Real Estate Fund

Goal and Strategy

[Clip Art] The fund seeks long-term growth of capital. Income is a secondary
goal. In pursuing these goals, the fund invests at least 65% of assets in
securities of real estate companies. These include U.S. and foreign companies
whose businesses are focused on owning, managing or marketing real estate;
companies in related industries, such as financing or construction; and
companies in other businesses that may have substantial real estate holdings.
Securities may include stocks, bonds and other equity and debt securities of any
maturity, such as mortgage-related debt securities.

The fund may invest up to 20% of assets in junk bonds rated as low as BB and
their unrated equivalents, and up to 15% of assets in foreign securities. The
fund may invest up to 35% of assets in securities of issuers that are not
considered real estate companies.

The fund generally focuses on shares of real estate investment trusts (REITs),
that seek to make money by investing in real estate and/or mortgages. The fund
invests in companies that are considered fundamentally undervalued due to
changing economic conditions, regional economic factors and/or industry
consolidation.

At different times, the fund may emphasize different types of securities or
issuers, depending on its outlook for interest rates, real estate prices and
other factors.

The fund may use certain derivatives (securities whose value is based on
indices, securities or currencies), especially in managing its exposure to
interest rate risk. However, 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 and other cases, the
fund might not achieve its goal.

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

PAST PERFORMANCE


[Clip Art]This section normally shows how the fund's total return has varied
from year to year, along with a broad-based market index for reference. Because
the fund is less than a year old, there is not a full year of performance to
report.

Main Risks

[Clip Art]Any adverse conditions in the real estate market could cause the fund
to lose money or underperform other funds that are diversified across sectors.
This could also happen when real estate is out of favor with investors or when
certain investments don't perform as the management team expects.

Real estate risks can be local, national or global. Possible factors range from
economic downturns and government actions to overbuilding, natural disasters,
environmental costs, changing property values, high vacancy rates, legal actions
and casualty losses.

Because they are securities, REITs can fall in value when securities markets
fall. There is also the risk that a REIT's value could fall if it is mismanaged,
faces high tenant default risk or is in danger of failing to meet certain IRS
standards. The fund could lose money on its bond investments if interest rates
rise or if any bonds it owns are downgraded in credit rating or go into default.
In general, lower-rated bonds have higher credit risks and longer maturity will
increase volatility. Some REITs may carry interest rate and credit risks as
well.

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

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

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

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.

Investments in the fund are not bank deposits and are not insured or guaranteed
by the FDIC or any other government agency. You could lose money by investing in
this fund.

YOUR EXPENSES

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

annual return was 5%. The example is for comparison only, and does not represent
the fund's actual expenses and returns, either past or future.

CHOOSING A SHARE CLASS


Each share class has its own cost structure, including a Rule 12b-1 plan that
allows it to pay fees for the sale, distribution and service of its shares. Your
financial representative can help you decide which share class is best for you.


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

o Front-end sales charges, as described at right.

o Distribution and service (12b-1) fees of 0.30%.

- --------------------------------------------------------------------------------
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 eight years, thus reducing future
  annual expenses.


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

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 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.

Investors purchasing $1 million or more of Class B or Class C shares may want to
consider the lower operating expenses of Class A shares.


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

Class A Sales charges are as follows:

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

$250,000 - $499,000                         2.50%              2.56%
$500,000 - $999,999                         2.00%              2.04%
$1,000,000 and over                         See  below

Investments of $1 million or more Class A shares are available with no front-end
sales charge. However, there is a contingent deferred sales charge (CDSC) on any
shares sold within one year of purchase, as follows:

- --------------------------------------------------------------------------------
CDSC on $1 million+ investments
- --------------------------------------------------------------------------------
Your investment                                              CDSC on shares
                                                             being sold
First $1M - $4,999,999                                       1.00%
Next $1 - $5M above that                                     0.50%
Next $1 or more above that                                   0.25%

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

6 YOUR ACCOUNT
<PAGE>



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 table below. There is no CDSC on shares
acquired through reinvestment of dividends. The CDSC is based on the original
purchase cost or the current market value of the shares being sold, whichever is
less. The CDSCs are as follows:


- --------------------------------------------------------------------------------
Class B deferred charges
- --------------------------------------------------------------------------------

Years after purchase                    CDSC on shares being sold

1st year                                5.00%
2nd year                                4.00%
3rd or 4th year                         3.00%
5th year                                2.00%
6th year                                1.00%
After 6th year                          none


- --------------------------------------------------------------------------------
Class C deferred charges
- --------------------------------------------------------------------------------

Years after purchase                    CDSC on shares being sold

1st year                                1.00%
After 1st 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 the prospectus).

CDSC waivers As long as Signature Services is notified at the time you sell, the
CDSC for each share class will generally be waived in the following cases:

o to make payments through certain systematic withdrawal plans

o to make certain distributions from a retirement plan

o because of shareholder death or disability



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

                                                                  YOUR ACCOUNT 7
<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

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, unless they were previously provided to Signature Services and are
still accurate. These items are 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 the fund and each
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 fund uses market prices
in valuing portfolio securities, but may use fair-value estimates if reliable
market prices are unavailable. The fund may trade foreign stock or other
portfolio securities on U.S. holidays and weekends, even though the fund's
shares will not be priced on those days. This may change the fund's NAV on days
when you cannot buy or sell shares.


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 The 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 Signature Services receives your
request in good order.

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, the 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 and Class
C shares will continue to age from the original date and will retain the same
CDSC rate as they had before the exchange, except that the rate will change to
the new fund's rate if that rate is higher. A CDSC rate that has increased will
drop again with a future exchange into a fund with a lower rate.


To protect the interests of other investors in the fund, the 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. The fund may also refuse any exchange
order. The 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 fund generally distributes most or all of its net earnings in the
form of dividends. The fund seeks to pay income dividends quarterly. Capital
gains dividends, if any, are typically paid annually.

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

12 YOUR ACCOUNT
<PAGE>


Taxability of dividends Dividends you receive from a fund, whether reinvested or
taken as cash, are generally considered taxable. Dividends from the fund's long-
term capital gains are taxable as capital gains; dividends from other sources
are generally taxable as ordinary income. Whether gains are short-term or
long-term depends on the fund's holding period. 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 fund's service providers are taking
steps to address any year 2000-related computer problems. However, there is some
risk that these problems could disrupt the issuers in which the fund invests,
the fund's 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.

will achieve its investment objective.


The investment objective of the Fund is to seek long-term growth of capital with
income as a  secondary  objective.  To pursue  this goal,  the Fund will  invest
primarily in equity securities of real estate companies.  The Fund's investments
will be subject to the market  fluctuation and risks inherent in all securities.
The  investment   objective  is  non-fundamental  and  may  be  changed  without
shareholder approval.


Although  the Fund will not make a practice of  short-term  trading,  securities
held for a short  time may be sold when  necessary  to  achieve  the  investment
objectives of the Fund.

The Fund will invest in shares of real estate investment trusts ("REITs"). REITs
pool investors'  funds for investment  primarily in income producing real estate
or real  estate  related  loans or  interests.  A REIT is not  taxed  on  income
distributed to shareholders if it complies with various requirements relating to
its  organization,  ownership,  assets,  income  and  distributions.  REITs  can
generally be classified as Equity REITs, Mortgage REITs and Hybrid REITs. Equity
REITs invest the majority of their assets  directly in real  property and derive
their income  primarily from rents.  Equity REITs can also realize capital gains
by selling  property that has  appreciated  in value.  Mortgage REITs invest the
majority  of their  assets in real  estate  mortgages  and derive  their  income
primarily from interest  payments.  Hybrid REITs combine the  characteristics of
both Equity REITs and Mortgage REITs.

Risks of Investment in Real Estate Securities.  The Fund will not invest in real
estate  directly,  but  only in  securities  issued  by real  estate  companies.
However,  the Fund may be subject to risks similar to those  associated with the
direct  ownership  of real estate (in  addition  to  securities  markets  risks)
because of its policy of  concentration  in the  securities  of companies in the
real estate industry.  These include declines in the value of real estate, risks
related to general  and local  economic  conditions,  dependency  on  management
skill,  heavy cash flow  dependency,  possible lack of  availability of mortgage
funds,  overbuilding,  extended vacancies of properties,  increased competition,
increases  in property  taxes and  operating  expenses,  changes in zoning laws,
losses due to costs  resulting  from the  clean-up  of  environmental  problems,
casualty or condemnation  losses,  limitations on rents, changes in neighborhood
values and the appeal of properties to tenants and changes in interest rates.

In addition to these risks, Equity REITs may be affected by changes in the value
of the  underlying  property  owned by the trusts,  while  Mortgage REITs may be
affected by the quality of any credit  extended.  Further,  Equity and  Mortgage
REITs are dependent upon management skills and generally may not be diversified.
Equity  and  Mortgage  REITs are also  subject  to heavy  cash flow  dependency,
defaults by borrowers  and  self-liquidation.  In addition,  Equity and Mortgage
REITs could possibly fail to qualify for tax free  pass-through  of income under
the Internal Revenue Code of 1986, as amended (the "Code"), or to maintain their
exemptions from registration under the Investment Company Act of 1940 (the "1940
Act").  The above factors may also  adversely  affect a borrower's or a lessee's
ability  to meet its  obligations  to the REIT.  In the event of a default  by a
borrower or lessee,  the REIT may experience delays in enforcing its rights as a
mortgagee or lessor and may incur  substantial  costs associated with protecting
its investments.

Risks of Investment in Foreign Securities.  The Fund may invest up to 15% of its
total  assets in  securities  of foreign  real estate  companies.  Investing  in
securities issued by foreign corporations  involves  considerations and possible
risks not typically  associated with investing in securities  issued by domestic
corporations.  The  values of foreign  investments  are  affected  by changes in
currency rates or exchange control regulations, application of foreign tax laws,
including withholding taxes, changes in governmental  administration or economic
or monetary policy (in the United States or abroad) or changed  circumstances in
dealings  between  nations.  Costs are incurred in connection  with  conversions
between  various  currencies.  In addition,  foreign  brokerage  commissions are
generally higher than in the United States,  and foreign  securities markets may
be less liquid, more volatile and less subject to governmental  supervision than
in the United  States.  Investments  in foreign  countries  could be affected by
other  factors  not  present  in the  United  States,  including  expropriation,
confiscatory  taxation,  lack of uniform  accounting and auditing  standards and
potential difficulties in enforcing contractual obligations and could be subject
to extended settlement periods.

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

Lower Rated High Yield "High Risk" Debt Obligations. The fixed-income securities
in which the Fund may invest,  may be rated as low as BB by S&P or Ba by Moody's
and  unrated  securities  of  comparable  credit  quality as  determined  by the
Adviser.  Fixed-income  securities  that are  rated  below  BBB by S&P or Baa by
Moody's indicate obligations that are speculative to a high degree and are often
in default.  Appendix A contains  further  information  concerning the rating of
Moody's and S&P and their significance.

Securities rated lower than Baa by Moody's or BBB by S&P are sometimes  referred
to as junk bonds.  See the Appendix  attached to this  Statement  of  Additional
Information which describes the characteristics of the securities in the various
ratings  categories.  The Fund is not obligated to dispose of  securities  whose
issuers   subsequently  are  in  default  or  which  are  downgraded  below  the
above-stated  ratings.  The credit  ratings of  Moody's  and S&P,  such as those
ratings  described  here,  may not be  changed  by  Moody's  and S&P in a timely
fashion to reflect subsequent  economic events. The credit ratings or securities
do not reflect an evaluation of market risk. 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

                                       3
<PAGE>


change in financial condition affecting the issuer's ability to make payments of
interest and principal. The market price and liquidity of lower rated fixed
income securities generally respond more to short-term corporate and market
developments than do those of higher rated securities, because these
developments are perceived to have a more direct relationship to the ability of
an issuer of lower rated securities to meet its on going debt obligations. The
Adviser seeks to minimize these risks through diversification, investment
analysis and attention to current developments in interest rates and economic
conditions.

Reduced  volume and  liquidity in the high yield high risk 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 high risk bonds.  In addition,  the
Fund's  investment  in high yield high risk  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 risk  inherent  in all
securities.  Increasing  rate note  securities  are typically  refinanced by the
issuers within a short period of time. The Fund may invest in pay-in-kind  (PIK)
securities,  which pay interest in either cash or additional securities,  at the
issuer's option, for a specified period. The Fund also may invest in zero coupon
bonds,  which have a determined  interest  rate,  but payment of the interest is
deferred  until  maturity  of the  bonds.  Both  types  of  bonds  may  be  more
speculative and subject to greater  fluctuations in value than securities  which
pay interest periodically and in cash, due to changes in interest rates.

