     0.47% for each class and total fund  operating  expenses would be 1.12% for
     Class A and 1.87% for Class B.

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.

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              $70     $91      $124     $206

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.

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.

 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.

- --------------------------------------------------------------------------------
 Shareholder transaction expenses                Class A   Class B

 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.

(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.

REGISTRANT NAME: SOVEREIGN BOND FUND

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

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.

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

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(3)                                     0.30%     1.00%
 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
   Assuming no redemption        $19     $58      $100     $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.

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.

 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.

                                           (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:

 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 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

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.

                                                                       [Clipart]

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.
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, 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.

 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.

ORGANIZATION OF THE FUNDS

Each Fund is a series of the Trust, an open-end  management  investment  company
organized as a  Massachusetts  business  trust on December  12,  1984.  Prior to
December 22, 1994, John Hancock  Government Income Fund was called  Transamerica
Government  Income  Fund  and John  Hancock  High  Yield  Bond  Fund was  called
Transamerica  High  Yield Bond Fund.  Prior to August 30,  1996,  the Funds were
series of John Hancock Series, Inc., a Maryland corporation.

John  Hancock  Advisers,  Inc.  (the  "Adviser"),   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 OBJECTIVES AND POLICIES

The following  information  supplements the discussion of the Fund's  investment
objective and policies  discussed in the  Prospectus.  There can be no assurance
that either Fund will achieve its respective investment objective.

John Hancock  Government  Income Fund's  investment  objective is to earn a high
level of current income  consistent  with  preservation  of capital by investing
primarily  in  securities  that are issued or  guaranteed  as to  principal  and
interest by the U.S. Government, its agencies or instrumentalities. The Fund may
seek to enhance  its  current  return and may seek to hedge  against  changes in
interest rates by engaging in transactions involving options (subject to certain
limits),  futures and options on futures.  The Fund  expects  that under  normal
market  conditions  it will  invest  at least  80% of its  total  assets in U.S.
Government   securities   (and  related   repurchase   agreements   and  forward
commitments). The Fund may take full advantage of the entire range of maturities
of  U.S.  Government  securities  and may  adjust  the  dollar-weighted  average
maturity of its portfolio from time to time based in large part on the Adviser's
expectation of future changes in interest rates.

As to the balance of the Fund's  assets,  where  consistent  with the investment
objective, the Fund may:

     1. invest in U.S.  dollar  denominated  securities  issued or guaranteed by
foreign  governments which are considered  stable by the Adviser,  or any of the
political  subdivisions,  instrumentalities,  authorities  or  agencies of these
governments.  These  securities  generally will be rated within the four highest
rating categories by a nationally  recognized rating organization (e.g. Standard
& Poor's Rating Group ("S&P") or Moody's Investors Service, Inc. ("Moody's")) or
if not so rated,  determined to be of  equivalent  quality in the opinion of the
Adviser;  provided  that the Fund may  invest up to 10% of its  total  assets in
securities  which  may be rated B or better by a  nationally  recognized  rating
organization.

     2. invest in other  "asset  backed  securities"  which are not  included as
"government  asset  backed":  securities and are rated in one of the two highest
rating categories by a nationally  recognized  credit rating  organization or if
not so rated,  determined to be of equivalent  investment quality in the opinion
the Adviser;

     3. engage in hedging transactions, including options, interest rate futures
contracts and options thereon, subject to certain limitations described below;

     4. enter into repurchase  agreements and reverse repurchase  agreements and
invest in when issued securities and restricted  securities,  subject to certain
limitations described below;

     5.  invest  in (for  liquidity  purposes)  high  quality,  short-term  debt
securities  with  remaining  maturities  of one  year  or  less  ("money  market
instruments") such as certificates of deposit,  bankers' acceptances,  corporate
debt securities, commercial paper and related repurchase agreements.

                                       2

<PAGE>

Asset backed  securities,  like Ginnie Mae  certificates,  are securities  which
represent a  participation  in or are secured by and payable  from,  a stream of
payments generated by particular assets,  most often a pool of assets similar to
one  another.   Types  of  other  asset  backed  securities  include  automobile
receivable  securities,  credit card  receivable  securities and mortgage backed
securities such as collateralized  mortgage obligations ("CMOs") and real estate
mortgage investment conduits ("REMICs").

John Hancock High Yield Bond Fund's primary investment  objective is to maximize
current  income  without  assuming  undue  risk by  investing  in a  diversified
portfolio  consisting  primarily of  lower-rated,  high  yielding,  fixed income
securities, such as: domestic and foreign corporate bonds; debentures and notes;
convertible  securities;  preferred stocks;  and domestic and foreign government
obligations. As a secondary objective, the Fund seeks capital appreciation,  but
only when it is  consistent  with the primary  objective of  maximizing  current
income.  The Fund's  investment  objectives may not be changed  without 30 days'
prior written notice to shareholders.

Under normal market  conditions,  at least 65% of the Fund's total assets may be
invested in bonds or  debentures  rated  "Baa" or lower by Moody's,  or "BBB" or
lower by S&P;  however,  no more  than 10% of the  Fund's  total  assets  may be
invested in securities  that are rated as low as "CC" by S&P or "Ca" by Moody's.
Unrated  securities  will also be considered for investment by the Fund when the
Adviser  believes  that the  issuer's  financial  condition,  or the  protection
afforded by the terms of the securities themselves,  limits the risk to the Fund
to a degree  comparable to that of rated  securities  consistent with the Fund's
objectives and policies.

The Fund's  investments  in debt  securities  may include  zero coupon bonds and
payment-in-kind  bonds.  Zero coupon bonds are issued at a significant  discount
from  their  principal   amount  in  lieu  of  paying   interest   periodically.
Payment-in-kind  bonds allow the issuer, at its option, to make current interest
payments on the bonds either in cash or in additional  bonds.  The market prices
of zero coupon and  payment-in-kind  bonds are  affected to a greater  extent by
interest  rate changes,  and thereby tend to be more  volatile  than  securities
which pay interest  periodically  and in cash.  The Fund accrues income on these
securities  for tax and accounting  purposes,  and this income is required to be
distributed  to  shareholders.  Because no cash is  received  at the time income
accrues  on  these  securities,  the  Fund  may be  forced  to  liquidate  other
investments to make distributions. At times when the Fund invests in zero-coupon
and  payment-in-kind  bonds,  it will not be pursuing  its primary  objective of
maximizing current income.

Although the Fund intends to maintain  investment emphasis on debt securities of
domestic issuers,  the Fund may invest without  limitation in debt securities of
foreign issuers,  including those issued by  supranational  entities such as the
World Bank. The Fund may also purchase debt securities  issued in an any country
developed   or   undeveloped.   Investments   in   securities   of   issuers  in
non-industrialized  countries  generally involve more risk and may be considered
speculative.  The Fund may also enter into  forward  foreign  currency  exchange
contracts for the purchase or sale of foreign currency for hedging purposes. The
risks of foreign investments should be carefully considered by investors.

Included  among domestic debt  securities  eligible for purchase by the Fund are
adjustable and variable or floating rate securities, mortgage related securities
(including  stripped   securities,   collateralized   mortgage  obligations  and
multi-class  pass-through  securities),  asset-backed  securities  and  callable
bonds.  Callable bonds have a provision  permitting the issuer, at its option to
"call" or redeem the bonds.  If an issuer were to redeem  bonds held by the Fund
during  a time of  declining  interest  rates,  the  Fund  might  not be able to
reinvest the  proceeds in bonds  providing  the same coupon  return as the bonds
redeemed.

To the extent that the Fund does not invest in the securities  described  above,
the Fund may:

                                       3

<PAGE>

     1.  invest  (for  liquidity  purposes ) in high  quality,  short-term  debt
securities  with  remaining  maturities  of one  year  or  less  ("money  market
instruments")  including  government   obligations,   certificates  of  deposit,
bankers' acceptances, short-term corporate debt securities, commercial paper and
related repurchase agreements;

     2. invest up to 10% of its total assets in municipal obligations, including
municipal  bonds  issued at a  discount,  in  circumstances  where  the  Adviser
determines  that  investing  in such  obligations  would  facilitate  the Fund's
ability to accomplish its investment objectives;

     3. lend its portfolio  securities,  enter into  repurchase  agreements  and
reverse repurchase  agreements,  purchase restricted and illiquid securities and
purchase securities on a when issued or forward commitment basis;

     4. write  (sell)  covered  call and put options and  purchase  call and put
options on debt  securities  and  securities  indices  in an effort to  increase
current income and for hedging purposes; and

     5. purchase and sell interest rate futures contracts on debt securities and
securities  index  futures  contracts,  and write and purchase  options on these
futures contracts for hedging purposes.

During  periods of unusual  market  conditions  when the Adviser  believes  that
investing for temporary  defensive  purposes is appropriate,  part or all of the
assets of the Fund may be invested in cash or cash equivalents consisting of:

     1.  obligations  of banks  (including  certificates  of  deposit,  bankers'
acceptances and repurchase agreements ) with assets of $100,000,0000 or more;

     2.  commercial  paper rated within the two highest  rating  categories of a
nationally recognized rating organization;

     3. investment grade short-term notes;

     4.  obligations  issued or guaranteed by the U.S.  Government or any of its
agencies or instrumentalities; and

     5. related repurchase agreements.

As a matter of fundamental policy, the Fund will not invest more than 25% of its
total assets (taken at market value) in the securities of issuers engaged in any
one  industry,  except  that the Fund may  invest  up to 40% of the value of its
total assets in the  securities of issuers  engaged in the electric  utility and
telephone  industries.  The Adviser  follows a policy of not causing the Fund to
invest more than 25% of its total assets in the securities of issuers engaged in
the electric utility industry or the telephone  industry unless yields available
for four  consecutive  weeks in the four highest rating  categories on new issue
bonds in this industry (issue size of $50 million or more) have averaged greater
than the yields of new issue long-tern  industrial  bonds similarly rated (issue
size of $50  million or more) and,  in the opinion  the  Adviser,  the  relative
return  available  from the  electric  utility  or  telephone  industry  and the
relative risk,  marketability,  quality and  availability  of securities of this
industry  justifies such an investment.  Obligations issued or guaranteed by the
U.S.  Government  or its agencies and  instrumentalities  are not subject to the
foregoing  25%  limitation.  In  addition,  for  purposes  of  this  limitation,
determinations  of what  constitutes  an industry  are made in  accordance  with
specific  industry  codes set forth in the  Standard  Industrial  Classification
Manual and without considering groups of industries (e.g., all utilities,  to be
an industry.

Government Securities. Each Fund may invest in U.S. Government securities, which
are  obligations  issued or guaranteed by the U.S.  Government and its agencies,

                                       4

<PAGE>

authorities or instrumentalities.  Certain U.S. Government securities, including
U.S.  Treasury  bills,  notes  and  bonds,  and  Government   National  Mortgage
Association  certificates  ("Ginnie Maes"),  are supported by the full faith and
credit of the United States. Certain other U.S. Government securities, issued or
guaranteed by Federal  agencies or  government  sponsored  enterprises,  are not
supported  by the  full  faith  and  credit  of the  United  States,  but may be
supported  by the right of the issuer to borrow  from the U.S.  Treasury.  These
securities  include  obligations  of the Federal Home Loan Mortgage  Corporation
("Freddie   Macs"),   and   obligations   supported   by  the   credit   of  the
instrumentality,  such as Federal National  Mortgage  Association Bonds ("Fannie
Maes").

Custodial Receipts. The Funds may acquire custodial receipts for U.S. government
securities.  Custodial  receipts evidence ownership of future interest payments,
principal  payments or both, and include Treasury  Receipts,  Treasury Investors
Growth Receipts  ("TIGRs"),  and Certificates of Accrual on Treasury  Securities
("CATS").
Custodial receipts are not considered U.S. government securities.

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

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

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

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

                                       5

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

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

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

Issuers of municipal  obligations  are subject to the  provisions of bankruptcy,
insolvency and other laws  affecting the rights and remedies of creditors,  such
as the  Federal  Bankruptcy  Act,  and laws,  if any,  which may be  enacted  by
Congress or state  legislatures  extending  the time for payment of principal or
interest,  or both,  or imposing  other  constraints  upon  enforcement  of such
obligations.  There is also the  possibility  that as a result of  litigation or
other conditions the power or ability of any one or more issuers to pay when due
the principal of and interest on their municipal obligations may be affected.

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

Mortgage-Backed  Securities.  The Funds  may  invest  in  mortgage  pass-through
certificates and  multiple-class  pass-through  securities,  such as real estate
mortgage investment conduits REMIC, CMOs and stripped mortgage-backed securities
("SMBS"), and other types of "Mortgage-Backed  Securities" that may be available
in the future.

Guaranteed Mortgage  Pass-Through  Securities.  Guaranteed mortgage pass-through
securities  represent  participation  interests in pools of residential mortgage
loans and are issued by U.S.  Governmental  or private lenders and guaranteed by
the U.S. Government or one of its agencies or  instrumentalities,  including but
not limited to Ginnie Mae, Fannie Mae and Freddie Macs.

Multiple-Class  Pass-Through Securities and Collateralized Mortgage Obligations.
CMOs and REMIC  pass-through  or  participation  certificates  may be issued by,
among others, U.S. Government agencies and  instrumentalities as well as private
lenders.  CMOs and REMIC  certificates  are issued in  multiple  classes and the

                                       6

<PAGE>

principal  of and interest on the  mortgage  assets may be  allocated  among the
several  classes of CMOs or REMIC  certificates  in various ways.  Each class of
CMOs or REMIC  certificates,  often  referred to as a "tranche,"  is issued at a
specific  adjustable  or fixed  interest rate and must be fully retired no later
than its final distribution date. Generally,  interest is paid or accrues on all
classes of CMOs or REMIC certificates on a monthly basis.

Typically,  CMOs are  collateralized  by Ginnie  Mae,  Fannie Mae or Freddie Mac
certificates  but also may be  collateralized  by other mortgage  assets such as
whole loans or private mortgage pass-through securities. Debt service on CMOs is
provided  from  payments of principal  and interest on  collateral  of mortgaged
assets and any reinvestment income thereon.

A REMIC is a CMO that  qualifies  for special tax  treatment  under the Internal
Revenue Code of 1986, as amended (the "Code"),  and invests in certain mortgages
primarily secured by interests in real property and other permitted investments.
Investors may purchase "regular" or "residual" interests in REMICs, although the
Funds do not  intend,  absent a change in current tax law, to invest in residual
interests.

Stripped  Mortgage-Backed   Securities.   SMBS  are  derivative   multiple-class
mortgage-backed  securities.  SMBS are usually  structured with two classes that
receive different proportions of interest and principal  distributions on a pool
of mortgage  assets.  A typical SMBS will have one class  receiving  some of the
interest and most of the  principal,  while the other class will receive most of
the interest and the remaining  principal.  In the most extreme case,  one class
will receive all of the  interest  (the  "interest  only" class) while the other
class will receive all of the principal (the "principal only" class). The yields
and market risk of interest only and principal only SMBS,  respectively,  may be
more volatile than those of other fixed income securities.  The staff of the SEC
considers privately issued SMBS to be illiquid.

Structured or Hybrid Notes.  Government Income Fund and High Yield Bond Fund may
invest in  "structured"  or  "hybrid"  notes.  The  distinguishing  feature of a
structured  or hybrid  note is that the  amount  of  interest  and/or  principal
payable on the note is based on the  performance of a benchmark  asset or market
other  than  fixed  income  securities  or  interest  rates.  Examples  of these
benchmarks include stock prices,  currency exchange rates and physical commodity
prices.  Investing  in a structured  note allows a Fund to gain  exposure to the
benchmark  market while fixing the maximum loss that the Fund may  experience in
the event that market does not perform as  expected.  Depending  on the terms of
the note, a Fund may forego all or part of the interest and principal that would
be payable on a comparable  conventional  note; a Fund's loss cannot exceed this
foregone interest and/or principal.  An investment in structured or hybrid notes
involves  risks  similar to those  associated  with a direct  investment  in the
benchmark asset.

   
Participation  Interests.  Participation  interests,  which may take the form of
interests in, or assignments of certain loans,  are acquired from banks who have
made these loans or are members of a lending  syndicate.  The Fund's investments
in  participation  interests may be subject to its 10% limitation on investments
in illiquid securities.
    

Risk  Factors   Associated  with   Mortgage-Backed   Securities.   Investing  in
Mortgage-Backed  Securities  involves certain risks,  including the failure of a
counter-party  to meet its  commitments,  adverse  interest rate changes and the
effects of  prepayments  on mortgage cash flows.  In addition,  investing in the
lowest  tranche of CMOs and REMIC  certificates  involves risks similar to those
associated   with   investing   in  equity   securities.   Further,   the  yield
characteristics of  Mortgage-Backed  Securities differ from those of traditional
fixed income securities.  The major differences  typically include more frequent
interest and principal payments (usually monthly), the adjustability of interest
rates,   and  the  possibility   that  prepayments  of  principal  may  be  made
substantially earlier than their final distribution dates.

                                       7

<PAGE>

Prepayment  rates are  influenced  by changes in  current  interest  rates and a
variety  of  economic,  geographic,  social  and  other  factors  and  cannot be
predicted with  certainty.  Both  adjustable  rate mortgage loans and fixed rate
mortgage  loans may be 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
rate  and  prepayment  rate  scenarios,  a Fund  may fail to  recoup  fully  its
investment in Mortgage-Backed  Securities notwithstanding any direct or indirect
governmental,   agency  or  other  guarantee.  When  a  Fund  reinvests  amounts
representing payments and unscheduled prepayments of principal, it may receive a
rate of  interest  that is  lower  than  the rate on  existing  adjustable  rate
mortgage  pass-through  securities.   Thus,   Mortgage-Backed   Securities,  and
adjustable  rate mortgage  pass-through  securities in  particular,  may be less
effective than other types of U.S. Government  securities as a means of "locking
in" interest rates.

