Overview
- --------------------------------------------------------------------------------

GOAL OF THE INTERNATIONAL/GLOBAL FUNDS

John Hancock international/global funds invest in foreign and U.S. securities.
Most of the funds invest primarily in stocks and seek long-term growth of
capital. Two funds invest primarily in bonds and seek current income or maximum
total return. Each fund has its own strategy and 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 to diversify a portfolio of domestic investments

o  are seeking access to markets that can be less accessible to individual
   investors

o  are seeking funds for the growth or income portion of an asset allocation
   portfolio

o  are investing for goals that are many years in the future

International/global funds may NOT be appropriate if you:

o  are investing with a shorter time horizon in mind

o  are uncomfortable with an investment whose value may vary substantially

o  want to limit your exposure to foreign securities

THE MANAGEMENT FIRM

   
All John Hancock international/global funds are managed by John Hancock
Advisers, Inc. Founded in 1968, John Hancock Advisers is a wholly owned
subsidiary of John Hancock Mutual Life Insurance Company and manages more than
$26 billion in assets.

REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST III
                                TICKER SYMBOL    CLASS A: JHGAX   CLASS B: FGLOX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip art] The fund seeks long-term growth of capital. To pursue this goal, the
fund invests primarily in common stocks of foreign and U.S. companies. The fund
maintains a diversified portfolio of company and government securities from
around the world. Under normal circumstances, the fund expects to invest in the
securities markets of at least three countries at any one time, potentially
including the U.S.

The fund does not maintain a fixed allocation of assets, either with respect to
securities type or to geography.

PORTFOLIO SECURITIES

[Clip art] Under normal circumstances, the fund invests at least 65% of assets
in common stocks and convertible securities, but may invest in virtually any
type of security, foreign or domestic, including preferred and convertible
securities, warrants and investment-grade debt securities. Not counting
short-term securities, the fund generally expects that no more than 5% of assets
will be invested in debt 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 up to 100% in these securities as a defensive tactic. The fund also may
invest in certain higher-risk securities, and may engage in other investment
practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements.

Because it invests internationally, the fund carries additional risks, including
currency, information, natural event and political risks. These risks, which may
make the fund more volatile than a comparable domestic growth fund, are defined
in "More about risk" starting on page 29. The risks of international investing
are higher in emerging markets such as those of Latin America, Southeast Asia
and Eastern Europe.

To the extent that the fund utilizes higher-risk securities and practices, it
takes on further risks that could adversely affect its performance. Please read
"More about risk" carefully before investing.

MANAGEMENT/SUBADVISER

[Clip art] Miren Etcheverry, John L.F. Wills, and Gerardo J. Espinoza lead the
portfolio management team. Ms. Etcheverry and Mr. Espinoza are senior vice
presidents and joined John Hancock Funds in December 1996, having been in the
investment business since 1978 and 1979, respectively. Mr. Wills is a senior
vice president of the adviser and managing director of the subadviser, John
Hancock Advisers International. He joined John Hancock Funds in 1987 and has
been in the investment business since 1969.

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) Includes a subadviser fee equal to 0.70% of the fund's net assets.
(4) Because of the 12b-1 fee, long-term shareholders may indirectly pay more

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

GOAL AND STRATEGY

[Clip art] The fund seeks long-term growth of capital. To pursue this goal, the
fund invests primarily in stocks of foreign and U.S. health care companies. The
fund defines health care companies as those deriving at least half of their
gross revenues, or committing at least half of their gross assets, to health
care-related activities. Under normal circumstances, the fund invests at least
65% of assets in these companies, including small- and medium-sized companies.
The fund expects to invest in the securities markets of at least three countries
at any one time, potentially including the U.S. Because the fund is
non-diversified, it may invest more than 5% of assets in securities of a single
issuer.

The fund has an independent advisory board composed of scientific and medical
experts to provide advice and consultation on health care developments.

PORTFOLIO SECURITIES

[Clip art] The fund invests primarily in foreign and domestic common stocks, and
may invest in warrants, preferred stocks and convertible debt 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 up to 100% in these securities as a defensive tactic. The fund also may
invest in certain higher-risk securities, and may engage in other investment
practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. Because the fund concentrates on a single
sector (health care), and because this sector has historically been volatile,
investors should expect above-average volatility.

Also, because the fund invests internationally, it carries additional risks,
including currency, information, natural event and political risks. These risks,
which may make the fund more volatile than a comparable domestic growth fund,
are defined in "More about risk" starting on page 29.

To the extent that the fund invests in smaller capitalization companies or
utilizes higher-risk securities and practices, it takes on further risks that
could adversely affect its performance. Please read "More about risk" carefully
before investing.

PORTFOLIO MANAGEMENT

[Clip art] Linda I. Miller, CFA, leader of the fund's portfolio management team
since January 1996, is a vice president of the adviser. She joined John Hancock
Funds in November 1995 and has been in the investment business with a focus on
the health care industry since 1980.

INVESTOR EXPENSES

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

 Annual fund operating expenses (as a % of average net assets)
- --------------------------------------------------------------------------------
 Management fee                          0.80%     0.80%
 12b-1 fee(3)                            0.30%     1.00%
 Other expenses                          0.58%     0.58%
 Total fund operating expenses           1.68%     2.38%
    

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                  $66     $100      $137     $239
 Class B shares
   Assuming redemption
   at end of period              $74     $104      $147     $254
   Assuming no redemption        $24      $74      $127     $254
    

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.

Global Technology Fund
REGISTRANT NAME: JOHN HANCOCK SERIES TRUST
                                TICKER SYMBOL    CLASS A: NTTFX   CLASS B: FGTBX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip art] The fund seeks long-term growth of capital. To pursue this goal, the
fund invests primarily in stocks of foreign and U.S. companies that rely
extensively on technology in their product development or operations. Under
normal circumstances, the fund invests at least 65% of assets in these
companies, and expects to invest in the securities markets of at least three
countries at any one time, potentially including the U.S. Income is a secondary
goal.

PORTFOLIO SECURITIES

[Clip art] The fund invests primarily in foreign and domestic common stocks, and
may invest in warrants, preferred stocks and convertible debt securities. The
fund may invest up to 10% of assets in debt securities of any maturity. These
may include securities rated as low as CC/Ca and their unrated equivalents.
Bonds rated lower than BBB/Baa are considered junk bonds.

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 up to 100% in these securities as a defensive tactic. The fund also may
invest in certain higher-risk securities, including restricted securities, and
may engage in other investment practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. Because the fund concentrates on a single
sector (technology), and because this sector has historically been volatile,
investors should expect above-average volatility.

Also, because the fund invests internationally, it carries additional risks,
including currency, information, natural event and political risks. These risks,
which may make the fund more volatile than a comparable domestic growth fund,
are defined in "More about risk" starting on page 29. The risks of international
investing are higher in emerging markets such as those of Latin America, Asia
and Eastern Europe. To the extent that the fund invests in smaller
capitalization companies or junk bonds, it further increases the chances for
fluctuations in share price and total return. Please read "More about risk"
carefully before investing.

MANAGEMENT/SUBADVISER

[Clip art] Barry J. Gordon and Marc H. Klee lead the fund's management team, as
they have since the fund's inception in 1983. They are principals of American
Fund Advisors, Inc. (AFA), which was the fund's adviser until 1991. Since 1991,
AFA has been the fund's subadviser.

INVESTOR EXPENSES

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

 Management fee(3)                       0.79%     0.79%
 12b-1 fee(4)                            0.30%     1.00%
 Other expenses                          0.42%     0.42%
 Total fund operating expenses           1.51%     2.21%
    

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                  $65      $95      $128      $221
 Class B shares
   Assuming redemption
   at end of period              $72      $99      $138      $237
   Assuming no redemption        $22      $69      $118      $237
    

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) Includes a subadviser fee that will not exceed 0.35% of the fund's net
    assets.
(4) Because of the 12b-1 fee, long-term shareholders may indirectly pay more
    than the equivalent of the maximum permitted front-end sales charge.

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

GOAL AND STRATEGY

[Clip art] The fund seeks long-term growth of capital. To pursue this goal, the
fund invests primarily in stocks of foreign companies. Under normal
circumstances, the fund invests at least 65% of assets in these companies. The
fund maintains a diversified portfolio of company and government securities from
around the world, and generally expects that at any one time it will invest in
the securities markets of at least three non-U.S. countries.

The fund does not maintain a fixed allocation of assets, either with respect to
securities type or to geography. The fund looks for companies of any size whose
earnings show strong growth or that appear to be undervalued.

PORTFOLIO SECURITIES

[Clip art] Under normal circumstances, the fund invests primarily in common
stocks and other equity securities, but may invest in almost any type of
security, foreign or domestic, including preferred and convertible securities,
warrants and investment- grade debt 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 up to 100% in these securities as a defensive tactic. The fund also may
invest in certain higher-risk securities, and may engage in other investment
practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements.

Because it invests internationally, the fund carries additional risks, including
currency, information, natural event and political risks. These risks, which may
make the fund more volatile than a comparable domestic growth fund, are defined
in "More about risk" starting on page 29. The risks of international investing
are higher in emerging markets such as those of Latin America, Asia and Eastern
Europe.

To the extent that the fund invests in smaller capitalization companies or
utilizes higher-risk securities and practices, it takes on further risks that
could adversely affect its performance. Please read "More about risk" carefully
before investing.

MANAGEMENT/SUBADVISER

[Clip art] Miren Etcheverry, John L.F. Wills, and Gerardo J. Espinoza lead the
fund's portfolio management team. Ms. Etcheverry and Mr. Espinoza are senior
vice presidents and joined John Hancock Funds in December 1996, having been in
the investment business since 1978 and 1979, respectively. Mr. Wills is a senior
vice president of the adviser and managing director of the subadviser, John
Hancock Advisers International. He joined John Hancock Funds in 1987 and has
been in the investment business since 1969.

 Total fund operating expenses (after limitation)(3)    1.73%     2.43%
    

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                  $67     $102      $139       $244
 Class B shares
   Assuming redemption
   at end of period              $75     $106      $150       $259
   Assuming no redemption        $25      $76      $130       $259
    

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

   
(1) Except for investments of $1 million or more; see "How sales charges are
    calculated."
(2) Does not include wire redemption fee (currently $4.00).
(3) Reflects the adviser`s agreement to limit expenses (except for 12b-1 and
    transfer agent expenses). Without this limitation, management fees would be
    1.00% for each class, other expenses would be 1.73% for each class and total
    fund operating expenses would be 3.03% for Class A and 3.73% for Class B.
    The adviser may terminate this limitation at any time.
(4) Includes a subadviser fee equal to 0.70% of the fund's net assets.
(5) Because of the 12b-1 fee, long-term shareholders may indirectly pay more
    than the equivalent of the maximum permitted front-end sales charge.

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

GOAL AND STRATEGY

[Clip art] The fund seeks long-term growth of capital. To pursue this goal, the
fund invests primarily in a diversified portfolio of stocks of Pacific Basin
companies. The Pacific Basin includes countries bordering the Pacific Ocean.
Under normal circumstances, the fund invests at least 65% of assets in these
companies, with the balance invested in equities of companies not in the Pacific
Basin countries and in investment-grade debt securities of U.S., Japanese,
Australian and New Zealand issuers.

The fund does not maintain a fixed allocation of assets. The fund may at times
invest less than 65% of assets in Pacific Basin equities.

PORTFOLIO SECURITIES

[Clip art] Under normal circumstances, the fund invests primarily in common
stocks and other equity securities, but may invest in virtually any type of
security, foreign or domestic, including preferred and convertible securities,
warrants and investment- grade debt 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 up to 100% in these securities as a defensive tactic. The fund also may
invest in certain higher-risk securities, and may engage in other investment
practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. Because the fund concentrates on one
region, investors should expect above-average volatility.

Also, because the fund invests internationally, it carries additional risks,
including currency, information, natural event and political risks. These risks,
which may make the fund more volatile than a comparable domestic growth fund,
are defined in "More about risk" starting on page 29. The risks of international
investing are higher in emerging markets, a category that includes many Pacific
Basin countries.

To the extent that the fund utilizes higher-risk securities practices, it takes
on further risks that could adversely affect its performance. Please read "More
about risk" carefully before investing.

MANAGEMENT/SUBADVISERS

[Clip art] The fund's management is carried out jointly by the adviser's
international equities portfolio management team and two subadvisers, Indocam
Asia Advisers Limited and John Hancock Advisers International. Indocam is
majority owned by Caisse Nationale de Credit Agricole, a French banking
institution.

Short-Term Strategic Income Fund
REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST III
                                TICKER SYMBOL    CLASS A: JHSAX   CLASS B: FRSWX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip art] The fund seeks a high level of current income. To pursue this goal,
the fund invests primarily in debt securities issued or guaranteed by:

o  foreign governments and companies including those in emerging markets
o  the U.S. Government, its agencies or instrumentalities
o  U.S. companies

Under normal circumstances, the fund invests assets in all three of these
sectors, but may invest up to 100% in any one sector. The fund maintains an
average portfolio maturity of three years or less.

