FUND INFORMATION KEY

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

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

[Clipart] Main risks The major risk factors associated with the fund.

[Clipart] Past performance The fund's total return, measured year-by-year and
over time.

[Clipart] Your expenses The overall costs borne by an investor in the fund,
including sales charges and annual expenses.
   
DURATION AND INCOME FUNDS

The concept of duration is useful in assessing the sensitivity of an income fund
to interest rate movements, which are the main source of risk for almost all
income funds. Measured in years, duration is similar to maturity but is a more
sophisticated measurement that takes into account the payback periods for the
debt securities the fund holds. A 1% rise in interest rates will generally cause
a 1% fall in value for every year of an income fund's duration.

The durations given in this prospectus are based on month-end measurements. A
fund's duration may be longer or shorter in the future.
    
JOHN HANCOCK INCOME FUNDS

These funds seek current income without sacrificing total return. Some of the
funds also invest for stability of principal. Each fund has its own strategy and
its own risk profile.

WHO MAY WANT TO INVEST

These funds may be appropriate for investors who:

o  are seeking a regular stream of income

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

o  want to diversify their portfolios

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

o  are retired or nearing retirement

Income funds may NOT be appropriate if you:

o  are investing for maximum return over a long time horizon

o  require absolute stability of your principal

RISKS OF MUTUAL FUNDS

Mutual funds are not bank deposits and are not insured or endorsed by any bank,
government agency or the FDIC. Because you could lose money by investing in
these funds, be sure to read all risk disclosure carefully before investing.

THE MANAGEMENT FIRM

All John Hancock income funds are managed by John Hancock Advisers, Inc. Founded
in 1968, John Hancock Advisers is a wholly owned subsidiary of John Hancock
Mutual Life Insurance Company and manages more than $30 billion in assets.

                                                                               3

Bond Fund

GOAL AND STRATEGY

[Clipart] The fund seeks to generate a high level of current income consistent
with prudent investment risk. In pursuing this goal, the fund normally invests
in a diversified portfolio of debt securities. These include corporate bonds,
U.S. government and agency securities and preferred securities. Most of these
securities are investment-grade, although the fund may invest up to 25% of
assets in junk bonds rated as low as CC/Ca and their unrated equivalents.

In managing its portfolio, the fund concentrates on sector allocation, industry
allocation and securities selection: deciding which types of bonds and
industries to emphasize at a given time, and then which individual bonds to buy.
When making its sector and industry allocations, the fund tries to anticipate
shifts in the business cycle, using top-down analysis to determine which sectors
and industries may benefit over the next 12 months.

In choosing individual securities, the fund uses bottom-up research to find
securities that appear comparatively undervalued. The fund looks at bonds of all
different quality levels and maturities from many different issuers, potentially
including foreign governments and corporations.

The fund intends to keep its exposure to interest rate movements generally in
line with that of the markets it invests in. The fund may use certain
derivatives (contracts whose value is based on indices or other securities),
especially in managing its exposure to interest rate risk, although it does not
intend to use them extensively.

In abnormal market conditions, the fund may temporarily invest more than 35% of
assets in investment-grade short-term securities. In these cases, the fund might
not achieve its goal.

PAST PERFORMANCE
   
[Clipart] The graph shows how the fund's total return has varied from year to
year, while the table shows performance over time (along with a broad-based
market index for reference). This information may help provide an indication of
the fund's risks and potential rewards. The average annual figures reflect sales
charges; the year-by-year figures do not, and would be lower if they did. All
figures assume dividend reinvestment. Past performance does not indicate future
results.

MAIN RISKS
   
[Clipart] The major factors in this fund's performance are interest rates and
credit risk. When interest rates rise, bond prices fall; the higher the fund's
duration, the more sensitive it is to this risk. For the 12 months ended
8/31/98, the fund's duration ranged from approximately 5.1 to 5.7 years.
    
The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. In general, lower-rated bonds have higher credit risks. If
certain sectors or investments don't perform as the fund expects, it could
underperform its peers or lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

o  Junk bonds and foreign securities may make the fund more sensitive to market
   or economic shifts in the U.S. and abroad.

o  If interest rate movements cause the fund's mortgage-related and callable
   securities to be paid off substantially earlier or later than expected, the
   fund's share price or yield could be hurt.

o  In a down market, higher-risk securities and derivatives could become harder
   to value or to sell at a fair price.

o  Certain derivatives could produce disproportionate gains or losses.

Any U.S. government guarantees on portfolio securities do not apply to these
securities' market value or current yield, or to fund shares.
   
The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

Government Income Fund

GOAL AND STRATEGY

[Clipart] The fund seeks a high level of current income consistent with
preservation of capital. Maintaining a stable share price is a secondary goal.
In pursuing these goals, the fund normally invests at least 80% of assets in
U.S. government and agency securities.
   
The fund may invest in higher-risk securities, including dollar-denominated
foreign government securities and asset-backed securities. It may also invest up
to 10% of assets in foreign governmental high-yield securities (junk bonds)
rated as low as B and their unrated equivalents.

In managing its portfolio, the fund considers interest rate trends to determine
which types of bonds to emphasize at a given time. The fund typically favors
mortgage-related securities when it anticipates that interest rates will be
relatively stable, and favors U.S. Treasuries at other times. Because high-yield
bonds often respond to market movements differently from US government bonds,
the fund may use them to manage volatility.

The fund intends to keep its exposure to interest rate movements generally in
line with that of the markets it invests in. The fund may use certain
derivatives (contracts whose value is based on indices or other securities),
especially in managing its exposure to interest rate risk, although it does not
intend to use them extensively.

In abnormal market conditions, the fund may temporarily invest more than 20% of
assets in high-quality short-term securities. In these cases, the fund might not
achieve its goal.

MAIN RISKS
   
[Clipart] The major factor in this fund's performance is interest rates. When
interest rates rise, bond prices fall; the higher the fund's duration, the more
sensitive it is to this risk. For the 12 months ended 8/31/98, the fund's
duration ranged from approximately 5.3 to 6.1 years. A fall in worldwide demand
for U.S. government securities could also lower the prices of these securities.
    
The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. In general, lower-rated bonds have higher credit risks. If
certain sectors or investments don't perform as the fund expects, it could
underperform its peers or lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

High Yield Bond Fund

GOAL AND STRATEGY

[Clipart] The fund seeks to maximize current income without assuming undue risk.
Capital appreciation is a secondary goal. In pursuing these goals, the fund
normally invests at least 65% of assets in U.S. and foreign bonds rated BBB/Baa
or lower and their unrated equivalents. The fund may invest up to 30% of assets
in junk bonds rated CC/Ca and their unrated equivalents.

In managing its portfolio, the fund concentrates on industry allocation and
securities selection: deciding which types of industries to emphasize at a given
time, and then which individual bonds to buy. The fund uses top-down analysis to
determine which industries may benefit from current and future changes in the
economy.

In choosing individual securities, the fund uses bottom-up research to find
securities that appear comparatively undervalued. The fund looks at the
financial condition of the issuers as well as the collateralization and other
features of the securities themselves.

The fund also looks at companies' financing cycles to determine which types of
securities (for example, bonds, preferred stocks or common stocks) to favor. The
fund typically invests in a broad range of industries, although it may invest up
to 40% of assets in electric utilities and telecommunications companies.

The fund may use certain higher-risk investments, including derivatives
(contracts whose value is based on indices or other securities) and restricted
or illiquid securities, and may invest up to 20% of net assets in U.S. and
foreign stocks.

In abnormal market conditions, the fund may temporarily invest more than 35% of
assets in investment-grade short-term securities. In these cases, the fund might
not achieve its goal.

MAIN RISKS
   
[Clipart] The major factors in this fund's performance are interest rates and
credit risk. When interest rates rise, bond prices fall; the higher the fund's
duration, the more sensitive it is to this risk. For the 12 months ended
8/31/98, the fund's duration ranged from approximately 3.6 to 4.5 years.

Credit risk depends largely on the perceived financial health of bond issuers.
In general, lower-rated bonds have higher credit risks. Junk bond prices can
fall on bad news about the economy, an industry or a company. Share price, yield
and total return may fluctuate more than with less aggressive bond funds.

The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. If certain industries or investments don't perform as the
fund expects, it could underperform its peers or lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

o  Foreign investments carry additional risks, including potentially unfavorable
   currency exchange rates, inadequate or inaccurate financial information and
   social or political upheavals.

o  If interest rate movements cause the fund's callable securities to be paid
   off substantially earlier or later than expected, the fund's share price or
   yield could be hurt.

o  If the fund concentrates its investments in telecommunications or electric
   utilities, its performance could be tied more closely to those industries
   than to the market as a whole.

o  In a down market, higher-risk securities and derivatives could become harder
   to value or to sell at a fair price.

o  Certain derivatives could produce disproportionate gains or losses.

The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

Intermediate Maturity Government Fund

GOAL AND STRATEGY
   
[Clipart] The fund seeks a high level of current income consistent with
preservation of capital and maintenance of liquidity. In pursuing this goal, the
fund normally invests at least 80% of assets in U.S. government and agency
securities. Although the fund may invest in bonds of any maturity, it maintains
a dollar-weighted average maturity of between three and ten years. The fund
generally keeps its overall duration between two and five years.
    
In managing its portfolio, the fund considers interest rate trends to determine
which types of bonds to emphasize at a given time. The fund typically favors
mortgage-related securities when it anticipates that interest rates will be
relatively stable, and favors U.S. Treasuries at other times. The fund also
invests in non-Treasury securities to enhance its current yields.

The fund may use certain derivatives (contracts whose value is based on indices
or other securities), especially in managing its exposure to interest rate risk.
It may also invest up to 20% of assets in asset-backed or corporate debt
securities in the highest credit category (those rated AAA/Aaa and their unrated
equivalents). However, it does not intend to use any of these investments
extensively.

In abnormal market conditions, the fund may temporarily invest more than 20% of
assets in high-quality short-term securities. In these cases, the fund might not
achieve its goal.

sensitive it is to this risk. For the 12 months ended 8/31/98, the fund's

The fund could lose money if any bonds it owns are downgraded in credit rating

Strategic Income Fund

GOAL AND STRATEGY
   
[Clipart] The fund seeks a high level of current income. In pursuing this goal,
the fund invests primarily in the following types of securities:

o  foreign government and corporate debt securities from developed and emerging
   markets

o  U.S. government and agency securities

o  U.S. junk bonds rated as low as CC/Ca and their unrated equivalents

The fund generally intends to keep its average credit quality in the
investment-grade range.

In managing its portfolio, the fund uses top-down analysis to allocate assets
among the three major sectors mentioned above. Although it could invest all
assets in one sector, it generally expects to remain diversified among all
three.

Within the foreign sector, the fund uses a combination of bottom-up research and
macroeconomic analysis to select individual securities from a range of regions,
countries and industries. These securities may be rated as low as CC/Ca and
their unrated equivalents.

Within the U.S. government sector, the fund selects investments primarily for
current yield and total return.

Within the junk bond sector, the fund uses bottom-up research to select
individual securities from a wide range of industries.

The fund may use certain higher-risk investments, including derivatives
(contracts whose value is based on indices or other securities), restricted or
illiquid securities, and may invest up to 10% of net assets in U.S. or foreign
stocks.

In abnormal market conditions, the fund may temporarily invest extensively in
investment-grade short- term securities. In these cases, the fund might not
achieve its goal.

MAIN RISKS
   
[Clipart] The fund's risk profile depends on its sector allocation. In general,
investors should expect fluctuations in share price, yield and total return that
are above average for bond funds.

When interest rates rise, bond prices fall; the higher the fund's duration, the
more sensitive it is to this risk. For the 12 months ended 8/31/98, the fund's
duration ranged from approximately 4.6 to 6.4 years.

A fall in worldwide demand for U.S. government securities could lower the prices
of these securities. The fund could lose money if any bonds it owns are
downgraded in credit rating or go into default. In general, lower-rated bonds
have higher credit risks, and their prices can fall on bad news about the
economy, an industry or a company. If certain allocation strategies or certain
industries or investments don't perform as the fund expects, it could
underperform its peers or lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

o  Foreign investments carry additional risks, including potentially unfavorable
   currency exchange rates, inadequate or inaccurate financial information and
   social or political upheavals. These risks are greater in emerging markets.

o  If interest rate movements cause the fund's callable securities to be paid
   off substantially earlier or later than expected, the fund's share price or
   yield could be hurt.

o  In a down market, higher-risk securities and derivatives could become harder
   to value or to sell at a fair price.

o  Certain derivatives could produce disproportionate gains or losses.

Any governmental guarantees on portfolio securities do not apply to these
securities' market value or current yield, or to fund shares.

The fund may trade securities actively, which could increase its transaction
costs (thus lowering performance) and increase your taxable dividends.

YOUR EXPENSES
   
[Clipart] Transaction expenses are charged directly to your account. Operating
expenses are paid from the fund's assets, and therefore are paid by shareholders
indirectly.

CHOOSING A SHARE CLASS

Each share class has its own cost structure, allowing you to choose the one that
best meets your requirements. Your financial representative can help you decide.

- --------------------------------------------------------------------------------
 Class A
- --------------------------------------------------------------------------------

o  Front-end sales charges, as described at right.
   
o  Distribution and service (12b-1) fees of 0.25% (0.30% for Bond and Strategic
   Income).
    
- --------------------------------------------------------------------------------
 Class B
- --------------------------------------------------------------------------------

o  No front-end sales charge; all your money goes to work for you right away.

o  Distribution and service (12b-1) fees of 1.00%.

o  A deferred sales charge, as described on following page.

o  Automatic conversion to Class A shares after either five years (Intermediate
   Maturity Government) or eight years (all other funds), thus reducing future
   annual expenses.

- --------------------------------------------------------------------------------
 Class C
- --------------------------------------------------------------------------------

Currently available only on Bond, High Yield Bond and Strategic Income.

o  No front-end sales charge; all your money goes to work for you right away.

o  Distribution and service (12b-1) fees of 1.00%.

o  A 1.00% contingent deferred sales charge on shares sold within one year of
   purchase.

o  No automatic conversion to Class A shares, so annual expenses continue at the
   Class C level throughout the life of your investment.


For actual past expenses of each share class, see the fund-by-fund information
earlier in this prospectus.

Because 12b-1 fees are paid on an ongoing basis, Class B and Class C
shareholders could end up paying more expenses over the long term than if they
had paid a sales charge.

- --------------------------------------------------------------------------------
HOW SALES CHARGES ARE CALCULATED

Class A Sales charges are as follows:

 $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:

- --------------------------------------------------------------------------------
 CDSC on $1 million+ investments - all funds
- --------------------------------------------------------------------------------
 Your investment                            CDSC on shares

 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 and 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) on shares you sell within a certain time after you
bought them, as described in the tables below. There is no CDSC on shares
acquired through reinvestment of dividends. The CDSC is based on the original
purchase cost or the current market value of the shares being sold, whichever is
less. The CDSCs are as follows:

 After 1 year                            none

For purposes of these CDSCs, all purchases made during a calendar month are
counted as having been made on the first day of that month.

CDSC calculations are based on the number of shares involved, not on the value
of your account. To keep your CDSC as low as possible, each time you place a
request to sell shares we will first sell any shares in your account that carry
no CDSC. If there are not enough of these to meet your request, we will sell
those shares that have the lowest CDSC.

- --------------------------------------------------------------------------------
SALES CHARGE REDUCTIONS AND WAIVERS

Reducing your Class A sales charges  There are several ways you can combine
multiple purchases of Class A shares of John Hancock funds to take advantage of
the breakpoints in the sales charge schedule. The first three ways can be
combined in any manner.

o  Accumulation Privilege -- lets you add the value of any Class A shares you
   already own to the amount of your next Class A investment for purposes of
   calculating the sales charge. Retirement plans investing $1 million in Class
   B shares may add that value to Class A purchases to calculate charges.

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, or consult the SAI (see the
back cover of this prospectus).

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

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

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

o  to purchase a John Hancock Declaration annuity

To utilize: if you think you may be eligible for a CDSC waiver, contact your
financial representative or Signature Services, or consult the SAI (see the back
cover of this prospectus).

                                                                 YOUR ACCOUNT 15
<PAGE>

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.

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

o  selling brokers and their employees and sales representatives

o  financial representatives utilizing fund shares in fee-based investment
   products under signed 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  certain insurance company contract holders (one-year CDSC usually applies)

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

To utilize: if you think you may be eligible for a sales charge waiver, contact
Signature Services or consult the SAI (see the back cover of this prospectus).

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

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

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

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

You will need to obtain your signature guarantee from a member of the Signature
Guarantee Medallion Program. Most brokers and securities dealers are members of
this program. A notary public CANNOT provide a signature guarantee.

TRANSACTION POLICIES

Valuation of shares  The net asset value per share (NAV) for each fund and class
is determined each business day at the close of regular trading on the New York
Stock Exchange (typically 4 P.M. Eastern Time). The funds use market prices in
valuing portfolio securities, but may use fair-value estimates if reliable
market prices are unavailable.

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. Also for your protection, telephone
transactions are not permitted on accounts whose names or addresses have changed
within the past 30 days. Proceeds from telephone transactions can only be mailed
to the address of record.

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

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

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

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

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

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

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

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

o  in all other circumstances, every quarter

Every year you should also receive, if applicable, a Form 1099 tax information
statement, mailed by January 31.
   
Dividends  The funds generally declare dividends daily and pay them monthly.
Capital gains, if any, are distributed annually, typically after the end of a
fund's fiscal year. Most of these funds' dividends are income dividends. Your
dividends begin accruing the day after payment is received by the fund and
continue through the day your shares are actually sold.
    
Dividend reinvestments  Most investors have their dividends reinvested in
additional shares of the same fund and class. If you choose this option, or if
you do not indicate any choice, your dividends will be reinvested on the
dividend record date. Alternatively, you can choose to have a check for your
dividends mailed to you. However, if the check is not deliverable, your
dividends will be reinvested.

20  YOUR ACCOUNT
<PAGE>

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

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

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

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

Year 2000 compliance  The adviser and the funds' service providers are taking
steps to address any year 2000-related computer problems. However, there is some
risk that these problems could disrupt the funds' operations or financial
markets generally.

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

BUSINESS STRUCTURE

The diagram below shows the basic business structure used by the John Hancock
income funds. Each fund's board of trustees oversees the fund's business
activities and retains the services of the various firms that carry out the
fund's operations.