Conversely,  in a rising interest rate environment,  a declining prepayment rate
will  extend  the  average  life  of  many  Mortgage-Backed   Securities.   This
possibility is often referred to as extension  risk.  Extending the average life
of a Mortgage-Backed  Security  increases the risk of depreciation due to future
increases in market interest rates.

Risk Associated with Mortgage-backed  Securities.  Different types of derivative
debt securities are subject to different  combinations of prepayment,  extension
and/or interest rate risk.  Conventional  mortgage pass- through  securities and
sequential  pay CMOs are subject to all of these risks,  but are  typically  not
leveraged.  Thus,  the magnitude of exposure may be less than for more leveraged
Mortgage-Backed Securities.

The risk of early  prepayments is the primary risk associated with interest only
debt  securities  ("IOs"),   super  floaters,   other  leveraged  floating  rate
instruments and Mortgage-Backed  Securities  purchased at a premium to their par
value.  In some  instances,  early  prepayments may result in a complete loss of
investment in certain of these  securities.  The primary risks  associated  with
certain other derivative debt securities are the potential  extension of average
life and/or depreciation due to rising interest rates.

These  securities  include  floating rate securities  based on the Cost of Funds
Index ("COFI floaters"), other "lagging rate" floating rate securities, floating
rate securities that are subject to a maximum interest rate ("capped floaters"),
Mortgage-Backed  Securities purchased at a discount,  leveraged inverse floating
rate securities  ("inverse  floaters"),  principal only debt securities ("POs"),
certain residual or support tranches of CMOs and index amortizing  notes.  Index
amortizing  notes  are  not  Mortgage-Backed  Securities,  but  are  subject  to
extension  risk  resulting  from the issuer's  failure to exercise its option to
call or redeem the notes before their stated  maturity date.  Leveraged  inverse
IOs combine several elements of the Mortgage-Backed  Securities  described above
and thus present an especially intense combination of prepayment,  extension and
interest rate risks.

Planned  amortization  class ("PAC") and target  amortization  class ("TAC") CMO
bonds 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." To the extent that  prepayment  rates
remain within these prepayment  ranges,  the residual or support tranches of PAC
and TAC CMOs  assume the extra  prepayment,  extension  and  interest  rate risk
associated with the underlying mortgage assets.

Other types of floating rate  derivative  debt  securities  present more complex
types of interest  rate risks.  For example,  range  floaters are subject to the
risk that the  coupon  will be  reduced to below  market  rates if a  designated
interest rate floats outside of a specified  interest rate band or collar.  Dual
index or yield curve  floaters  are subject to  depreciation  in the event of an
unfavorable change in the spread between two designated interest rates. X- reset
floaters  have a coupon that  remains  fixed for more than one  accrual  period.

                                       8

<PAGE>

Thus, the type of risk involved in these securities depends on the terms of each
individual X-reset floater.

Convertible  Securities.   High  Yield  Bond  Fund  may  invest  in  convertible
securities.  Convertible securities may be converted at either a stated price or
stated  rate  into  underlying  shares  of  common  stock  of the  same  issuer.
Convertible securities have general characteristics similar to both fixed income
and equity securities.  The market value of convertible  securities  declines as
interest rates increase,  and increases as interest rates decline.  In addition,
because of the conversion  feature,  the market value of convertible  securities
tends to vary with  fluctuations  in the market value of the  underlying  common
stocks and therefore  will also react to  variations  in the general  market for
equity  securities.  A unique feature of  convertible  securities is that as the
market price of the underlying  common stock  declines,  convertible  securities
tend to trade increasingly on a yield basis, and consequently may not experience
market value  declines to the same extent as the underlying  common stock.  When
the market price of the  underlying  common stock  increases,  the prices of the
convertible  securities  tend  to  rise  as a  reflection  of the  value  of the
underlying  common  stock.  While no  securities  investments  are without risk,
investments  in  convertible   securities   generally   entail  less  risk  than
investments  in  common  stock of the  same  issuer.  However,  the  issuers  of
convertible securities may default on their obligations.

Mortgage "Dollar Roll"  Transactions.  The Funds may enter into mortgage "dollar
roll"  transactions with selected banks and  broker-dealers  pursuant to which a
Fund sells Mortgage-Backed Securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date. The Funds 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 a Fund's borrowing and other senior securities.  For financial  reporting and
tax  purposes,   each  Fund  treats   mortgage  dollar  rolls  as  two  separate
transactions;   one  involving  the  purchase  of  a  security  and  a  separate
transaction  involving  a sale.  Neither  Fund  currently  intends to enter into
mortgage rolls that are accounted for as financing.

Pay-In-Kind, Delayed and Zero Coupon Bonds. Each 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 of  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. A 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." At times when a Fund  invests in  pay-in-kind,
delayed and zero coupon bonds, it will not be pursuing its primary  objective of
maximizing current income.

Indexed  Securities.  High Yield  Bond Fund may  invest in  indexed  securities,
including  floating rate securities that are subject to a maximum  interest rate
("capped  floaters") and leveraged  inverse  floating rate securities  ("inverse
floaters") (up to 10% of the Fund's total assets). The interest rate or, in some
cases,  the principal  payable at the maturity of an indexed security may change
positively  or inversely in relation to one or more  interest  rates,  financial
indices or other financial indicators  ("reference prices"). An indexed security
may be leveraged to the extent that the  magnitude of any change in the interest
rate or principal  payable on an indexed security is a multiple of the change in

                                       9

<PAGE>

the  reference  price.  Thus,  indexed  securities  may  decline in value due to
adverse market changes in interest rates or other reference prices.

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

In a typical cap or floor  agreement,  one party  agrees to make  payments  only
under  specified  circumstances,  usually in return for  payment of a fee by the
other party. For example, the buyer of an interest rate cap obtains the right to
receive  payments  to the  extent  that a  specified  interest  rate  exceeds an
agreed-upon  level,  while the seller of an interest  rate floor is obligated to
make  payment 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 a Fund's investment exposure from one type of
investment  to another.  For example,  if a 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 a
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. A Fund may also suffer losses if
it is unable to terminate  outstanding  swap  agreements  or reduce its exposure
through offsetting transactions. Each Fund will maintain in a segregated account
with its custodian,  cash or liquid  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.

Asset-Backed  Securities.  Government  Income  Fund and High Yield Bond Fund may
invest a portion of their  assets in  asset-backed  securities.  For  Government
Income Fund,  these  securities  must be rated in one of the two highest  rating
categories by a nationally recognized statistical rating organization (e.g., S&P
or Moody's) or if not so rated, of equivalent  investment quality in the opinion
of the Adviser.

Asset-backed  securities  are often subject to more rapid  repayment  than their
stated  maturity  date  would  indicate  as a  result  of  the  pass-through  of
prepayments  of principal on the underlying  loans.  During periods of declining
interest rates,  prepayment of loans underlying  asset-backed  securities can be
expected to accelerate.  Accordingly,  a Fund's ability to maintain positions in
such 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

                                       10

<PAGE>

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.

Lower Rated High Yield Debt  Obligations.  Government Income Fund and High Yield
Bond Fund may invest in high  yielding,  fixed  income  securities  rated  below
investment  grade  (e.g.,  rated  below  Baa by  Moody's  or below  BBB by S&P),
sometimes  referred  to as junk  bonds.  No more than 10% of  Government  Income
Fund's total assets may be invested in these  securities,  and Government Income
Fund may not invest in securities rated lower than B by a nationally  recognized
rating  organization.  Ratings  are based  largely on the  historical  financial
condition of the issuer.  Consequently,  the rating  assigned to any  particular
security is not  necessarily  a  reflection  of the issuer's  current  financial
condition, which may be better or worse than the rating would indicate.

See the Appendix to this Statement of Additional Information which describes the
characteristics of corporate bonds in the various rating categories.  High Yield
Bond Fund may invest in comparable  quality  unrated  securities  which,  in the
opinion of the Adviser,  offer  comparable  yields and risks to those securities
which are rated.

Debt obligations  rated in the lower ratings  categories,  or which are unrated,
involve greater volatility of price and risk of loss of principal and income. In
addition,  lower ratings  reflect a greater  possibility of an adverse change in
financial  condition  affecting  the  ability of the issuer to make  payments of
interest and principal. The high yield fixed income market is relatively new and
its growth  occurred during a period of economic  expansion.  The market has not
yet been fully tested by an economic recession.

The market price and liquidity of lower rated fixed income securities  generally
respond to short term corporate and market developments to a greater extent than
do the price and liquidity of higher rated securities  because such developments
are perceived to have a more direct  relationship to the ability of an issuer of
such 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 to value  accurately  a Fund's  assets.  The reduced  availability  of
reliable, objective data may increase a Fund's reliance on management's judgment
in valuing high yield bonds.  In addition,  a Fund's  investments  in high yield
securities  may be susceptible  to adverse  publicity and investor  perceptions,
whether or not  justified by  fundamental  factors.  A Fund's  investments,  and
consequently its net asset value, will be subject to the market fluctuations and
risks inherent in all securities.

Ratings as  Investment  Criteria  In  general,  the  ratings of Moody's  and S&P
represent  the  opinions of these  agencies as to the quality of the  securities
which they rate. It should be emphasized however,  that ratings are relative and
subjective and are not absolute standards of quality.  These rating will be used
by the Funds as initial  criteria for the  selection  of  portfolio  securities.
Among the factors  which will be  considered  are the  long-term  ability of the
issuer to pay principal  and interest and general  economic  trends.  Appendix A
contains further information  concerning the rating of Moody's and S&P and their
significance.  Subsequent  to its purchase by the Funds,  an issue of securities
may cease to be rated,  or its rating may be reduced below the minimum  required
for purchase by the Funds.  Neither of these events will require the sale of the
securities by the Funds.

                                       11

<PAGE>

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.

Brady  Bonds.  The Funds  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  issued by U.S.  Treasury  Secretary  Nicholas  F. Brady in 1989 as a
mechanism  for  debtor  nations  to  restructure  their   outstanding   external
indebtedness  (generally,  commercial bank debt). In restructuring  its external
debt  under  the Brady  Plan  framework,  a debtor  nation  negotiates  with its
existing  bank lenders as well as  multilateral  institutions  such as the World
Bank and the International  Monetary Fund (the "IMF"). The Brady Plan facilitate
the exchange of  commercial  bank debt for newly issued  (known as Brady Bonds).
The World Bank and 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
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  promote
the debtor country's ability to service its external obligations and promote its
economic growth and development.  The Brady Plan only sets forth general guiding
principles for economic  reform and debt reduction,  emphasizing  that solutions
must be negotiated on a  case-by-case  basis  between  debtor  nations and their
creditors. The Adviser believes that economic reforms undertaken by countries in
connection  with the  issuance of Brady Bonds make the debt of  countries  which
have  issued  or have  announced  plans  to  issue  Brady  Bonds  an  attractive
opportunity for investment.

Brady Bonds have  recently  been issued by Argentina,  Brazil,  Bulgaria,  Costa
Rica,  Dominican  Republic,   Ecuador,  Jordan,  Mexico,  Nigeria,  Poland,  the
Phillipines,  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 Funds are 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 along 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.

Investments  in Foreign  Securities.  Government  Income Fund may invest in U.S.
dollar  denominated  securities of foreign  governments.  These  securities will
generally  be rated within the four highest  rating  categories  by a nationally
recognized rating organization S&P or Moody's or if not so rated,  determined to
be of equivalent quality in the opinion of the Adviser; provided that Government
Income Fund may invest up to 10% of its total assets in securities  which may be
rated B or better by a nationally recognized rating organization.

                                       12

High Yield Bond Fund may invest in securities of foreign issuers, including debt
and equity  securities of corporate and  governmental  issuers in countries with
emerging economies or securities  markets.  High Yield Bond Fund may also invest
in American Depository Receipts ("ADRs"),  European Depository Receipts ("EDRs")
or other  securities  convertible  into  securities  of foreign  issuers.  These
securities  may not  necessarily  be  denominated  in the same  currency  as the
securities  into which they may be  converted  but rather in the currency of the
market  in which  they are  traded.  ADRs are  receipts  typically  issued by an
American bank or trust company which evidence ownership of underlying securities
issued by a foreign corporation.  EDRs are receipts issued in Europe by banks or
depositories which evidence a similar ownership arrangement. Generally, ADRs, in
registered  form, are designed for use in U.S.  securities  markets and EDRs, in
bearer form, are designed for use in European securities markets.

Foreign  Currency  Transactions.  High  Yield  Bond Fund may  engage in  foreign
currency  transactions.  The foreign currency exchange  transactions of the Fund
may be conducted on a spot (i.e., cash) basis at the spot rate for purchasing or
selling currency  prevailing in the foreign exchange market.  The Fund may enter
into forward foreign currency  exchange  contracts  involving  currencies of the
different  countries  in  which  it  may  invest  as a  hedge  against  possible
variations  in the foreign  exchange  rate  between  these  currencies.  Forward
contracts are agreements to purchase or sell a specified currency at a specified
future date and price set at the time of the  contract.  Transaction  hedging is
the  purchase or sale of forward  foreign  currency  contracts  with  respect to
specific  receivables  or payables of the Fund accruing in  connection  with the
purchase and sale of its portfolio  securities quoted or denominated in the same
or related foreign  currencies.  Portfolio hedging is the use of forward foreign
currency contracts to offset portfolio security positions  denominated or quoted
in the same or  related  foreign  currencies.  The  Fund's  dealings  in forward
foreign currency exchange  contracts will be limited to hedging either specified
transactions or portfolio  positions.  The Fund will not attempt to hedge all of
its foreign portfolio positions.

If High Yield Bond Fund enters into a forward contract  requiring it to purchase
foreign currency,  its custodian bank will segregate cash or liquid  securities,
of any  type or  maturity,  in a  separate  account  of the  Fund  in an  amount
necessary  to complete  the  forward  contract.  These  assets will be valued at
market  daily  and if  the  value  of the  securities  in the  separate  account
declines,  additional  cash or securities  will be placed in the account so that
the value of the  account  will  equal the amount of the  Fund's  commitment  in
purchased forward contracts.

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

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

Risks of Foreign  Securities.  Investments  in foreign  securities may involve a
greater  degree of risk than those in domestic  securities.  There is  generally
less  publicly  available  information  about  foreign  companies in the form of
reports and ratings  similar to those that are  published  about  issuers in the
United  States.  Also,  foreign  issuers  are  generally  not subject to uniform
accounting,  auditing and financial reporting  requirements  comparable to those
applicable to United States issuers.

Because foreign  securities may be denominated in currencies other than the U.S.
dollar,  changes in foreign  currency  exchange rates will affect the Fund's net
asset  value,  the value of  dividends  and  interest  earned,  gains and losses

                                       13

<PAGE>

realized on the sale of securities, and any net investment income and gains that
the Fund distributes to shareholders. Securities transactions undertaken in some
foreign markets may not be settled promptly,  so that the Fund's  investments on
foreign  exchanges  may be less  liquid and  subject to the risk of  fluctuating
currency exchange rates pending settlement.

Foreign  securities  will be purchased  in the best  available  market,  whether
through  over-the-counter  markets or exchanges  located in the countries  where
principal  offices of the issuers are located.  Foreign  securities  markets are
generally  not as developed or  efficient as those in the United  States.  While
growing in volume, they usually have substantially less volume than the New York
Stock Exchange,  and securities of some foreign issuers are less liquid and more
volatile than securities of comparable United States issuers.  Fixed commissions
on foreign exchanges are generally higher than negotiated  commissions on United
States exchanges,  although the Fund will endeavor to achieve the most favorable
net results on its portfolio  transactions.  There is generally less  government
supervision and regulation of securities  exchanges,  brokers and listed issuers
than in the United States.

With respect to certain foreign  countries,  there is the possibility of adverse
changes  in  investment   or  exchange   control   regulations,   expropriation,
nationalization or confiscatory taxation, limitations on the removal of funds or
other  assets  of the  Fund,  political  or social  instability,  or  diplomatic
developments  which could affect United States  investments in those  countries.
Moreover,  individual foreign economies may differ favorably or unfavorably from
the United States economy in terms of growth of gross national product,  rate of
inflation,  capital  reinvestment,  resource  self-sufficiency  and  balance  of
payments position.

The dividends in some cases,  capital gains,  and interest payable on certain of
the Fund's foreign portfolio securities may be subject to foreign withholding or
other foreign taxes,  thus reducing the net amount of income or gains  available
for distribution to the Fund's shareholders.

Repurchase  Agreements.  Each Fund may  invest in  repurchase  agreements.  In a
repurchase  agreement  the Fund buys a security  for a  relatively  short period
(usually not more than 7 days) subject to the  obligation to sell it back to the
issuer at a fixed time and price  plus  accrued  interest.  Each 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 Funds
enter into repurchase agreements.

Each 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, a decline in
value of the  underlying  securities  or lack of access to  income  during  this
period, and the expense of enforcing its rights.

Reverse Repurchase Agreements.  Each Fund may also enter into reverse repurchase
agreements which involve the sale of 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 a 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. A 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

                                       14

<PAGE>

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.  A Fund will not enter into
reverse  repurchase  agreements and other borrowings  exceeding in the aggregate
more than 33 1/3% of the market  value of its total  assets.  Government  Income
Fund will not make additional  investments while borrowings  (including  reverse
repurchase  agreements)  are in excess of 5% of the Fund's total assets.  A Fund
will enter into reverse repurchase  agreements only with federally insured banks
or  savings  and loan  associations  which  are  approved  in  advance  as being
creditworthy by the Trustees.  Under procedures established by the Trustees, the
Adviser will monitor the creditworthiness of the banks involved.