PORTFOLIO SECURITIES

[Clip art] The fund may invest in all types of debt securities. The fund's U.S.
Government securities may include mortgage-backed securities. The fund may
invest up to 67% of assets in securities rated as low as B and their unrated
equivalents. Bonds rated lower than BBB/Baa are considered junk bonds. However,
the fund maintains an average portfolio quality rating of A, which is an
investment-grade rating.

Because the fund is non-diversified, it may invest more than 5% of assets in
securities of a single issuer, but no more than 25% of assets in the securities
of any one foreign government. The fund also may invest in certain other
investments, including derivatives, and may engage in other investment
practices.

RISK FACTORS

[Clip art] The value of your investment in the fund will fluctuate with changes
in currency exchange rates as well as interest rates. Typically, a rise in
interest rates causes a decline in the market value of fixed income securities.

International investing, particularly in emerging markets, carries additional
risks, including currency information, natural event and political risks. Junk
bonds may carry above-average credit and market risks and mortgage-backed
securities may carry extension and prepayment risks. These risks are defined in
"More about risk" starting on page 29.

To the extent that the fund utilizes higher-risk securities practices, it takes
on further risks that could adversely affect its performance. Please read "More
about risk" carefully before investing.

PORTFOLIO MANAGEMENT

[Clip art] Anthony A. Goodchild, Lawrence J. Daly and Janet L. Clay lead the
portfolio management team. Messrs. Goodchild and Daly are senior vice presidents
and joined John Hancock Funds in July 1994, having been in the investment
business since 1968 and 1972, respectively. Ms. Clay, a vice president, joined
John Hancock Funds in August 1995 and has been in the investment business since
1990.

- --------------------------------------------------------------------------------
 Management fee                          0.65%     0.65%
 12b-1 fee(3)                            0.30%     1.00%
 Other expenses                          0.48%     0.48%
 Total fund operating expenses           1.43%     2.13%
    

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                  $44     $74      $106     $196
 Class B shares
   Assuming redemption
   at end of period              $52     $87      $114     $204
   Assuming no redemption        $22     $67      $114     $204
    

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.

                                    INCOME - SHORT-TERM STRATEGIC INCOME FUND 15
<PAGE>

World Bond Fund
REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST III
                                TICKER SYMBOL    CLASS A: FGLAX   CLASS B: FGLIX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip art] The fund seeks a high total investment return -- a combination of
current income and capital appreciation. To pursue this goal, the fund invests
at least 65% of assets in debt securities issued or guaranteed by:

o  foreign governments and companies including those in emerging markets
o  multinational organizations such as the World Bank
o  the U.S. Government, its agencies or instrumentalities

Under normal circumstances, the fund expects to invest in the securities markets
of at least three countries at any one time, potentially including the U.S. The
fund does not maintain a fixed allocation of assets.

PORTFOLIO SECURITIES

[Clip art] The fund may invest in all types of debt securities of any maturity,
including preferred and convertible securities. Less than 35% of assets may be
invested in junk bonds rated as low as CCC/Caa, or equivalent.

Because the fund is non-diversified, it may invest more than 5% of assets in
securities of a single issuer, but no more than 25% of assets in the securities
of any one foreign government.

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 other investments, including derivatives, and may engage in
other investment practices.

RISK FACTORS

[Clip art] As with most bond funds, the value of your investment in the fund
will fluctuate with changes in interest rates. Typically, a rise in interest
rates causes a decline in the market value of fixed income securities.

International investing, particularly in emerging markets, carries additional
risks, including currency, information, natural event and political risks. Junk
bonds may carry above-average credit and market risks and mortgage-backed
securities may carry extension and prepayment risks. These risks are defined in
"More about risk" starting on page 29.

To the extent that the fund utilizes higher-risk securities practices, it takes
on further risks that could adversely affect its performance. Please read "More
about risk" carefully before investing.

PORTFOLIO MANAGEMENT

[Clip art] Anthony A. Goodchild, Lawrence J. Daly and Janet L. Clay lead the
portfolio management team. Messrs. Goodchild and Daly are senior vice presidents
and joined John Hancock Funds in July 1994, having been in the investment
business since 1968 and 1972, respectively. Ms. Clay, a vice president, joined
John Hancock Funds in August 1995 and has been in the investment business since
1990.

- --------------------------------------------------------------------------------
 Management fee                          0.75%     0.75%
 12b-1 fee(3)                            0.30%     1.00%
 Other expenses                          0.63%     0.63%
 Total fund operating expenses           1.68%     2.38%
    

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                  $61     $96      $132     $235
 Class B shares
   Assuming redemption
   at end of period              $74     $104     $147     $254
   Assuming no redemption        $24      $74     $127     $254
    

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.

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 (all funds)
- --------------------------------------------------------------------------------
 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, there is 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 purchase under the
accumulation and combination privileges. Each investor has an individual
account, but the group's investments are lumped together for sales charge
purposes, making the investors potentially eligible for reduced sales charges.
There is no charge, no obligation to invest (although initial investments must
total at least $250) and individual investors may close their accounts at any
time.
    

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


CDSC waivers As long as Signature Services is notified at the time you sell, the
CDSC for 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
<PAGE>

Waivers for certain investors Class A shares may be offered without front-end

    for non-discretionary accounts 

o   selling brokers and their employees and sales representatives

    products under agreement with John Hancock Funds

o   fund trustees and other individuals who are affiliated with these or other
    John Hancock funds

o   individuals transferring assets from an employee benefit plan into a John
    Hancock fund

o   members of an approved affinity group financial services program

o   certain insurance company contract holders (one-year CDSC usually applies)

   
o   participants in certain retirement plans with at least 100 eligible
    employees (one-year CDSC applies)
    

o   clients of AFA, when their funds are transferred directly to Global
    Technology Fund from accounts managed by AFA

o   certain former shareholders of John Hancock National Aviation & Technology
    Fund and Nova Fund (applies to Global Technology Fund only).

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

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

o  your address of record has changed within the past 30 days

o  you are selling more than $100,000 worth of shares

o  you are requesting payment other than by a check mailed to the address of
   record and payable to the registered owner(s)

You can generally obtain a signature guarantee from the following sources: 

o  a broker or securities dealer

o  a federal savings, cooperative or other type of bank 

o  a savings and loan or other thrift institution

o  a credit union

o  a securities exchange or clearing agency

A notary public CANNOT provide a signature guarantee.

TRANSACTION POLICIES

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

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

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

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

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

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

Exchanges You may exchange shares of one John Hancock fund for shares of the
same class of any other, generally without paying any additional sales charges.
The registration for both accounts involved must be identical. Class B 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.

Foreign currencies Purchases must be made in U.S. dollars. Purchases in foreign
currencies must be con verted, which may result in a fee and delayed execution.

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


24 YOUR ACCOUNT
<PAGE>

Dividends The income funds generally declare income dividends daily and pay them
monthly. These income dividends begin accruing the day after payment is received
by the fund and continue through the day your shares are actually sold. The
growth funds pay income dividends, if any, annually. All funds distribute
capital gains, if any, annually.

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

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

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

Some dividends paid in January may be taxable as if they had been paid the
previous December. Corporations may be entitled to take a dividends-received
deduction for a portion of certain dividends they receive from the growth funds.

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

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

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

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

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

o  Complete the appropriate parts of your account application.

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

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

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

o  Make sure you are not planning to invest more money in this account (buying
   shares during a period when you are also selling shares of the same fund is
   not advantageous to you, because of sales charges).

o  Specify the payee(s). The payee may be yourself or any other party, and there
   is no limit to the number of payees you may have, as long as they are all on
   the same payment schedule.

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

o  Fill out the relevant part of the account application. To add a systematic
   withdrawal plan to an existing account, contact your financial representative
   or Signature Services.

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

BUSINESS STRUCTURE

How the funds are organized Each John Hancock international/global 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 international/global
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").

26 FUND DETAILS
<PAGE>

Accounting compensation The funds (except for Global Technology) 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.
Global Technology pays a $100,000 administration fee to the adviser.

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 Global Rx Fund,International Fund and World Bond
Fund, each fund's investment goal is fundamental and may only be changed with
shareholder approval.

Diversification Except for Global Rx Fund, Short-Term Strategic Income Fund and
World Bond Fund, all of the international/global 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 authorizing annual fees of this type). The 12b-1 fee rates
vary by fund and by share class, according to Rule 12b-1 plans adopted by the
funds. The sales charges and 12b-1 fees paid by investors are detailed in the
fund-by-fund information. The portions of these expenses that are reallowed to
financial services firms are shown on the next page.

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

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

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

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

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

MORE ABOUT RISK

A fund's risk profile is largely defined by the fund's primary 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 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 the performance of a John
Hancock international/global fund will be positive over any period of time --
days, months or years. However, international markets have performed better over
the past two decades than domestic markets.

- --------------------------------------------------------------------------------
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).

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.

Information risk The risk that key information about a security or market is
inaccurate or unavailable.

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

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

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

o  Speculative To the extent that a derivative is not used as a hedge, the fund
   is directly exposed to the risks of that derivative. Gains or losses from
   speculative positions in a derivative may be substantially greater than the
   derivative's original cost.

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

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

Market risk The risk that the market value of a security may move up and down,
sometimes rapidly and unpredictably. These fluctuations may cause a security to
be worth less than it was worth at an earlier time. Market risk may affect a
single issuer, industry, sector of the economy or the market as a whole. Common
to all stocks and bonds and the mutual funds that invest in them.

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

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

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

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

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

ORGANIZATION OF THE FUND

The Fund is a series of the Trust, an open-end investment management company
organized as a Massachusetts business trust in August, 1986 under the laws of
The Commonwealth of Massachusetts. On January 1, 1995, the Fund changed its name
from John Hancock Freedom Global Rx.

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

INVESTMENT OBJECTIVE AND POLICIES

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

The investment objective of the Fund is long-term capital appreciation through
investments in an international portfolio consisting primarily of equity
securities of issuers in the health care industry. Accordingly, the Fund seeks
to increase the value of shareholder investments, and any current income is
incidental to this objective.
    

Under normal conditions, the Fund will invest at least 65% of its total assets
in the securities of health care companies. A "health care" company is one in
which at least 50% of gross revenues are derived from, or 50% of gross assets
are committed to, health care activities as of the end of its last fiscal year
or its most recent publicly available financial statement. The health care
industry is diverse, including companies which design, produce and/or sell
prescription drugs and over-the-counter medicines, drug delivery systems and
medical and analytical instruments; companies which own and/or manage health
care facilities; and companies involved in biotechnology. Because the Fund
concentrates its investments in the health care industry, its performance is
closely tied to conditions in this industry. The types of products and services
comprising this industry tend to become obsolete quickly with the discovery of
more effective medical techniques. Additionally, the companies providing these
services and products are subject to strict government regulation which could
have an unfavorable impact on the price and supply of their services and
products. Because the Fund is non-diversified it will be more susceptible to
adverse developments affecting any single issuer.

The Fund invests in common stocks and in securities convertible into or with
rights to purchase common stock of U.S. and foreign issuers. The value of
convertible securities, while influenced by the level of interest rates, is also
affected by the changing value of the underlying common stock into which the
securities are convertible. The Fund will not purchase any convertible
securities rated below "B" by a major rating agency.

A significant portion of the Fund's investments are expected to be in countries
with developing markets, and in smaller capitalization developing-growth
companies with relatively limited operating histories as publicly traded
companies, and without regard to a record of profits or dividends. Investing in
securities of smaller capitalization developing-growth companies also involves
greater risk and the possibility of greater portfolio price volatility. Among
the reasons for the greater price volatility in these small companies and
unseasoned stocks are the less certain growth prospects of smaller firms, the
lower degree of liquidity in the markets for these stocks and the greater
sensitivity of small companies to changing economic conditions in their
geographic region. Securities of these companies involve higher investment risks


                                       2
<PAGE>

than those normally associated with larger firms due to the greater business
risks of small size and limited product lines, markets, distribution channels
and financial and managerial resources.

Investment in Foreign Securities. The Fund may invest in the securities of
foreign issuers in the form of sponsored and unsponsored 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. Generally, ADRs, in registered form, are designed for use in U.S.
securities markets and EDRs are designed for use in foreign securities markets.
Issuers of unsponsored ADRs are not contractually obligated to disclose material
information including financial information, in the United States.

The securities markets of many countries have in the past moved relatively
independently of one another, due to differing economic, financial, political
and social factors. When markets in fact move in different directions and offset
each other, there may be a corresponding reduction in risk for the Fund's
portfolio as a whole. This lack of correlation among the movements of the
world's securities markets may also affect unrealized gains the Fund has derived
from movements in any one market.

If securities traded in markets moving in different directions are combined into
a single portfolio, such as that of the Fund, total portfolio volatility may be
reduced. Since the Fund may invest in securities denominated in currencies other
than U.S. dollars, changes in foreign currency exchange rates may affect the
value of its portfolio securities. Exchange rates may not move in the same
direction as the securities markets in a particular country. As a result, market
gains may be offset by unfavorable exchange rate fluctuations.