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

Investment  in  Foreign  Securities.  The Fund may invest in the  securities  of
foreign  issuers in the form of sponsored and  unsponsored  American  Depository
Receipts  ("ADRs") and U.S.  dollar-denominated  securities  of foreign  issuers
traded  on U.S.  exchanges.  ADRs  (sponsored  and  unsponsored)  are  receipts,
typically  issued  by  U.S.  banks,   which  evidence  ownership  of  underlying
securities issued by a foreign  corporation.  ADRs are publicly traded on a U.S.
stock  exchange or in the  over-the-counter  market.  An  investment  in foreign
securities  including  ADRs may be affected by changes in currency  rates and in
exchange control regulations.  Issuers of unsponsored ADRs are not contractually
obligated to disclose material information including financial  information,  in
the United States and,  therefore,  there may not be a correlation  between such
information and the market value of the unsponsored ADR.  Foreign  companies may
not be subject to accounting standards or government  supervision  comparable to
U.S.  companies,  and there is often less publicly  available  information about
their  operations.  Foreign  companies  may also be  affected  by  political  or
financial  instability  abroad.  These risk considerations may be intensified in
the  case of  investments  in ADRs of  foreign  companies  that are  located  in
emerging market countries. ADRs of companies located in these countries may have
limited  marketability  and may be  subject  to more  abrupt  or  erratic  price
movements.

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

The Fund has  established a procedure  providing that the securities  serving as
collateral  for  each  repurchase  agreement  must be  delivered  to the  Fund's
custodian  either  physically or in book-entry form and that the collateral must
be marked to market  daily to ensure  that each  repurchase  agreement  is fully
collateralized  at all times.  In the event of  bankruptcy or other default by a
seller  of  a  repurchase  agreement,   the  Fund  could  experience  delays  in
liquidating the underlying securities and could experience losses, including the
possible decline in the value of the underlying  securities during the period in
which the Fund seeks to enforce its rights thereto, possible subnormal levels of
income,  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 U.S.  Government  securities  held in its
portfolio to a bank with an agreement that the Fund will buy back the securities
at a fixed  future  date at a fixed  price plus an agreed  amount of  "interest"
which may be reflected in the repurchase price.  Reverse  repurchase  agreements
are  considered  to be  borrowings by the Fund.  Reverse  repurchase  agreements
involve the risk that the market value of securities  purchased by the Fund with
proceeds  of the  transaction  may  decline  below the  repurchase  price of the
securities  sold by the Fund which it is obligated to repurchase.  The Fund will
also  continue to be subject to the risk of a decline in the market value of the
securities  sold under the agreements  because it will require 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.  In  addition,  the Fund will not enter  into
reverse repurchase  agreements or borrow money, except from banks as a temporary
measure for extraordinary emergency purposes in amounts not to exceed 33 1/3% of
the value of the Fund's total assets  (including the amount  borrowed)  taken at
market value. The Fund will not leverage to attempt to increase income. The Fund
will not  purchase  securities  while  outstanding  borrowings  exceed 5% of the
Fund's total assets. The Fund will enter into reverse repurchase agreements only
with federally insured banks 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 15% of its net
assets  in  illiquid  investments.  If  the  Trustees  determine,  based  upon a
continuing review of the trading markets for specific Section 4(2) paper or Rule
144A securities, that they are liquid, they will not be subject to the 15% limit
on illiquid  investments.  The Trustees may adopt guidelines and delegate to the
Adviser the daily  function of  determining  the  monitoring  and  liquidity  of
restricted securities.  The Trustees,  however, will retain sufficient oversight
and  be  ultimately  responsible  for  the  determinations.  The  Trustees  will
carefully monitor the Fund's  investments in these securities,  focusing on such
important  factors,  among others,  as valuation,  liquidity and availability of
information.  This  investment  practice could have the effect of increasing the
level of illiquidity in the Fund if qualified  institutional buyers become for a
time uninterested in purchasing these restricted securities.

Options on Securities  and Securities  Indices.  The Fund may purchase and write
(sell)  call and put  options  on  securities  in which it may  invest or on any
securities  index based on securities in which it may invest.  These options may
be  listed  on  national  domestic   securities   exchanges  or  traded  in  the
over-the-counter  market.  The Fund may write  covered put and call  options and
purchase put and call options to enhance total return,  as a substitute  for the
purchase or sale of securities,  or to protect against  declines in the value of
portfolio  securities  and against  increases  in the cost of  securities  to be
acquired.

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

All call and put options written by the Fund are covered.  A written call option
or put option may be covered by (i) maintaining  cash or liquid  securities 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  of the type in which it
may  invest.  The Fund may also  sell  call  and put  options  to close  out its
purchased options.

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


                                       6
<PAGE>


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

The Fund's options  transactions  will be subject to limitations  established by
each of the exchanges, boards of trade or other trading facilities on which such
options are traded.  These  limitations  govern the maximum number of options in
each class which may be written or  purchased  by a single  investor or group of
investors  acting in concert,  regardless  of whether the options are written or
purchased on the same or different  exchanges,  boards of trade or other 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
dispose of assets held in a segregated  account until the options  expire or are
exercised. Similarly, if the Fund is unable to effect a closing sale transaction
with respect to options it has purchased,  it would have to exercise the options
in order to  realize  any  profit  and will  incur  transaction  costs  upon the
purchase or sale of underlying securities.

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


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


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

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

Hedging  and Other  Strategies.  Hedging is an attempt  to  establish  with more
certainty than would otherwise be possible the effective price or rate of return
on portfolio  securities or securities  that the Fund proposes to acquire.  When
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  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  decline
in market prices that would adversely  affect the value of the Fund's  portfolio
securities. Such futures contracts may include contracts for the future delivery
of securities  held by the Fund or securities  with  characteristics  similar to
those of the Fund's portfolio securities.

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

                                       8
<PAGE>


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

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

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

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

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

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

To the  extent  that the Fund  engages  in  nonhedging  transactions  in futures
contracts  and options on futures,  the  aggregate  initial  margin and premiums
required to establish these  nonhedging  positions will not exceed 5% of the net
asset  value of the Fund's  portfolio,  after  taking  into  account  unrealized
profits and losses on any such  positions and excluding the amount by which such
options  were  in-the-money  at the time of  purchase.  The Fund will  engage in
transactions  in futures  contracts and related  options only to the extent such
transactions  are consistent with the  requirements of the Internal Revenue Code
of 1986,  as amended  (the  "Code"),  for  maintaining  its  qualification  as a
regulated investment company for federal income tax purposes.

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

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

Perfect correlation between the Fund's futures positions and portfolio positions
will be impossible to achieve. In the event of an imperfect  correlation between
a futures  position and a portfolio  position which is intended to be protected,
the desired  protection  may not be obtained and the Fund may be exposed to risk
of loss.

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

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

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

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

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

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

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

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

INVESTMENT RESTRICTIONS

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

                                       11

The Fund may not:

(1)      Issue senior securities, except as permitted by paragraphs (2), (4) and
         (5) below. For purposes of this restriction,  the issuance of shares of
         beneficial  interest in  multiple  classes or series,  the  deferral of
         Trustees'  fees,  the purchase or sale of options,  futures  contracts,
         forward   commitments  and  repurchase   agreements   entered  into  in
         accordance with the Fund's investment policies or within the meaning of
         paragraph (5) below, are not deemed to be senior securities.

(2)      Borrow money, except for the following extraordinary or emergency
         purposes: (i) from banks for temporary or short-term purposes or for
         the clearance of transactions in amounts not to exceed 33 1/3% of the
         value of the Fund's total assets (including the amount borrowed) taken
         at market value; (ii) in connection with the redemption of Fund shares
         or to finance failed settlements of portfolio trades without
         immediately liquidating portfolio securities or other assets; (iii) in
         order to fulfill commitments or plans to purchase additional securities
         pending the anticipated sale of other portfolio securities or assets;
         (iv) in connection with entering into reverse repurchase agreements and
         dollar rolls, but only if after each such borrowing there is asset
         coverage of at least 300% as defined in the 1940 Act; and (v) as
         otherwise permitted under the1940 Act. For purposes of this investment
         restriction, the deferral of Trustees' fees and transactions in short
         sales, futures contracts, options on futures contracts, securities or
         indices and forward commitment transactions shall not constitute
         borrowing.

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

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

(5)      Invest in  commodities or in commodity  contracts  other than financial
         derivatives   contracts.   Financial  derivatives  include  options  on
         securities,  indices and  currency,  futures  contracts on  securities,
         indices and  currency  and  options on such  futures,  forward  foreign
         currency exchange contracts, forward commitments,  swaps, caps, floors,
         collars  and  swaptions  entered  into in  accordance  with the  Fund's
         investment policies.

(6)      Purchase the securities of issuers  conducting their principal activity
         in the same industry if, immediately after such purchase,  the value of
         its investments in such industry would equal or exceed 25% of its total
         assets  taken at market  value at the time of such  investment;  except
         that the Fund  intends to invest  more than 25% of its total  assets in
         real estate  companies as defined in the  prospectus.  This  limitation
         does not apply to investments in obligations of the U.S.  Government or
         any of its agencies or instrumentalities.

                                       12
<PAGE>


(7)      with respect to 75% of the Fund's total assets,  purchase securities of
         an  issuer   (other  than  the  U.S.   Government,   its   agencies  or
         instrumentalities), if:

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

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

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

The Fund may not:

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

(b)      Purchase securities on margin.

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

(d)      Invest 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 or Directors of the Adviser, or Officers
or Directors of the Fund's  principal  distributor,  John  Hancock  Funds,  Inc.

Boston, Massachusetts


INVESTMENT ADVISORY AND OTHER SERVICES

The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts 02199-7603,
was  organized in 1968 and 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  with the Adviser
(the  "Advisory  Agreement")  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 an investment  management fee, which is accrued daily, of 0.80%
of the average of the 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 has agreed to limit Fund  expenses  (excluding  12b-1  expenses)  to
1.35% of the Fund's  average  daily net assets (at least until May 1, 2000.) 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.


                                       23
<PAGE>


For the period from  September  30, 1998 to December  31,  1998,  advisory  fees
payable to the Fund's adviser amounted to $2,008 prior to the expense  reduction
by the Adviser.  After the expense  reduction  the Fund paid no advisory fee for
the period.

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 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 their  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 to the Fund or its
shareholders  for any  error  of  judgment  or  mistake  of law or for any  loss
suffered  by the Fund in  connection  with the  matters  to which  its  Advisory
Agreement relates,  except a loss resulting from willful misfeasance,  bad faith
or gross  negligence on the part of the Adviser in the performance of its duties
or from  their  reckless  disregard  of the  obligations  and  duties  under the
Advisory Agreement.

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

The Advisory Agreement was approved by all Trustees.  The Advisory Agreement and
Distribution  Agreement  (discussed  below) will continue in effect from year to
year,  provided  that its  continuance  is approved  annually both by (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 it is assigned.

Accounting and Legal Services Agreement.  The Trust, on behalf of the Fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this agreement,  the Adviser  provides the Fund with certain tax,  accounting
and legal services. For the period from September 30, 1998 to December 31, 1998,
the Fund paid the Adviser $36 or services under this agreement.


                                       24
<PAGE>


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. In the case of the Adviser, some of
these  restrictions are:  pre-clearance for all personal trades and a ban on the
purchase of initial  public  offerings,  as well as  contributions  to specified
charities  of  profits  on  securities  held  for  less  than  91  days.   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 and Class C shares,  the  broker  receives
compensation  immediately  but John Hancock Funds is  compensated  on a deferred
basis.

There were no  underwriting  commissions  for sales of the Fund's Class A shares
(the "Plans") for the period from September 30, 1998 to December 30, 1998. There
were no Class B or Class C shares  issued  during the period ended  December 31,
1998.

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 0.30% for Class A shares  and 1.00% for Class B
and Class C shares of the Fund's average daily net assets attributable to shares
of that class.  However,  the service  fees 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 and Class C shares only,  interest  expenses on  unreimbursed
distribution  expenses.  The  service  fees will be used to  compensate  Selling
Brokers and others for providing  personal and account  maintenance  services to
shareholders.  In the event 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 the Class B and Class C Plans as a liability of the
Fund because the Trustees may terminate the Class B and /or Class C Plans at any
time with no additional liability for these expenses to the shareholders and the
Fund. For the period from September 30, 1998 to December 31, 1998, there were no
Class B or Class C shares of the Fund issued.


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.


                                       25
<PAGE>


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


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


Amounts paid to the 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 the
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.

SALES COMPENSATION


As part of their business  strategies,  the Fund, along with John Hancock Funds,
pays compensation to financial services firms that sell the fund's 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 fund's  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 by the Fund.


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.

NET ASSET VALUE

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

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

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

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

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

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

INITIAL SALES CHARGE ON CLASS A SHARES

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

The sales  charges  applicable  to  purchases  of Class A shares of the Fund are
described in the Prospectus. Methods of obtaining reduced sales charges referred
to generally in the Prospectus are described in detail below. In calculating the
sales charge  applicable to current purchases of Class A shares of the Fund, the
investor  is  entitled to  cumulate  current  purchases  with the greater of the
current value (at offering  price) of the Class A shares of the Fund, 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 contingent  deferred sales charge ("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, grandparents, grandchildren, mother, father, sister,
         brother,  mother-in-law,  father-in-law,  daughter-in-law,  son-in-law,
         niece,  nephew 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.

