Overview

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

GOAL OF THE INCOME FUNDS

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

WHO MAY WANT TO INVEST

These funds may be appropriate for investors who:

o  are seeking a regular stream of income

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

o  want to diversify their portfolios

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

o  are retired or nearing retirement

Income funds may NOT be appropriate if you:

o  are investing for maximum return over a long time horizon

o  require absolute stability of your principal

THE MANAGEMENT FIRM

   
All John Hancock income funds are managed by John Hancock Advisers, Inc. Founded
in 1968, John Hancock Advisers is a wholly owned subsidiary of John Hancock
Mutual Life Insurance Company and manages more than $22 billion in assets.

Government Income Fund

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

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

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

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

RISK FACTORS
[Clip art] As with most income funds, the value of your investment will
fluctuate with changes in interest rates. Typically, a rise in interest rates
causes a decline in the market value of debt securities (including U.S.
Government and mortgage-backed securities). To the extent that the fund invests
in mortgage-backed securities, it may also be subject to extension and
prepayment risks. These risks are defined in "More about risk" starting on page
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
[Clip art] Barry H. Evans, CFA, leader of the fund's portfolio management team
since January 1995, is a senior vice president of the adviser. He has been in
the investment business since joining John Hancock Funds in 1986.

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

High Yield Bond Fund

REGISTRANT NAME: JOHN HANCOCK BOND TRUST
                               TICKER SYMBOL      CLASS A: JHHBX  CLASS B: TSHYX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY
[Clip art] The fund seeks to maximize current income without assuming undue
risk. To pursue this goal, the fund invests primarily in junk bonds, i.e.
lower-rated, higher-yielding debt securities.

Because the performance of junk bonds has historically been influenced by
economic conditions, the fund may rotate securities selection by business sector
according to the economic outlook.

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

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

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

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

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

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

Issuers of junk bonds are typically in weak financial health and their ability
to pay interest and principal is uncertain. Compared with issuers of
investment-grade bonds, they are more likely to encounter financial difficulties
and to be materially affected by these difficulties when they do encounter them.
Junk bond markets may react strongly to adverse news about an issuer or the
economy, or to the perception or expectation of adverse news. Before you invest,
please read "More about risk" starting on page 29.

PORTFOLIO MANAGEMENT

  Assuming no redemption            $18      $56      $97      $191
    

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

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

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

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

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

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

RISK FACTORS
[Clip art] As with most income funds, the value of your investment will
fluctuate with changes in interest rates. Typically, a rise in interest rates
causes a decline in the market value of debt securities (including U.S.
Government and mortgage-backed securities). To the extent that the fund invests
in mortgage-backed securities, it may also be subject to extension and
prepayment risks. These risks are defined in "More about risk" starting on page
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
[Clip art] Roger C. Hamilton, leader of the fund's portfolio management team
since January 1992 (with the fund's previous adviser), is a vice president of
the adviser. He joined John Hancock Funds in December 1994 and has been in the
investment business since 1980.

INVESTOR EXPENSES
[Clip art] Fund investors pay various expenses, either directly or indirectly.
The figures below show the expenses for the past year, adjusted to reflect any
changes. Future expenses may be greater or less.

Total fund operating expenses (after limitation)(3)   0.75%       1.50%

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

- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10

Class B shares
  Assuming redemption
  at end of period                  $45      $67      $82      $131
  Assuming no redemption            $15      $47      $82      $131

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)   Reflects the adviser's temporary agreement to limit expenses (except for
      12b-1 and other class-specific expenses). Without this limitation,
      management fees would be 0.40% for each class, other expenses would be
      1.27% for each class and total fund operating expenses would be 1.92% for
      Class A and 2.67% for Class B.

Limited-Term Government Fund

REGISTRANT NAME: JOHN HANCOCK LIMITED-TERM GOVERNMENT FUND
                                    TICKER SYMBOL CLASS A: JHNLX  CLASS B: JHLBX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY
[Clip art] 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 typically will have maturities of ten years or
less.

PORTFOLIO SECURITIES
[Clip art] Under normal circumstances, the fund invests at least 80% of assets
in securities that are issued, or guaranteed as to principal and interest, by
the U.S. Government, its agencies or instrumentalities. These may include
Treasuries and mortgage-backed securities such as Ginnie Maes and Fannie Maes.

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

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

- --------------------------------------------------------------------------------
INVESTOR EXPENSES
[Clip art] Fund investors pay various expenses, either directly or indirectly.
The figures below show the expenses for the past year, adjusted to reflect any

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

   
- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10

Class B shares
  Assuming redemption
  at end of period                  $51      $84      $110     $195
  Assuming no redemption            $21      $64      $110     $195
    

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

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

Sovereign Bond Fund

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

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

PORTFOLIO SECURITIES
[Clip art] Under normal circumstances, the fund invests at least 65% of assets
in corporate and government bonds and debentures. Typically, at least
three-quarters of these debt securities (excluding commercial paper) will be: 
o  securities of any type of issuer that are rated among the four highest
   Moody's or S&P rating categories and their unrated equivalents
o  U.S. Government and agency securities

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

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

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

These risks are defined in "More about risk" starting on page 29. The longer the
fund's average weighted maturity, the more it is likely to be affected by a
change in interest rates. Please read "More about risk" carefully before
investing.

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

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

Other expenses                                  0.31%       0.31%
Total fund operating expenses                   1.11%       1.81%
    

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

   
- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10
- --------------------------------------------------------------------------------
Class A shares                      $56      $78      $103     $173
Class B shares
  Assuming redemption
  at end of period                  $69      $87      $118     $194
  Assuming no redemption            $19      $57      $98      $194
    

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

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

Sovereign U.S. Government Income Fund

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

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

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

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

RISK FACTORS
[Clip art] As with most income investments, the value of your investment will
fluctuate with changes in interest rates. Typically, a rise in interest rates
causes a decline in the market value of debt securities (including U.S.
Government and mortgage-backed securities). To the extent that the fund invests
in mortgage-backed securities, it may also be subject to extension and
prepayment risks. These risks are defined in "More about risk" starting on page
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
[Clip art] Barry H. Evans, CFA, leader of the fund's portfolio management team
since January 1995, is a senior vice president of the adviser. He has been in
the investment business since joining John Hancock Funds in 1986.

- --------------------------------------------------------------------------------
INVESTOR EXPENSES
[Clip art] Fund investors pay various expenses, either directly or indirectly.
The figures below show the expenses for the past year, adjusted to reflect any
changes. Future expenses may be greater or less.

