Overview

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

FUND INFORMATION KEY

Concise fund-by-fund descriptions begin on the next page. Each description
provides the following information:

[Clip Art] Goal and strategy The fund's particular investment goals and the
strategies it intends to use in pursuing those goals.

[Clip Art] Portfolio securities The primary types of securities in which the
fund invests. Secondary investments are described in "More about risk" at the
end of the prospectus.

[Clip Art] Risk factors The major risk factors associated with the fund.

[Clip Art] Portfolio management The individual or group (including subadvisers,
if any) designated by the investment adviser to handle the fund's day-to-day
management.

[Clip Art] Expenses The overall costs borne by an investor in the fund,
including sales charges and annual expenses.

[Clip Art] Financial highlights A table showing the fund's financial performance
for up to ten years, by share class. A bar chart showing total return allows you
to compare the fund's historical risk level to those of other funds.

GOAL OF THE GROWTH FUNDS

John Hancock growth funds seek long-term growth by investing primarily in common
stocks. Each fund has its own strategy and its own risk/reward profile. Because
you could lose money by investing in these funds, be sure to read all risk
disclosure carefully before investing.

WHO MAY WANT TO INVEST

These funds may be appropriate for investors who:

o  have longer time horizons

o  are willing to accept higher short-term risk along with higher potential
   long-term returns

o  want to diversify their portfolios

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

o  are investing for retirement or other goals that are many years in the future

Growth funds may NOT be appropriate if you:

o  are investing with a shorter time horizon in mind

o  are uncomfortable with an investment that will go up and down in value

THE MANAGEMENT FIRM

All John Hancock growth 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.

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

GOAL AND STRATEGY

[Clip Art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in emerging companies (market capitalization of less than $1
billion). Under normal circumstances, the fund invests at least 80% of assets in
a diversified portfolio of these companies. The fund looks for companies that
show rapid growth but are not yet widely recognized. The fund also may invest in
established companies that, because of new management, products or
opportunities, offer the possibility of accelerating earnings. The fund does not
invest for income.

PORTFOLIO SECURITIES

[Clip Art] The fund invests primarily in the common stocks of U.S. and foreign
emerging growth companies, although it may invest up to 20% of assets in other
types of companies. The fund may also invest in warrants, preferred stocks and
investment-grade convertible debt securities. 

For liquidity and flexibility, the fund may place up to 20% of assets in cash or
in investment-grade short-term securities. In abnormal market conditions, it may
invest more assets in these securities as a defensive tactic. The fund also may
invest in certain higher-risk 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. Stocks of emerging growth companies carry
higher risks than stocks of larger companies. This is because emerging growth
companies:

o  may be in the early stages of development
o  may be dependent on a small number of products or services
o  may lack substantial capital reserves
o  do not have proven track records

   
In addition, stocks of emerging companies are often traded in low volumes, which
can increase market and liquidity risks. Before you invest, please read "More
about risk" starting on page 27.

Financial Industries Fund

REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST II
                                TICKER SYMBOL    CLASS A: FIDAX   CLASS B: FIDBX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip Art] The fund seeks capital appreciation. To pursue this goal, the fund
invests in U.S. and foreign financial services companies. These include banks,
thrifts, finance companies, brokerage and advisory firms, real estate-related
firms and insurance companies.

Under normal circumstances, the fund invests at least 65% of assets in these
companies.

PORTFOLIO SECURITIES

[Clip Art] The fund invests primarily in the common stocks of U.S. and foreign
companies. It may also invest in warrants, preferred stocks and debt securities.

The fund may invest up to 5% of net assets in junk bonds.

For liquidity and flexibility, the fund may place up to 15% of net assets in
cash or in investment-grade short-term securities. In abnormal market
conditions, it may invest up to 80% in these securities as a defensive tactic.
The fund may also 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 in a single
sector, its performance is largely dependent on the sector's performance, which
may differ from that of the overall stock market. Falling interest rates or
deteriorating economic conditions can adversely affect the performance of
financial services companies' stocks, while rising interest rates will cause a
decline in the value of any debt securities the fund holds. Before you invest,
please read "More about risk" starting on page 27.
    

PORTFOLIO MANAGEMENT

[Clip Art] James K. Schmidt, CFA, leads the fund's management team. Mr. Schmidt,
executive vice president, has been in the investment business since 1979 and has
served as the fund's portfolio manager since 1985. Other portfolio managers on
the team are Thomas Finucane, vice president, who has been in the investment
business since joining the adviser in 1990 and Thomas Goggins, senior vice
president, who has been in the investment business since 1986 and joined the
adviser in 1995.

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

GOAL AND STRATEGY

[Clip Art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in stocks that are diversified with regard to industries and
issuers. The fund favors stocks of companies whose operating earnings and
revenues have grown more than twice as fast as the gross domestic product over
the past five years, although not all stocks in the fund's portfolio will meet
this criterion.

PORTFOLIO SECURITIES

[Clip Art] The portfolio invests primarily in the common stocks of U.S.
companies. It may also invest in warrants, preferred stocks and convertible debt
securities.

For liquidity and flexibility, the fund may invest up to 35% of net assets in
investment-grade short-term securities. In abnormal market conditions, it may
invest more than 35% in these securities as a defensive tactic. The fund may
also 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. To the extent that the fund invests in
higher-risk securities, it takes on additional risks that could adversely affect
its performance. Before you invest, please read "More about risk" starting on
page 27.

PORTFOLIO MANAGEMENT

[Clip Art] Anurag Pandit, CFA, is leader of the fund's portfolio management
team. A second vice president of the adviser, Mr. Pandit has been a member of
the management team since joining John Hancock Funds in April 1996. He assumed
leadership of the team on January 1, 1997. Mr. Pandit has been in the investment
business since 1984.

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. Because no Class C shares were outstanding during the past year, Class
C expenses are based on Class B expenses. Future expenses may be greater or
less.

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%.

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.

Regional Bank Fund

This fund is temporarily closed to new investments except for existing accounts
(see the statement of additional information).

REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST II
                                TICKER SYMBOL    CLASS A: FRBAX   CLASS B: FRBFX
- --------------------------------------------------------------------------------
GOAL AND STRATEGY

[Clip Art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in regional banks and lending institutions, including:
o  commercial and industrial banks
o  savings and loan associations
o  bank holding companies

These financial institutions provide full-service banking, have primarily
domestic assets and are typically based outside of New York City and Chicago.
They may or may not be members of the Federal Reserve, and their deposits may or
may not be FDIC-insured.

Under normal circumstances, the fund invests at least 65% of assets in these
companies; it may invest up to 35% of assets in other financial services
companies, including lending companies and money center banks. The fund may
invest up to 5% of net assets in stocks of non-financial services companies and
up to 5% in junk bonds issued by banks.

Because regional banks typically pay regular dividends, moderate income is an
investment goal.

PORTFOLIO SECURITIES

[Clip Art] The fund invests primarily in the common stocks of U.S. companies. It
may also invest in warrants, preferred stocks and investment-grade convertible
debt securities, as well as foreign stocks.

For liquidity and flexibility, the fund may place up to 15% of net assets in
cash or in investment-grade short-term securities. In abnormal market
conditions, it may invest up to 80% in these securities as a defensive tactic.
The fund may also 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 in a single
industry, its performance is largely dependent on the industry's performance,
which may differ in direction and degree from that of the overall stock market.
Falling interest rates or deteriorating economic conditions can adversely affect
the performance of bank stocks, while rising interest rates will cause a decline
in the value of any debt securities the fund holds. Before you invest, please
read "More about risk" starting on page 27.

PORTFOLIO MANAGEMENT

[Clip Art] James K. Schmidt, CFA, leads the fund's management team. Mr. Schmidt,
executive vice president, has been in the investment business since 1979 and has
served as the fund's portfolio manager since 1985. Other portfolio managers on
the team are Thomas Finucane, vice president, who has been in the investment
business since joining the adviser in 1990 and Thomas Goggins, senior vice
president, who has been in the investment business since 1986 and joined the
adviser in 1995.

(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.

                                TICKER SYMBOL    CLASS A: JHNSX   CLASS B: SPQBX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip Art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in small-capitalization companies and companies in situations
offering unusual or non-recurring opportunities. Under normal circumstances, the
fund invests at least 65% of assets in a diversified portfolio of these
companies. The fund looks for companies that dominate an emerging industry or
hold a growing market share in a fragmented industry, and that have demonstrated
annual earnings and revenue growth of at least 25%, self-financing capabilities
and strong management. The fund does not invest for income.

PORTFOLIO SECURITIES

[Clip Art] The fund invests primarily in the common stocks of U.S. and foreign
companies. It may also invest in warrants, preferred stocks and investment-grade
convertible debt securities.

For liquidity and flexibility, the fund may place up to 35% of assets in cash or
in investment-grade short-term securities. In abnormal market conditions, it may
invest more than 35% 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. Stocks of small-capitalization and
special-situation companies carry higher risks than stocks of larger companies.
This is because these companies: 
o  may lack proven track records 
o  may be dependent on a small number of products or services 
o  may be undercapitalized
o  may have highly priced stocks that are sensitive to adverse news

   
In addition, stocks of these companies are often traded in low volumes, which
can increase market and liquidity risks. Before you invest, please read "More
about risk" starting on page 27.
    

MANAGEMENT/SUBADVISER

[Clip Art] Michael P. DiCarlo is responsible for the fund's day-to-day
investment management. He has served as the fund's portfolio manager since
January 1988, and has been in the investment business since 1984. He is
currently one of three principals in DFS Advisors, LLC, which was founded in
1996 and serves as subadviser to the fund.

This fund will be closed to new investors at the end of the day its total assets
reach $2.5 billion. Further investments will be limited to existing accounts.

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

GOAL AND STRATEGY

[Clip Art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in those economic sectors that appear to have a higher than
average earning potential.

   
Under normal circumstances, at least 75% of the fund's equity securities is
invested within five or fewer sectors (e.g., financial services, energy,
technology). At times, the fund may focus on a single sector. The fund first
determines the inclusion and weighting of sectors, using macroeconomic as well
as other factors, then selects portfolio securities by seeking the most
attractive companies. The fund may add or drop sectors.
    

PORTFOLIO SECURITIES

[Clip Art] The fund invests primarily in common stocks of U.S. and
foreign companies of any size. It may also invest in warrants, preferred stocks,
convertible debt securities, U.S. Government securities and corporate bonds
rated at least BBB/Baa, or equivalent, and may invest in certain higher-risk
securities. The fund also may make short sales of securities and may engage in
other investment practices.

For liquidity and flexibility, the fund may place assets in cash or invest in
investment-grade short-term securities.

RISK FACTORS

   
[Clip Art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. By focusing on a relatively small number
of sectors or issuers, the fund runs the risk that any factor influencing those
sectors or issuers will have a major effect on performance. The fund may invest
in companies with smaller market capitalizations, which represent higher
near-term risks than larger capitalization companies. These factors make the
fund likely to experience higher volatility than most other types of growth
funds. Before you invest, please read "More about risk" starting on page 27.
    

PORTFOLIO MANAGEMENT

[Clip Art] Barbara C. Friedman, CFA, is leader of the fund's portfolio
management team. A senior vice president of the adviser, Ms. Friedman has been a
member of the management team since joining John Hancock Funds in January 1998.
Ms. Friedman has been in the investment business since 1973.

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. Because no Class C shares were outstanding during the past year, Class
C expenses are based on Class B expenses. Future expenses may be greater or
less.

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%.

CHOOSING A SHARE CLASS

   
All John Hancock growth funds offer two classes of shares, Class A and Class B.
In addition, Class C shares are available for Emerging Growth Fund, Growth Fund
and Special Opportunities Fund. Each class has its own cost structure, as
outlined below, allowing you to choose the one that best meets your
requirements. For more details, see "How sales charges are calculated." Your
financial representative can help you decide which share class is best for
you.

- --------------------------------------------------------------------------------
 Class A - for all funds
- --------------------------------------------------------------------------------
   o  Front-end sales charges. There are several ways to reduce these charges,
      described under "Sales charge reductions and waivers" on the following
      page.
   o  Lower annual expenses than Class B and Class C shares.

