  services  to the Fund in  connection  with the sale of the
Class B shares,  such as the payment of  compensation  to select Selling Brokers
for selling Class B shares. The combination of the CDSC and the distribution and
service  fees  facilitates  the  ability  of the Fund to sell the Class B shares
without a sales  charge  being  deducted  at the time of the  purchase.  See the
Prospectus for additional information regarding the CDSC.
   
     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 circumstances defined below:
    
                                       32
<PAGE>

   
*    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.

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

*    Redemptions  made to effect  mandatory  distributions  under  the  Internal
     Revenue Code after age 70 1/2.
*    Returns of excess contributions made to these plans.
*    Redemptions  made to effect  distributions to participants or beneficiaries
     from employer  sponsored  retirement  plans such as 401k, 403b, 457. In all
     cases, the distribution must be free from penalty under the Code.
*    Redemptions  made to effect  distributions  from an  Individual  Retirement
     Account  either  before  age 59 1/2 or  after  age 59  1/2,  as long as the
     distributions  are  based on your  life  expectancy  or the  joint-and-last
     survivor life expectancy of you and your beneficiary.  These  distributions
     must be free from penalty  under the Code. 
*    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.

For non-retirement accounts (please see above for retirement account waivers):

*    Redemptions  of Class B shares made under a periodic  withdrawal  plan,  as
     long as your annual  redemptions do not exceed 10% of your account value at
     the time you established your periodic withdrawal plan and 10% 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.)

Please see matrix for reference.

If you qualify for a CDSC waiver under one of these situations,  you must notify

waiver.
    

SPECIAL REDEMPTIONS

     Although  it would not  normally  do so,  the Fund has the right to pay the
redemption  price  of  shares  of the  Fund in  whole  or in  part in  portfolio
securities as prescribed by the Trustees.  When the shareholder  sells portfolio
securities received in this fashion, he would 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.

                                       34

ADDITIONAL SERVICES AND PROGRAMS

     Exchange  Privilege.  As described more fully in the  Prospectus,  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.
   
     Systematic  Withdrawal  Plan. As described  briefly in the Prospectus,  the
Fund permits the establishment of a Systematic  Withdrawal Plan.  Payments under
this plan  represent  proceeds  from the  redemption  of Fund shares.  Since the
redemption  price of the Fund shares may be more or less than the  shareholder's
cost, depending upon the market value of the securities owned by the Fund at the
time of redemption, the distribution of cash pursuant to this plan may result in
recognition  of gain or loss for  purposes  of Federal,  state and local  income
taxes.  The  maintenance  of a  Systematic  Withdrawal  Plan  concurrently  with
purchases  of  additional  Class A or  Class  B  shares  of the  Fund  could  be
disadvantageous to a shareholder  because of the initial sales charge payable on
such  purchases of Class A shares and the CDSC imposed on redemptions of Class B
shares and because  redemptions  are taxable  events.  Therefore,  a shareholder
should  not  purchase  Class A and Class B shares of the Fund 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 Investor Services.
    
     Monthly Automatic Accumulation Program ("MAAP").  This program is explained
more fully in the Prospectus. The program, as it relates to automatic investment
checks, is subject to the following conditions:

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

     The  privilege  of  making   investments   through  the  Monthly  Automatic
Accumulation Program may be revoked by Investor 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
Investor  Services or upon written notice to Investor Services which is received
at least five (5) business days prior to the processing date of any investment.

     Reinvestment  Privilege.  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 in any other 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

                                       35

<PAGE>

the Fund or in Class A shares of other John  Hancock  funds.  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.  The Fund may  modify or
terminate the reinvestment privilege 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."

DESCRIPTION OF THE FUND'S SHARES

     The Trustees of the Fund 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 not authorized any additional series of the Fund,
other than the Fund,  although they may do so in the future.  The Declaration of
Trust also  authorizes the Trustees to classify and reclassify the shares of the
Fund, or any other 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 two classes of shares of the Fund, designated as Class A and Class B
shares.

     Class A and Class B shares  of the Fund  represent  an equal  proportionate
interest in the aggregate net assets attributable to that class of the Fund.

     The  holders of Class A shares and Class B shares  have  certain  exclusive
voting rights on matters  relating to their  respective Rule 12b-1  distribution
plans.
   