Foreign Currency Transactions. The Fund's foreign currency exchange transactions
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 also
enter into forward foreign currency exchange contracts to enhance return, to
hedge against fluctuations in currency exchange rates affecting a particular
transaction or portfolio position, or as a substitute for the purchase or sale
of a currency or assets denominated in that currency. 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 may elect to hedge less than all of
its foreign portfolio positions as deemed appropriate by the Adviser.

If the Fund purchases a forward contract or sells a forward contract for
non-hedging purposes, its custodian will segregate cash or liquid securities, of
any type or maturity, in a separate account of the Fund in an amount equal to
the value of the Fund's total assets committed to the consummation of such
forward contract. The assets in the segregated account 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 be equal the amount of the Fund's commitment with respect to
such contracts.

Hedging against a decline in the value of a currency does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of such securities decline. Such transactions also preclude the
opportunity for gain if the value of the hedged currency should rise. Moreover,


                                       3
<PAGE>

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

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
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
State 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 favorable or unfavorable 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.

These risks may be intensified in the case of investments in emerging markets or
countries with limited or developing capital markets. These countries are
located in the Asia-Pacific region, Eastern Europe, Latin and South America and
Africa. Security prices in these markets can be significantly more volatile than
in more developed countries, reflecting the greater uncertainties of investing
in less established markets and economies. Political, legal and economic
structures in many of these emerging market countries may be undergoing
significant evolution and rapid development, and they may lack the social,
political, legal and economic stability characteristic 


                                       4
<PAGE>

of more developed countries. Emerging market countries may have failed in the
past to recognize private property rights. They may have relatively unstable
governments, present the risk of nationalization of businesses, restrictions on
foreign ownership, or prohibitions on repatriation of assets, and may have less
protection of property rights than more developed countries. Their economies may
be predominantly based on only a few industries, may be highly vulnerable to
changes in local or global trade conditions, and may suffer from extreme and
volatile debt burdens or inflation rates. Local securities markets may trade a
small number of securities and may be unable to respond effectively to increases
in trading volume, potentially making prompt liquidation of substantial holdings
difficult or impossible at times. The Fund may be required to establish special
custodial or other arrangements before making certain investments in those
countries. Securities of issuers located in these countries may have limited
marketability and may be subject to more abrupt or erratic price movements.

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

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

Reverse Repurchase Agreements. The Fund may also enter into reverse repurchase
agreements which involve the sale of U.S. Government securities held in its
portfolio to a bank with an agreement that the Fund will buy back the securities
at a fixed future date at a fixed price plus an agreed amount of "interest"
which may be reflected in the repurchase price. Reverse repurchase agreements
are considered to be borrowings by the Fund. Reverse repurchase agreements
involve the risk that the market value of securities purchased by the Fund with
proceeds of the transaction may decline below the repurchase price of the
securities sold by the Fund which it is obligated to repurchase. The Fund will
also continue to be subject to the risk of a decline in the market value of the
securities sold under the agreements because it will reacquire those securities
upon effecting their repurchase. To minimize various risks associated with
reverse repurchase agreements, the Fund will establish and maintain with the
Fund's custodian a separate account consisting of liquid securities, of any type
or maturity, in an amount at least equal to the repurchase prices of these
securities (plus accrued interest thereon) under such agreements. In addition,
the Fund will not borrow money or enter into reverse repurchase agreements
except from banks as a temporary measure for extraordinary emergency purposes in
amounts not to exceed 33 1/3% of the value of the Fund's total assets (including
the amount borrowed) taken at market value. The Fund will not use leverage to
attempt to increase income. The Fund will not purchase securities while
outstanding borrowings exceed 5% of the Fund's total assets. The Fund will enter
into reverse repurchase agreements only with federally insured banks which are
approved in advance as being creditworthy by the Trustees. Under procedures
established by the Trustees, the Adviser will monitor the creditworthiness of
the banks involved.

Restricted Securities. The Fund may purchase securities that are not registered
("restricted securities") under the Securities Act of 1933 ("1933 Act"),
including commercial paper issued in 


                                       5
<PAGE>

reliance on Section 4(2) of the 1933 Act and securities offered and sold to
"qualified institutional buyers" under Rule 144A under the 1933 Act. The Fund
will not invest more than 15% of its net assets in illiquid investments. If the
Trustees determine, based upon a continuing review of the trading markets for
specific Section 4(2) paper or Rule 144A securities, that they are liquid, they
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
and monitoring the liquidity of restricted securities. The Trustees, however,
will retain sufficient oversight and be ultimately responsible for the
determinations. The Trustees will carefully monitor the Fund's 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, Securities Indices and Currency. The Fund may purchase
and write (sell) call and put options on any securities in which it may invest,
on any securities index based on securities in which it may invest or on any
currency in which Fund investments may be denominated. These options may be
listed on national domestic securities exchanges or foreign securities exchanges
or traded in the over-the-counter market. The Fund may write covered put and
call options and purchase put and call options to enhance total return, as a
substitute for the purchase or sale of securities or currency, or to protect
against declines in the value of portfolio securities and against increases in
the cost of securities to be acquired.

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

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

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


                                       6
<PAGE>

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

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

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

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

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

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


                                       7
<PAGE>

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

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

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

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

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

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

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

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


                                       8
<PAGE>

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

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

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

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

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

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

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

Other Considerations. The Fund will engage in futures and related options
transactions either for bona fide hedging purposes or to seek to increase total
return as permitted by the CFTC. To the 


                                       9
<PAGE>

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

To the extent that the Fund engages in nonhedging transactions in futures
contracts and options on futures, the aggregate initial margin and premiums
required to establish these nonhedging positions will not exceed 5% of the net
asset value of the Fund's portfolio, after taking into account unrealized
profits and losses on any such positions and excluding the amount by which such
options were in-the-money at the time of purchase. 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 qualifications 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 or currencies, require the Fund to
establish with the custodian a segregated account consisting of cash or liquid
securities in an amount equal to the underlying value of such contracts and
options.

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

Perfect correlation between the Fund's futures positions and portfolio positions
will be impossible to achieve. There are no futures contracts based upon
individual securities, except certain U.S. Government securities. The only
futures contracts available to hedge the Fund's portfolio are various futures on
U.S. Government securities, securities indices and foreign currencies. In the
event of an imperfect correlation between a futures position and a portfolio
position which is intended to be protected, the desired protection may not be
obtained and the Fund may be exposed to risk of loss. In addition, it is not
possible to hedge fully or protect against currency fluctuations affecting the
value of securities denominated in foreign currencies because the value of such
securities is likely to fluctuate as a result of independent factors not related
to currency fluctuations.

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

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

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

Short Sales. The Fund may engage in short sales in order to profit from an
anticipated decline in the value of a security. The Fund may also engage in
short sales to attempt to limit its exposure to a possible market decline in the
value of its portfolio securities through short sales of securities which the
Adviser believes possess volatility characteristics similar to those being
hedged. To effect such a transaction, the Fund must borrow the security sold
short to make delivery to the buyer. The Fund then is obligated to replace the
security borrowed by purchasing it at the market price at the time of
replacement. Until the security is replaced the Fund is required to pay to the
lender any accrued interest and may be required to pay a premium.

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

Under applicable guidelines of the staff of the Securities and Exchange
Commission (the "SEC"), if the Fund engages in short sales of the type referred
to in non-fundamental Investment Restriction No. (c) (ii) and (iii) below, it
must put in a segregated account (not with the broker) an amount of cash or U.S.
Government securities equal to the difference between (1) the market value of
the securities sold short at the time they were sold short and (2) any cash or
U.S. Government securities required to be deposited as collateral with the
broker in connection with the short sale (not including the proceeds from the
short sale). In addition, until the Fund replaces the borrowed security, it must
daily maintain the segregated account at such a level that the amount deposited
in it plus the amount deposited with the broker as collateral will equal the
current market value of the securities sold short. Except for short sales
against the box, the amount of the Fund's net assets that may be committed to
short sales is limited and the securities in which short sales are made must be
listed on a national securities exchange.

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


                                       11
<PAGE>

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

The Fund does not intend to enter into short sales (other than those "against
the box") if immediately after such sale the aggregate of the value of all
collateral plus the amount in such segregated account exceeds 5% of the value of
the Fund's net assets. A short sale is "against the box" to the extent that the
Fund contemporaneously owns or has the right to obtain at no added cost
securities identical to those sold short.

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

When the Fund engages in forward commitment and when-issued transactions, it
relies on the seller to consummate the transaction. The failure of the issuer or
seller to consummate the transaction may result in the Fund's losing the
opportunity to obtain a price and yield considered to be advantageous. The
purchase of securities on a when-issued or forward commitment basis also
involves a risk of loss if the value of the security to be purchased declines
prior to the settlement date.

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

   
Short-Term Trading and Portfolio Turnover. Short-term trading means the purchase
and subsequent sale of a security after it has been held for a relatively brief
period of time. The Fund may engage in short-term trading in response to stock
market conditions, changes in interest rates or other economic trends and
developments, or to take advantage of yield disparities between various fixed
income securities in order to realize capital gains or improve income. Over the
past several years, political and economic events in foreign countries and in
the health care industry have affected the Fund's geographic allocation of
assets. A high rate of portfolio turnover (100% or more) involves
correspondingly greater brokerage expenses. The Fund's portfolio turnover rate
is set forth in the table under the caption "Financial Highlights" in the
Prospectus.
    

INVESTMENT RESTRICTIONS

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


                                       12
<PAGE>

The Fund may not:

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

(2) Borrow money, except from banks as a temporary measure for extraordinary
emergency purposes in amounts not to exceed 33 1/3% of the value of the Fund's
total assets (including the amount borrowed) taken at market value. The Fund
will not use leverage to attempt to increase income. The Fund will not purchase
securities while outstanding borrowings exceed 5% of the Fund's total assets.

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

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

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

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

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

(8) Purchase securities, other than obligations of the U.S. Government or any of
its agencies or instrumentalities, if such purchase would cause 25% or more of
the value of the Fund's total assets to be invested in securities of issuers
conducting their principal business activities in the same industry, except that
the Fund shall invest at least 25% of the value of its total assets in
securities of issuers in the health care industry.

   
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) Participate on a joint or joint-and-several basis in any securities trading
account. The "bunching" of orders for the sale or repurchase of marketable
portfolio securities with other 
    


                                       13
<PAGE>

   
accounts under the management of the Adviser to save commissions or to average
prices among them is not deemed to be participation in a joint securities
trading account.

(b) Purchase securities on margin except that the Fund may obtain such
short-term credits as may be necessary for the clearance of purchases and sales
of securities.

(c) Make short sales of securities or maintain a short position unless (i) at
all times when a short position is open the Fund owns an equal amount of such
securities or securities convertible into or exchangeable, without payment of
any further consideration, for securities of the same issue as, and equal in
amount to, the securities sold short; (ii) for the purpose of hedging the Fund's
exposure to an actual or anticipated market decline in the value of its
investments; or (iii) in order to profit from an anticipated decline in the
value of a security.

(d) 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.

(e) 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 values of the Fund's assets will not be
considered a violation of the restriction.

THOSE RESPONSIBLE FOR MANAGEMENT

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

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

Net Asset Value                           Annual Rate
- ---------------                           -----------
First $200,000,000                           0.80%
Amount over $200,000,000                     0.70%

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

Securities held by the Fund may also be held by other funds or investment
advisory clients for which the Adviser or 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 other
funds or clients are selling the same security. If opportunities for purchase or
sale of securities by the Adviser for the Fund or for other funds or clients for
which the Adviser renders investment advice arise for consideration at or about
the same time, transactions in such securities will be made, insofar as
feasible, for the respective funds or clients in a manner deemed equitable to
all of them. To the extent that transactions on behalf of more than one client
of the Adviser or 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 Advisory Agreement relates, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
the Adviser in the performance of its duties or from reckless disregard of the
obligations and duties under the Advisory Agreement.

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

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

For the fiscal years ended August 31, 1996 and 1995, the Adviser received fees
of $457,352 and $190,775, respectively. For the period from September 1, 1996 to
October 31, 1996, and for the fiscal year ended October 31, 1997, the Adviser
received fees of $112,225 and $725,408, respectively. In 1996, the Trustees
changed the fiscal year-end of the Fund to October 31, 1996.
    


                                       24

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 period from September 1, 1996 to October 31, 1996,
the Fund paid the Adviser $2,630 for services under this agreement. For the
fiscal year ended October 31, 1997, the Fund paid the Adviser $16,625 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

   
The Fund has a Distribution Agreement contract with John Hancock Funds. Under
the agreement, John Hancock Funds is obligated to use its best efforts to sell
shares on behalf 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. In the case of Class B shares, the broker
receives compensation immediately but John Hancock Funds is compensated on a
deferred basis. John Hancock Funds may pay extra compensation to financial
services firms selling large amounts of fund shares. This compensation would be
calculated as a percentage of fund shares sold by the firm.

Total underwriting commissions for sales of the Fund's Class A shares for the
fiscal periods ended October 31, 1997, September 1, 1996 to October 31, 1996,
August 31, 1996 and August 31, 1995 were $288,889, $105,287, $471,313 and
$133,497, respectively, and $44,643, $36,747, $71,002 and $45,279, respectively,
were retained by John Hancock Funds in 1997, 1996 and 1995, respectively. The
remainder of the underwriting commissions were reallowed to dealers.