    
- --------------------------------------------------------------------------------
 Class B - for all funds
- --------------------------------------------------------------------------------
   o  No front-end sales charge; all your money goes to work for you right away.
   o  Higher annual expenses than Class A shares.
   o  A contingent deferred sales charge that declines from 5% over 6 years.
   o  Automatic conversion to Class A shares after eight years, thus reducing
      future annual expenses.

- --------------------------------------------------------------------------------
 Class C - for selected funds
- --------------------------------------------------------------------------------

   
Applies to Emerging Growth Fund, Growth Fund and Special Opportunities Fund.
   o  No front-end sales charge; all your money goes to work for you right away.
   o  Higher annual expenses than Class A shares.
   o  A 1% contingent deferred sales charge on shares sold within one year of
      purchase.
   o  No automatic conversion to Class A shares, so the fund's annual expenses
      continue at the same level throughout the life of your investment.
    

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

Special Equities Fund offers Class Y shares, which have their own expense
structure and are available to financial institutions only. Call Signature
Services for more information (see back cover of this prospectus).
- --------------------------------------------------------------------------------
It is presently the policy of Signature Services not to accept any order of
$100,000 or more for Class B shares or any order of $1 million or more for Class
C shares. In these circumstances it would be more beneficial for the investor to
purchase Class A shares.

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

HOW SALES CHARGES ARE CALCULATED

Class A Sales charges are as follows:

 $50,000 - $99,999          4.50%           4.71%
 $100,000 - $249,999        3.50%           3.63%
 $250,000 - $499,999        2.50%           2.56%
 $500,000 - $999,999        2.00%           2.04%
 $1,000,000 and over        See below

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:

 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 six years of buying them. 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:

 6th year                        1.00%
 After 6 years                   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.

Class C Shares are offered at their net asset value per share, without any
initial sales charge. However, you may be charged a contingent deferred sales
charge (CDSC) of 1% on shares you sell within one year of purchase. 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.

CDSC calculations are based on the number of shares involved, not on the value
of your account. Each time you place a request to sell shares we will first sell
any shares in your account that carry no CDSC. 

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

- --------------------------------------------------------------------------------
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 to an
existing account.

Group Investment Program A group may be treated as a single purchaser under the
accumulation and combination privileges. Each investor has an individual
account, but the group's investments are lumped together for sales charge
purposes, making the investors potentially eligible for reduced sales charges.
There is no charge, no obligation to invest (although initial investments must
total at least $250) and individual investors may close their account 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 each 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 17
<PAGE>

Waivers for certain investors Class A shares may be offered without front-end
sales charges or CDSCs to various individuals and institutions, including:

o  government entities that are prohibited from paying mutual fund sales charges
o  financial institutions or common trust funds investing $1 million or more for
   non-discretionary accounts
o  selling brokers and their employees and sales representatives
o  financial representatives utilizing fund shares in fee-based investment
   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 members (one-year
   CDSC applies)

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.

TRANSACTION POLICIES

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

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

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

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

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

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

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

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

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

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

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

DIVIDENDS AND ACCOUNT POLICIES

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

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

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

o  in all other circumstances, every quarter

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

Dividends The funds generally distribute most or all of their net earnings in
the form of dividends. Any capital gains are distributed annually. Regional Bank
Fund typically pays income dividends quarterly and Financial Industries Fund
typically pays income dividends annually. The other funds do not usually pay
income dividends.

22 YOUR ACCOUNT
<PAGE>

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

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

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

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.

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 growth 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 growth 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").

24 FUND DETAILS


<PAGE>

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

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

Investment goals Except for Emerging Growth Fund, Financial Industries Fund and
Special Opportunities Fund, each fund's investment goal is fundamental and may
only be changed with shareholder approval.


   
Diversification All of the growth 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 and Class C
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.

   
Class C shares.  The Class C shares began operations after the 1997 fiscal year.
Therefore, there are no unreimbursed expenses to report.
    

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 page 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 growth fund will be positive over any period of time -- days, months or
years. However, stock funds as a category have historically performed better
over the long term than bond or money market funds.

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

TYPES OF INVESTMENT RISK

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

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

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

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 the price originally paid for it, or 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.

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 under a Declaration of Trust dated
December  2, 1996.  Prior to  December  2,  1996,  the Fund was a series of John
Hancock Technology Series,  Inc., a Maryland  corporation.  On December 2, 1996,
the Trust assumed the Registration  Statement of John Hancock Technology Series,
Inc.  Prior to December  22,  1994,  the Fund was called  Transamerica  Emerging
Growth Fund.

The  Fund  is  managed  by  John  Hancock  Advisers,  Inc.  (the  "Adviser"),  a
wholly-owned  indirect  subsidiary of John Hancock Mutual Life Insurance Company
(the "Life  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 Fund seeks long-term  growth of capital  appreciation.  To pursue this goal,
the Fund invests in emerging  companies  (market  capitalization of less than $1
billion).  In normal  circumstances,  the Fund  will  invest at least 80% of its
assets in these companies.  Current income is not a factor of consequence in the
selection of stocks for the Fund.

In order to achieve its  objective,  the Fund invests in a diversified  group of
companies  whose growth rates are expected to  significantly  exceed that of the
average  industrial  company.  It  invests  in  these  companies  early in their
corporate life cycle before they become widely  recognized  and well known,  and
while  their  reputations  and  track  records  are  still  emerging  ("emerging
companies").  Consequently, the Fund invests in the stocks of emerging companies
whose  capitalization,  sales and earnings are smaller than those of the Fortune
500 companies.  Further,  the Fund's  investments in emerging company stocks may
include  those of more  established  companies  which offer the  possibility  of
rapidly accelerating earnings because of revitalized  management,  new products,
or structural changes in the economy.

The nature of  investing  in emerging  companies  involves  greater risk than is
customarily  associated  with  investments  in more  established  companies.  In
particular,  the value of  securities of emerging  companies  tends to fluctuate
more widely than other types of investments.  Because emerging  companies may be
in the early stages of their development,  they may be dependent on a relatively
few products or services. They may also lack adequate capital reserves or may be
dependent on one or two  management  individuals.  Their stocks are often traded
"over-the-counter"  or on a regional exchange,  and may not be traded in volumes
typical of trading on a national exchange.  Consequently, the investment risk is
higher than that normally associated with larger, older, better-known companies.
In order to help reduce this risk,  the Fund  allocates  its  investments  among
different industries.