Other expenses                                  0.37%       0.37%
Total fund operating expenses                   1.17%       1.87%
    

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

   
- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10
- --------------------------------------------------------------------------------
Class A shares                      $56      $80      $106     $181
Class B shares
  Assuming redemption
  at end of period                  $69      $89      $121     $201
  Assuming no redemption            $19      $59      $101     $201
    

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

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

Strategic Income Fund

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

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

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

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

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

RISK FACTORS
[Clip art] Investors should expect fluctuations in share price, yield and total
return that are above-average for bond funds. Typically, a rise in interest
rates causes a decline in the market value of debt securities. The longer the
fund's average weighted maturity, the more it is likely to be affected by a
change in interest rates. To the extent that the fund invests in mortgage-backed
securities, it may also be subject to extension and prepayment risks. These
risks are defined in "More about risk" starting on page 29. Foreign securities
carry additional risks, including currency, information, natural event and
political risks. Issuers of junk bonds are typically in weak financial health,
and their ability to pay interest and principal is uncertain, especially in an
adverse economy. Junk bond markets may react strongly to adverse news about an
issuer or the economy, or to the perception or expectation of adverse news.
Please read "More about risk" carefully before investing.

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

- --------------------------------------------------------------------------------
INVESTOR EXPENSES
[Clip art] Fund investors pay various expenses, either directly or indirectly.

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

   
- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10

Class A shares                      $55      $75      $98      $162
Class B shares
  Assuming redemption
  at end of period                  $67      $84      $112     $182
  Assuming no redemption            $17      $54      $92      $182
    

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

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

CHOOSING A SHARE CLASS
All John Hancock income funds offer two classes of shares, Class A and Class B.
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.

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

      several ways to reduce these              for you right away.

                                                Class A shares.
o     Lower annual expenses than

                                                described below.

                                                years (Group 2) (see below),
                                                thus reducing future annual
                                                expenses.

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

- --------------------------------------------------------------------------------
CDSC on $1 million+ investments (Groups 1 and 2)
- --------------------------------------------------------------------------------
Your investment                     CDSC on shares being sold

First $1M - $4,999,999              1.00%
Next $1 - $5M above that            0.50%
Next $1 or more above that          0.25%

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

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

Class B Shares are offered at their net asset value per share, without any
initial sales charge. However, you may be charged a contingent deferred sales
charge (CDSC) on shares you sell within a certain time after you bought them, as
described in the table below. There is no CDSC on shares acquired through
reinvestment of dividends. The CDSC is based on the original purchase cost or
the current market value of the shares being sold, whichever is less. The longer
the time between the purchase and the sale of shares, the lower the rate of the
CDSC:

After 6 years           None                    None

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 of John Hancock funds to take advantage of
the breakpoints in the sales charge schedule. The first three ways can be
combined in any manner.

o     Accumulation Privilege -- lets you add the value of any Class A shares you
      already own to the amount of your next Class A investment for purposes of
      calculating the sales charge.
o     Letter of Intention -- lets you purchase Class A shares of a fund over a
      13-month period and receive the same sales charge as if all shares had
      been purchased at once.
o     Combination Privilege -- lets you combine Class A shares of multiple funds
      for purposes of calculating the sales charge.

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

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

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

CDSC waivers As long as Signature Services is notified at the time you sell, the
CDSC for either share class will generally be waived in the following cases:
o  to make payments through certain systematic withdrawal plans
o  to make certain distributions from a retirement plan
o  because of shareholder death or disability

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

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

To utilize: contact your financial representative or Signature Services.


                                                                YOUR ACCOUNT  19

      John Hancock funds
o     individuals transferring assets to a John Hancock fund from an employee
      benefit plan that has John Hancock funds
o     members of an approved affinity group financial
      services program
o     certain insurance company contract holders (one-year CDSC usually applies)
o     participants in certain retirement plans with at least 100 members
      (one-year CDSC applies)
   
o     current shareholders of Limited-Term Government Fund making additional
      investments in the fund with the proceeds from any non-John Hancock mutual
      fund, as long as that fund had sales charges and the investor paid them;
      investors must supply a copy of the redemption check or confirmation
      statement, and must remain invested in Limited-Term Government Fund for at
      least 15 days
    

To utilize: if you think you may be eligible for a sales charge waiver, contact
Signature Services or consult the SAI.

request to sell shares in writing. You may need to include additional items with
your request, as shown in the table below. You may also need to include a
signature guarantee, which protects you against fraudulent orders. You will need
a signature guarantee if:
o     your address of record has changed within the past 30 days
o     you are selling more than $100,000 worth of shares
o     you are requesting payment other than by a check mailed to the address of
      record and payable to the registered owner(s)

You can generally obtain a signature guarantee from the following sources:
o     a broker or securities dealer
o     a federal savings, cooperative or other type of bank
o     a savings and loan or other thrift institution
o     a credit union

TRANSACTION POLICIES

Valuation of shares The net asset value per share (NAV) for each fund and class
is determined each business day at the close of regular trading on the New York
Stock Exchange (typically 4 P.M. Eastern Time) by dividing a class's net assets
by the number of its shares outstanding.

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

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

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

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

Telephone transactions For your protection, telephone requests may be recorded
in order to verify their accuracy. In addition, Signature Services will take
measures to verify the identity of the caller, such as asking for name, account
number, Social Security or other taxpayer ID number and other relevant
information. If appropriate measures are taken, Signature Services is not
responsible for any losses that may occur to any account due to an unauthorized
telephone call. Also for your protection, telephone transactions are not
permitted on accounts whose names or addresses have changed within the past 30
days. Proceeds from telephone transactions can only be mailed to the address of
record.

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

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

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

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

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

Account statements  In general, you will receive account statements as follows:
o     after every transaction (except a dividend reinvestment) that affects your
      account balance
o     after any changes of name or address of the registered owner(s)
o     in all other circumstances, every quarter

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

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

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


24  YOUR ACCOUNT
<PAGE>

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

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

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

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

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

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

Monthly Automatic Accumulation Program (MAAP) MAAP lets you set up regular
investments from your paycheck or bank account to the John Hancock fund(s) of
your choice. You determine the frequency and amount of your investments, and you
can terminate your program at any time. To establish:
o     Complete the appropriate parts of your account application.
o     If you are using MAAP to open an account, make out a check ($25 minimum)
      for your first investment amount payable to "John Hancock Signature
      Services, Inc." Deliver your check and application to your financial
      representative or Signature Services.

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

   
Retirement plans John Hancock Funds offers a range of qualified retirement
plans, including IRAs, SIMPLE plans, SEPs, 401(k) plans, 403(b) plans (including
TSAs) and other pension and profit-sharing plans. Using these plans, you can
invest in any John Hancock fund (except tax-free income funds) with a low
minimum investment of $250 or, for some group plans, no minimum investment at
all. To find out more, call Signature Services at 1-800-225-5291.

BUSINESS STRUCTURE

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

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

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

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

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

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

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

Diversification All of the income funds are diversified.

- --------------------------------------------------------------------------------
SALES COMPENSATION

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

Compensation payments originate from two sources: from sales charges and from
12b-1 fees that are paid out of the funds' assets ("12b-1" refers to the federal
securities regulation that authorizes annual fees of this type). The 12b-1 fee
rates vary by fund and by share class, according to Rule 12b-1 plans adopted by
the funds. The sales charges and 12b-1 fees paid by investors are detailed in
the fund-by-fund information. The portions of these expenses that are reallowed
to financial services firms are shown on the next page.