The Fund's Trustees adopted Distribution Plans with respect to Class A and Class
B shares (the "Plans"), pursuant to Rule 12b-1 under the Investment Company Act
of 1940. Under the Plans, the Fund will pay distribution and service fees at an
aggregate annual rate of up to 0.30% and 1.00%, respectively, of the Fund's
average daily net assets attributable to shares of that class. However, the
service fee will not exceed 0.25% of the Fund's average daily net assets
attributable to each class of shares. The distribution fee 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 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 Class B Plan
expenses at any time. For the fiscal year ended October 31, 1997, an aggregate
of $466,209 of Distribution Expenses or 1.06% of the average net assets 
    


                                       25
<PAGE>

of the 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 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 such Plans.

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

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

Amounts paid to John Hancock Funds by any class of shares of the Fund will not
be used to pay the expenses incurred with respect to any other class of shares
of the Fund; provided, however, that expenses attributable to the Fund as a
whole will be allocated, to the extent permitted by law, according to a formula
based upon gross sales dollars and/or average daily net assets of each such
class, as may be approved from time to time by vote of a majority of 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 Fund.

   
For the fiscal year ended October 31, 1997, the Fund paid John Hancock Funds the
following amounts of expenses in connection with their services for the Fund:

                                  Expense Items

NET ASSET VALUE

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

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

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

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

The NAV for each fund and class is determined each business day at the close of
regular trading on the New York Stock Exchange (typically 4:00 p.m. Eastern
Time) by dividing a class's net asset 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 the 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 shares 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 cumulate current purchases with the
greater of the current value (at offering price) of the Class A shares of the
Fund, owned 


                                       27
<PAGE>

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.*

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:


                                       28
<PAGE>

            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 of all John
Hancock funds which carry a sales charge already held by such person. Class A
shares of John Hancock money market funds will only be eligible for the
accumulation privilege if the investor has previously paid a sales charge on the
amount of those shares.

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

Letter of Intention. Reduced sales charges are also applicable to investments
made pursuant to a Letter of Intention (the "LOI"), which should be read
carefully prior to its execution by an investor. The Fund offers two options
regarding the specified period for making investments under the LOI. All
investors have the option of making their investments over a specified period of
thirteen (13) months. Investors who are using the Fund as a funding medium for a
retirement plan, however, may opt to make the necessary investments called for
by the LOI over a forty-eight (48) month period. These retirement plans include
IRAs, SEP, SARSEP, 401(k), 403(b) (including TSAs), SIMPLE IRA, SIMPLE 401(k),
Money Purchase Pension, Profit Sharing and Section 457 plans. Such an investment
(including accumulations and combinations) must aggregate $50,000 or more
invested during the specified period from the date of the LOI or from a date
within ninety (90) days prior thereto, upon written request to Signature
Services. The sales charge applicable to all amounts invested under the LOI is
computed as if the aggregate amount intended to be invested had been invested
immediately. If such aggregate amount is not actually invested, the difference
in the sales charge actually paid and the sales charge payable had 
    


                                       29
<PAGE>

the LOI not been in effect is due from the investor. However, for the purchases
actually made within the specified period (either 13 or 48 months) the sales
charge applicable will not be higher than that which would have applied
(including accumulations and combinations) had the LOI been for the amount
actually invested.

The LOI authorizes Signature Services to hold in escrow sufficient Class A
shares (approximately 5% of the aggregate) to make up any difference in sales
charges on the amount intended to be invested and the amount actually invested,
until such investment is completed within the specified period, at which time
the 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 the sales charge as may be due. By
signing the LOI, the investor authorizes Signature Services to act as his or her
attorney-in-fact to redeem any escrowed Class A shares and adjust the sales
charge, if necessary. A LOI does not constitute a binding commitment by an
investor to purchase or by the Fund to sell any additional Class A shares and
may be terminated at any time.

DEFERRED SALES CHARGE ON CLASS B SHARES

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

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

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

The amount of the CDSC, if any, will vary depending on the number of years from
the time of payment for the purchase of Class B shares until the time of
redemption of such shares. Solely for purposes of determining the number 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.
    

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.


                                       30
<PAGE>

   
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:

      o Proceeds of 50 shares redeemed at $12 per shares (50 x 12)   $600.00
      o*Minus Appreciation ($12 - $10) x 100 shares                  (200.00) 
      o Minus proceeds of 10 shares not subject to CDSC
        (dividend reinvestment)                                      (120.00)
                                                                     ------- 
      o Amount subject to CDSC                                       $280.00

      *The appreciation is based on all 100 shares in the lot not just the
      shares being redeemed.

Proceeds from the CDSC are paid to John Hancock Funds and are used in whole or
in part by John Hancock Funds to defray its expenses related to providing
distribution-related services to the Fund in connection with the sale of the
Class B 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.

*     Redemption 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,

SPECIAL REDEMPTIONS

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

ADDITIONAL SERVICES AND PROGRAMS

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

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

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

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

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

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

   
Systematic Withdrawal Plan. The Fund permits the establishment of a Systematic
Withdrawal Plan. Payments under this plan represent proceeds arising from the
redemption of Fund shares which 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 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 
    


                                       34
<PAGE>

shareholder, or to discontinue the availability of such plan in the future. The
shareholder may terminate the plan at any time by giving proper notice to
Signature Services.

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

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

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

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

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

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

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

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

   
Retirement plans participating in Merrill Lynch's servicing programs:

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

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

DESCRIPTION OF THE FUND'S SHARES

The Trustees of the Trust are responsible for the management and supervision of
the Fund. The Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of the Fund without
par value. Under the Declaration of Trust, the Trustees have the authority to
create and classify shares of beneficial interest in separate series, without
further action by shareholders. As of the date of this Statement of Additional
Information, the Trustees have authorized shares of the Fund and two 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 the Fund,
or any new series of the Trust, into one or more classes. As of the date of this
Statement of Additional Information, the Trustees have authorized the issuance
of two classes of shares of the Fund, designated as Class A and Class B.

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

   
Dividends paid by the Fund, if any, with respect to each class of shares will be
calculated in the same manner, at the same time and on the same day and will be
in the same amount, except for differences resulting from the facts that (i) the
distribution and service fees relating to Class A and Class B shares will be
borne exclusively by that class (ii) Class B shares will pay higher distribution
and service fees than Class A shares and (iii) each of Class A and Class B
shares will bear any other class expenses properly allocable to that 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. No interest will be paid on
uncashed dividend or redemption checks.
    

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

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

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


                                       36

The Fund reserves the right to reject any application which conflicts with the
Fund's internal policies or the policies of any regulatory authority. John
Hancock Funds does not accept credit card checks. Use of information provided on
the account application may be used by the Fund to verify the accuracy of the
information or for background or financial history purposes. A joint account
will be administered as a joint tenancy with right of survivorship, unless the
joint owners notify Signature Services of a different intent. A shareholder's
account is governed by the laws of The Commonwealth of Massachusetts.
    

TAX STATUS

   
Each series of the Trust, including the Fund, is treated as a separate entity
for tax purposes. The Fund has qualified as a "regulated investment company"
under Subchapter M of the Internal Revenue Code of 1986, as amended (the
"Code"), and intends to continue to so qualify for each taxable year. As such
and by complying with the applicable provisions of the Code regarding the
sources of its income, the timing of its distributions, and the diversification
of its assets, the Fund will not be subject to Federal income tax on its taxable
income (including net realized capital gains) which is distributed to
shareholders in accordance with the timing requirements of the Code.

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

Distributions  from the  Fund's  current or  accumulated  earnings  and  profits
("E&P") will be taxable  under the Code for investors who are subject to tax. If
these  distributions  are  paid  from the  Fund's  "investment  company  taxable
income," they will be taxable as ordinary income;  and if they are paid from the
Fund's "net capital  gain," they will be taxable as capital  gain.  (Net capital
gain is the excess (if any) of net  long-term  capital gain over net  short-term
capital loss,  and investment  company  taxable income is all taxable income and
capital  gains,  other than those  gains and losses  included in  computing  net
capital gain,  after  reduction by deductible  expenses.) As a result of federal
tax legislation enacted on August 5, 1997 (the "Act"), gain recognized after May
6, 1997 from the sale of a capital asset is taxable to individual (noncorporate)
investors at different  maximum  federal income tax rates,  depending  generally
upon the tax holding period for the asset, the federal income tax bracket of the
taxpayer,  and the dates  the  asset was  acquired  and/or  sold.  The  Treasury
Department  has  issued  guidance  under the Act that  enables  the Fund to pass
through to its  shareholders  the benefits of the capital gains rates enacted in
the Act.  Shareholders  should  consult  their own tax  advisers  on the correct
application  of  these  new  rules  in  their  particular  circumstances.   Some
distributions  may be paid in January but may be taxable to  shareholders  as if
they had been  received on December 31 of the previous  year.  The tax treatment
described above will apply without regard to whether  distributions are received
in cash or reinvested in additional shares of the Fund.
    

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

   
Foreign exchange gains and losses realized by the Fund in connection with
certain transactions involving foreign currency-denominated debt securities,
certain foreign currency options, foreign currency forward contracts, foreign
currencies, or payables or receivables denominated in a 
    


                                       37
<PAGE>

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

If the Fund invests in stock (including an option to acquire stock such as is
inherent in a convertible bond) of certain foreign corporations that receive at
least 75% of their annual gross income from passive sources (such as interest,
dividends, certain rents and 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 these
passive foreign investment 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. An election may be
available to ameliorate these adverse tax consequences, but could require the
Fund to recognize taxable income or gain without the concurrent receipt of cash.
These investments could also result in the treatment of associated capital gains
as ordinary income. The Fund may limit and/or manage its investments in passive
foreign investment companies or make an available election to minimize its tax
liability or maximize its return from these investments.

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

Certain of options, futures, and forward currency contracts undertaken by the
Fund may cause the Fund to recognize gains or losses from marking to market even
though its positions have not been sold or terminated and may affect the
character as long-term or short-term (or, in the case of foreign currency
contracts, as ordinary income or loss) and timing of some capital gains and
losses realized by the Fund. Additionally, the Fund may be required to recognize
gain, but not loss, if an option, short sale or other transaction is treated as
a constructive sale of an appreciated financial position in the Fund's
portfolio. Also, certain of the Fund's losses on transactions involving options,
futures, or forward contracts, and/or offsetting or successor portfolio
positions may be deferred rather than being taken into account currently in
calculating the Fund's taxable income or gains. Certain of such transactions may
also cause the Fund to dispose of investments sooner than would otherwise have
occurred. These transactions may therefore affect the amount, timing and
character of the Fund's distributions to shareholders. The Fund will take into
account the special tax rules (including consideration of available elections)
applicable to options, futures or forward contracts in order to seek to minimize
any potential adverse tax consequences.

The amount of the Fund's net realized capital gains, if any, in any given year
will vary depending upon the Adviser's current investment strategy and whether
the Adviser believes it to be in the best interest of the Fund to dispose of
portfolio securities and/or engage in options, futures or forward transactions
that will generate capital gains. At the time of an investor's purchase of Fund
shares, a portion of the purchase price is often attributable to realized or
unrealized appreciation in the Fund's portfolio or undistributed taxable income
of the Fund. Consequently, subsequent distributions on those shares from such
appreciation or income may be taxable to such investor even if the net asset
value of the investor's shares is, as a result of the distributions, reduced
    


                                       38
<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 or other distribution of shares of the Fund (including by
exercise of the exchange privilege) in a transaction that is treated as a sale
for tax purposes, a shareholder may realize a taxable gain or loss depending
upon the amount of the proceeds and the investor's basis in his shares. Such
gain or loss will be treated as capital gain or loss if the shares are capital
assets in the shareholder's hands. A sales charge paid in purchasing Class A
shares of the Fund cannot be taken into account for purposes of determining gain
or loss on the redemption or exchange of such shares within 90 days after their
purchase to the extent Class A shares of the Fund or another John Hancock fund
are subsequently acquired without payment of a sales charge pursuant to the
reinvestment or exchange privilege. This disregarded charge will result in an
increase in the shareholder's tax basis in the shares subsequently acquired.
Also, any loss realized on a redemption or exchange may be disallowed to the
extent the shares disposed of are replaced with other shares of the Fund within
a period of 61 days beginning 30 days before and ending 30 days after the shares
are disposed of, such as pursuant to automatic dividend reinvestments. In such a
case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss. Any loss realized upon the redemption of shares with a tax
holding period of six months or less will be treated as a long-term capital loss
to the extent of any amounts treated as distributions of long-term capital gain
with respect to such shares. Shareholders should consult their own tax advisers
regarding their particular circumstances to determine whether a disposition of
Fund shares is properly treated as a sale for tax purposes, as is assumed in the
foregoing discussion. Also, future Treasury Department guidance issued to
implement the Act may contain additional rules for determining the tax treatment
of sales of Fund shares held for various periods, including the treatment of
losses on the sales of shares held for six months or less that are
recharacterized as long-term capital losses, as described above.