     Dividends  paid by the Fund,  if any,  with respect to each class of shares
will be calculated in the same manner,  at the same time and on the same day and
will be in the same amount, except for differences resulting from the facts that
(i) the  distribution  and service  fees  relating to Class A and Class B shares
will be borne  exclusively  by that  class,  (ii) Class B shares will pay higher
distribution and service fees than Class A shares and (iii) each class of shares
will  bear any other  class  expenses  properly  attributable  to that  class of
shares,  subject to the conditions  imposed by the Internal  Revenue  Service in
issuing rulings to funds with a  multiple-class  structure.  Similarly,  the net
asset value per share may vary depending on the class of shares purchased.
    
                                       36

<PAGE>

   
     In the event of liquidation, shareholders are entitled to share pro rata in
the net assets of the Fund  available  for  distribution  to such  shareholders.
Shares entitle their holders to one vote per share, are freely  transferable and
have no preemptive,  subscription or conversion rights. When issued,  shares are
fully paid and non-assessable by the Fund, except as set forth below.
    
     Unless otherwise  required by the Investment Company Act or the Declaration
of Trust,  the Fund has no intention of holding annual meetings of shareholders.
Fund  shareholders  may  remove a Trustee  by the  affirmative  vote of at least
two-thirds of the Fund's outstanding shares and the Trustees shall promptly call
a meeting  for such  purpose  when  requested  to do so in writing by the record
holders of not less than 10% of the outstanding shares of the Fund. Shareholders
may,  under  certain  circumstances,  communicate  with  other  shareholders  in
connection with requesting a special meeting of  shareholders.  However,  at any
time that less than a majority of the  Trustees  holding  office were elected by
the  shareholders,  the Trustees will call a special meeting of shareholders for
the purpose of electing Trustees.

     Under  Massachusetts  law,  shareholders of a Massachusetts  business trust
could,  under  certain  circumstances,  be held  personally  liable  for acts or
obligations of the Fund.  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  Fund  shareholder  held
personally liable by reason of being or having been a shareholder.  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.
   
     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.
    

TAX STATUS
   
     The Fund has  qualified  and has  elected  to be  treated  as a  "regulated
investment  company" under  Subchapter M of 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 taxable income  (including net realized capital
gains,  if any) which is  distributed  to  shareholders  in accordance  with the
timing requirements of the Code.
    
                                       37

<PAGE>

   
     The Fund will be subject to a four percent  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 long-term  capital gain. (Net
capital  gain is the  excess  (if any) of net  long-term  capital  gain over net
short-term  capital loss, and investment  company  taxable income is all taxable
income and  capital  gains,  other than net capital  gain,  after  reduction  by
deductible  expenses.) Some distributions from investment company taxable income
and/or  net  capital  gain  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.
    
   
     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 that will generate  capital gains or to enter into options
or futures transactions. At the time of an investor's purchase of Fund shares, a
portion of the purchase  price is often  attributable  to realized or unrealized
appreciation in the Fund's portfolio. Consequently,  subsequent distributions on
these shares from such  appreciation may be taxable to such investor even if the
net asset value of the investor's  shares is, as a result of the  distributions,
reduced below the  investor's  cost for such shares,  and the  distributions  in
reality represent a return of a portion of the purchase price.
    
   
     Upon a  redemption  of shares of the Fund  (including  by  exercise  of the
exchange privilege) a shareholder will ordinarily realize a taxable gain or loss
depending  upon the  amount  of the  proceeds  and the  investor's  basis in his
shares.  Such gain or loss will be treated as capital gain or loss if the shares
are  capital  assets  in the  shareholder's  hands  and  will  be  long-term  or
short-term,  depending upon the  shareholder's tax holding period for the shares
and  subject to the  special  rules  described  below.  A sales  charge  paid in
purchasing  Class A shares of the Fund cannot be taken into account for purposes

                                       38

<PAGE>

of determining  gain or loss on the redemption or exchange of such shares within
ninety (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 sixty- one (61) days  beginning
thirty  (30) days  before  and  ending  thirty  (30) days  after the  shares are
disposed of, such as pursuant to  automatic  dividend  reinvestments.  In such a
case,  the  basis  of the  shares  acquired  will be  adjusted  to  reflect  the
disallowed  loss.  Any loss  realized  upon the  redemption of shares with a tax
holding period of six months or less will be 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.
    