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

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

Initial compensation Whenever you make an investment in a fund or funds, the
financial services firm receives either a reallowance from the initial sales
charge or a commission, as described below. The firm also receives the first
year's service fee at this time.

Annual compensation Beginning with the second year after an investment is made,
the financial services firm receives an annual service fee of 0.25% of its total
eligible net assets. This fee is paid quarterly in arrears.

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

MORE ABOUT RISK

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

The funds are permitted to utilize -- within limits established by the trustees
- -- certain other securities and investment practices that have higher risks and
opportunities associated with them. To the extent that a fund utilizes these
securities or practices, its overall performance may be affected, either
positively or negatively. On the following pages are brief descriptions of these
securities and investment practices, along with the risks associated with them.
The funds follow certain policies that may reduce these risks.

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

- --------------------------------------------------------------------------------
TYPES OF INVESTMENT RISK

Correlation risk The risk that changes in the value of a hedging instrument will
not match those of the asset being hedged (hedging is the use of one investment
to offset the effects of another investment). Incomplete correlation can result
in unanticipated risks.

Credit risk The risk that the issuer of a security, or the counterparty to a
contract, will default or otherwise become unable to honor a financial
obligation.

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

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

Interest rate risk The risk of market losses attributable to changes in interest
rates. With fixed-rate securities, a rise in interest rates typically causes a
fall in values, while a fall in rates typically causes a rise in values.

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

o     Hedged When a derivative (a security whose value is based on another
      security or index) is used as a hedge against an opposite position that
      the fund also holds, any loss generated by the derivative should be
      substantially offset by gains on the hedged investment, and vice versa.
      While hedging can reduce or eliminate losses, it can also reduce or
      eliminate gains.
o     Speculative To the extent that a derivative is not used as a hedge, the
      fund is directly exposed to the risks of that derivative. Gains or losses
      from speculative positions in a derivative may be substantially greater
      than the derivative's original cost.

   
Liquidity risk The risk that certain securities may be difficult or impossible
to sell at the time and the price that the seller would like. The seller may
have to lower the price, sell other securities instead, or forego an investment
opportunity, any of which could have a negative effect on fund management or
performance.
    

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

Market risk The risk that the market value of a security may move up and down,
sometimes rapidly and unpredictably. Market risk may affect a single issuer, an
industry, a sector of the bond market or the market as a whole. Common to all
stocks and bonds and the mutual funds that invest in them.

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

Opportunity risk The risk of missing out on an investment opportunity because
the assets necessary to take advantage of it are tied up in less advantageous
investments.

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

Prepayment risk The risk that unanticipated prepayments may occur, reducing the
value of mortgage-backed securities.

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

ORGANIZATION OF THE FUND

The Fund is a diversified open-end investment  management company organized as a
Massachusetts   business   trust   under  the  laws  of  The   Commonwealth   of
Massachusetts. The Fund was organized in 1984.

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

INVESTMENT OBJECTIVE AND POLICIES

The following  information  supplements the discussion of the Fund's  investment
objective and policies discussed in the Prospectus.

   
The Fund's  investment  objective is to generate a high level of current income,
consistent with prudent  investment  risk,  through  investment in a diversified
portfolio of freely  marketable debt securities.  The Adviser seeks high current
income  consistent  with the moderate level of risk  associated with a portfolio
consisting primarily of investment grade debt securities.
    

Under normal conditions,  at least 65% of the value of the Fund's assets will be
in bonds and/or debentures.  In addition,  the Fund contemplates at least 75% of
the value of its total  investments in debt  securities  (other than  commercial
paper)  will be  represented  by  those  securities  that  have,  at the time of
purchase,  a rating  within the four  highest  grades as  determined  by Moody's
Investors  Service,  Inc.  ("Moody's")  (Aaa, Aa, A or Baa) or Standard & Poor's
("S&P") (AAA, AA, A, or BBB) and debt securities of banks,  the U.S.  Government
and its agencies or  instrumentalities  and other  issuers  which,  although not
rated as a matter of policy by either Moody's or S&P, are considered by the Fund
to have investment quality comparable to securities receiving ratings within the
four  highest  grades.   Debt  securities   rated  Baa  or  BBB  are  considered
medium-grade  obligations with speculative  characteristics and adverse economic
conditions  or changing  circumstances  may weaken the issuers'  capacity to pay
interest  and repay  principal.  The Fund will,  when  feasible,  purchase  debt
securities which are non-callable. The Fund will diversify its investments among
a number of industry groups without  concentration  in any particular  industry.
The Fund's investments, and consequently its net asset value, 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.

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.

For liquidity and  flexibility,  the Fund may place up to 35% of total assets in
investment-grade  short-term securities.  In abnormal market conditions,  it may
invest more assets in these securities as a defensive  tactic.  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

                                       2

<PAGE>

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.

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

   
Subsequent to its purchase by the Fund,  an issue of securities  may cease to be
rated or its rating may be reduced  below the minimum  required  for purchase by
the Fund. Neither of these events will require the sale of the securities by the
Fund,  but the Adviser will consider the event in its  determination  of whether
the Fund should continue to hold the securities.

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

Structured  Securities.  The Fund may invest in structured  securities including
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.
    

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,
or below BBB by 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.

                                       3

<PAGE>

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
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.

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  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

                                       4

<PAGE>

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."

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

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

Reverse  Repurchase  Agreements.  The Fund may also enter into reverse  purchase
agreements  which  involve the sale of U.S.  Government  securities  held in its
portfolio to a bank with an agreement that the Fund will buy back the securities
at a fixed  future  date at a fixed  price plus an agreed  amount of  "interest"
which may be reflected in the repurchase price.  Reverse  repurchase  agreements
are  considered  to be  borrowings by the Fund.  Reverse  repurchase  agreements
involve the risk that the market value of securities  purchased by the Fund with
proceeds  of the  transaction  may  decline  below the  repurchase  price of the
securities  sold by the Fund which it is obligated to repurchase.  The Fund will
also  continue to be subject to the risk of a decline in the market value of the
securities sold under the agreements  because it will reacquire those securities
upon effecting  their  repurchase.  To minimize  various risks  associated  with
reverse  repurchase  agreements,  the Fund will  establish and maintain with the
Fund's custodian a separate account consisting of liquid securities, of any type
or  maturity,  in an  amount  at least  equal to the  repurchase  prices  of the
securities  (plus any  accrued  interest  thereon)  under  such  agreements.  In
addition,  the Fund will not enter into reverse repurchase  agreements or 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

                                       5

<PAGE>

outstanding borrowings exceed 5% of the Fund's total assets. The Fund will enter
into reverse  repurchase  agreements only with federally insured banks which are
approved in advance as being creditworthy by the Trustees.  Under the procedures
established by the of Trustees, the Adviser will monitor the creditworthiness of
the banks involved.