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

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

For purposes of the dividends-received deduction available to corporations,
dividends received by the Fund, if any, from U.S. domestic corporations in
respect of any share of stock held by the Fund, for U.S. Federal income tax
purposes, for at least 46 days (91 days in the case of certain preferred stock)
during a prescribed period extending before and after each such dividend and
    


                                       39
<PAGE>

   
distributed and properly designated by the Fund may be treated as qualifying
dividends. Corporate shareholders must meet the holding period requirement
stated above with respect to their Fund shares of the Fund for each dividend in
order to qualify for the deduction and, if they have any debt that is deemed
under the Code directly attributable to such shares, may be denied a portion of
the dividends received deduction. The entire qualifying dividend, including the
otherwise-deductible amount, will be included in determining alternative minimum
tax liability, if any. Additionally, any corporate shareholder should consult
its tax adviser regarding the possibility that its tax basis in its shares may
be reduced, for Federal income tax purposes, by reason of "extraordinary
dividends" received with respect to the shares and, to the extent such basis
would be reduced below zero, that current recognition of income would be
required.

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

If the Fund makes this election, shareholders may then deduct such pro rata
portions of qualified foreign taxes in computing their taxable income, 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 shares 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 the Fund files the election
described above, its shareholders will be notified of the amount of (i) each
shareholder's pro rata share of qualified foreign taxes paid by the Fund and
(ii) the portion of Fund dividends which represents income from each foreign
country. If the Fund cannot or does not make this election, the Fund will deduct
the foreign taxes it pays in determining the amount it has available for
distribution to shareholders, and shareholders will not include these foreign
taxes in their income, nor will they be entitled to any tax deductions or
credits with respect to such taxes.

   
The 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 or constructive sale rules applicable to certain options, futures,
forwards, short sales or other transactions may also require the Fund to
recognize income or gain without a concurrent receipt of cash. Additionally,
some countries restrict repatriation which may make it difficult or impossible
for the Fund to obtain cash corresponding to its earnings or assets in those
countries. However, the Fund must distribute to shareholders for each taxable
year substantially all of its net income and net capital gains, including such
income or gain, to qualify as a regulated investment company and avoid liability
for any federal income or excise tax. Therefore, the Fund may have to dispose of
its portfolio securities under disadvantageous circumstances to generate cash,
or borrow cash, to satisfy these distribution requirements.
    


                                       40
<PAGE>

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

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

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 distribution 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 non-resident alien withholding tax at the rate of
30% (or a lower rate under an applicable tax treaty) on amounts treated as
ordinary dividends from the Fund and, unless an effective IRS Form W-8 or
authorized substitute for Form W-8 is on file, to 31% backup withholding on
certain other payments from the Fund. Non-U.S. investors should consult their
tax advisers regarding such treatment and the application of foreign taxes to an
investment in the Fund.

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

CALCULATION OF PERFORMANCE

   
The average annual total return on Class A shares of the Fund for the 1 year and
5 year periods ended October 31, 1997 and since commencement of operations on
October 1, 1991 was 20.30%, 16.95% and 20.05%, respectively. The average annual
total return on Class B shares of the Fund for the 1 year period ended October
31, 1997 and since commencement of operations on March 7, 1994 was 20.76% and
16.93%, respectively.
    

Total return is computed by finding the average annual compounded rate of return
over the 1 year, 5 year and life-of-fund periods that would equate the initial
amount invested to the ending redeemable value according to the following
formula:

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

P =         a hypothetical initial investment of $1,000
T =         average annual total return
n =         number of years
ERV =       ending redeemable value of a hypothetical $1,000 investment made at
            the beginning of the 1 year, 5 year and life-of-fund periods.

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

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

From time to time, in reports and promotional literature, the Fund's total
return will be compared to indices of mutual funds, such as Lipper Analytical
Services, Inc.'s "Lipper- Mutual Performance Analysis," a monthly publication
which tracks net assets and total return on 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, may also be
utilized. The Fund's promotional and sales literature may make reference to the
Fund's "beta". Beta is a 


                                       42
<PAGE>

reflection of the market related risks 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 officers of the Adviser pursuant
to recommendations made by an investment committee of the Adviser, which
consists of officers and directors of the Adviser and officers and Trustees who
are interested persons of the Trust. Orders for purchases and sales of
securities are placed in a manner, which, in the opinion of the officers 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 maker 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
foreign transactions are generally higher than the negotiated commission rates
available in the U.S. There is generally less government supervision and
regulation of foreign stock exchanges and broker-dealers than in the U.S.

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

   
To the extent consistent with the foregoing, the Fund will be governed in the
selection of broker 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, and their value
and expected contribution to the performance of the Fund. It is not possible to
place a dollar value on information and services to be received from brokers and
dealers, since it is only supplementary to the research efforts of the Adviser.
The receipt of research information is not expected to reduce significantly the
expenses of the Adviser. The research information and statistical assistance
furnished by brokers and dealers may benefit the Life Company or other advisory
clients of the Adviser, and, conversely, brokerage commissions and spreads paid
by other advisory clients of the Adviser may result in research information and
statistical assistance beneficial to the Fund. The Fund will make no commitment
to allocate portfolio transactions upon any prescribed basis. While the
Adviser's officers will be primarily responsible for the allocation of the
Fund's brokerage business, the policies 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
    


                                       43
<PAGE>

   
Trustees. For the years ended August 31, 1995 and 1996, the Fund paid negotiated
brokerage commissions in the amount of $21,243 and $77,611, respectively. For
the period from September 1, 1996 to October 31, 1996, the Fund paid negotiated
commissions in the amount of $31,063 and for the fiscal year ended October 31,
1997, the Fund paid negotiated commissions of $94,269.

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. For the fiscal year ended October 31,
1997, the Fund directed commissions in the amount of $12,184 to compensate to
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. For the
period from September 1, 1996 to October 31, 1996, and October 31, 1997, the
Fund paid no brokerage commissions to 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
with comparable transactions involving similar securities being purchased or
sold. A transaction would not be placed with an Affiliated Broker if the Fund
would have to pay a commission rate less favorable than the Affiliated Broker's
contemporaneous charges for comparable transactions for its other most favored,
but unaffiliated, customers except for accounts for which the Affiliated Broker
acts as clearing broker for another 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 Broker, 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 Broker as a basis for
negotiating commissions at a rate higher than that determined in accordance with
the above criteria.

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

                                   APPENDIX A

                          DESCRIPTION OF BOND RATINGS 1

Moody's Bond Ratings

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

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

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

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

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

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

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

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

<PAGE>

Standard & Poor's Bond Ratings

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

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

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

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

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

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

COMMERCIAL PAPER RATINGS

Moody's Commercial Paper Ratings

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

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

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

Standard & Poor's Commercial Paper Ratings

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

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

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

ORGANIZATION OF THE FUND

The Fund is a series of the Trust, an open-end investment management company
organized as a Massachusetts business trust in August, 1986 under the laws of
The Commonwealth of Massachusetts. On October 1, 1992, the Fund changed its name
from John Hancock World Fund - Pacific Basin Equities Portfolio to John Hancock
Freedom Pacific Basin Equities Fund. As of January 1, 1994, the word "Freedom"
was deleted from the Fund's name.

John Hancock Advisers, Inc. (the "Adviser") is the Fund's investment adviser and
is solely responsible for advising the Fund with respect to investments in the
U.S. and Canada. The Adviser is an indirect, wholly-owned subsidiary of John
Hancock Mutual Life Insurance Company (the "Life Company"), a Massachusetts life
insurance company chartered in 1862, with national headquarters at John Hancock
Place, Boston, Massachusetts.

   
The Fund has two Subadvisers: Indocam Asia Advisers Ltd. ("IAAL") and John
Hancock Advisers International Limited ("JHAI") (collectively, the
"Subadvisers"). IAAL is organized under the laws of Hong Kong and indirectly
owned by Caisse Nationale de Credit Agricole.  Together IAAL and JHAI, a
London based wholly owned subsidiary of the Adviser, are responsible for
providing advice to the Fund with respect to investments other than in the
U.S. and Canada, subject to the review of the Trustees and overall
supervision of the Adviser.
    

INVESTMENT OBJECTIVE AND POLICIES

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

The Fund's investment objective is to achieve long-term capital appreciation
through investment in a diversified portfolio of equity securities of issuers
located in countries of the Pacific Basin. These investments will consist of (1)
securities of companies traded principally on stock exchanges in Pacific Basin
countries; (2) securities of companies deriving at least 50% of their total
revenue from goods produced, sales made or services performed in Pacific Basin
countries; (3) securities of companies that are organized under the laws of
Pacific Basin countries, which are publicly traded on recognized securities
exchanges outside these countries; and (4) securities of investment companies
and trusts that invest principally in the foregoing. The Pacific Basin is
defined as those countries bordering on the Pacific Ocean. The principal Pacific
Basin countries in which the Fund's securities are issued and traded are
Australia, Canada, China, Hong Kong, Indonesia, Japan, Korea, Malaysia, New
Zealand, the Philippines, Singapore, Taiwan, Thailand, Vietnam and the United
States.
    

Under normal conditions, the Fund will invest at least 65% of its total assets
in Pacific Basin corporate common stock and other equity securities (consisting
of common stock, warrants and securities convertible into common stock). The
balance of the Fund's assets will be invested in (1) equity securities of
issuers located in Asian countries not in the Pacific Basin (including India,
Pakistan, Sri Lanka and Bangladesh) and (2) investment grade debt securities
(i.e., rated BBB, Baa or higher by Standard & Poor's Ratings Group or Moody's
Investors Services, Inc., or, if unrated by either such service, determined to
be of comparable quality by the Adviser or a Subadviser) of U.S., Japanese,
Australian and New Zealand companies and governments and bank certificates of
deposit. Debt securities rated BBB or Baa and unrated securities of equivalent
quality are considered medium-grade obligations with speculative
characteristics, and 


                                       -2-
<PAGE>

adverse economic conditions or changing circumstances may weaken the issuer's
capacity to pay interest and repay principal.

The Fund has not established any limitations on the allocation of investments
among the Pacific Basin countries. The portion of the Fund's assets to be
allocated to each of the Pacific Basin countries will be determined by the
Trustees based on recommendations of the Adviser, in consultation with the
Subadvisers, as described under the caption "Those Responsible for Management."
In making this allocation recommendation, the Adviser and the Subadvisers will
consider several factors, including the relative economic growth and potential
of the various economies and securities markets, expected levels of inflation,
governmental policies influencing business conditions, regulatory and tax
considerations, the domestic and international strength of the leading
industrial sectors and currency stability relative to the U.S. When the Adviser
and the Subadvisers believe that investment conditions are unfavorable, they may
recommend a temporary reduction in the proportion of assets assigned to Pacific
Basin countries and investment of a higher than normal proportion in the debt
and other securities described above.

Under normal conditions, up to 35% of the Fund's total assets may be held in
cash or investment grade short-term securities and repurchase agreements
(denominated in U.S. dollars) to meet anticipated redemptions of the Fund's
shares. When the Adviser or Sub- Advisers believe it is appropriate to maintain
a defensive position, any of them may temporarily maintain all or any part of
the Fund's assets in money market instruments, including but not limited to
governmental obligations, certificates of deposit, bankers' acceptances,
commercial paper and investment grade short-term corporate debt securities, cash
and repurchase agreements. Any of the foregoing, including cash, may be
denominated in U.S. or foreign currencies and may be obligations of foreign
issuers.

Investment in Foreign Securities. The Fund may invest directly in the securities
of foreign issuers as well as in the form of sponsored and unsponsored 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 a United States 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. Issuers of unsponsored ADRs are
not required to disclose material information in the United States.

Foreign Currency Transactions. The Fund's foreign currency exchange transactions
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 also
enter into forward foreign currency exchange contracts to enhance return, to
hedge against fluctuations in currency exchange rates affecting a particular
transaction or portfolio position, or as a substitute for the purchase or sale
of a currency or assets denominated in that currency. 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 may elect to hedge less than all of
its foreign portfolio positions deemed appropriate by the Adviser and
Subadvisers.


                                       -3-
<PAGE>

If the Fund purchases a forward contract or sells a forward contract for
non-hedging purposes, its custodian will segregate cash or liquid securities, of
any type or maturity, in a separate account of the Fund in an amount equal to
the value of the Fund's total assets committed to the consummation of such
forward contract. The assets in the segregated account 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 be equal to the amount of the Fund's commitment with respect to
such contracts.

Hedging against a decline in the value of a currency does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of such securities decline. Such transactions also preclude the
opportunity for gain if the value of the hedged currency 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 transactions varies with
such factors as the currency involved, the length of the contract period and the
market conditions then prevailing. Since transactions in foreign currency are
usually conducted on a principal basis, no fees or commissions are involved.

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
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 


                                       -4-
<PAGE>

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.

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

The U.S. Government has from time to time in the past imposed restrictions,
through taxation and otherwise, on foreign investments by U.S. investors such as
the Fund. If such restrictions should be reinstituted, it might become necessary
for the Fund to invest all or substantially all of its assets in U.S.
securities. In such event, the Fund would review its investment objective and
investment policies to determine whether changes are appropriate.