The trustees of the Government Income, High Yield Bond and Intermediate Maturity
Government funds have the power to change these funds' respective investment
goals without shareholder approval.

Management fees  The management fees paid to the investment adviser by the John
Hancock income funds last year are as follows:
   
- --------------------------------------------------------------------------------
 Fund                                      % of net assets

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 the laws of The  Commonwealth
of Massachusetts.  Prior to December 22, 1994, the Fund was called  Transamerica
High Yield Bond Fund.  Prior to August 30,  1996,  the Fund was a series of John
Hancock Series, Inc., a Maryland corporation.

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

INVESTMENT OBJECTIVE AND POLICIES

The following  information  supplements the discussion of the Fund's  investment
objective and policies discussed in the Prospectus.  Appendix A contains further
information describing investment risks. The investment objective of the Fund is
non-fundamental. There is no assurance that the Fund will achieve its investment
objective.

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

Under normal market  conditions,  at least 65% of the Fund's total assets may be
invested in bonds or  debentures  rated  "Baa" or lower by Moody's,  or "BBB" or
lower by S&P;  however,  no more  than 30% of the  Fund's  total  assets  may be
invested in securities  that are rated as low as "CC" by S&P or "Ca" by Moody's.
Unrated  securities  will also be considered for investment by the Fund when the
Adviser  believes  that the  issuer's  financial  condition,  or the  protection
afforded by the terms of the securities themselves,  limits the risk to the Fund
to a degree  comparable to that of rated  securities  consistent with the Fund's
objectives and policies.

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

Although the Fund intends to maintain  investment emphasis on debt securities of
domestic issuers,  the Fund may invest without  limitation in debt securities of
foreign issuers,  including those issued by  supranational  entities such as the
World Bank. The Fund may also purchase debt securities  issued in an any country

                                       2
<PAGE>

developed   or   undeveloped.   Investments   in   securities   of   issuers  in
non-industrialized  countries  generally involve more risk and may be considered
speculative.  The Fund may also enter into  forward  foreign  currency  exchange
contracts for the purchase or sale of foreign currency for hedging purposes. The
risks of foreign investments should be carefully considered by investors.

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

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

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

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

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

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

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

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

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

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

         3.  investment grade short-term notes;

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

         5. related repurchase agreements.

                                       3
<PAGE>
                                      
Government Securities. The Fund may invest in U.S. Government securities,  which
are  obligations  issued or guaranteed by the U.S.  Government and its agencies,
authorities or instrumentalities.  Certain U.S. Government securities, including
U.S.  Treasury  bills,  notes  and  bonds,  and  Government   National  Mortgage
Association  certificates  ("Ginnie Maes"),  are supported by the full faith and
credit of the United States. Certain other U.S. Government securities, issued or
guaranteed by Federal  agencies or  government  sponsored  enterprises,  are not
supported  by the  full  faith  and  credit  of the  United  States,  but may be
supported  by the right of the issuer to borrow  from the U.S.  Treasury.  These
securities  include  obligations  of the Federal Home Loan Mortgage  Corporation
("Freddie   Macs"),   and   obligations   supported   by  the   credit   of  the
instrumentality,  such as Federal National  Mortgage  Association Bonds ("Fannie
Maes").

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

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

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

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

Municipal  Bonds.  Municipal bonds are issued to obtain funds for various public
purposes including the construction of a wide range of public facilities such as
airports,  highways, bridges, schools, hospitals,  housing, mass transportation,
streets and water and sewer  works.  Other public  purposes for which  municipal
bonds may be issued include refunding outstanding  obligations,  obtaining funds
for general  operating  expenses  and  obtaining  funds to lend to other  public
institutions   and  facilities.   In  addition,   certain  types  of  industrial
development  bonds are  issued by or on behalf of public  authorities  to obtain

                                       4
<PAGE>

funds  for  many  types of  local,  privately  operated  facilities.  Such  debt
instruments are considered municipal obligations if the interest paid on them is
exempt from federal income tax. The payment of principal and interest by issuers
of certain  obligations  purchased by the Fund may be  guaranteed by a letter of
credit, note repurchase agreement,  insurance or other credit facility agreement
offered  by a bank or  other  financial  institution.  Such  guarantees  and the
creditworthiness  of guarantors will be considered by the Adviser in determining
whether a municipal obligation meets the Fund's investment quality requirements.
No  assurance  can be given that a  municipality  or  guarantor  will be able to
satisfy the payment of principal or interest on a municipal obligation.

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

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

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

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

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

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

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

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

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

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

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

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

                                       6
<PAGE>

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

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

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

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

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

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

                                       7
<PAGE>

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

Planned  amortization  class ("PAC") and target  amortization  class ("TAC") CMO
bonds involve less exposure to prepayment, extension and interest rate risk than
other Mortgage-Backed  Securities,  provided that prepayment rates remain within
expected  prepayment  ranges or "collars." To the extent that  prepayment  rates
remain within these prepayment  ranges,  the residual or support tranches of PAC
and TAC CMOs  assume the extra  prepayment,  extension  and  interest  rate risk
associated with the underlying mortgage assets.

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

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

Mortgage  "Dollar Roll"  Transactions.  The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers  pursuant to which the
Fund sells Mortgage-Backed Securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date.  The Fund will only enter into covered rolls. A "covered roll" is a
specific type of dollar roll for which there is an offsetting cash position or a
cash  equivalent  security  position  which  matures  on or before  the  forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior  security and will be excluded from the  calculation
of the Fund's borrowing and other senior securities. For financial reporting and
tax  purposes,   the  Fund  treats   mortgage   dollar  rolls  as  two  separate
transactions;   one  involving  the  purchase  of  a  security  and  a  separate
transaction  involving a sale. The Fund does not currently  intend to enter into
mortgage rolls that are accounted for as financing.

Pay-In-Kind,  Delayed and Zero Coupon Bonds. The Fund may invest in pay-in-kind,
delayed and zero coupon bonds.  These are  securities  issued at a discount from
their face  value  because  interest  payments  are  typically  postponed  until
maturity.  The amount of the discount rate varies depending on factors including
the time remaining until  maturity,  prevailing  interest rates,  the security's
liquidity and the issuer's  credit quality.  These  securities also may take the
form of debt  securities that have been stripped of their interest  payments.  A
portion of the discount with respect to stripped tax-exempt  securities or their
coupons  may be  taxable.  The market  prices of  pay-in-kind,  delayed and zero
coupon  bonds   generally   are  more   volatile   than  the  market  prices  of
interest-bearing  securities  and are likely to  respond to a greater  degree to
changes  in  interest  rates than  interest-bearing  securities  having  similar
maturities and credit quality.  The Fund's  investments in pay-in-kind,  delayed
and zero  coupon  bonds may require  the Fund to sell  certain of its  portfolio
securities to generate  sufficient cash to satisfy  certain income  distribution
requirements.  See "Tax Status." At times when the Fund invests in  pay-in-kind,
delayed and zero coupon bonds, it will not be pursuing its primary  objective of
maximizing current income.

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

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

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

Swap agreements will tend to shift the Fund's investment  exposure from one type
of investment to another.  For example,  if the Fund agreed to exchange payments
in dollars for payments in a foreign currency,  the swap agreement would tend to
decrease the Fund's exposure to U.S. interest rates and increase its exposure to
foreign  currency and interest rates.  Caps and floors have an effect similar to
buying or writing  options.  Depending on how they are used, swap agreements may
increase or decrease the overall  volatility of the Fund's  investments  and its
share price and yield.
                                       9

Swap agreements are sophisticated  hedging  instruments that typically involve a
small  investment  of cash  relative to the  magnitude  of risks  assumed.  As a
result,  swaps can be highly volatile and may have a considerable  impact on the
Fund's  performance.  Swap  agreements  are  subject  to  risks  related  to the
counterparty's   ability  to   perform,   and  may   decline  in  value  if  the
counterparty's creditworthiness deteriorates. The Fund may also suffer losses if
it is unable to terminate  outstanding  swap  agreements  or reduce its exposure
through offsetting transactions.  The Fund will maintain in a segregated account
with its custodian,  cash or liquid  securities equal to the net amount, if any,
of the excess of the Fund's  obligations over its  entitlements  with respect to
swap, cap, collar or floor transactions.

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

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

Credit  card  receivables  are  generally  unsecured  and  the  debtors  on such
receivables  are  entitled  to the  protection  of a number of state and federal
consumer  credit  laws,  many of which  give such  debtors  the right to set-off
certain  amounts  owed on the credit  cards,  thereby  reducing the balance due.
Automobile  receivables  generally are secured,  but by automobiles  rather than
residential  real property.  Most issuers of automobile  receivables  permit the
loan  servicers  to retain  possession  of the  underlying  obligations.  If the
servicer were to sell these  obligations to another party,  there is a risk that
the purchaser  would acquire an interest  superior to that of the holders of the
asset-backed  securities.  In addition,  because of the large number of vehicles
involved in a typical issuance and technical  requirements under state laws, the
trustee  for the  holders of the  automobile  receivables  may not have a proper
security  interest  in  the  underlying  automobiles.  Therefore,  there  is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

Lower Rated High Yield Debt  Obligations.  The Fund may invest in high yielding,
fixed income  securities rated below investment grade (e.g.,  rated below Baa by
Moody's or below BBB by S&P),  sometimes referred to as junk bonds.  Ratings are
based largely on the historical financial condition of the issuer. Consequently,
the rating  assigned to any particular  security is not necessarily a reflection
of the issuer's current financial  condition,  which may be better or worse than
the rating would indicate.

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

                                       10
<PAGE>

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

The market price and liquidity of lower rated fixed income securities  generally
respond to short term corporate and market developments to a greater extent than
do the price and liquidity of higher rated securities  because such developments
are perceived to have a more direct  relationship to the ability of an issuer of
such lower rated securities to meet its ongoing debt obligations.

Reduced  volume  and  liquidity  in the high yield  bond  market or the  reduced
availability of market  quotations will make it more difficult to dispose of the
bonds and to value  accurately the Fund's assets.  The reduced  availability  of
reliable,  objective  data may  increase  the Fund's  reliance  on  management's
judgment in valuing high yield bonds.  In addition,  the Fund's  investments  in
high yield  securities  may be  susceptible  to adverse  publicity  and investor
perceptions,  whether  or not  justified  by  fundamental  factors.  The  Fund's
investments, and consequently its net asset value, will be subject to the market
fluctuations and risks inherent in all securities.

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

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

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

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

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

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

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

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

Because foreign  securities may be denominated in currencies other than the U.S.
dollar,  changes in foreign  currency  exchange rates will affect the Fund's net
asset  value,  the value of  dividends  and  interest  earned,  gains and losses
realized on the sale of securities, and any net investment income and gains that
the Fund distributes to shareholders. Securities transactions undertaken in some
foreign markets may not be settled promptly,  so that the Fund's  investments on
foreign  exchanges  may be less  liquid and  subject to the risk of  fluctuating
currency exchange rates pending settlement.

Foreign  securities  will be purchased  in the best  available  market,  whether
through  over-the-counter  markets or exchanges  located in the countries  where
principal  offices of the issuers are located.  Foreign  securities  markets are
generally  not as developed or  efficient as those in the United  States.  While
growing in volume, they usually have substantially less volume than the New York

                                       12
<PAGE>

Stock Exchange,  and securities of some foreign issuers are less liquid and more
volatile than securities of comparable United States issuers.  Fixed commissions
on foreign exchanges are generally higher than negotiated  commissions on United
States exchanges,  although the Fund will endeavor to achieve the most favorable
net results on its portfolio  transactions.  There is generally less  government
supervision and regulation of securities  exchanges,  brokers and listed issuers
than in the United States.

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

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

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

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

Reverse Repurchase  Agreements.  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.  The Fund will also continue to
be subject to the risk of a decline in the market value of the  securities  sold
under the agreements  because it will reacquire those  securities upon effecting
their repurchase.  To minimize various risks associated with reverse  repurchase
agreements,  the Fund will  establish 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 not enter into reverse repurchase agreements and
other  borrowings  exceeding  in the  aggregate  more than 33 1/3% of the market
value  of its  total  assets.  The  Fund  will  enter  into  reverse  repurchase
agreements  only with federally  insured banks or savings and loan  associations

                                       13
<PAGE>

which are  approved  in advance as being  creditworthy  by the  Trustees.  Under
procedures   established   by  the  Trustees,   the  Adviser  will  monitor  the
creditworthiness of the banks involved.

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

                                       14
<PAGE>

cover call  options  on a  securities  index by owning  securities  whose  price
changes are expected to be similar to those of the underlying index.

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

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

                                       15
<PAGE>

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

                                       16
<PAGE>

securities  through  the sale of  futures  contracts.  When  interest  rates are
falling or  securities  prices are rising,  the Fund,  through  the  purchase of
futures contracts, can attempt to secure better rates or prices than might later
be available in the market when it effects anticipated  purchases.  The Fund may
seek to  offset  anticipated  changes  in the value of a  currency  in which its
portfolio securities,  or securities that it intends to purchase,  are quoted or
denominated by purchasing and selling futures contracts on such currencies.

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

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

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

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

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

The writing of a call option on a futures contract generates a premium which may
partially offset a decline in the value of the Fund's assets.  By writing a call
option, the Fund becomes  obligated,  in exchange for the premium (upon exercise
of the option) to sell a futures contract if the option is exercised,  which may

                                       17
<PAGE>

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 a 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 of the Fund denominated in the related currency in
the cash market at the time when the  futures or option  position is closed out.
However, in particular cases, when it is economically  advantageous for 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.

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 a segregated  account  consisting  of cash or liquid  securities in an
amount equal to the underlying value of such contracts and options.

While  transactions  in futures  contracts  and  options  on futures  may reduce
certain risks,  these  transactions  themselves  entail certain other risks. For
example,  unanticipated  changes  in  interest  rates or  securities  prices  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. 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.

                                       18
<PAGE>

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 markets
funds.  When the  Fund  lends  portfolio  securities,  there is a risk  that the
borrower may fail to return the  securities  involved in the  transaction.  As a
result, the Fund may incur a loss or, in the event of the borrower's bankruptcy,
the Fund may be delayed in or prevented from liquidating the collateral. It is a
fundamental  policy of the Fund not to lend portfolio  securities having a total
value exceeding 30% of its total assets.

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

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

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

On the date the Fund enters into an agreement to purchase  securities on a when-
issued or  forward  commitment  basis,  the Fund will  segregate  in a  separate
account cash or liquid  securities,  of any type or maturity,  equal in value to

                                       19
<PAGE>

the  Fund's  commitment.  These  assets  will be  valued  daily at  market,  and
additional  cash or securities  will be segregated in a separate  account to the
extent  that the total  value of the assets in the  account  declines  below the
amount of the when-issued  commitments.  Alternatively,  the Fund may enter into
offsetting contracts for the forward sale of other securities that it owns.

Short-Term Trading and Portfolio Turnover. Short-term trading means the purchase
and subsequent sale of a security after it has been held for a relatively  brief
period of time.  The Fund may engage in short-term  trading in response to stock
market  conditions,  changes  in  interest  rates or other  economic  trends and
developments,  or to take advantage of yield  disparities  between various fixed
income  securities  in  order  to  realize  capital  gains  or  improve  income.
Short-term trading may have the effect of increasing  portfolio turnover rate. A
high rate of  portfolio  turnover  (100% or  greater)  involves  correspondingly
greater  brokerage  transaction  expenses and may make it more difficult for the
Fund to  qualify  as a  regulated  investment  company  for  federal  income tax
purposes. The Fund's portfolio 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  Statement of Additional  Information),  or
pledge,  mortgage or hypothecate an amount of its assets (taken at market value)
in excess of 15% of its total assets, in each case taken at the lower of cost or
market value. For the purpose of this restriction,  collateral arrangements with
respect  to  options,  futures  contracts,  options  on  futures  contracts  and
collateral  arrangements  with respect to initial and variation  margins are not
considered a pledge of assets.

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

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

                                       20
<PAGE>

(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.

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

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

(8)      Purchase or retain in its portfolio any securities  issued by an issuer
any of whose officers,  directors, trustees or security holders is an officer or
Trustee of such  Fund,  or is a member,  partner,  officer  or  Director  of the
Adviser,  if after the purchase of the securities of such issuer by 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.

(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  (the  "Investment  Company  Act")  if  such  issuance  is
specifically  prohibited  by  the  Investment  Company  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.

                                       21
<PAGE>

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

(14)     Purchase  securities  of any issuer  (other than  securities  issued or
guaranteed by the U.S. Government or its agencies or  instrumentalities) if such
purchase, at the time thereof, would cause the Fund to hold more than 10% of any
class of securities of such issuer.  For this purpose,  all  indebtedness  of an
issuer shall be deemed a single class and all preferred stock of an issuer shall
be deemed a single class.

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

(1)      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  of the  Fund's
portfolio securities,  in the securities of open-end investment companies or (b)
the purchase of shares of any  investment  company in connection  with a merger,
consolidation,  reorganization or purchase of substantially all of the assets of
another investment  company.  Subject to the above percentage  limitations,  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 or rating  restriction on investment or utilization
of assets  is  adhered  to at the time an  investment  is made or assets  are so
utilized,  a later change in percentage  resulting  from changes in the value of
the Fund's  portfolio  securities or a later change in the rating of a portfolio
security will not be considered a violation of policy.

                                       22

INVESTMENT ADVISORY AND OTHER SERVICES

The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts 02199-7603,
was  organized in 1968 and has more than $30 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

Best.  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 Agreements,  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.
                                       32
<PAGE>

   
The Fund bears all cost of its  organization  and  operation,  including but not
limited to  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 custodian  including  those for keeping books and accounts,
maintaining a committed line of credit,  and  calculating the net asset value of
shares;  fees and expenses of transfer  agents and dividend  disbursing  agents;
legal, accounting,  financial, management, tax and auditing fees and expenses of
the Fund (including and allocable portion of the cost of the Adviser's employees
rendering such services to the Fund);  the compensation and expenses of Trustees
who are not  otherwise  affiliated  with the Trust,  the Adviser or any of their
affiliates;  expenses of Trustees' and shareholders'  meeting; trade association
memberships; insurance premiums; and any extraordinary expenses.
    