   
     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  long-term
capital  gain in his  return for his  taxable  year in which the last day of the
Fund's taxable year falls,  (b) be entitled either to a tax credit on his return
for,  or to a refund of,  his pro rata share of the taxes paid by the Fund,  and
(c) be entitled to increase the adjusted tax basis for his shares in the Fund by
the difference  between his pro rata share of this excess and his pro rata share
of these taxes.
    
   
     For Federal  income tax purposes,  the Fund is permitted to carry forward a
net capital  loss in any year to offset net capital  gains,  if any,  during the
eight years following the year of the loss. To the extent subsequent net capital
gains are offset by such  losses,  they  would not result in Federal  income tax
liability  to the  Fund  and,  as  noted  above,  would  not be  distributed  to
shareholders.  The Fund has $20,654,741 of capital loss carryforwards available,
to the extent  provided by  regulations,  to offset future net realized  capital
gains. These carryforwards expire at various amounts and times from 1996 through
2002.
    
   
     Dividends and capital gain distributions from the Fund will not qualify for
the dividends-received deduction for corporations.
    
                                       39

<PAGE>

     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 may be subject to  withholding  and other taxes imposed by foreign
countries with respect to the Fund's investments in certain foreign  securities,
if any. Tax  conventions  between  certain  countries and the U.S. may reduce or
eliminate  such taxes in some cases.  Because more than 50% of the Fund's assets
at the  close of any  taxable  year  will  generally  not  consist  of stocks or
securities of foreign  corporations,  the Fund will  generally be unable to pass
through such taxes to its  shareholders,  who will  therefore  generally  not be
entitled to any foreign tax credit or deduction with respect to their investment
in the Fund.  The Fund will deduct such taxes in  determining  the amount it has
available for distribution to shareholders.
    
   
     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  rules  applicable  to certain  options  and futures  contracts  may also
require the Fund to recognize gain within a concurrent receipt of cash. However,
the Fund must distribute to shareholders for each taxable year substantially all
of its net income and net capital gains,  including such income or 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
may have to leverage itself by borrowing the 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  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

                                       40

<PAGE>

IRS or a broker  notifies the Fund that the number  furnished by the shareholder
is  incorrect  or that the  shareholder  is subject to backup  withholding  as a
result of failure to report interest or dividend income.  The Fund may refuse to
accept an application that does not contain any required taxpayer identification
number or  certification  that the number  provided  is  correct.  If the backup
withholding  provisions are  applicable,  any such  distributions  and proceeds,
whether taken in cash or  reinvested  in shares,  will be reduced by the amounts
required  to be  withheld.  Any  amounts  withheld  may be  credited  against  a
shareholder's U.S. federal income tax liability.  Investors should consult their
tax advisers about the applicability of the backup withholding provisions.
    
     The Fund may  invest  in debt  obligations  that  are in the  lower  rating
categories or are unrated,  including debt  obligations of issuers not currently
paying  interest  as well as issuers  who are in  default.  Investments  in debt
obligations that are at risk of or in default present special tax issues for the
Fund.  Tax rules are not  entirely  clear about issues such as when the Fund may
cease to accrue interest,  original issue discount, or market discount, when and
to what extent  deductions  may be taken for bad debts or worthless  securities,
how payments  received on  obligations  in default  should be allocated  between
principal and income,  and whether  exchanges of debt  obligations  in a workout
context are taxable.  These and other  issues will be addressed by the Fund,  in
the  event  it  invests  in such  securities,  in order  to  reduce  the risk of
distributing   insufficient  income  to  preserve  its  status  as  a  regulated
investment  company  and seek to avoid  becoming  subject to  Federal  income or
excise tax.
   
     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.  Also,  some of the  Fund's  losses on its  transactions  involving
options and futures contracts and/or offsetting or successor portfolio positions
may be deferred  rather than being taken into account  currently in  calculating
the Fund's taxable income or gain.  Certain of such  transactions may also cause
the Fund to dispose of  investments  sooner than would  otherwise have occurred.
These transactions may thereafter affect the amount, timing and character of the
Fund's  distributions to  shareholders.  Some of the applicable tax rules may be
modified if the Fund is eligible  and chooses to make one or more of certain tax
elections that may be available. The Fund will take into account the special tax
rules (including consideration of available elections) applicable to options and
futures  transactions  in order to seek to minimize  any  potential  adverse tax
consequences.
    