Restricted Securities. The Funds may purchase securities that are not registered
("restricted  securities")  under  the  Securities  Act of  1933  ("1933  Act"),
including  commercial  paper  issued in reliance on section 4(2) of the 1933 Act
and securities offered and sold to "qualified  institutional  buyers" under Rule
144A under the 1933 Act.  Each Funds will not invest  more than 10% of its total
assets in illiquid  investments,  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 10% limit on illiquid  investments.  The
Trustees may adopt  guidelines and delegate to the Adviser the daily function of
determining and monitoring the liquidity of restricted securities. The Trustees,
however, will retain sufficient oversight and be ultimately  responsible for the
determinations.  The Trustees will carefully monitor each Fund's  investments in
these  securities,   focusing  on  such  important  factors,  among  others,  as
valuation,  liquidity and availability of information.  This investment practice
could  have the  effect  of  increasing  the level of  illiquidity  in a Fund if
qualified  institutional  buyers  become for a time  uninterested  in purchasing
these restricted securities.

Options on Securities,  Securities Indices and Currency.  Each Fund may purchase
and write (sell) call and put options on any  securities in which it may invest,
on any  securities  index based on  securities in which it may invest or, in the
case of High Yield Bond Fund, on any currency in which Fund  investments  may be
denominated.  These  options  may be  listed  on  national  domestic  securities
exchanges  or foreign  securities  exchanges  or traded in the  over-the-counter
market.  Each 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 (in the case of High Yield Bond Fund)  currency,  or to protect
against declines in the value of portfolio  securities and against  increases in
the cost of securities to be acquired.

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

All call and put options written by the Funds are covered. A written call option
or put  option  may be covered  by (i)  maintaining  cash or liquid  securities,
either of which may be quoted or  denominated  in any currency,  in a segregated
account  maintained by the Fund's  custodian  with a value at least equal to the
Fund's  obligation  under the option,  (ii) entering into an offsetting  forward
commitment  and/or (iii)  purchasing  an  offsetting  option or any other option
which,  by virtue of its  exercise  price or  otherwise,  reduces the Fund's net

                                       15

<PAGE>

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. A 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.

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

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

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

The purchase of a put option would  entitle a Fund,  in exchange for the premium
paid, to sell specified  securities or currency 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 a Fund's  portfolio  securities  or (in
the case of High Yield Bond Fund) the currencies in which they are  denominated.
Put options  may also be  purchased  by a Fund for the purpose of  affirmatively
benefiting from a decline in the price of securities or currencies which it does
not own. A Fund would  ordinarily  realize a gain if, during the option  period,
the value of the underlying  securities or currency decreased below the exercise
price  sufficiently  to cover the premium and transaction  costs;  otherwise the
Fund would  realize  either no gain or a loss on the purchase of the put option.
Gains and losses on the purchase of put options may be offset by  countervailing
changes in the value of a Fund's portfolio securities.

Each 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 a 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 a Fund is unable
to effect a closing purchase  transaction with respect to covered options it has
written,  the  Fund  will  not be able  to sell  the  underlying  securities  or
currencies  or dispose of assets held in a segregated  account until the options
expire or are  exercised.  Similarly,  if the Fund is unable to effect a closing
sale  transaction  with  respect to options it has  purchased,  it would have to
exercise  the options in order to realize any profit and will incur  transaction
costs upon the purchase or sale of underlying securities or currencies.

Reasons for the absence of a liquid  secondary market on an exchange include the
following:  (i) there may be insufficient  trading  interest in certain options;
(ii)  restrictions  may be imposed by an  exchange  on opening  transactions  or

                                       16

<PAGE>

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

A 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 or currency markets.

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

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

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

Hedging  and Other  Strategies.  Hedging is an attempt  to  establish  with more
certainty than would otherwise be possible the effective price or rate of return
on portfolio securities or securities that a Fund proposes to acquire or (in the
case of High Yield Bond Fund) the exchange rate of currencies in which portfolio
securities  are  quoted  or  denominated.  When  interest  rates  are  rising or
securities prices are falling,  a 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, a 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.
High  Yield Bond Fund may seek to offset  anticipated  changes in the value of a
currency in which its portfolio  securities,  or  securities  that it intends to

                                       17

<PAGE>

purchase,  are quoted or denominated by purchasing and selling futures contracts
on such currencies.

A Fund may,  for  example,  take a "short"  position  in the  futures  market by
selling futures  contracts in an attempt to hedge against an anticipated rise in
interest  rates or a decline in market prices or (in the case of High Yield Bond
Fund) foreign currency rates that would adversely affect the dollar value of the
Fund's portfolio  securities.  Such futures  contracts may include contracts for
the  future  delivery  of  securities  held  by  the  Fund  or  securities  with
characteristics similar to those of the Fund's portfolio securities.  Similarly,
High Yield Bond Fund may sell futures  contracts on any  currencies in which its
portfolio  securities  are quoted or  denominated  or in one  currency  to hedge
against  fluctuations  in the value of  securities  denominated  in a  different
currency if there is an established  historical  pattern of correlation  between
the two currencies.

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

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

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

Options  on  Futures  Contracts.  Each 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 a 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,  a 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 a Fund's  assets.  By writing a call
option, a 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 a 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 a Fund in writing  options on futures is
potentially unlimited and may exceed the amount of the premium received.

                                       18

<PAGE>

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. A 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.  Each 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 a Fund is using futures and
related options for hedging purposes,  futures contracts will be sold to protect
against a decline in the price of securities  (or the currency in which they are
quoted or denominated) that the Fund owns or futures contracts will be purchased
to protect the Fund against an increase in the price of  securities  (or, in the
case of High  Yield  Bond  Fund,  the  currency  in  which  they are  quoted  or
denominated)  it intends to purchase.  Each 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, each Fund expects that on 75% or more of the occasions on
which it takes a long  futures or option  position  (involving  the  purchase of
futures contracts),  the Fund will have purchased,  or will be in the process of
purchasing,  equivalent  amounts of related  securities (or assets of High Yield
Bond Fund  denominated  in the related  currency) in the cash market at the time
when the futures or option position is closed out. However, in particular cases,
when  it is  economically  advantageous  for a  Fund  to do so,  a long  futures
position may be  terminated  or an option may expire  without the  corresponding
purchase of securities or other assets.

To  the  extent  that a 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.  Each Fund will engage in
transactions  in futures  contracts and related  options only to the extent such
transactions  are consistent with the  requirements of the Internal Revenue Code
of 1986,  as amended  (the  "Code"),  for  maintaining  its  qualification  as a
regulated investment company for federal income tax purposes.

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

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

Perfect  correlation  between a 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 Funds' portfolios are various futures
on U.S. Government securities, securities indices and foreign currencies. In the
event of an  imperfect  correlation  between a futures  position and a portfolio
position  which is intended to be protected,  the desired  protection may not be
obtained  and a Fund may be  exposed  to risk of loss.  In  addition,  it is not
possible to hedge fully or protect against currency  fluctuations  affecting the
value of securities  denominated in foreign currencies because the value of such
securities is likely to fluctuate as a result of independent factors not related
to currency fluctuations.

Some futures  contracts or options on futures may become  illiquid under adverse
market conditions. In addition, during periods of market volatility, a commodity

                                       19

<PAGE>

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 a Fund from  closing  out
positions and limiting its losses.

Restricted Securities. The Funds may purchase securities that are not registered
("restricted  securities")  under  the  Securities  Act of  1933  ("1933  Act"),
including  commercial  paper  issued in reliance on section 4(2) of the 1933 Act
and securities offered and sold to "qualified  institutional  buyers" under Rule
144A under the 1933 Act.  Each Funds will not invest  more than 10% of its total
assets in illiquid  investments,  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 10% limit on illiquid  investments.  The
Trustees may adopt  guidelines and delegate to the Adviser the daily function of
determining and monitoring the liquidity of restricted securities. The Trustees,
however, will retain sufficient oversight and be ultimately  responsible for the
determinations.  The Trustees will carefully monitor each Fund's  investments in
these  securities,   focusing  on  such  important  factors,  among  others,  as
valuation,  liquidity and availability of information.  This investment practice
could  have the  effect  of  increasing  the level of  illiquidity  in a Fund if
qualified  institutional  buyers  become for a time  uninterested  in purchasing
these restricted securities.

Lending of  Securities.  The Funds 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.  A
Fund may reinvest any cash collateral in short-term securities and money markets
funds. When a 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 each Fund not to lend portfolio  securities having a total
value exceeding 30% 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 Fundamental
Investment  Restriction.  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 warrant 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.

Forward Commitment and When-Issued Securities. Each 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.  A  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,  a Fund
contracts  to  purchase  securities  for a fixed  price at a future  date beyond
customary settlement time.

When a 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  Funds  losing  the
opportunity  to obtain a price  and yield  considered  to be  advantageous.  The

                                       20

<PAGE>

purchase  of  securities  on a  when-issued  and forward  commitment  basis also
involves a risk of loss if the value of the  security to be  purchased  declines
prior to the settlement date.

On the date a 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,  a Fund may enter  into
offsetting contracts for the forward sale of other securities that it owns.

Short Term Trading and Portfolio Turnover. Short-term trading means the purchase
and subsequent sale of a security after it has been held for a relatively  brief
period of time. Each Fund may engage in short-term  trading in response to stock
market  conditions,  changes  in  interest  rates or other  economic  trends and
developments,  or to take advantage of yield  disparities  between various fixed
income  securities in order to realize  capital gains or improve  income.  Short
term trading may have the effect of increasing  portfolio  turnover rate. A high
rate of portfolio  turnover (100% or greater) involves  correspondingly  greater
brokerage  transaction  expenses  and may make it more  difficult  for a 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.

INVESTMENT RESTRICTIONS

Fundamental Investment  Restrictions.  Each Fund has adopted certain fundamental
investment  restrictions upon its investments as set forth below which cannot be
changed as to either Fund  without the  approval of the holders of a majority of
that Fund's outstanding shares. A majority for this purpose means: (a) more than
50% of the  outstanding  shares  of a Fund,  or (b)  67% or  more of the  shares
represented at a meeting where more than 50% of the outstanding shares of a Fund
are  represented,  whichever  is less.  If a  percentage  restriction  or rating
restriction  on investment or utilization of assets is adhered to at the time an
investment  is made or assets  are so  utilized,  a later  change in  percentage
resulting from changes in the value of a Fund's portfolio  securities or a later
change in the rating of a portfolio  security will not be considered a violation
of policy.

Each Fund may not:

   
(1) Borrow money in an amount in excess of 33-1/3% of its total assets, and then
only as a temporary measure for extraordinary or emergency purposes (except that
it may enter into a reverse repurchase  agreement within the limits described in
the Prospectus or this Statement of Additional Information), or pledge, mortgage
or  hypothecate an amount of its assets (taken at market value) in excess of 15%
of its total  assets,  in each case taken at the lower of cost or market  value.
For the purpose of this  restriction,  collateral  arrangements  with respect to
options,  futures  contracts,   options  on  futures  contracts  and  collateral
arrangements  with respect to initial and variation margins are not considered a
pledge of assets.
    

(2)  Underwrite  securities  issued by other persons except insofar as such Fund
may  technically  be deemed an  underwriter  under the Securities Act of 1933 in
selling a portfolio security.

(3)  Purchase or retain real estate (including limited partnership interests but
excluding securities of companies,  such as real estate investment trusts, which
deal in real estate or interests therein and securities secured by real estate),
or mineral leases,  commodities or commodity contracts (except contracts for the
future delivery of fixed income securities, stock index and currency futures and
options on such  futures)  in the  ordinary  course of its  business.  Each Fund

                                       21

<PAGE>

reserves  the  freedom  of  action to hold and to sell  real  estate or  mineral
leases, commodities or commodity contracts acquired as a result of the ownership
of securities.

(4)  Invest in  direct  participation  interests  in oil,  gas or other  mineral
exploration or development programs.

(5)  Make loans to other persons  except by the purchase of obligations in which
such Fund is authorized to invest and by entering  into  repurchase  agreements;
provided that a Fund may lend its portfolio  securities  not in excess of 30% of
its total assets  (taken at market  value).  Not more than 10% of a Fund's total
assets (taken at market value) will be subject to repurchase agreements maturing
in more than seven days.  For these purposes the purchase of all or a portion of
an issue of debt securities shall not be considered the making of a loan.

(6)  Purchase  the  securities  of any  issuer  if such  purchase,  at the  time
thereof, would cause more than 5% of its total assets (taken at market value) to
be invested in the securities of such issuer,  other than  securities  issued or
guaranteed by the United States or any state or political  subdivision  thereof,
or any political subdivision of any such state, or any agency or instrumentality
of the  United  States,  any  state or  political  subdivision  thereof,  or any
political  subdivision  of any such state.  In  applying  these  limitations,  a
guarantee  of a security  will not be  considered  a security of the  guarantor,
provided  that  the  value  of all  securities  issued  or  guaranteed  by  that
guarantor,  and owned by the  Fund,  does not  exceed  10% of the  Fund's  total
assets.  In determining the issuer of a security,  each state and each political
subdivision  agency,  and  instrumentality  of each  state and each  multi-state
agency of which such state is a member is a separate  issuer.  Where  securities
are backed only by assets and revenues of a particular instrumentality, facility
or subdivision, such entity is considered the issuer.

(7)  Invest in companies for the purpose of exercising control or management.

(8)  Purchase or retain in its portfolio any securities  issued by an issuer any
of whose  officers,  directors,  trustees or  security  holders is an officer or
Trustee of such  Fund,  or is a member,  partner,  officer  or  Director  of the
Adviser, if after the purchase of the securities of such issuer by such Fund one
or more of such persons owns  beneficially  more than 1/2 of 1% of the shares or
securities, or both, all taken at market value, of such issuer, and such persons
owning  more  than  1/2  of  1%  of  such  shares  or  securities  together  own
beneficially  more than 5% of such shares or  securities,  or both, all taken at
market value.

(9)  Purchase any securities or evidences of interest therein on margin,  except
that each Fund may obtain such  short-term  credit as may be  necessary  for the
clearance of purchases and sales of  securities  and each Fund may make deposits
on margin in connection with futures contracts and related options.

(10) Sell any  security  which  such Fund  does not own  unless by virtue of its
ownership  of other  securities  it has at the  time of sale a right  to  obtain
securities  without  payment of  further  consideration  equivalent  in kind and
amount to the securities sold and provided that if such right is conditional the
sale is made upon equivalent conditions.

(11) Knowingly  invest in securities  which are subject to legal or  contractual
restrictions on resale or for which there is no readily  available market (e.g.,
trading in the security is  suspended or market  makers do not exist or will not
entertain  bids or offers),  except for repurchase  agreements,  if, as a result
thereof more than 10% of such Fund's total assets  (taken at market value) would
be so invested.

(12) Issue any  senior  security  (as that  term is  defined  in the  Investment
Company Act of 1940 (the "1940 Act") if such issuance is specifically prohibited

                                       22

<PAGE>

by the 1940 Act or the rules and  regulations  promulgated  thereunder.  For the
purpose of this  restriction,  collateral  arrangements with respect to options,
futures contracts and options on futures  contracts and collateral  arrangements
with respect to initial and variation  margins are not deemed to be the issuance
of a senior security.

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

Government  Income Fund may not invest more than 25% of its total assets  (taken
at market value) in the securities of issuers engaged in any one industry.  High
Yield  Bond Fund may not  invest  more than 25% of its  total  assets  (taken at
market value) in the securities of issuers  engaged in any one industry,  except
that High Yield Bond Fund may invest up to 40% of the value of its total  assets
in the  securities  of issuers  engaged in the  electric  utility and  telephone
industries.  Obligations  issued or  guaranteed  by the U.S.  Government  or its
agencies or  instrumentalities  are not subject to either Fund's  limitations on
industry  concentration.  Also, a Fund may not purchase securities of any issuer
(other  than  securities  issued or  guaranteed  by the U.S.  Government  or its
agencies or  instrumentalities)  if such  purchase,  at the time thereof,  would
cause a Fund to hold more than 10% of any class of  securities  of such  issuer.
For this purpose,  all  indebtedness of an issuer shall be deemed a single class
and all preferred stock of an issuer shall be deemed a single class.

Government  Income  Fund will not  invest  more  than 5% of its total  assets in
companies which, including their respective predecessors,  have a record of less
than three years' continuous operation.

In order to comply with certain state regulatory policies, neither Fund will, as
a matter of operating  policy,  pledge,  mortgage or  hypothecate  its portfolio
securities if the percentage of securities so pledged, mortgaged or hypothecated
would exceed 15%.

In  order  to  comply  with  certain  state  regulatory  policies,  the  cost of
investments  in options,  financial  futures,  stock index  futures and currency
futures, other than those acquired for hedging purposes, may not exceed 10% of a
Fund's total net assets.

   
Neither Fund may  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  of 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,  each
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 or rating  restriction on investment or utilization
of assets  is  adhered  to at the time an  investment  is made or assets  are so
utilized,  a later change in percentage resulting from changes in the value of a
Fund's  portfolio  securities  or a later  change in the  rating of a  portfolio
security will not be considered a violation of policy.
    

THOSE RESPONSIBLE FOR MANAGEMENT

The business of each Fund is managed by the Trust's  Trustees who elect officers
who are responsible  for the day-to-day  operations of each Fund and who execute
policies formulated by the Trustees. Several of the officers and Trustees of the
Trust are also  officers and  Directors of the Adviser or Officers and Directors
of the Funds'  principal  distributor,  John Hancock Funds,  Inc. ("John Hancock
Funds").

At such date, no other  person(s),  owned of record or was known by the Trust to
beneficially  own as much as 5% of the  outstanding  shares  of the  Trust or of
either of the Funds.