As compensation  for its services under the Advisory  Agreements,  the Fund pays
the  Adviser  monthly a fee based on a stated  percentage  of the average of the
daily net assets of the Fund as follows:
                                                                      Fee
Average Daily Net Assets                                         (Annual Rate)
- ------------------------                                         -------------

First $75 million                                                   0.625%
Next $75 million                                                    0.5625%
Over $150 million                                                   0.500%

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

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

                                       33
<PAGE>

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

The Advisory fees payable by the Fund to the Adviser, were as follows:

   

         12/22/94-10/31/95                                        $  897,349
         11/1/95-10/31/96                                         $1,326,701
         11/1/96-5/31/97                                          $1,204,001
         6/1/97-5/31/98                                           $3,997,329
    

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

The amount of $13,697 for the Fund reflects the total of administrative services
fees paid to the Adviser for the fiscal year ended October 31, 1995.

   
Accounting and Legal  Services  Agreement.  The Trust,  on behalf the Fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this agreement,  the Adviser  provides the Fund with certain tax,  accounting
and legal  services.  For the fiscal year ended October 31, 1996,  The Fund paid
the  Adviser  $37,927 for  services  under this  agreement.  For the period from
November 1, 1996 to May 31, 1997, the Fund paid the Adviser $42,106 for services
under this agreement.  For the fiscal year ended May 31, 1998, the Fund paid the
Adviser $136,741 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.

shares;  and (iii)  with  respect to Class B and Class C shares  only,  interest
expenses on unreimbursed distribution expenses. The service fees will by used to
compensate  Selling  Brokers  and  others for  providing  personal  and  account
maintenance  services to  shareholders.  In the event that John Hancock Funds is
not fully  reimbursed  for  payments or expenses  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 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 May 31, 1998 an
aggregate of  $13,113,933 of  distribution  expenses or 2.23% of the average net
assets of the Fund's  Class B shares was not  reimbursed  or  recovered  by John
Hancock Funds through the receipt of deferred  sales charges or Rules 12b-1 fees
in prior periods.  Class C shares of the Fund did not commence  operations until
May 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.  Each of the Plans further provides that it may not be amended to
increase  the  maximum  amount of the fees for the  services  described  therein
without the approval of a majority of the outstanding shares of the class of the
Fund which has voting  rights to that Plan.  Each of the Plans  provide  that no
material amendment to the Plan will be effective unless it is approved by a vote
of a majority of the  Trustees  and the  Independent  Trustees of the Fund.  The
holders of Class A, 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, these is a reasonable
likelihood  that the Plans will benefit the holders of the  applicable  class of
shares of the Fund.

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

During the fiscal year ended May 31, 1998,  the Fund paid John Hancock Funds the
following amounts of expenses in connection with their services.  Class C shares
of the Fund did not commence operations until May 1, 1998; therefore,  there are
no expenses to report.

SALES COMPENSATION

As part of their business strategies, each of the John Hancock 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.  The sales charges and 12b-1
fees paid by investors are detailed in the  prospectus  and under  "Distribution
Contracts" in this  Statement of Additional  Information.  The portions of these
expenses  that are reallowed to financial  services  firms are shown on the next
page.
    

       

Whenever  you make an  investment  in the  Fund,  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.  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.

(1)   Reallowance/commission   percentages   and  service  fee  percentages  are

CDSC  revenues  collected by John Hancock  Funds may be used to pay  commissions
when there is no initial sales charge.

NET ASSET VALUE

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

                                       38
<PAGE>

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

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

The NAV for each class of the Fund is determined  each business day at the close
of regular trading on the New York Stock Exchange  (typically 4:00 p.m.  Eastern
Time) by dividing a class net assets by the number of its shares outstanding. On
any day an  international  market is closed and the New York Stock  Exchange  is
open,  any foreign  securities  will be valued at the prior day's close with the
current day's  exchange  rate.  Trading of foreign  securities may take place on
Saturdays and U.S.  business holidays on which 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 only
will be issued for full  shares.  The  Trustees of the Fund reserve the right to
change or waive the Fund's  minimum  investment  requirements  and to reject any
order to purchase shares  (including  purchase by exchange) when in the judgment
of the Adviser such rejection is in the Fund's best interest.

The sales  charges  applicable  to  purchases  of 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,  the investor is
entitled to accumulate  current  purchases with the greater of the current value
(at offering price) of the Class A shares of the Fund, owned by the investor, or
if John Hancock Signature Services,  Inc. ("Signature  Services") is notified by
the investor's  dealer or the investor at the time of the purchase,  the cost of
the Class A shares owned.

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

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

                                       39
<PAGE>

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

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

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

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

o        Retirement plans investing through the PruArray Program sponsored by
         Prudential Securities.

   
o        Pension plans transferring  assets from a John Hancock variable annuity
         contract to the Fund pursuant to an exemptive  application  approved by
         the Securities Exchange Commission.
    

o        Existing  full  service  clients  of the Life  Company  who were  group
         annuity  contract  holders as of  September  1, 1994,  and  participant
         directed  retirement plans with at least 100 eligible  employees at the
         inception of the Fund  account.  Each of these  investors  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.

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.

                                       40
<PAGE>

Accumulation Privilege.  Investors (including investors combining purchases) who
are  already  Class A  shareholders  may also  obtain the benefit of the reduced
sales charge by taking into account not only the amount being  invested but also
the investor's 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. Retirement plan investors may include the value of Class
B shares if class B shares held are greater  than $1 million.  Retirement  plans
must notify Signature Services to utilize.

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

Letter of Intention.  Reduced sales charges are also  applicable to  investments
made  pursuant  to a Letter  of  Intention  (the  "LOI"),  which  should be read
carefully  prior to its  execution by an  investor.  The Fund offers two options
regarding  the  specified  period  for  making  investments  under the LOI.  All
investors have the option of making their investments over a specified period of
thirteen (13) months. Investors who are using the Fund as a funding medium for a
retirement plan, however,  may opt to make the necessary  investments called for
by the LOI over a forty-eight (48) month period.  These retirement plans include
Traditional,  Roth and Education IRAs, SEP, SARSEP,  401(k),  403(b)  (including
TSAs),  SIMPLE IRA, SIMPLE 401(k),  Money Purchase  Pension,  Profit Sharing and
Section 457 plans.  Non-qualified  and  qualified  retirement  plan  investments
cannot be combined to satisfy an LOI of 48 months. Such an investment (including
accumulations  and  combinations  but not including  reinvested  dividends) must
aggregate $100,000 or more invested during the specified period from the date of
the LOI or from a date  within  ninety  (90) days prior  thereto,  upon  written
request to  Signature  Services.  The sales  charge  applicable  to all  amounts
invested  under the LOI is computed as if the  aggregate  amount  intended to be
invested had been invested immediately. If such aggregate amount is not actually
invested,  the difference in the sales charge actually paid and the sales charge
payable had the LOI not been in effect is due from the  investor.  However,  for
the purchases  actually made with the specified period (either 13 or 48 months),
the sales charge  applicable  will not be higher than that which would have been
applied  (including  accumulations  and  combinations)  had the LOI been for the
amount actually invested.

The LOI  authorizes  Signature  Services  to hold in escrow  sufficient  Class A
shares  (approximately  5% of the  aggregate) to make up any difference in sales
charges on the amount intended to be invested and the amount actually  invested,
until such investment is completed  within the specified  period,  at which time
the escrow shares will be released. If the total investment specified in the LOI
is not  completed,  the Class A shares  held in escrow may be  redeemed  and the
proceeds  used as required  to pay such sales  charges as may be due. By signing
the  LOI,   the   investor   authorizes   Signature   Services  to  act  as  his
attorney-in-fact  to redeem  any  escrowed  Class A shares  and adjust the sales
charge,  if  necessary.  A LOI does not  constitute a binding  commitment  by an
investor to purchase,  or by 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 an initial 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 years 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 shares are not available to full-service  retirement plans  administered
by  Signature  Services  or the Life  Company  that had more  than 100  eligible
employees at the inception of the Fund account.

The amount of the CDSC, if any, will vary  depending on the number of years from
the  time of  payment  for the  purchase  of Class B  shares  until  the time of
redemption  of such  shares.  Solely for purposes of  determining  the number of
years from the time of any payment for the  purchase of 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)
         o Minus proceeds of 10 shares not subject to CDSC
          (dividend reinvestment)                                       (120.00)
                                                                        -------
         o Amount subject to CDSC                                       $280.00

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

Proceeds  from the CDSC are paid to John Hancock  Funds and are used in whole or
in part by John  Hancock  Funds to defray  its  expenses  related  to  providing
distribution-related  services  to the Fund in  connection  with the sale of the
Class B 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 a CDSC, unless indicated otherwise, in the circumstances defined below:

For all account types:

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

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

         accounts unless trust is being dissolved.)

*        Redemptions  of Class B (but not Class C) shares  made under a periodic
         withdrawal  plan,  or  redemptions  for fees  charged  by  planners  or
         advisors for advisory  services,  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 or Class C 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

         401(a) (such as Money Purchase Pension Plans and  Profit-Sharing/401(k)
         Plans),  457 and 408 (SEPs and  SIMPLE  IRAs) of the  Internal  Revenue
         Code.

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

                                       45

SPECIAL REDEMPTIONS

Although  the Fund 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 security would be valued for the purpose of making such payment
at the same value as used in  determining  the Fund's net asset value.  The Fund
has elected to be governed by Rule 18f-1 under the Investment Company Act. Under
that rule,  the Fund must redeem  their  shares for cash except to the extent to
that the redemption  payments to any shareholder  during any 90-day period would
exceed  the  lesser of  $250,000  or 1% of the  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 the
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 from the redemption
of shares of the Fund.  Since the redemption price of the shares of the Fund may
be more or less than the shareholder's cost,  depending upon the market value of
the securities owned by the Fund at the time of redemption,  the distribution of
cash  pursuant  to this  plan  may  result  in  realization  of gain or loss for
purposes  of  Federal,  state and  local  income  taxes.  The  maintenance  of a
Systematic  Withdrawal Plan  concurrently with purchases of additional shares of

                                       46
<PAGE>

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
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 order date of any investment.
    

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

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

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

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

Retirement plans participating in Merrill Lynch's servicing programs:

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

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

DESCRIPTION OF THE FUND'S SHARES

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

The shares of each class of the Fund represent an equal  proportionate  interest
in the aggregate net assets  attributable to the classes 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  the
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.
Fund  shareholders  may  remove a Trustee  by the  affirmative  vote of at least
two-thirds of the Trust's  outstanding  shares and the Trustees  shall  promptly
call a meeting for such purpose when requested to do so in writing by the record
holders  of  not  less  than  10%  of  the  outstanding  shares  of  the  Trust.
Shareholders   may,  under  certain   circumstances,   communicate   with  other
shareholders in connection  with  requesting a special meeting of  shareholders.
However, at any time that less than in a majority of the Trustees holding office
were elected by the  shareholders,  the Trustees will call a special  meeting of
shareholders for the purpose of electing Trustees.

                                       48

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

   
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  starter,  credit card or third party checks.  All
checks  returned by the post office as  undeliverable  will be reinvested at net
asset  value in the fund or funds from which a  redemption  was made or dividend
paid. 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. For telephone transactions, the transfer agent 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,  the transfer agent 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.
    

TAX STATUS

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

   
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.
                                       49
<PAGE>

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

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

Foreign  exchange  gains and  losses  realized  by the Fund in  connection  with
certain  transactions  involving foreign  currency-denominated  debt securities,
certain  foreign  currency   futures  and  options,   foreign  currency  forward
contracts,  foreign  currencies,  or payables or  receivables  denominated  in a
foreign  currency are subject to Section 988 of the Code, which generally causes
such gains and losses to be treated as ordinary income and losses and may affect
the amount, timing and character of distributions to shareholders.  Transactions
in foreign  currencies that are not directly related to the Fund's investment in
stock or  securities,  possibly  including  speculative  currency  positions  or
currency  derivatives not used for hedging purposes,  may increase the amount of
gain it is  deemed  to  recognize  from  the  sale  of  certain  investments  or
derivatives  held for less than three  months,  which gain is limited  under the
Code to less than 30% of gross  income for each  taxable  year,  and could under
future  Treasury  regulations  produce income not among the types of "qualifying
income"  from  which the Fund must  derive at least 90% of its gross  income for
each  taxable  year.  If the net  foreign  exchange  loss for a year  treated as
ordinary  loss under  Section 988 were to exceed the Fund's  investment  company
taxable income  computed  without regard to such loss but after  considering the
post-October  loss regulations the resulting overall ordinary loss for such year
would not be deductible by the Fund or its shareholders in future years.

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

If the Fund makes this  election,  shareholders  may then  deduct  such pro rata
portions of qualified  foreign  taxes in computing  their taxable  incomes,  or,
alternatively,   use  them  as  foreign  tax  credits,   subject  to  applicable
limitations,  against their U.S.  Federal income taxes.  Shareholders who do not
itemize deductions for Federal income tax purposes will not, however, be able to
deduct  their pro rata  portion  of  qualified  foreign  taxes paid by the Fund,
although such shareholders will be required to include their share of such taxes
in gross  income.  Shareholders  who claim a foreign tax credit for such foreign
taxes may be required to treat a portion of dividends  received from the Fund as
a separate  category of income for purposes of computing the  limitations on the
foreign tax credit. 

                                       50
<PAGE>

Tax-exempt  shareholders  will  ordinarily not benefit from this election.  Each
year (if any) that the Fund files the election described above, its shareholders
will be  notified  of the  amount of (i) each  shareholder's  pro rata  share of
qualified  foreign taxes paid by the Fund and (ii) the portion of Fund dividends
which represents  income from each foreign  country.  A Fund that cannot or does
not make this  election may deduct such taxes in  determining  the amount it has
available for distribution to shareholders,  and shareholders  will not, in this
event, include these foreign taxes in their income, nor will they be entitled to
any tax deductions or credits with respect to such taxes.

The Fund is  permitted  to acquire  stock in foreign  corporations.  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 any such election could require the Fund to recognize taxable
income or gain without the concurrent  receipt of cash. Those  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  to  minimize  its tax  liability  or  maximize  its return from these
investments.

The amount of the Fund's net realized  capital gains,  if any, in any given year
will vary depending upon the 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  or enter into options or futures  transactions  that will
generate capital gains. At the time of an investor's  purchase of Fund shares, a
portion of the purchase  price is often  attributable  to realized or unrealized
appreciation in the Fund's  portfolio.  Consequently,  subsequent  distributions
from such  appreciation  may be taxable to such  investor  even if the net asset
value of the  investor's  shares is, as a result of the  distributions,  reduced
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. Any 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 same Fund within a period of
61 days  beginning  30 days  before  and  ending 30 days  after the  shares  are
disposed of, such as pursuant to  automatic  dividend  reinvestments.  In such a
case,  the  basis  of the  shares  acquired  will be  adjusted  to  reflect  the
disallowed  loss.  Any loss  realized  upon the  redemption of shares with a tax
holding period of six months or less will be treated as a long-term capital loss
to the extent of any amounts treated as distributions of long-term  capital gain
with respect to such shares.  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.
                                          
                                       51

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 by the Fund, each
shareholder  would be treated for Federal income tax purposes as if the Fund had
distributed  to him on the last day of its  taxable  year his pro rata  share of
such  excess,  and he had paid his pro rata  share of the taxes paid by the Fund
and reinvested the remainder in the Fund.  Accordingly,  each shareholder  would
(a) include his pro rata share of such excess as  long-term  capital gain income
in his return for his taxable year in which the last day of such Fund's  taxable
year falls,  (b) be  entitled  either to a tax credit on his return for, or to a
refund  of,  his pro  rata  share of the  taxes  paid by such  Fund,  and (c) be
entitled to increase  the  adjusted tax basis for his shares in such Fund by the
difference  between  his pro rata share of such excess and his pro rata share of
such taxes.

For  Federal  income tax  purposes,  the Fund is  generally  permitted  to carry
forward a net capital loss in any year to offset its own net capital  gains,  if
any,  during  the eight  years  following  the year of the loss.  To the  extent
subsequent net capital gains are offset by such losses, they would not result in
Federal  income tax  liability  to the Fund and,  as noted  above,  would not be
distributed as such to shareholders. As of May 31, 1998, the Fund has no capital
loss carryforwards.
    

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

                                       52
<PAGE>

regulations,  all such reportable  distributions  and proceeds may be subject to
backup  withholding  of  federal  income  tax at the  rate of 31% in the case of
non-exempt shareholders who fail to furnish the Fund with their correct taxpayer
identification number and certain  certifications  required by the IRS or if the
IRS or a broker  notifies the Fund that the number  furnished by the shareholder
is  incorrect  or that the  shareholder  is subject to backup  withholding  as a
result of failure to report interest or dividend income.  The Fund may refuse to
accept an application that does not contain any required taxpayer identification
number or  certification  that the number  provided  is  correct.  If the backup
withholding  provisions are  applicable,  any such  distributions  and proceeds,
whether taken in cash or  reinvested  in shares,  will be reduced by the amounts
required  to be  withheld.  Any  amounts  withheld  may be  credited  against  a
shareholder's U.S. federal income tax liability.  Investors should consult their
tax advisers about the applicability of the backup withholding provisions.

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

Investments in debt  obligations  that are at risk of or are in default  present
special tax issues for the Fund.  Tax rules are not entirely  clear about issues
such as when the Fund may cease to accrue interest,  original issue discount, or
market discount,  when and to what extent  deductions may be taken for bad debts
or worthless securities,  how payments received on obligations in default should
be  allocated  between  principal  and  income,  and whether  exchanges  of debt
obligations  in a workout  context are  taxable.  These and other issues will be
addressed by the Fund that holds such obligations in order to reduce the risk of
distributing   insufficient  income  to  preserve  its  status  as  a  regulated
investment  company  and seek to avoid  becoming  subject to  Federal  income or
excise tax.

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

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

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.
                                       53
<PAGE>

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.

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

CALCULATION OF PERFORMANCE
   
The Fund may advertise yield, where appropriate. For the 30-day period ended May
31,  1998,  the  yields of the Fund's  Class A, Class B and Class C shares  were
9.23%, 8.89% and 8.89%, respectively.
    

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

                                                    6
                        Yield = 2 ( [ (a - b) + 1 ]   - 1
                                       -----
                                        cd
Where:

         a =      dividends and interest earned during the period.
         b =      net expenses accrued during the period.
         c =      the average daily number of fund shares  outstanding  during
                  the period that would be entitled to receive dividends.
         d =      the maximum  offering price per share on the last day of the 
                  period (NAV where applicable).