   
     The foregoing  discussion  relates solely to U.S. Federal income tax law as
applicable to U.S. persons (i.e.,  U.S.  citizens or residents and U.S. domestic
corporations,  partnerships,  trusts or estates)  subject to tax under such law.
The discussion does not address special tax rules  applicable to certain classes

                                       41

<PAGE>

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 shares of the Fund may
also be subject to state and local taxes.  Shareholders should consult their own
tax advisers as to the Federal,  state or local tax consequences of ownership of
shares  of, and  receipt of  distributions  from,  the Fund in their  particular
circumstances.
    
   
     Non-U.S. investors not engaged in a U.S. trade or business with which their
Fund investment is effectively  connected will be subject to U.S. Federal income
tax treatment that is different from that described  above.  These investors may
be subject to nonresident  alien  withholding tax at the rate of 30% (or a lower
rate under an applicable tax treaty),  on amounts treated as ordinary  dividends
from the Fund and, unless an effective IRS Form W-8 or authorized substitute for
Form W-8 is on file, to 31% backup  withholding  on certain other  payments from
the Fund.  Non-U.S.  investors should consult their tax advisors  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.  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  December 31, 1995,  the  annualized  yield on
Class A and Class B shares of the Fund was 5.88% and  5.46%,  respectively.  The
average  annual total return of the Class A shares of the Fund for the 1 year, 5
year and 10 year periods  ended  December 31, 1995 was 14.11%,  9.33% and 9.01%,
respectively and reflect payment of the maximum sales charge of 4.50%.

     The  average  annual  total  return of Class B shares of the Fund for the 1
year period ended December 31, 1995 and since inception on November 19, 1993 was
13.71% and 5.96%,  respectively.  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:

                                       42

<PAGE>

                        Yield = 2 ([(a - b) + 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, 5 year and 10 year periods that would
equate the initial amount invested to the ending  redeemable  value according to
the following formula:

                                    n ______
                               T = \ / ERV/P - 1

Where:

         P =      a hypothetical initial investment of $1,000.

         T =      average annual total return.

         n =      number of years.

         ERV =    ending redeemable  value of  hypothetical  $1,000 investment 
                  made at the  beginning  of the 1 year, 5 year and life-of-fund
                  periods.

     In the case of Class A shares or Class B shares,  this calculation  assumes
the  maximum  sales  charge of 4.5% and 5.0%,  respectively,  is included in the
initial  investment  or the  CDSC  applied  at  the  end  of  the  period.  This

                                       43

<PAGE>

calculation also assumes that all dividends and  distributions are reinvested at
net asset value on the reinvestment dates during the period.

     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 4.5% sales charge
on  Class  A  shares  or the 5%  CDSC  on  Class  B  shares  into  account.  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  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 total
return  will be ranked or  compared  to indices  of mutual  funds such as Lipper
Analytical Services,  Inc.'s  "Lipper"-Mutual  Performance  Analysis," a monthly
publication  which tracks net assets,  total return,  and yield on equity 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.

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

     The  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 its investment committee, 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  Adviser,  will offer the best
price and market for the  execution  of each such  transaction.  Purchases  from
underwriters  of portfolio  securities  may include a commission or  commissions
paid by the issuer  and  transactions  with  dealers  serving  as market  makers

                                       44

<PAGE>

reflect a "spread." Investments in debt securities are generally traded on a net
basis  through  dealers  acting for their own account as  principals  and not as
brokers; no brokerage commissions are payable on such transactions.

     The  Fund's  primary  policy  is to  execute  all  purchases  and  sales of
portfolio  instruments  at  the  most  favorable  prices  consistent  with  best
execution,  considering all of the costs of the transaction  including brokerage
commissions.  This policy  governs the  selection of brokers and dealers and the
market in which a transaction is executed. Consistent with the foregoing primary
policy,  the Rules of Fair  Practice of the National  Association  of Securities
Dealers, Inc. and 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 in 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 Adviser  will be primarily
responsible for the allocation of the Fund's brokerage business,  their policies
and  practices  of the  Adviser  in this  regard  must be  consistent  with  the
foregoing  and will at all times be subject to review by the  Trustees.  For the
years ended on December  31,  1995,  1994,  and 1993,  no  negotiated  brokerage
commissions were paid on portfolio transactions.