Most of the Fund's  investments will be in equity securities of U.S.  companies.
However,  since many emerging companies are located outside the United States, a
significant  portion of the Fund's  investments may  occasionally be invested in
equity securities of non-U.S. companies.


                                       2

<PAGE>

While the Fund will invest primarily in emerging  companies,  the balance of the
Fund's assets may be invested in: (1) other common stocks; (2) preferred stocks;
(3) convertible securities (up to 10% of the Fund's total assets may be invested
in convertible securities rated as low as "B" by Standard & Poor's Ratings Group
("S&P")  or  Moody's  Investors  Service,   Inc.  ("Moody's")  or,  if  unrated,
determined by John Hancock  Advisers,  Inc. (the  "Adviser") to be comparable in
quality to those rated "B"; (4) warrants; and (5) debt obligations of the U.S.
Government, its agencies and instrumentalities.

In order to provide  liquidity for the purchase of new investments and to effect
redemptions of its shares,  the Fund will invest a portion of its assets in high
quality,  short-term debt  securities  with remaining  maturities of one year or
less, including U.S. Government  securities,  certificates of deposit,  bankers'
acceptances,  commercial paper, corporate debt securities and related repurchase
agreements.

During  periods of unusual  market  conditions  when the Adviser  believes  that
investing for temporary  defensive  purposes is appropriate,  part or all of the
Fund's  assets may be invested in cash or cash  equivalents  consisting  of: (1)
obligations of banks (including  certificates of deposit,  bankers'  acceptances
and repurchase  agreements)  with assets of $100,000,000 or more; (2) commercial
paper rated within the two highest rating categories of a nationally  recognized
rating  organization;  (3) investment  grade  short-term  notes; (4) obligations
issued  or  guaranteed  by  the  U.S.  Government  or any  of  its  agencies  or
instrumentalities; and (5) related repurchase agreements.

Investment In Foreign  Securities.  The Fund may invest in securities of foreign
issuers including  securities 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 United
States  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.

Foreign  Securities and Investments in Emerging Markets.  The Fund may invest in
securities of foreign issuers, including debt and equity securities of corporate
and  governmental  issuers in countries  with  emerging  economies or securities
markets.

The  securities  markets of many  countries  have in the past  moved  relatively
independent 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

 
                                        3

<PAGE>

direction as the securities markets in a particular country. As a result, market
gains may be offset by unfavorable exchange rate fluctuations.

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

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

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

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

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


                                       4

<PAGE>

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  increase  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 erratic price movements.

Foreign Currency Transactions. The foreign currency exchange transactions of the
Fund  may be  conducted  on a spot  (i.e.,  cash)  basis  at the  spot  rate for
purchasing or selling currency  prevailing in the foreign  exchange market.  The
Fund may enter  into  forward  foreign  currency  exchange  contracts  involving
currencies of the different  countries in which it may invest as a hedge against
possible variations in the foreign exchange rate between these currencies.  This
is accomplished  through contractual  agreements to purchase or sell a specified
currency at a specified  future date and price set at the time of the  contract.
The Fund's  dealings in forward  foreign  currency  contracts will be limited to
hedging either specific  transactions or portfolio positions.  The Fund will not
attempt to hedge all of its foreign  portfolio  positions and will not engage in
speculative forward currency transactions.

If the Fund enters into a forward  contract to purchase  foreign  currency,  its
custodian  bank  will  segregate  cash  or  liquid  securities,  of any  type or
maturity,  (i.e.  securities  rated more of the top three rating  categories  by
Moody's on S&P) in a  separate  account  of the Fund in an amount  necessary  to
complete the forward contract. These assets will be marked to market daily, and,
if the value of the securities in the separate account declines, additional cash
or  liquid  securities  will be added so that the value of the  account  will be
equal to the amount of the Fund's commitments in contracts.

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 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,  an 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



                                       5


<PAGE>

net results on its portfolio  transactions.  There is generally less  government
supervision and regulation of securities  exchanges,  brokers and listed issuers
than in the United States.

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

The  dividends,  and, 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.

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

The cost to the Fund of  engaging  in  foreign  currency  exchange  transactions
varies with 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.

Lower Rated High Yield Debt  Obligations.  The Fund may invest in high yielding,
fixed  income  securities  rated  below  investment  grade rated Baa or lower by
Moody's and BBB or lower by S&P.  See  Appendix A for a  description  of ratings
assigned by Moody's and S&P.

Ratings are based largely on the historical  financial  condition of the issuer.
Consequently,  the rating assigned to any particular security is not necessarily
a reflection of the issuer's current financial condition, which may be better or
worse than the rating would indicate.

The values of  lower-rated  securities  generally  fluctuate  more than those of
high-rated  securities.  In  addition,  the  lower  rating  reflects  a  greater
possibility of an adverse change in financial condition affecting the ability of
the issuer to make  payments of interest  and  principal.  Although  the adviser
seeks to minimize these risks through  diversification,  investment analysis and
attention to current  developments  in interest  rates and economic  conditions,
there can be no assurance  that the Adviser will be  successful  in limiting the
Fund's exposure to the risks associated with lower rated securities. Because the
Fund invests in securities in the lower rated categories, the achievement of the
Fund's goals is more  dependent on the Adviser's  ability than would be the case
if the Fund were investing in securities in the higher rated categories.

The Fund may invest in  pay-in-kind  (PIK)  securities,  which pay  interest  in
either cash or additional  securities,  at the issuer's option,  for a specified
period.  The Fund also may invest in zero coupon bonds,  which have a determined
interest  rate,  but payment of the interest is deferred  until  maturity of the
bonds.  Both  types of bonds may be more  speculative  and  subject  to  greater
fluctuations in value than  securities  which pay interest  periodically  and in
cash, due to changes in interest rates.



                                       6

The market value of debt securities which carry no equity participation  usually
reflects yields  generally  available on securities of similar quality and type.
When such yields decline,  the market value of a portfolio  already  invested at
higher yields can be expected to rise if such  securities are protected  against
early call. In general,  in selecting  securities  for its  portfolio,  the Fund
intends to seek  protection  against  early  call.  Similarly,  when such yields
increase,  the market value of a portfolio  already invested at lower yields can
be expected to decline.  The Fund's  portfolio may include debt securities which
sell at substantial  discounts  from par. These  securities are low coupon bonds
which,  because of their  lower  acquisition  cost tend to sell on a yield basis
approximating current interest rates during periods of high interest rates.