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:


                                       29
<PAGE>


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        Shareholders  of John  Hancock  Funds PLC who become U.S.  residents or
         citizens and transfer their existing  assets from John Hancock Fund PLC
         to the Fund.


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, for each Fund, if
         the shares are redeemed  within 12 months after the end of the calendar
         year in which the  purchase  was made,  a CDSC will be  imposed  at the
         following rate:

         Amount Invested                                           CDSC RATE
         ---------------                                           ---------

         $1 to $4,999,000                                            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). A company's (not an individual's) qualified and non-qualified retirement
plan  investments can be combined to take advantage of this  privilege.  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.  A company's (not an  individual's)
qualified and non-qualified  retirement plan investments can be combined to take
advantage of this privilege.

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. A individual's  non-qualified  and qualified  retirement plan
investments  cannot be combined to satisfy 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 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 charge 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  Class A 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 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.



                                       31
<PAGE>


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 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:

    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.


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:

         subsequent  investments (less  redemptions) in that account at the time

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

SPECIAL REDEMPTIONS

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

ADDITIONAL SERVICES AND PROGRAMS

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


Exchanges  between funds with shares that are not subject to a CDSC are based on
their  respective  net asset values.  No sales charge or  transaction  charge is
imposed.  Shares of the Fund which are subject to a CDSC may be  exchanged  into
shares of any of the other John Hancock funds that are subject to a CDSC without
incurring the CDSC; however,  the shares acquired in an exchange will be subject
to the CDSC schedule of the shares acquired if and when such shares are redeemed
(except that shares  exchanged into John Hancock 500 Index Fund and John Hancock
Intermediate  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 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 the Fund shares. Since the redemption price of the Fund shares may
be more or less than the shareholder's cost,  depending upon the market value of
the securities owned by the Fund at the time of redemption,  the distribution of
cash  pursuant  to this  plan  may  result  in  realization  of gain or loss for
purposes  of  Federal,  state and  local  income  taxes.  The  maintenance  of a
Systematic  Withdrawal Plan  concurrently with purchases of additional shares of
the Fund could be disadvantageous to a shareholder  because of the initial sales
charge  payable  on such  purchases  of Class A shares  and the CDSC  imposed on
redemptions  of Class B and Class C shares and because  redemptions  are taxable
events.  Therefore,  a shareholder  should not purchase  shares at the same time
that 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.



                                       35

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 nonpayment 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 Trustees  have  authorized  shares of the Fund and three other
series:  John Hancock Small Cap Growth Fund, John Hancock Global Technology Fund
and John Hancock 500 Index Fund.  Additional  series may be added in the future.
The Declaration of Trust also authorizes the Trustees to classify and reclassify
the  shares  of the  Fund,  or any new  series  of the  Trust,  into one or more
classes.  The Trustees  have also  authorized  the issuance of three  classes of
shares of the Fund, designated as Class A, Class B and Class C.


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


Dividends paid by the Fund, if any, with respect to each class of shares will be
calculated in the same manner,  at the same time and on the same day and will be
in the same amount, except for differences resulting from the facts that (i) the
distribution  and service fees relating to each class will be borne  exclusively
by that class, (ii) Class B and Class C shares will pay higher  distribution and
service  fees than Class A shares  and (iii) each class of shares  will bear any
class  expenses  properly  allocable  to that  class of  shares,  subject to the
conditions   the  Internal   Revenue   Service   imposes  with  respect  to  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 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.

Selling activities for the Fund may not take place outside the U.S. except with
U.S. military bases, APO addresses and U.S. diplomats. Brokers of record on
Non-U.S. investors' accounts with foreign mailing addresses are required to
certify that all sales activities have occurred, and in the future will occur,
only in the U.S. A Foreign corporation may purchase shares of the Fund only if
it has a U.S. mailing address.

TAX STATUS

The Fund, is treated as a separate  entity for  acccounting and tax purposes and
has qualify 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
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
this tax by satisfying such distribution requirements.


                                       38
<PAGE>


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

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

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

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

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


                                       39
<PAGE>


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

Upon a redemption or other  disposition of Fund shares (including by exercise of
the  exchange  privilege)  in a  transaction  that is  treated as a sale for tax
purposes, a shareholder will ordinarily 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 shares of
the Fund cannot be taken into account for purposes of  determining  gain or loss
on the redemption or exchange of such shares within 90 days after their purchase
to the  extent  Class A shares  of the Fund or  another  John  Hancock  fund are
subsequently  acquired  without  payment  of a  sales  charge  pursuant  to  the
reinvestment or exchange  privilege.  This disregarded  charge will result in an
increase  in the  shareholder's  tax  basis in the  Class A 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.

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 long-term  capital gains  realized in any
year to the extent  that a capital  loss is  carried  forward  from prior  years
against such gain.  To the extent such excess was retained and not  exhausted by
the carryforward of prior years' capital losses,  it would be subject to Federal
income tax in the hands of the Fund.  Upon proper  designation of this amount by
the Fund, each  shareholder  would be treated for Federal income tax purposes as
if the Fund had  distributed  to him on the last day of its taxable year his pro
rata share of such excess,  and he had paid his pro rata share of the taxes paid
by the  Fund  and  reinvested  the  remainder  in the  Fund.  Accordingly,  each
shareholder  would (a) include  his pro rata share of such  excess as  long-term
capital gain in his tax 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.


                                       40
<PAGE>


For Federal  income tax  purposes,  the Fund is permitted to carry forward a net
capital loss in any year to offset net capital gains,  if any,  during the eight
years following the year of the loss. To the extent subsequent net capital gains
are offset by such losses, they would not result in Federal income tax liability
to  the  Fund  and,  as  noted  above,  would  not be  distributed  as  such  to
shareholders.  Presently,  there  are no  realized  capital  loss  carryforwards
available to offset future net realized capital gains.

For purposes of the  dividends-received  deduction  available  to  corporations,
dividends  received by the Fund,  if any,  from U.S.  domestic  corporations  in
respect of the stock of such  corporations  held by the Fund,  for U.S.  Federal
income  tax  purposes,  for at least  46 days  (91  days in the case of  certain
preferred  stock)  during a prescribed  period  extending  before and after each
dividend and distributed  and properly  designated by the Fund may be treated as
qualifying  dividends.  Corporate  shareholders  must  meet the  holding  period
requirements  stated  above with  respect  to their  shares of the Fund for each
dividend in order to qualify for the  deduction  and, if they have any debt that
is deemed under the Code directly  attributable to Fund shares,  may be denied a
portion of the dividends  received  deduction.  The entire qualifying  dividend,
including  the  otherwise-deductible  amount,  will be included  in  determining
alternative  minimum taxable income,  which may increase its alternative minimum
tax liability,  if any.  Additionally,  any corporate shareholder should consult
its tax adviser  regarding the possibility  that its tax basis in its shares may
be  reduced,  for  Federal  income  tax  purposes,  by reason of  "extraordinary
dividends"  received  with  respect to the shares  and, to the extent such basis
would be  reduced  below  zero,  that  current  recognition  of income  would be
required.

The Fund is required to accrue income on any debt securities that have more than
a de minimis amount of original issue discount (or debt securities acquired at a
market  discount,  if the Fund  elects  to  include  market  discount  in income
currently) prior to the receipt of the corresponding  cash payment.  The mark to
market or  constructive  sale  rules  applicable  to certain  options,  futures,
forward  contracts,  short sales or other transactions may also require the Fund
to recognize income or gain without a concurrent receipt of cash.  Additionally,
some countries  restrict  repatriation which may make it difficult or impossible
for the Fund to obtain  cash  corresponding  to its  earnings or assets in those
countries.  However,  the Fund must distribute to shareholders  for each taxable
year  substantially all of its net income and net capital gains,  including such
income or gain, to qualify as a regulated investment company and avoid liability
for any federal income or excise tax. Therefore, the Fund may have to dispose of
its portfolio securities under  disadvantageous  circumstances to generate cash,
or borrow the cash, to satisfy these distribution requirements.

If the Fund has rental  income or income from the  disposition  of real property
acquired  as a result of a default  on, or other wise in  connection  with,  the
securities  the Fund owns,  the receipt of such income may adversely  affect the
Fund's ability to retain its tax status as a regulated  investment company.  The
Fund intends to avoid losing its status by  disposing  of any  investments  that
produce these types of nonqualifying income as soon as practical.

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.


                                       41

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

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

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

Certain options,  futures and forward foreign currency  contracts  undertaken by
the Fund may cause the Fund to recognize  gains or losses from marking to market
even  though  its  positions  have not been sold or  terminated  and  affect the
character  as  long-term  or  short-term  (or,  in the case of foreign  currency
contracts,  as  ordinary  income or loss) and timing of some  capital  gains and
losses realized by the Fund. Additionally, the Fund may be required to recognize
gain,  but not  loss,  if an  option,  futures  contract,  short  sale or  other
transaction  is  treated  as a  constructive  sale of an  appreciated  financial
position  in the Fund's  portfolio.  Also,  certain of the Fund's  losses on its
transactions  involving options,  futures or forward contracts and/or offsetting
or successor  portfolio  positions may be deferred  rather than being taken into
account  currently in calculating the Fund's taxable income or gain.  Certain of
these 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 minimize any potential adverse tax consequences.

The  foregoing  discussion  relates  solely to U.S.  Federal  income  tax law as
applicable to U.S. persons (i.e.,  U.S.  citizens or residents and U.S. domestic
corporations,  partnerships,  trusts or estates)  subject to tax under such law.
The discussion does not address special tax rules applicable to certain types 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 shares of the Fund 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 Fund
investment is effectively  connected will be subject to U.S.  Federal income tax
treatment that is different from that described  above.  These  investors may be
subject to non- resident  alien  withholding  tax at the rate of 30% (or a lower
rate under an applicable  tax treaty) on amounts  treated as ordinary  dividends
from the Fund and, unless an effective IRS Form W-8 or authorized substitute for
Form W-8 is on file, to 31% backup  withholding  on certain other  payments from
the Fund.  Non-U.S.  investors should consult their tax advisers  regarding such
treatment and the application of foreign taxes to an investment in the Fund.

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

CALCULATION OF PERFORMANCE

As of December 31, 1998,  the  cumulative  total return on Class A shares of the
Fund since inception on September 30, 1998 was -4.58%.

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


     n ______
T = \ / ERV/P - 1


Where:

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

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


                                       43
<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 or Class C shares  into  account.  Excluding  the  Fund's
sales charge on Class A shares and the CDSC on Class B and Class C shares from a
total return calculation produces a higher total return figure.

The Fund may advertise yield, where appropriate. 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,  if
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).

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

Performance  rankings and ratings  reported  periodically in national  financial
publications  such as MONEY  MAGAZINE,  FORBES,  BUSINESS  WEEK, THE WALL STREET
JOURNAL,  MICROPAL,  INC.,  MORNINGSTAR,  STANGER'S  and  BARRON'S  may  also be
utilized.  The Fund's promotional and sales literature may make reference to the
Fund's  "beta".  Beta is a 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,  which consists of officers and
directors  of the  Adviser  and  officers  and  Trustees  of the  Trust  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  officers  of the Fund,  will
offer the best  price and  market for the  execution  of each such  transaction.
Purchases from underwriters of portfolio  securities may include a commission or
commissions paid by the issuer and  transactions  with dealers serving as market
maker reflect a "spread." Debt  securities  are generally  traded on a net basis
through  dealers  acting for their own account as principals and not as brokers;
no brokerage commissions are payable on such transactions.

In the U.S. Government  securities market,  securities are generally traded on a
"net" basis with  dealers  acting as principal  for their own account  without a
stated commission,  although the price of the security usually includes a profit
to the  dealer.  On  occasion,  certain  money  market  instruments  and  agency
securities  may be  purchased  directly  from  the  issuer,  in  which  case  no
commissions  or  premiums  are paid.  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.
The policy  governs the selection of brokers and dealers and the market in which
a transaction is executed.  Consistent with the foregoing  primary  policy,  the
Rules of Fair Practice of the National  Association of Securities Dealers,  Inc.
and such other policies as the Trustees may determine,  the Adviser may consider
sales of shares of the Fund as a factor in the  selection of  broker-dealers  to
execute the Fund's portfolio transactions.

To the extent  consistent  with the foregoing,  the Fund will be governed in the
selection of 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. It
is not  possible  to place a dollar  value on  information  and  services  to be
received  from  brokers  and  dealers,  since  it is only  supplementary  to the
research  efforts of the  Adviser.  The receipt of research  information  is not
expected to reduce  significantly  the  expenses of the  Adviser.  The  research
information  and  statistical  assistance  furnished  by brokers and dealers may
benefit  the Life  Company  or  other  advisory  clients  of the  Adviser,  and,
conversely,  brokerage commissions and spreads paid by other advisory clients of
the  Adviser  may result in  research  information  and  statistical  assistance
beneficial to the Fund.  The Fund will make no commitment to allocate  portfolio
transactions  upon any prescribed  basis.  While the Adviser's  officers will be
primarily  responsible for the allocation of the Fund's brokerage business,  the
policies and practices of the Adviser in this regard must be consistent with the
foregoing  and will at all times be subject to review by the  Trustees.  For the
period from  September 30, 1998 to December 31, 1998,  the Fund paid  negotiated
brokerage commission in the amount of $5,073.