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

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

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

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

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

                                       6

<PAGE>

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

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

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

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

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

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

                                       7

<PAGE>

issued  by the  Options  Clearing  Corporation  as a result  of  trades  on that
exchange would continue to be exercisable in accordance with their terms.

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

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

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

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

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

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

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

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

                                       8

<PAGE>

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

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

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

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

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

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

Other  Considerations.  The Fund will  engage in  futures  and  related  options
transactions  either for bona fide hedging purposes or to seek to increase total
return as  permitted by the CFTC.  To the extent that the Fund is using  futures
and related  options for hedging  purposes,  futures  contracts  will be sold to
protect  against a  decline  in the  price of  securities  that the Fund owns or
futures  contracts  will be purchased to protect the Fund against an increase in
the price of securities it intends to purchase. The Fund will determine that the
price  fluctuations  in the futures  contracts  and options on futures  used for
hedging purposes are substantially  related to price  fluctuations in securities
held by the Fund or securities or instruments  which it expects to purchase.  As
evidence  of its hedging  intent,  the Fund  expects  that on 75% or more of the
occasions on which it takes a long  futures or option  position  (involving  the
purchase of futures contracts),  the Fund will have purchased, or will be in the
process of  purchasing,  equivalent  amounts of related  securities  in the cash
market at the time when the futures or option  position is closed out.  However,
in particular cases, when it is economically advantageous for the Fund to do so,

                                       9

<PAGE>

a long futures  position may be terminated  or an option may expire  without the
corresponding purchase of securities or other assets.

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

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

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

Perfect correlation between the Fund's futures positions and portfolio positions
will be  impossible  to  achieve.  There are no  futures  contracts  based  upon
individual  securities,  except  certain U.S.  Government  securities.  The only
futures contracts available to hedge the Fund's portfolio are various futures on
U.S. Government  securities and securities indices. In the event of an imperfect
correlation  between  a  futures  position  and a  portfolio  position  which is
intended to be  protected,  the desired  protection  may not be obtained and the
Fund may be exposed to risk of loss.

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

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

When the Fund engages in forward  commitment and  when-issued  transactions,  it
relies on the seller to consummate the transaction. The failure of the issuer or
seller to  consummate  the  transaction  may  result in the  Fund's  losing  the
opportunity  to obtain a price  and yield  considered  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.


                                       10
<PAGE>

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

Mortgage  "Dollar Roll"  Transactions.  The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers  pursuant to which the
Fund sells mortgage-backed securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date.  The Fund will only enter into covered rolls. A "covered roll" is a
specific type of dollar roll for which there is an offsetting cash position or a
cash  equivalent  security  position  which  matures  on or before  the  forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior  security and will be excluded from the  calculation
of the Fund's 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. Asset-backed securities are often subject to more rapid
repayment  than their  stated  maturity  date would  indicate as a result of the
pass-through of prepayments of principal on the underlying loans. During periods
of  declining  interest  rates,  prepayment  of  loans  underlying  asset-backed
securities  can be expected to  accelerate.  Accordingly,  the Fund's ability to
maintain  positions in these  securities  will be affected by  reductions in the
principal amount of such securities resulting from prepayments,  and its ability
to  reinvest  the  returns  of  principal  at  comparable  yields is  subject to
generally prevailing interest rates at that time.
    

Credit  card  receivables  are  generally  unsecured  and  the  debtors  on such
receivables  are  entitled  to the  protection  of a number of state and federal
consumer  credit  laws,  many of which  give such  debtors  the right to set-off
certain  amounts  owed on the credit  cards,  thereby  reducing the balance due.
Automobile  receivables  generally are secured,  but by automobiles  rather than
residential  real property.  Most issuers of automobile  receivables  permit the
loan  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.

   
Swaps,  Caps,  Floors  and  Collars.  As one way of  managing  its  exposure  to
different  types of  investments,  the Fund may enter into  interest rate swaps,
currency swaps,  and other types of swap  agreements  such as caps,  collars and
floors.  In a typical  interest  rate  swap,  one party  agrees to make  regular
payments equal to a floating interest rate times a "notional  principal amount,"
in return  for  payments  equal to a fixed  rate  times the same  amount,  for a
specified period of time. If a swap agreement  provides for payment in different
currencies, the parties might agree to exchange the notional principal amount as
well.  Swaps may also depend on other  prices or rates,  such as the value of an
index or mortgage prepayment rates.
    
                                       11

<PAGE>

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

Swap agreements will tend to shift the Fund's investment  exposure from one type
of investment to another.  For example,  if the Fund agreed to exchange payments
in dollars for payments in a foreign currency,  the swap agreement would tend to
decrease the Fund's exposure to U.S. interest rates and increase its exposure to
foreign  currency and interest rates.  Caps and floors have an effect similar to
buying or writing  options.  Depending on how they are used, swap agreements may
increase or decrease  the overall  volatility  of a Fund's  investments  and its
share price and yield.

Swap agreements are sophisticated  hedging  instruments that typically involve a
small  investment  of cash  relative to the  magnitude  of risks  assumed.  As a
result,  swaps can be highly volatile and may have a considerable  impact on the
Fund's  performance.  Swap  agreements  are  subject  to  risks  related  to the
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.

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

   
Brady  Bonds.  The Fund may  invest  in Brady  Bonds and  other  sovereign  debt
securities  of  countries  that  have  restructured  or are in  the  process  of
restructuring  sovereign  debt pursuant to the Brady Plan.  Brady Bonds are debt
securities  described as part of a restructuring  plan created by U.S.  Treasury
Secretary  Nicholas  F.  Brady in 1989 as a  mechanism  for  debtor  nations  to
restructure their outstanding external indebtedness (generally,  commercial bank
debt).  In  restructuring  its external debt under the Brady Plan  framework,  a
debtor nation  negotiates with its existing bank lenders as well as multilateral
institutions  such as the World Bank and the  International  Monetary  Fund (the
"IMF").  The Brady Plan  facilitates  the exchange of  commercial  bank debt for
newly issued bonds  (known as Brady  Bonds).  The World Bank and the IMF provide
funds pursuant to loan agreements or other  arrangements which enable the debtor
nation to  collateralize  the new Brady Bonds or to repurchase  outstanding bank
debt at a discount. Under these arrangements the IMF debtor nations are required
to implement  domestic monetary and fiscal reforms.  These reforms have included
the  liberalization  of trade  and  foreign  investment,  the  privatization  of
state-owned  enterprises  and the  setting of targets  for public  spending  and
borrowing.  These  policies  and programs  seek to promote the debtor  country's

                                       12

<PAGE>

ability to service its external  obligations and promote its economic growth and
development.  The Brady  Plan only sets forth  general  guiding  principles  for
economic  reform  and  debt  reduction,   emphasizing  that  solutions  must  be
negotiated on a case-by-case  basis between debtor nations and their  creditors.
The Adviser believes that economic reforms undertaken by countries in connection
with the issuance of Brady Bonds make the debt of countries which have issued or
have  announced  plans  to  issue  Brady  Bonds an  attractive  opportunity  for
investment.
    