Repurchase  Agreements.  In a repurchase agreement the Fund buy a security for a
relatively  short  period  (usually  not more than  seven  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,  a 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.  The
Fund will not invest in a repurchase agreement maturing in more than seven days,
if such  investment,  together with other illiquid  securities  held by the Fund
(including restricted securities) would exceed 10% of the Fund's net assets.

Reverse Repurchase  Agreements.  The Fund may also enter into reverse repurchase
agreements which involve the sale of government securities held in its portfolio
to a bank  with an  agreement  that the Fund will buy back the  securities  at a
fixed future date at a fixed price plus an agreed  amount of interest  which may
be  reflected  in  the  repurchase  price.  Reverse  repurchase  agreements  are
considered to be borrowings by the Fund. Reverse  repurchase  agreements involve
the risk that the market value of securities purchased by 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.  To minimize  various  risks
associated  with reverse  repurchase  agreements,  the Fund will  establish  and
maintain  with the Fund's  custodian  a separate  account  consisting  of liquid
securities,  of any  type or  maturity,  in an  amount  at  least  equal  to the
repurchase  prices of the securities (plus any accrued  interest  thereon) under
such  agreements.  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.  The Fund
will not enter into reverse repurchase  agreements exceeding in the aggregate 33
1/3% of the market value of its total  assets.  The Fund will enter into reverse
repurchase  agreements  only with  federally  insured  banks or savings and loan
associations  which  are  approved  in  advance  as  being  creditworthy  by the
Trustees. Under procedures established by the Trustees, the Adviser will monitor
the creditworthiness of the banks involved.

<PAGE>

Restricted  Securities.  The Fund  will not  invest  more  than 10% of its total
assets in securities that are not registered ("restricted securities") under the
Securities Act of 1933 (the "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 10% of its net assets in illiquid investments.  If the
Trustees  determines,  based upon a continuing review of the trading markets for
specific 4(2) paper or Rule 144A securities, that they are liquid, they will not
be subject to the 10% limit on  illiquid  investments.  The  Trustees  may adopt
guidelines  and delegate to the Adviser the daily  function of  determining  and
monitoring the liquidity of restricted securities.  The Trustees,  however, will
retain   sufficient   oversight   and  be   ultimately   responsible   for   the
determinations.  The Trustees will carefully  monitor 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.

<PAGE>

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 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




                                      9
<PAGE>

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

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



                                       10
  
<PAGE>

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 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 fixed income securities,  stocks indices or currencies,  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


                                       11

<PAGE>

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  (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  qualification  as a
regulated investment company for federal income tax purposes.

Transactions  in futures  contracts  and  options on futures  involve  brokerage
costs,  require  margin  deposits  and,  in the case of  contracts  and  options
obligating the Fund to purchase  securities 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


                                       12


<PAGE>

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,  stock 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.  The
Fund may not lend portfolio securities having a total value exceeding 30% of its
total assets.

Rights  and  Warrants.  The Fund may  purchase  warrants  and  rights  which are
securities  permitting,  but  not  obligating,  their  holder  to  purchase  the
underlying  securities at a predetermined price subject to the Fund's Investment
Restriction.  Generally,  warrants and stock  purchase  rights do not carry with
them the right to receive  dividends or exercise  voting  rights with respect to
the underlying securities, and they do not represent any rights in the assets of
the issuer.  As a result, an investment in warrants and rights may be considered
to entail greater  investment risk than certain other types of  investments.  In
addition,  the value of 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


                                       13


<PAGE>

month or more after the purchase. In a forward commitment transaction,  the Fund
contracts  to  purchase  securities  for a fixed  price at a future  date beyond
customary settlement time.

When the Fund engages in forward  commitment and  when-issued  transactions,  it
relies on the seller to consummate the transaction. The failure of the issuer or
seller to  consummate  the  transaction  may  result in the  Fund's  losing  the
opportunity  to obtain a price  and yield  considered  to be  advantageous.  The
purchase  of  securities  on a  when-issued  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,  or 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.  As a matter of  nonfundamental  policy,  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
the Fund's 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)      Borrow money in an amount in excess of 33-1/3% of its total assets, and
         then  only  as a  temporary  measure  for  extraordinary  or  emergency
         purposes (except that it may enter into a reverse repurchase  agreement
         within the limits  described in the Prospectus or this SAI), or pledge,
         mortgage or hypothecate an amount of its assets (taken at market value)
         in excess of 15% of its total  assets,  in each case taken at the lower
         of  cost  or  market  value.  For  the  purpose  of  this  restriction,
         collateral  arrangements  with respect to options,  futures  contracts,
         options on futures  contracts and collateral  arrangements with respect
         to initial and variation margins are not considered a pledge of assets.

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


                                       14


<PAGE>

(3)      Purchase or retain real estate (including limited partnership interests
         but excluding  securities of companies,  such as real estate investment
         trusts,  which deal in real estate or interests  therein and securities
         secured by real estate),  or mineral  leases,  commodities or commodity
         contracts, precious metals (except contracts for the future delivery of
         fixed income  securities,  stock index and currency futures and options
         on such  futures)  in the  ordinary  course of its  business.  The Fund
         reserves  the  freedom  of action  to hold and to sell  real  estate or
         mineral leases, commodities or commodity contracts acquired as a result
         of the ownership of securities.

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

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

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

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

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

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

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


                                       15


<PAGE>

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

(12)     Issue any senior  security  (as that term is defined in the  Investment
         Company Act of 1940) if such issuance is specifically prohibited by the
         1940 Act or the rules and regulations promulgated  thereunder.  For the
         purpose of this  restriction,  collateral  arrangements with respect to
         options,  futures  contracts  and  options  on  futures  contracts  and
         collateral  arrangements  with respect to initial and variation margins
         are not deemed to be the issuance of a senior security.

(13)     Concentrate  its investments in any particular  industry,  but if it is
         deemed appropriate for the attainment of its investment objective,  the
         Fund may invest up to 25% of its assets  (taken at market  value at the
         time of each investment) in securities of issuers in any one industry.