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

Set forth  below are tables  showing the  performance  on a total  return  basis
(i.e., with all dividends and distributions reinvested) of a hypothetical $1,000
investment in the Class A and Class B shares of the Fund.  Class C shares of the
Fund commenced operations on May 1, 1998; therefore,  there is no average annual
total return to report.

*        Commencement of operations.

Total Return.  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

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

Because  each class has its own  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 is applied at the end of the  period.  This  calculation  assumes  that all
dividends  and   distributions   are  reinvested  at  net  asset  value  on  the
reinvestment dates during the period.  The "distribution  rate" is determined by
annualizing the result of dividing the declared dividends of the Fund during the
period stated by the maximum offering price or net asset value at the end of the
period.  Excluding the Fund's sales charge from the distribution rate produces a
higher rate.

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

                                       55

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 reflects the market-related  risk of the Fund by showing how
responsive the Fund is to the market.

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

BROKERAGE ALLOCATION

Decisions  concerning  the  purchase and sale of  portfolio  securities  and the
allocation  of  brokerage  commissions  are  made  by the  Adviser  pursuant  to
recommendations made by an investment  committee of the Adviser,  which consists
of officers  and  directors of the Adviser and  affiliates  and Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner  which,  in the opinion of the  Adviser,  will offer the best
price and market for the  execution  of each such  transaction.  Purchases  from
underwriters  of portfolio  securities  may include a commission or  commissions
paid by the issuer  and  transactions  with  dealers  serving  as market  makers
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 NASD 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,
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

                                       56
<PAGE>

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,  the policies and practices of
the Adviser in this  regard must be  consistent  with the  foregoing  and at all
times be subject to review by the Trustees.

The negotiated brokerage commissions of the Fund are as follows:

   
(a) $356,682 for the fiscal year ended May 31, 1998,  (b) $67,481 for the period
from  November  1, 1996 to May 31,  1997 (c)  $39,163  for the fiscal year ended
October 31, 1996; and (d) $40,228 for the fiscal year ended October 31, 1995.
    

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.  For the fiscal year ended May 31,  1998,  the Fund
paid $12,630 in commissions to compensate  brokers for research services such as
industry, economic and company reviews and evaluations of securities.

The Adviser's indirect parent, the Life Company is the indirect sole shareholder
of  John  Hancock  Distributors,   Inc.,  a  broker-dealer   ("Distributors"  or
"Affiliated  Broker").  Pursuant to  procedures  determined  by the Trustees and
consistent  with the above  policy of obtaining  best net results,  the Fund may
execute  portfolio  transactions  with or through  Affiliated  Brokers.  For the
fiscal  years  ended  October  31,  1995 and 1996,  the Fund  paid no  brokerage
commission to any Affiliated Broker. For the period from November 1, 1996 to May
31, 1997, the Fund paid no brokerage  commissions to any Affiliated  Broker. For
the fiscal year ended May 31, 1998,  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  Investment  Company
Act) of the Fund,  the Adviser or the  Affiliated  Broker.  Because the Adviser,
which is affiliated with the Affiliated Broker, has, as an investment adviser to
the Fund,  the  obligation  to provide  investment  management  services,  which
includes elements of research and related investment  skills,  such research and
related  skills  will  not be  used by the  Affiliated  Brokers  as a basis  for
negotiating commissions at a rate higher than that determined in accordance with
the above criteria.
                                       57
<PAGE>

Other investment  advisory clients advised by the Adviser may also invest in the
same  securities as the Fund. When these clients buy or sell the same securities
at  substantially  the same time, the Adviser may average the transactions as to
price and  allocate the amount of  available  investments  in a manner which the
Adviser  believes to be equitable to each client,  including  the Fund.  In some
instances,  this  investment  procedure may  adversely  affect the price paid or
received by the Fund or the size of the position obtainable for it. On the other
hand, to the extent  permitted by law, the Advisers may aggregate  securities to
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 Hancock Way, Suite 1000,  Boston,  MA
02217-1000,  a  wholly-owned  indirect  subsidiary of the Life  Company,  is the

Services an annual fee of $20.00 for each Class A  shareholder  account,  $22.50
for each Class B  shareholder  account  and $21.50 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.

APPENDIX-A

MORE ABOUT RISK

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

A fund is 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 the fund utilizes these
securities  or  practices,  its  overall  performance  may be  affected,  either
positively  or  negatively.  On the  following  pages are brief  definitions  of
certain  associated  risks with them,  with examples of related  securities  and
investment  practices included in brackets.  See the "Investment  Objectives and
Policies" and "Investment Restrictions" sections of this Statement of Additional
Information  for a  description  of this Fund's  investment  policies.  The fund
follows certain policies that may reduce these risks.

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

TYPES OF INVESTMENT RISK

Correlation risk The risk that changes in the value of a hedging instrument will
not match those of the asset being hedged  (hedging is the use of one investment
to offset the effects of another investment).  Incomplete correlation can result
in unanticipated risks. (e.g., currency contracts,  futures and related options,
options on securities and indices, swaps, caps, floors and collars).

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.  (e.g., non-  investment-grade debt securities,  borrowing;  reverse
repurchase  agreements,  covered mortgage dollar roll  transactions,  repurchase
agreements,  securities lending, brady bonds, foreign debt securities,  in-kind,
delayed   and   zero   coupon   debt   securities,    asset-backed   securities,
mortgage-backed  securities,  participation  interest,  options  on  securities,
structured securities and swaps, caps floors and collars).

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.(e.g.,  foreign debt
securities, currency contracts, swaps, caps, floors and collars).

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

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.  (e.g.,
non-investment-grade debt securities, covered mortgage dollar roll transactions,
brady bonds,  foreign  debt  securities,  in-kind,  delayed and zero coupon debt
securities, asset-backed securities,  mortgage-backed securities,  participation
interest, swaps, caps, floors and collars).

                                      A-1
<PAGE>

Leverage risk  Associated  with securities or practices (such as borrowing) that
multiply  small index or market  movements  into large  changes in value.  (e.g.
borrowing;   reverse  repurchase   agreements,   covered  mortgage  dollar  roll
transactions,   when-issued   securities  and  forward   commitments,   currency
contracts,   financial  futures  and  options;  securities  and  index  options,
structured securities, swaps, caps, floors and collars).

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. (e.g. non-investment-grade debt securities, restricted and illiquid
securities,   mortgage-backed   securities,   participation  interest,  currency
contracts, futures and related options; securities and index options, structured
securities, swaps, caps, floors and collars).

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

Market risk The risk that the market  value of a security  may move up and down,
sometimes rapidly and unpredictably.  Market risk may affect a single issuer, an
industry,  a sector of the bond  market or the market as a whole.  Common to all
stocks  and bonds and the  mutual  funds  that  invest  in them.  (e.g.  covered
mortgage dollar roll transactions,  short-term trading,  when-issued  securities
and forward commitments, brady bonds, foreign debt securities,  in-kind, delayed
and zero coupon debt securities,  restricted and illiquid securities, rights and
warrants,  financial  futures and options;  and  securities  and index  options,
structured securities).

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.(e.g.   covered  mortgage  dollar  roll  transactions,   when-issued
securities and forward  commitments,  currency contracts,  financial futures and
options; securities and securities and index options).

Political  risk The risk of  losses  attributable  to  government  or  political
actions, from changes in tax or trade statutes to governmental collapse and war.
(e.g., brady bonds and foreign debt securities).

                                      A-2
<PAGE>

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

Valuation  risk The risk that a fund has valued  certain of its  securities at a
higher  price  than it can  sell  them  for.  (e.g.,  non-investment-grade  debt
securities,  participation interest,  structured securities, swaps, caps, floors
and collars).

APPENDIX B

   
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.

Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

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

                                      B-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.

CCC: Debt rated 'CCC' has a currently identifiable vulnerability to default, and
is dependent upon favorable business, financial, and economic conditions to meet
timely  payment of interest and repayment of principal.  In the event of adverse
business,  financial  or  economic  conditions,  it is not  likely  to have  the
capacity to pay interest and repay principal.  The 'CCC' rating category is also
used for debt  subordinated to senior debt that is assigned an actual or implied
'B' or 'B-' rating.

CC: The rating 'CC' is typically applied to debt subordinated to senior debt
that is assigned an actual or implied 'CCC' rating.

FITCH INVESTORS SERVICE ("Fitch")

AAA, AA, A, BBB - Bonds rated AAA are  considered to be investment  grade and of
the highest quality.  The obligor has an  extraordinary  ability to pay interest
and repay principal,  which is unlikely to be affected by reasonably foreseeable
events.  Bonds  rated  AA are  considered  to be  investment  grade  and of high
quality.  The obligor's ability to pay interest and repay principal,  while very
strong,  is  somewhat  less than for AAA rated  securities  or more  subject  to
possible  change over the term of the issue.  Bonds rated A are considered to be
investment grade and of good quality.  The obligor's ability to pay interest and
repay  principal  is  considered  to be strong,  but may be more  vulnerable  to
adverse changes in economic  conditions and circumstances than bonds with higher
ratings.  Bonds  rated  BBB  are  considered  to  be  investment  grade  and  of
satisfactory  quality. The obligor's ability to pay interest and repay principal
is  considered  to be  adequate.  Adverse  changes in  economic  conditions  and
circumstances,  however,  are more likely to weaken this ability than bonds with
higher ratings.
                                      B-2

<PAGE>


TAX-EXEMPT NOTE RATINGS

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

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

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

CORPORATE AND TAX-EXEMPT COMMERCIAL PAPER RATINGS

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

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

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

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

ORGANIZATION OF THE FUND

The Fund is a series of the Trust,  an open-end  investment  management  company
organized as a Massachusetts  business trust under the laws of The  Commonwealth
of Massachusetts.  Prior to December 22, 1994, the Fund was called  Transamerica
Government  Income Fund. Prior to August 30, 1996, the Fund was a series of John
Hancock Series, Inc., a Maryland corporation.

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

INVESTMENT OBJECTIVE AND POLICIES

The following  information  supplements the discussion of the Fund's  investment
objectives and policies discussed in the Prospectus. Appendix A contains further
information describing investment risks. The investment objective of the Fund is
non-fundamental. There is no assurance that the Fund will achieve its investment
objective.

The  Fund's  investment  objective  is to earn a high  level of  current  income
consistent  with  preservation  of capital by investing  primarily in securities
that  are  issued  or  guaranteed  as to  principal  and  interest  by the  U.S.
Government, its agencies or instrumentalities.  The Fund may seek to enhance its
current  return  and may seek to hedge  against  changes  in  interest  rates by
engaging in transactions involving options (subject to certain limits),  futures
and options on futures.

The Fund expects that under normal market conditions, it will invest a least 80%
of its total  assets  in U.S.  Government  securities  (and  related  repurchase
agreements and forward commitments) which include:

         1.  Obligations  issued by the U.S.  Treasury  differing  only in their
interest rates, maturities and times of issuance:

         (a)  U.S. Treasury bills with a maturity of one year or less;

         (b) U.S. Treasury notes with maturities of one to ten years; or

         (c) U.S. Treasury bonds generally with maturities greater than ten
             years; and

         2.  Obligations  issued  or  guaranteed  by the  U.S.  Government,  its
agencies or instrumentalities which may be supported by:

         (a) the full faith and credit of the U.S. Government (e.g., direct
             pass-through certificates of the Government National Mortgage
             Association ("Ginnie Mae"));

         (b) the right of the issuer to borrow from the U.S.  Government  (e.g.,
             securities of the Federal Home Loan banks); or

         (c) the credit of the  instrumentality  (e.g.,  bonds issued by Federal
             National Mortgage Association.)

                                       2
<PAGE>

The Adviser will attempt to minimize  excessive  fluctuations in net asset value
per share, so at times the highest yielding government securities then available
may not be  selected  for  investment  if,  in the view of the  Adviser,  future
interest  rate  movements   could  result  in  depreciation  of  value  of  such
securities.  The Fund may take full  advantage of the entire range of maturities
of  U.S.  Government  securities  and may  adjust  the  dollar-weighted  average
maturity of its portfolio from time to time based in large part on the Adviser's
expectation as to future changes in interest rates.

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

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

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

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

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

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

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

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

                                       3

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

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

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

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

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

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

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

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

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

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

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

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

                                       5
<PAGE>

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

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

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

Planned  amortization  class ("PAC") and target  amortization  class ("TAC") CMO
bonds involve less exposure to prepayment, extension and interest rate risk than
other Mortgage-Backed  Securities,  provided that prepayment rates remain within
expected  prepayment  ranges or "collars." To the extent that  prepayment  rates
remain within these prepayment  ranges,  the residual or support tranches of PAC
and TAC CMOs  assume the extra  prepayment,  extension  and  interest  rate risk
associated with the underlying mortgage assets.

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

Inverse Floating Rate  Securities.  The Fund may invest in inverse floating rate
securities. The interest rate on an inverse floating rate security resets in the
opposite  direction  from the  market  rate of  interest  to which  the  inverse
floating  rate  security is indexed.  An inverse  floating  rate security may be
considered  to be  leveraged  to the extent that its  interest  rate varies by a
multiple  of the index rate of  interest.  A higher  degree of  leverage  in the
inverse  floating  rate security is  associated  with greater  volatility in the
market value of such security.
                                       6
<PAGE>

The inverse floating rate securities that the Fund may invest in include but are
not limited to, an inverse floating rate class of a government agency issued CMO
and a government agency issued yield curve note. Typically,  an inverse floating
rate class of a CMO is one of two components  created from the cash flows from a
pool of fixed rate mortgages. The other component is a floating rate security in
which the amount of interest payable varies directly with a market interest rate
index.  A yield curve note is a fixed income  security that bears  interest at a
floating rate that is reset  periodically  based on an interest rate  benchmark.
The interest  rate resets on a yield curve note in the opposite  direction  from
the interest rate benchmark.

Mortgage  "Dollar Roll"  Transactions.  The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers  pursuant to which the
Fund sells Mortgage-Backed Securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date.  The Fund will only enter into covered rolls. A "covered roll" is a
specific type of dollar roll for which there is an offsetting cash position or a
cash  equivalent  security  position  which  matures  on or before  the  forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior  security and will be excluded from the  calculation
of the Fund's borrowing and other senior securities. For financial reporting and
tax  purposes,   the  Fund  treats   mortgage   dollar  rolls  as  two  separate
transactions;   one  involving  the  purchase  of  a  security  and  a  separate
transaction  involving a sale.  The Fund currently does not intend to enter into
mortgage rolls that are accounted for as financing.

Pay-In-Kind,  Delayed and Zero Coupon Bonds. The Fund may invest in pay-in-kind,
delayed and zero coupon bonds.  These are  securities  issued at a discount from
their face  value  because  interest  payments  are  typically  postponed  until
maturity.  The amount of the discount rate varies depending on factors including
the time remaining until  maturity,  prevailing  interest rates,  the security's
liquidity and the issuer's  credit quality.  These  securities also may take the
form of debt  securities that have been stripped of their interest  payments.  A
portion of the discount with respect to stripped tax-exempt  securities or their
coupons  may be  taxable.  The market  prices of  pay-in-kind,  delayed and zero
coupon  bonds   generally   are  more   volatile   than  the  market  prices  of
interest-bearing  securities  and are likely to  respond to a greater  degree to
changes  in  interest  rates than  interest-bearing  securities  having  similar
maturities and credit quality.  The Fund's  investments in pay-in-kind,  delayed
and zero  coupon  bonds may require  the Fund to sell  certain of its  portfolio
securities to generate  sufficient cash to satisfy  certain income  distribution
requirements.  See "Tax Status." At times when the Fund invests in  pay-in-kind,
delayed and zero coupon bonds, it will not be pursuing its primary  objective of
maximizing current income.

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

Swaps,  Caps,  Floors  and  Collars.  As one way of  managing  its  exposure  to
different types of investments,  the Fund may enter into interest rate swaps and
other types of swap  agreements such as caps,  collars and floors.  In a typical
interest  rate  swap,  one party  agrees  to make  regular  payments  equal to a
floating  interest  rate  times a  "notional  principal  amount,"  in return for
payments equal to a fixed rate times the same amount,  for a specified period of
time.  Swaps may also depend on other  prices or rates,  such as the value of an
index or mortgage prepayment rates.
                                       7
<PAGE>

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

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

Swap agreements are sophisticated  hedging  instruments that typically involve a
small  investment  of cash  relative to the  magnitude  of risks  assumed.  As a
result,  swaps can be highly volatile and may have a considerable  impact on the
Fund's  performance.  Swap  agreements  are  subject  to  risks  related  to the
counterparty's   ability  to   perform,   and  may   decline  in  value  if  the
counterparty's creditworthiness deteriorates. The Fund may also suffer losses if
it is unable to terminate  outstanding  swap  agreements  or reduce its exposure
through offsetting transactions.  The Fund will maintain in a segregated account
with its custodian,  cash or liquid  securities equal to the net amount, if any,
of the excess of the Fund's  obligations over its  entitlements  with respect to
swap, cap, collar or floor transactions.

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

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

Credit  card  receivables  are  generally  unsecured  and  the  debtors  on such
receivables  are  entitled  to the  protection  of a number of state and federal
consumer  credit  laws,  many of which  give such  debtors  the right to set-off
certain  amounts  owed on the credit  cards,  thereby  reducing the balance due.
Automobile  receivables  generally are secured,  but by automobiles  rather than
residential  real property.  Most issuers of automobile  receivables  permit the
loan  servicers  to retain  possession  of the  underlying  obligations.  If the
servicer were to sell these  obligations to another party,  there is a risk that
the purchaser  would acquire an interest  superior to that of the holders of the
asset-backed  securities.  In addition,  because of the large number of vehicles
involved in a typical issuance and technical  requirements under state laws, the
trustee  for the  holders of the  automobile  receivables  may not have a proper
security  interest  in  the  underlying  automobiles.  Therefore,  there  is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

                                       8

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

See Appendix B to this Statement of Additional  Information  which describes the
characteristics of corporate bonds in the various rating categories.

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

The market price and liquidity of lower rated fixed income securities  generally
respond to short term corporate and market developments to a greater extent than
do the price and liquidity of higher rated securities  because such developments
are perceived to have a more direct  relationship to the ability of an issuer of
such lower rated securities to meet its ongoing debt obligations.