                                       45
<PAGE>


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 period from September 30, 1998
to December 31, 1998,  the Fund paid $175.00 to compensate  brokers for research
services such as industry and company reviews and evaluations of the securities.

The  Adviser's  indirect  parent,  the  Life  Company,   is  the  indirect  sole
shareholder of Signator Investors,  Inc. a broker dealer (until January 1, 1999,
John Hancock Distributors,  Inc.) ("Signator" 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  transaction  with or
through Affiliated  Brokers.  For the period from September 30, 1998 to December
31, 1998, the Fund paid no brokerage commissions to any Affiliated Broker.

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

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

TRANSFER AGENT SERVICES


John Hancock Signature  Services,  Inc., 1 John Hancock Way, Suite 1000, Boston,
Massachusetts  02217-1000,  a  wholly-owned  indirect  subsidiary  of  the  Life

these  expenses  are  aggregated  and charged to the Fund and  allocated to each
class on the basis of their relative net asset value.

APPENDIX-A -Description of Investment Risks

MORE ABOUT RISK

A fund's risk profile is largely  defined by the fund's  primary  securities and
investment  practices.  You may find the most concise  description of 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. On the following page are brief definitions
of certain  associated risks with them, with examples of related  securities and
investment  practices  included in brackets.  See the "Investment  Objective and
Policies" and "Investment  Restrictions  section 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 performance of the fund
will be positive over any period of time.

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)(e.g. short sales, financial futures
and options; securities and index options, currency contracts).

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.   borrowing;   reverse   repurchase   agreements,   repurchase
agreements, securities lending, non-investment-grade debt securities, options on
securities and indices).

Currency risk The risk that  fluctuations in the exchange rates between the U.S.
dollar and foreign  currencies may negatively affect an investment (e.g. foreign
securities, futures and related options, currency contracts).

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

Information  risk The risk that key  information  about a security  or market is
inaccurate or unavailable (e.g. non-investment-grade debt securities and foreign
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  and  financial   futures  and  options;
securities and index options).

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,  short sales,  when-issued securities
and forward  commitments,  financial  futures and options;  securities and index
options; currency contracts).


                                      A-1
<PAGE>


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 (e.g.  short sales,
when-issues   securities  and  forward  commitments,   restricted  and  illiquid
securities,  financial  futures  and  options;  securities  and  index  options,
currency contracts).

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.  Common to all  stocks and bonds and the
mutual  funds  that  invest  in them  (e.g.  short  sales,  short-term  trading,
when-issued  securities  and  forward  commitments,   non-investment-grade  debt
securities,  foreign securities,  restricted and illiquid securities,  financial
futures and options; securities and index option).

Natural event risk The risk of losses  attributable to natural  disasters,  crop
failures and similar events (e.g. foreign securities).

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. short sales,  when-issued  securities and forward commitments,
financial   futures  and  options;   securities  and  index  options,   currency
contracts).

Political  risk  The risk of  losses  directly  attributable  to  government  or
political actions of any sort (e.g. foreign securities).

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

Valuation  risk The risk that a fund has valued  certain of its  securities at a
higher price than it can sell them for (e.g. restricted, illiquid securities and
non-investment-grade debt securities).

APPENDIX B - Description of Bond Ratings

RATINGS

Bonds.

Standard & Poor's Bond Ratings

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.

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.

To provide more detailed  indications of credit  quality,  the ratings AA to BBB
may be  modified  by the  addition  of a plus or  minus  sign  to show  relative
standing within the major rating categories.

A provisional rating,  indicated by "p" following a rating, is sometimes used by
Standard & Poor's.  It assumes the  successful  completion  of the project being
financed by the issuance of the bonds being rated and indicates  that payment of
debt service  requirements is largely or entirely  dependent upon the successful
and timely  completion of the project.  This rating,  however,  while addressing
credit quality subsequent to completion,  makes no comment on the likelihood of,
or the risk of default upon failure of, such completion.

Moody's Bond Ratings

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.  Generally speaking, the safety of
obligations of this class is so absolute that with the  occasional  exception of
oversupply in a few specific instances,  characteristically,  their market value
is affected solely by money market fluctuations.

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  fluctuation of protective  elements
may be of greater  amplitude or there may be other  elements  present which make
the long-term risks appear  somewhat  larger than in Aaa securities.  The market
value of Aa bonds is virtually immune to all but money market  influences,  with
the occasional exception of oversupply in a few specific instances.


                                      B-1
<PAGE>


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.

BB Debt rated BB 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.

Rating symbols may include numerical modifiers 1, 2 or 3. The numerical modifier
1 indicates that the security  ranks at the high end, 2 in the mid-range,  and 3
nearer the low end, of the generic  category.  These modifiers of rating symbols
Aa, A and Baa are to give  investors a more precise  indication of relative debt
quality in each of the historically defined categories.

Conditional  ratings,  indicated by "Con", are sometimes given when the security
for the bond depends upon the completion of some act or the  fulfillment of some
condition.  Such  bonds,  are given a  conditional  rating  that  denotes  their
probably  credit  statute upon  completion  of that act or  fulfillment  of that
condition.

Rating symbols may include numerical modifiers 1, 2 or 3. The numerical modifier
1 indicates that the security  ranks at the high end, 2 in the mid-range,  and 3
nearer  the low  end,  of the  generic  category.  These  modifiers  are to give
investors a more  precise  indication  of relative  debt  quality in each of the
historically defined categories.

                                     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:

<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.

Ladies and Gentlemen:

         John  Hancock  Series  Trust (the  "Trust"),  of which John Hancock 500
Index Fund (the  "Fund") is a series,  has been  organized  as a business  trust
under the laws of The Commonwealth of Massachusetts to engage in the business of

interest in a separate portfolio of assets. This Agreement relates solely to the
Fund.

         The Board of Trustees of the Trust (the  "Trustees")  has selected John
Hancock Advisers,  Inc. (the "Adviser") to provide overall investment advice and
management for the Fund, and to provide  certain other  services,  as more fully
set forth below,  and the Adviser is willing to provide such advice,  management
and services under the terms and conditions hereinafter set forth.

         Accordingly, the Adviser and the Trust, on behalf of the Fund, agree as
follows:

         1.  DELIVERY OF  DOCUMENTS.  The Trust has  furnished  the Adviser with
copies, properly certified or otherwise authenticated, of each of the following:

             to time (the "Declaration of Trust");

         (b) By-Laws of the Trust as in effect on the date hereof;

         (c) Resolutions of the Trustees  selecting the Adviser as investment
             adviser for the Fund and approving the form of this Agreement;

         (d) The Trust's Code of Ethics.

         The  Trust  will  furnish  to the  Adviser  from  time to time  copies,
properly  certified  or  otherwise  authenticated,   of  all  amendments  of  or
supplements to the foregoing, if any.

<PAGE>


         2.  INVESTMENT AND MANAGEMENT  SERVICES.  The Adviser will use its best
efforts to provide to the Fund continuing and suitable  investment programs with
respect to investments,  consistent with the investment objectives, policies and
restrictions of the Fund. In the performance of the Adviser's duties  hereunder,
subject always (x) to the provisions contained in the documents delivered to the
Adviser  pursuant  to  Section  1, as each of the same may from  time to time be
amended  or  supplemented,  and (y) to the  limitations  set forth in the Fund's
then-current  Prospectus and Statement of Additional Information included in the
registration  statement  of the Trust as in effect  from time to time  under the
Securities Act of 1933, as amended,  and the Investment  Company Act of 1940, as
amended (the "1940 Act"), the Adviser will, at its own expense:

         (a)    furnish  the Fund with  advice and  recommendations,  consistent
                with the investment objectives, policies and restrictions of the
                Fund,  with respect to the purchase,  holding and disposition of
                portfolio   securities,   alone  or  in  consultation  with  any
                subadviser or subadvisers  appointed  pursuant to this Agreement
                and subject to the provisions of any  sub-investment  management
                contract  respecting the  responsibilities of such subadviser or
                subadvisers;

         (b)    advise the Fund in connection  with policy  decisions to be made
                by the  Trustees or any  committee  thereof  with respect to the

                offering and sale of shares;

<PAGE>


         (c)    the compensation and expenses of Trustees who are not interested
                persons  (as used in this  Agreement,  such term  shall have the
                meaning  specified  in  the  1940  Act)  of the  Adviser  and of
                independent  advisers,  independent  contractors,   consultants,
                managers  and other  unaffiliated  agents  employed  by the Fund
                other than through the Adviser;

         (d)    legal, accounting,  financial management,  tax and auditing fees

         (e)    the fees and disbursements of custodians and depositories of the

         (f)    taxes and governmental fees assessed against the Fund's assets

         (g)    the cost of  preparing  and  mailing  dividends,  distributions,

         (h)    brokers' commissions and underwriting fees;

         (i)    the expense of periodic  calculations of the net asset value of
                the shares of the Fund; and

         (j)    insurance premiums on fidelity, errors and omissions and other
                coverages.

         5.  COMPENSATION  OF THE  ADVISER.  For all  services  to be  rendered,
facilities  furnished  and  expenses  paid or assumed  by the  Adviser as herein
provided, the Adviser shall be entitled to a fee, paid monthly in arrears, at an
annual rate equal to 0.35% of the average daily net asset value of the Fund.

         The "average  daily net assets" of the Fund shall be  determined on the
basis set forth in the Fund's  Prospectus or otherwise  consistent with the 1940
Act and the regulations promulgated  thereunder.  The Adviser will receive a pro
rata portion of such monthly fee for any periods in which the Adviser  serves as
investment  adviser to the Fund for less than a full month.  On any day that the
net asset value calculation is suspended as specified in the Fund's  Prospectus,
the net asset  value for  purposes  of  calculating  the  advisory  fee shall be
calculated as of the date last determined.

         In the event that normal operating  expenses of the Fund,  exclusive of
certain  expenses  prescribed  by state  law,  are in excess  of any  limitation
imposed  by the law of a state  where  the Fund has  registered  its  shares  of
beneficial  interest,  the fee  payable  to the  Adviser  will be reduced to the
extent  required by law, and the Adviser will make any  additional  arrangements
that the Adviser is required by law to make.

<PAGE>


         In  addition,  the  Adviser may agree not to impose all or a portion of
its fee (in advance of the time its fee would otherwise accrue) and/or undertake
to make any  other  payments  or  arrangements  necessary  to limit  the  Fund's
expenses to any level the Adviser may specify.  Any fee reduction or undertaking
shall constitute a binding  modification of this Agreement while it is in effect
but may be discontinued or modified prospectively by the Adviser at any time.

         6. OTHER  ACTIVITIES OF THE ADVISER AND ITS AFFILIATES.  Nothing herein
contained shall prevent the Adviser or any affiliate or associate of the Adviser
from  engaging in any other  business or from  acting as  investment  adviser or
investment  manager  for any  other  person or  entity,  whether  or not  having
investment  policies or portfolios similar to the Fund's; and it is specifically
understood  that  officers,  directors and employees of the Adviser and those of
its parent  company,  John  Hancock  Mutual  Life  Insurance  Company,  or other
affiliates may continue to engage in providing portfolio management services and
advice  to other  investment  companies,  whether  or not  registered,  to other
investment  advisory  clients of the  Adviser or of its  affiliates  and to said
affiliates themselves.

         The Adviser  shall have no  obligation  to acquire  with respect to the
Fund a position in any investment which the Adviser, its officers, affiliates or
employees  may  acquire  for its or their own  accounts  or for the  account  of
another client, if, in the sole discretion of the Adviser, it is not feasible or
desirable  to  acquire  a  position  in such  investment  on behalf of the Fund.
Nothing  herein   contained   shall  prevent  the  Adviser  from  purchasing  or
recommending  the  purchase of a  particular  security  for one or more funds or
clients while other funds or clients may be selling the same security.

         7. AVOIDANCE OF INCONSISTENT  POSITION. In connection with purchases or
sales of portfolio  securities for the account of the Fund,  neither the Adviser
nor any of its investment management  subsidiaries,  nor any of the Adviser's or
such investment management subsidiaries'  directors,  officers or employees will
act as principal or agent or receive any commission,  except as may be permitted
by the  1940  Act and  rules  and  regulations  promulgated  thereunder.  If any
occasions shall arise in which the Adviser advises persons concerning the shares
of the Fund, the Adviser will act solely on its own behalf and not in any way on
behalf of the Fund. Nothing herein contained shall limit or restrict the Adviser
or any of its officers,  affiliates or employees from buying, selling or trading
in any securities for its or their own account or accounts.

         8. NO PARTNERSHIP OR JOINT VENTURE. Neither the Trust, the Fund nor the
Adviser are partners of or joint  venturers  with each other and nothing  herein
shall be construed so as to make them such partners or joint venturers or impose
any liability as such on any of them.