(14)     Purchase voting securities of any issuer if such purchase,  at the time
         thereof, would cause more than 10% of the outstanding voting securities
         of such issuer to be held by the Fund;  or purchase  securities  of any
         issuer if such  purchase at the time thereof  would cause more than 10%
         of any class of securities  of such issuer to be held by the Fund.  For
         this  purpose all  indebtedness  of an issuer  shall be deemed a single
         class and all  preferred  stock of an  issuer  shall be deemed a single
         class.  In applying these  limitations,  a guarantee of a security will
         not be considered a security of the guarantor,  provided that the value
         of all securities issued or guaranteed by that guarantor,  and owned by
         the  Fund,  does  not  exceed  10%  of  the  Fund's  total  assets.  In
         determining  the issuer of a  security,  each state and each  political
         subdivision   agency,  and  instrumentality  of  each  state  and  each
         multi-state  agency  of which  such  state is a  member  is a  separate
         issuer.  Where  securities  are backed only by assets and revenues of a
         particular  instrumentality,  facility or  subdivision,  such entity is
         considered the issuer.

Other Operating Policies

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

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

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.

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

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



                                       26

<PAGE>

meetings;   trade   association   membership;   insurance   premiums;   and  any
extraordinary expenses.

As compensation for its services under the Advisory Agreement, the Fund pays the
Adviser  monthly  a fee,  equal on an annual  basis to 0.75%,  based on a stated
percentage of the average daily net assets of the Fund.

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

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

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

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 that
its  continuance  is approved  annually both (i) by the holders of a majority of
the outstanding voting securities of the Trust or by the Trustees, and (ii) by a
majority of the  Trustees who are not parties to the  Agreement  or  "interested
persons" of any such  parties.  Both  agreements  may be  terminated  on 60 days
written notice by any party or by vote of a majority of the  outstanding  voting
securities of the Fund and will terminate automatically if assigned.

Administrative  Services  Agreement.  The Fund was a party to an  administrative
services  agreement with  Transamerica  Fund  Management  Company  ("TFMC") (the
"Services  Agreement"),   pursuant  to  which  TFMC  performed  bookkeeping  and


                                       27

<PAGE>

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

For the fiscal  years ended  October  31,  1995 and 1994,  the Fund paid to TFMC
(pursuant to the Services Agreement) $34,231 and $222,044, respectively.

Accounting and Legal Services Agreement.  The Trust, on behalf of the fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this agreement,  the Adviser  provides the Fund with certain tax,  accounting
and legal  services.  For the fiscal years ended October 31, 1997 and 1996,  the
Fund paid the Adviser  $125,076 and $101,864,  respectively,  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  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 Fund 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 or Class C  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 period ended October 31, 1997, 1996 and 1995 were $403,208,  $795,886 and
$604,527, respectively, and $62,078, $109,314 and $67.705, 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 each class of
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 0.25% for Class A shares  and 1.00% for Class B
and Class C shares 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


                                       28

<PAGE>

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 and Class C 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 and Class C Plans  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 and
Class C Plans as a liability of the Fund because the Trustees may  terminate the
Class B and/or Class C Plans at any time.  For the fiscal year ended October 31,
1997,  an  aggregate of  $12,476,287  of  distribution  expenses or 2.75% of the
average  net  assets of the Class B shares of the Fund,  was not  reimbursed  or
recovered by John Hancock Funds through the receipt of deferred sales charges or
Rule 12b-1 fees in prior  periods.  Class C shares did not  commence  operations
until June 1, 1998; therefore, there are no unreimbursed expenses to report.
    

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, Class B and Class C 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



                                       29

<PAGE>

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.

   
During 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: Class C shares did not commence operations until June 1, 1998;  therefore,
there are no unreimbursed expenses to report.

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 mean
between the current closing bid and asked prices.

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

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


                                       30


<PAGE>

On any day an international  market is closed and the New York Stock Exchange is
open,  any foreign  securities  will be valued at the prior day's close with the
current day's  exchange  rate.  Trading of foreign  securities may take place on
Saturdays and U.S.  business holidays on which the Fund's NAV is not calculated.
Consequently,  the  Fund's  portfolio  securities  may  trade and the NAV of the
Fund's  redeemable  securities  may be  significantly  affected  on days  when a
shareholder has no access to the Fund.

INITIAL SALES CHARGE ON CLASS A SHARES

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

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

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

o        A member of a class action lawsuit against  insurance  companies who is

o        Retirement plans participating in Merrill Lynch servicing programs,  if

         at the date the Plan  Sponsor  signs the  Merrill  Lynch  Recordkeeping
         Service  Agreement.  See your Merrill Lynch  financial  consultant  for
         further information.

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

         Amount Invested                                    CDSC Rate

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

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

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

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

Accumulation Privilege.  Investors (including investors combining purchases) who
are  already  Class A  shareholders  may also  obtain the benefit of the reduced
sales charge by taking into account not only the amount then being  invested but
also the  purchase  price or  current  value of the  Class A shares  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


                                       32

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

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

   
DEFERRED SALES CHARGE ON CLASS B AND CLASS C SHARES

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

Contingent Deferred Sales Charge.  Class B and Class C shares which are redeemed
within  six  or one  year  of  purchase,  respectively,  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 or Class C 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  and  Class  C  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.


                                       33


<PAGE>

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

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)
    OMinus proceeds of 10 shares not subject to CDSC 
     (dividend reinvestment)                                            (120.00)
                                                                        -------
    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 and  Class C  shares,  such as the  payment  of  compensation  to select
Selling  Brokers for selling Class B and Class C shares.  The combination of the
CDSC and the  distribution  and service fees facilitates the ability of the Fund
to sell the Class B and Class C 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 and Class C shares and of Class A shares that are subject
to CDSC, unless indicated otherwise, in the circumstances defined below:
    

For all account types:

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

                                       34

*        Redemptions  made under the  Reinstatement  Privilege,  as described in

*        Redemptions  of  Class  B and  Class C  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.

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
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 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 and Class C shares and because  redemptions  are taxable

                                       37

<PAGE>

events.  Therefore,  a shareholder should not purchase 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.