Reduced  volume  and  liquidity  in the high yield  bond  market or the  reduced
availability of market  quotations will make it more difficult to dispose of the
bonds and to value  accurately the Fund's assets.  The reduced  availability  of
reliable,  objective  data may  increase  the Fund's  reliance  on  management's
judgment in valuing high yield bonds.  In addition,  the Fund's  investments  in
high yield  securities  may be  susceptible  to adverse  publicity  and investor
perceptions,  whether  or not  justified  by  fundamental  factors.  The  Fund's
investments, and consequently its net asset value, will be subject to the market
fluctuations and risks inherent in all securities.

Brady  Bonds.  The Fund may invest up to 10% of total  assets in Brady Bonds and
other  sovereign debt  securities of countries that have  restructured or are in
the process of  restructuring  sovereign debt pursuant to the Brady Plan.  Brady
Bonds are debt securities  described as part of a restructuring  plan created by
U.S.  Treasury  Secretary  Nicholas F. Brady in 1989 as a  mechanism  for debtor
nations to  restructure  their  outstanding  external  indebtedness  (generally,
commercial bank debt). In  restructuring  its external debt under the Brady Plan
framework,  a debtor nation negotiates with its existing bank lenders as well as
multilateral  institutions such as the World Bank and the International Monetary
Fund (the "IMF"). The Brady Plan facilitate the exchange of commercial bank debt
for newly issued debt (known as Brady Bonds). The World Bank and the IMF provide
funds pursuant to loan agreements or other  arrangements which enable the debtor
nation to  collateralize  the new Brady Bonds or to repurchase  outstanding bank
debt at a discount.  Under these arrangements IMF debtor nations are required to
implement domestic monetary and fiscal reforms.  These reforms have included the
liberalization of trade and foreign investment, the privatization of state-owned
enterprises and the setting of targets for public spending and borrowing.

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

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

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

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

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

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

Because foreign  securities may be denominated in currencies other than the U.S.
dollar,  changes in foreign  currency  exchange rates will affect the Fund's net
asset  value,  the value of  dividends  and  interest  earned,  gains and losses
realized on the sale of securities, and any net investment income and gains that
the Fund distributes to shareholders. Securities transactions undertaken in some
foreign markets may not be settled promptly,  so that the Fund's  investments on
foreign  exchanges  may be less  liquid and  subject to the risk of  fluctuating
currency exchange rates pending settlement.

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

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

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

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

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

                                       11
<PAGE>

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.  The Fund will also continue to
be subject to the risk of a decline in the market value of the  securities  sold
under the agreements  because it will reacquire those  securities upon effecting
their repurchase.  To minimize various risks associated with reverse  repurchase
agreements,  the Fund will  establish 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 not enter into reverse repurchase agreements and
other  borrowings  exceeding  in the  aggregate  more than 33 1/3% of the market
value of its total assets.  The Fund will not make additional  investments while
borrowings (including reverse repurchase  agreements) are in excess of 5% of the
Fund's 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.

Restricted Securities.  The Fund may purchase securities that are not registered
("restricted  securities")  under  the  Securities  Act of  1933  ("1933  Act"),
including  commercial  paper  issued in reliance on section 4(2) of the 1933 Act
and securities offered and sold to "qualified  institutional  buyers" under Rule
144A  under the 1933 Act.  The Fund will not  invest  more than 10% of its total
assets in illiquid  investments,  based upon a continuing  review of the trading
markets for specific Section 4(2) paper or Rule 144A  securities,  that they are
liquid, they will not be subject to the 10% limit on illiquid  investments.  The
Trustees may adopt  guidelines and delegate to the Adviser the daily function of
determining and monitoring the liquidity of restricted securities. The Trustees,
however, will retain sufficient oversight and be ultimately  responsible for the
determinations.  The Trustees will carefully  monitor 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.  These
options  may be listed on  national  domestic  securities  exchanges  or foreign
securities  exchanges  or traded in the  over-the-counter  market.  The Fund may
write  covered put and call options and purchase put and call options to enhance
total  return,  as a  substitute  for the purchase or sale of  securities  or to
protect  against  declines  in the value of  portfolio  securities  and  against
increases in the cost of securities to be acquired.

Writing Covered Options.  A call option on securities 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.
                                       12
<PAGE>

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

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

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

                                       13
<PAGE>

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

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

Reasons for the absence of a liquid  secondary market on an exchange include the
following:  (i) there may be insufficient  trading  interest in certain options;
(ii)  restrictions  may be imposed by an  exchange  on opening  transactions  or
closing  transactions  or  both;  (iii)  trading  halts,  suspensions  or  other
restrictions  may be imposed  with  respect to  particular  classes or series of
options;   (iv)  unusual  or  unforeseen   circumstances  may  interrupt  normal
operations  on an  exchange;  (v) the  facilities  of an exchange or the Options
Clearing  Corporation may not at all times be adequate to handle current trading
volume;  or (vi) one or more  exchanges  could,  for economic or other  reasons,
decide or be compelled at some future date to discontinue the trading of options
(or a particular class or series of options). 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 and securities  prices.  The
Fund may purchase and sell various kinds of futures contracts,  and purchase and
write call and put options on these futures  contracts.  The Fund may also enter
into  closing  purchase  and  sale  transactions  with  respect  to any of these
contracts and options.  The futures contracts may be based on various securities
(such  as  U.S.  Government  securities),  securities  indices,  and  any  other
financial  instruments and indices.  All futures  contracts  entered into by the
Fund are  traded on U.S.  or  foreign  exchanges  or  boards  of trade  that are
licensed,  regulated or approved by the  Commodity  Futures  Trading  Commission
("CFTC").
                                       14
<PAGE>

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.  When
interest rates are rising or securities prices are falling, the Fund can seek to
offset a decline in the value of its current  portfolio  securities  through the
sale of futures contracts.  When interest rates are falling or securities prices
are rising, the Fund, through the purchase of futures contracts,  can attempt to
secure  better  rates or prices than might later be available in the market when
it effects anticipated purchases.

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

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

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

On other  occasions,  the Fund may take a "long" position by purchasing  futures
contracts.  This  would be done,  for  example,  when the Fund  anticipates  the
subsequent purchase of particular securities when it has the necessary cash, but
expects the prices 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  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

                                       15
<PAGE>

underlying  futures  contract  at any time  during  the  option  period.  As the
purchaser  of an option on a futures  contract,  the Fund obtains the benefit of
the futures position if prices move in a favorable direction but limits its risk
of loss in the event of an unfavorable price movement to the loss of the premium
and transaction costs.

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

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

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

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

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

While  transactions  in futures  contracts  and  options  on futures  may reduce
certain risks,  these  transactions  themselves  entail certain other risks. For
example,  unanticipated  changes  in  interest  rates or  securities  prices  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.

                                       16
<PAGE>

Perfect correlation between the Fund's futures positions and portfolio positions
will be impossible to achieve. 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 markets
funds.  When the  Fund  lends  portfolio  securities,  there is a risk  that the
borrower may fail to return the  securities  involved in the  transaction.  As a
result, the Fund may incur a loss or, in the event of the borrower's bankruptcy,
the Fund may be delayed in or prevented from liquidating the collateral. It is a
fundamental  policy of the Fund not to lend portfolio  securities having a total
value exceeding 30% of its total assets.

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

Forward Commitment and When-Issued Securities.  The Fund may purchase securities
on a when-issued or forward commitment basis. "When-issued" refers to securities
whose terms are available and for which a market exists, but which have not been
issued.  The Fund will  engage  in  when-issued  transactions  with  respect  to
securities  purchased for its portfolio in order to obtain what is considered to
be an  advantageous  price  and  yield  at  the  time  of the  transaction.  For
when-issued  transactions,  no payment is made until  delivery  is due,  often a
month or more after the purchase. In a forward commitment transaction,  the Fund
contracts  to  purchase  securities  for a fixed  price at a future  date beyond
customary settlement time.
                                       17
<PAGE>

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

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

Short-Term Trading and Portfolio Turnover. Short-term trading means the purchase
and subsequent sale of a security after it has been held for a relatively  brief
period of time.  The Fund may engage in short-term  trading in response to stock
market  conditions,  changes  in  interest  rates or other  economic  trends and
developments,  or to take advantage of yield  disparities  between various fixed
income  securities  in  order  to  realize  capital  gains  or  improve  income.
Short-term trading may have the effect of increasing  portfolio turnover rate. A
high rate of  portfolio  turnover  (100% or  greater)  involves  correspondingly
greater  brokerage  transaction  expenses and may make it more difficult for the
Fund to  qualify  as a  regulated  investment  company  for  federal  income tax
purposes. The Fund's portfolio 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  Statement of Additional  Information),  or
pledge,  mortgage or hypothecate an amount of its assets (taken at market value)
in excess of 15% of its total assets, in each case taken at the lower of cost or
market value. For the purpose of this restriction,  collateral arrangements with
respect  to  options,  futures  contracts,  options  on  futures  contracts  and
collateral  arrangements  with respect to initial and variation  margins are not
considered a pledge of assets.

(2)      Underwrite  securities  issued by other persons  except  insofar as the
Fund may  technically be deemed an underwriter  under the Securities Act of 1933
in selling a portfolio security.
                                       18

<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 (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.

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

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

(8)      Purchase or retain in its portfolio any securities  issued by an issuer
any of whose officers,  directors, trustees or security holders is an officer or
Trustee of such  Fund,  or is a member,  partner,  officer  or  Director  of the
Adviser,  if after the purchase of the securities of such issuer by 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. 

                                       19

<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  (the  "Investment  Company  Act")  if  such  issuance  is
specifically  prohibited  by  the  Investment  Company  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)     The Fund may not  invest  more than 25% of its total  assets  (taken at
market  value)  in the  securities  of  issuers  engaged  in any  one  industry.
Obligations  issued or  guaranteed  by the U.S.  Government  or its agencies and
instrumentalities are not subject to the foregoing 25% limitation.  In addition,
for purposes of this limitation,  determinations of what constitutes an industry
are made in accordance  with specific  industry  codes set forth in the Standard
Industrial  Classification  Manual and without  considering groups of industries
(e.g., all utilities, to be an industry).

(14)     Purchase  securities  of any issuer  (other than  securities  issued or
guaranteed by the U.S. Government or its agencies or  instrumentalities) if such
purchase, at the time thereof, would cause the Fund to hold more than 10% of any
class of securities of such issuer.  For this purpose,  all  indebtedness  of an
issuer shall be deemed a single class and all preferred stock of an issuer shall
be deemed a single class.

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

(1)      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  of the  Fund's
portfolio securities,  in the securities of open-end investment companies or (b)
the purchase of shares of any  investment  company in connection  with a merger,
consolidation,  reorganization or purchase of substantially all of the assets of
another investment  company.  Subject to the above percentage  limitations,  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 or rating  restriction on investment or utilization
of assets  is  adhered  to at the time an  investment  is made or assets  are so
utilized,  a later change in percentage  resulting  from changes in the value of
the Fund's  portfolio  securities or a later change in the rating of a portfolio
security will not be considered a violation of policy.

                                       20

INVESTMENT ADVISORY AND OTHER SERVICES

The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts 02199-7603,
was  organized in 1968 and has more than $30 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 a high  rating from  Standard & Poor's and A.M.
Best.  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 Agreements,  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 cost of its  organization  and  operation,  including but not
limited to  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 custodian  including  those for keeping books and accounts,
maintaining a committed line of credit,  and  calculating the net asset value of
shares;  fees and expenses of transfer  agents and dividend  disbursing  agents;
legal, accounting,  financial, management, tax and auditing fees and expenses of
the Fund (including and allocable portion of the cost of the Adviser's employees
rendering such services to the Fund);  the compensation and expenses of Trustees
who are not other wise  affiliated  with the Trust,  the Adviser or any of their
affiliates;  expenses of Trustees' and shareholders'  meeting; trade association
memberships; insurance premiums; and any extraordinary expenses.
    

As compensation  for its services under the Advisory  Agreements,  the Fund pays
the  Adviser  monthly a fee based on a stated  percentage  of the average of the
daily net assets of the Fund as follows:
                                                                      Fee
Average Daily Net Assets                                           (Annual Rate)
- ------------------------                                           -------------

First $200 million                                                 0.650%
Next $300 million                                                  0.625%
Over $500 million                                                  0.600%

                                       30
<PAGE>

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

Pursuant to the Advisory  Agreement,  the Adviser is not liable for any error of
judgment or mistake of law or for any loss  suffered  by the Fund in  connection
with the  matters to which  their  respective  contracts  relate,  except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
the Adviser in the  performance of its duties or from its reckless  disregard of
the obligations and duties under the 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 as 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  was
approved by all of the Trustees.  The Advisory  Agreement  and the  Distribution
Agreement  discussed  below will continue in effect from year to year,  provided
that its continuance is approved  annually both (i) by the holders of a majority
of the outstanding  voting securities of the Trust or by the Trustees,  and (ii)
by a  majority  of the  Trustees  who  are  not  parties  to the  Agreement,  or
"interested  persons" of any such parties.  Both Agreements may be terminated on
60  days  written  notice  by  any  party  or by a  vote  of a  majority  of the
outstanding  voting  securities of the Fund and will terminate  automatically if
assigned.

The Advisory fees payable by the Fund to the Adviser, were as follows:

11/1/96-5/31/97                                               $1,999,643
6/1/97-5/31/98                                                $3,155,183
    

Administrative  Services  Agreement.  The  Fund  previously  was a  party  to an
administrative  services agreement (the "Services  Agreement") with Transamerica
Fund Management Company ("TFMC"),
 
                                       31
<PAGE>

pursuant to which TFMC performed bookkeeping and accounting services and
functions, including preparing and maintaining various accounting books, records
and other documents and keeping such general ledgers and portfolio accounts as
are reasonably necessary for the operation of the Fund. Other administrative
services included communications in response to shareholder inquiries and
certain printing expenses of various financial reports. In addition, such staff
and office space, facilities and equipment was provided as necessary to provide
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 1995 fiscal year.

The amount of $16,694 for the Fund reflects the total of administrative services
fees paid to the Adviser for the fiscal year ended October 31, 1995:

   
Accounting and Legal  Services  Agreement.  The Trust,  on behalf the Fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this agreement,  the Adviser  provides the Fund with certain tax,  accounting
and legal  services.  For the fiscal year ended October 31, 1996,  the Fund paid
the  Adviser  $96,304 for  services  under this  agreement.  For the period from
November 1, 1996 to May 31, 1997, the Fund paid the Adviser $59,313 for services
under this agreement.  For the fiscal year ended May 31, 1998, the Fund paid the
Adviser $88,284 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 that are  continually  offered at net asset
value next determined,  plus any 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 shares,  the broker  receives  compensation
immediately but John Hancock Funds is compensated on a deferred basis.
    

For the fiscal years ended October 31, 1995,  1996, for the period from November
1,  1996 to May 31,  1997  and for the  fiscal  year  ended  May 31,  1998,  the
following  amounts reflect (a) the total  underwriting  commissions for sales of
the Fund's  Class A shares and (b) the portion of such  amount  retained by John
Hancock Funds. The remainder of the  underwriting  commissions were reallowed to
Selling Brokers.

   
10/31/1995                                    (a) $35,314  and (b) $6,442
10/31/1996                                    (a) $515,753 and (b) $65,449
11/1/96-5/31/97                               (a) $105,964 and (b) $115,430
6/1/97-5/31/98                                (a) $176,340 and (b) $20,547

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
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  average
daily net assets  attributable to each class of shares.  The  distribution  fees
will be used to reimburse  John  Hancock  Funds for its  distribution  expenses,
including  but not limited to: (i) initial  and ongoing  sales  compensation  to
Selling Brokers and others (including  affiliates of John Hancock Funds) engaged
in the sale of Fund shares;  (ii) marketing,  promotional and overhead  expenses
incurred in  connection  with the  distribution  of Fund shares;  and (iii) with
respect to Class B shares only,  interest expenses on unreimbursed  distribution
expenses. The service fees will by used to compensate Selling Brokers and others
for providing personal and account maintenance services to shareholders.  In the
event that John Hancock Funds is not fully  reimbursed  for payments or expenses
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 Plans
will  be  carried  forward  together  with  interest  on the  balance  of  these
unreimbursed expenses. The Fund does not treat unreimbursed expenses under Class
B Plans as a liability of the Fund, because the Trustees may terminate the Class
B Plans at any time.  For the fiscal  year ended May 31,  1998 an  aggregate  of
$12,062,593 of  distribution  expenses or 8.40% of the average net assets of the
Fund's Class B shares was not  reimbursed  or  recovered  by John Hancock  Funds
through  the  receipt of  deferred  sales  charges or Rules  12b-1 fees in prior
periods.
    

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.  Each of the Plans further provides that it 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
applicable  Fund which has voting rights to that Plan. Each of the Plans provide
that no material  amendment to the Plan will be effective  unless it is approved
by a vote of a majority  of the  Trustees  and the  Independent  Trustees of the
Fund.  The holders of Class A and Class B shares have  exclusive  voting  rights
with respect to the Plan  applicable  to their  respective  class of shares.  In
adopting the Plans, the Trustees  concluded that, in their judgment,  these is a
reasonable  likelihood that the Plans will benefit the holders of the applicable
class of shares of 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,

                                       33
<PAGE>

according to a formula based upon gross sales dollars and/or average daily net
assets of each such class, as may be approved from time to time by vote of a
majority of Trustees. From time to time, the Fund may participate in joint
distribution activities with other Funds and the costs of those activities will
be borne by the Fund in proportion to the relative net asset value of the
participating Funds.

During the fiscal year ended May 31, 1998,  the Fund paid John Hancock Funds the
following amounts of expenses in connection with their services.

SALES COMPENSATION

As part of their business strategies, each of the John Hancock 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.  The sales charges and 12b-1
fees paid by investors are detailed in the  prospectus  and under  "Distribution
Contracts" in this  Statement of Additional  Information.  The portions of these
expenses  that are reallowed to financial  services  firms are shown on the next
page.
    

Whenever  you make an  investment  in the  Fund,  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.  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.

CDSC  revenues  collected by John Hancock  Funds may be used to pay  commissions
when there is no initial sales charge.

NET ASSET VALUE

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

                                       35
<PAGE>

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

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

The NAV for each class of the Fund is determined  each business day at the close
of regular trading on the New York Stock Exchange  (typically 4:00 p.m.  Eastern
Time) by dividing a class net assets by the number of its shares outstanding. On
any day an  international  market is closed and the New York Stock  Exchange  is
open,  any foreign  securities  will be valued at the prior day's close with the
current day's  exchange  rate.  Trading of foreign  securities may take place on
Saturdays and U.S.  business holidays on which 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 only
will be issued for full  shares.  The  Trustees of the Fund reserve the right to
change or waive the Fund's  minimum  investment  requirements  and to reject any
order to purchase shares  (including  purchase by exchange) when in the judgment
of the Adviser such rejection is in the Fund's best interest.