From  December 22, 1994 until  December 22, 1996,  the Trustees  established  an
Advisory  Board to  facilitate a smooth  transition  between  Transamerica  Fund
Management Company ("TFMC"),  the prior investment adviser, and the Adviser. The
members of the Advisory Board were distinct from the Trustees, did not serve the
Funds in any other  capacity and were persons who had no power to determine what
securities were purchased or sold and behalf of the Funds.

Compensation  of the Trustees and Advisory Board.  The following  tables provide
information  regarding  the  compensation  paid  by  the  Funds  and  the  other
investment  companies  in the  John  Hancock  Fund  Complex  to the  Independent
Directors and the Advisory  Board members for their services for the Funds' most
recently  completed fiscal year. Ms. Hodsdon and Messrs.  Boudreau and Scipione,
each a  non-Independent  Trustee,  and each of the  officers  of the  Trust  are
interested  persons of the Adviser,  are  compensated  by the Adviser and/or its
affiliates and receive no compensation from the Funds for their services.

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 Funds 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.
    

Each Fund has entered into an  investment  management  contract with the Adviser
(the "Advisory Agreement"). As manager and investment adviser, 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.

Each Fund bears all cost 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 each Fund's plan of  distribution;  fees and  expenses of  custodian
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  and  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 other wise  affiliated  with the Trust,  the
Adviser or any of their  affiliates;  expenses of  Trustees'  and  shareholders'
meeting;   trade   association   memberships;   insurance   premiums;   and  any
extraordinary expenses.

As provided by the investment management  contracts,  each Fund pays the Adviser
an investment management fee, which is accrued daily and paid monthly in arrears
at the following rates of the Funds' average daily net assets:

John Hancock Government Income Fund
                                                              Fee
Average Daily Net Assets                                 (Annual Rate)
- ------------------------                                 -------------

The first $200 million                                        0.65%
The next $300 million                                         0.625%
Over $500 million                                             0.60%

                                                              Fee
Average Daily Net Assets                                 (Annual Rate)
- ------------------------                                 -------------

The first $75 million                                         0.625%
The next $75 million                                          0.5625%
Over $150 million                                             0.50%

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

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

Pursuant to the investment management  contracts,  the Adviser is not liable for
any error of  judgment  or mistake of law or for any loss  suffered by a Fund in
connection with the matters to which their respective contracts relate, except a
loss resulting from willful  misfeasance,  bad faith or gross  negligence on the
part of the  Adviser  in the  performance  of its  duties  or from its  reckless
disregard  of  the  obligations  and  duties  under  the  applicable  investment
management contract.

Under the  investment  management  contracts,  the Funds may use the name  "John
Hancock"  or any  name  derived  from or  similar  to it only for as long as the
investment  management  contract or any extension,  renewal or amendment thereof
remains in effect.  If a Fund's investment  management  contract is no longer in
effect,  the Fund (to the extent  that it  lawfully  can) will cease to use such
name or any other name indicating  that it is advised by or otherwise  connected
with the  Adviser.  In  addition,  the Adviser or the Life Company may grant the
non-exclusive  right to use the name "John  Hancock" or any similar  name to any
other corporation or entity, including but not limited to any investment company
of which  the  Life  Company  or any  subsidiary  or  affiliate  thereof  or any
successor to the business of any  subsidiary  or affiliate  thereof shall be the
investment adviser.

The continuation of the Advisory  Agreement was approved on June 25, 1996 by all
of the  Trustees.  The  investment  management  contract  and  the  distribution
agreement  discussed  below  continue  in effect  from year to year if  approved
annually by vote of a majority of the Trustees who are not interested persons of
one of the parties to the contract,  cast in person at a meeting  called for the
purpose of voting on such approval, and by either the Trustees or the holders of
a  majority  of  the  Fund's  outstanding  voting  securities.  Both  agreements
automatically terminate upon assignment and may be terminated without penalty on
60  days'  written  notice  by  either  party  or by vote of a  majority  of the
outstanding voting securities of the Fund.

For the period from November 1, 1994 to December 22, 1994 (a) and for the fiscal
year ended October 31, 1994 (b) advisory fees payable by the Funds to TFMC, each
Fund's former investment adviser, were as follows:

                                       34

<PAGE>

         (1)      Government Income Fund - (a) $256,721 and (b) $1,728,997
         (2)      High Yield Bond Fund - (a) $162,374 and (b) $976,834

For the fiscal year ended  October 31, 1996 (a) and for the period from December
22, 1994 to October 31,  1995,  (b)  advisory  fees  payable by the Funds to the
Adviser, were as follows:

         (1)      Government Income Fund -  (a) $3,952,669 and (b) $1,612,806
         (2)      High Yield Bond Fund -    (a) $1,326,701 and (b) $897,349

Administrative  Services  Agreement.  Each  Fund  previously  was a party  to an
administrative services agreement with TFMC (the "Services Agreement"), pursuant
to which TFMC  performed  bookkeeping  and  accounting  services and  functions,
including preparing and maintaining various accounting books,  records and other
documents  and  keeping  such  general  ledgers  and  portfolio  accounts as are
reasonably  necessary  for the  operation  of the  Funds.  Other  administrative
services  included  communications  in response  to  shareholder  inquiries  and
certain printing expenses of various financial reports. In addition,  such staff
and office space,  facilities and equipment was provided as necessary to provide
administrative  services to the Funds.  The  Services  Agreement  was amended in
connection  with the appointment of the Adviser as adviser to the Fund to permit
services  under the Agreement to be provided to the Funds by the Adviser and its
affiliates. The Services Agreement was terminated during the 1995 fiscal year.

The following amounts for each of the Funds for their respective periods reflect
the total of  administrative  services  fees  paid to TFMC ( and to the  Adviser
during the period December 22, 1994 to January 16, 1995):

         Government  Income Fund - For the fiscal  years ended  October 31, 1995
         and 1994 fees paid were $16,694 and $132,786 , respectively.

         High Yield Bond Fund -For the fiscal  years ended  October 31, 1995 and
         1994, fees paid were $13,697 and $100,822.

Accounting and Legal Services  Agreement.  The Trust,  on behalf each Fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this agreement,  the Adviser provides each Fund with certain tax,  accounting
and legal  services.  For the fiscal  year ended  October 31,  1996,  Government
Income Fund and  High-Yield  Bond Fund paid the Adviser  $96,304 and $37,927 for
services under this agreement.

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

DISTRIBUTION CONTRACTS

   
Each Fund has a  Distribution  Agreement  with  John  Hancock  Funds.  Under the
agreement,  John  Hancock  Funds is  obligated  to use its best  efforts to sell
shares of each class of the Fund.  Shares of the Fund are also sold by  selected
broker-dealers  (the "Selling  Brokers')  which have entered into selling agency
agreements  with John Hancock  Funds.  John Hancock Funds accepts orders for the
purchase  of the shares of the Fund which are  continually  offered at net asset
value next determined,  plus an applicable  sales charge,  if any. In connection
with the sale of Class A or Class B  shares,  John  Hancock  Funds  and  Selling
Brokers receive compensation from a sales charge imposed, in the case of Class A
shares,  at the time of sale or, in the case of Class B shares,  on the deferred

                                       35

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.
    

The Distribution  Agreement was initially adopted by the affirmative vote of the
Trust's  Trustees  including  the vote of a  majority  of  Trustees  who are not
parties to the agreement or interested persons of any such party, cast in person
at a meeting called for such purpose. The Distribution  Agreement shall continue
in  effect  from  year to year if  approved  by  either  the vote of the  Fund's
shareholders  or the Trustees  including  the vote of a majority of the Trustees
who are not parties to the  agreement or  interested  persons of any such party,
cast in person at a meeting called for such purpose. The Distribution  Agreement
may be  terminated  at any time as to one or both  Funds,  without  penalty,  by
either party upon sixty (60) days' written  notice or by a vote of a majority of
the  outstanding   voting   securities  of  the  affected  Fund  and  terminates
automatically in the case of an assignment by John Hancock Funds.

For the fiscal year ended October 31, 1996,  the following  amounts  reflect (a)
the total  underwriting  commissions  for sales of the Fund's Class A shares and
(b) the portion of such amount retained by the Fund's distributor,  John Hancock
Funds and the former distributor,  Transamerica Fund Distributors,  Inc. In each
case, the remainder of such underwriting commissions was reallowed to dealers.

         High Yield Bond Fund
         (a) $239,238 and (b) $19,285

         Government Income Fund
         (a) $35,314 and (b) $6,442

Each Fund's  Trustees  adopted  Distribution  Plans with  respect to Class B and
Class B shares (the "Plans") pursuant to Rule 12b-1 under the Investment Company
Act of 1940.

Under  the  Plans , each  Fund's  Class A shares  and  Class B  shares  will pay
distribution  and  service  fees at an  aggregate  annual  rate of up to 25% and
1.00%,  respectively,  of that Fund's 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. In each case, up to 0.25%
is for service expenses and the remaining  amount is for distribution  expenses.
The  distribution  fees will be used to reimburse  John Hancock  Funds for their
distribution  expenses,  including  but not  limited to: (i) initial and ongoing
sales  compensation to Selling Brokers and others (including  affiliates of 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 by used to compensate
Selling  Brokers for  providing  personal  and account  maintenance  services to
shareholders.  In the event the John Hancock.  Funds is not fully reimbursed for
expenses  they incur  under the Class A Plan,  these  expenses  will not 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.  A Fund does not  treat  unreimbursed
expenses under a Class B Plan as a liability of that Fund,  because the Trustees
may terminate a Class B Plan at any time.  For the fiscal year ended October 31,
1996 an aggregate of $9,835,482 of distribution expenses or 5.51% of the average
net assets of  Government  Income  Fund's Class B shares was not  reimbursed  or
recovered by John Hancock Funds through the receipt of deferred sales charges or
Rules  12b-1 fees in prior  periods.  For the same  period,  an  aggregate  of $
7,642,995  of  distribution  expenses or 3.83% of the average net assets of High
Yield Bond Fund's Class B shares 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 each Fund. The
Plans and all amendments were approved by the Trustees,  including a majority of
the Trustees who are not interested  persons of each Fund and who have no direct
or indirect  financial interest in the operation of the Plans ( the "Independent
Trustees"), by votes cast in person at meetings called for the purpose of voting
on such Plans.

Pursuant to the Plans, at least quarterly,  John Hancock Funds provide each 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.

Each  Plan  provide  that  they will  continue  in effect  only so long as their
continuance is approved at least annually by a majority of both the Trustees and
Independent  Trustees.  Each Plan provides  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 that Fund's  outstanding  shares of the  applicable  class upon 60
days' written notice to John Hancock Funds,  and (c)  automatically in the event
of  assignment.  The  plans  further  provide  that they may not be  amended  to
increase  the  maximum  amount of the fees for the  services  described  therein
without the approval of a majority of the outstanding shares of the class of the
Fund which has voting  rights to that Plan.  Each of the 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,  these is a reasonable
likelihood  that the Plans will benefit the holders of the  applicable  class of
shares of affected Fund.

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

During the fiscal year ended October 31, 1996,  the Funds paid the  Distributors
the following amounts of expenses with respect to the Class A shares and Class B
shares of each of the Funds:

NET ASSET VALUE

For  purposes of  calculating  the net asset value  ("NAV") of the shares of the
Funds, 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.

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

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

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 the 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 for each fund and class is determined  each business day at the close of
regular  trading on the New York Stock  Exchange  (typically  4:00 p.m.  Eastern
Time) by dividing a class 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 Funds are offered at a price equal to their net asset value plus a
sales charge which, at the option of the purchaser, may be imposed either at the
time of purchase (the  "initial  sales charge  alternative")  or on a contingent
deferred basis (the "deferred  sales charge  alternative").  Share  certificates
will not be issued unless requested by the shareholder in writing, and then only
will be issued for full  shares.  The Trustees of each Fund reserve the right to
change or waive each 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 respective Fund's best interest.

The sales  charges  applicable  to  purchases of Class A shares of the Funds are
described in the Prospectus. Methods of obtaining reduced sales charges referred
to generally in the Prospectus are described in detail below. In calculating the
sales charge applicable to current purchases of Class A shares,  the investor is
entitled to accumulate  current  purchases with the greater of the current value

                                       38

<PAGE>

(at offering  price) of the Class A shares of the Funds,  owned by the investor,
or if John Hancock Signature Services,  Inc. ("Signature  Services") is notified
by the investor's  dealer or the investor at the time of the purchase,  the cost
of the Class A shares owned.

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

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

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

o        A Trustee or officer of the Trust; a Director or officer of the Adviser
         and  its   affiliates   or   Selling   Brokers;   employees   or  sales
         representatives of any of the foregoing; retired officers, employees or
         Directors of any of the  foregoing;  a member of the  immediate  family
         (spouse,  children,  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 of 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,  for each Fund, if the
         shares are redeemed within 12 months after the end of the calendar year
         in which the purchase was made, a CDSC will be imposed at the following
         rate:

         Amount Invested                                            CDSC Rate
         ---------------                                            ---------

         $1 to $4,999,999                                             1.00%
         Next $5 million to $9,999,999                                0.50%
         Amounts of $10 million and over                              0.25%
    
                                       39

<PAGE>

   
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.

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.  Each 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 with the specified period (either 13 or
48 months), the sales charge applicable will not be higher than that which would
have been applied  (including  accumulations  and combinations) had the LOI been
for the amount actually invested.

The LOI  authorizes  Signature  Services  to hold in escrow  sufficient  Class A
shares  (approximately  5% of the  aggregate) to make up any difference in sales
charges on the amount intended to be invested and the amount actually  invested,
until such investment is completed  within the specified  period,  at which time
the escrow 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

                                       40

<PAGE>

proceeds  used as required  to pay such sales  charges as may be due. By signing
the  LOI,   the   investor   authorizes   Signature   Services  to  act  as  his
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 a Fund to sell,  any  additional  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 a sales  charge so the Funds 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  purchase  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 share 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

                                       41

<PAGE>

         (40 shares X $2)                                               -  80
                                                                        -----
*        Amount subject to CDSC                                         $ 400

Proceeds  from the CDSC are paid to John Hancock  Funds and are used in whole or
in part by John  Hancock  Funds to defray  its  expenses  related  to  providing
distribution-related  services  to the Fund in  connection  with the sale of the
Class B shares,  such as the payment of  compensation  to select Selling Brokers
for selling Class B shares. The combination of the CDSC and the distribution and
service  fees  facilitates  the  ability of the Funds 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 a CDSC,
unless indicated otherwise, in the circumstances defined below:

For all account types:

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

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

*        Redemptions due to death or disability.

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

         401(a)  of the Code  (such as  401(k),  Money  Purchase  Pension  Plan,
         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  the Funds would not normally do so, each Fund has the right to pay the
redemption  price  of  shares  of the  Fund in  whole  or in  part in  portfolio
securities as prescribed by the Trustees.  When the shareholder  sells portfolio
securities  received in this  fashion,  the  shareholder  will incur a brokerage
charge. Any such security would be valued for the purpose of making such payment
at the same value as used in determining  the Fund's net asset value.  Each Fund
has however  elected to be governed by Rule 18f-1 under the  Investment  Company
Act.  Under that rule, the Funds must redeem their shares for cash except to the
extent to that the  redemption  payments  to any  shareholder  during any 90-day
period  would exceed the lesser of $250,000 or 1% of the  applicable  Fund's net
asset value at the beginning of such period.

ADDITIONAL SERVICES AND PROGRAMS

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

Exchanges  between funds with shares that are not subject to a CDSC are based on
their  respective net asset values.  No sales charge or  transactions  charge is
imposed.  Shares of the Fund which are subject to a CDSC may be  exchanged  into
shares of any of the other John Hancock funds that are subject to a CDSC without
incurring the CDSC; however,  the shares acquired in an exchange will be subject
to the CDSC schedule of the shares acquired if and when such shares are redeemed
(except that shares  exchanged  into John Hancock  Short-Term  Strategic  Income
Fund,  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.

Each 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.

Each Fund may  refuse  any  exchange  order.  Each 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. Each Fund permits the establishment of a Systematic
Withdrawal Plan. Payments under this plan represent proceeds from the redemption
of shares of the applicable  Fund. Since the redemption price of the shares of a
Fund may be more or less than the shareholder's cost,  depending upon the market
value of the  securities  owned  by each  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 Funds could be disadvantageous to a shareholder because of
the initial  sales  charge  payable on such  purchases of Class A shares and the
CDSC  imposed on  redemptions  of Class B shares  and  because  redemptions  are
taxable events.  Therefore, a shareholder should not purchase Class A or Class B

                                       44

<PAGE>

shares at the same time a  Systematic  Withdrawal  Plan is in effect.  The Funds
reserve 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 due date of any investment.

Reinstatement  and  Reinvestment  Privilege.  If Signature  Services is notified
prior to  reinvestment,  a shareholder  who has redeemed each Fund's 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
each 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
each 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 each Fund,  each Fund may cancel
the reinvestment privilege of any parties that, in the opinion of the Funds, are
using market timing  strategies or making more than seven exchanges per owner or
controlling party per calendar year. Also, the Funds may refuse any reinvestment
request.

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

Class A and  Class B  shares  of each  Fund  represent  an  equal  proportionate
interest in the  aggregate net asset values  attributable  to that class of each
Fund. Holders of Class A shares and Class B shares have certain exclusive voting
rights  on  matters  relating  to the  Class  A  Plan  and  the  Class  B  Plan,
respectively,  of the applicable  Fund.  The different  classes of the Funds 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 Funds,  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  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 shares and Class B shares  will bear any class
expenses properly  allocable to such class of shares,  subject to the conditions
the Internal Revenue Service imposes with respect to multiple-class  structures.
Similarly,  the net asset  value per  share may vary  depending  on the class of
shares purchased.

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 in a majority of the Trustees holding office
were elected by the  shareholders,  the Trustees will call a special  meeting of
shareholders for the purpose of electing Trustees.