  
                                       38

<PAGE>

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

DESCRIPTION OF THE FUND'S SHARES

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

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
each class of 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 each class will be borne  exclusively
by that class; (ii) Class B and Class C shares will pay higher  distribution and
service  fees than Class A shares,  and (iii) each class of 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 which
class of 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 of
each class. 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 a request for 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 Trust's  Declaration  of Trust  contains an express
disclaimer of  shareholder  liability for acts,  obligations  and 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 the 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 in the future.  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%  non-deductible  Federal  excise tax on certain
amounts not distributed (and not treated as having been distributed) on a timely
basis in accordance  with annual  minimum  distribution  requirements.  The Fund
intends under normal  circumstances  to seek to avoid or minimize  liability for
such tax by satisfying such distribution requirements.

Distributions  from the  Fund's  current or  accumulated  earnings  and  profits
("E&P") will be taxable  under the Code for investors who are subject to tax. If
these  distributions  are  paid  from the  Fund's  "investment  company  taxable
income," they will be taxable as ordinary income;  and if they are paid from the
Fund's "net capital  gain," they will be taxable as capital  gain.  (Net capital
gain is the excess (if any) of net  long-term  capital gain over net  short-term
capital loss,  and investment  company  taxable income is all taxable income and
capital  gains,  other than 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


                                       40

<PAGE>

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.

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  such
companies or gain from the sale of stock in such  companies,  even if all income
or gain actually received by the Fund is timely distributed to its shareholders.
The Fund  would not be able to pass  through to its  shareholders  any credit or
deduction  for such a tax. 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 holdings in passive foreign investment  companies or
make an available  election to minimize its tax liability or maximize its return
from these investments.

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.

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.  The Fund does not expect to  qualify  to pass such taxes  through to its
shareholders,  who  consequently  will not take such taxes into account on their
own tax returns.  However,  the Fund will deduct such taxes in  determining  the
amount it has available for distribution to shareholders.

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


                                       41


<PAGE>

unrealized  appreciation in the Fund's portfolio or undistributed taxable income
of the Fund.  Consequently,  subsequent  distributions 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.

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  shares of the Fund or  another  John  Hancock  Fund are
subsequently  acquired  without  payment  of a  sales  charge  pursuant  to  the
reinvestment  or exchange  privilege.  Such  disregarded  load will result in an
increase in the  shareholder's  tax basis in the shares  subsequently  acquired.
Also,  any loss  realized on a redemption  or exchange may be  disallowed to the
extent the shares  disposed of are replaced with other shares of the 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 an  election  to reinvest  dividends  in
additional  shares.  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
capital  loss in any year to offset its 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


                                       42

<PAGE>

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 the stock of such  corporations  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) 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 the excess (if any) of a corporate  shareholder's  adjusted  current
earnings over its alternative  minimum  taxable  income,  which may increase its
alternative  minimum  tax  liability,   if  any.  Additionally,   any  corporate
shareholder  should consult its tax adviser  regarding the possibility  that its
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 to zero,  that current  recognition of income
would be required.

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 payment.  The mark to
market  rules or  constructive  sale  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.

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


                                       43

<PAGE>

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. These transactions may therefore
affect  the  amount,  timing  and  character  of  the  Fund's  distributions  to
shareholders. Certain of such transactions may also cause the Fund to dispose of
investments  sooner than would otherwise have occurred.  The Fund will take into
account the special tax rules (including  consideration of available  elections)
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  distributions  from,  the Fund in their  particular
circumstances.

Non-U.S.  investors  not engaged in a U.S.  trade or  business  with which their
investment in the Fund is effectively  connected will be subject to U.S. Federal
income  tax  treatment  that is  different  from  that  described  above.  These
investors may be subject to nonresident alien withholding tax at the rate of 30%
(or a lower rate under an applicable tax treaty) on amounts  treated as ordinary
dividends  from 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.

                                       44


<PAGE>

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

   
As of October 31, 1997, the average annual returns for the Fund's Class A shares
for the one year and five year  periods and since  inception  on August 22, 1991
were 17.18 %,  18.39% and 17.07%,  respectively.  As of October  31,  1997,  the
average  annual total  returns of the Class B shares of the Fund for the one and
five year periods and the  life-of-the  Fund since inception on October 26, 1987
were  17.44 %,  18.49%  and  20.63%,  respectively.  Class C shares  of the Fund
commenced  operations on June 1, 1998;  therefore  there is average annual total
return to report.
    

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

             n ______
          T=\ /ERV/P - 1




Where:

P =               a hypothetical initial investment of $1,000.
T =               average annual total return.
n =               number of years.
ERV               = ending redeemable value of 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 each  class,  this  calculation
assumes the maximum  sales charge is included in the initial  investment  or the
CDSC applied at the end of the period,  respectively.  This calculation  assumes
that all dividends and  distributions  are  reinvested at net asset value on the
reinvestment dates during the period.  The "distribution  rate" is determined by
annualizing the result of dividing the declared dividends of the Fund during the
period stated by the maximum offering price or net asset value at the end of the
period.  Excluding the Fund's sales charge from the distribution rate produces a
higher rate.


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

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

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

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

BROKERAGE ALLOCATION

Decisions  concerning  the  purchase and sale of  portfolio  securities  and the
allocation  of  brokerage  commissions  are  made  by the  Adviser  pursuant  to
recommendations made by its investment committee of the Adviser,  which consists
of officers  and  Trustees who are  interested  persons of the Fund.  Orders for
purchases and sales of securities  are placed in a manner which,  in the opinion
of the Adviser,  will offer the best price and market for the  execution of each
transaction.  Purchases from underwriters of portfolio  securities may include a
commission  or  commissions  paid by the issuer and  transactions  with  dealers
serving as market  makers  reflect a "spread."  Debt  securities  are  generally
traded on a net basis through dealers acting for their own account as principals
and not as brokers; no brokerage commissions are payable on 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  Dealer,  Inc.
and other  policies  that the Trustees may  determine,  the Adviser may consider
sales of shares of the Fund as a factor in the  selection of  broker-dealers  to
execute the Fund's portfolio transactions.