         9. NAME OF THE  TRUST AND THE FUND.  The Trust and the Fund may use the
name "John  Hancock" or any name or names  derived  from or similar to the names
"John Hancock  Advisers,  Inc." or "John Hancock Mutual Life Insurance  Company"
only for so long as this  Agreement  remains  in  effect.  At such  time as this
Agreement  shall no  longer  be in  effect,  the Trust and the Fund will (to the
extent  that  they  lawfully  can)  cease to use such a name or any  other  name
indicating that the Fund is advised by or otherwise  connected with the Adviser.
The Fund  acknowledges  that it has adopted the name John Hancock 500 Index Fund
through   permission  of  John  Hancock   Mutual  Life  Insurance   Company,   a
Massachusetts  insurance  company,  and agrees  that John  Hancock  Mutual  Life
Insurance Company reserves to itself and any successor to its business the right
to grant the  nonexclusive  right to use the name "John  Hancock" or any similar
name or names to any other  corporation or entity,  including but not limited to
any investment  company of which John Hancock  Mutual Life Insurance  Company or
any subsidiary or affiliate thereof shall be the investment adviser.

<PAGE>


         10.  LIMITATION  OF LIABILITY OF THE ADVISER.  The Adviser shall not be
liable for any error of judgment  or mistake of law or for any loss  suffered by
the Trust in connection with the matters to which this 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
by it of its  obligations  and duties  under this  Agreement.  Any person,  even
though  also  employed by the  Adviser,  who may be or become an employee of and
paid by the  Trust  shall  be  deemed,  when  acting  within  the  scope  of his
employment by the Fund, to be acting in such employment solely for the Trust and
not as the Adviser's employee or agent.

         11. DURATION AND  TERMINATION OF THIS  AGREEMENT.  This Agreement shall
remain in force until June 30, 2000, and from year to year thereafter,  but only
so long as such continuance is specifically  approved at least annually by (a) a
majority of the Trustees who are not interested persons of the Adviser or (other
than as Board  members) of the Fund,  cast in person at a meeting called for the
purpose of voting on such  approval,  and (b) either (i) the  Trustees or (ii) a
majority of the outstanding  voting  securities of the Fund. This Agreement may,
on 60 days' written notice, be terminated at any time without the payment of any
penalty by the vote of a majority of the  outstanding  voting  securities of the
Fund, by the Trustees or by the Adviser. Termination of this Agreement shall not
be deemed to terminate or otherwise  invalidate  any  provisions of any contract
between the  Adviser and any other  series of the Trust.  This  Agreement  shall
automatically  terminate in the event of its  assignment.  In  interpreting  the
provisions of this Section 11, the definitions  contained in Section 2(a) of the
1940 Act (particularly the definitions of "assignment,"  "interested person" and
"voting security") shall be applied.

         12. AMENDMENT OF THIS AGREEMENT.  No provision of this Agreement may be
changed,  waived,  discharged or terminated orally, but only by an instrument in
writing  signed by the party against which  enforcement  of the change,  waiver,
discharge or  termination  is sought,  and no amendment,  transfer,  assignment,
sale,  hypothecation  or  pledge  of this  Agreement  shall be  effective  until
approved by (a) the  Trustees,  including a majority of the Trustees who are not
interested  persons of the Adviser or (other than as Trustees) of the Fund, cast
in person at a meeting  called for the purpose of voting on such  approval,  and
(b) a majority of the outstanding  voting  securities of the Fund, as defined in
the 1940 Act.

         13.  GOVERNING LAW. This  Agreement  shall be governed and construed in
accordance with the laws of The Commonwealth of Massachusetts.

<PAGE>



         14.  SEVERABILITY.  The provisions of this Agreement are independent of
and separable  from each other,  and no provision  shall be affected or rendered
invalid or  unenforceable by virtue of the fact that for any reason any other or
others of them may be deemed invalid or unenforceable in whole or in part.

         15.  MISCELLANEOUS.  The  captions in this  Agreement  are included for
convenience  of  reference  only  and  in no  way  define  or  limit  any of the
provisions  hereof or  otherwise  affect  their  construction  or  effect.  This
Agreement may be executed  simultaneously in two or more  counterparts,  each of
which shall be deemed an original,  but all of which together  shall  constitute
one and the same  instrument.  The name John  Hancock 500 Index Fund is a series
designation  of the  Trustees  under  the  Trust's  Declaration  of  Trust.  The
Declaration  of  Trust  has  been  filed  with  the  Secretary  of  State of The
Commonwealth  of  Massachusetts.  The obligations of the Fund are not personally
binding  upon,  nor shall  resort be had to the private  property of, any of the
Trustees,  shareholders,  officers,  employees or agents of the Trust,  but only
upon the Fund and its property. The Fund shall not be liable for the obligations
of any other  series of the Trust and no other  series  shall be liable  for the
Fund's obligations hereunder.

                                Yours very truly,

                                JOHN HANCOCK SERIES TRUST

                           MASTER CUSTODIAN AGREEMENT


        This  Agreement  is made as of the 30th day of  September,  1998 between
each investment company advised by John Hancock Advisers, Inc. which has adopted
this  Agreement  in the manner  provided  herein and Brown  Brothers  Harriman &
Company  (hereinafter  called  "Bank",   "Custodian"  and  "Agent"),  a  limited
partnership  formed  under the laws of the  State of New York  with a  principal
place of business at 40 Water Street, Boston, MA 02109.

        Whereas, each such investment company is registered under the Investment
Company  Act of 1940  and has  appointed  the  Bank to act as  Custodian  of its
property and to perform certain duties as its Agent,  as more fully  hereinafter
set forth; and

        Whereas,  the Bank is  willing  and able to act as each such  investment
company's Custodian and Agent,  subject to and in accordance with the provisions
hereof;

        Now,  therefore,  in  consideration  of the  premises  and of the mutual
covenants and agreements herein contained,  each such investment company and the
Bank agree as follows:

1.  Definitions

        Whenever used in this Agreement, the following words and phrases, unless
the context otherwise requires, shall have the following meanings:

        (a) "Fund"  shall mean the  investment  company  which has adopted  this
Agreement  and is listed on  Appendix A hereto.  If the Fund is a  Massachusetts
business  trust or  Maryland  corporation,  it may in the future  establish  and
designate  other  separate and distinct  series of shares,  each of which may be
called a  "portfolio";  in such case,  the term "Fund"  shall also refer to each
such separate series or portfolio.

        (b) "Board" shall mean the board of directors/trustees/managing  general
partners/director general partners of the Fund, as the case may be.

        (c) "The Depository  Trust Company",  a clearing agency  registered with
the  Securities  and Exchange  Commission  under  Section 17A of the  Securities
Exchange  Act of 1934 which acts as a securities  depository  and which has been
specifically approved as a securities depository for the Fund by the Board.

        (d) "Authorized  Officer",  shall mean any of the following  officers of
the  Trust:  The  Chairman  of the  Board of  Trustees,  the  President,  a Vice
President,  the  Secretary,  the  Treasurer or Assistant  Secretary or Assistant
Treasurer,  or any  other  officer  of the  Trust  duly  authorized  to  sign by
appropriate resolution of the Board of Trustees of the Trust.
<PAGE>


        (e) "Participants Trust Company",  a clearing agency registered with the
Securities and Exchange  Commission under Section 17A of the Securities Exchange
Act  of  1934  which  acts  as  a  securities  depository  and  which  has  been
specifically approved as a securities depository for the Fund by the Board.

        (f) "Approved  Clearing  Agency" shall mean any other domestic  clearing
agency registered with the Securities and Exchange  Commission under Section 17A
of the Securities Exchange Act of 1934 which acts as a securities depository but
only if the  Custodian  has  received  a  certified  copy of a vote of the Board
approving such clearing agency as a securities depository for the Fund.

        (g)  "Federal  Book-Entry  System"  shall  mean  the  book-entry  system
referred to in Rule 17f-4(b) under the Investment Company Act of 1940 for United
States and federal agency securities (i.e., as provided in Subpart O of Treasury
Circular No. 300, 31 CFR 306,  Subpart B of 31 CFR Part 350, and the  book-entry
regulations of federal agencies substantially in the form of Subpart O).

        (h)  "Approved  Foreign  Securities  Depository"  shall  mean a  foreign
securities  depository  or clearing  agency  referred to in rule 17f-4 under the
Investment  Company Act of 1940 for foreign securities but only if the Custodian
has received a certified copy of a vote of the Board  approving such  depository
or clearing agency as a foreign securities depository for the Fund.

        (i)  "Approved  Book-Entry  System for  Commercial  Paper"  shall mean a
system  maintained by the Custodian or by a  subcustodian  employed  pursuant to
Section 2 hereof for the holding of commercial paper in book-entry form but only
if the Custodian has received a certified copy of a vote of the Board  approving
the participation by the Fund in such system.

        (j) The Custodian shall be deemed to have received "proper instructions"
in respect of any of the matters  referred to in this  Agreement upon receipt of
written or facsimile  instructions  signed by such one or more person or persons
as the Board  shall  have from time to time  authorized  to give the  particular
class of instructions in question.  Electronic instructions for the purchase and
sale of securities which are transmitted by John Hancock  Advisers,  Inc. to the
Custodian  through the John Hancock  equity  trading system and the John Hancock
fixed income trading system shall be deemed to be proper instructions;  the Fund
shall cause all such instructions to be confirmed in writing.  Different persons
may be authorized to give instructions for different purposes.  A certified copy
of a vote  of the  Board  may be  received  and  accepted  by the  Custodian  as
conclusive  evidence  of the  authority  of any  such  person  to act and may be
considered  as in full force and effect until  receipt of written  notice to the
contrary.  Such  instructions  may be general or  specific  in terms and,  where
appropriate, may be standing instructions.  Unless the vote delegating authority
to any person or persons to give a particular class of instructions specifically
requires that the approval of any person,  persons or committee shall first have
been obtained before the Custodian may act on  instructions  of that class,  the
Custodian  shall be under no  obligation  to question the right of the person or
persons  giving  such  instructions  in so  doing.  Oral  instructions  will  be
considered proper instructions if the Custodian reasonably believes them to have
been given by a person  authorized to give such instructions with respect to the
transaction involved. The Fund shall cause all oral instructions to be confirmed
in  writing.  The Fund  authorizes  the  Custodian  to tape  record  any and all
telephonic or other oral instructions given to the Custodian.  Upon receipt of a
certificate  signed by two officers

<PAGE>


of the Fund as to the authorization by the President and the Treasurer of the
Fund accompanied by a detailed description of the communication procedures
approved by the President and the Treasurer of the Fund, "proper instructions"
may also include communications effected directly between electromechanical or
electronic devices provided that the President and Treasurer of the Fund and the
Custodian are satisfied that such procedures afford adequate safeguards for the
Fund's assets. In performing its duties generally, and more particularly in
connection with the purchase, sale and exchange of securities made by or for the
Fund, the Custodian may take cognizance of the provisions of the governing
documents and registration statement of the Fund as the same may from time to
time be in effect (and votes, resolutions or proceedings of the shareholders or
the Board), but, nevertheless, except as otherwise expressly provided herein,
the Custodian may assume unless and until notified in writing to the contrary
that so-called proper instructions received by it are not in conflict with or in
any way contrary to any provisions of such governing documents and registration
statement, or votes, resolutions or proceedings of the shareholders or the
Board.

2. Employment of Custodian and Property to be Held by It

        The Fund hereby appoints and employs the Bank as its Custodian and Agent
in accordance  with and subject to the  provisions  hereof,  and the Bank hereby
accepts  such  appointment  and  employment.  The Fund  agrees to deliver to the
Custodian all securities,  participation interests,  cash and other assets owned
by  it,  and  all  payments  of  income,   payments  of  principal  and  capital
distributions and adjustments  received by it with respect to all securities and
participation  interests  owned by the  Fund  from  time to  time,  and the cash
consideration  received by it for such new or treasury shares  ("Shares") of the
Fund as may be  issued or sold from  time to time.  The  Custodian  shall not be
responsible  for any property of the Fund held by the Fund and not  delivered by
the Fund to the  Custodian.  The Fund will also deliver to the Bank from time to
time  copies of its  currently  effective  charter (or  declaration  of trust or
partnership agreement,  as the case may be), by-laws,  prospectus,  statement of
additional   information   and   distribution   agreement   with  its  principal
underwriter,  together with such resolutions, votes and other proceedings of the
Fund as may be necessary for or convenient to the Bank in the performance of its
duties hereunder.

        The Custodian may from time to time employ one or more  subcustodians to
perform  such acts and  services  upon such  terms  and  conditions  as shall be
approved from time to time by the Board.  Any such  subcustodian  so employed by
the  Custodian  shall  be  deemed  to be the  agent  of the  Custodian,  and the
Custodian shall remain primarily  responsible for the securities,  participation
interests, moneys and other property of the Fund held by such subcustodian.  Any
foreign  subcustodian  shall be a bank or  trust  company  which is an  eligible
foreign custodian within the meaning of Rule 17f-5 under the Investment  Company
Act of 1940, and the foreign custody arrangements shall be approved by the Board
and shall be in accordance  with and subject to the provisions of said Rule. For
the  purposes  of this  Agreement,  any  property  of the Fund  held by any such
subcustodian  (domestic or foreign)  shall be deemed to be held by the Custodian
under the terms of this Agreement.