Under Massachusetts law,  shareholders of a Massachusetts  business trust could,
under certain  circumstances,  be held personally liable for acts or obligations
of the trust.  However,  the Trust's  Declaration  of Trust  contains an express
disclaimer of  shareholder  liability for acts,  obligations  and affairs of the
Trust.  The  Declaration of Trust also provides for  indemnification  out of the
Trust's assets for all losses and expenses of any  shareholder  held  personally
liable by reason of being or having been a shareholder. The Declaration of Trust
also provides that no series of the Trust shall be liable for the liabilities of
any other series.  Liability is therefore  limited to circumstances in which the
Trust itself would be unable to meet its  obligations,  and the  possibility  of
this occurrence is remote.

TAX STATUS

Each Fund is treated as a separate entity for accounting and tax purposes.  Each
Fund has qualified and elected to be treated as a "regulated investment company"
under  Subchapter M of the Code,  and intends to continue to so qualify for each
taxable year.  As such and by complying  with the  applicable  provisions of the
Code regarding the sources of its income, the timing of its  distributions,  and
the  diversification  of its  assets,  each Fund will not be  subject to Federal
income tax on taxable  income  (including  net realized  capital gains) which is
distributed to shareholders  in accordance  with the timing  requirements of the
Code.

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

Distributions from a Fund's current or accumulated  earnings and profits ("E&P")
will be taxable  under the Code for  investors  who are subject to tax. If these
distributions are paid from the Fund's "investment company taxable income," they
will be taxable as  ordinary  income;  and if they are paid from the Fund's "net
capital gain," they will be taxable as long-term  capital gain (net capital gain
is the excess (if any) of net long-term capital gain over net short-term capital
loss,  and investment  company  taxable income is all taxable income and capital
gains,  other than net capital gain,  after  reduction by deductible  expenses).
Some  distributions  from  investment  company taxable income and/or net capital
gain may be paid in January  but may be taxable to  shareholders  as if they had
been received on December 31 of the previous year.  Neither Fund's  dividends or
other distributions will generally qualify for the dividends-received  deduction
available to corporations.  The tax treatment described above will apply without
regard to whether distributions are received in cash or reinvested in additional
shares of the Fund.

Distributions,  if any,  in excess of E&P will  constitute  a return of  capital
under the Code, which will first reduce an investor's  federal tax basis in Fund
shares and then, to the extent such basis is exceeded,  will generally give rise
to capital gains.  Shareholders who have chosen automatic  reinvestment of their
distributions  will have a federal tax basis in each share received  pursuant to
such a  reinvestment  equal to the amount of cash they would have  received  had
they  elected  to receive  the  distribution  in cash,  divided by the number of
shares received in the reinvestment.

Foreign exchange gains and losses realized by High Yield Bond Fund in connection
with  certain   transactions   involving   foreign   currency-denominated   debt
securities,  certain  foreign  currency  futures and options,  foreign  currency
forward contracts, foreign currencies, or payables or receivables denominated in
a foreign  currency  are  subject to Section  988 of the Code,  which  generally
causes such gains and losses to be treated as ordinary income and losses and may
affect the amount,  timing and character of distributions  to shareholders.  Any
such  transactions that are not directly related to a Fund's investment in stock
or securities,  possibly  including  speculative  currency positions or currency
derivatives not used for hedging purposes, may increase the amount of gain it is
deemed to recognize from the sale of certain investments or derivatives held for
less than three months, which gain is limited under the Code to less than 30% of
gross income for each taxable year, and could under future Treasury  regulations
produce  income not among the types of  "qualifying  income" from which the Fund
must derive at least 90% of its gross income for each taxable  year.  If the net
foreign exchange loss for a year treated as ordinary loss under Section 988 were

                                       47

<PAGE>

to exceed a Fund's investment  company taxable income computed without regard to
such loss but after  considering the post-October loss regulations the resulting
overall  ordinary  loss for such year would not be deductible by the Fund or its
shareholders in future years.

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

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

High Yield Bond Fund is permitted to acquire stock in foreign  corporations.  If
this Fund acquires stock of certain foreign  corporations  that receive at least
75% of their  annual  gross  income  from  passive  sources  (such as  interest,
dividends,  rents,  royalties  or  capital  gain) or hold at least  50% of their
assets in investments producing such passive income ("passive foreign investment
companies"),  the Fund could be subject  to  federal  income tax and  additional
interest charges on "excess distributions"  received from such companies or gain
from the sale of stock in such  companies,  even if all income or gain  actually
received by the Fund is timely  distributed to its shareholders.  The Fund would
not be able to pass through to its shareholders any credit or deduction for such
a tax.  Certain  elections  may,  if  available,  ameliorate  these  adverse tax
consequences,  but any such election would require the Fund to recognize taxable
income or gain without the concurrent receipt of cash. The Fund may limit and/or
manage its holdings in passive foreign investment  companies to minimize its tax
liability or maximize its return from these investments.

The amount of a Fund's net  realized  capital  gains,  if any, in any given year
will vary depending upon the Adviser's current  investment  strategy and whether
the Adviser  believes  it to be in the best  interest of such Fund to dispose of
portfolio  securities  or enter into options or futures  transactions  that will
generate capital gains. At the time of an investor's  purchase of Fund shares, a
portion of the purchase  price is often  attributable  to realized or unrealized
appreciation in the Fund's  portfolio.  Consequently,  subsequent  distributions
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

                                       48

<PAGE>

below the  investor's  cost for such shares,  and the  distributions  in reality
represent a return of a portion of the purchase price.

Upon a  redemption  of shares of a Fund  (including  by exercise of the exchange
privilege) a shareholder  may realize a taxable gain or loss  depending upon the
amount of the proceeds and the investor's basis in his shares.  Any gain or loss
will be treated as capital gain or loss if the shares are capital  assets in the
shareholder's  hands and will be long-term  or  short-term,  depending  upon the
shareholder's tax holding period for the shares and subject to the special rules
described  below.  A sales  charge paid in  purchasing  Class A shares of a Fund
cannot be taken into  account for  purposes of  determining  gain or loss on the
redemption or exchange of such shares within 90 days after their purchase to the
extent shares of the Fund or another John Hancock fund are subsequently acquired
without  payment of a sales  charge  pursuant  to the  reinvestment  or exchange
privilege. Such disregarded load 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 same  Fund  within a period of 61 days
beginning  30 days before and ending 30 days after the shares are  disposed  of,
such as pursuant to automatic dividend reinvestments.  In such a case, the basis
of the shares acquired will be adjusted to reflect the disallowed loss. Any loss
realized upon the  redemption of shares with a tax holding  period of six months
or less will be treated as a long-term capital loss to the extent of any amounts
treated as distributions of long-term capital gain with respect to such shares.

Although its present  intention is to  distribute,  at least  annually,  all net
capital gain, if any, each 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 Funds
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 by the Fund, each
shareholder  would be treated for Federal income tax purposes as if the Fund had
distributed  to him on the last day of its  taxable  year his pro rata  share of
such  excess,  and he had paid his pro rata  share of the taxes paid by the Fund
and reinvested the remainder in the Fund.  Accordingly,  each shareholder  would
(a) include his pro rata share of such excess as  long-term  capital gain income
in his return for his taxable year in which the last day of such 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 such  Fund,  and (c) be
entitled to increase  the  adjusted tax basis for his shares in such Fund by the
difference  between  his pro rata share of such excess and his pro rata share of
such taxes.

For Federal  income tax  purposes,  each Fund is  generally  permitted  to carry
forward a net capital loss in any year to offset its own net capital  gains,  if
any,  during  the eight  years  following  the year of the loss.  To the  extent
subsequent net capital gains are offset by such losses, they would not result in
Federal income tax liability to the applicable  Fund and, as noted above,  would
not be distributed as such to shareholders.  As of December 31, 1996, High Yield
Bond Fund had capital loss  carryforwards  of $20,457,110,  of which  $9,184,152
expires in 2002 and $11,272,858  expires in 2003, and Government Income Fund had
capital loss  carryforwards of $16,766,596 of which $15,347,195  expires in 2002
and $1,419,401 expires in 2003. All of the capital loss  carryforwards  expiring
in 1996, 1997, 2000 and 2001, respectively, were acquired on September 15, 1995,
in the  reorganization  with  John  Hancock  Government  Securities  Trust  and,
consequently, their availability may be limited under the Code in a given year.

A Fund is required to accrue income on any debt securities that have more than a
de minimis 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,  futures and forward  contracts may
also require the Fund to recognize  income or gain without a concurrent  receipt

                                       49

<PAGE>

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
may have to leverage itself by borrowing the cash, to satisfy these distribution
requirements.

A state  income (and  possibly  local income  and/or  intangible  property)  tax
exemption is generally  available to the extent (if any) a Fund's  distributions
are derived from interest on (or, in the case of intangibles 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 Funds will not seek to satisfy any
threshold  or  reporting  requirements  that  may  apply  in  particular  taxing
jurisdictions,  although either Fund may in its sole discretion provide relevant
information to shareholders.

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

Investments in debt  obligations  that are at risk of or are in default  present
special tax issues for the Funds.  Tax rules are not entirely clear about issues
such as when the Funds 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 a Fund that holds such  obligations  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 Funds
may restrict a Fund's ability to enter into futures,  options,  foreign currency
positions and currency forward transactions.

Certain options, futures and forward foreign currency transactions undertaken by
a Fund may cause such Fund to  recognize  gains or losses from marking to market
even  though  its  positions  have not been sold or  terminated  and  affect the
character  as  long-term  or  short-term  (or,  in the case of certain  currency
forwards,  options and futures,  as ordinary  income or loss) and timing of some
capital gains and losses realized by the Fund. Also,  certain of a Fund's losses
on its  transactions  involving  options,  futures and forward foreign  currency
contracts  and/or  offsetting or successor  portfolio  positions may be deferred
rather than being taken into account currently in calculating the Fund's taxable
income or gains.  Certain of such  transactions may also cause a Fund to dispose
of investments sooner than would otherwise have occurred. These transactions may
therefore affect the amount,  timing and character of a Fund's  distributions to
shareholders. Certain of the applicable tax rules may be modified if the Fund is

                                       50

<PAGE>

eligible  and chooses to make one or more of certain tax  elections  that may be
available.  The Funds will take into  account the  special tax rules  (including
consideration of available elections) applicable to options,  futures or forward
contracts in order to seek to minimize any potential adverse tax consequences.

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  foregoing  discussion  relates  solely to U.S.  Federal  income  tax law as
applicable to U.S. persons (i.e.,  U.S.  citizens or residents and U.S. domestic
corporations,  partnerships,  trusts or estates)  subject to tax under such law.
The discussion does not address special tax rules  applicable to certain classes
of investors,  such as tax-exempt entities,  insurance companies,  and financial
institutions.  Dividends, capital gain distributions,  and ownership of or gains
realized on the  redemption  (including  an exchange) of Fund shares may also be
subject to state and local  taxes.  Shareholders  should  consult  their own tax
advisers as to the  Federal,  state or local tax  consequences  of  ownership of
shares  of,  and  receipt  of  distributions  from,  a Fund in their  particular
circumstances.

Non-U.S.  investors  not engaged in a U.S.  trade or  business  with which their
investment in a Fund is effectively  connected  will be subject to U.S.  Federal
income  tax  treatment  that is  different  from  that  described  above.  These
investors may be subject to nonresident alien withholding tax at the rate of 30%
(or a lower rate under an applicable tax treaty) on amounts  treated as ordinary
dividends  from a Fund  and,  unless  an  effective  IRS Form W-8 or  authorized
substitute  for Form W-8 is on file, to 31% backup  withholding on certain other
payments from the Fund.  Non-U.S.  investors  should  consult their tax advisers
regarding such  treatment and the  application of foreign taxes to an investment
in the Funds.

The Funds are not subject to Massachusetts  corporate excise or franchise taxes.
Provided that each 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

   
Yield.  For the 30-day period ended April 30, 1997, the yields of (a) High Yield
Bond Fund's Class A and Class B shares were 9.92% and 9.63%,  respectively,  and
(b)  Government  Income Fund's Class A and Class B shares were 5.92% and 5.45 %,
respectively.

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

                                                    6 
                        Yeild = 2 ( [ (a - b) + 1 ]   - 1 )


Where:

         a =      dividends and interest earned during the period.

         b =      net expenses accrued during the period.

                                       51
<PAGE>

         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.  Average  annual total return is determined  separately  for each
class of shares.

Set forth  below are tables  showing the  performance  on a total  return  basis
(i.e., with all dividends and distributions reinvested) of a hypothetical $1,000
investment in the Class A and Class B shares of Government  Income Fund and High
Yield Bond Fund.

</TABLE>

*        Commencement of operations.

Total Return. Each Fund's total return is computed by finding the average annual
compounded  rate of return over the 1-year,  5-year,  and 10-year  periods  that
would  equate  the  initial  amount  invested  to the  ending  redeemable  value
according to the following formula:
    

     n _____
T = \ /ERV/P - 1


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

         T =       average annual total return.

         n =       number of years.

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

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

                                       52
<PAGE>

The total  return in the case of Class B shares  of each Fund is  calculated  by
determining  the net asset value of all shares held at the end of the period for
each share held from the beginning of the period  (assuming  reinvestment of all
dividends  and  distributions  at net asset  value  during  the  period  and the
deduction of any  applicable  contingent  deferred sales charge as if the shares
were redeemed at the end of the period),  subtracting the maximum offering price
per share (net asset value per share) at the  beginning  of such period and then
dividing the result by the maximum offering price per share (net asset value per
share) at the  beginning of the same period.  Total return for Class A shares of
each of  Government  Income Fund and High Yield Bond Fund is  calculated  in the
same manner  except the maximum  offering  price  reflects the  deduction of the
maximum initial sales charge and the redemption value is at net asset value.

In addition to average  annual total  returns,  a Fund may quote  unaveraged  or
cumulative total returns  reflecting the simple change in value of an investment
over a stated period.  Cumulative total returns may be quoted as a percentage or
as a dollar amount, and may be calculated for a single  investment,  a series of
investments, and/or a series of redemptions, over any time period. Total returns
may be quoted with or without  taking the Fund's maximum sales charge on Class A
shares or the CDSC on Class B shares into account. A Fund's  "distribution rate"
is determined by  annualizing  the result of dividing the declared  dividends of
the Fund  during the stated  period by the maximum  offering  price or net asset
value at the end of the  period.  Excluding  a 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,  a Fund's yield and
total  return  will be  compared  to  indices of mutual  funds and bank  deposit
vehicles such as Lipper Analytical Services,  Inc.'s  "Lipper--Fixed Income Fund
Performance  Analysis," a monthly  publication  which  tracks net assets,  total
return,  and yield on fixed income mutual funds in the United  States.  Ibottson
and Associates,  CDA  Weisenberger  and F.C. Towers are also used for comparison
purposes, as well as the Russell and Wilshire Indices.

Performance  rankings and ratings  reported  periodically in national  financial
publications  such as MONEY  MAGAZINE,  FORBES,  BUSINESS  WEEK, THE WALL STREET
JOURNAL, MICROPAL, INC., MORNINGSTAR,  STANGER'S and BARRON'S, etc. will also be
utilized.  A Fund's  promotional and sales  literature may make reference to the
Fund's "beta." Beta reflects the market-related  risk of the Fund by showing how
responsive the Fund is to the market.

The  performance  of a Fund is not fixed or guaranteed.  Performance  quotations
should not be considered to be  representations of performance of a Fund for any
period in the future.  The  performance  of a 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 a 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 and officers of the
Trust  pursuant  to  recommendations  made by its  investment  committee,  which
consists of officers and  directors of the Advisor and  affiliates  and officers
and Trustees who are interested  persons of the Funds.  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."  Investments in debt securities are generally  traded
on a net basis through  dealers  acting for their own account as principals  and
not as brokers; no brokerage commissions are payable on such transactions.

                                       53

<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.  In other  countries,  both  debt and  equity
securities  are traded on exchanges at fixed  commission  rates.  commissions on
foreign  transactions are generally higher than the negotiated  commission rates
available  in the U.S.  There  is  generally  less  government  supervision  and
regulation of foreign stock exchanges and broker-dealers than in the U.S.

Each 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 NASD and other  policies  that the  Trustees  may
determine,  the Adviser may consider sales of shares of the Funds as a factor in
the selection of broker-dealers to execute a Fund's portfolio transactions.

To the extent  consistent with the foregoing,  each Fund will be governed in the
selection of brokers and dealers,  and the  negotiation of brokerage  commission
rates and dealer  spreads,  by the  reliability  and  quality  of the  services,
including primarily the availability and value of research  information and to a
lesser extent statistical  assistance  furnished to the Adviser of the Fund, and
their value and expected  contribution to the performance of the Fund. It is not
possible to place a dollar value on information and services to be received from
brokers and dealers,  since it is only  supplementary to the research efforts of
the  Adviser.  The receipt of  research  information  is not  expected to reduce
significantly  the  expenses  of  the  Adviser.  The  research  information  and
statistical  assistance  furnished  by brokers  and dealers may benefit the Life
Company or other  advisory  clients of the Adviser,  and  conversely,  brokerage
commissions and spreads paid by other advisory clients of the Adviser may result
in research information and statistical  assistance beneficial to the Funds. The
Funds will make no  commitments  to  allocate  portfolio  transactions  upon any
prescribed basis. While the Adviser's officers will be primarily responsible for
the allocation of each Fund's brokerage business,  the policies and practices of
the Adviser in this regard must be consistent with the foregoing and will at all
times be subject to review by the Trustees.

Brokerage  commissions of the Funds for their respective  reporting periods,  as
follows, amounted to:

         Government Income Fund - (a) $135,622 for the fiscal year ended October
         31, 1996;  (b) $15,814 for the fiscal year ended October 31, 1995;  (c)
         $96,931 for the fiscal year ended October 31, 1994.