To the extent  consistent  with the foregoing,  the Fund will be governed in the
selection of brokers and dealers,  and the  negotiation of brokerage  commission
rates and dealer  spreads,  by the  reliability  and  quality  of the  services,


                                       46

<PAGE>

including primarily the availability and value of research  information and to a
lesser extent statistical  assistance  furnished to the Adviser of the Fund, and
their value and expected  contribution to the performance of the Fund. It is not
possible to place a dollar value on information and services to be received from
brokers and dealers,  since it is only  supplementary to the research efforts of
the  Adviser.  The receipt of  research  information  is not  expected to reduce
significantly  the  expenses  of  the  Adviser.  The  research  information  and
statistical  assistance  furnished  by brokers  and dealers may benefit the Life
Company or other  advisory  clients of the Adviser,  and  conversely,  brokerage
commissions and spreads paid by other advisory clients of the Adviser may result
in research information and statistical  assistance  beneficial to the Fund. The
Fund  will make no  commitments  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, their policies and practices in
this  regard  must be  consistent  with the  foregoing  and will at all times be
subject to review by the Trustees.  For the fiscal years ended October 31, 1997,
1996 and 1995,  the Fund paid  negotiated  brokerage  commissions of $1,118,124,
$459,477 and $263,019, respectively.

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  the  price  is
reasonable  in light of the services  provided and to policies that the Trustees
may adopt from time to time.  During the fiscal year ended October 31, 1997, the
Fund paid  commissions  of $95,744 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").  Pursuant to procedures established by the Trustees and
consistent  with the above  policy of obtaining  best net results,  the Fund may
execute portfolio  transactions with or through  Affiliated  Broker.  During 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 a clearing  broker for another  brokerage firm, and any customers of the
Affiliated  Broker not comparable to the Fund as determined by a majority of the
Trustees  who are not  interested  persons  (as  defined in the 1940 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


                                       47

<PAGE>

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,  the  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.

TRANSFER AGENT SERVICES

   
John Hancock Signature  Services,  Inc., 1 John Hancock Way, Suite 1000, Boston,
MA 02217- 1000, a wholly owned indirect  subsidiary of the Life Company,  is the
transfer  and  dividend  paying  agent  for the Fund.  The Fund  pays  Signature
Services an annual fee of $19.00 for each Class A shareholder account and $21.50
for each Class B  shareholder  account  and $20.50 for each Class C  shareholder
account.  The Fund also pays certain  out-of-pocket  expenses and these expenses
are  aggregated and charged to the Fund and allocated to each class on the basis
of their relative net asset values.
    

CUSTODY OF PORTFOLIO

Portfolio  securities  of the Fund are held  pursuant to a  custodian  agreement
between the Fund and  Investors  Bank & Trust  Company,  200  Clarendon  Street,
Boston,  Massachusetts  02116. Under the custodian  agreement,  Investors Bank &
Trust performs custody, portfolio and fund accounting services.

                                   APPENDIX A

                           Description of Bond Ratings

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

                         MOODY'S INVESTORS SERVICE, INC.

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

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

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

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

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

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



                                      A-1

<PAGE>



                         STANDARD & POOR'S RATINGS GROUP

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

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

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

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

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

Item 27.  Indemnification

     Section 4.3 of  Registrant's  Declaration  of Trust provides that (i) every
     person who is, or has been,  a Trustee,  officer,  employee or agent of the
     Trust  (including  any  individual  who serves at its request as  director,
     officer,  partner,  trustee or the like of another organization in which it
     has  any  interest  as a  shareholder,  creditor  or  otherwise)  shall  be
     indemnified  by the Trust,  or by one or more  Series  thereof if the claim
     arises from his or her conduct  with  respect to only such  Series,  to the
     fullest  extent  permitted  by law  against all  liability  and against all
     expenses  reasonably  incurred or paid by him in connection with any claim,
     action,  suit or  proceeding  in which he  becomes  involved  as a party or
     otherwise  by virtue of his being or having  been a Trustee or officer  and
     against amounts paid or incurred by him in the settlement thereof; and that
     (ii) the words "claim,"  "action,"  "suit," or "proceeding"  shall apply to
     all claims,  actions,  suits or  proceedings  (civil,  criminal,  or other,
     including  appeals),  actual or threatened;  and the words  "liability" and
     "expenses"  shall include,  without  limitation,  attorneys'  fees,  costs,
     judgments,   amounts  paid  in  settlement,   fines,  penalties  and  other
     liabilities.

     However,  no indemnification  shall be provided to a Trustee or officer (i)
     against any liability to the Trust, a Series thereof or the Shareholders by


                                      C-2

<PAGE>

     reason of willful  misfeasance,  bad faith,  gross  negligence  or reckless
     disregard  of the duties  involved in the conduct of his office;  (ii) with
     respect to any matter as to which he shall  have been  finally  adjudicated
     not to have acted in good faith in the  reasonable  belief  that his action
     was in the best  interest  of the Trust or a Series  thereof;  (iii) in the
     event  of  a  settlement  or  other   disposition  not  involving  a  final
     adjudication  resulting in a payment by a Trustee or officer,  unless there
     has been a  determination  that such  Trustee or officer  did not engage in
     willful  misfeasance,  bad faith, gross negligence or reckless disregard of
     the duties  involved  in the  conduct of his office by (A) a court by (B) a
     majority of the Non- interested  trustees or independent legal counsel,  or
     (C) a vote of the majority of the Fund's outstanding shares.

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

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

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

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

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


                                      C-3

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

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

Insofar as indemnification for liabilities under the Securities Act of 1933 (the
"Act")  may be  permitted  to  Trustees,  officers  and  controlling  persons of
Registrant  pursuant  to the  Registrant's  Amended  and  Restated  Articles  of
Incorporation,  Article  10.1  of the  Registrant's  By-Laws,  The  underwriting
Agreement,  the By-Laws of John Hancock  Funds,  the Adviser,  or the  Insurance
Company or  otherwise,  Registrant  has been  advised that in the opinion of the
Securities and Exchange  Commission  such  indemnification  is against policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for  indemnification  against  such  liabilities  (other than the payment by the
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by such Trustee,  officer or controlling  person in connection with the
securities  being  registered,  Registrant  will,  unless in the  opinion of its
counsel the matter has been settled by controlling precedent,  submit to a court

                                      C-4

<PAGE>

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.