The Fund's ability and decisions to purchase or sell portfolio securities may be
affected by laws or regulations relating to the convertibility and repatriation
of assets. Because the shares of the Fund are redeemable on a daily basis in
U.S. dollars, the Fund intends to manage its portfolio so as to give reasonable
assurance that it will be able to obtain U.S. dollars. Under present conditions,
it is not believed that these considerations will have any significant effect on
its portfolio strategy.

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


                                       -5-
<PAGE>

securities during the period in which the Fund seeks to enforce its rights
thereto, possible subnormal levels of income decline in value of the underlying
securities or lack of access to income during this period as well as the expense
of enforcing its rights.

Reverse Repurchase Agreements. The Fund may also enter into reverse repurchase
agreements which involve the sale of U.S. Government securities held in its
portfolio to a bank with an agreement that the Fund will buy back the securities
at a fixed future date at a fixed price plus an agreed amount of "interest"
which may be reflected in the repurchase price. Reverse repurchase agreements
are considered to be borrowings by the Fund. Reverse repurchase agreements
involve the risk that the market value of securities purchased by the Fund with
proceeds of the transaction may decline below the repurchase price of the
securities sold by the Fund which it is obligated to repurchase. The Fund will
also continue to be subject to the risk of a decline in the market value of the
securities sold under the agreements because it will reacquire those securities
upon effecting their repurchase. To minimize various risks associated with
reverse repurchase agreements, the Fund will establish and maintain with the
Fund's custodian a separate account consisting of liquid securities, of any type
or maturity, in an amount at least equal to the repurchase prices of these
securities (plus any accrued interest thereon) under such agreements. In
addition, the Fund will not borrow money or enter into reverse repurchase
agreements except from banks as a temporary measure for extraordinary emergency
purposes in amounts not to exceed 33 1/3% of the Fund's total assets (including
the amount borrowed) taken at market value. The Fund will not use leverage to
attempt to increase income. The Fund will not purchase securities while
outstanding borrowings exceed 5% of the Fund's total assets. The Fund will enter
into reverse repurchase agreements only with federally insured banks which are
approved in advance as being creditworthy by the Trustees. Under the procedures
established by the Trustees, the Adviser will monitor the creditworthiness of
the banks involved.

Restricted Securities. The Fund may purchase securities that are not registered
("restricted securities") under the Securities Act of 1933 ("1933 Act"),
including commercial paper issued in reliance on Section 4(2) of the 1933 Act
and securities offered and sold to "qualified institutional buyers" under Rule
144A under the 1933 Act. The Fund will not invest more than 15% of its net
assets in illiquid investments. If the Trustees determine, based upon a
continuing review of the trading markets for specific Section 4(2) paper or Rule
144A securities, that they are liquid, they 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 and monitoring the liquidity of
restricted securities. The Trustees, however, will retain sufficient oversight
and be ultimately responsible for the determinations. The Trustees will
carefully monitor the Fund's 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 foreign securities
exchanges or traded in the over-the-counter market. The Fund may write covered
put and call options and purchase put and call options to enhance total return,
as a substitute for the purchase or sale of securities or 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 the Fund obligates the 


                                       -6-
<PAGE>

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

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

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

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

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

The Fund's options transactions will be subject to limitations established by
each of the exchanges, boards of trade or other trading facilities on which such
options are traded. These limitations govern the maximum number of options in
each class which may be written or purchased by a single investor or group of
investors acting in concert, regardless of whether the options are written or
purchased on the same or different exchanges, boards of trade or other 


                                       -7-
<PAGE>

trading facilities or are held or written in one or more accounts or through one
or more brokers. Thus, the number of options which the Fund may write or
purchase may be affected by options written or purchased by other investment
advisory clients of the Adviser. An exchange, board of trade or other trading
facility may order the liquidation of positions found to be in excess of these
limits, and it may impose certain other sanctions.

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

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), in which event the secondary
market on that exchange (or in that class or series of options) would cease to
exist although outstanding options on that exchange that had been issued by the
Options Clearing Corporation as a result of trades on that exchange would
continue to be exercisable in accordance with their terms.

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

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

Futures Contracts and Options on Futures Contracts. To seek to increase total
return or hedge against changes in interest rates or securities prices, the Fund
may purchase and sell various kinds of futures contracts, and purchase and write
call and put options on these futures contracts. The Fund may also enter into
closing purchase and sale transactions with respect to any of these contracts
and options. The futures contracts may be based on various securities (such as
U.S. Government securities), securities indices and any other financial
instruments and indices. All futures contracts entered into by the Fund are
traded on U.S. 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 for an
agreed price during a designated 


                                       -8-
<PAGE>

month (or to deliver the final cash settlement price, in the case of a contract
relating to an index or otherwise not calling for physical delivery at the end
of trading in the contract).

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

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

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

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


                                       -9-
<PAGE>

position if prices move in a favorable direction but limits its risk of loss in
the event of an unfavorable price movement to the loss of the premium and
transaction costs.

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

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

Other Considerations. The Fund will engage in futures and related options
transactions either for bona fide hedging purposes or to seek to increase total
return as permitted by the CFTC. To the extent that the Fund is using futures
and related options for hedging purposes, futures contracts will be sold to
protect against a decline in the price of securities that the Fund owns or
futures contracts will be purchased to protect the Fund against an increase in
the price of securities it intends to purchase. The Fund will determine that the
price fluctuations in the futures contracts and options on futures used for
hedging purposes are substantially related to price fluctuations in securities
held by the Fund or securities or instruments which it expects to purchase. As
evidence of its hedging intent, the Fund expects that on 75% or more of the
occasions on which it takes a long futures or option position (involving the
purchase of futures contracts), the Fund will have purchased, or will be in the
process of purchasing, equivalent amounts of related securities (or assets
denominated in the related currency) in the cash market at the time when the
futures or option position is closed out. However, in particular cases, when it
is economically advantageous for the Fund to do so, a long futures position may
be terminated or an option may expire without the corresponding purchase of
securities or other assets.

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


                                      -10-
<PAGE>

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

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

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

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

Short Sales. The Fund may engage in short sales against the box. In a short sale
against the box, the Fund agrees to sell at a future date a security that it
either contemporaneously owns or has the right to acquire at no extra cost. If
the price of the security has declined at the time the Fund is required to
deliver the security, the Fund will benefit from the difference in the price. If
the price of the security has increased, the Fund will be required to pay the
difference.

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


                                      -11-
<PAGE>

When the Fund engages in forward commitment and when-issued transactions, it
relies on the seller to consummate the transaction. The failure of the issuer or
seller to consummate the transaction may result in the Fund's losing the
opportunity to obtain a price and yield considered to be advantageous. The
purchase of securities on a when-issued or forward commitment basis also
involves a risk of loss if the value of the security to be purchased declines
prior to the settlement date.

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

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

INVESTMENT RESTRICTIONS

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

The Fund may not:

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

     (2) Borrow money, except from banks as a temporary measure for
     extraordinary emergency purposes in amounts not to exceed 33 1/3% of the
     Fund's total assets (including the amount borrowed) taken at market value.
     The Fund will not use leverage to attempt to increase income. The Fund will
     not purchase securities while outstanding borrowings exceed 5% of the
     Fund's total assets.


                                      -12-
<PAGE>

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

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

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

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

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

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

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

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

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

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

The Fund may not:

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


                                      -13-
<PAGE>

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

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

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

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

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

Nothing in the foregoing investment restrictions shall be deemed to prohibit the
Fund from purchasing the securities of any issuer pursuant to the exercise of
subscription rights distributed to the Fund by the issuer, except that no such
purchase may be made if as a result, the Fund will no longer be a diversified
investment company as defined in the Investment Company Act or will fail to meet
the diversification requirements for a regulated investment company under the
Internal Revenue Code of 1986, as amended. Japanese corporations frequently
issue additional capital stock by means of subscription rights offerings to
existing shareholders at a price substantially below the market prices of the
shares. The failure to exercise such rights would result in the Fund's interest
in the issuing company being diluted. The market for such rights is not well
developed in all cases and, accordingly, the Fund may not always realize full
value on the sale of rights. Therefore, the exception applies in cases where the
limits set forth in the investment restrictions in the Prospectus would
otherwise be exceeded as a result of fluctuations in the market value of the
Fund's portfolio securities with the result that the Fund would be forced either
to sell securities at a time when it might not otherwise have done so, or to
forego exercising the rights.

THOSE RESPONSIBLE FOR MANAGEMENT

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

INVESTMENT ADVISORY AND OTHER SERVICES

   
The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts 02199-7603,
was organized in 1968 and has more than $26 billion in assets under management
in its capacity as investment adviser to the Fund and the other mutual funds and
publicly traded investment companies in the John Hancock group of funds having a
combined total of over 1,400,000 shareholders. The Adviser is an affiliate of
the Life Company, one of the most recognized and respected financial
institutions in the nation. With total assets under management of more than $100
billion, the Life Company is one of the ten largest life insurance companies in
the United States, and carries high ratings from Standard & Poor's and A.M.
Best's. Founded in 1862, the Life Company has been serving clients for over 130
years.
    

JHAI, with offices located at 34 Dover Street, London, England W1X 3RA, is a
wholly owned subsidiary of the Adviser and was formed in 1987 to provide
international investment research and advisory services to U.S. institutional
clients.

IAAL is a Hong-Kong based investment adviser located at One Exchange Square,
Suite 2606-2608, Hong Kong.

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

The Adviser has entered into a sub-investment management contract ("Sub-Advisory
Agreement") with each Subadviser under which the Subadvisers, subject to the
review of the Trustees and the overall supervision of the Adviser, are
responsible for providing the Fund with advice with respect to that portion of
the assets invested in countries other than the U.S. and Canada.


                                      -23-
<PAGE>

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

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

Net Asset Value                         Annual Rate
- ---------------                         -----------
First $200,000,000                         0.80%
Amount over $200,000,000                   0.70%

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, a Subadviser or any of their respective
affiliates provides investment advice. Because of different investment
objectives or other factors, a particular security may be bought for one or more
funds or clients when one or more other funds or clients are selling the same
security. If opportunities for purchase or sale of securities by the Adviser or
the Subadvisers for the Fund or for other funds or clients for which the Adviser
or a Subadviser 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, a Subadviser or its affiliate may increase the demand for securities
being purchased or the supply of securities being sold, there may be an adverse
effect on price.

   
The Advisory Agreement fee paid by the Fund is higher than the fee paid by most
mutual funds but is comparable to the fee paid by similar funds which invest
primarily in international securities. During the years ended August 31, 1996
and 1995, the Fund paid the Adviser fees in the amount of $542,565 and $430,725,
respectively. For the period from September 1, 1996 to October 31, 1996, and for
the fiscal year ended October 31, 1997, the Fund paid the Adviser fees in the
amount of $99,055 and $494,141, respectively. In 1996, the Trustees changed the
fiscal year of the Fund to October 31, 1996.
    

The Adviser pays JHAI a quarterly management fee at the annual rate as follows:


                                      -24-
<PAGE>

Net Asset Value                          Annual Rate
- ---------------                          -----------
First $200,000,000                          0.50%
Amount over $200,000,000                    0.4375%

The Fund is not responsible for paying JHAI's fee. As of September 1, 1994, JHAI
limited its fee to 0.05% of average daily net assets.

The Adviser pays IAAL a fee at the annual rate equal to (a) .30% of the first
$100 million of the Fund's average daily net assets managed by IAAL plus (b) the
following additional amount, based on a percentage of the gross management fee
received by the Adviser pursuant to the Advisory Agreement with respect to the
Fund's average daily net assets in excess of $100 million which are managed by
IAAL:

Net Assets                                      Percentage of Gross
Managed by IAAL                                 Management Fee
- ---------------                                 --------------

More than $100 million up to $250 million              40%
More than $250 million                                 50%

The Fund is not responsible for paying IAAL's fee.

   
Pursuant to their respective Advisory Agreements, the Adviser and Subadvisers
are 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 the Agreements
relate, except a loss resulting from willful misfeasance, bad faith or gross
negligence on the part of the Adviser or Subadvisers in the performance of their
duties or from reckless disregard by them of their obligations and duties under
the applicable Agreement.

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

The continuation of the Advisory Agreement, the Sub-Advisory Agreement, and the
Distribution Agreement (discussed below) was approved by all of the Trustees.
The Advisory Agreement, Sub-Advisory Agreement and the Distribution Agreement,
will continue in effect from year to year, provided that its continuance is
approved annually both (i) by the holders of a majority of the outstanding
voting securities of the Trust or by the Trustees, and (ii) by a majority of the
Trustees who are not parties to the Agreement "interested persons" of any such
parties. Each agreement may be terminated on 60 days' written notice by either
party or by vote of a majority of the outstanding voting securities of the Fund
and will terminate automatically if assigned.

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 period from September 1, 1996 to October 31, 1996,
the Fund paid the Adviser $2,322 for services under this 
    


                                      -25-
<PAGE>

   
agreement. For the fiscal year ended October 31, 1997, the Fund paid the Adviser
$11,378 for services under this Agreement.
    