         High Yield Bond Fund - (a) $ 39,163 for the fiscal  year ended  October
         31, 1996 (b) $40,228 for the fiscal year ended October 31, 1995 and (c)
         $2,320 for the fiscal year ended October 31,1994.

As permitted by Section 28(e) of the Securities  Exchange Act of 1934, each Fund
may pay to a broker which provides  brokerage and research  services to the Fund
an amount of disclosed  commission  in excess of the  commission  which  another
broker would have  charged for  effecting  that  transaction.  This  practice is
subject  to a good  faith  determination  by the  Trustees  that  the  price  is
reasonable  in light of the services  provided and to policies that the Trustees
may adopt from time to time.  During the fiscal  year ended  October  31,  1996,
Government Income Fund paid $405 and High Yield Bond Fund paid $0 in commissions
to  compensate  brokers for research  services  such as  industry,  economic and
company reviews and evaluations of securities.

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

                                       54

<PAGE>

execute  portfolio  transactions  with or through  Affiliated  Brokers.  For the
fiscal year ended October 31, 1996,  the Fund paid no Brokerage  commissions  to
any Affiliated Broker.

Distributors  may act as broker for a 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  1940  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 a Fund as determined by a majority of the
Trustees  who are not  "interested  persons" (as defined in the 1940 Act) of the
Funds,  the Adviser or the  Affiliated  Brokers.  Because the Adviser,  which is
affiliated  with the Affiliated  Brokers,  has, as an investment  adviser to the
Fund, the obligation to provide investment  management services,  which includes
elements of research and related  investment  skills,  such research and related
skills  will not be used by the  Affiliated  Brokers as a basis for  negotiating
commissions at a rate higher than that  determined in accordance  with the above
criteria.

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

                                   APPENDIX A

            DESCRIPTION OF BOND RATINGS AND FUND'S ASSET COMPOSITION

The ratings of Moody's  Investors  Service,  Inc. and Standard & Poor's  Ratings
Group  represent  their  opinions as to the quality of various debt  instruments
they  undertake to rate. It should be  emphasized  that ratings are not absolute
standards of quality.  Consequently,  debt  instruments  with the same maturity,
coupon and rating may have different  yields while debt  instruments of the same
maturity and coupon with different ratings may have the same yield.

                         MOODY'S INVESTORS SERVICE, INC.

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

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

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

Baa: 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.

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

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

Caa:  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.

Ca: 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.

                         STANDARD & POOR'S RATINGS GROUP

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

                                       A-1

<PAGE>

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

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

BBB:  Debt rated BBB is regarded as having 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:  Debt  rated  BB,  and  B 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 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.

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.

                        FITCH INVESTORS SERVICE ("Fitch")

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

                             TAX-EXEMPT NOTE RATINGS

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

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

                                       A-2

<PAGE>

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

                CORPORATE AND TAX-EXEMPT COMMERCIAL PAPER RATINGS

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

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

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

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

ORGANIZATION OF THE TRUST

   
The Fund is a series of the Trust,  an open-end  investment  management  company
organized as a Massachusetts  business trust under the laws of The  Commonwealth
of Massachusetts.  Prior to September 22, 1995, the Fund was called John Hancock
Adjustable  U.S.  Government  Trust.  Prior to December 22,  1994,  the Fund was

INVESTMENT OBJECTIVE AND POLICIES

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

The  Fund  seeks  to  earn a high  level  of  current  income,  consistent  with
preservation of capital and maintenance of liquidity.  The Fund seeks to achieve
its investment  objective by investing primarily in U.S. Government  securities,
including  mortgage-backed  securities  issued or guaranteed by U.S.  Government
agencies. Since the U.S. Government has never defaulted on its obligations,  its
securities are considered  unmatched as a safe and reliable  income source.  The
Fund may also invest in  obligations of the Tennessee  Valley  Authority and the
World Bank and  medium-term  debt  obligations of  governmental  issuers.  Under
normal  market  conditions,  the Fund  intends to  maintain  a weighted  average
remaining maturity or average remaining life of three to ten years.

Under normal conditions, at least 65% of the Fund's total assets will be in U.S.
Government securities that consist of the following:

1.       U.S. Treasury  obligations,  which differ only in their interest rates,
maturities and time of issuance,  including U.S. Treasury bills (maturity of one
year or less),  U.S.  Treasury  notes  (maturity of one to ten years),  and U.S.
Treasury bonds (generally maturities greater than ten years); and

2.       Obligations issued or guaranteed by the U.S.  Government,  its agencies
or  instrumentalities  which are  supported by: (i) the full faith and credit of
the U.S. Government (e.g., securities issued by the Government National Mortgage
Association ("GNMA")),  (ii) the right of the issuer to borrow an amount limited
to a specific line of credit from the U.S.  Government (e.g.,  securities of the
Federal Home Loan Bank Board) or (iii) the credit of the instrumentality  (e.g.,
bonds issued by the Federal Home Loan Mortgage Association  ("FHLMC") or Federal
National Mortgage Association ("FNMA").

In general,  investments in shorter and  intermediate  term (three to ten years)
debt  securities  are less  sensitive to interest  rate changes and provide more
stability than longer-term (ten years or more)  investments.  Shares of the Fund
are not  deposits or  obligations  of, or  guaranteed  or endorsed by, any bank.
Also,  Fund shares are not federally  insured by the Federal  Deposit  Insurance
Corporation,  the Federal  Reserve  Board or any other  government  agency.  All

                                       2

<PAGE>

temporary  defensive  investments  are required to be high quality.  There is no
assurance that the Fund will achieve its investment objective.

Ratings as Investment  Criteria.  In general,  the ratings of Moody's  Investors
Service, Inc. ("Moody's") and Standard & Poor's Ratings Group ("S&P") represents
the  opinions of these  agencies as to the quality of the  securities  that 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 that 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.

Structured  Securities.  The Fund may invest 10% of its net assets 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.

Mortgage  Backed  Securities.  The  Fund may  invest  in  mortgage  pass-through
certificates and  multiple-class  pass-through  securities,  such as real estate
mortgage investment conduits ("REMIC") pass-through certificates, collateralized
mortgage obligations ("CMOs") and stripped mortgage-backed  securities ("SMBS"),
and other types of  "Mortgage-Backed  Securities"  that may be  available in the
future.
    

Guaranteed Mortgage  Pass-Through  Securities.  Guaranteed mortgage pass-through
securities  represent  participation  interests in pools of residential mortgage
loans and are issued by U.S.  Governmental  or private lenders and guaranteed by
the U.S. Government or one of its agencies or  instrumentalities,  including but
not  limited to the  Government  National  Mortgage  Association  ("GNMA"),  the
Federal  National  Mortgage  Association  ("FNMA")  and the  Federal  Home  Loan
Mortgage  Corporation  ("FHLMC").  GNMA  certificates are guaranteed by the full
faith and credit of the U.S.  Government  for timely  payment of  principal  and
interest on the  certificates.  FNMA  certificates  are  guaranteed  by FNMA,  a
federally chartered and privately owned corporation, for full and timely payment
of principal and interest on the certificates. FHLMC certificates are guaranteed
by FHLMC, a corporate instrumentality of the U.S. Government, for timely payment
of interest and the ultimate collection of all principal of the related mortgage
loans.

Multiple-Class  Pass-Through Securities and Collateralized Mortgage Obligations.
CMOs and REMIC  pass-through  or  participation  certificates  may be issued by,
among others, U.S. Government agencies and  instrumentalities as well as private
lenders.  CMOs and REMIC  certificates  are issued in  multiple  classes and the
principal  of and interest on the  mortgage  assets may be  allocated  among the
several  classes of CMOs or REMIC  certificates  in various ways.  Each class of
CMOs or REMIC  certificates,  often  referred to as a "tranche,"  is issued at a
specific  adjustable  or fixed  interest rate and must be fully retired no later
than its final distribution date. Generally,  interest is paid or accrues on all
classes of CMOs or REMIC certificates on a monthly basis.

Typically,  CMOs are collateralized by GNMA, FNMA or FHLMC certificates but also
may be  collateralized  by other mortgage  assets such as whole loans or private
mortgage pass-through securities. Debt service on CMOs is provided from payments
of principal and interest on collateral of mortgaged assets and any reinvestment
income thereon.

A REMIC is a CMO that  qualifies  for special tax  treatment  under the Internal
Revenue Code of 1986,  as amended (the "Code") and invests in certain  mortgages
primarily secured by interests in real property and other permitted investments.
Investors may purchase "regular" or "residual" interest in REMICS,  although the
Fund does not intend,  absent a change in current tax law, to invest in residual
interests.

Stripped  Mortgage-Backed   Securities.   SMBS  are  derivative   multiple-class
mortgage-backed  securities.  SMBS are usually  structured with two classes that
receive different proportions of interest and principal  distributions on a pool
of mortgage  assets.  A typical SMBS will have one class  receiving  some of the
interest and most of the  principal,  while the other class will receive most of
the interest and the remaining  principal.  In the most extreme case,  one class
will receive all of the  interest  (the  "interest  only" class) while the other
class will receive all of the principal (the "principal only" class). The yields
and market risk of interest only and principal only SMBS,  respectively,  may be
more  volatile  than those of other fixed  income  securities.  The staff of the
Securities and Exchange Commission ("SEC") considers privately issued SMBS to be
illiquid.

Risk  Factors   Associated  with   Mortgage-Backed   Securities.   Investing  in
Mortgage-Backed  Securities  involves certain risks,  including the failure of a
counter-party  to meet its  commitments,  adverse  interest rate changes and the
effects of  prepayments  on mortgage cash flows.  In addition,  investing in the
lowest  tranche of CMOs and REMIC  certificates  involves risks similar to those
associated   with   investing   in  equity   securities.   Further,   the  yield
characteristics of  Mortgage-Backed  Securities differ from those of traditional
fixed-income  securities.  The major differences typically include more frequent
interest and principal payments (usually monthly), the adjustability of interest
rates,   and  the  possibility   that  prepayments  of  principal  may  be  made
substantially earlier than their final distribution dates.

Prepayment  rates are  influenced  by changes in  current  interest  rates and a
variety  of  economic,  geographic,  social  and  other  factors  and  cannot be
predicted with  certainty.  Both  adjustable  rate mortgage loans and fixed rate
mortgage  loans may be 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
rate and  prepayment  rate  scenarios,  the Fund may fail to  recoup  fully  its
investment in Mortgage-Backed  Securities notwithstanding any direct or indirect
governmental,  agency  or  other  guarantee.  When the  Fund  reinvests  amounts
representing payments and unscheduled prepayments of principal, it may receive a

                                       4

<PAGE>

rate of  interest  that is  lower  than  the rate on  existing  adjustable  rate
mortgage  pass-through  securities.   Thus,   Mortgage-Backed   Securities,  and
adjustable  rate mortgage  pass-through  securities in  particular,  may be less
effective than other types of U.S. Government  securities as a means of "locking
in" interest rates.

Conversely,  in a rising interest rate environment,  a declining prepayment rate
will  extend  the  average  life  of  many  Mortgage-Backed   Securities.   This
possibility is often referred to as extension  risk.  Extending the average life
of a Mortgage-Backed  Security  increases the risk of depreciation due to future
increases in market interest rates.

Risk  Associated With Specific Types of Derivative  Debt  Securities.  Different
types of derivative  debt  securities are subject to different  combinations  of
prepayment,  extension  and/or interest rate risk.  Conventional  mortgage pass-
through  securities  and  sequential pay CMOs are subject to all of these risks,
but are typically  not  leveraged.  Thus,  the magnitude of exposure may be less
than for more leveraged Mortgage-Backed Securities.

Planned  amortization  class ("PAC") and target  amortization  class ("TAC") CMO
bonds 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." To the extent that  prepayment  rates
remain within these prepayment  ranges,  the residual or support tranches of PAC
and TAC CMOs  assume the extra  prepayment,  extension  and  interest  rate risk
associated with the underlying mortgage assets.

The risk of early  prepayments is the primary risk associated with interest only
debt  securities  ("IOs"),   super  floaters,   other  leveraged  floating  rate
instruments and Mortgage-Backed  Securities  purchased at a premium to their par
value.  In some  instances,  early  prepayments may result in a complete loss of
investment in certain of these  securities.  The primary risks  associated  with
certain other derivative debt securities are the potential  extension of average
life and/or depreciation due to rising interest rates.

These  securities  include  floating rate securities  based on the Cost of Funds
Index ("COFI floaters"), other "lagging rate" floating rate securities, floating
rate securities that are subject to a maximum interest rate ("capped floaters"),
Mortgage- Backed Securities purchased at a discount,  leveraged inverse floating
rate securities  ("inverse  floaters"),  principal only debt securities ("POs"),
certain residual or support tranches of CMOs and index amortizing  notes.  Index
amortizing  notes  are  not  Mortgage-Backed  Securities,  but  are  subject  to
extension  risk  resulting  from the issuer's  failure to exercise its option to
call or redeem the notes before their stated  maturity date.  Leveraged  inverse
IOs combine several elements of the Mortgage- Backed Securities  described above
and thus present an especially intense combination of prepayment,  extension and
interest rate risks.

Other types of floating rate  derivative  debt  securities  present more complex
types of interest  rate risks.  For example,  range  floaters are subject to the
risk that the  coupon  will be  reduced to below  market  rates if a  designated
interest rate floats outside of a specified  interest rate band or collar.  Dual
index or yield curve  floaters  are subject to  depreciation  in the event of an
unfavorable change in the spread between two designated interest rates.  X-reset
floaters  have a coupon that  remains  fixed for more than one  accrual  period.
Thus, the type of risk involved in these securities depends on the terms of each
individual X-reset floater.

Repurchase Agreements.  In a repurchase agreement the Fund buys a security for a
relatively short period (usually not more than 7 days) subject to the obligation
to  resell  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 or lack of
access to income  during  this period as well as the  expense of  enforcing  its
rights.

Reverse Repurchase  Agreements.  The Fund may also enter into reverse repurchase
agreements  which  involve the sale of U.S.  Government  securities  held in its
portfolio to a bank or securities  firm with an agreement that the Fund will buy
back the  securities  at a fixed  future  date at a fixed  price  plus an agreed
amount of interest  which may be  reflected  in the  repurchase  price.  Reverse
repurchase agreements are considered to be borrowings by the Fund. The Fund will
use proceeds obtained from the sale of securities pursuant to reverse repurchase
agreements  to purchase  other  investments.  The use of borrowed  funds to make
investments is a practice known as "leverage," which is considered  speculative.
Use of reverse repurchase agreements is an investment technique that is intended
to  increase  income.  Thus,  the Fund  will  enter  into a  reverse  repurchase
agreement only when the Adviser determines that the interest income to be earned
from the investment of the proceeds is greater than the interest  expense of the
transaction.  However,  there is a risk that interest expense will  nevertheless
exceed the income earned.  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 that 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  (plus any accrued  interest
thereon)  under  such  agreements.  In  addition,  the Fund will not enter  into
reverse  repurchase  agreements  or borrow  money,  except  that as a  temporary
measure for  extraordinary or emergency  purposes the Fund may borrow from banks
in aggregate  amounts at any one time  outstanding  not exceeding 33 1/3% of the
total assets  (including  the amount  borrowed) of the Fund valued at market and
the Fund may not purchase any securities at any time when  borrowings  exceed 5%
of  the  total  assets  of  the  Fund  (taken  at  market).  Forward  commitment
transactions shall not constitute borrowings and interest paid on any borrowings
will reduce the Fund's net investment  income.  The Fund will enter into reverse
repurchase  agreements  only with  selected  registered  broker/dealers  or with
federally  insured banks or savings and loan  associations  that are approved in
advance as being creditworthy by the Trustees.  Under procedures  established by
the  Trustees,  the  Adviser  will  monitor  the  creditworthiness  of the firms
involved.

Restricted Securities.  The Fund may purchase securities that are not registered
("restricted  securities")  under  the  Securities  Act of  1933  ("1933  Act"),
including  commercial  paper  issued in reliance on Section 4(2) of the 1933 Act
and securities offered and sold to "qualified  institutional  buyers" under Rule

                                       6

<PAGE>

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

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 that, by virtue of its exercise price or otherwise, reduces the
Fund's net  exposure on its written  option  position.  A written call option on
securities is typically  covered by maintaining  the securities that are subject
to the option in a  segregated  account.  The Fund may cover  call  options on a
securities  index by owning  securities  whose price  changes are expected to be
similar to those of the underlying index.

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

Purchasing   Options.   The  Fund  would  normally   purchase  call  options  in
anticipation  of an  increase,  or put  options  in  anticipation  of a decrease
("protective  puts") in the market value of  securities  of the type in which it

                                       7

<PAGE>

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  that 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 that 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

                                       8

<PAGE>

cease to exist.  However,  outstanding  options on that  exchange  that had been
issued  by the  Options  Clearing  Corporation  as a result  of  trades  on that
exchange would continue to be exercisable in accordance with their terms.

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

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

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

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

Positions taken in the futures markets are not normally held to maturity but are
instead liquidated  through offsetting  transactions that 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

                                       9

<PAGE>

based on other financial  instruments,  securities indices or other indices, the
Fund may also enter into such futures contracts as part of its hedging strategy.
Although under some  circumstances  prices of securities in the Fund's portfolio
may be more or less volatile than prices of such futures contracts,  the Adviser
will  attempt to  estimate  the 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 that 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 that 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

                                       10

<PAGE>

held by the Fund or securities or  instruments  that it expects to purchase.  As
evidence  of its hedging  intent,  the Fund  expects  that on 75% or more of the
occasions on which it takes a long  futures or option  position  (involving  the
purchase of futures contracts),  the Fund will have purchased, or will be in the
process of  purchasing,  equivalent  amounts of related  securities  in the cash
market at the time when the futures or option  position is closed out.  However,
in particular cases, when it is economically advantageous for the Fund to do so,
a long futures  position may be terminated  or an option may expire  without the
corresponding purchase of securities or other assets.