3. Duties of the Custodian with Respect to Property of the Fund

     A.       Safekeeping and Holding of Property The Custodian shall
              keep safely all property of the Fund and on behalf of the Fund

              safekeeping. The Custodian shall hold, earmark and segregate
              on its books and records for the account of the Fund all
              property of the Fund, including all securities, participation
              interests and other assets of the Fund (1) physically held by
              the Custodian, (2) held by any subcustodian referred to in
              Section 2 hereof or by any agent referred to in Paragraph K
              hereof, (3) held by or maintained in The Depository Trust
              Company or in Participants Trust Company or in an Approved
              Clearing Agency or in the Federal Book-Entry System or in an
              Approved Foreign Securities Depository, each of which from
              time to time is referred to herein as a "Securities System",
              and (4) held by the Custodian or by any subcustodian referred
              to in Section 2 hereof and maintained in any Approved
              Book-Entry System for Commercial Paper.

     B.       Delivery of  Securities  The  Custodian  shall release and deliver
              securities or  participation  interests owned by the Fund held (or
              deemed to be held) by the  Custodian or maintained in a Securities
              System account or in an Approved  Book-Entry System for Commercial
              Paper account only upon receipt of proper instructions,  which may
              be continuing instructions when deemed appropriate by the parties,
              and only in the following cases:

              1)      Upon sale of such  securities or  participation  interests
                      for the account of the Fund,  but only against  receipt of
                      payment  therefor;  if  delivery  is made in Boston or New
                      York City,  payment  therefor  shall be made in accordance
                      with generally  accepted  clearing house  procedures or by
                      use of Federal Reserve Wire System procedures; if delivery
                      is made elsewhere  payment therefor shall be in accordance
                      with the  then  current  "street  delivery"  custom  or in
                      accordance with such procedures  agreed to in writing from
                      time  to  time  by the  parties  hereto;  if the  sale  is
                      effected through a Securities System, delivery and payment

<PAGE>


                      therefor  shall be made in accordance  with the provisions
                      of Paragraph L hereof;  if the sale of commercial paper is
                      to be effected through an Approved  Book-Entry  System for
                      Commercial  Paper,  delivery and payment therefor shall be
                      made in  accordance  with the  provisions  of  Paragraph M
                      hereof;  if the  securities  are to be  sold  outside  the
                      United  States,  delivery may be made in  accordance  with
                      procedures  agreed to in writing  from time to time by the
                      parties hereto; for the purposes of this subparagraph, the
                      term "sale" shall include the  disposition  of a portfolio
                      security (i) upon the exercise of an option written by the
                      Fund  and  (ii)  upon  the  failure  by the Fund to make a
                      successful bid with respect to a portfolio  security,  the
                      continued  holding of which is contingent  upon the making
                      of such a bid;

              2)      Upon  the  receipt  of  payment  in  connection  with  any
                      repurchase   agreement  or  reverse  repurchase  agreement

                      participation interests are called,  redeemed,  retired or
                      otherwise become payable; provided that, in any such case,
                      the cash or other  consideration is to be delivered to the
                      Custodian or any subcustodian employed pursuant to Section

              5)      To the issuer thereof, or its agent, for transfer into the
                      name of the Fund or into the  name of any  nominee  of the
                      Custodian  or into the name or  nominee  name of any agent
                      appointed  pursuant to Paragraph K hereof or into the name
                      or nominee name of any subcustodian  employed  pursuant to
                      Section 2 hereof;  or for exchange for a different  number
                      of bonds,  certificates or other evidence representing the

              6)      To  the  broker  selling  the  same  for   examination  in
                      accordance  with the "street  delivery"  custom;  provided
                      that the Custodian shall adopt such procedures as the Fund

                      return  to the  Custodian  by the  broker in the event the
                      broker elects not to accept them;

              7)      For exchange or conversion pursuant to any plan of merger,

                      securities,  or pursuant to provisions  for  conversion of
                      such  securities,  or pursuant  to any deposit  agreement;
                      provided  that, in any such case,  the new  securities and
                      cash,  if any, are to be delivered to the Custodian or any
                      subcustodian employed pursuant to Section 2 hereof;

<PAGE>


              8)      In the case of warrants, rights or similar securities, the
                      surrender  thereof in connection with the exercise of such
                      warrants,  rights or similar securities,  or the surrender
                      of interim receipts or temporary securities for definitive
                      securities;  provided  that,  in any  such  case,  the new
                      securities  and cash,  if any,  are to be delivered to the
                      Custodian or any subcustodian employed pursuant to Section

              9)      For delivery in  connection  with any loans of  securities
                      made by the Fund (such  loans to be made  pursuant  to the
                      terms of the Fund's current registration  statement),  but
                      only against receipt of adequate collateral as agreed upon
                      from time to time by the Custodian and the Fund, which may
                      be in the form of cash or obligations issued by the United
                      States government, its agencies or instrumentalities.

              10)     For delivery as security in connection with any borrowings
                      by the Fund requiring a pledge or  hypothecation of assets
                      by  the  Fund  (if  then  permitted  under   circumstances
                      described  in the current  registration  statement  of the
                      Fund),  provided,  that the  securities  shall be released
                      only upon payment to the Custodian of the monies borrowed,
                      except  that  in  cases  where  additional  collateral  is
                      required  to  secure a  borrowing  already  made,  further

              13)     For  delivery in  accordance  with the  provisions  of any
                      agreement among the Fund, the Custodian (or a subcustodian
                      employed  pursuant  to  Section 2  hereof),  and a futures

                      Fund;

     C.       Registration of Securities Securities held by the Custodian

              shall be registered in the name of the Fund or in the name of
              any nominee of the Fund or of any nominee of the Custodian, or

              account of the Custodian or of such agent or of such
              subcustodian containing only assets of the Fund or only assets
              held by the Custodian or such agent or such subcustodian as a
              custodian or subcustodian or in a fiduciary capacity for
              customers. All certificates for securities accepted by the
              Custodian or any such agent or subcustodian on behalf of the
              Fund shall be in "street" or other good delivery form or shall
              be returned to the selling broker or dealer who shall be
              advised of the reason thereof.

     D.       Bank Accounts The Custodian shall open and maintain a
              separate bank account or accounts in the name of the Fund,
              subject only to draft or order by the Custodian acting in
              pursuant to the terms of this Agreement, and shall hold in
              such account or accounts, subject to the provisions hereof,
              all cash received by it from or for the account of the Fund

              for the Fund may be deposited by it to its credit as Custodian
              in the Banking Department of the Custodian or in such other
              banks or trust companies as the Custodian may in its
              discretion deem necessary or desirable; provided, however,
              that every such -------- bank or trust company shall be
              qualified to act as a custodian under the Investment Company
              Act of 1940 and that each such bank or trust company and the
              funds to be deposited with each such bank or trust company
              shall be approved in writing by an Authorized Officer of the
              Fund. Such funds shall be deposited by the Custodian in its
              capacity as Custodian and shall be subject to withdrawal only
              by the Custodian in that capacity.

     E.       Payment  for  Shares  of  the  Fund  The   Custodian   shall  make
              appropriate arrangements with the Transfer Agent and the principal
              underwriter of the Fund to enable the Custodian to make certain it
              promptly receives the cash or other  consideration due to the Fund
              for such new or treasury Shares as may be issued or sold from time
              to time by the Fund,  in accordance  with the governing  documents
              and offering prospectus and statement of additional information of
              the Fund. The Custodian will provide  prompt  notification  to the
              Fund of any receipt by it of payments for Shares of the Fund.

     F.       Investment  and  Availability  of  Federal  Funds  Upon  agreement
              between the Fund and the Custodian,  the Custodian shall, upon the
              receipt   of  proper   instructions,   which  may  be   continuing
              instructions  when deemed  appropriate  by the parties,  invest in
              such  securities  and  instruments  as may be set  forth  in  such
              instructions  on  the  same  day as  received  all  federal  funds
              received  after a time agreed upon between the  Custodian  and the
              Fund.

     G.       Collections  The Custodian  shall promptly  collect all income and
              other  payments  with  respect  to  registered   securities   held
              hereunder  to which the Fund  shall be  entitled  either by law or
              pursuant to custom in the securities business,  and shall promptly
              collect  all  income  and other  payments  with  respect to bearer
              securities  if,  on  the  date  of  payment  by the  issuer,  such
              securities  are held by the  Custodian or agent  thereof and shall
              credit such income, as collected, to the Fund's custodian account.

The Custodian  shall do all things  necessary and proper in connection with such
prompt  collections and,  without limiting the generality of the foregoing,  the
Custodian shall

              1)      Present for payment all coupons and other income items
                      requiring presentations;

              2)      Present for payment all securities  which may mature or be
                      called, redeemed, retired or otherwise become payable;

              3)      Endorse  and deposit  for  collection,  in the name of the
                      Fund, checks, drafts or other negotiable instruments;

              4)      Credit income from  securities  maintained in a Securities
                      System or in an Approved  Book-Entry System for Commercial
                      Paper at the time funds become available to the Custodian;
                      in the case of  securities  maintained  in The  Depository
                      Trust Company funds shall be deemed  available to the Fund
                      not  later  than the  opening  of  business  on the  first
                      business day after receipt of such funds by the Custodian.

<PAGE>


The Custodian shall notify the Fund as soon as reasonably  practicable  whenever
income due on any security is not promptly  collected.  In any case in which the
Custodian  does not receive any due and unpaid  income  after it has made demand
for the same,  it shall  immediately  so notify the Fund in  writing,  enclosing
copies of any demand letter, any written response thereto,  and memoranda of all
oral responses thereto and to telephonic  demands,  and await  instructions from
the Fund;  the Custodian  shall in no case have any liability for any nonpayment
of such income  provided the  Custodian  meets the standard of care set forth in
Section 8 hereof.  The Custodian shall not be obligated to take legal action for
collection unless and until reasonably indemnified to its satisfaction.

The  Custodian  shall also receive and collect all stock  dividends,  rights and
other  items  of like  nature,  and  deal  with  the  same  pursuant  to  proper
instructions relative thereto.

     H.       Payment of Fund Moneys Upon receipt of proper instructions,  which
              may be  continuing  instructions  when deemed  appropriate  by the
              parties,  the  Custodian  shall pay out  moneys of the Fund in the
              following cases only:

                      national  securities  exchange of which the Custodian is a
                      member  or by  any  bank,  banking  institution  or  trust
                      company  doing  business  in the  United  States or abroad

                      forth in Paragraph M hereof; (d) in the case of
                      repurchase agreements entered into between the Fund
                      and another bank or a broker-dealer, against receipt
                      by the Custodian of the securities underlying the
                      repurchase agreement either in certificate form or
                      through an entry crediting the Custodian's
                      segregated, non-proprietary account at the Federal
                      Reserve Bank of Boston with such securities along
                      with written evidence of the agreement by the bank or
                      broker-dealer to repurchase such securities from the
                      Fund; or (e) with respect to securities purchased

                      writing by the parties hereto;

              2)      When required in connection with the conversion,  exchange
                      or surrender of securities  owned by the Fund as set forth
                      in Paragraph B hereof;

              3)      When  required for the  redemption or repurchase of Shares
                      of the Fund in accordance with the provisions of Paragraph
                      J hereof;

              4)      For the  payment of any expense or  liability  incurred by
                      the  Fund,  including  but not  limited  to the  following
                      payments  for the  account  of the  Fund:  advisory  fees,
                      distribution plan payments,  interest,  taxes,  management
                      compensation and expenses, accounting,  transfer agent and
                      legal  fees,  and  other  operating  expenses  of the Fund
                      whether  or not such  expenses  are to be in whole or part
                      capitalized or treated as deferred expenses;

              5)      For the payment of any dividends or other distributions to
                      holders of Shares declared or authorized by the Board; and

              6)      For any  other  proper  corporate  purpose,  but only upon
                      receipt  of,  in  addition  to  proper   instructions,   a
                      certified  copy of a vote  of the  Board,  specifying  the
                      amount of such  payment,  setting  forth the  purpose  for
                      which such payment is to be made,  declaring  such purpose
                      to be a proper corporate purpose, and naming the person or
                      persons to whom such payment is to be made.

     I.       Liability for Payment in Advance of Receipt of Securities
              Purchased In any and every case where payment for purchase of
              securities for the account of the Fund is made by the
              Custodian in advance of receipt of the securities purchased in
              the absence of specific written instructions signed by two
              officers of the Fund to so pay in advance, the Custodian shall
              be absolutely liable to the Fund for such securities to the
              same extent as if the securities had been received by the
              Custodian; except that in the case of a repurchase agreement

<PAGE>


              entered into by the Fund with a bank which is a member of the
              Federal Reserve System, the Custodian may transfer funds to
              the account of such bank prior to the receipt of (i) the
              securities in certificate form subject to such repurchase
              agreement or (ii) written evidence that the securities subject
              to such repurchase agreement have been transferred by
              book-entry into a segregated non-proprietary account of the
              Custodian maintained with the Federal Reserve Bank of Boston
              or (iii) the safekeeping receipt, provided that such
              securities have in fact been so transferred by book-entry and
              the written repurchase agreement is received by the Custodian
              in due course; and except that if the securities are to be
              purchased outside the United States, payment may be made in
              accordance with procedures agreed to from time to time by the
              parties hereto.

