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 $20 billion in assets.

Government Income Fund

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

GOAL AND STRATEGY

[Clipart] 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

[Clipart] 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
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,
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

[Clipart] 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

[Clipart] 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

[Clipart] 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

[Clipart] Under normal circumstances, the fund invests at least 65% of assets in
bonds rated lower than BBB/Baa and their unrated equivalents. Up to 10% 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

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

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

PORTFOLIO MANAGEMENT

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

 Management fee                                0.56%     0.56%
 12b-1 fee(3)                                  0.25%     1.00%
 Other expenses                                0.29%     0.29%
 Total fund operating expenses                 1.10%     1.85%

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     $88      $120      $197
   Assuming no redemption          $19     $58      $100      $197

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

[Clipart] 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

[Clipart] Under normal circumstances, the fund invests at least 65% of assets
in securities that are issued, or guaranteed as to principal and interest, by
the U.S. Government, its agencies or instrumentalities. These may include
Treasuries and mortgage-backed securities such as Ginnie Maes and Fannie Maes.
The fund may invest up to 35% 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 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

[Clipart] 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

[Clipart] 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

[Clipart] 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.

 12b-1 fee                                         0.25%     1.00%
 Other expenses (after limitation)(3)              0.50%     0.50%
 Total fund operating expenses 
 (after limitation)(3)                             0.75%     1.50%
    

(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).

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                  $37      $53      $70      $120
 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.

(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
     0.72% for each class and total fund operating expenses would be 1.37% for
     Class A and 2.02% 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

[Clipart] 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

[Clipart] 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

   
[Clipart] 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

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

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

 Class B shares
   Assuming redemption
   at end of period              $51     $85      $111     $198
   Assuming no redemption        $21     $65      $111     $198

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

[Clipart] 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

[Clipart] 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

[Clipart] 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

[Clipart] 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.

Sovereign U.S. Government Income Fund

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

GOAL AND STRATEGY

[Clipart] 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

[Clipart] 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

[Clipart] 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

[Clipart] 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.

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

 Other expenses                                   0.35%     0.35%
 Total fund operating expenses                    1.15%     1.85%

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      $105     $178
 Class B shares
   Assuming redemption
   at end of period              $69     $88      $120     $198

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

[Clipart] 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

[Clipart] 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

[Clipart] 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

[Clipart] 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

[Clipart] 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.

 Annual fund operating expenses (as a % of average net assets)
- --------------------------------------------------------------------------------
 Management fee                                   0.45%     0.45%
 12b-1 fee(3)                                     0.30%     1.00%
 Other expenses                                   0.28%     0.28%
 Total fund operating expenses                    1.03%     1.73%

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      $76       $99      $165
 Class B shares
   Assuming redemption
   at end of period                  $68      $84      $114      $186
   Assuming no redemption            $18      $54       $94      $186

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.

- --------------------------------------------------------------------------------
Class A                                 Class B
- --------------------------------------------------------------------------------

o  Front-end sales charges, as          o  No front-end sales charge; all   
   described below. There are              your money goes to work for you  
   several ways to reduce these            right away.                      
   charges, also described below.                                           
                                        o  Higher annual expenses than      
o  Lower annual expenses than Class        Class A shares.                  
   B shares.                                                                
                                        o  A deferred sales charge, as 
                                           described below. 
                                                                            
                                        o  Automatic conversion to Class A 
                                           shares after either five years
                                           (Group 1) or eight 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:

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 priviliges. Each investor has an individual
account, but for sales charge purposes the group's investments are lumped
together, making the investors potentially eligible for reduced sales charges.
There is no charge, no obligation to invest (although initial aggregate
investments must be at least $250), and 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

sales charges or CDSCs to various individuals and institutions, including:

   non-discretionary accounts

   John Hancock funds

   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  in the case of Limited-Term Government Fund, anyone investing 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.

Selling shares in writing In certain circumstances, you will need to make your
request to sell shares in writing. You may need to include additional items with
your request, as shown in the table below. You may also need to include a
signature guarantee, which protects you against fraudulent orders. You will need
a signature guarantee if: 

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

You 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
o  a securities exchange or clearing agency

A  notary public CANNOT provide a signature guarantee.

TRANSACTION POLICIES

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

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

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

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

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

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

Dividends The funds generally declare dividends daily and pay them monthly.
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, 


24 YOUR ACCOUNT

<PAGE>

you can choose to have a check for your dividends mailed to you. However, if the
check is not deliverable, your dividends will be reinvested.

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

Consequently, dividends you receive from a fund, whether reinvested or taken as
cash, are generally considered taxable. Dividends from a fund's long-term
capital gains are taxable as capital gains; dividends from other sources are
generally taxable as ordinary income. 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.

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.

 Government Income               $   9,835,482          4.85%

 Intermediate Maturity Gov.      $     253,107          2.30%

 Strategic Income                $   5,169,665          3.18%
    

(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 affect 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.