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

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

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

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

                                       13

<PAGE>

income  securities in order to realize  capital gains or improve  income.  Short
term trading may have the effect of increasing  portfolio  turnover rate. A high
rate of portfolio  turnover (100% or greater) involves  correspondingly  greater
brokerage  expenses and may make it more  difficult for the Fund to qualify as a
regulated  investment  company  for  federal  income  tax  purposes.  The Fund's
portfolio  turnover rate is set forth in the table under the caption  "Financial
Highlights" in the Prospectus.

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 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.

INVESTMENT RESTRICTIONS

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

The Fund may not:

         (1) 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

                                       14

<PAGE>

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 1933 Act.
    
         (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 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.

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


                                       15

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

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

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

If a percentage  restriction 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.

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

INVESTMENT ADVISORY AND OTHER SERVICES

   
The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts 02199-7603,
was  organized in 1968 and has more than $22 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 more than $100
billion,  the Life Company is one of the ten largest life insurance companies in
the United  States,  and carries a high rating from  Standard & Poor's and A. M.
Best's.  Founded in 1862, the Life Company has been serving clients for over 130
years

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

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

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

                  Net Asset Value                           Annual Rate
                  ---------------                           -----------
                  First $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.

                                       25

<PAGE>

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.

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

Pursuant to the Advisory  Agreement,  the Adviser is not liable for any error of
judgment or mistake of law or for any loss  suffered  by the Fund in  connection
with the matters to which its 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 of the obligations and
duties under the contract.

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

   
For the fiscal  years  ended  December  31,  1994,  1995 and 1996,  the  Adviser
received fees of $7,116,092,  $7,406,635 and $7,799,825,  respectively.  For the
period  from  January 1, 1997 to May 31,  1997,  the  Adviser  received  fees of
$3,116,997.

Accounting and Legal Services Agreement.  The Trust, on behalf of the Fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this agreement,  the Adviser  provides the Fund with certain tax,  accounting
and legal  services.  For the fiscal year ended December 31, 1996, the Fund paid
the Adviser  $291,977 for  services  under this  agreement.  For the period from
January 1, 1997 to May 31, 1997, the Fund paid the Adviser $116,998 for services
under this agreement.
    

In order to avoid conflicts with portfolio  trades for the Fund, the Adviser and
the Fund have adopted extensive  restrictions on personal  securities trading by
personnel of the Adviser and its  affiliates.  Some of these  restrictions  are:
pre-clearance  for all  personal  trades  and a ban on the  purchase  of initial
public offerings,  as well as contributions to specified charities of profits on

                                       26

securities held for less than 91 days. These  restrictions are a continuation of
the basic  principle  that the interests of the Fund and its  shareholders  come
first.

DISTRIBUTION CONTRACTS

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

Total  underwriting  commissions  for sales of the Fund's Class A shares for the
fiscal years ended December 31, 1995 and 1996 were  $2,063,924  and  $2,391,266,
respectively,  and for the  period  from  January  1,  1997 to May 31,  1997 was
$695,419. Of such amounts $215,658,  $247,763, and $80,489,  respectively,  were
retained by John Hancock Funds in 1995,  1996 and for the period from January 1,
1997 to May  31,  1997.  The  remainder  of the  underwriting  commissions  were
reallowed to dealers.

The Fund's Trustees adopted Distribution Plans with respect to Class A and Class
B shares (the "Plans")  pursuant to Rule 12b-1 under the Investment  Company Act
of 1940 (the  "Investment  Company  Act").  Under the  Plans,  the Fund will pay
distribution  and service  fees at an  aggregate  annual rate of up to 0.30% and
1.00%,  respectively,  of the Fund's  average daily net assets  attributable  to
shares of that class.  However,  the  service  fee will not exceed  0.25% of the
Fund's  average  daily net assets  attributable  to each  class of  shares.  The
distribution  fees  will be used to  reimburse  the John  Hancock  Funds for its
distribution  expenses,  including  but not  limited to: (i) initial and ongoing
sales  compensation to Selling Brokers and others  (including  affiliates of the
John  Hancock  Funds)  engaged  in the  sale of  Fund  shares;  (ii)  marketing,
promotional and overhead  expenses  incurred in connection with the distribution
of Fund shares; and (iii) with respect to Class B shares only, interest expenses
on  unreimbursed  distribution  expenses.  The  service  fees  will  be  used to
compensate  Selling  Brokers  and  others for  providing  personal  and  account
maintenance  services to  shareholders.  In the event that John Hancock Funds is
not fully reimbursed for payments or expenses they incur under the Class A Plan,
these  expenses will not be carried beyond twelve months from the date they were
incurred.  Unreimbursed  expenses under the Class B Plan will be carried forward
together with interest on the balance of these unreimbursed  expenses.  The Fund
does not treat the  unreimbursed  expenses under the Class B Plan as a liability
of the Fund because the Trustees may terminate the Class B Plan at any time. For
the period from January 1, 1997 to May 31, 1997,  an aggregate of  $3,987,089 of
distribution expenses or 3.0% of the average net assets of the Class B shares of
the Fund,  was not  reimbursed  or recovered by John Hancock  Funds  through the
receipt of deferred sales charges or Rule 12b-1 fees in prior periods.
    

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

                                       27

<PAGE>

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

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

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

   
During  the period  from  January  1, 1997 to May 31,  1997,  the Fund paid John
Hancock  Funds the  following  amounts  of  expenses  in  connection  with their
services for the Fund:

NET ASSET VALUE

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

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

                                       28

<PAGE>

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

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

The NAV of each fund and class is  determined  each business day at the close of
regular  trading on the New York Stock  Exchange  (typically  4:00 p.m.  Eastern
Time) by dividing a class's net assets by the number of its shares  outstanding.
On any day an international  market is closed and the New York Stock Exchange is
open,  any foreign  securities  will be valued at the prior day's close with the
current day's  exchange  rate.  Trading of foreign  securities may take place on
Saturdays and U.S.  business  holidays on which 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

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

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

Without Sales Charges.  Class A shares may be offered  without a front-end sales
charge or CDSC to various individuals and institutions as follows:

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

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.*

                                       29

<PAGE>

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

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

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

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

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

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

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

         Amount Invested                                  CDSC RATE
         ---------------                                  ---------

         $1 to $4,999,000                                   1.00%
         Next $5 million to $9,999,999                      0.50%
         Amounts of $10 million and over                    0.25%

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

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

Combination  Privilege.  In calculating the sales charge applicable to purchases
of Class A shares  made at one time,  the  purchases  will be combined to reduce
sales charges if made by (a) an individual, his or her spouse and their children
under the age of 21, purchasing  securities for his or their own account,  (b) a
trustee or other  fiduciary  purchasing for a single trust,  estate or fiduciary
account and (c) groups  which  qualify  for the Group  Investment  Program  (see
below).   Further  information  about  combined  purchases,   including  certain
restrictions on combined group purchases,  is available from Signature  Services
or a Selling Broker's representative.