In order to avoid conflicts with portfolio trades for the Fund, the Adviser, the
Subadvisers and the Fund have adopted extensive restrictions on personal
securities trading by personnel of the Adviser, the Subadvisers and their
respective affiliates. In the case of the Adviser, 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. A Subadviser's restrictions may differ
where appropriate, as long as they maintain the same intent. These restrictions
are a continuation of the basic principle that the interests of the Fund and its
shareholders come first.

DISTRIBUTION CONTRACTS

   
The Fund has a Distribution Agreement with John Hancock Funds. Under the
agreement, John Hancock Funds is obligated to use its best efforts to sell
shares of each class 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. In the case of Class B shares, the broker receives
compensation immediately but John Hancock Funds is compensated on a deferred
basis. John Hancock Funds may pay extra compensation to financial services firms
selling large amounts of fund shares. This compensation would be calculated as a
percentage of fund shares sold by the firm.

Total underwriting commissions for sales of the Fund's Class A shares for the
fiscal periods ended October 31, 1997, September 1, 1996 to October 31, 1996,
August 31, 1996 and August 31, 1995 were $91,016, $23,075, $354,754 and
$216,466, respectively, and $13,196, $3,415, $50,356 and $20,415, respectively,
were retained by John Hancock Funds in 1997, 1996 and 1995, respectively. The
remainder of the underwriting commissions were reallowed to dealers.

The Fund's Trustees adopted Distribution Plans with respect to Class A and Class
B shares (the "Plans") pursuant to Rule 12b-1 under the Investment Company Act
of 1940. Under the Plans, the Fund will pay distribution and service fees at an
aggregate annual rate of up to 0.30% and 1.00%, respectively, of the Fund's
average daily net assets attributable to shares of that class. However, the
service fee will not exceed 0.25% of the Fund's average daily net assets
attributable to each class of shares. The distribution fees will be used to
reimburse 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 be used to compensate Selling Brokers and others for providing personal and
account maintenance services to shareholders. In the event that John Hancock
Funds is not fully reimbursed for payments or expenses they incur under the
Class A Plan, these expenses will not be carried beyond twelve months from the
date they were incurred. Unreimbursed expenses under the Class B Plan will be
carried forward together with interest on the balance of these unreimbursed
expenses. The Fund does not treat 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 October 31, 1997, an aggregate of
$1,045,211 of distribution expenses or 3.85% of the average net assets of 
    


                                      -26-
<PAGE>

the Class B shares of the Fund, was not reimbursed or recovered by John Hancock
Funds through the receipt of deferred sales charges or Rule 12b-1 fees in prior
periods.

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

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

The Plans provide that they will continue in effect only so long as their
continuance is approved at least annually by a majority of both the Trustees and
Independent Trustees. The Plans provide that they may be terminated without
penalty, (a) by vote of a majority of the Independent Trustees, (b) by a vote of
a majority of the Fund's outstanding shares of the applicable class 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 that 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 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.

   
For the fiscal year ended October 31, 1997, the Fund paid John Hancock Funds the
following amounts of expenses in connection with their services for the Fund:

                                  Expense Items

NET ASSET VALUE

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

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 last
available bid price.

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

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

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

INITIAL SALES CHARGE ON CLASS A SHARES

Shares of the Fund are offered at a price equal to their net asset value plus a
sales charge which, at the option of the purchaser, may be imposed either at the
time of purchase (the "initial sales charge alternative") or on a contingent
deferred basis (the "deferred sales charge alternative"). Share certificates
will not be issued unless requested by the shareholder in writing, and then they
will only be issued for full shares. The Trustees reserve the right to change or
waive the 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 shares of Class A shares of the
Fund are described in the Prospectus. Methods of obtaining a reduced sales
charge 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 cumulate current purchases


                                      -28-
<PAGE>

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.*

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 you Merill 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:


                                      -29-
<PAGE>

      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 of all John
Hancock funds which carry a sales charge already held by such person. Class A
shares of John Hancock money market funds will only be eligible for the
accumulation privilege if the investor has previously paid a sales charge on the
amount of those shares.

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

Letter of Intention. Reduced sales charges are also applicable to investments
made pursuant to a Letter of Intention (the "LOI"), which should be read
carefully prior to its execution by an investor. The Fund offers two options
regarding the specified period for making investments under the LOI. All
investors have the option of making their investments over a specified period of
thirteen (13) months. Investors who are using the Fund as a funding medium for a
retirement plan, however, may opt to make the necessary investments called for
by the LOI over a forty-eight (48) month period. These retirement plans include
IRAs, SEP, SARSEP, 401(k), 403(b) (including TSAs), SIMPLE IRA, SIMPLE 401(k),
Money Purchase Pension, Profit Sharing and Section 457 plans. Such an investment
(including accumulations and combinations) must aggregate $50,000 or more
invested during the specified period from the date of the LOI or from a date
within ninety (90) days prior thereto, upon written request to Signature
Services. The sales charge applicable to all amounts invested under the LOI is
computed as if the aggregate amount intended to be invested had been invested
immediately. If such aggregate amount is not 
    


                                      -30-
<PAGE>

actually invested, the difference in the sales charge actually paid and the
sales charge payable had the LOI not been in effect is due from the investor.
However, for the purchases actually made within the specified period (either 13
or 48 months) the sales charge applicable will not be higher than that which
would have applied (including accumulations and combinations) had the LOI been
for the amount actually invested.

The LOI authorizes Signature Services to hold in escrow sufficient Class A
shares (approximately 5% of the aggregate) to make up any difference in sales
charges on the amount intended to be invested and the amount actually invested,
until such investment is completed within the specified period, at which time
the 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 the sales charge as may be due. By
signing the LOI, the investor authorizes Signature Services to act as his or her
attorney-in-fact to redeem any escrowed Class A shares and adjust the sales
charge, if necessary. A LOI does not constitute a binding commitment by an
investor to purchase or by the Fund to sell any additional Class A shares and
may be terminated at any time.

DEFERRED SALES CHARGE ON CLASS B SHARES

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

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

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

The amount of the CDSC, if any, will vary depending on the number of years from
the time of payment for the purchase of Class B shares until the time of
redemption of such shares. Solely for purposes of determining the number 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.
    

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.


                                      -31-
<PAGE>

   
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:

      o Proceeds of 50 shares redeemed at $12 per shares (50 x 12)    $600.00
      o*Minus Appreciation ($12 - $10) x 100 shares                   (200.00)
      o Minus proceeds of 10 shares not subject to CDSC (dividend
        reinvestment)                                                 (120.00) 
                                                                      -------  
      o Amount subject to CDSC                                        $280.00

      *The appreciation is based on all 100 shares in the lot not just the
      shares being redeemed.

Proceeds from the CDSC are paid to John Hancock Funds and are used in whole or
in part by John Hancock Funds to defray its expenses related to providing
distribution-related services to the Fund in connection with the sale of the
Class B 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.

*    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.

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

SPECIAL REDEMPTIONS

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

ADDITIONAL SERVICES AND PROGRAMS

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

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

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

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

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

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

   
Systematic Withdrawal Plan. The Fund permits the establishment of a Systematic
Withdrawal Plan. Payments under this plan represent proceeds arising from the
redemption of Fund shares which 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 
    


                                      -35-
<PAGE>

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 shares at the same time a Systematic Withdrawal Plan is in effect. The
Fund reserves the right to modify or discontinue the Systematic Withdrawal Plan
of any shareholder on 30 days' prior written notice to such shareholder, or to
discontinue the availability of such plan in the future. The shareholder may
terminate the plan at any time by giving proper notice to Signature Services.

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

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

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

The program may be discontinued by the shareholder either by calling Signature
Services or upon written notice to Signature Services which is received at least
five (5) business days prior to the 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 in that fund.
The proceeds from the redemption of Class A shares may be reinvested at net
asset value without paying a sales charge in Class A shares of the Fund or in
Class A shares of any John Hancock fund. If a CDSC was paid upon a redemption, a
shareholder may reinvest the proceeds from this redemption at net asset value in
additional shares of the class from which the redemption was made. The
shareholder's account will be credited with the amount of any CDSC charged upon
the prior redemption and the new shares will continue to be subject to the CDSC.
The holding period of the shares acquired through reinvestment will, for
purposes of computing the CDSC payable upon a subsequent redemption, include the
holding period of the redeemed shares.
    

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

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

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

Retirement plans participating in Merrill Lynch's servicing programs:

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

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

DESCRIPTION OF THE FUND'S SHARES

The Trustees of the Trust are responsible for the management and supervision of
the Fund. The Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of the Fund, without
par value. Under the Declaration of Trust, the Trustees have the authority to
create and classify shares of beneficial interest in separate series, without
further action by shareholders. As of the date of this Statement of Additional
Information, the Trustees have authorized shares of the Fund and two 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 the Fund,
or any new series of the Trust, into one or more classes. As of the date of this
Statement of Additional Information, the Trustees have authorized the issuance
of two classes of shares of the Fund, designated as Class A and Class B.

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

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

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

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


                                      -37-
<PAGE>

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

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

The Fund reserves the right to reject any application which conflicts with the
Fund's internal policies or the policies of any regulatory authority. John
Hancock Funds does not accept credit card checks. Use of information provided on
the account application may be used by the Fund to verify the accuracy of the
information or for background or financial history purposes. A joint account
will be administered as a joint tenancy with right of survivorship, unless the
joint owners notify Signature Services of a different intent. A shareholder's
account is governed by the laws of The Commonwealth of Massachusetts.

TAX STATUS

   
Each series of the Trust, including the Fund, is treated as a separate entity
for tax purposes. The Fund has qualified as a "regulated investment company"
under Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code")
and intends to continue to so qualify for each taxable year. As such and by
complying with the applicable provisions of the Code regarding the sources of
its income, the timing of its distributions, and the diversification of its
assets, the Fund will not be subject to Federal income tax on its taxable income
(including net realized capital gains) which is distributed to shareholders in
accordance with the timing requirements of the Code.
    

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

   
Distributions from the Fund's current or accumulated earnings and profits
("E&P") will be taxable under the Code for investors who are subject to tax. If
these distributions are paid from the Fund's "investment company taxable
income," they will be taxable as ordinary income; and if they are paid from the
Fund's "net capital gain," they will be taxable as capital gain. (Net capital
gain is the excess (if any) of net long-term capital gain over net short-term
capital loss, and investment company taxable income is all taxable income and
capital gains, other than those gains and losses included in computing net
capital gain, after reduction by deductible expenses.) As a result of federal
tax legislation enacted on August 5, 1997 (the "Act"), gain recognized after May
6, 1997 from the sale of a capital asset is taxable to individual (noncorporate)
investors at different maximum federal income tax rates, depending generally
upon the tax holding period for the asset, the federal income tax bracket of the
taxpayer, and the dates the asset was acquired and/or sold. The Treasury
Department has issued guidance under the Act that enables the Fund to pass
through to its shareholders the benefits of the capital gains rates enacted in
the Act. Shareholders should consult their own tax advisers on the correct
application of these new rules 
    


                                      -38-
<PAGE>

   
in their particular circumstances. Some distributions may be paid in January but
may be taxable to shareholders as if they had been received on December 31 of
the previous year. The tax treatment described above will apply without regard
to whether distributions are received in cash or reinvested in additional shares
of the Fund.
    

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

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

If the Fund invests in stock (including an option to acquire stock such as is
inherent in a convertible bond) of certain foreign corporations that receive at
least 75% of their annual gross income from passive sources (such as interest,
dividends, certain rents and 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 these
passive foreign investment 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. An election may be
available to ameliorate these adverse tax consequences, but could require the
Fund to recognize taxable income or gain without the concurrent receipt of cash.
These investments could also result in the treatment of associated capital gains
as ordinary income. The Fund may limit and/or manage its investments in passive
foreign investment companies or make an available election to minimize its tax
liability or maximize its return from these investments.

The amount of the Fund's net realized capital gains, if any, in any given year
will vary depending upon the current investment strategy of the Adviser and
Subadvisers and whether the Adviser and the Subadvisers believes it to be in the
best interest of the Fund to dispose of portfolio securities and/or engage in
options, futures or forward transactions that will generate capital gains. At
the time of an investor's purchase of Fund shares, a portion of the purchase
price is often attributable to realized or unrealized appreciation in the Fund's
portfolio or undistributed taxable income of the Fund. Consequently, subsequent
distributions on those shares from such appreciation or income may be taxable to
such investor even if the net asset value of the investor's shares is, as a
result of the 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.
    