The sales  charges  applicable  to  purchases  of 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,  the investor is
entitled to accumulate  current  purchases with the greater of the current value
(at offering price) of the Class A shares of the Fund, owned by the investor, or
if John Hancock Signature Services,  Inc. ("Signature  Services") is notified by
the investor's  dealer or the investor at the time of the purchase,  the cost of
the Class A shares owned.

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

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

                                       36
<PAGE>

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

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

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

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

o        Retirement plans investing through the PruArray Program sponsored by

         Prudential Securities.
   
o        Pension plans transferring  assets from a John Hancock variable annuity
         contract to the Fund pursuant to an exemptive  application  approved by
         the Securities Exchange Commission.
    

o        Existing  full  service  clients  of the Life  Company  who were  group
         annuity  contract  holders as of  September  1, 1994,  and  participant
         directed  retirement plans with at least 100 eligible  employees at the
         inception of the Fund  account.  Each of these  investors  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.

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.

                                       37
<PAGE>

Accumulation Privilege.  Investors (including investors combining purchases) who
are  already  Class A  shareholders  may also  obtain the benefit of the reduced
sales charge by taking into account not only the amount being  invested but also
the investor's 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. Retirement plan investors may include the value of Class
B shares if class B shares held are greater  than $1 million.  Retirement  plans
must notify Signature Services to utilize.

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

Letter of Intention.  Reduced sales charges are also  applicable to  investments
made  pursuant  to a Letter  of  Intention  (the  "LOI"),  which  should be read
carefully  prior to its  execution by an  investor.  The Fund offers two options
regarding  the  specified  period  for  making  investments  under the LOI.  All
investors have the option of making their investments over a specified period of
thirteen (13) months. Investors who are using the Fund as a funding medium for a
retirement plan, however,  may opt to make the necessary  investments called for
by the LOI over a forty-eight (48) month period.  These retirement plans include
Traditional,  Roth and Education IRAs, SEP, SARSEP,  401(k),  403(b)  (including
TSAs),  SIMPLE IRA, SIMPLE 401(k),  Money Purchase  Pension,  Profit Sharing and
Section 457 plans.  Non-qualified  and  qualified  retirement  plan  investments
cannot be combined to satisfy an LOI of 48 months. Such an investment (including
accumulations  and  combinations  but not including  reinvested  dividends) must
aggregate $100,000 or more invested during the specified period from the date of
the LOI or from a date  within  ninety  (90) days prior  thereto,  upon  written
request to  Signature  Services.  The sales  charge  applicable  to all  amounts
invested  under the LOI is computed as if the  aggregate  amount  intended to be
invested had been invested immediately. If such aggregate amount is not actually
invested,  the difference in the sales charge actually paid and the sales charge
payable had the LOI not been in effect is due from the  investor.  However,  for
the purchases  actually made with the specified period (either 13 or 48 months),
the sales charge  applicable  will not be higher than that which would have been
applied  (including  accumulations  and  combinations)  had the LOI been for the
amount actually invested.

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

DEFERRED SALES CHARGE ON CLASS B

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

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

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

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

 oProceeds of 50 shares redeemed at $12 per shares (50 x 12)            $600.00
 o*Minus Appreciation ($12 - $10) x 100 shares                          (200.00)

 o Minus proceeds of 10 shares not subject to CDSC
                           (dividend reinvestment)                      (120.00)
                                                                         -------
 oAmount subject to CDSC                                                $280.00

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

                                       39

Proceeds  from the CDSC are paid to John Hancock  Funds and are used in whole or
in part by John  Hancock  Funds to defray  its  expenses  related  to  providing
distribution-related  services  to the Fund in  connection  with the sale of the
Class B shares,  such as the payment of  compensation  to select Selling Brokers
for selling Class B shares. The combination of the CDSC and the distribution and
service  fees  facilitates  the  ability  of the Fund to sell the Class B shares
without a sales charge being deducted at the time of the purchase.

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

For all account types:

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

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

*        Redemptions due to death or disability. (Does not apply to Trust
         accounts unless trust is being dissolved.)

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

*        Redemptions where the proceeds are used to purchase a John Hancock
         Declaration Variable Annuity.

*        Redemptions of Class B shares made under a periodic withdrawal plan, or
         redemptions  for fees  charged by  planners or  advisors  for  advisory
         services,  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

         Lynch Recordkeeping Service Agreement. See your Merrill Lynch financial
         consultant for further information.

         Plans, 457 and 408 (SEPs and SIMPLE IRAs) of the Internal Revenue Code.
    

*        Redemptions from certain IRA and retirement plans that purchased shares

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

SPECIAL REDEMPTIONS

Although  it  would  not  normally  do so,  the  Fund  has the  right to pay the
redemption  price  of  shares  of the  Fund in  whole  or in  part in  portfolio
securities as prescribed by the Trustees.  When the shareholder  sells portfolio
securities  received in this  fashion,  the  shareholder  will incur a brokerage
charge. Any such security would be valued for the purpose of making such payment
at the same value as used in  determining  the Fund's net asset value.  The Fund
has elected to be governed by Rule 18f-1 under the Investment Company Act. Under
that rule,  the Fund must redeem  their  shares for cash except to the extent to
that the redemption  payments to any shareholder  during any 90-day period would
exceed  the  lesser of  $250,000  or 1% of the  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 the
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 from the redemption
of shares of the Fund.  Since the redemption price of the shares of the Fund may
be more or less than the shareholder's cost,  depending upon the market value of
the securities owned by the Fund at the time of redemption,  the distribution of
cash  pursuant  to this  plan  may  result  in  realization  of gain or loss for
purposes  of  Federal,  state and  local  income  taxes.  The  maintenance  of a
Systematic  Withdrawal Plan 

                                       43
<PAGE>

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

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

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

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

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

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

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

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

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

Retirement plans participating in Merrill Lynch's servicing programs:

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

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

DESCRIPTION OF THE FUND'S SHARES

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

The shares of each class of the Fund represent an equal  proportionate  interest
in the aggregate net assets  attributable to the classes 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 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 the 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.
Fund  shareholders  may  remove a Trustee  by the  affirmative  vote of at least
two-thirds of the Trust's  outstanding  shares and the Trustees  shall  promptly
call a meeting for such purpose when requested to do so in writing by the record
holders  of  not  less  than  10%  of  the  outstanding  shares  of  the  Trust.
Shareholders   may,  under  certain   circumstances,   communicate   with  other
shareholders in connection  with  requesting a special meeting of  shareholders.
However, at any time that less than in a majority of the Trustees holding office
were elected by the  shareholders,  the Trustees will call a special  meeting of
shareholders for the purpose of electing Trustees.


                                       45

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

   
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  starter,  credit card or third party checks.  All
checks  returned by the post office as  undeliverable  will be reinvested at net
asset  value in the fund or funds from which a  redemption  was made or dividend
paid. 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. For telephone transactions, the transfer agent 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,  the transfer agent 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.
    

TAX STATUS

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

   
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. 

                                       46
<PAGE>

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

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

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

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

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

                                       47
<PAGE>

   
Upon a  redemption  or other  disposition  of shares of the Fund  (including  by
exercise of the exchange  privilege) in a transaction  that is treated as a sale
for tax  purposes,  a shareholder  may realize a taxable gain or loss  depending
upon the amount of the proceeds and the investor's basis in his shares. Any 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 same Fund within a period of
61 days  beginning  30 days  before  and  ending 30 days  after the  shares  are
disposed of, such as pursuant to  automatic  dividend  reinvestments.  In such a
case,  the  basis  of the  shares  acquired  will be  adjusted  to  reflect  the
disallowed  loss.  Any loss  realized  upon the  redemption of shares with a tax
holding period of six months or less will be treated as a long-term capital loss
to the extent of any amounts treated as distributions of long-term  capital gain
with respect to such shares.  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.
    

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 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  income in his
return for his taxable  year in which the last day of such Fund's  taxable  year
falls,  (b) be entitled either to a tax credit on his return for, or to a refund
of, his pro rata share of the taxes paid by such Fund,  and (c) be  entitled  to
increase the  adjusted  tax basis for his shares in such Fund by the  difference
between his pro rata share of such excess and his pro rata share of such taxes.

   
For Federal income tax purposes, the Fund is generally permitted to carry
forward a net capital loss in any year to offset its own net capital gains, if
any, during the eight years following the year of the loss. To the extent
subsequent net capital gains are offset by such losses, they would not result in
Federal income tax liability to the Fund and, as noted above, would not be
distributed as such to shareholders. The Fund has $18,749,417 of capital loss
carryforwards, available to the extent provided by regulations, to offset future
net realized capital gains. These carryforwards expire at various amounts and
times from 2002 through 2006.
    

The Fund is required to accrue income on any debt securities that have more than
a de minimis amount of original issue discount (or debt securities acquired at a
market  discount,  if the Fund  elects  to  include  market  discount  in income
currently) prior to the receipt of the corresponding cash payments. 

                                       48
<PAGE>

The mark to market or constructive sales rules applicable to certain options,
futures and forward contracts may also require the Fund to recognize income or
gain without a concurrent receipt of cash. However, the Fund must distribute to
shareholders for each taxable year substantially all of its net income and net
capital gains, including such income or gain, to qualify as a regulated
investment company and avoid liability for any federal income or excise tax.
Therefore, the Fund may have to dispose of its portfolio securities under
disadvantageous circumstances to generate cash, or borrow cash, to satisfy these
distribution requirements.

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

The Fund will be required to report to the Internal  Revenue Service (the "IRS")
all taxable  distributions to  shareholders,  as well as gross proceeds from the
redemption  or exchange  of Fund  shares,  except in the case of certain  exempt
recipients,  i.e.,  corporations  and certain other investors  distributions  to
which are exempt from the information  reporting  provisions of the Code.  Under
the backup withholding  provisions of Code Section 3406 and applicable  Treasury
regulations,  all such reportable  distributions  and proceeds may be subject to
backup  withholding  of  federal  income  tax at the  rate of 31% in the case of
non-exempt shareholders who fail to furnish the Fund with their correct taxpayer
identification number and certain  certifications  required by the IRS or if the
IRS or a broker  notifies the Fund that the number  furnished by the shareholder
is  incorrect  or that the  shareholder  is subject to backup  withholding  as a
result of failure to report interest or dividend income.  The Fund may refuse to
accept an application that does not contain any required taxpayer identification
number or  certification  that the number  provided  is  correct.  If the backup
withholding  provisions are  applicable,  any such  distributions  and proceeds,
whether taken in cash or  reinvested  in shares,  will be reduced by the amounts
required  to be  withheld.  Any  amounts  withheld  may be  credited  against  a
shareholder's U.S. federal income tax liability.  Investors should consult their
tax advisers about the applicability of the backup withholding provisions.

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

Investments in debt  obligations  that are at risk of or are in default  present
special tax issues for the Fund.  Tax rules are not entirely  clear about issues
such as when the Fund may cease to accrue interest,  original issue discount, or
market discount,  when and to what extent  deductions may be taken for bad debts
or worthless securities,  how payments received on obligations in default should
be  allocated  between  principal  and  income,  and whether  exchanges  of debt
obligations  in a workout  context are  taxable.  These and other issues will be
addressed by the Fund that holds such obligations in order to reduce the risk of
distributing   insufficient  income  to  preserve  its  status  as  a  regulated
investment  company  and seek to avoid  becoming  subject to  Federal  income or
excise tax.

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

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

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

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

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

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

CALCULATION OF PERFORMANCE

   
The Fund may advertise yield, where appropriate. For the 30-day period ended May
31,  1998,  the yields of the Fund's  Class A and Class B shares  were 5.21% and
4.69%, respectively.
    

                                       50
<PAGE>

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

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

Where:

         a =      dividends and interest earned during the period.
         b =      net expenses accrued during the period.
         c =      the average daily number of fund shares  outstanding  during
                  the period that would be entitled to receive dividends.
         d =      the maximum offering price per share on the last day of the 
                  period (NAV where applicable).

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

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

*        Commencement of operations.
</TABLE>
    

Total Return.  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


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

Because  each class has its own  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

                                       51
<PAGE>

in the initial investment or the CDSC is applied at the end of the period.  This
calculation  assumes that all dividends and  distributions are reinvested at net
asset value on the reinvestment dates during the period. The "distribution rate"
is determined by  annualizing  the result of dividing the declared  dividends of
the Fund  during the period  stated by the maximum  offering  price or net asset
value at the end of the  period.  Excluding  the Fund's  sales  charge  from the
distribution rate produces a higher rate.

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

From time to time, in reports and promotional  literature,  the Fund's 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 reflects the market-related  risk of the Fund by showing how
responsive the Fund is to the market.

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

BROKERAGE ALLOCATION

Decisions  concerning  the  purchase and sale of  portfolio  securities  and the
allocation  of  brokerage  commissions  are  made  by the  Adviser  pursuant  to
recommendations made by an investment  committee of the Adviser,  which consists
of officers  and  directors of the Adviser and  affiliates  and Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner  which,  in the opinion of the  Adviser,  will offer the best
price and market for the  execution  of each such  transaction.  Purchases  from
underwriters  of portfolio  securities  may include a commission or  commissions
paid by the issuer  and  transactions  with  dealers  serving  as market  makers
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.

                                       52
<PAGE>

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 NASD 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 a Fund's portfolio transactions.

To the extent  consistent  with the foregoing,  the Fund will be governed in the
selection of brokers and dealers,  and the  negotiation of brokerage  commission
rates and dealer  spreads,  by the  reliability  and  quality  of the  services,
including primarily the availability and value of research  information and to a
lesser extent statistical  assistance  furnished to the Adviser of the Fund, and
their value and expected  contribution to the performance of the Fund. It is not
possible to place a dollar value on information and services to be received from
brokers and dealers,  since it is only  supplementary to the research efforts of
the  Adviser.  The receipt of  research  information  is not  expected to reduce
significantly  the  expenses  of  the  Adviser.  The  research  information  and
statistical  assistance  furnished  by brokers  and dealers may benefit the Life
Company or other  advisory  clients of the Adviser,  and  conversely,  brokerage
commissions and spreads paid by other advisory clients of the Adviser may result
in research information and statistical  assistance  beneficial to the Fund. The
Fund  will 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,  the policies and practices of
the Adviser in this  regard must be  consistent  with the  foregoing  and at all
times be subject to review by the Trustees.


The negotiated brokerage commissions of the Fund are as follows:

   
(a) $25,004 for the fiscal year ended May 31,  1998,  (b) $59,080 for the period
from  November  1, 1996 to May 31, 1997 (c)  $135,622  for the fiscal year ended
October 31, 1996; and (d) $15,814 for the fiscal year ended October 31, 1995.

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.  For the fiscal year ended May 31,  1998,  the Fund
did not pay any commissions to compensate  brokers for research services such as
industry, economic and company reviews and evaluations of securities.
    

The Adviser's indirect parent, the Life Company is the indirect sole shareholder
of  John  Hancock  Distributors,   Inc.,  a  broker-dealer   ("Distributors"  or
"Affiliated  Broker").  Pursuant to  procedures  determined  by the Trustees and
consistent  with the above  policy of obtaining  best net results,  the Fund may
execute  portfolio  transactions  with or through  Affiliated  Brokers.  For the
fiscal  years  ended  October  31,  1995 and 1996,  the Fund  paid no  brokerage
commission to any Affiliated Broker. For the period from November 1, 1996 to May
31, 1997, the Fund paid no brokerage  commissions to any Affiliated  Broker. For
the fiscal year ended May 31, 1998,  the Fund paid no brokerage  commissions  to
any Affiliated Broker.

                                       53
<PAGE>

Distributors may act as broker for the Fund on exchange  transactions,  subject,
however,  to the general  policy of the Fund set forth above and the  procedures
adopted by the Trustees pursuant to the Investment Company Act. Commissions paid
to an  Affiliated  Broker  must be at least as  favorable  as  those  which  the
Trustees believe to be contemporaneously  charged by other brokers in connection
with comparable  transactions  involving  similar  securities being purchased or
sold. A transaction  would not be placed with an  Affiliated  Broker if the Fund
would have to pay a commission rate less favorable than the Affiliated  Broker's
contemporaneous  charges for comparable transactions for its other most favored,
but unaffiliated, customers, except for accounts for which the Affiliated Broker
acts as a clearing  broker for another  brokerage firm, and any customers of the
Affiliated  Broker not comparable to the Fund as determined by a majority of the
Trustees who are not interested  persons (as defined in the  Investment  Company
Act) of the Fund,  the Adviser or the  Affiliated  Broker.  Because the Adviser,
which is affiliated with the Affiliated 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  Brokers  as a basis  for
negotiating commissions at a rate higher than that determined in accordance with
the above criteria.

Other investment  advisory clients advised by the Adviser may also invest in the
same  securities as the Fund. When these clients buy or sell the same securities
at  substantially  the same time, the Adviser may average the transactions as to
price and  allocate the amount of  available  investments  in a manner which the
Adviser  believes to be equitable to each client,  including  the Fund.  In some
instances,  this  investment  procedure may  adversely  affect the price paid or
received by the Fund or the size of the position obtainable for it. On the other
hand, to the extent  permitted by law, the Advisers may aggregate  securities to
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 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 $20.00 for each Class A  shareholder  account,  $22.50
for each Class B 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

APPENDIX-A

MORE ABOUT RISK

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

A fund is 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 the fund utilizes these
securities  or  practices,  its  overall  performance  may be  affected,  either
positively  or  negatively.  On the  following  pages are brief  definitions  of
certain  associated  risks with them,  with examples of related  securities  and
investment  practices included in brackets.  See the "Investment  Objectives and
Policies" and "Investment Restrictions" sections of this Statement of Additional
Information  for a  description  of this Fund's  investment  policies.  The fund
follows certain policies that may reduce these risks.

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

TYPES OF INVESTMENT RISK

Correlation risk The risk that changes in the value of a hedging instrument will
not match those of the asset being hedged  (hedging is the use of one investment
to offset the effects of another investment).  Incomplete correlation can result
in unanticipated risks. (e.g., currency contracts,  futures and related options,
options on securities and indices, swaps, caps, floors and collars).