     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 December 31,
1995,  the Fund did not pay  commissions  to  compensate  brokers  for  research
services  such as industry,  economic  and company  reviews and  evaluations  of
securities.
   
     The  Adviser's  indirect  parent,  the Life  Company,  is the indirect sole
shareholder of John Hancock Freedom Securities Corporation and its subsidiaries,
Tucker Anthony Incorporated,  John Hancock Distributors,  Inc.  ("Distributors")

                                       45

<PAGE>

and Sutro & Company, Inc., ("Sutro") (each an "Affiliated Broker").  Pursuant to
procedures  established 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 years ended December 31, 1995, 1994 and
1993,  the Fund did not  execute  any  portfolio  transactions  with  Affiliated
Brokers.
    
   
     Any of the  Affiliated  Brokers  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 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 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.  The Fund will not effect
principal transactions with Affiliated Brokers.
    
TRANSFER AGENT SERVICES
   
     John Hancock Investor Services Corporation ("Investor Services"),  P.O. Box
9116,  Boston,  MA 02205-9116,  a wholly-owned  indirect  subsidiary of the Life
Company, is the transfer and dividend paying agent of the Fund. The Fund pays an
annual  fee of $20.00  per Class A  shareholder  account  and $22.50 per Class B
shareholder account,  plus certain  out-of-pocket  expenses.  These expenses are
aggregated  and charged to the Fund and  allocated to each class on the basis of
the 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, 24 Federal Street,  Boston,
Massachusetts  02110.  Under the  custodian  agreement,  Investors  Bank & Trust
Company performs custody, portfolio and fund accounting services.

APPENDIX

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

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  characterized
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 represented obligations which are speculative in a high
degree. Such issues are often in default or have other marked shortcomings.

Bonds which are rated C are the lowest  rated class of bonds and issues so rated
can be regarded as having  extremely  poor  prospects of ever attaining any real
investment standing.

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

Debt rated 'BBB' is regarded as having an 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  protections;  (4) broad  margins in  earnings  coverage of
fixed  financial  charges  and  high  internal  cash  generation;  and (5)  well
established  access to a range of  financial  markets  and  assured  sources  of
alternate liquidity.

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.

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

BBB Debt rated BBB is regarded as having an  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.

BB, B, CCC, CC, C Debt rated 'BB',  'B',  'CCC',  'CC" and 'C' is  regarded,  on
balance,  as predominantly  speculative with respect to capacity to pay interest
and  repay  principal  in  accordance  with the  terms of the  obligation.  'BB'
indicates  the  lowest  degree  of  speculation  and 'C' 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.

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

                                      A-2

<PAGE>

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

CCC Debt rated 'CCC' has a currently identifiable  vulnerability to default, and
is dependent upon favorable business, financial, and economic conditions to meet
timely  payment of interest and repayment of principal.  In the event of adverse
business,  financial  or  economic  conditions,  it is not  likely  to have  the
capacity to pay interest and repay principal.  The 'CCC' rating category is also
used for debt  subordinated to senior debt that is assigned an actual or implied
'B' or 'B-' rating.

CC The rating 'CC' is typically applied to debt subordinated to senior debt that
is assigned an actual or implied 'CCC' rating.

C The rating 'C' is typically  applied to debt subordinated to senior debt which
is assigned an actual or implied 'CCC-' debt rating.  The 'C' rating may be used
to cover a  situation  where a  bankruptcy  petition  has been  filed,  but debt
service payments are continued.

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

A-1.  This  designation  indicated  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.