                                      -39-
<PAGE>

   
Upon a redemption or other disposition of shares of the Fund (including by
exercise of the exchange privilege) in a transaction that is treated as a sale
for tax purposes, a shareholder may realize a taxable gain or loss depending
upon the amount of the proceeds and the investor's basis in his shares. Such
gain or loss will be treated as capital gain or loss if the shares are capital
assets in the shareholder's hands. A sales charge paid in purchasing Class A
shares of the Fund cannot be taken into account for purposes of determining gain
or loss on the redemption or exchange of such shares within 90 days after their
purchase to the extent Class A shares of the Fund or another John Hancock fund
are subsequently acquired without payment of a sales charge pursuant to the
reinvestment or exchange privilege. This disregarded charge will result in an
increase in the shareholder's tax basis in the shares subsequently acquired.
Also, any loss realized on a redemption or exchange may be disallowed to the
extent the shares disposed of are replaced with other shares of the Fund within
a period of 61 days beginning 30 days before and ending 30 days after the shares
are disposed of, such as pursuant to automatic dividend reinvestments. In such a
case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss. Any loss realized upon the redemption of shares with a tax
holding period of six months or less will be treated as a long-term capital loss
to the extent of any amounts treated as distributions of long- term capital gain
with respect to such shares. Shareholders should consult their own tax advisers
regarding their particular circumstances to determine whether a disposition of
Fund shares is properly treated as a sale for tax purposes, as is assumed in the
foregoing discussion. Also, future Treasury Department guidance issued to
implement the Act may contain additional rules for determining the tax treatment
of sales of Fund shares held for various periods, including the treatment of
losses on the sales of shares held for six months or less that are
recharacterized as long-term capital losses, as described above.

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

For Federal income tax purposes, the Fund is permitted to carry forward a net
realized capital loss in any year to offset net capital gains, if any, during
the eight years following the year of the loss. To the extent subsequent net
capital gains are offset by such losses, they would not result in Federal income
tax liability to the Fund and, as noted above, would not be distributed as such
to shareholders. The Fund has $369,905 of capital loss carryforwards available
to the extent provided by regulations, to offset future net realized capital
gains. The whole amount of the carryforward expires on October 31, 2005.

For purposes of the dividends-received deduction available to corporations,
dividends received by the Fund, if any, from U.S. domestic corporations in
respect of any share of stock held by the Fund, for U.S. Federal income tax
purposes, for at least 46 days (91 days in the case of certain 
    


                                      -40-
<PAGE>

   
preferred stock) during a prescribed period extending before and after each such
dividend and distributed and properly designated by the Fund may be treated as
qualifying dividends. Corporate shareholders must meet the holding period
requirements stated above with respect to their shares of the Fund for each
dividend in order to qualify for the deduction and, if they have any debt that
is deemed under the Code directly attributable to such shares, may be denied a
portion of the dividends received deduction. The entire qualifying dividend,
including the otherwise-deductible amount, will be included in determining
alternative minimum tax liability, if any. Additionally, any corporate
shareholder should consult its tax adviser regarding the possibility that its
tax basis in its shares may be reduced, for Federal income tax purposes, by
reason of "extraordinary dividends" received with respect to the shares and, to
the extent such basis would be reduced below zero, that current recognition of
income would be required.
    

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

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

   
The 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 or constructive sale rules applicable to certain options, futures,
forwards, short sales or other transactions may also require the Fund to
recognize income or gain without a concurrent receipt of cash. Additionally,
some countries restrict repatriation which may make it difficult or impossible
for the Fund to obtain cash corresponding to its earnings or assets in those
countries. However, the Fund must distribute to shareholders for each taxable
year substantially all of its net income and net capital gains, including such
income or gain, to qualify as a regulated investment company and avoid liability
for any federal income 
    


                                      -41-
<PAGE>

or excise tax. Therefore, the Fund may have to dispose of its portfolio
securities under disadvantageous circumstances to generate cash, or borrow cash,
to satisfy these distribution requirements.

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

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

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 options, futures, foreign currency
positions, and foreign currency forward contracts.

   
Certain options, futures and forward foreign currency contracts undertaken by
the Fund may cause the Fund to recognize gains or losses from marking to market
even though its positions have not been sold or terminated and affect the
character as long-term or short-term (or, in the case of foreign currency
contracts, as ordinary income or loss) and timing of some capital gains and
losses realized by the Fund. Additionally, the Fund may be required to recognize
gain, but not loss, if an option, short sale or other transaction is treated as
a constructive sale of an appreciated financial position in the Fund's
portfolio. Also, certain of the Fund's losses on its transactions involving
options, futures or forward contracts and/or offsetting or successor portfolio
positions may be deferred rather than being taken into account currently in
calculating the Fund's taxable income or gains. Certain of such transactions may
also cause the Fund to dispose of investments sooner than would otherwise have
occurred. These transactions may therefore affect the amount, timing and
character of the Fund's distributions to shareholders. The Fund will take into
account the special tax rules (including consideration of available elections)
    


                                      -42-

applicable to options, futures and forward contracts in order to seek to
minimize any potential adverse tax consequences.

The foregoing discussion relates solely to U.S. Federal income tax law as
applicable to U.S. persons (i.e., U.S. citizens or residents and U.S. domestic
corporations, partnerships, trusts or estates) subject to tax under such law.
The discussion does not address special tax rules applicable to certain classes
of investors, such as tax-exempt entities, insurance companies, and financial
institutions. Dividends, capital gain distributions, and ownership of or gains
realized on the redemption (including an exchange) of Fund shares may also be
subject to state and local taxes. Shareholders should consult their own tax
advisers as to the Federal, state or local tax consequences of ownership of
shares of, and receipt of distribution 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 non-resident alien withholding tax at the rate of
30% (or a lower rate under an applicable tax treaty) on amounts treated as
ordinary dividends from the Fund and, unless an effective IRS Form W-8 or
authorized substitute for Form W-8 is on file, to 31% backup withholding on
certain other payments from the Fund. Non-U.S. investors should consult their
tax advisers regarding such treatment and the application of foreign taxes to an
investment in the Fund.

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

Hong Kong Taxes

Taxation of the Fund. The Fund will be subject to Hong Kong profits tax at the
current rate of 16.5% if (i) it carries on business in Hong Kong and (ii) its
profits are derived from a Hong Kong source. Dividends and capital gains are
exempt from profits tax in any event, as are profits from trading in securities
listed on exchanges outside Hong Kong. Profits from trading in securities listed
on a Hong Kong exchange may in certain cases be subject to profits tax.

Taxation of Shareholders. There is no tax in Hong Kong on capital gains arising
from the sale by an investor of shares of the Fund. However, in the case of
certain investors (principally share traders, financial institutions and certain
companies carrying on business in Hong Kong), such gains may be considered to be
part of the investor's normal business profits and in such circumstances will be
subject to Hong Kong profits tax at the current rate of 16.5% for corporations
and 15% for individuals. Dividends which the Fund pays to its shareholders are
not taxable in Hong Kong (whether through withholding or otherwise) under
current legislation and practice. No Hong Kong stamp duty will be payable in
respect of transactions in the Fund's shares provided that the register of
shareholders is maintained outside of Hong Kong.

CALCULATION OF PERFORMANCE

   
The average annual total return on Class A shares of the Fund for the 1 year, 5
year and 10 year periods ended October 31, 1997 was (23.08)%, 4.94% and 4.94%,
respectively. The average annual total return on Class B shares of the Fund for
the one year period ended October 31, 1997 and since commencement of operations
on March 7, 1994 was (23.66)% and (7.16)%, respectively.
    


                                      -43-
<PAGE>

Total return is computed by finding the average annual compounded rate of return
over the 1 year, 5 year and life-of-fund periods that would equate the initial
amount invested to the ending redeemable value according to the following
formula:

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

Where:

   
P =   a hypothetical initial investment of $1,000. 
T =   average annual total return.
n =   number of years.
ERV = ending redeemable value of a hypothetical $1,000 investment made at the
      beginning of the 1 year, 5 year and 10 year periods.

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

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

From time to time, in reports and promotional literature, the Fund's total
return will be compared to indices of mutual funds such as Lipper Analytical
Services, Inc.'s "Lipper - Mutual Fund Performance Analysis," a monthly
publication which tracks net assets and total return on 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, BARRON'S, etc. 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 


                                      -44-
<PAGE>

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, Subadvisers, and officers and Trustees
who are interested persons of the Trust. Orders for purchases and sales of
securities are placed in a manner which, in the opinion of the officers 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 maker 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
foreign transactions are generally higher than the negotiated commission rates
available in the U.S. There is generally less government supervision and
regulation of foreign stock exchanges and broker-dealers than in the U.S.

The Fund's primary policy is to execute all purchases and sales of portfolio
instruments at the most favorable prices consistent with best execution,
considering all of the costs of the transaction including brokerage commissions.
This policy governs the selection of brokers and dealers and the market in which
a transaction is executed. Consistent with the foregoing primary policy, the
Rules of Fair Practice of the National Association of Securities Dealers, Inc.
and such other policies as the Trustees may determine, the Adviser or a
Subadviser 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 and the
Subadvisers 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 and the Subadvisers.
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 or Subadvisers, and, conversely, brokerage commissions
and spreads paid by other advisory clients of the Adviser and Subadvisers may
result in research information and statistical assistance beneficial to the
Fund. The Fund will make no commitment to allocate portfolio transactions upon
any prescribed basis. While the Adviser's, together with the Subadvisers'
officers, will be primarily responsible for the allocation of the Fund's
brokerage business, the policies and practices of the Adviser and Subadvisers in
this regard must be consistent with the foregoing and at all times be subject to
review by the Trustees. For the fiscal years ended August 31, 1995 and
    


                                      -45-
<PAGE>

   
1996, the Fund paid negotiated brokerage commissions of $246,610 and $530,822,
respectively. For the period from September 1, 1996 to October 31, 1996, and
October 31, 1997, the Fund paid negotiated commissions of $127,834 and $629,393,
respectively.

As permitted by Section 28(e) of the Securities Exchange Act of 1934, the Fund
may pay to a broker-dealer which provides brokerage and research services to the
Fund an amount of disclosed commission in excess of the commission which another
broker- dealer 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 October 31,
1997, the Fund did not pay commissions as compensation to any brokers for
research services such as industry, economic and company reviews and evaluations
of securities.
    

The Adviser's indirect parent, the Life Company, is the indirect sole
shareholder of John Hancock Distributors, Inc., a broker-dealer ("Distributors"
or "Affiliated Broker"). Also included as an Affiliated Broker is W.I. Carr
Group, a British brokerage firm specializing in Asian securities, which is
directly owned by Banque Indosuez, one of the indirect parents of IAAL. 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. For the fiscal year ended October 31, 1997, the Fund
paid no brokerage commissions to 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
with comparable transactions involving similar securities being purchased or
sold. A transaction would not be placed with an Affiliated Broker if the Fund
would have to pay a commission rate less favorable than the Affiliated Broker's
contemporaneous charges for comparable transactions for its other most favored,
but unaffiliated, customers except for accounts for which the Affiliated Broker
acts as clearing broker for another 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 and
the Subadvisers, which are affiliated with the Affiliated Broker, have, as
investment advisers 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 Broker as a
basis for negotiating commissions at a rate higher than that determined in
accordance with the above criteria.

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

APPENDIX

RATINGS

The Fund's investments in debt securities must be in obligations rated Baa or
better by Moody's Signature Services, Inc. ("Moody's") or BBB or better by
Standard & Poor's Ratings Group ("Standard & Poor's") or be of comparable
quality in the judgment of the Adviser or a Subadviser if no rating has been
assigned by either service.

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

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

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

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

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

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

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

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

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

     "BBB. Bonds rated BBB are regarded as having an adequate capacity to pay
principal and interest. Whereas they normally exhibit adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay principal and interest for bonds in
this category than for bonds in the A category.

Item 27.  Indemnification
</TABLE>

     (a) Under Registrant's  Declaration of Trust.  Sections 4.1, 4.2 and 4.3 of
Article VI of the Registrant's Amended and Restated Declaration of Trust provide
for  indemnification  of the  Registrant's  Trustees and Officers  under certain
circumstances.  A copy of the Registrant's  Amended and Restated  Declaration of
Trust is attached as Exhibit 1 to this  Post-Effective  Amendment  No. 18 to the
Registration Statement of the Registrant.

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


                                      C-1

<PAGE>

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

     Article IX of the respective  By-Laws of John Hancock Funds and the Adviser
provide as follows:

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

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

Insofar as indemnification for liabilities under the Securities Act of 1933 (the
"Act")  may be  permitted  to  Trustees,  officers  and  controlling  persons of
Registrant  pursuant  to the  Registrant's  Amended  and  Restated  Articles  of
Incorporation,  Article  10.1  of the  Registrant's  By-Laws,  The  underwriting
Agreement, the By-Laws of Distributors, the Adviser, or the Insurance Company or
otherwise, Registrant has been advised that in the opinion of the Securities and
Exchange  Commission such  indemnification is against policy as expressed in the
Act  and  is,  therefore,   unenforceable.   In  the  event  that  a  claim  for


                                      C-2

<PAGE>

indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by such Trustee,  officer or controlling  person in connection with the
securities  being  registered,  Registrant  will,  unless in the  opinion of its
counsel the matter has been settled by controlling precedent,  submit to a court
of  appropriate  jurisdiction  the  question  whether  indemnification  by it is
against  public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

          of 1940, as amended.

     The  Declaration  of Trust is hereby  amended  to the extent  necessary  to
reflect the establishment of such additional  series of Shares,  effective March