                                       30

<PAGE>

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

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

Letter of Intention.  Reduced sales charges are also  applicable to  investments
made  pursuant  to a Letter  of  Intention  (the  "LOI"),  which  should be read
carefully  prior to its  execution by an  investor.  The Fund offers two options
regarding  the  specified  period  for  making  investments  under the LOI.  All
investors have the option of making their investments over a specified period of
thirteen (13) months. Investors who are using the Fund as a funding medium for a
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 IRAs, SEP, SARSEP,  401(k), 403(b) (including TSAs) and
Section 457 plans. Such an investment (including accumulations and combinations)
must aggregate  $100,000 or more invested  during the specified  period from the
date of the LOI or from a date  within  ninety  (90) days  prior  thereto,  upon
written  request to  Signature  Services.  The sales  charge  applicable  to all
amounts  invested under the LOI is computed as if the aggregate  amount intended
to be invested had been invested  immediately.  If such aggregate  amount is not
actually  invested,  the  difference  in the sales charge  actually paid and the
sales  charge  payable had the LOI not been in effect is due from the  investor.
However,  for the purchases actually made within the specified period (either 13
or 48 months)  the sales  charge  applicable  will not be higher than that which
would have applied  (including  accumulations and combinations) had the LOI been
for the amount actually invested.

The LOI  authorizes  Signature  Services  to hold in escrow  sufficient  Class A
shares  (approximately  5% of the  aggregate) to make up any difference in sales
charges on the amount intended to be invested and the amount actually  invested,
until such investment is completed  within the specified  period,  at which time
the escrow Class A shares will be released. If the total investment specified in
the LOI is not completed,  the Class A shares held in escrow may be redeemed and
the proceeds used as required to pay such sales charge as may be due. By signing
the  LOI,  the  investor  authorizes  Signature  Services  to  act as his 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 the Fund will  receive the full
amount of the purchase payment.

Contingent  Deferred Sales Charge.  Class B shares which are redeemed within six
years of purchase will be subject to a contingent deferred sales charge ("CDSC")
at the rates set forth in the  Prospectus  as a percentage  of the dollar amount
subject  to the CDSC.  The charge  will be  assessed  on an amount  equal to the
lesser of the current market value or the original  purchase cost of the Class B
shares being  redeemed.  No CDSC will be imposed on  increases in account  value
above  the  initial  purchase  prices,  including  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.

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

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

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

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

                                       32

<PAGE>

distribution-related  services  to the Fund in  connection  with the sale of the
Class B shares,  such as the payment of  compensation  to select Selling Brokers
for selling Class B shares. The combination of the CDSC and the distribution and
service  fees  facilitates  the  ability  of the Fund to sell the Class B shares
without a sales charge being deducted at the time of the purchase.

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

For all account types:

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

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

*        Redemptions due to death or disability.

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

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

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

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

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

*        Returns of excess contributions made to these plans.

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

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

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

SPECIAL REDEMPTIONS

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

ADDITIONAL SERVICES AND PROGRAMS

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

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

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

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

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

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

Systematic  Withdrawal Plan. The Fund permits the  establishment of a Systematic
Withdrawal  Plan.  Payments under this plan represent  proceeds arising from the
redemption of Fund shares.  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  realization of gain or loss for purposes of
Federal,  state  and  local  income  taxes.  The  maintenance  of  a  Systematic
Withdrawal  Plan  concurrently  with purchases of additional  Class A or Class B
shares of the Fund  could be  disadvantageous  to a  shareholder  because of the
initial  sales charge  payable on such  purchases of Class A shares and the CDSC
imposed on  redemptions  of Class B shares and because  redemptions  are taxable

                                       35

<PAGE>

events.  Therefore, a shareholder should not purchase Class A and Class B shares
at the same time a Systematic  Withdrawal  Plan is in effect.  The Fund reserves
the  right to  modify  or  discontinue  the  Systematic  Withdrawal  Plan of any
shareholder  on 30  days'  prior  written  notice  to  such  shareholder,  or to
discontinue  the  availability  of such plan in the future.  The shareholder may
terminate the plan at any time by giving proper notice to Signature Services.

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

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

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

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

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

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

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

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

   
Retirement plans participating in Merrill Lynch's servicing programs:

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

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

DESCRIPTION OF THE FUND'S SHARES

   
The Trustees of the Trust are  responsible for the management and supervision of
the Fund.  The  Declaration  of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of the Fund, without
par value.  Under the  Declaration of Trust,  the Trustees have the authority to
create and classify shares of beneficial  interest in separate  series,  without
further action by  shareholders.  As of the date of this Statement of Additional
Information, the Trustees have 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 new series of the Trust,  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.
    

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

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

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

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

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

                                       37

<PAGE>

limited to  circumstances  in which the Fund itself  would be unable to meet its
obligations, and the possibility of this occurrence is remote.

   
The Fund reserves the right to reject any  application  which conflicts with the
Fund's  internal  policies or the policies of any regulatory  authority.  Use of
information  provided  on the  account  application  may be used by the  Fund to
verify the accuracy of the  information or for  background or financial  history
purposes.  A joint account will be administered as a joint tenancy with right of
survivorship,  unless the joint owners notify Signature  Services of a different
intent.  A shareholder's  account is governed by the laws of The Commonwealth of
Massachusetts.
    

TAX STATUS

   
The Fund has qualified and has elected to be treated as a "regulated  investment
company"  under  Subchapter M of the Internal  Revenue Code of 1986,  as amended
(the  "Code"),  and intends to 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.
    

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 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.)  As a result of federal  tax  legislation  enacted on August 5, 1997,
gain recognized after May 6, 1997 from the sale of a capital asset is taxable to
individual  (noncorporate)  investors at different  maximum  federal  income tax
rates,  depending  generally  upon the tax  holding  period for the  asset,  the
federal income tax bracket of the taxpayer, and the dates the asset was acquired
and/or  sold.  The  Treasury  Department  may issue  regulations  to apply  this
legislation to the Fund's  distributions from its realized net capital gain, the
treatment  of which is  uncertain  prior to the  issuance of these  regulations.
Shareholders should contact their own tax advisers on the correct application of
these new rules.  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

                                       38

<PAGE>

transactions. At the time of an investor's purchase of Fund shares, a portion of
the purchase price is often attributable to realized or unrealized  appreciation
in the Fund's portfolio. Consequently,  subsequent distributions on these shares
from such  appreciation  may be taxable to such  investor  even if the net asset
value of the  investor's  shares is, as a result of the  distributions,  reduced
below the  investor's  cost for such shares,  and the  distributions  in reality
represent a return of a portion of the purchase price.