     J.       Payments for Repurchases or Redemptions of Shares of the Fund From
              such funds as may be available for the purpose, but subject to any
              applicable  votes of the  Board  and the  current  redemption  and
              repurchase  procedures  of the Fund,  the  Custodian  shall,  upon
              receipt of written  instructions  from the Fund or from the Fund's
              transfer  agent  or from the  principal  underwriter,  make  funds
              and/or  portfolio  securities  available for payment to holders of
              Shares who have caused their Shares to be redeemed or  repurchased
              by the Fund or for the  Fund's  account by its  transfer  agent or
              principal underwriter.

              The Custodian may maintain a special  checking  account upon which
              special  checks may be drawn by  shareholders  of the Fund holding
              Shares for which certificates have not been issued.  Such checking
              account and such special checks shall be subject to such rules and
              regulations  as the  Custodian  and the Fund may from time to time
              adopt.  The  Custodian or the Fund may suspend or terminate use of
              such checking account or such special checks (either  generally or
              for one or more  shareholders)  at any time. The Custodian and the
              Fund shall notify the other  immediately of any such suspension or
              termination.

     K.       Appointment of Agents by the Custodian The Custodian may at
              any time or times in its discretion appoint (and may at any
              time remove) any other bank or trust company (provided such
              bank or trust company is itself qualified under the Investment
              Company Act of 1940 to act as a custodian or is itself an
              eligible foreign custodian within the meaning of Rule 17f-5
              under said Act) as the agent of the Custodian to carry out
              such of the duties and functions of the Custodian described in
              this Section 3 as the Custodian may from time to time direct;
              provided, however, that the appointment of any such agent
              shall not relieve the Custodian of any of its responsibilities
              or liabilities hereunder, and as between the Fund and the
              Custodian the Custodian shall be fully responsible for the
              acts and omissions of any such agent. For the purposes of this
              Agreement, any property of the Fund held by any such agent
              shall be deemed to be held by the Custodian hereunder.

              in each case only in accordance with  applicable  Federal Reserve
              Board  and   Securities   and  Exchange   Commission   rules  and
              regulations,   and  at  all  times   subject  to  the   following
              provisions:

     (a)      The  Custodian  may  (either  directly  or  through  one  or  more
              subcustodians  employed  pursuant to Section 2) keep securities of
              the Fund in a Securities  System provided that such securities are
              maintained  in  a  non-proprietary   account  ("Account")  of  the
              Custodian  or such  subcustodian  in the  Securities  System which
              shall not include any assets of the Custodian or such subcustodian
              or any other  person  other than assets held by the  Custodian  or
              such subcustodian as a fiduciary,  custodian, or otherwise for its
              customers.

     (b)      The records of the  Custodian  with respect to  securities  of the
              Fund which are maintained in a Securities System shall identify by
              book-entry  those  securities  belonging  to  the  Fund,  and  the
              Custodian   shall  be  fully  and   completely   responsible   for
              maintaining  a  recordkeeping  system  capable of  accurately  and
              currently  stating  the Fund's  holdings  maintained  in each such
              Securities System.

     (c)      The Custodian shall pay for securities purchased in
              book-entry form for the account of the Fund only upon (i)
              receipt of notice or advice from the Securities System that
              such securities have been transferred to the Account, and (ii)
              the making of any entry on the records of the Custodian to
              reflect such payment and transfer for the account of the Fund.
              The Custodian shall transfer securities sold for the account
              of the Fund only upon (i) receipt of notice or advice from the
              Securities System that payment for such securities has been
              transferred to the Account, and (ii) the making of an entry on
              the records of the Custodian to reflect such transfer and
              payment for the account of the Fund. Copies of all notices or

              promptly send to the Fund confirmation of each transfer to or
              from the account of the Fund in the form of a written advice
              or notice of each such transaction, and shall furnish to the
              Fund copies of daily transaction sheets reflecting each day's
              transactions in the Securities System for the account of the
              Fund on the next business day.

     (d)      The Custodian shall promptly send to the Fund any report

              subcustodians or of any of its or their employees or from any
              failure of the Custodian or any such agent or subcustodian to
              enforce effectively such rights as it may have against the
              Securities System or any other person; at the election of the

              the Custodian with respect to any claim against the Securities
              System or any other person which the Custodian may have as a
              consequence of any such loss or damage if and to the extent
              that the Fund has not been made whole for any such loss or

                  Foreign exchange contracts, swaps and options shall be deemed
                  to be portfolio securities of the Fund; and accordingly, the
                  responsibility of the Custodian therefor shall be the same as
                  and no greater than the Custodian's responsibility in respect
                  of other portfolio securities of the Fund. The Custodian shall
                  be responsible for the transmittal to and receipt of cash from
                  the currency broker or banking or financial institution with
                  which the contract or option is made, the maintenance of
                  proper records with respect to the transaction and the
                  maintenance of any segregated account required in connection
                  with the transaction. The Custodian shall have no duty with
                  respect to the selection of the currency brokers or banking or
                  financial institutions with which the Fund deals or for their
                  failure to comply with the terms of any contract or option.
                  Without limiting the foregoing, it is agreed that upon receipt
                  of proper instructions and insofar as funds are made available
                  to the Custodian for the purpose, the Custodian may (if
                  determined necessary by the Custodian to consummate a
                  particular transaction on behalf and for the account of the
                  Fund) make free outgoing payments of cash in the form of U.S.
                  dollars or foreign currency before receiving confirmation of a
                  foreign exchange contract or swap or confirmation that the
                  countervalue currency completing the foreign exchange contract
                  or swap has been delivered or received. The Custodian shall
                  not be responsible for any costs and interest charges which
                  may be incurred by the Fund or the Custodian as a result of
                  the failure or delay of third parties to deliver foreign
                  exchange; provided that the Custodian shall nevertheless be
                  held to the standard of care set forth in, and shall be liable
                  to the Fund in accordance with, the provisions of Section 8.

      V. Actions Permitted Without Express Authority The Custodian may in its
         discretion, without express authority from the Fund:

              1)      make  payments  to itself or others for minor  expenses of
                      handling securities or other similar items relating to its
                      duties  under  this  Agreement,  provided,  that  all such
                      payments  shall be accounted  for by the  Custodian to the
                      Treasurer of the Fund;

              2)      surrender securities in temporary form for securities in
                      definitive form;

              3)      endorse for collection, in the name of the Fund, checks,
                      drafts and other negotiable instruments; and

              4)      in  general,  attend to all  nondiscretionary  details  in
                      connection   with  the   sale,   exchange,   substitution,
                      purchase,  transfer and other dealings with the securities
                      and property of the Fund except as  otherwise  directed by
                      the Fund.

4. Duties of Bank with Respect to Books of Account and Calculations of Net Asset
   Value

The Bank shall as Agent (or as Custodian, as the case may be) keep such books of
account and render as at the close of business on each day a detailed  statement
of the amounts received or paid out and of securities  received or delivered for
the account of the Fund during said day and such other  statements,  including a
daily trial balance and inventory of the Fund's portfolio securities;  and shall
furnish such other financial information and data as from time to time requested
by the Treasurer or any  Authorized  Officer of the Fund;  and shall compute and
determine, as of the close of regular trading on the New York Stock Exchange, or
at such other time or times as the Board may determine, the net asset value of a
Share in the Fund, such  computation and  determination to be made in accordance
with the governing  documents of the Fund and the votes and  instructions of the
Board at the time in force and applicable,  and promptly notify the Fund and its
investment  adviser and such other persons as the Fund may request of the result
of such  computation  and  determination.  In computing  the net asset value the
Custodian may rely upon security  quotations  received by telephone or otherwise
from sources or pricing services designated by the Fund by proper  instructions,
and may further rely upon information  furnished to it by any Authorized Officer
of the Fund relative (a) to  liabilities  of the Fund not appearing on its books
of account, (b) to the existence,  status and proper treatment of any reserve or
reserves, (c) to any procedures established by the Board regarding the valuation
of portfolio securities,  and (d) to the value to be assigned to any bond, note,
debenture,  Treasury bill, repurchase agreement,  subscription right,  security,
participation  interest or other asset or property for which  market  quotations
are not readily available.

5. Records and Miscellaneous Duties

The Bank shall  create,  maintain  and  preserve  all  records  relating  to its
activities and obligations  under this Agreement in such manner as will meet the
obligations  of  the  Fund  under  the  Investment  Company  Act of  1940,  with
particular attention to Section 31 thereof and Rules 31a-1 and 31a-2 thereunder,
applicable federal and state tax laws and any other law or administrative  rules
or  procedures  which may be  applicable  to the Fund.  All books of account and
records  maintained by the Bank in connection with the performance of its duties
under  this  Agreement  shall be the  property  of the Fund,  shall at all times
during  the  regular  business  hours  of the  Bank be open  for  inspection  by
Authorized  Officers,  employees  or  agents  of the  Fund,  and in the event of

<PAGE>


termination  of this  Agreement  shall be delivered to the Fund or to such other
person or persons as shall be designated by the Fund. Disposition of any account
or record after any required period of preservation  shall be only in accordance
with  specific  instructions  received  from the  Fund.  The Bank  shall  assist
generally in the preparation of reports to shareholders, audits of accounts, and
other ministerial matters of like nature;  and, upon request,  shall furnish the
Fund's auditors with an attested  inventory of securities held with  appropriate
information  as to  securities  in transit or in the process of purchase or sale
and with such other  information as said auditors may from time to time request.
The  Custodian  shall also  maintain  records of all  receipts,  deliveries  and
locations of such securities,  together with a current  inventory  thereof,  and
shall  conduct  periodic   verifications   (including  sampling  counts  at  the
Custodian) of certificates  representing bonds and other securities for which it
is  responsible  under this  Agreement  in such  manner as the  Custodian  shall
determine  from time to time to be  advisable in order to verify the accuracy of
such  inventory.  The Bank shall not disclose or use any books or records it has
prepared  or  maintained  by reason of this  Agreement  in any manner  except as
expressly  authorized  herein or directed  by the Fund,  and the Bank shall keep
confidential any information obtained by reason of this Agreement.

6. Opinion of Fund's Independent Public Accountants

The Custodian  shall take all  reasonable  action,  as the Fund may from time to
time request,  to enable the Fund to obtain from year to year favorable opinions
from the Fund's  independent  public  accountants with respect to its activities
hereunder  in  connection  with  the  preparation  of  the  Fund's  registration
statement  and Form  N-SAR or  other  periodic  reports  to the  Securities  and
Exchange  Commission  and  with  respect  to  any  other  requirements  of  such
Commission.

7. Compensation and Expenses of Bank

The Bank shall be  entitled  to  reasonable  compensation  for its  services  as
Custodian  and Agent,  as agreed upon from time to time between the Fund and the
Bank. The Bank shall  entitled to receive from the Fund on demand  reimbursement
for its cash  disbursements,  expenses and charges,  including  counsel fees, in
connection  with its duties as  Custodian  and Agent  hereunder,  but  excluding
salaries and usual overhead expenses.

8. Responsibility of Bank

So long as and to the extent that it is in the exercise of reasonable  care, the
Bank as  Custodian  and Agent shall be held  harmless in acting upon any notice,
request,  consent,  certificate or other instrument reasonably believed by it to
be genuine and to be signed by the proper party or parties.

The Bank as  Custodian  and Agent  shall be entitled to rely on and may act upon
advice of counsel (who may be counsel for the Fund) on all matters, and shall be
without  liability for any action  reasonably  taken or omitted pursuant to such
advice.

The Bank as Custodian and Agent shall be held to the exercise of reasonable care
in carrying out the  provisions  of this  Agreement but shall be liable only for
its own  negligent  or bad faith acts or  failures to act.  Notwithstanding  the
foregoing,  nothing  contained in this  paragraph is intended to nor shall it be
construed  to  modify  the  standards  of care and  responsibility  set forth in
Section  2  hereof  with  respect  to  subcustodians  and in  subparagraph  f of
Paragraph  L of Section 3 hereof  with  respect  to  Securities  Systems  and in
subparagraph  g of  Paragraph M of Section 3 hereof with  respect to an Approved
Book-Entry System for Commercial Paper.
<PAGE>


The  Custodian  shall be liable for the acts or omissions  of a foreign  banking
institution  to the same  extent  as set forth  with  respect  to  subcustodians
generally in Section 2 hereof,  provided that,  regardless of whether assets are
maintained in the custody of a foreign banking institution, a foreign securities
depository or a branch of a U.S. bank, the Custodian shall not be liable for any
loss, damage,  cost,  expense,  liability or claim resulting from, or caused by,
the  direction  of or  authorization  by the  Fund to  maintain  custody  of any
securities or cash of the Fund in a foreign  county  including,  but not limited
to, losses resulting from nationalization, expropriation, currency restrictions,
acts of war,  civil war or  terrorism,  insurrection,  revolution,  military  or
usurped powers, nuclear fission, fusion or radiation, earthquake, storm or other
disturbance of nature or acts of God.