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.  (e.g., non-  investment-grade debt securities,  borrowing;  reverse
repurchase  agreements,  covered mortgage dollar roll  transactions,  repurchase
agreements,  securities lending, brady bonds, foreign debt securities,  in-kind,
delayed   and   zero   coupon   debt   securities,    asset-backed   securities,
mortgage-backed  securities,  participation  interest,  options  on  securities,
structured securities and swaps, caps floors and collars).

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.(e.g.,  foreign debt
securities, currency contracts, swaps, caps, floors and collars).

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

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.  (e.g.,
non-investment-grade debt securities, covered mortgage dollar roll transactions,
brady bonds,  foreign  debt  securities,  in-kind,  delayed and zero coupon debt
securities, asset-backed securities,  mortgage-backed securities,  participation
interest, swaps, caps, floors and collars).

                                      A-1
<PAGE>

Leverage risk  Associated  with securities or practices (such as borrowing) that
multiply  small index or market  movements  into large  changes in value.  (e.g.
borrowing;   reverse  repurchase   agreements,   covered  mortgage  dollar  roll
transactions,   when-issued   securities  and  forward   commitments,   currency
contracts,   financial  futures  and  options;  securities  and  index  options,
structured securities, swaps, caps, floors and collars).

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. (e.g. non-investment-grade debt securities, restricted and illiquid
securities,   mortgage-backed   securities,   participation  interest,  currency
contracts, futures and related options; securities and index options, structured
securities, swaps, caps, floors and collars).

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

Market risk The risk that the market  value of a security  may move up and down,
sometimes rapidly and unpredictably.  Market risk may affect a single issuer, an
industry,  a sector of the bond  market or the market as a whole.  Common to all
stocks  and bonds and the  mutual  funds  that  invest  in them.  (e.g.  covered
mortgage dollar roll transactions,  short-term trading,  when-issued  securities
and forward commitments, brady bonds, foreign debt securities,  in-kind, delayed
and zero coupon debt securities,  restricted and illiquid securities, rights and
warrants,  financial  futures and options;  and  securities  and index  options,
structured securities).

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.(e.g.   covered  mortgage  dollar  roll  transactions,   when-issued
securities and forward  commitments,  currency contracts,  financial futures and
options; securities and securities and index options).

Political  risk The risk of  losses  attributable  to  government  or  political
actions, from changes in tax or trade statutes to governmental collapse and war.
(e.g., brady bonds and foreign debt securities).

                                      A-2
<PAGE>

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

Valuation  risk The risk that a fund has valued  certain of its  securities at a
higher  price  than it can  sell  them  for.  (e.g.,  non-investment-grade  debt
securities,  participation interest,  structured securities, swaps, caps, floors
and collars).

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.

Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

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

STANDARD & POOR'S RATINGS GROUP

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

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

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

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

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

CCC: Debt rated 'CCC' has a currently identifiable vulnerability to default, and
is dependent upon favorable business, financial, and economic conditions to meet
timely  payment of interest and repayment of principal.  In the event of adverse
business,  financial  or  economic  conditions,  it is not  likely  to have  the
capacity to pay interest and repay principal.  The 'CCC' rating category is also
used for debt  subordinated to senior debt that is assigned an actual or implied
'B' or 'B-' rating.

CC: The rating 'CC' is typically applied to debt subordinated to senior debt
that is assigned an actual or implied 'CCC' rating.

FITCH INVESTORS SERVICE ("Fitch")

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

<PAGE>

TAX-EXEMPT NOTE RATINGS

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

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

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

CORPORATE AND TAX-EXEMPT COMMERCIAL PAPER RATINGS

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

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

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

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

ORGANIZATION OF THE FUND

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

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

INVESTMENT OBJECTIVE AND POLICIES

The following  information  supplements the discussion of the Fund's  investment
objective and policies discussed in the Prospectus.  Appendix A contains further
information  describing  investment  risks. The Fund's  investment  objective is
non-fundamental. There is no assurance that the Fund will achieve its investment
objective.


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

Under normal conditions, at least 80% of the Fund's total assets will be in U.S.
Government securities that consist of the following:

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

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

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

                                       2
<PAGE>

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

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

Structured  Securities.  The Fund may invest in structured  securities including
notes,  bonds or  debentures,  the value of the principal of and/or  interest on
which is to be  determined  by  reference  to changes  in the value of  specific
currencies,  interest rates, commodities,  indices or other financial indicators
(the "Reference") or the relative change in two or more References. The interest
rate  or the  principal  amount  payable  upon  maturity  or  redemption  may be
increased or decreased depending upon changes in the applicable  Reference.  The
terms of the structured  securities may provide that in certain circumstances no
principal  is due at  maturity  and,  therefore,  may  result in the loss of the
Fund's  investment.  Structured  securities  may  be  positively  or  negatively
indexed,  so that  appreciation  of the  Reference  may  produce an  increase or
decrease in the interest rate or value of the security at maturity. In addition,
the change in interest  rate or the value of the  security at maturity  may be a
multiple of the change in the value of the Reference.  Consequently,  structured
securities  entail a  greater  degree of market  risk than  other  types of debt
obligations.  Structured  securities may also be more volatile,  less liquid and
more difficult to accurately price than less complex fixed income investments.

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

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

                                       3
<PAGE>

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

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

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

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

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

Prepayment  rates are  influenced  by changes in  current  interest  rates and a
variety  of  economic,  geographic,  social  and  other  factors  and  cannot be
predicted with  certainty.  Both  adjustable  rate mortgage loans and fixed rate
mortgage  loans may be subject to a greater rate of principal  prepayments  in a
declining   interest  rate  environment  and  to  a  lesser  rate  of  principal
prepayments in an increasing  interest rate environment. 

                                       4
<PAGE>

Under certain interest rate and prepayment rate scenarios,  the Fund may fail to
recoup fully its investment in Mortgage-Backed  Securities  notwithstanding  any
direct  or  indirect  governmental,  agency  or other  guarantee.  When the Fund
reinvests  amounts   representing   payments  and  unscheduled   prepayments  of
principal,  it may  receive a rate of  interest  that is lower  than the rate on
existing adjustable rate mortgage pass-through securities. Thus, Mortgage-Backed
Securities,  and adjustable rate mortgage pass-through securities in particular,
may be less effective than other types of U.S. Government  securities as a means
of "locking in" interest rates.

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

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

Planned  amortization  class ("PAC") and target  amortization  class ("TAC") CMO
bonds involve less exposure to prepayment, extension and interest rate risk than
other Mortgage-Backed  Securities,  provided that prepayment rates remain within
expected  prepayment  ranges or "collars." To the extent that  prepayment  rates
remain within these prepayment  ranges,  the residual or support tranches of PAC
and TAC CMOs  assume the extra  prepayment,  extension  and  interest  rate risk
associated with the underlying mortgage assets.

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

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

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

<PAGE>

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

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

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

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

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

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

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

Mortgage  "Dollar Roll"  Transactions.  The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers  pursuant to which the
Fund sells mortgage-backed securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date.  The Fund will only enter into covered rolls. A "covered roll" is a
specific type of dollar roll for which there is an offsetting cash position or a
cash  equivalent  security  position  that  matures  on or  before  the  forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior  security and will be excluded from the  calculation
of the Fund's borrowings and other senior  securities.  For financial  reporting
and tax  purposes,  the  Fund  treats  mortgage  dollar  rolls  as two  separate
transactions;   one  involving  the  purchase  of  a  security  and  a  separate
transaction  involving a sale. The Fund does not currently  intend to enter into
mortgage dollar roll transactions that are accounted for as a financing.

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

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

Credit  card  receivables  are  generally  unsecured  and  the  debtors  on such
receivables  are  entitled  to the  protection  of a number of state and federal
consumer  credit  laws,  many of which  give such  debtors  the right to set-off
certain  amounts  owed on the credit  cards,  thereby  reducing the balance due.
Automobile  receivables  generally are secured,  but by automobiles  rather than
residential  real property.  Most issuers of automobile  receivables  permit the
loan  servicers  to retain  possession  of the  underlying  obligations.  If the
servicer were to sell these  obligations to another party,  there is a risk that
the purchaser  would acquire an interest  superior to that of the holders of the
asset-backed  securities.  In addition,  because of the large number of vehicles
involved in a typical issuance and technical  requirements under state laws, the
trustee  for the  holders of the  automobile  receivables  may not have a proper
security  interest  in  the  underlying  automobiles.  Therefore,  there  is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

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

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

Swap agreements will tend to shift the Fund's investment  exposure from one type
of  investment to another.  Caps and floors have an effect  similar to buying or
writing options. Depending on how they are used, swap agreements may increase or
decrease the overall  volatility of a Fund's investments and its share price and
yield.

                                       8

Swap agreements are sophisticated  hedging  instruments that typically involve a
small  investment  of cash  relative to the  magnitude  of risks  assumed.  As a
result,  swaps can be highly volatile and may have a considerable  impact on the
Fund's  performance.  Swap  agreements  are  subject  to  risks  related  to the
counterparty's   ability  to   perform,   and  may   decline  in  value  if  the
counterparty's creditworthiness deteriorates. The Fund may also suffer losses if
it is unable to terminate  outstanding  swap  agreements  or reduce its exposure
through offsetting transactions.  The Fund will maintain in a segregated account
with its custodian,  cash or liquid  securities equal to the net amount, if any,
of the excess of the Fund's  obligations over its  entitlements  with respect to
swap, cap, collar or floor transactions.

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

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

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

Short-Term Trading and Portfolio Turnover. Short-term trading means the purchase
and subsequent sale of a security after it has been held for a relatively  brief
period of time.  The Fund does not invest for the purpose of seeking  short-term
profits.  The Fund's  investment  securities  may be changed,  however,  without
regard to the  holding  period  of these  securities  (subject  to  certain  tax
restrictions),  when the Adviser  deems that this  action will help  achieve the
Fund's objective given a change in an issuer's  operations or changes in general
market  conditions.  Short-term  trading  may  have  the  effect  of  increasing
portfolio  turnover  rate. A high rate of portfolio  turnover  (100% or greater)
involves  correspondingly  greater  expenses.  The Fund's  portfolio rate is set
forth in the table under the caption "Financial Highlights" in the Prospectus.

INVESTMENT RESTRICTIONS

Fundamental Investment Restrictions.  The following investment restrictions will
not be changed  without 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, except that as a temporary measure for extraordinary
         or emergency purposes the Fund may borrow from banks in aggregate
         amounts at any one time outstanding not exceeding 33 1/3% of the total
         assets (including the amount borrowed) of the Fund valued at market;
         and the Fund may not purchase any securities at any time when
         borrowings exceed 5% of the total assets of the Fund (taken at market
         value). This borrowing restriction does not prohibit the use of reverse
         repurchase agreements (see "Reverse Repurchase Agreements"). For
         purposes of this investment restriction, forward commitment
         transactions shall not constitute borrowings. Interest paid on any
         borrowings will reduce the Fund's net investment income;

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

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

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

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

                                       10
<PAGE>

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

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

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

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

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

The Fund may not:

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

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

(c)      invest in  commodities,  except  that the Fund may  purchase  and sell:
         forward commitments,  when-issued  securities,  securities index put or
         call  warrants,  repurchase  agreements,   options  on  securities  and
         securities  indices,  futures  contracts on securities  and  securities
         indices and options on these futures,  entered into in accordance  with
         the Fund's  investment  policies (the Fund does not currently intend to
         invest in options and futures);

                                       11
<PAGE>

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

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

THOSE RESPONSIBLE FOR MANAGEMENT

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

INVESTMENT ADVISORY AND OTHER SERVICES

The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts 02199-7603,
was  organized in 1968 and has more than $30 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 a high  rating  from  Standard & Poor's and A.M.
Best.  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 but not
limited to  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,
maintaining a committed line of credit,  and  calculating the net asset value of
shares;  fees and expenses of transfer  agents and dividend  disbursing  agents;
legal, accounting,  financial, management, tax and auditing fees and expenses of
the Fund (including an allocable portion of the cost of the Adviser's  employees
rendering such services to the Fund);  the compensation and expenses of Trustees
who are not  otherwise  affiliated  with the Trust,  the Adviser or any of their
affiliates;  expenses of Trustees' and shareholders' meetings; trade association
memberships; insurance premiums; and any extraordinary expenses.
    

As compensation for its services under the Advisory Agreement, the Fund pays the
Adviser monthly a fee based on a stated percentage,  equal on an annual basis to
0.40%, of the average daily net assets of the Fund.

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

                                       21
<PAGE>

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

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

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

   
Under the Fund's master/feeder  structure (which was terminated on September 22,
1995 pursuant to an Agreement and Plan of Liquidation and Termination dated June
13,  1995)  existing  for the fiscal  years ended March 31, 1995 and 1996 (until
September  22, 1995),  the Fund  invested all of its assets in  Adjustable  U.S.
Government Fund (the "Portfolio").  During these years, advisory fees payable by
the Portfolio to Transamercia Fund Management Company ("TFMC'),  the Portfolio's
former  investment  adviser,  and  borne  indirectly  by the Fund,  amounted  to
$107,596 and $0, respectively.  For the fiscal years ended March 31, 1995, 1996,
1997, for the period April 1, 1997 to May 31, 1997 and for the fiscal year ended
May 31,  1998,  advisory  fees paid by the  Portfolio  to the  Adviser and borne
indirectly by the Fund,  amounted to $35,865,  $137,927,  $132,601,  $19,526 and
$412,737,  respectively.  For the years ended March 31, 1995, 1996, 1997 and for
the period  April 1, 1997 to May 31, 1997 TFMC (until  December 22,  1994),  the
Adviser received fees of $0, $0, $10,548 and $0, respectively.

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
majority of the  Trustees who are not parties to the  Agreement  or  "interested
persons" of any such  parties.  Both  agreements  may be  terminated  on 60 days
written notice by any party or by a vote of a majority of the outstanding voting
securities of the Fund and will terminate automatically if assigned.

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

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

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

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

For the fiscal year ended March 31, 1995, the Fund paid to TFMC (pursuant to the
Services  Agreement) $9,604 of which $8,164 was paid to TFMC and $1,440 was paid
for certain data processing and pricing information services.

For the fiscal year ended March 31, 1995,  the Portfolio  paid TFMC (pursuant to
the Services Agreement) $24,461 of which $17,704 was paid to TFMC and $6,757 was
paid for certain data processing and pricing information services.

   
Accounting and Legal Services Agreement.  The Trust, on behalf of the Fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this Agreement,  the Adviser  provides the Fund with certain tax,  accounting
and legal services.  For the period from April 1, 1997 to May 31, 1997, the Fund
paid the Adviser $915 for services under this Agreement. From the effective date
of July 1, 1996 to March 31, 1997,  the Fund paid the Adviser  $4,508 under this
agreement.  For the fiscal year ended May 31, 1998, the Fund paid to the Adviser
$18,259 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 on behalf of the Fund.  Shares of the Fund are also sold by
selected  broker-dealers (the "Selling Brokers") which have entered into selling
agency agreements with John Hancock Funds. John Hancock Funds accepts orders for
the purchase of the shares of the Fund that are continually offered at net asset
value next determined,  plus any applicable sales charge,  if any. In connection
with the sale of 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 shares,  the broker  receives  compensation
immediately but John Hancock Funds is compensated on a deferred basis.
    

Total  underwriting  commissions  for sales of the Fund's Class A shares for the
fiscal   years  ended  March  31,  1996  and  1997  were  $4,976  and   $26,470,
respectively,  for the  period  from  April 1, 1997 to May 31,  1997 and for the
fiscal year ended May 31, 1998 were $7,357 and  $96,964,  respectively.  Of such
amounts,  $0,  $6,000,  $557 and $13,316,  respectively,  were  retained by John
Hancock Funds in 1996,  1997,  for the period from April 1, 1997 to May 31, 1997
and for the fiscal year ended May 31, 1998.  The  remainder of the  underwriting
commissions were reallowed to Selling Brokers.

   
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
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  average
daily net assets  attributable to each class of shares.  The  distribution  fees
will be used to reimburse the John Hancock Funds for its distribution  expenses,
including  but not limited to: (i) initial  and ongoing  sales  compensation  to
Selling  Brokers and others  (including  affiliates  of the John Hancock  Funds)
engaged in the sale of Fund shares;  (ii)  marketing,  promotional  and overhead
expenses incurred in connection with the distribution of Fund shares;  and (iii)
with  respect  to  Class  B  shares  only,  interest  expenses  on  unreimbursed
distribution  expenses.  The  service  fees will be used to  compensate  Selling
Brokers and others for providing  personal and account  maintenance  services to
shareholders.  In the event that John Hancock Funds is not fully  reimbursed for
payments or expenses under the Class A Plan,  these expenses will not be carried
beyond twelve  months from the date they were  incurred.  Unreimbursed  expenses
under the Class B Plan will be carried  forward  together  with  interest on the
balance of these  unreimbursed  expenses.  The Fund does not treat  unreimbursed
expenses under the Class B Plan as a liability of the Fund, because the Trustees
may  terminate  the Class B Plan at any time.  For the fiscal year ended May 31,
1998, an aggregate of $626,536 of distribution  expenses or 5.48% of the average
net assets of the Class B shares of the Fund, was not reimbursed or recovered by
the John Hancock  Funds  through the receipt of deferred  sales charges or 12b-1
fees in prior periods.

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

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

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

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

During the fiscal year ended May 31, 1998,  the Fund paid John Hancock Funds the
following amounts of expenses in connection with their services for the Fund:

SALES COMPENSATION

As part of their business strategies, each of the John Hancock 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.  The sales charges and 12b-1
fees paid by investors are detailed in the  prospectus  and under  "Distribution
Contracts" in this  Statement of Additional  Information.  The portions of these
expenses  that are reallowed to financial  services  firms are shown on the next
page.
    

Whenever  you make an  investment  in the  fund,  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.  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.

calculated   from  different   amounts,   and  therefore  may  not  equal  total
compensation percentages if combined using simple addition.

CDSC  revenues  collected by John Hancock  Funds may be used to pay  commissions
when there is no initial sales charge.

NET ASSET VALUE

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

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

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

                                       27
<PAGE>

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

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

INITIAL SALES CHARGE ON CLASS A SHARES

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

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

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

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

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

                                       28
<PAGE>

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

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

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

o        Retirement  plans  investing   through  the  PruArray  Program
         sponsored by Prudential Securities.

   
o        Pension  plans  transferring  assets from a John Hancock variable
         annuity  contract  to the Fund  pursuant  to an  exemptive  application
         approved by the Securities Exchange Commission.
    

o        Existing full service clients of the Life Company who were group
         annuity  contract  holders as of  September  1, 1994,  and  participant
         directed  retirement plans with at least 100 eligible  employees at the
         inception of the Fund  account.  Each of these  investors  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.