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.  The Fund will  engage in
transactions  in futures  contracts and related  options only to the extent such
transactions  are consistent with the  requirements of the Internal Revenue Code
of 1986,  as amended  (the  "Code"),  for  maintaining  its  qualification  as a
regulated investment company for federal income tax purposes.

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

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

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

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

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

                                       11

<PAGE>

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  and forward  commitment  basis also
involves a risk of loss if the value of the  security to be  purchased  declines
prior to the settlement date.

On the date the Fund  enters  into an  agreement  to  purchase  securities  on a
when-issued or forward  commitment  basis, the Fund will segregate in a separate
account cash or liquid securities on any type of 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  that  matures  on or  before  the  forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior  security and will be excluded from the  calculation
of the Fund's borrowings and other senior  securities.  For financial  reporting
and tax  purposes,  the  Fund  treats  mortgage  dollar  rolls  as two  separate
transactions;   one  involving  the  purchase  of  a  security  and  a  separate
transaction  involving a sale. The Fund does not currently  intend to enter into
mortgage dollar roll transactions that are accounted for as a financing.

Asset-Backed  Securities.  The  Fund may  invest  a  portion  of its  assets  in
asset-backed  securities  which are rated in the  highest  rating  category by a
nationally recognized  statistical rating organization (e.g., S&P or Moody's) or
if not so rated, of equivalent investment quality in the opinion of the Adviser.

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

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

                                       12

<PAGE>

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

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

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

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

                                       13

<PAGE>

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."

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 to 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 does not invest for the purpose of seeking  short-term
profits.  The Fund's  investment  securities  may be changed,  however,  without
regard to the  holding  period  of these  securities  (subject  to  certain  tax
restrictions),  when the Adviser  deems that this  action will help  achieve the
Fund's objective given a change in an issuer's  operations or changes in general
market  conditions.  Short-term  trading  may  have  the  effect  of  increasing
portfolio  turnover  rate. A high rate of portfolio  turnover  (100% or greater)
involves  corresponding  higher  transaction  expenses  and  may  make  it  more
difficult for the Fund to qualify as a regulated  investment company for federal
income tax purposes.  The Fund's  portfolio rate is set forth in the table under
the caption "Financial Highlights" in the Prospectus.
    

INVESTMENT RESTRICTIONS

   
Fundamental Investment Restrictions.  The following investment restrictions will
not be changed without approval of a majority of the Fund's  outstanding  voting
securities  which,  as  used  in the  Prospectus  and  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:
    


                                       14

<PAGE>

1.       borrow money,  except that as a temporary  measure for extraordinary or
         emergency  purposes the Fund may borrow from banks in aggregate amounts
         at any one time  outstanding  not exceeding 33 1/3% of the total assets
         (including the amount  borrowed) of the Fund valued at market;  and the
         Fund may not purchase any securities at any time when borrowings exceed
         5% of the total  assets  of the Fund  (taken  at  market  value).  This
         borrowing  restriction does not prohibit the use of reverse  repurchase
         agreements (see "Reverse Repurchase Agreements").  For purposes of this
         investment  restriction,  forward  commitment  transactions  shall  not
         constitute borrowings.  Interest paid on any borrowings will reduce the
         Fund's net investment income;

2.       make short  sales of  securities  or purchase  any  security on margin,
         except  that the Fund  may  obtain  such  short-term  credit  as may be
         necessary for the clearance of purchases and sales of securities  (this
         restriction  does not apply to  securities  purchased on a  when-issued
         basis);

3.       underwrite  securities  issued by other persons,  except insofar as the
         Fund may technically be deemed an underwriter  under the Securities Act
         of 1933 in selling a security,  and except that the Fund may invest all
         or  substantially  all of its assets in another  registered  investment
         company  having  substantially  the same  investment  objectives as the
         Fund;

4.       make  loans  to  other  persons  except  (a)  through  the  lending  of
         securities  held  by  the  Fund,  (b)  through  the  purchase  of  debt
         securities in accordance with the investment  policies of the Fund (the
         entry into repurchase  agreements is not considered a loan for purposes
         of this restriction);

5.       with respect to 75% of its total assets, purchase the securities of any
         one  issuer  (except  securities  issued  or  guaranteed  by  the  U.S.
         Government and its agencies or instrumentalities, as to which there are
         no percentage  limits or  restrictions)  if immediately  after and as a
         result of such  purchase  (a) more  than 5% of the value of its  assets
         would be invested in that issuer,  or (b) the Fund would hold more than
         10% of the outstanding  voting  securities of that issuer,  except that
         the Fund may invest all or  substantially  all of its assets in another
         registered  investment company having substantially the same investment
         objectives as the Fund;

6.       purchase or sell real estate (including limited partnership  interests)
         other than  securities  secured  by real  estate or  interests  therein
         including  mortgage-related  securities  or  interests  in oil,  gas or
         mineral  leases in the ordinary  course of business  (the Fund reserves
         the  freedom of action to hold and to sell real  estate  acquired  as a
         result of the ownership of securities);

7.       invest more than 25% of its total assets in the  securities  of issuers
         whose principal business activities are in the same industry (excluding
         obligations of the U.S. Government,  its agencies and instrumentalities
         and  repurchase  agreements)  except  that the Fund may  invest  all or
         substantially  all of  its  assets  in  another  registered  investment
         company having substantially the same objectives as the Fund;

   
8.       issue any senior  security  (as that term is defined in the  Investment
         Company Act of 1940 (the "Investment Company Act")) if such issuance is
         specifically  prohibited by the Investment Company Act or the rules and
         regulations promulgated thereunder; or
    

                                       15

<PAGE>

9.       invest in  securities of any company if, to the knowledge of the Trust,
         any officer or director of the Trust or its Adviser  owns more than 1/2
         of 1% of the  outstanding  securities  of such  company,  and all  such
         officers  and  directors  own  in the  aggregate  more  than  5% of the
         outstanding securities of such company.

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

The Fund may not:

(a)      invest  in  companies  for  the  purpose  of   exercising   control  or
         management, except that the Fund may invest all or substantially all of
         its   assets  in   another   registered   investment   company   having
         substantially the same investment restrictions as the Fund;

   
(b)      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.

(c)      invest in  commodities,  except  that the Fund may  purchase  and sell:
         options on securities  and  securities  indices,  futures  contracts on
         securities and securities indices and options on these futures, forward
         commitments,  when-issued  securities,  securities  index  put or  call
         warrants and repurchase  agreements entered into in accordance with the
         Fund's investment policies;

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

If a percentage  restriction on investment or utilization of assets as set forth
above  is  adhered  to at the time an  investment  is made,  a later  change  in
percentage  resulting from changes in the value of the Fund's assets will not be
considered a violation of the restriction.
    

THOSE RESPONSIBLE FOR MANAGEMENT

   
The business of the Fund is managed by the  Trustees who elect  officers who are
responsible for the day-to-day  operations of the Fund and who execute  policies
formulated  by the  Trustees.  Several of the officers and Trustees of the Trust
are also Officers and Directors of the Adviser or Officers and Directors of John
Hancock Funds, Inc.
("John Hancock Funds").

From  December 22, 1994 until  December 22, 1996,  the Trustees  established  an
Advisory  Board to  facilitate a smooth  transition  between  Transamerica  Fund
Management Company ("TFMC"),  the prior investment adviser, and the Adviser. The
members of the Advisory Board were distinct from the Trustees, did not serve the
Fund in any other  capacity and were persons who had no power to determine  what
securities were purchased or sold and behalf of the Fund.

Compensation  of the Trustees and Advisory Board.  The following  tables provide
information regarding the compensation paid by the Fund and the other investment
companies in the John Hancock Fund Complex to the  Independent  Trustees and the
Advisory Board members for their services.  Messrs. Boudreau,  Scipione, and Ms.
Hodsdon, each a non-Independent  Trustees,  and each of the officers of the Fund
who are interested persons of the Adviser, are compensated by the Adviser and/or
its affiliates and receive no compensation from the Fund for their services.

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.  As
manager and investment  adviser,  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 or 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

                                       26

<PAGE>

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,  equal on an annual basis to
0.40%, of the average daily net assets of the Fund.
    

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

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

Pursuant to the Advisory  Agreement,  the Adviser is not liable 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  applicable  Advisory
Agreement or any extension,  renewal or amendment  thereof remains in effect. If
the Fund's  Advisory  Agreement is no longer in effect,  the Fund (to the extent
that it lawfully  can) will cease to use such name or any other name  indicating
that it is advised by or otherwise connected with the Adviser. In addition,  the
Adviser or the Life  Company may grant the  non-exclusive  right to use the name
"John Hancock" or any similar name to any other corporation or entity, including
but not  limited  to any  investment  company  of which the Life  Company or any
subsidiary  or  affiliate  thereof  or  any  successor  to the  business  of any
subsidiary or affiliate thereof shall be the investment adviser.

Under the Fund's master/feeder  structure (which was terminated on September 22,
1995 pursuant to an Agreement and Plan of Liquidation and Termination dated June
13, 1995)  existing  for the fiscal  years ended March 31,  1994,  1995 and 1996
(until  September 22,  1995),  the Fund invested all of its assets in Adjustable
U.S.  Government  Fund (the  "Portfolio").  During  these years,  advisory  fees
payable by the Portfolio to TFMC, the Portfolio's former investment adviser, and
borne   indirectly  by  the  Fund,   amounted  to  $184,072,   $86,085  and  $0,
respectively.  For the fiscal years ended March 31, 1996 and 1997, advisory fees
paid by the Portfolio to the Adviser and borne indirectly by the Fund,  amounted
to $137,927 and $132,601, respectively. For the years ended March 31, 1995, 1996

                                       27

<PAGE>

and 1997 TFMC (until December 22, 1994), the Adviser received fees of $0, $0 and
$10,548, respectively.

The initial term of the Advisory  Agreement  expires on September 25, 1997.  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 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.
    

Administration  Agreement.   Pursuant  to  an  administration  agreement,  dated
December 22, 1994, the Adviser provided the Fund with general office  facilities
and supervised the overall  administration  of the Fund  including,  among other
responsibilities, the negotiation of contracts and fees with, and the monitoring
of performance  and billings of the  independent  contractors  and agents of the
Fund, the preparation and filing of all documents required for compliance by the
Fund with  applicable  laws and regulations and arranging for the maintenance of
books and records  (other than  accounting  books and records) of the Fund.  The
Adviser paid all  compensation  of the  Trustees,  officers and employees of the
Fund who were affiliated persons of the Adviser.  The  administration  agreement
terminated in September 1995.

Under the  administration  agreement,  the Adviser  would have received from the
Fund, a fee at an annual rate of 0.10% of the Fund's  average  daily net assets,
subject to the expense  limitation  provisions  described  below. For the fiscal
years ended March 31, 1994 and 1995,  respectively,  administration fees paid by
the Fund to TFMC, the Fund's former administrator would have amounted to $46,091
and $21,511,  respectively;  and the Adviser would have received  $7,171 for the
year ended March 31, 1995;  however,  all such fees were not imposed pursuant to
the fee and expense limitation arrangements then in effect.

Under the  administration  agreement,  neither the Adviser nor its personnel was
liable for any error of judgment or mistake of law or for any act or omission in
the  administration  of the Fund  except for willful  misfeasance,  bad faith or
gross negligence in the performance of its duties or from reckless  disregard of
its obligations and duties under the administration agreement.

Administrative Services Agreement.  During the fiscal years ended March 31, 1994
and 1995, the Fund was a party to an administrative services agreement with TFMC
(the "Services  Agreement"),  pursuant to which TFMC performed  bookkeeping  and
accounting  services and functions,  including preparing and maintaining various
accounting  books,  records and other documents and keeping such general ledgers
and  portfolio  accounts as are  reasonably  necessary  for the operation of the
Fund.  Other  administrative  services  included  communications  in response to
shareholder  inquiries  and  certain  printing  expenses  of  various  financial
reports. In addition,  such staff and office space, facilities and equipment was
provided as  necessary  to provide the  required  administrative  services.  The
Services Agreement was amended in connection with the appointment of the Adviser
as  administrator  to the Fund to  permit  services  under the  Agreement  to be
provided  by  the  Adviser  and  its  affiliates.  The  Services  Agreement  was
terminated during the fiscal year ended March 31, 1995.

For the  fiscal  years  ended  March 31,  1994 and  1995,  the Fund paid to TFMC
(pursuant to the Services Agreement), $18,021 and $9,604, respectively, of which

                                       28

<PAGE>

$14,730  and  $8,164,  respectively,  was paid to TFMC and  $3,291  and  $1,440,
respectively,  was paid for certain  data  processing  and  pricing  information
services.

For the fiscal  years  ended March 31, 1994 and 1995,  the  Portfolio  paid TFMC
(pursuant to the Services  Agreement),  $38,012 and  $24,461,  respectively,  of
which  $26,722  and  $17,704,  respectively,  was paid to TFMC and  $11,290  and
$6,757,  respectively,  were  paid  for  certain  data  processing  and  pricing
information services.

   
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  March 31,  1997,  the Fund paid the
Adviser $4,508 for services under this agreement from the effective date of July
1, 1996.

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

DISTRIBUTION CONTRACTS

   
The Fund has a  Distribution  Agreement  with  John  Hancock  Funds.  Under  the
agreement,  John  Hancock  Funds is  obligated  to use its best  efforts to sell
shares  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 that 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 March 31,  1994,  1995 and 1996 were  $59,793,  $24,555 and
$4,976, respectively. Of such amounts, $7,455, $4,090 and $0, respectively, were
retained by the Fund's former distributor,  Transamerica Fund Distributors, Inc.
or the  current  distributor  in 1995 and  1996,  as the  case  may be,  and the
remainder was reallowed to dealers.

   
The  Fund's   Trustees,   including  the  Independent   Trustees,   adopted  new
Distribution  Plans with  respect to Class A and Class B shares  (the  "Plans"),
pursuant  to Rule  12b-1  under the  Investment  Company  Act.  Such  Plans were
approved by a majority of the  outstanding  shares of each  respective  class on
December 16, 1994 and became effective on December 22, 1994. Under the Plans the
Fund will pay distribution and service fees at an aggregate annual rate of up to
0.25%  and  1.00%,  respectively,   of  the  Fund's  average  daily  net  assets
attributable to shares of that class.  However,  the service fee will not exceed
0.25% of the  Fund's  average  daily net  assets  attributable  to each class of
shares.  The distribution  fees will be used to reimburse the John Hancock Funds
for their distribution  expenses,  including but not limited to: (i) initial and

                                       29

<PAGE>

ongoing sales  compensation to Selling Brokers and others (including  affiliates
of the John Hancock Funds) engaged in the sale of Fund shares;  (ii)  marketing,
promotional and overhead  expenses  incurred in connection with the distribution
of Fund shares; and (iii) with respect to Class B shares only, interest expenses
on  unreimbursed  distribution  expenses.  The  service  fees  will  be  used to
compensate  Selling  Brokers  and  others for  providing  personal  and  account
maintenance services to shareholders. In the event the John Hancock Funds is not
fully  reimbursed  for  payments or expenses  they incur under the Class A Plan,
these  expenses will not be carried beyond twelve months from the date they were
incurred.  Unreimbursed  expenses under the Class B Plan will be carried forward
together with interest on the balance of these unreimbursed  expenses.  The Fund
does not treat  unreimbursed  expenses  under the Class B Plan as a liability of
the Fund,  because the Trustees may terminate the Class B Plan at any time.  For
the fiscal year ended March 31, 1997,  an aggregate of $398,870 of  distribution
expenses  or 5.39% of the  average net assets of the Class B shares of the Fund,
was not reimbursed or recovered by the John Hancock Funds through the receipt of
deferred sales charges or 12b-1 fees in prior periods.

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

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

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.

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 the 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 for each fund and class is determined  each business day at the close of
regular  trading on the New York Stock  Exchange  (typically  4:00 p.m.  Eastern
Time) by dividing a class's net assets by the number of its shares  outstanding.
On any day an international  market is closed and the New York Stock Exchange is
open,  any foreign  securities  will be valued at the prior day's close with the
current day's  exchange  rate.  Trading of foreign  securities may take place on
Saturdays and U.S.  business holidays on which the Fund's NAV is not calculated.
Consequently,  the  Fund's  portfolio  securities  may  trade and the NAV of the
Fund's  redeemable  securities  may be  significantly  affected  on days  when a
shareholder has no access to the Fund.

INITIAL SALES CHARGE ON CLASS A SHARES

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

The sales  charges  applicable  to  purchases  of Class A shares of the Fund are
described in the Prospectus. Methods of obtaining 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 Charge.  Class A shares may be offered  without a front-end  sales
charge or CDSC to various individuals and institutions as follows:

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

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

o        A Trustee or officer of the Trust; a Director or officer of the Adviser
         and  its   affiliates   or   Selling   Brokers;   employees   or  sales
         representatives of any of the foregoing; retired officers, employees or
         Directors of any of the  foregoing;  a member of the  immediate  family
         (spouse,  children,  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.*


                                       32

<PAGE>

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

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

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

                     Amount Invested                                CDSC Rate
                     ---------------                                ---------

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

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

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

Combination  Privilege.  In calculating the sales charge applicable to purchases
of Class A shares  made at one time,  the  purchases  will be combined to reduce
sales charges if made by (a) an individual, his or her spouse and their children
under the age of 21, purchasing  securities for his or their own account,  (b) a
trustee or other  fiduciary  purchasing for a single trust,  estate or fiduciary
account and (c) groups  which  qualify  for the Group  Investment  Program  (see
below).   Further  information  about  combined  purchases,   including  certain
restrictions on combined group purchases,  is available from Signature  Services
or a Selling Broker's representative.
    