   
Upon a  redemption  or other  disposition  of shares of the Fund  (including  by
exercise of the exchange  privilege) in a transaction  that is treated as a sale
for tax purposes,  a shareholder will ordinarily  realize a taxable gain or loss
depending  upon the  amount  of the  proceeds  and the  investor's  basis in his
shares.  Such gain or loss will be treated as capital gain or loss if the shares
are capital assets in the shareholder's hands. A sales charge paid in purchasing
Class A shares  of the Fund  cannot  be  taken  into  account  for  purposes  of
determining  gain or loss on the  redemption  or exchange of such shares  within
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.  Shareholders should consult their own tax advisers
regarding their particular  circumstances to determine  whether a disposition of
Fund shares is properly treated as a sale for tax purposes, as is assumed in the
foregoing discussion.  Also, future Treasury Department  regulations that affect
the taxation of capital  gains may contain rules for  determining  different tax
rates  applicable to sales of Fund shares held for more than one year, more than
18 months,  and (for  certain  sales  after the year 2000 or the year 2005) more
than five years. These regulations may also contain other rules coordinating the
provisions  affecting the taxation of gains  recognized by funds on the sales of
their portfolio assets and the gains  recognized by the funds'  shareholders who
receive  distributions  attributable  to these gains and who redeem or otherwise
dispose of their shares in funds. These new regulations could modify some of the
provisions described above.
    

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

                                       39

<PAGE>

to the Fund and, as noted above,  would not be distributed to shareholders.  The
Fund has  $29,796,705  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 1999 through 2005.
    

Dividends and capital gain  distributions from the Fund will not qualify for the
dividends-received deduction for corporations.

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 gain,  to
qualify as a regulated  investment  company and avoid  liability for any federal
income or excise tax.  Therefore,  the Fund may have to dispose of its portfolio
securities under disadvantageous circumstances to generate cash, or borrow cash,
to satisfy these distribution requirements.

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

The Fund will be required to report to the Internal  Revenue Service (the "IRS")
all taxable  distributions to  shareholders,  as well as gross proceeds from the
redemption  or exchange  of Fund  shares,  except in the case of certain  exempt
recipients,  i.e.,  corporations  and certain other investors  distributions  to
which are exempt from the information  reporting  provisions of the Code.  Under
the backup withholding  provisions of Code Section 3406 and applicable  Treasury
regulations,  all such reportable  distributions  and proceeds may be subject to
backup  withholding  of  federal  income  tax at the  rate of 31% in the case of
non-exempt shareholders who fail to furnish the Fund with their correct taxpayer
identification number and certain  certifications  required by the IRS or if the
IRS or a broker  notifies the Fund that the number  furnished by the shareholder
is  incorrect  or that the  shareholder  is subject to backup  withholding  as a
result of 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,

                                       40

<PAGE>

whether taken in cash or  reinvested  in shares,  will be reduced by the amounts
required  to be  withheld.  Any  amounts  withheld  may be  credited  against  a
shareholder's U.S. federal income tax liability.  Investors should consult their
tax advisers about the applicability of the backup withholding provisions.

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

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
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

                                       41

<PAGE>

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  ending May 31,  1997,  the yield on Class A and Class B
shares of the Fund was 6.26% and 5.85%,  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 May 31, 1997 was 4.16%, 6.84% and 8.37%, respectively.

The  average  total  return  of Class B shares of the Fund for the  period  from
January 1, 1997 to May 31, 1997 and since  inception  on  November  23, 1993 was
3.31% and 5.17%, respectively.
    

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

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

         a =   dividends and interest earned during the period.

         b =   net expenses accrued during the period.

         c =   the average daily number of fund shares outstanding during
               the period that would be entitled to receive dividends.

         d =   the maximum offering price per share on the last day of the 
               period (NAV where applicable).

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.

                                       42

<PAGE>

         n =      number of years.

         ERV =    ending redeemable value of hypothetical $1,000 investment made
                  at the beginning of the 1 year, 5 year and 10 year periods.

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

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

From time to time,  in reports  and  promotional  literature,  the Fund's  total
return  and/or  yield will be 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 of the Adviser,  which consists
of officers and  directors of the Adviser and  affiliates,  and Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner  which,  in the opinion of the  Adviser,  will offer the best
price and market for the  execution  of each such  transaction.  Purchases  from
underwriters  of portfolio  securities  may include a commission or  commissions
paid by the issuer  and  transactions  with  dealers  serving  as market  makers
reflect a "spread." Debt securities are generally  traded on a net basis through
dealers  acting  for their own  account as  principals  and not as  brokers;  no
brokerage commissions are payable on such transactions.

                                       43

<PAGE>

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

The Fund's  primary  policy is to execute all  purchases  and sales of portfolio
instruments  at the  most  favorable  prices  consistent  with  best  execution,
considering all of the costs of the transaction including brokerage commissions.
This policy governs the selection of brokers and dealers and the market in which
a transaction is executed.  Consistent with the foregoing  primary  policy,  the
Rules of Fair Practice of the National  Association of Securities Dealers,  Inc.
and other policies 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's officers will be primarily responsible for
the  allocation of the Fund's  brokerage  business,  the policies in this regard
must be consistent with the foregoing and will at all times be subject to review
by the  Trustees.  For the  fiscal  years  ended  December  31,  1996 and  1995,
negotiated brokerage commission were $65,835 and $0, respectively,  on portfolio
transactions.  For the  fiscal  period  from  January  1, 1997 to May 31,  1997,
negotiated brokerage commissions were $26,486.

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,
1996, the Fund paid  commissions  of $43,425 to compensate  brokers for research
services  such as industry,  economic  and company  reviews and  evaluations  of
securities.  During the fiscal period from January 1, 1997 to May 31, 1997,  the
Fund did not pay  commissions  to compensate  any brokers for research  services
such as industry, economic and company reviews and evaluations of securities.

The  Adviser's  indirect  parent,  the  Life  Company,   is  the  indirect  sole
shareholder of John Hancock Distributors,  Inc., a broker-dealer ("Distributors"
or "Affiliated  Broker").  Pursuant to procedures determined by the Trustees and
consistent  with the above  policy of obtaining  best net results,  the Fund may
execute portfolio  transactions with or through Affiliated  Brokers.  During the
fiscal  years ended  December  31,  1996 and 1995,  the Fund did not execute any
portfolio  transactions  with  Affiliated  Brokers.  For the fiscal  period from
January  1,  1997 to May 31,  1997,  the  Fund  did not  execute  any  portfolio
transactions with Affiliated Brokers.
    