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 being  invested but also
the investor's 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. Retirement plan investors may include the value of Class
B shares if Class B shares held are greater  than $1 million.  Retirement  plans
must notify Signature Services to utilize.

                                       29
<PAGE>

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

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

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

DEFERRED SALES CHARGE ON CLASS B SHARES

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

                                       30
<PAGE>

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

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

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

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

When requesting a redemption for a specific dollar amount please indicate if you
require the proceeds to equal the dollar  amount  requested.  If not  indicated,
only the  specified  dollar  amount will be redeemed  from your  account and the
proceeds will be less any applicable CDSC.

Example:

You have  purchased  100  shares at $10 per share.  The  second  year after your
purchase,  your  investment's  net asset value per share has  increased by $2 to
$12, and you have gained 10 additional shares through dividend reinvestment.  If
you redeem 50 shares at this time your CDSC will be calculated as follows:

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

                                                                       --------
 o   Amount subject to CDSC                                            $ 280.00

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

Proceeds  from the CDSC are paid to John Hancock  Funds and are used in whole or
in part by John  Hancock  Funds to defray  its  expenses  related  to  providing
distribution-related  services  to the Fund in  connection  with the sale of the
Class B shares,  such as the payment of  compensation  to select Selling Brokers
for selling Class B shares. The combination of the CDSC and the distribution and
service  fees  facilitates  the  ability  of the Fund to sell the Class B shares
without a sales charge being deducted at the time of the purchase.

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

                                       34

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.  Since the redemption price of the Fund shares may be
more or less than the shareholder's cost, depending upon the market value of the
securities owned by the Fund at the time of redemption, the distribution of cash
pursuant to this plan may result in  realization of gain or loss for purposes of

                                       35
<PAGE>

Federal,  state  and  local  income  taxes.  The  maintenance  of  a  Systematic
Withdrawal  Plan  concurrently  with purchases of additional  Class A or Class B
shares of the Fund  could be  disadvantageous  to a  shareholder  because of the
initial  sales charge  payable on such  purchases of Class A shares and the CDSC
imposed on  redemptions  of Class B shares and because  redemptions  are taxable
events.  Therefore, a shareholder should not purchase Class A and Class B shares
at the same time a Systematic  Withdrawal  Plan is in effect.  The Fund reserves
the  right to  modify  or  discontinue  the  Systematic  Withdrawal  Plan of any
shareholder  on  30  days  prior  written  notice  to  such  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 order date of any investment.
    

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

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

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

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

Retirement plans participating in Merrill Lynch's servicing programs:

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

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

DESCRIPTION OF THE FUND'S SHARES

The Trustees of the Trust are  responsible for the management and supervision of
the Fund.  The  Declaration  of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of the Fund, without
par value.  Under the  Declaration of Trust,  the Trustees have the authority to
create and classify shares of beneficial  interest in separate  series,  without
further action by  shareholders.  As of the date of this Statement of Additional
Information,  the Trust has two Funds and only one series and the Trustees  have
not authorized any additional series of the Fund, although they may do so in the
future.  The  Declaration of Trust also  authorizes the Trustees to classify and
reclassify  the  shares of the Fund,  or any new series of the Trust into one or
more classes.  As of the date of this Statement of Additional  Information,  the
Trustees  have  authorized  the  issuance  of two classes of shares of the Fund,
designated as Class A and Class B.

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

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

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

Unless  otherwise  required by the Investment  Company Act or the Declaration of
Trust,  the Fund has no intention of holding  annual  meetings of  shareholders.
Fund  shareholders  may  remove a Trustee  by the  affirmative  vote of at least
two-thirds of the Trust's  outstanding  shares and the Trustees  shall  promptly
call a meeting for such purpose when requested to do so in writing by the record

                                       37
<PAGE>

holders  of  not  less  than  10%  of  the  outstanding  shares  of  the  Trust.
Shareholders   may,  under  certain   circumstances,   communicate   with  other
shareholders in connection  with  requesting a special meeting of  shareholders.
However,  at any time that less than a majority of the Trustees  holding  office
were elected by the  shareholders,  the Trustees will call a special  meeting of
shareholders for the purpose of electing Trustees. 

Under Massachusetts law,  shareholders of a Massachusetts  business trust could,
under certain  circumstances,  be held personally liable for acts or obligations
of the Trust.  However,  the Declaration of Trust contains an express disclaimer
of  shareholder  liability  for acts,  obligations  or affairs of the Fund.  The
Declaration of Trust also provides for  indemnification out of the Fund's assets
for all losses and expenses of any shareholder held personally  liable by reason
of being or having been a  shareholder.  The  Declaration of Trust also provides
that no series of the Trust  shall be liable  for the  liabilities  of any other
series.  Furthermore, no fund included in this Fund's prospectus shall be liable
for the  liabilities  of any other John  Hancock  Fund.  Liability  is therefore
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  starter,  credit card or third party checks.  All
checks  returned by the post office as  undeliverable  will be reinvested at net
asset  value in the fund or funds from which a  redemption  was made or dividend
paid. 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. For telephone transactions, the transfer agent 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,  the transfer agent 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.
    

TAX STATUS

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

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


   
Distributions  from the  Fund's  current or  accumulated  earnings  and  profits
("E&P") will be taxable  under the Code for investors who are subject to tax. If

                                       38
<PAGE>

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

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

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

   
Upon a  redemption  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.  This disregarded  charge will result in an
increase in the  shareholder's  tax basis in the shares  subsequently  acquired.
Also,  any loss  realized on a redemption  or exchange may be  disallowed to the
extent the shares  disposed of are replaced with other shares of the Fund within
a period of 61 days beginning 30 days before and ending 30 days after the shares
are disposed of, such as pursuant to automatic dividend reinvestments. In such a
case,  the  basis  of the  shares  acquired  will be  adjusted  to  reflect  the
disallowed  loss.  Any loss  realized  upon the  redemption of shares with a tax
holding period of six months or less will be treated as a long-term capital loss
to the extent of any amounts treated as distributions of long-term  capital gain
with respect to such shares.  Shareholders should consult their own tax advisers
regarding their particular  circumstances to determine  whether a disposition of
Fund shares is properly treated as a sale for tax purposes, as is assumed in the
foregoing discussion.
    
                                       39
<PAGE>

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 own net capital gains, if any, during the
eight years following the year of the loss. To the extent subsequent net capital
gains are offset by such  losses,  they  would not result in Federal  income tax
liability to the Fund and, as noted above,  would not be  distributed as such to
shareholders. The Fund has $17,040,448 of capital loss carryforwards,  available
to the extent provided by regulations,  as to offset future net realized capital
gains. These carryforwards expire at various amounts and times from 1999 through
2005.
    

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

The Fund is required to accrue income on any debt securities that have more than
a de minimis amount of original issue discount (or debt securities acquired at a
market  discount,  if the Fund  elects  to  include  market  discount  in income
currently) prior to the receipt of the corresponding cash payments. However, the
Fund must distribute to shareholders for each taxable year  substantially all of
its net income,  including  such  income,  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 intangibles property taxes, the
value of its assets is  attributable  to) certain U.S.  Government  obligations,
provided in some states that certain thresholds for holdings of such obligations
and/or reporting  requirements are satisfied.  The Fund will not seek to satisfy
any  threshold or reporting  requirements  that may apply in  particular  taxing
jurisdictions,  although the Fund may in its sole  discretion  provide  relevant
information to shareholders.

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

                                       40
<PAGE>

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

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

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

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

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

The Fund is not subject to  Massachusetts  corporate  excise or franchise taxes.
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

   
For the 30-day fiscal period ended May 31, 1998,  the  annualized  yield for the
Fund's  Class A and Class B shares  were  4.76%  and  4.16%,  respectively.  The
average  annual  return for the Fund's Class A and Class B shares for the period
from  December 31, 1991  (inception of the Fund) through May 31, 1998 were 5.71%
and 4.96%,  respectively.  For the one year fiscal year ended May 31, 1998,  the
average  annual  returns were 6.27% and 5.74%,  respectively.  For the five year
period  ended May 31,  1998,  the average  annual  returns were 4.88% and 4.81%,
respectively.
    
                                       41
<PAGE>

The  Fund's  yield is  computed  by  dividing  net  investment  income per share
determined  for a 30-day period by the maximum  offering  price per share (which
includes the full sales charge, where applicable) on the last day of the period,
according to the following standard formula:
                  
                                                     6
                        Yield = 2 ( [ (a - b) + 1 ]   - 1
                                       -----
                                        cd          

Where:

a =      dividends and interest earned during the period.
b =      net expenses accrued during the period.
c =      the average  daily  number of fund shares  outstanding  during the
         period that would be entitled to receive dividends.
d =      the  maximum  offering  price per share on the last day of the  period
         (NAV where applicable).

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

                                     n _____
                                T = \ /ERV/P - 1
                           

Where:

P =      a hypothetical initial investment of $1,000.
T =      average annual total return
n =      number of years
ERV=     ending redeemable value of a hypothetical $1,000 investment made at
         designated periods or fraction thereof.

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

                                       42
<PAGE>

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

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

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

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

BROKERAGE ALLOCATION

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

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

                                       43
<PAGE>

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

To the extent  consistent  with the foregoing,  the Fund will be governed in the
selection of brokers and dealers,  and the  negotiation of brokerage  commission
rates and dealer  spreads,  by the  reliability  and  quality  of the  services,
including primarily the availability and value of research  information and to a
lesser extent statistical  assistance  furnished to the Adviser of the Fund, and
their value and expected  contribution to the performance of the Fund. It is not
possible to place a dollar value on information and services to be received from
brokers and dealers,  since it is only  supplementary to the research efforts of
the  Adviser.  The receipt of  research  information  is not  expected to reduce
significantly  the  expenses  of  the  Adviser.  The  research  information  and
statistical  assistance  furnished  by brokers  and dealers may benefit the Life
Company or other  advisory  clients of the Adviser,  and  conversely,  brokerage
commissions and spreads paid by other advisory clients of the Adviser may result
in research information and statistical  assistance  beneficial to the Fund. The
Fund will not make any commitment to allocate  portfolio  transactions  upon any
prescribed basis. While the Adviser's officers will be primarily responsible for
the  allocation of the Fund's  brokerage  business,  the policies in this regard
must be consistent with the foregoing and will at all times be subject to review
by the  Trustees.  For the years ended March 31,  1997 and 1996,  no  negotiated
brokerage commissions were paid on portfolio  transactions.  For the period from
April 1, 1997 to May 31,  1997 and for the fiscal  year ended May 31,  1998,  no
negotiated brokerage commissions were paid on portfolio transactions.

As permitted by Section 28(e) of the  Securities  Exchange Act of 1934, the Fund
may pay to a broker which provides  brokerage and research  services to the Fund
an amount of disclosed  commission  in excess of the  commission  which  another
broker would have  charged for  effecting  that  transaction.  This  practice is
subject  to a good  faith  determination  by the  Trustees  that  such  price is
reasonable  in  light  of the  services  provided  and to such  policies  as the
Trustees may adopt from time to time. During the fiscal year ended May 31, 1998,
the Fund did not pay commissions to compensate any brokers for research services
such as industry, economic and company reviews and evaluations of securities.

The  Adviser's  indirect  parent,  the  Life  Company,   is  the  indirect  sole
shareholder of John Hancock Distributors,  Inc., a broker-dealer ("Distributors"
or "Affiliated  Broker").  Pursuant to procedures determined by the Trustees and
consistent  with the above  policy of obtaining  best net results,  the Fund may
execute portfolio  transactions with or through Affiliated  Brokers.  During the
years  ended March 31,  1997 and 1996,  the Fund did not  execute any  portfolio
transactions  with any Affiliated  Broker.  For the period from April 1, 1997 to
May 31,  1997 and for the  fiscal  year  ended  May 31,  1998,  the Fund did not
execute any portfolio transactions with any Affiliated Broker.

Distributors may act as broker for the Fund on exchange  transactions,  subject,
however,  to the general  policy of the Fund set forth above and the  procedures
adopted by the Trustees pursuant to the Investment Company Act. Commissions paid
to an  Affiliated  Broker  must be at least as  favorable  as  those  which  the
Trustees believe to be contemporaneously  charged by other brokers in connection
with comparable  transactions  involving  similar  securities being purchased or
sold.
                                       44
<PAGE>

A transaction would not be placed with an Affiliated Broker if the Fund would
have to pay a commission rate less favorable than the Affiliated Broker's
contemporaneous charges for comparable transactions for its other most favored,
but unaffiliated, customers, except for accounts for which the Affiliated Broker
acts as a clearing broker for another brokerage firm, and any customers of the
Affiliated Broker not comparable to the Fund as determined by a majority of the
Trustees who are not interested persons (as defined in the Investment Company
Act) of the Fund, the Adviser or the Affiliated Broker. Because the Adviser,
which is affiliated with the Affiliated Brokers, has, as an investment adviser
to the Fund, the obligation to provide investment management services, which
includes elements of research and related investment skills, such research and
related skills will not be used by the Affiliated Broker as a basis for
negotiating commissions at a rate higher than that determined in accordance with
the above criteria.

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

TRANSFER AGENT SERVICES

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

CUSTODY OF PORTFOLIO

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

INDEPENDENT AUDITORS

APPENDIX-A

MORE ABOUT RISK

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

A fund is 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 the fund utilizes these
securities  or  practices,  its  overall  performance  may be  affected,  either
positively  or  negatively.  On the  following  pages are brief  definitions  of
certain  associated  risks with them,  with examples of related  securities  and
investment  practices included in brackets.  See the "Investment  Objectives and
Policies" and "Investment Restrictions" sections of this Statement of Additional
Information  for a  description  of this Fund's  investment  policies.  The fund
follows certain policies that may reduce these risks.

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

TYPES OF INVESTMENT RISK

Correlation risk The risk that changes in the value of a hedging instrument will
not match those of the asset being hedged  (hedging is the use of one investment
to offset the effects of another investment).  Incomplete correlation can result
in unanticipated risks. (e.g., currency contracts,  futures and related options,
options on securities and indices, swaps, caps, floors and collars).

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.  (e.g., non-  investment-grade debt securities,  borrowing;  reverse
repurchase  agreements,  covered mortgage dollar roll  transactions,  repurchase
agreements,  securities lending, brady bonds, foreign debt securities,  in-kind,
delayed   and   zero   coupon   debt   securities,    asset-backed   securities,
mortgage-backed  securities,  participation  interest,  options  on  securities,
structured securities and swaps, caps floors and collars).

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.(e.g.,  foreign debt
securities, currency contracts, swaps, caps, floors and collars).

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

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.  (e.g.,
non-investment-grade debt securities, covered mortgage dollar roll transactions,
brady bonds,  foreign  debt  securities,  in-kind,  delayed and zero coupon debt
securities, asset-backed securities,  mortgage-backed securities,  participation
interest, swaps, caps, floors and collars).

Leverage risk  Associated  with securities or practices (such as borrowing) that
multiply  small index or market  movements  into large  changes in value.  (e.g.
borrowing;   reverse  repurchase   agreements,   covered  mortgage  dollar  roll
transactions,   when-issued   securities  and  forward   commitments,   currency
contracts,   financial  futures  and  options;  securities  and  index  options,
structured securities, swaps, caps, floors and collars).

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.

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. (e.g. non-investment-grade debt securities, restricted and illiquid
securities,   mortgage-backed   securities,   participation  interest,  currency
contracts, futures and related options; securities and index options, structured
securities, swaps, caps, floors and collars).

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

Market risk The risk that the market  value of a security  may move up and down,
sometimes rapidly and unpredictably.  Market risk may affect a single issuer, an
industry,  a sector of the bond  market or the market as a whole.  Common to all
stocks  and bonds and the  mutual  funds  that  invest  in them.  (e.g.  covered
mortgage dollar roll transactions,  short-term trading,  when-issued  securities
and forward commitments, brady bonds, foreign debt securities,  in-kind, delayed
and zero coupon debt securities,  restricted and illiquid securities, rights and
warrants,  financial  futures and options;  and  securities  and index  options,
structured securities).

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.(e.g.   covered  mortgage  dollar  roll  transactions,   when-issued
securities and forward  commitments,  currency contracts,  financial futures and
options; securities and securities and index options).

Political  risk The risk of  losses  attributable  to  government  or  political
actions, from changes in tax or trade statutes to governmental collapse and war.
(e.g., brady bonds and foreign debt securities).

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

Valuation  risk The risk that a fund has valued  certain of its  securities at a
higher  price  than it can  sell  them  for.  (e.g.,  non-investment-grade  debt
securities,  participation interest,  structured securities, swaps, caps, floors
and collars).

APPENDIX B


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

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

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

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

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

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

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

                                      B-1
<PAGE>

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

Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principle or
interest.

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

C:  Bonds  which are rated C are the lowest  rated  class of bonds and issues so
rated can be regarded as having  extremely  poor prospects of ever attaining any
real investment standing.

Standard & Poor's Ratings Group

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

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

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

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

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

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

                                     PART C.

                               OTHER INFORMATION

Item. 23.   Exhibits:

The  exhibits to this  Registration  Statement  are listed in the Exhibit  Index
hereto and are incorporated herein by reference.

Item 24.   Persons Controlled by or under Common Control with Registrant.

No person is directly or indirectly  controlled by or under common  control with
Registrant.

Item. 25.  Indemnification.

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

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

Section 9(a) of the By-Laws of John Hancock Mutual Life Insurance  Company ("the
Insurance  Company")  provides,  in effect,  that the  Insurance  Company  will,
subject to  limitations  of law,  indemnify  each  present and former  director,
officer and employee of the 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 final
adjudication  unless  such  settlement  shall have been  approved as in the best
interests of the Insurance Company either by vote of the Board of Directors at a
meeting  composed of directors who have no interest in the outcome of such vote,
or by vote of the policyholders. The Insurance Company may pay expenses incurred
in  defending an action or claim in advance of its final  disposition,  but only
upon receipt of an undertaking  by the person  indemnified to repay such payment
if he should be determined not to be entitled to indemnification.

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

                                      C-1

<PAGE>

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

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

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

Item 26.  Business and Other Connections of Investment Advisers.

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

Item 27.  Principal Underwriters.

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