Accumulation Privilege.  Investors (including investors combining purchases) who
are  already  Class A  shareholders  may also  obtain the benefit of the reduced
sales charge by taking into account not only the amount then being  invested but
also the  purchase  price or current  value of the Class A shares  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.
    

                                       33

<PAGE>

   
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  $50,000 or more invested  during the specified  period from the
date of the LOI or from a date  within  ninety  (90) days  prior  thereto,  upon
written  request to  Signature  Services.  The sales  charge  applicable  to all
amounts  invested under the LOI is computed as if the aggregate  amount intended
to be invested had been invested  immediately.  If such aggregate  amount is not
actually  invested,  the  difference  in the sales charge  actually paid and the
sales  charge  payable had the LOI not been in effect is due from the  investor.
However,  for the purchases actually made within the specified period (either 13
or 48 months),  the sales charge  applicable  will not be higher than that which
would have been applied  (including  accumulations and combinations) had the LOI
been for the amount actually invested.
    

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

   
Contingent Deferred Sales Charge.  Class B shares which are redeemed within four
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

                                       34

<PAGE>

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
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 a CDSC,
unless indicated otherwise, in the circumstances defined below:
    

For all account types:

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

                                       35

<PAGE>

*        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 that 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

         401(a)  of the Code  (such as  401(k),  Money  Purchase  Pension  Plan,
         Profit-Sharing Plan).

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

</TABLE>
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

                                       37

<PAGE>

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
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
events.  Therefore, a shareholder should not purchase Class A and Class B shares

                                       38

<PAGE>

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 due date of any investment.

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

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

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

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

Retirement plans participating in Merrill Lynch's servicing programs:

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

                                       39

<PAGE>

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

DESCRIPTION OF THE FUND'S SHARES

   
The Trustees of the Trust are  responsible for the management and supervision of
the Fund.  The  Declaration  of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of the Fund, without
par value.  Under the  Declaration of Trust,  the Trustees have the authority to
create and classify shares of beneficial  interest in separate  series,  without
further action by  shareholders.  As of the date of this Statement of Additional
Information,  the Trust has two Funds and only one series and the Trustees  have
not authorized any additional series of 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 or series 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 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.

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

                                       40

<PAGE>

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
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 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 Code and intends to continue to so qualify
for each taxable year. As such and by complying with the  applicable  provisions
of  the  Code   regarding  the  sources  of  its  income,   the  timing  of  its
distributions,  and the  diversification  of its  assets,  the Fund  will not be
subject to Federal  income tax on its taxable  income  (including  net  realized
capital  gains) which is  distributed  to  shareholders  in accordance  with the
timing requirements of the Code.
    

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

Distributions  from the  Fund's  current or  accumulated  earnings  and  profits
("E&P") will be taxable  under the Code for investors who are subject to tax. If
these  distributions  are  paid  from the  Fund's  "investment  company  taxable
income," they will be taxable as ordinary income;  and if they are paid from the
Fund's "net capital gain," they will be taxable as long-term  capital gain. (Net
capital  gain is the  excess  (if any) of net  long-term  capital  gain over net
short-term  capital loss, and investment  company  taxable income is all taxable
income and  capital  gains,  other than net capital  gain,  after  reduction  by
deductible  expenses.) Some distributions from investment company taxable income
and/or  net  capital  gain  may  be  paid  in  January  but  may be  taxable  to
shareholders  as if they had been received on December 31 of the previous  year.
The  tax  treatment  described  above  will  apply  without  regard  to  whether
distributions  are received in cash or reinvested  in  additional  shares of the
Fund.

Distributions,  if any,  in excess of E&P will  constitute  a return of  capital
under the Code, which will first reduce an investor's  federal tax basis in Fund
shares and then, to the extent such basis is exceeded,  will generally give rise
to capital gains.  Shareholders who have chosen automatic  reinvestment of their
distributions  will have a federal tax basis in each share received  pursuant to
such a  reinvestment  equal to the amount of cash they would have  received  had
they  elected  to receive  the  distribution  in cash,  divided by the number of
shares received in the reinvestment.


                                       41

<PAGE>

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

Upon a redemption  of shares of the Fund  (including by exercise of the exchange
privilege) a shareholder  may realize a taxable gain or loss  depending upon the
amount of the proceeds and the investor's basis in his shares. Such gain or loss
will be treated as capital gain or loss if the shares are capital  assets in the
shareholder's  hands and will be long-term  or  short-term,  depending  upon the
shareholder's tax holding period for the shares and subject to the special rules
described  below.  A sales charge paid in purchasing  Class A shares of the Fund
cannot be taken into  account for  purposes of  determining  gain or loss on the
redemption or exchange of such shares within 90 days after their purchase to the
extent shares of the Fund or another John Hancock Fund are subsequently acquired
without  payment of a sales  charge  pursuant  to the  reinvestment  or exchange
privilege.   This  disregarded   charge  will  result  in  an  increase  in  the
shareholder's  tax basis in the shares  subsequently  acquired.  Also,  any loss
realized on a redemption  or exchange may be disallowed to the extent the shares
disposed  of are  replaced  with other  shares of the Fund within a period of 61
days  beginning  30 days before and ending 30 days after the shares are disposed
of, such as pursuant to automatic  dividend  reinvestments.  In such a case, the
basis of the shares  acquired will be adjusted to reflect the  disallowed  loss.
Any loss realized upon the redemption of shares with a tax holding period of six
months or less will be treated as a long-term  capital loss to the extent of any
amounts treated as distributions of long-term  capital gain with respect to such
shares.

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

   
For Federal  income tax  purposes,  the Fund is permitted to carry forward a net
capital loss in any year to offset its own net capital gains, if any, during the
eight years following the year of the loss. To the extent subsequent net capital
gains are offset by such  losses,  they  would not result in Federal  income tax
liability to the Fund and, as noted above,  would not be  distributed as such to

                                       42

<PAGE>

shareholders.  The Fund has $13,214,712 of capital loss  carryforwards as of the
tax year ended December 31, 1996, of which $5,412,804 expires in 1997,  $653,763
expires in 1998, $2,207,560 expires in 1999, $23,234 expires in 2000, $4,062,681
expires  in  2001,  $427,159  expires  in 2002  and  $427,511  expires  in 2004,
available to offset future net capital gains.
    

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

The Fund is required to accrue income on any debt securities that have more than
a de minimis amount of original issue discount (or debt securities acquired at a
market  discount,  if the Fund  elects  to  include  market  discount  in income
currently) prior to the receipt of the corresponding cash payments.  The mark to
market  rules  applicable  to certain  options and futures  contracts,  may also
require  the Fund to  recognize  gain  without  a  concurrent  receipt  of cash.
However,  the  Fund  must  distribute  to  shareholders  for each  taxable  year
substantially all of its net income and net capital gains, including such income
or gain, to qualify as a regulated  investment  company and avoid  liability for
any federal income or excise tax. Therefore, the Fund may have to dispose of its
portfolio  securities under  disadvantageous  circumstances to generate cash, or
may have to leverage itself by borrowing the cash, to satisfy these distribution
requirements.

A state  income (and  possibly  local income  and/or  intangible  property)  tax
exemption is generally available to the extent (if any) the Fund's distributions
are derived from interest on (or, in the case of intangibles 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,
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 in a
manner  that,  under  certain  circumstances,   may  limit  the  extent  of  its
participation in such transactions.




                                       43

<PAGE>

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

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,  certain of the Fund's  losses on its  transactions  involving  options or
futures  contracts  and/or  offsetting or successor  portfolio  positions may be
deferred  rather than being taken into  account  currently  in  calculating  the
Fund's taxable income or gain.  Certain of these transactions may also cause the
Fund to dispose  of  investments  sooner  than would  otherwise  have  occurred.
Certain 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.
These transactions may therefore affect the amount,  timing and character of the
Fund's  distributions  to  shareholders.  The Fund will take  into  account  the
special tax rules (including consideration of available elections) applicable to
options and futures contracts in order to seek to minimize any potential adverse
tax consequences.

The  foregoing  discussion  relates  solely to U.S.  Federal  income  tax law as
applicable to U.S. persons (i.e.,  U.S.  citizens or residents and U.S. domestic
corporations,  partnerships,  trusts or estates)  subject to tax under such law.
The discussion does not address special tax rules  applicable to certain classes
of investors,  such as tax-exempt entities,  insurance companies,  and financial
institutions.  Dividends, capital gain distributions,  and ownership of or gains
realized on the  redemption  (including  an exchange) of Fund shares may also be
subject to state and local  taxes.  Shareholders  should  consult  their own tax
advisers as to the  Federal,  state or local tax  consequences  of  ownership of
shares  of, and  receipt of  distributions  from,  the Fund in their  particular
circumstances.

Non-U.S.  investors  not engaged in a U.S.  trade or  business  with which their
investment in the Fund is effectively  connected will be subject to U.S. Federal
income  tax  treatment  that is  different  from  that  described  above.  These
investors may be subject to nonresident alien withholding tax at the rate of 30%
(or a lower rate under an applicable tax treaty) on amounts  treated as ordinary
dividends  from a Fund  and,  unless  an  effective  IRS Form W-8 or  authorized
substitute  for Form W-8 is on file, to 31% backup  withholding on certain other
payments from the Fund.  Non-U.S.  investors  should  consult their tax advisers
regarding such  treatment and the  application of foreign taxes to an investment
in the Fund.

The Fund is not subject to  Massachusetts  corporate  excise or franchise taxes.
Provided  that the Fund  qualifies as a regulated  investment  company under the
Code, it will also not be required to pay any Massachusetts income tax.

CALCULATION OF PERFORMANCE

   
For the 30-day period ended March 31, 1997, the annualized  yield for the Fund's
Class A shares and Class B shares  were 6.13% and 5.56%,  respectively.  Average

                                       44

<PAGE>

annual  return  for the Fund's  Class A and Class B shares  for the period  from
December 31, 1991  (inception  of the Fund) through March 31, 1997 was 4.10% and
4.02%, respectively. For the one year period ended March 31, 1997 annual returns
were 1.42% and 0.84%,  respectively,  for Class A and B shares of the Fund.  For
the five year period ended March 31, 1997, the average annual returns were 3.90%
and 3.86%, respectively.
    

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

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

Where:

a =       dividends and interest earned during the period.

b =       net expenses accrued during the period.

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

d =       the maximum offering price per share on the last day of the period 
          (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

n =       number of years

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

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

                                       45

<PAGE>

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 and bank deposit
vehicles such as Lipper Analytical Services, Inc.'s "Lipper -- Fixed Income Fund
Performance  Analysis," a monthly  publication  which  tracks net assets,  total
return,  and yield on fixed income mutual funds in the United  States.  Ibbotson
and Associates,  CDA  Weisenberger  and F.C. Towers are also used for comparison
purposes, as well a the Russell and Wilshire Indices.
    

Performance  rankings and ratings  reported  periodically in national  financial
publications  such as MONEY  Magazine,  FORBES,  BUSINESS  WEEK, THE WALL STREET
JOURNAL,  MICROPAL,  INC.,  MORNINGSTAR,  STANGER'S  and  BARRON'S,  may also be
utilized.  The Fund's promotional and sales literature may make reference to the
Fund's  "beta." Beta is a reflection of the  market-related  risk of the Fund by
showing how responsive the Fund is to the market.

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

BROKERAGE ALLOCATION

   
Decisions  concerning  the  purchase and sale of  portfolio  securities  and the
allocation  of  brokerage  commissions  are  made  by the  Adviser  pursuant  to
recommendations made by an investment  committee of the Adviser,  which consists
of officers  and  directors of the Adviser and  affiliates  and Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner  which,  in the opinion of the  Adviser,  will offer the best
price and market for the  execution  of each such  transaction.  Purchases  from
underwriters  of portfolio  securities  may include a commission or  commissions
paid by the issuer and  transactions  with dealers  serving as market  makers to
reflect a "spread." Debt securities are generally  traded on a net basis through
dealers  acting  for their own  account as  principals  and not as  brokers;  no
brokerage commissions are payable on these transactions.

In the U.S. and in some other countries,  debt securities are traded principally
in the  over-the-counter  market on a net basis through dealers acting for their
own  account  and not as  brokers.  In other  countries,  both  debt and  equity
securities  are traded on exchanges at fixed  commission  rates.  Commissions on

                                       46

<PAGE>

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 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 not make any 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  years  ended  March 31,  1997,  1996,  and 1995,  no
negotiated brokerage commissions were paid on portfolio transactions.

As permitted by Section 28(e) of the  Securities  Exchange Act of 1934, the Fund
may pay to a broker which provides  brokerage and research  services to the Fund
an amount of disclosed  commission  in excess of the  commission  which  another
broker would have  charged for  effecting  that  transaction.  This  practice is
subject  to a good  faith  determination  by the  Trustees  that  such  price is
reasonable  in  light  of the  services  provided  and to such  policies  as the
Trustees  may adopt from time to time.  During the fiscal  year ended  March 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
years  ended  March  31,  1997,  1996 and  1995,  the Fund did not  execute  any
portfolio transactions with any Affiliated Broker.

Distributors may act as broker for the Fund on exchange  transactions,  subject,
however,  to the general  policy of the Fund set forth above and the  procedures
adopted by the Trustees pursuant to the Investment Company Act. Commissions paid
to an  Affiliated  Broker  must be at least as  favorable  as  those  which  the
Trustees believe to be contemporaneously  charged by other brokers in connection

                                       47

<PAGE>

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.

                                   APPENDIX A

The ratings of Moody's Investors Service, Inc. and Standard & Poor's Corporation
represent  their opinions as to the quality of various debt  instruments.  Their
ratings are a generally  accepted  barometer of credit risk. They are,  however,
subject to certain limitations from an investor's  standpoint.  Such limitations
include  the  following:  the  rating of an issue is  heavily  weighted  by past
developments and does not necessarily reflect probable future conditions;  there
is  frequently  a lag between  the time a rating is assigned  and the time it is
updated;  and  there  are  varying  degrees  of  difference  in  credit  risk of
securities in each rating  category.  Therefore,  it should be understood,  that
ratings are not absolute  standards of quality.  Consequently,  debt instruments
with the same maturity,  coupon and rating may have different  yields while debt
instruments of the same maturity and coupon with different  ratings may have the
same yield.

Description of Bond Ratings Moody's Investors Service, Inc.

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

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

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

Baa: 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.

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

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


                                      A-1

<PAGE>

Caa:  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 principle or
interest.

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

C:  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 Ratings Group

AAA:  Bonds  rated AAA have the higher  rating  assigned  by  Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

AA:  Bonds  rated AA have a very  strong  capacity  to pay  interest  and  repay
principal and differ from the higher rated issues only in small degree.

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

BBB: Bonds rated BBB are regarded as having an adequate capacity to pay interest
and  repay  principal.   Whereas  they  normally  exhibit  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
bonds in this category than in higher rated categories.

BB, B,  CCC,  CC:  Debt  rated BB, B, CCC and CC 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 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.

C: The rating C is reserved for income bonds on which no interest is being paid.

Item 27. Indemnification

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

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

     Section 9(a) of the By-Laws of John Hancock Mutual Life  Insurance  Company
("the Insurance Company") provides,  in effect, that the Insurance Company will,
subject to  limitations  of law,  indemnify  each  present and former  director,
officer and employee of the of the Insurance  Company who serves as a Trustee or
officer of the  Registrant at the direction or request of the Insurance  Company
against  litigation  expenses  and  liabilities  incurred  while acting as such,
except  that  such  indemnification  does not  cover any  expense  or  liability
incurred or imposed in connection  with any matter as to which such person shall
be finally  adjudicated not to have acted in good faith in the reasonable belief
that his action was in the best interests of the Insurance Company. In addition,
no such person will be  indemnified  by the Insurance  Company in respect of any
liability or expense  incurred in  connection  with any matter  settled  without
final  adjudication  unless such  settlement  shall have been approved as in the
best interests of the Insurance Company either by vote of the Board of Directors
at a meeting  composed of directors  who have no interest in the outcome of such
vote, or by vote of the  policyholders.  The Insurance  Company may pay expenses
incurred in  defending  an action or claim in advance of its final  disposition,
but only upon receipt of an undertaking by the person  indemnified to repay such
payment if he should be determined not to be entitled to indemnification.

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

"Section  9.01.  Indemnity:  Any person made or threatened to be made a party to
any action,  suit or proceeding,  whether  civil,  criminal,  administrative  or
investigative,  by reason  of the fact  that he is or was at any time  since the
inception  of the  Corporation  a  director,  officer,  employee or agent of the
Corporation  or is or was at any time  since the  inception  of the  Corporation
serving at the request of the  Corporation as a director,  officer,  employee or
agent  of  another  corporation,  partnership,  joint  venture,  trust  or other
enterprise,  shall be indemnified by the Corporation against expenses (including
attorney's fees),  judgments,  fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding if
he acted in good faith and the  liability  was not  incurred  by reason of gross
negligence  or reckless  disregard of the duties  involved in the conduct of his
office, and expenses in connection therewith may be advanced by the Corporation,
all to the full extent authorized by the law."

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

                                      C-3

<PAGE>

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

Item 28. Business and Other Connections of Investment Advisers

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

Item 29. Principal Underwriters

     (a) John Hancock Funds acts as principal underwriter for the Registrant and
also serves as principal  underwriter  or distributor of shares for John Hancock
Cash Reserve, Inc., John Hancock Bond Trust, John Hancock Current Interest, John
Hancock Series Trust, John Hancock Tax-Free Bond Trust, John Hancock  California
Tax-Free Income Fund,  John Hancock  Capital  Series,  John Hancock Limited-Term

to time.

2.02  JHSS agrees that it will perform the following services:

<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

          (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

          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.

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.