                                       44

<PAGE>

Distributors may act as broker for the Fund on exchange  transactions,  subject,
however,  to the general  policy of the Fund set forth above and the  procedures
adopted by the Trustees pursuant to the Investment Company Act. Commissions paid
to an  Affiliated  Broker  must be at least as  favorable  as  those  which  the
Trustees believe to be contemporaneously  charged by other brokers in connection
with comparable  transactions  involving  similar  securities being purchased or
sold. A transaction  would not be placed with an  Affiliated  Broker if the Fund
would have to pay a commission rate less favorable than the Affiliated  Broker's
contemporaneous  charges for comparable transactions for its other most favored,
but unaffiliated,  customers except for accounts for which the Affiliated Broker
acts as 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.

Other investment  advisory clients advised by the Adviser may also invest in the
same  securities as the Fund. When these clients buy or sell the same securities
at  substantially  the same time, the Adviser may average the transactions as to
price and  allocate the amount of  available  investments  in a manner which the
Adviser  believes to be equitable to each client,  including  the Fund.  In some
instances,  this  investment  procedure may  adversely  affect the price paid or
received by the Fund or the size of the position obtainable for it. On the other
hand, to the extent  permitted by law, the Adviser may aggregate the  securities
to be sold or  purchased  for the Fund with  those to be sold or  purchased  for
other clients managed by it in order to obtain best execution.

TRANSFER AGENT SERVICES

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

APPENDIX

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.

                                      A-1

<PAGE>

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.

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.

                                      A-2

<PAGE>

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.

     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

          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."

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.

to time.

2.02  JHSS agrees that it will perform the following services:

         (a) In  accordance  with  procedures  established  from time to time by
         agreement between the Fund and JHSS, JHSS shall:


                                       1

<PAGE>

               (i) Receive for  acceptance,  orders for the  purchase of Shares,
               and  promptly  deliver  payment  and  appropriate   documentation
               therefor  to the  Fund's  Custodian  authorized  pursuant  to the
               Fund's  Declaration  of Trust or Articles of  Incorporation  (the
               "Custodian");

               (ii) Pursuant to purchase orders, issue the appropriate number of
               Shares  and  hold  such  Shares  in the  appropriate  Shareholder
               account;

               (iii) Receive for acceptance,  redemption requests and redemption
               directions and deliver the appropriate  documentation therefor to
               the Custodian;

               (iv) At the appropriate  time as and when it receives monies paid
               to it by the Custodian with respect to any  redemption,  pay over
               or cause to be paid over in the appropriate manner such monies as
               instructed by the redeeming Shareholders;

               (v) Effect  transfers of Shares by the registered  owners thereof
               upon receipt of appropriate instructions;

               (vi)   Prepare  and   transmit   payments   for   dividends   and
               distributions  declared by the Fund,  processing the reinvestment
               of distributions on the Fund at the net asset value per share for
               the Fund next computed after the payment (in accordance  with the
               Fund's then-current prospectus);

               (vii) Maintain records of account for and advise the Fund and its
               Shareholders as to the foregoing; and

               (viii)  Record the  issuance  of Shares of the Fund and  maintain
               pursuant to Rule  17Ad-10(e) of the rules and  regulations of the
               Securities  Exchange  Act of 1934 a record of the total number of
               Shares of the Fund which are authorized, based upon data provided
               to it by the Fund,  and issued and  outstanding.  JHSS shall also
               provide the Fund,  on a regular  basis,  with the total number of
               Shares which are authorized and issued and  outstanding and shall
               have no  obligation,  when  recording the issuance of Shares,  to
               monitor the issuance of these Shares or to take cognizance of any
               laws  relating  to the  issue  or sale  of  these  Shares,  which
               functions shall be the sole responsibility of the Fund.

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

         (c) In  addition  to and not in lieu of the  services  set forth in the
         above  paragraph  (a),  JHSS shall:  (i)  perform all of the  customary
         services of a transfer agent and dividend  disbursing  agent  including
         but not limited to:  maintaining  all Shareholder  accounts,  preparing
         Shareholder  meeting lists,  mailing proxies,  receiving and tabulating
         proxies,  mailing  Shareholder  reports  and  prospectuses  to  current
         Shareholders, withholding taxes on U.S. resident and non-resident alien
         accounts,  preparing and filing appropriate forms required with respect
         to  dividends  and   distributions  by  federal   authorities  for  all
         Shareholders,  preparing and mailing  confirmation forms and statements
         of account to Shareholders  for all purchases and redemptions of Shares

                                       2

<PAGE>

         and other confirmable  transactions in Shareholder accounts,  preparing
         and  mailing  activity  statements  for  Shareholders,   and  providing
         Shareholder  account  information  and (ii) provide a system which will
         enable the Fund to monitor the total  number of the Fund's  Shares sold
         in each State.

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

         (e) Additionally, JHSS shall:

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

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

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

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

                                       3

<PAGE>

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

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

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

Procedures  applicable to certain of these services may be established from time
to time by agreement between the Fund and JHSS.


Article 3      Fees and Expenses

          (b) The Fund's  refusal  or  failure to comply  with the terms of this
          Agreement,  or  which  arise  out  of  the  Fund's  bad  faith,  gross

          or in violation of any stop order or other  determination or ruling by
          any federal  agency or any state with  respect to the offer or sale of
          Shares in that state.

          (f) It is  understood  and  agreed  that the assets of the Fund may be
          used to satisfy the indemnity  under this Article 6 only to the extent
          that the loss, damage, cost, charge, counsel fee, payment, expense and
          liability arises out of or is attributable to services  hereunder with
          respect to the Shares of such Fund.

for its own acts and omissions.

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

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

RE:   John Hancock Sovereign Bond Fund
         file Nos. 2-48925; 811-2402    (0000045288)


Ladies and Gentlemen:

In  connection  with the filing of Amendment No. 26 pursuant to Rule 24e-2 under
the Investment  Company Act of 1940, as amended,  registering by  Post-Effective
Amendment No. 43 under the Securities Act of 1933, as amended,  4,961,726 shares
of the John  Hancock  Sovereign  Bond Fund (the  "Trust") in reliance  upon Rule
24e-2, it is the opinion of the  undersigned  that such shares will when sold be
legally issued, fully paid and nonassessable.

In  connection  with this opinion it should be noted that the Trust is an entity
of  the  type  generally  known  as  a  "Massachusetts  business  trust."  Under
Massachusetts  law,  shareholders of a Massachusetts  business trust may be held
personally  liable  for the  obligations  of the  Trust.  However,  the  Trust's
Declaration  of Trust  disclaims  shareholder  liability for  obligations of the
Trust and indemnifies shareholders of the Trust, with this indemnification to be
paid solely out of the assets of the Trust. Therefore, the shareholders' risk is
limited to  circumstances  in which the assets of the Trust are  insufficient to
meet the obligations asserted against the Trust's assets.

                                                     Sincerely,

                                                     /s/Timothy M. Fagan

                                                     Timothy M. Fagan
                                                     Assistant Secretary
                                                     Member of Massachusetts Bar