If the Fund requires the Bank in any capacity to take any action with respect to
securities,  which action  involves the payment of money or which action may, in
the opinion of the Bank,  result in the Bank or its nominee assigned to the Fund
being liable for the payment of money or incurring liability of some other form,
the Fund,  as a  prerequisite  to requiring  the  Custodian to take such action,
shall provide  indemnity to the Custodian in an amount and form  satisfactory to
it.

9. Persons Having Access to Assets of the Fund

              (i)     No trustee,  director,  general partner, officer, employee
                      or agent of the Fund  shall  have  physical  access to the
                      assets of the Fund held by the  Custodian or be authorized
                      or permitted to withdraw any  investments of the Fund, nor
                      shall the Custodian  deliver any assets of the Fund to any
                      such person. No officer or director,  employee or agent of
                      the Custodian who holds any similar position with the Fund
                      or the investment adviser of the Fund shall have access to
                      the assets of the Fund.

              (ii)    Access to assets of the Fund held hereunder  shall only be
                      available   to  duly   Authorized   Officers,   employees,
                      representatives  or  agents  of  the  Custodian  or  other
                      persons or entities for whose actions the Custodian  shall
                      be responsible to the extent  permitted  hereunder,  or to
                      the Fund's  independent  public  accountants in connection
                      with  their  auditing  duties  performed  on behalf of the
                      Fund.
<PAGE>


              (iii)   Nothing  in this  Section 9 shall  prohibit  any  officer,
                      employee or agent of the Fund or of the investment adviser
                      of the Fund from giving  instructions  to the Custodian or
                      executing a  certificate  so long as it does not result in
                      delivery of or access to assets of the Fund  prohibited by
                      paragraph (i) of this Section 9.

10.    Effective Period, Termination and Amendment; Successor Custodian

This Agreement  shall become  effective as of its  execution,  shall continue in
full force and effect until terminated as hereinafter  provided,  may be amended
at any time by mutual  agreement of the parties  hereto and may be terminated by
either party by an instrument in writing delivered or mailed, postage prepaid to
the other party, such termination to take effect not sooner than sixty (60) days
after the date of such delivery or mailing;  provided,  that the Fund may at any
time by action of its Board,  (i)  substitute  another bank or trust company for
the  Custodian by giving  notice as described  above to the  Custodian,  or (ii)
immediately  terminate  this  Agreement  in the  event of the  appointment  of a
conservator  or receiver  for the  Custodian  by the Federal  Deposit  Insurance
Corporation or by the Banking  Commissioner of The Commonwealth of Massachusetts
or upon  the  happening  of a like  event  at the  direction  of an  appropriate
regulatory  agency or court of competent  jurisdiction.  Upon termination of the
Agreement,  the Fund shall pay to the Custodian such  compensation as may be due
as of the date of such  termination  and shall likewise  reimburse the Custodian
for its costs, expenses and disbursements.

Unless the holders of a majority of the  outstanding  Shares of the Fund vote to
have the securities,  funds and other  properties  held hereunder  delivered and
paid over to some other bank or trust company, specified in the vote, having not
less than $2,000,000 of aggregate  capital,  surplus and undivided  profits,  as
shown by its last published report,  and meeting such other  qualifications  for
custodians  set forth in the  Investment  Company Act of 1940,  the Board shall,
forthwith,  upon giving or receiving  notice of termination  of this  Agreement,
appoint  as  successor   custodian,   a  bank  or  trust  company   having  such
qualifications.  The  Bank,  as  Custodian,  Agent  or  otherwise,  shall,  upon
termination  of  the  Agreement,   deliver  to  such  successor  custodian,  all
securities  then held  hereunder  and all funds or other  properties of the Fund
deposited  with or held by the  Bank  hereunder  and all  books of  account  and
records kept by the Bank pursuant to this  Agreement,  and all documents held by
the Bank  relative  thereto.  In the event that no such vote has been adopted by
the  shareholders  and that no written order  designating a successor  custodian
shall  have  been  delivered  to the  Bank  on or  before  the  date  when  such
termination  shall  become  effective,  then  the Bank  shall  not  deliver  the
securities,  funds and other  properties  of the Fund to the Fund but shall have
the right to  deliver  to a bank or trust  company  doing  business  in  Boston,
Massachusetts  of its own selection,  having an aggregate  capital,  surplus and
undivided  profits,  as shown by its last  published  report,  of not less  than
$2,000,000,  all  funds,  securities  and  properties  of the  Fund  held  by or
deposited  with the Bank,  and all books of account and records kept by the Bank
pursuant to this Agreement, and all documents held by the Bank relative thereto.
Thereafter  such bank or trust  company  shall be the successor of the Custodian
under this Agreement.
<PAGE>


11. Interpretive and Additional Provisions

In connection with the operation of this  Agreement,  the Custodian and the Fund
may from time to time agree on such provisions interpretive of or in addition to
the  provisions  of this  Agreement as may in their joint  opinion be consistent
with the general tenor of this  Agreement.  Any such  interpretive or additional
provisions  shall be in a writing  signed by both  parties  and shall be annexed
hereto,  provided  that no such  interpretive  or  additional  provisions  shall
contravene any applicable  federal or state  regulations or any provision of the
governing instruments of the Fund. No interpretive or additional provisions made
as provided in the preceding sentence shall be deemed to be an amendment of this
Agreement.

12. Certification as to Authorized Officers

The  Secretary  of the Fund  shall at all times  maintain  on file with the Bank
his/her  certification  to the Bank,  in such form as may be  acceptable  to the
Bank, of the names and  signatures of the  Authorized  Officers of each fund, it
being  understood  that upon the occurence of any change in the  information set
forth in the most recent certification on file (including without limitation any
person named in the most recent  certification who has ceased to hold the office
designated  therein),  the  Secretary  of the Fund  shall  sign a new or amended
certification setting forth the change and the new, additional or ommitted names
or  signatures.  The Bank shall be  entitled  to rely and act upon any  officers
named in the most recent certification.

13. Notices

Notices  and other  writings  delivered  or mailed  postage  prepaid to the Fund
addressed  to Susan S. Newton,  John  Hancock  Advisers,  Inc.,  101  Huntington
Avenue,  Boston,  Massachusetts  02199, or to such other address as the Fund may
have  designated  to the  Bank,  in  writing,  or to Attn:  Manager,  Securities
Department, Brown Brothers Harriman & Company, 40 Water Street, Boston, MA 02109
shall be  deemed to have  been  properly  delivered  or given  hereunder  to the
respective addressees.

14.     Massachusetts Law to Apply; Limitations on Liability

This Agreement shall be construed and the provisions  thereof  interpreted under
and in accordance with the laws of The Commonwealth of Massachusetts.

If  the  Fund  is  a  Massachusetts  business  trust,  the  Custodian  expressly
acknowledges  the  provision  in the Fund's  declaration  of trust  limiting the
personal  liability  of the  trustees  and  shareholders  of the  Fund;  and the
Custodian  agrees that it shall have recourse only to the assets of the Fund for
the  payment of claims or  obligations  as between  the  Custodian  and the Fund
arising out of this Agreement,  and the Custodian shall not seek satisfaction of
any such claim or obligation from the trustees or shareholders of the Fund. Each
Fund,  and each series or portfolio of a Fund,  shall be liable only for its own
obligations  to the Custodian  under this  Agreement and shall not be jointly or
severally  liable for the  obligations  of any other Fund,  series or  portfolio
hereunder.
<PAGE>


15.     Adoption of the Agreement by the Fund

The Fund  represents  that its Board has approved  this  Agreement  and has duly
authorized the Fund to adopt this  Agreement.  This Agreement shall be deemed to
supersede  and  terminate,  as of  the  date  first  written  above,  all  prior
agreements  between the Fund and the Bank  relating to the custody of the Fund's
assets.

RE:               John Hancock Series Trust (the "Trust")
                  on behalf of John Hancock Real Estate Fund (the "Fund")
                  File Nos. 2-75807; 811-3392 (0000357238)


Ladies and Gentlemen:

In  connection  with the  filing of Post  Effective  Amendment  No. 35 under the
Securities  Act of 1933, as amended,  and Amendment  No.38 under the  Investment
Company Act of 1940, as amended, for John Hancock Series Trust it is the opinion
of the  undersigned  that the Trust's  shares when sold will be legally  issued,
fully paid and nonassessable.

In connection with this opinion it should be noted that the Fund is an entity of
the type generally known as a "Massachusetts business trust." The Trust has been
duly  organized and is validly  existing under the laws of the  Commonwealth  of
Massachusetts. Under Massachusetts law, shareholders of a Massachusetts business
trust may be held personally  liable for the obligations of the Trust.  However,
the Trust's Declaration of Trust disclaims shareholder liability for obligations
of  the  Trust  and   indemnifies   the   shareholders  of  a  Fund,  with  this
indemnification to be paid solely out of the assets of that Fund. Therefore, the
shareholder's risk is limited to circumstances in which the assets of a Fund are
insufficient to meet the obligations asserted against that Fund's assets.


                                           Sincerely,


                                           /s/Alfred P. Ouellette
                                           ----------------------

         Article I.  This Plan

         This Distribution Plan (the "Plan") sets forth the terms and conditions

distribution  of Class R shares  of the  Fund,  including  expenses  related  to
printing of prospectuses and reports to other than existing Class R shareholders
of the Fund, and preparation,  printing and distribution of sales literature and
advertising  materials,  (c) an  allocation  of overhead and other branch office
expenses of JH Funds related to the  distribution of Class R shares of the Fund,
(d) interest expenses on unreimbursed  distribution  expenses related to Class R
shares,  as described in Article IV and (e)  distribution  expenses  incurred in
connection  with the  distribution  of a  corresponding  class of any  open-end,
registered investment company which sells all or substantially all its assets to
the Fund or which merges or otherwise combines with the Fund.

         Service  Expenses  include  payments  made to, or on account of account
executives  of selected  broker-dealers  (including  affiliates of JH Funds) and
others who furnish  personal and  shareholder  account  maintenance  services to

                      Class A, Class B, Class C and Class R

                   Multiple Class Plan Pursuant to Rule 18f-3

Each  class of shares of each of the John  Hancock  Funds  listed in  Appendix A
attached  hereto  (each the  "Fund")  will  have the same  relative  rights  and
privileges and be subject to the same sales charges,  fees and expenses,  except
as set forth  below.  The Board of  Trustees/Directors,  as the case may be, may
determine in the future that other  allocations of expenses (whether ordinary or
extraordinary)  or  other  services  to be  provided  to a class of  shares  are
appropriate and amend this Plan accordingly without the approval of shareholders
of any class.  Except as set forth in the Fund's  prospectus  and  statement  of
additional information  ("prospectus"),  shares may be exchanged only for shares
of the same class of another fund in the John Hancock group of funds.

Class A Shares

Class A Shares  are sold at net asset  value and  subject to the  initial  sales
charge  schedule or contingent  deferred  sales charge and the minimum  purchase
requirements set forth in the Fund's  prospectus.  Class A Shares are subject to
fees under the  Fund's  Class A Rule  12b-1  Distribution  Plan on the terms set
forth in the Fund's  prospectus.  The Class A Shareholders have exclusive voting
rights,  if any, with respect to the Class A Distribution  Plan.  Class A Shares
shall be entitled to the shareholder services set forth from time to time in the
Fund's prospectus with respect to Class A Shares.

Class B Shares

Class B Shares are sold at net asset value per share  without the  imposition of
an initial sales charge.  However,  Class B shares  redeemed  within a specified
number of years of  purchase  will be subject  to a  contingent  deferred  sales
charge as set forth in the Fund's prospectus. Class B Shares are sold subject to
the minimum purchase  requirements set forth in the Fund's  prospectus.  Class B
Shares are subject to fees under the Class B Rule 12b-1 Distribution Plan on the
terms set forth in the Fund's  prospectus.  The Class B Shareholders of the Fund
have  exclusive  voting  rights,  if any,  with  respect to the  Fund's  Class B
Distribution Plan. Class B Shares shall be entitled to the shareholder  services
set forth from time to time in the  Fund's  prospectus  with  respect to Class B
Shares.

Class B Shares will  automatically  convert to Class A Shares of the Fund at the
end of a specified  number of years after the initial  purchase  date of Class B
shares,  except as provided in the Fund's prospectus.  The initial purchase date
for Class B shares acquired through  reinvestment of dividends on Class B Shares
will be  deemed  to be the  date on  which  the  original  Class B  shares  were
purchased.  Such conversion will occur at the relative net asset value per share
of each class.  Redemption  requests placed by shareholders who own both Class A
and  Class B Shares  of the  Fund  will be  satisfied  first  by  redeeming  the
shareholder's  Class A  Shares,  unless  the  shareholder  has  made a  specific
election to redeem Class B Shares.

The  conversion  of Class B Shares to Class A Shares may be  suspended  if it is
determined that the conversion  constitutes or is likely to constitute a taxable
event under federal income tax law.