Item 27. Indemnification

     Section 4.3 of  Registrant's  Declaration  of Trust provides that (i) every
     person who is, or has been,  a Trustee,  officer,  employee or agent of the
     Trust  (including  any  individual  who serves at its request as  director,
     officer,  partner,  trustee or the like of another organization in which it
     has  any  interest  as a  shareholder,  creditor  or  otherwise)  shall  be
     indemnified  by the Trust,  or by one or more  Series  thereof if the claim
     arises from his or her conduct  with


                                      C-1

<PAGE>

     respect to only such Series, to the fullest extent permitted by law against
     all liability and against all expenses  reasonably  incurred or paid by him
     in  connection  with any  claim,  action,  suit or  proceeding  in which he
     becomes  involved as a party or  otherwise by virtue of his being or having
     been a Trustee or officer  and against  amounts  paid or incurred by him in
     the settlement thereof;  and that (ii) the words "claim," "action," "suit,"
     or "proceeding"  shall apply to all claims,  actions,  suits or proceedings
     (civil, criminal, or other, including appeals),  actual or threatened;  and
     the words  "liability" and "expenses"  shall include,  without  limitation,
     attorneys'  fees,  costs,  judgments,  amounts paid in  settlement,  fines,
     penalties and other liabilities.

     However,  no indemnification  shall be provided to a Trustee or officer (i)
     against any liability to the Trust, a Series thereof or the Shareholders by
     reason of willful  misfeasance,  bad faith,  gross  negligence  or reckless
     disregard  of the duties  involved in the conduct of his office;  (ii) with
     respect to any matter as to which he shall  have been  finally  adjudicated
     not to have acted in good faith in the  reasonable  belief  that his action
     was in the best  interest  of the Trust or a Series  thereof;  (iii) in the
     event  of  a  settlement  or  other   disposition  not  involving  a  final
     adjudication  resulting in a payment by a Trustee or officer,  unless there
     has been a  determination  that such  Trustee or officer  did not engage in
     willful  misfeasance,  bad faith, gross negligence or reckless disregard of
     the duties  involved  in the  conduct of his office by (A) a court by (B) a
     majority of the Non- interested  trustees or independent legal counsel,  or
     (C) a vote of the majority of the Fund's outstanding shares.

     The rights of indemnification may be insured against by policies maintained
     by the Trust,  shall be  severable,  shall not  affect any other  rights to
     which any  Trustee or  officer  may now or  hereafter  be  entitled,  shall
     continue  as to a person who has ceased to be such  Trustee or officer  and
     shall  inure to the  benefit of the heirs,  executors,  administrators  and
     assigns of such a person.  Nothing contained herein shall affect any rights
     to  indemnification  to which  personnel of the Trust or any Series thereof
     other than  Trustees  and officers may be entitled by contract or otherwise
     under law.

     Expenses of preparation and presentation of a defense to any claim, action,
     suit or proceeding  may be advanced by the Trust or a Series thereof before
     final disposition, if the recipient undertakes to repay the amount if it is
     ultimately determined that he is not entitled to indemnification,  provided
     that either:

          (i)  such  undertaking  is  secured  by a  surety  bond or some  other
          appropriate security provided by the recipient, or the Trust or Series
          thereof  shall  be  insured  against  losses  arising  out of any such
          advances; or (ii) a majority of the Non-interested  Trustees acting on
          the matter  (provided that a majority of the  Non-interested  Trustees
          act on the  matter)  or an  independent  legal  counsel  in a  written
          opinion  shall  determine,  based upon a review of  readily  available
          facts (as opposed to a full trial-type inquiry),  that there is reason
          to believe that the  recipient  ultimately  will be found  entitled to
          indemnification.


                                      C-2

<PAGE>

          For purposes of indemnification Non-interested Trustee" is one who (i)
          is not an "Interested  Person" of the Trust (including  anyone who has
          been  exempted  from  being  an  "Interested   Person"  by  any  rule,
          regulation  or order of the  Commission),  and (ii) is not involved in
          the claim, action, suit or proceeding.

     (b) Under the Distribution Agreement.  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 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  to be
entitled to indemnification.

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

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


                                      C-3

<PAGE>

Insofar as indemnification for liabilities under the Securities Act of 1933 (the
"Act")  may be  permitted  to  Trustees,  officers  and  controlling  persons of
Registrant  pursuant  to the  Registrant's  Amended  and  Restated  Articles  of
Incorporation,  Article  10.1  of the  Registrant's  By-Laws,  The  underwriting
Agreement,  the By-Laws of John Hancock  Funds,  the Adviser,  or the  Insurance
Company or  otherwise,  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,  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.
